Abstract: A health condition estimation device capable of accurately estimating the health condition of a cow includes: a three-dimensional coordinates acquisition unit which acquires a group of three-dimensional coordinates representing the three-dimensional shape of a cow extracted from a distance image of the cow; a feature amount extraction unit which extracts the feature amount of the cow according to the group of three-dimensional coordinates acquired by the three-dimensional coordinates acquisition unit; and a score calculation unit which calculates a score that indicates the health condition of the cow, according to the feature amount extracted by the feature amount extraction unit. It is preferable: that the feature amount extraction unit extracts the feature amount that indicates the degree of sinking of the rumen, according to a group of three-dimensional coordinates in a rumen area in the group of three-dimensional coordinates acquired by the three-dimensional coordinates acquisition unit, the rumen area being an area on the body surface of the cow proximal to the rumen; and that the score calculation unit calculates the cow rumen fill score according to the feature amount extracted by the feature amount extraction unit and representing the degree of sinking of the rumen.

Abstract: A dual-task performing ability evaluation method includes a dual task step (S201), an analysis step (S401), and an evaluation step (S601). In the dual task step (S201), a subject performs a dual task including a movement task that requires the subject to perform specific movement and an intelligence task that requires the subject to answer a specific problem. Further, at least one of motion and an answer of the subject performing the dual task is detected. In the analysis step (S401), the at least one of the motion and the answer that has been detected is analyzed. In the evaluation step (S601), dual-task performing ability of the subject is evaluated based on a result of the analysis.

Abstract: A personal data distribution management system includes source data management devices, a data distribution management device, and a relay processing device that are separate devices and are connected on a network. The source data management device includes a database that stores personal data on an individual subjected to a measurement with a measuring instrument, and attribute information related to the individual and the measurement, the database storing the personal data and the attribute information as original data associated with real name information on the individual. The data distribution management device fetches original data except for personal data, and creates a data catalog. The relay processing device outputs the data, which is the data except for real name information on individuals and from the database of each source data management device based on the data usage request received from the outside, to a data user terminal. This configuration enables data distribution management that reduces the risk of information leakage of personal data and individual real name information.

Abstract: Cognitive function evaluation system (100) includes motion detector (20), answer detector (30), and evaluator (40). Motion detector (20) generates frames representing three-dimensional coordinates of joints of subject (SJ) who is performing a predetermined task. The predetermined task includes a physical task and a cognitive task that requires subject (SJ) to answer questions on a cognitive examination. Motion detector (20) capture images of subject (SJ) to generate the frames. The frames are a series of frames generated in time order. Answer detector (30) detects answers to questions on the cognitive examination by subject (SJ). Evaluator (40) outputs motion features based on the frames and evaluates a cognitive function of subject (SJ) based on the motion features and the answers by subject (SJ). The motion features represent a feature of a spatial positional relationship and a feature of temporal variations, of the joints of subject (SJ) in the captured images.
