Abstract: Appropriately generate or update algorithms for a water circulation management system. In a filter management server having a processor for managing the water circulation management system equipped with various sensors including a treated water sensor and a drainage water sensor, for treating drainage water using one or more filters, the processor acquires, using the various sensors, predetermined information necessary for analysis of each of performance of the filters and status of use by a user of a water utilization unit. The processor generates, by analyzing the predetermined information and based on information from the various sensors, information related to timing of replacement of the one or more filters, and user use information including use status of a water utilization unit by the user and water use information including water pollution degree. The processor executes control to notify the user of the water use information and the user use information.

Abstract: Provided is a rice-derived sweetener in which crystallization is inhibited. A rice-derived sweetener contains: a rice-derived component; glucose; and at least one saccharide selected from the group consisting of panose, maltotriose, and isomaltotriose, the glucose being contained in an amount of not less than 4.0% by mass and less than 47.2% by mass relative to a total mass of the rice-derived sweetener, and the panose, the maltotriose, and the isomaltotriose being contained in a total amount of more than 1.96% by mass and not more than 16.00% by mass relative to the total mass of the rice-derived sweetener.

Abstract: A game system executes lottery processing where at least one lottery candidate is selected from plural lottery candidates; gives value according to the lottery result to a user; displays on a monitor a game screen for performing a lottery; controls a shooting game to be played by the user while the game screen is displayed on the monitor; changes an expectant value as the lottery result according to a game-play state of the shooting game; and settles the change at a predetermined timing of the shooting time. Then, the game system executes the lottery processing based on the expectant value settled.
