Abstract

In this study, a method for estimating the amount of urination for men, was suggested and its performance was evaluated. This study is a preliminary one for the development of a health monitoring system that needs un-constraining, non-intrusive and long-term measurements in daily life. To estimate the amount of urination, a wide weighing plate with load cell was built and the difference in a man's weights between before and after urination was measured while he was standing on the plate. The results showed that the amount of urination can be estimated with the measured weight difference under the condition of mild movements. The largest measurement error of the suggested method was 40g, which means that this method can be applied to health monitoring in daily life. It is expected that the results of this study will be the basis for developing practical un-constraining and non-intrusive health monitoring system for daily use at home.

본 논문에서는 일상생활에서 무구속, 무간섭으로 장기간의 건강 모니터링의 기술 개발의 기초 연구로서 남성의 배뇨 중의 체중 변화를 측정하여 배뇨량을 추정하는 방법에 대한 성능 평가를 수행하였다. 배뇨 중의 체중 변화 측정은 로드셀 (load cell)을 이용하여 넓은 체중 측정판을 만들고, 이 판을 소변기 또는 좌변기의 앞에 놓았다. 남성이 체중 측정판 위에 올라가 서서 배뇨를 하는 동안, 남성의 체중을 연속적으로 측정하였다. 배뇨 전과 배뇨 후의 체중의 변화를 계산하여 그 체중 변화 즉 감소량으로 배뇨한 소변량을 추정하였다. 실험 결과는, 배뇨 중에 발을 옮기거나 급격히 몸의 자세를 바꾸지 않는다면 체중의 감소로 소변량을 계산할 수 있음을 보였으며, 최대 약 40g 정도의 오차를 보였는데, 이 결과는 일상생활에서의 건강 모니터링에 적용할 수 있을 것으로 보인다. 이 연구의 결과는 일반 가정에서의 실용적인 무구속 무간섭 건강 모니터링 기술 개발에 기여할 것으로 기대된다.
