Color diagonal and color anti-symmetric ghost propagator of zero temperature and finite temperature configurations of the MILC collaboration are measured after Landau gauge fixing and the color confinement mechanism and their temperature dependence are discussed.

Temperature dependence of the transverse, electric and magnetic gluon propagator, the screening mass, the A^2 condensate and the ghost condensate are also measured and by comparing the results of quenched configurations and unquenched configurations, effects of quarks on the ghost propagator, which is an essential ingredient of the confinement, is discussed. Comparison of the Landau gauge and the Coulomb gauge QCD is also given. (hep-lat/0612009)
