There is a need to develop an app for a caregiver health management that can provide continuous management in response to changes over time, because elderly people have low digital utilization capabilities, difficulty maintaining regular and continuous self-management. Based on this need, this study designed an app with a user-friendly UI and simple structure for the elderly. The app developed in this study supports regular management of health data such as blood pressure, blood sugar, and heart rate, as well as specific information on physical, disease, cognitive, communication, and environment in the care field. The app developed in this study supports care services by automatically entering data through integration with health management devices, automatically analyzing and visually representing recorded data to understand trends and volatility, and adding scalability to connect with various health management and medical support platforms. The effectiveness and satisfaction of the developed app were confirmed to be significant in the field verification results.

Blood flow restriction(BFR) exercise is defined as low intensity and short term exercise using pneumatic pressure belts at the top of limbs, which affects the physiological functions of the body. The purpose of this study was to investigate the effects of walking exercise with BFR on inflammatory index, isokinetic muscle function, and thigh circumference in obese women. Eleven obese women(> BMI $25kg/m^2$ & > body fat 30%) wore pneumatic pressure belts on both femurs and performed walking exercise twice per day, 3 days/wk for 4 weeks (walking 2 min; resting 1 min). Data analysis was carried out using paired t-test. Body weight, BMI, and body fat significantly decreased after exercise(p<.05), and right thigh circumference significantly decreased(p<.05). The concentration of plasma IL-6 significantly increased(p<.05) after exercise. TNF-${\alpha}$ level was not statistically different but tended to slightly increase. CRP slightly decreased, although it did not reach statistical significance after exercise. Muscle strength significantly increased in the $60^{\circ}/sec$ of right/left side extension, left side flexion, and $180^{\circ}/sec$ of left side extension after training(p<.05). These results suggest that 4 weeks of blood flow restriction walking exercise has positive effects on inflammatory index and isokinetic muscle function. Therefore, we consider that blood flow restriction exercise can be used for treatment of obesity, related chronic diseases, and metabolic syndrome. Further, blood flow restriction exercise for a short time has similar effects as a high intensity resistance program.

Through the study on judgment of Body form and settle Energy flow(立形定氣) before diagnose the patients, the results are as follows. The observation of the body form is to determine prosperity and deficiency of each internal organ. It is necessary to distinguish Body form loss(形脫) and Body form fullness(形充). Fat man(肥人), Thin man(瘦人), Creamy man(膏人), Muscular man(肉人), Small Fat man(脂人) are discriminated by fat distribution, fat content, and muscle mass. The observation of the body form means the observation of structure disorder, color change, develop part at body, head and face. The observation of the body form that is to determine prosperity and deficiency of each internal organ is from the limited knowledge of the anatomy. The observation of face color is considered by blood perfusion, blood oxygenation and accumulation of carotinoid, bilirubin and change of melanin in the facial skin. The prosperity and the deficiency of energy flow is considered by symptom combined with growth (<40 years) and aging (>40 years). The prosperity of energy flow includes the anger, anxious emotion and the deficiency of energy flow includes the fear, depressive emotion. The breathing type is expiratory exhalation like asthma patients in the prosperity of energy flow. The deficiency of energy flow is weakness to overcome the disease. The prosperity and the deficiency of energy flow are considered by body metabolic ratios (Basal metabolic Rate: BMR, Resting metabolic rate: RMR, Physical activity ratios: PASs). Development of subcutaneous fat is good in the person of prosperous energy flow. The person of prosperous energy flow is hard to overcome to heat weather than cold weather. The person of deficiency of energy flow has tendencies of low blood pressure, insufficiency of blood flow in the peripheral and being shocked. The person of deficiency of energy flow has tendencies of chronic fatigue syndrome or automatic nerve disorder. If the patient who has deficiency of energy flow has severe weight loss should be checked for the presence of disease. The observation of small and large of bone is to check the development and disorder of bone growth and aging. The observation of thickness and weakness of muscle is to check the development of muscle, particularly biceps, gastrocnemius, and rectus abdominal muscle. The observation of thickness and weakness of skin is to check the ability of regulating body temperature by sweating.
This study investigated the effects of the nutrition education on body weight, visceral fat and diet quality in the postmenopausal women. The subjects (n = 101) were randomly divided into two groups: Nutrition education + Exercise (NEE) group (n = 51) and Exercise only (EO) group (n = 50). Nutrition education was consisted of counseling in portion control, food selection for low carbohydrate, high fiber food items and for the improvement in micronutrient intakes and diet quality. After 6 months, the reduction in the body weight and visceral fat area was significantly greater in the NEE than in the EO group. The NEE subjects were further divided into two groups according to the amount of visceral fat area reduction; high visceral fat area loss (HVL) group with a visceral fat area reduction 2.35% or greater and low visceral fat area loss (LVL) group with a reduction less than 2.35%. In the HVL group, the reduction in body weight, BMI, percent body fat, waist to hip ratio and visceral fat area was significantly greater than that in the LVL group. We observed a significant increase in the serum HDL-cholesterol level and a decrease in systolic blood pressure, fasting blood sucrose, total and LDL-cholesterol levels in the HVL group compared to the LVL group. The energyadjusted protein, fiber, calcium, vitamin $B_6$, vitamin C, vitamin E intakes were significantly increased in the HVL compared to LVL group. The index of nutritional quality (INQ) and mean adequacy ratio (MAR) were also increased in the HVL group compared to the LVL group. These results show that our nutrition education program was an effective intervention measure for the reduction of body weight and visceral fat, blood pressure, glucose and lipid levels in the blood and also for the improvement of nutrient intake and diet quality in postmenopausal women who are overweight.
The purpose of this study was to investigate the effect of carotid artery ultrasound Respectively. The carotid intima-media thickness is known to have a significant correlation with cardiovascular disease and cerebrovascular disease. We investigated the relationship between carotid intima - media thickness, body mass index, waist circumference, the blood lipid value, fasting blood glucose, glycated hemoglobin, and blood pressure using carotid artery ultrasound. The carotid artery ultrasound was considered to be abnormality of IMT thickness over 0.8 mm and the presence or absence of atherosclerotic plaque was evaluated. Serological tests were used to compare the geologic value, fasting blood glucose level, and glycated hemoglobin. As a result, waist circumference (=.022), low density cholesterol (=.004), fasting blood glucose level (.019), and glycemic index (.002) were analyzed as predictors of atherosclerosis. In the ROC curve analysis, sensitivity was 87.80% (95% CI: 73.8-95.9), specificity was 41.67% (95% CI: 30.2-53.9), sensitivity was 78.05% (95% CI: 62.4-89.4) in low density lipoprotein, Specificity was 50.00% (95% CI: 38.0-62.0), sensitivity was 73.11% (95% CI: 57.1-85.8), specificity was 61.11 (95% CI: 48.9-72.4) and sensitivity was 82.93%-91.8) and a specificity of 43.06% (31.4-55.3). In logistic regression analysis, the risk of atherosclerosis was 0.248 times at waist circumference (WC)> 76 cm, 3.475 times at low-density lipoprotein (LDL-C) ${\geq}124mg/dL$, 0.618 at HbA1c> 5.4% It appeared as a times. We suggest that prospective study of carotid artery ultrasound should be performed for the effective prevention of cardiovascular diseases.
Circulatory and respiratory activities were observed in men exposed to the environment of engine room of a cruising Republic of Korea Navy ship and compared to the control values obtained in an ordinary laboratory room on land. The environment of an engine room of cruising navy ship was presumed to be a multiple stress acting on men. The environment of the engine room included high temperature $(35-42^{\circ}C)$, low relative humidity (20-38% saturation), vibration (about 7 cycles per second), rolling and pitching of ship and noises. Sixteen men were divided into two groups consisted of each 8 subjects. Subjects of sea duty group had experience of continuous on board duty averaging 3.5 years. Men of land duty group had no experience of on board activity. On land observations were made on one day prior to the boarding and leaving the port and four days after landing. In between observations in the engine room were made on the first, 5 th, 9 th, 12 th, and 14 th day of on board activity. The whole experimental period lasted for 20 days. Measurements on circulatory and respiratory parameters were at standing resting state (after 30 minutes standing in the case of on land study and 15 minutes in engine room study) and within one minute after cessation of on the spot running of which rhythm was 30/min. and lasted for 5 minutes. Oxygen consumption and pulmonary function test were done in the period of two minutes from the 3rd to 5th minutes of running. The following results were obtained. 1. Body temperature showed no change regardless of group difference or on land or on board measurements. 2. Pulse rate increased markedly after boarding the ship id both groups. Pulse rate increased from the first day on board at rest and after exercise as compared to the on land control value. This increase in pulse rate was more marked after exercise. Sea duty group showed less increase in pulse rate at rest than the land duty group. Standing and resting pulse rate of sea duty group on lam was 81 and increased to 87 at the 5th day on board and remained smaller than the land duty group throughout the period on board. Control standing and resting pulse rate of land duty group on land was 76 and reached 89 at the 9th day on board and thereafter decreased a little. Pulse rate of land duty group at rest on board remained greater than that of sea duty group throughout the period on board. 3. Systolic blood pressure of sea duty group increased after boarding the ship and remained higher than the control value on land. In the land duty group, however, systolic blood pressure decreased during the period on board the ship. Diastolic blood pressure decreased in both groups. 4. Resting breathing rate of land duty group increased and remained higher than the control value on land. In sea duty group, however, resting breathing rate showed a transient increase on the 1st day on board and decreased thereafter to the control value on land and kept the same level throughout the period of cruise. Absolute value of breathing rate in the sea duty group was greater than the land duty group both at rest and after exercise. 5. There was a lowering of breathing efficiency in both groups. Thus, increases in tidal volume and minute ventilation volume and decreases in maximum breathing capacity, vital capacity, capacity ratio and air velocity Index were observed after boarding the ship. An increase in ventilation equivalent was also observed in both groups. The lowering of breathing efficiency was more marked in the land duty group than the sea duty group. 6. Energy expediture increased in both groups during their stay on the ship and was more marked in the sea duty group. 7, Lactate concentration in venous blood at rest and after exercise increased after boarding the ship and no group difference was observed.
Since binge eating is known to be related to increased risk of body weight fluctuations, it may be associated with increased health risks. This study was conducted to investigate the risks of binge eating on the cardiovascular system of female university students in Korea. Sixty-five female university students who were interested in a weight control program were recruited from a university campus. After personal interviews were conducted using a semi-structured questionnaire, 36 individuals were classified as binge eaters and 29 as non-binge eaters according to modified criteria of the proposed DSM-IV by the American Psychiatric Association(APA). All subjects participate in anthropometric and clinical measurements to evaluate the level of obesity and cardiovascular risks. Binge eating subjects showed no significant differences in obesity index compared to non-binge eating subjects. However, they had a higher level of low-density lipoprotein (LDL) cholesterol and a higher atherogenic index. They also showed close correlations with general obesity and cardiovascular risk factors. Body mass index(BMI) was the main explanatory index related to cardiovascular risk factors according to the stepwise regression analysis. Furthermore, obese binge subjects had higher levels than non-obese binge subjects or non-binge subjects for total cholesterol, LDL-cholesterol, triacylglycerols, atherogenic index, and systolic blood pressure. The findings strongly suggest that obese young women having binge eating episodes might display a greater risk for cardiovascular disease tan that shown for obese non-binge eating women.
The physiological and biochemical responses of healthy men and women to life stress were measured in order to temperature, blood pressure (BP), heart rate (HR) and galvanic skin response (GSR) were selected as physiological stress indices and salivary cortisol level was used as a biochemical stres biomarker. Twenty six (male 14 and female 13) colege students were participated in the experiment. Female showed the significant higher value of salivary cortisol level (p<0.01), diastolic BP (p<0.01), and HR (p<0.01) than male. The difference of skin temperature between forehead and fingertip correlated significantly with salivary cortisol level (p<0.01). The LF(low frequency)/HF(high frequency) ratio of HRV also correlated significantly with salivary cortisol level (p<0.01). However, BP, HR and GSR corelated insignificantly with salivary cortisol level. We suggest that LF/HF ratio of HRV and skin temperature may be good indices for the assessment of life stress, and may apply to measure the stress level of individual in real time.
Purpose: The purpose of this study was to examine the effects of a walking program for office workers in terms of social cognitive theory, walking activities and physiological indexes. Methods: A nonequivalent control group pretest-posttest design was used. The sample consisted of 50 office workers who were identified as having low levels of physical activity according to the International Physical Activity Questionnaire (IPAQ Research Committee, 2005). The participants were recruited from two companies in Seoul. Of the 50 participants, 26 were assigned to the non-equivalent experimental group and 24 to the control group. The walking program consisted of six didactic sessions via e-mail, two individual telecoaching sessions and three support group meetings over ten weeks. Data were analyzed using SPSS 17.0 program. Results: The non-equivalent experimental group reported significantly higher posttest scores in walking activities and adhering to the walking protocol than the control group. There were no differences in reported self-efficacy, outcome expectations, body mass index and blood pressure between the two groups. Conclusion: These findings indicate that a walking program based on social cognitive theory is effective in increasing physical activities for office workers.
Non-alcoholic fatty liver disease (NAFLD) is associated with various metabolic abnormalities, including central obesity, type 2 diabetes, dyslipidemia, and high blood pressure. This suggests that NAFLD may represent the hepatic manifestation of the metabolic syndrome. In this study, we investigated unfavorable effects NAFLD on components of metabolic syndrome in post-menopause women. Eight hundred sixty-nine postmenopausal women were recruited for this study. The diagnosis of fatty liver was based on the results of abdominal ultrasonography. Serum levels of fasting glucose, total cholesterol, triglyceride, and HDL-cholesterol were measured. The prevalence of component of metabolic syndrome such as hypertension, hyperglycemia, hypertriglyceridemia, and low-HDL-cholesterol was significantly higher in subjects with NAFLD as compared with those without NAFLD. The moderate to severe grade of NAFLD presented higher levels of serum fasting glucose, fasting insulin, HOMA-IR, total cholesterol, and triglycerides than the mild NAFLD and the normal group. In conclusion, metabolic syndrome risk was increased in post-menopause women with NAFLD as compared with those without NAFLD. The severity of NAFLD affected metabolic syndrome risk factors. The optimal strategy for the treatment of NAFLD is likely to include lifestyle modifications and therapy to improve insulin resistance.
