The gyroscope is the sensor for detecting the rotation in inertial reference frame and constitute the navigation system together an accelerometer. As the inertial reference equipment for attitude determination and control in the satellite, the mechanical gyroscope has been used but it bring the disturbance for mass unbalance so the disturbance give a bad influence to the observation satellite mission because the mechanical gyroscope has the rotation parts. During the launch. The mechanical gyroscope is weak in vibration, shock and has the defect of narrow operating temperature range so it need the special design in integration. Recently the low orbit observation satellite for seeking the high pointing accuracy of image camera payload accept the FOG(Fiber Optic Gyro) or RLG(Ring Laser Gyro) for the attitude determination and control. The Ring Laser Gyro makes use of the Sanac effect within a resonant ring cavity of a He-Ne laser and has more accuracy than the other gyros. It need the 1000V DC to create the He-Ne plasma in discharge tube. In this paper, the design process of the High Voltage Power Supply for RLG(Ring Laser Gyroscope) is described. The specification for High Voltage Power Supply (HVPS) is proposed. Also, The analysis of flyback converter topology is explained. The Design for the HVPS is composed of the inverter circuit, feedback control circuit, high frequency switching transformer design and voltage doubler circuit.

The reconstruction of surfaces from unorganized point clouds can provide very useful information for construction managers. Although point clouds are generally created using 3D scanners, they can also be generated via the structure-from-motion technique using a sequence of images. Here we report a novel surface reconstruction technique for modeling and quantifying earthworks that can be used for preliminary planning, project updates and estimating of earthwork quantities, as well as embedded planning systems in construction equipment. The application of structure-from-motion techniques in earth works is examined and its advantages and limitations identified. Data from 23 earthwork excavation construction sites were collected and analyzed. 3D surface reconstructions during the construction phase were compared to the original land form. Similar experiments were conducted with piles of earth and the results analyzed to determine appropriate ranges of use for structure-from-motion surface reconstructions in earthwork applications. The technique was found to be most suited to pile of materials with volumes less than 2000 m3. Piles up to 10 m in height and with base areas up to $300m^2$ were also successfully reconstructed. These results should be of interest to contractors seeking to utilize new technology to optimize operational efficiency.

This study, on the American hippies and their fashion, is composed of an examination of the following; the social and cultural circumstances of America in the late 1960's, the charac? teristics of the hippies that appeared in the midst of the foresaid background, how those factors materialized in the hippies' distinctive fashion and how they influenced tahion to come. The hippies were composed of the young generation that revolted against all general conventional values of American society and seceded from it, seeking for the ideas of love and freedom. They expressed their newly defined culture-rock music based on drug culture, psychedelic art, rejection of an established society and ethnic tastes that sprang up from nostalgia concerning nature-by means of their own distinctive fashion. And as a revival of the hippies' fashion, neo-hippie and grunge fashions newly appeared in the F /W season of 1992 and afterwards, adding fresher and more abundant sensibility to the original image and layered look of the hippies. The hippies' fashion has not only played a significant part in modem fashion history but will continue to exert its influence in the 1990's as the hippies generation are presently the center of American culture and leaders of world culture. In conclusion, various sorts of "individ- uality" and "the pleasure in the wearing itself" expressed by the original layering of the hippies' fashion presents new promise in the coming development at fashion.

This paper examines the advertisements for mass-produced women's clothing, which appeared in the 1980s issues of the fashion magazine Wolganmeot. This study explores the communicative aspect of fashion advertisements of the 1980s as a platform for complex and dynamic interactions between fashion brands, female consumers, and the rapidly changing social, cultural, and economic conditions of the period. The research focuses on advertisements in the formal and character casual categories that targeted young, urban, and career-seeking women. Based on the analysis of the visual and textual elements of the advertisements from a pragmatics perspective, this paper concludes that fashion brands sought to highlight an 'intelligent', 'urban', and 'individualistic' image of women. It also proposes that the prevalence of assertive and straightforward textual elements, copies, indicates the efforts of fashion brands to stabilize and reinforce the advertising messages in the fast-evolving landscapes of the fashion industry and changing consumption habits.

현재의 객체 추적과 검색의 과정을 보면 고정된 단일 카메라를 통해 입력받은 영상에서 객체를 추출하여 추적하고, 추적된 객체의 구체적인 정보를 알기 위해 줌(Zoom) 기능으로 객체를 인식하는 과정이었다. 본 논문은 다중카메라를 이용하여 객체를 추적하고, 인식하는 것으로써 추적된 객체에 대해 검색인식가능한 영역에 대한 정보를 증강현실로 나타내는 시스템을 제안한다. 제안 시스템의 실험결과를 보면 연산에 포함된 픽셀 수가 현저히 줄어들고, 객체의 인식률이 향상되고, 정보 확인 시간도 단축되었다. 그리고 기존 방법과 비교하여 객체의 움직임을 검출하는 정확성은 물론 움직임 검출에 소요되는 시간도 단축되어 개선된 성능을 보였다.

With 34 years of accumulated operating experience, Seoul Metro has launched a project aimed at exporting second-hand trains(used EMU cars) to Vietnam while seeking measures for diversifying its business such as the construction of the metropolitan railways both at home and abroad, and operating business as a way of fiscal consolidation and management improvement. Therefore, Seoul Metro has moved ahead with this plan considering that there's no legal constraints on durable period of rolling stocks in advanced countries where the vehicles have been used for 35 years or longer than 40 years through renovation such as safety inspection and comprehensive maintenance program, and the railway systems for the replacement are expected to reach 838 cars by 2015 with growth of 100 cars a year. Seoul Metro strives to create value for boosting revenues and recycling resources by sending used EMUs to Vietnam. Seoul Metro will also provide under-developed countries with cars at a low price as well as share the accumulated railway technical know-how so that it can promote the national image and obtain the pre-emptive effect of metro railways in Vietnam.
