The Korean Ministry of Education has emphasized the convergent ability for human resource cultivating the development of science and technology in the future. Based on this, Korean STEAM education aims to enhance students' interest and their understanding of science and technology as well as to develop students' convergence thinking and problem-solving skills. Through the camp for gifted students, students are generally introduced to produce self-directed outputs in order to solve the problem in everyday life. In this study, the author aims to find out whether the gifted high school students' creative leader competency and STEAM literacy changed after they experienced STEAM-based camp. 517 gifted students from 52 high schools in the Metropolitan city region join the camp, which is focused on generating student-centered outputs for problem-solving in daily life context. Before and after the camp, the creative leader competency and the STEAM literacy of participants were tested and compared. From the result, we found that the gifted high school students' creative leader competency and STEAM literacy improved after participating in the STEAM camp. In particular, all the sub-factors except for the social value pursuit domains in the social characteristic area of creative leader competency and the areas of creativity, respect, and communication in STEAM literacy increased. Educational implications will be discussed.

The purpose of this study was to examine how a leader's organizational citizenship behavior (OCB) affects subordinates' interpersonal citizenship behavior (ICB) and job stress levels. A leader's OCB involves taking-charge behavior, loyal boosterism, and the industry. We hypothesized that leader-member exchange (LMX) would mediate the relationship between leader's OCB and subordinates' ICB and job stress level. We tested the model using a sample of 293 employees from different organizations from September 2019 until November 2019. We conducted confirmatory factor analyses of the variables and analyzed the data by using structural equation modeling. We also conducted a CFA to assess the fit of a three-factor model for the leader's OCB items. Empirical findings show that LMX fully mediated the effect of leader's OCB on employees' ICB and job stress level. Leader's OCB had a positive effect on LMX. Moreover, LMX had a positive effect on employees' ICB but had a negative effect on job stress. We found support for our hypotheses that leader's OCB is positively related to ICB but negatively related to job stress, and this relationship is mediated by LMX. We discuss limitations, implications for practice, and future research.

This study attempted to reveal the influence of the exchange relationship (TMX) between Pilates leaders and members on job performance. Accordingly, from April 1 to July 12, 2023, 82 lines of couple data (164 people: 82 leaders, 82 members) were sampled and the following results were derived. First, the higher the leader exchange relationship, the higher the leader's job performance, and the higher the member exchange relationship, the higher the leader's job performance. Second, it can be seen that the higher the leader exchange relationship, the higher the member's job performance, and the higher the member exchange relationship, the higher the member's job performance. Therefore, it can be seen as a result of reflecting the systematic demand for exchange activities because the dependent relationship leads to active job participation through mutual relationships with colleagues.

This study examines the relation between the quality of leader-member relationship and operational performance of processing enterprises employees in Vietnam, while job satisfaction and innovation are as a mediator variable. In depth interviews are first conducted with five managers and professional workers in five processing enterprises to determine the latent variables and build the structured questionnaire with observed variables. A quantitative survey with 438 employees and managers from 300 processing enterprises was carried out. The method of exploratory factor analysis (EFA), Cronbach's alpha analysis, and confirmatory factor analysis (CFA) was used to test the reliability, the convergent nature, and the consistency of the concepts. Structural equation modeling (SEM) is used to test the proposed model. The result shows that job satisfaction, innovation and operational performance have positive effects on the quality of leader-member relationship. The relationship between leaders and members had indirect impact on employee's operational performance via their job satisfaction and innovation, which illustrates a mediator role of job satisfaction and innovation for employees' performance. The findings of this study suggest that managers need to focus on developing relationship with employees to improve their satisfaction, innovation and performance.

Purpose: The purpose of this study was to analyze the effects of a walking leader program on changes in walking knowledge and self-efficacy. Methods: The subjects were 276 participants who participated in the nationwide walking leader program 9 times from May to September in 2008. Data were collected before and after the program by an organized questionnaire. Results: 1) Knowledge related to walking exercise increased significantly to 4.14 point from 2.90 point after the program (t=-20.70, p<.001). 2) Self-efficacy related to walking exercise increased significantly to 4.08 point from 3.40 point after the program (t=13.93, p<.001). 3) Significant factors that affected knowledge and self efficacy before the program were regular exercise and subjective health status. The history of chronic disease and smoking were significantly affecting factors to knowledge and self-efficacy after the program. Conclusion: The walking leader program promoted the participants' walking knowledge and selfefficacy. It is necessary to develop more specific programs tailored to socio-demographic characteristics of participants and to make efforts to increase participants with active public information.

As interest in autonomous ships continues to grow, researchers around the world are dedicating themselves to the development of relevant technologies. However, these technologies are not yet perfect. Several technical problems remain unresolved. To address these problems, this study presents the implementation of a ship trajectory algorithm for group navigation, where followers can navigate by following the trajectory of a leader. The algorithm works by storing the leader's trajectory as a follow-point and by calculating the azimuth using the line-of-sight guidance law to reach it. A course-keeping controller based on PD control is implemented to follow the target course and a speed control algorithm is designed to prevent collisions. Sea experiments were conducted using 1 m class small RC model boats to verify the proposed algorithm. The follower successfully navigated by following the leader's trajectory and maintained the designated distance to the forward boat. This study is significant in that it implements an algorithm for the follower to follow the trajectory of the leader rather than directly following it as in conventional methods, and verifies it through sea experiments.

The performance of transmission lines and its shielding design during a lightning phenomenon are quite essential in the maintenance of a reliable power supply to consumers. The leader progression model, as an advanced approach, has been recently developed to calculate the shielding failure rate (SFR) of transmission lines using geometrical data and physical behavior of upward and downward lightning leaders. However, such method is quite time consuming. In the present paper, an effective method that utilizes artificial neural networks (ANNs) to create a metamodel for calculating the SFR of a transmission line based on shielding angle and height is introduced. The results of investigations on a real case study reveal that, through proper selection of an ANN structure and good training, the ANN prediction is very close to the result of the detailed simulation, whereas the Processing time is by far lower than that of the detailed model.

The purpose of this study is to examine the effects of nurses' emotional labor and the importance of leaders' emotional intelligence roles by verifying them with job satisfaction and organizational commitment for 396 nurses at 8 university hospitals in Seoul and Gyeonggi province. It was found that emotional labor had a negative relationship with job satisfaction and organizational commitment. And leaders' emotional intelligence has a significant positive relationship with job satisfaction and organizational commitment. However, leaders' emotional intelligence has no moderation effect on emotional labor and dependent variables. As this study shows that emotional labor and leader's emotional intelligence affect organizational effectiveness of hospital nurses, it would be important to not only manage members' emotional labor but to also develop the emotional intelligence of both leaders and the staff.
