로스쿨 법안 통과 후 국내의 많은 대학들이 사활을 걸고 로스쿨 유치를 위해 사력을 다하고 있다. 이에 로스쿨 유치를 희망하는 대학들 간의 공통된 의견과 함께 대비되는 의견은 무엇인지, 인적·물적 인프라 구축정도 및 교육과정과 교육방법, 대학별 특성화전략 등에 대해 알아봄으로써 우리 대학들이 로스쿨을 어떻게 준비해왔고, 추진해왔는지 살펴보고자 한다.

The purpose of this study was to evaluate bending performance of concrete filled soldier pile for temporary retaining wall. Structural performance tests were conducted on total number of four specimens. Each specimen had a unique characteristics with combination of the following variables, existence of reinforcing bar and locations of reinforcing steel plates. The results of this study were as follows; concrete filled steel tubes with being reinforced bar and flange rather than non-bar showed better performance. Higher yield, tensile strength and sufficient plastic strain were archived and maximum moment observed in experiments exceeded theoretical maximum moment in both allowable stress design and limit state design at all specimens.

In a P2P environment, effective selection of peers where download file piece can improve download speed. In this paper, we design and implement a bittorrent system that can improve file download speed considering the performance criterion and mechanism such as maximum upload speed and round trip time between peers that can affect performance improvement. We define larger maximum upload speed and smaller the round trip time as healthier the peers. We coded that the healthy peer is selected first when download file. We verified that this mechanism can contribute to download speed improvement through performance evaluation in various network environments. Improved torrent considering suggestion of this thesis is about 10% better than original in internet environment. However, in intranet environment, there is almost no improvement.

The purpose of this study is to consider structural issues and analyze construction sequences when constructing hanging floors supported by Mega truss. Since suspended structures were supported by the Mega truss, vertical load on suspended structures was needed to transfer from low to high. Deflection management of structures was the primary point under construction. The results of this study were as follows; The steel structures, which has relatively lighter self-weight, were constructed upwards after the base floor steel truss erection. Concrete Placing, which has relatively heavier self-weight, were performed in two phases to minimize structure’s deflection. Slab was placed downwards from the top floor to lower floor whereas column was places upwards. Deflection measurements were carried out at every construction sequences.

The aim of this study was to investigate the epidemiological characteristics and changing patterns of gallstone disease over the last 20 years. Methods: Four thousands and twenty gallstone patients who had received surgery at Seoul National University Hospital (1981~2000) were analyzed according to time of treatment; period I: 1981~1985 (831 cases), period II: 1986~1990 (888 cases), period III: 1991~1995 (1,040 cases) and period IV: 1996~2000 (1,261 cases). Data from 13 institutes in Korea reporting 13,101 gallstone cases were also reviewed with literature to elucidate the nation-wide trends. Results: The number of gallstone cases has gradually increased. A female-predominance was not observed (F/M=1.17-1.37). The CBD stone patients were older than the GB and the IHD stone patients. Over the study period, the relative portion of the GB stone group increased. The portion of CBD stone group decreased, while that of the IHD stone group was unchanged. The rural pattern of gallstone disease (low GB stone, high CBD and IHD stone) has become similar to the urban pattern. Such patterns are well agreed with the other literature reported in Korea. Conclusions: The pattern of gallstone disease in Korea has become similar to that in Western countries except a high prevalence of hepatolithiasis. (Korean J Gastroenterol 2003;42:415-422)

목적 : 심혈관 자기공명영상의 발달은 생존심근의 진단에 많은 도움을 준다고 보고되고 있다. 저자들은 이러한 사실을 직접 규명하고자 본 연구를 시해하였다. 방법 : 급성 심근경색증으로 혈관 재개통술을 시행받은 19명의 환자에서 심혈관 자기공명영상을 얻었다. 자기공명영상은 좌심실을 32분절로 나누어 각각의 심근벽 운동과 후기조영 증강 정도를 결정하였으며 6개월 뒤 추적 관상동맥 조영술과 자기공명영상을 다시 얻어 비교 분석하였다. 결과 : 총 628개의 분절 중 177개의 분절에서 심근벽 운동의 이상을 보였으며 이 분절을 대상으로 분석을 시행하였다. 기저 심근벽 운동의 이상 중 심근벽 운동 이상을 보이는 분절(68분절)에서 심근벽 저운동을 보이는 군(109분절)에서 심근벽 운동의 호전을 보인 심근의 비율은 무운동을 보인 군과 비교하였을 때 의미있는 차이가 없었다(50% 대 41.3%, p=0.26). 자기공명영상의 후기 조영 증강영상에 따른 비교에서는 경색의 심근벽 이환 정도(transmural extent of infarction, TEI)에 따라 각각 TEI grade 0 군에서 60.5%, TEI grade I군에서 58.9%, TEI grade III군에서 51.2%, TEI grade IV군에서 29.4%, TEI grade V에서 8%였으며 이를 경색 정도가 심근벽의 50%를 이환하는 값으로 이분하였을 때 (TEI 50%) TEI가 50% 이하인 군(118분절)은 전체 분절 중 67분절(56.8%)에서 심근 운동의 회복을 보였으며 이는 TEI가 50%를 초과하는 그룹(59분절)의 12분절(20.3%)비하여 의미있는 차이를 보였다(p<0.001). 결론 : 심근경색에서 기저 심근벽 운동의 상태는 심근벽 호전을 예측하는데 도움이 되지 못하였다. 그러나 자기 공명 영상의 후기 조영 증강의 심근벽 이환 정도는 심근 수축력 향상을 예측하는데 유용하였으며 이는 임상에서 치료의 방향을 결정하는데 도움이 될 것으로 사료된다. Background : Cardiovascular MR has recently been reported that it can determine the viable myocardium. We investigated this study to determine the usefulness of cardiovascular MR in prediction of wall motion recovery after revascularization in acute myocardial infarction Methods : Both cardiovascular MR with contrast enhancement and coronary angiogram were performed in 19 patients with acute myocardial infarction who treated with precutaneous intervention or thrombolytic therapy. Six months follow-up angiogram and MR study were also preformed. Thirty two matched segments model of the left ventricle were used to analysis the wall motion change and the grade of transmural extent of hyperenhancement (TEI). Results : Among 628 segments, 177 segments showed wall motion abnormality. In group of segments showing hypokinesia (68 segments), the proportion of segments showing wall motion improvement was not different from that of the akinetic segments group (109 segments) (50% vs 41.3%, p=0.26). The proportion of segments showing wall motion improvement were 60.5% in group of TEI grade 0, 58.9% in TEI grade I, 51.2% in TEI grade III, 29.4% in TEI grade IV, 8% in TEI grade V. If the groups were divided into two according to cut-off value of TEI 50%, In the group of TEI less than 50%, 67 out of 118 segments (56.8%) showed wall motion improvement in contrast with 12 out of 59 segments (20.3%) in the group of TEI above 50% (p<0.001). The status of baseline wall motion abnormality (hypokinesia or akinesia) did not effect on wall motion improvement after revascularization. Conclusions : The baseline wall motion abnormality (hypokinesia or akinesia) did not predict the wall motion improvement. But, TEI grade was significant factor to predict the wall motion improvement.(Korean J Med 69:364-370, 2005)
