In this paper, the reduction of green house effect gas CO₂ emission and NOx gas emission by using the RORO ship coastal transport of import-export container cargo was investigated. At first, the domestic CO₂ gas emission and the transportation of import-export container cargo were Investigated. Next, the characteristic of a RORO ship and CO₂ emission standard and NOx emission standard were investigated. And also, the reduction of CO₂ emission and NOx emission by the shift of coastal transport from land transport for the transportation of import-export container cargo between Kyongin area and Pusan Port were calculated. Finally, the change of CO2 and NOx gas emission due to the change of the share of coastal transportation and the load efficiency of RORO ship are investigated. The research results show that the shift of RORO ship coastal transport from land transport was very effective to reduce the CO₂ emission but it was no good to reduce the NOx emission.

The purpose of this study is to analyze the relationship between export weight, import weight, export amount, import amount, and trade balance of ICT industry. The data used were gathered from the Korea Customs Service trade statistics. The analysis period used annual data for 19 years from 2000 to 2018. The change rate analysis was shown in order of trade balance, export amount, import amount, import weight and export weight. The increase rate analysis showed that the trade balance was the highest at 919%.. In the correlation analysis, the trade balance and export amount were 0.95, showing the highest correlation coefficient. As a result of the regression analysis, the export amount for the trade balance, the dependent variable, was Coefficient 2.37, which was positive(+). Each variable is changing independently of one another. Since 2000, the trade balance of the Korean ICT industry has led 84% of Korea's total trade balance. In the future, Korea's ICT industry should be further developed for Korea's economic development, and exports should be further increased to increase the trade balance. In the next paper, we will try to find a field that can be specifically developed by subdividing the ICT industry.

The port industry is an important national industry which significantly affects Korea's imports and exports which are centered on economic structure. For instance, the Port of Busan, which handles 75% of domestic container freight volume, is expected to become increasingly critical for container liner routes. For this reason, there have been continued efforts to expand freight service to attract international freight volume. This study analyzes the structural characteristics of the port network connected to the Port of Busan by analyzing the pattern of the container liner route from 2012 to 2016 by using social network analysis. According to the Port of Busan's liner route network, the port with the highest degree of centrality, closeness centrality, and betweenness centrality was found to be the Port of Singapore. The comparison of Busan's annual container handling rank by countries and the port center network analysis of Port of Busan rank was found to be different. As a result, it was established that China's East Port, which occupies a high percentage of the volume of cargo handled by Port of Busan, is not a hub port of Busan when viewed on the Busan's container terminal liner network. In addition, even if the number of Port of Busan container liner service increases, it is estimated that the vessels to be added to the fleet will be limited to small to medium sized, or that Busan port has characteristic of a feeder port for the Port of Singapore, according to the network.

Pyeongtaek Port is becoming a specialized for importing or exporting cars. In 2010, Pyeongtaek Port became the major port, out of the 31 ports in Korea, for import and export of cars. Usage of this port was especially high for imported cars. In 2011, more than 1 million cars are expected to be imported or exported via Pyeongtaek Port. This research analyses the factors for selecting Pyeongtaek Port for imported cars and recommendations required to improve Pyeongtaek Port. To do this, questionnaires were given to 14 imported car companies that currently, July 2011, use Pyeongtaek Port and used AHP criteria to asses the importances of each factors. According to this research, the most important determinant for the use of Pyeongtaek Port is 'Port Location' followed by 'Port Cost', 'Port Facility', 'Port Service', 'Port Marketing' and 'Port Cargo Volume', in the order of importance. Also, imported car companies say that the factor in need for the most urgent improvement is 'Port Facilities' in Pyeongtaek Port.

태평양 도서국은 간선항로와 먼 거리, 적은 물동량, 수출입 불균형 등으로 해상운임이 높게 형성되어 있으며, 기후변화에 취약하여 항만운영에 제약이 많은 등 해상운송이 상당히 열악한 실정이다. 또한 해상운송 의존도가 상당히 높은 반면, 정기선 연계정도는 상당히 낮아 해운물류 경쟁력을 향상 필요성이 증대되고 있다. 따라서 본 연구에서는 사회연결망분석(SNA)를 통해 14개 태평양 도서국의 국가 간 해상교역 구조를 파악하고 이를 통해 해상운송망 강화를 위한 방안을 제시하였다. 분석 결과, 대상국가 간 교역구조는 점차 복잡해지고 있으며, 점차 피지, 사모아, 파푸아뉴기니 등을 중심으로 Hub-spoke 체제의 해상운송 네트워크가 형성되고 있다. 역내 해상운송망 강화를 위해서는 분석결과에서 도출된 역내 주요 항만을 환적항으로 개발하여 해상운송 연계성을 강화하고, 카보타지 허용을 통한 정기선 입항빈도 증대, 인프라 개선을 통한 항만 운영탄력성 강화 등이 필요하다.

This study aims to investigate the relationship between cargo volume and logistics performance index published by World Bank which indicate countries' logistics performance. In this study, the results were derived through panel regression analysis consisting of variables such as gross domestic product, geographical distance, population, and LPI using container export/import volume and bulk export/import volume as dependent variables. As a result of the empirical analysis, it was found that Korea's container volume was affected by the overall level of logistics, in particular, was deeply related to the logistics infrastructure, while bulk volume was not related to the logistics level or was less influential.

Since Korea has excellent port infrastructure and competitive petrochemical complexes, there is plenty of potential for creating an oil hub in Northeast Asia. In particular, Ship-to-Ship (STS), which creates high added values, contributes greatly to the national economy. In this study, the liquid cargo volumes of chemical industrial products, refined petroleum products, and crude oil were analyzed at the national and regional (Busan, Ulsan, and Yeosu/Gwangyang) levels. Additionally, a Granger causality analysis was performed between imports, exports, and transshipments, in pairs. ADF, PP, and KPSS were analyzed for the unit root test. In addition, the VAR model and expanded VAR model suggested by Toda and Yamamoto were used for further analyses. Findings revealed a difference in Granger causality depending on the region or cargo type. These findings suggest that policies and incentive schemes for ports need to be differentiated according to the region and cargo types. In addition, the different patterns in the relationship between transshipments and import-export petrochemical cargoes should be considered.

Korean shipping industry is ranked the fifth largest in the world in terms of deadweight tonnage after Greece, Japan, Germany and China with 55 million DWT as of year 2011, and its size of foreign exchange earning marked 30 billion US dollars. In respect of volume of seaborne trade, it has handled 99% of import and export cargoes. Korean shipping fleets have increased from 420 to 979 ships between year 2003 to year 2011. By reviewing through the relating literatures, it has been found that Shipping Funds under Ship Investment Company Act, and Tonnnage Tax System, worked as positive influences to increase the Korean shipping fleets. However, there is scant of research to examine the following two points: 1) weighing the decision making factors of ship investments for Korean shipping companies, and 2) weighing the influential factors of government shipping policies. In this respect, the aim of this study is to evaluate 8 decision making factors of ship investments for Korean shipping companies, and 8 influential factors of government shipping policies. For weighing the factors, the fuzzy methodology was adopted. As the results, for the side of decision making factors of ship investments, 'shipping market conditions and future prospects', 'ship's price and future prospects, and 'securing cargoes and future prospects' are ranked as top 3 factors. For government shipping policies side, 'shipping finance provided by lease companies', 'establishment of Korea Shipping Guarantee Fund', and 'establishment of Korea Shipping Finance Corporation' are verified as the important factors.

All the major ports around the world as well as those in Korea have been exploring their own strategies to survive rapidly changing marine transport environment worldwide. In particular, Busan New Port under development still fails to meet expected logistical traffic, although it operates 6 berths. That is why it is necessary to point out current challenges in logistical strategy of Busan New Port for fully dealing with logistical traffic. Therefore, this study can propose the following ways to facilitate logistical traffic of Busan New Port. First, it is necessary to apply equal tariff to incentives given to shipping agent under the associations between existing harbors and Busan New Port. Second, it is required to increase governmental subsidy for truck freight transport. Third, it is demanded to seek possible ways to transport export and import freight and thereby create independent logistical traffic. Fourth, it is necessary to contact shipping agents residing in new ports and establish a logistical program for shipping freights via Europe, Middle East and Russia as well as those by way of North America, Japan, Korea and China, ultimately making sustainable marketing strategy to create a series of continuous transshipment freight, not temporary one. Finally, it is advisable to operate networked logistical programs with small- or medium-sized overseas shipping agents in business association with large-scale overseas shipping agents.
