  We study the characteristics of the QCD phase transitions in dense hadronic
matter using the Skyrme model constructed on S^3. We find numerically the
localized solutions on $S^3$ using the extended Skyrme model which implements
correctly the scale symmetry of QCD. The transition from the localized phase to
the delocalized phase is found to be of first order at the critical radius of
the hypersphere, $L_c$. The chiral restoration and the gluon decondensation
also take place at the same critical size.
