Conservation Status Diagnosis of Mural Painting in Geungnakjeon Hall of Daewonsa Temple, Boseong: Avalokitesvara Bodhisattva Mural and Buddhist Monk Bodhidharma Mural

Abstract

Investigation of conservation status, optical survey, infrared thermography, and ultrasonic examination were performed on Avalokitesvara Bodhisattva mural and Buddhist Monk Bodhidharma mural to determine the conservation status and physical properties. As a result of investigation of conservation status, the types of damage are largely divided into the wall and finishing layer damage, painting layer degradation, damage due to restoration materials, stains and contamination, and biological damage. As a result of the optical survey, drawing, stains, and repainted site were confirmed. Result of the infrared thermography, the delamination of the finishing layer was confirmed, and some locations and shapes of the wooden lath inside the wall were identified. The result of the 3D scanning, the deviation, and the separation of the wall was confirmed. As a result of ultrasonic examination, it was confirmed that the physical properties of the mural were identified and the ultrasonic speed was relatively low due to physical damage such as delamination and exfoliation of the finishing layer and cracking. Ultrasonic speed values were also high in some wall cracks or delamination, and it was confirmed by the infrared thermography results that the wooden lath inside the wall was located in those parts. It was possible to understand that the wooden lath inside the walls affects the ultrasonic speed during the ultrasonic examination. Therefore, management through periodic inspection of the relevant elements is necessary, and a countermeasure for damage that may occur in the future should be prepared along with intensive monitoring of the major damage identified in this diagnosis result.

A Time Series Analysis of Buddhist Painting Using Digital Image Data

“…Scan 등 다양한 과학적 조사 방법들을 병행하여 이루어지 고 있다 (Lee et al, 2018a;Lee et al, 2018b;Lee et al, 2022). 또한 디지털 이미지를 활용하는 연구들이 점차 늘 어나고 있는 추세이며, 최근에는 디지털 이미지의 색상정 보를 이용하여 회화문화유산의 보존상태를 객관적이고 정량적으로 진단 및 평가하는 연구도 이루어졌다 (Kim et al, 2019;National Research Institute of Cultural Heritage and Konkuk University, 2021;2022;Yoo et al, 2022). 3).…”

Manufacturing Technique of the Buddhist Monk Bodhidharma Mural Painting in Geungnakjeon Hall, Daewonsa Temple, Boseong

“…이후 벽체의 재료 특성 에 따른 제작기법 연구들이 수행되었으며(Jeong and Han, 2008;Lee et al, 2012), 벽화 보존을 위한 많은 연구들이 발표되었다(Lee et al, 2015). 지속적으로 사찰벽화의 재 료 특성에 기반하여 제작기법을 규명하고 보존방안을 제 시하는 연구들이 이루어지고 있는 추세이다(Lee et al, 2016;Lee et al, 2021, Lee et al, 2022a.대한 연구가 이루어졌다(Bosung-gun, 2021;Lee et al, 2022b), 더불어 관음보살 벽화의 재료 특성에 기반한 제 작기법에 관한 연구도 보고되었다(Yu et al, 2022).…”
