  The full $\mathcal{O}(\alpha)$ electroweak radiative corrections to $t
\bar{t} \gamma$ and $e^-e^+\gamma$ productions at the International Linear
Collider (ILC) are presented in this paper. The computation is performed with
the help of GRACE-Loop system. In the physical results, we discuss on the cross
section, electroweak corrections, and the top quark forward-backward asymmetry
($A_{FB}$) which are the function of the center-of-mass energy.
