The impact of the interannual climatic variability on the vegetation sensitively appears in the timing of phenological events such as green-up, mature, and senescence. Therefore, an accurate and temporally high-resolution NDVI dataset will be required for analysis on the interannual variability of the climate-vegetation relationship. We constructed a daily 8km NDVI dataset over Eurasia based on the 8km tiled data of Pathfinder A VHRR Land (PAL) Global daily product. Cloud contamination was successfully reduced by Temporal Window Operation (TWO), which is a method to find optimized upper envelop line of the NDVI seasonal change. Based on the daily NDVI time series from 1982 to 2000, an accurate (daily) interannual change of the phenological events will be analyzed.

Several theories about the ancestry of the Khazars and the origins of the Khazar state have been suggested to date. None of them provides a comprehensive solution for the controversial data of the written sources on the early history of the Khazars. This article investigates a possible link between the title of Kagan-Bek of the Deputy Kagan of the Khazars and a similar title Ellac/Ilek of the Akatsir-Huns. This study of the title argues for statehood and political culture connections between the earliest Turkic tribes of Western Eurasia and the Khazars and Turks of Central Asia.

This article demonstrates the significance of long-distance networks formed by traders from Afghanistan and Central Asia to the forging of present-day transregional connections within Asia. It identifies two connective corridors authored by these traders: a 'Eurasian corridor' connecting East Asia to post-Soviet Eurasia and extending into Western Europe and a 'West Asian corridor' involving traders originally from Central Asia linking East Asia to Turkey and the Arabian Peninsula. Empirically, the paper documents and analyses the varying cultural and political orientations of traders operating along these networks, and ways in which specific nodes in the networks contribute to their activities as a whole. Conceptually, the papers suggest that the study of 'inter-Asian' connections stands to benefit from deploying oceanic and inland models of geography in a non-dichotomous manner.

This research is an analysis of the water vapor transport change Into the continent due to the global warming effect with the general circulation models. Water vapor transport change from ocean to land increases through the year due to CO2 doubling effect. In Eurasia, it indicates an increase about 170∼350${\times}$06 Mt/day the whole year. In Africa, it shows an decrease every month except November, especially there is the maximum decrease about -350${\times}$106 Mt/day during August-September. In other continents, excluding Eurasia and Africa, the change of water vapor transport vary with the month below $\pm$8.0${\times}$106 Mt/day with the unsystematic patterns. In Eurasia, the change of water vapor transport increases as a whole, but it decrease in desert areas which occupy a high area-ratio. Therefore, except desert areas, the amount of the growth in water vapor transport change concentrate on Asian monsoon area. As a result of monsoon strengthening, available water will grow considerably at the asian monsoon areas.

The characteristics of the rainfall events on the Korean peninsula have been investigated by means of regional and global observational data collected from 1954 to 2004 with an emphasis on extreme cases $80\;mm\;day^{-1}$. According to our analysis, long-term annual rainfall anomalies show an increasing trend. This trend is pronounced in the month of August, when both the amount of monthly rainfall and the frequency of extreme events increase significantly. Composite maps on August during the 8 wet years reveal warm SST anomalies over the eastern Philippine Sea which are associated with enhanced convection and vertical motion and intensified positive SLP over central Eurasia during August. The rainfall pattern suggests that the most significant increase in moisture supply over the southern parts of China and Korea in August is associated with positive SLP changes over Eurasia and negative SLP changes over the subtropical western Pacific off the east coast of south China. The frequent generation of typhoons over the warm eastern Philippine Sea and their tracks appear to influence the extreme rainfall events in Korea during the month of August. The typhoons in August mainly passed the western coast of Korea, resulting in the frequent occurrence of extreme rainfall events in this region. Furthermore, anomalous cyclonic circulations over the eastern Philippine Sea also promoted the generation of tropical cyclones. The position of pressure systems - positive SLP over Eurasia and negative SLP over the subtropical Pacific - in turn provided a pathway for typhoons. The moisture is then effectively transported further north toward Korea and east toward the southern parts of China during the extreme rainfall period.

Recently, with the US protection trade trend, South Korea 's exports to the US have shrunk and the need to pioneer emerging markets in Eurasia has increased. Due to the bankruptcy of Hanjin Shipping, a large Korean national shipping company, the necessity of securing transportation that can replace the Asian - European shipping route has emerged. Moreover, as the international trade and logistics environment is rapidly changing due to the spread of electronic commerce, it is time to prepare for the environment where IT technology is applied to international logistics activities. Therefore, this study was carried out to establish information strategy of Eurasia logistics information sharing platform from Korean perspective through comparison of logistics information level of Eurasian countries. This study aims at standardization direction for supporting logistics activities between Eurasian countries, providing customs clearance and logistics services without interruption, providing information for expanding business of trade companies, and building information linkage infrastructure for expanding cooperation between logistics companies across countries. Through this study, it is expected that logistics activities through information sharing among countries will be actively carried out.

The purpose of this study is to examine the main features of South Korea's New Northern Policy and to make some suggestions for cooperation with neighboring countries' initiatives. The New Northern Policy encompasses the whole of Eurasia, but the starting development area would be the border region of the Korean Peninsula. In this viewpoint, this study examines the Belt and Road Initiative of China, the New Eastern Policy of Russia and the Steppe Road Initiative of Mongolia, and presents the characteristics, problems and some implementation strategies of the New Northern Policy. Apart from the future possibilities of the regional cooperations that include North Korea, it would be necessary for South Korea to secure and expand the possible opportunities for "Korea-China-Mongolia-Russia" cooperation. In order to create a close cooperative environment with North Korea in the future, it would also be necessary to build a maritime route, with port development around major border regions on the Korean Peninsula, including Russia, and to develop the port-railway intermodal transportation system with neighboring countries. South Korea need to actively cooperate with neighboring countries to develop the new Eurasia logistics routes would be more favorable to the Korean Peninsula in preparation for the time when the North Korean nuclear issue will be resolved.
