The purpose of this thesis is to find out how the upper garment styles in the Ancient East and est had been influenced with each other. Analytical studies conclude the fellowing findings: 1) Upper garment styles in the feat Asia and the Egypt already highly developed in 28th century B.C. and show us the original style of the wrap-over to the left and that of the round neckline(曲領). Upper garment of the open in the center front shown in Babylonia in 18th century B.C. had been inherited to the caftan of the Hebrew and later succeeded to the Persia. 2) The tunic styles of the round neckline, the wrap-over to the left and the open in the cotter front, which were the basic styles of the upper garment, had teen widely accepted to the central Asia and the East Asia, as well as the Northern Europe, from the West Asia. 3) The styles of the wrap-over to the right originated from China since it had begun to show in the Shang Dynasty(商代, 殷代). 4) The East and the West costumes had been very much intermixed in 4th century B.C. Alexander the Great of Macedoria in 4th century B.C. expanded his territory to the central Asia and built up the Bacteria, when the most western civilization had been greatly transmitted to the Orient. Meanwhile the tunic being clad in the West and Central Asia began to be worn by soldiers in the period of the Warring States in China (326-299 B.C.) and afterwards worn even by civil officials since the age of the T'ang Dynasty of China. 5) The Upper garments of the open in the center front, the wrap-over to the right, the wrap-over to the left and the round neckline were found in Korea, which mean that the upper garment styles in the Ancient Korea were intermixed of the factors from the West Asia, the central Asia and the East Asia. 6) The styles of costume in the East Asia were influenced by the West Asia through the central Asia. The upper garment styles Europe were also influenced by the West Asia. Thus the upper garment styles in the Ancient East and West had been mutually affected with each other.

This study is a comparative analysis on the variabilities of spring precipitation and atmospheric circulations of 500hPa surfaces between dry years and wet years over the Korean Peninsula. The distribution of variabilities of precipitation in spring are different from month to month. In March, the pattern is west-high and east-low, in April, north-high and south-low, in May, east-high and west-low respectively. In the distribution of 500hPa geopotential height anomaly, dry years of March show west-high and east-low pattern in that negative anomaly zones are formed around the Korean Peninsula and western coast of the northern Pacific Ocean, and positive anomaly zones are formed in the inland of East Asia centered on Siberia. Consequently, the Korean Peninsula and neighboring regions experience dry season when the zonal flows are strong with the positive anomaly zones of zonal components. On the contrary in the wet years the westerlies are weak since the pattern is east-high and west-low in which the positive anomaly zones are formed over the Korean Peninsula centered on the Aleutian Islands and western coast of the northern Pacific Ocean and the negative anomaly zones are formed in the inland of East Asia centered on Tibet Plateau and Siberia. The dry years of April and May show north-high and south-low patterns in that negative anomaly zones are found from the center of the northern Pacific Ocean to the eastern coast of East Asia, and the positive anomaly zones are found in the center of East Asia extending from Aleutian Islands to Tibet Plateau. On the contrary, in the wet years the patterns show south-high and north-low. This study identified not only that there are contrary atmospheric circulation patterms between dry years and wet years over Korean Peninsua in spring, but also there are different atmosphric circulation patterns between early and late spring.

Land evaporation contribution to precipitation over East Asia is studied to understand terrestrial moisture source of continental precipitation. Moisture recycling of precipitation relying on terrestrial evaporation is estimated based on the analysis method of Van der Ent et al. (2010). We utilize HadGEM2-AO simulations for the period of 1970~1999 and 2070~2099 from RCP8.5. Globally, 46% of terrestrial precipitation is depending from continental evaporation. 58% of terrestrial evaporation returns as continental precipitation. Over East Asia, precipitation has been affected by local evaporation and transported moisture. The advection of upwind continental evaporation results from the prevailing westerlies from the midwestern of Eurasian continent. For the present-day period, about 66% of the precipitation over the land of East Asia originates from land evaporation. Regionally, the ratios change and the ratios of precipitation terrestrial origin over the Northern inland and Southern coast of East Asia are 82% and 48%, respectively. Seasonally, the continental moisture recycling ratio is larger during summer (JJA) than winter (DJF). According to RCP8.5, moisture recycling ratio is expected to change. At the end of the 21st century, the impact of continental moisture sources for precipitation over East Asia is projected to be reduced by about 5% compared to at the end of 20th century. To understand the future changes, moisture residence time change is investigated using depletion and replenishment time.

Plecoglossus altivelis (ayu) is an amphidromous fish widely distributed in Northeastern Asia from the East China Sea to the northern Japanese coastal waters, encompassing the Korean Peninsula within its range. The shore lines of northeastern region in Asia have severely fluctuated following glaciations in the Quaternary. In the present study, we investigate the population genetic structure and historical demographic change of P. altivelis at a population level in East Asia. Analysis of molecular variance (AMOVA) based on 244 mitochondrial control region DNA sequences clearly showed that as the sampling scope extended to a larger geographic area, genetic differentiation began to become significant, particularly among Northeastern populations. A series of hierarchical AMOVA could detect the genetic relationship of three closely located islands between Korea and Japan that might have been tightly connected by the regional Tsushima current. Neutrality and mismatch distribution analyses revealed a strong signature of a recent population expansion of P. altivelis in East Asia, estimated at 126 to 391 thousand years ago during the late Pleistocene. Therefore it suggests that the present population of P. altivelis traces back to its approximate demographic change long before the last glacial maximum. This contrasts our a priori expectation that the most recent glacial event might have the most crucial effect on the present day demography of marine organisms through bottleneck and subsequent increase of effective population size in this region.

This paper is extended the meaning and period of CONICAL HAT. That is, the race in Central Asia and Western Asia have worn the conical hat before Scytian appeared. One in conical hat puts on the clothes of two-piece style and has the lifestyle. a horse riding and nomadism. Besides the race originate into the Indo-European language family. On the whole the conical hat has relations with the region and is classified into two groups. Scytian and Klin-Yar style. First. the Scytian style of low hat forms the seam of two-piece and is discovered in Southern Russia. Central Asia and East-Northern Asia. Second, the Klin-Yar style of high hat forms the one piece and generally is discovered in Asia Minor and west of Altai. Until now the moaning of the conical hat has focused on the military. However, one in Central Asia and Western Asia is mostly a king. nobility and god. Therefore, in addition to the meaning of military. I estimate that the conical hat may be expressed as the noble status.

Asian Dust is a seasonal phenomenon which affects much of East Asia mostly in spring. The dust and sand storm originate in the deserts of Mongolia. northern China, and Kazakhstan. Asian Dust is carried eastward by prevailing winds, and pass over China, the Korean Peninsula. and Japan. In recent years, Republic of Korea, China, and Japan have participated in projects associated with implementation of observation network and reforestation in the source region. The information of Asian Dust can be exchanged in real time among the east Asian countries through the international co-operation.

Acervus (Pyronemataceae, Pezizales) is a saprobic genus in Pezizomycetes, characterized by colored apothecia, subcylindrical to cylindrical asci and guttulate ascospores. We collected four Acervus samples from China and Thailand. Descriptions and illustrations are introduced for all fresh samples. One new record of A. globulosus from Thailand, one new species, A. rufus, two known species, A. epispartius and A. stipitatus from China are reported. Phylogenetic analysis based on five genes, the large subunit rRNA (LSU), the translation elongation factor-1 alpha (tef1-α), the second largest subunit of RNA polymerase II (rpb2), the largest subunit of RNA polymerase II (rpb1), and the small subunit rRNA (SSU), revealed the distinct position of the new species. The new species is set apart by its red apothecia. A key to Acervus species is also given.

This study compares the summer monsoon circulations during a heavy rainfall period over the Korean peninsular from 11 to 18 July 2004, simulated by three widely used regional models; WRF, MM5, and RSM. An identical model setup is carried out for all the experiments, except for the physical option differences in the RSM. The three models with a nominal resolution of about 50 km over Korea are nested by NCEP-DOE reanalysis data. Another RSM experiment with the same cumulus parameterization scheme as in the WRF and MM5 is designed to investigate the importance of the representation of subgrid-scale parameterized convection in reproducing monsoonal circulations in East Asia. All thee models are found to be capable of reproducing the general distribution of monsoonal precipitation, extending northeastward from south China across the Korean peninsula, to northern Japan. The results from the WRF and MM5 are similar in terms of accumulated precipitation, but a slightly better performance in the WRF than in the MM5. The RSM improves the bias for precipitation as compared to those from the WRF and MM5, but the pattern correlation is degraded due to overestimation of precipitation in northern China. In the comparison of simulated synoptic scale features, the RSM is found to reproduce the large-scale features well compared to the results from the MM5 and WRF. On the other hand, the simulated precipitation from the RSM with the convection scheme used in the MM5 and WRF is closer to that from the WRF and MM5 simulations, indicating the significant dependency of simulated precipitation in East Asia on the cumulus parameterization scheme.

The objective of this study is to evaluate the applicability of Land Surface Model (LSM) for estimating the runoff on East Asia. Global geographical and weather data are used as input for the model and for the model verification, the simulated runoff results are compared with observed data from 34 global observation stations provided by Global Runoff Data Center (GRDC). K$\ddot{o}$ppen's climate zone is used to calculate the model parameter for ungaged basins. As a result, the simulated runoff shows good performance comparing with observed data in 17 basins assumed as ungaged basins. The Hydrologic components on East Asia area are estimated from the model and the continental water balance components are seasonally similar to each country. Also, it reveals that runoffs from southern China, Japan and Taiwan are much higher than those from mongolian and northern China.
