This study investigated the educational status, students' recognition, educational needs and degree of difficulty on the food and nutrition section of Technology Home economics subject in middle schools. It was carried out through questionnaires. The subjects were 503(boys; 246, girls; 257) middle school students in 3rd grade in the Daejeon area. The results were as follows. The students' preference for food and nutrition section was 58.5% of boys and 72.0% of girls. On the educational status of this section, The highest cooking frequency was once a year(52.3%), but 12.9% of students had never done cooking practice. Generally, practice education was not enough in subjected schools. The education of food and nutrition section was mainly conducted by lecture. For the behavioral change of students after learning this section, 'I can cook some simple foods' was the most(36.8%) than the other. The contents of high educational needs in this section were 'cooking foods' and ‘basic cooking methods'. A average degree of difficulty in this section was 2.89 points of the likert scale(1~5 point), particularly, 'change of food components by cooking' was the highest at 3.17 points of likert scale(1~5 point) in this degree. In relation to demographic background, the difficult degrees of this section were significantly higher than the other, when their parent's education was under middle school and their fathers' had no occupation. It suggests an increase in cooking frequency, complementing contents needed in life and using various audio-visual education aids are necessary for the education of food and nutrition section.

Purpose: To compare between sodium acetate (SA) and sodium chloride (SC) in parenteral nutrition (PN) with associated metabolic acidosis and neonatal morbidities in preterm infants. Methods: Preterm infants below 33 weeks gestational age, and with a birth weight under 1,301 g were enrolled and further stratified into two groups: i) <1,000 g, or ii) ≥1,000 g in birth weight. The subjects were randomized to receive PN containing SA or SC within the first day of life. The results of routine blood investigations for the first 6 days of PN were collated, and the neonatal outcomes were recorded upon discharge or demise. Results: Fifty-two infants entered the study, with 26 in each group: 29 infants had extremely low birth weight (ELBW). There were no significant differences in birth weight, gestation, sex, exposure to chorioamnionitis and antenatal steroids, surfactant doses and duration of mechanical ventilation between groups. The SA group had significantly higher mean pH and base excess (BE) from days 4 to 6 than the SC (mean pH, 7.36 vs. 7.34; mean BE -1.6 vs. -3.5 [p<0.01]), with a two-fold increase in the mean BE among ELBW infants. Significantly fewer on SA required additional bicarbonate (n=4 vs. 13, p=0.01). The rate of bronchopulmonary dysplasia (BPD) was approximately four-fold lower in SA than SC (n=3 vs. 11, p<0.01). No significant differences were observed in necrotizing enterocolitis, patent ductus arteriosus, retinopathy of prematurity, cholestatic jaundice, and mortality between groups. Conclusion: The use of SA in PN was associated with reduced metabolic acidosis and fewer BPD.

This study was designed to investigate nutrition intakes and its relation to the obesity and the prevalence of anemia in 252 children(136 boys, 116 girls) aged $2{\sim}6$ years. The hematological parameters, daily nutrient intakes and height and weight were measured. Calorie intakes of 2 and 3year-old-children were over their RDA while those of 4-6 years were below the RDA. Intakes of protein, P, and vit B complex were far over the RDA in all ages of children. Fe and vit A intakes were insufficient in all ages except 3 years while Ca intakes were insufficient in all ages except 2 and 3 years. About 18.2% of the children were evaluated as obese. However, very few children were anemic by hematologic parameters. The mean Hb concentrations were 12.2mg/dl in boys and also in girls. The mean Hct was 36.2% in boys, 35.8% in girls. Serum Fe concentration was 100.1mg/dl in boys, 101.1mg/dl in girls. RBC count was significantly higher in boys while MCH was significantly higher in girls. Intakes of protein, P, Fe, vit $B_1$, niacin, vit C were significantly higher in obese group compared to under weight group. There were significant positive correlations between protein intake and Hb, Hct, MCH, and MCHC. The correlation between Fe intake and Hb or Hct was not significant. In conclusion, it seems that the nutritional status of the most children was in very good condition. However, they needed to take more foods supplying Fe, Ca, and vit A.

The objective of this study is to investigate various jobs and foodservice environments, as well as work performances of school foodservice dietitians and nutrition teachers in accordance to the years of service in Daejeon and Chungnam provinces. A survey was conducted among school foodservice dietitians and nutrition teachers; a total of 415 from selected elementary, middle and high schools in the areas. In this study, we surveyed the participants and analyzed the current state of general characteristics, status of their job environments and foodservice environments by frequency, and the averages and differences in work performance with regard to 12 work parts and 57 works using one-way ANOVA and Duncan's multiple range test according to the years of service. Six parts among 12 work parts were significantly different in work performance according to the years of service. The 6 work parts were menu (nutrition) management, utensil recovery and management, sanitation management, foodservice administration & evaluation, dietary habit guide, and other works. The 11-15 years group ranked as the top on the total score and means of work performance. While the 16-years or more group, 6-10 years group, and under 5 years group followed consecutively. Correlation analysis between job or foodservice environments and work performances showed that work performances of school dietitians were mostly influenced by employment status, education level, and annual salary among the variables of job or foodservice environments. Other works, dietary habit guides and menu management were mostly influenced by variables of job and foodservice environments.

In order to investigate food purchase frequency of elementary school children and its related ecological factors, 431 4th, 5th and 6th grade elementary school children and their mothers, living in Seoul and Daejon, small city and rural area of Chungnam Province, were participated in this study. The subjects and their parents were surveyed by a self-recording questionnaire about food purchase frequency and some ecological factors. Average height and weight of the subjects by gender and grade were similar to or a little bit more than the 1998 Korean Growth Standard. According to relative body weight, 30.6% and 10.8% of the subjects belonged to under-weight and obesity categories, respectively. Of the subjects, 46.9% used PC telecommunication or internet, 53.8% of them used it for less than an hour per day, and 46.4% watched TV for 2 to 4 hours a day. About 42% of the subjects spent 500 Won or less daily to buy snacks. A half of the subjects took snacks once a day because of hunger. Mothers' nutrition knowledge score was averagely 8.16 out of 13 full score and the average attitude score was 43.22 out of 50 full score. Foods purchased more than once a week were milk and yoghurt, cookies, ice-cream, ramyun, and gum in order. Family income, parents' education level, mothers' nutrition knowledge and food attitude score, students' snacking frequency and TV watching time showed significant correlations with purchase frequencies of some individual food items. In conclusion, the elementary school children considered taste most important rather than nutrition in buying snacks and most frequently bought carbohydrate foods and concentrated sugars except milk. Ecological factors such as mothers' nutritional knowledge and food attitude, TV watching time and snacking frequency had influenced the children's food purchase frequency. Accordingly, it is necessary to educate both children and their mothers about good food purchase and the importance of snacking.

In this study, we investigated the inhibitory effects of Baechu kimchi added Ecklonia cava on the activities of ${\alpha}$-glucosidase and ${\alpha}$-amylase and its alleviating effect on the postprandial hyperglycemia in STZ-induced diabetic mice. Baechu kimchi added Ecklonia cava (BKE, 15%) was fermented at $5^{\circ}C$ for 28 days. Optimum ripened BKE was used in this study as it showedthe strongest inhibitory activities on ${\alpha}$-glucosidase and ${\alpha}$-amylaseby fermentation time among the BKEs in our previous study. The BKE was extracted with 80% methanol and the extract solution was concentrated, and then used in this study. The BKE extract showed higher inhibitory activities than Baechu kimchi extract against ${\alpha}$-glucosidase and ${\alpha}$-amylase. The $IC_{50}$ values of the BKE extract against ${\alpha}$-glucosidase and ${\alpha}$-amylase were 0.58 and 0.35 mg/mL, respectively; BKE exhibited a lower ${\alpha}$-glucosidase inhibitory activity but a higher ${\alpha}$-amylase inhibitory activity than those of acarbose. The BKE extract alleviated postprandial hyperglycemia caused by starch loading in normal and streptozotocin- induced diabetic mice. Furthermore, the BKE extract significantly lowered the incremental area under the curve in both normal and diabetic mice (P<0.05). These results indicated that the BKE extract may delay carbohydrate digestion and thus glucose absorption.

This study is to research the use and the demand of the elderly generation that pursue economic ability and active lifestyle. The composition of the meals were "homemade meals" 65.3%, "homemade & convenience meals" 26.7% overall. For the "never miss a meal" category, 70-74 years old was 48.3%, over 80 years old was 60.0%. The elderly under 70 years old showed a high frequency in the use of alternative meals (p < 0.05) and the elderly with higher education used the alternative meals more frequently (p < 0.01). The rice-cakes, bread, tuna cans, Korean side-dishes, beverages, meat, cup-noodles and seafood as alternative meals are in the order of most frequency. Also, 96.0%, 59.0% and 46.5% of the elderly had experience in using "Ready to eat (RTE)", "Ready to heat (RTH)" and "Ready to cook (RTC)". The oldest group surveyed, the elderly at the age of 80 years old and above showed lower preference for "completely cooked state" but showed highest results in the "half-cooked state". This shows the difference between people's perception and the behavior that showed high frequency of 96.0% in the experience with "RTE". This can be inferred that the elderly needs the development of convenience food that is moderately packaged according to the newer lifestyle where the elderly live independent from their children. Moreover, there is a higher demand in the healthy convenience food, which means that there is a need for development in the quality of the convenience food that will allow more faith in convenience food by the elderly.

Objectives: The study was performed to examine the dietary behaviors and life stress of middle school students in the Gyeonggi area. Methods: A total of 580 middle school students (295 males, 285 females) in the Gyeonggi area participated in the study between July and August in 2011. The study was a questionnaire-based survey that included dietary habits, dietary behaviors, and life stress. Results: For dietary habits, the score for drinking milk was higher in male students than in female students, whereas the score for eating fruits was higher in female students compared to male students. There were significant differences in foods eaten and preferred under stress between male and female students. Male students showed significantly less changes in the number of meals, amount of meal intake, number of snacks, snack intake, frequency of overeating, and appetite during stress than female students. Life stress score of students largely came from academic factors, and female students showed higher stress levels in personal and surrounding environment factors than male students. Life stress score was significantly lower in students with high and moderate levels of dietary habits than in students with a low level of dietary habits. Total score for dietary habits and scores for eating adequate amounts of foods for each meal, considering a combination of food groups at each meal and eating green and orange vegetables, were significantly negatively correlated with life stress score. Life stress score was significantly negatively correlated with meal regularity and positively with the level of overeating. Conclusions: This study may provide basic information on dietary habits and life stress according to gender and the relationship between dietary behaviors and life stress of middle school students, and it suggests gender-based nutrition education programs to solve undesirable dietary habits and dietary behaviors in students with higher stress.

I. Subject of the Study A study on the nutritive composition and utilization of wheat or barley for the improvement in our national dietary life. II. Purpose and Importance of the Stu요 1. Korea has long depended on rice for its staple food, but a sharp increase in population in recent years has brought about the shortage of rice, which makes it inevitable to import a great quantity of foreign rice. It is considered therefore that the development and utilization of other cereals than rice is a serious and pressing problem facing Korea. 2. Wheat and barley are the second largest products next to rice in Korea and it is desired that the composition of several kinds of wheat and barley be analysed and their nutrition which rates with differing degrees of hulling process be specified. 3. In this study, the experiment has been carried out in the following order: first, seven species were selected among various kinds of wheat and barley produced in Korea to analyze their respective composition, and to determine the most ideal degree of hulling process on 5 kinds among the 7 kinds: second, ratio of mixing rice with wheat or barley is increase the nutrition value and to seek selfsufficiency in staple food supply: third, economical and reasonable way of improving the nutrition value in the national dietary life is suggested by developing a simple and easy recipe which is also to the taste of the population. III. Contents and Scope of the Study 1. Objectives of the study The objectives will come under five items.

This study aimed to investigate the relationship between meal regularity (i.e. breakfast intake and meal-times), and the risk of metabolic syndrome (MetS) among generally healthy Korean single-person household adults (≤60 years, n=594) based on the Seventh Korean National Health Examination and Nutrition Survey (KNHANES) (2016~2018). Among men (n=325), the breakfast intake frequency was not significantly associated with the pervalence of MetS. However, men consuming a regular meal at least once a day showed a lower prevalence of MetS compared to those whose meals were irregular. These patterns remained after adjusting for age, smoking and drinking habits, individual income, education level, exercise, and total calorie intake. An association between meal regularity and MetS risk was observed in post-menopausal women (n=84), but not in pre-menopausal women (n=185). More specifically post-menopausal women with irregular breakfast eating habits or eating no breakfast at all showed a significantly higher risk of MetS than those eating breakfast regularly after the adjustment. The analysis revealed an odds ratio (OR) of 8.46, confidence intervals (CIs): 1.149~62.199, P<0.05 in irregular breakfast eaters, and an OR of 13.377, CIs: 1.665~107.511, P<0.05, in those who ate no breakfast. Furthermore, post-menopausal women who had irregular meals daily showed a higher risk of MetS than those consuming one or more regular meals/day after the adjustment (OR: 16.888, CIs: 1.258~226.655, P<0.05). In conclusion, the results from this study may be used for formulating optimal dietary guidelines for the prevention and the management of MetS in adults in single-person households.
