This study aims to investigate the nutritional status of night eaters using the data from 2005 Korean National Health and Nutrition Examination Survey. A total of 3,903 subjects aged 20 and above were divided into 3 groups by using 24-hr recall data according to the night snack calorie intake: non-night snack, night snack less than 500 kcal and 500 kcal and more. Their data were analyzed to find out the difference on the socio-demographic, anthropometric, blood pressure, blood parameters and dietary characteristics. Among the subjects, non-night eaters were 66.0%, night eaters of less than 500 kcal were 28.4% and 500 kcal and above were 5.6%. Male adults, young-aged, higher educated, higher income earner, breakfast skipper and frequent dine-outer (3 times and more a day) were found more in the night eaters with 500 kcal and above. Night eaters above 500 kcal showed higher waist circumference, Glu-FBS, Glu-PP120 and also showed higher daily intake of fat and alcohol per 1,000 kcal and food groups of meat & eggs, beverages and alcohol drinks (p < 0.05), while they showed the lowest carbohydrate energy ratio of $58.3{\pm}13.7$ among the three groups. These results suggest that habitual night snack intake above 500 kcal could lead to abdominal obesity and diabetes due to higher intake of meat, fat and alcohol.

BACKGROUND: The purpose of this study was to evaluate ecological function of small-scale pond and movement characteristics of mudfish (Misgurnus mizolepis) during midsummer drainage period. METHODS AND RESULTS: In situ experiments were performed in the paddy field with mudfish under the condition of midsummer drainage from 13 July to 29 July 2010. The mudfish used in this experiment is approximately 1,000 individuals with a cut tail. Mudfishs were released in the rice field before midsummer drainage and caught again in the small-scale pond and the paddy field after midsummer drainage. Results showed that the abundance of mudfish was higher in drainage canal than small-scale pond at the early stage of midsummer drainage, because flow was formed toward the drainage canal. In that time, 3% of the total marked mudfish were captured at outlet of drainage canal. As the paddy was drying, 5% of total marked mudfish moved to the small-scale pond during midsummer drainage period. Contrary to the general hypothesis, the marked mudfish was not found in holes in paddy field.of total caught in the small-scale pond ingested mainly animal prey, and it's frequency of empcy stomach was 10%.oOn the other hand, all m total collected in the paddy field showed empcy stomach. It was apparent from the experiment that m total are eeldng normally in the small-scale pond, while m total are not eat properly in paddy field. CONCLUSION(s): As the paddy was drying, mudfish moved to the small-scale pond during midsummer drainage period but mudfish was not found in holes in paddy field. It can be concluded that small-scale provides a shelter and prey to mudfish in the midsummer drainage period.

This study was intended to collect the baseline information on health status, nutrient intakes and dietary self-efficacy according to the obesity levels of male workers. Nutrient intakes of 224 male workers were assessed by 24 hr recall method; also, dietary attitude and dietary self-efficacy were investigated by self-administerd questionnaires. Biochemical characteristics such as blood pressure (SBP, DBP), total cholesterol(TC), hemoglobin (Hb), blood glucose (BG), SGOT, SGPT and ${\gamma}-GTP$ were assessed. Subjects were divided into normal, overweight and obese groups by body mass index (BMI). The health status was analyzed as normal group, health concerned group and disease suspected group. Weight, percent ideal body weight (PIBW), BMI and body circumference (waist, hip) and waist-hip ratio were high in the order of obese group, overweight group and normal group. Body fat mass was high also in the order of obese, overweight and normal group. Blood pressure (SBP, DBP) was the highest in obese group. SGOT, SGPT, ${\gamma}-GTP$ were higher in the obese group than normal and overweight groups. It was Proven that the percentage of those evaluated as low nutrient intakes were 71% for Ca, 50.9% for Zn, 70.5% for vitamin B2, 56.3% for vitamin C and 81.3% for folic acid. The dietary attitude scores were high according to the dietary self-efficacy. The age was positively correlated with dietary attitude, and the dietary attitude was positively correlated with dietary self-efficacy and total energy intakes. Dietary attitude showed the greatest total causal effect in relation to dietary self-efficacy. The results of this study showed some health problems and nutritional problems, indicating the need for nutritional management for male workers.

This study was performed to identify association between nutritional status and health risks of the elderly. This was a cross-sectional study involving low income elderly women in Gwangju, Korea (${\geq}$65y, n = 92). Socio-demographics, life style characteristics, health conditions, dietary intakes based on 24h-recall method, anthropometric measures, and clinical biochemistry parameters were examined. Anthropometric and clinical parameters included wt, ht, waist, hip, body protein, body fat, abdominal fat, total cholesterol, HDL-cholesterol, triglyceride, total protein, albumin, hemoglobin, hematocrit, fasting blood glucose, ferritin, IL-2, IL-6, TNF-${\alpha}$, CRP, TAS, TBARS, systolic blood pressure, and diastolic blood pressure. The subjects were divided into three groups based on age (65-74y, 75-84y, 85y${\leq}$) and were divided into two groups according to the sum of the Nutrition Screening Initiative (NSI) checklist score (adequate nutritional status, NSI score ${\leq}$3; at risk of malnutrition, NSI score >3). Mean and frequency of variables were estimated. Analysis of Variance, Tukey test, Chi-square test, and Multiple linear regression analyses were performed. Mean BMI and body fat were 25.1 $kg/m^2$ and 40.0%, respectively. However, for over 80% of subjects, the intakes of energy, fiber, thiamin, riboflavin, niacin, folate, Ca, K, and Zn were less than the Korean DRI (EAR or AI). The subjects who had lower NSI score tended to have better health status, eat meals frequently, have less depression, and exercise regularly. The subjects who had higher NSI score tended to have tooth problems, to eat alone most of time, and to be physically unable to cook or feed. Serum IL-6 and TNF-${\alpha}$ were significantly related with nutritional status which suggested higher tendency of inflammatory response. Serum IL-2, TAS, and glucose were significantly correlated with body fat (%) or abdominal fat (%). These results suggest that improving the nutritional status, increasing regular exercise, maintaining normal weight are beneficial to health care of low income elderly women.

This study was performed to identify the association between the metabolic syndrome and the biochemical measurements and nutrient intakes. A total of 1,431 people (533 males, 898 females) aged over 45 years living in Andong rural area participated in this study in 2003. Plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), $\gamma$-glutamyl transferase ($\gamma$-GT) and thiobarbituric acid reactive substances (TBARS) levels in metabolic syndrome were significantly higher than those in normal group. In multiple logistic regression, those biochemical measurements were found to be positively associated with the metabolic syndrome as the adjusted odds ratios (OR) 1.839 (p<0.001) by AST, 2.302 (p<0.01) by ALT, 2.143 (p<0.001) by $\gamma$-GT, and 1.874 (p<0.001) by TBARS. We also found that the increased level of those measurements tended to be strongly associated with high triglyceride among the metabolic syndrome components. However, the nutrient intakes between the metabolic syndrome and the normal group were not significantly different. Also, we could not find any nutrient intakes significantly associated with the metabolic syndrome, except high carbohydrate intake (>70% of kcal) compared to normal intake (55~70% of kcal) showed OR 0.781 (p<0.05). In analyzing the association of nutrient intakes with metabolic syndrome components, we found that the calorie intake was negatively associated with abdominal obesity (OR 0.696, p<0.05) and high fat intake (>25% of kcal) was positively associated with low HDL-cholesterol (OR 1.864, p<0.05). This study revealed that the biochemical measurements, such as plasma AST, ALT, $\gamma$-GT, and TBARS, are associated with metabolic syndrome, but considering the nutrient intakes, we suggest that further studies are needed to identify the associations.

Q-35의 일회 및 반복투여 연구결과, 자타학 증상은 단지반복투여 피험자에서 중등도의 두통(1예)과 설사(3예)가 관찰되었으나 이들 설사증례는 장내 세균총 검사상 복감염에 의한 것이 아니었다. Q-35 투여 후 Q-EEG 및 평행기능의 장애 등은 관찰되지 않았으며 임상화학 검사상 반복투여 3예에서 SGOT, SGPT의 경미한 상승을 보였으나 이러한 변화는 정상 범위내에서의 변화이었다. Q-35의 반복투여에 따라 투약 3일에서 8일에 걸처 장내세균총은 일부 호기성 및 혐기성 세균총의 감소를 보였으나 투약종료 10일 후에는 투약전 상태로 회복되었다. Q-35는 투여량의 약 70 % 가 24시간 뇨중으로 배설되었으며 일회 및 반복투여의 결과 용량의존적인 동태양상은 관찰할 수 없었다. 50 mg에서 400 mg까지 일회 투여시 5.6-7.1 시간의 혈장반감기를 보였으며, 반복투여 시험에서는 평균 5.6 $\pm$ 0.7 시간의 반감기를 보였다. Q-35는 타액내로 신속히 이행되었으며 타액내 AUC는 혈장 AUC의 약 75 %에 해당하였고, 식사에 의해 약간의 흡수속도지연(Cmax 0.4 시간지연)과 공복시에 비해 82 %의 상대적 생체이용율을 보였다.

This study aimed to identify the self-rated health and its associated factors of the elderly. Study subjects were community-dwelling elderly of 60 or more. Survey was done by using questionnaire including general characteristics, lifestyle, and health related variables. Blood pressure, anthropometric variables, lipid profiles, and fasting glucose were checked. Descriptive statistics showed that good self-rated health was 78.2% in the elderly. Multiple logistic regressions revealed that good self-rated health was associated with disease(OR:10.83, 95% CI:2.47-47.43), depression(OR=2.50, 95% CI=1.20-5.18), and exercise(OR=3.01, 95% CI=1.40-6.47). Therefore, health promotion program considering associated factors of self-rated health should be developed.

This study was performed to assess the risk factors associated with hypertension from Jan/2003 to Feb/2003. The subjects were 1,296 people (496 males, 800 females) aged 40 years and over living in Andong rural area. The hypertensive group was composed of 602 people (272 males, 330 females), who were diagnosed as hypertension ($SBP{\geq}140\;mmHg$ or $DBP{\geq}90\;mmHg$) for the first time at this health examination. The mean anthropometric values of body weight, body fat (%), body mass index (BMI) and waist circumference were significantly higher in hypertensive group than those in normal group. However, the biochemical measurements such as total-cholesterol (TC), triglyceride (TG), HDL-C, LDL-C and fasting blood glucose (FBG) levels did not show any difference between two groups except TG in female. The risk factors of interest in the development of hypertension were analyzed using the multiple logistic regression and expressed as odds ratio (OR) and 95% confidential interval (CI). The results showed that age, sex, obesity, waist circumference, alcohol drinking and meat intakes were risk factors for hypertension. In contrast, cigarette smoking, exercise and the increased fish, fruit and vegetable (except Kimchi) consumption, blood lipid levels and FBG were not linked with the development of hypertension. Nutrient intakes were not associated with hypertension, either. In conclusion, we cannot assert that this study established the existence of the cause-and-effect relationship between nutrient intakes and risk of hypertension in the subjects, but it does suggest that this is a question worth investigating further using a larger scale of case-control study to determine how the past exposure to some nutrient or dietary component relates to the development of the disease.

This study was to designed to investigate the effects of nutrition education and exercise program for overweight or obese female adults, and also emphasize the necessity of a proper nutrition education. The anthropometric characteristics, nutritional intake, eating habit, and hematological index, physical examination were measured before and after program. Considering the time schedule of the subjects, the exercise program was divided into 3 sessions (morning, afternoon, and evening) and the subjects performed swimming and weight training for 4 weeks. The subjects were overweight or obese women, with an average age and height of each 46.1 and 156.3 cm. The weight and BMI were decreased significantly after nutrition education and exercise program. The back region of front arm (p<0.001), infrascapular region (p<0.001), body fat (p<0.001) were significantly decreased, and grasping power (p<0.01), back muscle power (p<0.001) were significantly increased after nutritional and exercise program. Total triglyceride level and fasting blood glucose (p<0.001) were decreased significantly after program. The intakes of vitamin D and vitamin $B_1$ were significantly changed after nutrition and exercise program. As for eating behavior and nutritional knowledge evaluation after program, the average score increased significantly (p<0.001). The results of this study show that this nutrition and exercise program can be an effective approach to improve their hematological index and nutritional and health status.

Purpose: In this study, we investigated the effects of jaceosidin on blood glucose regulation in type 1 diabetic mice. Methods: C57BL/6 mice were divided into four groups; normal control (Normal), diabetes control (D-Control), diabetes low-jaceosidin (D-0.005%), and diabetes high-jaceosidin (D-0.02%). Type 1 diabetes was induced by streptozotocin and mice were then fed a diet containing jaceosidin for eight weeks. Fasting blood glucose, oral glucose tolerance test, insulin tolerance test, lipid peroxidation, and antioxidant enzyme activities were assessed. Results: Jaceosidin supplementation for eight weeks had no effect on body weight, organ weight, and blood lipid profiles. However, jaceosidin supplementation significantly lowered fasting blood glucose level and reduced insulin resistance. We also found that jaceosidin supplementation increased antioxidant capacity by enhancement of catalase and GSH-px activities. Conclusion: These results suggest that jaceosidin could be a therapeutic candidate to ameliorate hyperglycemia through increase of antioxidant enzyme activity.
