1st International Conference on Advancements of Medicine and Health Care through Technology, MediTech2007, 27-29th September, 2007, Cluj-Napoca, ROMANIA Timing Life Processes Dana Baran Abstract — Natural clocks such as planet movements and biological timekeeping gears inspired artificial timers including water clocks, sandglasses, mechanical, electric and finally electronic systems. Contemporary medicine and biology reconsiders temporal morphogenetic and functional patterns interpreting life processes as highly sophisticated clockworks, liable to mathematical modelling and quantification. Chronobiology and chronomedicine opened a vast theoretical and applicative field of interest. Keywords: chronobiology, temporal monitoring devices, biological clock, mathematical modelling. 1. INTRODUCTION exogenous synchronizers periodically adjust to the cosmic time.

Largely known as chronobiology, it lately generated a medical subdivision: chronomedicine. 3.

[5, 6] According to Philolaos of Giovanni da Dondi (1318-1389), professor of astronomy, Crotona (V-th century BC), health resulted from the logic and medicine at Padua and of medicine at Florence cosmic harmony he called “eurhythmics”. Hippocrates Universities, technically featured an astronomical clock himself, in the same golden age of the V-th century BC, containing an escapement composed of a band-saw crown believed in the significance of critical days for anticipating wheel and a verge.

He also recognised chronopathological aspects: humanists turned to encyclopedists, and mechanistic diurnal or nocturnal incidence of acute episodes, seasonal philosophers substituted both wizards and alchemists.[9] occurrence of certain diseases. Galen (II-nd century AD) instead had often recourse to astrological medicine. [5, 6] 7.2.

Nevertheless, as yet, physicians did religious institutions which were particularly concerned not abandon their zodiac books since astrological medicine with strict timekeeping. Saint Augustin, Dionysius maintained its high profile. Paracelsus (1493-1541), the Exiguus, - a Danubian Scythian by birth-, venerable Beda symbol of iatrochemistry, was such an emblematic or Alcuin were among the early most famous personality. Besides, he kept on being a successful contributors. [7] Not only were new calendars conceived, alchemist.

Subsequently, a profane destinies, - “in season and out of season”, more adequate quantification of time-related bioreactivity reflecting and emphasizing God`s messages.

Heart rate and wrist pulse constituted reference clocks were present, for instance in Malta, in every place, oscillators Galilei (1564-1642) used to consult in Pisa aimed at getting rid of devil`s sinister impact upon cathedral for evaluating the candelabrum-pendulum humans.
