Objectives : The authors sought to examine the differences in the number of P300 detected by subjects in experimental and control groups when exposed to relevant stimuli. In addition, the authors tried to determinethe subjects' reaction time when asked to respond to relevant stimuli. Methods : The subjects were 20 informed female volunteers aged 22-38 years (median age : 24). Relevant stimuli (concealed information) were created by unknowingly exposing the two groups to obscene pictures and semantic questions. The number of P300 detected and the length of reaction time were compared between the two groups. Results : Contrary to theauthors' expectations, there were no significant differences in the number of P300 detected or in the length of reaction time between the two groups. Conclusions : These results indicate that, unlike a polygraph test, concealed information tests adopting P300 and reaction time as major physiological responses ofsubjects exposed to meaningful personal information might not serve as a valid practical tool in the field of criminal psychology. However, further studies involving a greater number of subjects are needed before a final conclusion regarding the validity of this new type of concealed information test can be drawn.

참여정부의 국방획득 제도개선 추진의 결과로 방위사업법이 제정되고, 이 법에 따라 방위사업청 산하 정부출연 법인체로 '06년 2월 2일 새로운 조직의 국방기술품질원(이하 기품원)이 탄생하게 되었다. 이에 기품원 사천센터에서 있었던 T-50엔진(F-404-102)의 내구성 시험평가 현황을 알아보고 이 과정에서 느낀 교훈을 살펴보고자 한다.

To get high effi챠ency in variable speed control of induction motor, It is required that the vector control should be separated from flux component current and torque component current.<br/> In this paper, the vector control IS modeled by the estimation of the stator flux, Representing induction motor speed controller as a digital system with the use of the 32bit DSP, improves the motor control performance, The IGBT is used as the switching device and the validity of the proposed vector control is proved through voltage, current wave and the characteristics of the velocity response as the drive circuit being simplified

We report the case of a patient with primary renal amyloidosis, who was progressed to fulminant hepatic failure. A 68-year-old man visited our hospital for evaluation of anorexia, weight loss and hepatomegaly. Laboratory examination revealed proteinuria and azotemia. He was confirmed to have primary amyloidosis by renal biopsy. His renal function progressed to deteriorate rapidly with marked deterioration of liver function with cholestasis. Peritoneal dialysis and steroid therapy were started for reduction of urine output and rapid progression of azotemia, and aggravation of liver function. Azotemia was improved after peritoneal dialysis but the liver function worsened leading to hepatic failure, causing death. If jaundice has progressed in any patients with primary amyloidosis, liver transplantation and stem cell transplantation should be considered for preparation of hepatic failure.
