We observed the OMC-2/3 region in the H13CO+(1-0), CO(1-0), and HCO+(1-0) lines by using the Nobeyama 45 m radio telescope. We identified eighteen dense cores and eight molecular outflows. Five of these outflows were newly found. The linewidths of the H13CO+ cores are twice as large as those of dark cloud cores, and the momentum fluxes (dot{P}flow=Pflow/τD= dot{M}flowVflow) of the outflows are an order of magnitude larger than those of outflows in dark clouds. We found that the mass loss rate of the outflow is proportional to the third power of the core velocity dispersion. This will mean that the outflow rate is proportional to the mass infall rate onto the protostar. By comparing the properties of cores with protostars and those of cores without protostars, we infer that the dissipation of turbulence initiates star formation.
