In [13], the authors defined a multifunction F : X - Y to be upper (lower) almost weakly continuous if for each x należy do X and each open set V containing F(x) (resp. F(x) iloczyn V=0) x należy do Int(Cl(F+ (Cl(V)))) (resp, x należy do Int(Cl(F- (Cl(V))))). In this paper, further characterizations and several properties concerning upper (lower) almost weakly continuous multifunctions are obtained.
