Generating an action plan and obtaining commitment to achieve it is desired in organizations, but not always achieved. Whatever the reason, there is a room for an improved approach to decision making, so that people can arrive at a common understanding of a problem and commitment to action. Those are the purposes of a Decision Conferencing(DC). A DC, one example of single workstation-based GDSSs, is a two-day session attended by a group of people who attempt to resolve important issues of concern to their organization with the help of group facilitation techniques and decision analytic computer modelling. The interchange of differing perspectives on the issues is encouraged by the facilitator who attends to group processes but does not contribute to the content of discussions. Decision analysis provides a variety of structures for modelling the differing perspectives. Information and value judgements are incorporated in these models, whose results usually reveal new, higher-level perspectives on the issues. Information technology is needed to combine the part of the model and to facilitate on-the-spot replay of results. The experimental case study in this paper shows that how a DC can help a Korea's trading company to develop new, corporate level resource allocation strategies which are based on improved consensus among competing participants.

WiMAX에서 핸드오버를 준비하는 단말은 타겟 기지국을 결정하기 위해 스캐닝 동작을 수행한다. 보다 빠른 타겟 기지국 결정을 위해, 기존의 그룹 스캐닝 기법에서는 인접한 단말들 간에 그룹을 구성하여 분산적으로 후보채널들을 스캔하도록 하였다. 그러나 기존의 그룹 스캐닝은 각 단말이 사용 중인 서비스의 QoS 요구조건이 각기 다른 경우, 각 단말이 후보 채널들을 스캔하는 성능에 차이가 있을 수 있음을 고려하지 않았다. 본 논문에서는 그룹 스캐닝을 수행하는 단말들이 각각의 QoS에 적합한 스캔 스케쥴을 갖도록 하는 QoS 기반의 효율적 그룹 스캔 스케쥴링 기법을 제안한다. 제안된 방법은 서빙 기지국이 단말의 QoS를 고려하여, 초기에 그룹을 형성한 단말들과 나중에 그룹에 참여하는 단말들에게 적절한 후보 기지국들을 스캔하도록 할당하며, 각 단말이 QoS를 저해하지 않으면서 효율적으로 그룹 스캐닝을 수행할 수 있도록 한다. 모의 실험 결과, 제안된 방법은 단일의 그룹 내에서 상대적으로 QoS가 높은 단말로 하여금 상대적으로 적은 채널을 스캔하도록 하며, 각 단말의 QoS를 저해하지 않는 범위 내에서 기존의 그룹 스캐닝 보다 빠르게 타겟 기지국을 결정하도록 한다.

최근에 커뮤니티 컴퓨팅에서 그룹형성과 그룹 의사결정에 관한 이슈가 제기되고 있다. 그러나 기존의 커뮤니티 컴퓨팅 시스템에서는 그룹의 욕구를 인지함에 있어서 임시적인 방법으로 그룹을 형성하지 못하고 있다. 임시적인 방법의 그룹형성은 유비쿼터스 컴퓨팅의 의사결정지원 시스템과 서비스에서 중요한 특성 가운데 하나이다. 따라서 본 연구에서는 유목 커뮤니티 컴퓨팅에서 임시적으로 욕구를 인지하고 그룹을 형성할 수 있는 NAMA-US 에이전트 중심의 다중 에이전트 방법론을 제시하고자 한다. 이 방법론은 어떤 커뮤니티에서 상대적으로 작은 그룹의 복수의 개별 사용자의 그룹의사결정을 지원할 때 다음과 같은 세 가지 특성을 만족하고자 한다. 첫째 임시적인 그룹형성과, 둘째 상황인지 그룹 욕구인지, 그리고 셋째 실내. 외에서 동작 가능한 모바일 장비의 활용이다. RFID 기반의 프로토타입 시스템인 NAMA-US는 본 연구에서 제시하는 이런 개념을 실현시키기 위해 구축되었다.

I have done a case study on group level based-organizational behavior textbooks published in Korea and USA. The objects are 'organizational behavior' by Su Yong Jung and 'organizational behavior' by Im Chang Hee in Korea, and 'organizational behavior' by Schermerhorn, Osborn, Uhl-Bien, & Hunt and 'organizational behavior' by Robbins, & Judge. The goal of this study is to identify the differences of the perspectives on the group level based-organizational behavior between Korean and American textbooks. This research finding shows that it is valid to classify organizational behavior into such categories as group & team, communication, decision making, leadership, power, and conflict & negotiation in the Korean textbooks for the better future study.

The purpose of this research was to analyze the correlation between the Apartment Purchase Price Decision Factor and Amenity decision Factor with cognition of the Consumer. The result are as follows; 1. The correlation coefficient between the Apartment Price Decision Factor and Amenity decision Factor with cognition of the Consumer was 0.587. 2. The ranking of the purchase price factor which it prefers were analyzed orientation > sunlight > view > the rising price expectation > natural environment etc. And the ranking of the amenity were analyzed orientation > natural environment > view > sunlight > noise etc. 3. Consumer group was classified the location, sex, year of ages and unit scale. The rank correlation coefficient of (the significant was below 0.05) sex was 0.617~0.644, year of ages was 0.62~0.771 and unit scale was 0.762~0.852. This research proved the fact that the amenity correlated with the apartment purchase price decision factor, so amenity contained an economic value. And this result will be used in decision-making-process of apartment construction.

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."

This article deals with the multiple alternative proposal of Strategy. when Decision makers meet a very complex and important problems to take a good choice. It might not be easy that we make a decision and accept the decision as an exact result of analysis at a complication and uncertain situation. Although the decision under unpredictable state is many existence and each field is classified to support it. he can not provide exact estimations and be able to specify a result and forecasting. This is the reason why the original research use Statistical Survey method and Visual Decision Making Process(VDMP) to improve decision analysis method. Therefore, Our research suggests that the VDMP utilized in the strategic decision making situation as a group decision adding tool, can be applied in the development of a process vision and implementation plan. as a result, researcher describe step by step the process of VDMP.

Recently a new multi-attribute analysis method is one of the evident areas of important points in the decision support system analysis. The area of decision support system may be broken into three primary area: idea generation, multi-attribute structured analysis method, and the integration of the results of analysis. This research developed an internet/intranet-based solution builder for a three-step decision support system in the view of 1) brainstorming for the idea generation, 2) analytic hierarchy process as a multi-attribute structured analysis method and 3) aggregating logic model to integrate the results of individual analysis. A computer program is developed and demonstrated in internet/intranet-based decision problem. This solution builder provides decision makers a good tool for remote group decision making.

Purpose: Current study aimed at exploring the effects of ambient anger versus sadness on motive type and coping strategy type when consumers make decision. It focused on whether the negative affects of the anger and the sadness differentially induce approach versus avoidance motive at the place of making decision, and also explored the coping strategy differences between the consumers under the anger and those under the sadness, that is, which strategy is more used between problem-focused strategy and affect-focused strategy when they are under each negative affect. Research design, data and methodology: The experimental groups were divided into two types of group such as the anger-felt group and the sadness-felt group. The experiment was performed with the between-subjects design based on the anger and the sadness. Questionnaire data were collected from undergraduate students assigned to each of the anger group and the sadness group operated by the scenario method, and the data were used to verify research hypotheses by t-test. Results: - First, the anger induced the approach motive more rather than the avoidance motive in making decision. Second, to cope the negative affects, consumers under the anger used problem-focused strategy more than affect-focused strategy, while those under the sadness used affect-focused strategy more than problem-focused strategy. Therefore, this article contributes to the theory related to motive and making decision taken place to consumers under ambient negative emotions. Conclusions: Focusing on the results of this study, there could be managerial implications to brand or product marketing managers. Checking which affect consumers previously felt between anger and sadness when they are under negative affects is at issue to the brand or product marketers when they appeal their brand or product to the consumers. The marketers should build and communicate the messages about their product or brand in the respect of the points of showing problem solution or the best way to handle things to appeal the consumers under the anger. And they should develop and communicate the messages about their product or brand emphasizing the aspects of letting consumers' sad feelings out somehow or controlling their emotions to the consumers under sadness.
