The Role of Switching Costs in O2O Platforms: Antecedents and Consequences
Minghui Kang,Yiwen Gao,Tao Wang,Meng Wang 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.3
Online to offline is a new business mode combining the online shopping and the front line transactions. No previous studies have simultaneously examined these variables as antecedents of e-loyalty intention or the possible relationships among them within O2O platform. Our paper has examined the effects of inertia; perceived ease of use, customization and quality of offering on the consumer’s switching costs. These findings provide a theoretical foundation for academics and also practical guidelines for service providers in dealing with the promotion of loyalty at O2O platforms.

Han, Yiwen,Kang, Wanmo,Thorne, James,Song, Youngkeun ELSEVIER SCIENCE B.V. AMSTERDAM 2019 URBAN FORESTRY AND URBAN GREENING Vol.41 No.-
<P><B>Abstract</B></P> <P>The fragmentation of natural habitats by urbanization often results in small and isolated remnants that lead to the degeneration of ecosystem services (ESs) and a loss of biodiversity. However, our understanding of the effects of landscape patterns on the provisioning of ESs in urban areas remains limited, as few studies have distinguished historical forest remnants (HFRs) from recently established habitats or have quantified changes in ESs due to HFRs. This study measured changes in the extent of forest ecosystems and the role played by HFRs in generating ESs in the human-dominated modernized landscape of Seoul, Republic of Korea. We use the spatial configuration of habitats to measure an index of habitat quality as an ES for a target conservation objective of general terrestrial biodiversity. Land-cover maps from two periods were used to identify 37 isolated patches within current parks with HFRs. Then landscape patterns and modeled habitat quality and habitat units (HUs) were quantified. Pearson correlation coefficients and forward stepwise multiple regression were used to examine the landscape metrics combined with HUs to explore key indicators that affect the HUs-value of HFRs. A 35.31% decline in total HUs was observed due to a significant decline in total forest area; however, the HUs of the HFRs increased by 0.5%. The shapes of current forests may positively affect the biodiversity of HFRs, whereas the area of newly formed habitats may negatively affect biodiversity in our modeling results. Thus, the careful design of newly formed habitats during city planning should include the preservation of historical remnants.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The historical forest remnants within current forests habitats were identified at current parks. </LI> <LI> A joint analysis of changes of landscape pattern and habitat quality values was approached. </LI> <LI> The four key landscape metrics of current forests habitats played a significant role in affecting the habitat quality in historical forest remnants. </LI> <LI> The careful design of newly formed habitats during city planning should include the preservation of historical remnants. </LI> </UL> </P>

재한 중국인 유학생의 실패공포와 내현적 자기애가 학업지연행동에 미치는 영향
곽이문(Guo Yiwen),허비비( Xu Feifei),임현수(Lim Hyunsu),강진령(Kang, Jinryung) 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.23
본 연구는 재한 중국인 유학생의 학업지연행동에 영향을 미치는 개인 내적 요인에 대해 탐색하는데 목적을 갖고 있다. 이를 위해 2016년 2월부터 3월에 걸쳐 서울특별시에 소재한 4년제 2개 대학의 중국인 유학생 214명을 대상으로 설문조사를 실시하 였으며, 회수된 자료는 SPSS 23.0을 이용하여 빈도분석 및 Pearson상관분석, 성별에 따른 차이를 보기위한 t-검증, 그리고 다중회귀분석을 실시하였다. 연구결과는 다음과 같다. 첫째, 재한 중국인 유학생의 실패공포, 내현적 자기애와 학업지연행동은 유의한 정적 상관을 나타냈다. 둘째, 재한 중국인 유학생의 실패공포와 내현적 자기애는 학업지연행동에 정적 영향을 미치는 것으로 나타났다. 셋째, 재한 중국인 여학생이 남학생보다 실패공포, 내현적 자기애, 그리고 학업지연행동의 정도가 전체적으로 높은 결과를 나타냈다. 이와 같은 결과는 실패공포와 내현적 자기애가 학업지연행동에 어떤 영향을 미치는지 과정을 설명하고 성별에 따른 차이를 확인하였다는 것, 그리고 중국인 유학생의 심리적 특성에 맞는 적합한 교육 및 학업상담을 제공하는 기초자료로써 본 연구의 의의가 있다. The purpose of the study is to find out the effects of fear of failure and convert narcissism on academic procrastination among Chinese students who study in Korean university. For this purpose, 214 Chinese student’s survey results were collected from whom studying at four-year universities two in Seoul. And statistical analysis was carried out using SPSS 23.0. From the beginning, both independent sample T-test and Pearson Correlation Coefficient (PCC) have been utilized to study the gender differences and correlation of fear of failure, covert narcissism of Chinese students, respectively. At the end, multiple regression analysis is used to validate the impact from fear of failure and covert narcissism on academic procrastination. The results of the study are as follows: Firstly, the research results indicates the meaningful correlations among fear of failure, convert narcissism and academic procrastination of Chinese students. Secondly, the research results of impact from fear of failure and convert narcissism on academic procrastination of Chinese students shows that the fear of failure and the covert narcissism both have positively impact on academic procrastination. Last but not least, according to the gender difference study, following meaningful results are achieved: Female students tend to have slightly heavier behavior in academic procrastination than male students and there are relatively more female students than male students in each sub factors of fear of failure and covert narcissism. based on these results, the importance and necessary is obvious to conduct a research according impact on academic procrastination from fear of failure and convert narcissism. And this study is meaningful as a basic data to provide appropriate education and psychological counseling for Chinese students who study in Korea.

ZntR positively regulates T6SS4 expression in Yersinia pseudotuberculosis
Tietao Wang,Keqi Chen,Fen Gao,Yiwen Kang,Muhammad Tausif Chaudhry,Zhuo Wang,Yao Wang,Xihui Shen 한국미생물학회 2017 The journal of microbiology Vol.55 No.6
The type VI secretion system (T6SS) is a widespread and versatile protein secretion system found in most Gram- negative bacteria. Studies of T6SS have mainly focused on its role in virulence toward host cells and inter-bacterial inter-actions, but studies have also shown that T6SS4 in Yersinia pseudotuberculosis participates in the acquisition of zinc ions to alleviate the accumulation of hydroxyl radicals induced by multiple stressors. Here, by comparing the gene expression patterns of wild-type and zntR mutant Y. pseudotubercu-losis cells using RNA-seq analysis, T6SS4 and 17 other bio-logical processes were found to be regulated by ZntR. T6SS4 was positively regulated by ZntR in Y. pseudotuberculosis, and further investigation demonstrated that ZntR regulates T6SS4 by directly binding to its promoter region. T6SS4 ex-pression is regulated by zinc via ZntR, which maintains in-tracellular zinc homeostasis and controls the concentration of reactive oxygen species to prevent bacterial death under oxidative stress. This study provides new insights into the regulation of T6SS4 by a zinc-dependent transcriptional regu-lator, and it provides a foundation for further investigation of the mechanism of zinc transport by T6SS.
