nical systems. Discussed are the difficulties in estimating and predicting their technical condition, that are caused by the lack of information about regular patterns of random processes of parametric varia-tion, unavailability or lack of information about disturbing effects and the impact of external factors on the ongoing processes. The authors demonstrate feasibility of reducing the method of controlling the operation of unique high-duty technical systems to the decision-making problem under conditions of uncertainty with a guaranteed result. The application of search optimization algorithms that do not use information about the derivatives of optimized functions and allow parallelization of computation-al processes is considered.

The paper focuses on the problem of circuit design of analog technical devices and systems with due account of random processes of changing their parameters and reliability requirements. A functional-parametric approach is used, based on the computer modeling of the systems functioning and changes in their parameters; methods of optimal parametric synthesis under reliability criteria are used to solve it. The paper also discusses the problems caused by the lack of information about the patterns of ran-dom processes of parameter changes, the absence or lack information about disturbing influences, the effect of external factors on the processes within them. The possibility of applying search optimization algorithms that allow parallelization of computational processes, as well as the possibility of using evolutionary calculations with the probabilistic nature of the optimality criterion, the nonlinearity of the objective function and its restrictions are analyzed.

The article discusses the advantages of BIM (Building Information Modeling) technology in the management of bridge infrastructure on mining areas. The article shows the problems with information flow in the case of bridge objects located on mining areas and the advantages of proper information management, e.g. the possibility of automatic monitoring of structures, improvement of safety, optimization of maintenance activities, cost reduction of damage removal and preventive actions, improvement of atmosphere for mining exploitation, improvement of the relationship between the manager of the bridge and the mine. Traditional model of managing bridge objects on mining areas has many disadvantages, which are discussed in this article. These disadvantages include among others: duplication of information about the object, lack of correlation in investments due to lack of information flow between bridge manager and mine, limited assessment possibilities of damage propagation on technical condition and construction resistance to mining influences.

Levels Of Support

Existing research has consistently shown that perceptions of the potential economic consequences of Scottish independence are vital to levels of support for constitutional change. This paper attempts to investigate the mechanism by which expectations of the economic consequences of independence are formed. A hypothesised causal micro-level mechanism is tested that relates constitutional preferences to the existing skill investments of the individual. Evidence is presented that larger skill investments are associated with a greater likelihood of perceiving economic threats from independence. Additionally, greater perceived threat results in lower support for independence. The impact of uncertainty on both positive and negative economic expectations is also examined. While uncertainty has little effect on negative expectations, it significantly reduces the likelihood of those with positive expectations supporting independence. Overall, it appears that a general economy-wide threat is most significant, and it is conjectured that this stems a lack of information on macroeconomic governance credentials.

The Impact

The present research aims to establish the impact that the current crisis situation the planet is facing, namely the COVID-19 pandemic, has had so far on the Romanian labor force market. In this context, given the lack of information and information regarding this pandemic and its effects, the administration of a questionnaire among the population was considered to identify the research results. The method of semantic differential and the method of ordering the ranks were used for the interpretation of the results. With the help of this questionnaire, it will be possible to answer the question of the research in this study: What are the main effects of the COVID-19 pandemic on the Romanian labor market? The main results showed that the COVID-19 pandemic affected the Romanian workforce; the respondents of the applied questionnaire claimed that they obtained better results and maintained a similar income, but the health crisis also influenced the mentality of employees, with respondents stating that in the event of changing jobs, they would consider it very important for the new employer to ensure the conditions for preventing and combating COVID-19, as well as complex health insurance. However, analyzing at the macroeconomic level, it was found that the COVID-19 pandemic induced an increase in the number of unemployed people in the Romanian labor market.

The Impact

The research presented in the article, which includes methods, models, and conclusions, contains synthetic and analytical model solutions concerning the problems of the technical maintenance and wear of residential buildings with a traditional construction. The cause and effect relationships between the occurrence of damage in the elements of tenement houses (treated as proof of their maintenance conditions), and the size of the technical wear of these elements were determined using a representative and purposefully selected sample of 102 residential buildings erected during the second half of the nineteenth and early twentieth centuries in Wroclaw’s “Downtown” district. Quantitative damage analysis, which was carried out using empirical (visual) methods of assessing the technical condition of a building, indicates the type and size of damage to the building’s elements that are characteristic for the relevant maintenance conditions. Research concerning the cause–effect relationships (“damage–technical wear”) in observed states allows for a numerical approach to the impact of building maintenance conditions on the degree of the technical wear of its components. The maintenance and exploitation conditions determine the degree of the technical wear of the elements of an old residential building. The exploitation condition of these buildings is manifested by damage to elements caused by water and moisture penetration, which is especially important for poorly maintained buildings. The article shows that the age of the elements of an old residential building with a traditional construction is of secondary importance in the process of the intensity of losing its serviceability value. It was calculated that no more than 30% of the damage of building components is explained by the passage of time, and it is therefore not age that determines the course of the technical wear of the elements of the analyzed tenement houses.

<p>The term competitiveness is a relative concept whose perception changes with the level of conducted analysis (nation, sector, company). Thus, a variety of internal and external factors can have deep effects on the competitiveness of a given entity. This paper aims to evaluate the competitiveness of Moroccan exports by identifying the main determinants that explain their performance. This is particularly dealing with the impact of customs’ tariff, the tariff of import, foreign demand, the share of the non-residents in the capital of domestic enterprises and the investment rate compared to the value of exporters.</p><p>Moreover, this paper presents a literature review on competitiveness and examines the main results of our econometric analysis regarding the determinants of export competitiveness applied to the top ten branches most exporters in Morocco. The gained results allow confirming the sensitivity of exports by branch to the situation of Morocco’s main trading partner namely the European Union while emphasizing, quantitatively, on the role played by the investment effort undertaken by Moroccan exporting companies in improving the competitiveness of national exports.</p>

Objectives: To analyze the impact of steroids on postoperative tonsillectomy recovery and implement findings for improvement in postoperative management. Methods: Institutional review board approved prospective study with retrospective analysis of private practice setting tonsillectomy patients (November 2015 to January 2017). A questionnaire was provided postoperatively to patients undergoing tonsillectomy with or without adenoidectomy. The study population was separated into 2 groups: patients who received steroids (3 days of either dexamethasone or prednisolone), postoperative steroid (POS), versus patients who did not receive steroids (PONS). Results: The questionnaire had a return rate of 27.3% (254/931). Nine of the 254 responses were disqualified for lack of information; therefore, the total number of responses was 245. Of these, 115 were POS and 130 were PONS. The groups were similar in mean age (POS: 13.2 ± 10.4 years, PONS: 14.7 ± 12.1 years, P = .32) and sex (POS: Male 40.0%, PONS: Male 40.0%, P = .97). There was an overall decrease of pain and nausea/vomiting (N/V) in the steroid group ( P = .0007). There was reduction in pain ( P < .05) from postoperative day (POD) 2, 3, 4, and 6 in the POS group. Otherwise, there was no significant reduction in pain from POD 7 to 14, day-by-day rate of N/V, bleeding, or rate of emergency department (ED) or clinic visit ( P > .05). Conclusion: Postoperative steroid reduced overall pain and N/V, as well as daily pain on POD 2, 3, 4, and 6. Pain from POD 7 to 14, rate of ED or clinic visit, or daily N/V and bleeding rate were not significantly different between cohorts.
