I got the following conclusion that analyzes the dental health recognition, attitude and the action of the students who major in health section executing questionnaire about dental health behaviors from March 3 through 26 with health-related university students in some area in order to arrange the fundamental data that manage their mouth health rationally by using the investigation and comparison by sex and department in dental health teaching. The results obtained were as follows : 1. A large number of students recognized dental health as an important problem, but they believed that the level of their knowledges on dental health was not so high and female students were more negative than male students with regards to their own dental health condition. 2. 49.8% of the students know about tap water fluoridation program control business and 60.7% agreed and boy's approval rate was higher than girl's. But 42.2% of the not-related buccal department's students have a reservation about tap water fluoridation program control business. 3. Average brushing number of the boy is 51.0% 2 times a day according to sex, A girl appeared highest by 48.3% 3 times a day and there was statistically significantly different according to (pE0.01). there wasn't statistically significantly different according to department. Also, the period of the brushing was the most right after a breakfast, in the order of before sleep and after dinner. 4. Whether they go to the dentist's or not, 90.8% of them say 'yes', the result showed statistically significant difference according to sex (pE0.01), but It didn't show statistically significant difference according to department. Also, the purpose for visiting the dentist's office lately was the most caries treatment. and there was statistically significantly different according to sex (pE0.01), but there was not statistically significantly different according to department. 5. Oral health education-related subject approval's rate when the education course open is 65.0% there was statistically significantly different according to department (pE0.01). Also when oral health education-related subject as the liberal arts open' the rate of taking a course application showed 50.2% high appear. there was statistically significantly different according to department(pE0.01).

The purpose of this paper is to identify woodblocks which were engraved in the providences in the mid Chosun dynasty, especially ones engraved under the auspices of Yu Heui-chun(柳希春), but not listed in $\boxDr$Kosachwalyo 攷事撮要$\boxUl$. This could be done by the analyzing $\boxDr$The Diary of Miam 眉巖日記$\boxUl$ written by Yu Heui-chun. It is a book which recorded daily life of eminent scholar and official covering political, social and cultural aspects, books and family matters. There were two categories of books published under the auspices of Yu Heui-chun. One is the books written by his grandfather in law, Choi Bu(崔溥), which were $\boxDr$Keumnamjip 錦南集$\boxUl$ collective works of Choi Bu, and $\boxDr$Pyohaerog 漂海錄$\boxUl$, essays on travelling across China. The other is the books for children, $\boxDr$Sinjeung Yuhap 新增類合$\boxUl$ for teaching characters and $\boxDr$Sog Mong-gu 續蒙求$\boxUl$ for moral education. These woodblocks have to enlisted in the woodblock catalogs. The analysis shows that most of these woodblocks by Yu Heui-chun were not recorded in either of two $\boxDr$Kosachwalyo 攷事撮要$\boxUl$ editions published in 1575 and 1585. In this respect, $\boxDr$The Diary of Miam$\boxUl$ proved itself to be of great significance in terms of bibliography studies.

The purpose of this study was to design a web-based project learning that is suitable for teaching concepts by studying the motion of the Moon for middle school students and to investigate the effects of the lesson applying designed learning. Designed learning was conducted with 48 ninth graders, who were individually interviewed; 5 males and females students out of the total. The types and factors of the unscientific concepts on the motion of the Moon were analyzed by the pre-test using interviews and questionnaires being evaluated to the degree of concept level that was developed in this study. After the pre-test students were instructed to do the web-based project learning where they could observe the motion of the moon for a month and discuss the results from the observation. After the web-based project learning, the effect of learning was examined by applying the post-test to the students and by analyzing the comparison of the pre-test and the post-test. The web-based project learning was effective for the conceptual change of the motion of the Moon (p<.001). According to the post-test, it positively affected the students and improved their integrated processing skills. Specifically, it had effects on conducting experiments (p<.001), controlling variables and defining operations (p<.05) in integrated processing skills.

Problem-based Learning (PBL) has been known as an effective strategy for dealing with various aspects of education such as the enhancement of students' motivation, interest in subjects, academic achievement, and cooperative abilities. However, PBL has not been widely implemented in secondary schools. The purpose of this study is to investigate secondary school teachers' perception of problem-based learning and their way of applying it. Data was collected through semi-structured interviews with nine secondary school teachers. Five of them had experience in implementing PBL, while four of them had interest in using PBL but had not yet had the experience. Different concepts were extracted and categorized. Nvivo 2.0 was used for analysis. The results were as follows: Changes in student attitude toward class, improvement on cooperation with others, self-regulated learning skills, and satisfaction from students' positive comments on PBL enabled teachers to become more enthusiastic and positive toward PBL. The stress of developing proper problems and the enormous amounts of time and efforts required in using PBL were shown as barriers for teachers in implementing PBL. However, some negative perspectives about PBL changed into positive after teachers experience PBL. By examining each teacher's way of implementing PBL, several teaching strategies suitable to their school systems were suggested.

Based on social cognitive theory, self-efficacy in the context of learning has been steadily emphasized as an indicator of students' motivation and performance. The premise for developing such an instrument was that a specific measure of Physics self-efficacy was deemed to be an important predictor of the change processes necessary to improve students' physics understanding. In this study we described the process of developing and validating an instrument to measure students' beliefs in their abilities to perform essential tasks in physics and then investigated high school students' self-efficacy about physics learning and performance. Validity and reliability of PSEI were tested using various statistical techniques including the Cronbach alpha coefficient, exploratory factor analysis. The result of factor analysis supported the contention that the Physics Self-Efficacy Inventory (PSEI) was a multidimensional construct consisting of at least four dimensions: understanding and application of Physics concepts, achievement motivation, confidence for physics laboratory, confidence for Mathematics. The result showed that Kroean high schools students have low Physics self-efficacy for the all four dimensions. Therefore, researchers should focus on development of students' Physics self-efficacy. In addition, the instrument may lead to further understanding of student behavior, which in turn can facilitate the development of strategies that may increase students' aspiration to understand and study Physics. More specifically, by using the PSEI as a pre- and post-test indicator, instructors can gain insight into whether students' confidence levels increase as they engage in learning Physics, and, in addition, what type of teaching strategies are most effective in building deeper understanding of Physics concepts.where they freely exchanged opinions and feedback for constructing better collective ideas.

An image is a comprehensive result that you have experienced about an object and means the image that you have on the surface of your consciousness. The image of the subject has an important influence on learning the subject. The image analysis of the subjects that the learners have will be good data to decide the direction of teaching and learning. The purpose of this study is to develop and apply measurement tools for physics image and discuss its educational implications. The research method is to develop the measurement tools for the physics image by semantic analysis method and apply it to the secondary pre-service physics teacher. The subjects of the study were 39 first graders, 31 second graders, 37 third graders, and 38 fourth graders at the University of Education, a total of 145 students, 82 of whom were male and 63 were female. The study results show that the image measurement tools for physics consisted of 25 items from five elements: 'interest,' 'feeling,' 'scope,' 'evaluation,' and 'viewpoint.' There were statistically significant differences between the male and female students in applying the measurement tools developed for the physics image of secondary pre-service physics teachers. Male students showed significantly higher statistical significance than female students in the 'interest' and 'feeling' elements of measurement tools for the physics image. In the 'scope' element of measurement tools for the physics image the second grade was statistically higher than the fourth grade. Finally, we discussed educational implications for image analysis of physics and the usefulness of using measurement tools in physics image.

An increasing number of students are giving up on learning mathematics at all grade levels, including elementary school. The study in this paper considers seven non-cognitive student characteristics to identify which are strongly correlated with giving up on mathematics at the elementary school level. Data were collected with a survey on the non-cognitive domain of mathematics learning that was developed by the Korea Foundation for the Advancement of Science and Creativity in 2015. The data were collected from 3,636 elementary school students in Korea, and we analyzed the data using the statistical computing program R. Of the seven components, efficacy and interest have a strong correlation with students' tendency to profess that they have given up trying to learn mathematics. The findings of the study shed light on which non-cognitive domain areas mathematics teachers need to pay more attention to in order to make their teaching effective. This study further investigated the correlation between responses to each of the 24 survey items and students' claim that they have given up on mathematics. Using the 8 items with the highest correlations, we have developed a shorter, 8-item version of the survey, which will be useful for similar future studies.

This study was made to analyze the condition and the needs of nutrition education considering the different stage of nutrition education recognized by the dietitian in industrial area. 165 female dietitian were surveyed by questionnaire and they were divided into 4 groups according to the different recognition stages of nutrition education: Pre-contemplation(PC) 4.8%, Contemplation(CO) 46.7%, Preparation(PR) 22.4%, Action & Maintenance phase(AM) 26.1%. For statistical analysis, SAS(Ver.8.1. for Window) was used to find out the distribution related with nutrition education and to calculate the scores of mean and standard deviation. General characteristics of the subjects are about 20 years old(71.5%), single(69.7%), careers over 5 years(40%) and university graduates(73.9%). The number of meals(p<0.05) and the employment status(p<0.05) were significantly different according to the recognized stage of nutrition education. The practice of nutrition education was different depending on the dietitian in the industry. Many of the factory dietitian were in pre-contemplation stage(87.5%), however, those in the office and service area were more in Action & Maintenance stage(27.9%). In the industrial area, just 26.1% of dietitian operated the nutrition education and most did not due to the work overload and insufficient support of staff(73.3%). The frequency for the most effective nutrition education was once a month(61.2%). The contents for desirable nutrition education were in the order of 'eating habits'(36.1%), 'relation with the daily life'(23.5%), 'food hygiene' (21.7%), 'nutrition knowledge'(9.7%), and 'disease prevention'(9%). In operating nutrition education, dietitian had concerns about 'insufficient support of staff', 'shortage of teaching materials' and 'lack of time'. And, the dietitian who were with lower recognition stage of nutrition education(P<0.05) concerned more about the insufficient educational contents. In conclusion, dietitian in the industry highly recognized the need of nutrition education, but it was so difficult to practice. For more programs and various materials should be developed, and the staff's perception, the view of dietitian and the meal service should be changed, too. For the health improvement of industrial workers, it would be necessary to proclaim the importance of nutrition education nationwide.

This study aimed to investigate how the current elementary school teachers think about nutrition education, how they are teaching, and what kind of problems have occurred. And this study was made to provide basic materials to be used for the effective nutrition education in the elementary school. The survey was done on 60 elementary school teachers and 570 elementary school students of the 5th and 6th grade in Gyeonggi Province by questionnaire and analyzed for the perception of nutrition education, current status of nutrition education, nutrition knowledge and cooking knowledge. The average scores of nutrition knowledge were 2.72 for male and 3.75 for female students out of full score of 5. The fifth grade students learned more nutrition education than the sixth grade ones in accordance with the different curricula. Nutrition education was taught as apart of other subjects(87%) and mainly done by lectures. For most of the students, information source of the nutrition education was the meal service(47.4%) and the most common one was the Internet that 38.1 % of the teachers used. Most of the students responded that nutrition education was necessary in the curriculum of elementary school for proper growth(36.2%), intelligence(25.9%), health(21.5%), and dieting(16.4%). The perception for the suitable teacher was in the order of nutrition specialist and dietician. And the right time of the related class was in the order of spare time everyday, a special activity time, and the meal service time. The important contents of nutrition education were in the order of proper eating habits, growth & nutrition, food hygiene and diseases. Nutrition problems of the elementary students were in the order of unbalanced diet, too much ingestion of processed and instant foods, lack of table manners, and child fatness and weakness. 80.0% of the teachers supported the early nutrition education and demanded it should begin when children are in kindergarten. The analysis showed that nutrition education should be taught by parents(29.4%), teachers(29.2%), and nutritionists(25.9%) and that family and school should cooperate closely. Main responses of the teachers to the children's problems were that they had too much instant food, did not eat in a variety, and had no manners in eating. Ironically, they thought malnutrition, fainting and growth stunt were not important nutrition related problems.
