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.

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.
