본 연구는 교육인류학도 세 명의 교육 생애를 협력적으로 탐구한 자문화기술지이다. 연구자-참여자들은 대학원 진학 전후 교육현장에서 마주한 서로의 성장 경험을 교차적으로 검토했다. 공통적으로, 우리는 중등교육 시절 학교 안팎에서 불평등을 경험하고 이에 대한 지적 호기심을 마주했다. 이에 더해, 당시 각자가 형성한 이상적인 인간상의 모습은 우리가 대학원에 진학하기로 결심하는 주요한 계기가 되었다. 대학원 진학 후, 우리는 입학 전 가진 불평등과 관련된 문제의식을 다양한 방식으로 탐구했다. 이러한 학습 경험은 지적 희열이나 내적 성장으로 이어지기도 했다. 그러나 우리는 전일제 대학원생으로서 학생과 직업 사이에 위치한 애매한 존재로 정의되며 갈등을 겪기도 했고, 이러한 고민의 과정은 대학원 졸업 후의 진로를 구상하는 데에 영향을 미쳤다. 우리의 작업은 기초학문의 성격을 가진 전공공동체에 속한 전일제 대학원생의 교육 경험을 심도 있게 탐색하며, 특히 학문후속세대가 처한 사회문화적 맥락을 진로 및 노동시장 이행 등과 관련해 비판적으로 검토한다는 데에 의의가 있다. This collaborative autoethnography delves into the educational experiences of three master’s students majoring in Anthropology of Education. We, as researcher-participants, utilized our self-narratives and collaborative in-depth interviews to shed light on the complexities of becoming full-time graduate students. Our qualitative investigation showed that all three of us had experienced instances of educational inequality in and out of secondary schools. Those negative experiences were followed by academic curiosity, which in turn led to our aspirations to explore the root causes, processes, and solutions of the educational inequality after entering college. Also, using the metaphors of “street smart,” “volunteer,” and “megaphone” our narratives represent the desire to create specific types of identity while studying in graduate school. However, various challenges that had risen from our in-between position as students and professionals resulted in the complexity of constructing our imagined futures. Exploring the educational experiences of three graduate students through collaborative autoethnography, we found out a broader social context with regard to the hardships that Korean graduate students are facing. Specifically, the professional identity of graduate students is hardly recognized and most students are having difficulties in looking for employment after graduation. Based on these findings from our work, suggestions are provided for future research to examine the identity formation of diverse full-time graduate students in Korea considering the current higher education environment.

Objective-The purpose of the study was to develop the Korean version of the Stage of Change Readiness and Treatment Eagerness Scale for Smoking Cessation (K-SOCRATES-S) based on the Korean version of the Stages of Readiness for Change and Eagerness for Treatment scale (K-SOCRATES). This paper also demonstrates its reliability and validity among patients with nicotine dependence in South Korea. Methods-At seven healthcare promotion centers in Gyeonggi-do, 333 male smokers aged 20 to 70 who visited smoking cessation clinic were recruited for this study and the K-SOCRATES-S was administered. After three months, the number of respondents who successfully stopped smoking was assessed by testing their urine cotinine level. Subsequently, exploratory factor analysis was performed to verify the reliability and validity of the K-SOCRATES-S. Also, a logistic regression analysis was performed to examine the variables that can predict the successful cessation of smoking on subscales of the K-SOCRATES-S. Results-Exploratory factor analysis of the K-SOCRATES-S showed that the scale consisted of three factors: Taking Steps, Recognition, and Ambivalence. The scales measuring Taking Steps and Recognition in this scale had a significantly positive correlation with the scores observed on Kim’s smoking cessation motivation scale. The scales measuring Taking Steps and Recognition had a significantly negative correlation with Ambivalence. Overall, the results indicate that the K-SOCRATES-K scale showed high validity. Conclusion-The K-SOCRATES-S developed in the present study is highly reliable and valid for predicting a patient’s likelihood of success in quitting smoking among patients who want to cease smoking.

Kim, Hee Jin,Yang, Jin Ju,Kwon, Hunki,Kim, Changsoo,Lee, Jong Min,Chun, Phillip,Kim, Yeo Jin,Jung, Na-Yeon,Chin, Juhee,Kim, Seonwoo,Woo, Sook-young,Choe, Yearn Seong,Lee, Kyung-Han,Kim, Sung Tae,Kim, Oxford University Press 2016 Brain Vol.139 No.9

<P>Amyloid-beta deposition and cerebral small vessel disease are major contributors to age-related cognitive decline. In a longitudinal study of mild cognitive impairment, Kim et al. show that amyloid-beta and lacunes have differing effects on cognitive trajectories. Amyloid-beta has a greater impact on memory, and lacune number on frontal-executive function.Amyloid-beta and cerebral small vessel disease are the two major causes of cognitive impairment in the elderly. However, the underlying mechanisms responsible for precisely how amyloid-beta and cerebral small vessel disease affect cognitive impairment remain unclear. We investigated the effects of amyloid-beta and lacunes on downstream imaging markers including structural network and cortical thickness, further analysing their relative impact on cognitive trajectories. We prospectively recruited a pool of 117 mild cognitive impairment patients (45 amnestic type and 72 subcortical vascular type), from which 83 patients received annual follow-up with neuropsychological tests and brain magnetic resonance imaging for 3 years, and 87 patients received a second Pittsburgh compound B positron emission tomography analysis. Structural networks based on diffusion tensor imaging and cortical thickness were analysed. We used linear mixed effect regression models to evaluate the effects of imaging markers on cognitive decline. Time-varying Pittsburgh compound B uptake was associated with temporoparietal thinning, which correlated with memory decline (verbal memory test, unstandardized beta = -0.79, P < 0.001; visual memory test, unstandardized beta = -2.84, P = 0.009). Time-varying lacune number was associated with the degree of frontoparietal network disruption or thinning, which further affected frontal-executive function decline (Digit span backward test, unstandardized beta = -0.05, P = 0.002; Stroop colour test, unstandardized beta = -0.94, P = 0.008). Of the multiple imaging markers analysed, Pittsburgh compound B uptake and the number of lacunes had the greatest association with memory decline and frontal-executive function decline, respectively: Time-varying Pittsburgh compound B uptake (standardized beta = -0.25, P = 0.010) showed the strongest effect on visual memory test, followed by time-varying temporoparietal thickness (standardized beta = 0.21, P = 0.010) and time-varying nodal efficiency (standardized beta = 0.17, P = 0.024). Time-varying lacune number (standardized beta = -0.25, P = 0.014) showed the strongest effect on time-varying digit span backward test followed by time-varying nodal efficiency (standardized beta = 0.17, P = 0.021). Finally, time-varying lacune number (beta = -0.22, P = 0.034) showed the strongest effect on time-varying Stroop colour test followed by time-varying frontal thickness (standardized beta = 0.19, P = 0.026). Our multimodal imaging analyses suggest that cognitive trajectories related to amyloid-beta and lacunes have distinct paths, and that amyloid-beta or lacunes have greatest impact on cognitive decline. Our results provide rationale for the targeting of amyloid-beta and lacunes in therapeutic strategies aimed at ameliorating cognitive decline.</P>

Soil attenuation of the seepage potential of metallic elements (Cu, Zn, As(V), Cd, and Pb) at abandoned mine sites: A batch equilibrium sorption and seepage column study

Kim, Juhee,Hyun, Seunghun Elsevier 2017 Journal of hazardous materials Vol.339 No.-

<P><B>Abstract</B></P> <P>Soil attenuation of off-site leaching potential of metallic elements at the two abandoned mine sites was investigated using batch sorption and layered column studies. In batch study, the leachate concentration-specific sorption (<I>K</I> <SUB>d</SUB> <SUP>*</SUP>) by downgradient clean soils was in the order of Pb>Cu>Cd>Zn>As for DY site and Pb>As>Cu>Cd>Zn for BS site. In the layered (mine+clean) soil column, element elution was significantly reduced (e.g., no initial flush, retarded peak arrival, and lower peak concentration) while sulfate elution can be an indicator of the dissolution of sulfur-bearing minerals in mine soils. The greatest reduction was observed for Pb and Cu while the lowest was for Cd (2–19%) and Zn (6–51%), consistent with the batch data. Both the reduced elution at slow seepage and concentration drop after flow interruption support the time-limited propensity. In column segments, the sorptive elements (Cu, Pb, and As) were dominantly found in the inlet while less sorptive ones (Zn and Cd) in the outlet. Both batch and column data suggest that the element leaching with mine leachate movement can be greatly attenuated by the interactions with the surrounding downgradient soil during the seepage process.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Discharge of metals with leachate was greatly reduced by seepage through downgradient soils. </LI> <LI> Leachate acidity was also ameliorated during downward seepage. </LI> <LI> Negligible elution of Pb and Cu was due to their high selectivity on soil matrix. </LI> <LI> Both element release and its retention by clean soils were seepage rate-limited. </LI> <LI> Leachate sulfate levels can be an awareness of off-site mobilization of metallic elements. </LI> </UL> </P>

Reliability and Validity of the Korean Version of the Empathy Quotient Scale

JuHee Kim,이승재 대한신경정신의학회 2010 PSYCHIATRY INVESTIGATION Vol.7 No.1

Objective: The Empathy Quotient (EQ) is a self-reported test developed by Baron-Cohen et al. (2004) to measure the cognitive and affective aspects of empathy. The purpose of this study was to develop a Korean version of EQ and to establish its psychometric properties based on a representative Korean sample. Methods: The Korean version of EQ and its correspondence with another popular measure of empathy, the Korean version of the Interpersonal Reactivity Index (IRI), were evaluated in a sample of 478 volunteers (156 men, 322 women; mean age, 27.2 years). A test-retest study was conducted at 1 month on a selected sample of 20 subjects from the original sample. Correlation and confirmatory factor analyses were conducted. Results: The test-retest reliability was good, and the internal consistency was acceptable (Cronbach’s alpha=0.78). Positive correlations were found between the EQ and three subfactors of the IRI, perspective taking, empathic concern, and fantasy, and the total EQ score was negatively correlated with the personal distress subscale. The confirmatory analyses suggested that the three-factor structure offered a good fit to the data. Conclusion: These findings support the reliability and validity of the Korean version of the EQ.

Doping-Dedoping Interplay to Realize Patterned/Stacked All-Polymer Optoelectronic Devices

Kim, Juhee,Kang, Mingyun,Cho, Jangwhan,Yu, Seong Hoon,Chung, Dae Sung American Chemical Society 2019 ACS APPLIED MATERIALS & INTERFACES Vol.11 No.20

<P>One of the remaining keys to the success of polymer electronics is the ability to systematically pattern/stack polymer semiconductors with high precision. This paper reports the precise patterning and stacking of various polymer semiconductors with the assistance of a molecular oxidizing agent and reducing agent for donor and acceptor semiconductors, respectively. Such doping-induced solubility control methods have been previously well developed; however, practical applications to various optoelectronic devices have been limited. To pattern/stack various polymers in various dimensions, it is important to carefully design not only the doping method for desolubilizing polymer semiconductors but also the dedoping method for recovering the genuine characteristics of each polymer semiconductor. Based on a systematic approach for such a doping-dedoping interplay, various high-performance optoelectronic devices are demonstrated: (1) all-polymer complementary inverter pattern with a high gain of 176, (2) all-polymer planar heterojunction photodiode with green-selective nature and high specific detectivity over 10<SUP>12</SUP> Jones, and (3) all-polymer ambipolar transistor pattern with balanced hole and electron mobilities. The results of the study indicate the potential of practical application of the doping-dedoping interplay to lateral/vertical patterning of different polymer semiconductors with high precision.</P> [FIG OMISSION]</BR>

Characterization of TNNC1 as a Novel Tumor Suppressor of Lung Adenocarcinoma

Kim, Suyeon,Kim, Jaewon,Jung, Yeonjoo,Jun, Yukyung,Jung, Yeonhwa,Lee, Hee-Young,Keum, Juhee,Park, Byung Jo,Lee, Jinseon,Kim, Jhingook,Lee, Sanghyuk,Kim, Jaesang Korean Society for Molecular and Cellular Biology 2020 Molecules and cells Vol.43 No.7

In this study, we describe a novel function of TNNC1 (Troponin C1, Slow Skeletal and Cardiac Type), a component of actin-bound troponin, as a tumor suppressor of lung adenocarcinoma (LUAD). First, the expression of TNNC1 was strongly down-regulated in cancer tissues compared to matched normal lung tissues, and down-regulation of TNNC1 was shown to be strongly correlated with increased mortality among LUAD patients. Interestingly, TNNC1 expression was enhanced by suppression of KRAS, and ectopic expression of TNNC1 in turn inhibited KRAS<SUP>G12D</SUP>-mediated anchorage independent growth of NIH3T3 cells. Consistently, activation of KRAS pathway in LUAD patients was shown to be strongly correlated with down-regulation of TNNC1. In addition, ectopic expression of TNNC1 inhibited colony formation of multiple LUAD cell lines and induced DNA damage, cell cycle arrest and ultimately apoptosis. We further examined potential correlations between expression levels of TNNC1 and various clinical parameters and found that low-level expression is significantly associated with invasiveness of the tumor. Indeed, RNA interference-mediated down-regulation of TNNC1 led to significant enhancement of invasiveness in vitro. Collectively, our data indicate that TNNC1 has a novel function as a tumor suppressor and is targeted for down-regulation by KRAS pathway during the carcinogenesis of LUAD.

Analysis of Trans Fat in Edible Oils with Cooking Process

Juhee Song,Joohyeok Park,Jinyeong Jung,Chankyu Lee,Seo Yeoung Gim,HyeJung Ka,BoRa Yi,Mi-Ja Kim,Cho-il Kim,JaeHwan Lee 한국독성학회 2015 Toxicological Research Vol.31 No.3

Trans fat is a unsaturated fatty acid with trans configuration and separated double bonds. Analytical methods have been introduced to analyze trans fat content in foods including infrared (IR) spectroscopy, gas chromatography (GC), Fourier transform-infrared (FT-IR) spectroscopy, reverses-phase silver ion high performance liquid chromatography, and silver nitrate thin layer chromatography. Currently, FT-IR spectroscopy and GC are mostly used methods. Trans fat content in 6 vegetable oils were analyzed and processing effects including baking, stir-frying, pan-frying, and frying on the formation of trans fat in corn oil was evaluated by GC. Among tested vegetable oils, corn oil has 0.25 g trans fat/100 g, whereas other oils including rapeseed, soybean, olive, perilla, and sesame oils did not have detectable amount of trans fat content. Among cooking methods, stir-frying increased trans fat in corn oil whereas baking, pan-frying, and frying procedures did not make changes in trans fat content compared to untreated corn oils. However, the trans fat content was so low and food label can be declared as ‘0’ trans based on the regulation of Ministry of Food ad Drug Safety (MFDS) (< 2 g/100 g edible oil).
