We present measurements of time-dependent CP asymmetries in B{sup 0}{yields}{omega}K{sub S}{sup 0}, f{sub 0}(980)K{sub S}{sup 0}, K{sub S}{sup 0}{pi}{sup 0} and K{sup +}K{sup -}K{sub S}{sup 0} decays based on a sample of 535x10{sup 6} BB pairs collected at the {upsilon}(4S) resonance with the Belle detector at the KEKB energy-asymmetric e{sup +}e{sup -} collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.
