The electrosleep therapy (Somlec therapy) is an altificiai sleep similar to tiormal one induced b보 external stimulus of low voltage electric current to scalp surface which relaxes or inhibits cerebral nerve cells. Since A. W. Filomafitcky, a Russian physiologist, first studied in 1836 CNS response of human-beings to electric current, the technique of psychiatric treatment called electrosleep therapy had greatly expanded in Soviet Union for about 20 years. In fecelit it has become much cohceflied in Europe and America. The author reviewed the references to the technique and method, sleep mechanism, various action and function of the electrosleep therapy. Here, the author reports the clinical experience to the response and results of the electrosleep therapy applied in 17 selected cases of patients having insomnia and psychic tension with other psychiatric symptoms

The purpose of this study was to investigate the effect of aquarobic exercise on health-related physical fitness and immune functions in elderly women. Statistical Data was processed by SPSS(Windows Version 12.0) using descriptive statistics regarding the physical characteristics of subjects as well as each variables(health-related physical fitness and immune functions). The difference of within and between in two group was analyzed repeated measures ANOVA, significant level was set a=.05. The results were as follows: Health-related physical fitness, there was significant difference according to the measurement, Immune functions, there was significant difference according to the measurement, From the results, We findings suggest that elderly women could improve their health-related physical fitness and immune functions through aquarobic exercise program.

The purpose of this study was to investigate the effect of video circuit exercise on body compositions and health-related fitness in obese middle-aged women. Statistical Data was processed by SPSS(Windows Version 12.0) using descriptive statistics regarding the physical characteristics of subjects as well as each variables(body compositions and health-related fitness). The difference of within and between in two group was analyzed repeated measures ANOVA, significant level was set a=.05. The results were as follows: Body compositions, there was significant difference according to the measurement, Health-related fitness the results, Therefore, our findings suggested that the video circuit exercise in middle-aged obese women may have positive effects on prevention of metabolic diseases related to lifestyle.

The purpose of this study was to investigate the effect of bosu ball exercise on fall risk and walking ability in elderly women. Statistical Data was processed by SPSS(Windows Version 12.0) using descriptive statistics regarding the physical characteristics of subjects as well as each variables(fall risk, walking ability). The difference of within and between in two group was analyzed repeated measures ANOVA, significant level was set a=.05. The results were as follows: Fall risk, there was significant difference according to the measurement, Walking ability, there was significant difference according to the measurement. From the results, We findings suggest that elderly women could improve their balance and walking ability through bosu ball exercise program.
Potentiometric performance of flexible pH sensor based on polyaniline nanofiber arrays
최봉길,이경균,Jo Hee Yoon,Hong Jun Park 나노기술연구협의회 2019 Nano Convergence Vol.6 No.9
We report potentiometric performance of a polyaniline nanofiber array-based pH sensor fabricated by combining a dilute chemical polymerization and low-cost and simple screen printing process. The pH sensor had a two-electrode configuration consisting of polyaniline nanofiber array sensing electrode and Ag/AgCl reference electrode. Measurement of electromotive force between sensing and reference electrodes provided various electrochemical properties of pH sensors. The pH sensor show excellent sensor performances of sensitivity of 62.4 mV/pH, repeatability of 97.9% retention, response time of 12.8 s, and durability of 3.0 mV/h. The pH sensor could also measure pH changes as the milk is spoiled, which is similar to those of a commercial pH meter. The pH sensors were highly flexible, and thus can measure the fruit decay on the curved surface of an apple. This flexible and miniature pH sensor opens new opportunities for monitoring of water, product process, human health, and chemical (or bio) reactions even using small volumes of samples.
