Abstract: The shelf tier management system S acquires size information of a shelf tier and size information of an accommodated item that has been accommodated in the shelf tier, obtains a occupancy rate of the accommodated item in the shelf tier on the basis of at least the size information of the shelf tier and the size information of the accommodated item, and calculates a corrected occupancy rate by correcting the occupancy rate with a correction coefficient according to the accommodated item.

Abstract: An information output device includes a first acquisition unit that acquires request information that is a request of a user, a second acquisition unit that acquires working machine information related to performance of an autonomous working machine and set for each type of the autonomous working machine, and an output unit that outputs recommendation information satisfying the request of the user, based on the request information and each piece of the working machine information. The request information includes information about a working time during which the autonomous working machine works, information about a work region in which the autonomous working machine works, and information about a cost for using the autonomous working machine, and the recommendation information includes information about a model of the autonomous working machine to be recommended to the user for acquisition.

Abstract: In a work management device and a work management method, in the case where the number of autonomous mobile working machines used in performing work has been changed, or in the case where, among a plurality of assigned working regions, a difference that is greater than or equal to a percentage threshold value has occurred in a work completion percentage, which is a ratio of a portion where the work is completed to each of the assigned working regions, resetting of the assigned working regions is carried out.

Abstract: A management device includes an acquisition unit, a correction unit, and a notification unit. The acquisition unit acquires, from each of at least two of autonomous working machines, position information calculated by the autonomous working machine based on satellite signals. Based on the position information of a first autonomous working machine having relatively high positional accuracy, the correction unit corrects the position information of a second autonomous working machine having relatively low positional accuracy. The notification unit notifies the second autonomous working machine of the position information that has been corrected.

Abstract: It is intended to provide a method of measuring an activity, which is a method of measuring an activity of an enzymatic reaction in which a lipid-soluble reaction product is formed by catalyzing an addition reaction of two or more kinds of substrates, characterized by comprising a labeling step in which any one of the substrates is labeled, a reaction step in which an enzymatic reaction is carried out in the presence of an enzyme, all substrates and an acceptor, and a detection step in which the reaction product is detected by bringing the labeled molecule and a molecule to be detected close to each other via the acceptor and transferring an energy generated by the labeled molecule to the molecule to be detected, and a method of evaluating a compound utilizing the method of measuring an activity.
