  • 웹은 지금까지의 문자 위주의 응용에서 벗어나, 그림, 동영상과 같은 멀티미디어 자료를 브라우저를 통해 접근할 수 있도록 하여, 점차 많은 응용분야에서 사용되고 있다. 최근에 들어서는 데이타베이스와 웹의 연동을 통해, 보다 다양하고, 양질의 웹 서비스를 지원하고자 하는 노력으로, 많은 연구자들이 웹 통로에 대한 많은 연구로 좋은 결과를 내고 있다. 그러나 웹과 데이타베이스의 연동에 있어 필요한 웹 트랜잭션 처리시 발생하는 문제에 있어서는 아직까지 만족할 만한 연구결과가 제시되지 않고 있다.본 논문에서는 웹 통로에서 웹 트랜잭션 처리를 위한 시스템인 WebTP를 제안하고, 이를 구현하였다. WebTP는 워크, 워크-전역변수 등을 도입하여, 웹 응용 단위에서의 저장점 설치와 부분 철회와 트랜잭션 상태 관리 기법을 제공하여, 시스템의 가용성과 안정성을 높이며, 구조적인 웹 응용작성이 가능토록 하여, 복잡한 웹 응용 개발을 돕는다.Abstract Enabling users to access multi-media data like images and motion pictures, in addition to the traditional text-based data, Web becomes a popular platform for various applications. Recently, many researchers have paid a large amount of works on integrating Web and databases to improve the quality of Web services, and have produced many noticeable results on this area. However, no enough research results have been presented on processing Web transactions that are essential in integrating Web and databases.In this paper, we have designed and implemented WebTP, which is a Web transaction processing system for Web gateways to databases. WebTP, by introducing work and work-global-variables, provides a more robust state management, supports application-level savepoints and partial rollbacks. It also nhances productity by providing a modular way to develop Web applications.

  • Web Applications are rapidly increasing and the structure becomes very complicated. However, when users explore such complex Web applications, they cannot often grasp the current location and get the information that they want. Therefore, a novel approach to model the navigation of Web application contents is required. In this study, a framework has been presented for modeling adaptive context-based contents navigation of Web applications. The framework performs activities including navigation analysis, navigation design, and navigation realization. first, in navigation analysis domain is analyzed by using use case, focusing on navigation. Next, in navigation design three models have been produced: a navigation information model, a profile, and a navigation interface model. Finally, in navigation realization a Webpage navigation model and a component navigation model have been produced. In this work, several formal definitions and rules for checking validity of navigation model have also been provided.

  • Incorporating proprietary existing it solutions like legacy systems or vendor specific with new technologies is an expensive and time consuming task. Such situations take place due to the lack of ability of proprietary software to cooperate with other parties or to cooperation only with specific vendor products. Such a situation is undesirable and causes a prolonged adaptation period for new applications. This thesis is to show the new approach to creation of Internet applications in Service Oriented Architecture through loose coupling, introduces fare more flexibility into a system composed of connected applications. This approach allows one to integrate through XML based Web Service and reuse a number of arbitrary services available over the Internet in a complex processes specified as a workflow model.

  • Korea-China with the fastest speed Internet Broad Band, has achieved many progresses on Internet shopping. Especially, Korea has made a great effort on comparison website construction. A research prototype design and exploratory analysis are presented to assess success factors and impacts of Korea and China price comparison websites. For different user groups, the relationships between the characteristics of technology and tasks, usage, and organizational impacts were analysed. It shows us how to improve the applicability of fit-viability of the price comparison web sites in China after analysis. These results indicate a need for simple but highly functional price comparison applications. And we designed a sample model to include an interactive web service system for price comparison sites that complement existing information systems. This paper provides a basis for further research aiming to improve the design and management of business applications based on emerging technologies of web service and browser for information management.

  • Driven by the growth of the Internet and the increasing ubiquity of embedded computing systems, the embedded system is exploding in terms of it proliferation of products and the number of complex applications. Intelligent dedicated systems and appliances used in interface, monitoring, communications, and control applications increasingly demand the services of a sophisticated, state-of-the-art operating system. In the case of industrial controller, it is required to use a real-time operating system (RTOS) as a good building block to enable Internet connectivity. However, commercial RTOSes are increasingly less desirable due to their lack of standardization and their inability to keep pace with the rapid evolution of technology. In order to overcome these problems, we consider using embedded Linux and embedded web server. Availability of source code, reduced licensing, reliability, open source community support, as well as others, are key reasons for the use of embedded linux by embedded developers. In this paper, we develop embedded linux platform to control the industrial inverter with the Internet connecting feature. The method of web-based management is also proposed by using the embedded web server and Java applet. We show the feasibility of remote management for the commercial inverter controller with the proposed three-tier web-based remote management system.
