Since service competition among global supply chains became intensified, market-oriented system, instead of the existing cost-based system, for port service pricing has been strongly recommended in order to enhance their long-term viability and competitiveness. The Owen value of cooperative game frameworks allows us to apply a market-oriented pricing theory for the port pricing in the case of Gwangyang port to verify its usefulness. The analytical results of this paper suggested some solutions in the problem of berth-based cost allocation by a characteristic function and also showed the proper relative weights of factors to derive the quay use index by Budescu(1993). We also suggested a favorable port pricing system to major shipping firms as well as a discount port pricing system for their strategic alliance. To put it differently, the results of this study enable the port managers to make out some strategic port pricing system like the reasonable discount in port charge for the larger ship owners using the ports frequently.

The purpose of this study is to clarify a safety efficiency of ports in South Korea considering port casualties. The paper conducted a vector auto regression to analyze a cause-and-effect relationship between latent factors and port casualties. Subsequently, the paper evaluated safety efficiency for the ports using an undesirable outputs model. The results implied that the number of workers in the shipping union had a statistical effect on the port casualties. In contrast, the number of workers in the operators and working hours are unrelated to the port casualties. In addition, it was found that Yeosu Gwangyang Port is the most safety efficiency port in South Korea. Based on these results, this paper may provide various policy implications for port operators, developers, and managers.

In this paper, the method of detecting sea fog through CCTV image is proposed based on convolutional neural networks. The study data randomly extracted 1,0004 images, sea-fog and not sea-fog, from a total of 11 ports or beaches (Busan Port, Busan New Port, Pyeongtaek Port, Incheon Port, Gunsan Port, Daesan Port, Mokpo Port, Yeosu Gwangyang Port, Ulsan Port, Pohang Port, and Haeundae Beach) based on 1km of visibility. 80% of the total 1,0004 datasets were extracted and used for learning the convolutional neural network model. The model has 16 convolutional layers and 3 fully connected layers, and a convolutional neural network that performs Softmax classification in the last fully connected layer is used. Model accuracy evaluation was performed using the remaining 20%, and the accuracy evaluation result showed a classification accuracy of about 96%.

This study proposes a deep reinforcement learning-based algorithm to automatically generate a ship's passage plan. First, Busan Port and Gwangyang Port were selected as target areas, and a container ship with a draft of 16m was designated as the target vessel. The experimental results showed that the ship's passage plan generated using deep reinforcement learning was more efficient than the Q-learning-based algorithm used in previous research. This algorithm presents a method to generate a ship's passage plan automatically and can contribute to improving maritime safety and efficiency.

Due to the change of global production network, the establishment of new strategy in Korea ports is required Especially, the trade pattern has been mainly concentrated in Northeast Asia region according to economic growth of the Asia including China, Japan, and Korea. Hence, Korea major ports with the competition of price and service has to meet the need of Northeast port alliance and has to compete against other countries in variable trade environment. Therefore, the objective of this study is to propose a port alliance strategy in order to promote the transshipment of Korea major ports such as Pusan port and Gwangyang port. In order to establish the logistics business model in the ports, we provided the direction of the Northeast port alliance and candidate ports in China and Japan.

모든 조직들은 자신들의 업무관행이나 운영전략 등의 개선을 통한 조직효율성의 재고를 위해 다양한 노력들을 기울이고 있다. 해운항만산업의 첨두에 있는 컨테이너 터미널의 경우도 예외가 아니며, 이러한 목적을 위해 벤치마킹기법이 사용될 수 있다. 벤치마킹 기법은 자신들 내면을 파악한 후 동종업계의 최고업무처리관행(best practices)조직을 참조하여 자신들의 업무 효율성을 향상시키는 방법이다. 국내 컨테이너항만의 후발주자이면서, 물동량의 증가율도 높지 않아 지역민이나 전 국민의 우려대상이 되고 있는 광양항도 다양한 방법을 사용한 발전을 모색해야만 하며, 이러한 방법적용을 위해 대표적으로 사용할 수 있는 것이 자료포괄분석법(data envelopment analysis, DEA)이다. 본 연구는 부산항과 광양항에 있는 중소형 9개 터미널의 1999${\sim}$2004년간의 4년자료를 통해 광양항 컨테이너터미널의 문제점과 그 원인을 살펴보고, 벤치마킹기법을 이용해 이를 개선하기 위한 행동방안을 간략히 제시해본다. 추후에는 최근의 다양한 변수와 국내외의 다양한 대상을 통한 더욱 엄밀한 분석을 수행해야 할 것이다.

The traditional measures of a container port (or terminal) efficiency such as crane productivity, cargo throughput, etc. were generally presenting the partial efficiency since they evaluated only each individual factor and based on cross-sectional data. To overcome this problem, and in an effort to help port authorities develop a winning strategy in the increasingly competitive container transportation market, this Paper develops a meaningful set of benchmarks that will set the standard for best practices. In particular, this paper proposed a combined method to merge the DEA and simulation technique over time. To illustrate the usefulness of the proposed combined DEA/simulation model, this paper used the panel data of the four Gwangyang container terminals and seven Busan container terminals in Korea over the four-year period of 1999 through 2002.

China has increased 10 percent every year since 1978. In particular, development and growth of Chinese ports make a remarkable in that the marine and coastal transportation handles the 90 percent of export-import cargo. This growth is beginning to threaten Korea's ports which are striving to become the hub of Northeast Asia logistics. Furthermore, the hub strategy of Northeast Asia is closely related to transshipment cargo invitation. The results of documents research indicate Busan and Gwangyang ports play an important role as an intermediate stopover between China and America. The ways to achieve transshipment cargo invitation are the construction of transshipment system based on the supply chain between korea and china, the maximization of trading volumes creation, equipment of ports infrastructure, and the constructions of the rail, road, coastal transportation infrastructures.

One of the world's major resources is crude oil, the most fundamental part of the industry. There is no place that does not use crude oil. Petroleum refining products and chemical production industrial products are produced through nearby petrochemical complexes and ports after importing crude oil. There would be a possible relationship among the petrochemical complexes and nearby regional ports working with liquid cargoes. To confirm these relations, Ulsan Port, Daesan Port, and Yeosu Gwangyang Port were selected for this study. A Vector Auto Regressive model using time series data was applied. A Unit Root Test was performed. The relationship was confirmed through the Granger and Toda Yamamoto Causality Test.

Recently the port logistics service has been recognized as a important function of the international logistics, therefore, a lot of papers have been issued concerning the measurement of the service quality of that. But in spite of variety of papers, we can not find out the papers concerning the model of the synthetic customer satisfaction. And also the most of papers concerning the customer satisfaction of service quality have been focused not by cognitive evaluation of the customer, but by affective response. In this thesis, the authors are postulating the model and hypothesis to achieve the research by using the Gr$\"{o}$nroos's model. In order to research the relationship between the port logistics service quality and the customers satisfaction, we are selecting the shipping companies located in Busan and Kwangyang as purchaser and the loading and unloading companies as supplier, and the questionnaires was performed to them. In the result of the empirical study, the technical quality of the port logistics service are affecting directly on the customer satisfaction, but the functional quality are affecting not directly on the customer satisfaction. And also the customer response(affective response) has been proved that it has been exercised as a intermediate role between the port logistics service quality and the customer satisfaction. Therefore it is proved that the affective response of the customer has been exercised a crucial role in the course of supplying the port logistics service.
