Radek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The inhibition of histone deacetyles (HDACs) holds promise as a potential anti-cancer therapy because histone and non-histone protein acetylation is frequently disrupted in cancer, leading to cancer initiation and progression. Additionally, histone deacetylase inhibitors (HDACi) such as class I HDAC inhibitor - valproic acid (VPA) have been shown to enhance the effectiveness of DNA-damaging factors, such as cisplatin or radiation. In this study, we found that, using of VPA in combination with talazoparib (BMN-637 – PARP1 inhibitor – PARPi) and/or Dacarabazine (DTIC - alkylating agent) resulted in increased DNA double strand break (DSB) and reduced survival (while not affecting primary melanocytes )and proliferation of melanoma cells. Furthermore, pharmacologic inhibition of class I HDACs sensitizes melanoma cells to apoptosis following exposure to DTIC and BMN-637. In addition, inhibition of HDAC caused sensitization of melanoma cells to dacarbazine and BMN-637 in melanoma xenografts in vivo. At the mRNA and protein level histone deacetylase inhibitor downregulated RAD51 and FANCD2. This study provides that combining HDACi, alkylating agent and PARPi could potentially enhance the treatment of melanoma, which is known for being one of the most aggressive malignant tumors. The findings presented here point to a scenario in which HDAC via enhancing the HR-dependent repair of DSBs created during the processing of DNA lesions, are essential nodes in the resistance of malignant melanoma cells to methylating agent-based therapies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melanoma" title="melanoma">melanoma</a>, <a href="https://publications.waset.org/abstracts/search?q=hdac" title=" hdac"> hdac</a>, <a href="https://publications.waset.org/abstracts/search?q=parp%20inhibitor" title=" parp inhibitor"> parp inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=valproic%20acid" title=" valproic acid"> valproic acid</a> </p> <a href="https://publications.waset.org/abstracts/167232/histone-deacetylases-inhibitor-valproic-acid-sensitizes-human-melanoma-cells-for-alkylating-agent-and-parp-inhibitor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167232.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Great Art for Little Children - Games in School Education as Integration of Polish-Language, Eurhythmics, Artistic and Mathematical Subject Matter </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Anna%20Karczmarzyk">Małgorzata Anna Karczmarzyk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Who is the contemporary child?

However, the impact of different arm swing modes on gait stability is yet to be determined. This work intends to establish numerical parameters for assessing the arm swing. Nineteen people, comprising fifteen young, healthy individuals, two middle-aged individuals, and two individuals with dysfunctions, were analyzed using the movement analysis system. Proposed parameters such as ASᵢₐ (reflecting the arm swing amplitude) and Pearson’s correlation coefficient between the right and left upper limbs can be used to classify the type of movement task each participant performs. The results indicate that the ASᵢₐ parameter could potentially detect any abnormalities in upper limb functions, which may be due to musculoskeletal disorders or other malfunctions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arm%20swing" title="arm swing">arm swing</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20balance" title=" human balance"> human balance</a>, <a href="https://publications.waset.org/abstracts/search?q=interlimb%20coordination" title=" interlimb coordination"> interlimb coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20analysis%20system" title=" motion analysis system"> motion analysis system</a> </p> <a href="https://publications.waset.org/abstracts/164607/application-of-the-motion-analysis-system-to-formulate-parameters-defining-the-movement-of-the-upper-limbs-during-various-types-of-gait" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164607.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Fluorescent Imaging with Hoechst 34580 and Propidium Iodide in Determination of Toxic Changes of Cyanobacterial Oligopeptides in Rotifers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Bownik">Adam Bownik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Adamczuk"> Małgorzata Adamczuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Pawlik-Skowro%C5%84ska"> Barbara Pawlik-Skowrońska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Certain strains of cyanobacteria, microorganisms forming water blooms, produce toxic secondary metabolites. Although various effects of cyanotoxins in aquatic animals are known, little data can be found on the influence of some cyanobacterial oligopeptides beyond microcystins. The aim of the present study was to determine the toxicity of novel pure cyanobacterial oligopeptides: microginin FR-1 (MGFR1) and anabaenopeptin-A (ANA-A) on a transparent model rotifer Brachionus calyciflorus with the use of fluorescent double staining with Hoechst 34580 and propidium iodide. The obtained results showed that both studied oligopeptides decreased the fluorescence intensity of animals stained with Hoechst 34580 in a concentration-dependent manner. On the other hand, a concentration-dependent increase of propidium iodide fluorescence was noted in the exposed rotifers. The results suggest that MGFR-1 and ANA-A should be considered as a potent toxic agent to freshwater rotifers, and fluorescent staining with Hoechst and propidium iodide may be a valuable tool for determination of toxicity of cyanobacterial oligopeptides in rotifers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyanobacteria" title="cyanobacteria">cyanobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=brachionus" title=" brachionus"> brachionus</a>, <a href="https://publications.waset.org/abstracts/search?q=oligopeptides" title=" oligopeptides"> oligopeptides</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescent%20staining" title=" fluorescent staining"> fluorescent staining</a>, <a href="https://publications.waset.org/abstracts/search?q=hoechst" title=" hoechst"> hoechst</a>, <a href="https://publications.waset.org/abstracts/search?q=propidium%20iodide" title=" propidium iodide"> propidium iodide</a> </p> <a href="https://publications.waset.org/abstracts/146637/fluorescent-imaging-with-hoechst-34580-and-propidium-iodide-in-determination-of-toxic-changes-of-cyanobacterial-oligopeptides-in-rotifers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146637.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Postprandial Satiety, Sweets Intake, Physical Activity, and Depressive Symptoms in Relation to Rs9939609 Polymorphism of the FTO Gene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Wrzosek">Małgorzata Wrzosek</a>, <a href="https://publications.waset.org/abstracts/search?q=Nina%20Baruch"> Nina Baruch</a>, <a href="https://publications.waset.org/abstracts/search?q=Beata%20Jab%C5%82onowska-Lietz"> Beata Jabłonowska-Lietz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The fat mass & obesity-associated (FTO) gene is linked to an increased risk of obesity. However, the relation between rs9939609 and eating behaviors or energy expenditure is not fully elucidated. The aim of this study was to investigate the relationship between the rs9939609 polymorphism of the FTO gene and the postprandial satiety, sweets intake, physical activity and depressive symptoms in patients with obesity. Methods: The study group consisted of 585 subjects with a BMI of 42.97.0 kg/m². The rs9939609 polymorphism of the FTO gene was examined using real time – PCR method. The severity of depressive symptoms was assessed with the Beck Depression Inventory (BDI-II). Information was obtained about demographics, eating habits and lifestyle. Results: More than half (63.5%) of the patients reported consumption of sweets between main meals and 30% declared high and very high postprandial satiety and the frequency of TA/AA carriers in rs9939609 (FTO) compared with TT carriers was similar. Significantly lower BDI-II scores were found in subjects with higher level of physical activity and it was seen amongst patients with the AA and AT genotypes of the FTO rs9939609 polymorphism. Conclusion: Obesity is a highly heritable trait, but eating habits also appear as major factors affecting obesity development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FTO%20polymorphism" title="FTO polymorphism">FTO polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=postprandial%20satiety" title=" postprandial satiety"> postprandial satiety</a>, <a href="https://publications.waset.org/abstracts/search?q=sugary%20foods" title=" sugary foods"> sugary foods</a>, <a href="https://publications.waset.org/abstracts/search?q=sweets" title=" sweets"> sweets</a> </p> <a href="https://publications.waset.org/abstracts/153873/postprandial-satiety-sweets-intake-physical-activity-and-depressive-symptoms-in-relation-to-rs9939609-polymorphism-of-the-fto-gene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153873.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Gender Differences in Adolescent Avatars: Gender Consistency and Masculinity-Femininity of Nicknames and Characters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monika%20Paleczna">Monika Paleczna</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Holda"> Małgorzata Holda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Choosing an avatar's gender in a computer game is one of the key elements in the process of creating an online identity. The selection of a male or female avatar can define the entirety of subsequent decisions regarding both appearance and behavior. However, when the most popular games available for the Nintendo console in 1998 were analyzed, it turned out that 41% of computer games did not have female characters. Nowadays, players create their avatars based mainly on binary gender classification, with male and female characters to choose from. The main aim of the poster is to explore gender differences in adolescent avatars. 130 adolescents aged 15-17 participated in the study. They created their avatars and then played a computer game. The creation of the avatar was based on the choice of gender, then physical and mental characteristics. Data on gender consistency (consistency between participant’s sex and gender selected for the avatar) and masculinity-femininity of avatar nicknames and appearance will be presented. The masculinity-femininity of avatar nicknames and appearance was assessed by expert raters on a very masculine to very feminine scale. Additionally, data on the relationships of the perceived levels of masculinity-femininity with hostility-friendliness and the intelligence of avatars will be shown. The dimensions of hostility-friendliness and intelligence were also assessed by expert raters on scales ranging from very hostile to very friendly and from very low intelligence to very high intelligence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=avatar" title=" avatar"> avatar</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescence" title=" adolescence"> adolescence</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20games" title=" computer games"> computer games</a> </p> <a href="https://publications.waset.org/abstracts/137968/gender-differences-in-adolescent-avatars-gender-consistency-and-masculinity-femininity-of-nicknames-and-characters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Dying and Sexuality − Controversial Motive in Contemporary Cinema</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Jakubowska">Małgorzata Jakubowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Micha%C5%82owska"> Monika Michałowska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the beginning of the cinematographic industry, there has been a visible interest in two leading themes: death and sexuality. One of the reasons of the unfading popularity of these motives was the fact that death or sex employed as leitmotivs attracted great attention of the viewers, and this guaranteed a financial success. What seems interesting is the fact that the themes of death and sexuality/eroticism seem to be mutually exclusive in the mainstream movies to such extent that they almost never appear together on the screen. As leitmotivs they describe opposite experiences of human life, one refers to affirmation of life, the other points to atrophy and decay. This film paradigm is rarely challenged. Thus, a relatively less attention has been devoted so far to entwining dying and sexuality/eroticism in one movie. In our paper, we wish to have a closer look at the visualizations of dying with focus on the aspect of sexuality/eroticism. Our analysis will concentrate on the contemporary European and American cinema, and especially the recent productions that contribute to the cultural phenomenon of entwining the two realms of human life. We will investigate the main clichés, plot and visual schemes, motives and narrative techniques on the examples of Sweet November (2001), A Little Bit of Heaven (2011) and Now is good (2012). We will also shed some light on the recent film productions that seem to provide a shift in portraying the realms of dying and sexuality concentrating on The Garden of Earthly Delights (2003) as the most paradigmatic example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contemporary%20cinema" title="contemporary cinema">contemporary cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=dying%20and%20sexuality" title=" dying and sexuality"> dying and sexuality</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative%20techniques" title=" narrative techniques"> narrative techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=plot%20and%20visual%20schemes" title=" plot and visual schemes"> plot and visual schemes</a> </p> <a href="https://publications.waset.org/abstracts/35476/dying-and-sexuality-controversial-motive-in-contemporary-cinema" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35476.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Study on Temperature Distribution throughout the Continuous Casting Process of Copper Magnesium Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawe%C5%82%20Strz%C4%99pek">Paweł Strzępek</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Zasadzi%C5%84ska"> Małgorzata Zasadzińska</a>, <a href="https://publications.waset.org/abstracts/search?q=Szymon%20Kordaszewski"> Szymon Kordaszewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20%C5%9Aci%C4%99%C5%BCor"> Wojciech Ściężor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The constant tendency toward the materials properties improvement nowadays creates opportunities for the scientists, and furthermore the manufacturers all over the world to design, form and produce new alloys almost every day. Considering the fact that companies all over the world look for alloys with the highest values of mechanical properties coexisting with a reasonable electrical conductivity made it necessary to develop new materials based on copper, such as copper magnesium alloys with over 2 wt. % of Mg. Though, before such new material may be mass produced it must undergo a series of tests in order to determine the production technology and its parameters. The presented study is based on the numerical simulations calculated with the use of finite element method analysis, where the geometry of the cooling system, the material used to produce the cooling system and the surface quality of the graphite crystallizer at the place of contact with the cooling system and its influence on the temperatures throughout the continuous casting process is being investigated. The calculated simulations made it possible to propose the optimal set of equipment necessary for the continuous casting process to be carried out in laboratory conditions with various casting parameters and to determine basic materials properties of the obtained alloys such as hardness, electrical conductivity and homogeneity of the chemical composition.

Since 2012 the city Authorities have been working on implementing the plan, which assumed to reduce the energy consumption by 50%, and fully switch to renewable energy by the year 2050. To achieve this goal, the Municipality of Frankfurt has begun preparing the Master plan, which will be introduced to public by the end of 2015. A significant question when facing the starting of Master Plan public’s introduction was deciding which method should be used to increase the public engagement. In order to answer this question, the city and region authorities in the cooperation with Frankfurt’s Universities and Climate KIC, organized a two-week PhD scientific workshops, in which participated more than 30 students from numerous countries. The paper presented the outcome of the research and solution proposal of the winning team. Transitions theory tells, that to address challenges as complex as Climate Change and the Energiewende, using of new technologies and system to the public is not sufficient. Transition –by definition is a process, and in such a large scale (city and region transition) can be fulfilled only, when operates within a broad socio – technical system. Authors believe that only by close cooperation with city dwellers, as well as different stakeholders, the Transition in Frankfurt can be successful. The vital part is the strategy which will ensure the engagement, sense of ownership and broad support within Frankfurt society. Author proposal based therefore, on fostering the citizens engagement through a comprehensive, innovative communication strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=city%20development" title="city development">city development</a>, <a href="https://publications.waset.org/abstracts/search?q=communication%20strategies" title=" communication strategies"> communication strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20transition" title=" social transition"> social transition</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/27366/social-aspect-of-energy-transition-in-frankfurt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27366.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Determinants of Quality of Life and Mental Health in Medical Students During Two Years Observation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Szymon%20Szemik">Szymon Szemik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Kowalska"> Małgorzata Kowalska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Medical students experience numerous demands during the education process, determining their quality of life (QoL) and health status. POLLEK (POLski LEKarz, eng. Polish Physician) study aims to identify and evaluate the quality of life, mental health status, and ever-recognized chronic diseases by simultaneously assessing their determinants in Polish medical students during long-term observation. Material and Methods: The POLLEK is the follow-up cohort study conducted among medical students at the Medical University of Silesia in Katowice. Students were followed during two observation periods: in their first year of studies, the academic year 2021/2022 (T1), and in their second year, the academic year 2022/2023 (T2). Results: The total number of participants in the first year of observation (T1) was 427 while in the second year (T2) was 335. Obtained results confirmed that the QoL score significantly decreased in their second year of studies mainly in the somatic and psychological domains. Moreover, we observed a significant increase in self-declared scoring of somatic symptoms year by year (from M=4.75 at T1 to M=8.06 at T2, p<0.001) in the GHQ-28 questionnaire survey. The determinants of QoL domains common to T1 and T2 remained self-declared health status, frequency of physical activity, and current financial situation. In the first year of evaluation, 56 students (13.10%) were overweight or obese, and 52 (15.8%) in the second. Regardless of the academic year, the increased risk of being overweight or obese was significantly associated with dissatisfaction with personal health, financial deficiencies, and a diet abundant in meat consumption. Conclusions: The QoL in medical students and selected determinants of their health status deteriorated during the observation period. Our findings suggest that medical schools should actively promote the activity needed to achieve a balance between schoolwork and the personal life of medical students from the beginning of university study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title="quality of life">quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20students" title=" medical students"> medical students</a>, <a href="https://publications.waset.org/abstracts/search?q=follow-up%20study" title=" follow-up study"> follow-up study</a> </p> <a href="https://publications.waset.org/abstracts/186795/determinants-of-quality-of-life-and-mental-health-in-medical-students-during-two-years-observation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">40</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> The Influence of Phosphate Fertilizers on Radiological Situation of Cultivated Lands: ²¹⁰Po, ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs Concentrations in Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Szaci%C5%82owski">Grzegorz Szaciłowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Konop"> Marta Konop</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Dymecka"> Małgorzata Dymecka</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20O%C5%9Bko"> Jakub Ośko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 1996, the European Council Directive 96/29/EURATOM pointed phosphate fertilizers to have a potentially negative influence on the environment from the radiation protection point of view. Fertilizers along with irrigation and crop rotation were the milestones that allowed to increase agricultural productivity. Firstly based on natural materials such as compost, manure, fish processing waste, etc., and since the 19th century created synthetically, fertilizers caused a boom in crop yield and helped to propel global food production, especially after World War II. In this work the concentrations of ²¹⁰Po, ²²⁶Ra, ²³²Th, ⁴⁰K, and ¹³⁷Cs in selected fertilizers and soil samples were determined. The results were used to calculate the annual addition of natural radionuclides and increment of the external radiation exposure caused by the use of studied fertilizers. Soils intended for different types of crops were sampled in early spring when no vegetation had occurred yet. Analysed fertilizers were those with which the soil was previously fertilized. For gamma radionuclides, a high purity germanium detector GX3520 from Canberra was used. The polonium concentration was determined by radiochemical separation followed by measurement by means of alpha spectrometry. The spectrometer used in this study was equipped with 450 cm² PIPS detector from Canberra. Obtained results showed significant differences in radionuclide composition between phosphate and nitrogenous fertilizers (e.g. the radium equivalent activity for phosphate fertilizer was 207.7 Bq/kg in comparison to <5.6 Bq/kg for nitrogenous fertilizer). The calculated increase of external radiation exposure due to use of phosphate fertilizer ranged between 3.4 and 5.4 nG/h, which represents up to 10% of the polish average outdoor exposure due to terrestrial gamma radiation (45 nGy/h). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C2%B2%C2%B9%E2%81%B0Po" title="²¹⁰Po">²¹⁰Po</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha%20spectrometry" title=" alpha spectrometry"> alpha spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure" title=" exposure"> exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20spectrometry" title=" gamma spectrometry"> gamma spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphate%20fertilizer" title=" phosphate fertilizer"> phosphate fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a> </p> <a href="https://publications.waset.org/abstracts/143407/the-influence-of-phosphate-fertilizers-on-radiological-situation-of-cultivated-lands-21po-226ra-232th-4k-and-137cs-concentrations-in-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143407.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">300</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Shaping and Improving the Human Resource Management in Small and Medium Enterprises in Poland </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Smolarek">Małgorzata Smolarek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the barriers to the development of small and medium-sized enterprises (SME) are difficulties connected with management of human resources. The first part of article defines the specifics of staff management in small and medium enterprises. The practical part presents results of own studies in the area of diagnosis of the state of the human resources management in small and medium-sized enterprises in Poland. It takes into account its impact on the functioning of SME in a variable environment. This part presents findings of empirical studies, which enabled verification of the hypotheses and formulation of conclusions. The findings presented in this paper were obtained during the implementation of the project entitled 'Tendencies and challenges in strategic managing SME in Silesian Voivodeship.' The aim of the studies was to diagnose the state of strategic management and human resources management taking into account its impact on the functioning of small and medium enterprises operating in Silesian Voivodeship in Poland and to indicate improvement areas of the model under diagnosis. One of the specific objectives of the studies was to diagnose the state of the process of strategic management of human resources and to identify fundamental problems. In this area, the main hypothesis was formulated: The enterprises analysed do not have comprehensive strategies for management of human resources. The survey was conducted by questionnaire. Main Research Results: Human resource management in SMEs is characterized by simplicity of procedures, and the lack of sophisticated tools and its specificity depends on the size of the company. The process of human resources management in SME has to be adjusted to the structure of an organisation, result from its objectives, so that an organisation can fully implement its strategic plans and achieve success and competitive advantage on the market. A guarantee of success is an accurately developed policy of human resources management based on earlier analyses of the existing procedures and possessed human resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20resources%20management" title="human resources management">human resources management</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20resources%20policy" title=" human resources policy"> human resources policy</a>, <a href="https://publications.waset.org/abstracts/search?q=personnel%20strategy" title=" personnel strategy"> personnel strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20and%20medium%20enterprises" title=" small and medium enterprises"> small and medium enterprises</a> </p> <a href="https://publications.waset.org/abstracts/76135/shaping-and-improving-the-human-resource-management-in-small-and-medium-enterprises-in-poland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76135.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">241</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Assessment of Platelet and Lymphocyte Interaction in Autoimmune Hyperthyroidism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Tomczy%C5%84ska">Małgorzata Tomczyńska</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Saluk-Bijak"> Joanna Saluk-Bijak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Graves’ disease is a frequent organ-specific autoimmune thyroid disease, which characterized by the presence of different kind autoantibodies, that, in most cases, act as agonists of the thyrotropin receptor, leading to hyperthyroidism. Role of platelets and lymphocytes can be modulated in the pathophysiology of thyroid autoimmune diseases. Interference in the physiology of platelets can lead to enhanced activity of these cells. Activated platelets can bind to circulating lymphocytes and to affect lymphocyte adhesion. Platelets and lymphocytes can regulate mutual functions. Therefore, the activation of T lymphocytes, as well as blood platelets, is associated with the development of inflammation and oxidative stress within the target tissue. The present study was performed to investigate a platelet-lymphocyte relation by assessing the degree of their mutual aggregation in whole blood of patients with Graves’ disease. Also, the purpose of this study was to examine the impact of platelet interaction on lymphocyte migration capacity. Methods: 30 patients with Graves’ disease were recruited in the study. The matched 30 healthy subjects were served as the control group. Immunophenotyping of lymphocytes was carried out by flow cytometry method. A CytoSelect™ Cell Migration Assay Kit was used to evaluate lymphocyte migration and adhesion to blood platelets. Visual assessment of lymphocyte-platelet aggregate morphology was done using confocal microscope after magnetic cell isolation by Miltenyi Biotec. Results: The migration and functional responses of lymphocytes to blood platelets were greater in the group of Graves’ disease patients compared with healthy controls. The group of Graves’ disease patients exhibited a reduced T lymphocyte and a higher B cell count compared with controls. Based on microscopic analysis, more platelet-lymphocyte aggregates were found in patients than in control. Conclusions: Studies have shown that in Graves' disease, lymphocytes show increased platelet affinity, more strongly migrating toward them, and forming mutual cellular conglomerates. This may be due to the increased activation of blood platelets in this disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20platelets" title="blood platelets">blood platelets</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20migration" title=" cell migration"> cell migration</a>, <a href="https://publications.waset.org/abstracts/search?q=Graves%E2%80%99%20disease" title=" Graves’ disease"> Graves’ disease</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphocytes" title=" lymphocytes"> lymphocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=lymphocyte-platelet%20aggregates" title=" lymphocyte-platelet aggregates"> lymphocyte-platelet aggregates</a> </p> <a href="https://publications.waset.org/abstracts/78333/assessment-of-platelet-and-lymphocyte-interaction-in-autoimmune-hyperthyroidism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">227</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Impact of Expressive Writing on Creativity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Osowiecka">Małgorzata Osowiecka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Negative emotions are rather seen as creativity inhibitor. On the other hand, it is worth noting that negative emotions may be good for our functioning. Negative emotions enhance cognitive resources and improve evaluative processes. Moreover maintaining a negative emotional state allow for cognitive reinterpretation of the emotional stimuli, what is good for our creativity, especially cognitive flexibility. Writing a diary or writing about difficult emotional experiences in general can be the way to not only improve psychical health, but also – enhance creative behaviors. Thanks to translating difficult emotions to the verbal level and giving them ‘a name’ or ‘a label’, we can get easier access to both emotional content of an experience and to the semantic content, without the need of speaking out loud. Expressive writing improves academic results and the efficiency of working memory. The classical method of writing about emotions consists in a long-term process of describing negative experiences. Present research demonstrate the efficiency of this process over a shorter period of time - one writing session, on school children sample. Participants performed writing task. Writing task had two different topics: emotions connected with their negative emotions (expressive writing) and content not connected with negative emotional state (writing about one’s typical day). Creativity was measured by Guilford’s Alternative Uses Task. Results have shown that writing about negative emotions results in the higher level of divergent thinking in all three parameters: fluency, flexibility and originality. After the writing task mood of expressive writing participants remained negative more than the mood of the controls. Taking an expressive action after a difficult emotional experience can support functioning, which can be observed in enhancement of divergent thinking. Writing about emotions connected with negative experience makes one more creative, than writing about something unrelated with difficult emotional moments. Research has shown that young people should not demonize negative emotions. Sometimes, properly applied, negative emotions can be the basis of creation. Preparation was supported by a The Young Scientist University grant titled ‘Dynamics of emotions in the creative process’ from The Polish Ministry of Science and Higher Education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=divergent%20thinking" title=" divergent thinking"> divergent thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=emotions" title=" emotions"> emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=expressive%20writing" title=" expressive writing"> expressive writing</a> </p> <a href="https://publications.waset.org/abstracts/62317/impact-of-expressive-writing-on-creativity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62317.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Relationship between Prolonged Timed up and Go Test and Worse Cardiometabolic Diseases Risk Factors Profile in a Population Aged 60-65 Years</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bart%C5%82omiej%20K.%20So%C5%82tysik">Bartłomiej K.

Functional capacity may be influenced by multiple disorders, including cardiovascular and metabolic diseases. Nevertheless, there is relatively little evidence regarding the association of functional status and cardiometabolic risk factors. Aim: The aim of this research is to check possible association between functional capacity and cardiovascular risk factor in a group of younger seniors. Materials and Methods: The study group consisted of 300 participants aged 60-65 years (50% were women). Total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), glucose, uric acid, body mass index (BMI), waist-to-height ratio (WHtR) and blood pressure were measured. Smoking status and physical activity level (by Seven Day Physical Activity Recall Questionnaire ) were analysed. Functional status was assessed with the Timed Up and Go (TUG) Test. The data were compared according to gender, and then separately for both sexes regarding prolonged TUG score (>7 s). The limit of significance was set at p≤0.05 for all analyses. Results: Women presented with higher serum lipids and longer TUG. Men had higher blood pressure, glucose, uric acid, the prevalence of hypertension and history of heart infarct. In women group, those with prolonged TUG displayed significantly higher obesity rate (BMI, WHTR), uric acid, hypertension and ischemic heart disease (IHD), but lower physical activity level, TC or LDL-C. Men with prolonged TUG were heavier smokers, had higher TG, lower HDL and presented with higher prevalence of diabetes and IHD. Discussion: This study shows association between functional status and risk profile of cardiometabolic disorders. In women, the relationship of lower functional status to cardiometabolic diseases may be mediated by overweight/obesity. In men, locomotor problems may be related to smoking. Higher education level may be considered as a protective factor regardless of gender. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20risk%20factors" title="cardiovascular risk factors">cardiovascular risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20capacity" title=" functional capacity"> functional capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=TUG%20test" title=" TUG test"> TUG test</a>, <a href="https://publications.waset.org/abstracts/search?q=seniors" title=" seniors"> seniors</a> </p> <a href="https://publications.waset.org/abstracts/60679/relationship-between-prolonged-timed-up-and-go-test-and-worse-cardiometabolic-diseases-risk-factors-profile-in-a-population-aged-60-65-years" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The Role of Situational Attribution Training in Reducing Automatic In-Group Stereotyping in Females</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olga%20Mironiuk">Olga Mironiuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Kossowska"> Małgorzata Kossowska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present study was to investigate the influence of Situational Attribution Training on reducing automatic in-group stereotyping in females. The experiment was conducted with the control of age and level of prejudice. 90 female participants were randomly assigned to two conditions: experimental and control group (each group was also divided into younger- and older-aged condition). Participants from the experimental condition were subjected to more extensive training. In the first part of the experiment, the experimental group took part in the first session of Situational Attribution Training while the control group participated in the Grammatical Training Control. In the second part of the research both groups took part in the Situational Attribution Training (which was considered as the second training session for the experimental group and the first one for the control condition). The training procedure was based on the descriptions of ambiguous situations which could be explained using situational or dispositional attributions. The participant’s task was to choose the situational explanation from two alternatives, out of which the second one presented the explanation based on neutral or stereotypically associated with women traits. Moreover, the experimental group took part in the third training session after two- day time delay, in order to check the persistence of the training effect. The main hypothesis stated that among participants taking part in the more extensive training, the automatic in-group stereotyping would be less frequent after having finished training sessions. The effectiveness of the training was tested by measuring the response time and the correctness of answers: the longer response time for the examples where one of two possible answers was based on the stereotype trait and higher correctness of answers was considered to be a proof of the training effectiveness. As the participants’ level of prejudice was controlled (using the Ambivalent Sexism Inventory), it was also assumed that the training effect would be weaker for participants revealing a higher level of prejudice. The obtained results did not confirm the hypothesis based on the response time: participants from the experimental group responded faster in case of situations where one of the possible explanations was based on stereotype trait. However, an interesting observation was made during the analysis of the answers’ correctness: regardless the condition and age group affiliation, participants made more mistakes while choosing the situational explanations when the alternative was based on stereotypical trait associated with the dimension of warmth. What is more, the correctness of answers was higher in the third training session for the experimental group in case when the alternative of situational explanation was based on the stereotype trait associated with the dimension of competence. The obtained results partially confirm the effectiveness of the training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=female" title="female">female</a>, <a href="https://publications.waset.org/abstracts/search?q=in-group%20stereotyping" title=" in-group stereotyping"> in-group stereotyping</a>, <a href="https://publications.waset.org/abstracts/search?q=prejudice" title=" prejudice"> prejudice</a>, <a href="https://publications.waset.org/abstracts/search?q=situational%20attribution%20training" title=" situational attribution training"> situational attribution training</a> </p> <a href="https://publications.waset.org/abstracts/72813/the-role-of-situational-attribution-training-in-reducing-automatic-in-group-stereotyping-in-females" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72813.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Analysis of the Content of Sugars, Vitamin C, Preservatives, Synthetic Dyes, Sweeteners, Sodium and Potassium and Microbiological Purity in Selected Products Made From Fruit and Vegetables in Small Regional Factories and in Large Food Corporations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Mi%C5%9Bkiewicz">Katarzyna Miśkiewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Laso%C5%84-Rydel"> Magdalena Lasoń-Rydel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Kr%C4%99pska"> Małgorzata Krępska</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Sieczy%C5%84ska"> Katarzyna Sieczyńska</a>, <a href="https://publications.waset.org/abstracts/search?q=Iwona%20Mas%C5%82owska-Lipowicz"> Iwona Masłowska-Lipowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20%C5%81awi%C5%84ska"> Katarzyna Ławińska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study was to analyse a selection of 12 pasteurised products made from fruit and vegetables, such as fruit juices, fruit drinks, jams, marmalades and jam produced by small regional factories as well as large food corporations. The research was carried out as part of the project "Innovative system of healthy and regional food distribution", funded by the Ministry of Education and Science (Poland), which aims to create an economically and organisationally strong agri-food industry in Poland through effective cooperation between scientific and socio-economic actors. The main activities of the project include support for the creation of new distribution channels for regional food products and their easy access to a wide group of potential customers while maintaining the highest quality standards. One of the key areas of the project is food quality analyses conducted to indicate the competitive advantage of regional products. Presented here are studies on the content of sugars, vitamin C, preservatives, synthetic colours, sweeteners, sodium and potassium, as well as studies on the microbiological purity of selected products made from fruit and vegetables. The composition of products made from fruit and vegetables varies greatly and depends on both the type of raw material and the way it is processed. Of the samples tested, fruit drinks contained the least amount of sugars, and jam and marmalade made by large producers and bought in large chain stores contained the most. However, the low sugar content of some fruit drinks is due to the presence of the sweetener sucralose in their composition. The vitamin C content of the samples varied, being higher in products where it was added during production. All products made in small local factories were free of food additives such as preservatives, sweeteners and synthetic colours, indicating their superiority over products made by large producers. Products made in small local factories were characterised by a relatively high potassium content. The microbiological purity of commercial products was confirmed - no Salmonella spp. were detected, and the number of mesophilic bacteria, moulds, yeasts, and β-glucuronidase-positive E. coli was below the limit of quantification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fruit%20and%20vegetable%20products" title="fruit and vegetable products">fruit and vegetable products</a>, <a href="https://publications.waset.org/abstracts/search?q=sugars" title=" sugars"> sugars</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20additives" title=" food additives"> food additives</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC" title=" HPLC"> HPLC</a>, <a href="https://publications.waset.org/abstracts/search?q=ICP-OES" title=" ICP-OES"> ICP-OES</a> </p> <a href="https://publications.waset.org/abstracts/176082/analysis-of-the-content-of-sugars-vitamin-c-preservatives-synthetic-dyes-sweeteners-sodium-and-potassium-and-microbiological-purity-in-selected-products-made-from-fruit-and-vegetables-in-small-regional-factories-and-in-large-food-corporations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176082.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Assessment of the Properties of Microcapsules with Different Polymeric Shells Containing a Reactive Agent for their Suitability in Thermoplastic Self-healing Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Golonka">Małgorzata Golonka</a>, <a href="https://publications.waset.org/abstracts/search?q=Jadwiga%20Laska"> Jadwiga Laska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-healing polymers are one of the most investigated groups of smart materials. As materials engineering has recently focused on the design, production and research of modern materials and future technologies, researchers are looking for innovations in structural, construction and coating materials. Based on available scientific articles, it can be concluded that most of the research focuses on the self-healing of cement, concrete, asphalt and anticorrosion resin coatings. In our study, a method of obtaining and testing the properties of several types of microcapsules for use in self-healing polymer materials was developed. A method to obtain microcapsules exhibiting various mechanical properties, especially compressive strength was developed. The effect was achieved by using various polymer materials to build the shell: urea-formaldehyde resin (UFR), melamine-formaldehyde resin (MFR), melamine-urea-formaldehyde resin (MUFR). Dicyclopentadiene (DCPD) was used as the core material due to the possibility of its polymerization according to the ring-opening olefin metathesis (ROMP) mechanism in the presence of a solid Grubbs catalyst showing relatively high chemical and thermal stability. The ROMP of dicyclopentadiene leads to a polymer with high impact strength, high thermal resistance, good adhesion to other materials and good chemical and environmental resistance, so it is potentially a very promising candidate for the self-healing of materials. The capsules were obtained by condensation polymerization of formaldehyde with urea, melamine or copolymerization with urea and melamine in situ in water dispersion, with different molar ratios of formaldehyde, urea and melamine. The fineness of the organic phase dispersed in water, and consequently the size of the microcapsules, was regulated by the stirring speed. In all cases, to establish such synthesis conditions as to obtain capsules with appropriate mechanical strength. The microcapsules were characterized by determining the diameters and their distribution and measuring the shell thickness using digital optical microscopy and scanning electron microscopy, as well as confirming the presence of the active substance in the core by FTIR and SEM. Compression tests were performed to determine mechanical strength of the microcapsules. The highest repeatability of microcapsule properties was obtained for UFR resin, while the MFR resin had the best mechanical properties. The encapsulation efficiency of MFR was much lower compared to UFR, though. Therefore, capsules with a MUFR shell may be the optimal solution. The chemical reaction between the active substance present in the capsule core and the catalyst placed outside the capsules was confirmed by FTIR spectroscopy. The obtained autonomous repair systems (microcapsules + catalyst) were introduced into polyethylene in the extrusion process and tested for the self-repair of the material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomic%20self-healing%20system" title="autonomic self-healing system">autonomic self-healing system</a>, <a href="https://publications.waset.org/abstracts/search?q=dicyclopentadiene" title=" dicyclopentadiene"> dicyclopentadiene</a>, <a href="https://publications.waset.org/abstracts/search?q=melamine-urea-formaldehyde%20resin" title=" melamine-urea-formaldehyde resin"> melamine-urea-formaldehyde resin</a>, <a href="https://publications.waset.org/abstracts/search?q=microcapsules" title=" microcapsules"> microcapsules</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoplastic%20materials" title=" thermoplastic materials"> thermoplastic materials</a> </p> <a href="https://publications.waset.org/abstracts/186378/assessment-of-the-properties-of-microcapsules-with-different-polymeric-shells-containing-a-reactive-agent-for-their-suitability-in-thermoplastic-self-healing-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186378.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">45</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Comparative Study for Neonatal Outcome and Umbilical Cord Blood Gas Parameters in Balanced and Inhalant Anesthesia for Elective Cesarean Section in Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Anto%C5%84czyk">Agnieszka Antończyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82Gorzata%20Ochota"> MałGorzata Ochota</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20Ni%C5%BCa%C5%84ski"> Wojciech Niżański</a>, <a href="https://publications.waset.org/abstracts/search?q=Zdzis%C5%82Aw%20Kie%C5%82bowicz"> ZdzisłAw Kiełbowicz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of the cesarean section (CS) is the delivery of healthy, vigorous pups with the provision of surgical plane anesthesia, appropriate analgesia, and rapid recovery of the dam. In human medicine, spinal or epidural anesthesia is preferred for a cesarean section as associated with a lower risk of neonatal asphyxia and the need for resuscitation. Nevertheless, the specificity of veterinary patients makes the application of regional anesthesia as a sole technique impractical, thus to obtain patient compliance the general anesthesia is required. This study aimed to compare the influence of balanced (inhalant with epidural) and inhalant anesthesia on neonatal umbilical cord blood gas (UCBG) parameters and vitality (modified Apgar scoring). The bitches (31) undergoing elective CS were enrolled in this study. All females received a single dose of 0.2 mg/kg s.c. Meloxicam. Females were randomly assigned into two groups: Gr I (Isoflurane, n=16) and Gr IE (Isoflurane plus Epidural, n=15). Anesthesia was induced with propofol at 4-6 mg/kg to effect, and maintained with isoflurane in oxygen; in IE group epidural anesthesia was also done using lidocaine (3-4 mg/kg) into the lumbosacral space. CSs were performed using a standard mid-line approach. Directly after the puppy extraction, the umbilical cord was double clamped before the placenta detachment. The vessels were gently stretched between forceps to allow blood sampling. At least 100 mcl of mixed umbilical cord blood was collected into a heparinized syringe for further analysis. The modified Apgar scoring system (AS) was used to objectively score neonatal health and vitality immediately after birth (before first aid or neonatal care was instituted), at 5 and 20 min after birth. The neonates were scored as normal (AS 7-10), weak (AS 4-6), or critical (AS 0-3). During surgery, the IE group required a lower isoflurane concentration compared to the females in group I (MAC 1.05±0.2 and 1.4±0.13, respectively, p<0.01). All investigated UCBG parameters were not statistically different between groups. All pups had mild acidosis (pH 7.21±0.08 and 7.21±0.09 in Gr I and IE, respectively) with moderately elevated pCO2 (Gr I 57.18±11.48, Gr IE 58.74±15.07), HCO3- on the lower border (Gr I 22.58±3.24, Gr IE 22.83±3.6), lowered BE (Gr I -6.1±3.57, Gr IE -5.6±4.19) and mildly elevated level of lactates (Gr I 2.58±1.48, Gr IE2.53±1.03). The glucose levels were above the reference limits in both groups of puppies (74.50±25.32 in Gr I, 79.50±29.73 in Gr IE). The initial Apgar score results were similar in I and IE groups. However, the subsequent measurements of AS revealed significant differences between both groups. Puppies from the IE group received better AS scores at 5 and 20 min compared to the I group (6.86±2.23 and 8.06±2.06 vs 5.11±2.40 and 7.83±2.05, respectively). The obtained results demonstrated that administration of epidural anesthesia reduced the requirement for isoflurane in dams undergoing cesarean section and did not affect the neonatal umbilical blood gas results. Moreover, newborns from the epidural anesthesia group were scored significantly higher in AS at 5 and 20 min, indicating their better vitality and quicker improvement post-surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apgar%20scoring" title="apgar scoring">apgar scoring</a>, <a href="https://publications.waset.org/abstracts/search?q=balanced%20anesthesia" title=" balanced anesthesia"> balanced anesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=cesarean%20section" title=" cesarean section"> cesarean section</a>, <a href="https://publications.waset.org/abstracts/search?q=umbilical%20blood%20gas" title=" umbilical blood gas"> umbilical blood gas</a> </p> <a href="https://publications.waset.org/abstracts/137031/comparative-study-for-neonatal-outcome-and-umbilical-cord-blood-gas-parameters-in-balanced-and-inhalant-anesthesia-for-elective-cesarean-section-in-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137031.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Characteristics of Bio-hybrid Hydrogel Materials with Prolonged Release of the Model Active Substance as Potential Wound Dressings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Bialik-W%C4%85s">Katarzyna Bialik-Wąs</a>, <a href="https://publications.waset.org/abstracts/search?q=Klaudia%20Pluta"> Klaudia Pluta</a>, <a href="https://publications.waset.org/abstracts/search?q=Dagmara%20Malina"> Dagmara Malina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Miastkowska"> Małgorzata Miastkowska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, biocompatible hydrogels have been used more and more in medical applications, especially as modern dressings and drug delivery systems. The main goal of this research was the characteristics of bio-hybrid hydrogel materials incorporated with the nanocarrier-drug system, which enable the release in a gradual and prolonged manner, up to 7 days. Therefore, the use of such a combination will provide protection against mechanical damage and adequate hydration. The proposed bio-hybrid hydrogels are characterized by: transparency, biocompatibility, good mechanical strength, and the dual release system, which allows for gradual delivery of the active substance, even up to 7 days. Bio-hybrid hydrogels based on sodium alginate (SA), poly(vinyl alcohol) (PVA), glycerine, and Aloe vera solution (AV) were obtained through the chemical crosslinking method using poly(ethylene glycol) diacrylate as a crosslinking agent. Additionally, a nanocarrier-drug system was incorporated into SA/PVA/AV hydrogel matrix. Here, studies were focused on the release profiles of active substances from bio-hybrid hydrogels using the USP4 method (DZF II Flow-Through System, Erweka GmbH, Langen, Germany). The equipment incorporated seven in-line flow-through diffusion cells. The membrane was placed over support with an orifice of 1,5 cm in diameter (diffusional area, 1.766 cm²). All the cells were placed in a cell warmer connected with the Erweka heater DH 2000i and the Erweka piston pump HKP 720. The piston pump transports the receptor fluid via seven channels to the flow-through cells and automatically adapts the setting of the flow rate. All volumes were measured by gravimetric methods by filling the chambers with Milli-Q water and assuming a density of 1 g/ml. All the determinations were made in triplicate for each cell. The release study of the model active substance was carried out using a regenerated cellulose membrane Spectra/Por®Dialysis Membrane MWCO 6-8,000 Carl Roth® Company. These tests were conducted in buffer solutions – PBS at pH 7.4. A flow rate of receptor fluid of about 4 ml /1 min was selected. The experiments were carried out for 7 days at a temperature of 37°C. The released concentration of the model drug in the receptor solution was analyzed using UV-Vis spectroscopy (Perkin Elmer Company). Additionally, the following properties of the modified materials were studied: physicochemical, structural (FT-IR analysis), morphological (SEM analysis). Finally, the cytotoxicity tests using in vitro method were conducted. The obtained results exhibited that the dual release system allows for the gradual and prolonged delivery of the active substances, even up to 7 days. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wound%20dressings" title="wound dressings">wound dressings</a>, <a href="https://publications.waset.org/abstracts/search?q=SA%2FPVA%20hydrogels" title=" SA/PVA hydrogels"> SA/PVA hydrogels</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocarrier-drug%20system" title=" nanocarrier-drug system"> nanocarrier-drug system</a>, <a href="https://publications.waset.org/abstracts/search?q=USP4%20method" title=" USP4 method"> USP4 method</a> </p> <a href="https://publications.waset.org/abstracts/144199/characteristics-of-bio-hybrid-hydrogel-materials-with-prolonged-release-of-the-model-active-substance-as-potential-wound-dressings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144199.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Effect of Noise at Different Frequencies on Heart Rate Variability - Experimental Study Protocol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bortkiewcz">A.

It is usually considered a broadband noise with the dominant content of low frequencies from 10 Hz to 250 Hz. A growing body of data shows that LFN differs in nature from other environmental noises, which are at comparable levels but not dominated by low-frequency components. The primary and most frequent adverse effect of LFN exposure is annoyance. Moreover, some recent investigations showed that LFN at relatively low A-weighted sound pressure levels (40−45 dB) occurring in office-like areas could adversely affect the mental performance, especially of high-sensitive subjects. It is well documented that high-frequency noise disturbs various types of human functions; however, there is very little data on the impact of LFN on well-being and health, including the cardiovascular system. Heart rate variability (HRV) is a sensitive marker of autonomic regulation of the circulatory system. Walker and co-workers found that LFN has a significantly more negative impact on cardiovascular response than exposure to high-frequency noise and that changes in HRV parameters resulting from LFN exposure tend to persist over time. The negative reactions of the cardiovascular system in response to LFN generated by wind turbines (20-200 Hz) were confirmed by Chiu. The scientific aim of the study is to assess the relationship between the spectral-temporal characteristics of LFN and the activity of the autonomic nervous system, considering the subjective assessment of annoyance, sensitivity to this type of noise, and cognitive and general health status. The study will be conducted in 20 male students in a special, acoustically prepared, constantly supervised room. Each person will be tested 4 times (4 sessions), under conditions of non-exposure (sham) and exposure to noise of wind turbines recorded at a distance of 250 meters from the turbine with different frequencies and frequency ranges: acoustic band 20 Hz-20 kHz, infrasound band 5-20 Hz, acoustic band + infrasound band. The order of sessions of the experiment will be randomly selected. Each session will last 1 h. There will be a 2-3 days break between sessions to exclude the possibility of the earlier session influencing the results of the next one. Before the first exposure, a questionnaire will be conducted on noise sensitivity, general health status using the GHQ questionnaire, hearing organ status and sociodemographic data. Before each of the 4 exposures, subjects will complete a brief questionnaire on their mood and sleep quality the night before the test. After the test, the subjects will be asked about any discomfort and subjective symptoms during the exposure. Before the test begins, Holter ECG monitoring equipment will be installed. HRV will be analyzed from the ECG recordings, including time and frequency domain parameters. The tests will always be performed in the morning (9-12) to avoid the influence of diurnal rhythm on HRV results. Students will perform psychological tests 15 minutes before the end of the test (Vienna Test System). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurovegetative%20control" title="neurovegetative control">neurovegetative control</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate%20variability%20%28HRV%29" title=" heart rate variability (HRV)"> heart rate variability (HRV)</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20processes" title=" cognitive processes"> cognitive processes</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20frequency%20noise" title=" low frequency noise"> low frequency noise</a> </p> <a href="https://publications.waset.org/abstracts/174859/effect-of-noise-at-different-frequencies-on-heart-rate-variability-experimental-study-protocol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174859.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Evaluation of the Suitability of a Microcapsule-Based System for the Manufacturing of Self-Healing Low-Density Polyethylene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Golonka">Małgorzata Golonka</a>, <a href="https://publications.waset.org/abstracts/search?q=Jadwiga%20Laska"> Jadwiga Laska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among self-healing materials, the most unexplored group are thermoplastic polymers. These polymers are used not only to produce packaging with a relatively short life but also to obtain coatings, insulation, casings, or parts of machines and devices. Due to its exceptional resistance to weather conditions, hydrophobicity, sufficient mechanical strength, and ease of extrusion, polyethylene is used in the production of polymer pipelines and as an insulating layer for steel pipelines. Polyethylene or PE coated steel pipelines can be used in difficult conditions such as underground or underwater installations. Both installation and use under such conditions are associated with high stresses and consequently the formation of microdamages in the structure of the material, loss of its integrity and final applicability. The ideal solution would be to include a self-healing system in the polymer material. In the presented study the behavior of resin-coated microcapsules in the extrusion process of low-density polyethylene was examined. Microcapsules are a convenient element of the repair system because they can be filled with appropriate reactive substances to ensure the repair process, but the main problem is their durability under processing conditions. Rapeseed oil, which has a relatively high boiling point of 240⁰C and low volatility, was used as the core material that simulates the reactive agents. The capsule shell, which is a key element responsible for its mechanical strength, was obtained by in situ polymerising urea-formaldehyde, melamine-urea-formaldehyde or melamine-formaldehyde resin on the surface of oil droplets dispersed in water. The strength of the capsules was compared based on the shell material, and in addition, microcapsules with single- and multilayer shells were obtained using different combinations of the chemical composition of the resins. For example, the first layer of appropriate tightness and stiffness was made of melamine-urea-formaldehyde resin, and the second layer was a melamine-formaldehyde reinforcing layer. The size, shape, distribution of capsule diameters and shell thickness were determined using digital optical microscopy and electron microscopy. The efficiency of encapsulation (i.e., the presence of rapeseed oil as the core) and the tightness of the shell were determined by FTIR spectroscopic examination. The mechanical strength and distribution of microcapsules in polyethylene were tested by extruding samples of crushed low-density polyethylene mixed with microcapsules in a ratio of 1 and 2.5% by weight. The extrusion process was carried out in a mini extruder at a temperature of 150⁰C. The capsules obtained had a diameter range of 70-200 µm. FTIR analysis confirmed the presence of rapeseed oil in both single- and multilayer shell microcapsules. Microscopic observations of cross sections of the extrudates confirmed the presence of both intact and cracked microcapsules. However, the melamine-formaldehyde resin shells showed higher processing strength compared to that of the melamine-urea-formaldehyde coating and the urea-formaldehyde coating. Capsules with a urea-formaldehyde shell work very well in resin coating systems and cement composites, i.e., in pressureless processing and moulding conditions. The addition of another layer of melamine-formaldehyde coating to both the melamine-urea-formaldehyde and melamine-formaldehyde resin layers significantly increased the number of microcapsules undamaged during the extrusion process. The properties of multilayer coatings were also determined and compared with each other using computer modelling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-healing%20polymers" title="self-healing polymers">self-healing polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene" title=" polyethylene"> polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=microcapsules" title=" microcapsules"> microcapsules</a>, <a href="https://publications.waset.org/abstracts/search?q=extrusion" title=" extrusion"> extrusion</a> </p> <a href="https://publications.waset.org/abstracts/190298/evaluation-of-the-suitability-of-a-microcapsule-based-system-for-the-manufacturing-of-self-healing-low-density-polyethylene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190298.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">29</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Socio-Economic Determinants of Physical Activity of Non-Manual Workers, Including the Early Senior Group, from the City of Wroclaw in Poland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Puciato">Daniel Puciato</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Ole%C5%9Bniewicz"> Piotr Oleśniewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Julita%20Markiewicz-Patkowska"> Julita Markiewicz-Patkowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Widawski"> Krzysztof Widawski</a>, <a href="https://publications.waset.org/abstracts/search?q=Micha%C5%82%20Rozpara"> Michał Rozpara</a>, <a href="https://publications.waset.org/abstracts/search?q=W%C5%82adys%C5%82aw%20Mynarski"> Władysław Mynarski</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Gawlik"> Agnieszka Gawlik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20D%C4%99bska"> Małgorzata Dębska</a>, <a href="https://publications.waset.org/abstracts/search?q=So%C5%88a%20Jandov%C3%A1"> Soňa Jandová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Physical activity as a part of people’s everyday life reduces the risk of many diseases, including those induced by lifestyle, e.g. obesity, type 2 diabetes, osteoporosis, coronary heart disease, degenerative arthritis, and certain types of cancer. That refers particularly to professionally active people, including the early senior group working on non-manual positions. The aim of the study is to evaluate the relationship between physical activity and the socio-economic status of non-manual workers from Wroclaw—one of the biggest cities in Poland, a model setting for such investigations in this part of Europe. The crucial problem in the research is to find out the percentage of respondents who meet the health-related recommendations of the World Health Organization (WHO) concerning the volume, frequency, and intensity of physical activity, as well as to establish if the most important socio-economic factors, such as gender, age, education, marital status, per capita income, savings and debt, determine the compliance with the WHO physical activity recommendations. During the research, conducted in 2013, 1,170 people (611 women and 559 men) aged 21–60 years were examined. A diagnostic poll method was applied to collect the data. Physical activity was measured with the use of the short form of the International Physical Activity Questionnaire with extended socio-demographic questions, i.e. concerning gender, age, education, marital status, income, savings or debts. To evaluate the relationship between physical activity and selected socio-economic factors, logistic regression was used (odds ratio statistics). Statistical inference was conducted on the adopted ex ante probability level of p<0.05. The majority of respondents met the volume of physical effort recommended for health benefits. It was particularly noticeable in the case of the examined men. The probability of compliance with the WHO physical activity recommendations was highest for workers aged 21–30 years with secondary or higher education who were single, received highest incomes and had savings. The results indicate the relations between physical activity and socio-economic status in the examined women and men. People with lower socio-economic status (e.g. manual workers) are physically active primarily at work, whereas those better educated and wealthier implement physical effort primarily in their leisure time. Among the investigated subjects, the youngest group of non-manual workers have the best chances to meet the WHO standards of physical activity. The study also confirms that secondary education has a positive effect on the public awareness on the role of physical activity in human life. In general, the analysis of the research indicates that there is a relationship between physical activity and some socio-economic factors of the respondents, such as gender, age, education, marital status, income per capita, and the possession of savings. Although the obtained results cannot be applied for the general population, they show some important trends that will be verified in subsequent studies conducted by the authors of the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IPAQ" title="IPAQ">IPAQ</a>, <a href="https://publications.waset.org/abstracts/search?q=nonmanual%20workers" title=" nonmanual workers"> nonmanual workers</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=socioeconomic%20factors" title=" socioeconomic factors"> socioeconomic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=WHO" title=" WHO"> WHO</a> </p> <a href="https://publications.waset.org/abstracts/52092/socio-economic-determinants-of-physical-activity-of-non-manual-workers-including-the-early-senior-group-from-the-city-of-wroclaw-in-poland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52092.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">535</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Conceptual Design of a Residential House Based on IDEA 4E - Discussion of the Process of Interdisciplinary Pre-Project Research and Optimal Design Solutions Created as Part of Project-Based Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dorota%20Winnicka-Jas%C5%82owska">Dorota Winnicka-Jasłowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Ma%C5%82gorzata%20Jastrz%C4%99bska"> Małgorzata Jastrzębska</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Kaczmarczyk"> Jan Kaczmarczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Beata%20%C5%81a%C5%BAniewska-Piekarczyk"> Beata Łaźniewska-Piekarczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Sk%C3%B3ra"> Piotr Skóra</a>, <a href="https://publications.waset.org/abstracts/search?q=Beata%20Kobia%C5%82ko"> Beata Kobiałko</a>, <a href="https://publications.waset.org/abstracts/search?q=Agata%20Ko%C5%82odziej"> Agata Kołodziej</a>, <a href="https://publications.waset.org/abstracts/search?q=B%C5%82a%C5%BCej%20M%C3%B3l"> Błażej Mól</a>, <a href="https://publications.waset.org/abstracts/search?q=Ewelina%20Lasyk"> Ewelina Lasyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Karolina%20Brz%C4%99czek"> Karolina Brzęczek</a>, <a href="https://publications.waset.org/abstracts/search?q=Micha%C5%82%20Kr%C3%B3l"> Michał Król</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Creating economical, comfortable, and healthy buildings which respect the environment is a necessity resulting from legal regulations, but it is also a response to the expectations of a modern investor. Developing the concept of a residential house based on the 4E and the 2+2+(1) IDEAs is a complex process that requires specialist knowledge of many trades and requires adaptation of comprehensive solutions. IDEA 4E assumes the use of energy-saving, ecological, ergonomics, and economic solutions. In addition, IDEA 2+2+(1) assuming appropriate surface and functional-spatial solutions for a family at different stages of a building's life, i.e. 2, 4, or 5 members, enforces certain flexibility of the designed building, which may change with the number and age of its users. The building should therefore be easy to rearrange or expand. The task defined in this way was carried out by an interdisciplinary team of students of the Silesian University of Technology as part of PBL. The team consisted of 6 undergraduate and graduate students representing the following faculties: 3 students of architecture, 2 civil engineering students, and 1 student of environmental engineering. The work of the team was supported by 3 academic teachers representing the above-mentioned faculties and additional experts. The project was completed in one semester. The article presents the successive stages of the project. At first pre-design studies were carried out. They allowed to define the guidelines for the project. For this purpose, the "Model house" questionnaire was developed. The questions concerned determining the utility needs of a potential family that would live in a model house - specifying the types of rooms, their size, and equipment. A total of 114 people participated in the study. The answers to the questions in the survey helped to build the functional programme of the designed house. Other research consisted in the search for optimal technological and construction solutions and the most appropriate building materials based mainly on recycling. Appropriate HVAC systems responsible for the building's microclimate were also selected, i.e. low, temperature heating, mechanical ventilation, and the use of energy from renewable sources was planned so as to obtain a nearly zero-energy building. Additionally, rainwater retention and its local use were planned. The result of the project was a design of a model residential building that meets the presented assumptions. A 3D VR spatial model of the designed building and its surroundings was also made. The final result was the organization of an exhibition for students and the academic community. Participation in the interdisciplinary project allowed the project team members to better understand the consequences of the adopted solutions for achieving the assumed effect and the need to work out a compromise. The implementation of the project made all its participants aware of the importance of cooperation as well as systematic and clear communication. The need to define milestones and their consistent enforcement is an important element guaranteeing the achievement of the intended end result. The implementation of PBL enables students to the acquire competences important in their future professional work. <p class="card-text"><strong>Keywords:</strong> <a
