Abstract: An information processing device includes a processor configured to provide an incentive to a first user who sells or returns a first vehicle in which a part of a first coating film including an easily peelable layer is not peeled off.

Abstract: The toner contains binder resin-containing toner particles and silica fine particle S1, wherein the weight-average particle diameter of the toner is 4.0-15.0 ?m, both inclusive, peaks originating with the silica fine particle S1 are observed in 29 Si-NMR measurement of the silica fine particle S1, and, in the spectrum obtained by 29Si CP/MAS NMR or 29Si DD/MAS NMR, the peak area of a peak corresponding to the D1 unit structure in the silica fine particle S1, the peak area of a peak corresponding to the D2 unit structure in the silica fine particle S1, and the peak area of a peak corresponding to the Q unit structure in the silica fine particle S1 satisfy a prescribed relationship.

Abstract: Oral compositions containing a water-insoluble noncationic bactericide showing improved stability with time and improved rheologic properties, and exerting excellent effects of eliminating dental plaque, preventing halitosis and eliminating tooth-staining substances.Addition of porous calcium carbonate to the oral compositions makes it possible to prevent the decrease in the bactericidal activity of water-insoluble noncationic bactericides such as triclosan and improve the stability thereof while exerting excellent effects of eliminating dental plaque, preventing halitosis and eliminating tooth-staining substances. Furthermore, addition of sodium carboxymethyl cellulose to the oral compositions makes it possible to improve rheologic properties and stability with time.
