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.

The earth science was set down as a regular subject of high-school curricilum in 1956 and has been constantly transited since then. This study is to discover the theoretical basic of science education by analyzing the background of formation of the curriculum and the process of transition. The aim of this study is to give an important suggestions for the future Earth Science Education. The summary of the study and suggestions for the sixth amendment of Earth Science curriculum are as follows 1. To promote the development of Science Education, Science subjects should be decided to be a compulsory subject by authority and supported financially. 2. It is necessary that the Earth Science be selected as a required subject in both human and natural course ; at least 4 unit for the human study course, and 8 unit for the natural course. 3. In the sixth amendment of curriculum the Earth Science should be fixed as a regular compulsory subject and both experiment and practice should be reinforced.

This study was conducted a comprehensive sarvey of 39 elementary schools operating school lunch program in Seoul area. The purpose of this study was to investigate the realities of school lunch program. This method of this research was based on the interview survey with dietitian working at each school with prepared questionaire. The survey was conducted for 16 days from Dec. 5 to Dec. 20., 1990. The results of this study were as follows ; (1) The average numbers of children supplied with food were 1, 244 for each school. It was about 44.3% of the students enrolled in the school. The average feeding cost was 738 won per a child for a day. (2) Only one school was operating nutritional education as a regular educational program, and others were operating nutritional education off and on. (3) All nutrient intake except energy were higher than the RDA for school lunch program. (4) The ratio of animal food was 46.2%, and that of vegetable food was 53.8%. (5) The ratio of schools without sterilizer cabinet came to 56.4%, and that of schools without warmer was 97.4%. (6) The facilities for drainage, lighting, ventilation, anti-rat of a cookery were comparatively good.

An ecological study of food and nutrition was conducted among 198 children, 6 to 12 years old, of the Songmyun elementary school and Samsong elementary school, located in remote villages of Chungchun-myun, Goisan-gun, Chung Buk Province between July 11 and 16, 1988. The results were summarized as follows. In regard to frequency of skipping breakfast, 3.3% of subjects skipped every morning; 15% often skipped; and the others never skipped. The most common reason for skipping a meal was lack of appetite. 6.6% of subjects often skipped an evening meal because of delayed meal preparation by a mother who returned home late. The survey found that 5.1% of subjects skipped a lunch at school. The reasons for skipping lunch were the mother’s being too busy to prepare a boxed lunch; a school bag too heavy to carry for a long distance to school; no adequate side-dishes for the boxed lunch. Growth patterns of those children having poor food habits, were reflected in lower figures in arm circumference and weight for height. The percentage of children having meals with their family on weekdays was 84.7% for breakfast; 85.6% for evening meal. About 7% of subjects had many dislikes and 74.1% had some dislikes in what they ate; 18.9% had good food preferences. There was a strong correlation between appetite or food preferences and anthropometric measurements or nutrient intake. Boiled rice was the predominant dietary staple, and principal sources of protein taken by subjects at home were soy beans and soy products. Regarding the boxed lunch prepared at home, most popular was one with only one kind of side-dish, including kimchee. 43.4% of the side-dishes were prepared with vegetables only. As for between meal snacks, milk and milk products, fruits and breads were popular among the subjects. The survey found that the children liked fruits, yogurt, corn, Chajang noodle; in contrast, lowest preference was for soup made with bones, curried meat with rice, and aromatic vegetables. The survey discovered a local dietary characteristics; 46.2% of the children customarily ate frog meat, an unconventional food.

Students' understanding of atmospheric pressure concept was investigated by using the questionnaire method. The results indicated that students' understanding of atmospheric pressure concept was superficial and very various. Despite students' correct answers, their understandings are partial and they have many misunderstandings which are often associated with scientific terms. Especially many students didn't understand the method of measurement, definition and the reason of variation with altitude of atmospheric pressure. The implications of these findings for science teaching are discussed.

1. The aim of this study is to find the theoretical foundation of science education and to offer a basic materials and efficient suggestions for the 2000s Earth Science by analyzing and comparing the new curriculum amended in 1988 and the old one amended in 1981. 2. The main contents of this study is to find the problems in curriculum and to suggest the way to improve the curriculum by analyzing and comparing the new and old curriculum. 3. The problems that may appear in the new curriculum are as follows. (1) It's hard to expect the normal Earth Science Education in high school because Earth Science is designated as an optional subject in natural course. (2) It is contradictory to relation in learning to unify the Earth Science I and Biology I into Science I in new curriculum. (3) If the new curriculum goes in effect it is natural that Earth Science teachers quality should be lowered because able students will avoid entering the Department of Earth Science Education in university. 4. The suggestions to help improve the Earth Science curriculum in 2000s are as follows. (1) For the normal Earth Science Education, Earth Science should be designated as a required subject in civic science course as well as in natural course in high school. (2) The aim of Earth Science Education should be amended not to be dicipline centered curriculum but to satisfy the future society or individual's desire (3) The intergrated science should be researched profoundly and it is necessary to name Earth Science Geophysics, which is unified with physics. (4) Natural science curriculum should be amended by the committee constituted with the specialist in science education, scientists, and science teachers ; it is not proper that science curriculum be reached and discussed by an reorganization in which a few specialists in science education join.
