PURPOSE To examine the activity profiles of elite male competitors during international Taekwondo competition in relation to fin, feather, and heavy weight categories. METHODS Twelve male Taekwondo competitors equally representing fin, feather, and heavy weight divisions were studied during the 2005 World Taekwondo Championships using a time-motion system developed to analyze the activities a...

we show  that a projective maximal submodule of afinitely generated, regular, extending module is a directsummand. hence, every finitely generated, regular, extendingmodule with projective maximal submodules is semisimple. as aconsequence, we observe that every regular, hereditary, extendingmodule is semisimple. this generalizes and simplifies a result of  dung and   smith. as another consequen...

An examination of recent work on prototype-based architectures for object-oriented programming raises a number of interesting questions, the most obvious being: Are prototype-based object-oriented architectures superior to class-based architectures? Another way of addressing the same issues might be to ask: Are class-based architectures over-centralized, and excessively rigid? This work also ra...

in this paper we prove that each element of any regular baer ring is a sum of two units if no factor ring of r is isomorphic to z_2 and we characterize regular baer rings with unit sum numbers $omega$ and $infty$. then as an application, we discuss the unit sum number of some classes of group rings.
