A the circumstances surrounding world ports have changed rapidly, Port competition to attract more cargoes is increasing fiercely. Especially, fierce competition to attract the increasing container cargoes has caused main container ports not only to invest enormous fund to modernize its port facilities but also to improve efficiency in port operation and management. But, it is hard to buila differentiation strategy with general port operation according to investing continuously enormous fund into main ports. In this situation, port marketing like 4P mix is of the immediate necessity and in this point, this paper estimated Brand Equity that have risen the core ability of marketing strategy, to transshipment port using Conjoint Analysis. In this analysis result, this paper shows that the brand equity of port significantly devoted to selection of transshipment port. This means that brand of port can attract considerable transshipment cargo. Then it has to induce customer loyalty for this brand extension.

Nowadays a fierce competition among the liner carriers and thus liner shipping market is characterized by chronic overtonnage and lower freight rates. So this paper's purpose is to analysis the determinant of liner freight rates and to seek for an effective policy and counter measures to stabilize liner freight market and rates.

Ship manoeuvring simulator has been widely utilized for training mariners, for assessing safety, for developing harbour and port, and for designing ships. We discuss a ship manoeuvring simulator which has been newly developed by Korea Maritime University. We briefly explain the computer network system connected with each other, the interface system between computers and navigational instruments, the mathematical model of ship manoeuvring motion in harbour areas, and also ship and terrain modeling technique. Finally using the simulator an experiment of distance cognition and a real time simulation of berthing/deberthing manoeuvre carried out and the results are shown.

It is very important and necessary for safe maneuvering and piloting of a VLCC to know the quantity of her sinkage and trim changes in advance when she enters into shallow water area from deep sea. It is already well known that the quantity of sinkage and trim of a vessel change when she navigates between the sea areas of different depths. In this paper, the authors induced five mathematic formulas to compute the quantity of hull sinkage and trim changes arising from the different conditions and speeds of vessels and sea depth. Also they checked and examined the conditions of 131 VLCC class vessels with the over all lengths between 200 to 360 meters and evaluated mean values of Cb, Lpp/B, Lpp/dm, the trim and mean draft(dm) of them according to the different groups of length and loaded conditions. Using the calculating math formulas and loaded conditions, the authors math tables to find the quantity of hull sinkage and trim changes due to the different size, condition and speed of vessels and the depth of sea.

The maneuvering indices K for ship's turning ability and T for ship's course keeping ability are very important values to evaluate the maneuvering chanacteristics and the motions of a vessel. When a vessel is built in the shipyard they carry out many kinds of sea trials including Z test trials to compute the numerical values of maneuvering indices. They carry out Z test during the sea trial period but they generally make only the graphs of heading angles showing the first, second and third overshoot angle without calculating the numerical values of indices K and T. They normally do not calculate the numerical values of K and T because the calculating and processing methods are a little bit complicated ones and ship owners and the masters of the vessel generally do not require the shipyard to calculate the values and submit the results to them. For this reason, the authors studied on more simplified testing and calculating method and carried out both of the actual sea trial tests of usual Z tests and more simplified tests using the training vessel Saeyoodal of Mokpo maritime university and calculated K and T indices from both trials. The calculated values from both trials are coincided with each other very well and the results were good and satisfactory.

The flow zone through jets are used in evaluating the environmental and constructional effects of navigation on the Kwangyang navigation channel. It is relies on the characteristics of ships and water depth. A numerical model using the momentum theory of the propeller and Shield's diagram was developed in a restricted waterway. Equations for discharge are presented based on thrust coefficients and propeller speed and are the most accurate means of defining discharge. Approximate methods for discharge are developea based on applied ship's power. Equations for discharge are as a function of applied power, propeller diameter, and ship speed. Water depth of the waterway and draft of the ship are also necessary for the calculation of the grain size of the initial motion. The velocity distribution of discharge from the propeller was simulated by the Gaussian normal distribution function. The shear velocity and shear stress were from the Sternberg's formula. Case studies to show the influence of significant factors on sediment movement induced by the ship's propeller at the channel bottom are presented.

As potential of oil spill accident in Busan area is growing with an increase of trade and marine traffic, it become important to provide a realistic and practical response plan to address spilled oil effectively. The authors make a most probable scenario of spill accident to investigate an seasonal applicable response techniques. As a result, it is found that mechanical recovery and/or shoreline clean-up operation are required at the eastern shore of Taejongdae in spring and autumn. In summer, since spilled oil moves and contaminates a lot of sensitive areas in Suyeong Bay, a prompt action is required to mechanically contain and recover as much oil at sea surface as possible, at the same time shoreline counter-measures are commenced. In winter with off-shore wind, no action will be required because there is no risk of oil migration to shore. In addition to mechanical recovery and shoreline clean-up, the use of concentrate dispersant can be an primary option especially in spring and autumn as there is less possibilities to contaminate sensitive areas and sufficient deep waters. However, special care is taken to select response options according to the weather condition at the time of spill.

This paper aims to apply a supply chain modeling and its analysis framework to the supply chain in the port industry. The simulation approach serves two purposes: to model a supply chain network in quantity approach and to evaluate its supply chain performance based on proposed strategies. Through the modeling works to improve the performance, the components of simulation model such as input model, strategy model, operational policy model and performance model in port supply chain were identified. The effects of various strategies can guide the way to administrate the supply chain in the different objectives.

Korean government, port and logistics companies have made a lot of effects t exchange electronic documents between themselves and their partners. As a result of it, Korean Electronic Data Interchange(EDI) standards were make by the Korean Electronic Data Interchange for Administration, Commerce and Transport(EDIFACT) committee and the standards have been used by companies and governmental organizations in Korea. However, Korea port and logistics EDI system is based on Value Added Network (VAN) and a VAN company has monopolist right to relay EDI documents to Ministry of Maritime Affairs & Fisheries(MOMAF) and Customs Service. Therefore it leads to a lot of problems such as inconvenient software, expensive transmission fee, insufficient improvement of business process and the difficulty of connection with the in-house systems of user companies, To solve these problems, United National Centre for Trade Facilitation and Electronic Business(UN/CEFACT) and Organization for Structured Information Standards(OASIS) are aimed to progress for eXtensible Markup Language(XML) and Internet-based Electronic Business Extensible Markup Language(ebXML) electronic commerce framework. This research is trying to derive an conceptual ebXML model based e-Business for port and logistics industry. Especially, for improving extant problems in the port and logistics industry, this research proposes the Information Strategic Planning(ISP) and Proof of Concept(POC) for ebXML system.
