The aim of this study was to investigate the combined effects of aerobic training and diacylglycerol ingestion on lipid profiles and resting metabolic rate changes in obese men. The subjects were divided into 3 groups: the Diacylglycerol group (D, n=6), aerobic training group (E, n=6), and diacylglycerol ingestion and aerobic training group (DE, n=6). Diacylglycerol was ingested and aerobic exercise training performed for 12 weeks. The information from the research was calculated through a Windows SPSS/PC+ Ver. 12.0K statistics package to standardize the means and deviations for each group. Then, two-way repeated measures ANOVA was used to evaluate the research hypothesis. Percent body fat, blood lipid profiles and resting metabolic rate changes were tested to evaluate the combined effect of aerobic exercise training and diacylglycerol ingestion. The results of this study were as follows; DG ingestion was shown to have a positive effect on body weight and body fat, while having a negative effect on resting metabolic rate changes. However, aerobic training was shown to have a positive effect on all factors including body weight, body fat, and resting metabolic rate. In conclusion, DG ingestion and exercise training were not shown to have synergistic effects on resting metabolic rate changes, percent body fat and lipid profiles, while aerobic exercise training was shown to have a positive effect on resting metabolic rate changes, percent body fat, and lipid profiles. To investigate the therapeutic effect of DG ingestion and aerobic exercise for obese men, analysis of catecholamine, cAMP, HSL, or insulin sensitivity should be considered.

The purpose of this study is to examine the effect of red ginseng on the performance of aerobics anaerobics exercise and peripheral central fatigue. For this purpose, we measured $\dot{V}O_2max$, $\dot{V}O_2$ at recovery, anaerobic power, blood lactate, Branched-Chain Amino Acid(BCAA) etc in thirty male subjects. They were divided into three group; EGG: endurance training + red ginseng supplementation group(n=7), EPG: endurance training + placebo supplementation group(n=7), GG: only red ginseng supplementation group(n=10). 6 subjects were excepted because they were intermediate test absence(test at four week : EGG=1, EPG=2; test at eight week : EGG=1). EGG and GG took red ginseng twice a day for total 8weeks. Moreover, EGG and EPG were exercised during 45 minutes, three times a week for 12 weeks. The result of this study are shown as follow: In case of $\dot{V}O_2max$, %$\dot{V}O_2$/$\dot{V}O_2max$ and plasma BCAA concentration, no statistically significant change were found among three groups. But, it was showed that three groups tended to increased slightly in $\dot{V}O_2max$, % $\dot{V}O_2$/$\dot{V}O_2max$ and plasma BCAA concentration. For conclusion, the present data provide a new evidence that ingestion of ergogenic aids contained with red ginseng may improve aerobic exercise performance and central fatigue.

Overweight and abdominal obesity caused by sedentary lifestyle may induce deconditioned and atrophied extensor musculature of the lumbar spine and be a potential risk factor for low back pain (LBP). Therefore, this study was conducted to evaluate the validity of high intensity circuit training (HICT) on weight loss and subsequent alleviation of spine curvature (SC) and visual analog scale (VAS) among middle aged men with abdominal obesity. The training program (1 exercise session for 30 minutes, three times a week for 12 weeks) consisted of 12 different functional exercises based on core strengthening multiple joint circuit training. Portions of the obesity index related to body composition were positively changed, which improved the angles of thoracic kyposis and lumbar lordosis, which appeared to effectively reduce lower back pain. Taken together, HICT specifically designed for LBP effectively decreased obesity related body composition and was superior to other treatments for decreasing aggravation of the spine curvature and LBP caused by abdominal obesity; however, weight loss should be the primary treatment target for LBP patients.

The purpose of this study was to investigate the effects of 12-week aerobic exercise training on cardiac QT intervals and cardiovascular risk profiles in type 1 diabetic children. Eleven type 1 diabetic children aged 9-17 years took part in this study as subject. The participants performed aerobic exercise training three times a week for total 12 weeks. The intensity of the training was adjusted at HRR 45% until three weeks and at HRR 55% since four weeks. After a 12-week aerobic exercise training systolic (p<0.05) and diastolic (p<0.05) blood pressure of the subjects was decreased. There was significant decrease in cardiac QT intervals (p<0.05), TC level (p<0.05), and HDL-C level (p<0.05). Therefore, the results of this study suggest that long-term regular physical activity of type 1 diabetic children considered exercise intensity and frequency may effect and play a important role in the prevention of diabetic complications and cardiovascular health care.

Purpose: This study was conducted to evaluate the effectiveness of autogenic training on stress responses through a systematic review and meta-analysis. Methods: A systematic search was conducted using eight core electronic databases (Embase, CENTRAL, Medline, CINAHL, PsycInfo, DBpia, KISS, and RISS). To estimate the effect size, a meta-analysis of the studies was performed using RevMan 5.3.5 program. Results: A total 21 studies out of 950 studies were included in the review, and 11 were included for meta-analysis. These studies showed that autogenic training decreased anxiety and depression, and increased the high frequency of heart rate variability. Calculations to understand the effect of autogenic training on anxiety, through a meta-analysis, observed a reduction effect of anxiety score by 1.37 points (n=85, SMD=-1.37: 95% CI -2.07 to -0.67), in the studies on short-term intervention targeting healthy adults. On the other hand, similar calculations to understand the effect of autogenic training on depression observed, a reduction effect on the depression score by 0.29 point (n=327, SMD=-0.29: 95% CI -0.50 to -0.07), in the studies on long term intervention targeting the patient group. Conclusion: Autogenic training is effective for adults' stress management, and nurses will be able to effectively perform autogenic training programs for workers' stress relief at the workplace.

PURPOSE: This study investigated the protective role of high-intensity interval training against acute liver injury induced by D-galactosamine (D-Gal)/lipopolysaccharide (LPS). METHODS: A total of 30 male BALB/c mice aged 5-week were randomly assigned to high-intensity, interval training group (EX, n=10) or control group in cage (Non-EX, n=20) for 10 weeks. Peritoneal injection of D-Gal (700 mg/kg body weight) and LPS ($10{\mu}g/kg$ body weight) was applied to induce acute liver injury, and liver tissue was harvested 6 hours after the injection. Hematoxylin and Eosin (H&E) staining was used for liver histology. Real-time PCR was used to quantify expression of pro-inflammatory and anti-inflammatory genes in the liver. RESULTS: The liver histology showed that D-Gal/LPS treatment resulted in hepatic damage and increased number of neutrophils in conjunction with upregulation of hepatic IL-6 and $TNF-{\alpha}$ mRNAs and downregulation of hepatic $PPAR{\alpha}$ and SIRT1 mRNAs. On the other hand, the 10-week interval training resulted in a significant improvement in cardiorespiratory fitness assessed as run time to exhaustion on a treadmill. In addition, the interval training attenuated the D-Gal/LPS-induced liver damage and increased number of neutrophil in conjunction with downregulation of hepatic IL-6 and $TNF-{\alpha}$ mRNAs and upregulation of hepatic $PPAR{\alpha}$ and SIRT1 mRNAs. CONCLUSIONS: This study suggests that high-intensity interval training suppresses the D-Gal and LPS-induced acute liver damage and inflammatory responses.

The purpose of this study was to determined the converge effects of weight-bearing exercise on lumbar, femur neck BMD and body compositions in intellectual disabilities and normal men. Nineteen men were participated for this study, they are divided into two groups(intellectual disabilities, n=9, and normal men, n=10). All subjects are accomplished on weight-bearing exercise (music rope-jumping) program for 60 minutes a day, 3 days a week throughout 12 weeks. Two-way ANOVA with repeated measures was used to determine differences between and within the intellectual and normal groups for dependent variables. The statistically significant level was set at 0.05. In this study, there were a significant differences on the bone mineral density of lumbar and femur neck level after exercise training in both groups (respectively p<.01, p<.001). Also, I found that there were effectively decreased on body weight, percent of body fat, and BMI levels after exercise training for 12 weeks in both groups (respectively p<.001). Therefore, music rope-jump exercise program may suggested to be one of the ideal training methods for enhancing and the convergence positive effect of bone mineral density and body compositions in intellectual and normal person.

Active Appearance Models(AAMs)은 얼굴인식, 얼굴추적, 표정인식 뿐만 아니라 눈동자 추적과 같은 분야에도 적용되어 좋은 성능을 보여 주었다. 보통 AAM 을 생성하기 위해서는 얼굴 영상과 얼굴의 특징을 나타내는 점으로 구성된 매쉬로 이루어 지는 트레이닝 셋이 필요하다. AAM fitting algorithm 은 학습한 얼굴과 유사한 얼굴을 Fitting 할 때에는 뛰어난 성능을 보이지만 조명에 의한 그림자 또는 액세서리에 의한 얼굴의 피부 가림과 같이 전체 얼굴이 잘 나타나지 않는 불완전한 영상의 Fitting 은 입력영상과 템플릿 영상간의 오차가 커지기 때문에 실패할 가능성이 매우 높다. 본 논문에서 우리는 AAMs 에서 사용되는 PCA를 Higher-order Singular Value Decomposition(HOSVD)로 대체하여 이 문제를 보완하는 강화된 AAM 을 제안한다. 제안된 AAM 에는 기존에 사용하던 고유벡터와 함께 HOSVD 를 통해 획득할 수 있는 Eigen-Modes 를 추가하여 사용한다. 또한 우리는 Yale Face Database를 이용한 평가를 통해 제안된 AAM 이 기존 AAM 보다 불완전한 영상에 효과적으로 대응하는 것을 보여준다.
