The purpose of this study was to examine the influence of total knee replacement to arthritis patients in pain intensity and functional impairment. For this study, over 50-year-old 30 patients who had osteoarthritis and 69 patients who got total knee replacement at the one of the departments of orthopedics in Daegu were interviewed from June, 2002 to March, 2003. The results of this study were as follows : First, pain intensity was decreased to experimental group after operation than control group(P<.01) And the presence of crepitation was also decreased to them(P<.05). On the other hand there's no significant difference was noted in the presence of stiffness, degree of flexion contracture and extension contracture between two groups. Second, over 91 days group after operation and visitor's group of physiotherapy unit were better than others in Level of knee function(P<.01). Third, over 91 days group after operation and visitor's group of physiotherapy unit were higher than others in Barthel Index of knee function(P<.01). Forth, over 91 days group after operation and visitor's group of physiotherapy unit were higher than others in Level of IADL(P<.05). Fifth, over 91 days group after operation and visitor‘s group of physiotherapy unit were higher than others in Katz Index of knee function(P<.01). Sixth, although Old Ages' Activity Index seemed to get better as time goes by, there's no statistical difference. Seventh, over 91 days group after operation and visitor's group of physiotherapy unit were higher than admission group and under 30 days group after operation in Social Activity Index(P<.05). Eighth, the function of the knee was connected with the abilities in the activity of the old and the social skill. The Barthel index was connected with the function of the knee joint and the activities of the old and Katz index. IADL function was connected with the activities of the old and the social activity. The Katz index was connected with the Barthel index. The activity of the old was connected with the Barthel index, the functional score of the knee joint andthe IADL score. The ability of social skill was connected with the activity of the old, IADL score and the function of the knee.

This study aimed to compare movement patterns of shoulder joints between the right and left symmetry in stroke patients and control subjects. This study proposes use of the voluntary response index (VRI) calculated from quantitative analysis of surface electromyographic (sEMG) and motion data recorded during voluntary movement as a feeding task. The VRI is comprised of two numeric values, one derived from the total muscle activity recorded for the voluntary motor task (magnitude), and the other from the sEMG distribution across the recorded muscles with the similarity index (SI). Five stroke patients and five age-matched healthy controls were recruited. Feeding motion was performed using the provided spoon five times with rests taken on a chair in between tasks. EMG data were digitized and analyzed on the basis of the root mean square (RMS) envelope of activity. The average amplitude of responses was calculated. Responsiveness and clinically meaningful levels of discrimination between stroke patients and control for EMG magnitude and SI were determined. The similarity index of the results from two successive examinations of both sides apart for stroke patients and control subjects were .86 and .95 in motion analysis and .84 and .99 in electromyographic analysis. The SI of sEMG data and motion data was significantly correlated in stroke patients. The data suggest that SI is a sensitive program for comparing and analyzing the symmetry of muscle activity and motion in both sides. This analysis method has a clinical value in grading muscular activity and movement impairment after brain injury.

There are a few studies that reported the association of sleep duration with calorie intake and energy expenditure. Using cross-sectional data from a population-based prospective study, we evaluated the association of sleep duration with indicators of obesity including body mass index and waist circumference, calorie intake and its proportion of macronutrients, and physical activity. The study subjects were 4,226 male and female adults, who were aged 40 to 69 years and were free of diagnosed cardiovascular disease, diabetes mellitus, and dyslipidemia at baseline. Robust regression analysis was used to analyze associations. The study found that sleep duration is inversely associated with waist circumference, calorie intake, and percent of calories from fat intake and is positively associated with percent of calories from carbohydrate intake and physical activity. The inverse association between sleep duration and waist circumference was stronger among men than among women. The inverse association between sleep duration and calorie intake was stronger among women than among men and such association was also stronger among obese persons than those with a normal body mass index. The positive association between sleep duration and physical activity was strongly demonstrated regardless of sex or obesity. Physical activity is positively associated with sleep duration independent of potential confounding factors including age, sex, income, occupation, marital status, education, smoking status, waist circumference, calorie and macronutrient intake, and alcohol intake.

Purpose: The purpose of this study was to investigate the state and factors associated with level of physical activity and exercise in adolescents. Method: The subjects in this study included 528 adolescents registered at two junior high schools and two senior high schools in J City. The data were collected between October 20 and 30, 2006. Result: The study results showed that 23.8% of the adolescents engaged in vigorous activities for at least 20 minutes, three times a week, while 3.8% of the adolescents participated in moderate activities for at least 30 minutes, five times a week. The subjective level of health was determined to be $3.51\pm.91$ points on a 5-point scale. The level of stress was $2.58\pm.83$ points on a 4-point scale. The obesity index was $4.26\pm20.84$ points. Significant correlations were found between the subjective level of health and level of stress (r=-.201, p=.000), the subjective level of health and the obesity index (r=-.135, p=.004), and between the level of stress and the obesity index (r=.107, p=.024). Conclusion: These results showed that developing a health promotion program that includes an exercise program specific to gender and level of education, individualized strategies of stress control and optimal weight control is required.

Objectives: The purpose of this study is to recognize change of menstrual patterns and dysmenorrhea according to obesity indices and physical activity in female college students. Methods: From March 22nd to May 14th, 2010 we researched 1,407 women students at OO College by questionnaires to investigate their menstruation, dysmenorrhea, obesity and physical activity. Results: 1. Triglyceride(TG) was decreased statistically in the regular group of menstrual cycle as compared with the irregular group. 2. Menstrual duration was not associated with obesity indices. 3. Higher BMI was associated with more menstrual amount. 4. Dysmenorrhea was increased with decreasing BMI. 5. Neither menstrual patterns nor dysmenorrhea were associated with physical activity, but dysmenorrhea was decreased in minimally active group. Conclusion: This study showed the significant effect of menstruation and dysmenorrhea on obesity indices and physical activity. Obesity is related to menstruation and dysmenorrhea, but physical activity isn't related to them.

Purpose: This study compared the body composition and health conservation of low and high physical activity groups in professional retired elderly. Methods: The participants were 132 professional retired elders using a university of education for the elderly and senior welfare centers in D and K city. Data were collected through interviews from November to December in 2015. The body composition was measured using an Inbody 230 and the health conservation was measured using Sung's (2005) Health Conservation Scale. The low and high physical activity groups were divided by CHAMPS (The Community Healthy Activities Model Program for Seniors Questionnaire). The collected data were analyzed using a $x^2$ test, independentt-test, andbinary logistic regression using the SPSS/WIN 20.0 program. Results: The body composition (body mass index, body fat percentage, and fitness score) and health conservation score were higher in the high physical activity group than in the low physical activity group. The result shows that the body weight (OR=10.62) is the highest risk factor influencing the physical activity in professional career-retired elders. Conclusion: These results suggest that to induce physical activity level among professional retired elders, nursing interventions are needed to increase the health conservation and body composition, particularly in controlling the body weight.

This study investigated the effect of physical training and oxidative stress on the anti oxidative activity and on plasma lipid profile. Forty eight rats were given either a physical training or no training for 4 weeks and were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The antioxidative activity was evaluated with the activities of catalase in plasma and superoxide dismutase (SOD), the ratio of reduced glutathione/ oxidized glutathione (GSH/GSSG) and the level of malondialdehyde (MDA) in liver. The plasma concentrations of triglyceride (TG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C)) were also compared. Compared to those of non-training group. catalase activities of training group were lower before exercise but higher during and after exercise. SOD activities were higher regardless of exercise. GSH/GSSG ratio was higher before exercise but was not significantly different during exercise and even lower after exercise. There were no differences between non-training group and training group in MDA levels regardless of exercise. Compared to those of non-training group, atherosclerotic index of training group was lower after exercise and there were no significant differences before and during exercise. There were no differences between non-training group and training group in HDL-C regardless of exercise. These results suggest that moderate physical training can activate antioxidant defenses and decrease the atherosclerotic index and this beneficial effect is evident under exercise-induced oxidative stress.

The purpose of this study was to analyze characteristics of the obese children in depth and provide basic information for a comprehensive educational program for the obese children. Physical and biochemical characteristics, nutrient intake, and self-esteem, etc. of 16 obese elementary school children (OC) and 14 normal weight elementary school children (NWC) were examined. Self-esteem was measured using Likert-type scales with description. Plasma levels of total cholesterol, LDL-cholesterol, and glucose of OC were higher than those of NWC. Dietary intake with a lunch provided more energy and vitamin B1 in OC than in NWC. Physical appearance and athletic competence among self-esteem in OC were lower than in NWC. However, there was no significant difference in physical activity between OC and NWC. In OC, atherogenic index was positively related with waist circumference, obesity index and BMI while athletic competence self-esteem was negatively related with them. It is recommended that the children should receive the comprehensive educational program for improving children' dietary behavior and their self-esteem.

Osteoporosis is characterized by low bone mass and the microarchitectural deterioration of bone tissue with a consequent increase in bone fragility and susceptibility to fracture. It has been suggested that speed of sound (SOS) and broadband ultrasound attenuation (BUA) of quantitative ultrasound sonography (QUS) may provide information about not only bone density but also the microarchitecture and elastic properties of bone. Physical inactivity reduced mechanical usage and it made process to the bone changes. This study aimed to association between the physical activity and the QUS parameters in 1305 (593 men, 712 women) aged 20 years over in a rural population. Two QUS parameters, BUA (p=.23) and SOS(p=.73) were measured at the right calcaneus of postmenopausal women, no significant associations were observed between sports index and SOS and BUA. These results suggest that work, non-sports leisure physical activity (p<.01) have a significant influence on QUS parameters in a rural population. Physical activity are meaningful predictor of QUS parameters of the calcaneus in a rural population.
