In parallel with social and economic progress, motives of patients to consult dentists have increased and diversified. An increasing number of people visit dental clinics to improve their facial appearance and masticating functions deteriorated largely due to malocclusion. There is also greater interest in and concern as well as demand for teeth alignment treatment among people. Under this situation, it is required to find and suggest ways to enhance quality and profitability of dental care in view of managerial needs for dentists to cope with changing circumstances. This study, thus, aims to measure satisfactions of orthodontics patients and to determine the elements influencing their satisfactions. For this aim, a survey was performed for 20 days from March 7th to 26th, 2005 by means of questionnaires distributed to randomly selected samples, resulting in following conclusions: 1. From comparison of satisfactions with dental service by their elements, higher satisfaction was reported from orthodontics patients in the element of dental hygienists(4.21). Least satisfaction, however, was found in the procedure for treatment and waiting hours(3.73). 2. By gender, male orthodontics patients turned out to be more satisfactory with dental service than females. In terms of intention for return visits, both male and female orthodontics patients showed higher satisfaction than non-orthodontics ones. 3. As for satisfaction with dental service by age of orthodontics and non-orthodontics patients, with regard to intention for return visit, orthodontics patients of all ages showed to have higher grade of satisfaction. 4. Regarding satisfaction with dental treatment by orthodontics and non-orthodontics patients by monthly income, Dental hygienist with intention for return visit, the higher the satisfaction of orthodontics patients. 5. In regard to satisfaction with dental treatment by education, higher satisfaction was expressed by orthodontics patients with elementary school education kept dentist, dental hygienist and internal and external environments. As a result from this study, we knew that dental service of the orthodontics patients is higher satisfaction than that of the non-orthodontics patients.

The aim of this study was to examine and compare the eating habits, dietary intake patterns and nutrient intake status of children with and without atopic dermatitis by questionnaire during July, 2008. A total 388 subjects of 5th and 6th grade elementary school children (AG: atopic group, n=65, NG: non-atopic group, n=323) in Seoul and Ulsan areas participated in this study. The questionnaire included general characteristics, dietary habits, and atopy-related food frequency. One-day 24 hour recall was collected to estimate nutrient intakes of the subjects. The data were analyzed by Chi-square test for food frequency analysis and by t-test for nutrient intakes. Atopy-related foods included milk, buckwheat, beef, pork, chicken, crab, egg, mackerel, peach, and tomato. From the findings, AG had a more irregular eating habit than NG (p<0.05). In case of food frequency, AG tended to consume more atopy-related foods than NG (p>0.05). The nutrient intakes of AG were significantly lower than those of NG (p<0.05), but only intake of animal iron in AG was higher than NG (p<0.05). NG consumed more protein than AG (p<0.05). Although milk was a noted hypersensitive allergic food, frequency and the amount of milk intake were not significantly different between two groups. In conclusion, atopic children had eaten more atopy-related foods and less nutrient intakes. Therefore, it is necessary to educate on good nutrition and guide atopic children and their parents.

State curiosity and state anxiety in the science learning have a great influence on academic performance and achievement. Since the levels of state curiosity and anxiety can change at any moment, it is essential to identify the levels of student's state curiosity and state anxiety throughout the course of science learning. Accordingly, we assessed the changes in state curiosity and anxiety levels sensed by 5th- and 6th-grade elementary school students depending on their exposure to the violation of expectation. To this end, we classified science learning into three situations: confronting a scientific task, checking the result, and learning science concepts. As a result, there was no significant difference in state curiosity level of the nVOE group who confronting the result consistent with their expectations in checking the result after confronting a scientific task, but the state curiosity level of the VOE group who facing violation of their expectation increased. In the VOE groups, there was no significant change in the state curiosity level of the VOE-R group who correctly inferred the reason for the result, but that of the VOE-FR group who could not correctly inferred increased. The state anxiety levels of the VOE and nVOE groups decreased after checking the result of the task. The state anxiety level also declined in the VOE-R group. In contrast, there was no significant change in state anxiety level of the VOE-FR group. In learning science concepts of the result after checking the result, the state curiosity of the VOE, nVOE, and VOE-FR group all faded. No significant change was observed in the state anxiety level of the nVOE group, whereas the VOE, VOE-R, and VOE-FR group presented a decreased state anxiety. This study discusses the educational implication of these findings and its outcomes are expected to broaden the understanding of emotional states of students in science learning.

This study aims to design mathematics-integrated classes that cultivate artificial intelligence (AI) thinking and to analyze students' AI thinking within these classes. To do this, four classes were designed through the integration of the AI4K12 Initiative's AI Big Ideas with the 2015 revised elementary mathematics curriculum. Implementation of three classes took place with 5th and 6th grade elementary school students. Leveraging the computational thinking taxonomy and the AI thinking components, a comprehensive framework for analyzing of AI thinking was established. Using this framework, analysis of students' AI thinking during these classes was conducted based on classroom discourse and supplementary worksheets. The results of the analysis were peer-reviewed by two researchers. The research findings affirm the potential of mathematics-integrated classes in nurturing students' AI thinking and underscore the viability of AI education for elementary school students. The classes, based on AI Big Ideas, facilitated elementary students' understanding of AI concepts and principles, enhanced their grasp of mathematical content elements, and reinforced mathematical process aspects. Furthermore, through activities that maintain structural consistency with previous problem-solving methods while applying them to new problems, the potential for the transfer of AI thinking was evidenced.

The purpose of this study was to investigate the influences of teaching mathematics for social justice on students'interest towards mathematics and perceptions of mathematical values. Eighteen 6th grade students, at B elementary school in Seocho-gu, Seoul, who wished to involved in the study participated in the 10 hour lessons. During the lessons for social justice, the researchers analyzed the students' reactions in the lessons according to the three categories: Perceiving given problematic situations of social conflicts, searching for problem-solving methods based on mathematical analysis, and changing social behaviors to solve life issues through mathematics. They also examined changes of students' interest towards mathematics and perceptions of mathematical values through the activities and reactions using the preliminary questionnaires, observations of lessons, and students' activity sheets. The research results showed that the students perceived mathematics as a tool for social justice in mathematics lessons, tried to find problem-solving methods based on mathematical analysis, and expressed their active social behaviors by cultivating the will of practice to solve life issues through mathematics. Based on those findings, the study reached the following conclusions. First, the students recognize many of the social problems in their societies as social justice regardless of their economic levels. Second, learning activities need to design in a way that students can accept the social problems as realistic situations in teaching mathematics for social justice. Third, students look at the world from a mathematical perspective, have interest in mathematics, and recognize the values of mathematics in teaching mathematics for social justice.

The purpose of this study was to ascertain high school student ideas on the motion of the Earth and moon by cognitive level. For this study, five students determined to be of high, middle and low cognitive level selected from 73 10th-grade students at a high school located in Suwon, Gyeonggido. The results of this study were as follows: first, students at the high cognitive level had comparatively more logical and scientific conception on the revolution and rotation of the Earth and moon. second, students at the middle cognitive level, generally had a passive learning attitude to unconditionally memorize learned contents, so they were apt to forget learned contents, also their recognized conception was not enlarged. In addition, they had native theories, intuitive ideas and misconceptions as well as made logical errors in the course of explanation for the motion of the Earth and moon. In the course of explanation for the phases of the moon and the cause of change of season, because of their scientific conception, the students made more and more errors in conception. finally students at the low cognitive level were not willing to think logically and positively and were very passive in the attitude to recognize conception. In addition, they have learned helplessness on the grounds that they have low scholastic achievement specially in science.
