Abstract: The present invention comprises: a learning model storage unit that stores a learning model trained by a neural network having, as an input value, a training image obtained by photographing used wet hand towels stored in a collection box from above, and having, as an output value, the number of used wet hand towels; a reception unit that receives an estimation image obtained by photographing the used wet hand towels stored in the collection box from above on a mobile terminal; an estimation unit that uses the learning model stored in the learning model storage unit and estimates, by means of the neural network, the number of used wet hand towels from the estimation image received by the reception unit; and a transmission unit that transmits an estimation result estimated by the estimation unit to the mobile terminal.

Abstract: The present invention provides a composition for regulating carbohydrate metabolism, the composition containing, as an active ingredient, an agent for controlling the amount of D-amino acid in the living body of a subject. Moreover, the present invention provides a method for assessing carbohydrate metabolism conditions of a subject by monitoring the amount of D-amino acid in the living body of the subject.

Abstract: A method for producing beryllium-copper containing at least Be and Cu, includes holding the beryllium-copper for a predetermined solid solution time in a solid solution temperature range in which the Be is dissolved into the Cu, cooling the beryllium-copper at a cooling speed at which the Be remains dissolved in the Cu, applying plastic strain to a cooled beryllium-copper over multiple times in a processing temperature range in which the Be is not precipitated, and holding the beryllium-copper for a predetermined age hardening time in a precipitation temperature range in which the Be is precipitated.

Abstract: A vehicle driving apparatus includes a rotating electrical machine; a power transmitting gear mechanism; and a case in which the rotating electrical machine and the gear mechanism are housed in series in an axial direction of the rotating electrical machine, wherein a low rigidity region, which is a region of the case having low rigidity located at an outer periphery of the rotating electrical machine, is covered by a silencer supported on a high rigidity region of the case having a higher rigidity than the low rigidity region.
