Objectives : The oral care during early childhood plays an important role to maintain sound oral health during adulthood. As the number of children's using child care facilities is on the rise recently, the children's oral health awareness and behavior of the educators at nurseries and kindergartens are to be examined. Methods : A self-recording survey was conducted on 194 educators at the nurseries and kindergartens in Chungnam region. Results : The most frequently given snack was milk, 91.8 percent of the facilities had children brush their teeth, 63.4 percent made them apply fluoride and 56.2 percent kept children's toothbrushes in an ultraviolet rays sterilizer. There was a meaningful difference in the awareness of the necessity to educate children about oral health according to the offer of the opportunity to apply fluoride (p<0.05). A meaningful difference was found in the recognition of the necessity to educate children according to their grade (p<0.05) and to train teachers themselves (p<0.05). The most desirable persons in charge of oral health education were dentists in health centers (46.9%) in order. The more experience in teaching they have had (p<0.05), when they're married (50.5%) (p<0.05) and when they're not homeroom teachers (52.6 percent), the more regular checkups they have had (p<0.05). As for the importance of oral health and the results of regular checkups, those who had answered 'very important'(42.4%) showed higher rate of regular checkup (p<0.05) than those who had answered 'important'(23.9%). When teachers have the experience to get trained about oral care (96.3%), the practice frequency of brushing teeth was proved to become higher (p<0.05). Conclusions : The educators for children should recognize the importance of oral health education, educate children to practice oral health care, and the environment and systematic foundation should be established which the educators manage effectively.

This purpose of this study was to provide the basic data for preventing dental caries, and maintaining and enhancing oral health. The subject of this study through the survey of the recognition of oral health, a questionnaire survey was conducted for 545 male and female students who were in the 4th, 5th, 6th grade of elementary school in Ulsan city. Statistical analysis was conducted using the SPSS 11.5 with t-test, ANOVA and correlation. The obtained results were as follows 1. Oral health knowledge false for Dental floss silk, Fluoride and very low. 2. The students who were in the 4th, 5th, 6th grade of elementary school is Oral health knowledge, behavior and tooth brushing frequency 4th 5th grade higher than 6th grade(p = 0.000, p,0.005). 3. Oral health knowledge is higher behavior high date (p = 0.001), and Oral health behavior is higher many tooth brushing frequency (p = 0.000).

화학센서는 분석물질과 감응물질간의 화학적 반응을 통해 분석물질을 선택적으로 인지하고 이를 통하여 특정물질을 실시간으로 분석할 수 있는 기술이다. 최근 화학센서로 색소를 이용하여 음이온을 진단/감응하는 기술이 각광 받고 있으며, 더불어 음이온을 선택적으로 인지함에 있어 검출하고자 하는 특정 음이온에 대한 민감도를 높이기 위한 노력이 계속되고 있다. 감응물질로 이용되는 색소는 주로 분자 내 전하 이동형 색소(intramolecular charge transfer dye)로 주위 환경 변화에 민감하게 반응하며, 자극에 따른 변화를 흡수와 발광, 굴절률의 변화 등으로 나타낸다. 또한 다양한 음이온 중 분석물질로써 연구 가치가 큰 음이온에는 플루오린화물(fluoride)이 있다. 이는 플루오린화물이 치아 보호와 골다공증에 중요한 역할을 하는 순기능을 가지는 반면 고농도 상태에서는 불소증(fluorosis)을 비롯한 악영향을 잠재적으로 가지기 때문에 그 양을 인지하는 것이 중요하게 여겨지기 때문이다. 따라서 본 연구에서는 2-(3,5,5-trimethylcyclohex-2-enylidene)-malononitirle과 indole-3-carboxaldehyde를 통하여 분자 내 전하 이동형 색소를 합성하고, $^1H$ NMR, GC-mas, EA로 합성된 색소의 물성을 분석하였다. 우선 반응물인 2-(3,5,5-trimethylcyclohex-2-enylidene)-malononitirle을 합성하기 위해 dimethylfor mamide(DMF) 용매 하에서 isophorone과 malononitrile을 12시간 반응시키고, 얻어진 결과물을 정제한다. 이후 indole-3-carboxaldehyde와 10시간 환류시켜 색소를 얻는다. 합성된 색소는 F 이온 검출에 이용되며, UV-vis 분광법을 이용하여 분석물질에 따른 흡수 정도와 강도 변화를 살펴본다. 연구의 최종적인 목적은 비단 진단/감응 색소의 합성이 아니라 나노 섬유 소재와 색소의 접합을 통해 진단/감응형 나노 섬유를 개발하는 것으로 이를 위해 전기방사법이 이용된다.

Objectives : The purpose of this study was to obtain the information for the improvement of the support in oder to expand the adjusted water fluoridation program to Myeong-dong water treatment plant in Gimhae city, Korea. Methods : Questionnaires were distributed to the parents of elementary schoolchildren and their responses were collected. All collected data were analyzed using the SPSS program. Results : The percentage of respondents using the tap water was 47.0% for drinking and 54.4% for cooking, respectively. The percentage of respondents using the water purified the tap water with the home water purifier was 45.1% for drinking and 36.2% for cooking, respectively. Respondents who knew the adjusted water fluoridation program was 48.3%. Respondents who knew the implementation of the adjusted water fluoridation program at the moment in Gimhae was 27.0%. 90.2% of residents agreed on the expansion of the adjusted water fluoridation program to Myeong-dong water treatment plant, Significant variables in the approval rates of the adjusted water fluoridation program were age, residence period, occupation, recognition of the program. Conclusions : It is desirable to expand the adjusted water fluoridation program to Myeong-dong water treatment plant in Gimhae as the percentage of respondents who agreed on the introduction of the program was high.

As a result of having surveyed and analyzed recognition and requirement of dental hygienists for Academic Credit Bank System, the recognition on Academic Credit Bank System accounted for 70.8%, and in terms of information media recognized, surrounding people were the highest with 52.4%. And, in case of the response as saying of being willing to participate, an opportunity of acquiring a bachelor's degree accounted for 24.0%, and in case of the response as saying of being unwilling to participate, the lack of time that will take part in education activity accounted for 13.7%, thereby having been surveyed to be the most preferential choice, respectively. The importance by sphere in course programs was indicated to be the sphere of preventive dental treatment with 3.61, the sphere of dental management with 3.38, the sphere of oral health education with 3.09, the sphere of medical-treatment coordination with 2.82, and the sphere of community dental health with 2.11 in order. The importance by field of sphere in course programs was indicated to be high in the field of oral health education by subject with 2.30 for the field of sphere in oral health education, in the field of plaque control and oral prophylaxis with 3.53 for the field of sphere in preventive dental treatment, in the field of management of the fluoride mouth-rinsing programme with 2.86 for the field of sphere in community dental health, in the field of counselling with 3.24 for the field of sphere in dental management, and in the field of medical-treatment assistance with 1.53 for the field of sphere in medical-treatment coordination.

The aim of this study was to examine the effectiveness of oral health promotion program in a group of 9~18-year-old children and adolescents living in four orphanages in Dong-gu, Daejeon. The program was based on oral disease prevention program including oral health education, fluoride application and scaling every six months. Oral health status of total 109 orphans was examined by one dentists who were trained in 2010 Korean National Oral Health Survey. Dental caries index, community periodontal index and modified patient hygiene performance index (M-PHP) were checked using dental unit chair. Child oral health impact profile (COHIP) and subjective oral health recognition survey were carried out. Compared with data of 2010 national sample, the mean of decayed, missing and filled teeth showed no difference between the subjects and test values, but the means of decayed teeth, decayed surface, toothbrushing frequency of the subjects showed to become worse with advancing years in spite of oral health promotion program. COHIP, subjective oral health status showed lower than test values, too. In M-PHP and Calculus index, the subjects showed better by periodic oral health education and scaling. We suggest that oral health promotion program for orphans include oral disease treatment program as well as preventive program to improve oral health of orphans efficiently. And, oral health promotion program has to be connected with psychological support for improving quality of life of orphans.
