  • Weight change in the postpartum period is a dominant concern of new mothers recently. Postpartum weight retention has important public health implications as well, because retention of gestational weight can be a significant contributor to longterm obesity and associated health risks. As traditional medical practitioners have managed some problems from postpartum weight retention, use some terms translated in Korean like as postpartumedema, obesity. But those have been not given any discuss objective and with evidences for nomenclature. Now reports review normal postpartum weight loss patterns, as well as risk factors for weight retention, ancient literatures, so practitioners can assist their patients in achieving a healthy postpartum weight.

  • 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.

  • The basic structure for assessment of potential health risks from environmental chemicals is widely agreed upon, but many of the details of risk assessment procedures differ among practitioners. Government regulatory agencies typically have guidelines or standard procedures for their risk assessments, established to ensure consistency and comparability, to set standards for adequacy, and to embody underlying tenets. In setting and updating such guidelines, each agency takes into account not only the prevailing thinking about appropriate procedures, but also its own goals and responsibilities and the precedents it has set for itself in past analyses. This results in variations in methods, and consequently in characterization of risks, among regulatory assessments, even when they are based on the same data. As a result, adopting existing assessments from a variety of regulatory bodies needs to be done with caution. This paper examines some of the variants in risk assessment approaches among American federal regulatory agencies and relates them to the variations in regulatory responsibilities of those groups. Comparisons to international practices are also drawn. The impact on development of world-wide risk standards is discussed.

  • Present time there are many risk analysis method in the world. A hazard is an exposure that has the potential to induce and adverse event. Risk is the probability of an adverse event given exposure to hazard. The evaluation of scientific information on the hazardous properties of environmental agents and the extent of exposure to these agents. But operation risk analysis method is not enough for manufacturing industry even if it is existence, it will be separated to improve Safety. In this paper, I will develop the AHP Weighted operation risk analysis method to improve Safety.

  • Objective: Enterotypes (ETs) are the clustering of gut microbial community structures, which could serve as indicators of growth performance and carcass traits. However, ETs have been sparsely investigated in waterfowl. The objective of this study was to identify the ileal ETs and explore the correlation of the ETs with growth performance and carcass traits in Muscovy ducks. Methods: A total of 200 Muscovy ducks were randomly selected from a population of 5,000 ducks at 70-day old, weighed and slaughtered. The growth performance and carcass traits, including body weight, dressed weight and evidenced weight, dressed percentage, percentage of apparent yield, breast muscle weight, leg muscle weight, percentage of leg muscle and percentage of breast muscle, were determined. The contents of ileum were collected for the isolation of DNA and 16S rRNA gene sequencing. The ETs were identified based on the 16S rRNA gene sequencing data and the correlation of the ETs with growth performance and carcass traits was performed by Spearman correlation analysis. Results: Three ETs (ET1, ET2, and ET3) were observed in the ileal microbiota of Muscovy ducks with significant differences in number of features and α-diversity among these ETs (p<0.05). Streptococcus, Candida Arthritis, and Bacteroidetes were the presentative genus in ET1 to ET3, respectively. Correlation analysis revealed that Lactococcus and Bradyrhizobium were significantly correlated with percentage of eviscerated yield and leg muscle weight (p<0.05) while ETs were found to have a close association with percentage of eviscerated yield, leg muscle weight, and percentage of leg muscle in Muscovy ducks. However, the growth performance of ducks with different ETs did not show significant difference (p>0.05). Lactococcus were found to be significantly correlated with leg muscle weight, dressed weight, and percentage of eviscerated yield. Conclusion: Our findings revealed a substantial variation in carcass traits associated with ETs in Muscovy ducks. It is implied that ETs might have the potential to serve as a valuable biomarker for assessing duck carcass traits. It would provide novel insights into the interaction of gut microbiota with growth performance and carcass traits of ducks.

  • The purpose of this study was to investigate the age-related changes of cardiovascular disease risk factors and inflammatory markers in non-obese Korean women. Subjects were 112 women over 20 years old with body mass index (BMI) less than $30 kg/m^2$ and were divided into 3 groups (< 40 years, $40{\sim}59$ years, ${\ge}60$ years). Mean weight and BMI in the oldest group were significantly higher than those in the other 2 younger groups (p < 0.05). Mean total cholesterol, triglyceride, LDL-cholesterol and apolipoprotein B/apolipoprotein A1 ratio (BAR) in the oldest group were significantly higher than those in the youngest group (p < 0.05), and mean HDL-cholesterol of the oldest group was significantly lower than that of the youngest group (p < 0.05). The older-aged group showed significantly higher mean values of atherogenic index (AI) and LDL/HDL ratio (p < 0.05) than the respective younger-aged group, and AI was significantly correlated with age, nitric oxide and thiobarbituric acid reactive substances (p < 0.01). In addition, mean vascular cell adhesion molecule-l (VCAM-1) tended to be higher in the older-aged group than the younger group. Tumor necrosis factor-${\alpha}$, a proinflammatory maker, was significantly positively correlated with serum homocysteine, a cardiovascular disease risk factor (p < 0.01). In addition, a significantly positive correlation was observed between C-reactive protein and BAR (p < 0.01). Overall results suggested that the aging might affect the increase of cardiovascular disease risk factors including the serum lipid profiles, weight and BMI, and age-related increases of weight and BMI might play a role in changes in certain biomarkers of inflammation.

  • Diet attrition and failure of long term treatment are very frequent in obese patients. This study aimed to identify pre-treatment variables determining dropout and to customise the characteristics of those most likely to abandon the program before treatment, thus making it possible to modify the therapy to increase compliance. A total of 146 outpatients were consecutively enrolled; 73 patients followed a prescriptive diet while 73 followed a novel brief group Cognitive Behavioural Treatment (CBT) in addition to prescriptive diet. The two interventions lasted for six months. Anthropometric, demographic, psychological parameters and feeding behaviour were assessed, the last two with the Italian instrument VCAO Ansisa; than, a semi-structured interview was performed on motivation to lose weight. To identify the baseline dropout risk factors among these parameters, univariate and multivariate logistic models were used. Comparison of the results in the two different treatments showed a higher attrition rate in CBT group, despite no statistically significant difference between the two treatment arms (P = 0.127). Dropout patients did not differ significantly from those who did not dropout with regards to sex, age, Body Mass Index (BMI), history of cycling, education, work and marriage. Regardless of weight loss, the most important factor that determines the dropout appears to be a high level of stress revealed by General Health Questionnaire-28 items (GHQ-28) score within VCAO test. The identification of hindering factors during the assessment is fundamental to reduce the dropout risk. For subjects at risk, it would be useful to dedicate a stress management program before beginning a dietary restriction.

  • The purpose of this study was to investigate body cathexis and clothing involvement by demographic characteristics and to indentify the relationship between body cathexis and clothing involvment. Five aspects of body cathexis(lower body, head/upper body, height, weight, torso) were assessed with 17 Likert type questionnaires adapted from the previous researches, and 24 items of clothing involvement were measured. The questionnaire was administered to 430 women in Taegu, Korea. The data were analyzed using percentage, frequency, factor analysis, ANOVA, Sceffe test, t-test, and Pearson's Correlation Analysis. The results of the study were as follows; 1. The body cathexis showed head/upper body, height, torso, lower body, weight in order of satisfaction level. Especially lower body and weight part were shown as the most unsatisfactory body parts. Age of 20s' showed the lowest body cathexis, and those who had the higher educational background and family income were more satisfied with their bodies. 2. Five dimensions of clothing involvement were derived by factor analysis such as fashion, interest, pleasure, symbolism, and perceived buying risk. 3. There were significant relationships between clothing involvement dimensions and demographic characteristics such as age, educational background and family income level. Those who were younger showed positive relationship partially among fashion, interest and pleasure of clothing dimensions but showed negative relationship in total clothing involvement. Those who had higher educational background and family income showed positive clothing involvement than married women and empolyed showed higher clothing involvement with symbolism and perceived buying risk than unemployed women partially but not in total clothing involvement with symbolism and perceived buying risk than unemployed women partially but not in total clothing involvement. 4. There were significant relationships between body cathexis and interest, perceived buying risk of clothing involvement partially. However, the correlation between body cathexis and total clothing involvement was relatively low.

  • A substantial body of evidence has emerged over the last decade in support of the novel concept that dietary calcium and dairy foods play an important role in regulating energy metabolism and thereby promote healthy weight management and reduce obesity risk. This concept has been demonstrated in experimental animals studies, cross-sectional and prospective population studies and a number of randomized clinical trials. Notably, the effects of dairy foods in weight management are more consistent than the effects of supplemental calcium across clinical trials, and calcium per se is responsible for approximately 40-50% of the effects of dairy. The calcium component is only effective in individuals with chronically low calcium intake, as it serves to prevent the endocrine response to low calcium diets which otherwise favors adipocyte energy storage; calcium also serves to promote energy loss via formation of calcium soaps in the gastrointestinal tract and thereby reduce fat absorption. The calcium-independent anti-obesity bioactivity of dairy resides primarily in whey. The key components identified to date are leucine and bioactive peptides resulting from whey protein digestion. The high concentration of leucine in whey stimulates a repartitioning of dietary energy from adipose tissue to skeletal muscle where it provides the energy required for leucine-stimulated protein synthesis, resulting in increased loss of adipose tissue and preservation of skeletal muscle mass during weight loss. Finally, dairy rich diets suppress the oxidative and inflammatory responses to obesity and thereby attenuate the diabetes and cardiovascular disease risk associated with obesity.

  • This study was carried out to provide information on the related factors for child obesity through investigation of children aged 6-12. Data was obtained on family history, dietary habits and physical examinations. Children were classified into normal(98 persons) and obese (108 persons) groups using combinations of the height f3r age, weight fir age, and weight fir height standards used by the World Health Organization. Children's height, weight and BMI showed significant differences between groups except children aged 8 for height. Birth weight, breast feeding and unbalanced diet were not associated with obesity. Overeating was a risk factor in the obese group(Odd ratio : 3.417, 95% CI 1.879-6.212). Taking nutrition pills was correlated to obesity. Odd ratio for taking nutrition pills was 0.109(95% CI : 0.024-0.492) between normal and obese group. Number of brothers didn't have any correlation to obesity. Obesity was not correlated to mother's education level or employmental status. As the result of this study, children's obesity was related to overeating and taking nutrition pills. Therefore, these results suggest that systematic dietary education and continuous parental supervision are necessary to avoid child obesity. (Korean J Nutrition 31(7) : 1158-1164, 1998)
