윤명희(Myunghee Yoon) 한국간담췌외과학회 2008 한국간담췌외과학회지 Vol.12 No.1

Purpose: To overcome donor shortage, reduced-size liver transplantation, spilt-liver transplantation and partial liver transplantation from living donors for children are frequently used all over the world. Despite the difficulties of a adequate volume reduction and the age difference between donor and the recipient, all these techniques also share the problem of size mismatch between the vessels of the adult liver and those of the pediatric recipient. portal vein reconstruction in a crucial factor for a successful transplantation because it allows blood flow to the liver graft, which ends the ischemic period for the graft, as well as the anhepatic period for the recipient. Methods: In GroupⅠ(n=10, no growth factor), a partial liver of Sprague-Dqwley(SD) rat was transplanted heterotopically, via microsurgical technique, to a SD rat with performing end-to-end portal vein anastomosis without applying growth factor to the suture of the portal vein. In GroupⅡ(n=10, 50-60% growth factor), a partial liver of a SD rat was trnasplanted heterotopically to a SD rat, via microsurgical technique, with applying growth factor to 50-60% of the diameter of the portal vein. In GroupⅢ(n=10, 80-100% growth factor), the portal vein was anastomosed, via microsurgical technique, with using growth factor to 80-100% of the diameter of the portal vein. Results: In GroupⅡ, only one case has portal vein stenosis on the postoperative 14th day following portal vein anastomosis with growth factor. In GroupⅠ, 3 cases showed portal vein stenosis on the postoperative 7th day, and 5 cases showed portal vein thrombosis on the postoperative 14th day. In GroupⅢ, 6 cases died due to bleeding after declamping of the portal vein anastomosis with using 80-100% growth factor on the diameter and 1 case has portal vein thrombosis on the postoperative 14th day. Conclusion: Several surgical factors might have an important role in preventing vascular stenosis and thrombosis, and especially when transplanting a technical-variant liver graft like a difference in caliber between the donor and recipient vessels, the growth-factor suture technique having 50-60% of one diameter might be helpful because it allows for expansion along the suture line and it also prevents a purse-string effect.

매개된 광장과 청소년의 재발명: 2016년 촛불집회의 청소년참여 레퍼토리 분석을 중심으로

윤명희(MyungHee Yoon) 한국문화사회학회 2020 문화와 사회 Vol.28 No.1

온•오프라인이 연결된 매개된 광장에서의 청소년참여는 청소년 정체성의 지속적인 재발명 과정이며 이는 청소년참여 레퍼토리를 통해 구체적으로 드러난다. 2016년 촛불집회과정에서 활용된 청소년의 참여 레퍼토리에서 청소년정체성은 고정된 세대 특성으로 환원되지 않으며 상황맥락화된 조건 및 사회적 타자와의 관계 속에서 재/형성되는 과정으로 나타난다. 매개된 광장에서의 청소년참여는 비청소년과의 함께하기는 물론 구별짓기 역시 동시에 수행되는 복합적 과정이다. 함께하기의 과정에서 청소년들은 비청소년과 함께 ‘분노하는 주권자’로서 참여하며 교복을 입고 사회적 목소리를 내는 ‘친숙한 이방인’이라는 모호한 정체성을 전시한다. ‘거부된 참정권’의 상황이 전개되면서 청소년의 재발명 과정은 비청소년과의 구별짓기라는 특징을 보다 뚜렷이 보이는데, 이 과정에서 청소년 정체성은 비청소년과 ‘동등하면서도 다른’ 사회적 존재로서 강조된다. Youth participation in the mediated squares connected online and offline is a process of continuous reinvention of youth identities, which can be examined in detail through repertoires of youth participation. In repertoires of youth participation practiced in 2016 candlelight rallies, youth identity is not reduced to a fixed generational characteristic, but appears as a process of re-formation in contextualized conditions and relationships with social others. Youth participation in mediated squares is a complex process of not only joining but also distinguishing with non-youth. Along with non-youth, youth perform as an “angered sovereign,” but they also display the ambiguous distinction of “familiar stranger” who wear school uniforms and make social voices. The reinvention of youth in the situation of a denied suffrage is more characterized by a distinction from non-youth, and youth identity is emphasized as an “equal but different” social beings from a non-youth.

디지털 창의노동: 여성 게임개발자 사례

윤명희(MyungHee Yoon) 한국문화사회학회 2021 문화와 사회 Vol.29 No.1

이 연구는 여성 게임개발자 사례에 대한 질적 연구를 통해 디지털 창의노동의 양가적이고 복합적인 현실을 논의하고 있다. 우선, 여성 게임개발자들의 성장기와 청년기에 놀이나 여가로 경험한 게임하기는 디지털친화적인 세대의 보편적 특징과 함께, 게임하는 여성이 잘 보이지 않는 상황이라는 성별로 다르게 경험되는 세대 내부의 차이 역시 보여준다. 둘째, 여성이 보이지 않는 상황은 여성 게임 개발자들의 ‘게임 만들기’ 경험에서도 지속되며 이는 창조적 역할의 성별화와 비명시적이고 미묘한 배제관행과 관련되어 있다. 셋째, 여성 개발자들의 창의노동 주체성은 합리성, 창의적 열정, 평등주의과 같은 특성 일반을 보여주는 한편, 한층 강화된 자기착취라는 상이한 인식과 노동경험으로도 나타난다. 마지막으로 임신·출산 이후 여성게임개발자에게 창의노동 정체성은 ‘낮아지는 기술적 능력’을 설명하는 근거가 되는 한편, 성차별주의와 교차되면서 창의조직 내 여성에 대한 사회적 폐쇄를 정당화하는 데 활용되는 경향을 보인다. This study discusses the ambivalent and complex reality of digital creative labor through qualitative research on the case of women game developers. First, playing games experienced by women game developers in their growth and youth shows the universal characteristics of the digital-friendly generation, while also showing the differences of gendered experiences within the generation such as the situation where female gamers are barely visible. Second, the situation in which women are invisible also persists in the experience of game making of women game developers, which is related to the gendering of creative roles and the practice of non-explicit and subtle exclusion. Third, the creative labor identity of women game developers, along with characteristics such as rationality, creative passion, and equality, also appears in different perceptions and labor experiences of more enhanced self-exploitation. Finally, after pregnancy and childbirth of women game developers, creative labor identity serves as a basis for explaining their "lowering technological capabilities" and it tends to be used in creative organizations to justify social closure to women game developers, intersecting with gender discrimination.

백서 신장이식 후 만성 동종이식 신병증 예방을 위한 저농도 Carbon Monoxide 흡입 치료

윤명희(Myunghee Yoon) 대한외과학회 2008 Annals of Surgical Treatment and Research(ASRT) Vol.74 No.5

Purpose: Carbon monoxide (CO), a product of heme catalysis by heme oxygenase (HO-1, HO-2, HO-3), induces cytoprotection against ischemia/reperfusion (I/R) injury in a variety of organs such as the heart, lungs, kidneys, and liver. Ⅰ examined whether CO would prevent chronic allograft nephropathy (CAN) associated with renal transplantation in rats. Methods: Kidneys from male Fisher rats were perfused and harvested for transplantation. Lewis rats were used as recipients. After reperfusion of the implanted kidney, the recipient’s remaining kidney was removed promptly. Recipients were then immediately treated with the indicated regimen of CO in a Plexiglas exposure chamber. At 90 days after transplantation, the animals were sacrificed for graft histopathology, serum creatinine, and blood urea nitrogen (BUN) as markers of kidney function. Results: CAN in rats was achieved using a model of Fisher-to-Lewis transplants and evaluating kidney function over the 90 days following transplantation. CO administered at 100 ppm for 1 hr/day for 7 days prevented CAN at 90 days post-transplant. CO also decreased histopathological alterations, including leukocyte infiltration and cell death. Conclusion: These data expand our understanding of the protective effects of low-dose CO inhalation in preventing the development of chronic fibro-inflammatory changes associated with chronic allograft nephropathy and allow us to devise methods for improving long-term renal allograft function.

디지털위험의 역동성

윤명희(Myunghee Yoon) 한국문화사회학회 2015 문화와 사회 Vol.19 No.-

이 연구는 ‘이해없는 사용’의 일상화가 매개하는 디지털 위험의 역동성을 위험 일반 및 디지털위험에 관한 기존의 담론을 통해 살펴보고 있다. 먼저, 이 연구는 ‘위험’ 일반에 대한 논의들을 ‘사회의 위험’ 시각과 ‘위험의 사회’ 시각으로 나눈다. ‘사회의 위험’이 ‘위험’을 현대세계가 처한 사회적 위험의 차원으로 접근한다면, ‘위험의 사회’는 ‘위험’을 사회적 위험인지와 위험감수성, 커뮤니케이션을 통해 구성된 위험으로 다룬다. 전자가 ‘위험’을 위험의 객관적 수위를 가진 실체적 사건으로 제시한다면, 후자는 ‘위험이 위험이 되는 과정, 즉 실재화 과정에 좀더 초점을 두는 구성주의적 시각을 띠고 있다. 다음으로, 이러한 두 시각에 대한 논의를 바탕으로 한국의 위험 일반 및 디지털 위험과 관련된 연구 경향들을 검토하고 있다. 이를 통해 정보위험‧빅데이터위험을 강조하는 한국의 디지털 위험 연구가 실체적 위험론에 상당부분 치중하여 ’이해없는 디지털 사용‘과 관 련된 역동적 차원들을 충분히 포착하고 있지 못하다는 점을 비판적으로 논의하고 있다. This study discusses the dynamics of digital risks mediated by routinization of digital uses without understanding through critically examining the existing researches on risks. Perspectives on risks in this study are divided into "risk of society" and "society of risk". Risk from the perspective of a "risk of society" is considered to be objective and social risks. In contrast, risk from the perspective of "society of risk" is considered to be social construction associated with risk perception, risk sensitivity and communication. This study points out that the problems found in existing studies in Korea on information risk and big data risk is that it does not fully capture the dynamics related to digital uses without understanding.

디지털 연결사회에서 사생활은 소멸하는가

윤명희(MyungHee Yoon) 한국문화사회학회 2017 문화와 사회 Vol.24 No.-

이 연구는 디지털 연결사회에서 두드러지는 사생활 경계의 유동성을 사생활의 소멸이 아니라 네트워크화된 사생활의 경계화 과정으로 접근하고 이를 익명성과 투명성 사이를 오가는 선별적 자기 전시를 통해 논의하고 있다. 주요 연구내용을 정리하면 다음과 같다. 첫째, 이 연구는 근대 이후 사생활이 숨겨지고 은폐되어야 할 영역에서 벗어나 사회적 의미를 획득하고, ‘연결된 집’이라는 내·외부의 경계가 유동적인 영역으로 변화되어온 과정에 대해 논의하고 있다. 둘째, 이 연구는 매체 및 소셜네트워크의 일상화에 따라 사생활 경계의 유동성과 함께 이에 대응하는 수행적 차원 역시 증대하고 있다는 데 주목하고 이를 네트워크화 된 사생활의 경계화 과정으로 논의하고 있다. 셋째, 네트워크화된 사생활의 경계화는 지향화된 자기를 선별적으로 전시하는 상호작용 과정을 통해 이뤄지는데, 이 선별적 자기 전시의 과정에서 나타나는 자기의 과시와 기만, 은폐는 과도함이나 속임수, 은둔이 아니라 자기대면적이면서도 협력적인 수행이라는 의미를 띠고 있다. This study discusses the fluidity of the privacy boundary, which is prominent in the mediated reality, not as the disappearance of the private life, but as a process of boundarization of the networked privacy, and through selective self-exhibition between the anonymity and the transparency. The main research contents are summarized as follows. First, this study focuses on the fact that the privacy in modern society is deviated from the perception that it is a hidden and concealed domain, and acquires important social meanings. This also discusses the process in which the privacy in mediated reality has been transformed into a dynamic domain that is difficult to distinguish between internal and external boundaries. Second, this study focuses on the increasing corresponding performativity as well as fluidity of privacy boundaries in the strengthened mediated reality, and discusses this as a process of boundarization of the networked privacy. Third, the boundarization of the networked privacy is constructed through the interactive process of selectively presenting intended self such as what he or she want to be seen. The self-display, self-deception and self-concealment that appear in this selective self-exhibition process are not excessive, cheating, and seclusion, but reflexive and cooperative performance.

담낭암 절제 수술 후 종양 침범 깊이와 임파선 전이에 따른 생존율 분석

문형환(Hyung Hwan Moon),윤명희(Myunghee Yoon) 한국간담췌외과학회 2008 한국간담췌외과학회지 Vol.12 No.2

Purpose: Carcinoma of the gallbladder is an aggressive, late-symptomatic disease and most patients are treated at an advanced stage, and these patients have a poor prognosis. During recent years, extended operations that combine a resection of the liver with wide lymph node dissection have improved the long-term survival. The aim of this study is to evaluate the surgical outcome for gallbladder carcinoma based on the presence of lymph node metastasis and the depth of the primary tumor invasion. Methods: A retrospective analysis was done on 68 patients who underwent a surgical resection of gallbladder carcinoma from 1997 to 2004. The factors that influenced the 5-year survival were examined. Results: The overall 5-year survival rate was 49.6%. The lymph node metastasis rate was 40.0% in T2 disease and 61.1% in T3/T4 disease. The 5-year survival rate (5-YSR) for T2 disease was 52.1% for the patients who underwent cholecystectomy with lymph node dissection and hepatic resection, and it was 51.2% for the patients who underwent only simple cholecystectomy. The 5-YSR for T3/T4 disease was 33.3% for the patients who underwent extended cholecystectomy, and it was 12.9% for the palliative cholecystectomy patients. Conclusion: The role of radical surgery seems to be limited for patients with more extensive tumor invasion or lymph node metastasis.
