Abstract: The present invention relates to a method of forming an anodic oxidation coat having excellent corrosion resistance and insulation properties on the surface of an aluminum or aluminum alloy member, and to an aluminum or aluminum alloy member having an anodic oxidation coat manufactured using the method. More particularly, the present invention relates to a method of forming an anodic oxidation coat having high hardness and excellent corrosion resistance and insulation properties without internal defects in an anodic oxidation coating layer, and to an internal member of a device for manufacturing a semiconductor or a display, the internal member being coated with an anodic oxidation coat manufactured using the method.

Abstract: An apparatus and method for controlling a cloud printing service are provided. The method includes receiving, from a first device, a request to create a shared account, creating the shared account for which at least one authority is set, transmitting, to the first device, information for logging into the created shared account, executing authorization when a request to log into the created shared account is received from a second device, and when the authorization succeeds, providing a cloud printing service to the second device within the at least one authority that is set for the shared account.
