IMO introduced e-Navigation concept to improve the efficiency of ship operation, port operation, and ship navigation technology. IMO proposed sixteen MSPs (Maritime Service Portfolio) applicable to the ships and onshore in case of e-Navigation implementation. In order to meet the demands of the international society, the system implementation work for the Korean e-Navigation has been specified. The Korean e-Navigation system has five service categories: the S2 service category, which is a ship anomaly monitoring service, is a service that classifies emergency levels according to the degree of abnormal condition when a ship has an abnormality in ship operation, and provides guidance for emergency situations. The navigation safety module is a sub-module of the S2 service that determines the emergency level in case of navigation equipment malfunctioning, engine or steering gear failure during navigation. It provides emergency response guidance based on emergency level to the abnormal ship. If an abnormal condition occurs during the ship operation, first, the ship shall determine the emergency level, according to the degree of abnormality of the ship. Second, an emergency response guidance is generated based on the determined emergency level, and the guidance is transmitted to the ship, which helps the navigators prevent accidents and not to spread. In this study, the operational concept for the implementation of the Korean e-Navigation system is designed and the concept is focused on the navigation safety module of S2 service.

The autopilot system targets decreasing labor, working environment, service safety security and elevation of service efficiency. Ultimate purpose is minimizing number of crew for guarantee economical efficiency of shipping service. Recently, being achieving research about Course Keeping Control, Track Keeping Control, Roll-Rudder Stabilization, Dynamic ship Positioning and Automatic Mooring Control etc. which compensate nonlinear characteristic using optimizing control technique. And application research is progressing using real ship on actual field. Relation of Rudder angle which adjusted by Steering Machine and ship-heading angle are non-linear. And, Load Condition of ship acts as non-linear element that influence to Parameter of ship. Also, because the speed of a current and direction of waves, velocity and quantity of wind etc. that id disturbance act in non-linear form, become factor who make service of shipping painfully. Therefore, service system of shipping requires robust control algorithm that can overcome nonlinearity. In this paper, Using GA algorithm,design autopilot system of ship that could overcome the non-linear factor of ship and disturbance and examined result through simulation.

The purpose of this study is to extract the factors affecting service quality, customer satisfaction, and customer loyalty and to find out what effect service quality & customer satisfaction, service quality & customer loyalty, and customer satisfaction & customer loyalty respectively. The results of hypothesis testing through regression analysis showed that the hypothesis between service quality of ship management company and customer satisfaction was accepted in terms of all 5 service quality dimensions of tangibility, reliability, responsiveness, assurance and empathy. Also, the hypothesis between service quality of ship management companies and customer loyalty was accepted in terms of all 5 service quality dimensions of tangibility, reliability, responsiveness, assurance and empathy. Lastly, the hypothesis between customer satisfaction and customer loyalty was accepted.

The purpose of this paper is to find out the applicability of relationship marketing concept in a professional ship management context primarily on ship management service business. The dramatic growth in ship management industry leads to the intensified competition among professional ship management companies in the world. Thus they have tried to find out ways of ensuring competitiveness to be a market leader in this industry. The fundamental base of marketing is that it involves exchanges. Professional ship management involves a series of transactions and exchanges between client and ship manager. Ship management companies will ensure competitiveness by applying the concept of relationship marketing to real practices.

These days, the cruise tourist industry is one of the most dynamic and fastest growing components of the leisure industry in the world. Therefore, the cruise ship with ubiquitous technology is expected to enhance the operation efficiency of the ship. It can also provide valuable addition to the ship's service as well as high quality of life to crews and passengers. Since a large number of passengers are dwelling in cruise ship, all passengers are not easy to use ship's facilities, such as restaurants, fitness center, swimming pool and spa at anytime they want. In this paper, passenger service system in ship environment is tested in similar environment and under ship operation condition. We have proposed three applications of ubiquitous technology using Zigbee communication and LabView program.

Because shore(ship) to ship(shore) communication service via INMARSAT pay expensive cost, satellite service typically use two stage service that land users dial up LES(Land Earth Station) for sending or receiving message. In order to send and receive message, land users must maintain online state with LES on dedicated line. Also, two stage INMARSAT communication service must consume long time that processes step by step. In case of large company, they have own communication system, but small companys communicate simple messages with only telex. This paper describes the design and implementation of an integrated communication services via INMARSAT-C. This system uses inexpensive INMARSAT-C for transmission between ship and land. Because this system provides web and E-Mail interface, users send and receive messages easily and quickly. This system provides most users with inexpensive and easy communication facilities between ship and land.

The routes of coastal passenger ships are important in the light of both economic and social view point. Islands around the Korean peninsular can be actually dominated by linking them with land by the ships. The service quality of the route is not high enough to satisfy habitants in the islands. The income of the service-users is increasing so that they expect better service in terms of ship's speed and cabin. The reality is not, however, good to motivate ship-owners to replace aged ships with new and large ones. The situation is caused by low passenger-fare and inefficient management. Therefore the fare should be raised and the fare system should be innovated. And the number of passenger ship companies should be reduced from 42 to 20 by merger and acquisition.

From the day of luxurious inland river cruise ship started in Chongqing, China, the controversy is continuous; some people think those luxurious cruise ships on inland river might reduce the experience to enjoy the scenery of the Three Gorges, while some people think, which could improve the experience. In the study, the service facilities provided by luxurious inland river cruise ship will be evaluated by Pre-Post comparison based on IPA methods. After a review of the service facilities provided by luxurious inland river cruise ship running on Three Gorges areas. The tourists who would take the trip were asked to fill an questionnaire to examine the desired service facilities performance, which represents the highest level of the service facilities of the cruise ship that is expected by customers. After the trip, they were asked again to fill another questionnaire to examine the importance of service facilities and the performance of service. Pre-Post comparison would be examined to tell whether there is any change between pre and post experience. IPA would be used to evaluate the service facilities provided by inland river cruise ship. At last, some strategic suggestions to the development of inland river cruise ship are made.
