This paper describes an Adaptive Context-aware Service (ACS) using Model Driven Architecture (MDA)-based Service Creation Environment (SCE) on PARLAY X based service delivery platform in ubiquitous computing environments. It can be expected that both the context-awareness and adaptation in ubiquitous computing environments will be deployed. But the existing context-aware middleware lacks in considering adaptation. Therefore, the object of this paper is to support the architecture and the Application Programming Interface (API) of the network service for both the context-awareness and adaptation in ubiquitous computing environment. ACS is to provide users with the adaptive network service to the changing context constraints as well as detecting the changing context. For instance, ACS can provide users with QoS in network according to the detected context, after detecting the context such as location and speed. The architecture of ACS is comprised of a Service Creation Environment (SCE), Adaptive Context Broker and PARLAY gateway. SCE is to use Context-based Constraint Language (CCL) for an expression of context-awareness and adaptation. Adaptive Context Broker is to make a role of the broker between SCE and PARLAY G/W. PARLAY G/W is to support API for PARLAY X-based service delivery platform.

Ubiquitous computing will bring on comprehensive changes of environment. We need to understand how this change will change human life and what will be needed in this circumstances. Then we have to develope the appropriate sonics in ubiquitous computing environment. The design of ubiquitous computing environment has the concept of designing human life. Thus to develope the scenarios which are able to predict human life is to make a foundation of developing design concepts effectively. However there is a gap due to the lack of the dear methodology between the analyzing trend of technology and the process of estimating the future life and developing the service scenarios. So, most of the scenarios which have developed up to now do not present the service that exactly reflects all the complicated and pluralistic sides of environment. The service in the ubiquitous computing environment should take the form of grasping the user's context and offering the information with the most adequate way. Therefore we have to know when they need services, where they use services and what kind of services they want. It means that we should understand the life and the environment of user clearly and wholly with the prospect of developing service. We also need the method for developing UC(ubiquitous computing) service based on this. This study focuses on the future family life and analyzes the user's context from a point of view of service development and in this ground, we have progressed the research about the methodology to develop the UC service scenario for suggesting the service. Through the applying of this methodology, we could analyze the user's context systematically and could make the best use of the analyzed data for proposal service idea. And the UC service scenarios which reflect future life on the basis of various use's context could be developed.

USN(Ubiquitous Sensor Network) is the network that widely applies for life of human being. It works out to sense, storage, process, deliver every kind of appliances and environmental information from the stucktags and sensors. And it is possible to utilize to measure and monitor about the place of environmental pollution which is difficult for human to install. It's studied constantly since it be able to compose easily more subminiature, low-power, low-cost than previous one. And also it spotlights an important field of study, graft the green IT and IT of which the environment and IT unite stragically onto the Network. This study realize a IAQM(Indoor Air Quility Management) sensing mechanism composition under the network and suggest the application of Environment monitoring system outlook to measure an Environment element.
