In Quark Nuclear Physics (QNP), where hadrons and nuclei are described in terms of quarks and gluons, confinement and chiral symmetry breaking are the most fundamental phenomena. The dual Ginzburg-Landau (DGL) theory, which contains monopole fields as the most essential degrees of freedom and their condensation in the vacuum, is able to describe both phenomena. We discuss also the recovery of the chiral symmetry and the deconfinement phase transition at finite temperature in the DGL theory. As for the connection to QCD, we study the instanton configurations in the abelian gauge a la 't Hooft. We find a good correspondence between instantons and the QCD monopoles. Now it is a matter of time to calculate various quantities within the DGL theory and compare with experiments. We consider the DGL theory be the fundamental theory for QNP as the shell model for Nuclear Physics.
