  In a joint paper [4] by Otsubo, Terasoma and the first author, we proved that
the special value 3F2(a,b,q;a+b,q;1) of the generalized hypergeometric function
is a linear combination of log of algebraic numbers if the triplet (a,b,q) of
rational numbers satisfies a certain numerical condition. However there remains
a question how to obtain explicit descriptions of the values. In this paper, we
give a method to do this, which is a further development of the technique in
[4].
