KN interaction in the quark-gluon exchange framework
  The general meson-baryon potential obtained in the context of the Fock-Tani formalism is applied in the $K^{+}N$ system. A simple spin-dependent interaction on quark level is used in order to compare with known results. The short range nature of the equivalent local potential is shown.
