  There is a long standing debate about whether or not the annual modulation
signal reported by the DAMA/LIBRA collaboration is induced by Weakly
Interacting Massive Particles~(WIMP) in the galaxy's dark matter halo
scattering from nuclides in their NaI(Tl) crystal target/detector. This is
because regions of WIMP-mass vs. WIMP-nucleon cross-section parameter space
that can accommodate the DAMA/LIBRA-phase1 modulation signal in the context of
the standard WIMP dark matter galactic halo and isospin-conserving~(canonical),
spin-independent~(SI) WIMP-nucleon interactions have been excluded by many of
other dark matter search experiments including COSINE-100, which uses the same
NaI(Tl) target/detector material.
  Moreover, the recently released DAMA/LIBRA-phase2 results are inconsistent
with an interpretation as WIMP-nuclide scattering via the canonical SI
interaction and prefer, instead, isospin-violating or spin-dependent
interactions.
  Dark matter interpretations of the DAMA/LIBRA signal are sensitive to the
NaI(Tl) scintillation efficiency for nuclear recoils, which is characterized by
so-called quenching factors~(QF), and the QF values used in previous studies
differ significantly from recently reported measurements, which may have led to
incorrect interpretations of the DAMA/LIBRA signal. In this article, the
compatibility of the DAMA/LIBRA and COSINE-100 results, in light of the new QF
measurements is examined for different possible types of WIMP-nucleon
interactions. The resulting allowed parameter space regions associated with the
DAMA/LIBRA signal are explicitly compared with 90\% confidence level upper
limits from the initial 59.5~day COSINE-100 exposure. With the newly measured
QF values, the allowed 3$\sigma$ regions from the DAMA/LIBRA data are still
generally excluded by the COSINE-100 data.
