본 연구에서는 OECD test guideline 데이터를 이용하여 graph기반 딥러닝 모델들의 성능을 비교하고자 한다. OECD TG는 화학물질들이 인체와 환경에 미칠 잠재적 영향에 대해 시험하는 방법이며, 많은 실험이 동물실험을 통해 독성을 확인한다. 동물실험은 많은 시간과 비용이 들며, 윤리적 이슈가 있어 대안을 찾거나 최소화하는 방법들이 연구되고 있다. 딥러닝은 화학물질을 활용하는 다양한 분야에서 사용되고 있으며, 독성예측 분야에도 사용되고 있으며, 특히 graph 기반 모델에 대한 연구가 활발하다. 우리의 목표는 OECD TG 데이터에 대한 graph기반 딥러닝 모델들의 성능을 비교하여 가장 성능이 좋은 모델을 찾는 것이다. 우리는 OECD에서 운영하는 웹사이트 eChemportal.org에서 OECD TG를 따른 결과를 수집하였으며, 전처리 과정을 통해 학습이 불가능하거나 부적절한 화학물질은 제거하였다. 수집된 OECD TG데이터와 화학물질 특성 예측 성능의 벤치마크 데이터셋인 MoleculeNet 데이터를 활용하여 5개의 graph기반 모델들의 독성 예측 성능을 비교하였다.

This study aims to analyze panel data using OECD Health data of 34 years to examine how significant the inequality of income is to the inequality of health. The data was from OECD's pooled Health data of 32 countries from 1980 to 2013. The process of determining analysis model was as follows; First, through the descriptive statistics, we examined averages and standard deviation of variables. Second, Lagrange multiplier test has done. Third, through the F-test, we compared Least squares method and Fixed effect model. Lastly, by Hausman test, we determined proper model and examined effective factor using the model. As a result, rather than Pooled OLS Model, Fixed Effect Model was shown as effective in order to consider the characteristics of individual in the panel. The results are as follows: First, as relative poverty rate(${\beta}=-19.264$, p<.01) grows, people's life expectancy decreases. Second, as the rate of smoking(${\beta}=-.125$, p<.05) and the rate of unemployment (${\beta}=-.081$, p<.01) grows, people's life expectancy decreases. Third, as health expenditure(${\beta}=.414$, p<.01) shares more amount of GDP and as the number of hospital beds(${\beta}=-.190$, p<.05) grows, people's life expectancy increases.

이 연구의 목적은 우리나라의 악성신생물 중 최근 증가율이 가장 높은 대장암에 대하여 우리나라와 OECD 국가들 간에 2000년 전(1990-1999)과 2000년 후(2000-2009)의 사망률과 잠재수명손실연수(PYLL)에 통계학적으로 차이가 있는가를 살펴본 후, 대장암에 대한 국가 간 비교와 변화의 추이를 파악하여, 보건정책, 보건교육 등을 위한 자료를 제공하고자 하였다. "OECD Health Data 2012"을 사용하여 OECD 회원국 중 자료가 불충분한 2개국을 제외한 32개국에 대하여 대응표본 T검정(Paired T test) 방법을 사용해서 2000년 전과 2000년 후에 통계학적으로 차이를 살펴보았다. 남자의 대장암 사망률은 우리나라를 포함한 8개국만 2000년 후에 증가하였고, 여자의 대장암 사망률은 우리나라와 칠레만 증가하였는데 증가폭은 남녀 모두 우리나라가 월등히 높았다. 대장암 잠재수명손실연수는 2000년후에 증가폭이 우리나라가 월등히 높았는데, 남성의 경우 증가율 2위인 멕시코보다 3배 이상 증가하였고, 여성의 경우 2000년 후에 통계학적으로 유의하게 잠재수명손실연수가 증가한 나라는 우리나라가 유일하였다. 따라서, 대부분 OECD 국가는 2000년 이후 대장암 관리가 적절히 통제되고 있는 반면, 우리나라는 그렇지 못한 것으로 보이며, 특히 향후관리에 있어 여성에서 보인 잠재수명손실연수의 증가 이유에 관한 후속연구가 필요해 보인다.

OECD 'Health Data 2007' 음주관련 지표를 살펴보면 우리나라의 주류 소비 수준은 OECD 30개국 중 22위에 해당한다. 또 우리나라의 1인당 음주량은 8.1L로 OECD 국가의 평균인 9.5L에 못 미치는 수준이나, 폭음하는 비율은 매우 높은 편이다. 또한, 술 마시는 문화가 사회적으로 조성된 우리나라는 음주에 대해 관대하게 생각하는 경향이 있다. 직장 생활을 하려면 술은 마실 줄 알아야 하고, 남자라면 술을 잘 먹는 게 자랑할만한 일이 되는 게 우리나라 문화이다. 특히 모임과 행사가 많은 연말에는 음주로 인한 사건 사고가 많이 일어난다. 이럴 때일수록 건강을 해치지 않는 음주에 대해 실천이 필요하다.

Objectives : This study aimed to examine the association between public social expenditure(PSE) and suicides in the 27 countries of the Organization for Economic Cooperation and Development(OECD) from 1980 to 2003. Methods : The age-standardized suicide rates and their annual change(%) were obtained from the OECD Health Data 2007. As a measure of social protection, the PSE(% GDP) was used. The covariates included the annual divorce rate(/100,000 population), fertility rate(number of children/woman aged 15 to 49 years), GDP per capita(US$ PPP), male unemployment rate(%), life expectancy(years) and alcohol consumption(liter/capita) for each country, which were all obtained from the OECD Health Data 2007 and the OECD Social Indicators 2006. Using hierarchical linear models that included these covariates, the effects of PSE on suicides(Model 1) and the annual percent change (Model 2) were examined(Model 3). Also, sub-sample analyses were done for six countries that experienced political/economic transition. Results : We could not find significant effects of PSE on suicides(Model 1), but we observed significantly negative effects on the annual percent change for men and women(Model 2). Such findings were replicated in the sub-sample analysis, and moreover, the effect size was much larger(Model 3). Conclusions : Our finding suggests that social welfare protection can be a pivotal factor for suicide epidemiology, and especially in countries experiencing a social crisis or transition.

Background: This study aims to utilize Organization for Economic Cooperation and Development (OECD) data to identify macroscopic determinants of health at national level and to utilize it in health policy development through comparison and analysis with Korea. Methods: The potential years of life lost (PYLL) were used as dependent variables and 19 indicators were selected as health determinants to be independent variables based on the results of previous studies. Data analysis was done using SAS ver. 9.4 package (SAS Institute Inc., Cary, NC, USA) and model used in technical statistics concerning PYLL by countries, multi-linearity test between independent variables and OECD economic studies were modified and used. Results: From 1994 to 2012, the average PYLL for OECD countries was 4,262.9 years, the highest in Estonia and the lowest in Iceland. As a result of the analysis using the fixed effect model, the significant variables affecting PYLL were four variables: gross domestic product, nitric oxide, tobacco consumption, and number of doctors. The health determinants that had more influence on the PYLL of Korean people compared to other OECD countries were tobacco consumption, calorie consumption, fat intake and total health expenditure. Conclusion: In order to effectively reduce unnecessary deaths, we must continue to strengthen our smoking policy and nutrition policies such as calorie and fat intake. It is necessary to prevent the increase of total health expenditure due to the increase in the prevalence of chronic diseases and to strengthen the public health aspect.

The Organization for Economic Cooperation and Development, which has continuously evaluated the performance of healthcare systems, has recently invested much effort into hospital performance measurement. The purpose of this paper is to introduce the hospital performance measurement programs operated by international organizations or at the national level based on the OECD's hospital performance project. Health Insurance Review & Assessment service (HIRA)'s quality assessment was analyzed based on the analytical framework of the OECD's hospital performance project. The hospital performance measurement programs of WHO, Canada, Australia, United States and United Kingdom are briefly explored, in view of the conceptual framework, key performance dimensions and indicators that are currently in use. The OECD suggested seven key dimensions of hospital performance: timeliness, efficiency, continuity, effectiveness and appropriateness, staff orientation, patient orientation and safety. The analysis of the quality assessment program of HIRA, which operates 36 diseases and procedures and 347 indicators, shows that the numbers of indicators are relatively small in the areas of safety, patient centeredness and efficiency. Continuity of care and staff orientation are not fully developed also, but the situations are similar in other countries. In conclusion, hospital performance measurement using stable and comprehensive data should be developed to improve overall system performance, and discussions on a conceptual framework that can lay out directions and key performance domains need to take into place.

Background: Health statistics of pharmaceutical use and expenditure are essential to make and implement evidence-based pharmaceutical policy. This study aims to demonstrate the methods and results of pharmaceutical consumption and sales in 2018 according to the sources and methods given by the Organization for Economic Cooperation and Development (OECD). Methods: The medication list contains 39,346 medicines both reimbursed and non-reimbursed by the National Health Insurance in 2018. We used the therapeutic categories based on Anatomic Therapeutic Chemical Classification of World Health Organization. This study analyzed National Health Insurance claims data and supply data generated from wholesalers to health care facilities. The indicators are defined daily dose (DDD), per 1,000 inhabitants per day and US$ per capita. Results: In South Korea, the number of medications to which DDD were assigned was 18,055 and it was 45.9% of the total number of medications on the list. The consumption in anti-infective for systemic use (J) and musculo-skeletal system (M) was higher than the mean consumption among the OECD countries. The pharmaceutical sales per person in Korea was also higher than the mean sales per person across the OECD countries. Conclusion: We sought to explain the methods to produce pharmaceutical consumption and sales statistics which we had submitted annually to OECD. Considering the characteristics of pharmaceutical statistics, a direct comparison should be approached with caution. Since the growth in pharmaceutical spending has greatly increased over the past decade, we need to monitor pharmaceutical consumption and expenditure consistently.

This study was carried out to analyze the present condition of high-price medical technologies in South Korea and to compare it with OECD countries. This study included 10 high-price medical equipments and used medical equipment registry data of Health Insurance Review Agency. The major findings of this study are as follows; Firstly, The number and growth of high-price medical equipments in South Korea is much higher than those in other OECD countries. There are many of high-price medical equipments even in clinics. Secondly, the percentage of old poor-quality medical equipments is very high, especially in clinics. This is because of high-price of medical equipments. The results of this study implicated that there is high possibility of inappropriate use of high-price medical technologies. This may result in the increase of health expenditure; therefore, there should be a kind of regulation policy to control amount and quality of medical equipment.

Health promotion policies have needed to assess in detailed and evidence-based work to set a policy goal and clear future directions of health promotion in Korea. To identify the major factors related with health promotion, we assessed the associations between public health outcome (potential years of life loss, PYLL) and national health determinants. For this purpose, we used a pooled cross sectional time-series regression analysis with corrected fixed effect models involving sixteen member countries of the Organisation for Economic Cooperation and Development during the period 1970 to 2001. The PYLL was positively associated with tobacco and alcohol consumption (model 1 and 2) and calories intake (model 2 and 3) while the PYLL was negatively associated with GDP, fruit and vegetable intake (model 2), number of doctors (model 3), coverage rates of health care security, and elderly population rates (model 4). In conclusion, health behaviors related with tobacco, alcohol, and nutrition were significant health determinants for health outcome. Overall analysis results of this study will provide a guidance toward improved macro- and micro-policy development for future health promotion policy in Korea.
