본 고는 매우 복잡 다양하게 출토되고 있는 선사시대 토기 중 굽다리토기에 대한 연구이다. 특수한 기형의 이 토기는 분류조차 제대로 이루어지지 않은 채 의례용으로 인식되어져 왔으며, 그 명칭 또한 무분별하게 사용되어져 왔다. 따라서 충분히 객관적이고도 적절한 정립이 필요한 상황이다. 이 토기는 저부와 신부의 상대크기에 따라 대부형(Ⅰ형)과 대각형(Ⅱ)으로의 세부기종 설정이 가능하고 세부기종별 속성분석을 통하여 6형식의 형식분류가 이루어졌다. 무문토기시대 전기 주거지유적에서 공렬 및 각형토기와 공반하는 1·2·3·4형식의 토기(북한→강원영동→경기중부·충청서해안지역)는 점토대토기문화가 도래하면서 생활, 분묘, 생산, 폐기 그리고 의례관련유구에서 출토되는 5·6형식 토기(경기중부·충청서해안→호남·영남지역)로의 변화를 보이면서 전개된다. 즉 점토대토기문화가 도래하는 시점에서 굽다리토기의 형식도 변화·확대되고 있다. 또한 출토맥락, 형식조합, 제작기술 등의 관점에서 공렬 및 각형토기와 공반하는 1·2·3·4형식은 일상 생활용기로의 상정이 가능한 반면 점토대토기와 조합을 이루는 5·6형식 토기는 의례관련유구와 분묘유구에서 다량 출토되고 있어 기원이나 소원과 관련된 의례용기, 그리고 부장용으로의 기능분화가 관찰된다. 〔주제어〕: 굽다리토기, 공렬토기, 각형토기, 점토대토기문화, 기술유형, 시공적 전개, 기능분화

In order to understand affinities and phylogeny of three families of the Superfamily Entomobryoidea allozyme analysis was performed with three species presumably representing each family, in addition to four species belonging to the neighboring Superfamily Poduroidea together. Electrophoresis for this purpose produced data for calculating allele frequency and enabled to obtain genetic distance and to depict dendrograms as well. The species of Isotomidae, Entomobryidae and Tomoceridae were clustered together whereas those of Hypogastruridae, Onychiuridae and Neanuridae were grouped as monophylies, respectively. Even though Tomoceridae and Entomobryidae were brought together they are considered complete families by showing high genetic distance value between them, thus supporting the hypothesis on their affinity among others. Gulgastrura reticulosa has been revealed to be separated from Hypogastruridae by being clustered rather with Onychiuridae. However, its high genetic distance value suggests the status as an independent family. The present result agreed with the phylogeny of Suborder Arthropleona divided into two Superfamilies mentioned above as in conventional systematics and also when compared with analysis of data of their morphological characters as well as 18S rDNA performed and published elsewhere by the present writers.

This study focused on making technique and usage of potteries from Proto-Three Kingdom to Baekje Kingdom in Balanri Site. The potteries were divided into four groups, Jungdo type I, Jungdo type II, Tanalanmun type and the Baekje type on the basis of the shape and physical properties. The Jungdo type potteries were used as kitchen wares, showing mostly yellowish brown color. The Tanalanmun type potteries were used as storages, showing gray green color. Firing temperature of the Jungdo type and the Baekje type potteries were presumed to be fired at 900 to $940^{\circ}C$, whereas the Tanalmun type potteries were fired at around 900 to $1,100^{\circ}C$. This is indicated that the firing condition was adjusted according to the purposes of the potteries. On the one hand, the Balanri potteries were made of paleo-soil which was collected in very near place from the site based on geochemical characteristics of the pottery clays and the soil.

In this study, we aimed to elucidate the materialistic characteristics of 11 pieces of earthenware belonging to the Neolithic and Bronze Age excavated from Jeongseon Auraji, South Korea. As a result, the chemical composition of earthenwares belonging to the early Bronze Age was distributed in the intermediate area between the Neolithic and Bronze Age earthenwares, but no significant difference was confirmed based on their manufacturing period. Upon comparison, the earthenwares excavated from Jeongseon Auraji site were found to comprise less acidic components than those excavated from Yeongdong, and are characterized by the alkaline components depending on the excavated site. In the rare earth elements distribution pattern, all the analyzed earthenwares exhibited similar pattern, confirming that the raw materials present in the clay were the same. As a result of microstructure analysis, the clay particles and voids were found to be irregularly distributed in the analyzed earthenwares. Neolithic earthenwares exhibited many irregular voids, and an arrangement of aluminosilicate, including feldspar, was observed along with the clay substrate. Furthermore, we confirmed that the empty space in early Bronze Age earthenwares was filled with fine particles and cube crystals. Moreover, the main mineral phase of earthenwares excavated from Jeongseon Auraji exhibited similar composition, and therefore, there was no significant difference in the firing temperature of these earthenwares. The firing temperature of the earthenwares ranged from 750 to 850℃.

This study investigated potential damages and conservation methods for the ceramics (without glaze) by examination of physical and chemical effects from the burial environments. For this study, pottery samples excavated from Daejeon Hakha, Asan Eumbong, Hwasung Sogeunsan and Kongju Haengbokdosi were examined with released ions and extraction through desalination. The result showed that the ion inflow into the ceramics was dependent upon the porosity and the absorption of ceramics. The high temperature fired ceramics (over $1,000^{\circ}C$) have low porosity and absorption, therefore almost no salt infiltration during the burial period. However, low temperature fired ceramics (under $800^{\circ}C$) have high porosity and absorption, and most of salts were removed during the desalination. The 40 to 60% of salts were removed in two days and 60 to 80% of slats were released in a week. Furthermore, fertilizer residues such as $K_2SO_4$, in soils were detected in the ceramcis. Also the characteristics of buried soil affected ion infiltration into ceramics. Ceramics buried in sandy soil had relatively less ion contents from buried environments than those in clayey soil. Therefore, low temperature fired ceramics could do not only cleaning but also desalination if it is necessary, and the period could be decided to the condition of ceramics.

This study focuses on the understanding of human subsistence and pottery use during ancient times on the Korean peninsula through lipid analysis of potsherds from several major prehistoric settlement sites. Ancient human subsistence has been one of the long-standing topics in Korean archaeology. However, since the high acidity of sediments does not allow long-term preservation of organic remains, we still lack some critical information related to the prehistoric diet. Pottery contains relatively well-preserved organic remains created during past cooking events. Though pottery is one of the most studied material cultures in Korean archaeology, almost no attention has been given to analyzing the pottery itself. This is a surprising omission and represents a serious gap in our understanding of prehistoric technology and subsistence. The analysis of ancient lipids extracted from the pottery matrix using GC-MS and isotope analysis can contribute to our understanding of the true nature of past subsistence strategies. Potsherd samples for the analyses in this study were collected from six prehistoric and early historic settlement sites located in the central part of the Korean peninsula. The results showed that subsistence strategies differed by both location and time period. For example, at Jungdo, an inland open-air Bronze Age settlement site in Chuncheon City, we were able to see the presence of terrestrial mammals. At Gahak-dong, Gwangmyeong City, marine resources were utilized, as the location of the site is not far from the coastline. At the early historic site of Guwol-dong, Incheon City, we were able to detect dairy products. The results of this study suggest that there was utilization of a wider range of resources among ancient dwellers in the central part of the Korean peninsula.

The studies of non-figure plain coarse pottery from Jeju island is very important because it can explain the characters of plain coarse potteries of the bronze age and the early iron age. In this study, We analyzed the non-figure plain coarse popery from Jeju island in two ways. One is analysis of the chemical composition using X-ray fluorescence spectrometer and X-ray diffraction, the other is analysts of clay mineral contained iron, oxidized iron's genus, valence state and magnetic properties using Mossbauer spectroscopy. We confidence that non-figure plain coarse pottery is chiefly made of silicate minerals, like SiO$_2$. The content of noncrystalline ferrihydrite is supposed to be below 5-10 wt%, non-figure plain coarse pottery is considered to partly consist of Jeju island clay, which is made of neutral volcanic rock and the valence state of iron is Fe$\^$2+/ and Fe$\^$3+/. We presume the reason that the magnetic hyperfine field is lower than that of pure goethite is the change of crystal structure which transforms the combination states of Fe ions while the clay is being fired.
