In the era of the 4th industrial revolution, automated technology innovation is emerging, and container terminals are being developed to introduce automation equipment and systems. With the advent of ultra-large vessels, terminals around the world are seeking to build port infrastructure by combining automated technology in order to attract more cargo and to enhance competitiveness to provide prompt service. To introduce automated technology that is emerging as a high-tech industry, this study proposes a structural equation model for the decision to introduce automated container terminal and conducts a questionnaire survey on workers engaged in terminal operators for empirical analysis. This paper presents the role and direction of guidelines for introduction of automated container terminal through decision model.

There have been cases where the number of port workers has temporarily decreased due to COVID-19. To prevent the spread of COVID-19, a number of workers were quarantined, resulting in bottlenecks and waiting throughout the port operation process, increasing the congestion of terminals. As a result, problems such as a decrease in terminal operation efficiency occurred. However, it is understood that congestion centered on unloading equipment inside the terminal is not clearly calculated. Terminal congestion is thought to be a key factor directly related to the operational efficiency of the terminal. The congestion calculation method generally used in various fields measures congestion based on image-based data. Due to the nature of the loading and unloading equipment that moves according to the quantitative loading plan, it is unreasonable to apply the existing congestion calculation method. Therefore, this study presented a method of calculating terminal congestion using equipment waiting time and turnaround time, and verified the statistical significance of the congestion calculated using data from Terminal A of Busan Port.

The purpose of this study is to propose the effective method to improve the competitive power in the Busan container terminal. To achieve this, we analyzed the present of the shift pattern in the container terminal, and identified the problems in the pattern. This study shows the issues of shift pattern for field employee in Busan container terminal and also improvement plan to solve them. We suggested two approaches as an effective approach; the flexible use of employees through overtime, use of workers pool among terminals, and outsourcing; the promotion of welfare by leisure, fitness, and community service.

International major container terminals are trying to expand automation facilities in order to dominate the competition and grow as central harbors. Recently, system design and development were put underway to fully integrate automation systems in container terminals. This is because it can focus on improving the efficiency of the yard operations in container terminals and facilitates integration with other container terminal operation processes. Automation in the container terminal business today is essential to better serve customers and improve profitability. Real-time position and status of container handling equipment (CHE) have been required for more efficient terminal operations and consequently higher productivity. This study examined the real-time location and status of the container terminal automation equipment using DGPS in container terminals, and reviewed the components and functions of the container terminal automation yard equipment systems that developed, applied, and operated the automation systems. In addition, this study compared the existing yard system and the automation yard system and presented application methods. Also, the results revealed that the productivity of the container terminal and the efficiency of the transportation equipment can be further increased when the optimal yard automation transportation equipment system is used to efficiently operate the transportation equipment, which is the core equipment of the container terminal.

In order to create value for maritime tourism industry, new port infrastructures have been planned, improvements in passenger terminal services have been designed, and new maritime transport technologies have been applied, so that ports improve their efficiency and the quality of their service more than their national and international competitors. Thus, the purpose of this study is to verify the dimensions of the service quality of ocean passenger terminal. Based on a survey of 260 customers in port of Busan and Inchon, terminal service quality's five main dimensions have been checked regarding their fit with the use of Confirmatory Factor Analysis. Empirical results support that this is a valid instrument for measuring service quality of a ocean passenger terminal. The interactive sequence of computing Cronbach's alpha, corrected item-to-total correlation, and factor analysis was repeated a few times and resulted in a final set of 19 items representing five distinct dimensions-tangibles, responsiveness, knowledge, reliability, and accessibility. This finding provides the more appropriate instrument to evaluate the customers perception as well as to measure the service quality of ocean passenger terminal.

터미널 호스트(Terminal Host)란 사용자가 네트워크를 통하지 않고 직접 사용하고 있는 호스트를 말한다. 사용자가 네트워크를 통해 특정 호스트에 로그인할 경우, 특정 호스트를 지키던 방화벽을 해당 사용자의 터미널 호스트를 인증하는 것이 아니라 해당 사용자가 네트워크을 통해 직접 특정 호스트에 연결시킨 호스트만을 인증하게 된다. 만약 사용자의 터미널 호스트가 보안상 위험에 노출되어 있다면 특정 호스트는 방화벽으로 보호를 하고 있음에도 불구하고 역시 똑같은 위험에 노출되게 되어 보안상의 커다란 위험이 된다. 본 논문에서는 이러한 위협을 없애기 위해 통합 방화벽에 적용가능한 효율적인 터미널 호스트 추적 기능을 제안하고, 터미널 호스트 추적 기능을 갖춘 FreeBSD기반의 통합 방화벽의 설계 및 구현 내용을 기술한다.

In these days, a scale of system is more and more complex and large. The centralized system has the operation management method to be limited in the large scale system. In this paper, we proposed ACOS(Autonomous decentralized Container terminal Operating System). It is applied to container terminal using by autonomous decentralized system which can solve the problem of the centralized operation system. Also, we can defined a function of the ACOS's sub-system and showed a flowchart on operation method for the ACOS.

운송 서비스산업에 대한 지속적인 규제완화는 운송 기업의 진입 및 퇴출을 자유롭게 하였고, 외국 기업의 국내에서의 영업 활동이 가능하게 했을 뿐 아니라, 업종간 분류를 무의미하게 하여 운송기업은 전방위 경쟁을 피할 수 없게 되었다. 이러한 경쟁 환경하에서 운송 기업의 효율적인 운영은 국가 물류비 절감 측면에서, 그리고 해당 기업의 사활 측면에서 매우 중요한 의미를 갖는다. 소화물 일관 수송은 택배 또는 특송이라 불리우는 운송 서비스업의 일종으로, 화주 한명의 화물량이 차량 한 대 분량에 못 미치고, 고객이 원하는 출발지에서 목적지까지 운반해주는 특성을 가지고 있다. 소화물 일괄 수송은 지역을 순화하면서 화물을 접수하여 인근 터미널까지 운반하는 수집과정, 터미널과 터미널을 연결하는간선수송 과정, 터미널에서 최종 목적지까지 운반하는 배달과정을 거쳐 이루어진다. 본 연구를 통하여 터미널과 터미널을 연결하는 간선 수송과정에서 발생하는 비용을 줄이는 화물운송경로를 찾아주는 네트웍 최적화 모형이 개발되었으며, 이를 실제 업무에 적용하여 화물운송 경로를 조정함으로써 적재율 20%이상 개선, 운송비용 10%이상 절감이 가능함을 확인하였다.

본 연구에서는 컨테이너 터미널의 자동화 설비 중 안벽용 크레인(Quay Crane: QC)과 장치장용 크레인(Automated Transfer Crance: ATC)간의 컨테이너 이송을 담당하는 AGV(Automated Guided Vehicle)의 운영에 관한 시뮬레이션을 수행할 수 있는 전용의 시 뮬레이터를 개발하는데 목적은 두고 수행하였다. 자동화 컨테이너 터미널의 처리 능력은 선석의 QC 능력에 의해서 결정되지만, QC의 능력을 최적화하기 위해서는 컨테이너 터미널 내에서의 AGV의 운영 효율이 결정적인 역할을 한다. 또한 AGV의 운영 효율에는 장치장의 ATC 작업시간이 영향을 준다. 연구결과, AGV의 운영 효율 평가를 위한 시뮬레이터를 개발하였으며, 이를 이용하여 QC의 작업시간과 ATC의 작업시간에 따른 AGV의 적정대수를 산출하였다. 본 시뮬레이터는 실제 컨테이너 터미널의 운영 상대와 유사한 시뮬레이션을 수행할 수 있고, 컨데이니 터미널의 운영 능력을 산출하는데 적합하도록 개발되었다.
