This paper aims to propose optimal method to assess and cumulate the daily profit for liner shipping to support the shipping lines in making optimal decision with the highest average daily profit. This paper not only explains the actual calculated results align with decision-makers' behavior from concepts indicated in cumulative prospect theory but also contributes to an easy-to-apply method for liner shipping network predictability in and provides optimal decision-making is helpful for shipping managers for the best effective selection of the most appropriate alternative under uncertainties.

Information which port provide to users including shipping companies is essential information for their business performance. Thus, information service of several services which port provide to shipping company is also very important port-logistics service. However, despite of this importance, there have been little research related to port-logistics information service. The aim of this study is to analyze the satisfaction of information service for port logistics. To achieve this objective, evaluation criteria consisting of 16 items based on the previous research was established. And satisfaction index that can effectively show the current level of information service for port logistics was developed. The results of analysis showed that satisfaction index of information service provided by Busan port was 61.90. And from the data analysis, it was revealed that current level of information service in whole area was less than 63 points. It was implied that improvement for overall port-logistics information service was needed. Finally, from the follow-up research, it was found that information service provided by Busan port have weakness in the aspects of unification of information and celerity of information.

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)····.

Determination the optimal containership size is the most important factor for competitiveness if shipping companies. Accordingly, the objective if this research is determining the optimal containership size by service routes. Total shipping cost is calculated at the ground if capital cost, vessel operation costs, voyage costs, port charge and miscellaneous cost for 'Europe-Far East', 'Far East-North America' and 'Europe-Far East-North America' Services. Finally, the optimal containership size was utilized through total shipping cost, slot quantity if containership and average throughput by containership.

As port functions change to act as an economic catalyst and take on a central position in industries engaged in international trade, port hinterland has become a significant component in international shipping. The success of port hinterland as a strategic base of logistic activities critically depends on location selection factor for international distribution center that links elements of global supply chain management. By examining multi-measurement items empirically, this paper analyzed location selection factor for international logistics distribution center in port hinterland, and evaluated Busan new port hinterland from the user's perspective. Employing exploratory factor analysis, the results revealed that the model structured around five factors incorporating geo-location and accessibility, availability, political supports, cost factors, and quality of business environment is valid and reliable in the context of the location selection factors for logistics distribution center in the context of port hinterland operations. The evaluation of Busan new port hinterland provides useful insights for strategic improvement to accommodate the users' expectation. Further, the model offers both a descriptive and diagnostic strategic management tool for port hinterland development and operations, to guide future improvement.

The purpose of this study is to examine the growth status and future prospects of the shipping industry over the past decade through a review of the statistical database and related literature. We classify the shipping industry and survey a number of companies, number of employees, sales trends and shipping logistics market outlook, port cargo volume, and container throughput trends with regard to the sea cargo shipping business, freezing cold warehousing business, harbor cargo unloading business, and international freight forwarding business. We will also look at the overall trends, scale, cargo volume, and harbor automation status of the global shipping market.

To study the business performance, this research reviewed the revenue of 2012 for shipping and logistics companies in Korea, then selected 10 shipping companies and 10 logistics companies according to annual sales amount. These 20 companies are divided into four groups considering their business structure and their financial performance are organized from 2005 to 2012. Then CCR, BCC model has been applied to static efficiency and dynamic changes in productivity for analysis. As an overall result, logistics companies are proven to be better than shipping company in efficiency, change of productivity, growth and profitability. Among the logistics companies, the performance of second party logistics companies are relatively better in those factor above than the third party logistics companies.

In recent times, an obvious strategy in liner shipping markets that has come to the fore is slow steaming. Nowadays, most liner shipping companies have decelerated the voyage speed to 15-18 knots on major routes, and some leading liner shipping companies have a plan to reduce it to below 15 knots. Slow steaming is helpful in reducing the operating cost and the amount of greenhouse-gas emissions on a single vessel with lower fuel consumption. However, it also creates various negative effects such as the opportunity cost, additional fixed costs and an in-transit inventory cost on a loop. Hence, the net operating cost on a loop is changing dynamically due to the changes of voyage speed based on various slow steaming effects. The aim of this study is to analyze the slow steaming effects in the liner shipping, and to find the best voyage speed that minimizes the operating cost on a loop. Moreover, this study suggests the recommendable strategy for liner shipping companies. To achieve the aim of this study, a simulation model has been designed using System Dynamics.

This paper analyzed tendency of research of articles published in the Journal of Shipping and Logistics from Vol. 51 to Volume 60. The results of the analysis are as the following: First, the subjects mainly researched in shipping and in logistics are port economics/management and logistics management/operation in the proportion of 35.0% and 13.7%, respectively. Second, university professors carry out research more actively than other research groups. Third, quantitative analyses are more often used than qualitative analyses for research method. Finally, Korean literatures and English literatures are used at the same rate for reference. In conclusion, for the development of the Journal of Shipping and Logistics, the subjects should be diversified, systematic collaboration between educational and industrial circles is required. and cooperation with foreign academies should be continued.

Coastal cargo shipping is regarded as environmentally friendly and less costly compared to other transport modes: therefore, many developed countries endeavor to activate coastal cargo shipping. In Korea, a couple of policies are suggested for coastal cargo shipping; however, shippers' aspects seem to be neglected or not analyzed. In this regard, this study aims to identify barriers in the coastal cargo shipping, in respect to shippers' aspects. To find out the reasons shippers hesitate to use coastal cargo shipping, we made a questionnaire and surveyed. We found out some meaningful points in this study as the followings. First, the proportion of using the coastal cargo shipping is very low. Second, the shippers give weights on time and costs factor, and their preference for punctuality and stability of the transportation services is extremely high. Third, the shippers believe that improvement of the services of the coastal cargo shipping is very important in national logistics system although most do not use currently. They also believe that the success of coastal cargo shipping lies in whether it can transport the huge amount of cargos with lowest costs. Finally, the most important factor, when they choose the transport mode, is the punctuality and stability of the transportation services.
