    "abstract": "We emphasize that the composite structure of the nucleon may play quite an\nimportant role in nuclear physics. It is shown that the momentum-dependent\nrepulsive force of second order in the scalar field, which plays an important\nrole in Dirac phenomenology, can be found in the quark-meson coupling (QMC)\nmodel, and that the properties of nuclear matter are well described through the\nquark-scalar density in a nucleon and a self-consistency condition for the\nscalar field. The difference between theories of point-like nucleons and\ncomposite ones may be seen in the change of the $\\omega$-meson mass in nuclear\nmatter if the composite nature of the nucleon suppresses contributions from\nnucleon-antinucleon pair creation.",
