  • The internet is comprised of various users with diverse hardware and software platforms. This paper presents a tourism information system which enables the stable and reliable transmission of information over the dispersed, heterogeneous, and/or mobile platforms. The proposed system assumes XML as the basic document format since it has been accepted by W3C as the standard for information exchange on the internet This paper exploits the characteristics of JAVA and XML as they provide software applications independent of the platforms. The proposed system also deploys Aglet, a mobile agent developed by IBM, to ensure a dynamic and flexible performance of the system over the internet. The system provides the user oriented search and retrieval of tourism information, and also enables the reservation of various services and facilities with mobile devices.

  • XML is situating a standard fur data exchange in the Web. Most applications use database to manage XML documents of high-capacity efficiently. Therefore, most applications create label that expresses structure information of XML data and stores with information of XML document. A number of labeling schemes have been designed to label the element nodes such that the relationships between nodes can be easily determined by comparing their labels. With the increased popularity of XML data on the web, finding a labeling scheme that is able to support order-sensitive queries in the presence of dynamic updates becomes urgent. XML documents that most applications use have many properties as their application. So, in the thesis, we present the most efficient updating methods dependent on properties of XML documents in practical application by choosing a representative labeling method and applying these properties. The result of our test is based on XML data management system, so it expect not only used directly in practical application, but a standard to select the most proper methods for environment of application to develop a new exclusive XML database or use XML.

  • In this paper, new voice message system supporting massive outbound call is proposed. Basic idea of the proposed system is to pre-process all the text-to-speech conversion process, mixing of text and attached music file and to store the results of pre-process in the cache server which is connected to the IVR. New voice message system is optimized for the voice message system supporting massive outbound call by distributing the load of the web server caused by server-side script implementation which is accessing database and generating dynamic Voice XML document over client module and server module of web server. The proposed voice message system was test-deployed in one domestic voice message application service provider and it is shown that proposed voice message system reduced the response latency problem of test-bed voice message system.

  • 현재 유선에서 지원되는 웹 컨텐츠를 개인용 단말기에서 지원하기에는 단말기의 성능상 한계(screen size, memory size, bandwidth 등) 때문에 여러 가지 문제가 있다. 트랜스코딩이란 이러한 기존 유선 환경에서 제공되는 웹 컨텐츠를 특정 환경에 적합한 형태로 변환 하는 것을 의미한다. 그러나 이와 관련된 기존 연구에서는 사용자가 요구하는 사항만을 변환 하거나 서비스 제공자가 일방적으로 변환하여 웹 컨텐츠를 제공하고 있어 이슈변화에 따른 사용자의 대처능력이 떨어지고 사용자의 사용성이 저하되며, 사용자에게 무의미한 정보 제공의 가능성이 있다. 이러한 문제점들을 해결하기 위해 본 논문에서는 멀티미디어 뉴스 제작을 위한 표준인 NewsML을 대상으로 사용자의 동적 프로파일과 서비스제공자의 어노테이션을 이용하여 사용자가 요구하는 기사와 서비스 제공자가 제공하는 기사를 같이 변환하는 기법을 제안한다. 본 논문의 결과 갑자기 발생하는 사회적 이슈변화에 따른 사용자의 대처능력이 향상 되고 사용자가 불필요한 정보에 과다하게 노출되는 것을 막을 수 있다.

  • 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.

  • BPEL is a standard workflow language, which interacts with Web Services and is used in various applications. But it is difficult to use BPEL for specific applications which require additional functions. In this paper, we present a system which can add new functions to BPEL based on an aspect-oriented programming (AOP) technique. In order to add new functions to BPEL, we define a JWX document format that can describe new functions to apply to BPEL. JWX is XML-oriented document that can code the corresponding Java program in order to dynamically add new functions to BPEL documents. It is possible for BPEL workflow to add new functions without modifying the existing programs using the AOP technique, which guarantees low degree of coupling between key and additional requirements. Additionally this systems weaves based on new functions of Java program and JWX document by expanding BPEL engine called B2J based on AOP and execute them. Therefore it is possible to develop a new BPEL engine with additional functions easily and with low cost. The new system can execute additional conditions that the current BPEL engine doesn’t provide. The new system using functions of BPEL supplied by B2J. The new system can be used to add a new rule engine, which isn't currently provided.

  • Web contents created for desktop screens give rise to problems when they are to be displayed on the small screens of mobile terminals. While in some cases some of the objects of a page may not be displayable due to the lack of browser capability, the entire page may not be displayable due to the incompatibility with the browser in other cases. In this paper, we introduce a new mobile content adaptation approach based on web clipping, which transforms an original page into one that is optimally displayed on a mobile terminal. In this method, a source page is automatically clipped and transformed according to the clip specification made by the content provider using a clip editing tool. The clip editing tool allows the user to specify group clips, multi-level cups and dynamic clips as well as simple clips, and the presentation layout through a graphic user interface. Based on the clip specifications, each clip is transformed into an intermediate meta-language document, which in turn is transformed into a presentation page in the target markup language. Transcoding of image objects in major image file formats is also supported.
