The purpose of this study is to describe Eating Behavior for High school boys who are obesity using three factors(dietary restraint, disinhibition, hunger). The subjects were 200 high school boys. The convenience sample is consist of 101 normal weight boys and 99 obeses weight boys. Data were collected between Mat 1 and June 20 in 2000 and analyzed using the SAS package. The results are as follows: 1. The first hypothesis was not supported that is, the normal weight boys much more doing dietary restraint than the obese boys. 2. The second hypothesis was supported that is, the obese boys more experience disinhibition than the normal weight boys. 3. The third hypothesis was supported that is, the obese boys more experience hunger than the normal weight boys. The eating behavior of obese boys is different that of normal weight boys, The obese boys more experience disinhibition and hunger than the normal weight boys, but dietary restraint was more done the normal weight boys than the obese boys.

In this study, we investigate the effects of the weight function in the bounded influence regression quantile (BIRQ) estimator for the AR(l) model with additive outliers. In order to down-weight the outliers of X -axis, the Mallows' (1973) weight function has been commonly used in the BIRQ estimator. However, in our Monte Carlo study, the BIRQ estimator using the Tukey's bisquare weight function shows less MSE and bias than that of using the Mallows' weight function or Huber's weight function. Thus, the use of the Tukey's weight function is recommended in the BIRQ estimator for our model.

Accurate weight prediction methods are an essential of the ship design in both ship cost managements and performance satisfactions. When no parent or similar ships are available, an adequate method of the ship weight estimating is required. In this study, there was carried out to develop the ship weight estimating method for the preliminary design phase. The weight estimating methods were first surveyed by the references and summarized their characteristics. The weight estimation method by statistical approach was developed for the container ship because the containerized transportation markets is gradually growing and ship's size and loading capacity are rapidly enlarged. The correlation analysis and the multiple regression analysis were used for developing the weight estimating method. As a results of evaluating the developed method, the error ratio of the variation between estimated weight and ship's data was about 5%. And it was only 1% difference with the calculating weight of conceptual design results by shipyard design team that the estimating weight of ultra-large container ship was predicted by the developed method.

Purpose: This study aimed to evaluate weight changes in women during the period of TAC (docetaxel-doxorubicin-cyclophosphamide) chemotherapy after breast surgery and the differences in weight changes by disease characteristics among Korean women with breast cancer. Methods: The design of this study was retrospective survey research. The subjects of this study were 130 patients with fully completed TAC chemotherapy between January 2012 and April 2015. Body weight before their operation, and at 3 weeks, 6 weeks, 9 weeks, 12 weeks, 15 weeks, and 18 weeks after surgery, as well as general and disease characteristics, were reviewed via their medical charts. Results: The mean age of the patients was 51.2 years. The preoperative (baseline) mean weight was $59.4{\pm}8.44$. Significant weight losses were observed in the initial (1st 3 week) period of TAC chemotherapy compared to the baseline and significant weight losses were observed with the exception of the period 6 weeks after breast surgery. There were significant differences in mean weight changes according to the stage of breast cancer, radiotherapy, and hormone therapy among disease characteristics. Conclusion: It is necessary to study weight changes after breast surgery for the long periods of TAC chemotherapy. Through the accumulated results of studies, nursing programs for breast cancer patients must be developed for the prevention of weight gain in the periods of TAC chemotherapy.

The purpose of this study was to set up an effective marketing strategy targeting college women by researching the relationship between weight control behavior and body exposure in clothing behavior. The results showed that 1) 85.5% of the college women participated in weight control behavior, and 53.5% of them wanted to lose more than 3kg of their weight. 2) College women were less satisfied with their body and thar showed less body exposure in clothing behavior according to the increase of weight control degree. The weight control parts and unsatisfied body parts were almost matched : thigh, abdomen, hip, calf, and weight. College women preferred clothing that exposed neck, legs and shoulder more than clothing that exposed many parts of their body at the same time. 3) exposure in clothing decreased according to the increase of weight control degree, except for the exposure of breast in clothing.

Adequate nutrient intake during pregnancy is important to fetal and maternal health. The purpose of this study was to investigate the factors affecting birth weight and gestational age and to provide basic data to promote more favorable pregnancy outcomes. Data were collected from 234 pregnant women at two hospitals in Seoul. Demographic characteristics, anthropometric measurements and health related habits were obtained using a questionnaire at the hospital visit during the second trimester. Dietary intakes were estimated by 24 hour recall at the hospital visit during the second trimester. Data on pregnancy outcomes, including birth weights and gestational ages, were obtained from hospital records after delivery. Birth weights were divided into a low birth weight group (birth weight<3.1 kg), a normal birth weight group (3.1-3.6 kg) and a high birth weight group (>3.6 kg). Gestational ages were divided into tertiles according to the gestational age of the subjects: group 1 (<38.53 weeks), group 2 (38.53-40.00 weeks) and group 3 (>40.00 weeks). The number of family members was significantly lower in the low birth weight group than in the normal birth weight group (p<0.05). In the low birth weight group, pregnancy weight was significantly lower than in the high birth weight group (p<0.05) Health related habits were not significantly different among any of the groups. Intakes of fiber, phosphorous, iron, vitamin $B_6$ and folic acid were significantly higher in the high birth weight group than the low birth weight group (p<0.05). Gestational age was not significantly affected by nutrient intakes, but birth weight was affected by nutrient intake in the results of this study. Therefore, the adequacy of nutrient intake is important for the improvement of pregnancy outcomes.

In this study, the interest of female high school students's(N=500) for weight control, as well as nutrient intake status, were analyzed. The mean age, height, and weight of the subjects were, 19.3 years, 162.2 cm and 55.4 kg respectively. Mean BMI was $21.1 kg/m^2$. According to BMI, the percentage of underweight, normal weight, overweight, and obese were 18.5 %, 60.3%, 11.3%, and 11.3% respectively. By the BMI criteria, 60.3% of the subjects were normal weight while the rate of self-recognition was 41.5%. The degree of satisfaction regarding self-body image was only 17.1% and 60.9% showed an interest in weight control. The reason for weight reduction were appearance(65.1 %) and health(24.2%). The body areas where subjects wanted to lose weight included the thighs(32.9%) and whole body(29.3%). They believed the most effective weight control strategy was exercise(81.1 %) and the strategies they used were diet(59.1 %) and exercise(40.4%). Energy intake was 1,733.4 kcal which was 86.7% of the estimated energy requirements(EER). Calcium, vitamin $B_2$, and vitamin C intakes were less than EAR by 34.4%, 40.4%, and 59.6% respectively. The intake of dietary fiber was 5.1 g only 21.1 % of the adequate intake(AI). In summary, high school females interested in weight control have significantly less calcium intake than their peers. The correlations between interest in weight control and weight and BMI were significant(p<0.001). The results of this study suggest that to achieve optimal growth, improved diets that include calcium, vitamin $B_2$, and vitamin C are recommended. High school females interested in weight control should especially be targeted for education on calcium intake.

Obesity is a chronic disease that is increasing in prevalence and that poses a serious risk for the hypertension, osteoporosis, heart disease, diabetes mellitus and certains forms of cancer. This study was performed to develop of obesity animal model and to assess the pharmacological assay for the rats of 8 weeks or 4 days after ovariectomization treated with estradiol for 8 weeks on the body weight. fat weight and food intake. The body weight, fat weight and food intake increased in the ovriectomized rats. In the rat of 8 weeks after ovariectomization treated with estradiol (250 mg/100 g) 8 weeks, the body weight decreased significantly (p<0.05). In the rats of 4 days after ovariectomization treated with estradiol 8 weeks, the body weight decreased significantly (p<0.05). These results suggest that estrogen plays a role in regulation body weight response to food intake and fat weight.
