  • This study was conducted to identify wood species for 51 excavated wooden shoes in the 12~16 Chungjin district of Jongno. Wood species of 31 Pinus sp., 12 Torreya nucifera S. et Z., 4 Ginkgo biloba L., 2 Salix sp., 1 Kalopanax pictus (Thunb.) Nakai. and 1 Morus sp. were identified. Wood used for wooden shoes was a species that can be mainly obtained easily around. Among them, Torreya nucifera S. et Z. grows in warm temperate zone of Korea, which shows that interregional cooperation has occurred.

  • During the repair and restoration of the Daewoongjeon Hall of Youngguksa Temple, species identification and tree-ring dating for both present wood elements and charred ones excavated under the Hall, were conducted. The species of 74 wood elements of Daewoongjeon Hall, were identified as Pinus densiflora Sieb. et Zucc. and only 1 was identified as exotic Pinus species. The latter wood, which was used in the laths, seems to have been replaced during past repairs. Many documentary records and various artifacts pertaining to Youngguksa Temple are being excavated, but none described precisely the construction date of the present Daewoongjeon Hall. Also, from beneath the Daewoongjeon Hall, cornerstone and foundation of previous building and several charred wood elements were excavated. In comparing the direction of the stone columns of foundation of the previous structure and the existing Daewoongjeon Hall, the previous structure was rotated in an angle of approximately $15^{\circ}$. Therefore, in order to find the association of the previous structure with the present Daewoongjeon Hall, tree-ring dating was conducted. The dating of 41 original timbers and 14 roof-filling timbers of the present construction elements revealed that the last annual ring was of A. D. 1703 with complete latewood, indicating that those woods was cut some time between the autumn of 1703 and spring of 1704, and the building was erected in 1704 when we assume no period of wood storage. The year of the last annual ring of the charred elements, which were excavated from beneath the Daewoongjeon Hall, was analyzed as 1674. The cutting year of the woods used for the present building began in 1698, therefore, it can be presumed that the Daewoongjeon Hall before the fire was a structure that was elected shortly after 1674 and that a catastrophic fire occurred some time between 1674 and 1698.

  • This study was carried out to identify wood species excavated at the temple site of Backjae dynasty in Neungsanri, Buyeo. At the temple site, there were great excavations such as Backjae Incense Burner(National Treasure No.287) and Stone Reliquary(National Treasure No.288). The King Chang 13 Year carved on Stone Reliquary indicated that this temple was completed in A.D 567. Identification of wood species were as follows: The Temple building was constructed by Pinus densiflora Sieb. et Zucc. The species of the main pillar of Wooden Pagoda which preserved relics of the Buddha was Zelkova serrate Makino.

  • The study was carried out to analyze wood quality of coffin board, the wood species of coffin excavated in Youngdong, Korea. All coffin woods were identified as hard pines, Korean red pine(Pinus densiflora S. & Z.). According to wood quality of coffins, inner coffins of Bae Cheon-Jo and his wife showed similarity and dissimilarity comparing with several literatures. The similarity was in the structure of panels, bottom lining board and charcoal layer, and the dissimilarity was in jointing. From the analysis of fibrous materials attached to coffin woods, the paper mulberry and cotton fibers were identified. In the inner coffin of Bae Cheon-Jo, tool traces by handle planer were observed.

  • Wood identification was conducted for the 8 Neolithic charcoals excavated at Giheung Nongseori Ruins through scanning electron microscopy. They were all identified as hardwood: 6 and 1 were found to be Prinus section and Cerris section of subgenus Lepidobalanus under genus Quercus, respectively, and the remaining 1 to be genus Betula. This species composition was thought to indicate the temperate to warm temperate climate region.

  • This study was carried out to Identify wood and charcoal segments, which were excavated in 1994 at the Seohaean highway construction site along the western coast of Korea ; Tuntaeri, Hwasunggun. We identified the objects excavated at the fire places of the Tuntaeri dwelling sites (early Koryo period ; A. D. $11\~12C$) ; charcoal pieces and 1 wood segment, which was used for the handle of a metal hook. Chestnut(Castanea crenata), deciduous oaks(Quercus spp.) and maple(Acer app.) were identified from the charcoals, whereas the wood segment as willow species(Salix spp.). These species seem to represent warm and wet climate in the middlewest Korea during $11\~12C$.

  • The purpose of this study is to reveal the wood joinery technique in the ancient era. Joinery is one of the core techniques in constructing timber frame architecture in the Korean peninsula. These techniques can be revealed by examining wooden members of ancient buildings. The members were excavated at the Donggung Palace and Wolji Pond, the historic site in Gyeongju. This study collects the data of 284 members excavated at the Donggung Palace and Wolji Pond and analyzes the details such as length, thickness, width, joint types, joint shapes. With the result of the analysis, this study tries to indicate the level of wood joinery techniques in ancient buildings.

  • It was estimated that the Imdang-dong site of Gyungsan was constructed in the 2nd to 4th century based on excavated layers and artifacts. This study was carried out to verify the result using the dendrochronological analysis of six wooden pillars excavated at the site. As a result, it was proven that 6 specimens were not cut at the same age because their tree-ring chronologies were not synchronized each other. And more, it was reconfirmed in wiggle matching dating as confirming two of them were dated to A.D. 94-135 and A.D. 224-289, respectively. It was coincided with the above-mentioned estimated age. In wood identification, most of them were identified as Hovenia dulcis Thunb., Tilia spp., Ulmus spp. which grow usually under cool environment. Based on the result, we could conclude that the climate at that time was cooler than the present.

  • Three wood coffins of Chosun Dynasty period buried about 450 years ago were excavated in the sound condition in Andong area in the early 1998. The proprietors of wood coffins were grandparents, Mr. Myoung Jong Lee and Mrs. Mun, and their grandson, Mr. Eung Tae Lee, and the social standing of their family was known to belong to the nobility in those days by the clan genealogy. All the wood coffins investigated through light microscopy had same anatomical characteristics as follows: abrupt to somewhat abrupt tracheid transition from earlywood to latewood; normal longitudinal and horizontal resin canals with thin-walled epithelium; tylosoids in resin canals; bordered pits frequently in 1 row on radial walls of tracheids; 1 or 2 window-like pits per cross-field; uniseriate and fusiform rays; heterogeneous rays composed of body ray parenchyma cells and marginal ray tracheids or homgeneous rays composed of only ray tracheids; dentate ray tracheids; occasional trabeculae traversing tracheids in radial direction. Based on theses microscopic characteristics, all the wood coffins were identified to be Korean red pine (Pinus densiflora) or Korean black pine (Pinus thunbergii). Korean black pine growing naturally in coastal area might not be probable because the site of excavation, Andong area, was mountainous and inland area of Korea Thus, Korean red pine was thought to be the possible species for the wood coffins because of its natural distribution through the Korean Peninsula and the easy availability.

  • Elemental analysis, SEM-EDX, X-ray diffraction (XRD) and IR analysis were adopted to examine the quality of charred woods excavated from the underground of the Daewoongjeon Hall of Youngguksa Temple, Youngdong-gun, Chungbuk, Korea. A large amount of calcium was detected in SEM-EDX analysis. The analyses of chemical elements suggested that completely charred wood was carbonized at about $500^{\circ}C$. The XRD results indicated the destruction of cellulose crystalline region. The IR analysis exhibited that thermal degradation of wood component was different depending upon the carbonization temperature. It can be suggested from the results that PEG with different molecular weights should be used for the conservation of excavated charred woods.
