  We present the latest Next-to-Next-Leading order strong coupling constant,
alpha-s, extracted from Gross-Llewellyn-Smith sum rule. The value of alpha-s
from this measurement, at the mass of Z boson, is
alpha-s^{NNLO}(M_Z**2)=0.114^{+0.009}_{-0.012}. We discuss the previous strange
sea quark measurement from the CCFR experiment and the prospects for
improvements of the measurement in the NuTeV experiment.
