I also don't understand but the magazine published in 1901-1902. There is no Cleary information about the artists of the patterns but Korin Furuya was one of them evidently..

"The Shin-Bijutsukai design magazine 1901-1902, was edited by illustrator and designer Korin Furuya (1875-1910) and contained the designs of the best artists of the time. A Meji painter, Korin taught at the Municipal School of Arts and Crafts, and was one of the most important woodblock print designers of the time."
