민경아,박서욱 국제한국언어문화학회 2020 한국언어문화학 Vol.17 No.3

본 연구의 목적은 한국어 교육기관에서 이루어지고 있는 실시간 원격 화상 한국어 교육에서의 상호작용에 대한 학습자와 교사의 인식을 분석하여 향후 다양한 상호작용을 보장하는 강의의 개발 방향을 모색하는 데에 있다. 이를 위해 실시간 원격 화상 강의에서의 상호작용 분석 기준을 마련하고 실시간 원격 화상 한국어 강의 경험이 있는 학습자 74명을 대상으로 설문 조사를 실시하였으며 5명의 교사를 인터뷰하였다. 분석 결과, 학습자는 실시간 원격 화상 강의에서의 학습자-인터페이스 상호작용, 학습자-내용 상호작용, 학습자-교사 상효작용이 대체로 잘 이루어지고 있다고 느끼고 있었으며 학습자 간의 상호작용에 대해서는 타 상호작용에 비하여 부족하다고 느끼고 있었다. 또한 교사들은 수업 과정 전반에서 상호작용의 한계를 느끼고 있다고 응답하였다. 본 연구에서는 이를 토대로 수업 환경 개선과 실시간 원격 화상 강의에 적합한 평가 방안 개발, 학습자 간의 상호작용을 증대시키기 위한 장치와 학습자 동기 유발을 위한 장치 마련, 비실시간 상호작용의 확대, 원활한 실시간 원격 화상 강의를 위한 교사 교육을 제안하였다. This study aims to suggest ways to enhance interaction in real-time distance Korean language video lectures by analyzing learners’ and instructors’ awareness of interaction in Korean language education institutes. Thus, this study proposed criteria for the analysis of interaction in real-time distance video lectures. Further, 74 learners who had experience in real-time distance Korean language video lectures were surveyed, and five instructors who participated in real-time distance Korean video lectures were interviewed. The results of this survey show that learners scored high on learner-interface, learner-content, and learner-instructor interactions. Conversely, learner-learner interactions were comparably rated low. In addition, teachers reported that interactions is limited in real-time distance video education classes compared to in personal classes. Consequently, we suggest ways to improve the online classroom environment, develop suitable evaluation methods for real-time distance Korean language video lectures, increase interaction among learners, motivate learners’ and expand non real-time interaction between teachers and learners. We also delineate the need to fomulate adequate teacher training programs regarding real-time distance Korean language video lectures.

Spatial variation in the electronic structures of carpetlike graphene nanoribbons and sheets

민경아,성동철,류정아,김건,홍석륜 한국물리학회 2014 Current Applied Physics Vol.14 No.12

Graphene, when deposited on a supporting substrate with a step edge, may be deformed in the presence of the step edges of the substrate. In this study, we have investigated a spatial variation in the local electronic structure near the step region, by performing first-principles calculations for carpetlike armchair graphene nanoribbons (C-AGNR) and two-dimensional periodic carpetlike graphene sheets (PCGS). Our results indicate no practical difference in the local density of states (LDOS) between those of flat and step regions. Interestingly, however, the PCGS shows a remarkable variation in the LDOS with an external electric field (E-field). Furthermore, we also discuss the dependence of the direction and the magnitude of the applied E-field on the spatial variation in the LDOS.

Polar oxide substrates for graphene growth: A first-principles investigation of graphene on MgO(111)

민경아,Jinwoo Park,류정아,홍석륜,손알로이시우스 한국물리학회 2013 Current Applied Physics Vol.13 No.5

Given the recent excitement over the truly two-dimensional carbon “super” material e graphene, there is now much effort and focus on the various possibilities of engineering the band gap of graphene for its device applications. One possible and promising route will be to grow graphene directly on some nonmetallic substrates. In this paper, we address the atomic and electronic structure of various graphene structures on the polar MgO(111) using first-principles density-functional theory (DFT) calculations. We find that graphene generally interacts strongly with the O-terminated polar oxide surface, forming strong chemical bonds, inferred from both energetics and detailed density-of-states analysis. We compare our theoretical findings with available experimental results, offering a possible direction for future band gap engineering of graphene on such oxide substrates.

민경아,푸자,함송희,신명철 대한약학회 2018 Archives of Pharmacal Research Vol.41 No.6

Cancer is a leading cause of death worldwide. Despite many advances in the field of cancer therapy, aneffective cure is yet to be found. As a more potent alternativefor the conventional small molecule anti-cancerdrugs, pro-apoptotic peptides have emerged as a new classof anticancer agents. By interaction with certain membersin the apoptotic pathways, they could effectively kill tumorcells. However, there remain bottleneck challenges forclinical application of these pro-apoptotic peptides incancer therapy. In this review, we will overview thedeveloped pro-apoptotic peptides and outline the widelyadopted molecular-based and nanoparticle-based strategiesto enhance their anti-tumor effects.

A retrospective study was conducted to evaluate the appropriateness of total parenteral nutrition (TPN) for 200 hospitalized adult patients in Samsung Medical Center from January 1st in 1995 to June 31st in 1997. Standard criteria were modified and determined from those stated by AJHP (American Journal of Health System Pharmacy) and ASPEN (American Society of Parenteral and Enteral Nutrition). The justification for indications was appropriate in $35\%,\;44\%,\;and\;32\%$ of the patient's in 1995, 1996, and 1997, respectively, without significant improvement over the last two and half years. Before and during the administration of TPN, several monitoring indicators were well documented, and monitoring frequencies were increased over two and half years period. However, the majority of the monitoring indicators were not found in the standard criteria range of $90\%$. The monitoring indicators for electrolyte balance, $PO_4$ and Mg, were not measured appropriately and resulted in the complications which could have been prevented. The indicator for lipid tolerance, triglyceride and the indicator for hemorrhagic incidence, prothrombin time (PT), were not well documented in comparison with other indicators. The indicators for the improvement in nutritional status, albumin and total protein, were appropriate in $90\%$ of the patients. Determination of TPN formula was based on the laboratory data and chart reviews, and it was appropriate in $98\%$. But the administration of lipid and vitamin K for the prevention of essential fatty acid deficiency and hemorrhage, respectively, was not carried out appropriately when the administration of TPN was prolonged, lasting more than 7 days. When a patient returned to oral or enteral feeding, TPN was terminated. However, increase in albumin level or weight was rarely observed. In conclusion, healthcare professionals should all work as a team and active participation to provide optimized nutrition support for partners.

학술적 글쓰기에서의 시각 자료 활용에 대한 외국인 학부생 인식 연구

민경아,곽도형 이중언어학회 2022 이중언어학 Vol.89 No.-

This study aims to examines foreign undergraduate students’ perception of using visual materials in academic writing and discusses the implications for effective education of using visual materials. As a result of a survey of 100 foreign undergraduate students, we found that most respondents use various visual materials in academic writing without difficulty. However, 60% of the respondents had no educational experience using visual materials in academic writing and 74% of the respondents said that education on the use of visual materials was necessary. In particular, respondents said that they needed education on the use of visual materials included selecting the contents of visual materials for academic writing, reasoning based on visual materials, and selecting the type of visual materials appropriate for academic writing. Based on these results, we suggested that education on the use of visual materials should be provided to foreign undergraduates regardless of their major and that the function, effectiveness, and stage of use of visual materials should be included as the educational content. In addition, we mentioned that it is necessary to organize the educational content by level when conducting education using visual materials in academic writing. 본 연구의 목적은 학술적 글쓰기에서의 시각 자료 활용에 대한 외국인 학부생의 인식을 살펴보고 효과적인 시각 자료 활용 교육에 대한 시사점을 논의하는 데에 있다. 이를 위하여 외국인 학부생 100명을 대상으로 설문조사를 실시한 결과, 대부분의 응답자는 학술적 글쓰기에서 다양한 시각 자료의 유형을 어려움 없이 활용하는 것으로 나타났다. 그러나 응답자의 60%는 학술적 글쓰기에서의 시각 자료 활용에 대한 교육 경험이 없었으며 응답자의 74%는 학술적 글쓰기에서의 시각 자료 활용 교육의 중요성을 인식하고 있었다. 그러나 응답자의 60%는 시각 자료 활용에 대한 교육 경험이 없을 뿐만 아니라 응답자의 74%는 시각 자료 활용에 대한 교육이 필요함을 인식하고 있었다. 특히 응답자들이 요구하는 시각 자료 활용에 대한 교육 내용으로는 학술적 글쓰기에 필요한 시각 자료의 내용 선정, 시각 자료를 바탕으로 한 추론, 학술적 글쓰기에 적절한 시각 자료의 유형 선택 등이 있었다. 마지막으로 응답자의 62%가 학술적 글쓰기에서의 시각 자료 활용 교육을 받을 의사가 있다고 응답하였다. 본 연구에서는 이를 토대로 전공과 관계없이 외국인 학부생에게 시각 자료 활용에 대한 교육이 이루어질 필요가 있다는 것과 교육 내용으로 시각 자료의 기능, 활용 효과, 그리고 활용 단계가 포함되어야 함을 확인하였다. 그리고 학술적 글쓰기에서의 시각 자료 활용 교육을 실시할 때 교육 내용을 수준별로 구성할 필요가 있다는 점을 제안하였다.
