In order to study the relationship between body core temperature and adiposity , the core temperatures of normal weight female college students were measured during an instant-noodle lunch eaten in a laboratory at the ambient temperature of 22-24.8$^{\circ}C$. Ambient temperature was positively correlated with meal-start core temperature and meal duration. The difference between the peak postprandial and the meal-start core temperature was negatively correlated with body weight and BMI. This means that the thermogenic response induced by meal consumption was negatively associated with adiposity. Meal duration also showed a negative correlation with body weight, BMI, and hip girth. Thus, the obese eating style characterized by a rapid rate of food intake was also associated with adiposity in normal weight women. It was possibly a contributing factor in the development of obesity. In conclusion, adiposity is negatively associated with the difference between the peak postprandial and the meal-start core temperature and meal duration during a meal.
With the aim of diagnostic research on health education. the health promoting behaviors related to elementary school students' weight control. life satisfaction. health state. self-efficacy. parent's interest and knowledge about weight control and school health education of weight control were investigated on the basis of the PRECEDE model. The data for this study were collected from a sample at an elementary school in Chongju for 5 days in July. 2004. In analyzing the data. t-test. one-way ANOVA. chi-square test and multiple regression analysis were done by using SPSS 10.1 The results were as follows : 1. The elementary school students' level of life satisfaction was above half of the full point. The score difference of life satisfaction was statistically significant by grade and academic achievement(F=4.646. p=.010. F=16.042. p=.000). 2. The perceived level of health state was moderate for all students. Normal weight students' level was significantly higher than obese students' (t=3.667. p=.000). 3. The perceived level of health promoting behaviors related to weight control was above the moderate. The perceived level of health promoting behaviors related to weight control in the obese students was significantly higher than that in normal weight students(t=-2.225. p=.027). The students used computer for 1.48 hours and watched TV for 2.52 hours a day. 4. The score of health promoting behavior self-efficacy in this subject was 70.61. 5. The parents' level of interest in the obese students' weight control was significantly higher than that in the normal weight students(t=-4.86. p=.000). 6. Sixty-six percent of the students learned about weight control education in school. 7. The health promoting behavior self-efficacy among the educational diagnostic variables was the most influential variable in students' health promoting behaviors related to weight control. This research diagnosed the needs of weight control education in elementary school by assessing various factors related to weight control behaviors. The research findings suggest that we can enhance the prevention of childhood obesity by strengthening the related factors such as parents' knowledge and interest, health promoting behaviors and self-efficacy related to weight control in school health education.

As for the dead-weight, the pneumatic, and the hydraulic method, the load control performance against external disturbances was estimated under the several loading conditions like the different sliding speed, the varied normal load, and the misaligument. The hydraulic loading method showed the most stable loading performance of all the loading methods in the experiment.
Purpose: This study aims to provide preliminary data for weight management, and prevention and management of cardiovascular and cerebrovascular diseases. We examined the effect of changes in the weight of workers at a manufacturing company over three years on their metabolic syndrome and metabolic syndrome diagnosis components. Methods: Necessary data were collected from the questionnaire and the results of the Korean National Health Screening of 2015 and 2017, which included 228 workers at a manufacturing company in G region. The collected data were analyzed using the SPSS/WIN 23.0 program. ANCOVA was used to examine the differences in the metabolic syndrome diagnosis components according to weight change. In addition, multiple logistic regression analysis was used to obtain the odds ratios of metabolic syndrome and metabolic syndrome analysis component, based on the weight changes in the normal weight group and the obesity group. Results: Waist measure, systolic blood pressure, and blood pressure were found to have significant effects based on participants' weight change over three years. These factors increased with a larger increase in weight at a statistically significant level. This study analyzed the weight changes of the normal weight group and the obesity group considering the data from the National Health Screening of 2015, and found that the risk of metabolic syndrome increased at a statistically significant level as body weight increased; thus, the obesity group showed a higher risk in this regard. It was also found that waist measure, fasting blood sugar, and high-density low cholesterol increased at a statistically significant level as body weight increased. Conclusion: Health administrators need to recognize the importance of workers' weight management, select an intensive management group based on a time series analysis of weight changes, and develop and implement programs to manage the metabolic syndrome diagnosis components.

This study was conducted to identify the BMI of enlisted soldiers, to understand the difference between their BMI and that of other men in their age group, and to identify the influence factors of enlisted soldiers' BMI change. The survey has been conducted self-evaluation questionnaire from 23 Feb. 2009 to 31 Mar. 2009 from 4 different forces as methods. Independent-sample T-test, chi-square test and multiple linear regression analysis were used for statistical analysis from 301 collected data. As a result of surveying enlisted soldiers' BMI, their obesity rate 18.6% was lower than 22.1% of other men in their age group. In terms of health behavior, the underweight&normal weight group(2.39) showed higher diet score than the overweight group(2.13), showing that the underweight&normal weight group ate relatively slowly, less spicy and less sweet food compared to the overweight group. The overweight group(2.25) showed lower satisfaction with their body type than the underweight&normal weight group(2.98), while the overweight group(4.01) showed a significantly higher score than the underweight&normal weight group(3.37) for weight control activity. The influence factors of BMI change were diet habit, subjective perception of body type, and weight control activity. In order to improve of enlisted soldiers' BMI, it would be necessary to improve the food service and the snack bars for interventional control of food that influence obesity, rather than personal effort, in addition, education for right body-shape perception and encouraging on weight control activity.
Objective : This study was purposed to investigate the acute. subacute toxicity of Herbal acupuncture with Juglandis Semen(JsD) in mice and rats. Methods & Results: Balb/c mice were injected intraperitoneally with JsD for $LD_{50}$ and acute toxicity test Sprague-Dawley rats were injected intraperitoneally with JsD for subacute toxicity test.

In subacute toxicity test, treat groups were not changed serum biochemical values of rats, compared with normal group.(P<0.05) Conclusions: According to the results, Herbal-acupuncture with Juglandis Semen caused no toxicity.
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.
This study was conducted to investigate whether dietary factors, normal fat and genistein leads to beneficial improvement of lipid metabolism and oxidative stress in adult hyperlipidemic male rats. Seven wk-old male SD rats were fed high fat diet (15% fat, 1% cholesterol) for 4 wks for induction of hyperlipidemic model rat. Weight-matched rats were then assigned to four groups according to dietary fat level (7% or 15% fat) and genistein contents (0 or 320 mg/kg diet). Food intake was significantly decreased by both high fat intake and genistein supplementation compared with normal fat intake and genistein no supplementaion. But weight gain was significantly decreased by genistein supplementation in normal fat intake compared with the other groups. Total lipid, total cholesterol and triglyceride in serum and liver were significantly decreased by normal fat intake compared with high fat intake. But total cholesterol in liver was significantly increased by genistein supplementation in both high fat and normal fat intake. TBARS in serum and liver was less produced by normal fat intake compared with high fat intake but TBARS in liver was significantly increased by genistein supplementation compared with genistein no supplementation in normal fat intake. Glutathione reductase activity in erythrocytes was significantly reduced by genistein supplementation in normal fat intake compared with the other groups. Glutathione peroxidase and glutathione reductase activities in liver were significantly inhibited by normal fat intake compared with high fat intake. Catalase activity in liver was significantly increased by genistein supplementation compared with genistein no supplementation in high fat intake. Nitrite was significantly decreased by normal fat intake compared with high fat intake. These results suggest that normal fat intake has the treatment effect against risk factors related with cardiovascular disease by reducing lipid profiles, lipid peroxidation. And genistein shows action as a antioxidant replacing antioxidant enzymes but also may act as prooxidant causing the production of TBARS.

This study was conducted to identify factors influencing weight loss efforts in hypertensive patients with obesity in Korea using data from the 2016-2019 National Health and Nutrition Examination Survey. Weight perception, weight loss efforts, and weight control methods were investigated for 1,910 subjects. Data were analyzed using descriptive analysis, cross-tabulation analysis and logistic regression. Among obese hypertensive patients, 12.6% perceived their weight as normal. Weight loss efforts were 2.03 times (95% CI: 1.48 to 2.78) higher in people with overweight perception than those with normal weight perception, and 1.74 times (95% CI: 1.33 to 2.26) higher in women than in men. In addition, those with class 1 obesity were 1.50 times (95% CI: 0.85 to 2.65) higher than those with class 3 obesity, and those with class 2 obesity were 2.16 times (95% CI: 1.16 to 4.00) higher than those with class 3 obesity. These results suggest that weight management approaches for hypertensive patients with obesity should be individually designed according to weight perception, gender, and obesity class.
