[說林] 19세기 초엽 그리스의 解放과 유럽의 外交狀況
Stephanos Papadopoulos 동국사학회 1984 동국사학 Vol.18 No.-
19세기 初期에 있어서 그리스의 ?立戰爭과 그리스 ?立國家의 탄생은 발칸 역사의 劃記的인 사실일 뿐 아니라 유럽 전체에 지대한 영향을 끼쳤다. 당시 「그리스 문제」는 오리엔트 전체 문제와 직결되어 있었고 또한 나폴레옹 戰爭 후 유럽 國?社會의 外交문제와도 깊이 연결되어 있었고 따라서 神聖同盟에 심각한 타격을 주었다는데 그 역사적 意義가 있다 하겠다. 1983년 7월 28일부터 31일까지 4일간 「元明?期에 있어서 國家”支配”와 民家像의 재검토 支配 의 中國的 특질」이라는 제목의 심포지엄이 九州大學東洋史 주최로 九州大分縣九重山 筋渴은 천에서 열렸다. 마침 京部大學人交科學硏究所의 招聘敎授로 일년간 체제중이던 필자는 기회만 닿으면 해보리라던 九州地万의 여행도 겸하여 이번 학회에 참가 할 수 있게 된 것은 참으로 다행한 일이었다.

This paper investigates the relationship between corporate bond market and real economic activity. A linear model is estimated by using the Generalized Method of Moments (GMM) indicating that the yield spread of corporate bonds (AA-) relative to government bonds - a proxy of liquidity and default risk, known as external finance premium (EFP) - predicts changes in unemployment rate up to six months in the future. An impulse response analysis based on a multivariate VAR shows that a temporary increase in EFP, leads to a persistent increase in unemployment rate, notably after two to eight months. The response of unemployment rate to monetary policy shock is much lower when channel acting through the EFP is blocked off. This evidence is consistent with an operative balance sheet channel of the monetary transmission mechanism, an important result for policy makers and investors. Consequently an efficient and liquid corporate bond market, achieved through financial integration, is of essential meaning for economic growth in Korea.
The Monetary Transmission Mechanism: Evidence from Eight Economies in Transition
Stephanos Papadamou,Georgios Oikonomou 한국국제경제학회 2007 International Economic Journal Vol.21 No.4
In this paper we examine the importance of banks behavior in the transmission of the monetary policy to the real economy. Monthly data from eight economies in transition that recently became members of the European Union and the techniques of cointegration and Error Correction models are used, in order to investigate the relationship between intermediation margin spread (IMS, official lending rate minus deposit rate) and industrial production. Given the low development of corporate bond market and the dependence of non-financial agents on banking credits, we find that in many countries the IMS is an important leading indicator of industrial production. However, in countries characterized by credit access constraints (Estonia and Latvia) evidence for the traditional money channel is found. Evidence for both money and credit channels is found in Poland and Hungary. These results imply that a common monetary policy implemented by the European Central Bank may be transmitted in different ways across the new members of the enlarged European Union with different effects on real output in each country.JEL classification: E44, E52

Background and Purpose The optimal management of patients with acute basilar artery occlusion (BAO) is uncertain. We aimed to evaluate the safety and efficacy of endovascular thrombectomy (EVT) compared to medical management (MM) for acute BAO through a meta-analysis of randomized controlled trials (RCTs). Methods We performed a systematic review and meta-analysis of RCTs of patients with acute BAO. We analyzed the pooled effect of EVT compared to MM on the primary outcome (modified Rankin Scale [mRS] of 0–3 at 3 months), secondary outcome (mRS 0–2 at 3 months), symptomatic intracranial hemorrhage (sICH), and 3-month mortality rates. For each study, effect sizes were computed as odds ratios (ORs) with random effects and Mantel-Haenszel weighting. Results Four RCTs met inclusion criteria including 988 patients. There were higher odds of mRS of 0-3 at 90 days in the EVT versus MM group (45.1% vs. 29.1%, OR 1.99, 95% confidence interval [CI] 1.04–3.80; P=0.04). Patients receiving EVT had a higher sICH compared to MM (5.4% vs. 0.8%, OR 7.89, 95% CI 4.10–15.19; P<0.01). Mortality was lower in the EVT group (35.5% vs. 45.1%, OR 0.64, 95% CI 0.42–0.99; P=0.05). In an analysis of two trials with BAO patients and National Institutes of Health Stroke Scale (NIHSS) <10, there was no difference in 90-day outcomes between EVT versus MM. Conclusion In this systematic review and meta-analysis, EVT was associated with favorable outcome and decreased mortality in patients with BAO up to 24 hours from stroke symptoms compared to MM. The treatment effect in BAO patients with NIHSS <10 was less certain. Further studies are of interest to evaluate the efficacy of EVT in basilar occlusion patients with milder symptoms.

An investigation of the effectiveness of the interface treatment when column concrete jacketing is performed is presented. Alternative methods of interface connection were used in order to investigate the performance of strengthened concrete columns. These connecting techniques involved roughening the surface of the original column, embedding steel dowels into the original column and a combination of these two techniques. The experimental program included three strengthened specimens, one original specimen (unstrengthened) and one as-built specimen (monolithic). The specimens represented half height full-scale old Greek Code (1950's) designed ground floor columns of a typical concrete frame building. The jackets of the strengthened specimens were constructed with shotcrete. All specimens were subjected to displacement controlled earthquake simulation loading. The seismic performance of the strengthened specimens is compared to both the original and the monolithic specimens. The comparison was performed in terms of strength, stiffness and hysteretic response. The results demonstrate the effectiveness of the strengthening methods and indicate that the proper construction of a jacket can improve the behaviour of the specimens up to a level comparable to monolithic behaviour. It was found that different methods of interface treatment could influence the failure mechanism and the crack patterns of the specimens. It was also found that the specimen that combined roughening with dowel placement performed the best and all strengthened columns were better at dissipating energy than the monolithic specimen.
