The objective of the study was to analyze difference in cognitive function according to social isolation level in elderly Korean. The author classified the social isolation into the structural isolation and contact isolation. Structural isolation corresponded to the no spouse or no children and the contact isolation corresponded to the absence of contact with children, friends or social association. Author conducted multivariate regression analysis with the elderly people aged 65 years or older from the 5th wave of the Korean Longitudinal Study of Ageing data. Number of sample was 3,971. It was confirmed that the level of cognitive function was lower according to level of social isolation. It was also confirmed that friends/neighborhood isolation, and social activity isolation showed significant relationships with cognitive functions. Based on the results, author suggested that to protect the elderly from negative effects of social isolation, we needed the policy to promote elderly's the participation in social activity. The study to analyze the factors related to social isolation was also needed.

This study was performed to examine the relationship between fatigue and fatigue-regulation behavior in Hemodialysis(HD) patients. Methods: The subjects for this study were 107 patients on HD who were registered in a hospital in Seoul. The data were collected from August 2 to August 14, 2010. The collected data were analyzed by the SPSS WIN 12.0 program. Results: The mean score of fatigue was 77.1 which means their experience of high level fatigue. Frequency of the fatigue-regulation behavior and the mean of efficiency of the fatigue-regulation behavior was 8.8 and 22.8. Positive correlation was found between fatigue and fatigue-regulation behavior (r=.45, p=.000). Conclusion: It is considered that the study emphasizes for the healthcare providers to recognize fatigue as the important nursing issue for HD patients.

The rapid trends toward outsourcing have created more complex and fragmented multi-tier supply chains for Engineering, Procurement & Construction(EPC) industry. Working with suppliers and sub-suppliers requires continuous integration activities during project execution. The purpose of this study is to identify the factors influencing the performances and relationship satisfaction of second-tier suppliers participating in the project-based supply chain. This study proposes the network embeddedness, collaboration, information-sharing and flexibility as antecedents variables, and collected the survey responses from the second-tier suppliers having experiences with complex projects. The statistical results indicate that the collaboration with supply chain leading firm and first-tier supplier has significant impact on the performances and relationship satisfaction of second-tier suppliers. It was also found that the information-sharing and flexibility influence the network embeddedness as well as collaboration, and that the embeddedness have significant impact on the collaboration.

The purpose of this study is to investigate the effect of optimism on stress on happiness index. The subjects were 3 and 4 grade students who had clinical practice experience among 3 nursing students at G university, and 362 questionnaires were used as research data. The data analysis used regression analysis, SPSS macro and bootstrapping methods to examine the mediating effects of optimism on college students' stress and happiness. The results showed that stress, happiness, and optimism were significantly correlated, and stress had a direct effect on college students' happiness. In other words, the higher the level of stress, the lower the happiness index of college students. The optimism was partially mediated between stress and college students' happiness index. Therefore, in order to increase the happiness index of college students, it is necessary to develop and implement a program for happiness enhancement as one of the program strategies that can enhance stress.

Bargain position and trust are core issues in supply chain management, yet the effect of bargain position on trust remains to be undetermined. The purpose of this research is to present theoretical and methodological hurdles for the relationship among various bargain positions and trust, and develops a set of hypotheses about the asymmetric effect of bargain position on trust in supply chain network. An analytical tool to analyze nonlinear effects on a response surface is introduced. Based on the data collected through a survey of firms participating in Project Supply chain, a set of hypotheses is tested. The analysis results support the prediction that the bargain position perceived by the buyers have asymmetric effects on trust toward supplies, and provide more fine-grained accounts on the relationships among bargain power, bargain position and trust in a supply chain network.

The purpose of this study is to verify the learning effect of domestic flipped learning in meta - analysis. We collected a total of 95 studies on flipped learning effectiveness published in Korea by 2017, of which 59 are dissertations and thesis and 36 are academic papers. The results were analyzed using CMA program. First, the learning effect of flipped learning was .58, which showed that the learning effect was higher than the lecture class. Second, the effect size of cognitive, affirmative, and interpersonal domains showed significant effects of flipped learning in all three domains. Third, the learning effect of flipped learning is influenced by the type of publishing, school type, core subject, when the type of publication are dissertation and thesis, when the type of school is high school. Based on the results, this study suggested implications for the design and implementation of flipped learning in Korea.
