The role of container ports contributes greatly to international trade and national or regional economic development by supporting maritime transportation and occupies a central position in the supply chain connecting sea and land. The performance(traffic volume) of a port generally depends on geographic, economic, and operational factors etc. For the past several decades, container port volumes have grown with fluctuation. This study amis to analyze how global ports have undergone changes in terms of cargo volume by region, size and period. For the analysis, only the volumes of global top 100 ports were used. Shift-share analysis and BCG matrix analysis were employed as methodologies. According to the result of the analysis, the relative volatility of port traffic over the past 16 years as a whole was found to be limited. On the other hand, ports in China and Southeast and Southwest Asia, which are economically growing for the last decades, showed growing trends, while ports in Northeast Asia and Europe appeared to be in a stagnant or declining phase. It also shows that most of the global ports maintain limited changes in cargo volume because they are already positioned as central ports in the region. In addition, it can be seen that the global port volume has a close relationship with the change in the economic capability of the relevant region or country.

China has achieved rapid economic growth in the late 1970s with economic reform and open-door policy. China's economic growth began initially in the eastern coastal areas and from the 2000s expanded to the western and northeastern regions where the economy was relatively underdeveloped. In particular, in 2013 'One-Belt One Road' initiative proposed by Xi Jinping, the current General Secretary of the Communist Party of China is not only a key strategy for China's advancement into the world and also provides important opportunities for the development of these backward regions. Inland Port is the inland logistics hub and plays a crucial role in enhancing access to maritime ports as well as access to adjacent inland countries. Therefore, a number of inland ports have been developed and operated in order to enter into overseas markets and secure resources in the northeastern and western regions of China. This study aims to examine the role and development of inland port in 'One-Belt One Road' scheme. In conclusion, 'One-Belt One Road' will further increase the role of inland port, and in response, the development of inland port will play a pivotal role in one belt one road initiative. In this respect, Korean companies need to consider plans to participate in the development and operation of inland ports in China, which would provide opportunities to spread Northern markets including China, Russia, Central Asia, Eastern Europe.

Extracts of 33 medicinal herbs belonging to 28 different families used as precious resources in the Northeast Asia were tested for their antiviral activities against two major plant viruses. Twenty one methanol extracts from 19 different families were found to have a antiviral activity against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) when tested on indicator plants under greenhouse conditions. Most of these extracts have weak activities at the concentration used. But the methanol extracts of Phellinus linteus exhibited potent ($98.7{\pm}1.3%$) antiviral activity against TMV infection and also showed $97.2{\pm}2.2%$ activity against CMV infection. The methanol extracts of the gall of Rhus javanica also showed strong inhibitory efficacy over $98.7{\pm}1.1%$ against TMV or CMV infection. Further research is needed to elucidate the active constituents of these medicinal herbs which may be useful in the development of new and effective antiviral agent against plant viruses.

국내의 주요 물류기업들 중 16개 기업이 '종합물류기업'이라는 인증을 받기위해 건설교통부로부터 심사를 받고 있다. 올 상반기중에 우리나라를 대표하는 종합물류기업이 탄생할 것으로 기대된다. 이들 기업을 비롯하여, 물류기업들이 국내시장 규모만을 바라보고 경쟁하기 보다는 보다 넓은 해외진출을 꾀하여 글로벌 물류기업으로 다시 태어나야 할 것이다. '물류'라는 단어가 우리나라에 들어온지 불과 30년도 채 안되는 시점에서 동북아 물류중심을 외치는 우리의 물류산업은 비약적인 발전을 이뤘으며, 국내 시장이 아닌 중국을 비로한 해외 각국으로 진출하는 국제물류에 대한 관심이 높아지고 있다. 최근 21세기에는 북한, 아시아, 중국의 항만, 도로, 철도 등 하부구조를 크게 성장시켜, 권역 운송을 광역화하고 복합운송을 발전시켜야 한다는 의견과 더불어 물류시장의 개방을 통한 외국 운송업체들의 참여를 유도하여 국내 업체의 경쟁력을 키워야 한다는 업계의 의견이 조심스럽게 흘러나오고 있다. "만약 물류시장이 개방될 경우 우리나라 물류기업은 생존 대응능력은 있는가!"하는 의문은 종합물류기업들을 보면 답이 나올 것이다. 해외시장 개척을 적극적으로 펼치면서 외국 물류기업과 어깨를 나란히 하고자 하는 국내의 우수 물류기업들이 많다. 그 중 몇몇 기업들을 살펴보면 대한통운, 글로비스, 한솔CSN, 현대택배, 한진, 현대상선 등은 해외현지법인화를 통하여 글로벌 물류기업으로 도약을 꾀하고 있는 기업도 많다. 이번호에는 "국내외 물류기업의 해외진출 방향, 전략 및 사례"를 통하여 글로벌 물류기업으로 성장하고 있는 업체들의 해외진출현황을 간략히 살펴보고, 전략에 대해 물류전문가로부터 의견을 들어본다.

This study analyzed the changes in the operational productivity of fourteen Korean container lines from 2019 to 2021 using MP I(Malmquist Productivity Index). The results indicated that the operational productivity of the shipping companies has increased by 38.4% annually, representing the TCI (Technical Change Index) increasing by 58.3% and the TECI (Technical Efficiency Change Index) decreasing by 12.6%. The increase in the operational productivity of the container shipping lines was mainly attributed to the high rise in ocean freight rates rather than an increase in fleet size or ship technical efficiency. However, the deep-sea shipping lines (i.e. HMM and SM lines) experienced increases in both the TCI and TECI, which was not the case for other shipping lines(i.e. Intra-Asian short-sea shipping lines). The intra-Asian short-sea shipping lines enhance their productivity due to the TCI but failed to appreciate the cost savings of the increased fleet effects due to the low SECI(Scale Efficiency Change Index) values.

A rapid growth of interregional trade between China and Korea requires new development and expansion of ports. Currently, there is no rail-ferry system between China and Korea, however, a rapid growth of car-ferry industry shows possibilities. Several candidate cities and regions in East part of China and West part of Korea are selected. We identified times in clearance and station-to-station services as major benefits. We compared three transport modes including candidate cities and regions: container ships, car-ferry and rail-ferry. We used AHP (Analytic Hierarchy Process) as an evaluation method to select most competitive rail-ferry routes between two countries. We also used 7-point Likert scales to find out bottlenecks and factors to introduce rail-ferry services as other questionnaires. As a result, Rail Ferry System(RFS) is a little expensive due to wagon loading efficiency in cargo hold of the ship compared to Car Ferry System or Liner Shipping System. But RFS is recommendable in case of Block Train transport between Korea and EU area by may of TCR and TSR comparing Car Ferry System, because it can reduce total transport cost and connecting procedure at border lines of passing countries.

The purpose of this study is to investigate the empirical results of Analytic Hierarchy Process/Data Envelopment Analysis-Assurance Region(AHP/DEA-AR) by using multiple regression analysis during the period of 2009-2012 with 5 inputs (number of gantry cranes, number of berth, berth length, terminal yard, and mean depth) and 2 outputs (container TEU, and number of direct calling shipping companies). Assurance Region(AR) is the most important tool to measure the efficiency of seaports, because individual seaports are characterized in terms of inputs and outputs. Traditional AHP and multiple regression analysis techniques have been used for measuring the AR. However, few previous studies exist in the field of seaport efficiency measurement. The main empirical results of this study are as follows. First, the efficiency ranking comparison between the two models (AHP/DEA-AR and multiple regression) using the Wilcoxon signed-rank test and Mann-Whitney signed-rank sum test were matched with the average level of 84.5 % and 96.3% respectively. When data for four years are used, the ratios of the significant probability are decreased to 61.4% and 92.5%. The policy implication of this study is that the policy planners of Korean port should introduce AHP/DEA-AR and multiple regression analysis when they measure the seaport efficiency and consider the port investment for enhancing the efficiency of inputs and outputs. The next study will deal with the subjects introducing the Fuzzy method, non-radial DEA, and the mixed analysis between AHP/DEA-AR and multiple regression analysis.

Container Vessel is becoming larger and faster thanks to the rapid growth of global trade and development of technology. Therefore, 15,000TEU vessel is expected to be ordered in near future. Every nations in north-east Asia are facing strong competition to be logistics hub to get the initiatives of logistics in response to the rapid change of logistics environment. According to the globalization of economy and major ports in this region also are trying to catch big shipping line for their survival. Considering above circumstances of the advent of ultra-large container vessel and spoke-and-hub strategy, it is inevitably necessary to make a fast and accurate vessel job in the terminal in order to be a leading port To meet this objective, current vessel planning system has to be improved innovatively. Therefore, this thesis propose multi distributed vessel planning system which enables multi loading/discharging planning with several planner simultaneously for faster and more accurate than existing planning and enhances quality of planning through information sharing among planners. Also this thesis uses simulation through Arena to verify the efficiency of this multi-distributed vessel planning system.

With rapid growing of the Northeastern Asia, the interest for the connection of Infrastructure that was behind of interesting until now is getting larger. In a line of same connection, UN-ESCAP are forwarding transcontinental railway project, asian highway project et al.. And this study aimed at analysis on the effect that extended to a space by Korea-Japan undersea tunnel project. In aspect of a national land balanced-development to solve various problems such as overcrowding in capital region, unbalanced state by regions, weak exchange between South and North Korea, and weakness of national land basis to prepare for unification et al., this study consulted the economic potentiality model as a analysis method to examine an effect. In this analysis, I used 24 scenarios including all cases by combination of 3 scenarios for Korea-Japan undersea tunnel, 4 scenarios for transportation modes in the section of undersea tunnel, and 2 scenarios for adjacency infrastructure. Transportation modes in the section of undersea tunnel are railway, car-train, mixing way of railway and car-train, and mixing way of road and railway. Adjacency infrastructure applied railway and road. In all scenarios, Korea showed higher growth potentiality than Japan. Also, proposal plan C route relatively showed better in national land balanced-development than other proposal plans. The growth potentiality relatively appeared higher by buildup of a connection together with non-capital regions from the construction of Korea-Japan undersea tunnel. In aspect of Northeastern Asia, it resulted in a increasing of trade and chance of network formation in the region of Asia through infrastructure connection. But, in considering passenger and various factors that extended to the economic growth, this analysis have some limitation. Therefore, I hope that deep studies will continuously perform with various factors.
