Ordinary People"s Tragedy : Comparative Study of Plays of Arthur Miller and Beomsuk Cha

Yonghee Lee 한국영어어문교육학회 2007 영어어문교육 Vol.13 No.1

  The main concern of the study is the playwrights’ perspectives toward the relationship between society and individuals rather than specific cultural or social circumstances. This study is justified in that the similarities of both playwrights not only provide an opportunity to bridge two different cultures, but they also help readers understand another culture and deepen the understanding of their own culture in the map of international literature. In their plays, both Miller and Cha express an individual’s or a family’s frustration, conflict, pleasure, and hope as reflected in the social circumstances. The characters take ideas and values from their social world and thrive or fail. Specifically, I have focused on three elements--obsession, generational value systems, and alienation. With three common features, I examine how closely Miller and Cha deal with ordinary people’s tragedies.

Standard protocol conversion of digital ECG for healthcare

Yonghee Lee,Sinhyuk Kang,Kangwoo Lee 한국정보기술학회 2017 Proceedings of The International Workshop on Futur Vol.2017 No.5

In this paper, we present a method for converting the digital SCPECG used in clinical practice to the MFER standard for use in health care. Since the SCP-ECG has a complex representation format for each section, we simplify the structure by separating only the items necessary for healthcare use. We convert the structure of each section of SCP-ECG to TLV format, such as tag, length, and value. The converted result is expressed in MFER format using different tags according to the expression contents. The results show that we can simplify the structure of the SCP-ECG and translate it into other standard formats, so that it can be used in the health care field.

The most accurate results on soil amplification can be obtained from full-scale model. However, it is often impractical because of the cost of full scale model and the natural uncertainty of earthquake occurrence. Therefore, lab-scale physical modeling such as 1-g shaking table and centrifuge tests are widely performed to determine the effect of ground motion during earthquake. Meanwhile, the boundary effect is one of the major limitation in lab-scale physical model. In this study, laminar shear box (LSB) to minimize the boundary effect was developed, and the capacity of developed LSB was evaluated using preliminary 1-g shaking table test. LSB is composed of a stack of aluminum frames. Ball bearings between the aluminum frames allow the lateral displacement of the box corresponding soil deformation during the dynamic loading time. The height, length, and width of LSB are 2,000, 600 and 600 mm, respectively. Sine sweep test (from 2 Hz to 30 Hz) was conducted to determine the response characteristic of LSB. Furthermore, numerical modeling was performed using the DEEPSOIL version 7.1, and FLAC 2D software. LSB shaking table test results on center and boundary area of LSB are well matched with the numerical analyses results. However, response of boundary area is slightly larger than that of center area. It seems that this phenomenon is induced by the inevitable partial reflection of the seismic wave at the boundary. The test results show that LSB greatly mitigate the boundary effect of the lab-scale physical modeling in comparison to conventional rigid box (RB).

New Approach for Slope Deformation Measurement Using Terrestrial LiDAR in Nuclear Power Plant Site

( Yonghee Lee ),( Weon-hack Choi ),( Hak-sung Kim ),( Seok-chul Kim ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

Recently, slope failures are frequently occurred in Korea due to localized torrential rainfalls induced by the world climate change. Therefore, the stability of slopes in nuclear power plant sites has become a major geotechnical issue in the nuclear industry. The slope monitoring using slope-mounted sensors (e.g., inclinometer, tension-wire, and precipitation gauge) are the most accurate and reliable motioning method for slopes. However, slope-mounted sensor systems are ineffective to evaluate the overall deformation of large slopes because measured data from the each slope-mounted sensor represent the single cross-area of the slope. In this study, terrestrial light detection and ranging system (LiDAR) was used to evaluate the overall slope deformation without slope-mounted sensor system. The testbed slope is located in ○○ nuclear power plant site. The length, height, and slope angle of the slope is 1,700 m, 80 m and 34°, respectively. The measurement and analysis procedure are as follows: (1) point cloud data acquisition using terrestrial LiDAR, (2) station adjustment using global navigation satellite system (GNSS), (3) noise filtering to remove unnecessary data (e.g., trees and transmission towers), and (4) slope digital elevation model (DEM) generation. The terrestrial LiDAR data that obtained in 2015 (53 scan positions) and in 2016 (91 scan positions) were compared in this study. There was no significant deformation on the testbed slope, however, slight sediment-scouring which has no impact on the slope stability was observed. Deformation analysis using terrestrial LiDAR data obtained periodically is cost-effective and reliable to monitor the overall deformation of the large slopes.

Highly luminescent blue-emitting CdZnS/ZnS nanorods having electric-field-induced fluorescence switching properties

Lee, Yonghee,Kim, Somang,Kim, Hyo Seok,Shin, Jeong Bin,Choi, Wonseok,Cho, Hyunjin,Kim, Kyungmok,Lee, Taeyang,Kim, Jinwuk,Kang, In-Byeong,Choi, Kyung Cheol,Kim, Yong-Hoon,Jeon, Duk Young The Royal Society of Chemistry 2017 Journal of materials chemistry. C, Materials for o Vol.5 No.8

<P>We demonstrate for the first time highly luminescent blue-emitting CdZnS/ZnS wurtzite core/shell nanorods (NRs) that show electric-field-induced fluorescence switching properties. Uniform CdZnS NRs were rapidly synthesized by injecting sulfur powder dissolved in 1-octadecene into a flask containing phosphonic acid ligands, and subsequently ZnS shells were coated using reagents consisting of sulfur powder, zinc sulfate heptahydrate, and oleylamine. The growth of high-quality ZnS shells resulted in a dramatically increased photoluminescence (PL) quantum yield (QY) of ∼40% with a minimal red-shift of the blue PL peak, which indicates that the combination of reagents successfully controlled a large number of defects appearing on the surface of the NR cores. By pre-annealing CdZnS cores before growing ZnS shells, we could achieve an additional increase in the maximum PL QY to 50%, decreases in both the full width at half maximum (FWHM) and the red-shift of the PL peak, and improved electric-field-induced fluorescence switching performance. Density functional theory calculations reveal that the effective relaxation of strain accumulating on the NR core during shell growth is the key to our successful synthesis of blue-emitting NRs, and that the additional improvement in performance obtained through the pre-annealing process results from the elimination of sulfur vacancies appearing at the surface of the NR core.</P>

본 연구는 우리나라 최초의 유치원인 이화여자대학교 사범대학 부속 이화유치원의 교육과정을 구성하고 있는 이론적 근거를 역사적ㆍ철학적으로 고찰하는 것을 그 목적으로 하였다. 본 연구는 문헌연구를 통하여 이화유치원 설립 당시부터 현재까지의 교육과정의 성립 및 변천과정과 철학적ㆍ심리적 사조를 살표보고 이들의 영향이 이화유치원 교육과정에 나타난 부분을 탐구하였다. 연구결과 1914년 한 미국인 선교사에 의해 설립된 이화여자대학교 사범대학 부속 이화유치원은 설립 이후 지금까지 우리나라 유치원 교육의 모델을 제시하며 선도적 역할을 담당해오고 있음을 알 수 있었다. 교육과정의 측면에서는 유아들의 전인발달 특히 사회ㆍ정서적인 발달을 중요시하고 우리의 전통사상과 기독교정신, 진보주의 이론 및 구성주의가 그 철학적ㆍ심리적 기초를 이루고 있음을 알 수 있었다. The purpose of this study was to investigate historical, philosophical, and psychological foundations of the curriculum for Ewha Lab Kindergarten. This study was conducted through mainly literature review and interview. The results of this study are as follows. First, the Ewha Lab Kindergarten, which was founded in 1914, is the very first kindergarten for Korean children. It has played the leader's role of the field of early childhood education in Korea since then. Second, the curriculum of Ewha Lab Kindergarten was differentiated from other kindergartens' from its beginning in the sense that it was based on the firm belief of child-oriented philosophy. Third, essence of the curriculum for Ewha Lab Kindergarten has remained the same despite of its several changes. It has put emphasis on the development of the whole child, especially social-emotional development, and child-oriented curriculum which is based on the child's interests and experiences. Fourth, the curriculum for Ewha Lab Kindergarten was influened by several philosophies and psychological theories. Among those, Korean traditional thoughts, Christianity, Progressivism, and Constructivism are the most salient. Because Ewha Lab Kindergarten was founded by American missionary, Christianity was the basis for the curriculum. Examples can be that hymns, prayer, and bible stories are included in the curriculum and Easter, Thanksgiving, and Christmas are also celebrated. Perspectives on the purpose of education, development of young children, and the teacher's role were influenced by Korean traditional thoughts. The contents, teaching strategies, the teacher's role, and educational environments were heavily influenced by both Progressivism and Constructivism.

Applicability Evaluation of Fault Characteristic Analysis using Terrestrial LiDAR

( Yonghee Lee ),( Weon-hack Choi ),( Hak-sung Kim ),( Seok-chul Kim ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

It is common that the geometric information of faults is obtained directly by field investigation. However, there are several limitations to obtain the quantitative geometric information from the field investigation when investigator is difficult to access. When the fault is located on the steep slope, fault displacements have been measured with naked eye or indirectly method. The indirect measurement can lead the intervention of subjectivity which can cause a large range of epistemic uncertainty. Recently, the terrestrial LiDAR (light detection and ranging) technique has been introduced in the geological investigation to obtain quantitative geometric information of geological structures including faults. Since LiDAR technique provides full three-dimension (3-D) model of geological outcrop, fault geometric information can be measured accurately. LiDAR uses pulsed laser light to measure distance to the target and relative coordinates of the targets are calculated from flight time or phase difference of reflected laser pulses from targets. A 3-D model of the terrain feature can be obtained using position information data (i.e., point clouds) of reflection points. In this study, the applicability of terrestrial LiDAR technique for fault characteristic analysis was evaluated based on the field-test results. The study area is located in the road construction site near Hwa-gok reservoir in Kyoung-ju, south-eastern part of Korea. 3-D outcrop point clouds including fault were built using the terrestrial LiDAR device. Color mapping, reflectance, and echo amplitude of obtained point cloud data were analyzed. Analyses results show that the terrestrial LiDAR technique is effective for geologic structures.
