  • 본 연구의 목적은 노인을 위한 소방안전교육 프로그램을 개발하고, 이 프로그램이 노인의 소방안전지식과 소방안전사고예방실천에 미치는 효과를 알아보는 것이다. 프로그램은 기초조사와 문헌고찰을 토대로 목적과 목표, 내용, 교수학습방법을 선정한 후 전문가 검증과 예비조사를 거쳐 개발하였다. 효과검증은 65세 이상 노인 48명을 실험군(노인을 위한 소방안전교육 프로그램 실시)과 대조군(인쇄된 강의자료만 제공)으로 나누어 비동등성 대조군 사전사후검사를 실시하였다. 각 집단의 사전-사후 검사점수를 대응표본 t-검증으로 분석한 결과, 프로그램을 실시한 실험군과 인쇄자료만 제공한 대조군 모두 사전-사후 점수 간에 통계적으로 유의미한 차이를 보였다. 그리고 공변량분석(ANCOVA) 결과 실험군의 사후검사 점수가 대조군의 사후검사 점수보다 높게 나타나, 인쇄자료에 비해 프로그램의 효과가 유의미하게 높음을 확인하였다.

  • AU(A plus U-shaped) composite beam was developed for reducing the story height in the residential buildings, and saving the cosrtuction cost of floor structures. Structural performance and economic feasibility of the composite beam have been sufficiently approved through the structural experiments and the analytical studies. Fire safety for the practical application of the composite beam has also been verified through the fire resistance tests and the heat transfer analyses. In this study 2-points bending tests were performed on the four specimens already tested for fire resistance to evaluate the residual bending strength of AU composite beam after fire accident. The same bending test was performed on the one fresh specimen having the same section and span of the specimens for practically comparative study.

  • Today's building and fire prevention codes are mostly prescriptive. Prescriptive codes are based on major fires in earlier years that created a need for specific building provision. These codes provide a minimum level of safety. As the general and engineering uses of computers have increased over the years, so has use of computers in the fire protection engineering. This has allowed fire protection engineers to develop alternative approaches to solve today's fire protection problems or to evaluate the performance of a specific fire safety goal. A performance based approach to building and fire codes involves the following: 1) identifying specific goals, such as, safely getting out of the building in 10 minutes, 2) obtain conceptual approval from authorities, 3) define performance level, 4) develop design solutions and identify tools such as, fire tests, models, or methods, to demonstrate that a design will meet the fire protection objective 5) test solutions, 6) present test method and results to the authorities. Some people in the fire protection community consider this to be nothing more than an intellectual exercise, while the others view it as a way to reduce expenses on large project$^4$ Others in fire protection community view this as a way to refine the design process to design fire protection systems to better protect the fire hazards. This paper will focus on application of these tools, specifically computer fire models, to actual cases such as: design of a smoke control system heat transfer analysis and egress of building occupants during potential fires.

  • 연구목적: 촛불화재는 매년 같은 유형으로 반복되어 사상자가 발생하고 있기에 화재조사결과를 바탕으로 주로 발생되는 형태를 재현실험을 통해 분석하여 동종의 화재를 줄이는데 목적이 있다. 연구방법: 촛불화재 분석을 위해 아크릴 재연실험, 포멕스(FOMEX) 아크릴 재연실험, 일반가연물 재연실험, 촛불의 자연소화 재연실험 등 4가지 방법으로 실시하였다. 연구결과: 주변에 가연물의 접촉이 없으면 지속적인 연소가 이루어지기가 힘들다는 것을 확인하였다. 결론: 촛불화재를 예방하기 위해서는 주변 안전확인이 무엇보다 중요하며 초 말단에 은박지와 같은 불연 재료로 마감 처리하는 등 안전규정을 도입하는 것도 하나의 방법이라고 생각한다.

  • This study aims to examine the risk of electrical fire in places where electric heat wires are used. In general, the use of electric heating wires is becoming more common and prevalent in a bid to prevent increasing damage caused by freezing and bursting in residential water pipes, factory pipes and irrigation pipes in vinyl greenhouse and a variety of heat wire products are available in market with legal safety requirements imposed on them. However, the widespread use of anti-freezing burst heat wire products has caused increasing incidents of fire, which often fail to be incorporated into statistics due to quick onsite extinguishing and insignificant damage although damage is gradually on the rise. Against this backdrop, this study aims to look into the possibility of ignition caused by electric heat wires and the mechanism of how it turns into catching fire through overheat and short circuit tests for anti-freezing burst electrical heat wires (hereinafter called the 'heat wire') and expects to serve as the basis for further observations and analyses on the cause of fire and the process of ignition in a scientific manner.

  • This paper recognizes the risk of ignition of air fryer (machine that can cook fried dishes with hot air without oil) that is far exceeding the sales rate of microwave ovens, which is necessary to modern household kitchen, and identifies fire risk through the operation principle of the process of heat transfer, and the main structure of the machine. The fire test that we conducted is to observe the risk of ignition of the machine due to the damage to the safety system and the possibility of igniting oil paper along with food, to experiment with the possibility of ignition due to blockage of the exhaust due to obstacles, and accumulation of oil stains on the hot wire, and to present the method of fire control and devise countermeasures.

  • The marine industry is rapidly developing as a result of the increase in various needs in the marine environment. In addition, accidents involving ship fires and explosions and the resulting casualties are increasing. Generally, manpower and safety problems exist in fire fighting. A fire fighter in the form of an autonomous surface robot would be ideal for marine fire safety, because it has no manpower and safety problems. Therefore, an autonomous surface robot with the abilities of fire recognition and tracking, nozzle selection, position and attitude control, and fire fighting was developed and is discussed in this paper. The test and evaluation results of this robot showed the possibility of real-size applications and the need for additional studies.

  • This study compared the fire safety standards for windows of Korea, the U.S. and Japan to prevent fire expansion through exterior wall openings, and conducted experiments using PVC and aluminum window frames, which are widely used in Korea.The experiment is KS F 2845 which combines frames of the same thickness and area with single-window form and 1 hour fire resistance glass with 8T thickness. Experiments showed that the PVC window was about 9 minutes and the aluminum window was about 26 minutes. However, in Korea, there are no test standards for windows installed at the opening of the exterior wall. In addition, fire safety standards for windows shall be established along with the designation of fire prevention zones.
