of asthma–COPD overlap syndrome (ACOS) are controversial in pediatrics. Emphysema is characteristic of COPD and usually does not occur in typical asthma; its presence in patients with asthma suggests the concurrence with COPD. Low-dose chest computed tomography (CT) allows a non-invasive assessment of the lung tissue structure. Here we present CT findings of emphysematous changes in a child with ACOS. Patient and Methods: In a 6-year-old boy, atopy was confirmed by a skin prick test using common allergen extracts (grass and tree pollen, house dust mite, molds, cat, dog; manufacturer Stallergenes Greer, London, UK), where reactions over 3 mm were considered positive. Treatment with corticosteroids was started during the course of severe asthma. At 12 years of age, his spirometric parameters deteriorated despite treatment adjustment (VC 1.76 L=85%, FEV1 1.13 L=67%, TI%VCmax 64%, MEF25 19%, TLC 144%) and the bronchodilator test became negative. Results: Low-dose chest CT displayed irregular regions with increased radiolucency of pulmonary parenchyma (typical for hyperinflation in emphysematous changes) in both lungs. This was in accordance with the results of spirometric examination. Conclusions: ACOS is infrequent in children. However, low-dose chest CT scan can be considered to confirm this diagnosis or eliminate other diagnoses when the clinical condition is deteriorating and treatment response is poor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=child" title="child">child</a>, <a href="https://publications.waset.org/abstracts/search?q=asthma" title=" asthma"> asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=low-dose%20chest%20CT" title=" low-dose chest CT"> low-dose chest CT</a>, <a href="https://publications.waset.org/abstracts/search?q=ACOS" title=" ACOS"> ACOS</a> </p> <a href="https://publications.waset.org/abstracts/102811/low-dose-chest-computed-tomography-can-help-in-differential-diagnosis-of-asthma-copd-overlap-syndrome-in-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102811.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">146</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> Web Application for Evaluating Tests in Distance Learning Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bogdan%20Walek">Bogdan Walek</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Bradac"> Vladimir Bradac</a>, <a href="https://publications.waset.org/abstracts/search?q=Radim%20Farana"> Radim Farana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Distance learning systems offer useful methods of learning and usually contain final course test or another form of test.

Test results and forecasts translate directly into the education system in this country, which is largely a state system. Sweden is one of the first countries in Europe that has used active labor market policies. It is realized that there is an active unemployment which includes a wide range of activities that can be divided into three groups: Active forms of influencing the creation of new jobs, active forms that affect the labor supply and active forms for people with disabilities. Most of the funding is allocated there for subsidized employment and training. Research conducted in Sweden shows that active forms of counteracting unemployment focused on the long-term unemployed can significantly raise the level of employment in this group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sweden" title="Sweden">Sweden</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20conducted%20in%20Sweden" title=" research conducted in Sweden"> research conducted in Sweden</a>, <a href="https://publications.waset.org/abstracts/search?q=labour%20market" title=" labour market"> labour market</a>, <a href="https://publications.waset.org/abstracts/search?q=labour%20market%20policies" title=" labour market policies"> labour market policies</a>, <a href="https://publications.waset.org/abstracts/search?q=unemployment" title=" unemployment"> unemployment</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20forms%20of%20influencing%20the%20creation%20of%20new%20jobs" title=" active forms of influencing the creation of new jobs"> active forms of influencing the creation of new jobs</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20forms%20of%20counteracting%20unemployment" title=" active forms of counteracting unemployment"> active forms of counteracting unemployment</a>, <a href="https://publications.waset.org/abstracts/search?q=employment" title=" employment"> employment</a>, <a href="https://publications.waset.org/abstracts/search?q=subsidized%20employment%20education" title=" subsidized employment education"> subsidized employment education</a> </p> <a href="https://publications.waset.org/abstracts/68495/combating-and-preventing-unemployment-in-sweden" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68495.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">289</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> Advantages of Fuzzy Control Application in Fast and Sensitive Technological Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radim%20Farana">Radim Farana</a>, <a href="https://publications.waset.org/abstracts/search?q=Bogdan%20Walek"> Bogdan Walek</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Janosek"> Michal Janosek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Zacek"> Jaroslav Zacek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the advantages of fuzzy control use in technological processes control. The paper presents a real application of the Linguistic Fuzzy-Logic Control, developed at the University of Ostrava for the control of physical models in the Intelligent Systems Laboratory. The paper presents an example of a sensitive non-linear model, such as a magnetic levitation model and obtained results which show how modern information technologies can help to solve actual technical problems. A special method based on the LFLC controller with partial components is presented in this paper followed by the method of automatic context change, which is very helpful to achieve more accurate control results. The main advantage of the used system is its robustness in changing conditions demonstrated by comparing with conventional PID controller. This technology and real models are also used as a background for problem-oriented teaching, realized at the department for master students and their collaborative as well as individual final projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control" title="control">control</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitive%20system" title=" sensitive system"> sensitive system</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20proves" title=" technological proves"> technological proves</a> </p> <a href="https://publications.waset.org/abstracts/36948/advantages-of-fuzzy-control-application-in-fast-and-sensitive-technological-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36948.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">469</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 Impact of Bequest Taxation on Human Capital Accumulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maciej%20Dudek">Maciej Dudek</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Kruszewski"> Robert Kruszewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Janusz%20Kudla"> Janusz Kudla</a>, <a href="https://publications.waset.org/abstracts/search?q=Konrad%20Walczyk"> Konrad Walczyk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study how taxation of bequests affects human capital formation in the long term and short term horizon. Our underlying model is an overlapping generation model (OLG) with some degree of altruism on the part of the ancestors' generation towards their descendants. We ask the question in three separate frameworks. First, we study a simple one-sector model where a proxy of human capital is wage income. It the steady-state -for CRRA utility function and human capital produced with non-decreasing returns -the taxation of bequests is neutral to the accumulation of human capital. In the second framework, neutrality applies to the growth rates of human capital, physical capital, and consumption. In this case, taxation increases the level of bequests, leading to a lower value of current consumption. Finally in we consider two periods model instead of infinite horizon model as long as the tax revenue is at least partially rebated back to the public, the fraction of human capital engaged in the process of formation of human capital increases with the tax rate on bequests. In other words, taxation of bequests is partially offset by an increase in human capital formation. Higher human capital allows the future generation to earn higher wages, and today's generation can find it optimal to endow the future generation with more human capital when taxation is imposed on physical capital transferred to the next generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=taxation" title="taxation">taxation</a>, <a href="https://publications.waset.org/abstracts/search?q=bequests" title=" bequests"> bequests</a>, <a href="https://publications.waset.org/abstracts/search?q=policy" title=" policy"> policy</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20capital" title=" human capital"> human capital</a> </p> <a href="https://publications.waset.org/abstracts/122668/the-impact-of-bequest-taxation-on-human-capital-accumulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122668.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">8</span> The Effects of Stand Density, Standards and Species Composition on Biomass Production in Traditional Coppices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marek%20Mejst%C5%99%C3%ADk">Marek Mejstřík</a>, <a href="https://publications.waset.org/abstracts/search?q=Radim%20Matula"> Radim Matula</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20%C5%A0r%C3%A1mek"> Martin Šrámek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional coppices and coppice-with-standards were widely used throughout Europe and Asia for centuries but were largely abandoned in the second half of the 19th century, especially in central and northwestern Europe. In the last decades, there has been a renewed interest in traditional coppicing for nature conservation and most often, for rapid woody biomass production. However, there is little information on biomass productivity of traditional coppices and what affects it. Here, we focused on the effects of stand density, standards and tree species composition on sprout biomass production in newly restored coppices in the Czech Republic. We measured sprouts and calculated sprout biomass 7 years after the harvest from 2013 resprouting stumps in two 4 ha experimental plots. Each plot was divided into 64 subplots with different densities of standards and sprouting stumps. Total sprout biomass declined with increasing density of standards, but the effect of standards differed significantly among studied species. Whereas increasing density of standards decreased sprout biomass in Quercus petraea and Carpinus betulus, it did not affect sprout biomass productivity in Acer campestre and Tilia cordata. Sprout biomass on stand-level increased linearly with an increasing number of sprouting stumps and we observed no leveling of this relationship even in the highest densities of stumps. We also found a significant shift in tree species composition with the steeply declining relative abundance of Quercus in favor of other studied tree species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traditional%20coppice" title="traditional coppice">traditional coppice</a>, <a href="https://publications.waset.org/abstracts/search?q=coppice%20with%20standards" title=" coppice with standards"> coppice with standards</a>, <a href="https://publications.waset.org/abstracts/search?q=sprout%20biomass" title=" sprout biomass"> sprout biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20management" title=" forest management"> forest management</a> </p> <a href="https://publications.waset.org/abstracts/147514/the-effects-of-stand-density-standards-and-species-composition-on-biomass-production-in-traditional-coppices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147514.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">160</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> Anatomy of the Human Mitral Valve Leaflets: Implications for Transcatheter and Surgical Mitral Valve Repair Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agata%20Krawczyk-Ozog">Agata Krawczyk-Ozog</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20K.%20Holda"> Mateusz K.

The aim of this study was to characterize morphological variability of the mitral valve leaflets and to provide the size of their particular parts. Materials and Methods: In the study, we included 200 autopsied human hearts from Caucasian individuals (25% females) with mean age 47.5 (±17.9) without any valvular diseases. The morphology of the mitral valve was evaluated. The intercommissural and aorto-mural diameters of the mitral annulus were measured. All leaflets and their scallops were identified. The base and the height of the posteromedial commissure (PM-C), anterolateral commissure (AL-C), anterior leaflet (AL) and posterior leaflet (PL) with their scallops were measured. Results: The intercommissural diameter was 28.0±4.8 mm, the aorto-mural diameter 19.7±4.8 mm, circumference of the mitral annulus 89.9±12.6 mm and the area of the mitral valve 485.4±171.4 mm2. Classical mitral valves (AL+AL-C+PL(P1,P2,P3)+PM-C) were found in 141 (70.5%) specimens. In classical type, the mean AL base and height were 30.8±4.9 mm and 20.6±4.2 mm, while mean PL base and height 45.1±8.2 mm 12.9±2.8 mm respectively. The mean ratio of the AL base to PL base was 0.7±0.2. Variations in PL were found in 55 (27.5%) and in AL in 5 (2.5%) hearts. The most common variations were: valve with one accessory scallop (AcS) between P3 and PM-C (7%); AcS between P1 and AL-C (4%); connections of P2 and P3 scallops (4%); connections of P1 and P2 scallops (3%); AcS in AL (2.5%). All AcS were smaller than the main PL scallops. The mean intertrigonal distance was 21.9±3.8 mm. Conclusions: In all cases, the mitral valve is built by two main leaflets with possible variants in secondary to leaflets scallops (29.5%). The variations are largely associated with PL and are mostly related to the presence of AcS. Anatomically the AL is not divided into scallops, and it occupies 34.5% of the mitral annulus circumference. Understanding the anatomy of the mitral valve leaflets helps to planning and performing mitral valve repair procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessory%20scallop" title="accessory scallop">accessory scallop</a>, <a href="https://publications.waset.org/abstracts/search?q=commissure" title=" commissure"> commissure</a>, <a href="https://publications.waset.org/abstracts/search?q=connected%20%20scallops" title=" connected scallops"> connected scallops</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20heart" title=" human heart"> human heart</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20leaflets" title=" mitral leaflets"> mitral leaflets</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20valve" title=" mitral valve"> mitral valve</a> </p> <a href="https://publications.waset.org/abstracts/65755/anatomy-of-the-human-mitral-valve-leaflets-implications-for-transcatheter-and-surgical-mitral-valve-repair-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65755.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">389</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> Constructivism and Situational Analysis as Background for Researching Complex Phenomena: Example of Inclusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radim%20Sip">Radim Sip</a>, <a href="https://publications.waset.org/abstracts/search?q=Denisa%20Denglerova"> Denisa Denglerova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It’s impossible to capture complex phenomena, such as inclusion, with reductionism. The most common form of reductionism is the objectivist approach, where processes and relationships are reduced to entities and clearly outlined phases, with a consequent search for relationships between them. Constructivism as a paradigm and situational analysis as a methodological research portfolio represent a way to avoid the dominant objectivist approach. They work with a situation, i.e. with the essential blending of actors and their environment. Primary transactions are taking place between actors and their surroundings. Researchers create constructs based on their need to solve a problem. Concepts therefore do not describe reality, but rather a complex of real needs in relation to the available options how such needs can be met. For examination of a complex problem, corresponding methodological tools and overall design of the research are necessary. Using an original research on inclusion in the Czech Republic as an example, this contribution demonstrates that inclusion is not a substance easily described, but rather a relationship field changing its forms in response to its actors’ behaviour and current circumstances. Inclusion consists of dynamic relationship between an ideal, real circumstances and ways to achieve such ideal under the given circumstances. Such achievement has many shapes and thus cannot be captured by description of objects. It can be expressed in relationships in the situation defined by time and space. Situational analysis offers tools to examine such phenomena. It understands a situation as a complex of dynamically changing aspects and prefers relationships and positions in the given situation over a clear and final definition of actors, entities, etc. Situational analysis assumes creation of constructs as a tool for solving a problem at hand. It emphasizes the meanings that arise in the process of coordinating human actions, and the discourses through which these meanings are negotiated. Finally, it offers “cartographic tools” (situational maps, socials worlds / arenas maps, positional maps) that are able to capture the complexity in other than linear-analytical ways. This approach allows for inclusion to be described as a complex of phenomena taking place with a certain historical preference, a complex that can be overlooked if analyzed with a more traditional approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructivism" title="constructivism">constructivism</a>, <a href="https://publications.waset.org/abstracts/search?q=situational%20analysis" title=" situational analysis"> situational analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=objective%20realism" title=" objective realism"> objective realism</a>, <a href="https://publications.waset.org/abstracts/search?q=reductionism" title=" reductionism"> reductionism</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a> </p> <a href="https://publications.waset.org/abstracts/135156/constructivism-and-situational-analysis-as-background-for-researching-complex-phenomena-example-of-inclusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135156.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">149</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> Change of Taste Preference after Bariatric Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Tylec">Piotr Tylec</a>, <a href="https://publications.waset.org/abstracts/search?q=Julia%20Wierzbicka"> Julia Wierzbicka</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Gajewska"> Natalia Gajewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Przeczek"> Krzysztof Przeczek</a>, <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Torbicz"> Grzegorz Torbicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicja%20Dudek"> Alicja Dudek</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Pisarska-Adamczyk"> Magdalena Pisarska-Adamczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Wierdak"> Mateusz Wierdak</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Pedziwiatr"> Michal Pedziwiatr </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Many patients have described changes in taste perception after weight loss surgery. However, little data is available about short term changes in taste after surgery. Aim: We aimed to evaluate short-term changes in taste preference after bariatric surgeries in comparison to colorectal surgeries. Material and Methods: Between April 2018 and April 2019, a total of 121 bariatric patients and 63 controls participated. Bariatric patients underwent laparoscopic sleeve gastrectomy or Roux-en-Y gastric by-pass. Controls underwent oncological colorectal surgeries. Patients who developed clinical complications requiring restriction of oral intake after surgery or withdraw their consent were excluded from the study. In the end, 85 bariatric patients and 44 controls were included. In all of them, the 16-item ERAS Protocol was applied. Using 10-points Numeric Rating Scale (1-10) patients completed questionnaire and rated their appetite and thirst (1 - no appetite/not thirsty, 10 – normal appetite/very thirsty) and flavoured standardized liquids' taste (1- horrible, 10-very tasty) and food images for the 6 group of taste (sweet, umami, sour, spicy, bitter and salty) (1 - not appetizing, 10 - very appetizing) preoperatively and on the first postoperative day. Data were analysed with Statistica 13.0 PL. Results: Analysed group consist of 129 patients (85 bariatric, 44 controls). Mean age and BMI in a research group was 44.91 years old, 46.22 kg/m² and in control group 62.09 years old, 25.87 kg/m², respectively. Our analysis revealed significant differences in changes of appetite between both groups (research: -4.55 ± 3.76 vs. control: -0.85 ± 4.37; p < 0.05), ratings bitter (research: 0.60 ± 2.98 vs. control: -0.88 ± 2.58; p < 0.05) and salty (research: 1.20 ± 3.50 vs. control: -0.52 ± 2.90; p < 0.05) flavoured liquids and ratings for sweet (research: 1.62 ± 3.31 vs. control: 0.01 ± 2.63; p < 0.05) and bitter (research: 1.21 ± 3.15 vs. control: -0.09 ± 2.25; p < 0.05) food images. There were statistically significant results in the ratings of other images, but in comparison to the control group, they were not statistically significant. Conclusion: The study showed that bariatric surgeries quickly decreases appetite and desire to eat certain types of food, such as salty. Moreover, the bitter taste was more desirable in the research group in comparison to control group. Nevertheless, the sweet taste was more appetible in the bariatric group than in control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bariatric%20surgery" title="bariatric surgery">bariatric surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=general%20surgery" title=" general surgery"> general surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=taste%20preference" title=" taste preference"> taste preference</a> </p> <a href="https://publications.waset.org/abstracts/128223/change-of-taste-preference-after-bariatric-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128223.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">135</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> Journey to Inclusive School: Description of Crucial Sensitive Concepts in the Context of Situational Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denisa%20Denglerova">Denisa Denglerova</a>, <a href="https://publications.waset.org/abstracts/search?q=Radim%20Sip"> Radim Sip</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Academic sources as well as international agreements and national documents define inclusion in terms of several criteria: equal opportunities, fulfilling individual needs, development of human resources, community participation. In order for these criteria to be met, the community must be cohesive. Community cohesion, which is a relatively new concept, is not determined by homogeneity, but by the acceptance of diversity among the community members and utilisation of its positive potential. This brings us to a central category of inclusion - appreciating diversity and using it to a positive effect. However, school diversity is a real phenomenon, which schools need to tackle more and more often. This is also indicated by the number of publications focused on diversity in schools. These sources present recent analyses of using identity as a tool of coping with the demands of a diversified society. The aim of this study is to identify and describe in detail the processes taking place in selected schools, which contribute to their pro-inclusive character. The research is designed around a multiple case study of three pro-inclusive schools. Paradigmatically speaking, the research is rooted in situational epistemology. This is also related to the overall framework of interpretation, for which we are going to use innovative methods of situational analysis. In terms of specific research outcomes this will manifest itself in replacing the idea of “objective theory” by the idea of “detailed cartography of a social world”. The cartographic approach directs both the logic of data collection and the choice of methods of their analysis and interpretation. The research results include detection of the following sensitive concepts: Key persons. All participants can contribute to promoting an inclusion-friendly environment; however, some do so with greater motivation than others. These could include school management, teachers with a strong vision of equality, or school counsellors. They have a significant effect on the transformation of the school, and are themselves deeply convinced that inclusion is necessary. Accordingly, they select suitable co-workers; they also inspire some of the other co-workers to make changes, leading by example. Employees with strongly opposing views gradually leave the school, and new members of staff are introduced to the concept of inclusion and openness from the beginning. Manifestations of school openness in working with diversity on all important levels. By this we mean positive manipulation with diversity both in the relationships between “traditional” school participants (directors, teachers, pupils) and school-parent relationships, or relationships between schools and the broader community, in terms of teaching methods as well as ways how the school culture affects the school environment. Other important detected concepts significantly helping to form a pro-inclusive environment in the school are individual and parallel classes; freedom and responsibility of both pupils and teachers, manifested on the didactic level by tendencies towards an open curriculum; ways of asserting discipline in the school environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inclusion" title="inclusion">inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitive%20concept" title=" sensitive concept"> sensitive concept</a>, <a href="https://publications.waset.org/abstracts/search?q=situational%20analysis" title=" situational analysis"> situational analysis</a> </p> <a href="https://publications.waset.org/abstracts/135150/journey-to-inclusive-school-description-of-crucial-sensitive-concepts-in-the-context-of-situational-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135150.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">198</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> Comparison of Quality of Life One Year after Bariatric Intervention: Systematic Review of the Literature with Bayesian Network Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Tylec">Piotr Tylec</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicja%20Dudek"> Alicja Dudek</a>, <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Torbicz"> Grzegorz Torbicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Mizera"> Magdalena Mizera</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalia%20Gajewska"> Natalia Gajewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Su"> Michael Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanawat%20Vongsurbchart"> Tanawat Vongsurbchart</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomasz%20Stefura"> Tomasz Stefura</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Pisarska"> Magdalena Pisarska</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Rubinkiewicz"> Mateusz Rubinkiewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Malczak"> Piotr Malczak</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Major"> Piotr Major</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Pedziwiatr"> Michal Pedziwiatr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Quality of life after bariatric surgery is an important factor when evaluating the final result of the treatment. Considering the vast surgical options, we tried to globally compare available methods in terms of quality of following the surgery. The aim of the study is to compare the quality of life a year after bariatric intervention using network meta-analysis methods. Material and Methods: We performed a systematic review according to PRISMA guidelines with Bayesian network meta-analysis. Inclusion criteria were: studies comparing at least two methods of weight loss treatment of which at least one is surgical, assessment of the quality of life one year after surgery by validated questionnaires. Primary outcomes were quality of life one year after bariatric procedure. The following aspects of quality of life were analyzed: physical, emotional, general health, vitality, role physical, social, mental, and bodily pain. All questionnaires were standardized and pooled to a single scale. Lifestyle intervention was considered as a referenced point. Results: An initial reference search yielded 5636 articles. 18 studies were evaluated. In comparison of total score of quality of life, we observed that laparoscopic sleeve gastrectomy (LSG) (median (M): 3.606, Credible Interval 97.5% (CrI): 1.039; 6.191), laparoscopic Roux en-Y gastric by-pass (LRYGB) (M: 4.973, CrI: 2.627; 7.317) and open Roux en-Y gastric by-pass (RYGB) (M: 9.735, CrI: 6.708; 12.760) had better results than other bariatric intervention in relation to lifestyle interventions. In the analysis of the physical aspects of quality of life, we notice better results in LSG (M: 3.348, CrI: 0.548; 6.147) and in LRYGB procedure (M: 5.070, CrI: 2.896; 7.208) than control intervention, and worst results in open RYGB (M: -9.212, CrI: -11.610; -6.844). Analyzing emotional aspects, we found better results than control intervention in LSG, in LRYGB, in open RYGB, and laparoscopic gastric plication. In general health better results were in LSG (M: 9.144, CrI: 4.704; 13.470), in LRYGB (M: 6.451, CrI: 10.240; 13.830) and in single-anastomosis gastric by-pass (M: 8.671, CrI: 1.986; 15.310), and worst results in open RYGB (M: -4.048, CrI: -7.984; -0.305). In social and vital aspects of quality of life, better results were observed in LSG and LRYGB than control intervention. We did not find any differences between bariatric interventions in physical role, mental and bodily aspects of quality of life. Conclusion: The network meta-analysis revealed that better quality of life in total score one year after bariatric interventions were after LSG, LRYGB, open RYGB. In physical and general health aspects worst quality of life was in open RYGB procedure. Other interventions did not significantly affect the quality of life after a year compared to dietary intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bariatric%20surgery" title="bariatric surgery">bariatric surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20meta-analysis" title=" network meta-analysis"> network meta-analysis</a>, <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=one%20year%20follow-up" title=" one year follow-up"> one year follow-up</a> </p> <a href="https://publications.waset.org/abstracts/128224/comparison-of-quality-of-life-one-year-after-bariatric-intervention-systematic-review-of-the-literature-with-bayesian-network-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128224.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">159</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> Design of a Mhealth Therapy Management to Maintain Therapy Outcomes after Bariatric Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Dudek">A.

Long-term maintenance of a proper metabolic results after rapid weight loss due to bariatric surgery requires engagement from patients. Mobile health tool may offer alternative model that enhance participant engagement in keeping the therapy. Objective: We aimed to assess the influence of constant monitoring and subsequent motivational alerts in perioperative period and on post-operative effects in the bariatric patients. As well as the study was designed to identify factors conductive urge to change lifestyle after surgery. Methods: This prospective clinical control study was based on a usage of a designed prototype of bariatric mHealth system. The prepared application comprises central data management with a comprehensible interface dedicated for patients and data transfer module as a physician’s platform. Motivation system of a platform consist of motivational alerts, graphic outcome presentation, and patient communication center. Generated list of patients requiring urgent consultation and possibility of a constant contact with a specialist provide safety zone. 31 patients were enrolled in continuous monitoring program during a 6-month period along with typical follow-up visits. After one year follow-up, all patients were examined. Results: There were 20 active users of the proposed monitoring system during the entire duration of the study. After six months, 24 patients took a part in a control by telephone questionnaires. Among them, 75% confirmed that the application concept was an important element in the treatment. Active users of the application indicated as the most valuable features: motivation to continue treatment (11 users), graphical presentation of weight loss, and other parameters (7 users), the ability to contact a doctor (3 users). The three main drawbacks are technical errors (9 users), tedious questionnaires inside the application (5 users), and time-consuming tasks inside the system (2 users). Conclusions: Constant monitoring and successive motivational alerts to continue treatment is an appropriate tool in the treatment after bariatric surgery, mainly in the early post-operative period. Graphic presentation of data and continuous connection with a clinical staff seemed to be an element of motivation to continue treatment and a sense of security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bariatric%20surgery" title="bariatric surgery">bariatric surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=mHealth" title=" mHealth"> mHealth</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20health%20tool" title=" mobile health tool"> mobile health tool</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/128225/design-of-a-mhealth-therapy-management-to-maintain-therapy-outcomes-after-bariatric-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128225.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">113</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> Influence of Disintegration of Sida hermaphrodita Silage on Methane Fermentation Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Zielinski">Marcin Zielinski</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcin%20Debowski"> Marcin Debowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulina%20Rusanowska"> Paulina Rusanowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Magda%20Dudek"> Magda Dudek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a result of sonification, the destruction of complex biomass structures results in an increase in the biogas yield from the conditioned material. First, the amount of organic matter released into the solution due to disintegration was determined. This parameter was determined by changes in the carbon content in liquid phase of the conditioned substrate. The amount of carbon in the liquid phase increased with the prolongation of the sonication time to 16 min. Further increase in the duration of sonication did not cause a statistically significant increase in the amount of organic carbon in the liquid phase. The disintegrated material was then used for respirometric measurements for determination of the impact of the conditioning process used on methane fermentation effectiveness. The relationship between the amount of energy introduced into the lignocellulosic substrate and the amount of biogas produced has been demonstrated. Statistically significant increase in the amount of biogas was observed until sonication of 16 min. Further increase in energy in the conditioning process did not significantly increase the production of biogas from the treated substrate. The biogas production from the conditioned substrate was 17% higher than from the reference biomass at that time. The ultrasonic disintegration method did not significantly affect the observed biogas composition. In all series, the methane content in the produced biogas from the conditioned substrate was similar to that obtained with the raw substrate sample (51.1%). Another method of substrate conditioning was hydrothermal depolymerization. This method consists in application of increased temperature and pressure to substrate. These phenomena destroy the structure of the processed material, the release of organic compounds to the solution, which should lead to increase the amount of produced biogas from such treated biomass. The hydrothermal depolymerization was conducted using an innovative microwave heating method. Control measurements were performed using conventional heating. The obtained results indicate the relationship between depolymerization temperature and the amount of biogas. Statistically significant value of the biogas production coefficients increased as the depolymerization temperature increased to 150°C. Further raising the depolymerization temperature to 180°C did not significantly increase the amount of produced biogas in the respirometric tests. As a result of the hydrothermal depolymerization obtained using microwave at 150°C for 20 min, the rate of biogas production from the Sida silage was 780 L/kg VS, which accounted for nearly 50% increase compared to 370 L/kg VS obtained from the same silage but not depolymerised. The study showed that by microwave heating it is possible to effectively depolymerized substrate. Significant differences occurred especially in the temperature range of 130-150ºC. The pre-treatment of Sida hermaphrodita silage (biogas substrate) did not significantly affect the quality of the biogas produced. The methane concentration was about 51.5% on average. The study was carried out in the framework of the project under program BIOSTRATEG funded by the National Centre for Research and Development No. 1/270745/2/NCBR/2015 'Dietary, power, and economic potential of Sida hermaphrodita cultivation on fallow land'. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disintegration"
