Team decision making is a collective behavior that needs to be understood by considering properties belonging to team and individual member domains together. This paper introduces a conceptual model called "Dual-Level(DL)" model that describes a team decision-making process in terms of team level, member level, and the relationship between them. The team-level view explains the decision-making process by considering the team as a wholeand divides the process into three stages: Problem Conceptualization, Alternative Generation, and Selection. The member-level view describes what happens to individual members when they go through the group process and splits it into the five phases: Individual Cognitive Mapping, Problem Decomposition, Subproblem Session, Subproblem Integration, and Team Decision. The DL model works as a theoretical framework to explore team decision making by using a set of computational models of team design and team members. In practice, the conceptual framework is used to build a computational model of decision making team, called "Team-Soar."

From a cognitive perspective, this study investigates the role of emergent leaders in developing team cognition and affecting team performance. With application of the cognitive complexity theory, this study hypothesizes that emergent leaders' cognitive complexity will be positively associated with team cognitive complexity, and that team cognitive complexity will be positively associated with team performance. In addition, team cognitive complexity is hypothesized to mediate the effect of the cognitive complexity of emergent leaders on team performance. To test the research hypotheses, data were obtained from 100 teams comprising a total of 339 undergraduate students who participated in a business simulation game. The findings of this study suggests that the cognitive complexity of emergent leaders is a significant predictor of team cognitive complexity, and that team cognitive complexity is positively related to team performance. Moreover, team cognitive complexity significantly mediates the effect of emergent leaders' cognitive complexity and team performance.

급격한 환경변화에 속에서 창의성이 조직 생존을 위한 경쟁우위 요인으로 강조된 이 후, 많은 학자들은 어떻게 하면 창의성을 향상시킬 수 있는지에 대해 관심을 가져왔다. 수많은 조직들이 효율적인 업무처리를 위해 팀 제를 도입하고 있는 현 상황에서 팀 창의성에 대한 관심 역시 증가하는 추세이다. 본 논문에서는 팀 창의성에 대한 이해를 목표로 팀 학습목표 지향성을 선행요인으로 고려한다. 특히, 팀 학습목표 지향성과 팀 창의성 사이의 관계를 설명하는 서로 다른 팀 프로세스(예, 팀 성찰, 팀 효능감, 긍정적 집단 정서 분위기(PGAT: Positive Group Affective Tone, 이하 PGAT))를 밝히는데 목적을 둔다. 본 연구의 분석 자료를 수집하기 위해 서울소재의 한 경영대학에서 개설하는 세 개의 경영학 전공 강좌의 수강생 187명(57개 팀)을 대상으로 설문조사를 실시하였으며, 위계적 회귀분석을 방법을 사용하여 자료를 분석하였다. 분석 결과, 팀 학습목표 지향성은 팀 창의성과 정(+)적으로 관련하는 것으로 나타났으며, 팀 성찰과 팀 효능감을 정(+)적으로 예측하였다. 또한, 팀 성찰과 팀 효능감은 팀 창의적 성과를 유의미하게 예측하였으며, 동시에 팀 학습목표 목표 지향성과 팀 창의성 사이를 매개하는 사실을 확인할 수 있었다. 하지만, 예측과 달리 PGAT는 팀 학습목표 지향성과 팀 창의성과는 통계적으로 관련성이 없는 것으로 나타났다. 이와 같은 본 연구 결과는 다양한 이론적, 실무적 시사점을 가진다.

Team activities in engineering curriculum play the major role in nourishing students with problem-solving and team-working capabilities. Educators endeavor to guide students to achieve success experiences through team activities. The sense of success depends on how the students think and feel about team activities. In this study, we investigated the students thoughts on team activity in various aspects. We provided freshmen and juniors with a set of questionnaire and gathered answers, from which we tried to elicit implication that we may apply for coaching their team activities. The analysis result shows that the perception level of freshmen on team activities is less mature in a sense that the freshmen's view is more neutral than that of juniors. Regardless of the grade, they show that they put more emphasis on the team atmosphere than on the team performance. Especially the freshmen are more sensitive to the relationship between the team members than the juniors. The juniors concern more about whether they prepare well enough for the team activities or not. Both of the grades prefer self-regulation in team formation and think the leadership is essential in performing team activities. However, they both hesitate to take a role as a leader. We expect the research result will provide novel ideas for coaching students to obtain valuable experiences on team activities.

A new type of diffractive spatial optical modulators, named SOM, has been developed by Samsung Electro-Mechanics for projection display and other applications. A laser display in full HD format $(1920{\times}1080)$ was successfully demonstrated by using prototype projection engines having SOM devices, signal processing circuits, and projection optics.

This study investigated the factors that facilitate knowledge creation of team with the aspect of knowledge management. We considered two characteristics which are team members' psychological characteristics (achievement needs and conflict emotion) and knowledge network characteristics among team members (internal cohesion and external bridging) and verified the relationship between these characteristics and team performance. Furthermore, we examined whether these characteristics have a different effect on team performance according to the mastery climate. This study performed a survey targeting team members in knowledge based firms and 376 final surveys to be used as a sample in this study. The result showed that team members' psychological characteristics and knowledge network characteristics among Team members have an influence on team performance significantly. In addition, the master climate moderated the relationship between team members' psychological characteristics and team performance.

The objective of this paper is to show how team study can be advanced with the aid of a current computer technology, that is distributed Artificial Intelligence(DAI). Studying distributed problem solving by using groups of artificial agents, DAI can provide important ideas and techniques for the study of team behaviors like team decision making. To demonstrate the usefulness of DAI models as team research tools, a DAI model called 'Team-Soar' was built and a simulation experiment done with the model was introduced, Here, Team-Soar models a naval command and control team consisting of four members whose mission was to identify the threat level of aircraft. The simulation experiment was performed to examine the relationships of team decision scheme and member incompetence with team performance. Generally, the results of the Team-Soar simulation met expectations and confirmed previous findings in the literature. For example, the results support the existence of main and interaction effects of team decision scheme and member competence on team performance. Certain results of the Team-Soar simulation provide new insights about team decision making, which can be tested against human subjects or empirical data.

Carbon nanotube emitters, prepared by screen printing, have demonstrated a great potential towards low-cost, largearea field emission displays. Carbon nanotube paste, essential to the screen printing technology, was formulated to exhibit low threshold electric fields as well as an emission uniformity over a large area. Two different types of triode structures, normal gate and undergate, have been investigated, leading us to the optimal structure designing. These carbon nanotube FEDs demonstrated color separation and high brightness over 300 $cd/m^2$ at a video-speed operation of moving images. Our recent developments are discussed in details.

The purpose of this study was to analyze the current status of team learning in engineering education. For this, literature review and survey were used. The survey was conducted with 16 professors and 627 students in engineering college. Based on the results, team should be organized in consideration of various characteristics and competencies for effective team learning activities in engineering education. And in the team learning operations, it is necessary to make the conditions for students to immerse in team learning through the activation of communication of team members, tightening management of free riding in team learning, and optimizing team learning period. It is necessary to use the team learning evaluation method in harmony with the team, individual and peer evaluation.
