   To understand an energetics on protostars, both molecular outflow and
   X-ray emission should be studied. We propose an ASCA observation of a
   giant molecular cloud, NGC 6334, which contains 3 luminous outflow
   objects. With Nobeyama/CSO CO observations, we found an evidence of
   outflow activity of X-ray emitting protostars discovered with ASCA in
   rho-Ophiuchi molecular cloud. Based on the outflow geometry and
   activities, we expect strong X-ray emission from the outflow sources.
   This region is so extensively observed in infrared and radio waves that
   X-ray detection is valuable for the study of massive protostars in a
   giant molecular cloud. Since Einstein satellite detected X-rays with
   S/N ratio of 4.5, ASCA can easily detect hard X-rays from embedded
   massive protostars.
