As a leading institution for conservation science in Korea, the National Museum of Korea (NMK) has conducted diverse efforts in this field through conservation treatment, analysis, research, and other relevant affairs over the past four decades. However, conservation science at the NMK has been facing difficulties due to insufficient human resources for handling its extensive collection, decrepit equipment, an expanding number of requests for support from other institutions, and increasing calls for enhancing its functions. In view of these challenges, this study diagnosed the current situation and examined the functions required in order to suggest plans for the development of conservation science at the NMK. In this regard, it reviewed current activities at the museum and conducted case studies of overseas institutions to propose five functions to be enhanced or introduced at the NMK. First, the NMK should refine the existing functions of conservation treatment and enhance its support for conservation science. In addition, it is recommended to introduce and develop advanced analysis and diagnosis involving valuations, conservation environment management to counter climate change, and content-based digital conservation/restoration. The functional enhancements and introduction of the new functions as described above would help the NMK develop into a leading center for conservation science in Asia.

Scientific studies of conservation techniques and materials in Korea have experienced fast development since international practice and academic knowledge have been introduced to Korea from Japan, France, Germany, and etc from the late 1960s. In recent years, it has been observed that the academic standard of research and the level knowledge of the field in Korea at present are far advanced to compete with many countries. However, many Korean cases still have displayed that the standard and the quality of conservation practice need to be improved. This research examined several cases of derelict restoration of metal relics executed by non-conservators and the effects of their ignorant use of irreversible materials on the valuable objects. The purpose of the study is to display the problem of such treatments and to suggest a need of framework to prevent the loss of original form from them. Metal Buddha statue (Cosmic Buddha) in Borim Temple (National Treasure No. 117), which was conserved by an unexperienced non-conservator, has suffered from a serious problem of corrosion because of the use of destructive material, iron chloride. Another case for metal Buddha statue in Dopian Temple (National Treasure No. 63) displays a representative example of using irreversible materials, Cashew and such ignorant application made a later conservation treatment so difficult in removing the material from the surface of the statue. In conclusion, the research argued that the understanding of materials used in the objects, and the value of relics is important, and pre-experiments before applying conservation materials to a valuable heritage are essential in the conservation treatment.

Conservation re-treatment of dagger and scabbard in Gyeongju National Museum, which were excavated from Gyerim-ro Tomb No. 14 (Treasure No. 635) was carried out after a wide-scale dissembling in order for publishing a report and holding a special exhibition. The interior shape of the iron dagger which was disclosed by ornament plates was confirmed by X-ray investigation. The results of XRF analysis which was used to analyse compositions of the golden ornament plates reveal that having more than 3% of copper distinguishes it from other Silla gold artifacts. The conservation treatment progressed in a way that surface contaminants were removed and insecure areas were consolidated. The original shape of the iron dagger and scabbard was found after adhering and restoration. With the ornament plates staying on the iron dagger, a stand in acrylic for display and storage was made, which is able to place the dagger and scabbard in the safest way.

The conservation treatment and production technique of Yongmuntujoeunpanpi-Angyo(Saddle Ornament) at Hwangnamdaechong were: The conservation treatment removed foreign material by using both chemical method and physical method to reinforce and to recover area by jointing that was destroyed and weakened. Not only Angyogeumgu but also Jwamokseongeumgu was made of 99wt% or more silver (Ag), and Wondujeong, Naeyeongeumgu and Bokryung were produced by amalgam gold plaiting. Not only Angyogeumgu but also Jwamokseongeumgu that was cast with silver plate was jointed by folding both and putting Naeyeongeumgu on it and then nailing gild ofwondujeong at specific interval. A tree that grew up in curve was used, and it was adhered by plain weave fabric of hemp cloth and wool.

This paper describes the restoration and display of a large jar coffin at the Naju National Museum. Excavated from Tomb No. 3 at Bokam-ri, Naju, the large jar is 194 cm in height and its rim diameter is 108 cm. The jar had been broken into approximately forty fragments prior to its restoration, and a supporting structure was installed to ensure the safety of the relic during the restoration process. The restoration was conducted inside a visible storage for large jar coffins for approximately three weeks from February 5 to February 27, 2018. Over two weeks during this period, the restoration efforts inside the storage were visible to the public in the permanent exhibition space so that visitors could observe the process in person. This was planned to help visitors understand and arouse their interest in large-sized relics such as jar coffins and the restoration process. This study also investigates the practices of overseas institutions in order to suggest plans for raising public awareness of conservation treatment at conservation science centers.

"Buliseonrando," meaning "Buddhist virtues and the orchid are one and the same," was painted by Chusa Kim Jeong-hee. Four appreciation sentences are written in various fonts around the orchid drawn in the center of the painting, along with a total of 15 seals stamped. Hyperspectral image analysis(HSI), microscopy, and X-ray fluorescence (XRF) were conducted with a focus on the seals and the parts of the painting that have been applied with a conservation treatment. As a result of the analyses, the seals were classified into two types-seals with or without barium content. Stamp shade was identified only in five of themstamps, which allows the assumption that the composition and material characteristics of the stamp inks varied depending on the period. In particular, hyperspectral image analysis confirms traces of conservation treatment on the seals and the lost parts identified in addition to the 15 seals, which also demonstrates the utility of hyperspectral image analysis.

The celadon jar with inscription of 'the Fourth Sunhwa Year' is an important chronology that shows the conditions of production of the early celadon due to the inscription on the bottom including its purpose, application, and the producer. This celadon jar has been restored several times in the past. However, concerns over the structural stability, such as the separation and level differences in the joined cracks, have risen because of the aging of the repair materials, which were subjected to various environmental changes over a long time. By examining the conditions of preservation, the major damage was identified as the '入' shaped crack on the front, the 'V' shaped restored part and the crack on its left side, and the 'J' shaped crack on the back side. In the past, the cracks were found to be joined using a refined lacquer containing camphor, drying oil, rosin, etc. mixed with soil powder. The joint line was repainted with the refined lacquer and covered with gold powder. The missing parts were restored with gypsum and colored with acrylic color. After that, the repair materials were aged and emergency treatment was performed at the National Museum of Korea in 1981. At that time, Cemedine C or Cemedine C mixed with microballoons was used for reinforcing the cracks. Conservation treatment focused on removing the past repair materials and reinforcing the physically fragile parts by joining and restoring them based on the examination of the preservation condition. in addition, the area around the restored part was colored for future exhibition.
