The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

Objective: The purpose of this study was to investigate the effect pf flexibility of hip flexor muscles on a conventional deadlift movement. Method: Eighteen healthy male were participated in this study and were divided into normal group (NG: age: 24.0±1.8 yrs, height: 174.5±2.37 cm, body mass: 74.4±5.5 kg, 1RM: 138.0±23.8 kg) and restricted group (RG: age: 24.6±1.7 yrs, height: 171.5±5.3 cm, body mass: 74.0±5.7 kg, 1RM: 137.5±18.3 kg) by Thomas test, which measure flexibility of hip flexor muscles. A 3-dimensional motion analysis with 8 infrared cameras and 3 channels of EMG was performed in this study. A two-way ANOVA (group x load) with repeated measure was used for statistical verification. The significant level was set at α=.05. Results: RG revealed significantly increased muscle activation in erector spinae on 70% and 90% of 1RM and decreased muscle activation in gluteus maximus on 90% of 1RM compared to NG (p<.05). For the muscle activation ratio for agonist to synergist, erector spinae showed the difference in 90% of 1RM while hamstring was observed differences in all loads (p<.05). Conclusion: Our results indicated that hip flexibility affects conventional deadlift movement. Therefore, it is necessary to assess the flexibility of the hip flexor muscles before performing the movement and, as needed, to train to address the lack of flexibility.

The purpose of this study is to examine the differences in appearance management behaviors and demographic variables among groups classified by the appearance management motives. The questionaries are administerd to 493 female and male adults above 20 years old in Seoul, Kyeonggi-do, Daegu and Kyungpook regions. For analysis of data from 478 respondents, descriptive statistics, factor analysis, cluster analysis, Cronbach's ${\alpha}$, ANOVA, Duncan test and ${\chi}^2$ test were applied. We show the following results: First, factor analysis for appearance management motives extracted three factors such as self-development, emphasis on the trendy appearance, and sexual appealing motive. Factor analysis for appearance management behaviors extracted four factors such as weight training, surgery/skin care, hair care and clothing selection. Second, three groups of the appearance management motives were classified into such as the social self-management type, the sexual appealing self-management type, the passive appearance management type. The social self-management groups are more interested in self-development, emphasis on the trendy appearance, and sexual appealing motive. And they are also more involved in appearance management behaviors: clothing selection is the most pursuing appearance management behavior. Third, among the demographic variables, the single and female in 20s and 30s with higher level of education belonged to the social self-management group. In this contribution, we find significant differences in the appearance management behavior and demographic variables classified by the appearance management motives.

Characterizing local chicken types and their mostly rural production systems is prerequisite for designing and implementing development and conservation programs. This study evaluated the management practices of small-scale chicken keepers and the phenotypic and production traits of their chickens in Oman, where conservation programs for local livestock breeds have currently started. Free-range scavenging was the dominant production system, and logistic regression analysis showed that socio-economic factors such as training in poultry keeping, household income, income from farming and gender of chicken owners influenced feeding, housing, and health care practices (p<0.05). A large variation in plumage and shank colors, comb types and other phenotypic traits within and between Omani chicken populations were observed. Male and female body weight differed (p<0.05), being $1.3{\pm}0.65$ kg and $1.1{\pm}0.86$ kg respectively. Flock size averaged $22{\pm}7.7$ birds per household with 4.8 hens per cock. Clutch size was $12.3{\pm}2.85$ and annual production $64.5{\pm}2.85$ eggs per hen. Egg hatchability averaged $88{\pm}6.0%$ and annual chicken mortality across all age and sex categories was $16{\pm}1.4%$. The strong involvement of women in chicken keeping makes them key stakeholders in future development and conservation programs, but the latter should be preceded by a comprehensive study of the genetic diversity of the Omani chicken populations.

Purpose: This study was done to determine the effects of walking exercise training(WET) on metabolic syndrome risk factors and body composition in obese middle school girls. Method: A non-equivalent pretest-posttest experimental design was used. Twenty seven subjects participated in this study from one women's middle school in Busan. The participants were purposely allocated to an experimental group (n=14) and a control group (n=13). The experimental group participated in 30-60 minutes of WET with 55 to $75\%$ of a maximal heart rate six days a week for 12 weeks. Results: The prevalence of individual risk factors on metabolic syndrome were improved in the experimental group after the intervention. The high waist circumference(WC), high triglyceride(TG), low high density lipoprotein cholesterol(HDL-C), high blood pressure(BP) and high fasting glucose(FG) were 21.4, 21.4, 14.3, 28.6 and $7.2\%$, respectively. There were significant differences in WC (F=22.24, p<.001), TG (F=5.34, p=0.30), body weight(F=21.99, p<.001), fat mass(F=19.17, p<.001), and $\%$ body fat(F=17.93, p<.001) between the experimental and control group after the intervention. However, there were no significant differences in HDL-C, FG and BP between the experimental and control group after the intervention. Conclusion: These results indicate that WET is effective in decreasing risk factors of the metabolic syndrome and body composition components in obese middle school girls. These findings suggest that WET can be useful as a nursing intervention in the prevention of obesity-related disorders in obese adolescents.

Objective: This study collected data on muscle fatigue and ground reaction force during walking to provide a basis for development of custom-fitted outdoor walking shoes. The study analyzed an upright body exercise program using spine stabilization technique to determine the effect on foot plantar pressure in archers, demonstrate the effectiveness of upright body exercise, and develop a new, effective, and efficient training program. Method: A 12-week upright body exercise program was evaluated for the effect on plantar pressure in archers. Ten prize-winning archers (3 men, 7 women) in B metropolitan city, each with ${\geq}10years$ of experience, were given an explanation of the content and purpose of the program, and provided informed consent. Upright body exercise was performed 3 times a week for 12 weeks. A resistive pressure sensor was used to measure foot plantar pressure distribution and analyze quantitative information on variation in postural stability and weight shifting in dynamic balance during shooting, as well as plantar pressure in static balance with the eyes open and closed. Results: There were no significant differences in foot plantar pressure before and after participation in the exercise program. There was no statistically significant difference in foot plantar pressure in static balance with the eyes open or closed, or in foot plantar pressure in dynamic balance during shooting. Conclusion: An upright body exercise program had positive effects on foot plantar pressure in static and dynamic balance in archers by reducing body sway and physical imbalance during shooting and with eyes closed. This program is expected to help archers improve their posture and psychological state, and thereby improve performance.
