This study investigates the effects of different types of digital informatization (i.e. access, skill, utilization) on life satisfaction. The mediation effects of the outcome of digital device use between digital informatization and life satisfaction are also tested. The '2020 Survey on the Digital Divide' conducted by the National Information Society Agency was referenced for empirical analysis. The findings show that in general, digital informatization contributes to improving life satisfaction. In addition, the outcome of digital device use mediates the positive relationship between digital informatization and life satisfaction. However, the magnitudes of the effects of digital informatization and mediation effects differed according to the types of digital informatization. This study supports the necessity and justification for a digital informatization policy and provides valuable information that helps establish and promote digital informatization policies. In addition, this study helps to understand the determinants of the third-level digital divide information by examining the relationship between digital informatization and the outcome of digital device use.

The previous studies of online entrepreneurship education were conducted only on the effect of education on actual entrepreneurship, but did not analyze the effectiveness of education. In this study, beyond of limits of previous studies, we investigated the effect of social presence on learning expectancy and educational satisfaction. In addition, we examined the influence of learning expectation on the relationship between social presence and educational satisfaction. For the research hypothesis test, we conducted a questionnaires survey on 189 graduate students who taken online courses related to entrepreneurship, hypothesis and questionnaires were made based on the research hypotheses precedent theories. And educational satisfaction was divided into operational satisfaction and content satisfaction. As a results of the analysis using the structural equation model, social presence has a positive effects on learning expectancy. Next, the learning expectancy has a positive effects on the operational satisfaction and the content satisfaction. Finally, when social presence affects operational satisfaction, learning expectation has a complete mediation effects and content satisfaction has a partial mediation effects. The implications of the results of this study were as follows. There was a need for a way to interacted with learners when conducted online entrepreneurial education. When increased the satisfaction level of the learning operation, it is necessary to reduced the burden of learners and raised the expectancy.

Purpose - The present study examines the effect of service employees' experienced customer incivility through their emotional exhaustion. We identified service employees' emotion regulation ability as a boundary condition (i.e., moderating variable) that decreased the positive relationship between service employees' experienced customer incivility and their emotional exhaustion. Furthermore, we also investigated the negative relationship between service employees' experienced customer incivility and their service performance via emotional exhaustion. Research design, data, and methodology - Drawing on AET (affective event theory) and COR (conservation of resources) theory, we developed three research hypotheses (i.e., mediation, moderation, and moderated mediation). Online panel survey data from 552 frontline employees at several service organizations (e.g., department stores, retail stores, hotels, restaurants, airlines, banking, insurance company, and etc) in South Korea were examined. To assess two types of validity (i.e., convergent and discriminant validity) and reliability of measurement model, we employed the CFA (confirmatory factor analysis) using M-plus 8.2 software. Internal consistency also was tested by Cronbach' α. In addition, we employed the SPSS PROCESS MACRO 2.16, which was recommended by Hayes (2013, 2015), to estimate mediation, moderation, and moderated mediation effects. Results - As predicted, the negative relationship between service employees' experienced customer incivility and their service performance was mediated by emotional exhaustion. Furthermore, service employees' emotion regulation ability also played a significant moderating role of the relationship between service employees' experienced customer incivility and emotional exhaustion, such that this relationship was less pronounced when service employees had a high level of their emotion regulation ability than when thir emotion regulation ability was low. Service employees' emotion regulation ability further moderated this mediation effect of service employees' experienced customer incivility on service performance through emotional exhaustion. These findings have theoretical implications for employees' experienced customer incivility and emotion regulation ability research and provide managerial implications for practitioners. Conclusions - This study empirically elaborated the previous model of service employees' experienced customer incivility and personal resource (e.g., emotion regulation ability) literature by presenting the findings that service employees' experienced customer incivility influences their service performance via emotional exhaustion and that emotion regulation ability effectively reduces this negative effect.

The study explored the association between narcissism and sexual dating violence, and how ambivalent sexism affects the relation. Additionally, this study investigated if there exists gender difference in the relations between factors of narcissism and sexual dating violence, and the mediating effects of ambivalent sexism. Based on 200 participants(100 males and 100 females), the mediation effect of ambivalent sexism on the relation between narcissism and sexual dating violence was examined. For male participants, the mediation effect of hostile sexism on the relation between narcissism and sexual dating violence was significant, whereas for female participants the mediation effect of benevolent sexism on the relation between narcissism and sexual dating violence was significant. Different patterns were evident regarding the associations between factors of narcissism and sexual dating violence. For males, the more with exhibitionism and entitlement, the more with hostile sexism, and the more with sexual dating violence. For females, the more with exhibitionism, entitlement, and self-sufficiency, the more with benevolent sexism, and the more with sexual dating violence. The study revealed that the mediation effect of ambivalent sexism between narcissism and sexual dating violence differed by gender and by factors of narcissism. Finally, preventions measures for sexual dating violence were discussed.

The main aim of the current study is to examine the effects of mothers' parental beliefs and mother-child attachment on school-aged children's time management and life management skills through the mediation effects of children's self-regulation. Study participants included a total of 317 fifth- and sixth-grade children at elementary schools located in Seoul and Gyeong-gi area, and their 317 mothers. Children and mothers completed questionnaires and Structural Equation Modeling was adapted as the main analysis technique. The findings were the following: First, mothers' parental beliefs that emphasize the child's independence were significantly related to greater self-regulation ability in children, indicated by cognitive, motivational, and behavior regulation. Second, better quality of mother-child attachment perceived by children was also found to predict greater self-regulation in children. Third, children's self-regulation was strongly related to time and life management skills. When the child is better at self control, the child showed greater management skills, both in time and everyday life. Finally, as hypnotized, the test yielded a significant mediation effect of self-regulation in the association from mothers' parental beliefs and mother-child attachment to children's time and life management skills. The findings suggested the important role of parental beliefs about child rearing and attachment between mother and child in developing self-regulation and management skills of school-aged children.

This study intended to explore fundamental causes affecting consumers' response actions from psychological factors in the situation of sellout occurring during shopping in online fashion stores. In addition, this study devised a virtual online shop in order to measure consumers' cognitive and emotional psychological responses they experienced when goods were sold out. The subjects involved women in 20s~30s, major customers of online shopping, and the subjects were randomly allocated to one of eight questionnaire forms (2(stockout size: high vs low)${\times}2$(product assortment similarity: similar vs. dissimilar)${\times}2$(restocking cue: included vs excluded)). The number of final data used for the analysis was 336 and through SPSS 21.0 program, two-way ANOVA and bootstrap were utilized. The analysis result was that consumers' psychological responses (emotions, psychological reactance) of online shops differed by means of varying stockout situations. The stockout size had positive effect on psychological reactance and negative emotions. On the other hand, there was no difference in positive emotions (arousal) according to stockout size. In stockout situation of online fashion store, the moderating effect of product assortment similarity and restocking cues were verified. According to the analysis result, interaction effects between stockout size and restocking cues, product stockout size and product assortment for psychological reactance were significant. Lastly, the mediation effect of psychological reactance and emotion between stockout size and behavioral response was tested. As a result, the moderated mediation effects of psychological reactance for substitute were significant when product assortment was dissimilar and restocking cue was exclude.
