  Confinement and chiral symmetry breaking are the most fundamental phenomena
in Quark Nuclear Physics, where hadrons and nuclei are described in terms of
quarks and gluons. The dual Ginzburg-Landau (DGL) theory, which contains
monopole fields as the most essential degrees of freedom and their condensation
in the vacuum, is modeled to describe quark confinement in strong connection
with QCD. We then demonstrate that the DGL theory is able to describe the
spontaneous break down of the chiral symmetry.
