In low magnetic fields, dissipations in granular V~Ba2Cus07\_6 films near the zero-resistance temperature is described by the flux creep in effective Josephson medium. Our picture for granular Y~Ba2Cu307\_~ is an extention to the one for single crystal Y~BazCu3Or.~ with regard to the dissipations in
