The purpose of this study was to analyze the effect of the shipping industry real economy index on the stock prices of domestic shipping companies. The parameters used in this analysis were the stock price of H Company in South Korea and shipping industry real economy indices including BDI, CCFI and HRCI. The period analysis was from 2012 to 2015. The weekly data for four years of the stock price index of shipping companies, BDI, CCFI, and HRCI were used. The effects of CCFI and HRCI on the stock price index of domestic shipping companies were analyzed using the VAR model, and the effects of BDI on the stock price index of domestic shipping companies were analyzed using the VECM model. The VAR model analysis results showed that CCFI and HRCI had negative effects on the stock price index, and the VECM model analysis results showed that BDI also had a negative effect on the stock price index.

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.

The lorry based transportation system in korea has many problems such as high domestic logistic cost, environment pollution and road damage etc. Hereupon, the necessity of improvement for national logistics system has been proposed continuously. Therefore we carried out this research through AHP(Analytic Hierarchy Process) to measure relative importance between effect factors and constraint factors and examined the possibility of Modal Shift from lorry transportation to coastal transportation. As the results of this research, the relative priority on modal shift policy enforcement (0.556) is higher than that of maintenance of the present transportation system(0.444).

블록체인의 잠재력이 높은 반면, 아직까지는 현장에서 완전히 검증되지 않은 기술이기 때문에 예상만큼 블록체인의 도입이 이루어 지지 않고 있다. 거래 정보에 대해 제 3의 신뢰기관에서 인증하는 기존의 방식과 달리 블록체인은 네트워크 참여자가 작업증명 등의 방식으로 인증하기 때문에 분산 원장 기술로도 불리는데, 이러한 특성으로 인해 네트워크의 규모가 확대될수록 데이터의 신뢰성 및 투명성이 강화되므로 소비자들의 참여를 촉진하는 것이 ····(중략)····.

Among domestic car carrier operating shipping companies, some shipping companies are operating a stowage planning system that is installed and executed on a computer, and most shipping companies are executing stowage plans with documents such as Excel. This is a study on how to utilize web service technology so that multiple users can use the planning system more efficiently in the cargo stowage planning process for car carriers.

The objective of this paper is to analyze the equipment combination of stevedoring system at port container terminal. In general, the productivity of container terminal is evaluated by productivity of container cranes at apron, but there are other equipment such as transport vehicles and yard cranes. Therefore, a method that can estimate the optimal equipment combination of stevedoring system in container terminal is required. We perform various simulation experiment and analyze equipment combination to improve the productivity. From the application of the case study, we demonstrated the savings effect using mean waiting time rates by the equipment combination.

Since 1996, the document exchange method by EDI has been introduced in port and logistics industries to enhance the declaration activities to the Pusan Port Authority and Customs. In spite of these efforts, users such as shipping companies, shipping agents, and freight forwarders have complained the inconvenience of using EDI systems. The major reasons can be summarized as too much transfer time, inconvenient EDI software, and problems on message receiving confirmation. To solve these problems, although we have developed an Internet based EDI system for Port-MIS users, we have failed its implementation practically for the short of Governments readiness, the complexity of systems and separation with in-house systems. So, the writers have changed the direction of research to applying the concept of SCM to logistics system by XML/EDI. In this Paper, the prototype systems to integrate processes of shipping company, Port Authority, Customs and stevedoring company will be suggested. The new method of EDI gives us advantages, which are the accuracy of cargo data and integration of processes among firms and keeping the service of cargo trace.

Gate operations are very important as they are the starting point for export containers and the end point for import containers as far as checking and control exercised by terminal operators are concerned. The objective of this paper is to propose the design of separated gate system in order to reduce the truck turnaround time and to distribute the truck traffic volume in port container terminal. Because of a lot of container load and unload within short term, many trucks have to pass the gate at a time. This study suggests the separated gate system as an efficient design for gate operation considering integration of two individual berth.

This paper aims to understand and analyze the mega-trends such as trends towards larger vessels due to an increasing trade volume, accordingly fewer port calls, strategic alliances and M&A Increasing degree of concentration through M&A activities in shipping industry results in a decreasing number of shipping finns with an increasing share in the world shipping capacity. But competition is strongly increasing on main trunk routes. Therefore, shipping concentration directly leads to further concentration of port traffic in fewer and larger ports with an increasing competition among neighboring ports.
