    "abstract": "Relations among the effective hadron masses and the effective interactions in\nnuclear matter are studied by using the generalized relativistic mean field\ntheory. We found that we can make the effective omega-meson mass smaller and\nthe equation of state softer if we require that the omega-meson mean field is\nproportional to the baryon density. In this case, there is a simple and exact\nrelation between the effective omega-meson mass and the effective omega-nucleon\ncoupling. Because of this relation, the effective omega-nucleon coupling\nautomatically decreases if the effective omega-meson mass decreases.\nConsequently, the equation of state becomes softer. A trial to embed the QCD\nsum-rule results into the hadron field theory is also shown.",
