Development of the economy and the growing income of people interested in the leisure and health has been focused. Past the town common wells and groundwater around the water, but health is a priority these days to solve the drinking water directly from tap water, but most people work from home, through the water purifier has been resolved. Depending on seasonal changes and personal taste of coffee, if you can enjoy a snack and water purifier is a restaurant, lounge, public areas and focusing on the rapid spread of the fire, water purifier as compared to the total number of fires increased by 0.03% per year trend on, but the washrooms fire and fire-related research data and case studies with analysis of the exact cause lack of proper preventive measures are insufficient reality. In this study, focusing on electrical energy using a water cooler to understand the structure and principles of fire, the fire revealed the mechanism is vulnerable to the consideration of factors, the exact cause of the fire investigation and the Assistant, manufacturing defects, and to contribute to fire prevention review should.

Recently, the buildings have gradually become higher, more massive and more complex with high growth of economy and varieties of the patterns of people's living. Therefore we study a performance and Improving Methods of the fire compartment as a measure to minimize the damage of the people and property from the fire. Currently, under the economic crisis situation, we do not consider about prevention of disaster safety enough; safety investment evasion, safety carelessness, and management relaxation etc. Also in the aspect of regulation system, industrial technology and plan engineering, Korean techniques of preventing fire disasters are far behind of other advanced nations. At this point, we are in need of improving about it. When considering like this situation, we need more studies on the practical improvement in order to assure fire prevention for buildings. The fire compartment prevent from magnifying the fire to the wide area by compartment into specific area. From this, it is possible to minimize fire damage and property and secure emergency exit for life safety. This fire compartment has primary function to extinguish fire easily, and the openings and penetrations are important passage which makes the smoke and fire go away from the fire area to the contiguous space. This study suggests improving methods of domestic fire compartment efficiency standard through comparative analysis of overseas advanced provision and domestic provision about base element of the building fire prevention.

In the past, the risk of fire and the rate of fire occurrence has increased gradually as the quality of life improved due to rapid economic growth, and the government enacted Fire Prevention Act. The existing inspection method was revised considering the rapid increase in the number of fire-fighting objects(hereinafter referred to as specific fire-fighting objects) that require the installation of fire-fighting facilities, and has been applied to this day. On the other hand, unlike the rapid increase in specific fire-fighting objects and the development of fire prevention technologies, the scope of work and inspections by unsuitable inspectors caused a large fire accident, which required improvement of the related laws. This study evaluated, the Act on the relationship of firefighting facilities, which had been implemented previously to identify fire victims, save lives, secure independence of fire inspection agencies, and ensure the accuracy of fire prevention actions.

Magnesium fires require early fire extinguishment due to impulsive and rapid-fire expansion that makes difficult fire fighting. For this reason, efficient early fire fighting and appropriate prevention of fire spread are considered mainly as significant fire extinction measures. However, there is a limit to developing tools for metal fire fighting, such as devices, facilities, and fire extinguishing agents, due to a lack of regulatory instruments in South Korea. It often generates challenges to early fire fighting implementation by fire responders. Thus, the aim of this study is to investigate a measure for securing the efficiency of early fire fighting in magnesium. This study identified the applicability of the metal fire extinguisher used in the United States for magnesium fire through a performance test of a fire extinguishing agent for metal fire. Moreover, we implemented a free burning experiment using magnesium powder to compare varying combustion and extinction process that could occur during applying metal fire extinguishers. Finally, this study suggests measures of the use and application of metal fire extinguishers for magnesium.

In order to investigate the strength recovery of fire-damaged concrete after post-fire curing, concrete specimens were heating at $2^{\circ}C/min$ or $5^{\circ}C/min$ to 400, 600 and $800^{\circ}C$, and these exposed specimens were soaked in the water for 24 hours and following by 29-day post-fire curing. The compressive strength and split tensile strength of the high-temperature-exposed specimens before and after post-fire curing were tested. The proportion of split aggregate in the split surfaces was analyzed to evaluate the mortar-aggregate interfacial strength. After the post-fire curing process, the split tensile strength of specimens exposed to all temperatures was recovered significantly, while the recovery of compressive strength was only obvious within the specimens exposed to $600^{\circ}C$. The tensile strength is more sensitive to the mortar-aggregate interfacial cracks, which caused that the split tensile strength decreased more after high-temperature exposure and recovery more after post-fire curing than the compressive strength. The mortar-aggregate interfacial strength also showed remarkable recovery after post-fire curing, and it contributed to the recovery of split tensile strength.

Smoke and fire spread throughout the building as a result of problems in the fire prevention section of Uijeongbu Apartment Fire in 2015 and Jecheon Sports Center Fire in 2017 in Korea, causing a number of casualties. It is believed that the fire compartment standards need to be reviewed as the fire in recent buildings continues to show problems. In this study, a comparative analysis was conducted on the fire prevention zone standard with Japan to improve the fire compartmente standard in Korea.

화재는 콘크리트 구조물의 역학적 특성에 치명적 손상을 일으켜 건축물의 안전성을 급격하게 감소시킬 수 있다. 특히 고강도콘크리트는 폭렬이 발생하여 심각한 단면 손실과 노출된 철근으로 인하여 건축물의 안전성에 치명적인 영향을 미친다. 이러한 폭렬에 대하여 다양한 연구가 진행되고 있지만, 폭렬의 발생원인은 명백하게 밝혀지진 않았다. 이에 본 연구는 콘크리트의 함수율과 열응력이 폭렬에 미치는 영향을 분석하여 폭렬로부터 구조물의 안전성을 확보하기 위한 기초 자료를 제시하였다.

본 논문은 초고강도콘크리트의 폭렬현상을 연구해 보고자 실리카흄 유무와 PP섬유의 혼입량을 변수로 하여 공시체와 벽체의 폭렬현상을 관찰한 후 변수가 초고강도콘크리트에 어떠한 영향을 주는지를 실험적으로 규명하는 것을 목적으로 하였다. KS F 2257 화재온도이력곡선을 30분 적용하여 콘크리트의 초기 폭렬특성을 실험적으로 검토하였다. 그 결과 공시체의 경우 압축강도가 100 MPa 초고강도콘크리트의 경우에는 실리카흄 여부와 PP섬유 혼입량이 폭렬억제에 관계되는 주요 인자인 것을 알 수 있었으며, 벽체의 경우에는 벽체 시험체의 부분 가열 및 전면 가열 실험을 실시했다. 폭렬 최대 깊이, 시간, 소리 발생 회수를 비교하면 부분 가열이 전체 가열에 비해 폭렬이 빠르고 깊게 발생하는 것으로 나타났다.
