Entrepreneurial hope plays an important role in entrepreneurship, but theoretical and practical understanding of what it is and what it does is lacking. This study examined the effects of entrepreneurs' hope on their emotional exhaustion and psychological well-being. Psychological well-being was classified into three dimensions: self-acceptance, personal growth, and positive relationships. Data were collected from 156 CEOs of entrepreneurial firms. Results of this study indicated that entrepreneurs' hope was negatively related to emotional exhaustion, but positively related to self-acceptance, personal growth, and positive relationships. Results also indicated that emotional exhaustion was negatively related to self-acceptance, personal growth, and positive relationships. Finally, the theoretical and practical implications of the results were discussed.

We develop a mathematical model for the obesity dynamics to investigate the long term obesity trend with the consideration of psychological and social factors due to the increasing prevalence of obesity around the world. Many mathematical models for obesity dynamics adopted the modeling idea of infectious disease and treated overweight and obese people infectious and spreading obesity to normal weight. However, this modeling idea is not proper in obesity modeling because obesity is not an infectious disease. In fact, weight gain and loss are related to social interactions among different weight groups not only in the direction from overweight/obese to normal weight but also the other way around. Thus, we consider these aspects in our model and implement personal weight gain feature, a psychological factor such as body image dissatisfaction, and social interactions such as positive support on weight loss and negative criticism on weight status from various weight groups. We show that the equilibrium point with no normal weight population will be unstable and that an equilibrium point with positive normal weight population should have all other components positive. We conduct computer simulations on Korean demography data with our model and demonstrate the long term obesity trend of Korean male as an example of the use of our model.

Methods: Participants were 166 nurses who had worked for more than six months in the integrated nursing care service wards of three general hospitals located in B city. Data were collected from July 15 to August 30, 2022 using structured questionnaires and analyzed by T-test, ANOVA, Scheffé test, Pearson's correlation coefficients and multiple linear regression using the IBM SPSS/WIN 25.0 statistical program. Results: Factors affecting the nursing performance of participants were age (β=.58, p<.001), positive psychological capital (β=.41, p<.001), and social support (β=.28, p<.001). The total explanatory power of these variables for nursing performance was 55.8%. Conclusion: The results of this study suggest the need for programs that improve psychological capital and social support while considering nurse's age to enhance their performance in nursing integrated service wards.

Purpose : This study aimed to investigate the impact of clinical reasoning competence, positive psychological capital, and nursing work environment on nursing performance of intensive care unit (ICU) nurses in tertiary general hospitals. Methods : Data were collected from 169 ICU nurses in tertiary general hospitals in Busan, South Korea, from July 27 to August 15, 2023, using a self-report questionnaire. After excluding 12 questionnaires with insufficient responses, 157 responses were analyzed. Descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis were employed. Results : Factors influencing nursing performance included clinical reasoning competence (β=.51, p <.001), hope as a subfactor of positive psychological capital (β=.31, p <.001), and the nursing foundations for quality of care in the nursing work environment (β=.21, p <.001). The explanatory power of the regression model was 62% (F=87.41, p <.001). Conclusion : The study underscores the importance of improving clinical reasoning competence among ICU nurses to enhance nursing performance and foster a hopeful attitude through reflective practices and personal growth. Organizational interventions, such as educational and psychological support programs, along with creating a supportive nursing environment, are crucial for improving nursing performance among intensive care unit nurses.

This study focused on whether employees' perceived leader's creativity has a significant effect on employees' job satisfaction and innovative behavior. In addition, this study analyzed the mediating effect of positive psychological capital and creative self-efficacy in the relationship between perceived leader creativity and employee satisfaction with the job or innovation behavior, and analyzed the moderated mediating effect of team cohesion. This study conducted confirmatory factor analysis and path analysis for each factor using the measurement tool verification method using the SmartPLS 3.0 structural equation model, and empirically analyzed the research model. As a result, it was found that the creativity of employees' perceived leaders did not directly significantly affect employees' job satisfaction and innovation behavior. However, it was found that positive psychological capital significantly mediated the relationship between perceived leader creativity and job satisfaction or innovative behavior. In addition, positive psychological capital and creative self-efficacy have a complete double-mediation relationship between the employees' perceived leader's creativity and employees' innovative behavior. However, positive psychological capital and creative self-efficacy don't have a double-mediation relationship between the employee's perceived leader's creativity and employees' job satisfaction. Finally, Team cohesion was found to moderate the relationship between perceived leader creativity, positive psychological capital (or creative self-efficacy). However, the research model that the moderated mediating effect of team cohesion on the relationship between leader's creativity, the mediating variables(positive psychological capital and creative self-efficacy), and job satisfaction (or innovative behavior) was significant only for groups with high team cohesiveness. This study examined the needs of the times for the importance of creativity of perceived leaders and analyzed the relationship between factors influencing job satisfaction and innovation behavior of organizational members. The study is meaningful in that it suggested a plan to establish a specific organizational strategy to enhance positive psychological capital and creative self-efficacy.

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.
