This paper investigate the problems of standard container port handling capacity in establishing national port development plan in Korea. Considering container port developing, it's not easy to adopt container port service quality parameters such as lay time constraint of very large container ships by using the standard guideline of container port handling capacity. A simple methodology that connects vessel waiting to service time(w/s) and berth occupancy to costs has been used to evaluate the performance of a container terminal. But the total handling capacity have to be calculated by the performance of the handling system and number of equipments and layout of terminal by using computer simulation that represents of reality events needs to be performed by probabilistic techniques. A simulation model of estimation of container terminal capacity is introduced in order to establish a hub terminal for very large container ships that focus the port's quality of service and also suggest as tool for policy maker to justify a required port investment.

Recently, various technologies such as logistics automation and port operations automation with ICT technology are being developed to build smart ports. However, there is a lack of technology development for port safety and safety accident prevention. This paper proposes an AI-based shipping container loading safety management system for the prevention of safety accidents at container loading fields in ports. The system consists of an AI-based shipping container safety accident risk classification and storage function and a real-time safety accident monitoring function. The system monitors the accident risk at the site in real-time and can prevent container collapse accidents. The proposed system is developed as a prototype, and the system is ecaluated by direct application in a port.

The purpose of this study is to analyze traffic volume between the Korean container ports located at the west coast and northern Chinese ports and then the distribution trend of container between Korea and China. The findings of the study are as follows. First, Container traffic between western Korean ports and northern Chinese ports has been increasing due to an increasing trade volume between both countries and geographical accessibility. Second, Seoul and neighboring area tend to use the trade route between the western ports and northern Chinese because of lower logistics costs and time-saved advantage compared to another ports. Third, the growth of the western ports did depend mainly on the northern China oriented growth. Such a fact could leads to the overlapping investment in port development in Korea and another intense competition among national ports to attract cargoes and liners. Therefore, port development policy considering the characteristics and function of national ports have to be established. and also alternatives and strategies for improving the competitive edge of small and medium sized shipping lines against the opening of shipping market have to be worked out.

With its foreign trade rapidly expanding and with economic growth continuing at a substantial rate, China has become the largest container traffic generating country in the world. And with trend of container ships becoming larger and faster, the environment surrounding ports in North-East Asia are rapidly changing. The Yangsan, offshore port for Shanghai, being developed on the islands of Da Yangsan and Xiao Yangsan, some 30km offshore, and connected to the mainland by the six-lane highway Donghai bridge, opened phase one in late 2005 and phase two in 2006 respectively and will have 29 berths by 2012 and be able to handle 15 million TEU. The Port of Shanghai which passed Busan in terms of container volume further consolidated its position as the world's No. 3 port with an annual volume of 21.7 million TEU in 2006 and is likely to have emerged as the biggest container port in the world. The Port of Busan, the world's fifth largest container port, wants to survive as regional hub port. In this circumstance, the strategies of the Port of Busan should be established.

지난 15년간 한국경제는 두 번의 금융위기인 1997년의 아시아 금융위기와 2008년의 글로벌 금융위기로 인해 엄청난 경제손실을 입었다. 이와 같이 우리 경제의 고유한 문제이기 보다는 외부에서 발생한 일련의 사건들은 GDP와 같은 국내 거시경제지표들뿐만 아니라 국내 항만들의 컨테이너처리물동량에도 많은 영향을 주었다. 본 연구에서 두 번의 금융위기를 독립적이며 상이한 형태의 외부의 영향으로 가정한 뒤, 국내 항만들의 컨테이너처리물동량에 어떤 영향을 주었는지에 대한 개입분석을 수행한다. 그래서 각기 다른 충격들에 대한 컨테이너처리량을 변화와 함께 그 충격들 간의 특성규명을 통해 우리나라 항만산업에 다양한 시사점을 제공하고자 한다.

This paper analyses the relative efficiency of 13 container terminals based on the data for the period 2003-8 to offer a fresh perspective. There has been abundant empirical research undertaken on the technical efficiency of Busan and Gwangyang port. Most studies have focused on the use of parametric and non-parametric techniques to analyse overall technical efficiency. Here, the framework assumes that terminals use two input to produce one output; the former includes container yard and container crane and the latter container volume. Jarque-Bera indicates that three variables are not normally distributed and the positive skewness shows that all the variables have long right tails. This means there are many small-scaled container terminals. This paper also employs heteroscedastic Tobit model to show the effect of the explanatory variables on the container terminal efficiencies. The Tobit model shows that both container yard and container cranes have positive effect on the container terminal efficiency, but container yard has a higher impact on the efficiency than the container crane.

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.
