The level of informaiton provided by most current EIS systems is not above presentation and reporting. To maximize the effect of EIS, we must increase executives' use-rate. To do so, it is important to provide information really required by the user. In a addition, the decision support funcitons should be provided for strategic decision making. In this paper we propose the methodology for adding the analysis and prediciton functions to the EIS that is, for supporting the decision making with the system. Finally, we present a pilot system based on the proposed methodology.

With the development of information technology, knowledge information-oriented and information systems are being rapidly paced. In addition, doctor's needs of the system that assist decision making is gradually increasing. Because the complex process of decision-making should be a lot. We propose a web based system for supporting medical treatment based on Korean medicine ontology. There are three kinds of processes. First, a pattern is decided for patient' symptoms, a formula for the pattern is selected and medicinal materials constituting the formula is added or removed. Second, a formula is decided for patient' symptoms, medicinal materials constituting the formula is added or removed. Third, a Treat method is decided for patient' symptoms, medicinal materials constituting the formula is added or removed. We have designed and implemented the clinical decision support system that supports flexible processes and necessary information and functions. The system shows the appropriate form of ontology knowledge as interrelated and provide analysis and processing, does not show simply search. The system is one of the systems utilizing ontology and a web based system that can be used in anywhere. Therefore, This system Will be useful as for doctors to make decision.

The rapidly changing environment have forced organizations to improve systems thinking capability to coordinate diverse activities across cross-functional business areas necessarily involving group decision-making processes. Although many approaches have been introduced to enable the collaborative processes of group decision-making, they often lack features supporting the dynamic complexity issues. The study proposes system dynamics modeling based on simulation techniques to improve systems thinking capability in group decision-making context.

A recent High Court's decision regarding the withdrawal of life supporting medical treatment (artificial ventilator) from an elderly female patient in the terminal stage has opened up a new era of the "euthanasia dispute" in Korea. With this decision, the legitimate withdrawal of life supporting treatment became possible under certain conditions and the Korean Medical Association is working toward the establishment of practical guidelines for the terminal-stage patients. However, there are still very few debates on the cases of pediatric patients in the terminal stage or suffering from fatal diseases. For pediatric patients, the core principle of autonomy and following procedure of "advance directives" are hardly kept due to the immaturity of the patients themselves. Decisions for their lives usually are in the hands of the parents, which may often bring out tragic disputes around "child abuse", especially in Korea where parents have exclusive control of the destiny of their children. Some developed countries such as the U.S.A., the U.K. and Canada have already established guidelines or a legal framework for ensuring the rights of the healthcare system regarding children suffering from severe illness, permitting the withdrawal of Life supporting medical treatment (LSMT) in very specific conditions when the quality of life of the children is severely threatened. For the protection of the welfare and interest of the children, we should discuss this issue and develop guidelines for the daily practice of pediatricians.

The purpose of this study is to investigate and to develop a decision support system for supporting the outworn facility replacement analysis in shipbuilding. This paper also provides an information system which can be effectively applied to various criteria in decision making. The modelbase of decision support system uses the concepts of the analytic hierarchy process along with an appropriate scoring methods. The AHP represents an improvement over other well-known scoring approaches since the criteria weights of priorities established by the AHP are not based on arbitrary scales, but use a ratio scale for human judgements. The proposed methodology in this research enables the decision maker to evaluate the investment alternatives based on qualitative data and quantitative data in a systematic way.

In near future, more congested and dangerous marine traffic environment due to the rapid marine traffics increase and ship handling difficulty by enlargement of ship size is predicted. In this paper, an navigation supporting system proposal made to enhance the safe navigation by providing the collision avoidance informations to the navigator via marine traffic environment assessment. Proposed navigation supporting system displays results of marine traffic environment assessment, degree of the dangers and gives reason of danger which is enhance situational awareness of navigator. For this purpose, results of marine traffic environment assessment which is obtained via real time assessment sent to the designated server and through the connection with navigation supporting system navigator being enable to see all those informations on the computer screen Navigator would utilize those information to make a decision in the difficult waterways and thus safe navigation could be enhanced.

In the modern society where information system based on the computer in organization have been developed over again. A decision support system is one of the most popular topics. The computer have been discussed in relation to management strategy between enterprisers and researchers so far, but the accumulation of data resource and communication foundation have not been attended in actuality. The organic connection between business and information technique have been less progressed than our expectation. At this point of time. such a technical restrution getting removed, We have closed a gap between management strategy and computer. Now we are taking a growing interest in computer use for supporting proceedings decision, a lot of strategic marketing decision is wifely used in such a case, and the technical development is comming to advanced. In this study, I Investigate such a new tendency as strategic program and proceedings decision system. I will especially focus my study on a strategic program and a budget control corporation, so to speak, on strategic budget management system. Concretely the purpose of this study is to investigate what functions the proceedings decision support system requires in order to deal with the problem of strategic level and to practically establish the system with the use of DSS GENERATOR/ARISTOTLE in my laboratory.

In this paper we deal with the logistics brokerage process in which a logistics agent intermediates between vehicle owners and shippers for matching empty vehicles and freights. Based on the Multi-Criteria Decision Making (MCDM) methodology, the proposed agent system matches the most preferred empty vehicle to the shipper and the most preferred freight to the vehicle owner. In the proposed agent system, an MCDM based sensitivity analysis is also used for supporting decision makers under negotiations. Among various MCDM methodologies, Analytic Hierarchy Process (AHP) is utilized in this paper. Although AHP is one of the most popular MCDM methodologies, AHP needs a number of pair-wise comparisons for assessing alternatives and hence may give excessive decision making burden to the decision makers. In this paper, in order to reduce the decision making burden, a preference function based estimation method is proposed. We can expect that the MCDM based logistics brokerage agent can be used as an efficient and effective tool for e-logistics marketplaces on the internet.
