XML is being watched with keen interest for the communication and saving of information. Information represented in XML provides more accuracy and a higher-speed of reference after the process of being implication. But, it is difficult that XML document is exchanged or shared in different area such as electronic commerce or digital library. Because, XML document is being different in syntax but similar in logic, with using structured difference analysis. In this thesis, we converted object-oriented class diagram to XML DTD and designed an index mechanism based on the structure information for the converted XML DTD. With our methods, we could effectively and lastly retrieve the specific element and respect to usefully access element by simple operations.

본 연구팀에 개발한 UML 그래픽 편집 도구를 이용하여서 소프트웨어를 개발하는 과정에서 발생하는 설계 정보는 모델 관련 정보와 뷰에 관한 정보들을 데이터베이스에 저장 관리된다. 이들을 Web 통해서 UML 설계 정보의 관리와 공유하기 위해서 UML 설계 정보를 미리 정의한 XML DTD를 이용하여 XML 파일로 변환한 후에 이를 개발자와 개발 도구들간에 교환하여 공유한다. 본 논문에서는 정의한 UDXF DTD를 이용하여서 UML 설계 정보를 XML 파일 형태로 변환한 후에 UML 설계 정보를 웹 기반의 분산 환경에서 공유하기 위한 설계정보 저장소에 관한 연구이다.

사업 영역 확대와 네트워크 발달로 인해 전자상거래(Electronic Commerce)는 점차 국제적 환경으로 확대되고 있으며, 장소나 시간에 구애받지 알고 정보를 전송할 수 있게 되었다. 거래되는 업무가 증가됨에 따라 거래내용, 결제 내용(계좌번호, 카드번호 등), 비밀번호 등 교환되는 정보의 종류도 다양해져 보안의 중요성이 대두되었다. 이에 데이터 사용 효율과 응용 가능성을 높이기 위해 차세대 인터넷 표준으로 대두되고 있는 XML을 메시지 처리 단위로 정의하고, XML 기반의 인터넷 메시징 시스템인 IMSX (Internet Messaging System based on XML)을 설계하였으며, 보안 위협으로부터 대응하기 위해 암호화(Encryption)와 전자서명(Digital Signature) 등의 메시지 레벨의 응용 보안을 적용하였다. 또한 문서 송신, 문서 수신, 검색, 문서 변환, 템플릿(Template) 제공, 보안 서비스 등을 선정하여 구현하였다.

This paper presents the development of gateway for smart grid for the interoperable communication between IEC 61850 station leveled devices and one of legacy Modbus, DNP3, and IEC60870-5-101/104/103 communication protocol devices of bay level in substation or for the exchange of information between IEC 61850 substation and SCADA control center. The data-mapping model is designed for the exchange of information and the gateway configuration tool is developed for generating meta-data based on XML Schema. this paper is mostly concerned with the design and realization of gateway system for the interoperable data communication between a legacy protocol device and IEC61850 based devices or systems.

In this paper, autonomous information exchange methodology is studied between IEDS using SOAP protocol based on XML and PtP communication. Inference-based solution of the IED identifies the faulted zone autonomously from free information exchange among IEDs, transmits the operation information to the above SCADA system, also determines whether it executes or not for commands from the above SCADA. Finally, Inference-based solution is implemented using MS Visual C++ MFC, MS SOAP and MS XML. Availability and accuracy of the design is verified from simulation reviews for typical distribution substation.

A mobile computing environment has many difference in character from conventional communication over wired network. These include very presents distributed design system based the mobile agent for mobile computing environment. To integrate design resource, we presented ISA(Integration Service Agent, which allows a designer to build integrated application using distributed resources, and to collaborative by exchanging service. Also we propose ICM(XML based Intelligent Connection Manger) using mobile agent. And suggested new intelligent data and process transfer architecture using ICM to implement an agent based design system in mobile environment.

This paper presents the method that allows easy and rapid integration of legacy resources within the company and between departments. The proposed system can easily construct a distributed environment for collaborative design between departments in the companies. It supports knowledge-based integration system, which allows designers to develop product with deep knowledge about product design. For the purpose, DOME (Distributed Object-based Modeling Environment)-which has been developed through various studies-was used in this paper. To overcome its problems and insufficiency, the Web-Integrator is proposed. The Web-Integrator is very suitable for an Internet environment because it uses HTTP (Hyper Text Transfer Protocol) and XML (extensible Markup Language) as its main communication method. By supporting the remote object access via URL (Uniform Resource Locator), the implementation of the integrated system makes the Web-Integrator systematic and intuitive. All the functions and resources provided by DOME could be used with the interface that enables bi-directional communication with the DOME system. Web-Integrator provides full web-based environments for the general designers, who do not have a full design knowledge and experience, and the proposed system allows design operations to happen at any place and anytime. Also it provides XML-RPC(Remote Procedure Call) based web service framework, which allows other systems to use easily the service that the DOME system supplies regardless the location and the platform.

In this thesis. we present the cyber lecture system based on XML that uses the communication network as the 100Mbps LAN. The system was designed to analysis the existing cyber lecture system and its details arid to examine web system architecture and XML 3-tier model The result of the study consists of he cyber lecture system based on XML developed on 100Mbps LAN to improve method of the cyber lecture system by using ma 3-tier model arid utilisation of web interface to offer handiness of the cyber lecture system.
