The effect of gauge fields representing the fluctuations of the local constraint and those of the phases of the bond order parameters is examined for the uniform RVB state, which is a mean-field (MF) solution of the t-J model within the slave-boson formalism. It is found that the crossover temperature for the Bose condensation of holons, T_<BE>, below which the system may be essentially considered to be a Fermi liquid, is considerably reduced as compared with that in the MF approximation. The temperature dependences of the transport relaxation rate and the electrical resistivity are also examined.
