  We develop the dynamical core-corona initialization framework as a
phenomenological description of the formation of quark gluon plasma (QGP)
fluids in high-energy nuclear collisions. Using this framework, we investigate
the fraction of the fluidized energy to the total energy and strange hadron
yield ratios as functions of multiplicity and scrutinize the multiplicity
scaling of hadron yield ratios recently reported by the ALICE Collaboration.
Our results strongly indicate that the QGP fluids are partly formed even at the
averaged multiplicity for nonsingle diffractive p+p events.
