  In the framework of the semihard ($k_T$ factorization) QCD approach, we
consider the photoproduction of D* mesons associated with two hadron jets and
the D* production in DIS at THERA conditions with the emphasis on the BFKL and
CCFM dynamics of gluon distributions. In the photoproduction of D* mesons the
attention is focused on the variable $x_\gamma$, which is the fraction of the
photon momentum contributed to a pair of jets with largest $p_T$. We show that
our theoretical results are sensitive to the BFKL type dynamics which may be
investigated at THERA energies. We also discuss possible effect of $\J/\psi$
meson spin alignement, which is thought to be a vivid manifestation of gluon
off-shellness.
