다국어 초록 (Multilingual Abstract)

The purpose of this study is to observe in the asopect of bio-electrics from the effect of static electricity, which is generated from our clothes made synthetic fibre materials, on our physiloigical function and electric impedance of our body.The experiement has been made on two male college students and two female collge Students under three different dircumastnaces(first, under the circumstance when they waar cotten clothes, second in synthetic fibre clothes and third in synthetic fibre clother given friction) And in each circumstance, quantity of electric charge of clothes, pulse frequency, blood pressure, breath, rate, ECG, EMG and PGR have measured.The following results have been aquired from the above mentioned experiment.The quantity of electric charge is +2∼+3 KV when the subject wears cotton clothes and -6∼-17 KV when it wears synthetic fibre clothes. The quantity of electric charge is about three times as large in the first case as in the last case.Electric charge, when applied to our body form outside, brings some effects in our physiological function, such as the increase of pulse rate and blood pressure.The potential difference of EMG, thougt it is affected by the type of physical activity. varies with the quantity of electric impedance.PGR is affected by static electricity, though the results are also variable according to the condition of experiment and the type of subject.From the facts observer we can conclude that the frictional electricity generated by synthetic fibre clothes has an effect on physi-ogical funcion, electic impedence and PGR.Assuming that we are affected adversely by static electricity, we must say that we add another pollutant to our circumstance which already contains too many polluting substances.And accordingly, we must develop some substances which we use for counter acing such effect. And beside, it is necessary for us to study further the relations between static electricity and sex, constitional difference, physical strength and physical function of an individual.
