The revolution of new media has overthrown the existing social structure and brought about the changes in the concepts of the space and subject. These changes are identical to the existential issue of the space and subject and to fundamental issue of spatial design. This study will interpret the new media in view of ontology and analyze the characteristics by applying it to spatial design. In this study, the characteristics of new media of ontological viewpoint were divided into six categories containing the process space, the space of exterior meaning, the space of the affairs, interactive subject, playful subject and extension of sense, which were the basis for this analysis. The results showed that the expression characteristics of spatial concept of ontology and subject concepts revealed in the areas of architectural surface, the space of art and installation, and architectural design process.

The purpose of this paper is to suggest diagnosis support system for diseases of mind so that users can make effective decisions without professional knowledge by developing efficient knowledge system and utilizing ontology with which questions and logic inference are possible to diagnose diseases of mind. Furthermore, this diagnosis support system could be applied to supplement previous diagnosis method which depends on experiences by activating the diagnose of mind diseases thru ontology and determining state of mind effectively without technical knowledge. As a result of this experiment, diagnosis support system for diseases of mind was found to be accordance with the result of consulting instructions and show additional relevance thru utility extension.

Discovering the suppliers capable of manufacturing the parts that satisfy buyer requirements via current online market places remains difficult due to semantic differences between what the suppliers can produce and what the buyer wants to acquire. One of the promising approaches to overcome the semantic difference is to adopt an ontology to describe the suppliers' manufacturing capabilities and the buyer requirements that range widely from manufacturing costs to eco-friendly design. Such an ontology dedicated to supplier discovery has yet to be developed. MSDL(Manufacturing Service Description Language) provides the basis for defining terms and their relationships in the ontology. Thus, the objective of this paper is to extend MSDL into a new ontology suitable for supplier discovery in mold manufacturing industry. In addition, a new ontology development method for supplier discovery will be proposed. Finally prototype demonstrations are provided to show a feasibility of the proposed ontology in mold manufacturing domains.

언제 어디서나 자유롭게 인터넷을 사용할 수 있는 다가오는 유비쿼터스 환경에서 원하는 정보를 빠르고 정확하게 찾고자 하는 사용자들의 요구는 중요한 이슈가 되었다. 대량의 정보에 대한 정확하고 의미있는 검색의 해결책으로 제시된 한 분야가 바로 시맨틱 웹이다. 우리는 본 논문에서 시맨틱 웹의 핵심 기술인 차세대 데이터베이스라 불리는 온톨로지를 통합하고 이를 확장해 나아가는 방법에 대해 제안한다. 본 논문에서 온톨로지 통합에 사용되는 기법은 맵핑을 이용한 온톨로지 병합(merging) 기법이고, 이를 바탕으로 하는 상위 온톨로지 확장은 통합된 온톨로지를 메타레벨과 언어레벨로 나누는 작업을 통해 이루어진다. 제안된 방법은 중복되는 온톨로지들을 최소화하여 재사용성을 높이는데 기여한다. 또한 온톨로지들 사이의 개념들 간의 관계를 효율적으로 만들고, 시맨틱 웹뿐만 아니라 나아가 유비쿼터스 웹 환경에서 사용자들이 원하는 정보의 공유를 용이하게 한다.

The realization of intelligence by using ontology is getting attention recently. However, it is necessary to design ontology models suitable to their purpose in order to use efficiently the intelligence realized by ontology. In this paper, we define a cognition cycle for intelligent agents representing a process that the intelligent agents recognize an event and react to it. Moreover, we design an ontology-based intelligent agent, and propose an ontology model that is possible to change the agent's states, to express its emotions, and to expand its intelligence through ontological inference. Finally, we develop an intelligent agent named Helen, confirm the change of her inner states according to the environment and situation, and show the easiness of the extension of her intelligence.

As the complexity of engineering design environment has been increased, it becomes difficult to exchange design data among design support systems. The purpose of this paper is to develop the XML-based Generalized Mechanical Data Exchange Formats(GMDEF) independent of specific mechanical element and to improve the interoperability of them using ontology, in order to integrate diverse design data and facilitate communication between design support systems. GMDEF consists of PartDoc and AssemblyDoc. PartDoc represents the information of a single part. AssemblyDoc represents the relation of parts composing an assembly. GMDEF is validated by GMDEF Schema. GMDEF Schema consists of separated XML Schemas and has flexible architecture to facilitate extension. The ontology is applied to GMDEF Schema to share and reuse vocabularies of specific mechanical elements.

본 연구는 국내 교육과정의 빈번한 변경으로 인해 교사나 학생들이 교육이나 학습에 어려움을 겪고 있는 문제를 해결하기 위해 교육과정이나 교육 단계 등을 온톨로지를 기반으로 자동 연계되어 교육과정이나 체계에 상관없이 교육내용을 접근할 수 있는 방안을 제공한다. 초등.중등.고등학교 간 연계되어야 할 교육내용이 교육과정 변경에 따라 표현되는 상이한 교육과정체계로 인해 다양한 문제를 야기하고 사회적. 기술적 어려움을 가중시키는 것을 완화하고자 본 방법을 제안한다. 본 방법은 교과과정에서 교육 내용의 중심이 되는 성취기준을 기본으로 교육 단원-교육내용 등을 연계하고 또 교육 내용에 따라 제공되는 교육 콘텐츠까지도 연계함으로서 교사나 학생등이 쉽게 교육 내용을 접근하고 사용할 수 있는 장점이 있다.

This paper studies on Multiple Ontology to share and reuse know1edge stored in every system under the Distributed Web Environment using idle resource connected the Internet. Multiple Ontology is to convert to be able know1edge sharing between ontologies constructed by one and the other. This study focuses on as follows; To compose the Distributed Web Ontology multiple system, Construction Method of the Distributed Web Environment and Composition of Multiple Ontology for Know1edge sharing and reuse. System Composed by using the jini technology has constructed extension of heterogeneous systems and effective web computing environment. Also, through 'distribution operation, practical know1edge exchange among Multiple Ontologies under the Distributed Web Environment has been processed excellently.

The increasing interest in ontologies is driven by the large volumes of information now available as well as by the increasing complexity and diversity of this information. These trends have also increased interest in automating many activities that were traditionally performed manually. We are currently engaged in this paper that have realized benefits in productivity and clarity by utilizing UML class diagrams to develop and to display complex OWL ontologies. UML has many features, such as profiles, global modularity and extension mechanisms that are not generally available in most ontology languages. However, ontology languages have some features that UML does not support. Our paper identifies the similarities and differences between UML and the ontology languages RDF and OWL. To reconcile these differences, we propose a modification to the UML metamodel to address some of the most problematic differences.
