This study attempts to provide a comprehensive framework for listening strategy use among university students in Korea in relation to TOEIC listening scores. In particular, this study tests whether motivation, based on the self-determination theory, mediates listening strategy use on listening comprehension (LC) process and whether reading comprehension ability moderates the use of listening strategy in LC achievement. One hundred seventy six freshmen students participated in the study during their first semester required English course. Self-report questionnaires were used to assess students' motivation and LC strategy use. The responses were statistically analyzed via the moderator and mediator model. The results indicate that internalized motivation mediates the use of listening strategy in LC achievement; however, reading comprehension skill doesn't affect students' use of listening strategies in relation to listening skill achievement. In other words, students who have internalized motivation were able to utilize listening strategies effectively in terms of achievement of the TOEIC listening skills. The findings of the current study offer in-depth understanding of the relationship among use of LC strategies, intrinsic motivation, and listening skill achievement shared by the mediator and moderator models.

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. Limitations of the study and suggestions for the future studies were discussed.

The purpose of the present study was to test the mediating effect of children's creativity on the relationship among the openness to experience(OE) trait, maternal parenting behaviors, and their subjective well-being. 248 children attending elementary schools in the rural areas of Korea and their mothers were recruited. Results indicated that creativity partially mediated the relations between children's OE and their subjective well-being. However, creativity did not mediate the relations between maternal parenting behaviors and children's subjective well-being. Results of the present study suggest that the OE may influence children's adjustment through creativity. It is also implied that there may be no optimal parenting style which unconditionally promotes children's creativity.

The purpose of this study is to investigate factors influencing educational performance and mediating effects of learning presence in the university flipped learning classroom. For achieving this purpose, self-regulation, learning presence, and collaborative preference were selected as learner variables, and perceived academic achievement and learning engagement were selected as variables for educational performance. To investigate causal relationships among the variables, 39 university students who took 16 week course flipped-learning class participated self-reported survey. Collected data were analyzed by multiple regression and mediation analyses. The results were as follows: first, learning presence and self-regulation affected learning engagement, and moreover, the learning presence mediated between self-regulation and learning engagement. Second, only learning presence affected perceived academic achievement. Therefore, various strategies for effective flipped learning should be considered, and well-designed classroom activities that can promote learners self-regulation, learning presence, and learning engagement are needed to successful flipped learning.

The current paper not only investigates the intermediating process of the association between servant leadership and safety behavior, but also tries to find a factor which enhances the positive influence of servant leadership. To do that, this study tried to identify the mediating effect of employee's psychological safety between servant leadership and safety behavior, as well as the moderating influence of perspective taking ability in the servant leadership-psychological safety link. By utilizing 3 wave survey data from 235 employees in Korean companies with conducting structural equation modeling(SEM), this paper found that servant leadership had a positive influence on safety behavior through mediating effect of employee's psychological safety. In addition, the perspective taking ability positively moderated the positive impact of servant leadership on psychological safety.

This study aims to offer a wide range of practical implications for Smartphone addiction prevention by verifying the effect of mind health as a factor that is influenced by Smartphone addiction, and testing the relationships between Smartphone addiction and mind health with school life adaptation as a mediation effect. For this research, a survey was conducted of 250 elementary school students who use Smartphones. The relationships between Smartphone addiction, mind health and school life adaptation were set as the structural equation model, and they were verified by the mediation effect of school life adaptation. The results showed that school life adaptation turned out to be an entirely mediating variable on the relationship between mind health and Smartphone addiction. The statistical significance of the effect on school life adaptation was verified by the Sobel test. The mediation effect resulted in mind health reducing the occurrence of negative emotion of school life adaptation, and also reinforced decreased Smartphone use.

This paper tried to determine whether emotional dysregulation would function as a mediating variable when social exclusion affects SNS addiction tendencies. For this purpose, a survey was conducted targeting students enrolled in a university located in the central region. Responses from 298 people were analyzed. The analysis results show that social exclusion completely mediates emotional dysregulation and influences SNS addiction tendencies. Meanwhile, we set the two sub-dimensions of social exclusion as independent variables to determine whether it influences SNS addiction tendency through emotion regulation. It was found that the experience of being ignored influenced the tendency to addict to SNS by partially mediating the experience of emotion regulation, while the experience of rejection was found to affect the tendency to addict to SNS by fully mediating the experience of emotion regulation. These analysis results show that when establishing social exclusion as an influential factor in SNS addiction tendency, it is meaningful not only to set it as an overall factor but also to approach it by dividing it into individual factors.
