Difference of Risk-relievers between High Risk and Low Risk in Online Purchasing

Hua-Long Fang,Sun-Dong Kwon,Kee-Su Bae 한국데이타베이스학회 2014 Journal of information technology applications & m Vol.21 No.3

The Online business model for purchasing agent service is getting more popular. However, consumers perceive more risk when buying products from foreign online purchasing agents (FOPA) than from common online sellers (COS). This study focuses on finding out how consumers manage risk when they perceive risk and what different risk-reliever strategies they use when buying from high-risk FOPA and low-risk COS. This study has proved the following two. First, when consumers perceive risk at online purchasing, they tend to select risk-reliever strategies, such as the use of communication media, online assurance mark, seller’s record, and secure payment to mitigate risk. With the application of those risk-reliever strategies, they built trust with the seller. Second, risk-perception of FOPA influences usage of communication media and check of online assurance mark more strongly than that of COS. On the contrary, risk-perception of COS influences the check of seller record more strongly than that of FOPA. This study helps to explain why FOPA is proliferating, despite its inherent high risk due to the fact that buyers and sellers are separated in time and space and that buyers and sellers have different social and cultural backgrounds. This study also helps managers of E-commerce to relieve consumer’s risk-perception and to build trust.

A Fast Snake Algorithm for Tracking Multiple Objects

Fang, Hua,Kim, Jeong-Woo,Jang, Jong-Whan Korea Information Processing Society 2011 Journal of information processing systems Vol.7 No.3

A Snake is an active contour for representing object contours. Traditional snake algorithms are often used to represent the contour of a single object. However, if there is more than one object in the image, the snake model must be adaptive to determine the corresponding contour of each object. Also, the previous initialized snake contours risk getting the wrong results when tracking multiple objects in successive frames due to the weak topology changes. To overcome this problem, in this paper, we present a new snake method for efficiently tracking contours of multiple objects. Our proposed algorithm can provide a straightforward approach for snake contour rapid splitting and connection, which usually cannot be gracefully handled by traditional snakes. Experimental results of various test sequence images with multiple objects have shown good performance, which proves that the proposed method is both effective and accurate.

The effect of a national reading policy on fourth graders’ reading achievement in Taiwan

Fang-Hua Jhang 한국교육개발원 2017 KEDI Journal of Educational Policy Vol.14 No.1

To enhance students’ reading achievement, the Ministry of in Taiwan designed a reading policy, the “Happy Reading 101 Program” (HR101P), based on school contexts and school process factors. This study describes features inherent in the HR101P and evaluates the intervention effect of the program in terms of school context and school process factors. Findings indicate only one component contained in the HR101P―enriching teachers’ knowledge―to be significantly associated with reading achievement. Prior to the implementation of the program, the interaction effect between school-level teacher professional development (TPD) and student-level reading activities was significant. Results of a multilevel propensity score method suggest that implementation of the HR101P contributes to the progress in Taiwan of the Progress in International Reading Literacy Study 2011.

Explaining the immigrant-native gap in parental involvement in Taiwan: the role of parents’ education and students’ prior achievement

Fang-Hua Jhang 서울대학교 교육연구소 2019 Asia Pacific Education Review Vol.20 No.1

This study examines whether parents’ education and students’ previous achievement affected parental involvement and whether they mediated differences in parental involvement between new immigrant and native parents in Taiwan. Two dimensions of parental involvement were measured: parent–child discussion and school-based involvement. The sample comprised 582 new immigrant parents and 8228 native parents whose children are fourth graders. This study analyzed two-wave data by using structural equation modeling. Results revealed that both parents’ education and students’ prior achievement significantly increased parent–child discussion, but did not affect school-based involvement. In mediation analyses, all three indirect effects on parent–child discussion appeared to be significant. The results indicate that the association between immigrant status and parent–child discussion is partially mediated by parents’ education rather than by students’ prior achievement. To narrow the immigrant-native gap in home discussion, results suggest that encouraging new immigrants to return to school, regardless of whether they obtain a degree, may be a promising approach.

Molecular dynamics study of the shear strength and fracture behavior of nanoporous graphene membranes

Te-Hua Fang,Zhe-Wei Lee,Win-Jin Chang 한국물리학회 2017 Current Applied Physics Vol.17 No.10

We perform molecular dynamics (MD) simulations to study the structural response and fracture characteristics of nanoporous graphene (NPG) membranes subjected to shear loading. The effects of porosity, temperature, and shear velocity on the mechanical responses of NPG membranes are examined. The results show that the wrinkling of the membrane becomes more obvious with increasing strain. Fractures occur around holes on the long diagonal of the NPG parallelogram, and fracture stress in the NPG membrane decreases with increasing porosity. In addition, the effect of shear velocity on the shear modulus decreases with increasing porosity. The fracture strain of NPG membranes with different porosities obviously decreases with increasing temperature. The results enhance our understanding of the shear mechanical properties of NPG membranes and are helpful for the design and application of highperformance NPG membranes.

연변지역 ‘귀환’ 조선족 창업과정 사례와 정책과제

방미화 ( Fang Mei-hua ) 인하대학교 한국학연구소 2018 한국학연구 Vol.0 No.51

본 연구는 연변지역 귀환 조선족 창업 활성화를 위하여 현재 창업을 진행하고 있는 10명의 조선족 귀환창업자들의 창업과정에 대한 심층면접을 통해 그들이 창업 및 운영과정에서 겪는 공통적인 애로사항을 파악하여 그들로 하여금 연변지역에 성공적으로 재정착 할 수 있도록 당면한 정책적 과제를 제시했다. 사례가 제한적이나, 각각의 사례에 대한 세밀한 분석을 통해 현 귀환창업정책의 문제점을 도출하고 실제 연변지역 조선족 귀환창업자들의 창업활동에 맞는 제도가 만들어지도록 정책과제를 제시하였다. 구체적으로 정부는 투자자금이 많은 항목, 큰 사업만을 중시할 것이 아니라, 영세자영업자들의 창업 상황도 잘 파악하여야 하며, 그들의 실정에 맞게 정책을 제정해야 할 것이다. 그리고 정부 차원에서 창업자들에게 경제적 안목, 경영지식, 경영철학 등을 전수하는 전문 기구를 설치하여 창업자들로 하여금 급격히 변화하는 시장 형세에 직면하여 어떤 방법들로 위기를 모면하고 성공으로 나아갈 것인지를 제때에 터득할 수 있도록 해야 한다. 뿐만 아니라, 장기적인 인력 부족을 해결하는 방법을 모색할 필요가 있으며, 정부 차원에서 귀환이주자를 대상으로 하는 단체를 결성하여 그들의 상황에 대해 세밀하게 조사하고 파악하여 개개인들의 상황에 맞게 창업지도를 해주는 자문 집단을 결성하는 것이 필요하다고 본다. This study shows that to enliven Chinese-Korean start up business activities in Yanbian area, via in-depth interview 10 Chinese-Korean entrepreneurs who returned to Yanbian and starting business to understand their concerns, activities during startup and operating their business, so that they can successfully relocate in Yanbian area, and put forward current policy issues. Although it is a small number of specimens, but through detailed analysis of the specimens, it finds out the issues of the policy of “Relocate in Yanbian to start a business” and put forward the policy topic for “Relocate in Yanbian to start a business.”
