The purpose of this study was to determine the body weight control, food habits and nutrient intakes according to the obese index in male middle school students. This study was carried out through questionnaires and measurement by body fat analyzer (Inbody 4.0). The subjects were 275 male middle school students in Iksan. Chonbuk province. The average age, height, weight, and BMI of the subjects were 14.4 years old, 167.8 cm, 60.2 kg and $21.3kg/m^2$, respectively. Seventeen point one percent of the subjects were the underweight group, 47.6% were the normalweight group, and 35.3% were the overweight group by the classification of the Korean Pediatrics Society standard. Body fat of underweight, normalweight, and overweight were 16.1%, 19.0%, and 26.6%, respectively. Thirty one point nine percent of underweight, 39.7% of normalweight. and 31.9% of overweight had misperceptions of their weight (p<0.001). Sixty two point two percent of the males were dissatisfied with their body weight, and 55.3% of the whole tried to reduce their body weights. Even though they were normalweight, half of them dissatisfied with their weight. The source of weight control method was friends and family, TV radio, Internet, and school nutrition education, in order. The subjects exercised 3.4 days per week, 70.2 minutes per day, but it was not different significantly by the obese index. Forty percent of the subjects had meals fast, 58.5% of them have biased food habits even if they didn't differ by the obese index. Activity rate was different by the obese index significantly (p < 0.05), the number of severe activity was most in underweight. In conclusion, nutrition education programs should contain the necessity of normalweight, and regularity of lift habits and activities for energy expenditure in overweight students. It made them to recognize their weight correctly, establish healthy body images, and raise the ability to promote health and improve nutritional status.

This study aimed to find the differences in weight control status and eating behavior of satisfied and dissatisfied female high school students regarding their own body shape. The participants consisted of 238 students at two female high schools in Nonsan-si, Chungnam-do in May of 2008. Self-assessment evaluated present body shape and ideal body shape they would like to have by providing silhouette drawings. The subjects were divided into two groups, 'satisfied' and 'dissatisfied', according to the differences between present body shape and ideal body shape. In the distribution of subjects according to body mass index, 100% of overweight, 97.0% of normal weight and 48.7% of underweight belonged to the dissatisfied group. There were significant differences in weight control and eating behavior between dissatisfied and satisfied groups in terms of frequency and reasons of conducting weight control behavior, body weight return after weight reduction, skipping breakfast and consuming fast food. The satisfied group was two times more likely to not conduct weight control behaviors compared to the dissatisfied group. The main reason for trying to control weight differed according to the group; the reason was feeling fat in the dissatisfied group and desiring to be healthy in the satisfied group. The percentage of subjects that returned to their original weights after weight reduction was 5 times higher in the dissatisfied group. The percentages of subjects that regularly skip breakfast and consume fast food were both higher in the dissatisfied group than in the satisfied group. The dissatisfied group responded 'eating alone' more frequently among nine binge eating behaviors compared to the satisfied group. Both groups, however, did not show any difference in overeating of meals, eating speed, intake frequency of regular meals, food preference, preferred cooking method, carbonated beverage intake and snack eating behavior. In summary, the dissatisfied group tried more unnecessary body weight reduction and had poor eating behavior. Accordingly, to correct the biased perception of body shape by the majority of female high school students, the values of our society should change toward the pursuit of beauty of health.

Body water compartments in vivo were determined in Holstein cattle with age ranging from 5 to 521 days to obtain an equation to estimate volumes of body water. Live weight ranged from 47 to 480 kg. Compartments were determined as antipyrine space for total body water (TBW), thiocyanate space for extracellular water (ECW) and Evans blue dye space for plasma water (PW). Body water compartments expressed as a percentage of live weight decreased as age in days increased and significantly correlated with age in days. Regression analyses revealed that prediction equations had low accuracy. Regression equations of body water compartments on live weight (WT, kg) were useful for the prediction of body fluid with a high accuracy. Live weight significantly regressed on age in days (Day), which was inferred to be utilized for estimation of standardized live weight in case animals were emaciated by certain causes such as severe diarrhea or dehydration. In conclusion, following equations were presented to estimate body water compartments of cattle in vivo : TBW in liters = $0.556({\pm}0.007)WT+10$, r = 0.993, $SE{\pm}0.7$ ECW in liters = $0.321({\pm}0.008)WT+10$, r = 0.978, $SE{\pm}0.8$ PW in liters = $0.0502({\pm}0.0012)WT+1.6$, r = 0.0983, $SE{\pm}0.1$ WT (kg) = $0.772({\pm}0.018)Day+24$, r = 0.982, $SE{\pm}2.3$.

A major aim of cattle genome research is to identify candidate genes associated with meat quantity and quality through QTL analysis for application in the livestock industry. Therefore, this study focused on discovery of useful SNPs within the LOC534614 gene, containing 12273_165 SNP which is located on the same site as the QTL on chromosome 6, and evaluation of the association between SNP and body weight and cold carcass weight in Hanwoo (Korean cattle) As a result of a BLAST search of the NCBI web site, we discovered that the mRNA sequence of the LOC534614 gene was similar to that of the coiled-coil domain containing 158 (CCDC158) for dog and human. According to the direct DNA sequence from the CCDC158 gene, we identified 19 polymorphic SNPs within exons and their flanking regions. Among them, 17 polymorphic SNPs were selected for genotyping in Hanwoo (n = 476) and seventeen marker haplotypes containing 12273_165 SNP (frequency >0.1) were identified. As a result of the association between 17 polymorphic SNPs and Hanwoo (n = 476), g.8778G>A SNP in exon 6 was found to be a non-synonymous SNP, and was significantly associated with body weight and cold carcass weight (p<0.05). We discovered 19 polymorphic SNPs in the CCDC158 gene on the QTL region of BTA 6 in Hanwoo and identified that the g.8778G>A SNP was significantly associated with body weight and cold carcass weight (p<0.05), which causes an amino acid variation from valine to methionine. Furthermore, statistical analysis demonstrated that the CCDC158 gene is strongly associated with body weight and cold carcass weight in Hanwoo. In this regard, the g.8778G>A SNP in the CCDC158 gene can be useful as a positional candidate for body weight and cold carcass weight for marker-assisted selection in Hanwoo.

This study was conducted to estimate the growth curve parameters for the body weight (BW) and body length (BL) of miniature pigs in Korea. Growth curve parameters were estimated through a nonlinear regression model using Gompertz, Logistic, and von Bertalanffy methods. A total of 25 piglets were measured monthly from birth up to 15 months of age to estimate both body weight and length. Results showed that the estimated average values for the body weight (body length) were 31.83 kg (58.77 cm) for the mature weight (A), 3.06 (1.74) for the growth ratio (${\beta}$), and 0.28 (0.52) for the maturing rate (${\kappa}$). Average inflection points showing maximum growth rate estimated each month for body weight were 3.97 kg and 11.70 cm, while for the body length were 1.06 kg and 21.61 cm. Moreover, the estimated maturation rates of the body weight and length for the group of Sire 1 were 0.22 and 0.40 respectively, whereas for the group of Sire 2 these values were 0.34 and 0.39. On the other hand, for the groups of Dam 1, Dam 2, and Dam 3, maturation rates for their body weights were 0.26, 0.28 and 0.33 respectively, while for their body lengths these values were 0.43, 0.37, and 0.38, respectively. The study also indicated a negative relationship between the values of mature weight and maturity rate for the body weight will result to a higher inflection point which is in contrast for the body length where results show that a positive relationship between the values of mature length and the maturity rate will result to a higher inflection point. Furthermore, the growth performance of miniature pig varies across stages but using these estimated growth curve parameters could improve the genetic traits of miniature pig.

The purpose of this study is to examine the influence of sociocultural attitudes toward appearance and narcissism on body stress. Questionnaires are being administered to 206 women in their 20's-50's living in Deagu and Kyunbook province. The Frequency, factor analysis, reliability analysis, correlation analysis, regression analysis, ANOVA, and Duncan-test are used for data analysis. Sociocultural attitudes toward appearance are categorized into media appearance internalization and social recognition of appearance. Narcissism factors are found to be leadership/privilege, ostentation, and superiority. Body stress is categorized into 4 factors: weight stress, skin aging stress, body dissatisfaction, and hair stress. Sociocultural attitudes toward appearance was related to the sub-variables of narcissism, and body stress. Media appearance internalization is the sun-variable of sociocultural attitudes toward appearance and has significant effects on weight stress, skin aging stress, and body dissatisfaction sub-variables for body stress. Ostentation, and superiority being the sub-variables of narcissism, have significant effects on weight stress, skin aging stress, body dissatisfaction, and hair stress, the sub-variables for body stress. Ages of women display distinctions between the sub-variables in sociocultural attitudes toward appearance such media appearance internalization, and in narcissism such leadership/privilege, ostentation, superiority, and body stress such weight stress, skin aging stress, body dissatisfaction, and hair stress. This result can be a necessary base line data for adult women's appearance management by examining the influence of the attitude toward the appearance developed from the relationship with people around body stress.

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.

Acute and subacute toxicity of Artemisia asistica Nakai Aqua-acupuncture Solution (ANAS) were studied in ICR mice. In acute toxicity test, mice were injected intraperitoneally with single dose of $1{\times}$, $5{\times}$, $10{\times}$ ANAS, and toxicological responeses were observed for consecutive 14 days. Mortality, body weight changes, organ weight, and serum chemistry were performed. The mortality and body weight changes of mice treated with $1{\times}$ and $5{\times}$ ANAS were not affected during the experimental periods. With the $10{\times}$ ANAS treatment, there were dead animals and changes of body weight, organ weight and serum biochemical values were observed during the experimental period. In subacute toxicity test, mice were injected intraperitoneally with doses of $1{\times}$, $10{\times}$ ANAS for 14 days. No difference was found between control and $1{\times}$ ANAS treated group in mortality, changes of body weight and organ weight, and serum biochemical values. However, Dead animals, changes of body weight and organ weight, and increased serum biochemical values were observed with $10{\times}$ ANAS treated groups. These results suggest that $1{\times}$ ANAS causes no toxicity in acute and subacute toxicity tests. However $10{\times}$ ANAS causes toxicity in both tests.

The purpose of this study was to evaluate weight control program provided by university health care center for female college students. The program was 8-week long and composed of diet, exercise, and behavioral modification. Evaluation was made on the completion of 8-week program and a follow-up survey was done at 3-24 months after the end of program by telephone or bye-mail. Total of 76 women completed the 8-week program and 51 for follow-up survey. On the completion of 8-week program, significant decreases in body weight, BMI, body fat (kg), ％ body fat, and WHR were resulted, however, no change in muscle mass was found. Even the subjects without weight change showed significant reduction in body fat (kg) and ％ body fat. Total food intake was decreased resulting in reduced intakes of most nutrients. Meal distribution of energy was changed; ％energy from snack decreased from 22％ to 14％, and proportion for breakfast increased. Blood values of hemoglobin, hematocrit, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride were within normal range, and no changes were observed by this program. The follow-up survey revealed that 88.3％ of the subjects continued to lose weight after completion of the program, while only 7.8％ gained weight. And 78.4％ of the subjects considered the program effective. In conclusion, the weight reducing regime with education is effective for long lasting weight control and health conscious behavior for female college student. Since the subjects reduced the size of meal, instead of cutting only calories down, food selection to meet all the nutrient requirements except energy should be emphasized.
