Paper Abstract

The mechanisme of the breathing pump-system changes with age. Morphometrical informations are presented by means of Photogrammetry.The effectiveness of the diaphragm contraction in relation to the ribcage was observed with trunc-surface deforrnations.The thorax-wall of new-borns and sucklings are pliable:the diaphragm action sipps the ribcage. Growing childrens thorax can resist against this sipping effect, but practically they have no thoracal, only abdominal breathing.Later in childhood the thoracal breathing type developps individually. Introduction Since 1974 I have the honour to participate with my papers on several Biostereometrics Session. At that time I had 15 years of Photogrammetry study of the breathing movements behind me. Based on Photogrammetrical documentations I worked with manual geometry, constructing my designes,hoping, that I can elaborate a model-method and to grope around the photogrammetrical possibilities in the study of the mechanism of the human breathing pump-system. Using a ruler and a pair of compasses, with steady obstinacy I arrived to realise three abstractions:Spatial; spatiotemporal analysis informations and the velocity or the acceleration factors, this last one being the most sensitive. Recently I made the-first steps to study four dimensional information, with two time factors.
