This paper introduces a novel sensor network protocol, R-WSLP(Realtime Wireless Sensor Line Protocol), which has extremely low latency characteristic in large-scale WSN. R-WSLP is proposed to implement realtime forest fire monitoring system. We propose Distributed TDMA method for the multiple channel access and Time Synchronized Forwarding Mechanism instead of routing technique to achieve low latency network. Also, R-WSLP provides extremely low power operation which we accomplished by reducing idle listening. In our experimentation, we get successful results at the forest fire monitoring system with our protocol.

본 연구에서는 역사기록서 분석을 통해 조선왕조시대 산불방지정책을 분석하였다. 조선왕조시대 산불방지정책은 크게 예방분야와 민생안정에 관한 정책으로 구분할 수 있었고 산불예방분야에서는 산불발생가능지역과 산불보호대상지역으로 구분하여 예방정책을 시행하였다. 산불발생가능지역으로는 화전경작 산림지역, 강무장 등 사냥터, 봉수대 주변 산림지역, 병해충 구제를 위한 입화 가능지역이며 왕실묘 주변, 사고(史庫), 소나무 육림을 위한 산림인 금산 또는 봉산, 도성 숲은 산불보호대상지역에 포함되어 산불방지정책을 시행하였다. 민생안정에 관한 정책에서는 산불피해지역 백성을 위로하고 산불피해지 복구를 위해 어사를 파견하여 구휼토록 정책을 펼쳤다. 특히, 산불예방정책 시행을 위반하여 산불을 발생시킨 죄에 대해서는 엄하게 책임을 물어 귀양에서부터 사형에 이르는 처벌을 내렸다. 결론적으로 조선왕조시대에도 산불의 심각성으로 인해 조정 및 지방관서 등에서 여러 방지정책들이 시행되었다는 것을 알 수 있다.

we studied and analyzed a tree mortality of 7 species(Pinus koraiensis etc) in surface forest fire area. In this results, the order of tree mortality was Cryptomeria japonica>Pinus koraiensis>Pinus densiflora>Pinus thunbergii>Larix leptolepis>Pinus rigida>Quercus. More damaged crown was higher tree mortality and more d.b.h was less tree mortality. Especially, oak trees in which a damage rate of crown was less 30% almost survived.

Recently, unusual change of weather occurred in world wide region causes localized heavy rainfall and consequently disasters like landslide and debris flow in steep slope area. And the main factors of these disasters are rainfall and forest fire. To verify the existing landslide prediction and warning system, information about landslide and rainfall were collected for a data base system and analysed.

Because forest fire can give a serious damage to overhead conductors, the thorough understanding about aging behavior of burned conductor is very important in maintaining the transmission line safely. Therefore, a systematic investigation was carried out by heating method. As the heating temperature increases, drastic change of tensile strength of Al wire due to the softening of Al wire occurred. When Al wire is exposed to the flame(about $800\;^{\circ}C$) during only 13 seconds, the remained tensile strength of Al wire showed under 90 %. The detailed results will be given in the text.

Because forest fire can give a serious damage to overhead conductors, the thorough understanding about sag behavior of burned conductor is very important in maintaining the transmission line safely. Therefore, a systematic investigation was carried out by heating method. As the heating temperature increases, drastic change of tensile strength of Al wire due to the softening of Al wire occurred. When Al wire is exposed to the flame(about $800^{\circ}C$) during only 13 seconds, the remained tensile strength of Al wire showed under 90%. and then sag of overhead conductor become deteriorated. The detailed results will be given in the text.

AVHRR(Advanced Very High Resolution Radiometer) on NOAA satellite provides data in five spectral, one in visible range, one in near infrared and three in thermal range. In this paper, application of NOAA/AVHRR data is studied for environment monitoring such as cloud top temperature, surface temperature, albedo, sea surface temperature, vegetation index, forest fire, flood, snow cover and so on. The analyses for cloud top temperature, surface temperature, albedo, sea surface temperature, vegetation index and forest fire showed reasonable agreement. But monitoring for flood and snow cover was uneasy due to the limitations such as cloud contamination, low spatial resolution. So this research had only simple purpose to identify well-defined waterbody for dynamic monitoring of flood. Based on development of these basic algorithms, we have a plan to further reseach for environment monitoring using AVHRR data.

After destruction of the Naksansa which was due to Yangyang forest fire, this the fundamental research about the disaster prevention countermeasures of tradition buddhist temple cultural treasure was performed. The present condition of tradition buddhist temple and related laws were investigated and the present damage condition of the Naksansa was surveyed. Also, the fire damage cases of tradition buddhist temple and the fire laws and regulations were investigated, and the survey about disaster prevention countermeasures was carried out. This research drew up the basic material about the disaster prevention countermeasures of traditional buddhist temple.

The wildland fire intensity and scale are getting bigger owing to climate change in the world. In the case of domestic, the forest is distributed over approximately 63.7 % of country and the main facilities like a industrial facility or gas facility abuts onto it. Therefore there is potential that the wildland fire is developed to a large-scale disaster. In this study, the effect distances of the radiant heat flux from the crown fire are analysed according to the change of wind velocity. The safety criteria concerning the radiant heat flux to influence on the surrounding were researched to analyse the effect distances. The criteria of radiant heat flux were chosen $5kW/m^2$, $12.5kW/m^2$, $37.5kW/m^2$. WFDS, which is an extension of NIST's Fire Dynamics Simulator, was used to consequence analysis of the forest fire. In order to apply the analysis conditions, it is researched the forest conditions that is generally distributed in domestic region. As the result, the maximum effect distances by radiant heat were showed at the horizontal and vertical direction. When the wind velocity varied from 0 to 10 m/s, the maximum effect distance increased as the wind velocity increases. Interesting point is that the maximum effect distance were shown at the wind velocity of 8 m/s. The maximum effect distance was decreased according as the fuel moisture of trees increase. This study can contribute to analyse quantitative risk about the damage effect of the surrounding facilities caused by wildland fire.
