The Chungdo-type Pottery Culture, distributed through the middle part of the Korean peninsula, is chronologically located in the very former stage of the advent of ancient states. It has two different traditions of pottery manufacturing technique which are totally different in choosing raw materials, shaping, fixing and firing. It seems that two different traditions had been selectively applied by pottery type. In order to understand this peculiar cultural aspect, the pottery typology needs to be different from those applied to cultures where pottery was made and used under the single manufacturing tradition. This study tries to find the new pottery typology which best fits for the understanding the chronology of the Chungdo-Type Pottery Culture. For this purpose, I examined existing typologies, recognized their problems, and then build a new typology. As a result, I found that the former typologies misinterpreted the relative frequencies of each pottery type as different function or region. In this article, I propose the new pottery typology as building a primary classification within each function and region, and then synthesizing all of primary classifications. This new typology eliminates the factors of function and region in understanding the chronology of the Chungdo-Type Pottery Culture, and assorts the regional distinction by comparing pottery types in each region.

Terrestrial magnetism has left traces through residues such as fossils of the terrestrial magnetism as time went by. An analysis of archaeological terrestrial magnetism is an estimation of dates of archaeological remains where baked earth is exposed by measuring the change of the past terrestrial magnetism through thermo-remnant magnetization of baked earth. This paper attempts to apply an analysis of the archaeological terrestrial magnetism to archaeological remains using fourteen soil samples extracted from a charcoal kiln with side window located at the Area Ⅰ of Maegokdong. The date of A.D.440${\pm}$15 the analysis of archaeological terrestrial magnetism came up with gives solid evidence, while an archeological chronicle used arrangements of surrounding artifacts because of the absence of remains and assumed uncertainly that a charcoal kiln with side window was from the three kingdom periods. This analysis of archaeological terrestrial magnetism has come to anchor as a main natural scientific analysis because it relatively easily removes pollutants and comes up with highly reliable results owing to its considerably narrow error tolerance of assumed dates.

The purpose of this study was to analyze radiocarbon dating, using wiggle match, of a wooden board from Yeongheung-do shipwreck excavated from Yeongheung-do in Incheon Ongjingun. The result of wiggle matching for 5 decennial tree-ring block samples of the hull bottom board produced ${\pm}2{\sigma}$ radiocarbon date (95.4% confidence interval) as A.D. 710~730 or A.D. 750~774. It indicated that the Yeongheung-do shipwreck belonged to the early or middle of the 8th century. Radiocarbon dating results confirmed the date speculated by archaeologists according to ship structure and pottery style.

Tree-ring chronologies can be used to date historical buildings or furnitures by matching them with chronologies of living trees. Tree-ring dating gives a calendar year to each tree ring and produces the cutting dates of logs or woods. In this study, we intend to extend our tree-ring dating applications to Korean furnitures. As a case study, we examined two traditional furnitures, one cabinet 'Jang' and the other chest, 'Bandaji'. The cutting date of the cabinet woods was A.D. 1839. The date of the outmost ring in the chest was A.D. 1904. Due to no bark present, the cutting date of the chest was only estimated as $1930{\pm}10$ by 'sapwood rings' estimation method. Ring-width pattern of the latter one also indicated that the origin of the chest must be Kangwon province. This case study suggests that tree-ring dating would be a useful and accurate method to identify the critical dates for the chronicles of Korean traditional furnitures.

The physical and chemical characteristics of loess-paleosol sequence in Jeongjang-ri, Geochang basin are examined using the magnetic susceptibility measurement, grain size analysis, OSL age dating, major, rare earth and trace elements analysis. The grain size characteristics of the loess-palesol sequence are obviously different from those of river sediment forming river terrace deposits and the Chinese Loess Plateau. The loess-paleosol sequence consisting of L1, L1LL1, L1S1, L1L2, S1 and L2 from top to bottom is estimated to MIS 2~MIS 6 and the river terrace to MIS 7. The compositions of major, rare earth and trace elements indicate that the sequence show more weathered characteristics than the Chinese Loess Plateau and originated from the Chinese Loess Plateau. These features are in harmony with the previous studies in Korea.

The wooden pagoda sites which have been confirmed in Baekjae's former territory so far have flattened surface of the earth or foundation pert made by digging up the earth. In particular, the latter is found more often in the pagoda sites of Baekjae, which is essential and absolutely necessary because of the characteristics of pagoda structure. The wooden pagoda sites with foundation part made by digging up the earth under the stylobate are found at Yongjeongli ruined temple site of Woongjin area, and at Neung-sa temple site, Wangheung-sa temple site, Geumgang-sa temple site, and Mireuk-sa temple site of Sabi period. They are also observed at Hwanglyong-sa nine-storied wooden pagoda of Shilla and at Biin five-storied stone pagoda of early Goryeo. They are important data improving that the construction technologies of Baekjae continued to be applied to build stone or wooden pagodas, transcending time and space. Recently, the site assumed as a wood pagoda site of Hanseong area was examined in Gyeongdang sect ion of Pungnap mud fortification. If this is proved to be a real wooden pagoda site, this digging-up construction technology of foundation part ann be concluded to be a traditional engineering technology of Baekjae which was frequently used from Hanseong period to Sabi period. On the other hand, this digging-up construction technology of foundation part has been found only at pagoda sites and main building sites of temple ruins, and it helps examine their symbolism.

필자는 이 글을 통해 제주도 고고학 발달사를 크게 4기로 구분하여 보았다. 제1기는 1945년 이전 일제강점기에 유적과 유물을 단순하게 보고하는 수준에 머물렀던 시기이고 제2기는 1945년에서 1983년 기간으로 향토사가와 한국 본토의 고고$\cdot$역사학자들의 부분적인 학술조사가 있었던 시기이다. 따라서 1$\~$2기는 제주 고고학의 기본적인 틀을 잡지 못한 단계라고 할 수 있다. 제3기는 1984년부터 1995년까지로 제주고고학에 있어 본격적인 발굴이 진행되지만 대부분이 긴급 발굴에 해당하고 소규모적인 발굴이었다. 하지만 이 시기에 와서 그 동안 발굴했던 자료와 그 이전의 발굴자료를 모아 나름대로 제주고고학의 시대 편년, 문화 변천 등의 기본적인 틀과 방향을 설정한 시기이기도 하다. 제4기는 1996년 이후 현재까지로 제주고고학의 기본적인 틀 속에서 이를 보완하고 새로운 선사문화의 단계를 설정하는 연구들이 진행 중이다. 이를 뒷받침하는 계기는 제주 고산리유적, 삼양동유적 등이 연차적, 계획적, 대대적으로 발굴되면서 많은 자료가 나왔기 때문이다. 또한 고고학의 범위가 선사시대에 국한되지 않고 제주목관아지, 성읍객사지, 법화사지, 존자암지, 수정사지, 고내현청터 등 역사유적의 출토자료에 대한 관심이 더욱 집중되기에 이르렀다. 제주도내 매장문화재는 발굴된 유적 대부분이 지정되어 있는 상태이다. 제주목관아지(사적 390호), 항파두리성(사적 396호), 고산리유적(사적 412호), 삼양동유적(사적 416호)로 지정되었다. 제주도 지석묘는 총 24기가 지방기념물로 지정되어 있으며 발굴했던 선사유적 중 곽지패총, 북촌리바위그늘집자리, 용담동무덤유적이 지정되어 있다. 역사유적 중 법화사지, 존자암지가 지정되었고 일부 유적지는 복원 중이다. 제주도 문화재를 보존하고 활용하기 위해서는 강화된 새로운 문화재법의 적절한 활용, 매장문화재 발굴 전문기관 설립, 발굴된 문화재의 원상보존, 문화재 주소록 작성, 문화재 행정 전문인력의 확보, 제주문화재의 상징물 선정과 활용, 지역문화재홍보위원의 위촉과 다양한 문화유산 프로그램의 개발을 들었다.

This study examines the ratio of alloy components of six gold crowns discovered in six Silla tombs; Gyo-dong, the north tomb of Hwangnamdaechong, Geumgwanchong, Cheonmachong, Geumnyeongchong and Seobongchong. Concretely, the study looks at whether and how crowns from these various tombs differ in terms of the ratio of alloy components. The analysis of the six Silla crowns found that all of them were made of gold and silver alloy. When comparing the ratio of alloy components in crowns and type of crowns, the Gyo-dong crown which is the oldest of them showed the highest content of gold. Crowns from Hwangnamdaechong and Geumgwanchong in the middle to late 5th century, showed a similar content of gold. Gold content of crowns from the late 5th century to early 6th century tombs decreased in order Cheonmachong, Geumnyeongchong and Seobongchong, thus it confirmed that the older the tomb, the higher its gold content.

The purpose of this study was to carry out radiocarbon dating using a wiggle match, of wooden boards and grains from the Mado shipwreck No. 4, which was excavated from Mado in Taean-gun, Chungcheongnam-do. The result of the wiggle matching for four decennial tree-ring samples of the stern plank produced a ${\pm}2{\sigma}$ radiocarbon date (95.4% confidence interval) of A.D. 1337-1356 or A.D. 1412-1429. The grains produced a ${\pm}2{\sigma}$ radiocarbon date (95.4% confidence interval) of A.D. 1415-1455. This indicated that the Mado shipwreck No. 4 belonged to the early or middle of the 15th century. These radiocarbon dating results correlate with the date that was speculated by archaeologists according to the ship's structure and ceramic style.
