  We calculate the full 1-loop corrections to the low energy coupling of bulk
gauge boson in a slice of AdS5 which are induced by generic 5-dimensional
scalar, Dirac fermion, and vector fields with arbitrary Z_2 times Z_2' orbifold
boundary conditions. In supersymmetric limit, our results correctly reproduce
the results obtained by an independent method based on 4-dimensional effective
supergravity. This provides a nontrivial check of our results and assures the
regularization scheme-independence of the results.
