기존에 수행된 연구에서는 혼합구조보의 구조적 특성을 결정할 수 있는 제 영향인자 중에서 주근의 정착방법, 전단스팬비의 변화, 이질구조부의 보강 유무, 보강 방법의 변화 등에 따른 일련의 연구 성과들을 발표하였으며, 이러한 결과를 바탕으로 본 연구에서는 이질구조부에 대한 응력전달 및 내력상승 측면에서 철골단면적에 대한 인장철근비(철골철근비)를 변화시킨 단부 RC 중앙부 SC조 혼합보에 대해 RC부 주근의 정착방법(플랜지위 직접 용접, 스터드볼트 용접정착)에 따른 구조적 거동 특성을 고찰하였다. 그 결과 주근의 정착방법에 따른 구조적 특성은 거의 나타나지 않았으며, 철골철근비가 증가함에 따라 내력면에서는 효율성을 기대할 수 있으나, 연성능력이 저하될 수 있으므로 혼합구조보의 구조적 특성을 극대화시키기 위해서는 적정한 철골철근비로 제한하는 것이 필요한 것으로 나타났다. In the preceding study, a series of results was presented according to factors like as attaching method of main bar, shear span to depth ratio, reinforcing method for different types of region among various factors, which could determine the properties of composite beams. Based on these results, this study was planned to investigate the structural behaviors of according to attaching method of main bar for composite beams(end-reinforced concrete(RC), center-steel concrete (SC)) varying ratio of tensile bar to steel mainly. Consequently, there were little difference according to attaching method of main bar. And as the ratio of tensile bar to steel increase, the efficiency of strength was high, but ductile capacity of beams could deteriorate. Therefore, to maximize the structural properties of composite beams, it was considered that the ratio of tensile bar to steel should be limited.

The purpose of this study is to draw the calculating indexes of city capacity and apply in practice. The 30`s indexes as the primary calculating indexes of city capacity were chosen from the 750`s indexes. The 12`s final indexes including ``air clearness`` were selected by a survey on the experts. And then the weights of the indexes were calculated by the AHP(Analytic Hierarchy Process). The analysis showed that in upper hierarchy, the weight of infrastructure category was 0.515, that of environment category was 0.319 and that of culture-finance category was 0.166. In subclassification, the weight of public transportation capacity was 0.118 and it was the highest among the indexes. Finally, this study drew the capacities of the 7`s metropolis in Korea based on the indexes and weights. The process of analysis consisted of data reduction, data standardization and calculating city capacity. It is expected that this study will give a clue to planning related to ``Green City`` and ``Energy Saving City``.

This study was performed to analyze the distribution characteristics of facilities located in the central business district of Daejeon metropolitan city. This research analyzed the agglomeration and dispersion, and the contiguity for 36 facilities in the region‘ This study estimated the average spatial distances of the 36 facilities. In addition, the 36 facilities were classified into similar types using a statistical analysis method, MDS(Multidimentional Scaling). The results of this study are summarized as follows; The facilities for shopping goods such as bedclothes, precious metals, cosmetics, and accessories, showed the accumulative distribution pattem while those for convenience goods such as coffee shops, drugstores, convenience stores, laundries and beauty salons, exhibited the dispersive distribution pattem. From the contiguity an머ysis, the facilities for shopping goods such as precious metals, cosmetics, and accessories were found to have the spatial similarity, representing that the average spatial distance from one facility to another is close. In addition, food and beverage facilities such as coffee shops, bars, and restaurants and convenience facilities such as beauty salons, convenience stores, and laundries, were analyzed to have higher contiguity relative to other types of facilities.

Purpose: The purpose of this study was to report on the results of performing modular cementless total hip arthroplasty with a simultaneous subtrochanteric shortening osteotomy in patients with high hip dislocation. Materials and Methods: We evaluated 23 patients (24 hips) with high hip dislocation and who had undergone total hip arthroplasty using a proximally modular cementless stem in combination with a subtrochanteric shortening osteotomy in order to place the acetabular cup at the level of the anatomic hip center between May 1996 and June 2008. There were 6 males and 17 females with a mean age of 44 years. The mean duration of follow-up was 5.6 years. Results: The mean Harris hip score improved from 53 points preoperatively to 88 points at the time of final followup (P<0.001), and there were good or excellent results in 21 hips (87.5%). There was one instance of isolated loosening of the acetabular component. With the exception of one hip requiring revision surgery at 12 years postoperatively because of polyethylene wear and cup loosening, all the remaining components were well-fixed at the time of the last follow-up. A total of 4 hips (17%) had complications during follow-up; one dislocation, two transient femoral nerve palsies and one nonunion of the subtrochanteric osteotomy site. Conclusion: Modular cementless total hip arthroplasty with a subtrochanteric shortening osteotomy in patients with high hip dislocation was associated with excellent clinical outcomes while it minimized additional fixation of the osteotomy site.
