Purpose: This study utilizes big data from the 8th (2021) National Health and Nutrition Examination Survey to determine first, the relationship between chewing discomfort in the elderly and some systemic diseases and second, whether oral diseases and oral health problems are related to systemic diseases. Since this may have an impact, we aim to provide basic data to facilitate the expansion and emphasize the importance of integrated health management education. Methods: Original data from the 8th (2021) National Health and Nutrition Survey, conducted by the Korea Centers for Disease Control and Prevention, were analyzed using SPSS Version 21.0 (IBM). A complex sample frequency analysis was conducted to confirm the general and health-related characteristics of the study subjects, and a complex sample cross-analysis was conducted to determine chewing discomfort according to both general and health-related characteristics. Complex sample multiple logistic regression analysis was conducted to determine the effect on chewing discomfort. Results: In order to analyze the factors that affect chewing discomfort, the general characteristics that showed significant differences in chewing discomfort were adjusted for age, personal income, education level, basic livelihood security, high blood pressure, subjective health status, and subjective oral health. It was found that the condition had a statistically significant effect on chewing discomfort. Conclusion: The findings of this study demonstrate that high blood pressure, subjective health status, and subjective oral health status affect chewing discomfort; hence, measures such as developing and operating programs to improve national oral health are needed. We hope that our study will be used as basic data for research into chewing discomfort and systemic diseases in the elderly.

The present study reports on the results of a risk survey of machinery safety at a shoe factory in Qingdao, China. The aim is to decrease industrial accidents and increase worker job satisfaction by searching for a change from a trend analysis and making improvements in problem areas. The first risk survey for machinery safety was carried out in April 2005. Based on the analysis of the survey results, machinery safety devices was installed in the factory by using CATlA V5. Also, we investigated job satisfaction concerning working apparatus and work tool improvement in a questionnaire about the working environment. The second survey of machinery safety was carried out in September 2005. We are in the process of comparing the first survey results with the second survey results in order to analyze decreasing trend in industrial accidents and improvement in job satisfaction. So far the data have shown improved short-term turnover and absenteeism. It means CATIVA V5 and CFR has had positive effect regarding safety in shoe manufacture industry. The survey with CATIVA V5 and CFR will be expanded to other East-Asian countries including Vietnam. The hope is that the present approach could make a significant contribution toward improved safety.

Purpose: This study aimed to evaluate the effect of information regarding health and safety risks on the subjective health status of workers using data from the Fifth Korean Working Conditions Survey. Methods: Among the survey respondents, 30,094 people classified as salaried workers, of which 8,513 (28.3%) used protective equipment. Results: Although the majority of workers using protective equipment reported being well-informed about safety and health risks, 15% of them were still insufficiently informed. Multivariate analyses have shown that the subjective health status of workers using protective equipment was significantly better if they received sufficient information. When the workers using protective equipment were classified by the kinds of hazards they were exposed to, the satisfaction of information was also significantly beneficial for the subjective health status of all groups. However, in workers who did not use protective equipment, information satisfaction did not appear to be a significant factor. Conclusion: These results suggest that when providing information on safety and health risks, it is necessary to focus on workers using protective equipment, for whom the effects of the policy are clearly expected.

Background: The type of payment is one of the important factors that has an effect on the health of employees, as a basic working condition. In the conventional research field of occupational safety and health, only the physical, chemical, biological, and ergonomic factors are treated as the main hazardous factors. Managerial factors and basic working conditions such as working hours and the type of payment are neglected. This paper aimed to investigate the association of the type of payment and the exposure to the various hazardous factors as an heuristic study. Methods: The third Korean Working Conditions Survey (KWCS) by the Occupational Safety and Health Research Institute in 2011 was used for this study. Among the total sample of 50,032 economically active persons, 34,788 employees were considered for analysis. This study examined the relation between the three types of payment such as basic fixed salary and wage, piece rate, and extra payment for bad and dangerous working conditions and exposure to hazardous factors like vibration, noise, temperature, chemical contact, and working at very high speeds. Multivariate regression analysis was used to measure the effect of the type of payment on working hours exposed to hazards. Results: The result showed that the proportion of employees with a basic fixed salary was 94.5%, the proportion with piece rates was 38.6%, and the proportion who received extra payment for hazardous working conditions was 11.7%. Conclusion: The piece rate was associated with exposure to working with tight deadlines and stressful jobs. This study had some limitations because KWCS was a cross-sectional survey.

Objectives: This study aimed to investigate the effect of the oral health status on risk factors for obstructive sleep apnea (OSA) using data from the 2019 National Health and Nutrition Examination Survey. Methods: Of a total of 2,422 persons, 1,295 and 1,127 were categorized into the control group (CG) and OSA risk group (OSARG), respectively. The effect of the oral health status on OSA risk factors was presented in Model 1 by performing a complex sample linear regression analysis. Results: Our findings showed that OSA risk factors decreased by 0.075 points when there were no speaking problems with demographic characteristics adjusted. In addition, when systemic diseases were adjusted for, OSA risk factors decreased to 0.074 points (p<0.05). Conclusions: Therefore, in order to reduce oral problems that affect OSA risk factors, dentists and dental hygienists should seek accurate recognition of OSA and effective oral care methods.
