The objects of this study are to consider the current features and the development process of the utilizing system of aquaculture farms in Japan, and to suggest the theoretical basis for improvement of aquaculture system of Korea in the future through the analysis of background of the liberalization theory proposed recently. The aquaculture-fishery system of Japan was begun from the Meiji Era Fishery Act and New Fishery Act of the World war II. A small sum of fishery fee is paid to the fishery cooperative having fishing rights for securing fishing area newly, because the aquaculture of Japan belong to fishery cooperative not individual ownership of union membr of cooperative society, the other words, cultivation fisheries household. In case of Korea, there are several differences with Japan as follows; almost cultivation fisheries household has a individual license, the lisence of fishing rights are recognized as an article, the license of fishing lights are able to do sale. Therefore, it is needed to paid a lots of money for securing fishing area newly. On the other hand, advanced countries in the marine aquaculture such as Norway have reached the stage where the managing abilities of marine aquaculture are similar to those in the manufacturing industry. And the number of large scale aquaculture farms with developed technologies and advanced marketing strategies in those countries is increasing. Considering that the marine aquaculture in Japan under the similar fishery systems of Korea has developed the state-of-the-art management skills or lead to large scale management, it is difficult to expect the decrease in the production costs under the small scale family business in Korea and this will lead to the decreasing competitive advantage over the imported seafood. Therefore marine aquaculture in Korea needs to increase the economy of scale to acquire the competitive advantage.

The old sources of competitive edge and value added were land, labor, and capital. In today's knowledge-based economy in the 21st century, technology is attracting attention as a new engine of growth. That paradigm shift of world economy has resulted in the global spread of technology transfer and the gradual increase of trade of intangible goods including patents and know-how as well as tangible goods in international trade. An international license agreement is a representative form of technology transfer. In license agreements, the providers of technology keep their ownership of technology, allow the implementation of technology to the users of technology only for a certain period of time, and receive loyalty as a reward. Economic profit through such technology trade can be realized with the smooth implementation and termination of agreement. International license agreements are different from sales contracts, which represent international business transaction based on mutual obligation, in many aspects in that they target intangible goods of technology and aim for rent for a certain period of time. This study thus set out to examine issues that could be controversial in the main and individual obligation of the parties in international license agreements and provide implications helpful for the prevention of disputes in advance.

License plate recognition system for an exclusive bus-lane is made of 5 core parts which are vehicle detection, image acquisition individual character extraction, character recognition and data transmission. Among them, the accuracy of license plate extraction can bring effect significantly to the accuracy of a whole system recognition rate also the more exact extraction of license plate is required in various weather and environment conditions. Therefore in this paper we propose a plat extraction algorithm that makes pyramid structure to reduced the extraction processing time binarizes plate's template region using adaptive thresholding extracts candidate region containing plate, and verifies a final region using plate character distribution characteristics among the candidates. Experimenal results were exactly extracted the license plate region by using proposed method to the image obtained in an exclusive bus-lane with various weather and environment conditions.

We implement automobile license plates recognition system. These days automobile license plate recognition systems are widely used for tracing stolen cars. managing parking facilities, ticketing speeding cars, and so on. Recognition systems largely consist of three parts plates extraction, segments extraction, and segment recognition. For plates extraction, we measure the degree of inclination of plate. We use filters that extract only the horizontal components of the front of an automobile to measure the degree of inclination. For segment extraction, we trace the change of the number of blocks that consist solely of foreground pixels or background pixels as the horizontal scanning line moves along upward. For recognition of each individual letter or digit, we devise a variant of template matching method, called comparative template matching. Through experiments, we show that comparative template matching is less prone misled by noises and exhibits higher performance compared to the traditional method of template matching or histogram based recognition.

Recently, the color of vehicle license plate has been changed from green to white. Thus the vehicle plate recognition system used for parking management systems, speed and signal violation detection systems should be robust to the both colors. This paper presents a vehicle license plate recognition system, which works on both of green and white plate at the same time. In the proposed system, the image of license plate is taken from a captured vehicle image by using morphological information. In the next, each character region in the license plate image is extracted based on the vertical and horizontal projection of plate image and the relative position of individual characters. Finally, for the recognition process of extracted characters, PCA(Principal Component Analysis) and LDA(Linear Discriminant Analysis) are sequentially utilized. In the experiment, vehicle license plates of both green background and white background captured under irregular illumination conditions have been tested, and the relatively high extraction and recognition rates are observed.

The purpose of this study was to propose appropriate requirements to obtain a pilot's license in order to improve the safety of pilotage related to a survey of experts involved with pilotage. The survey has been conducted by experts from stakeholders in various fields. To suggest requirements for the license, a hypothesis test has been conducted. It turns out that onboard experience with higher gross tonnage is eligible for pilot. Secondly, it is required to have onboard experience of more than one year as a captain, within 5 years from the date that the individual takes the pilot's written test, with 5 years onboard experience as a captain. Lastly, if personality and aptitude tests are added to the requirements to obtain a pilot's license, the safety of pilotage will increase rapidly.

The National Competency Standard (NCS) is being implemented on the basis of a college of higher education. The college offers intensive education by organizing three areas of knowledge, skills and attitudes so that students can perform their full capacity at the same time as graduating in industrial field. Health Department at the College has been training for a variety of medical personnel, including medical technician regions. Especially, the medical technician and medical sector must be licensed to work in the medical field. Therefore, passing the national examination license is a prerequisite for employment. In this study, the health law scores of the third grade students (about 200 students) of the radiology department of D College were analyzed at weekly intervals. The weekly score acquisition can be predict the pattern of student class achievement of individual students. Furthermore, these results can predict the possibility of passing the radiation license examination for individual students.

Some drivers cannot meet the standards for a full driver's license and many countries allow them to drive a vehicle as long as they can satisfy certain conditions. Korea has mainly issued conditional driver's licenses to the disabled only after supplementary devices are attached either in the vehicle or in their bodies. However, it is becoming important to issue a conditional driver's license to other types of drivers, including the elderly as the population ages in the country. This study aims at improving the current practice of issuing conditional driver's licenses by benchmarking various types of conditional licenses in other countries. In particular, various conditions such as time, space, driving speed, road type, vehicle type, and specific individual conditions are compared. Issuing a conditional driver's license to various types of drivers should be beneficial, not only to elderly drivers but also to drivers who cannot live without a vehicle.

In this paper, we introduce a system that detects all kinds of violations at a street intersection such as red light running, speed violation, stop line violation and lane violation by tracking individual vehicles. Two cameras are used for defecting violations. One is an analog camera for real-time tracking and the other is a digital camera for license plate reading. This system is connected to the traffic signal system controller and monitors the red, arrow, yellow and green phases of an approach. Two loops in the road are used to detect vehicle approach and speed. The system takes pictures of all vehicles passing a second loop and tracks the vehicles until they go out a street intersection...
