    Let \(R\) be an artinian ring with a primitive idempotent \(e\). Let \(A\leq eR\) and \(M'\leq eR/A\). The author considers the condition: if \(eR/A\) is \(N\)-projective then \(M'\) is almost \(N\)-projective where i): \(N\) is local and ii): \(N\) is a direct sum of local modules, respectively. He also studies QF, QF-2 and QF-3 rings with the above condition. Finally, he studies right almost hereditary rings with \(J(R)^2=0\).
