  The generation and evolution of dust in galaxies are important tracers for
star formation, and can characterize the rest-frame ultraviolet to infrared
emission from the galaxies. In particular understanding dust in high-redshift
galaxies are important for observational cosmology, as they would be necessary
to extract information on star formation in the early universe. We update the
public semi-analytical model A-SLOTH (Ancient Stars and Local Observables by
Tracing Halos) to model the evolution of dust, focusing on high-redshift
star-forming galaxies with stellar masses of $\sim 10^8$--$10^{10}M_\odot$
observed by ALMA ($z\approx 7$) and JWST ($z\approx 11$). We find that these
galaxies should qualitatively differ in their star formation properties; while
the samples in ALMA are explained by dust growth in normal star-forming
galaxies, the lack of dust in the samples by JWST requires dust ejection by
radiation pressure due to recent highly efficient star-formation within a few
10 Myr, with order 100 times higher efficiency than normal galaxies calibrated
by A-SLOTH. Depending on where the JWST galaxies locate on the luminosity
function, their bursty star formation histories inferred from our model can
have impacts for rates of star formation, supernova explosion, stellar
feedback, and detectability of dusty, mature galaxies in the very early
universe.
