Objective: This study assessed whether both physical disability and perceived dependence relate to depression or whether perceived dependence in personal care activities, household activities, community mobility and recreational activities is an intermediate step in the relationship between physical disability and depressive symptoms. Methods: Data come from a cross-sectional survey of 209 women, aged 55 or older, with osteoarthritis (OA). Mediation analyses occurred in four step and included logistic regression analyses as outlined by Baron & Kenny. Results: The results from step 1 showed that greater difficulty with each domain of physical disabilities was significantly related to greater perceived dependence. In step 2, greater perceived dependence was significantly associated with greater depressive symptoms in all domains. Step 3 analyses showed that greater physical disabilities in each domain were significantly associated with depression. The final step testing mediation indicated that personal care activities, household activities and community mobility were fully mediated by perceived dependence. That was, once dependence was taken into account, the relationship between physical disabilities and depression was no longer significant. Partial mediation was found for dependence and recreational activity limitations. Conclusion: It is important to take into account the experience of perceived dependence as a mediator in understanding the relationship between disability and depression in the domains of personal care, household, and community mobility. To conclude, these findings point to the importance of taking into account an individual's reaction to their disability rather than just focusing on the severity of disability.

This study examines the relationships among ego resilience, social support, and psychological well-being of adolescents. In addition, we verify the mediation effect of social support on the relationship between ego resilience and psychological well-being so as to find ways to improve the psychological well-being of adolescents. For this study, I conducted a survey at middle schools in Seoul and Incheon and collected 289 answered questionnaires. For analyses of the survey results, frequency analysis, reliability analysis, correlation analysis, and hierarchical regression analysis were carried out using SPSS 23.0. The results confirmed significant correlations among ego resilience, social support, and psychological well-being of adolescents. Furthermore, social support was found to have a partial mediation effect on the relationship between ego resilience and psychological well-being of adolescents. For improving the psychological well-being of adolescents based on the results of this study, an in-depth counseling program that can strengthen ego resilience in adolescents should be developed and actively used in the education field. Furthermore, various efforts should be made to improve the social support of adolescents, such as the development of a communication program to help students. Specifically, this program should aim to assist students connect with teachers and seniors by strengthening social support from friends and improving the functions of family to provide social and psychological supports.
This study aimed to identify the causes of adult cyberbullying, an issue which arouses little academic interest despite its seriousness and its harmful consequences, in order to provide basic data for the formulation of reasonable measures for preventing and reducing adult cyberbullying. To that end, the author of the study analyzed the results of the government-led Cyber Violence Survey conducted in 2019. First, the online survey panel owned by the research company selected a sample of 1,500 adult men and women in their 20s to 50s in proportion to reflect the composition of the local population. The survey was conducted online, with male subjects and female subjects accounting for 51.5% and 48.7% of the respondents, respectively. The result of the analysis shows that the respondents' attitude towards cyberbullying was fully mediaed according to such factors as gender, age, family relations, relationship with colleagues, Internet usage time, and contact with illegal content. In addition, partial mediation was observed with regard to online delinquency colleague numbers and cyberbullying victimization. As a result, the respondents' attitude towards cyberbullying was found to be the most important factor affecting adult cyberbullying. Based on these results, this study suggests that the formation of a non-conservative attitude towards cyberbullying should be considered to be more important than any other factors when preparing programs aimed at preventing cyberbullying.
This study empirically analyzed the factors affecting the intention to utilize manufacturing AI in SM-sized manufacturers by applying the TOE framework. Independent variables that are expected to influence were applied, focusing on TOE factors and managerial characteristics that reflect the characteristics of SME manufacturers. In addition, the mediating effect of technology trust and the moderating effect of factory location were analyzed. The results are as follows. First, the relationship between the independent variables and the dependent variable was tested, and the direct effects of the independent variables(complexity, organizational innovation, IT ability, competitive pressure, partner support, and managerial innovation) on the dependent variable were all statistically significant, except for compatibility. Second, the mediation effect of technology trustness was verified to have a full mediation effect between compatibility and utilization intention, and a partial mediation effect between managerial innovation and utilization intention. Third, among the seven independent variables, the moderating effect of factory location(metropolitan and non-metro) between the three independent variables of IT ability, competitive pressure, and partner support and the utilization intention was found to be significant. To increase the intention to utilize manufacturing AI for SM-sized manufacturers, it is recommended that more diverse and broader studies are needed, not only the factors identified in this study, but also the understanding and awareness of manufacturing AI.
The purpose of this study includes: the relationships between corporate entrepreneurship(innovation, proactiveness, risk-taking) and firm performance(non-financial performance, financial performance) and the mediating effect of the self-efficacy on the relationship between corporate entrepreneurship and firm performance. In order to verify the relationships and mediating effect, data were collected from 368 individuals in employees working in small and medium-sized firms at Gyeongnam region to test theoretical model and its hypotheses. All data collected from the survey were analyzed using with SPSS 18.0. This study reports findings as follows: first, the relationship between the corporate entrepreneurship(except innovation) and the employee's self-efficacy is positively related. Second, there was also a positive correlation between the employee's self-efficacy and firm performance. Third, the relationship between the corporate entrepreneurship and the non-financial performance is positively related. The relationship between the corporate entrepreneurship(except innovation) and the financial performance is positively related. Finally, the employee's self-efficacy played as a partial mediator on the relationship between risk-taking and firm performance. The employee's self-efficacy played as a fully mediator on the relationship between proactiveness and non-financial performance. The employee's self-efficacy played as a partial mediator on the relationship between proactiveness and financial performance. However, there was no empirical evidence for the mediating effect of employee's self-efficacy on the relationship innovation and firm performance. Based on these findings, the implications and the limitations of the study were presented including some directions for future studies.
This study examines the mediating effects of learned helplessness and procrastination in the relationship between covert narcissim and selfie addiction proneness among women. The study subjects were 286 women with a mean age of 23.78(SD=4.34) years. The results of the study are as follows. First, there were significantly positive correlations between covert narcissism, self-objectification, self-presentational motivation, and selfie addiction proneness. Second, covert narcissism, self-objectification, self-presentational motivation were significant predictors for selfie addiction proneness and they accounted 25.7% for variance of selfie addiction proneness. Especially, self-presentational motivation accounted for selfie addiction proneness the most. Third, mediating effect analysis showed self-objectification had partial mediation effect on the relation between covert narcissism and selfie addiction proneness and self-presentational motivation had a partial mediating effect on the relation between covert narcissism and selfie addiction proneness. It is significant for this study to define the concept of selfie addiction proneness and understand psychological variables which significantly account for it.
