  • Due to the global-convection currents, transboundary transport of air pollutants is widely observed in many regions of the world. This study was carried out to investigate the pattern of long-range transport of air pollutants in North East Asia, especially the impact of air pollutants originated in China and Japan on the air quality in Korea. From the meteorological data at the 850 mb surface from May 1986 through April 1987 at 54 obsevation stations in the North East Asia region, the backward and forward trajectories were calculated using interpolation method. And the contributions of pollution sources in neighbor countries to the air quality in Korea were analyzed. It was concluded that air pollution in China had a great influence on the air quality in Korea throughout the year : it could be transported to Korea just within 2 or 3 days most of the time. The trajectory analysis showed that pollution sources in Beijing. Liaoning Province, and Shandong Province, the most heavily industrialized areas in China., were the most influential for the air quality in Korea except for summer season. Durnig summer season, the air pollution in Shanhai and Japan could have moer influence on Korea. Such transboundary transport of air pollutants necessitate international cowork and cooperation in the region of North East Asia.

  • Many countries in the North East Asia are competing with each other in order to become a centre of international logistics activities. The competition to become a hub port in Far East region is now fierce. The anticipated investments on improving port facilities and attracting the mega carriers are immense for all the ports in the region and the extent of the effort could cripple the local ports and region's economy given the limited financial resources. It is, however, impossible to avoid the disastrous possibility that the massive investments could be channeled into the port, which will never become a hub port, as no port is ready to currently admit defeat and settle as a small regional port. In an attempt to minimise such disastrous waste of resources, ports need to verify the eligibility of their own. This paper tests a system dynamics model using the Port of Busan to understand and illustrate the principle guideline of investment decision making for ports.

  • 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 port environment is rapidly changing in North-East Asia. Containerships are getting larger and faster and major shipping companies are converting to Hub & Spoke port networks on the transport systems. Therefore, the main ports in North-East Asia are intensively competing with each other for hub port. In terms of geopolitical position, locational conditions and external reputation of ports, Busan and Kwangyang ports have a comparative advantage in comparison with main ports in other countries. But in terms of weight of transshipment cargos in total container cargos, the quality of infrastructure in ports, the environment of logistics service and the cost of, using ports, Busan and Kwangyang ports have a comparative disadvantage. For the growth into hub port in North-East Asia, it is necessary that Busan and Kwangyang ports improve their weakness. Besides It is necessary to develope ports and hinterland quickly, offer uniformity of foreign investment laws and incentive systems.

  • This paper presents the effects and the regional power distribution of an increase or a decrease of a power reserve by load flow calculations under seasonal load patterns of each country for the future power shortages faced by the metropolitan areas or by the southeastern area of the South Korea in North-East Asia. In these connections, the types of a power transmission for interconnection consist of the 765kV HVAC and the HVDC. 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. The power flow map is drawn from data simulated and the comparative study is done. In this 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 Asia countries.

  • 본 연구는 최근까지 이루어진 공항의 집중도 및 항공 유동성 자료를 바탕으로 한 선행연구를 고찰하고, 항공 및 공항의 환경변화에 따라 변화되고 있는 아시아 주요공항의 화물 물동량 구조를 파악하였다. 또한, 아시아 지역에서의 화물 전이 현상을 분석하여, 경쟁공항들의 경쟁수준을 파악하여 향후 전략적 시사점을 제시하는 것을 본 연구의 목적으로 하였다. 현재 동북아 권역의 과점화는 꾸준히 약화되고 있으나 이는 중국공항의 성장에 따른 결과이며 이 지역에서의 푸동공항은 지속적인 물동량 확대는 새로운 과점화 증대 현상도 일어날 수 있다는 것을 시사한다. 또한, 2000년부터 2012년까지 항공화물 변이 효과분석 결과에 의하면 인천공항의 항공화물은 약 42만 톤이, 나리타공항은 약 128만 톤이 동북아 권역의 다른 공항으로 전이된 것으로 분석되었다. 이는 일부가 직접경쟁이 가능한 푸동공항으로 전이된 것으로 판단할 수 있어 향후 전이가 지속적으로 창출되는 원인과 이유에 대한 추후 연구도 필요한 것으로 판단된다.

  • This study is designed to propose the ways of the multilateral cooperation system for effective management of fisheries resources in the various overlapping zones established by bilateral fisheries agreements between Korea, China and Japan in North East Asia as semi-enclosed sea. It is necessary to build multilateral fisheries cooperation between Korea, China and Japan in North East Asia because conservation & management of transboundary fish stocks could not be guaranted effectively by the management of fisheries resources in the area where piled up the current-fishing-pattern zone, as white zone and the various grey zone as middle zone, and the interim measures zone of bilateral fisheries agreements between Korea, China and Japan are piled up. Fisheries management in Korea, China and Japan by the bilateral fisheries agreements in North East Asia is faced with difficulties manage fisheries resources. International relationship on fisheries is maintained by bilateral fisheries agreements based on UNCLOS. However fisheries resources are over-exploited and the recovery of the fisheries resources is very slow because proper conservation and management of transboundary fish stocks which article 63(1) of UNCLOS defines have not prepared yet. Thus close cooperation among the coastal States for a proper conservation and management of transboundary fish stocks is necessary. Since the transboundary fish migrate within the EEZs of two or more coastal States, there is a need to manage the fish stocks in the region between Korea, China and Japan through a multi-lateral mechanism at ccircumference area of the current-fishing-pattern zone as white zone. Coastal States must guarantee sustainable maintenance of transboundary fish stocks through the regional cooperation for a proper conservation & management because one coastal State alone could not guarantee conservation and management of fish stocks. Thus there is a need to build multilateral fisheries cooperation between Korea, China and Japan in North East Asia. There are many successful instances including the Barents' sea for a proper conservation & management of transboundary fish stocks. The Barents' sea is one of the best research object to study the regional cooperation for a conservation & management of transboundary fish stocks in North East Asia. In conclusion, it is necessary to build a multilateral fisheries cooperation system between Korea, China and Japan in North East Asia to conserve and manage transboundary fish stocks effectively. It seems desirable that the range of the area to conserve and manage fish stocks should may be any partial area in the current-fishing-pattern zone and interim measures zone between Korea and China, Jeju middle zone between Korea and Japan, interim measures zone of bilateral fisheries agreements between China and Japan.

  • The changes in the teleconnection associated with El Nin?o-Southern Oscillation (ENSO) over the East Asia and North Pacific under greenhouse warming are analyzed herein by comparing the Historical run (1970/1971~1999/2000) and the Representative Concentration Pathway (RCP) 4.5 run with 31 climate models, participated in the Coupled Model Intercomparison Project Phase 5 (CMIP5). It is found that CMIP5 models have diverse systematic errors in simulating the ENSO teleconnection pattern from model to model. Therefore, we select 21 models based on the models' performance in simulating teleconnection pattern in the present climate. It is shown that CMIP5 models tend to project an overall weaker teleconnection pattern associated with ENSO over East Asia in the future climate than that in the present climate. It can be also noted that the cyclonic flow over the North Pacific is weakened and shifted eastward. However, uncertainties for the ENSO teleconnection changes still exist, suggesting that much consistent agreements on this future teleconnections associated with ENSO should be taken in a further study.

  • 한국 정부는 액화 천연가스를 대체하는 에너지원으로서 러시아의 파이프라인 천연가스 도입을 1990년대 이후부터 지속적으로 모색해오고 있다. 이러한 동북아 에너지 협력에 대한 논의가 현실 정치뿐만 아니라 학술적인 차원에서도 다양하게 진행되고 있지만, 기존의 선행연구들은 협력의 당위성만을 제시하고 있을 뿐이지 이론적 분석틀이 미약하다는 한계를 지니고 있다. 이에 본 논문에서는 경제통합론이라는 이론적 자원을 바탕으로 에너지협력의 동기 조건 단계를 분석하고자 한다. 연구 결과 동북아 천연가스 협력과 관련해서는 경제적 동기만이 유일하기는 하지만, 실질적인 기대이익뿐만 아니라 경제구조의 보완성과 정책목표의 수렴성이라는 조건들이 갖추어진 것으로 파악되었다. 결론적으로 동북아에서 높은 수준의 에너지 협력은 어렵겠지만 특혜무역협정 수준의 초보적인 천연가스 협력이 가능하다는 전망이 제시될 수 있었다.
