이경원,정윤섭,권오헌,장인호,윤갑준,김성진 대한감염학회 1993 감염 Vol.25 No.1

Bacteroides fragilis군 세균은 중요한 혐기성 병원균으로 몇가지 항균제에 내성인 균주가 차츰 증가되었고, 그 비율은 지역에 따라 다르다고 보고되어 있다. 이 연구에서는 우리나라의 2개 대학병원에서 1991년에 분리된 257주의 B. fragilis군 세균을 대상으로 15종의 항균제 감수성을 한천희석법으로 시험하였다. 1990년과 1991년에 분리된 세균의 내성율을 비교하면 각각 다음과 같았다 : penicillin G, 94%와 98% ; ticarcillin, 25%와 28% ; piperacillin, 21%와 23% ; cefamandole, 92%와 100% ; cefoxitin, 6%와 4% ; cefotaxime, 33%와 56% ; cefotetan, 28%와 25% ; ceftazidime, 63%와 89% ; ceftriaxone, 36%와 56% ; clindamycin, 24%와 42% ; tetracycline, 85%와 93%, 시험균주 중 imipenem, chloramphenicol 및 metronidazole에 대한 내성 균주는 없었다. Cefotaxime, ceftazidime, ceftriaxone 및 clindamycin에 대한 내성율은 1991년 분리된 균주가 유의하게 높았다. 내성균주의 비율은 B. fragilis가 B. ovatus, B. thetaiotaomicron, B. vulgatus 혹은 B. distasonis 보다 낮았다. 몇가지 항균제에 대한 감수성 균주의 비율은 분리한 병원에 따라서 약간의 차이가 있었다. B. fragilis군 세균의 일부 항균제에 대한 내성율은 차츰 증가되고 있고, 감수성 양상은 시기와 지역에 따라서도 차이가 있으므로 환자 치료를 위한 지침을 세우기 위해 정기적인 항균제 감수성 시험이 필요하다는 결론을 얻었다.

김성진,Kim, Sung-Jin 한국비블리아학회 2013 한국비블리아학회지 Vol.24 No.2

대학도서관은 모바일 웹사이트를 구축하고 모바일 애플리케이션을 개발함으로써 모바일 기기를 통해서도 도서관 서비스에 접근할 수 있는 통로를 제공하고자 노력하고 있다. 이러한 추세 속에서 모바일 서비스의 양적 증가만이 아닌 질적 성장을 위해 모바일 도서관 서비스 이용자들의 요구를 파악할 필요가 있다. 본 연구는 모바일 도서관 서비스를 이용하는 이용자의 이용경험과 요구를 파악함으로써 모바일 도서관 서비스 활성화 방안을 제안하고자 하였다. 이를 위해 모바일 웹과 모바일 앱을 통해 적극적인 모바일 서비스를 제공하고 있는 2개의 대학도서관을 선정하고 재학생 608명을 대상으로 온라인/오프라인 설문조사를 실시하였다. 모바일 도서관 이용빈도 및 목적, 이용/비이용 요인, 접근 경로, 주요 이용 서비스, 서비스 만족도, 불만족요인, 개선사항 등을 조사하였으며, 분석 결과를 기반으로 이용자 관점에서 모바일 도서관 서비스의 활성화 방안을 서비스 개선과 이용률 제고 측면에서 제안하였다. Academic libraries are trying to develop fully mobile web sites and mobile applications so that users can access to their services even using mobile devices. As the mobilization trends of library services increase in quantity, we need to more focus on what mobile services users want, ultimately for the growth with quality. This study seeks to explore users' needs and uses of mobile library services and then suggests solutions for improving the mobile services in academic libraries. This study conducted on and off-line surveys with 608 students from two universities, which have provided active mobile services with both a mobile web site and an application. The questionnaire was designed to elicit information on respondents' frequency of mobile library visit, the purpose of visit, the reason to use/not use, how to access to the services, the preferred types of the services, satisfaction and dissatisfaction factors, and urgently needed improvements. Based on the findings, this study discussed strategies to improve the quality of mobile services and to increase in users' visit.

유기물 기반의 새로운 패터닝 기법과 이를 이용한 신재생 에너지 소자

김성진,Kim, Sung-Jin 한국진공학회 2009 Applied Science and Convergence Technology Vol.18 No.5

유기물 기반의 전자 소자에서 소자간의 전기적인 전류 흐름 및 기생저항 등을 차단하기 위하여 표면 에너지를 이용한 새로운 패터닝 기법을 제안하였다. 소수성의 perfluoro-alkyl fluorosilanes을 플라즈마 이온 에칭을 이용하여 선택적으로 친수성으로 변환한 뒤 wettability 현상을 통해 유기 물질을 자동 패터닝 하였다. 또한 이 기법을 이용하여 $V_{oc}$ (open circuit voltage): 482 mV, $J_{sc}$ (short circuit current density): 2.4 mA/$cm^2$, FF (Fill factor): 0.58, $\eta$ (Efficiency): 0.95 % 의 특성을 보이는 bulk-이종접합 유기 태양 전지 소자를 제작하였다. We report on a new patterning technique for organic functional materials applicable to organic photovoltacis (OPVs). The unconventioal patterning technique, $O_2$ plsama-etching selectively perfluoro-alkyl fluorosilanes, is used for producing a bulk-heterojunction active layer with poly(3-hexylthiophene) as the electron donor and [6,6]-phenyl-$C_{61}$ butyric acid methyl ester as the electron acceptor. The patterning with reduced leakage path and parasitic capacitance suggests a way for fabrication of OPVs with higher energy conversion efficiency.

In this paper, a technique for the quantitative analysis of the noise jamming effect is proposed. This technique based upon the mathematical modeling for noise jammers and the probability theory for random processes analyses the jamming effect by means of the modeling of the relationship among jammer, radar variables and radar detection probability under noise jamming environment. Computer simulation results show that the proposed technique not only makes the quantitative analysis of the jamming effect possible, but also provides the basis for quantitative analysis of the electronic warfare environment.

This study was conducted to use the Bayes approach, which can be applied in various pre-distribution for genomic selection application in the evaluation of Hanwoo carcass traits, as basic data for genomic selection through genetic accuracy and reliability estimation. As for the data used in the analysis, 8,413 DNA collected by various methods from Hanwoo farms nationwide were extracted. The Axiom Bovine 60k version 3(Affymetrix Inc., 2006) SNP panel was used to generate genomic information. Quality control removed SNPs whose SNPs were on sex chromosomes or whose position on chromosomes was not identified, with a total value of more than 64 markers removed, with an SNP call rate of 95% or less, a Minor Allele Frequency(MAF) of 0.01 or less, and a Hardy-Weinberg Equilibrium(HWE). Among the 8,413 with genetic information, duplicate animals, pedigree errors, and animals that did not match dependent variables were removed, and 6,616 reference groups with genotype information were used for analysis. The KPN used in the analysis was extracted using semen, and the DNA was extracted using tissue samples provided by the Korea Institute for Animal Products Quality Evaluation, and in the case of cows, tail hairs were collected, and DNA was extracted and used for analysis. MBV accuracy was estimated to be 0.25 to 0.55, and accuracy is affected by various factors. In the case of clustering, it is considered that a change in MBV accuracy occurs because the composition of the training group and the verification group varies depending on the number of groups and the clustering method. In addition, MBV accuracy changed according to Bayes B and Bayes C methods assuming different prior distributions. Among the Bayesian methods, the accuracy of MBV in Bayes C was higher than that of Bayes B. This is believed to be because the assumption of prior distribution to estimate the SNP effect is different, and considering that there is no SNP with a great effect, Hanwoo slaughter data is quantitative, so it is considered that the genes involved are related to multiple genes, not a specific one. As genotype information was added to the existing phenotype information, the reliability of the Hanwoo carcass traits GEBV increased by 0.243±0.060. In particular, in the group with low reliability, the contribution to estimating the GEBV was low, but the increase in reliability was the highest. It was found that the ranking of genetic evaluation on phenotype data changed due to mixing with MBV. Compared to the GEBV, the Two Step method was more correlated than the Single Step method. Therefore, when using genotype information, the difference between the Single Step and the Two Step is not much different, but when a lot of genotype data is collected in the future, it is considered that there will be a difference in reliability and GEBV.

1980년대 민중문학론의 현재성

김성진 우리말글학회 2018 우리말 글 Vol.79 No.-

This study examined the present meaning of the discourse of people’s literature in the 1980s. Their criticism focused on the workers’ autobiography and reportage that were underestimated compared to modern poetry and novels. They came up with a new argument that goes beyond the idea that the people become the subject of creation or literature has to shape the ideals and struggles of the working class. It is a break away from the one-way communication structure that presupposes the creation of experts and the acceptance of the public and a critique of the custom of thinking about modern literature centering on realistic novels. The discourse of people’s literature emphasized the context of text production and the use of text by acceptor and the acceptor’s activeness. This is analogous to the assumptions of cultural studies. And the discourse of people’s literature sought a new genre that goes beyond the limits of modern literature centering on realistic novels. This is similar to the avant-garde art theory. However, their criticism emphasized the propaganda of literature by idealizing the people as a single subject of historical development. And they were obsessed with the form of realism novel. In this process, the newness in their criticism was extinguished by itself. 본 연구는 1980년대 민중문학론의 현재적 의미를 살펴보았다. 채광석, 김도연, 김명인의 비평 담론은 시나 소설에 비해 과소평가되었던 노동자 수기나 보고 문학에 주목했다. 이들의 주장에는 민중이 본격 창작의 주체가 되었다거나 노동자 계급의 이념과 투쟁을 형상화해야 한다는 것 이상의 문제 의식이 담겨 있다. 그것은 전문가의 창작-대중의 수용이라는 일방향적 문학 소통 구조의 탈피, 장편 소설을 중심으로 문학을 사고하지 않고 새로운 장르를 모색하려는 시도로 요약될 수 있다. 민중문학론은 텍스트가 제작되고 배급되며 수용자에 의해 활용되는 맥락과 문화 수용자의 능동성을 강조했다는 점에서는 문화연구의 문제 의식을, 리얼리즘 장편 소설을 중심으로 하는 근대 문학의 한계를 넘어선 새로운 장르를 모색했다는 점에서는 아방가르드의 문학에 대한 사고를 보여준다. 그러나 이들의 비평은 역사 진보의 단일한 주체로 민중을 표상하면서 문학의 선전성을 강조하거나, 리얼리즘 장편 소설의 형식에 집착하는 가운데 자신들의 선구적 문제 의식을 스스로 소멸시켰다는 한계를 보여준다.
