On the Bosonization of $L$-Operators for Quantum Affine Algebra   $U_q(sl_2)$
  Some relations between different objects associated with quantum affine algebras are reviewed. It is shown that the Frenkel-Jing bosonization of a new realization of quantum affine algebra $\Uqa$ as well as bosonization of $L$-operators for this algebra can be obtained from Zamolodchikov-Faddeev algebras defined by the quantum $R$-matrix satisfying unitarity and crossing-symmetry conditions.
