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.

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.

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

박승일,김용진,Park, Seung-Il,Kim, Yong-Jin 대한흉부심장혈관외과학회 1989 Journal of Chest Surgery (J Chest Surg) Vol.22 No.2

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.

흰민들레(Taraxacum coreanum)에서 분리한 taraxinic acid의 tyrosinase 활성저해 및 melanin 생성저해 효과

박승일(Seung Il Park), 윤혜련(Hye Ryeon Yoon), 신준호(Jun-Ho Shin), 이성주(Sung Joo Lee), 김도윤(Do Yoon Kim), 이환명(Hwan Myung Lee) 한국자원식물학회 2021 한국자원식물학회지 Vol.34 No.4

This study was to investigate the Taraxinic acid from Taraxacum coreanum on tyrosinase activity and melanogenesis. In B16BL6 cell, Taraxinic acid did not show cytotoxicity even at concentrations of up to 100 ㎍/mL. In addition, tyrosinase inhibitory activity and melanogenesis inhibitory activity were confirmed by stimulation with α -melanocyte stimulating hormone (α-MSH) in the presence of taraxinic acid. Taraxinic acid was added to cells at concentrations of 10, 50 and 100 ㎍/mL and treated for 48 hours to confirm tyrosinase inhibitory activity and melanin production. The tyrosinase inhibitory activity increased in proportion to the amount of the sample, and showed an inhibitory activity of about 54.5% at a concentration of 50 ㎍/mL. Melanin production decreased in proportion to the sample amount, and it was about 62.2% at the concentration of 10 ㎍/mL. From the above results, it was found that Taraxinic acid had higher tyrosinase activity and melanin synthesis inhibitory activity in melanocyte than arbutin. The results suggest that Taraxinic acid can be utilized in natural whitening cosmetics

인터넷과 관리권력 그리고 관리사회

박승일(Seung Il Park) 사단법인 언론과 사회 2018 언론과 사회 Vol.26 No.2

이 글은 관리권력이라는 개념을 제안하고 그 필요성과 유효성을 점검해 보는 데 일차적인 목적이 있다. 포드주의에서 포스트 포드주의 혹은 신자유주의로의 이행은 지배적인 규제양식의 변화를 동시에 수반하는 만큼, 이와 맞물려 있는 권력관계의 변화 또한 보다 정확한 개념으로 포착해낼 필요가 있다. 관리권력이라는 개념이 바로 그것인데, 이는 푸코의 통치성 개념을 이어받으면서도 그 문제의식을 인터넷 이후의 시대인 현재적 관점에서 새롭게 읽어내기 위한 것이라 할 수 있다. 통치성의 문제설정이 신자유주의와 긴밀하게 연결되어 있다고 한다면, 그것은 또한 신자유주의적 재구조화와 상호 조건적 관계를 이루는 정보화 사회로의 전환과도 그만큼 분리 불가능하게 얽혀 있을 수밖에 없다. 그렇다면 이제 관건은 인터넷이라는 장치의 고유한 특징과 그 지배적인 상황에 맞게 통치성의 문제설정을 새로이 도출해 내는 것이며, 더 나아가 이러한 개념적 전유를 통해 인터넷이 권력 그 자체로 작동해 가는 구체적이고 현재적인 방식과 기법, 전술 등을 포착해 내는 것이다. 이를 위해 이 글은 정보통신기술의 고유한 작동 방식이 신자유주의의 가치화 메커니즘 및 포섭의 전략과 상호 조응하면서 구체화되는 양상을 ‘노동의 사회화’와 ‘정신의 기계화’ 과정으로 구분하고, 이를 다시 ‘환경의 관리’와 ‘정신의 관리’라는 자체의 원리를 따라 각각 ‘환경관리권력’과 ‘정신관리 권력’으로 개념화하고자 했다. 이 이중의 관리권력은 그 원리와 메커니즘 면에서는 서로 구분되지만 전체적으로는 상보적인 관계로 결합되며, 그리하여 관리사회라는 독특한 사회적 짜임을 이루게 된다. 인터넷과 관리권력, 그리고 관리사회라는 이 글의 문제설정이 이렇게 도출된다. This study has a primary purpose in suggesting the concept, the control power as well as reviewing its necessity and effectiveness. As the transition from Fordism to post-Fordism, or to neoliberalism entails a change in the dominant mode of regulation, it is also necessary to capture the changes in power relations that are associated with the mode of regulation more accurately concept. The control power, which is derived from the concept of governmentality Foucault advanced, provides better explanation on the new mode of regulation in the post-Internet period. If the problematics of the govenrmentality is closely linked to neoliberalism, then it is also inseparably intertwined with the transition to an information society that with interconditional relations to neoliberal restructuring. Accordingly, the key is to derive a new set of problematics of governmentality that fit the unique characteristics of the Internet device and its dominant context, and furthermore, this conceptual appropriation captures the concrete and current ways, techniques, and tactics that the Internet operates as power itself. In order to suggest a new concept, this study conceptualizes the way in which the unique way of operation of information and communication technologies interacts with the valuation mechanism and subsumption strategies of neoliberalism as the socialization of labor and the mechanization of mind. The socialization of labor and the mechanization of mind are further conceptualized respectively as the environmental power and the psycho power, with the consideration of their principles, control of environment and control of psycho. These double control powers are distinguishable in terms of principle and mechanism, but each is combined into a complementary relationship as a whole. So that they have a unique configuration of the society of control. This leads to the main problematics of this study as the Internet, the control power, and the society of control.

신자유주의 통치성과 ‘환경설계를 통한 범죄 예방(CPTED)’

박승일(Park, Seung-IL) 비판사회학회 2015 경제와 사회 Vol.- No.107

이 글은 CPTED를 신자유주의와 ‘함께’ 읽어내려는 시도이다. 무엇보다 이 글은 CPTED의 메커니즘을 파악하고 이를 바탕으로 CPTED와 신자유주의 통치성 사이의 친화성을 규명하는 데 초점을 맞추고 있다. 결론적으로 말하면, 신자유주의 통치성과 CPTED는 적어도 세 지점에서 교차 및 조응하면서 일정한 선택적 친화성을 형성한다. 환경 개입과 보험회계주의 그리고 주체의 자기 통치, 이 세 요소는 신자유주의 통치성의 작동 원리이자 또한 동시에 CPTED를 움직이는 핵심 동력이기도 하다. 즉 신자유주의 통치 전략은 환경에 개입해서 범죄의 기회를 차단하는 형태로 그리고 보험회계적인 리스크 관리와 주체들의 자발적인 참여를 이끌어내는 형태로 시큐리티 확립의 실천들을 일상 속에 착근시켜 왔으며, 특히 이 가운데 CPTED와 같은 안전장치들을 적극 활용해왔다. 이와 나란하게, CPTED 또한 여기에 조응하면서 일상 환경의 설계와 범죄에 대한 사전적 예방관리 그리고 (규율이 아닌) 조절 메커니즘 등을 기본 골격으로 삼아 신자유주의 통치 원리를 물질적·제도적·기술적인 차원에서 현실화·구체화해왔다. 여기에는 인과관계는 아니지만, 그러나 분명한 친화성이 존재한다. 요컨대 신자유주의 통치성의 확립과 이로 인해 열려진 시큐리티 합리성의 문제설정 위에서야 CPTED라는 장치가 지금과 같은 형태로 자리를 잡을 수 있었으며 또 이만큼의 성공과 확산을 이룰 수 있었다. 뒤집어 말한다면, CPTED는 자체의 원리와 메커니즘을 신자유주의의 통치 전략과 공명시키는 한에서만, 혹은 그 구조적 격자 속으로 편입되는 한에서만 포스트 케인스주의적 치안 활동의 한 줄기를 형성할 수 있었다. 신자유주의와 CPTED를 함께 읽는다는 것은, 그러므로 신자유주의 통치성의 문제계 안에서 CPTED를 이해하고 정확히 이와 함께 CPTED로부터 신자유주의 통치 전략을 연역해내는 동시적 사유에 다름 아니다. This paper aims at understanding ‘Crime Prevention through Environmental Design(CPTED)’ in a consideration of neoliberalism. More specifically, it deals with the mechanism for CPTED, which further investigates the affinity between CPTED and neoliberal governmentality. Neoliberal governmentality has similar characteristics with CPTED and forms elective affinity in terms of three aspects: ‘environmental intervention’, ‘actuarialism’, and ‘governing the self.’ These factors are operating principles of neoliberal governmentality and also the driving force of CPTED. In other words, strategies for neoliberal governmentality are to prevent crime opportunity by engaging in environments and to manage actuarial risks and encourage active participation of the subject. These strategies have embedded the practices to establish security in our everyday lives and utilized dispositif of security such as CPTED. Similarly, by using everyday environment design, crime prevention, management, and regulation mechanism as basic framework, CPTED has realized and specified neoliberal governmentality in material, institutional, and technical aspects. In doing so, the affinity between neoliberal governmentality and CPTED -even though it is not causal relationship- plays an important role. Based on these establishment of neoliberal governmentality and security rationality, CPTED as dispositif has achieved the current success and spread. In the other way around, CPTED can be considered as post-Keynesian policing by sharing operating principles and mechanism with neoliberal governmentality strategies or being included into neoliberal structural framework. Therefore, to understand the relationship between neoliberalism and CPTED, CPTED should be taken into account in a close relationship with problematique of neoliberal governmentality; and at the same time strategies for neoliberal governmentality should be deduced from CPTED.

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.
