Once it has been built, a container terminal is impossible to move to another location. It is hard to rectify wrong decisions in a container terminal. This highlights the importance of decision making for a container terminal. The port management about a container terminal has developed from a cargo interface location between sea and land transport, to the standardization of information and procedures due to globalization among global shipping and terminal operators. This research focuses on the current states of market and management for global container terminal operators by investigating up-to-date data for them. The current market states for global container terminal operators are analyzed by using by Herfindahl-Hirschman Index. The analyses of current management states for global container terminal operators are divided into profitability analysis, activity analysis, and bankruptcy risk analysis. Finally, global container terminal operators are clustered into three groups by the current management states.

CSD is IEEE Stan없rd 802.15.4b based Container Security Device which is proposed by the U.S Department of Home Security. It is mounted inside the container to sense opening of the container door. ConTracer is the CSD which is developed in this research whose major features are sensing door opening status as well as history inquiring on internal environment and shock to the container by mounting the temperature/humidity/shock sensors. Moreover, its RFID frequency bandwidth uses 2.4GHz 10 correspond actively to the radio regulations used by different countries. This. paper introduces the development trend of CSD, compares the ConTracer which is developed thru this research and other company's CSD, and introduces CSD System which is designed and established using ConTracer. Finally, the implemented CSD System is verified by applying the demonstration service to container distribution between Korea and Japan.

This study aims to suggest a containerization plan for non-standardized cargo; it also reveals the significance of containerization in facilitating freight inducement and cargo creation for increasing the competitiveness of the Gwangyang port container terminal and checking excessive competition among terminal operators. Therefore, this study suggested a containerization plan and its significance by dividing 14 items, ones with low containerization ratios or undergoing containerization, bulk, and liquid cargoes. In the case of general cargo, it will be necessary to raise the utilization rate by remodeling a general container or improving cargo loading techniques. In the case of bulk cargo, it will be necessary to exploit the benefits of containerization in preventing product deterioration due to rain, facilitating the sale of small orders, ensuring clean cargo handling, and reducing logistics cost, among others. In the case of liquid cargo, it will be necessary to order and sell liquid cargo in small quantities by using superior quality, safe, and durable Flexitank or Flexibag products, which offer transportation convenience and reduce time and costs.

Following the introduction of containerized sea transportation, the size of container ships has progressively increased. While the primary objective of this enlargement is to achieve economies of scale, it significantly affects the operational environment of ports where these ships dock, raising concerns about the validity of efficiency gains from ultra large container vessels from a port operational perspective. This study evaluates the efficiency of various ship sizes from January to December 2022, utilizing internal data from the container terminals A and B located in the Busan New Port. The analysis encompasses ships affiliated with The Alliance at Container Terminal A and those associated with 2M at Container Terminal B. Key input variables considered for the study include ship size (TEU), total berth time, and loading/unloading time, with cargo handling performance serving as the only output variable. The findings indicate that larger ship sizes exhibit higher efficiency compared to smaller container ships.

A ship runs with various modes of motion due to waves. Among the modes, roll mainly influences on the safety of cargos on the deck of container ship. In order to protect cargo shifting and turning, securing and lashing system are generally installed. In that case, it is necessary that the force and moment at the connection point of containers should be estimated. Therefore we derived mathematical equations to calculate the forces of securing points and lashing wires. Also we calculated those forces and moments about various lashing patterns.

Research has been actively conducted recently to secure the visibility of logistics by equipping cargo transportation containers with mobile communication devices. This paper describes the design and location selection for a mobile communication antenna to be mounted on a smart container to enable stable mobile communication. The mobile communication antenna proposed in this paper is a dual-band linear polarization antenna. Its operating frequency ranges are 698MHz - 960MHz and 1710MHz - 2690MHz, the VSWR is ≤3.1, and the gain is ≤3.5dBi. Once fabricated, the mobile communication antenna was installed on the container, and RSRP and RSRQ, the mobile communication radio quality indices, were measured to select the optimal location for the antenna.

In spite of a recent trend of container ships becoming larger in size, the current circumstance is that managing reefer containers marine transportation is being mostly dependent upon manpower. Particularly, in the case of bad weather or nighttime, reefer containers are not being monitored due to lack of safety device. For the purpose of reducing such risk, IMO is recommending a system using PLC but the system is not being used. In addition, they are still relying on manpower for control and reliability of freight in transit is decreasing due to lack of information during marine transportation for every subject related to freight as well as shipper. Accordingly, the purpose of this paper is to propose a real-time reefer container management system to effectively control all reefer containers widely being used across the world.

The role and ratio of national vessels in the global container shipping market have reduced significantly due to the bankruptcy of Hanjin Shipping in early 2017. All import-export companies, as well as container ports in Korea, are facing a crisis. The Trump's tariff and trade battles have had a negative impact on the increase in the North American cargo. However, Chinese and Japanese container shipping companies, which merged with domestic container shipping companies, and mega carriers such as Maersk and CMA CGM have benefited from the decline in shipping supplies due to the collapse of Hanjin Shipping, the world's 10th largest container carrier in Korea. The import/export freight trade in Korea is witnessing the increasing stronghold of foreign carriers. This scenario is expected to weaken Korea's negotiation powers with overseas shipping companies in domestic ports, such as Busan and Kwangyang, thereby making it more challenging to attract shipping carriers. This study compares the global container-shipping network in 2007 and 2017 by combining the network topology of the social network analysis and the economics of the liner shipping connectivity index (LSCI) and the container port connectivity index (CPCI) analysis. The findings of this study are that the role of the ports across the world can be identified, and CPCI has a high correlation with the centrality index and freight volume data. These findings can contribute toward the utilization of the meaning of the necessary centrality index without an additional centrality analysis. This study can be applied not only to the call strategy of container carriers but also to the alliance and development strategy of Korean ports.

자동화 컨테이너터미널은 ATC(Automated Transfer Crane)와 AGV(Automated Guided Vehicle)와 같은 자동화 운송 장비를 사용하는 컨테이너터미널이다. 이러한 자동화 컨테이너터미널의 핵심은 생산성을 향상시키기 위한 효율적인 장비 운영이 결정적인 역할을 한다. 본 논문에서는 AGV의 이동 위치 결정을 위한 RTK-GPS(Real Time Kinematic-Global Positioning System) 위치 정보 전송 및 운용 방법에 대해서 연구하였다. 이를 위해서 기존의 무선모뎀을 이용한 RTK-GPS 전송 방법을 무선 LAN(Local Area Network) 환경에서 RTK-GPS 위치 정보 전송 방법에 대해서 제안하고, AGV 이동 위치 결정 및 계산을 실험하였다.
