  • Sports participation can contribute to organization members' work-life balance and work motivation in order to increase performance. Based on the achievement motivation theory, this study tested the effect of sports participation on leaders' effectiveness and employees' performance. Data was collected from 213 leaders and subordinates in the South Korean army. Results indicated that leader effectiveness mediated the positive relationship between sports participation of leaders and subordinates' outcomes, such as task performance and OCB. We also found that sports participation of subordinates moderated the positive relationship between leader effectiveness and subordinates outcomes (i.e., task performance and OCB). These findings further suggest that sports participation plays an important role for leaders and subordinates to increase leader effectiveness and in/extra-role behaviors.

  • To connect a mobile ad hoc network (MANET) with an IP network and to carryout communication, ad hoc network node needs to be configured with unique IP adress. Dynamic host configuration protocol (DHCP) server autoconfigure nodes in wired networks. However, this cannot be applied to ad hoc network without introducing some changes in auto configuration mechanism, due to intrinsic properties (i.e., multi-hop, dynamic, and distributed nature) of the network. In this paper, we propose a scalable autoconfiguration scheme for MANETs with hierarchical topology consisting of leader and member nodes, by considering the global Internet connectivity with minimum overhead. In our proposed scheme, a joining node selects one of the pre-configured nodes for its duplicate address detection (DAD) operation. We reduce overhead and make our scheme scalable by eliminating the broadcast of DAD messages in the network. We also propose the group leader election algorithm, which takes into account the resources, density, and position information of a node to select a new leader. Our simulation results show that our proposed scheme is effective to reduce the overhead and is scalable. Also, it is shown that the proposed scheme provides an efficient method to heal the network after partitioning and merging by enhancing the role of bordering nodes in the group.

  • As social media has become a part of daily life, new types of online opinion leaders are emerging, and in turn, changes in traditional fashion leaders and leadership are expected. Considering such changes, this study attempted to reexamine fashion leader types and influence characteristics from the perspective of college students as fashion followers. Students were asked to write an essay identifying their fashion leader and how and why they were influenced by him or her. Sixty essays entitled "My Fashion Leader" were collected and content-analyzed. A total of 78 fashion leaders were identified and categorized into four types including celebrities, social media influencers, friends/family/acquaintances, and people seen on the street in order of frequency. Influence characteristics of the identified fashion leaders included superiority, role model, similarity, and familiarity. Similarity was observed across all types of fashion leaders, while superiority and familiarity were identified for celebrities and friends/family/acquaintances, respectively. The results imply that celebrities, mostly those from the TV, movie, and music industries, are still important as fashion leaders in society regardless of their communication style, while friends/family/acquaintances as opinion leaders within a consumer group are important to provide information, advice, and help. However, social media influencers between the two groups are expanding the influence.

  • An alternative method for team diversity studies is to examine demographic faultlines. A concept of demographic faultline enables us to better understand team dynamics with multidimensional diversity. This study suggests the demographic faultline as a new situational factorto influence the relationship between leader teamwork behaviors and a climate of support for innovation. When subgroups divided by demographic faultline are homogeneous within them and heterogeneous between them, the homogeneity may increase intimacy in each subgroup while the heterogeneity may increase exclusiveness between those subgroups. We argued that a leader could play an important role to build a cooperative relationship between faultline-based subgroups and highlight positive aspects of developing and maintaining subgroups in organizations. With a sample of 81 teams (558 employees), it was examined how leader teamwork behaviors would affect a team-level climate of support for innovation and how this relationship would be moderated by each team's demographic faultline (gender, age, and educational specialty). As predicted, it was found that there was a significant positive relationship between each leader's teamwork behaviors and each team's climate of support for innovation. In addition, this relationship was stronger for teams with strong faultline than with weak faultline. Our findings and their implications were further discussed.

  • Purpose: The purpose of this study was to describe and understand elementary school health teachers' role perception in their own perspectives. Methods: Data were collected from three focus groups composed of five participants for each group. Each focus group had an interview for two and a half hours on the average. The main question was "What is your perception on the roles of health teachers in elementary schools?" Qualitative data from transcribed notes and field notes were analyzed using qualitative content analysis. Results: Five main roles were identified from the participants. The participants perceived themselves as 'an expert of health education in school and community', 'a health service provider for school members', 'a health guardian for school members, the coordinator of healthcare related works in school, and the leader of school health. Conclusion: The participants have multiple role identities, which are very important for health management of school members. And the roles such as an expert of health education and a leader for school health are recently emphasized. The findings of this study can provide useful information to design orientation programs for newly appointed health teachers and continuing education programs for enhancing role performance of health teachers in elementary schools.

  • The naval combat system is a distributed system in which various subsystems are integrated and operated together. The integrated management system(IMS) is a software system for systematically and consistently managing the application software which control and operate various devices in such a combat system. Since the malfunction or failure of such an IMS can disable the entire combat system, the IMS is more important than other application software of the combat system. In this paper, we propose a method to guarantee the stable and correct operation of the combat system. To this end, we propose a redundancy scheme composed of one leader and several followers so as to tolerate the failure situation of the IMS. We also propose a leader selection algorithm to select a new leader when the leader fails and can no longer perform its role. To verify the validity of the study, we verify the fault tolerance behavior of the system and the accuracy of the leader selection algorithm.

  • This paper describes a monocular vision-based formation flight technology using two fixed wing unmanned aerial vehicles. To measuring relative position and attitude of a leader aircraft, a monocular camera installed in the front of the follower aircraft captures an image of the leader, and position and attitude are measured from the image using the KLT feature point tracker and POSIT algorithm. To verify the feasibility of this vision processing algorithm, a field test was performed using two light sports aircraft, and our experimental results show that the proposed monocular vision-based measurement algorithm is feasible. Performance verification for the proposed formation flight technology was carried out using the X-Plane flight simulator. The formation flight simulation system consists of two PCs playing the role of leader and follower. When the leader flies by the command of user, the follower aircraft tracks the leader by designed guidance and a PI control law, and all the information about leader was measured using monocular vision. This simulation shows that guidance using relative attitude information tracks the leader aircraft better than not using attitude information. This simulation shows absolute average errors for the relative position as follows: X-axis: 2.88 m, Y-axis: 2.09 m, and Z-axis: 0.44 m.

  • According to shift of the political focus from agricultural productivity to social development, it has been increased importance of local leader in rural society. Especially rural women leader's role has been increased not only in agricultural business but also in social activity of locality. Although a lot of leadership study related to rural community development, it has been very scarcely study about leader's action in pattern or doing in style based on psychological scale. Therefore this a kind of pilot study on that. For this data, it was gathered from 24 female farmer leaders of a federation group in 2005. In this study, to define the action in pattern or doing in style of leader, it was adopted to Ozasz Yoshihisa's scale which is consisted of 40 items into 8 types. From analysis of female farmer leader's action in pattern or doing in style, most of them were belong to volunteer type, generalist type, farmer type. This menas most of them were head toward maintenance of the present status, keeping one's balance, adaptation oneself to new environment, or acceptance the logic of events, not trying to innovate. But it was not clear that any variable has a relation in the action in pattern or the doing in style, for definition of variables, it should be more detailed study.
