2000년대 이후 한국시의 도시 표상 연구 - 이기인·조동범·서대경 시를 중심으로

이혜원(Lee, Hyewon) 문학과환경학회 2021 문학과 환경 Vol.20 No.4

이 논문에서는 환경인문학의 관점에서 2000년대 한국시에 나타나는 도시 표상을 살펴보았다. 이기인, 조동범, 서대경의 시를 중심으로 이들의 시에 나타나는 공간의식과 이미지의 발현 양상에 주목하여, 1990년대 ‘도시시’와 달라진 새로운 문제의식과 미의식을 규명했다. 이기인의 시에서 도시는 신자유주의로 인해 더욱 불평등해진 사회구조를 반영하는 차별적 공간이다. 그는 도시의 차별적 인간관계를 드러내는 상징적 이미지들을 통해 계급적 격차가 심화되어가는 자본주의적 삶의 위기를 포착한다. 조동범의 시에서 도시는 차갑게 반짝이는 매장과 쾌속으로 질주하는 ‘속도’로 가득한 공간이다. 그의 예리한 시선으로 재현되는 투시적 이미지들은 현대도시에 내재하는 빛과 어둠, 풍요와 고립, 질주와 정지의 불길한 교차점을 포착해낸다. 서대경 시에서 도시는 꿈속에서조차 벗어날 수 없는 절대적인 삶의 공간이다. 서대경은 환상적 투시를 통해 인간 소외가 심화된 현대도시의 속성을 내밀하게 묘파한다. 이들의 시에 나타나는 도시에서는 공통적으로 ‘무장소성’이 두드러진다. 도시는 모두에게 절대적인 공간이 되었지만, 개별 도시의 특성이 사라져 독자적인 정체성을 찾아보기 힘든 장소가 되었다. 세 시인 모두 압도적인 도시 공간에서 소외된 인간 존재에 주목한다는 점에서도 공통점을 보여준다. 2000년대 한국시의 도시 표상은 성장 위주의 개발과정에서 도달한 화려한 도시의 그늘에 도사린 심각한 인간 소외의 양상을 통해 도시의 지속가능성을 위한 중요한 과제를 제시한다. From the perspective of environmental humanities, this paper examines the urban representations in Korean poetry since the 2000s. In this paper, I studied the new problem consciousness and aesthetics that have changed from the previous period through the expression of spatial consciousness and images implied by urban representations in poems of Lee Ki-in, Cho Dong-beom, and Seo Dae-kyung. Lee’s poems describe the social structure that has become more unequal due to neoliberalism as a discriminatory space. Lee captures a capitalist life crisis in which the class gap widens through symbolic images that reveal the discriminatory human relationships of the city. Cho sharply captures the shadow of death, which is implicit in the consumption of urban space. He puts the solitude and danger of a highly civilized and capitalist city in an apocalyptic landscape. In Seo’s poems, the city is an absolute place of life that cannot be escaped even in dreams. Fantasy in his poems strengthens the reality, because he grasps the attributes of modern cities where human alienation has intensified through fantastic speculation. The cities that appear in their poems show generally ‘placelessness.’ Cities have become absolute spaces for everyone, but the characteristics of individual cities have disappeared, making it difficult to find their own identity. All three poets also show something in common in that they pay attention to the existence of humans alienated from the overwhelming urban space. The urban representations in Korean poetry in the 2000s present an important task for the sustainability of the city through serious human alienation lurking in the shadow of a spectacular city reached in the process of growth-oriented development.

이혜원,임희빈,이귀복,박소연,전정인,이철민,Lee, Hye-Won,Lim, Hui Been,Lee, Kwi-Bok,Park, So Yeon,Jeon, Jeong In,Lee, Cheol Min 한국환경과학회 2020 한국환경과학회지 Vol.29 No.6

This study investigates the concentration distribution of aldehydes and volatile organic compounds (VOCs) in the archive of the National Library in Korea and evaluates the health risks to workers from hazardous chemicals. Acetaldehyde had the highest concentration among the nine species of aldehydes present in the archive and the concentration of toluene was the highest among the six species of VOCs. Most of the detected substances showed that their indoor concentrations were higher than the outdoor ones, suggesting the possibility of indoor sources of aldehydes and VOCs. The evaluation of health risks for workers based on these measurement results showed that not all substances were hazardous to the human body. However, considering the possibility of the presence of indoor sources and the potential limits of our study owing its short period, it is necessary to conduct long-term studies on the concentration distribution of indoor pollutants in the archive environment.

This study was attempted to provide us with basic information on how to improve understanding with patients for operation, and to offer then better nursing and treatment. This kind of study will help scientific application to nursing practice and operating room. The data was collected by interviewing 29 patients who underwent the elective surgery under the general anesthesia at Y hospital in Seoul. The interview ran from October 15 to December 15, 1989. The research instrument was a anxiety measurement device (SAAI) originally developed by Spielberger, et al and modified by Jung-Tack Kim. 1. Hypothesis Testing Hypothesis one was that there would be a difference in state anxiety level according to a time difference in watiting for operation. This hypothesis was rejected(state.anxiety level one hour before operation P>.05, r-.747, State anxiety level half an hour before operation P>.05, r-.1550, state anxiety level just before operation, P>.05, r=.1099). However, state anxiety, evel appeared to be associated with a longer watiting period, like one day before operation (P<.05, r-.4628). Hypothesis two was that there would be a difference according to state anxiety level of patients for operation. This was rejected. (Change of blood perssure in systolie P>.05 r=.1082, Change of blood pressure in diastolic P>.05, r=.088, Change of pulse rate, P>.05, r-1.909) 2. Examining trait anxiety and state anxiety levels, the average level of trait anxiety was 42.034, and the average level of state anxiety one day before operation was 43,000. The average level of state anxiety was averaged 42.356 in a waiting room for operation. 3. Examining the state anxiety level by time period, the one hour before was 42.379 the level half an hour before 42.276, and the level just before operation 42.414. The low level of state anxiety was due to the fact that premedication was not eliminated. 4. Age and time period like one day before operation was related to state anxiety level (F=5.271, P<.0.01) and blood pressure in waiting room for operation. That is, state anxiety level and blood pressure of patients one day before operation appeared high. Sex was relation to changes of blood pressure ; the blood pressure of male patients appeard higer than of female patients. A marital status was also related anxiety level one hour before operation the married patient for operation showed a higher state anxiety level than that of the unmarried patient for operation. Education was similarily related to trait anxiety level in which highly educated patients show lower levels of trait anxiety than poorly educated ones. Motive for hospitalization was related to state anxiety level for patient one hour before operation (F=6.464, P<.05) likewise, patients who are supposed to undergo operation hastily showed higher levels of anxiety than patients who expect elective surgeries.

Background: This study aimed to obtain the symptom, prescription and therapeutic patterns for the treatment of patients with menopausal syndrome in major Korean medicine (KM) hospitals. Methods: We used a retrospective chart review of climacteric disorder and postmenopausal syndrome patients by examining medical records (ICD-10, menopausal and female climacteric states: N95.1, Menopausal and perimenopausal disorder, unspecified: N95.9) from eight university KM hospitals in South Korea. Results: The main symptoms of 1,682 patients with menopausal disorders visiting eight college-affiliated oriental medicine hospitals were hot flush, hyperhidrosis, fatigue, insomnia, and chest tightness. Guipi decoction, Si-wu guipi decoction, Qing-xin lianzi-yin, Jiawei xiao-yao-san and Guipi wen-dan decoction were the most commonly prescribed treatments for menopausal disorders. Patients were most often treated with a combination of herbal medicine and acupuncture. Conclusion: Our study shows that the current prescribed herbal medicines were used for treating menopausal disorders in Korean medicine hospitals. However, the objectivity of the efficacy assessment should be studied further

교사 행위자성(teacher agency)에 기반한 가정과교사의 포괄적 성교육 실천 탐구

이혜원,박미정,Lee, Hyewon,Park, Mi Jeong 대한가정학회 2022 Human Ecology Research(HER) Vol.60 No.3

Based on an ecological model of teacher agency, the purpose of this study was to examine the relevance of HE (home economics) subjects and CSE (comprehensive sexuality education) for HE teachers, and their implementation in HE classes. To achieve this, a survey was conducted with HE teachers nationwide for which 243 responses were collected, and interviews were conducted with five HE teachers who were actively practicing CSE. The results of the survey and interview were as follows. First, HE teachers strongly recognized the relevance of HE subjects and the topic of CSE with an average score of 4.63 (out of 5 points), and practiced CSE at an average of 72.23% (97.12%~43.21%) in their class. Second, based on the ecological approach model of teacher agency, the factors facilitating the CSE practice of HE teachers included: childbirth and parenting experienced as parents, experiences of students encountering sexual problems in school, the philosophy and content of HE subjects, positive feedback from students and support from fellow teachers, and intention to help students in their lives. Conversely, HE teachers cited a lack of sexual education experience as learners, complaints from parents, weakness of HE teacher networks, lack of specific statements in curriculum and textbooks, insufficient class content and teacher training, and lack of absolute class time. This study is significant in revealing that CSE is highly relevant to the contents of HE subjects and is already being practiced in HE classes.

이혜원,Lee, Hye-Won 한국도서관정보학회 2008 한국도서관정보학회지 Vol.39 No.2

본 연구에서는 정보활용능력을 향상시키기 위해 학교도서관의 사서교사와 일반 교과의 교사들 간의 협력 방안을 제시하고자 하였다. 또한 교육의 또 다른 주체인 학생을 중심으로 한 부분을 확대함으로써 좀 더 효율적인 교수-학습이 이루어질 수 있도록 하였다. 무엇보다 교사와 학생들의 커뮤니케이션에서 직접적인 교환이 이루어지는 지식을 중심으로 주제, 교육학적인 배경, 정보기술의 활용 등을 고려한 모형을 제안하였다. In this study, collaboration of teacher librarians and subject teachers in school libraries has been investigated(tried, attempted, suggested) in order to improve the information literacy. The effective teaching-learning can be conducted by extending student's roles, which are essential elements in school education. Above all, the model. focused on direct exchange of knowledges in communications between teachers and students has been suggested with consideration of content knowledge, pedagogical knowledge, and technological knowledge.

리튬이차전지 출력측정법의 원리 및 측정법간 비교 연구

이혜원,이용민,Lee, Hye-Won,Lee, Yong-Min 한국전기화학회 2012 한국전기화학회지 Vol.15 No.3

리튬이차전지의 수요가 소형 휴대용 전자기기에서 중대형 전기자동차와 에너지저장장치로 변화함에 따라, 요구되는 전지 특성도 크게 달라지고 있다. 10년 이상의 장기 신뢰성, 팩 수준의 안전성, 가격 경쟁력 확보 등 기존 소형 전지보다 크게 강화된 요구 조건뿐만 아니라, 고출력 특성도 함께 필요로 한다. 그런데, 출력을 측정하기 위해서는 전압과 전류가 동시에 측정 및 제어되어야 하기 때문에, 기존의 단위셀 용량 측정보다 훨씬 어렵다. 또한, 측정 방법의 선택뿐만 아니라 출력유지시간, 충전상태(State-of-Charge, SOC), Cut-off 조건, 측정온도 등의 측정 조건에 따라서도 그 측정값이 크게 달라지는 경향이 있다. 본 논문에서는 HPPC (Hybrid Pulse Power Characterization)법, J-pulse(Japan Electric Vehicle Association Standards, JEVS D 713)법, 정출력 측정법(Constant Power Measurement)의 측정 원리 및 실제 실험에 어떻게 적용해야 하는지 설명하고, HEV(Hybrid Electric Vehicle)용 단위셀을 이용해 출력법간 측정 결과를 비교 분석한다. As the market of lithium secondary batteries moves from mobile IT devices to large-format electric vehicles or energy storage systems, the strengthened battery specifications such as long-term reliability longer than 10 years, pack-level safety and tough competitive price have been required. Moreover, even though high power properties should also be achieved for hybrid electric vehicles, it is not easy to measure accurate power values at various conditions. Because it is difficult to choose a proper measurement method and its experimental condition is more complex comparing to capacity measurement. In addition, the power values are very sensitive to power duration time, state-of-charge (SOC) of cells, cut-off voltages, and temperatures, whereas capacity values are not. In this paper, we introduce three kinds of power measurement methods, hybrid pulse power characterization (HPPC) suggested by US FreedomCar, so-called J-pulse by Japan electric vehicle association standards (JEVS) and constant power measurement, respectively. Moreover, with pouch-type unit cells for HEV, experimental power data are discussed in order to compare each power measurement.

Biologic Response of Human Deciduous Dental Pulp Cells on Newly Developed MTA-like Materials

이혜원,신유석,정재은,김성오,이제호,송제선,Lee, Haewon,Shin, Yooseok,Jung, Jaeeun,Kim, Seongoh,Lee, Jaeho,Song, Jeseon Korean Academy of Pediatric Dentistry 2015 大韓小兒齒科學會誌 Vol.42 No.4

본 연구의 목적은 다양한 MTA 재료(ProRoot MTA, RetroMTA, Endocem Zr)에 대한 유치 치수 세포의 생활력 및 분화능을 비교 평가하는 것이다. 유치 치수세포는 각 재료별로 경화된 원형 디스크를 이용하여 직접법 및 간접법으로 세포 생활력을 관찰하였다. 또한 재료별 추출물을 이용하여 pH를 측정하였으며, alkaline phosphatase(ALP) 활성도 및 Alizarin Red S 염색법을 통하여 세포의 분화능을 관찰하였다. 직접법에서 유치 치수세포는 ProRoot MTA와 RetroMTA에서 Endocem Zr에 비해 높은 세포 생활력을 보였으나, 반면 간접법에서는 Endocem Zr에서 다른 재료에 비해 높은 세포 생활력이 관찰되었다. pH의 경우 Endocem Zr가 다른 두 재료에 비해 낮은 알칼리성을 나타냈다. 모든 재료에서 ALP 활성도는 대조군에 비해 증가하지 않았으며, Alizarin Red S 염색결과 유치 치수세포의 분화능이 대조군에 비해 낮았다. 본 실험에서 재료별 차이는 있었으나 모든 재료에서 어느 정도의 세포 독성이 관찰되었으며, 유치 치수세포의 생활력과 분화능을 증진시키지 못하였다. 하지만 Endocem Zr의 경우 ProRoot MTA나 RetroMTA에 비해 낮은 알칼리성과 높은 생활력을 보였다. This study compared the in vitro cell viability and differentiation potentials of human deciduous dental pulp cells (DPCs) on mineral trioxide aggregate (MTA)-like products (ProRoot MTA, RetroMTA and Endocem Zr). The experimental materials were prepared as circular discs, which were used to test the effects of the materials on the viability of human DPCs when placed in direct and indirect contact. Furthermore, the pH of the extracted materials was recorded, and their effect on cell differentiation potential was evaluated by evaluating the alkaline phosphatase (ALP) activity and Alizarin Red S staining of DPCs incubated with the test materials. In direct contact, the cell viability of human DPCs was higher with ProRoot MTA and RetroMTA than with Endocem Zr. However, when in indirect contact, the cell viability of human DPCs was generally higher in Endocem Zr than in ProRoot MTA and Retro MTA. With respect to pH, the alkalinity was lower for Endocem Zr than for the other test materials. The ALP activities of the cells were not enhanced by any of the experimental materials. Alizarin Red S staining of the tested human DPCs revealed that their differentiation potential was lower than for cells incubated with osteogenic induction medium. While there were differences in the responses of the human DPCs to the test materials, all displayed degrees of cytotoxicity and were unable to enhance either the viability or differentiation of human DPCs. However, Endocem Zr exhibited better cell viability and was less alkaline than the other test materials.

자율주행 자동차의 제어권 전환 시간 확보를 위한 차간 통신 기반 종방향 제어 알고리즘 개발

이혜원,송태준,윤영민,오광석,이경수,Lee, Hyewon,Song, Taejun,Yoon, Youngmin,Oh, Kwangseok,Yi, Kyongsu 한국자동차안전학회 2020 자동차안전학회지 Vol.12 No.1

This paper presents a longitudinal control algorithm for ensuring takeover time of autonomous vehicle using V2V communication. In the autonomous driving of more than level 3, autonomous systems should control the vehicles by itself partially. However if the driver's intervention is required for functional safety, the driver should take over the control reasonably. Autonomous driving system has to be designed so that drivers can take over the control from autonomous vehicle reasonably for driving safety. In this study, control algorithm considering takeover time has been developed based on computation method of takeover time. Takeover time is analysed by conditions of longitudinal velocity of preceding vehicle in time-velocity plane. In addition, desired clearance is derived based on takeover time. The performance evaluation of the proposed algorithm in this study was conducted using 3D vehicle model with actual driving data in Matlab/Simulink environment. The results of the performance evaluation show that the longitudinal control algorithm can control while securing takeover time reasonably.
