Abstract: A method for producing a resin sintered body 1 by applying an ink 3 to thermoplastic resin powder 2 and sintering the powder, the method including the step of immersing an intermediate resin sintered body 1m, which has an unevenly colored region on the surface thereof and the whole of which has been already sintered, in a surface treatment liquid containing sulfuric acid and chromic anhydride, in which the concentration of chromic anhydride is 300 g/L or more, for 5 minutes or longer. When producing a resin sintered body by sintering thermoplastic resin powder, the surface of the resin sintered body can be evenly and sufficiently colored to an extent required without an unevenly colored region on the surface thereof, and also the surface of the resin sintered body can have a good appearance and smoothness.

Abstract: In an exercise motion analysis system, an input unit inputs motion data corresponding to multiple types of motion parameters indicating motion states of a user who is running. A selection unit selects, from among multiple types of wearing tools, a type of a wearing tool commensurate with a runner type in which motion data of the user is classified, among multiple runner types classified in advance based on cluster analysis on motion data of multiple people. An output unit outputs the type of a wearing tool selected as a wearing tool of which wearing is to be recommended to the user.

Abstract: In a data estimation device, a learning unit creates, using training data including an explanatory variable and an objective variable, a machine learning model that estimates an objective variable from an explanatory variable. The learning unit creates a machine learning model Mi that estimates an objective variable Oi from an explanatory variable group Ei including one or more explanatory variables, sets a new explanatory variable group Ei+1 by adding the objective variable Oi estimated by the machine learning model Mi to the explanatory variable group Ei, and creates a machine learning model Mi+1 that estimates an objective variable Oi+1 from the explanatory variable group Ei+1 (where i=1). The learning unit repeatedly creates a machine learning model while i is in a range of from 2 to (n?1) (n is a natural number greater than or equal to 2).

The twist allowance part 22 is provided in a medial part of a midfoot portion in a shoe sole 1 serving as a bottom portion and allows medial twisting of the heel side with respect to the toe side. The medial reinforcement member 21 is disposed on the twist allowance part 22 and restrains upward bending of the heel side in the medial part.

Abstract: A shoe sole includes an outsole having a contact surface, and a midsole arranged over the outsole, contacting with the outsole.

Abstract: A design element index input unit 10 inputs multiple design element indexes obtained by quantifying design in association with multiple portions constituting shoes. A learning unit 40 uses, as teacher data, pairs of multiple design element indexes and an impression index to learn correlations between multiple design element indexes and the impression index, and creates an impression estimation model. By means of a learned impression estimation model, an impression index estimation unit 60 estimates an impression index obtained by quantifying an impression of shoes, based on a set of multiple design element indexes that have been input. An output unit 70 outputs the estimated impression index.
