The purpose of this study was to investigate between locus of control, body cathexis and four aspects of clothing behavior. Locus of control was measured by Rotter's The Internal-External Scale and body cathexis by Secord and Jourard's Body Cathexis Scale. Two aspects of clothing behavior were assessed with Lee's questionnaires dealing with status symbol and clothing satisfaction. Clothing Acceptance I was determined with questionnaires designed to measure the acceptance of color and casual wear and Clothing Acceptance II by line drawings of clothing representing formal type, informal type, and new mode type designed to measure the acceptance of business suits. The questionnaires in this study were administered to a sample of men (between 20 to more than 60 years of age) in Seoul. The data from 303 respondents were analyzed. The results were: 1) Locus of control was not related to Clothing Acceptance I(acceptance of color and casual wear), but positively related to Clothing Acceptance II(acceptance of business suit), that is, the persons having wider latitudes of acceptance in business suits were internally controlled in locus of control. 2) Locus of control was negatively related to status symbol, that is, the persons having higher concepts in status symbol were externally controlled in locus of control. 3) Body cathexis was positively related to clothing satisfaction, that is, the persons having higher satisfaction toward their clothing were more satisfied with their body.

Whole body fatigue detection is an important phenomenon and the factors contributing to whole body fatigue can be controlled if a mathematical model is available for its assessment. This research study aims at developing a model that categorizes whole body exertion into fatigued and non-fatigued states based on physiological and perceived variables. For this purpose, logistic regression was used to categorize the fatigued and non-fatigued subject as dichotomous variable. Normalized mean power frequency of eight muscles from 25 subjects was taken as physiological variable along with the heart rate while Borg scale ratings were taken as perceived variables. The logit function was used to develop the logistic regression model. The coefficients of all the variables were found and significance level was checked. The detection accuracy of the model for fatigued and non-fatigues subjects was 83% and 95% respectively. It was observed that the mean power frequency of anterior deltoid and the Borg scale ratings of upper and lower extremities were significant in predicting the whole body fatigued when evaluated dichotomously (p < 0.05). The findings can help in better understanding of the importance of combined physiological and perceived exertion in designing the rest breaks for workers involved in squat lifting tasks in industrial as well as health sectors.

PURPOSE: This study aimed to investigate the effect of a progressive balance training program with whole-body vibration stimulation on knee joint pain, dysfunction, psychosocial status, and balance ability in individuals aged ≥ 65 years with knee osteoarthritis. METHODS: A total of 40 individuals aged ≥ 65 years with osteoarthritis of the knees participated in the study. Using a randomization program, participants were assigned to an experimental group (n = 20) or a control group (n = 20). Both groups were assigned a knee strength training program, and a progressive balance training program with whole-body vibration stimulation was assigned to the experimental group. All interventions were conducted three times a week for four weeks. Participants were evaluated for the following: pain (numeric rating scale, NRS), knee dysfunction (Korean version of the Western Ontario and McMaster Universities Arthritis Index, K-WOMAC), fall efficacy (Korean Version Falls Efficacy Scale, K-FES), quality of life (Euro Quality of life 5 Dimension, EQ-5D), and advanced balance scale score (Fullerton advanced balance scale, FAB) before and after the intervention, and the effects of the intervention were compared accordingly between groups. RESULTS: Both groups showed significant differences in the results of the NRS, K-WOMAC, K-FES, and EQ-5D assessments before and after the intervention, and there was a significant difference in the amount of change between the two groups (p < .05). There was a significant improvement in FAB in all but items FAB 8 and FAB 9 after the intervention in the experimental group. In the control group, there was a significant improvement in FAB 1, FAB 2, FAB 7, and FAB total after the intervention (p < .05). In addition, there was a significant difference in the amount of change between the two groups in all items except FAB 8 and FAB 9 (p < .05). CONCLUSION: The progressive balance training program with whole body vibration stimulation is an effective intervention method with clinical significance in improving knee joint pain, knee disability index, psychosocial level, and balance ability in adults aged ≥ 65 with osteoarthritis of the knees.

Purpose: This study compared the body composition and health conservation of low and high physical activity groups in professional retired elderly. Methods: The participants were 132 professional retired elders using a university of education for the elderly and senior welfare centers in D and K city. Data were collected through interviews from November to December in 2015. The body composition was measured using an Inbody 230 and the health conservation was measured using Sung's (2005) Health Conservation Scale. The low and high physical activity groups were divided by CHAMPS (The Community Healthy Activities Model Program for Seniors Questionnaire). The collected data were analyzed using a $x^2$ test, independentt-test, andbinary logistic regression using the SPSS/WIN 20.0 program. Results: The body composition (body mass index, body fat percentage, and fitness score) and health conservation score were higher in the high physical activity group than in the low physical activity group. The result shows that the body weight (OR=10.62) is the highest risk factor influencing the physical activity in professional career-retired elders. Conclusion: These results suggest that to induce physical activity level among professional retired elders, nursing interventions are needed to increase the health conservation and body composition, particularly in controlling the body weight.

The present study aims to investigate characteristics of the flow structures around the Ahmed body by using both experimental and numerical methods. Therefore, 1/4 scale Ahmed body having $25^{\circ}$ slant angle was employed. The Reynolds number based on the body height, H and the free stream velocity, U was $Re_H=1.48{\times}10^4$. Investigations were conducted in two parts. In the first part of the study, Large Eddy Simulation (LES) method was used to resolve the flow structures around the Ahmed body, numerically. In the second part of the study the particle image velocimetry (PIV) technique was used to measure instantaneous velocity fields around the Ahmed body. Time-averaged and instantaneous velocity vectors maps, streamline topology and vorticity contours of the flow fields were presented and discussed in details. Comparison of the mean and turbulent quantities of the LES results and the PIV results with the results of Lienhart et al. (2000) at different locations over the slanted surface and in the wake region of the Ahmed body were also given. Flow features such as critical points and recirculation zones in the wake region downstream of the Ahmed body were well captured. The spectra of numerically and experimentally obtained stream-wise and vertical velocity fluctuations were presented and they show good consistency with the numerical result of Minguez et al. (2008).

BACKGROUND/OBJECTIVES: Studies have indicated that university students majoring in nutrition and dietetics or sport sciences may have more obsessions associated with eating attitudes and body shape perception compared to other disciplines i.e. social sciences. Therefore, this study aimed to assess and compare the risk of eating disorders and body shape perception. MATERIALS/METHODS: Data was collected from 773 undergraduate students at the Departments of Nutrition and Dietetics (NDD) (n = 254), Physical Education and Sports (PESD) (n = 263), and Social Sciences (SOC) (n = 256).A socio-demographic and personal information questionnaire, Eating Attitudes Test (EAT-40), Body Shape Questionnaire (BSQ-34), Perceived Figure Rating Scale (FRS) were applied; and body weights and heights were measured. RESULTS: Mean EAT-40 scores showed that, both male and female students of PESD had the highest scores ($7.4{\pm}11.6$) compared with NDD ($14.3{\pm}8.3$) and SOC ($13.0{\pm}6.2$) (P < 0.05). According to EAT-40 classification, high risk in abnormal eating behavior was more in PESD (10.7%) compared to NDD (2.9%) and SOC (0.4%) students (P < 0.05). Students of PESD, who skipped meal, had higher tendency to the risk of eating disorders (P < 0.05). In parallel, body shape perception was found to be marked with higher scores in NDD ($72.0{\pm}28.7$) and PESD ($71.5{\pm}32.8$) compared with SOC ($64.2{\pm}27.5$) students (P < 0.05). Considering BSQ-34 classification, high concern (moderate and marked) for body shape were more in PESD (7.4 %) compared to NDD (5.2%) and SOC (1.9%) students (P < 0.05). The body size judgement via obtained by the FRS scale were generally correlated with BMI. The Body Mass Index levels were in normal range (Mean BMI: $21.9{\pm}2.8kg/m^2$) and generally consistent with FRS data. CONCLUSIONS: Tendency to the abnormal eating behavior and substantial body shape perception were higher in PESD students who have more concern on body shape and were not well-educated about nutrition. In conclusion, substantial concern on physical appearance might affect eating behavior disorders in PESD students.

The purpose of the study was to investigate the interaction effect of garment formality, Yin -Yang level, and body type of children on impression formation. The experimental materials developed for the study were a set of stimuli (8 color photographs) and a response scale (34 bipolar adjectives) and the subjects were 267 elementary school teachers in Taejon area who were responsible for the first grade students. Results were as follows; The 3 independent variables showed significant effects on impression of the 4 factors (sociability, potency, dynamics, cooperation) of impression. Since body type had interaction effects with garment formality and subject's gender, the two body types were separately analyzed. For the normal body type, only the garment formality affected on impression of cooperation factor But for the large body type, garment formality affected on impression of potency dimension, garment Yin-Yang level affected on social and dynamics dimension, and subject's gender affected on social and cooperation dimensions. The body type was the most salient variables and clothing effects for the large body type was significantly different for the normal body type. It is concluded that the results support the cognitive categorization theory on impression formation.

The purpose of this study was to examine the relationship of participation in jazz dance to body image and mental health in an attempt to make a contribution to the spread of jazz dance. The subjects in this study were 183 people who were selected by purposive sampling from a population of Seoul and Gyeonggi province residents who were at the Western age of 18 and up. The selected people took general education courses at colleges, attended cultural centers or fitness clubs, or learned dance for all. One instrument used in this study to assess their body image was Jourard and Secord(1954)'s Body Cathexis Scale, which was modified into six factors and 39 items. The other was Kim Gwang-il, et. al.(1978)'s 46-item inventory, which translated Rickles and Rock(l976)'s SCL-90 with 90 items to suit Korean circumstances. That inventory was modified into 31 items and four factors. For data handling, factor analysis, reliability analysis, regression analysis and path analysis were utilized. The findings of the study were as follows: 1. The extent of jazz dance participation had an impact on their body image. Those who performed jazz dance more frequency had a better image about their health and the lower part of the body. 2. The level of jazz dance participation exerted an influence on their mental health. A longer participation term led to more interpersonal sensitivity, and a higher participation frequency was followed by more somatization. 3. Concerning the causal relationship of participation in jazz dance to body image and mental health, the participation frequency affected health, the image of the lower part of the body and somatization in the firsthand manner, and the image of the lower part of the body had a firsthand impact on interpersonal sensitivity, hostility, anxiety and depression. Accordingly, the image of the lower part of the body played a crucial role as a parameter in the relationship between the jazz dance participation frequency and mental health.

The transient incompressible flow behind the axisymmetric bluff body is numerically simulated using the random vortex method(RVM). Based on the vorticity formulation of the unsteady Navier-Stokes equations, the Lagrangian approach with a stochastic simulation of diffusion using random walk technique is employed to account for the transport processes of the vortex elements. The numerical solutions for 2-dimensional recirculating flow behind a backward-facing step in the laminar range of Reynolds number are compared with experimental data. The present simulation focuses on the transitional flow regime where the recirculation zone behind the bluff body becomes highly unsteady and large-scale vortex eddies are shed from the bluff body wake due to intrinsic shear layer instabilities. The unsteady vertical flow structures and the mixing characteristics behind the bluff body are discussed in detail.
