This study was a phenomenological approach to the substance and meaning of large-group discussion activities in the kindergarten. Results of this study showed phenomena of the management of large-group discussion to be : 1) interchange in the natural fields of knowledge, 2) the fields of shared laughter and humor, 3) the exchange of glances individually between a teacher and children as well as children to children, 4) a bridge to connect one activity to another, 5) the guarantee of freedom in the limited space while keeping order, 6) the making of a way to connect individual children's inner self with the world, 7) conflicts between standardized themes and generated themes.

The utilization of horticultural tools in Korea is historically viewed through limited materials. The garlic shown in the birth myth of the Korean nation appears to be the first record of horticultural foods. Only the fragmentary knowledge is available on the production and utilization of horticultural foods during the eras from Old Chosun to the Three States and the Unified Shilla. It seems that mutual exchange of horticultural foods between the Three States and neighbor countries was very active. Kinds of horticultural foods utilized were more variable in the era of Koryo dynasty. The situation on horticultural foods during Chosun dynasty is comparatively well known through published agricultural books and other literatures.

Since the 1990s, the advancement of semiconductor technology has resulted in the development of microprocessor technology, auxiliary computer technology, and application technology such as intelligent algorithms (neural network, fuzzy, etc.). These based the development of intelligent machines. An agent is autonomous software that recognizes environment, exchanges knowledge with other agents and makes decisions. We designed agent-based sensor structure. For the purpose, first, it modeled the function of an intelligent machine. Second, it designed sensory function on the agent level.

Human history show the whole society changed rapidly and found that the momentum and foundation of such change is " the advanced technology ",which is, the advanced knowledge. The world is newly established based upon openess, spaclalization and globalization, and the each nation and company should have to adopt all the existing frames to follow the new world reality. Today is the changing period from industrial society to information society, and information technology plays a great role. As the information society moves ahead, world economy and social infrastructure will be based upon network society and various information systems will make an integrated information system. This paper presents that to establish interior design related information in the age of information with radical change of previous way of thinking, cooperative information exchange system. Also substantial and effective communication systems should be made and continuing cooperation system of interior design information area should be formulated.d be formulated.

First, I'd like to express my great respect to the highly developed environment-friendly and organic agriculture in South Korea, especially in this region of Yangpyong. I've heard that rural farmers and city people cooperated together to develop the environment-friendly agriculture in Yangpyong. I believe Japanese farmers and people can learn a lot from the experience of your people. We'd like to exchange our knowledge and experience to develop environment-friendly and organic agriculture in both countries, for we share a lot in common. In this paper, I'd like to introduce how the Japanese have been developing organic and environment-friendly agriculture, and how we are working with the official organic standard and building the social structure to encourage the overall development of organic and environment-friendly agriculture.

Data dictionary is a collection of meta-data, which describes data produced and consumed while performing business processes. Data dictionary is an essential element for business process standardization and automation, and has a fundamental role in ERP application management and customization. Also, data dictionary facilitates B2B processes by enabling painless integration of business processes between various enterprises. We implemented data dictionary support in SEA＋, a component- based scalable ERP system developed in ETRI, and found out that it's a plausible feature of business information system. We discovered that data dictionary promotes semantic, not syntactic, data management, which can make it possible to leverage viability of the tool in the coming age of more meta-data oriented computing world. We envision that business data dictionary is a firm foundation of adapting business knowledge, applications and processes into the semantic web based enterprise infra-structure.

In many automated systems, such as manufacturing systems and process plants, a fieldbus is a very important component for the exchange of various and sometimes crucial information. Some of the information has a tendency to rapidly lose its value as time elapses after its creation. Such information or data is called real-time data that includes sensor values and control commands. In order to deliver these data in time, the fieldbus network should be tailored to have short delay with respect to the individual time limit of various data. Fine-tuning the network for a given traffic requires the knowledge on the relationship between the protocol parameters such as timer values and the performance measure such as network delay. This paper presents a mathematical performance model to calculate communication delays of the Profibus-FMS network when the timer value and the traffic characteristics are given.

As South Korea is becoming the aging society and the relation between information and daily living getting very close, the information alienation of the old population could lead to a social problem. This paper analyzes the cause of the information gap observed from the old population of South Korea and advanced countries during the transition period to the digital economy era.

Digital CAD models are one of the most important assets the manufacturer holds. The trend toward concurrent engineering and outsourcing in the distributed development and manufacturing environment has elevated the importance of high quality CAD model and its efficient exchange. But designers have spent a great deal of their time repairing CAD model errors. Most of those poor quality models may be due to designer errors caused by poor or incorrect CAD data generation practices. In this paper, we propose a rule-based approach for healing CAD model errors. The proposed approach focuses on the design history data representation from a commercial CAD model, and the procedural method for building knowledge base to heal CAD model. Through the use of rule-based approach, a CAD model healing system can be implemented, and experiments are carried out on automobile part models.

This paper describes diagnosis strategy of the Flexible Multiple Fault Diagnosis Module for forecasting faults in system and deciding current machine state form sensor information. Most studydeal with diagnosis control stategy about single fault in a system, this studies deal with multiple fault diagnosis. This strategy is consist of diagnosis control module such as backward tracking expert system shell, various neural network, numerical model to predict machine state and communication module for information exchange and cooperate between each model. This models are used to describe structure, function and behavior of subsystem, complex component and total system. Hierarchical structure is very efficient to represent structural, functional and behavioral knowledge. FT(Fault Tree). ST(Symptom Tree), FCD(Fault Consequence Diagrapy), SGM(State Graph Model) and FFM(Functional Flow Model) are used to represent hierachical structure. In this study, IA(Intelligent Agent) concept is introduced to match FT component and event symbol in diagnosed system and to transfer message between each event process. Proposed diagnosis control module is made of IPC(Inter Process Communication) method under UNIX operating system.
