The purpose of this study is to identify physical activity levels of the basic livelihood security recipients elderly women, to investigate relation between cardiovascular disease risk factors and sacrcopenia based on the levels, and to develop physical activity programs for healthy life of the elderly. The subjects of this study were 134 old females with $71{\pm}6.67$ years old who used senior centers in K-gu. The authors used the International Physical Activity Questionnaire for investigating the physical activity levels of the elderly, measuring their physical activity levels for seven days on average and classifying them into two groups, the Low Physical Activity (n=77) and the Moderate Physical Activity (n=57) groups based on the levels. Blood pressure, waist measurement, TC, HDL-C, LDL-C, TG, Glucose, and atherogenic index (AI) were measured as the cardiovascular disease risk factors; percent body fat, appendicular skeletal muscle mass, total muscle mass, and skeletal muscle index were measured as factors related to sarcopenia. Independent samples t-Test was conducted to analyze differences on the two groups based on the physical activity levels, with ${\alpha}=.05$ the as significance level. According to the results, HDL (p=.017) were higher and AI (p=.007) was lower; percent body fat (p=.008) was lower, and ASM (p=.000), total muscle mass (p=.000), and SMI (p=.001) were higher. In conclusion, moderate intensity physical activities rather than low intensity ones may have positive effects on the cardiovascular disease risk factors and sarcopenia levels, and participation in regular physical activities with at least moderate intensity by various methods may be needed for prevention of illness and healthy life of the elderly.

This study was performed to report the effectiveness of modified fasting therapy using very-low-calorie-diet on a patient with obesity. The patient was diagnosed as severe obesity and participated in a 14-day fast with the Signature, a liquor which is made from fermented medical herbs and carbohydrates (intake <600 kcal/day) accompanying 7 prefasting relief days, and 16 days with stepwise reintroduction of food. The fasting patient also received intensive oriental medical treatments such as acupuncture, moxibustion, cupping therapy and was encouraged to take more than two hours' of walking exercise a day. We have evaluated the efficacy of treatments by measuring the changes of body composition and blood chemistry according to each period of fasting therapy. After treatment, Body Fat Mass of the patient was decreased more than Muscle Mass and the level of AST, ALT was decreased to normal range. These results suggest that the modified fasting therapy was effective on the patient with obesity.

The purpose of this study is to verify the difference in health and obesity according to water and coffee intake. The study subject is 900 female college students. Physical fitness factors measured in this study were physical strength(grip strength, back muscle strength), muscle endurance (sit-up), Flexibility(Sit & reach) and cardiopulmonary endurance(harvard step). The factors of body composition (intracellular fluid, extracellular fluid, protein, mineral, body water content, muscle mass, lean body mass, body fat mass) and obesity (BMI, body fat percentage, abdominal fat percentage, obesity) were measured with the Inbody equipment. SPSS program was used for all data analysis. Group differences were verified by two-way ANOVA and one-way ANOVA. The results are as follows. There was no interaction effect between water and coffee intake on health and obesity. Therefore, the difference of the dependent variables according to each independent variable was verified. There was no significant difference in physical fitness according to water intake and coffee intake, but there was a significant difference in body composition (intracellular fluid, protein, minerals, body water, muscle mass and lean body mass). Water drinking group more than 7 cups had significantly higher body composition than the 1-4 cups water drinking group. In the case of coffee, the body composition of the 3 cup intake group was significantly higher than that of the none intake group. Obesity was significantly higher than the none intake and 1-2 cup intake groups. Based on the study results, water intake was not related to obesity, but coffee was related. For further studies, it would be better to consider gender and age differences in drinking various beverages such as water and coffee and that would be used to suggest a desirable way of water intake according to individual characteristics of the better health.

Lifelog is a digital record of an individual collected from various digital sensors, and includes activity amount, sleep information, weight change, body mass, muscle mass, fat mass, etc. Recently, as wearable devices have become common, a lot of high-quality lifelog data is being produced. Lifelog data shows the state of an individual's body, and can be used not only for individual health care, but also for causes and treatment of diseases. However, at present, AI/ML-based correlation analysis and personalization are not reflected. It is only at the level of presenting simple records or fragmentary statistics. Therefore, in this paper, the correlation/relationship between lifelog data and disease, and AI/ML technology inside lifelog data are examined, and furthermore, a lifelog data analysis process based on AI/ML is proposed. The analysis process is demonstrated with the data collected in the actual Galaxy Watch. Finally, we propose a future convergence service roadmap including lifelog data, diet, health information, and disease information.

아나보릭 스테로이드인 nandrolone phenylpropionate(NPP)가 인슐린에 의한 지방축적의 증가 및 절식시 혈중 유리지방산 농도에 미치는 영향을 암컷쥐에서 조사하였다. 인슐린 투여는 식이 섭취량을 유의적으로 증가시켰는데 이는 인슐린에 의한 혈당 저하에 의한 것으로 보인다. 지방 축적은 인슐린 투여에 의해 유의적으로 증가하였으나 체단백질이나 근육단백질 함량은 변화하지 않았다. 인슐린에 NPP를 동시에 투여하였을 때 NPP는 인슐린에 의한 저혈당증과 지방축적의 증가를 부분적으로 완화시켰으며 체단백질과 근육단백질 함량을 유의적으로 증가시켰다. 반면 NPP는 절식시킨 쥐의 혈중 유리 지방산 농도에는 영향을 미치지 않았다. 이러한 결과를 통해 아나보릭 스테로이드가 단백질 대사에 미치는 영향은 인슐린과 무관하며, 아나보릭 스테로이드의 지방축적 억제효과는 아나보릭 스테로이드가 지방분해에는 영향을 미치지 않고 인슐린에 의한 지방함성으로의 당이용도를 저해함으로 발휘된다는 것을 알 수 있다.

This study examined the effects of four herbal sports drinks containing Prunus mume, Liriope platyphylla, and Acanthopanax senticosus fruit extracts on body fat and endurance of rats trained by a progressive loaded exercise program. Forty male Sprague-Dawley rats (6 weeks old) were divided into five groups and fed experimental diets for 6 weeks according to the following protocol: C, exercise-trained control group (n=8); A, exercise group with Acanthopanax senticosus extract (n=8); L, exercise group with Liriope platyphylla extract (n=8); PA, exercise group with Prunus mune fruit extract plus Acanthopanax senticosus extract (n=8); PL, exercise group with Prunus mune fruit extract plus Liriope platyphylla extract (n=8). Endurance was measured by a progressive loaded exercise test using a treadmill. PA and PL supplementation significantly extended time to exhaustion compared to the control group (p<0.05). Further, the four herbal sports drinks all significantly reduced epididymal and interscapular white adipose tissue weights compared to the control group (p<0.05). Plasma triglyceride concentration was significantly lower in the A group compared to the control group. Plasma free fatty acid concentration was higher in the A group compared to the control group. On the other hand, Acanthopanax senticosus fruit extract supplementation tended to reduce the plasma glucose concentration compared to the control group. PA and PL supplementation significantly increased gastrocnemius muscle LDH activities compared to the control group (p<0.05). These results show that sports drink containing Acanthopanax senticosus improved endurance capacity, plasma lipids, and glucose concentrations. Sports drink with Prunus mume and Liriope platyphylla or Acanthopanax senticosus was synergistically improved endurance.

본 연구에서는 비타민 $B_{2}$ 결핍이 3일간 금식과 6일간 감식시 체내 저장연료 이용에 어떠한 영향을 미치는 가를 알아본 결과, -B2군은 pair-feeding을 감식시켰음에도 불구하고 +B2군에 비해 체중이 유의적으로 낮게 나타났으며 식이 이용효율도 낮았다. 모든 장기, 특히 간장 무게는 -B2군이 +B2군에 비해 무겁게 나타났으며, 감식과 금식시에도 -B2군의 장기무게가 가벼워졌으나 여전히 유의하게 무거웠으며 -B2군의 간장 중성 지방이 높게 나타나 지방간 증상으로 간장이 비대해진 것으로 추정된다. 혈장 포도당과 단백질 함량은 섭식, 금식 및 감식시 +B2군과 -B2군 사이에 유의적인 차이가 없었다. 혈장 중성지방 수준은 +B2군에 비해 -B2군이 섭식시는 높은 수준을 나타냈으나 금식 및 감식시에는 유의적인 차이를 나타내지 않았다. 간장 중성 지방도 이와 유사한 경향을 나타내었다. 혈장 유리지방산 수준은 섭식시에는 +B2군과 -B2군 사이에 유의적인 차이가 없었으나, 금식으로 인해 +B2군은 유리지방산 수준이 증가하였고 -B2군은 오히려 감소하여 -B2군이 +B2군 보다 낮게 나타났다. 그러므로 비타민 $B_{2}$ 결핍으로 인해 이 유리지방산의 유리가 원활히 일어나지 않았거나, 비타민 $B_{2}$ 결핍으로 인해 지방산화가 저해된 것이 금식으로 지방이 에저지원으로 이용되어야만 하는 상황이 발생하여 감소된 지방산 산화가 다소 회복된 것으로 추정된다. 금식 및 감식시 +B2군에 비해 -B2군이 근육단백질 수준은 높은 경향을 나타내었고 근육 글리코겐 수준은 낮은 경향을 나타내어 -B2군이 심각한 비타민 $B_{2}$ 결핍으로 저지방이나 근육단백질을 이용하지 못하게 됨에 따라 근육 글리코겐을 이용한 것으로 추정된다. 이는 +B2군에 비해 -B2군의 뇨중 총질소 배설량이 적은 것으로도 재확인되었다. 그러므로 금식이나 감식시 체지방이나 체단백질을 이용하는 에너지 보충 적응기전이 일어나야 하나 비타민 $B_{2}$ 결핍상태에서는 이러한 체내 열량공급이 지장을 받게 되며, 체단백질 이용저하로 포도당 신생이 영향을 받아 장기간의 금식 또는 감식시에는 혈장 포도당 수준도 낮아질 것으로 예상된다.
