본 논문은 칠교판의 일곱 조각을 모두 사용하여 만들 수 있는 볼록다각형의 개수를 탐구 주제로 한다. 본 탐구 주제는 현재 두 가지 방법을 통해 증명이 되었다. 한 가지 방법은 피크의 정리(Pick's theorem)를 이용한 방법이고, 다른 한 가지는 和々草의 방법(2007)이다. 하지만 두 방법은 초등교육과정 수준을 벗어난 내용을 포함하고 있기 때문에 초등에서 다루기에는 무리가 있다. 이 논문에서는 초등수준에서 적용이 가능한 증명 방법인 단위넓이를 이용한 방법과 최소넓이를 이용한 방법을 대안으로 제시한다. 그리고 새롭게 제시한 증명 방법이 초등수학영재에게 실제 적용 가능한지를 알아보기 위해 총 4차시에 걸친 수업 프로그램을 구성하였고, 이를 A초등학교 5학년 학교단위 영재학급 학생 5명을 대상으로 적용하였다. 그 결과 5학년 초등수학영재 수준에서 칠교판으로 만들 수 있는 볼록다각형의 개수를 정당화하는 것은 가능함을 보였다.

The purpose of this study was to serve as a basis for more effective sex education, by examining the influence of obscene media on elementary school student's sex consciousness. For attaining the purpose, the research questions were posed as follows: 1) What's general characteristics of elementary school students? 2) How much are elementary school students exposed to obscene media? 3) Is their sex consciousness different according to the degree of being exposed to obscene media and the appearance of secondary sex characteristic? The subject of study were the 400 male and female students who were in the sixth grade at elementary school in the city of Paju. The questionnaire survey was conducted to find out their general characteristics, sex consciousness and degree of being exposed to obscene media. The conclusions were as follows; 1) Basic Information 94% of the students investigated were living with their parents. The greatest number of their parents were in their fourties. Concerning the religion of their families, 47.5% belonged to Christianity or Catholicism. 47.3% got in touch with obscene media, which indicated that the harmful influence of that media was great. Their basic knowledge of pregnancy was very poor, as 27.2% weren't sure whether being pregnant could be caused only by shaking hands, hugging or kissing. 34.7% considered it a natural behavior to contact the other sex. Regarding their practice of sexual behavior, they'd have an experience of hugging or kissing. 2) Group Comparison The female students underwent the appearance of secondary sex characteristic faster than the male students. As a result of examining if their degree of being exposed to obscene media was affected by the presence or absence of secondary sex characteristic, no statistically significant difference existed in all the groups: the entire group, male student group and female student group. There appeared, however, statistically significant differences between male and female students, as the number of male student who hadn't yet been exposed to obscene media was less than that of female student who hadn't. And the number of male student who had been much exposed to obscene media was more than that of female student who had. 3) Sex Knowledge, Sex Attitude and Sex Practice The extent of making contact with obscene media didn't make statistically significant difference to the sex knowledge of all the groups. But more extent of getting in touch with obscene media led to more sex attitude and sex practice in the entire group. However, as a result of analyzing these things by the presence or absence of secondary sex characteristic, it's found in general that the group that had secondary sex characteristic possessed statistically better sex knowledge than the other group that hadn't. For the male students, there appeared little disparities in three subareas of sex knowledge, sex attitude and sex practice. For the female students, however, the group that had secondary sex characteristic owned better sex knowledge than the other group that hadn't, and the former group looked upon sex attitude as more natural.

This research was conducted to provide basic document on efficient health promotion behavior program that elementary school students can use from elementary school course to enhance health promotion behavior for healthy life by checking out the degree of the most influential factor for health promotion behavior about elementary school students who establish lifelong health habit, and by checking out the relation between the degree of self-efficacy and health promotion behavior. The number of subjects of this research was 598. They were all elementary school students from the sixth grade students of the 5 cities of the Kyeong Nam province. We conducted questionnaires and did statistical analyses by using 592 papers which were suitable for date analyses with SPSS. The conclusions were as follows; A. The degree of self-efficacy The degree of self-efficacy of elementary school students was more than average. The degree of self-efficacy on physical activity was the highest and the degree of self-efficacy on self-fulfillment was the lowest. The degree of self-efficacy of girl students was comparatively higher than that of boy students. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest in health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. B. The degree of health promotion behavior Although the degree of health promotion behavior of elementary school students was a bit lower than the degree of self-efficacy, it was higher than average. The degree of health promotion behavior on physical activity was the highest. But the degree of health promotion behavior on health of their own was the lowest. The degree of health promotion behavior between girl students and boy students was the same. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest In health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. C. The relation between self-efficacy and health promotion behavior When the degree of self-efficacy was high, the degree of health promotion behavior was high too. So there was high positive relationship between self-efficacy and health promotion behavior. Physical activity showed the highest relationship. The order of strong relationship run as follows. Relationship with others, self-fulfillment, management of stress. The higher self-efficacy which was a recognizable factor on health behavior, the higher the degree of health promotion behavior. It is being revealed that many modem chronic diseases are cause by accumulated careless attitude on harmful health habit and lack of self-control. The behavior of keeping healthy and enhancing health is more firm when they have high self-efficacy which is believing their own conviction. So, When we teach elementary school students health promotion education at school, we should try to enhance their own self-efficacy rather than just instill simple information about health. By doing so, we can help them change their attitude on health. Then, they could enjoy life-long healthy life.

It will prevent the serious alcohol problem for adolescents and be the opening-learning according to learner's needs beyond the traditional classroom learning which has limitation of space and time. Method: This research designed based on web-based instructional system design by In-sung Jong(1997). This study was performed on the elementary school students who are the six grade in M city. The number of experimental group was 72 and control group's number was 72, totaled 144. Data were collected from September, 30th, 2004 to November, 5th, 2004, totaled 37days. The pretest and the posttest for web-based alcohol preventive education program were tested about knowledge and attitudes toward drinking. After the performance, the posttest was also tested the effect of this program under items by the interest of web-based learning, satisfaction, adequateness of material and so on. The data analysis was done using SPSS/Win 11.0 program. Result: The results of this study are as follows: 1) Compared with control group, experimental group which was educated the web-based alcohol preventive educational program for elementary school students was improved the knowledge on drinking, thin there was no significant difference. However, it showed significant difference between two groups after education. It was, therefore, partially supported. 2) Compared with control group, the experimental group which was educated the web-based alcohol preventive educational program for elementary school students showed significant difference in attitudes toward drinking. After education, it showed no significant difference attitudes. toward drinking between experimental group and control group. It was, therefore, partially supported. 3) The degree of learning motivation was an average.595 of 1 after learning applied to by the web-based alcohol preventive educational program for elementary school students. Then, it is relatively more higher than the result of existing studies. So, it showed that the motivation was done well. 4) Correlation among study variables It showed that there was the significantly positive correlation between knowledge and attitudes toward drinking of pretest experimental group. Also, there was the significantly positive correlation between attitudes toward drinking and learning motivation of pretest and posttest experimental group. Conclusion: I found that the web-based educational program helps the elarning process for the health education in the school field which the instructional materials lack. As a result, the web-based education motivates the learner's pleasure and promotes the learners interest. Also, it is possible for students to learn according to their own learning pace, repeated learning and active learning participation in the necessary parts. Therefore, I think the web-based educational program is worth as a intervention to get positive influence for the health education.

The purposes of this study are to do surveys of the state of health and dental health behaviors of higher grade students in elementary school and their mothers, to investigate the relationship of students' dental health, and to apply those results to the systematic and efficient dental health care. The subjects were totally 618 people, including 309 elementary school students in 4th, 5th, or 6th grades and their mothers in Pusan. The questionnaires were used as instruments, which were made by the researcher and related with other preceeding studies. The content validity of the instruments was tested by two professors of nursing. Dental checking were conducted by an expert of dental sanitation, according to the standard of the World Health Organization. The period of collecting data was 20 months from October 20th to December 20th in 2000 and the collected data were analyzed by SAS program and classified as the real number, the percentage, the mean, the standard deviation, t-test, and F-test. In conclusion, there is no significant correlation between grades and treated or treatment-needed permanent teeth. There is the highest significant correlation between treated or treatment-needed permanent teeth and students' dental health behaviors. There is high significant correlation between mothers' dental health behaviors and students' dental health behaviors. Also, There is significant correlation between mothers' state of dental health and students' state of dental health. From the results of this study, the students' dental health behaviors are the most important variables in the students' state of dental health. But both boys(9.48) and girls(9.97) get the low marks on the total mark 15 about brushing, which can be self-controlled. Therefore, the developments of dental health guidance in education about dental health by mothers or the educational courses in schools, such as brushing educations by the experts, dental health education, brushing after lunch, or the various equipments in brushing, should be accomplished. Above all, behavior-centered education should be conducted instead of knowledge-centered education.

The purpose of this study was to examine dietary attitudes of students and changes in their attitudes toward the school lunch service. The participants of the study were 483 students ranging from third grade elementary school students to middle school sophomores living in the Seoguipo area of Jeju Island. The subjects were asked to complete questionnaires under the supervision of their teachers or dietitians, and data were grouped into elementary school 3rd and 4th grades, elementary school 5th and 6th grades; and middle school 1st and 2nd grades for each gender. There were no significant differences among the groups with respect to their regularity of food intake, dietary considerations, or the frequency of imbalance in their diets. In the case of female participants, their frequency of snacking decreased as their grade level increased. In general, the overall changes in dietary attitudes became more negative as their grade level increased. Male students demanded increased serving sizes of both staple food and side dishes, while female students demanded increased serving sizes dishes, but not staple food as their grade levels increased. there was also an increase in the number of student sin higher grades who discarded or did not eat enough their entire meals. The major reasons for not eating the food were : no taste to the food and not proper saltiness of food. These results may suggest that school dietitians need to pay more attention to increased taste and proper seasoning of meals. Students suggested that the school lunch service should be continued, but that it needs improvement. Students in higher grades were more aware of the importance of the environment in which the meal was provided. Also, an early education in nutrition and healthy diets seemed important in preparing them for following a healthy lifestyle in later life.

Purpose: To understand the differences and correlations of the knowledge of oral health, behavior, self-efficacy, belief, and the number of cavities in accordance with the general traits of elementary school students. Methods: The survey was conducted at 2 elementary schools in D city, which 740 respondents were analyzed. Results: A group of students who have received health education has plentiful knowledge of oral health and have more cavities. Also, a group of students who have been to dental clinics recently have more knowledge of oral health, follow guidance on oral health, and have high level of belief in health. The more knowledge of oral health the students have, the better they behave for oral health and the higher self-efficacy and belief in oral health become. Students with higher self-efficacy show more knowledge of oral health, more appropriate behavior, and stronger belief in oral health, while the number of cavities are much less. Conclusion: Health education contributes to improving the level of knowledge of oral health. Comprehensive programs beyond simple introduction of knowledge will be needed to improve behavior, self-efficacy, and belief in oral health. It is recommended to include a health clinic within a program for improving oral health in school so that it can help more students get oral health.
