Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

Objective This study aimed to introduce a method to remove huge ovarian tumors (≥15 cm) intact with single-port laparoscopic surgery (SPLS) using SW Kim`s technique and to compare the surgical outcomes with those of laparotomy. Methods Medical records were retrospectively reviewed for patients who underwent either SPLS (n=21) with SW Kim`s technique using a specially designed 30×30-cm2-sized 3XL LapBag or laparotomy (n=22) for a huge ovarian tumor from December 2008 to May 2016. Perioperative surgical outcomes were compared. Results In 19/21 (90.5%) patients, SPLS was successfully performed without any tumor spillage or conversion to multi-port laparoscopy or laparotomy. There was no significant difference in patient characteristics, including tumor diameter and total operation time, between both groups. The postoperative hospital stay was significantly shorter for the SPLS group than for the laparotomy group (median, 2 [1 to 5] vs. 4 [3 to 17] days; P<0.001). The number of postoperative general diet build-up days was also significantly shorter for the SPLS group (median, 1 [1 to 4] vs. 3 [2 to 16] days; P<0.001). Immediate post-operative pain score was lower in the SPLS group (median, 2.0 [0 to 8] vs. 4.0 [0 to 8]; P=0.045). Patient-controlled anesthesia was used less in the SPLS group (61.9% vs. 100%). Conclusion SPLS was successful in removing most large ovarian tumors without rupture and showed quicker recovery and less immediate post-operative pain in comparison to laparotomy. SPLS using SW Kim`s technique could be a feasible solution to removing huge ovarian tumors.

최근 각종 제어시스템에 분산제어 시스템을 이용하는 경우가 늘고 있는데, 각 플랫폼에 따른 호환성 결여로 인하여 여러 가지 문제가 야기되고 있다. 본 논문에서는 이러한 어려움을 극복하기 위하여 사용 환경에 관계없이 각 분산제어 시스템을 연결하고자 개방구조를 설계하였다. 이를 위하여 OSI 7 layer model을 따른 protocal을 개발하였으며, 이것을 RPC와 XDR을 이용하여 구현하였다. 전체 시스템은 속도와 호환성을 모두 고려하였지만, 속도와 호환성이 모두 문제가 되는 것은 호환성을 위주로 설계하였다. Recently, many kind of control system is implemented by DCS(Distributed Control System). But that situation the compatible problem between different flatform system is arised. In this paper, we are about to describe the design of the system that makes a user to satisfy scalability, portablility, interoperability which is the characteristic of the open structure in DCS using real time control theory and microprocessor applicable technique. For this, we developed a protocal that followed OSI 7 layer model, and implemented this protocol using RPC and XDR. The system is considered the speed and the compatibility, but in the case of some problems in compatibility and speed, out design is intented to choose compatibility.

목적: Demonstrate a new instrument, technique or procedure 방법: In this video, we showed how to remove huge ovarian tumors in sinlgel port laparoscopic surgery by SW KIM`s method. SW KIM`s method is the technique to put a huge ovarian tumor into a specially designed extremely large endopouch (XXXL: 30x30㎠sized) using two conventional laparoscopic needle holders and one laparoscopic grasper and gravity by changing the patient`s position. After identifying the infundibulopelvic and uteroovarian ligaments salpingooophorectomy including huge ovarian tumor was performed by LigaSure. And then ovarian tumor was located in the pelvic cavity by changing the patient`s position into reverse-trendelenberg position and a XXXL endopouch was inserted and un-rolled inside the abdominal cavity. To insert a huge tumor into the XXXL endopouch, the endopouch was opened in triangular shape. Bilateral apex of baseline of trianglular opening of the endopouch was hold by two needle holders and then the upper apex was hold by a grasper. After holding three point of endopouch opeing, the patient`s position was changed into deep trendelenberg postion, then the tumor came into the endopouch by gravity. While changing the patient`s position, 2 needle holders and a graspers were moved into the pelvic cavity from the abdominal cavity. Aftere identifying the tumor inside the endopouch, tumors could be removed through the single port opening site or transvaginally in laparoscopic hysterectomy case without spillage of ovarian tumor. 결과: The advantage of SW KIM`s method is to remove ovarian tumor without spillage in a single port laparoscopic surgery by putting it into the large endoscopic bag despite narrow space. 결론: Using a specially designed 30×30 cm sized XXXL Endopouch and SW Kim`s technique, huge ovarian tumors could be removed without spillage in single port laparoscopic surgery.

연구배경: 비혈연간 조혈모세포이식은 HLA체계에 대한 이해의 증진과 새로운 검사법의 개발, 그리고 기증자 수의 증가에 힘입어 최근 빠르게 증가하고 있다. 방법: 가톨릭조혈모세포이식센터에서 1995년 10월부터 2001년 12월까지 비혈연간 이식을 받은 138명의 성인 환자를 대상으로 후향적 분석을 하였다. 결과: 질환별로 만성골수성백혈병 66예, 급성림프구성백혈병 23예, 급성골수성백혈병 16예, 재생불량성빈혈 21예, 골수이형성증후군 9예, 비호지킨림프종 2예, 그리고 발작성야간혈색소뇨증이 1예였다. 일차 생차부전은 분석가능한 136예 중 4예(2.9%)에서 발생하였다. Ⅱ도 이상의 급성이식편대숙주병의 발생률은 48.1%였고, 만성이식편대숙주병은 49.5%였다. 재발 이외의 사망원인 중 가장 높은 빈도를 보인 것은 폐렴으로, 독성사망 64예 중 36예(52.3%)에서 관찰 되었다. 만성골수성백혈병의 경우(n=66), 무병생존율, 재발률, 비재발성 사망률이 각각 45.7%, 11.4%, 49.2%였다. 무병생존율은 표준위험군이 고위험군에 비해 통계적으로 유의하게 높았다(50.3% vs 32.0%, p=0.03). 급성림프구성백혈병의 경우(n=23), 무병생존율, 재발률, 비재발성 사망률이 각각 30.0%와 49.4%, 44.8%였던 반면, 급성골수성백혈병에서는(n=16) 28.6%, 39.4%, 52.9%였다. 이들 급성백혈병에서는 표준위험군에 비해 고위험군에서 재발률과 비재발성 사망이 모두 높게 관찰되었다. 중증재생불량성빈혈의 경우(n=21), 무병생존율과 비재발성 사망이 37.3%와 62.7%였다. 결론: 본 연구의 결과 비혈연간 이식은 HLA적합 형제가 없는 혈액질환 환자들에게 유용한 치료법의 하나임을 알 수 있었다. 낮은 병기에서의 조기 이식과 분자생물학적 방법을 사용한 HLA 적합도의 개선이 이식관련 사망을 최소화시켜 비혈연간 이식의 효과를 더욱 확대시킬 수 있을 것으로 생각된다. Background: Unrelated allogeneic stem cell transplantation (U-SCT) is recently on a increasing trend supported by better understanding of HLA system, development of new HLA typing, and increase of donor pool. Methods: We retrospectively analyzed 138 adult patients who underwent U-SCT between October 1995 and December 2001 at Catholic Hematopoietic Stem Cell Transplantation Center. Results: Diagnoses were chronic myeloid leukemia (CML, n=66), acute lymphoblastic leukemia (ALL, n=23), acute myeloid leukemia (AML, n=16), severe aplastic anemia (SAA, n=21), myelodysplastic syndrome (MDS, n=9), non-Hodgkin lymphoma (NHL, n=2), and paroxysmal nocturnal hemoglobinuria (PNH, n=1). Primary engraftment failure was observed in 4 (2.9%) of 136 evaluable patients. Acute GVHD (≥grade II) occurred in 48.1% and chronic GVHD occurred in 49.5%. The most common cause of death other than relapse was pneumonia, which occurred 36 (52.3%) of 64 toxic deaths. In CML, disease-free survival (DFS), relapse rate, and non-relapse mortality (NRM) was 45.7%, 11.4%, and 49.2%. DFS of the standard-risk group (SR) was significantly better than that of high- risk group (HR) (50.3% vs 32.0%, P=0.03). In ALL, DFS, relapse rate, and NRM was 30.0%, 49.4%, and 44.8%, whereas corresponding figures for AML were 28.6%, 39.4%, and 52.9%. NRM and relapse rate were higher in HR compared to SR in acute leukemia. In SAA, DFS and NRM was 37.3% and 62.7%. Conclusion: We concluded that U-SCT is a feasible therapeutic option for patients lacking a HLA-matched sibling donor. Transplantation at earlier phase of disease with more accurate HLA matching by molecular typing can minimize treatment-related toxicity and could extend the benefit of U-SCT.

This study was carried out to investigate subjective respiratory symptoms and their attributable factors in Korean dental laboratory technicians. A questionnaire was mailed to randomly selected 1,900 dental laboratory technicians. Among them, 1,344 dental technicians completed the questionnaires and returmned them. Validity and reliability tests on the questionnaires were carried out before the main survey. To investigate risk factors on respiratory subjective symptoms, we performed analysis on distribution of characteristics, and then investigated univariate analysis and multiple logistic regression analysis. The prevalence rate of wheezing, cough and phlegm, and dyspnea was 4.8%, 33.9%, 54.9%, respectively. Statistically significant factors inducing subjective respiratory symptoms by multiple logistic regression analysis were sex, smoking, exercise, health examination, work hours a day, investment gas, investment dust, metal fume, resin vapor, and asbestos dust. Considering the results above, it seems that most subjective respiratory symptoms are related with health habits and occupational environmental-related factors. The result, consideration in mind, suggest that health promotion programs for smoking cessation, regular health examination, and physical exercise in health habit, and improvement on casting and resin work in dental technological environment be necessary.

ATM 망에서 ABR 트래픽을 제어하기 위한 EFCI 스위치와 ER 스위치의 혼합

김내진,김진태,박기태 건국대학교 1996 대학원 학술논문집 Vol.43 No.-

새로운 ATM 서비스인 ABR은 최근에 발생된 서비스 클래스이다. ATM 망에서 속도기반 흐름제어 방식은 목적지 또는 망 스위칭 노드에서 발생하는 RM셀들에 포함된 궤한정보를 기반으로하여 ABR트래픽 소스들의 전송속도를 제어하는 것이다. 결국 사용자에게 유용한 대역폭을 할당하는 것이다. ATM 망이 다른 속도제어 방식 즉, EFCI 모드와 ER방식을 사용하는 스위치로 구성되었을 때, 망성능과 대역폭 할당의 공정성에 관하여 연구하였다 ABR, new ATM service, is service class that currently was originated. The rate-based flow control mechanism in Asynchronous Transfer Mode(ATM) networks controls the transmission rate of Available Bit Rate(ABR) traffic sources, based on feedback information contained in the Resource Management(RM) cells coming from the destination and the network switching nodes. Finally by controlling traffic flow, available bandwidth to users is allocated. This paper investigates network performance and fairness of bandwidth allocarion When an ATM network consists of switches using different rate control mechanims, namely, the Explicit Forward Congestion Indication(EFCI) mode and the Explicit Rate(ER) mechanism
