Purpose: This study was done to identify practical exercise performance and to define the factors related to exercise performance in middle-aged women. Methods: The researchers collected data from 206 middle-aged women, ages 40 to 59. The measurements used were a scale for degree of exercise performance, and self-efficacy scale, affect, perceived barriers and benefits related exercise, body-shape perception, and the youngest child's education stage. The data were analyzed with SPSS/WIN 17.0 and SAS program using t-test, ANOVA, and stepwise multiple regression. Results: Exercise performance showed significant differences according to body-shape perception (F=5.45, p<.01), the youngest child's education stage (F=4.44, p<.05). Exercise performance had a significant strong positive relation with self-efficacy (r=.616), a moderate relation with self-rated health (r=.428) and with affect related exercise (r=.519), a mild relation with perceived benefits (r=.339) and with social support (r=.239), and a negative mild relation with perceived barriers (r=-.330) with 99% significance. Self-efficacy, affect, perceived barriers, and the youngest child's education stage explained 46.4% of a variance in exercise performance in middle-aged women. The factor most influencing was self-efficacy related exercise at 37.9% of the variance. Conclusion: We can conclude that self-efficacy, affect, perceived barriers, and the youngest child's education stage should be considered as important factors for developing program of middle-aged women.

The purpose of this study is to identify the effect of perceptions of somatotype on the satisfaction of somatotype and the clothing behavior. The respondents included 201 female student volunteers, aged 19 to 27, who were enrolled at university in Busan. The questionnaire was composed of three sections; perceived somatotype-self, satisfaction of somatotype and clothing behavior. Data were analyzed by frequency, factor analysis, and regression analysis. This study established the factors(the lower half the body, the upper half of the body, height, body-shape)as the perception of somatotype. In the clothing behavior, this study drew the 3 factor(aesthetics, fit, utility). The result of regression analysis reveals that the perceptions of somatotype-self are major determinant to influence on the satisfaction of somatotype. But the perceptions of somatotype-self are major determinant to influence on the aesthetic factor among three factors.

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.

Lookism is spread largely because many people think beautiful people are treated better and receive more favors. This trend has been influenced by mass media and impacted by commercial marketing strategy. The expectation for the beauty have risen higher than ever. People expect beautiful body and beautiful face which are more difficult to meet the standard of beauty. People desire tall and skinny body. The purpuse of this study was to find out body image from college females in the age which they are very sensitive to appearance. This research focused to find out how they perceived their own body shape and their perception of the most ideal body shape. Measuring tool for the research was 9 pictures of body silhouette from very skinny to very fat. To analyse the respondents' objective body image, Body Mass Index were employed. The result of this research indicated that there were distinct differences between their subjective body images and ideal body images. This result indicated that they were not satisfied with their own body shape and hence they were not confident towards their body images. Even though their objective bodies were normal or under weight, they still felt they were over weight. This meant their body images were misrepresented. They preferred thinner bodies even though their bodies were perfectly normal and healthy. But these misrepresented body images could be unhealthy physically, psychologically, or socially. These results showed that college females were overly obsessive with superficial appearance rather than improving ones capability to be more competitive in the society. From this research, I tried to find out perception of body image and it's distortion which was debated a lot in our society. I also want to provide basic reference material for establishing the body image study.

The purpose of this study was to compare the perception of men's lower body shape in the 60s with that in the 20s. On hundred and seven men in the 60s and 178 men in the 20s participated in the survey and measurements. The results were as follows : 1. It was perceived that men in the 60s had broader girth but lighter weight than men in the 20s. The research revealed that men in the 60s was more satisfied with their lower body shape than men in the 20s. 2. It was also found that the ideal size of men in the 60s was broader in the girth of their waist and hip, shorter in their height, and lighter in their weight compared to men in the 20s. 3. It showed a difference in the satisfaction with their body shape between men in the 60s and the 20s. The satisfaction with their lower body shape of men in the 60s was more affected by their perception than by their real measured size. On the other hand, the satisfaction of men in the 20s was affected by their perception as much as by their measured size. 4. If we look at the perception and satisfaction in relation with their body types, we found that there was a difference in the girth of their waist, abdomen, hip, and weight depending on their body types. And men in the 20s showed greater differences in their perception and satisfaction depending on their body types, compared to men in the 60s. 5. The measured size of men in the 20s had greater differences depending on their body types than that of men in the 60s. On the contrary, the ideal size of men in the 60s had greater differences than that of men in the 20s.

The purpose of this study was to determine the recognition of body image and food behavior factors according to the BMI. The subjects of this study were 242 7th grade students resided in San Francisco area. The degree of recognition for self-estimated physique of subjects by gender and by race showed no significant differences by gender but significant differences by race, showing that 20.0% was considered as underweight in Asian and 7.5% was considered as underweight in White students. This showed the same tendency as actual physique status (BMI). Also, the ratio of being recognized as more than overweight was 17.3% in Asian, 23.3% in Hispanic, and 13.4% in White students. In case of female students, the ratio of dieting experience was 63.3%, and 49.3% of White students and 63.3% of Hispanic students experienced dieting. In case of students answered not healthy, their body weight were significantly higher than those answered as healthy, and the BMI was also over 19, showing significant differences. Thus cases that answered as not healthy had greater body weight and BMI. Also it showed that frequent dieting experience is related to higher height and weight. The analysis of food behavior factors perceived by body shape showed that the group perceived itself as overweight consumed more 'fast food' but had low scores in 'vegetables' intake, with frequent intake of 'soda' and tendency to 'overeat'. Also, the tendency for 'balanced life' was significantly lower and for skipping breakfast was significantly higher, suggesting problematic food behavior.

Purpose: The Purpose of this study was to examine the degree of obesity stress and analyze factors having an effect on obesity stress among college women. Method: The subjects were 347 female students from a university in J City. Data were collected using a self-report questionnaire for general characteristics, health-related characteristics, and current and preferred somatotype. Obesity stress was measured using 10 items developed by Cho (1996) based on Body Attitudes questionnaire (BAQ) of Ben-Tovim and Walker (1991). The survey was conducted from September 4 to September 7, 2007. Data were analyzed by t-test, ANOVA, Scheffe test, Spearman's rank correlation test, and stepwise multiple regression using SPSS 14.0. Results: The average score of obesity stress was $2.78{\pm}0.90$ out of 5.00. Stepwise multiple regression analysis showed that the major factors that affect obesity stress of female college students were perceived body shape, disagreement between current and preferred somatotype, history of weight control, body mass index (BMI), and perceived health status, and these factors explained 38.4% of obesity stress. Conclusion: Subjective judgment in the perception of or preference for body shape was the most important factor affecting obesity stress in female college students. Therefore, a plan is necessary to mitigate obesity stress and evaluate individually subjects who perceive themselves to be fat or want to be thinner than the current somatotype. And consultation and constant management are needed to help the high risk group (experience of weight control, BMI ${\geq}23kg/m^2$, not good health status).

Wearable devices, attached to the human body, track and enhance users' activities, health, and communication. Therefore, considering ergonomic factors in product design is crucial. However, previous research has somewhat overlooked the importance of integrating ergonomic design elements into a broad spectrum of design factors. This study aims to examine the impact of physical attributes inherent in smart wristbands and smartwatches on the perceived functional value, specifically, perceived usefulness, ease of use, and fit. A survey was conducted among 289 US adults who had experience using smart wristbands or smartwatches. The collected data were analyzed using descriptive statistics, factor analysis, Cronbach's alpha, t-test, MANOVA, and regression analysis in SPSS version 29. The results showed that the shape of the front display significantly influenced perceived ease of use, and the product's weight had a substantial impact on both perceived ease of use and fit. Furthermore, distinct technical features on the front display had varied effects on perceived usefulness, ease of use, and fit. Notably, the presence of activity tracking, alarm, and calendar functionalities led to distinct differences in ease of use and fit. Features such as distance tracking, phone call, social media notifications, text messaging, and time display functions showed significant influences on the perception of fit. These findings provide insights into the physical values of smart wristbands and smartwatches as perceived by users.

This study was performed to investigate the body image perception by BMI and the dietary behaviors in 803 college students(408 males and 395 females). The degree of obesity was divided into an underweight group with BMI less than $18.5kg/m^2$, a normal group with BMI of $18.5{\sim}22.9kg/m^2$, an overweight group with BMI of $23{\sim}24.9kg/m^2$ and an obese group with BMI over $25.0kg/m^2$. The average ages of subjects were 22.9 years in males and 20.2 years in females. The average weight and height of male subjects were 175.3 cm and 69.6 kg, respectively and those of female subjects were 162.5 cm and 52.0 kg, respectively. The average BMIs of male and female subjects were $22.6kg/m^2$ and $19.7kg/m^2$, respectively. The distribution of subjects who perceived their current body image as ideal body image was 25.7% in males and 10.9% in females, showing that the body image satisfaction of male subjects was 1.5 times higher than that of female subjects. Body image perception for their own bodies was mostly shown as the average or standard shape both in males and females with 64.2% and 54.2%, respectively, but males showed a higher perception rate than females and 31.1% of females and 19.5% of males perceived their bodies as lean shape(p<0.01). The body image satisfaction was 4.20 in males and 3.70 in females, showing more satisfaction in the male subjects(p<0.001). The correlation between body image and physical variables in male subjects indicated that CBI and IBI showed statistically significant correlation and also BMI showed statistically significant correlation with IBI(p<0.001) and CBI(p<0.001). The frequency of eating out increased as the frequency of skipping meals increased(p<0.001) and the frequency of having snacks increased as the frequency of eating out increased(p<0.01). The correlation between body image and physical variables in female subjects showed that CBI and IBI(p<0.001) had statistically significant correlation. Body weight showed statistically significant correlation with CBI(p<0.001), BMI(p<0.001) and height(p<0.001). The frequency of eating out increased as height(p<0.01) and the frequency of skipping meals(p<0.001) increased. When both male and female subjects wanted leaner body shapes, they preferred much leaner shapes despite their current body images belonging in the normal range. Additionally subjects preferred the body image in the normal range in cases when their current body images were lean. In particular, more female subjects had strong desires to become leaner in their body images than male subjects, which could be analyzed as a risk factor for physical him. From the above results, it is considered that both male and female subjects need to establish proper recognition and dietary behaviors for their body images and also need nutritional education and counseling for desirable weight control methods.
