Meningoencephalocele is a herniation of meninges, cerebrospinal fluid and brain parenchyma from the skull. It is rare mass, usually occurring in childhood. It is classified as occipital, basal, sincipital on the basis of its anatomical location. Sincipital meninogoencephalocele with an internal cranial defect is localized between the frontal and ethmoid bones. The authors herein report on a 43-year-old woman presented with protruding mass on glabella area with naso-frontal deformity. The cranial end of the lesion was amputated by median frontal craniotomy and bony-dural defect was reconstructed by using autografts. The patient showed an uneventful recovery from anesthesia and skull base surgery.

지능형 옥외 광고 시스템을 위한 RFID 콘텐츠 미들웨어
조상연(Sang-Yeon Cho),김광렬(Kwang-Ryeol Kim),한광록(Kwang-Rok Han) 한국컴퓨터정보학회 2007 韓國컴퓨터情報學會論文誌 Vol.12 No.6
보행자의 관심을 고려하지 않고 일방적으로 광고하는 현재의 옥외 광고보드의 단점을 개선하기 위하여 본 논문에서는 보행자의 RFID 태그에 기록된 정보를 수집하고 분석한 후에 고객들의 관심을 끌 수 광고만을 디스플레이하는 지능형 광고 시스템의 개발을 목표로 한다. 이를 위하여 인식한 RFID 데이터를 필터링하고 분석하여 의미있는 이벤트를 생성하여 해당하는 광고 콘텐츠를 스트리밍하도록 RFID 콘텐츠 미들웨어를 제안한다. RFID 미들웨어는 Sun Java RFID 소프트웨어로 구현하였으며 RFID 에뮬레이터를 작성하여 실험을 수행한 결과 보행자 정보에 따라 광고를 디스플레이 하는 것을 확인하였다. This paper sets a goal at developing an intelligent advertising system that displays only an advertisement in which interests passers by collecting their RF1D information and analysing it in order to improve the defect of outdoor advertising boards which unilaterally advertise regardless of people's interest. For this purpose, we propose a RFID contents middleware which generates a meaningful event and streams an advertising content corresponding with the passers' interest after filtering and analysing the recognized RFID data. We implemented the RFID middleware with Sun Java RFID software and made an experiment by designing a RFID emulator. As a result of the experiment. we found that this system displays the advertisement according to the passers' information.

식도정맥류 환자에서 식도이단 전후의 식도운동기능 및 직달수술의 성적

N/A Esophageal pressure was compared between esophageal varix and control group and also between before and after transection of the esophagus in variceal patients. Different types of non-shunt operations were perfomried on 157 esophageal varix cases from January 1979 to June 1992. The LES (lower esophageal sphincter) pressure was hiigher in variceal patients than in control group and it was decreased after transection of the esophagus. There were no significant differences in the amplitude and duration of the esophageal contractions between the esophagal varix and control group. The same was true before and after the transection. Of the 157 patients, 116 were male and 4l were female with ratio 2.8:1 and 81.6% were between 30 and 59. Of the 157 operations 80 were Sugiura operations, 61 were Kobayashi operations, 11 were TEPG and 5 were Hassab operations. Operative. mortality rates of prophylactic, elective and emergency surgery were 4.5%, 8.5% and 35%., respectively and of Childs criteria A, B and C werc 1.7% 11.3% and 28.6%, respectively. Of the total 135 intraoperative wedge liver biopsies, 108 cases revealed cirrhosis (80.6%), 12 cases chronic inflammation, 11 cases fibrosis and in 3 cases, no pathologacal findings were found. Postoperative complications include wound infection (21 cases), pleural effusion (17 cases), rebleeding (8 cases), esophageal leakage (5 cases), esophageal stenosis (5 cases) and others. The overall rnortality within one month after the surgery was 10.8% (17 cases) and the major causes of death were hepatic failure (,9 cases) and rebleeding (5 cases). Follow up esophagograms were obtained in 103 patients and in 45 patients varices disappeared compietely and in 50 patients, there were significant improvements.
