구조물의 대형화, 고층화에 따라 화재로 인한 인명피해 및 물적피해가 증가하고 있다. 최근 10년간의 인명피해 중 사망자는 매년 평균 6.3% 증가하였고, 부상자의 년평균 증가율은 5.1%로, 2002년에만 531명의 사망자와 1,853명의 부상자가 발생하였다. 2002 년 한 해 동안 34,000여건의 화재가 발생하였으며 이 가운데 건물화재는 약 80%를 차지하고 있다. 인명피해는 대부분 건물화재에서 발생하였으며, 불연내장재의 사용증가에 따라 화염 및 영에 의한 화상 등의 직접적인 피해보다는 일산화탄소 중독이나 질식사 같은 연소가스에 의한 피해가 증가하는 추세이다.(중략)

최근 수도권에서는 지방공단 등으로 이전한 노후 공장 건축물을 철거한 자리에 '테크노타운', '벤처타운', 'IT타워', '디지털밸리', '테크노밸리' 등의 이름으로 아파트형 공장을 설립하고 있다. 아파트형 공장은 서울을 중심으로 수도권역에서 토지이용을 극대화가기 위한 집합 공장건물로서 중소기업체의 입지 해결 및 쾌적한 작업환경을 제공하고 도시근로자의 풍부한 노동력을 적극적으로 활용하고 있다. 또한 공동 부대시설을 확보하여 공간효율의 극대화와 종업원의 복리후생이 개선되는 등의 중소기업 지원효과를 거두고 있다. 고층화, 집단화, 공동화를 주요 특징으로 하는 아파트형 공장에서 부속시설의 화재보험요율 적용에 관하여 생각해보고자 한다.

This research was done to develop a duct-dedicated intelligent fire detection system to prevent fires and minimize fire damage of the industrial duct having a high fire risk. To understand the fire hazards of the ducts, the analysis was centered on the Daegu Textile Industrial Complex, where industrial ducts are used frequently. With this in the background, dedicated fire detectors and fire alarm control panel, which can prevent fires and to minimize fire damages to the ducts, were designed and produced, after which the performance was confirmed. As a result of performance experiments, it was shown that a duct-dedicated intelligent fire detection system had excellent adaptability and temperature accuracy. Through real-time temperature monitoring of the inside of the ducts, it was confirmed that duct fires could be efficiently extinguished by stepwise control of linkage facilities according to the setting temperature.

In order to investigate the smoke movement in three dimensional room fires, the center fire, wall fire and corner fire plume in different sized fires were studied experimentally by rectangular pool fire using methanol as a fuel. As the fire size became larger for the center fires placed at the center of the floor, the air flow rate entrained through the opening, average hot layer temperature, flame angle deflected backwards and mean flame height was observed to increase. On the other hand, as the fire size became smaller, the neutral plane height in the door and time reached steady-state was observed to decrease. The average hot layer temperature, mean flame height and doorway neutral plane height obtained from comer fire were higher than those produced by wall fires and center fires. The simple model for describing the effect of walls on the mean flame height was presented. It was shown that the model provides a good description of the present measurements, when used with the assumption by Hansell(1993), that the increase of the average flame height is equal to the ratio of the open to the total perimeters of the trays. Also the two models for predicting the effects of walls on the mean flame height were presented. These models overestimated the measured values of the mean flame height above fuel trays close to a wall and in a corner by approximately 19-26%, respectively.

본 연구는 최근 발생한 숭례문 화재와 같은 목조문화재의 화재를 초기에 인지하고 확인하는 차원에서 고안된 시스템으로써 불꽃감지기와 같은 초기 화재 감지시스템의 오작동 여부를 확인하여 화재감지기의 오작동으로 인한 경제적 시간적인 손실을 예방하고 목조문화재를 화재로부터 보호하기 위한 시스템이다. 초기에 화재를 감지하는 불꽃감지기는 현재 목조문화재뿐만 아니라 다양한 곳에서 활용되고 있지만 감지기의 오작동 및 오류를 확인하는 시스템은 실제로 실효성 등의 문제로 인해 활용이 미비한 실정이다. 본 연구에서는 유비쿼터스 센서 네트워크(USN) 기술, 불꽃감지기, 이미지 센서, USN 기반 문화재 방재 응용사례, 오작동 확인시스템 구현 등에 대해서 살펴보고 유비쿼터스형 문화재 방재시스템을 제시해 본다.

To measure the full scale fire test and heat release rate of bed mattresses according to the building compartment space, a fire test was performed using the Standard test method to determine the heat release rate of mattresses and mattress sets (KS F ISO 12949: 2011). Both test locations showed similar fire growth until approximately 3 minutes after burner ignition. After 3 minutes, the heat release rate in the test room was higher than the open calorimeter. For bed mattresses (SS), the maximum heat release rate in the open calorimeter was 735 kW and the maximum heat release rate in the test room was 992 kW. For bed mattresses (Q), the heat release rate in the test room increased more rapidly than the open calorimeter. The maximum heat release rate in the open calorimeter was 1,087 kW (346 s) and the maximum heat release rate in the test room was 2,127 kW (287 s). The difference between the maximum heat release rate and the measurement time according to the test location was confirmed.

A sports center fire in Jecheon caused 29 deaths and 40 injuries. This study focused only on the structural factors of the building and equipment to investigate the causes of casualties based on the fire investigation results at the sports center. The structural factors of the building and equipment were a piloti-type parking lot, lack of a fire compartment between the piloti-type parking lot and lobby, lack of an installed sprinkler system, lack of an installed fire door in the main stairs on the $1^{st}$ floor, lack of an installed fire water tank on the rooftop, an installed pocket fire door in the main entrance on the $2^{nd}$ floor, poor fire compartments in an EPS space and a pipe pit and on each floor, a leak in the joint of a drain pipe, plywood installed in the hoistway of the freight elevator and interior wall, illegal remodeling of a closed rooftop structure, which cannot discharge smoke and heat, installed styrofoam insulation in the inside of the parking lot ceiling, an installed tempered glass window, which cannot be opened in the ladies bathroom on the $2^{nd}$ floor, and a finished dryvit exterior wall.

Pilotis are support columns that lift a building above the ground. Thus, they can elevate the lowest floor to the secondfloor level and, in Korea, are used to leav a parking area below multifamily housing. However, if there is a fire in the piloti area, the cars and main entrance door are wrapped in flames. Due to the inflammability of the materials, the combustion of the cars and insulation at the ceiling of the pilotis, having a high heat release rate, can quickly destroy the front entrance of the building and spread heat, flames and a poisonous gas to the stairs and elevator pit. Therefore, the fire can quickly spread to the whole building, putting the lives of the residents in danger. This study was an in-depth accidental case study of the "Uijeongbu Fire Accident" that killed 5 residents and injured 139 others. The study identified the relationships between the fire at the piloti structure of multifamily housing and the vulnerability of this structure and its inherent weaknesses.

The wooden cultural assets have the characteristics such as the fast spread of flame and leading to total destruction. Therefore, there is a need for a system for early countermeasure of recognized problem, along with the technological response for accurately recognizing the situation, for the prevention and early suppression of fire. To utilize such technology for detecting the situation through the latest ubiquitous technology and for a quick response to suppress fire, the ubiquitous sensor network (USN) technology, flame detector, image sensor, USN-based cultural asset disaster prevention management application case and malfunction identification system realization were examined in this study and the study result was presented focusing on the flame detector malfunction identification system for the ubiquitous-type cultural asset disaster prevention system.
