In a wireless communication system, a user equipment is configured to establish an RRC link with a cell when operating in a first mobility state or a second mobility state of an RRC connected mode. The first ridge protrudes from a boss surface towards a nose, and the second ridge extends continuously from the first ridge to a slope connected to a cutting-edge land of a linear cutting edge. The administration of the mist is reapplied in order to maintain a predetermined antimicrobial tissue density concentration of a uncompounded silver colloid suspended antimicrobial substance for a predetermined time period. Through this, even if an ink ejection failure occurs in any of the outlets, appropriate density correction values can be obtained for a plurality of outlets.
