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.

Although brand love is a major interest in global business, very little is known about how the effects of brand love are affected by relevant constructs. This study examines how the brand love-loyalty link is moderated by shopping value (hedonic vs. utilitarian) and how the moderated moderation effect of gender difference influences the consumer-brand relationship. Based on a unique dataset of 254 Chinese consumers of Korean cosmetic brands in China, we tested our proposed hypotheses using Regression PROCESS macro (model = 3). One of our novel findings is that brand love has a positive influence on brand loyalty. However, this relationship is sensitive to moderators. Regarding the brand love-loyalty linkage, consumers who seek hedonic shopping value is higher than consumers who seek utilitarian shopping value. In particular, female consumers are more passionate and loyal than male consumers. Finally, male consumers seeking hedonic shopping value feature greater brand love-loyal linkage than other consumers; however, this effect is very limited.

This study explored the influence of two types of conflict(task and relationship conflict) on group creativity and tested this model with a sample of 58 teams. Relationship conflict negatively influenced group creativity but, task conflict did not show the effects on group creativity. Specifically we found the moderating effects of supportive leadership and communication. Supportive leadership style moderated positively both task conflict and relationship conflict on group creativity. But controlling leadership styled moderated negatively relationship conflict and group creativity. Finally the relationship between task conflict and group creativity was moderated by communication. Overall, we suggest conflict is one of the important group process to boost group creativity and supportive leadership and communication are the important moderators to manage conflict successfully and effectively.

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.

This study examined how the relationship between grandmother-adult child solidarity, caregiving satisfaction, and grandmother's child-rearing role varies according to the relation with the grandchild. Mediation effects and moderated mediation effects were analyzed to investigate the relationship between these variables. The participants were 295 grandmothers raising preschool-aged grandchildren in the Seoul and Gyeonggi areas. Data was analyzed using SPSS 23.0 and PROCESS macro, performing correlation analysis and hierarchical regression analysis. The statistical significance of the indirect effect was examined using a bootstrapping procedure. The results are as follows. First, grandmother-adult child solidarity directly affects the grandmother's child-rearing role. Second, grandmother-adult child solidarity indirectly affects the grandmother's child-rearing role through caregiving satisfaction. Third, the direct and indirect effects of grandmother-adult child solidarity on the grandmother's child-rearing role are moderated by the relation with the grandchild. The direct effect of grandmother-adult child solidarity on grandmother's child-rearing role was therefore shown to be significant on the maternal grandmother. Fourth, the indirect effect of grandmother-adult child solidarity on the grandmother's child-rearing role through caregiving satisfaction was shown to be significant on the paternal grandmother. Based on the results of this study, we discussed ways to strengthen the capacity of co-parenting between grandparents and adult children.

This study focuses on the influence of followership on leadership and empowerment, and to verify based on the control variables taken in IT SME's to enhance competitiveness through innovation and improvement plan that have been taken. Because there can be a lot of information to be taken, the laws of Moderated Regression Multiple analysis(MMR) were used. Amos, due to the moderating effect of Structural Equation Modeling(SEM) has been employed to re-verify the results seen with Moderated Regression Multiple analysis. The paper focuses on determining whether transformational leadership or transactional leadership is effective as shown by the levels of empowerment derived from these two types of leadership under study. As a result, both the Moderated Regression Multiple analysis and structural equation model searched information on transformational and followership for empowerment having moderating effects. In the Moderated Regression Multiple analysis, results showed that empowerment for leadership in business in the regulation of followership role appeared not to be seen. However, using the structural equation modeling, moderating effects have been found.

The purpose of this study was to analyze the effects of food neophobia on food choice motives, such as health concern, weight control, ethical concern, and vegetable consumption. A total of 290 questionnaires were completed. Moderated regression analysis was used to measure the moderating effects of food neophobia. Results demonstrated Model 3 to be the best fit, compared to Model 1 and Model 2. In Model 3, the effects of health concern and food neophobia on vegetable consumption were statistically significant (p<0.01). However, the effects of weight control and ethical concern on vegetable consumption were not statistically significant (p>0.05). As expected, the combination of health concern and food neophobia had a significant effect on vegetable consumption (p<0.05). However, weight control and food neophobia, and ethical concern and food neophobia had no significant effects on vegetable consumption (p>0.05). Moreover, health concern related to vegetable consumption was statistically significant at all levels of food neophobia, except, when level of food neophobia was high (p<0.001). In developing and testing moderated regression models, which integrate relationship among food neophobia, health concern, weight control, ethical concern and vegetable consumption in the future, this study may provide a deeper understanding of the complex relationship among vegetable consumption behavior-related variables.

This study focuses on the instructor's role in student-centered learning and aims to test the effects and moderating role of instructor feedback on perceived loafing in team project-based learning. A conditional effect model including team efficacy, perceived loafing, instructor feedback, and team performance was proposed. Data were collected from students who registered for team project-based learning courses at a university in South Korea. A total of 420 cases were subjected to moderated mediation analysis. The results demonstrated that instructor feedback was negatively related to perceived loafing and moderated the relationship between team efficacy and perceived loafing. Furthermore, instructor feedback moderated the relationship between perceived loafing and team performance. In particular, even when perceived loafing was high, students who received frequent instructor feedback were found to significantly reduce the damage to team performance. Based on these findings, the importance of instructors' facilitation in team project-based learning is discussed.
