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: A metal fiber media exhibiting superior durability, mechanical strength, and heat transfer efficiency, a filter for an exhaust gas purifier using the same as a filter member, and a method for manufacturing the filter are disclosed. The metal filter media includes a metal fiber mat made of longitudinally-aligned metal fiber yarns each including a bundle of 20 to 500 uniformly-oriented metal fibers and having a length of 0.45 to 0.6 m per 1 g, and a torsion of 1 to 9 turns/m such that the metal fiber mat has a porosity of 30 to 95%, and supports respectively attached to upper and lower surfaces of the metal fiber mat, the supports having a porosity of 5 to 95%. Since the metal fiber media exhibits excellent durability and mechanical strength, no crack is generated in the metal fiber medial due to external impact. Accordingly, there is no possibility of damage. Since the metal fiber media has excellent heat transfer efficiency, uniform heat transfer is achieved during regeneration of the filter.
