For the Amazon, it is important to encourage the production of native fish, since there are several species of zootechnical interest. For this, it is necessary to know the species since its acquisition, production, processing, and marketing. Therefore, the aim of this study was to analyze the yield, correlations, and profitability of different cuts of black pacu (Colossoma macropomum) in five weight categories. Data from 220 black pacus were obtained, with a weight range of 2725 ± 1975 g. Yields of commercial cuts and morphometric measurements were evaluated in five weight classes. Kruskal–Wallis test (α = 0.05) was used to compare the average income. And, to verify the correlation between the morphometric measures and the yields, Spearman’s correlation was performed (α = 0.05). To obtain the profit of the weight classes due to the cut produced, an economic analysis was carried out considering the cost of buying the fish. Yields of fillet, ribs, and steak were higher in classes 3 and 4, while in the same classes, the yield of residues was the lowest. Despite classes 1, 2, and 5 showing lower yields, the economic analysis presented that the production of fillet and ribs was profitable. The measures of total length and standard length have a high positive correlation with the yield of meat in all classes, as well as the average circumference and caudal circumference in classes 1, 2, and 4, which can be used to determine the yields of this commercial cut.

ABSTRACT Peanuts are one of the high economic value commodities in the dry land area. This commodity also contributes to the social life of the dry land area. This research has been conducted in Semau Sub-district, Kupang Regency, with the aim to determine the amount of income, break event point (BEP), R / C ratio, efficiency of capital use and factors that affect the income of peanuts farming, with the number of farmer respondents as many as 92 people , simple randomly selected. Data that has been collected by survey, library and interview methods; analyzed quantitatively-descriptive using regression methods. The results showed that the total average income of peanut farming in the study location was IDR 1,739,895 with a total average income of IDR 3,498,261 and a total average cost of IDR 1,758,366. While the break event point average of production is 147 Kg and the break event point price is IDR. 6.509, while for the total average the R / C ratio is 1.99. With factors that affect income are production (X1), seed costs (X2), and labor costs (X3). From the regression results with the Cobb-Douglass function the coefficient of determination (R2) is 0.822 with the meaning that variations in independent variables such as production, seed costs and labor costs explain the dependent variable namely income (Y) of 82.20% and the rest 17.80 % is explained by variables outside of the variables analyzed. From the results of the F test (diversity test) it was found that the factors X1, X2, and X3 had a significant effect on income at ⍺ 1%, then accept H1 at least one of: βi ≠ 0. Whereas the results of the t test (partial test) obtained that factors significant effect on income, namely production (X1) and labor costs (X2), while the cost of seeds (X3) does not significantly affect income.

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.

Abstract:An economic evaluation of a medical checkup center (Ninngendokku, “human dry dock”) was conducted from two perspectives: the cost for cancer checkup, and the cost for medical treatment after a diagnosis was obtained. We studied the cost of diagnosing cancer, compared with the cost required when cancer of an individual organ was detected through mass health testing, and studied the economics of a Ninngendokku according to Kawai’s method of medical judgment. Assuming that the cost of death is more than the cost of saving the lives of persons who undergo the Ninngen-dokku, the Ninngen-dokku will be affordable. In the group undergoing the Ninngen-dokku compared with the group which did not, the estimated cost of medical treatment was reduced. The Ninngendokku carries advantages that cannot be quantified in financial terms; therefore, a multi-layered economic analysis of the Ninngen-dokku was required.

This article of the topic is due to the fact that accounting for the cost and financial management system of the enterprise is currently of particular importance and is carried out in a strict manner. When conducting accounting, the following procedures are used: search for compliance of the company's data on accounting and the regulatory framework; study of documentation; finding and forming errors during the audit. Such meth-ods are solved by the rules: evaluation of arithmetic operations; monitoring of inventory; analysis of cash flow in the enterprise; notification of certain persons about the completed economic and accounting operations; interviewing employees orally; assessment of cash flow according to documents; implementation of economic analysis aimed at studying the movement of funds of the enterprise.

To the Editor.— I was delighted to see Donn's letter about the cost effectiveness of home management of bronchopulmonary dysplasia.1 Such contributions are vital in helping to curb the rapidly rising costs of neonatal intensive care. However, his economic analysis is flawed. By tacit assumption, he omits any consideration of the opportunity costs to the parents. To omit this presumes that the parents' time is worth little or nothing, as we often seem to indicate by the long patient waiting times in our offices.

The Canadian Coordinating Office for Health Technology Assessment (CCOHTA) published an economic analysis, using a Markov model, of infliximab therapy for Crohn’s disease that is refractory to other treatments. This was the first fully published economic analysis that addresses this treatment option. Health state transitions were based on data from Olmsted County, Minnesota, health state resource profiles were created using expert opinion and a number of assumptions were made when designing the model. The analysis was rigorous, the best available efficacy and safety data were used, state-of-the art sensitivity analyses were undertaken and an ‘acceptability curve‘ was constructed. The model found that infliximab was effective in increasing quality-adjusted life years when offered in a variety of protocols, but it was associated with high incremental cost utility ratios compared with usual care. The results should be interpreted, however, in view of a number of limitations. The time horizon for the analysis was short (one year), because of a lack of longer-term efficacy data, and might have led to an underestimation of the benefits from averting surgery. Because the analysis was performed from the perspective of a Canadian provincial ministry of health, only direct medical costs were considered. Patients with active Crohn’s disease are likely to incur significant indirect costs, which could be mitigated by this medication. The analysis should be updated as new data become available. Moreover, small changes in the cost of the medication could make the treatment cost effective, according to this model. Economic analyses, such as the one undertaken by the CCOHTA, cannot by themselves solve dilemmas in the allocation of limited health care resources, and other considerations must be included when formulating policy. This is especially important for patients with severe Crohn’s disease, who have significant disability and for whom few therapeutic options exist.

ABSTRACT Methionine is an essential amino acid, and generally, the first limiting one in the diets of tambaqui, the main native fish produced in continental aquaculture in South America. However, there is a lack of information on their amino acid requirement, especially for maintenance and efficiency of utilization. The present study aimed to determine the requirement of [methionine plus cystine] for the maintenance and efficiency of utilization using tambaqui of different body weights. Two experiments were carried out using 250 tambaqui with weights of 100 and 300 g. They were distributed in a completely randomized design with four treatment groups (0.264, 0.396, 0.528, and 0.660% of digestible [Met + Cys]), five replications. The control treatment (CT) was performed with the addition of methionine at the first level (0.264%) until the second level was reached (0.396%). The maintenance requirement was determined by the regression analysis between the consumption of [Met + Cys] and protein retention equal to zero. The efficiency was determined using the value of the slope coefficient of the line obtained by the linear regression. The protein and methionine retention values of tambaqui weighing 100 to 300 g were compared by the parallelism test, and no difference was observed between the parameters of the equations indicating the need for only one equation to describe the responses to body weights. The requirement of digestible [Met + Cys] for the maintenance of tambaqui with weights from 100 to 300 g was 60.47 mg kg-0.7 day-1 and the efficiency of utilization of 42%.
