최근 국내 VE에 관한 이슈가 대두되고 있으며, 이에 따른 연구가 활발히 진행되고 있다. 하지만 기능분석 및 VE분석절차에 관한 연구에 머물러 있을 뿐이고, 합리적인 제안 채택을 위한 연구는 미흡한 실정이다. 이에 본 연구에서는 특히 발주자의 입장에서 실행단계 업무처리와 VE활성화에 일조할 수 있도록, VE프로세스에서 제안채택 여부를 결정하는 최종단계의 평가 절차와 기준에 관한 체계적인 방안을 제인하고자 한다. 우선, 국내외 문헌고찰 및 설문조사를 통하여 문제점을 파악하고 개선방향을 도출한다. 이어서 제안채택 여부 결정을 위한 세부절차를 설정하고 표준평가쉬트를 제안하였다. 마지막으로, 본 논문은 프로젝트의 성격에 따라 발주자 측에서 적절히 조정하여 적용한다면 VE관리업무에 효율적으로 활용될 수 있을 것으로 기대된다. The role and importance of VE have been enlarged since VE application was mandatory by law in public sector in March, 2000. Public organizations have widened the technological horizon through VE competitions and applied VE technique to private investment projects. Many studies have been carried out on function analysis and VE procedure. In practice it is common that clients make a decision one-sidedly on whether or not VE proposals are selected. The VE procedure itself is not smooth. This study gives some suggestions on VE appraisal procedure and criteria at the last phase on VE process in order to smooth the progress of VE. The results of this study can be used as a tool to improve efficiency in the management of VE.
Random Urinary Calcium/Creatinine Ratio for Screening Hypercalciuria in Children with Hematuria
최인수,정의석,Young Earl Choi,조영국,양은미,김찬종 대한진단검사의학회 2013 Annals of Laboratory Medicine Vol.33 No.6
Background: Hypercalciuria is one of the most common causes of unexplained isolated hematuria. The diagnostic methods for hypercalciuria have not yet been standardized. The aim of this study was to assess whether random urinary calcium/creatinine ratio could be used as a screening tool for hypercalciuria in children with hematuria. Methods: This prospective study included 264 children with primary hematuria for whom both random and 24 hr urinary evaluations were performed. Pearson correlation and ROC curve were used to assess the correlations. A multiple linear regression model was used to analyze effects of age, weight, height, body mass index, and body surface area on random urinary calcium/creatinine ratio. Results: There was a moderately strong correlation between random urinary calcium/creatinine ratio and 24 hr urinary calcium excretion (r=0.584, P<0.001). The most appropriate cutoff value of random urinary calcium/creatinine ratio for the estimation of hypercalciuria was 0.075 mg/mg (sensitivity, 77.8%; specificity, 64.3%; area under the curve, 0.778). Body mass index and 24 hr urinary calcium excretion significantly affected random urinary calcium/creatinine ratio with a low coefficient of determination (r2=0.380, P<0.001). Conclusions: Random urinary calcium/creatinine ratio is not suitable for screening hypercalciuria in children with hematuria. Twenty-four hour urinary analysis should be performed to diagnose hypercalciuria in children with hematuria.
슬관절 전치환술 시행 후 CPM과 PNF 치료에 따른 효과 비교
최인수,배성수,Choi, In-soo,Bae, Sung-soo 대한고유수용성신경근촉진법학회 2004 PNF and Movement Vol.2 No.1
Objective : Compare the results of CPM and PNF in recovery rates when applied as an initial physical therapy. Methods : Randomly selected 19 patients who underwent through total knee replacement surgery. 23 cases were studied and divided into 12 CPM and 11 PNF cases. CPM case was carried out for 60 minutes, a maximum allowed exercise without pain. PNF case was carried out for 20 minutes by a therapist to a patient as 'one on one'. Result : Result showed that PNF treatment was increased significantly at P<0.05 in flexor muscle strength in 8 days after the surgery. Conclusion : The study revealed that in comparison with CPM, PNF was more effective treatment increase of flexor muscle strength in rehabilitation on after total knee replacement surgery.
유한 크기 효과를 고려한 비선형 의존성 지표를 활용한 계층적 리스크 패리티 모형 기반 포트폴리오 최적화
최인수 ( Insu Choi ),김우창 ( Woo Chang Kim ) 한국정보처리학회 2023 한국정보처리학회 학술대회논문집 Vol.30 No.2
본 연구는 계층적 리스크 패리티 (Hierarchical Risk Parity, HRP) 포트폴리오 방법론과 정규 화된 상호 정보 거리의 결합을 연구하였다. 이때, 한정된 이동창에서 발생할 수 있는 유한 크기 효과(finite size effects) 문제를 극복하기 위해 무작위로 섞인 NID 값에 대한 평균치를 제공함에 따라 NID 를 활용한 새로운 포트폴리오 최적화 방법을 제안한다. 본 연구의 결과는 NID 를 통합한 HRP 포트폴리오가 기존 방법론에 비해 통계적 장점과 함께 더욱 효율적이며 안정적임을 보여준다.
