  • The purpose of this study is to propose a quantitative toxicity endpoint distance suitable for the initial response of firefighters by comparing and analyzing the commonly applied toxic level of concern (T-LOC), specifically emergency response planning guidelines (ERPG), acute exposure guideline levels (AEGL), and immediately dangerous to life or health (IDLH). This is to protect the fire brigade, which responds to toxic chemical accidents first during the golden time. Using areal locations of hazardous atmospheres, a damage prediction program, the amount of leakage for both acidic and basic substances, along with the endpoint distance, were analyzed for alternative accident and worst-case accident scenarios. The results showed that the toxicity endpoint distance, serving as a compromise between Level-3 and Level-2 of T-LOC, was longer than ERPG-3 and shorter than ERPG-2 with IDLH, while its values were analyzed in the order of ERPG-2, AEGL-2, IDLH, AEGL-3, and ERPG-3. It is suggested that the application of IDLH in an emergency (red card) and ERPG-2 endpoint distance in a non-emergency (non-red card) can be utilized for the initial response of the fire brigade.

  • 12 typical laminated composite reinforced concrete (RC) walls with different concrete ages and 3 cast-in-place RC walls subjected to low frequency cyclic load were carried out in this study. The failure mode, force-deformation response and energy dissipation capacity of these specimens were investigated. Differences of structural behaviours between composite RC walls and common cast-in-place RC walls were emphasized in the analysis. The compatibility of the composite specimens with different concrete ages was discussed based on the experiment. Test results indicated that the differences between the lateral bearing capacity and the displacement ductility of the composite walls and the common walls were not so obvious. Some of the composite specimen even has higher bearing capacity under the experiment loading situation. Besides, the two parts of the laminated composite specimens demonstrates incompatibility at the later loading sequence on failure mode and strain response when it is in tension. Finally, this laminated composite shear walls are suggested to be applied in rapid reconstruction structures which is not very high.

  • 최근 우리나라는 사회경제적 발전과 본격적인 고도기술사회로 진입하였다. 그러나, 재난에 대응하는 개인의 능력은 사회의 복접성 증가로 낮아지고 있다. 재난 발생 시 개인이 파악할 수 있는 정보의 한계로, 정확한 상황판단 및 재난대응이 어려워졌다. 지금까지는 일반 스피커를 활용한 재난경보방송을 하였다. 그러나 일반 스피커는 음의 반사에 의한 잔향음, 음의 감쇠현상 등에 의하여 명료한 음의 청취가 어려웠다. 이러한 문제점을 해결하기 위하여 음이 직진하는 특성과 음의 감쇠가 없는 지향성스피커를 활용하여 구난자에게 재난발생 상황 및 피난에 유효한 정보들을 효과적으로 제공할 수 있는 방안에 대하여 제안한다.

  • In recent years after the Sewol Sank, the surroundings of Fire have rapidly changed and citizens need for Fire have been demanding very high. Under these situations, in order for satisfaction to all these demands, Seoul Metropolitan Fire & Disaster Headquarters(SMFDH) have made improvements of Golden Time in the field of disaster as the leader of Fire Department in Korea. SMFDH has been practicing many kinds of plans, or projects to achieve Gold Time of 55 types of disaster. However, There have been questioning about all these projects if they are working for the achievement. The purpose of this study is to scrutinize current projects for Golden Time Targeting focused on Mapo fire fighters as first responders and to cope with how to make them better for Seoul Citizens' safety by using SPSS(Statistical Package for the Social Science) Statistics 24. The result of this study presents that how we can find to be all the project for Golden Time Targeting running well. And This study will be positively applied to Seoul fire policies or helped for setting them up better.

  • Purpose: This study was conducted to develop the contents of disaster nursing education in community health nursing at universities. Methods: To validate contents, the Delphi method was used. We categorized two domains(indirect disaster management and direct disaster management) and developed 48 draft items. This study applied two round surveys and 23 experts participated in this study. The content validity was calculated using content validity ratio and coefficient of variation. Results: Indirect disaster management domain was composed of three categories including 12 items: 1) Understanding of the disaster, 2) disaster management system, and 3) response by disaster stage and recovery. Direct disaster management domain was composed of nine categories including 30 items: 1) Ethical considerations, 2) communication in disasters, 3) nursing activity by disaster stage, 4) emergency nursing in disasters, 5) patient severity classification in disasters, 6) disaster nursing for vulnerable groups, 7) disaster nursing for victims, 8) psychosocial nursing and health in disasters, and 9) cases of disaster nursing in communities. Conclusion: This Delphi study identified the contents of disaster nursing education curriculum, and confirmed the validity for disaster education program in community health nursing. Based on the results, it will be helpful for training the disaster nursing and improving the competency on disaster nursing of the nursing students.

  • In view of the importance of the wind-structure interaction for tall and slender structures, an aeroelastic model test of the 610m-high TV tower with a complex and unique structural configuration and appearance carried out successfully. The assembled aeroelastic model of the TV tower with complex shape and structure was designed and made to ensure the similarities of the major natural frequencies and the corresponding mode shapes. The simulation of the atmospheric boundary layer with higher turbulent intensity is presented. Since the displacement and acceleration responses at several measurement sections were directly measured in the wind tunnel test, a multi-mode approach was presented to indirectly estimate the displacement and acceleration responses at arbitrary structural floors based on the measured ones. It can be seen that it is remarkable for the displacement and acceleration responses of the TV tower in the two horizontal directions under wind loads and is small for the dynamic response of the torsional displacement and acceleration.

  • 재난의 대형화 복잡화가 진행되어 막대한 피해를 야기하는 대형재난의 발생하는 빈도가 높아짐에 따라 재난대비 및 대응을 위한 재난 및 안전교육이나 훈련의 중요성이 강조되고 있다. 본 연구에서는 재난안전교육이 재난의 위험도에 미치는 영향을 분석하였다. 위험도를 계산하기 위한 발생가능성과 재난의 결과에 재난안전교육이 미치는 저감효과를 전문가 설문조사를 이용하여 계산하였다. 교육대상을 세분화하여 저감효과가 달라짐을 확인하였으며, 이는 재난관련 업무 종사 공무원부터 초 중 고 학생들의 의무교육까지 전국민을 대상으로 적극적인 교육과 훈련을 실시할 경우, 최대 약48% 정도까지 재난위험도가 감소할 수 있을 것으로 조사되었다. 이에 대한 검증을 위해 실제 자료조사 및 분석과정이 수행되어야 할 것이지만, 이는 적극적인 재난안전교육을 실시해야만 하는 정당한 이유가 될 수 있을 것이다.

  • Recent research on stand-alone focused on the improvement and development of functions for solving problems such as the limited operating time of stand-alone installed at dwelling and their low reliability caused by false alarms, but it is more urgent to study on the operating range of stand-alone sensor in consideration of the impacts of combustion products on residents because the primary goal of fire safety is minimizing casualties. This study purposed to propose the optimized operating range of stand-alone sensor in consideration of the impacts of combustion products on residents. For this purpose, we made a mathematical approach to the change of temperature over the lapse of time in compartment fires similar to house fires, and established the standards of the body's response against heat and smoke based on literature review. In addition, we surveyed domestic and foreign technological standards for stand-alone sensor, and converted them to standards for residents of the body's response against heat and smoke using mathematical model equations and analyzed them comparatively.
