In the present study, in order to improve elementary students’ nutrition knowledge and form correct eating habits, dietitian in charge executed nutrition education for 4th-, 5th- and 6th-grade students at Namchang Elementary School in Suwon, Gyeonggi-do using various educational media for five weeks and two sessions a week (a total of 10 sessions) through discretional activity classes. As for change in nutritional knowledge after nutrition education, 4th-grade students showed improvement by 24.3points(p<0.001), 5th-grade ones by 18.0(p<0.001), and 6th-grade ones by 16.7(p<0.001). With regard to change in dietary habits after education, no effect was observed in the improvement of dietary life but the score of dietary habits was improved as a whole. Nutritional knowledge and dietary habits were in a positive correlation with each other before education(r=0.406, p<0.001), but in no correlation after education. Nutritional knowledge and dietary habit practice plan were in a positive correlation after education(r=0.310, p<0.01). With regard to nutritional knowledge after nutrition education by children’s body type measured using Rohrer Index, knowledge increased significantly in normal children(p<0.001), obese children(p<0.001) and highly obese children(p<0.05) but not in slim children. the effect of education was not significant for children’s dietary habits. Practice plan showed significant changes in all of children(p<0.001). This suggests that nutrition education should be executed from early age. It is necessary to define the goals of systematic nutrition education fit for children’s level and to develop various education programs and teaching materials.

The purpose of this study was to analyze effect of nutrition education after executing education nutrition with the nutrition education textbook, reconstructed 12 units, focused on older elementary school children and to evaluate interest and understanding of textbook. The subjects were 4th grade children. The results were as follows. The most interesting lesson contents was 'obesity(16.3%)', and the next were 'food poisoning' (13.3%), 'kimchi'(13.3%), and 'Korean table manners'(10.2%) in the 12 unit. Children who attended education nutrition answered 'interesting'(94.1%), 'understand easily'(97.1%) about the developed textbook. With regard to change in nutrition knowledge after education, the percentage of correct answers was increased in most of question except 'reason of snack' and 'weight-control'. And the total score of nutrition knowledge was risen(p<0.01), because the ratio of correct answer of 'importance of breakfast'(p<0.05) and 'nutrition labeling'(p<0.01) was improved especially. The ratio of desirable snack time 'between lunch and dinner' was higher after education(91.2%) than before(55.2%)(p<0.01). After education, the choice of 'Fruit and vegetable' of which desirable snack food was increased. Both the choice of 'bread' and 'fast food', a factor of oversupply calorie, was decreased. And after education, the percentage of sound snack place 'home' was improved. In regard of a meal environment, the percentage of 'every wash hand before eating' is 65.1% and there is scarcely change after education. Before education, children answered 'use it rightly'(82.4%) about 'how to eat with spoon and chopsticks', but it is lower after education. The ratio of 'leave food sometimes or always' is 47.1% before education, and the ratio of leftover food tend to decreased in school lunch. Relate to reason of leftover, the percentage of 'because of hate food' tend to decrease. This results suggests that the activity-centered nutrition education can help to change food behaviors and increase nutrition knowledge level of school children.

The radish skin and radish greens are an edible part of the radish. But they are removed before eating the radish and used as a byproduct or an animal feed material because of their tough and rough texture. Melanin is a pigment that gives colour to our skin. But increased production of melanin can turn into benign or malignant tumours. These days due to global warming, the amount of Ultra violet (UVB) rays has been extensively increased with sunlight. Due to this, a phenomenon called exogenous photo aging is widely observed for all skin colour and types. As a result of this phenomenon, a set of enzymes called matrix metalloproteinases (MMP's) that serves as degradation enzymes for extracellular matrix proteins mainly collagen is increased, causing depletion in collagen and resulting in early wrinkles formation. Therefore in our study we used the murine melanoma cell line B16/F10 to study the melanogenesis inhibition by Heated radish extract (HRE) in vitro and we used HRM-2 hair less mice exposed to artificial UVB for checking the efficacy of Heated radish extract in vivo. Furthermore, we prepared a 3% Heated radish extract (HRE) cream and checked its effects on human skin. Our results have clearly demonstrated that Heated radish extract (HRE) have potently suppressed the tyrosinase activity and melanin production in B16/F10 cells. It had also reduced the expression of components involved in melanin production pathway both transcriptionally and transitionally. In in vivo studies, HRE had potently suppressed the expression of MMP's and reduced the wrinkle formation and inhibited collagen degradation. Moreover, on human skin, ginseng cream increased the resilience, skin moisture and enhanced the skin tone. Therefore in light of these findings, we conclude that HRE is an excellent skin whitening and antiaging product.

It has been reported frequently that clinical features of gallstone disease in Korean were similarly changing to those of Occidentals. This changing was thought to be due to Westernized lifestyle and dietary patterns in Korean. The purpose of this study was to investigate the nutritional risk factor among patients with gallstone. The subjects of this study were 90 gallstone group with biliary stone as confirmed by cholecystectomy and 111 control group with no biliary stone as confirmed by ultrasonography adjusted according to age and gender. Anthropometric indices and biomarkers were measured and dietary habit as well as nutrient consumption pattern were investigated using a structured checklist of health-related eating behavior and a semi-quantitative food frequency questionnaire. The mean age was higher in GG (gallbladder stone patient group) than CG (control group). The average BMI and WHR (waisthip ratio) tended to be higher than those in CG. WC (waist circumference) and WHR of women in GG were significantly higher than in CG. GG had lower levels in TC (p < 0.01), LDL-C (p < 0.05), and HDL-C (p < 0.05), but higher FBG levels (p < 0.001). GG tended to be associated with lower physical activity and more frequent consumption of meat, meats with high fat and high sugar content food. The consumption levels of fiber (p < 0.05), vitamin C (p < 0.05), calcium (p < 0.01) in GG were significantly lower than in CG. These findings showed that the association with incidence of gallbladder stone and anthrophometric indices and dietary consumption patterns. Further study may be necessary to elucidate the dietary risk factors in the changing patterns of gallstone disease.

Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

Objects. There was an increase in obese population due to eating habits resulted in modernization of lifestyle and the change of the tendency to conduct the physical activity, in order words, the reduction in the range of kinetic energy. Obesity is viewed as a major risk factor for serious health problems, including heart disease, high blood pressure, stroke, diabetes, and certain forms of cancer as well as for psychological and social problems owing to our fat-phobic society. In the present study, we investigate the weight loss thanks to giving Handayulso-tang(HD) medication of Taeum-in to induced obesity rats and its effects on lipid metabolism, given that their behavior patterns are changed according to their constitution. Methods: The extracts of Handayulso-tang was orally administered to the rats of HD group 200mg/200g of rats weight every day for 6 weeks, and the control group were fed with equal amount of saline. And measured the body weight and total cholesterol, triglyceride, free fatty acid and total lipid contents in serum in obese rats. Results: 1. The body weight in HD group were decreased. 2. The contents of serum total cholesterol and triglyceride in HD group were decreased and statistically showed the significant difference compared with the control group. 3. The contents of serum free fatty acid and total lipid in HD group were decreased, but did not statistically show the significant difference compared with the control group. Conclusion: Based on the above results, we know that Handayulso-tang have effects on the decrease of the body weight and the contents of serum total cholesterol, triglyceride, free fatty acid and total lipid So it could be concluded that Handayulso-tang can help the treatment of obesity.

In recent years, there has been an increase in the morbidity of gastritis in Korea due to lifestyle factors mostly changes in eating habits and stress. Gastritis is more likely to progress to gastric cancer, and therefore it is important to prevent and manage gastritis through lifestyle adjustment and treatment at an early stage. In this study, cabbage, which was found to be effective in gastritis, was mixed and fermented with other crucifer plants such as kale and broccoli to evaluate the overall efficacy of fermented brassica puree on alcoholic acute gastritis. Based on our results, fermented brassica puree alleviated gastric injury induced by 150 mM HCl/60% ethanol. In addition, it was confirmed that PGE₂, a gastric mucosal protective factor, was increased, and other positive effects such as an increase of MUC1 and regulation of PKC were observed. The results of this study suggest that fermented brassica puree can relieve acute alcoholic gastritis by regulating PGE and the expression of MUC1, a gene related to mucus secretion, and activating PKC, which is related to mucosal cell activity.

Purpose: This study was performed to investigate the dietary behaviors and stress-related factors among male and female college students. Methods: A total of 405 college students (male-195, female-210) were recruited, of whom a questionnaire-based survey was conducted. The study investigated the general characteristics, health-related factors, dietary behaviors, and stress-related factors of the respondents. Results: The body mass index was significantly higher in males. The rates of underweight and overweight were significantly different between male and female respondents. The scores for workout frequency, health concerns and health condition were significantly higher in males, while the score for watching TV & playing computer games was significantly higher in females. The scores for meal regularity, frequency of breakfast consumption, and smoking were significantly higher in males. Eating problems showed a significant difference between males and females. The biggest source of stress was social factors, followed by college study and individual factors and the most experienced stress-induced symptom was anxiety, followed by headache and stomachache. The most popular way to overcome stress was taking a rest, followed by drinking & smoking and outdoor activity. The most preferred food under stressful conditions were alcohol or beverages, followed by hot & spicy food and sweet food, which showed a significant difference between males and females. Conclusion: These results indicate that stress affects dietary behaviors, drinking, smoking, and health status. Stress not only changes dietary behaviors, but is also related to health status. Therefore, it is necessary to develop appropriate programs for emotional stability and stress relief targeting college students which provide continuous nutrition education focused on desirable dietary behaviors and nutritional aspects.

BACKGROUND/OBJECTIVES: The intake of sugar has increased worldwide, and it is well established that childhood experiences and food preferences affect lifelong eating habits. To discourage sugar intake, nutrition education was imparted, and the effectiveness of the nutrition education program was investigated by considering the nutrient density and major dietary sources of sugar intake. SUBJECTS/METHODS: Twenty four-hour dietary recall and sugar intake frequency of 96 pre-school children (educated n = 47; non-educated n = 49) were collected on 3 consecutive days (1 weekend day, 2 weekdays) after 11 weeks of imparting nutrition education. Dietary intake of nutrients and total sugar were analyzed, and the intake frequency of sugar source foods were identified. All nutrition education programs were focused on a hands-on education program, and consisted of cooking lab, play, activity, animation, and visual materials. The difference between the two groups was verified by the Chi-square test or t-test. All statistical analysis was performed with significance level at P < 0.05. RESULTS: Compared to the non-educated group, the intakes of protein (P < 0.001), fiber (P < 0.01), potassium (P < 0.05), iron (P < 0.05), zinc (P < 0.05), and iodine (P < 0.001) were significantly higher, and the intakes of carbohydrate (P < 0.01) and total sugar (P < 0.05) were significantly lower in the educated group. The cumulative percent of sugar intake of top 20 sugar source foods in the educated group (82.80%) was lower than that of the non-educated group (85.75%). The contribution of beverages on total sugar intake was lower in the educated group. The average frequency of consuming sugary foods was significantly lower in the educated group (P < 0.05). CONCLUSIONS: Our results indicate that nutrition education on discouraging sugar intake is effective in reducing the amount of total sugar consumed, resulting higher nutrient density in the diets of pre-school children.

Objectives: This study examined the Korean elderly's dietary intake status, subjective health-related perception and chronic disease prevalence among age groups. Associations of dietary quality with subjective health-related perception and chronic diseases were also examined. Methods: Based on data from the 7th National Health and Nutrition Examination Survey, a total of 3,231 elderly were selected and categorized into 4 age groups of '65 ~ 69', '70 ~ 74', '75 ~ 79' and 'over 80'. Nutrient intakes, proportions of those with insufficient nutrient intakes, Korean Healthy Eating Index (KHEI), some subjective health-related perceptions and prevalence of major chronic diseases were compared according to the age groups. Differences in the subjective health-related perceptions and odds ratios of the chronic diseases according to the quartile levels of KHEI within the same age group were analyzed. Results: With the increase of age, several nutrient intakes (P < 0.001) and KHEI scores significantly decreased (P < 0.01). In women, activity restriction increased (P < 0.05), and EQ-5D score decreased with age (P < 0.001). Prevalence of hypertension (P < 0.0001), hypercholesterolemia (P < 0.05) and anemia (P < 0.01) significantly increased, while hypertriglyceridemia (P < 0.01) significantly decreased only in men. Obesity prevalence decreased, while underweight prevalence increased (P < 0.05). Subjective health status, EQ-5D score and PHQ-9 score significantly improved as KHEI score increased in certain age groups of women (P < 0.05). Odds ratio of hypercholesterolemia significantly increased with the increase of KHEI score in 65 ~ 69-year-old women. However, hypertension and anemia significantly decreased with the increase of KHEI score in 75 ~ 79-year-old women (P < 0.05). Conclusions: The study findings suggest that nutrition management and policy for the Korean elderly need to apply a segmented age standard that can better reflect their dynamic characteristics.
