      • Poster Session : PS 0831 ; Upper GI Tract : Clinical Factors to Predict Angiographically Detectable Non-Variceal Upper Gastrointestinal Bleeding in Patients Refractory to Endoscopic Treatment

        ( Tae Hwan Ha ),( Tae Hoon Oh ),( Sung In Yu ),( Min Kim ),( Jong Wook Kim ),( Won Ki Bae ),( Jae Hyung Kim ),( Seung Suk Baek ),( Mi Jin Ryu ),( Ye Na Choi ),( Ji Young Park ),( Eileen L Yoon ),( Tae 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

        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.

        장애인과 저축 : 저축 결정 요인과 고용상태 및 생활만족도 효과

        윤상용,김태완 한국장애인고용공단 고용개발원 2012 장애와 고용 Vol.22 No.3

        본 연구는 장애인과 자산축적행위로써 저축과의 상호적 관계를 실증적으로 규명하고자 한 연구가 부재한 상황에서 패널 데이터를 분석자료로 하여 종단분석을 통해 장애인 가 구의 저축액 변화 결정 요인과 저축액 변화가 장애인의 사회참여와 삶의 질 변화에 미치 는 영향을 규명함으로써 장애인 대상의 자산형성지원제도 도입의 근거를 마련하고자 하 는 것을 목적으로 하고 있다. 장애인고용패널 데이터의 2008년과 2010년의 변화량을 분석자료로 하여 다항로짓분 석을 실시한 결과, 장애인과 저축과의 상호적 관계는 통계적으로 유의하였다. 우선, 장애 인 가구의 저축액 변화 결정 요인으로 통계적 유의성을 가진 변수로는 제도적 요인으로 서 기초보장수급 여부, 개인적 요인으로서 가구소득과 소득분위, 보건의료비, 차량유지비, 노후대비 여부, 성별, 고용상태 및 부의 학력으로 나타났는데, 이러한 결과를 통해 가구 경제상태와 장애인의 고용상태 등에서의 긍정적인 변화가 저축액의 증가 및 유지를 가져 오는 주요한 요인임을 확인할 수 있었다. 한편, 저축액의 변화가 장애인의 고용상태 및 생활만족도에 미치는 영향을 규명하고자 한 다항로짓분석에서는 저축액이 장애인의 사회참여에 영향을 미치는 주요한 요인 중의 하나임을 확인할 수 있었다. 즉, 저축액의 긍정적인 변화가 장애인의 고용상태를 개선하 고 생활만족도를 제고하는 데 유의미한 영향력을 행사하고 있음을 보여주었다. 이러한 연구 결과에 비추어 볼 때, 장애인을 대상으로 한 자산형성 지원 제도의 도입과 관련하여 실증적인 측면에서 일정 수준 타당성을 확보했다고 할 수 있다. Recently in Korea asset building programs for people with low income have been introduced as a new policy for escape from poverty. Until now there is no study on people with disabilities and asset. The objective of this study is to identify the determinants of saving and effects of saving on social participation using data of Panel Survey of Employment for the Disabled(PSED) and suggest the asset building program for people with disabilities. The result of the multinomial logit analysis of the determinants of saving shows recipency of basic security as institutional factor and household income, deciles of household income, health and medical expense, owned car maintaining expense, provision for old age, sex, employment status and father's education level as personal factors have an statistically-meaningful impact on saving in households with the disabled people. The result of the multinomial logit analysis of the effects of saving on employment status and life satisfaction also shows that savings as the variable of asset in households with the disabled people have an statistically-meaningful impacts. In other words, these results say the more households with the disabled people have savings, the better the employment status and life satisfaction of people with disabilities. Viewed in these results of this study there is need to introduce asset building programs for people with disabilities in the near future.

        윤태성,정수영 國立 昌原大學校 産業技術硏究所 1999 産技硏論文集 Vol.13 No.-

        In this study, we proposed the frequency domain Sato and CMA (Constant Modulus Algorithm) blind equalization algorithms that have the improved convergence speed characteristics using the orthogonal transforms (DFT, DCT-Discrete Fourier/Cosine Transform). And then, the convergence characteristics of the frequency domain CMA/Sato (DFT-CMA, DCT-CMA/DFT-Sato, DCT-Sato) are compared with those of the conventional LMS based CMA/Sato blind algorithms for the real data and the complex data(4QAM, 16QAM). Simulation results show that the frequency domain Sato and CMA blind equalization algorithms have better convergence speed, especially when the distortion of the communication channel increases, than the conventional CMA.

      • 열가소성 Wood-Plastic Composites의 기계적 물성에 미치는 커플링제의 영향

        윤태호,신경섭,황택성,이존태 공주대학교 자원재활용 신소재 연구센터 1999 1차년도 센터 성과집 Vol.1999 No.-

        목분 충진제의 함량을 달리 하고 PE수지를 매티릭스로 하여 wood plastic composites(WPC)를 제조하였다. 또한 매트릭스와 충진제간의 계면결합력을 증가시키기 위하여 커플링제로 phthalic anhydride(PA)를 사용하였으며, 충진제의 충진률과 커플링제 처리가 복합재의 기계적 물성에 미치는 영향과 계면현상을 관찰하였다. 목분의 충진률 30wt%, PA커플링제농도 3wt%일 때 인장강도는 26.37MPa로 최대값을 나타내었으며, 이때 충격강도는 46.24J/m의 최대값을 나타냈다. 또한 WPC는 주사전자현미경 관찰을 통해서 커플링제의 처리농도의 증가에 따라 목분과 PE 수지와의 분산과 결합이 잘 이루어졌으을 확인할 수 있었다. Wood powder as reinforcing fillers and polyethylene as a matrix have been used for wood plastic composites(WPC). In preparing WPC, the coupling agent, phthalic anhy dride(PA) was used in order to increase the interfacial bonding force between matrix and fillers. In this study, the effect of wood powder, PA concentration on the mechanical properties and interfcial phenomena on the composites was eveluated. The tensile strength of 3wt% PA-treated composites reached its maximum value of 25.91 MPa when the wood powder content was 30wt%, and the mximum impact strength of PA-treated composites was 46.24H/m. SEM observation showed that wood powder was well dispersed and bonded well with PE matrix by increasing the coupling agent concentration.

        정수처리공정상 염소소독부산물형성에 미치는 오존의 영향

        성낙창,박현석,이성식,이용희,이종팔,윤태경 한국환경과학회 2004 한국환경과학회지 Vol.13 No.1

        The effect of ozone on the formation and the removal of disinfection byproducts(DBPs) of chlorination process was studied to elucidate the performance of water treatment process. The samples of raw water, prechlorination process, and preozonation process were analyzed quantitatively according to the Standard Methods for the Examination of drinking water. As a result, most of total trihalomethanes(THMs) which were formed in prechlorine treatment process was not removed in the preozonation process. Most of haloacetic acids(HAAs), haloacetonitriles(HANs), and chloral hydrate(CH) was removed in sedimentation and biological activated carbon(BAC) filtration processes. However, DBPs were increased more or less by postchlorine step. In particular, the formation of THMs and HAAs depends on ozone more than chlorine, but, the formation of HANs and CH depends on chlorine more than ozone. The seasonal variation of DBPs concentration for the year needs to be investigated to study the temperature effect because DBPs strongly depend on temperature among various efficient factors.
