The Noeun-dong Paleolithic site located at the construction area of Daejeon World Cup Stadium, has been excavated two times between 1998 and 1999. The site is situated at 60-75m above sea level on a gentle slope. According to the absolute dating results a

L'analyse des galets fractures decouverts sur les sols d'habitat de la grotto du Lazaret permet de penser que la cassure des galets se serait produite sur place dans la grotte, soit par des actions naturelles, soit par des actions des hommes prehistoriques. D'apres la comparaison des resultats obtenus par 1'etude exprimentale, les cassures des galets sont liees a plusieurs modes de fraturation. On peut seulement dire que les trois modes (1,3 et 5) sont susceptibles de donner des indications sur 1'aspect intentionnel de certains types de fracturation.

고고학자들은 발굴 후 발굴과정에서 기록된 사진, 그림, 구덩에 대한 데이터를 분석하는 것에 기초하여 연구한다. 각 데이터들은 연구자들의 연구 분야별로 석기, 식생, 지질, 유적지 및 지구 등으로 나뉘어져 있으며 한 유적지의 자료들을 각각 별도의 파일로 저장하고 있다. 따라서 현재 연구자들이 이러한 자료들을 연구에 활용한 수 있는 통합적 환경을 제공하지 못할 뿐만 아니라, 기존의 유적 및 유물들에 대한 체계적인 관리, 자료 상호간의 연관성 문제 등이 대두되고 있다. 따라서 이 논문에서는 중원지역의 구석기 유적지, 유물 및 지질 자료들을 하나의 데이터베이스로 저장하기 위한 모델링을 수행하였다. 이로 인해 기존의 개별적인 자료들을 하나의 자원으로 체계적 관리가 가능할 뿐만 아니라 각 자료들간의 상호 연관성 파악을 위한 기반을 마련한다.

Stone artefacts when flaked or used retain traces. It is my objectives to analyze such traces as observed on the artefacts collected and excavated from Chongong-ni and Suyanggae sites attributed to palaeolithic ages. Observations were made with 1) naked e

The stone artifacts in Bronze age from the Sinsongri sites in Seosan, Korea were studied on material characteristics and provenance presumptions. The use and rock names of the artifacts are a stone before processing, two semifinished stone arrowheads and a grinding stone plate by slates. In addition, there is semifinished stone arrowhead by andesitic rocks. The slate could be observed easily around the site, and the andesitic rock could be confirmed typical occurrences of the all kinds of rocks around the Kanwoldo and Hwangdori, Anmyun area above 10km from the site. As a result of analysis which is comparing between stone artifacts and same kinds of raw material rocks, the stone artifacts made by slates have similar lithology and geochemical characteristics however, the stone artifacts made by andesitic rocks are found a some different part of characteristics to the same kind of raw material rocks. Comparing of major, rare earth, compatible and incompatible elements about stones artifacts made by slates and by the same kinds of raw material rocks have same geochemical patterns. However stone artifacts made by andesites and the raw material rocks are confirmed some differences of geochemistry. Therefore the slate stone artifacts in Sinsongri site suggest that these are domestic-type which are made of the rocks around the site, and it was understood that the andesitic stone artifacts are foreign-type which need to get more geological survey and study about different volcanic artifacts of the site around the area.

A lot of dolmens without burial chamber have been brought to the light around Honam (southwestern provinces of Korea) area. Even though they are commonly classified as dolmens of surrounding stone type(圍石式), it seems necessary to put under the category of

The Piseo-ri site in Muan provides significant data in investigation on the Paleolithic sites in the southwest coast of Korea. Stratigraphic and geological analysis indicates that the characteristic of soil wedge can vary in accordance with soil property and relief of paleo-surface. Considering that the cultural layer was deposited after the Last Glacial Maximum, co-occurrence of the late Middle to early Upper Paleolithic stone tools suggests a possibility of redeposition of different ages resulted from active erosion. The result shows that the distribution of the Paleolithic tools and the property of soil wedge could be controlled by environmental conditions such as relief of paleo-surface and climate.

Neulgeori prehistoric site is located at Joong-ri Kwanin-myon Pocheon-si, Gyeonggi-do, where lots of stone artefacts were excavated. We investigated the petrological features of the artefacts through petrographical observation and modal analysis. In addition we estimated the provenance of the artefacts by means of the geological survey. The twelve stone artefacts used in this study are identified as ash tuff, lapilli tuff, granite porphyry, andesite and diorite porphyry. Various rocks were used for making flakes, whereas blades and debris were from the tuffaceous rocks. Lapilli tuff is considered to have been delivered from the Dongmakgol tuff in the Cheolwon basin, granite porphyry from the Cretaceous granite porphyry stocks cropped out at the southeastern Oksan-ri and eastern Yeoncheon areas. Andesite artefact would have been originated from the outcrops located at the northern part of the site, and diorite porphyry artefact from the southern part of the site. The stone artefacts investigated are estimated to have been transported from the area within 15 kilometers from the site.

pH control-precipitation method is used for recovery of EDTA from waste fluid of archeological waterlogged wood conservation treatment. EDTA has been used for eliminating of blacken effect in archeological waterlogged wood which was buried in the ground for long period of time. The black substance is generated by Fe$^{3+}$ in the soil reacted with tannin in the archeological waterlogged wood. In order to remove the black substance in archeological waterlogged wood, EDTA was used. The black substance is eliminated from wood as Fe-EDTA complex are formed, and EDTA is separated and precipitated from Fe-EDTA complexes at pH 2.68 or less. The result of analysis of the precipitated products and the commercial EDTA by FT-IR and FE-SEM showed that precipitated product by pH adjusted was not a type of Fe-EDTA complex, but pure EDTA. In this study, Fe$^{3+}$ from waste fluid of EDTA can be separated by HCl added. EDTA can be recycled by using the method of precipitation of EDTA in a strong acid.

Over the last three decades, advances in AMS (Accelerator Mass Spectrometry) and Noble Gas Mass Spectrometer make various application of terrestrial cosmogenic nuclides (CNs) to wide range of earth surface sciences possible. Dating techniques can be divided into three sub-approaches: simple surface exposure dating, depth-profile dating, and burial dating, depending on the condition of targeted surfaces. In terms of Korean landscape view, CNs dating can be applied to fluvial and marine terrace, alluvial fan, tectonic landform (fault scarp and faulted surfaces), debris landforms such as rock fall, talus, block field and stream, lacustrine and marine wave-cut platform, cave deposits, Pliocene basin fill and archaeological sites. In addition, in terms of lithology, the previous limit to quartz-rich rocks such as granite and gneiss can be expanded to volcanic and carbonate rocks with the help of recent advances in CNs analysis in those rocks.
