To access massive and various HTML documents that are in the web using wireless Internet equipments, another WML document that is equal to the HTML document must be written, In the case Web documents written by HTML are massive, the construction of a WML site with the same information needs much cost of space and time, This paper designs and implements the HTML-XML converter that alleviates such a problem. The HTML-WML converter translates the Web document written by HTML to the WML document for portable wireless equipments, The HTML-XML converter has advantages that it reconstructs WML document dynamically according to portable wireless equipments and processes various image formats such as GIF, JPG, BMP, and so on, The HTML-WML converter can be used as not only a utility of the WML editor but also a real-time converter on wireless Internet.

BPEL is used in various domains since it can describe the flow of works according to conditions and rules, and it can call web services in service-oriented computing environments. However, new functions that are not provided by BPEL grammar are required in specific domains. Generally, when new functions are required, the domain-specific language should be newly defined and developed, which requires high development cost. In this regard, a new function needs to be defined and added instead of developing domain-specific language with the new functions added. However, such methods only allow an addition of a single function, and it is difficult to design and add new functions according to the needs. This paper defines XAS4B document, which extends the BPEL grammar function through XML schema in order to add new functions, and proposes BPEL engine generator that generates BPEL engine with the new functions added by processing the document. The XAS4B document enables the creation of a new grammar added to BPEL using XML schema. It also shows the process of adding new functions to BPEL engine using AspectJ, JAVA implementation of aspect-oriented programming. The proposed system can add new functions using AspectJ without modifying BPEL engine. This allows the provision of new functions at low cost in various domains.

A standard Web server or web application servers require the Web Servlet container to execute SOAP messages. But it requires additional process to make web service modules and need communication port. Also, Recently many web applications is becoming increasingly demand against the dynamic document than the static documnet. But a recent study has found that Apache Web Server always does not show the better performance. The more it have the dynamic documents, rather it can show worse performance. To solve this problem, we propose a new High-Speed Message Processing System, in which the SOAP_MP and the WSDL builder are used. The WSDL builder convert HTML/XML to WSDL files automatically and the SOAP_MP minimize SOAP massage processing time by eliminating the Tomcat Servlet container in the mobile Web Services implementation. We compare and analyze the System, which was proposed by us, with the standard Web Service system.

In order to provide customized services according to a specific user or environment, various service scenarios should be developed based on context-aware workflow model. As the context-aware workflow model is constructed using limited context information and service information in the service domain, overlapping elements can occur in many service scenarios. The repetitive work process that results from these overlapping elements delays the development process of the service scenario. Therefore, the elements of the context-aware workflow model must be reused to solve the unnecessary work processes of service scenario development. In this paper, we propose a reuse method XML Object in context-aware workflow model to improve the process of service scenario development. The proposed method documents and manages the independent XML Object of the context-aware workflow model and reuses it by invoking the unit document in the service scenario development process. It can also be applied to new service scenarios by changing the attribute values of reusable elements. Experiments show example that the development process of the service scenario is simplified by reusing the elements of the context-aware workflow model.

The service that has recently come into the spotlight utilizes the map to first approach the map and then provide various mash-up formed results through the interface. This service can provide precise information to the users but the map is barely reusable. The sketch-map system of this paper, unlike the existing large map system, uses the method of presenting the specific spot and route in XML document and then clustering among sketch-maps. The map service system is designed to show the optimum route to the destination in a simple outline map. It is done by renovating the spot presented by the map into optimum contents. This service system, through the process of analyzing, splitting and clustering of the sketch-map's XML document input, creates a valid form of a sketch-map. It uses the LCS(Longest Common Subsequence) algorithm for splitting and merging sketch-map in the process of query. In addition, the simulation of this system's expected effects is provided. It shows how the maps that share information and knowledge assemble to form a large map and thus presents the system's ability and role as a new research portal.

Managing GML data in traditional database systems is not efficient since It has not only characteristics of spatial data but also features of (semi) structured n documents. XML enabled database systems can manage U data efficiently, however they cannot handle spatial data. Spatial database systems are good at spatial data handling but those are inefficient for XML data. This paper proposes a storage method of GML data for spatial database systems in order to solve the problems. The proposed method generates spatial database schemas from GML application schemas and store GML data into SDBMS through the generated schemas. A prototype of the storage method has been implemented on the Postgre SQ/SPE system to show the proposed method is appropriate for storing GML data. As a result, the implemented system was able to store various GML data which had diverse XML structures and different size. Stored data size was smaller than GML files. Furthermore, spatial, non-spatial, and mixed content queries could be performed over the stored GML data as quickly.

현재 다양한 패러다임의 수많은 프로그래밍 언어가 존재하고 있으며, 각각의 프로그래밍 언어를 실습하려면 해석기(interpreter)나 컴파일러(compiler) 같은 언어처리기를 갖추는 것이 필요하다. 언어처리기를 개별적으로 갖추는 것은 설치에 대한 시간적 부담, 시스템 자원 낭비 업그레이드의 필요성 등으로 인해서 언어 학습과 직접적인 관련이 없는 부분에 대한 부담이 커진다. 본 논문에서는 WWW 환경에서 프로그래밍 언어를 실습할 수 있는 시스템을 구축하였다. 실습하는 프로그래밍 언어는 특정 서버에 제한적이지 않고, 네트워크를 통한 분산환경에서 확장이 용이하다. 또한 실습환경을 설정하는 구성 파일은 구조화된 문서의 작성을 지원하는 XML을 이용하여 관리자가 쉽게 구성파일을 작성할 수 있도록 했고, 자바의 정책(policy)파일을 이용해 시스템 자원 사용 허가를 투명하게 했다.
