서 론: 본 연구는 주의력결핍 과잉행동장애(이하 ADHD) 아동과 정상대조군의 연속수행검사(이하CPT) 결과 양상을 비교하여 CPT의 진단적 유용성을 알아보고자 하였다. 그리고, ADHD 아동의 연령과 성별, 지능, 그리고, 장애의 유형 등과 같은 변수에 따른 CPT의 결과양상을 비교하여, CPT가 ADHD의 어떤 특성을 잘 반영해주는가를 알아보고자 하였다. 대상 및 방법: DSM-Ⅳ의 진단기준에 의하여 진단이 내려진 ADHD 실험군 68명과 정상대조군 30명을 선정하였으며, 두 군간의 연령과 성별을 통제하였다. 실험군과 정상대조군 모두 환아의 부모가 ADHD 평가척도(ADDES-HV)를 작성하였으며, 환아에게 직접 CPT를 실시하였고 지적 능력을 평가하기 위해 K-ABC를 시행하였다. 결 과: 실험군과 정상대조군에서의 CPT 결과 양상을 비교하였을 때, 실험군과 정상대조군 사이에 민감도가 유의한 차이를 나타내었고, 반응 기준도 유의한 차이를 나타내었다(p<0.05). ADHD 아동을 대상으로 연령과 지능의 변화에 따른 CPT의 결과 양상을 비교하였을 때, 연령과 지능이 증가함에 따라 CPT각각의 결과들도 대체로 수행력이 호전되는 경향을 나타내었다. 주의력결핍 과잉행동 장애의 유형을 과잉행동을 동반한 군과 과잉행동을 동반하지 않은 군으로 나누어 비교분석을 한 결과, CPT 각각의 결과에서 유의한 차이는 나타나지 않았다. CPT 결과 양상에 있어서 남녀간 차이점을 비교하였을 때, 오경보오류와 정반응시간의 표준편차, 표준편차의 다양성, 그리고, 민감도가 유의한 차이를 나타내었다(p<0.05). CPT 각각의 8가지 결과 변수들에 대해 판별분석을 실시한 결과, 각각의 결과 변수들에 있어서 진단에 대한 전체 판별력이 모두 50%이상을 나타내었다. 그 중, 정반응시간의 표준편차와 표준편차의 다양성, 그리고, 민감도는 진단에 대한 전체 판별력이 모두 60%이상을 나타내었다. 결론 및 고찰: 이러한 결과들은 CPT가 ADHD의 진단에 있어서 어느 정도의 유용성을 가지고 있다는 점을 보여준다 하겠다. 즉, ADHD에 있어서 CPT는 비교적 선별검사와 같은 목적으로는 유용할 것으로 생각되며, 이는 또한 CPT가 장애의 진단에 있어서 보조적인 검사도구임을 나타낸다 하겠다. Objectives: The purpose of this study was to examine to diagnostic availability of CPT in children with ADHD, and what factors are affected to CPT results in the diagnosis of ADHD. Method: CPT, ADHD scales(ADDES-HV), K-ABC were administered to 68 ADHD patients and 30 normal elementary school students as the control group. Also, ages and sex are controlled between two groups. Results: In the differences of the results of CPT between ADHD patients and normal subjects, attentiveness and risk taking are significantly different(p<0.05). In the differences of the results of CPT between ages in ADHD patients, usually as more aged children are better performances in CPT. Also, in the differences of the results of CPT between intelligence in ADHD patients, usually as higher intelligent children are better performances in CPT. There are no differences of the results of CPT between types of ADHD in ADHD patients. In the differences of the results of CPT between sex in ADHD patients, commission error, hit reaction time standard error, variability of standard error, and attentiveness are significantly different between male and female patients(p<0.05). The correlations between ADHD scales and the results of CPT show that inattention subscale is significantly related to hit, omission error, hit reaction time standard error, and variability of standard error. In the discriminant ability between ADHD patients and normal children by the results of CPT, accuracy rates are more than 50% in all results of CPT. Especially, the accuracy rate of hit reaction time standard error, and the accuracy rate of variability of standard error, and also, the accuracy rate attentiveness are more than 60%. Conclusion: In this point of view, this study suggest that CPT is relatively valuable method in the diagnosis of ADHD. For instances, CPT is more likely to screen the ADHD from normal children, or to use as assisted method of diagnosis of ADHD in clinical settings.

The purpose of this experimental thesis is to distinguish the differences in the way they produce vowel sound between Korean learners of English and English native speakers through acoustic phonetical experiment. To find out the distinctive features of English vowels that Americans and Koreans Pronounce, formant frequencies in spectrograph were measured. For the experiment. 3 Americans and 6 Koreans recorded their vowel pronunciation in sentences with minimal pairs. The result shows that Koreans usually move their tongue not as wide as Americans do. This may have caused by the language transfer. Moreover Americans pronounce back vowels longer while Koreans make front vowel sound longer. The reason for that is Americans use their tongue root more actively than Koreans.

The authors present six cases of lateral ventricle meningiomas treated at Seoul National University Hospital between 1979 and 1991. These six cases of lateral ventricular meningiomas constitute 1.8 percent of all intracranial meningiomas and 16.7 percent of mass lesions of the lateral ventricle. The mean age was 29 years ranging from 11 to 50 years, younger than that or intracranial meningiomas with a statistical significance(p<0.01). Four of the patients were women and two were men. All cases were located in the trigonal area. The most common clinical symptoms and signs were related to increased intracranial pressure such as headache, nausea and vomiting. Based on the clinical presentation and radiological features(CT. MRI and angiography), correct preoperative diagnosis was possible in five cases. Gross total removal of the tumor was achieved in all cases. There was no operative mortality. A temporal gyrus approach was used in five cases with good surgical results. The benefits and drawbacks of each surgical approach for meningiomas of the lateral ventricle is discussed with review of pertinent literatures.

Background and aims : In the coronary artery disease, a rate of restenosis was much decreased by placement of coronary stent than when percutaneous transluminal coronary angioplasty has been applied, but there are still important clinical problems of restenosis. There has been many progressive studies about various factors contributed to this restenosis. So, we studied a relation between restenosis after placement of coronary stent in the coronary artery disease and many clinical factors, characteristics of stenotic lesion and procedural factors, and also assessed the restenosis rate of various coronary stents. Methods : Total 58 lesions(46 cases of patients ; man 30, woman 16) were evaluated, which has been performed a follow-up coronary angiography after 6 months (mean 188 days) since coronary stent had been placed. Various stents were implanted and assessed a relation between restenosis and many factors. Results : Of 58 lesions were target stenotic studies, there were 22 of restenotic lesions(37.9%), and the restenosis rate wes statistically significant difference in the relation with diabetes mellitus(p<0.05), group of acute myocardial infarction(p<0.05) among clinical diagnosis of ischemic heart disease(stable angina, unstable angina and acute myocardial infarction) in clinical factors and with high dilation pressure of stent(p<0.05) in procedural factors. When the rate of restenosis was evaluated among implanted stents, it was lowest in the Multilink^(®) stent and highest in the Nir Royal^(®) stent(60%). Conclusion : In this study of restenosis and various factors after placement of stents in the coronary artety disease, factors such as diabetes mellitus, group of acute myocardial infarction and a dilation pressure of stent were significant related with restenosis and the restenosis rate of Multilink^(®) stent was lowest and the highest restenosis rate was of Nir Royal^(®) stent.

This study is aimed at proposing the specific plans to use history drama lessons through the study on the relations between reality, fascination and involvement that are sub-variables of history drama viewing and middles school students’ historical consciousness, and to raise their historical consciousness by using history drama lessons. In order to accomplish such a goal, the study selected respective 250 middle school students in Daegue and Gumi, Gyeongsangbuk-do as its subjects, and the surveyed and analyzed findings are obtained as follows. First, it is the result obtained by dividing the subjects’ general characteristics. Fascination and involvement among reality, fascination, and involvement that were sub-variables had a difference in the division by sex. Fascination was shown to be higher in female students while involvement was higher in male students. In addition, as to the region, history drama viewing had no difference in middle school students of Daegue and Gyeongsangbuk-do. Historical consciousness was higher in middle school students of Daegue that those of Gyeongsangbuk-do, while regarding the grade there was no difference in history drama viewing and historical consciousness. Second, it was the result regarding how reality, fascination, and involvement that were sub-variables of history dram viewing affected historical consciousness. With regards to types of history dram viewing, fascination, reality, and involvement significantly affected historical consciousness in order. According to the gender, male students’ reality, involvement, and fascination gave a significant effect on historical consciousness while female students’ involvement didn’t affect historical consciousness, and fascination and reality gave an effect on historical consciousness in order. As to the grade, the first graders’ reality, fascination, and involvement were not related to historical consciousness while the second graders’ reality and fascination except for involvement affected in order. Besides, the third graders’ fascination only affected historical consciousness. Regarding the region, fascination and reality of middle school students in Daegu affected historical consciousness in order while fascination, involvement, and reality of middle school students in Gyeongsangbuk-do influenced historical consciousness. Like this, there was a little difference in the gender, grade, and region, but reality, fascination, and involvement that were sub-variables related to history drama viewing affected historical consciousness, and the higher sub-variables related to history drama viewing were, the higher historical consciousness was. Due to the fact that history dramas had a fictional element, there was a discussion on educational efficiency. However, this study verified the fact that history dramas can be educationally used, instead of deciding whether history drams were true or not. Based on the findings of the study, the effective utilization methods of history dramas in history lessons are suggested as follows. First, the study of historical figures using history dramas is possible. Students can understand properties of characters through re-enactment and empathy, and approach various figures that don’t appear in textbooks. Second, they can raise critical view that is able to divide false and fact of history dramas and use it to the fact learning. Third, it is possible to learn historical terms. By learning unfamiliar and difficult historical terms in advance, they can increase interest in history lessons. Fourth, storytelling of historical materials is possible. Students can make their own new interpretation by constructing various historical materials in a way of history dramas. Fifth, they can use a decoration making of history dramas, a visiting of the set, and a clipping of TV screen capture in various manufacturing studies as materials. Sixth, they can have a mock trial and a role-playing lesson regarding behaviors decisions of history drama figures. Seventh, they can study the public life history through history dramas. 이 논문은 중학생의 역사 드라마 시청이 역사의식에 미치는 영향에 대한 것이다. 역사 드라마 시청과 관련된 하위변인인 현실감, 심취도, 관여도는 성별, 학년, 지역에 따른 차이는 있지만, 역사의식에 분명 히 영향을 미치고 있다. 영향력의 크기는 심취도, 현실감, 관여도 순으로 나타났다. 그렇기에 역사 드라 마 시청과 관련한 역사 수업은 중학생의 역사의식 향상에 도움을 줄 수 있을 것으로 보인다. 역사 드라마를 시청하려는 의도와 시청하는 동안의 관여도 정도는 남학생의 경우 역사의식에 유의한 영향을 미쳤지만, 여학생의 경우 유의한 영향을 미치지 않는 것으로 나왔다. 학년별로 결과를 살펴보면 모든 학년에서 관여도는 역사의식에 통계적으로 유의한 영향을 주지 않는 것으로 나타났고, 제일 고학 년인 3학년에서 심취도만이 영향을 주는 것으로 보아 역사 드라마를 시청함에 있어 역사적 사실과 허구를 구별하는 능력이 아래 학년보다 발달하여 현실감의 영향을 덜 받은 것으로 보인다. 역사의식은 대구광역시 중학생이 경상북도 중학생보다 다소 높다. 그리고 실제 사극의 선호도는 퓨전 이나 판타지를 선호하지만 실제 전통사극이 역사의식에 더 높은 영향을 미쳤다. 이것은 현장 교사의 경 험담과 일치한다.

This paper shows experimentally that oxide layer on the p-type Si-substrate can grow at low temperature(500℃∼600℃) using high pressure water vapor system. As the result of experiment, oxide layer growth rate is about 0.19Å/min at 500℃, 0.43Å/min at 550℃, 1.2Å/min at 600℃ respectively. So, we know oxide layer growth follows reaction-controlled mechanism in given temperature range. Consequently, granting that oxide layer growth rate increases linearly to temperature over 600℃, we can expect oxide growth rate is 5.2Å/min at 1000℃. High pressure oxidation of silicon is particularly attractive for the thick oxidation of power MOSFET, because thermal oxide layers can grow at relatively low temperature in run times comparable to typical high-temperature. 1 atm conditions. In the condition of higher-temperature and high-pressure steam oxidation. the oxidation time is reduced significantly.
