Hadron Properties in the Vicinity of $T_c$
  Modifications of hadron masses and some of their basic properties with temperature or nuclear density are considered as one possible signature for the formation of dense hadronic matter in nuclear collisions. We discuss here some basic results on the temperature dependence of hadron properties obtained from calculations of hadron correlation functions, the chiral condensate as well as the equation of state in finite temperature lattice QCD.
