TV 대역 White Space 송수신기에서 스펙트럼 센싱을 위한 RF 에너지 검출기 구조를 제안하였다. 제안된 에너지 검출기는 RF 능동 필터 구조에 기반하며, RF 저잡음 증폭기에 고역통과필터를 포함하는 피드포워드 루프를 추가함으로써 원하는 RF 주파수 성분만 통과시키고 그 외의 대역은 감쇄시키는 동작을 수행한다. 본 연구에서는 기존의 구조가 갖는 단점인 단측파 대역만 억압할 수 있는 문제를 해결하고자 양측파 대역을 동시에 억압할 수 있는 새로운 구조를 제안하였고, 간단한 시스템 모델링을 통해 구성요소의 Non-ideality에 의한 RF 에너지 검출기 성능에 대한 영향을 평가하였다. 또한, 시스템 시뮬레이션을 통해 양측파대역이 효과적으로 감쇄되어 RF 에너지 검출기로서 동작할 수 있음을 보였다.

In contemporary architecture, a tendency of architectural expressions is very various aspects, therefore this study is searched about how to express the works of Richard Meier, the background of his growth, his architectural thoughts and etc. Especially the meanings of 'white architecture' have contained, which was presented on the relationships of nature, light, purity and completeness. Lucid and complex, refined yet robust, rational and poetic, richard Meier's architecture has a timeless quality. for over three decades, he has steered an unwavering course through the shoals and cross currents of architectural fashion, creating a secession of serene white houses museums, public and commercial buildings. from Getty Center, his architectural genius came into the world agaiv. With has architectures, this study tries to read the streams of direction on Richard Meier and contemporary architecture.

불규칙 해상에서 선박의 큰 횡요각의 예측이 중요한 과제로 대두 되고 있다. 본 논문에서는 통계적 해석에 의한 이의 예측 방법을 제시한다. 즉 주어진 비 선형 횡요운동 방정식으로 부터 배의 횡요각과 각속도의 결합 확률 밀도 함수를 구하는 방법을 도입하고 각종 계수들의 값의 변화에 따른 예측 결과를 다른 논문에서 제시한 시뮬레이션 결과와 비교하였다.

This is part of a study on the origin of modernist forms and settings. Forms in Modern Architecture are totally new as though they seemed to be originated from some remote culture. Archaeological studies and Laugier's primitivist attitude to the classical architecture provided a way leading, in the end, to pure structures and abstract forms. An application of the classical elements was combined with the ultimate image of nobility, simplicity and rationality. What the seventeenth and eighteenth century theorists realized in the ruines of the classical structures were not the ones with their original organic vitality but the deteriorated, naked and abstracted ones. The essence of the classical structures has been the one of the main references of the modern white architecture. Ration and Nature were the quintessential terms in the design process of the Enlightenment architects of the late eighteenth and nineteenth centuries as they were in the twentieth century architecture. Pure geometric and symbolic forms were new inventions for the new revolutionary age after the development of architectural Styles, successive until Baroque and Roccoco, ceased to go on to the next phase. Many of their buildings appeared so modem in character, for they were omitted all but the essential structure and decoration. Other sides of rationality in the pre-modern age were evolved in terms of the paradigmatic research and the logic in structure. Durand developed a systematic typological approach to the forms. Geometry was the basis of his designs and his illustrations resembled endless simple geometrical problems. One of the other rational approaches was mainly developed by Viollet-le-Duc. To him, Gothic architecture was the model in which each members functioned actively and exerted counterpressure and the Middle Ages invented new fantastic forms. The several ways of rational approaches in architecture were led to the 'tabula rasa' planning in modern architecture. Nature was remained untouched and not deformed as Ledoux's houses in the $H{\hat{o}}tel$ de $Th{\acute{e}}lusson$ were setted on informal gardens. It is part of the modem image that Nature flows or interpenetrates through the white prisms of the strictest classical purity and machines.

정원을 만드는데 있어서 정원설계가들은 특정한 색을 이용하여 원칙을 정하고 소재를 수집하여 각자의 미의식으로 결합해가는 기법을 사용한다. 본 연구에서는 흰색을 배색의 주조톤으로 하여 유명한 정원인 제킬(Gertrude Jekyll)의 배링턴 코트(Barrington court)와 비타(Vita Sackvill-West)의 시싱허스트(Sissinghurst)의 화이트 가든에 사용된 초화류의 종류와 특성을 통해 설계기법을 연구한다. 사용된 개별식물을 계절, 색, 형태, 초장, 향기로 구분하여 분석하고, 화이트 가든 조성 시 초화류의 미적 결합방식을 제킬과 비타의 작품을 통해 살펴보았다. 제킬은 봄의 신선함을 위한 정원으로 초롱꽃류(Campanula spp.), 백합류(Lilium spp.)를 위주로 식재하였다. 비타(Vita Sackvill-West)는 주로 여름밤의 달빛을 겨냥한 정원으로 델피니움류(Delphinium spp.), 장미류(Rosa spp.)가 대표적인 수종이다. 꽃의 색은 흰색계열로 조성하였으나, 순수한 흰색에서부터 아이보리색과 실버색을 포함하였으며, 꽃의 형태는 흰색의 단일색에서 오는 단조로움을 피하기 위해 강한 형태를 사용하였다. 또한 잎의 색은 흰꽃이 잘 돋보일 수 있도록 연록색, 연회색, 밝은 녹황색 잎을 조합하였다. 전반적으로 차가운 색상 계열을 사용하여 신비감과 시원함, 청정함, 밤에 빛이 반사되었을 때 흰꽃과 더불어 매혹적이고 애상적인 이미지를 추구하였다. 화이트 가든의 조경사적 의의는 색의 잠재력을 발견하고 범위를 제한하지 않는 재식설계기법의 아이디어와 기술로 주제색상을 통한 정원설계의 시발점이 되었으며, 미적 원리에 의한 결합으로 정원예술의 발전에 기여하였다.

The low grade domestic kaoline, such as pink-C and white-D, was converted to metakaoline, which has pozzolanic reactivity by heat treatment in the temperature range of $600^{\circ}C$ to 100$0^{\circ}C$ for preparing the spacer. The spacer was used for supporting the reinforced steel rod during construction to improve the safety of architecture. Pink-C and white-D were completely dehydroxylated when burnt at 80$0^{\circ}C$ for 1 hour and converted to metakaoline. The compressive strengths of specimens added calcined pink-C were lower than those of press molding mortar products inspite of calcining conditions. When white-D with calcined 80$0^{\circ}C$ and 100$0^{\circ}C$ for 1 hour was mixed 30% in the weight ratio of cement, the specimens cured 28 days had 338 $kg/cm^2$ and 347 $kg/cm^2$ of compressive strengths, respectively.

Purpose: The purpose of this study were to analyze ultrasonography on both sides of gastrocnemius medialis of stroke patient. Methods: In fourteen subjects with stroke, the gastrocnemius medialis(GM) muscle were scanned with ultrasonography at the muscle belly at rest at ankle angles of 0 degree (neutral position) and it were measured with ultrasonography on both sides of the leg. Muscle architecture (thickness, pennation angle, fascicle length, density, white area index) was examined using real-time B-mode ultrasonography with 7.5MHz linear-array prob. Results: Thickness of non-paratic side was significantly thicker than paratic side. Pennation angle of non-paratic side was significantly larger than paratic side. Fascicle length of non-para tic side was significantly smaller than paratic side. Density of non-paratic side was significantly smaller than paratic side. White area index of non-paranc side was significantly smaller than paratic side. Conclusion: This study showed that stroke have influenced on mechanical properties and quality properties of skeletal muscle architecture.

Advances in white OLED tandem architecture are discussed.With these structures, stable and low-power full color AMOLED displays can be fabricated that are anticipated to be suitable for large area applications such as TVs. With a tandem architecture, efficient (24 cd/A) OLED structures with exceptional stability (${\sim}100,000\;h$ at $1000\;cd/m^2$) are described. In addition, excellent color gamut (>100% NTSC) can be attained by incorporating advanced color filters into the AMOLED backplane in a typical bottom-emitting configuration.
