This review describes the overall knowledges of parkinson's disease. There are involved the causes. chemical characteristics, clinical features including tremor. bradykinesia, and rigidity. evaluation of movement disorders. and physical therapy of parkinson's disease. People who are diagnosed with parkinson's disease experience movement disorders that, if not managed, can lead to considerable disability. Before treated with parkinson's disease, it is important to recognise the pathogenesis of that. Then we need to develop physiotherapeutic programs based on the pathophysiology of parkinson's disease.

This paper describes some research of Computer-Aided Process Planning and Die Design of Hot Forging for axisymmetric parts produced by the press. An approach to the system is based on knowledge based system. The system has been written in AutoLisp with personal computer. Knowledges for process planning & die design are extracted from the plasticity theories, handbooks, relevent references and empirical know-how of field experts in hot forging companies. The developed system is composed of five main modules, such as input module, process planning module, die design module, flow simulation module and output module which are used independently or in all. The final output is generated in graphic from. The developed system which aids designer provides powerful capabilities for process planning and die design of hot forging. This system also provides approximate flow pattern.

This study investigated the factorization concept development level of 3rd grades in middle school, the success of factorization problem solving, and the completion of factorization analogy tasks and science concepts analogy tasks. This study's results are followings. 1. Based on Sfard' reification levels, we classified students' factorization concept development levels from level 0 to level 3. As the students' development level was high, they tended to succeed the factorization problems gradually. 2. Experiencing factorization tasks which made students arrange factorization expressions hating same characterization, students ' factorization problem solving was improved. And, as the students' development level was high, they tended to attend to internal structural relations in factorization analogy tasks. 3. Analogy in factorization wasn't interrelated with analogy in science concepts. It said that analogy depended on the knowledges with it.

SiOB is an essential part of slim optical pickup, where the silicon mirror, LD stand, silicon PD are integrated and LD is flip chip bonded. SiOB is fabricated with bulk micromachining. Especially the fabrication of silicon wafer with stepped concave areas has many extraordinary difficulties. As a matter of fact, experiences and knowledges are rare in the fabrication of the highly stepped silicon wafer. The difficulties occurring in the integration of PD and SiOB, and highly stepped patterning, and silicon mirror roughness and how-to-solve will be discussed.

This paper demonstrates an AI application for representing operator's heuristic knowledges in implementing process control. AI controller constitutes servo and regulatory controller, respectively. The knowledge base for servo controller was designed to obtain the process output with respect to the desired set-point in short period. The regulatory controller was to provide smooth output near the set-point. The AI controllers was implemented in Turbo-PROLOG on IBM-PC. For the parallel processing, Turbo-C was linked to calculate the process output. The result shows that this AI controller can be well suited not only for minimum phase but also for non-minimum phase. This controller may be used as a back-up controller for rather extensive expert system.

Microorganism are centIal core to biosphere sm1ainablity and biogeochemical cycles on this earth. Most of food, medical and pabamceutical new materials through biotechnology are derived from many kinds of microorganisms. Microorganisms are important resources of biotechnology. Beside these, micorbial diversity is key to explore the frontiers of knowledge about the strategies and limits of life. Through the micorotganisms, we can monitor the environmental changes and conditions. Moreover, the microorganismsms play a role in conservation and restoration of higher plants and animals. And we can get a lot of ecological, evolutionary knowledges from microbial models. In spite of these importances, the microbial diversity is not properly evaluted because of their unculturablity. Only 0.001 - 3 % of total bacteria in natural habitats are cultumble and the rest are viable but uncultumble. Only 3,100 species are listed up in the Bergey's Manual. Considering the symbisis and estimated numbers of insect are more than 800,000, the symbiotic microorganisms are about 1,000,000 species. Recently, by using the genetic and molecular technics, the microbial diversity is now unveiled. In this symposium, the genetic, species and ecological diversity will be given. given.

A computer-aided process design system for axisymmetric deep drawing products has been developed. An approach to the system is based on the knowledge based system. Knowledges for the system are formulated from the plasticity theory handbooks experimental results and empirical knowhow of the field experts. the system is composed of four main modules such as geometrical design test & rectification and user modification. The input to the system is final sheet-metal object geometry and the output from the system is process sequence with intermedi-ate objects geometries and process parameters, such as drawing load blank holding force clearance cup-drawing coefficient.

This paper attempts to find the sources of materials technology innovation and to analyze the relationships between the sources and materials technology innovation. Starting from the traditional hypothesis on the innovation sources (e.g. technology-push, demand-pull and user-supplier), materials scientific knowledges, materials processing technologies and users' needs are found as three main sources of innovation in materials technology. There are not only close interactions between the sources and materials innovation, but also the interactions among the sources of innovations play important roles for materials technology innovation. This paper discusses the characteristics of interactions between sources of innovation in materials technology. This study on the sources and interactions among sources may provide important information for policymaking in materials technology

This analysis of the children's books used in kindergarten classroom activities focused on educational meanings of the books. The analysis included books used in 8 kindergartens in 1999. Finding were that 76.6% of books were published in the 1990s; 60.7% of the lines per page were over 5 lines; only 55 of 542 books were recommended as good books by public institutions; half of the books provided factual knowledges or informations; Korean books included more realistic than fantastic fiction while the opposite was true of foreign books; in Korean books, male characters appeared far more often than females; 70.1% of the themes of the books were related to the ten themes of life suggested by the Ministry of Education; and 44.8% of the contents included moral values while only 17.5% of those included adventure, hobbies or pastimes.

The main purpose of this study is to provide basic data for the development of secondary Home Economics education curriculum and program by investigating the recognition perceived by Home Economics teachers. We have done statistical analyses of 237 questionnaires on the Home Economics teachers' recognition. The results are as follows: 1) The respondents evaluated the necessity of Home Economics education in secondary school, application of aquired knowledge and technical skill and learning by practical experience, highly. 2) As for the contents of Home Economics education curriculum, the respondents place a high value on the field of Meal Management, Child and Family Studies, Home resourse Management and Consumer life, Clothing Management, and House Planning and Management, in the order. 3) The most important educational concepts are knowledges and understanding for the human beings.
