The purpose of this study was to investigate the changes of body composition, physical fitness and blood components after 12 weeks Taekwondo Fom training. Subjects were consisted of total 22 people with 12 man, 9 women in K university Taekwondo circle students. First, the characteristic of body composition was not significant in mineral(p>.05), but protein was significant in women group(p<.05). And somatic fat rate, abdominal district rate was significant higher(p<.05) in man group and women group. Second, the characteristics of their physical fitness was not significant in grip(p>.05), but standing tunk flexion, jumping reaction time, foot balance with closed eyes, vertical jump was significantlpx.Ifi in man group and women group. Third, the characteristic of blood components was not significant in TC(p>.05), but TG, HDL-C was significant(p<.05) in man group and women group. As a result of this study, because affirmative influence extended to a body composition, physical fitness, blood components, Taekwondo Fom training appeared for 12 weeks. It is thought that study of a book should be offered to development of Taekwondo Fom with a base document through a scientific approach for Taekwondo Fom.
The purpose of this study was to investigate an effects of dietary restriction and aerobic exercise program on metabolism regulatory hormone and % body fat in response to 12 weeks. Thus, whether the weight reduction pattern was associated with differences of weight loss in obese women submitted to a weight loss program which included dietary restriction and aerobic exercise. For this study, 16 middle aged obese women of 35% body fat mass were chosen as subjects. This subjects were divided into two groups as random sampling(dietary restriction group;n=8 and aerobic exercise group;n=8). Dietary restriction group carried on restriction of 500 calory per day, full times a week for 12weeks. aerobic exercise program two hour a day, five days of week for 12weeks. Before and 4weeks, 12weeks after the intervention hormone variables and body composition variables were measured. Statistical technique for data analysis were two way ANOVA was done to detect differences among groups at each point and the significant differences(p<.05) were identified. The experimental results from this study are the following. 1. As a results of the aerobic exercise group weight reduction program were significantly decreased body weight(p<.05). but two groups were not significantly % body fat(p>.05). 2. As a result of thyroxine level were significantly increased in two groups(p<.05) 3. As a result of insulin and cortisol level were not significantly in two groups(p>.05). 4. As a result of FFA level were significantly decreased in two groups(p<.05). In conclusion, we couldn't see that reduction of weight with about 500kcal of diet from differentiation case of method of the diet, so we can expect that greatest effect if we're going to exercise with the diet. especially the case of aerobic exercise. we think that will help our diet if we can keep going this exercise more than an hour. and we can get the result 'thyroxin and free fatty acid' from diet. we think that diet bring about affirmative result into the hormone as well.
The performance of a photovoltaic array is affected by temperature, solar insolation, partial shading effect, and array configuration. Maximum power point tracking(MPPT) techniques are employed in photovoltaic systems to make full utilization of the PV array output power which depends on solar irradiation and ambient temperature. As much as MPPT is important in photovoltaic systems, many MPPT techniques have been developed. In this paper, several major existing MPPT methods are comparatively analyzed and novel hybrid MPPT algorithm is proposed. The proposed hybrid MPPT algorithm is developed in combination with traditional MPPT methods to complement each other for improving performance and mitigating partial shading effects. The proposed algorithm is implemented and validated using MATLAB/Simulink simulation tool.
This study aims to examine the effects of 12 weeks of D-ribose supplementation and resistance training on body composition, changes in anaerobic exercise capacity (Wingate test), stress hormones and muscle damage enzymes. Thus, it examined female university students in their 20s who have no regular exercising experience by dividing them into RI(D-ribose intake) group of 6 members and PL (Placebo) group of 6 members, and came up with the following conclusion. Steady and regular exercise prevented muscle damage in carrying out acute exercise, and steady intake of D-ribose plays the role of increasing the ability to recover from acute exercise. Steady D-ribose intake clearly helped improve physical fitness, but it must be noted that low-intensity and little exercise may lead to weight gain.
The purpose of this study is to understand if ATP supply promotion, which is induced by D-ribose taken during high intensity anaerobic exercise, is effective in showing explosive and strong power and what kind of things it influences on stress hormone after taking D-ribose and practicing resistance exercises for 12 weeks. Thus, it examined male university students in their 20s who have no regular exercising experience by dividing them into RRT(ribose+resistance training group) 7 members and PRT(resistance training group) 7 members, and then they took 40 ㎎ D-ribose/weight dissolved in 200 ml drinking water for 12 weeks. PRT group took placebo(refined sugar, 2g) dissolved in 200 ml drinking water in the same way. The exercise program was the weight training; during 1st-6th weeks 2 sets of 15 repetition at 60% of 1-RM, and during 7th-12th weeks 3 sets of 15 repetition at 70% of 1-RM. The statistical technique used was two-way ANOVA and paired t-test as post-hoc analysis. Experiment result is as followings: 1. In body composition change there was no interaction between body fat percentage and lean body percentage, but the body fat percentage was decreased and lean body percentage was increased in 12th week compared with prior ones in both RRT and PRT. 2. In anaerobic exercise capability there was no interaction in all items, and PP, AP and MP were increased in 12th week in both RRT and PRT compared with prior ones, and PD was decreased in 6th and 12th weeks in both of RRT and PRT. 3. In stress hormone change testosterone showed no interaction and no main effect. Cortisol was increased in 6th week in both of RRT and PRT compared with prior one. Reviewing the results, both of D-ribose taking+resistance exercise group and resistance group showed positive changes in body composition, anaerobic exercise capability and stress hormone, however there was no difference between the groups. Hence, there was no synergy effect from D-ribose taken.
Unintentional islanding results in safety hazards, power quality degradation, and many other issues. Thus, islanding detection of grid-connected distributed generation system is a key function for standards compliance. Many anti-islanding schemes are currently being studied; however, existing anti-islanding schemes used in inverters have power quality degradation and non-detection zone issues. Therefore, this paper analyzes existing anti-islanding schemes by using frequency drift in accordance with both islanding detection performance and power quality. This paper also proposes a new anti-islanding scheme by using frequency drift. Both simulation and experimental results show that the proposed scheme has negligible power quality degradation and no non-detection zones compared with other existing schemes.
