The aim of this note is to take another side view of the result of authors. 

The preprint mainly concerns Nielsen-Thurston type of 
a surface-automorphism and its behavior under drilling a surface. 

In this note, as an application, we consider 
the hyperbolicity of a knot appearing as a section 
in a surface bundle over the circle admitting a Seifert fibration. 
Although no Seifert fibered 3-manifold is hyperbolic, 
it is conjectured that 
there exist plenty of such hyperbolic knots. 

We will actually confirm this in some cases by 

describing when such a knot is hyperbolic 
in terms of the projection of a knot.
