이정화(Lee Joung-Hwa),이정은(Lee Jung-Eun) 한국열린유아교육학회 2002 열린유아교육연구 Vol.6 No.4

본 연구는 유치원과 초등학교 저학년 교사들의 유아과학교육에 대한 인석 및 실태를 비교, 조사하여 현행 유아과학교육의 목적, 내용, 방법, 평가 면에서의 문제점을 파악하고 이의 해결방안 및 개선점을 탐색하고자 실시되었다. 연구 결과, 암 기관 교사들은 유아과학교육의 목적이 과학적 소양의 함양임을 바르게 인식하고 있는 것으로 파악되었다. 그러나 내용 면에서는 유치원 및 초등학교 저학년간에 서로 다른 경향으로 유아과학교육의 내용들이 균형있게 실시되지 못하고 있는 것으로 나타났다. 방법 면에서는 통합적인 교육방법 및 효율적 지도를 위해서 해결해야할 과제가 양 기관간에 서로 다르게 드러났다. 그리고 평가 면에서는 양 기관 모두 평가영역 및 평가방법의 다양성을 강조할 필요가 제기되었다. The purpose of this study was to investigate the practice of science education of the kindergartens and the lower grade elementary schools. The subjects of this study were the 108 kindergarten teachers and the 142 lower grade elementary school teachers in Pusan. The questionnaire was made by modifying a questionnaire used on preceding research. It consisted of four categories ; aim, contents, methods, and evaluation of science education for young children. The data was analyzed using SPSS/PC? to compute frequency and percentile. The results of this study were summarized as follows ; First, the lower grade school teachers recognized the importance of science education more deeply than the kindergarten teachers. Both the kindergarten teachers and the lower grade teachers consider the purpose of science education as motivating children to have curiosity and interest in surrounding objects and natures. Second, the main contents of science education at both the kindergartens and the lower grade elementary schools were 'living things', 'physical phenomena & changes', and 'sense activity'. However, it was revealed that 'chemical phenomena & changes' and 'earth environment' were little taught in the kindergartens and lower grade elementary schools respectively. Third, the teaching methods of the science education at the kindergartens and the lower grade elementary schools were different in many aspects. Forth, both the kindergarten teachers and the lower grade elementary school teachers evaluated children's achievement very often through observing their children. It was suggested that the both teachers need to evaluate their teaching methods and program for their children more often.

목적: 숙변대장염은 대장에 분변이 꽉 채워져 장관 내 압력이 증가되고 이와 관련되어 장벽의 허혈 및 압력 괴사를 초래하여 발생하는 대장염이다. 숙변대장염은 드문 질환으로 예후가 불량하다. 저자들은 숙변대장염의 임상적 특징과 치료 전략에 따른 결과를 알아보고자 한다. 방법: 2004년 1월부터 2009년 8월까지 본원에서 CT검사와 대장내시경 검사를 통해 숙변대장염으로 진단된 11명의 환자를 대상으로 하여 후향적 연구를 하였다. 대상환자들의 임상적 특징을 조사하고 수술적 치료와 보존적인 치료에 따른 임상적 결과를 조사하였다. SIRS, 패혈증 혹은 패혈성 쇼크가 동반된 경우를 중한 숙변대장염이라 정의하였다. 결과: 총 11명의 환자가 포함되었으며 이들 중 3명이 남자였고, 8명은 여자였다. 평균 연령은 70±8세였다. 10명의 환자들은 변비의 유발요인들을 갖고 있는 고령의 환자였다. 저자들의 정의에 의해 9명의 환자가 심한 숙변대장염으로 진단되었고, 이들 중 5명은 수술적인 치료를 받았으며 나머지 4명은 보존적인 치료를 받았다. 수술적 치료를 받은 5명 중 1명(20%)이 사망하였고, 보존적인 치료를 받은 환자(n=4)들은 모두 사망하였다. 결론: 만성 변비의 유발요인을 갖는 고령의 환자가 복통을 호소하고 CT상에서 분변박힘 소견과 함께 대장 벽의 국소적인 비후가 관찰되거나 장 주위 지방침윤이 동반되면 숙변대장 염의 가능성을 고려하여야 한다. 더욱이 환자가 SIRS, 패혈증 혹은 패혈성 쇼크가 합병된 중한 숙변대장염으로 진단된 경우라면 조기의 수술적 치료가 사망률을 감소시킬 것으로 생각된다. Background/Aims: Stercoral colitis is an inflammatory condition related to increased intraluminal pressure, itself caused by impacted fecal material. Stercoral colitis is a rare condition and has a generally poor prognosis. The aims of this study were to investigate the clinical characteristics and outcomes of stercoral colitis according to management strategy. Methods: From January 2004 to August 2009, 11 patients were diagnosed with stercoral colitis at our center. The medical records of these individuals were reviewed retrospectively with regard to the clinical characteristics, management strategy, and clinical outcomes. We defined severe stercoral colitis as stercoral colitis complicated by systemic inflammatory response syndrome, sepsis, or septic shock. Results: Eleven patients (three men and eight women) with a mean age of 70±8 years were included. Ten patients were elderly with constipation as a predisposing factor. Nine patients had severe stercoral colitis according to out criteria. Of these, five patients underwent surgery, and the other four were treated with a conservative management strategy. One patient (20%) in the surgical group and all patients in the conservative management group (n=4) died. Conclusions: Stercoral colitis should be considered in elderly patients with predisposing factors and presents as fecal impaction with colonic wall thickening or pericolic fat stranding on CT scan. In patients with severe stercoral colitis, early surgery may be effective in reducing mortality. (Korean J Med 2011;80:187-192)

Scrub typhus is an acute febrile illness that results from the destruction of endothelial cells by Orientia tsutsugamushi and subsequent systemic vasculitis. It manifests as fever, headache, myalgia, eschar formation, and lymphadenopathy. Some authors have reported that such vasculitis involves the gastrointestinal tract and that hyperemia, erosion, ulceration, and active bleeding of the gastric mucosa subsequently develop. However, no case of ulcer perforation in a patient with scrub typhus has been reported to date. Here, we report the case of a perforated duodenal ulcer in a 70-year-old female patient with scrub typhus. (Korean J Med 2012;82:449-452)

수막암종증은 암세포가 뇌수막에 침윤한 상태로 정의하는데 자기공명영상이 진단방법으로 쓰이기 전까지 진단이 용이하지 않았다. 또한 전립선암 환자에서 수막암종증이 생긴 경우는 매우 희귀하여 증례보고 형식으로 소수에서 보고 되고 있는 실정이다. 내원 11년 전 전립선암으로 근치적 전립선 절제술을 받고 내원 4년 전 골전이로 항암치료를 받은 병력이 있는 환자로 경련을 주소로 내원하여 시행한 반복적인 뇌척수액 검사에서 세포진을 발견하지 못했지만 뇌척수 액 전립선 특이항원 양성소견과 뇌 자기공명영상 소견으로 수막암종증을 진단하고 조직검사를 통해 확진하여 적극적인 치료로 생명연장을 할 수 있었던 사례를 경험하였기에 문헌 고찰과 함께 보고한다. Meningeal carcinomatosis in patients with prostate cancer is very rare. Recently, we experienced a case of meningeal carcinomatosis in a patient with prostate cancer. He had undergone a radical prostatectomy 11 years before presentation and had undergone chemotherapy 4 years before presentation due to bone metastases. This time, he visited the emergency department because of a seizure. Although cerebrospinal fluid (CSF) examinations did not reveal malignant cells, we diagnosed meningeal carcinomatosis based on positive CSF prostate-specific antigen and magnetic resonance imaging (MRI) findings. The diagnosis was confirmed pathologically. We treated the patient with whole brain radiotherapy and intrathecal chemotherapy. We report a case of prostate cancer with meningeal carcinomatosis with a literature review. (Korean J Med 2011;81:262-265)
