To detect harmful chemical substances in seawater, we fabricated a prototype sensor and evaluated its performance. The prototype sensor consisted of a detector, housing, and driving circuit. We built the detector by printing an Indium-Tin-Oxide (ITO) nanoparticle film on a flexible substrate, and it had two detection parts for simultaneous detection of temperature and HNS concentration. The housing connected the detector and the driving circuit and was made of Teflon material to prevent chemical reactions that may affect sensor performance. The driving circuit supplied electric power, and display measured data using a bridge circuit and an Arduino board. We evaluated the sensor performances such as response (ΔR), the limit of detection (LOD), response time, and errors to confirm the specification. 해수 중 존재하는 유해화학물질 검출을 목적으로 센서 시작품 제작하고 성능을 확인하였다. 센서 시작품은 검지부, 기구부, 구동부로 구성하였다. 센서의 검지부는 ITO (Indium-Tin-Oxide) 금속산화물 나노입자 (metal oxide nanoparticle) 필름을 기판위에 인쇄하여 제작하였고, 온도와 HNS 농도를 동시에 검출할 수 있도록 2개의 검출 부분을 갖도록 설계하였다. 센서의 기구부는 검지부와 구동부를 연결하며, 검출에 영향을 줄 수 있는 화학적 반응을 막기 위해 테프론 재질을 이용하여 제작하였고, 특히 검지부의 착탈이 용이하도록 설계 하였다. 구동부는 브릿지 회로와 아두이노 보드를 이용하여 전원 공급과 데이터 측정 및 디스플레이가 가능하도록 제작하였다. 시작품의 성능에 대해서는 기존의 수질 센서를 참고한 성능 사양을 제시하고, 유기용제를 사용한 검지부와 시작품의 동작을 확인하여 응답 (ΔR), 검출하한 (Limit of Detection), 응답시간 (response time), 오차 (error) 등을 평가하였다. 또한 해수 중 동작 특성을 파악하여 설계 사양이 구현되었는지 확인하였다.

In this study, the effect of the gender-related organizational factors on organizational output was investigated. The present research conducted 1029 workers consisting of 826 employees and 203 central government officials or local officials about the effects of personally experienced discrimination in the workplace, such as gender equality organizational culture, gender equality work practices, information accessibility, job clarity and sexual harassment experience es on job satisfaction and turnover intention. And the effect of gender-related organizational factors such as introduction of family-friendly policies on job satisfaction and turnover intention is also examined. And, the effect of these factors on the work-family conflict(WIF) and family-work conflict(FIW) was conducted and the moderating effects of family-friendly policies is prominent at effect of work-family conflict on organizational output. In sum, the present research suggest that accessibility information, gender equality work practices and family-friendly policies have improved organizational output. And for women, the more work practices is gender equality, the less work-family conflict(WIF) and family-work conflict(FIW) are. However, the relationship between organizational culture and gender equality organizational culture is opposite. Futhermore, for women, the moderating effects of family-friendly policies is prominent at prediction of organizational output by family-work conflict(FIW). In contrast, for men, the moderating effects of family-friendly policies is prominent at prediction of organizational output by work-family conflict(WIF). This research introduced that a family-friendly policies to improve the organizational output is meaningful. The last, the significance and limitations of this study and future research are discussed.
