I. Background and Purpose Health Indicator system and measurement of health status are an important fields in national health fields. This study reviewed the overall concepts of health and health indicators, health indicator system. The purposes of this study are to build the conceptual health framework, and suggest a health indicator system, in order to correspond to the situation of national health and the demand of International organizations. II. Scope and Contents The scope of this study ; - Review of tile conceptual health framework, health indicators, and health Indicator system - Selection and development of tile new individual health indicators - Suggestion of tile revised health indicator system III. Results of Study This study intented to build the conceptual and framework of national health and provide the measurement tools of health status. This study developed the health indicator system through the conceptual and hierarchial approach to national health. The health indicator system contains 6 concern: areas and each sub-areas. The major concern areas are health state and behavior, deathㆍdiseaseㆍdisability, health care utilization, health resources, health expenditure and finance, other affecting factors on health. This health indicator system is corresponding to the situation of health status patterns and the demand of international organizations. And this health indicator system is considering the present health data production system and the availability of health data.

Artificial neural network (ANN) is known to identify relationships even when some of the input data are very complex, ill-defined and ill-structured. One of the advantages in ANN is that it can discriminate the linearly inseparable data. This study presents an application of ANN to classify and predict the symptomatic status of HIV/AIDS patients. Even though ANN techniques have been applied to a variety of areas, this study has a substantial contribution to the HIV/AIDS care and prevention planning area. ANN model in classifying both the HIV and AIDS status of HIV/AIDS patients is developed and analyzed. The diagnostic accuracy of the ANN in classifying both the HIV status and AIDS status of HIV/AIDS status is evaluated. Several different ANN topologies are applied to AIDS Cost and Services Utilization Survey (ACSUS) datasets in order to demonstrate the model\`s capability. If ANN design models are different, it would be interesting to see what influence would have on classification of HIV/AIDS-related persons.

The purpose of this study was to investigate factors affecting consumer's housing tenure status by various household's characteristics. This study used 1997 KHPS(Korea Household Panel Study) by Daewoo Economic Research Institute and used 1,977 households for the analysis. The results of this research were summarized as follows; 1. There were major differences in household's characteristics by consumer's housing tenure status, except for the household's monthly income and savings. 2. Factors affecting consumer's choice of ‘owning’ a housing and taking a ‘chonsei’ system were very similar, but they affected in the opposite direction. 3. Factors affecting consumer's choice of taking a ‘chonsei’ system and ‘renting’ a house were much more similar, and they affected in the same direction. This study can be useful in developing housing service and design, and housing policy by consumer's choice of housing tenure status.

In this study, physiological status of locomotive engineers were measured through EEG, ECG, EDA, PPG and respiration signals from 6 subjects to evaluate their arousal status during train operating. Existence of tunnels and mechanical vibration of train using 3-axes acceleration sensors were recorded simultaneously and were correlated with operator's physiological status. As the result of the analyzed subjects' physiological signals, mean SCR was increased in the section where more body movement is required. The RR interval was decreased before and after train stop due to the higher level of mental tension. The intensity of beta wave of EEG was found to be higher before and after train stop and tunnel section due to the increased mental arousal and tension. Therefore, it is expected that the outcomes of the physiological signals explored in this study can be utilized as the quantitative assessment methods for the arousal status to be used for sleepiness prevention system for vehicles operators which can greatly contribute to public transportation system safety.

This thesis is to research for analysis of ISO 9000 Quality Management System application status of small & medium-sized Industrial Companies. For this research, 10 companies certified by ISO 9000 standard were selected. By using an evaluation method and a software for analysis of application, this thesis compared, analyzed and evaluated the application status before and after certificate of ISO 9000, and identified the performance and difficulty of QMS application, and then proposed improvement methodology for ISO 9000 effective application.

As the role of robots expands, flexible task planning methods are attracting attention from various domains. Many task planning frameworks are introduced to efficiently work in a wide range of areas. In order to work well in a broad region with multiple robots, various communication conditions should be controlled by task planning frameworks. However, few methods are proposed. In this paper, we propose mission planning methods according to the communication status of robots. The proposed method was verified through experiments assuming different communication states with a multi-robot system.

A certificate that is issued by the certification authority can be revoked within the period of validity by various reasons such as the loss of private key, disqualification or the change in key. Therefore, the certificate status verification must precede prior to use Currently, the CRL or the OCSP methods are used in most cases. But the CRL system can't guarantee the present status of the certificate, and the OCSP generates heavy network traffic by checking or requesting certificate status in real-time using high-capacity messages. In this paper, we propose a system that requests the certificate verification by creating VDN for user identity information. Through this system, the certification authority will be able to guarantee the certificate's status in real-time, and solve the problem of the sewer and network overload by verifying and finding user identity information from VDN, Based on the results, we propose a real-time certificate status verification system which can improve the speed of the verification. We confirmed the improvement in speed by testing and comparing it with the existing methods.

In this paper forest fire status information management system was developed under web environment using web GIS(geographic information system) technology. Though this system, general users can easily retrieval domestic forest fire status information and obtain that in visual way such as maps, graphs, and texts if they have only certain web browsers. Moreover, officials, who have system access authority, can easily control and manage all domestic forest fire status information through input interface, retrieval interface, and out interface of the system. This system can be considered as the first domestic system to manage forest fire status data and service them in visual through user friendly interfaces on web. In order to implement this system, IIS 5.0 of Microsoft is used as web server and Oracle 8i and ASP(active server page) are used for database construction and dynamic web page operation, respectively. Also, ArcGIS IMS(internet map server) of ESRI is used to serve maps by using Java and HTML as system development languages. Not only the domestic tendency of forest fire but also the forest fire status information of certain area and time such as the frequency and the loss can be presented through distribution maps, graphs and tables. Therefore, this system is supposed to play as a important role when the policy relate to domestic forest fire is established. In addition, the self consciousness of people against forest fire can be inspired and the foundation of scientific and systemic forest fire services can be obtained through this system in the future.
