Teaching aids Robot Education, through early education and contests, is very commonly known to elementary school students, their parents and teacher. However, not only we do not have complete knowledge of how robot education for after school performs, but also we lack a proper management skills in educating new teachers and running a structured program. Thus, through this research, we would like to identify the problems in teacher's knowledge and how the robot education is running according to provinces, size of cities, public private school, and size of schools and provide proper and most effective way of teaching after school robot class. According to the result of this research of running 'Robot class' in different area, sub-areas and size of schools, there was a meaningful difference and the biggest problem in performance was the class organization. In addition, about the expectation through after school classes, the research showed that the teachers expect lower cost of private education and improvement in creativity the most.

The purpose of this study was to investigate the practice of nutrition education and perceptions for implementing nutrition education in elementary schools. In this survey, 833 dietitians, 808 principals and 3,141 teachers across the country were asked about the present status and problems as well as necessity, methods, education time, education subjects and the proper nutrition educator ratio. The results of the survey showed that only 4.2% of dietitians implemented nutrition education during regular school hours or through special activities. Many subjects responded that the reasons for not practicing nutrition education were systematic problems of lack of time due to too much food service work. Especially, many rural area dietitians responded that the reason was lack of time due to joint management and cooking. Many dietitians, principals and teachers responded that the placement of one nutrition teacher in every school is needed to resolve these problems. Other solutions suggested were the introduction of a dietitian internship, and the modernization of foodservice facilities for principals and teachers. Of those surveyed 98.4 percent of principals and 95.5 percent of teachers responded that nutrition education is urgently needed. Many subjects also responded that the first three years of elementary school are the most proper time for nutrition education and it is best that these lessons are reinforced at least once a month through discretional or special activities. Survey participants responded that the proper ratio for nutrition educators is 400-800 persons for dietitians compared to less than 400 persons for principals. In conclusion, it is hoped that this study will be able to provide a foundation of data for implementing a systematic nutrition education program by nutrition teachers in elementary school.

This report describes 3 cases of cleidocranial dysplasia (CCD) and presents relevant findings on long-term follow-up radiographic images of impacted permanent teeth with delayed eruption. Radiographic images of 3 CCD patients were reviewed retrospectively. These images were mainly composed of panoramic and skull radiographs, and the follow-up periods were 3, 13, and 13 years, respectively. The distinct features revealed by the images were described, and the eruption state of impacted permanent teeth was evaluated. The features common to the 3 cases were multiple supernumerary teeth, the presence of Wormian bone, underdevelopment of the maxilla and the maxillary sinus, and clavicular hypoplasia. The eruption of impacted permanent teeth was not observed without proper dental treatment in adult CCD cases, even after long time periods had elapsed. When proper orthodontic force was applied, tooth movement was observed in a manner not significantly different from the general population.

The purpose of this study was to develop an educational app that informs parents of elementary students with correct information on pesticide residue based on their awareness and information needs on pesticide residue. A survey was conducted from 918 parents living in 8 different districts of Korea. The results of the survey indicated that a majority of parents felt uncomfortable with pesticide residue and wanted to have the proper information regarding it. Based on the above results, an app named 'Perfect Conquest of Pesticide Residue' consisting of 5 main menus of 'Pesticide residue, Is it safe?', 'Safe management of pesticide residue', 'Perfect removal of pesticide residue on fruits and vegetables through washing', 'Shopping without anxiety', 'Playground' and their own sub-menus was developed. When the app was applied to 30 parents using smart phones, a majority of them were satisfied with the contents of detailed information and fun activities. Therefore, this app could be utilized as an effective educational tool for the parents of elementary students by allowing them to have proper awareness on pesticide residue. Furthermore, more apps could be developed on other food risk factors to promote safe dietary life.

The data were collected by questionnaire developed for the purpose of this study which has been made through references and student's health record. The results were as follows, 1) As students move up to grade, the number of students with decreased visual acuity had a tendency to increase. In cases with decreased visual acuity below 0.2 in one or both eye, the number of cases was increased in accordance with moving up to grade, especially visual acuity of right eye was more decreased than that of left eye. 2) As to proportion of the group with decreased visual acuity among the total students, among 2250 students, students with decreased visual acuity was 35.6%(800 students). According to school type, in academic school, frequency of students with decreased visual acuity in day school was higher then that in night school. In commercial school, the frequency of students who had decreased visual acuity in night school were higher than that of students in day school. 3) As to variables influencing the decreased visual activity, there was a significant different between groups with normal visual acuity and groups with subnormal in terms of awareness of visual acuity by themself, parent's visual acuity, unbalanced eating habit, distance from television, or books, posture in watching television, posture in reading, awareness of illumination in classroom. 4) As to practice of protective and preventive health behavior for visual acuity care, In group with normal visual acuity. There was good practice such as proper eating habit, proper studying habit, and health habit in its descending order, but proper illumination and regular eye test were practiced poorly. In group with subnormal visual acuity, one of the vest practice in visual acuity care was an effort to prevent eye strain. Other good practice involve tasking regular eye test, maintaining proper studing habit, in its descending order.

This research was performed to evaluate the effects of nutrition education on food waste reduction at school food service. A dietitian conducted nutrition education on environmental protection and proper eating attitude and poor eating habits for 3rd and 5th graders at an elementary school in Seoul. The effectiveness of the education was evaluated by surveying the students before and after the education; 375 responses were analyzed. A questionnaire was designed to compare changes of the students' attitudes and plate waste before and after education. Plate wastes of boiled black rice(p<0.05), potato soup(p<0.05), amaranthus herb salad(p<0.01), and cabbage kimchi(p<0.05) decreased significantly after education. Students' eating attitudes improved significantly(t= -6.22, p<0.01) after nutrition education. Major reasons the students did not eat all foods they were served were large portion sizes (30.59%), low menu preference (29.79%), and tastes (17.82%). The menus with high plate waste rates were cooked vegetable items (35.64%) and soup items (26.6%). After education, students' attitudes on ‘food waste pollutes the Earth(p=0.013)’, ‘food preparation for birthday parties(p<0.01)’, and ‘restaurant selection for eating out (p<0.01)’ changed significantly. After education, plate waste and portion sizes that the students perceived were not negatively correlated. In conclusion, nutrition education on proper eating habits and source reduction is an effective method to reduce food waste generation and to improve students' eating attitudes and awareness on environment.

This study examined mothers' perceptions on nutrition education for elementary school students according to demographical factors. Questionnaires were distributed to the mothers of 511 elementary school students in the Busan area. According to the results, 50% of the respondents felt that the preschool years or the lower elementary grades were proper times to start nutrition education. Furthermore, they preferred school dietitians (55.4%), outside professional dietitians (16.3%), nurse teachers (13.8%), class room teachers (11.7%), and parents (2.8%) as nutrition educators. The mothers who were college and university graduates had significantly (p<0.001) higher scores regarding the necessity of nutrition education for student growth when compared to mothers who were high schools graduates. However, the high school graduates had significantly (p<0.001) higher scores than the college and university graduates with respect to nutrition education for correcting obesity. The order of importance for nutrition education curriculum content was as follows: eating habits, food safety, health and disease, maintaining ideal body weight, food waste and environment, basic food knowledge, and traditional foods. The college and university graduates, and those of 'A' group schools, had significantly (p<0.001) higher importance scores for proper eating habits. Mothers having experience with nutrition education comprised 43.9% of the subjects, and there was a significantly (p<0.05) higher percentage of employed mothers as compared to unemployed. Eighty-six percent of the respondents wanted to receive nutrition education. For more effective learning, they preferred in-person group education rather than correspondence education using e-mails or printed materials from schools.

Primary school is regarded as an important period when many health-related behaviors and life-styles begin to be formed. Acquiring them through school heath education has a strong influence on the health promotion of not only the family but also the community. The objectives of this study were to evaluate current oral health care of elementary schools in Chungnam province and to provide information for further development in elementary school oral health. We performed a questionnaire survey to 280 health teachers and among them, 155 teachers answered. The result of this study were as follows: 1. Sixty five percent of the health teachers had little interest in oral health. Major information sources for teaching oral health were books in 58.1% of the 155 teachers and 83.2% of teachers spent 30 minutes to 1hour per day in oral health care practice for the students. 2. Contents of the oral health education were composed of regular and special curriculums, and an average of education time during a semester was 2.6 hours in 3rd grade, and 1.3 hours in first and second grade. 60.6% of the teachers made the children practice the proper method of tooth brushing during the education time. 3. Major problems in oral health education were insufficient time, lack of equipment and difficulty in teaching method. The educational media were tooth models among 91.0% and OHP among 85.2% of the teachers. The tooth model was usually used in first to fourth grades and OHP in fifth to sixth grades. But 63.9% health teachers need to develop stronger educational methods using multimedia. 4. Meanwhile the most important strategy of oral health in urban schools was health education, that of rural schools was fluoride mouth-rinsing programme. Fluoride mouth-rinsing programmes were performed by 60.0% of the elementary school. Periodic dental examination was performed in all elementary schools. 98.2% of the schools sent the results home through school notification letters, but post-examination management was performed in only 67.1% of them 64.5% of the health teachers do follow-ups on the oral disease of the children after the examination. Only 0.7% of the schools have oral health education plans for the students' parents. Considering these major strategies for elementary school oral health care were health education, practicing proper methods of tooth brushing, periodic dental examinations, and fluoride mouth-rinsing programmes. But health teachers need more time for oral health education, practicing and management, and developing education materials. With regard to the high demand for oral health education and poor follow-up after periodic examination, the oral health education in elementary school should be considered as a formal educational course for more proper management of oral health, including application of major strategies to the children in earlier grades and efforts for increasing recognition and participation of the parents.
