In developing an Expert System(ES), there are two ways. One is to develop an ES using AI(artificial Intelligence) languages and another using ES-development tools. CLIPS is an ES-development tool and has a powerful inference engine in it. Using the tool like CLIPS, knowledge engineer can concentrate on constructing a knowledge base without wasting time in developing an inference engine. However, CLIPS is lack of user-friendly interfaces for both knowledge enginners and users. Because CLIPS was developed in USA, it can not afford to use Korean language. Therefore, several user-friendly interfaces including hmenu, htille, hpcxdisplay were develpoed and added to CLIPS. CLIPS with the interfaces is called HCLIPS(Hangul CLIPS) in this paper. HCLIPS provides a new I/O device to be utilized for expert systems in Korean. HCLIPS can be efficiently used for developing expert systems in agriculture and consulting farmers interactively who are not familiar with computer programming and ES itself.

전문가시스템 개발 도구인 HCLIPS를 이용하여 오이의 병해 및 영양 장애 진단을 위한 전문가시스템이 개발하였다. 농민과의 접견 및 문헌 조사를 통해서 지식베이스를 구축하였으며, 사용자의 이해를 돕기 위해 병해 및 영향 장애의 영상 자료를 포장 촬영 등을 통해서 얻었다. 개발된 전문가시스템을 잘록병 등 11가지의 병해와 질소 결핍 등 12가지의 영양 장애를 진단할 수 있으며, 진단 결과에 대한 상세한 설명과 농약 사용법 등의 방제 대책까지 제공한다. 이 전문가시스템에 대해서 농민 및 전문가들을 대상으로 진단의 정확도 및 사용 편리성을 검증을 수행한 결과, 확신도의 차이는 있었으나 100%의 진단 정확도를 나타냈으며, 검사대상자의 88%가 사용하기에 편리하다고 답하였다.

An expert system for cucumber disease and nutritional disorders(ESCD) was developed using HCLIPS in which several interface programs were added to CLIPS developed in NASA. The knowledges for constructing knowledge base was obtained from interviews with farmers, agrochemical vendors and employees of agrochemical company. The ESCD is able to diagnose eleven diseases and twelve nutritional disorders which farmers, agrochemical vendors and employees of agrochemical company. The ESCD is able to diagnose eleven diseases and twelve nutritional disorders which could frequently found in fields and greenhouses. Validation of ESCD by twenty -four experts proved a possibility of its practical use for diagnosing cucumber diseases and nutritional disorders in the future.

Since parameters influencing the indoor environment of livestock building interrelate so complicatedly, it is of great difficulty to identify the exact cause of environmental problems in a livestock building. Therefore, the approaches for the problem solving based on experience not numerical calculation will be helpful to the management of livestock building This study was attempt to develop the decision supporting system to diagnose environmen- tal problems in a livestock building based on an expert system and a neural network. HClips$^3$), attaching the Hangeul user interface to Clips which is known as a powerful shell for develop- ing expert system, was used. The multilayer perceptron consisting of 4 layers including back propagation learning algorithm was adpoted, which was rapidly converged within the allowable range at 50,000 learning sweeps. The expert system and neural network seemed to work well for this specific application, providing proper suggestions for some environmental problems: particularly, the neural net- work trained by an environmental problem and its corresponding answer with certainty factor, produced the same results as those by expert system.

본 연구에서는 시설 재배 수박에 자주 발생하는 8가지 병과 1가지 생리장해 증상을 진단할 수 있는 수박병 진단용 전문가시스템인 WDES를 개발하였다. 사용된 전문가시스템 개발도구로 HCLIPS를 사용하여 한글 입출력이 가능하게 하였다. WDES의 지식베이스는 35개 IF-THEN 형식의 규칙으로 구성되었으며 추론과정은 순방향 추론방식을 채택하였다. 질문 문항별로 도움말, 도움그림, 질문이유 등의 도움기능을 포함시켜 사용자가 질문 문항에 대한 답변을 쉽게 할 수 있도록 하였다. 수박재배자와 전문연구자들이 WDES를 사용해 본 결과 WDES의 타당성과 실용가능성을 인정할 수 있었다. 실제 수박밭에서는 다양한 종류의 병과 생리적 장해가 함께 발생되고 있으므로 WDES가 실용적으로 사용되기 위해서는 각종 병 증상들에 대하여 좀더 세부적인 특징을 파악하여 지식베이스 내의 규칙을 보완해야 한다.
