        Reproducibility of Apparent Diffusion Coefficient Measurements in Malignant Breast Masses

        장미정,김선미,윤보라,안혜신,김수연,강은영,김성우 대한의학회 2015 Journal of Korean medical science Vol.30 No.11

        This study aimed to evaluate the reproducibility of apparent diffusion coefficient (ADC) measurements in malignant breast masses, and to determine the influence of mammographic parenchymal density on this reproducibility. Sixty-six patients with magnetic resonance findings of the mass were included. Two breast radiologists measured the ADC of the malignant breast mass and the same area on the contralateral normal breast in each patient twice. The effects of mammographic parenchymal density, histology, and lesion size on reproducibility were also assessed. There was no significant difference in the mean ADC between repeated measurements in malignant breast masses and normal breast tissue. The overall reproducibility of ADC measurements was good in both. The 95% limits of agreement for repeated ADCs were approximately 30.2%-33.4% of the mean. ADC measurements in malignant breast masses were highly reproducible irrespective of mass size, histologic subtype, or coexistence of microcalcifications; however, the measurements tended to be less reproducible in malignant breast masses with extremely dense parenchymal backgrounds. ADC measurements in malignant breast masses are highly reproducible; however, mammographic parenchymal density can potentially influence this reproducibility.

        The East Asian Influence in Ezra Pound’s Pre-Cathay Poetry

        장미정 서울대학교 미국학연구소 2011 미국학 Vol.34 No.1

        Since early in the twentieth century American poetry has exhibited an East Asian orientalism as an essential part of its makeup. This essay traces the East Asian influence on Ezra Pound’s poetry before the publication of Cathay in 1914. Ezra Pound began learning about Japanese and Chinese poetry even before his acquisition of the Ernest Fenollosa notebooks in 1913and made attempts to incorporate their themes, forms, and perspectives into his own poetry. As early as 1912, Ezra Pound discerned a “form of super-position” in Japanese haiku and tried to adopt this form in his own English-language poetry. He also picked up Chinese themes from pre-exiting translations of Chinese literature, such as those done by Herbert Allen Giles,and tried to incorporate them into his poetry. He even attempted to apply the Japanese-inspired form to Chinese-inspired subject matter in three out of the four Chinese adaptations and imitations he wrote in this period (“After Ch’u Yuan,” “Liu Ch’e,” “Fan Piece for Her Imperial Lord,” and “Ts’ai Chi’h”). These efforts contributed to an enhancement of the intensity,precision, and suggestiveness of his poetry and an improvement in the objectivity and impersonality of its mode of presentation. In this way Ezra Pound’s pre-Cathay poetry paved a way for American poets afterwards to naturalize themes, subject matters, techniques, and perspectives of East Asian origin into their poetry.

        고려대학교 공통교양 <글쓰기> 교육과정 개발 사례

        장미정,황정현,김혜령,오현화 민족어문학회 2020 어문논집 Vol.- No.88

        This study aims to introduce the curriculum development process of Korea University’s common liberal arts subject College Writing and to discuss the contents of education and curriculum operation method. Until 2017, Korea University’s common writing education subject was Thinking and Writing I․II, but it has been recently necessary for the university to revamp the writing curriculum while the university has been placing importance on improving writing skills in writing education. For this reason, the Institute for General Education of Korea University has conducted a research on the development of the writing subject curriculum. The institute surveyed the needs of students in Thinking and Writing II in the second semester of 2017 and developed the training content and operation method of College Writing by combining the main content of college writing education and the survey results. College Writing, which has been operated from the first semester of 2018, aims to foster academic writing skills and to train students how to write college reports through process-based writing. The 16-week curriculum consists of the theory of writing, problem solving activities, writing feedback, and workshops. This curriculum actively reflects the needs of the students, allowing them to practice various writing styles, including but not limited to writing college reports, essays or reviews. Moreover, students have been able to get more strengthened feedback on their writings from the professors. All the students can get the same quality of education since all professors teaching this subject use the same materials and teaching plans. 본 연구는 고려대학교 공통교양 <글쓰기>의 교육과정 개발 과정을 소개하고, 교육 내용과 교육 운영 방식을 논의하는 것을 목적으로 한다. 2017년까지 고려대학교의 글쓰기 공통교양 교과목은 <사고와표현Ⅰ,Ⅱ>로 운영되었으나, 최근 글쓰기 교육에서 쓰기 능력 향상을 중요하게 여기는 경향이 나타남에 따라 교과목 개편의 필요성이 대두되었다. 이에 고려대학교 교양교육원에서는 글쓰기 교과목 개편을 목표로 교육과정 개발 연구를 진행하였다. 2017년 2학기 <사고와표현Ⅱ> 수강생을 대상으로 요구 조사를 실시하였고, 대학 글쓰기 교육의 주요 내용과 요구 조사 결과를 종합하여 고려대학교 <글쓰기> 교과목의 교육 내용과 운영 방식을 개발하였다. 2018년 1학기부터 개설·운영된 <글쓰기>는 학문적 글쓰기 능력 함양을 목표로, 대학보고서 작성을 위한 실습 중심의 과정별 글쓰기 교육을 지향하고 있다. 16주 교육과정은 글쓰기의 이론, 문제해결활동, 첨삭지도, 워크숍으로 구성된다. 학습자 요구를 적극적으로 반영하여 대학보고서 외에도 에세이, 비평문 등 다양한 글쓰기를 경험할 수 있도록 하였으며, 첨삭지도가 강화되었다. 또한 교수자에게 통일된 교안과 교육 자료를 제공하여 <글쓰기>를 수강하는 학생들이 균질한 교육을 받을 수 있도록 하였다.

        Magnetic Resonance Imaging Factors Predicting Re-excision in Breast Cancer Patients Having Undergone Conserving Therapy

        장미정,김선미,윤보라,김성원,강은영,박소연,김지현,김영미,안혜신 대한자기공명의과학회 2014 Investigative Magnetic Resonance Imaging Vol.18 No.2

        Purpose : The aim of this study was to determine the magnetic resonance imaging (MRI) features associated with re-excisiondue to the presence of a positive margin after breast conserving therapy (BCT) in breast cancer patients. Materials and Methods: We reviewed the records of 286 consecutive breast cancer patients who received BCT betweenJanuary 2006 and December 2007. Among 246 patients who had undergone BCT, 38 (15.4%) underwent immediatefurther surgery due to positive margin status. We analyzed the MRI findings using χ2 test, Fisher’s exact test and t tests. Multivariate logistic regression was conducted for prediction of re-excision. Results: Tumor size (p < 0.001), lesion multiplicity (p = 0.003), and non-mass-like enhancement (NMLE) type on MRI (p <0.001) were associated with margin involvement in BCT. On preoperative MRI, larger size (≥ 5 cm) (odds ratio = 2.96),NMLE (odds ratio = 3.81), and multifocal lesions (odds ratio = 2.54) were positively associated with re-excision. In casesinvolving NMLE, segmental distribution was associated with a greater likelihood of immediate re-excision. Conclusion: Larger size, multiplicity, and NMLE on MRI are significantly associated with re-excision after BCT in breastcancer patients. For NMLE lesions, the segmental distribution pattern was predictive of re-excision.

        서울시민의 환경보건 위험인식과 정책 필요성에 영향을 미치는 요인

        장미정,김정훈,이은주,김규상 사단법인 대한보건협회 2019 대한보건연구 Vol.45 No.3

        Purpose: The purpose of the present study is to analyze risks perceived by Seoul citizens, opinions on environmental health risks, and the effects on risk perception and policy needs through a quantitative psychology method and to build a basic reference in establishing environmental health policies. Methods: Data were collected using an online questionnaire survey for 6 days in August 2017 from 2,000 adult men and women aged 19 or older, who had lived in Seoul for more than 1 year. The present study referenced a psychometric paradigm study for the risk perception tool, identified 20 perceived risks in the field of environmental health, and measured 6 risk characteristics. In addition, the present study added general perception and the needs of preventative policies, used factor analysis to reduce factors into two risk perception structures, and measured the size of their effects. Results: The average of Seoul citizens’ general perception about environmental health risks was calculated by age, gender, marital status and revealed that the risk they perceived as most hazardous was radioactive contamination. In regards to policy needs, the respondents said particulate matter needed policies most. There were statistically significant differences between the groups. 6 risk characteristics were categorized into two attributes—dread risk and controllable risk—and four different types. Higher dread risk and lower controllable risk had a larger effect on both risk perception and policy needs. Conclusions: A gender difference was observed in environmental health risks perceived by Seoul citizens, and general risk perception and policy needs varied depending on dread risk and controllable risk. When enforcing environmental health policies, it would be important to consider the above, identify priorities, and provide appropriate adjustments and interventions. 연구목적: 서울시민이 느끼는 위험인식과 환경보건위해에 대한 의견, 위험인식과 정책 필요성에 미치는 영향을 계량심리학적 방법에 따른 분석을 통해 환경보건정책 수립의 기초자료 구축을 목적으로 하였다. 연구방법: 자료는 서울시에 1년 이상 거주한 만 19세 이상 성인 남녀 2,000명을 대상으로 2017년 8월 총 6일간의 온라인 설문조사로 수집되었다. 위험인식에 관한 도구는 심리측정패러다임 연구를 참고하여 환경보건분야로 한정한 20개의 위해요소를 도출하고 6개의 위험특성으로 측정하였다. 또한 일반적인 위험인식과 예방 정책 필요성을 추가하고 요인분석을 통해 위험인식 구조를 2개로 축소한 후 그에 미치는 영향 정도를 측정하였다. 연구결과: 20개 환경보건위해요인에 대한 일반적인 위험인식 순위를 성별, 연령별, 혼인상태별 평균값 순으로 나열한 결과 방사능의 위험인식이 가장 높았고 정책 필요성 순위는 미세먼지가 가장 높았으며 항목마다 집단별로 유의한 차이가 있었다. 서울시민의 환경보건위해요인에 대한 서울시민의 일반적인 위험인식을 평균값에 따라 도출한 결과 방사능, 산업폐수, 환경호르몬 순으로 위험하다고 인식하고 있었다. 정책의 필요성에 대한 응답으로는 미세먼지, 자동차 배기가스, 산업폐수 순으로 필요하다고 응답하였다. 6개의 위험특성은 위험에 대한 두려운 정도와 위험의 통제가능성 정도의 2개의 속성과 4개 유형으로 분류되었다. 위험에 대한 두려운 정도가 높을수록, 위험에 대한 통제가능성이 낮을수록 위험인식과 정책 필요성 모두에 영향을 주는 것으로 나타났다. 결론: 서울시민이 체감하는 환경보건위해는 성별, 연령별, 혼인상태별로 차이가 있었으며, 위험의 두려운 정도와 통제가능성 정도에 따라 일반적인 위험인식과 정책 필요성이 변화하였다. 환경보건정책 집행 시 이러한 점을 고려하여 우선순위를 파악한 적절한 조정과 중재가 필요할 것이다.
