Fire Science and Engineering, volume 19, issue 4, 2005, Pages 1~6
To control forest fire effectively, it is necessary to understand forest fire behavior and relevance to forest fire environmental factors. In this paper, the behavior characteristics of the 2005 Yangyang forest fire were analyzed into the spread patterns and severity grades. The spread processes of the forest fire could be divided into two steps. At the first step, the fire ran fast to the east due to the strong west wind and then spreaded out in irregular direction. The maximum spread rate of the fire was 1.21km/hr and the mean was 0.65 km/hr. The result of the fire severity classification indicated that about
(1,110ha) of the whole study site was extremely burned and the remaining
were damaged slightly and moderately respectively.

A water mist system was considered as a possible alternative to a gaseous suppression system that can not prevent re-ignition after fire extinguishment for a power transformer room. This study deals with the fire suppression capability of the water mist systems. High-and low-pressure water mist systems were examined to compare efficiency of both systems. The power transformer examined in this study occupied about
transformer room. Full-scale suppression tests were performed for six different fire scenarios: two spray fires, three pool fires and one cascade fire. The fire suppression test results demonstrated that the high-pressure system was superior to the low-pressure system, especially considering oxygen depletion and the ambient temperature distribution.

Fire Science and Engineering, volume 19, issue 4, 2005, Pages 37~41
The present study describes the cooling performance of two kinds of water mist systems used in fire extinguishment. The cooling is necessary for the prevention of an auto re-ignition of the power transformer. A heat source for such the re-ignition is the accumulated thermal energy in the dielectric oil from the transformer core. Because of the weight of the real core, reduced-scale experiments are carried out. A similarity analysis Is also performed to determine the discharge time of the water mist systems from the experimental results. The discharge time to prevent the re-ignition in the real-scale transformer is estimated about 12 hour from the similarity analysis of the reduced-scale experiments.

Fire Science and Engineering, volume 19, issue 4, 2005, Pages 80~86
Fire fighting officials perform their works in the field and in most cases, undergo circular appointments for their service period. If they don't gain experience in field works, they have difficulty in performing faithful planning or administrative works. So they surely have to gain experiences in field works. Like this, fire fighting officials' works comprise a lot of fields, comparing with other job workers. So they need a strict body condition. The aim of this inquiry is to scrutinize body standards and important roles concretely which are necessary to fire fighting officials, to analyze written examination, physical test, physical strength test, and interview examination, and to establish the proposal which is necessary to improvement.
