This study is to analyze consumer's visiting fashion trade area. The purpose of this study, focused on Taegu fashion area, Dongsungro and Bum udong, consumer's spatical beravior, fashion- life-style, clothing purchasing type and Store- Image, etc. This study targeted 580 women aged from 15 to 25 visiting fashion trade area. The methods of measuring include consumer behavior scale, fashion life style scale, clothing purchasing type scale and Stor - Image scale. In process of statistics, the frequency was used to measure consumer's spatical behavior, MANOVA to measure, fashion life style and $\chi^2$ examination was employed to measure clothing purchasing type. The followings are the conclusions of this study ; 1. consumer's spatical behavior by FTA(fashion trade area) : Most people visiting Dongsungro A trade area and Bum udong trade area depart home, while Dongsungro B trade area from school. In case of Bum udong trade area, in particular, more people move from other trade area than people do in Dongsungro trade area. 2. Consumer spatical behavior means by FTA : Bus is far most common transportation. 3. The purpose of visit by FTA : Most people visit Dongsungro B trade area for shopping, while Bum udong trade area for shopping and as a place for appointment. 4. The visiting frequency by FTA : In case of both Dongsungro A.B trade area and Bum udong trade area, at least once a week is most common. Particularly in case of Bum udong trade area, the number of people visiting once every three months and once more than six months is almost same. 5. A company by FTA : People accompanied by the same sex friends are most common in Both Dongsungro A, B trade area and Bum udong trade area in case of Dongsungro B trade area. There is no case of people accompanied by family. 6. The purpose of purchasing fashion comodities by FTA : In case of Dongsungro A trade area for recreation. In case of Dongsungro B trade area and Bum udong trade area, because of affordable price. 7. A Brand - pursued tendency by FTA : Much higher in Dongsungro trade area than Bum udong trade area, among consumers. A character - pursued tendency by FTA : Higher in Dongsungro A than Dongsungro B,A practical tendency and symphatetic tendency Higher in Dongsungro B than Dongsungro A or Bum udong trade area. 8. A Store - Image scale by FTA : The quality of goods is more important to consumers in Dongsungro B than to consumers in Dongsungro A. The data - service and atmosphere are much more important to consumers in Dongsungro B than to consumers in Dongsungro A and Bum udong trade area. The convenience is more important to consumers in Dongsungro B Bum udong trade area than to consumers in Dongsungro A. 9. There is no significant difference among clothing purchasing types by FTA.

Holographic diffraction gratings which are the core element of the optical instruments such as a spectrophotometer have been fabricated using the photoresist as a recording material. A 488nm line from an argon laser is used in making the gratings. Transmission type surface-relief phase grating and reflection type which is fabsricated by coating the aluminum on the transmission type with thickness 2000\ulcornerare fabricated, the spatical frequency of which are 1200 lines/mm. Diffraction efficiency, scattered light and wave-front aberratin are measured to test the performance of the developed gratings. A marimum diffraction efficiency is given when light is incident at the Bragg angle. Theoretical efficiency is about 80%, but measured efficiency of the transmission type and reflection type is 50% and 45%, respectively.

목적: 20대 성인 남녀의 단안과 양안 대비감도를 공간주파수 3.0, 6.0, 12.0, 18.0 cpd를 이용하여 측정하고 단안과 양안의 차이와 남녀간의 차이 등을 비교해 보고자 하였다. 방법: 안경광학과 재학생 99명(남 51명, 여48명)을 대상으로 Topcon CV-3000 Phoroptor를 이용하여 완전교정 후 명소시(100 $cd/m^2$)상태에서 CSV-1000E(VectorVision, Ohio, USA)를 이용하여 2.5 m 거리에서 대비감도를 측정하였다. 결과: 명소시 2.5 m에서 검사한 전체 표본의 평균 대비감도는 3, 6, 12, 18 cpd에서 각각 우안은 52.54, 80.40, 36.79, 13.56이고, 좌안은 52.33, 81.29, 41.73, 14.22이었다. 또한 양안은 65.46, 113.69, 52.04, 19.44로 측정되었다. 20대 남성의 대비감도는 3, 6, 12, 18 cpd의 공간주파수에서 각각 우안은 58.22, 83.52, 37.89, 13.82이고, 좌안은 56.03, 91.52, 46.68, 15.67이었다. 또한 양안은 70.89, 120.96, 56.56, 19.89로 측정되었다. 20대 여성의 대비감도는 3, 6, 12, 18 cpd의 공간주파수에서 각각 우안은 46.50, 77.09, 35.61, 13.28이고, 좌안은 48.40, 70.43, 36.47, 12.68이었다. 또한 양안은 59.68, 105.97, 47.23, 18.95이었다. 결론: 남녀 모두 단안 보다 양안의 대비감도 값이 높게 나타났다. 대비감도의 남녀 차이는 우안 3 cpd, 좌안 6 cpd, 12 cpd, 양안 3 cpd에서는 통계적으로 차이가 나게 남자가 높았으며, 다른 주파수에서도 통계적 유의성은 없으나 대체로 남자가 높은 것을 알 수 있었다.
