Background: Previous epidemiologic studies on the association between energy intake and endometrial cancer risk have only generated contradictory results. The role of energy intake in endometrial carcinogenesis thus remains unclear. To quantitatively assess the potential association between energy intake and endometrial cancer, a meta-analysis of case-control and cohort studies was here conducted. Materials and Methods: Eligible studies were retrieved via both computerized searches and review of references. Fixed-or random-effect models were used to summarize the estimates of OR with 95%CIs. Stratified analyses on study design, region and macronutrients' calorie were performed. Results: Sixteen studies met the inclusion criteria of the meta-analysis. No association between total energy intake and endometrial cancer was observed in either overall group (OR=1.11, 95%CI 0.92-1.30) or subgroups stratified by study design and region. In the specific macronutrients' calorie analysis, higher fat energy intake was found to be associated with increased endometrial risk (OR=1.72, 95%CI 1.12-2.32) while energy from carbohydrate and protein was not related to endometrial cancer risk. Conclusions: Our analysis did not support that total energy intake is related to endometrial cancer risk, in contrast to fat energy.

The purpose of this study is to collect basic data which are prerequisite for quantitative analysis of coal logging data. The study involves laboratory measurements of physical properties such as seismic velocities (P,S-waves), resitivity and density of domestic and imported foreign coals. The relationships between these properties were analyzed by using cross-plots. Correlation between the physical properties of coal and the results of chemical analysis (calorie, fixed carbon, ash, moisture, volatile matter and sulfur contents) was also studied to obtain ideas about coal quality analysis using logging data. Summarized results are as follows: 1. $V_P$ is exponentialy related to $V_S$. And the average value of $V_P$ is about l.8 times as large as $V_S$. 2. Since coal has very low density compared with surrounding sedimentary rocks, density logging is appeared to be the best method for identifying coal seams and evaluating their qualities. 3. For the case of domestic coals, the ash contents and calorie show a perfect inverse relationship. Since the density increases as increase of ash content with a well-defined functional form, the ash content of domestic coals can be estimated by density measurements. 4. Because of low ash content, low density and high resistivity, foreign coals and domestic lignites are easily distinguished from domestic coals.

Objectives: The purpose of this study was to identify the differences in nutrient intake according to using diuretics, symptom severity and degree of physical functioning in heart failure patients. Methods: A secondary data analysis was conducted by using baseline data of an intervention study for heart failure patients. In this study, 131 heart failure patients were included. Data were collected using medical records, NYHA (New York Heart Association functional classification) class, and 6-minute-walking test and 24-hour diet recall. Data were analyzed using descriptive statistics and Chi-square test by SPSS 21.0. Nutrient intake was assessed using CAN-pro 2.0. Results: Majority of the participants consumed total calorie less than Estimated Energy Requirement (EER) and consumed carbohydrates more than 65% of their total calorie intakes. 24.4% of the participants consumed fat more than 30% of their total calorie intakes and 23.7% consumed saturated fat more than 7% of their total calorie intakes. 100.0% of the participants consumed protein less than 7% of their total calorie intakes and 73.3% of the participants consumed more than recommended intakes of sodium. More than 90.0% of the participants consumed less than adequate intakes of potassium (90.1%) and Vitamin D (91.6%), respectively. 100% and 62.6% of the participants consumed less than Estimated Average Requirement (EAR) of magnesium and Vitamin $B_1$, respectively. Nutrient intakes in heart failure patients were different for potassium intake according to the usage of diuretics. The participants with symptom severity tended to intake protein less properly and the participants walking more than 300.0 m tended to intake sodium improperly high. Conclusions: The findings of this study indicated the need for screening nutrient intakes of heart failure patients. It is necessary to increase the intake of total calories and most nutrients and to restrict sodium intakes among heart failure patients.

This study was designed to investigate the effect of nutrient intake on bone mineral density (BMD) of the lumbar spine(L2longrightarrowL4) in 41 postmenopausal women. The BMD of the lumbar spine was positively correlated with caiorie protein animal protein fat animal fat calcium animal calcium milk ad dairy calcium phosphorus iron animal iron vitamin A thiamin animal calcium milk and dairy calcium phosphorus iron animal iron vitamin A thiamin riboflavin niacin and ascorbic acid intake. Postmenopausal wmen of BMD$\geq$100% showed enhanced calorie protein fat calcium phosphrous niacin intake compared women of BMD<100% In the group of calorie protein riboflavin intake$\geq$recommended dietary allowances(RDA) BMD was significantly higher than BMD in the group of these nutrient intakes$\geq$700 mg/d is significantly higher than BMD that of examined using stepwise multiple regression analysis. From this analysis in subjects aged 50~59 years fat intake only in subjects aged 60~69 years niacin intake Ca/P in total subjects fat riboflavin intake were signifiant independent predictors of BMD In the group of menopausal significant independent predictor of BMD This study suggests that dietary calcium is a major constituent affecting lumbar spin BMD in postmenopausal women whose menopausal period is over than 5 years.

The rats with protein-calorie malnutrition (PCM, 5％ casein diet for a period of 4-week) were reported to exhibit 60 and 80％ suppression in the hepatic microsomal cytochrome P450 (CYP) 1 A2 and CYP2C11 levels, respectively, and 40-50％ decreases in CYP2E1 and CYP3A 1/2 levels compared to control (23％ casein diet for a period of 4-week) based on Western blot analysis. In addition, Northern blot analysis showed that CYP1 A2, CYP2E1, CYP2C11, and CYP3A1/2 mRNAs decreased in the state of PCM as well. Hence, pharmacokinetic changes of the drugs in rats with PCM [especially the area under the plasma concentration-time curve from time zero to time infinity (AUC) changes of metabolite(s)] reported from literatures were tried to explain in terms of CYP isozyme changes in the rats. Otherwise, the time-averaged nonrenal clearance ($CL_{NR}$) of parent drug was compared. Pharmacokinetic changes of the drugs in other types of malnutritional state, such as kwashiorkor and marasmus, in both human and animal models were also compared. The drugs reviewed are as follows： diuretics, antibiotics, anticancer agents, antiepileptics, antiarrythmics, analgesics, xanthines, antimalarials, and miscellaneous.

This study investigates differences in middle school male students' anthropometric variables and dietary habits using BMI (Body Mass Index) classifications. $\chi^2$ -test for frequency and ANOVA test for mean value and duncan value were used to analyze results. Averaged results of three groups of middle school male students' anthropometry including height (normal group 164.4 cm, overweight group 165.0 cm, obese group 167.0 cm), weight (normal group 56.0 kg, overweight group 70.0 kg, obese group 83.2 kg) and waist circumference (normal group 20.7 cm, overweight group 79.8 cm, overweight group 89.6 cm) were resulted. Classification of obese group was based upon 2007 growth charts using BMI criteria. This study indicates the normal weight group boys have over-eating related dietary habits and the obese groups have less calorie dietary habits. They answered oppositely to normal recognition. The obese group reflected dietary problems, such as preferences for sweet fruit rather than normal group males. Dinnertime of the groups were significantly different and obese group's earlier dinnertime can influence on their late night snack eating. Forty precent of obese male group like fruits as late night eating food. Three meal amount of three groups were significantly different, as obese group answered they ate same amount at every meal. It can mean obese group ate more amount of food in every meal. Overweight and obese male students have dietary problem of fast eating and answers of unbalanced eating were higher in normal group. These could mean obese group eats well in every food and fast eating habit could lead a lot of food eating habit. Obese group chooses out-going food of less calorie and frequency of fast food eating was lower than normal group. In result, obese group answered that they have less calorie related dietary habits, it could mean their answers were false or fixed dietary habit. Therefore, more researches should be followed.

The present study assessed the relation of dietary fiber to food habits in Korean adults aged 20 and over, using a newly established dietary fiber, as well as the 2001 Korean National Health and Nutrition Survey. The per capita average dietary fiber intake of Koreans was estimated to be 12.25 ${\pm}$ 5.23 g/1,000 kcal. Calorie-based dietary fiber intakes for females was over the KDRl, but for males it was below the KDRI. The levels of total dietary fiber and energy corresponded with frequent snacking but calorie-based dietary fiber intake did not. The subjects who skipped meals, frequently ate out and consumed fried foods tended to have lower levels of calorie-based dietary fiber although the levels of energy and total dietary fiber corresponded with frequent eating-out and consumption of fried foods. The results of this study suggest that Koreans must make efforts to regularly have three meals a day, reduce the frequency of eating out and consume fewer fried foods in order to maintain the optimum intake levels of dietary fiber that protect against chronic diseases.

This study surveys the state of 'children's snacks' sold within the Green Food Zone and that of High Calorie Foods with Low Nutrition Value (HCFLNV). The main purposes are the analyses of foods in accordance to KFDA Program for HCFLNV and an analysis of differences in HCFLNV that are dependent on relevant factors such as food types, school types, origins, the scale of manufacturing company, area and price. Based on the analyses, educational and political implications have been sought that will form nutritious dietary habits, contribute to the prevention of obesity, and improve health in child consumers. The methodologies of this study are literature studies and surveys. The results of this study can be summarized as following. First, the number of children's snacks is 517 items of total 645 gathered within 150 Green Food Zones. Candies are the most popular item, next are cookies, chocolates, and breads. Second, in the real state survey there are 186 HCFLNV (36.0%) among children's snacks sold within Green Food Zone. Based on the survey results, the marking of HCFLNV on the package of children's snacks and the extension of the ban of HCFLNV sales to all stores within the Green Food Zone are strongly suggested. This provides preliminary data related to children's snacks and food safety. With enforcement of the Special Act on the Safety Management of Children's Dietary Life, the rate of HCFLNV has decreased and the child snack product environment in stores has improved. However, it is necessary to supervise low-priced snacks and promote an awareness of HCFLNV along with the child consumer education of food safety is needed.
