The significant role of colors in fashion design is not enough to emphasize in terms of one of the important design elements and its influences on the behaviors of the people. The purpose of this research is to examine the traditional Chinese colors and its ways of color combinations to appreciate the Chinese culture and its people. The Chinese traditional costume of Ching Dynasty were investigated through historic records, historic nobles, costume accessories and so on. The results of the study were summarized as follows： (1) The Blue was the most favoured color for clothing among men and women during Ching dynasty and various blues in terms of hue, value and intensities were used. (2) The bright Yellow which had been a symbol of Emperor were prohibited being used among people. Though, the late period of Dynasty, the regulation became not to strict and various shades of yellow families were adapted among People. (3) The Red which had been preferred during Ming Dynasty were constantly favoured for the formal wears of auspicious events such as weddings. (4) Dark color groups were loved for the clothing which were used as a ground colors against the flamboyant patterns revealing strong visual effects through value contrast or primary color combinations. (5) The White had a symbol of mourning and there were some intentions to adopt pale color groups such as mint, jade, gray, moon whit,. silver white to make up for white. (6) Contrast color combinations were one of the basic ways of color combination in Chinese traditional costume. Therefore Chinese color combinations has a strong visual effect and easy to draw attention of people by the contrast of the hue, value or intensity of color. (7) Multi-color combinations were another characteristics of Chinese costume in the formal wears which bears many surface designs. The surface decorated with full of motifs, were appreciated by the people expressing their longings and hopes through the auspicious meanings of patterns and striking visual effects of color combinations.

본 연구에서는 쿼드러춰 방식의 초음파현미경을 구성하고 미세한 높이변화를 갖는 표면결함에 대한 진폭영상과 위상영상을 복원하여 상대적인 영상 강도의 변화와 영상의 질을 비교 분석하였다. 본 실험에서는 중심주파수가 3㎒인 focused 변환기를 사용하여 초음파현미경을 구성하고 알루미늄 재료를 선택하여 하나는 직경이 2㎜이고 깊이가 100㎛인 원형결함을 갖도록 하였고 다른 하나는 직경이 4㎜이고 깊이가 5㎜인 원형결함을 갖도록 시편을 제작하였으며 이들에 대한 진폭과 위상영상을 복원하였다. 결함 깊이가 100㎛인 원형결함이 존재하는 시편에 대한 라인 스캔(line scan) 결과 상대적인 영상강도의 진폭 변동율은 7%로 미약한 반면에 위상 변동율은 89%로 커다란 변화를 나타내므로 결함에 대해서 위상영상이 우수한 콘트라스트를 보였다. 이에 비하여 결함의 깊이가 5㎜인 시편에 대해서 진폭영상은 위상영상에 비하여 우수한 콘트라스트를 보이므로서 결함 깊이가 한 파장을 기준으로하여 위상영상과 진폭영상은 큰 차이를 나타내었다. 따라서 쿼드러춰 검출방식의 초음파현미경은 진폭만을 검출하는 포락선 검출기에 비해 한 파장보다 작은 높이변화를 갖는 결함의 탐상시 위상영상을 진폭영상의 상호보완적인 관계로 사용하므로서 결함의 미세 높이 변동을 효율적으로 평가 할 수 있다.
