조영주,양윤수,윤용주,권삼현,홍기환,Cho, Young-Ju,Yang, Yoon-Su,Yoon, Yong-Joo,Kwon, Sam-Hyun,Hong, Ki-Hwan 대한후두음성언어의학회 2009 대한후두음성언어의학회지 Vol.20 No.1

본 교실에서 1988년 1월부터 2007년 12월까지 시행했던 후두미세수술 4201례중 수술 후 성대낭종으로 확진된 212례를 대상으로 다음과 같은 결과를 얻었다. 1) 전체 후두미세수술 4,201례 중 성대낭종이 차지하는 비율은 212례로 5.04%였다. 2) 성대낭종 212례 중 유표피낭종은 56례(26.4%), 저류낭종이 156례(73.6%)를 차지하여 미미하지만 지속적인 저류낭종의 증가 추세를 보이고 있었다. 3) 성별분포는 212례의 성대낭종 중 여성이 135례(63.7%), 남성이 77례(36.3%)로 여성에 호발하였으며 최근에는 남녀 비율의 차이가 감소해가는 추세를 보이고 있었다. 4) 이학적 검사소견으로서 유피낭종은 술 전 이학적 검사상 56례 중 불과 33례(58.9%)에서 낭종을 의심할 수 있었고 저류낭종은 술 전 낭종을 의심할 수 있었던 경우가 156례중 70례로 44.9%에 불과해 성대낭종은 술 전 진단이 용이하지 않았다. 5) 병리조직학적 검사상 유표피낭종 내부에 PAS 음성인 케라틴과 콜레스테롤양(cholesterol-like)물질이 중층 편평상피로 구성된 막에 둘러 싸여 있는 양상을 보였고 저류낭종은 내부에 PAS 양성인 점액분비물을 포함하고 있는 원주 또는 입방세포로 구성된 막으로 이루어져 있었다. 6) 애성 발생과 관련된 유발 요인으로는 성대과용 또는 음성남용과 관련된 경우가 212례 중 80례(37.7%)로 성대과용이 주요한 유발인자로 생각된다. 7) 발병부위는 대부분 막성유리연의 중간부 및 전방부 1/3에서 발생하였고 수술 결과는 저류낭종 150례 중 54례(36.0%)에서만 낭종의 파열 없이 완전제거가 가능하였으며 유표피낭종 54례 중에서는 41례(75.9%)에서 낭종의 파열 없이 완전제거가 가능했던 것으로 나타나 저류낭종이 유표피낭종에 비해 낭종을 파열시키지 않고 완전히 제거하는 것이 더욱 어려움을 알 수 있었다. 따라서 저류낭종의 경우 낭종의 절제가 어려운 경우 수술방법으로 조대술(marsupialization)을 시행하는 것도 의미가 있을 것으로 사료된다. Background and Objectives: Intracordal cysts may occur secondary to voice abuse and overuse or may be secondary to a remnant of epithelium trapped within the lamina propria. They may occur spontaneously or may be associated with poor vocal hygiene. As the cyst enlarges it can start to significantly affect the vibratory region of the vocal fold. With the advancement of the microsurgical technique and the laryngeal stroboscopy, correct diagnosis of intracordal cyst have been increased. The aims of this study is to review the important clinical characteristics of the intracordal cyst. Materials and Methods: In the present study, 212 cases of the intracordal cysts were treated by the microsurgical technique. These lesions were diagnosed before the operation with indirect laryngoscopy, laryngeal endoscopy, laryngeal stroboscopy and confirmed with the findings observed during operations and the results of the biopsies. Results : The intracordal cysts were 212 cases in the 4,20 I patients who underwent laryngeal microsurgery (5.04%). Ductal cysts were 156 cases and epidermoid cysts were 56 cases. The lesions are more frequent in women and anterior third of true vocal cord is more frequently involved site. With the preoperative laryngoscopic examination, the intracordal cysts were mostly misdiagnosed as other disease of the vocal cord such as vocal polyps or nodules. And main cause of intracordal cysts was thought of vocal abuse. From view of the surgical approach, Ductal cysts was difficult to remove completely than epidermoid cyst without cystic wall rupture. Conclusion : Intracordal cysts are very similar to the other mucosal disorders of the vocal cord and it may be misdiagnosed as vocal polyps or nodules, frequently. Therefore careful preoperative examinations for the vocal cord lesions with stroboscopy and other endoscopic instruments are important part of the correct diagnosis. An ideal treatment is enucleation of the cysts without rupture of the cystic wall or injury of the lamina propria. And marsupialization is meaningful to ductal cyst that cannot be enucleated completely.

Due to the fact that fisheye lens can provide super wide angles with the minimum number of cameras, field-of-view over 180 degrees, many vehicles are attempting to mount the camera system. Not only use the camera as a viewing system, but also as a camera sensor, camera calibration should be preceded, and geometrical correction on the radial distortion is needed to provide the images for the driver's assistance. In this thesis, we introduce a geometric correction technique to minimize the loss of the image data from a vehicle fish-eye lens having a field of view over $180^{\circ}$, and a asymmetric distortion. Geometric correction is a process in which a camera model with a distortion model is established, and then a corrected view is generated after camera parameters are calculated through a calibration process. First, the FOV model to imitate a asymmetric distortion configuration is used as the distortion model. Then, we need to unify the axis ratio because a horizontal view of the vehicle fish-eye lens is asymmetrically wide for the driver, and estimate the parameters by applying a non-linear optimization algorithm. Finally, we create a corrected view by a backward mapping, and provide a function to optimize the ratio for the horizontal and vertical axes. This minimizes image data loss and improves the visual perception when the input image is undistorted through a perspective projection.

Recently, plastic recycling has emerged as a social issue, and its importance is increasing. Therefore, this article reviewed the current status and the future directions of domestic plastic recycling. Plastic recycling is major economic and social problems not only in South Korea but also worldwide and is being treated as an important factor for protecting the environment and for sustainability in the next generation. In particular, China, which has been dealing with a large amount of plastic waste generated around the world, has banned importing plastic waste, therefore, other countries have faced the problem of recycling plastics in their countries. In South Korea, the landfill and incineration of the waste are becoming more difficult by the Framework Act on Resources Circulation, therefore, the recycling and reuse of plastics are a very important.

문학치료학적 관점에서 본 <심청전> 재창작 수업사례 연구

조영주 ( Cho Young-ju ) 한국고전문학교육학회 2016 고전문학과 교육 Vol.32 No.-

본 논문에서는 필자가 서울시내 A대학에서 2014년 2학기 국어국문학과 전공선택 과목인 <고전과 창작> 수업시간에 실시한 강의에 근거하여, 수업시간에 실행한 재창작 수업의 과정을 소개하고, 그 과정에서 보여주는 대학생들의 자기성찰 양상을 탐색하고자 하였다. 수업에 참여한 대학생들이 3회의 발표를 통해 만들어낸 작품을 주 분석 대상으로 삼았다. 2장에서는 고전작품 재창작을 위한 수업 진행의 과정으로서 ‘재창작 작품 선정 배경 및 기획의도 발표’, ‘원작에 대한 분석 및 재창작 사례 탐색’, ‘작품 재창작 및 메타글쓰기’에 대해 논의하였다. 3장에서는 작품 재창작 과정을 통한 대학생의 자기성찰 양상을 탐색해보았다. 학생들이 재창작하고자 하는 고전 작품을 선정하고, 분석하고, 재창작하고, 재창작한 작품에 대한 자기평가에 이르는 과정을 통해서 그들이 가지고 있는 삶에 대한 태도가 어떠한지, 문제가 있다면 그 문제를 대하는 태도와 경향성은 어떠한지 살펴보는 데 역점을 두었다. 수업에 참여한 학생들은 재창작의 대상으로 제각기 서로 다른 작품을 선택하였지만, 이번 논의에서는 <심청전>을 재창작한 두 명의 대학생을 대상으로, 그들이 창작한 작품과 자기 성찰 양상을 비교분석하였다. 그리하여 아버지와의 관계 양상에 따른 창작결과물의 특성에 대해 살펴볼 수 있었다. 고전을 활용한 보다 효과적인 재창작 수업을 위해 작품을 선정하고 보다 체계적이고 다양한 재창작 방법론에 대한 모색이 필요할 것이다. 그러나 고전을 활용한 재창작 수업은 원작의 작품서사를 활용하기 때문에 창작에 대한 부담을 줄일 수 있었고, 자기성찰의 매개가 되는 고전작품을 통해 평소 본인이 고민하는 문제에 대한 깊이 있는 탐색이 가능하다. 또한 공개적인 작품 발표를 통해 보다 객관적인 입장에서 자기서사를 탐색할 수 있고, 피드백을 통해 다른 사람의 의견을 수렴하는 것이 가능하다는 점을 확인할 수 있었다. This paper describes the procedure of recreating the classics which introduced in author’s lecture on “Classics and Creation.” The work and result of this paper is based on the activities in the Korean language and literature lecture which the author was leading at university A in Seoul in 2014. This paper aims to identify aspects of introspection that college students underwent during the procedure of recreating. The subjects for analysis were the works created by college students participating in the class through three presentations. In section 2, it is discussed three major issues regarding the process of recreating classics. One is “presentation of the background for the selection of the work to recreate and the way of implementation”. Second is “analysis of the original works and case studies on recreated works”. Third is “recreation of works and meta writing”. Those activities were conducted as part of the lecture. In section 3, it is investigated that the pattern of introspection of college students. It focused on analyzing the attitudes of the students toward life based on their selection, analysis, and recreation of classic works. Moreover, their self-assessment of the recreated works was examined as well. It is noted that the attitudes and tendency of students when faced with problems if any. While the students in the class selected diverse works for recreating, this paper compared and analyzed the works and introspective aspects of two students who recreated Simcheongjeon. Therefore, aspects of creativity could be identified based on the pattern of their recreation, which participants subtly describe the relationship with their father in recreated works. In accordance with the analysis, it is required to select more works for an effective class on recreation of classic literature and investigate a more systematic and diverse methodology for doing so. However, since the class for recreation of classic literature uses the narrative of the original work, it would reduce the burden on creation. In addition, it is possible to scrutinize in-depth problems of participant’s general issue in life by using classic literature as a medium for introspection. Moreover, it was identified that a public presentation of these works enabled exploring self-narration on more objective aspects and collecting feedback from others.

북한여성연구의 여성주의적 확장 가능성

조영주(Young-Ju Cho) 이화여자대학교 한국여성연구원 2018 여성학논집 Vol.35 No.1

이 글은 북한여성연구의 활성화의 조건과 여성주의적 확장가능성을 탐색하는 것을 목적으로 한다. 그동안 북한학과 여성학에서 북한여성연구는 제한적으로 이루어졌다. 따라서 이 글은 북한학과 여성학에서 북한여성연구가 활성화되기 위한 조건과 여성주의적 개입의 가능성을 살펴보고자 했다. 이를 위해 그동안 북한학과 여성학에서 진행되어온 북한여성연구의 궤적을 각 분야의 주요 학술지를 중심으로 살펴보고, 북한여성연구의 여성주의적 개입 또는 비개입의 맥락을 살펴보았다. 북한학에서는 2000년대 들어 북한여성연구가 상대적으로 활성화된 경향이 있고, 주로 북한의 시장화에 따른 여성 삶의 변화와 공식담론에서 나타나는 여성상에 대한 탐구를 하였다. 여성학에서는 1990년대에 북한여성연구가 활성화되었고, 2000년대 들어 간헐적으로 연구가 진행되었다. 여성학과 북한학에서 북한여성연구가 활성화된 것은 당시의 국내외 정세와 북한체제의 변화가 관련이 있었다. 그러나 전반적으로 여성학이나 북한학에서 북한여성연구는 충분히 이루어지는 못했다. 북한여성연구의 여성주의적 비/개입의 맥락들을 살펴보면 우선 북한여성 연구자의 위치성이 북한여성연구의 주제와 접근 방법에 영향을 주었고, 구조적으로는 북한학 학문공동체 내의 성별분업, 프로젝트 중심의 학문 재생산 구조, 연구자의 재생산 문제가 있었다. 이러한 한계를 넘어 북한여성연구에 대한 여성주의 접근의 활성화를 도모하기 위한 조건들로 이 글에서는 객관성과 위치성의 재구성을 통한기존 북한연구 패러다임의 전환과 여성학연구 성과의 북한여성연구 접목을 제안하였다. This article aims to explore the conditions that activate North Korean women’s research and the possibility of feminist approach to North Korean Women. Research on North Korean women has been limited to North Korean studies and women’s studies. Thus, this article intends to examine the possibility of feminist intervention in North Korean women’s studies and the conditions necessary to activate North Korean women’s research in North Korean studies and women’s studies. To this end, the history of North Korean women’s research in North Korean studies and women’s studies was examined mainly through prominent journals in the respective fields, and the context of feminist intervention or nonintervention in North Korean women was also explored. Compared to the past, in the 2000s, North Korean researchers began to research North Korean women more actively, with a focus on the image of women in public discourse and the changes in women’s life after the market economy was introduced. In the 1990s, scholars in the field of women’s studies actively researched North Korean women, but this slowed down in the 2000s. The activating of North Korean women’s research in women’s studies and North Korean studies was related to changes in the domestic and international circumstances and the North Korean system. In general, however, neither women’s studies nor North Korean studies covered North Korean women’s research very deeply. The contexts of feminist non/intervention in North Korean women’s research were as follows. The positionality of researchers of North Korean women influenced the topics and the approach to North Korean women’s research. Structually, there were gender division of labor in the academic community of North Korean studies, the constraints in project-based researches and the difficulties of reproducing researchers. To overcome such limitations and to promote the activating of the feminist approach in North Korean women’s research, this article proposed shifting the previous paradigms of North Korean studies through the reconstruction of objectivity and positionality, and integrating the research achievements of women’s studies with North Korean women’s research.

Background/Aims: Add on adefovir (ADV) to ongoing lamivudine (LAM) has been recommended as a standard therapy for the treatment of LAM resistance. In the past, switch to ADV monotherapy was suggested as an option for the treatment of LAM resistance, leading to frequent development of ADV resistance. However, ADV monotherapy has been still used in LAM-resistant patients because of low cost in Korea. The aims of this study were to evaluate the virologic response and virologic breakthrough during adding on LAM in LAM-resistant patients receiving ADV monotherapy. Methods: The study population comprised 99 patients with LAM-resistance. We divided them into 3 groups (Group 1: switch to ADV monotherapy, N=58, Group 2: add on ADV to ongoing LAM, N=25, Group 3: add on LAM to ADV monotherapy, N=16). HBV DNA levels were assessed at baseline and every 3 months during therapy. Serum HBV DNA levels were measured by bDNA assay or the COBAS TaqMan(TM) HBV test. Results: The median treatment duration for group 1, group 2, and group 3 was 42.0, 20.6, and 31.8 (18.7 mon. of ADV+13.1 mon. of LAM) months, respectively. Cumulative rate of virologic breakthrough in group 1 was 5.2%, 19.0%, and 25.9% at 12, 24, and 36 months of treatment, respectively. Virologic breakthrough was not detected in group 2 and group 3 (p=0.016, group 1 vs. group 2 or 3). In group 3, median serum HBV DNA levels were 4.22 log(10) copies/mL prior to LAM administration. Median serum HBV DNA changes from baseline (log10 copies/mL) were ?0.91, ?1.93, ?1.87 and ?1.74 at week 12, 24, 36 and 48, respectively. Conclusions: Later add on LAM to ADV monotherapy prevented the development of ADV resistance in patients with LAM resistance effectively, comparable to ADV add on to continuing LAM therapy.
