Taking into account the possible parity-nonconservation in the weak interactions, the decay angular distributions of the strange particles produced by the pion-nucleon collisions are re-examined. It is shown that, when the parity-nonconservation effect is actually observed in the decay angular distribution of the hyperon, its spin value can be determined less ambiguously than in the case of the parity-conservation. Especially, in this case, it is possible in principle to decide completely whether the spin is 1 / 2 or not. The effect of the parity-nonconservarion can appear also in the K_<u2>- and K_<π3>-modes of decay, unless the spin of K is zero. Taking this into account, also the possibility of determining the spin value of the K-meson is considered. In this case, however, the conclusion is not so decisive as the case of the hyperon.
