Claimant's subsequent application for reconsideration and/or full Board review was denied, and these appeals ensued. Inasmuch as claimant did not raise any arguments in his brief regarding the Board's denial of his application for reconsideration and/or full Board review, we deem his appeal from that decision to be abandoned (see Matter of Krietsch v. Northport–East Northport UFSD, 116 A.D.3d 1255, 1256 n. 2, 984 N.Y.S.2d 452 [2014] ). We affirm.
