Primary students' conceptions on the atmospheric pressure and its related concepts were investigated. Samples consisted of 41 5th grade and 43 6th grade primary school students. Two types of research methods were used: 1) the open-ended written questionnare;2) paper-pencil test. Naive theories on the atmospheric pressure and its related concepts were numerous. For example, 80% students thought that as we go higher into the atmosphere, the atmospheric pressure becomes greater. Also, 50% students thought that the hot air had greater the atmospheric pressure than the cold air. This study was also discussed the teaching strategies to overcome these naive theories on the atmospheric pressure and its related concepts.

The main purpose of this study was to analyze and identify factors related to changes in visual acuity of primary school students over one year period. The data for this study were collected from 980 students in the first to fifth grades of one elementary school located in Koyang City, Kyungki Province. The visual acuity tests of students and self reported questionnaires for the students and their parents were administered in 1995 and 1996. The data were analyzed by using SAS PC. The results of the study were as follows. 1. Visual acuity in both eyes is significantly lower in girls than in boys. 2. Overall visual acuity of the students decreased over the one year. Notably, decreases in visual acuity were statistically significant during the transition from the first to the second grade and from the third to the fourth grade. 3. Students with visual acuity ranging from 0.4 to 0.7 and those above 1.0 in 1995 showed a significantly lower acuity in 1996 than other students. 4. Students who needed glasses in 1995 showed significantly lower visual acuity in 1996 than those without glasses. 5. Other factors related to visual acuity are lights in the classroom, difficulty reading a blackboard, posture of children while watching TV, and distance from the TV set. Some of these factors may be the result of students' already poor visual acuity rather than causes of the decrease. In conclusion, many elementary school children experience significant decrease in visual acuity and need special intervention to maintain or improve their visual acuity.

The purpose of this study is to analyze elementary students' understanding the relationship between perimeter and area in geometric figures. In this study, the questionaries were used. In the survey, the subjects were elementary school students in In-cheon city. They were 86 students of the fifth grade, 86 of the sixth. They were asked to solve the problems which was designed by the researcher and to describe the reasons why they answered like that. Study findings are as following; Students have misbelief about the concept of the relationship between perimeter and area in geometric figures. Therefore, 1 propose the method fur teaching about the relationship between perimeter and area in geometric figures. That is teaching via problem solving.. In teaching via problem solving, problems are valued not only as a purpose fur learning mathematics but also a primary means of doing so. For example, teachers give the problem relating the concepts of area and perimeter using a set of twenty-four square tiles. Students are challenged to determine the number of small tiles needed to make rectangle tables. Using this, students can recognize the concept of the relationship between perimeter and area in geometric figures.

The Korea School Lunch Program mandates that school meals should safeguard the health and well-being of our children. School meals provide a nutritious diet that contains at least ⅓ of the daily Recommended Dietary Allowances of necessary nutrients at reasonable prices. This study was performed to assess the nutritional management of primary school meals, and to provide basic data for improvement of school meal nutritional guidelines. Three hundred and thirty six dietitians who worked at primary schools were recruited using a stratified sampling method. A survey was done by e-mail with a set of questionnaires about nutritional meal management. During school lunch planning, dietitians referred nutrition standards with priority, followed by students' food preferences and food hygiene. They considered energy as a most important nutrient during primary school lunch planning, followed by protein and calcium. Protein is usually over-served, whereas iron, vitamin A and calcium are usually under-served during primary school meal planning. For first and second grade primary students, grains, meat and vegetable side dishes seemed to be large compared to their eating capacity. Over 92% of school dietitians agreed the needs of food group standards for primary school lunch program. For making a checklist of the school lunch program, energy, protein and calcium were highly recommended, and meat.fish.egg group, vegetable.fruit group and dairy group were also highly recommended by school dietitians. Cooking method was also highly recommended. School dietitians proposed that remodeling of school kitchens and new cooking machine were the most important factors for improving school lunch system. These results suggest that food standards should be established for health-oriented nutritional management of primary school lunch programs. Nutritional checklists could include nutrient-rich foods and food groups, and items about cooking methods.

This study aimed to investigate primary students' science-related attitudes through the literature review. Ninety-four papers published in domestic science education journals, since 1990, were collected and were followed by content analysis. In this study, science-related attitude was conceptualized as attitude toward science, scientist, science-related occupations, and school science, which is composed of cognitive, affective and behavioral domains. Based on the conceptualization, the instruments used for measuring students' attitudes were analyzed. The analysis of definition of science-related attitude in the articles showed different foci on cognitive, affective and behavioral domains. To suggest the effective instruction for enhancing students' science-related attitudes, this study identified students' attitude with gender, grade, residence and achievement level. The result showed that male, urban, higher-grade and better performed students had more positive attitude than female, rural, lower-grade and less performed students. As for the factors in science-related attitude, I categorized the factors into personal, environmental and pedagogical aspects, and found that psychological elements in all domains were most influential to students' change of science-related attitudes. It is interesting to note that students showed dichotomous views about experiment and that task-oriented instruction failed to enhance students' attitude. Based on the research findings, this study suggests effective instruction for improving students' attitudes and future research for science education.

This study aims to illustrate the value of teaching English drama in the course of teaching primary English and suggests a model for primary English drama in an English camp for Children. Drama is the world of assumption where language is used just like in real life. It has a positive effect on foreign language learning by encouraging the operation of certain psychological factors which facilitate oral communication. Dramatic techniques such as storytelling, role play, chant, song and games can be used in the EFL classroom to help bring about such results. Meanwhile, making a primary English drama in an English camp for Children would be practical mode to attain the essential purpose of EFL teaching particularly to get over the drawbacks of Korean students' communicative competence under the school's inflexible EFL education curriculum. In this paper, I will present the effectiveness of English drama and the skills for using it with ESL students and suggest some notes that can be used to reinforce the goals set out from the position of the teacher, student and teaching material. It is confirmed that the trained leader, students' affirmative attitude and systematic teaching materials are needed to maximize the effects of drama activities. In addition to that, there will be showed a model of instruction targeted to the primary students learning English in an English camp for Children.

Objective : From an analysis of a community outbreak of measles in Youngju, Gyeongbuk, in March 2000, the authors evaluated the effectiveness of the measles vaccination and its determinants to Provide an epidemiologic basis for the establishment of a vaccination policy. Methods : Information was collected regarding the vaccinations from the health records of four primary schools and through a questionnaire surrey of the parents of students in two middle and two high schools (N=4638). Measles cases were surveyed from the patient list of each school and from case reports in the public health center. The attack rate and vaccine effectiveness of measles was evaluated by school; grade; frequency, region, and institution of vaccination. Results : The attack rate cf measles, 6.3% among the total subjects, was higher in middle school students (15.8%) than in primary (2.0%, p<0.05) and high school students (8.9%, p<0.05). The attack rate of the unvaccinated group was 4.6-fold higher than the vaccinated group in primary schools (p<0.05). Vaccine effectiveness was 83.2% among lower graders of primary schools, 34.0% among higher graders of primary schools,26.1% in middle schools, and -7.0% in high schools. In multiple logistic regression analysis, grade in school (odds ratio, 0.77; 95% CI=0.67-0.87) and frequency of vaccination (odds ratio, 0.57: 95% CI=0.37-0.58) were significant predictors of the outcome. Conclusions : We concluded that the explosive outbreak of measles in this area resulted from both inadequate vaccination coverage and secondary failure of vaccination. There was no evidence of any effect of the cold chain system on the vaccine failure.

Objectives : The purpose of this study is researching for correlation between Moire topography results and questionnaire which include obesity rate, height, weight, posture, pain aspect (low back pain, headache, fatigue, neck pain etc), studying posture, school attendance method, menarche. Methods : The authors practiced Moire topography and questionnaire for primary & middle school 24,419 students [male 12,843, female 11,576] in Jeonbuk, korea in 2002. After we distinguished students who had abnormal finding in Moire topography and statistically analysed the data. Results : According to this research, the abnormal finding in Moire topography results was 37.3% (9,105 students), and students needed X-ray re-examination were 3.9% (953 students). According to statistical analysis, male/female and primary/middle school students have no difference in deformity degree of the body surface examined by Moire. Height and weight have low correlation with deformity degree of the body surface examined by Moire and menarche, pain aspect have no correlation. But, school attendance method by bicycle and $90^{\circ}$upright sitting in study posture is the best way to decrease the deformity degree of the body surface examined by Moire. Conclusions : Following this research, throughout Moire topography could detect trunk asymmetry that couldn't be found existing X-ray examination, and school attendance by bicycle and $90^{\circ}$upright sitting in study posture is good for school students to prevent back deformity.
