Objective: The purpose of this study was to examine how job stress, coping style, and social support were associated with quality of life among child care teachers. Methods: The participants were comprised of 281 child care teachers in the metropolitan area of Seoul. Job stress, problem-focused coping style, social support, and quality of life were assessed by a teacher-reported questionnaire. Results: Correlation and regression analyses revealed that while job stress predicted lower quality of life, having problem-focused coping style and family support enhanced quality of life among child care teachers. Furthermore, results showed significant moderation effects of support from directors at child care centers on the relationship between job stress and quality of life among child care teachers. Conclusion/Implications: The findings suggest the important role of problem-focused coping styles and family support in enhancing quality of life. Moreover, support from directors at child care centers appeared to buffer the effects of job stress on quality of life among child care teachers. Results were discussed in terms of their implications for educational and counseling programs for child care teachers.

Purpose - Current study aimed at investigating customer experience types (gain vs. loss avoidance performance experience and hedonic vs. reliability imagery experience) and their influences on satisfaction and positive emotion as antecedents of customer engagement. It also explored moderation role of regulatory focus in the influence of each experience type on satisfaction and positive emotion. Research design, data, and methodology - 416 Vietnamese local tourists were selected to test hypotheses by structural equation model in AMOS 21.0. Results - First, customers actually achieving gain or avoiding loss are more satisfied. Second, customers with hedonic and reliability imagery experience feel more positive emotion. Third, both positive emotion and satisfaction have positive influences on customer engagement. Last, regulatory focus moderates the positive effects of either gain or loss avoidance performance experience on satisfaction and also moderates the positive effects of either hedonic or reliability imagery experience on positive emotion. Conclusions - Focusing on both cognitive satisfaction and affective emotion resulted from experience, this study could advance customer engagement theory. Managerially, brand managers should induce gain performance and hedonic imagery experience (loss avoidance performance and reliability imagery experience) from promotion (prevention)-focused customers to enhance their engagement.

Given the substantial industrial and economic contributions of university start-ups, a growing number of studies have adopted the ecosystem perspectives to systematically explain creating start-ups in universities. Despite the huge theoretical potential, few studies have analyzed the complex, complimentary interactions of the core components in the university entrepreneurship ecosystems (UEEs). Addressing the limitation, this research not only discusses the role of the core ecosystem components, such as patents, entrepreneurship education, and student entrepreneurship clubs, but also analyzes their discrete and complimentary effects on the productivity of UEEs. Based on a national survey of universities, this study shows that all the core components have a positive effect on the ecosystem productivity. More importantly, this study investigated the complimentary relationships among components and tested the moderation effects of both the entrepreneurship education and the student clubs on the relationship between the patents and the productivity of UEEs. The analysis results show that the student clubs intensify the patents' positive effect on the productivity of UEEs. The research results could provide the crucial policy insights for the successful design of UEEs.

Selecting graphite grades with superior irradiation characteristics is important task for designers of graphite moderation reactors. To provide reference information and data for graphite selection, the effects of irradiation on three fine-grained, iso-molded nuclear grade graphites, ETU-10, IG-110, and NBG-25, were compared based on irradiation-induced changes in volume, thermal conductivity, dynamic Young's modulus, and coefficient of thermal expansion. Data employed in this study were obtained from reported irradiation test results in the high flux isotope reactor (HFIR)(ORNL) (ETU-10, IG-110) and high flux reactor (HFR)(NRL) (IG-110, NBG-25). Comparisons were made based on the irradiation dose and irradiation temperature. Overall, the three grades showed similar irradiation-induced property change behaviors, which followed the historic data. More or less grade-sensitive behaviors were observed for the changes in volume and thermal conductivity, and, in contrast, grade-insensitive behaviors were observed for dynamic Young's modulus and coefficient of thermal expansion changes. The ETU-10 of the smallest grain size appeared to show a relatively smaller VC to IG-110 and NBG-25. Drastic decrease in the difference in thermal conductivity was observed for ETU-10 and IG-110 after irradiation. The similar irradiation-induced properties changing behaviors observed in this study especially in the DYM and CTE may be attributed to the assumed similar microstructures that evolved from the similar size coke particles and the same forming method.

Objective: The purpose of this study was to examine the effects of parent play support beliefs and children's playfulness on children's ego-resiliency. Methods: The participants for this study were 236 young children aged 3 to 5, their parents, and teachers in 19 daycare centers located in Seoul and Gyeonggi Province. Descriptive statistics, bivariate correlations, and hierarchical regression analysis were conducted. Results: The major findings were summarized as follows. First, overall, the level of parents' play support beliefs, children's playfulness and ego-resiliency tended to be high in the present sample. Second, mothers' play support beliefs and children's active participation in play were significantly and positively associated with children's ego-resiliency. Third, parents' play support beliefs had no moderation effect on the effects of children's playfulness on their ego-resiliency. Conclusion/Implications: The results of this study suggest that parents' play support beliefs and children's playfulness are effective in improving children's ego-resiliency.

The purpose of this study is to examine the effects of emotional arousals of guilt versus shame on health message compliance. The study also investigates the moderation impact of two individual factors that have not been studied much in health communications, including regulatory focus and self-construal. This study employs a 2 (guilt versus shame appeals/arousals) between-subjects experiment and a survey to test the conceptual model. The context of the study is binge drinking, and the survey respondents (n = 330) are male university students in Ho Chi Minh City, Vietnam. The results confirm the positive effects of guilt and shame arousals on health message compliance. In addition, the results show moderating effects of the two individual characteristics of regulatory focus and self-construal on the relationships between guilt/shame arousals and health message compliance. The findings of this study have not only theoretical implications but also practical implications in the field of health communications. The insights could help health marketers, policymakers, and health promotion agencies to effectively develop health communications campaigns with more appealing message content (guilt versus shame) and relevant media selection (regulatory focus and self-construal).

The effects of conflicted teacher-child relation on conflicted or passive peer interaction and a moderation effect of mothers' interpersonal relation satisfaction on the associations were assessed. Children from 2- to 6-year-olds (184 girls, 185 boys) mostly from middle socioeconomic-status urban community in Korea and their teachers and mothers participated. Conflicted teacher-child relation predicted conflicted peer interaction but not passive peer interaction. Children, whose relationship with teachers were conflicted, engaged in conflicted play with peers more often than children who were in less conflicted relationship with the teachers. Teachers who were in conflicted relationship with the children, perceived the children having conflicted interaction with peers more often, if mothers of the children were less satisfying in relationship with significant others, especially boys. Children, whose mothers are in less satisfying interpersonal relation with others, were more passive in peer interaction than children whose mothers are in more satisfying interpersonal relationship.

Sensitivity analysis by TSUNAMI clarifies the complex effects of key nuclides on the criticality probability quantitatively. As discussed above, the $K_{eff}$ of $UO_2$ fuel reaches the maximum value with 42w% concentration of intrusion water. The concentration of hydrogen affects the complexity of reaching criticality by its competition between the concentrations of $^{235}U$. Approximately if the weight percent of $H_2O$ in the mixture is less than 42%, the moderation effect of hydrogen surpasses its dilution effect on $^{235}U$. However, the importance of $^{235}U$ increases dramatically when the weight percent of water is bigger than 42%. In the sensitivity evaluation of $UO_2$ fuel employing TSUMAMI, there is a similar crosspoint of the sensitivity of $^{235}U$ and the sensitivity of $^1H$ where the criticality reaches summit. And the optimal water weight percent is determined to be 50%.

The purpose of this study is to examine the effects of nurses' emotional labor and the importance of leaders' emotional intelligence roles by verifying them with job satisfaction and organizational commitment for 396 nurses at 8 university hospitals in Seoul and Gyeonggi province. It was found that emotional labor had a negative relationship with job satisfaction and organizational commitment. And leaders' emotional intelligence has a significant positive relationship with job satisfaction and organizational commitment. However, leaders' emotional intelligence has no moderation effect on emotional labor and dependent variables. As this study shows that emotional labor and leader's emotional intelligence affect organizational effectiveness of hospital nurses, it would be important to not only manage members' emotional labor but to also develop the emotional intelligence of both leaders and the staff.
