Sangyong Lee,Wonki Park,Kyongwon Min,Byong-Deok Choi,SungChul Lee 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7

In this paper, a sigma-delta (Σ-Δ) analog-to-digital converter (ADC) is presented with 14.97-bit accuracy. The ADC is composed of fourth-order single-loop single-bit sigma-delta (Σ-Δ) modulator and digital decimation filter. The modulator with an oversampling ratio of 128 and a signal bandwidth of 4㎑ has been designed in a 0.35㎛ CMOS technology. The designed decimation filter has been verified using an FPGA. The Σ-Δ modulator consumes 3㎽ from a single 3.3V supply voltage.

Kim, Eugene,Lee, Huisu,Kim, Hyun Sook,Won, Sulmui,Lee, Eu Kyoung,Kim, Hwan Soo,Bang, Kyongwon,Chun, Yoon Hong,Yoon, Jong-Seo,Kim, Hyun Hee,Kim, Jin Tack,Lee, Joon Sung The Korean Pediatric Society 2013 Clinical and Experimental Pediatrics (CEP) Vol.56 No.11

Purpose: The aim of the present study was to investigate the differences in lower airway inflammatory immune responses, including cellular responses and responses in terms of inflammatory mediators in bronchoalveolar lavage fluid (BALF) and the airway, to rhinovirus (RV) infection on asthma exacerbation by comparing a control and a murine asthma model, with or without RV infection. Methods: BALB/c mice were intraperitoneally injected with a crude extract of Dermatophagoides farinae (Df ) or phosphate buffered saline (PBS) and were subsequently intranasally treated with a crude extract of Df or PBS. Airway responsiveness and cell infiltration, differential cell counts in BALF, and cytokine and chemokine concentrations in BALF were measured 24 hours after intranasal RV1B infection. Results: RV infection increased the enhanced pause (Penh) in both the Df sensitized and challenged mice (Df mice) and PBS-treated mice (PBS mice) (P<0.05). Airway eosinophil infiltration increased in Df mice after RV infection (P<0.05). The levels of interleukin (IL) 13, tumor necrosis factor alpha, and regulated on activation, normal T cells expressed and secreted (RANTES) increased in response to RV infection in Df mice, but not in PBS mice (P<0.05). The level of IL-10 significantly decreased following RV infection in Df mice (P<0.05). Conclusion: Our findings suggest that the augmented induction of proinflammatory cytokines, Th2 cytokines, and chemokines that mediate an eosinophil response and the decreased induction of regulatory cytokines after RV infection may be important manifestations leading to airway inflammation with eosinophil infiltration and changes in airway responsiveness in the asthma model.

선천성 매독은 산전진찰로 예방할 수 있음에도 불구하고, 여전히 문제가 되고 있다. 최근에는 선천성 매독과 관련된 혈뇨나 폐렴이 보고된 증례가 없었으나 저자들은 적절한 산전치료를 받지 못한 산모에게서 태어난 22일된 남아에게서 발생한 선천성 매독에 동반된 신증후군과 폐렴의 증례를 보고한다. 선천 매독의 진단은 혈청학적 검사로 확진하였고, 환아는 페니실린 G 치료를 받고 회복되었다. 신생아에게서 임상증상은 매우 불확실할 수 있어, 질환에 대한 인식이 지연 될 수 있다. 따라서 선천성 매독의 예방에는 철저한 산전관리가 필수적이다. 만약 산모가 적절한 산전진찰을 받지 않았을 경우에는 신속한 혈청학적 진단이 반드시 시행되어야 할 것이다. Although congenital syphilis can be prevented with prenatal screening, the disease remains problematic. Currently, there are no cases that describe hematuria and pneumonia related to congenital syphilis. We report a case of congenital syphilis that involved nephrotic syndrome and pneumonia alba in a 22-day-old male infant whose mother did not receive adequate prenatal care. The congenital syphilis diagnosis was confirmed with a serologic test and the patient recovered with penicillin treatment. Clinical findings may be subtle in neonates and delayed recognition occurs frequently, thus complete prenatal screening is critical for congenital syphilis prevention. Immediate serologic testing should be performed to obtain a differential diagnosis if an infant is delivered by a mother that has not received appropriate prenatal examinations.

DR-LSTM: Dimension reduction based deep learning approach to predict stock price

Lee Ah-ram,Ahn Jae Youn,Choi Ji Eun,Kim Kyongwon 한국통계학회 2024 Communications for statistical applications and me Vol.31 No.2

In recent decades, increasing research attention has been directed toward predicting the price of stocks in financial markets using deep learning methods. For instance, recurrent neural network (RNN) is known to be competitive for datasets with time-series data. Long short term memory (LSTM) further improves RNN by providing an alternative approach to the gradient loss problem. LSTM has its own advantage in predictive accuracy by retaining memory for a longer time. In this paper, we combine both supervised and unsupervised dimension reduction methods with LSTM to enhance the forecasting performance and refer to this as a dimension reduction based LSTM (DR-LSTM) approach. For a supervised dimension reduction method, we use methods such as sliced inverse regression (SIR), sparse SIR, and kernel SIR. Furthermore, principal component analysis (PCA), sparse PCA, and kernel PCA are used as unsupervised dimension reduction methods. Using datasets of real stock market index (S&P 500, STOXX Europe 600, and KOSPI), we present a comparative study on predictive accuracy between six DR-LSTM methods and time series modeling.

북한이탈주민 직장적응 실태 분석과 제언

이지영 ( Lee Jiyoung ),최경원 ( Choi Kyongwon ) 대한정치학회 2021 大韓政治學會報 Vol.29 No.1

북한이탈주민에게 대한민국에서의 성공적인 정착은 곧 직장적응이 수반된 안정된 취업이다. 그러나 대부분의 북한이탈주민에게 안정된 취업과 직장생활은 요원하기만 하다. 북한이탈주민의 취업률은 여전히 낮으며 정부의 취업지원정책이 다양해지고 지속적으로 개선되고 있으나 실제 북한이탈주민들이 체감하는 사회적응교육 및 직장생활에 대한 만족도는 그리 높지 않다. 남한의 노동시장에서 북한이탈주민에 대한 편견, 선입견과 차별은 상존하며 북한이탈주민이 한국사회에 정착하는 것은 여전히 어려움이 많다. 이에 북한이탈주민의 직장적응 실패원인을 실증적으로 분석하고 해결방안을 제시하는 것이 본 연구의 목적이다. 본 연구는 표본설정에 있어서 고용주 입장에서의 북한이탈주민 평가와 북한이탈주민 취업자의 직장적응 실태에 대한 평가를 동시에 분석함으로서 기존의 다른 연구와 차별성을 갖고 있다. 이러한 분석 결과를 토대로 북한이탈주민의 안정적 취업과 직장적응을 위한 정부의 북한이탈주민 정착지원정책의 개선방향을 네 가지로 제시한다. 첫째, 하나원, 하나센터에서 진행되는 사회적응 및 직장적응교육은 북한이탈주민 본인의 적성과 능력에 맞는 현장체험 중심의 직업적응교육으로 이어져야 하며, 충분한 기간동안 재사회화를 위한 단계적 맞춤형 과정으로 진행되어야 한다. 둘째, 고용노동부나 한국산업인력공단의 책임과 역할을 강화하여 직업훈련기관들에서는 북한이탈주민의 자활·자립을 돕는 맞춤형 직업기술교육이 실시되어야 한다. 셋째, 정부와 지방자치단체, 시민단체와 하나센터 등이 협력적 거버넌스를 구축하여 북한이탈주민이 실제 취업과정착에 필요한 사회적응교육, 정치체제교육, 경제관리교육을 평생교육의 관점에서 체계적으로 온라인-오프라인 교육을 받을 수 있도록 지원해야 한다. 넷째, 북한이탈주민의 고용기회 확대와 취업지원체계 재구축을 통해 안정된 일자리를 지속적으로 창출해나가야 한다. For North Korean defectors, a successful settlement in South Korea is a stable job involving workplace adaptation. For most North Korean defectors, however, stable employment and work life are only a long way off. The employment rate of North Korean defectors is still low, and the government's employment support policy is diversifying and improving, but the satisfaction level of social adaptation education and work life felt by North Korean defectors is not sufficient. Prejudice and discrimination against North Korean defectors exist in the South Korean labor market, and North Korean defectors are still in many difficulties in settling in South Korean society. Therefore, the purpose of this study is to analyze the causes of North Korean defectors' failure to adapt to work and present solutions. This study is different from other existing studies by simultaneously analyzing the evaluation of North Korean defectors from the perspective of employers and the status of North Korean defectors' employment at work. Based on the results of these analyses, four directions are presented to improve the government's policy to support North Korean defectors' settlement for stable employment and workplace adaptation. First, social adaptation and workplace adaptation education at North Korean Refugee Settlement Support Office should lead to job adaptation education centered on field experience that suits the aptitude and ability of North Korean defectors, and should be conducted as a step-by-step customized course for re-socialization for a sufficient period. Second, by strengthening the responsibilities and roles of the Ministry of Employment and Labor and the Korea Industrial Manpower Corporation, vocational training institutions should provide customized vocational technology education to help North Korean defectors live on their own. Third, the government, local governments, civic groups, and North Korean Refugee Settlement Support Office should establish cooperative governance to help North Korean defectors receive online and offline education systematically from the perspective of lifelong education in terms of social adaptation education, political system education, and economic management education necessary for actual employment and settlement. Fourth, stable jobs should be created continuously by expanding employment opportunities for North Korean defectors and rebuilding the employment support system.

정보보호 사기진작 결정모델 연구

김경원(Kyongwon Kim),임종인(Jong In Lim),이경호(Kyung-Ho Lee) 한국정보보호학회 2015 정보보호학회논문지 Vol.25 No.4

최근 정보보안 침해사고가 증가함에 따른 정보보호인력의 업무와 책임부담이 가중되면서, 이들의 사기저하 문제가 사회적으로 제기되고 있다. 이를 해결하기 위하여 정부에서도 다양한 정보보호인력 사기진작방안을 마련하고 있으며, 금융사의 경우 자체적으로 사기진작 계획을 세워 금융위원회에 보고할 것을 요구하고 있다. 본 연구에서는 문헌고찰 및 빈도분석을 통하여 정보보호 분야의 16가지 사기수준 결정 변수를 도출하고, 정보보호인력을 대상으로 사기 진작에 중요한 요인이 무엇인지를 실증적으로 분석하였다. 연구결과 정보보호인력의 사기수준 결정요인으로 직무적 특징, 제도적 특징, 관계적 특징 등 3가지 요인을 압축적으로 제시하였으며, 정보보호인력 사기진작 프로그램 운영시 활용할 수 있도록 사기수준 측정모델의 활용방안을 제시하였다. As the number of recent information security incident occurrence increases, more and more workload and liability pressure are given to info-security professionals, which results in decrease of morale level of working groups in the field. In order to solve this problem, Korean government is providing various action plans to improve the morale level of info-security professionals, and also requiring financial companies to submit its own action plan of increasing morale of info-security professionals to Financial Service Agency. For this study, based on the previous studies and relevant professionals’ interviews, we selected 16 critical morale increase variables, and performed survey for empirical analysis. As a result, 3 features; role, system, and relationship were presented as the main factor of morale increasement of info-security professionals. This study also suggests a decision making method of utilizing the developed morale measurement model for individual organizations.
