Query: Phenomenological Applications of $k_T$-Factorization (--Large Direct
  CP-Asymmetry in B-meson Decays--)   We discuss applications of the perturbative QCD approach in the exclusive
non-leptonic two body B-meson decays. We briefly review its ingredients and
some important theoretical issues on the factorization approaches. PQCD results
are compatible with present experimantal data for the charmless B-meson decays.
We predict the possibility of large direct CP asymmetry in $B^0 \to
\pi^{+}\pi^{-}$ $(23\pm7 %)$ and $B^0\to K^{+}\pi^{-}$ $(-17\pm5%)$. We also
investigate the Branching ratios, CP asymmetry and isopsin symmetry breaking in
$B \to (K^*/\rho) \gamma$ decays and look for the possible new physics
contribution via gluino mediation SUSY which can accomodate the large deviation
of $S_{\phi K_s}$ from SM.}
