분산된 서비스의 통합의 중요성이 커지고 있는 최근의 유비쿼터스 환경에서 SOA(Service Oriented Architecture)의 구현기술인 웹 서비스는 이러한 분산된 서비스를 연계하는 표준기술로서 기업내, 외부뿐만 아니라 방송/통신 융합, 정보가전/홈네트워크, 임베디드 환경 등 다양한 분야에서 사용되어 지고 있다. 본 논문에서는 홈네트워크에서 사용되는 디바이스등을 상호 이질적인 플랫폼이나 프로토콜에 유연하게 제공하기 위한 서비스 변환 게이트웨이 역할을 하는 SCG 엔진(Service Convergence Gateway Engine)과 서비스 연계의 표준기술로 자리잡고 있는 웹 서비스를 기반으로 SOA를 지원하고 S/W Service와 Application Component간의 연동을 위한 경량화된 Backbone의 역할을 수행하는 ESB(Enterprise Service Bus)를 사용하여 서비스를 통합하고 관리하는 구조를 제안 한다.

To survive in rapidly changing business environment, the enterprise should adapt its business process to the changing environment. The system integration is an important issue to tackle this challenge. It is unavoidable direction 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) ate also introduced as a foundation technology to implement SOA-enabled solutions. The pilot project, which is introduced in this paper, will be a good reference for future SOA implementation.

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.

In recent years, ubiquitous and pervasive scenarios have emerged as a complex ecosystem where differentiated software/hardware components interoperate wirelessly and seamlessly. The goal is to enable users to continuously access services and contents, and to always get the best out of their current environment and available resources. In such dynamic and flexible scenarios, the need emerges for flexible and general solutions for continuous runtime self-reconfiguration and self-optimization of ubiquitous support software systems. This paper proposes a fully reconfigurable middleware approach that aims at reconfiguring complex software systems made up of heterogeneous off-the-shelf components from both functional and non-functional perspectives. Our middleware can also extend already existing and non-reconfigurable middleware/applications in an easy and flexible way, with no need to re-design them. The proposed design principles have been practically applied to the implementation of a runtime self-reconfigurable middleware called Off-The-Shelf Ready To Go (OTS-RTG), implemented on top of iPOJO. The reported experimental results both exhibit a limited overhead and show the wide applicability of the proposed solution to many application scenarios, including complex, industrial, Enterprise Service Bus-based ones.

To survive in rapidly changing business environment, the enterprises of all over the world are trying to integrate their IT infra structure and are trying to automate their business process. Service Oriented Architecture (SOA) is being accepted as an IT standard to support efficient system integration and flexible business process automation between enterprises or departments. The material control system is required this software architecture between manufacturing company and materials supply vendors. This paper introduces concept of SOA, relevant technology about SOA such as Web Services and Business Process Execution Language (BPEL) and Enterprise Service Bus (ESB) and describes how to automate materials control process by designing the material control system based on SOA. The analysis of requirements is proceeded by Unified Modeling Language (UML) and SOA delivery strategy is selected the top-down strategy. And this paper describes how to derive services and operations and how to arrange services in three service layers and how to design business process.

Today, our country is experiencing serious graying without parallel. The government is executing various services and welfare policies to solve this problem using ubiquitous technology. But the old and disabled people are not good for using the u-service and system, because it is made for ordinary people. The purpose of this study is to solve the graying society-problem and improve the eldery as well as disabled's quality of life by integrating each information centers based on ESB(Enterprise Service Bus). The results of this study can be divided by system architecture and communication system for the eldery and disabled. The research development results of this study can be used to build the integrated information center for u-service of the old people and disabled. It will contribute to realizing the Ubiquitous-society by promotion of young people's quality of life as well as the eldery and disabled.
