Purpose - This study aims to examine the relationships between the acceptance of the 4th industrial revolution logistics technology, logistics safety behavior, and logistics safety performance, as well as the moderated mediating effects of logistics safety behavior through safety culture in Korea. Design/methodology - Research models and hypotheses were established based on prior research related to the 4th industrial revolution logistics technology, logistics safety, and logistics performance. The survey was conducted on the employees of logistics companies, and reliability analysis, confirmatory factor analysis, discriminant validity analysis, structural equation model analysis, and mediating effect analysis were performed. In addition, the moderated mediating effect analysis applying SPSS Process Model No. 7 was conducted. Findings - Usefulness and sociality of the acceptance of the 4th industrial revolution logistics technology had a significant effect on logistics safety behavior. Ease of use, sociality, and efficiency had meaningful effect on logistics safety performance. And in the relationships between the acceptance of logistics technology and logistics safety performance, logistics safety behavior had a significant mediating effect. But the moderated mediating effect of safety behavior through safety culture was not significant. Logistics companies can improve logistics safety performance through the utilization of new logistics technologies such as intelligent logistics robots, autonomous driving technology, and artificial intelligence, etc. Originality/value - This is the first study to analyze the relationships between the acceptance of logistics technology in the 4th industrial revolution and logistics safety.

This study was carried out to examine whether the moderated mediating effect of SNS addiction resulting from marital dissatisfaction and loneliness is influenced by gender or size and composition of social capital. 714 married men and women in their 20's to 40's were participated in this study. The data were collected by online research center with quota sampling based on demographical proportion. To analyze this research model, the moderated mediating effect utilizing structural equation was used. The results of this study were summarized as follows. First, it is verified that the loneliness moderated between marital dissatisfaction and SNS addiction. Since the relationship between independent and dependent variable is insignificant, comparison of competition model was able to determine if mediating effect was fully or partially shown. As a result, the complete mediated model was ultimately chosen because its various goodness-of-fit index including $x^2$ performed fairly well. Second, the mediating effect which moderates social capital size was presented in the mediated model between the marital dissatisfaction, loneliness and SNS addiction. Specifically, It implies that group who recognizes their social capital big recognizes the route and effect size more than that who considers their social capital small. And the moderated mediating effect depending on different type of social capital among the marital dissatisfaction and loneliness and between SNS addiction was substantiated. It implies that disequilibration of SNS social capital in face-to-face sphere and in online acted as a danger fact with respect to the marital dissatisfaction, loneliness and SNS addiction. The implications of these findings were discussed, and directions for future studies were also proposed.

We aimed to verify the mediating effect of depression on the relationship between burnout and flourishing, and the moderated mediating effect of psychological detachment on the mediating relationship. An online survey was conducted with 300 workers, and the results are as follows. First, significant correlations are found among burnout, depression, flourishing, and psychological detachment. Second, the mediating effect of depression on the relationship between burnout and flourishing was verified. Third, the moderated mediating effect of psychological detachment on the mediating relationship verified. Considering the successive effects of burnout on depression and the loss of flourishing, the necessity of efficient management of burnout became evident. Moreover, the moderating role of psychological detachment implies that the effect of burnout can be reduced to some extent through individual and/or organizational efforts for psychological detachment. It seems necessary to verify the moderating effect in more detail through experimental research in the future.

The study examined the mediating effect of internalized shame on the relationship between affiliate stigma and interpersonal anxiety among adolescents with siblings who had autism spectrum disorder (ASD) and the moderated mediating effect of mother-adolescent communication openness. The participants consisted of 139 adolescents (boys 48.9%, high-school students 79.8%) who had siblings with ASD. Interpersonal anxiety, affiliate stigma, internalized shame, and mother-adolescent communication openness were measured using the Social Anxiety Scale for Adolescents (La Greca & Lopez, 1998), the Affiliate Stigma Scale (Mak & Cheung, 2008), the Internalized Shame Scale (Cook, 1988), and the Parent-Adolescent Communication Scale (Barnes & Olson, 1982), respectively. The data were analyzed using descriptive statistics and Pearson's correlation coefficients. Process Macro Models 4 and 7 were used to examine the mediating effect and the moderated mediating effect. The results indicated that internalized shame mediated the effect of affiliate stigma on interpersonal anxiety among adolescents who had siblings with ASD. However, there was no significant moderated mediating effect of mother-adolescent communication openness on the relationship between affiliate stigma, internalized shame and interpersonal anxiety. These findings suggest that it is necessary to improve social awareness of individuals with ASD and their family members to prevent adolescents who have siblings with ASD from having affiliate stigma and to help them reduce interpersonal anxiety. The results also highlight the importance of counseling programs for adolescents with siblings with ASD as a way of preventing or alleviating their interpersonal anxiety by reducing internalized shame, even where they experience affiliate stigma.
