Purpose - The purpose of this study is to clarify the mediating effect of profitability and activity in the relationship between productivity and stock return, assuming that the productivity of the company will affect share prices with the parameters of profitability and activity. Design/methodology/approach - The study extracted productivity indicators, profitability indicators, activity indicators, and share price-related indicators from 1999 to 2018 of non-financial enterprises listed on the securities market, and then classified them into three factors: productivity (labor productivity LP, capital productivity CP), activity (TT), and profitability (net profit rate NI, operating profit ratio OI) through the factor analysis method, and analyzed the impact of each factor on the stock return through steps 1 to 3. Findings - The regression analysis shows that productivity has a significant positive effect on the stock return through the full mediating effect of profitability and activity. Research implications or Originality - In a situation where the relationship between productivity and profitability is not clear, this study is meaningful in that it has empirically analyzed that productivity has a positive effect on the stock return by mediating effects of profitability and activity.

This paper designed a mediating pathways model on how parental abuse and peer victimization lead to the development of suicidal ideation through the mediating variables of interpersonal needs and a hopelessness. The development is sure to help reduce adolescent suicidal ideation and, in turn, seek for distinct mediating methods to help teens with suicidal ideas. To validate the suggested model, this paper administered a questionnaire to 768 students in their 10th, 11th and 12th grades of high schools in Incheon, and then analyzed the structural equation model before confirming the research hypothesis by adopting the tools of SPSS 17.0 and AMOS 18.0. The result clearly demonstrates that parental abuse is one of the most influential factors in developing suicidal ideation. Peer victimization, however, had no direct bearing on suicide ideation, only indirectly affecting through the mediating variable of interpersonal needs. In addition, peer victimization had indirect effects on suicidal ideation through a sequential intervention of variables from interpersonal needs to a hopelessness. Based on the above results, this research has following implications: First, this paper analyzed the mediating pathways of youth suicidal ideation resulting from parental abuse and peer victimization. The result could possibly help find preventive measures and effective mediating approaches to save the lives of young people at risk of committing suicide. Secondly, this study proved that the interpersonal needs, a relatively new concept hardly introduced in previous studies, is a significant predictive factor for suicide ideation, serving as an intervening variable of developing suicidal ideation among young people who have suffered parental abuse and peer victimization.

The purpose of this study was to investigate the relationship between marriage migration females' acculturative stress and marital adjustment, especially the mediating and moderating effects of ego-resilience. The structural equation models were tested by setting marriage migration females' acculturative stress as a prediction variable, their marital adjustment as an outcome variable and their ego-resilience as mediator and moderator variables. The sample consisted of 172 marriage migration females from Busan. I analyzed the data using correlation analysis in order to discover the correlation coefficient of those variables among acculturative stress, ego-resilience and marital adjustment. I used the structural equation model (SEM) for investigating the relationship among acculturative stress, ego-resilience and marital adjustment and for investigating the mediating effects of ego-resilience. I also used multiple group analysis and two way ANOVA to investigate the moderating effects of ego-resilience. The results of structural equation modeling were as follows: first, it was proved that ego-resilience was exerted as a mediating variable, because acculturative stress appeared to affect marital adjustment in relation to ego-resilience. Therefore, marital adjustment was evident when ego-resilience was low. Second, it was proved that ego-resilience was exerted as a moderating variable, because those with low ego-resilience experienced high acculturative stress and low marital adjustment, and those with high ego-resilience experienced low acculturative stress and high marital adjustment. Such findings point out the importance of considering personal characteristics, like ego-resilience, in the relationship between acculturative stress and marital adjustment.

Purpose: The purpose of this study was to construct and test a hypothetical model about impact of parents' problem drinking on suicidal ideation of their children who are university students and the multiple mediating effects of childhood trauma, experiential avoidance, and depression based on stress-vulnerability model. Methods: A purposive sample of 400 university students was recruited from three universities in provincial areas and the data were collected between October and November 2016. The collected data were then analyzed using SPSS 20.0 and AMOS 20.0 programs. For data analysis, descriptive statistics, factor analysis, and structural equation modeling were performed. Multiple mediating effects analysis using phantom variable and bootstrapping were implemented to verify the mediating effect of the research model. Results: We found no significant direct effect on depression and suicidal ideation of parents' problem drinking, but multiple mediating effects of childhood trauma and experiential avoidance between parents' problem drinking and depression (B=.38, p=.001). The path from parents' problem drinking to suicidal ideation was significantly mediated by childhood trauma and depression (B=.02, p=.016) and by childhood trauma, experiential avoidance, and depression (B=.05, p=.011), but experiential avoidance did not have a significant direct effect on suicidal ideation (B=.02, p=.616). Conclusions: Based on the results of this study, it can be suggested that in order to decrease depression and prevent suicide of university students, considering of parents' problem drinking and childhood trauma, intervention methods that decreased chronic use of experiential avoidance and strengthen acceptance should be developed and made available to them.

Purpose: The aim of this research is to examine the moderating effects of self-esteem and resilience in the relationship between smartphone addiction and depression among middle school students. Methods: Data were collected from 324 middle school students in D City during the period of July 1st-17th, 2015. Multiple regression analysis, the Baron & Kenny's mediation verification, and Sobel test were conducted to measure the mediating effects of self-esteem and resilience on depression. Results: There were significant correlations among the variables; smartphone addiction, self-esteem, resilience, and depression. Self-esteem had a complete mediating effect (${\beta}=-.40$, p<.001) in the relationship between smartphone addiction and depression (Sobel test: Z=4.68, p<.001). Resilience had a partial mediating effect (${\beta}=-.15$, p<.001) in the relationship between smartphone addiction and depression (Sobel test: Z=2.40, p<.001). Conclusion: This study suggests to apply self-esteem and resilience in developing nursing intervention programs for adolescent depression caused by smartphone addiction.

This study examined the effects of teacher's self-efficacy on children's sociality through the mediating effects of job-satisfaction and the quality of teacher-child interaction. The participants in this study consisted of 27 teachers working at child care centers and 71 children(4-5 years old) in their charge in Seoul and Gyeonggi-do province, Korea. Data were analyzed by means of a Hayes's PROCESS(2012) program to identify the serial multiple mediating effects and the relationships which exist among the various factors. The present study found that teacher's self-efficacy had significant indirect effects on children's sociality through job-satisfaction and the quality of teacher-child interaction. These results suggest that a higher level of teacher's self-efficacy leads to greater job-satisfaction and better quality of teacher-child interaction and this in turn has an influence on children's sociality.
