It is difficult to predict the kinds of damage to contemporary art because of the diversity of materials and experimental techniques used. This makes it hard to conserve. Furthermore, the artist's intention in contemporary art is emerging as one of the important issues to be handled in conservation treatment. Thus, collaboration with various stakeholders such as the artists themselves, bereaved family members, and foundations have become more important than ever from the viewpoint of planning conservation treatment. The trustworthiness of conservation treatment would be significantly enhanced if conservation treatment reflected the understanding and respect of not only the appearance of the work, but also the social/cultural context inherent in the work. This should be done, in particular, through collaboration with the artists. In this study, various case studies at home and abroad were analyzed as to explore collaboration methods with various stakeholders for objective and trustworthy conservation treatment. Along the way, the study raised the need to establish new conservation ethics for contemporary art. It is expected that the outcomes of the study could be used as basic material to preserve the originality of contemporary artwork and to set the direction for conservation practice.

In the conservation treatment of wood remains, polymers, treatment methods, and treatment period can be varied, depending on the percentage of moisture content and species of trees. Thus, in order to apply the appropriate conservation treatment, a lot of information from the wood remains are required. Despite the information from the wood remains, testing a part of the wood remains is necessary to get information about the polymers. When the wooden coffin made of camphor trees was excavated, it was cracked in the section of radiation, and there were hairlines cracks. Therefore, without any conservation treatment, it is impossible to restore it. This experiment is for the conservation treatment of the wooden coffin excavated from Songhyun-dong tombs No 7, Changnyeong. For this experiment, I used camphor trees from Jejudo. The purpose of this experiment is to asses the possibility of preliminary testing materials before the conservation treatment on the wooden coffin. After the camphor trees from Jejudo are artificially aged by Fenton's reagent, they are As a result of oxidation by Fenton, the degree of oxidation is high in proportion to the amount of peroxide and iron sulfate. Among several samples, the sample 'na' made the most similar result to the wooden coffin from Songhyun-dong. If I use this condition to make the sample in polymer tests, it is very helpful to find the most suitable polymer for the conservation treatment of wooden coffin. After the same species of trees are oxidized by Fenton and they become the similar condition, we are able to find suitable methods of conservation treatment. The suitable methods reduce the demage of the remains and make us to get more information. Thus, we are able to carry out conservation treatment more exactly.

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.

Conservation treatment of stone cultural properties in the open air is mainly conducted by companies specialized in conservation treatment. This study presents cases of conservation treatment of stone cultural properties housed outdoors in Seoul, including the Three-story Stone Pagoda at Nakseongdae in Gwanak-gu. The present condition of and damage to stone cultural properties are investigated and the materials and techniques used for conservation treatment are presented. The contamination on the surface of stone cultural properties located in downtown areas shows features specific to the related areas, meaning each case requires tailored conservation techniques. This study is expected to serve as reference for future conservation treatment of stone cultural properties in Seoul as well as others in museum collections exhibited outdoors. It is hoped that the cases presented in this study can become widely known to people in charge of conservation treatment in the private and public sectors to improve the quality of conservation treatment applied to stone cultural properties.

This study is about the conservation treatment from 2008 through 2009 of Gilt-Bronze Cap excavated from Andong tumulus at Guildu-ri, Podumyeon, Goheung, Jeonnan. The whole shape of Gilt-Bronze Cap was distorted and destroyed by the earth pressure. For the conservation treatment, first, soil and pollutants came from the findspot were removed. And then to assemble the whole shape of Gilt-Bronze Cap, we carried out the jointing work forming the shape after dismantling. Under that process, the rust of bronze was removed through the microscope at every moment and the gold-plated surface was revealed. Now the conservation treatment was completed and it is expected to perform the scientific research on the manufacturing methods and composition analysis of Gilt-Bronze Cap.

In November 2011, various artifacts were excavated from the No. 8 stone-lined tomb in Suchon-ri, Gongju by the Chungnam Institute of History and Culture. These included artifacts with lacquered mainframe and silvery metal ornament. These were recovered together with soil and underwent conservation treatment. In this paper, we discuss the scientific analysis and conservation treatment of the lacquered artifacts excavated from the Suchon-ri site. Among our findings is that the artifacts have three layers of lacquer coating and the metal parts are primarily composed of Ag. As the artifacts were recovered with soil from the site, the soil was removed from underneath and inside the artifacts. The inside of the lacquerware was reinforced with rayon paper using 3% funori, and the metal was treated with acrylic resin after removing the acrylic resin previously used to recover the artifact, followed by cleaning. The metal was also internally reinforced with gauze. Finally, the interior reinforcement was made using PVA and resin in pulp and attached with funori to preserve the shape of the lacquerware, and the exposed rayon was finished with acrylic paint. The main advantages of this study are its review of conservation treatment strategies for lacquer artifacts whose numbers have recently increased, and the application of new conservation treatment methods.

It is used for the epoxy resin, a mixture of various fillers conservation of cracks of the stone cultural heritage. Such as conservation treatment is need to for long-term conservation. However, field research and experiments on the conservation treatment results when included 54 cases of talc filler was confirmed that the damage, such as discoloration and cracks. The field research is talc was used to determine whether the reports and conservator interviews conducted, microscopy, ICP analysis of the samples collected from the field site. Experiments is color difference measurement and Ultrasonic measurement were arried out, and artificial weathering tests to investigate the effect of talc. As a result, lower the property of matter of the samples containing the talc. Therefore, we propose that the selection process is not allowed to use talc as the filler of stone powder filler cracks is conservation treatment.

Field experiments for Conservation damage on selected spots were carried out prior to direct conservation treatments for Bangudae Petroglyphs in Ulsan. It was found that there is a big difference in treatment effects according to the treatment technique and application rather than on the treatment material use. Based on the results of this study, a plan for the conservation treatment of Bangudae Petroglyphs will be suggested by providing new materials and application techniques for cracks, adhesive application and consolidation by conducting artificial weathering tests and continued monitoring.

In general, collections in museum are kept in storage according to a preservation and administration program in long or short term, after conservators' conservation treatment. Museum activities related to conservation science are common to do before and after exhibitions. That is, the museum collections include a flow mechanism, which circulate a space in where conservation science related activity is carried on centering around its storage. The purpose of this study is to suggest the design guidelines of a conservation area in a museum. The results of this study as follows. First, to program space planning, conservation area of museum is divided into 4 kinds of zone. Second, space for relics unloading in basically includes 'unloading room', 'control room', 'worker room', 'unpacking room', and 'unloading tools storage' and considers to install 'outdoor arrangement space', etc. In case of space for making relics collections, 'arrangement room' and 'temporary storage' are separately planned in order to arrange and temporarily store relics taken in. Conservation analysis space should be divided into 2 kinds of zone, 'conservation analysis lab' for analysis of collection characters and 'restoration lab' for conservation treatment in the bigger museum. In case of large-scale museum, conservation treatment space is basically classified with characters of museum collections. And it considers installing 'waterlogged wood lab', 'painting clothes treatment lab', 'storage of treated relics' etc. Third, for 'the spaces for analysis treatment', must consider activity contents and sizes of the department for scientific conservation every museum, can classify in detail required space, and must review the space for relics settlement in construction.

Paper relics, which are made of natural ingredients, are more likely to be damaged by a compendium of complicated causes (e.g., physical, chemical, and biological causes) rather than by a sole cause. In December 2009, Culture Heritage Conservation Science Center discovered several damages in paper relics related to Chungmugong Yi Sunsin, and requested for conservation treatment from the Hyeonchungsa Shrine office. By conducting a comprehensive research to determine the damage level of each artifact, the center was able to establish a proper conservation method, and for two years after its completion of such research in 2010, it has been conducting treatment. This study suggests the proper ways to select adequate conservation treatment based on the type of paper relics - Documents and Books - through the case of artifacts related to Chungmugong Yi, Sunsin. Even though the conservation treatment on paper relics can suppress damaging speed and prevent another damages, it is impossible to stop aging process of relics. Therefore regular inspection is essential for prevent second damage.
