The shipping business industries which are the transport and logistics intensive in Busan, have been small sized and scattered in many areas, that is why they could not create a synergy effect utterly. Because of the need to develop the shipping business cluster complex in Busan in order to concentrate those industries and attract high value added firms, this study tries to suggest an approach to build the cluster. Firstly, how various shipping business related firms in Busan and capital area demand the cluster complex are searched through questioning survey. Secondly, the gradual scheme to integrate lots of business companies, governmental authorities and educational institutes and global strategy to invite domestic and foreign organizations in Myeong Ji area near to Busan New Port. Thirdly, the expected economic benefits of the cluster construction are calculated quantitatively.

This paper aims at drawing policy schemes to establish marine clusters so as to enhance Korea's global port competitiveness and applying them to its national management for the advancement of national economy through policy suggestions. The research method is an integrated approach(IA) that comprises SWOT Method with strategic approaches, HFP Model enhanced by KJ Method and descriptive deductions. Strategic schemes established for the SPLC are followed by the group of geographical proximity, integration of ICT, expansion of the interchange of ICT & opportunities of ET, integration of ICT services with marine technologies, supply of integrated services in the SPLC and implementation of organizational policies. In order to make a specific implementation of strategic establishment schemes of the SPLC, we need to select a promotion entity. It is advised to establish the joint organization of the public sector and the private sector, which is considered most desirable. In practice, it is to be followed by promoting support schemes of the organizational policy on the level of national management. In order to reinforce this study, further compensative and proactive researches on the offshore sector with marine clusters are required in terms of the development of the high value added 'blue' ocean.

Today's individual firms no longer compete as solely autonomous entities, but rather as supply chain. As such the competitive position of a port is not only determined by its internal strengths but also it is also affected by its links in a global supply chin. In other words, port competitiveness is becoming increasingly dependent on external coordination and control of the whole supply chain. The main purpose of this paper is to examine how a port embeds itself into supply chain in order to strengthen its competitive position by focusing on Dubai port case. This paper found that Dubai port used three phases-insertion, integration and dominance-as a strategies for how it can embedded into global supply chain successfully. Dubai's global supply chain strategies give some implications for the further development of the Port of Gwangyang. First, the Port of Gwangyang should fully utilize symbiotic relationship with Gwangyang free Economic Zone. Second, the integration between Korea Container Terminal Authority and GYFEZ can be recommended for fast decision-making and providing a one-stop-service. Finally, Gwangyang should pursue an aggressive supply chain strategy, aims at dominance in the regional port network through port alliance with small and medium ports in neighboring area.

Following the collapse of Hanjin Shipping, building a strong maritime cluster is one of the policy measures for the re-construction of the Korean shipping and shipbuilding industries. Thus, the purpose of this study is to develop a policy alternative for building a maritime cluster. Using Porter's diamond models, we analyzed the Imabari maritime cluster of Japan, which is characterized by cooperation between key industries, such as shipping, shipbuilding, shipbuilding equipment, and finance. The Imabari Maritime Cluster is equipped with complete domestic demand conditions and related supporting industry conditions. Although the strengths of the production conditions include excellent family-based management and strong support from regional administration and banks which develops independency among cluster members, the weak points include the absense of robust port services and difficulty in recruiting young talent in small and medium-sized cities. We can confirm that the company's strategy is focused on stable management, rather than a short-term view.

Clustering is one of the most important unsupervised learning methods that clusters data into homogeneous groups. However, cluster centers tend leaning to high density clusters because clustering is based on the distances between data points and cluster centers. In this paper, a modified clustering method forcing cluster centers to be apart by introducing a center-scattering term in the Fuzzy C-Means objective function is introduced. The proposed method converges more to real centers with small number of iterations compared to the original one. All the strengths can be verified with experimental results.

The purpose of this paper aims at contributing to the national economic development through global competitiveness enhancement by marine finance's hub and marine logistics cluster by finance specialization and finance support as a creative-type service industry in global shipping port logistics. This study adopted the integrated approach and applied it to policy implementation to achieve the effectiveness. Creative-type marine finance development stages as a tool of policy implementation and the guide line for the time of policy implementation are followed by Stage 1(Construction & Growth Policy) for 2013~2016, Stage 2(Forstering & Activation Policy) for 2017~2019) and Stage 3(Continuous Development Policy) after 2020 until its completion. Korea has the inferiority over the competitiveness in global marine finance and needs a strategic approach to secure the liquidity of marine finance; interim, Islamic finance has been come to the force as a new alternative in financial transaction being accompanied by a spot transaction since the crisis of global finance. In order to create a potential slack of Korea in marine finance practice, in addition, this study suggests a consortium with the circle of Islamic finance as a clue of an easier policy implementation at the beginning stage.

In port management, the scale of facilities and port layouts are major factors characterizing the port, which influence port economics and productivities continuously through the port operation. Grouping ports in certain region by their characteristics could be used as the principal informations to establish national policy for port development or investment and also to analyze the competitiveness between ports. Currently Korean ports are divided into two groups such as the local port and the designated port containing foreign trade port and coastal port under the Korean port law. These divisions seem to be used for port administration as the matter of convenience but some qualitative grouping is needed for research of port problems. In this paper, 20 major Korean ports were clustered by the similar characteristics using Fuzzy C-Means and found to be classified 8 qualitative groups.

The Seosan-Daesan Port is a representative trade port in Chungnam, and has the sixth largest total cargo throughput and the third largest oil cargo throughput in Korea. However, research on this port's development is lacking relative to that for Busan Port, Incheon Port, and Gwangyang Port, and no study exists that suggests the direction of the development strategy for Seosan-Daesan Port. This study discusses the future role of Seosan-Daesan Port in preparation for a rapidly changing future and the development strategy that should be established. Using the AHP, a development strategy is provided for Seosan-Daesan Port from short/mid-term and long-term viewpoints for three aspects: operation activation, infrastructure construction, and policy support. Operation activation is chosen as the most significant factor from a short/mid-term viewpoint, whereas infrastructure construction is recognized as important from a long-term viewpoint. Specifically, from a short/mid-term viewpoint, sustainable container cargo attraction, multipurpose dock construction, management pier construction, and opening of international passenger ferry lines are important factors while from the long-term viewpoint, hinterland construction, petrochemical industry cluster construction, automobile industry cluster construction, and management improvement system are important. Establishing action plans for each strategy and a cooperative network for sharing goals and strengthening cooperation is necessary.

Clustering is one of the most well-known unsupervised learning methods that clusters data into homogeneous groups. Clustering has been used in various applications and FCM is one of the representative methods. In Fuzzy C-Means(FCM), however, cluster centers tend leaning to high density areas because the Euclidean distance measure forces high density clusters to make more contribution to clustering result. Previously proposed was density-independent clustering method, where cluster centers were made not to be close each other and relived the center deviation problem. Density-independent clustering method has a limitation that it is difficult to specify the position of the cluster centers. In this paper, an enhanced density-independent clustering method with an additional term that makes cluster centers to be placed around dense region is proposed. The proposed method converges more to real centers compared to FCM and density-independent clustering, which can be verified with experimental results.
