This study was conducted on 175 child-care teachers, who participated in in-service education, to research the methods to improve child-care teacher's nutrition management capability for infants and children. Investigated results of child-care teachers' nutrition knowledge, dietary attitude status, and needs on nutrition education in child-care centers are as follows: The score of child-care teachers' nutrition knowledge was 10.83 points out of 15, which is about 72%. Total score increased as teachers' age but not significantly different from their career duration, since teachers who have a child-care career less than 5 years acquired 10.91 points, which is higher than 10.64 points of teachers having more than 5 years of child-care career. Teachers' average recognition to the nutrition knowledge was 90.6%, increased significantly by the older they are, and decreased according to the accumulation of their career. The average accuracy of the nutrition knowledge was 79.7%, increased in proportion to the teachers' age. The marks of child-care teachers' dietary attitude were 41.3 points (possible score range 5-50) and 83%, older teachers tended to have more desirable dietary attitude. As indicated by the increment of child-care career, the score of emotional attitude tended to be increased but which of cognitive and behavioral attitude showed a declining tendency. Nutrition information which child-care teachers were mainly interested in were correct selection of food (58.1%), obesity and weight management (52.7%), and nutrient content of food (44.9%). Nutrition education contents which child-care teachers needed were 'nutritious food and menu for child' (72.2%), 'health management of child' (69.2%) and meal management of child (40.2%). Nutrition education methods, which child-care teachers considered as of desirable ones, were cooking class of small scale (31.8%), visiting class at child-care center (26.5%). In consequence, the nutrition knowledge and dietary attitude of child-care teachers were not good and showed different issues by age and career duration. Therefore, it is requisite to intensify nutrition management courses in child-care teachers' qualification and in-service education courses which has actual necessity and suitability based on teachers' age, career, and the type of child-care center, and to disseminate these through public health centers and child-care & education information centers to pursue the efficient balance of nutrition education programs.

This study was carried out to investigate the effects of diverse dietary Ca levels and to determine whether bone mineral metabolism is influenced by the arnount of dietary Ca when given a choice of diets containing various levels of Ca. Forty Hy-line brown laying hens housed in separate cages were fed self-selected Ca diets. Birds were allowed a 7-day adaptation period followed by an 8-day collection period. Feed and water were available for ad libitum consumption. Eggs and excreta were collected at 6-h intervals during the day for mineral analysis. The Ca contents in excreta and retained Ca in the body on egg forming day were proportional to the amount of daily Ca intake. The retained Ca in the body were 0.97 g in control and 1.24~1.74 g in self-selected groups, respectively. Daily Ca contents (%) in tibial cortex were not consistent with feeding time intervals. The Ca content in tibial medulla in control group was lower than those of self-selected feeding groups(P<.05). The medullary Ca content in all treatment groups increased from 10:00 to 16:00 in a day. Ca content in plasma was low between 10:00 and 16:00 and was high between 22:00 and 04:00 in the following day.

The primary objective of this study was to learn the effect of various sugar particle size and level on cookie spread, The effect of sugar particle size and level on sugarsnap cookie spread was studied. Three different particle sized sugars; powered sugar, granulated sugar and sanding sugar, were used for the cookie test baking with five different sugar levels; 30, 45, 60, 75 and 90% based on the weight of flour. In mixing process, 5 minutes of creaming time was used for cream making and then the specific gravity of cream was measured on the basis of each different sugar particle size and level. In the result, the specific gravity of cream was influenced by sugar particle size and sugar level. However, the specific gravity of cream had no influence on cookie dough specific gravity. Cookie spread was influenced by sugar particle size and sugar level. Greater cookie spread was obtained by decreasing sugar particle size and increasing sugar level resulted in increased spread. Therefore, selection of suitable sugar particle size and its use level can be factors in controlling spread and imparting desired packaging characteristics.

For the purpose of implementing health and nutrition education for college women, we investigated changes in height, weight, and daily living schedule, as well as the relationship between energy intake and expenditure, and food and nutrients intake levels for the six years from 1977 to 1982. A special form of questionaires was prepared and distributed to well-trained subjects (total 213) in order to find out their general characteristics, daily living schedule and dietary intakes. The recovery of questionaires distributed to each subject was 90%. Then the quality of their living, energy balance, nutrient intake and food intake were evaluated and the F-test was used to test the statistical significances. It was found that : 1) The range of weights and heights of subjects were between 48-50 kg, 157-161cm respectively over the 6 year period. 2) In daily living schedule, that is, the average physiological activity time including sleeping ranged from 760 to 801 minutes. Free time decreased gradually, from 318 minutes per day in 1977 to 275 minutes in 1982. Average time for study and for house work was 196-280 minutes and 68 - 157 minutes respectively for 6 years, and study time was significantly varied in each year. 3) The energy intake of the subjects averaged 1762 Kcal, whereas the expended energy was 1892 Kcal. In the energy balance determined by the relationship between energy intake and expendituye, the ratio of subjects who maintained a negative energy balance gradually increased from 53% (1977) to 64%(1982). 4) The average nutrient intake was higher than the recommended dietary allowance except for calorie (1997 - 1982), calcium (1979) and iron (1979, 1980). The total calorie intake was composed of 59-63% carbohydrate, 19 - 24% fat and 15 - 18% protein Of the total protein intake the percentage of animal was 47 -51% for six years, showing acceptable nutritional status. 5) The average total food intake of the subjects increased from 1,080 g (1977) to 1,184g (1982), but this was not a significant difference. Cereal composed the highest proportion among the total food intakes, and rice intake was 58-78% of cereals. Cereal was followed in decreasing order by vegetables, dairy products, fruits, meat and fish products. The option available for the selection of cooking methods as well as the selection of food item was limited, so there were few changes over time.

The purpose of this study was to explore dietary attitude among middle school students by sex. The subjects were collected from 211 boy students and 198 girl students in the city of Kunsan, Jeonbuk province. The mean age of the subjects was 13.7 years old. The average score of food habit was 4.61 $\pm$ 1.92. The average score of food habit of boy students was higher than the score of girl students. The correlations between the score of food habit and father's education level. family income, and nutritional supplements were positive. The correlation between the scores of the nutrition knowledge and father's education level was also positive. On the other hand the mother's occupation did not have any influence on the scores of food habits and the scores of the nutrition knowledge. As a staple food, cooked rice was preferred on boy and girl students at breakfast(82.7%) and supper(94.3%). The preference of snacks was fruit and fruit juice. The reason of skipping breakfast was the lack of time and no appetite, and skipping lunch was due to no appetite. Lastly the main reason of skipping supper was playing computer on boys. on the other hand no appetite and weight control on girls. In order to improve the nutritional status of the middle school students, they must establish good food habits by eating three regular meals per day and balancing their diet. Also they should be notified that severe weight control is very harmful for health. This study indicate that nutrition education and correct information for body image. balanced diet. regularity of meals and food selection are required for middle school students at both school and home.

Korean food is being recognized for its excellence. This paper attempts to provide material for the popularization of Korean cuisine with respect to foreign nationals living in Korea who are vegetarian by studying their Korean cuisine knowledge and preferences. The results of an Importance-Performance Analysis showed that though the importance values of traditional spice use such as garlic and the consideration of ingredient price were high, their performance values were low. Thus, these were areas identified as needing major improvement. Repeated measured data analysis was performed to determine variations in the perception of major factors for the development of Korean cuisine. The results indicated that simplification of seasoning was the most important factor followed by diversification of food ingredients, resale of vegetables in small quantities, ease of obtaining Korean cuisine recipes, and popularization of herbal and temple food, in that order. The least important factor in developing Korean cuisine was determined to be the reduction in levels of salt. Conjoint analysis was performed on the choices affection the selection of Korean cuisine, and price was found to be the most important factor. It was also determined that the effectiveness in the combination of fusion style, health oriented, concurrently served, medium to low price Korean cuisine was highest in preference. The next highest preferred combination was traditional style, health oriented, concurrently served, medium to low price Korean cuisine. The most significant factor to keep in mind in developing Korean dishes for foreign vegetarians was determined to be price. Furthermore, it was important to not simply reduce caloric intake but to use healthy ingredients and cooking methods.

Nutrient intake data collected by both dietary methods of the 24 hour recall method and the food frequency method from 538 middle school students were analysed to investigate any measurement errors occuring while using these methods. Measurement errors were observed both in terms of differences of average intake and consistancy from the two sources of data used. Wilcoxon signed ranks test was used to test the differences between the two average intakes and Speraman's rank order correlation coefficient was used to test consistancy. As a result, average intake value estimated from the food frequency method tended to be higher than that from the 24 hour recall method. The degree of overestimation varies from one nutrient to another. For instance, carotene showed not only the most significant differences in average intake but also showed the most incoisistancies between the two sets of data. This may imply the validity of nutrient intake as derived from different dietary survey methods varied from one nutrient to another, therefore the selection of dietary survey methods has to be made more cautiously in the case of certainnutrients.
