Tuberculosis still ranks as one of the three most important infectious diseases in the world in terms of morbidity and mortality. In Korea, an increased incidence of tuberculosis has been observed in recent years. With the resurge of tuberculosis, extrapulmonary tuberculosis has increased, too. From this point of view, tuberculous arthritis affecting knee is rare in all forms of tuberculosis, but we can consider tuberculous arthritis in patients with osteomyelitis. We report the case of a 14-month-old male child who presented with fever and swelling on the left knee joint. Histologic examination of knee joint fluid showed consistent with tuberculosis. Ziehl-Neelsen stain of joint fluid was positive for acid-fast bacilli(AFB). The outcome was favorable after treatment with anti-tuberculosis medication. Because clinical signs and symptoms of musculoskeletal tuberculosis in children is more indolent, we can misdiagnose or delay diagnosis. The diagnosis of tuberculous arthritis can be elusive, necessitating a high index of suspicion. 국내에서는 아직도 소아연령에서 결핵 감염이 적지 않게 존재하기 때문에 폐외 결핵 환자가 발생될 위험도 지속적으로 존재한다. 이런 측면에서 폐외 결핵의 하나인 골관절 결핵은 매우 드물기는 하나, 관절염을 주소로 내원한 환자의 원인으로 고려해 볼만하다. 나이 어린 소아에서는 증상과 징후가 비특이적이기 때문에 오진이나 진단 지연이 우려되므로, 항생제 치료에 잘 반응하지 않는 관절염 환자에서는 결핵성 골관절염에 대한 진단과 치료를 시도하는 것이 중요하다.

김남천의 『사랑의 水族館』에 나타난 '현대'의 성격과 '현대청년'

이혜진(Lee Hye-Jin) 부산대학교 한국민족문화연구소 2006 한국민족문화 Vol.27 No.-

Aquarium of Love written by Nam-cheon Kim is a novel that was published serially from 1939 to 1940 in Chosun Ilbo. It features the characteristics of modern times that isolates the main character. The author also delineated them in his previous work. While Gwang-joon Kim, brother of Gwang-ho Kim, who ended up in dying of acute tuberculosis after abandoning his old-style wife and cohabiting together with a barmaid was .1 prototype of previous generation that implied the background of the times when the ideology of the past socialists collapsed, Gwang-ho Kim, the main character of this work, represents "the characteristics of modern times". Nam-cheon Kim already showed his interest in the way of the world and public morals through the theories of complaint literature and view literature. Accordingly, his delineation of the characters including Gwang-ho Kim and Gyeong'-hee Lee is just a complaint about and view of the then social reality, and the features of their living were the epitome of the social reality of the times. In this work, Nam-cheon Kim explores the love, belief, the way of the world, and public morals of young people who represent "the characteristics of the times" and are represented by Gwang-ho Kim and Gyeong-hee Lee. Outwardly, however, the story progresses with a focus on the plot of conflicts and reconciliation that arise in the course of love and marriage of Gwan-ho Kim and Gyeong-hee Lee. Furthermore, since the real time from 1939 to 1940 and the internal time of the story coincide, the work fully reproduces the sense of reality of the times. The reason why Nam-cheon Kim positively delineates the new senses of "modernized young people" is that vogue is closely associated with productive relationship and it is a means to sensitively view the public morals of 'modern times'.

이혜진,한일기,이정일,김문덕,Lee, Hye-Jin,Lee, Cheng-Ming,Han, Il-Ki,Lee, Jung-Il,Kim, Moon-Deock 한국진공학회 2007 Applied Science and Convergence Technology Vol.16 No.4

양자폭포레이저에서 활성영역의 모의실험을 위하여 Runge-Kutta 방법과 shooting 방법을 이용하여 슈뢰딩거 방정식의 해를 구하였다. 활성영역의 두께 변화에 대하여 발진파장, 포논공명 에너지, 분극행렬요소 (dipole matrix element) 등의 특성변화를 관찰하였고, 이로부터 양자폭포레이저를 위한 에피성장에서 허용될 수 있는 최소한의 두께 정밀도를 제안하였다. For the simulation of active region in the quantum cascade lasers (QCL), we solved Schrodinger equation utilizing Runge-Kutta method and Shotting method. Wavelength, phonon resonant energy, and dipole matrix element were simulated with the variation of active region thickness. As a result of such simulation, it was suggested the tolerance range of epi-layer thickness error when 3-quantum well QCL structures are grown.

이혜진,이수진,이연숙,Lee, Hye-Jin,Lee, Soo-Jin,Lee, Yuen-Sook 한국주거학회 2012 한국주거학회 논문집 Vol.23 No.2

In Korea, apartment complexes are built according to the social strata for which they are intended to house, thus the buildings tend to separate society both physically and even visually. Because of the sense of social exclusion this has caused the government has conceived a plan to develop a "social-mix" apartment complex master plan. Perhaps the foremost example of this type of plan is the Seoul Eunpyeong New Town. This study examines how resident's perception of the social mix plan has evolved, and also attempts to better understand the effectiveness of the government's attempt at social integration. The result shows that the perception of social-mix housing has improved after residents moved into the Eunpyeong New Town and that people responded positively to the concept of actually mixing residents socially. From the result, we can see that the visually unexposed environmental elements of rental housing and socials exclusion which was felt in the past has been reduced to a certain extent. However, residents living in solid-lot apartments have a negative reaction to social mixing especially when they are in the same building. Therefore, to achieve better social integration in a socially-mixed apartment complex, we need now to change the perception toward socially mixed housing among the residents living in solid-lot apartment buildings.

이혜진,Lee, Hye-Jin 한국낙농육우협회 2010 낙농·육우 Vol.30 No.11

수도권을 중심으로 근교농업으로 발달한 낙농업이 점차 지역의 도시화 됨에 따라 경기도 축산 농가들의 환경을 더욱 어렵게 하고 있다. 특히나 수도권 지역의 낙농가들은 도시화로 인해 후보목장부지 물색에 실패하거나 후계자를 세우지 못한 목장 등이 농장폐업에 나서면서 2006년부터 2009년까지 매년 600여 농가가 자신의 쿼터를 매각하고 목장을 정리했다. 이러한 상황 속에서도 낙농업을 3대째 이어오면 기업승계로 고군분투하고 있는 목장이 있다.

강의 평가 사례 연구

이혜진,문일,홍대식,Lee Hye-Jin,Moon Il,Hong Dae-Sick 한국공학교육학회 2000 공학교육연구 Vol.3 No.1

본 연구에서는 현재 실시되고 있는 강의 평가제의 실례를 통해서 강의 평가제가 교수들에게 미칠 수 있는 영향을 검토하였다. 5학기 동안 동일 학과의 강의 평가를 분석한 결과, 각 교수별로는 차이가 있었지만 평균점수는 전반적으로 향상되었고 어느 기간이 지나면 더 이상 진전이 없는 것이 관찰되었다. 이러한 결과를 기반으로 강의 평가의 실시 목적에 부합되는 결과 활용의 효율성을 높이기 위해 수행되어야 할 몇 가지 개선책을 제시하였다. 또한 외국 대학의 설문 유형을 살펴봄으로써 우리 나라 대학에서 실시하는 강의 평가제의 향후 개선 방향을 제시하였다. 결과적으로, 강의 평가제는 신중하게 운영되어야 하며, 반드시 교수 자신의 발전을 위해서만 사용되어야한다. 미국의 경우 강의 평가제가 교수의 평가 수단으로 사용되면 많은 부작용이 따른다는 것을 알 수 있었다. We have analyzed the result of course evaluation in a department for five semesters. The results of the students' course evaluation varied on individual lecturer, however the average score was improved initially and it was saturated after several semesters. Based on these results, we suggest several effective methods of using the evaluation results. We also suggest to study more in improving the questionnairs of the evaluation format to receive students' positive responses for the better course in the future. As a conclusion, the course evaluation system must be carefully introduced and it should be used only for improving the course itself. When this system is applied to evaluating the capability of lecturers, lecturers would easy their requirements and standards of the education and this causes a lot of problems in the case of the USA.

The purpose of this study was to compare of the effectiveness of tooth bleaching with different hydrogen peroxide concentrations and light activated plasma arc on extracted premolar tooth The 100 specimens were stained using the CEYLON black tea. Among of them 60 specimens were selected by lightness values (*L) and were classified into five groups (n=12): Group Ⅰ, Distilled water; Group Ⅱ, 5% hydrogen peroxide gel ; GroupⅢ, 5% hydrogen peroxide+plasma arc; Group Ⅳ, 15% hydrogen peroxide; GroupⅤ, 15% hydrogen peroxide +plasma arc. Specimens were bleached until 4 times (60 min). The color change (ΔE*) of specimens was measured after stained and each bleaching time by Shade Eye-NCC. The samples were analyzed qualitatively by evaluating morphological changes in the SEM images, microhardness and quantitatively by using roughness parameters (Ra). The acquired data was analyzed by paired t-test and one-way ANOVA followed by Tukey s multiple test for variable at a 0.05 significant level. The color changes (ΔE*) significantly increased after bleaching in all groups (p<0.05). Microhardness (VHN) significant decreased after bleaching in all groups AFM and SME images exhibited that the surfaces of specimens became roughed after bleaching. Especially, Group of hydrogen peroxide with plasma arc showed more rougher than hydrogen peroxide without plasma arc in SEM. This study suggested that hydrogen peroxide with plasma arc may be better tooth whitening effects than only hydrogen peroxide.

The oxidative modification of low density lipoprotein(LDL) has been implicated in the development of atherosclerosis. Oxidized LDL(oxLDL) is captured into macrophage and stimulates to form macrophage foam cell. And it can induce an inflammation and smooth muscle proliferation in atherosclerotic plaque. Objective : In this study, we aimed to investigate the effect of Bupleuri radix(SH) on the foam cell formation, a critical initiation stage of atherosclerosis. Methods : To achieve the goal, we examined the effect of SH on LDL oxidation, nitric oxide production in RAW264.7, and the effect of SH on cupuric sulfate-induced cytotoxicity, LDH release, and macrophage activity. Results : SH inhibited the formation of oxidized LDL from native LDL in RAW264.7 cell culture, and decreased the release of LDH from cupric sulfate-stimulated RAW264.7 cell. In other experiments, SH activated RAW264.7 cell, and prolonged the survival time, and inhibited foam cell formation induced by oxLDL in Raw 264.7 cells. Conclusion : These results showed that SH might prevent atherosclerosis by controlling the early stages of foam cell formation.
