This study aims to provide the basic data for coffee intake and health promotion by examining the conditions in which Korean adults consume the most coffee. The study used raw data from the second year of the 7th National Health and Nutrition Examination Survey (2017), and 3,325 subjects who were 19 years of age or older and who were not missing the required values. This number used as the average amount of coffee drank per day in the past year is at least one cup. In order to identify factors that affect coffee intake, the model included general characteristics such as gender, age, household income, education level, occupation, health behaviors such as smoking, drinking, high intensity and moderate intensity exercises, walking, physical activity during work and leisure, sleep time, stress and depression. The results showed that coffee intake was lower among women than men, coffee intake was higher for people 40-64 years than people 20-39 years old, physical occupations rather than non-physical occupations, smokers rather than non-smokers, and for high stress rather than low stress in life. Subjects with these factors are considered to be at risk of excessive caffeine intake from coffee. The risk group of this study should be studied for the effect of excessive consumption of coffee on personal health.

Obesity contributes to an increased risk for chronic diseases, including diabetes, cardiovascular diseases, and certain types of cancer. The prevalence of obesity has increased in Korea. We compared the clinical and dietary characteristics of obese adults (n = 30, 17 men and 13 women, mean age 29.9) to those with a normal weight (n = 15, 8 men and 7 women, mean age 26.5). We determined lipid profiles, fasting blood sugar (FBS), blood pressure, and serum free fatty acid (FFA). Dietary intake was estimated using a food frequency questionnaire (FFQ) and a 3-day dietary record. Exercise patterns and average alcohol intake were determined. The average body mass index was 28.3 kg/$m^2$ in the obese and 21.2 kg/$m^2$ in the normal weight groups. The obese group had significantly higher levels of total cholesterol, LDL cholesterol, and triglycerides, lower levels of HDL cholesterol, and higher blood pressures compared to the normal weight group. FBS was not significantly different between the two groups. The obese group had significantly more subjects with metabolic syndrome (26.7%) compared to the normal weight group (0%). Serum FFA levels tended to be higher in the obese (P = 0.087). No significant difference in caloric intake was observed between the two groups. No differences in carbohydrate, protein, or fat intake between two groups were observed from the FFQ. However, results from the 3-day dietary record showed that the percentage of energy from fat was significantly higher in the obese group. The frequency and amount of exercise did not differ between the two groups. Alcohol consumed per drinking episode was significantly higher in the obese group. These results confirm that excessive weight is associated with disturbances in lipid metabolism in these fairly young and otherwise healthy adults. Dietary factors, including higher fat intake and alcohol consumption, seem to be contributing to the obesity of these subjects.

Nitrate contamination in water system is a critical environmental problem caused by excessive application of chemical fertilizer and concentration of livestock. In order to prevent further contamination, therefore, it is necessary to understand the origin of nitrate in nitrogen loading sources and manage the very source of contamination. The objective of this study was to examine the nitrate contamination sources in different agricultural system by using nitrogen isotope ratios. Groundwater and runoff water samples were collected on a monthly basis from February 2003 to November 2003 and analyzed for nitrogen isotopes. The nitrate concentrations of groundwater in livestock fanning area were higher than those in conventional and organic fanning area and exceeded the national drinking water standard of 10mg N/ l. The ${\delta}^{15}N$ranges of chemical fertilizer and animal manure were - 3.7${\sim}$+2.3$\textperthousand$ and +12.5${\sim}$26.7$\textperthousand$, respectively. The higher ${\delta}^{15}N$ of animal manure than those of chemical fertilizer reflected isotope fractionation and volatilization of '''N. The different agricultural systems and corresponding average nitrate concentrations and ${\delta}^{15}N$ values were: conventional farming, 5.47mg/e, 8.3$\textperthousand$; organic fanning, 5.88mg/e, 10.1$\textperthousand$; crop-livestock farming, 12.5mg/e, 17.7%0. These data indicated that whether conventional or organic agriculture effected groundwater and runoff water quality. In conclusions, relationship between nitrate concentrations and ${\delta}^{15}N$ value could be used to make a distinction between nitrate derived from chemical fertilizer and from animal manure. Additional investigation is required to monitor long-term impact on water quality in accordance with agricultural systems.

Amount of lead burden in a tissue reflects poisoning of lead in that tissue, so is the removal of lead directly connected to curement of lead poisoning. The purpose of present study was to investigate the relative effects of penicillamine and thiamine tetrahydrofurfuryl disulfide (TTFD) or thiamine propyl disulfide (TPD) in the removal of lead from rat brain tissue treated with excessive lead. Wistar rat pups of both sexes were used in this experiment. Within 1 day of parturition, experimental mothers nursing their pups as well as rat pups were given drinking water containing 0.2% lead acetate, TTFD 20mg/1.2 L (2 mg/kg/day), TPD 20 mg/1.2 L (2mg/kg/day), penicillamine 40 mg/1.2 L (40 mg/kg/day), 0.2% lead acetate+TTFD 20mg/1.2 L (2 mg/kg/day), 0.2% lead acetate+ TPD 20 mg/1.2 L (2 mg/kg/day) or 0.2% lead acetate+ penicillamine 40 mg/1.2 L (40 mg/kg/day) ad libitum, throughout the entire period of experiment. Rat pups in the control group received normal tap water. The animals were sacrificed by decapitation on the day when they become 2 or 8 weeks of age. Brains were dissected into five regions: telencephalon, diencephalon, midbrain, pons/medulla and cerebellum. The dissected brain tissues were lyophillized and then solubilized by acid mixture (nitric acid + sulfuric acid). Lead levels in the solubilized brain tissues were measured by the inductively coupled plasma. In lead-exposed rats, lead levels were significantly higher than those of control group in all brain legions, lead levels in brain regions of TTFD or TPD group were generally lower than those of control group. The simultaneous administration of lead with TTFD or TPD to animals caused significant decrement of lead from all brain regions. In the elimination of lead from brain regions, effectiveness of TTFD or TPD was equivalant to penicillamine.

This study was conducted to evaluate the rate of obesity of 212 women (age 45-60 years) in Seoul and the Kyunggi area through analysis of BMI and the dietary life factors related to obesity using a survey on dietary habits, dietary assessment, and nutrient intake. The height of the underweight group was taller than normal. The height of the obese group was equal to that of the normal group, but the weight was 8.5 kg greater than the normal group. Women in the underweight group consumed meals irregularly, and only 33.4% ate breakfast. Additionally, the rate of overeating was low in the underweight group, and milk, dairy products (yogurt, etc.), fruit, and fruit juice were consumed more than once a day. It was found that 62.1% of the women in the obese group never ate out, and the rate of eating one serving of fruit, drinking one cup of fruit juice, and eating various kinds of foods was high. The average point of women's dietary life was $21.9{\pm}2.9$, and 12.7% of all women responded that their dietary life was good. However, in the obese group, only 6.9% of the women reported that their dietary life was good. Evaluation of snacking habits revealed that the underweight group consumed a high level of carbonated drinks and ice cream, whereas for in the obese group, 24.1% of the women consumed milk and its products and 5.6% regularly consumed fast and fried foods. Evaluation of nutrient intake revealed that the consumption of energy, protein, vitamin A, vitamin $B_1$, $B_2$, $B_6$, niacin, vitamin C, and vitamin E was high in all of the groups, but the intake of folic acid in the underweight group was lower than the required level. Overall, 24.1% of the women in the obese group were found to have metabolic diseases, mostly hypertension (43%). In conclusion, a balanced diet to avoid excessive nutrient intake is needed to prevent obesity.

Three water treatment plants(WTPs) in Jeju island whose source water have different characteristics from those of the mainland of Korea were investigated. Coefficients of bulk water decay($k_b$) of free chlorine at $5^{\circ}C$ for ES, GJ, NW WTPs were $-0.003hr^{-1}$, $-0.002hr^{-1}$ and $-0.001hr^{-1}$ respectively based on bottle tests. To simulate the free chlorine variations in the distribution system using EPANET, ES WTP was chosen. Free chlorine concentrations of several sites were less than the drinking water quality standards(i.e., 0.1 mg/L); E5(0.03 mg/L), E6(0.02 mg/L), W21(0.02 mg/L) and W25(0.03 mg/L). To maintain more than 0.1 mg/L of free chlorine in the distribution system, at least 1.9 mg/L of chlorine was needed at the WTP, which suggested rechlorination was needed to supply palatable tap water to customers. Two sites, one that diverged into E5 and E6 in the east-line and another located before E21 in the west-line were selected for the appropriate rechlorination locations. The recommended rechlorination dosages were 0.42 mg/L for the east and 0.27 mg/L for the west. The simulated results indicated that the free chlorine could be reduced to 0.4 mg/L at the WTP with rechlorination, and taps with excessive free chlorine could be more stabilized(i.e., 0.1~0.4 mg/L).

The purpose of this study was performed to investigate dietary and lifestyle habits, dietary behaviors, and food frequency according to the level of smartphone addiction among 408 university students in Kyungnam province. Statistical analyses were performed using the SPSS software package. Based on using the Smartphone Addiction Poneness Scale, 28.4% were potential-risk smartphone users and while 13.2% were high-risk smartphone users. The levels of depression (P<0.05) and stress (P<0.05) and frequency of snacks (P<0.01) were higher in high-risk and potential-risk groups than in the normal group, and meal frequency was highest in the high-risk group (P<0.01). Percentages of using a smartphone at meal time (P<0.01) and snacking while using a smartphone (P<0.01) were higher in potential-risk and high-risk groups than in the normal group. Percentages of skipping meals (P<0.001) and slow eating speed (P<0.01) due to using a smartphone were higher in high-risk and potential-risk groups than in the normal group, and percentages of taste change (P<0.05) were higher in the high-risk group than in the potential-risk and normal groups. Percentages of exercise reduction (P<0.01), body weight increase (P<0.05), sleep disturbance (P<0.001), and increase in stress (P<0.01) due to using a smartphone were higher in the high-risk group than in the normal group. Scores of dietary behaviors avoiding salty food (P<0.01) and excessive drinking (P<0.001) were higher in the high-risk group than in the normal group. Scores for frequency of oil or nuts (P<0.05) and fatty meats (P<0.01) were highest in the high-risk group. Our results suggest that effective nutrition education programs are needed to solve unhealthy dietary and lifestyle habits from high-risk smartphone users in university students.

Purpose: This study used raw data from the fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) to assess the relationship between vitamin D level and glycemic control of diabetes, and to provide basic data about the use of vitamin D for preparation of a treatment plan for diabetes in South Korea. Methods: For this study, data of 1,713 diabetes from KNHANES (2010-2012) were used. The collected data were analyzed using SPSS 18.0 program, and complex sample frequency analysis, descriptive statistics, complex sample cross analysis, complex sample general linear regression, and complex sample logistic regression analysis were performed. Results: It was found that the poor glycemic control group among the diabetes subjects had significantly lower level of blood vitamin D than the good glycemic control group. Factors affecting glycemic control included drinking, vitamin D levels, hypertriglyceridemia, duration of diabetes, and treatment of diabetes. Also, diabetics with vitamin D deficiency or shortage showed 3.55- and 2.61-times higher odds ratios, respectively, to be diagnosed as the poor glycemic control group than diabetics without vitamin D deficiency or shortage. Conclusion: This study is significant because it provides rationale and basic data about the use of vitamin D for preparation of a treatment plan for diabetes in South Korea by assessing the dependence of glycemic control on the vitamin D level of diabetics. Additionally, future studies are necessary to determine the appropriate concentration of vitamin D for diabetes prevention and treatment to prevent the side effects of excessive supplementation.
