추철민,이길홍 서울産業大學校 2005 논문집 Vol.54 No.3

시대의 흐름과 함께 업무에 필요한 다양한 요구사항이 발생하고 있으며 업무환경 또한 빠르게 변화하고 있다. 기존 업무 외에 새로운 업무가 추가되기도 하고 기존의 업무는 다른 업무로 대치되거나 없어지는 경우도 있다. 업무의 빠른 변화와 함께 기업에서는 빠른 변화에 대처하기 위하여 기존 시스템을 유지보수하거나 재사용을 통해 새로운 프로세스를 기존 시스템에 적용하고자 많은 자원과 시간을 투자하고 있으며 관련된 많은 연구가 진행 중에 있다. 본 논문에서는 기존의 구매발주시스템과 업무환경의 변화로 새롭게 추가도니 프로세서를 연계하여 효율적인 구매발주 시스템의 개선과 업무의 효율성을 향상하도록 하였다. 이러한 결과로 기존 구매발주시스템에서 해결하지 못한 반복오더 문제, 구매발주 후 확인처리 문제, 업체별 자료공유 문제를 개선하여 P2P기반 자동처리 모듈 설계 및 구현을 통해 처리 가능 하도록 하였다.

정반 평면도 평가를 위한 측정점의 합리적인 개수의 결정

The flatness is the most important nature for the surface table. For finding such a flatness, the surface is surveyed along a number of straight lines parallel to the edges of table, which form a grid. Next, the variations in height of the grid points are measured relative to a datum point. If the number of such points is increased. It is not necessarily to use many grid points for finding the original flatness ofa measured surface tabel. So it is necessary to find the rational quantity of such grid points. It is found that about 220 points per 1 m? of surface tabel for measurement is the rational quantity with less than about 15% error of the original flatness.

성재철,최항묵 인제대학교 2001 仁濟論叢 Vol.16 No.1

인터넷 및 통신 기술의 발달에 따라 웹을 기반으로 하는 원격 교육, 가상 대학, 원격 회의 시스템과 같은 웹 기반 응용에 대한 연구가 활발히 진행되고 있다. 특히 원격 회의 시스템이나 채팅과 같은 응용은 다른 응용에 비해 실시간성이 더욱 요구된다. 본 연구에서는 실시간성이 요구되는 웹 기반 응용에서 성능 평가를 위하여 사용된 성능 인자들과 성능 분석 기법들을 고찰함으로써 의료 영상 회의 시스템의 성능 분석을 위해 타당한 성능 인자를 결정하고 성능 분석 방안을 제시한다. As the techniques of the internet and communication are developed, the study about its web-based applications such as web-based remote education, cyber university and remote conference system are lively progressing. In particular, remote conference system and chating system require more real-time property than other applications. In this paper, I would like to investigate about "performance factors" and "performance analysis techniques" used in performance analysis for systems in web-based real-time applications and I determined the proper performance factors for performance analysis of MICS and proposed the performance-analysis method.

To compare 5-fluorouracil plus epirubicin (FE) to 5-fluorouracil plus cisplatin (FP) chemotherapy as adjuvant therapy for patients with resected gastric cancer. Between August 1995 and March 2000, 46 patients with completely resected gastric cancer received six courses of FE (5-fluorouracil 1000mg/m2/day, D2-D5, epirubicin 70mg/m2, D1) or FP (5-fluorouracil 1000mg/m2/day, D2-D5, cisplatin 70mg/m2, D1) chemotherapy. The 23 patients were assigned to each treatment group. A total of 127 courses of treatment were given both FE and FP group. The FP group tended to show more risk of overall death rate. But there were no differences between FE and FP groups in terms of overall survival or disease-free survival. Both treatment arms were generally well tolerated to chemotherapy. We concluded to be no significant differences between FE and FP groups in terms of overall survival or disease-free survival. To define the efficacy of adjuvant chemotherapy for gastric adenocarcinoma, further prospective randomized trials with large number of patients should be warranted.

航空機胴體에서 窓門切開로 因한 應力集中現象과 그 解消策의 有限要素法에 依한 硏究

金恒旭,이성철 한국항공대학교 1982 論文集 Vol.20 No.-

The stress concentration phenomena of aircraft fuselage, due to the window cut-out, is investigated by finite element method. In order to satisfy the boundary conditions and inter-element compatibility conditions up to the stress level, a new finite element is developed by compensating the handicap that the conventional membrane finite element revelas in applying it for this research problem. Equivalent nodal load assumption is done by the well known method that equated the virtual work due to the nodal load and the other due to the actual distributed load. The boundary conditions are not only those vanishing ones, but also some conditions given by the linear relations of the type:??, and the applying technique for this kind of boundary condition is worked out. fuselage is idealized to a cylindrical shell and loading is considered to be the only torsion which is the semi-monccoue aircraft skin has to take care of. The stress concentration factor is numerically calculated and the result is plotted to show the influence of the cut-out.

일산화탄소폭로시 농도와 치사시간의 관계에 관한 실험적 연구

김영오,송재철,박항배 大韓産業醫學會 1991 대한직업환경의학회지 Vol.3 No.1

The carbon monoxide(CO) is a chemical asphyxiant which serves as a major cause of death in Korea. Authors evaluated the Haber's(CχT=K :C : concentration, T : time to death) & Sidorenko's(CaχT=K; a,k : constants) equations for establishing the concentration-time to death relationship in exposure. Eighty four rats(Sprague-Dawley) were exposed to 14 different concentrations in the range of 1,600-11,100 ppm. The Sidorenko's constants 'a' was 1.79(p<0.05, r²=0.87) and 'k' was e19.41(p<0.05) for the time to respiratory arrest ; 1.61(p<0.05, r²=0.85) and e18.14(p<0.05) respectively for the time to cardiac arrest. But the results of the analysis for various concentration ranges proved that the constants were applicable only to the range from 4,100 to 11,100 ppm(a=1.76, r²=0.67, p<0.05; k=e19.13, p<0.05 for respiratory arrest and a=1.64, r²=0.62, p<0.05; k=e18.28, p<0.05 for cardiac arrest). Also, the Haber's equation was considered inappropriate for this relationship, for which the 95% confidence interval for constant a's didn't include one.

렙토스피라증의 진단에 있어 수동혈구응집반응법과 육안응집반응법의 정확도에 관한 연구

최보율,김영규,이수진,송재철,박항배 한양대학교 의과대학 1994 한양의대 학술지 Vol.14 No.2

Before 1984, Leptospirosis had been reported sporadically in middle inland of Korea as hemorrhagic pneumonia like disease, epidemic pulmonary hemorrhagic fever or epidemic pneumonitis since 1975. The epidemiologic characteristics of this disease were found out and the agent was isolated microbiologically after a large epidemic in 1984. Thereafter many consecutive studies for leptospirosis had been performed in the realm of epidemiology, microbiology and clinical field. But in order to appropriate control of Leptospirosis there are many problems such as organizing surveillance system for early diagnosis and treatment, identifying sero-group and serovar in each epidemic area and assessing vaccine efficacy. The objectives of this study was to find out easily applicable diagnostic methods to be used in a rural community surveillance system. Two diagnostic methods, passive hemagglutination(PHA) test and macroscopic agglutination test(maAT) were measured against their accuracies, sensitivity, specificity and predictive value of positive and negative. 301 sample sera from 270 human cases was collected through Leptospirossis surveillance system in a rural community during 1989-1992. Microscopic agglutination test(MAT) were used for confirmed diagnosis according to WHO guideline with 4 strains; Icterohemorrhagiae lai and Canicola canicola Hond Utrecht IV as standard strians and 6P-014-1 and YP-35-1 as strains isolated in Korea in 1986. The results are as follows. 1. 75(24.9%) among 301 sample sera and 49(18.1%) among 270 persons was serologically positive with MAT. 2. Agreement between PHA and MaAT was very low(k-coefficient≤0.252). 3. In PHA, specificity was very high(≥0.96) but sensitivity was very low(≤0.28). 4. In MaAT, specificity(≥0.73) was relatively lower than PHA but sensitivity (≥0.79) was significantly higher than PHA, especially false-positive rate case was absent in MAT's high antibody titer(above 1:640). It was concluded that MaAT method was a very useful diagnostic tool for early diagnosis of Leptospirosis in a rural community surveillance system, provided that confirmed diagnosis with MAT method be carried out in laboratory of medical school or research institute such as National Institute of Health or Provicial government Institute of Health and Environment.
