Adult Onset Still`s Disease에서 파종성 혈관내 응고와 다발성 장기부전이 동반된
장영광 ( Young Kwang Jang ),박현용 ( Hyun Lyoung Park ),김성후 ( Sung Hu Kim ),박성우 ( Sung Woo Park ),홍관표 ( Kwan Pyo Hong ) 대한류마티스학회 1998 대한류마티스학회지 Vol.5 No.2
Adult onset Still`s disease(AOSD) is a rare disorder of unknown etiology characterized by high spiking fever, polyarthritis/polyarthralgia, evanescent erythematous maculopapular rash, leukocytosis and the involvement of various organs. Test for IgM rheumatoid factor and antinuclear antibody are characteristically negative. AOSD is occasionally complicated by life-threatening disseminated intravascular coagulation(DIC). Factors that might be important in the development of this complication include severe disease activity, liver abnormalities and particular drugs including salicylates, non steroidal anti-inflammatory drugs and slow acting antirheumatic drugs. An AOSD with DIC, often associated with a significant hepatopathy and/or pancytopenia, should be treated early with corticosteroids and heparin to prevent a possible lethal outcome. Recently we have experienced a case of fulminant AOSD who developed a DIC, multiple organ failures and death. We report this case of fulminant AOSD with a review of literature.

논 비점오염 저감을 위한 최적관리기법(BMP) 보급 효과 분석

본 연구에서는 최적관리기법(BMP)을 실제 영농지역에 보급하여, 광역단위 논에서 발생하는 비점오염물질의 저감효과를 분석하고자 하였다. 현재까지 선행 연구들을 통해 다양한 BMP 효과 검증이 이루어졌으나, 실제 영농지역 농민들에게 BMP를 보급하여 그 효과를 측정한 연구는 부족한 실정이다. 이에 본 연구에서는 광역단위 논 지역을 대상으로 물관리기술(물꼬)과 시비관리기술(완효성 비료)을 보급하고 강우시와 비강우 모니터링을 통해 BMP 효과를 측정하였다. 연구 대상지구는 전라북도 부안군 백산면 용계리 일대로 새만금 지역에 위치하여 있다. BMP 보급 효과를 분석하기 위하여 먼저 참여농민과 농지를 선정하였으며, 관개지역과 배수면적을 구분하여 모니터링 조사 지점을 선정하였다. 연구대상지구는 SO#1(완효성 비료 95%, 비참여 농가 5%), SO#2(완효성 비료2%, 물꼬 8%, 완효성비료 + 물꼬 40%), SO#M(완효성 비료 96%, 비 참여 농가 4%) 총 3개의 배출구로 구분하였다. 각 지구별 오염부하량을 측정한 결과, 대조구 대비 SO#1에서는 수질항목별로 10.6 ∼ 85.5%, SO#2는 8.1 ∼ 45.9%, SO#M은 10.7 ∼ 86.2%의 범위로 저감된 것으로 분석되었다. 특히, SS의 단위면적당 오염부하 저감율이 가장 큰 것으로 나타났으며, TOC의 단위 면적당 오염부하 저감율은 가장 작은 것으로 나타났다. 하지만 본 연구 결과는 7월부터 10월까지 측정한 데이터를 활용하여 산정한 결과로 써레질, 이앙기간에 발생한 단위면적당 오염부하량은 포함되지 않은 결과이다, 따라서 추가적인 연구를 통해 효과를 검증할 필요가 있을 것으로 판단된다.

이병익,--,노동연,장영광 龍仁大學校 體育科學硏究所 2002 體育科學硏究論叢 Vol.12 No.1
The purpose of this study is to find out the influence to organization-absorption caused by duty stresses of employees in sports centers. To achieve this purpose, I analyzed the difference of job stresses under social and demographic characteristics, first and then the difference of organization-absorption under the same condition and finally the relationship between job stresses and organization absorption. I used a random cluster sampling to collect data from 250 respondents who worked for 12 sports centers, and actually used data were from 214 respondents excluding 36 persons who were considered to respond insincerely or omit some parts. I consisted of totally 55 questions --- six related to social and demographic characteristics, 25 related to job stress-causing factors, and the others related to organization-absorption from the measuring tools used as research tools. The statistic analysis methods used in the study are frequency, t-test, one-way analysis of variance (Oneway-ANOVA) and Scheffe's multiple range test. I finally got the following results in this study through the data analysis from the above-stated methods and procedure. First, among the job characteristics, role related factor, human relation, rewarding, and organization characteristics showed a statistically significant difference at the level of 5 percent in gender, in position, and monthly payment, in age, in service period, and position and in monthly payment, respectively. Second, among the organization absorption, defined absorption, long-service absorption, and regulatory absorption also showed the significant difference at the level of five percent in age and educational background, in age, service period, educational background, position and monthly payment and in gender, age, service period, educational background, position and monthly payment.

Background/Aims: To improve the response rate of alpha-interferon (IFN) in chronic hepatitis C, patients should be selected properly. Therefore, we assessed the usefulness of histopathological severity index in predicting the response to IFN treatment. Methods: We studied retrospectively 63 patients who had chronic hepatitis C and were treated with IFN (three million units, three times weekly, subcutaneously for 9 months). Histopathological severity index was evaluated in pretreated liver biopsies according to the modified Knodell's method. Thirty patients who sustained normal serum level of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and showed HCV-RNA loss for at least 6 months after discontinuation of treatment were classified as responders. Results: The histopathological severity indices of portal infiltration (p$lt;0.005), piecemeal necrosis (p$lt;0.005) and fibrosis (p$lt;0.005) were significantly lower in responders than in non-responders, but lobular activity showed no difference. The total score of histopatholgical severity index was significantly lower in responders than in non-responders (p$lt;0.005). The proportion of the patients showing histopathological changes of portal infiltration (p$lt;0.005), piecemeal necrosis (p$lt;0.005) and fibrosis (p$lt;0.005) was significantly higher in responders than in non-responders. Conclusions: Histopathological severity index of portal infiltration, piecemeal necrosis and fibrosis may provide an useful information in selecting patients with chronic hepatitis C for IFN therapy.
