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.

본 연구는 리더의 마키아벨리즘(machiavellianism)과 구성원 이직의도(turnover intention)간의 상관관계를 검증하는데 목적이 있다. 이를 위해 후견지명(hindsight bias)의 매개효과를 통해 연구모델의 전반적인 메커니즘을 규명하고자 하였다. 가설검증을 위하여 다양한 직종의 300인 이상 기업에 근무 중인 직장인 335명을 대상으로 설문을 진행하였다. 연구결과 첫째, 리더의 마키아벨리즘은 구성원 이직의도에 정(+)의 유의미한 영향을 미치는 것으로 나타났다. 둘째, 후견지명은 리더의 마키아벨리즘과 구성원 이직의도 간에 정(+)의 유의미한 매개효과가 있는 것으로 나타났다. 이는 리더의 마키아벨리즘 성향이 높을수록 후견지명을 높게 경험하고 조직의 유효성에 부정적인 영향을 주어 구성원의 이직의도가 높아지는 것으로 추론해 볼 수 있다. 따라서 본 연구는 리더의 마키아벨리즘과 후견지명 및 구성원 이직의도 간의 메커니즘을 검증하여 기존 연구의 내용과 차별적인 관점에서 새로운 시사점을 제시하고 리더의 역할에 대한 향후 연구방향 및 한계점을 제시하였다.

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.

The 4-H camping programs in USA have been providing various resources so that members can achieve their physical, intellectual, social and spiritual potential. The camping programs have been carried out members to participate in programs as responsible citizens in their local, national and international communities. One of the key requirements of successful youth camping was the leadership role of leaders with more conscious and systematic for preparing, equipping, and carrying out programs. This paper was intended to explore the goals of 4-H camping and leaders' role in USA, and give implications to Korean outdoor activities. To perform the 4-H camping effectively, the camping leaders need to focus on the following steps: First of all, they need to recognize the specific purposes and missions of participation in the 4-H camping. Secondly, they should make sense of the site-based teaching skills and its application in the field. Thirdly. they should set up the principles of effective camping strategies and abide by the steps in the process of activities. In addition, they should be qualified to handle the risk management skills, research and survey technology, and environment conservation efforts throughout the camping.
