Conservation treatment was done for the pottery-stand of Kaya period which was to be exhibited in celebration of the opening of Kimhae National Museum and for the jar of Chinese celadon which was to be exhibited in Korea National Museum's special exhibition "Formation of Ancient States". Through the examinations by naked eyes and under the microscope, condition before treatment, patterns and manufacturing techniques of the objects were observed. According to these examinations, conservation treatments, suitable for each object was finished. As the pottery-stand was damaged severely, the epoxy resin was pasted directly on the broken surface of the pottery to restore the original shape and pattern, color and feeling similar to original state were given to the restored area. Although same restoration material was applied on the celadon, it was not pasted directly on the broken surface of the celadon so that the restored area could be dismantled, and color and feeling were also treated somewhat differently.

This study was conducted to analysis and conserve a lacquered sheath excavated from Soochon-ri, Gongju, Korea. The lacquered sheath was collected together with iron relics. The lacquered sheath was damaged and lost the parts by the external pressure. Many parts were adhered with the rust. Firstly, the object was understanded to have the relation with the iron materials excavated together through the X-ray photographs. As the analysis of the lacquer layers, the report conducted to a study the method of production. After the analysis of relic, the conservation treatment was performed for the stability of original shape. And we made the protection frame for the storage and exhibition.

For exhibition, conducted conservation treatment for a variety of collections acquired at home and abroad such as metallic objects, wooden-ware, paintings and lacquer-ware. Conservation treatment methods for 42 metallic objects were introduced for material types. X-ray and microscopic method were used to identify the current state of the collections and in some case if necessary, various foreign particle removing and stabilization method were used depending on material type. Historical data were stored and exhibited to public.

To extend the application of digital technology to the replication of artifacts, meticulous details of the process and the diversity of three-dimensional (3D) printing output materials need to be supplemented. Thus, in this study, a bronze mirror with Hwangbichangcheon inscription was digitalized by 3D scanning, converted into a voxel model, and virtual conservation treatment was performed using a haptic device. Furthermore, the digital mold of the bronze mirror completed by Boolean modeling was printed using a 3D sand-printer. Such contactless replication based on digital technology reflects the stability, precision, expressivity, collectivity, durability, and economic feasibility of artifacts. Its application can be further extended to cultural products as well as such areas as education, exhibition, and research. It is expected to be in high demand for metal artifacts that require casting. If empirical studies through experimental research on casting are supplemented in the future, it could extend the application of digital technology-based contactless replication methods.

We proposed that the replicas be made as an alternative to achieve such reciprocal goals as the safe preservation of traditional costume relics and socio-educational realizations through exhibitions, etc., A replication was categorized for its purpose into a restoral replication a work based on the historical research of color and shapes as they were originally made and a current state replication . a production based on a minute record of the relics as they are excavated Then, we reported the reproduction process from the excavation to the exhibition on the excavated traditional costumes of Milchanggun's Jobok The purpose of a replication of relics is to record the relics experiencing the change resulted from the inevitable degeneration over time as organic cultural assets together with the substitution exhibition of relics and academic researches and so on. Accordingly, the above two methods are to be preceded by a deep and through research and study on the relics of replication. This study on the relics having an important cultural property value presents the preservation of tile cultural assets of traditional costume through the two replication processes and results and a flew pattern of exhibition.

Among many artifacts donated by Yoo Chang-jong, we duplicated and performed conservation treatment for a colored brick(J3432), a roof tile with monster-mask design(J1886) and a mould for roof tiles with monster-mask design(J1882). We focused on the restoration of the paint layer for the colored brick. As for the roof tile with monster-mask design, we cleared the existing poorly repaired part and then performed a complete conservation treatment. We would like to present the process to duplicate a roof tile with monster-mask design using a real mould, for the special exhibition entitled "Donated Tiles of Yoo Chang-jong".

The wooden lacquer wares, which had excavated from the water reservoir in the Isong Sansung Fortress, were applied with vacuum freeze drying method and treated, after they had been substituted with tbutanol, and treated with PEG-pretreatment. The manufacturing technique, which had not been investigated in the past, was examined through the investigation of the wood and the lacquer used for wooden lacquer wares, and the pieces of the lacquer wares, which had been stored for a long time, were restored for the exhibition and conservation. As the result, the wooden lacquer wares were manufactured, using black alder belonging to the group of Alnus, and the lacquer was painted on the bottom-layer by mixing the powdered soil and lacquer, and it was confirmed that the lacquer mixed with the black pigment and the pure lacquer had been painted alternatively over 2 times, and that the wooden lacquer ware had been manufactured through total 5 times of being painted.

Here is an introduction of the conservation process and storing method of 26 garments for exhibition among the excavated garments of Cheonngyeongunju(a princess) preserved in the National Museum of Korea. Before processing, the artifacts were investigated to find out the type of material and the damaged parts, and then surface and wet cleaning were conducted. After that, it were dried and fixed while held by hand for stability of the artifacts. When stored, the artifact was folded minimally in large parts to prevent damage and placed in a neutral box with buffers in between.

The Bigyeokjincheolloe (bomb shell), a scientific cultural heritage, has outstanding historical value for sustaining a gunpowder weapon of Joseon. In this study, the bomb shell was modeled through three-dimensional (3D) scanning centered on the external shape and 𝛾-ray radiography-based on the internal shape. In particular, to improve the contrast in the radiographic image, optimization and image processing were performed. After these processes, the thickness of the inner wall (2.5 cm on average) and the positions of the three mold chaplets were clearly revealed. For exhibition purposes, the 3D model of the bomb shell was output to a 3D printer and the output was rendered realistic by coloring. In addition, the internal functional elements, such as Mokgok, fuse, mud, gunpowder, and caltrops, were reproduced through handwork. The results will contribute to the study of digital heritages in two ways. First, the internal and external shapes of the bomb shell were modeled by fusing two different technologies, namely, 3D scanning and 𝛾-ray radiography. Second, the internal shape of the bomb shell was constructed from the original form data and the reproduction was utilized for museum exhibitions. The developed modeling approach will greatly expand the scope of museum exhibitions, from those centered on historical content to those centered on scientific content.

Disassembly and restoration work of Janghang-ri Stone Standing Buddha in the outdoor exhibition hall of Gyeongju National Museum were conducted for safe management of the collection due to problems like weathering of bonding materials by the outer environment, fixation of pollutants on the surface, and cracks by unidirectional load of rocks. A drawing was made through three-dimensional precise actual measurement, basic material research was conducted, and cement mortar and resin of the weathered part were removed. The restored part was bonded and restored by new stones using the same kind of rock. In addition, in order to prevent damages from microorganisms, fumigation treatment was made. It is under continuous observation.
