Objectives : The purpose of this study was identified about oral health status and oral health needs of elderly. Moreover this study would be based further research of development of oral health in elderly. Methods : This study was undertaken to determine the oral health status and the need of oral management of over 65years elderly who were with dental prosthesis in elderly welfare center and Kyung Ro Dong in Kyung Bok and Kyung Nam. The results were as follows. Results : The sample was 200 participants. The demographical characteristic were that 74.0% of participant was female, 29.0% of participant was 75~79 years old, 42.5% of participant was under elementary, and 45.5% of participant was living alone. 43.7% of participant was pain from muscle-skeletal disease, 37.1% of participant was cardiac-vascular disease, and 31.1% of participant was ophthalmic disease. In oral health status, 54.5% of participant was partly artificial tooth and 45% of participant was whole artificial tooth. 78.0% of participant used under 10 years with partly artificial tooth and only 27.4% were satisfaction with artificial tooth. 83.5% of participant used under 10 years with whole artificial tooth and only 26.4% were satisfaction with artificial tooth. In the oral health status of partly artificial tooth, the average of toothbrush was 2 times, 42.2%. The majority method of toothbrush was 'their own freely' 55.0%. The time of toothbrush was 'after meal' 81.8%. The study result showed that majority participant didn't experience of tongue brush, regular examination, scaling, and oral health education. In the need of oral management with the whole artificial tooth, the participant who used longer artificial tooth was significantly higher about artificial irrigation and the method of management(p<.05). The need of participant who answered 'don't gum massage', was higher of xerostomia treatment(p<.01) and halitosis treatment(p<.05). In the need of oral management with the partly artificial tooth, the participant who used longer artificial tooth was significantly higher about regular examination(p<.01), oral cavity massage(p<.05), scaling(p<.05), dental caries treatment(p<.01). The need of participant who answered 'don't satisfaction with artificial tooth' was higher of regular examination and scaling(p<.05). Conclusions : Oral management needs of elderly who kept artificial tooth or denture required were regular dental examination, xerostomia management, management of artificial tooth and irrigation, and management of bad breath. This results meaned the oral health intervention program for elderly was developed regularly.

Objectives ： Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by abnormalities of social functioning, communication and behavior. The association of the 7q21-34 region with ASD has been reported. The DLX6 gene, which is located at the 7q22 region, is one of the positional and functional candidate genes for ASD. We found that there is no association between DLX6 polymorphisms and ASD in the Korean male population. Methods ： We selected three single nucleotide polymorphisms (SNPs) that might be implicated in the change of the DLX6 gene expression. The genomic DNA was collected from the venous blood of 147 male controls and 179 male patients with ASD. The genotypes of the selected SNPs were determined using the Illumina GoldenGate assay, and the statistical analyses were performed using HapAnalyzer software and SAS Enterprise. Results ： We found no association of the three SNPs in the DLX6 gene with ASD in the Korean male population. Conclusion ： Our study suggests that the three SNPs in the DLX6 gene are not associated with ASD, and we need to analyze the previously reported regions for their associations with ASD.

The purpose of the study was to find out the usefulness of teachers' recommendation in selecting gifted students. For the study 87 teachers teaching 4th grade students from 20 elementary schools in the area of Incheon, 103 gifted students who were recommended by teacher, and 65 gifted students who were not recommended by teacher participated. To measure their cognitive ability, Raven intelligence test, creative problem solving test in science, and TTCT were used. In addition, learning methods, motives for achievement, faith in academic ability, problem solving tendency, and assignment preferences were assessed to find out their affective qualities. The results were as follows. First, the students who were recommended by teachers were highly advanced in both cognitive and affective aspects related to giftedness compared to non recommended students. Second, there were no significant differences both in the cognitive and affective aspects among the students recommended by teachers whether they passed the second step(test for giftedness) and the third step(test for academic aptitude) or not. Third, the discriminant analysis showed $70{\sim}80$ percent accuracy on teacher recommendation in identifying gifted students. The implication of the study related to teacher recommendation and future direction on identification of gifted students were discussed in depth.

Chemistry is the subject which includes properties, change, and composition of matter. Chemistry has the system which explains observable properties and change with microscopic level, it explains them using scientific theory and laws. In the national-level curriculum, the properties and changes of matter are continuously dealt with from elementary school to high school, and the curriculum are organized so that students could strengthen their understanding about matter. In other words, understanding of the properties and changes of matter is the base to explain everyday life with the view of chemistry, and these two are classified as domains of chemistry in the 2015 revised science curriculum. In this study, we confirmed students' understanding about properties of matter and change of matter, through the analysis about results of the National Assessment of Educational Achievement (NAEA). For that purpose, this study analyzed the 12 items about properties of matter, and 19 items about change of matter, which were used in the NAEA from 2015 to 2019. According to the results of classifying and analyzing questions according to the core concept, the understanding about the two domains significantly changed between the proficient achievement-level students and basic achievement-level students. Depending on the achievement-level, there was a difference in explaining the phenomenon by using the perspective of particles, and by associating scientific concepts and models, or there was a difference in understanding the inquiry related to these two domains. Based on this analysis, this study discussed some implications to be improved on teaching-learning for 'properties of matter', and 'change of matter'.

Mixed reality(MR) technology combines the advantages of virtual reality(VR) and augmented reality(AR) technology, allowing MR users to interact with virtual objects against the background of the real world. In addition, since virtual objects interact with the real world, users can experience a higher immersion. This study proposes electric circuit practical training content using Meta Quest Pro to produce immersive MR content based on reality. To this end, first, the development process for producing MR content by linking Meta Quest Pro equipment with the Unity 3D engine is organized. Then, based on the traditional electric circuit practical training method used in elementary school science classes, virtual electric circuit practical training content with the same training method and operation process is produced based on MR. Finally, survey experiments are conducted to analyze the presence and experience of the MR-based educational environment provided using the produced content. Through this, the usability of the proposed practical training content is evaluated and future research directions are suggested.

This study was conducted to provide the basic data for the health management of the primary school, by finding and analyzing the factors affecting the degrees of atopic dermatitis symptom's severeness. The subjects of our study were collected 273 pupils mothers, whose children are undergoing through the atopic symptoms. The investigation process took the entire month of the November in 2006. The result of the older the pupils, the severer their symptoms(p<0.05). The longer the period(p<0.01), the more widely spread over the body, and the severer the symptoms(p<0.01). In the dietary habit, the more meat they eat, the severer the symptom(p<0.05). and in relation to the eating the food outside home, the more frequently they eat the fast-food, the severer the symptom. In the multiple logistic regression analysis, using the degrees of atopic dermatitis symptom's severeness as the dependent variables. it is discovered that the longer infection period they have and the more frequently they have the fast-food, the severer the symptom of the atopic dermatitis. The parent's love for the child, the monthly cost for the management of the infection, and the parent's feeling toward the child, can have a greate influence on the physical health, the feelings and the relation with the friends of the infected child, when the child shows the symptoms of scratching his skin. The conclusions of When all the results above are put together, the dietary habit of eating the meals mostly prepared with the meat should be corrected, and the education to form the pupil's right dietary habit, such as, putting the limit on the fast-food, must be made, in order to prevent the symptom of the atopic dermatitis from getting worse. And by the recognizing the atopic dermatitis as the family health problem, the comprehensive family health management, including the mother should be made.
