This study will be used as basic data to hold clinical training effective by researching and analyzing frequency, satisfaction and stress for the clinical practice of dental hygiene course students. The survey was undergone from Feb. 1, 2014 to Mar. 31 for 219 dental hygiene course juniors who had experienced clinical training in 3 year colleges located in Daejeon and Chungcheong Province. From the study, general and university hospital holds the highest satisfaction in clinical practice and dental offices in acquiring skills. Also, a significant difference is shown between the frequency and satisfaction according to clinical training sheets. The highest degree of stress is shown in dental offices for 'toothbrushing training and dental health education' and in general and university hospital for 'patient counselling'. Therefore, consideration should be made to establish the direction of education, standard criteria and evaluation method for student clinical training to raise its effectiveness.

Objectives: The purpose of this study was to contribute to the development of an oral hygiene care program for patients with dementia by understanding the oral care status and oral health knowledge of care workers and caregivers with regard to patients with dementia. Methods: For about two months from May to June 2018, a survey of care workers and caregivers working in long-term nursing homes and elderly-specialized nursing hospitals was performed, and 442 people were selected for the final analysis. The frequency and percentage were calculated to understand the oral care status and oral health knowledge regarding patients with dementia, and an independent t-test was conducted to determine the difference between the elderly oral health knowledge of care workers and caregivers. Multiple regression analysis was also carried out to examine factors affecting elderly oral health knowledge. Results: With respect to the factor of oral health education in elderly oral health knowledge, oral health knowledge was shown to be highest when participants responded that education was unnecessary (p<0.001), and regarding the will to participate in oral health education, oral health knowledge was highest when participants responded as having no desire to participate (p<0.05). Conclusions: These results suggest that a standard manual should be developed for the accurate and qualitative management of oral hygiene care tasks performed by care workers and caregivers who are in charge of oral care for patients with dementia in order to provide continuous and systematic oral care.

Background: Various oral health management programs in Korea affect the oral health improvement in the elderly Several studies have been conducted to date; however, those studies have not shown uniform results due to the differences in research methods or designs. Hence, this study aimed to review the overall research trends of the reported oral health care programs for the elderly in Korea, verify their effects, and clarify them based on the systematic literature review. Methods: The literature search selected intervention studies that applied the oral health care program for the elderly in Korea from 2001 to 2020. Following the COre, Standard, and Ideal (COSI) models presented by the US National Library of Medicine, we selected databases including Korean studies Information Service System (KISS), ScienceOn, Research Information Sharing Service (RISS), DBpia, PubMed, and Google Scholar. Of the 1,335 studies searched using keywords, titles, and abstracts, 21 were finally selected based on primary and secondary exclusion criteria. Results: The most frequent intervention period was 4 weeks, and the number of interventions varied between 2 and 90 times. As for the type of intervention, 14 studies that conducted both theory and practice were the most frequent. Significant differences in the clinical indicators, such as calculus, halitosis, salivation rate, swallowing function, and dry mouth, were found in most oral health care programs. Conclusion: Based on the results of this study, the intervention program needs further verification using multiple indicators in future studies. In addition, a study extending the intervention period and the number of samples is considered necessary for verifying continuous effectiveness of the intervention program.

Backgrounds: Occupations are grouped on the basis of similarity in tasks and duties performed. Standard occupational classification (SOC) is a tool for organizing all professions into a clearly defined set of groups according to the tasks and duties undertaken in the respective jobs. Objectives: The major objective of this study is to comprehensively review how a SOC system is used in occupational and safety fields such as surveillance, exposure monitoring, occupational epidemiological study, management of carcinogens and analysis of occupational accidents. Methods: We summarized the cases, policies and regulations used in SOC systems in advanced countries and as they appear in articles Results: We found that SOC systems have been widely used in various areas of occupational safety and health in the US, the UK, Finland, and the EU. In general, it is highly common to use SOC in the analysis of occupational accidents and diseases and to identify factors causing those accidents. The SOC system is also used not only for surveillance of exposure to hazardous agents and occupational health, but to manage carcinogens. In order to adjust the effects of a particular job, SOC is used in the general population health area. The Ministry of Employment and Labor (MOEL) has never used or introduced an SOC system. There have been no cases of the application of a SOC system to either the occupational safety and health field or to health surveillance for the general population in Korea. Conclusions: We suggested a need to introduce an SOC system in several occupational safety and health activities, such as work environment measurement, analysis of occupational accidents, specific physical examination and surveillance systems, etc.

The changes in korean economic environment, from quantitative to qualitative growth of economy, go with making desperate efforts, that is, companies have put through many technical improvements, quality control, improvement of service, and so forth. Enterprises cut the number of employees through labor-management adjustment, so that a shortage of labor caused. An increase in intension of labor brought about growing the proportion of occupational diseases which is musculoskeletal diseases. Because of a rapid change in society and a change in our circumstances, we have many difficulties in examine a business disease closely. In support corroboration of relevance on admission of business, a criterion for dudging afford a basis for a causal relationship of medical science, take the state of working conditions into consideration, and at the same time, give a adaptable decision based on the purpose and point of "The Labor Standard Law" as well as "The Law about Industrial Accident Compensation insurance". In conclusion, it is necessary for the dental hygienists 10 reduce the on-duty hours a day, to make good postures in working, and to remove the stressful conditions in order to reduce the incidence of the lumbago. Good working postures, appropriate rest time, and early detection, care and education of the lumbago could be recommended for the dental hygienists.

Objectives: The present system of occupational safety and health law gives priority to traditional command and control regulations. However, this may give rise to problems such as the delay of standard-setting and shortages of human resources. The aim of this study is to examine the usability of private standards in occupational safety and health systems. Materials: After the limits of occupational safety and health law were examined, an application plan for private norms (EN, as enforced in the EU) and occupational safety and health management systems (OSHMS) was investigated. Results: The utilization of private norms and OSHMS may address the limits of the current legal system. In particular, OSHMS is known internationally as a measure for achieving improvements in overall occupational safety and health performance. As a result, occupational safety and health law and private norms/OSHMS are complementary to one another. Conclusions: Even though the utilization of private standards may give rise to legal questions, such standards as complementary measures to traditional command and control regulations need to be utilized progressively in occupational safety and health systems.

This research was conducted to analyze the perception of the dental hygienists who work in ordinary dental clinics regading patient safety culture and to analyze the related elements. As for the research subjects and methods, 233 dental hygienists who work at the dental clinics located in Daegu, Gyeongbuk and Jeonnam were targeted from February 6, 2012 to March 5, 2012 to administer survey by utilizing patient safety culture recognition tool. Collected data was subjected to the SPSS 18.0 program to calculate average and standard deviation, and to carry out t-test, ANOVA and multiple regression analysis. Dental hygienists' level of perception towards patient safety culture was mid level, and it was demonstrated that there is a correlation with age, work experience at department, title and type of department that affect level of perception towards patient safety culture. In conclusion, Since this research targeted only a limited number of dental hygienists, it is necessary to be cautious about over-interpreting the results. Above anything, it is necessary to carry out repetitive research by targeting medical professionals of diverse jobs.

This study was performed to identify the current status of work environment management and to provide appropriate recommendations for small scale industry with less than 5 workers from September, 2000 to October, 2000 in Seoul city and Gyoung-gi province. The 211 companies were surveyed by checklist included the elements of management of work environment, hazardous chemicals, MSDS, personal protective equipment, and ventilation system. The proportion of metal products manufacturing and printing industries are 25.6 % and 22.3%, respectively. The daily working hours in printing industry is longer than others. The industries that produce potentially hazardous agents, such as noise, dust, metal, organic solvents, radiation and chemical material are pulp, plating, machinery, and printing, respectively. In above industries, only 2.8 % of those recognised and had MSDS. The proportion of companies providing fire extinguishers, safety showers are found to be 13.3 %, 7.1 %, respectively. Only 24.2 % of companies provided personal protective equipment to the workers. The ventilation system was operated in most of companies. But local exhaust ventilation system is provided to 22.3 % of those, also had not been annually inspected. This study showed that the current status of occupational safety and health was not appropriate for workers in small scale industries. It is suggested that annual physical examination have to be performed, MSDS usage must become widespread, and employer and emplyees in small scale industry should be educated for the treatment and storage of hazardous chemicals to improve the occupational safety and health of the working environment. also, regulatory standard has to be applied to local exhaust ventilation system in small scale industry to improve the working condition.

Background: Particulate matter (PM) has been extensively observed due to its negative association with human health. Previous research revealed the possible negative effect of air pollutant exposure on oral health. However, the predictive model between air pollutant exposure and the prevalence of periodontitis has not been observed yet. Therefore, this study aims to propose a predictive model for the number of patients with periodontitis exposed to PM and atmospheric factors in South Korea using deep learning. Methods: This study is a retrospective cohort study utilizing secondary data from the Korean Statistical Information Service and the Health Insurance Review and Assessment database for air pollution and the number of patients with periodontitis, respectively. Data from 2015 to 2022 were collected and consolidated every month, organized by region. Following data matching and management, the deep neural networks (DNN) model was applied, and the mean absolute percentage error (MAPE) value was calculated to ensure the accuracy of the model. Results: As we evaluated the DNN model with MAPE, the multivariate model of air pollution including exposure to PM_2.5, PM₁₀, and other atmospheric factors predict approximately 85% of the number of patients with periodontitis. The MAPE value ranged from 12.85 to 17.10 (mean±standard deviation=14.12±1.30), indicating a commendable level of accuracy. Conclusion: In this study, the predictive model for the number of patients with periodontitis is developed based on air pollution, including exposure to PM_2.5, PM₁₀, and other atmospheric factors. Additionally, various relevant factors are incorporated into the developed predictive model to elucidate specific causal relationships. It is anticipated that future research will lead to the development of a more accurate model for predicting the number of patients with periodontitis.
