Abstract: A cognitive function evaluation device includes: an obtainment unit that obtains utterance data indicating a voice of an evaluatee uttering a sentence as instructed; a calculation unit that calculates, from the utterance data obtained by the obtainment unit, a feature based on the utterance data; an evaluation unit that compares the feature calculated by the calculation unit to reference data indicating a relationship between voice data indicating a voice of a person and a cognitive function of the person to evaluate the cognitive function of the evaluatee; and an output unit that outputs the sentence to be uttered by the evaluatee and outputs a result of evaluation by the evaluation unit.

Abstract: A biosensor chip is placed in a biosensor device and is rotated while a biochemical analysis specimen is measured, the biosensor chip comprising a main body, a holding chamber, a dispensing chamber, a plurality of quantification chambers, and a plurality of measurement chambers. The main body has an inlet into which the specimen is poured. The holding chamber holds the poured specimen inside the main body. The dispensing chamber is connected to the holding chamber via a first channel and dispenses the specimen. The quantification chambers are connected to the dispensing chamber, hold a specific amount of the dispensed specimen, and are disposed at positions located away from a rotational center of a rotary motion according to a distance from the first channel. The measurement chambers are connected to the quantification chambers via a second channel and react the specimen with a biochemical analysis reagent.
