The cost of hospice care should be covered by the insurance system if it is to be promoted in our country and this, in turn, requires a proper method to the estimate of this cost. The purpose of this study was to set up the method to estimate the cost of hospice care. First the cost effectiveness of hospice care were studied. By tracing the activities of hospice nurses for a given period, all the relevant data such as the scope and load of activities as well as the cost were collected. Then these were analysed and compared with the data obtained from hospice and home care. The results showed that the cost of hospice care was the most economic, and indicate its qualification as .1n in-dependent system. The main part of the cost of hospice care was found to be the labor cost which was up to 83% of the total. Therefore a method to estimate the cost should reflect the real labor cost. Several methods have been proposed in the study in terms of unit labor cost, service time, material cost, and the weight of the labor cost. All variables, including the service time surveyed in this study, can easily be translated into numerical values and it would not difficult to estmate the cost of hospice care. Hence by letting the hospice care be insured, hospice care can be expected to function as a good alternative to the present medical system.

Recently, public office building projects are being recognized by many construction engineers and researchers, as the critical projects in the construction industry. The project budgets have sometimes exceeded due to the lack of core knowledge, experiences, skills and experts concerned in cost planning and estimating in the pre-construction stage. It has been highlighted that planning and estimating effectively the cost of public office building projects as critical in the design stage. Within this context, some cost data books and systems, such as RSMeans cost data systems and Spon's price book, have been systematically developed and used by many construction cost managers and organizations in order to effectively estimate and use their project budgets. As a result of this research, a cost estimating model for finishes has been developed, considering the cost data used in public office building projects.

국내 건설산업의 공공 발주자는 사업의 초기단계의 사업비관리에 대한 중요성을 충분히 인식하고 있음에도 불구하고 체계화된 공사비 산정시스템을 보유하고 있지 못한 실정이다. 이에 신규 공공 건설공사를 기획하고 사업비를 책정하는 단계에서는 예산을 수립하는 담당자가 기존의 실적데이터와 경험을 바탕으로 공사비를 추정하고 있으며, 기본설계단계와 실시설계단계 이후 산정된 공사비를 책정된 예산과 비교 후 사업의 추진여부를 검토하거나 설계내용을 예산에 맞도록 변경하고 있다. 이에 본 연구에서는 공공아파트의 사업초기단계에서 공사비를 산정할 수 있는 공공아파트 계획설계단계에서의 공사비 예측모델을 개발하고자 하였다. 본 연구의 결과를 바탕으로 계획설계단계에서 공사비를 예측하고 사업비 및 전반적인 설계를 관리한다면 지금보다 더 효율적인 방법으로 국가의 재원을 적절하게 책정하고 집행할 수 있을 것으로 판단된다.

This paper estimates electrical fire damage cost-effect to analyze electrical safety efficiency by applying a cost-benefit analysis method for analyzing the efficiency of a business public interest. Electrical fire loss statistics data was presented as direct costs and casualties, including deaths due to an electrical fire, this paper adds overhead "Incidental Cost of Accidents to the Employer" by W. H. Heinrich was applied to estimate the cost of economic loss. Also wounded, including the loss of human deaths by referring to the car accident insurance claims costs and human development estimated the losses caused by an electrical fire. And to perform a cost-benefit analysis of the electrical safety as a result of future work. In this paper, the economic effect of the electric field of safety and public interest work to systematically presented.

Construction industries worldwide have moved to Building Information Modeling environment in conjunction with IT technology progress. Korean domestic construction market is in the midst of enthusiastically adopting BIM technique and the public sectors try to apply the method to their projects. Difficulties have been introduced, however, in doing so mainly due to the complexity in reflecting the distinctions of the public cost estimate requirements to BIM modeling. The main objective of this study is to propose four kinds of BIM property information modeling methodologies which would be used in the quantity surveys of the public construction projects. To evaluate the applicability of the suggested modeling methods, the research performed a case study.

Estimating project costs during the early stage of conceptual planning is very important when deciding whether to approve the project and allocate an appropriate budget. However, due to greater uncertainties involved in a project, it is challenging to estimate costs during this initial stage within a reasonable tolerance. This paper attempts to develop a cost-estimate model for public road projects under these circumstances and limitations. In the conceptual planning stage of a road project, there is only limited information for cost estimation, for example, such input data as total length of the route, origin and destination, number of lanes, general geographic characteristics of the route, and other basic attributes. This implies that the model should individuate suitable but restricted information without considering detailed features such as quantity of earthwork and a detailed route of a given condition. With these limited facts, this paper applies a case-based reasoning (CBR) method to solve a new problem by deriving similar past problems, which in turn is used to estimate the cost of a given project based on best-fitted previous cases. To develop a CBR cost-estimate model, the authors classified 8 representative variables, including project type, the number of lanes, total length, road design grades, etc. Then, we developed the CBR model, primarily by using 180 actual cases of public road projects, procured over the last decade. With the CBR model, it was found that the degree of error in estimation can be reasonably reduced, to below approximately 30% compared to the final costs estimated upon the completion of detailed design.

When managers estimate exact construction cost at early stage and design phase, they can reduce construction cost in a more efficient way than to predict at construction stage. But, the current of public construction cost estimation and management is concentrated almost after detailed design phase. Therefore, construction cost management in design development phase to generally use approximate estimating is not correct. Also, the existing construction cost used the method that estimated by gross floor area-based cost estimates at design development phase. So, it is difficult to show the specific amount of materials and basis about the estimated cost of the construction. This study derived problems and limits of construction management at design development phase in case of public office building project through review of literature and current survey, and suggested estimating process model process of structural construction cost go improve these matters.

This study is aimed to get clear model for CM fee level in public construction project. For the practical use and main target, CM for fee contract only is assessed and analysed. Cost estimate by percentage of total contract sum and method based on the historical construction data have significant deficiency. An regression model and probabilistic model are suggested with 9 independent variables. In the case of limited work scope, an element based floor area model is suggested and concluded with fish-bone scheme.

본 연구는 신축 교육시설 프로젝트의 개념단계에서 공사비를 예측하기 위한 인공신경망모델의 제안을 목적으로 한다. 현행 공공 교육시설의 개념단계 공사비예측에는 기본인자인 연면적에 의한 단일변수 모델이 적용되고 있다. 그러나 개념단계에서 단일변수 공사비예측모델을 적용하여 예측된 공사비는 그 오차범위가 크고, 실시설계 완료 후 물량산출에 의해 산정된 상세공사비와 비교하여 큰 차이를 보일 경우 프로젝트의 수정이 불가피하며, 이는 프로젝트의 비용을 증가시키고 공기를 지연시킨다. 그러므로 본 연구에서는 교육시설 프로젝트의 사업계획 수립 및 예산확보 과정에서 공사비예측에 적용이 가능한다 변수 인공신경망모델을 제안하였다. 개발된 모델을 평가한 결과 평균오차율이 6.82%로써, 평균 93.18%의 정확도를 기록하였다. 제안된 인공신경망모델은 지난 5년간 신축된 교육시설의 공사예정금액을 실적자료로 사용하여 학습되었기 때문에, 차후 교육시설 신축공사의 예산편성에 그 활용이 기대된다.

현재 재건축사업은 추진 의사결정과 관련한 확정된 지표나 기준이 없이 막연한 수익성에 대한 기대를 토대로 시행되고 있으며, 사업시행과정 에서 직면하게 되는 제반 위험 에 대해 경험 적으로 대응하고 있는 실정이다. 또한 재건축조합이나 시공예정 회사들이 제공하는 관리처분계획에 포함된 수익성에 관한 정보는 결정론적 분석을 통한 단순한 예측에 불과하여 재건축을 시행하는 과정에서 결과가 수정되는 것이 일반적이다. 즉 수익성에 대한 예측이 재건축시행 과정상의 유동적인 상황에서 변경됨에 따라 예측결과에 대한 신뢰도는 근본적으로 내 외적인 한계를 갖고 있다. 본 연구는 재건축사업의 수익성에 영향을 미치는 변수들을 확률적으로 평가하여 수익과 위험을 동시에 분석하는 수익성예측모델을 개발하고, 사례연구를 통해 개발모델의 적합성을 검증하여 기존의 결정론적 접근방식이 갖는 한계를 극복하고자 한다.
