Upper gastrointerstinal bleeding is a common problem in clinic. Causes of bleeding are peptic ulcer, esophageal varices, erosive gastritis, Mallory-Weiss tear in Korea. On the management of gastrointestinal bleeding, the patient must be hemodynamically stabilized. In the past 5 years, new endoscopic treatment have been developed that offer promise for the cessation of active bleeding and prevention of recurrent bleeding. The results of scolorotheraphy become better than operation in any cases of liver cirrhosis. On management of esophageal varices, there are emergency sclerotherapy and prophylactic therapy. There are several methods, electrocoagulation, laser photocoagulation, injection therapy in management of nonvariceal patients.

안성훈 啓明大學校 醫科大學 1990 계명의대학술지 Vol.9 No.2

Since 1980 year, colonoscopy has been used commonly for the detection of colorectal diseases in Korea . In the past, colorectal diseases were less common in Korea than western countries because of fiber rich diet and other environmental factors probably. But according to recent reports, colonic diseases has been increased in Korea. This report analyzes 531 patients undergoing colonoscopy during 1982-1989 year at Keimyung University Hospital. 1. Males were more common than females(54.2% to 45.8%). 2. The colorectal diseases were most frequent in fifth decade as 22%,20.3% in fourth decade, 18.6% in third decade and then sixth in order of frequency. 3. On colonoscopic findings, patients of colorectal carcinoma were most common as 20.2%, 10.5% of tuberculosis, 9.5% of polyp and 3.4% of ulcerative colitis. 4. The colorectal cancer was frequently involved in fifth decade, fourth decade and then in sixth decade. 5. Ascending colon was most common location of colorectal cancer, next in rectosigmoid colon, descending colon, transverse colon in order. 6. Polyps were found most frequently in rectorsigmid colon as 44%, transverse colon as 24%, ascending colon as 16%, entire colon as 2%, Polypectomy were performed in 74% of partients. 7. There was no serious complication during or after procedure. Colonoscopic prodedure is a safe, accurate and simple method for detection of colorectal diseases.

m−SHEL 모델에 의한 건설 중대 사고재해의 휴먼에러 배후 요인 분석

안성훈 한국건축시공학회 2022 한국건축시공학회지 Vol.22 No.4

As human factors are the most important cause of construction accidents, it is important to reducehuman error in construction work to reduce accidents. However, the error forcing context inorganizational situations acts as a factor behind human error. Therefore, fatal construction accidentswere analyzed using the m-SHEL model, which can identify the factors behind human errors. Throughsuch analysis, it was found that there are differences in the detailed factors behind human errorsaccording to the type of fatal accidents in construction, This study is meaningful in that it confirmedthrough accident cases that it is important to understand and respond to organizational situations inorder to reduce human error in construction work. 건설 사고재해의 가장 큰 원인은 인적요인이므로, 건설공사에서 휴먼에러를 감소시켜 사고재해를 감소시키는 것이 중요하다. 그러나, 휴먼에러는 조직적 상황의 연속적인 흐름이 배후 요인으로 작용한다. 따라서, 휴먼에러의 배후 요인을 파악할수 있는 m-SHEL 모델을 사용하여 건설 중대 사고재해를 분석하였다. 분석 결과, 건설 중대 사고재해 유형에 따라 휴먼에러를 일으키는 배후 세부 요인이 차이가 있다는 것을 파악하였으며, 휴먼에러 배후 요인 중 L-m 요인, L-H 요인, L 요인 순으로많이 차지하고 있는 것을 알 수 있었다. 본연구는 건설공사에서 휴먼에러를 줄이기 위해서는 조직적 상황을 파악하고 대응하는 것이 중요하다는 것을 사례를 통해서 확인하였다는 점에 의의가 있다.

Background: A hyperosmolar nonketotic state has been known to have a high mortality, and even now, despite this high mortality, only a few studies of this disease have been performed. We studied the prognostic factors for the hyperosmolar nonketotic state. Methods: We retrospectively studied the cases of 40 patients who were in a hypersomolar nonketotic state when admitted to Sanggye Paik Hospital during the 6-year Period from 1995 through 2000. We divided the hyperosmolar nonketotic patients into two groups, the complete recovery group and the incomplete recovery group, and compared the clinical features, the laboratory findings, and the precipitating factors between two groups. Results: 1) A total of 40 patients were studied: 24 in the complete recovery group and 16 patients in the incomplete recovery group. The mortality rate was 32.5%. 2) No significant statistical difference existed among the clinical features of the two groups, except for the sex(p<0.01). 3) Among the laboratory findings of both groups, analysis revealed that the effective osmolarity was significantly higher among those in the incomplete recovery group(p<0.01). Serum sodium concentration was also significantly higher among those in the incomplete recovery group(p<0.01). Serum creatinine was also significantly higher among those in the incomplete recovery group(p<0.05). Serum bicarbonate concentration, on the other hand, was significantly lower among those in that group(p<0.05).4) Infection was identified as the most common precipitating factor(62.5%). Among the precipitating factors of the two groups, there were significant statistical difference in pneumonia, UTI, and inappropriate glucose control. 5) A significant statistical difference existed among the initial level of consciousness of both groups(p<0.05). 6) The only significant independent factor responsible for prognosis of nonketotic hyperosmolar state patients was the sex. Conclusion: The sex was only significant independent prognostic factor of nonketotic hyperosmolar state patients.

Cost budgeting is a fundamental component of cost management, establishing a baseline for building construction projects. However, previous studies suggest that the cost budgeting at most construction companies are not systematically conducted. The purpose of the present study is to reveal the key factors which influence cost budgeting and to weight these key factors related to building construction projects. A questionnaire survey for identifying the factors which influence cost budgeting was conducted with cost budgeting experts. The analytic hierarchy process was employed to weight the relative importance of the factors identified. The results showed that data is most important category and level of design documents is most important factor. However, gaps of importance between factors are small, so it is revealed that all of 35 factors are influencing the cost budgeting. Research for using these weights of key factors influencing the cost budgeting is needed to quantify the level of cost risk during cost budgeting process, which enables cost planners and management to use improving the reliability of cost budgeting for building construction projects.

An Evaluation of Green Manufacturing Technologies Based on Research Databases

안성훈 한국정밀공학회 2014 International Journal of Precision Engineering and Vol.1 No.1

The International Journal of Precision Engineering and Manufacturing-Green Technology (IJPEM-GT) was inaugurated in order to foster knowledge sharing and collaboration of researchers in the field of “green manufacturing.” While emerging technologies can be evaluated by business points of view such as Hype Cycle of Gartner, in this paper, journals and research areas in green manufacturing were evaluated by using research databases such as Web of Science and Journal Citation Report. Using impact factor and the number of published papers as key parameters, journals in subjects of Engineering-Mechanical, Engineering-Manufacturing, Engineering-Environmental, and Energy and Fuels were compared. From the point of researchers, the H-Index and the number of published papers were evaluated for journals and technologies in green manufacturing. The H-Index of journals or research areas was proportional to logarithm of the number of papers, and linear trend lines were observed from the data. The journals in green technology show higher gradient in the trend line compared with the journals in manufacturing and environmental areas. In addition, a Four Stage Model (early-emerging-developed-saturated stages) of technology development was proposed.
