**Abstract.**
This paper investigates boundedness properties of
certain classes of functions (which involve partial sums). The
usefulness of the main results not only provide unification of
results of Choi (where each of the results was proved rather
independently), but also generates certain new results.
Applications of our main results are pointed out briefly in the
concluding section.
