Purpose: We investigated the expressions of Heat shock protein 27 (HSP27) and Cellular FLICE-like inhibitory protein (c-FLIP) with urothelial carcinoma of the upper tract. Materials and Methods: The expressions of HSP27 and c-FLIP were quantified immunohistochemically form sixty one patients who underwent nephroureterectomy for urothelial carcinoma of the upper tract and 10 patient’s normal ureteral tissues who underwent nephrectomy. The overall percentage of cancer cells showing staining (0% to 100%) was indicated by visual scoring. Specimens were graded from 0 to +3 intensity representing the range of staining area, for which below 1% is 0 grade, 1-10% is+1 grade, 10-50% is +2 grade, over 50% is +3 grade. Results: HSP27 positive reaction was seen in 10 of 10 cases (100%) with a normal ureter, 59 of 61 cases (96.7%) with urothelial carcinoma of the upper tract. The mean HSP27 reaction scores were 2.67 with low grade, 2.27 with high grade (p=0.045). HSP27 expression was not statistically significant according to stage and lymph node metastasis. c-FLIP positive reaction was seen in 0 of 10 cases (0%) with normal ureter, 57 of 61 cases (93.4%) with urothelial carcinoma of the upper tract. c-FLIP expression was not statistically significant according to grade, stage and lymph node metastasis. Conclusions: This study suggests that the expression of HSP27 is reduced and the expression of c-FLIP is increased in patients with urothelial carcinoma of the upper tract. If these data are confirmed, HSP27 and c-FLIP may be usable as prognostic marker of urothelial carcinoma of the upper tract.

무선 그리드 컴퓨팅 환경에서 종간간 QoS 는 매우 복잡하고 QoS 자체의 관리에 대한 증가하는 요구를 부각시켰다. 먼저 우리는 미들웨어 개체와 네트워크 개체를 포함하는 쿼럼기반의 자원 관리안을 제안한다. 두 개체들을 이용함으로써 우리는 QoS 응용의 요구사항을 만족 시킬 수 있다. 이 논문은 QoS 응용을 만족시키는 최적화 자원 쿼럼을 찾기 위한 휴리스틱한 알고리즘을 제안한다. 둘째, QoS 쿼럼에 제약된 작업 할당과 실행을 발생시키는 데이터를 최적으로 전송하는 방법을 제안한다. 실험과 건강관리를 위한 심전도 응용에 근거한 Linear Program 두 가지를 평가한다. 실험 결과는 우리의 방안이 심전도 응용의 실행시간을 단축 시켜준다는 것을 보여준다. 또한 선형 프로그래밍에 의한 결과는 사용자의 요구를 만족 시키는 노드 수를 결정할 수 있다는 것을 보여준다.
BICC 적용을 통한 WCDMA 교환망 중계 효율성 제고방안 연구
조정제(Jeong-Je Cho),김낙포(Nak-Po Kim) 대한전자공학회 2007 대한전자공학회 학술대회 Vol.2007 No.7
BICC protocol is a relay protocol adaptable to ATM and IP based core networks compared to ISUP protocol to TDM networks. Using BICC protocol, multi-rate bearer traffic such as voice and video can flow in the relay core networks. BICC protocol is standardized as WCDMA circuit switching networks in 3GPP Release 4. Thus KTF is now operating core networks using BICC protocol. In this paper, we describe the background and characteristics of BICC protocol. We also provide the status of KTF WCDMA core networks using BICC. To show the efficiency of BICC protocol an analytical simulation is given in which the results can be expected by intuitive observation.

N/A Background: The ECG QRS voltage is determined mostly by ventricular mass and also by ventricular cavity size, distance from the chest wall to the electrical center of the heart, and electrical characteristics of the tissue between the skin and the heart. Low QRS voltage is observed in patients with significant pericardial effusion. However, the relationship between the QRS voltage and pericardial fluid amount has rarely been studied. The present study was performed to evaluate the possibility that pericardial fluid amount can be predicted by using the summed QRS voltage and to determine the factors influencing QRS voltage change after pericardial drainage. Methods: Twenty-nine patients with nontraumatic pericardial effusion of moderate amount or more were included in the study. Pericardial fluid amount was determined by measuring the actively drained pericardial effusion. The QRS voltage was measured from the peak of R wave to the nadir of q or s wave, whichever was deeper. Left ventricular volume, total ventricular volume, left ventricular mass, and distance from the chest wall to the center of the left ventricle (LV) were calculated from 2-D echo guided M-mode echocardiography of the ventricle. Results: Pericardial fluid amount was estimated by total QRS voltage of 12-lead ECG recorded before pericardiocentesis with the regression equation of Y=-50X+5950(r=-0.55, p<0.05). The change of QRS voltage after pericardial drainage was related with the left ventricular mass change (r=0.65, p<0.01) but not with the amount of drained pericardial fluid and the changes of the left ventricular volume and distance from the chest wall to the center of the LV. Conclusions: The surface ECG total QRS voltage can be used to estimate pericardial fluid amount. The most important determinant of the QRS voltage change after pericardia1 drainage is LV mass change, however, other factors remain to be determined.
