Parameterization has been one of very important research subjects in several application areas including computer graphics. In the parameterization research, the problem of mapping 3D polygonal model to 2D plane has been studied frequently, but the previous methods often fail to handle complicated shapes of polygonal surfaces effectively as well as entail distortion between the 3D and 2D spaces. Several attempts have been made especially to reduce such distortion, but they often suffer from the problem when an arbitrary rectangular surface region on 3D model is locally parameterized. In this paper, we propose a new local parameterization scheme based on the projection level set method. This technique generates a series of equi-distanced curves on the surface region of interest, which are then used to generate effective local parameterization information. In this paper, we explain the new technique in detail and show its effectiveness by demonstrating experimental results.

본 연구에서는 IT인력을 대상으로 개인특성과 조직특성이 경력만족 및 경력전망, 그리고 경력몰입에 미치는 영향과 경력만족 및 경력전망의 매개효과를 연구하였다. 개인특성에는 성장욕구강도, 자아존중감, 경력계획을, 조직특성에는 분배공정성, 성장기회제공, 경력관리를 선정하였으며 매개변수로는 경력만족 및 경력전망을 선정하였다. IT 인력의 경력몰입을 실증적으로 연구하기 위해 국내 IT관련 업체에 종사하고 있는 개발자 및 전산실 직원들을 대상으로 설문조사를 실시하였다. 설문지는 총 220부를 배포하여 195부를 회수하였으며 회수된 설문지를 토대로 요인분석과 회귀분석을 이용하여 가설을 검증한 결과는 다음과 같다. 첫째, 경력성공 변수인 경력만족과 경력전망은 경력몰입에 유의미한 영향을 미치는 것으로 나타났다. 둘째, 개인특성 중 자아존중감이 경력만족에 가장 큰 영향을 미치는 것으로 나타났고 조직특성 중 분배공정성 및 성장기회제공 등에 대한 지각 정도가 높을수록 경력전망에 유의미한 영향을 미치는 것으로 나타났다. 셋째, 경력만족과 경력전망이 경력몰입에 미치는 매개효과를 살펴본 결과 부분적인 매개효과를 나타냈다.

The present study aims to investigate the mediating effects of social support in regard of the impacts of stress-coping styles on depression in children from multi-cultural families. In a nutshell, the findings in this study are as follows: First, the stress-coping styles of children from multi-cultural families and depression were found to be negatively related, while social support and depression were negatively correlated. Second, as for the effects of stress-coping styles in children from multi-cultural families on depression, the more passive and active stress-coping styles of children from multi-cultural families, the less their depression, behavior disorder, loss of interest, self-abasement and physical symptoms. Third, high levels of teachers' support partially mediated the relation between stress-coping styles and depression in children from multi-cultural families. This finding implies that children from multi-cultural families, who perceive high levels of peer support, cope with stress better and thus reduce depression.

This study aims to discuss how job stress of private security guards would influence organizational commitment and turnover intention, and it basically looks into mediating effects of job burnout to understand the former's effects on the latter. In order to conduct the analysis, the study selected private security guards working for security agencies located in Seoul as a research subject, and carried out a survey targeting 700 of those security guards who had been gathered by a random cluster sampling method. The survey was conducted for about four months from May of 2014 to September of the same year and with 24 samples that had not been returned or that had been observed to have some outliers excluded, a total of 676 samples were applied as final data. The study used SPSSWIN 18.0 Statistical Package for analyzing the data, and hypotheses were confirmed via a Frequency Analysis, Factor analysis, Cronbach's Alpha, Person's Correlation Analysis, regression analysis and a path analysis. Findings of the analysis reported that emotional exhaustion has partially mediating effects on relations among role conflict, role overload and organizational commitment and that role ambiguity is not significantly connected. In addition, as for a relation of role conflict and turnover intention, emotional exhaustion was turned out to have a full mediating effect on the relation. The study did not notice any significant connection between emotional exhaustion and role ambiguity. Add to that, in terms of a relation between role overload and turnover intention, emotional exhaustion appeared to have a partial mediating effect on the relation which helped a relevant hypothesis to be partly adopted. Regarding a relation of job stress with organizational commitment, according to results of a path analysis on dehumanization, dehumanization does not significantly affect a relation between role ambiguity and organizational commitment and as for role conflict and role overload, the study confirmed that they have a partially mediating effect on this relation of dehumanization with organizational commitment. The study learned then that dehumanization does not have a significant influence on a relation between role ambiguity and turnover intention. However, the study figured out that when it comes to a relation of role conflict and role overload, dehumanization has a partially mediating effect on the relation and as a consequence, a relevant hypothesis was adopted in part.

This study aimed to verify the mediating effect of hope between acculturative stress and depression of immigrant women for marriage in Chungcheongnam-do, Korea. The data were collected from 580 immigrant women for marriage and were analysed by using descriptive statistics, correlation analysis and structural equation. The main results were as follows. There was a positively direct effect between acculturative stress and depression. But hope had negatively direct effect on acculturative stress and depression. Also, the study verified that there was the mediating effect of hope between acculturative stress and depression of immigrant women. Implications for the suggestions to enhance the hope level of immigrant women and future research were discussed.

This study is to analyze the relationship between Taeoom(workplace bullying) and organizational performance and to investigate the mediating effects of organizational silence between the relationship among nurses. In order to test the causal and mediating effects, this study employs the mediation analyses with regression. The sample is 273 from A university hospital in Seoul. Based on the results, Taeoom is basically, negatively associated with organizational performance. Acquiescence silence has played a full mediating role in the relationship between Taeoom and organizational performance. That is, Taeoom is not directly associated with organizational performance; however, it has a negative effect on organizational performance through acquiescence silence. Defensive silence plays a partial mediating role in the interdependence relationship. The implications of this study are that the negative effects of Taeoom would increase organizational silence and performance directly and indirectly; therefore, it is necessary to provide institutional prevention of Taeoom.

this study aims to analyze causality on the effect of job satisfaction on vocational adaptation of ex-prisoners through empirical study and to verify the moderated effect of self-esteem and the Moderated Mediation effect of the job stress. According to the analysis, job satisfaction have a static effect on Vocational Adjustment and the self-esteem have a mediated effect in this process. also, the indirect effects of job satisfaction on vocational adaptation by self-esteem are moderated by job stress. advanced researchs study that job-related emotions affect vocational adaptation and maintenance, but psychological factors affecting vocational adaptation is not dealt with in depth, and what factors actually moderate this process is not explored in detail. also, becausea there are few studies related to the job of ex-prisoner, this study carried out full-fledged exploration and verification of it.

This study provides an approach to perform the double mediation analysis in structural equation models using the R. For this purpose, the study reviews a variety of techniques for mediation analysis, selects the bootstrapping technique as the most suitable way for performing the double mediation analysis and develops an approach for the double mediation analysis in structural equating models with the bootstrapping using the plspm which is the R package for the performing PLS path analysis. This study will be useful for the studies including the double mediation analysis in structural equation modeling, which is not supported by most of SEM packages, also will provide the knowledge base for in-depth analysis through suggesting the new mediation analysis technique using R for the researchers.
