XML은 어떠한 정보든지 구조화할 수 있으며, 데이터와 스타일 정보를 철저히 분리함으로써 컴퓨터가 처리할 수 있는 메타데이터를 제공하여 정보검색의 정확성을 높이는 획기적인 계기를 마련하였다. XML 데이터와 스타일의 분리를 위해 XML 기반의 문서를 표현하기 위한 스타일시트인 XSLT가 제안되었지만, 이는 전문적인 지식이 없는 일반인이 사용하기에 매우 어려울 뿐만 아니라, 작성하는데도 많은 시간과 비용이 필요하다. 이에 대한 대안으로 현재 XSLT 문서 편집 시스템이 상용화되어 출시되고 있지만. 사용이 너무 복잡하고 어려워 문서 편집 시스템의 요구조건을 충족하기에는 미흡하다. 이에 본 논문에서는 일반인도 쉽게 XML 기반의 문서 구조와 스타일시트를 생성할 수 있는 시각적 환경 기반의 XMㄴ 기반 문서 편집 시스템을 구현하고, 이를 실제 적용하여 기존 시스템과의 성능 평가를 통해 시스템의 성능을 검증하였다. 또한 문서 구조에 따른 데이터베이스 테이블을 동적으로 생성하여 XML 기반 문서 관리의 효용성을 다각도로 제시하였다.

최근 XML은 다양한 운영체제와 데이터베이스, 여러 응용체계를 포함하는 이질적인 컴퓨팅 환경에서 통합을 위한 표준으로 각광받고 있다. XML은 특히 데이터베이스 시스템, 과일 시스템 등을 포함한 이질적인 형태의 데이터 처리 시스템 사이에서 데이터를 교환하기 위한 각종 표준을 제공하고 있다. 본 논문의 목적은 여러 분야에서 데이터공유를 위한 많은 노력 끝에 제시한 각종 표준 및 지침을 연구하여 통합적인 정보체계의 기반을 구축할 수 있는 통합 프레임워크를 제안하는 것이다. 통합 프레임워크는 다양한 정보 시스템에서 운영, 유지하고 있는 이질적인 데이터를 통합하기 위한 방법으로 XML Registry를 이용하여 메타데이터를 생성하고 이를 참조하여 통합정보체계에서 필요로 하는 공유데이터를 보관, 관리하는 공유 데이터 Repository를 생성한 후 각종 정보를 제공할 수 있는 구조이다.

최근 도메인에 기반한 개념과 이들 개념간의 관계를 설정할 수 있는 온톨로지 기반 컨텍스트 모델들이 유비쿼터스 컴퓨팅 환경에서 연구되고 있다. 그러나 새로운 개념의 추가에 따른 온톨로지 재구성은 시간이나 비용적으로 많은 오버헤드를 초래한다. 즉 하위 레벨에 있는 임의의 데이터 구조가 수정될 때마다 계속 적으로 기존 온톨로지를 변경해야만 한다. 따라서 센서 노드의 동적인 컨텍스트 표현보다 미들웨어와 같은 최상위의 추상적이고 정적인 컨텍스트 표현에 적합하다. 한편 센서 네트워크에서의 베이스 스테이션 기반 상황인지 기법은 상황 조건을 만족시키지 못하는 저수준 센싱 정보를 베이스 스테이션으로 전송하는데 많은 에너지를 소모한다. 본 논문에서는 센서 노드에서의 동적인 컨텍스트의 표현과 저수준 센싱 정보의 전송량을 줄이기 위해 메타데이터와 RDF 기반 구조의 변형인 Triple 구조를 결합한 컨텍스트 모델은 제안한다.

A biological data acquisition based on web has emerged as a powerful tool for allowing scientists to interactively view entries form different databases, and to navigate from one database to another molecular-biology database links. In this paper, the biological conceptual model is constructed hybrid biological data model to represent interesting entities in the data sources to applying navigation rule property for each biological data source based on four biological data integrating layers to control biological data. When some user's requests for application service are occurred, we can get the data from database and data source via web service. In this paper, we propose a query processing model and execution structure based on integrating data layers that can search information on biological data sources.

It has been constantly demanding for effective way to improve software development productivity and automation. In this paper, we did research to configure the component assets to reuse design information from the design phase domains based on the DMI. It is necessary abstracted information architecture of an independent platform development environment to reuse design information on the design stage. Also, It should be based on a well-designed to support the design architecture of the application domain. Therefore, in this paper, I want to use the DMI architecture that can be represented by formal level of architectural design information platform and application domain area. It is able to decomposition architecture asset with the part design information from the design phase composition or a high level of abstraction on DMI. Therefore, the metadata structure of the asset architecture will support a structure which can reuse the structure-based design of the domain areas.

Recently, the development of sensors and the mobile communication device offers a number of possibilities in the medical and related fields. However, this data is generated, it is difficult to match the metadata and standard units. The data integration is required to use the data generated by the different specifications of the sensor efficiently. Accordingly, in this paper we propose a method using an ontology as a method to integrate the data generated by the existing sensors and the new sensor. The ontology is mapping to the standard item and sensors, also include a type and structural difference. The mapping is comprised of two : data mapping, and metadata mapping. There are standard items that are created in this way, type of data exchange between services. This can solve the heterogeneous problem generated by sensors.

The sensor network-based service collects data by using the sensor, the data is aware of the situation via the analysis, and the service provider provides a service suitable for the user via the context-awareness. However, this data is generated, it is difficult to match the metadata and standard units. The data integration is required to use the data generated by the different specifications of the sensor efficiently. Accordingly, in this paper we propose a method using an ontology as a method to integrate the data generated by the existing sensors and the new sensor. The ontology is mapping to the standard item and sensors, also include a type and structural difference. The mapping is comprised of two:data mapping, and metadata mapping. There are standard items that are created in this way, type of data exchange between services. This can solve the heterogeneous problem generated by sensors.

As the non-face-to-face situation continues for a long time due to COVID-19, the underlying technologies of the 4th industrial revolution such as IOT, AR, VR, and big data are affecting the metaverse platform overall. Such changes in the external environment such as society and culture can affect the development of academics, and it is very important to systematically organize existing achievements in preparation for changes. The Korea Educational Research Information Service (RISS) collected data including the 'metaverse platform' in the keyword and used the text mining technique, one of the big data analysis. The collected data were analyzed for word cloud frequency, connection strength between keywords, and semantic network analysis to examine the trends of metaverse platform research. As a result of the study, keywords appeared in the order of 'use', 'digital', 'technology', and 'education' in word cloud analysis. As a result of analyzing the connection strength (N-gram) between keywords, 'Edue→Tech' showed the highest connection strength and a total of three clusters of word chain clusters were derived. Detailed research areas were classified into five areas, including 'digital technology'. Considering the analysis results comprehensively, It seems necessary to discover and discuss more active research topics from the long-term perspective of developing a metaverse platform.

As XML is used by standard format for information expression and information exchange in various field, Many Company began to use SVG by user interface or information expression tool of embedded system such as mobile phone based wireless internet. Because SVG has many additional information to keep structure of SVG document exception real data, there is a problem that transfer time of SVG file is so cost for quantity of transmitted data actually. To solve this problem, many researches using compression conception have been conducted for applying to an embedded system. This paper proposes SMETA that can use existing researches using compression concept at once. SMETA divides SVG file to each part that can allocate meaning, and gives semantic metadata to each part without alteration of SVG structure. SMETA can reduce site of transmitted SVG file actually by transmitting specification part of SVG file that metadata does not agree or has unlisted part in an embedded system between an embedded system and server, before transmit whole SVG file. By size of transmitting SVG file is decreasing, transfer time can be shortened accordingly.

The enterprise system is becoming more complex and larger. With the changes of the times, the system is developing to object-oriented programming method(OOP). However, the same code inserts to the core class repetitiously in the OOP, that causes a decrease in productivity and a trouble of application of another requirement. To solve this weak point, we propose a weaving mechanism what applies to metadata and crosscutting concern. For a class optimization and an integration between different languages, we take the following way. This paper uses three ways, those are, metadata generation using reflection, transformation to Abstract Syntax Tree, and mapping through crosscutting information specified XML. Through the proposed theory, class optimization can be accomplished by solving a functional decentralization and a confusion of codes.
