In this paper, we propose a system that extracts licence plate and recognizes numerals in the licence plate. The candidate area of licence plate is extracted using the improved IAFC(Integrated Adaptive Fuzzy Clustering) fuzzy neural network. And the morphological filters are used to reduce noise from the extracted licence plate. The extracted licence plate is standardized using Hough transform and geometric transform. Backpropagation neural network is used to recognize numerals that are separated using the projection technique.

NSW in Australia is famous for beautiful beaches and water activities. There are now almost 450,000 people who hold a NSW power boat driving licence and 200.000 registered boat owners. The popularity of boating continues to grow with licence and registration figures increasing by 3-4 per cent each year. This is a survey about the guide book for boating licence in NSW. This study outlines the essential information such as the types of licence, registration of vessels, choosing the right boat, maintain vessel, safety equipment and preparing for a safe boating trip. In addition, it touches the technical side like boat handling, water traffic rules, navigation markers, emergency and the ways to avoid them. Recently, more and more people are interested in boating. It forms an important part of recreational and tourism activities. To manage these demands effectively and to provide the orderly and safe leisure hours, it is necessary to induce more organizational and serviceable boating licence system.

The health of licence holders (flight crew members and air traffic controllers) is recognized as an important element of aviation safety. The medical emergency symptoms that occur during the flight duty period without prior notice can interfere with human performance capabilities and threaten aviation safety. To prevent this, ICAO has been required to conduct a periodic medical assessment process of licence holders including routine analysis of in-flight incapacitation events and medical findings during medical to identify areas of increased medical risk and continuous reevaluation of the medical assessment process to concentrate on identified areas of increased medical risk. The supply and demand of licence holders have become a major issue due to the increase in air traffic around the world, and the pilot retirement age has been extended to 65 years. But, there is no significant change in the aviation medical assessments process. The follow up of the result of medical examination discovered through aviation medical examination is a very important part, but it has not been properly implemented, and the sick leaves and medical inflight incapacitation reporting system should be improved. The management of health risk factors for licence holders must be implemented to prevent aircraft accidents or aviation safety problems caused by health problems. In this paper, we propose the development plan and concrete improvement plan of the health risk management system of licence holders in Korea in terms of aviation safety.

Background: This study aims to conduct curriculum analysis on health management schools focusing on relationship with licence and certification in Republic of Korea. Methods: Possible employment field, licence and certification as well as curriculum were collected from the home page of 30 health management schools. The subjects and credits of curriculum were analyzed using descriptive statistics. Main subjects by areas were drew using categorization and ranking within qualitative methods. Comparative analysis was conducted for checking relationship between main subject and possible employment field, licence and certification. Results: First, major employment fields after graduation were public health officer, general hospital and clinic, and National Health Insurance Service. Possible licence and certificate were hospital administrator, medical recorder, health education specialist, and medical insurance specialist. Second, total graduate credits were 133.9 including 79.0 for major education, 30.5 for of general education, and 30.5 for elective courses. Third, main subjects were reviewed by areas including basic medicine, health management, hospital business & management, medical records & information, insurance billing & assessment, healthcare marketing & tourism, and health education. There were highest number of subjects on health education area among 8 categories. By subjects, many health management schools open health law, medical terminology, introduction to public health, and biostatistics. Relationship between main subjects and possible employment field, licence and certification in health management schools was strong. Conclusion: It is necessary to review curriculum and for improving educational quality in health management schools. Also, development of curriculum standards for courses in health administration and introduction of accreditation system can be considered.

This paper describes a method that extracts the region of car-licence plates in color images of private and commercial cars. To extract car-licence plates, we use the feature that car-licence plate regions have regular colors according to the kinds of cars. In this paper, we propose the method that combines H component of HSI color model and Q component of YIQ color model. To improve efficiency of the process, we cxplore lines ill a car image by a regular interval in a bottom-up style. As a result, the extraction rates by only H-component. only by Q- component. and by combined Hand Q, are 53.6%, 82.1%, and 94.6% respectively.

The long-existed licence system which has acted as one of the strong barriers to entry in the ocean shipping market in Korea is supposed to repeal in the near future. As a result, competition among the different sizes of firms which are operating under regional shield by means of the licence will be intensified. The main objective of this paper is to estimate the degree of economies of scale and economies of density for various firm sizes. For the successful estimation of economies scale and economies of density, translog cost models are developed and estimated through SURE technique which was suggested by Zeller (1963). The major findings are as follows ; All shipping firms in the sample exhibit economies of scale and density. Even small size shipping firms under licence system, they show substantial economies of scale contrary to the wide-known idea that small-size firms are subject to diseconomies of scale. For the ranked firm sizes according to owned deadweight tons, the degree of economies of scale decreases as the firm sizes are larger and larger. The degree of economies of density moderately declines from the smallest to the firm size of 30-60 thousand deadweight tons and sharply rise thereafter. And the large shipping firms with over half-million deadweight tons exhibit high economies density compared to other sizes of firm. If follows that the larger firms have great advantage in competition if the licence system is abolished.

This study investigated the changes of chlidcare centers' status, establishment and licence standards, and childcare publicness 20 years after Infant and Early Child Care Act(IECC Act) was enacted in Korea. For this purpose, we examined the trends of establishment status and explored the changes of licence standards sorted as location, type, size, area, indoor-outdoor facilities, playgrounds, in accordance with the revision of the IECC Act from 1991 to 2013. In addition, we organized the concepts and standards for the public service of childcare. Finally, we presented some problems found in the IECC Act and the implementing rules about childcare center's establishment and licence standards. We provided some suggestions in order to improve the institution and ensure the publicness. Through these efforts, we tried to contribute the improvement of the quality of childcare in Korea.

The readability and the visuability are very significant when the letters or figures are displayed as static visual information. Not only is the beauty of the body type character(small letters) important but the display type character(large letters) should also be read easily, quickly and precisely. The issue regarding the readability in terms of perception of information has been raised continuously for all kinds of small signage and billboard, etc., which are written in display type within our everyday life. Among the various kinds of small signage and billboards the car licence plate is well known. Among all the possible factors that would have made an impact on the readability of licence plate, this paper focused on the effects of arrangement of character(letters and figures) and contrast of colors for the readability of licence plate using the within-subject analysis. The statistical analysis results in error reading rate, the character arrangement were significant but the color contrast(green/white, white/green, blue/white, white/blue, black/yellow) was not, No interaction was found.

In this paper, a system which can effectively recognize the plate image extracted from camera set on a moving car is proposed. To extract car licence plate from moving vehicles, multiple candidates are maintained based on the strong vertical edges which are found in the region of car licence plate. A candidate region is selected among them based on the ratio of background and characters. We also make a comparative study of recognition performance between support vector machines and modular neural networks. The experimental results lead us to the conclusion that the former is superior to the latter. For a better recognition rate, a simple method combining the support vector machine with modular neural network where the output of the latter is used as the input of the former is suggested and evaluated. As we expected, the hybrid one shows the best result among those three methods we have mentioned.

Human Resources Development of Korea has been practicing performance evaluation for occupational qualification licences in environmental sectors that include water, air, and wastes management, but not soil. The purpose of the study was to improve overall quality of the national qualification test in the soil sector to better train applicants based on National Competency Standards (NCS), which is designed to emphasize site-specific conditions and knowledge. This study systematically analysed the current licence test in the soil sector with respect to qualification units, performance criteria, knowledge, techniques, and attitude as described in NCS. Furthermore, test evaluation was conducted to examine the validity of the revised licence test. The test results indicated the revised test method would bring positive outcomes to the related industry. Upon the reviews and amendments by the field experts, the result of this study could serve as a framework to the development of more robust and reliable licence test.
