모빌리티 사회 내 탈(脫) 가정화 -크리스타 볼프의『메데아, 목소리들』을 중심으로

김연정 한국독어독문학교육학회 2023 獨語敎育 Vol.88 No.88

최근까지 메데아 연구는 독일통일을 기점으로 한 이념의 문제, 그리고 메데아를 악녀와 시대의 희생양 중 어느 그룹에 포함시키는가의 문제, 혹은 신화 속 인물과의 비교, 이방인의 문제, 여성성과 남성성, 젠더에 관한 주제가 대부분이었다. 가장 전통적인 주제인 메데아가 자식을 왜 살해했을까 에 대한 연구도 상당히 오래도록 진행되어 왔다. 이른바 메데아 콤플렉스 혹은 메데아 효과가 다 이 주제에서 나온 용어이다. 정신분석학적인 측면에서의 트라우마연구, 서술기법의 특징, 영웅주의와 연결시킨 현실비판의식의 고취 등 반복되는 연구도 이어졌다. 무대 공연에서도 에우리피데스의 메데아 를, 자식살해라는 키워드로 어미의 마음과 여자의 두 마음을 그려낸 <두 메데이아(2018 극단 서울공장)>가 공연되었다(김연정 2021, 339). 메데아가 악녀인지 희생양인지는 중요하지 않다. 본 논고에서는 시대의 흐름에 맞추어 메데아와 그 주변 인물들을 장소와 인물, 그리고 권력의 모빌리티 이론에 맞추어 새로운 시각으로 다가가고자 한다. Die griechische Mythologie liefert wichtigee Motive für die europäische Literatur Auf solch einem griechischen Mythos basiert Euripides Medea. Darin tötet Medea ihre Kinder, um sich an Jason zu rächen. Sie wird wegen Mordes an Kindern und Bruder als Teufel bezeichnet. Viele Jahre später wurde diese Sage von Christa Wolf in ihrem Roman Medea, Stimmen neu bearbeitet. Medea wird hier als Heldin wieder geboren. Durch die Verbindung von Medea und Glauke wird Medea eine Repräsentantin in Korinth, obwohl sie eine Ausländerin ist. In dieser Abhandlung wird der Mythos zu dem Drama, und in dem Roman verändert. Die Arbeit versucht, Medea hinsichtlich Mobilität zu interpretieren. Der Roman gliedert sich in elf Abschnitte. Und der wird aus der Sicht sechs verschiedene Personen erzählt. Die erzählerische Darbietungsform ist ein Monologe der Personen. Von diesen sechs Stimmen wird ein Bild von Medea neu gemacht. Die Welt bewegt sich. Medea bewegt sich auch in dieser Mobilitätsgesellschaft. Je nach Zeit wird Medea anders interpretiert. In dieser Abhandlung habe Ich Medea und andere Personen in der Theorie der Mobilität neu geforscht.

김연정,Jin, Zhanying,Tian, Lianhua,이민수 한국정보과학회 2014 데이타베이스 연구 Vol.30 No.1

The emergence of smart phones and the broad support for wireless connection has made socialnetwork service very popular and thus enabled the creation of large amounts of data. But the moredata we get, the more difficult it is to get the meaningful and requisite information for each person. Thus, it is necessary to have a highly accurate customized information recommendation systemwhich uses big data to reflect personal characteristics. In this paper, we proposed arecommendation algorithm that analyzes the friendship relations in social network services, theshared information and the evaluation information and assigns weights according to theirimportance. We also implemented a restaurant recommendation system using the proposedrecommendation algorithm as an Android-based smart software platform to determine theapplicability of our recommendation technique. 스마트폰의 등장, 무선인터넷 보급의 확대로 소셜 네트워크 서비스들이 폭발적인 인기를 얻게 되었고 사용자들은소셜네트워크 서비스를 통해 방대한 양의 데이터들을 만들어 낸다. 데이터가 많아질수록 그 안에서 자신에게 의미가 있고 필요한 정보를 얻는 것이 어렵다. 이에 빅 데이터를 이용하여 개개인의 특성을 반영한 정확도 높은 맞춤형정보추천 시스템이 필요하다. 본 논문에서는 소셜 네트워크 서비스에서 정보추천에 영향을 주는 친구관계, 공유정보, 평가정보들을 분석하고 그 중요도에 따라 가중치를 주는 추천 알고리즘을 제안하였다. 또한 안드로이드로 기반스마트 소프트웨어로 제안한 추천알고리즘이 적용될 수 있는 맛집 추천 시스템을 구현하여 추천알고리즘의 활용가능성을 확인하였다.

3T3-L1 세포에서 Resveratrol과 Epigallocatechin Gallate(EGCG)의 지방세포 분화 억제에 미치는 시너지 효과

김연정,곽호경,Kim, Yunjung,Kwak, Ho-Kyung 한국식품영양학회 2012 韓國食品營養學會誌 Vol.25 No.4

Resveratrol (RVT) and epigallocatechin gallate (EGCG) individually inhibit adipogenesis in 3T3-L1 adipocytes. The objective was to examine the possibility of interaction between RVT and EGCG, resulting in enhanced inhibition of adipogenesis in 3T3-L1 adipocytes. Preadipocytes were treated with RVT and EGCG individually at 6.25 or $25{\mu}M$ (RVT6.25 or RVT25) and 12.5 or $50{\mu}M$ (EGCG12.5 or EGCG50) and in combination (RVT6.25 + EGCG12.5 and RVT25 + EGCG50). RVT25 as an individual compound decreased lipid accumulation in 3T3-L1 adipocytes by 24%, and RVT25 + EGCG50 further decreased lipid accumulation by 77%. In addition, exposure of 3T3-L1 adipocytes to RVT6.25 + EGCG12.5 and RVT25 + EGCG50 combinations resulted in an enhanced increase of adiponectin release and inhibition of leptin release. Quantitative analysis revealed that the combination of tested materials (RVT6.25 + EGCG12.5 and RVT25 + EGCG50) decreased the expression levels of C/EBP${\alpha}$, PPAR${\gamma}2$, and aP2. These results indicate that the combined treatments with RVT and EGCG produce synergistic effects on inhibiting adipogenesis in 3T3-L1 adipocytes. The overall results suggested that the combining RVT and EGCG might be more capable of exerting antiobesity effects than each individual compound by itself.

청소년의 자발적 학교이탈에 관한 연구: 근거이론을 중심으로

김연정,주경필 한국청소년학회 2019 청소년학연구 Vol.26 No.8

The purpose of this study is to examine the process of adolescents' voluntary decision-making and execution and the life experiences afterwards using the grounded theory. Participants were 16 young people who run SNS related to youth human rights activists, and interviewed them in-depth and analyzed the data according to the procedure of the grounded theory. As a result, 'transformation from object to subject' was derived as the core phenomenon of adolescent voluntary school departure, and the causal and contextual conditions for this phenomenon were presented in detail. As a result, the study participants experienced 'turning point returning to me', 'anxiety and active cohabitation', and 'growing progress on the road I made'. Through this research, we developed a practical theory of what experiences adolescents who voluntarily choose to leave school experience in a complex context and discuss what social and policy support is needed in the future. 본 연구의 목적은 청소년이 자발적으로 학교이탈을 결심하고 실행하는 과정과 그 이후 삶의 경험을 근거이론 방법을 통해서 심층적으로 탐색ㆍ분석한 것이다. 연구참여자는 청소년인권활동가와 자퇴관련 SNS를 운영하는 중기청소년과 후기청소년 16명이고, 이들을 심층면접하여 근거이론 방법의 절차에 따라 자료분석을 실시하였다. 연구 결과, 청소년의 자발적 학교이탈의 중심현상으로 ‘객체(대상)에서 주체로의 변태’가 도출되었고, 이 현상에 대한 인과적 조건과 맥락적 조건을 구체적으로 제시하였다. 연구참여자들은 중심현상의 결과로 ‘나로 돌아오는 터닝 포인트’, ‘불안과 적극적 동거’, ‘내가 만든 길에서 성장 진행’을 경험하는 것으로 나타났다. 이 연구를 통해 자발적으로 학교이탈을 선택한 청소년이 복잡한 상황적 맥락 속에서 어떤 경험을 하는지에 관한 실체이론을 개발하였고, 향후 어떤 사회적ㆍ정책적 지원이 필요한 가에 대해서 논의하였다.

김연정,황해연,김윤회,류상훈,백승철,서을원 한국지반환경공학회 2007 한국지반환경공학회논문집 Vol.8 No.2

This study carried out to investigate the removal capacity of heavy metals such as Cu (II), Zn (II) and Cd (II) dissolved in aqueous solution in the soils collected from Hyeon-Dong (HD), San-seong (SS), Keum-chon (KC) and Keum-Hac (KH) located in the upper Banbyun stream. The pH of all the soils was weak alkali such as 8.8 9.2. According to the analysis of chemical composition of the soils, the amount of SiO2, AlO2 and CaO were similar in all tested soils. However, the amount of K2O, FeO3 and MgO were different from each soil. The XRD measurement with these soils showed that quartz and feldspar were presented in all tested soils, and the distribution of kaoline, illite, montmorillonite, vermiculite and calcite were different from each soil. The results of the removal capacity of heavy metals indicated that all the soils had more than 98% of the removal efficiency of Cu (II), Zn (II) and Cd (II), and among the heavy metals, Cu (II) was removed the most effectively. These results suggested that the soils collected from the upper Banbyun stream have the high removal capacity of heavy metals, and these soils could be used for the banking a river around the abandoned mine area, containing the higher concentrations of heavy metals than the usual stream. 본 연구는 반변천 상류에 위치한 현동, 산성, 금촌 그리고 금학 지역의 토양을 이용하여 물속에 존재하는 Cu(II), Zn(II) 및 Cd(II)과 같은 중금속 이온의 제거능을 조사하였다. 조사 지역에서 채취한 토양의 pH는 8.8~9.2로서 약알칼리성을 나타냈으며, 토양의 화학적 구성 성분 중 SiO2, Al2O3 및 K2O는 양적으로 비슷한 분포를 보였으나, Na2O, TiO2 Fe2O3 CaO 및 MgO는 토양마다 약간의 차이를 나타냈다. 이 지역의 토양을 XRD로 측정 결과, 석영과 장석은 공통된 광물질로 확인되었으나, 카올린, 일라이트, 몬모릴로나이트, 버뮤큘라이트 및 칼사이트는 토양에 따라 다소의 정성적 차이를 나타냈다. 또한 이들 지역의 토양을 사용하여 중금속 제거 실험을 한 결과 Cu(II), Zn(II) 및 Cd(II)의 제거 효율은 98% 이상으로 나타났으며, 특히 다른 중금속에 비하여 Cu(II)의 제거율이 가장 높게 나타났다. 이러한 결과로 보아 본 조사지역의 토양을 폐광과 같은 중금속 상시 유출 지역의 제방 및 복토재로 활용할 경우 폐광 유출수내 중금속을 보다 효율적으로 제거할 수 있을 것으로 사료된다.

김연정,권세웅,윤완석,김정일,윤영중 한국전자파학회 2000 한국전자파학회논문지 Vol.11 No.3

본 논문에서는 단일 안테나를 가지고 광대역의 위성통신 신호를 송수신하기 위하여 12.5 GHz와 14.25 GHz 대 역에서 각각 동작하고, 두 대역에서 서로 다른 선형편파 특성과 광대역 특성을 얻을 수 있는 적층 구조의 광대역 이중공진 이중편파 안테나를 제안하였다. 이 때 상대 급전선에 의한 임피던스 변화를 최소화시켜 최적의 안테나 를 설계하였으며, 배열 안테나로 확장시 이중급전 구조의 문제점인 공간상의 문제를 해결하기 위해서 마이크로 스트립 선로와 via-hole 혼합급전 방식을 사용하였다. 제안된 안테나를 광대역 이중공진 이중편파 $2\times2$ 배열 안 테나로 설계 및 제작하였고, 방사패턴과 주파수특성을 측정하여 위성통신 송수신 겸용 광대역 안테나로 잘 동작 할 수 있음을 확인하였다. In this paper, to transmit and receive the differently polarized wideband signals simultaneously with a single antenna system, the wideband, dual-frequency and dual-polarized(WDFDP) microstrip array antenna is proposed and designed. This antenna operates simultaneously at 14.25 GHz and 12.50 GHz. To extend to two dimensional array, microstrip feed line and coaxial probe through via-hole are used. The experimental results show that the proposed WDFDP microstrip antenna can be used in the compact portable terminals with a single antenna system and the characteristic of the resonators in this antenna produces a greatly enhanced bandwidth.

분만계절이 TMR 급여 홀스타인 육성우의 분만 후유생산과 비유지속성에 미치는 영향

Total of 20 Holstein calves of 10 calves (3.90±0.26 month of age) born in spring (S) and 10 calves (4.10±0.30 month of age) born in fall (F) were reared in this study for 24 months and diets were divided into separate feeding of forage and concentrates (C) and TMR (T). Therefore, 4 treatments in this study were composed of CS, CF, TS and TF with the factors of diets and calving season. After parturition of heifers, all animals were fed the same diet and milk production was recorded monthly. DM intakes in growing period were influenced by calving season, and those of the animals calved in fall were higher than in those calved in spring (P<0.01), but there were no significant differences by feeding method. CP intakes and TDN intakes were significantly influenced by calving season (P<0.05) and feeding method (P<0.001), and the animals calved in fall were about 1.2% higher than those calved in spring, and the animals fed TMR were about 4.7% higher than those fed concentrates and forage separately. Average, 9th and 10th months' milk yields were significantly influenced by feeding method in which those in the treatments fed TMR (TS, TF) were higher than in separate feeding of concentrates and forage (CS, CF; average P<0.05; 9th and 10th months P<0.01). Average milk persistency was also significantly influenced by calving season (P<0.05) and feeding method (P<0.01) and those in the animals calved in fall were higher than in spring and those of the TMR fed animals were also higher than in separate feeding of concentrates and forage. Milk persistency was similar to the results of milk yield, showing statistically significant differences affected by the feeding method at 9th and 10th months of late lactation (P<0.01), and it was about 8% higher in the animals fed TMR, showing higher tendency at 7th (P=0.12) and 8th months of late lactation (P=0.09). Therefore, it is expected that postpartum milk yield and milk persistency would be higher when the hiefers are fed TMR in growing period and calved in fall. Average milk fat content was influenced by feeding method. Milk fat content of the animals fed TMR during growing period were 7.8% higher than those fed concentrates and forage separately (P<0.01). This suggests that feeding TMR during growing period influenced first postpartum eating behavior, which stabilized the rumen and resulted in the increased milk fat. At 3rd month after calving, milk fat content was lower in the animals calved in spring than in those calved in fall, suggesting that it might have been influenced by the seasonal differences. MUN showed significant differences by feeding method in which those in separate feeding of concentrates and forages were higher especially in average, 4th, 5th and 6th months (average and 4th P<0.01; 5th and 6th months P<0.05). SCC was higher in the animals fed TMR than in those fed concentrates and forage separately especially in average, 3rd and 4th months after calving (P<0.01). In conclusion, when feeding TMR during growing period and calving in fall, it was not influenced by the high temperature in summer, and it resulted in the improved milk yield, milk persistency and milk fat content.

Identification of estrogenic genes responding to phthalate esters treatment in human MCF-7 cells

김연정,Eun-young Kim,류재천 대한독성 유전단백체 학회 2011 Molecular & cellular toxicology Vol.7 No.2

The phthalate esters represent a class of chemicals used widely and diversely in industries as a plasticizer for elasticity and adhesion. Some phthalate diesters are classified as endocrine disrupting chemicals (EDCs), because they have been found weakly estrogenic. This study aimed to identify the changes of gene expression profiles by BBP, DBP,and DEHP using cDNA microarray. Firstly, we have selected the MCF-7 cell line, mainly used to estrogenic related research and selected the doses appearing the highest estrogenicity in E-screen assay to examine the estrogenicity and gene expression profiles of phthalate esters. Total RNA was isolated from cells treated with each phthalate esters (BBP, DBP, and DEHP) and 17β-estradiol, and then changes of gene expression were analyzed using cDNA microarray (KISTCHIP-400). This microarray includes 416 endocrine related genes based on public database and research papers. For the microarray analysis, genes that showed a 1.5-fold or greater change in their expression level (increase or decrease) were detected as differentially expressed genes (DEGs). Of the 416 genes analyzed, 95, 26, and 63 genes were identified showing significant changes in gene expression resulting from BBP, DBP, and DEHP, respectively. Among these genes, 11 genes,including MGP, SEPP1, and BAK1 were induced by more than 2 of 3 phthalate esters compared with 17β-estradiol. Therefore, it suggests that these genes may be associated with estrogenic effect of the phthalate esters on transcriptional level.
