This study revisits the meaning of energy security by examining the oil market supply and demand conditions of petroleum products and refinery capacity of three Northeast Asian countries(Korea, China, Japan). In 2006, 10.6 million bid of excess demand occurred and is expected to be 15~22 million bid by the year 2030 in this regional oil market. Different oil demand is caused mainly by the different demands for various petroleum products based on each country's economic structures. If the demands are ranked according to their petroleum products, Chinese case shows gasoil > gasoline > fuel oil> LPG > naphtha > Kero/jet and Japanese case shows gasoil > gasoline> naphtha> Kero/jet > fuel oil > LPG, while Korean case shows naphtha> gas oil > fuel oil > LPG > Kero/jet > gasoline, respectively. Total CDU(Crude Distillation Unit) capacity of three northeast asian countries also have been examined in this respect. This study points out the importance of the information on oil demand and supply, on petroleum products and refinery capacities of the three Northeast Asian countries to enhance the security of the oil market in this region.

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.

China is expected to experience rapid increase in container traffic due to the joining to WTO and the fast economic growth. However, logistics-related infrastructure such as sea port is very poor and the capacity is lagging far behind the demand, resulting in transferring around 70% of import and export cargo volume at ports in adjoining countries such as Korea, Taiwan, Hong Kong and Japan. Recently, China announced a huge project of developing an offshore port consisting of 52 berths, 30km away from Shanghai with a connecting bridge. As such plan seems to have a significant impact on the port of Pusan which tries to be a Hub port in Far East Asia, we need to scrutinize the plan. This paper, therefore, tries to examine Shanghai New Port Plan, to evaluate the feasibility and potential competitiveness, and to analyze the impact on Pusan port. For this, we review the situation of major container ports in China and the flow pattern of container traffic to and from Pusan port. We then examine the feasibility of the proposed offshore port with respect to demand and supply for container terminal, weather condition, hinterland connection and resource of investment.

Since the signing of the Korea-Europe Free Trade Agreement, the volume of trade transactions between South Korea and Europe has increased. The traditional single-mode transport system has been transformed into an intermodal transport system using two or more modes of transport. In addition, the conventional sea and air transport routes have been restricted, leading to a decline in Korean exports to Europe, and the rail transport mode is becoming mainstream in the market due to the influence of COVID-19. This paper focuses on the China-Railway Express to explore a new intermodal transport route from Korea to Europe. First, the fuzzy analytic hierarchy process (AHP) is used to evaluate the factor weights when selecting intermodal transport routes from Korea to Europe. Then, the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method is used to rank three alternatives. The results show that among the four factors (total cost, total time, transportation capability, and service reliability), the total cost is the most significant factor, followed by the total time, service reliability, and transportation capability. Furthermore, the alternative route 1 (Incheon-Dalian-Manchuria-Hamburg) is preferred.

The aim of this study is to analyze the efficiency of major ports in Northeast Asia such as Korea, China and Japan. For the empirical analysis, we tried to apply the data envelopment analysis (DEA), which is an efficiency evaluation model based on mathematical programming theory, and we also established a model to Northeast Asian ports. In our opinion, DEA analysis which involves multiple inputs as well as multiple outputs in its efficiency valuation makes analysis more suitable for port efficiency measurement because ports produce a number of different outputs. In this paper, we attempted to analyze the relative efficiency of 27 ports (5 Korean ports, 13 Chinese ports, 9 Japanese ports) through DEA-CCR, DEA-BCC models. According to the result, Chinese ports are relatively efficient than Korean and Japanese ports. The result of the analysis shows that 7 Chinese ports are efficient in DEA-CCR model in 2009, but in DEA-BCC model 8 Chinese ports and 1 Koran port are efficient. Most of inefficient ports have a value closed to 1 in efficiency for scale, it means that the reason of inefficiency is caused from the technical aspect. Furthermore, we also verified that there exists excess of input in Korean and Japanese ports than Chinese ports.

Loess (黃土)는 지구의 10 ％를 차지하고 있으며, 황사 (黃砂)폭풍으로 장거리이동이 가능하여 동아시아까지 이동할 수 있다 (Zhang De'er, 1982). 황사현상은 최근 동북아시아에서 급속한 산업발달과 인구증가, 그리고 생활수준의 향상에 따라 많은 양의 오염물질이 대기로 방출되고 있다. 특히 중국이 이 지역에서 배출되는 대기오염물질의 대부분을 배출하고 있다 (국립환경 연구원, 1998).(중략)

한미 FTA 타결은 수출에 큰 도움이 될 것으로 전망되고 있다. 세계 1위의 경제 대국 미국과의 자유무역협정(FTA)이 타결됨으로써 우리나라는 개국에 버금가는 엄청난 변화를 맞게 될 것으로 예상된다. 지난 19세기말 강화도 조약으로 조선이 개화기를 맞았듯이 이번 FTA 타결로 우리는 개방경제의 닻을 본격 올리게 되었다. 특히 중국과 일본에 끼어 샌드위치 신세를 면치 못하던 우리가 모처럼 새 성장 동력을 얻어 동북아 지역에서 기선을 잡는 계기를 마련한 것으로 평가되고 있다. 해운 및 항만의 경우 양국간 교역량 증가로 해운 및 항만에 긍정적인 영향을 가져다 줄 것으로 분석되고 있다. 다음은 한미 FTA 체결에 따른 부문별 파급여파와 변화 등을 요약정리한 것이다.

5G 이동통신은 4세대 LTE보다 전송속도는 270배 빠르고, 지연시간은 1/30에 불과 할 정도로 빠른 속도와 연결성을 제공하기 때문에 가상현실, 증강현실, 자율주행차 등의 새로운 서비스를 구현할 수 있다. 5G 이동통신이 미래 유망 서비스로 부각되자 이동통신사들은 노키아, 에릭슨, 화웨이, 삼성전자 등 글로벌 장비업체들과 제휴하여 2019~2020년 상용화를 목표로 5G 기술개발에 박차를 가하고 있다. 일본의 NTT도코모, 중국의 차이나모바일, 한국의 KT, SK텔레콤 등 동북아 3국의 통신사업자들이 정부 전략과 공조하면서 가장 앞서 나가고 있다.

기원전 37년 부여족의 일족인 고주몽이 건국한 고고려는 약 700년간 만주와 북만주를 무대로 하여 활약한 강대한 나라이며 한민족사상 가장 중요한 위치에 있었다. 부여족은 4000년이전에 중국의 동북부에서 만주에 이동한 문화민족이며 한나라에 의하면 그네들은 언제나 자기민족의 고도로 발달된 문화수준을 자랑하였고 주위의 타민족을 남만 북적 서융 동이라고 칭하여 야만인 취급을 하였음에도 불구하고 부여족만은 문화수준이 높은 민족이라고 하여 동등의 대우를 아끼지 않았다. 맥(貊)족에 대하여서는 춘추전국시대의 장자를 위시하여 소위 한서 남사 북사 제서 수서 구당서 당서등 고문헌의 어느 것에나 문화를 가진 민족으로써 소분되어 있었다. 과연 부여족은 만주지방에 산재되어 있는 수많은 민족중의 선각자이며 특히 고구려는 만주 및 한반도에 거주하고 있는 모든나라의 중심이 되었다.

황사의 발생과 이동은 대기미량물질의 장거리이동 현상 가운데 우리에게 가장 익숙한 것일 것이다. 우리나라는 동북아시아의 동쪽에 위치한 지역으로, 사계절 중 여름을 제외한 때의 주풍향이 서풍인 지역이다. 특히, 봄철에는 편서풍의 영향이 크다. 따라서 우리나라는 봄에 몽골이나 중국북부의 사막이나 황토지대에서 불어오는 황사의 영향을 불가피하게 받게 된다. (중략)
