Purpose: Flexed posture commonly increases with age in older women and is characterized by an excessive curvature in the thoracic spine (kyphosis), forward head posture, and decline in height. This study was conducted in order to determine the relationship between flexed posture, physical performance, and psychosocial factors in community dwelling elderly women in Korea. Methods: Fifty-two subjects with thoracic kyphosis of $40^{\circ}C$ or greater participated in this study. Flexed posture was measured using kyphosis angle (KA), forward head posture (FHP), and round shoulder (RS), and physical performance was evaluated using the short physical performance battery (SPPB), grip strength, and static and dynamic balance. Psychosocial factors were measured using depression and the quality of life (QOL). All data were analyzed using SPSS 18.0 software for windows. Results: KA showed significant correlation with SPPB score (r=-0.447) and dynamic balance (r=0.426) (p<0.05) depression (r=0.405) and QOL (r=-0.464) but not with grip strength and static balance in elderly individuals. FHP and RS showed significant correlation with SPPB score (r=0.002, r=-0341) and dynamic balance (r=-0.278, r=0.346) (p<0.05) but not with psychosocial factors. Conclusion: These findings suggest that flexed posture provides meaningful information about physical performance and psychosocial factors in elderly women. Our data suggest that the flexed posture may need to be addressed as part of the health management process for elderly women.

[Purpose] The purpose of this study was to comparatively investigate the correlation among body composition, resting metabolic rate (RMR), and physical activity (PA) between young and middle-aged Korean adults. [Methods] A total of 53 [male n=23, female n=30] subjects were included in this study, among whom 34 subjects were healthy young adults [male n=18, female n=16] and 19 were middle-aged adults [male n=5, female n=14]. The body composition and RMR of all the participants were measured after overnight fasting (≥8 h). The Korean version of the WHO Global Physical Activity Questionnaire (GPAQ) was used to assess physical activity. [Results] Body composition was not significantly different between young adults and middle-aged adults. Whole-body bone mineral density and bone mineral contents (BMC) were significantly lower in middle-aged adults than in young adults. Total blood cholesterol (TC) and blood glucose levels were significantly higher in middle-aged adults (TC; 195.21 ± 43.34, glucose; 103.57 ± 12.61 mg/dL) than in young adults. RMR was significantly lower in middle-aged adults (1619.57 ± 290.28 kcal/day) than in young adults (1894.37 ± 405.00 kcal/day). In middle-aged adults physical activity (PA). PA (METs, min, EE) was inversely correlated with fat mass (FM, kg, and %) and blood triglyceride (TG) level in young adults. In middle-aged adults, PA showed a significant positive correlation with lean body mass (LBM), FM (%), and RMR. Furthermore, PA EE showed significant interrelatedness with BMC among middle-aged adults. [Conclusion] These results demonstrated that high PA levels enable LBM and RMR maintenance in middle-aged adults. Furthermore, in young adults, more PA is required to induce change in body composition.

The purpose of this study was to investigate the relationship between iron deficiency without anemia and physical performance in healthy women aged 20-21 yrs. Ten subjects with normal iron stores (serum ferritin $\geq$ 12$\mu\textrm{g}$/L: iron-sufficient group) and 11 subjects with iron depletion without anemia (serum ferritin < 12 $\mu\textrm{g}$/L and serum hemoglobin > 120 g/L: iron-depleted group) were chosen from a group of 50 women and were given physical-performance tests, including determinations of maximum oxygen consumption (VO$_2$ max) and ventilatory threshold. Iron status assessment included determination of hemoglobin, hematocrit, seam ferritin, total iron-binding rapacity, serum iron and transferrin saturation values. Dietary iron intake was assessed based on seven-day food intake records written by the subjects. Physical activity level was estimated by frequency questionnaires and two-week physical activity records were compiled daily by the subjects. Blood ferritin concentration was significantly lower in the iron-depleted group than in the iron-sufficient group (p < 0.05). However, other variables showing iron status was not different between the groups. There were no significant differences in body size, body composition and physical activity levels between the groups. Daily dietary iron, total protein and animal protein intakes of the iron-sufficient group were significantly higher than those of the iron depleted group. However, no differences were found in the amount of dietary vitamin C and fiber between the groups. The values for VO$_2$max and VO$_2$max corrected with weight or fat-free mass were not different between the groups. However, the ventilatory threshold was significantly higher in the iron sufficient group than in the iron-depleted group. The lower ventilatory threshold in the iron-depleted group suggests that iron depletion without anemia could diminish aerobic physical performance in young women. In addition, a significant correlation of physical performance to serum fferritin level was shown only in the iron depleted group.

Purpose: The purpose of this longitudinal study was to examine the relationship between postpartum care performance and postpartum health status. Sample: The study subjects were 82 mothers who delivered full-term infants at 3 hospitals at P city. Data were collected for their health status at the postpartum unit and the sample was followed up to 6 weeks postpartum to collect postpartum care performance and health status. Results: Mothers rated postpartum care performance as moderate to high and especially rated the maternal role attainment the highest. Mothers experienced 4 physical symptoms and moderate levels of fatigue. In addition, they experienced moderate levels of positive affect and low levels of negative affect at both times. Canonical correlation revealed that ostpartum care performance was related to postpartum health status with 2 significant canonical variables. The first variate indicated that mothers who performed hospitality, physical and emotional recovery, self-caring, and role attainment well showed higher positive affects, lower negative affects, fewer physical symptoms, and lower levels of fatigue. The second variate showed that the greater the performance of caring and physical and emotional recovery, the fewer physical symptoms and lower levels of fatigue. Conclusion: Although Korean traditional postpartum care performance was related to postpartum health status, the further study is needed to identify the causal relationship between them. Nurses need to integrate the perspective of westernized postpartum care and Korean traditional views of postpartum approach to maintain and promote women's health.

Actoprotectors are preparations that increase the mental performance and enhance body stability against physical loads without increasing oxygen consumption. Actoprotectors are regarded as a subclass of adaptogens that hold a significant capacity to increase physical performance. The focus of this article is studying adaptogen herbs of genus Panax (P. ginseng in particular) and their capabilities as actoprotectors. Some animal experiments and human studies about actoprotective properties of genus Panax attest that P. ginseng (administered as an extract) significantly increased the physical and intellectual work capacities, and the data provided suggests that ginseng is a natural source of actoprotectors. Preparations of ginseng can be regarded as potential actoprotectors which give way to further research of its influence on physical and mental work capacity, endurance and restoration after exhaustive physical loads while compared with reference actoprotectors.

Unreinforced masonry (URM) buildings are known to be highly vulnerable to seismic loadings. Although significant physical variation may exist for URM buildings that fall into a same structural category, a single set of fragility curves is typically used as a representation of the seismic vulnerability of the URM structures. This study investigates the effect of physical variation of URM structures on their seismic performance level. Variables that describe the physical variation of the structure are defined based on the inventory analysis. Seismic behavior of the structures is then monitored by changing the variables to investigate the effect of each variable. The analysis results show that among the variables considered the seismic performance of URM building depends on the variation of the width, the aspect ratio, and the number of story. The need for further research on the modeling of the connections between the walls and diaphragms and the torsional effect is also addressed.

PURPOSE: Many studies have reported the improvement of cognition through physical activity among subject with dementia. This study aimed to whether the current studies supports that physical activity intervention is efficacious on cognitive performance in subject with dementia. METHODS: Two independent reviewers searched National assembly library, RISS, KISS (2005-2015) using the concepts of dementia, exercise, and physical activity. We included randomized controlled trials that examined the efficacy of physical activity in subject with dementia. A meta-analysis was performed to estimate the effect sizes cognition with CMA (Comprehensive Meta-Analysis, version 2.2.064) soft-ware program. Nine randomized controlled trials were included, providing data from 133 individuals and excluding those failing to criteria of this study. RESULTS: The meta-analysis showed that physical activity intervention had a rather small effect sizes of 0.36 (95% confidence interval 0.14-0.59) on cognition performance in subject with dementia. Outcome measurement were MMSE-K (Mini-mental state examination Korean version) and LOCTA (Loewenstein Occupational Therapy Cognitive Assessment). We found heterogeneous among studies and there was difference between the studies (Q = 19.63, d(f)=12, $I^2= 38.88$). CONCLUSION: The present analysis suggests that physical activity interventions have the low effect sizes on cognition performance in subject with dementia Further studies will be required to develop the various programs for improving the cognitive performance in subject with dementia.
