본 연구의 목적은 충남지역 NGO를 사례로 하여 NGO의 활동특성과 네트워크의 중심성 결정요인을 분석하는데 있다. 이를 위해 충남지역 3개 신문검색 통해 자료를 구축하고, NGO의 활동특성과 네트워크의 중심성 결정요인을 분석하였다. 주요 연구결과는 다음과 같다. 첫째, 충남지역 NGO의 활동특성을 살펴보면, 연평균 1.34회 활동을 하고 있다. 이들 활동은 주로 서비스적 활동, 협력적 활동, 1회에 6개 이상의 단체와 협력, 시군 중심의 활동, 대상 측면에서 대중지향적 활동, 방식 측면에서 비제도적 활동이다. 둘째, 연결중심성의 결정요인을 분석해 보면, 외향적 연결중심성에는 협력활동의 비중(+), 활동횟수(+), 협력기관수(+), 비NGO 협력단체 비중(-)이 영향을 미친다. 반면 내향적 연결중심성에는 활동횟수(+)와 비NGO 협력단체 비중(-)이 영향을 미친다. 셋째, 인접중심성의 결정요인을 분석해 보면, 외향적 인접중심성에는 비제도적 방식의 활동비중(+), 대중지향적 대상의 활동비중(+), 협력활동의 비중(+), 비NGO 협력단체 비중(+). 협력기관수(-)가 영향을 미친다. 그리고 내향적 인접중심성에는 비제도적 방식의 활동비중(+), 대중지향적 대상의 활동비중(+). 시군단위 활동비중(+), 서비스적 활동비중(-)이 영향을 미친다. 넷째, 사이중심성에는 활동횟수(+)와 협력기관수(+)만이 영향을 미친다. The purpose of this study is to look into NGOs in Chungnam region an example to investigate the activity characteristics of NGO cooperative network as well as its centrality determination factors. To this end, three kinds of Chungnam regional newspapers were analyzed and database was established to identify NGO activity characteristics and network centrality determination factors. Main findings of this study are as follows; First, in terms of the activity characteristics of NGOs in the Chungnam region, they were found to show 1.34 times of activity on average annually. These activities include mostly service activities, cooperative activities, cooperation with 6 or more groups at once, local activities, inside strategy activities in their target and non-institutional activities in their methodology. Second, degree-centrality determination factors were analyzed. The out-degree centrality was found to affect cooperative activity share (+), activity frequency (+), number of cooperation agencies (+), and share of non-NGO cooperative agencies (-). On the other hand, the in-degree centrality was found to affect the activity frequency (+) and share of non-NGO cooperative agencies (-). Third, closeness-centrality determination factors were analyzed. The out-closeness centrality was affected by the share of non-institutional activity (+), share of inside strategy activity (+), share of cooperative activity (+), share of non-NGO cooperative agencies (+), and number of cooperative agencies (-). The in-closeness centrality was found to be affected by the share of non-institutional activity (+), share of inside strategy activity (+), share of local activity (+), and share of service activity (-). Forth, the betweenness centrality was affected by activity frequency (+) and share of cooperative activity.

The purpose of this study is to analyze the structure of the cooperative network of Non Profit Organizations (NPOs) in Chungnam Region. To achieve the purpose, with the keywords of the names of NPOs, this researcher searched for the news articles written in 2009 to 2010 by three major daily newspapers in Daejeon and Chungnam Region and built a database. And then, the database was analyzed by the use of UCINET, a social network analysis program. The main results from the work are presented as follows. First, the lines and density of the cooperative network of NPOs in Chungnam Region were found low, whereas its the centrality of the cooperative network appeared high. Regarding each activity area, the lines and density were found low in all six areas, but the centrality was found somewhat high in local autonomy, educational and academic area, and cultural area. Secondly, the cooperative network of NPOs in Chungnam Region was found to be largely created. That is, 83.4% of the entire participants joined the sub-network. Regarding each activity area, sub-network was activated in local autonomy, welfare and environmental area, but was not activated in other areas. Thirdly, super network was found in the cooperative network of NPOs in Chungnam Region. In other words, from the perspective of areas, the cooperative network of NPOs in the local anatomy and welfare areas played a central role, and from the perspective of space, the cooperative network of NPOs in Cheonan, Asan, and Dangjin did so.

Mendelian Randomization Analysis in Observational Epidemiology

이관,임지연 한국지질동맥경화학회 2019 지질·동맥경화학회지 Vol.8 No.2

Mendelian randomization (MR) in epidemiology is the use of genetic variants as instrumental variables (IVs) in non-experimental design to make causality of a modifiable exposure on an outcome or disease. It assesses the causal effect between risk factor and a clinical outcome. The main reason to approach MR is to avoid the problem of residual confounding. There is no association between the genotype of early pregnancy and the disease, and the genotype of an individual cannot be changed. For this reason, it results with randomly assigned case-control studies can be set by regressing the measurements. IVs in MR are used genetic variants for estimating the causality. Usually an outcome is a disease and an exposure is risk factor, intermediate phenotype which may be a biomarker. The choice of the genetic variable as IV (Z) is essential to a successful in MR analysis. MR is named ‘Mendelian deconfounding’ as it gives to estimate of the causality free from biases due to confounding (C). To estimate unbiased estimation of the causality of the exposure (X) on the clinically relevant outcome (Y), Z has the 3 core assumptions (A1-A3). A1) Z is independent of C; A2) Z is associated with X; and A3) Z is independent of Y given X and C; The purpose of this review provides an overview of the MR analysis and is to explain that using an IV is proposed as an alternative statistical method to estimate causal effect of exposure and outcome under controlling for a confounder.

새로운 저온 열처리 공정으로 제조된 SrBi₂Ta₂O₉ 박막의 결정성 및 전기적 특성

We studied growth and characterization of $SrBi_2Ta_2O_9$ (SBT) thin films fabricated by low temperature process under vacuum and/or oxygen ambient. A metal organic decomposition (MOD) method based on a spin-on technique and annealing process using a rapid thermal annealing (RTA) method was used to prepare the SBT films. The crystallinity of a ferroelectric phase of SBT thin films is related to the oxygen partial pressure during RTA process. Under an oxygen partial pressure higher than 30 Torr, the crystallization temperature inducing the ferroelectric SBT phase can be lowered to $650^{\circ}C$. Those films annealed at $650^{\circ}C$ in vacuum and oxygen ambient showed good ferroelectric properties, that is, the memory window of 0.5~0.9 V at applied voltage of 3~7 V and the leakage current density of 1.80{\times}10^{-8}$ A/$\textrm{cm}^2$ at an applied voltage of 5V. In comparison with the SBT thin films prepared at 80$0^{\circ}C$ in $O_2$ ambient by furnace annealing process, the SBT thin films prepared at $650^{\circ}C$ in vacuum and oxygen ambient using the RTA process showed a good crystallization and electrical properties which would be able to apply to the virtul device fabrication precess.
