Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

정진우,박진홍 한국교원대학교 과학교육연구소 1997 청람과학교육연구논총 Vol.7 No.1

본 연구는 지구과학 개념에 대하여 중학교 학생들이 지니고 있는 심리적 개념 위계 구조를 밝히고, 교과서에서 제시한 교수 순서와 학생들의 심리적 위계에 따른 교수 순서의 수업 효과를 비교함으로써 효과적인 교수 순서를 알아내는데 목적이 있다. 연구 목적을 휘해 세 개의 단운에서 학습 과제 분석을 통하여 주요개념을 추출하였다. 개념 형성 검사지롤 개발하여 서열화 이론으로 중학생들의 심리적 위계를 분석하였다. 또한 심리적 위계의 효율성을 검증하기 위하여 실험집단에는 심리적 위계에 의한 교수 순서를 제시하고 통제집단에는 교과서에서 기술된 순서로제시하였다. 본 연구의 결과는 다음과 같다. 1. 학생들의 심리적 위계 구조는 교과서의 논리적 위계 구조와 반드시 일치하지는 않는다. 2. 심리적 위계 순서로 수업한 실험집단이 통제집단에 비해 개념의 성취도에서 통계적으로 유의미한 차이를 나타냈다(p<.05). The purpose of this study is to investigate the psychological hierarchy structure of the Earth Science concepts and to determine the effective teaching order by comparing the teaching effects of the psychological hierachy order with those of teaching order of the current text. To study this purpose, key concepts were selected by the tasks analysis in three units. Concept formation tests were developed and ordering thoery was used to identify middle school students' psychological hierachy. To test effects of the psychological hierarchy, teaching with psychological hierarchy order was applied to experimental group and teaching with concept order descripted in the current text was applied to control group. The major results of this study are as following: 1. The students' psychological hierarchy structure are not always consistent with logical hierarchy structure in the current texts. 2. The mean score of experimental group applied psychological hierarchy order was significantly higher(p<.05) than the control group in the concept achievement.

정진홍,강운선 大邱大學校 師範大學 附設 敎育硏究所 2009 學校敎育硏究 Vol.5 No.1

이 연구의 목적은 대구․경북 지역의 사회과 교사와 국어과 교사는 다문화 교육에 대한 인식과 이해의 정도에서 차이가 있음을 밝히는 것이다. 이를 위하여 다문화교육에 관한 선행연구를 고찰하여 다문화 교육의 목표와 다문화 교육에 대하여 교사들이 취할 수 있는 다양한 관점 등을 정리하고, 그것에 근거하여 설문지를 구성하였다. 설문지는 우편과 온라인의 방법으로 배부하였으며, 169부의 설문지가 분석 대상으로 활용되었다. 다문화교육 이해도와 다문화교육 목표에 대한 관점의 차이를 검증하기 위해 t-test, 분산분석(ANOVA)을 활용하였다. 분석 결과는 국어 교사와 사회과 교사의 다문화교육 이해도에서는 차이가 없었으며, 다문화교육 목표에 대한 관점에서도 오히려 국어 교사가 더 배려적인 것으로 조사되었다. The objective of this study was to examine the degree of understanding and perspective on multicultural education of secondary school Korean and social studies teachers in the Daegu/Gyeongbuk region. In order to achieve the goal of this study, I set the following hypotheses: 1) Social studies teachers will have a higher degree of understanding for multicultural education than Korean teachers; 2) Social studies teachers sided more with the goal of consideration type multicultural education compared to Korean teachers. In order to verify the above-mentioned hypotheses, this study implemented verification and analysis procedure using statistics processing program (SPSS 14.0). In order to examine teachers' characteristics, the degree of understanding for multicultural education, and frequency of the perspectives on the goal of multicultural education, I utilized frequency analysis. In order to verify the reliability of the measurement method, I implemented verification by using Cronbach’s Alpha. In addition, in order to verify the difference of the degree of understanding for multicultural education and perspectives on multicultural education goal according to teachers' census statistical characteristics, I utilized t-test and ANOVA. Therefore, I came up with the following analysis results: First, most of the respondents had heard of multicultural education and understood the concept of multicultural families, however a few teachers understood "negatively" by answering that multicultural education is education for encouraging students from multicultural families, education about minority group cultures, and alternate curriculum for current curriculum, which is for students from multicultural families. Second, respondents answered that they do not agree that multicultural education is for minority groups to give up their mother tongue and culture and accept the mainstream society's culture in order to live in the mainstream society, Third, as a result of the hypotheses verification, Hypothesis 1 and 2 was rejected.

저자들은 Creutzfeldt-Jacob병 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 약 4개월에 걸친 비교적 짧은 기간 동안 중증의 인지 기능 장애와 시각 장애, 보행장애와 하지의 약화, 불수의적 운동 등과 함께 섬망상태에까지 이르게 되어 본원 정신과에 입원하게 되었다. 정신상태 검사상, 반응시간의 지체, 언어장애와 보속증, 시간에 대한 지남력 장애, 주의 집중력 장애, 단기 및 장기 기억 장애, 추상적 사고능력 장애 등의 소견을 보였고, 이러한 증상들은 입원후 치료에도 불구하고 빠르게 악화되었다. 뇌파검사상 지속적인 다발초점성 서파가 모든 전극에서, 특히 우측 전두부에서 현저하게 나타나는 소견을 보였고, 병리조직학적 검사상 대뇌 피질에 신경손실을 동반한 해면화와 신경교 증식증을 나타냈다. 이상의 소견들은 모두 CJD의 진단에 합당하였다. We report a case of Creutzfeldt-Jacob disease and review the relevant literatures. This 56-year-old male patient was admitted to our hospital with a history of rapidly progressing cognitive dysfunction, visual disturbance, gait disturbance, weakness, involuntary movement of lower extremities, and the symptoms of delirium. On mental status examination, he showed psychomotor retardation, speech disturbance, perseveration, disorientation, impairment of short-term and long-term memory, and inability of abstract thinking. He had a rapid downhill course, along with shakiness of trunk, rigidity of the limbs, myoclonus, confusion, and finally, inability to speak or move on the bedside. On electroencephalogram(EEG), continuous multifocal show delta activities were found in all leads, especially in the right frontal areas. Brain biopsy showed, spongiosis with neuronal loss and gliosis noted at the cerebral cortex. These findings were compatible with Creutzfeldt-Jacob disease.

The purpose of this study is twofold. One is to evaluate the wettability of 4 elastomeric impression materials on tooth and different kinds of filling materials. The other is to identify the effect of topical surfactants sprayed on the surface of each impression. The elastomeric impression materials used in this experimental study were one polyether(Impregum F) and three polyvinyl siloxanes(Provil novo, Zerosil, Imprint). The abutments were prepared for 3/4 crown or onlay on the extracted human first molar. The filling materials used in this study for the duplication of prepared abutment were composite resin, amalgam, and casting metal. Impression was taken by manufacturer's recommendations and the number of voids on the impression surface was counted. The topical surfactants were Spannex Ⅱ?? and Cohere??. The wettability was evaluated by comparing the number of voids between non-treated group and treated groups. The results were as follows: 1. Zerosil?? showed the least number of voids on the impression surface. The number of voids increased in order of Provil novo??, Impregum F??, and Imprint??. 2. Impregum F?? and Zerosil?? showed the least number of voids on the surface of dental stone master cast. The number is increased in order of Provil novo?? and Imprint??. 3. When abutment material is tooth, the number of voids on the surface of master cast was smallest compared with that of other abutment materials. The number of voids increased in order of casting metal, amalgam and composite resin. 4. The number of voids on the surface of the dental stone master cast was smallest when SpannexⅡ?? was used, followed by Cohere?? treated group and non-treated group. These results suggest that the difference in wettability caused by the types of rubber base impression materials as well as abutment materials can affect the number of voids. And the use of topical surfactant for rubber base impression materials can improve the wettability of the materials and enhance the accurate master cast which has fewer surface voids.

The orbital blowout fracture occurs when a convex object(usually a baseball and a fist) larger in diameter than orbital rim strikes the orbit, increasing intraorbital pressure and producing hydraulic forces in all directions, which explodes the bony margin. The most frequently site of fracture is the bony floor in the region of the infraorbital canal, less frequently medial orbital wall, that is, lamina papyracea. Medial orbital wall fractures are also seen with other types of facial fractures such as frontal, nasoethmoid, and maxillary injuries. With the advent of nasal endoscope, endoscopic intranasal reconstruction has substituted for external approach. We experienced a case of blowout fracture of left medial orbital wall, which was treated with endoscopic intranasal reconstruction method and report this case with the review of the literature.

In patients with unilateral condylar hyperplasia, increased length of the condylar neck causes deviation of the mandible to the opposite site, resulting in facial asymmetry, but the arch form and general contour of the displaced mandible is approximately symmetric. So, the unilateral condylectomy have been prefered surgical method among the surgeons. The purpose of this study is to analyze the postoperative results comparatively following two different surgical methods, condylectomy and ramus surgery, in unilateral condylar hyperplasia. Case of 6 patients with the unilateral condylar hyerplasia were analyzed in this study, 3 case of the condylectomy only, 3 cases of the ramus surgery, Clinical and radiographic evaluations were tried for comparison. In conclusion, comparative results between two groups did not show any significant difference,but we confirmed that unilateral condylectomy could be a excellent surgical methods in unilateral condylar hyperplasia thinking over the unique morphological characteristics of it.
