The incidence of superior cerebellar artery aneurysm is less than 1% of all intracranial aneurysms. These aneurysms usually occur at the junction between the superior cerebellar artery and the basilar trunk, however, seldom occur distally. We present a extremely rare case of distal superior cerebellar artery aneurysm arising at the junction between anterior pontine segment and ambient segment.

정재은,양근혁,윤현섭,Jeong, Jae-Eun,Yang, Keun-Hyeok,Yoon, Hyun-Sub 한국건설순환자원학회 2015 한국건설순환자원학회 논문집 Vol.3 No.2

본 연구에서는 박테리아를 활용하여 콘크리트 구조체를 코팅할 수 있는 기초 기술을 개발하는데 중점을 두었다. 박테리아의 자기정화 능력과 함께 콘크리트 내구성 향상을 함께 도모하기 위하여 슬라임 막을 형성하는 박테리아(Rhodobater capsulatus)를 선정하고 이를 흡착하기 위한 기술을 제시하였다. Rhodobater capsulatus의 배지별 슬라임 생성량 및 생장속도 평가결과로부터 최적의 배지조건은 maltose로 평가되었다. 제시된 배지를 기반으로 배양된 Rhodobater capsulatus의 고정화를 위해 흡착제를 활용하였으며 이를 image analysis 통해 흡착특성을 평가하였다. Rhodobater capsulatus 흡착을 위해서는 고 다공성 수지가 추천될 수 있었다. This study focused on the development of a fundamental technology for coating of concrete surface using slime produced from bacteria. To assign self-purification ability and improve durability performance of concrete, Rhodobater capsulatus that generates slime were selected and absorption technology for the selected bacteria was then examined. From the production of slime and growth activity of the bacteria, the optimum medium for Rhodobater capsulatus can be recommended as maltose. Furthermore, image analysis showed that high porous resin powder is more effective for absorption of the Rhodobater capsulatus than the other materials tested.

Objectives : A 10-year retrospective clinical study was undertaken to determine the differences between two groups according to age at presentation(group A, under 50 ; B, over 50). Methods : We analyzed 468 cases with chronic subdural hematoma admitted to the department of neurosurgery in our hospital from January 1987 to December 1996. The patients were divided into two groups according to age at presentation(group A, under 50 ; B, over 50). Results : 1) The number of group A was 126 cases(26.9%) and that of group B was 342 cases(73.1%), respectively. Males were more frequently involved than females in each group. 2) There noted a history of head trauma in 88.9% of group A and 92.4% of group B. Forty-nine patients(38.9%) of group A and 103 cases(30.1%) of group B revealed a history of alcoholism. 3) Group A patients presented with symptoms of increased intracranial pressure such as headache(75.% ), nausea and vomiting(68.0%). However, Group B patients had more frequent mental changes(84.0%) and focal neurological deficits such as hemiparesis(76.5%). 4) Onset of symptom and its duration was shorter in group A than group B. 5) Six patients among 441 cases(1.4%) treated with burr hole drainage and two patients of 27 cases(5.4%) with craniotomy died, and all of these were group B patients. The two cases among six patients with burr hole drainage developed huge intracerebral hemorrhage and brain stem hemorrhage, respectively. Conclusion : In treating patients with chronic subdural hematoma, distinguishing between two age groups is quite helpful to determine treatment strategies.

20대 남성의 실제체형과 신체이상형(理想型)에 관한 연구

정재은,이순원,Jeong, Jae-Eun,Lee, Sun-Won 대한인간공학회 1998 大韓人間工學會誌 Vol.17 No.2

The purpose of this study is to study real body size and ideal body shape by considering the degree of satisfaction of body part and understanding body size by the degree of leanness/obesity. The subjects in this study were 420 males from 18 to 25 years old. Body measurements and surveys were taken and analyzed by mean, standard variation, correlation analysis, regression analysis, crosstabulation analysis, cluster analysis, one-way ANOVA, and Duncan's Test. The results of analyses indicate that the subjects tended to be satisfied with thick chest and upper limbs, wide shoulder width, and preferred to be tall and have big hands and feet. By cluster analysis of 19 variables, the subjects were divided into 4 groups, each consisting 41, 138, 134, and 47 males. Because the 19 variables were body measurements transformed to eliminate the body size factor, this classification was considered to express how lean or how obese a human body appears. The results of one way ANOVA and Duncan's Test indicate that, according to the degree of leanness/obesity from Group I (lean tendency) to Group IV(obese tendency), characteristics of the body shape changed as follows; height became lower, limbs became shorter, trunk and limbs became thicker and weight became heavier. Also it showed that Group IV were most satisfied with chest girth, upper limb girth and shoulder width and Group I with height, hip girth and waist girth.

미국 음악교사자격시험의 구성요소 분석을 통한 한국 음악교원임용고사 개선방안연구

정재은 ( Jae Eun Jeong ) 한국예술교육학회 2012 예술교육연구 Vol.10 No.2

본 연구는 미국의 음악교사자격시험의 분석을 통해 내용면에서의 구성요소를 파악하고 향후 한국의 음악교원자격기준 및 자격시험 개선에 시사점을 제공하는데 주목적을 두었다. 이를 위하여 우선적으로 한국 음악교원양성체제와 음악교원임용시영을 간략하게 소개한 후, 미국의 음악교원양성체제와 음악교원자격시험을 비교·분석하였다. 미국의 50개주의 음악교원자격시험을 분류한 결과 크게 대부분의 주 (stale)에서는 국가 수중의 공통적인 음악교사자격시험을 프락시스(Praxis) Ⅱ음악교과영가를 채택하고 있었으며, 애리조나를 포함한 10개주 (애리죠나, 캘리포니아 콜로라도 조지아, 일리노이, 미시건, 뉴멕시코 뉴욕, 오리건, 텍사스 주)에서는 프락시스 Ⅱ 음악교과평가와 대등한 음악교사자격시험을 요구하였다. 이에 띠라 프락시스 Ⅱ 음악교과영가와 주에서 요구하는 대등한 음악교사자격시험의 구성요소를 비교 운석 하였으며, 이률 바탕으로 한국 음악교원임용고시의 개선 방안을 청각능력을 검증할 수 있는 내용의 포함, 연주능력을 검증할 수 있는 내용 및 평가기준의 제시, 음악교원자격시험을 치기 위한 예비교사의 자격요건 강화의 필요성을 개선방안으로 제시하였다. The main purpose of tile study is to review and analyze music teacher`s certification examination in Korea. and the U.S. Based on the result of the analysis, suggestions in Korean music teacher`s certification will be: foil wed. Finally, this study will support the development of the music teacher`s cerfication examination in Korea. For this purpose, music teacher certification systems in both Korea and the US were examined. And the comparison and analysis for music teacher`s certification examinations in the US was follewed. As a result of this analysis, among 5Ostates in the U.S, 10 states including Arizona, California, Corilado, Georgia, Illinois, Michigan, New Mexico, New Yorkm Oregon, Texas were selected the music teacher`s certification examination developed by each state. Except 10 states, all states choose the Praxis II music subject test as the tool for music teacher`s profession. As a result of this study, the component of the music teacher`s certification in the U.S were generally devided to 5 parts: listening skills, music theory, music performance, music history and culture, music education, even if the components and the ways of the selection had the slight differences. Based on the analysis and the result, three plans for aural ability were suggested for improving music teacher`s certification examination in Korea. First of all the contents for examination of the aural ability has to be included to the music teacher`s certification examination. Secondly the contents for examination of the performance ability and the criteria for the performance evaluation has to be suggested. Finally, the reinforcement of the qualification of the music teacher is needed in music teacher`s certification system.
