Abstract: A data processing system according to the present disclosure includes an acquisition unit and a production unit. The acquisition unit acquires on-site investigation data related to the space. The production unit changes, with respect to article data of the article to be placed in the space, at least one of a dimension, design, and a function on the basis of the on-site investigation data so as to achieve harmony with the space and produces article processing data for processing the article according to the article data after the change. The on-site investigation data includes space-related data related to the space. The production unit produces the article processing data on the basis of the space-related data.

Abstract: An acidic aqueous composition for semiglossy tin electroplating has a water-soluble tin (II)-containing substance and a surfactant. The surfactant includes a surfactant (A) comprising N,N?,N?-polyoxyethylene-N-alkyl-1,3-diaminopropane. The surfactant (A) the number of carbon atoms of the alkyl group that bonds to N ranges from 14 to 18. The weight-average molecular weight of the surfactant (A) ranges from 300 to 1500.
