Purpose: This study aimed to examine the levels of perceived self-management support, self-efficacy for self-management, and health-related quality of life (HRQoL) in cancer survivors, and to identify the mediating effect of self-efficacy in the relationship between perceived self-management support and HRQoL. Methods: This study used a descriptive correlational design. Two hundred and four cancer survivors who had completed treatment participated in the study. Measurements included the Patient Assessment of Chronic Illness Care Scale, the Korean version of the Cancer Survivors' Self-Efficacy Scale, and the Medical Outcomes Study Short Form-36. Data were analyzed using descriptive statistics, Pearson's correlation coefficient analysis, and multiple regression analysis using Baron and Kenny's method for mediation. Results: The mean score for perceived self-management support was 3.35 out of 5 points, self-efficacy was 7.26 out of 10 points, and HRQoL was 65.90 out of 100 points. Perceived self-management support was significantly positively correlated with self-efficacy (r=.29, p<.001) and HRQoL (r=.27, p<.001). Self-efficacy was also significantly correlated with HRQoL (r=.59, p<.001). Furthermore, self-efficacy (${\beta}=.55$, p<.001) had a complete mediating effect on the relationship between perceived self-management support and HRQoL (Z=3.88, p<.001). Conclusion: The impact of perceived self-management support on HRQoL in cancer survivors was mediated by self-efficacy for self-management. This suggests that strategies for enhancing self-efficacy in cancer survivors should be considered when developing self-management interventions for improving their HRQoL.

Purpose - This study aims to verify the direct causal relationship between cost competitiveness and global network competitiveness, which are the tangible service quality factors determined by the shipping company, which in turn affect the shipper's customer satisfaction. Additionally, we empirically investigate the intangible, related service qualities determined by shipping companies, such as operational competitiveness and customer relationship quality, and how these then positively affect customer satisfaction through the formation of trust. Therefore, we examine the mediating effect of trust formation among different contractors for shipping services. Design/methodology - In order to examine the shipping company's tangible and intangible service-qualities perceived by the shipper on customer satisfaction and the process of trust formation between contractors, we collected valid data from 114 respondents out of 200 distributed questionnaires. The respondents consisted of domestic freight forwarders who engage with domestic and international shipping and logistics agencies. Descriptive statistics, confirmatory factor analysis, reliability, convergent and discriminant validities, common method bias, and PLS-SEM (partial least square-structural equation model) were analyzed using the program STATA 16. Findings - The findings of this study are as follows. First, our results showed that all hypotheses assumed in this study had statistically significant supporting evidence. Second, it was found that the mediating effect of trust was significant in affecting the quality of intangible service- qualities for customer satisfaction. Third, through supplementary analysis, we found that the global network competitiveness of domestic shipping companies will increase in importance in the future. In conclusion, the theoretical and practical implications of these findings are presented. Originality/value - This study reaffirmed the traditional causal relationship between customer satisfaction and tangible service quality. Additionally, we also contribute to the literature on the understanding of the causal relationship between trust formation and customer satisfaction through intangible interactions from a long-term perspective.

Objectives: Suicide is the leading cause of death among adolescents in South Korea, and depression and personality profiles have been identified as significant risk factors for self-injurious behavior. This study examined the influence of depressive mood and temperament/character on self-injury in adolescents. Methods: A total of 116 adolescents (aged 12-18 years) with a primary diagnosis of major depressive disorder (MDD) and their parents were enrolled in this study. The participants were divided into three groups based on adolescent's self-injury frequency, and their Children's Depression Inventory (CDI), Youth Self-Report (YSR), and Temperament and Character Inventory (TCI) scores were compared. Finally, mediation analysis was conducted to investigate the relationship between suicidal ideation and self-injury. Results: Of study participants, 75.9% answered that they had suicidal ideation, and 55.2% answered that they had engaged in self-injurious behavior in the last six months. There were significant differences in CDI and suicidal ideation among the groups. After adjusting for age and sex, mediation analysis indicated that depressive mood mediated the relationship between suicidal ideation and self-injury. Conclusion: This study emphasizes the importance of evaluating and managing depressive mood severity in adolescents with MDD as these factors partially mediate the transition from suicidal ideation to self-injury.

Objectives The aim of this study is to investigate the association between secondhand smoke (SHS) exposure and depressive symptoms among Korean adults. This study also explored the mediating role of self-rated health (SRH) and perceived usual stress (PUS) in the association between depressive symptoms, suicidal ideation and SHS exposure. Methods Data from the Korea National Health and Nutrition Examination Surveys (KNHANES) in 2014 and 2016 was analyzed for 10539 participants aged 19 years or older. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in the logistic regression analysis with adjustment for the potential confounding factors. We also adopted the mediation analysis method by Hayes and Preacher. Results After adjusting for the potential confounding factors, SHS at home and at public places were associated with depressive symptoms and suicidal ideation among non-smokers. After adjusting for the potential confounding factors, SHS at home and at public places was associated with depressive symptoms and suicidal ideation among non-smokers. Meanwhile SHS at workplaces was associated with depressive symptoms among former smokers and with suicidal ideation among current smokers. There was an additive effect of SHS on depressive symptoms only among non-smokers. SRH mediated the association between SHS and depressive symptoms and suicidal ideation among non-smokers. We did not observe any significant mediating effect of SRH nor PUS on the association between SHS and depressive symptoms among former and current smokers. Conclusions SHS may be associated with depressive symptoms and suicidal ideation in Korean adults. Our study elucidated how SHS interacted with depressive symptoms among non-smokers through the mediation by SRH.

Purpose - Previous studies tried to find antecedents of innovative behavior. However, research on knowledge hiding behavior, psychological mechanism, and perception of organizational justice has been relatively limited. In this sense, this study has investigated the impact of organizational justice on employees' innovative behavior and explored the factors that affect the above relationship. Especially, this study tested the direct effect of organizational justice on innovative behavior. This study also examines the mediating roles of knowledge hiding behavior in this causal relationship. Moreover, the process of organizational justice to innovative behavior is assumed to be influenced by leadership style. Therefore, we examined the moderating effect of authentic leadership on the relationship between organizational justice and knowledge hiding behavior. Design/methodology/approach - For the empirical test, we collected data via a questionnaire survey of a sample of 252 employees from Korean firms. We conducted a hierarchical regression analysis to test hypotheses. Results - The results of the empirical analysis revealed that organizational justice was positively related to innovative behavior and negatively related to knowledge hiding behavior. The results also showed that knowledge hiding behavior negatively mediated the relationship between organizational justice and innovative behavior. In addition, we found the moderating role of authentic leadership. More importantly, we found that the conditional indirect effect of organizational justice on innovative behavior via knowledge hiding behavior was depending on authentic leadership. Uncovering the relationship between organizational justice and innovative behavior through the mediating role of knowledge hiding behavior and the moderated mediating role of authentic leadership has useful theoretical and practical implications. We also suggest directions for future research by providing several limitations.

Purpose - This study is an empirical study on the relationship of Thai consumers' attitude toward Korean Wave with the visit intention of Korean restaurants and a mediation effect of consumption value of Korean restaurants. Design/Methodology/Approach - Data were collected using a structured questionnaire of 245 Thai consumers and the hypotheses presented were verified by regression analysis and structural equation models. Findings - As a result of the empirical analysis, it was found that the higher the attractiveness and favorableness of Thai consumers for K-Wave, the higher the intention to visit Korean restaurants, and the Korean Wave attitude have a positive effect on the functional and symbolic values of Korean restaurants. In particular, the important result that can be presented in this study is that the better the attitude toward K-Wave, the higher the consumption value (functional/symbolic value) of Korean restaurants and the symbolic value plays a significant mediating effect on the relationship of the attitude of K-Wave and visiting intention, while the effect of functional value is not verified. Research Implication or Originality - These results means that in order to lead Thai consumers to a Korean restaurant using K-Wave, a strategy to make Thai ones perceive symbolic value of a Korean restaurant higher would be more effective. The main strategic implication of this study is that a high-end positioning strategy with a high symbolism, which make Korean restaurant as a suitable place as a means to show off one's value (or self) or as a means to show off one's social status (or role) to Thai consumers, will be relatively effective.

Purpose: Nursing informatics competency is used to manage and improve the delivery of safe, high-quality, and efficient healthcare services in accordance with best practices and professional and regulatory standards. This study examined the relationship between nursing informatics competency (NIC), nursing care left undone, and nurse reported quality of care (NQoC) and nursing productivity. A path model for their effects on nursing productivity among clinical nurses was also established. Methods: Data were collected using structured questionnaires answered by 192 nurses working in a tertiary hospital located in J city, Korea, and analyzed using SPSS/WIN 23.0 and AMOS 21.0 program. Results: The fit indices of the alternative path model satisfied recommended levels χ² = .11 (p = .741), normed χ² (χ² /df) = .11, SRMR = .01, RMSEA = .00, GFI = 1.00, NFI = 1.00, AIC = 18.11. Among the variables, NIC (β = .44, p < .001), NQoC (β = .35, p < .001) had a direct effect on nursing productivity. Due to the mediating effect of NQoC on the relationship between NIC and nursing productivity, the effect size was .14 (95% CI .08~.24). Meanwhile, nursing care left undone through NQoC in the relationship between NIC and nursing productivity, has a significant mediation effect (estimate .01, 95% CI .00~.03). The explanatory power of variables was 44.0%. Conclusion: Education and training for enhancing NIC should be provided to improve nursing productivity, quality of care and to reduce missed nursing care. Furthermore, monitoring the quality of nursing care and using it as a productivity index is essential.

Background: This study aims to investigate the effect of lower limb strengthening training combined with electro muscle stimulation on the quadriceps femoris muscle activity of soccer players. Methods: Thirty university soccer players were selected as study subjects and divided into a lower limb strengthening training group combined with EMS (Group I) and a general lower limb strengthening training group (Group II), and 15 subjects were randomly assigned. After receiving general soccer training, subjects in this study additionally mediated lower limb strengthening training combined with EMS and general lower limb strengthening training for 26 minutes, 3 times a week for 8 weeks. Quadriceps femoris muscle activity was analyzed before mediation. Vastus medialis, vastus lateralis, and rectus femoris were measured with maximum isometric contraction in the manual muscle test position in order to analyze leg muscle activity. The same items as above were re-measured and a between-group analysis was conducted after 8 weeks of mediation. Results: As a result of comparative analysis of lower extremity muscle activity between groups, the lower limb strengthening training group combined with EMS showed a statistically significant difference in lower extremity muscle activity compared to the general lower limb strengthening training group. Conclusion: As a result, it was found that lower limb strengthening training combined with EMS was more effective in improving quadriceps femoris muscle activity. Based on this study, we are going to provide basic data on the possibility of using EMS in the field of sports rehabilitation for soccer players.
