  • In the architectural design process, the selection and configuration of the structural system significantly affect the earthquake behaviours of the reinforced concrete buildings. The main purpose of this study, the effects on the earthquake performances and the rough construction cost of the buildings of the slab type in reinforced concrete buildings are to examine comparatively for different local soil classes. The results obtained from this study have been determined that the building model having slabs with beams is safer compared to other types of slabs, especially when considering the vertical bearing structural elements (columns). It also shows that other types of slab, except for slab with beams, reduce the earthquake performances of reinforced concrete buildings, increase the displacement values, 1st natural vibration period values and the cost of rough construction. This matter reveals that slab type is quite important and the preference of beamed slabs in reinforced concrete buildings to be constructed in earthquake zones would be more appropriate in terms of safety and cost.

  • Consumer's demand level for products and goods selection power is considerably improved. The pressure of loss compensation is also being accelerated by products which bring damage on property. The producer prevents the loss from causing poor products and considering the quality cost allotment in these circumstances. That is to say, producer should be concerned with the strategy of product liability prevention instead of passive defence policy. This paper intends to estabilish the optimum quality cost in considering product liability, and present the correlation of quality cost elements and multiple regression analysis. It can utilized in qualitycost and budget planning.

  • This paper presents brief history and a state-of-the-art survey of Life Cycle Cost (LCC) analysis, in particular LCC analysis in the Urban Transit Vehicle, based on a internationl codes and standards related to LCC analysis. A main objective of the LCC analysis is to quantify the total cost of ownership of a product throughout its full life cycle, which includes research and development, construction, operation and maintenance, and disposal. The predicted LCC is useful information for decision making in purchasing a product, in optimizing design, in scheduling maintenance, or in planning overhaul. This paper presents a LCC procedure consisting of seven steps, which are "Problems definition", "Cost elements definition", "System modeling", "Data collection", "Cost profile development", "Evaluation", and "Verification". Sub-activities to be encompassed in the seven steps procedure are described.

  • Sustainability is becoming more and more important in our everyday lives. Thus, it is apparent that more sustainable initiatives are incorporated in a building design concept to reduce operation costs and environmental impacts. However, will the construction cost go up if the building is going green - especially if it is a tall building? This is the question on everyone's mind. In the following paragraphs, we will look into a case study of a skyscraper in Nanning, China. That 411-metre skyscraper, Nanning China Resources Centre East Office Tower, is currently under construction. Designed to LEED-CS Gold standards, the building has adopted a number of sustainable design elements and operation practice, which indeed only accounts for a small percentage of the total construction cost.

  • Recently the power system consists of the more complicated structure, due to increase of power demands. In this circumstance, the congestion and loss capacity in transmission line is also increased. Accordingly, the investment planning of transmission system is required to reduce the congestion and loss of the transmission line. This paper proposes a method to compute the congestion and loss costs which are the key elements in economic assessment of the power system planning. And the benefit of market participants in CBP (Cost Based Pool) is computed. To demonstrate the efficient of the suggested methods, these methods are applied to peak load system of 2016 in the 4th Basic plan of Long-Them Electricity Supply and Demand.

  • The sudden changes in the construction market and the progressively intensifying price wars have amplified the importance of the construction cost estimation in the initial and planning phases of construction projects. However the methodologies and process of estimating construction cost in the planning and design phase are not standardized in the domestic market, in contrast to the markets of more developed countries. Therefore this paper proposes a new approximate estimation model to be used from the initial stages of construction projects. This methodology that extracts, modifies and synthesizes comparable elements of previous cases. This will introduce the foundation for the implementation of systems with improved usability and applicability.

  • The purpose of this research is to determine elements affecting the out-of-pocket cost of woman. The sample consisted of 1907 women living Iksan city. The survey was conducted by means of questionnaires. The model used in the analysis of out-of-pocket cost was the Andersen-Newman model, while the analysis techniques used were stepwise multiple regression and path analysis. The number of independent variables used in the analysis was 28 in total, ie 19 predisposing components, 6 enabling components, and 3 need components. In this study, the amount of variance by the model was 17 percent. Number of restricted activity days caused by oral disease, perceived susceptibility of dental disease, having a regular dental care, dental treatment costs, education level and income were found to have significant major effects on out-of-pocket cost. Number of restricted activity days caused by oral disease was the most important variable affecting out-of-pocket cost of woman. Also out-of-pocket cost shows larger effect due to enabling components than frequency of dental utilization.

  • Purpose: This study focused on analysing costs per home health care nursing visit based on home health care nursing activities in medical institutes. Method: The data was collected in three stages. First, the cost elements of home health care nursing services were collected and 31 home care nurses participated. Second, the workload and caseload of home care nursing activities were measured by the Easley-Storfjell Instrument(1997). Third, the opinions on improving the home health care nursing reimbursement system were collected by a nation-wide mailing survey from a total of 125 home care agencies. Result: The cost of home health care nursing per visit was calculated as 50,626\. This was composed of a basic visiting fee of $35,090{\\}({\fallingdotseq}355$)$ and travel fee of $15,536{\\}({\fallingdotseq}15$)$. The major problems of the home care nursing payment system were the low level of the cost per visit, no distinction between first visit and revisits, and the limitations in health insurance coverage for home health care nursing services. Conclusion: This study's results will contribute as a baseline for establishing policies for improvement of the home health care nursing cost and for applying a community-based visiting nursing service cost.

  • The term 'cost reduction' often carries a negative image in a sense of sacrifice of other management elements such as qualify, safety, client satisfaction, etc. However creative cost reduction approaches can achieve not only cost reduction itself but also value for money. The objective of this paper is to identify and discuss major characteristics of creative cost reduction strategies from best practice cases of Constructing Excellence.

  • TRL has a direct impact on development schedule and cost in the system or technology development projects. If TRL capability of development organization for specified CTEs can be accurately assessed and the impact of TRL on development schedule and cost are analyzed as detailed as possible, the risk of development schedule delay and cost increase can be minimized during the development process. This paper describes analysis results of TRL impact on development schedule and cost in the aerospace project. The development schedule and cost change are quantitatively estimated for the TRL improvement in the Unmanned Aerial Vehicle(UAV) system development program.
