If we take account of the 'Architectural Tradition' which aims a construction of better environment, we can see that this tradition has ended historically toward Utopia. It is a continual trend from ancient to contemporary epoch in each transitional periods and especially in Sir. Thomas More & in his Renaissance Era. Utopia is an ideal commonwealth in which inhabitants exist under perfect conditions, ideally perfect places or state of things. Utopia's plans are complete projects of image, its goal is an improvement according to the eras. Its plans are characterized by rigid geometrical pattern as circle and square, which contain generally center·axis·enclosure·boundary·symmetry. Recent architectural circumstances no longer reflect utopian visions. Therefore, the Utopian architecture describes characteristics of the era unlike the continuity of its concept.

조명해석 프로그램을 이용한 광선반의 적정크기 선정 및 채광성능분석에 관한 연구

조일식,김병수,이진숙 대한건축학회 2004 대한건축학회논문집 Vol.20 No.6

The purpose of this paper is to make an optimum guideline of a light shelf suitable for the domestic situation, this study is worked by experiments using a light shelf and analysis of variables(light self length, reflectance, angle of a light shelf and domestic position) using illumination program(Lightscape). The result of this study is summarized as follows. 1) Concerning the presence of a light shelf itself, the ratio of the maximum to the minimum inner illuminance and the proportion of inner daylight decrease 3.5times as much as that, whereas a distribution of inner illuminance is uniformed 2) Concerning the Sky conditions, the a light shelf has little effect on the light in the overcast sky, whereas it has an effect on the light in the partial overcast sky with the over 45.000lux and in the clear sky with the over 75.000lux, Especially, in the partial overcast, a light shelf was in the highest of efficiency. 3) Concerning the degree of angle of the a light shelf, there is no change under 10 degree from the horizon, whereas the uniformity ratio of inner illuminance and the proportion of inner daylight increase respectively 48% and 29% between 20 and 30 degree. The latter condition is proved to be better for an uniformed distribution of inner illuminance and a more effective lighting. 4) Concerning the proportion of reflectance of a light shelf, 10% of increase each ranging from 60% to 90% is proved to have no effect on the increase of light. 5)The inner and outer optimum size of a light shelf is proved to be over 200mm and 600mm respectively, which makes it possible to make a general formula adaptable to all parts of our country.

航空機 運航의 效率化 方法 硏究

崔鎰奎 한국항공대학교 1984 論文集 Vol.22 No.-

The safety and economical efficiency of aricraft operations has been made remarkable in bringing about various improvements. In this paper, the methods of reducing fuel with respect to safety operations is studied in light of weather conditions. NAVAIDs, ground operations and navigations. While it leaves much to be done for the various remedies required, these methods suggested in this paper would surely make it possible to effect the applications for the economical efficiency of aircraft operations.

항공기 소음 감소 장치에 관한 연구 : 경항공기를 중심으로

최일규 한국항공대학교 1992 論文集 Vol.30 No.-

항공 교통량의 급증으로 환경 공해 문제중 소음 공해 문제가 날로 심각해지므로서 중 대형 비행기의 소음 피해에 관하여는 운항 방법등 여러가지로 연구되고 있으며, 왕복 기관용 경비행기는 소음 정도가 중 대형 비행기보다 작지만 운항 횟수의 증가로 소음피해 인식이 확산될것으로 보아 소음 감소 장치를 연구 개발하므로 소음 피해를 줄이는데 도움이 되도록 연구하였다. With a rapid increase in the volume of air traffic noise problems of environmental pollution became more serious from day to day. As the harmful effects on human against heavy/large aircraft noise go severe gradually, nowadays many scholars go deep into the study of flight operations, noise abatement devices, etc. in various fields of activity. The noise levels of light aircraft with a reciprocating engine is lower than that of heavy/large aircraft, but in small/light aircraft the number of flight operations is getting more frequent, that is the duration of noise exposure increases and finally conciousness against the aircraft noise shall be disseminated widely. Therefore the purpose of this study is to research and develop noise abatement divices to attenuate the harmful influence of light aircraft noise.

항공기소음 감소장치에 관한 연구 : 왕복엔진을 장착한 경항공기를 중심으로

최일규,송병흠 한국 항공대학교 항공산업기술연구소 1995 航空宇宙産業技術硏究所 硏究誌 Vol.5 No.-

With the air transfortation demand increased, nowadays the need for light airplanes that have piston engines is growing because those have peculiar merits that are dissimiliar in character of airliner. Small aircraft noise problems near the small airfield will come to the front sooner or later according to the air traffic increment rate. In this paper, to attenuate noise levels for light airplanes, first of all noise abatement devices were installed in the exhaust pipes of a FH-20 airplane actually and the noise abatement values have been measured in PNdB(perceived noise level) based on human consciousness against annoyance. Therefore the purpose of this paper is to analyze and estimate the exhaust noise abatement effects on the light airplane by using the noise abatement devices and finally to develop those devices to be utilized widely.
