This study focused on the development of a simulation-based educational program for communication, targeted to prevent safety accidents of patients. Application of the program to nurses working in public medical institutions was assessed to identify the effects of the program in terms of communication skill, self-efficacy, critical thinking disposition, and problem solving ability of nurses, before and after completion of the education. Method: A total of 32 nurses, working in hospitals designated as public medical institutions, were selected as subject participants in the present study. Data were collected during the period August 19 to 20, 2019, and analyzed by SPSS 23.0. Results: Results obtained from the present study reveals significant efficacy of the educational program, in respect of improved communication skill, self-efficacy, and problem-solving ability. On completion of the educational program, we observed an increase in the critical thinking disposition of nurses, although it was statistically insignificant. Conclusions: We believe that the educational program developed in the present study can be exploited as a foundation for developing other programs intending to improve the communication skill of nurses employed in clinics of public medical institutions, targeted to prevent occurrence of safety accidents of patients.

This paper introduces a new multi-product multi-period multi-objective aggregate production planning problem. The proposed problem is modeled using multi-objective mixed-integer mathematical programming. Three objective functions, including minimizing total cost, maximizing customer services level, and maximizing the quality of end-product, are considered, simultaneously. Several constraints such as quantity of production, available time, work force levels, inventory levels, backordering levels, machine capacity, warehouse space and available budget are also considered. Some parameters of the proposed model are assumed to be qualitative and modeled using fuzzy sets. Then, a fuzzy goal programming approach is proposed to solve the model. The proposed approach is applied on a real-world industrial case study of a color and resin production company called Teiph-Saipa. The approach is coded using LINGO software. The efficacy and applicability of the proposed approach are illustrated in the case study. The results of proposed approach are compared with those of the existing experimental methods used in the company. The relative dominance of the proposed approach is revealed in comparison with the experimental method. Finally, a data dictionary, including the way of gathering data for running the model, is proposed in order to facilitate the re-implementation of the model for future development and case studies.

The role of traditional universities has been emphasized as a career path to advance into society. Recently, it has become a new paradigm of university education by emphasizing entrepreneurship as a career aspect. While entrepreneurship education is constantly expanding for college students, relatively few young people choose to start their own business. Despite the fact that the government is continuing to expand the university's entrepreneurship education, there are very few achievements that lead to actual entrepreneurship and student start-up There is still a lack of research on ways to cultivate creative talents and increase practical entrepreneurial intention. The results of this study are as follows: First, the effects of creativity competency education on self-efficacy and entrepreneurial intention were analyzed. The effect of self-efficacy on the entrepreneurial intention. Finally This study examined the effects of social support (parent support) between self-efficacy and entrepreneurial intention. This study used 393 samples in August 2016 for university students who received entrepreneurship education. The results showed that the ability of communicative communication and creative problem solving had a positive effect on self-efficacy. On the other hand, innovative work behavior abilities did not directly affect self-efficacy. In addition, creative problem solving ability and innovative work behavior ability had a positive effect on the entrepreneurial intention. On the other hand, the ability to communicate in a collaborative manner has no direct effect on the entrepreneurial intention. In addition, self-efficacy has a positive effect on the entrepreneurial intention. Finally, the adjustment effect of social support (parent support) between self-efficacy and entrepreneurial intention has no effect. The implications of this study are empirically verified the effectiveness of creativity capacity through entrepreneurship education and the result of meaningful research that the social support through cooperation of parents is indispensable in order to increase the actual starting will of college students. Therefore, universities need to establish entrepreneurship education programs for their parents in order to increase the willingness of college students to start-up. This study can be used as a meaningful basic data for establishing policy for student start - up and suggesting the right direction of entrepreneurship education.

The software centered world following the fourth industrial revolution is rapidly approaching us. Countries around the world attach importance to software's ability as one of the key elements for training future human resources. In order to train software centered human resources, each university has designated Software Education as an essential curriculum for not only major but also non-majors. In the past Software Education was an education for a major, but recent Software Education was changed to the essential education that is necessary for all living in the software centered world. In the past the curriculum was focused on software development and implementation-oriented education, but recent curriculum emphasizes sequential arranging and thinking of problem solving. In order to reflect trends in recent Software Education in detail, we integrate Software Education with major concept of Computational Thinking. In this paper, we analyzed the effect of the main concept of Computational Thinking on Software Education for non-majored learners who received Software Education based on Computational Thinking (here refers to learners who major in humanities, social sciences and arts). In addition, research models of satisfaction, self-efficacy, and occupational change was established as the elements of Software Education, and it was found that there was a relation between Computational Thinking and Software Education.

The present study investigated the developmental pattern of Korean mothers' depressive symptoms from a week prior to birth through four months postpartum in a nationally represented survey sample in Korea, using a Latent Growth Curve model. Mother-reported four factors-maternal self-efficacy in parenting, father's participation in childcare, a number of hours mothers worked per week, child's emotional temperament-were examined as the predictors of depressive symptoms over time in the context of Korean culture. Effects of maternal depressive trajectories on their infants' developmental outcomes at the first year were also examined. Findings were as follows: First, mothers' reports of depressive symptoms decreased at the first month after birth and then increased again during the first 4 months postpartum. Second, mothers' perceived low spousal involvement in childcare, low parental self-efficacy, and their infants' difficult temperament at four-month old had significantly positive relations to the initial level of maternal depressive symptoms whereas the low spousal involvement in childcare and low maternal self-efficacy factors significantly predicted the changes of trajectories of maternal depressive symptoms. Third, the trajectories, in turn, predicted warm and responsive maternal parenting style at the fourth month. Subsequently, the parenting style had a significant longitudinal impact on the development of children's communication, problem-solving, and personal-social abilities. Based on these findings, awareness, preventive and interventional programs might be built to facilitate Korean mothers suffering severe postpartum depressive symptoms and further promote optimal early development of Korean children.

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.

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.
