Purpose: In this study, the following experiment was conducted to see how to apply the sprinter pattern in proprioceptive neuromuscular facilitation (PNF) and functional weight bearing exercise affected balance capabilities and weight bearing among chronic stroke patients. Methods: The subjects included 27 subjects who had been diagnosed with hemiplegia due to stroke. A total of 12 sessions was held, 3 sessions a week over 4 weeks, were provided to the groups. The control group received general rehabilitation program, and the experimental group performed sprinter pattern in PNF or functional weight bearing exercise. The weight bearing capability and static balance capability test was implemented by using Good-Balance System and Frailty and Injuries Cooperative Studies of Intervention Techniques, while the dynamic balance capability test was carried out by using Four Square Step Test and Timed "Up and Go". Results: The paretic/nonparetic side weight bearing by application of each exercise showed that there were no significant differences in variation among each groups on before exercise, after exercise, 2 weeks after exercise. Static balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Dynamic balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Conclusion: To put the results together, the application of sprinter pattern and functional weight bearing exercise was effective in improving static and dynamic balance capabilities. Therefore, these exercises are helpful to improve balance in patients with stroke.

This study was carried out to investigate the fast food consumption patterns classified by age in Busan. The survey was conducted from October 15 to November 15, 2006 by questionnaires and data analyzed by SPSS program. The results are summarized as follows: Forty one point five percent of the elementary group, 40.5% of the high school group, 24.1% of the 30's, 35.0% of the 40's and 18.1% of the 50's took fast foods over once a week. Seventy two point five percent of the elementary group, 61.5% of the high school group, 16.8% of the 30's group, 10.0% of the 40's, and 14.6% of the 50's preferred fast foods. There was a significant difference in the basis for selecting menus among the groups. The most important basis for selecting menus was 'price' in the elementary group and the high school group, but was 'preference' in the adult groups. As their age increased, they spend more money for fast food. Forty six percent of the elementary group and 49.5% of the high school group, 32.1% of the 30's, 36.5% of the 40's, 34.7% of the 50's thought that fast food can substitute for a meal. The age affected significantly the substitutability for the meal of the fast food (p < 0.001). In the high school group, the ratio of skipping breakfast is higher than in the other age groups. Dietary attitude has direct effects on the preference of the fast foods. Nutrition knowledge, degree of unbalanced diet and obesity rate have direct and indirect effects which were mediated by dietary attitude. Nutrition knowledge showed the greatest total causal effect in relation to the preference of the fast foods. Therefore, nutrition education for the subjects is needed to encourage them to choose more nutritious food and have healthier dietary pattern.

This study was conducted to investigate the relationship between drinking, smoking, meat intake, and exercise. The participants were 1,060 males and females who voluntarily responded to the survey by visiting the health promotion booth at the H Festival held in C city in 2014. Research data were collected in interview form using questionnaires on alcohol use, smoking, exercise, and meat intake. The data were analyzed by descriptive analysis, cross tabulation analysis, multinominal logistic regression after stratification of gender using the SPSS 24 program. The results of the study are as follows: Smokers had a significantly higher frequency of drinking ($x^2=163.33$, p<.001) than non-smokers. Meat intake was high when alcohol use was high ($x^2=35.13$, p<.001). The risk rates for smoking, meat consumption, and exercise related to alcohol use are as follows. The smoking was higher as the frequency of drinking increased. For men, smoking OR(odd ratio) was 6.26 (p=.001) and for women, smoking risk OR was 16.82 (p=.002). Meats intake showed a higher OR as the alcohol use increased. The OR of almost daily ingestion of meat at frequent drinking days was 4.40 (p=.002) for males and 4.52(p=.009) for females. As the frequency of drinking increased, the OR of days of exercise tended to decrease. In men, the OR was 0.36 (p=.003), the lowest in the probability of exercising more than 5 days when drinking high. In the case of women drinking less than once a week, the OR was 0.43 (p=.027), which was the lowest for exercise for 5 days or more. In conclusion, the higher the frequency of drinking, the higher the smoking and meat intake, and the less exercise. If drinking, smoking, and meat intake are high but there is a lack of exercise, a chronic disease can occur and cause premature death unless there is a change in the new health behavior. The results of this study suggest researches to understand the motives related to alcohol abstinence, smoking cessation, dietary control and exercise, and to develop programs.

Background : Pulmonary rehabilitation, called pulmonary rehab or PR, is a broad program that helps improve the well-being of people who have chronic (ongoing) breathing problems. Purpose : The purpose of this study was to demonstrate the effects of the upper abdominal exercise and balloon blow-up on the abdominal muscle strength and Respiratory ability for 20's adults. Method : Recruited Subjects were healthy students attending H university. Twenty-one subjects who agreed to participate in this study were randomly assigned to 3 groups; I group applied upper abdominal exercise, IIgroup applied balloon blow-up, III group applied both upper abdominal exercises and balloon blow-ups. Upper abdominal muscle exercises was applied supine position and $30^{\circ}{\sim}40^{\circ}$ in the upper body lift braced for about 3 seconds, and balloon blow-ups was performed 10 times a day. The exercise programs were performed three times a week for 5 weeks. Results: After 5 weeks of exercises, all three groups were comparable with abdominal muscle strength and respiratory ability. Subjects in upper abdominal exercise group, balloon blow-ups group, and upper abdominal exercises and balloon blow-ups group had significantly increased the average of abdominal muscle strength(p<.05) The statistical comparison among the groups indicated that there was a signigicant increase in respiratory ability. In comparison of abdominal muscle strength and respiratory ability, there were no significant differences among 3 groups. Conclusions: These findings suggest that upper abdominal exercises and balloon blow-ups may have a significant impact in abdominal muscle strength and respiratory ability.

This study was conducted to compare the perception and fast food usage patterns of adults classified by age in Busan. The survey was conducted from April 15 to June 15, 2017 by questionnaires and the data were analyzed using SPSS 24.0 Overall, 74.1%, 58.1%, 40.7%, 20.3%, 29.7% and 17.9% of individuals in their 20s, 30s, 40s, 50s, 60s and 70s, respectively, consumed fast foods more than once a week. Additionally, 66.0%, 52.5%, 25.7%, 16.0%, 22.9% and 11.7% of individuals in their 20s, 30s, 40s, 50s, 60s, and 70s, respectively, preferred fast foods. There was a significant difference in the basis for choosing menu among the groups, with 'preference' and 'price' being most important to those in their 20s and 30s, on the other hand 'preference' and 'companion' being most important to members of other age groups. As their age increased, individuals spent less money on fast food. Overall, 81.5%, 59.9%, 50.0%, 40.1%, 46.3%, and 28.4% of individuals in their 20s, 30s, 40s, 50s, 60s and 70s thought that fast food was a suitable substitute for a meal. Age affected the substitutability of fast food for a meal (P<0.001). Additionally, the ratio of individuals in their 20s and 30s that skipped breakfast was higher than in other age groups. In addition, age showed a significant positive correlation with obesity and dietary attitude, whereas it showed a negative correlation with nutrition knowledge, use frequency, perception degree and preference. Nutrition knowledge and dietary attitude showed no relationship with preference. These results imply that a nutrition education program should be developed and conducted to induce subjects to manage their dietary habit and develop healthier dietary patterns.

The study was performed to investigate the relationship of regular exercise to body composition and nutrient intakes of male college students by comparing anthropometric measurements and one-day dietary intakes by 24-hour recall of physical education (PE) majors and non-major male college students. The subjects were 253 students residing in the Gyeonggi area. Only 64.1% and 32.1% of PE majors and non-major students exercised over 4 times a week and PE major students did stronger exercise than the non-major students did. Mean BMI and WHR (Waist Hip Ratio) of the two groups were not different. But percentages of body fat and lean body mass in PE major students were lower and higher, respectively, than those of non-major students. PE major students consumed significantly more energy and other nutrients except iron, niacin, vitamin C, and vitamin E than non-major students. Nutrients consumed less than KRDA was calcium in PE major students and energy, calcium, zinc, vitamin $B_{12}$, folate, and vitamin C in non-major students. Mean adequacy ratio (MAR) of PE major students (1.00) was significantly higher than that of non-major students (0.94). Index of Nutritional Quality (INQ) of all nutrients except vitamin A of PE major students was also significantly higher than that of non-major students. Nutrients below 1.00 in INQ of both groups were calcium, zinc, vitamin B2, and folate. Our data supports that regular exercise may positively influence on body composition and increase diet quality in male college students. Therefore, an educational program focused on regular exercise along with proper dietary behavior would be needed.

Objectives: The purpose of this study was to examine the influence of cooperative learning on the learning attitude and self-directed learning capability of learners. Methods: The subjects were 50 sophomores enrolled in cooperative learning for 12-week period from March to June, 2014. A self-reported questionnaire was completed by the subjects. The instruments were 16 questions of learning attitude, 32 questions of self-directed learning, academic achievement, and 12 questions of satisfaction with instruction by Likert 5 scale. Cronbach's alpha was 0.84 in the previous study and 0.78 in this study. Self-directed learning was modified by Yoo and Cheong. Cronbach's alpha of self-directed learning was 0.86 in this study. Academic achievement was assessed by before and after the cooperative learning class. Cronbach's alpha was 0.95 in this study. Their learning attitude and self-directed learning capability were evaluated before and after the cooperative learning, and their satisfaction with the instruction and academic achievement were assessed by the written examination. Results: The score of learning attitude increased from 2.89 in the pretest to 3.38 in the posttest. The self-directed learning of the students increased from 2.98 in the pretest to 3.48 in the posttest. The academic achievement of students also increased from 82.0 in the pretest to 85.2 in the posttest. The satisfaction with instruction was 4.24 of Likert 5 scale. There were significant differences in satisfaction with instruction, cooperative learning and academic achievement. Conclusions: It is important to develop the cooperative learning program linked to self-directed learning for the dental hygiene students continuously. This study will provide the basic data and information for the development of new teaching methods for the dental hygiene.

Purpose: Previous studies have reported that action observation training has beneficial effects on enhancing the motor task, such as balance and gait functions. On the other hand, there have been few studies combined with action observation training and auditory feedback. The purpose of this study was to determine the effects of action observation training with auditory feedback on the gait function in stroke patients with hemiparesis Methods: A total of 24 inpatients with post-stroke hemiparesis were assigned randomly to either an experimental group 1 (EG 1, n=8), experiment group 2 (EG 2, n=8), control group (CG, n=8, EG 1). The EG 2 and CG watched video clip demonstrating three functional walking tasks with auditory feedback, without auditory feedback, and showing a landscape image, respectively. The exercise program consisted of 30 minutes, five times a week, for four weeks. The participants were measured to 10MWT (10 m walk test), 6MWT (6 minutes walking distance test), TUG (timed up and go test), DGI (dynamic gait index), time and steps of F8WT (figure-of-8 walk test). Results: In the intra-group comparison after the intervention, EG 1 and EG 2 showed a significantly different gait function (10MWT, 6MWT, DGI, TUG, F8WT) (p<0.05). In the inter-group comparison after intervention, EG 1 showed significant improvements in the entire gait parameters and EG 2 only showed significant improvement in DGI and TUG compared to CG (p<0.05). Conclusion: These findings show that action observation training with auditory feedback may be used beneficially for improving the gait function of stroke patients with hemiparesis.

Background : The aims of medical education have recently been changing in Korea, which has been accompanied by efforts to modify the rotating clerkship courses, improve the quality of clinical education, and make global doctors. We report the experiences of medical students going through an international elective clerkship for during past two years. Materials and Methods: Third year medical students could apply to the international elective clerkship course during a 4 week period alter their third-year rotating clerkship at a university hospital. This was done twice - in 2008 and in 2009. Applicant students were allowed to select hospitals anywhere in the world. We analyzed their choices including data on nation, state or city, hospital or institute, contacted hospitals by medical college, differences of two years, etc. Results : Twelve students (10.9%) of a total of 75 third-year students applied to 3 nations and 4 hospitals in 2008. Nine students applied to the Tampa General Hospital at the University of South Florida (USF) in the USA, which was arranged by their medical college. In 2009, a total of five (4.2%) of 77 students applied to 2 nations and 3 hospitals, including three at the University of South Florida, one in another city in the USA, and one in another nation because of the increased financial burden due to a higher exchange rate. Conclusion: Medical students started their first international elective clerkship courses during the past two years. Experiences were interesting and meaningful to the students and the medical college. Greater effort and support to developing a new paradigm and to enlarge the scope of the program for making global doctors are required in the future.
