The LORAN system had been used widely and it was an essential navigation aid for ships in the ocean until the GPS is adopted actively. In particular, it was essential functionality for the ships to sail the oceans. According to the advancement of industry, however, the current accuracy of traditional Loran is insufficient for the utilization of harbour approach, land navigation, and the field of survey and timing. Therefore it is necessary that the study on the improvement of the positioning accuracy of Loran. The one of the improving methods is to measure and compensate the propagation time delay between the transmitter and user's receiver, which is called as additional secondary factor (ASF). In this study, we measured the ASF between the Pohang master transmitting station (9930M) and four points where locate within 33 km apart from the transmitting station, using the measuring technique of the absolute time delay without a time of coincidence (TOC) table. As the result of measurement, the ranging error caused by the propagation delay was about 210 m at 33 km, however it can be reduced up to 40 m with ASF compensation.

This paper describes statistical parameter estimation to calculate collision probabilities between Mokpo Harbor Bridge and passing vessels. At first, we obtained AIS (Automatic Identification System) information from passing vessels, then after, analyzed the lateral distributions of vessel tracks and estimated the mean and the standard deviation for the distance away from bridge center, the passing course and the passing speed. The analysis results of track distribution for the distance away and the passing course are shown as normal type, otherwise the speed distribution shown as two kinds of different normal type. In addition, we testified that the usefulness of estimated parameter values through the relative comparison between the track distributions and it's normal probability distributions.

In this study was carried out on the proper number of cadets and the improvement of educational environment that can ensure effective practice on board a training ship. In doing this research, basic data had been obtained from some of the written interviews done with some apprentices and instructors on education, and survey findings on the dimensions of the training facilities and areas available to apprentice in the current training ships. The concepts of ergonomics have been adapted to this study also, in order to increase its reliability. On the basis of what has been discussed just above, we have suggested a navigation integrity consol for deck apprentices and a training room for the operation and maintenance of shipboard machinery for engine apprentices, together with providing a suitable number of cadets that can be accommodated for practice altogether in a given situation.

High speed marine vehicle, such as semi-planing, planing craft have been developed recently. These ships paid attention to the resistance characteristics, especially in high speed region. Model test method is divided to two equipment greatly, first 'Towing tank', second 'C.W.C.'. It is difficult to estimate a resistance characteristics for high speed boat. because these are made for low speed ship. This paper suggests a new model test method and system. This is real sea model test and it's comprised of eight part. Firstly, This method is tested at C.W.C that is possible to using in real sea model tes using low speed boat modelt. And then, Real sea model test and CFD calculation are performed and compared with tow way used high speed boat model. It can be a good way to estimate a performance for high speed boat.

Mathematical model of maneuvering motion for a Mobile Harbor is established and versatile applications to the special situations of maneuvering are attempted. The Mobile Harbor in this research has twin Azipod thruster and twin bow thruster. In order to predict the maneuverability of Mobile Harbor, a mathematical model was developed on the basis of MMG model, and some model test results were adopted for the simulation of Mobile Harbor. As a result, the turning motions of the Mobile Harbor were successfully calculated. and the optimal berthing system was completed.
Brand Personality Scales and Images of Haeundae

Container port development in Korea seems to be based on the policy of balanced regional development rather than demand and supply theory. The problem of overcapacity and low utilization faced by several ports such as Kwangyang, Ulsan New Port and Phohang Youngil New Port can back up this. Furthermore as some ports are located closely sharing the same domestic hinterland the revitalization of the ports is not easy resulting in wasting resources with both regional and national aspect. This study, therefore, aims at providing an empirical results for the container port classification of the 5 ports such as Busan, Kwangyang, Incheon, Pyeongtaek and Ulsan. For this several time series data for the ports such as transshipment containers, import and export containers, origin and destination countries, and local origin and destination are analysed. Based on the results of the analysis the 5 container ports are classified together with their practical roles, and the functional overlap of the port including Phohang was analysed.

In order to achieve a sustainable competitive advantage in the expanding maritime transportation market, most shipping companies are making every effort to reduce transportation costs. Likewise, the car shipping companies, which carry more than 80% of total car import and export logistics volume, also do their utmost for transportation cost saving. Until now many researches have been made for efficient maritime transportation, but studies for car shipping companies have rarely been made. For this reason, this study has tried to develop a maritime transportation planning support system which can help to save logistics costs and increase a competitive power of car shipping companies. To this end, instead of manual effort to solve the routing problem of car carrier vessels, this study has proposed a genetic algorithm. The performance of the genetic algorithm will be evaluated by comparing with the optimal solution of integer programming model.

In this study, we examine features of marine transport environment which shipping companies are facing, analyze the ability to cope with this environment, and present the relationship between the ability and business performances. Then, we demonstrate that diagnosis of shipping environment in the global marine transport environment and preparing to it is very important. Also, we present that the ability to prepare is the main factor to decide the competitive power of the company. This study has a meaning in that the importance of business activities related to environment such like diagnosis of environment, analyzing, management, adaptation, and prediction is presented. Besides, the value of this study is that we analyze the relationship between corresponding ability, strategic execution process and business performance in general.

About ten years have passed since the rules regarding establishing the Inquiry Counsels Association in the Act on the Investigation of and Inquiry into Marine Accidents were founded in 1999. In recent years, we expect to do the inquiry aid of a person involved in a marine accident, when the government enacted new regimes to better protect the rights of social minorities. But despite such rules regarding establishing the Inquiry Counsels Association, the government did nothing to found the Association for the last ten years. Especially, it is necessary a pivotal figure connecting to a similar work boundary, because persons qualified for an inquiry counsel are various. The authors think that the establishment of the Inquiry Counsels Association plays key part in resolving these problems. Therefore this study focused on the establishment of the Inquiry Counsels Association.
