  From two different modifications of the Gell-Mann-Okubo mass relation for
(1/2)^+ baryons: the first one given by a version of diquark-quark model and
the second one being the optimal mass sum rule obtained by using quantum groups
U_q(su_n) for the role of hadronic flavor symmetries, we find direct connection
of the mass parameters of the diquark-quark model of Lichtenberg, Tassie and
Keleman to the (proper value of) q-parameter and then to the Cabibbo angle.
