  We show that the quantum affine algebra U_{q}(A_{1}^{(1)}) and the quantum
affine superalgebra U_{q}(C(2)^{(2)}) admit unified description. The difference
between them consists in the phase factor which is equal to 1 for
U_{q}(A_{1}^{(1)}) and is equal to -1 for U_{q}(C(2)^{(2)}). We present such a
description for the construction of Cartan-Weyl generators and their
commutation relations, as well for the universal R-matrices.
