The aim of study is to develop a dual driven ship berthing/deberthing system with $360^{\circ}$ steerability. A large ship used bow thruster, side thruster and pod propulsor etc. when approaching to a pier. But as marine leisure boats become large-scaled, the number of accidents is recently increasing what caused a ship to crash into a ship and a ship to crash into mooring facilities during berthing/deberthing on a marina. To solve the problem, the control responsiveness of a joystick connected with two motors and a propeller was checked and torque was increased by the electromagnetic design of magnetic gear. A sea trial test was carried out to investigate a performance of the developed system in the real sea.

QR Code can save much more information than 1D Bar Code and encode various types of information. As it takes less general cost than high priced RFID, it can be recognized through smart-phone without any special facilities. Despite these strengths, QR Code is just used by general people for their daily life service, while 1D Bar Code is applied in all kinds of industry like sales, distribution, production management, quality management and so on. And RFID is also used in many industrial field like harbor and distribution area. The range of QR Code's usage is getting broad but still restrictive. So it is required to make new organized system. Therefore, this research suggests that Applying QR Code in the SCM. Connecting QR Code with SCM, it secures space for data's movement. And it helps not only rise the speed and accuracy of data flow but also reduce logistical cost.

The systematic criteria and rational standard for site selection of marine recreational floating architecture are in urgently need in respect of structural safety, use of facilities, economics of construction and management, relationship with surrounding areas or cities and impact on marine environment. Nevertheless, at present, there is not any study nor guideline for site selection of marine recreational floating architecture which is now being planned and elected at many places of a body of water such as river or coastal area all over the country. Therefore this study is to propose a systematic process and a rational criteria and guideline for site selection of marine recreational floating architecture. Especially the results are suggested in forms of diagrams and tables in order to be utilized so easily by related local governments and individual enterprises.

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.

The operations of the warehouses are labor intensive. Automation of the warehouse is made by efforts to shorten the work time and reduce the cost according to the change of the production form of the company and the buyer's demand. Storage warehouses vary in size and shape, and equipment and facilities used in storage warehouses vary according to purpose and use. In order to automate storage, it is necessary to introduce an operating system, which varies depending on the type of equipment and operation policy. In this paper, we review the requirements for the automation of small and medium-sized storage warehouses, and classify the equipment selection and operating system options into effective scenarios to introduce an effective automation system. Therefore, simulation is performed for each scenario, and the effect of automation is examined, and the effect of automation is verified through economic analysis through cost for automation introduction.

Aid to Navigation (AtoN) is the artificial facilities to facilitate the ship's safe navigation using light, shape, color, sound, and radio waves. IALA has developed and operated the educational course for expert groups for the design, deployment, and management of AtoN. Also, maritime educational institutes have operated various educational courses for safe navigation through the ship's operation and ECDIS curriculum for seafarers. However, education using the AtoN Simulator System is needed to prevent marine accidents caused by misunderstanding of the AtoN according to various topographical, environmental, and maritime traffic environments. In this study, the existing ship handling simulator and AtoN simulator were applied to develop educational modules for accurate understanding and application of AtoN in various environments, enhancing the quality of education from the existing theoretical point of view and improving practical use to maximize educational efforts.

Until now, korean aquaculture industry has been grown largely from a quantitative viewpoint. However, an increase of quantity has caused lots of problems producing a derived effect recently. Nearly 82% of korean aquaculture farms had been installed mainly at inshore of the southern sea and also sewage, factory wastes, high density of fishcage at the limited area and autoinfection have deteriorated inshore fisheries. The offshore have been on the rise for the solution to these problems since it has clear seawater reduces the environmental pollution with much current. As a matter of fact, the existing inshore fishcage facilities have trouble advancing to the offshore due to the rough environmental conditons such as a high sea, strong currents etc.; therefore, it is necessary to develop a new cultivating equipment fit the open sea conditons. In this research, the theoretical study and experimental analysis have been carried out for the fishcage design of the structure which is able to use at the open sea.
