Method Analysis

The article presents the author’s approach to assessing the risks of corporate and financial security of the region. The purpose of the article is to develop, substantiate and test the author’s approach to assessing and measuring risks of corporate and financial security at the meso-level. The research used methods such as indicative method, comparison method, analysis, synthesis. The paper analyzes conceptual approaches to the concept of security risk, examines the distinctive characteristics of the definition of “risk” from the concepts of “threat” and “danger”. Further, the author examines the issue of the list of main risks in the field of corporate financial security, as a result of which a risk system is proposed that includes 7 main risks, which are assessed using a methodology based on the synthesis of an indicative approach and a minimax method using a normalizing function and a 100-point scale. For each of the risks, indicators are selected, and their threshold values are justified, which are used for comparison with the actual values of indicators, on the basis of which the level of risk is measured. Approbation of the approach proposed in the article was carried out on the example of the Komi Republic. As a result of the risk diagnostics, significant risks of the corporate and financial security of the region were identified, and some recommendations were proposed for solving the problem of improving the conditions for doing business in the region. The obtained results of the work can be used by public authorities in solving the problems of public administration and monitoring the risks of the corporate and financial security of the region.

In account of its abilities to follow the damage progression, also at early stages, the acoustic emission (AE) analysis has become an attractive technique for machine condition monitoring. An AE analysis involves the detection of transients within the signals, which are called AE bursts. Traditional methods for AE burst detection are based on the definition of threshold values. When the machine under analysis works under variable operating conditions, threshold-based methods could lead to poor results due to the influence of these conditions on the AE generation. The present work compares the ability of three AE burst detection methods in a planetary gearbox working under different rotational speeds and loads. The results showed that performance could be significantly improved by using factors of the root mean square value as threshold values instead of fixed values. Among the evaluated methods, the method that includes demodulation and differentiation as a signal processing technique had the best performance overall.

Type Strains

Two strains of gliding, agarolytic bacteria, strains YS10T and YML5, were isolated from coastal seawater off Kamogawa, Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that the novel isolates represent a separate lineage within the genus Flammeovirga. DNA–DNA hybridization values between these isolates and the type strains of species of the genus Flammeovirga were significantly lower than those accepted as threshold values for the phylogenetic definition of a species. Furthermore, some of the phenotypic characteristics indicate that the isolates differ from other Flammeovirga species. Based on these differences, it is suggested that the isolates represent a novel species, for which the name Flammeovirga kamogawensis sp. nov. is proposed. The type strain is YS10T (=IAM 15451T=NCIMB 14281T).

The article determines the list of indicators of the standard of living of the population as a component of social security, including shadow indicators without which the assessment of living standards is inadequate in reality. The authors substantiate the limits of safe existence through the definition of the vector of the indicators’ threshold values. The paper identified the current state of the standards of living in Ukraine, Georgia and Poland through the integrated assessment from the standpoint of security, as well as outlined the most important threats. The researchers also scientifically substantiated the strategic benchmarks for the indicators of the standards of living considering three development scenarios that provide the fulfilment of the established sustainable development goals by means of adaptive regulation methods available in the control theory.

Abstract Background Patient reported outcome measures (PROMs) are increasingly used to monitor recovery paths and the outcome of orthopedic procedures. One of the focus areas is endoprosthetic joint care. Unfavorable post-surgery PROM scores might indicate adverse recovery paths. As of now, an adequate definition of thresholds for recommending an adaptation of therapy does not exist. The same is true for thresholds defining treatment success. Methods To address this research gap, minimal clinical improvement differences and patient acceptable symptom states are estimated using anchor-based methods. Moreover, to better capture the variance in patients' recovery paths, we calculate thresholds for subgroups of patients exhibiting similar pre-operative PROM scores. For this purpose, we use patient data from two German hospitals, covering roughly 6,000 total hip and knee replacement patients treated between 2016 and 2018. Patients answered standard PROM (WOMAC, EQ-5D) and tailored patient satisfaction questionnaires prior to surgery as well as three and twelve months after surgery. Results Whereas we found similar threshold values for total hip and knee replacement patients at the 12 months mark, threshold values after 3 months are systematically better for hip patients than for knee patients. Moreover, we find that thresholds depend on pre-surgery PROM scores. Patients with low pre-surgery scores recover slower, patients in mid-quartiles show large score improvements, and patients in the highest quartile show only mild improvements. Conclusions The study shows that when defining thresholds, it should not only be discriminated by indication but also by patient's pre-surgery condition. This pre-surgery condition can best be described by pre-surgery PROM scores. Further, to implement thresholds into standard care, policy makers need to collaborate with public sickness funds and hospitals to refine thresholds based on nation-wide data. Key messages An adequate definition of PROM score thresholds is necessary to be able to evaluate intervention recommendations and treatment success after surgery. So far, existing research is limited. Recovery paths and therefore PROM score thresholds differ between indications and are dependent on patients’ pre-surgery condition, best described by pre-surgery PROM scores.
