We report a case of spontaneous cervical epidural hematoma caused by a pure epidural arteriovenous malformation. A 22-year-old woman developed a sudden quadriplegia after a vigourous physical therapy including multiple acupunctures for her neck pain. Emergency cervical magnetic resonance image showed an epidural hematoma in her cervicothoracic junction. Emergent decompressive laminectomy and an evacuation of the hematoma were performed. A soft tissue mass found in the hematoma was proven to be an arteriovenous malformation. Postoperatively, the patient experienced some complications. However, she recovered completely from the motor weakness.

The purpose of this study is to explore the practice patterns and effects of PE teachers who voluntarily operate the ‘clustered school sports club league' reflected in the policy through a bottom-up approach. In order to investigate various factors influencing teachers' practice, the framework of 'teacher agency' was used. In-depth interviews were conducted with three physical education teachers and two students participating in the league, and data were collected through participation and non - participation observation and local document records. The collected data were analyzed using the framework of description, analysis and interpretation presented by Wolcott (1994). The characteristics of the league's operation were 1) a league which students take precedence 2) a teacher focusing on more important things. The general growth background of teacher and the experience of league operation and school council as a teacher were revealed in the iterational level. From the perspective of the projective, students' self-reliance and healthy social citizens who contributed to the communities were confirmed. And from the perspective of practical-evaluative, a sense of responsibility and self-sacrifice for students in terms of cultural, active support of fellow teachers in terms of structural, and securing facilities and budgets in terms of material were verified. This study was identified the patterns of practice, effects and factors by examining the complex and multifaceted teacher's creative and subjective activities through the frame of ‘teacher agency’. This is expected to contribute positively to the development of alternatives and the establishment of an upward policy improvement plan to promote the practice of teachers as a change entity. 본 연구는 체육교사의 주체적 실천행위가 발휘된 성공사례인 클러스터형 학교스포츠클럽 운영양상을 탐색하고, Priestley, Biesta, & Robinson(2015)의 행위주체성 개념 틀을 활용하여 실천의 요인을 분석하는데 목적이 있다. 2016년부터 현재까지 운영되고 있는 리그를 2018년 3월부터 8월까지 총 6개월 동안 리그 운영 체육교사 3명과 리그 참여 학생 2명을 대상으로 심층면담과 관찰을 실시했으며, 현지문서를 수집하였다. Wolcott(1994)의 기술, 분석, 해석의 틀을 활용하여 자료를 분석하였다. 이에 대한 결과로 첫째, 두 가지의 해당리그 운영의 특징, 둘째, 세 가지 차원의 실천행위에 미치는 요인(반복적 차원, 투영적 차원, 실천적·평가적 차원), 셋째, 세 가지의 교육적 효과가 확인되었다. 본 연구는 변화 주체로서의 교사 실천을 촉진하기 위한 대안 마련 및 상향접근식 정책 개선안 수립에 긍정적 기여를 할 것으로 기대된다.

Objective : placement of ventricular catheter is important to achieve long-term patency of the shunt system. We describe a method of calculating the insertion site, trajectory, and the length of the ventricular catheter using CT parameters in shunt surgery. Patients and Methods : These can be rapidly obtained using a caliper from a scout cut and two axial scans at lateral ventricular and upper 3rd ventricular level. To compare this technique with traditional one, we analyzed 40 consecutive patients who underwent shunt surgery. Results : Of 20 patients undergoing ventriculoperitoneal shunt insertion using this technique, none had poor location of the proximal catheter. In the counterpart, 9 patients had poor location(p=0.001). The number of patients who required revision surgery were also lower in the group using this technique, but it was not statistically significant (4 versus 2, p=0.422). Mean follow-up period was shorter in this technique group. Conclusion : This technique provides an accurate placement of the proximal catheter without special instrument or additional expenses.

27 cases of femoral neck fractures which were treated in department of orthopaedic surgery of CNUH from 1979 Jan. to 1985 Jan, were analysed clinically and radiologically. Very sensitive, noninvasive, simple and easily reproducible bone scanning with 99m Tc was introduced fro early diagnosis of avascular necrosis as a complication of femoral neck fracture. The results were as follows: 1. The most common cause of fracture was slipping and falling down. 2. In classification, transcervical and subcapital fractures were most common in anatomical classification, Pauwels' type I in Pauwels' classification and Garden stage 3 in displacement. 3. Singh index was decreased according to increase of physiological age. 4. Avascular necrosis develops commonly in Pawels' type 3, Garden's stage 4 and subcapital fracture. 5. Satisfactory results were obtained 75% in internal fixation and 85% in head replacement. 6. Bone scan is considered to be significant technique for early detection of vascular impairment to the femoral head after femur neck fracture, and is important in selecting the method of treatment according to results of bone scan.

직접 가열식 열탈착 공정을 이용한 유류오염토양의 정화

민형식,양인호,정상조,김한승,Min, Hyeong-Sik,Yang, In-Ho,Jeon, Sang-Jo,Kim, Han-S. 한국지하수토양환경학회 2009 지하수토양환경 Vol.14 No.5

본 연구에서는 lab-scale의 열탈착 장치를 설계 및 제작하고 실제 유류오염 토양을 대상으로 다양한 운전조건에 따른 오염토양정화성능을 비교하였다. 대상 토양은 군부대로 사용되던 부지 내 유류저장소 부근 고농도 오염토로 선정하였고, 10 L 용적의 원통형 batch 형태의 직접 가열식 열탈착기를 사용하여 초기 TPH 농도 4476 ppm의 고농도 오염 토양시료를 다양한 운전조건에서 열탈착하여 처리효율 분석을 수행하였다. 열중량 분석을 통해 열탈착 실험에서 대상 오염물질을 제거하기 위한 토양 시료의 평균 가열온도는 $200-300^{\circ}C$가 적합한 것으로 확인하였다. Batch 형식의 운전을 통한 처리효율 분석 결과 토양 내 오염물질을 90% 이상 제거하기 위해서는 약 $200^{\circ}C$에서는 10분, 약 $300^{\circ}C$에서는 5분 이상의 처리 시간이 요구되었다. 함수율이 높고 덩어리진 토양일수록 처리효율, 특히 고분자 오염물질의 처리효율이 크게 감소함을 보였다. 따라서 풍건을 통하여 오염토양 내 수분을 저하시킨 후 분쇄 처리하여 열탈착기에 주입하는 것이 효과적이라 판단된다. 또한 처리 전 토양과 처리 후 토양의 물리화학적 특성 비교한 결과 고온에 의해 증발된 수분함량을 제외하고 나머지 특성들은 거의 변화가 없어 실제 복원현장에서 오염토양을 열탈착 공정을 이용하여 오염물질을 제거한 후 추가적인 후처리 과정 없이 처리토양을 원래 위치에 복원하는 것이 가능함을 확인하였다. 본 연구결과는 현장운전에서 오염물질의 제거 효율을 극대화하기위한 인자 결정 및 검증을 위한 기초자료로 활용될 수 있을 것으로 사료된다. A field soil highly contaminated with petroleum hydrocarbons (JP-8 and diesel fuels) was employed for its remediation by a lab-scale thermal desorption process. The soil was collected in the vicinity of an underground storage tank in a closed military base and its contamination level was as high as 4,476 ppm as total petroleum hydrocarbon (TPH). A lab scale directly-heated low temperature thermal desorption (LTTD) system of 10-L capacity was developed and operated for the thermal treatment of TPH contaminated soils in this study. The desired operation temperature was found to be approximately $200-300^{\circ}C$ from the thermal gravimetric analysis of the contaminated field soils. The removal efficiencies higher than 90% were achieved by the LTTD treatment at $200^{\circ}C$ for 10 min as well as at $300^{\circ}C$ for 5 min. As the water content in the soils increased and therefore they were likely to be present as lumps, the removal efficiency noticeably decreased, indicating that a pre-treatment such as field drying should be required. The analysis of physical and chemical properties of soils before and after the LTTD treatment demonstrated that no significant changes occurred during the thermal treatment, supporting no needs for additional post-treatments for the soils treated by LTTD. The results presented in this study are expected to provide useful information for the field application and verification of LTTD for the highly contaminated geo-environment.

민형식,이정효,장인택,김상준 中央醫學社 1989 中央醫學 Vol.54 No.4

Aztreonam is a new, synthetic monocyclic betalactam antibiotics with excellent vitro activity against the majority of aerobic gram-negative bacilli and betalactamase stability. To evaluate its efficacy effect, clinical and laboratory studies were performed 25 cases in acute abdomen at Department of Surgery, College of Medicine, Chung Ang University, Yong San Hospital. The results were as follows. 1) The total number of patient was 25, 18 male and 7 female. 2) There were 9 cases of gastric and duodenal disease, 2 cases of small intestin disease, 9 cases of appendiceal disease, 2 cases of colon disease and 3 cases of biliary tract diseases. 3) In 25 cases that Aztreonam was administrated, 23 cases were cured (92 %) and 2 cases were partial response. 4) Among 25 patients, organism were cultured in 20 cases and 5 cases had culturenegative. 22 clinical strains were isolated in the 20 cases. E-coli was the most common organism (31.6 %) and Klebsiella in 5 strains and Enterobactor in 4 strains in respectively. 5) All isolated gram-negative organism were sensitive to Aztreonam, but gram-positive organism (Staphlycoccus) were resistant. Bacteriologic response rate was 91 %. 6) Elevation of serum aminotransferase was observed in 2 cases of patient.
