Objective: To determine how group education about early diagnostic methods for breast and cervical cancer affects women’s behavior and readiness to receive mammography and Pap smears. Methods: This semi-interventional study was conducted at a textile factory in Istanbul, Turkey. Female workers (n = 125) were included in the study. A participant identification form and knowledge evaluation form developed for this study, along with the trans-theoretical model, were used to collect data. A 45-min interactive group education was given to the participants. Results: Upon contacting participants 3 months after group education, 15.4% (n = 11) stated that they had since received a mammogram and 9.8% (n = 7) a Pap smear. As suggested by the trans-theoretical model, group education increased participants’ readiness to receive cancer screening, along with their knowledge of breast and cervical cancer. Conclusions: Group education positively impacted women’s knowledge of cancer and their readiness to receive mammography and Pap smears. Group education can therefore potentially create awareness of cancer screening tests among women and improve their readiness to receive such tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20screening" title="cancer screening">cancer screening</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20intervention" title=" educational intervention"> educational intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=participation" title=" participation"> participation</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women "> women </a> </p> <a href="https://publications.waset.org/abstracts/16775/how-group-education-impacts-female-factory-workers-behavior-and-readiness-to-receive-mammography-and-pap-smears" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16775.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">329</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> Biology of Salema (Sarpa Salpa (L.)) and Population off Gökceada (Northern Aegean Sea, Türkiye): A Macro herbivore Species Living in Sea Grass Beds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeliha%20Erdogan">Zeliha Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatice%20Torcu%20Koc"> Hatice Torcu Koc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fish, Sarpa salpa (L.), is one of the main macroherbivores in the Mediterranean. A total of 600 Salema individuals were collected from around Gökçeada, Sea of Northern Aegean, between January 2014 and January 2015 in order to evaluate some information on the biology of the Salema population. For this aim, measurements of the Salema were obtained using a caliper. The age readings were made from otoliths. The population was composed of 6 age classes (I-VI). The total lengths and total weights of sampled fish were determined to be ranged from 12.5 to 33.1 cm and 33.57 to 559.33 g, respectively. Length-weight relationship for all individuals was calculated as W=0.0085*L3.1723, R2=0.9524. Growth parameters were determined as L∞= 35.55cm, k=0.31, t0= -9.2, '=2.60. As the sexual ratio was 1.08:1 (M: F), the Salema population consisted of 51.66% male and 47.5% female individuals. The highest average condition factors were observed for females in May (1.68) and for males in May (1.67). According to gonad somatic index values, the spawning period was determined twice a year in spring (April) and autumn (October). The highest average hepatosomatix index value was observed for all individuals in May and December. It was estimated that total (Z) mortality, natural (M) mortality, and fishing (F) mortality rates were Z=0.44 year-1, M=0.064 year-1 and F=0.38 year-1, respectively. As the exploitation rate was estimated as E=0.86, it can be shown that the Salema stock was highly influenced by overfishing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biology" title="biology">biology</a>, <a href="https://publications.waset.org/abstracts/search?q=sarpa%20salpa" title=" sarpa salpa"> sarpa salpa</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6kceada" title=" Gökceada"> Gökceada</a>, <a href="https://publications.waset.org/abstracts/search?q=meadows" title=" meadows"> meadows</a> </p> <a href="https://publications.waset.org/abstracts/166693/biology-of-salema-sarpa-salpa-l-and-population-off-gokceada-northern-aegean-sea-turkiye-a-macro-herbivore-species-living-in-sea-grass-beds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166693.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">17</span> Beam Deflection with Unidirectionality Due to Zeroth Order and Evanescent Wave Coupling in a Photonic Crystal with a Defect Layer without Corrugations under Oblique Incidence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evrim%20Colak">Evrim Colak</a>, <a href="https://publications.waset.org/abstracts/search?q=Andriy%20E.%20Serebryannikov"> Andriy E.

In all of the studied cases, the defect layer is placed such that the symmetry is broken. Two types of deflection are observed depending on whether the zeroth order is coupled or not. These two scenarios can be distinguished from each other by considering the simulated field distribution in PC. In the first deflection type, Floquet-Bloch mode enables zeroth order coupling. The energy of the zeroth order is redistributed between the diffraction orders at the defect layer, providing deflection. In the second type, when zeroth order is not coupled, strong diffractions cause blazing and the evanescent waves deliver energy to higher order diffraction modes. Simulated isofrequency contours can be utilized to estimate the coupling behavior. The defect layer is placed at varying rows, preserving the asymmetry of PC while evancescent waves can still couple to higher order modes. Even for deeply buried defect layer, asymmetric transmission and beam deflection are still encountered when the zeroth order is not coupled. We assume ε=11.4 (refractive index close to that of GaAs and Si) for the PC rods. A possible operation wavelength can be within microwave and infrared range. Since the suggested material is low loss, the structure can be scaled down to operate higher frequencies. Thus, a sample operation wavelength is selected as 1.5μm. Although the structure employs no surface corrugations transmission value T≈0.97 can be achieved by means of diffraction order m=-1. Moreover, utilizing an extra line defect, T value can be increased upto 0.99, under oblique incidence even if the line defect layer is deeply embedded in the photonic crystal. The latter configuration can be used to obtain deflection in one frequency range and can also be utilized for the realization of another functionality like defect-mode wave guiding in another frequency range but still using the same structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20transmission" title="asymmetric transmission">asymmetric transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=beam%20deflection" title=" beam deflection"> beam deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=blazing" title=" blazing"> blazing</a>, <a href="https://publications.waset.org/abstracts/search?q=bi-directional%20splitting" title=" bi-directional splitting"> bi-directional splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=defect%20layer" title=" defect layer"> defect layer</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20beam%20splitting" title=" dual beam splitting"> dual beam splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=Floquet-Bloch%20modes" title=" Floquet-Bloch modes"> Floquet-Bloch modes</a>, <a href="https://publications.waset.org/abstracts/search?q=isofrequency%20contours" title=" isofrequency contours"> isofrequency contours</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20defect" title=" line defect"> line defect</a>, <a href="https://publications.waset.org/abstracts/search?q=oblique%20incidence" title=" oblique incidence"> oblique incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=photonic%20crystal" title=" photonic crystal"> photonic crystal</a>, <a href="https://publications.waset.org/abstracts/search?q=unidirectionality" title=" unidirectionality"> unidirectionality</a> </p> <a href="https://publications.waset.org/abstracts/94547/beam-deflection-with-unidirectionality-due-to-zeroth-order-and-evanescent-wave-coupling-in-a-photonic-crystal-with-a-defect-layer-without-corrugations-under-oblique-incidence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94547.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">262</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">16</span> The Factors That Influence the Self-Sufficiency and the Self-Efficacy Levels among Oncology Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esra%20Danaci">Esra Danaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Tugba%20Kavalali%20Erdogan"> Tugba Kavalali Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevil%20Masat"> Sevil Masat</a>, <a href="https://publications.waset.org/abstracts/search?q=Selin%20Keskin%20Kiziltepe"> Selin Keskin Kiziltepe</a>, <a href="https://publications.waset.org/abstracts/search?q=Tugba%20Cinarli"> Tugba Cinarli</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeliha%20Koc"> Zeliha Koc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted in a descriptive and cross-sectional manner to determine that factors that influence the self-efficacy and self-sufficiency levels among oncology patients. The research was conducted between January 24, 2017 and September 24, 2017 in the oncology and hematology departments of a university hospital in Turkey with 179 voluntary inpatients. The data were collected through the Self-Sufficiency/Self-Efficacy Scale and a 29-question survey, which was prepared in order to determine the sociodemographic and clinical properties of the patients. The Self-Sufficiency/Self-Efficacy Scale is a Likert-type scale with 23 articles. The scale scores range between 23 and 115. A high final score indicates a good self-sufficiency/self-efficacy perception for the individual. The data were analyzed using percentage analysis, one-way ANOVA, Mann Whitney U-test, Kruskal Wallis test and Tukey test. The demographic data of the subjects were as follows: 57.5% were male and 42.5% were female, 82.7% were married, 46.4% were primary school graduate, 36.3% were housewives, 19% were employed, 93.3% had social security, 52.5% had matching expenses and incomes, 49.2% lived in the center of the city. The mean age was 57.1±14.6. It was determined that 22.3% of the patients had lung cancer, 19.6% had leukemia, and 43.6% had a good overall condition. The mean self-sufficiency/self-efficacy score was 83,00 (41-115). It was determined that the patients' self-sufficiency/self-efficacy scores were influenced by some of their socio-demographic and clinical properties. This study has found that the patients had high self-sufficiency/self-efficacy scores. It is recommended that the nursing care plans should be developed to improve their self-sufficiency/self-efficacy levels in the light of the patients' sociodemographic and clinical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oncology" title="oncology">oncology</a>, <a href="https://publications.waset.org/abstracts/search?q=patient" title=" patient"> patient</a>, <a href="https://publications.waset.org/abstracts/search?q=self-efficacy" title=" self-efficacy"> self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=self-sufficiency" title=" self-sufficiency"> self-sufficiency</a> </p> <a href="https://publications.waset.org/abstracts/95832/the-factors-that-influence-the-self-sufficiency-and-the-self-efficacy-levels-among-oncology-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95832.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">170</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> Preparation of Conductive Composite Fiber by the Reduction of Silver Particles onto Hydrolyzed Polyacrylonitrile Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20Okay">Z.

The result of alkaline hydrolysis of PAN fiber could be formed the products with conjugated sequences of –C=N–, acrylamide, sodium acrylate, and amidine. In this study, PAN fiber was hydrolyzed in a solution of sodium hydroxide, and this hydrolyzed PAN (HPAN) fiber was used to prepare conductive composite fiber by silver particles. The electrically conductive PAN fiber has the usage potential to produce variety of materials such as antistatic materials, life jackets and static charge reducing products. We monitored the change in the weight loss values of the PAN fiber with hydrolysis time. It was observed that a 60 % of weight loss was obtained in the fiber weight after 7h hydrolysis under the investigated conditions, but the fiber lost its fibrous structure. The hydrolysis time of 5h was found to be suitable in terms of preserving its fibrous structure. The change in the conductivity values of the composite with the preparation conditions such as hydrolysis time, silver ion concentration was studied. PAN fibers with different degrees of hydrolysis were treated with aqueous solutions containing different concentrations of silver ions by continuous stirring at 20 oC for 30 min, and the composite having the maximum conductivity of 2 S/cm could be prepared. The antibacterial property of the conductive HPAN fibers participated silver was also investigated. While the hydrolysis of the PAN fiber was characterized with FTIR and SEM techniques, the silver reduction process of the HPAN fiber was investigated with SEM and TGA-DTA techniques. The SEM micrographs showed that the surface of HPAN fiber was rougher and much more corroded than that of the PAN fiber.

The defect layer has twice the period of the regular PC segments which sandwich the defect layer. Although the PC has even number of rows, the structural symmetry is broken due to the asymmetric placement of the defect layer with respect to the symmetry axis of the regular PC. The simulations verify that efficient splitting and occurrence of strong diffractions are related to the dispersion properties of the Floquet-Bloch modes of the photonic crystal. Unidirectional and bi-directional splitting, which are associated with asymmetric transmission, arise due to the dominant contribution of the first positive and first negative diffraction orders. The effect of the depth of the defect layer is examined by placing single defect layer in varying rows, preserving the asymmetry of PC. Even for deeply buried defect layer, asymmetric transmission is still valid even if the zeroth order is not coupled. This transmission is due to evanescent waves which reach to the deeply embedded defect layer and couple to higher order modes. In an additional selected performance, whichever surface is illuminated, i.e., in both upper and lower surface illumination cases, incident beam is split into two beams of equal intensity at the output surface where the intensity of the out-going beams are equal for both illumination cases. That is, although the structure is asymmetric, symmetric bidirectional transmission with equal transmission values is demonstrated and the structure mimics the behavior of symmetric structures. Finally, simulation studies including the examination of a coupled-cavity defect for two different permittivity values (close to the permittivity values of GaAs or Si and alumina) reveal unidirectional splitting for a wider band of operation in comparison to the bandwidth obtained in the case of a single embedded defect layer. Since the dielectric materials that are utilized are low-loss and weakly dispersive in a wide frequency range including microwave and optical frequencies, the studied structures should be scalable to the mentioned ranges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20transmission" title="asymmetric transmission">asymmetric transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=beam%20deflection" title=" beam deflection"> beam deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=blazing" title=" blazing"> blazing</a>, <a href="https://publications.waset.org/abstracts/search?q=bi-directional%20splitting" title=" bi-directional splitting"> bi-directional splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=defect%20layer" title=" defect layer"> defect layer</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20beam%20splitting" title=" dual beam splitting"> dual beam splitting</a>, <a href="https://publications.waset.org/abstracts/search?q=Floquet-Bloch%20modes" title=" Floquet-Bloch modes"> Floquet-Bloch modes</a>, <a href="https://publications.waset.org/abstracts/search?q=isofrequency%20contours" title=" isofrequency contours"> isofrequency contours</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20defect" title=" line defect"> line defect</a>, <a href="https://publications.waset.org/abstracts/search?q=oblique%20incidence" title=" oblique incidence"> oblique incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=photonic%20crystal" title=" photonic crystal"> photonic crystal</a>, <a href="https://publications.waset.org/abstracts/search?q=unidirectionality" title=" unidirectionality"> unidirectionality</a> </p> <a href="https://publications.waset.org/abstracts/94548/design-of-photonic-crystal-with-defect-layer-to-eliminate-interface-corrugations-for-obtaining-unidirectional-and-bidirectional-beam-splitting-under-normal-incidence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94548.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">184</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> 3+3 Regional Cooperation Format and the South Caucasus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eka%20Darbaidze">Eka Darbaidze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to its important geopolitical location and strategic economic situation, the South Caucasus has been a region that has been a crossroads of interests between different states and empires since ancient times. Over the centuries, the forms of international relations with regard to the South Caucasus region have been constantly changing, however, the national interests of the Caucasian nations as well as the interests of the regional hegemonic powers in relation to the countries of the South Caucasus have remained almost unchanged. The conflict-ridden South Caucasus's attempt to create a new format of regional cooperation has a rather rich history, dating back to the collapse of the Soviet Union. However, despite the diversity of initiatives, they do not deviate from the format of political statements and it is natural that the case was never settled before their implementation, as none of the previous cooperation initiatives was able to reach all members of the region. The current regional co-operation platform is linked to the name of Turkish President Recep Tayyip Erdogan, who spoke out about the initiative during a visit to Azerbaijan. The so-called 3 + 3 platform for regional cooperation involves cooperation between three countries in the South Caucasus (Armenia, Azerbaijan and Georgia) and three "big neighbors" - Russia, Turkey and Iran. Very soon, the initiative received a positive response from the authorities of Azerbaijan, Iran and Armenia. According to them, this cooperation platform will strengthen cooperation between the countries involved in the regional platform and will focus on security, economic and transport issues. Our goal is to determine the interests of the main regional actors involved in the South Caucasus Cooperation Platform (3 + 3): Iran, Russia and Turkey. Our goal is also to determine what threats, risks or benefits may be associated with the involvement of the three countries of the South Caucasus: Azerbaijan, Armenia and Georgia in this platform and what will be the consequences for Georgia, whose 20% of its internationally recognized borders are still occupied by Russia and whose territory is still under creeping occupation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=South%20Caucasus" title="South Caucasus">South Caucasus</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgia%27s%20interest" title=" Georgia's interest"> Georgia's interest</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20interests%20of%20Iran" title=" the interests of Iran"> the interests of Iran</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20interests%20of%20Turkey" title=" the interests of Turkey"> the interests of Turkey</a>, <a href="https://publications.waset.org/abstracts/search?q=Russian%20interests" title=" Russian interests"> Russian interests</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgia%27s%20occupation" title=" Georgia's occupation"> Georgia's occupation</a> </p> <a href="https://publications.waset.org/abstracts/148305/33-regional-cooperation-format-and-the-south-caucasus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148305.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">208</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> The Determination of Self-Esteem, Life Satisfaction, Anxiety and Depression Levels among Patients with Stoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tugba%20Cinarli">Tugba Cinarli</a>, <a href="https://publications.waset.org/abstracts/search?q=Tugba%20Kavalali%20Erdogan"> Tugba Kavalali Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevil%20Masat"> Sevil Masat</a>, <a href="https://publications.waset.org/abstracts/search?q=Dilek%20Kiymaz"> Dilek Kiymaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nida%20Kiyici"> Nida Kiyici</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeliha%20Koc"> Zeliha Koc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted in a descriptive and cross-sectional manner, in order to determine the self-esteem, life satisfaction and depression/anxiety levels of the patients with stoma. The study was conducted between June 15, 2016 and June 15, 2017 among 196 oncology patients that were hospitalized in the general surgery clinic of a public hospital in Turkey. The case group consisted of 98 cancer patients with stoma and the control group consisted of 98 cancer patients without stoma. The data were collected through the Coopersmith Self-Esteem Scale, Life Satisfaction Scale, the Hospital Anxiety and Depression Scale, and a 21-question survey that aimed to determine the sociodemographic and clinical properties of the patients. The data were analyzed with percentage analysis, Mann Whitney U-test, Chi-square test and Spearmen’s correlation test. It was determined that for the case group; 44.9% had colon cancer, 29.6% had rectal cancer; 50% underwent temporary colostomia, 15.3% underwent permanent colostomia, 34.7% underwent temporary ileostomy. The experimental group's findings for the Coopersmith Self-Esteem Scale, Life Satisfaction Scale, the Anxiety Subscale and the Depression subscale were 64 (20 - 84), 17 (5 - 38), 10 (1 - 18), and 9 (1 - 19), respectively. The control group's findings for the Coopersmith Self-Esteem Scale, Life Satisfaction Scale, the Anxiety Subscale and the Depression Subscale were 68 (32 - 92), 21 (7 - 31), 8.5 (1 - 18), and 8 (1 - 18), respectively. It was found that the Coopersmith Self-Esteem Scale, Life Satisfaction Scale, and the Anxiety Subscale findings were significantly different for the experimental and control groups (p<0.05). It was determined that the self-esteem levels were positively correlated with life satisfaction and negatively correlated with anxiety and depression; also, the life satisfaction levels were negatively correlated with anxiety and depression. It is suggested that the nursing interventions should be planned in order to improve life-satisfaction and self-esteem levels of the patients, and to decrease depression and anxiety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxiety" title="anxiety">anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20satisfaction" title=" life satisfaction"> life satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title=" self-esteem"> self-esteem</a> </p> <a href="https://publications.waset.org/abstracts/95821/the-determination-of-self-esteem-life-satisfaction-anxiety-and-depression-levels-among-patients-with-stoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95821.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">173</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> Improvement in Drying Characteristics of Raisin by Carbonic Maceration– Process Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nursac%20Akyol">Nursac Akyol</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20S.%20Turan"> Merve S.

During this procedure, grapes are open to some environmental effects besides the adverse effects of the long drying period. Thus, there is a need to develop an alternative method being applicable instead of traditional one. To this extent, a combination of a potential pretreatment (carbonic maceration, CM) with convectional oven drying was examined. CM application was used in raisin production (grape drying) as a pretreatment process before oven drying. Pressure, temperature and time were examined as application parameters of CM. In conventional oven drying, the temperature is a process variable. The aim is to find out how CM and convectional drying processes affect the drying characteristics of grapes as well as their physical and chemical properties. For this purpose, the response surface method was used to determine both the effects of the variables and the optimum pretreatment and drying conditions. The optimum conditions of CM for raisin production were 0.3 MPa of pressure value, 4°C of application temperature and 8 hours of application time. The optimized drying temperature was 77°C. The results showed that the application of CM before the drying process improved the drying characteristics. Drying took only 389 minutes for grapes pretreated by CM under optimum conditions and 495 minutes for the control group dried only by the conventional drying process. According to these results, a decrease of 21% was achieved in the time requirement for raisin production. Also, it was observed that the samples dried under optimum conditions had similar physical properties as those the control group had. It was seen that raisin, which was dried under optimum conditions were in better condition in terms of some of the bioactive contents compared to control groups. In light of all results, it is seen that CM has an important potential in the industrial drying of grape samples.

With the advancement in communication and information technology, cyberbullying has expanded its boundaries among students in schools. Thus, parents, psychologists, educators, and lawmakers must become aware of the potential risks of this phenomenon. In the light of these perspectives, this study aims to investigate the relationships between cyberbullying perception and Facebook attitudes of Turkish students. A survey method was used for the study and the data were collected by “Cyberbullying Perception Scale”, “Facebook Attitude Scale” and “Personal Information Form”. For this purpose, study has been conducted during 2014-2015 academic year, with a total of 748 students with 493 male (%65.9) and 255 female (%34.1) from randomly selected high schools. In the analysis of data Pearson correlation and multiple regression analysis, multivariate analysis of variance (MANOVA) and Scheffe post hoc test has been used. At the end of the study, the results displayed a negative correlation between Turkish students’ Facebook attitudes and cyberbullying perception (r=-.210; p<0.05). In order to identify the predictors of students’ cyberbullying perception, multiple regression analysis was used. As a result, significant relations were detected between cyberbullying perception and independent variables (F=5.102; p<0.05). Independent variables together explain 11.0% of the total variance in cyberbullying scores. The variables that significantly predict the students’ cyberbullying perception are Facebook attitudes (t=-5.875; p<0.05), and gender (t=3.035; p<0.05). In order to calculate the effects of independent variables on students’ Facebook attitudes and cyberbullying perception MANOVA was conducted. The results of the MANOVA indicate that the Facebook attitudes and cyberbullying perception were significantly differed according to students’ gender, age, educational attainment of the mother, educational attainment of the father, income of the family and daily usage of internet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=facebook" title="facebook">facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=cyberbullying" title=" cyberbullying"> cyberbullying</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20usage" title=" internet usage"> internet usage</a> </p> <a href="https://publications.waset.org/abstracts/30462/exploring-the-relationships-between-cyberbullying-perceptions-and-facebook-attitudes-of-turkish-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30462.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">402</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> An Invasive Lessepsian Species, Golden-Banded Goatfish, Upeneus Moluccensis Population from Iskenderun Bay, the Eastern Mediterranean Sea, Türkiye, With Some Biological Notes: The Effects of Climate Differences and Opening of Suez Canal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatice%20Torcu%20Koc">Hatice Torcu Koc</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeliha%20Erdogan"> Zeliha Erdogan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presented the investigation of the population structure of Upeneus moluccensis in order to provide further knowledge and to compare the data with the studies before and thus help in the management of the population in the İskenderun Bay. For this purpose, a total of 370 golden-banded goatfish were caught by a commercial vessel monthly at a depth of 50-60 m. from İskenderun Bay in the years 2016-2018. Von Bertalanffy growth equation,length-weight relationships, sex ratio, age, condition, and gonado and hepato-somatic index values of U.peneus moluccensis specimens were determined. For this, the lengths and weights were measured using a dial caliper of 0.05 mm and a sensitive balance. Total lengths were 7.2–17.5 cm in females and 7.0–17.9 cm in males, while total weight ranges for females and males were 3.91-64.26 g and 3.69-60.95 g., respectively. Length-weight relationship for all individuals was calculated as W=0.004*L³ ³⁸, R²=0.85. Growth parameter was determined as L∞= 20.75 cm, k=0.33, t₀= - 0.56. The age readings were done by using the Bhattacharya method. The population was composed of 3 ages (1-3). The sex ratio was found as 1:1.42, corresponding to 41.4% males and 58.6% females, in favor of females (p<0.05). Values of the average condition and hepatosomatic index were found to be shown a similar pattern for males (1.088, 1.104) and females (1.124, 1.177), respectively. According to GSI values, the spawning period started in March and increased to April, May, and September. It was estimated that total (Z) mortality, natural (M) mortality, and fishing (F) mortality rates were estimated as Z=0.94 year-¹, M=0.033 year-¹, and F=0.63 year-¹, respectively. As the exploitation rate was estimated to be E=0.67, it can be shown that the golden-banded goatfish stock was influenced by overfishing. The findings of this study are very important to point out the population of U. moluccensis, which penetrated into the eastern Mediterranean Sea of Türkiye due to global heating and the construction of the Suez Canal and to be basic data for the next fisheries investigations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biology" title="biology">biology</a>, <a href="https://publications.waset.org/abstracts/search?q=U.%20moluccensis" title=" U. moluccensis"> U. moluccensis</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive" title=" invasive"> invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=lessepsian" title=" lessepsian"> lessepsian</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B0skenderun%20Bay" title=" İskenderun Bay"> İskenderun Bay</a> </p> <a href="https://publications.waset.org/abstracts/166870/an-invasive-lessepsian-species-golden-banded-goatfish-upeneus-moluccensis-population-from-iskenderun-bay-the-eastern-mediterranean-sea-turkiye-with-some-biological-notes-the-effects-of-climate-differences-and-opening-of-suez-canal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166870.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">74</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 Role of Motivational Beliefs and Self-Regulated Learning Strategies in The Prediction of Mathematics Teacher Candidates' Technological Pedagogical And Content Knowledge (TPACK) Perceptions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Erdo%C4%9Fan">Ahmet Erdoğan</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eahin%20Kesici"> Şahin Kesici</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Balo%C4%9Flu"> Mustafa Baloğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information technologies have lead to changes in the areas of communication, learning, and teaching. Besides offering many opportunities to the learners, these technologies have changed the teaching methods and beliefs of teachers. What the Technological Pedagogical Content Knowledge (TPACK) means to the teachers is considerably important to integrate technology successfully into teaching processes. It is necessary to understand how to plan and apply teacher training programs in order to balance students’ pedagogical and technological knowledge. Because of many inefficient teacher training programs, teachers have difficulties in relating technology, pedagogy and content knowledge each other. While providing an efficient training supported with technology, understanding the three main components (technology, pedagogy and content knowledge) and their relationship are very crucial. The purpose of this study is to determine whether motivational beliefs and self-regulated learning strategies are significant predictors of mathematics teacher candidates' TPACK perceptions. A hundred seventy five Turkish mathematics teachers candidates responded to the Motivated Strategies for Learning Questionnaire (MSLQ) and the Technological Pedagogical And Content Knowledge (TPACK) Scale. Of the group, 129 (73.7%) were women and 46 (26.3%) were men. Participants' ages ranged from 20 to 31 years with a mean of 23.04 years (SD = 2.001). In this study, a multiple linear regression analysis was used. In multiple linear regression analysis, the relationship between the predictor variables, mathematics teacher candidates' motivational beliefs, and self-regulated learning strategies, and the dependent variable, TPACK perceptions, were tested. It was determined that self-efficacy for learning and performance and intrinsic goal orientation are significant predictors of mathematics teacher candidates' TPACK perceptions. Additionally, mathematics teacher candidates' critical thinking, metacognitive self-regulation, organisation, time and study environment management, and help-seeking were found to be significant predictors for their TPACK perceptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=candidate%20mathematics%20teachers" title="candidate mathematics teachers">candidate mathematics teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=motivational%20beliefs" title=" motivational beliefs"> motivational beliefs</a>, <a href="https://publications.waset.org/abstracts/search?q=self-regulated%20learning%20strategies" title=" self-regulated learning strategies"> self-regulated learning strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20and%20pedagogical%20knowledge" title=" technological and pedagogical knowledge"> technological and pedagogical knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=content%20knowledge" title=" content knowledge"> content knowledge</a> </p> <a href="https://publications.waset.org/abstracts/23616/the-role-of-motivational-beliefs-and-self-regulated-learning-strategies-in-the-prediction-of-mathematics-teacher-candidates-technological-pedagogical-and-content-knowledge-tpack-perceptions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23616.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">482</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> Enabling Socio Cultural Sustainability of the "Thousand and One Churches" Archaeological Site </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Erdogan">E.

Sustainable tourism aims to preserve natural, historical, cultural, and social resources, also by supporting economic progress protecting economic development and environmental values that emerge as a consequence of tourism activities. Cultural tourism feeds on sustainable cultural treasures inherently and is the most effective touristic activity. Traditional configurations and structural characteristics play an important role in generating cultural tourism in a region. Sustainable cultural tourism is related to trips upon people who embark with the aim of visiting culturally rich regions, learning about and observing fast-disappearing lifestyles and collecting cultural values as memories. With its huge tourism potential, Karadağ is the most significant cultural asset of the Karaman province, possessing unique riches in terms of cultural world history. Host to one of the most important Byzantine cities in Anatolia, Karadağ is like an open-air museum with its unparalleled architectural structures. There is a village named Madenşehir in the plain at the outskirts of Karadağ, near to which are located the “Thousand and One Churches” ruins. The 80-household house is located near the ruins in an area that been declared a 1st degree historic preservation district. stones gathered from local churches were used in the construction of these households. A ministry has assigned a new residential site near the boundaries of the 2nd degree preservation district, and the decision has been made to move the occupants to this area. The most important issue here is to enable locals’ sociocultural and socioeconomic sustainability. It is also important to build these structures in a manner compatible with the historical visual look, ecological system and environmental awareness. Therefore this new site will be planned as touristic area in terms of sustainable cultural tourism and in these new plans, shall fulfill functions oriented toward both tourists and locals. It is very important that this change be sustainable and also support cultural tourism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20tourism" title="cultural tourism">cultural tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20village%20settlement" title=" new village settlement"> new village settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=socio%20cultural%20sustainability" title=" socio cultural sustainability"> socio cultural sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=%E2%80%9Cthousand%20and%20one%20churches%E2%80%9D%20site" title=" “thousand and one churches” site "> “thousand and one churches” site </a> </p> <a href="https://publications.waset.org/abstracts/30495/enabling-socio-cultural-sustainability-of-the-thousand-and-one-churches-archaeological-site" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30495.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">398</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> The Gezi Park Protests in the Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S%C3%BCleyman%20Hakan%20Yilmaz">Süleyman Hakan Yilmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasemin%20G%C3%BClsen%20Yilmaz"> Yasemin Gülsen Yilmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Gezi Park protests of 2013 have significantly changed the Turkish agenda and its effects have been felt historically. The protests, which rapidly spread throughout the country, were triggered by the proposal to recreate the Ottoman Army Barracks to function as a shopping mall on Gezi Park located in Istanbul’s Taksim neighbourhood despite the oppositions of several NGOs and when trees were cut in the park for this purpose. Once the news that construction vehicles entered the park on May 27 spread on social media, activists moved into the park to stop the demolition, against whom the police used disproportioned force. With this police intervention and the then prime-minister Tayyip Erdoğan's insistent statements about the construction plans, the protests turned into anti-government demonstrations, which then spread to the rest of the country, mainly in big cities like Ankara and Izmir. According to the Ministry of Internal Affairs’ June 23rd reports, 2.5 million people joined the demonstrations in 79 provinces, that is all of them, except for the provinces of Bayburt and Bingöl, while even more people shared their opinions via social networks. As a result of these events, 8 civilians and 2 security personnel lost their lives, namely police chief Mustafa Sarı, police officer Ahmet Küçükdağ, citizens Mehmet Ayvalıtaş, Abdullah Cömert, Ethem Sarısülük, Ali İsmail Korkmaz, Ahmet Atakan, Berkin Elvan, Burak Can Karamanoğlu, Mehmet İstif, and Elif Çermik, and 8163 more were injured. Besides being a turning point in Turkish history, the Gezi Park protests also had broad repercussions in both in Turkish and in global media, which focused on Turkey throughout the events. Our study conducts content analysis of three Turkish reporting newspapers with varying ideological standpoints, Hürriyet, Cumhuriyet ve Yeni Şafak, in order to reveal their basic approach to columns casting in context of the Gezi Park protests. Columns content relating to the Gezi protests were treated and analysed for this purpose. The aim of this study is to understand the social effects of the Gezi Park protests through media samples with varying political attitudes towards news casting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gezi%20Park" title="Gezi Park">Gezi Park</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a>, <a href="https://publications.waset.org/abstracts/search?q=news%20casting" title=" news casting"> news casting</a>, <a href="https://publications.waset.org/abstracts/search?q=columns" title=" columns"> columns</a> </p> <a href="https://publications.waset.org/abstracts/26539/the-gezi-park-protests-in-the-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26539.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">433</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> Effect of Two Different Method for Juice Processing on the Anthocyanins and Polyphenolics of Blueberry (Vaccinium corymbosum)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Ercan">Onur Ercan</a>, <a href="https://publications.waset.org/abstracts/search?q=Buket%20Askin"> Buket Askin</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdogan%20Kucukoner"> Erdogan Kucukoner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blueberry (Vaccinium corymbosum, bluegold) has become popular beverage due to their nutritional values such as vitamins, minerals, and antioxidants. In the study, the effects of pressing, mashing, enzymatic treatment, and pasteurization on anthocyanins, colour, and polyphenolics of blueberry juice (BJ) were studied. The blueberry juice (BJ) was produced with two different methods that direct juice extraction (DJE) and mash treatment process (MTP) were applied. After crude blueberry juice (CBJ) production, the samples were first treated with commercial enzymes [Novoferm-61 (Novozymes A/S) (2–10 mL/L)], to break down the hydrocolloid polysaccharides, mainly pectin and starch. The enzymes were added at various concentrations. The highest transmittance (%) was obtained for Novoferm-61 at a concentration of 2 mL/L was 66.53%. After enzymatic treatment, clarification trials were applied to the enzymatically treated BJs with adding various amounts of bentonite (10%, w/v), gelatin (1%, w/v) and kiselsol (15%, v/v). The turbidities of the clarified samples were then determined. However, there was no significant differences between transmittances (%) for samples. For that, only enzymatic treatment was applied to the blueberry juice processing (DDBJ, depectinized direct blueberry juice). Based on initial pressing process made to evaluate press function, it was determined that pressing fresh blueberries with no other processing did not render adequate juice due to lack of liquefaction. Therefore, the blueberries were mash into small pieces (3 mm) and then enzymatic treatments and clarification trials were performed. Finally, both BJ samples were pasteurized. Compositional analyses, colour properties, polyphenols and antioxidant properties were compared. Enzymatic treatment caused significant reductions in ACN content (30%) in Direct Blueberry Juice Processing (DBJ), while there was a significant increasing in Mash Treatment Processing (MTP). Overall anthocyanin levels were higher intreated samples after each processing step in MTP samples, but polyphenolic levels were slightly higher for both processes (DBJ and MTP). There was a reduction for ACNs and polyphenolics only after pasteurization. It has a result that the methods for tried to blueberry juice is suitable into obtain fresh juice. In addition, we examined fruit juice during processing stages; anthocyanin, phenolic substance content and antioxidant activity are higher, and yield is higher in fruit juice compared to DBJ method in MTP method, the MTP method should be preferred in processing juice of blueberry into fruit juice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthocyanins" title="anthocyanins">anthocyanins</a>, <a href="https://publications.waset.org/abstracts/search?q=blueberry" title=" blueberry"> blueberry</a>, <a href="https://publications.waset.org/abstracts/search?q=depectinization" title=" depectinization"> depectinization</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a> </p> <a href="https://publications.waset.org/abstracts/156482/effect-of-two-different-method-for-juice-processing-on-the-anthocyanins-and-polyphenolics-of-blueberry-vaccinium-corymbosum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156482.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">92</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> Influence of Wind Induced Fatigue Damage in the Reliability of Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emilio%20A.%20Berny-Brandt">Emilio A.

Ruiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Steel tubular towers serving as support structures for large wind turbines are subject to several hundred million stress cycles arising from the turbulent nature of the wind. This causes high-cycle fatigue which can govern tower design. The practice of maintaining the support structure after wind turbines reach its typical 20-year design life have become common, but without quantifying the changes in the reliability on the tower. There are several studies on this topic, but most of them are based on the S-N curve approach using the Miner’s rule damage summation method, the de-facto standard in the wind industry. However, the qualitative nature of Miner’s method makes desirable the use of fracture mechanics to measure the effects of fatigue in the capacity curve of the structure, which is important in order to evaluate the integrity and reliability of these towers. Temporal and spatially varying wind speed time histories are simulated based on power spectral density and coherence functions. Simulations are then applied to a SAP2000 finite element model and step-by-step analysis is used to obtain the stress time histories for a range of representative wind speeds expected during service conditions of the wind turbine. Rainflow method is then used to obtain cycle and stress range information of each of these time histories and a statistical analysis is performed to obtain the distribution parameters of each variable. Monte Carlo simulation is used here to evaluate crack growth over time in the tower base using the Paris-Erdogan equation. A nonlinear static pushover analysis to assess the capacity curve of the structure after a number of years is performed. The capacity curves are then used to evaluate the changes in reliability of a steel tower located in Oaxaca, Mexico, where wind energy facilities are expected to grow in the near future. Results show that fatigue on the tower base can have significant effects on the structural capacity of the wind turbine, especially after the 20-year design life when the crack growth curve starts behaving exponentially. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack%20growth" title="crack growth">crack growth</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation" title=" Monte Carlo simulation"> Monte Carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20reliability" title=" structural reliability"> structural reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbines" title=" wind turbines"> wind turbines</a> </p> <a href="https://publications.waset.org/abstracts/22163/influence-of-wind-induced-fatigue-damage-in-the-reliability-of-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22163.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">517</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> Screening of Antagonistic/Synergistic Effect between Lactic Acid Bacteria (LAB) and Yeast Strains Isolated from Kefir</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mihriban%20Korukluoglu">Mihriban Korukluoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Goksen%20Arik"> Goksen Arik</a>, <a href="https://publications.waset.org/abstracts/search?q=Cagla%20Erdogan"> Cagla Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Selen%20Kocakoglu"> Selen Kocakoglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kefir is a traditional fermented refreshing beverage which is known for its valuable and beneficial properties for human health. Mainly yeast species, lactic acid bacteria (LAB) strains and fewer acetic acid bacteria strains live together in a natural matrix named “kefir grain”, which is formed from various proteins and polysaccharides. Different microbial species live together in slimy kefir grain and it has been thought that synergetic effect could take place between microorganisms, which belong to different genera and species. In this research, yeast and LAB were isolated from kefir samples obtained from Uludag University Food Engineering Department. The cell morphology of isolates was screened by microscopic examination. Gram reactions of bacteria isolates were determined by Gram staining method, and as well catalase activity was examined. After observing the microscopic/morphological and physical, enzymatic properties of all isolates, they were divided into the groups as LAB and/or yeast according to their physicochemical responses to the applied examinations. As part of this research, the antagonistic/synergistic efficacy of the identified five LAB and five yeast strains to each other were determined individually by disk diffusion method. The antagonistic or synergistic effect is one of the most important properties in a co-culture system that different microorganisms are living together. The synergistic effect should be promoted, whereas the antagonistic effect is prevented to provide effective culture for fermentation of kefir. The aim of this study was to determine microbial interactions between identified yeast and LAB strains, and whether their effect is antagonistic or synergistic. Thus, if there is a strain which inhibits or retards the growth of other strains found in Kefir microflora, this circumstance shows the presence of antagonistic effect in the medium. Such negative influence should be prevented, whereas the microorganisms which have synergistic effect on each other should be promoted by combining them in kefir grain. Standardisation is the most desired property for industrial production. Each microorganism found in the microbial flora of a kefir grain should be identified individually. The members of the microbial community found in the glue-like kefir grain may be redesigned as a starter culture regarding efficacy of each microorganism to another in kefir processing. The main aim of this research was to shed light on more effective production of kefir grain and to contribute a standardisation of kefir processing in the food industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antagonistic%20effect" title="antagonistic effect">antagonistic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=kefir" title=" kefir"> kefir</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid%20bacteria%20%28LAB%29" title=" lactic acid bacteria (LAB)"> lactic acid bacteria (LAB)</a>, <a href="https://publications.waset.org/abstracts/search?q=synergistic" title=" synergistic"> synergistic</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a> </p> <a href="https://publications.waset.org/abstracts/61707/screening-of-antagonisticsynergistic-effect-between-lactic-acid-bacteria-lab-and-yeast-strains-isolated-from-kefir" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61707.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">280</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> Symmetric Corticobasal Degeneration: Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sultan%20%C3%87a%C4%9F%C4%B1r%C4%B1c%C4%B1">Sultan Çağırıcı</a>, <a href="https://publications.waset.org/abstracts/search?q=Arsida%20Bajrami"> Arsida Bajrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Beyza%20Aslan"> Beyza Aslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hac%C4%B1%20Ali%20Erdo%C4%9Fan"> Hacı Ali Erdoğan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nejla%20S%C3%B6zer%20Top%C3%A7ular"> Nejla Sözer Topçular</a>, <a href="https://publications.waset.org/abstracts/search?q=Dilek%20Bozkurt"> Dilek Bozkurt</a>, <a href="https://publications.waset.org/abstracts/search?q=Vildan%20Yayla"> Vildan Yayla </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Corticobasal syndrome (CBS) is phenotypically characterized by asymmetric rigidity, apraxia, alien-limb phenomenon, cortical sensory loss, dystonia and myoclonus. The underlying pathologies consists of corticobasal degeneration (CBD), progressive supra nuclear palsy, Alzheimer's, Creutzfeldt-Jakob and frontotemporal degeneration. CBD is a degenerative disease with clinical symptoms related to the prominent involvement of cerebral cortex and basal ganglia. CBD is a pathological diagnosis and antemortem clinical diagnosis may change many times. In this paper, we described the clinical features and discussed a cases diagnosed with symmetric CBS because of its rarity. Case: Seventy-five-year-old woman presented with a three years history of difficulty in speaking and reading. Involuntary hand jerks and slowness of movement also had began in the last six months. In the neurological examination the patient was alert but not fully oriented. The speech was non-fluent, word finding difficulties were present. Bilateral limited upgaze, bradimimia, bilateral positive cogwheel' rigidity but prominent in the right side, postural tremor and negative myoclonus during action on the left side were detected. Receptive language was normal but expressive language and repetition were impaired. Acalculia, alexia, agraphia and apraxia were also present. CSF findings were unremarkable except for elevated protein level (75 mg/dL). MRI revealed bilateral symmetric cortical atrophy prominent in the frontoparietal region. PET showed hypometabolism in the left caudate nucleus. Conclusion: The increase of data related to neurodegenerative disorders associated with dementia, movement disorders and other findings results in an expanded range of diagnosis and transitions between clinical diagnosis. When considered the age of onset, clinical symptoms, imaging findings and prognosis of this patient, clinical diagnosis was CBS and pathologic diagnosis as probable CBD. Imaging of CBD usually consist of typical asymmetry between hemispheres. Still few cases with clinical appearance of CBD may show symmetrical cortical cerebral atrophy. It is presented this case who was diagnosed with CBD although we found symmetrical cortical cerebral atrophy in MRI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=symmetric%20cortical%20atrophy" title="symmetric cortical atrophy">symmetric cortical atrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=corticobasal%20degeneration" title=" corticobasal degeneration"> corticobasal degeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=corticobasal%20syndrome" title=" corticobasal syndrome"> corticobasal syndrome</a> </p> <a href="https://publications.waset.org/abstracts/29477/symmetric-corticobasal-degeneration-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29477.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">458</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> Anisakidosis in Turkey: Serological Survey and Risk for Humans</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Akdur%20%C3%96zt%C3%BCrk">E.

Infection with anisakid larvae can lead to gastric, intestinal, extra-gastrointestinal and gastroallergic forms of the disease. Anisakid parasites have been reported in almost all seas, particularly in the Mediterranean Sea. There is a remarkably high level of risk exposure to these zoonotic parasites as they are present in economically and ecologically important fish of Europe. Anisakid L3 larvae have been also detected in several fish species from the Aegean Sea. Turkey is a peninsular country surrounded by Black, Aegean and the Mediterranean Sea. In this country, fishing habit and fishery product consumption are highly common. In recent years, there was also an increase in the consumption of raw fish due to the increasing interest in the cuisine of the Far East countries. In different regions of Turkey, A. simplex (inMerluccius Merluccius Scomber japonicus, Trachurus mediterraneus, Sardina pilchardus, Engraulis encrasicolus, etc.), Anisakis spp., Contraceucum spp., Pseudoterronova spp. and, C. aduncum were identified as well. Although it is accepted both the presence of anisakid parasites in fish and fishery products in Turkey and the presence of Turkish people with allergic manifestations after fish consumption, there are no reports of human anisakiasis in this country. Given the high prevalence of anisakid parasites in the country, the absence of reports is likely not due to the absence of clinical cases rather to the unavailability of diagnostic tools and the low awareness of the presence of this infection. The aim of the study was to set up an IgE-Western Blot (WB) based test to detect the anisakidosis sensitization among Turkish people with a history of allergic manifestation related to fish consumption. To this end, crude worm antigens (CWA) and allergen enriched fraction (50-66% ) were prepared from L3 of A. simplex (s.l.) collected from Lepidopus caudatus fished in the Mediterranean Sea. These proteins were electrophoretically separated and transferred into the nitrocellulose membranes. By WB, specific proteins recognized by positive control serum samples from sensitized patients were visualized on nitrocellulose membranes by a colorimetric reaction. The CWA and 50–66% fraction showed specific bands, mainly due to Ani s 1 (20-22 kD) and Ani s 4 (9-10 kD). So far, a total of 7 serum samples from people with allergic manifestation and positive skin prick test (SPT) after fish consumption, have been tested and all of them resulted negative by WB, indicating the lack of sensitization to anisakids. This preliminary study allowed to set up a specific test and evidence the lack of correlation between both tests, SPT and WB. However, the sample size should be increased to estimate the anisakidosis burden in Turkish people. <p class="card-text"><strong>Keywords:</strong> <a
