The purpose of this study is to investigate the regional change of dental scaling experience by scaling insurance coverage in July, 2013. The data were used in the "Community Health Survey" of the 2012 and 2014. The results of the study are as follows; 1) The subjective oral health status and brushing of lunch was highest in Gangnam-gu in both 2012 and 2014(p<0.001). 2) Regular dental check-up was high in Gangnam-gu in both 2012 and 2014(p<0.001). 3) The Scaling experience rate increased in all three regions(p<0.001). 4) The socio-demographic characteristics and scaling experience were higher in 2012 and 2014(p<0.001). The scaling experience was higher when there were office workers and spouses(p<0.001). From the policy perspective, it seems necessary to take measures to reduce the gap in scaling experience rate due to differences in income and unequal medical environment.

Objectives: This study was conducted to find scaling patients' oral health belief and satisfaction by applying Comprehensive Dental Hygiene Care (CDHC) process. Methods: From July 1 to September 20, 2020, the data about 182 patients who had scaling in dental clinics and hospitals had been collected and analyzed. For data analysis, SPSS Statistics 22.0 was applied to conduct frequency analysis, chi-square, t-test, One way ANOVA and Pearson's correlation analysis. Results: Regarding oral health behavior, in the CDHC group 92.4% used oral care products (p<0.001), and 67.4% regularly visited dental clinics for oral care (p<0.001). Regarding the oral health belief according to general characteristics, in the CDHC group, persons aged '50-65' scored 2.4 (the highest), and were significantly different from those aged '20-29' as the result of post-hoc analysis (p<0.001). Regarding the oral health belief of the CDHC group according to oral health behavior, the scaling cycle '3 months' scored the highest (p<0.05). The patients' satisfaction had high correlations with benefit (p<0.01) and Importance (p<0.05) as the sub factors of the oral health belief of the CDHC group. Conclusions: CDHC positively influenced scaling patients' oral health belief and satisfaction. Therefore, it is necessary to expand CDHC, as the medium to improve oral health belief and satisfaction, to clinical settings.

The purpose of this study is to investigate the convergence effects of the experience of adult preventive care on the treatment satisfaction and the dental fear, and the survey was conducted from January to April 2017 for 292 adults of aged 20 years or older living in the metropolitan area. The collected data were subjected to $x^2-test$, t-test and multiple regression analysis using SPSS 22.0 program. Fluoride application was the most prevalent experience of adult preventive treatment, and the satisfaction level of the treatment was high in case of fluoride application was experienced. On the other hand, dental fear was lower if preventive scaling was experienced. As a result of multiple regression analysis, variables affecting patient satisfaction were experience of fluoride application, and the variables affecting dental fear level were oral health condition and preventive scaling experience. The result of this study was confirmed that the satisfaction level of treatment was increased and the dental fear was lowered. Therefore, improvement of oral health promotion can be expected by recognizing of the importance of preventive treatment and providing of the dental preventive service through oral health education.

This study was conducted to reveal the relationship between the oral health status and their Knowledges about the oral health of the freshman of colleges in Taegu city. The evaluation for the oral health status through the oral examinations and their analysis of their knowledges on the periodontal disease were done on 216 males and 205 females from 1st to 30th April, 1993. The obtained results were as follows: The oral health status of 421 subject showed that 35.7% was good, 59.1% fair, and 6.2% poor, respectively. In case of the oral health status of females, 41.9% was good and 4.4% poor, and then in males 27.8% was good, 7.8% poor. The oral health status of the females was better than that of the males(p=0.006). The 52.1% among the good oral health status group answered that the dental plaque is the bacterial membrane causing dental disease, and the 23.1% among the poor oral health status group answered same as the above. The 91.8% among the good oral health status group answered that the periodontal diseases can be prevented, and the same answer came out from 15.4% of the poor group. It was found that the better oral health status group had the better knowledges about periodontal disease(p=0.001). For the question about their experiences in scaling the 30.1% of good oral health status group and the 23.1% of poor group answered that scaling is very helpful to periodontal health(p=0.001). About the experience of the education for tooth brushing, the 53.2% of good oral health status group and the 7.6% of poor group had the experiences to receive the education for tooth brushing(p=0.001). About the frequency and the time of tooth brushing, the 53.4% of good oral health status group brushed their teeth more then 3 times a day and 41.8% of good group brushed their teeth after every meal(p=0.001). The result of multiple regression analysis according to the simplified oral health index indicated that the variable having an effect on the oral health status was the tooth brushing frequency, knowledge of periodontal disease prevention, experience in education of tooth brushing and time of tooth brushing(p=0.001).

Recently, many studies using reinforcement learning-based autoscaling have been performed to make autoscaling policies that are adaptive to changes in the environment and meet specific purposes. However, training the reinforcement learning-based Horizontal Pod Autoscaler(HPA) policy in a real environment requires a lot of money and time. And it is not practical to retrain the reinforcement learning-based HPA policy from scratch every time in a real environment. In this paper, we implement a reinforcement learning-based HPA in Kubernetes, and propose a transfer leanring technique using a queuing model-based simulation to accelerate the training of a reinforcement learning-based HPA policy. Pre-training using simulation enabled training the policy through simulation experience without consuming time and resources in the real environment, and by using the transfer learning technique, the cost was reduced by about 42.6% compared to the case without transfer learning technique.

Objectives: The purpose of the study is to investigate the influencing factors of community scaling rate using community health survey data. Methods: The data were extracted from 2013 Community Health Survey, Ministry of education, Korea Dental Association, Statistics Korea, Health Insurance Review and Assessment Service, and Ministry of the Interior. The resource factors of independent variables were analysed by Geographical Information System(GIS) using Map Wizard for Excel 17.0. The data were analyzed by descriptive analysis, pearson correlation and multiple linear regression analysis(p<0.05). Results: Seocho-gu in Seoul had the highest annual scaling rate(55.5%) and Goheung-gun had the lowest rate(11%) showing 44.5 percent gap. The influencing factors of scaling included the number of dental hygienists(r=0.316), dentists(r=0.332), dental hospitals(r=0.470), high school graduation rate(r=0.757) and equivalence scales household income(r=0.764)(p<0.05). Multiple linear regression analysis showed that community scaling rate was closely associated with community education level and monthly income(p<0.05). Conclusions: Community scaling rate was closely related to the community education and income level. It is necessary to provide the equal distribution of the oral health service to the community society.

In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.

Workers' oral health is important to guarantee workers' right of health and increase productivity. The aim of this study was to investigate recognition and satisfaction of national oral examination for workers in Incheon and Daejeon. Three hundred seventy-nine workers who were selected by convenience cluster sampling answered the questionnaire about experience, recognition and satisfaction of national health examination and oral examination by self recording type. A total of 76.0 percent of the subjects had national health examination, and 51.7% had national oral examination. A total of 64.9 percent had experienced notice about national health examination from the company, and 28.2% about national oral examination. The subjects had high positive score about intention of treatment, dental scaling, and change of toothbrushing method depending on oral examination, need of national health and oral examination, and usefulness to one's health through national health and oral examination. Office workers, regular workers, and the workers with monthly income more than 2 million won had more notice about national health and oral examination compared with sales and production workers, contract workers and the workers with monthly income less than 2 million won. We suggest institutional management of the notice about national oral examination be needed, especially for economically poor, or contract workers to increase the ratio to have national oral examination.
