Carbohydrate intake is decreasing along with the reduction of rice consumption among the Korean population. There is an increasing trend of diet-related degenerative diseases with the increased consumption of animal food, and therefore, the increase of animal food intake can be considered as one of causes of the diet-related disease. The objective of this study is to investigate the differences in rice preference and breakfast patterns between the subjects have breakfast regularly and those skipping it. One thousand participants were selected by the stratified sample method from the primary, middle, high school and college, and company workers from 24 cities of Kyeonggi-do. The interviewing procedure was carried by regional home extension workers. Approximately half participants (49.9％) were under the age of 20. Although 86％ of the subjects considered eating breakfast good for health. only 46.4％ of the subjects had breakfast regularly (HB). The rest of them skipped breakfast (SB) more than twice a week. The proportion of subjects hiving no breakfast were 9.3％ of male and 12.2％ of female subjects. The main reason for not having breakfast was due to the limited time. For their breakfast 85％ of the HB ate boiled rice with the side dishes. More subjects in SB (27.8％) preferred the boiled rice with various grains for breakfast than those of HB (21.8％). The subjects in HB (65.5％) preferred boiled plein rice more than those of SB (56.9％). In cases they must have breakfast, 47.7％ of the subjects wanted rice with the side dishes,24.2％ preferred rice ball or rice roll with laver, 10.5％ preferred a rice beverage. More subjects in HB (59.8％) wanted rice with side dishes than those in SB (36.9％). It was found out that selecting rice at the breakfast is still the main choice. Diverse ready-to-eat rice menus have to be developed to increase the rice consumption, specially to increase breakfast eating frequencies of SB through saving time and effort.

Effect on iron dissolution from iron sauce pans treated with the acetic, malic, citric acid and concentration(0. 0.02. 0.04. 0.1, 0.2, 0.4. 1.0, 2.0, 4.0%) of acidity, boiling times(0, 10. 20, 30, 40, 50, 60mins.) and temperature(5, 20, 40. 60, 80, 10$0^{\circ}C$) of acidity solution and in new and used sauce pans was investigated. As acetic acid concentration increases, iron content has increased. Iron dissolution concentration from iron sauce pan for boiling in malic acid increased more than that of acetic acid and citric acid. At above 6$0^{\circ}C$, as temperature increases, concentration of iron dissolved from iron sauce pan has increased. As boiling time increases, concentration of iron dissolved from iron sauce pan has also increased. Concentration of iron by repeated use has increased. And iron concentration has dissolved in large amount from new pan rather than used pan. Concentration of iron with distilled water by repeated use has increased only slightly. But 1% acetic acid has dissolved in large quantities.

The informations concerning knowledge, value and consumption pattern for rice foods of elementary schoolchildren (630 boys and 550 girls in 5th or 6th grade) were investigated in Changwon and Gimhae of Gyeongnam province. They were asked based on knowledge, one’s value and intake frequence of rice foods by questionnaries. Menus for 3 days including 2 weekdays and 1 weekend day were taken from 136 students (77 boys and 59 girls) in two Elementary Schools in Changwon and Gimhae to know intake reality of rice product. The purpose of this survey was to find the way of encouraging rice intake and preference which now seemed to be low because of simplified, westernized eating habits, and to provide basic information needed for inheriting and improving our traditional cooked rice centered eating culture. The results are summarized as follows. The knowledge of rice was positively correlated to the one’s value (r=0.365, p<0.001) and the preference (r=0.132, p<0.001), the one’s value was positively correlated to preference (r=0.409, p<0.001). The score of knowledge for rice was 12.8 points out of 20, the girls get points(13.12) significantly higher than the boys (12.53) (p<0.01). One's value about rice foods was 37.35 points out of 50 what is relatively high. They have eaten cooked rice type food for 2.24 times per day. Both boys and girls in Changwon and Gimhae area were having cooked rice type food significantly more during weekdays compared to weekends (p<0.001) by 3 days food record. According the results, we can see the possibility that schoolchildren can be encouraged to eat more rice foods by nutritional education to go with the development of various programs.

This study researched the dietary habit of boy's and girl's high school students, and into low it was connected with the state of health between the group of having the right dietary habit and the group of having the wrong habit. Results were as follows: 1. The age about the object person of research was the most numerous in 79% at 16~17 years old, the average weight was $55.67\pm9.08$kg, the average height was $165.47\pm7.56$cm. 2. In the parent's school career of the object person of research, persons who graduated high school were many. The mother's educational level was lower than the father's school career. The parent's school career in the district south of a river was higher than the parent's school career in the district north of a river. And the parent's school career of cultural students was high. 3. The frequency of food intake in the district north of a river and in the district south of a river was a meaningful difference in the vegetables blended in green and yellow things (p<.01), fruit (p<.05), rice, flour, potatoes (p<.05), and so the district north of a river took less than the district south of a river. 4. The most regular diet in a day was lunch. The appetite of the students was generally good. 5. The general environment and state of health were a meaningful difference about melancholia (p<.05) in the district of north and south of river, and so melancholia in students of the north of a river was high. 6. The state of health according to regular diet was a meaningful difference, so regular student was better than irregular student in state of health, and was the same in study. 7. Eating habit correlated much to each state of health, Especially in physical health, the muscular frame correlated to fruit (p<.001), seaweeds (p<.05), fried food, jun, panbroiled food (p<.05), salty taste (p<.05), sour taste(p<.001).

This study evaluated the characteristics of rice cookies with varying amounts (0, 250, 500, and 750 mg) of dandelion complex powder. Dandelion powder is considered a functional food with skin-moisturizing and atopic skin improvement effects by KFDA. Quality characteristics of AF343 and rice cookies were measured by determining antimicrobial activities, physical characteristics, sensory evaluation values, and antioxidant activities. An antibiotic susceptibility test of the powder showed positive activities in Escherichia coli (O157:H7), Staphylococcus aureus, Bacillus cereus, and Listeria monocytogenes. Rice cookie containing 250-500 mg powder showed significantly increased antioxidant activities compared to controls (p<0.05). However, sensory intensities between the two sample groups were not significantly different. Thus, rice cookies containing 250-500 mg dandelion complex powder were successfully developed to improve antioxidant and antimicrobial qualities. These products may attract the attention of health-conscious consumers in the highly competitive cookie industry.

Heavy metal pollution may be one of the most serious challenges confront crop production and human health. Therefore, the selection of heavy metal tolerance cultivars which adapted to the contaminated fields will introduced a suitable solution for management this critical environmental risk. The objectives of this research is to assess human health risk using geochemical analyses and exposure assessment of heavy metals in rice cultivars. Risk for inhabitants in the closed mine area was comparatively assessed for As, Cd, Cu and Pb in 10 rice varieties as a major exposure pathway. The average daily dose (ADD) of each heavy metal was estimated by analyzing the exposure pathways to rice and soil. For the non-carcinogenic risk characterization, Hazard Quotient (HQ) and Hazard Index (HI) were calculated using toxicity indices provided by US-EPA IRIS. The different rice varieties revealed a wide range of HI values from 23.6 to 34.3, indicating that all rice varieties have a high potential toxic risk. The DA rice variety showed the lowest HI value while the TB rice variety the highest. The probabilities of cancer risk for As via rice consumption were varied with rice varieties ranging from 2.0E-03 to 3.5E-03 which exceeded the regulatory acceptable risk of 1 in 10,000 set by US-EPA. The DA rice variety also showed the lowest value while the TB rice variety gave the highest value. Our results indicate that risk assessment can be contribute to screen the pollution safe rice cultivars in paddy fields affected by the mining activity.

Purpose : Iron deficiency is still the most common nutrient deficient disorder despite the improvement in general health and nutrition. This study is designed to evaluate the dietary history of infants and young children with iron deficiency anemia(IDA) and the effects of nutritional counseling. Methods : This study was conducted on 120 children from 6 to 36 months of age with IDA. Their parents completed a questionnaire and took counsel for nutrition. IDA was defined as Hb <11.0 g/dL, ferritin <10 ng.mL or transferrin saturation <15%, or Hb increase >1 g/dL after iron preparation. The questionnaire consisted of their feeding patterns, weaning time and kinds of food. Results : In the 120 infants and young children aged from 6 to 36 months, the parents of 82 cases was counseled about nutrition. Fifty six infants among 82 cases have started weaning and the main foods of weaning were rice and/or rice gruel. Nutritional problems in weaning were that some children over one year of age were using a bottle, and parents restricted weaning food at will because of allergic disease or chronic disease. Most parents were satisfied with the nutritional counseling given from a clinical dietitian and showed good compliance. Conclusion : Many infants and young children with IDA were provided with non iron-fortified foods and made an inadequate wean. Most parents were satisfied with the nutritional counseling and showed good compliance. The need of dietary counseling was required for prevention and treatment of iron deficiency anemia because of inadequate weaning.
