I have empirically investigated the relationship between work-family facilitation and perceived team performance and the moderating effect of wellness climate between work-family facilitation and perceived team performance. For testing hypothesis, hierarchical linear regression was conducted. The results of analysis are followings; hypothesis 1, work-family facilitation is positively related to perceived team performance, was significantly supported. Hypothesis 2, wellness climate moderates the association between work-family facilitation and perceived team performance. The results imply that when the HR practitioners design job and welfare program of employees should consider work-family facilitation. Additionally, to improve the performance of organization should consider not only work-family facilitation but also climate of organization supporting work-family facilitation, wellness climate.

The purpose of this study was to investigate the convergence factors affecting of physical activity level on hemodialysis patients' depression, health-related quality of life and sleep disorders. The participants were 193 hemodialysis patients undergoing hemodialysis in five hospitals in two cities. Data were analyzed by technical statistics, correlation and hierarchical regression. The results showed that depression and physical activity were negatively correlated (r = -.259, p <.01), and physical and mental health related quality of life and physical activity correlated positively (R = .273, p <.01, r = .186, p <.01), respectively. Hierarchical regression analysis showed that the higher the quality of life related to physical health, the higher the level of physical activity of hemodialysis patients (${\beta}=.22$, p <.01). Therefore, it is required to develop an intervention program to improve health-related quality of life by improving the physical activity of hemodialysis patients.

This study aims to improve the situation in which accurate job information for small and medium-sized enterprises is not known and it is difficult to identify jobs that meet the preference criteria from the perspective of the 'employer brand'. To this end, through a hierarchical regression analysis of 700 young job seekers, the factors affecting the intention to get a job centered on five value factors (Interest Value, Social Value, Economic Value, Development Value and Application Value) were identified by reflecting the brand categorization theory. As a result of the analysis, it was confirmed that young job seekers are more interested in work culture, environment, and utilization of their majors, which directly affect job seekers, rather than characteristics of companies such as talent development, products, services, and management, and are influenced by their intention to work. This suggests that the job policy for SMEs needs to be changed from the existing quantitative support-centered to a qualitative improvement that strengthens the use of platform-centered job information.

The object of this study is through an empirical analysis, how cultural capital at the individual level and social welfare expenditure at the national level affect the life satisfaction of the elderly. In this study method, a Hierarchical Linear Model(HLM) analysis was performed on 3,297 elderly people aged 65 and older and 9 OECD countries. As a result of analysis, first, it was confirmed that life satisfaction and social class had a significant effect. Therefore, in to increase the satisfaction of the life of the elderly, policy and practical intervention measures that can narrow the gap between social classes should be prepared. Second, the old-age pension and survivor's pension had no significant effect on life satisfaction. However, as a result of the interaction, social class has a positive effect on life satisfaction, and it was confirmed that the lower the income inequality, the more positive the life satisfaction was. In conclusion, this implies that both individuals and countries should make efforts to variously increase the life satisfaction of the elderly.
