RESUMO:  O objetivo deste trabalho consistiu em avaliar a viabilidade econômico-financeira de empreendimentos de construção e demolição realizarem a reciclagem de fragmentos de concreto e cerâmica. Para tal, foram projetados quatro cenários econômicos considerando construtoras responsáveis pela geração de diferentes quantidades de resíduos de construção e demolição (RCD’s), nos quais foi orçada uma britadeira móvel para a reciclagem do material. Os custos relacionados à aquisição, operação e manutenção da britadeira, foram confrontados em fluxos de caixa, com as receitas provenientes do uso ou venda do material reciclado na forma de brita n° 0, bem como da economia com caçambas de entulhos. Posteriormente, a rentabilidade dos projetos foi avaliada mediante o fator de recuperação do capital, o valor presente líquido e a taxa interna de retorno. Quanto maior a produção de RCD’s, maior também é a relação custo-benefício da aquisição da britadeira e, em função da maior quantidade de brita n° 0 reciclada (passível de ser utilizada na produção de contrapiso ou comercializada) e da maior economia com caçamba de entulhos, maiores são as receitas adquiridas, menor é o período de retorno do capital investido e maior é a rentabilidade financeira dos cenários projetados. A reciclagem de RCD’s além de proporcionar benefícios ambientais, pode ser um investimento financeiramente atrativo. ABSTRACT: The objective of this work was to evaluate the economic and financial feasibility of construction and demolition projects to carry out the recycling of concrete and ceramic fragments. For this, four economic scenarios were designed considering constructors responsible for the generation of different amounts of construction and demolition waste (RCD's), in which a mobile squeegee was used to recycle the material. The costs related to the acquisition, operation and maintenance of the crushing machine were compared to cash flows, with revenues from the use or sale of recycled material in the form of gravel No. 0, as well as the economy with litter bins. Subsequently, the profitability of the projects was evaluated by the capital recovery factor, the net present value and the internal rate of return. The higher the production of RCD’s, the greater the cost-benefit ratio of the purchase of the crushing machine and, due to the greater quantity of recycled crushed stone (which can be used in the production of sub-floor or commercialized) and the largest economy with a bucket of debris, the higher are the revenues acquired, the lower the return period of invested capital and the greater the financial profitability of the projected scenarios. Recycling RCD’s in addition to providing environmental benefits can be a financially attractive investment.

The objective of this study was to analyze the influence of the adoption of single-phase and two-phase system on the economic feasibility of tambaqui (Colossoma macropomum) family production in the Tracuateua municipality, Pará state. The operational cost methodology and economic efficiency indicators were adopted to compare these rearing systems. The annual production was 4,200 kg and 5,826 kg. The operational costs were R$ 26,169.00 and R$ 34,365.00, the total operational cost was R$ 27,505 and R$ 35,701.00, and the total operational cost per kg was R$ 6.55 and R$ 6.13 for single-phase and two-phase systems, respectively. Regarding the indicators, the net present value was R$ 24,180.70, the internal rate of return was 24%, the cost-benefit ratio was 1.19, and the capital return period was four years in the single-phase system. In the two-phase period, the net present value was R$ 48,582.06, the internal rate of return was 29%, the cost-benefit ratio was 1.25, and the capital return period was 3.6 years. Despite the demand for greater investment, the two-phase system proved to be more profitable than the single-phase system, promoting even a reduction in unit production cost.

The recovery of an investment is very important in the world of economy. While businesses are preparing long-term projects for investment purposes, basic criteria such as changing economic conditions, risks, cash flows of the project, discount rate to be applied, economic life should be estimated in advance. For this reason, businesses prepare different projects that can provide the same economic conditions for the projects they prepare. In order to compare these projects, a cost-benefit table is prepared and evaluated in terms of their advantages. In line with these values, it is ensured that the most correct project is selected by eliminating each other. In this study, the cost-benefit ratio method was applied to three different projects. For all three projects, 10% annual interest and numerical values between 15 and 60 years of life are given. As a result of the evaluation of the projects, the most suitable project was determined by eliminating each other. Cash flows are calculated based on present and annual equivalents.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

Obesity represents one of the most challenging public health problems of our century. It accounts for approximately 5% of deaths worldwide, mostly owing to cardiovascular disease and its associated complications. Cardiovascular noninvasive imaging may provide early accurate information about hypertrophy and ischemia/fibrosis in obese subjects. Echocardiography and nuclear cardiology have serious limitations in obese subjects owing to poor acoustic window and attenuation artifacts, respectively. Coronary computed tomography angiography can provide information about obstructive coronary disease; however, the use of radiation is a serious disadvantage. Finally, cardiac magnetic resonance (CMR) holds the promise of an “all in one” examination by combining evaluation of function, wall motion/thickness, stress rest/perfusion, replacement and diffuse fibrosis without radiation. Future studies are required to document the cost/benefit ratio of the CMR in the evaluation of cardiovascular risk in overweight/obese children and adolescents.

To the Editor.— Two recent reviews in Pediatrics1,2 provide much interesting information on the effect of home visits on the health of women and children. However, I was disappointed not to find in either article more than token reference to the cost of the programs reviewed. In this day of increasingly scarce health care resources, we no longer have the luxury of evaluating programs such as these without detailed consideration of their cost-benefit ratio.

AbstractThe authors review the main concepts regarding the importance of cleaning/disinfection of ultrasonography probes, aiming a better comprehension by practitioners and thus enabling strategies to establish a safe practice without compromising the quality of the examination and the operator productivity. In the context of biosafety, it is imperative to assume that contact with blood or body fluids represents a potential source of infection. Thus, in order to implement cleaning/disinfection practice, it is necessary to understand the principles of infection control, to consider the cost/benefit ratio of the measures to be implemented, and most importantly, to comprehend that such measures will not only benefit the health professional and the patient, but the society as a whole.

In this paper we explain some of the difficulties of providing forecasts of the financial benefits of early intervention programmes, focussing on those delivered during the early childhood period. We highlight the diversity of early intervention, and the complexity and multiplicity of outcomes. We summarise recent work at the Early Intervention Foundation to assess the evidence on the impacts of early intervention, recognising the diversity of approaches to delivery and the importance of innovation and local practice as well as of rigorous approaches to evaluating causal effects. We also describe new ways of assessing accurately the local fiscal costs of late intervention and consider the implications of this for addressing the well-established barriers to investment in prevention. Our analysis brings to the fore gaps in the evidence from which even the most rigorous ‘gold-standard’ research is not immune. These limitations prevent the production of an accurate and realistic cost-benefit ratio or net present value for the majority of programmes as delivered in practice. We suggest some paths towards a firmer foundation of evidence and a better alignment of evidence and policy.

Improved Technology

The paper has studied the economic viability of improved technology (Introduced under NAIP component-3) for extraction of cashew kernel from cashew nut in Bastar region of Chhattisgarh, India. Cost concept has been used to calculate economics of cashew kernel. The technology (Boiling, steaming, cutting, drying, and peeling) has been found viable over conventional practices (Traditional manual separation by stone or hammer) on account of higher recovery of 40 percent and cost reduction by 29.71 percent. Overall net profit per unit (One unit includes one boiler, one steamer, two cutter, one dryer, six peelers and cost of land, depreciation and interest on working capital) in the case of improved technology has been estimated to be Rs 7.32 lakh. Cost of production in machine extraction practices was 202.80 Rupees per kilogram of cashew in spite of traditionally practiced 288.56 Rupees per kilogram. The cost benefit ratio was found higher in machine extraction (1.57) as compare to traditionally practiced (0.169). The mechanical decortications and separation could not only save time and money, also reduced women drudgery (due to manual breaking by stone or hammer to separate kernel). The technology has been found suitable for promotion of entrepreneurship on the processing of cashew kernel from cashew nut in the production catchments which otherwise is not properly utilized.

Selection Of

The objective is to reinforce the importance of blood reinfusion as a cheap, safe and simple method, which can be used in small hospitals, especially those in which there is no blood bank. Moreover, even with the use of devices that perform the collection and filtration of blood, more recent studies show that the cost-benefit ratio is much better when autologous transfusion is compared with blood transfusions, even when there is injury to hollow viscera and blood contamination. It is known that the allogeneic blood transfusion carries a number of risks to patients, among them are the coagulation disorders mediated by excess enzymes in the conserved blood, and deficiency in clotting factors, mainly the Factor V, the proacelerin. Another factor would be the risk of contamination with still unknown pathogens or that are not investigated during screening for selection of donors, such as the West Nile Fever and Creutzfeldt-Jacob, better known as "Mad Cow" disease. Comparing both methods, we conclude that blood autotransfusion has numerous advantages over heterologous transfusion, even in large hospitals. We are not against blood transfusions, just do not agree that the patient's own blood is discarded without making sure there will be enough blood in stock to get him out of the hemorrhagic shock.

The Impact

Farmers are faced with challenges of producing enough food and the use of traditional methods seems not to keep pace with the ever-growing demand of the populace thus creating increased concern in food scarcity. Although it has been identified that smart tools will enhance the production pace needed in the Agricultural sector, unfortunately, most of these tools are designed for farmers without their inputs, thus creating tools that are not meeting demands. This study focused on a farmer-centered design, development, and deployment approach to improving farm productivity. The design thinking approach was used to identify the specific need of the farmers in selected areas, ideas were created using brainstorming sessions involving experts in the field, and prototypes were developed and deployed to evaluate the impact performance. The result shows that the proposed system improved the cost-benefit ratio of crop farming from 2.14 to 2.26. This is a 12% productivity increase.
