The aim of the current study is to examine the effects of mothers' home management ability on school-aged children's time and life management skills through the mediation effect of children's self-regulation. Study subjects were 317 5- and 6-grade children at elementary schools located in Seoul and Gyeonggi area and their 317 mothers. The findings were as follows. First, in the SEM model of predicting children's time management skill, greater mothers' home management ability significantly predicted better time management skills among their children. Second, mothers' home management ability also indirectly affected children's time management skill through its significant effects on children's self-regulation. The test yielded a significantly mediation effect of self-regulation. Children's self-regualtion was strongly related to time management skills. Third, in the SEM model predicting children's life management skills, maternal ability of home management again directly predicted greater life management skills of their children. However, mediation of self-regulation was not statistically significant. The findings suggested the important role of mothers' home management ability in instilling and modeling self-regulation and self-management skills of school-aged children.

Objectives Internet gaming disorder (IGD) is associated with attention deficit/hyperactivity disorder (ADHD) or depression etc. We tried to examine the mediating effects of depression in the relationship between ADHD and IGD. Methods This study was conducted on 2000 people who participated in on-line survey among 14-39 year-old men and women in 2017. And we clarified the relationship among IGD, ADHD, and depression and tested the mediation model. The mean and standard deviation of the main variables were calculated and correlation analysis was performed to confirm the relationship among the main variables. In order to test the mediating effect of depression on the relationship between ADHD and IGD, the structural equation model was implemented using AMOS 21 (IBM). Results There were significant correlations among the variables; IGD, ADHD and depression. Depression had a mediating effect 0.23 (95% confidence interval : 0.17-0.28) in the relationship between IGD and ADHD. Conclusions This study showed that depression can mediate ADHD and IGD. Therefore, the evaluation and management of depression and ADHD should be included in the diagnosis and treatment of IGD.

This tutorial introduces procedures and methods for performing structural equation modeling using R. To do this, we present advanced analysis methods based on structural equation model such as mediation effect analysis, moderation effect analysis, moderated mediation effect analysis, and multiple-group analysis with R program code using R lavaan package that supports structural equation modeling. R is flexible and scalable, unlike traditional commercial statistical packages. Therefore, new analytical techniques are likely to be implemented ahead of any other statistical package. From this point of view, R will be a very appropriate choice for applying new analytical techniques or advanced techniques that researchers need. Considering that various studies in the social sciences are applying structural equations modeling techniques and increasing interest in open source R, this tutorial is expected to be useful for researchers who are looking for alternatives to existing commercial statistical packages.

This paper deals with the effects of teamwork competence on problem solving ability through the mediating effect of creative personality for the engineering students. For this purpose, a regression-based statistical mediation analysis has been performed for a simple mediation model in which teamwork competence and problem solving ability were treated as independent and dependent variables respectively, and creative personality was included as a mediation variable. The analysis results showed that the teamwork competence has direct effect on the problem solving ability as well as indirect effect through the creative personality. This result implies that the problem solving ability can be improved directly by improving the teamwork competence, and moreover, it can be further improved indirectly or through the mediation effect by improving the creative personality. Thus, in order to develop excellent problem solving ability, it is necessary to form team members in a balanced way between teamwork competence and creative personality in the team-based learning.

Purpose: The purpose of this study was to investigate the relationship between employee authenticity and customer loyalty. This study also examined whether rapport positively mediated the above relationship. In addition this study address the moderating role of customer emotional intelligence in the relationship between employee authenticity and rapport. By developing moderated a mediation model, we addressed indirect conditional effect of customer emotional intelligence on the relationship between employee authenticity and customer loyalty via rapport. Methods: The survey data was collected by customers who used various services in Korea. The main hypotheses were tested using a cross-sectional design, with questionnaires administered to 292 customers. Results: The result of empirical analysis has shown that employee authenticity was significantly positively related to customer loyalty. We have also found that rapport positively mediated the relationship between employee authenticity and customer loyalty. While there was a significant moderating effect of customer emotional intelligence on the relationship between employee authenticity and rapport, the moderated mediating role of customer emotional intelligence was found. Conclusion: The results provide useful theoretical and practical implications to the organizations and managers who want to improve customer loyalty. Future research directions with the limitation of the study were discussed.

I. Preface It is widely understood that the 21st century, with the development of information technology(IT) and the spread of networks, will be called a digital economy where information-driven business will be norm rather than the smokestack economy of the past. And the drastically changed world market is expected to generate even more commercial transactions across the world creating large numbers of legal disputes. Therefore, each country will attempt to develop ADR(Alternative Dispute Resolution) as an alternative to judicial proceedings in order to cope with not only the ever-increasing international commercial claims but also domestic legal disputes. Taking this reality into account, this study begins with an exploration of mediation procedure as a way of helping the court faced with its overwhelming numbers of lawsuits. And also this study makes a theoretical comparison between ADR and mediation procedure, analyzing critical factors affecting the mediation agreement. Furthermore, it is designed to find ways for disputing parties to make better use of mediation and ensure fairness to the parties involved. It tries to enhance mediators' understanding of critical factors influencing the mediation agreement and their ability to handle commercial disputes in a more efficient way. To make an empirical analysis of these factors, bibliographic research and questionnaire were used. This analysis will fill the gap between the theory and reality, and make possible the structured research on the factors. Therefore, this study sets the model by which we can evaluate how the three critical factors (parties' inclination, mediators' characteristics, institutional features) affect the parties reaching a mediation agreement. Based on this analysis, a theoretical hypothesis was built and a questionnaire was made and distributed. During the course of this work, SPSSWIN 10.0 program was applied.

This study examined the moderated mediation effect, consisting of the moderation effect of alexithymia and the mediation effect of hostility in the relationship between emotional labor and depression of casino dealers. A total of 160 casino dealers (56 males, 94 females) working in a foreigner exclusive casino in Seoul responded to a survey on emotional labor, alexithymia, hostility and depression. SPSS 22.0 Macro was used to verify the moderated mediation effect. First, the level of depression amplified as the emotional labor of casino dealers increased. Hostility had a significant partial-mediation effect on the relationship between emotional labor and depression. Second, the moderation effect of alexithymia was significant, indicating that the interaction effect of emotional labor and alexithymia as well as hostility and alexithymia predicted depression. Third, the moderated mediation effect of alexithymia was significant. Alexithymia moderated the influence of emotional labor on depression, which was mediated through hostility. Implications on how to assist casino dealers on emotional labor were discussed.

This study showed that the association between solidarity and conflict is mediated by the communication of grandmothers and an adult child at the dyadic level. The common fate model (CFM) was designed to model mediation effects at the level of dyads. Participants consisted of 297 grandmother dyads and their adult child who were rearing preschool-aged grandchildren in Seoul and Gyeonggi-do. For analysis at the dyadic level, grandmothers and adults responded to the same questionnaire on the same variables. SPSS 23.0 performed descriptive statistical analysis and correlation analysis. The structural equation model (SEM) was estimated with AMOS 23.0. We tested the mediation model using the maximum likelihood method. Model fit index used the chi-square statistic, the incremental fit index (IFI), the comparative fit index (CFI), the root mean square error of approximation (RMSEA). The statistical significance of the indirect effect was examined using a bootstrapping procedure. The results are as follows. First, in the CFM, the direct effect between solidarity and conflict was significant. Therefore, the higher the solidarity, the lower conflict of grandmothers and an adult child. Second, the association between solidarity and conflict is mediated by communication at the dyadic level. Based on the results of this study, we discussed ways to strengthen the capacity of co-parenting between grandmothers and an adult child.
