#### Abstract

We are to present some properties of binary relations by means of categorical method. The concept of semi-topogenous structures is due to Cs$\acute{a}$sz$\acute{a}$r. Using this, we give a new definition of a $\sigma$-topogenous structure as a particular type of semi-topogenous structure.
