Navigating ChatGPT’s Challenges to English Writing Education: Finding a Path Forward

정혜란 현대영미어문학회 2023 현대영미어문학 Vol.41 No.3

This paper examines the transformative effects of ChatGPT on both general and English writing pedagogy in higher education as it ushers in an era of redefined writing practices. Rather than detailing its practical application as an empirical study outcome, this research aims at a reflective investigation of the challenges that ChatGPT poses for writing technology and English writing pedagogy. Drawing from a blend of online references and a limited number of scholarly publications on ChatGPT’s role in writing instruction, the paper attempts to forecast its influence on composition methodologies. The discussion also extends to possible reconstructions in English writing instruction for both native speakers and Korean EFL learners.

In order to explore the tendency that the meaning extension of Korean spatial adjectives shows, this study established the meaning extension classification criteria based on the principles of meaning extension presented in the previous studies, and analyzed the distribution aspects of meaning expansion types. The analysis confirmed that the distribution of the extended meaning of Korean spatial adjectives was disproportionate in terms of macroscopic aspects and that it was concentrated on specific types. From a microscopic point of view, it can be seen that meanings of Korean spatial adjectives were the most distributed in the non-temporal space among abstract spaces. Especially, the extended meanings are overwhelmingly distributed in the types of ‘tangible/intangible->non -temporal space’. In addition, the analysis on the distribution of meanings of spatial adjectives belonging to the ‘tangible/intangible ->non-temporal space’ type revealed that the human space and non-human space had the same distribution rates and the distribution rate of human intrinsic space was higher than the human extrinsic space. The study also found no significant difference in the distribution rates of the intrinsic and non-human space. 본 연구는 한국어 공간형용사의 의미 확장의 경향성을 모색해 보기 위하여 기존의 연구에서 제시한 의미 확장 원리에 기반하여 의미 확장 분류 기준을 정립하고, 의미 확장 유형의 분포 양상을 고찰하였다. 분석 결과, 거시적 측면에서 한국어 공간형용사의 확장 의미의 분포는 불균형적인 양상을 보이고 있었으며 특정된 유형에 집중적으로 분포되어 있음을 확인할 수 있었다. 미시적 측면에서 보면 한국어 공간형용사는 추상 영역 중 非시간 영역으로 의미가 가장 많이 분포되어 있었으며 특히 ‘유/무형물->非시간 영역’ 유형에 확장 의미가 압도적으로 많이 분포되어 있음을 알 수 있었다. 또한 ‘유/무형물->非시간 영역’ 유형에 속하는 공간형용사의 의미 분포율을 살펴본 결과 인간적 영역과 非인간적 영역의 의미 분포율이 같게 나타났고, 인간의 내재적 영역이 인간의 외재적 영역보다 분포율이 더 높았으며 인간의 내재적 영역과 非인간적 영역의 분포율은 큰 차이를 보이지 않는다는 것을 파악할 수 있었다.

개념적 혼성 이론을 통한 한·중 명암(明暗) 형용사의 의미 확장 및 의미 구성 양상 대조 연구

정혜란 서울대학교 국어교육연구소 2020 국어교육연구 Vol.46 No.-

The purpose of this study is to analyze the meaning extension and meaning construction of brightness adjectives focusing on “밝다,” “어둡다,” “亮,” “暗” in Korean and Chinese using the conceptual blending theory and investigate both similarities and differences. The results showed that the semantics of “밝다” and “亮,” “어둡다” and “暗” are both extended from the subjects of light to color and space (place) and from the concrete field to the abstract. Additionally, “어둡다” and “暗” are both extended to the subject of “one area.” These three points are similar. The difference is that the semantics of “밝다” are extended to subjects such as “future,” “etiquette,” “character, expression, atmosphere,” “eyesight, hearing,” “one area,” “world, society,” but the semantics of “亮” are extended to subjects such as “voice” and “heart, mind.” And the semantics of “어둡다” are extended to subjects such as “eye,” “personality,” “future,” “character,” ”expression,” “atmosphere,” “eyesight, hearing,” “world, society,” but the semantics of “暗” are extended to subjects such as “heart, mind.” 이 연구의 목적은 한·중 명암 형용사 중 ‘밝다’, ‘어둡다’, ‘亮’, ‘暗’을 중심으로 의미 확장 및 의미 구성 양상을 개념적 혼성 이론을 통해 분석하고 공통점 및 차이점을 규명하는 것이다. 분석 결과, 밝다’와 ‘亮’, ‘어둡다’와 ‘暗’은 빛 주체에서 빛깔과 공간(장소) 주체로 확장된다는 점, 주체가 모두 구체 영역에서 추상 영역으로 확장된다는 점, 그리고 ‘어둡다’와 ‘暗’은 모두 ‘어떤 분야’라는 주체로 확장된다는 점이 동일함을 파악할 수 있었다. 차이점을 살펴보면 ‘밝다’는 ‘미래’, ‘예의’, ‘성격, 표정, 분위기’, ‘시력, 청력’, ‘어떤 분야’, ‘세상, 사회’ 주체로 의미가 확장되는 반면에 ‘亮’은 ‘소리’, ‘마음, 생각’ 주체로 의미가 확장되는 양상을 보였다. 또한 ‘어둡다’는 ‘눈’, ‘성품’, ‘미래’, ‘성격, 표정, 분위기’, ‘시력, 청력’, ‘세상, 사회’ 주체로 의미가 확장되는 양상을 보였지만 ‘暗’은 ‘마음, 생각’ 주체로 의미가 확장되는 차이를 확인할 수 있었다.

A porous nickel-tin nano-dendritic electrode, for use as the anode in a rechargeable lithium battery, has been prepared by using an electrochemical deposition process. The adjustment of the complexing agent content in the deposition bath enabled the nickel-tin alloys to have specific stoichiometries while the amount of acid, as a dynamic template for micro-porous structure, was limited to a certain amount to prevent its undesirable side reaction with the complexing agent. The ratios of nickel to tin in the electro-deposits were nearly identical to the ratios of nickel ion to tin ion in the deposition bath; the particle changed from spherical to dendritic shape according to the tin content in the deposits. The nickel to tin ratio and the dendritic structure were quite uniform throughout the thickness of the deposits. The resulting nickel-tin alloy was reversibly lithiated and delithiated as an anode in rechargeable lithium battery. Furthermore, the resulting anode showed much more stable cycling performance up to 50 cycles, as compared to that resulting from dense electro-deposit with the same atomic composition and from tin electrodeposit with a similar porous structure. From the results, it is expected that highly-porous nickel-tin alloys presented in this work could provide a promising option for the high performance anode materials for rechargeable lithium batteries.

유동성 레진의 교합면 열구내 침투도와 미세누출 평가

정혜란,임성옥,이상호,이난영,Cheong, Hyeran,Im, Sungok,Lee, Sangho,Lee, Nanyoung 대한소아치과학회 2017 大韓小兒齒科學會誌 Vol.44 No.1

The aim of this study was to compared the penetration scores and microleakage levels of flowable resin in comparison to resin-based pit and fissure sealant. A total 120 extracted premolars were used and classified with group I (resin-based pit and fissure sealant), group II (flowable resin), group III (bonding agent + flowable resin), IV (fissurotomy + bonding agent + flowable resin) depending on the materials and the application methods. The penetration scores of the group treated with flowable resin following fissurotomy were similar to those of the group treated with resin-based sealant, but higher compared to those of the other groups treated with flowable resin without fissurotomy or bonding agent. The group treated with flowable resin following fissurotomy also exhibited the lowest microleakage levels. The group treated with resin-based sealant and the one treated with a bonding agent prior to the application of flowable resin showed similar microleakage levels. In conclusion, flowable resin may be applied as a pit and fissure sealant, and its application along with fissurotomy could increase the penetration scores. 본 연구의 목적은 유동성 레진의 교합면 열구에서의 침투도와 미세누출을 평가하여 치면열구전색제로서의 사용 가능성을 규명해 보고자 하는데 있다. 발거된 120개 치아를 4개 군으로 분류하고 I군은 대조군으로 레진계 치면열구전색제로 전색, II군은 유동성 레진으로 전색, III군은 상아질접착제를 도포한 후 유동성 레진으로 전색, IV군은 열구성형술을 시행하고 상아질접착제를 도포한 후 유동성 레진으로 전색하여 열구 내로의 침투도와 미세누출을 비교 평가하고 주사전자현미경으로 침투 및 접착상태를 관찰하였다. 유동성 레진의 열구내 침투도나 미세누출은 레진계 전색제에 비해 낮게 나타났으나 상아질접착제를 도포하거나 열구성형술을 시행한 후 상아질접착제를 도포한 경우는 레진계 전색제와 침투도의 차이가 없었으며 미세누출은 더 작게 나타났다. 주사전자현미경상에서 열구의 형태나 열구성형술의 여부에 따라 침투도의 차이가 관찰되었으며 상아질접착제를 사용하지 않은 일부 유동성 레진 시편에서는 법랑질 표면과 긴밀한 접착이 이루어지지 않았다. 이상의 결과를 종합해보면 유동성 레진은 치면열구전색제로서의 적용이 가능하며 열구성형술과 상아질접착제를 사용한다면 침투도를 높이고 미세누출을 줄일 수 있을 것으로 사료된다.

Reflections on the Interface between Native Son and Native Speaker

정혜란 미국소설학회 2022 미국소설 Vol.29 No.2

This paper examines the interface that splits apart yet at the same time links Native Son and Native Speaker, which unmistakably parallel each other in genre and theme in addition to their titular ties. In the first half of this Native Son/Native Speaker study, I investigate the complex and nuanced gap between the two texts, especially in relation to the matter of the unauthorized nativeness in white America, and also the direct clashes between Koreans and African Americans in the 1992 LA riots. In order to bridge the apparent gap between the two non-white minority groups, in the second half of this intertextuality study, I explore the unarticulated intersection of the African-Korean American texts by addressing self-effacement, the distinct feature shared by the subject formation of Green and Henry Park who appear, respectively, as a marginal African American character in Native Son and as a Korean American protagonist in Native Speaker. The main focus of this part is to examine the specific ways in which white surveillance culture exerts substantial influence on the distinct mode of the non-white subject formation, the correlation between surveillance culture and identity in a racially contextualized American society, so to speak. This Native Son/Native Speaker study thereby aims to contribute to a field of Afro-Asian intersection scholarship that is insufficient, compared to other cross-racial intersection scholarship within the field of American literary studies.
