Does anyone have code of Lee and Song 2009?

**Dear everyone **
I am very new Dynare user. I am doing my graduated thesis and following the paper “NATURE OF OIL PRICE SHOCKS AND MONETARY POLICY” Junhee Lee and Joonhyuk Song 2009. But I do not understand how to define stead state model and monetary policy simulation on Dynare.

Does anyone have code of this paper? or other work’s code that have the same concept

Best regards,
