In this study, we suggest the effective storage structure and management method for XML-based electrocardiography(ECG) data to support the interoperability between medical information systems, and implement the metadata system of ECG data providing the web-based information service. ECG matadata management system include functions for storing and managing as well as reporting PDF service of ECG data. We analyzed a characteristics of the data and access patterns for XML-based ECG and then used the non-partitioning storing method and indexing the extracted metadata from the HL7 aECC for supporting the quick search. We, using the template mechanism, converts the XML-based results data into various formats in order to provide services of the ECG reporting.

SAML(Security Assertion Markup Language)은 웹 서비스 환경에 최적화된 인중과 권한 부여를 표준적이면서도 확장성 있는 구조를 제공하는 공개된 표준이다. ebXML과 같은 공개된 XML 기반 거래 프레임워크에 SAML을 적용함으로써 기업 간 협력형 비즈니스 모델 내어서 문제가 되었던 550(Single Sign-on)를 위한 사용자 관리 및 인증의 부담을 최소화 할 수 있다 본 연구에서는 SAML에 대한 기술 분석과 함께 ebXML 및 웹 서비스 비즈니스 트랜잭션 내에서 적용 방안을 논의하고 원 서비스 모델 기반의 SAML 인증 시스템을 제시한다.

Web Service which consists of SOAP, WSDL and UDDI is a software system that enables interactions of heterogeneous systems on networks with standardized XML message. Especially, UDDI is a registry for supporting the registration of a service by service publisher and discovery of a service by service requester. The preliminary studies are just about publishing and searching services. It presents the researches about UDDI study for improvement of searching a service and extended UDDI design for improvement of reusability with service components aspects. In this paper, we suggest not only features about publishing and searching services of existing UDDI system but also novel UDDI data structures and API for a reusable service model. In addition, we design and implement an extended UDDI system for publishing and finding the reusable services. Therefore, by using proposed UDDI systems, service developers reduce development costs and time through developing a service application reusing the already implemented services. In addition, it can expect to ensure the quality of services by reusing the proven services.

KORMARC used in library bibliographic information, had been pointed several weaknesses such as inflexibility lack of link information and compatibility. In addition, a sudden increase in digital information associated with development of internet is demanding an integration of web resources metadata as the resource of library information. This study mentioned XML/KORAMARC system or adaption of XML standard format turned out to be the most efficient way to use KORMARC formats and to expand the range of those information service such as bibliographic information, factual information, referral information and full-text.

Recently the computing environment has been moved to open architectures that include Web technologies. Web Service is one of import component of the new paradigm. This paper presents a design and implementation of GIS Web Service for mobile devices. As many mobile devices are equipped with GPS (Global Positioning System), it is required to handle the position information more effectively. We have extended the proxy program in the client device to actively send the context information to the server. Based on the context information the server determines the optimal service mode to a particular client. A working example of location?based GIS Web Service is also presented. By using Web Service standards and XML messages we can achieve the maximal interoperability for heterogeneous mobile devices.

While the existing Web focuses on the interface with human users based on HTML, the next generation Web will focus on the interaction among software agents by using XML and XML-based standards and technologies. The inference engine, which will serve as brains of software agents in the next generation Web, should thoroughly understand the Semantic Web, the standard language of the next generation Web. As abasis for the service, the W3C (World Wide Web Consortium) has recommended SWRL (Semantic Web Rule Language) which had been made by compounding OWL (Web Ontology Language) and RuleML (Rule Markup Language). In this research, we develop a backward chaining inference engine SMART-B (SeMantic web Agent Reasoning Tools -Backward chaining inference engine), which uses SWRL and OWL to represent rules and facts respectively. We analyze the requirements for the SWRL-based backward chaining inference and design analgorithm for the backward chaining inference which reflects the traditional backward chaining inference algorithm and the requirements of the next generation Semantic Web. We also implement the backward chaining inference engine and the administrative tools for fact and rule bases into Java components to insure the independence and portability among different platforms under the environment of Ubiquitous Computing.

The study proposes component models in developing an efficient platform for internet-based structural analysis. Since a structural analysis requires an operation of complicated algorithms, a client-side computation using X-Internet is preferred to a server-side computation to provide a flexible service for multi-users. To compete with the user-friendly interfaces of available commercial analysis programs, a window-based interface using Smart Client was applied. Also, component-based programming was performed with the considerations on reusability and expandability so that active Preparation for future change or modification could be feasible. The components describe the whole system by subdivision and simplification. In the relationship between upper-and lower-level components and also in the relationship between components and objects, a unified interface was used to clearly classify the connection between the libraries. By performing data communication between different types of platforms using XML WebService, a conner-stone of data transfer is proposed for the future integrated CAE. The efficiency of the developed platform has been examined through a sample structural analysis and design on planar truss structures.

본 논문에서는 XML Page로부터 닷넷 모바일 Web Page로의 변환 기능을 제공하는 웹서비스 프로바이더를 설계ㆍ구현하였다. 웹서비스 프로바이더는 플랫폼과 프로그래밍언어의 제약 없이 누구나 사용 가능하다는 장점을 가지고 있다. 본 논문에서 구현한 웹서비스 프로바이더로 제공하는 변환 라이브러리는 어휘분석기 모들과 구문 지향 번역기 모듈로 구성되어 있다. 어휘분석기 모들은 XML Page를 입력받아 각 태그들을 분석하고 토큰을 출력한다. 구문 지향 번역기 모듈은 어휘분석기에서 출력된 토큰들을 입력받아 문법을 체크하고, Parsing이 완료되면 대응되는 모바일 .NET 컨트롤로 변환하여 최종적인 닷넷 모바일 Web Page를 생성한다. 어휘분석기 모듈과 구문 지향 번역기 모들은 각각 어휘분석기 생성기(LEX)와 파서 생성기(YACC)를 사용하여 구현하였다. LEX와 YACC의 사용은 태그를 확장할 경우 변경된 부분만 설계함으로써 유연하게 대처할 수 있는 장점을 가지고 있다.

Recently, many kinds of XML based application services are widely used in internet. And the markets for mathml editor are needed for the technology combined with other text editor. We are developing a system for MathML based browser and editor for the service of internet application. MathML based browser is applicable for e-book service and many kinds of document system. This system is composed of document editing module and displaying processing module. This system is useful for the processing of MathML tag by unexperienced users with MathML syntax. Users can edit the math tag's document with ease and efficiently. Based on XML, many parser functions are optimized for the speed of document processing. This system can afford to the development of internet world.
