This study attempted to determine the degree of asbestos release from the aging slate roof by comparing the asbestos content in the slate roof rain gutter with a colored steel plate (tin plate) over the slate roof. Four slate roof houses located in Haengmok-ri, Asan-si, Chungcheongnam-do, and one house constructed with a colored steel plate on the slate roof were selected to collect the sediment of the roof rain gutter. The asbestos fiber content was calculated by a point counting method using a polarization microscope after pretreatment with conversion treatment and hydrochloric acid treatment. The average asbestos content of the four slate roof rain gutter were 1.89%. However, asbestos was not detected in the Slate covering roof rain gutter, which were constructed on the slate roof. Asbestos fiber content was the highest at 2.89% in the slate roof rain gutter installed in 1976, followed by 2.44% in 1953. From the above results, it is necessary to minimize secondary damage as asbestos fibers released from slate roof houses to the surrounding atmosphere or leaked from slate roofs as rainwater may cause soil pollution and seriously affect residents' health. Although covering with colored steel plates (tin plates) has been shown to prevent the leakage of asbestos fibers to some extent, it is believed that a policy alternative to remove the slate roof as soon as possible is needed to solve the fundamental problem.

Objective: This study was carried out to investigate the effect of dentifrice containing green tea extract, sodium monofluorophosphate and calcium carbonate on dental plaque and gingivitis by periodic measurements. Methods: Oral examination items were measured by papillary marginal attached (PMA) index, Talbott’s gingival index, patient hygiene performance (PHP) index, and Turesky’s plaque index. Results: PMA index showed statistically significant difference in the control group (p<0.05). Talbott’s gingival index measurements showed statistically significant differences in the control group from 8 weeks after the start of the study (p<0.05). As a result of PHP index measurement, statistically significant differences were observed in the experimental group from the control group after 4 weeks (p<0.01). And Turesky’s plaque index measurement, statistically significant differences were observed in the experimental group from the control group after 4 weeks (p<0.01). Conclusion: These results suggest that dentifrice with green tea extract, sodium monofluorophosphate and calcium carbonate can be effective in reducing gingivitis and dental plaque.
Estimation for the extreme value distribution under progressive Type-I interval censoring
Sol Ji Nam,Suk Bok Kang 한국데이터정보과학회 2014 한국데이터정보과학회지 Vol.25 No.3
In this paper, we propose some estimators for the extreme value distribution based on the interval method and mid-point approximation method from the progressive Type-I interval censored sample. Because log-likelihood function is a non-linear func-tion, we use a Taylor series expansion to derive approximate likelihood equations. We compare the proposed estimators in terms of the mean squared error by using the Monte Carlo simulation.

Background:?Fall is one of the most important causes of injury in the elderly and it triggers calamitous consequence in independence of daily living, and quality of life. The Korean Association of Internal Medicine and the Korean Geriatric Society developed evidence-based guideline for fall prevention and release conjointly. This study aim to analyze the results of fall risk assessment and examine the effects of structured physical activity program in the community-dwelling elderly based on the guideline.?Methods:?We registered community dwelling older persons (≥65 years) who live in Seongnam-si between April and May 2016. 29 participants were enrolled from Seongnam home visiting program, 23 were enrolled from daycare program in Seongnam central welfare center and 12 were recruited through announcements in the welfare center. All participants examined multidimensional fall risk assessment including the initial physical performance test and frailty assessment. They joined moderated-intensity physical activity program conducted in a welfare center or at home 2 times per week over 4 weeks. After 4 weeks of physical intervention, we followed up the physical performance test.?Results:?Participants of home visiting group and daycare program group were more frail than welfare recruitment group, but not statistically significant (Home visiting program group: Robust 24.1%, Pre-frail: 44.8%, Frail: 31.0%; daycare program group: 47.8%, 34.8%, 17.4%; welfare recruitment group: 50.0%, 41.7%, 8.3%, p=0.088). After 4 weeks physical activity program, grip strength was significant improved in home visiting group and daycare program group (12.0±4.8 vs 15.8±5.3, 12.7 ±5.8 vs 16.1±6.4, p<0.001, p=0.004). POMA score was improved in home visiting group (22.9±5.9 vs 24.3±5.2, p=0.019). But welfare recruitment group and daycare program group showed no improvement (28.0 vs 28.0, 26.4±3.1 vs 25.4±3.8, p=0.173).?Conclusions:?A structured physical activity program improved physical performance in the elderly over 1 month. It especially effected on home visiting group. This finding suggests that mobility have more benefits from such a program in vulnerable older adults.

S-735 Socioeconomic status is associated with frailty in Korean old adults: Data from KHANES
( Sol-ji Yoon ),( Jung-yeon Choi ),( Min-gu Kang ),( Sun-wook Kim ),( Cheol-ho Kim ),( Kwang-il Kim ) 대한내과학회 2016 대한내과학회 추계학술대회 Vol.2016 No.1
Background:?Low Socioeconomic status (SES) is a common risk factor of poor health in older adults. Frailty is also a common risk factor for morbidity and mortality in older adults. Although the existence of a social gradient in the frail elderly is known previously, there are no studies how SES affects the health status of the frail elderly. This study aims to examine the relationship between SES and frailty and analyze how SES affects frailty in Korean older adults.?Methods:?This study use the data from Korean Health and Nutritional Examination Survey (KHANES). It is a cross-sectional population study and designed to assess the health related behavior, health condition, and nutritional state of Korean. Of 4557 participants (≥ 65 years) in 6th cycle KHANES (2010-2012), excluding of 1,268 who were not answered parents’ educational level, we analyzed 3,289 participants. We used the frailty index using 41 deficits in the data. The relationships between difference indicators of SES and frailty were assessed in multivariable logistic regression models adjusted for potential confounders.?Results:?Of the samples, 1,199(36.4%) were robust, 1,112(33.8%) were prefrail and 978(29.7) were frail. In adjusted models, low level of education was associated with frailty (odd ratio [OR]: 3.16, 95% confidence interval [CI]: 2.40-4.54). Frailty also related with low level of occupation during midlife (OR: 2.97, CI: 2.00-4.38) and poor financial security (OR: 1.79, 95% CI: 1.48-2.16). The education/occupation level and marital status were related to health behaviors like smoking, drinking and irregular hospital visit (p<0.001).Conclusions:?The odds of frailty are increased as lower education/occupation level and unmarried/divorced/widowed status. The education/occupation level and marital status are related to health behavior, which may influence on glucose and BP control.
Frailty and Disability in Diabetes
Sol-Ji Yoon,김광일 대한노인병학회 2019 Annals of geriatric medicine and research Vol.23 No.4
Diabetes is an important health problem with the population aging. Previously, it is well established that diabetes is associated with microvascular and macrovascular complication, but recently, several data suggests that diabetes is accompanied with frailty as well as disability among the older adults. Considering the clinical significance of frailty and disability, it is important to understand the pathway from diabetes to frailty and/or disability. Additionally, it is strongly recommended to find a new therapeutic intervention are required to meet the increasing demand of managing older diabetic patient with the population aging.
