목조건축문화재의 생물피해 영향을 미치는 야외 부유곰팡이의 연중 변화와 일간 변화를 파악하기 위해서는 포집주기와 측정시간대의 충분한 반영이 필요하다. 본 연구는 2018년 8월부터 2019년 7월까지 1년간 국립문화재연구소 보존과학센터 옥상에서 에어샘플러와 Potato dextrose agar 배지를 이용하여 포집주기는 24절기, 포집시간대는 14시(낮)와 23시(밤)에 포집하였고, 기상요소를 1시간 단위로 수집하였으며, 부유곰팡이의 농도 조사 및 기상요소와의 상관성 분석을 진행하였다. 그 결과, 부유곰팡이 농도는 11월, 가을, 밤에 가장 높았고, 가을, 여름, 겨울, 봄 순으로 높았으며, 강우, 태풍, 황사/미세먼지에 따라 부유곰팡이 농도, 종류, 우점은 달랐다. 부유곰팡이 농도는 강수량, 강수일수, 상대습도와 강한 양의 선형 상관성이 나타났다. 부유곰팡이 농도는 영양원에 있어서는 죽은 식물체의 증가 시기, 기상요소에 있어서는 강우를 포함한 높은 상대습도 조건과 관련이 깊었다.

ABSTRACT
To identify daily and annual changes in outdoor airborne fungi, it is necessary to shorten the collection cycle and increase the number of measurements. In this study, measurements were performed by employing an air sampler and potato dextrose agar media on the rooftop of National Research Institute of Cultural Heritage during a period of one year (August 2018 to July 2019). The collection cycle spanned the twenty-four seasonal divisions and the collection time was 2 p.m. and 11 p.m.. Meteorological elements were collected at intervals of one hour. Furthermore, the concentration of airborne fungi was monitored and correlation analysis with meteorological elements was subsequently conducted. Obtained results indicate that the concentration of airborne fungi is found to be highest in November, autumn, night, followed by autumn, summer, winter, and spring. The concentration, type, and dominant species of airborne fungi can vary depending on factors such as rainfall, typhoons, and yellow dust (fine dust). The concentration of airborne fungi indicates a strong positive linear relationship between precipitation, number of precipitation days, and relative humidity. The concentration of airborne fungi was related to the period of increase of dead plants in terms of nutrition source, and to the high relative humidity conditions including rainfall in terms of meteorological elements.
