Overweight and abdominal obesity caused by sedentary lifestyle may induce deconditioned and atrophied extensor musculature of the lumbar spine and be a potential risk factor for low back pain (LBP). Therefore, this study was conducted to evaluate the validity of high intensity circuit training (HICT) on weight loss and subsequent alleviation of spine curvature (SC) and visual analog scale (VAS) among middle aged men with abdominal obesity. The training program (1 exercise session for 30 minutes, three times a week for 12 weeks) consisted of 12 different functional exercises based on core strengthening multiple joint circuit training. Portions of the obesity index related to body composition were positively changed, which improved the angles of thoracic kyposis and lumbar lordosis, which appeared to effectively reduce lower back pain. Taken together, HICT specifically designed for LBP effectively decreased obesity related body composition and was superior to other treatments for decreasing aggravation of the spine curvature and LBP caused by abdominal obesity; however, weight loss should be the primary treatment target for LBP patients.

This study examines the effect of oral narration learning for children's forest fairy tales on self-emotional regulation and community spirit cultivation. To achieve this aim, experiments were conducted involving 40 children in S city during 16 sessions over a period of 8 weeks. Findings showed that the experimental group with oral narration learning regarding forest fairy tales was higher than the control group, confirming the usefulness of oral narration learning for forest fairy tales. In particular, the experimental group was higher than the control group in basic lifestyle, community spirit, sociality development and self-awareness of community spirit factors. In other words, children can focus their attention on fairy tales by reading, listening and directly experiencing fairy tale materials in nature as communication with nature in forest experience activities, and can collaborate with peers based on their emotional connection with nature. Their ability to practice principles and order as well as to improve relationships with peers and increase self-emotional regulation is enhanced through experience with fairy tale stories. Such results imply that the utilization of forest fairy tales needs to be enhanced, as forest fairy tale-linked activities have a positive educational effect on community spirit cultivation as well as self-emotional regulation.

There is a cause and effect relationship in that brain injury causes impairment of mental rotation and ultimately independent functional activities. The purpose of this study was to compare the effects of mental rotation on reaction time and precision between the normal adults and chronic hemiparetic stroke patients. Thirty-one patients with chronic hemiparetic stroke and twenty normal adults participated in this study. The participants conducted 2 types of tasks for mental rotation: a comparison task using mirror images, and a rotation task using angular disparity images for 2 different 3-dimensional objects. Each of the 3 possible angled shapes ($90^{\circ}$, $180^{\circ}$, and $270^{\circ}$) appeared in each pair. The test consisted of 6 mirror-reflected image pairs and 6 angular disparity image pairs visualized during angular rotation, and 12 test periods. The subjects were judged on how accurately and rapidly they could distinguish between the mirrored and non-mirrored pairs. The study measured reaction time and precision to compare the effect of mental rotation tasks. Reaction time during all 3 angular conditions were significantly longer in the stroke patients than that in the normal adult during the comparison tasks and the rotation tasks. In addition, precision during mental rotation tasks was not significantly different between normal adults and stroke patients. Our results suggest that rehabilitation therapists should keep in mind that mental rotation is more difficult in stroke population than in normal adults.

Objectives : We surveyed this study for knowing the relation within stress, depression and medical comorbidities, and finding the risk factors of major depression. Methods : 1764 subjects were enrolled from Jan. 2009 to Dec. 2009 who visit Korea University Guro hospital healthcare center. The subjects answered the questionnaire of PSS(Perceived Stress Scale), PHQ-9(Patient Health Questionnaire-9) and the demographic data. We categorized them as the stress group, depressive group, medical comorbidity group and analyzed the correlation analyses and logistic regression analyses. Results : 198 of 1764 subjects(11.8%) were applied to major depression, and the depressive group showed the higher mean stress score(23.19) and mean depression score(12.95) than the normal group. The total PHQ-9 score was increased by perceiving more stress, having more medical comorbidities. The subjects with female, visiting due to recent health problems, irregular exercise, current smoking, history of angina and cerebrovascular disease showed the increased risk of major depression. Conclusions : In this study, we find the PSS, PHQ-9 were valuable for mental health screening in healthcare center. As perceiving more stress and having more medical comorbidity, risk of major depression were increased. Accordingly the individuals with medical diseases or unhealthy lifestyle would need the mental health screen.

This study was carried out to investigate the effect of environmental factors on 380 children's unaided visual acuity and to determine the visual acuity and objective refraction error of these children. The unaided visual acuity and objective refraction error were measured by the TOPCON chart projector and refractometer on 147 kindergarteners and 233 primary school children ranging from age 5 to 12. The measurement on the unaided visual acuity of children were 3% for below the 0.1 visual acuity 9% for 0.1~0.4. 18% for 0.5~0.7. 16% for 0.8~0.9. and 54% for over 1.0 visual acuity respectively. The refractive errors were 9.35% for mixed astigmatism. 14.5% for hyperopia 75.88% for myopia. and 0.27% for emmetropia. respectively. When analyzing the environmental factors. the relationship between the children's visual acuity and the number of hours the children watched TV. the more hours they watched TV. the more the children lost their visual acuity. The visual acuity of children decreased abruptly in the groups that watched TV more than 4 hour a day. When comparing the relationship between the children's visual acuity and proximity to the TV, the further away from the TV they were the higher visual acuity. There is rna relation between the children's visual acuity and the studying hour or reading hour of children. The relationship between the children's visual acuity and their dwelling environment, the visual acuity of children who lived in an independent house were better than the visual acuity of children who dwelled in an apartment.

Purpose: To investigate the effect of corneal unique shape to changes of refractive full corrections when pupil size changes. Methods: Subjective refraction for monocular full correction was performed to 30 subjects ($23.33{\pm}1.78$ of age, 60 eyes) in two room conditions, 760 lx and 2 lx, respectively. Pupillary diameter was measured in two conditions and the change pattern was analyzed using a peak data of corneal topography. Results: Pupillary diameter was 3.74~4.00 mm in 760 lx and 5.52~5.90 mm in 2 lx. By comparison with refractive data in 760 lx, those data in 2 lx was changed as follows: more (-) spherical power of 17 eyes (28.3%), more (+) spherical power of 10 eyes (17.7%), more (-) cylinderical power of 17 eyes (28.8%), less (-) cylinderical power of 9 eyes (15.3%), and astigmatic axis rotation of 36 eyes (62.1%). From peak data of corneal topography, the changing pattern of two principal meridians was classified into 4 types. Conclusions: Expansion of the corneal refractive surface accompanied with pupillary dilation may be a main factor that effects the changing a values of subjective refraction because of unique corneal shape. Therefore, subjective refraction should be performed under the nearest lighting condition to a main living environment.

Recently developed TRAP assay(Total Radical-trapping Antioxidant Potential) is a new technique which enable effectively the measurement of total antioxidant status in the plasma. Researches using TRAP method have rarely been reported in Korea. Therefore, we investigated effects of various life-style and dietary factors on plasma TRAP level in Korean adult population. The subjects consisted of 161 health adult male(n=105) and female (n=56) aged 19-57. A self-administered questionnaire ascertained life-style factors including smoking habits, alcohol use, physical activity. Dietary factors were analyzed by 24 hour recall method. TRAP was determined spectrophotometrically in plasma at 734nm. Mean plasma TRAP concentrations were slightly higher in males (1.35$\pm$0.02mM) and females(1.30$\pm$0.02mM) without significance. There were significant correlations between plasma TRAP levels and life-style factors including exercise and smoking Plasma TRAP levels were affected more by exercise than by smoking. Moderate amount exerciser(exercise time $\geq$30min/day) had significantly higher level of plasma TRAP levels in male smokers(1.33$\pm$0.03mM) were significantly lower than those in male nonsmokers(1.39$\pm$0.01mM, p<0.05), but the difference was not seen in female subjects. Intakes of vitamin C(r=0.288, p=0.007) or folate (r=0.258, p=0.016) were positively correlated with plasma TRAP levels in nonsmokers, but those relations were not seen in smokers. Dietary factors such as vegetables (r=0.288, p=0.007)or folate (r=0.258, p=0.016) were positively correlated with plasma TRAP levels in nonsmokers, but those relations were not seen in smokers. Dietary factors such as vegetables (r=0.277, p=0.009) and legumes(r=0.263, p=0.013) consumption were positively related to plasma TRAP concentrations also in nonsmokers only. Regular green tea drinkers showed significantly greater level of plasma TRAP than the non green tea drinkers(1.36$\pm$0.01mM vs 1.30$\pm$0.03mM, p<0.05). These results suggest that the regular exercise($\geq$30min daily), nonsmoking, and consumption of vegetables, legumes and green tea would contribute to improving plasma TRAP levels in Korean adults.

Purpose: The purposes of this study were to understand the health interest of consumers in the United States and Japan and thus understand the motivation of food choices, in order to provide basic data on the country's strategy based on healthy and correct food choices in the future. Methods: A customer survey was conducted in 2019 from October 18 to 31, and it targeted 115 American and 120 Japanese local consumers between the ages of 20- to 64-years-old. Eight questions were formed using General Health Interest. Based on food choice motivation, 27 questions were reconstructed and asked about demographic information. All data were analyzed by SPSS Statistics (ver. 25). Results: Health consciousness was categorized into 2 types: nutrition-seeking type and preference-seeking type. Based on these 2 factors, customers were grouped into 3 clusters: healthy dietary life-seeking group, nutrition balance-seeking group and health indifference group. Food choice motivation was categorized into 4 types: health, efficiency, value, and mood. All 3 groups showed a high tendency for efficiency in common. The results show that consumers want higher satisfaction with their time and money invested in food consumption. It is believed that the focus and investment of market segmentation strategy should be focused on product development, especially for American and Japanese consumers who are interested in health. Conclusion: The results of this study reflect consumer needs that can assist in the selection of healthy and correct foods in the future.
