부안 개암사 대웅전 포벽화 보존상태 진단 및 평가 = Study on Diagnosis and Evaluation of the Conservation Status of Bracket Mural Painting in Daeungjeon Hall of Gaeamsa Temple, Buan

다국어 초록 (Multilingual Abstract)

In this study, the conservation status of the bracket mural paintings was evaluated by conducting a conservation environment survey, conservation status diagnosis by visual, optical investigation, and infrared thermal imaging, and diagnosing the physical properties through ultrasonic detection. The range of temperature and humidity fluctuations inside Daeungjeon Hall tended to be similar, and the difference in relative humidity was confirmed according to the orientation. The external temperature and humidity fluctuations range were larger on the south side than on the north side. In particular, it was confirmed that the relative humidity was affected by the increase in precipitation due to the rainy season. As a result of the conservation status diagnosis, it is confirmed that the main damage patterns are wall cracks, delamination and exfoliation of the finishing layer, delamination and exfoliation of the painting layer, and contamination. Contamination such as dust accumulation or stains on the surface occurred, and damage due to delamination or exfoliation of the painting layer was also confirmed. Through infrared thermal imaging and optical investigation, the range of wall delamination and contamination damage could be identified. As a result of evaluating the degree of damage by synthesizing this, the characteristics of the damage were confirmed according to the orientation and location of the bracket mural paintings in the building. On the west side and the north side, the damage to the wall layer was intensified, and the damage to the painting layer was intensified on the south side. Through ultrasonic detection, the relative properties of each bracket mural painting could be compared, and a tendency similar to the degree of damage to the wall layer was confirmed. The evaluation of the conservation status of the bracket mural paintings on the Buddhist temple should be conducted in connection with various scientific investigation methods, and it is necessary to comprehensively interpret and judge the results. It is believed that the results of this study can be used as effective data for diagnosing the conservation status of bracket mural paintings on buddhist temples in the future.
