This study investigates effcts of HMO internal structural arrangements on performance, specially cost reduction measured by hospitalization rate. This study formulates formalization, centralization measured by decision-making participation, differentiation, and coordination as structural factors, considering coordination as an intermediate factor between the rest of structural factors and hospitalization rate. The commonly used HMO types is assumed not effective in explaining performance differences. For the empirical test, I use bootstrap regression analyses with 48 HMOs. The results of the analyses show that HMO types fail to explain differences in hospitalization rate. However, dicision-making participation and differention effectively reduce hospiatalization rate, while frmalization increases hospitalization rate and coordination has nonessential effect on hospitalization rate. And, formalization and decision-making participation positively contribute to achieve coordination in HMO. These findings suggest that the theoretical framework derived from rational-citingency theory of formal organization better explains performance differences of HMOs than HMO types.

The employment of risk management theory in Urban Disaster Management System (UDMS) has become an important trend in recent years. The viewpoint of risk management is mainly a comprehensive risk assessment of various internal and external factors, and a subsequent handling of risks. Through continuous and systematic accumulation and analysis of risk information, disaster prevention and rescue system is established. Taking risk management theory as the foundation, Organization for Economic Cooperation and Development (OECD) has developed a series of UDMS in the mega-cities all over the world. With this system as a common platform, OECD cooperates with different cities to develop disaster prevention and rescue system consisting of vulnerability assessment methods, risk assessment and countermeasures. The paper refers to the urban disaster vulnerability assessment and risk management of OECD and the mega-cities of different advanced and developed countries in the world, and then constructs a preliminarily drafted structure for the vulnerability assessment methods and risk management mechanism in the metropolitan districts of Taiwan.

Recently, Knowledge Management (KM) has been applied to construction industry. Surprising, there is few studies that address the most fundamental problem in KM: people may prefer not to share their knowledge so as to preserve their intellectual or unique values in the organization. Without the premise of each individual's willingness to share knowledge, there will be no valuable input for the IT system and, thus, no knowledge management at all. This paper aims to model the behavioral dynamics of knowledge sharing and to design an incentive system that may facilitate knowledge sharing for construction companies. In this paper, a game-theory based model will be developed, and the framework for designing an incentive system will be proposed according to the model.

This paper was studied on a strategy in rice production under New round system of WTO(World Trade Organization) in Korea. Under enactment of New round system in WTO rice will be opened at the world market and thus rice growers will compete with this marketing system. In this regard, rice industry in Korea would be "a theory of rice triangle" such as high quality, low cost, and environmental friendly system. High quality rice would be obtained through a cultivar, cultivation technology, and quality control(QC) to compete against oversea's dealer. Lower cost in rice production should be concentrated into rapid decrease in rural population and into introducing for young generation. Rice cultivation has been played major role in this peninsula in terms of a preservation of water resource, fresh air and prevention of soil erosion.

As construction projects have been getting larger and more complex, a single individual or organization cannot have complete knowledge or the abilities to handle all matters. Collaborative practices among heterogeneous individuals, which are temporarily congregated to carry out a project, are required in order to accomplish project objectives. These organizational knowledge creation processes of project teams should be understood from the active and dynamic viewpoint of how they create information and knowledge rather than from the passive and static input-process-output sequence. To this end, agent-based modeling and simulation which is built from the ground-up perspective can provide the most appropriate way to systematically investigate them. In this paper, agent-based modeling and simulation as a research method and a medium for representing theory is introduced. To illustrate, an agent-based simulation of the evolution of collaboration in large-scale project teams from a game theory and social network perspective is presented.

Isolation-with-migration (IM) models have become popular for explaining population divergence in the presence of migrations. Bayesian methods are commonly used to estimate IM models, but they are limited to small data analysis or simple model inference. Recently three methods, IMa3, MIST, and AIM, resolved these limitations. Here, we describe the major problems addressed by these three software and compare differences among their inference methods, despite their use of the same standard likelihood function.

The purpose of this study is about theoretical approach to scrutinize contents of spatial information and its communi-cating mechanism for revealing the interrelationship of architectural spaces and design factors in design process. It can be resulted that in architectural problem solving for adequate systemization of architectural spaces in specific conditions, intercommunication between social, psychologi-cal, perceptional aspects is important not so much as creati-ve design.

Nowadays, the wide spectrum of changes have been occurred in library world. It is essential for librarians to improve their professionalization standards to convert these changes into the o n.0, pportunity of growth. The device of improvement of professionalization standards is following: 1. Librarians have to receive formal and informal education and learn to advance in knowledge and skill concerning library affairs continually. 2. Self learning has to be transform into learning organization. 3. Education of Librarianship concentrate mainly in practical and technical study by this time but it is indispensable to develop the theory and philosophy of librarianship.

This case study aims at investigating the factors which make venture firms successful. It analysedthree high-performance venture firms originated from the government-financed rese arch institute, the company and the university on the viewpoint of 'dynamic capability' theory. In this case study, technology integration capability and administrative innovation capability were identified as success factors of the three venture firms. The study also presented the role of the incubating organizations. Although incubating organizations supported technological and managerial resource-building of the entrepreneurs, there was not active interactive-learning between venture firms and incubating organizations after spin-off.

This study introduces and analyzes the data from Directory of Korean NGOs, which was published in 1997 and again in 200, to conduct a quantitative research on the growth of civic organization in South Korea. This paper focus on the information on membership size and founding year which are essential indicators for the growth of organizations. Missing rates on those two indicators are checked to evaluate the quality of data. We examine the changes in membership size between the two time periods, 1996 and 1999. It shows that there is a considerable decrease in the membership size for civic and advocary organizations that are oriented to national issues. It suggests the competition among the organizations over limited resources, which is consistent with an assumption of ecological theory of organization on non-linear growth pattern. Using founding year data from 1945 to 1996, we estimate pseudo growth curves of civic organizations based on logistic growth curve model to discuss different growth patterns of organizations across areas of activities.
