genetic disorder caused by the presence of all or part of an extra chromosome 21. Many patients with DS have musculoskeletal problems that affect weak muscle tone (hypotonia) and ligament laxity. This leads to excessive joint hypermobility and decreased position sense (proprioception). Lack of proprioception may cause balance problems. The aim of our study was to investigate how does joint hypermobility affect balance in patients with DS. Our study conducted with 13 DS patients age between 18 to 40 years. Demographic data were recorded. Beighton Hypermobility Score (BHS) was used to evaluate joint hypermobility. Balance score of participants was evaluated with Berg Balance Scale (BBS). Mean age of our participants was 29,8±3,57 year. Average score of body mass index and BHS were; 33,23 ±3,78 kg/m2 and 7,61±1,04, respectively. Out of a maximum possible score of 56 on the Berg Balance Scale, scores of participants with DS ranged from 36–51, with a mean of 43±4,45. Significant correlation was found between BHS and BBS (r: -,966, p=0.00). All of our participants have 6/9 or higher grade from BHS. As a conclusion of our study; joint hypermobility may affect balance score in patients with DS. The results suggest that people with DS have worse balance scores which affected by hypermobility. Further studies need larger population for more reliable results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adults" title="adults">adults</a>, <a href="https://publications.waset.org/abstracts/search?q=balance" title=" balance"> balance</a>, <a href="https://publications.waset.org/abstracts/search?q=Down%27s%20syndrome" title=" Down's syndrome"> Down's syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20hypermobility" title=" joint hypermobility"> joint hypermobility</a> </p> <a href="https://publications.waset.org/abstracts/68798/relationship-between-joint-hypermobility-and-balance-in-patients-with-downs-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68798.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">31</span> Biological Activities of Gentiana brachyphylla Vill.

Chenopodium species are traditionally used to treat chest and abdominal pain, shortness of breath, cough and neurological disorders. Chenopodium quinoa Willd. (Quinoa) is native to Andes region of South America (especially Peru and Bolivia) and cultivated in many countries include also Turkey in the world nowadays. The seeds of quinoa are rich in protein, and the phytochemical composition consists of antioxidant substances such as polyphenolic compounds, flavonoids, vitamins, and minerals; anticancer and neuroprotective compounds such as tocotrienols; anti-inflammatory compounds such as carotenoids and anthocyanins and also saponins and starch. Food products of quinoa such as quinoa cereal bar, pasta and cornflakes are used in the diet made during many disorders like obesity, cardiovascular disorder, hypertension and Celiac disease. Also quinoa seems to have antimicrobial, anti-inflammatory and cholesterol-lowering properties because of its bioactive compounds. In this present study, the aqueous ethanolic extracts of the seeds of three different coloured genotypes of quinoa were investigated for their antioxidant activities using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, ferrous ion-chelating effect, ferric-reducing antioxidant power, ABTS radical cation decolorization assays and total phenolic contents using Folin-Ciocalteu assay. Among the three genotypes of quinoa; the aqueous ethanolic extract of the red genotype had the highest total phenolic content (83.54 ± 2.12 mg gallic acid/100 g extract) whereas the extract of the white genotype had the lowest total phenolic content (70.66 ± 0.25 mg gallic acid/100 g). According to the antioxidant activity results; the extracts showed moderate reducing power effect whereas weak ABTS radical cation decolorization and ferrous ion-chelating effect and also too weak DPPH radical scavenging activity when compared to the positive standards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amaranthaceae" title="amaranthaceae">amaranthaceae</a>, <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=Chenopodium%20quinoa%20willd." title=" Chenopodium quinoa willd."> Chenopodium quinoa willd.</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenolic%20content" title=" total phenolic content"> total phenolic content</a> </p> <a href="https://publications.waset.org/abstracts/81657/determination-of-phenolic-contents-and-antioxidant-activities-of-chenopodium-quinoa-willd-seed-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81657.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">180</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">29</span> Electromechanical Behaviour of Chitosan Based Electroactive Polymer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Sarikanat">M.

One of the major setbacks of the models used in the scientific community is the lack of regard to the different phases present in a nanocomposite. We employ a multi-phase micromechanical model that allows functionally grading certain phases to determine the mechanical properties of nanocomposites. The model has four distinct phases; the nanotube, the interface between the nanotube and polymer, the interphase, and the bulk matrix. Among the four phases, the interphase is functionally graded such that its moduli gradually decrease from some predetermined values to those of the bulk polymer. We find that the interface plays little role in stiffening/softening of the polymer per se , but instead, it is responsible for load transfer between the polymer and the carbon nanotube. Our results indicate that the carbon nanotube, as well as the interphase, have significant roles in stiffening the composite. The results are then compared to experimental findings and the interphase is tuned accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title="carbon nanotube">carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=interphase" title=" interphase"> interphase</a>, <a href="https://publications.waset.org/abstracts/search?q=micromechanical%20modeling" title=" micromechanical modeling"> micromechanical modeling</a> </p> <a href="https://publications.waset.org/abstracts/93783/micromechanical-determination-of-the-mechanical-properties-of-carbon-nanotube-polymer-composites-with-a-functionally-graded-interphase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93783.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">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Corruption and Income: Case of Independent Turkish Republic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahime%20H%C3%BClya%20%20%C3%96zt%C3%BCrk">Rahime Hülya Öztürk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Along with the development of globalization, the relationship between economic, politic and commercial behaviors became unlimited. The liberalization of capital has many advantages for countries, but it also has some disadvantages. In these disadvantages the most important one is corruption. Especially in Developing Countries and Underdeveloped countries, corruption is very extensive. Corruption causes inefficient use of resources and promotes income inequality. Especially in the transition period of economies corruption increases and sometimes governments don’t interfere. To fight against corruption domestic and international measures are taken. Corruption is an economic problem, but it also has social and moral effects. The aim of this study is to define the relationship between corruption and income in Independent Turkish State. In the first part of the study, the concept of corruption is examined. In the second part of the study, information about The Independent Turkish Republic is given. In the third part of the study, country’s relationship between corruption and income is analyzed with panel data analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corruption" title="corruption">corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=income" title=" income"> income</a>, <a href="https://publications.waset.org/abstracts/search?q=independent%20Turkish%20Republic" title=" independent Turkish Republic"> independent Turkish Republic</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20of%20income" title=" distribution of income"> distribution of income</a> </p> <a href="https://publications.waset.org/abstracts/52431/corruption-and-income-case-of-independent-turkish-republic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52431.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">315</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> Copolymers of Pyrrole and α,ω-Dithienyl Terminated Poly(ethylene glycol)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nesrin%20K%C3%B6ken">Nesrin Köken</a>, <a href="https://publications.waset.org/abstracts/search?q=Esin%20A.%20G%C3%BCvel"> Esin A.

It has been seen that cross-sectional appearance of sample with ACP is harsh and porous because of ACP. The addition of ACP did not change the electrical conductivity. However, ACP results in an enormous decrease of mechanical properties. Longer exfoliation time results to higher crystallinity degree, C/O ratio and less d space between layers.

The investigation of change of the tensile properties of organoclay/linear low density polyethylene (LLDPE) nanocomposites with the use of Dioctyl terephthalate (DOTP) (as plasticizer) and calcite (as filler) has been aimed. The composites and organoclay synthesized were characterized using the techniques such as XRD, HRTEM and FTIR techniques. The spectroscopic results indicate that platelets of organoclay were well dispersed within the polymeric matrix. The tensile properties of the composites were compared considering the stress-strain curve drawn for each composite and pure polymer. It was observed that the composites prepared by adding the plasticizer at different ratios and a certain amount of calcite exhibited different tensile behaviors compared to pure polymer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=linear%20low%20density%20polyethylene" title="linear low density polyethylene">linear low density polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=organoclay" title=" organoclay"> organoclay</a>, <a href="https://publications.waset.org/abstracts/search?q=plasticizer" title=" plasticizer"> plasticizer</a> </p> <a href="https://publications.waset.org/abstracts/53070/the-effect-of-addition-of-dioctyl-terephthalate-and-calcite-on-the-tensile-properties-of-organoclaylinear-low-density-polyethylene-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53070.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">20</span> Rheological Properties of Polysulfone-Sepiolite Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilay%20Tanr%C4%B1ver">Nilay Tanrıver</a>, <a href="https://publications.waset.org/abstracts/search?q=Birg%C3%BCl%20Benli"> Birgül Benli</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilg%C3%BCn%20K%C4%B1z%C4%B1lcan"> Nilgün Kızılcan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polysulfone (PSU) is a specialty engineering polymer having various industrial applications. PSU is especially used in waste water treatment membranes due to its good mechanical properties, structural and chemical stability. But it is a hydrophobic material and therefore its surface aim to pollute easily. In order to resolve this problem and extend the properties of membrane, PSU surface is rendered hydrophilic by addition of the sepiolite nanofibers. Sepiolite is one of the natural clays, which is a hydrate magnesium silicate fiber, also one of the well known layered clays of the montmorillonites where has several unique channels and pores within. It has also moisture durability, strength and low price. Sepiolite channels give great capacity of absorption and good surface properties. In this study, nanocomposites of commercial PSU and Sepiolite were prepared by solvent mixing method. Different organic solvents and their mixtures were used. Rheological characteristics of PSU-Sepiolite solvent mixtures were analyzed, the solubility of nanocomposite content in those mixtures were studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title="nanocomposite">nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=polysulfone" title=" polysulfone"> polysulfone</a>, <a href="https://publications.waset.org/abstracts/search?q=rheology" title=" rheology"> rheology</a>, <a href="https://publications.waset.org/abstracts/search?q=sepiolite" title=" sepiolite"> sepiolite</a>, <a href="https://publications.waset.org/abstracts/search?q=solution%20mixing" title=" solution mixing"> solution mixing</a> </p> <a href="https://publications.waset.org/abstracts/23499/rheological-properties-of-polysulfone-sepiolite-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23499.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">424</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> GaAs Based Solar Cells: Growth, Fabrication, and Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H%C3%BClya%20Kuru%20Mutlu">Hülya Kuru Mutlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Kulakc%C4%B1"> Mustafa Kulakcı</a>, <a href="https://publications.waset.org/abstracts/search?q=U%C4%9Fur%20Serincan"> Uğur Serincan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The sun is one of the latest developments in renewable energy sources, which has a variety of application. Solar energy is the most preferred renewable energy sources because it can be used directly, it protects the environment and it is economic. In this work, we investigated that important parameter of GaAs-based solar cells with respect to the growth temperature. The samples were grown on (100) oriented p-GaAs substrates by solid source Veeco GEN20MC MBE system equipped with Ga, In, Al, Si, Be effusion cells and an Arsenic cracker cell. The structures of the grown samples are presented. After initial oxide desorption, Sample 1 and Sample 2 were grown at about 585°C and 535°C, respectively. From the grown structures, devices were fabricated by using the standard photolithography procedure. Current-voltage measurements were performed at room temperature (RT). It is observed that Sample 1 which was grown at 585°C has higher efficiency and fill factor compared to Sample 2. Hence, it is concluded that the growth temperature of 585°C is more suitable to grow GaAs-based solar cells considering our samples used in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molecular%20beam%20epitaxy" title="molecular beam epitaxy">molecular beam epitaxy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title=" solar cell"> solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=current-voltage%20measurement" title=" current-voltage measurement"> current-voltage measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun" title=" Sun"> Sun</a> </p> <a href="https://publications.waset.org/abstracts/32490/gaas-based-solar-cells-growth-fabrication-and-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32490.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">473</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> An Analysis on Fibre-Reinforced Composite Material Usage on Urban Furniture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilgun%20Becenen">Nilgun Becenen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the structural properties of composite materials with the plastic matrix, which are used in body parts of urban furniture were investigated.

In that case, ENP acted as an organic reducing agent in the presence of Ce (IV) salt and a radical was formed. The polymers obtained with that redox system contained ENP chain ends because the radicals are formed on the reducing molecules. Similar copolymer synthesis has been reported using poly(ethylene oxide) instead of its nonyl phenol terminated derivative, ENP. However, copolymers of poly(ethylene oxide) and conducting polymers synthesized by ferric ions were produced in two steps. Firstly, heteroatoms (pyrrole, thiophene etc.) were attached to the poly(ethylene oxide) chains then copolymerization with heterocyclic monomers was carried out. In this work, ethoxylated nonylphenol (ENP) was reacted with 2-thiophenecarbonyl chloride in order to synthesize a macromonomer containing thienyl end-group (ENP-ThC). Then, copolymers of ENP-ThC and pyrrole were synthesized by chemical oxidative polymerization using iron (III) chloride as an oxidant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=end%20capped%20polymer" title="end capped polymer">end capped polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=ethoxylated%20nonylphenol" title=" ethoxylated nonylphenol"> ethoxylated nonylphenol</a>, <a href="https://publications.waset.org/abstracts/search?q=heterophase%20polymerization" title=" heterophase polymerization"> heterophase polymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=polypyrrole" title=" polypyrrole"> polypyrrole</a> </p> <a href="https://publications.waset.org/abstracts/20937/heterophase-polymerization-of-pyrrole-and-thienyl-end-capped-ethoxylated-nonyl-phenol-by-iron-iii-chloride" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20937.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">407</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> Si3N4-SiC Composites Produced by Using C Black and Sic Powder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilgun%20Kuskonmaz">Nilgun Kuskonmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Tasl%C4%B1cukur%20Ozturk"> Zeynep Taslıcukur Ozturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Cem%20Sahin"> Cem Sahin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, Si3N4-SiC composites were synthesized by using different raw materials. In the first method, Si3N4 and C black powder mixtures were used to fabricate Si3N4-SiC composites by in-situ carbothermal reduction process. The percentage of C black was only changed. The effects of carbon black percentage in the mixtures were analysed by characterization of SiC particles which were obtained in the Si3N4 matrix. In the second method, SiC particles were added to the matrix in different weight ratios. The composites were pressed by cold isostatic method under 150 MPa pressure and pressureless sintered at 1700-1850 °C during 1 hour in the argon atmosphere. AlN and Y2O3 were used as sintering additives. Sintering temperature, time and all the effects on in-situ reaction were studied. The densification and microstructure properties of the produced ceramics were analysed. Density was one of the main subjects in these reactions. It is very important during porous SiC sintering. Green density and relative density were measured higher for CIP samples. Samples which were added carbon black were more porous than SiC added samples. The increase in the carbon black, makes increase in porosity. The outcome of the experiments was SiC powders which were obtained at the grain boundries of β-Si3N4 particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silicon%20nitride" title="silicon nitride">silicon nitride</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20carbide" title=" silicon carbide"> silicon carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20black" title=" carbon black"> carbon black</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20isostatic%20press" title=" cold isostatic press"> cold isostatic press</a>, <a href="https://publications.waset.org/abstracts/search?q=sintering" title=" sintering"> sintering</a> </p> <a href="https://publications.waset.org/abstracts/41249/si3n4-sic-composites-produced-by-using-c-black-and-sic-powder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41249.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">309</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> Changes in Inorganic Element Contents in Potamogeton Natans Exposed to Cement Factory Pollution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yavuz%20Demir">Yavuz Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mucip%20Genisel"> Mucip Genisel</a>, <a href="https://publications.waset.org/abstracts/search?q=Hulya%20Turk"> Hulya Turk</a>, <a href="https://publications.waset.org/abstracts/search?q=Turgay%20Sisman"> Turgay Sisman</a>, <a href="https://publications.waset.org/abstracts/search?q=Serkan%20Erdal"> Serkan Erdal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the changes in contents of inorganic elements in the aquatic plant (Potamogeton natans) as a reflection of the impact of chemical nature pollution in a cement factory region (CFR) was evaluated. For this purpose, P, S, K, Ca, Fe, Cl, Mn, Cu, Zn, Mo, Ni, Si, Al, and Cd concentrations were measured in the aquatic plant (Potamogeton natans) taken from a CFR. As a control, aquatic plant was collected at a distance of 2000 m from the outer zone of the cement factory. Inorganic element compositions were measured by energy dispersive X-ray fluorescence spectrometry (EDXRF). Three aquatic plant exhibited similar changes in contents of microelements and macroelements in their leaves. P, S, K, Cl, Ca, and Mo contents in plant grown in the CFR were reduced significantly compared to control plant, whereas their contents of Al, Mn, Fe, Ni, Cu, Zn and Cd were very high. According to these findings, it is possible that aquatic plant (Potamogeton natans) inhabiting in the vicinity of cement factory sustains the deficiency of important essential elements like P, S, K, Ca, and Mo and greatly accumulate heavy metals like Al, Mn, Fe, Ni, Cu, Zn, and Cd. In addition, results of water analysis showed that heavy metal content such as Cu, Pb, Zn, Co, and Al of water taken from CFR was remarkably high than that of outer zone of CFR. These findings with relation to changes in inorganic composition can contribute to be elucidated of effect mechanism on growth and development of aquatic plant (Potamogeton natans) of pollution resulted from cement factories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquatic%20plant" title="aquatic plant">aquatic plant</a>, <a href="https://publications.waset.org/abstracts/search?q=cement%20factory" title=" cement factory"> cement factory</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20pollution" title=" heavy metal pollution"> heavy metal pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=inorganic%20element" title=" inorganic element"> inorganic element</a>, <a href="https://publications.waset.org/abstracts/search?q=Potamogeton%20natans" title=" Potamogeton natans "> Potamogeton natans </a> </p> <a href="https://publications.waset.org/abstracts/45228/changes-in-inorganic-element-contents-in-potamogeton-natans-exposed-to-cement-factory-pollution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45228.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">274</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> Individual Differences and Language Learning Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilgun%20Karatas">Nilgun Karatas</a>, <a href="https://publications.waset.org/abstracts/search?q=Bihter%20Sakin"> Bihter Sakin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the relationships between the use of language learning strategies and English language exit exam success were investigated in the university EFL learners’ context. The study was conducted at Fatih University Prep School. To collect data 3 classes from the A1 module in English language classes completed a questionnaire known as the English Language Learning Strategy Inventory or ELLSI. The data for the present study were collected from the preparatory class students who are studying English as a second language at the School of Foreign Languages. The students were placed into four different levels of English, namely A1, A2, B1, and B2 level of English competency according to European Union Language Proficiency Standard, by means of their English placement test results. The Placement test was conveyed at the beginning of the spring semester in 2014-2015.The ELLSI consists of 30 strategy items which students are asked to rate from 1 (low frequency) to 5 (high frequency) according to how often they use them. The questionnaire and exit exam results were entered onto SPSS and analyzed for mean frequencies and statistical differences. Spearman and Pearson correlation were used in a detailed way. There were no statistically significant results between the frequency of strategy use and exit exam results.

Lutein accumulates in the macula region of the retina and known as macular pigment which absorbs damaging light in the blue wavelengths. The presence of lutein in retina has been related to decreased risk of two common eye diseases, age-related macular degeneration, and cataract. Being a strong antioxidant, it may also have effects on prevention some types of cancer, cardiovascular disease, cognitive dysfunction. Humans are not capable of synthesizing lutein de novo; therefore it must be provided naturally by the diet, fortified foods, and beverages or nutritional supplement. However, poor bioavailability and physicochemical stability limit its usage in the food industry. Poor solubility in digestive fluids and sensitivity to heat, light, and oxygen are both affect the stability and bioavailability of lutein. In this context, new technologies, delivery systems and formulations have been applied to improve stability and solubility of lutein. Nanotechnology, including nanoemulsion, nanocrystal, nanoencapsulation technology and microencapsulation by complex coacervation, spray drying are promising ways of increasing solubilization of lutein and stability of it in different conditions. Bioavailability of lutein is also dependent on formulations used, starch formulations and milk proteins, especially sodium caseinate are found effective in improving the bioavailability of lutein. Designing foods with highly bioavailable and stabile lutein needs knowledge about current technologies, formulations, and further needs. This review provides an overview of the new technologies and formulations used to improve bioavailability of lutein and also gives a future outlook to food researches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioavailability" title="bioavailability">bioavailability</a>, <a href="https://publications.waset.org/abstracts/search?q=formulation" title=" formulation"> formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=lutein" title=" lutein"> lutein</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title=" nanotechnology"> nanotechnology</a> </p> <a href="https://publications.waset.org/abstracts/81492/improving-lutein-bioavailability-by-nanotechnology-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81492.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">380</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> The Determinants of Female Participation to the Labour Force in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Karacor">Zeynep Karacor</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahime%20Hulya%20Ozturk"> Rahime Hulya Ozturk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Located in developing countries but with the successful performance in recent years have shown in emerging economies , the labor factor has undoubtedly an important place in Turkish economy. The theorists have emphasized the importance of labor and human capital factors for many years. The importance of human capital is emerging in the process of determining the labor force participation rate. It is relatively easy to employ qualified labor force but employment of unskilled labor is particularly difficult. Another factor affecting the gender differences are employment opportunities in the labor force. In our country, the employment conditions of men and women differ. Factors causing these differentials are inherent job requirements, the social structure of society, women's point of view, working hours, working conditions. Crisis in our country in recent years have significantly affect the labor force participation rates. In particular, women's labor force participation rates have shown a decrease in crisis.In crisis female laborforce leave their job and go their home. It is the sole provider of social perception of men so in crisis period it is considered that woman lost their job. In the first part of this study the current situation in the world of female participation in the labor force in Turkey will examine. In the second part of the study literature will be examined. In the third and last part of the study factors of determinants of female labor force participation rate analysis will done by Granger Causality Analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=female%20labour%20force" title="female labour force">female labour force</a>, <a href="https://publications.waset.org/abstracts/search?q=employment" title=" employment"> employment</a>, <a href="https://publications.waset.org/abstracts/search?q=labor%20force" title=" labor force"> labor force</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/59821/the-determinants-of-female-participation-to-the-labour-force-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59821.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">290</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> Reducing the Chemical Activity of Ceramic Casting Molds for Producing Decorated Glass Moulds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilgun%20Kuskonmaz">Nilgun Kuskonmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ceramic molding can produce castings with fine detail, smooth surface and high degree of dimensional accuracy. All these features are the key factors for producing decorated glass moulds. In the ceramic mold casting process, the fundamental parameters affecting the mold-metal reactions are the composition and the properties of the refractory materials used in the production of ceramic mold. As a result of the reactions taking place between the liquid metal and mold surface, it is not possible to achieve a perfect surface quality, a fine surface detail and maintain a high standard dimensional tolerances. The present research examines the effects of the binder composition on the structural and physical properties of the zircon ceramic mold. In the experiment, the ceramic slurry was prepared by mixing the refractory powders (zircon(ZrSiO4), mullit(3Al2O32SiO2) and alumina (Al2O3)) with the low alkaline silica (ethyl silicate (C8H20O4Si)) and acidic type gelling material suitable binder and gelling agent. This was followed by pouring that ceramic slurry on to a silicon pattern. After being gelled, the mold was removed from the silicon pattern and dried. Then, the ceramic mold was subjected to the reaction sintering at 1600°C for 2 hours in the furnace. The stainless steel (SS) was cast into the sintered ceramic mold. At the end of this process it was observed that the surface quality of decorated glass mold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20mold" title="ceramic mold">ceramic mold</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel%20casting" title=" stainless steel casting"> stainless steel casting</a>, <a href="https://publications.waset.org/abstracts/search?q=decorated%20glass%20mold" title=" decorated glass mold"> decorated glass mold</a> </p> <a href="https://publications.waset.org/abstracts/68215/reducing-the-chemical-activity-of-ceramic-casting-molds-for-producing-decorated-glass-moulds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68215.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">263</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The Effect of Saccharomyces cerevisiae Live Yeast Culture on Microbial Nitrogen Supply to Small Intestine in Male Kivircik Yearlings Fed with Different Ratio of Forage and Concentrate </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurcan%20Cetinkaya">Nurcan Cetinkaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadide%20Hulya%20Ozdemir"> Nadide Hulya Ozdemir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study was to investigate the effect of Saccharomyces cerevisiae (SC) live yeast culture on microbial protein supply to the small intestine in Kivircik male yearlings when fed with different ratio of forage and concentrate diets. Four Kivircik male yearlings with permanent rumen canula were used in the experiment. . The treatments were allocated to a 4x4 Latin square design. Diet I consisted of 70% alfalfa hay and 30% concentrate, Diet II consisted of 30% alfalfa hay and 70% concentrate, Diet I and II were supplemented with a SC. Daily urine was collected and stored at -20°C until analysis. Calorimetric methods were used for the determination of urinary allantoin and creatinin levels. The estimated microbial N supply to small intestine for Diets I, I+SC, II and II+SC were 2.51, 2.64, 2.95 and 3.43 g N/d respectively. Supplementation of Diets I and II with SC significantly affected the allantoin levels in µmol/W0. 75 (p<0.05). Mean creatinine values in µmol/W0. 75 and allantoin:creatinin ratios were not significantly different among diets. In conclusion, supplementation with SC live yeast culture had a significant effect on urinary allantoin excretion and microbial protein supply to small intestine in Kivircik yearlings fed with high concentrate Diet II (P<0.05). Hence urinary allantoin excretion may be used as a tool for estimating microbial protein supply in Kivircık yearlings.

Stigma represents a serious obstacle to recovery and social integration for people who experience a mental illness, affecting directly their well-being and quality of life. It implies that these persons have to deal with many other barriers apart from the disease symptoms (1-5). Convergent, recent literature suggests that less positive attitudes by mental health professionals interfere with the self-determination and recovery process (4-10).The aim of this study was to translate the Attribution Questionnaire-27 (AQ-27) to the Turkish language (AQ-27-T), and to examine the reliability and validity of this new Turkish version. Cultural adaptation was implemented according to the internationally suggested method. To determine the understandability and appropriateness of this measure for the Turkish culture, a pretest was administered and the final form was generated. Then, 424 randomly chosen people took part in the study. Participant’s mean age was 36.9±12.7 years and %52 of them female. Cronbach's alpha and intra-class coefficients were used to estimate instrument reliability. The AQ-27-T was assessed again 14 days later for test retest reliability. The AQ-27-T demonstrated acceptable internal consistency, with a Cronbach's alpha of 0.88 for the total scale and ranging between 0.86 and 0.89 for the items. The test-retest reliability was good, with Pearson correlation coefficients of 0.79 for the total scale and ranging between 0.35 and 0.77 for the items (p<0.05). Correlation between subscales was moderate-good, with Pearson correlation coefficients of 0.18-0.88 (p<0.05). Fit indices of the model supported the factor structure and paths. The AQ-27-T is a reliable measure to assess stigmatizing attitudes in Turkish. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attribution%20questionnaire" title="attribution questionnaire">attribution questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=validity" title=" validity"> validity</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=stigma" title=" stigma"> stigma</a> </p> <a href="https://publications.waset.org/abstracts/40371/stigma-and-discrimination-toward-mental-illness-translation-and-validation-of-the-attribution-questionnaire-27-aq-27" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40371.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">442</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> Significance of Occupational Safety for Healthcare Professionals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilg%C3%BCn%20Katranc%C4%B1">Nilgün Katrancı</a>, <a href="https://publications.waset.org/abstracts/search?q=P%C4%B1nar%20G%C3%B6v"> Pınar Göv</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The privatization of public services has intensified and extended the delivery of healthcare services at hospitals, which leads to an increase in health and safety risks for healthcare professionals. More efficient and effective delivery of healthcare services can be realized through the provision of occupational safety of healthcare professionals. However, healthcare professionals are exposed to more dangers, accidents, and diseases because of such reasons as present working conditions, hospital infections, lack of ergonomic design, medication, wastes, excessive work load, negligent attitudes of workers, violence, psychological risks, etc. Unsafe working conditions cause fear, injury and wearing impacts in healthcare professionals in many countries. Thus, it is emphasized that the protection of the health of healthcare professionals is important to have educated, healthy workers and adequate workforce. Occupational health and safety measures applied in health facilities are aimed at protecting workers and providing the safety of services and facilities. All activities to be undertaken at hospitals with regard to occupational safety in accordance with these goals will help to reduce costs and provide continuous services. At the same time, a safe working environment will increase worker satisfaction and motivation, sense of institutional belonging and indirectly patient safety and satisfaction. In addition, the control and correction of occupational safety activities are also as important as the implementation. Occupational health and safety practices in the facilities will also lead to positive developments for national economy and society. This study emphasizes that approaching occupational safety practices for healthcare professionals in a sensitive manner is important for enabling healthcare professionals to do more productive works in terms of physical, social and psychological aspects, maintaining the continuity of healthcare services and social and economic contributions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20facilities" title="health facilities">health facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20professional" title=" healthcare professional"> healthcare professional</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health" title=" occupational health"> occupational health</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20safety" title=" occupational safety"> occupational safety</a> </p> <a href="https://publications.waset.org/abstracts/76499/significance-of-occupational-safety-for-healthcare-professionals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76499.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">385</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> Synthesis and Properties of Oxidized Corn Starch Based Wood Adhesive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salise%20Oktay">Salise Oktay</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilgun%20Kizilcan"> Nilgun Kizilcan</a>, <a href="https://publications.waset.org/abstracts/search?q=Basak%20Bengu"> Basak Bengu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At present, formaldehyde-based adhesives such as urea-formaldehyde (UF), melamine-formaldehyde (MF), melamine – urea-formaldehyde (MUF), etc. are mostly used in wood-based panel industry because of their high reactivity, chemical versatility, and economic competitiveness.

Therefore, there has been a growing interest in the development of environment-friendly, economically competitive, bio-based wood adhesives to meet wood-based panel industry requirements. In this study, like a formaldehyde-free adhesive, oxidized starch – urea wood adhesives was synthesized. In this scope, firstly, acid hydrolysis of corn starch was conducted and then acid thinned corn starch was oxidized by using hydrogen peroxide and CuSO₄ as an oxidizer and catalyst, respectively. Secondly, the polycondensation reaction between oxidized starch and urea conducted. Finally, nano – TiO₂ was added to the reaction system to strengthen the adhesive network.

FTIR, DSC, TGA, SEM characterization techniques were used to investigate chemical structures, thermal, and morphological properties of the adhesive, respectively. Rheological analysis of the adhesive was also performed. In order to evaluate the quality of oxidized corn starch – urea adhesives, particleboards were produced in laboratory scale and mechanical and physical properties of the boards were investigated such as an internal bond, modulus of rupture, modulus of elasticity, formaldehyde emission, etc. The obtained results revealed that oxidized starch – urea adhesives were synthesized successfully and it can be a good potential candidate to use the wood-based panel industry with some developments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano-TiO%E2%82%82" title="nano-TiO₂">nano-TiO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20starch" title=" corn starch"> corn starch</a>, <a href="https://publications.waset.org/abstracts/search?q=formaldehyde%20emission" title=" formaldehyde emission"> formaldehyde emission</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20adhesives" title=" wood adhesives"> wood adhesives</a> </p> <a href="https://publications.waset.org/abstracts/115506/synthesis-and-properties-of-oxidized-corn-starch-based-wood-adhesive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115506.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">151</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> The Microstructural and Mechanical Characterization of Organo-Clay-Modified Bitumen, Calcareous Aggregate, and Organo-Clay Blends</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20G%C3%BCrses">A.

Bitumen is a liquid at high temperature and it becomes brittle at low temperatures, and this temperature-sensitivity can cause the rutting and cracking of the pavement and limit its application. Therefore, the properties of existing asphalt materials need to be enhanced. The pavement with polymer modified bitumen exhibits greater resistance to rutting and thermal cracking, decreased fatigue damage, as well as stripping and temperature susceptibility; however, they are expensive and their applications have disadvantages. Bituminous mixtures are composed of very irregular aggregates bound together with hydrocarbon-based asphalt, with a low volume fraction of voids dispersed within the matrix. Montmorillonite (MMT) is a layered silicate with low cost and abundance, which consists of layers of tetrahedral silicate and octahedral hydroxide sheets. Recently, the layered silicates have been widely used for the modification of polymers, as well as in many different fields. However, there are not too much studies related with the preparation of the modified asphalt with MMT, currently. In this study, organo-clay-modified bitumen, and calcareous aggregate and organo-clay blends were prepared by hot blending method with OMMT, which has been synthesized using a cationic surfactant (Cetyltrymethylammonium bromide, CTAB) and long chain hydrocarbon, and MMT. When the exchangeable cations in the interlayer region of pristine MMT were exchanged with hydrocarbon attached surfactant ions, the MMT becomes organophilic and more compatible with bitumen. The effects of the super hydrophobic OMMT onto the micro structural and mechanic properties (Marshall Stability and volumetric parameters) of the prepared blends were investigated. Stability and volumetric parameters of the blends prepared were measured using Marshall Test. Also, in order to investigate the morphological and micro structural properties of the organo-clay-modified bitumen and calcareous aggregate and organo-clay blends, their SEM and HRTEM images were taken. It was observed that the stability and volumetric parameters of the prepared mixtures improved significantly compared to the conventional hot mixes and even the stone matrix mixture. A micro structural analysis based on SEM images indicates that the organo-clay platelets dispersed in the bitumen have a dominant role in the increase of effectiveness of bitumen - aggregate interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20mix%20asphalt" title="hot mix asphalt">hot mix asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=stone%20matrix%20asphalt" title=" stone matrix asphalt"> stone matrix asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=organo%20clay" title=" organo clay"> organo clay</a>, <a href="https://publications.waset.org/abstracts/search?q=Marshall%20test" title=" Marshall test"> Marshall test</a>, <a href="https://publications.waset.org/abstracts/search?q=calcareous%20aggregate" title=" calcareous aggregate"> calcareous aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20bitumen" title=" modified bitumen"> modified bitumen</a> </p> <a href="https://publications.waset.org/abstracts/53072/the-microstructural-and-mechanical-characterization-of-organo-clay-modified-bitumen-calcareous-aggregate-and-organo-clay-blends" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53072.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">238</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> Assessment of Intern Students' Attitudes towards Medical Errors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nilg%C3%BCn%20Katranc%C4%B1">Nilgün Katrancı</a>, <a href="https://publications.waset.org/abstracts/search?q=P%C4%B1nar%20G%C3%B6v"> Pınar Göv</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the acceleration and assessment of quality and patient safety works in healthcare services in the 21st century, activities to reduce errors have gained importance. The prevention and reduction of unintended consequences related to healthcare services and errors made during the delivery of healthcare services can be achieved by understanding the causes of the errors. Communication is the basic reason most frequently seen in such cases. Nurses who communicate with patients more closely and for longer time play a more critical role in ensuring patient safety compared to other healthcare professionals. To reduce the risk of medical errors and increase the quality of care, it is important to raise the awareness of nurses about patient safety in training period. This descriptive study was conducted between February 2017 and May 2017 to assess intern students' attitudes towards and knowledge of patient safety and medical errors. The target population of the study consists of intern students at the Faculty of Nursing in Gaziantep University (N=180). The study did not apply any sample selection method, and the research group consisted of 90 female and 37 male senior students who were available and accepted to take part in the study (N=127). The study used personal information form and medical error attitude scale to collect data. The medical error attitude scale consists of 16 items and 3 sub-dimensions. The most frequently seen medical error in the clinics the interns worked at was found as ‘Failure to comply with asepsis rules’ with a rate of 67,7%. The most frequent case among reasons for not disclosing an error is ‘noticing and correcting the error before affecting the patient’ with the rate of 70,9%. The most frequently expressed implications of disclosing a serious error for the intern students participating in the study are ‘harming patient trust (78%)’ and ‘possibility of overreaction by patient (62,2%)’. According to the results of the study, the awareness of the students about the importance of medical errors and error reporting was found high (3,48 ± 0,49). Consequently, it is important to assess and positively improve the attitudes of nurses and other healthcare professionals towards medical errors for the determination of causes of medical errors and their prevention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare%20service" title="healthcare service">healthcare service</a>, <a href="https://publications.waset.org/abstracts/search?q=intern%20student" title=" intern student"> intern student</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20error" title=" medical error"> medical error</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20safety" title=" patient safety"> patient safety</a> </p> <a href="https://publications.waset.org/abstracts/76497/assessment-of-intern-students-attitudes-towards-medical-errors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76497.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">203</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> Effects of the Coagulation Bath and Reduction Process on SO2 Adsorption Capacity of Graphene Oxide Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96zge%20Alpto%C4%9Fa">Özge Alptoğa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuray%20U%C3%A7ar"> Nuray Uçar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilg%C3%BCn%20Karatepe%20Yavuz"> Nilgün Karatepe Yavuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ay%C5%9Fen%20%C3%96nen"> Ayşen Önen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sulfur dioxide (SO<sub>2</sub>) is a very toxic air pollutant gas and it causes the greenhouse effect, photochemical smog, and acid rain, which threaten human health severely. Thus, the capture of SO<sub>2</sub> gas is very important for the environment. Graphene which is two-dimensional material has excellent mechanical, chemical, thermal properties, and many application areas such as energy storage devices, gas adsorption, sensing devices, and optical electronics. Further, graphene oxide (GO) is examined as a good adsorbent because of its important features such as functional groups (epoxy, carboxyl and hydroxyl) on the surface and layered structure. The SO<sub>2</sub> adsorption properties of the fibers are usually investigated on carbon fibers. In this study, potential adsorption capacity of GO fibers was researched. GO dispersion was first obtained with Hummers’ method from graphite, and then GO fibers were obtained via wet spinning process. These fibers were converted into a disc shape, dried, and then subjected to SO<sub>2</sub> gas adsorption test. The SO<sub>2</sub> gas adsorption capacity of GO fiber discs was investigated in the fields of utilization of different coagulation baths and reduction by hydrazine hydrate. As coagulation baths, single and triple baths were used. In single bath, only ethanol and CaCl<sub>2</sub> (calcium chloride) salt were added. In triple bath, each bath has a different concentration of water/ethanol and CaCl<sub>2</sub> salt, and the disc obtained from triple bath has been called as reference disk. The fibers which were produced with single bath were flexible and rough, and the analyses show that they had higher SO<sub>2</sub> adsorption capacity than triple bath fibers (reference disk). However, the reduction process did not increase the adsorption capacity, because the SEM images showed that the layers and uniform structure in the fiber form were damaged, and reduction decreased the functional groups which SO<sub>2</sub> will be attached. Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD) analyzes were performed on the fibers and discs, and the effects on the results were interpreted. In the future applications of the study, it is aimed that subjects such as pH and additives will be examined. <p class="card-text"><strong>Keywords:</strong> <a
