    "abstract": "At zero-density, meson-nucleon vertex corrections to vacuum polarization are\nstudied in the $\\sigma-\\omega$ model with the cutoff. It is shown that the\nproperties of the vertex corrections to vacuum polarization are somewhat\ndifferent from those described by the ordinary renormalization procedures when\nthe cutoff is small (\u003c 5 GeV). The low-energy effective Lagrangian is\nconstructed in the framework of the renormalization group method. The weak\ntensor and derivative couplings of meson-nucleon interactions may be needed in\nthe low-energy effective theory of mesons and nucleons.",
