Karst in Arctic and Subarctic region in North America contains a wide variety of surficial karst landform characteristics due to not only extensive glacial activities, but also interglacial karst processes during the Pleistocene age.(omitted)

Chronology, Paleolithic typology and ecology in Pleistocene East and Southeast Asia have been a constant source of debate and controversy. However, recent significant advances in the fields above-mentioned have improved this condition greatly. The 'ultima

The Late Pleistocene pollen record from the Poil-dong, Uiwang, Kyunggi-do, reveals that mixed coniferous and deciduous broadleaved forests were spread along with herb and fern understory. Palynofloral changes reflect climate fluctuations. From ca. 43,100 to 41,900 cal. yr BP, a mixed coniferous and deciduous broadleaved forest combined with open grassland occupied the study area, which indicates cooler condition than today. During the period of ca. 41,900-41,200 cal. yr BP, along with fern understory a decrease in subalpine conifers and an increase in temperate deciduous broadleaved trees suggest a climatic amelioration. A climatic deterioration, as evidenced by an increase in subalpine conifers and a decrease in the density of vegetation cover, occurred from ca. 41,200 to 39,700 cal. yr BP.

To delineate Late Pleistocene paleoceanographic change of the West Pacific, we analyzed the oxygen and carbon isotopic ratios of two planktonic foraminifera species (G. sacculifer and N. dutertrei) from a piston core (KODOS-313) taken from the West equatorial Pacific, and they are compared with the published results of the East Pacific (ODP site 847 and RC 11-210), in terms of relative amounts and mass accumulation rates of $CaCO_3$ and eolian component, back to marine isotopic stage (MIS) 6. Differences in oxygen and carbon isotope values between two foraminifear species ($0.75%_{\circ}$ in ${\delta}^{18}O$, $0.05%_{\circ}$ in ${\delta}^{13}C$) are less than those of the East Pacific ($1.30%_{\circ}$ in ${\delta}^{18}O$, $0.14%_{\circ}$ in ${\delta}^{13}C$), which indicates smaller vertical contrasts in both temperature and nutrient between mixing-zone and thermocline in the West Pacific. Strong deviation in${\delta}^{18}O$ of G. sacculifer from SPECMAP suggests the carbonate fraction of KODOS-313 was subjected to partial dissolution by bottom water under lysocline. Lower accumulation rates of $CaCO_3$ and eolian component during glacial times are likely due to low sedimentation rate (ave. 0.75 cm/1000 yr) combined with carbonate dissolution in KODOS-313 site. However, the high $CaCO_3$ contents during the glacial periods clearly follow the general pattern of equatorial Pacific ocean.

The first well-preserved an immature fossil skeleton of Pleistocene age in South Korea was found at the quarry of Hungsu cave which consists of the Turubong Cave Complex, Ch'ongwon, Korea. This fossil remain has been designated as "Hungsu Cave Child". Associated with the individual were a small number of stone artifacts. While a precise date for this site is not available yet, the presence of fauna would suggest a warm period of an Upper Pleistocene date. Metric and non-metric methods are used for the description of the Hungsu child's skeleton. This fossil has been assigned a developmental age of 5 years, but can be considered to be the range of 4 to 6 years. Estimated cranial capacity ranged from 1,260 to 1,300 CC and the estimated stature from 110 to 120cm. The Hungsu child is differentiated by the superiority in size of skull, cranial length and height, and, most significantly, its greater parietal arc. On the basis of comparison of the total cranical characteristics of Hungsu child and other samples including hominid fossils and modern man of East Asia, it is assumed that Hungsu child can currently, be classified as "an anatomically modern man or anatomically Homo sapiens".

To understand the natural environments and human cultures in the Yellow Sea regions, this paper deals especially the climate and sea level fluctuation in the Yellow Sea and its surrounding region in the period of late Pleistocene (125, 000 yr BP) to Holocene. During the glacial maximum (about 15, 000 yr BP to 18, 000 yr BP), the climate might be cold and arid. These arid climate in the Yellow Sea region did make desertization possible. Possible human culture exchanges between China, Korea and Japan might be carried in a easy way, because the entire basin of the Yellow Sea was exposed as land. Paleoshorelines of the Yellow Sea in the period of 10, 000 yr BP, 9, 000 ry BP and 6, 000 yr BP are presented and sea level fluctuation curve from 37, 000 yr BP (late Pleistocene) to present (late Holocene), for the first time, is presented based on a careful reconsideration of existing old data and recent new data.
