N/A Background : To evaluate the cellular immune response to interferon(IFN)-α and ribavirin combination therapy in patients with chronic hepatitis C, we monitored serum levels of soluble IL-2 receptor(sIL2R) before and after the therapy. Methods : Serum sIL2R levels before and after the combination therapy were measured in 19 patients with chronic hepatitis C. IFN(3 MU/day, 3 times/week) and ribavirin 1000 mg/day were administered for 24 weeks to all patients. Results : After the therapy, sIL2R levels were increased (before, 3.13 0.67 ng/m L, and after 4.08 2.13 ng/mL, p=0.059) but statistically insignificant(p>0.05). The patients were divided into two groups : the responder group who were negative for serum hepatitis C virus(HCV)-RNA after the therapy, and the non-responder group who were still positive for HCV-RNA after the therapy. Between these two groups, sIL2R levels before and after the therapy were not significantly different. The ratio of sIL2R levels before and after the therapy was calculated, although the ratio was higher in responder group, but there was no significant difference between the two groups(sIL2R after the therapy)/(sIL2R before the therapy) : 1.43 0.70 in the responder group and 1.04 0.28 in the nonresponder group, p=0.096). Conclusion : Although these results failed to demonstrate that sIL2R level was increased during the combination therapy in patients with hepatitis C, this study suggested that cytokines which mediate immune response may be involved in the pathogenesis of chronic heaptitis C virus infection.(Korean J Med 59:511-515, 2000)

본 연구는 해양쓰레기 발생예측의 정화도를 높이는 수치로 활용할 목적으로 해양쓰레기 발생의 원인이 되는 변수가 무엇이 있는지를 조사하고 해당 변수의 영향도를 가중치로 계산하는 방법을 연구하고자 하였다. 해양쓰레기 발생량 예측을 위해 계절, 기상, 하천유역 인구밀집도, 산업, 해안특성 등 해양쓰레기 발생에 영향을 주는 인자가 무엇인지 시계열 분석을 통해 선별하고 각 인자별 영향도를 알아내기 위하여 임의의 예측모델을 만들고 해당 모델의 예측치와 해양환경정보포털의 해안쓰레기 모니터링 통계과 비교하였다. 연구결과 지역, 계절별로 해양쓰레기 발생예측에 적용되는 변수별로 가중치가 달라짐을 확인하였다. 본 연구는 통계자료를 기반으로 진행되었기 때문에 각 변수별 가중치의 정확도를 측정하는 데에는 한계가 있었다. 향후 현장조사 데이터를 기반으로 추가 연구가 이루어진다면 신뢰성 있는 해양쓰레기 발생예측 모델이 만들어 질 것으로 기대한다. For the purpose of using it as a value to increase the degree of purification of marine waste generation prediction, this study investigated what variables cause marine waste generation and studied how to calculate the influence of the variables as weights. In order to predict marine waste generation, factors affecting marine waste generation, such as season, weather, river basin population density, industry, and coastal characteristics, were selected through time series analysis, and an arbitrary prediction model was created and compared with coastal waste monitoring statistics of the marine environment information portal. As a result of the study, it was confirmed that the weights vary for each variable applied to the prediction of marine waste generation by region and season. Since this study was conducted based on statistical data, there was a limit to measuring the accuracy of weights for each variable. If further research is conducted based on field survey data in the future, it is expected that a reliable marine waste generation prediction model will be created.

This paper presents synchronization of LTV (Linear Time-Varying) MAS (Multi-Agent Systems) with heterogeneous time-varying disturbances under a fixed, connected, and undirected communication network. All the agents can collect only relative state information from their neighborhoods. To achieve synchronization of the MAS, an integral control scheme is proposed based on relative state information between agents.

1948년 정부수립 이후 현재까지 국가발전을 추구하는 과정에서 한국의 행정은 어떠한 역할을 하였는가? 그 과정에서 행정은 어떠한 변화를 겪었고, 어떤 특성이 지속되었는가? 이와 같은 행정의 역할과 변화 및 지속성을 고려할 때, 한국 국가발전의 성격과 그 변화는 어떻게 정의될 수 있을 것인가? 이 연구에서는 자본주의 국가기구론의 시각에서 1948년부터 2016년까지의 국가기능별 국가기구의 규모를 측정하고 그 시기별 변화를 분석함으로써, 위와 같은 연구문제에 답하고자 하였다. 분석 결과, 행정은 국가형성, 압축성장과 민주화, 세계화/시장화라는 국가발전을 위한 과제에 대응해 왔으며, 그 과정에서 전반적으로는 경제발전 및 자본축적을 위한 생산기구의 비중이 높게 나타나면서도, 민주화에 따른 정치기구 성장과 복지수요의 확대에 대응하기 위한 복지기구의 성장이 이루어졌다. 이와 같은 변화를 거쳐 2010년 이후 부터는 현대국가의 주요 기능인 합의, 생산, 통합기구의 비중이 서로 수렴하는 양상이 나타나고 있음이 발견되었다. 이와 같은 분석결과를 바탕으로 이론적 함의와 한국 행정의 미래 역할 지향을 제시하였다. As an institutional foundation of the state, state apparatus has been regarded as one of the decisive factors of the stateness and state development. The institutional characteristics of the state apparatus have influence on public policy orientations as well as organizational structures in the public sector of the state, and, in turn, on economic and social development. In this vein, the purpose of this study is to analyze the changes and continuity of state apparatus and its contribution to the state development in Korea from 1948 to 2016 from the perspective of Marxist state apparatus theory. As a result of the analysis, the administration has responded to challenges of state development such as state-building, economic growth, democratization, and globalization/marketization. In the process of responding the challenges, the portion of production apparatuses which relate to economic development and capital accumulation has been generally high since 1948. In addition, welfare apparatus has grown up to cope with the expansion of public welfare service demand since 1997. Political apparatus also has increased since 1987 for responding to the pressure of democratization. With experiencing these changes, it is found that the main functions of the modern states such as consensus, production and integration has converged since 2010. Based on the results of this analysis, the theoretical and policy implications are suggested.

저자들은 6개원 전 metagonimiasis로 진단받고 항기생충 제제로 치료받은 35세 여자 환자가 복통을 주소로 재입원하여 호산구성 위장관염에 의한 장천공으로 부분 소장 절제술을 시행받은 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Eosinophilic gastroenteritis is a rare disorder, characterized by increased eosinophil count and eosinophilic infiltration in gastrointestinal organ. Its etiology is unknown, but affected by parasitic infestation, collagen disorder, malignancy and allergic disorder. There have been several reports all over the world that Eustoma rotundum, Schistosomiasis, Ancylomastoma and Ascaris are the sources of parasites occurring eosinophilic gastroenteritis. But the reports and Ascaris are the sources of parasites occurring eosinophilic gastroenteritis. But the reports on Metagonimus yokogawai have not presented yet. We experienced a case of metagonimiasis with a presentation of small bowel perforation by eosinophilic enteritis. A 35-year-old woman was admitted to the hospital because of epigastric pain. Six months ago, she had been treated as metagonimiasis. This time she took antiparasitic agent again, but abdominal pain was aggravated and perforation of small bowel was detected. The pathologic finding of resected small bowel showed perforation and obstruction with diffuse and dense eosinophilic infiltration.
