In recent Korean society, as suicide rate has greatly increased during the last decade, religions have also become seriously concerned for the problem of suicide. There recognition of suicide, however, was not always the same. This article elucidates why religious people came to have different recognition of suicide. For this, firstly, I analyse religions’ cooperative campaigns for suicide prevention. There was two sorts of the campaign: One is the campaign by the progressive religious group, and the other by the conservative religious group. The former regard suicide as a social-and-spiritual problem and, therefore, layed more stress on the social justice. For the latter, on the contrary, suicide was mere a personal-and-spiritual problem and, therefore, each person’s awareness of the pathology and fault of suicide was more emphasized. This shows that religious people’s recognition of suicide is determined not so much by religious belief as by political opinion. Secondly, I analyse two cases of religiously motivated suicide that happened in 2010, which showed both similarities and differences. The first case is Munsu, a Buddhist monk, who burnt himself to death in order to demand the President to stop the development work destroying living things. Another is a man known as “Mr. Lee,” who thought himself the incarnation of Highly God and killed himself in order to ascend to heaven where he should fight against evil gods. While Munsu’s suicide has been commemorated as a religious-and-political self-immolation both by the Buddhist community and by the progressive political camp, Mr. Lee’s suicide was soon and completely forgotten from the memory of most people. Reading Munsu’s suicide note and Mr. Lee’s diary, we can see that Munsu was worried about the suffering of living things on earth and that Mr. Lee was anxious for the suffering of spiritual beings in heaven. Reading more closely Mr. Lee’s diary, however, little difference is found between his and Munsu’s altruistic compassion for other beings. Therefore, what makes them different was not their belief or practice but the signifying behavior of the community who remembers the dead. Through such analyses, in conclusion, we can say that the relation between suicide and religion is not fixed but fluctuates according to political and communal situations.

In general, when a building fire occurs, the heat flow rises by buoyancy, which affects the temperature rise of the ceiling. In addition, when the ceiling ignites, the fire spreads rapidly due to horizontal spread and radiant heat. According to the fire investigation, most of the large fires have a common characteristic that the fire spreads to the ceiling and causes many casualties. Therefore, it is considered that it is necessary to review the fire risk of ceiling materials used in buildings to prevent the spread of fire to the ceiling. Therefore, in this study, combustion characteristics such as the amount of heat released and ignition time of each SMC, DMC, and gypsum board were checked using a Cone Calorimeter, and the ignition temperature was calculated by substituting them into the fire theory. As a result, the ignition temperature of SMC was 449K, that of DMC was 1492K, and that of gypsum board was 677K.
화재 시 고층건축물의 연돌효과에 따른 압력차 분석에 관한 연구

국내의 고층건축물이 지속적으로 증가되어 감에 따라 연돌효과와 관련한 관심이 대두되고 있다. 특히 화재 시에는 실내의 온도가 높아지면서 연돌효과가 커지는 문제가 발생하고 있다. 이에 따라 화재 시 온도변화에 따른 연돌효과의 영향을 분석해야할 필요가 있다고 판단된다. 본 연구에서는 CONTAMW시뮬레이션을 이용하여 개구부의 개폐여부와 화재가 발생하여 화재실의 온도가 성장기의 온도로 상승한 경우를 설정하여 화재 시 온도상승에 따른 건축물 내의 압력차를 확인하였다. 그 결과 개구부의 개폐여부에 따라서는 개방 시에는 0~100 Pa 정도로 각 층마다 균일한 압력차를 보였다. 하지만 화재실을 가정하였을 때는 화재층의 압력이 250 Pa 정도로 높아지며;각 층마다 압력차의 변동이 큰 것으로 확인되었다. As the number of high-rise buildings in Korea continues to increase;interest in the stack effect is increasing. In particular;in the event of a fire;as the indoor temperature increases;there is the problem that the stack effect increases. Accordingly;it is necessary to analyze the stack effect resulting from temperature change during a fire. In this study;by using CONTAMW simulation;the opening was opened or closed. In the case where the temperature of the fire room rises to the temperature of the growth period caused by a fire;the pressure difference in the building according to the temperature increase during a fire was confirmed. As a result;depending on whether the opening was opened or closed;the pressure difference was uniform for each layer;ranging from 0 to 100 Pa when opened. However;assuming a fire room;the pressure in the fire layer increased to approximately 250 Pa;and it was confirmed that the pressure difference varied greatly for each floor.

2017년 제천스포츠센터 화재로 인하여 약 80명의 사상자가 발생하였다. 특히 2층과 3층에서 화재피해 형태가 상이하게 발생해 일반적인 화재사례와 차이점이 나타났다. 이후 발간된 화재백서 및 보고서 등에서는 주요 화재확산경로를 화물용 승강기로 추정하고 있다. 그러나 화재로 인한 소손 피해, CCTV 및 재실자 증언 등의 자료에 따르면 화물용 승강기가 2층과 3층에서 상이한 피해를 야기한 화재확산경로가 아닐 수 있다는 것을 시사한다. 따라서 본 연구에서는 화재확산 경로를 명확히 추정하기 위하여 화재사례 및 화재시뮬레이션을 비교하였다. 그 결과 화물용 승강기보다 주 계단이 주요 화재확산경로로서 더욱 신빙성이 있는 것으로 나타났다. In 2017, a fire at the Jecheon Sports Center resulted in approximately 80 casualties. Interestingly, the extent of fire damage on the second and third floors differed from the general type of fire damage. The white papers and reports of the Jecheon Fire Department indicated that the primary spread path of the fire was a freight elevator. However, analysis of the damage caused, CCTV footage, and victim testimonies suggested that the freight elevator may not have been the primary fire spread path on the second and third floors. Therefore, further investigation was needed to identify the cause of the fire. In this study, fire simulations were conducted using a Fire Dynamics Simulator (FDS) and compared with actual fire cases, which enabled us to predict the fire spread path accurately. It was found that the main stairway was more likely to have been the main fire spread path than the freight elevator.

본 논문에서는 물류창고의 자연배연을 위하여 한⋅일의 법령과 일본의 설계지침에서 제공되는 설계법을 조사하고 이를 통해 수용품 특성, 건축물 특성에 따른 배연설비 유효면적을 산정하였다. 그 결과, 양국의 법적 기준을 통한 유효면적은 10 m2, 20 m2로 산정되었고, 일본 지침을 통한 결과는 7~16 m의 층고에서 CUP를 수용한 공간은 24.71 m2부터 13.76 m2, CEP를 수용한 공간은 41.83 m2부터 22.54 m2로 산정되었다. 이렇게 산정된 유효면적을 통해 배출되는 배연량의 경우, 국내 법적기준을 적용한 경우는 모든 Case에서 플륨유량보다 배연량이 적었다. 일본 기준을 적용한 경우는 CUP 적재창고에서는 9 m부터 16 m까지는 연기발생량보다 배연량이 많은 배연효율을 냈으나 7 m부터 8 m에서는 배연량이 더 적었다. 지침을 적용한 유효면적에서는 모든 Case에서 연기배출량이 연기발생량보다 많았다. This study investigated the design methodologies outlined in Korean and Japanese legislation, along with Japanese design guidelines, pertaining to natural smoke ventilation systems in logistics warehouses. Subsequently, we determined the effective area of the smoke exhaust system based on the combustible materials and building characteristics. Our findings indicated that the calculated effective area per the statutory standards of both nations was 10 m2 and 20 m2, respectively. According to Japanese guidelines, the space accommodating the CUP ranged from 24.71 m2 to 13.76 m2 for floor heights between 7 to 16 m, while the space accommodating CEP ranged from 41.83 m2 to 22.54 m2. Analyzing the quantity of smoke emitted through the calculated effective area, we observed that, when applying domestic legal standards, the smoke exhaust rate consistently remained lower than the plume flow rate. Conversely, under the Japanese standard, the smoke emission efficiency of the CUP loading warehouse surpassed that of smoke emission from 9 m to 16 m, while it was lower from 7 m to 8 m. Notably, the smoke exhaust rate consistently exceeded the generated smoke quantity in all instances within the effective area governed by the guidelines.
