Understanding the whole knowledge of ceramics is essential for a person in charge of conservation of ceramics since their methods of manufacturing or materialistic features have very close relationship with their damaging process. Also, various executions of repair and restoration dealing with any damage in use have to be looked into. The information attained through those studies finds damaging causes of ceramics, which becomes a critical element when choosing a proper conservation treatment method and utilizes as indispensable data for permanent preservation. As part of scrutinizing materials of repair and restoration, this study examines the purpose, date, and the constituents of the materials used in metal bound rims adhered to the brim of ceramics. Among the subjected ceramics, the metal bound rims possible to scientific analysis were gone through element analyses with Portable ${\bullet}\"{I}$-XRF Spectrometer and SEM-EDS while the ingredients of the ceramics difficult to analyze were inferred by eye inspection of exhibition catalogues. The results of this study confirm that metal bound rims consisted of diverse materials were adhered to the brim of ceramics.

Conservation Science Lab. of the National Museum of Korea recovered Bamboo-plated inkstone case which is used for keeping inkstick, inkstone and inkstone water container by using traditional lacquering and wooden art technology. Texture and construction method of wood, ingredients for lacquering and the method, and the design were analyzed in order to restore the original manufacturing method. Especially, perfect restoration of partially damaged lacquer surface is the most important aspect in restoring Bamboo plated inkstone case, therefore focus was put on investigation of surface lacquering. First, lacquering surface sample was taken off from the object and processed into flake and observed with transmission microscope in order to investigate lacquering method and the pigment in the lacquering surface was analyzed with XRD and SEM-EDS. The result showed that the object was decorated with thin-layered bamboo in the surface which is made of Royal paulownio. and lacquered several times with the mixture of Hematite(Fe₂O₃) and Cinnabar(HgS) in the remaining part.

This study explores the effects of X-ray irradiation for biological control and high-temperature degradation on dye stability in dyed textiles with Gardenia. To evaluate this study, optimal extraction solvents for these textiles were identified by comparing them with a crocin standard solution. Extraction using pyridine closely matched crocin. The study then assessed the stability of X-ray irradiation and high-temperature degradation on these textiles. Transparent yellow dyes were observed in all samples. Color differences were found to increase at higher irradiation doses and longer degradation periods. While UV spectroscopy spectra showed broadening and lowering trends with higher irradiation doses and longer degradation periods, suggesting a reduction in colorant transition, mass spectrometry revealed minimal chemical changes. In conclusion, both X-ray irradiation and high-temperature degradation induced spectral changes without complete dye decomposition. Major colorants were consistently detected.

This work aims to clarify the character and selection of repair papers, based on fibre orientation information of paper cultural properties under restoration; using nondestructive image analysis applied to micrographs of paper surfaces. Image analysis using fast Fourier transform with suitable modifications was demonstrated to be an effective means to determine angle and intensity of fiber orientation as a nondestructive method. In the case of contemporary repair papers, the Japanese handmade paper exhibited a high anisotropy value, while the Korean handmade papers exhibited low anisotropy values. Korea and Japanese traditional hand making papers were well distinguished. Korea and Japanese papers made in the traditional ways showed its own characteristic orientation behavior in accordance with the motion of a bamboo wire.

Korean Paintings have been drawn on in the main two types of support material - paper and silk. In these things, silk designates picture silk, that of a specially weaved textile for painting since CHO-SUN dynasty, different such as hemp, ramie have been started to use for support material In addition to picture silk. However the structure of hemp and ramie are so close and progue, They are not proper to express the technique of pigments on the back of the paintings. On the other hand, picture silk is efficacious in pigments on the back of the painting with its interval between the strands and translucent textile. As the result, paintings on the silk has many - sided techniques as compared with painting on the papers therfore various devices in conservation have to be considered to deal with the techniques. In this report the focus is on classifying the method of removing the Lining paper according to the several types of expression technique of paintings on the silk.

Modern and contemporary cultural assets are defined as a collective term for tangible historical and cultural assets produced in the modern and contemporary period (around the opening of Joseon to the present) in Korea. Among them, rickshaws have been used as a major means of transportation for about 40 years since the opening of the ports in Joseon. The repair process for rickshaws divides the rickshaw into three parts, namely the body, the cover, and the wheels, applying a plaster treatment process by referring to the outcomes of the condition assessment and material analysis for the metal, wood, fiber, and paint used. Overall, the repair process is carried out through dry/wet cleaning, joining, stabilization, reinforcement of damaged parts, and other restoration treatments, which reveal metal decorations and patterns on the scaffolding (flowers, arabesque patterns, etc.) that were previously not observable with the naked eye, while also adding to the stability of the artifact. In addition, props were produced to ensure the artifact's safe exhibition.

In order to use and conserve groundwater efficiently, in the first place the values of transmissivity and storage coefficient have to be correctly estimated. Various methods to determine hydraulic parameters of aquifer were reviewed and the characteristics of the methods were described in this paper. They were compared to obtaine parameters by various methods. An improved method to estimate the hydraulic parameters of aquifer is suggested by the comparison of the previous methods.

Two wooden fish excavated from Wiryeseong Fortress on Seonggeosan Mountain in Cheonan-si, Chungcheongnam-do Province were frail due to their deterioration within the burial environment. To prevent further deformation, conservation treatment was conducted on them to strengthen the wooden materials and stabilize the dimensions. Prior to the conservation treatment, the species of wood was determined to be pine and infrared Irradiation on the patterns remaining on the wooden fish revealed that they were depictions of carp. For conservation treatment, the wooden fish were impregnated with PEG #3, 350 in a water solution with a 40% concentration, followed by freeze-drying.

Koreans began to undertake the conservation of their art and architectural artifacts approximately fifty years ago after modern concept of conservation were introduced by japanese during the Japanese Colonial Period(1910-1945). But still the modern concept of conservation is not clear to many Korean conservators because they have been concerned about conservation techniques to recover the original from of the remains be destroyed. Also, Korean conservation practice has neglected the philosophical issues and ethics of conservation. So, in this article, I described various terms referring to 'conservation' which have been used in western countries, Japan, China, and Korea, and compared their similarities and differences to have more clear idea on the modern concept of conservation. In the next chapter, I summarized several theoretical issues which had been discussed among western conservators over the centuries. Specially, I described closely the modern issues and ethics which have been presented in the twentieth century. As many conservation projects in Korea have resulted unsatisfactorily or been suspended altogether, because lacking a coherent theoretical dialogue on conservation and discussing an ethical issues of conservation. Therefore, I believe that more vigorous dialogue on these issues in Korea may lead conservators to consider their tasks in a more productive light, and the Korean artifacts may preserve well.
