The purpose of this study is to verify the mediating effects of self-efficacy in correlation between conscientiousness and neuroticism among the Big Five personality traits and stress coping strategies. The following two study questions were formulated. Study Question 1: What is the correlation between the Big Five personality traits, stress coping strategies, and self-efficacy Study Question 2: Among the Big Five personality traits, conscientiousness and neuroticism are selected as clinically very meaningful variables that represent mental health in undergraduates. If so, does self-efficacy play a mediating role in the correlation between conscientiousness and neuroticism and stress coping strategies To verify the two study questions, the Big Five personality traits, stress coping strategies scale, and self-efficacy scale were measured for a sample of 462 freshmen attending D University located in Chungcheong. First, according to the results of correlation analysis, neuroticism and self-efficacy showed a negative correlation, and conscientiousness showed a positive correlation. Regarding the Big Five personality traits and stress coping strategies, conscientiousness showed a negative correlation with avoidance-orientation among stress coping strategies. Neuroticism showed a negative correlation with social support and problem solving-orientation among stress coping strategies. Second, according to the results of analyzing the mediating effects of self-efficacy through hierarchical regression analysis, self-efficacy exerted partial mediating effects only in correlation between neuroticism and avoidance-orientation. This study is significant in its anticipation of undergraduates' stress coping, personality factors can be usefully employed as psychological constructs, and particularly, when an undergraduate reveals the neuroticism factor, which is one of the predictors for mental health, and the tendencies of avoidance among stress coping strategies, educational interventions for self-efficacy are needed to reduce their mental stress.

This study aimed to develop SSTPBL (Student-led Simulation with Team and Problem-Based Learning), whichcombines TBL and PBL with a student-led method to strengthen knowledge application, nursing diagnosis ability, and collaboration ability among the core competencies of nurses. Then, SSTPBL was applied to nursing students, and the results were assessed. The data was collected from September 15, 2022, to December 21, 2022, with structured questionnaires and focus group interviews with 51 fourth-year nursing students at a university in A City. The collected data were analyzed using SPSS version 25.0 and topic analysis. As a results, it was effective in simulation experience satisfaction(t = 3.51, p < .01), vSim experience satisfaction(t = 3.50, p < .01), preparation as a prospective nurse(t = 3.73, p < .01), learning self-efficacy(t = 3.87, p < .01), collaborative self-efficacy (t = 4.30, p < .01), problem-solving ability(t = 5.26, p < .01), educational satisfaction(t = 3.54, p < .01), digital health equity(t = 2.18, p < .05). Through the qualitative data's topic analysis, six main topics were derived. The main topics were 'similar to clinical practice', 'difficulty in immersion', 'learning through others', 'learning through self-reflection', 'improving confidence through new experiences' and 'new teaching methods'. Based on the results of this study, it is expected that SSTPBL can be used in various ways as a new training method for prospective nurses in the face of growing clinical practice restrictions after the pandemic.

The Goal of SW education is to improve computational thinking. Especially, non computer majors need to apply computational thinking to their problem solving in their fields after computational thinking class. In this paper, we verified what factors affect the improvement of computational thinking through mixed research method after teaching computational thinking to non major students. Also, we analysed the characteristics of initial learning transfer of computational thinking, and establish the reason about he validity and justification for non major in SW education. The result shows learning satisfaction, learning transfer motivation, and self-CT efficacy affect the perception about improvement of computational thinking. Also, we found that there is application of computational thinking was coming up with problem solving process because the initial learning transfer process of computational thinking has characteristics about concepts and practices of it in programming steps. The effectiveness and learning transfer process of computational thinking for non majors will give the validity and justification to teach SW education for all students.

The objective of this study is to identify the characteristics of high performer among R&D professionals and to examine the effects of LMX(Leader-Member Exchange) and TFL(Transformational Leadership) on job satisfaction or organizational commitment. The empirical result shows that; 1) when compared with the low performers of R&D professionals, the high performers have more proactive personality such as risk-taking propensity, self-efficacy, need for achievement, 2) the high performers have more innovative problem-solving style, 3) the impact of LMX and TFL on job satisfaction or organizational commitment is significant and positive, 4) the augmentative effect of TFL over LMX on job satisfaction or organizational commitment exists for low performer but does not exist for high performer. Based on the result, the theoretical and practical implications are discussed.

One of the problems faced in implementing cellular manufacturing systems is machine-part group formation. This paper proposes machine-part grouping algorithms based on Self-Organizing Map(SOM) neural networks and K-Means algorithm in cellular manufacturing systems. Although the SOM spreads out input vectors to output vectors in the order of similarity, it does not always find the optimal solution. We rearrange the input vectors using SOM and determine the number of groups. In order to find the number of groups and grouping efficacy, we iterate K-Means algorithm changing k until we cannot obtain better solution. The results of using the proposed approach are compared to the best solutions reported in literature. The computational results show that the proposed approach provides a powerful means of solving the machine-part grouping problem. The proposed algorithm Is applied by simple calculation, so it can be for designer to change production constraints.

Adolescent psychosocial smoking prevention programs have been successful, but limited in the magnitude of program effects on the reduction of smoking behaviors. This is primarily due to the mixed results of independent studies with program variations. This systematic, quantitative research synthesis is designed to identify program key factors that are likely to increase program effects. The present study examined school-based psychosocial smoking prevention programs (1978-1997)among students in grades 6 to 12 in the United States. Theoretical formulations in this analysis of mediating effects posit that program impact on knowledge and/ or skills is associated with less smoking behaviors among program participants. Knowledge factors investigated in this study included health effects, social consequences, social influences, and social norms. Skill factors included affective skill, self-efficacy, assertiveness, self-control, problem solving, and refusal skill. The findings from this study highlight the importance of social consequences knowledge factor and assertive communication skill factor in decreasing adolescent smoking behaviors.

In this study, we analyzed the factors that affect public awareness campaigns on social media platforms and developed an integrated model for measuring the persuasiveness of environmental social media campaigns. A survey questionnaire was created and distributed on Facebook with the goal of reaching individuals in their 20s and 40s in Vietnam, and 395 valid replies were gathered. The findings showed that the STOPS was reconfirmed as a suitable theoretical framework for analyzing the public's behaviour intention to conduct information related to the issue of fine dust, especially on social media. Furthermore, it also showed that social media efficacy has a moderating effect on the relationship between public's situational recognition and informational behaviour intention. This suggested that through social media platforms, personal characteristics play a vital part in developing effective environmental campaigns. Implications for both theory and practice were discussed.
