      • Current Status of Heart Transplantation and Left Ventricular Assist Device: Major Changes in the Last Decade

        이숙진,홍석근 한양대학교 의과대학 2014 Hanyang Medical Reviews Vol.34 No.4

        Heart transplantation is the last treatment option in refractory end stage heart failure, which can prolong survival. The number of heart transplantations has increased and the survival rate has improved during the last few decades which was contributed by advanced understanding of immunologic mechanism of rejection, pharmaceutical development and clinical management of donors and recipients. However, only a fraction of patients can be offered to transplantation due to shortage of donor heart and many patients suffer high mortality while waiting. Meanwhile, technical advancement of mechanical assist device in recent years enabled long term implantable left ventricular assist devices (LVAD) to bridge the patients with high mortality in the waiting list to transplantation and to assist as a long term destination therapy for patients who are not eligible for transplantation. Development of solid phase assay increased the sensitivity and the specificity of detection of anti-human leukocyte antigen (HLA) antibodies in the recipient. It enabled identifying unacceptable HLA antigens, acquire calculated Panel Reactive Antibodies and perform virtual cross match that can enhance the efficacy of donor allocation system to decrease the waiting time, obviate prospective cross match to decrease ischemic time and to assess the risk of rejection in presensitized patients. Antibody mediated rejection is a challenging entity in diagnosis and management. However, standardized classification of histology and immunology of endomyocardial biopsies was made recently and immunotherapy is moving toward targeted therapies directed at antibody production and function. This review focuses on those major changes in the heart transplantation field in the last decade.

        동구 사회주의 국가의 여성정책

        이숙진 이화여대 한국여성연구소 1990 여성학논집 Vol.7 No.-

        The purpose of this paper is to study the relation between socialist state and women through the state policy toward women in Eastern Europe. It helps us to understand the socialist patriarchy and to grasp the condition of women's liberation in Eastern Europe. Most of socialist societies have officially defined the sexual equality on their program and law. But we have to reexamine the definition whether it includes sexual equality and women's liberation ideology or how it has the effectiveness to change the woman's condition. In employment policy, Eastern Europe has supported the entrance of women's wage labor. But the integrating women into the workforce is not a sufficient condition for women's emancipation. Women workers in Eastern Europe are concentrated in female industries such as textile, garment and electrical assembly, and women earn on the average 70 percent of what men earn. And these countries seem to he not intended to resolve these problems. Childcare policy is essential in socialist countries if women and men are to have an equal opportunity to participate in the labor force. Despite the drop of birth rate, it is a fact that childcare facilities are generally increase and the isolation of women in home are institutionally supplemented. But the childcare policy of these countries is a consistent traditional sexual identity which assumes that women will be responsible for children. In the system of maternity protection, the primary method of birth control in Easern Europe has depended on abortion. And the state has actively intervened in pregnancy-dilivery process. Easern Europe has placed the women's pregancy under the protection of the state. It has to be evaluated quite positively in better health for both mother and child. And it has involved social evaluation about women's pregnancy. But there is the question of women's control ability over reproduction. It has to be discussed the right of women themselves over reproductive capacity. The existence of social service and the law of maternity protection in Eastern Europe makes the position of women somewhat easier. But it has to be considered that the material barriers and the general standard of living and intention of the state policy have affects on the interests of women. Eastern Europe emphasized the importance of women's paid labor and the state's obligation to free women from domesticity and childrearing. Therefore these countries seem to support women increasing social and economic independence. Nevertheless, women in Eastern Europe remain oppressed as many ways as women in the West. It has provided that socialist countries have not completely spoken of women's interests today. Women's interests and state interests are complicated in socialism.

      • 發育鷄肝組織의 Cholesterol Esterifying Enzyme에 關한 硏究

        李淑眞,李根培 우석대학교 의과대학 1970 우석의대잡지 Vol.7 No.2

        The cholesterol esterifying enzyme activity in developing chick liver from 14th day of incubation to hatching and adult hen has been studied. Chick livers from 14th day embryo and post-hatching were homogenized with 0.154 M phosphate buffer(pH 6.5) and incubated with oleate, sodium taurocholate, egg albumin and merthiolate for appropriated duration, in a shaker at 37℃, and then lipids were extracted by adding chloroform-methanol mixture. The resutls obtained are as follows: 1. The activity of this enzyme was demonstrated in the liver at 14th day of incubation. 2. The liver of 14th day of incubation contained 4.0㎎ free cholesterol /g wet tissue. Similar values for the concentration of free cholesterol in the liver were found through the later phase of development and post natal period, except the livers of 21st day of incubation and of 1st day after hatching in which the free cholesterol contents have been shown to be 10.7㎎ and 40.5㎎/g wet tissue. respectively. 3. Cholesterol esterifying capacity of liver homogenate from 141th day of incubation has been shown to be approximately 9%, and was followed by a gradual increase during further incubation period. Immediately after hatching, the cholesterol esterifying capacity reached a maximum, (approx. 16%), then showed a slight decrease and reached the adult level. At 60th day after hatching the esterifying capacity was approximately. 4. The significance of activity of liver cholesterol esterifying enzyme is discussed in connection with the cholesterol ester concentration in developing chick liver.

        WiBro시스템에서 주기적 레인징 코드를 이용한 다중 레벨 Keep - Alive 알고리즘

        이숙진,김환우,Lee, Sook-Jin,Kim, Whan-Woo 한국통신학회 2007 韓國通信學會論文誌 Vol.32 No.6a

        최근 초고속의 무선데이터 통신을 지원하기 위한 시스템으로 WiBro (Wireless Broadband) 시스템이 대두 되고있다. 본 논문은 WiBro시스템의 한 셀에서 서비스 중인 단말기의 비정상 상태를 점검하는 다중레벨 keep-alive 방법(MLKA : Multi-Level Keep Alive) 방법을 제안하고 있다. 본 논문에서 제안하는 MLKA방법은 WiBro 시스템에서 주기적인 레인징 코드들을 그룹화 하여 단말의 위치에 따라 시간 오차와 전력 오차를 조정하기 위해서 사용하는 주기적인 레인징 기능을 이용한다. 본 논문에서 제안하는 MLKA 알고리즘은 단말의 비정상 상태를 점검하기 위해서 필요한 keep-alive 메시지 사용을 감소 시킨다. 본 논문에서는 제안된 알고리즘의 우수성을 검증하기 위해서 이론적인 수학적 접근 방법과 시뮬레이션 검증 방법을 사용 하였고, 시뮬레이션 결과로부터 기존의 메시지 기반 keep-alive 방법보다 keep-alive 메시지 사용을 줄일 수 있다. 그러므로 본 논문에서 제안하는 MLKA 알고리즘은 제어 메시지 사용을 감소 시키므로 WiBro 시스템의 트래픽 성능을 증가 시킨다. In this paper, we propose a MLKA (Multi-Level Keep-Alive) algorithm based on PRCG (Periodic In this paper, we propose a MLKA (Multi-Level Keep-Alive) algorithm based on PRCG (Periodic Ranging Code Group), in which periodic ranging codes are divided into groups. The AP (Access Point) performs this algorithm when a periodic ranging code arrives at the AP in a WiBro (Wireless Broadband Internet) system. In order to increase the traffic radio bandwidth resource efficiency in this system, we propose the multi-level keep-alive algorithm for finding abnormal AT (Access Terminal). From simulation results, it is verified our proposed MLKA algorithm based on PRCG can provide higher traffic radio resource efficiency compared to message-driven keep-alive algorithms.

        여성정치세력화와 여성대통령 만들기 : 박근혜정부에 대한 기독교 여성윤리학적 비평

        이숙진 한국기독교사회윤리학회 2013 기독교사회윤리 Vol.26 No.-

        Park Geun-hye, before the 18th president election of Korea, was a veteran politician who got various names such as “star politician,” “a queen of election,” “the only one candidate for President.” Female elites seeking for feminist politics were not assured that she could be a stepping stone or an obstacle for the political empowerment of women in Korea. Park Geun-hye has two images, “a daughter of Park Jung-hee, the late former President” and “a supporter of Yushin regime as dictatorship.” While the first helped her entering politics in the general election of 1998, the second seemed to become a leg iron for her presidential candidate in 2012. Surprisingly she, however, succeeded in becoming a president. Who supported Park, naming her as a representative of women? This question is related to the controversy among women elites over support for Park as an female politician in the past ten years. In the perspective of christian feminist ethics, this paper tried to contribute to the task of making gender-equality society through the creative conflicts between Park regime and progressive feminist camp 18대 대선 이전의 박근혜는 ‘스타 정치인’, ‘선거의 여왕’, ‘독보적인 대통령 후보’라는 타이틀을 교체해 온 노련한 정치인이다. 여성정치인으로서는 보기 드물게 정치적 기반을 넓게 구축한 그는, 여성정치를 기획하는 여성엘리트들에게는, 여성정치세력화의 디딤돌이 될지 걸림돌이 될지 늘 의문거리였다. 설령 여성에게 디딤돌이 된다 할지라도 그와 연대할 것인지 말 것인지에 대해서도 여성엘리트 진영 내에서는 의견이 분분했다. 그의 과거사 이력 때문이다. 박근혜에게 ‘박정희의 딸’ 혹은 ‘유신의 조력자’라는 표상은 그의 정치 입문(1998)을 도운 ‘날개’였지만, 대선(2012)에 도전하는 그에게는 절대 풀릴 것 같지 않은 ‘족쇄’였다. 그런데 어느 순간 그 족쇄에서 빠져나와 그는 ‘여성’대통령이라는 날개를 달았다. 누가 그에게 여성대표성의 날개를 달아주었는가?라는 물음은 여성정치세력화를 추진하던 여성들이 지난 10년 동안 정치인 박근혜에 대한 지지여부를 두고 벌인 논쟁을 규명하는 작업과 맞닿아있다. 이러한 물음에서 출발한 이 글은 18대 박근혜정부와 진보적 여성진영이 창조적인 갈등을 통해 성평등의 사회를 추구하는데 있어, 한국기독교 여성윤리학이 기여할 수 있는 점을 모색하는 것이 목적이다.
