朴炅守 東亞大學校 大學院 1984 大學院論文集 Vol.8 No.1

Because the presidential election is one of the most crucial acts in American politics, the method of selecting the chief executive has been debated almost continuously since the electoral college was introduced in 1789. Today, few livelier issues face the America public than the proposal to abolish the electoral college and replace it with a form of direct voting for presidential candidates. This paper represents an attempt to analyze the existing electoral system and compares it with four leading alternatives, i.e., the direct vote, the automatic plan, the district plan, and the proportional plan. After studying the alternatives the author comes to the conclusion that the existing electoral college system best represents the American political tradition as well as its political system characterizing the American federalism.c

Infection is a major complication and potentially life-threatening in patients with acute leukemia. The patients require prompt broad-spectrum antibiotics therapy when fever develops. One of the keys to successful patient management is the recognition of institutional trends of the spectrum of infections and infecting microorganisms. So we evaluated 138 patients with acute leukemia and blastic crisis of chronic myelogenous leukemia admitted to Seoul National University Hospital from July 1986 to June 1992. The results are following: 1) Total number of febrile episodes was 224 and 60% of them occurred after chemotherapy. 2) Microbiologically-defined infection, clinically-defined infection, and unexplained fever accounted for 28%, 45%, 27% of the febrile episodes respectively. 3) Fifty-eight percent of microbiologically-defined infections were caused by gram-negative bactria, and 36% were gram-positive bacteria. There was a tendency to a greater proportion of gram (+) organisms than that of the last study (p>0.1). Escherichia coli was the most common organism, and coagulase-negative staphylococci, Pseudomonas aeruginosa, Klebsiella pneumoniae were common in decreasing order. 4) Pneumonia was the most common type of infection, followed by skin and soft tissue infection, perianal infection, gingivitis and primary septicemia. 5) Seventy-two percent of total infections improved with therapy and this success rate was higher than that of the last study(p<0.001).

박수경,김광휘 한국과학교육학회 2005 한국과학교육학회지 Vol.25 No.2

본 연구의 목적은 Sternberg의 정신자치제 이론에 근거하여 과학영재학교 재학생의 사고양식 유형과 학업성취 및 과학개념과의 관계를 밝히는 것이었다. 연구대상은 과학영재학교 1학년 120명과 일반계 남여 고등학교 2학년 122명이었다. 사고양식 검사도구는 정신자치제 이론을 근거로 13가지 사고양식을 측정하는 65문항의 자기 보고식 검사지이며 과목별 성취도는 과학영재학교와 해당 일반계 고등학교 중간고사와 기말고사의 총점을 사용하였다. 과학영재 학생의 사고양식 유형에 따른 과학 개념을 조사하기 위하여 TypeⅠ사고양식 집단과 TypeⅡ사고양식 집단 각 20명의 지구과학 개념검사 결과 응답을 분석하였다. 연구 결과, 과학영재학생은 일반학생에 비하여 입법적, 사법적, 무정부제, 전체적, 외부적, 그리고 진보적 사양식의 특성을 나타내어 새로운 과제를 선호하며 창의적인 방식으로 문제를 해결하는 경향을 보여주었다. 이는 본 연구대상 영재들이 학교 영재성의 특성을 가지는 동시에, 사고양식의 측면에서 볼 때는 창의적-생산적 영재성도 가지고 있는 것으로 해석된다. 사고양식과 학업성취의 관계는 영재학생의 경우 일반학생보다 사고양식과 교과 학업 성취의 상관 관계가 더 높게 나타났다. 이로써 과학영재와 일반학생의 학업성취의 차이가 부분적으로 사고양식의 차이에서 기인함을 알 수 있었다. 과학영재학생의 사고양식 유형별로 지구과학 개념을 조사한 결과, Type Ⅰ집단이 Type Ⅱ집단보다. 과학학습에 있어서 심층적 접근을 하는 것으로 나타났다. 학습활동이나 평가형태가 학습자들의 사고양식에 부합될 때 가장 높은 학업성취를 나타낼 수 있으므로 본 연구에서 밝혀진 사고양식 특성을 기초로 과학영재를 위한 학습 자료와 교수 전략의 개발 및 적용이 요구된다. On the basis of Sternberg's theory of mental self-government, this study examined the relationship between thinking styles and academic achievement of gifted science students and their earth science concepts by the different types of thinking styles. The participants were 120 students from the Busan Science Academy who were selected through the multi-step examinations for the school entrance. All participants responded to Sternberg's Thinking Styles Inventory which is a self-report test consisting of 65 items on 13 subscales, with a 5-point Likert-Type scale. In order to examine the gifted science students' earth science concepts by the types of thinking style, the responses in descriptive items for 40 students were analyzed . The results are as follows. First, gifted science students prefer the legislative, judicial, anarchic, global, external, and liberal styles, whereas. general students prefer the executive, oligarchic, and conservative styles. This result shows that gifted science students tend to not only exhibit schoolhouse giftedness but also creativeproductive giftedness. Second, gifted science students' academic achievement was more significantly correlated with the thinking styles than those of general students. Third. the Type Ⅰ thinking style group proved to process more complex concepts; on the other hand, the Type Ⅱ thinking style group proved to process simpler concepts in earth science. This indicates that Type Ⅰ thinking style students use deep learning approaches whereas Type Ⅱ thinking style students use surface learning approaches.

Q fever is a zoonosis caused by Coxiella burnetii, Presenting as acute and chronic illness and it has been reported worldwide. Acute Q fever is usually asymptomatic or mild and self-limiting, but infective endocarditis is one of the most serious complications of chronic Q fever and can be fatal. Known risk factors for Q fever endocarditis are valvular heart disease, immunocompromised hosts, and pregnancy. There have been some reports on Q fever in Korea but there exists no report on Q fever endocarditis. We have experienced 2 cases of Q fever with underlying valvular heart disease; both Patients came to the hospital for evaluation of prolonged fever. Although Q fever and Q fever endocarditis are rare in Korea, Q fever endocarditis should be considered in the differential diagnosis of patient with infective endocarditis when causative microorganism cannot be identified.

Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.
