목적 : 전자간증 산모에서 초임신부와 다산부 각각의 임상적 특징을 조사하여 비교 분석하고자 하였다. 연구방법 : 1998년 1월부터 1999년 12월까지 2년간 순천향대학 서울병원에서 입원 분만한 임신성 고혈압성 질환 환자중 초임신부 106명과 다산부 50명, 총 150명을 대상으로 임상통계학적으로 조사 분석하였다. 결과 : 분만까지 임신기간의 비교시 초임신부에서는 33-36주에서 17.9%였고 다산부에서는 34.0%로, 다산부에서 조기분만의 예가 의의있게 많았다. 신생아 체중이 2500g 미만인 군이 초임신부군에서는 36.8%였고 다산부군에서는 62.0%로 다산부군에서 더 많았다. 임신성 고혈압성 질환의 중등도를 보면 중증자간전증의 초임신부에서 35.8%와 다산부에서는 44.0%로, 초임신부에 비해 다산부군의 중증 자간전증의 비율이 많았다. 결론 : 중증 임신성 고혈압성 질환이 다산부군에서 더 많았으며 적은 주수에서 제왕절개술을 시행해 출생아의 체중이 초임신부군에 비해 더 작았고 Apgar 점수도 더 낮았다. Objective : To study the clinical differences of primiparous and multiparous preeclamptic patients. Methods : We statistically analyzed 106 primiparous and 50 multiparous preeclamptic patients who were admitted to the Soonchunhyang University Hospital from January 1998 to December 1999. Results : It was statistically found that multiparae were more likely to give premature birth than primiparae: Thirty four percents of multiparae gave birth in the period between the 33rd and the 36th gestational weeks while 17.9% of primiparae did in the same period. Sixty two percents of the newborn babies of multiparae weighed less than 2500g. Among primiparae, the ratio was 36.8%. In addition, more multiparae(44.0% vs. 35.8%) suffered from severe preeclampsia. Conclusion : severe preeclampsia was found more frequently among multiparae. Since they gave birth earlier by cesarian section than primiparae, their babies weighed less and had lower apgar scores.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

자가면역성 간염은 대개 만성 경과를 가지며, 혈중 자가면역항체와 혈청 글로불린치의 상승, 그리고 조직학적으로 괴사 염증성 변화를 특징으로 하는 질환으로 아직 정확한 병인이 밝혀져 있지 않은 상태이다. 발병연령은 대개 젊은 영자(15-25세)에서 호발한다. 이 질환은 급성 간염의 임상경과를 보일 수 있으나, 심한 급성 간염이나 전격성 간염으로도 나타날 수 있는데, 이 경우 아주 나쁜 예후를 보인다고 한다. 치료는 자가면역성 간염 임상 경과의 다양성이나 병인, 병리기전의 불확실성에도 불구하고 대개 steroid 치료에 반응하는 것으로 알려져 있으며 대개 80%의 관해율을 나타내며 궁극적으로 간경변으로의 진행을 막을 수 있는 것으로 보인다. 저자들은 58세 남자에서 발생한 급성의 경과를 가지고 심한 황달을 동반한 자가면역성 간염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hepatitis (AIH) is a chronic necroinflammatory liver disorder of unknown cause associated with circulating autoantibodies and a high serum globulin level. The age of onset of AIH show a peak between the age of 15 and 25 years. AIH can develop and be manifested as acute hepatitis, but severe form of acute hepatitis or fulminant hepatic failure has a poor prognosis. Although AIH is likely to progress from chronic active hepatitis to cirrhosis, steroid therapy can control the disease activity, prolong survival, improve the quality of life , and defer liver transplantation. In the present report we describe a 58-year-old man who admitted because of progressive jaundice and fatigue. He was diagnosed with AIH from laboratory test result showing positivity for antinuclear antibodies, anti-smooth muscle antibodies, and negativity for hepatitis viral markers and from liver biopsy. Steroid therapy, oral administration of prednisolone, was effective in improving the liver function test. Following liver biopsy 6 months after onset shows markedly improved necroinflammatory activity.

(6) 49.1% of workers were living separately from their families and 76.9% of them were self-cooking. 2) Working conditions and working history; (1) 78.1% of workers were receiving from 20,000 won 40,000won as their monthly salaries and those who were receiving from 40,000 won to 60,000 won were the next (12.5%). (2) 34.4% of workers had been working in the present plant for from one to three years and those who had been working for less than one year were 31.9%. (3) Most of workers (91.2%) were working 8 hours a day but 25.3% of precision optical instruments manufacturing workers were working about 10 hours a day. (4) Only 6.2% of workers ever changed their working places during the past one year. 89.0% of them changed once and 9.0%, twice. Male workers changed their working places more often (8.7%) than female workers (5.7%). 3) Present and past history of illness; (1) 6.7% of workers had the sick among their family members and cardiovascular diseases were most common (47.8%) (2) Those who had experiences of sickness lasted more than one week were 7.1% and those who had had operations were 3.3%. (3) 42.0% of workers were complainning at least one physical symptom. Those who were complainning "tingling pain on eye ball" were the most (20.5%), and headache, and dizziness were both the next (16.3%). 4) Smoking, drinking habits and drug dependency; (1) Among all workers, 11.7% (male, 69.5%; female, 0.4%) were smoking and 13.1%(male, 71.9%; female, 2.3%) were drinking alchole.

자연색 재현을 위한 색역 사상과 디더링

이채수,장주석 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(C)

Recently many devices print electronic images in a variety of ways. The reproduced color, however, is different from the original color because of the difference of hardware characteristics. To maintain device independent color, gamut mapping method is proposed. The proposed color gamut mapping uses nonlinear intensity mapping and clipping for saturation mapping on HSI color space. In the dithering operation, expanded nonlinear ordered dithering and modified error diffusion are proposed. The proposed ordered dithering uses expanded nonlinear quantization which considers overlapping phenomena of neighbored printing dots. In the modified error diffusion, quantization error to be diffused are adjusted to improve both image blur and color change produced in the error diffusion. So, the printed image is similar to the image of monitor. Our results indicate that proposed algorithm can produce high quality image in the low bit color devices.

In this paper, we are considered various possible disturbance conditions in order to design controller, H∞ optimal controller is successfully designed to control in such as situations. To do this, we are determined weighting function and design parameter γ to method of trial and error by Glover-Doyle algorithm. To compare with H∞-PSS and conventional-PSS which is applied in nominal system and load variations, the dynamic characteristics of H∞-PSS controller was verified which has a good response.

신경회로망 전 보상 PID 제어기에 의한 부하주파수제어

이오걸,김상효,정동일,주석민 동의공업대학 1999 論文集 Vol.25 No.1

In this paper, we propose a neural network precompensated PID(NNP PID) controller for load frequency control of 2-area power system. While proportional integral derivative(PID) controllers are used in power system, they have many problems because of high nonlinearities of the power system. Simulation results show that the proposed control technique is superior to a conventional PID controller and an optimal controller in dynamic responses about load disturbances. The proposed technique can be easily implemented by adding a neural network precompensator to an existing PID controller.
