By use of the concavity of solution for an associate boundary value problem, existence criteria of positive solutions are given for the Dirichlet BVP (Φ(u′)) ′ + λa(t) f (t,u) = 0, 0 < t < 1, u(0) = 0 = u(1), where Φ is odd and continuous with 0 < l1 ≤ ((Φ(x)−Φ(y))/ (x − y)) ≤ l2, a(t) ≥ 0, and f may change sign and be singular along a curve in [0,1]×R+
