The Gilt-bronze seated Buddha at Sinamsa temple in Dangin has an uneven in the shape the gilt, poor gloss and cracks were damaged. Such damage to the gold-gilding layer may degrade the corrosion resistance of the Buddha statue, thereby promoting corrosion of the metal compound. The Buddha statue was a restoration in the 1980s, and it was highly likely that modern materials such as cashew were used as adhesive materials for gold-gilding. In the study, a conservation management plan was proposed by comprehensively examining the material characteristics of the gold-gilding layer and adhesives. As the composition analysis, all gold-gilding layers show high Au content, so it seems that pure gold was used, and copper and tin were detected as the main alloying materials for the base metal, corresponding to a bronze. Various analyses of the gilt adhesive material, it was found that gilt was recovered using cashew. The cashew has a weaker adhesion than the lacquer, so the blistering of gold powder and gilt proceeds faster, and can cause various damages such as metal corrosion and whitening. In order to stably preserve the Gilt-bronze seated Buddha at Sinamsa temple and restore the authenticity, it is necessary to remove the cashew covering layer and perform lacquer gold-gilding.

The tomb complex of the royal family from the period of the Ungjin Baekje Kingdom (475 to 538 AD) in Gongju, Korea, contains the tomb of King Muryeong and other royal tombs. After the excavation of the tomb of King Muryeong in 1971, these tombs were opened up to the public, without the establishment of systems for their safety, conservation and management. The tombs have consequently experienced rapid environmental changes and suffered various damages. In this study, specific vulnerable parts inside the tombs were selected for deviation analysis using 3D scanning, and 3D image models were constructed on this basis. Progressive displacement was identified in tomb No. 5, and basic data for future investigations was acquired from tomb No. 6 and the tomb of King Muryeong. In the deviation analysis for the southern plastered wall of tomb No. 5, the damage was not found to exceed the ranges of ±18 mm and ±2 mm. However, the lintel stone was found to be sagging by 0.32 mm on average, and the distance between the walls to have increased by 0.36 mm on average. Direct water seepage occurring in tomb No. 5 is considered to be increasing the damage within the tomb, such as the dropping and sagging of the lintel. The 3D image models constructed in this study will play an important role as baseline data for future research, and can be used to discuss a secure conservation scheme for the tombs through cross-validation with precise measurement monitoring.
