This paper attempts to reveal little-known pages from the history of relations between the peoples of Central Asia and Korea based on materials derived from written sources and modern scientific literature, as well as from medieval wall paintings from the early medieval Afrasiab Palace of Varhuman, the ruler of Samarkand, and from stone sculptures of Sogdian figures contained in Silla royal tombs. Korea's interest in the western lands led to its contact with Buddhism, which spread and later flourished in all three Korean kingdoms (Koguryo, Paekche and Silla). The spread of Buddhism in turn motivated a number of Korean monks to undertake pilgrimages to India via Central Asia. Hyecho, a young Silla pilgrim, left evidence of his journey via the South China Sea to India in 723 AD. Paul Pelliot discovered a report from Hyecho's journey entitled Notes on Pilgrimage to Five Regions in India (Wang Wu Tianzhuguo zhuan) in the Dunhuang caves in 1908. Hyecho's contributions are worthy of attention, substantially complementing knowledge available for this little-studied period in the history of South and Central Asia. The information contained in Hyecho's manuscript is, in fact, considered the most significant work of the first half of the 8th century. Research regarding the relationship between Central Asia and Korea remains underdeveloped. Existing historical evidence, however, including the above mentioned Samarkand wall paintings, depicts the visits of two Korean ambassadors to Samarkand, and evidence from Silla tombs suggests the presence of diplomatic relations in addition to trade between the two regions. Overall, the history of the relationship between Central Asia and Korea yields new insights into how and why these distant countries sustained trade and diplomatic and cultural exchange during this early period. Taking into account Korea's growing interest in Uzbekistan, especially in its history and culture, this article can act as a catalyst for studying the history of the two country's relations.

This paper presents the effects of an increase or a decrease of a power reserve by load flow calculations under the seasonal load patterns of each country for the future power shortages faced by the metropolitan areas or by the southeastern area of South Korea in North-East Asia. In this paper, the various cases of the power system interconnections in Far-East Asia are presented, and the resulting interconnected power systems are simulated by means of a power flow analysis performed with the PSS/E 28 version tool. Data for simulation were obtained from the 2-th long term plan of electricity supply and demand in KEPCO. The power flow map is drawn from simulated data and the comparative study is done. In the future, a power flow analysis will be considered to reflect the effects of seasonal power exchanges. And the plan of assumed scenarios will be considered with maximum or minimum power exchanges during summer or winter in North-East Asian countries.

Land cover (LC) is an important factor in socioeconomic and environmental studies. According to various studies, a number of LC maps, including global land cover (GLC) datasets, are made using polar orbit satellite data. Due to the insufficiencies of reference datasets in Northeast Asia, several LC maps display discrepancies in that region. In this paper, we performed a feasibility assessment of LC mapping using Geostationary Ocean Color Imager (GOCI) data over Northeast Asia. To produce the LC map, the GOCI normalized difference vegetation index (NDVI) was used as an input dataset and a level-2 LC map of South Korea was used as a reference dataset to evaluate the LC map. In this paper, 7 LC types(urban, croplands, forest, grasslands, wetlands, barren, and water) were defined to reflect Northeast Asian LC. The LC map was produced via principal component analysis (PCA) with K-means clustering, and a sensitivity analysis was performed. The overall accuracy was calculated to be 77.94%. Furthermore, to assess the accuracy of the LC map not only in South Korea but also in Northeast Asia, 6 GLC datasets (IGBP, UMD, GLC2000, GlobCover2009, MCD12Q1, GlobeLand30) were used as comparison datasets. The accuracy scores for the 6 GLC datasets were calculated to be 59.41%, 56.82%, 60.97%, 51.71%, 70.24%, and 72.80%, respectively. Therefore, the first attempt to produce the LC map using geostationary satellite data is considered to be acceptable.

South Korea's 'Green Revolution', which is considered to be one of Asia's most successful programs of integrated rural development, has achieved two main objectives: (1) bringing the country closer to self-sufficiency and (2) narrowing the income gap between rural and ruban incomes and thus allowing agriculture to participate in the nation's economic growth.

According to the literature, soybean cultivation originated from Wang-Gong (B.C. 685-643) of China who brought it from northeast Asia, for the first time. FUKUDA, of Japan divided soybean into three species-the wild, the cultivated and the intermediate. From the result of that study, he concluded that the soybean originated in northeast Asia. But Wang Kum Rung of China insisted that soybean originated in Hwa-Nam, because the soybean is a shortday plant and the agricultural history of Hwa-Nam, south of China, is older than that of northeast Asia. However, agriculture in northeast Asia had been already begun about B.C. 4000-6000 and the origin of culture cannot be decided only by photosensitivity. It has been proved that soybeans found in Korea were same as the ones of B.C. 2000. The soybeans of northeast Asia meet the conditions of the probable place of origin of cultivated crops established by Vabilov. Accordingly it is concluded that soybean has been originated from northeast Asia.

Most of lichens are formed by Ascomycota, less than 1% are lichenized Basidiomycota. The flora investigation of lichenized Ascomycota of South Korea has been well studied in the past three decades; however, prior to this study, none of basidiolichens was discovered. During the recent excursion, an unexpected clavarioid basidiolichen, Sulzbacheromyces sinensis was collected. Morphology and ecology has been recorded in detail. DNA was extracted, and ITS, 18S, 28S nuclear rDNA were generated. In order to further confirm the systematic position of the Korean specimens, maximum likelihood and Bayesian inference analysis including all the species of the order Lepidostromatales were conducted based on the ITS. As a result, the phylogenetic tree of the order Lepidostromatales was reconstructed, which differed from the previous studies. The inferred phylogenetic tree showed that species of Sulzbacheromyces in three different continents (Asia, South Africa and South America) were separated into three clades with support. In this study, the species worldwide distribution map of Lepidostromatales was illustrated, and S. sinensis had a widest distribution range (paleotropical extend to the Sino-Japanese) than other species (paleotropical or neotropical). Prior to this study, the range of distribution, southernmost and northernmost points and the fruiting time of S. sinensis were recorded, and the genus Sulzbacheromyces was firstly reported from Korean peninsula and Philippines.

In Japan, the wild house mouse Mus musculus consists of two lineages, one from Southeast Asia (Mus musculus castaneus; CAS) and one from northern Eurasia (Mus musculus musculus; MUS). However, the exact origins of the parental lineages are unclear. A recent work using mitochondrial sequences revealed that Japanese CAS and MUS are closely related to haplotypes from South China and the Korean Peninsula, respectively. Recent phylogeographic analyses using nuclear gene sequences have also confirmed a close relationship between Japan and Korea in the MUS component. However, the Japanese CAS components in the nuclear genome are likely to be unique and to differ from those of other CAS territories, including South China. Although the origins are still unresolved, these results allow us to conclude that two areas of the continent, South China and the Korean Peninsula, are the primary source areas of Japanese wild mice and suggest pre-historical introductions associated with certain historical agricultural developments in East Asia.
