  Time-dependent Hartree--Fock (TDHF) method has been applied to various
low-energy nuclear reactions, such as fusion, fission, and multinucleon
transfer reactions. In this Mini Review, we summarize recent attempts to bridge
a microscopic nuclear reaction theory, TDHF, and a macroscopic aspect of
nuclear reactions through nucleus--nucleus potentials and energy dissipation
from macroscopic degrees of freedom to microscopic ones obtained from TDHF in
various colliding systems from light to heavy mass regions.
