In this paper, AI methods such as deep learning are applied to provide customized exercise therapy for patients with kidney disease. In order to apply deep learning, a dataset that can determine kidney disease is trained to determine whether it is a kidney disease, and 1RM, which is the user's physical information and muscle strength according to whether it is a disease, can also be calculated through deep learning. The calculated muscle strength of 1RM was converted into resistant exercise for each part through a calculation equation for each part of the body, and was configured to be provided with an aerobic exercise amount tailored to the user's body information. If continuous research is conducted in the manner proposed in this paper, customized exercise therapy can be provided for various diseases.

Adiponectin and Gut hormones(insulin, glucagon, ghrelin, PYY and GLP-1) are recently discovered peptides that are associated with lipid metabolism, insulin resistance, and control appetite. The purpose of this study was to investigate the effects of acute treadmill exercise(walking, 45min ; all-out running, 5min) on Adiponectin and gut hormones in high school ssireum player(light class, n=8; heavy class, n=8). From the experimental results, Adiponectin and ghrelin of light class were significantly higher than heavy class(p<.05), but there was no difference between pre and post exercise. Insulin level of heavy class was significantly higher than that of light class(p<.01) and no difference between pre and post exercise. Only glucagon significantly increased after exercise(p<.01), but no difference between classes. PYY and GLP-1 were no difference on classes and pre vs. post-exercise. The result of this study suggest that adiponectin, ghrelin and insulin were affected by body weight(light class vs. heavy class) and glucagon was affected by acute exercise.

The effects of a 12-week weight reduction program applied to obese women at a community health center were studied. Middle aged women participated in the beginning of the program, but 34 persons finished the study (85% completion). Subjects practiced belly dancing three times a week for 60 minutes (60~85% HR max) per session, and nutritional education was carried out four times during the 12 week program. The weight, %body fat, and BMI significantly decreased by 5.6%, 9.5%, and 5.6%, respectively. The concentrations of serum triglycerides, total cholesterol, and LDL-C were also significantly reduced by 13.5%, 9.5%, and 10.4%, respectively. Insulin level was reduced by 19.8%, thus lowering the HOMA-IR index. Leptin level significantly was reduced by 32.35%, adiponectin concentration. Total ROS concentration increased while total antioxidant capacity in serum remained unchanged. In conclusion, a 12-week 'Obesity Clinic Program' belly dancing and nutritional education held at a Community Center seemed to have health-promoting effects through reducing body fats, plasma lipids, and improving insulin resistance.

In the elderly, a lower muscle mass and higher body fat mass are induced by a lower level of physical activity. A negatively changed body composition with an advanced age can lead to a higher falling risk and rate of diseases. On the other hand, aerobic-type exercise positively influences the body composition and hyperlipidemia in the elderly. Therefore, this study examined the effects of aquarobic training for 12 weeks on the body composition and blood lipid levels in obese old women. The subjects (n = 31, body fat: 33.42%) completed a 12 week water based aerobic training at 12 - 13 of Borg Scale of intensity (three times per week, each session: an hour). The body composition was measured by bioelectrical impedance analysis (Inbody 770-Biospace, Seoul, Korea) and the concentrations of blood lipids (high-density lipids cholesterol (HDL), low-density lipids cholesterol (LDL), triglyceride (TG) total cholesterol (TC)) were determined at pre and post training. A paired t-test was used for data analysis with ${\alpha}=0.05$. In the results, the body composition (% body fat (p < 0.05) and waist circumference (p < 0.05)) were reduced significantly. The LDL (p < 0.05), TG (p < 0.001) and TC (p < 0.05) were reduced significantly. In conclusion, a 12 week aquarobic exercise program helps improve the body composition and concentrations of serum lipids. Therefore, aquarobic exercise can enhance lipolysis using fat as energy to induce an improvement of the body composition and induce hyperlipidemia.

The purpose of this study was to determine the possible additive effects of endurance exercise training (EXER) and selenium (SELE) on the improvements of glucose and lactate transport capacities in diabetic Goto-kakizaki rats. Animals either remained sedentary control (SED) or performed EXER or received SELE [$5{\mu}mol$ kg body wt (-1) day (-1)], or underwent both EXER and SELE (COMBI), which lasted for 6 wk. Compared with sedentary control, EXER alone or the SELE alone group, or the combined treatment group had significant reduction in glucose response measured at 90 min and 120 min during an intraperitoneal glucose tolerance test (IPGTT) and body weight after 6week treatment. EXER alone, or combined group individually had significantly higher glycogen contents in liver compared with SED or SELE groups. EXER alone increased glycogen content in soleus and plantaris compared with SED, and this parameter was increased to greatest extent in the combined treatment groups compared with SED or SELE groups. EXER alone, SELE alone or COMBI, caused significant decreases in the plasma lactates, serum glucose, insulin, total cholesterol and HOMA-IR along with a significant increase in high-density lipoprotein cholesterol compared with SED. In addition, EXER or COMBI individually had significantly lower serum triacylglycerol compared with SED or SELE. With respect to protein expression related to glucose and lactate transport capacities, EXER alone, SELE alone, or COMBI increased in MCT1 and MCT4 protein level in soleus and plantaris. Furthermore, EXER alone, SELE alone or COMBI caused significant increases in mt MCT1 protein level in soleus and plantaris. The findings of the current study suggest that endurance exercise training and selenium treatment may provide therapeutic values to type II diabetic patients with peripheral insulin resistance and hyperlactatecemia by improving glucose and lactate transport capacities, leading to improvements in plasma lactate, serum glucose, insulin and lipid profiles (TC, TG, HDL).

This study was performed to provide detailed and comprehensive information on inflammation-related blood indicators, joint range of motion, pain scale, and psychological indicators by patient characteristics by performing a 12-week home-based exercise program for ankylosing spondylitis patients. For the purpose of this study, 10 patients with ankylosing spondylitis were selected by age (30s vs. 40s vs. 50s), gender (male vs. female), and duration (less than 5 years vs. 5 years or more). The home-based exercise program was a combination of aerobic exercise and Pilates-based resistance exercise, and was performed 4 times a week for 12 weeks at an intensity of 50-70% of maximal heart rate (MHR). As a result, after 12 weeks of home-based exercise intervention, the blood C-reactive protein (CRP) concentration of patients with ankylosing spondylitis decreased (-35.6%, p=.002), and the blood inflammation level was improved, and each joint (hip, lumbar, cervical) improved mobility (p<.05). In addition, the bath ankylosing spondylitis disease activity index (BASDAI) was decreased by -67% (p=.001) and the visual analogue scale (VAS) was decreased by -64.8% (p=.001), stiffness and pain has been alleviated. In particular, as the degree of depression decreased by -65.5% (p=.001) and the degree of anxiety by -55.2% (p=.003), 12 weeks of home-based exercise improved not only physical changes but also psychological factors. On the other hand, there was no difference in exercise effect according to age, gender, and disease duration in ankylosing spondylitis patients (p>.05). These results suggest that the 12-week home-based exercise applied in this study can be an effective exercise program that can be universally used for ankylosing spondylitis patients regardless of patient characteristics.

홍수터에 식재된 수목에 의한 운동량 교환은 흐름의 추가적인 흐름저항으로 작용한다. 따라서 수목으로 인한 통수능의 감소로 부분적인 유속 상승이 발생하기도 하지만, 전반적으로 평균유속이 감소하며 수위는 상승하게 된다. 실무적 사용목적으로 홍수터 수목의 저항은 통합 매개변수인 합성조도계수가 사용되고 있으나, 정량적인 조도계수의 추정은 매우 어려운 문제이다. 본 연구에서는 경험적으로 추정되는 비정량적 합성조도 계수의 한계를 극복하고, 실무적으로 사용이 용이하도록 수목에 의한 흐름저항 항을 분리한 1차원 상류이송 음해기법이 개발되었다. 개발된 기법의 평가를 위하여 균일한 단면에서 수행된 수리실험에 적용하였으며, 다양한 유량규모 및 식재조건에서 제안된 기법의 적용성 및 정확성을 확인하였다. 불규칙한 단면형상을 가진 실제 하천의 홍수터에 식재된 수목군의 경우를 가정하여 1/25 정상축척의 수리실험을 실시하였고, 100년 빈도 홍수량에서 수목식재 전후의 실측결과를 개발된 수치기법으로 계산하여 비교하였다. 개발된 기법은 모든 경우에서 사용자의 주관적인 판단 없이 정확하면서 안정적인 해를 제공하였으므로, 흐름의 2차원 효과가 상쇄될 수 있는 광폭의 자연하천에서 수목의 식재기준 분석을 위한 대안으로 사용될 수 있을 것이다.

선박 고속화와 해양레저선박에 대한 관심 증대로 쌍동형 선체건조가 증가하고 있으며 일반적으로 쌍동형 선체는 복원성, 내항성능 및 저항추진 등에서 단동형 선체보다 고속선형 및 갑판활용에 적합하다고 알려져 있다. 하지만, 쌍동형 선체는 갑판 상에서 두 개의 선체를 동체로 결합시킨 선체로서 운동 시 부체 간 공진현상이 수반된 자유표면 거동과 유체력이 발생할 수가 있다. 따라서, 이 논문에서는 이런 공진현상을 감쇠시킬 수 있는 방안을 모색하여 합리적인 쌍동형 선체의 운동응답특성과 동유체력을 산출하였다.
