Barrett`s esophagus is a metaplasia of the esophageal epithelium of any Length, such that normal squamous epithelium is replaced by specialized columnar epithelium with goblet cells. It is important to diagnose and survey Barrett`s esophagus because it is believed to be the major risk factor for development of esophageal adenocarcinoma. However, the prevalence of Barrett`s esophagus in Korea is Low. Mixed connective tissue disease (MCTD) is a systemic disorder in which patients have combinations of the clinical features of systemic Lupus erythematosus, systemic sclerosis, and polymyositis. Although gastroesophageal reflux disease is common in esophageal involvement in MCTD, Long-segment Barrett`s esophagus in MCTD has not been reported in Korea. We report here a 15 cm-Long segment of Barrett`s esophagus extending to the proximal esophagus in a female patient who has had MCTD for 2 years, and we review the Literature.

This article is for the research and analysis of the particular case and figure out the characteristic of people gathering space. Also, by the comparing naturally made public space and newly made space, this article will investigate that which elements are required for the activation of public space.

시대와의 이단적 논쟁 : 『우리들』의 이념적 기원들

문준일(Moon Jun IL) 한국노어노문학회 2009 노어노문학 Vol.21 No.2

자먀찐의 『우리들』은 디스토피아소설이다. 유토피아의 이념을 부정하는 디스토피아는 내부에 유토피아에 대한 이념적 논쟁을 담을 수밖에 없다. 그래서 『우리들』은 이념소설의 구조를 가지고 있다. 작가는 이 소설로 당대의 이념과 시대와의 이단적인 이념논쟁을 벌인 것이다. 이념적 논쟁은 텍스트 속에서 프롤레트쿨트의 문학적 관습과 이념에 대한 패러디로 나타난다. 당시 세계개조에 대한 주체로서의 집단에 대한 숭배를 프롤레타리아 시인들의 작품 속에서 자주 찾아볼 수 있었다. 이 집단주의는 작품의 제목 “우리들”로 패러디된다. 자먀찐이 『우리들』에서 벌인 논쟁의 가장 기본적인 대상은 알렉세이 가스쩨프였다. 그는 집단에 산업화의 원리가 적용된 기계화된 집단을 주장하였다. 그래서 그 구성원들은 감정과 표현, 영혼도 없는 알파벳과 숫자로 이름 붙여지는 기계와도 같은 존재가 된다. 단일제국의 번호들에서 가스쩨프의 이론은 정확히 표현된다. 그리고 과학주의, 진보에의 맹신, 그리고 우주주의 등 그들의 이념들은 『우리들』속에서 중심적인 이미지들로서 등장한다. 이러한 『우리들』의 이념적 기원들은 결국 세계 개조가 과연 가능한 것인지, 그 권리가 우리에게 있는 것인지, 이성만능주의의 사회가 이를 곳은 어디인지 가장 본질적인 질문으로 우리를 이끈다.

The estimation filter in radar systems must track targets' position within low tracking error. In the Multi-Function Radar(MFR), ${\alpha}-{\beta}$ filter and Kalman filter are widely used to track single or multiple targets. However, due to target maneuvering, these filters may not reduce tracking error, therefore, may lost target tracks. In this paper, a target tracking filter based on particle filtering algorithm is proposed for the MFR. The advantage of this method is that it can track targets within low tracking error while targets maneuver and reduce impoverishment of particles by the proposed resampling method. From the simulation results, the improved tracking performance is obtained by the proposed filtering algorithm.

Bupivacaine 과 Morphine 의 지속적 경막외 주입 중에 발생한 호흡정지

이준학(Jun Hak Lee),이기남(Ki Nam Lee),문준일(Jun 대한통증학회 1995 The Korean Journal of Pain Vol.8 No.2

Combined infusion of local anesthetics and opioids has been a common method for providing postoperative analgesia. Complications that can occur with this method include pruritus, nau- sea and vomiting, urinary retention, hypotension, and both early and late respiratory depres- sion. Late respiratory depression is a rare but feared complication to epidural opioid therapy. We experienced a case of respiratory arrest during epidural infusion of bupivacaine and morphine.

목적: 엔테카비어는 HBV에 강력한 항바이러스 효과가 있으며 내성이 드물게 발생한다. 비대상성 간경변증 환자에서 엔테카비어의 장기치료효과에 대한 연구결과는 많지 않다. 이에 저자들은 B형간염 바이러스에 의한 비대상성 간경변 환자를 대상으로 엔테카비어 치료효과와 엔테카비어 효과를 예측할 수 있는 인자를 알아보고자 하였다. 대상 및 방법: 2006년 11월부터 2011년 1월까지 아주대학교 병원에 내원한 만성 B형 간염으로 인한 비대상성 간경변 환자 중 6개월 이상 엔테카비어 치료를 받은 45명을 후향적으로 조사하였다. 대상 환자는 전 예에서 HBV DNA양성이고 CTP score가 8점 이상이며, HBeAg은 17 명에서 양성이었다. 엔테카비어 치료 3개월마다 HBV DNA, CTP score 및 AST, ALT, 빌리루빈, 알부민, 프로트롬빈 시간, 크레아티닌 등을 검사하였다. 결과: 엔테카비어 투여 12개월 후 HBV DNA는 45명중 40명 (88.9%)에서 음전되었다. CTP 점수의 호전을 보인 환자는 45 명중 32명(71.1%)이었으며, 2명(4.4%)은 악화를 보였고 11명 (24.4%)은 유지하거나 1점 감소를 보였다. 약물 투여 전HBeAg이 양성이었던 17예 중에서 9명(52.9%)이 음성전이를 보였다. 전체 환자에서 12개월간 엔테카비어 치료 후 빌리루빈, 알부민, 프로트롬빈 시간이 치료 전에 비해 정상화되었다. 전체 환자에서 CTP score, MELD score는 각각 투약 전 10.1 (±2.0), 13.48 (±4.05)에서 엔테카비어 투여 12개월 후 각각 7.24 (±2.0), 9.68 (±4.85)로 감소하였다. 결론: Entecavir는 비대상성 간경변 환자에서 안전하게 간기 능을 호전시켰다. INR이 엔테카비어 치료효과를 예측할 수 있는 인자로 관찰되었다. Background/Aims: Entecavie (ETV) has a potent antiviral effect and low rates of resistance in hepatitis B virus (HBV) and is the first-line monotherapy in patients with HBV-related decompensated cirrhosis. We evaluated the efficacy of 12 months treatment with ETV and tried to determine predictive factors of response. Methods: Forty-five consecutive decompensated cirrhotic patients who received ETV (0.5 mg/day) for more than six months were included. All patients were positive for HBV DNA, and the Child-Turcotte-Pugh (CTP) scores were over 8 point. Seventeen patients were HBeAg-positive. CTP score, model for end-stage liver disease (MELD) score, serum markers of liver function and HBV DNA were assessed every 3 months. Results: ETV treatment for 12 months resulted in improvement of CTP and MELD scores. Pre-treatment mean CTP and MELD score were decreased from 10.1 (±2.0) and 13.48 (±4.05) to 7.24 (±2.0) and 9.68 (±4.85) at 12 months, respectively. The 1-year cumulative rates of HBV DNA negativity and HBeAg loss were 88.9% and 52.9%, respectively, by intention-to-treat analysis. Thirty-two (71.1%) showed improvement in CTP score. Eleven patients did not show change, and 2 patients got worse. The AST/ALT, albumin, bilrubin, prothrombin time were significantly normalized within six months. The good responder group had high level of prothrombin time than the poor responder group (p=0.004). Conclusions: Our result shows that entecavir can improve liver function in about 70% of patients with HBV related decompensated liver cirrhosis. INR may be a predictive factor of good response with entecavir in these patients.

SPM-based Data Storage 시스템을 위한 강인 제어 시스템 설계 방식을 이용한 외란 관측 제어기 설계

文俊(Jun Moon),李忠宇(Choong Woo Lee),鄭正周(Chung Choo Chung) 대한전기학회 2009 전기학회논문지 Vol.58 No.1

In this paper, we apply the robust disturbance observer (DOB) to a SPM-based data storage (SDS) system. In the SDS system, coupling dynamics and parameter uncertainties are obstacles to the precision tracking control. Although the DOB is known to be an effective method to reject disturbances, there has been no systematic design approach to how to design DOB parameters. In this paper, the robust DOB is formulated based on the robust stabilization of normalized coprime factor plant description and the H∞ loop shaping method. From the simulation and experimental results. the improved robustness and performance are obtained by the proposed robust DOB.

Robust Control over Unreliable Communication Channels with Unreliable Acknowledgements

Jun Moon(문준) 제어로봇시스템학회 2019 제어·로봇·시스템학회 논문지 Vol.25 No.6

In this paper, we consider the robust (H∞) control problem for linear time-invariant systems over unreliable communication channels that are subject to packet losses from sensors to the controller and from the controller to the actuators. Moreover, the acknowledgments of control packet transmissions are also sent over reverse unreliable communication channels, which is known as the quasi-TCP model. The robust control problem is formulated within a stochastic zero-sum dynamic game framework, from which we obtain an H∞ controller that minimizes the worst-case cost function in the presence of an adversary in the dynamical system. We characterize a set of existence conditions of the H∞ controller in terms of the disturbance attenuation parameter γ and packet loss rates. For the least disturbance attenuation scenario (γ →∝), we show that the H∞ control system converges to the corresponding LQG system. We also show that the H∞ controller for the TCP- and UDP-cases can be arrived at as appropriate limits of the solution for the quasi-TCP problem. Numerical examples are presented to illustrate the theoretical results.
