천연재료를 사용하는 지류유물의 손상은 재질적 특성상 어떤 한 가지 요인에 의한 훼손보다는 물리적, 화학적, 생물학적 복합요인에 의한 손상 가능성이 높다. 문화재보존과학센터는 2009년 12월 현충사 관리소로 부터 이 충무공관련 유물의 상태조사 및 보존처리를 의뢰받아 조사한 결과 위와 같은 다양한 훼손요인을 확인할 수 있었다. 조사결과를 토대로 각 유물의 손상정도를 파악한 후 적절한 보존방안을 수립하고, 2010년부터 약 2년에 걸쳐 보존처리를 실시하였다. 이 충무공 관련 유물 중 고문서, 전적류 등과 같이 형태가 다른 고문헌에 대한 손상유형과 보존처리 내용을 소개함으로서 보존처리방법을 선택하는 하나의 예시를 제안하고자 하였다. 지류유물에 대한 보존처리는 유물의 노화주기를 연장시키고 2차 손상을 방지하지만, 유물의 노화를 완전히 멈추게 하는 과정이 아니므로 유물에 대한 정기적 점검이 필요할 것이다.

In this division, regarding the establishment of operation system of Conservation Science Center, we have tried to find out research trends and advanced operation system of Italian conservation centers, which play an active part in the field of restoration of cultural properties internationally. And the results will be utilized for the establishment of Conservation Science Center. Italy is a country having a long history of restoring cultural properties. In this field, it is largely divided into research & development institutes. And restoration institute and they are operated under system in which research & development institute implement research projects for restoring cultural properties and restoration specialists take receive the results and utilize them. They have different business processing system compared to Conservation Science Center which will implement research-development and restoration(conservation treatment) concurrently. Each institute, carrying out differentiated and specialized research projects per region, maintains smooth cooperative relationship with national institutes, neighboring universities and even afflated schools through horizontal-mutual collaboration joint research, and sharing of equipments, in the field of cooperation between national institutes, cooperation with neighboring universities, and connection to belonging schools. There institutes show us a good example which can be utilized in the future organizational structure of Conservation Science Center. It is expected that their operation system and possessed technologies such as utilization of human resources pool and cooperation with relevant fields can be used usefully in the management and operation of Conservation Science Center.

The Sembilan Archipelago is famous for its great biodiversity, in which the humphead wrasse (Cheilinus undulatus) (locally named Napoleon fish) is the primary commodity (economically important), and currently, the environmental degradation occurs due to anthropogenic activities. This study aimed to examine the eco-environmental parameters and assess their influence on the abundance of humphead wrasse and other coral reef fish compositions in the Sembilan Archipelago. Direct field monitoring was performed using a visual census throughout an approximately one km transect. Coral cover data collection and assessment were also carried out. A coastal water quality index (CWQI) was used to assess the water quality status. Furthermore, statistical-based analyses [hierarchical clustering, Pearson's correlation, principal component analysis (PCA), and canonical correspondence analysis (CCA)] were performed to examine the correlation between eco-environmental parameters. The Napoleon fish was only found at stations 1 and 2, with a density of about 3.8 Ind/ha, aligning with the dominant composition of the family Serranidae (covering more than 15% of the total community) and coinciding with the higher coral mortality and lower reef fish abundance. The coral reef conditions were generally ideal for supporting marine life, with a living coral percentage of about > 50% in all stations. Based on CWQI, the study area is categorized as good and excellent water quality. Of the 60 parameter values examined, the phytoplankton abundance, Napoleon fish, and temperature are highly correlated, with a correlation coefficient value greater than 0.7, and statistically significant (F < 0.05). Although the adaptation of reef fish to water quality parameters varies greatly, the most influential parameters in shaping their composition in the study area are living corals, nitrites, ammonia, larval abundance, and temperature.

In this study, a scientific survey on the material of the mother-of-pearl floor mirror was conducted and conservation treatment processes were introduced. The survey results showed that the mother-of-pearl floor mirror in Daejojeon Hall of Changdeokgung is made of Dalbergia spp., and repair work seems to be done later with shorea spp. FT-IR analysis results showed that the varnishing is similar to the spectrum of lacquer. The metal wheels and metal line decorations set with mother-of-pearl were found to be made of brass based on XRF analysis, and the ingredient ratio showed that these were made in modern times. Foreign materials were stuck on the surface of the mother-of-pearl floor mirror before conservation treatment, which was in a structurally unstable condition owing to some missing submaterials. Conservation treatment was conducted on the damaged area to restore the mirror to its original appearance by using the same species of wood determined from the data obtained through the scientific survey.

There were excavated many relics about 200 pieces including gilt-bronze cap, gilt-bronze shoes, bronze mirror and armor, etc. in Ahndong tumulus, Gildu-ri, Goheung. The National Research Institute of Cultural Heritage was undertaking excavation of major damaged relics that were corroded by several environment and were destroyed by a lump of earth. Shoes are consolidated with soils in order to stop destroy during excavation. And these are relocated in order to treat for conservation. Before treatment, X-ray radiography and CT(Computed Tomography) are used in order to examine the original surface and the shape of shoes. As a result, we confirm the condition of shoes. If soils are removed, gilt-bronze shoes are crumbling into little pieces because gilt-bronze shoes are damaged by corrosion and deformation. So, shoes are consolidating with inner soils and are removing outer soils. Throughout conservation treatment, shoes recovered original form and inner soils are consolidated in order to keep the shape of shoes.

석조문화재는 조성된 직후부터 복합적 훼손요인에 의해 손상되거나 본래의 역사적 진정성을 잃어버린 채 현재에 이르게 된다. 원형보존과 진정성을 회복시키기 위한 다양한 인위적 개입을 원주 법천사지 지광국사탑 보존처리 사례를 중심으로 설명하였다. 지광국사탑의 보존처리는 해당 문화재의 연구와 보호에 기여하는 모든 과학적 기술적 수단을 확보한 후 진행하였으며, 지광국사탑의 미학적, 역사적 가치를 보존하고 원 재료와 원형에 대한 이해를 바탕으로 추진하였기 때문에 과도한 복원은 지양하였으며 원형보존과 진정성을 회복하는데 기여한 것으로 판단된다.

울산 반구대 암각화는 1965년 축조된 사연댐으로 인해 매년 4~8개월간 침수와 노출을 반복하면서 훼손이 진행되고 있다. 이에 직접적 보존처리에 앞서 현장적용실험을 위한 사이트를 선정하여 각각의 손상을 제어할 수 있는 보존처리를 실시하였다. 모든 처리에는 비파괴조사를 실시하여 처리 전 후를 정량적으로 평가하였으며 모니터링을 위한 기초자료를 구축하였다. 실험 결과 처리재료보다 처리기술과 적용방법에 따라 처리효과에서 큰 차이를 보였다. 특히 에틸실리케이트 수지를 이용한 강화처리는 처리방법에 따라 초음파 속도 및 에코팁 경도상승이 확연히 구분된 결과를 도출하였다.
