Over the last 70 years, South Korea has gone through countless provocations from North Korea. Provocation is something that must be delicately calculated before the actual action, since it can be extended to a serious conflict. Among the possible factors, this paper focuses on the leader's characteristic, because 1) under North Korean dictatorship, the leader's thoughts are critical influence to policies and 2) personal characteristic, especially if it is the dictator's, hardly changes even when the external circumstances change. The purpose of this paper is in analyzing the correlations between North Korean leader's characteristics and provocation pattern. First, three generations of Kim Il-sung, Kim Jong-il, and Kim Jong-un's personal characteristics will be described. Next, particular provocation features in respective leader's period will follow. Lastly, how each leader's characteristic and concerns were reflected on the provocations will be analyzed.

In this paper, we study the conflict management plan of the organization in the age of convergence. More specifically, we reveal the impact of the conflict according to behavior of the leader. To this purpose, The behavior of the leader were classified as Supportive Leader and Controlled Leader, and forms of Resistance wert classified as Functional Resistance and Dysfunctional Resistance that results of the conflict. Also, Psychological Contract Violation and Breach was set up as a mediate variable. The results were as follows. First, When employee resistance comes up in the organization, Support behavior of Leaders leads to desirable changes in the organization through the functional and constructive resistance. In contrast, Controlled behavior of Leaders leads the destructive and dysfunctional resistance of employee. Second, Since the perception that the follower is receiving assistance to leaders, it reduces the perception of psychological contract violation, but Controlled leader is largely perceived as the Psychological Contract Violation to the followers. Third, Supportive Leader is not influence the affect of employee, and They resolve the Conflict in objective and positive way. Therefore, the results of this study have many theoretical and practical implications.

This paper deals with the energy saving problem of the follower aircraft in the loose leader-follower formation geometry in which the lateral separation between formation members is more than a wingspan of the leader aircraft. This formation geometry offers no drag benefit, but has a strategic advantage. In the case of loose formation flight, the follower aircraft usually consumes more energy than the leader aircraft because the follower aircraft should use more thrust to maintain given formation geometry, especially during the turning phase from the outside of the leader"s flight path or join-up phase. A formation control scheme based on the energy maneuverability is proposed in this paper. To design the proposed control law, the velocity command is designed using feedback linearization for the horizontal formation geometry and then coverts it to the altitude command using the energy equation. Numerical simulation is performed to verify the effectiveness of the proposed controller.

The purpose of this study is to verify the correlation between leader's machiavellianism and turnover intention. To this end, we tried to investigate the overall mechanism of the research model through the mediating effect of hindsight bias. To verify the hypothesis, surveys were conducted twice with 335 employees working at companies with more than 300 employees in various occupations. As a result of the study, first, it was found that the machiavellianism of the leader had a positive significant effect on the employee turnover intention. Second, it was found that hindsight bias had a positive significant mediating effect between the leader's machiavellianism and employee turnover intention. It can be inferred that the higher the machiavellianism tendency of the leader, the higher the hindsight bias is experienced and the negative impact on the effectiveness of the organization, the higher the employee turnover intention. Therefore, this study in-depth verifies the mechanism between the leader's machiavellianism, hindsight bias, and employee turnover intentions, suggesting new implications from a perspective different from the existing research flow, and suggesting future research tasks and limitations on the role of leaders.

The purpose of this study was to investigate the elementary school pre-service teachers' and in-service teachers' and STEAM leader school teachers' difficulties and requirements in the relation to STEAM Education. For this study, 49 pre-service teachers, 57 in-service teachers, 16 leader school teachers in G Area were selected. And they conducted the survey. The results of this study were as follows. First, in order to minimize elementary teachers' physical burden actually, it is necessary to distribute STEAM teaching materials including various and specific programs to the schools in the booklet. Second, for the fast and effective spreading of STEAM, it also should be permitted the pre-service teachers to access STEAM homepage, which is limited to teachers. Third, we should make circumstance to research on STEAM through collaboration with colleagues freely. Therefore, we should give intensive training and consulting opportunities to science teacher. Because they who is getting stronger in this field to do this can furnish other colleagues to teaching tips and information in the relation to STEAM education. By all this fulfillment simultaneously, STEAM will be settlement in elementary school in the short period.

Purpose: The purpose of this study was to develop and evaluate a school-based peer leader centered smoking prevention program. Methods: Non-equivalent control group with a pre/post-test design was used. Students (n=174) in two boys' junior high schools located in D city, Korea participated with 85 being selected for the experimental group and 89 for the control group. Five sessions were given to the experimental group and a 50 minute lecture to the control group. Knowledge, attitude, nonsmoking intention, and nonsmoking efficacy were measured for the both experimental and control group at two weeks before the program and one month after the program was completed. Data were analyzed using ${\chi}^2$-test, Fisher's exact test, independent t-test and paired t-test with the SPSS 21.0 program. Results: The experimental group showed higher overall knowledge, negative attitude toward smoking, and higher non-smoking intention and efficacy. After receiving the school based peer leader centered smoking prevention program scores for attitude toward smoking and nonsmoking efficacy increased in the experimental group were higher than in the control group. Conclusion: The school-based peer leader centered smoking prevention program needs longitudinal evaluation, but from this study, there is an indication that this program can be used with junior high school students and effectively change students' attitude toward smoking and promote nonsmoking efficacy.

This study expanded the superiority of random leader selection procedure on group decision-making task to actual group performance task, and examined the interaction effects of leader selection procedure(LSP) and collective efficacy(CE) on group performance. 2(LSP: formal/random)×2(CE: low/high) between subject design was used. The result revealed the significant main effect of LSP, which showed that groups with random leader performed better than those with formally selected leader. Further, significant interaction effect of LSP and CE revealed that when group's CE was high, group with random leader performed better than group with formally selected leader, and the difference between two groups was not significant when group's CE was low. These results suggested that LSP should not impair shared social identity of the group in order to maintain the positive effect of CE on group performance. The necessity for expanding these results to work team was discussed.

The Korean Ministry of Education has emphasized human resource development with creative and convergent ability for future science and technology development. Korean STEAM Education aims to enhance students' interest and their understanding of science and technology as well as to develop students' creative problem-solving skills. Through STEAM R&E project, students experience self-directed research in order to solve the problem in the context of everyday life. In this study, we aim to find out whether the creative leader competency of high school students changed after they experienced the STEAM R&E project. The creative leader competency consisted of three domains: cognitive, affective, and societal domain. We measured the creative leader competency using the questionnaire scales. The questionnaire was administered to 612 high school students who participated in the 2016 STEAM R&E project. Pre- and post- test scores were collected, and we analyzed it. We compared the mean difference between pre- and post- test scores as well as the mean differences among science high school, gifted school, science core school, and general high school. From the result, we found that all student' creative leader competency improved after participating in the STEAM R&E project in all three domains. The result also showed that students' test scores of science high school and gifted school showed no significant mean differences, while student's scores of both science core school and general high school improved significantly. From the results, we concluded that STEAM R&E activities could be an effective tool in cultivating creative leader competency, especially for general high school students and science core school students. We also suggested that further researches are needed to find how we could enhance students' creative leader competency.
