  Recent developments in the density dependence of the MIT bag radius and
parameters in nuclear matter are discussed. Starting from the MIT bag
lagrangian density, the calculations are specialized for symmetric homogeneous
isotropic nuclear matter. A simultaneous description of the density dependence
of MIT bag model is derived from the Quantum Hadrodynamics and an extended
Quark Meson Coupling model. Results are in agreement with those derived from
Scaling Model.
