박승일,김용진,Park, Seung-Il,Kim, Yong-Jin 대한흉부심장혈관외과학회 1990 Journal of Chest Surgery (J Chest Surg) Vol.23 No.1

The results of conventional operative resection of diffuse subaortic stenosis[tunnel subaortic stenosis] have been less than satisfactory. We have performed modified Konno operation to enlarge the outflow tract of both ventricle with a patch in three patients with diffuse tunnel subaortic stenosis in the department of Thoracic and Cardiovascular Surgery, Seoul National University Children`s Hospital. Preoperative left ventricular aortic pressure gradients were 135 mmHg, 50 mmHg, 80 mmHg respectively in these patients. After right ventriculotomy, the septotomy was done and extended beyond the limit of the stenosis and fibrous and/or muscular tissue was removed from each edge of septal incision. After adequate widening of the tunnel subaortic stenosis with various patches, right ventricle was closed primarily or with prosthetic patches successfully. One patient who was diagnosed as complete atrioventricular septal defect had complete AV block preoperatively and was implanted permanent pacemaker, and others who were sinus rhythm preoperatively have no serious postoperative rhythm disturbance. One patient developed mild postoperative aortic insufficiency and one who had preoperative aortic insufficiency has still same grade of aortic insufficiency after operation. All had good postoperative hemodynamics without any postoperative residual pressure gradient.

Severe hemodynamic dysfunction may follow after the closure of the median sternotomy in patients with myocardial edema, cardiac dilatation, and severe postoperative bleeding. In extreme cases, myocardial edema may be so severe that cardiac function is compromised merely by the edges of the open sternum touching the heart. Sternotomy remained open and delayed sternal closure is already described adjunct in complicated cardiac operations. We experi nced a case of delayed sternal closure after 16 hours of CABG using synthes DCP wide plate in a 54-year old obese female patient. Our experience conims that delayed sternal closure Is an effective at simple means of dealing with severe myocardial edema so we report this case with literature review.

변형 Blalock-Taussig 수술법이 폐동맥성장에 미치는 영향

Modified Blalock-Taussig operation remains the standard technique of systemic-to-pulmonary artery shunt in patients of congenital heart disease with decreased pulmonary blood flow. We reviewed the 41 patients who had been performed modified Blalock-Taussig operation from March 1985 to Feb. 1988, and angiographically measured pulmonary artery size before and after shunt, and calculated pulmonary artery index [PAI] and ratio of left and right pulmonary artery to descending aorta[[LPA+RPA]/dAo]. The mean duration of palliation after shunt operation was 624 days and mean age of the patient at shunt operation was 3.59 years. Mean PAI increased significantly from 131.15*67.11 mm2/M2 preoperatively to 232.70*84.46 mm2/M2 postoperatively. Mean ratio of right and left pulmonary artery to descending aorta also increased significantly from 1.48*0.40 preoperatively to 1.92*0.50 postoperatively. All patients manifested clinical improvement; there was mean decrease in hematocrit of 8.95%, mean increase in arterial oxygen saturation of 11.08%. Pulmonary arterial growth was not influenced by age at operation, initial pulmonary artery size, or graft size, but significantly influenced by antegrade flow. The patients who have some antegrade flow were in more increase of PAI. There were no linear correlation between change of PAI, change of [[LPA+RPA]/dAo], SaO2, and duration. But, according to Scatterplot between change of PAI and duration, some complex correlation was suggested and mean PAI was decreased after 2-year palliation. We concluded that modified Blalock-Taussig operation is excellent palliative surgery for pulmonary artery growth especially on the patient who have some antegrade flow, and the proper duration of palliation was about 2 years.

선천성 심장기형 환자에서 조기술후 심실 전부하 용적과 심박출량의 상호 관계 및 혈역학적 변화 분석

박승일,김응중,김용진,Park, Seung-Il,Kim, Eung-Jung,Kim, Yong-Jin 대한흉부심장혈관외과학회 1990 Journal of Chest Surgery (J Chest Surg) Vol.23 No.1

Postoperative cardiac performance of cyanotic congenital heart disease is somewhat different from that of other cardiac diseases. For the evaluation of postoperative cardiac performance in the cyanotic congenital heart disease we measured cardiac output by thermodilution technique at 1, 4, 8, 12, 16, 20, 24, 36, 48 postoperative hours in 14 patients operated from Feb. 1989 to Nov. 1989 in The Department of Thoracic and Cardiovascular Surgery, Seoul National University Children`s Hospital. At the same time, we checked left atrial pressure [LAP], central venous pressure [CUP], and mixed venous oxygen saturation [SvO2] to detect correlation between them. Immediate postoperative cardiac index was 3.585 $\pm$ 0.945 L/min/m2, and it decreased maximally to 3.322$\pm$1.007 L/min/m2 at postoperative 16 hours. After then it increased and stabilized from 36 hours after operation, and its value was 4.426$\pm$1.358 L/min/m2. There were no correlations between cardiac index and left atrial pressure or central venous pressure. Between mixed venous oxygen saturation and cardiac index, there was no correlation in the early postoperative period but after postoperative 16 hours, there was significant correlation between them and correlation coefficients were 0.573 [16hrs], 0.743 [20hrs], 0.436 [24hrs], 0.560 [36hrs], 0.636 [48hrs], respectively. From these results, we concluded that in the corrective surgery of cyanotic congenital heart disease, cardiac performance was depressed in the early postoperative period. It improved from postoperative 16 hours, and stabilized from 36 hours after operation. During early postoperative period, mixed venous oxygen saturation should not be used as a predictor of cardiac performance but it could be used as a predictor of cardiac performance from 16 hours after operation.

Pulmonary aspergilloma resulting from colonization of Aspergillus fumigatus is potentially life-threatening disease due to massive hemoptysis. Between August 1990 and November 1993, twelve patients were operated for the treatment of pulmonary aspergilloma. The mean age was 38.8 years. All patients had underlying cavitary lung disease, and the tuberculosis is the most common cause. Ten patients have experienced hemoptysis, but the clinical presentation of hemoptysis at the time of operation was mostly intermittent and scanty. Operative procedures were segmentectomy in 1 patient, lobectomy in 8, pneumonectomy in 2, and pleuropneumonectomy in 1. There were three complications, bronchopleural fistula in one patient and prolonged air leak in 2. There was no postoperative death. Conclusively, our results suggest that established aspergilloma associated with tuberculosis or other cavitary lesions should undergo early elective pulmonary resection, even though it has only minimal hemoptysis.

폭력의 동학과 국가의 탄생 영화 〈매드맥스: 분노의 도로〉를 중심으로

박승일(Seung Il Park) 사단법인 언론과 사회 2021 언론과 사회 Vol.29 No.1

이 글은 〈매드맥스〉라는 영화적 재현/표상(representation)으로부터 폭력의 동학이라는 쟁점을 추출하고, 이 운동 가운데 과연 무엇이 국가를 만들어내고 또 유지시켜 가는지, 더 나아가 그렇게 탄생한 국가는 어떻게 극복할 수 있는지 등 폭력과 국가 사이의 관계를 묻고 탐구해 보는 데 그 목적이 있다. 질문은 크게 세 가지이다. 첫째, 국가는 어떻게 탄생하는가. 영화 <매드맥스>는 국가가 사라진 종말의 세계 가운데 어떻게 폭력의 운동과 함께 국가가 ‘다시’ 출현하게 되는지를 보여준다는 점에서, 국가가 어떻게 만들어지고 그 최소단위란 무엇인지를 구체적으로 사유하기에 적합하다. 둘째, 국가는 어떻게 재생산되는가. 이 영화는 특정한 인간 집단이 어떻게 폭력의 독점을 통해 부를 사유화하고 다시 그 부를 통해 폭력을 강화해 나가는지, 다시 말해 어떻게 국가의 질서를 재생산해 나가는지를 영화적 서사 곳곳에 담아내고 있다. 셋째, 국가는 어떻게 극복할 수 있는가. 영화는 사령관 퓨리오사가 임모탄 조를 죽이고 시타델을 점령하는 것으로 끝이 난다. 심지어 영화는 민중에게 권력을 돌려주는 듯한 제스처를 취하기까지 한다. 그렇다면 이로써 국가는 극복 또는 폐지된 것인가. 이 글은 영화 〈매드맥스〉에 대한 분석 및 그와 관련된 이론적 독해를 통해 국가의 탄생과 재생산, 극복의 (불)가능성을 보다 구체적으로 탐색해 나갈 것이다. 국가를 국가이게 만드는 근본 조건, 곧 폭력의 독점이라는 은폐된 얼굴을 정직하게 마주할 때에야 그 폭력을 어떻게 제어하고 통제할 것인가에 대한 질문이 가능해진다. The purpose of this article is to find the issue of dynamics of violence from the cinematic representation of Mad Max and discuss the relationship between violence and state, such as what creates and reproduces the state and how it can be overcome. There are three main questions. First, how is a state made? The movie Mad Max shows how the state reappears in the world of the end. Therefore, this movie makes us think about how a state is made and what its conditions are. Second, how is the state reproduced? The movie shows how a certain human group privatizes wealth through the monopoly of violence and strengthen violence through it again, in other words, how to reproduce the order of the state. Third, how can the state overcome? The movie ends with Commander Furiosa killing Immortan Joe and taking the Citadel. The movie even makes a gesture that seems to give back power to the people. If so, has the state been overcome or abolished? This article will discuss specifically the birth, reproduction, and overcoming of the state through analysis of the film Mad Max and its related theoretical reading. Only when we face the hidden face of the fundamental condition of creating a state, the monopoly of violence, can we question how to control the violence.

인터넷과 환경관리권력

박승일(Seung Il Park) 한국언론학회 2018 커뮤니케이션 이론 Vol.14 No.3

컴퓨터에서 무선인터넷과 스마트폰을 거쳐 빅데이터와 사물인터넷에 이르기까지, 1980년대부터 시작된 매개적 환경 구성은 현대에 이르러 점차 그 존재를 의식할 수 없을 만큼 일상적이고 자연스러운 배경을 이루고 있다. 무선인터넷과 스마트폰의 일상화가 상시적이고 잠재적인 매개 환경을 열어젖혔다면, 클라우드는 사용자의 데이터를 자동으로 저장․처리․활용할 수 있는 투명성의 환경을 구축했고, 빅데이터는 집적된 데이터를 바탕으로 현재의 경향성을 파악하고 미래를 예측 및 통제할 수 있는 환경을, 그리고 사물인터넷은 사물들 스스로 우연성의 요소들을 제어하고 조절할 수 있는 환경을 만들어가고 있다. 실로 매개적 환경의 일상화이자 편재화이며, 그러한 환경에의 불가피성이다. 여기서 쟁점은 인터넷을 둘러싼 환경 자체가 신자유주의 통치 전략의 중심에 놓이게 되었다는 것이며, 그럼으로써 매개 환경의 최적화를 통한 통치의 자동화가 일상적인 동력을 얻게 되었다는 것이다. 이 글은 이처럼 다양한 기술들이 만들어내는 매개적 환경 구성과 이를 통한 관리 및 통제의 메커니즘을 특유한 권력의 효과 및 이와 결부된 합리성의 체계로 이해하고자 했다. 그리고 이러한 작동 메커니즘을 개념 안에 담아 ‘환경관리권력’이라고 명명하고자 했다. 일상을 둘러싼 현대적 매개 환경은 개별 주체의 내면에 작동하던 권력의 주체화/예속화 과정과는 달리, 단지 환경의 관리와 통제를 통해 그 환경에 속한 인구 일반의 사고와 행동을 특정한 방향으로 이끌어낸다는 점에서 더 없이 효과적인 권력 작용이라 할 수 있다. 매개 안에 있음의 환경 속에서 점차 주체의 자리와 역할이 자동화된 데이터 알고리즘에 의해 대체되고 있는 현실은, 결국 권력의 현실적인 작동 메커니즘이 그러한 형태와 방향으로 사회의 변화를 이끌어내고 있음을 방증하는 것이라 하겠다. From the 1980s, mediating configuration has been constructed along with the emergence and development of the computer, the wireless internet, the smart phone, the Big Data, and the Internet of Things. The mediating environment has become the background of our everyday life, so that we cannot even aware of its existence. If the everyday using of the wireless Internet and smartphones opened the potentiality of the intermediate environments, the cloud has created a transparent environment for automatically storing, processing and utilizing users" data. The Big Data produces the environment in which the current tendency can be grasped, and the future can be predicted and controlled, based on accumulated data. The Internet of things is making an environment in which things can regulate and control contingency by themselves. Indeed, it is the everyday normalization of the mediating environment, and it is the inevitability of such an environment. The issue here is that the environment surrounding the Internet itself is placed at the center of neoliberal government strategies, so that the automation of government through the optimization of the mediating environment has gained everyday power. The purpose of this article is to understand the mechanisms of the management and control through the mediating configuration that these various technologies produce as a effect of distinctive power and its associated system of rationality. This paper conceptualizes the operating mechanism as ‘environment power’. Contrary to the process of subjectification of power, which operates within the interior of individual subject, the contemporary mediating environment surrounding daily life most effectively operates power by leading the thinking and behavior of general population who belong to the environment in a certain direction, through the regulation and control of environment. The fact that the place and role of the subject are gradually replaced by the automated data algorithm in the context of the ‘being-in-mediation’ tells that the actual operating mechanism of power leads to the change of the society in such form and direction.

권력과 저항 : 파레시아와 대항인도, 그리고 방법으로서의 코딩 교육

박승일(Seung Il Park) 사단법인 언론과 사회 2020 언론과 사회 Vol.28 No.4

이 글은 푸코가 마주했던 권력과 저항의 아포리아를 따라가면서 그것을 현재성의 평면에 위치시켜 새롭게 읽어내는 데 그 목적이 있다. 논의의 방향은 크게 두 곳을 향하지만, 다시 한곳으로 모인다. 하나는 푸코의 논의를 따라가면서 권력과 저항의 관계에 대한 복잡한 사유와 질문, 그리고 그 가운데의 모순과 비판 등을 검토해 나가는 것이다. 이 글에서는 규율권력에서 출발해 생명권력과 통치성을 간략하게 살펴본 뒤, 이 권력(들)에 대해 푸코가 제안한 저항의 가능성과 그러한 전략의 타당성을 비판적으로 고찰해 보고자 한다. 다른 하나는, 이처럼 추상적이고 이론적인 논의를 인터넷 시대 이후의 권력과 이에 대한 저항이라는 현재적인 문제설정으로, 그러니까 지금ᐨ여기의 문제이자 우리 자신의 질문으로 확장해 나가는 것이다. 인터넷 이후의 권력이 이전과는 다른 고유한 테크닉, 메커니즘, 전략을 통해 그만큼 촘촘하고 정교한 권력의 자장을 만들어내고 있다면, 이 가운데 주체는 과연 그 권력에 어떻게 저항할 수 있을까. 이 글에서는 이에 대한 가능한 답변으로 푸코의 대항인도라는 개념을 사유하는 한편, 코딩과 알고리즘, 데이터 등을 통해 작동하는 현재적 권력에 대한 대항인도의 가능성을, 현재 시행되고 있는 초중등 학교에서의 코딩 교육에서부터 탐구해 나가야 함을 제안한다. 권력의 성격과 작동 방식이 바뀌었다면, 당연하게도 저항의 전략과 실천 또한 그에 맞게 새롭게 모색되어야 하기 때문이다. This study aims to follow the aporia of power and resistance that Foucault faced, placing it in the plane of present and reading it anew. The discussion of this study is targeted at two directions, but it brings them together again. One is to follow Foucault’s discussions and examine the complex thoughts and questions about the relationship between power and resistance, and the contradictions and criticisms among them. In this article, we will briefly examine the biopower and governmentality, starting with discipline power, and critically examine the possibility of Foucault’s proposed resistance to this power(s) and the validity of such a strategy. The other is to extend this abstract and theoretical discussion into the present problematics of post-Internet power and resistance to it, so now-here and our own question. If post-Internet power is producing such a precise and sophisticated field of power through its unique techniques, mechanisms and strategies that are different from before, how can the subject resist that power? As a possible answer to this, we will consider the concept of Foucault’s ‘counter-conduct’ and look at the possibility of resistance to current power that operates through coding, algorithms, and data. And this article suggests that the possibility should be explored from coding education in the current primary and secondary schools. If the nature of power and the way it works have changed, of course, the strategy and practice of resistance should also be newly explored accordingly.
