This study was designed to identify the relation between health beliefs and compliance with weight control behavior in obese high school students living in Chonnam province. The data were collected from May 24 to 29, 1999. The instruments used in this study were modified by the authors on the basis of the results of the study's related references. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's Correlation using the SAS PC+ program. The results were as follows : 1. The correlation between health concern and compliance with weight control behavior was revealed as statistically significant (r= .34, p= .005). From the correlation of variables, it is concluded that there were statistically significant relations between health concern and benefit (r= .25, p= .043), between health concern and barrier (r= .33, p= .008), between susceptibility and severity (r= .64, p= .000), between susceptibility and benefit (r= .42, p= .000), between susceptibility and barrier (r= .44, p= .003), between severity and benefit (r= .37, p= .002), between severity and barrier (r= .56, p= .000), and between benefit and barrier (r= .38, p= .002). Thus, perceived susceptibility, perceived severity, perceived benefit, and perceived barrier had an indirect influence on compliance with weight control behavior. 2. In the analysis of the relationship between general characteristics and compliance with weight control behavior and health belief variables: Sex (t=2.56, p= .010) was revealed as the influencing variable of health concern. The number of those subjects living together (F=2.88, p= .044) was revealed as the influencing variable of susceptibility. Sex (t=3.47, p= .047), income (F=1.67, p= .051) was revealed as the influencing variable of barrier. 3. In the analysis of the relationship between obese characteristics and compliance with weight control behavior and health belief variables: Perception of weight (F=9.21, p= .000), family history of obesity (t=4.89, p= 030), environment of obesity (t=14.30, p= .000) were revealed as the influencing variables of susceptibility. Perception of weight (F=4.86, p= .001), symptoms of obesity (t=4.46, p= .006), family history of obesity (t=6.59, p= .012), environment of obesity (11.30, p= .001), and reasons of weight control (F=3.07, p= .010) were revealed as the influencing variables of severity. Symptoms of obesity (F=4.15, p= .009), reasons of weight control (F=2.41, p= .046) were revealed as the influencing variables of benefit. Environments of obesity (t=4.23, p= .044) were revealed as influencing variables of barrier. These results suggest that for improvement in compliance with weight control behavior, school nurses should stimulate the students' concerns about health.

To know the impact of female pupal weight corresponding to the male cocoon shell weight upon fecundity, hatchability and percentage of non-viable eggs, the experimental multivoltine breeds namely BL67 and 96A were categorised into low, medium and high batches according to the weight of female pupae and male cocoon shells and moths emerged from low, medium and high female pupae were allowed to mate withmoths emerged from low, medium and high male cocoon shells. Both the experimental breeds of BL67 and 96A revealed a fairl trend in fecundity for high batch ＞ medium batch ＞ low batch. When data were statistically analysed, a significant (p ＜ 0.05) and a highly significant (p ＜ 0.01) increase in fecundity was observed in the medium and high batches of BL67 during November - December, 2002 whereas highly significant (p ＜ 0.01) increase was observed in the high batches of 96A during November - December, 2002. Data revealed a highly significant (p ＜ 0.01) increase in fecundity in medium and high batches of both the breeds during January - February, 2003. More interestingly, a significant (p ＜ 0.05) reduction was noted in percentage of non-viable eggs in high batches of 96A during January - February, 2003. But no significant variation in hatchability was noticed due to the effect of differential female pupal weight and male cocoon shell weight.

This study was done to investigate the relationship between the perception of body image, body weight satisfaction or dietary behavior and self-rated health status in Korean college students. Subjects, 285 college students, were divided into three groups (healthy, normal, and unhealthy) according to the answer for the self-rated health question. Information about demographic status, self-rated health condition, height and weight, perception of body image, satisfaction of body weight, concern for body weight control, dietary behavior, nutritional knowledge, and health-related characteristics collected by a self-reported questionnaire. The proportion of men and women in each group was not significantly different. The academic year, major, experience of nutritional education, and type of residence were not significantly related with self-rated health but the pocket money range was significantly associated (p<0.05) with self-rated health. The proportion of subjects rated their health as unhealthy was the lowest in 210-300 thousand won pocket money range and was increased in less than 210 thousand won or over 300 thousand won pocket money ranges. There were no significant differences for age, height, weight and BMI between the groups. The body image perception and body weight satisfaction levels of healthy group was significantly higher than those of unhealthy group (p<0.01 and p<0.001, respectively), but the level of concern for body weigh1 control in healthy subjects was significantly lower than that in unhealthy subjects (p<0.05). The proportion of subjects reported as healthy was significantly increased with increased frequencies of following food behaviors; weekly use of protein foods (p<0.01), vegetables (p<0.05) and dairy products (p<0.01), and food habits such as "regularity of meal time" (p<0.01), "eating in moderation" (p<0.05), and "eating breakfast" (p<0.001). Overall results suggested that the college students have tended to have a better perception of health when they have better body image perception, body weight satisfaction and dietary behaviors.

This study was performed to investigate the effectiveness of nutrition education and exercise intervention in a weight management program. The subjects were 24 obese women whose body mass index (BMI) was over $25kg/m^2$. Nutrition education was given once a week, and subjects did swimming three times a week. The program lasted for 12 weeks. Nutrient intakes were assessed by 24 hour recall method. Also food habits, dietary behavior and nutrition knowledge were examined by self-administered questionnaires before and after the weight control program. Height, weight, body composition and blood composition were measured before and after the weight control program. Over the 12 weeks in the weight control program, body weight significantly decreased from 69.7kg to 65.8kg(p<0.001). Body fat and BMI also significantly decreased(p<0.001). Cholesterol level significantly decreased at p<0.001 and blood sugar also significantly decreased (p<0.05). After taking nutrition education, dietary behavior and nutritional knowledge scores increased, energy intakes decreased from 1426.5kcal to 1408.5kcal and calcium from animal products significantly increased(p<0.05). A negative correlation between nutrition knowledge and BMI(r=-0.42) existed(p<0.05). A negative correlation of eating behavior with EER(r=-0.48) showed(p<0.05). We concluded that combined nutrition education and exercise was an optimal method for reducing weight.

Purpose: The purpose of this study was to determine the effects of a weight loss program administered through a smart phone application on body composition and obesity in adolescents. Methods: This study applied a 6-week weight loss program with dietary education, exercise therapy, and behavior modification therapy from 4 June 2012 to 20 July 2012. The collected data were analyzed by descriptive statistics and the Wilcoxon signed rank test using the SPSS WIN 18.0 program. Results: After the 6-week program, the average weight of the subjects was reduced from 75.96kg to 74.41kg (Z=$-3.994^p$, p<.001), while the body mass index (BMI) decreased from 29.23 to 28.60 (Z=$-3.980^p$, p<.001), and the obesity index decreased from 38.45% to 35.59% (Z=$-3.977^p$, p<.001). The percentage of body fat decreased from 32.45 to 31.92 (Z=$-3.947^p$, p<.001), and the rate of skeletal muscle growth increased from 26.06% to 26.58% (Z=$-3.822^p$, p<.001). Conclusion: A weight loss program using a SNS (social network service) application, with dietary education, exercise therapy, and behavior modification therapy can reduce obesity and impact body composition in a short-term. Therefore, the utilization of the SNS application can be used to effectively enhance the management of adolescent obesity.

Tropical tasar silkworm, Antheraea mylitta is a commercial forest silkworm in India that produces tasar silk, but never experimented in Uttarakhand, a Himalayan state of India. A. mylitta express divergent phenotypic characters under different ecological conditions; so, we studied the effect of seven forest tree species in two rearing seasons on variability in silk gland weight of Daba (bivoltine) ecorace of A. mylitta at Forest Research Institute in Dehra Dun, Uttarakhand during 2012 and 2013. We used two-way completely randomized block factorial design and Post HOC Tukey's HSD test to analyse the collected data and there after carried out multiple regression analysis. Results indicated that silk gland weight differed significantly between rearing seasons (DF=1, F=2333.98, p <0.05), host plants (DF 6, F= 1516.25, p <0.05) and their interactions (DF=6, F=7.10, p <0.05). Higher silk gland weight was found in second rearing season than the first on all the host tree species. Terminalia alata fed A. mylitta larvae showed the highest silk gland weight of 8.03 and 9.47 g in first and second rearing seasons, followed by T. tomentosa (7.19 & 9.01g), T. arjuna (6.8 & 8.08 g) and L. speciosa (6.57 & 7.83 g) fed larvae, respectively. Post HOC Tukey's HSD test indicated that silk gland weight of L. speciosa and T. arjuna fed larvae in both the rearing seasons did not differ significantly. E.I. analysis also confirmed that T. alata, T. tomentosa, T. arjuna and L. speciosa are better in their order of merit than T. bellirica , T. chebula and L. tomentosa. Multiple regression analysis indicates that larval weight gain is a strong predictor (β=1.002, t=346.777, p = <0.05) for the silk gland weight of A. mylitta ; however, larval duration had significant negative regression weight (β=-0.270, t=-8.436, p = <0.05) on mean weight of silk gland.

Influences of clotrimazole on the blood cholesterol and HDL-cholesterol level were studied in rats. Rats were provided food and water ad libitum and clotrimazole and methylcellulose were gavaged for 6 days. Clotrimazole was suspended in 1% methylcellulose solution as and administered at concentration 20mg/Kg, 40mg/Kg, 60mg/Kg. Body weight gain and liver weight/body weight ratio, serum cholesterol level, serum HDL-cholesterol level, serum triglyceride level, the activity of cytochrome p450 and erythromycin demethylase were determined at 6th day. Clotrimazole decreased the body weight gain a little as compared with control group and did not show any influence on liver weight/body weight ratio. Clotrimazole increased the serum HDL-cholesterol and serum triglyceride level significantly. Clotrimazole increased the microsomal cytochrome P450 significantly and increased the erythromycin demethylase (cytochrome P450 IIIA) significantly too. It might be conclued that clotrimazole showed a little influence on body weight and increased the serum lipid, especially HDL-cholesterol level. It also increased microsomal cytochrome P450 IIIA significantly. It might be concluded that clotrimazole showed a corelative influence between HDL-cholesterol and cytochrome P450 IIIA. In these results clotrimazole can be used as an anti-atherosclerotic agent by increasing the HDL-cholesterol but it is necessary that cloreimazole will show any adverse or side action on body or not.

This study was conducted to identify factors influencing the weight control behavior of college students. The subjects included college students in the C area, and data were collected through a self reported structured questionnaire from Dec 01 to 20 of 2015. Overall, 289 subjects were analyzed. Analyses consisted of descriptive statistics, t-tests, ANOVA, Pearson's correlation analysis, and stepwise multiple regression analysis. The findings showed a prominent distortion of college students' perceptions of their bodies based on evaluation by others and obesity stress, which had special impacts on their weight control behavior. Weight control behavior, body self-awareness (r=.31, p<0.001), assessment of body by others (r=.30, p<0.001), and obesity stress (r=.43, p<0.001) were closely related to their weight control behavior. Stepwise multiple regression revealed that their weight control behavior was closely influenced by obesity stress (${\beta}=.37$, p<0.001) and assessment of body by others (${\beta}=.15$, p=0.009). These variables accounted for 20% of the weight control behavior (F=37.30, p<0.001). Overall, assessment of body by others and obesity stress were found to be predictors of their weight control behavior. These findings indicate that it is necessary to develop and implement information programs and design appropriate prevention programs that can induce healthy weight control behaviors. Such programs should include health education, as well as intervention programs to identify such predictors and help college students judge and perceive their body shapes objectively so that they control their weight in a proper manner.

Purpose: This study examined the effects of the weight-bearing pattern and calcaneal taping on the heel width and plantar pressure in standing. Methods: Fifteen healthy subjects with normal feet participated in this study. The heel width was measured using a digital caliper, and a pedoscan was used to measure the plantar pressure of the rear foot while standing. The participants were instructed to stand in three weight-bearing patterns (anterior, middle, and posterior weight bearing) before and after calcaneal taping. The heel width and plantar pressure were measured three times before and three times after calcaneal taping, with the three weight-bearing patterns applied in random order. A 2 (non-taping vs. taping) × 3 (anterior, middle, posterior weight bearing) two-way repeated ANOVA with a Bonferroni post hoc correction was used to assess the differences in heel width and plantar pressure. Results: The results revealed a significant main effect of the weight-bearing pattern (p<.01), but not of calcaneal taping (p>.05). Greater weight bearing applied to the heel resulted in a significantly increased heel width and planter pressure of the rear foot (p<.01). Conclusion: In standing, a posterior weight-bearing pattern increases the heel width due to side-to-side shifting of the plantar heel pad, which increases the heel plantar pressure. Therefore, to prevent high stress on the heel pad and plantar heel pain, it is important to refrain from posterior weight bearing while standing during the activities of daily living.

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.
