Fig is a fruit of which the flesh is very sweet, and it is a tree which has been grown for fruit in Korea since long time ago. However, since the flesh of fig tends to be easily softened, commercial cultivation of this fruit began later than that of other fruit trees grown for profit, however, the cultivation and demand of fig tend to be increased steadily due to the development of technology for storage and distribution since the 2000s. In addition, as the domestic dining culture is getting diversified, the dishes cooked by using fig as a food material are introduced through diverse foods including dessert, and it is possible to intake fig in diverse ways, but not through the traditional processed food. Therefore, it is necessary to establish a measure of expanding the consumption of fig as a processed food, and it will be possible to overcome the limitation of short storage period, while securing the competitiveness of the fig industry. In this research, we have studied the history of domestic fig cultivation, current status of it and status of processed foods through related documents and materials, and the characteristics of the consumers who purchase figs. Fig is a traditional fruit, however, we could find out the fact that the consumers tend not to recognize it as a traditional one. Therefore, if we could add fig to various processed foods utilizing its sweet taste, rather than increasing the consumption of fresh fruits, it may increase the consumption of it.

본 연구에서는 II-IV 족 화합물 반도체인 CdS를 이용한 액정광변조 방식의 X-ray 검출 시스템을 제안하였다. 제안 된 시스템은 검출부, 신호처리부, 액정 구동 및 투과량 측정부, 마이크로컨트롤러부, 입출력부로 구성되었으며, 소형화 및 휴대형에 적합하게 제작되었다. 또한, 검출 범위 선택을 통하여 광범위한 조건에서 측정이 가능하도록 구성하였다. 제안된 시스템의 성능을 평가하기 위하여 조사선량 변화에 따른 CdS 센서의 출력 특성을 확인하였으며, 우수한 상관 관계를 확인할 수 있었다. 또한, 인가전압에 따른 액정의 변화를 관찰하여 인가 전압에 따른 광투과율을 측정하였으며, 높은 상관관계와 우수한 재현성을 확인할 수 있었다. 이러한 결과를 통하여 본 연구에서 제안된 액정 광변조 방식의 특징인 우수한 재현성과 노이즈 내성 특성을 확인할 수 있었으며, 본 연구를 통하여 제안된 CdS 셀 기반 광변조 방식 의 휴대형 X선 검출 시스템이 소형, 저가형, 휴대형 시스템으로 적용이 가능할 것으로 판단되었다.
