Purpose: To attain improvement in prognosis of patients suffering acute ischemic strokes (AIS), it is crucial to diagnose these swiftly and accurately. It is generally believed that female patients have a less favorable outcome, but there has not yet been sufficient data to confirm this opinion. The authors herein conducted a study to determine whether the symptoms of AIS differ between males and females. Methods: A retrospective study was conducted on 322 consecutive patients who were diagnosed with AIS on the basis of MRI findings during the last two years. Demographic findings and clinical features were collected from emergency room records in order to evaluate gender differences. Results: There were 148 female patients (45.8% of total) in our study, and the average age of affection for females was significantly higher than males. Our data did not achieve statistical significance; however, we observed the following tendencies: the time from symptom onset to admission was delayed in female group; both traditional and nontraditional symptoms were more prevalent in the male group; and atypical symptoms were observed in the female group. Conclusion: No gender difference was observed in the incidence of acute ischemic stroke. However, the proportion of atypical symptoms was relatively higher in female patients. Factors resulting in delay clinical attention and contributing to the observed discrepancy between genders in AIS diagnosis should be validated and investigated further.

21세기 지식 기반, 정보화 기반 사회는 수학을 단순히 적용하는 능력이 아닌 실생활이나 다른 교과 영역에서 수학적 지식을 사용하여 문제를 구성하고 해결하는 문제 해결력 등의 수학적 힘(Mathematical power)을 필요로 한다. 수학적 힘을 기르기 위해서는 수학의 기본 지식, 추론 능력, 문제 해결력, 수학적 아이디어의 표현 및 교환능력, 그리고 사고의 유연함, 인내, 흥미, 지적 호기심, 창의력을 길러 주는 다양한 교수 학습 방법이 필요하다. 본 연구에서는 다양한 학습 매체를 이용한 실생활 중심의 교수 학습 지도안을 개발하고 이를 통하여 학생들의 수업에 대한 반응과 수학에 대한 인식 변화를 분석하였다.

Posterior reversible encephalopathy syndrome (PRES) is typically characterized by headache, altered mental functioning, seizure, and visual loss associated with imaging findings of bilateral subcortical and cortical edema with a predominantly posterior distribution. The usual causes of PRES are hypertensive encephalopathy, preeclampsia, eclampsia, cyclosporine A neurotoxicity and uremic encephalopathy. Early recognition of PRES is important because the treatment of PRES can be relatively contraindicated in some conditions, such as cerebral ischemia. We describe a 28-year-old woman who presented with a seizure 11 days after delivery. The diagnosis of PRES was made later. To make an early diagnosis of PRES, the emergency physician should include PRES in the differential diagnosis and consider an MRI with diffusion-weighted imaging in patients presenting with seizure, altered mental status, headache, and visual loss, especially patients with a hypertensive crisis, an organ transplantation, or a history of recent delivery.
