Fifty ancient Korean coins originated in Choson dynasty have been determined for 9 elements such as Sn, Fe, As, Ag, Co, Sb, Ir, Ru and Ni by instrumental neutron activation analysis and for 3 elements such as Cu, Pb, and Zn by atomicalsorption spectrometry. Bronze coins originated in early days of the dynasty contain as major constituents Cu, Pb and Sn approximately in the ratio 90 : 4 : 3, where as, those in latter days contain in the ratio 7 : 2 : 0. Brass coins which had begun in 17century contain as major constituents Cu, Zn and Pb approximately in the ratio 7 : 1: 1. The multivariate date have been analyzed for the relation among elemental contents through the variance-covariance matrix. The data have been fur theranalyzed by a principal component mapping method. As the results training set of 8class have been chosen, based on the spread of sample points in an eigenvector plotand archaeolgical data such as age and the office of minting.

This study aims at examinating the change of architectural technique in the residential district of Seoktanri(石灘里), and then extracting the restorable types from it. The constructive technique was advanced in the composition of walls and the use of footing. The arrangement of columns was developed to standing them in a row and three rows in the center of interior space. In the light of excavated relics and the position of furnace, the interior space is seperated into cooking-heating, working and storing space. By the difference of height and the slope, the floor is divided into two parts which are low and high. According to the arrangement of column-holes, the types of roofs to be restored are as follows; the gable roof without column-hole, the hipped roof with center-column-holes(中央柱孔) in a row and the gable roof with center-column-holes in three rows.

Understanding the variability of the monsoon system requires information about the changes in the past. We revealed the Mid- and Late-Holocene paleo-climate changes and Asian monsoon variations in Korea by the speleothem records from Pyeongchang. To this, we used thicknesses of growth laminae, stable-isotope analysis (carbon, oxygen), and radio-carbon age dating. The speleothem grew between ~4580 yr BP to ~660 yr BP and we identified several weak AM(Asian monsoon) events, such as Middle Bronze Age Cold Epoch, Iron Age Cold Epoch, and Dark Age Cold Period. These events might have occurred relatively early compared to those of other studies.

Although the bottle gourd (Lagenaria siceraria) is a crop with a cultivation history of about 10,000 years in the Old and New Worlds, archaeological considerations on the cultivation and use of bottle gourds on the Korean Peninsula are extremely rare. Accordingly, we reviewed previous reports on bottle gourds and examined the morphological characteristics of seeds and rind fragments from the Korean Peninsula. The investigation yielded several conclusions. First, bottle gourd cultivation likely began during the Bronze Age alongside the introduction of so-called southern crops. Evidence suggests that bottle gourd remains were more prevalent during the Three-Kingdoms period, indicating its significance as a crop during the historical era. Second, bottle gourd seeds from the Three-Kingdoms period exhibit characteristics of both African and Asian subspecies, showcasing a high level of morphological diversity. Third, rind thickness indicates that bottle gourds found at the Bongseon-ri site were of varieties with large fruits. Taken together, it is concluded that the bottle gourd was introduced to the Korean Peninsula during the Bronze Age, and people cultivated a range of bottle gourd varieties during the Three-Kingdoms period.

In order to understand the local vegetation history and the origin of rice cultivation, a phytoliths analysis was performed with sediments collected from archaeological site at Ga-dong in Gijang, Busan. From the analysis with the sediments of three sampling sites, fan-shape phytoliths of Oryza sativa were detected: sediment 8 ~ sediment 29 of sampling site 1, sediment 6 ~ sediment 20 of sampling site 2 and sediment 7 ~ sediment 33 of sampling site 3. On the bottom layers or near the bottom layers from the three sampling sites, high densities of Arundinoideae and Andropogoneae were detected. It indicates that these layers were wet soil environment when they were sedimented. From near bottoms up to surfaces, the densities of Arundinoideae and Andropogoneae were abruptly decreased, while the density of Oryza sativa was sharply increased. With these results, it should be considered that the rice cultivation was started from the Bronze Age on this region.

There is no definite theory, which archeologists have believed to be built either for the protection or ceremonial purpose, of enclosure historical site exhibited from Bronze Age to Samhan era in Korea. The main conditions of choosing right enclosure were natural levee-backswamp-plateau, which all found in village on a hill. For this reasons Kimhae Daesoeng-dong enclosure discovered in 2001 is not an exception, and therefore this enclosure has been believed to be a beginning point of the farming society. In Korea there have been 2 types of enclosure. One is that enclosure entirely surrounds whole historic site itself and the other is that enclosure partially does. Although Kimhae Daesoeng-dong historic site has been discovered only part of it, it's not believed to have the first type-which surrounds the whole enclosure historic site In this research, 3 developing steps of enclosure historic site were defined. Enclosure surrounds only a part of the historic site is 1st step. Enclosure surrounds all around the site is 2nd step. The site discovered with big round clay pottery and developed into multiple enclosure is 3rd step. Since some researches have not been accomplished, the hypothesis above was suggested to have a better understanding of the development of enclosure historic site. The purpose of enclosure has been separately explained for the protection or for the ceremony. It is difficult to assert that excavation sites could be applied to only one of two purposes. But it is possible that both purposes of enclosure such as protection and as division from ceremonial area could be applied together. Kimhae Daesoeng-dong enclosure was shown for the purpose of division from ceremonial area. But we can not ignore that since Kimhae Daesoeng-dong enclosure exposed to the Sea and dwelling area was not shown from village hill, it would be probably for the protection. However enclosure of Gujibong village area in Daesoeng-dong had used for ceremonial purpose since the Bronze Age, even this enclosure would be possible to play an important role of being a center of legend of Gaya foundation. Many unsolved questions are still lying ahead. The enclosure was used for a short time, even if dwelling area was found in and out of enclosure, there were no differences between them, and although duplicate and triplicate enclosure were found, we could not sure which were before and after. Also we could not confirm the type of enclosure with location condition which was the flat land or the top of hill on floodplain. We should not divide the types of enclosure historic site due to differences from cross section of stratum. And I expect that we will have much data such as distribution of enclosure historic site in Yeongnam area where is concerned with origin and diffusion of Japan and China.

The aims of this study are to clarify the geomorphological development of a alluvial plain and discuss the vegetation environments and agriculture activities in the Wangpo-River alluvial plain at Neungsan-ri, Buyeo by analyzing geomorphological classification, sedimentary facies and age datings. The alluvial plain at Wangpo-River was formed by the influences of Geum-River with the sea-level rising during the Holocene. The basin of Wangpo-River consists of natural levees, back marsh-type alluvial plains, valley plains and hills. The natural levees by Geum-River largely distributes at the area where Wangpo-River flows to Geum-River and the alluvial plains at the middle and lower reach are the back marsh areas of Geum-River. Moreover, the area along Wangpo-River show higher contents of coarse materials and thinner peat sediments than the back marsh. The lower sandy deposits in the alluvium of Wangpo-River was formed with the influences of human in the Bronze Age during the sea level falling and the peaty deposits was formed due to the water level rising of Wangpo-River during the sea level rising in the early Iron Age.

This paper is aimed to study the late Neolithic Age in North Korea in order to closely examine a transition process into the Bronze Age in the Korean peninsula. Thus, the pottery with lightning design was selected as target data. Since the pottery with lightning design is fundamental data that North Korea's archeologists have used for chronological recordings of the late Neolithic Age in the northwest region, the parallel relationship between the eastern and the western region was established with comparison of pottery with lightning design in the northeastern region. The examination focuses on data that cover the target region of the pottery with lightning design of the adjacent Southern Primorskii region including the counterpart of the northwestern and the northeastern region. As a result, some attribute analyses revealed that the pottery with lightning design was affected by the counterpart of the northwestern region near the Yalu River. Prior to genealogical and chronological recordings of the pottery with lightning design in the northeastern region, the pottery with lightning design in the northwestern region was recorded chronologically in order to examine its specific development process. Consequently, in the second period of the Neolithic Age, the pottery with lightning design in the northwestern region was assumed to have an impact on the counterpart in the northeastern region. The classification of the pottery with lightning design in the northeastern region shall be based on 4-period development. According to this classification, the pottery, which was found in the Tumen river basin, was thought to belong to the first period. The pottery went through genealogy differentiation in the second period and when entering into the third period, the pottery spread to inland of south Primorskii. The pottery was assumed to exist in the southern Primorskii region until the tip end (the fourth period) of the Neolithic Age. It is assumed that considering the fact that climate change led to the agriculture movement, Zaisanovka culture, i.e. the late Ne Neolithic Age, moved to the southern Primorskii region along the Tumen River basin.

The Khogno Khan mountain special protected area belongs to Khogno Khan subdistrict of Gurvanbulag district of Bulgan Province and is 46.9 sq.km. with its main feature being mountain forest zone. In this paper we present some results of research of the Anthropological and archaeological team of Mongolian Korean Joint research expeditions carryied out in Khogno Khan mountain special protected area from 27 July to 1 August, 2000. During archaeological reconnaissance we discovered around 27 localities of archaeological monuments belonging to different historical periods (from the Neolithic up to the Mongolian period, $13^{th}-17^{th}$ Century) in the territory of the Khogno Khan special protected area. Based on the results, we especially want to point out 1). The archaeological and historic monuments (from the Neolithic up to modern era) found in the Khogno Khan mountain and its surrounding area show that since the Neolithic period (around 8000 years ago) this area was occupied by the ancestors of Mongolians and it was used during subsequent historic periods on the one hand. 2). On the other hand the Khogno Khan mountain region was one area where there occurred intensive admixture between populations of Kurgan culture, Deerstone culture from the West Mongolia and the population of slab graves culture from Central and East Mongolia during Bronze and Early Iron Age. 3). Today the mountain is one of the area with a unique assemblage of archaeological monuments from different historic periods, what naturally seems like an open-air natural museum of Mongolian Prehistory.

Some ceramic artifacts representing time-wise from comb pattern pottery in the Neolithic Age to white porcelain in Joseon Dynasty were selected from 7 sites in the north and south area of Charyeong Mountain Range in order to making techniques interpretation and development process of ancient ceramics through physicochemical and mineralogical quantitative analysis. Studied pottery samples in the Prehistoric times showed trace of ring piling in soft-type, and pottery in the Three Kingdoms Period had both soft and hard-type but kettle-ware and storage-ware were made with ring piling, but table-ware was made by wheel spinning. Different from pottery after the Three Kingdom Period when refinement of source clay was high, pottery in the Neolithic Age and in the Bronze Age exhibited highly mineral content in sandy source clay, which showed a lot of larger temper than source clay. Groundmass of celadon and white porcelain almost did not reveal primary minerals but had high content of minerals by high temperature firing. Ceramic samples showed some different in major and minor elements according to sites irrespective of times. Geochemical behaviors are very similar indicating similar basic characteristics of source clay. However, loss-on-ignition showed 0.01 to 12.59wt.% range with a large deviation but it rapidly decreased moving from the Prehistoric times to the Three Kingdom Period. They have correlation with the weight loss due to firings, according to burning degree of source clay and detection of high temperature minerals, estimated firing temperatures are classified into 5 groups. Pottery in the Neolithic Age and in the Bronze Age belongs from 750 to $850^{\circ}C$ group; pottery in the Three Kingdom Period are variously found in 750 to $1,100^{\circ}C$ range of firing temperature; and it is believed celadon and white porcelain were baked in high temperature of 1,150 to $1,250^{\circ}C$. It seems difference between refinement of source clay and firing temperature based on production times resulted from change in raw material supply and firing method pursuant to development of production skill. However, there was difference in production methods even at the same period and it is thought that they were utilized according to use purpose and needs instead of evolved development simply to one direction.
