In Korea, a seismic evaluation method is not established systematically. Though There is a little chance to experience strong earthquake, it is not negligible. The purpose of this theme is to introduce a seismic evaluation method suggested by FEMA 273 and to apply it to buildings in Korea. In this study, non-linear static analysis with DRAIN-2DX is performed to evaluate the capacity of structural building at target displacement.

Background: Maternal obesity is a well-known risk factor for both total preterm birth (PTB) and spontaneous PTB in singleton gestation, whereas this association is not well determined in multiple pregnancy. The objective of this study was to determine the risk of spontaneous PTB according to the pre-pregnancy body mass index (BMI) in twin gestations. Methods: The association between the risk of PTB and pre-pregnancy BMI was determined in women pregnant with twins between 2004 and 2014. Pre-pregnancy BMI values were divided into three groups (underweight/normal/overweight and obese). PTB was classified as spontaneous PTB (following preterm premature rupture of membranes, preterm labor, or cervical insufficiency) or medically indicated PTB (cesarean section or induction of labor because of maternal/fetal indications). Results: A total of 1,959 women were included in the analysis, and the percentages of total PTB and spontaneous PTB were 13.1% and 9.3%. The percentages of total PTB and spontaneous PTB in three groups were 14.1%, 11.9%, 16.3%, respectively, and 11.0%, 8.0%, 12.5% (P < 0.05 between normal and overweight/obese women). The risks of total and spontaneous PTB in overweight/obese women were higher than those in women with normal weight, even after adjustment for prior history of PTB, age, maternal height, parity, in vitro fertilization-embryo transfer (IVF-ET) (odds ratio [OR], 1.43; 95% confidence interval [CI], 1.01–2.03; OR, 1.58; 95% CI, 1.05–2.36). Conclusion: The risks of both total and spontaneous PTB were significantly greater in the overweight/obese group than in the normal BMI group.

In this paper, we propose an algorithm both geometric correction using a grid point image and radiometric adaptive projection that dependent upon the luminance of the input image and that of the background. This method projects and captures the grid point image then calculates the geometrically corrected position by difference between the two images. Next, to compensate color, a corrected image is calculated by the ratio divided luminance of an input image by luminance of arbitrary surface. In addition, we found the scaling factor which controls the contrast to avoid clipping error. At this time, the scaling factor is dependent on mean image lightness when background is determined. Experimental results show that the proposed method achieves good performance and is able to reduce the perceived color clipping and artifacts, better approximating the projection on a white screen. 본 논문에서는 보정 영상을 프로젝터가 표현할 수 있는 범위로 콘트라스트(contrast)를 조절하여 주는 요소(scaling factor)를 적용하여 색 보정영상을 획득하는 방법을 제안한다. 이 조절 요소는 입력영상과 사용된 표면의 평균 밝기를 이용하여 계산하였다. 또한 사용된 프로젝터 및 카메라의 특성화 과정에서 오는 오차와 부정확성을 해결하기 위하여 프로젝터와 카메라 양단간의 관계를 적용한다. 실험 결과에서 제안한 색 보정 방법이 임의의 표면으로 입력된 다양한 영상에 대하여 밝기를 유지하면서 클리핑 결함은 감소되어 화질이 개선된 것을 확인하였다.

Purpose:This study was undertaken to find out a useful method that can predict the true leukocytosis in blood-contaminated cerebrospinal fluid(CSF) due to traumatic lumbar puncture(LP), using white and red cell counts of sanguineous CSF and peripheral blood. Methods:From May 2001 to December 2002, among 1,247 patients presenting symptoms of meningitis who had received LP at Chonnam Hospital, 126 patients were included in this study who had undergone a second LP due to a traumatic first one. According to the final results of second LP, they were devided into two groups, aseptic meningitis group; and normal CSF group. Medical records were reviewed retrospectively, the proportions of white blood cells to red blood cells were obtained in the peripheral blood(WBC:RBCBlood) and CSF(WBC:RBCCSF), based on the results of the traumatic first LP and simultaneously performed peripheral blood count. The WBC:RBCCSF/WBC:RBCBlood ratio was calculated in each patient. Results:The WBC:RBCCSF/WBC:RBCBlood of the normal CSF group was 13.5±7.3(standard deviation), significantly lower than 47.3±39.5 of the aseptic meningitis group. Conclusion:The WBC:RBCCSF/WBC:RBCBlood is a useful value to predict frank leukocytosis in the blood-contaminated CSF due to traumatic LP, but all clinical and laboratory informations must be considered before deciding on a treatment strategy to minimize the risk of misdiagnosis. 목 적 : 무균성 뇌막염 환아의 혈성 요추천자액에서 뇌척수액의 백혈구 증가를 예측하는데 있어서 WBC : RBCCSF/WBC : RBCBlood 값의 유용성을 연구하였다.방 법 : 2001년 5월에서 2002년 12월까지 본원에서 요추천자를 시행받은 환아들 중에서 첫 번째 요추천자에서 혈성을 보여 두 번째 요추천자를 시행해 비혈성의 뇌척수액에서 정확한 백혈구수를 알 수 있었던 126명을 대상으로, 두 번째 요추천자에서 백혈구 증가가 있었던 105명을 무균성 뇌막염군으로, 그렇지 않았던 21명을 정상 뇌척수액군으로 나누어 각 군의 혈성 천자 당시의 말초혈액 검사와 혈성 뇌척수액의 백혈구와 적혈구의 수를 토대로 WBC : RBCCSF/WBC : RBCBlood 값을 구하였다.결 과 : 정상 뇌척수액군의 WBC : RBCCSF/WBC : RBCBlood 값은 13.5±7.3으로 무균성 뇌막염군의 47.3±39.5에 비해 유의하게 낮았다.
