Abstract: A server according to an embodiment includes a processor configured to receive a friend add request for a target account from a user terminal accessed with a user account; based on one of the user account and the target account being a protected account, transmit an approval request for the friend add request to a protector account connected to the protected account; and based on receiving a reply to the approval request from the protector terminal, add the target account to a friend list of the user account.

Abstract: Disclosed is an in-line apparatus system that comprises a plurality of sub-apparatuses, a host, a plurality of apparatus controllers, and a master controller. The sub-apparatuses perform predetermined jobs on the substrates. The host stores information on the substrate to be processed in the sub-apparatuses and information on jobs performed by the sub-apparatuses. The apparatus controllers respectively control substrate jobs in the sub-apparatuses according to the information on the substrates and jobs, and are interconnected through a network and share information on the substrates. The master controller, connected to the apparatus controllers, controls the apparatus controllers and receives job information of the sub-apparatuses from the apparatus controllers and transmits the job information to the host. The in-line apparatus system and its control method enable overall easy control and increase reliability.

Abstract: Disclosed is an automation system and a method for assembling a workpiece. The system includes a first stocker having a plurality of first substrates with a plurality of grades of defects, and a second stocker having a plurality of second substrates to be paired with one of the first substrates, and having a plurality of grades of defects. The second stocker receives the grade of the first substrate and selects the second substrate with a grade corresponding to the grade of the received first substrate. The workpiece is assembled by receiving one of the first substrates and determining the grade of the received first substrate. The grades of the second substrates in a cassette is surveyed and determined if there is a second substrate with the same grade as the received first substrate. One of the second substrates is selected if it is determined that there is a second substrate with a grade corresponding to that of the received first substrate. The selected second substrate is placed in a new cassette.
