In this study, using the FDS as the fire simulation and evacuation simulations of the Pathfinder, set the main control room of the building to the fire point fire safety assessment studies were carried out. At first the quantitative result such as distribution of visibility as time passing, distribution of temperature, distribution of CO density produced results using fire-simulation and evacuation-simulation was carried out based on the result that produced the final safety evaluation result as being calculated of evacuation time. As the risk increased with the distribution of visibility at the result of fire-simulation, evacuation-simulation was carried out using the result. Finally the result was made 127.9 sec that everyone could evacuate. The numerical results are analyzed in case of the places in the building required safe egress time for safety a as the analysis to be no more than available safe egress time was analyzed to be secured. The results of this safety evaluation represent that more smooth evacuation safety performance can be secured by linking the event of fire firefighting equipment as a result of simulating the worst conditions.

In this paper, to make a base of the fire safety assessment about ship's fire protection design and Classification Society rule, statistical informations and modeling techniques for the fire safety engineering are investigated and probabilistic safety assessment methods in the structural reliability engineering are introduced. FSEM(Fire Safety Evaluation Module) developed in this paper calculates the probability of fatality, which can be used as an index of fire safety. FSEM is used to calculate the probability of fatality of the evacuees in a small room installed according to the rules for fire-proof. Sensitivity analysis is executed to investigate FSEM's applicability to ship. From results, the necessity of new criterion for ship's fire safety design, the need to study the human behavior in the evacuation from fire, and the development of new fire progress model considering special situations in ships are acknowledged.

국내의 화재로 인한 대형 인명피해를 보면 대부분이 직접적인 화재의 열에 의한 것이 아니라 연기유동을 통한 유해가스들의 흡입을 통하여 또는 대피시 재실자들 간의 사고로 인하여 생기는 것으로서 이글 방지하기 위한 대책이 시급한 상황이다. 이 대책으로써 무엇보다도 건물내의 방화관리자나 건물내 거주자들에 대한 직접적인 교육이 필요하나 건물의 대형화 및 재실자들의 불확실성으로 인하여 교육의 어려움과 무엇보다도 화재의 특성상 실제상황과 같은 구현을 통하여 교육하기에는 불가능 한 실정이다.(중략)

현재 전 세계적으로 태풍, 지진, 홍수 등의 재해 피해가 빈번히 일어나고 있고, 4차 산업의 발달로 인한 AI기술을 활용하여 자연재해 전반을 예측 할 수 있는 시스템이 도입될 정도로 과학적으로 발전 되어진 반면에, 재난으로 인한 인명 피해 수를 저감 시키는 방향을 도모 하는 데에는 어려움이 있고, 국민들의 재난피해의식도 심각 하지 않은 추세이다. 이와 같은 문제점을 파악하기 위해 한국 국민 남녀 489명을 대상으로 재난위험인식에 대한 설문을 작성하여 조사를 진행하였다. 본 연구의 목적은 국민들의 재난 안전의 위험도에 대한 인식 수준이 어떠한지 분석하고, 영향 요인을 탐색 하는 데에 있고, 조사결과 안전취약계층은 스스로 대피 하는 데에 있어 큰 어려움이 있으며, 이중 여성은 남성에 비해 안전교육과 훈련의 접근성이 적음에 따라 위험도가 더 큰 것을 확인 할 수 있었다. 본 연구를 통해 재난 안전교육의 필요성을 가지고 재난 안전 시뮬레이션 프로그램이 구축되는 필요성이 있다고 사료되어지고, 미래에 자연재해 발생 시 문제점을 파악하고 인명피해 감소가 될 전망으로 기대가 된다.

In this study, a formula was derived to calculate the damage impact distance using the Chemical Accident Response Information System (CARIS) so that local governments can decide on the evacuation and notification of 13 types of substances. The National Institute of Chemical Safety selected 16 out of 97 types of accident preparedness substances in 2018 and called them residents' evacuation preparedness substances. In a chemical accident, local governments should prepare for resident notification, such as emergency disaster texts. Using the CARIS in Chungju, this study modeled the damage-affected distances of 13 types of substances for the evacuation of residents. Under all conditions, the coefficient of determination R2 was 0.99 or higher, representing a range of at least 0.9921 to a maximum 0.9999. The relative standard deviation between the damage impact distance obtained using the calculation formula, and the CARIS result was compared. The minimum separation distance was corrected considering the actual chemical accident response situation, and the range was found to be between 0.58 and 5.97%. The damage impact distance can be calculated at the site using the calculation formula derived from the research, and local governments can determine whether to evacuate or notify residents.

Purpose: The purpose of the present study was to identify factors affecting anxiety about disaster damage potential in Gyonggi-do and evacuation behavior that influences evacuation behavior. Method: Multiple regression analysis was performed to test the hypothesis and to analyze the influence of anxiety about disaster damage potential and perceived stress, and analyzed similarity in correspondence between age and anxiety about disaster damage potential. Results: The anxiety about disaster damage potential of a group vulnerable to safety and anxiety about disaster damage potential of disaster system collapse were perceived in close proximity. Disaster system collapse, evacuation life, and natural disasters were found to be factors affecting perceived stress. Stress and natural disasters were found to be influencing factors on evacuation behavior. Conclusion: The necessity of managing stress was confirmed since anxiety about natural disaster damage potential and stress affect evacuation behavior. The recent experiences of heavy rain disasters indicate that the anxiety about disaster damage potential is expected to increase. The findings also indicate the importance of preventive planning and psychological management to manage the anxiety about disaster damage potential.

This study analyzed the causes of flood accidents, such as isolation and lost footing accidents in Dorimcheon, to provide legal and institutional improvements. For cause analysis, Field Investigation, Stakeholder Interview, Report, manual, Law et al. Review, Analysis of water level change characteristics, automatic alarm issuance standard level analysis, and evacuation time according to river control were evaluated. Dorimcheon has the characteristics of a typical urban river, which is disadvantageous in terms of water control. In addition, the risk of flood accidents is high because the section where fatal accidents occur forms sharply curved channels. Tripping and isolation accidents occur in the floodplain watch and evacuation stage, which is the stage before the flood watch and warning is issued. Because floodplain evacuation is issued only when the water level rises to the floodplain, an immediate response according to the rainfall forecast is essential. Furthermore, considering that the rate of water level rise is up to 2.62 cm/min in Sillimgyo 3 and Gwanakdorimgyo, sufficient evacuation time is not secured after the floodplain watch is issued. Considering that fatal accidents occurred 0.46 m below the standard water level for the flood watch, complete control is very important, such as blocking the entry of rivers to prevent accidents. Based on these results, four improvement measures were suggested, and it is expected to contribute to the prevention of Tripping and Isolation Accidents occurring in rivers.

In order to manage traffic operations efficiently, it is required to establish evacuation strategies, including path, disaster prevention, and signal control. This is because the delayed response of operators would cause dreadful loss of our community. Therefore, it is very important to do the research related to traffic disaster prevention system. In this paper, we select the City of Cheongju as a study area since lots of damage resulting from natural disaster such as storm and flood have been frequently taken place. In addition, this paper suggest traffic disaster prevention measures and analyzed its effect on signal operation to achieve high level of traffic efficiency. As a result, traffic flow is similar to normal condition when we applied developed signal operation method. It is also demonstrated if disaster information is spread out as fast as it can be, and signal operation is managed properly in case by case, we conclude that user safety has to be secured.
