We conducted optical microscopy, infra-red spectroscopy and SEM-EDS analysis of the lacquer layers on the wooden coffins excavated from King Muryeong's Tomb. We found four varnishing methods according to the sub-materials of lacquer layers: The lacquer of wooden coffins with black paint layer on the surface were classified with two groups; single layer and three layers. The lacquer of wooden coffins without black paint layer on the surface were classified with two groups; single layer and two layers. IR spectra of the laquer were same as those of the oriental laquer. The SEM-EDS analysis showed that the lacquer layers were mixed with iron, copper and calcium.

Analysis of the species of wood in the wooden materials and the chemical composition of the fabric of the clothing excavated from the tomb of Yi Jing (1580-1642) has determined that the wooden materials, including the coffin (內棺, naegwan), burial chamber(外棺, oegwan), chilseongpan(七星板, bottom-lining board), and fan-shaped slats were made of pine(Pinus densiflora). The analysis of the fabrics suggested that the cloth attached to the fan-shaped slats, the funeral banner with inscriptions, and the five pouches for the corpse (五囊, onang) were all made of silk. The jacket was made of plain-weave cotton, while the inner and outer cloth of the socks were made of cotton and hemp, respectively. Among the silk items, the pouches for the left and right feet (constituting the five pouches for the corpse) were made from a satin-weave figured silk, while the other silk items were made of ju(紬), or plain-weave silk fabric. Infrared analysis revealed that the fan-shaped slats were decorated with cloud patterns across the entire surface, while the funeral banner and the five pouches for the corpse bore ink inscriptions.

The essential point to be considered when restoring lacquered ware is to know its materials and properties, and prior studios from the conservational and scientific examination is the way to achieve it. Recently, to get a close examination of its materials and methods involved in lacquered ware making, cross section microscope studies are being applied. Cross section microscope studies shows that lacquering process has been simplified and that bone and earth substances have been added to the materials, a method also traced from the lacquered wooden coffin excavated from the 'Nak Rang Tomb' and by the lacquered wares of the 'Kyongjoo An Ap' areas. The significance of this Chosun Dynasty lacquered wares's inlaid with mother-of pearl restoration can be found in that we have been able to harmonize the very traditional and the very modern scientific method of our time and that we were able to launch a step forward from using only the synthetics to open up a new range of natural materials such as lacquers, bone and earth substances, oxhide-glue and nacres and of referring to the traditional methods.

Archaeological investigations carried out in the Chilgok Housing Land Development Area have identified large-scale settlements from the Bronze Age and Three Kingdoms periods. The settlement site in Dongcheon-dong, Daegu was found to include sites of pit dwellings, buildings with elevated floors, stone coffin tombs, wells, catchment basins, stone mounds, furrows, cropland, moats, and river channels. These findings offer insight into diverse aspects of settlements during the Bronze Age. This study analyzed the species of trees that produced the materials for eight wooden artifacts excavated from a Bronze-Age river channel site. The analysis identified two examples of Pinus spp., two examples of Abies spp., and four examples of Quercus sp. The three artifacts of undetermined use were made using wood from Pinus spp. and Abies spp. Among the five artifacts identified as building components, one was made from Pinus spp. and four were made from Quercus sp.

We have conserved the sword with round pommel with a tri-ring which was excavated from No. 1 tomb of the Duckcheon-ri at the Gyeongju and requested from Jungang Research Center of the Cultural Heritage. When this artifact excavated, it was pressed flat state because of the influence of earth pressure and stuck to a gravel and soil laid scattered on the wooden coffin. If the artifacts is handled without plan, it can be damaged, therefore that sword was collected together with soil using the Polyurethane foam. After the artifact which had a weak specific and was collected using a this method can be safetly collected as below; First, we made the supporter of article ordered using a silicon and gypsum. The silicon can conserve the weak point of the artifact because it has a flexible and smooth properties and the gypsum can adhere closely to the artifact because it has a little expansion and shrinking but a hard and fluid characters. Consequently, gypsum is a good complement to the weak point of the silicon. Second, During a remove gauze and a reinforcing agent from the surface of a artifact which was reinforced using a acetone steam method. The acetone steam method can be supplement to a dangerous problem of acetonedircet method because this can be damaged in a surface of the artifact.

This is a case study of conservation treatment of the textiles and costumes excavated from Soonchun Park's tomb in Eumsung, North Chungcheong province. When excavated, the objects were found fairly wet and badly smelled since they decayed in wooden coffin. They were wet-treated with deionized water to remove dirt and dried at room temperature, during which the objects were blocked and flattened to keep them in shape. Silk crepeline was under-layed and stitched to the damaged areas with silk-hair threads. Each costume was individually stored in a tray made of paulownia wood and flat textiles were rolled up in paper cylinders with 6 and 10 cm in diameter. Thymol was used to prevent microorganisms.

One piece of Haedong-Tongue(해동통보) minted at 1,102 A.D. was excavated from No.20 wooden coffin, Sinbong-dong, Cheongju. It was analyzed by micro-XRF and ICP and determined the concentrations of ten elements such as Cu, Pb, Sn, Zn, Fe, Mn, Sb, Co, As, Ag and Ni. The measurement of lead isotope ratios was also carried out in order to predict the provenance of raw materials used for minting of Haedong-Tongbo. It was found that Haedong-Tongbo was minted with three compositions of $Cu\;75.5\%,\;Pb\;13.3\%\;and\;Sn\;6.0\%$, which were different from the typical composition of Chosen-Tongbo and Sangpyung-Tongbo used in Chosen dynasty. Lead isotope ratios of Haedong-Tongbo showed that the provenance of lead used for minting of it suggested the possibility to be originated from Southern part of Korea.

This study set out to review tomb culture in the Gyeongju region during the Bronze Age, and also examine the patterns of dolmens during their end phase. For these purposes, the study analyzed 18 tomb relics from the Bronze Age and nine from the early Iron Age. Gyeongju belongs to the Geomdan-ri cultural zone. Approximately 120 tombs from the Bronze Age have been excavated in the Gyeongju region. There are fewer tombs than dwellings in the region, which is a general characteristic of the Geomdan-ri cultural zone. Although the number of tombs is small, the detailed structure of the dead body is varied. During the Bronze Age, tombs in the Gyeongju region were characterized by more prolific construction of pit tombs, dolmens with boundaries, and stacked stone altars than were the cases in other areas. There is a great possibility that the pit tombs in the Gyeongju region were influenced by their counterparts in the northeastern parts of North Korea, given the spindle whorl artifacts buried at the Dongsan-ri sites. Dolmens with boundaries and stacked stone altars are usually distributed in the Songguk-ri cultural zone, and it is peculiar that instances of these are found in large numbers in the Gyeongju region as part of the Geomdanri cultural zone. Even in the early Iron Age, the building of dolmens with boundaries and stacked stone altars continued in the Gyeongju region under the influence of the Bronze Age. A new group of people moved into the area, and they crafted ring-rimmed pottery and built wooden coffin tombs. In the early Iron Age, new rituals performed in high places also appeared, and were likely to provide venues for memorial services for heavenly gods in town-center areas. The Hwacheon-ri Mt. 251-1 relic and the Jukdong-ri relic are ruins that exhibit the aspect of rituals performed in high places well. In these rituals performed in high places, a stacked stone altar was built with the same form as the dolmens with boundaries, and a similar rock to the cover stone of a dolmen was used. People continued to build and use dolmens with boundaries and stacked stone altars while sustaining the Bronze Age traditions, even into the early Iron Age, because the authority of dolmens was maintained. Some dolmens with boundaries and stacked stone altars, known as being Bronze Age in origin, would have continued to be used in ritual practices until the early Iron Age. Entering the latter half of the second century B.C., wooden coffin tombs began to propagate. This was the time when the southern provinces, including the Gyeongju region, were included in the East Asian network, with the spread of ironware culture and the arrival of artifacts from central China. Around this time, dolmen culture faded into history with a new era beginning in its place.
