Recently our country was entering a high-tech society with social and economic development. However, the individual's ability to respond to disasters is lowered by the increase in complexity society. Accurate situation assessment and disaster response by a margin of personal information that can identify when a disaster has been difficult. Until now, by leveraging Standard speaker was the emergency alert broadcast. However, it was difficult to have regular speakers reverberation, a distinct attenuation of sound by listening to the sound, etc. due to the reflection of sound. By using a directional speaker that is characteristic of the sound attenuation of sound is straight to solve this problem and obtain feedback on measures that can effectively provide the oocytes to a valid information on a disaster situation and the evacuation.

The purpose of this study is to present the possibility of adopting beacons to implement the fire evacuation guidance system in order to reduce the evacuation time for a fire in complex buildings. A beacon-based evacuation system can quickly detect a fire's origin, optimal path of evacuation involved with the exits and the location of evacuees using information collected by the proposed system. The assessment is conducted by integrating different scenario models including fire simulation. Based on the research result, beacon is an effective tool to warn potential hazards or to provide early detection and a safe escape.

안전한 생화환경에 대한 국민수요 급증 및 사회변화에 따른 장기적 관점의 재난관리체계가 필요하고 우리나라의 경제성장이 거듭됨에 따라 고도화된 기술문명 사회로 급속히 발전한 결과 과거와는 달리 지하철 사고, 가스폭발사고, 화학물질 분출사고 등 사회재난의 유형이 다양화되고 있을 뿐만 아니라 그 피해의 양상이 복잡화 되고 있어 이에 대한 전략적인 대응이 필요하다. 따라서 본 연구에서는 사회재난 사고유형 및 대응사례 분석을 통한 재난대응 시나리오를 개발하고, 관련 법제도 검토를 통해 법개정 방안을 수립하여 시범사업 기반 구축의 방향을 제시하고자 한다.

사물 인터넷을 기반으로 지하철역사의 재난 전조를 조기에 발견하고 승객들에게 피난을 유도하는 지하철 재난전조 감지 시스템 개발에 있어서 재난 발생시 상황대피 유도방법과 정확한 재난 위치 알림 및 대피경로 안내는 재난 상황에 빠른 대피와 인명피해를 최소화 할수 있는 매우 적극적인 대안이 될 수 있다. 따라서 본 연구에서는 대피를 가장 효율적으로 유도할 수 있는 재난대응 EL Display 통합 보드를 개발하였으며 이를 현장 실험을 통해 실제 활용성에 대한 검토를 실험하였다. 특히, EL패널을 재난 대피유도용으로 활용한 사례가 없어 현장적용테스트를 거쳐 그 활용 가능성을 검증하였다.

The 14 cities and guns within Gangwon-do were divided into three regions (urban-rural-integrated type, urban type, and ruralcoastal type), and local voluntary disaster prevention organizations in those regions were surveyed as sample groups. As a result, the urban-rural-integrated type and the urban type were found to be lower than the rural-coastal type in all domains including recognition of disaster crisis, evacuation guidance, preparation of voluntary evacuation, maintenance of disaster prevention system, surveillance & guard, and information delivery. In particular, three types had higher information delivery but considerably lower preparation of voluntary evacuation. As for information delivery, foundations for rapid delivery of disaster information due to establishment and extension of systems for forecasting and warning of local governments were prepared, but as for preparation of voluntary evacuation, it is needed not only to perform consistent training and promotion for preparation for disasters for residents to accurately understand status of disasters but to take measures to secure safe places for evacuation beforehand.

This study aims at proposing a method to guide people to the most efficient route in an emergency through addressing the limitations of the existing research and providing a solution. Most of the existing intelligent guidance system tend to guide people to the shortest-distance path to the exit. A problem lies to the fact that the shortest-distance path doest not gurantee the most efficient way of evacuation. Rather than taking the shortest-distance path, this research proposes a way of taking the shortest-time path by introducing a real time loop sensor.

The purpose of this study is to prevent fire accidents in advance by deriving prior knowledge among groups about temporary fire-fighting facilities of workers at construction sites and devising appropriate improvement measures. The findings are as follows.First, in the case of fire extinguishers, statistical attention was paid to the contractor, supervisor, partner worker and fire extinguisher manager between designations. 87% of fire managers and 70% of facility supervisors said fire extinguisher management managers needed to be designated for each type of construction, which requires designation of fire extinguisher management managers, frequently checking and relocating. Second, in the case of simple fire extinguishing facilities, statistical attention was paid to the application of penalties for unauthorized use of fire extinguishing facilities with construction companies, supervisors, and business partners.Third, in the case of emergency alarm measures, statistical attention was paid to the application of emergency alarm sound to temporary broadcasting facilities with construction works, supervisors, and business partners.Fourth, in the case of induction, statistical attention was paid to the application of connection between construction works, supervisors, and partner workers, such as passage guidance, emergency lighting, etc.It was found that 65% of construction workers and 55% of electrical workers had different applications such as aisle guidance and emergency lighting for each type of business partner. In order to resolve blind spots such as evacuation zone guidance due to the structure of the building, it is necessary to easily distinguish the direction of the entrance door from a long distance by applying it in conjunction with passage guidance lights and emergency lighting.

화재가 발생했을 때 많은 사람이 연기에 질식하여 사망하는 피해가 거의 해마다 일어나고 있다. 특히 올해 2월18일 190여명이 사망한 대구 지하철 중앙로역 화재참사에서는 다량의 유독성 가스를 효과적으로 배출하지 못해 더 많은 사망자가 발생하였다. 당시 지하철역에는 화재가 발생하면 환기용 배기장치가 급기장치로 전환되는 급기방식의 제연설비가 설치되어 있었고, 시계 불량으로 피난 표지판과 유도등이 잘 보이지 않은 것으로 밝혀졌다.(중략)

Government and company are unfolding greenhouse gas reduction activity to prevent the effects of global warming. Also, verification business through greenhouse gas inventory construction is spreaded variously. Greenhouse gas verification proceeds by document examination, risk analysis, field survey. Document investigates emission information, calculation standard, emission report, data management system. And through risk assessment result, establish field verification plan. Through study on risk assessment of greenhouse gas inventory verification, wish to reduce risk of verification.
