This study was conducted to examine the effect of children's dietary quality, dietary habits, food behavior and health-related lifestyles according to the mother's lifestyles of health and sustainability (LOHAS). The subjects were 580 children. Mother's LOHAS attitude index was 66.85 points and 100 points was a perfect score. The mother's high LOHAS attitude items that children perceived were "My mother often communicates with the family"(3.99 points) and "My mother thinks that the family's health is more important than her health"(3.93 points). In contrast, the LOHAS attitude items for "My mother does community service activity on weekends"(2.78 points), and "My mother participates in environmental protection service activity for the local community"(2.78 points) were very low. The high LOHAS behavior index of mothers was "resource saving", whereas "social welfare" scored low. When self-perceived health status and monthly income of children was high, the mother's LOHAS score was high. The LOHAS attitude index of mothers had a meaningful impact on the children's dietary quality, dietary habits, food behavior and health-related lifestyles. The most frequent food behavior variables were "high skipping rate", "frequency of snacks is 2~4 times per week", "speed of eating is rapid", and 'meals' amount is sufficient. The highest daily life habits item was "I try to maintain a pleasant and enjoyable life style"(3.42 points). The highest nutrient intake attitude score was "I tend to eat rice everyday."(3.41 points). They were highly recognized with "moderate physical activity", "high exercise preference", "positive posture exercise", "exercise <2 days per week", and "over 30 minutes exercise time per day" for the exercise performance status items. It was verified that the higher mother's LOHAS lifestyle score is, the higher children's food behavior, daily life habits, nutrient intake, exercise performance state score are.

This study was done to compare nutrient intakes, anthropometric indices, and psychosocial factors related to smoking by smoking status among adolescent girls in Seoul. Subjects were high school students, and smokers were 17.6%. Nutrient intakes were analyzed by convenient method, and anthropometric measurements were done by Inbody 2.0. Psychosocial factors of smoking were examined based on the Theory of Planned Behavior : 26 attitudinal, 9 normative, and 17 control beliefs were used. Smokers smoked 5-7 cigarettes a day on average, with 1.26 pack-years of smoking, There were no significant differences in anthropometric characteristics, except fat distribution, between smoking(n=92) and nonsmoking(n=92) and nonsmoking(n=94) group. The percentage of alcohol groups. Especially, caloric intake (63.6% of RDA) were much below the recommended level. With respect to psychosocial factors, 18 out of 26 attitudinal beliefs were significantly different between smokers and nonsmokers. Smokers responded less negatively on the items of bad health effects of relax(p<0.001). In addition, smokers were more convinced of advantages of smoking (test, etc.)but responded less negatively on the disadvantages of smoking(bothering others, yellow teeth, bad breath, etc.). Smokers expressed less pressure for not smoking from siblings, friends, school seniors than nonsmokers. In addition, smokers, expressed less confidence in controlling the urge to smoker or quitting smoking in several situations, such as 'after a meal', 'feel bored', 'with friends', 'when angry' offered a cigarette by friends', 'drinking coffee or tea', 'drinking alcohol', 'seeing others smoke'(p<0.001). Smokers also felt less developing in applying specific skills for controlling the urge to smoker or quitting smoking. These findings suggest the need for developing smoking cessation programs for adolescent females, focusing on specific beliefs identified in this study.

Objectives: This study aimed to investigate arterial stiffness index, physical activity, and food and nutrient intake in middle-aged adults over 40 years when the incidence of cardiovascular disease begins to increase. Methods: This study included 106 subjects (48 males and 58 females) aged between 40 and 64 years. The arterial stiffness index (brachial-ankle pulse wave velocity [baPWV], and ankle-brachial index [ABI]) were measured using a blood pressure pulse wave testing device. Physical activity was assessed using the Korean version of the Global Physical Activity Questionnaire, and food and nutrient intake was calculated using the Food Frequency Questionnaire. Results: The mean age of the subjects was 54.4 years. Although the ABI of the subjects was within the normal range, they were divided into tertiles to compare physical activity and food and nutrient intake. In males, the time spent on moderate to vigorous physical activity (MVPA) was significantly higher in T3 (600.6 min/week) than in T1 (304.4 min/week). In females, the time spent in sedentary behavior was significantly lower in T3 (294.5 min/week) than in T1 (472.1 min/week). In addition, the frequency of fish consumption was significantly higher in T3 (1.27 frequency/day) than in T1 (0.64 frequency/day) in females. Polyunsaturated fatty acid (PUFA) and ω-3 fatty acid intake, adjusted for energy intake, were significantly positively correlated with ABI (r = 0.200 and r = 0.218, respectively). Conclusions: High MVPA (in males), low sedentary behavior (in females), and PUFA and ω-3 fatty acid intake through fish consumption may be associated with low peripheral artery stiffness. Therefore, arteriosclerosis can be prevented through physical activity and proper dietary therapy.

The purpose of this study was to determine eating behaviors and nutrient intakes of 256 third grade primary school children(134:boys, 122:girls) in Kwangju. There were no significant differences in the heights, weights, physical circumferences measurements between the boys and girls, but the skinfold thickness measurements were significantly different. Most nutrient intakes were higher than the Rec ommended Dietary Allowances but the intake of energy, calcium, and vitamin E were lower than the RDA. The intakes of calcium, niacin, and vitamin E of the girls were significantly lower than those of the boys. With regard to meal volume, 13.6% of the subjects has been 'much'. With regard to meal speed, 24.6% of the subjects has been 'fast'. The study also found that 50% of the subjects skipped breakfast, 67.6% of the subjects had irregular meal times, 64.6% of the subjects ate snacks after dinner and 85.9% of the subjects ate snacks. These results show that the nutrient intake of children was related to snack eating more than regular meals. With regard to dietary behavior and nutrient intakes, meal volume, meal speed, skipping breakfast, eating snacks and eating snacks after dinner were major influences. But regularity of meal time was not influence on nutrient intakes. These results suggest that children's eating behaviors are in needs of correction. This reasserts the importance of nutrition education to children through teachers, parents and dietitians. The findings of this study should be applied to nutrition education to ensure better physical fitness of children.

The purpose of this study was to investigate nutrient intake and food behavior according to the nutrition knowledge of middle school students residing in Seoul and Kyunggi-do, Korea. Anthropometric measurements and questionnaires, including 24-hr recall of dietary intake, were collected from 543 male and female middle school students. They were assigned to one of five groups according to their nutrition knowledge : very high group (VHG ; 90 - 100 score), high group (HG ; 80 - 90 score), normal group (NG ; 70 - 80 score), low group (LG ; 60 - 70 score) and very low group (VLG ; < 60 score), and comparisons were made. The mean age of the subjects was 13.7 years old. The mean height, weight, and BMI of male and female students were 161.9 cm, 52.6 kg and 20.2 kg/$m^2$, 157.0 cm, 50.4 kg, and 20.4 kg/$m^2$ respectively. Female students skip breakfast and dinner more frequently than male students do. Male students skipp lunch and eat fast foods more frequently than females do. Protein, calcium, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C, fat, and animal protein intakes in females are shown to be related to their nutrition knowledge. Calcium, protein, animal protein, vitamin B$_2$and niacin intakes are significantly lower in the VLG than in the others. However, vitamin B$_1$and vitamin C intakes are significantly lower both in VHG and VLG. Fat intake in VHG is lowest. Nutrition knowledge of male students is correlated with mothers knowledge, nutrition attitude and nutritional status. On the other hand, in female students, nutrient consumption was lowest in subjects whose nutrition knowledge was highest and lowest. Therefore, nutrient consumption is affected by nutrition knowledge. However, in female students, possibly due to wrong information on diet or prejudice and outlook, nutrient consumption was low even when they scored high in nutrition knowledge. In conclusion, nutrition knowledge of male students is affected by the mothers nutritional knowledge and attitude. Therefore, nutrition education for mothers is very important. In male students, as their nutrition knowledge is low, their nutrient consumption is affect. These results indicate nutrition education and correct information for body image, balanced diet, regularity of meals and food selection for middle school students are required at both school and home.

The purpose of this study was to investigate the relationship among eating habits, eating behaviors, obesity indices and serum leptin levels of 97 school children in the Daegu and Kyungpuk areas. The subjects consisted of 42 boys and 55 girls from the 4th and 5th grades. The prevalence rate of obesity was 63.6% in the males and 36.4% in the females. The nutritional status of the subjects was assessed using 24-hour dietary recalls and blood analyses. The mean serum leptin levels of the obese group (12.84 $\pm$ 6.97 ng/ml) were significantly higher than those of the non-obese group (2.43 $\pm$ 1.53 ng/ml) (p < 0.001) . The mean eating behavior scores and MAR were significantly different in the two groups. Nutrient intakes were low and fell short of the RDA. Serum leptin levels showed a significant negative correlation with eating habit (r= -0.24) and eating behavior scores (r= -0.40) (p < 0.05, p < 0.001). It was speculated that nutritional intervention and education about the appropriate nutrient intake requirements of developing children might be necessary.

Net outflow flux and unit load of pollutants were investigated at a paddy fields area(Soro-ri) with large-scaled plots on loam soil during irrigation seasons of $2001\~2003$. Water samples were collected, and inflow and outflow were .measured at $5\~10$ day intervals during non-storm periods and at $2\~6$ hours intervals during storm events. The average concentration of TP in percolated water was much smaller than that in irrigation and surface outflow water likely due to phosphorus absorption capacity of paddy soils. Net outflow flux in study area was significantly correlated with rainfall and surface outflow discharge. Nutrient flux from Paddy fields can be abated by reduction in outflow surface discharge.

The objective of this study was to evaluate the GLEAMS-PADDY model by applying it to estimate nutrients loading from paddy-field areas. Field data from Soro region of Chungbuk province during May to September 1999 were used for model application. Field data collected include the amounts of rainfall, irrigation water, drainage water, ET, and Percolation in hydrology Part. T-N and T-P concentrations in the rain water, irrigation water, ponded water, drainage water and percolated water were measured. The comparisons of observed and simulated water balance components and nutrient concentrations showed reasonably good agreements and the GLEAMS-PADDY model may be used to simulate nutrients loading from paddy fields. Futher research was suggested to include the erosion submodel in the GLEAMS-PADDY model to better simulate the nutrient behavior. In addition, the pesticide submodel also recommended to be included in order to simulate the various pesticide applied in paddy fields.
