Purpose: The purpose of this study was to identify the effects of an aquatic exercise program on physical fitness, body composition, and gait characteristics using trunk and pelvic angle in women living in urban fringe area. Methods: An aquatic exercise program consists of exercise in a swimming pool and self-help group activity with 16 women living in urban fringe (mean age: 63 years) for 8 weeks (twice a week for 2 hours). Physical fitness, body composition, trunk and pelvic angle using 2D video motion analyzer, and a questionnaire including socio-demographic variables were measured from July to August, 2013. Data were analyzed using a paired t-test with the SPSS/WIN 18.0 program. Results: At the end of 8 weeks intervention, there were significant decreases on body weight (p=.025), body fat (p=.030) and BMI (p=.011). There were significant increases on muscle strength (p=.001) and flexibility (p=.015). Trunk angle was significantly improved, which means participants less moved their body from side to side when they walked (p=.001). Conclusion: From this results, the aquatic exercise program could be an effective nursing intervention to improve physical fitness, body composition, and gait ability for women living in urban fringe area.

The Objectives of this research is to determine the effect of aerobic exercise program on health status and physical fitness in patients after the stem cell transplantation. This research design is one-group pretest-post test design. Sixteen subjects were selected from one university hospital in Seoul for the study, they was carried out aerobic exercise three to five times a week for 12 weeks. The period of data collection was from February to July, 2000. The collected data was analysed by descriptive analysis, paired t-test, content analysis SAS program was used for the statistical analysis. The results are as follows : 1. There was a significant improvement in the Physical functioning, Vitality and Reported change (t=2.39, p=0.03; t=2.35, p=0.03; t=2.58, p=0.02) but no change was observed in the Role physical, General health perception, Bodily pain, Social functioning, Role emotional and Mental health. 2. There was a significant improvement in the physical fitness (higher VO2 max, t=2.43, p=0.02; lower systolic pressure, t=-4.09, p=0.001; lower diastolic pressure, t=-3.43, p=0.002; lower pulse rate, t=-3.43, p=0.004; higher muscle sustaining power, t=2.79, p=0.015; higher muscle power, t=5.18 p=0.000; higher power of beginning, t=5.55, p=0.001; higher the sense of equilibrium, t=3.57, p=0.003; higher Hemoglobin, t=5.92, p=0.000; higher Hematocrit, t=5.38, p=0.000). Therefore, this study will provide a theoretical back ground for patients after stem cell transplantation to understand the importance of physical exercise and maintain physical exercise; and for other researches to refer to the results for exercise protocol of rehabilitation program.

Purpose: The purpose of this study was to determine the effects of exercise using Thera Band on body compositions, blood pressure and physical fitness in the elderly women. Method: The study was designed as a nonequivalent control group pretest-posttest quasi-experimental study. Twenty four subjects were assigned for experimental group and twenty one subjects were assigned for control group. The experimental group participated in Thera Band exercise program consisting of 60 minutes per session, 3 times a week during the period of 12 weeks. The effects of the program were assessed using the instruments measuring the body compositions, blood pressure and physical fitness before and after applying the program. Data were collected between April and June in 2006, and analyzed by $x^2$-test, t-test, ANCOVA using a SPSS 11.5 program. Results: There were statistically significant in percent of body fat, muscle strength, muscle endurance, flexibility, and balance ability, but no significant differences were found in body weight, systolic pressure and diastolic pressure. Conclusion: Exercise using Thera Band can be an effective nursing intervention to improve percent of body fat, muscle strength, muscle endurance, flexibility and balance ability in the elderly women.

Purpose: The purpose of this study was to evaluate whether subjective symptoms, physical fitness, and emotional variables were improved after participating in a 6-week Tai Chi program in patients with rheumatoid arthritis. Methods: 23 rheumatoid arthritis patients participated in the Yang style Tai Chi for arthritis patients 90 minutes session conducted twice a week at the Arthritis Center of D University Hospital. The main outcome of current studies included self-reported scores of subjective symptoms(pain, sleep satisfaction, and fatigue), physical fitness tests, and depression (PHQ-9) and self-efficacy investigated with questionnaire before and after participating in Tai Chi. Results: After participating in Tai Chi, participants perceived lesser pain (t=2.61, p=.016) and fatigue (Z=-2.32, p=.020), and reported improved sleep satisfaction (t=-3.56, p=.002). In the physical fitness test, there were significant improvement in muscle strength (upper limb: t=-7.19, p<.001, lower limb: t=-4.86, p<.001), and balance (right t=-3.70, p=.001; left t=-2.30, p=.031). Depression (t=3.87, p=.001) and self-efficacy (Z=-3.44, p=.001) improved significantly after participating in Tai Chi. Conclusion: Tai Chi had beneficial effects on subjective symptoms and emotional variables as well as physical fitness. Therefore, the program could be recommended in the patients with rheumatoid arthritis.

The aim of this study was to investigate the effect of combine exercise on the fall injury related index and myokine in elderly women. Sarcopenia leads to a loss of strength, alter on to a decreased functional status, impaired mobility, a higher risk of falls, and eventually an increased risk of mortality. Aerobic exercise characterized by rhythmic and repetitive movements of large muscles, for sustained periods that depends primarily on the use of oxygen to meet energy demands through aerobic metabolism, and that is structured and intended to generate improvements in cardiopulmonary fitness, body composition, and cardiorespiratory health. Resistance training has performance in the elderly. As combined exercise therapy can be used to enhance muscle functions and cardiopulmonary functions, it is being highlighted as an effective health management methods for the aged. The myokine has been regarded an important factor of exercise how muscle communicate adipose tissue, bone and muscle to exert beneficial effects at the whole body level.

우리나라의 비만아동의 문제는 이미 그 규모와 분포 면에서 미국이나 유럽아동에 못지 않은 심각한 수준에 이르고 있다. 아동비만은 청소년기 비만, 장년기 비만으로 이어지며, 이는 곧 만성퇴행성 질환으로 이어지는 보건영양문제로서 그대로 방치할 것이 아니라 교육이나 건강행위실천을 통해 미리 적극적으로 예방해야 하는 문제이다. 또한 비만아동에게는 자신감 상실, 우울증, 부정적 자기 신체상 등과 같은 사회 정서적 문제들이 나타날 수 있으므로 몸과 마음이 모두 건강한 국민 체력향상 차원과 국가 경제의 안정을 도모하는 차원에서 비만 아동을 적극적으로 관리해야 할 필요가 있다.

최근 질적인 삶의 중요성과 건강에 대한 필요성이 향상되면서 운동의 중요성에 대한 국민의 인지도가 증가했다. 체력적인 효과 심리적인 효과 면역효과 등 운동이 주는 많은 긍정적인 영향들로 인해 최근 건강관리에 대해 사람들의 관심이 많이 증가했으나 자신에게 알맞는 운동 방법을 알지 못해 정작 운동을 실천하는 수는 그 수의 절반뿐이다. 따라서 개인의 신체 알맞는 운동을 추천해 줄 수 있는 추천 시스템이 필요하다. 본 논문에서는 신장, 몸무게, 나이, 주당 운동 횟수, 성별과 같은 개인화 요소를 이용한 협업 필터링과 k-nn 을 R 시스템을 사용하여 사용자 개인 맞춤형 운동 추천 시스템을 제안한다.

This study aimed to verify the reciprocal casual relationship between self-rated health status and depression in the elderly through longitudinal analysis. An autoregressive cross-lagged model was identified. This study analyzed 3,363 elderly people aged 65 or older using the 5th, 6th, and 7th wave data from Korean Longitudinal Study of Ageing(KLoSA). The results are as follows. First, self-rated health status had a positive(+) autoregressive effect. Second, depression had a positive(+) autoregressive effect. Third, self-rated health status had a negative(-) cross-lagged effect on depression, but depression was not a casual predictor of self-rated health status. Based on these findings, it was suggested that there is a need for systematic policies to improve basic fitness in the early stages of old age, as well as the need to expand health promotion programs and implement integrated depression management programs.
