This study first presents the characteristics of emerging leadership researches by theoretically analyzing the studies related to leadership since the Millenium. The first finding is that most of leadership researches shared same if not similar aspects of transformational leadership. Secondly, much of leadership researches centered around horizonally expanded shared/distributed leadership. Thus, this researches analyzed the effectiveness of the shared/distributed leadership theory based on previous researches and found shared/distributed leadership has positive impact on member's recognized performance and innovative behavior. However, in competition-oriented culture, shared/distributed leadership did not control recognized performance of its members. This implies the demand for shared/distributed leadership is necessary today and research on the matter will expanded globally but, the results may differ according to the cultural value of the company.

The purpose of this study is to identify the relationship between the employees' perception of organizational justice and their prosocial behaviors, focusing on the moderating effect of employees' individualism and collectivism. The survey has been conducted for 200 participants working in Korean companies. The results show that the perception of organizational justice is positively related with their prosocial behaviors. Also, employees' individualism and collectivism is significantly related with their prosocial behaviors. Specifically, individuals who are more collectivistic or less individualistic performed more prosocial behaviors than those who are less collectivistic or more individualistic. Finally, employees' individualism/collectivism has moderated the relationship between the perception of organizational justice and prosocial behaviors. When employees have strong sense of collectivism, they performed prosocial behaviors consistently regardless of the perception of organizational justice. That is, even though they perceive organizational justice as low, they perform prosocial behaviors in some degree. However, when employees have strong sense of individualism, their prosocial behaviors have been significantly determined by the perception of organizational justice. That is, when they perceive organizational justice as low, they rarely performed prosocial behaviors. But, as they perceive more organizational justice, their prosocial behaviors have been dramatically increased. The implication of those results and future research questions have been discussed.

최근 조직 내 정보시스템이 제공하는 지식과 정보에 대한 공유와 교환이 더 이상 성공적이라고 판단되지 않음에 따라 그 대안으로써 가상공동체(Virtual Community)가 주목받고 있다. 그러나, 가상공동체에서 살아있는 지식과 정보의 공유를 위해서는 공동체 안의 구성원인 리더와 구성원(팔로워) 들의 상호작용을 통한 몰입이 매우 중요하다는 인식이 확산되었다. 그러나, 이러한 몰입에 영향을 주는 리더-구성원 간의 영향관계는 충분히 연구된 바 없다. 이에 본 연구는 가상공동체에서 리더의 리더십 스타일과 팔로워의 특성 그리고 이들 간의 동기와 신뢰가 가상공동체의 몰입에 미치는 인과관계에 대해 분석하고자 하였다. '지각된 리더의 배려'로 측정된 '서번트 리더십'과 '지각된 리더의 조직지향'을 통해 측정된 '변혁적 리더십'이 구성원의 팔로워십과 동기, 리더와 조직에 대한 신뢰에 어떠한 영향을 미치는지 460명의 가상공동체 구성원을 통해 실증적으로 분석하였다. 분석결과 서번트 리더십과 구성원의 팔로워십 특성이 구성원의 몰입에 있어서 중요한 역할을 수행함을 알 수 있었다.

사람의 지문은 그 인식성능과 종생불변성 및 만인부동성으로 인하여 신원인증을 위한 생채인식에서 가장 많이 이용되고 있다. 최근에는 지문인식의 신뢰성에 더하여, 그 인증속도가 지문인식을 각종 보안 어플리케이션에 응용하는데 있어서 매우 중요한 요소로 부각되고 있다. 본 논문에서는 생체면역계에서의 '자기-비자기' 구별과정에 착안한 빠르고 신뢰성 있는 지문인식 알고리즘을 제안한다. 제안한 매칭알고리즘은 지문영상으로부터 추출된 특징점과 방향성분에 기반하여 만들어지는 자기공간(self-space)에 기반하여 이루어지는 1차 매칭과, 특징점의 기하학적 구조에 의하여 구성되는 로컬구조(local structure)에 의하여 구성되는 로컬구조에 의해 수행되는 2차 매칭의 두 단계로 구성되어 인식의 신뢰성을 유지하면서 인증속도를 향상시켰다.

This study aims to explore students' epistemic practices and considerations, which are explained as underlying epistemic thoughts that guide their epistemic practices, during argumentation in science classrooms. We also investigated how collaborative reflection facilitated the development of such epistemic considerations. Two seventh-grade classes participated in this study by engaging in argumentation activities and collaborative reflection after classes. A group with students' change in epistemic aspects and the influence of collaborative reflection clearly revealed from their practices was chosen as a focus group. We recorded their class discussions and collaborative reflections with the researchers. Transcriptions of the recordings and checklists we collected during the collaborative reflections were used for analysis. Results showed evident changes in the students' epistemic considerations and practices and four factors facilitating such developments were identified. First, the researcher facilitating the students to recognize each other as collaborators during collaborative reflection led development of epistemic considerations on "audience using the knowledge products." Second, the collaborative reflection facilitated construction of context for peer interactions where the students encouraged each other to participate in the discussion, resulting in the development of other students' epistemic considerations on "justifications in knowledge products." Third, the items provided on the checklists explicitly delineated expectations on their practices in argumentation, also facilitating development of epistemic considerations. Lastly, the students' imitation of the researcher's pattern of discourse facilitated construction of causal explanation and development of epistemic considerations on "nature of the knowledge products." This study will contribute to the construction of strategies that develop students' epistemic considerations and productive epistemic practices in argumentation.

The purpose of this study is to explore and analyze what has changed in Seoul National University (SNU) since its incorporation, focusing on the perceptions and experiences of its internal members. To this end, semi-structured interviews were conducted with members of SNU, professors, staff, and students. The interview results were presented by categorizing them into changes in the overall evaluation of the incorporation, positive and negative changes, education, research, social contribution, and operating system. Overall, with regard to the changes after incorporation, the members of SNU showed a common perception that it was difficult to feel the change or that there was little change. As for positive changes, they mentioned the expansion of university finances, increased autonomy in operation, and improved responsiveness to environmental changes. As for negative changes, they mentioned the ambiguity of SNU's legal status, and the excessive increase of direct and aggressive influence from outside. In the last part, the main findings were summarized and their meaning and implications were discussed.

Previous researches of organizational citizenship behavior have been focused mainly on organizations, and there have been only a few studies on the organizational citizenship behavior of nonprofit organizations. In particular, few empirical studies have been made on the relations among variables affecting the organizational citizenship behavior of profit and nonprofit organizations. Thus, this study attempted comparative analysis. According to the result of the analysis, in profit organizations, the fairness of procedure, emotional commitment and continuous commitment had a significant effect on organizational citizenship behavior, as well as the fairness of distribution and perception of organizational support. In nonprofit organizations, on the contrary, the fairness of distribution, the fairness of procedure, and perception of organizational support were insignificant, and only emotional commitment and continuous commitment had a significant effect on organizational citizenship behavior. This study is meaningful in that it comparatively analyzed the effects of organization members' perception of fairness on organizational citizenship behavior in profit and nonprofit organizations, and its outcome may be utilized as a reference in future researches but it has a problem in external validity that poses a limitation in its generalization.
