Abstract

Influence of other blond components on measuring glucose concentration was analyzed B)food phantom containing five major components was made. The prediction model was developed based on the measurement of absorption spectra including the first overtone glucose band, i.e.. 1500 ∼ 1850 nm. The concentrations were Predicted using the Partial least squares regression. Factor analysis based on Design of Experiment was Performed to study the influence of other components in predicting glucose concentration. Triglyceride does not influence. Albumin and globulin haute minor effects. However, hemoglobin showed substantial response and the compensation of hemoglobin concentration appears to be required for the model of glucose measurement.

혈액 속의 글루코즈 농도를 측정 시 타 성분이 미치는 영향을 분석하였다. 이를 위하여 헤모글로빈을 포함한 총 5 가지의 주요 성분을 이용하여 혈액 팬텀을 만들었으며 글루코즈의 배음대역을 포함하는 1500 ~ 1850nm의 흡수스펙트럼을 측정하여 농도 추정 모델을 세웠다. 농도 예측은 다변량통계분석 모델인 부분최소자승회귀분석을 이용하였다 다른 성분들이 글루코즈 측정에 있어 미치는 영향은 실험계획법을 적용한 인자 분석에 의하여 조사하였다. 트리 글라이세라이드는 영향을 미치지 않는 것으로 나타났으며. 알부민과 글로불린의 경우 적은 범위의 영향을 주는 것으로 나타났다 하지만 헤모글로빈의 영향은 큰 것으로 나타나 글루코즈 측정에 있어 헤모글로빈의 농도 보상이 필요한 것으로 판명되었다.
