The purpose of this study is to establish the conservation methods of embroidered textiles and textile works. The conservation of remained textiles is consisting of examination, cleaning, support and consolidation, restoration, and storage and display process. It aims to prevent the damage on textile remains for long time display and storage and to prolong their aesthetics and functionality. The embroidered textiles and textiles works, which are remained by handed down or excavated or included in the Buddhist are embossed with colorful threads on the fabrics: the stitches include embroideries on clothing, bed clothes, wrapping clothes, utensil pouches, panels and Buddhist goods; textile works include hats, ornaments, shoes, attachments of clothes etc. These are composed of mainly fabrics, precious metals, leathers and precious stones, etc., and are fabricated by several techniques such as braiding, twining, sewing as well as weaving. Metal threads were also used to add a decorative effect on these goods. In order to conserve and preserve the remained goods, a special care must be taken on the metal threads, which are the most fragile material among the constituents. Hence, characteristics of metal threads and its cleaning methods, general conservation techniques of a rank badge, which is brocaded and partly attached to Cheogori and Samo(men's hat) from the excavated old tombs are introduced here.

This study was carried out to investigate the effect of artificial accelerated ageing treatment on the permanence of lining papers produced from Korea and Japan. As time gone by, organic cultural properties are affected by chemical and physical deterioration because of various factors including the conditions of preservation environment and their material properties. In the public historical storage or owned as private collections, are vulnerable to sever amages caused by poor preservation environment as well as by other natural factors. In this study, the deterioration behaviors of lining paper in optical & mechanical properties were discussed. Overall, lining papers produced from Korea showed lower reduction in mechanical strength properties compared to the lining papers produced from Japan.

We made biological investigation on the conservational environment of collections in the Ho Am museum. Annual average temperature and relative humidity outside the museum were $11. 0∼11.7^{\circ}C$ and 64.8∼74.4% respectivey. On the other hand, average annual temperature and relative humidity inside the main storage were $19.1∼20.1^{\circ}C$ and 53.0∼63.4%. We isolated fungi and classified into 8 genus 13species fungi and selected four fungi having high cellulotic activity such as Alternaria brassicae KCPRI 9202, Aspergillus niger KCPRI 9205, Aspergillusversicolor KCPRI 9206, Penicillium adametzi KCPRI 9208. These fungi were examined on the posibility of collections being damaged under current conservation al environment in the museum. KCPRI 9208 was non-tonophilic fungus and other were facutative tonophilic fungi. These showed maximal cellulotic activity of enzymeshaking culture at pH 5.0∼5.5 for 4 and 5 days. In proprtion to the period damaged, cellulase activity for paper damaged artifically with growing worse of material. As are sult cellulotic activity by fungi increased.

The copper incense burner inlaid with gold and silver and purchased by the National Museum of Korea in 2002 was to be corroded severely throughout the surface. It was difficult to recognize the part with silver inlaying. Using the abrasive method with alumina, however, its splendid inlaying patterns were restored. Prior to applying the abrasive method, the quality was examined, and a material that could help bring out the patterns without causing too much damage to the artifact, selected. The overall condition of the incense burner was also checked through X-ray equipment to know the condition of the gold and silver inlaying, and by x-ray fluorescence spectroscopy to confirm the composition of the incense burner and gold and silver inlaying. The result of this process is expected to serve as valuable data in future research on incense burners inlaid with gold and silver.

The early post-war modern architecture introduced to Korea in the 60's and 70's have reached its 50 year cycle to emerge as candidates for the registered heritage. However, conservation is a complicated topic when applied to modern architecture due to its social and political status among general public, and is often a sacrificial target for demolition or insensitive alteration. This research tries to identify significant values extracted from the intrinsic characteristics of modern architecture, that can be applied to conducting successful renovation projects on modern architecture. The conservational values of modern architecture to be maintained are identified in this paper as: flexible open space, material and structural system, and extension of interior-exterior relation. These values are examined through the filter of comparative analysis on domestic and international conservation standards, along with cross-examination on recently renovated local works performed on the modern architecture of the period. This research aims to bring focus on conducting respectful conservation and renovation to modern architecture by identifying the significant values that is intrinsic to the modern architecture and is worth preserving.

Disassembly and restoration work of Janghang-ri Stone Standing Buddha in the outdoor exhibition hall of Gyeongju National Museum were conducted for safe management of the collection due to problems like weathering of bonding materials by the outer environment, fixation of pollutants on the surface, and cracks by unidirectional load of rocks. A drawing was made through three-dimensional precise actual measurement, basic material research was conducted, and cement mortar and resin of the weathered part were removed. The restored part was bonded and restored by new stones using the same kind of rock. In addition, in order to prevent damages from microorganisms, fumigation treatment was made. It is under continuous observation.

Conservation science team of the National Museum of Korea has conducted conservation treatment for 3 pieces of portraits as a part of project for publishing illustration book of relics of paintings and writings. Among them, portrait scroll of Jo Gyeong is a representative portrait of Seonmoogongsin rank in 17th century of Chosun, which was donated in 1997 and its whole body painted on silk was scrolled. This portrait was in poor state including the silk of portrait got loose from lining paper completely and exfoliation of the pigments. Accordingly before preservation treatment, production technique and the quality of the material lining were surveyed through scientific study(investigation through microscope, XRF, X-ray) and preservation treatment was conducted in order of disassembly, cleaning, removal of lining paper, infiling of the missing parts, lining, finishing.

Stone cultural heritages are mostly situated in field, so they are damaged from mechanical, chemical and biological weathering, and their degree of strength is also weaken. Therefore, the scientific conservation of the stone cultural heritages are necessary in order to the long-term maintenance and safety conservation. In this study, we attempt to estimate on the field application of consolidants which are Wacker OH 100, Remmers KSE 300 and 1T1G according to the quality of the rocks. Based on the ultrasonic velocity, conditions of weathering damage before treatment are mainly ranked completely weathering condition (CW) or partly highly weathering condition (HW). After the first treatment, weathering damage conditions are changed by the high weathering condition (HW). These results shows that the internal pores of stone are filled with consolidant materials, so average ultrasonic velocities increases after treatment. And Remmers KSE 300 which is consolidant material is highest rate of increase of average ultrasonic velocities.
