U-city is one of the most competitive field in Korea in the future and it has many subdivision applying field. U-health and u-disaster are important fields of u-city and many projects are being done about those fields. Because each filed is being developed independently, the better efficiency cannot be expected in case of disaster. The most important focus in disaster is the maintenance of human life and dignity, so u-health and u-disaster should be developed together and organized as the same filed for the practical assistance in case of disaster.

Starting from 2005, as the new city paradigm, the term 'u-City' was created in Korea. U-City service, as defined in "u-City law", is a service that connects and intermediates among government, traffic, welfare, environment, disaster mitigation, etc., and their data based on ubiquitous city technology and infrastructure. According to the survey executed by local governments, the improvements in the standard of living of citizens have in turn increased the needs for anti-mitigation services. Such trend is bolstered with the recent disasters such as the conflagration of Korean Soong-rae Gate and the devastating earthquake of Sichuan province. This article describes a concept of the u-City disaster prevention service and looks into the activities and planning of u-City disaster prevention service of local governments. This paper also briefly looks into the law and policies to derive the needs of u-City disaster prevention service as well as the current technologies and u-City disaster prevention services of local governments. Ultimately, this paper offers the strategic direction of developing u-Disaster Prevention City.

본 연구에서는 수직 밀폐형 지중 열교환기를 현장 시험시공하고 현장 열응답 시험을 수행하여 보어홀과 지반의 유효열전도도를 측정하였다. 뒤채움용 그라우트재는 벤토나이트와 시멘트가 고려되었으며 첨가제로는 천연규사와 흑연을 사용하고, 지중 열교환기 파이프 단면은 일반적으로 시공되는 U-loop 파이프 단면과 파이프 사이의 열간섭 효과를 최소화 한 3공형 파이프 단면이 착용되었다. 시멘트-천연규사 그라우트재가 벤토나이트-천연규사 그라우트재 보다 큰 유효열전도도를 보이고 흑연을 첨가한 그라우트는 시멘트와 벤토나이트 모두에서 천연규사만 첨가하였을 때 보다 유효열전도도가 높게 나타났다. 3공형 파이프 단면의 경우 단면에 따른 영향을 비교하기 위해 그라우트는 시멘트-천연규사와 벤토나이트-천연규사를 사용하였으며 유효 열전도도 측정결과 각각 3.65 W/mK, 3.40 W/mK으로 일반 U-loop 파이프 단면을 사용하였을 때 보다 높게 나타났다.

본 연구에서는 동해고속도로 설계시 나타난 연속터널을 대상으로 하여 터널내 오염농도 해석 및 터널내 오염농도의 거동 및 터널 갱구부 주변의 오염물질의 재유입 여부를 분석하여, 연속터널에 대한 터널내 외부유동에 대한 환기영향을 검증하였다. 또한 연속터널 연결부에서의 캐노피 설치방안, 결빙대책 및 조도순응대책 등을 검토하여 연속터널에서의 환기 및 방재특성을 고려한 합리적인 고속도로설계가 되고자 하였다.

The typhoon is provoking huge damage attacking in Korea periodically every year. Therefore, in this study, the analysis of 24 hourly maximum precipitation change related to typhoon events achieved based on Mann-Whitney U test, T test, Modified T test, Sign test, F test, and Modified F test. At the results, the 24 hourly maximum precipitation was expose that average and standard deviation are increasing recently. Therefore, hydorlogical structures have to be prepared of extreme rainfall events by typhoons.
