This study was conducted to examine the functionality of the fire retardant treated wood. The hygroscopic property, leaching resistance, metal corrosive efficacy and gas toxicity of retardant treated wood were analyzed. Sodium silicate was penetrated to the wood for making fire retardant treated wood. The subsequent treatment agents such as boric acid, ammonium borate, di-ammonium phosphate were treated after sodium silicate treatment due to fixation. As results for the test, the leaching resist was improved by subsequent treatment. The fire retardant combination such as sodium silicate, boric acid and di-ammonium phosphate showed high hygroscopic property, metal corrosive efficacy. The gas toxicity was also satisfied KS standard.

국내 저층 공동주택 화재시의 화재 전파 경로와 상층으로의 화재 전파를 살펴보기 위하여 4층 공동 주택을 대상으로 실물화재 실험을 수행하였다. 화재는 3층 주택에서 발화하는 것으로 하였고, 초기 화원은 주방에서 과열된 식용유에 발화되어 발생하는 것으로 하였다. 주택 내부 가연물은 일반 가정의 필수 가연물을 모두 포함 하였다. 내부 화재 성상을 확인하기 위하여 가시화, 주요부의 온도측정, 산소농도 측정을 수행하였다. 실험 결과 초기 화원의 발화 시간, 화재 층 내부 각 구획으로의 전파시간, 전역화재 발생시간을 파악하였으며, 상층으로의 연소확대 경로를 파악하였다.

Conventional fire detection systems use physical sensors to detect fire. Chemical properties of particles in the air are acquired by sensors and are used by conventional fire detection systems to raise an alarm. However, this can also cause false alarms; for example, a person smoking in a room may trigger a typical fire alarm system. In order to manage false alarms of conventional fire detection systems, a computer vision-based fire detection algorithm is proposed in this paper. The proposed fire detection algorithm consists of two main parts: fire color modeling and motion detection. The algorithm can be used in parallel with conventional fire detection systems to reduce false alarms. It can also be deployed as a stand-alone system to detect fire by using video frames acquired through a video acquisition device. A novel fire color model is developed in CIE $L^*a^*b^*$ color space to identify fire pixels. The proposed fire color model is tested with ten diverse video sequences including different types of fire. The experimental results are quite encouraging in terms of correctly classifying fire pixels according to color information only. The overall fire detection system's performance is tested over a benchmark fire video database, and its performance is compared with the state-of-the-art fire detection method.

Objectives : Saam acupuncture has evident principles of prescription based on acupuncture tonification and purgation of Nan-gyeong but many prescriptions of Saam acupuncture are not typical patterns. This paper studies principles of prescriptions of the king fire and the premier fire. Methods : Through investigation of many medical documents concerning king fire and the premier fire, the author explained of physiological and pathological principle of king and the premier fire, also explained of interacting mechanism through five element. And The theoretical authorities of analysis are Nan-gyeong, works of Joo dan-gye and Li dong-won. Results & Conclusion : 1. The sufficiency and the control of the water is the key to treat the disease by fire. Considering the attack and the treatment of disease, heart and liver give rise to fire in its early stage and kidney and lung are the key to treatment. 2. Consequently the pathology of the disease from fire is corresponding to the theory- Yang Sufficient, Yin Deficient- of Joo dan-gye. It seems that the theory of Joo dan-gye influenced on the medical theory of Saam Acupuncture. 3. On that account I believe that the study of medical theories of the Geum and Won Dynasty that various medical theories had appeared is very available for Saam Acupuncture. At present global warming is accelerating because environmental pollution has been increasing. Therefore the damage of fire to human body will be more and more severe and extensive. Because in the future medical plants will not be free from environmental pollution, acupuncture will be very confidential treatment.

According to the fire statistics of the Ministry of Home Affairs, the fire ratio in factories, work places and warehouses shows 21.5% among total fire of buildings except the fire on cars or other fires. Especially, the buildings like factories and warehouses, which have a lot of ignitable sources and thus always have a strong possibility of fire, are needed to have well planned strategy in terms of life safety and property protection. In this respect, the present paper analyses the existing fire cases in factories, finds out the fire properties of factory buildings, and evaluates the codes concerning fire resistance and fire severity.
