The geometrical description of deformation quantization based on quant
um duality principle makes it possible to introduce deformed Lie-Poiss
on structures - natural analogues of classical Lie bialgebras for the
case when the initial object is a quantized group. Special types of co
ntractions - the so called first order contractions - play the signifi
cant role in the explicit realization of deformed Lie-Poisson structur
e. Such contractions can be naturally applied to the Drinfeld double.
In the case of (u(1) + sl(2))(q) we investigate explicitly the deforme
d structures induced by the first order contractions.
