  • The purpose of this study was to develop an environmental education programs utilizing dietary life. On this study, the environment education programs developed upon dietary life were implemented to the third graders to see how they affects their environmental literacy and specific aims of this study. The results were as follows; The first of all, we should start by outlining the relationship between our environment and our diet. We can use the resulting outline to develop the environmental education programs with the purpose of improving our diet. Secondly, there were significant changes in environmental recognition between the control group and the test group. Thirdly, the environment educational programs based on dietary life could enhance knowledges, emotions and activities about environment. As a conclusion, the environmental education programs could confirm its value as the environmental education programs in this study, and it could bring out positive influence on environmental literacy of third graders in the elementary school.

  • This paper describes some development of Computer-Aided Process Planning System for cold-forging of rotationally symmetric parts(soild shape and solid-can combined shape) produced by the presses or formers. Using the developed system, forming sequences for producing final product are generated as graphic forms and process names, preform dimensions and process parameters(load, punch pressure, die pressure) are generated as routing sheets. Konwledges for forming sequence and process parameters are extracted from process limitations, plasticity theories, handbooks, relevent refferences and empirical know-how of experts in cold forging companies. Among extracted knowldeges, general and consistent knowledges are represented as design rules and are constructed as knowledge base. The developed system provides more powerful tool for through checking the producibilities of design, conformation of appropriate forming sequences and discoveries of new possibility. The results of the developed system are in good agreement with the practical data.

  • This paper describes an experimental Knowledge-Based Control System, named KBCS, for manufacturing and assembly. The KBCS of five parts and function : data-base, knowledge acquisition, optimization, and graphic monitoring. The KBCS is utilized for a FMS which is of five machine centers and automatic assembly lines. Each machine can perform almost all manufacturing functions which some difference in efficiency. Buffers store temporarily the incoming components and the outing components. Parts arrive at assembly lines after many steps of manufacturing, and the transfer path and time are determined by procedural knowledge of control systems. Nine different incoming components are set up. The total control system is expected to perform four algorithms, timing algorithm ,sequencing algorithm, penalty algorithm, and cart algorithm. The construction of controller require basic components of manufacturing systems in which knowledges are formulated on the base of the results and the repeated simulation of KBCS with graphic monitoring system. Simulation results by KBCS are compared with those by the other rules of manufacturing.

  • This study was carried out to analyze Pinus densiflora forest in islets of southwestern coast of the Korean peninsula by the phytosociological methods. As a result of the investigation of 26 quadrats, the pine forest was classified two communities and six subcommunities : Ardisia japonica - Pinus densiflora community and lsodon japonicus - Pinus densiflora community, and Farfugium japonicum subcommunity, Quercus serrata subcommunity, Typical subcommunity of Ardisia japonica - P. densiflora community, Juniperus rigida subcommunity, Pourthiaea villosa subcommunity and Typical subcommunity of lsodon japonicus - P. densiflora community. The subsidiary knowledges from this study provide practical information to clarify the syntaxonomy of natural pine forest of the Korean peninsula by the phytosociological methods.

  • The helicopter system is non-linear and complex. Futhermore, because of absence of an accurate mathematical model, it is difficult accurately to control its attitude therefore, we propose a fuzzy control technique to control efficiently its elevation angle and azimuth one. This controller is on the basis of expert's knowledges and his experiences. The simulation results using MATLAB are introduced.

  • As the well-being or quality of life of a population is the common interests, a lot of people are interested in wines. They are willingness to share wine knowledges with other wine experts on the web. Therefore the study for information retrieval system and inference engines are needed to get relevant search results about wine types and suitable wines for given foods. This paper discusses an approach to the architecture of agent-based semantic web services in wine ontology.

  • The paper proposed a basic architecture of an agent system to support exchange and sharing of design informations by means of ACL(Agent Communication Language) which can represent design informations and knowledges. Based on the architecture of the agent system a ship initial design agent system was implemented in order to show the effectiveness of the agent-based system. The basic architecture of the agent consists of an ACL handlerand CORBA(Common Object Request Broker Architecture) objects for the exchange of ACL messages in the heterogeneous and distributed environment. The ACL handler can process expressions of knowledge and manage communication messages among the agents. The paper mainly focuses on the implementation of the ACL handler. The ACL handler consist of a KQML(Knowledge Query and Manipulation Language) handler that manages KQML messages, a conversation module, and a content handler that handles message contents. The conversation modulo implements conversation policies and checks all messages if they are allowable and meaningful messages based on the conversation policies. The implemented agent-based system was applied to the ship initial design to show the handling procedure of the agent system.

  • Anatomy: Advanced knowledges of cellular and molecular biology led to the development of therapies of rheumatoid arthritis(RA). Rheumatoid arthritis (RA) is a chronic, recurrent, systemic inflammatory disease and results in major deformity or dysfunction of joints. Etiology: Rheumatoid arthritis is now concevied as autoimmune disease. There have been many trials to define the immunological changes in rheumatoid arthritis. But now pathogenesis and significance of immunoglobulin complement and rheumatoid factor are not full accepted. Syndrome: Joints are characteristically involved with early inflammatory changes in the synovial membrane, peripheral portions of the articular cartilage, and lation tissue(pannus) forms, covers, and erodes the articular cartilage, bone and ligaments within the jiont capsule. Inflammatory changes also occur in tendon sheaths(tenosynovitis), and if subjected to a lot of friction, the tendons may fray or rupture. Extra-articular pathological changes sometimes occur, these include rheumatoid nodules, atrophy and fibrosis of muscles, and mild cardiac changes. Treatment: Tumor necrosis factor(TNF) inhibitor for the treatment of rheumatoid arthritis(RA) induces not only significant improvement of symptoms and signs of RA but also substantial inhibition of progressive joint damage.

  • Polarisation of biological and psychosocial aspects of psychiatry is nowadays main stream. Current knowledges of the interaction between biology and psychology make it possible to consider a truly integrative approach of the two aspects. Research findings suggest that the neuronal plasticity is the key mechanism to answer how the mental function work to an environmental stimuli and how the psychotherapeutic approach work on the brain. Advances in neuroscience research have led to a more sophisticated understanding of how psychotherapy may affect brain function. Even though there have been a tremendous efforts to find out the neurobiological mechanism of mental function, the answer is at best premature. In this article, research findings about of neuronal plasticity, implicit memory, animal studies which were associated with psychotherapy and psychological aspects were reviewed.
