  • The dredged soils of western sea of Korea have been used as the fill materials because it possess the characteristics that constitute silt, silty sand and sand mainly. However, a study on dredged soils as the fill materials is insufficient. Hence, in this present study, the application the dredged soils of western sea of Korea as the fill materials was confirmed. Primary, the composition characteristics of the ground was analyzed to confirm the application on dredged soils as the fill materials by the piezo-cone penetration test. In laboratory test, it was performed the self-weight consolidation test for mechanical characteristics of the dredged soils. The direct shear test using self-weight consolidation test sample for shear strength characteristics was performed after self-weight consolidation test. Additionally, the mechanical characteristics of the dredged soils on elapsed time using self-weight consolidation test sample, which is drained naturally, was evaluated. The dredged soils of western sea of Korea show that unit weight and shear strength is increased as natural drain time elapses.

  • The purpose of this study is to develop and evaluate the Self Efficacy Promotion and Exercise Program to prevent of obesity and cardiovascular diseases for the kidney transplant recipients. The subjects were selected randomly among the patients who underwent kidney transplantations at one major transplantation hospital in Seoul, Korea. This study ws carried out between November 23, 1999 and February 15, 2000. The subjects in this study consisted of 16 patients who had kidney transplantations between 1 month and 12 months ago prior to this study. They were all on steroids therapy and did not take any physical exercise regularly. The subjects received the self efficacy promotion and exercise program for 12 weeks which contained self efficacy promotion education and exercise program. The weight, body fat rate, exercise time and cardiopulmonary function were evaluated before the experiment and after the experiment. The results were as follows: 1. After the experiment, the weight was significantly decreased than that of before the experiment(p=.0001). 2. After the experiment, the body fat rate was significantly decreased than that of before the experiment(p=.0010). 3. After the experiment, the exercise time was significantly increased than that of before the experiment(p=.0002). 4. After the experiment, the absolute VO2 was significantly increased than that of before the experiment(p=.0008). 5. After the experiment, the relative VO2 was significantly increased than that of before the experiment(p=.0002). This study showed that the self efficacy promotion and exercise program was effective. So it would be expected that this self efficacy promotion and exercise program could be applied as an effective independent nursing intervention widely in prevention of obesity and cardiovascular diseases for kidney transplant recipients.

  • This study classified respondents by degree of obesity using Body Mass Index(BMI) and investigated the differences in self-esteem, food lifestyle, social-cultural attitudes towards appearance, and diet-related attitude and behavior such as trial number of diet, exercise time and period, use of diet information, interest in weight control, diet motivation, and dietetic therapy. A survey was conducted with 258 adults between the ages of 20 and 29 who lived in Daegu and Uijeongbu from November $17^{th}$ to December $14^{th}$ 2014. Data collected from the respondents were analyzed using descriptive statistics, factor analyses, analyses of variance and chi-square tests. This study divided the respondents into three groups (the underweight, the normal weight, the overweight) according to Body Mass Index. The results showed that there were significant differences in food lifestyle (health-conscious, popularity-seeking, taste-seeking), social-cultural attitudes towards appearance, exercise time and period, use of diet information, interest in weight control, diet motivation, and dietetic therapy among groups classified by degree of obesity. However, there were no differences in self-esteem, convenience-seeking, and trial number of diet among them.

  • Purpose: The purpose of this study is to investigate the relationship between eating disorders, body image, and self-esteem of female university students. Methods: A total 123 university female students were recruited in April 2009. Data was collected by using questionnaires. The collected data was analysed by SPSS/WIN using frequency, percentage, mean, standard deviation, ANOVA, & Pearson correlation coefficient. Results: As defined by body mass index (BMI), the obese subjects were rare (8.9%) and the rest (91.1%) was under weight or normal. More than 51.2% of the subjects perceived their weight as overweight, while 8.9% of the women were obese as defined by BMI. Eighty-eight percent of the subjects were not satisfied with their body shape. The total mean score of anorexia nervosa was higher than bulimia nervosa. The scores of eating disorders did not differ significantly by the BMI score. The score of body image was highest in the group of the overweight. There was high positive correlation between self-esteem and body image. Conclusion: To ensure resonable body image and weight control behaviors in female university students, education should be reinforsed. Therefore, nursing intervention programs for cognitive changes correcting the understanding about body image need to be developed.

  • Purpose: The purpose of this study was to investigate the effect of weight control program on body composition(body mass index and waist-hip ratio), blood pressure, serum lipids(total cholesterol, triglyceride, high density lipoprotein and low density lipoprotein) and self-regulation behavior in obese college women. Methods: Forty seven obese subjects were divided into experimental(22) and control(25) groups. The weight control program lasting 12 weeks consisted of a traffic-light diet, jumping-rope exercises, and behavior modification methods with e-mail counseling. The data were collected from 29 March to 17 September of 2004. The variables were assessed before and after intervention for 12 weeks in two groups. Then, those were repeated after a 12 week suspension of intervention in the experimental group. The data were analysed by the SPSS computer program. Results: BMI, HDL, LDL and self-regulation behavior levels showed significant differences between the experimental and control groups. While there were no significant differences in waist-hip ratio, blood pressure, total cholesterol and triglyceride. Conclusion: The weight control program had a positive effect on obese college women, and can be used to control obesity.

  • This research analyzes how female college students' perception of somatotype-self and their satisfactions with their somatotype-self affect their appearance-management behaviors. The result is as follows: 1)An analysis of subjects' physical characteristics revealed that the average figures of their body sizes were within the normal boundaries. The average Quetelet Index of the subjects, which determines obesity of adults, was slightly below the nationwide physical standard of Korea. 2)The subjects' satisfaction with their each body part shows that the women were unsatisfied with every body-part measurement; height, bust size, waist size, hips size and particularly weight. 3)While most of the respondents recognized that sizes of their body parts were average, they were not happy with their body sizes. 4)Three factors were recognized from the study of appearance-management behaviors of the subjects; we defined them as 'Appearance Management', 'Weight Management', and 'Satisfaction with one's Appearance.' The study showed that the fatter, the more a subject controlled her weight. 5)A correlation study between one's perception of her body and her appearance-management behavior found that the more obese a subject was, the harder the subject was controlling her weight.

  • This study was aimed to investigate the relations between self-selected intake of 3 macronutrie-nts and body weight gain and body fat accumulation in male rats given three isocaloric diets differing carbohydrate protein and fat contents concurrently. Also the effect of dietary restriction was observed. Forty two male rats of Sprague-Dawley strain weighing 68.7$\pm$6.1g were randomly divided into 2 groups and were allowed to have foods from 3 different cups for 8-hours a day or ad libitum, After 12 weeksthey were decapitated and their brains were quickly removed and frozen until they were assayed for serotonin and its metabolite 5-HIAA The carcass was dried at 105$\pm$2$^{\circ}C$ and measured the contents of body water and body fat. The animals chose a moderately high and constant carbohydrate level and showed the increase of percent protein intake with age and great individual variations. Protein in the diet seemed to trigger appetite and increase food intake which resulted in higher weight gains and in more fat deposition in the body. The concentration of brain serotonin did not show any correlations with the intake of nutrients. the accumulation of body fat and the gain of body weight.

  • Vertical drains are commonly used to accelerate the consolidation process of soft soils, such as dredged materials, because they additionally provide a radial drainage path in a deep soil deposit. In practice, vertical drains are commonly installed in the process of self-weight consolidation of a dredged soil deposit. The absence of an appropriate analysis tool for this situation makes it substantially difficult to estimate self-weight consolidation behavior considering both vertical and radial drainage. In this paper, a new method has been proposed to take into account both vertical and radial drainage conditions during nonlinear finite strain self-weight consolidation of dredged soil deposits. For 1-D nonlinear finite strain consolidation in the vertical direction, the Morris (2002) theory and the PSDDF analysis are adopted, respectively. On the other hand, to consider the radial drainage, Barron's vertical drain theory (1948) is used. The overall average degree of self-weight consolidation of the dredged soil is estimated using the Carillo formula (1942), in which both vertical and radial drainage are assembled together. A series of large-scale self-weight consolidation experiments being equipped with a vertical drain have been carried out to verify the analysis method proposed in this paper. The results of the new analysis method were generally in agreement with those of the experiments.

  • This study examined the weight control and food habits in 160 obese children and 191 normal-weight children in 4th, 5th and 6th graders of some elementary schools in Gumi city. Regarding the subjects' self-recognition of their body shape, 27.8% of the normal weight group and 92.5% of the obese group acknowledged themselves to be obese. 58.9% of the normal weight group and 61.0% of the obese group were not satisfied with their own body shape and the difference between two groups was very small, 23.6% of the normal weight group and 87.5% of the obese group have tried to reduce weight. The main causative factor of weight gain that children themselves recognized was a sedentary life style. All the students showed a high rate of irregular and unbalanced diet. The obese children showed a significantly higher rate of skipping meals and eating meals faster than the normal weight children. More obese children disliked exercise, and did less excercise than the normal weight children. There was a negative correlation between the obesity index and the food habit score. In other words, they frequently skip a meals, eat in a hurry and dislike vegetables and dairy products. In addition, there was a positive correlation between the student's BMI and the parents' BMI. Overall, many normal weight children showed a high level of self-consciousness of being obese or underweight. Both groups showed a low degree of satisfaction with their own body shape. Therefore education for the distorted perception of body shape is needed because, even normal weight children have tried to reduce their weight. Obese children should be encouraged to exercise, not skip a meals and eat slowly. They also need a systematic education program on weight reduction and weight maintenance. Moreover, education on a healthy diet, healthy food habits, and healthy body shape are necessary for elementary school children.

  • This Quantitative study was investigated to examine the relationship between self-esteem on body image and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely have an eating disorder, including anorexia nervosa and bulimia nervosa. Ideal body weight and current body weight were completed with self-evaluation. A distorted body image was independently related to the eating problem in the Logistic regression analysis. There were stronger relationships between their EAT-26 scores and their expected weight changes and weight control behaviors. Compared with the men, women showed highly wishful to loss for current body weight. In the relationship between score of EAT-26 and BMI distance by sex, levels of eating disorder showed linearly elevated toward increased BMI distance (Ideal BMI-Current BMI) (F-value=18.794, p<0.0001) in women, but there were not significant in men (F-value=2.028, p>0.05). In estimate on state-trait anxiety inventory according to quartile of BMI distance by sex, levels of state-trait anxiety were not significant difference by degree of body dissatisfaction in all sex. In addition, higher distorted body image was significantly increased numbers of weight control method and experience of side effects in female, but there were not showed significant relation between two variables in male.
