  • A prototype expert system for normal concrete mix design was developed using an technical consulting system development tool, EXSYS Professional. The knowledge contained in the system was obtained from the standard specifications of Korea Concrete Institute, American Concrete Institute and from the related British Standards. The knowledge base and user interface will be expanded to cover wider scopes of the problems. If the system is successfully developed as an operational system, it will produce a great deal of economic benefits by reducing the time and money needed to obtain an expert's judgement and experience in decision making for repetitive tasks related to concrete mix proportions.

  • Since, human error is a major factor contributing to disaster during start-up of operation in Boiler plant. it is necessary to develop an automation system which prevent mode of operation that are known to be dangerous and to bring a loss of energy. The aim of this study is to suggest a model for the computer-aided synthesis of operation sequence as a part of automation system for start-up operation. Synthesis is accomplished by the formation of a hierarchical network of goals which decide sequence of operations. Hierarchical Network is formed by using method which upper goals ( i.e. upper operation al situation) are classified by the function of themselves into lower goals (i.e. lower operational situation). Knowledge for deciding operation sequence is generated by putting In order the knowledge of hazard operation and energy management.

  • It is critical to determine the appropriate actions for safe landing of an aircraft in an emergency situation. An expert system can be very useful for this purpose. An expert system specifically for jet fighter $F-\bigcirc\bigcirc$ has been developed. Its knowledge base contains the standard procedures provided by various flight manuals and the expertise of human specialists such as pilots and emergency management personnels. Advising procedures are represented by an IF-THEN format in the developed rule-based expert system. Advises are provided in real time during the entire flight processes of ground, takeoff, inflight, and landing. The developed system would significantly increase the survivability of pilots and aircraft, while decreasing operational costs of emergency management personnels. By modifying the knowledge base, the developed system can also be applied to other types of aircrafts including civilian airlines.

  • A knowledge based forecasting system for special days has been developed for the economic and secure operation of electric power system. If-then production rules has been adopted in this system to be used in various environmental conditions. Graphic user interfaces enables a user to access easily to the system. The simulation based on the historical data have shown that the forecasting result was improved remarkably when compared to the results from the conventional statistical methods. The forecasting results can be used for power system operational planning to improve security and economy of the power system.

  • The city of 'G' has been made a number of achievements with its science program as a part of public library's cultural program during the last 5 years. Recently, the national science centre has been established in the same city, the debate is now needed whether the science program in the public library have reasons to be maintained or to be reduced. The aim of this research is on the operating strategies of the science program in the public library. The research methods include case studies of operational strategies in domestic and foreign science centre, the level of satisfaction of local citizen on the science program, the vision of science program in the advancement of public library in the $21^{st}$ century. In results, the research proposes that the science program in public library should be maintained, but with locally characterised programs. In addition, the study also advised on the provision of scientific information, the strengthened search functions, and the development of user-centred services for those in science fields.

  • 조직유효성은 오랫동안 조직 연구의 가장 중심적인 주제가 되어 왔지만, 그 개념은 연구목적과 연구대상에 따라 조작적 정의가 다양할 뿐만 아니라, 여러 가지 측정 요소로 구성되는 불확정 개념으로 보편적인 합의가 이루어지지 않고 있다. 본 리뷰에서는 공공조직과 사조직, 연구조직과 생산조직 등 연구대상의 유형별로 측정변수를 파악하여 하위변수로 가장 많이 연구되었던 심리적 지표였던 직무만족과 조직몰입에 대해 살펴보았으며, 향후 조직유효성 관련 연구의 방향과 주제를 설정하고 확장시켜 나가는 데 공헌하고자 하였다.

  • 본 연구에서는 직관에 대한 초등 교사들의 '전문화된 내용 지식'(SCK)를 연구하기 위하여, www.mathlove.net에 탑재된 초등기하편 시즌 I의 1번에서 15번까지의 문항 중 문제해결 과정에서 직관이 필요한 8개 문항을 교육 경력이 다양한 8명의 초등 교사들에게 투입한 후, 회수한 검사지를 바탕으로 초등 교사들의 직관 정도를 조사 분석하였다. 연구에서 사용된 문항들을 3가지 유형으로 분류하여 각 유형별로 문항별, 교육경력별로 특징들을 조사하였는데, 연구 결과 1명의 교사를 제외한 나머지 초등 교사들이 문제해결 과정에서 보여준 직관에 대한 SCK는 3가지 유형 모두에서 전반적으로 낮은 것으로 분석되었다.

  • For the effective use of satellite communication transponder, tests for the payload system such as IOT(In-Orbit Test), RPM(Routine Payload Monitoring), CSM(Communicatios System Monitoring), and REV(Remote Earth-Station Verification) have to be conducted. Those tests are used in order to verify the condition and generic design of the satellite, to provide a database for operational calculations, and to maintain the quality of communication services. As the satellite communication system gets with wider expansion with higher complexity of operation, tests for the communication system also need more complex operation that usesophisticated computer-controlled measuring system. For and C language based measurement functions, which uses GPIB protocol and SCPI commands. But SICL requires knowledge of BASIC and C language as well as GPIB and SCPL system. This paper introduces a new language called CALSTEP-Control and Access Language for the Systems of Test Equipment and Payload. This language is designed for the operator to perform the tests for the satellite communication system without any special knowledge that is mentioned above. This language has very limited number of commands which are to be used to control the payload system and test equipments to perform IOT and CSM, and those commands are very readable and easy to understand, so an operator without any knowledge of BASIC and C programming language, or SICL and SCPI command can use it.
