본 연구에서는 양양산불에 의한 낙산사의 소실이후 전통사찰 문화재의 방재대책에 대한 연구를 실시하였다. 전통사찰의 현황과 관련 법규를 검토하였고, 양양산불의 발생에 따른 화재특성과 낙산사의 피해현황에 대해 정리하였다. 또한 낙산사 소실로 본 전통사찰의 화재피해사례와 관련 소방법규를 검토하여 문제점을 제시하였고, 낙산사의 소실에 따른 방재대책에 대해 설문조사결과를 제시하여 향후 전통사찰문화재에 대한 화재예방안전대책을 제시하고자 한다.

Aphanisticus congener is a newly recorded buprestid (Coleoptera) insect pest of turfgrass in Korea. This buprestid pest was initially found from turfgrass conservation site in a greenhouse in Jinju, Gyeongnam province, Korea in July, 2014. The Aphanisticus in the family Buprestidae is a leaf miner. A. congener is the close species of A. aeneus which was firstly reported as sugarcane leaf sucker in India. A. congener was active from early July to late August in the greenhouse. Damage by the insect led to drying out and browning of turfgrass leaf because larva fed on cell sap of leaves and adult fed on leaf surface. A. congener damaged Zoysia japonica, Z. sinica, Conodon dactylon, and Poa pratensis when adults were artificially released into potted turfgrasses in the laboratory. In green house, A. congener damaged Z. japonica, Z. macrostachya, Z. matrella, Z. sinica, Conodon dactylon, and hybrid zoysiagrass. However, no damage symptoms were observed from the same turfgrass accessions in the nearby field of the greenhouse. Thus, the new coleopteran pest may be a warm-adapted pest for turfgrass, damaging turfgrass leaf only in warmer conditions.

Recently, it has been important not only to evaluate environmental effects but also to assess cumulative and comprehensive effects by the development projects. This paper concentrates on temporal and spatial cumulative impacts on Suji district in Yongin, Gyunggi-do. This paper adopted two methods to assess the cumulative impacts. First, it assesses the temporal change of forest patch size and land cover according to the patch size. Second, it compares housing development zones with the neighborhood. The result of the research appears that the damage is very serious, especially in small forest. The Forest area is changed to farm land, most of them become to built-up area later. In addition, it is assessed that the secondary housing development projects did more harm than the initial one. By assessing the cumulative impacts on Suji district, this research suggests to minimize two kinds of solutions : comprehensive environmental assessments in regional unit and regulation on total forest quantity.

We investigated the enect of $O_3$ on the photosynthetic characteristics of tree of heaven (Ailanthus altissima) that is naturalized plant and used as restoration plant for contaminated area. Two-year-old seedlings were planted to pots and transferred into closed $O_3$ chamber. Photosynthetic pigments contents and photosynthetic characteristics were measured every three weeks under 100 pub $O_3$ fumigation. There was no visible foliar injury by $O_3$ exposure and contents of photosynthetic pigments did not show significant differences between control and $O_3$-treated seedlings. Also there were no significant differences in stomatal conductance, and water use efficiency. But photosynthetic rate and apparent quantum yield (AQY) of $O_3$ treated seedlings were reduced after nine weeks of ozone fumigation. In addition, the reduction of carboxylation efficiency and photorespiration were observed in the leave of $O_3$ treated seedlings after six weeks. In accordance with our result, carbon fixation system of A. altissima was most sensitive to $O_3$ stress to evaluate physiological damage induced by $O_3$.

수관화는 대형산불의 주된 확산유형으로 빠른 확산속도와 높은 산불강도의 특성을 보이며 많은 피해를 입힌다. 이 연구에서는 수관화 피해를 사전에 예측하기 위해서 수관전소 피해를 입은 지역의 지형 임상 기상 특성을 분석하여 수관화확산확률식을 개발하였다. 영덕 울진 고령 예천에서 일어난 4개의 산불피해지를 대상으로 하였으며, 총 18개의 공간 변수를 구축한 뒤 기타연소지에 대한 수관전소지의 비를 이용하여 각 변수별 구간 가중치를 구하고 로지스틱 회귀모형을 이용하여 변수와의 상관계수를 산출하였다. 그 결과, 수관화확산확률은 임상이 침엽수림일 때, 250m 이상에서 고도가 높아질수록, 기복이 심할수록, 사면향은 남서 또는 남동사면일 경우, 능선일수록, 일사량이 많아질수록 높게 나타났다. 고도와 경사가 낮은 곳에서는 교란현상이 많이 나타나 일정한 패턴을 보이지 않았다. 이 확률식을 통해 수관화 위험지를 사전에 분석할 수 있고, 산불방지 숲가꾸기 지역 선정 및 진화 우선 지역 선정 등에 효과적으로 활용할 수 있을 것이다.

Forest Fire can cause a serious damage to overhead conductors. Therefore, the detailed investigation for the changes of mechanical and electrical properties of damaged conductors should be carried out to understand the effect of forest fires on conductors. This is very much important to maintain transmission line safely. Oxidation of overhead conductor was increased with temperature and time(maximum time : 30min). Conductivity of Al conductor was decreased by Agents. The detailed will be given in the text.
