( Min Kyu Kang ),( Yongseon Cho ),( Minsoo Han ),( Sun Young Jung ),( Kyoung Min Moon ),( Jinyoung Kim ),( Ju Ri Kim ),( Dong Kyu Lee ),( Jun Hyung Park ),( So Hee Chung ) 대한결핵 및 호흡기학회 2016 Tuberculosis and Respiratory Diseases Vol.79 No.3

Since IgG4-related pancreatitis was first reported in 2001, IgG4-related disease has been identified in other organs such as salivary gland, gallbladder, thyroid, retroperitoneum and kidney; but lung invasion is rare. A 63-year-old man presented with hemoptysis at the pulmonary clinic and chest computed tomography revealed about 4.1 cm irregular shaped mass with spiculated margin at the left upper lobe. Despite no elevation of serum IgG4 level, he was finally diagnosed as IgG4- related lung disease by transthoracic needle biopsy. After treatment with oral glucocorticoids, hemoptysis disappeared and the size of lung mass was decreased.

How Does SNS Use Affect Task Performance? An Analysis of Objective, Self-report, and EEG Interpretation Measures

Jinyoung Min 한국경영정보학회 2016 한국경영정보학회 학술대회논문집 Vol.2016 No.11

As SNS use becomes prevalent, its effect on performance has received much attention. The previous literature takes either positive or negative views of SNS, arguing that it either decreases performance by taking time and effort away from work or increases performance by providing social benefits for enhancing performance. Since both can be true, this study conducts an experiment to investigate how SNS use during a task simultaneously disturbs and enhances its performance. For this purpose, this research adopts distraction-conflict theory, distinguishes the types of task as simple and complex, and analyzes data including electroencephalography data. The results overall suggest that, when doing a simple task, SNS use operates positively on performance due to the positive effect of psychological arousal. However, when doing a complex task, SNS use operates neither positively nor negatively because the negative effect of psychological arousal and the positive effect of reduced stress offset each other.

민진영 ( Min Jinyoung ),이은경 ( Lee Eunkyung ) 한국언어문화교육학회 2017 언어와 문화 Vol.13 No.4

This study was aimed at developing an online Korean course for graduate school students of UST(University of Science and Technology) and suggesting the direction for contents of an e-learning Korean course. This study was mainly focused on development of a distinguished educational course after making the best use of the characteristics of online education and also on distinctiveness as a Korean course for general education course in Korean universities. The result of the survey about demand of learners showed that the learners wanted to study Korean in daily situations, such as in school, office, for shopping or ordering food. They also needed a chance to check what they have learnt through different examples of listening and speaking as well as through online content tests. Based on the demand, the study designed the curriculum of two courses; Basic Korean 1 and Basic Korean 2 with 30 chapters each. This program contains daily Korean topics and different contents on academic Korean. Each chapter consists of ‘beginning’, ‘learning’, ‘evaluation’ and ’organization’. It provides sufficient incremental learning by situational category. The study expects to be applied for the development of a customized Korean e-learning course reflecting the learner’s demand.

본 연구의 목적은 한국어교육 분야의 질적 연구 중 내러티브 탐구 동향을 고찰하여 그 특징을 밝히고 향후 발전 방향을 모색하는 데 있다. 이를 위하여 한국어교육 분야에서 내러티브 탐구가 최초로 수행된 2010년부터 2020년 2월까지 석·박사 학위논문 및 국내 학술지를 검색한 후 원문을 검토하였다. 최종적으로 분석 대상 논문 41편을 선정한 후 연도와 유형별, 연구 주제, 연구 참여자, 연구 참여자 수, 자료 수집 방법, 면담 횟수에 초점을 두고 어떠한 연구가 이루어져 왔는지 분석하였다. 내러티브 탐구는 많은 연구가 이루어지지는 않았으나 해마다 조금씩 꾸준히 연구되고 있다. 연구 주제는 한국어 학습자와 교수자들의 경험 이야기가 가장 많았고, 적응, 정체성, 교사 효능감, 교육 방안, 의사소통, 동기를 주제로 한 연구 등이 있었다. 연구 참여자는 유학생이 참여한 경우가 가장 많았고 한국어 교사, 해외 학습 거주자, 여성결혼이민자, 외국인 근로자, 난민 아동들이 참여하였다. 연구 참여자 수는 1명에서 25명까지 다양했으나 주로 3~8명을 참여자로 선정한 경우가 많았다. 자료 수집 방법은 연구자와 참여자가 일대일 혹은 연구자와 여러 명의 참가자가 함께 하는 심층 면담이 가장 많았으며 참여 관찰이나 연구자의 저널 쓰기와 같은 현장자료가 같이 수집된 경우도 있었다. 면담 횟수는 참여자 개인별로 3회 혹은 2회를 실시한 경우가 가장 많았다. 본 연구는 그동안 한국어교육 분야에서 이루어진 내러티브 탐구 동향을 분석하고 앞으로 나아가야 할 방향을 제시하였다는 데 의의가 있다. The purpose of this study is to research the narrative inquiry trend among the qualitative studies in Korean language education, and to reveal its characteristics and to seek the direction of future development. To this end, we searched the master s and doctoral theses and domestic journals and the original text from 2010 to February 2020, when narrative exploration was first conducted in the field of Korean language education. 41 these to be analyzed were finally selected, and analyzed which study has been made by focusing on year, type, research topic, research participants, number of participants and method of data collection and numbers of interview. Not many narrative inquiries have been made but are being studied little by little every year. The largest number of Research topics were the stories experienced by Korean learners and professors, including adaptation, identity, teacher efficacy, education methods, communication and motivation. The largest numbers of participants were international students followed by Korean language teachers, overseas study residents, female marriage immigrants, foreign workers and refugee children. The number of participants in the study ranged from one to 25, but the group of three to eight were mostly selected as participants. The data collection methods most frequently used were in-depth interview in which one-on-one or multiple researchers and participants participate in, and some cases collect data along with field text such as participating observation or journal writing. The frequency of interview most used were 3 or 2 times by each participant. This study is meaningful in that it analyzes narrative inquiry trend which has been made in Korean language education and suggests its future direction.

The purpose of this study is to analyze the mock class of the Korean Practicum for the Academic Credit Bank System attendees and to understand the problems thereby providing the necessary information for an efficient mock class. To this end, a Korean mock class was divided into ‘the overall curriculum of the class, teachers' words and attitudes, interaction and use of additional materials' and observed for analysis. As a result of the analysis, it was found that the students had difficulties in preparing and proceeding with the contents of the mock class. It is important that there are many opportunities to actually get to know Korean language education and the training for specific and practical education on Korean grammar in advance to practicing in a Korean mock classes and to have the necessary skills as a pre-service Korean language teacher. This study is significant in that it has provided the information necessary to implement a better mock class by analyzing the difficulties and practical classes of Korean Practicum students.

민진영(Jinyoung Min) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.15

목적 본 연구의 목적은 사회통합프로그램에서 한국어를 가르치고 있는 한국어교원들의 교수 경험을 심층적이고 다면적으로 고찰해 보는 데에 있다. 방법 연구 방법으로 Clandinin과 Connelly가 제안한 질적 연구 방법 중의 하나인 내러티브 탐구 방법을 사용하여 대학 부설 어학기관에서는 일반목적 한국어를, 사회통합프로그램에서는 특수목적 한국어를 가르치고 있는 교원 5명을 대상으로 심층 면담을 실시하고 녹취하여 전사하였다. 그리고 면담 전사 자료를 여러 번 반복해서 읽으면서 계속해서 나타나는 패턴, 줄거리, 주제 등을 찾아내기 위해 영역 분석과 분류 분석 방법을 사용하여 자료를 분석하였다. 결과 연구 참여자 다섯 명의 사회통합프로그램 교수 경험을 분석한 결과 그들이 공통적으로 경험한 것은 ‘학습자들에게 공기와 같은 한국어 수업’, ‘쓰기가 딜레마인 수업’, ‘힐링과 고통 그리고 안쓰러움이 뒤따르는 수업’, ‘들어주려는 열린 마음이 필요한 수업’과 같이 4가지로 나타났다. 결론 본 연구는 한국어교원들의 사회통합프로그램 교수 경험을 세부적이고 구체적으로 탐색한 것에 의의가 있다. 본 연구를 통해 대학 부설 어학기관에서 실시되는 일반목적 한국어 수업과 사회통합프로그램에서 실시되는 특수목적 한국어 수업의 차이점 및 사회통합프로그램에서만 나타나는 특성에 대해 파악된 내용을 바탕으로 사회통합프로그램에서 한국어를 배우는 이민자들을 더 효과적이고 효율적으로 가르칠 수 있는 방안을 마련하는 데에 도움을 줄 수 있을 것이다. 또한 급격히 늘어나고 있는 사회통합프로그램 학습자들에 대한 이해를 돕고 이들을 위한 한국어교육의 기반을 잡는 기초 자료로 활용될 수 있을 것이다. Objectives The purpose of this study is to examine the teaching experience of Korean language teachers teaching Korean in an in-depth and multifaceted manner in Korea Immigration and Integration Program. Methods Using the narrative inquiry method, one of the qualitative research methods proposed by Clandinin and Connelly, in-depth interviews were conducted with five teachers teaching Korean for general purpose at university language institutions and Korean for special purpose in Korea Immigration and Integration Program. In addition, the data were analyzed using the domain analysis and taxonomic analysis method to find patterns, threads, and theme that continued to appear while reading the interview transcription data several times repeatedly. Results As a result of analyzing the experiences of five Korea Immigration and Integration Program teachers, there were four common experiences: Korean classes like air for learners, classes where writing is a dilemma, classes followed by healing, pain and regret, and classes that need an open mind to listen. Conclusions This study is meaningful in that it explored in detail and specifically the experience of Korean language teachers teaching Korea Immigration and Integration Program. This study will help to come up with a more effective and efficient way to teach immigrants learning Korean in the Korea Immigration and Integration Program based on the differences between general purpose Korean classes and special purpose Korean classes in Korea Immigration and Integration Program. In addition, it can be used as a basic material to help understand the rapidly increasing number of learners of Korea Immigration and Integration Program and lay the foundation for Korean language education for them.

세네갈 68년 5월 항쟁의 전개와 의의 - 프랑스 68혁명의 영향설을 중심으로

민진영(Jinyoung MIN) 프랑스학회 2018 프랑스학연구 Vol.0 No.87

Cet article consiste à examiner le déroulement et les valeurs de la révolte sénégalaise en Mai 68 ainsi que de ses diverses interprétations par l influence du mouvement de Mai 68 en France. Les étudiants de Dakar ont appelé à une grève illimitée et à un boycott des examens. La police a étouffé les émeutes sur le campus. Durant les combats de rue qui ont suivi, un élève a été tué et arrêté. Les syndicats se sont mis en grève pour soutenir les étudiants. Les manifestations étudiantes se sont transformées en une opposition au gouvernement sénégalais et à son président, Léopold S. Senghor. Le chef d’État, qui était aussi un poète, a fermé l université de Dakar et déclaré l état d urgence dans tout le pays. Cet évènement n a pas encore eu de dénomination exacte ni au Sénégal, ni en France bien qu’elle ait été appelée sous différentes appellations : la rébellion , la révolution , la démonstration , le mouvement ou la rébellion . Ces événements se sont déroulés presque simultanément avec Mai 1968 en France, et ont été influencés par l ancienne puissance coloniale, dont ils étaient cependant devenus indépendants. Mai 68 en France étant devenu un mouvement culturel révolutionnaire mondial qui est parti de Paris et qui s est propagé à Prague et à Chicago, il est certain que la révolte de Dakar faisait partie de Mai 68. Ceci étant, d un point de vue historique, la révolte Mai 1968 sénégalaise a été considérée comme un mouvement qui n’avait aucunement été influencé par Mai 68 en France. Cependant, le fait que la réponse apportée par le gouvernement sénégalais à cette révolte soit étroitement liée à la situation politique en France, peut être considéré comme étroitement liée à Mai 68. En outre, ne serait-ce que parce que le président Senghor a réprimé la révolte de Dakar sur le modèle de la méthode employée par Charles de Gaulle lors de la répression de la Révolution de Mai 68 en France, en l examinant soigneusement, on peut admettre que cette révolte de Dakar a été influencée par Mai 68. Toutefois, Senghor n a pas raison de dire qu elle a été impulsée par une force étrangère. Il serait approprié de dire que la résistance sénégalaise n’a pas été aidée par les mains de puissances étrangères, mais qu’elle a 158 프랑스학연구 87 naturellement rejoint dans ses actions le mouvement français de Mai 68, qui était devenu une révolte mondiale. Lors des manifestations du 68 mai au Sénégal, il est évident que les étudiants et travailleurs ont joué un rôle fondamental dans la revendication de la liberté et des droits en s’appuyant sur les valeurs et l’expansion mondiale de Mai 68. Cependant, ils ont mis davantage l accent sur les critiques de la situation à cette époque au Sénégal, à savoir, le régime néocolonialiste et la forte dépendance économique sur la France. Si l on examine attentivement la performance des personnages principaux de la révolte de Dakar : les difficultés en politique d’Abdoulaye Bathily, qui était un des représentants de cette révolte, une revendication continue de l’autosuffisance de N Diaye ou la déportation politique et la mort douteuse d Omar Blondin Diop, des liens pertinents entre la révolte de mai 1968 au Sénégal et de Mai 68 peuvent être trouvés

프랑스인 한국어 학습자의 특성 연구 : 교양한국어 담당 교수자의 심층 면담을 중심으로

민진영(Min, Jinyoung),조윤정(Cho, Yunjeong),김현주(Kim, Hyunjoo) 한국문화융합학회 2020 문화와 융합 Vol.42 No.6

이 논문의 목적은 프랑스인 학습자를 가르친 경험이 풍부한 한국어 교수자들을 대상으로 심층 면담을 실시하여 실제 프랑스인 학습자를 가르치면서 알게 된 이들의 특성을 파악한 후, 그들에게 적절한 교수 방안을 제시하는 데에 있다. 이를 위하여 A대학교에서 프랑스인이 대다수 포함된 교양한국어 강좌를 3년 이상 가르친 경험이 있는 교수자를 대상으로 ‘포커스 그룹 인터뷰(Focus Group Interview)’를 실시하였다. 본 연구의 참여자들이 교수 경험을 통해 느낀 프랑스인 학습자들의 특성은 한국어 학습에 다양한 동기를 가진 학습자, 한국어를 생소해하는 학습자, 독특한 학습 태도를 가진 학습자, 특별한 배려가 필요한 학습자로 분류할 수 있었다. 이러한 결과를 토대로 이들이 한국어를 더 잘 공부할 수 있도록 도와 주기 위해 교수자에게는 인내심을 가지고 기다려 주는 태도가 필요하고 프랑스어로 설명이 된 한국어 교재 및 프랑스인 학습자들의 특성이 반영된 교수학습 방법이 마련되어야 함을 제언하였다. 본 연구는 그동안 이루어지지 않았던 프랑스인 학습자들을 대상으로 한 교수 경험에 대한 진솔한 이야기를 바탕으로 프랑스인 학습자들의 한국어 학습 동기, 한국어 학습을 힘들어하는 이유, 학습 태도 등을 확인한 현장 연구라는 데 의의가 있다. The purpose of this study is to understand the characteristics of French learners of Korean language in the process of teaching. The study conducted in-depth interviews with Korean professors experienced in teaching French Korean learners to suggest a proper teaching plan. To this end, we conducted ‘Focus Group Interview’ with professors who have experienced in teaching Liberal Korean lecture, which included most of French learners for 3 years or more. Regarding the characteristics of French Korean learners, the participants of this study felt that learners can be classified into learners with diverse motivations for learning Korean, learners who are unfamiliar with Korean, learners with unique learning attitudes, and learners who need special consideration. To help their Korean learning better based on this result, it is suggested teachers should have patience, Korean textbooks that have descriptions in French should be used, and teaching methods should be planned considering the characteristics of French learners. This study is meaningful in identifying motivations French Korean learners, the reason why they feel learning Korean to be difficult, and their learning attitude based on the frank story regarding teaching experiences targeting French learners, which has not been conducted yet.
