We present construction methods for free self-orthogonal (self-dual or Type II) codes over ℤ₄[v]/〈v² + 2v〉 which is one of the finite commutative local non-chain Frobenius rings of order 16. By considering their Gray images on ℤ₄, we give a construct method for a code over ℤ₄. We have some new and optimal codes over ℤ₄ with respect to the minimum Lee weight or minimum Euclidean weight.

This study was performed to provide sources of nutrition education for female adolescents by identifying eating disorder patterns and their relationships with self-body image, weight control, and eating behavior. A total of 329 female middle school students were recruited and completed a general characteristics survey, the Eating Attitudes Test(EAT-26), a perception of self-body image survey, a concern for weight control survey, an eating behavior survey, and the Mini Dietary Assessment Index(MDA). Eating disorder patterns were identified to be obesity stress and weight control(OW), risk of binge eating(RB), and dietary restraint(DR) by factor analysis. OW pattern was related with stout body shape, body dissatisfaction, experience of weight control, skipping of dinner, and low MDA score. RB pattern was associated with lean body shape, body satisfaction, indiscreet snack behavior, and the eating time of snacks. The DR pattern was associated with normal body shape, regular meal times, desirable snack behavior, and high MDA scores. The results indicated that the eating patterns of adolescent were not identical to existing diagnostic categories. Furthermore, each eating pattern displayed different characteristics of perception on self-body image, concern for weight control, and eating behavior. In conclusion, nutrition education for female middle school students could reflect the different characteristics of each eating disorder pattern.

The study purpose was to examine weight control status and related factors among 370 high school girls in Seoul. Factors examined included interest toward weight control, body satisfaction, body image, beliefs regarding weight control and self-efficacy. $65.1\%$ had attempted to control weight and were categorized into attempt group. Those in the attempt group had higher body weight (p < 0.001) and BMI (p < 0.001) than the counterparts. They tried to control weight 2.9 times on average (22.4 days each time). The major information sources for weight control were internet ($62.8\%$), and TV/radio ($17.1\%$). Exercise was most commonly used for weight control, followed by reducing meal amount and skipping dinner. The attempt group was less satisfied with body size (p < 0.001) and perceived their body size as heavier than the counterparts (p < 0.001), but they showed more interest toward weight control (p < 0.001). The ideal body size of society or the body size that they want was very thin in both groups. Twelve out of 20 beliefs regarding weight control were significantly different between the two groups. The attempt group believed more strongly on the advantages such as increased self-confidence, appearance, attractiveness (p < 0.001) and 'good for making friends' (p < 0.01) In contrast, the attempt group believed less strongly about the disadvantages including harmful effects on health (p < 0.001), parents' dislike, feelings of discouragement (p < 0.01) and becoming (p < 0.05). The attempt group showed lower overall self-efficacy to control overeating (p < 0.05) than the counterparts. Especially, the attempt group felt less control of overeating in situations such as eating-out, after school, when they are with family (p < 0.01) or with friends, when they feel hungry, during examination periods and when others offer food (p < 0.05). This study suggested that weight management education for adolescents include strategies for changing body image and beliefs regarding weight control, as well as increasing self-efficacy to control overeating.

The purpose of this study was to classify appearance management attitudes into groups and analyze the difference of self-efficacy and body satisfaction by the groups. Questionnaires were administered to 255 college students living in Deagu Metropolitan City and Kyungbook province. The data collected were analyzed by using frequency, factor analysis, cluster analysis, correlation analysis, ANOVA, Duncan-test, t-test, and ${\chi}^2$-test. The findings were as follows. Appearance management attitudes of college students were classified into three groups such as group health body, low body interest group, emphasizes collective body. The appearance management attitudes showed significant correlation with the sub-variables of self-efficacy and body satisfaction. Male students showed no significant difference in self-efficacy by the groups while female students showed a significant one in task performance which was a sub-variable of self-efficacy. Both of the male and female students showed a significance of difference in the gap between actual and ideal weight which was a sub-variable of body satisfaction by the groups. Gender of college students showed distinction between the sub-variables of self-efficacy factors such as task performance, and anxiety and body satisfaction such as BMI, the difference between current height and ideal height, the difference between current weight and ideal weight.

The purpose of this study was to investigate the effects of narcissistic personality and self-esteem on the appearance management behaviors(weight, skin care, makeup, hair care, clothing selection) of female college students. The questionnaires were administrated to 362 female college students living in Gwang-ju city, Korea. For analysis of data, descriptive statistics, factor analysis, Cronbach'$\alpha$, regression analysis were applied. The results were summarized as follows. First. the female college students' narcissistic personality was categorized into four factors, need for administration, leadership/self-confidence, need for power/entitlement, and superiority. Second, narcissistic personality significantly influenced appearance management behaviors. The further examination of the effects showed that need for administration appeared to affect clothing selection, hair care, skin care, makeup, and weight. Third, self-esteem turned out to have positive effects on overall appearance management behaviors. The further examination of the effects showed that self-esteem appeared to affect clothing selection, skin care, hair care, makeup, and weight. The results indicated that female college students' narcissistic personality and self-esteem were important factors to their appearance management behaviors and marketing programs for fashion industries.

Purpose: This study examined the effects of self-volar gliding combined with a strap and wrist distraction on pain and the active and passive wrist extension range of motion (ROM) in subjects with dorsal wrist pain during partial weight bearing of the hand. Methods: Thirty subjects (14 males and 16 females) with dorsal wrist pain during partial weight bearing through the hand participated in this study. The two different self-volar gliding techniques were performed for each group. Self-volar gliding using a strap (SVGS) and SVGS and wrist distraction (SVGSD) were performed five times for one week for each group. The active and passive ROM of wrist extension and the peak pressure pushed by the hand at pain (PPHP) were measured. An independent t-test was used to compare the improvements of these elements between the two different self-volar gliding techniques. The level of statistical significance was at ${\alpha}=0.05$. Results: The active and passive ROM of wrist extension and PPHP were greater in both self-volar gliding groups after the one week intervention. On the other hand, these parameters were greater in the SVGSD group than in the SVGS group (p<0.05) Conclusion: SVGSD is recommended to improve the active and passive ROM of wrist extension and PPHP in subjects with dorsal wrist pain during partial weight bearing of the hand.

The purpose of this study is to investigate the relationship between eating disorders, body image, and self-esteem of high school girls. Data were analysed by SPSS/PC using frequency, percentage, mean, standard deviation, ANOVA, & Pearson correlation coefficient. The results of this study are as follows. 1. The mean of body weight and height of the subjects were 52.49kg, 161.16cm. As defined by BMI, the obese subjects were very rare(2.1%) and the rest(97.9%) was under weight or normal. 2. More than 53% of the subjects perceived their weight as overweight, while 2.1% of the women were obese as defined by BMI. Ninety-three percent of the subjects were not satisfied with their body shape. 3. For the need for weight control, subject's own judgement(70.8%) was the highest percentage. High percentages of the women reported a decrease in the amount of eating(22.9%), and an increase in the amount of exercise(52.8%) as effective methods of weight control. 4. The total mean score of anorexia nervosa was higher than bulimia nervosa. 5. The scores of eating disorders did not differ significantly by the BMI score : The score of eating disorders was highest in the group os the overweight. 6. The score s of body image did not differ significantly by the BMI score : The score of body image was highest in the group of the overweight. 7. No significant difference was found in over all self esteem scores according to the BMI scores. 8. There was high positive correlation between BMI and eating disorders(r=.2158, p=.0094), between self-esteem and body image(r=.4288, p=.0001), and positive correlation between BMI and self-esteem(r=.1569, p=.0604), and between BMI and body image(r=.1354, p=.1056).

In earthwork projects, the designer considers cut and fill balance for minimizing earthwork which may significantly decrease construction costs. Despite carrying out considerable earthwork design, the decrease in volume of earth occurs in construction sites because of embankment settlement under self-weight, consolidation settlement of soft ground, cavity filling and soil loss due to rainfall-runoff. To reflect the decrease in volume of earth, the specifications for road construction just give shrinkage factors in embankment for soils without consideration of embankment settlement under self-weight. In this study, the computational method is used to estimate the amount of embankment settlement under self-weight developed by Iseda (1972) and Ishii (1976). This research shows that the total compression settlements are between 3 to 10 percent of embankment height according to the property of embankment material and embankment height. As a result, the designer should consider the compression settlement on embankment material under selt-weight.

The aim of this study was to determine the association between the Body Mass Index (BMI), weight perception and depression-like symptoms in Korean middle school students. The data was obtained from the 2012 Korea Youth Risk Behavior Web-based Survey. The subjects were 37,297 students living in the community. Adjusting for covariates (sex, school year, home economics, city-type, school record, self-reported happiness, self-reported health status, suicidal thinking, smoking, alcohol consumption), the self-reported obesity (OR=1.14, 95% CI: 1.06-1.22) and self-reported underweight (OR=1.11, 95% CI: 1.03-1.20), compared to the self-reported healthy weight, were more likely to have depression-like symptoms. On the other hand, the BMI-based weight was not associated independently with depression-like symptoms. These findings suggest that weight perception is significantly associated with depression-like symptoms.
