The purpose of this study is to scientifically analyze physicochemical characteristics of the roof tiles used for palaces in the Joseon Dynasty which stored in Changdeokgung material storage and Seooreung Jaesil and the modern handmade ones which made by N company to understand the differences between their manufacturing techniques. Through chromaticity, cross-sectional observation, component analysis, and crystal structure analysis, it was possible to confirm the physicochemical properties and fired properties of the roof tile. Roof tiles from the Joseon Dynasty have a wider colorimetric range and higher apparent porosity and water absorption, on average, than the modern roof tiles. The cross section of the Joseon Dynasty roof tiles shows that most clay minerals have not been vitrified, remaining in the form of atypical particles, while the modern roof tiles have denser clay materials. X-ray diffraction analysis identified low-temperature minerals such as micas in Joseon roof tiles but no peak of these minerals was observed in the modern roof tiles, implying that the modern ones are fired at higher temperature than the Joseon ones. Therefore, the modern roof tiles are fired at higher temperature and have higher density than the Joseon ones due to the use of pugmills. The general content of main ingredients was similar between the two. Additionally, the principal component analysis of trace elements in the Joseon roof tiles showed that most samples were from similar areas. It seems that the Joseon roof tiles were manufactured using soils supplied from a specific region at the same timeframe and their consistency in the content of principal components implies that they also have similar mix proportions of clay.

This study demonstrates the application of hyperspectral analysis as a pigment identification method for modern and contemporary Dancheong, the polychrome surface on traditional Korean wooden buildings. In particular, green pigments are the focus of this study. Green pigments in modern and contemporary Dancheong have the largest variation of materials and show a noticeable timeline. Thus, they are most suitable for estimating the manufacture or restoration period of Dancheong. Hyperspectral analysis is a noncontact, long-distance measurement technique that has advantages in the field of Dancheong analysis. It is capable of identifying both organic and inorganic pigments, unlike existing analysis methods. For this experiment, green and other pigments used during the modern and contemporary era were selected and made into painted samples under various mixing conditions that reflect their actual uses. Through hyperspectral analysis, their reflectance characteristics were observed, which enables the derivation of four main features that can distinguish the type of pigments used for color mixture. Based on these, a pigment identification system was designed in the form of a flowchart, and its utility was confirmed through site application. Despite some limitations at this stage, the technique can be complemented by considering proper measurement methods or the continuous accumulation of samples and data. If a database on various materials, mixing ratios, painting techniques, and other external interference factors is developed in future research, it would provide the foundation for a faster and safer analysis environment of Dancheong sites.

This study aims to develop a cultural heritage curriculum for climate change and present educational directions for cultural heritage and climate change impact in the future. In this study, the role and necessity of cultural heritage education for climate change were first discussed based on previous studies on climate change and cultural heritage. Next, the current status analysis of educational cases related to climate change and cultural heritage was conducted based on educational manuals, curriculum, and heritage competency systems associated with climate change. Finally, we propose a plan to develop a curriculum to cope with climate change and cultural heritage for graduate students in higher education institutions based on the four components of developing a curriculum. In future studies, we intend to propose guidelines for designing educational manuals and specific curricula for each educational target to cope with the climate change of cultural heritage presented in this study.

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.

From the Asia Cooperation Program on Conservation Science(ACPCS) of National Research Institute of Cultural Heritage(NRICH), I gained conservation and management experience and knowledges which are highly applicable at the Vat Phou World Heritage site. Firstly, Check list, Mapping, Tape Test and Digital Image Analysis are simple and useful methods which can be introduced to the site directly. If we can get chance to learn more about GIS program, GIS based Database Management System would also be very liable to put into practical use since the site office has been already using the program for general purpose. Lastly, there are more other methods which can diversify the studies on cultural heritage conservation in Laos; Rebound Hardness Test, Ultrasonic Test, Infrared Thermography, XRF Analysis and Hyperspectral Image Analysis etc. To realize those research however, new equipments are needed along with proper education so more cooperation between Korea and Lao would be essential.

The National Research Institute of Cultural Heritage(NRICH) conducted the Asia Cooperation Programme in Conservation Science(ACPCS) to facilitate and promote the regional cooperation in the conservation of cultural heritage among Asian countries. This course was promoted to provide an opportunity to study and work together, also to share a knowledge and experience in conservation field. The target countries were from 17 Asian countries, and this year our selection committee selected 2 specialist in cultural heritage conservation field and selected persons had participated in the ACPCS course during three months. NRICH provided the round-trip airline tickets, overseas travel accident insurance and a living allowance to the course participants. And we requested programme announcement to Korean National Commission for UNESCO and Ministry of Foreign Affairs and Trade to progress favorably. This course period was three months from 29 August to 25 November, and the fields were conservation and restoration of tangible cultural heritage such as metal conservation, stone conservation, material analysis, DNA analysis, dating, biological control management of cultural heritage, environmental monitoring and so on.

This research discusses the necessity for change in the domestic digital cultural heritage education. In following, this research analyzes definition and categories of digital cultural heritage education alongside with several case studies of global institutions and their characteristics. Throughout the analysis, this research suggests a direction of domestic digital cultural heriage which has limitations. Currently domestic use of digital cultural heritage education is currently limited to applying digital technology. Analysing literature review and case studies, this research found that digital cultural heritage education can make learners be mature in perspective of historical thinking and digital literacy simultaneously. In other words, digital cultural heritage education should not aim at pursuing education via digital platform simply, but rather fundamental cultural heritage education based on understanding of digital technology and future trend of education such as informal learning. Throughout the analysis of current cases and suggestion for future direction, the research aims at being a fundamental study of digital cultural heritage.
