Background: Acute respiratory distress syndrome (ARDS) remains a life-threatening disease. Many patients with ARDS do not recover fully, and progress to terminal lung fibrosis. Angiotensin-converting enzyme (ACE) inhibitor is known to modulate the neurohormonal system to reduce inflammation and to prevent tissue fibrosis. However, the role of ACE inhibitor in the lungs is not well understood. We therefore conducted this study to elucidate the effect of renin-angiotensin system (RAS) blockage on the prognosis of patients with ARDS. Methods: We analyzed medical records of patients who were admitted to the medical intensive care unit (ICU) at a tertiary care hospital from January 2005 to December 2010. ARDS was determined using the Berlin definition. The primary outcome was the mortality rate of ICU. Survival analysis was performed after adjustment using propensity score matching. Results: A total of 182 patients were included in the study. Thirty-seven patients (20.3%) took ACE inhibitor or angiotensin receptor blocker (ARB) during ICU admission, and 145 (79.7%) did not; both groups showed similar severity scores. In the ICU, mortality was 45.9% in the RAS inhibitor group and 58.6% in the non-RAS inhibitor group (P = 0.166). The RAS inhibitor group required a longer duration of mechanical ventilation (29.5 vs. 19.5, P = 0.013) and longer ICU stay (32.1 vs. 20.2 days, P < 0.001). In survival analysis, the RAS inhibitor group showed better survival rates than the non-RAS group (P < 0.001). Conclusions: ACE inhibitor or ARB may have beneficial effect on ARDS patients.
The Reliability and Validity of a Foregn Language Listening
김주해 한국영어학회 2005 영어학 Vol.5 No.2
This study evaluates the reliability and validity of the Foreign Language Listening Anxiety Scale (FLLAS, Kim, 2000), designed by the researcher specifically to measure listening anxiety of foreign language learners. The analyses of internal consistency (r = .90) and test-retest reliability (r = .85) in the study reveals that the FLLAS is a reliable measure by nature and across time. In the validation study, evidence of construct validity is found in the correlations seen between the FLLAS scores and other variables related to comprehension or general anxiety. The correlation between the FLLAS and the Marlowe-Crown Social Desirability Scale is examined as a final step to detect undesirable response tendencies. The non-significant correlation between the two scales implies that listening anxiety items are not overly influenced by perceptions of social desirability. Overall, the FLLAS is proven to measure what it is supposed to measure reliably and validly.

전자봉인 장치는 능동형 RFID 장치로서, 화물 컨테이너의 문에 설치되어 컨테이너가 허가받지 않은 자에 의해 개봉되지 않았다는 것을 보증해 주는 장치이다. 전자 봉인장치는 RFID를 이용하므로 도청이나 위조를 막아야만 한다. 또한 보안 프로토콜을 사용하는 전자봉인 장치는 복제가 불가능해야 한다. 전자봉인의 복제 방지 기능이 제공되지 않는다면, 공격자는 컨테이너의 내용물을 바꾸어 넣은 다음에 복제된 전자봉인으로 재봉인 함으로서 전자봉인이 개봉 되었었다는 사실을 숨길 수 있을 것이다. 본 논문에서는 도청과 위조를 방지함과 동시에, 봉인의 복제에 대한 저항성을 갖는 프로토콜을 제안하고자 한다. An eSeal(Electrical Seal) is an active RFID device which installed on the door of a container. The main role of the tag is to make sure the seal is not breaking by unauthorized people. Because an eSeal uses RFID system, we need to prevent eavesdrop and impersonate. Moreover, an eSeal which uses a secure protocol must not be able to duplicate. If duplication resistant property is not provide to a eSeal, an attacker may replace a object in the sealed container and reseal the container with duplicated eSeal to hide breaking of the eSeal. In this paper, we provide a protocol which resist duplicate an eSeal during prevent eavesdrop and impersonation.

Authars reviewed and analyzed the 96 cases of the unstable proximal humerus fracture surgically managed in the department of orthopaedic surgery of Catholic University Medical College from 1987 to 1993. Analysis dealt with the fracture classification, the clinical assessment, surgical method and related complication, operative result. The overall results were as follows: 1. According to the classification by Neer (1970), 46 cases were 2 part fracture, 16 cases 3 part fracture, 24 cases 4 part fracture, 8 cases fracture -dislocation and 2 cases head splitting fracture; Of 8 cases of fracture -dislocation, 2 cases(3part-1 / 4part-1) were the iatrogenic dispiaced cases during manual reduction of 2 part fracture -dislocation. 2. The surgical methods were as follows; for fracture fixation of 80 cases, buttress T-plate in 48 cases, Rush pin and wire in 9 cases, cancellous screw and wire in 8 cases, Steinmann pin and wire 8 cases, Seidle nail in 3 cases, Herbert screw and wire in 1 case and Steinmann pin in 1 case were used respectively. Herbert screw was used in 6 cases for major or supplementary fixation. And joint replacement in 16 cases( 14 hemiarthroplasty / 2 total arthroplasty ) were performed. 3. The Operative results were analyzed with postoperative radiograph: 1) Of 80 cases of open reduction; adequate reduction in 51 cases, inadequate reduction in 21cases( varus-9, valgus-4, malreduction of greater tuberosity-4, highly lacated implant-3, excessive shortening-1), insufficient fixation in 5 cases, joint penetration of screw in 2 cases, iatrogenic shaft fracture in 1 case. 2) Of 16 cases joint replacement; adequate replacement in 12 cases, improper fixation or management of greater tuberosity in 3 cases, inappmpriate retrotorsion of humeral component in 1 case. 4. Functional assessment by Neer's method was done as follows: Of 80 cases open reduction group, excellent and satisfactory results in 59 cases, unsatisfactory and failure results in 21 cases. Of 16 cases joint replacement group, satisfactory results in 10 cases and unsatisfactory results in 6 cases. 5. Complications occurred as follows: 1) Of SO cases of open reduction; malunion with joint stiffness 26 cases, impingement in 4 cases, fixation loss in 3 cases, axillary nerve palsy, distant pin migration and avascular necmsis of humeral head in each 1 case. 2) Of 16 cases of joint replacement; joint stiffness in 7 cases, loosening of humeral component in 4 cases, nonunion of greater tuberosity and axillary nerve in each 1 case.

32 cases of intraarticular and periarticular fractures treated with the Herbert bone screw were analyzed retrospectively by radiographic and functional assessment in the department of orthopaedic surgery of Catholic University Medical College from 1989 to 1994. 1. According to the anatomical distribution, there were various fracture sites as follows: 11 cases of carpal scaphoid, 7 cases of distal humerus, 4 cases of proximal radius, 3 cases of proximal humerus, 3 cases of femoral head, 2 cases of distal radius, metacarpal head and medial malleolus in each 1 case. 2. Early and late radiographic assessment showed some complications as follows: 1) Through eariy radiographic assessment, there were 2 cases of inaccurate reduction of fracture fragment, 2 cases of inappropriate fixation (out of bone) and 1 cases of insecure fixation followed by displacement of fracture fragment. 2) Through late radiographic assessment, there were 3 cases of posttraumatic arthritis, 2 cases of avascular necrosis of the osteochondral fracture fragment; Of 3 cases of posttraumatic arthritis, 2 cases were related to the pmgressive protrusion of screw head resulting from degenerative thinning of the articular cartilage. Through this study, it was stressed that 1. Fracture personality must be evaluated for the appropriate use of Herbert screw, consideang the fracture pattern and sites. 2. The head including a trailing thread must be inserted into the subchondral bone to prevent the protrusion of screw head, being aware of the progressive thinning of cartilage resulting from the inevitable posttraumatic arthritis or avascular necmsis of fracture fragment. 3. In the cases of osteochondral fracture deserving the shear force by musculotendinous pulling and joint motion, Herbert screw seems to be undesirable. 4. The Herbert screw is effective method, but needs skill and experience if errors are to be avoided.

54 unipolar pmstheses and 61 bipolar prostheses with same femoral stem were examined clinically and radiologically at an average of 34 months postoperatively. The average age of the patients in unipolar group was 74 years and 71 years in bipolar group. All prostheses had been inserted due to femoral neck fractures. There were two cases of dislocations, two cases of acetabular erosion in unipolar group and bipolar group, respectively. Dislocated prosthetic head was reduced with closed method in unipolar group, meanwhile open reduction was required in bipolar group. One case of early failure was found in cemented bipolar arthroplasty at post-op 2 years follow-up. Functionally, the results were excellent and good in 70.4% of unipolar group and in 73.8% of bipolar group. There was no significant difference between unipolar and bipolar arthoplasty.
