Accurate evaluation of obesity in children requires difficult and detailed investigation. In our study, obesity in children was evaluated using new body fat ratios and indices. Assessment of anthropometric measurements, as well as some ratios, is important because of the evaluation of gender differences particularly during the late periods of obesity. A total of 239 children; 168 morbid obese (MO) (81 girls and 87 boys) and 71 normal weight (NW) (40 girls and 31 boys) children, participated in the study. Informed consent forms signed by the parents were obtained. Ethics Committee approved the study protocol. Mean ages (years)±SD calculated for MO group were 10.8±2.9 years in girls and 10.1±2.4 years in boys. The corresponding values for NW group were 9.0±2.0 years in girls and 9.2±2.1 years in boys. Mean body mass index (BMI)±SD values for MO group were 29.1±5.4 kg/m<sup>2</sup> and 27.2±3.9 kg/m<sup>2 </sup>in girls and boys, respectively. These values for NW group were calculated as 15.5±1.0 kg/m<sup>2</sup> in girls and 15.9±1.1 kg/m<sup>2 </sup>in boys. Groups were constituted based upon BMI percentiles for age-and-sex values recommended by WHO. Children with percentiles >99 were grouped as MO and children with percentiles between 85 and 15 were considered NW. The anthropometric measurements were recorded and evaluated along with the new ratios such as trunk-to-appendicular fat ratio, as well as indices such as Index-I and Index-II. The body fat percent values were obtained by bio-electrical impedance analysis. Data were entered into a database for analysis using SPSS/PASW 18 Statistics for Windows statistical software. Increased waist-to-hip circumference (C) ratios, decreased head-to-neck C, height ‘to’ ‘two’-‘to’-waist C and height ‘to’ ‘two’-‘to’-hip C ratios were observed in parallel with the development of obesity (p≤0.001). Reference value for height ‘to’ ‘two’-‘to’-hip ratio was detected as approximately 1.0. Index-II, based upon total body fat mass, showed much more significant differences between the groups than Index-I based upon weight. There was not any difference between trunk-to-appendicular fat ratios of NW girls and NW boys (p≥0.05). However, significantly increased values for MO girls in comparison with MO boys were observed (p≤0.05). This parameter showed no difference between NW and MO states in boys (p≥0.05). However, statistically significant increase was noted in MO girls compared to their NW states (p≤0.001). Trunk-to-appendicular fat ratio was the only fat-based parameter, which showed gender difference between NW and MO groups. This study has revealed that body ratios and formula based upon body fat tissue are more valuable parameters than those based on weight and height values for the evaluation of morbid obesity in children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropometry" title="anthropometry">anthropometry</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood%20obesity" title=" childhood obesity"> childhood obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=morbid%20obesity" title=" morbid obesity"> morbid obesity</a> </p> <a href="https://publications.waset.org/abstracts/42289/gender-differences-in-morbid-obese-children-clinical-significance-of-two-diagnostic-obesity-notation-model-assessment-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42289.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">325</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">37</span> Laboratory Indices in Late Childhood Obesity: The Importance of DONMA Indices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orkide%20Donma">Orkide Donma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20M.%20Donma"> Mustafa M.

Especially morbid obesity is an important problem for the children because of the associated diseases such as diabetes mellitus, cancer and cardiovascular diseases. In this study, body mass index (BMI), body fat ratios, anthropometric measurements and ratios were evaluated together with different laboratory indices upon evaluation of obesity in morbidly obese (MO) children. Children with nutritional problems participated in the study. Written informed consent was obtained from the parents. Study protocol was approved by the Ethics Committee. Sixty-two MO girls aged 129.5±35.8 months and 75 MO boys aged 120.1±26.6 months were included into the scope of the study. WHO-BMI percentiles for age-and-sex were used to assess the children with those higher than 99<sup>th</sup> as morbid obesity. Anthropometric measurements of the children were recorded after their physical examination. Bio-electrical impedance analysis was performed to measure fat distribution. Anthropometric ratios, body fat ratios, Index-I and Index-II as well as insulin sensitivity indices (ISIs) were calculated. Girls as well as boys were binary grouped according to homeostasis model assessment-insulin resistance (HOMA-IR) index of <2.5 and >2.5, fasting glucose to insulin ratio (FGIR) of <6 and >6 and quantitative insulin sensitivity check index (QUICKI) of <0.33 and >0.33 as the frequently used cut-off points. They were evaluated based upon their BMIs, arms, legs, trunk, whole body fat percentages, body fat ratios such as fat mass index (FMI), trunk-to-appendicular fat ratio (TAFR), whole body fat ratio (WBFR), anthropometric measures and ratios [waist-to-hip, head-to-neck, thigh-to-arm, thigh-to-ankle, height/2-to-waist, height/2-to-hip circumference (C)]. SPSS/PASW 18 program was used for statistical analyses. p≤0.05 was accepted as statistically significance level. All of the fat percentages showed differences between below and above the specified cut-off points in girls when evaluated with HOMA-IR and QUICKI. Differences were observed only in arms fat percent for HOMA-IR and legs fat percent for QUICKI in boys (p≤ 0.05). FGIR was unable to detect any differences for the fat percentages of boys. Head-to-neck C was the only anthropometric ratio recommended to be used for all ISIs (p≤0.001 for both girls and boys in HOMA-IR, p≤0.001 for girls and p≤0.05 for boys in FGIR and QUICKI). Indices which are recommended for use in both genders were Index-I, Index-II, HOMA/BMI and log HOMA (p≤0.001). FMI was also a valuable index when evaluated with HOMA-IR and QUICKI (p≤0.001). The important point was the detection of the severe significance for HOMA/BMI and log HOMA while they were evaluated also with the other indices, FGIR and QUICKI (p≤0.001). These parameters along with Index-I were unique at this level of significance for all children. In conclusion, well-accepted ratios or indices may not be valid for the evaluation of both genders. This study has emphasized the limiting properties for boys. This is particularly important for the selection process of some ratios and/or indices during the clinical studies. Gender difference should be taken into consideration for the evaluation of the ratios or indices, which will be recommended to be used particularly within the scope of obesity studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropometry" title="anthropometry">anthropometry</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood%20obesity" title=" childhood obesity"> childhood obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin%20sensitivity%20index" title=" insulin sensitivity index"> insulin sensitivity index</a> </p> <a href="https://publications.waset.org/abstracts/42290/laboratory-indices-in-late-childhood-obesity-the-importance-of-donma-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42290.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">356</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">36</span> Walnut (Juglans Regia) Extracts: Investigation of Antioxidant Effect, Total Phenols and Tyrosinase Inhibitory Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Saki">N.

Phenolic compounds play a number of crucial roles in complex metabolism of plants and of also fruit trees. Consumption of certain phenolics in the food is considered beneficial for human nutrition. Phenolic compounds known as anti-radical inactivators with their high antioxidant activities and these activities play an important role in inhibition of multi-metal corrosion. Many common corrosion inhibitors that are still in use today are health hazards. Therefore, there is still an increased attention directed towards the development of environmentally compatible, nonpolluting corrosion inhibitors. The present study reports the total phenols content, antioxidant potentials and tyrosinase inhibitory activity of the walnut (Juglans regia L.) produced in Turkey. The anti-tyrosinase activity was investigated for walnut at 2 h extraction time and all extracts exhibited tyrosinase activity. The results of this study suggested that walnut can be used as an excellent, easily accessible source of natural antioxidant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Juglans%20Regia" title=" Juglans Regia"> Juglans Regia</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenols" title=" total phenols"> total phenols</a>, <a href="https://publications.waset.org/abstracts/search?q=tyrosinase%20activity" title=" tyrosinase activity"> tyrosinase activity</a> </p> <a href="https://publications.waset.org/abstracts/12885/walnut-juglans-regia-extracts-investigation-of-antioxidant-effect-total-phenols-and-tyrosinase-inhibitory-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12885.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">301</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">35</span> Iterative White Balance Adjustment Process in Production Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Onder">Onur Onder</a>, <a href="https://publications.waset.org/abstracts/search?q=Celal%20Tanuca"> Celal Tanuca</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahir%20Ozil"> Mahir Ozil</a>, <a href="https://publications.waset.org/abstracts/search?q=Halil%20Sen"> Halil Sen</a>, <a href="https://publications.waset.org/abstracts/search?q=Alk%C4%B1m%20Ozkan"> Alkım Ozkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Engin%20Ceylan"> Engin Ceylan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Istek"> Ali Istek</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozgur%20Saglam"> Ozgur Saglam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> White balance adjustment of LCD TVs is an important procedure which has a direct influence on quality perception. Existing methods adjust RGB gain and offset values in different white levels during production. This paper suggests an iterative method in which the gamma is pre-adjusted during the design stage, and only 80% white is adjusted during production by modifying only RGB gain values (offset values are not modified). This method reduces the white balance adjustment time, contributing to the total efficiency of the production.

It utilizes a low electrical gradient to transport electrolytic chemical ions between bespoke electrodes inserted in the fine-grained, low permeable soft soils. The paper investigates the efficacy of the EKA as a mitigation technique for the soft clay beds. The laboratory model of the EKA comprises of rectangular plexiglass test tank, electrolytes compartments, geosynthetic electrodes and direct electric current supply. Within this setup, the EK effects resulted from the exchange of ions between anolyte (anodic) and catholyte (cathodic) ends through the tested soil were examined by basic experimental laboratory testing methods. As such, the treated soft soil properties were investigated as a function of the anode-to-cathode distances and curing periods. The test results showed that there have been some changes in the physical and engineering properties of the treated soft soils. The significant changes in the physicochemical and electrical properties suggested that their corresponding changes can be utilized as a monitoring technique to evaluate the improvement in the engineering properties EK treated soft clay soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrokinetic" title="electrokinetic">electrokinetic</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolytes" title=" electrolytes"> electrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange%20ions" title=" exchange ions"> exchange ions</a>, <a href="https://publications.waset.org/abstracts/search?q=geosynthetic%20electrodes" title=" geosynthetic electrodes"> geosynthetic electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20soils" title=" soft soils"> soft soils</a> </p> <a href="https://publications.waset.org/abstracts/49662/electrokinetic-application-for-the-improvement-of-soft-clays" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49662.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">314</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">32</span> Representation of “Gezi Parkı Actions” in Media and Resistance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sibel%20%C3%96zkan">Sibel Özkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to set forth the perception of young people in Turkey about “Gezi Parkı Actions” which has been represented by different views on social and traditional media.

All interviews has been conducted in areas where the actions take place and the numbers of participants who are using and not using social media were equal. There are minor differences between young people who are using and not using social media. Participants who are not using social media had an opinion only about saving nature aspect of Gezi Parkı Actions. On the other hand, people who are using social media had another reasons such as freedom of expression, respect to the lifestyles etc. to join Gezi Parkı Actions. It was found that young people do not completely trust traditional media anymore. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gezi%20Park%C4%B1" title="Gezi Parkı">Gezi Parkı</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=hegemony" title=" hegemony"> hegemony</a> </p> <a href="https://publications.waset.org/abstracts/12809/representation-of-gezi-parki-actions-in-media-and-resistance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12809.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">437</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">31</span> Strategic Communication in Turkish Independence War</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96zkan%20%C3%96zgen%C3%A7">Özkan Özgenç</a>, <a href="https://publications.waset.org/abstracts/search?q=Serdar%20Hacisaliho%C4%9Flu"> Serdar Hacisalihoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Yanik"> Murat Yanik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> History has shown that quantitative and qualitative supremacy in terms of military and economic power has been inadequate to reach the desired results.

Ataturk needed an impeccable communication strategy to combine efforts by establishing a united notion and action; to convince the world and Turkish nation of the legitimacy and sacredness of Independence struggle; and to show the resolution and determination of Turkish nation against the invaders. To emancipate the Turkish nation, Ataturk shaped the nation's emotions, ideas, and behaviors by using the most appropriate tools at the best time and place since the start of Independence War in May 19, 1919. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atat%C3%BCrk" title="Atatürk">Atatürk</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20independence%20struggle" title=" Turkish independence struggle"> Turkish independence struggle</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20communication" title=" strategic communication"> strategic communication</a>, <a href="https://publications.waset.org/abstracts/search?q=independence%20war" title=" independence war"> independence war</a> </p> <a href="https://publications.waset.org/abstracts/30877/strategic-communication-in-turkish-independence-war" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30877.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">293</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">30</span> Analysis of Cooperative Hybrid ARQ with Adaptive Modulation and Coding on a Correlated Fading Channel Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Ozkan">Ibrahim Ozkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a cross-layer design which combines adaptive modulation and coding (AMC) and hybrid automatic repeat request (HARQ) techniques for a cooperative wireless network is investigated analytically.

Cell blood counts may be indicators of proinflammatory states. The aim was to evaluate associations of hematological parameters, including Hematocrit (HTC), hemoglobin, blood cell counts, and their indices with the degree of obesity in pediatric population. A total of 249; -139 morbidly obese (MO), 82 healthy Normal Weight (NW) and 28 Overweight (OW) children were included into the scope of the study. WHO BMI-for age percentiles were used to form age- and sex-matched groups. Informed consent forms and the Ethics Committee approval were obtained. Anthropometric measurements were performed. Hematological parameters were determined. Statistical analyses were performed using SPSS. The degree for statistical significance was p≤0.05. Significant differences (p=0.000) between waist-to-hip ratios and head-to-neck ratios (hnrs) of MO and NW children were detected. A significant difference between hnrs of OW and MO children (p=0.000) was observed. Red cell Distribution Width (RDW) was higher in OW children than NW group (p=0.030). Such finding couldn’t be detected between MO and NW groups. Increased RDW was prominent in OW children. The decrease in Mean Corpuscular Hemoglobin Concentration (MCHC) values in MO children was sharper than the values in OW children (p=0.006 vs p=0.042) compared to those in NW group. Statistically higher HTC levels were observed between MO-NW (p=0.014), but none between OW-NW. Though the cause-effect relationship between obesity and erythrocyte indices still needs further investigation, alterations in RDW, HTC, MCHC during obesity may be of significance in the early life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropometry" title="anthropometry">anthropometry</a>, <a href="https://publications.waset.org/abstracts/search?q=children" title=" children"> children</a>, <a href="https://publications.waset.org/abstracts/search?q=erythrocytes" title=" erythrocytes"> erythrocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/30528/the-importance-of-erythrocyte-parameters-in-obese-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30528.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">352</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">28</span> An Explorative Research on the Cook and Stewards Employment: Turkish Flagged Ship's Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Yahsi">Mehmet Yahsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozkan%20Ugurlu"> Ozkan Ugurlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cabin department among the stewards and cooks on ships, has an important place in terms of a sufficient and qualified nutrition of seafarers.

The raw materials of the geopolymerization can be natural material such as kaolinite, metakaolin (calcined kaolinite), clay, diatomite, rock powder or can also be industrial by-products such as fly ash, silica fume, blast furnace slag, rice-husk ash, mine tailing, red mud, waste slag, etc. Reactivity of raw materials in geopolymer production is very important for achieving high reaction grade. Fly ash used in geopolymer production has been calcined to obtain tetrahedral SiO₂ and Al₂O₃ structures. In this study, fly ash calcined at different temperatures (700, 800 and 900 °C), and Al₂O₃ addition (Al₂O₃ at min (0%) and max (100%)) were used to produce geopolymers. HCl dissolution method was applied to determine the geopolymerization percentage of samples and Fourier Transform Infrared (FTIR) Spectroscopy was used to find out the optimum calcination temperature for geopolymerization. According to obtained results, the highest geopolymerization percentage (0% alumina added geopolymer equal to 35.789%; 100% alumina added geopolymer equal to 40.546%) was obtained in samples using fly ash calcined at 800 °C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geopolymer" title="geopolymer">geopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=Al%E2%82%82O%E2%82%83%20addition" title=" Al₂O₃ addition"> Al₂O₃ addition</a>, <a href="https://publications.waset.org/abstracts/search?q=calcination" title=" calcination"> calcination</a> </p> <a href="https://publications.waset.org/abstracts/103096/effects-of-different-calcination-temperature-on-the-geopolymerization-of-fly-ash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103096.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">176</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">25</span> An Explorative Research on the Electric and Electronic Officers Employment: Turkish Flagged Ship's Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Yahsi">Mehmet Yahsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozkan%20Ugurlu"> Ozkan Ugurlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ercan%20Yuksekyildiz"> Ercan Yuksekyildiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assistant department among the electric and electronic officers on ships, has an important place for the maintenance of electric and electronic devices.

Particle image velocimetry (PIV) technique and dye visualization experiments were performed in deep water and the flow characteristics were evaluated by means of time-averaged streamlines, Reynolds Shear Stress and Turbulent Kinetic Energy concentrations. The permeable plate was made of a chrome-nickel screen having a porosity value of β=0.6 and it was attached on the cylinder surface along its midspan. Five different angles were given to the plate (θ=0°, 15°, 30°, 45°, 60°) with respect to the centerline of the cylinder in order to examine its effect on the flow control. It was shown that the permeable plate is effective on elongating the vortex formation length and reducing the fluctuations in the wake region. Compared to the plain cylinder, the reductions in the values of maximum Reynolds shear stress and Turbulent Kinetic Energy were evaluated as 72.5% and 66%, respectively for the plate angles of θ=45° and 60° which were also found to be suggested for applications concerning the vortex shedding and consequent Vortex-Induced Vibrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bluff%20body" title="bluff body">bluff body</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20control" title=" flow control"> flow control</a>, <a href="https://publications.waset.org/abstracts/search?q=permeable%20plate" title=" permeable plate"> permeable plate</a>, <a href="https://publications.waset.org/abstracts/search?q=PIV" title=" PIV"> PIV</a>, <a href="https://publications.waset.org/abstracts/search?q=VIV" title=" VIV"> VIV</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20shedding" title=" vortex shedding"> vortex shedding</a> </p> <a href="https://publications.waset.org/abstracts/9062/flow-control-around-bluff-bodies-by-attached-permeable-plates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9062.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">360</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">23</span> Effect of Ultrasonic Treatment on the Suspension Stability, Zeta Potential and Contact Angle of Celestite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kiraz%20Esmeli">Kiraz Esmeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Ozkan"> Alper Ozkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, firstly, the effect of ultrasonic treatment on the stability of celestite suspension was investigated.

The experimental results showed that the suspension stability and zeta potential of celestite decreased with ultrasonic treatment. Also, the treatment time, immersion depth of probe, and treatment regime affected the stability of celestite suspension. Secondly, the effect of pre-treatment of the suspension with the ultrasonic process on the shear flocculation of celestite using sodium dodecyl sulfate (SDS) was studied and the variations of the flocculation, zeta potential, and contact angle of the mineral with SDS concentration were presented. It was found that the ultrasonic pre-treatment slightly improved the shear flocculation of celestite particles in accordance with the increase in the contact angles. In addition, the ultrasonic process again relatively reduced the magnitude of the negative potential of celestite particles in the presence of SDS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=celestite" title="celestite">celestite</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20angle" title=" contact angle"> contact angle</a>, <a href="https://publications.waset.org/abstracts/search?q=suspension%20stability" title=" suspension stability"> suspension stability</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20treatment" title=" ultrasonic treatment"> ultrasonic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=zeta%20potential" title=" zeta potential"> zeta potential</a> </p> <a href="https://publications.waset.org/abstracts/89475/effect-of-ultrasonic-treatment-on-the-suspension-stability-zeta-potential-and-contact-angle-of-celestite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89475.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">226</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">22</span> Effect of Particle Size on Sintering Characteristics of Injection Molded 316L Powder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20%C3%96zkan%20G%C3%BClsoy">H.

The aim of this study is to establish the potential link between these diseases and CD4+, CD25+ FoxP3+ Tregs as well as T helper cells (Ths) in children. This is a prospective case control study. Obese (n:40), asthmatic (n:40), asthmatic obese (n:40), and healthy children (n:40), who don't have any acute or chronic diseases, were included in this study. Obese children were evaluated according to WHO criteria. Asthmatic patients were chosen based on GINA criteria. Parents were asked to fill up the questionnaire. Informed consent forms were taken. Blood samples were marked with CD4+, CD25+ and FoxP3+ in order to determine Tregs and Ths by flow cytometric method. Statistical analyses were performed. p≤0.05 was chosen as meaningful threshold. Tregs exhibiting anti-inflammatory nature were significantly lower in obese (0,16%; p≤0,001), asthmatic (0,25%; p≤0,01) and asthmatic obese (0,29%; p≤0,05) groups than the control group (0,38%). Ths were counted higher in asthma group than the control (p≤0,01) and obese (p≤0,001)) groups. T cell immunity plays important roles in obesity and asthma pathogeneses. Decreased numbers of Tregs found in obese, asthmatic and asthmatic obese children may help to elucidate some questions in pathophysiology of these diseases. For HOMA-IR levels, any significant difference was not noted between control and obese groups, but statistically higher values were found for obese asthmatics. The values obtained in all groups were found to be below the critical cut off points. This finding has made the statistically significant difference observed between Tregs of obese, asthmatic, obese asthmatic, and control groups much more valuable. These findings will be useful in diagnosis and treatment of these disorders and future studies are needed. The production and propagation of Tregs may be promising in alternative asthma and obesity treatments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asthma" title="asthma">asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20cytometry" title=" flow cytometry"> flow cytometry</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20obesity" title=" pediatric obesity"> pediatric obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=T%20cells" title=" T cells "> T cells </a> </p> <a href="https://publications.waset.org/abstracts/30529/t-cell-immunity-profile-in-pediatric-obesity-and-asthma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30529.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">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Finite Element Method Analysis of a Modified Rotor 6/4 Switched Reluctance Motor's and Comparison with Brushless Direct Current Motor in Pan-Tilt Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umit%20Candan">Umit Candan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kadir%20Dogan"> Kadir Dogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozkan%20Akin"> Ozkan Akin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the use of a modified rotor 6/4 Switched Reluctance Motor (SRM) and a Brushless Direct Current Motor (BLDC) in pan-tilt systems is compared. Pan-tilt systems are critical mechanisms that enable the precise orientation of cameras and sensors, and their performance largely depends on the characteristics of the motors used. The aim of the study is to determine how the performance of the SRM can be improved through rotor modifications and how these improvements can compete with BLDC motors. Using Finite Element Method (FEM) analyses, the design characteristics and magnetic performance of the 6/4 Switched Reluctance Motor are examined in detail. The modified SRM is found to offer increased torque capacity and efficiency while standing out with its simple construction and robustness. FEM analysis results of SRM indicate that considering its cost-effectiveness and performance improvements achieved through modifications, the SRM is a strong alternative for certain pan-tilt applications. This study aims to provide engineers and researchers with a performance comparison of the modified rotor 6/4 SRM and BLDC motors in pan-tilt systems, helping them make more informed and effective motor selections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reluctance%20machines" title="reluctance machines">reluctance machines</a>, <a href="https://publications.waset.org/abstracts/search?q=switched%20reluctance%20machines" title=" switched reluctance machines"> switched reluctance machines</a>, <a href="https://publications.waset.org/abstracts/search?q=pan-tilt%20application" title=" pan-tilt application"> pan-tilt application</a>, <a href="https://publications.waset.org/abstracts/search?q=comparison" title=" comparison"> comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM%20analysis" title=" FEM analysis"> FEM analysis</a> </p> <a href="https://publications.waset.org/abstracts/186393/finite-element-method-analysis-of-a-modified-rotor-64-switched-reluctance-motors-and-comparison-with-brushless-direct-current-motor-in-pan-tilt-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186393.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">58</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Discovering the Effects of Guerrilla Advertisements on Perceiver's Ad Attitude, Ad Likability and Purchase Intention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Y.%20Ozkan">S.

Participants who were over 18 years of age were recruited and completed an online questionnaire. Each participant was randomly assigned to one of the four well-known brand conditions. The study had a within-subjects design where each participant evaluated two advertisements, one guerrilla advertisement, and one traditional advertisement od one respective brand. Participants rated both traditional advertisement and guerrilla advertisement on ad attitude, ad likability, and purchase intention scales. Ad attitude was measured by using both positive and negative adjectives. The hypotheses were tested by paired samples t-test analysis. The results indicated that perceivers were able to differentiate advertisements that include guerrilla techniques and advertisements that include traditional methods from one another. Regardless of the brand manipulation, guerrilla advertisements lead significantly higher positive ad attitude, negative ad attitude, ad likability, and purchase intention compared to traditional advertisements. Therefore, the results showed that while using guerrilla advertising, companies should be aware of any ethical concerns that may emerge in consumers' minds. Present study is one of the rare studies that measures the perceptions of guerrilla and traditional advertisements in an empirical manner in Turkish context, showing that guerrilla advertisements may stimulate negative ad attitudes together with positive ad attitudes, increasing ad likability and purchase intention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ad%20attitude" title="ad attitude">ad attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=guerrilla%20advertisement" title=" guerrilla advertisement"> guerrilla advertisement</a>, <a href="https://publications.waset.org/abstracts/search?q=purchase%20intention" title=" purchase intention"> purchase intention</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20advertisement" title=" traditional advertisement"> traditional advertisement</a> </p> <a href="https://publications.waset.org/abstracts/126009/discovering-the-effects-of-guerrilla-advertisements-on-perceivers-ad-attitude-ad-likability-and-purchase-intention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126009.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">139</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> Settlement Analysis of Axially Loaded Bored Piles: A Case History</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Mert">M.

Strain gauges can be installed into pile in order to determine the shaft resistance of the piles for every soil layer respectively. Detailed results can be obtained by means of strain gauges placed at certain levels into test piles. In the scope of this study, pile load test data obtained from two different projects are examined.  Instrumented static pile load tests were applied on totally 7 test bored piles of different diameters (80 cm, 150 cm, and 200 cm) and different lengths (between 30-76 m) in two different project site. Settlement analysis of test piles is done by using some of load transfer methods and finite element method. Plaxis 3D which is a three-dimensional finite element program is also used for settlement analysis of the test piles. In this study, firstly bearing capacity of test piles are determined and compared with strain gauge data which is required for settlement analysis. Then, settlement values of the test piles are estimated by using load transfer methods developed in recent years and finite element method. The aim of this study is to show similarities and differences between the results obtained from settlement analysis methods and instrumented pile load tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=failure" title="failure">failure</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20and%20instrumentation" title=" monitoring and instrumentation"> monitoring and instrumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=pile" title=" pile"> pile</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement" title=" settlement"> settlement</a> </p> <a href="https://publications.waset.org/abstracts/103165/settlement-analysis-of-axially-loaded-bored-piles-a-case-history" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103165.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">167</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> Naturalization of Aliens in Consideration of Turkish Constitutional Law: Recent Governmental Practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Ozkan">Zeynep Ozkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Cigdem%20Serra%20Uzunpinar"> Cigdem Serra Uzunpinar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Citizenship is a legal bond that binds a person to a certain state. How constitutions define ‘the citizen’ and how they regulate the elements of citizenship have great importance in terms of individuals’ duties before the state as well as the rights they own. Especially in multi-segmented societies that contain foreign elements, it becomes necessary to examinate the institution of naturalization in terms of individuals’ duty of constitutional citizenship. The meaning of citizenship in Turkey has transformed due to the changes in practices of naturalization, in parallel to receiving huge amount of immagrants with the recent Syrian Crisis, the change in the governmental system and facing economic crisis. This transformation took place in the way of a diversion from the states’ initial motive of building the bond of citizenship with the aim of founding/sustaining political unity. Hence, rising of the economic and political motives in naturalization practices are in question, instead of objective and subjective criterias, that are traditionally used on defining the notion of nation. In this study, firstly the regime of citizenship and the legal regime of aliens in Turkish legislation will be given place. Then, the transformation, that the notion of constitutional citizenship underwent, will be studied, especially on the basis of governmental practices of naturalization. The assessment will be made in the context of legal institutions brought with the new governmental system as a result of recent constitutional amendment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constitutional%20citizenship" title="constitutional citizenship">constitutional citizenship</a>, <a href="https://publications.waset.org/abstracts/search?q=naturalization" title=" naturalization"> naturalization</a>, <a href="https://publications.waset.org/abstracts/search?q=naturalization%20practices%20in%20Turkish%20legal%20system" title=" naturalization practices in Turkish legal system"> naturalization practices in Turkish legal system</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation%20of%20the%20notion%20of%20constitutional%20citizenship" title=" transformation of the notion of constitutional citizenship"> transformation of the notion of constitutional citizenship</a> </p> <a href="https://publications.waset.org/abstracts/107227/naturalization-of-aliens-in-consideration-of-turkish-constitutional-law-recent-governmental-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107227.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">118</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> Mathematical Modelling of Ultrasound Pre-Treatment in Microwave Dried Strawberry (Fragaria L.)

Then mathematical modelling was applied to dried fruits by using different experimental thin layer models. The sliced fruits were subjected to ultrasound treatment at a frequency of 40 kHz for 10, 20, and 30 minutes, in an ultrasonic water bath, with a ratio of 1:4 to fruit/water. They are then dried in the microwave (90W). The drying process continued until the product moisture was below 10%. By analyzing the moisture change of the products at a certain time, eight different thin-layer drying models, (Newton, page, modified page, Midilli, Henderson and Pabis, logarithmic, two-term, Wang and Singh) were tested for verification of experimental data. MATLAB R2015a statistical program was used for the modelling, and the best suitable model was determined with R²adj (coefficient of determination of compatibility), and root mean square error (RMSE) values. According to analysis, the drying model that best describes the drying behavior for both drying conditions was determined as the Midilli model by high R²adj and low RMSE values. Control, 10, 20, and 30 min US for groups R²adj and RMSE values was established as respectively; 0,9997- 0,005298; 0,9998- 0,004735; 0,9995- 0,007031; 0,9917-0,02773.

In this study, the objective is to investigate the influence of particle size distribution on mechanical strength and physical properties of the engineered stone slabs. For this purpose, granular quartz with two particle size ranges of 63-200 µm and 100-300 µm were used individually and mixed with a difference in ratios of mixing. The void volume of each granular packing was measured in order to define the amount of filler; quartz powder with the size of less than 38 µm, and UPR required filling inter-particle spaces. Test slabs were prepared using vibration-compression under vacuum. The study reports that both impact strength and flexural strength of samples increased as the mix ratio of the particle size range of 63-200 µm increased. On the other hand, the values of water absorption rate, apparent density and abrasion resistance were not affected by the particle size distribution owing to vacuum compaction. It is found that increasing the mix ratio of the particle size range of 63-200 µm caused the higher porosity. This led to increasing in the amount of the binder paste needed. It is also observed that homogeneity in the slabs was improved with the particle size range of 63-200 µm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineered%20quartz%20stone" title="engineered quartz stone">engineered quartz stone</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20quartz%20aggregate" title=" fine quartz aggregate"> fine quartz aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=granular%20packing" title=" granular packing"> granular packing</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20strength" title=" mechanical strength"> mechanical strength</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20distribution" title=" particle size distribution"> particle size distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20properties." title=" physical properties."> physical properties.</a> </p> <a href="https://publications.waset.org/abstracts/110565/effects-of-particle-size-distribution-on-mechanical-strength-and-physical-properties-in-engineered-quartz-stone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110565.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> A Comparative Study of Single- and Multi-Walled Carbon Nanotube Incorporation to Indium Tin Oxide Electrodes for Solar Cells </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Gokceli">G.

Since indium tin oxide (ITO) is the most preferred transparent conductive electrode, producing ITO films by simple and cost-effective solution-based techniques with enhanced optical and electrical properties has great importance. In this study, single- and multi-walled carbon nanotubes (SWCNT and MWCNT) incorporated into the ITO structure to increase electrical conductivity, mechanical strength, and chemical stability. Carbon nanotubes (CNTs) were firstly functionalized by acid treatment (HNO<sub>3</sub>:H<sub>2</sub>SO<sub>4</sub>), and the thermal resistance of CNTs after functionalization was determined by thermogravimetric analysis (TGA). Thin films were then prepared by spin coating technique and characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), four-point probe measurement system and UV-Vis spectrophotometer. The effects of process parameters were compared for ITO, MWCNT-ITO, and SWCNT-ITO films. Two factors including CNT concentration and annealing temperature were considered. The UV-Vis measurements demonstrated that the transmittance of ITO films was 83.58% at 550 nm, which was decreased depending on the concentration of CNT dopant. On the other hand, both CNT dopants provided an enhancement in the crystalline structure and electrical conductivity. Due to compatible diameter and better dispersibility of SWCNTs in the ITO solution, the best result in terms of electrical conductivity was obtained by SWCNT-ITO films with the 0.1 g/L SWCNT dopant concentration and heat-treatment at 550 °C for 1 hour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CNT%20incorporation" title="CNT incorporation">CNT incorporation</a>, <a href="https://publications.waset.org/abstracts/search?q=ITO%20electrode" title=" ITO electrode"> ITO electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=spin%20coating" title=" spin coating"> spin coating</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a> </p> <a href="https://publications.waset.org/abstracts/101020/a-comparative-study-of-single-and-multi-walled-carbon-nanotube-incorporation-to-indium-tin-oxide-electrodes-for-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101020.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">115</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> Implications of Industry 4.0 to Supply Chain Management and Human Resources Management: The State of the Art</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayse%20Begum%20Kilic">Ayse Begum Kilic</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevgi%20Ozkan"> Sevgi Ozkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Industry 4.0 (I4.0) is a significant and promising research topic that is expected to gain more importance due to its effects on important concepts like cost, resource management, and accessibility. Instead of focusing those effects in only one area, combining different departments, and see the big picture helps to make more realistic predictions about the future. The aim of this paper is to identify the implications of Industry 4.0 for both supply chain management and human resources management by finding out the topics that take place at the intersection of them. Another objective is helping the readers to realize the expected changes in these two areas due to I4.0 in order to take the necessary steps in advance and make recommendations to catch up the latest trends. The expected changes are concluded from the industry reports and related journal papers in the literature. As found in the literature, this study is the first to combine the Industry 4.0, supply chain management and human resources management and urges to lead future works by finding out the intersections of those three areas. Benefits of I4.0 and the amount, research areas and the publication years of papers on I4.0 in the academic journals are mentioned in this paper. One of the main findings of this research is that a change in the labor force qualifications is expected with the advancements in the technology. There will be a need for higher level of skills from the workers. This will directly affect the human resources management in a way of recruiting and managing those people. Another main finding is, as it is explained with an example in the article, the advancements in the technology will change the place of production. For instance, 'dark factories', a popular topic of I4.0, will enable manufacturers to produce in places that close to their marketplace. The supply chains are expected to be influenced by that change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20resources%20management" title="human resources management">human resources management</a>, <a href="https://publications.waset.org/abstracts/search?q=industry%204.0" title=" industry 4.0"> industry 4.0</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics" title=" logistics"> logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/85979/implications-of-industry-40-to-supply-chain-management-and-human-resources-management-the-state-of-the-art" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85979.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">12</span> An Investigation of Item Bias in Free Boarding and Scholarship Examination in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ye%C5%9Fim%20%C3%96zer%20%C3%96zkan">Yeşim Özer Özkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20B%C3%BC%C5%9Fra%20Fincan"> Fatma Büşra Fincan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biased sample is a regression of an observation, design process and all of the specifications lead to tendency of a side or the situation of leaving from the objectivity. It is expected that, test items are answered by the students who come from different social groups and the same ability not to be different from each other. The importance of the expectation increases especially during student selection and placement examinations. For example, all of the test items should not be beneficial for just a male or female group. The aim of the research is an investigation of item bias whether or not the exam included in 2014 free boarding and scholarship examination in terms of gender variable. Data which belong to 5th, 6th, and 7th grade the secondary education students were obtained by the General Directorate of Measurement, Evaluation and Examination Services in Turkey. 20% students were selected randomly within 192090 students. Based on 38418 students’ exam paper were examined for determination item bias. Winsteps 3.8.1 package program was used to determine bias in analysis of data, according to Rasch Model in respect to gender variable. Mathematics items tests were examined in terms of gender bias. Firstly, confirmatory factor analysis was applied twenty-five math questions. After that, NFI, TLI, CFI, IFI, RFI, GFI, RMSEA, and SRMR were examined in order to be validity and values of goodness of fit. Modification index values of confirmatory factor analysis were examined and then some of the items were omitted because these items gave an error in terms of model conformity and conceptual. The analysis shows that in 2014 free boarding and scholarship examination exam does not include bias. This is an indication of the gender of the examination to be made in favor of or against different groups of students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=item%20bias" title=" item bias"> item bias</a>, <a href="https://publications.waset.org/abstracts/search?q=placement%20test" title=" placement test"> placement test</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasch%20model" title=" Rasch model"> Rasch model</a> </p> <a href="https://publications.waset.org/abstracts/48816/an-investigation-of-item-bias-in-free-boarding-and-scholarship-examination-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48816.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">230</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> Performance Measurement by Analytic Hierarchy Process in Performance Based Logistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Hilmi%20Ozdemir">M. Hilmi Ozdemir</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Ozkan"> Gokhan Ozkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Performance Based Logistics (PBL) is a strategic approach that enables creating long-term and win-win relations among stakeholders in the acquisition. Contrary to the traditional single transactions, the expected value is created by the performance of the service pertaining to the strategic relationships in this approach. PBL motivates all relevant stakeholders to focus on their core competencies to produce the desired outcome in a collective way. The desired outcome can only be assured with a cost effective way as long as it is periodically measured with the right performance parameters. Thus, defining these parameters is a crucial step for the PBL contracts. In performance parameter determination, Analytic Hierarchy Process (AHP), which is a multi-criteria decision making methodology for complex cases, was used within this study for a complex system. AHP has been extensively applied in various areas including supply chain, inventory management, outsourcing, and logistics. This methodology made it possible to convert end-user’s main operation and maintenance requirements to sub criteria contained by a single performance parameter. Those requirements were categorized and assigned weights by the relevant stakeholders. Single performance parameter capable of measuring the overall performance of a complex system is the major outcome of this study. The parameter deals with the integrated assessment of different functions spanning from training, operation, maintenance, reporting, and documentation that are implemented within a complex system. The aim of this study is to show the methodology and processes implemented to identify a single performance parameter for measuring the whole performance of a complex system within a PBL contract. AHP methodology is recommended as an option for the researches and the practitioners who seek for a lean and integrated approach for performance assessment within PBL contracts. The implementation of AHP methodology in this study may help PBL practitioners from methodological perception and add value to AHP in becoming prevalent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytic%20hierarchy%20process" title="analytic hierarchy process">analytic hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20based%20logistics" title=" performance based logistics"> performance based logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20measurement" title=" performance measurement"> performance measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20parameters" title=" performance parameters"> performance parameters</a> </p> <a href="https://publications.waset.org/abstracts/63265/performance-measurement-by-analytic-hierarchy-process-in-performance-based-logistics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63265.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">281</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> A New Binder Mineral for Cement Stabilized Road Pavements Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayd%C4%B1n%20Kavak">Aydın Kavak</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zkan%20Coruk"> Özkan Coruk</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Ayd%C4%B1ner"> Adnan Aydıner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Long-term performance of pavement structures is significantly impacted by the stability of the underlying soils. In situ subgrades often do not provide enough support required to achieve acceptable performance under traffic loading and environmental demands. NovoCrete® is a powder binder-mineral for cement stabilized road pavements soils. NovoCrete® combined with Portland cement at optimum water content increases the crystallize formations during the hydration process, resulting in higher strengths, neutralizes pH levels, and provides water impermeability. These changes in soil properties may lead to transforming existing unsuitable in-situ materials into suitable fill materials. The main features of NovoCrete® are: They are applicable to all types of soil, reduce premature cracking and improve soil properties, creating base and subbase course layers with high bearing capacity by reducing hazardous materials. It can be used also for stabilization of recyclable aggregates and old asphalt pavement aggregate, etc. There are many applications in Germany, Turkey, India etc. In this paper, a few field application in Turkey will be discussed. In the road construction works, this binder material is used for cement stabilization works. In the applications 120-180 kg cement is used for 1 m3 of soil with a 2 % of binder NovoCrete® material for the stabilization. The results of a plate loading test in a road construction site show 1 mm deformation which is very small under 7 kg/cm2 loading. The modulus of subgrade reaction increase from 611 MN/m3 to 3673 MN/m3.The soaked CBR values for stabilized soils increase from 10-20 % to 150-200 %. According to these data weak subgrade soil can be used as a base or sub base after the modification. The potential reduction in the need for quarried materials will help conserve natural resources. The use of on-site or nearby materials in fills, will significantly reduce transportation costs and provide both economic and environmental benefits. <p class="card-text"><strong>Keywords:</strong> <a
