With development of computer network technique it joins in recently and ubiquitous computing comes true the research for is actively advanced. The creation rule of registration and search of the event is necessary because the USN sensor data must be possible to specific the multi condition of event which relates on using time. And for using a numerous sensor data provision service, service provider can publish its service in standardized registry for users to search and use the service registry. Currently there is the web service for a WS-Eventing and a UDDI with standard, but the event and the service registry is unnecessary or there is a portion which is insufficient. In this paper, we studied standardization of event definition for USN application service and service registry structure, standard API.

This paper aims at the design of collaborative architecture for business to business (B2B) applications based on Web service protocol. As different business processes should be interfaced in the B2B environment collaboration is important fur the success of B2B implementation. For the development tools, XML, Web services and ASP.NET were adopted Web services are emerging to provide a systematic and extensible framework for application-to-application interaction. The Web services framework is divided into three areas; communication protocols, service descriptions and Web discovery. Web services such as SOAP, WSDL and UDDI correspond to the three areas respectively. ASP.NET is utilized which corresponds to the component and service set located in the top layer of .NET. For the service of product category and product details, Web service architecture was implemented based upon the SQL server database.

With the high interest and the results of active research in life science and Bioinformatics recent years, various information and resources have been produced and new algorithms have been developed to analyze those. Web Services is a computer technology using XML, SOAP, WSDL and UDDI. This paper introduces the One Stop Web Services program developed in CCBB which has a graphic user interface for users.

Resently as ubiquitous environment rapidly emerges due to the development of network and information communication technology, ubiquitous computing is being noticed as a technology that will take the lead in information technology industry of the future. For the realization of this Ubiquitous Service requires some technique such as situations of environment and recognition of locations by the Sensor Network, then sensor data have to be transferred to an application service after processes. Also the creation rule of registration and search of the event is necessary because the USN sensor data must be possible to specific the multi condition of event which relates on using time. And for using a numerous sensor data provision service, service provider can publish its service in standardized registry for users to search and use the service registry. Currently there is the web service for a WS-Eventing and a UDDI with standard, but the event and the service registry is unnecessary or there is a portion which is insufficient. In this paper, I design and implementated standardzation of event definition for USN application service and service registry structure, standard API.

In an proposed Context-Aware SOA(Service Oriented Architecture) based OSGi(Open Service Gateway initiative) platform, Service provider manages relative kinds of services in an integrative basis from various sensors, puts each service in a SOAP (Simple Object access Protocol) message, and register thorn to the UDDI(Universal Description Discovery and Integration) server of service registry, service requester retrivel the specified kinds of services and call them to service provider. Recently most context-aware technologies for ubiquitous home network are mainly putting emphasis on RFID/USN and location-based technology. Because of this, service-oriented architecture researches have not been made enough. Under the environment of an OSGi service platform, various context-aware services are dynamically mapping from various sensors, new services are being offered for the asking of users, and existing services are changing. Accordingly, the data sharing between services provided, management of service life cycle, and the facilitation of service distribution are needed. Taking into considering all these factors, this study has suggested an Context-Aware SOA based eclipse SOA Tools Platform using OSGi platform that can transaction throughtput of more than 546 TPS of distributional Little's Law from ATAM(Architecture Tradeoff Analysis Method) while remaining stable other condition.

The world is rapidly evolving in the future society is based on intelligence. In such circumstances, USN(Ubiquitous Sensor Network) to implement the future ubiquitous(Ubiquitous) society have been highlighted as a key infrastructure. For realization of Ubiquitous computing(Ubiquitous Computing), The data recognized from each sensors must be collected on real-time and transferred to applied service so that they may be used as data for providing service to users. USN sensor data on the use for using a numerous sensor data provision service, service provider can publish its service in standardized registry for users to search and use the service registry. However, in previous studies using Web services standards WS-Eventing, and UDDI(Universal Description, Discovery, and Integration) as USR(USN Service Registry) for USN Application Service is unnecessary or insufficient. In this paper, data from sensors that provide information to service providers register their services and use the information for service users to explore and views on the registry of the system was designed and implemented.

For global electronic market, several market place standards are developing now. Though, a standard is different from others they are pursuing the same purpose of uniworld market. In this study, two standards(ebXML and UDDI) which are most strong enough to urge field engineers to consider the standards in making their products were focused. Additionally, the development priorities of ebXML which were viewed from field engineers were summarized. Finally, government actions required by field engineers to promote the development of global market place were summarized.

웹 서비스는 SOAP, WSDL, UDDI와 같은 표준을 기반으로 인터넷상의 분산된 여러 서비스들을 통합하는 가장 효과적인 방법으로 알려져 있다. 이러한 통합을 위하여 웹 서비스 표준 프로세스 통합모델 언어인 BPEL4WS가 제시되었다. 이와 같은 분산된 서비스 통합 시에 서비스 신뢰성 확보를 위해서는 통합 환경 상의 품질 관리가 필요하나 확실한 대안 책이 없었다. 이에 본 논문에서는 사용자와 공급자 사이의 협정을 통해 품질 보증하는 SLA를 이용하여, BPEL4WS로 통합한 환경에 적합한 품질 보증기법을 제시한다. 또한 제시한 기법의 효율적인 활용을 위한 웹 서비스 통합 프레임워크를 제시한다.

오늘날, 웹서비스를 이용한 정보 검색을 하기 위해서는 UDDI 레지스트리의 전문적인 지식이 필요하다. 즉 웹 서비스를 명세하기 위해 사용된 카테고리와 이에 대한 값, 이름 등을 사전에 알고 있어야 한다. 그러나 일반 사용자들은 이러한 사전지식을 충분히 알고 있지 못하면 웹서비스에 대한 정보 검색을 쉽게 할 수 없다. 그러므로 일반 사용자들을 위해 웹서비스에 대한 점보를 카테고리에 맞게 분류하여 검색을 용이하게 할 수가 있다. 따라서 본 논문에서는 보다 효율적으로 웹서비스 정보를 분류하기 위해서 유전자 알고리즘과 신경망을 이용한 클러스터링 기법을 제안하는데 목적이 있다.

최근 인터넷의 급속한 발전과 사용자의 욕구증대에 따라 웹 어플리케이션 형태로 서비스를 제공하려던 것이 이제는 다양하게 산재해 있는 개별적인 웹 어플리케이션들을 효율적으로 통합하는 웹 서비스 방식으로 진화하였다. 웹 서비스는 XML 기반 표준인 XML, UDDI, WSDL, SOAP등을 이용하여 플랫폼이나 지리적 위치에 관계없이 분산된 애플리케이션들이 서로 통신할 수 있도록 한다. 웹 사이트가 점차 많아지고 컨텐츠의 양이 방대해짐에 따라 나타난 웹 컨텐츠 관리 시스템은 웹 서비스와 같은 XML 기반의 시스템이다. 웹 서비스와 웹 컨텐츠 관리 시스템을 결합할 경우 인터넷은 거대한 분산 데이터베이스가 될 수 있다. 이에 본 논문에서는 웹 서비스를 기반으로 한 웹 컨텐츠 관리 시스템을 제안한다.
