A paradigm of medical industry is changing quickly to u-healthcare according to entry toward an aging society and improvement of quality of life(QoL). The change toward u-healthcare is meaningful since meaning of healthcare is redefined by prevention and management instead of medical service such as diagnosis of disease and treatment. However, the interest about u-healthcare is only concentrated to derivation of new healthcare service, development of medical measurement appliances(Sensors), and integration and standardization of medical information. Therefore, in this paper, the main ai of this study is trying to realize and implement u-healthcare technology through primary philosophies of ubiquitous composition such as Disappear Computing, Invisible Computing, and Calm Computing and development of user-centered technology.

As a way to serve housing information providing on internet will be a useful method in the near future in Korea. This study was planned to review the housing information on internet network which provided by U. S. .University CES(cooperative extension service) Comparative analysis was used as a Research method in terms of contents and items about housing information on internet provided by U. S. university CES during two weeks each in August 1997 and July 1998. Findings are as follows; Universities providing housing information and information items had been remarkably increased during one year since August 1997. Most of housing informations except one university CES were free to use in 1997 but three university CES among 12 universities showed only the title of items with charge amounts in 1998. Informations about 'Housing Management' and 'Environment' items were the large parts of the housing information in 1997. In 1998. 'Environment' items were remarkably increased. Items bout insects and mildew removing were large portion of the 'Housing Management'. Items about energy saving water and air quality were large portion of the 'Environment' These findings will be useful to develop items of housing information on internet network with Korean language which should be compensated by the survey research.

As being various user telephone number after entry of new telecommunication enterprise, management of systematic Directory Assistance Service is required. Also through providing competition of Directory Assistances Service, enhancement of Service quality and development of new Service are induced. In this study, there is researched the overall view of present Directory Assistance Service in priority Korean Telecom and the oversea's Directory Assistance Service for U.S.A, England, Australia, Japan. As result of study, we want to suggest the appointment of unified Directory Database Management Company and outsourcing of Directory Assistance Service to that company but in reality, there may be other idea also with regard to various circumstances.

In this paper, we introduce an integrated performance evaluation model defined by the three indices (evaluation index for each evaluation stage, performance viewpoint, and performance type) and analyze the utilization and satisfaction of the seven public u-IT services implemented from 2008 to 2009 using the proposed model. From the performance results of the public u-IT services, it was found out that most of the research goals initially set by the public u-IT service support projects were satisfied. Furthermore, we suggest improvement directions and promotion strategies of future projects.

For the development and management of u-City(ubiquitous city), Ubiquitous City Construction Law was enacted(March 3, 2008) to form the legal basis of u-City plan, construction and managements afterwards. Among u-City elements, the u-City Management Center has its own meaning and importance in roles which are crucial to the u-City developments, and its legal establishment is one of the core u-City realization factors. The purpose of this study is to analyse its overall problem issues regarding the function and location of u-City Management Center and then to suggest the basic direction and enforcement strategies to form its legal basis. As a result, in order to enhance the possibility of successful realization of u-City Management Center, the classification and standardization of function type, allocation of detailed functions based on u-City project hierarchy, and practical definition and relationships among basic u-City components such as u-City Service and Infrastructure were suggested. Also, practical execution devices on revenue sources and private sector participation, as well as the legal basis stipulating the mandatory inclusion of u-City Management Center development for u-City projects, were suggested.

Many researches and projects are implemented about u-IT according to changes of ubiquitous environments in the world. Especially, there are benefits to raise lifestyle and we can develop industry by applying ubiquitous regionally. Also it makes citizen feel comfortable directly. There are many projects to regionally adopt ubiquitous services like u-City model for getting this advantages. RFID technology must be suited to each environment because each RFID tag has different characteristics according to frequency band. We need to integrate bands of RFID to overcome limitations and provide more detail information and services. In this study, we develop the dual band RFID Manager needed adopting u-Zone service for both 13.56MHz and 2.45GHz. The RFID Manager, application software for base station of u-Zone, delivers the information from readers to integrated u-Zone server system.

The purpose of this study is to present the role of NGIS(National Geographic Information System) and the development strategy for Business GIS in the ubiquitous society. We analyze the level of GIS technology with the ICT(Information Communication Technology) as well as GIS application trends especially in location-based circumstances. Also, we advocate not only making GIS contents to meet the international standards such as GML(Geography Markup Language) and TPEG(Transport Protocol Experts Group) but applying GIS as a killer application to oncoming diverse ICT areas including LBS(Location -Based Service), Telematics, ITS(Intelligent Transport System), gCRM(geographic Customer Relationship Management), DMB(Digital Multimedia Broadcasting), u(ubiquitous)-City and u-Town. Finally, we build a conceptual Business GIS model based on NGIS for QoS, standardization, R&D, education, and security.

현재까지 USN(Ubiquitous Sensor Network)이라 통칭되어지는 센서망은 불특정 공간에 배포된 무선방식의 센서노드를 통해 유선방식의 센서 인프라를 대체하려는 기술 지향적 및 공급자중심의 구성을 가지고 있다. 본 논문은 기존의 공급자 위주의 기술지향적인 제한적 구성에서 벗어나, u-City에서 제공하고자 하는 서비스들의 목적과 서비스 대상의 요구사항분석을 기반으로 성능, 품질, 비용 등을 고려하도록 다양한 기술들을 융 복합하여 서비스를 제공하는 하이브리드 센서망의 제안을 위한 선행 연구 결과이다. 우선, 센서망과 u-City 서비스와의 관계에 대해 서술한 후, 기존 센서망에 대한 조사, 분석 결과 및 문제점, 그리고 선진국에서의 하이브리드 센서망 적용 사례와 시사점에 대해 논의하도록 한다.

The wide deployment of wireless access technologies and the integration of various access network interfaces into a single terminal, allows mobile end-users to be always connected to the IP network, and to use those interface simultaneously. In this paper the CTE provides various access network interfaces capabilities, allowing reception of data over multiple service providers with different characteristics. Considerations for multiple network and service provider environments are regarded as essential for the successful deployment of convergence services in Next Generation Network (NGN). Event Driven Service (EDS) is regarded as a typical convergence service converging different functions of multiple service providers. This paper first describes the deployment model of NGN convergence services for multiple service provider environments. It also covers the service scenario of EDS, a convergence service for multiple service provider environments in NGN. Multiple provider environments stimulates the unified identifier management, namely ubiquitous identification (U-ID), to enable users to be provided convergence services without awareness of multiple provides. Then the designed structure and procedures of U-ID based EDS are given. Finally, the implementation results tested on Korea Advanced Research Network (KOREN) are described.
