본 연구는 먼저, 새천년 이후의 리더십 관련 연구들을 이론적으로 분석하여 현대리더십 이론 연구의 두 가지 특징을 제시하였다. 첫째는 대부분의 이론들이 변혁적리더십 이론과의 중복성이 높다는 점이고, 둘째는 공유/분산적리더십을 중심으로 한 수평적 리더십 연구의 발전이다. 다음으로, 본 연구에서는 공유/분산적리더십 이론의 효과성을 선행연구를 기초로 분석하고, 공유/분산적리더십이 구성원의 성과인식과 팀 혁신행동에 미치는 영향을 실증분석 하였다. 그 결과, 공유/분산적리더십이 구성원의 성과인식과 팀 혁신행동에 유의적 영향을 미친다는 것을 검증하였다. 그러나 경쟁지향문화의 조절효과 검증에서는 공유/분산적리더십과 구성원의 성과인식 사이에 경쟁지향문화의 조절효과가 검증되지 않았다. 그것은 한국기업의 경우, 경쟁지향문화 속에서는 공유/분산적 리더십의 효과가 구성원의 성과인식을 조절하지 못한다는 것이다. 기업의 문화적 가치에 따라 그 성과에는 차이가 날 수 있다는 점을 시사한다.

Innovation becomes norm rather than exception in today's business, and accordingly firms are working on how to make their employees to work smarter using information systems and technologies. Smart work demands virtual collaboration and cooperation among team members in different places and different time. Sharing of knowledge among team members in these innovative activities are critical in every sense for the successful performance. This study explores the antecedents of knowledge sharing among team members in team-based innovation activities. Five factors (pleasure of knowledge sharing, self-efficacy, management support, rewards, and system usage) are identified through extant review of literature and an instrument is adopted and validated from previous studies. The instrument is adminitered against 138 individuals in and across 54 teams in a telecommunication firm. Except self efficacy, all the paths in the proposed research model is confirmed with different levels of relational coefficients towards the levels of knowledge sharing and innovation activities in teams. Surprisingly, findings indicate that intrinsic pleasure of sharing is most critical than management support, organizational rewards or system usage. This study fills the research gap in team management. Findings provide important implications for managing teams in coming virtual and smart environment.

Purpose: The purpose of this research is, by investigating organizational characteristics, types of nursing organizational culture and team effectiveness in ICU, to ascertain the type of nursing organizational culture and the organizational characteristic that can improve the team effectiveness. Method: The research targeted 427 nurses from 33 ICUs of 14 general hospitals which have more than 250 beds and the data were gathered by using self-report questionnaires from April 10, 2003 to April 24, 2003. For this research, the following tools were used; the tool for measuring organizational characteristics and organizational cultures and the tool for measuring team effectiveness. Result: The most significant nursing organizational characteristic in ICU is the centralization. The organizational culture in ICU is generally rank-oriented culture. There was a significant difference (p<.01) in four types of organizational cultures; relation-oriented, innovation-oriented, rank-oriented and task-oriented. Verifying influence power of organizational cultures upon team effectiveness of ICU, relation-oriented culture had 49.2% of an influence upon team effectiveness, innovation- oriented and relation-oriented culture had 60.4% of an influence, and rank-oriented, innovation-oriented and relation-oriented culture had 61.2% of an influence. The organizational culture profiles according to the types of nursing organizational cultures in 33 ICUs were found by a cluster analysis. They were classified into five culture profiles; strong balance culture profile, weak balance culture profile, innovation-oriented and task-oriened culture profile, strong relation culture profile and strong rank culture profile(p<0.5). According to me organizational culture profiles, a significant difference of team effectivenesses(coworker satisfaction, team performance perception, team satisfaction and team commitment) was found(p<.01). The strong balance culture profile had the best team effectivenesses. Conclusion: For nursing culture management, a nursing administrator should identify the relevant nursing organizational culture at first by utilizing an innovative team-leader. After identifying the organizational culture, the administrator should make strategic plans and practices that can distinguish good organizational cultures to be expanded from ones to be sublated so that a strong balance culture can be developed.

Athletic products must meet the needs of athletes and the demands imposed by sports through innovative design. These needs of athletes and requirements of sports are performance, protection and comfort related. In depth knowledge of anatomy and physiology, etiology of commonly reported injuries, and lower extremity mechanics form the basis of product creation/engineering. Game analysis which entails time and frequency surveys of the skills performed during a game, interviews with athletes and coaches, and discussions with medical staffs are used to identify the skills that are critical to the needs of athletes. In lab full biomechanical analyses of these skills and/or physiological responses of the athletes lead to clear functional criterions that serve as guidelines to be met by the design team. The concepts created by the design team are in turns subjected to the same battery of biomechanical analyses. The learning gathered through this pluridisciplinary process is used to further evolve design concepts. The evolution-testing loop is repeated until biomechanical and/or physiological, mechanical and perceptual tests indicate that the design concept meets the established functional design criterions. At that time, the design concepts is ready for manufacturing research and development. Additional biomechanical and physical tests are performed through that phase to confirm that the manufacturing processes preserve the functionality of the design concept. Durability and long term performance of production samples are evaluated through a final three month long weartest program. A rigorous research/testing program is crucial to create and engineer sport products that meet the performance, protection.
