Abstract

Biological damages of wooden cultural properties are closely related to the preservation of the environment; these damages can be accelerated because of rapid climate change. Therefore, to preserve cultural properties, it is important to understand environmental characteristics. This study aims to investigate the status of termite damage and the characteristics of major environmental factors such as micro-meteorology, meso-meteorology, and local-meteorology of the Josadang shrine in the Seonamsa temple at Suncheon. Damage was confirmed by visual observation and the response of the termite detection dog at the north-west corner. Also another damage was observed by the termite detection dog at the north-east corner. These pillars had lower surface temperature and higher moisture content compared with the pillars in the front. The mean temperature of the entire time was similar for the meteorologies; however, the relative humidity differed. High relative humidity, greater than 70%, was observed frequently. In particular, it was determined that the termite activity days were the most inside the Josadang shrine. The statistical analysis confirmed that there was a difference between the meteorology events through the F ratio. In addition, the difference of environmental factors with relative humidity and temperature was identified more great difference in relative humidity through the t-statistics of temperature and relative humidity. And then relative humidity was confirmed most great in the difference of meso-meteorology and local-meteorology.

목조문화재의 생물피해는 보존환경과 밀접한 관계가 있고, 급속한 기후변화로 인해 피해가 가속화될 수 있으므로 문화재 보존을 위해서는 환경 특성을 파악하는 것이 중요하다. 따라서 본 연구에서는 순천 선암사의 조사당을 대상으로 흰개미 피해 현황과 미기상, 중기상, 국지기상의 주요 환경인자 특성을 관찰하였다. 그 결과, 조사당 북서쪽 기둥에서 뚜렷한 육안피해와 흰개미 탐지견 반응이 있었고, 북동쪽 기둥에서 흰개미 탐지반응이 추가되었다. 이 기둥들은 전면에 위치한 기둥보다 표면온도가 낮고 표면 수분량과 함수율이 높은 특징이 있었다. 각 기상의 전체 시간 평균온도는 비슷하였으나 상대습도는 차이가 있었고, 미기상은 70% 이상의 높은 상대습도가 빈번히 나타났다. 특히 조사당 내부에서 흰개미 활동 일수가 가장 많았던 것으로 산출되었다. 통계 분석 결과에서는 F 비를 통해 세 기상 간 차이가 있음을 확인하였다. 또한 온도와 상대습도의 t 통계량을 통해 환경인자 간의 차이는 온도보다 습도가 더 크고, 중기상과 국지기상에서는 상대습도 차이가 더 큰 것이 확인되었다.
