Purpose To evaluate the diagnostic performance of digital breast tomosynthesis (DBT) with the two-dimensional synthesized mammogram (2DSM), compared to full-field digital mammography (FFDM), for suspicious microcalcifications in the breast ahead of stereotactic biopsy and to assess the diagnostic image visibility of the images. Materials and Methods This retrospective study involved 189 patients with microcalcifications, which were histopathologically verified by stereotactic breast biopsy, who underwent DBT with 2DSM and FFDM between January 8, 2015, and January 20, 2020. Two radiologists assessed all cases of microcalcifications based on Breast Imaging Reporting and Data System (BI-RADS) independently. They were blinded to the histopathologic outcome and additionally evaluated lesion visibility using a fivepoint scoring scale. Results Overall, the inter-observer agreement was excellent (0.9559). Under the setting of category 4A as negative due to the low possibility of malignancy and to avoid the dilution of malignancy criteria in our study, McNemar tests confirmed no significant difference between the performances of the two modalities in detecting microcalcifications with a high potential for malignancy (4B, 4C, or 5; p = 0.1573); however, the tests showed a significant difference between their performances in detecting microcalcifications with a high potential for benignancy (4A; p = 0.0009). DBT with 2DSM demonstrated superior visibility and diagnostic performance than FFDM in dense breasts. Conclusion DBT with 2DSM is superior to FFDM in terms of total diagnostic accuracy and lesion visibility for benign microcalcifications in dense breasts. This study suggests a promising role for DBT with 2DSM as an accommodating tool for stereotactic biopsy in female with dense breasts and suspicious breast microcalcifications.

Shin, Jiwon,Cho, Kyungjune,Kim, Tae-Young,Pak, Jinsu,Kim, Jae-Keun,Lee, Woocheol,Kim, Jaeyoung,Chung, Seungjun,Hong, Woong-Ki,Lee, Takhee The Royal Society of Chemistry 2019 Nanoscale Vol.11 No.29

<P>The irradiation effect of high energy proton beams on tungsten diselenide (WSe2) ambipolar field-effect transistors was investigated. We measured the electrical characteristics of the fabricated WSe2 FETs before and after the 10 MeV proton beam irradiation with different doses of 10<SUP>12</SUP>, 10<SUP>13</SUP>, 10<SUP>14</SUP>, and 10<SUP>15</SUP> cm<SUP>−2</SUP>. For low dose conditions (10<SUP>12</SUP>, 10<SUP>13</SUP>, and 10<SUP>14</SUP> cm<SUP>−2</SUP>), the threshold voltages shifted to the negative gate voltage direction, and the current in the hole and electron accumulation regimes decreased and increased, respectively. However, the trends were opposite for the high dose condition (10<SUP>15</SUP> cm<SUP>−2</SUP>); the threshold voltages shifted to the positive gate voltage direction, and the current in the hole and electron accumulation regimes increased and decreased, respectively. These phenomena can be explained by the combined effect of proton irradiation-induced traps and the applied gate bias condition. Specifically, irradiation-induced positive oxide traps in SiO2 dielectrics play a role in enhancing electron accumulation and reducing hole accumulation in the WSe2 channel, whereas the irradiation-induced holes near the WSe2/SiO2 interface act as electron trapping sites, with enhancing hole accumulation and reducing electron accumulation in the WSe2 channel. This work will help improve the understanding of the effect of high energy irradiation on WSe2-based and other ambipolar nanoelectronic devices. In addition, this work shows the possibility of tuning the electrical properties of WSe2-based devices.</P>

Recasting Colonial Space - Naturalist Vision and Modern Fiction in 1920s Korea

Jiwon Shin 서울대학교 국제학연구소 2004 Journal of International and Area Studies Vol.11 No.3

  This essay examines the correlation between two important yet seemingly unconnected developments in colonial Korean culture and literature at the advent of the Cultural Rule: the growth of urban visual culture on the one hand, and the emerging literary aesthetics centering on naturalism on the other. As a case study to explore the link between these two developments, the essay analyzes the colonial space as it is represented in the 1920s fiction, particularly in the early writings of Y?m Sang-s?p.

다문화 도시의 다양성 관리와 ‘디아스포라 공간’

신지원(Shin, Julia Jiwon) 전남대학교 글로벌디아스포라연구소 2017 디아스포라 연구 Vol.11 No.1

지난 50년 동안 이민자의 지속적인 유입을 경험한 영국은 프랑스나 독일과 같은 이웃 국가와는 차별된 고유의 이민자 통합정책을 발전시켜왔다. 영국의 이민자 통합정책은 ‘통합과 공동체 화합(integration and community cohesion)’이란 정책 패러다임 안에서 중앙과 지방정부의 역할분담과 협의체를 통한 정책결정과정을 강조한다. 본 연구는 영국에서 다문화 도시의 모범사례로 잘 알려진 ‘레스터 모델’의 형성 배경을 좀 더 심도 있고 비판적으로 분석한다. 레스터는 도시의 인구 약 34만 명 중 절반이 넘는 인구가 비백인 이민자 출신으로 구성되어 있다. 본 연구는 레스터의 다문화 현황 및 관련 정책에 대한 현상적인 분석을 넘어 다문화 인구를 구성하는 디아스포라 형성의 역사적 배경을 살펴보고 지역의 ‘다양성’이 어떠한 방식으로 관리되어왔는지 살펴본다. 과거 이민자의 유입을 노골적으로 반대하고 인종차별적인 분위기가 만연했던 레스터 시가 효과적인 다양성 관리 제도와 정책을 발전시킬 수 있던 배경에는 인구학적(종족 및 종교구성의 다양화), 제도적(인종관계법 및 지방정부 책임성 강화), 경제적(에스닉 산업) 요인이 있다. 아울러 본 연구는 아브타 브라(Avtar Brah)의 ‘디아스포라 공간’ 개념을 차용하여 레스터의 다양성 관리 담론, 제도 및 실행에 있어 경제적, 정치적, 사회적 영역에서의 권력관계와 자리매김이 어떻게 작동해 왔고 경합해왔는지 살펴본다. Over the last 50 years, Britain has experienced a constant influx of migrants and developed its own unique migration integration policy that is different from its neighbours, such as France and Germany. The migrant integration policy in Britain is implemented within the policy paradigm of “integration and community cohesion”, which emphasises the policymaking process based on the division of roles between central and local governments. Taking a renowned British multicultural city, Leicester, as a case study, this paper critically examines the background of the ‘Leicester model’. Over the half of the total population in Leicester are non-white immigrants and their descendants. The paper scrutinises the historical background of the diaspora formation that constitutes the multicultural population of Leicester and the ways in which local ‘diversity’ have been managed. Leicester, which was blatantly opposed the influx of migrants in the past, was able to develop effective diversity management policy due to demographic (ethnic and religious diversities), institutional (local government’s commitment to racial relations and community cohesion), and economic (ethnic businesses) factors. By using the Avtar Brah’s concept of ‘diaspora space’, it also explores the ways in which power relations and social positioning in the discourse, institutions and practices of diversity management are constructed and contested in the economic, political and social spheres.

우리나라 영어 사교육 현장에 내재된 영어 식민주의: 초등 어학원의 사례

신지원(Shin, Jiwon),김태영(Kim, Tae-Young) 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.4

본 연구의 목적은 초등 영어 사교육 기관 종사자들의 영어교육에 대한 인식과 그들 간의 관계 속에서 벌어지는 사건들 속에 잠재되어 있는 식민주의의 양상을 해석하고 비판적으로 탐색하는 것이다. 이를 위해 예비 연구를 거쳐 초등 사설 영어 학원 관리자 2명, 원어민 강사 2명, 한국인 강사 2명을 대상으로 2017년 5-6월에 개인당 50-60분간 정성적 연구방법인 반구조화 면담을 실시하였다. 수집된 자료는 근거이론 (grounded theory)을 바탕으로 분석하였다. 본 연구 결과는 다음과 같다. 첫째, 관리자와 강사들 모두 영어는 경쟁 사회에서 생존을 위한 도구라고 인식하고 있었으며, 영어교육 시장의 과도한 수업료와 백인 우월주의에 대해 인식하고 있었다. 둘째, 원어민 강사와 한국인 강사에 대한 관리자들의 차별과 원어민 교사의 영어 사용과 문화자본에 대한 주관적 우위는 강사들 사이의 긴장을 심화시키는 것으로 나타났다. 이러한 연구 결과는 영어와 관련된 불평등에 주목하는 비판적 영어교육과 세계 영어(World Englishes)에 대한 인식 고양이 필요함을 나타내며, 원어민 강사 채용 시 외 모와 혈통을 중시하는 백인 원어민 우월주의를 비판적으로 재고해야 함을 시사하고 있다 Globalization has compelled the English language to become the leading international language. The English language as a lingua franca enables people in the world to communicate in a common language. On the other hand, the spread of English aggravates the inequalities among various languages and cultures around the globe. The purpose of this study is to investigate the inherent colonialism existing in the perception of English education and the relationships among employees at a private elementary English language institute. Semi-structured interviews were conducted with two administrators, two native English teachers, and two nonnative teachers. Findings are as follows. Various characteristics of colonialism were identified among the staff. In their perception of English education, they recognized English as a tool for survival in a competitive society. In addition, all participants were keenly aware of excessive tuition fees and the existence of preferences for Caucasians in the practice of recruiting and employing English teachers. The administrators’ discrimination and native supremacy intensified tensions among the employees. It was also revealed that native teachers had subjective superiority in their use of the English language and exercised cultural capital. These results imply that there is a critical need for English education to focus on inequalities related to English and education for World Englishes, and to reconceptualize the notion of considering appearance and heritage in relation to the recruitment of teachers.
