Resolutions of Several Puzzles at Intermediate $p_T$ and Recent   Developments in Correlation
  Some of the puzzles on hadron production at intermediate $p_T$ found at RHIC are explained as natural consequences of parton recombination. In that framework for hadronization the correlation among hadrons produced in jets can be calculated. Some new results on both near-side and away-side jet structures are presented.
