Stellar population and star formation histories of distant Galactic H II
  regions NGC 2282 and Sh2-149 complex
  We present here the recent results on two distant Galactic H II regions,
namely NGC~2282 and Sh2-149, obtained with multiwavelength observations. Our
optical spectroscopic analysis of the bright sources have been used to identify
the massive members, and to derive the fundamental parameters such as age and
distance of these regions. Using IR colour-colour criteria and
H$_\alpha$-emission properties, we have identified and classified the candidate
young stellar objects (YSOs) in these regions. The $^{12}$CO(1-0) continuum
maps along with the {\it K}-band extinction maps, and spatial distribution of
YSOs are used to investigate the structure and morphology of the molecular
cloud associated with these H II regions. Overall analysis of these regions
suggests that the star formation occurs at the locations of the denser gas, and
we also find possible evidence of the induced star formation due to the
feedback from massive stars to its surrounding molecular medium.
