A lot of relics were unearthed in the Shinchang-dong wetland site, which can help restore prehistoric life style, including construction tools such as wood doors, wood hammers, ax handgrips, sickle handgrips, wedges, awls, wood pillars and connection members, food vessels made of earth or wood and fish, shell fish, seeds and remains of weapons. In particular, a door was found in the site, which was measured at 110cm long and 37cm wide. If restored it will be 75cm wide. The door seems to date back as far as the 1st century B. C., which would be the oldest one ever discovered in Korea. This paper is intended to explore the implications of the door by investigating the environment of the Shinchang-dong wetland site bearing the relics intact, manufacturing techniques and times of manufacturing of the door as well as attributes of doors presented in the literature related to old time architecture such as Goguryeo tomb paintings and house-shaped vessels. It also intends to provide basic data for study of residential architecture in prehistoric times.

Tripitaka Koreana were made during Coryo Dynasty from 1236 to 1251 A.D. Buddhist scriptures were engraved on 81.340 wooden plates. Some plates were varnished with Rhus lacquer, but most of them were uncoated. Macroscopically, most of the plates appeared intact due to the storage in a well-ventilated wooden house. Because, they were irregularly used for printings with ink, it can be assumed that they were repeatedly exposed to ink-water and drying processes. The present were made to examine the changes of wood cell structures occurred during long-term aging deterioration processes in these dry archaeological wooden plates. Light, scanning and transmission electron microscopes were employed for this study. Wedge-shaped cracks and delamilations were found from the lumen side toward the compound middle lamellae and they progressed toward primary or secondary walls. A large amount of hypae in vessels and the degradation of vessel-ray pit walls by the fungal hyphae were observed. When compared to the recent wood, the birefringence of wood fibers was considerably lower or completly disappeared, suggesting the degradation of crystalline cellulose in these wood samples. The degradation of the cell wall could be also revealed the calculation of crystallinity with X-ray diffraction and the size of crystalline region was estimated.

The purpose of this study is to analyze the architectural character of the upper risen architecture(高床式 建築) in Japan. There are few upper risen architecture and architectural remains in Korea. Until now most of Korean researcher recognized that the upper risen architecture is southern regions' form. But there are a few numbers of upper risen buildings in northern regions of Korea and China. Therefore we need to compare northern and southern regions' upper risen architecture. The scope of this study is architectural remains, sites and present buildings about upper risen architecture in Japan. The period of this study is from third to eighth century. The method of this study is the analyses of site plan(the ratio of front and side length) and construction about Japanese Architecture. And then this study compare Japanese with other countries in Korean and Chinese upper risen architecture. Results of the study are below. 1. In Japan, upper risen architecture was introduced into southern regions(southern China and southeast Asia) with rice farming culture. 2. After introduced upper risen architecture, they were influenced many architectural technique of Korean and Chinese. 3. There were many technical improvement(such as foundation stone standing method, high technical wooden frame structure and adaptable triangle frame wall at moisture) the Japanese upper risen architecture in Nara Period(奈良時代). 4. As the results, I found out that there were many similarity Korea and Japan in upper risen architecture. I think that we will try continuous to study another regions' upper risen architecture in order to define conclusion.
