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.

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.

심장수술후 심근의 부종, 심근이완, 심한 술후 출혈 등이 동반된 환자에서는 흉골봉합에 의해 심한 혈역학적 장애가 발생된다. 심한 심부종으로 흉골 봉합시 흉골 일부분에 의한 심압박에도 혈혁학적 장애를 일으키는 경우도 있다. 본 교실에서는 54세의 비만 여성에서 관상동맥 우회술후 Synthes DCP wide plate를 이용한지 연성 흉골 봉합을 경험하였으며, 이러한 지연성 흉골봉합이 심부종이 심한 환자에서는 상당히 효과적이고 간단한 방법임을 확인하였다. 관상동맥 우회술후 16시간만에 성공적으로 지연성 흉골봉합을 경칩하여 좋은 성적을 얻었기에 보고 하고자 한다. 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.

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.

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.

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.

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

흰민들레 추출물에서 분리한 taraxinic acid, dihydrotaraxinic acid 및 luteolin를 대상으로 화장품의 미백 소재로서의 이용 가능성을 조사하였다. In vitro tyrosinase 저해 활성은 100 ㎍/mL에서 대조군인 ascorbic acid는 42% 저해 활성을 보였으며, luteolin은 48%, taraxinic acid는 29%, 그리고 dihydrotaraxinic acid는 18%를 보여 luteolin이 가장 높게 나타냈다. Taraxinic acid와 dihydrotaraxinic acid는 100 ㎍/mL 이하의조건에서 B16BL6 멜라닌 형성 세포의 생존율에 영향을 미치지않았으나, luteolin은 강한 세포 독성을 나타냈다. Taraxinic acid와 dihydrotaraxinic acid가 세포 생존율에 영향을 미치지않는 농도 범위(10, 50, 100 ㎍/mL)에서 B16BL6 세포 내 멜라닌생합성 및 tyrosinase 활성을 확인한 결과 농도 의존적으로 억제하는 것으로 확인되었다. 특히 taraxinic acid는 tyrosinase inhibitor로 알려진 arbutin보다 뛰어난 저해 활성을 나타내어, 천연 기능성 미백 화장품 원료로 사용 가능성이 기대된다. 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

통일 후 북한토지제도 재편과 사유화 방안 연구

박승일 ( Park Seung Il ) 북한연구학회 2018 北韓硏究學會報 Vol.22 No.1

통일 후 북한의 토지소유제도 재편은 사회주의 체제를 시장경제체제로 전환하는데 있어 가장 핵심적인 요소이다. 토지에 대한 사유화 문제는 개인의 재산권과 밀접하게 연관되어 있을 뿐만 아니라, 그 절차나 방법 여하에 따라 사회경제적 파급효과가 크다. 북한과 같은 사회주의 중앙집권 계획경제체지가 시장경제체제로 체제를 전환하는데 있어서 특징적 요소는 자유화(Liberalization), 안정화(Stabilization), 사유화(Privatization)이다. 과거 구 사회주의국가들의 체제전환 경험을 비추어보면 사유화가 가장 어려운 과제임을 알 수 있다. 통일한국의 경우 이념, 문화, 경제 등에서 많은 난관이 예상되지만 남북 통일과정에서 북한지역의 토지 등 부동산에 대한 재산권 문제의 처리는 중대한 특히 재산권 문제가 큰 사회적문제가 될 것이다. 통일 후 북한토지제도의 재편에 관련한 연구는 분단 이후부터 최근까지 꾸준하게 연구가 진행되고 있는 분야이다. 최근 연구동향을 살펴보면, 원상회복형(원칙적 반환, 예외적 보상), 원소유자 보상형(금전적 보상), 전면적 국유화형(토지공공임대제도), 무상분배형의 4가지 유형으로 구분할 수 있다. 이러한 시점에서 본 연구는 통일에 대비한 북한토지제도의 법적과제를 검토하므로 통일 후 발생할 수 있는 법적 제 문제를 사전에 방지 또는 최소화함을 목표로 한다. 본 연구의 목적은 남·북한통일후 북한토지제도 재편을 위한 법적과제가 무엇인지 살펴보는 것이다. 먼저 북한 토지제도의 현황과 법령체계에 대하여 살펴보고, 통일독일의 토지제도 재편 경험과 북한토지제도의 변화 전망에 대하여 살펴볼 것이다. 북한지역 몰수토지제도에 대한 통일한국의 보상기준을 살펴본 후 북한토지제도 재편을 위한 법적과제를 제시하고자 한다. While privatization of land is closely related to personal rights to properties, it may have a substantial socio-economic impact depending on procedures and how we make it happen. Therefore, reorganization the land management system (LMS) in North Korea is certainly one of the most critical factors in the state’s transition from socialism to a market economy following the reunification of the Korean Peninsula. In the centralized socialist planned economy, such as North Korea cheji to switch the system to amarket economyit is characterized by elements liberalization(Liberalization), stabilization( Stabilization), privatization(Privatization). In light of the transition experiences of the past nine socialist countries it shows tha tprivatization is the most difficult task. While we expect to see numerous obstacles in many fronts―including ideology, culture, and economy―in the way forward for the unified Korea, issues concerning property rights will account for some of the greatest parts of social problems. In this context, our research focus should be on resolving legal challenges in reorganization the LMS in North Korea. There has been a continued research effort on this issue so far. Current research trends suggest four types of possible solutions: recovery of ownership (priority on returning land to original owners, or making reparations if not possible); reparation to original owner (financial compensation); full-fledged nationalization (public lease system); and free distribution of land to citizens. Against this backdrop, I intend to focus on reviewing predictable legal challenges in North Korean LMS in the unified Korea in this research, thereby preventing or minimizing potential legal problems in the system following the reunification. The purpose of this paper is to take a closer look into legal challenges in reorganization the LMS in North Korea after the reunification. To this end, it will start from the status quo of the existing LMS and legislations in North Korea. Then it will shed some light on how the Unified Germany revised its LMS, and move on to the outlook for the possible changes in the North Korean system. Following up with prospects of compensation standards for the confiscated lands in the unified Korea, the paper will then present the legal challenges in reorganization the North Korean LMS.

A main composition of the lightweight aggregate is a polycrystal qualitative plastic because of the fact, the characteristic of the aggregate is that the vast quantity of air gap is formed inside the aggregate. t As a matter of the characteristic, the moisture in the aggregates tends to move irregularly according to the change in the outer condition. Consequently a measure to solve the problem is needed. In this research as a part of the study on the performance improvement of light weight aggregates by coating, the absorptance variation and the change on time of the coated light weight aggregates were compared and analyzed for ensuring the workability of lightweight aggregates concrete by preventing from absorption to inner aggregates by impregnation of water repellent and oil repellent.
