  High angular resolution far-infrared observations at 143 & 185 \micron, using
the TIFR 1-m balloon borne telescope, are presented for two Galactic star
forming complexes associated with IRAS 00494+5617 and 05327-0457. The latter
map also reveals the cold dust in OMC-3. The HIRES processed IRAS maps at 12,
25, 60 & 100 micron have also been presented for comparison. Both these regions
are illuminated at the edges by high mass stars with substantial UV flux.The
present study is aimed at quantifying the role of the nearby stars vis-a-vis
embedded young stellar objects in the overall heating of these sources. Based
on the FIR observations at 143 & 185 micron carried out simultaneously with
almost identical angular resolution, reliable dust temperature and optical
depth maps have been generated for the brighter regions of these sources.
Radiative transfer modeling in spherical geometry has been carried out to
extract physical parameters of these sources by considering the observational
constraints like : spectral energy distribution, angular size at different
wavelengths, dust temperature distribution etc. It has been concluded that for
both IRAS 00494+5617 and IRAS 05327-0457, the embedded energy sources play the
major role in heating them with finite contribution from the nearby stars. The
best fit model for IRAS 00494+5617 is consistent with a simple two phase
clump-interclump picture with $\sim$ 5% volume filling factor (of clumps) and a
density contrast of $\approx$ 80.
