This research helps you understand the road traffic noise levels by using a noise map. We have observed the change of the road traffic noise levels around $07:00{\sim}08:30\;and\;22:00{\sim}23:00$ using the noise map in the city. The road traffic noise level is very high both at noon and at night around a beltway and an interchange that is linked with a highway. It seems that the main route of so many vehicles, which are at neighboring cities such as N city and D and H districts and which avoid traffic jams in the city, is the beltway and interchange. The road traffic noise level of a nearby express bus terminal, railroad station, and airport is more than 75 dB at noon and 65 dB at night. The road traffic noise level of G city at night is observed to be more than 55 dB. The noise levels of a residence area and a university are higher than a road with high noise levels when the commuters drive to work. The end of the day exceeds 11 o'clock because of a culture level of development that arouses spare time, eating out, adults' drinking culture, nightlife of the youth, etc. Therefore, the road traffic noise level is high during late night hours, and it exceeds regulatory guidelines(55 dB(A)). It also damages the residence area that is located near the road.

This research is about the changes in the images of Bond and Bond Girl in '007' Series. And it examined through the social background of England from 1960s to 2000s and the costume in the film. The results were as follows: As the era of young fashion was opened after 1960, there was a big change, but Bond was expressed as a hero who had strong male chauvinism of the English aristocratic circles. However, after 1990s, he wore comfortable clothes and he underwent all sorts of hardships. On the other hand, Bond Girl had the image of a sexual target. However, after 1990s, she had sharp appearance and smart brain. Besides, she had professional ideas of a given work and she was changed into a healthy image. Second, Bond's job was an English secrete agent, but Bond Girl had no particular job in 1960s. In 1980s, various professional jobs appeared and in 1990s and 2000s, the professional job which was directly related with Bond's duties appeared. Third, Bond's upper class image was expressed by tuxedo, suit, black, gray, navy, beige, brown, and ivory. His hair was 2:8 parting or Dandy all black style produced his dignified and neat image. After 1990s, he often had casual dress, which created a comfortable image. Bond Girl was expressed feminine style by bikini, underwear, long dress, sky-blue, violet, black, simple costume. After 1990s, she wore a suite, one-piece, or a combat uniform, which showed her professionalism. especially Bond Girl's red dress was used as a psychological color to express temptation, enemy, and betray.

With automobiles sharply increasing worldwide, we are faced with serious social problems such as traffic accidents, traffic jams, environmental pollution, and economic inefficiency. In response, research on ITS is promoted mainly by regions with advanced automotive industry such as the US, Europe, and Japan. While Korea is working to get ahead to take global market through developing and turning into global standards systems related to ASV(Advanced Safety Vehicle), the country is not excellently prepared for such projects. The purpose of ACC is to control the vehicle's longitudinal speed and distance and minimize driver workload. Such a system should be useful in preventing accidents, as it reduces driver workload in the 21st-century world of telematics created by the development of automobile culture industry. In this light, the thesis presents a method to test and evaluate ACC system and a mathematical method to assess distance. Furthermore, for the proposed test and evaluation, theoretical values are tested with vehicle test and a database is acquired, by using vehicles equipped with an ACC system. We proposed the scenarios suitable for the domestic environment and conducted the actual road test. Theoretical evaluation criteria for developing ACC system may be employed and scenario-specific evaluation methods may find their useful application through testing the formula proposed by comparing the database and the mathematical method. and, many companies are expected to utilize the scenario in the developing stage of ACC, and be able to employ as a verification method by harnessing theoretical formula before a road test.

교통사고 예방과 교통난 완화를 목적으로 도입된 지능형교통체계(ITS; Intelligent Transport System)는 민간영역의 다양한 서비스들과 결합하여 새로운 생활양식을 창출하는 종합 서비스의 개념으로 발전하고 있다. ITS 서비스에 이용되는 여행자단말장치도 별도의 장치라기 보다는 기존의 이동전화기, PDA, PC, KIOSK 등을 통해 구현되고 있으므로, 이러한 단말장치들이 갖춰야 할 ITS적인 요소들을 검토할 필요가 있다. 이에 본 연구는 민간사업자들이 ITS서비스를 고려하여 단말장치를 개발할 수 있도록 국가 ITS아키텍쳐를 근간으로 여행자장치형 구성요소를 구현하기 위한 구축단위들의 프레임워크를 UML로 모델링하였다. 모델링과정은 소속서브시스템파악 구축단위/기능명세 일반화, 정보/기능관점 참조모델작성, 참조모델의 UML모델링 등의 4단계를 따른다.

This study is to suggest some developmental policies by analyzing the activities of first aid party in Kwangju and Chonnam regions for two years from Jan. 1, 1991 to the end of December, 1995. First, the residents in Kwangju and Chonnam regions have the sufficient benefits of emergency medical center, but it will be desirable that general hospital should be established and managed in Kohung peninsula which forms the wide island area far away from big cities. Second, the classification of the degree of severe case in the field by rescue members should be strengthened as the means which can reduce the number of patients transferred to the emergency room and the legal method which rescue members can select the medical agency. Third, children less than 10 are most frequent emergent patients and it is due to parent's indifference and children's in sensibility to safety. So the safely education in the course of infant and elementary education should be strengthened and the method which can keep the self safety through the legal system. Fourth, to increase the rate of emergency measure by rescue members, the reasons of fail of emergency treatment are suggested, the treatment results of each rescue member are analyzed every year and it is desirable that the system which can evaluate the personal ability should be introduced. Fifth, the medical accidents occurred in the case of medical act, by rescue members must lake the legal responsibility, but such a problem can he solved with the compensation of insurance system by government. Sixth, to reduce the time required for transfer, traveling service system for the fixed period in beach should be complemented and extended more and service system at ordinary times should be examined at mountains, the area of traffic jams and large special industrial park. Seventh, since service system with one team of two members of 119 rescue party in expressway cannot be mobilized when multiple accidents occur at the same time, it is considered that service system of two teams of four members should be extended. Eighth, first-aid service in expressway is conducted with rescue and emergency treatment by the rescue party at the same time, but the professional rescue lacks and it may result in the injury of patients. Therefore the creation of rescue party in expressway is the urgent problem.

Increasing urban sprawl and climate changes have been causing unexpected high-intensity rainfall events. Thus there are needs to enhance conventional disaster management system for comprehensive actions to secure safety. Therefore long-term and comprehensive flood management plans need to be well established. Recently torrential snowfall are occurring frequently, causing have snow traffic jams on the road. To secure safety and on-time operation of the Bi-modal tram system, well-structured disaster management system capable of analyzing the urban flash flooding and snow pack melt/freezing due to unexpected rainfall event and snowfall are needed. To secure safety of the Bi-modal tram system due to torrential snowfall, the snow melt simulation capability was investigated. The snow accumulation and snow melt were measured to validate the SWMM snow melt component. It showed that there was a good agreement between measured snow melt data and the simulated ones. Therefore, the Bi-modal tram disaster management system will be able to predict snow melt reasonably well to secure safety of the Bi-modal tram system during the winter. The Bi-modal tram disaster management system can be used to identify top priority area for snow removal within the tram route in case of torrential snowfall to secure on-time operation of the tram. Also it can be used for detour route in the tram networks based on the disaster management system predicted data.

최근 지능형 교통관제 시스템에 관한 다양한 연구가 진행되고 있는 가운데 번호판 검출과 인식 알고리즘은 가장 중요한 요소 중에 하나로 대두되고 있다. 번호판은 차량의 고유 식별값을 가지고 있기 때문이다. 기존의 차량 통행 관제 시스템은 정차를 기반으로 하고 있으며 차량의 입출입 인식 방법으로 루프 코일을 사용하고 있다. 이러한 방법은 교통 정체를 유발하고 유지보수 비용이 상승하는 단점을 가지고 있다. 본 논문에서는 이러한 문제점을 해결하기 위해서 차량의 입출입 인식 방법으로 카메라 영상을 사용한다. 차량 통행 관제 시스템의 특성상 카메라가 고정되어 있다. 이에 차량이 접근하면 카메라의 배경화면이 달라진다. 이 특징을 이용하여 배경화면의 차분영상을 구하면 차량의 입출입을 인식할 수 있다. 입출입 인식 후 한국 번호판의 형태학적 특성을 이용하여 후보 이미지를 추정한다. 그리고 선형 SVM(Support Vector Machine)을 이용해서 최종 번호판을 검출한다. 검출한 번호판의 글자와 숫자 인식 방법으로는 CNN(Convolutional Neural Network) 알고리즘을 사용한다. 제안한 알고리즘은 기존의 시스템과 달리 검출 위치를 기준으로 글자와 숫자를 인식하기 때문에 번호판의 규격이 변해도 인식할 수 있다. 실험한 결과 기존의 번호판 인식 알고리즘들 보다 제안한 알고리즘이 더 높은 인식률을 가진다.
