Due to the increasing complexity to handle conflicts and interruptions caused by resource failures and rush orders, shop control is obliged to redesign its organization according to the changing demands of the manufacturing control. These demands are leading to the development of decentralization and gradually to their permanent optimization. As a result, a powerful modeling method which can be adapted efficiently is required. The use of agent theory enables specific modeling of the relevant shop planning activities. The planning activities are modeled in a so-called activity modeling through the definition of three classes of agents; Plan Agent, Manufacturing System Agent and Control Agent as well as the description of the cooperative relationship among these agents. On the basis of the activity model the agent-based shop control method is developed which emphasizes the distributed problem-solving and the cooperation with relevant agents.

This paper presents a fuzzy-goal programming(FGP) approach for Bi-Level Linear Multiple Objective Decision Making(BLL-MODM) problem in a large hierarchical decision making and planning organization. The proposed approach combines the attractive features of both fuzzy set theory and goal programming(GP) for MODM problem. The GP problem has been developed by fixing the weights and aspiration levels for generating pareto-optimal(satisfactory) solution at each level for BLL-MODM problem. The higher level decision maker(HLDM) provides the preferred values of decision vector under his control and bounds of his objective function to direct the lower level decision maker(LLDM) to search for his solution in the right direction. Illustrative numerical example is provided to demonstrate the proposed approach.

본 연구는 비영리단체에 기부를 하는 소비자들의 자선충동의 동기가 심리적 성과에 미치는 영향을 탐색적으로 살펴보았다. 이를 위해 본 연구는 자기결정성 이론에 근거한 비영리 단체에 대한 자선충동 동기가 소비자-비영리단체 간의 동일시를 매개변수로 하여 기부충성도에 영향을 미치는 요인임을 제시하였다. 본 연구는 기부자들이 비영리단체에 대한 심리적 측면에서의 자선충동 동기에 관한 연구가 전무한 실정에서 자선모금기관이 재원을 확보할 수 있는 효과적인 마케팅 전략을 구축하는데 기초자료를 제공하며 소비자들의 자선충동 동기에 대해 탐색하는 최초의 연구로서 중요한 의의를 가진다.

Grammatical inference methods are expected to find grammatical structures hidden in biological sequences. One hopes that studies of grammar serve as an appropriate tool for theory formation. Thus, we have developed JSequitur for automatically generating the grammatical structure of biological sequences in an inference framework of string compression algorithms. Our original motivation was to find any grammatical traits of several cancer genes that can be detected by string compression algorithms. Through this research, we could not find any meaningful unique traits of the cancer genes yet, but we could observe some interesting traits in regards to the relationship among gene length, similarity of sequences, the patterns of the generated grammar, and compression rate.

Existing models of knowledge processing do not feature a systemic meaning of knowledge management and ignore the role of leadership and social energy in the knowledge processing system (KPS). This conceptual paper introduces the Leadership Invigorating Flows of Energies, (LIFE) Model as an attempt to remedy that situation and provide a more useful description of the KPS. The LIFE Model highlights the role of emergent leadership and flows of social energies as forces encouraging knowledge creation and dynamic diffusion within an organization through the Knowledge Processing Cycle in eight activities interacting with its social knowledge base in a self-organizing system.

This paper presents an analysis of the Teaching and Learning for a Sustainable Future (TLSF) program, an innovative teacher education and regular professional development by the United Nations Educational, Scientific and Cultural Organization (UNESCO) employing the curriculum analysis framework created by Posner. Using this framework the analyst found that the TLSF design is based on good research in regard to learning, teaching, and assessment now driving efforts to reform environmental teacher education. Ongoing development of the TLSF program in the research setting of an international level permits ever deeper connection with emerging curriculum theory and curriculum practice and allows new linkage as ideas are tested in research classrooms.

This study examined the factors that make Korean companies adopt supply chain management systems. By adding a group of inter-organizational factors, we extended an innovation-theory-based research model to study the information technology adoption. Sixty three questionnaires from 700 leading companies in Korea were collected and analyzed. Independent variables of the research included environmental, organizational, innovation, and relational characteristics. We found that supply chain management systems in Korean companies are at the initial stage of the adoption, in general. This research also found that company's environmental characteristics have insignificant relationship with the adoption of supply chain management systems. In addition, organizational characteristics (the support of top management, the size of organization, and the information technology infrastructure), innovation characteristics of the supply chain, and the power exercised over the supply chain played important roles in adopting supply chain management systems.

The main purpose of this study was to examine the impact of religious participation on the depression of elder adults in USA. Specifically, this study examined how the influence of religious participation varied according to continuity or discontinuity of participation. Data from N=1,658 adults aged 65-90 who were respondents to two waves of the U.S. National survey of Families and Households 1987-1993 were used for these analyses. Depression was measured with a 12-item (of the original 20) modified version of the CES-D (Center for Epidemiological Studies-Depression). Multivariate regression models controlling for several demographic variables were estimated. Some clear evidence was found supporting activity theory and continuity theory That is, participating in a religious organization role at Time 2 but not Time 1 (T1 No - T2 Yes) and being continuously involved in religious organizations both at Time 1 and Time 2 (T1 Yes -T2 Yes) were associated with reduced depression, compared to continuous nonparticipation in religious organizations (71 No -72 No).

For decades, thousands of corporation introduced knowledge management systems to respond knowledge-based society. However, it seems that the systems merely focusing on knowledge accumulation and its sharing have been bounded by many restrictions in terms of new knowledge creation based on the life cycle of knowledge management systems. Moreover, recently, a variety of knowledge management activities regarding organization, systems, and process is emphasized as a strategic asset for a corporation to create core knowledge. Therefore, this study adopted the Csikszentmihalyi's flow theory to investigate the factors affecting knowledge creation and the success factors of knowledge management systems in virtual space. Prior studies argued that flow experience should be a prerequisite for creative knowledge creation. In that vein, this research revealed the causal relationships for flow experience between the determinants of clear goal, immediate feedback, congruence of challenge and skill. Additionally, it empirically examined how flow experience affected the exploratory behavior of knowledge creation.

This Paper examines analytic studies of the evaluation system used for evaluating government-supported R&D Institutes (GSRIs), and designs a new model for analyzing the evaluation system's effectiveness. The analytic models in existing studies use the meta evaluation and balanced scorecard (BSC) models. However, theses studies focused on the structure and elements of the evaluation system for examples, the appropriateness of the elements within the evaluation system and the balance of the evaluation index. Accordingly, the effectiveness of the GSRI evaluation system, that is, the evaluation's influence on GSRI performance improvement was not analyzed. This study uses the institution theory and contingency theory perspectives as related to government organization management to develop an analytical model of GSRI evaluation system effectiveness. The new model proposes an analytical approach for improving the effectiveness of the GSRI evaluation system in an institutionalized environment.
