The gilt bronze statue, Seated Avalokiteshvara with a Thousand Hands, of the Goryeo dynasty, is the only one in Korea of its kind that has undergone a conservation process for the special exhibition entitled GORYEO: The Glory of Korea. For the conservation treatment, first, a component analysis (XRF) was conducted, and a manufacturing technique (CT) was analyzed. The results of the investigation revealed that the statue was alloyed with Cu, Sn, and Pb ternary bronze. Its surface, except for the detached plating layers, was originally plated using the mercury amalgam method. This statue was assembled after separately casting each part of the body, such as the left and right arms and the wrists, including the hands, with objects. In particular, each wrist was cast and fitted with a metal nail to express each object in the hands more precisely. Inside the statue, there were five iron cores: two for the head, one for the left elbow, one for the right flank, and one for the right waist. For the preservative treatment, natural adhesive agents, including vegetable gelatin and glue (20%), were mixed with alcohol to protect the base metal and adhere to the plating layers. Using synthetic resin (CDK 520+SN-sheet) for the damaged parts, the restored parts could be attached and detached to/from the statue. Eventually, the compositional analysis and conservation treatment left the statue in a stable condition and ready for exhibitions and future studies.

지역 박물관은 대도시의 대규모 박물관에 비하여 전시물의 양과 질 그리고 관람객의 접근성에 있어서 열세에 있다. 이러한 가운데 최근 과학기술 문화사업 시행계획에 의한 중점 추진 전략으로써 지방테마 과학관 지원사업이 실행되고 있다. 지역 박물관중 특히 과학관은 어린이와 청소년층의 교육에 크게 도움이 되는 전시를 특징으로 하며 현재 세계 각국에서 다양한 주제로 관람객의 방문을 유도하고 있다. 이러한 기초 조사를 통해 지역의 문화유산을 보다 잘 보존하고 지역 문화 발전과 지역경제에 이바지하는 시설로 자리 잡는데 필요한 마케팅의 디자인 요소를 분석하고 살펴보고자 한다.

Some of the metal cultural heritage that make up a considerable proportion of Korea's cultural heritage have been installed and displayed outdoors due to their own functions, roles, and scale. Therefore, more diverse and complex damages can occur outdoors than they are in a stable environment. Therefore, it is necessary to combine accurate diagnosis and systematic survey methods in order to utilize basic data obtained from research results as data for the long-term and continuous conservation management as well as to do the research to diagnose the conservation status of outdoor cultural heritage. The clepsydra(hereinafter referred to as Jagyeongnu) of Changgyeonggung Palace, the National Treasure has been installed and displayed outdoors since it was manufactured. Though regular conservation and maintenance of the Jagyeongnu have been carried out, damage still occurred. Therefore, the scientific research on Jagyeongnu to diagnose the state of conservation was conducted prior to the full-scale conservation treatment. First, the state of conservation was investigated with an examination of basic data, macroscopic inspections and past records of repair history according to the purpose of the research. More detailed examinations were also conducted through the 3D scan, surface pattern investigation, and color difference analysis, and the analysis on materials and contaminants were conducted through P-XRF, FT-IR, and Py-GC/MS. The scientific research reveals that squalane and silicone oil have been applied in the past for conservation treatment and directly exposed to outdoor environmental factors, which caused damage to Jagyeongnu and contaminants such as dust adhered thickly to its surface, accelerating severe damage. A greater incidence of damage was found around the part with relatively high exposure effect, which corresponded with the tendency identified by grouping color difference data. As a result of integrating various research methodologies to diagnose the state of conservation and secure basic data, the causes and types of damage were identified. Furthermore, the process of obtaining digital data to be utilized in various ways, and the color difference analysis presenting visible damage as scientific data and identifying the tendency of damage patterns were confirmed to have been effective.

The Bracket clock in the collection of the Korean Christian Museum at Soongsil University underwent conservation treatment for a special exhibition. The compositional analysis showed that the body was made of brass plated with gold by fire-gilding(gold amalgam process), while the dial was identified as pure copper coated with enamel. The hands were made of steel. Remnants of adhesive tape on the dial were cleaned, followed by the addition of a protective coating. In order to restore it to a condition as similar to its original form as possible, replacements for missing parts were newly constructed out of brass and were connected to the hands and the dial. The dial was then fixed to the body using an acrylic support. The compositional analysis and conservation treatment have left the clock in stable condition and readily available for exhibitions and future studies.

Most preceding studies on museum lighting have focused mainly on illuminance, however this study examines diverse lighting characteristics, including illuminance, luminance, color temperature, and color rendering to allow a more objective evaluation of museum lighting. In particular, issues with existing museum lighting were examined through visual measurement to find an appropriate condition complying with museum lighting standards while providing a pleasant lighting experience for visitors. Although the top priority of museum lighting is to safely protect collections on display, lighting that takes into consideration luminance, color temperature and color randition will allow more effective appreciation as well as safe conservation of the exhibits.

The immersed ancient wood relics excavated from the low swampy area of historic site in Shinchangdong, Gwangju are extremely weak. Since they are quickly dried inducing shrinkage when exposed to air, special preservative treatment is required to exhibit and preserve such items. In the case of the heavily varnished lacquerware such as the lacquered sheaths, in particular, it is extremely difficult to preserve them because chemicals are not easily penetrated and the coating might swell or come off during the process of coating. The lacquer sheaths have been preserved by carrying out freeze-drying after impregnating them in aqueous solution with low concentration of PEG#4000 40%.
