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.

This study aims to investigate the difference in the ‘substantives+predicate’ type of lexical collocation perception of Korean native speakers and highly proficient learners of Korean through a self-paced reading task. The study was performed on15 native speakers and 15 advanced learners with TOPIK level 6. This study analyzed the collected data and found three major perceptive differences. (ⅰ) Unlike native speakers, advanced learners have cognitive difficulties in lexical collocation; (ⅱ) advanced learners took a longer reaction time at window 4 than native speakers; (ⅲ) native speakers had significant differences between correct and incorrect sentences, whereas advanced learners did not. As a result, the study showed that learners’ perception of lexical collocation would be affected by both native language and target language. (Kyung Hee University)

김주희 ( Kim¸ Juhee ),강은주 ( Kang¸ Eunju ),박종호 ( Park¸ Jongho ) 한국초등과학교육학회 2021 초등과학교육 Vol.40 No.3

학생들의 지속적인 성장과 발전을 위해서 학교급에 따른 학습 내용의 연계성은 필수적이라 할 수 있다. 그러나 유아교육과 초등학교 과학과 교육과정의 연계성에 대한 연구는 상대적으로 부족한 편이다. 이러한 측면에서 유아교육에서 전체적으로 제시하고 있는 과학 관련 학습 내용과 초등학교 과학과 교과 과정 간의 연속성에 대한 분석이 선행될 필요가 있다. 본 연구에서는 2015 과학과 교육과정을 중심으로 14개의 소영역으로 구성하고, 유치원과 초등학교 과학교육의 핵심 내용을 대응 관계로 제시하였다. 그 결과, 유치원에서만 제시된 학습 내용, 초등학교에만 제시된 학습 내용, 유치원과 초등학교의 명확한 연관성이 보이는 학습 내용으로 분류할 수 있었다. 본 연구는 유치원과 초등학교 과학과 교육과정의 연계성에 대한 시사점을 제시하고 있다는 점에서 의미가 있다. For the continuous growth and development of students, continuity of learning content according to the school level is essential. However, research on the continuity of kindergarten education and elementary school science curriculum is relatively insufficient. In this respect, it is necessary to precede the analysis of the continuity between the science-related learning content presented in kindergarten education and the science curriculum in elementary school. In this study, the 2015 science curriculum was organized into 14 small sections, and the core contents of science education in kindergartens and elementary schools were presented as correspondence. As a result, it was possible to classify learning contents presented only in kindergarten, learning contents presented only in elementary schools, and learning contents showing a clear continuity between kindergarten and elementary school. This study is meaningful in that it presents implications for the continuity between the science curriculum of the kindergarten curriculum and the elementary school curriculum.

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.

<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>

Juhee Kim,Woonseo Baik,Gyeonghye Yoon,Sungsoo Park,Eui-Cheol Shin,Youngseung Lee 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

Winter radish is harvested in the middle of winter and eaten throughout the winter. It is characterized by its firm tissue and less spicy taste. This study was conducted to investigate the volatile components and sensory characteristics of four different kinds of winter radish harvested in Korea. The olfactory properties of the raw radish were identified through the electronic nose while a total of 13 sensory characteristics of the raw and blanched radish were profiled by 7 trained descriptive panelists. Methanetiol was the highest fragrant component out of 18 fragrance components detected in all samples, followed by pyridine. PCA results confirmed that each variety had its own aromas. In raw radish, no significant differences were observed among varieties for most of characteristics except for hardness. On the other hand, the blanched radish showed differences for hardness and crunchiness. According to the PCA, each sample had its own characteristics being located in a different quadrant in the PCA map. Therefore, winter radishes should be used appropriately considering the characteristics of the variety.

Kim Ji Na,박희진,Kim Myung Sub,Moon Juhee,Park Jae Hyung,Kim Eugene,Kim Young Hwan 대한초음파의학회 2022 ULTRASONOGRAPHY Vol.41 No.1

Purpose: The aim of this study was to evaluate the usefulness of strain elastography (SE) in the differential diagnosis of ruptured epidermal cyst and superficial abscess. Methods: This retrospective study included 34 patients with ruptured epidermal cysts and 17 patients with superficial abscesses who underwent ultrasonography (US) including SE. The SE characteristics were classified into four grades (1 to 4) according to elasticity. The largest length and height of the lesion and their ratio were evaluated on the US images. Involvement of more than half of the depth of the dermis and the presence of the submarine sign were assessed. Results: The inter-reader agreement of US and SE findings showed excellent or almost perfect agreement. The height, length, ratio of height to length, and more-than-half-depth sign did not significantly differ between ruptured epidermal cysts and superficial abscesses for either reader (reader 1, P=0.071, P=0.129, P=0.806, and P=0.102, respectively; reader 2, P=0.173, P=0.053, P=0.669, and P=0.060, respectively). The submarine sign was significantly more frequent in ruptured epidermal cysts than in superficial abscesses (both readers, P<0.001). The difference in SE scores between ruptured epidermal cysts and superficial abscesses, which are harder than ruptured epidermal cysts, was statistically significant (reader 1, P=0.046; reader 2, P=0.028). Conclusion: The SE score and submarine sign may be useful characteristics for distinguishing ruptured epidermal cyst from superficial abscess.

Rational design of a junction structure to realize an NIR-selective narrowband organic thin-film photodiode

Kim, Juhee,Yoon, Seongwon,Sim, Kyu Min,Chung, Dae Sung The Royal Society of Chemistry 2019 Journal of Materials Chemistry C Vol.7 No.16

<P>A color-filter-free near-infrared (NIR)-selective thin-film organic photodiode (OPD) is demonstrated by systematically controlling the correlation between the optical penetration region and the semiconductor junction depletion region. Poly[4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-<I>b</I>;4,5-<I>b</I>′]dithiophene-2,6-diyl-<I>alt</I>-(4-(2-ethylhexyl)-3-fluorothieno[3,4-<I>b</I>]thiophene-)-2-carboxylate-2-6-diyl] (PCE10):poly(3-hexylthiophene-2,5-diyl) (P3HT) or poly[(2,5-bis(2-hexyldecyloxy)phenylene)-<I>alt</I>-(5,6-difluoro-4,7-di(thiophen-2-yl)benzo[<I>c</I>][1,2,5]-thiadiazole)] (PPDT2FBT):poly[2-methoxy-5-(2′-ethylhexyloxy)-<I>p</I>-phenylene vinylene] (MEH-PPV) (p-complex) is used as a photoactive donor layer in conjunction with the [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as a photoactive acceptor layer with well-defined abrupt PN junction characteristics. The device architecture is rationally designed such that the optical penetration regions of visible photons within the p-complex are isolated from the depletion region of a PN junction due to their high absorption coefficients, while those of NIR photons efficiently overlap with the depletion region due to their low absorption coefficients. This enables high performance NIR-selective OPDs with a peak detectivity over 10<SUP>12</SUP> Jones centered at 705 nm or 780 nm depending on the chemical composition of the p-complex, while maintaining the thin film nature of the active layer, as well as efficient quenching of the photoelectric conversion of undesired visible photons. This is the first example showing that the narrowband NIR selectivity of a thin film OPD can be realized by controlling the relationship between the optical penetration region and depletion region rather than the thickness of the entire semiconductor.</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>
