Objectives The purpose of this study is to design a research to find clinical factors involved in the decision-making process for determining the constitutional prescription based on prospective clinical data. Methods We have created a draft of the case report form. Therefore, seven constitutional experts was interviewed for additional items to be important used to determine the constitutional prescription in clinic. Interviews were done from December 2012 to March 2014, experts per person 2-3 times, took time of about 120 minutes per interview. Since then, we developed the final case report form through the expert meeting. At the same time, the developing the electronic case report form (eCRF) and the protocol to collect constitutional treatment cases was also discussed. Results & Conclusions The items of the case report form were subject general, lifestyle, health measurement, record of expert, prescription and evaluation after medication. The part of the clinical symptoms of the record of expert allowed to be recorded in the 5-point scale for the collection of quantitative data as much as possible. Assuming a re-visit of the patient, if necessary, twice the recording were to be possible. At the same time, the eCRF and the protocol to collect constitutional treatment cases were also developed. In this study, it will be able to more objectively standardize the medical decision making process that the experts of constitutional prescription decision. As a result, it will be possible to provide the standardized constitutional medical services.

This study addresses the evaluation criteria of multimedia authoring tools(MATs), the way which decision-maker can exclude outlier matrix from group using the concept of the compatibility index, and how AHP can be applied to the selection of MATs in a group decision-making environment. The AHP technique allows an evaluator to quantify the relative importance of elements at each hierarchy and to calculate the composite relative weights for each product(i.e. MATs). This decision process allows setting to priority of the MATs based on the AHP. The results indicated that technical ability of MATs was the most significant factor in affecting their decision, trailed by managerial efficiency and vendor support. To the experts, multimedia data support was the less important than development interface. Also, the results indicated that product A(0.510) was their first choice, trailed by product C(0.286) and B(0.204). Assessing the composite relative weights revealed that expert group's members were consistent with the rankings of decision variables(evaluation criteria variables) statistically in selecting their MATs. Therefore, we believed that expert group's members have achieved sufficient agreement to permit the use of geometric mean to average the group's preference without obscuring the differences of individual opinions.

Semiconductor chip encapsulation process is employed to protect the chip and to achieve optimal performance of the chip. Expert decision-making to obtain the appropriate package design or process conditions with high yields and high productivity is quite difficult. In this paper, an expert system for semiconductor chip encapsulation has been constructed which combines a knowledge-based system with CAE software.

Even though a rapid development of modem medical science, paralysis disease is a highly dangerous and murderous disease. Shin et al. (1978) constructed the diagnosis expert system which identify a type of the paralysis disease from symptoms of a paralysis disease patients by using the canonical discriminant analysis. The decision tree-based analysis, however, has advantages over the method used in Shin et al. (1998), such as it does not need assumptions - linearity and normality, and suggest appropriate diagnosis procedure which is easily explained. In this paper, we applied the decision tree to construct the model which Identify a type of the paralysis disease.

In this paper, we consider the expert's ambiguity and the decision maker's fuzzy goals which are incorporated into multiobjective nonlinear programming problems in order to find a compensatory solution. The proposed method can be applied to all cases of multiobjective problems with fuzzy parameters since the interactive process with a decision maker is simple, various uncertainties involved in decision making are eliminated and all the objectives are well balanced. An illustrative numerical example for nonlinear programming problems with fuzzy parameters is demonstrated along with the corresponding computer output.

이 연구는 박상중 고찬이 제안한 '정책흐름 및 전문가집단 위상변동모형'(Policy Stream and Expert Group Standing Change Framework, 이후 PSECF)을 활용하여 참여정부의 전시작전통제권(이후 전작권) 결정을 분석하는 것이다. 전작권 전환 결정과정에서 노무현 전 대통령과 진보성향의 국가안전보장회의(National Security Committee, 이후 NSC)의 강력한 의지는 정책개발과정의 주요 동인으로 작동하였으며, 국방부 및 합참 등 군사전문가집단의 의견은 정책에 수동적이라는 이유로 철저하게 배제되었다. 전문가집단의 위상변동 측면에서 볼 때 전작권 전환 결정이후 8개월 만에 보수성향의 정부가 출범하게 됨으로써 참여정부에서 전작권 전환을 주도한 NSC는 위상이 약화된 반면에 국방부 및 합참과 같은 보수진영은 그 위상이 향상되었다. 결론적으로 참여정부의 전작권 전환에 관한 이 연구는 상위 수준의 국가정책을 설명하는 정책도구로서 PSECF의 적용가능성을 제고하였다는데 의의가 있다.

Decision-making refers to identifying the best alternative among a set of alternatives. When a set of criteria are involved, the decision-making is called multi-criteria decision-making (MCDM). In some cases, the involved criteria may be prioritized by the human decision-maker, which determines the importance degree for each criterion; hence, the decision-making becomes prioritized multi-criteria decision-making. The essence of prioritized MCDM is raking the different alternatives concerning the criteria and selecting best one(s) from the ranked list. This paper introduces a generic multi-level algorithm for ranking multiple alternatives in prioritized MCDM problems. The proposed algorithm is implemented by a decision support system for selecting the most critical short-road requests presented to the transportation ministry in the Kingdom of Saudi Arabia. The ranking results show that the proposed ranking algorithm achieves a good balance between the importance degrees determined by the human decision maker and the score value of the alternatives concerning the different criteria.

This paper intends to develop a Prototype Expert Collision Avoidance System by introducing expert system techniques into the decision block of anti-collision loop. The problem domain of this study is characterized and specified by combining the concepts of anti-collision loop and knowledge -based system for collision avoidance. Domain in knowledge which may originates from the appropriate sources such as the International Regulations for Preventing Collision at Sea 1972, Marine Traffic Laws, and many texts on the subject of anticollision navigation and good seamanship is acquired and formalized into the knowledge-base system using production rule. Finally, a Prototype Expert Collision Avoidance System is built by using the CLIPS, developed by AIS NASA written in and fully integrated with the C language, and some test-and-run results of the system are demonstrated and examined. The author considers the proposed system which is named PECAS to be meaningful as a test bed for a further refined Expert Collision Avoidance System on board the Automated Ship.

The attraction of using expert system in operator support systems for modern plant is that it offers a way of dealing with the problem of information overload that can occur during a severe disturbance at a modern industrial plant. During such a disturance the volume of information presented to operators may be such that they are unable to decide quickly what is important and what is not. Therefore, arriving at a correct diagnosis of the initialling fault may be delayed. An expert system operator sup-port system is a means of focusing attention on what really matters and cutting out the rest. This paper presents the development of prototype expert system which detect the fault part, machine, system and decide action priority. This prototype expert system has 6 sub- system which is Interface Manager, Decision Maker, Inference Engine, Knowledge base, Simulatio, and D.P System ( Diagnosis and predictor)

PID제어기는 산업자동화 설비에 널리 쓰이고 있다. 하지만 시스템 특성이 변화하면, 정밀제어를 위한 매개변수 결정과 동조가 쉽지 않다. 이를 해결하기 위한 방법으로 본 논문에서는 PLC를 사용한 전문가 자동동조 PID 제어기를 제안하였다. 전문가 자동동조 알고리즘은 Ziegler-Nichols의 계단응답법과 전문가 지식을 기초로 하였다. 제어의성능 실험은 가변부하시 유도모터 속도제어의 수행에 의하여 확인하였다.
