      • 유전자 알고리즘과 신경 회로망의 결합에 관한 연구 조사

        송윤선,김명원,김종문,Song, Y.-S.,Kim, M.W.,Kim, J.M. 한국전자통신연구원 1994 전자통신동향분석 Vol.9 No.4

        최근 생물학에 기반을 두고 최적화 문제와 학습 문제에 많이 사용되고 있는 유전자 알고리즘과 신경 회로망 기술을 결합하는 연구가 활발해 지고 있다. 신경 회로망 연구에 비해 조금 늦게 시작된 유전자 알고리즘에 대한 연구는 유전자 복제, 교차, 돌연 변이 등의 현상을 걸쳐서 새로운 개체를 발생시켜 나가는 진화의 과정에서 착안하여 해결하고자 하는 문제의 해답을 유전자 탐색의 과정을 통하여 찾아내는 것이다. 이 글에서는 유전자 알고리즘과 신경 회로망을 혹은 서로 보조적인 입장에서 혹은 동등한 입장에서 결합하는 연구에 대한 조사를 소개함으로써 보다 복잡한 최적화 문제나 자동 프로그래밍, 기계 학습, 복잡한 자료 분석, 시계열 예측 등의 분야에 응용하는데 도움을 주고자 한다.

        오염 지중환경 특성화와 자연저감평가를 위한 말단전자수용과정(TEAPs) 분석 및 평가기술 소개

        송윤선,김한석,권만재 한국지하수토양환경학회 2020 지하수토양환경 Vol.25 No.특별호

        Monitoring and assessing terminal electron accepting processes (TEAPs) are one of the most important steps to remediatecontaminated sites via various in-situ techniques. TEAPs are a part of the microbial respiration reactions. Microorganismsgain energy from these reactions and reduces pollutants. Monitoring TEAPs enables us to predict degradability ofcontaminants and degradation rates. In many countries, TEAPs have been used for characterization of field sites andmanagement of groundwater wells. For instance, US Environmental Protection Agency (EPA) provided strategies forgroundwater quality and well management by applying TEAPs monitoring. Denmark has also constructed TEAPs map oflocal unit area to develop effective groundwater managing system, particularly to predict and assess nitrogencontamination. In case of Korea, although detailed soil survey and groundwater contamination assessment have beenemployed, site investigation guidelines using TEAPs have not been established yet. To better define TEAPs in subsurfaceenvironments, multiple indicators including ion concentrations, isotope compositions and contaminant degradationbyproducts must be assessed. Furthermore, dissolved hydrogen concentrations are regarded as significant evidence ofTEAPs occurring in subsurface environment. This review study introduces optimal sampling techniques of groundwaterand dissolved hydrogen, and further discuss how to assess TEAPs in contaminated subsurface environments according toseveral contamination scenarios.

        한반도 군정 사례의 미래 안정화작전 시사점 분석

        송윤선 육군사관학교 화랑대연구소 2020 한국군사학논집 Vol.76 No.1

        The purpose of this study is to get the implication of the cases of Military Government in Korean Peninsular for Stability Operations that may be in Korean Peninsula in the future. This study reviews 3 historical cases since 1945, focusing on how the Military Governments had been proceeded in Korean Peninsular. The cases are the Military Government in South Korea from 1945 to 1948, the Military Government in North Korea in 1950, and the Military Government in the restored area north of 38 line of South Korea from 1951 to 1954. The study indicates that a constant pattern in its process and the conflicts between Korean Authority and the US Forces Command in the past Military Governments may take place again in Stability Operations in the future in Korean Peninsular. 본 연구는 과거 한반도에서의 군사적 점령지역에 대한 군정(안정화작전)이 어떻게 전개되었는지 역사적 사례를 고찰하여 국가적, 전략적 차원에서의 작전 수행 절차와 이를 위한 대비 방향에 대한 시사점을 얻는데 연구 목적을 두고 있다. 이를 위해 우리나라에서 있었던 해방 직후 한반도에 진주한 미군에 의한 안정화작전과 6·25 전쟁시 유엔군 점령 지역에서의 안정화작전 사례를 분석하고자 한다. 과거 미군에 의한 한반도에서의 안정화작전 사례 연구는 오늘날 급변사태나 전면전시 북한지역에 대한 안정화작전 수행간 한국적 특수성으로 인해 발생할 수 있는 다양한 현상들을 추론하고 이에 대한 대비 방향 등을 모색하는데 도움을 줄 것이다.

        Inhibition of Angiogenesis by Propolis

        송윤선,박은희,KyungJaJung,진창배 대한약학회 2002 Archives of Pharmacal Research Vol.25 No.4

        (Received May 9, 2002) Propolis, obtained from honeybee hives, has been used in Oriental folk medicine as an antiinflammatory, anti-carcinogenic, and immunomodulatory agent. There is considerable evidence suggesting that angiogenesis and chronic inflammation are codependent. Blockage of angiogenesis results in an anti-inflammatory effect. Ethanol (EEP) and ether extracts of propolis (REP), and caffeic acid phenethyl ester (CAPE), an active component of propolis, were examined for their anti-angiogenic activities using the chick embryo chorioallantoic membrane (CAM), and the calf pulmonary arterial endothelial (CPAE) cell proliferation, assays. The presence of EEP, REP and CAPE inhibited angiogenesis in the CAM assay and the proliferation of CPAE cells. The results suggest that anti-angiogenic activities of EEP, REP and CAPE are also responsible for their anti-inflammatory effect.

        시대 변화에 따른 전시계엄 제도 개선 방안

        송윤선 한국국방연구원 2016 국방정책연구 Vol.32 No.1

        Martial law is a national emergency power system to cope with national crises. The study recommends the way to develop Korea`s martial law system according to periodic changes. First, Emergency Martial Law and Precautionary Martial Law should be clarified on their concepts and the limitation of authority given to the military. Second, martial law should be declared only for ``armed`` cases. Third, the military authority should intervene civil administration ``individually`` only ``in case of a must``. Fourth, wartime martial law should be focused on helping the Government implement ``Chung-mu Plan``. Fifth, Military Courts may delegate their jurisdiction on less important criminals to civilian courts. Sixth, the martial forces need to be committed mainly for military purposes. Last, the Martial Law Command needs to recruit specialists for controlling cyberspace and establish the structure for collaboration with related agencies across the military.

        Clinical Manifestation and Radiologic Patterns of Spontaneous Cervicocephalic Dissection According to the Anatomic Location: A Single-Center Analysis in Korean Patients

        송윤선,Park Sang Ik,Budianto Pepi,Kwon Boseong,Suh Dae Chul 대한신경중재치료의학회 2022 Neurointervention Vol.17 No.2

        Purpose Spontaneous cervicocephalic dissection (SCAD) is an important cause of stroke and shows various lesion locations and clinical features. The purpose of this study was to analyze the location of SCAD and its clinical and radiologic patterns in Korean patients. Materials and Methods Patients with SCAD who were evaluated between 2013 and 2018 at a tertiary center in Korea were reviewed. We classified and compared the morphological (aneurysm or steno-occlusion) and presenting (hemorrhage or infarction) patterns according to the lesion locations (anterior circulation [AC] vs. posterior circulation [PC]; intradural [ID] vs. extradural [ED]). Results A total of 166 patients were included in this study. The SCAD most commonly occurred in the PC-ID location (65.1%), followed by AC-ID (13.3%), AC-ED (13.3%), and PC-ED (8.4%). Aneurysm and steno-occlusion patterns were observed in 66.9% and 57.8% of the cases, respectively. The aneurysm pattern was significantly more common in the PC-ID location (78.7%) than in other locations. As for the presenting pattern, cerebral infarction was the most common pattern (39.8%), and intracranial hemorrhage was observed only in the ID location (7.2%). Conclusion In Korean patients, PC-ID, especially ID vertebral artery, was the most common location of SCAD, and most cases were accompanied by an aneurysm. It also suggested that these location trends differ by population or ethnicity.

        Alpha Stent for Coiling of Unruptured, Wide-Necked, Distal Internal Carotid Artery Aneurysms: Safety and Effectiveness at 6 Months

        송윤선,신재준,김중구,이상훈,조수희,박중철,최충곤,이덕희 대한영상의학회 2020 Korean Journal of Radiology Vol.21 No.2

        Objective: The Alpha stent (CGBio), a new intracranial stent featuring a re-sheathable mesh design with improved wall apposition at the curved segment, was clinically evaluated. We report the 6-month follow-up results from a prospective, singlecenter study in which the stent was used for coiling of wide-necked distal internal carotid artery (ICA) aneurysms. Materials and Methods: Between April 2016 and 2018, 50 patients (mean age, 56.5 years, 45 females [90%]) with 54 unruptured distal ICA aneurysms (average diameter: 5.6 ± 1.7 mm) were enrolled. The primary endpoint for effectiveness was successful coil embolization with the Alpha stent, and subsequent complete or near-complete occlusion at the 6-month magnetic resonance angiography assessment. The primary safety endpoint was the absence of serious adverse events (SAEs) up to 6 months from the procedure. Results: The primary effectiveness endpoint was observed in 94.4% (51/54) aneurysms. In one patient with technical failure, the stent could not be deployed because of parent artery tortuosity; therefore, a different type of stent was used. Of the 53 aneurysms treated with the Alpha stent, complete occlusion was achieved in 64.1% (34/53) cases, and near-complete occlusion was achieved in 32.0% (17/53) cases by the 6-month follow-up. Two cases (3.7%) required retreatment because of major recurrence. In 4% (2/50) patients, SAEs, i.e., retinal artery thromboembolism and corona radiata lacunar infarction, were reported after the procedure. Conclusion: For endovascular treatment of unruptured, wide-necked, distal ICA aneurysms, coil embolization using the newly developed Alpha stent showed excellent procedural and mid-term clinical follow-up results in terms of effectiveness and safety.
