본 연구는 아프리카계 미국인 학생의 한국에서의 성공적인 제 2 언어 학습 경험을 조사하였다. 한국에 많은 다문화 가정들이 있지만, 아프리카계 미국인 학생들의 제 2 언어 학습에 관한 연구는 부족하다. 과거에, 몇 몇 미국 연구자들은 아프리카계 미국 학생들을 학습부진아들로 분석하였지만, 그들의 제 2 언어 학습의 성공적인 사례에 대한 보고는 거의 없다. 질적 연구 방법론을 사용하여, 본 연구자들은 메리라는 한 아프리카계 미국인 여학생을 인터뷰하고 관찰조사 하였다. 또한, 메리의 어머니, 선생님, 그리고 친구들을 인터뷰하여, 메리의 한국어 발달에 대하여 조사하였다. 연구 결과로 메리의 한국어 화자로서의 노력은 가족, 한국사회, 그리고 친구들의 도움으로 이루어졌다. 메리는 언어 발달에 있어서 특별한 사회적 조직적 지원들을 경험했음을 또 한 묘사하였다. 본 연구는 한국에 있는 다문화 학습자들 교육에 대한 교육적 시사점을 논의하고, 아프리카계 미국인 학습자에 대한 부정적인 편견을 극복할 수 있는 가능성에 대하여 토론하였다. This case study examines the experiences of an African American student’s successful second language acquisition in Korea. There is an increasing number of multicultural families in Korea; but few research on African American students’ second language learning. In the past, some American researchers have analyzed African American students as academic underachievers for learning and there is a scarcity of research on African American students’ successfully acquiring a second language. With this qualitative research design, the researchers interviewed, and observed an African American girl named Mary. The researchers also interviewed Mary’s mother, teacher, and peers about Mary’s Korean language development. The results of this study revealed Mary’s determined efforts to become a fluent Korean speaker with support from family, community and friends. Mary underwent unique social and systematic supports for her language development. This paper concludes with the educational implication for multicultural language learners in Korea and the possibility to diminish the common stereotypes of African Americans as underachievers.

Ella Kidd(엘라 키드),Hye-Kyun Kim(김혜균) 한국콘텐츠학회 2018 한국콘텐츠학회논문지 Vol.18 No.7

본 연구는 정치·경제적 측면에서 일정궤도에 오르고 영어교육을 중시하는 두 나라의 학생 3명을 대상으로 진행하였다. 본 연구의 참가자들은 한국인 재학생 2명과 중국 유학생 1명이다. 연구의 목적은 이들이 해외에서 경험한 전반적인 언어 학습을 평가하는 것이었다. 본 연구의 참가자들은 비슷한 문화와 언어학습방식을 공유하지만 제2외국어 준비를 위한 접근방식은 서로 달랐으며, 이와 다르게 그들이 해외에서 공부하도록 동기를 부여한 내적 요인들은 동일했다. 그리고 교실 상황(평가), 사회적 환경(환경)및 학습전략도 서로 달랐다. 본 논문의 방법론은 표본 추출 기술을 이용한 전체론적 접근법을 사용하였다. 응답은 사전에 준비된 설문지와 구조화되지 않은 인터뷰에 의해 이루어졌고, 추후에 유도 추론 프로세스에 의해 분석되었다. 세 가지 즉, 책임, 문화, 의사소통의 충돌로 특정하였다. 이번 연구는 참가자들이 모국에서 영어학습에 대한 사전준비를 철저히 하면 할수록 해외에서의 성공에 큰 기여를 한다는 것을 보여 주었다. This study includes three students’ whose country origin is of a political and economic success, therefore the pursuit to learn English is important. The participants evaluated in this study are two students of Korean descent and one Chinese student. The purpose was to evaluate their overall language learning experiences outside of their home country. While the participants in this study share similar cultures and learning styles their process towards second language readiness is different. The internal factors (readiness) that motivated them to study abroad were synonymous. However, the classroom situations (assessment), social settings (environment), and strategies used were disparate. The methodology of this paper used a holistic approach with a snowball sampling technique. The responses were collected by a prepared questionnaire and unstructured interviews, then later analyzed by the inductive reasoning process. The 3 specific categories identified were despondency, culture and communication conflict. The present study revealed that the participants’ earlier preparation from their home country plays a significant contribution to their success abroad.

PRAAT Software: A Spech Interaction Tool to Analyze Teacher Voices

Ella Jane Kidd 중소기업융합학회 2019 융합정보논문지 Vol.9 No.9

본 논문은 음성 소프트웨어 기술의 사용을 통해 영어의 내부 영역 내에서 음성 상호 작용의 영향을 검토한다. 기본주 파수(F0)는 국적, 연령, 성별을 기준으로 원어민(연령 30-55세) 음성 효과를 분석해 얻었다. 이 연구에서 밝혀진 바에 따르 면, 백인 영국 여성(33세)과 백인 미국인 남성(55세)이 가장 많은 대화형 연설을 했다는 것이다. 기여 요인은 학생들이 언어 습득 연구를 통해 다양한 언어 스타일을 경험한 것이다. 이 연구의 결과는 평균 이상의 연속적인 말이 학생의 참여와 상호작용에 가장 중요하다는 데 동의한 Traunmüeller & Eriksson(1995) 및 이전 연구와 양립할 수 있다. Through the use of speech software technology, this paper examines the effects of voice interactions within the inner circle of English. The fundamental frequency (F0) was obtained by analyzing native speakers (aged 30-55) speech effects based on nationality, age, and gender. The findings within this study reveal that the Caucasian British female (age 33) and the Caucasian American male (age 55) produced the most interactive speech. The contributing factor is the students’ experience with various language styles throughout their language acquisition studies. The results of this study are compatible with Traunmüller & Eriksson (1995) and previous studies which agree that continuous speech above average is paramount towards student engagement and interactions.

Autonomous Driving Path Planning based on Sarsa-Dyna Algorithm

Aboul Ella Hassanien,Jennefer Mononteliza 사단법인 미래융합기술연구학회 2020 아시아태평양융합연구교류논문지 Vol.6 No.7

In autonomous driving path planning, ensuring the computational efficiency and safety of planning is an important issue. The Dyna framework in reinforcement learning can solve the problem of planning efficiency. At the same time, the Sarsa algorithm in reinforcement learning can be effective in guaranteeing the safety of path planning. This paper proposes a path planning algorithm based on Sarsa-Dyna for autonomous driving, which effectively guarantees the efficiency and safety of path planning. The results show that the number of steps planned in advance is proportional to the convergence speed of the reinforcement learning algorithm. The Sarsa-Dyna will be proposed. The analysis of convergence speed and collision times has been done between the proposed Sarsa-Dyna, Q-learning, Sarsa and Dyna-Q algorithm. The proposed Sarsa-Dyna algorithm can reduce the number of collisions effectively, ensure safety during driving, and at the same time ensure convergence speed.

박서연(Ella Seo Yeon Park),정병훈(Byung Hoon Chung),전익현(Ikhyun Jun),김태임(Tae-im Kim),서경률(Kyoung Yul Seo),김응권(Eung Kweon Kim) 대한안과학회 2022 대한안과학회지 Vol.63 No.2

목적: 백내장수술시 ARTIS?? PL E (Cristalens Industrie, Lannion, France) 인공수정체와 Tecnis?? ZCB00 (Johnson & Johnson Vision, Santa Ana, CA, USA) 인공수정체를 삽입한 환자들의 임상 결과를 비교하였다. 대상과 방법: 동일한 술자로부터 백내장초음파유화술을 받고 ARTIS?? PL E를 삽입한 33안(A군)과 Tecnis?? ZCB00을 삽입한 45안(B군)의 의무기록을 후향적으로 분석하였다. 수술 후 1, 3개월 되는 시점에서의 최대교정시력, 굴절력 및 고위수차를 수술 전과 비교하였다. 결과: 수술 전 최대교정시력은 A군과 B군 간 유의한 차이는 없었다(p=0.494). 수술 후 최대교정시력은 각각 logMAR 0.01 ± 0.05, 0.01 ± 0.04로 두 군 모두 유의미한 호전을 보였으나(p<0.001), 두 군 간 유의한 차이는 없었다(p=0.289, p=0.471). 수술 후 1, 3개월 경과한 시점에서 전체, 구면, 코마수차는 모두 수술 전과 비교하여 유의하게 감소하였다(p<0.05). 두 집단 모두 수술 1, 3개월 후 목표 굴절력 ± 0.50 diopters 이내가 확인되어 예측도 면에서 유의한 차이는 없었다(p=0.390, p=0.959). 또한, 각 그룹에서 수술 후 1, 3개월째 굴절력에는 통계학적으로 유의한 변화는 없었다(p=0.482, p=0.372). 결론: ARTIS?? PL E 인공수정체를 이용한 백내장수술 후 최대교정시력의 유의미한 향상을 보였으며, 수술 후 시력 변화 및 고위수차에서 기존에 임상효과가 검증되었던 Tecnis?? ZCB00과 대등한 결과를 보였다. Purpose: To compare the clinical outcomes of cataract surgery using the ARTIS?? PL E (Cristalens Industrie, Lannion, France) intraocular lens (IOL) and conventional Tecnis?? ZCB00 (Johnson & Johnson Vision, Santa Ana, CA, USA) IOL. Methods: This retrospective study examined patients who underwent in-the-bag implantation of either an ARTIS?? PL E (33 eyes, group A) or Tecnis?? ZCB00 (45 eyes, group B) IOL after phacoemulsification performed by a single surgeon. Best-corrected visual acuity (BCVA), spherical equivalent, and higher-order aberrations (HOA) were measured 1 and 3 months after cataract surgery. Results: Preoperative BCVA did not differ significantly in groups A and B. Postoperative BCVA at 1 and 3 months improved significantly (p < 0.001) in both groups compared to preoperative baseline BCVA. At 1 and 3 months postoperatively, total HOA, spherical aberration, and coma were significantly lower compared to the preoperative baseline HOA (p < 0.05) in both groups. However, there were no significant differences in the trefoil values 1 and 3 months postoperatively compared to the preoperative baseline in both groups. The absolute refractive error 3 months postoperatively was 0.27 ± 0.20 (group A) and 0.28 ± 0.20 (group B), both within ± 0.50 diopters of the targeted goal diopter; there were no significant differences in the accuracy or predictability of the IOL power calculation in both groups (p = 0.390, p = 0.959). The absolute refractive error 1 and 3 months postoperatively did not differ significantly; there were no significant differences in the stability of both IOLs (p = 0.482, p = 0.372). Conclusions: Conventional cataract surgery using the ARTIS?? PL E IOL significantly increased the BCVA, while obtaining comparable clinical results to the verified Tecnis?? ZCB00 IOL in postoperative visual acuity and HOA.

Change is Inevitable, Progress is Optional: Impact of FED Tapering Announcements on North African Equity Markets

Assoumou-Ella Giscard,Bastidon Cécile,Bonijoly Bastien 한국국제경제학회 2022 International Economic Journal Vol.36 No.2

We propose one of the first empirical evaluations of the transmission of the 2013–2015 Federal reserve Tapering announcements of assets purchases, to the stock markets of the three north African countries with the most advanced financial development: Egypt, Morocco, and Tunisia. We use two alternative announcement effects dummy variables: one constructed from econometric tests of individual announcements, the other constructed from the media coverage. In spite of a relatively low level of financial integration, the results of panel data tests show a significant negative impact of announcements, generally associated with the Federal Open Market Committee (FOMC) meetings rather than minutes. This result is in line with the literature on the domestic and international announcement effects of the information released by the FOMC, in the absence of discordance of tone between the meeting statement and the minutes. From the perspective of policy recommendations, the study of the interaction of Tapering announcements with domestic fundamentals shows interesting results. Fundamentals with favorable direct effects on equity markets dynamics could indirectly increase their vulnerability to announcement effects. Inflation, domestic investment and commercial openness show significant interaction effects in the opposite sense of their direct effects, some of which are superior to the direct effects.
