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. In addition, previous studies analyzed mediating effects or moderating effects, but this is the first study to identify the moderated mediating effects of safety behavior through safety culture. In other words, it has originality in terms of research methodology.

본 연구는 기혼자의 결혼불만족이 외로움을 통해 SNS중독에 미치는 매개효과가 연구 대상자가 지각하는 사회자본의 크기 및 구성 장면에 따라 차이를 보이는 지, 즉 조절된 매개효과를 나타내는 지 확인하고자 하였다. 연구대상은 전국 20~40대 성인 기혼 남 녀 714명이다. 온라인 전문 리서치회사에 자료 조사를 의뢰해 인구통계학적 비례에 따른 할당 표집을 기본으로 임의 선택의 과정을 거쳐, 연구자료를 수집하였다. 본 연구모형 검증을 위해 구조방정식을 사용한 조절된 매개효과 분석 절차를 따랐다. 주요 분석 결과는 다음과 같다. 첫째, 외로움은 기혼 성인의 결혼불만족과 SNS 중독 사이를 매개하는 것으로 확인되었다. 특히, 독립변수와 종속변수 간 관계가 비유의적인 것으로 나타나, 매개효과의 완전 혹은 부분 여부를 경쟁모형 비료를 통해 확인한 결과, $x^2$을 비롯한 다양한 적합도 지수가 상대적으로 양호한 완전매개 모형을 최종적으로 채택하였다. 둘째, 결혼불만족과 외로움, SNS 중독 간 매개모형에서 사회자본 크기가 조절된 매개효과를 나타냈다. 구체적인 경로를 살펴보면, 자신의 사회자본을 상대적으로 크게 인식하는 집단이 작게 인식하는 집단에 비해 외로움에서 SNS중독에 이르는 과정과 결혼불만족에서 SNS중독에 이르는 경로의 효과 크기를 더 크게 인식했다. 이와 함께, 사회자본 형태별로 비중 차이에 따른 조절된 매개효과도 확인했다. 즉, 사회자본의 형태를 면대면 그리고 SNS 장면으로 구분해 각각의 비중 차이에 따라 면대면 우세, SNS우세 집단으로 구분해 매개모형의 다집단분석을 실시한 결과 각 경로 간 효과크기에 차이가 나타났다. 자신의 사회자본이 면대면 보다는 SNS 온라인 상에 더 편중되었다고 느끼는 집단에서는 외로움이 SNS 중독에 미치는 영향을 더 크게 느끼는 것으로 나타났다. 이는 면 대 면과 SNS 사회자본 사이의 불균형이 결혼불만족과 외로움, SNS 중독 간의 관계에서 위험요인으로 작용함을 의미한다. 이러한 연구결과를 토대로 기혼 성인들의 SNS 중독에 대처하기 위한 정책적, 실천적 대응방안을 제언하였다.

Purpose: This paper investigated the effects of issue leadership on employees' work performance. It also explored the mediating role of job challenge in the above relationship. We also tested the moderating effect of psychological ownership in the relationship between issue leadership and job challenge. Finally, this paper examined the moderated mediation effect of psychological ownership in the course of affecting issue leadership on work performance via job challenge. Methods: This paper used a cross-sectional design with questionnaires administered to 390 employees working in Korean firms. It applied an hierarchical and multi-regression analysis by using SPSS 22.0 and Hayes' Macro Process to test the proposed hypotheses including a moderated mediation model. Results: As a result of the analysis, first, it was found that the issue leadership had a positive effect on the work performance. Second, it was also found that issue leadership had a positive effect on the job challenge. In addition, job challenge was found to positive mediating effect in the relationship between issue leadership and work performance. Third, we found that the psychological ownership positively moderated the relationship between issue leadership and job challenge. Finally, the moderated mediating effect was found by confirming that the higher the degree of psychological ownership, the stronger the effect of issue leadership on the work performance via job challenge. Conclusion: This paper contributes to the leadership and work performance studies by identifying the role of issue leadership enhancing employee work performance while confirming connection mechanism and boundary conditions strengthening the positive effect of issue leadership on employee work performance.

Objective: This study aimed to investigate the moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation on the relationship between children's screen media time and executive function difficulties. Methods: A total of 693 parents of children aged 5~6 years participated in this study and were asked to answer all survey questions. The data were analyzed by descriptive statistics and correlation analysis using SPSS 27.0. Model 11 of PROCESS macro 4.3 was used to examine the moderated-moderated mediation model. Children's gender, age, childcare enrollment status, and household income were included in the analyses as covariates. Results: The moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation were found to be significant. Specifically, bedtime mediated the relationship between screen media time and executive function difficulties only when parents did not appropriately implement restrictive mediation and children freely selected media content. Conclusion/Implications: It is recommended that parents understand the importance of implementing restrictive media mediation and selecting appropriate media contents for their child to prevent executive function difficulties in early childhood. Also, child education or day-care centers should offer education program about appropriate media use to reach more parents.

This study examined the moderated mediating impact of entrapment and emotional support from peers in the relationship between academic stress and suicidal ideation among middle-school students. The participants consisted of 214 middle-school students in the first to third grades from four middle schools located in Seoul, Gyeong-gi, Chun-cheon, and Jeonnam. The data were analyzed using descriptive statistics, Pearson's correlation coefficients, and the Process Macro Model versions 4, 1, and 14. The results of this study were as follows. First, academic stress did not directly influence suicidal ideation; however, entrapment mediated the relationship between academic stress and suicidal ideation. Second, emotional support from peers moderated the mediating effect of entrapment in the aforementioned relationship. This means that if students perceived emotional support from peers, then academic stress had a smaller impact on suicidal ideation through entrapment. These findings highlight the importance of decreasing levels of academic stress and entrapment to prevent suicidal ideation among middle-school students. They also suggest that enhancing students' emotional support networks with their peers could be an effective way of reducing suicidal ideation when students feel high levels of entrapment and academic stress.

Based on the stimulus-organism-response model, this study investigated the effects of three types of green performance appeals (i.e., before-, after-, and before/after-appeals) on consumer word of mouth (WOM) mediated by anticipatory hope. As the degree of consumer susceptibility to advertising varies by individual, individual perceived consumer effectiveness (PCE) was examined as a moderated mediating variable. A total of 191 responses were analyzed using SPSS 27.0 for analysis of variance and PROCESS procedure. Results showed the mediating role of anticipatory hope between advertising appeals and WOM: participants reported greater anticipatory hope when they viewed the advertisement with after- and before/after-appeals. This mediation was moderated by participants' PCE. The effect of green performance appeals on WOM was mediated by participants' anticipatory hope when their PCE was low; however, when participants' PCE was high, the mediation was not significant. The findings show that advertising appeals highlighting the effectiveness of green performance can attract consumers who do not believe that product consumption affects a sustainable environment and spread WOM. This research provides insights to fashion brands by suggesting effective green advertising strategies that can increase consumers' voluntary information-sharing behavior.

The purpose of this study was to examine the mediating effect of middle school students'self-deprecation in the relationship between upward social comparison in social network service (SNS) and depression and the moderated mediating effect of cognitive flexibility. The participants were 288 middle school students, in the first to third grades from four middle schools located in Seoul, Gyeong-gi, and Jeonnam. The date were analyzed with descriptive statistics, Pearson's correlation coefficients and the Process Macro Model 4, 1, and 14. The results of this study are as follows. First, an upward comparison in SNS has a significant positive influence on students'depression, and students' self-deprecation of students mediated the relation between two. Second, the level of control, which is a sub-factor of cognitive flexibility, moderated the mediating effect of self-deprecation. That is, if students are more likely to perceive difficult situations as controllable, upward social comparison in SNS mediated by self-deprecation has smaller effect on depression. Based on these results, we suggest practical interventions to reduce depression among middle school students by decreasing upward social comparison in SNS and self-deprecation. In addition, helping students perceive difficult situations as controllable could be another effective way of reducing depression among those students who have a high level of self-deprecation in upward social comparison in SNS.
