• We present the numerical analysis to the flavor non-singlet part of the g_1 structure function including all order resummantion of α_s In^2 x term which is expected to give so much stronger effects than the DGLAP evolution equation. We obtained about 100 % enhancement at x 〜 10^<-3> compared with the leading order analysis of the DGLAP eq. in the case of a flat input density. Then, we found out that the source of the large contribution was the resummed coefficient function which was removed in the calculation of J.Blumlein and A.Vogt in order to respect the factorization scheme independence.
