The objective of this study was to date coffin woods of a grave of husband and wife, using the tree rings, which were excavated from Hoamdong, Chungju city in the central area of South Korea. The species of coffin woods was Japanese Red Pine (Pinus densiflora S. et Z.), one of the major conifers growing in Korea. The husband coffin was dated as A.D. 1628. Due to the absence of bark in the wife's coffin, the number of sapwood rings was estimated to obtain the cutting date. The cutting date of wife's one was estimated to be A.D. 1651${\pm}$10. The Jeogori Jacket for women, which was found in the husband coffin, indicates that the husband died earlier than the wife, as the tree-ring dates suggested.

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.

전주 마전 유적에서 출토된 회곽묘 1기에 사용된 목재의 수종 식별과 연륜연대 분석을 하였다. 수종 식별 결과, 관재는 모두 소나무속중 소나무류 (적송류)로 동정되었다. 7개의 관재로부터 총 24점의 관편에 대한 연륜연대 분석결과, 6개에 대한 연대를 부여할 수 있었다. 횡대에 쓰인 관재는 수피를 그대로 간직하고 있고 마지막 나이테가 만재까지 완전히 형성되어 있어 1637년 가을에서 1638년 봄 사이에 벌채된 목재로 관을 제작하였음을 알 수 있었다. 다만 벌채후 건조, 저장 기간으로 인하여 연륜연대와 관의 제작 및 매장 연도와는 다소 차이가 있을 수 있다.

This work aims to investigate on the low cycle fatigue life assessment, which is adopted on the strain-life relationship, or better known as the Coffin-Manson relationship, and also the strain energy density-based model. The low cycle fatigue test results of Alloy 617 weldments under $900^{\circ}C$ have been statistically estimated through the Coffin-Manson relationship according to the provided strain profile. In addition, the strain energy density-based model is proposed to represent the energy dissipated per cycle as fatigue damage parameter. Based on the results, Alloy 617 weldments followed the Coffin-Manson relationship and strain energy density-based model well, and they were compatible with the experimental data. The predicted lives based on these two proposed models were examined with the experimental data to select a proper life prediction parameter.

The purpose of this study was to identify the species of coffin woods excavated at Mundangdong in Gimcheon and to date this coffin by using tree-ring method. All coffin woods were identified as red pines, most possibly, Pinus densiflora S. et Z. Tree-ring dating provided absolute years of 3 among 19 coffins. Both I-9 and II-22 coffins were estimated to be made in the mid-seventeenth century, and I-65-1 in the mid-sixteenth century. Others possessed too few rings to be dated.

In the conservation treatment of wood remains, polymers, treatment methods, and treatment period can be varied, depending on the percentage of moisture content and species of trees. Thus, in order to apply the appropriate conservation treatment, a lot of information from the wood remains are required. Despite the information from the wood remains, testing a part of the wood remains is necessary to get information about the polymers. When the wooden coffin made of camphor trees was excavated, it was cracked in the section of radiation, and there were hairlines cracks. Therefore, without any conservation treatment, it is impossible to restore it. This experiment is for the conservation treatment of the wooden coffin excavated from Songhyun-dong tombs No 7, Changnyeong. For this experiment, I used camphor trees from Jejudo. The purpose of this experiment is to asses the possibility of preliminary testing materials before the conservation treatment on the wooden coffin. After the camphor trees from Jejudo are artificially aged by Fenton's reagent, they are As a result of oxidation by Fenton, the degree of oxidation is high in proportion to the amount of peroxide and iron sulfate. Among several samples, the sample 'na' made the most similar result to the wooden coffin from Songhyun-dong. If I use this condition to make the sample in polymer tests, it is very helpful to find the most suitable polymer for the conservation treatment of wooden coffin. After the same species of trees are oxidized by Fenton and they become the similar condition, we are able to find suitable methods of conservation treatment. The suitable methods reduce the demage of the remains and make us to get more information. Thus, we are able to carry out conservation treatment more exactly.

We have used the Naju Oryang-dong Kiln, the Jar coffin producing center from the 5th to early 6th century A.D. found for the first time in Korea in 2002 and conducted trace element analysis of Jar coffin objects excavated in Jar coffin the old tomb area formed mainly around Yeongsan valley, the consuming area of the same period as our main research objects. For this analysis, we have used both the NAA method, the non-parametric micro-minerals analysis. In order to compare and verify these remains, we have used the results from the analysis on the Jar coffin remains in the Mandong remains, Jeonbuk district. We have quantitatively analyzed 17 types of elements from the Jar coffin remains sample to allow for various and correct analysis. With their results, we could find out that the jar coffins made in Oryang-dong kiln teo are statistically identical to those in Daean-ri Old tomb/Shinchon-ri 9th old tomb, Okya-ri old tomb, and Banam-Old tomb. Also, we can conclude that there is a high possibility that ongwans produced from Oryang-dong kiln being used in Daean-ri Old tomb/Shinchon-ri 9th old tomb, Okya-ri old tomb, and Banam-Old tomb was distributed through some form of trade. On the other hand, we could obtain other analysis results that jar coffins excavated and investigated in the Mandong remains and Ithe npyong Old tomb were likely from other Jar coffin kilns through trade and distribution.

순창 농소고분은 적성면 운림리 일대와 내월리 농소마을을 둘러 형성된 구릉지 능선에 위치하고 있다. 고분의 토광은 비교적 깊은 곳에 조성되어 도굴의 피해가 없었으며 전체적으로 다량의 숯으로 채워져 있어 목관이 비교적 좋은 상태로 출토되었다. 고분 구조 및 매장시설, 출토 유물, 방사선탄소연대 측정 결과를 종합하였을 때 농소 고분의 축조시기는 고려시대 후기부터 조선 초기까지로 추정하고 있다. 농소고분에서 출토된 목관은 목곽과 목관의 2중 구조로 목관 외면에 두껍게 옻칠을 하고 금색 문자와 흰색 문양으로 장식되었다. 안료 분석 결과 금색 문자는 금(Au), 흰색 문양은 은(Ag)이 주요 성분으로 확인되었다. 칠 막은 안료 층, 황갈색 층, 검은 층의 3개 층으로 관찰되었다. 검은 층은 그을음과 같은 검은 물질로 목재 바탕의 밑칠로 사용되었다. 황갈색 층은 옻칠로서 정제칠로 추정된다. 목관 칠막 분석을 종합하면 칠 제작방법은 금박을 이용하는 방법과 금분을 이용하는 방법으로 추정된다. 안료 형태 및 내부 구조상으로는 금박이 유력하지만 표현된 글자의 형태를 보면 금분을 이용한 것으로 보인다. 따라서 향후 금박과 금분을 이용한 재현실험을 통하여 제작방법을 확인한다면 고분 축조 당시 칠기 제작기술을 파악하는데 중요한 자료가 될 것이다.

The burial custom in the Youngsan river area was to build a jar-coffin and lay the body in state, however the methods in building and moulding the massive jar, as well as in which kiln it was made has not been examined precisely. Thus, this research not only investigates previous results related to the manufacturing methods of massive jar-coffins, but also examines samples that were excavated and collected. The clay used to produce jar-coffin consists a large portion of unglazed qualities, which was split-moulded from the bottom up to the mouth area. The interior was finished by applying water, whereas the exterior was decorated by regularly pasting or stamping in parallel with a lattice design. It can be presumed that the finished jar-coffin was not moved, but the ceiling and walls were built around it as a kiln, for the jar-coffin to be oxidized or to reduce the flame condition in a temperature approximately $700~1,200^{\circ}C$The results from the research, however, show limitations to exploit the exact manufacturing method, therefore there is a need for in-depth examinations: mineralogical investigation on a large amount of jar-coffin samples through a polarized light microscope; substance analysis using various equipments; speculation on the temperature in the place of production and the flame inside.
