The purpose of this study to investigate is as follows. First, this study examines the effects of WLB on organizational commitment and organizational citizenship behavior among domestic small and medium-sized company members. Second, this study examines the mediating effects of psychological safety on the WLB, and organizational commitment. Also, we will examine the mediating effects of psychological safety on the WLB, and organizational citizenship behavior. Third, the causal relationship between the dependent variables is verified. To test the hypothesis of this study, we analyze the statistics program using SPSS 25.0 and Macro Process. The results of this study through empirical research are as follows. First, WLB has a positive effect on organizational commitment and organizational citizenship behavior. Second, psychological safety was found to play a mediating role in the relationship between work-life balance and organizational commitment. Third, psychological safety was found to play a mediating role in the relationship between work-life balance and organizational citizenship behavior. Fourth, organizational commitment has a positive effect on organizational citizenship behavior.

Although the existing performance-based design method for the vertical breakwater evaluates an average sliding distance during an arbitrary time, it does not calculate the probability of the first occurrence of an event exceeding an allowable sliding distance(i.e. the first-passage probability). Designers need information about the probability that the structure is damaged for the first time for not only design but also maintenance and operation of the structure. Therefore, in this study, a time-dependent reliability design method based on a stochastic process is developed to evaluate the first-passage probability of caisson sliding. Caisson sliding can be formulated by the Poisson spike process because both occurrence time and intensity of severe waves causing caisson sliding are random processes. The occurrence rate of severe waves is expressed as a function of the distribution function of sliding distance and mean occurrence rate of severe waves. These values simulated by a performance-based design method are expressed as multivariate regression functions of design variables. As a result, because the distribution function of sliding distance and the mean occurrence rate of severe waves are expressed as functions of significant wave height, caisson width, and water depth, the first-passage probability of caisson sliding can be easily evaluated.

This study was conducted to identify the causal pathways of variables affecting life satisfaction in adolescents with disabilities to establish a basis for concrete intervention in their daily lives. This study was conducted on 239 adolescents with disabilities aged 9 to 24 years who responded to the survey on the actual conditions of people with disability in 2017. The SPSS macro process was used for analysis of the dual mediation effect. The results showed that there was a statistically significant correlation between instrumental daily life performance capacity, life satisfaction, Self-Rated Health, and participation in culture and leisure activities. It confirmed the mediating effects of Self-Rated Health and cultural leisure activities when the instrumental daily life performance capacity affected life satisfaction. This confirmed the dual mediating effect of instrumental daily life performance capacity on life satisfaction through causal pathways of Self-Rated Health and participation in cultural leisure activities. Based on the results of this study, it was possible to identify the focus of practical intervention through the identification of sequential pathways of Self-Rated Health and cultural and leisure activities on influence of instrumental daily life performance capacity and life satisfaction in adolescents with disabilities.
