It is quite sure that e-commerce through internet has significant impacts on consumer behavior and marketing activities as well. In this context, the concept of 'Internet Community' has been emerged and highlighted in consumer marketing. Internet community means social relationships and linkages which can be established through continuous and iterative internet-mediated communications among people with homogeneous interests and concerns. It has been a current trend to exchange product information among consumers by forming internet communities, which would affect sales performance directly or indirectly. It, therefore, is necessary to study the community's behavior and its impact on its marketing performance. This article focuses on the following points : ① the structural concept and factors of forming traditional consumer community and internet community : ② the role of trust and commitment as mediating variables between the internet community formation and marketing performance : ③ the performance and implications of the internet community on marketing.

This paper presents a Case-Sort method to solve the unit commitment problem using database in electric power systems. The formulation of the unit commitment nay be described as nonlinear mixed integer programming. However, it is hard to optimize a problem with discrete and continuous variables in a large-scale system at the same time. The Case-Sort method is based on the unit［MW］generation cost considered drive hour. Then, this paper shows effectiveness and economical efficiency of the proposed algorithm.

Today, environments of healthcare and hospital organizations are changing very rapidly. In response to these rapid and uncontrollable changes, organizational members should be required to be empowered, because empowerment makes feelings of powerlessness and frustration reduce and leads to work performance such as Job satisfaction and Organizational commitment. The term 'Empowerment' is frequently used in recent, but there is a lack of study. In nursing administration, studies are also few. Empowerment is defined here as a cognitive, continuous and active process which empower intrinsic work motivation to members. This study takes empowerment as a construct composed of four factors-meaning, competence, self-determination, impact. 1. The purpose is to analyze the relationship of empowerment with job - satisfaction and organizational commitment perceived by nurses. 2. The method : Data were collected from 334 nurses in 2-hospital and gathered during the period 20days from September 11 to September 30, 2000 and ANOVA, Pearson's correlaton etc are conducted for this study. 3. The results were as follows: 1) In characteristics of subjects, age and the period of duty were significantly different in empowerment (p<0.001). Educational background, marriage and motivation to be nurse were different in empowerment(p<0.05). 2) Empowerment degree perceived by nurses was 55.52. 3) Empowerment was related with job satisfaction (p<0.001) but was not related with organizational commitment. 4. Conclusion : The above result was different from other empowerment studys which empowerment is related with job satisfaction and organizational commitment. The study on empowerment is important in the aspect of strategies for increasement of work performance. For the proper tool in nursing practice, we study empowerment in various aspects and the further studys for the relationship of empowerment with organizational commitment are needed.

The purpose of this study was to identify the relationships among organizational commitment, job satisfaction, and learning organization culture. This study was conducted in five sub-organizations of one Korean conglomerate company. One thousand employees were randomly and proportionately selected, with 669 useable cases obtained, for a response rate of 67%. The organizational commitment instrument used from the "affective, continuance, and normative commitment" scale (ACNCS) of Allen and Meyer (1990). The "Dimensions of Learning Organization Questionnaire" of Watkins and Marsick (1997) was used to measure learning organization culture. The short form MSQ (Minnesota Satisfaction Questionnaire), developed by Weiss, Dawis, England, and Lofquist (1967), was the third instrument used. Descriptive statistics, correlational statistics, and inferential statistics (ANOVA and t-tests) were used. Organizational commitment (except for continuance) is moderately and positively related to job satisfaction and moderately and positively related to learning organization culture. In addition, learning organization culture is weakly to moderately and positively related to job satisfaction. No differences by age were found. Four-year college graduates are more likely to have higher creating continuous learning opportunities in learning organization culture than graduate school degree holders. Males are likely to have higher affective and continuance organizational commitment than females. Employees working in R&D, Engineering, and Manufacturing (REM) are likely to have higher continuance organizational commitment than do other types of jobs. Employees are more likely to have higher learning organization culture and job satisfaction than assistant managers. Assistant managers have higher continuance organizational commitment than managers. Managers generally have higher organizational commitment, learning organization culture, job satisfaction than assistant managers. They also have higher learning organization culture than employees. Employees who had worked for less than four years in their current job and organization have higher promoting inquiry and dialogue in learning organization culture than those who have worked for ten years or more. Employees in the insurance organization have higher affective organizational commitment, learning organization culture, and job satisfaction than those of the other organizations. Finally, employees of the electronic company have higher continuance organizational commitment in learning organization culture than those of other companies. In summary, this research enables CEOs and HRD and HRM practitioners to view organizational commitment, learning organization culture, and job satisfaction as important variables in exploring diverse ranges of topics related to the workplace. And then, they can diversely apply their management, interventions and practices to fit these diverse characteristics.

This paper presents a new approach for thermal unit commitment (UC) using a differential evolution (DE) algorithm. DE is an effective, robust, and simple global optimization algorithm which only has a few control parameters and has been successfully applied to a wide range of optimization problems. However, the standard DE cannot be applied to binary optimization problems such as UC problems since it is restricted to continuous-valued spaces. This paper proposes binary differential evolution (BDE), which enables the DE to operate in binary spaces and applies the proposed BDE to UC problems. Furthermore, this paper includes heuristic-based constraint treatment techniques to deal with the minimum up/down time and spinning reserve constraints in UC problems. Since excessive spinning reserves can incur high operation costs, the unit de-commitment strategy is also introduced to improve the solution quality. To demonstrate the performance of the proposed BDE, it is applied to largescale power systems of up to 100-units with a 24-hour demand horizon.

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.
