dc.descriptionWe analysis the sea quark densities, based on the constituent quark model. To perform a direct fit with available experimental data, the parameterized Inverse Mellin technique is used. The calculation is extended to the NLO approximation for the singlet and non-singlet cases in DIS phenomena. We employ the approach of complete RG improvement(CORGI) where one is forced to identify and resum to all-orders RG-predictable ultraviolet logarithm terms which truly build the Q-dependence of QCD observable. The results are compared with the standard approach of perturbative QCD in the ${\bar{MS}}$ scheme with a physical choice of scale. The results in the CORGI approach indicate a better agreement to the data.
