Objectives: This study aimed to confirm the association between cognitive function and oral health status in the elderly. Methods: In this study, 5,794 respondents, aged 55 or older, who had participated in the 7th aging research panel survey were used. Statistical analyses were performed using a complex samples cross-tabulation analysis, complex samples general linear model, and a complex sample multinomial logistic regression analysis. Results: After analyzing the cognitive function of the elderly according to their oral health conditions, it was found that suspicions of dementia (19.6%) and cognitive function decline (25.9%) were more common for those who wore dentures than for those who did not wear dentures (p<0.001). Compared to those who did not wear dentures, those who wore dentures were linked to a 1.665 times higher suspicion of dementia (p<0.001). In comparison, cognitive decline was 0.964 times lower when the number of natural teeth increased by 1, and it was 0.941 times lower when the oral health evaluation index for the elderly increased by 1 point (p<0.001). Conclusions: As a result of this study, it was confirmed that cognitive function and oral health status are related in the elderly. Therefore, systematic measures for oral health management and oral health promotion should be prepared in tandem with awareness of possible cognitive decline in the elderly.

The objective of this study is to examine a releasable asbestos sampler developed for measuring friable asbestos from soil to air controlled by wind velocity and water contents. Asbestos contaminated soil with 3.75% at the Sinsuk-asbestos mine was sampled, air-dried and sieved to 100 mesh, then homogenized during 24 hours' agitation. Various wind velocities, 1 m/s, 2 m/s, 3 m/s, and 5 m/s, were applied to evaluate releasable characteristics of the releasable asbestos sampler. In addition, soils with 1.0%, 3.4%, 4.4%, 11.0%, 16.2%, and 20.0% of water contents were also examined the amount of friable asbestos by the releasable asbestos sampler. Collected soil and air samples were analyzed by polarized light microscopy (PLM) and phase contrast microscopy (PCM), respectively. Those contents were applied to calculate an excess life cancer risk (ELCR). This study also discussed the relationship with risk assessment by a weeding scenario of activity based sampling (ABS) and field applied releasable asbestos sampler. The result was shown that friability of asbestos in soil increased with wind velocity and decreased with water content. In comparison with ELCR results, over 10E-4 of cancer risk was found in condition on < 5% water content and > 3m/s wind velocity.

Objectives: The purpose of this study was to compare the value and utility of certain oral health indicators in adults. Methods: The data used for analysis was obtained from the 6<sup>th</sup> Korean National Health and Nutrition Examination Survey (2013-2014). The study subjects were 7,729 adults aged between 20 and 64 years. The oral health indicators used for the analysis were T-Health (tissue health index), FS-T (functioning teeth index), and DHC of 1st molar (dental health capacity of the first molars). Descriptive statistical indices for oral health indicators were obtained (mean, skewness and kurtosis, and coefficient of variation). The correlation among oral health indicators, DMF, and sound tooth structure was analyzed. Results: The oral health indicator scores had an abnormal distribution. DHC of 1st molar is found to be the most reliable indicator because it most accurately reflects the oral health decline that occurs as a result of aging. In all ages, DHC of 1st molar marked the lowest value in skewness and kurtosis. However, the skewness and kurtosis values of T-Health in adults younger than 44 years old were found to be the lowest among all age groups. FS-T is believed to most accurately reflect oral health status as it has a high correlation with sound tooth structure and sound tooth surfaces. T-Health is evaluated to most accurately reflect oral disease indicators as it appears to have a high correlation with DMF and high caries risk. Conclusions: The oral health indicators T-Health, DHC of 1st molar, and FS-T have distinct characteristics that can serve as different health indices. Therefore, they can each be utilized in various fields of oral epidemiology.
