It is important to integrate an enterprise application for automating of the business profess, which is responded by a flow of market environment. There are two categories of method that integrate enterprise applications. One is Synchronous Integration, and the other is Asynchronous Integration. EAI(Enterprise Application Integration) and Web service which of the asynchronous integration is focused in the automating method of the business process. After we construct the application integration for automating of the business process, we have to concern about managing of the business transaction. Many Organizations have proposed the process method of business transaction based on 2-phase commit protocol. But this method can′t supply the phase that classify the transaction by transaction weight. In this paper, we propose an efficient method of transaction process for business transactions, which is composed by ′Classify Phase′ that classify transactions. We called this model "3-Phase Commit Method Applied by Classify Phase", we design this model to manage an resource of enterprise efficiently. The proposed method is compared by the method based on 2-Phase commit that could be a problem of management the resource of enterprise, and the advantage of this method is certified to propose the solution of that problem.

Web services (WS) present a new promising software technology, which provides application-to-application interaction. They are built on the top of existing web protocol and based on open XML standards. Web services are described using WSDL, and the UDDI is a integration directory provide registry of Web Services descriptions. WSDL provides information of Web Services but it is getting more and more important to know more than those provided by WSDL. From WSDL we can not get the information like usage of WS, performance of WS, complexity of WS, usability of WS with other web service. In this paper, we proposed a new method for Web Services so called Public Web Services Analyzer (PWSA). This technique is based on analyzing various public UDDI registries in order to get various kinds of statistics of web services. Those statistics will be used by both web services developers and consumers for finding them suitable services for their needs. PWSA guarantees that it can provide enough information to find right web services for both Web Services Consumers and Web Service Developers.

The Synchronized Multimedia Integration Language (SMIL) is a declarative markup language based on the eXtensible Markup Language (XML) to define a set of markup tags for synchronizing the timing and positioning relationships between multimedia objects. SMIL makes authoring of TV-like multimedia presentations on the Web easier for applications such as electronic commerce. We present the design and implementation of a JAVA-based SMIL player, which processes different types of media objects using multiple threads. Moreover, its cache engine detects the media type and allocates the proper cache memory for the corresponding media object.

In order to succeed in today's changing business environment, the enterprise should adapt their process flexible. To increase their business process flexibility they need to establish and end-to-end integration internally as well as among partners. Now that SOA (Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In this paper, SOA is introduced And the Web services and ESB (Enterprise Service Bus) are also introduced as a foundation technology to implement SOA-enabled solutions. The pilot project, which introduced in this paper, will be a good reference for future SOA study.

The development of systems that can generate automatically instructional material is a challenging goal for the e-learning community. These systems pave the way towards large scale e-learning deployment as they produce instruction on-demand for users requesting to learn about any topic, anywhere and anytime. However, realizing such systems is possible with the availability of vast repositories of web information in different formats that can be searched, reused and integrated into information-rich environments for interactive learning. This paradigm of learning relieves instructors from the tedious authoring task, making them focusing more on the design and quality of instruction. This paper presents a mobile learning system (Mole) that supports the generation of instructional material in M-Learning (Mobile Learning) contexts, by reusing and integrating heterogeneous hypermedia web resources. Mole uses open hypermedia repositories to build a Learning Web and to generate learning objects including various hypermedia resources that are adapted to the user context. Learning is delivered through a nice graphical user interface allowing the user to navigate conveniently while building their own learning path. A test case scenario illustrating Mole is presented along with a system evaluation which shows that in 90% of the cases Mole was able to generate learning objects that are related to the user query.

전국의 167개 시,도에 있는 교육과학연구원에서는 지역의 교사들이 개발한 각종 멀티미디어 교육 자료를 웹 서비스를 통해 전국의 교사들에게 제공하고 있다. 또한 한국교육학술정보원과 한국교육과정평가원에서도 교육 자료를 개발하고, 더불어 전국의 교육과학연구원에서 제공하는 교육 자료를 통합하려는 계획을 세우고 있다. 그 첫 출발점이 바로 2001년 개발된 한국교육학술정보원의 국가표준 교육정보 메타데이터 형식과 전국의 교육청이 작성하고 있는 교육자료 메타데이터이다. 이 메타데이터를 통해 전국의 교육 자료가 통합되어 서비스될 수 있을 것이다. 하지만 각 시도별로 작성된 메타데이터를 어떻게 통합하고 관리하느냐의 문제는 전국의 교육 자료를 통합하여 서비스하는데 있어, 먼저 해결해야 될 중요한 문제이다. 따라서 본 연구는 분산되어 있는 각 시도의 교육정보 메타데이터를 통합하여 서비스하는 방법으로 XML 웹 서비스 방법과 JDBC를 도입한 3 단계 (-ter) 시스템을 제안해 보았다. 제안된 두 방법을 MS SQL Server 2000과 Oracle 9i에 각각 적용하여 성능평가 한 결과 두 방법이 서로 비슷한 응답시간을 보였다. 따라서 XML 형태의 메타데이터를 검색하는 방법으로 기존의 JDBC를 사용하는 것 이외에 웹 서비스를 이용하는 방법도 고려해 볼 수 있다는 결론을 얻었다.

The use of the Web-based Simulation Environment (WBSE) provides a strong influence on supply chain simulations. A virtual supply chain simulation is available to evaluate strategies for reducing response time to customers and for shrinking the finished goods inventory along its supply chain. This paper presents the basic concepts and definitions of Web-Based Global Supply Chain Management (WBGSCM) simulation system. It also discusses the advantages of supply chain simulation modules integration. A Time Synchronization Mechanism (TSM) called Phased Bucket Scheme (PBS) is introduced as an approach of the distributed simulation modules integration.

대부분의 웹 메일 서비스는 SMTP와 POP3을 이용하여 구현된다. 이런 웹 메일 서비스는 기본적인 송수신 기능뿐만 아니라, 여러 가지 부가적인 기능을 사용자들에게 제공한다. 하지만 메일 송수신 데이터는 그것을 관리하는 서버에 저장되기 때문에, 이 서버에 대한 접속 권한이 없는 일반 웹 메일 사용자는 자신의 메일 데이터를 가공할 수가 없다. 본 논문에서는 XML을 이용한 웹 메일 통합 시스템을 구현하였다. 제안된 시스템에서는 기존의 웹 메일 시스템에 저장된 메일 데이터와 사용자 환경을 B%문서로 변환하고 데이터베이스에 삽입한다. in 데이터를 데이터베이스에 저장하기 위해 XML을 이용한 동적인 문서처리 방법을 사용하고 변환된 XML파일을 레코드 단위로 분석한다. 제안된 시스템은 사용자가 자신의 메일 계정을 변경할 경우에, 구축된 데이터베이스를 이용하여 자신의 메일 데이터와 환경 설정을 쉽게 할 수 있도록 한다. 변환된 XML 문서는 무선인터넷 마크업 언어인 WML(Wireless Markup Language)로도 쉽게 변환 가능하여 모바일(Mobile)서비스를 지원하는 경우, 재구축으로 인한 시간과 경비의 낭비와 개발자의 수고를 덜 수 있다

Purpose - The purpose of this thesis is to assess the product design digital learning status of universities that are currently involved in learning environment projects in manufacture and commerce integration (MCI). Thus, enterprises must keep learning and creating new inventions with revolutionary progress. Research design, data, and methodology - This study not only emphasizes the analysis of technical ability, course concepts, conducting models, and learning environments of every aspect, but also systematically probes the planning of learning, system framework, web learning, environmental activities, data statistics, and digitalized learning, among other aspects. Results - The results of this study help in finally understanding each school's manufacture and commerce integration situation, in order to evaluate product design learning. Consequently, it is essential to evaluate computer learning at schools, thereby affecting communication and the requirements of business education training. Conclusions - It is essential to focus on MCI to promote web teaching to preserve and enhance knowledge disseminating technologies, and immediately share knowledge with learners, while improving work efficiency and cultivating the talent needed by industry.
