The purpose of this study was to examine the mediating effects of experiential avoidance on the relationships between life stress, depression and smartphone addiction in nursing college students. This study was conducted using a descriptive survey design. Participants were 283 nursing college students attending freshmen and sophomore yearsat one university in Jeollanam-do. Data were collected from September 1 to 15, 2015 using self-report questionnaires. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, hierarchical regression and Sobel test with SPSS 21.0. There were significant positive correlations between life stress, depression, smartphone addiction and experiential avoidance. Experiential avoidance partially mediated the relationship between life stress and depression of nursing students. Additionally, experiential avoidance partially mediated the relationship between their life stress and smartphone addiction. The results show that experiential avoidance plays a key role in psychopathology and grows with depression and smartphone addiction. Based on the present findings, nursing interventions should be developed to decrease experiential avoidance, with additional consideration towards the relationship between life stress and experiential avoidance, in order to prevent depression and smartphone addiction among nursing college students.

After IRB approval, this study was performed by administering questionnaires to 180 university hospital patients between April and June, 2017. Collected data were analyzed with SPSS 22.0. The average score of nurse's communication, nursing needs, and nursing satisfaction were $3.88{\pm}0.52$, $3.96{\pm}0.55$, and $3.74{\pm}0.59$ out of 5, respectively. There were significant differences in educational and therapeutic needs versus satisfaction. As for nurse's communication and nursing satisfaction, there were significant differences by patient's room. There were positive correlations among nurse's communication and nursing needs (r=.286, p<.001) as well as nurse's communication and nursing satisfaction (r=.524, p<.001), In addition, there were positive correlations between nursing needs and satisfaction (r=.488, p<.001). Nursing communication had a partial mediating effect between nursing needs and satisfaction, which showed significance in Sobel's test (Z=2.450, p=.014). Therefore, it is suggested that a continuous program for strengthening communication of hospital nurses is needed.

This study has attempted to empirically analyze the mediating effects of small and medium venture firms' manufacturing capability and testing and inspection capability on the relation between their external information network heterogeneity and technology commercialization capability with a view to diversifying the research stream on the influential factors to small and medium firms' technology commercialization capability. By performing the ordinary least squares regression analysis, the Sobel test, and the Baron and Kenny test based on the 683 data of South Korean small and medium venture firms with the IBM SPSS version 23, this study provides the three empirical findings to be useful for future studies on the roles of small and medium venture firms' the manufacturing capability and testing and inspection capability. First, small and medium venture firms' manufacturing capability partially mediates the positive effect of their external information network heterogeneity on their technology commercialization capability. Second, their testing and inspection capability partially mediates this positive effect. Third, their manufacturing capability and testing and inspection capability jointly and partially mediates this positive effect.

This study examined the effects of adolescents' stress coping behavior on gambling addiction using the irrational belief of gambling as a mediating variable. For this, a questionnaire survey was conducted on 377 high school students in Jeju. Data processing analysis of the research was verified by Baron & Kenny's regression analysis in 4 phases and a Sobel Test was done to verify the significance level on the mediation effect. The study results can be summarized as follows. First, while problem-focused coping had a negative (-) correlation with gambling addiction, emotion-focused coping had a positive (+) correlation with gambling addiction. Second, the irrational belief of gambling had no mediating effects on the relationship between problem-focused coping and gambling addiction. Third, the irrational belief of gambling had a full mediating effect on the relationship between emotion-focused coping and gambling addiction. In conclusion, emotion-focused coping under stress situations would enhance the gambling behavior by increasing the irrational belief of gambling. Therefore, it is necessary to develop programs to improve the adolescents' stress coping skills and rationally correct their irrational belief of gambling, which will be helpful in preventing adolescents' gambling addiction. The limitations of this study are discussed together with suggestions for future research.
