  • Purpose : The study was designed to identify the change of body alignment according to surface during walking with backpack. Methods : Healthy twenty people(10 men & 10 women) participated in this study. The exclusion criteria were orthopedic and neurologic disease. Initial alignment measurements were performed. Results were evaluated by angle and range from earlobe to acromion, acromion to malleolus and earlobe to malleolus in the GPS system. Results : On the hard surface, the distance and angle from malleolus to earlobe increased after walking with backpack which is 20 % of weight(p<.05). In addition the distance from malleolus to acromion and the angle from earlobe to acromion increased(p<.05). On the soft surface, on the other hand, the distance and angle from malleolus to earlobe decreased after walking with backpack which is 20 % of weight(p<.05). There was no relationship between the change of the surface and the body's alignment(p>.05). Conclusion : Consequently, the body alignment was changed by backpack which is 20 % of weight, but body alignment wasn't changed by the surface. So more study need to be surveyed regard of this.

  • The crystal structures of Nylon 6 films with the changes of pressure, temperature, and the processing time were examined. The accompanying physical property changes such as the weight fraction, the crystallinity, the crystal size, the initial modulus, and the thermal properties, gives the following results. When the sample is processed at 16$0^{\circ}C$, the weight fraction is not changed significantly with varying pressure. However, at 18$0^{\circ}C$ a significant change of the weight fraction was found with increasing pressure above 5 ton/in$^{2}$ so as to increase the crysallinity. As long as the ct transition is concerned we found that it begins from 14$0^{\circ}C$ and is completed at 18$0^{\circ}C$ and 9 ton/$in^{2}$ of pressure with the processing time of 120 min. The increase of the initial modulus is believed to be due to the increase of the number of the tie chains and the tension resulting from the change of the crystal size in the direction perpendicular to the direction of the applied pressure. The meltiong point change is due to the pressurized crystallization was not observed.

  • The present study aimed to investigate rapid weight loss (RWL) and consequent physical and psychological challenges among judo athletes at the national athlete training center in 2017. The following results were obtained. Judo athletes used weight loss methods such as "gradually reduce meal portion," "skip meals," "limit water intake," "wear sweat suit for training," and "use sauna," and had physical and mental distress from such unhealthy weight management practices. Information about weight loss was obtained from "colleagues or senior athletes," "Internet," and "head coach or coach," and not experts such as nutritionists or physicians. Thus, athletes are recommended to employ healthy weight control methods based on advice from experts, such as nutritionists and physicians.

  • A total of 216 day-old broiler chickens were randomly assigned to 6 treatment combined 2 dietary protein regimens (22-20%, 20-18% for starter and finisher, respectively) with 3 times of change (2, 4, 6 weeks) to study the effects of different protein levels and time of change from starter to finisher ration on the performance of broilers. Increasing the dietary protein level resulted in not only a significant increase in the body weight gain and the protein requirement per kg body weight gain, but also an improvement of feed efficiency. However abdominal fat accumulation was decreased by adding incremental levels of protein. On the other hand, the earlier time of change from starter to finisher ration, less\ulcorner\ulcornerbody weight gain and the abdominal fat accumulation. But feed intake and viability were not affected by the dietary protein level and/or the time of change from starter to finisher ration. Income was highest for birds fed 22% and 20% protein diet' starter and finisher, respectively changed from starter to finisher at 4weeks of age.

  • Background & Methods: In order to study the effect of electro-lipolysis-acupuncture, 57 outpatients who have had herbal medication in Kirin Oriental Hospital were devided to two groups; acupuncture-treated group(46) vs non-acupuncture-treated group(11) Acupuncture-treated group was given electro-lipolysis-acupuncture at least two times a week and administered with herbal diet medication, whereas non-acupuncture-treated group was administered only with herbal diet medication. Results: Mean age, body weight and BMI of these two group at the start point of the treatment were $27.22({\pm}7.64)\;vs \;29.09({\pm}8.73),\;67.76({\pm}9.34)\;vs\;67.00({\pm}10.69),\;and\;26.20({\pm}3.02)\;vs\;26.14({\pm}4.10)$ in the order of acupuncture-treated and non-acupuncture groups. After one month of treatment, change rate of body weight, BMI, total fat, percentage of fat was significantly higher in acupuncture-treated group. Also the change rate of arm circumference, hip circumference and thigh circumference was significantly higher in acupuncture-treated group. The change rate of abdominal circumference and WHR of acupuncture-treated group was higher than that of non-acupuncture-treated group with no statistical significance. The circumference reduction rate according to herbal dieting program was higher in this order, abdomen, arms, chest, thighs and hips. On the other hand, chest circumference change rate over weight loss rate, which is the portion no acupuncture treatment was given to, and AMC change rate was higher in non-acupuncture-treated group. Conclusion: These results imply that herbal dieting program combined with electro-lipolysis-acupuncture is more effective on reducing body fat, size reduction of localized obesity and preservation of muscle than herbal prescription only dieting program.

  • This study has been performed to investigate the physical and mechanical characteristics of compaction, volume change and compressive strength for reinforced soil mixed with cement. And confirm the reinforcing effects with admixture such as cement. To this end, a series of compaction test and compression test was conducted for clayey soil(CL) and cement reinforced soil. In order to determine proper moisture content and mixing ratio, pilot test was carried out for soil and cement reinforced soil. And the mixing ratio of cement admixture was fixed 3%, 6%, 9% and 12% by the weight of dry soil. As the experimental results, the maximum dry unit weight(${\gamma}_{dmax}$) was increased with the mixing ratio and then shown the peak at 10% reinforced soil, but the optimum moisture content(OMC) and the volume change was decreased with the ratio increase. And the compressive strength volume change was decreased with mixing ratio increased.
