The GOSAT (Greenhouse gases Observing SATellite) data provide new opportunities the most regionally complete and up-to-date assessment of $CO_2$. However, in practice, GOSAT records often suffer from missing data values mainly due to unfavorable meteorological condition in specific time periods of data acquisition. The aim of this research was to identify optimal spatial interpolation techniques to ensure the continuity of $CO_2$ from samples taken in the North East Asia. The accuracy among ordinary kriging (OK), universal kriging (UK) and simple kriging (SK) was compared based on the combined consideration of $R^2$ values, Root Mean Square Error (RMSE), Mean Error (ME) for variogram models. Cross validation for 1312 random sampling points indicate that the (UK) kriging is the best geostatistical method for spatial predictions of $CO_2$ in the East Asia region. The results from this study can be useful for selecting optimal kriging algorithm to produce $CO_2$ map of various landscapes. Also, data users may benefit from a statistical approach that would allow them to better understand the uncertainty and limitations of the GOSAT sample data.

본 논문의 목적은 지난 2010년 이후 우리의 수출 대상인 아시아, 북미, 유럽, 중남미, 중동, 아프리카를 중심으로 수출액의 상승률 동향과 변동성 그리고 상관관계와 모형분석 등을 살펴보고 향후 성장 방향을 찾아보는데 있다. 분석 결과 아시아, 북미, 유럽, 중남미, 중동, 아프리카 순으로 높은 수출 비중을 보여주었으며 수출액 상승률은 아시아, 북미, 유럽이 상대적으로 높게 나타났고 전윌대비 변동률은 아시아와 북미가 안정된 움직임을 보여주었다. 이 연구를 통해 우리의 수출액을 증가시키기 위해서는 아시아, 북미, 유럽으로의 수출 향상에 많은 관심을 보여야 할 것이다. 특히 50%가 넘는 아시아 즉, 중국, 일본, 베트남, 홍콩, 대만, 인도 등으로 수출 향상과 수출전략 방안이 필요해 보인다. 아직은 수출 비중이 크지 않지만 향후 중남미, 중동, 아프리카 등의 신시장 개척에도 많은 관심을 가지고 수출향상방안이 체계적으로 진행되기를 기대해 본다.

The concept of Chang Po-Go phenomenon is put forward and discussed in this paper from the point of view of international rationships in north-east Asia. Superfically, Chang Po-Go phenomenon showed trade prosperity on north-east Asia seas, but he nature of the phenomenon lies in the rising and strengthening of korea sea power. As works of the combination of general environment and individual heroism Chang Po-Go phenomenon can bring us some enlightenment on reform and open policy.

A gauge-adjustable system can be used for the fast and safe transportation in the railways with different gauges instead of transshipment or bogie-changing. The system will be necessary to connect the trans-Korean railway with the transcontinental railway effectively. In this paper, the technical requirements for the gauge-adjustable system used for the north-east asia network were studied and the conceptual design of the system was performed. For the purpose, the specification was made and the QFD and TRIZ methods are used.

In this paper, the cooperative research on the biodiversity conservation in North-East Asia is introduced. This research was initiated by National Institute of Biological Resources (NIBR) in 2012. The bilateral MOU and following MOA had been signed between NIBR and National University of Mongolia (NUM) in 2012, whereas those had been signed between NIBR and Institute of Zoology, Chinese Academy of Science (IOZ, CAS) in 2013. Details of the cooperative research based on those were presented.

Since the solar radiation is the main input for sizing any solar photovoltaic system, it will be necessary to understand and evaluate the solar radiation data. The works presented here is the analysis of solar radiation data for East-North Asia areas. The data utilized in the analysis consist of the global radiation on horizontal surface, measured at 2 different stations during 3 years for the period from 2002 to 2004 and estimated using satellite at 27 different stations over the China and Mongolia. Also the measured data has been collected at 16 different stations all of the South Korea and estimated using satellite at 12 different stations over the North Korea from 1982 to 2005. The Result of analysis shows that the annual-average daily global radiation on the horizontal surface is $3.57\;MJ/m^2$. We conclude, based on the analysis, that East-North Asia areas have sufficient solar energy resources for the photovoltaic power generation system.

The ACE Engineering, Inc. (ACE) of Seoul, Korea and The Energy Systems Institute (SEI) of Irkutsk, Russia has extensively studied the formation of an interconnected electric power systems throughout the North Eastern Asia Region(NEAR). The region encompasses East Siberia (ESR), Far East of Russia(FER), North East China(NEC), Mongolia(MON), North Korea(NKOR), South Korea(SKOR). Although geographically adjacent to each other, these countries and territories have different levels and rates of economic development, possess different reserves of energy resources which complement each other and hence, can interact to their mutual benefits. This Project is called Peace Network Project (PNP) because it seems to contribute for development of power economy and clean environment. In a word, the PEACE Network is expected to serve as "Power Economy And Clean Environment Network" and to promote the international cooperation. to expedite the peaceful reunification of North & South Korea and to revive the Korean culture in the North, and eventually contribute to the human prosperity.

Transportation routes by land like a human being blood vessel should exist for economic and trade exchange in Northeast Asia. Thinking from this point of view. I believe that TSR(Trans Siberian Railroad) and TCR(Trans Chinese Railroad). which will be connected with I would like to talk about .not only the effects of various international railroads and their connections but also economic activation TKR(Trans Korean Railroad). can play important roles. In this study, and effects in Northeast Asia which will be resulted from various international railroads construction. I tried to figure out comparative superiority and comparative advantage of the trade structure and industries in South and North Korea to find out the possibility of economic unification in East Asia. especial1y in Northeast Asia. This study also includes the effort to find out how trade exchange between South and North Korea can be expanded as a result of being a member of East Asia economic zone.

The sudden stratospheric warming (SSW), which is characterized by an abrupt increase of polar stratospheric temperature by several tens of degrees in a week, has been known to affect tropospheric weather and climate on sub-seasonal time scale in the boreal winter. Such downward coupling has been often examined in North Atlantic and Europe, but rarely examined in East Asia. In this study, by applying the two definitions of SSW to the reanalysis data, the possible impacts of the SSW events on the surface air temperature (SAT) and tropospheric circulation in East Asia are analyzed. It is found that Eurasian continent, including Siberia and the Northeast Asia, tends to experience anomalously cold SAT for up to sixty days after the SSW events. The resulting SAT anomalies largely resemble those associated with negative Artic Oscillation. However, over East Asia, SSW-related SAT change is weak and not statistically significant. Only during the extreme SSW events when the downward coupling between the stratosphere and troposphere is strong, East Asia exhibits significantly cold SAT anomalies. This relationship is presented by grouping SSW events into those followed by cold SAT anomalies over East Asia and those by warm anomalies for varying threshold values of the SSW events.
