Renormalization constants of vector (2,) and axial-vector (ZA) currents are determined non-perturbatively in quenched QCD for an RG-improved gauge action and a tadpole-improved clover quark action using the Schr6dinger functional method. Meson decay constants f, and fT show much better scaling when

The non-perturbative csw determined by the Schrtidinger functional (SF) method with the RG-improved gauge action in dynamical Nf = 3 QCD shows a finite volume effect when the numerical simulations are carried out at a constant lattice size L/a. We remove the unwanted finite volume effect by keeping
