We explore properties of stellar kinematics and ionized gas in a sample of
1106 local [U]LIRGs from the AKARI telescope. We combine data from $Wide-field\

\solarm~yr^{-1}$). Our results suggest that starbursts are insufficient to
produce such powerful outflows. We explore the correlations of SFR and specific
SFR (sSFR) with ionized gas outflows. We find that AGN hosts with the highest
SFRs exhibit a negative correlation between outflow velocity and sSFR.
Therefore, in AGNs containing large amounts of gas, the negative feedback
scenario might be suggested.Comment: 20 pages, 14 figures, accepted for publication in Ap
