Objectives: This study was carried out with 31, 519(16,653 boys, 14,857 girls) of elementary school students to investigate the prevalence of obesity at a district in Gwangju City. It can be applied to develope an educational program of the obesity control as basic data in this local area Methods: The data collected from May, 2004 to July, 2004 were analyzed by SAS PC+ 8.0 program. Children were selected depending on criteria from obesity index (%) by using physical index (height, body weight), and then subjects were classified into one of three groups according to the degree of obesity: mild(20~29.9%), moderate(30~49.9%), and severe($?50%{\cdot}$) obesity. Results: It showed that male elementary school students were higher and heavier than female elementary school students(p< .001) in every grade except the 4th grade(height) and the 6th grade ( body weight). The obesity rates of male students(11.6%) showed higher(p< .001) than those of female students(8.8%). Specially the 4th grade elementary school boys were higher than any other groups in obesity(13.7%). As a whole, the prevalence of obestiy showed mild(5.9%), moderate(3.8%), and severe(0.6%). Male students showed higher rate of obesity than those of female students. The obesity of male students showed higher rate than that of female students except 2-3rd grade elementary school students(p< .001). The obesity of 4~6th grade elementary school students showed higher rate than those of 1~3rd grade students(p< .001). Conclusions: The obesity rates of male students are higher than that of female students, and the obesity rates of 4~6th grade students are higher than those of 1-3rd grade students in the elementary school. Additionally, these results suggest that the program may be needed to prevent obesity of children.

The purpose of this study is to investigate the overall understanding of patterns by second- and third-grade elementary school students. For this purpose, 12 classes per grade were selected from 10 schools, and a 46-item test was administered to 216 second graders and 223 third graders. The results of the study showed that in most cases, there was no statistically significant difference in the understanding of patterns between second- and third-graders. The exception occurred regarding the 10 items of identifying the structure of a pattern: Second-graders did better than third-graders regarding 8 items, whereas vice versa regarding 2 items. The items that both second- and third-graders struggled with included finding multiple components of a given pattern, comparing the structures between patterns, and guessing a particular term in an open pattern. Based on these findings, this paper discusses second- and third-graders' understanding of patterns and suggestions for further instruction.

Purpose : Traditional herbal medicines may be overused in Korea. Expenditures and inaccuracies of hospital prescription are increasing gradually. So we investigated the frequency and nature of herbal medicine use among elementary school pupils. Methods : We interviewed students of three elementary schools located in Gwangju with survey papers. We analyzed 905 returned surveys. Results : They consisted of 421 males and 484 females. Five hundred ninety (65.2 percent) of pupils who have taken herbal medicines since birth. First grade made up 74.1 percent, 2nd grade 63.0 percent, 3rd grade 64.8 percent, 4th grade 63.3 percent, 5th grade 65.5 percent, and sixth grade 61.9 percent, respectively. The mean frequency of herbal medicine use was 3.2 times. 6th grade was 3.3 times, 5th grade 3.9 times, 4th grade 3.7 times, 3rd grade 2.7 times, 2nd grade 2.7 times, and 1st grade 2.6 times, respectively. The mean cost of herbal medicine use was from 50,00-100,000 won. The mean age of pupils who took their 1st herbal medicine was 55 months, 6th grade 67 months, 5th grade 58 months, 4th grade 54 months, 3rd grade 55 months, 2nd grade 51 months, and 1st grade 47 months. The most common reason of herbal medicine use was "looking weak, without disease." The rate of elementary pupils who had good effects was 63.7 percent; the rate of side effects was 4.5 percent. Conclusions : The rate of elementary pupils who took herbal medicines was high and gradually higher in lower grades. So, clinicians have to cope directly with this situation and to educate parents about herbal medicines.

The subjects of this study were 415 children in the first to third grade selected from 4 primary schools. Among them, 212 children belong to the experimental group, and 203 children were in the control group. The program was provided respectively to first, third and fifth grade children for 2, 4 and 6 teaching-hours from 2013.1.1 to 2013.12.19. To measure the effects of the program, the knowledge and attitudes on/toward smoking, self-concept were used as the research tools. Before and after program-implementation, there were significant differences in knowledge of smoking, but no differences in attitudes and self-concept. A smoking prevention program for primary school children should be applied step-by-step in conjunction with the regular education curriculum. In addition, the program should aim for long-term effects rather than short-term effects.

This study analyzed the science assessment items that were conducted by the paper and the computer-based assessment in the TIMSS 2019 pre-test, which is an international academic achievement assessment. We examined whether the test mode influenced the percentage of items answered correctly by each graders. As a result, there was no significant difference in the correct answer rates of science items according to the test media in 4th and 8th graders. Looking at the each graders, the difference in the percentage of correct answers was relatively large in the fourth grader rather than the eighth grader. In terms of items, the difference in the percentage of correct answers was relatively larger for the constructed items than the multiple choice questions. As a result of analyzing the content of science and assessment items on the influence of the test media, the multiple choice items showed little difference between the paper and the computer-based assessment items, but the answer-type items tended to have a lower percentage of correct answers than the paper-based assessment. In addition, by grade, 4th graders showed lower percentages of correct answers in the constructed items than 8th graders. This study provides implications related to the development and introduction of computer-based assessment in Korea, and suggests an educational implications for computer-based assessment to be well established as school evaluation.
