Fast Eating Speed Increases the Risk of Endoscopic Erosive Gastritis in Korean Adults
Min-Kyung Kim,Byung Joon Ko,E-Yeon Kim,Byoung-Duck Han,조경환 대한가정의학회 2015 Korean Journal of Family Medicine Vol.36 No.6
Background: Fast eating or overeating can induce gastrointestinal diseases such as gastritis. However, the association between gastritis and speed of eating is unclear. The aim of this study was to determine whether eating speed is associated with increased risk of endoscopic erosive gastritis (EEG). Methods: We carried out a cross-sectional study involving 10,893 adults who underwent a general health checkup between 2007 and 2009. Two groups, EEG patients and EEG-free patients, were compared by using the t-test and the chi-square test. Multiple logistic regression analyses were performed to investigate the association between eating speed and EEG. Results: The group with EEG had a higher proportion of males, average age, body mass index, and percentages of current smokers and risky drinkers than those without EEG. After adjusting for anthropometric, social, and endoscopic parameters, the group with the highest eating speed (<5 min/meal) had 1.7 times higher risk for EEG than the group with the lowest eating speed (≥15 min/meal) (odds ratio, 1.71; 95% confidence interval, 1.20–2.45). Conclusion: High eating speed is an independent risk factor for EEG. Our results indicate the need for further studies to clarify the role of eating speed in gastritis.

N/A Clinical studies were carried out on 14,389 cases who had taken gastrofiberscopic examination, biopsy and X-ray from May, 1969 to May, 1984 in Han-Yang University Hospital. The results obtained were as follows; 1) Of total 14,389 cases, 7,916 were male and 6,473 were female. 55.1%, of the cases were in the 3rd and 4th decade. 2) Of total 14, 389 cases, 13, 615 showed abnormal endoscopic findings. In abnormal cases, male to female ratio was l.2: l.3) The incidence of single organ involved was 84.8% and multiple organs involved was In single organ involved cases, the most common site of disease was stomach and in multiple organ involved cases, the prevalent sites of lesions were stomach and duodenum. 4) The most frequent disease of stomach was gastritis followed by gastric ulcer. In the cases of duodenum, the most common disease was duodenal ulcer and the next was duodenitis. 5) The most prevalent disease was the chronic gastritis, and the frequency of the other upper gastrointestinal diseases was acute gastritis, gastric ulcer, stomach cancer and duodenal ulcer in orders. 6) The most frequent type of chronic gastritis was superficial gastritis. 7) Among the total cases which had been taken blood-typing, the incidence of most upper gastrointestinal diseases was not related to each blood type. But blood group 0 was common in peptic ulcer disease and blood group A in stomach cancer. 8) The clinical symptoms and signs were of no significant aid for the differential diagnosis of the various upper gastrointestinal diseases.

Background: Use of antispasmodic medication prior to colonoscopy is controversial but someone believes antispasmodic may improve visualization of colonic mucosa and ease colonoscope insertion. So, we designed a study to assess the effect of premedication with the antispasmodic, hyoscine-N-butyl bromide(Buscopan') on the performance of colonoscopy. Methods: This study was prospective, double blinded, randomized, controlled study, One hundred three consecutive patients were randomized to receive intravenous buscopan lml(n=52) or placebo(n=51) combined with our standard initial medication(me- peridine 50 mg and midazolam 2 mg). Insertion of colonoscopy was timed, and 100 mm visual analogue scales (VAS) were used for asscssing difficulty of procedure, colonic motility, frequency of positional change, frequency of external compression, difficulty of assistance and degree of discomfort experienced by the patients. Results: There were no significant differences of intubation time between buscopan group(mean time, 7.23 min., range 2~15) and placebo group(7.07 min., range 3-25), (p=0.83) and withdrawal time between buscopan group (6.46 min., range 2-22) and placebo group(6.76 min., range 2 25), (p=0.69). Also, there was no significant differences in intubation time between males and females(buscopan; males 7.00 min., females 7.60 min., p=0.34, placebo; males 7.0~5 min., females 7.08 min., p 0.44). The VAS scores checked by endoscopist(p=0.29), assistant(p=0.32) and patient (p=0.15) were not significantly different in both groups. There were no significant differences in intubation time, VAS scores nf endoscopist, assistant, and patients. Conclusion: Premedication with intravenous bu.opan has no advantage on colonoscopy procedure. Use of antispasmodic medication prior to colonoscopy was not considered as recommendable agent.

The subject of this study apply to KyungSangNamDo Sachun-Si Sachun-bay sea area for builds up a industrial complex, and inquire into the phenomenon in compared after with before reclamation. I investigated, how to remove these harmful influence and make a estimate that a water-level, flow direction and river-bed evolution by inflow of river, wave' s attack. So we have come to the conclusion as follow. 1. Water Level : After reclamation, the water-level is ascended, but the water-level is stable after dredging and changing water-course. 2. Velocity of Flow : After reclamation, back water broke out, the velocity of flow was faster after dredging and changing water-course, but the velocity of flow came to be stable in the downstream. 3. River-bed Evolution : After reclamation, the severe erosion occurred in the front of revetment, but after dredging and changing the water-course as the new stable water-course constituted, river bed evolution decreased and the flood wave flow smoothly. 4. After reclamation, the water-level remarkably increased, but the velocity of flow was nearly the same.

복합재료 이론에 의한 2차원 상판 구조물의 정확하고 간단한 해석
김준민,한봉구 서울산업대학교 2005 논문집 Vol.54 No.2
대부분의 건설기술자들은 강판형교나 콘크리트 교량을 단위 폭을 가진 보로 해석 하나 이러한 구조물은 엄연히 복합재료로 이루어진 판(plate) 구조이다. 이러한 구조물은 균등단면에 등분포하중을 받고 4변 단순 지지된 경우가 아니면 정확한 해석이 불가능하다. 복합 재료의 이론은 일반 기술자들이 이해하기 힘드나, 본 논문에서는 이러한 문제를 비교적 쉽게 정확히 해석하는 방법을 제시하고, 예로서 3경간 연속 판 교량과 포스트텐션된 강교의 해석을 보여준다.
