본 연구에서는 입자 침전법으로 제작된 HgO와 PbO 기반 영상 센서의 유방촬영 영역에서의 적용 가능성을 조사하였다. 이를 위하여, 다양한 두께에 따른 HgO와 PbO 필름의 물리적 특성과 x선에 대한 양자 효율을 측정하였으며, 몬테카를로 시뮬레이션 결과와 비교 평가하였다. 또한, 입자 침강법을 이용하여 인듐 주석 산화물로 코팅 된 투명 유리기판 위에 대면적 다결정 박막을 제작하였다. 본 연구에서는 단결정의 효율과 비슷한 양자 효율을 얻기 위하여 필름의 두께와 제작 조건을 변화시켜 최적화 하였다. 본 연구의 결과를 기반으로 차후 대면적 a-Si:H 패널에 적합한 대면적 필름의 제작 기술과 최적화 연구가 가능할 것으로 판단된다.

Globally, as well as domestically, patients without risk factors for spontaneous spinal epidural hematoma (SSEH) have rarely been reported. SSEH often results from trauma, epidural catheter insertion for anesthesia and invasive spinal procedures. It could also occur in patients with risk factors such as hypertension, coagulopathy, pregnancy, and vascular anomaly. We encountered a case of a 51-year-old female without prior medical history or any risk factors. Magnetic resonance imaging (MRI) showed subacute SSEH at lumbar spine regions. The patient was treated successfully by surgical decompression. Therefore, we report this case with a review of the relevant literature.

Treatment of spontaneous retroperitoneal hemorrhage (SRH) is mainly conservative. However, if intra-abdominal hypertension (IAH) or abdominal compartment syndrome (ACS) develops, the treatment strategy should be more aggressive. Surgical decompression has been the gold standard; however, it is very invasive and highly morbid. Thus, percutaneous catheter drainage (PCD) has been introduced as an alternative therapeutic option. We report on a case of successful PCD for prevention of progression of IAH to ACS in a patient with SRH after coronary stent implantation. This case showed that PCD can be an efficacious and safe method for treatment of IAH with impending ACS.

Recently there are increasing numbers of people participating in sports activities. Accordingly, the rate of sports injuries is increasing as well. In this light, this study was conducted to investigate the extent of acute damage and its forms by examining the current state of patients with sports injuries. This research study was conducted between January of 2008 and December of 2010 in Chosun University Hospital through retrospective review of the medical records of patients with sportsrelated injuries. The total number of patients with sports injuries who visited the emergency center was 887. The number of male patients was 726 (81.85%), far more than the number of female patients (18.15%). More than half of the patients, accounting for 419 (47.23%), had injuries on their face; second and common parts, in which injuries occurred, were upper and lower body, accounting for 146 (16.45%) and 193 (21.75%), respectively. The majority of patients did not undergo surgical treatment. Only 113 (12.73%) patients underwent surgical treatment. In addition, more than 80% of them were not hospitalized but 170 of them needed to be hospitalized. Most sports injuries occurred in young male patients. This can interrupt participation in sports activities for a long time and result in lower quality of life. Hence proper preventative measures and scientific treatment methods are needed.

초고령화된 한국 농촌에서 다양한 교육 및 직업 배경을 가진 중장년층 귀농인구의 유입은 고령화 문제에 대한 대안의 하나로 부각되고 있다. 본 연구는 농가 고령화에 대한 귀농인구의 잠재적인 기여도 측면에서 귀농인구의 지역별 유입 유출 패턴을 분석하였다. 분석에는 로그선형모형과 총합레퍼런스코딩을 사용하였고, 분석자료는 통계청의 2013년 귀농 통계이다. 분석결과에 의하면, 귀농인의 절반 정도가 수도권에서 비수도권 지역으로 이주한 인구이고, 이들을 제외하면 귀농인의 대부분은 원 거주지가 있던 도 내에서 이동하고 있다. 귀농인의 귀농 전 대비 귀농 후 지역 내 오즈비(odds ratio)는 지역별로 차이가 있으며, 귀농인의 성별과 연령에 따라서도 지역별 유입 유출패턴이 다르다. 이는 귀농인 유입의 긍정적 효과를 높이기 위해서는 지자체별 차이를 반영한 특화된 정책이 필요하다는 것을 의미한다.

This study aimed to evaluate the role of D-dimer in terminal cancer patients. Among 343 incurable cancer patients, only 4 patients (2.8%) had normal D-dimer levels, and the majority (n=115, 81.0%) had levels >2.0 μg/mL. The survival time was significantly differed according to D-dimer levels with a median of 48 days when D-dimer levels were <2 μg/mL and 19 days when D-dimer levels were higher. D-dimer levels were negatively correlated with survival according to Spearman’s rank correlation analysis (coefficient -0.335, p<0.001). In terminal cancer patients, D-dimer concentrations did exhibit prog-nostic significance.

Water quality of the Koejong-reservoir was estimated by using the ecological model to evaluate the effects of industrial sewage discharge. State variables consist of POC, DOC, phytoplankton, DIP, DIN, DO and COD. Initial conditions for the compartment are applied to the model based on the observed results. The reproducibility was found to be satisfactory with the relative error ranging between the calculated value and the observed value. Water quality simulation was conducted by applying additional industrial sewage discharge into the Koejong-reservoir. The concentrations of COD, Chl.a, DIP and COD showed fluctuations of a narrow range. The increment percentages of Chl.a, COD and DIP were 26.6%, 20.2% and 18.2%, respectively. In the case of DO, the concentration decreased 4.8%.

Purpose ‒ This study aims to analyze changes in attitudes towards women's political leadership and the social factors related to such changes. The study reviews the field of women's political leadership, specifically the political and economic participation of women in the world, and the impact of variables such as the changes in attitude on such participation. Research design, data, and methodology ‒ The population for this study comprises 99 countries that are members of the United Nations and have participated in the third and fifth waves of the World Values S urveys. The sample consists of 31 such countries selected for sampling. Results ‒ This study is a secondary analysis to examine the hypotheses regression and the LISREL model are used. The findings of the study indicate that the correlation between two variables, namely women's political participation and leadership of women, is statistically significant. Conclusions ‒ The changing rate of women's economic participation is also significant. The significance of these coefficients indicates that the results, with a 95% confidence level, can be extended to all member states.
