        Comparison of Myocardial Contrast Echocardiography Versus Rest Sestamibi Myocardial Perfusion Imaging in the Early Diagnosis of Acute Coronary Syndrome

        강수진,강덕현,송재관,박성욱,박승정,송종민 한국심초음파학회 2010 Journal of Cardiovascular Imaging (J Cardiovasc Im Vol.18 No.2

        Background: It remains unclear whether myocardial contrast echocardiography (MCE) is as accurate as myocardial perfusion imaging with technetium-99m sestamibi (MPI) for the diagnosis of acute coronary syndrome (ACS). We sought to directly compare the diagnostic accuracy of MCE with resting MPI in a head-to-head fashion. Methods: We prospectively enrolled 98 consecutive patients (mean age; 59±9 years, 68 males) who presented to the emergency department with chest pain suggestive of acute myocardial ischemia. Early MCE was performed by using continuous infusion of perfluorocarbon-exposed sonicated dextrose albumin (PESDA) during intermittent power Doppler harmonic imaging. Myocardial perfusion defects observed in at least one coronary territory were considered positive. Sestamibi was injected immediately after MCE and MPI was obtained within 6 hours of tracer injection. Results: ACS was confirmed in 67 patients. There were 32 patients with acute myocardial infarction (AMI) and 35 patients with unstable angina requiring urgent revascularization. The sensitivities of MCE and MPI for the diagnosis of ACS were 72% and 61%, respectively, which were significantly higher than those of ST segment change (24%, p<0.001 vs. MCE and vs. MPI) and troponin I (27%, p<0.001 vs. MCE and vs. MPI), with similar specificities of 90% to 100%. On a receiveroperating characteristics curve demonstrating diagnostic accuracy for ACS, the area under the curve of MCE was significantly larger than that of MPI (0.86 vs. 0.77, respectively; p=0.019). Conclusion: MCE and MPI overcome the low sensitivity of routine triage tests for detecting ACS, and MCE is more accurate than MPI for the diagnosis of ACS in the emergency department. KEY WORDS:Myocardial contrast echocardiography∙Myocardial perfusion imaging∙Acute coronary syndrome.

      • 극초소형위성 STEP Cube Lab. 비행모델의 열진공시험

        강수진,정현모,이용근,강석주,서정기,오현웅 한국항공우주학회 2015 한국항공우주학회 학술발표회 논문집 Vol.2015 No.11

      • 프랜차이즈 계약방식에 따른 권리사용료의 합리적 관세평가와 국내 가맹점의 대응방안에 관한 연구

        강수진,강예진,남보라,이항 이화여자대학교 법학전문대학원 2019 Ewha Law Review Vol.9 No.-

        국내 프랜차이즈 시장은 외국 브랜드들의 주도로 성장하고 있으며, 외국에 가맹본부를 둔 프랜차이즈 브랜드들도 꾸준히 국내에서 가맹점을 늘려가고 있다. 프랜차이즈 업종의 특수성상 가맹점에 대하여 교섭력에 있어서 우위를 점하는 가맹주가 관세부담을 회피하기 위하여 가맹점에게 가격을 이전하는 등 불공정한 처우가 문제된다. 특히 가맹주가 해외로부터 상품 재료를 구입하는 경우, 그 수입상품에 대하여 실제로 지급하였거나 지급하여야 할 가격에 로열티를 가산하여 관세를 과세하여야 하는가의 문제가 관세 영역에서 중대한 문제로 대두되어왔다. 이에 WTO 가입국인 우리나라는 WTO 산하기관인 WCO의 권고의견을 반영하여 수입물품과 로열티의 관련성 및 거래조건성을 판단하고, 그에 따라 상품관련성이 인정되는 로열티에 대하여 관세를 부과하고 있다. 본 논문에서는 로열티의 지급이 프랜차이즈 계약에 따른 것인 경우 관련성과 거래조건 요건을 어떻게 적용하는지를 밝힌 WCO 권고의견 4.17을 분석하고 해외 법령 및 사례와 비교하여 불명확한 과세요건으로 인한 예측 불가능성의 문제, 관세부담의 불명확성으로 인한 조세부담의 불평등 문제, 포괄적 위임입법의 문제, 자의성의 문제, 그리고 WCO 권고의견 4.17과 국내법의 호환 문제를 지적한다. 나아가 이에 대한 해결 방안으로서 확장 해석의 금지, 본질적 부분과 비본질적 부분에 대한 차별화, ACVA의 활용을 해결방안으로 제안한다. The franchise market is growing worldwide, led by global franchise brands. In South Korea, many global franchise brands with franchise headquarters outside the country are steadily expanding its business. Along with the market expansion, franchisers' unfair treatment on franchisees became a significant issue. The unequal bargaining power between franchisers and franchisees makes it easy for franchisers to transfer prices to franchisees, which they use to avoid taxation and imposition of customs duties. This paper focuses on the question that has been a critical problem in the field of tariff: whether the duty should be levied by adding royalties to the price actually paid or payable for the imported goods when a franchisee purchased the inputs from abroad. As a member of the WTO, South Korea imposes customs in accordance with the Advisory Opinions issued by the WCO under the WTO, judging product relevance based on the relationship between imported goods and royalties and transaction conditions. In this paper, we analyze WCO Advisory Opinion 4.17, which describes how relevance and terms and conditions apply when the payment of royalties is based on a franchise agreement, and compare them with foreign laws and practices. This paper also identifies the problems regarding unfair tax burden due to ambiguity of tax requisition, the Non-blanket-delegation Doctrine, the issue of arbitrariness, and the compatibility between WCO Advisory Opinion 4.17 and domestic legislations. Lastly, we present the doctrine of strict interpretation, differentiation between essentials and non-essentials, and the implementation of ACVA as the possible solutions.

        강수진,송창현,김종규,천윤석,한창현,이영준,구세광 대한예방한의학회 2018 대한예방한의학회지 Vol.22 No.2

        Objectives : In present study, therefore, possible beneficial pharmacological activities of standard potato protein extracts (SPE) were observed on the mild diabetic obese mice. Methods : After end of 12 weeks of continuous oral administrations of three different dosages of SPE 400, 200 and 100 mg/kg, or metformin 250 mg/kg, analyzed the hepatoprotective, hypolipidemic, hypoglycemic, nephroprotective and anti-obesity effects, separately. In addition, liver antioxidant defense systems were additionally measured with lipid metabolism-related genes expressions and hepatic glucose-regulating enzyme activities for action mechanism. Results : All of diabetes and related complications including obesity were significantly inhibited by treatment of SPE 400, 200 and 100 mg/kg, dose-dependently, and they also dramatically normalized the hepatic lipid peroxidation and depletion of liver endogenous antioxidant defense system, the changes of the hepatic glucose-regulating enzyme activities, also changes of the lipid metabolism-related genes expressions including hepatic AMPKα1 and AMPKα2 mRNA expressions, dose-dependently. Especially, SPE 200 mg/kg constantly showed favorable inhibitory activities against type II diabetes and related complications as comparable to those of metformin 250 mg/kg in HFD mice, respectively. Conclusions : The present work demonstrated that SPE 400, 200 and 100 mg/kg showed favorable anti-diabetic and related complications including obesity refinement activities in HFD mice, through AMPK upregulation mediated hepatic glucose enzyme activity and lipid metabolism-related genes expression, antioxidant defense system and pancreatic lipid digestion enzyme modulatory activities.

      • 산개성단 M45(Pleiades)의 색-등급도

        강수진,오규동 全南大學校 師範大學 科學敎育硏究所 2008 科學敎育硏究誌 Vol.32 No.1

        Three color(B, V & R) CCD observation of the open cluster M45(Pleiades) were made by the Meade 102mm refractor equipped with 1K CCD camera at Chonnam National University Observatory from January 8 to March 12 2007. The CCD observation of M45 is divided into four to observe the whole area of it. The instrumental magnitude of each star is obtained to correct a magnitude difference of it between areas. The observed stars in M45 are only selected from 6 magnitude to 12 magnitude in V filter. As the result of these observation, the color-magnitude diagram of the open cluster M45 is obtained.

        영흥도 조간대 갯벌 저서미세조류의 생태적 중요성; 안정동위원소 분석 활용

        강수진,최보형,한용진,신경훈 한국하천호수학회 2016 생태와 환경 Vol.49 No.2

        In order to reconstruct a benthic foodweb structure and assess the role of benthic microalgaes as a diet source for benthos, we analyzed the carbon and nitrogen stable isotopes of diverse benthos (bivalves, crustaceans, gastropods and fishes) and potential diets (particulate organic matter, sedimentary organic matter, benthic microalgae, seagrass, and macroalgaes) in the intertidal mudflat surrounding Yeongheung Island. The δ13C values of the diets indicated wide ranges (- 26.5‰ to - 8.4‰) while benthos showed a small range of δ13C values (-12.1‰ to - 17.8‰), although they were in the same range. Except for green algaes among the macroalgaes as well as sedimentary organic matter, δ15N values of the diet candidates (5.7±1.0‰) were lighter in comparison to those of the benthos (11.8±1.9‰). Based on the δ13C and δ15N data, the benthos were classified into 3 groups, indicating a different diet and trophic position. But benthic microalgae is the most important diet source for all three benthos groups based on their stable isotope ratios, suggesting benthic microalgae should be a main diet to the intertidal ecosystem. Hence this study highlights that the biomass of benthic microalgae as biological resource should be evaluated for the management of the intertidal ecosystem of Yeongheung Island.

        ‘-겠-’의 문법화에 대한 인지의미론적 설명

        강수진 한국어의미학회 2009 한국어 의미학 Vol.29 No.-

        Kang, Soo-jin. 2009. An Cognitive semantic's explanation about grammaticization of ‘-ghet-’ in Korea. Korea Semantics, 29. This papers aims to explain developmental meaning of ‘-ghet-’ in Korea and to provide some evidence about cognitive device working at developmental meaning. One of the leading future tense in Korean language states that ‘-ghet-’ is originated from ‘-geh haeut-’(that is a causative expression). Derivation of ‘-geh haeut-’ has been a major issue since it does not only change its form, its definition has also changed from its derivation. This papers will explain what derives the change of its definition in Cognitive Semantic‘s point of view. Many previous study has been written based on ‘-ghe haeut-’ derivation (theory that says ‘-ghet-’ is originated from ‘-geh haeut-’ to ‘-heh yeut-’ to ‘-get-’), Those previous study states that the definition had changed as writter relates their axiom to meaning of a morpheme in order to explain its change. But, differenciate of this study from other studies is that this study is going to discuss that causative expression already includes future modality meaning, base on the ICM(idealized cognitive model) by G. Lakoff(1987). Also there are some example that modern language of ‘-ghet-’ includes definition of causative expression. This is one of the example when accepting request from other, have to say “al-ghet-seup-ni-da” that has future modality meaning instead of “ap-ni-da” that had present tense meaning, or “al-aht-seup-ni-da” that has past tense meaning in order to be polite. These examples support this papers' argument.

        뇌졸중 환자를 돌보는 가족간호자의 부담감에 대한 종적연구

        강수진,최스미 성인간호학회 2000 성인간호학회지 Vol.12 No.2

        This longitudinal study examines the burdens and related factors for stroke patient's primary family caregivers. Sixty-one patients treated for stroke at a general hospital in Chung-nam province and family member caregivers participated in this study from July 28. 1998 to August 1, 1999. Family caregivers' burdens were assessed by the burden scale originally developed by Zarit(1980) and Novak & Geust(1989) and modified by Oh's(1993) for use in Korea. The burden scale instrument consists of five subscales. : financial burden, social burden, physical burden, dependency burden, and emotional burden. Repeated ANOVA and Stepwise multiple regression were used in the data analyses. The results were as follows : The burden mean score was 3.23 in the hospital, 3.26 after hospital release, and 3.27 in the home environment. In the hospital, a patient's decree of cognition, and social support for family caregivers war·e significant factors affecting the sense of burden felt by family caregivers. After hospital release, the significant factors affecting the sense of burden were the degree to which stroke patients could participate in daily living activities social support for family caregivers, and changing to a second caregiver. In the home environment, the most significant factor affecting the sense of burden was social support for family caregivers.
