Disclosed is a cardiopulmonary resuscitation training apparatus. The cardiopulmonary resuscitation training apparatus comprises: a mannequin; a compression plate which is provided towards the chest area of the mannequin and generates a return force; and a display unit which displays the state of the mannequin and shows blood circulation movement in light-emitting lines, in accordance with the pressing of the compression plate. The display unit can be constituted in such a way that the blood circulation movement in the mannequin is displayed by means of LEDs, and the LED movement rate is varied or the LEDs emit light in different colours in accordance with the depth of pressing or the pressing rate of the compression plate. This gives the advantage that the user can implement cardiopulmonary resuscitation close to reality while being made aware of the compression depth and the compression rate.

Disclosed herein is a biodegradable and bioactive glass-ceramic fabricated by mixing a slowly biodegradable glass-ceramic and a highly biodegradable glass-ceramic in a predetermined mixing ratio wherein the bioactivity is maintained to be constant, and the biodegradation rate is controlled by the mixing ratio. The biodegradable and bioactive glass-ceramic is fabricated from a composition consisting of calcium oxide (CaO), silica (SiO), boron oxide (BO), magnesium oxide (MgO), calcium fluoride (CaF) and phosphorus pentoxide (PO).

Disclosed herein are a self-foamed porous ceramic composition and a method for making a porous ceramic using the self-foamed porous ceramic composition. The self-foamed porous ceramic is obtained by fabricating a glass consisting of 41&#x2dc;47 mole % of calcium oxide (CaO), 41&#x2dc;47 mole % of silica (SiO) and 6&#x2dc;18 mole % of borate (BO), pulverizing the glass into a finely-divided glass powder having an average particle size of 1&#x2dc;10 &#x3bc;m, molding the glass powder, and sintering the molded glass powder.
