IPTV functions not only as media player that does play the broadcasting industry's contents, also as the gateway is guaranteed of QoS(Quality of Service). This is for free contents-sharing that device stores contents using home network circumstance, and is for watching with seamless network service. Also this have required next QoS model that can handle stably as it may contain more data of the small computing device in next generation home system. We need ubiquitous-oriented QoS's design and development project that focuses on internal and external media service, not the existing QoS nor one-sided QoS of media sevice industry. This paper focuses on network module development. This supports IPTV in media industry and two-way capability of QoS highlighting multimedia service in network industry. In additional, this can handle stably the multiplex signal of USN/RFID as the representative ubiquitous and home network that services high-speed wire and wireless interface, and support the seamless u-QoS.

본 연구에서는 u-City 건설에 따른 도시 기반시설물의 관리 중 특히 교통시설물의 관리를 위한 센서 기반 서비스 모델을 구축하기 위하여 관련 현황을 분석하고 이에 대한 발전 방향을 제시하고자 한다. 이를 위해 국 내외의 ITS(Intelligent Transport System)의 추진현황을 살펴보고, 이를 통해 제공되는 교통시설물 관련 서비스를 교통흐름관리, 교통정보제공, 도로 구조 형성 3개 부문으로 나누어 분석하였다. 또한 USN 기술의 발전 동향을 살펴보아 미래의 u-City 건설 지역에 교통시설의 이용효율을 극대화하고, 교통 이용편의와 교통안전을 제고하기 위한 센서기반의 교통시설물 관련 서비스 방안을 제시하고자 한다.

Up to now, a lot of houses, roads and other urban facilities have been damaged by natural disasters such as flash floods and landslides. It is reported that the size and frequency of disasters are growing greatly due to global warming. In order to mitigate such disaster, flood forecasting and alerting systems have been developed for the Han river, Geum river, Nak-dong river and Young-san river. These systems, however, do not help small municipal departments cope with the threat of flood. In this study, a real-time urban flood forecasting service (U-FFS) is developed for ubiquitous computing city which includes small river basins. A test bed is deployed at Tan-cheon in Gyeonggido to verify U-FFS. Wireless sensors such as rainfall gauge and water lever gauge are installed to develop hydrologic forecasting model and CCTV camera systems are also incorporated to capture high definition images of river basins. U-FFS is based on the ANFIS (Adaptive Neuro-Fuzzy Inference System) that is data-driven model and is characterized by its accuracy and adaptability. It is found that U-FFS can forecast the water level of outlet of river basin and provide real-time data through internet during heavy rain. It is revealed that U-FFS can predict the water level of 30 minutes and 1 hour later very accurately. Unlike other hydrologic forecasting model, this newly developed U-FFS has advantages such as its applicability and feasibility. Furthermore, it is expected that U-FFS presented in this study can be applied to ubiquitous computing city (U-City) and/or other cities which have suffered from flood damage for a long time.

U-Healthcare 서비스는 차세대 의료 패러다임으로 많은 이용자에게 편의성을 보장하기 때문에 사회에서 그 중요성이 인식되고 상용화 시도가 이루어지고 있다. 이러한 U-Healthcae 서비스 시장이 안전하게 형성되기 위해서는 정부의 보안정책이 확실하게 정립되어야 한다. 본 고에서는 안전한 U-Healthcare 서비스의 보안위협을 보안의 3대 요소인 기밀성, 무결성, 가용성을 기준으로 분류하고 살펴본 후 이에 대한 보안정책 방향을 제시하고자 한다.

As the rapid development of IT and the internet changed the trading method from the traditional offline transaction into the online e-Trading, the international documentation standards, the eUCP and the domestic laws and legislations have been established, adapting to the new e-Trading environment. This study was conducted to analyze the factors which affect the use of uTradeHub on the domestic trading companies and trade-related organizations and suggest how to activate e-Trading. To do this, classify the users into the enterprises and the trade-related organizations, set up the hypothesis of the study with the measurement variables of the user convenience, the new service, the system suitability and the legislation environment and carry out a survey targeting the trading companies and the trade-related offices to do an actual proof analysis. The analysis was performed by using the statistical program, SPSS IBM22.0, and the study hypothesis was tested by the multiple regression analysis methodology. The test result showed that the trading companies set a high value on the user convenience, the new service and the legislation environment of uTradeHub, meanwhile the trade-related organizations regarded the system security and reliability, the user convenience and the legislation environment as the major affecting factor on the use of uTradeHub.

With the introduction of the ubiquitous technology, the housing culture centers have demonstrated future housing image or technology. But Ubiquitous Home Services in the future housing were more focused on implementation of environment for the future than exhibition that consumers can experience. The purpose of this study was to identify ubiquitous home services which were realized in domestic future housing and to compare those with results of previous researches on demand for u-services. For this study, field study was conducted with 3 domestic future housings and 14 previous studies on demand of u-services were analyzed by the standard of residents demand. The results of the study showed that u-services for housework and leisure life more than those for security and health, were applied in the future housing. However, residents prefered u-services for security and control of indoor environment to those for housework and leisure life. As a result, it was found thatu-services which residents needed mainly were discordant with those that were displayed frequently in future housing. Also developing u-services reflected the needs of residents, a test bed has to be established in the future housing and then pre-evaluaiton can be conducted.
