A new formulation is presented to treat thermal and quantum fluctuations around the kaon condensate on the basis of chiral symmetry; separating the zero-mode from the beginning and using the path-integral method, we can formulate the inclusion of fluctuations in a transparent way. Nucleons as well as kaons are treated in a self-consistent way to the one-loop order. The effects of the Goldstone mode, stemming from the breakdown of V- spin symmetry in the condensed phase, are figured out. A procedure is discussed to renormalize the divergent integrals properly up to the one-loop order. Consequently the thermodynamic potential is derived. It is pointed out that the zero-point fluctuation by nucleons gives a sizable effect, different from the kaonic one.
