In a pervasive environment, there are various applications as much as connections of various devices. In this computing environment, XML is the most suitable data representation method. XML is able to transform data for other application areas using XSLT. XML is text-based, the file size of XML document is bigger than binary data file. Therefore, XML has a disadvantage that it is hard to deal with XML in a pervasive environment. In this paper, we survey encoding methods of XML documents, and then we propose a transform method that transforms an encoded EXI format XML document into an EXI format XML document suited for other applications. Among various applications, we present a system that transforms an EXI format XHTML document into an VoiceXML document. This system can improve reusability of EXI format XML documents in a pervasive environment and it is expected to contributes utilization of EXI format XML documents.

There are POP3(Post Office Progocol 3) and IMAP4(Internet Message Access Protocol 4) for E-Mail service of wire Internet For mobile e-mail service that use wireless Internet, must use exclusive use mobile e-mail server in the case of POP3 e-mail or flow e-mail conversion and because e-mail is kept in sever side with remote file server in case of IMAP4 mail that is used by Web-Mail, utilization of mobile e-mail service is difficult by mobile client who there is no IMAP4 rules. This thesis embodying e-mail extraction engine for mobile that do to design markup language converter of XML base, and use Web-Mail of recently been generalizing IMAP4 base in mobile, presented mobile e-mail service method to do so that can use Web-Mail that is based on IMAP4 as well as POP3 mail service in mobile environment.

문서의 논리적 구조를 기술하는 표준 메타 언어인 SGML은 각종 전자문서를 기술하는 기반 언어로 사용되고 있으나 그 사용법이 매우 복잡하다. 그리고 이 SGML로 정의도니 HTML은 그 사용법이 매우 쉬워 홈페이지 제작등에 널리 사용되고 있다. 그러나 태그의 확장성이 없고, 사용자가 마음대로 DTD를 바꿀수 없어 다양한 형식의 문서를 표현하는 데는 한계가 있다. 따라서, 최근에 다양한 인터넷 문서를 다룰 수 있도록 XML 이라는 확장 가능한 마크업을 기술할 수 있는 새로운 메타 언어가 출현하게 되었다. 그런데 기존에 만들어진 SGML문서들을 새로운 웹 환경에서 사용하기 위해서는 이 문서들을 XML 문서로 변환하는 작업이 필요하다. 본 논문은 기존에 만들어진 SGML 문서의 DTD를 웹 환경에서도 사용할 수 있도록 XML DTD로 자동 변환하는 시스템을 설계하여 자바 언어로 구현한 내용을 기술한다.

CBD(Component-Based Development)에 있어 컴포넌트 시스템은 잘 정의된 아키텍처를 기반으로 개선되어야 한다. 컴포넌트 시스템의 아키텍처를 정확하고 엄밀하게 설계. 분석하기 위해서는 아키텍처 기술 언어(ADL)의 사용이 필요하다. 아키텍처 모델링에 ADL을 효과적으로 사용하기 위해서는 ADL로 기술된 아키텍처 모델을 효율적으로 분석, 처리 관리할 수 있는 지원 환경이 필수적이다. 본 논문에서는 ADL 모뎀 지원 환경 시스템의 구조를 기술하고 본 연구팀에서 개발 중인 ADL 모델 관리기의 구조를 기술한다. ADL 모델 관리기 중 ADL 모델 정보들을 XML 형태로 저장, 관리하기 위한 XML 기반 ADL 모델 변환기의 구조를 기술하며 ADL-XML 변환 방법을 설명하고 그 변환 결과를 보여준다.

In this paper, we designed and implemented the general-purpose document repository manager for the ebXML-based e-business framework that support the rapid translation of various types of documents and provide the flexibility corresponding to the framework changes. Also, we automated the manually-processed e-business document translation process by designing the adaptor module for the interoperability of legacy systems. In the regards, our designed general purpose document manager makes it possible to integrate the existing e-commerce systems that are operated on the heterogeneous frameworks, and can be used on global e-business solution.

현재 무선 인터넷 컨텐츠는 유선 컨텐츠와 호환이 되지 않으며 다양한 종류의 무선 마크업 언어들로 구성되어 있어 무선 컨텐츠를 재구축해야 하는 문제점이 있다. 본 논문에서는 이를 해결하기 위해 유선 컨텐츠를 재사용하는 방안으로 XML 기반의 유무선 컨덴츠 변환기를 설계한다. 컨텐츠 변환의 중간 표준포맷으로 XML 문서를 생성하므로 새로운 언어로의 변환을 고려할 때 해당 프리젠테이션 변환모듈만 추가시키면 확장 가능하므로 유지보수가 쉽고 효율적인 변환이 가능하다. 따라서 새로운 표준과 기술 변화에 대응이 용이하며 또한 유선 컨텐츠의 재사용으로 인해 개발비용이 절감되고 개발기간이 단축되므로 빠른 무선 인터넷 시장 진입이 가능해진다.

In the distributed environment based on the network, we can get the necessary information by sharing or exchanging an information document. However, there is the difficulty for sharing and distributing of the information document because of the heterogeneity at the dist(equation omitted). In this paper, we propose(equation omitted) interchange structure based on CORBA for disposing of the information document and provide the mechanism for interchanging IDL to DTD by designing the converter within it.

Advances in communications and control technology, the strengthening of the Internet, and the growing recognition of the urgency to reduce the risk and production cost are motivating the development of improvements in the traditional manufacturing industry. In this paper, we developed a remote dust collector bag control system which is a combination of advanced IT and traditional dust collector based on the event. At first, we made the A/D(Analog/Digital) converter using a micro processor because the differential pressure transmission, which is a sensor of the dust collector, produces analog volt data. A/D converter can provide RS-232 communication to connect with Power Line Communication(PLC) modem. And, n-bytes message format was defined for the efficient dust collector bag information transmission from a dust collector to a user. Also, we designed the data types to model the dust collector and the dust collector bag, and they were logically modeled using XML and object-oriented modeling method. In addition to that, we implemented the system for showing the dust collector bag exchange time exactly to users at real-time using various visual user interfaces.

XML-based standards such as CCD(Continuity of Care Document) and CCR(Continuity of Care Record) have been developed for representation, integration, and exchange of personal health record(PHR), and various of researches on PHR based on the standards have been conducted. These researches have developed and used CCD/CCR parsers each with their own different ways, but it can be hard to develop and update the parsers because of the structural complexity of the standards. Moreover, inter-exchange between CCD and CCR documents in the PHR-related medical information systems should be possible for the interoperability of the systems. Therefore, we proposed a designing method to develop the tools treating XML-based CCD/CCR documents. And we implemented CCD/CCR parser based on the proposed method and developed a converter from CCD to CCR using the parsers. To confirm the usefulness of the developed tool, we performed an experiment of creating CCD documents using the personal health data gathered from chronically ill patients in Kyungpook National University Hospital and of converting from the CCD documents to CCR documents.

According to development of Information Technology and generalization of internet, practical use field of geography information became various. Therefor various Geographic Information System (GIS) constructed to manage geography information efficiently. However, geography information data of various form is depending on graphic authorizing tool of various form being not normalized each other. So, OGC(Open Geospatial Consortium) proposed GML(Geography Markup Language) that describe normalized geography information data that can apply mutually and W3C proposed SVG(Scalable Vector Graphics) of vector base. In this paper creates GML data of XML base for geography information data processing to vector graphic object, and design and implementation of GML document editing and translation system that define code converter that create GML document through created graphic objects and change vector graphic to logic structure of XML base.
