The standing plaster figure entitled is an early work from Choi Man Lin's 'Eve' series. It reflects the aesthetics of abstract sculpture in the period following Korea's liberation from Japanese colonial rule. Modern and contemporary sculptures can be made from a wide variety of materials, so the particular selection of materials and expressive techniques are indicative of both the artist's intentions and the zeitgeist of the moment. In this regard, the materials and production techniques used in provide important basic data for the chronological study of Choi's artistic development. In this study, scientific analysis was conducted to reveal the production techniques used in the work. The scope of appropriate conservation treatment was decided through consultation between several people with decision-making authority. First, the internal structure was inspected using X-CT scanning, and a material analysis was conducted to identify the formal characteristics, materials, and production techniques found in the work. As the analyses revealed the work to be in a relatively stable state, only minimal conservation treatment was applied based on the opinions expressed by the institution housing the work, by a former assistant of the artist, and in an interview granted by the artist during his lifetime.

The 'artist's intention' plays an important role in the conservation process of contemporary art. Accordingly, the information on artworks owned by the artist, their bereaved family members, and foundations that have decision-making power is important. The artist's interview is the kind of data that can clear 'artist's intentions' to ensure reliable conservation treatment can be carried out even after the artist's death. Therefore, this study attempted to use information from the artist's interview on the type of wood in the manufacture of the filler required for lifted and separated bark conditions in the conservation process of wooden artwork in the National Museum of Modern and Contemporary Art. While the conservation treatment resulted in the stable preservation of the bark of artwork, an analysis of the wood confirmed that the information in the artist's interview was not true. Consequently, we suggest that attention must be paid toward the information provided by artist, their bereaved families, etc. Based on the result of this study, this is also expected to help preserve upcoming artworks with similar bark conditions.

This study analyzed the composition and structure of materials with Buddhist paper scriptures excavated from architectural sites in 'Sum Tolgoi' of the 17^th century and carried out conservation treatment base on the result of the analysis. The scriptures were covered in dust and foreign sub stances, and were so crumpled that it was impossible to identify the form. The damage, loss, and discoloration have been identified. Buddhist scriptures written in Tibetan used indigo and ink sticks on paper as a result of UV-Vis analysis, and ink sticks as black character materials from scriptures written ancient Mongolian. SEM-EDS and Micro-XRF analyses revealed that the outlines were drawn with red lines using a mix of Minium (Pb₃O₄) and Cinnabar (HgS), or Cinnabar (HgS) alone, and the contents of the scriptures were written with silver paint. Silver chloride (AgCl) and Calcium (Ca) were identified in the silver paint component of the characters, while Calcium and Orpiment (As₂S₃) were identified in the yellow lines. Concerning the paper ground, Buddhist scriptures written in ancient Mongolian were characterized by herbal plant fiber and bast fiber, and those written in Tibetan, by bast fiber. Radiocarbon dating indicates that the paper for the scriptures was produced between the 15^th and 17^th centuries. Conservation treatment of the scriptures was carried out based on the experiment on the production of pre-coated paper and how to coat that to prevent the second damage due to the deformation and fragility of the excavated paper. The scriptures were preserved and mounted, and a neutral box was made to identify the contents of the scriptures recorded on both sides after the treatment. This conservation treatment is the result of a study that applied new conservation treatment materials and methods according to the principle of conservation treatment reversibility.

This study was investigated quantitative and objective making techniques for molding clay of Four-guardian statues in Songgwangsa temple. Also, basic data about the provenance of molding clay was acquired for the restoration using same materials when the conservation treatment is carried out. As a result, molding clay used the Four-guardian statues was identified the very similar soil regardless of layers and objects. But molding clay differed in particle sizes and contents of organic matters according to the first layer to finish layer in relatively thick parts. Also, it was used one kind of soil without the layer distinction in thin parts. The restoration soil was applied to genetically similar soil as molding clay of the Four-guardian statues, and showed a difference of careful selection degree according to the layers. As a result of the provenance interpretation, the soil distributing presumed provenance was confirmed the same origin as molding clay. Therefore, the soil is appropriate for the materials of conservation treatment. This result will contribute inorganic material research and conservation treatment for the clay molded Four-guardian statues in Korea.

The most ideal textile conservation is to block oxygen and light from historical textiles. However it is not possible because historical textiles should be examined, cleaned, restored, and exhibited to find out its historical value. Most of excavated costumes were severely stained and soiled. They are dark yellowish brown in color. To reduce the extent and intensity of the staining and to recover the original color of gray fabrics, bleaching would be required. Conservation treatment was carried out on the 8 historical costumes which belonged to General Duk-Ryung Kim(1567-1596). Two of them do not hold the fabrics. They hold only cotton wool and a little piece of fabrics. Even though these costumes underwent the conservation treatment in 1979, they were stained and needed re-treatment. This time, they were dual-bleached using hydrogen peroxide and sodiumborohydride followed by wet cleaning to reduce the soils and stains. The treatments improved the appearance of costumes. Through the analysis of the trace of fabric, carbonized fabric fragment, and fabrics remained in other garments, we concluded the missing fabrics to be ramie or cotton. It is different result from the primary report concluded to be silk.

Studies were conducted on manufacturing techniques by applying microscopy and conservation treatments on the annals of Joseon dynasty storage box at the National Museum of Korea. The results revealed that lime tree wood(Tilla spp.) was used to make the annals of Joseon dynasty storage box. Lacquering techniques were used to coat the box with a layer of lacquer and bone ash and then cover it with traditional Korean paper. After being covered with traditional Korean paper, more layers were applied in the following sequence: mud ashes, black lacquer, pure lacquer, and black lacquer. Before conservation treatments, some components and lacquer layers were missing in addition wood joint were loose. Therefore, conservation and restoration should be conducted based on the identified wood and by observing the shape of the remaining components.

This is a case study of conservation treatment of the textiles and costumes excavated from Soonchun Park's tomb in Eumsung, North Chungcheong province. When excavated, the objects were found fairly wet and badly smelled since they decayed in wooden coffin. They were wet-treated with deionized water to remove dirt and dried at room temperature, during which the objects were blocked and flattened to keep them in shape. Silk crepeline was under-layed and stitched to the damaged areas with silk-hair threads. Each costume was individually stored in a tray made of paulownia wood and flat textiles were rolled up in paper cylinders with 6 and 10 cm in diameter. Thymol was used to prevent microorganisms.

The gilded bronze Sarria reliquary(National Treasure No. 325-1) excavated from a five story tower in Songlim Temple is considered as a very important Sarria reliquary of Unified Silla Dynasty Kingdom along with glass Sarria containers excavated in package. It was found that this Sarria container was in a very weak condition in the conservation dept. of National Museum of Korea due to the wearing of the inside wood and the decay of the gilded bronze, so a conservation treatment was conducted by focusing on the prevention of further decay and wearing. Also because there is little information about Sarria reliquary, detailed investigation by means of precision actual measurements, microscopic examination and X-ray photography was carried out.

The Conservation Science Team of the National Museum of Korea has carried out the conservation on the mandolin-type bronze sword that was excavated from Weolnae-dong, Yeosu as had been requested by the Research Center of Dolmens in Northeast Asia. The mandolin-type bronze sword from Weolnae-dong, Yeosu is accounted to be the longest one among all the bronze swords of the same type that have ever been excavated until now and it was in a treated condition with the primary conservation treatment already achieved. Due to the corrosion in progress, it was in a very brittle condition being in two separate parts of the upper and lower parts. With the upper part exposed and the lower part with earth, they were urgently collected. The Conservation Science Team carried out the conservation treatment on them by connecting the lower part of the mandolin-type bronze sword to the upper part after making the lower part exposed, and then by using an estimated restoration method for lost portions. When carrying out the conservation treatment, the glass fibers of 10 wt% Paraloid B-72 (in Xylene) was used as a method for strengthening the brittle artifact, and a non-destructive analysis was carried out to identify the ingredients using the X-ray fluorescence spectrometer.
