This study is to develop an oral healthcare program for students with intellectual disabilities, who were in high-school grades in Special School C located in North Chungcheong Province, and to examine its effect after applying the program. The program effect was the index of oral environment care ability and the score of dental caries risk per each session. In addition, images were taken for phase-contrast microscopy. The PHP index before and after the oral healthcare program and the risk of dental caries decreased but showed no significant difference. An observation on phase-contrast microscopy revealed that the number of cocci decreased at the third session compared to that in the first session, and almost no bacillus was observed. The oral healthcare program, would be able to improve the oral environment care ability of students with intellectual disabilities and lower the risk of dental caries.

Objectives: This study analyzes factors related to English communication skills in the dental health services of clinical dental hygienists who provide dental medical services to foreigners. Methods: Surveys were conducted to measure students' English communication skills. Participants comprised 195 clinical dental hygienists working at dental English study cafes or who provided dental medical services to foreigners. After analyzing the differences in English communication skills, hierarchical multiple regression analysis was performed on the factors related to English communication skills. Results: English communication skill of dental hygienists was 1.96 points out of 5 points. The factors related to the English communication skill of the clinical dental hygienists were foreign patient care, language training experience, overseas living experience, and certified English proficiency. The adjusted explanatory power of this model was 53.0%. Conclusions: Dental hygienists in charge of foreign patients have experience in language training and overseas residence, have a language qualification certificate, and have higher English communication skills. It is necessary to develop English language learning programs based on metaverse to develop the English communication skills of dental hygienists who provide dental health services to foreign patients and to operate a creative educational environment to increase interest in learning English.

Objectives : The purpose of this study was to examine actual conditions of smoking and alcohol drinking behaviors among high school students, so that it could recognize possible harmful effects of smoking on oral health and could give positive motivations for students to quit smoking and drinking. Methods : This research was based on self-filling survey which 1,385 high school students in metropolitan area in Korea from September 5 to October 28, 2011. Surveyed data were analyzed by descriptive statistics, ${\chi}^2$-test and logistic analysis using SPSS WIN 12.0 program and its signification level was 0.05. Results : 1. As for smoking rate and drinking rate, boy students accounted for 11.6% and 25.4%, thereby having been higher than girl students(p<.001). It was the highest in over 180 cm(16.0%, 35.0%, p<.001) for height, in 60-under 70 kg for weight(13.4%, 23.5%, p<.001), and in a case of profession for mother's job(13.8%, 28.4%, p<.005). 2. The perceived oral symptoms had relationship with the less than 10 cigarettes of smoke (OR=2.41; 95% CI:1.31-4.41), more than 11 cigarettes of smoke (OR=3.16; 95% CI:1.42-7.00) and more than 1 bottle of alcohol (OR=1.75; 95% CI:1.00-3.06). Conclusions : This result implies that adolescents' smoking and drinking have correlation with oral health status, which makes uncomfortable sense felt given chewing along with the pain in teeth and gum. Based on the above findings, a school or community needs to reinforce education for preventing smoking and drinking and to offer environment available for practicing anti-smoking and anti-drinking plan, in order to reduce adolescents' smoking and drinking.

Objectives: This research is to provide the basic data for the improvement on oral health by examining the relationship between the dental fear and the dental service utilization, and to discuss a strategy for dental health in order to lower the level of dental fear. Methods: Data were collected by conducting a structured survey of 1,607 people between the age of 13 and 70 who have experiences in visiting a dental institution. Both univariate and multivariate analyses were employed to analyze the relationship between the number of times dental service and dental fears. Results: The average level of dental fear the respondents reported was $52.16{\pm}15.71$ and 31.5% of the response was at the level of high dental fear. A strong physiologic response during the dental treatment was muscle tension and the stimulations that strongly arouse the dental fear were the anaesthetic needle and the sound of drill. A result of analysis on the relationship between the dental fear and the dental service utilization shows that as the level of dental fear became higher, the number of times for the dental service utilization for the last year had reduced. Also when a patient has an experience of putting off or canceling an appointment due to dental fear and as a physiologic response during the dental treatment became stronger, the result shows a tendency that the number of times for the dental service utilization for the last year had reduced. Conclusions: It has been observed that dental fear is one of the main barrier to use dental service. Therefore, a physio-psychological factor like the dental fear should be included in the task of promotion of dental health, and in analyzing the dental service utilization behavior. A discussion about how to lower dental fear was made with respect to oral health promotion. At individual level, improvement of communication skill by dental service providers should be made with rearrangement of clinic environment into more cozy one.

Objective: The purpose of the study is to investigate the curriculum development and operation based on national competency standard (NCS). Methods: The duty of the dental hygienist was analyzed based on DACUM by ten experts in January, 2011. The duty model of the dental hygienist was inspected after duty analysis. The subjects of choice were preventive dentistry and practice. The satisfaction with the subjects were carried out from March to June, 2015. Results: The duty analysis of dental hygienist by DACUM produced preventive dental treatment(11 tasks), oral health education(3 tasks), comprehensive dental hygiene treatment(6 tasks) and 12 categories(156 tasks). Preventive dental treatment was divided into preventive dentistry and practice, oral health education was changed into oral health education and practice, and comprehensive dental hygiene treatment was replace by comprehensive dental hygiene and practice. The contents of preventive dentistry and practice included outline, learning objective, related knowledge and self evaluation. Professional evaluation required mutual experience and evaluation of the students. The mutual evaluation of the students was $4.61{\pm}0.506$(dental plaque control) and $1.80{\pm}0.316$(tooth brushing). The professional evaluation was $1.73{\pm}0.274$(dental plaque control) and $1.60{\pm}0.322$(tooth brushing)(p<0.01). The satisfaction with preventive dentistry and practice was $4.61{\pm}0.506$(improvement in practical work ability), $4.58{\pm}0.511$(knowledge improvement) and $4.55{\pm}0.572$(NCS educational environment) in order. Conclusions: The operation of NCS curriculum is considered to improve practical work ability and to solve skill mismatch between dental industries and educational training institutions.

This study is a review of research articles on the characteristics of probiotics. Probiotics are effective at ameliorating immune disease, alleviating glucose intolerance, and improving constipation and diarrhea. Furthermore, they have anticancer and antitumor effects, preventive effects against cardiovascular disease, antidiabetic effects, antioxidant effects, antibacterial effects, and they produce useful metabolites. It has been demonstrated that oral probiotics are effective in eliminating halitosis and forming a favorable oral ecosystem, by creating an environment that is not readily inhabited by harmful bacteria, such as Streptococcus mutans, which produces lactic acid and causes tooth decay, or Porphyromonas gingivalis, which causes gum disease.As a result, oral probiotics are being considered not only as therapeutics against diseases, but also as preventive agents for the maintenance of a healthy oral balance. In spite of some limitations, clinical trials are currently underway, and this study can provide evidence to support the use of probiotics to improve oral health conditions, including dental caries, periodontal disease, and Candida colonization.

The purpose of this study is to identify the nature of the inpatient service quality of national university hospital, and based on that, to examine the relationship of hospital inpatient's perceived quality, overall satisfaction, customer loyalty(intention of revisiting, intention of oral transmitting). To carry out these objectives, first we analyzed the dimensions of inpatient care service quality using SERVQUAL scale. The SERVQUAL scale is based on the gap theory, that is, the difference of patients' expectations and the actually received medical care service in hospital. On the basis of this theory, we measured the inpatient's perceived service quality, overall patient satisfaction and customer loyalty. Data were collected by self-administered questionnaires at a 809 bed national university hospital. These questionnaires measuring the service quality were distributed to 400 inpatients. The data samples are 347 cases in final. The response rate was 86.8%. Firstly, to categorize inpatient service quality in hospital, the factor analysis was performed on 48 items. The reliability and validity of these items was evaluated. Finally to explore the relationship of service quality, overall satisfaction, and customer loyalty, the multiple regression and logistic regression analysis are used. This study shows firstly, the dimension of inpatient service quality was categorized into 7 dimensions, that is, kindness, medical service, nurse caring, environment, facilities, appropriateness and access. Secondly, the reliability and validity of inpatient service quality items was satisfied. Thirdly, as a result of multiple regression analysis, the effect of inpatient's perceived service quality, especially, nurse caring(P<0.01), environment (P<0.01), facilities, appropriateness and access variables(P<0.05), on overall satisfaction was statistically significant. Lastly, in case of the effect on customer loyalty as a intension of oral transmitting, medical service(P<0.05), environment(P<0.01) and overall satisfaction(P<0.01) are statistically significant. Also, in case of intension of revisiting, medical service, environment, access, and overall satisfaction variables are significant factors. In conclusion, to maintain the satisfaction and customer loyalty on national university hospitals, the efforts to improve the inpatient service quality, especially, environment, medical service, and access factors might be needed.

In this study, the characteristics and oral health status of manufacturing workers were investigated to confirm the factors affecting their risk of developing dental caries and to prepare basic data for developing oral health promotion programs for such workers. A self-administered questionnaire survey and saliva microorganism examinations (S. mutans and Lactobacillus tests) were conducted from July 1 to August 1, 2014 targeting the manufacturing workers in the Busan and Gyungnam areas, to confirm the factors affecting dental caries development among manufacturing workers. As a result, the risk of dental caries was found to be higher in the workers who worked for 10 hours or longer a day than in those who worked for less than 10 hours a day, and in the smokers than in the non-smokers. A 1-point increase in the brushing pattern score resulted in 0.044 times less risk of dental caries development in the S. mutans test and 0.004 times less risk in the Lactobacillus test Therefore, systematic support is needed to improve the work environment of manufacturing workers, along with continuous oral health education in workplaces.

Background: This study was conducted to investigate the heat stress and semen quality among male workers in a steel industry in Iran and investigate the relationship between heat stress indices and semen parameters. Methods: The study was conducted on workers exposed (n = 30) and unexposed (n = 14) to heat in a steel industry. After obtaining a brief biography of the selected employees, scrotal temperature, oral temperature, and environmental parameters were measured, and their semen samples were analyzed according to the procedure recommended by the World Health Organization. The heat stress indices, including wet-bulb globe temperature (WBGT) and predicted heat strain (PHS), in their workplace were calculated according to environmental parameters (ISO 7243:1989 and 7933:2004, respectively). Results: Time-weighted averages of WBGT and PHS ($35.76^{\circ}C$ and 491.56 $w/m^2{\frac{w}{m^2}}$, respectively) for the exposed group were higher than threshold limit values. The mean difference of environmental, physiological, and semen parameters (exception: pH of semen), and also WBGT and PHS indices were statistically significant (p < 0.05) between the two groups. Mean semen parameters were in the normozoospermic range. WBGT and PHS indices showed significantly "negative" correlation with physiological parameters (scrotal and oral temperature) and most semen parameters (semen volume, sperm morphology, sperm motility, sperm count; p < 0.05); moreover, the correlation of WBGT with these parameters was stronger than PHS. Conclusion: Semen parameters of the studied workers exposed to heat were in the borderline level of normozoospermic range, and their semen parameters were significantly lower than controls. For better assessment of occupational environment concerning physiological and semen parameters in steel industries, WBGT can be a more useful index.
