China's 'One Belt One Road' initiative has had a profound impact on China's relationship with Central Asia, which shares borders at North-western region. Central Asia plays an important role in securing the export market of Chinese products, supply of raw materials, and transportation route to Europe. The inland port is of significance to facilitate the development of logistics, trade and industry in the surrounding areas by enabling the distribution and import and export clearance in the region by performing the role of the seaport on the hinterland. The purpose of this study is to analyze the effect of the development of inland ports in central and western China on the geopolitical relationship between China and Central Asia. To this end, we analyze the status of inland port development in China's Midwest by employing the SWOT-PEST analysis method to analyze the current status as well as prospects of trade, investment and transportation routes with Central Asia in terms of geopolitics. As a result of the analysis, the relations between China and Central Asian Countries are becoming more politically and economically close, but it has brought about serious challenges by domestic and foreign environmental changes. Therefore, the development of the inland ports in central and western China are determined by the geopolitical relations under 'One Belt One Road' initiative between China and Central Asia, while the development of the inland port is also expected to serve as a catalyst for the development of both regions.

This study analyzed the change in tropical cyclone (TC) activity according to the fluctuation in July-to-September average North Pacific Oscillation index (NPOI) and its underlying large-scale environment during the last 37 years from 1977 to 2013. For this purpose, seven years with highest index NPOI value (positive NPOI phase) and another seven years with lowest NPOI index value (negative NPOI phase) among the 37 years were selected as sample after excluding the ENSO years. During the positive NPOI phase, TCs were created in the east of tropical and subtropical western North Pacific and moved to the west from the Philippines toward the southern region in China or toward far eastern sea of Japan. Meanwhile, during the negative NPOI phase, TCs tended to proceed to the north toward Korea or Japan passing East China Sea from the eastern sea of the Philippines. As a result, also in the TC recurvature, TCs in positive NPOI phase showed a tendency of recurving toward more eastern direction compared to TCs in negative NPOI phase. Hence, TC intensity was stronger in negative NPOI phase which allowed more time for obtaining energy from the ocean.

본 논문은 주체와 대상 간의 상대적 위치를 인식할 수 있도록 해준 위치성 개념이 예외 공간으로서의 접경지역의 공간성 파악에 활용될 수 있다고 주장하고자 한다. 접경지역은 거리상으로 국경선을 사이에 두고 맞은편 국가와 가까이 위치하고 있지만 국경을 둘러싼 지정학적, 지경학적 변화에 따라 갑작스러운 단절과 개방이 나타나는 다중적인 공간이기 때문에 위치성의 전환이란 측면에서 파악하기에 적절하다. 본 논문이 접경지역을 위치성 전환의 관점에서 재개념화함으로써 기대하는 점은 다음과 같다. (1) 접경지역의 변화 가능성을 로컬에 기반을 둔 내적 조건뿐만 아니라 보다 넓은 맥락과 정세 속에서 파악할 수 있다. (2) 접경지역의 발전 궤적을 다양한 힘들 간의 아쌍블라주를 통해서 파악할 수 있다. (3) 지경학과 지정학 간의 역동적 관계를 통해서 접경지역의 위치성 전환을 파악할 수 있다. 특히 위치성은 기존 공간과 시간, 공간성에 대한 논의를 관계론적/변증법적, 사회-공간론적, 권력-위상학적 측면에서 새롭게 확장시켜준다는 점에서 의미가 있다. 마지막으로 본 논문은 위치성 전환을 통해서 북중 접경지역의 예외적 성격을 파악하였다. 북중 접경지역은 한반도의 지정학적 안보 불안이라는 '예외 상태'가 상례화되고 있는 상황 속에서 이를 뒷받침하는 다양한 지경학적 논리가 작동하면서 다른 지역과 구분되는 예외적인 성격을 창출한 것으로 이해된다.

장마포기에는 적도에서 동지나 지역은 주로 대류에 의한 강수가 우세했으며, 대다수의 수증기는 인도 몬순지역에서 이류되어 온 수증기임을 안 수 있었다. 장마기에는 한반도 지역은 convection에 의한 강수는 미소하나 microphysics에 의한 강수가 지배적이었다. 이 때 수증기의 근원(강수량)은 인도 몬순지역에서 이류되어 온 수증기이다. 비장마기에 우리나라 및 대다수의 지역은 microphysics에 의한 강수가 지배적이었다. 또한 태풍의 북상으로 인한 대량의 수증기의 이류이다. 수증기의 대부분은 Rossby wave의 복동방향 전파에 기인한다.

We measured the fugacity of $CO_2$ $(fCO_2)$, temperature, salinity, nutrients and chlorophyll a in the surface water of the western North Pacific $(4^{\circ}30'{\sim}33^{\circ}10'N,\;144^{\circ}20'{\sim}127^{\circ}35'E)$ in September 2002. There were zonally several major currents which have characteristics of specific temperature and salinity (NECC, North Equatorial Counter Current; NEC, North Equatorial Current; Kuroshio etc.). Surface $fCO_2$ distribution was clearly distinguished into two groups, tropical and subtropical areas of which boundary was $20^{\circ}N$. In the tropical Int surface $fCO_2$ was mainly controlled by temperature, while in the subtropical area, surface $fCO_2$ was dependent on total inorganic carbon contents. Air-sea $CO_2$ flux showed a large spatial variation, with a range of $-0.69{\sim}0.79 mmole\;m^{-2}day^{-1}$. In the area of AE (Anticyclonic Eddy), SM(Southern Mixed region) and NM (Northern Mixed region), the ocean acted as a weak source of $CO_2$ $(0.6{\sim}0.79 mmole\; m^{-2}day^{-1})$. In NECC, NEC, Kuroshio and ECS (East China Sea), however, the fluxes were estimated to be $-0.3mmole\; m^{-2}day^{-1})$ for the first three regions and $-1.2mmole\; m^{-2}day^{-1})$ for ECS respectively, indicating that these areas acted as sinks of $CO_2$. The average air-sea flux in the entire study area was $0.15mmole\;m^{-2}day^{-1})$, implying that the western North Pacific was a weak source of $CO_2$ during the study period.

The development of information technology got rid of much restriction on time and space, inviting earlier knowledge based society. The growing e-commerce based on internet alters the existing way of management in business groups and countries to one based on e-business. Especially, neighboring Far-East Asia countries are on the way of increasing their interest and efforts on e-commerce. Also they continue to give support to e-commerce and explore the way to North-East Asia e-Hub, on the government level. Against this backdrop, this study tried to review the current status and supporting system of e-commerce in 6 North-East Asia countries(South Korea, China, Japan, Taiwan, Hong Kong and Singapore), as a preliminary work for building the base of e-commerce and spurring the economic cooperation through e-commerce in North-East Asia region. I expect that this review would do the role of basic material for exploring and prospecting Korea's possibility as the North-East Asia e-Hub.

이 연구는 동북아 지역의 국제복합운송의 현황과 전망을 분석하고 지역내 통과운송 협약의 필요성과 추진방안을 검토하였다. 이 연구에 따르면, 동북아 국가들간 교역확대와 경제협력 긴밀화에 따라 국제복합운송과 통과운송이 지역내 혹은 지역과 타 경제권간 활발하게 전개되어 왔으며, 향후에는 더욱 확산될 것으로 보인다. 동북아 주요 국가들인 중국, 러시아 등은 육상운송에서 국제복합운송 경로를 주도하기 위해, 내륙 국가들과 통과운송 협약을 체결하는 등 역내 물류협력을 강화하여 왔다. 이 연구는 동북아 국가들의 국제복합운송과 통과운송에 대한 수요증가, 물류기기와 장비의 확보와 운영, 새로이 부각되는 환경문제 등을 동북아 국가들이 공동적으로 대처할 것을 지적하는 한편 유엔해양법 협약에 기초한 통과운송에 대한 지역적 국제협약의 필요성을 제시한다.

The long-term variability of sea surface temperature in the East China Sea was reviewed based mainly on published literatures. Though the quantitative results are not the same, it is generally shown that sea surface temperature is increasing especially in recent years with the rate of increase about $0.03^{\circ}C$/year. Other meaningful results presented in the literatures is that the difference of water properties between layers upper and lower than the thermocline in summer shows an increasing trend both in temperature and salinity, suggesting that the stratification has been intensified. As a mechanism by which to evaluate the wintertime warming trend in the region, the weakening of wind strength, which is related to the variation of sea level pressure and atmospheric circulation in the western North Pacific and northern Asian continent, is suggested in the most of related studies.

This study was carried out to understand the regional contribution of Particulate Matter (PM) emissions from East Asia ($82^{\circ}{\sim}149^{\circ}E$, $18^{\circ}{\sim}53^{\circ}N$) to Seoul during high concentration period in February 2014. The Community Multi-scale Air Quality (CMAQ) version 5.0.2 with Decoupled Direct Method (DDM) was used to analyze levels of contributions over Seoul. In order to validate model performance of the CMAQ, predicted PM and its chemical species concentrations were compared to observations in China and Seoul. Model predictions could depict the daily and hourly variations of observed PM. The calculated PM concentrations, however, had a tendency of underestimation. The discrepancies are due to uncertainties of meteorological data, emission inventories and CMAQ model itself. The high PM concentration in Seoul was induced by stationary anticyclone over the West Coast of Korea during 24 to 27 February. The DDM in CMAQ was used to analyze the contributions of emissions from East Asia on Seoul during this PM episode. $PM_{10}$ concentration in Seoul is contributed by 39.77%~53.19% from China industrial and urban region, 15.37%~37.10% from South Korea, and 9.03%~18.05% North Korea. These indicate that $PM_{10}$ concentrations in Seoul during the episode period are dominated by long-range transport from China region as well as domestic sources. It was also found that the largest contribution region in China were Shandong peninsula during the PM event period.

Balassian Approach of regional economic integration has been mainly aimed at improving conditions for regional trade since 1960s. After the financial crises of the late 1990s, however, the theoretical approach to regional integration will have to be a different one as regionalism have to offer enhanced protection against crises. The aim of this paper, above all, is to provide a theoretical framework for the emerging new monetary regionalism. Regions that wish to strengthen their co-operation in monetary and financial affairs today have the option of monetary regionalism without trade agreement. East Asian region will become an increasingly important domain within which to explore enhanced protection against financial crises. And as Korea seems to play a crucial role in building regional integration among ASEAN＋3(Korea, China and Japan) countries, alternative policy for Korean economy to be the North-east Asian Economic Base need to be schemed on the basis of Balassian as well as monetary regionalism.
