In general, the present value (PV) concept is ambiguous. Therefore, behavioural factors may influence on the PV evaluation. The main aim of our paper is to propose some method of soft computing PV evaluated under the impact of behavioural factors. The starting point for our discussion is the notion of the Behavioural PV (BPV) defined as an imprecisely real-valued function of distinguished variables which can be evaluated using objective financial knowledge or subjective behavioural premises. In our paper, a BPV is supplemented with a forecast of the asset price closest to changes. Such BPV is called the oriented BPV (O-BPV). We propose to evaluate an O-BPV by oriented fuzzy numbers which are more useful for portfolio analysis than fuzzy numbers. This fact determines the significance of the research described in this article. O-BPV may be applied as input signal for systems supporting invest-making. We consider here six cases of O-BPV: overvalued asset with the prediction of a rise in its price, overvalued asset with the prediction of a fall in its price, undervalued asset with the prediction of a rise in its price, undervalued asset with the prediction of a fall in its price, fully valued asset with the prediction of a rise in its rice and fully valued asset with the prediction of a fall in its rice. All our considerations are illustrated by numerical examples. Presented examples show the way in which we transform superposition of objective market knowledge and subjective investment opinion into simple return rate.

The Mayten tree (Maytenus boaria Mol.), a native plant of Chile that grows under environmentally limiting conditions, was historically harvested to extract an edible oil, and may represent an opportunity to expand current vegetable oil production. Seeds were collected from Mayten trees in north-central Chile, and seed oil was extracted by solvent extraction. The seed oil showed a reddish coloration, with quality parameters similar to those of other vegetable oils. The fatty acid composition revealed high levels of monounsaturated and polyunsaturated fatty acids. Oleic and linoleic acids, which are relevant to the human diet, were well represented in the extracted Mayten tree seed oil. The oil displayed an antioxidant capacity due to the high contents of antioxidant compounds (polyphenols and carotenoids) and may have potential health benefits for diseases associated with oxidative stress.

Abstract Background Antibiotics (AB) are administered for medical prophylaxis (MP) to prevent infectious complications. The second national point prevalence survey (PPS) of healthcare-associated infections and AB use was conducted in Italy in 2016-2017. The survey found MP accounted for nearly 25% of all registered ABs, more than twice the EU/EEA proportion. The aim of this study was to evaluate how many ABs were administered for MP and how frequently general indications were followed. Methods Data from the PPS were used to evaluate the prevalence of indications for MP over the total number of ABs, the proportion - among these indications - of those justified by a motivation in the patients' charts, and the prevalence of ABs considered appropriate for MP. The evaluation was made in 12 hospitals out of 14 participating in the PPS in Piedmont, chosen on the basis of patient traceability. According to national guidelines, the indications for MP that were considered appropriate in this study were: Trimethoprim/sulfamethoxazole for P. carinii pneumonia, Rifaximin for diverticulitis, Penicillin for Streptococcal infections and for splenectomized patients, and Rifampin for TB infections. Results 1844 AB prescriptions were registered among 1334 traceable inpatients in Piedmont. The prevalence of indications for MP was 16.2% and 253 ABs (84.6%) were prescribed with a motivation. Only 3% of ABs registered as MP were appropriate for this indication: Bactrim 2%, Rifaximin 0.3%, Penicillin 0.2% and Rifampin 0.4%. Conclusions This study found an extremely high rate of inappropriate ABs for MP, that will be further investigated through qualitative analysis of medical records to evaluate whether a misunderstanding of the PPS protocol occurred and empirical therapy was confused with MP. Nevertheless, this study highlighted the need for interventions to improve prescribing appropriateness for MP. Key messages This study found that only 2.98% of ABs registered as MP among traceable patients in Piedmont were appropriate for this indication. 15.38% of prescriptions for MP were not justified by a motivation. Interventions to improve prescribing appropriateness for MP could lead to a considerable reduction in inappropriate use of ABs, which is crucial in a country facing hyperendemic levels of AMR.
