임창인,이은주 大田工業大學 1992 한밭대학교 논문집 Vol.9 No.1

본 논문에서는 규격화된 형식문서에서 필기 한글 숫자 부호를 인식하는 알고리즘을 제안 하였다. 형식문서에 쓰여진 한글과 숫자는 특징 정보에 의한 구조 해석적 방법으로, 기호는 사영 투사와 매칭 방법으로 인식이 이루어진다. 본 알고리즘을 팩시밀리 메시지 패턴 인식에 적용한 결과 99%의 인식률과 한장의 메시지 패턴 인식에 2분 이하의 처리 시간이 소요되어, 그 유용성을 확인할 수 있었다.

N/A Twenty-three patient with chronic constipation under- went studies of total and segmental colonic transit of radio-opaque markers to determine the utility of this test in chronic constipation for further diagnostic and therapeutic plans. The subjects ingested 1 radio-opaque marker at 9:00 AM on each of 3 consecutive days while they were fully ambulatory, A plain abdomen was obtained on the 4th day. Repeated plain abdomen was obtained on the 7th day if the markers did not pass on the 4th day. The abdomen was divided into 3/areas of interest using bony landmarks: the right colon, the left colon and the rectosigmoid area. The markers are counted in each site on X-rays taken on the 4th day; these markers were multiplied by 1.2 The result were as follows: 1) Colonic transit studies showed 3 different groups: colonic inertia (n=9), outlet obstruction (n=6), and normal transit (n=8), 2) The mean trasit time in the total colon was 28.47± (24.27hr) (mean±SD) in chronic constipation and 10.57+12.80hr in the normal controls (p<0.01). 3) The mean transit time in the right colon was 8.04±9.72 hr in chronic constipation and 3.87±7.23 hr in the normal controls (p<0.01). Corresponding values in the left colon were 10.64±13.23hr and 3.31±5.01 hr (p<0.01) and, in the rectosigmiod, 9.91±14.54 hr and 3.27±5.56hr, respectively (p<0.01). 4) Colonic transit was delayed in chronic constipation about 3 times more than in the normal controls (p<0.01). 5) Colonic transit was delayed predominantly in the left colon. In summary a colonic transit study using radiopaque markers is a simple and useful test in the evaluation of chronic canstipation.

Percutaneous endoscopic gastrostomy (PEG) was introduced into clinical practice in 1980 and has become a preferred method of feeding gastrostomy tube placement. Since our first description 1986 in Korea, PEG has supplanted its surgical counterpart in many Korean institutions. During the periods from January 1986 to December 1990, we have managed 102 patients with a PEG. This study reviewed our experience with PEG with respect to the incidence of PEG-related problems and the efficacy of the procedure. 1) Mean age of patients were 43 years(range 15∼78), Primary diagnosis in 102 patients undergoing PEG was head trauma; 63, stoke; 20, CO poisoning; 4, brain tumor; 2, esophageal cancer; 5, cardiac cancer; 6, esophageal poerforation; 1, esophagobronchial fistula; 1. 2) PEG was succesful in 95 patients (93%) and mean operation time was 15 minutes (range 9∼42). Seven patients failed to have a gastrostomy placed for technical reasons including; previous gastrectomy; 2, no transillumination; 2, broken silk suture during procedure; 2, large ventral hernia; 1. 3) The PEG tubes remained well in 88 patients with functioning over 3 months and the longest functioning of PEG tube was 27 months to date. 4) Weight gain was noted in 66 of 88 patients (75%) and mean weight gain was 38%. 5) The incidence of PEG-related complications was 18% and three postoperative death occurred which were related to the patients underlying disease. This author's experience with these 102 patients has led to the conclusion that PEG is safe, easy to perform, and effective means of establishing access for enteral feeding.Key Words: Percutaneous endoscopic gastrostomy, enteral feeding.

A Study on Efficient Management Strategy for Soil Erosion

Soil value was estimated 26 trillion Korean won and recent climate change due to global warming is highly affecting soil erosion. Especially, about 10% of surface soil was annually eroded because of massive construction in Korea. Main purpose of this research was i) to investigate occurrence, mechanism, affecting parameters of soil erosion especially focused on wind erosion and ii) to conduct wind tunnel experiment for evaluating feasibility of dry fog system in stabilizing wind erosion. Result of wind tunnel experiment showed that wind erosion could be reduced about 22-38% after applying dry fog system. Two parameters, soil particle size and spreaded water drop size, are main parameters to affect efficiency of wind erosion stabilization and smaller water drop size is more effective to prevent wind erosion than soil particle size. In terms of wind erosion management, evaluation of soil erosion should be conducted for environmental impact assessment (EIA) when land usage is changed or massive construction was conducted. Since there is no evaluation form of soil erosion in EIA, not only soil erosion but also wind erosion evaluation should be included in the EIA. In addition, transaction of soil and rock open portal recycle system (TOCYCLE) could be utilized to recycle surface soil and consequently, prevent wind erosion and conserve value of soil. Overall, dry fog system is an effective technique for wind erosion preventing system and it could be combined with natural and/or artificial soil conservation system to enhance wind erosion prevention. Furthermore, policy and management system for preventing soil erosion should be thoroughly reviewed to make better soil conservation.

In the past, hepatic infarcts were rarely diagnosed before autopsy, and mast of them were fatal, but recently hepatic infarction were earier diagnsised due to developed equitments such as ultrasonogram, CT scan and angiogram. We experienced a case of hepatic infarction associated with shock and review of hpatic infarction. A-21-year-old male was admitted to the hospital because of abdominal pain and vomiting for 3 days previously. Massive hepatic infartion developed with clinically characterized epigastric and right upper quadrant pain, fever, jaundice, ileus; and biochemically by moderate leukocytosis and markedly elevated transaminase, alkaline phosphatase, total bilirubin levels, prologation of prothrombin time and activating partial prothombin time. The diagnosis was made in vivo by abdominal computed tomography (CT), sulfer colloid liver spleen scan. Angiography revealed irregular ill defined lesion and hypovascularity on inferior segment of the right lobe but intact main hepatic artery. Needle aspiration of the liver might be confirm the diagnosis. His symptoms and laboratory finding were significantly improved 1-2 weeks after treatment with intravenous fluid, vitamine-K, fresh frozen plasma, platelet transfusion, albumin, broad spectrume antibiotics. He is well being with favorable state for 3 months since discharge and follow up 5 months abdominal CT for previus hepatic infaction was almost normalized.
