Autonomia movement that emerged in Italy in the 1960s from workerist (operaismo) communism gives historical and discursive context to Manfredo Tafuri's famous criticism of ideology. His thesis on the death of architecture was a radical criticism of Keynesian intervention which was a strategy to cope with the Great Depression. For him, this capitalist development had taken away ideological prefiguration from architecture. At least Tafuri's this early intellectual phase was formed in the wake of magazine Contrapiano and Antonio Negri's influence. Tafuri almost entirely adapted Negri's thought on the importance of capitalist innovation that was uncovered by Keynes, Schumpeter, and Manheim and the periodization in modern history. When we read Tafuri's text with this concrete context, we can avoid being plunged into his abstruseness. On the other hand, 1980's Korea cannot understand Tafuri comprehensibly. 1980's situation to struggle to acquire democracy prescribed only one mode of reception of Tafuri's historiography in Korea. Tafuri's so-called pessimist view point could not satisfy student activists. They want to take intellectual means to sustain student movement and to secure political dynamics of protest. But at the same time they have anxiety to understand tafuri's thesis that they consider ad a critical theory for Korean Architecture. Double contexts of Tafuri's criticism of ideology bring to light to historicize both Tafuri's historiography itself and reception of his text in Korea.

An experimental investigation of the natural circulating boiling flow characteristic in three cases of annulus with different outer diameter, and the effect of annular gap size on the burnout behavior is presented. The experimental work was conducted for each case of test section at system pressure of $1kg/cm^2$ and inlet subcooling $0-20^{\circ}C$ in the full range of throttling ratio. As the result, the following facts were found. 1) With the increase of ${\Delta}T_{sub}$, $D_{2}$ and A/A_{o}$, $q_{BO}$ increases on the whole, and with the decrease of ${\Delta}T_{sub}$ and $D_{2}$, hydrodynamic instability is accelerated to happen prematually. 2)With the increase of ${\Delta}T_{sub}$, $D_{2}$ and A/A_{o}$ burnout characteristic shows the high velocitylow quality burnout, and with the decrease, low-velocity-high quality burnout. 3)With the decrease of A/A_{o}$, hyddrodynamic instability is singnificantly restrained and the difference of $q_{BO}$ in each $D_2$ under same condition is gradually reduced, finally converging into $1.9{\times}10^{5}kcal/m^{2}-hr$.

Despite both domestic and overseas markets are depressed due to the global financial crisis - the apparel industry is no exception, the market for the outdoor wears including the hiking ones has been recording a high growth rate, making the outdoor wear a high growth industry. The purpose of this study was to provide some basic data useful to our outdoor businesses to help them respond to consumers' needs in the rapidly growing outdoor markets. For silhouettes, the point was given primarily to the oblique cutting to have it follow the human body curves and thereby, look natural and slim. Another point was given to the color schemes along the cutting lines, so that an effect of optical illusion could be created to make the wears look slim making use of lines and colors. On the other hand, in consideration of the rapidly changing weather conditions during hiking, the details were designed practically by setting appropriate hip lengths, using attachable/detachable hoods as well as applying the Velcro & rubber band-type set-in sleeves for the tail edges. As discussed above, the researcher analyzed the design elements for the outdoor wears and developed some sensuous designs meeting consumers' needs to help our outdoor wear businesses to expand their target base, while awakening them of the importance of the outdoor fashion.

This study is directed toward determining the number and characteristics of psychologically meaningful perceptual dimensions required for assessing the sound Ouaiity with respect to vehicle interior and/or exterior noises. and toward identifying the acoustical or psychoacoustical bases underlying the perception. By nonmetric MDS and clustring analysis of sound quality data sets on our own, of critical importance are two perceptual dimensions for which subjective verdicts can be interpreted as loudness and sharpness. The perceptual dimensions based upon similarity judgments could be accounted for 48% and 24% of the variance. each of which might be a match for the acoustic parameter "A-weighted maximum pressure level"(r= .85) and for the psychoacoustic parameter "sharpness" (r= .65), respectively. On the other hand, the perceptual dimensions based upon preference ratings could explain 66% and 10% of the variance. where the acoustic parameter "A-weighted maximum pressure leve"(r= .92) might be taken to be a best predictor, but sharpness appeared to be less suitable for the description of Preference behavior. Linked to the results, the problems of quantitative modelling of subjective sound quality evaluation and also of implementing corresponding cognitive combination rule for technical and industrial applications, say having "winner-sound qualify" according to preference criteria will be shortly in discussion.

The purpose of this study is to examine actual design cases of decorative detail in the Art Nouveau style from the end of 19th century to the beginning of 20th century, and create designs and fashion works to meet our contemporary fashion trends by means of over-decorative style, a characteristic of decorative detail. The characteristics of decorative detail in the Art Nouveau style can be outlined as follows: First, pleats appear with two major feels of solidity, undulated and curvilinear solidity based on gather(ruffle, frill/ flare and flounce) and regular and linear solidity based on linear pleats or tucks. Second, embroidery appears in various patterns developed with stitch of solid feel as well as a variety of coloration effects. Third, attachments are expressed by means of independent motif(applique, gloss effects(beads, sequins), affluent texture and mobility(fur, feather). Moreover, according to technical characteristics and expressive aspects of pleats, embroidery and attachments, it is found that decoration detail in the era of Art Nouveau is over-decoration style. Indeed, it appears in major expressive aspects such as rhythmical solid type, detailed prominence type, superficial touch type and profound volume type.

허브(hub) BLDC(Brushless Direct Current) 전동기란 아우터로터 타입 고효율 전동기로 다극의 영구자석으로 이루어진 회전자가 바퀴의 구동축이 되는 직접구동용 모터를 말하며, 휠인모터라고도 불린다. 본 연구에서는 허브모터를 구동축으로 갖는 2륜 또는 3륜 구동체를 구동하기 위한 BLDC 허브모터 속도 제어기를 PIC 마이크로 컨트롤러를 이용하여 설계한다. 구동기는 6 개의 독립된 MOSFET 스위칭소자를 사용하여 구성하며, 게이트 구동회로는 직접 설계하여 경제성을 높인다.

본 연구는 병원경영지원회사와 영리의료법인의 도입 정책을 살펴봄으로써 디지털시대의 활성화 정책 방안을 분석, 검토하는데 목적이 있다. 의료산업의 빠른 변화는 날로 치열해져 가고 있다. 그런 흐름 속에서 우리나라 또한 의료산업의 양적 질적 성장을 위해 노력해왔으나, 병원경영지원회사의 활성화(MSO) 및 영리의료법인의 도입 같은 의료산업의 본격적 활성화를 위한 정책적 노력에서는 뒤쳐져 있는 상황이다. 의료산업의 시장경제 논리도입에 대한 부정적 시각도 많은 것이 사실이지만, 그러한 부정적 시각까지 아우를 수 있는 의료산업 활성화 정책 방안 마련이 필요하다.

2005년 4월부터 12월까지 매월 강릉 연곡천 5개 지점에서 어류상을 조사한 결과 총 10과 29종이 출현하였다. 우점종은 Zacco platypus (상대풍부도, 29.0%), 아우점종은 Rhynchocypris steindachneri (12.1%)이었다. 한국고유종은 Rhynchocypris kumgangensis 등 6종이 출현하였으며, 인근 하천에 비해 연곡천에만 서식하는 종으로는 Koreocobitis rotundicaudata와 Luciogobius guttatus 2종이 확인되었다. Ladislabia taczanowskii는 지리 분포상 주목되는 종이었다. 연곡천 어류의 종 다양도는 2.521로 높아 서식 종이 다양하고 안정된 군집구조를 이루고 있다.

본 논문은 latch-up의 가능성을 최소화하는 여러가지 방법 중 공정이나 재질 변겨에 의한 방법이 아닌, mask의 layout 변경에 의한 latch-up 최소화 방법에 대하여 기술하였다. 기존의 공정이나 재질 변경에 의한 방법이 어려운 공정이나 특수 시설 사용을 전제로 하고 있는 반면, mask의 layout 변경에 의한 방법은 기존의 공정을 그대로 사용할 수 있는 장점을 갖고 있다. Layout 변경에 의한 latch-up 최소화 방법 수행을 위하여 substrate의 N+와 S-W접합(substrate-well 접합 )사이의 거리를 a, S-W 접합에서 well의 P+까지의 거리를 b로 하여 a와 b가 다른 6개의 latch-up model과 guard ring 구조를 갖는 3개의 latch-up 모델을 만들어 latch-up관련 변수에 대하여 비교 검토 하였다.
