  We study the time and temperature dependent correlation functions for an
impenetrable bose gas with open boundary conditions. We derive the Fredholm
determinant formulae for the correlation functions, by means of the Bethe
Ansatz. In the case of time independent ground state, our Fredholm determinant
formulae degenerate to the one which have been obtained by the help of fermions
