The major goal of this paper is to develop a practically implemental radial basis function (RBF) neural network based multi-user detector (MUD) for direct sequence (DS)-CDMA system. This work is expected to provide an efficient solution for RBF based MUD by quickly setting up the proper number of RBF centers and their locations required in training. The basic idea in this research is to estimate all the possible RBF centers by using supervised ${\kappa-means$ clustering technique, and select the only centers which locate near seemingly decision boundary between centers, and reduce further by grouping the some of centers adjacent each other. Therefore, it reduces the computational burden for finding the proper number of RBF centers and their locations in the existing RBF based MUD, and ultimately, make its implementation practical.

Public research, which requires large computational resources, utilizes the supercomputers of the National Supercomputing Center in the Republic of Korea. The average utilization rate of resources over the past three years reached 80%. Therefore, to ensure the operational stability of this national infrastructure, specialized centers have been established to distribute the computational demand concentrated in the national centers. It is necessary to predict the computational demand accurately to build an appropriate resource scale. Therefore, it is important to estimate the inflow and outflow of computational demand between the national and specialized centers to size the resources required to construct specialized centers. We conducted a logit model analysis using the probabilistic utility theory to derive the preferences of individual users for future supercomputer resources. This analysis shows that the computational demand share of specialized centers is 59.5%, which exceeds the resource utilization plan of existing specialized centers.

Data centers, which implement cloud service, have been faced up with quick growth of energy consumption and low efficiency of energy. 60GHz wireless communication technology, as a new option to data centers, can provide feasible approach to alleviate the problems. Aiming at energy optimization in 60GHz wireless data centers (WDCs), we investigate virtualization technology to assign virtual resources to minimum number of servers, and turn off other servers or adjust them to the state of low power. By comprehensive analysis of wireless data centers, we model virtual network and physical network in WDCs firstly, and propose Virtual Resource Mapping Packing Algorithm (VRMPA) to solve energy management problems. According to VRMPA, we adopt packing algorithm and sort physical resource only once, which improves efficiency of virtual resource allocation. Simulation results show that, under the condition of guaranteeing network load, VPMPA algorithm can achieve better virtual request acceptance rate and higher utilization rate of energy consumption.

Objectives : This study was conducted to review the diffusion process and factors affecting the adoption of the Health Center Information System (HIS). Methods : Data were collected from POSDATA (private company), MOHW, other Ministries and local governments. To specify the date of adoption, supplementary information was collected from 40 health centers. The following three kinds of factors were analyzed. Internal factors included type, size, and innovativeness of health centers. Community factors were composed of population sire, economic status, and level of education. Organizational environmental factors consisted of information score of the municipalities, financial support of the from central government, and the neighborhoodness of innovator health centers. Results : All health centers in the metropolitan cities of Seoul, Gwangju and Jeju adopted the HIS. The laggards were those in the metropolitan cities of Busan (18.8%), Incheon (20.0%) and Daejun (20.0%), and cities with population more than 300,000 (54.8%) and counties with health center hospitals (47.1%). Financially supported rural health centers adopted the HIS more rapidly than those not supported. The factors identified as being statistically significant (p<0.05), from a univariate analysis by Kaplan-Meier method, were: (1) internal factors of the type, size and innovativeness of health centers; (2) community factors of population size and economic status; (3) organizational environmental factors of the central government financial support and the neighborhoodness of innovator health centers. A multivariate analysis, using a Cox proportional hazard method, proved the innovativeness of health centers, central government financial support and the neighborhoodness of innovator health centers, were statistically significant (p<0.05). Conclusions : The innovativeness of health centers, financial support from central government and the neighborhoodness of innovator health centers, rather than community factors related to regional socioeconomic status, affected ffe adoption of the HIS in health centers. Further in-depth studies, modifying the MOHW's strategy to propagate the HIS to the laggard health confers, are recommended.

Information technology will inevitably and profoundly alter every aspect of university life. New information technologies are creating new patterns in the research and teaching, with networks enhancing information sharing and data transmission. The revolution in information technology requires that universities integrate information technology with their traditional missions of teaching, research, and public service. Enhanced mode of information access and changing information-seeking behaviors suggest the need for new library services. New technologies have opened up many new services options for libraries. The nature of and potential for new information services suggest that libraries should become better connected with other campus units. Some of these issues will no doubt be addressed by the a n.0, pplication of new technologies and by building campus information infrastructure. An important element of the needed change for enhancing the library information services is the integration of the libraries and computing centers. Libraries and computing centers deal with the same commodity-information and delivering information. For the sake of scholarship and research, the two must devise an integrated a n.0, pproach to delivering the common commodity. Computing centers have special skills in system development and telecommunications. Libraries have good human interface skills and skills for organizing knowledge. Together they could be a particularly productive team. Noting this, some universities have created new information service units which unify the present-day computing, library and telecommunication functions. Existing models range from true merging to situations where some cooperative activities are being conducted. The purpose of this study is to suggest the direction in developing of information services in academic libraries by examining the changing information environment and trends of integrating libraries and computing centers. This paper inquires into the changing information environment, the impact of imformation technology on universities and libraries, some casses of integration of academic libraries and computing centers, and effects of integration of two and suggests the developing direction of information services in academic libraries.

Scientific documentation is one of the three preconditions for scientific research and its technical application in the industrialization process. To solve the documentation problems on an international level, UNESCO promotes abstracting, standardization of terminology and of scientifc publications, automatic information processing and translating. Moreover, UNESCO has helped to establish since 1950, on the request of interested national governments, 12 documentation centers within the framework of United Nations Technical Assistance Programme by providing experts, fellowships and equipment. Some data on these documentation centers and a comparison of their features should be of interest for all those who wish to set up new documentation centers or to improve already existing ones.

Purpose: To identify the effects on tuberculosis mortality of a tuberculosis control program conducted at 108 community health centers in terms of structure and process. Methods: The dependent variable was tuberculosis mortality, and the independent variables were the structure(type of centers, staff, nurses, doctors, budget) and process(chest X-ray checking, immunization, case detection, health education, patients registering & managing) of the tuberculosis control programs at the community health centers. Data were analyzed using descriptive analysis and stepwise regression analysis. Result: Tuberculosis morality was positively correlated with type of centers(rural area)(p<0.01), but negatively correlated with type of centers(large cities) (p<0.01), (middle cities)(p<0.05), staff FTE(p<0.05), and number of nurses(p<0.05). Regression analysis indicated that type of centers(rural area)($\beta$=0.457) and case detection($\beta$=0.234) had a significant effect on tuberculosis mortality. Conclusion: Ultimately, this study will provide information to improve the effectiveness of tuberculosis control programs in community health centers.

This study was designed to analyze the status of government policy on the computerization of health centers throughout the country and to identify the factors affecting a successful implementation of the information system. As expected, age and commitment of health center director, computer budgets, user training, and technical supports from the information specialists were the important factors influencing the successful implementation of the system. Compared with the urban health centers, fewer rural health centers installed the system perhaps due to lack budgets and the urban-oriented system features. Moreover, the systems were unevenly distributed according to the geographic regions. Some strategies for successful dissemination of the systems were also suggested.
