This work aims at investigating the molecular gas component in the vicinityof two young stellar object (YSO) candidates identified at the border of theHII region G034.8-0.7 that is evolving within a molecular cloud shocked by theSNR W44. The purpose is to explore signatures of star forming activity in thiscomplex region. We performed a near and mid infrared study towards the borderof the HII region G034.8-0.7 and observed a 90" X 90" region near 18h 56m 48s,+01d 18' 45" (J2000) using the Atacama Submillimeter Telescope Experiment(ASTE) in the 12CO J=3--2, 13CO J=3--2, HCO+ J=4--3 and CS J=7--6 lines with anangular resolution of 22". Based on the infrared study we propose that thesource 2MASS 18564827+0118471 (IR1 in this work) is a YSO candidate. Wediscovered a bipolar 12CO outflow in the direction of the line of sight and aHCO+ clump towards IR1, confirming that it is a YSO. From the detection of theCS J=7--6 line we infer the presence of high density (>10^7 cm^-3) and warm(>60 K) gas towards IR1, probably belonging to the protostellar envelope wherethe YSO is forming. We investigated the possible genetic connection of IR1 withthe SNR and the HII region. By comparing the dynamical time of the outflows andthe age of the SNR W44, we conclude that the possibility of the SNR hastriggered the formation of IR1 is unlikely. On the other hand, we suggest thatthe expansion of the HII region G034.8-0.7 is responsible for the formation ofIR1 through the "collect and collapse" process.
