The liberated korea has the estimated population 16 million in 1945, and added 2.5 million just after an year. The korean repatriates returned by way of 2 main routes. The returnees, Wol-Nam-Min(former residents in north korea), and repatriates from Manchuria came into south korea over the 38th division line. The other repatriates from japanese islands and pacific areas came into Busan port and the vicinity. The repatriates who returned from the China and the Japanese islands made up about 80% of the total added population. However, the influx of overseas repatriates who explosively increased between 1945 and 1946, declined abruptly in April of 1946, and at last illegal re-emigration group to Manchuria and Japan Appeared, who had repatriated from those areas. This study deals with the "re-migration phenomenon of 1946" in korea, mainly focuses on 1) the motivation for those who decided to remigrate, their prospects of resettlement in Manchuria and post war japan after re-migration, 2) the structural problems of the Korean society in 1946-1947, and 3) the social recognition for the people who letf for Manchuria and Japan. This study proved the cause and background of re-migration phenomenon. The Manchuria case, the local authorities wanted farmers and peasants who could cultivate the abandoned land which had been originally pioneered and reclaimed by korean poor peasants, who repatriated to korean peninsula. On the other hand, the korean repatriates had a hard time in tenanting farmland, and so much difficulty in getting farming tools including fertilizer. That's why they left korea for Manchuria again. The Japanese case, the korean repatriates had a tough life owing to the restriction of properties left in japan, while the inflation and food shortage in korea got worse and worst. Accordingly, many koreans tried illegal entrance into post war japan. This study is a part of clarifying the universality and specificity of post war repatriation and migration issues developed in the south Korea. Through this study, we can find how difficult it is for newly liberated areas to accommodate repatriates and make them ordinary nationals in harmonic way with successful social integration. and we can observe the social aspect and administrative ability of newly liberated south korea in detail, Because the present korea has faced with so many problems connected with immigration workers and re-setting with korean communities abroad, we should introspect these historical experience of our own.

This paper analyzes Japan's consignment management of the Chosun Railway to the South Manchuria Railway. While Chosun Railway was entrusted, its management style differed significantly from that of Japan's direct management. After eight years of trust management, the direct management of Chosun Railway was returned to Japan. This of beyond border trust management is very rare. In addition, the management of Chosun Railway by South Manchuria Railway, which had an operation style similar to that of a private company, led to changes in Chosun Railway. This research analyzes the four key traits of South Manchuria Railway's consigned management. The first key trait is the initial Korean infrastructure and operation separation model. The second key trait is the international transportation and administration segregation. The third key trait is that it expanded the railway related businesses and led to the establishment of private railway companies. The fourth key trait is that the continental linked transportation was activated. Through analyses, it would be to create a comparative study of the resulting East Asian countries' operations. Furthermore, this research will in investigating the nature of Chosun Railway.

This study attempts to analyze the difference among the variations of ecological distribution in Gobi desert and Manchuria through satellite based land cover classification. This was motivated by two well-known facts: 1) Gobi desert, which is an old source region, had been gradually expanded eastward; 2) Manchuria, which is located in east of Gobi desert, was observed as a new source region of yellow dust. An unsupervised classification called ISODATA clustering method was employed to detect the land cover change and to characterize the status of desertification and its expanding trends using NDVI (Normalized Difference Vegetation Index) derived from VEGETATION sensor onboard the SPOT satellite for 1999 and 2007. We analyzed NDVI annual variation pattern for every classes and divide into 5 level according to their vegetation's density level based on NDVI. As results, Gobi desert is showed positive variation: a decrease $78,066km^2$ in central Gobi desert and out skirts of Gobi desert (level-0) but Manchuria area is worse than previous time: an increase $25,744km^2$.

This paper analyses the decision process of the Gilhoe Line construction of the Manchurian Railway and consignment process of the North Korea Line to the South Manchuria Railways as part of the 12-year Chosun railway plan. It was found that these two events were connected and could be explained by Japan's consistent continental policy, which had expanded its territory toward China. This paper explicates Japan's railroad policy and the characteristics of the Chosun railway. Moreover, evidence to identify connections among Japan's national railway, the Manchurian railway, and the Chosun railway has been scrutinized. One territory policy between Chosun and Manchuria is also examined. Comparison of new resources on the Gilhoe Line construction of the Manchurian railway and the 12-year plan of the Chosun railway, and their correlations, is expounded. This paper elucidates that the Gilhoe Line construction and the North Korea line consignment operation by the South Manchuria Railways had the intention of obtaining Japanese military and economic supremacy over East Asia.

In 2007, according to the records, I made an on-the-spot survey of the place where Doju Cho Jeongsan and his family might have lived in exile in Manchuria and released a paper in which I decided that the site could be the Shuidongchun (village) of Luotongshanzhen in Liuhexian, Jilin Province. Thereafter, sponsored by the Doju Cho Jeongsan's Memorial Project from 2008 to 2013, many times, I carried out the field investigations and researches on Liuhexian, including the visits of the institutions which have the historical documents, in order to find the data related to the participation of him and his family in the anti-Japanese movement. I was, hence, able to reconfirm that the village had been the place of their exile, based on my collected data and the oral reports which the local historians and ethnic Korean elders had provided. In this study, using the historical documents and maps and the oral materials, I made an attempt to prove the historical truth thoroughly once again. First, the existing sources of Doju Cho and his family's settling in Manchuria from March 1909 to 1917, were carefully analyzed which were described in The Jin-gyeong. In doing so, the misspelling of the names and the spatio-temporal errors of the people's activities were corrected. Next, I researched on another town, Shuitungou of Liuhexian in Fengtian Province (in West Gando of Manchuria), which it is known that Doju and his family stayed in, and the Laogushan (mountain), which it is believed that Doju cultivated himself in. Finally, through the attempt, I reached the conclusion that Doju and his family had settled at Shuidongchun (once called Shuidonggou or Shuitongchun) of Luotongshanzhen (once called Datonggou) in Liuhexian, Jilin Province. In the Liuhexian-related documents and maps published in the eras of Republican China and Manchuria, the place name called Shuitungou was not found. However, I discovered a map in the era of Republican China on which Shuitongchun was recorded as Shuidonggou. In addition, considering the administration system of Republic China, tun(屯) and gou(溝) could not be used together in the place names. Accordingly, Shuitungou was more likely misspelled as Korean people in those days mispronounced Shuidonggou. Furthermore, people in China has habitually called the Dagushan(大孤山), located in the north of Gushanzizhen of Liuhexian, as the Laogushan(老孤山). This means that the Korean people who lived in the area then perhaps recorded the mountain as the Nogosan(老姑山), the mountain of the old goddess, according to Korean enunciation, because they had the custom of worshipping the mountain goddess. I tried my best to find the historical documents regarding Doju and his family's anti-Japanese activities to prove the location of exile in which they settled in northeastern China (Manchuria). However, I was not able to reach the initial goal completely due to the shortage of objective evidences, only to leave tasks to be solved. I hope that this study can give a little help to researchers who are interested in this matter.

In our present investigations, distributions of Korean Aceraceae with single genus composed of 16 species, 14 varieties and 1 form were studied. Distributional atlases were made by UTM grid map and drawing methods have been previously described (Distribution Atlas of Plants of Korea I, II, and III). Acer okamotoanum and A. takesimense of Korean endemic species are commonly distributed in Dagelet Island but the latter also in such islands as Quelpart, Wan-Do and Heucksan-Do. A. palmatum var. nakaii is found in the middle and the northern parts of the subtropics, and A. micro-sieboldianum and A. nudricarpum restricted to the middle part of the country are endemic species of Korea. A. barbinerve and A. tegmentosum as species from the north are distributed to the top of Mt. Chiri in the south and are also found in Mt. Nangrim and Baiktu in the north. A. ginnala and A. mono are commonly distributed in Liaotung-Pantao and Shantung-Pantao, or Chinese peninsulas, and South Manchuria with Korean Peninsula. A. barbinerve, A. tegmentosum, A. triflorum, A. tschonoskii and A. ukurunduense in south Manchuria, north Manchuria and Korea are florae derived from Manchuria, and A. japonicum, A. momo var. ambiguum, A. mono var. savatieri, A. palmatum var. matsumurae and A. ukurunduense var. pilosum appear in Korea and Japan.

The northeast part of China(hereafter Manchuria) is one of Asian dust source regions along with Gobi, Inner Mongolia and Loess Plateau. In this study, a geographical survey over the area was carried out to determine its soil characteristics in June 2009. It revealed that some parts of the area, especially near Keerchin desert, consist of alkali clay soil mixed up with sand. Manchuria, where is a vast cornfield, can be a potential source region of Asian dust from fall to following spring after harvesting. The frequency of Asian dust over the region from 1996 to 2009 was examined using 3-hourly GTS SYNOP data and it showed that the occurrence of Asian dust over the region is high in the springtime. It was also revealed that snow cover is the key parameter affecting on the frequency through the analysis of NCEP reanalysis data. To scrutinize the path and structure of Asian dust from Manchuria, the event on 3~4 April 2008 and 25 January 2010 were intensively investigated with regard to features of synoptic weather patterns, satellite imagery, airstream, naked eye-observations, concentrations of PM10, 2.5 and 1.0. For this case, the Asian dust from the area reached to Korea less than a day. However, the duration time of the dust in Korea was short (< 7 hours). The average of hourly PM10 reached up to $340{\mu}g/m^{3}$ at Baengnyeondo during the period. The high PM2.5 and PM1.0 concentrations were also observed at several sites in Korea, indicating that air pollutants could be transported along with the dust.

Samples of Siberian chipmunks (Tamias sibiricus borberi ) from Korea were analyzed by multivariate, air-drying , and blot-hybridization methods in order to determine the degree of variations of morphological characters, chromosomal karyotype, and mtDNA restriction fragment patterns, respectively, Moreover, morphometric characters of samples of Siberian chipmunks from Manchuria(T.sibiricus orientalis) were also analyzed in order to clarify the taxonomic status of the subspecies barberi. Siberian chipmunks from six localities in Korea were in morphometric characters more or less similar with one another and Siberian chipmunks from Manchuria were not so distinct enough to from a subgroup. Siberian chipmunks from Four localities in Korea were identical in their karyotypes (2n=38) : samples from three localities in Korea were nore or less similar in their mtDNA fragment patterns. Siberian chipmunks from Korea appeared to be a omogeneous population and as noted by Corbet (1978) subspecies barberi is the synonym of subspecies orientalis. The scientific name of Siberian chipmunks from Korea and Manchuria is T. sibiricus orientalis, although systematic studies with the samples from North korea, Manchuria and China will be necessary for their taxonomic reconsideration.

In order to examine the variational features of Asian dust outbreak in recent years, observed WMO synop data were employed for the period from 1996 to 2007. We first divided Asian dust source regions into four subregions; 1) Taklamakan, 2) Gobi, 3) Inner Mongolia-Manchuria and 4) Loess, and the meteorogical variables such as wind speed, precipitation and threshold wind speed observed during the Asian dust outbreak period were compared with those during non-Asian dust period. The results showed that temporal variation of occurrence frequency of dust outbreak had a strong positive correlation with the frequency of strong wind speed and low precipitation in each of the 4 source regions. Spatial distributions of frequency of dust occurrence after 2002 showed increasing trend in Gobi and Inner Mongolia-Manchuria but decreasing trend in Loess region. This is showing a shift in main source region toward Northwest, especially since 2003.

Four external and 27 cranial characters of Korean field mice (Apodemus peninsuluek from nine localities in eastern Asia, representing ave subspecies, were analyzed by multivariate statistical methods. Three forms were recognized: a large-size form from Korea (subspecies peninsulael, southern Manchuria (praeto4, and northern Manchuria (majofi a middle-size form from urestern Siberia (tschergal and southuvestern China (sowerbyi); a small-size form from northeastern China (sowerbyi). It is also revealed that variations among the three forms are clinal rind circular. It is confirmed that Apodemus peninsuloe could be classified into two subspecies (peninsulae and sowerbyl) within the distribution range in the continent of Asia, as noted tv Corbel (1978). However, it is found that subspecies peninsulae includes praetor and moior and that subspecies sowerbyi includes tscherga, indicating that subspecies tscherga is not the synonym of subspecies peninsulae, but that of subspecies sowerbyi.
