The purpose of this study was to investigate the balancing training effect on weight bearing ratio and postural sway on the unstable surface for the CVA patients with balance disability. The inclusion criteria were walking independently 20m distances. Eighteen subjects, 4 with right and 14 with left hemiplegic patients were participated in this study. The range of age was from 35 to 75 and the duration from onset time was from 1 to 38 months. The intervention program including balancing training that they were introduced for 10 minutes every other day during 12 weeks to experimental group, and general therapeutic exercise to control group. The result of this study were as following; 1. The balancing training on the unstable surface showed that the postural sway of left/right distribution would appear more effective on sitting with eyes opened. 2. The balancing training on the unstable surface showed that the postural sway of forward/rear distribution, left/right distribution and distance would appear more effective on standing with eyes opened. 3. The balancing training on unstable surface would increase more effective on the weight-bearing ratio of left/right difference and frequency. 4. The balancing training on unstable surface was statistical significant on the postural sway of left/right distribution and area in experimental group. and it was statistical significant on the postural sway of forward/rear distribution, left/right distribution and distance in control group, too.

With regard to the culture in cities this study aims to essential understanding and systematic approach to the culture. The "2011 Seoul Survey"report has been used to find out causality among the related variables. In the first place 'satisfaction of cultural condition' was operationally selected as a dependent variable for regression. For the purpose of controlling confounding factors for ceteris paribus effect correlation analysis was done between the dependent variable and all other variables respectively, which resulted in two groups of variables: group (1) - 6 variables of very significant correlations(p-value<0.01) and (2) - the other 6 variables of significant correlations(p-value<0.05). Then hierarchical regression was adopted to these 2 groups to analyse $R^2$ increment, statistical significance of independent variables, and multicollinearity(VIF; variance inflation factor). At last a regression model specified by group (1) as independent variables(they are 'social trust', 'satisfaction of walking condition', 'happiness index', 'preparation against old age', 'satisfaction of traffic condition' and 'hours for internet') shows that only 'social trust' variable has statistically significant and substantially strong effect on 'satisfaction of cultural condition.' This finding should be accepted on the following understanding; (1) urban culture has a collective attribute formed between people and society, (2) culture is somewhat telling and hearing stories and the confidence between tellers and hearers is essential in the mutual response and (3) stimulus is received by relationship in company with sense, emotion, thinking and action. In spite of restrictive external validity this finding can be used as a direction for promoting culture and a basis for related policy choice in cities.

Background: South Korea is one of fastest aging countries in the world. Poor balance and falls of the elderly are main health issues. Objects: The goal of this study was to understand the association between the socioeconomical factors and the standing balance of elderly living in the rural and urban area. Methods: One hundred sixty-six elderly participants who were older than 65 and were able to walk without an assistive device were recruited in the city of Gwangju and in the rural area of Jeonnam, South Korea. All participants performed the static and dynamic standing balance tests. Static standing balance was measured with chronometer in seconds while standing on one leg. Dynamic balance was tested with the timed up and go test (TUG), measured in seconds while getting up from a chair and walking 3 meters and back to sit. The static and dynamic standing balance was analyzed using analysis of variance and the Fisher's Least Significant Difference post hoc test. Results: Male participants from both areas had no difference in one leg standing and TUG. The female elderly living in rural area took shorter in TUG than females living in urban area. Age decreased the one leg standing time in both areas while did not affect the TUG significantly. As the monthly income increased, both of one leg standing and TUG increased in urban area, while the medium monthly income showed best performance (it was not statistically significant) in both of one leg standing and TUG in rural area. Conclusion: Socioeconomical factors affects differently the standing balance of the elderly living in rural and urban South Korea. Female living alone in urban area with low monthly income demonstrated worst standing balance in this study.

Purpose: The purpose of this study was to develop a 12-week structured exercise program (12-week-SEP) and evaluate its effects on pain, physical function and quality of life in patients with total hip arthroplasty (THA). Methods: A nonequivalent control group non-synchronized design was utilized to examine the effects of the 12-week-SEP on patients' outcomes after THA. A total of 46 adult patients (experimental group=25, control group=21) who had THA were recruited for the study. The 12-week-SEP consisted of education, exercise (muscle strengthening and progressive walking), and feedback. Data were analyzed by SPSS/WIN 21.0 using the $x^2$ test and repeated measures ANOVA. Results: The mean age of the participants was 60.9 years and 25 men (54.5%) and 21 women (45.7%) were included in the study. There were significant intervention effects on pain reduction and increased physical function but no effects on quality of life. Conclusion: The 12-week-SEP provided pain relief and enhanced physical function in patients underwent THA. Clinical application of the 12-week-SEP can improve postoperative nursing practices for patients with THA. Future research with larger sample is of necessity to obtain greater generalizability of the empirical evidences of the 12-week-SEP.

Background: Lumbar joint dysfunction is reported to be the main cause of lower back pain (LBP). The purpose of this study was to evaluate the effect of joint dysfunction on the postural balance of the lower hack and pelvis in different normal activities such as walking or stair management. Also it was studied whether the status of LBP (intensity and duration of LBP, length of treatment) contributes to die pelvic height difference (PHD) in various postures. Subjects: 28 patients with LBP and 32 normal adult volunteers, 60 years of age or younger, who came to the Community Health Center and orthopedic clinics in Incheon, South Korea. Methods: In order to determine the accuracy of the manual angulometer method in measuring the PHD, it was compared to the pelvic x-ray method in selected subjects. In the manual angulometer method, the arm of the angulometer was placed on the top of both iliac crests. The PHD was measured in static upright stance, then one-legged stance, on the affected leg or unaffected leg each time. Information regarding the disease status was obtained through interviews. Visual assessment scale was used to grade the intensity of LBP. Data analysis was performed using SPSS 10.0/PC program. Homogeneity between the two groups was tested by 2-test and t-test. To compare the PHD of the subgroups, we used t-test, F-test and two-way ANOVA. Relationships among dependent variables were analyzed by Pearson correlation analysis. Conclusion: In patients with LBP, lumbar joint dysfunction causes lumbar and pelvic postural asymmetry during normal activities.

Purpose: The purpose of this study is to analyze the realities related with the in-home falls of the elderly and also the factors that affect on the fails. Method: The data collection was carried out from January 10 to 13, 2005. The subjects of this study were 201 in-home elderly people over age 60 who resided at G city of Jeollabuk-do. Result: The following are the results from the analysis of collected data with using the SPSS program. 1. The number of people who experienced fall injuries was 51.7% within three years. Most cases of falls occurred in winter (52.4%), on roads (52.9%), wearing sports shoes (56.7%), when walking (56.7%), loosing their balance (54.8%), and slipping (54.8%). 2. The factors yielding the difference between the groups of elderly with the experience of fail injury and the group of elderly with no experience of falls showed a statistical significance for gender (p=.000), last academic career (p=.049), and number of people in the family (p=.041). 3. Among the factors related with health, the factors yielding the difference between the group of elderly with the experience of falls and the group of elderly with no experience of fails showed statistical significance for drinking (p=.015), dizziness (p=.000) and level of drug intakes (p=.015). 4. The elderly with the experience of fall injury as compared with the group of aged people with no experience of falls showed a higher degree of depression (p=.009). 5. From the result of logistic regression analysis to explore the factors affecting the experience of fall injury, it was found that there was a significant result for gender (p=.002) and depression (p=.018). Women as compared with men and the elderly with depression showed a higher rate of danger in falls. Conclusion: Based on the above results, it is expected that fall prevention programs are needed with regard to the general characteristics and health related characteristics, that is, the individual danger factors should be focused on such depression and gender as being the most important variables affecting the experience of falls.

Purpose: The objective of this study was to define the Os submalleolare as an any ossicles below medial malleolus of tibia and to determine the characteristics of clinical and radiological characteristics and to evaluate results of surgical treatment of Os submalleolare in sports player group. Materials and Methods: Twenty-two patients with Os submalleolare were identified between November, 1, 1998 and June, 30, 2002. Results: The mean age was 18.3 years. All patient were male and soccer players comprised 71%(20 cases). Associated disease were 8 cases(29%) of chronic ankle instabilities, one case(4%) of anterior impingement syndrome and one (4%) of plantar fascitis. The most common clinical symptom was pain during walking and sports activity and sign was tenderness around medial malleolus. Only simple radiograph could reveal presence of ossicle and differentiate with acute fracture. If symptom and sign obscured, Bone scan(7 cases) and MRI(3 cases) identify causes of pain and tenderness. As a surgical treatment, all bony fragment caused symptom and sign were eliminated and medial collateral ligament was reattached meticulously. Associated chronic ankle instability were present, modified Brostrom procedure was done simultaneously. On follow-up, The symptomatic pain were wholly disappeared at average 2.2 months (1-6months) after operation. On one year follow-up, all patients have been daily life without any complaints and have gone back to the game within three months. Conclusion: as submalleolare have relatively rare incidence in sports players and most common clinical symptom and sign is tenderness on medial malleolar area of ankle, can be diagnosed both physical examination and plain X-ray film. As a treatment, Removal of ossicle and reattachment of MCL could obtain excellent or good results.

현대인들은 편리한 생활방식, 영양과잉, 운동부족 등으로 비만문제에 심각하게 노출되어 있다. 장수를 원하는 인간의 욕망이 클수록 비만문제는 중요한 사회문제가 되고 있다. 사람들은 비만을 개선하기 위해 동네 공원이나 산책로, 등산로 등을 걸으며 운동을 한다. 지자체는 주민들을 위해 산책로나 등산로에 운동표지판을 세워 각종 운동정보를 제공하며 운동을 권장한다. 그러나 기존의 운동 표지판은 붙박이 고정식이라 다양한 운동정보나 건강정보를 제공하지 못한다. 그래서 본 연구는 헬스케어 IT시대에 맞춰 스마트 헬스 스크린을 통한 과학적 운동관리를 제안한다. IT를 기반으로 한 스마트 헬스 스크린은 실시간으로 걸음수, 칼로리소모량 심박수 등의 운동정보를 제공한다. 스마트 헬스 스크린이 제공하는 체계적이고 과학적인 운동관리는 지역주민들에게 개개인에게 맞는 운동량과 강도를 조절할 수 있도록 도와준다. 더불어 특별한 비용 없이 걷기만으로도 건강관리와 비만관리가 가능하게 해준다. 우리의 연구가 비만해결에 작은 도움이 되길 바란다.

The purpose of this study was to examine the relationships between the nutrient intake and level of depressive symptoms. A total of 5,761 subjects with depression were selected for the main data analysis from a Korean National Health and Nutrition Examination Survey, KNHANES (2016), and were divided into low depressed and high depressed groups. The data were analyzed by descriptive analysis, ${\chi}^2-test$, logistic regression, and t-test using SPSS 24.0 statistics. The results revealed significant differences in the prevalence of depression according to sex (P<0.001), age (P<0.001), income (P<0.001), and education (P<0.001). Regarding the health behavior, higher stress levels (P<0.001) and smoking habit (P<0.001) appeared to be strongly associated with high levels of depression. On the other hand, the possibility of experiencing depressive symptoms was lower when the number of walking days per week was more than 3 days (P<0.05), when the number of working days per week was more than 5 days (P<0.01), and the rate of aerobic physical activity was higher. Based on the 'Dietary Reference Intakes for Koreans 2015', the subjects in the low depression group showed better intake of energy and 22 nutrients than the high depression group.

The purpose of this study was to investigate the biomechanical of K-Pop dance movement. The study was conducted on 15 male and 15 female subjects in 20-30 age groups. And they choose 150 K-Pop dance choreographies in the top 10 ranking of the main charts. We analyzed the RoM, joint moment and impulse force of the highlight movements. First, During the K-Pop dance motion, the usage of knee joints are more than the hip joints and the ankle joints, and female dancers has a larger range of motion than the male dancers. Second, male dancer uses more than female dancers when they compared the load of male dancers and female dancers. In particular, flexion and extension of the hip joints are mostly used in this study. Third, the impulse force of male dancers was greater than of female dancers, but it was statistically insignificant, this is equal to the impulse on walking. In conclusion, Female dancers use more range of motion than male dancers, but male dancer choreography requires greater torque, which can strain joints. Most choreographic exercises involve movements such as hip joint, knee joint, flexion of ankle joint, extension, rotation, and jumping.
