In this paper, we implemented design pattern retrieval system for efficient management and reusability of design patterns. Pattern is consisted of property information and meta information. Property information is used for similarity measurement on classification and retrieval of patterns. Meta information is used for UML modeling of patterns. We classified design patterns with the empirical scope in addition to Gamma's basic classification.

Although organizing standardized metadata is important for effective management of cultural heritage information, current metadata are represented differently according to the properties of the resources or objectives of the organizations in which they are accumulated. This research compared 6 different metadata formats and created 18 data elements for constructing databases. A religious architecture heritage information database was constructed based on 72 historic religious architectures, each composing of three parts. An ontology based on religious architecture heritage information was designed using a revised CIDOC-CRM, and was developed with a semi-automated corpus program.

Study on the class using XMI Meta model and XML MetaDats has significant difference from the method of Data creation which is widely used. Most of MXL System are focusing on the editor funcition, Database connection and Generation of Markup language. Unlikelly, however, this study has focused on the creation of Markup language of Class MetaData which are extracted from MXI data modedl. In addition to that, the attribute of unit element within the class and the relationship between the classes within the model were set to be given and expressed respectively. For the generation of Markup language, XML schema was used to declare the detail data type.

데이터 웨어하우스는 기업의 의사 결정 과정을 향상시킬 수 있게 하는 정보기술이다. 대표적인 정의로는 '기업의 의사결정 과정을 지원하기 위한 주제 중심적이고 통합적이며 시간성을 가지는 비휘발성 자료의 집합 '이다.[1] 즉, 기업들이 보유하고 있는 분산된 대량의 데이터를 추출, 변환, 통합하여 요약된 읽기 전용의 데이터베이스로 구축함으로써, 경영분석이나 기업내의 의사 결정 지원 자료로 주로 활용된다. 데이터 웨어하우스의 경우, 일반사용자는 웨어하우스내에 저장된 데이터를 직접 이용하는 경우가 대부분이다. 따라서, 데이터의 구조와 의미에 대한 일반 사용자의 이해가 필요하게 되었다. 즉, 데이터의 추출 및 정제규칙, 데이터의 통합규칙, 요약알고리즘, 데이터 처리스케쥴 등을 알아야만 한다. 메타데이터는 최소한의 데이터 구조, 데이터의 요약에 사용된 알고리즘, 운영 데이터베이스와 데이터 웨어하우스사이의 대응관계와 같은 정보를 포함하여야 한다.[3] 여기서 변환프로세스에 대한 정보를 데이터의 형식에 대한 정보와 일반적인 데이터들과 차별화하여 메타프로세스라 한다.[5] 메타프로세스는 데이터를 변환하여 데이터 웨어하우스에 적재하는 과정에서 생성되는 메타데이터의 일부로써 데이터 웨어하우스에 통합된 자료들이 어떤 변환과정을 거쳐 생성된 자료인지를 알려주는 변환프로세스에 관한 정보를 제공한다. 본 연구에서는 대부분의 데이터 웨어하우스에서 구현되고 있는 메타데이터들은 데이터 항목의 속성정보를 위주로 한 것이며, 변환 프로세스와 관련된 데이터 관리가 미약하다. 따라서, 데이터 웨어하우스의 메타데이터 중 메타프로세스 정보의 추출 및 관리 시스템을 제안하는 것이다.

The paper has tried to analyze the sense of 'meta-praxis' in the educational discourse. Against the dichotomy of theory vs practice, the senses of practice and 'meta-praxis' can be hold under the Greek conception of human activities such as theoria, poiesis and praxis. We can establish the meaning of meta-praxis contrasted with one of metaphysics, not with one of meta-theory. Some significant points included in the concept then have been minutely examined so as to lead us to get the recursive structure and practicability. The Buddhist notion such as 'Well-Rounded Discretion' and the linguistic one such as 'Grand Father' throw light on the educational practice and discourse. These are ones that we never fail to recognize in terms of 'meta-praxis'.

This paper discusses the shaping of game culture and the socio-cultural functions of game-making events based on co-production ideation by meta-analysis. Research has shown that the experience in this event helps to reshape the perception of the game culture, which eventually will lead to the extended meanings of game culture. It can also be seen that the game-making event serves as an educational platform for building the next generation competencies.

Metadata is data about data that is used to mange data itself. As applications based on DBMS are increased, it is suggested that metadata model and metadata interchange model to manage metadata in DBMS. but metadata which is in the form of XML (eXtensible Markup Language) document is generally stored into RDBMS. Therefore In this paper, as for the method to store metadata of RDBMS into OODBMS, we design metadata model, metadata interchange model and implement new repository system. The metadata of RDBMS is translated into in the form of XML Document and integrated into XML Data Server on OODBMS, eXcelon and executes retrieval metadata information about RDBMS by XQL(XML Query Language). So It is possible to searchm edit a metadata. The metadata of XML documents stored in eXcelon is easily made to be printed in web browser by applying a XSL (extensible StyleSheets Language). So we can have a detail information about property of metadata in DBMS.

본 논문은 문서 영상에 존재하는 개별 단어들에 대한 속성정보 추출 방법을 제안한다. 단어 단위의 속성 인식은 단어 영상 매칭의 정확도 및 속도 개선, OCR 시스템에서 인식률 향상, 문서의 재생산 등 다양한 응용 가치를 찾을 수 있으며, 메타정보(meta-information) 추출을 통해 영상 검색(image retrieval)이나 요약(summary) 생성 등에 활용할 수 있다. 제안하는 시스템에서 고려하는 단어 영상의 속성은 언어의 종류(한글, 영문), 스타일(볼드, 이탤릭, 보통, 밑줄), 문자 크기(10, 12, 14 포인트), 문자 개수 (한글: 2, 3, 4, 5, 영문: 4, 5, 6, 7, 8, 9, 10), 서체(명조, 고딕)의 다섯 가지 정보이다. 속성 인식을 위한 특징은, 언어 종류 인식에 2개, 스타일 인식에 3개, 문자 크기와 개수는 각각 1개, 한글 서체 인식은 1개, 영문 서체 인식은 2개를 사용한다. 분류기는 신경망, 2차형 판별함수(QDF), 선형 판별함수(LDF)를 계층적으로 구성한다. 다섯 가지 속성이 조합된 26,400개의 단어 영상을 사용한 실험을 통해, 제안된 방법이 소수의 특징만으로도 우수한 속성 인식 성능을 보임을 입증하였다.

The purpose of this study is to design semantic web and policy direction for national knowledge and information management. The paper describes all the components needed to accomplish the objective: 1) creating unchangeable and unique identifiers for metadata elements, resources, and ontology classes and properties; 2) recommending active use of XML namespaces; 3) establishing metadata and application profile standards for national integrated searching; 4)developing a metadata registry to promote semantic interoperability among metadata; 5) discussing the need of creating ontologies using W3C OWL and ISO Topic Maps; 6) providing intelligent search services based on metadata; and 7) presenting future directions and tasks of national knowledge and information management.

The Semantic Web is a new technology that attempts to achieve effective retrieval, automation, integration, and reuse of web resources by constructing knowledge bases that are composed of machine-readable definitions and associations of resources that express the relationships among them. To have this kind of Semantic Web in place, it is necessary to have the following infrastructures: capability to assign unchangeable and unique identifier (URI) to each resource, adoption of XML namespace concept to prevent collision of element and attribute names defined by various institutions, widespread use of RDF to describe resources so that diverse metadata can be interoperable, use of RDF schema to define the meaning of metadata elements and the relationships among them, adoption of DAML+OIL that is built upon RDF(S) to increase reasoning capability and expressive power, and finally adoption of OWL that is built upon DAML+OIL by removing unnecessary constructors and adding new ones based on experience of using DAML+OIL. The purpose of this study is to describe the central concepts and technologies related to the Semantic Web and to discuss the benefits of metadata interoperability based on XML/RDF schemas and the potential applications of diverse ontologies.
