이 연구에서는 하이퍼스펙트럴 이미지를 활용하여 석조문화재의 훼손상태 모니터링에 대한 활용성을 검토하였다. 이를 위해 하이퍼스펙트럴 데이터의 보정방법, 영상분류 및 정규화 식생지수 산출방법을 석조문화재에 적용하였다. 이 결과 각 물질의 분광정보를 기반으로 한 객관적인 훼손지도 작성, 정밀도 높은 훼손율의 산출 및 식생들의 활력도 모델작성 등 다양한 분석이 가능하였다. 따라서 하이퍼스펙트럴 이미지 분석을 활용하여 석조문화재를 모니터링 한다면 효율적으로 훼손상태 변화를 파악할 수 있을 것이다.

Woolen tapestry curtains possessed by the Seoul Museum of Craft Art were used to hung on the wall or used for carpets in the winter season in the late Joseon dynasty. Since similar artifacts were only used for the curtain as functional aspects, woolen tapestry curtains were a rare case. In this study, scientific analysis on the accessory ornament of woolen tapestry curtains such as components of metal accessories and frame bar were conducted with the microscope, p-XRF, and SEM. Result of frame bar pigments, organic pigments such as ink stick were likely been used in woolen tapestry curtain 1. In woolen tapestry 2, lead red (Minium) was used in the frame bar. The result of metal parts, copper, and zinc were analyzed by p-XRF. This suggests that metal accessories were crafted using brass. Frame bar of woolen tapestry curtain 2 was made of soft pine (Pinus spp.) analyzed with the scanning electron microscope. Artifacts like woolen tapestry curtains are rare in Korea and scientific analysis databases were scarce, so it is important to construct components analysis data of woolen tapestry curtains. It is expected that additional scientific analysis and interpretation on the artifact's crafting technique can be merged with the analytical data gathered in this study to be utilized on the conservation and restoration of not only woolen curtains but curtain artifacts of the late Joseon dynasty in general.

We have evaluated the antifungal activities of oak vinegar to develop a natural biocide for organic cultural heritage. Fungi used in this study were screened from the cultural heritages, Kyujanggak and JanggyeongPanjeon and tested on organic substrates-degrading ability. In the results, 7 species of fungi have produced the extracellular enzymes to degrade CMC, xylan, lignin. Thus, we have used these seven species fungi to investigate the antifungal activity of oak vinegar in this study. In the result, the antifungal activity of oak vinegar indicated positive potencial. Especially, methylene chloride and ethylacetate fractions of the oak vinegar had high activities at the concentration of 5.0mg/disc. In these fractions, many different kinds of compounds such as phenolic and furfural, etc. were analyzed by GC-MS. The experiments indicated that the development of a biocide using natural extracts can have a potential to conserve of organic cultural heritages.

The Choijin Lama Temple is a representative example of 19th- to 20th-century architecture. The temple has been damaged by various development pressures and the effect of a harsh continental climate. This study digitalized the entire temple site using three-dimensional scanning to establish the basic data of conservational management and monitoring for spatial changes. A terrestrial laser scanning model of the temple was completed, which showed low registering error vectors (3.73 mm average) and dense point distances. Unmanned aerial vehicle (UAV) photogrammetry was also applied to verify its applicability to the spatial and environmental monitoring of the temple. The results showed that the overall point density of the UAV photogrammetry model is similar within a 10 mm resolution. The relatively low RMSE of UAV photogrammetry from the ground to the uppermost roof indicates the high applicability of integrating it with the terrestrial laser scanning model. The digital documentation of the Choijin Lama Temple is expected to have a great ripple effect on the documentation, conservation, and utilization of Mongolian cultural heritage sites.

본 연구는 초등 교육에서 문화유산이 학교에서 어떻게 교육적으로 이용되고 있는지, 그리고 교사는 문화유산 교육을 어떻게 실행하고 있는지를 살펴보고 이에 의거하여 문화유산 교육의 방향을 제언하는 데 목적을 두었다. 이를 위해 초등학교 5개 교과서를 살펴보고 문화유산 교육 경험이 있는 10명의 교사를 대상으로 설문하여 그 결과를 분석하였다. 분석 결과를 토대로 다음의 다섯 가지를 제언하였다. 첫째, 문화유산 교육의 목표를 시민성 함양으로 확대해야 한다. 둘째, 문화유산 교육에서 무엇을 교육 내용에 포함할 것인가에 대한 논의와 학생 환경, 지역 사회 환경, 교과 내용 등과 연계하여 체계적인 내용 구성이 필요하다. 셋째, 문화유산 교육은 문화유산이 현재 세대에서 미래 세대로 이어질 수 있게 지속 가능 발전 개념과 연계되어야 한다. 문화유산은 국가의 경계를 넘어선 인류의 보편적 가치, 지역별 정체성, 문명 간 대화와 이해, 창의성의 원천 등 특성을 갖고 있어서 지속 가능 발전의 토대가 된다. 넷째, 학교에서 문화유산 교육의 효과적 실행을 위해서는 단계별 교사 연수 프로그램 개발이 필요하다. 학교에서 문화유산 교육의 성패는 교사 연수에 달려 있다. 다섯째, 문화유산 교육을 교육 과정에 통합하는 정도를 강화해야 한다. 이를 통해 학습자가 문화유산에 대한 지식과 비판적 사고력을 함양하여 향유하고 보호하고 지속 가능 발전 사회와 연결해 나갈 수 있도록 교육해야 한다.

Korean wooden cultural heritages are treated by flame retardants to protect fire hazards. Two types of flame retardants are used to treat wooden cultural heritage. These flame retardants cause some problems such as surface whitening, discoloration, and cracks due to the chemical reaction caused by Korean traditional wood painting (Dancheong), flame retardant and wood humidity. The Korean government is trying to cut down on the amount of flame retardants for the wooden cultural heritage because of these problems. This study was carried out to find the cause of whitening by flame retardants treatment. The reaction between pigment and flame retardant chemicals was analyzed by infrared spectroscopy.

The Wooden Seated Amitabha Buddha Triad and Altarpiece have not been the subjects of definitive species identification and scientific analysis. In this study, visual investigation, portable X-ray fluorescence (p-XRF), species identification, and lacquer layer observations were carried out to determine the original materials and conservation status. Cracks, exfoliation and discoloration were detected during the visual investigation. The p-XRF data indicated that chrome oxide green, malachite, gold, cadmium red, cinnabar, minium, hematite, lead white, ink stick (Carbon), and copper were used for pigments and the coronet accessory. Tilia spp., Abies spp., and Pinus spp. were identified from both the Buddha Triad and Altarpiece. Finally, lacquer layer analyses of the base layer, lacquer layer, orange pigment layer, and gold leaf layer observed modern synthetic pigments likely used in previous conservation. As the Korean Cultural Heritage Charter and the International Charter for the Conservation and Restoration of Monuments and Sites clearly state that objects of cultural heritage must be conserved using their original materials, future conservation of these objects should utilize the data obtained in this study to employ traditional materials. Furthermore, a deterioration map diagnosis can be applied together with the obtained analysis data to understand the conservation status of and inform an appropriate and authentic conservation treatment for the Buddha Triad and Altarpiece.
