Atmospheric environment in Korea is influenced by outside, especially China. The concentrations of air pollutants in China have showed decreasing trends since 2000. However, these concentration levels in China are still higher than other developed countries. The Chinese Government has tried several measures to control the air pollution. In this study, the details of the amendments and smog reduction strategies in China, especially for Beijing are reviewed and the strategies for Korean side to promote cooperation in Northeast Asia are suggested and discussed. The Chinese State Council amended the Environmental Protection Provisions and Clean Air Act and announced The Action Plan for Air Pollution Control (2013-2017), focusing on three key regions, Beijing-Tianjin-Hebei area (Jing-Jin-Ji), Yangtze River Delta (YRD) and Pearl River Delta (PRD). These policy actions and plan are mainly for the reducing coal usage and emissions from vehicles. It is suggested that, Korea should actively promote multi-national cooperation in the region to take an initiative role in environmental areas.

최근 정부의 신북방정책 추진에 따라 수자원분야에서는 동북아지역 국제 공유하천을 중심의 물 정보 및 연구협력 기회 확보와 지정학적 특성을 고려한 지역 현안해결 중심의 연구가 재조명 되고 있다. 두만강은 이러한 동북아의 중심에 위치하고 있으며, 중국, 북한, 러이사의 국경을 따라 흐르며 지역 수자원의 대부분을 공급하는 국제하천이다. 또한, 지난 2018년 5월에는 하구유역이 람사르(Ramsar) 습지로 승인됨에 따라 철새 등을 포함한 생태가치의 중요성도 크게 증가하였다. 하지만 이 지역은 유역의 지정학적 민감성과 접근이 제한된 관측 정보들로 인해 그 수자원·환경 효용성을 정확하게 파악할 수 없을 뿐만 아니라, 최근 기후변화에 따른 영향으로 홍수, 가뭄 등의 수재해와 수질오염 등의 문제가 발생하고 있어 가용한 기술기반의 직·간접적 접근을 통한 장기수문 및 환경변화 등에 대한 분석과 관리방안 수립 등의 연구가 필요하다. 본 연구에서는 이러한 미계측 두만강 유역을 대상으로 우선, 가용한 위성자료 및 광역지표모형(MERRA-2) 기반 NASA POWER(Prediction of Worldwide Energy Resource) 수문기상 자료와 SWAT(Soil and Water Assessment Tool) 모형을 활용하여 장기 수문영향을 평가하고자 한다. SWAT 모형은 전 지구적으로 활용 가능한 격자 해상도 약 30m의 위성기반 수치표고모형(DEM), 광역 토양도, 지역 토지이용도 자료를 활용하여 두만강 유역을 전체 19개 소유역 및 18개 하도, 138개 HRUs의 수문분석 단위로 구축하였으며, 모의는 미국 NOAA NCDC(National Climate Data Center) 및 중국 CMDC(China Meteorological Data Service Center)의 주요 관측지점에서 선별한 총 13개소의 위치에 대해 재분석된 기후/기상자료들(NASA POWER 강수, 기온, 풍속, 상대습도 및 일사량)을 적용, 1990년에서 2019년까지의 30개년도 연속자료를 구축활용 하였다. 한편, 모형의 검·보정은 앞서 언급한 관측 자료의 부재로 과거 문헌 등을 통해 파악할 수 있는 연 단위 수자원 총량 등을 활용해 진행코자한다. 아울러, 향후는 최근 활용 가능한 장기 위성관측 강수량을 적용, 재분석 자료 결과와의 비교를 통해 상호 분석 오류를 줄여나갈 수 있을 것으로도 판단된다.

In global, there is an active movement to reduce the green house gas. Allowance and carbon tax are the one of effective alternatives to mitigate green gas effect. In addition, the clean development machinism(CDM) can be applied between the ANNEX 1 and developing countries. It could be an one good solution to reduce the GHG. In the Northern Asia, the CDM can be the one of the possible solution to reduce the GHG because the Japan has a responsibility to reduce GHG and the China and Korea have a room to supply CDM credit. It is suffice to say that if these three countries decide to collaborate, the new international carbon market can be established that can be the similar form of EU-ETS. It is clear that few barriers must be removed to launched such new form of carbon market. Protection of domestic technology, excessive financial request of business opportunities by CDM, and irrational needs of carbon credit that created by CDM, listed constraints define as an one single word, the national selfishness. Once it is cleared, there is high possibility that the Northern Asia CDM trading system can be launched.

This study was conducted to compare the changes in the forest resources and the process of establishment and characteristics of the Forest Law in five Northeast Asian Countries, who share the Chinese culture as a common background. The effect of Forest Law on forest resources of each countries is also compared. This study shows that the forest management scheme and the modernistic forest law in the five Northeast Countries were influenced by Japan around the early 20th century. The Forest Laws of the five countries were reestablished after the end of World War II, and now the five countries have their own Forest Law. At present, the five countries are depending on the import of foreign timber for timber supply because of the shortage of domestic timber resources. The Forest Laws of the five countries have a lot of similarities reflecting same cultural background, whereas there are differences originated from social and economic discrepancies. Currently R.O.K. is worst in forest resources compared to the other countries. The Forest Law of R.O.K. has too many articles, which has little direct relationship with forest resources management. Therefore it is recommended to consolidate the law system in the field of forest and forestry in R.O.K. including the amendment of Forest Law directing to sustainable forest and maintaining the efficiency of forest resources management.

The construction of Incheon International Airport(IIA) was planned in order to meet the national air transport demand which has been rapidly increased, and to be a major hub airport in Northeast Asia. However, it is inevitable to compete with Japanese airports because Japanese government also planned to expand greatly the airport capacity in Tokyo area and Kansai Airport in Osaka area. Since a hub airport should have convenient connecting flights to spoke cities, it is required for IIA to have plenty of short-haul flights to the cities around Seoul, for example, to the cities in East China, Japan and other East Asian countries. IIA authority and Korean national air carriers should coordinate to develop air transport demand for short-haul international route and establish efficient hub-spoke flight schedules. This would be a essential precondition to function as a hinterland hub in Northeast Asia. Reflecting the geographical position, the function as a hourglass hub could be possible, if IIA is utilised by major airlines as a bridge to connect passengers between cities in Southeast Asia and 'cities in North America. To be a successful hourglass hub, the Korean national carriers must try to engage in the joint operations or the alliances with the major airlines of Southeastern countries or North American countries. All of these could be accomplished through the cooperation among government, airport and national air carriers.

China has been tried to make our former territory named "Guryubuel" as their territory and history using the "Northeast Expanding Project" and other territory expanding projects. This study aimed to make a correspond measure to the cause, purpose and statues on the Northeast Expanding Project of China, to help restoration of Korean territory. For this purpose, it was reviewed the detail about Territory Projects of China. This study included not only the "Northeast Expanding Project" but also the Dandae Project, Tamwon Project and the theory of 'Yoha Civilization' to reveal the project's cause, purpose and detail to analysis the issues and to make a countermeasure. China has been distorted our cture and history on purpose for the territory expanding project. Hence, this study has distinction from the previous approach on the China's territory projects since it has been focused on dilemma of cultural and historical distortion by some Chinese. This study pointed out the distortion of the history and culture of China, as well as Korean mistakes to interpret the China's claim into our own way. It is emphasized that progressive response of Korean government is very important to protect our territory against the Chinese territory expanding projects.

Recently, the importance of the northeast economies including Russia has been growing, and according to the Eurasian initiative policy, the enhancement of transportation, logistics and connectivity between the northeast Asian countries is emerging as one of the challenges for future growth. However, due to the different vehicle systems used in each country, the railway connections between countries are not operating smoothly. Especially, the couplers of the railway cars which pass through the countries of northeast Asia including Russia have different regulations, which render their shape and characteristics incompatible. In this study, we propose a method of interconnecting the AAR type coupler used in Korea and China and the CA-3 type coupler compatible with the Russian GOST standard, and verify that its structural safety conforms with each set of regulations. We analyze the possibilities offered by this method of interconnection by performing tests while developing materials satisfying the mechanical properties required for the freight coupler.

The purpose of this study is to outline the strategic implications of a structure analysis and trends of transferred air cargoes for the main airports of the North Asian region for 13 years from 2000 to 2012. To do so, it analyses the concentration levels using a Gini coefficient and Hirschmann Herfindahl index and represents the competitive positioning with regard to the main East Asian airports using the BCG framework and shift-share analysis. Currently, the concentration level is getting weaker in response to the emergence of Chinese airports in the north-east region. It is likely that the steady growth of air cargo of Shanghai airport (PVG) has caused the increase in concentration levels in the region. Seoul airport (ICN) may be directly in competition with PVG for air cargo in the region, giving consideration to reducing or maintaining an average increase ratio of air cargoes of ICN, NRT (Tokyo), and KIX (Osaka) for same period. In the same sense, the average increase in ratio for ICN for same period yields 1.3%, which is far behind the 6.2% and 5.2% of the north-east region and PVG respectively. Additionally, shift-share effect analysis indicates that ICN lost 422,180 tons in the north-east region during the same period, suggesting that transferred cargoes might have been forwarded to PVG.
