However, it is not the same procedure for all different target groups; meanwhile, during data collection from teenagers, young adults, or adults, researchers can use common data collection tools such as questionnaires, interviews, and semi-structured interviews; yet, for young learners and very young ones, these reliable and valid data collection tools cannot be easily designed or applied by the researchers. In this study, firstly, common data collection tools are examined for ‘very young’ and ‘young learners’ participant groups since it is thought that the quality and efficiency of an academic study is mainly based on its valid and correct data collection and data analysis procedure. Secondly, two different data collection instruments for very young and young learners are stated as discussing the efficacy of them. Finally, a suggested data collection tool – a performance-based questionnaire- which is specifically developed for ‘very young’ and ‘young learners’ participant groups in the field of teaching English to young learners as a foreign language is presented in this current study. The designing procedure and suggested items/factors for the suggested data collection tool are accordingly revealed at the end of the study to help researchers have studied with young and very learners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20collection%20instruments" title="data collection instruments">data collection instruments</a>, <a href="https://publications.waset.org/abstracts/search?q=performance-based%20questionnaire" title=" performance-based questionnaire"> performance-based questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20learners" title=" young learners"> young learners</a>, <a href="https://publications.waset.org/abstracts/search?q=very%20young%20learners" title=" very young learners"> very young learners</a> </p> <a href="https://publications.waset.org/abstracts/169544/the-perspective-on-data-collection-instruments-for-younger-learners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169544.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2505</span> Influences of Victimization Experiences on Delinquency: Comparison between Young Offenders and Non-Offenders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yoshihiro%20Horio">Yoshihiro Horio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many young offenders grow up in difficult environments. It has often been suggested that many young offenders are victims of abuse. However, there were restricted to abuse or family’s problem. Little research has examined data on ‘multiple victimization’ experiences of young offenders. Thus, this study investigated the victimization experiences of young offenders, including child abuse at home, bullying at school, and crime in the community. Specifically, the number of victimization experiences of young offenders was compared with those of non-delinquents at home, school, and in the community. It was found that young offenders experienced significantly more victimization than non-delinquents. Additionally, the influence of childhood victimization on later misconduct and/or delinquency was examined, then it was founded that victimization experiences to be a risk factor for subsequent delinquency. The hierarchical multiple regression analysis showed that young offenders who had a strong emotional reaction to their experience of abuse began their misconduct at an earlier age. If juveniles start their misconduct early, the degree of delinquency will increase. The anger of young offenders was stronger than that of non-delinquents. A strong emotion of anger may be related to juvenile delinquency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abuse" title="abuse">abuse</a>, <a href="https://publications.waset.org/abstracts/search?q=bullying" title=" bullying"> bullying</a>, <a href="https://publications.waset.org/abstracts/search?q=delinquency" title=" delinquency"> delinquency</a>, <a href="https://publications.waset.org/abstracts/search?q=victimization" title=" victimization"> victimization</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20offenders" title=" young offenders"> young offenders</a> </p> <a href="https://publications.waset.org/abstracts/97970/influences-of-victimization-experiences-on-delinquency-comparison-between-young-offenders-and-non-offenders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97970.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">243</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">2504</span> Predicting Seoul Bus Ridership Using Artificial Neural Network Algorithm with Smartcard Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hosuk%20Shin">Hosuk Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Hyun%20Seo"> Young-Hyun Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Eunhak%20Lee"> Eunhak Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Young%20Kho"> Seung-Young Kho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, in Seoul, users have the privilege to avoid riding crowded buses with the installation of Bus Information System (BIS). BIS has three levels of on-board bus ridership level information (spacious, normal, and crowded). However, there are flaws in the system due to it being real time which could provide incomplete information to the user. For example, a bus comes to the station, and on the BIS it shows that the bus is crowded, but on the stop that the user is waiting many people get off, which would mean that this station the information should show as normal or spacious. To fix this problem, this study predicts the bus ridership level using smart card data to provide more accurate information about the passenger ridership level on the bus. An Artificial Neural Network (ANN) is an interconnected group of nodes, that was created based on the human brain. Forecasting has been one of the major applications of ANN due to the data-driven self-adaptive methods of the algorithm itself. According to the results, the ANN algorithm was stable and robust with somewhat small error ratio, so the results were rational and reasonable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smartcard%20data" title="smartcard data">smartcard data</a>, <a href="https://publications.waset.org/abstracts/search?q=ANN" title=" ANN"> ANN</a>, <a href="https://publications.waset.org/abstracts/search?q=bus" title=" bus"> bus</a>, <a href="https://publications.waset.org/abstracts/search?q=ridership" title=" ridership"> ridership</a> </p> <a href="https://publications.waset.org/abstracts/85135/predicting-seoul-bus-ridership-using-artificial-neural-network-algorithm-with-smartcard-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85135.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">2503</span> Relationship between Driving under the Influence and Traffic Safety</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eun%20Hak%20Lee">Eun Hak Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Hyun%20Seo"> Young-Hyun Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hosuk%20Shin"> Hosuk Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Young%20Kho"> Seung-Young Kho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among traffic crashes, driving under the influence (DUI) of alcohol is the most dangerous behavior in Seoul, South Korea. In 2016 alone 40 deaths occurred on of 2,857 cases of DUI. Since DUI is one of the major factors in increasing the severity of crashes, the intensive management of DUI required to reduce traffic crash deaths and the crash damages. This study aims to investigate the relationship between DUI and traffic safety in order to establish countermeasures for traffic safety improvement. The analysis was conducted on the habitual drivers who drove under the influence. Information of habitual drivers is matched to crash data and fine data. The descriptive statistics on data used in this study, which consists of driver license acquisition, traffic fine, and crash data provided by the Korean National Police Agency, are described. The drivers under the influence are classified by statistically significant criteria, such as driver’s age, license type, driving experience, and crash reasons. With the results of the analysis, we propose some countermeasures to enhance traffic safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=driving%20under%20influence" title="driving under influence">driving under influence</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20safety" title=" traffic safety"> traffic safety</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20crash" title=" traffic crash"> traffic crash</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20fine" title=" traffic fine"> traffic fine</a> </p> <a href="https://publications.waset.org/abstracts/85925/relationship-between-driving-under-the-influence-and-traffic-safety" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85925.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">222</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">2502</span> Young Carers’ Dilemma: Family Responsibility, Bonding and Commitment to Supporting Their Mentally Ill Parent in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esabella%20Yuan">Esabella Yuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study explored the recollections of young carers who lived with and cared for their mentally ill parent and how they managed life difficulties in Taiwan. 19 former young carers took part in the study, conducted from July to October 2021. The findings provided the unique view that all the participants acknowledged being taught by the mainstream culture to honour family value and prioritize the needs of parents over their own ones, they stepped in to care for the ill parent out of love and out of necessity through there having no-one to turn to, they were willing to assume long-term caring responsibilities, strikingly, a much more common experience was that the participants hided parental illness and young carer identity in the community through the fear of social discrimination attached to mental illness. As a result, these former young carers stayed in hidden circumstances and coped alone with caring challenges. The findings suggest that there needs multi-disciplinary services working together to recognize the needs of young carers and provide appropriate intervention to young carers based on a family-focus approach and ensure to serve the best interests of young carers and their families. It is to be hope that young carers can grow up safely and healthily within the community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=young%20carers" title="young carers">young carers</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20well-being" title=" family well-being"> family well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=parental%20mental%20illness" title=" parental mental illness"> parental mental illness</a> </p> <a href="https://publications.waset.org/abstracts/158979/young-carers-dilemma-family-responsibility-bonding-and-commitment-to-supporting-their-mentally-ill-parent-in-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158979.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">89</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">2501</span> Advanced CoMP Scheme for LTE-based V2X System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Su-Hyun%20Jung">Su-Hyun Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Su%20Ryu"> Young-Su Ryu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Jun%20Kim"> Yong-Jun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung-Kyu%20Song"> Hyoung-Kyu Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a highly efficient coordinated multiple-point (CoMP) scheme for vehicular communication is proposed.

Farrell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The prediction of the vibration response of rubber products by analytical or numerical method depends mainly on the predefined intrinsic material properties such as Young’s modulus, damping factor and Poisson’s ratio. Such intrinsic properties are determined experimentally by subjecting a bonded rubber sample to compression tests. The compression tests on such a sample yield an apparent Young’s modulus which is greater in magnitude than the intrinsic Young’s modulus of the rubber. As a result, many analytical equations have been developed to determine Young’s modulus from an apparent Young’s modulus of bonded rubber materials. In this work, the applicability of some of these analytical equations is assessed via experimental testing. The assessment is based on testing of vulcanized nitrile butadiene rubber (NBR70) samples using tensile test and compression test methods. The analytical equations are used to determine the intrinsic Young’s modulus from the apparent modulus that is derived from the compression test data of the bonded rubber samples. Then, these Young’s moduli are compared with the actual Young’s modulus that is derived from the tensile test data. The results show significant discrepancy between the Young’s modulus derived using the analytical equations and the actual Young’s modulus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bonded%20rubber" title="bonded rubber">bonded rubber</a>, <a href="https://publications.waset.org/abstracts/search?q=quasi-static%20test" title=" quasi-static test"> quasi-static test</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20factor" title=" shape factor"> shape factor</a>, <a href="https://publications.waset.org/abstracts/search?q=apparent%20Young%E2%80%99s%20modulus" title=" apparent Young’s modulus"> apparent Young’s modulus</a> </p> <a href="https://publications.waset.org/abstracts/104859/assessment-of-analytical-equations-for-the-derivation-of-youngs-modulus-of-bonded-rubber-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104859.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2498</span> A Different Approach to Optimize Fuzzy Membership Functions with Extended FIR Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jun-Ho%20Chung">Jun-Ho Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Hyun%20Yoo"> Sung-Hyun Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Hwan%20Choi"> In-Hwan Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Kook%20Lee"> Hyun-Kook Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Moon-Kyu%20Song"> Moon-Kyu Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Choon-Ki%20Ahn"> Choon-Ki Ahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The extended finite impulse response (EFIR) filter is addressed to optimize membership functions (MFs) of the fuzzy model that has strong nonlinearity.

In this study, 2010 Household Travel Survey data were used and improper samples were removed through the analysis. Chosen alternative, date of birth, mode, origin code, destination code, departure time, and arrival time are considered from Household Travel Survey. By preprocessing data, travel time, travel cost, mode, and ratio of people aged 45 to 55 years, 55 to 65 years and over 65 years were calculated. After the manipulation, the mode choice model was constructed using LIMDEP by maximum likelihood estimation. A significance test was conducted for nine parameters, three age groups for three modes. Then the test was conducted again for the mode choice model with significant parameters, travel cost variable and travel time variable. As a result of the model estimation, as the age increases, the preference for the car decreases and the preference for the bus increases. This study is meaningful in that the individual and households characteristics are applied to the aggregate model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age%20grouping" title="age grouping">age grouping</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20choice%20model" title=" mode choice model"> mode choice model</a>, <a href="https://publications.waset.org/abstracts/search?q=multinomial%20logit%20model" title=" multinomial logit model"> multinomial logit model</a> </p> <a href="https://publications.waset.org/abstracts/69640/a-study-of-mode-choice-model-improvement-considering-age-grouping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69640.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">322</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">2495</span> Improved Structure and Performance by Shape Change of Foam Monitor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tae%20Gwan%20Kim">Tae Gwan Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Kyu%20Cho"> Hyun Kyu Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Hoon%20Lee"> Young Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Chul%20Park"> Young Chul Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Foam monitors are devices that are installed on cargo tank decks to suppress cargo area fires in oil tankers or hazardous chemical ship cargo ships. In general, the main design parameter of the foam monitor is the distance of the projection through the foam monitor. In this study, the relationship between flow characteristics and projection distance, depending on the shape was examined. Numerical techniques for fluid analysis of foam monitors have been developed for prediction. The flow pattern of the fluid varies depending on the shape of the flow path of the foam monitor, as the flow losses affecting projection distance were calculated through numerical analysis. The basic shape of the foam monitor was an L shape designed by N Company. The modified model increased the length of the flow path and used the S shape model. The calculation result shows that the L shape, which is the basic shape, has a problem that the force is directed to one side and the vibration and noise are generated there. In order to solve the problem, S-shaped model, which is a change model, was used. As a result, the problem is solved, and the projection distance from the nozzle is improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=foam%20monitor" title=" foam monitor"> foam monitor</a>, <a href="https://publications.waset.org/abstracts/search?q=projection%20distance" title=" projection distance"> projection distance</a>, <a href="https://publications.waset.org/abstracts/search?q=moment" title=" moment"> moment</a> </p> <a href="https://publications.waset.org/abstracts/66229/improved-structure-and-performance-by-shape-change-of-foam-monitor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66229.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">343</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">2494</span> The Savior, the Absent, and the Model: The Role Social Workers Play in Young Women’s Romantic Relationships</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tehila%20Wright">Tehila Wright</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Being involved in romantic relationships is a key task in the development of identity during emerging adulthood. To date, little research has focused on romantic relationships among young women who have coped with situations of distress and are treated by social workers. Moreover, the role of social workers in young women’s romantic relations is underexplored. This paper focuses on young women’s perception of the role played by their social workers in guiding them through romantic relationships. Methodology: This qualitative-feminist study is based on semi-structured in-depth interviews with 25 young heterosexual Jewish women aged 18-25 who are currently supported by social workers in the welfare system. Findings: The findings uncover three meanings given by participants to their relations with social workers regarding the young women's romantic relationships: 1)” The social worker as role model” namely, the social worker as setting an example for healthy conduct in romantic relationships. 2) "The social worker as savior," namely, the social worker as the one who supports participants escaping abusive romantic relationships. 3) "The present-absent social worker,” namely, despite being a significant figure in their lives, the social worker is experienced as disconnected and alienated. Conclusions and practice: Social workers can have a positive and important contribution to the romantic relationships of these young women. To be a central source of support in the young women's life, the social workers must be able to establish a relationship of trust with the young women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=young%20women" title="young women">young women</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20adulthood" title=" emerging adulthood"> emerging adulthood</a>, <a href="https://publications.waset.org/abstracts/search?q=romantic%20relationship" title=" romantic relationship"> romantic relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=women%20in%20distress" title=" women in distress"> women in distress</a> </p> <a href="https://publications.waset.org/abstracts/154892/the-savior-the-absent-and-the-model-the-role-social-workers-play-in-young-womens-romantic-relationships" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154892.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">109</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">2493</span> Evaluation of Developmental Toxicity and Teratogenicity of Perfluoroalkyl Compounds Using FETAX</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun-Kyung%20Lee">Hyun-Kyung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jehyung%20Oh"> Jehyung Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Eun%20Jeong"> Young Eun Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Shik%20Lee"> Hyun-Shik Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Perfluoroalkyl compounds (PFCs) are environmental toxicants that persistently accumulate in the human blood. Their widespread detection and accumulation in the environment raise concerns about whether these chemicals might be developmental toxicants and teratogens in the ecosystem. We evaluated and compared the toxicity of PFCs of containing various numbers of carbon atoms (C8-11 carbons) on vertebrate embryogenesis. We assessed the developmental toxicity and teratogenicity of various PFCs. The toxic effects on Xenopus embryos were evaluated using different methods. We measured teratogenic indices (TIs) and investigated the mechanisms underlying developmental toxicity and teratogenicity by measuring the expression of organ-specific biomarkers such as xPTB (liver), Nkx2.5 (heart), and Cyl18 (intestine). All PFCs that we tested were found to be developmental toxicants and teratogens. Their toxic effects were strengthened with increasing length of the fluorinated carbon chain. Furthermore, we produced evidence showing that perfluorodecanoic acid (PFDA) and perfluoroundecanoic acid (PFuDA) are more potent developmental toxicants and teratogens in an animal model compared to the other PFCs we evaluated [perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA)]. In particular, severe defects resulting from PFDA and PFuDA exposure were observed in the liver and heart, respectively, using the whole mount in situ hybridization, real-time PCR, pathologic analysis of the heart, and dissection of the liver. Our studies suggest that most PFCs are developmental toxicants and teratogens, however, compounds that have higher numbers of carbons (i.e., PFDA and PFuDA) exert more potent effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PFC" title="PFC">PFC</a>, <a href="https://publications.waset.org/abstracts/search?q=xenopus" title=" xenopus"> xenopus</a>, <a href="https://publications.waset.org/abstracts/search?q=fetax" title=" fetax"> fetax</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a> </p> <a href="https://publications.waset.org/abstracts/46966/evaluation-of-developmental-toxicity-and-teratogenicity-of-perfluoroalkyl-compounds-using-fetax" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46966.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">2492</span> SCR-Based Advanced ESD Protection Device for Low Voltage Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bo%20Bae%20Song">Bo Bae Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung%20Seok%20Lee"> Byung Seok Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20young%20Kim"> Hyun young Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung%20Kwang%20Lee"> Chung Kwang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Seo%20Koo"> Yong Seo Koo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposed a silicon controller rectifier (SCR) based ESD protection device to protect low voltage ESD for integrated circuit.

Aster yomena (Kitam.) Honda (A. yomena) belonging to Compositae family is a perennial plant, and it has anti-inflammatory, anti-asthmatic and anti-obesity effects. In this study, we investigated the antioxidative effect of A. yomena by measuring 2, 2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl radical (˙OH) and superoxide radical (O₂⁻) scavenging activities in vitro. A. yomena was extracted with ethanol and then partitioned with n-hexane, methylene chloride (CH₂Cl₂), ethyl acetate (EtOAc) and n-butanol (n-BuOH). In DPPH radical scavenging assay, the concentration of A. yomena from 10 to 100μg/mL dose-dependently raised the inhibition of DPPH oxidation. Especially, EtOAc fraction of A. yomena showed the highest DPPH radical scavenging activity among other fractions. The ˙OH radical scavenging activities of the extract and four fractions of A. yomena were increased by over 80% at a concentration of 50μg/mL. Especially, the IC50 value of EtOAc fraction was 0.03 μg/mL that is the lowest value compared with the values of other fractions. In addition, we found that the EtOAc fraction of A. yomena was showed to be better at O₂⁻ radical scavenging than other fractions. Taken together these results, we suggested that A. yomena, especially EtOAc fraction, can be used as a natural antioxidant against free radicals.

POTS predominantly occurs in young women. Regular exercise has proven to improve the organ system functions, including autonomous systems. The aim of this research was to determine the correlation between exercise frequency and POTS in young women. Method: 510 young women (16-23 years of age) were screened. They were obtained by interview and physical examination. The diagnosis of POTS was performed with Active Stand Test (AST) and heart rate measurement using a pulsemeter. There were 29 young women who suffered from POTS. The exercise frequency was obtained by interview. Data was statistically analyzed using Spearman Correlation test. Result: The subjects’, who tested positive for POTS didn’t perform regular exercise. The Spearman correlation test showed there was a moderate negative correlation between exercise frequency and POTS in young women (r = -0.487, p < 0.00). Conclusion: There is a moderate reverse correlation between exercise frequency and POTS in young women. Further studies are suggested to develop an exercise program for young who suffered from POTS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=POTS" title="POTS">POTS</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomic%20dysfunction" title=" autonomic dysfunction"> autonomic dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise%20frequency" title=" exercise frequency"> exercise frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20woman" title=" young woman"> young woman</a> </p> <a href="https://publications.waset.org/abstracts/31900/the-correlation-between-of-medicine-and-postural-orthostatic-tachycardia-syndrome-pots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31900.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">556</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">2488</span> A Statistical Study on Young UAE Driver’s Behavior towards Road Safety</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadia%20Afroza">Sadia Afroza</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakiba%20Rouf"> Rakiba Rouf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Road safety and associated behaviors have received significant attention in recent years, reflecting general public concern. This paper portrays a statistical scenario of the young drivers in UAE with emphasis on various concern points of young driver’s behavior and license issuance. Although there are many factors contributing to road accidents, statistically it is evident that age plays a major role in road accidents. Despite ensuring strict road safety laws enforced by the UAE government, there is a staggering correlation among road accidents and young driver’s at UAE. However, private organizations like BMW and RoadSafetyUAE have extended its support on conducting surveys on driver’s behavior with an aim to ensure road safety. Various strategies such as road safety law enforcement, license issuance, adapting new technologies like safety cameras and raising awareness can be implemented to improve the road safety concerns among young drivers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=driving%20behavior" title="driving behavior">driving behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=Graduated%20Driver%20Licensing%20System%20%28GLDS%29" title=" Graduated Driver Licensing System (GLDS)"> Graduated Driver Licensing System (GLDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE%20drivers" title=" UAE drivers"> UAE drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20drivers" title=" young drivers"> young drivers</a> </p> <a href="https://publications.waset.org/abstracts/80430/a-statistical-study-on-young-uae-drivers-behavior-towards-road-safety" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80430.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">261</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">2487</span> An Overview of the Risk for HIV/AIDS among Young Women in South Africa: Gender Based Violence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaneil%20Taylor">Shaneil Taylor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gender-based violence is a reflection of the inequalities that are associated within a society between the men and women that affects the health, dignity, security and autonomy of its victims. There are various determinants that contribute to the health risk of young women who have experienced sexual violence, in countries that have a high prevalence rate for HIV. For instance, in South Africa, where the highest prevalence rate for HIV is among young women, their susceptibility to the virus has been increased by sexual violence and cultural inequalities. Therefore, this study is a review of literature that explores how gender-based violence increases the possibility for HIV/AIDS among young women in South Africa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender-based%20violence" title="gender-based violence">gender-based violence</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV%2FAIDS%20transmission" title=" HIV/AIDS transmission"> HIV/AIDS transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=risky%20sexual%20behavior" title=" risky sexual behavior"> risky sexual behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20women" title=" young women"> young women</a> </p> <a href="https://publications.waset.org/abstracts/33568/an-overview-of-the-risk-for-hivaids-among-young-women-in-south-africa-gender-based-violence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33568.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">531</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">2486</span> Stereotypes and Glass Ceiling Barriers for Young Women’s Leadership </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amna%20Khaliq">Amna Khaliq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, the phenomena of common stereotypes and glass ceiling barriers in women’s career advancement in men dominating society are explored.

Since the 70% ethanol extract of Acanthopanax koreanum inhibited MMP-13 expression in IL-1β-treated human chondrocyte cell line, SW1353, two major constituents including acanthoic acid and impressic acid were initially isolated from the same plant materials and their MMP-13 down-regulating capacity was examined. In IL-1β-treated SW1353 cells, acanthoic acid and impressic acid significantly and concentration-dependently inhibited MMP-13 expression at 10 – 100 μM and 0.5 – 10 μM, respectively. The potent one, impressic acid, was found to inhibit MMP-13 expression by blocking the phosphorylation of signal transducer and activator of transcription-1/-2 (STAT-1/-2) and activation of c-Jun and c-Fos among cellular signaling pathway involved, but did not affect the activation of mitogen-activated protein kinases (MAPKs) and nuclear transcription factor-κB (NF-κB). Further, impressic acid was also found to inhibit the expression of MMP-13 mRNA (47.7% inhibition at 10 μM), the glycosaminoglycan release (42.2% reduction at 10 μM) and proteoglycan loss in IL-1-treated rabbit cartilage explants culture. For a further study, 21 impressic acid derivatives were isolated from the same plant materials and their suppressive activities against MMP-13 expression were examined. Among the derivatives, 3α-hydroxy-lup-20(29)-en-23-oxo,28-oic acid, (20R)-3α-hydroxy-29-dimethoxylupan-23,28-dioic acid, acankoreoside F and acantrifoside A clearly down-regulated MMP-13 expression, but impressic acid being most potent. All these results suggest that impressic acid, 3α-hydroxy-lup-20(29)-en-23-oxo,28-oic acid, (20R)-3α-hydroxy-29-dimethoxylupan-23,28-dioic acid, acankoreoside F, acantrifoside A and A. koreanum may have a potential for therapeutic agents to prevent cartilage degradation possibly by inhibiting matrix protein degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acanthoic%20acid" title="acanthoic acid">acanthoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=Acanthopanax%20koreanum" title=" Acanthopanax koreanum"> Acanthopanax koreanum</a>, <a href="https://publications.waset.org/abstracts/search?q=cartilage" title=" cartilage"> cartilage</a>, <a href="https://publications.waset.org/abstracts/search?q=impressic%20acid" title=" impressic acid"> impressic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20metalloproteinase" title=" matrix metalloproteinase"> matrix metalloproteinase</a> </p> <a href="https://publications.waset.org/abstracts/57571/acanthopanax-koreanum-and-major-ingredient-impressic-acid-possess-matrix-metalloproteinase-13-down-regulating-capacity-and-protect-cartilage-destruction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57571.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">361</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">2484</span> Improved Performance Scheme for Joint Transmission in Downlink Coordinated Multi-Point Transmission</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Su%20Ryu">Young-Su Ryu</a>, <a href="https://publications.waset.org/abstracts/search?q=Su-Hyun%20Jung"> Su-Hyun Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Myoung-Jin%20Kim"> Myoung-Jin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung-Kyu%20Song"> Hyoung-Kyu Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, improved performance scheme for joint transmission is proposed in downlink (DL) coordinated multi-point(CoMP) in case of constraint transmission power.

However, the performance of communication is not sufficiently improved since the distance between each base station and a user is still distant. Therefore, we propose a scheme that the relays are used and the cooperative scheme is adaptively applied according to the user location.

Therefore, there is a need to develop PCM which is less impact to environments. Usually, UM resin is known to be harmless to the environment. Accordingly, in this paper, the properties of the PCM using UM resin were studied. The general cement mortar and UM resin was mixed in the specified ratio. A certain percentage of PVA fibers, steel fibers and mixed fibers (PVA fiber and steel fiber) were added to enhance the flexural strength. The flexural tests were performed in order to investigate the flexural strength of each PCM.

Although some studies suggest that young learners can collaborate and support each other, other studies indicate that young learners may lack the ability to work together and support one another when interacting on classroom tasks. Moreover, despite the claims that peer collaboration is conducive to learning, studies have not paid enough attention to the “how” to enhance peer collaboration on classroom tasks. To fill this gap, this “how-to” article proposes that teaching young learners how to work together is a powerful pedagogical tool that can greatly improve collaborative behavior and a sense of mutuality among young learners. This article will pay particular attention to primary schools and the context of English as a foreign language. It will first review literature related to patterns of interaction and peer support conducted in the cognitive and sociocultural framework. It will then address what it actually means to collaborate. At the heart of the article, it will discuss some practical pedagogical ideas for language teachers, which entail teaching collaborative principles and strategies that will help their students to support each other and engage in communication with each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=young%20learners" title="young learners">young learners</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20collaboration" title=" peer collaboration"> peer collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20interaction" title=" peer interaction"> peer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20support" title=" peer support"> peer support</a>, <a href="https://publications.waset.org/abstracts/search?q=patterns%20of%20interaction" title=" patterns of interaction"> patterns of interaction</a> </p> <a href="https://publications.waset.org/abstracts/147980/teaching-young-learners-how-to-work-together-pedagogical-ideas-for-language-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147980.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">157</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">2480</span> Optimal Rotor Design of an 150kW-Class IPMSM through the 3D Voltage-Inductance Map Analysis Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eung-Seok%20Park">Eung-Seok Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Chul%20Jeong"> Tae-Chul Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Jong%20Park"> Hyun-Jong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Woo%20Jun"> Hyun-Woo Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong-Woo%20Kang"> Dong-Woo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Lee"> Ju Lee </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This presents a methodology to determine detail design directions of an 150kW-class IPMSM (interior permanent magnet synchronous motor) and its detail design.

Developing an educational app on an Ipad like tablet, especially for a young child (age 3-5) requires an optimal level of challenge to continuously attract children’s attention and obtain an educational effect. Adaptive difficulty adjustment, which could dynamically set the difficulty in the challenge according to children’s performance, seems to be a good solution. Since space concept plays an important role in young children’s cognitive development, we made an experimental comparison in a French kindergarten between one group of 23 children using an educational app ‘Debout Ludo’ with adaptive difficulty settings and another group of 20 children using the previous version of ‘Debout Ludo’ with a classic incremental difficulty adjustment. The experiment results of spatial problem solving indicated that a significantly higher learning outcome was acquired by the young children who used the adaptive version of the app. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20difficulty" title="adaptive difficulty">adaptive difficulty</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20problem%20solving" title=" spatial problem solving"> spatial problem solving</a>, <a href="https://publications.waset.org/abstracts/search?q=tactile%20tablet" title=" tactile tablet"> tactile tablet</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20children" title=" young children"> young children</a> </p> <a href="https://publications.waset.org/abstracts/43918/the-effectiveness-of-adaptive-difficulty-adjustment-in-touch-tablet-app-on-young-childrens-spatial-problem-solving-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43918.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">444</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">2478</span> Visualization of the Mobility Patterns of Public Bike Sharing System in Seoul</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Hyun%20Seo">Young-Hyun Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hosuk%20Shin"> Hosuk Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun-Hak%20Lee"> Eun-Hak Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Young%20Kho"> Seung-Young Kho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study analyzed and visualized the rental and return data of the public bike sharing system in Seoul, Ttareungyi, from September 2015 to October 2017. With the surge of system users, the number of times of collection and distribution in 2017 increased by three times compared to 2016. The city plans to deploy about 20,000 public bicycles by the end of 2017 to expand the system. Based on about 3.3 million historical data, we calculated the average trip time and the number of trips from one station to another station. The mobility patterns between stations are graphically displayed using R and Tableau. Demand for public bike sharing system is heavily influenced by day and weather. As a result of plotting the number of rentals and returns of some stations on weekdays and weekends at intervals of one hour, there was a difference in rental patterns. As a result of analysis of the rental and return patterns by time of day, there were a lot of returns at the morning peak and more rentals at the afternoon peak at the center of the city. It means that stock of bikes varies largely in the time zone and public bikes should be rebalanced timely. The result of this study can be applied as a primary data to construct the demand forecasting function of the station when establishing the rebalancing strategy of the public bicycle. <p
