이지용 ( Lee¸ Jiyong ) 반교어문학회 2021 泮橋語文硏究 Vol.- No.58

본 연구는 뉴스 헤드라인에 나타난 인공지능에 대한 개념적 은유를 분석함으로써 이에 대한 개념화 양상을 분석하는 것을 목표로 하였다. 특히 인공지능을 존재론적 은유인 생명체로 인식하는 방식이 일반화되어 있다는 사실에 근거하여, 생명체 은유로 분석 범위를 한정하여 살펴보았다. 이를 위해 먼저 ‘인공지능’에 대한 관심도가 가장 높았던 시기를 확인하고, 다양한 언론사 뉴스를 검색할 수 있는 플랫폼을 활용하여 관련 기사를 추출하였다. 이러한 방식으로 검색한 기사의 헤드라인을 중심으로 하여 인공지능 관련 생명체 은유를 중심으로 그 핵심 은유와 하위 유형을 분류하였다. 분석 결과 [인공지능은 사람]과 [인공지능은 종족]으로 세분할 수 있었으며, 사람 은유와 관련하여서는 다시 [인공지능은 전문가], [인공지능은 학습자], [인공지능은 적] 등으로 구체화하였다. 종족 은유와 관련하여서는 인류를 위협하고, 인간과 경쟁하거나 비교되고, 인간보다 뛰어나거나 뛰어나지 못한 존재, 그리고 인간과 교류하는 존재로 개념화 내용의 특성을 밝혀내었다. 이러한 분석을 통해 인공지능을 생명체로서 인식하고 개념화하고 있는 양상을 구체화하였다는 점에서 본 연구의 의의를 찾을 수 있다. This study aimed to analyze the conceptualization aspect of AI by analyzing the conceptual metaphor for artificial intelligence that appeared in news headlines. In particular, based on the fact that the method of recognizing artificial intelligence as an ontological metaphor of life is generalized, the scope of analysis was limited to the metaphor of life. To this end, we first identified the period when the interest in 'artificial intelligence' was the highest, and extracted related articles using a platform that can search news from various media companies. Centering on the headlines of articles searched in this way, the core metaphors and subtypes were classified based on the metaphors of artificial intelligence-related life forms. As a result of the analysis, it was possible to subdivide [AI is human] and [AI is race], and in relation to the human metaphor, [AI is an expert], [AI is a learner], [AI is an enemy], etc. did. In relation to the racial metaphor, it revealed the characteristics of the conceptualization content as beings that threaten humanity, compete with or compare with humans, are superior or inferior to humans, and interact with humans. Through this analysis, the significance of this study can be found in that it embodied the aspect of recognizing and conceptualizing artificial intelligence as a living things.

목적 본 연구는 학업탄력성의 종단적인 변화 양상을 파악하고 이에 영향을 미치는 요인을 탐색하는 것을 목적으로 한다. 방법 이를 위해 한국교육종단연구(KELS) 2013의 초등학교 6학년부터 중학교 3학년까지 4시점의 데이터를 활용하여 전체 학생들의 각 시점별 학업탄력성에 따른 집단의 규모와 학업성취도를 파악하고, 학업탄력성의 변화를 살펴보았다. 또한 취약계층 학생들의 학업탄력성 변화 양상에 따라 유형을 세분화하고 학업탄력성의 변화에 영향을 미치는 요인을 탐색하기 위해 다층 다항 로지스틱 회귀모형 분석을 실시하였다. 결과 본 연구의 주요 결과는 다음과 같다. 첫째, 시간이 지날수록 비취약계층-우수 집단과 비학업탄력적 집단의 규모는 증가하는 한편, 학업탄력적 집단의 규모는 감소하는 경향을 보였다. 둘째, 초기에 학업탄력적 집단이었으나 시간이 지나 비학업탄력적 집단으로 이동하는 학생들의 규모는 그 반대의 경우에 비해 더 큰 것으로 나타났다. 셋째, 학업탄력성이 하락하는 유형이 비교적 높은 비율을 차지하였으며, 이러한 학생들은 초⋅중학교의 전환기 시점에서 학업성취도의 감소폭이 비교적 큰 것으로 나타났다. 넷째, 수업이해도, 학업과 관련된 여가 시간 활용, 교사의 학생 특성 파악 정도 등의 변인은 학업탄력적 유지 유형에 대해 정적인 영향을 미치는 것으로 나타났다. 결론 본 연구는 기술통계와 시각화 기법을 중심으로 전국의 초등학교 6학년부터 중학교 3학년까지의 4년간 전체 학생들의 학업탄력성에 따른 집단 변화 양상을 포괄적으로 탐색하였다는 의의가 존재한다. Objectives The purpose of this study was to explore longitudinal trends in academic resilience and characteristics associated with patterns of these trends. Methods Achievement data and survey data annually measured for the students from the 6th to 9th grades in the Korea Educational Longitudinal Study (KELS) 2013 were used for the analyses. Students at each time point were classified into one of the four groups defined by the status of academic resilience and relative proportion of students in each sub-group and their academic achievement were explored. In addition, multilevel-multinomial logistic regression model was employed to identify characteristics that predict the patterns of longitudinal trends of academic resilience for socio-economically disadvantaged class. Results The major results of this study are as follows. First, while the proportion of students who have shown excellent academic performance among socio-economically non-disadvantaged class and the proportion of students who have shown poor academic performance among socio-economically disadvantaged class have been increased over time, the proportion of academic resilient students who have shown excellent academic performance among socio-economically disadvantaged class has been decreased. Second, the proportion of students who have transitioned from academic resilient group to academic non-resilient group was larger than that of their counterparts, and the extent to which their academic achievement declined was highest during the time of transition from elementary school to middle school. Third, it was found that characteristics such as comprehension of class materials, the out-of-school study time, and teacher s understanding of student characteristics showed positive effect in predicting academic resilience. Fourth, There was a positive effect of the introjected regulation for students who have transitioned from academic resilient group to academic non-resilient group compared with students who have preserved academic non-resilient group. Conclusions This study showed implication in that it was comprehensively explored the longitudinal group change trends according to academic resilience from 6th grade to 9th grade using descriptive analysis and visualization.

Neointimal hyperplasia (NIH), which is a commonly followed complication after cardiovascular surgery, leads to abnormal proliferation of smooth muscle cells in the tunica media due to endothelial damages and inflammatory response, resulting in restenosis and occlusion. For enhanced delivery of anti-proliferation drug to the tunica media with localized way, perivascular microneedle (MN) devices have been developed including MN cuff and wrappable MN mesh using biodegradable PLGA, showing enhanced NIH reduction with perivascular penetration. However, their tensile property including Young’s modulus and elongation needed to be modified to minimize mechanical constriction to the vascular tissue for vascular integrity. In this study, highly stretchable silk MN mesh was developed and their feasibility was evaluated with ex vivo insertion tests for localized drug delivery to the tunica media. The mechanical interaction between silk MN and rabbit abdominal aorta was analyzed with both infinite and blood pulse modeled insertion tests and tunica adventitia penetrability, an epidermal layer of the aorta, was evaluated with histopathological demonstration. As a result, tunica adventitia penetration was induced with 100 repetitive pulsatile movements with 3.58 mN of initial insertion and 3.56 mN of pulsatile induced force. Finally, in vivo comparative animal study was performed by applying silk MN mesh to the endothelially damaged blood vessel and showed enhanced efficacy for NIH reduction with multiple vascular penetrations.

In this study, we will analyze the status and requirements of both teachers and students to present effective measures for evaluation in college Korean classes. We will also present a mobile-based on-off blended speaking assessment model as an effective evaluation method. This approach will enable the creation of a database of customized learning and diagnosis, prescriptions, and both assessment questions and learner answers, all of which are difficult to implement in the current classes. Furthermore, assessing the ability of learners online will allow more time for offline classroom classes, which will not only improve the quality of the classes, but will also reduce the burden of teachers on the evaluations while providing accurate evaluations and sufficient feedback. As a result, it is expected that a useful foundation for the teaching, learning, evaluation, and utilization of information technology will be provided by accumulating all related data.

‘언어와 매체’ 교과서에 제시된 의미 관계 교육 연구

이지용(Lee, Jiyong) 중앙어문학회 2021 語文論集 Vol.87 No.-

이 연구는 고등학교 ‘언어와 매체’ 교과서의 문법 교육에서 제시되고 있는 의미 관계 교육의 내용을 비교 분석해 봄으로써, 그 현황을 살펴보고 발전적인 방향성을 모색하는 것을 목적으로 한다. 2015 개정 교육과정에서는 국어를 고등학교 공통 과목으로 두고, 일반 선택과 진로 선택으로 선택 과목을 이원화하였다. 문법 영역에서 무엇보다도 눈에 띄는 변화는 ‘언어와 매체’ 과목이다. 기존 ‘독서와 문법’에서 ‘독서’는 별도의 과목으로 설정되고 문법이 ‘언어와 매체’ 과목으로 설정된 것이다. 본 연구에서는 2015 개정 교육과정에서 새롭게 설정된 ‘언어와 매체’ 과목의 문법 영역에서 다루어지고 있는 의미에 대한 교육 내용이 단어의 의미 관계를 탐구하고 적절한 어휘 사용에 활용한다는 성취 기준에 부합하게 구성되어 있는지에 대해 5종의 교과서를 비교하여 분석하고자 한다. 이를 바탕으로 의미 관계에 대한 교육 내용이 어떠한 방향으로 설계되어야 하는지를 논의하고자 한다. The purpose of this study is to compare and analyze the contents of semantic relation education included in the grammar education of high school “language and media” textbooks, in order to examine the prevailing situation and to seek a developmental direction. In the 2015 revised curriculum, Korean was set as a common subject in high schools, and the elective subjects were categorized into general and career selection. The most notable change in the grammar section was the subject “Language and Media.” In the existing subject “Reading and Grammar,” “reading” is considered as a separate subject, while grammar has been included under “Language and Media.” This study examines whether the educational contents of the meanings covered in the grammar section of the newly established “Language and Media” subject in the 2015 revised curriculum meet the achievement standards of exploring the semantic relationship of words and the use of appropriate vocabulary. The study compares and analyzes five textbooks, as part of efforts to derive considerations regarding the direction in which educational content on semantic relationships should be designed.
