The Mireuksaji stone pagoda is constructed Baekje Period in the 7th century which is located in Iksan, Korea. This stone pagoda designated by National Treasure No. 11 is the only remaining pagoda. This pagoda has lost the original form in part and the whole stonework wase dismantled. Work for the restoration is currently in progress. This study was divided into soil strata such as construct layer of the temple site, foundation layer of the pagoda basement, and construct layer of the stylobate by stratum to interpretation the skill of rammed earth and making techniques. The of physical, mineralogical and geochemical characteristics of soil samples were identified. Five pieces of soil in and around the Mireuksaji temple site was selected for the comparative study to interpretate the mutual homogeneity among soil stratum. As a result, artificial addition has not been identified in all soil samples using rammed earth. The soils used for the basement of the stone pagoda (construct layer of the temple site, foundation layer of the pagoda basement, construct layer of the stylobate) were confirmed to be the same origin as soil in and around Mireuksaji temple site. Thus these results indicate that the basement of the pagoda was constructed using soils in and around the Mireuksaji temple site without work as careful selection.

This research aims to examination the material characteristics changes of the ancient clay depending to firing temperature and to verify the firing temperature of the Joseon potteries from the Yongam site in Ssangyongdong of Cheonan, Korea. To this study, we conducted a firing experiments using the ancient clay that was verified raw material of the Joseon potteries from the study area in the temperature range from 500 to $1,200^{\circ}C$. The yellowish tint, the reddish tint and the specific gravity of firing samples increase according to firing temperature rise. But the absorption ratio and the porosity decreased under same firing temperature range. The soft potteries from the Yongam site has similar material characteristics with the fired samples at 800 to $950^{\circ}C$. And the hard potteries from the Yongam site bears the same relation to the fired samples at about $1,100^{\circ}C$. This result is considerably signification for the interpretation of firing temperature. The geochemical characteristics of the original clay according to the firing experiments, on the other hand, is not affected of temperature in this study.

Daejiguksaptapbi (Tapbi) is a memorial stele which is inscribed with personal history of a state preceptor, Daejiguksa Beopkyeong. The Tapbi comprises tortoise-shaped pedestal, dragon top and body stone, and the body stone is remained in 255 pieces by excavation in Samcheonsaji temple site of Seoul. The Tapbi is composed of tuffaceous breccia for the body, coarse-grained pink feldspar granite for the pedestal and fine-grained granite for the top. As a result of geological survey to find a rock provenance of the Tapbi rock, the tuffaceous breccia is found in the banks of Gangwha straits, and the pink feldspar granite and fine-grained granite are found around the temple site in Mt. Bukhansan. Each rock shows similarities to the Tapbi in lithology and mineralogy. Also, geochemical data of major, some trace and rare earth elements verify their cognation in each rock type. It can be interpreted that the provenance of the body stone is distant as Gangwha area, and the provenance of the pedestal and top stones are near the temple site. The results can be utilized to restore the Tapbi by using the same rocks.

The pupose of this study was to identify the material characteristics, firing environments and making techniques for the jar coffins from the Oryangdong kiln site and the Ungokdong tomb site in Naju. All jar coffins had very similar physical, mineralogical and geochemical characteristics, although it was excavated from the different sites. The wall thickness of the jar coffins was about 2.3 to 5.3 cm. Under the microscopy, the jar coffins include a large quantity of various quartz with some microcrystalline and showed partly orthoclase and biotite. It is presumed that the mineral sherds added to maintain the thick wall and to control the percentage of contraction during drying and firing of jar coffins and it has contained about 11.4 to 19.8 %. Firing temperature of the jar coffins is estimated as 1,000 to $1,150^{\circ}C$. Also, all jar coffins and soils show similar geochemical behavior of elements and clay-mineralization degree within the site. This indicates making that the soil is probable to be a raw material of the jar coffins. But it shows different characteristics in major elements of soils which is collected at the kiln floor and the trench region of the Oryangdong kiln site because of the lack of quartz and feldspar in the soils. Therefore, it can use of the jar coffins making clay, if it goes through a simple special process such as mixing temper.

As the tangible evidence, documentary art records are permanent records to reflect the historical, symbolical, cultural and artistic value. Also, documentary art records are related with mission fulfillment of public institution and it is documentary with administrative, cultural and artistic values as the works of documentary production and application of the administrative image. "The public records management law" was the first time that administration documents were incorporated and in the act No. 3 of administrative records management, the preservation and management system of documentary art records became legislated. The management of documentary art records are difficult to categorize only by the reflect of characteristics or materials. Because documentary art records are collected in many ways and made with materials. It needs to be collected with many informations on basic materials and with the appropriate conservation and management category. Documentary art records do not have lots of demands but the level of consciousness is improving and the possibility of opening to public is increasing for improvement with the right to know. In near future, the documentary art records will be used for the interpretation of historical and cultural preservation and modern cultural heritage could have the value as it is expected. Primarily to prevent deterioration on documentary art records the standard survey card should be made to categorize the damage rate and to check the status on each documentary art records. In addition, establishing a systematic management plan for various documentary art records are needed with the training of professionals for the conservation of documentary art records.

Chemical and Pb isotope analysis were performed in order to determine the origin of bronze artefacts excavated from the Inyongsaji site in South Korea. The result of ICP-MS shows that they are tin bronzes in which lead was not intentionally added during production. Pb isotope data analyzed by TIMS are plotted in the southern region of Korea and China of the distribution map drawn by Mabuchi(1985). On the other hand, the identical isotope data are plotted in the Taebaek basin and the Olcheon metamorphic belt correspondent to zone2 and zone3 respectively. It is believed that the isotope data on the tin bronzes which have very low lead content can be used to trace the origin of copper ore rather than those of either lead or tin ore. Pb istope analysis allows diverse interpretation as it can be applied to any object containing trace amounts of lead. In addition, accumulation of isotope data as well as further studies will improve reliability of the provenance studies.

The Stupa of the State Preceptor Jigwang from the Beopcheonsaji temple site in Wonju (National Treasure No. 101) was built in the Goryeo Period (around the 11th century), with very excellent style and techniques. It was returned to the Korea after being taken to Osaka of Japan without notice in 1912, and was severely damaged during the Korean War. Subsequently, the Stupa was restored using restoration materials like mortar, and relocated to the National Palace Museum of Korea. Surface contaminants in the Stupa primarily existed around the restoration materials. Black discoloration, which indicates a high discoloration grade, signified a high possession rate in the north and inner regions of the Stupa, which may be related to the relative moisture maintenance time. Most surface contaminants were calcite and gypsum; the black discoloration area underwent secondary discoloration due to air pollution. Moreover, the stone properties exhibited a relatively low discoloration grade, exhibiting crystallized contaminants that partly covered the rock-forming minerals. Overall, the Stupa deteriorated due to discoloration and being covered by lime materials, which were dissolved as the mortar degraded. Hence, it required contaminants removal, surface cleaning and desalination during conservation treatment, in order to control the rate of physicochemical deterioration by contaminants.

Pavilion is an important landscape installation in the traditional landscaping and a representative facility that organizes space. To interpret and succeed the traditional landscape space, researches on the shape and structure of the traditional pavilion are also needed. However, researches on the style and structure of the traditional pavilion are difficult to be found. Accordingly this study aimed to identify the structural characteristics of roof part that occupied the largest portion in determining the shape of pavilion. Our research findings are as follows. As a result of analyzing 15 traditional Single-room square pavilions whose structure could be identified, it was found that the main building elements that distinguished the type of roof part in the Single-room square were crossbeam, ridge pole, and baluster. Depending on the presence of roofing members, pavilion was classified into five types: crossbeam, crossbeam+ridge pole, crossbeam+baluster, ridge pole, and baluster. In addition, as a result of analyzing the load and joint that worked on crossbeam based on the shape classification of roof part, it was found that in the traditional Single-room square pavilion, crossbeam was designed to play a balancing role between pillar and load. This study is significant in that it attempted to make a close interpretation of the shape of roof part in the pavilion and the role and function of building elements in terms of size, ratio, and load.

The Sinamsa Temple was built in the late Goryeo Dynasty and a gilt-bronze seated Buddha is enshrined in Geungnakjeon hall in the precinct. Various damages occurred in the gilt layer of the Buddha, such as peeling of the gilt layer and deteriorating gloss. In the study, the conservation conditions of the inside and outside on the statue were accurately investigated, and the making technique was interpreted through the material characteristics and non-destructive diagnosis of the statue. As a result, it is estimated that gold-gilding layer is pure gold, coloration pigment of black is carbon, green is malachite, atacamite and verdigris, red is red lead and cinnabar, respectively. In the deterioration evaluation, peeling, cracking, break out and exfoliation of the gilt layer are confirmed as damages, but the conservation condition is relatively wholesome. However, the gloss of the gilt layer is calculated to be wider in the poorer part than the maintenance part. The ultrasonic velocity of the statue was calculated to be 1,230 to 3,987 (mean 2,608) m/s and showed a relatively wide range. In infrared thermography, peeling was not confirmed, and no special bonding marks were found. In endoscope, some biological damage and corrosion were observed on the surface of the internal metal, and sealed artifacts were identified. Manufacturing technique based on the study, it is considered that the gilt-bronze seated Buddha was cast at once, and the mold was inverted to inject molten metal.
