  • This study is about the investigation of the walking environment of the First Experimental Elementary School in Shapingba District of Chongqing City and the Zaozilanya Elementary School in Yuzhong District and the analysis of the pedestrian's consciousness. The improvement plan is obtained by comparing and analyzing the walking environment around the school. The survey results are as follows. According to the survey results of the walking environment around the school, the sidewalks of the two schools are relatively narrow, and there are more pedestrians crossing the road. There is a phenomenon of parking in both schools. The phenomenon of parking in Zaozilanya Elementary School is even more serious. In investigating the most important elements of the school's pedestrian environment, the setting of the signpost, the setting of the crosswalk and signal lights, the setting of the fence, the setting of the vehicle's deceleration facilities, and the control of the school gate are all necessary. Therefore, in order to create a safe and comfortable improvement plan for the surrounding environment of the school, first of all, in the improvement of the facilities around the school, the setting of the fence, the setting of the speed bump, the improvement of the crosswalk and the signal light. Second, in terms of restrictions, the scope of protection around the school needs to be expanded, and restrictions on parking and restrictions on vehicle traffic need to be implemented. Third, in terms of education and publicity, it is not only necessary to provide safety guidance for students to go to school, but also to provide drivers with driving safety education and publicity.

  • 철도용 지장물검지장치는 2004년 고속철도와 함께 도입되어 산사태, 낙석 및 과선교로 부터의 낙하물과 같은 장애물에 의한 사고를 예방하고 있다. 다만 기존의 시스템은 검지선의 단선 여부에 대한 사항밖에 검지가 불가능 하여 산사태나 과선교 위로의 물체 낙하 등에 대한 검지에 제약이 있는 것이 사실이다. 이에 이번 연구에서는 OTDR, 광펜스 및 검지용 카메라로 구성되어 개선된 지장물검지시스템을 제안한다. 이 연구에서 제안하는 시스템은 단선 상태에 대한 검지 이외에도 광펜스에 대한 가압 및 특정지역에 대한 영상 검지가 가능하도록 구성된다. 개발 시스템의 핵심부인 광펜스 및 OTDR에 대한 프로토타입 시작품을 제작하고 기능시험을 실시하였으며, 개선된 검지 능력을 입증하기 위한 결과들을 획득하였다. 추후 연구에서는 현장함 설계 및 환경시험을 실시할 예정이며 이후 현장 시험을 진행할 예정이다.

  • The prevention of disasters in cultural property is very important management and historical duties. The reason can't be measured values with monetary scale of our contemporary. Therefore, this paper was considered fire-safety as one of terrible threat-disasters about the wooden buildings. This research deal with 47 cases cultural property wooden building by whole investigation(field survey and interview) in Gangnung province. The most buildings have basic fire extinguisher; ABC powder. A few buildings are rarely installed fire extinguishing equipments; outdoor fire hydrant, heat sensor, ground sprinkler, CO2-hose-reel. But these state is very insufficient for the fire-safety in cultural property wooden buildings. Specially as particular attention in province, forest fire of regional characteristic have close relation with cultural property fire. The majority of factor against forest and building fire is to provide monitoring and security system; CCTV, Fence, Sensor, Alarm and paid guard man against incendiary. Ultimately it is necessary to construct comprehensive disaster prevention system with the organic cooperation such as National Emergency Management Agency, Cultural Heritage Administration, Forest Service, local government officials and regional citizen.
