본 연구는 유능한 민간투자 사업시행자를 선정하기 위한 절차모델을 제안한 것이다. 국내$\cdot$외 문헌과 기존 방식 및 제도에 대한 검토$\cdot$분석을 통하여 국내 민간투자 사업시행자 선정 절차의 현황과 문제점을 파악하였다. 적격심사 및 협상절차의 불합리, 사업 참여주체 간 의사소통$\cdot$정보교환 기회 부족 등 문제점을 도출하였으며, 각각의 문제점들에 대한 대안을 모색하였다. 면담조사 및 설문조사$\cdot$분석을 통하여 국내 실정에 적합한 대안을 설정하고 기존의 절차를 혁신한 새로운 사업시행자 선정모델을 제안하였다. 사전자격심사(PQ)제도의 시행, 사업계획 평가 및 협상 절차의 개선, 민간의 창의와 효율성 도입, 의사소통 및 정보교환의 활성화를 촉진할 수 있는 내용을 선정절차에 포함하였다. 또한 전체 사업시행자 선정이 객관적이고 투명한 환경에서 이루어 질 수 있도록 사업시행자 선정 Team의 구성$\cdot$운영을 제안하였다. The purpose of this study is to suggest a systematic procedural model for selecting competent project promoter. The proposed model was made by comparing domestic regulations and procedures with foreign nations', and through interviews with experts and literatures survey. The summaries of this paper are as follows. The current promoter selection procedure was evaluated by reviewing relevant papers, regulations and existing model. Some obstructions which hinder PPI project activation were identified, those are inadequacy of promoter qualification and negotiation process, lack of communication between parties, etc. Some alternatives which remove major obstructions are embodied in the model. The suggested model is comprised of PQ(prequalification), two phased evaluation for the technical proposals which include alternate, communication meeting, etc. To manage the overall procedure well, an involvement of professional "project promoter selection team" would be highly recommended. They will participate in each evaluation stage with full activities, and provide government with some technical materials for selecting promoter as coordinator.

목적 : CT영상 에서 Metal Artifact는 영상 진단정보를 얻는데 지장을 초래한다. 이러한 Metal artifact를 감소시킬 수 있는 Program인 PHILIPS사 iQon 장비의 SBI Data 영상과 O-MAR Data 영상을 정량, 정성적 비교 분석 하고 SBI Data의 Energy level 중 영상이 왜곡 되지않고 진단이 용이한 이상적인 영상을 획득할 수 있는 Energy level을 찾아보고자 하였다. 대상 및 방법 : 2016년 7월1일부터 2017년 1월31일까지 고려대학교 안산병원을 내원하여 슬개골 골절, 인대손상, 경골골절 및 감각이상으로 CT 검사를 시행한 환자 중 금속 인공물 시술이나 수술을 받은 20명을 대상으로 하였으며 환자의 평균 연령은 46.3세, 남·여 비율은 남성 14명, 여성 6명으로 PHILIPS사 의 O-MAR Reconstruction, SBI Reconstruction 기법을 적용하여 데이터를 획득하였다. 스캔 변수는 관전압 120kVp, 관전류 120mAs, Pitch 0.391, Thickness 3mm, Rotation time 0.4 (sec) 검사하였다. 결과 : 측정결과는 Knee joint Conventional data 영상의 SNR 평균값은 7.79, CNR 평균값은 19.09, 평균HU값은 312.93 평균SD값은 45.86 O-MAR data SNR 평균값은 1.72, CNR 평균값은 3.79, 평균HU값은 188.75, 평균SD값은 147.03 SBI data Energy level (40-200KeV) SNR 평균값은 16.77, CNR 평균값은 22.65, 평균HU값은 76.22, 평균SD값은 15.84로 측정되었다. 결론 : 본 연구에서는 Conventional 영상보다 O-MAR 영상이 Metal Artifact를 감쇠시키는데 효과가 있었다. 그렇지만 Soft tissue를 보상시 영상 재구성 과정에서 왜곡이 발생하였다. 그에 비해 SBI data 영상은 Energy level를 조절하며 Metal Artifact를 감쇠시키고 soft tissue, bone의 왜곡이 적은 영상을 동시에 획득할 수 있다는 면에서 진단적 가치가 있었다. Purpose : In the CT images, the Metal artifact causes disruption in imaging diagnosis. The study analyzes SBI Data images and O-MAR Data images of IQon CT (Philips) that reduces metal artifact, the study finds ideal Energy level that not have distortion of images for diagnosis among Energy levels of SBI Data. Object and method : The study is targeted 20 peoples (The mean age - 46.3 years / The sex ratio - 14 males and 6 females) with the knee arthroplasty surgery of patellar fracture, ligament injury of knee, tibial fracture – who examined the IQon CT scan from July 1, 2016 to January 31, 2017. The study acquired the data was applied O-MAR Reconstruction, SBI Reconstruction technique. The scan parameter is 120kVp, 120mAs, Pitch 0.391, Thickness 3mm, Rotation time 0.4 (sec). Result : The SNR average value of the Knee joint Conventional data images is 7.79, the CNR average value is 19.09, HU average value is 312.93 SD average value is 45.86 the SNR average value of the O-MAR data images is 1.72, the CNR average value is 3.79 HU average value is 188.75 SD average value is 147.03 the SNR average value of the SBI Data 16.77, CNR average value is 22.65 HU average value is 76.22 SD average value is 15.84 Conclusion : In the study, the O-MAR image is effective to reduce the Metal artifact than conventional images. But, it was distortion of image reconstruction of soft tissue. On the other hand, the SBI data image is less distortion of image of Metal, soft tissue, bone to control Energy level.

Since「the Act on Private Participation in Infrastructure(PPD)」was established in 1998, a number of projects have been procured by private-sector-initiatived system for infrastructure development. However, there are many shortcomings in the procedure of selecting project promoter for the domestic-PPI projects due to deficient regulations, lack of investment appetites, necessary skills and experiences, etc. An improved promoter selection procedure is necessary to select a competent project promoter and to foster participation of the private party. The purpose of this study is to suggest a procedural model for selecting competent project promoter. This model was made by comparing our regulations and procedures with foreign nation's. The suggested model is comprised of PQ, two phased evaluation system for proposals. To manage the overall procedure well, an involvement of professional "project promoter selection team" would be highly recommended.

Since 『the Act on Private Participation in Infrastructure(PPI)』 was established in 1998, a number of projects have been procured by private-sector-initiatived system for infrastructure development. However, there are many shortcomings in the procedure of selecting promoter for the domestic-PPI projects due to deficient regulations, lack of investment appetites, necessary skills and experiences, etc. It is required to improve the methodology and procedure which selects a competent promoter to foster participation of the private party, activate PPI project. The purpose of this study is to suggest a adequate method select promoter by comparing the domestic selection method with the foreign nation'. The suggested method is focused on the PQ and proposal evaluation. As a result of comparative study, the multi-phases evaluation method included alternative proposal should be adopted in the proposal evaluation procedure to select a qualified promoter.

The purpose of this paper is to develop a risk analysis method using fuzzy theory for construction projects. Construction risks are generally evaluated as vague linguistic value by subjective decision making. Fuzzy theory is a proper method to quantify vague conditions of construction activities. Therefore, this study utilizes fuzzy theory to analysis construction risks. Risks are identified and classified into two levels such as upper level risk factors and lower level risk factors by RBS(risk breakdown structure). The risk exposure of lower level risk factors is assessed using fuzzy inference individually and their absolute and relative weights are estimated by fuzzy measure and AHP respectively. The estimated risk exposures and weights are aggregated to assess the risk exposure of upper level risks by Choquet fuzzy integral.
