Objectives: This study proposes a hypothetical model for job stress, job satisfaction, organizational commitment, and turnover intention through social exchange relations (LMX, TMX) and political skills (LPS) for dental hygienists working in dental clinics hygienists. Methods: A self-administrated questionnaire was administered from April 1 to May 12, 2020, with 171 dental clinic hygienists participating in Seoul, Busan and Gyeongnam. The data were analyzed using SPSS and AMOS statistical analysis programs. Results: First, in the hypotheses testing, a total of 7 of 18 hypotheses were supported. Second, the relatonship between leader-member exchange (LMX) or team-member exchange (TMX) and turnover intention, a full mediating effect of job stress or job satisfaction or organizational commitment on that exchange was found. However, the leader's political skills on the path to turnover intention were not statistically significant. Conclusions: It is considered that education to enhance job skills, support for leisure activities, and time to communicate opinions with each other should be provided to create an organizational culture that satisfies all members, thereby lowering the intention to turnover.

Although research on the leader's or speaker's voice has been continuously conducted, existing research has a single point of view. Sound analysis of voice characteristics has been studied from engineering perspectives, and leadership trait theory has been studied from a business perspective. Convergence studies on leader voice and member cognition are being attempted today. Convergence research on voice has a positive effect on refinement of voice analysis, diversification of voice use, and establishment of voice utilization strategy. This study explains the current flow of research on convergence between speaker's voice and listener's perception, and suggests a direction for the future development of voice fusion research. Furthermore, in connection with AI in the 4th industrial age, new attempts for voice research are sought. First, advances in AI focus on strategically generating the voices needed for individual situations. Second, the voice corrected in real time will support the leader and speaker to utilize the desired voice type. Third, voices through AI based on big data will affect the cognition, attitude and behavior of individual listeners who members, customers, and students in more diverse situations. The purpose and significance of this study is to suggest the way to research the leader's voice recognized by members, and to suggest a method that can be applied in various situations.

Background: The purpose of this study was to examine the moderating effect of resilience and social support to analyze that call center consultants' emotional labor impacts on the burnout. Methods: A survey questionnaire was conducted to people who work at call center in Gwangju and Deagu. The data from 444 were analyzed. Results: The result from the hierarchical multiple regression is as follows. First, deep acting decreased burnout, but surface acting of emotional labor increased burnout. Also, frequency of emotion display, variety of emotion required to be expressed and attentiveness to required display rules increased burnout. Second, Resilience had moderating effect between deep acting and burnout. Third, the moderate effect of interaction of social support from leader with surface action was found at burnout. Also, moderating effect of social support from leader were shown in frequency of emotion display with burnout and attentiveness to required display rules with burnout. Fourth, social support from colleague did not have buffering effect on emotional labor and burnout. Conclusions: It is expected that the moderator variables identified in this study can be used for prevention and treatment of burnout caused by emotional labor.

Communications for mobile sink groups such as rescue teams or platoons bring about a new challenging issue for handling mobility in wireless sensor networks. To do this, many studies have been proposed to support mobile sink groups. When closely looking at mobile sink groups, they can be divided into (multiple) small groups according to the property of applications. For example, a platoon can be divided into multiple squads to carry out its mission in the battle field. However, the previous studies cannot efficiently support the division of mobile sink groups because they do not address three challenging issues engendered by the mobile sink group division. The first issue is to select a leader sink for a new small mobile sink group. The efficient data delivery from a source to small mobile sink groups is the second issue. Last, the third issue is to share data between leader sinks of small mobile sink groups. Thus, this paper proposes a routing protocol to efficiently support the division of mobile sink groups by solving the three challenging issues. For the first issue, the proposed protocol selects a leader sink of a new small mobile sink group which provide a minimum summation of the distance between the new leader sink and the previous leader sink and the distance from the new leader sink to all of its member sinks. For the efficient data delivery from a source to small mobile sink groups in the second issue, the proposed protocol determines the path to minimize the data dissemination distance from source to small mobile sink group by calculating with the location information of both the source and the leader sinks. With regard to the third issue, the proposed protocol exploits member sinks located among leader sinks to provide efficient data sharing among leaders sinks by considering the location information of member sinks. Simulation results verified that the proposed protocol is superior to the previous protocol in terms of the energy consumption.

This study aims to empirically analyze the effects of leadership level and toxic leadership on leadership performance results among male and female military leaders in the Army, and to verify whether the leader's gender has a moderating effect in this process. Additionally, by comparing and analyzing the leadership level, toxic leadership, and leadership performance results of female military leaders by position, this study seeks to examine the characteristics of female military leadership according to position. The research model was established with leadership level and toxic leadership as independent variables, leadership performance results as the dependent variable, and the leader's gender as a moderating variable. Data were collected through a survey of 216 male and female officers serving in the positions of platoon leader, company commander, and battalion commander in the Army. The collected data were analyzed using descriptive statistics, reliability analysis, correlation analysis, and hierarchical regression analysis. The results showed that leadership level had a significant positive effect on leadership performance results, while toxic leadership had a significant negative effect. The leader's gender moderated the relationship between leadership level and leadership performance results, with female leaders receiving lower evaluations than male leaders at the same level of leadership competency. Gender also moderated the relationship between toxic leadership and leadership performance results, with female leaders exhibiting the same level of toxic leadership receiving lower performance evaluations than male leaders. In the comparative analysis of female military leadership characteristics by position, the leadership level of the platoon leader and company commander groups was not significantly different from that of male soldiers, but the battalion commander group showed slightly lower leadership competency compared to male soldiers. Based on these results, this study suggests ways to improve the leadership level of female military leaders, reduce toxic leadership, and prepare support measures to strengthen the leadership competency of female military officers at the battalion commander level and above from policy, institutional, and educational perspectives.

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.

Professionalizing the teaching workforce has been recognized as one of the primary factors to reforming public education. In response to this challenge, it has been emphasized that an educational leader's role is to support professional learning communities more effectively. Although the academia of educational administration has increasingly drawn the significance of a teacher's professional development, understanding of an educational leader's role and contribution to this effort is quite limited and unclear. This article examines what factors and barriers affect teachers' participation in professional learning communities from the voices and experiences of teachers. The analysis found 1) identification, 2) autonomous will, 3) practical solution for factors to participation and 1) lack of theoretical foundation, 2) financial burden, 3) insufficient time for barriers to participation. In conclusion, the author suggests the strategies for an educational leader who has an important role in developing a teacher's professionalism: 1) create a strong network of university professors and other experts for career advice, 2) make an institutional effort to stimulate teachers' motivation to learn; 3) decrease the teachers' workload, 4) build a synthesized and consolidated system to establish communities.

This study explores the agency of a student leader, expressed through efforts to distribute power and encourage participation in elementary scientific modeling classes. The study also analyzes the context in which the leader's agency was expressed and the context in which the development of a collective agency was constrained. The participants were 22 fifth-grade students. The leader's agency was analyzed by examining his words and actions. As a result, at the outset of the study, the leader had the most power, performing all the activities as the sole authority in a non-cooperative participation pattern. However, with reflection and help from the researcher, the leader recognized the problem and facilitated the participation of other students. He developed an identity as a teacher and demonstrated the agency. The leader's agentic behaviors can be categorized into three aspects. First, regarding the cognitive aspect, the leader helped other students participate in modeling by sharing his knowledge. Second, regarding the normative aspect, he made rules to give all students an equal voice. Third, regarding the emotional aspect, the leader acknowledged the contribution of the students, increasing their confidence. The leader's agency temporarily helped the group to overcome the student hierarchy, facilitating a cooperative participation pattern. However, the development of a collective agency was constrained. The power of the leader was partially redistributed, and the other students did not position themselves as equal to the leader. To support the leader's agency to develop into a collective agency, it is necessary to redistribute the power of the leader more equally and to change the recognition of students.
