Re-formation of Many-Quark Model with the su(4)-Algebraic Structure in   the Schwinger Boson Realization
  The energy eigenstates for the su(4)-algebraic model for many-quark system obtained by the present authors in the Schwinger boson space are reconsidered in the original fermion space. Through this task, the structures of the single-quark and the quark-triplet are clarified. Variations of the su(4)-generators which have been adopted by the present authors are discussed.
