본 논문은 유럽의 재정위기와 이에 대한 유럽 차원의 대응을 검토하고 평가하는 것을 목적으로 한다. 유럽은 지난 2007-2011년 글로벌 금융위기의 여파로 그리스의 부채위기로 시작된 경제위기가 전유럽으로 확산되어 현재 총체적 위기를 맞고 있다. 특히 국가 부채 위기(sovereign debt crisis)가 심화되어 유럽 연합과 유로존 미래까지 불투명한 상태이다. 이에 대한 유럽 연합과 ECB의 대응은 근본적인 해법보다는 위기의 여파를 잠재우는 단기적인 해법에 의존하고 있다. 이는 지난 금융위기 대응에서 미연준이 전개하였던 비관행적 통화신용정책(unconventional momentary policy)과 유사하다. ECB의 비표준 통화신용정책 조치(non-standard measures)가 그것이다. ECB는 미국의 비관행적 통화신용정책과 나름 차별점을 부각하고 있으나, ECB의 SMP, OMT와 EFSF, ESFM 그리고 향후 유럽 위기 상설 대응 기구로 작동하게 될 ESM의 정책들은 미국의 사례에서 보다 훨씬 더 강력한 비관적 통화신용정책이 될 것이다. 이러한 정책 수단의 수행 결과 유럽은 미국보다 훨씬 더 고위험의 통화체계와 통화체계에 의해 지탱되는 미래 잠재적 재정위기의 심화로 이어질 것이다.

Purpose : the purpose of the present study was to compare the shear strength of the three techniques for the fixation of simulated sagittal split ramus osteotomies in terms of their ability resist vertical loads. Materials and Methods : Fifteen bovine ribs of similar size and shape were subjected to uniform osteotomies resembling a sagittal split ramus osteotomy. They were divided into three groups as wire, screw and plate group. The osteotomitized fragments were fixed with 18 gauge stainless steel wire, three bicortical screws, and with a 4-hole miniplate and monocortical screws in the wire, secrw and plate group respectively. The fixed bovine rib specimens were secured in a jig, subjected to vertical loads, and evaluated for mean shear strength at failure and for mean weight resisted by the wire, screw, and miniplate. Results : The mean weight resisted by the wire, screw and miniplate was (1.01±0.40g/㎣), (8.87±3.95g/㎣) and (6.93±2.82g/㎣) respectively. The mean weight resistances in the screw and miniplate group were significantly higher than those of the wire group (p<0.05). But no significant differences existed between the screw and plate group (p>0.05). Conclusion : These results suggest that the both screw and miniplate fixation have higher mean weight resistances than wire fixation and both methods would be much better for rigid internal fixation than wire fixation after sagittal split ramus osteotomy.

This paper analyzes the effects of the American Federal Reserve System’s influence on the federal funds market and several types of benchmark rates, such as the: IOER, ON RRP andEffective Federal Fund Market Rate, through an analysis of the assets and liabilities of the Fed balance sheet. In this way, the current Fed multi-benchmark rate system has proved to be unstable as long as the Fed's normalization is not achieved. 이 논문은 연준 대차대조표의 자산과 부채 항목의 분석을 통해, 연준의 연방기금시장에서의 영향력(금융시장의 통제력)과 최근 5년간의 다중 기준금리체계실험을한데 엮어 분석하였다. 이를 통해 현재의 연준 다중 기준금리체계는 연준의 유동성회수가 이뤄지지 않는 한 계속해서 불안정한 상태를 이어갈 수밖에 없다는 것을규명하였다.

Maxillary sinus has an anatomic limitation to bone support available for dental implant. When there is less than 10㎜ of bone remaining between the upper alveolar ridge crest and the maxillary sinus floor, bone augmentation should be considered. In 1994, Summers reported two sinus floor elevation techniques of limmediate implant insertion, using osteotomes, for patients who have at least 5㎜ of bone remaining between the alveolar ridge crest and the maxillary sinus floor. One technique is osteotome sinus floor elevation (OSFE) procedure in which uses osteotomes to elevate the sinus floor. The other is bone-added OSFE (BAOSFE) procedure in which bone graft is added into osteotomy site. Both procedures conserve all of the remaining bone and selectively displace it upward, thereby raising sinus floor. This study was aimed to evaluate the long-term success rate of implants which had been placed by osteotome sinus floor elevation procedure. Between February 1996 and June 1998, 10 implants were placed using OSFE or BAOSFE procedures in 6 patients who had at least 6㎜ of bone remaining between the alveolar ridge crest and the sinus floor. OSFE procedures were performed in patiens, 2∼4㎜ sinus floor elevation was needed, whereas BAOSFE procedures were done in patines, more than 4㎜ sinus floor elevation was needed. During the mean follow-up period of 4 years 4 months (3 years 6 months ∼ 5 years 9 months), no implant was failed and all patients showed good functional results. OSFE and BAOSFE procedures seemed technically easier and less invasive compared to conventional sinus lift procedure. And both procedure have good success rate.
