Let C be a nonempty closed convex subset of a reflexive Banach space E which admits a weakly sequentially continuous duality mapping from E to E* and {T(t) : t 0} be a nonexpansive sernigroup on C such that F = nro F(T(t) =/ 0, f : C -- C, be a fixed contractive mapping. With some appropriate conditions on {anI and {tn}, two strongly convergent theorem for the following implicit and explicit viscosity iterative schemes {xn} are proved: Xn = anf(xn) + (I - an)T(tn)xn, for n EN, Xn+1 = anf(xn) + (I - an)T(tn)xn, for n E N, and the cluster point of {xn} is the unique solution in F to the following variational inequality: ((I - f) p, j (p - x)) or
