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: 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.

Purpose: The purposes of this study were to develop a Minimal Insomnia Screening Scale for Korean adults (KMISS) and to evaluate psychometric properties and discriminant ability of the developed scale. Methods: Data from a cross-sectional survey of 959 Korean adults were analyzed to develop the summated insomnia scale, which was evaluated in terms of reliability, validity, and discriminant ability by receiver operating characteristics (ROC) curve analysis. Results: Item-total correlations ranged between .71-.79 and Cronbach’s α was .87. Adequate validity was also evident. ROC-curve analysis showed area under ROC was .87 (95% CI: .84-.90) and identified the optimal cut-off score as ≤ 20 (sensitivity, .83; specificity, .75; positive/ negative predictive values, .40/.95). Using this cut-off score, the prevalence of insomnia in the study sample was 26.3% and most frequent among women and the oldest group. Conclusion: Data supports the psychometric properties of KMISS as a possible insomnia screening instrument. KMISS also shows promise as a convenient ultra-short screening measure of insomnia for adults and epidemiological studies in community health care settings.

본 연구는 생명공학정책을 중심으로 줄기세포연구개발의 정부예산지출에 있어 단절이 발생되는지 여부와 단절의 발생원인 점증적 비점증적 변동요인에 대해 단절균형이론을 통해 분석하였다 단절이 발생하는 원인은 복제인간 이브 탄생 파문이나 황우 . ‘ ’ (2002. 12)석 사태 와 같은 부정적이고 충격적인 사건을 비롯하여 세계의 기술경쟁 심화 (2005. 11)대통령의 정책의지에 기인하였다 특히 가시적인 연구성과의 창출이나 대통령 및 정부의 높은 관심과 육성정책 선호 선진국 투자 강화 연구규제정책의 부재는 줄기세포연구 , R&D개발 정부예산지출의 비점증적인 변동요인으로 작용하였다 그러나 충격사건에 의한 부정적 이미지와 체세포복제배아 줄기세포연구의 실효성을 둘러싼 내부적인 갈등이 발생할때 예산지출이 점증적으로 변화됨을 알 수 있었다 부정적인 충격사건에도 불구하고 정부의 예산지출 규모면에서 감소되지 않은 것은 줄기세포분야가 잠재적인 의료적 경제적 가치를 지니는 차세대 신성장동력 분야이기 때문에 세계의 기술주도권을 선점하기 위한 것으로 볼 수 있다 본 연구를 통해 줄기세포연구개발 정부예산지출은 과학기술의 특성상국내외의 이슈에 영향을 받지만 국내 이슈에 더욱 크게 영향을 받는다는 것을 알 수 있었다. This study aims to analyzed dynamics of biotech policy national R&D budget expenditure. To explore when occurred a punctuation of R&D budget expenditures to human stem cell Research and Development programs and what factors affect this changing of budget expenditure, we applied punctuated equilibrium model to analyze incremental and non-incremental Human stem Cell R&D program budget expenditure dynamics changing, We can found several factors to affect these R&D budget expenditure changing. First is negative and focusing event such as Prof. Wooksuk Hwang Scandal(2005. 11) as well as creation of cloned humans, Eve. Second is increasing technology competition among global countries and their expanding investment to R&D policy. Third is President's biotech policy intention and preference to biotech development policies and programs. Fourth is non-existing research ethic regulation in Korea. Except negative or focusing events factors, the other factors influence non-incremental dynamic changing or punctuation of budget expenditure. We also found that negative focusing event affect influence incremental changing or slight declining rather than punctuation what we expected. From this results we conclude the biotech R&D budget expenditure is decreasing incrementally and increasing punctually when visible research results occurs.

연구개발(R&D)활동이 GDP에 미치는 영향 분석

김인자(In Ja Kim),오윤정(Yun Jung Oh),김연희(Yeon Hee Kim) 한국기술혁신학회 2016 기술혁신학회지 Vol.19 No.3

기술경제이론에서는 연구개발을 통한 기술혁신이 경제성장의 핵심요소로 간주하고 있다. 본 연구는 사회학, 경영학에서 사용되고 있는 경로분석(path analysis)방법을 활용하여 연구개발 투입변수(GDP 대비 총 연구개발비 비중, 총 연구원수, 이공계 학사학위 비율)가 매개변수인 산출변수(과학기술논문수, 특허등록수)를 통해 경제적 성과변수인 GDP에 어떻게 영향을 미치는지 분석하였다. 연구개발 활동 변수 중 과학기술논문수(0.967), 총 연구원수(0.373), 총 연구개발비 비중(0.191), 특허등록수(0.049), 이공계 학사학위 비율(0.007) 순으로 GDP에 가장 큰 효과를 가지는 것으로 나타났다. 총 연구개발비 비중과 총 연구원수는 GDP에 직접효과보다 논문이나 특허를 매개로 하여 GDP에 미치는 간접효과가 더 크게 나타났다. 이는 연구개발비 규모나 GDP 대비 비중을 꾸준히 유지시킬 필요성과 고급인력양성의 중요성을 시사한다. 또한, 과학기술논문수는 GDP에 가장 큰 효과를 가지는 것으로 나타나, 연구개발로 창출된 새로운 지식 및 기술이 공유 · 확산됨으로써 새로운 성과와 가치로 이어진다는 것을 시사한다고 할 수 있다. In technology economic theory, technology innovation through R&D is regarded as a core element of economic growth. This research analyzes how R&D input factor (R&D as a percentage of GDP, total number of researchers, the proportion of science and engineering degree) affects GDP, economic outcome variable, through mediating variable (S&T papers, patent registration). The most effective variable among R&D activity variables is following order: the number of S&T papers (0.967), the total number of researchers (0.373), the proportion of R&D expenditure (0.191), the number of patent registration (0.049), the proportion of science and engineering degree (0.007). It is that the proportion R&D expenditure and the total number of researchers shows greater indirect impact through S&T papers and patent than the direct impact on GDP. This implies the importance of high-quality human resources training and the necessity of maintaining the scale of R&D fund or the importance on GDP. Moreover, S&T papers turns out to have the greatest effect on GDP and implies new outcome and value by sharing and expanding new knowledge and technology created by R&D.

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^th 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.
