While the use of large scale underground complex space is increasing currently, this research suggests the methodology of servicing advanced service for civilian and constructing active disaster protection system in order to be free from danger problem of underground complex space by applying new ubiquitous technology. Synchronization between virtual space and real space and construction of ubiquitous disaster protection system arc the core technology. Based on RFID, USN technology, usually, user centered spatial information services are presented. it can be convert to disaster protection system on emergency situation without delay. Through these technology. we can ensure the safety of underground space where the floating population is concentrated in, moreover, utilize for infrastructure that presents various civilian services. Then we can satisfy the increasing civilians desire for safety and welfare and finally, it will contribute to construction of productive city and creation of new conceptual market.

This Analyzed case study of measuring displacement, implemented laboratory investigation, and in-situ testing in order to interpret ground subsidence risk rating by excavation work. Since geological features of each country are different, it is necessary to objectify or classify quantitatively ground subsidence risk evaluation in accordance with Korean ground character. Induced main factor that could be evaluated and used to predicted ground subsidence risk through literature investigation and analysis study on research trend related to the ground subsidence. Major factors of ground subsidence might be classified by geological features as overburden, boundary surface of ground, soil, rock and water. These factors affect each other differently in accordance with type of ground that's classified soil, rock, or complex. Then rock could be classified including limestone element or not, also in case of the latter it might be classified whether brittle shear zone or not.

하천제방 축조를 위한 많은 양질의 성토재료는 시공헌장에서 쉽게 구하기 어려우며, 하천제방의 경제성 및 안정성에 있어서 가장 중요한 요인이라 할 수 있다. 따라서 경제적이고 안정적인 하천제방을 축조하기 위해서는 하상재료를 이용한 제방축조기술의 연구가 필수적이며 이를 위해서는 하상재료에 대하여 현장시험을 통한 설계 및 시공방법, 공학적 특성 분석이 요구되어진다. 본 연구에서는 대구 현풍천의 하상토(SP)를 대상으로 원재료 및 양질토인 화강풍화토(SW)와의 혼합에 따른 현장 다짐에 따른 공학적 특성을 평가하고 현장 혼합방법을 제시하였다.

The slope stabilization method is constructed on bedrock, but performance degradation occurs during an impact (earthquake, blasting, etc.) after construction, which may affect service life and factor of safety. In particular, the top-down method implies the possibility of damage caused by blasting vibration due to the construction procedure. However, the current blasting design only reflects damage to nearby facilities, so there is a limit in its ability to assess the damage of reinforcement methods caused by blasting vibration within the scope of influence. In this study, we aim to evaluate problems and damage levels caused by close blasting effects on rock-integrated structures, such as panel-type retaining walls, anchor-combined structures, and small nails, which are mainly constructed using the top-down method. We will also analyze factors affecting long-term performance according to changes in conditions after construction, such as tunnel excavation, to establish optimal design measures.

Recently, disaster that is earthquake, sever rainstorm and the tidal wave were increased by abnormal weather. These influence which is the slope stability of the completed slope as well as under construction slope is affected by disaster. But the management standard for the construction slope is incomplete. Also, the standard connected with construction slope is not integrated with the important public paper organic enemy and it is duplicated and the standards which conflict are being scattered. In this research which it sees consequently the inside and outside of the country construction slope the maintenance civil official relation law and standard investigation it leads and the problem point and a improvement program of management criterion and to sleep the construction slope which is suitable in domestic actuality it prepares and propose.

The study seeks to cooperate with the investigation of a fire investigation based on public-private partnership. Fire protection systems provide a wide variety of viewpoints from the perspectives of design, construction, management, maintenance, maintenance and maintenance systems at a particular point in time, construction, management, and maintenance systems. What is controversial is that there are illegal activities such as illegal activities of the Patent Office, misconduct of construction work and unreasonable construction of construction works.As a theoretical framework, the present study identified the four key elements of a successful disaster response system : responsiveness, control, professionalism, and bias.

This study is to investigate the degree of field awareness of how each provision of the Serious Disaster Punishment Act will affect accident prevention. As a result of conducting a survey of construction site workers, it was analyzed that construction site workers had a low sense of safety and did not voluntarily engage in safety activities. And it can be seen that they are taking a very passive position that it is efficient to implement safety under the supervision of the supervisor. Workers who need voluntary construction site safety activities are most aware of the situation at the site, but the problem was pointed out as "lack of procedures for listening to opinions and preparing improvement measures" for these problems. Future research is needed to see if this is a problem for individual workers or for those in charge of safety and health who do not correct it even though active opinions have been submitted.

Smart-Phones are utilized in disaster management field because it can deliver disaster information to large population simultaneously and quickly, and provide accurate information through situation-based service using the LBS(Location Based Service). To study on the utilization of smart phone for disaster information collection and dissemination method, this study suggest a framework which connects smart phone by loading application for reporting disaster. The disaster monitoring and situation dissemination system framework using smart phone is composed of 4 parts. First, smart phone application enters image, video, voice and text information and location of the disaster. Second, the disaster report reception and situation dissemination server receives the information, save in the DB, and send through smart phone SMS. Third, store into disaster information database. Fourth, display the disaster report and management information on 2D GIS, support the decision making process in deciding whether to manage as disaster, and disaster management web service which disseminates situation.

지금까지 재난에 대한 대비는 재해 발생시 대응 및 복구에 초점을 두었지만 예방적 차원의 접근이 점차 중요해지고 있다. 이를 위해서는 재해에 취약한 지역을 사전에 파악하고, 이를 체계적으로 관리하는 것이 필요하다. 본 연구는 대도시관리차원에서 필요한 방재지도의 유형으로 화재를 상정하여 화재위험지역을 선정하는 기준을 설정하고, 이 기준에 맞춰 서울시 종로구 창신동을 사례지역으로 하여 화재위험지도를 시범적으로 구축하였다. 화재위험지도 작성은 방재업무에 있어 지역성에 기초하여 취약지구를 사전에 파악하고 체계적으로 관리하는 데 활용될 수 있으며, 나아가 지구단위계획등의 도시계획업무에서 방재를 고려한 토지이용계획 수립 및 도시계획시설 배치등에 활용될 수 있을 것으로 판단된다.
