Expert system, having knowledge of human being and Know-how, subsitudes computer for highly judgement and operation of Expert. This is a applicative part of artificial intelligence in computer operation. This paper is show Knowledge-Representation Method for Meta-Reasoning to us. Meta-Reasoning is reasoning about reasoning and reasoning about knowledge structure of reasoning. In using Expert system program, I research using Meta-Knowledge in behalf thinking: logically pursuitable goal. This papers present shows the knowledge-Representation Method for Meta-Reasoning using Meta-Knowledge in Expert system.

This paper is a study on the knowledge-representation for fuzzy-reasoning and the fuzzy-reasoning for the process of natural language in Expert-system. When the user want to deal indefinite data in Expert-system, it's no matter whether he is an expert or not. he may make use of existing way which is based on probability. I tried to operate Expert-system in fuzzy theory which is simillar to Man's thinking procedure. As the type of knowledge-Representation in this paper, the fuzzy-reasoning is realized for proccessing the natural language in interface Expert-system with user on the ground of the fuzzy theory.

In an Expert-system, it is method to express an efficient and fast extraction implement for man-expert's systematic and factual knowledge and it efficiently. In this study, I want to consider expression method about reuse of the knowledge which is related to the repetition, unification, editing of knowledge to carry out meta-reasoning, that is the highest reasoning. I want to present expression method to join the part which is repeated and to improved management efficiency of reasoning reusing knowledge and using ontology.
Ad-hoc Network에서 TCP 성능 향상을 위한 기법
박경우 朝鮮大學校 統計硏究所 2006 統計硏究所論文誌 Vol.8 No.1
Ad-hoc network에서는 네트워크를 구성하는 노드들의 이동으로 인하여 일시적인 연결 실패와 경로 변경이 자주 발생한다. 모든 패킷의 손실이 혼잡 때문이라고 가정했을 경우, 이러한 환경에서 TCP 성능은 매우 빈약하다. Ad-hoc network에서의 TCP 성능 향상을 위한 연구는 계속되고 있지만 이것들의 대부분은 네트워크 계층 또는 하위 계층으로부터 피드백이 요구되어진다. 본 논문에서는 경로 변경을 자주 발생시키는 잘못된 패킷 전달을 검출하고 응답하므로써 TCP 성능을 향상시키는 새로운 접근 방법에 관해 연구한다.

The author reached following conclusions to he implemented as preventive plans for criminal psychotis in Korea. These conclusions are made based upon the author's experience of treatment of criminal psychotics for last four years at Korean Institution of Forensic Psychiatry, as well as theory of community psychiatry, preventive psychiatry and crime prevention. 1) It is strongly suggested that Korean government should provide a positive support for a mental health policy and the government should enact a mental health policy suitable for the current situation of the country, provide it with proper budget and set up a mental health department under the Ministry of Health and Social Affairs. Government should also establish a National Institute of Mental Health to function as connecting with other related insitutions. 2) It is suggested that currently existing asylum for psychotics should he managed as a better facility equipped with improved environment and treatment team. It is also suggested that 12 of more National Mental Hospitals be established and equipped as facilitie with a systematic and efficient treatment team for deinstitutionalization of psychotics. 3) It is suggested that all the public, including those involved in prevention and treatment of criminal psychotics, be educated and illuminated in regard to mental disorder, criminality and violence of psychotics. coping with relapse of psychotics. and helping for adjustment of psychotics in community. These educational plans should be implemented as a public movement. It is also suggested that an efficient educational program on community psychiatry be provided for psychiatric residents and that more courses on psychiatry he set up in colleges of medicine, as well as continuing education for those involved in treatment of patients. 4) A community mental health policy be implemented in the near future, personnels employed at mental health centers should be able to facilitate prevention of criminal psychotics to full range. Since it is not realistic to expect prevention from psychiatrists' effort alone. Team approach should be considered including nurses, psychologists, social workers, and rehabilitation workers, and an active participation and/or a close network should be made among legal, educational, and social welfare facilities, and their personnels. Theory of preventive psychiatry and crime prevention should be applied in order to prevent relapses of criminal psychotics.

Optimal values of the design variables for heat sink with 7 × 7 pin-fins are obtained for two different cross-sectional fin areas by integrating the computational fluid dynamics and mathematical optimization technology. In the pin-fins heat sink, the optimum design variables for fin height (h), fin width (D), and fan-to-heat sink distance (c) can be achieved when the thermal resistance (θ_(j)) at the junction and the overall pressure drop (Δ_(p)) are minimized simultaneously. To complete the optimization, the finite volume method for calculating the objective functions and SQP method for solving the constrained non-linear optimization problem are adopted.
