이정우 ( Lee¸ Jungwoo ) 한국사회과교육학회 2021 시민교육연구 Vol.53 No.4

이 연구는 뉴스 리터러시 교육이 효과적으로 이루어지기 위한 사회과 교육과정의 개선 방향을 탐색하기 위하여 수행하였다. 이를 위해 뉴스 리터러시의 의미와 뉴스 리터러시 교육의 성격과 목표를 고찰하고, 이를 토대로 2015 개정 사회과 교육과정을 분석하여 그 특징을 파악하였다. 분석 결과는 다음과 같다: 첫째, 사회과 교육과정에서 ‘뉴스’는 성취기준에 직접 명시되기보다는 주로 교수·학습 방법과 관련하여 제시되고 있었으며, 대다수 진술문은 ‘뉴스 이용 교육’ 차원에서 뉴스를 학습 내용을 이해하기 위한 자료의 하나로 보고 이에 접근하는 데 초점을 두고 있었다. 이에 비해 ‘뉴스에 대한 교육’의 성격을 지니면서 뉴스를 이해하고, 비판적으로 분석하며, 뉴스를 생산하거나 활용하는 데 초점을 둔 진술문을 찾기는 어려웠다. 둘째, ‘뉴스에 대한 교육’으로 해석할 수 있는 진술문은 민주주의 정치과정에서 언론의 기능과 시민 참여, 뉴스에 대한 비판적 분석 등 뉴스 리터러시 교육의 핵심적 내용을 다루고 있었으나 모두 고등학교 선택 교육과정 문서에 제시되어 있었다. 셋째, ‘뉴스 이용 교육’과 관련된 진술문의 경우에도 교육의 방향이나 이를 토대로 한 구체적인 지침이 제시되어 있지는 않았다. 이러한 분석 결과를 토대로 2022 개정 사회과 교육과정을 통해 학습자들이 뉴스 리터러시를 효과적으로 함양하도록 하기 위해서는 뉴스 리터러시에 대한 균형적 접근, 공통 교육과정과 선택 교육과정 간 계열성 확보, 뉴스 이용 교육과 관련된 구체적 방안의 제시 등이 필요함을 제안하였다. This study was conducted to explore the direction of improvement of the social studies curriculum for effective news literacy education. To this end, the definition of news literacy and the nature and goals of news literacy education were considered, and the characteristics of the 2015 revised social studies curriculum were analyzed based on these criteria. The results are as follows: First, news was mainly presented in relation to teaching/learning methods rather than directly specified in the achievement standard, and most of the statements were made in terms of news-use education. Second, statements that can be interpreted as education on news dealt with the core contents of news literacy education, but all were presented in the high school elective subjects. Third, even in the case of a statement related to news-use education, the specific guidelines based on it were not presented. Based on the results of this analysis, the study suggested a balanced approach to news literacy, securing sequences, and specific guidelines related to news-use education.

Enhancement of Photocurrent Generation by C60-encapsulated Single-walled Carbon Nanotubes in Ru-sensitized Photoelectrochemical Cell

Jungwoo Lee,Taehee Park,Jongtaek Lee,Mira Jang,Seungjin Lee,Heesu Kim,한성환,이휘건 대한화학회 2012 Bulletin of the Korean Chemical Society Vol.33 No.8

Single-walled carbon nanotubes (SWNTs) and C60-encapsulated SWNTs (C60@SWNTs) are introduced to Rusensitized photoelectrochemical cells (PECs), and photocurrents are compared between two cells, i.e., an RuL2(NCS)2/DAPV/SWNTs/ITO cell and an RuL2(NCS)2/DAPV/C60@SWNTs/ITO cell. [L = 2,2'- bipyridine-4,4'-dicarboxylic acid, DAPV = di-(3-aminopropyl)-viologen, and ITO = indium-tin oxide] The photocurrents are increased by 70.6% in the presence of C60@SWNTs. To explain the photocurrent increase, the reverse-field emission method is used, i.e., RuL2(NCS)2/DAPV/SWNTs/ITO cell (or RuL2(NCS)2/DAPV/ C60@SWNTs/ITO cell) as an anode and a counter electrode Pt as a cathode in the external electric field. The improved field emission properties, i.e., β (field enhancement factor) and emission currents in the reverse-field emission with C60@SWNTs indicate the enhancement of the PEC electric field, which implies the improvement of the electron transfer rate along with the reduced charge recombination in the cell.

Backscattering measurement from a single microdroplet

Jungwoo Lee,Jin Ho Chang,Jong Seob Jeong,Changyang Lee,Shia-Yen Teh,Lee, A,Shung, K IEEE 2011 and Frequency Control Vol.58 No.4

<P>Backscattering measurements for acoustically trapped lipid droplets were undertaken by employing a P[VDF-TrFE] broadband transducer of f-number = 1, with a bandwidth of 112%. The wide bandwidth allowed the transmission of the 45 MHz trapping signal and the 15 MHz sensing signal using the same transducer. Tone bursts at 45 MHz were first transmitted by the transducer to hold a single droplet at the focus (or the center of the trap) and separate it from its neighboring droplets by translating the transducer perpendicularly to the beam axis. Subsequently, 15 MHz probing pulses were sent to the trapped droplet and the backscattered RF echo signal received by the same transducer. The measured beam width at 15 MHz was measured to be 120 μ m. The integrated backscatter (IB) coefficient of an individual droplet was determined within the 6-dB bandwidth of the transmit pulse by normalizing the power spectrum of the RF signal to the reference spectrum obtained from a flat reflector. The mean IB coefficient for droplets with a 64 μ m average diameter (denoted as cluster A) was -107 dB, whereas it was -93 dB for 90-μm droplets (cluster B). The standard deviation was 0.9 dB for each cluster. The experimental values were then compared with those computed with the T-matrix method and a good agreement was found: the difference was as small as 1 dB for both clusters. These results suggest that this approach might be useful as a means for measuring ultrasonic backscattering from a single microparticle, and illustrate the potential of acoustic sensing for cell sorting.</P>

이정우(Jungwoo Lee),이혜정(Hyejung Lee),이슬기(Seulki Lee) 한국IT서비스학회 2017 한국IT서비스학회지 Vol.16 No.3

IT project teams are composed of experts from various domains with different backgrounds, such as business and technologies. Thus, enhancing knowledge sharing and increasing team social capital are critical for the success of the project. This study examines the relationship among the team social capital, team climate and team performance. A research model and hypotheses are developed from literature review and empirically validated. The research model consists of team social capital, team climate and team performance. Specifically, team social capital, as antecedents, wasconceptualized asinternal and external differentiated by team boundary, and team climate is conceptualized as innovative climate and supportive climate. Using measures adopted from previous studies, 166 data points were collected to test the research model and related hypotheses. PLS data analysis indicated that internal and external social capitalhave positive effect on innovative climate while internal social capital has a positive effect on supportive team climate. The innovative and supportive climate has significant effect on the team performance. Based on the results, we proposed several team management skills for IT project managers. Theoretical constributions are discussed at the end with limitations and further studies.

Non-contact multi-particle annular patterning and manipulation with ultrasound microbeam

Lee, Changyang,Seob Jeong, Jong,Youn Hwang, Jae,Lee, Jungwoo,Kirk Shung, K. American Institute of Physics 2014 APPLIED PHYSICS LETTERS Vol.104 No.24

<P>Multiparticle-trapping offers diverse opportunities and applications in biotechnology. It can be applied to creating various functional materials or organizing reactive particles. In this paper, we demonstrate that it is possible to trap and manipulate multi-particles in an annular pattern with a 24?MHz focused ring-type single element ultrasound transducer. Acoustic ring trap can be useful in undertaking biotropism studies due to an equal-distance condition from the center. Also, this ring trap could serve as a force shield to protect analysis area from other cells. The experimental results showed the capability of the proposed method as a multi-cell manipulator in formatting specific patterns of small cells like sperms.</P>

Multiple genetically engineered humanized microenvironments in a single mouse

Jungwoo Lee,Dirk Heckl,Biju Parekkadan 한국생체재료학회 2016 생체재료학회지 Vol.20 No.3

Background: Immunodeficient mouse models that accept human cell and tissue grafts can contribute greater knowledge to human stem cell research. In this technical report, we used biomaterial implants seeded with genetically engineered stromal cells to create several unique microenvironments in a single mouse. The scope of study was focused on human CD34 hematopoietic stem/progenitor cell (HSPC) engraftment and differentiation within the engineered microenvironment. Results: A mouse model system was created using subdermal implant sites that overexpressed a specific human cytokines (Vascular Endothelial Growth Factor A (hVEGFa), Stromal Derived Factor 1 Alpha (hSDF1a), or Tumor Necrosis Factor Alpha (hTNFa)) by stromal cells in a three-dimensional biomaterial matrix. The systemic exposure of locally overexpressed cytokines was minimized by controlling the growth of stromal cells, which led to autonomous local, concentrated sites in a single mouse for study. This biomaterial implant approach allowed for the local analysis of each cytokine on hematopoietic stem cell recruitment, engraftment and differentiation in four different tissue microenvironments in the same host. The engineered factors were validated to have bioactive effects on human CD34+ hematopoietic progenitor cell differentiation. Conclusions: This model system can serve as a new platform for the study of multiple human proteins and their local effects on hematopoietic cell biology for in vivo validation studies.
