Abstract: The present disclosure relates to a shelf bracket and a refrigerator having the same. The shelf bracket includes a seating portion on which a shelf is seated, a mounting portion provided at a rear side of the seating portion, and a reinforcing portion integrally extending from the shelf bracket and folded to overlap at least one of the seating portion and the mounting portion, so that the strength of the shelf bracket is reinforced by the reinforcing portion.

Abstract: Disclosed is a stepwise automatic orthodontic system and method using an artificial intelligence technique. The method includes: scanning a dental state of a patient by using an intraoral scanner; allowing a server to determine to which group of grouped data of the database the scanned dental data belong; allowing the server to refer to data of the determined group, move a tooth needing orthodontics gradually, and generate a predictive digital orthodontic dental data set; allowing the server to transmit the orthodontic-processed digital orthodontic dental data set of a patient to a 3D printer, and allowing the 3D printer to generate and output a dental orthodontic model; and generating a clear aligner by vacuum-compressing a transparent synthetic resin plate to the generated dental orthodontic model through a vacuum former.
