The Purpose of this research is to examine the effect of the aerobic exercise duration on cardiorespiratory function and body fat. Total 14 divided into two groups 7, for the control group and the other for the experimental group 7. The subjects of experimental group had 8 weeks aerobic program in the given intensity, during which the changes in cardorespiratory function and body fat were measured three times, at each end of 0th, 8th week. The research is comcluded as follows. 1. After 8 Weeks, aerobic exercise brought the decrease of maximum HR and the increase of VE with statistically significant(p<.05). 2. Aerobic exercise brought along the change of fat, especially the decline of the rate of fat and the amount of fat. In conclusion, aerobic exercise helps overweight women to reduce their weights and the amount of fat and to get rid of elements that cause various geriatric diseases. Therefore, overweight women as well as common adults are advised to take aerobic exercises

This study is aimed at investigating the effects of aerobic exercise of female college students on blood lipids and body fat percentage. Twelve female students were selected for this study and each 6 of them were alloted into the control group and experiment group. The experiment group underwent jogging for 12 weeks and its effects on blood lipids and body fat percentage were measured at the 4th, 8th and final week of the jogging program. The outcomes of the experiment could be summarized as follows: 1. As for HDL-C due to jogging, the experiment group showed an eminent increase with statistical significance(p<.05). 2. In case of LDL-C following jogging, there was a great amount of decrease in the experiment group after the exercise with statistical significance(p<.05). In sum, it is revealed from the present study that the prescribed magnitude and length of exercise can be of help for HDL-C and LDL-C that have been recognized as indicators for diseases of adult people.

The aim of the present study is to evaluate effects of Spheroid 9000NS applied to 10 elderly patients with Chronic Low Back Pain. The effects were measured and analyzed by means of MPQWL, VRS, VAS-I and VAS-U after 4, 8 and 12 weeks, respectively, during the 12-week application of the Spheroid 9000NS. From the findings of the measurement and analysis, following conclusion could be drawn: 1. Significant reductions in MPQWL were confirmed at each period of measurement since the use of Spheroid 9000NS(p<.001). 2. Significant reductions were also revealed in VRS at each period of the measurement(p<.001). 3. Significant reductions were also revealed in VAS-I at each period of the measurement(p<.001). 4. The same reductions were found as well in VAS-U 4, 8 and 12 weeks after the application of the Spheroid 9000NS(p<.001). In sum, it may be concluded from the outcomes that the use of Spheroid 9000NS may help reduce drastically Chronic Low Back Pain, mostly effective to remove them speedily and safely. Patients, rehabilitation therapists and health experts are, therefore, recommended to employ the products as safe and effective means to control pains. Continued researches and experiments should further be conducted to collect more data from the larger population of patients with particular diseases in clinical situation, though.
Current Status of Physical Activity in South Korea

The health benefits of physical activity have been well established. However, more than a quarter of the adult popu-lation in the world is insufficiently active (not performing at least 150 minutes of moderate-intensity physical activi-ty per week, 75 minutes of vigorous-intensity physical activity per week, or any equivalent combination of the two), and there has been little improvement since 2001. In South Korea, the prevalence of insufficient physical activity was 54.4% in adults and 94.1% in adolescents in 2020. There was continuous decrease in the prevalence of suffi-cient aerobic physical activity, from 58.3% in 2014 to 45.6% in 2020. However, daily duration of sedentary behavior increased from 7.5 to 8.6 hours in the same period. Interventions to promote physical activity are necessary in vari-ous fields including clinical and policy approaches. As physical activity has decreased during the coronavirus dis-ease 2019 pandemic, safer and more effective strategies to promote physical activity are required.

Although previous studies have shown that Ag nanowire (AgNW) is among the most powerful means to replace the brittleindium tin oxide, physically fexible devices using AgNWs are not yet available on the market mainly because of the insuffcientmechanical robustness of the AgNW-based electrodes. Here we propose a modifed inverted layer processing (ILP) tofabricate mechanically robust, near-foldable transparent conductors by totally impregnating AgNWs just under the surfaceof cured polyvinyl butyral (PVB). A single demerit of the original ILP, low surface coverage of conductive pathways, wasresolved by photo-induced heating of the AgNWs to settle them on a temporary substrate before coating and curing of thePVB. This resulted in wide coverage of conducting pathways on the surface of the AgNWs/PVB without compromisingthe ultralow surface roughness. Furthermore, the high strength and excellent compatibility of the PVB with the AgNWsfacilitated the preparation of near-foldable touch sensors.
