An ecological survey of food and nutrition was conducted in April and May, among 278 children, 6 to 12 years old, of the Youido elementary school, which offers no school lunch program, and is situated in Youido delta of Han River side of Seoul, known as the location of one of the socioeconomically high groups; Eighteen percent and 18.3% of subjects were proven to be overweight and obese, respectively. With regard to frequency of skipping breakfast, 28.4% of the subjects skipped breakfast often and 2.5% of subjects skipped breakfast every morning. Obese children showed good appetite and the time consumed for eating was shorter than those of normal or overweight children. Most serious anxiety among the mothers for those children was food habit of `eating rapidly' and `overeating'. Another striking observation was that 14.4% of the subjects ate only one side-dish with boiled rice, and such a pattern was more often found in the normal or slim group. Most of the subjects had their snacks after being back in home from school. Thirty-one percent of the children had snacks when they felt hungry, 69% had snacks for various reasons such as `habitually', `for unwinding', and `mother gives me snacks'. Thirty-eight percent of the boys and 19% of the girls had physical exercise everyday and overweight and obese children got exercise more frequently. But the time consumed for exercise was much more shorter than that of normal subjects. Most of the children liked fruits, meats, and biscuit, in contrast, lowest preferency was for vegetables, fermented fish products, and boiled rice mixed with other grains. Obese children experienced more kinds of food than normal or slim group. The study found that habits of overeating due to good appetite and eating rapidly were recognized as one of dominant reasons causing obesity among children. On the other hand, serious dietary problem of children of normal or slim group was eating less variety of food. Active nutrition education for both children and mothers will be recommended with joint participation of teachers.

These studies were conducted to: a) investigate work patterns and productivity indices, b) rate performance levels of employees and c) determine the suggested levels of personnel and labor hours for the effective labor control in school foodservice. Eighteen elementary school foodservices in Seoul were selected in order to analyze work patterns by the work sampling methodology. Allowance time and performance rating by VTR observation was done to determine the standardized labor hours. The results were as follows. The average percentage of each work function of the total work functions such as direct work function, indirect work function and delay were 65.57%, 8.12%, 26.31% respectively. The productivity index is 0.92 min/meal. The average working and delay hours per week of the foodservice director, foodservice employees and supply person were 33.64 hours, 23.25 hours, 38.52 hours respectively. The percentage of delay hours of total labor hours for foodservice employees and supply person were 42.27% and 24.0%. The standardized work hours and the appropriate levels of foodservice employees of 17 elementary school foodservices were examined: The average rating of the foodservice employees work was 1.19 and British Insulated Calendarer Cables (BICC) allowance rate was 19.40% on the average. The total work hours of foodservice employees were 172.64 hours per week and levels of personnel were 4.53 persons. BICC allowance rate was applied: The standardized work hours per week was 180.95 hours and appropriate levels of personnel were 4.11 persons based on legal 44 working hours.
The purposes of this study were to: (a) measure the levels of job satisfaction with five facets of a job: the work itself, promotion, pay, supervision and co-workers and (b) investigate relationships between job characteristics and job satisfaction levels of the dietitians in school foodservice. Subjects consisted of 151 dietitians, with 91 in Seoul and 60 in KyoungKi-Do. The survey form was developed on modifying Job Descriptive Index developed by Smith, Kendall, Hulin and Job Characteristics Inventory developed by Sims, Szilagy, Keller. The responding rate was 81.7%. Data were analyzed for frequencies, means, t-test, ANOVA, Pearson correlation and multiple regression using SPSS PC Package. The results of this study were as follows: 1) Less than a half of the sample(40.9%) were 31 to 35 years, married were 62% and junior college graduates were 33.9%. 2) A striking majority of the respondents(81.7%) ranked work itself as the the most important aspect of their jobs. 3) The dietitians were the most satisfied with work itself, then supervision, co-workers, wage and promotion in decreasing order. 4) In relations of demographic factors to the job satisfaction, satisfactions with wage and co-workers were found significantly related to education. 5) Task identity was the most prevalent job characteristics. 6) The R2 for the multiple regression model was 0.26, indicating that 26% of the variance in job satisfaction could be accounted for the job characteristics. This model showed that friendship of job characteristics made the greatest contributions. The second was variety and the third was dealing with others. Especially dealing with others was negatively related to job satisfaction.
This paper was made for the purpose of research for direction on earth science subject matter of high school in Korea. For this purpose, we 1) reviewed the essence of science and goals and contents of science education, 2) reviewed the change of education of earth science subject matter, 3) investigated earth science teacher's opinion by questionnaire. The results were as follows: 1. Earth science subject matter must provide to students scientific process and knowledge - Process : to promote student's concerns for an interest in nature surrounding them, to help students develop and method in solving problems and its application for problem solving, recognition of variables of scientific method, to promote fundamental experiment and skills for scientific inquiry, etc. - Knowledge : provide systematic knowledge than simple rote, to help students understand concepts of recent scientific knowledge, contains STS, etc. 2. Earth science education must consider educational philosophy and educational psychology education of scientific literacy, partial professional education, conformity of development stage, sequence between school levels, attitudes to adaptation of scientific knowledge, method, skills and problem solving toward future positive attitudes to science, moral sense of science, minimum essense and difference of lines, open of upper limit, understanding the specific character of earth science, scientific knowledge development continuously, relationships of other subject matter, etc.
A study of eating behavior was conducted among 274 children of Nan Hyang elementary school, located in low income area of Seoul, where a school lunch program is not operated. During weekdays, 19.6% of children ate breakfast and 18.4% ate supper alone or with their siblings. The school provided boxed lunches for 10.5% of the children with governmental funds, who were chosen by the school based on their household income. But the percentage of the children skipping breakfast was 14.6%, lunch 10.3% and supper 8.0%. The results of nutritional analysis of the children who had three meals a day and those of children skipped one of the regular meals were compared. The group who had three meals consumed more nutrients except vitamin C than the group skipped meal (p〈0.01). Most common meal pattern was consisted of cooked rice, Kimchi and side dishes. When the children didn't have afternoon classes, 10.0% of the children ate Ramen only at home without any side dishes. Among the protein sources, the beans and bean products were the most common items. When we studied the three different lunches such as A) the boxed lunches provided by school, B) the boxed lunches from home and C) the lunches ate at home, the A) lunches provided the most common items. When we studied the three different lunches such as A) the boxed lunches provided by school, B) the boxed lunches from home and C) the lunches ate at home, the A) lunches provided the milk products, fruits, ice cakes·setc. Their favorite foods were fruits, yoghurt, Chinese black noodle, and sweet potatoes whereas being not prefered foods, were aromatic vegetables. It seemed that the increasing rate of working mothers and the overflooding of instant foods have caused to neglect children's meal management. To solve these problems, nutrition education and extend of school lunch programs should be emphasized.
We investigate the forms, the inquiry levels and the objective types in the inquiry activities of the Earth Science text book (Science I HA) that was reorganized at March, 1988 from the eight publishers, according to the reference of Schwab's(1966) inquiry level of experiment and the Klopfer's (1971) classification of objectives of science education. Ninty seven percents of the experiments belong to the 1st level of the Schwab' s(1966) inquiry level and there are no activities of the 3rd level. On the basis of Klopfer's classification, ninty eight percents of the inquiry objectives are included in the only four kinds (A.O, B.O, D.O, G.O) of the nine objectives, and the rest (C.O, E.O, F.O, H.O, I. O) of the important objectives that are indispensable to the inquiry process seems to be exclusive. Conclusively speaking, the inquiry ability of the students may not be cultivated by the experiments in present text-book.
In recent years, there has been a great change in the earth science. Introducing new theories such as sea floor spreading and plate tectonics theories, sophisticated geological phenomena including continental drift, earthquakes and volcanic activities can be scientificaly explained. According to the great change of the concept of earth tectonics, earth science curriculum of domestic and foreign secondary school are now adapting this new concept such as new global tectonics. The aim of this study is to improve curriculum and develope a new efficient teaching-learning method by analyzing the contents of the chapter connected with plate tectonics in the elementary, middle and high school curriculum. For this purpose, American ESCP, CEEP and Korean earth science textbooks were analyzed in terms of general concept, system and construction. As the results, newly setting up the plate tectonics chapter include the contents of the concept of the plate, plate movement and historical back ground of the new global tectonics.
When the educational curriculum that was established and proclaimed by the Ministry of Education in fact apply on the spot of education, to estimate that the intended objectives is being achieved and what should be improved by all means needs for the revise of a educational curriculum and the improvement of a instruction-study process. Here upon, I will try to carry out a part of research about the actual condition for the applience of a educational curriculum by analysis of the relation between the educational objectives and the achievement in the Geology unit of current high school science text book I (1988).
To investigate the nutritional contents of lunchbox of students of elementary school located in Sokcho city Kangwon province, the survey was conducted from April 23 to April 26, 1991. Main dishes and side dishes in lunchbox were weighed and nutrients were analyzed from food composition table. Total daily energy and nutrients intake were reach to RDA`s, except for intake of calcium, iron, vitamin A, vitamin B_2 and vitamin C. Children`s height was positively correlated with energy and protein intake. Fat intake was positively correlated with monthly income and intake of vitamin A was positively correlated with number of family. This survey suggests that it need nutritional education program and school feeding to improvement of nutritional status for children.
