Every port is competing for attracting loyal customers from other ports to achieve more profits stably. This paper proposes a data-mining scheme to facilitate this process. For resolving the problem, the OD (Origination-Destination) data are gathered from the AIS (Automatic Identification System) data. The OD data are clustered according to the arrival dates and ports. The FP-growth algorithm is applied to mine the frequent patterns of ships arriving at ports. Maintaining a loyal customer list for port updates and accuracy is critical in establishing its usefulness. These lists are critical as they can be used to provide suggestions for new products and services to loyal customers. Finally, based on the frequent patterns of the ships and the mode of arrival times, a formula proposed in this paper to derive shipping companies' loyalty to ports was applied. The case of Kaohsiung port was shown as an example of our algorithm, and the OD data of ships in 2017-2018 were processed. Using the results of our algorithm, other rival ports, such as Shanghai or Busan, may attract customers no longer loyal to Kaohsiung ports in the last two years and attract them as new loyal customers.

This study is aimed to contribute in establishing new port policy by research and analysis in design of global port logistics network in the East Asia region. In order to build such port logistics network, 21 ports located in East Asia among the world's 50th largest ports were selected in this study. Furthermore, the amount of container cargo and the ports of call were analyzed to categorize the subject ports in East Asia. Finally, this study tries to find economic network between the base port in East Asia, EU or North America and feeder ports in terms of logistics cost. As a result, Singapore, Hong Kong, Shanghai, and Busan ports were found as the representative ports in the East Asia that may connect North America and Europe with the minimum logistics expenses. Therefore, to maintain the stable cargo volume in ports, Korea should promote not only the overseas terminal operation which links to the Singapore, Hong Kong, and Shanghai ports, but also establish the global port logistic network connecting the Busan port.

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%.

The purpose of this study is for providing a strategic plan of waterfront belt development at the coastal area of Busan city that might enhance the possibility on healthy use of spare time of the residents and demand of tourism, together with raising the potential and the value added effect of coastal space. This study is one of a series of studies for developing waterfront belt at Busan coastal area. In this study we suggest the new concepts of waterfront belt, waterfront cluster and waterfront greenway. And then we present a model of making waterfront belt through waterfront cluster, which is an aggregate of individual waterfront spaces, using waterfront greenway. After that we apply this model to Haeundae coastal area and test the applicability of the model.

This paper focuses on the integration aspect of operators to determine an improvement strategy for the operating system to enhance competitiveness of Busan Port. This Study proposes the following alternatives: valuation standards for the integration of operators, the road map for the integration period, the scope and role setting of integrated operators' participation of Busan Port Authority(BPA), and the separation and linkage North Port and the New Port operators. First, the valuation standards for operator integration should be based on international standards. Additionally quantitative factors such as financial situation, business performance and participating companies' profitability, and the qualitative factors such as management ability, technology, and labor relations should be considered. Second, the timing of North Port's operator integration should be prioritized in the short term in conjunction with the commencement of its phase 2-4, 2-5, and 2-6. The integration of New Port operators should provide a road map for a relatively long-term perspective. Third, the participation of BPA' integrated operators should be considered in terms of publicity as a policy coordinator between terminals and by pursuing the profitability of entering into overseas business by fostering Korean global terminal operators. The scope and role of participation ensures that the experience and technology of the terminal operation business is maximized. Fourth, because physically intergrating the North Port' operator into a single corporate form is difficult, initially establishing a special purpose company to maximize the effect of the integrated operation is necessary. Then, the operators decided to convert to a holding company given the termination of the lease term contract with the State or BPA, and ultimately proposed a merger into a single corporation.

In this research we present a new model, PLCM(Cort-Logistics Chain Management), which can cooperate each other in the port-logistic industry that occupy a heavy rain in the Northeast Asian economy. PLCM(Port-Logistics Chain Management) synthetically manages the logistic chain and information laying stress on the port. Unlike SCM, which hat a vertical relationship between the main groups to cooperate each other, PLCM has a horizontal relationchip between the ports to achieve common purpose and to improve their whole competitive power. In this research we present a concept of PLCM and a specific plan to develop a system for PLCM targetting Pusan, Shanghai, and Tokyo Port which occupy a heavy rain in the Northeast Asian port industry. This system is composed of integrated information system and EDI document exchange system according to the special quality of user's request information. And in order to prove its feasibility and validity, the case study sailing from Shanghai to Busan has been applied to this study.

This paper aims to identify the problems of incentives and find a solution to them by empirically analyzing the port incentives and the development of cargo volume. The current method of paying performance incentives and cargo-increase incentives makes it is possible for shipping companies to get the maximum incentives just by regulating cargo volumes without increasing them. Since the processing volume of transshipment cargo of the Busan port is over the volume eligible for the maximum incentive determined by the tie-up of shipping companies, the transshipment cargo can decrease. The incentive of the Busan port based on the cargo record and increase does not affect the increase of transshipment cargo, only to suffer a loss, and thus a new incentive system is needed that does not allow shipping companies to regulate cargo volumes. Based on the result of this study, We have to apply the even-handed incentive rule which pays the incentive for the cargo volume of the pertinent year with the unit price per 1 TEU to avoid the chicken game among the ports.
