U-City law was enacted U-City construction to support efficiently. But U-City planning system is not set. And detailed instructions are not also available. In particular, U-City data is not available and specific plans and instructions. Therefore, in this research, "U-City Law" by the state and local governments need to establish in the U-City Comprehensive Plan and the U-City master plan to be included in U-City data management was presented matters. U-City comprehensive plan provides the direction of the U-City master plan. Detailed action task are (1) U-City data management standards for the establishment of cooperation and sharing (2) Establishment of U-City data processing and activation (3) U-City data distribution system infrastructure (4) Establishment of data quality and price. U-City master plan is based on the U-City comprehensive plan. And U-City master plan for the data managements are (1) U-City data on the production plan (2) U-City data on the collection plan (3) U-City data on the processing plan (4) U-City data on the activation plan (5) U-City data on the distribution plan.

This paper investigates the spillover effects(co-movements) between korean and U.S stock market by KOSPI and DJIA Index. Especially it compare to the pre- and post period of U.S. financial crisis resulted from sub-prime mortgage loan. The main results are as follows. First, the spillover effects of DJIA(U.S. market) to KOSPI(Korean market) are strong. This result accord with the former researches on this subject. Second, spillover effects are more strong after U.S. financial crisis. A possible reason for this phenomenon is a trend which the major investors such as foreign and institutional investors in domestic stock market have more attention to U.S. stock market. Third, the spillover effects appear in the opposite direction, that is KOSPI(Korean Stock Market) to DJIA(U.S. Stock Market). It seems to be the results of asian stock market's growing infIuences to European and U.S Markets.

In the proposed u-health service platform mobile u-health served an a series of process of bio data collection and storage and bio data analyses and results notice, and I interpreted it to a process. I became a design so as the service platform which supported health management system construction easily loaded service applied mobile u-health, and to be able to operate it in mobile environments, and took utility of a service platform and usability into consideration, and I got the crux of u-health use service.

In this paper, we propose a secure and efficient RFID-based patient authentication protocol to not only authenticate patients' authenticity but also protect patients' personal medical informations for u-Healthcare environments. Since the proposed RFID-based patient authentication protocol provides strong security and efficiency, it can be used practically for patient authentication and personal medical information protection on the high technology medical environments such as u-Hospital and u-Healthcare.

본 논문에서는 유비쿼터스 환경에서 발생되는 웹 서비스들의 컨텍스트와 웹 서비스간의 연관 관계를 워크플로우(workflow) 형태로 기술하기 위한 XML 기반 언어인 uWDL (Ubiquitous Workflow Definition Language)을 소개한다. uWDL은 유비쿼터스 환경에서 이종(heterogeneous)형태로 존재하는 서비스 요소(element)들을 워크프로우 방식으로 표현할 수 있다. 또한, uWDL은 유비쿼터스 환경의 웹 서비스를 수행하는 워크플로우 시나리오가 uWDL 문법에 맞게 작성될 수 있도록 uWDL용 DTD를 설계하였고, uWDL 문서의 유효성(validation) 검사를 위한 uWDL 파서를 설계하였다. 유비쿼터스 환경에서 발생하는 웹 서비스 개발을 위해, 개발자는 uWDL을 이용하여 유비쿼터스 환경의 사용자 특성을 고려해 그에 맞는 서비스들의 관계를 워크플로우 형태로 쉽게 기술할 수 있고, 응용 프로그램이 요구하는 웹 서비스들 간의 연관 관계를 컨텍스트 기반으로 정확히 기술함으로써 작업을 통합하고 자동화를 이룰 수 있다.
