Background and Objectives: Little evidence is available on the optimal antithrombotic therapy following percutaneous coronary intervention (PCI) in patients with atrial fibrillation (AF). We investigated the outcomes of antithrombotic treatment strategies in AF patients who underwent PCI. Subjects and Methods: Three hundred sixty-two patients (68.0% men, mean age: 68.3±7.8 years) with AF and who had undergone PCI with stent implantation between 2005 and 2007 were enrolled. The clinical, demographic and procedural characteristics were reviewed and the stroke risk factors as well as antithrombotic regimens were analyzed. Results: The accompanying comorbidities were as follows: hypertension (59.4%), diabetes (37.3%) and congestive heart failure (16.6%). The average number of stroke risk factors was 1.6. At the time of discharge after PCI, warfarin was prescribed for 84 patients (23.2%). Cilostazol was used in addition to dual antiplatelet therapy in 35% of the patients who did not receive warfarin. The mean follow-up period was 615±385 days. The incidences of major adverse cardiac events (MACE), stroke and major bleeding were 11.3%, 3.6% and 4.1%, respectively. By Kaplan-Meier survival analysis, warfarin treatment was not associated with a lower risk of MACE (p=0.886), but it was associated with an increased risk of major bleeding (p=0.002). Conclusion: Oral anticoagulation therapy after PCI may increase hemorrhagic events in Korean AF patients.

위계 간음죄에서 위계의 대상과 인과관계

장성원 한국형사판례연구회 2021 刑事判例硏究 Vol.29 No.-

The subject judgment extends the causal relation between the object of the deceptive scheme and the deceptive scheme and adultery in the crime of adultery by the deceptive scheme. The Supreme Court widely sees the meaning of the deceptive scheme and the effect of the deceptive scheme on sexual behavior. For this purpose, the grounds of the Supreme Court are not the concept of a deceptive scheme and a connection method with adultery or a theoretical and structural approach to the causal relation itself. Rather, it is a tendency to strengthen legislatively against sex crimes under special laws, the necessity of sexual protection for juveniles, and a substantial violation of the right to self-determination. The meaning of the right to sexual self-determination, which is a common protection interest in sex crimes, is changed compared to other compulsory sex crimes when it comes to adultery under the deceptive scheme. This is based on the recognition that the right to sexual self-determination exists in a form but has been substantially violated. In this case, the question of whether the other party's right to make sexual decisions should be protected from infringement, otherwise, should be protected from criminalization. In particular, as a result of emphasizing the legal interests of sexual protection for minors, the right to sexual self-determination changes somewhat superficially. The subject judgment is to interpret the meaning of the deceptive scheme differently from the previous one by “summarizing the legislative history of adultery by the deceptive scheme, the meaning of the exercise of sexual self-determination, and the meaning of the deceptive scheme in adultery by the deceptive scheme.” The reason is that adultery under the deceptive scheme can be punished by aggravating life imprisonment. The supplementary opinion is based on the recent trend of strengthening legislation and increasing sentences to protect children and adolescents. This provides the basic logic for reinforcing and expanding punishment in interpreting the scope of deceptive schemes in adultery by deceptive schemes. The purpose of this study was to examine the interpretation of the constituent requirements and the scope of application for the types of sexual offenses that occur in cases of adultery or harassment by the method of deceptive scheme. The Supreme Court is making a judgment on the object of the deceptive scheme and the causal relation, and is showing a new position on the meaning of the deceptive scheme. In the process, the legislative approach, the approach based on the right to self-determination, and the approach in relation to the deceptive scheme and adultery are judged. While reviewing these, I tried to find out the direction of interpretation of adultery by the deceptive scheme.

심실상 빈맥의 감별진단

장성원 대한부정맥학회 2017 International Journal of Arrhythmia Vol.18 No.1

Supraventricular tachycardia (SVT) refers to a heterogeneous group of arrhythmias localized within the upper part of the heart (the His bundle or above). In general, the term SVT does not include atrial fibrillation. Common forms of SVT include atrioventricular nodal reentrant tachycardia, atrioventricular reentrant tachycardia, focal atrial tachycardia, and atrial flutter. Other, less common arrhythmias also fall under the category of SVT, including inappropriate sinus tachycardia and junctional reentrant/ectopic tachycardia. Paroxysmal supraventricular tachycardia refers to AVNRT and AVRT. SVTs can be identified and classified by clinical manifestation/physical examination, ECG, and/or electrophysiologic analysis.

The Feasibility and Efficacy of a Large-Sized Lasso Catheter Combined With 3 Dimensional Mapping System for Catheter Ablation of Atrial Fibrillation

장성원,신우승,김지훈,최민석,최윤석,오용석,이만영,노태호 대한심장학회 2011 Korean Circulation Journal Vol.41 No.8

Background and Objectives: We aimed to investigate whether a large-sized Lasso catheter could increase the success rate of immediate complete pulmonary vein (PV) antral isolation and improve the outcome of catheter ablation in atrial fibrillation (AF) patients. Subjects and Methods: This study included 107 consecutive patients (67 males, mean age: 57.8±9.7 years) who underwent PV mapping and ablation due to symptomatic drug-refractory AF. The first 43 patients underwent isolation of both ipsilateral PVs using the Carto-Merge 3 dimensional mapping system (group 1). The other 64 patients underwent isolation of both ipsilateral PVs using the same technique with a large-sized (a diameter of 30 to 35 mm) Lasso cathe-ter (group 2). When ipsilateral PVs did not show any potential after the initial circumferential ablation, we defined this as ‘immediate complete antral isolation (ICAI)’. We compared the AF recurrence rate of both groups. Results: There was no sig-nificant difference of the clinical characteristics between group 1 and group 2. All the patients were followed-up for 1 year. The ICAI rate of group 1 and group 2 was significantly different (21% vs. 78%, p<0.001), and the AF recurrence rates of group 1 and group 2 were also different (34.9% vs. 18.8%, p=0.042). Using multiple logistic regression analysis, the use of a large-sized Lasso catheter was a significant predictive factor for preventing recurrence (odds ratio: 0.489, 95% confidence interval: 0.136-0.927). Conclusion: It is likely that a large-sized Lasso catheter plays an important role in achieving ICAI and in lowering the rate of AF recurrence.

부산 스마트시티 물 데이터 협업 활용을 위한 통합플랫폼 고찰

장성원,이만희 국제차세대융합기술학회 2020 차세대융합기술학회논문지 Vol.4 No.2

최근 전 세계적으로 기후변화와 도시화로 인한 문제를 동시에 해결할 수 있는 방안으로 스마트시티에 대 한 관심이 집중되고 있으며, 정부, 도시, 기업 등 여러 이해 관계자들에 의해 스마트시티가 구축되고 있다. 기존 유비쿼터스 도시(Ubiquitous City, U-City)에서는 이수, 치수 분야별 물관리 시스템이 목적에 따라 연구되고 개별 적으로 구축이 되어왔으나 데이터 통합은 고려되지 않았다. 스마트시티에서는 물 분야 전체의 데이터 통합 및 도 시의 다른 인프라(교통, 방범, 물, 전기, 가스 등)와 도시운영 플랫폼 내에서 유기적으로 작동될 수 있도록 고려되 어야 한다. 본 연구에서는 부산 스마트시티의 도시 운영플랫폼 내에서 물 분야 플랫폼을 살펴보고, 데이터 연계를 위한 구성방안과 타 플랫폼과의 연계 방안에 대하여 고찰한다. Recently, attention has been focused on smart cities as a way to solve problems caused by climate change and urbanization all over the world. Various stockholders including governments, cities, and companies are constructing smart cities. While the Ubiquitous city (U-City) was mainly developed as a platform for individual service, water data integration was not considered. The smart city is being built as a new platform such that all the operations of traffic, security, water, electricity, and gas need to be managed cohesively after installation of the related infrastructure. In this study, we consider Busan smart city in view of water integrated platform based on water data collaboration and propose a design for water integrated platform and its collaboration with other platforms.
