  We calculate one-loop renormalization factors of generic DeltaS=2 four-quark
operators for domain-wall QCD with the plaquette gauge action and the Iwasaki
gauge action. The renormalization factors are presented in the modified minimal
subtraction (MS-bar) scheme with the naive dimensional regularization. As an
important application we show how to construct the renormalization factors for
the operators contributing to K^0-K^0bar mixing in the supersymmetric models
with the use of our results.
