Purpose: Sodium intake in school meals is very high. Accordingly, many health problems have emerged. The objective of this study was to assess school dietitian's awareness and practice of sodium contents in urban and rural locations schools and suggest sodium reduction plan in school meal service. Methods: A total of 524 nationwide school dietitians from elementary, middle, and high schools in south Korea were surveyed using questionnaires to determine their awareness and practicing behavior for reducing high-salt contents in meals. Sodium reduction plan was then suggested accordingly. Results: Most school dietitians (83%, n=436) were aware of the necessities of sodium reduction in school meals. They were aware of optimum sodium levels at 700-1000 mg. However, the percentages of dietitians who had practicing behavior of using measuring utensils for seasoning were 20.7% (n=108), 14.9% (n=78), and 13.5% (n=71) in elementary, middle, and high schools, respectively (p<0.001). Dietitians in urban elementary and middle schools had significantly (p<0.01) higher practicing behavior of using measuring utensils compared to those in rural locations. Considering low levels of soup contents with high amount of leftover, the desirable soup portions to be reduced were '50-100 mL' (n=66, 12.7%) for elementary school and '100-150 mL' for middle school (n=62, 12.0%) and high school (n=57, 11.0%, p<0.001). Conclusion: Dietitians' awareness for sodium reduction was high but their practicing behavior was relatively low. Thus, continuous efforts are required to develop reduced-sodium menu by promoting the use of measuring utensils when preparing meals and by planning no soup meal day or educating students and teachers about the importances of reducing sodium in school meals.

The objective of this research is to understand the current field and composition of environment related terminology used in middle and high school textbooks, to find out uniformity and relationship between them, and development for the future establishement and replacement in the environmental education, simultaneously. The results of this study are as follows: 1. The terms used in middle school textbooks were found out to be 334, while those used in high school were 717. Total terms used were 870(759 kinds) and those recorded in the environmental terminology dictionary were 362 including synonyms. 2. Of those 870, 211 terms(24.25%) which were the same words have been used in interlinked connection with the Middle and High schools. While 136 terms(15.63%) have been used in the only middle, and 524 terms(60.23%) have been used in the only high schools. In middle and high school environmental tort books 211 (24.25%) terms were the same interlinked terms. Of those extracted terms, 136(15.63%) were used in the middle school 'environmental' textbooks and in high school, 524(60.23%) were used in 'environmental science' book. These results shows that there is big gap between middle and high school contents and we will need mere consideration in selecting the terms and better substance. 3. The same terminologies used in both middle and high schools were total number of 676. In those terms 257 kinds(76.26%) were used in middle school 'environmental' text books, and 563 kinds(78.52%) in high school 'environmental science' text books. Here are some details : 1) Terms used as same meaning but different in expression in middle school : 83 kinds, 192 terms(11.99%). 2) Differently expressed in the same tort book in kiddie school - 20 kinds(2.64%) in high school - 61 kinds(8.04%) 3) Differently expressed terms between middle and high school : 51 kinds(6.72%) 4) Same meaning in 3 expressions or more : 19 kinds 4. Of the examined terms 362(including 43 synonyms) were defined in environmental dictionary which is 41.8% of the total words. In the future specialization in utmost fields will be needed 5. When dividing those examined terms according to the middle and high school curriculum, the most terms were used in nature and pollution fields following environmental preserving, artificial environment and environmenatal counterplan. In middle schools the most used terms were in the field of environment pollution, preservation, counterplan, and santiation. There results reflects the education goals and objectives of middle schools. But for the middle school 'environment' curriculum moret uniform distribution are needed and for the high schools' 'enironmental science' program, the fields in artificial environment, industrization, urbanization, and sanitation should be intensified.

Recent studies on the learning of the science concepts indicate that most students have misconceptions of the science concepts. The misconceptions have their roots in the various aspects of teaching and learning situations. The textbooks used in schools have been substantiated as one of the sources of the misconceptions. Genetics has been recognized as one of the most difficult areas for high school students to learn. Therefore, this study had its objective to identify the misconceptions of genetics held by high school students and analyze the high school biology textbook as the source of the misconceptions. In order to indentify the misconceptions of the genetic concepts, the volunteer students were interviewed and genetic content and its sequence in the high school biology textbooks were analyzed. The misconceptions identified in this study are as follow: gamete formation, mitosis, trait expression, and allele and gene behavior in meiosis. This study found that the high school biology textbooks might be the source of those misconceptions. Based on the misconceptions identified, this study proposed direction for efficient instruction of genetics in high schools.

Excessive sodium intake leading to hypertension, stroke, and stomach cancer is mainly caused by excess use of salt in cooking. This study was performed to estimate the salt content in school meals and to compare differences in perceptions related to sodium intake between students and staffs working for school meal service. We collected 382 dishes for food from 24 schools (9 elementary, 7 middle, 8 high schools) in Gyeonggi-do and salt content was calculated from salinity and weight of individual food. The average salt content from elementary, middle, and high school meals were 2.44 g, 3.96 g, and 5.87 g, respectively. The amount of salt provided from the school lunch alone was over 80% of the recommended daily salt intake by WHO. Noodles, stews, sauces, and soups were major sources of salt intake at dish group level, while the most salty dishes were sauces, kimchies, and stir-fried foods. Dietary knowledge and attitude related to sodium intake and consumption frequency of the salty dishes were surveyed with questionnaire in 798 students and 256 staffs working for school meal service. Compared with the staffs, the students perceived school meals salty and the proportions of students who thought school meals were salty increased with going up from elementary to high schools (P < 0.001). Among the students, middle and high school students showed significant propensity for the preference to one-dish meal, processed foods, eating much broth and dipping sauce or seasoning compared with the elementary students, although they had higher nutrition knowledge scores. These results proposed that monitoring salt content of school meals and consideration on the contents and education methods in school are needed to lower sodium intake.

The ‘Ecosystem St Environment’ subject is included in the 7th revised curriculum for high schools in Korea, which ‘Environmental Science’ subject in the 6th curriculum was changed to. The 6th curriculum was announced in 1992 and has been applied till now, and the 7th revised curriculum was announced in the late of 1997 and will start to be applied in school education from 2001. The ‘Ecosystem & Environment’ subject is an integrated subject for liberal arts and science, which deals with environmental problems with approaches of natural science and social science. Its significance lies in understanding and solving environmental problems, and thus improving the quality of human life. And it is aimed to achieve the goal of environmental education in connection with ‘Environment’ subject in middle schools, which is one of the three optional subjects. This subject consists of six domains: human being and environment, ecosystem and environment, environmental pollution, global environmental problems ＆ their measures, environment and society, and environmental preservation. Compared with ‘Environmental Science’ in the 6th curriculum, in this subject less emphasis is put on environmental technological approach and more emphasis is put on environmental ethics and environmental social approach. On the contrary, one unsatisfactory point is as the following: locally integrated solutions of environmental problems are omitted: the organization of the textbook is more or less sporadical and sometimes overlapping; practical solutions are not concrete in writing the textbook and teaching it. The ‘Ecosystem & Environment’ subject which has been organized with new contents according to the 7th revised curriculum for high schools will be successful in achieving the given goal only when a lot of high schools select this subject and are taught effectively.

This study is to provide basic data regarding prevention of VDT syndrome by surveying the computer usage and understanding the VDT subjective symptoms. Data collection was done using a structured questionnaire among 617 students in middle and high schools in J city, Chonbuk province from 1 April 2002 to 20 April 2002. Modified and adjusted study tools were used which were based on previous studies on the actual computer usage and the VDT subjective symptoms, and the self-assessment tool for VDT syndrome by Moon et al(1991). Collected data were analyzed by SPSS program. The results were as follows: It showed 97.2% of students in middle schools and 97.6% in high schools to hold personal computer, 92.2% of middle school students and 84.7% of high school students commonly used computer at home. Communication was the obvious reason to use computer in 55.8% of middle school students and 71.6% of high school students. The mean of the VDT subjective symptoms among students in high schools showed $1.09{\pm}.69$ which higher than that of $.80{\pm}.59$ among students in middle schools (t=5.666, p=.000). Musculoskeletal symptom was marked the highest in the scoring of VDT subjective symptoms among students in middle and high schools. The higher grade, The more pocket money, The less breaks or exercise taken during computer use, The more they feel harmful about using computer, The actual time of computer longer than 3 hours per use were contributed to the higher score of the VDT subjective symptoms among students. There are suggestions following this study: To establish a systematic preventative program and management regarding the current computer use among students especially in relation to the VDT subjective symptoms. To develop better educational programs for parents regarding time-limit and to create appropriate environment in computer use.

In this study, we investigated the characteristics of students participating in Science Core high schools classes and their relevance to Positive Experiences on Science (hereinafter, PES), and factors causing PES, presented by the students of Science Core high schools. A total of 20 students and five teachers in four regions across the country participated in the in-depth interview, which were conducted with the focus group of students first, and then in-depth interviews with teachers. Based on the interview results, we explored teaching and learning experiences helpful to the PES, assessment experiences resulting in the PES, and ways to support Science Core high schools to enhance their PES. Students and teachers of Science Core high schools argued that students' participation will increase only if they engage in classes while drawing attention within the range that students can understand, students' PES such as scientific interest can be improved through experiments in which students choose topics or design their own exploration process, science competencies such as science problem solving ability and scientific thinking ability should be developed through exploratory experiment activities that fit the nature of science, etc. In addition, regarding ways to improve and support Science Core high schools to enhance PES, securing science class hours, restructuring the contents of science elective courses, and necessity of maintaining Science Core high schools are suggested. Based on the research results of science high school students' PES, ways to improve the PES of general high school students are discussed.

One of the most important objectives in science education is to develop students' science literacy. The purpose of this study is to analyze the relevance between biology instructional objectives in the 7th curriculum taught in elementary and secondary schools. For this study, 7 major parts in each grade were analyzed including cell, the form and function of plants, the form and function of animals, genetics, diversity, evolution, ecology, and environment. The strand map of instructional objectives is completed that represents the relation between the objectives. The summary of the results from this study is as follows. First, the concept about cells is not fully covered in lower grades including elementary schools. While the concept of energy metabolism is repeatedly covered, there is no concept of energy covered in learning the concept of energy metabolism in elementary schools. Second, the textbooks in elementary and middle schools have main concepts about the form and function of plants while those in high schools don't. The concept related to the part of the form and function of animals is repeatedly involved in the curriculum throughout the elementary, middle, and high schools. Third, the concepts such as genetics and evolution are involved in higher grades since these concepts are abstract ones. The part of genetics and evolution as well as diversity has no connection between grades in schools, so the development of "notion between" is necessary to relate these concepts with each other. Fourth, the 4 parts of diversity, ecology and environment, evolution, and the form and function of plants are covered in limited grade levels. The results of the relevance of gene in lesson goals will play an important rein as the primary material in developing the connection between textbooks in which lesson goals are closely related to each other throughout all grade levels in elementary, middle and high schools.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through $\chi^2$-test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teachers. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC than those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.
