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.

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.

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.

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,김영숙,Lee, Hye-Jin,Kim, Young-Suk 중소기업융합학회 2020 융합정보논문지 Vol.10 No.7

본 연구는 한국 중·장년의 저작 문제와 삶의 질의 관련성을 알아보고자 실시하였다. 제6기 국민건강영양조사 자료에서 만 40세 이상 64세 이하의 중·장년 중 건강관련 삶의 질을 알아보는 EQ-5D 지수 및 구강건강 상태에 대한 설문에 응답한 7,125명이 최종 분석대상이 되었다. 대상자의 삶의 질의 평균은 0.96점이었으며 이를 기준으로 삶의 질이 낮은 그룹과 높은 그룹으로 분류하여 저작문제와의 관련성을 분석하였고, 분석은 SPSS 20.0 프로그램을 이용하였다. 저작문제가 있는 그룹에서 낮은 삶의 질의 비율은 41.9%로 저작문제가 없는 그룹(24.4%)보다 유의하게 높았다. 로지스틱 회귀분석을 이용하여 저작문제가 없는 그룹을 기준으로 문제가 있는 그룹에서의 낮은 삶의 질의 비율을 분석하였다. 일반적 특성과 구강건강상태를 보정했을 때 저작문제가 있는 그룹에서 낮은 삶의 질의 비율은 1.77배(95% CI: 1.53-2.06)로 분석되어 저작 문제는 삶의 질과 유의한 관련성이 있음이 확인되었다. 다양한 연령층을 대상으로 건강관련 삶의 질에 관련성이 있을 것으로 예측되는 구강의 요인들을 반영한 연구가 필요하다. The purpose of this study was to investigate the relationship between mastication problems and quality of life among middle-aged Koreans. The study used data from the 6^th Korea National Health and Nutrition Examination Survey(KNHANES VI). Data on 7,125 respondents aged 40 to 64 were analyzed to evaluate quality of life as measured by the Euro Quality of Life-5D(EQ-5D) index and mastication problems. Quality of life was classified as either low or high based on 0.96. The data were analyzed using SPSS 20.0. The prevalence of low quality of life was significantly higher in the group with mastication problems, at 41.9%, than in the group with no mastication problems(24.4%). After adjusting the general characteristics and oral health status, the odds of a lower quality of life were higher in the those with mastication problems, at 1.77 (95% CI: 1.53-2.06), than in those with no mastication problems. Mastication problem was significantly related to the quality of life. The studies are needed to reflect the oral factors in diverse age groups.

Li[Ni_0.3Co_0.4Mn_0.3]O₂ 양극물질의 Li-La-Ti-O코팅 효과

Li(Ni, Co, Mn)$O_2$ has been known as one of the most promising cathode materials for lithium secondary batteries. However, it has some problems to overcome for commercialization such as inferior rate capability and unstable thermal stability. In order to address these problems, surface modification of cathode materials by coating has been investigated. In the coating techniques, selection of coating material is a key factor of obtaining enhanced properties of cathode materials. In this work, we introduced solid electrolyte (Li-La-Ti-O) as a coating material on the surface of $Li[Ni_{0.3}Co_{0.4}Mn_{0.3}]O_2$ cathode. Specially, we focused on a rate performance of Li-La-Ti-O coated $Li[Ni_{0.3}Co_{0.4}Mn_{0.3}]O_2$ cathode. Both bare and Li-La-Ti-O 2 wt.% coated sample showed similar discharge capacity at 0.5C rate. However, as the increase of charge-discharge rate to 3C, the coated samples displayed better discharge capacity and cyclic performance than those of bare sample.

군집 특정 변량효과를 포함한 유한 혼합 모형의 베이지안 분석

이혜진,경민정,Lee, Hyejin,Kyung, Minjung 한국통계학회 2017 응용통계연구 Vol.30 No.1

대량의 데이터에 있어 전반적인 특성 및 구조를 파악하는데 유용하기 때문에 다양한 분야에서 군집분석을 사용하고 있다. Dempster 등 (1977)에서 정의된 expectation-maximization(EM) 알고리즘은 가장 보편적으로 사용되는 군집분석 방법이다. 선형모형의 유한혼합물(finite mixture of linear model) 기법 또한 군집분석 방법 중 많이 사용되는 방법이며 베이지안 군집방법은 Bernardo와 Giron (1988)이 군집에 대한 가중치 확률만 모를 경우 처음 적용하였다. 우리는 이 연구에서 일반적인 선형모형의 유한혼합물이 아닌 군집특정(cluster-specific) 변량효과를 모형에 포함하여 베이지안 분석방법인 깁스표집법(Gibbs sampling)을 사용한다. 제안한 모형의 특성 및 표집법에 대하여 설명하였고 모의실험 및 실제 데이터 분석을 통하여 모형의 유용성을 파악하였다. Hurn 등 (2003)의 CO2 데이터에 모형을 적용하여 변량효과가 없는 모형, 개체특정(subject-specific) 변량효과 모형과 비교하였다. Clustering algorithms attempt to find a partition of a finite set of objects in to a potentially predetermined number of nonempty subsets. Gibbs sampling of a normal mixture of linear mixed regressions with a Dirichlet prior distribution calculates posterior probabilities when the number of clusters was known. Our approach provides simultaneous partitioning and parameter estimation with the computation of classification probabilities. A Monte Carlo study of curve estimation results showed that the model was useful for function estimation. Examples are given to show how these models perform on real data.

Many companies around the world are applying CMMI to improve the organization's ability to perform projects, and many others are pushing to obtain CMMI certification as more and more of them are offered as preconditions for participation in projects or supply product. Organizations with high maturity such as CMMI Level 4~5, analyze the accumulated R&D data of the organization and establish the performance management model so that R&D performance is continuously managed. So this paper shows the R&D performance management model made by LIGNex1 which is certificated with CMMI Level 5 organization and the case applied to the project, including its effectiveness.
