  • The purpose of this study is to understand the effect of violence in sports on intention to sport continuance among female athletes and to analysis the mediating effect of depression and the difference groups according to help-seeking. In order to accomplish these purposes, this study surveyed from September to October in 2010. The final subjects in the analysis were 345 female athletes who are belong to school athletic team, professional team, business team, and national team. The data were analyzed with SPSS 18.0 and AMOS 10.0 for conducting multiple group analysis. The main results of this study are as follows; First, those who were suffered by emotional violence were 62.4%; those who are damaged by physical violence were 28.6% among the participants in this study. In case of intention to sport continuance, when measured by a rule of five, was average 3.15. 29.9% of the female athletes scored above the standard of depression. Second, depression turned out to have a partial mediating effect within the relationship where violence in sports has effect on intention to sport continuance. Third, between experimental and non-experimental group on help-seeking among female athletes, there was a statistically significant difference in the structural relationship. This means that help-seeking has moderating effect within the path of violence in sports affecting depression. Based on the results, this study suggested that there is a strong need for intervention for the both prevention and cure of the sports violence. It is necessary to develop preventive programs and coping strategies on female athletes' depression and intention to sport continuance.

  • It is important to exercise in the correct posture in order to increase the exercise effect of the core exercise. This paper introduces a system that can train an exercise posture by providing feedback so that a user who performs core exercise in a virtual reality environment can take an accurate posture. It targeted three core movement postures, such as squat, lunge, and bridge, and provides visual feedback and haptic feedback to the user to take an accurate posture. The reference posture is generated by adjusting the expert's posture to the user's body length, and the accuracy of the exercise posture is calculated by comparing the user's posture with the reference posture. The effectiveness of the feedback was verified through user experiments, and the training effects according to the design of the feedback were compared.

  • Obesity is frequently associated with metabolic disease. This study showed whether fenofibrate, a hypolipidemic agent, swimming and swimming combined with fenofibrate (: combination) regulate obesity, and whether combination is more effective than fenofibrate on regulation of obesity in high-fat diet-fed mice for 8 weeks. Both fenofibrate and swimming decreased obesity-associated factors such as body weight, adipose tissue mass, serum lipid levels and adipoctye size, compared with control mice. When mice were concomitantly treated with fenofibrate and swimming, combination reduced further the inhibitory effects on obesity-associated factors, compared with fenofibrate. Both fenofibrate, swimming and combination decreased serum glucose levels, compared with control mice. The evidence is presented herein that combination were effective to control obesity and serum glucose levels, suggesting that swimming combined with fenofibrate might contribute to inhibition of high-fat diet fed-induced metabolic syndrome.

  • The stationary image appears to move after we view a moving stimulus for a long time. The motion aftereffect(MAE) can spread to an adjacent region if there is no contrast discontinuity between two regions. In this study, it is investigated whether a phenomenon of MAE spreading to an adjacent non adapting area is affected by the depth discontinuity defined by binocular disparity. In the first experiment a disparity defined slanted pattern was presented in an unadapted region, and in the second experiment, a disparity defined pattern with a different depth was presented on the fronto-parallel plane. Although MAE duration in the condition with slanted pattern was not different from that in the non-slanted pattern condition, MAE durations in the pattern presented on pronto-parallel plane was vividly reduced, but not completely disappeared. These results suggest that a phenomenon of MAE spreading might be affected by depth discontinuity, and could be occurred after binocular information converges.

  • The use of computers has increased greatly, and services have been developed very much for the convenience of users. As the use of computers increases, human activity has declined, and symptoms of deterioration in health are increasing. As the time to sit and live increased, humans are more exposed to diseases of low back pain, and low back pain includes pain related to the lower back centering on the herniated disc. Most of the back pain is caused by abnormalities in the muscles and ligaments that support the spine and trunk. In this paper, we present an overall design for developing an app that can obtain lumbar exercise effects to reduce low back pain or help treatment. In order to use this effectively, we propose a plan to obtain lumbar exercise effect, and aim to present an app design that can help effectively treat low back pain by using graphic-based guidance points.

  • The purposes of this study were to observe the effects of the exercise programs which have different order of walking and resistance exercises on the composition of the abdominal fat and the blood lipid profiles of the obese college women and to provide basic materials for the development of more effective and more efficient exercise program in order to reduce and prevent obesity. Classification of group, "A" group(resistance exercise after aerobic exercise) is a group of 12 people, "B" group(resistance exercise after aerobic exercise) is a group of 12 people. To determine the abdominal fat, intestine fat area, subcutaneous fat area, ratio of intestine fat area/subcutaneous fat area were analyzed, while for the blood lipid profiles, total cholesterol, triglyceride, high density lipid protein, and low density lipid protein were analyzed. First, there was statistically significant difference in the interaction in the abdomen subcutaneous fat. In the post analysis, the Resistance first group showed significantly more reduction to confirm that there was difference according to the order of the exercises. Second, there was statistically significant difference in the interaction effects in the factor of triglyceride. In the post analysis, the Resistance first group only showed significant reduction in the triglyceride to confirm that resistance exercise followed by aerobics would be better for the reduction of the triglyceride.

  • To investigate the effect of high-intensity interval training (HIIT) on the outcomes of cardiac rehabilitation(CR) in elderly and younger patients with myocardial infarction(MI). Of the MI patients who received hospital-based CR from 2015 to 2017, we retrospectively reviewed the medical records of the patients who continued follow-up through the outpatient clinic. A total of 39 patients (20 elderly patients (${\geq}60year$($64.1{\pm}3.6$)) and 19 younger patients (< 60 year($55.6{\pm}2.3$)) was included in this study. The HIIT program was composed of 10 minutes of warm-up, 30 minutes of interval aerobic exercise, and 10 minutes of cool down. The aerobic exercise based on their initial exercise tolerance test outcome consisted of 3-minute usual intensity phase (60-70% of heart rate/VO2 reserve) and 4-minute of high-intensity phase (70-90% of heart rate/VO2 reserve). Exercise capacity was measured by exercise tests before and after hospital- based CR. Before CR, elderly group had a significantly lower exercise capacity in Exercise time, peak VO2, METs, Anaerobic threshold, VEmax, 02pulse than younger group. Both group showed similar improvement of cardiopulmonary exercise capacity after CR. And HIIT is safe and effective in elderly patients. It is considered necessary to further expansion for the participation of high intensity interval training in elderly patients.

  • This study investigated Greene and Corwder(1984)'s modified PAS model, according to which, in a short-term memory recall task, the recency and suffix effects existing in auditory and visual conditions are mediated by the same mechanisms. It also investigated whether the auditory information and mouthed information are encoded by the same codes. Though the experimental manipulation of the phonological nature, the presence of differential recall effect of consonant-and vowel-varied stimuli in auditory and mouthing conditions which has been supposed to interact with the recency and suffix effects, was investigated. The result shows that differential recall effect between consonant and vowel exists only in the auditory condition, but not in the mouthing condition. Thus, this result supported Turner.
