Purpose: Malalignment of the lower limbs may increases the difficulty of maintaining equilibrium. The purpose of this study was to study the effects of genu varum and poor posture in the sagittal plane on postural stability. Methods: We had 27 subjects with varus and 27 normal subjects participate in this study. Subjects for whom the distance between the medial epicondyles in the knee joint was more than 3 cm were classified as varus group, and subjects for whom the distance was less than 3 cm were classified as normal group. The measurements of static and dynamic stability were used overall stability index (OSI), anterioposterior stability index (APSI), and mediolateral stability index (MLSI) using a Biodex balance system. Results: When measuring the static stability index, there were significant differences in the mediolateral stability index between the varus and control groups. When measuring the dynamic stability index, there were significant differences in the overall, anteriorposterior, and mediolateral stability index between the varus and control groups. These results demonstrated that genu varum affects mediolateral movement in static stability, and overall, anterioposterior and mediolateral movements in dynamic stability. Conclusion: As genu varum affects static and dynamic stability in young adults, it increases the risk of injuries or falls. Exercise and surgery are required for realigning the genu varum. Future studies about postural stability in young children and elderly people who have a risk of falls due to lower postural control ability, are needed, as well as in young adults.

Background: In the rehabilitation of stroke patients, regular physical activity is very important not only as a treatment for maximal functional recovery but also as a strategy to prevent the recurrence of stroke. The purpose of this study was to objectively measure the amount of physical activity in people with stroke, and to examine the differences in motor and cognitive function according to a level of physical activity. Design: A cross-sectional study. Methods: Physical activity (GENEActiv), motor function (Fugl-Meyer Assessment), cognitive function (Montreal Cognitive Assessment-Korean version), and the Korean version of Modified Barthel Index were evaluated in adult stroke patients with hemiplegia. Results: There was no statistically significant difference in the level of physical activity according to the motor and cognitive function. There was no statistically significant difference in motor and cognitive function according to the level of physical activity, but there was a statistically significant difference in the MBI (p<.01). Conclusion: As a result of the difference in the MBI according to the level of physical activity, it was found that the more moderate to vigorous physical activities are performed, the higher the independence in daily living. These results can be interpreted as that the more often you participate in physical activities such as physical therapy (gait training), the better your independence in ADL. Since regular physical activity participation of adult stroke patients can improve daily living performance, it is considered necessary to participate in physical activities such as continuous physical therapy.

Purpose: The purpose of this study is to compare the differences between obese and non-obese students in sedentary leisure-time activities. Methods: The survey was performed with 725 students from 3 different middle schools in Kyeonggi-do. In order to measure the degree of obesity. used are BMI and "2007 Korea Children and Adolescents' Average Scale". With regard to the leisure activities. YRBS and "youth Behavior Risk Factor Surveillance" were referred. Results: The rate of boys' overweight was 18.0% and that of girls was 11.8%. Students watching TV 3hours+/day were 16.6% for boys and 30.6% for girls during weekday. Respective values for weekend were 56.8% and 71.4%. Students using computer 3hours+/day were both 14.5% for boys and girls during weekday. and 53.7% for boys and 36.7% for girls during weekend. 14.9% of boys and 21.2% of girls didn't participate in vigorous physical activities and 5.9% for boys and 11.2% for girls didn't participate in moderate physical activities. The differences between obese and non-obese students in sedentary activities were not significant. However. the difference in leisure-time activity was significant. Conclusion: The programs for prevention and management of adolescents' obesity have to be focused on reducing their sedentary activities and improving physical activities.

Purpose: The purpose of this study was to show the effect of walking exercise on physiological index, physical fitness, self-esteem. depression. and life satisfaction in institutionalized elderly women aged over 70. Sample and Method: Data were collected from subjects who consented to participate in this program for eight weeks from the 2nd of July to the 27th of August 2005. The subjects were divided into two groups, 26 subjects in the experimental group who had walking exercise and 30 in the control group who did not have walking exercise. The intensity of the walking exercise allowed 50-65% of the maximum heartbeat. Results: The results of the experiment supported the hypothesis that the experimental group would have higher flexibility, left grip strength, sense of equilibrium, self-esteem and life satisfaction and lower depression than the control group. Conclusion: Walking exercise has the effect of decreasing diastolic blood pressure together with improvement in flexibility, left grip strength, sense of equilibrium, self-esteem, depression and life satisfaction for institutionalized elderly women aged over 70. According to the results presented above, walking exercise can be strongly recommended for improving the health of institutionalized elderly women.

Purpose : This study aims to present a rehabilitation exercise and physical education program (REPEP) for local community stroke patients by examining an exercise program provided from traditional physical therapeutic perspectives. Methods : The subjects were 40 stroke patients residing in a local community and managed by a public health center (the group-exercise group: 20, the individual-exercise group: 20). In the case of the group-exercise group (GEG), the subjects were divided into small groups composed of five members each to participate in the program. The individual-exercise group (IEG) took part in the program individually. The subjects received a REPEP that included a warm-up exercise, an elastic band exercise, a leg exercise, a balance and gait exercise, an arm and trunk exercise, and a cool-down exercise twice per week for 20 weeks. They had their gait function, balance index, and muscle strength in the bilateral knee joints tested before and after the experiment. Results : Compared to before the experiment, both groups' gait function, balance index, and muscle strength in the knee joints increased after the experiment. After the experiment, the GEG experienced more improvement in their gait function, balance index, and muscle strength in the bilateral knee joints, excluding their gait velocity and $300^{\circ}/sec$ flexion and extension, than the IEG (p<.05). Conclusion : An exercise program provided from the traditional physical therapeutic perspectives may be applied to stroke patients as their REPEP. In addition, a REPEP was more effective in improving their gait function, balance index, and muscle strength in the knee joints when the subjects formed a group and took part in the program than when they partook in it individually.

The cold surges over East Asia can be grouped to two types of the wave-train and the blocking. Recently, the observational study proposed new dynamical index to objectively identify cold surge types. In this study, the dynamical index is applied to the simulations of 10 climate models, which participate in the Coupled Model Intercomparison Project Phase 5 (CMIP5). Focusing on assessment of cold surge simulation, we discuss characteristic of the wave-train and blocking cold surges in the climate models. The wave-train index (WI) and the blocking index (BI) based on potential temperature anomalies at dynamical tropopause over the subarctic region, the northeast China, and the western North Pacific enable us to classify cold surges in the climate models into two types. The climate models well simulate the occurrence mechanism of the wave-train cold surges with vertical structure related to growing baroclinic wave. However, while the wave-train in the observation propagates in west-east direction across the Eurasia Continent, most of the models simulate the southeastward propagation of the wave-train originated from the Kara Sea. For the blocking cold surges, the general features in the climate models well follow those in the observation to show the dipole pattern of a barotropic high-latitude blocking and a baroclinic coastal trough, leading to the Arctic cold surges with the strong northerly wind originated from the Arctic Sea. In both of the observation and climate models, the blocking cold surges tend to be more intense and last longer compared to the wave-train type.

This study examined the tongue coating index and halitosis to determine the association with the oral care behavior and variation in halitosis according to the tongue coating index, dental calculus, and the oral environment before and after scaling among 130 participants in scaling practices of the Department of Dental Hygiene at K University in Daejeon. The subjects were asked to participate in a survey, in an oral examination for the tongue coating index, dental plaque, and dental calculus status, and in halitosis measurement. The tongue coating most significantly affected halitosis and the tongue coating index was strongly correlated with smoking and tongue washing. More frequent toothbrushing, a lower level of halitosis; and nonsurgical treatment of scaling were effective in reducing halitosis; age was associated with the tongue coating index. Therefore, it will be necessary to perform good oral care and reduce the amount of dental plaque and tongue coating and undergo regular scaling with the objective of improving oral health and reducing halitosis.

This study used a structured questionnaire to analyze the effects of oral habits and stress on temporomandibular disorders in high school students. A total of 339 students attending high schools in Ulsan agreed to participate in the study. Data was analyzed using the SPSS Statistics ver. 18.0 for Windows program, t-test, one-way ANOVA, correlation, and regression analysis. Our results reveal that the temporomandibular disorder index is statistically correlated with the oral habit index, school life stress index, family life stress index, interpersonal stress index, and egosphere stress index (p≤0.01). The oral habit index had maximum influence on the temporomandibular disorder index. Moreover, higher the stress level in egosphere stress, greater significant differences were observed in the temporomandibular disorder index (p≤0.01). In other words, persistence of oral habits and non-addressal of stress increased the likelihood of experiencing temporomandibular disorders in adulthood. This was determined by the regression formula Y (temporomandibular disorder index) = 2.563 + 0.550X1 (oral habit index) + 0.134X2 (egosphere stress index). Thus, bad oral habits and stress in adolescence can be the potential cause of jaw joint disorders in adulthood. We believe that measures are needed to actively recognize and improve oral habits, and properly cope with stress during adolescence.

This study was conducted to examine the effects of a healthy dietary life and purchase of environmental-friendly food materials according to a mother's lifestyles of health and sustainability (LOHAS) attitudes. The subjects consisted of 295 mothers. The findings are summarized as follows. The mother's LOHAS attitude index averaged 3.39 points out of 5 points. High LOHAS attitude items were "I participate actively in separating the trash collection" (4.16 points), and "I recycle dresses that I do not wear by taking them to the recycling center" (4.08 points). In contrast, LOHAS attitude items for "I do community service activity on the weekend" (2.57 points), and "I try to serve in the local community" (2.63 points) scored very low. A high LOHAS behavior index occurred for mothers who were "resource saving", whereas "social welfare" scored low. Mother's intention to purchase environmental-friendly food materials averaged 3.61 points. Mother's health dietary life attitude score averaged 3.52 points. When age, monthly income, and the environmental-friendly food materials purchase ratio of the mother was high, the health dietary life performance was high. The LOHAS attitude index of mothers had an impact on the purchase intention of environmental-friendly food materials in resource saving and environmental-friendly oriented propensity groups. The LOHAS attitude index of mothers impacted healthy dietary life in environmental-friendly, family and health oriented propensity groups.
