Abstract: Provided is a glass article that improves the film strength of a photocatalyst film while maintaining the photocatalytic function and the reflection suppressing function of the photocatalyst film. The photocatalyst film on the glass sheet is formed to contain, in mass %, 50 to 82% of silicon oxide particles, 8 to 40% of titanium oxide particles, and 7 to 20% of a binder component composed of silicon oxide. The average particle diameter of the silicon oxide particles is set to at least 5 times the average particle diameter of the titanium oxide particles. The photocatalyst film is formed to have a structure such that some of the silicon oxide particles in the film serve as protruding silicon oxide particles that are not in contact with the glass sheet and that have their top portions protruding from the surrounding titanium oxide particles and being exposed on the surface of the film, while some of the titanium oxide particles are interposed between the glass sheet and the protruding silicon oxide particles.

Abstract: The present invention improves abrasion resistance and persistence of anti-fogging properties of an anti-fogging article. The anti-fogging article of the present invention includes an article, a porous film formed on the surface thereof, and a hydrophilic film formed thereon. The porous film contains inorganic fine particles and a binder. The binder covers at least a part of surfaces of the inorganic fine particles and is interposed between the inorganic fine particles. The binder contains a metal oxide as its main component and a hydrophilic organic group other than an alkoxyl group. The hydrophilic film contains a hydrophilic organic polymer.

Abstract: A server displays a co-evaluation request containing an evaluation scheme of a first evaluator on a homepage. A second evaluator browsing the co-evaluation request through a terminal device transmits a proportion of user's own assignment as an answer to the server. The server displays the proportion of assignment of the second evaluator on the homepage. Thereafter, each of the first and second evaluators respectively transmits evaluation results of the co-evaluation to the server. The server displays each evaluation result received on the homepage.

Abstract: A server displays a co-evaluation request containing an evaluation scheme of a first component user on a homepage. A second component user browsing this co-evaluation request through a terminal device transmits a proportion of user's own assignment as an answer to the server. The server displays the proportion of assignment of the second component user on the homepage. Thereafter, each of the first component user and the second component user transmits an evaluation result of the co-evaluation to the server. The server displays each evaluation result received on the homepage. The first and second component users exchange the evaluation results through the homepage, and can share the co-evaluation results on the homepage.
