  • Due to the cases of recent global warming and unusual weather etc., large-scale natural disasters such as typhoons, floods, snow damage occur frequently across the continents such as Southeast Asia and North America, South America etc. and risks of earthquakes and tsunami are also increasing gradually in Korea which has been regarded as a safe zone and disaster types are also being diversified such as typhoons, floods, heat waves, heavy snow and damage scale is also enlarged. In addition, due to geographical characteristics or lack of infrastructure, disasters tended to occur intensively around a specific region or city in the past but disasters occur throughout the country in recent years so preparation for disaster prevention has emerged as an urgent challenge issue. Therefore, considering that the plan of obtaining the effective feedback function of disaster Information is very important in the proactive and software aspects for disaster reduction, this paper analyzed this three aspects of contents, procedural and contextual aspects and proposed the plan. First, in the content aspect, building disaster prevention information communication Infrastructure, building urban and regional disaster prevention system, obtaining concurrency and sharing of information and second, in the procedural aspect, active utilization of ICT(Information and Communication Technology) of the prevention stage, disaster prevention information collection and analysis reinforcement of the preparation stage, improvement of decision-making structure and field command system of the response stage, recovery system related information promotion of the recovery stage were proposed as alternatives and finally, in the contextual aspect, if disaster prevention information is effectively managed through maintenance of disaster prevention information related systems, obtaining domainality by disaster prevention work, improvement of the ability to judge the situation, obtaining comprehensive and feedback function etc, it is considered to significantly contribute to reducing natural disasters.

  • The building infrastructures such as high-rise buildings, shopping malls, exhibition centers, etc. are becoming larger in magnitude and more complex in complexity. Considering a large number of tenants and visitors are staying in these facilities, it is upper most important to keep those in safe from fire outbreak. In this paper, a u-Disaster Prevention System has been presented to provide effective fire evacuation when fire breaks out in building infrastructures. The ubiquitous sensor network (USN) technology was applied to detect heat and smoke from fire outbreak. The information then is transmitted wirelessly to a host computer. The tenants and visitors residing in the facility can evacuate following the instruction that is displayed in LED sign boards of the u-Disaster Prevention System. A case study shows that the ubiquitous environment can help people evacuate faster in time, shorter in distance with the assistance of the u-Disaster Prevention System.

  • In the case that high-rise building is constructed, the surrounding wind velocity increase more than 50~100%. From this cause, many wind environmental problems can be occurred. For example, ordinary wind environmental disaster may be occurred in a region, or walking disturbed. In developed countries including USA, EU, and Japan, many efforts have been made for building wind prevention by grasping previously the effects before building constructed. But, We are bearing risk of wind environmental disaster because we have not enough recognition about building wind, and have not architectural prevention counterplans. This study aims to examine wind environmental characteristics of domestic apartment complex, and effective architectural counterplans. As the basic stage for this, we investigated pre-estimate tools and risk assessment methods of building wind in apartment complex, applied to two apart complex in Cheon-An region by CFD. As the result, serious damages were not presented. But, it is obvious that various architectural counterplans will be presented by this example researches.

  • Disaster Safety Management Information standardization and harmonization simplifies the process of disaster management (prevention, preparedness, response and recovery) to increase the efficiency of disaster management, it is necessary to minimize the people's life and property damage. Disaster safety standardization is to standardize disaster safety information in the past to respond to an uncertain future and systematically manage disaster safety accordingly. This study developed a standard code system to utilize disaster safety information such as earthquake, fire, and fine dust, which are of social interest among various and complex environmental disasters. It aims to support practitioners to conduct efficient disaster tasks in the event of a disaster.

  • 본 연구는 건축물 화재성상 시뮬레이션 개발을 위한 기초 연구 자료로서 건축물 화재시 높은 비중의 가연물과 좁은 이격거리로 인하여 화재 발생시 급격히 연소확대될 위험성이 높고, 개구분출화염이 건물 화재확산의 중요한 요인이나 이 분야에 대한 연구는 부족한 실정이며, 또한 화재성상 예측시 기존 시뮬레이션에서 화재확산의 중요한 인자인 바람의 요소가 고려되지 않았다. 이에 대하여 개구분출 실물화재실험을 통하여 유풍시 개구분출화염에 기인한 수식을 도출하였으며, 이를 기반으로 향후 기존의 바람 인자를 고려하지 않은 화재성상 예측 시뮬레이션에 적용 가능성을 모색하여 국내 실정에 맞는 화재 성상 시뮬레이션 개발 구축에 대한 기초자료로 제시한다.

  • 본 연구는 건축구조물의 내장재 및 실내장식물 등의 연소 성상 DB를 바탕으로 화재 성상을 예측할 수 있는 기존 모델인 칼슨모델(B.Karlsson) 및 퀸티어리모델(J.G.Quintiere)을 비교, 분석하여 그 절차 및 차이점 등을 분석한 후 국내 가연물 연소성상 DB를 토대로 개구조건 및 건물구조 등을 고려한 화재성상 시뮬레이터 개발을 위한 기초 조사 자료이다. 조사 결과 칼슨모델과 퀸티어리모델의 차이점은 우선 초기 착화영역과 착화의 판단 및 연소면적 등에서 차이가 있었으며 향후 이를 기초로 실험 결과와 대비를 통한 분석을 수행 할 예정이다.

  • 최근 건축물은 초고층화의 경향을 보이고 있으며 이에 따라 하중감소 및 에너지 절약을 위한 외장재를 사용하고 있으나 화재 안전성은 고려되지 않아 화재 위험성이 증가되고 있다. 또한 높은 층수에 의한 바람의 영향이 증가하여 화재 시 큰 변수로 작용될 위험성이 있다고 판단되었다. 이에 초고층에서의 화재 안전과 관련 규정이 추진되고 있으나 여전히 미흡한 실정이며 화재 안전 대책이 강구되고 있다. 이에 본 연구에서는 초고층건축물의 화재 시 외장재와 바람이 화재 성상에 미치는 영향을 알아보고자 2010년 부산에서 발생한 초고층 주상복합건축물의 화재 사고를 FDS를 통해 분석한 결과, 화재 시 풍속을 적용한 경우가 적용하지 않은 경우에 비해 빠른 수직, 수평 화염 확대를 보였으며, 높은 최대 HRR값을 보였다.

  • TThe cooperation on disaster prevention between the two Koreas has been mostly focused on cooperation at the recovery stage, such as emergency relief supplies and equipment support. This study aims to articulate future practical development plans by analyzing disaster cooperation between North and South Korea in accordance with the changing paradigm of international disaster cooperation. Considering the specificity of inter-Korean cooperation, the Framework for Inter-Korean Disaster Prevention Cooperation was established centering on the Sendai Framework for Disaster Risk Reduction. The framework consists of understanding and sharing disaster risks, building back better, strengthening community resilience, and supporting regional disaster action plans for continuous action. Inter-Korean disaster prevention cooperation requires sharing information about North Korean disasters. It is necessary to accurately identify and support social vulnerability to North Korean disasters. Above all, it is supporting the development of disaster action plans from a humanitarian perspective needs. A medium-to-long term resilience reinforcement plan that North Korea can resolve on its own is also needed. Since North Korea is also deeply interested in international disaster cooperation, it should be based on the direction of the Sendai Framework. Considering the uniqueness of inter-Korean cooperation, a path for North Korea to actively participate in international disaster cooperation should be established.

  • 최근 건축물에서 공동주택의 비율이 증가하고 있으며 동시에 공동주택의 화재비율도 증가하는 경향을 보이고 있다. 또한 화재 시 인명 피해의 주원인인 가연물은 소재가 다양화되고 있으나 안정성 보다는 디자인, 기능성에 치중되어 그에 따른 화재 위험성도 커져가고 있다. 따라서 본 연구는 전보의 실내장식물에 이어 공동주택에서 많이 사용되어지는 적재가연물을 가연물 조사를 바탕으로 선정하여 Furniture Calorimeter를 이용해 그 연소특성을 알아보았다. 그 결과, 소파가 타 시료에 비해 화재 시 높은 위험성을 나타냈으며, 일본건축학회에 발표된 데이터와 비교한 결과 소파의 데이터가 유사한 것으로 나타났다.

  • This study analyzed the effect of zoning on the distribution of pressure differentials caused by stack effect and air pressurization in a center core type of 80 story super-tall building. The results showed that maximum pressure difference more than 250 Pa can be generated by stack effect without zoning. Zoning of stairwell only resulted in 10 Pa reduction of maximum pressure difference, however, zoning of both stairwell and EV shaft especially at the same floor revealed 50 % reduction in stack effect. It was also analysed that the minimum required air flow rate occurred when the stairwell temperature reached 50 % of temperature difference between indoor and outdoor.
