최근 몇 년간 차량 번호판 영상을 인식하는 기술은 많은 발전을 이루어 왔다. 정확한 인식을 위한 핵심기술은 차량 번호판 영역의 정확한 추출이다. 기존의 연구들이 수평/수직 에지와 번호판의 기하학적 성질을 이용하였고, 현재는 칼라 성분을 이용하는 방법들이 연구되고 있다. 그러나 에지 정보나 칼라 정보로 번호판을 추출할 경우, 번호판을 보는 시각에 따른 기울어진 번호판의 정확한 영역 추출이 어렵다. 따라서 본 연구에서는 칼라 정보를 이용하여 후보 영역을 추출한후 선형 회귀 방정식을 사용하여 보다 정확하게 차량 번호판 영역을 추출할 수 있었다.

According to some statistics, about 13,000 passenger aircrafts are daily flying over the globe and these aircrafts are struck by a lightning flash at least once a year. But so far we have never heard lightning injured any passengers and crew members got shocked by lightning. The aircraft, lightning and the sky are inseparably related to each other. Accordingly, the aircraft and lightning are also inseparably related to each other. They say lightning is easily attracted to metals and these aircrafts are incidentally made of metal. Aircraft become statically and electrically charged when flying because of the friction with air. A lot of research and investigation to protect aircraft from the influence of lightening have been made since the early days. The following descriptions outline researches and investigations on how aircraft and ships get aways from lightning flashes during the flight or the sail. (Research and Investigation on Aircraft and Ships Get Aways from Lightning Flash)

The role of information system(IS) audit is growing more important according to rapid change of Information technology. This article is to introduce what is IS audit, purpose and effect of IS audit. Now most clients of private IS audit services companies are the public sector. Korean public sectors invest a lot of money to build or implement their information system. Most of their systems are developed by system intergration companies. But they do not have professional engineers to evaluate and review outsourced information system. Therefore they must use outside private professional engineers for sysem auditing. We, including writer, established the first IS audit sevice company in Korea on September in 1997. After that about 15 IS audit service companies are established until now. The effect of IS audit is highly evaluated In public sector by the clients Most clients think IS audit service contributed to upgrade the quality of software and standard the methodology of developing system

해상을 운항하는 선박들은 충돌, 좌초, 침몰, 전복 및 조난 등의 위험에 노출되어 있으므로항행 중에 발생할 수 있는 여러 가지 해양사고의 요인을 살펴보고 방지 대책을 생각해 보았다. 일단 해상에서 사고가 발생할 경우 신속하고 효율적인 구조를 위해 유관기관 사이에 일원화된 지휘체계가 필요하다. 또한 해양사고의예방을 위해서는 선원들에 대한 안전교육을 강화하고 안전한 항행을 위한 항행여건을 개선하는 것이 중요하다.

The government has designated the hydrogen industry as one of the three most innovative industries and is making a lot of investment and support. Chungcheongbuk-do and Chungju are developing strategies to foster local industries in line with these government policies. Hyundai Mobis's Chungju plant, located in Chungju, is the only fuel cell plant in Korea and is emerging as the center of hydrogen cars as the government's hydrogen mobility industry expands. Chungcheongbuk-do and Chungju City seek to attract relevant institutions and companies based on their regional strengths. In this paper, the current status of hydrogen industry in Chungcheongbuk-do and Chungju-si is discussed and future plans are discussed.

SUMMERY 1. The length of trypanosoma can be shown 17-25μ on the korean dairy cattles. 2. Crjthida of trypanosoma was is found out in depresed Tabanid flies head and about 60% in Tabanid flies head. 3. Trypanosoma in the tryptose blood agar base was variated afrer about 6 weeks. 4. Infectional rate of trypanosoma is same tate about 52%. 5. Mild production in multltlic infected dairy cattles is delow thbn non inflected daily cattes. and fat rate is about 3.1% in Holstein. 6. Injected trypanosoma rate in summer is higher than in winter about 10%. 7. Calfs in winter wasnot infected for trypanosoma. 8. Erythrocyte number decrease and Leucocyte number increase in a lot of infected trypanosoma of dairy cattles. 9. There is degeneration is genital organs. endocrine gland.

An efficient and productive R&D operation is a major source of competitive advantage in today's economy, and a lot of efforts are made to raise R&D productivity. A prerequisite for making R&D more efficient and productive is to be able to measure it. Hence, a number of studies have attempted to measure R&D productivity. R&D productivity, in the previous studies, was measured with patents at the firm or industry level. However, most previous studies considered only a quantitative aspect, not a quantitative aspect of patents. In this study, various dimensions of patent quality as well as patent quantity were considered for the measurement of R&D performance. The differences in R&D performance across sectors were examined, and it was found that electrical/electronic industry shows higher R&D performance than mechanic and chemical industries. Discriminant analysis based on inputs and outputs for R&D shows' that there exist a strong discriminatory power across industries. The results of this research can provide the directions 'for the firm's R&D policy.

새로운 마이크로프로세서의 설계, 최적화, 그리고 완성 후 어플리케이션의 작성 단계에서 칩의 명령어 집합 시뮬레이션은 필수적인 요소이다. 그러나, 기존의 시뮬레이션 툴들은 저 수준의 하드웨어 기술언어와 게이트 레벨 이하의 시뮬레이션으로 인해 시뮬레이터 구성과 실행 시에 상당한 시간적 지연을 초래하고 있다. 본 논문에서는 이러한 문제들을 해소하고 칩 제작과정에서 발생하는 잦은 설계 변경에 유연성 있게 대응할 수 있는 레지스터 전송 수준의 명령어 집합 시뮬레이터 생성기를 제안하며 그 설계 및 구현에 관해 기술한다.

Quality services such as the integrated service and the differentiated service have been expected to be supported by public Internet as multimedia applications proliferate. Despite a lot of techniques for quality services have been devised, the prospect for the deployment of these techniques is not clear yet. In this research feasibility of real world quality service is investigated based on former experiments and recent trends in Internet applications. User network-based quality services are considered as the most feasible and economic short-term solution, which are also flexible in nature. Milestones and key technologies for some specific public network-based quality services are also described.

The shipbuilding scheduling has many possible alternatives because of its long time horizon and a lot of jobs, so it is required that the scheduling system can generate and search feasible alternatives rapidly. The scheduling in the assembly shop is initiated by allocating, namely loading, the assembly blocks to each shop. In this step, the resource capacities (such as available man/hour, available crane) of each shop must be considered. The result of loading without above consideration can make the scheduling result based on that infeasible or worse one. In this paper, we developed the optimal scheduling system of shipbuilding, specifically for loading and scheduling of assembly block, using ILOG Solver/Scheduler. ILOG Solver/Scheduler is a general-purposed commercial software which supports to find a feasible or optimal solution using object oriented technique and constraints satisfaction programming, given constraints and objectives. Also, in order to enhance the system performance, we conducted various experiments of ILOG search strategies. The experimental results showed that the impact of search strategies is significant.
