In order to recognize a vehicle license plate, the region of the license plate should be extracted from a vehicle image. Then, character region should be separated from the background image and characters are recognized using some neural networks with selected feature vectors. Of course, choice of feature vectors which serve as the basis of the character recognition has an important effect on recognition result as well as reduction of data amount. In this paper, we propose a novel feature extraction method in which number images are decomposed into linear combination of eigennumbers and show the validity of this method by applying to the recognition of numeric characters in license plates. The experimental results show the recognition rate of 95.3% for about 500 vehicle images with multi-layer perceptron neural network in the eigennumber space. Compared with the conventional mesh feature, it shows a better recognition rate by 5%.

This paper examines the factors that influence viewers' attitudes toward the public service broadcasting (PSB) system and the license fee. A online survey group was classified into four types on the basis of their expectations and evaluations of public values and demographic characteristics. Subsequentially, the attitudes each type of the viewers displayed toward the PSB system and the license fee were analyzed. The result reveals that young women in their 20-40s have more negative attitudes toward the PSB system than any other groups; those women tend to have high expectations on 'diversity' whereas they show low satisfactions with all the other public values. Additionally, this study attempted to detect factors that affect the attitudes toward the PSB system and the license fee. The important factors was not only the viewers' demographic characteristics but also their expectations and evaluations regrading the public values of PSB.

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.

Background: The problem with current dental hygienist education is that it operates as an education system based on the national examination rather than on a practical basis; thus, graduates have difficulties in practice after obtaining their license. This study aimed to propose a job-oriented curriculum by analyzing the links between the task analysis of Korean dental hygienists and dental hygiene learning goals. Methods: This study performed a relationship analysis based on a second job analysis study of dental hygienists conducted by the Korea Health Personnel Licensing Examination Institute and the learning goals of the Korean Dental Hygiene Faculty Association. Results: Based on the links between the task and learning goals of the dental hygienist, they were classified into six types: 1) tasks listed in the license exam and learning goal, 2) tasks not listed in the license exam but listed in learning goals, 3) tasks not listed in learning goals, 4) learning goals not related to tasks, 5) learning goals listed in a few tasks, and 6) tasks related to several learning goals. The results showed that most of them correspond to the 5th classification, followed by the 3rd and 4th categories, which are mostly basic science learning goals. Tasks without learning goals are not included in the curriculum; thus, the curriculum needs to be supplemented. The overlapping learning goals of several subjects for one job skill must be reduced in job-oriented education. Conclusion: We suggest that the dental hygiene curriculum be developed based on task analysis and reflected in the national dental hygienist exam. The clinical practice performance of dental hygienists will take further leap forward through task-oriented education.

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.

The purpose of this study was to investigate current QR technology usages and merchandisers' roles and information activities in the Korean apparel industry. Data were collected by interview and questionnaire with merchandisers in apparel companies, manufacturing apparels for both men and women. Statistical analyses were t-test, ANOVA, frequency with SAS program. The results of the study were as follows: 1. The usage of QR technology was generally low. But POS, bar-coding, logistics and small lot order were highly used compared to other technologies. CAD, automated sewing operation, unit product system, logistics, and small lot order were more used in domestic national brand than in import license brand. POS applications were more used in product planning division than in others. 2. Merchandisers played important roles in making major decisions on cost price, sales price, manufacturing request, delivery data, production quantity, produce mix, budget planning, market timing and delivery channels. Products planning was conducted mostly on a monthly basis. Price was determined mainly according to cost price, while the production quantity depended on the last year's sales. Usually sales were analyzed on a daily basis. 3. Merchandisers got more information on fashion them and color trend from foreign information sources than from domestic, while more information on fabrication from domestic sources. For fashion design information they used the equal amount from domestic and foreign sources. Over all degree of utilization in each field of fashion information was fugured rather high.

This paper describes the design for radiation pattern directivity of vehicle license plate RFID tag antenna to improve the readable range. Directivity pattern of the proposed passive antenna is decided by the meander line position and the bumper size attached to the tag antenna. In order to prove the verification of the calculated directivity pattern and readable range of the proposed antenna, the tag antenna has been fabricated and measured at the anechoic chamber. It is shown that the maximum directivity gain of the measured radiation pattern of active and passive tag antenna were observed 2.32 dBi and 3.1 dBi, respectively. The maximum readable range of passive tag antenna was measured about 8.5 m at ${\pm}45^{\circ}$ beam direction on the basis of the driving car direction($0^{\circ}$ of azimuth angle).

The concept of license sales and its business model, which was introduced by Dolby 40 years ago, was implemented by Intel in the form of their promotional strategy "Intel Inside" and became the basis for Sharp's Plasmacluster. This strategy proved to be useful in securing stable profitability and competitiveness in the market, as it is designed to (i) license technology, which is an intangible asset, and (ii) combine various communication activities and management strategies to create a brand for the licensed technology. Although the concept and theory of "Technology Brand Marketing" are not fully understood, we know that they exist and are fully functional. Many corporations have branded their technology, though their intention may not be as clear as that of Dolby or Intel. This paper introduces the technology brands of advanced Japanese corporations in different sectors that have striven to earn credibility through "Technology Brand Marketing" and the possibilities this has opened up for them.

The weight of elderly people in Korea has been increasing. Statistics show that the percentage of the elderly people in Korea was 3.1% in 1970; 3.8% in 1980; 5.1% in 1990, and 7.2% in 2000. Based on this trend, thus, the number of elderly people could be estimated to be 14% of the whole Korean population in 2018. This reveals that Korea is entering a super-aging society with remarkable fast pace. In such a change, the statistics related to elderly people driving license and the occurrence of traffic accidents are showing a noticeable numerical value. The number of traffic accident fatality in Korea ranks the highest value in OECD Countries. However, the research on old drivers in the nation is going on partially centering on system improvement and management scheme. Thus, first of all, researches about the linkage & characteristics between the driving behavior of old drivers and traffic accident should be implemented, in order properly to draw system improvement and management scheme for the old drivers. Therefore, the focus of this study is the influence model for discerning the severity of the age-old-caused traffic accidents by inquiring into the relation between the Driving Aptitude Test items that make it possible to measure their behavioral characteristics and influential factors by age group on the basis of the data on traffic accidents. The analysis results can be used as basic data for suggesting the behavioral research and countermeasure for traffic safety and its management for old driver in preparation for the aging society.
