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 was conducted to examine the effects of low-density exercise on physical and psychological function of the frail elderly. The research design was nonequivalent control group pretest-posttest design. Data were analyzed using descriptive statistics, x2-test, Mann-Whitney U test and Cronbach's ${\alpha}$ with SPSS/Win 17.0 program. There was a significant improvement in Lt. Grip strength(U=56.00, p<.000), Rt. Grip strength(U=40.00, p<.000), TUG(U=95.00, p<.022), Depression(U=94.00, p<.011) in the experimental group compared to the control group. The low-density exercise program showed the effects to improve the physical and psychological functions of the frail elderly. In recommendation, this exercise program could be utilized as a health promoting program for the frail elderly.

Background: Falls are among the most common and serious health problems of older people. The psychological symptoms of falling have received relatively little attention compared to physical problems. Objective: The purpose of this study is to test a model to explain the factors that influence fear of falling among older adults living in a continuing care retirement community (CCRC) in Baltimore city, United States. Methods: A secondary analysis was conducted using data obtained from a Health Promotion Survey done on 149 older adults living in a CCRC. Data was originally obtained during face to face interviews with each participant. Descriptive statistics and bivariate correlations were used to describe the sample and evaluate simple correlations. A path analysis was done using the AMOS 4.0 statistical program. Results: Of the 49 hypothesized paths, 13 were statistically significant, and the model accounted for 22% of the variance in fear of falling among the elderly. There was support for the fit of the model to the data with a nonsignificant chi square at 0.478 (df=2, p=0.79), and the ratio of chi-square to degrees of freedom was 0.24, a CFI of 0.99 and RMSEA of 0.00. In particular, gender, a history of falling, and exercise were significant predictors of fear of falling. Conclusions/Implications: As anticipated, exercise is an important factor to prevent fear of falling. As a modifiable variable, self-efficacy and outcome expectation indirectly influence fear of falling through exercise.

Size, velocity, and time equivalence are mechanisms that allow us to perceive objects in three-dimensional space consistently, despite errors on the two-dimensional retinal image. These mechanisms work on common cues, suggesting that the perception of motion distance, motion speed, and motion time may share common processing. This can lead to the hypothesis that, despite the spatial nature of visual stimuli distorting temporal perception, the perception of motion speed and the perception of motion duration will tend to oppose each other, as observed for objects moving in the environment. To test this hypothesis, the present study measured perceived speed using Müller-Lyer illusion stimulus to determine the relationship between the time-perception consequences of motion stimuli observed in previous studies and the speed perception measured in the present study. Experiment 1 manipulated the perceived motion trajectory while controlling for the retinal motion trajectory, and Experiment 2 manipulated the retinal motion trajectory while controlling for the perceived motion trajectory. The result is that the speed of the inward stimulus, which is perceived to be shorter, is estimated to be higher than that of the outward stimulus, which is perceived to be longer than the actual distance traveled. Taken together with previous time perception findings, namely that time perception is expanded for outward stimuli and contracted for inward stimuli, this suggests that when the perceived trajectory of a stimulus manipulated by the Müller-Lyer illusion is controlled for, perceived speed decreases with increasing duration and increases with decreasing duration when the perceived distance of the stimulus is constant. This relationship suggests that the relationship between time and speed perceived by spatial cues corresponds to the properties of objects moving in the environment, i.e, an increase in time decreases speed and a decrease in time increases speed when distance remains the same.

The purpose of this study was to examine how the fitness participation was influenced on exercise enthusiasm, exercise commitment and exercise satisfaction by female fitness participants, Subjects were selected among the female fitness center users living in Sunchon, Yeosu, Gwangyang. A total of 223 questionnaires were used in the actual analysis via convenience sampling method out of 250 questionnaires. Data analysis wad processed by SPSS 25.0 program with frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis and multiple regression analysis and the following results were made. First, as a result of analyzing the effects of exercise enthusiasm on exercise commitment, it was found that harmony enthusiasm had positive (+) influence on cognitive commitment and behavioral commitment. Second, as a result of analyzing the effects of exercise enthusiasm on exercise satisfaction, it was found that harmony enthusiasm had positive (+) influence on exercise ability improvement, social relationship promotion and psychological benefits, and harmony enthusiasm and compulsive enthusiasm had positive (+) influence on physical function improvement. Third, as a result of analyzing the effects of commitment on exercise satisfaction, it was found that behavioral commitment had positive (+) influence on exercise ability improvement, physical function improvement and social relationship promotion and harmony enthusiasm and compulsive enthusiasm had positive(+) influence on psychological benefits.

This study set out to investigate structural relations among positive thinking, identity, sports happiness perception, and athletic burnout and analyze the mediating effects of identity and sports happiness perception on relations between positive thinking and athletic burnout in order to understand the psychological process of athletic burnout experienced by adolescent players. For these purposes, the study applied the convenience sampling method to male and female players at physical education and general middle and high schools around the nation and used total 306 questionnaires as final valid samples. Collected data was tested for the fitness of an overall model with the SPSS 22.0 and AMOS 22.0 programs. Then the hypotheses were tested. The findings were as follows: first, subjective satisfaction and pursuit of a goal in the category of positive thinking had significant effects on athletic identity; second, subjective satisfaction and pursuit of a goal in the category of positive thinking had no impacts on sports happiness perception; third, the athletic identity of adolescent players had positive impacts on their sports happiness perception and negative ones on their athletic burnout; fourth, the sports happiness perception of adolescent players had negative effects on their athletic burnout; and finally, athletic identity had mediating roles on relations between pursuit of a goal of positive thinking and sports happiness perception and on relations between pursuit of a goal of positive thinking and athletic burnout.
