Maternal stress was very common symptom that every pregnant women could have experienced during pregnant period. We found that the causative factors of stress for subjects were physical change(50.8%), family relationship(13.6%), change of body image(7.4%), concern baby(6.8%), economic difficulties(6.4%), depress(4.3%), morning sickness(3%), and miscellaneous(3.5%). According to our study, maternal stress during the first trimester negatively correlated with food and nutrients intake of pregnant women and gave low weight gain during pregnancy and low birth weight of infants. It also significantly correlated with monthly income(p〈0.001) and monthly food cost(p〈0.001) during pregnant period. Mean intake of Calcium and Iron were 47~60% of RDA and 35~48 of RDA, respectively. With the Iron supplement the total intake of Iron exceeded 100% of RDA. We also found majority of food items, except seaweeds, fruits and vegetables, were negatively correlated with maternal stress during three trimesters. Additional support system projected by professionals in health-care field could mediate maternal stress and lead to healthy pregnancy outcome.

The purpose of this study was to investigate to the effect of regular exercise on nutrients intakes and energy balance related to food habit and nutrient knowledge of college women. This study was conducted from May to June in 2000. One hundred and forty female students made their three day dietary records by 24-hr recall method and one day activity record. The questionaires were designed to fine out food habit and nutrition knowledge status. The height, weight and blood pressure were measured and also body fat mass and lean body mass measurements were performed. The results obtained are summerized as follows Average height and weight of E(exercise) group were found to be increased than those of NE(non -exercise) group. The percent of body fat and body fat mass(㎏) in E group were slightly lower than those of NE group. Calorie intake of NE group was 1, 664㎉ per day, This was composed of carbohydrate 60%㎉, protein 14%㎉ and fat 24%㎉. Calorie, calcium, iron, vitamin A, vitamin B_2 and niacin intakes of NE group were lower than those of RDA and calorie intake of E group was 2, 313㎉ per day. This was composed of carbohydrate 54%, protein 13% and fat 31%. Other nutrients such as iron, vitamin A, niacin and vitamin C were lower than those of RDA. Daily energy expenditure and physical activity of E group were 2, 397.6±49.2㎉, 1, 035.7±36.5㎉, respectively and it was higher than those of NE group.

Since 1982, female agricultural workers are populous than male in Korea. Previous study was suggested that female workers are more sensitive to the agricultural medicine poisoning than male. This study was conducted with the aim of evaluating the impact on plasma components and nutrient intakes in female agricultural workers by the use of pesticides. Data were obtained from 44 females residing in Wonjoo, Kangwon-do area. Analysis for the general characteristics, nutrient intakes, and plasma components of the subjects were performed by physical examination, 24-hour recall method and venous blood sampling. They were divided into 3 groups according to the degree of the pesticide use: 8 in none(Non-expose group), 14 in low(〈4/yr)(Low-expose group), and 22 in high(≥4/yr)(High-expose group). The results are summarized as follows. Serum glucose, SGOT, SGPT, triglyceride, HDL-cholesterol did not correlated with pesticide use and were not different among the groups. But serum total cholesterol was higher in pesticide use group. With increasing the number of pesticide use times, leukocyte count was tended to increased. Eighty two percent of the subjects were hemoglobin less than or equal to 12g/dl. Hematocrit, MCV, MCH, MCHC, serum Fe, Serum ferritin belonged to normal range and did not correlated with pesticide use. Intake of energy, Fe, vitamin B2 were lower than RDA. Fe, K, and vitamin A intake were higher in don't use group than the other groups. There are not many differences according to using the pesticide in anthropometric measurements, nutrient intakes, and blood components, except for serum total cholesterol level and some nutrients intake. But these results suggest the need the systemic researches about the effects the pesticide using on nutritional status in Korean agricultural workers.

A survey was carried out to investigate relation between life stress and nutrient intake status in female university students. It was represented that increasing trends of food intake under the stress condition and preference taste was sweet and hot in female students. The female students thought that food intake for coping with stress was produced negative results and they perceived the relation between stress and their health problem. There was a positive correlation between stress level and the change of food intake in female students statistically(p〈0.01). They had higher stress in future prospect, academic problem, friend relationship, personality and family relationship. The average calorie intake of female university students was 1553.06kcal(77.65% of RDA). The intake of protein, calcium and iron were quite less than the RDA, whereas the intake of phosphate, vitamin A, B2, C, niacin were more than the RDA. In changes of nutrient intake under the stress conditions, the higher stress group had decreased intake of calcium, iron, vitamin B1, B2, C than the lower stress group(p〈0.05).

This study was conducted to assess dietary intake and quality obtained by 24-hour recall method between Korean-Chinese in Yanbian, China(Korean-Chinese) and Koreans in Kuri, Korea(Koreans). The subjects consisted of 730 Korean-Chinese and 696 Koreans. Mean daily energy intake of Korean-Chinese was 1,788kcal and that of Korean was 1,844kcal. Proportions of energy intake from carbohydrate, fat, and protein were 62.6: 16.9: 14.2 for Korean-Chinese and 65.4: 16.3: 14.4 for Koreans. Nutrient intake levels of Koreans were higher than those of Korean-chinese in most nutrients. Calcium and vitamin B2 intakes as percent of Korean RDA were less than 60% in Korean-Chinese. Koreans consumed calcium and vitamin A in the level less than 80% of Korean RDA. Iron intake level of Korean females was less than 75% of Korean RDA. Korean-Chinese consumed 90.4% of food from plant origin, and Koreans consumed 82.5% of food from plant origin. Mean dietary diversity score(DDS) of Korean-Chinese, 3.00±0.39, was significantly lower than that of Koreans, 3.73±0.76(p<0.05). Mean dietary variety score(DVS) of Korean-Chinese, 13.6, was significantly lower than that of Koreans, 20.1(p〈0.001). According to these results, some adults in the both Korean-Chinese and Koreans did not consume enough nutrients, especially calcium and vitamin B2 intake for Korean-Chinese and calcium and vitamin A intake for Koreans. Dietary qualities of Korean-Chinese subjects and Korean females were not adequate. In the future, further research to promote dietary quality of Koreans including Korean-Chinese must consider the results of this study.

This study was conducted to estimate the prevalence of ametropias such as myopia and hyperopia from the community based population study. Another purpose of this study was to determine the association between ametropia and nutrient intake. The study subjects was 492 residents over 20 years of age residing in Kuri City. Ametropia was tested based on refrector error using auto referactor. Nutrient intake was estimated from the dietary survey using 24 hour recall method. As a result of data analysis, the prevalence of myopia was 57% and that of hyperopia was 11%. Such a high rate of ametropia prevalence may suggest the increasing risk of eye health in a Korean society. Nutrient intake of myopia group was 5∼15% higher than that of normal group in most of the nutrients. Whereas intake of most nutrient except calcium, retinal, fiber for the hyperopia group was lower than that of normal group. The result may suggest that inbalance of nutrient intake has been related with ametropia.

A survey was carried out to investigate relation between stress and nutrient intake in adults. There was a positive correlation between stress and food intake in adults statistically. It seems that women was significantly influenced by physical, psychological and nuerosensational stress than men(p〈0.05). The average calorie intake of men was 1721.25Kcal(68.85% of RDA), the women was 1568.79kcal(78.44% of RDA). Intake of protein, calcuim, Vit B1, Vit B2, Niacin were quite less than the RDA in men, wherase intake of calcuim, iron, Vit B1 were quite less than the RDA in women. In changes of nutrient intake by stress, men was increased as higher stress amount, but women was decreased as higher stress amount(p〈0.05). It was lower level of nutrient intake in the below 60 scores of food attitude group that was needed improve of food intake and counseling of professional nutritionist.

This nutritional survey was conducted in February 25, 1999, in order to investigate the nutritional knowledge, dietary attitudes and nutrient intakes of dietitians living in Kangwon area. Subjects consisted of 250 dietitians, with 184 in school food service, 14 in hospital food service and 52 in institution food service. Data were analyzed for frequencies, means, t-test, 2-test, ANOVA and Pearson correlation using SPSS PC Package. The results obtained are summarized as follows: The average nutritional knowledge score was 10.15 out of possible 15 points, and dietary attitude score was 67.93 out of 100 points. The correlation between nutritional knowledge score and dietary attitude score was lowly(γ=-0.25). Nutrients consumed below the Korean RDA were energy (78.77%), Ca(90.5%), Fe(83.70%) and nutrients consumed above the Korean RDA were protein(110.83%), P(140.21%), vit.A(163.94%), vit.B2(126.37%), niacin(121.12%) and vit C(231.86%). Carbohydrate, protein and fat ratio on energy composition was 63%:17%:20%. The nutrient density among 3 groups of dietitian was not significantly different.

According to economical status, under-nutrition and over-nutrition coexist in preschool children in Korea. Subjects consumed more than RDA in most nutrients, and children in of the upper income class tended to have more nutrients than those of the low income class. Especially in case of energy, protein, fat, vitamin B2, and P there were significant differences among the different classes. The mean calorie compositions of carbohydrates, protein and fat were 57~59: 16~17: 26~27 and fat calorie percentage was higher than quantity recommended for Korean adults. Energy, protein, Fe, vitamin A, B1 and C intakes were taken mostly from plant food sources. In the upper income class group, intakes of protein and vitamin B2 from animal food sources were higher than in any other income classes. Intakes of iron, vitamin A, B1 and C were largely provided by plant food group. Especially 44-45% of vitamin A were taken from vegetable and fruits group, which indicated that about 50% of vitamin A intake was the form of β-carotene. Also compared with other groups, in the upper income class group, the intakes of energy, protein, Ca, p, vitamin B1 and vitamin B2 from cereal and potatoes were significantly lower, and those of Ca and P from milks and meats, fishes & eggs were significantly higher(p〈0.05). The mean fat intake in all subjects was 38~43g/day. Regardless of income class, oleic acid(6.6~8.4g) and linoleic acid(6.7~8.1g) were the most abundant fatty acids contained in the diet. The upper class group consumed significantly more total saturated fatty acids and total monounsaturated fatty acids(p〈0.05). In polyunsaturated fatty acids, there were no differences between 3 different income classes, but intakes of total Ω6 fatty acids in the upper class tended to be higher and those of total o3 fatty acids in low class tended to be higher. Therefore, Ω6/Ω3 tended to be higher in the upper class group. Regardless of income classes, P/M/S and Ω6/Ω3 ratios in all subjects were 0.9~l.3/1.0~1.1/1.0 and 5.2~7.4/1.0, respectively and were in a desirable range. Cholesterol intake of subject was 184-218 mg/day, which was comparable to the value of Korean adult intake.

This study was designed to investigate food consumption patterns and nutrient intakes of college students, divided into subgroups of normal weight men (no.=140), normal weight women (no.=101), and underweight women (no.=155) by body mass index. Frequency of food eaten, nutrient intakes from each meal, percentages of RDAs, and nutrient densities were analyzed using 24-hour recall records. It was very interesting in these results as follows. Normal weight men ate on the whole more frequently than other groups. Underweight women had higher intakes of nutrient than did normal weight women. However normal weight women consumed food of greater nutrient density than did other college students. Consequently, it is desirable to suggest nutrient density of food than learn RDAs for adequate diet in nutritional education programs.

The dietary intake of nutritional elements by Koreans as determined by the Ministry of Health and Welfare's National Nutrition Survey have been reported for 1969~1993. But these data were based on not dish but food. Therefore, the purpose of this study was to compare dish sources of energy and macronutrients (carbohydrate, fat, protein) in the diets of three area (large city, small city and rural). Dish sources were evaluated from two-day record obtained in the secondary analysis of the 1993 Korean National Nutrition Survey. The result, large city and small city had higher fat and protein intake than did rural. Otherwise, carbohydrate intake among rural was higher than those among large and small city (p〈0.05). The primary dish source of energy and macronutrients was cooked rice for all area. The percentage of cooked rice in daily carbohydrate intake was 52.64% for nationwide, 48.40% for large city, 50.52% for small city, 61.79% for rural. The cumulative percent of top 10 dish sources to carbohydrate for large city, small city, rural were 78.02%, 81.16%, 85.69%, respectively. These was higher than cumulative percent of other macronutrients. The milk as good protein source ranked 3 for large city, 6 for small city, 22 for rural. The major dish sources to fat were cooked rice and pork that prepared by various cooking way. These results show that the major dish sources of energy and macronutrients were cooked rice based of Korea traditional consumption pattern. The most of nutrient intake consumed some dishes for all area. The dish consumption pattern was generally similar between large and small city. But rural was different from other area. Threfore, nutrition educations and interventions should be targeted to each area and should be attended with studies that comparision of dish sources to nutritional elements by specific age-sex groups.

Rye(Secale cereale L.) shows lower dry matter yield and nutrient content when it was harvested before wintering. This study was conducted to investigate how effect forage rape(Brassicu napus Subsp oleifera), which carries early maturity and can be harvest

This experiment was carried out to investigate to adaptability of forage rape(Brassica napus oleifera) and the determine its proper sowing time for a second cropping on the fallow field after sweet corn yield in the Hongchon area The forage rape, Ramon wa

This study was carried on the analysis of food and nutrient intake for elementary school foodservices in Seoul. The survey was conducted through the 200 menus submitted by the 5 elementary schools in Seoul. Energy and all nutrient intakes exceeded the Recommended Daily Allowances of Koreans. Carbohydrate provided 56.32% of total energy intake; protein accounted for 16.06%; fat provided 27.62%. Total intake of food was 549 g on the average, which consisted of 90.04 g cereals, 130.17 g vegetables, 31.56 g meats, 21.63 g fishes and 200.00 g milks. The basic menu patterns were Rice+Soup (or Stew)+Kimchi, and 2 other side dishes including milk. These data underscore the necessity of developing the 'Standard Menu' for elementary school foodservices.

This research was designed to see the relationship among nutrient intake, food intake frequency and psychosocial stress in ordinary life. The subjects were 190 males and 263 females of university students in urban areas. There were significant correlations between nutrient intake and stress value, and between food intake frequency and stress value. In male, the more they consumed energy, protein and carbohydrate, the higher they had stress in several categories. But in female the results were reversed. Their stress values were lower when they have consumed protein source food frequently. And in general, stress values of female were higher than those of male. From these results, we conclude that nutrient intake tends to be decresed with increase stress in less stressful condition, but to be increased in more stressful condition.

This experiment was conducted to know what does the cutting date have an effect on the chemical composition and nutritive yield of Miscanthus sinensis, in order to determine the optimum cutting date of the plant when it is utilized as roughage. Miscanthus
