In Korea it continues to grow elderly population, especially the elderly who lived alone and above-average temperatures is increased by global worming lately. So that, to take immediate action and to solve social isolation for elderly people living alone, we prospect it plays an important role ubiquitous information technology(IT) such as Geosensor based on GIS, RFID and wireless sensor networks, etc. In this paper, we searched domestic and foreign response status of heat wave for the elderly and proposed u-Care service for the elderly to stay indoors during heatwave warning. In future, we will design u-Care system and carry out various researches on accuracy, revitalization, the law, etc.

Increasing the need of national safety management system in order to an epoch-making improvement to scientific disaster management which appears new types of disasters through the exchange of traditional disaster environment and responds actively to the rapid exchange of social environment based on u-IT. Requiring the development of systematical information sharing networking system and sharing realtime data amongst government, local authorities and related organisations under both safety management in normal times and circumstance management in disaster times, and need for the establishment of national safety strategy, which has been strengthened function such as prevention and preparation. This research provides a basic scheme and strategic tasks in order to constitute preventing scientific national disaster prevention structure at anytime and anywhere from disaster which is based on ubiquitous technology and realise the intelligent national disaster prevention system of u-safe Korea.

U-Channel Bridge is effective bridge type, because its edge beam performs role of barrier and enables to reduce additional dead loads. Nevertheless, there is possibility of bridge collapse under impact load due to car crash. Also, edge beam must have ability to induce safe driving and prevent falling accidents. Therefore, this study carries out analysis of behavior of edge beam and slab and evaluation of structural stability under impact loads, based on Korean Highway Bridge Design Specifications and AASHTO LRFD Bridge Design Specification. According to analysis result, the maximum stress of edge beam and slab satisfies specification of allowable stress.
