Abstract: Disclosed are a drug evaluation method and apparatus. The drug evaluation method includes acquiring cell images in response to a drug to be evaluated, loading an image processing-based learning model trained so as to predict molar concentrations, outputting molar concentrations of cells corresponding to the cell images by applying the learning model to the acquired cell images, and calculating a drug evaluation value used to evaluate effects of the drug on the cells based on the molar concentrations of the cells corresponding to the cell images output through the learning model.

Abstract: An optical path control member according to an embodiment comprises: a first substrate; a first electrode provided on the upper portion of the first substrate; a second substrate provided on the first substrate; a second electrode provided on the lower portion of the second substrate; and an optical conversion unit provided between the first electrode and the second electrode, wherein the optical conversion unit comprises partition wall parts and accommodation parts which are alternately arranged. The accommodation parts have a light transmission rate that varies according to the application of a voltage, and the accommodation parts comprise a plurality of unit accommodation cells spaced apart from each other, and comprises a dispersion and light-absorbing particles which are dispersed in the dispersion.
