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.

한국산 감잎(Diospyros kaki folium)으로부터 polyphenol 화합물을 분리하여, 감잎의 기능성 식품으로서의 근거를 제시하고자, 면역기능의 활성화에 관한 실험을 행한 결과 다음과 같은 결과를 얻었다. 감잎의 폴리페놀 화합물이 면역기능에 미치는 영향에 관한 실험에서는 감잎으로부터 분리된 폴리페놀 화합물 Ⅰ, Ⅱ 및 Ⅲ에 비하여 시료를 투여한 군에서 항체생산이 증가되었으며, 특히 폴리페놀 화합물 Ⅱ와 Ⅲ에서 높은 유의성을 나타내었다. Rosette 형성의 결과에서도 감잎의 폴리페놀 화합물 Ⅱ와 Ⅲ을 투여한 군에서 분리된 비장과 복강 상재성 마크로파지에서 rosette 형성능이 높은 것으로 나타났다. Candida에 대한 시료의 탐식능을 관찰한 결과, 대조군에 비하여 fraction Ⅰ은 70%, Ⅱ는 76.8% 및 Ⅲ은 93%의 탐식능의 효과를 나타내었다. 또한, 면역기능을 담당하는 기관인 비장에 관한 세포증식능을 실험한 결과 대조군에 비하여 시료를 투여한 모든 군에서 비장세포가 증가하였으며, 시료의 농도가 증가할수록 세포증식도 증가되는 경향을 나타내었다. This study was conducted to investigate immuno functional activity of the ployphenol fractions isolated from persimmom leaves(Diospyros kaki folum). In the experiment of rosette forming cell, the results showed that all the polyphenol fractions enhanced the cell count compared with the control group. Especially polyphenol fraction Ⅱ and Ⅲ showed highly significant effect. The phagocytic activity of peritoneal macrophage on mice was significantly increased by the polyphenol fractions of the persimmon leaves compared with that of the control group. The gagocytic activity of polyphenol fraction Ⅰ, Ⅱ and Ⅲ oagainst the C. parapsilosis was 26.4%, 72% and 82.3% respectively. The pagocytic activity of the same fractions against the C. albicans was 70%, 76.8% and 93% respectively.

In this paper, the behavior of single and pile groups under lateral load are studied through laboratory experiment. Model piles were made of brass pipe with outer diameters of 28.6mm, which are laid in loose, medium, dense sand of zigzag arrangement. The test results are as follows. As the increasing of relative density, the maximum bending moment is increased. The point of maximum bending moment on single pile measured at 5∼8B(diameter of pile) depth from surface, and group piles measured at 5∼l1B. The bending moment obtained by this experiment similiar with the one obtained by the Chang's theory.

This paper presents a design method of fuzzy logic controller(FLC). In the proposed method, the parameters of FLC are determined by using Genetic Algorithms(GAs), which is an optimizing algorithm. Two types of FLC are considered. One is FLC with control rules whose fuzzy variables are all assigned by linguistic quantity. The other is FLC with control rules which are inferenced with simplified reasoning. For each FLC, the method of applying the GAs to determine the parameters of the FLC is proposed. By the simulation study for four systems with different characteristic, the usefulness of the proposed design scheme is discussed.

이 논문은 MOSFET로 구성된 등가 Half-bridge형 고주파공진형 인버어터에 대해 기술하고 있다. 시분할 방식에 의한 게이트회로를 구성하여 구동함으로써 출력단에는 두개의 인버어터에서 동작되는 순시위상이 합성되어 있어 나타나므로 부하단 출력주파수는 소자의 수위칭주파수에 대해 두배가 되고 수위칭 손실이 경감되어 소자의 평균전류가 증가한다. This paper proposes a high frequency resonant inverter consisting of equivalent half bridge model using MOSFET. In this paper time-sharing control method is applied. as a result the output frequency is two times as high as switching frequency of device and average current of device is increased because of decreasing switching loss.

This study was performed to evaluate the effect of resin and filler type on the strength of light-activated composites. Experimental composites were prepared using the four types of urethane tetramethacrylate monomers(HM-4M, TM-4M, XY-4M and DC-4M) and three different shapes of silica fillers. Cylindrical specimens of 3㎜ in diameter and 6㎜ in length and rectangular specimens of 2×2×24㎜ were prepared for the compressive test and 3-point bend test, respectively. All specimens were immersed in distilled water at 37℃ for 24 hours. Compressive and 3-point bend tests were carried out at a crosshead speed of 0.5 ㎜/min and fracture surfaces were observed with scanning electron microscope. The results obtained were summarized as follows : 1. When the size distribution of fillers was same, composites containing the spherical fillers showed the relatively higher loading rate of fillers and compressive strength than those containing the crushed fillers. 2. Compressive strength values of the composites based on UTMA monomers containing the aliphatic UTMA monomers (HM-4M and TM-4M) showed the relatively higher strength values than those of the composites based on UTMA monomers containing the aromatic or cyclohexane ring in their chemical structure(XY-4M and DC-4M). 3. The compressive and transverse strength values of UTMA-based composites were higher than those of Bis-GMA-based composites. 4. According to the microscopic observation of fracture surfaces, composite failure developed along the matrix resin and resin/filler interface region.

For develope the functional cosmetic material. we extracted the Korean persimmon leaves in 80% ethanol solution and isolated fraction I, II, III, to use Sephadex LH-20 column. Their polyphenol quantity was 20%, 70%, 82.8% individually and fraction II, III had polyphenol which included a many flavan-3-ol skeleton structure. We investigated various biological activity such a tyrosinase, xanthin oxidase inhibition, SOD-like acivity and DPPH. Inhibitory effect of tyrosinase was inhibited 51.7%, 74.7% at 50 ppm, 500 ppm of the fraction III and SOD-like activity increased quickly at 500ppm of the fraction II, III. DPPH effect had 80% electron donate ability at 50 ppm all of the fraction and xanthin oxidase was more inhibited 80% at 50 ppm of fraction II, III. These results showed possibility that polyphenols of the Korean persimmon leaves become the functional cosmetic ingredient

Data compression is needed for efficient transmission of the image data which have many redundanbies. Run-length coding is generally used for image data compression But in view of data processing by computers, run-length coding is not so desirable. We have studied about the Cascade-Division coding that is suitable for data compression with general purpose computer ormicrocomputer and then developed a software program of CD-encoding on a microprocessor 8080.
