This study takes a holistic approach to understand the diffusion of IPTV services by combining the adoption-diffusion model and the use-diffusion model of innovation. IPTV service, a leading digital converged application coupling media content with telecommunications, has been recently launched commercially in Korea. We created a structural model of adoption-diffusion, using the perceived easeof-use and usefulness of TAM(Technology Acceptance Model) as mediating variables, and a structural model of use-diffusion, with the rate of use and the variety of use as mediating variables. To empirically analyze these models, non-users of IPTV were surveyed using the adoption-diffusion model to identify factors influencing their intention to subscribe to the service. Meanwhile, users of IPTV were surveyed using the use-diffusion model to determine the factors that influence their satisfaction with the service and their intention to re-use it. Under the adoption-diffusion model, we found that trialability, household innovativeness and perceived risk were the determinants of user satisfaction with IPTV, and perceived ease-of-use, the mediating factors. Under the use-diffusion model, complementarity and communication were shown to be the determinants of users' satisfaction with IPTV, and variety of use, the mediating factor. We also found that consumers' intention to re-use IPTV was strongly influenced by its relative advantage and perceived risk.

This study aims to empirically verify the impacts of career learning on employability and the mediating effect of job expertise in a public corporation. For the empirical analysis, I surveyed 958 employees(valid respondents) working in a public corporation. And the structural equation modeling(SEM) was used to statistically analize and test the research hypotheses. The independent variable is 'career learning', the dependent variable is 'employability' and the mediating variable is 'job expertise'. The results are as follows. The empirical analysis shows that the positive effects of 'career learning ${\rightarrow}$ job expertise', 'job expertise ${\rightarrow}$ employability' and 'career learning ${\rightarrow}$ employability' are all verified. And the mediating effect of job expertise between career learning and employability is also partially verified. So, all the proposed hypotheses are accepted. From this result, I can clearly suggest that the employees can be growing to professionals with high employability when they retire if they are voluntarily and self-motivated to set up their career plan and to enhance their job expertise. In this context, it is expected that the company should support the employees to continue to strengthen their own expertise in their job place through their mid-long term career learning plan.

Purpose: The purpose of this study was to determine the impacts of vocational calling, emotional intelligence, and major commitment on nursing college students' happiness. This study also was conducted to explore major commitment's mediating effect on the relationship between vocational calling, emotional intelligence, and major commitment among nursing college students. Methods: Participants were 346 nursing college students. Data were collected in November, 2017 with self-report questionnaires and were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficients, and regression analysis with IBM SPSS 19.0. Results: The regression model explained 33.0% of variance in nursing college students' happiness (F=41.44, p<.001). Significant factors were emotional intelligence (${\beta}=.30$, p<.001), grade (${\beta}=.20$, p<.001), major commitment (${\beta}=.18$, p=.002), and vocational calling (${\beta}=.11$, p=.035). Moreover, major commitment showed partial mediating effects on vocational calling and happiness. Major commitment also showed partial mediating effects on emotional intelligence and happiness. Conclusion: The results suggest that nursing college students' happiness can be increased through strategies aimed at increasing vocational calling, emotional intelligence, and major commitment.

Purpose: The purpose of this study was to identify the mediating effect of compassionate competence on the relationship between nurses' spirituality and attitude toward care of dying patients. Methods: A cross-sectional correlational research design was conducted. The total subjects were 172 nurses at one general hospital in Gangwon-do. Data were collected using self-report questionnaires and analyzed using t-test, one-way ANOVA, Scheffe's test, Pearson's correlation coefficients, and multiple regression analysis. Results: Compassionate competence showed the mediating effect (${\beta}=.19$, p=.025) on the relationship between nurses' vertical spirituality and attitudes toward care of dying patients. However, no mediating effect of compassionate competence on the relationship between nurses' horizontal spirituality and attitudes toward care of dying patients was found. Conclusions: Based on the findings of this study, development of training programs with a focus on spirituality and compassionate competence was highly recommended to improve and maintain nurses' positive attitudes toward caring of the dying patients.

Purpose : This study aimed to identify the moderating and mediating effects of resilience on the relationship between role conflict and job satisfaction among nurses working in a comprehensive nursing care service ward. Methods : Participants were 130 comprehensive nursing care service ward nurses from four hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and hierarchical multiple regression analysis, using SPSS 25.0. The mediating effect of resilience on the relationship between role conflict and job satisfaction was analyzed using multiple regression analysis according to Baron and Kenny's procedure. Results : Statistically significant negative correlations were found between role conflict and resilience (r=-.25, p<.007) and between role conflict and job satisfaction (r=-.38, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.54, p<.001). A partial mediating effect of resilience was found between role conflict and job satisfaction (Z=-2.53, p=.012) but no moderating effect was found. Conclusion : To improve the job satisfaction of comprehensive nursing care service ward nurses, interventions for alleviating role conflict and improving resilience as well as evaluations of the two variables are necessary.

Objectives: This study aimed to investigate the effects of verbal violence experience on stress and positive psychological capital as well as the mediating effects of positive psychological capital. Methods: A survey was conducted with dental hygienists working at university hospitals, general hospitals, and dental hospitals and clinics in Busan, Gyeongnam, and Ulsan areas.Of the 230 questionnaires distributed, 206 were used in the analysis after excluding 24 completed questionnaires that had errors or missing answers. Results: As a result of identifying the relationships between verbal violence damage, positive psychological capital, and stress, verbal violence damage was negatively correlated with positive psychological capital (r=-0.28, p<0.001) and positively correlated with stress (r=0.40, p<0.001). Positive psychological capital had a negative correlation with stress (r=-0.25, p<0.001). As a result of verifying the mediating effects of positive psychological capital on the relationship between verbal violence damage and stress among dental hygienists, it was found that verbal violence had a significant effect on stress and positive psychological capital in the first and second stages. In the third stage, the effect of positive psychological capital on stress was significant, showing that there was a mediating effect. Conclusions: Therefore, sound work environments should aim to reduce verbal violence while increasing support systems to reduce negative emotional and psychological states.

Purpose: The purpose of this study was to examine the mediating effect of self-perception on the relationship between body image and depressive symptoms in middle school adolescents. Methods: This study performed a pathway analysis with a sample of 284 adolescents recruited from three middle schools. Self-reported questionnaires consisted of items regarding body image, self-perception, and depressive symptoms. Results: Body image, self-perception, and depressive symptoms showed a significant correlation. Self-perception was directly affected by body image and depressive symptoms were not affected by body image. The mediating effect of self-perception on body image's impact on depressive symptoms was confirmed. Self-perception had a significant indirect effect on depressive symptoms, which means that self-perception has a full mediating effect on body image's impact on depressive symptoms. Conclusion: The effect of body image on depressive symptoms was fully mediated by self-perception in early adolescents. It suggests that self-perception needs to be considered when providing nursing interventions for adolescents.
