Published: April 2020

The article is devoted to the improvement of control systems for wind turbines by developing fuzzy controllers with higher transient characteristics and low computational costs of identification in comparison with the applied PI controllers. Based on the self-organization method, a fuzzy speed controller of the doubly-fed induction generator (DFIG) of a wind turbine was synthesized, which uses a zero-order Sugeno fuzzy inference system and is made in the form of a block-oriented Wiener model. This regulator is an element of the vector control system of the transistor converter on the rotor side. The results of simulation modeling of the fuzzy controller showed that it provides a lower transition time compared to the PI controller, by 53.59% during acceleration and by 79.76% during braking, and 23.81% less error speed deviations from the reference signal. Such indicators can minimize losses while maintaining the maximum output power point of the power plant. The implementation of the developed system on wind turbines contributes to increasing the efficiency of wind farms, reducing the cost of electricity production, reducing the payback period of equipment, and the sustainable development of alternative energy in general.

Published: April 2020

Sustainable development of construction materials is directly related to research on the processes of hydration of binders. Builders need better types of cement, with lower cost and energy consumption in production. The development of spin chemistry methods allows us to consider the processes of hydration and structure formation of binders from the spin state of the elements involved in chemical reactions. Magnetic interactions have a significant effect on the spin dynamics and the control of the spin multiplicity of radical pairs. The practical implementation of magnetic effects on a binder can be carried out in various ways. However, a long-term impact can be achieved only by introducing ferromagnetic substances into the binders. In the paper presented the results of a study of the influence of the characteristics of finely dispersed powdered ferromagnetic additives on the strength characteristics of cement. Ferromagnetic additives regulate the behavior of the reactants during rotation during the hydration of the binders due to magnetic interactions and control the reactivity of the chemical reaction. A comparative analysis revealed that it is most expedient to use as powdery ferromagnetic additives are the waste from mining and processing enterprises of the Krivorozhsky field. The work investigated the magnetic and dispersed characteristics of 12 different dust. The experiments showed that the origin of dust and the method of their capture are determined their magnetic characteristics. Preparation of samples with the dust and determination of the strength characteristics of cement were carried out by standard methods. The results obtained made it possible to reveal the laws of the effect of the dispersed and magnetic properties of various dust on the degree of activation of binders.

Authors: Panayotov Vladko , Panayotova Marinela , Chukharev Serhii
Published: April 2020

The inherently law capacity of the classically used carbon-based anode is one of the major drawbacks hindering the wide application of lithium ion batteries (LIBs) in electric vehicles. Carbon replacement with materials possessing high theoretical capacity, such as germanium (Ge) represents one of the approaches used for ensuring wider LIBs’ implementation. The main disadvantage of the Ge use is its huge volume change during the lithiation / delithiation, causing Ge-based electrodes pulverization, deterioration of the electrochemical properties and resulting in electrodes relatively short life. Usage of Ge based nanomaterials is regarded as powerful tool for overcoming the mentioned drawbacks. This paper reviews and discusses the very recent progress in the preparation and studying the Ge nanoparticles (NPs), Ge nanoalloys and Ge-based nanocomposites as attempts for preparation of advanced anodes for LIBs.

Published: April 2020

The risk management of a centralized pharmacy network identifies the research object. The paper proposes a strategy of complex diversification for the pharmacy network. By constructing portfolio models for complex diversification and solving relevant multicriteria problems, multiple pareto-optimal portfolios have been found for successive risk management. Based on the fundamentals of Markowitz portfolio theory and multicriteria optimization, this paper builds four models of the optimal portfolios for centralized pharmacy network. In contrast to the classic two-criteria model (risk minimization while maximizing income), our models have been introduced to maximize entropy, which enhances the diversification effect. Matlab software has been developed for solving multicriteria problems. Model verification was performed on real data provided by one of the pharmacy networks. The modeling results will be useful for automating the business processes of any trading network, managing risk, analysing loyalty programs to improve the effectiveness of their operations.

Authors: Makazan Yevheniia , Los Vita
Published: April 2020

Human capital is a key factor in the success of any enterprise. Since human capital, like other types of capital, is prone to exposure to various types of risk and an important task of any enterprise is to assess the level of human capital. This paper proposes the author’s approach to the formation of the structural components of human capital. Its structure included three sets of indicators that characterize educational, intellectual and physical capital. Also, a methodological approach is proposed to evaluate the human capital level of machine-building enterprises, which consists of three interrelated stages. The methodological approach is based on a point evaluation of the indicators included in the human capital structure based on the questionnaire (polling) of the personnel of the analyzed machine-building enterprises. The assessment of the level of human capital was carried out separately for two groups of workers. It is established that the total value of the integral index of human capital corresponds to the average level for all examined enterprises and ranges from 0,463 to 0,585. It has been found that the personnel at the machine-building enterprises have a great potential for development and a high propensity for change. The advantage of human capital assessment on the basis of its structural components is the ability to determine the optimal need for human resources and forecast the cost of supporting and developing human capital.

Many studies are devoted to the peculiarities of building the information society in the modern world and the problems of uneven development of information and communication technologies in developed and developing countries. This paper examines the influence of the information and communication technologies development on the social and political activities of modern society. The correlation and regression analysis has been used to identify the relationship between the Information and Communication Technology Development Index (ICT), the Human Development Index (HDI) and the Democracy Index (DI). The results demonstrate that there is a close link between the countries’ sociopolitical attractiveness and the level of their information and communication development. However, it is not equal for different countries, which are grouped by the level of ICT, HDI and DI. Besides, the country’s information and communication technologies level has a significant effect on the social and political development. The development of the information component immediately leads to improvement of the socio-political sphere in countries with high levels of HDI, DI and ICT. The EU countries belong to this cluster. Democracy development and ICT have the inverse relationship in the group of countries with average HDI, DI and ICT levels.

Published: April 2020

The article is devoted to solving the problem of evaluation and selection of investment projects aimed at developing territorial communities, taking into account the concept of sustainable development. The problem of choosing from possible alternative solutions is not easy for decision makers and requires qualified justification. This is especially important in the context of decentralization reform, advancement of Ukraine towards society openness, increase of transparency requirements to the authorities and their results. Decision making on the basis of the sustainable development concept determines the evaluation of investment projects in terms of their effectiveness in solving problems of social, economic and environmental nature, finding a balance between these components. The peculiarity of the assessments is not so much quantitative as qualitative character, which makes it expedient to use the apparatus of fuzzy logic. The fuzzy model of evaluation of investment project aimed at developing a territorial community is constructed and substantiated in the work. The model is based on quantitative and qualitative evaluations of the social, economic and environmental components of the concept and enables a “soft” – qualitative evaluation of the investment project under consideration. Modeling results are based on the method of deciding on the choice of investment projects for the development of territorial communities. The proposed model and method are implemented by the Fuzzy Logic Toolbox application, were applied to substantiate decisions for the territorial community of Zaporizhzhia region, and can be used in the development of decision support systems to quantify the decisions and variant calculations.

Authors: Ocheretin Dmytro , Los Vita , Kucherova Hanna , Bilska Olha
Published: April 2020

To date, the country’s business climate characterizes the state of economic development and the results of its effectiveness. One of the key indicators that determine the business climate is the business confidence index (BCI). The paper proposes an approach to modeling the business climate of the country, which is based on the principles of information transparency, and makes it possible to assess the development trends of the studied indicator. The proposed approach is based on the taxonomy method, which allows one to identify the measure of influence of each factor included in the model and exclude the influence of the subjective assessment of the researcher. This approach has been tested on the example of Ukraine. The quarterly values of socio-economic indicators for the past twelve years (2008-2019) were taken as input data. Based on the correlation analysis, from the generated array of incoming data, only those indicators were selected that have a significant relationship with the business confidence index. It has been established that the GDP annual growth rate and retail sales have the greatest impact on the business confidence index. A forecast has been built for the trend of changes in the business confidence index (forecast accuracy of 87.55%), which proves the similarity of development trends in the country’s business climate. The results obtained make it possible to analyze the cyclical development of the country’s economy with high accuracy and reliability.

Published: April 2020

The article proposes two methods for evaluating the financial efficiency of a business model of industrial enterprises. In order to evaluate the financial efficiency of the business model of an industrial enterprise, a system of single indicators for assessing the financial condition of the enterprise by such components as financial stability, liquidity and solvency, business activity and profitability was formed. Fishburne’s rule weights the major components of an integral measure of an enterprise’s business model financial performance. In addition, an integral measure of the financial performance of the business model is modeled using the fuzzy set method and taxonomic analysis, which will help to evaluate the financial performance level of the business model more objectively. The comparative analysis of the obtained results by different methods of calculation of integral indicators is carried out.

Anatomy is one of the basic and very important subject studied by medical students at the beginning of their medical career. Best method for learning anatomy is by dissection of human cadavers and this forms an indispensable part of training health care professionals. Since the numbers of medical institutions are increasing, there is an increased demand of cadavers for anatomic dissection. Body donation is an act of donating one's body after death for medical research and education. In this article an attempt has been made to collect literature related to body donation, its importance and the ethical issues related to body donation.

Delirium is extremely common in intensive care unit (ICU) patient due to comorbidity, critical illness and iatroogenesis. This complication of hospital stay is extremely hazardous in older persons and is associated with prolonged hospital stays. yet ICU nurses and physicians are usually unaware of the presence of hypoactive delirium and only recognize this disturbance in agitated patients (hyperactive delirium).The aim of the study was to assess the existing knowledge of ICU staff nurses regarding ICU delirium and to assess the effectiveness of structured teaching programme on the knowledge of ICU staff nurses regarding ICU delirium. An evaluative approach with one group Pretest Posttest design was used for the study. Fourty samples were selected by using non-probability purposive sampling method, in selected hospitals of Udupi District. The collected data were analyzed using descriptive and inferential statistics. A significant difference between Pretest and Posttest knowledge was found (t=23.95, p=<0.0001). The study findings showed that there significant increase in posttest knowledge of ICU staff nurses regarding ICU delirium. The nurse can identify the delirium early and prevent the complication by treating well in advance.

Individuals with special health care needs experience poor oral hygiene and periodontal status and are more likely to have unmet dental needs than any other medical needs. The study was conducted to assess the views, attitudes and perceptions of oral health and treatment needs among the parents of 250 children with disabilities at 3 special schools in Mangalore based on questionnaire method. Data collected were subjected to statistical analysis.

The educational status of the parents were assessed and it was seen that more than 50% of the parents had school education of class 10 and below. 52% of the parents felt that dental treatment is not as important medical treatment and 69 % of the parent's preferred general dentist and only 12.3% had consulted Pedodontist for any dental needs of their children. Only 11% followed a regular dental check-up and 57% of the parents interviewed visited dentist only when required. 30% of the parents reported lack of awareness as the greatest barrier faced by them in rendering dental care for their children.

There was a generalised lack of information regarding oral health and treatment needs seen among the parents of the children with special health care needs. The level of knowledge appeared to be low and the parents were not aware of the unique problems faced by these children.

The development of red blood cell (RBC) isoimmunization with alloantibodies and autoantibodies complicate transfusion therapy in multiply transfused thalassemia patients. We conducted a study to analyse the frequency in our population. Clinical and antibody profile from 55 multiply transfused thalassemic patients who were receiving transfusions were collected and analyzed prospectively. A commercially available 3 cell antigen panel was used for the antibody screening procedure. If antibody screening with the 3-cell antigen panel was positive, an extended 11-cell antigen panel was used for antibody identification in LISS (Low Ionic Strength Solution). All patients received blood matched for only ABO and Rh (D) antigens. A total of 55 transfusion dependent â thalassemics were included in this study out of which 30 (54.55%) were males and 25(45.45%) females with a male to female ratio of 1.2: 1. Frequency of red cell alloimmunization in this study was found to be 1.8%. None of the patients developed red cell autoimmunization. The alloantibody identified in the the patient who developed alloimmunisation was was anti-K. In conclusion, the transfusion of matched blood is essential for chronically transfused beta thalassemia patients in order to avoid alloimmunization.

Human being ingests a large number of living microorganisms, predominantly bacteria. Although these organisms are naturally present in food and water, they can also be deliberately added during the processing of foods(1). For several decades now, bacteria called Probiotics have been added to some foods because of their beneficial effects on human health. Several clinical studies have already demonstrated the effectiveness of certain probiotics in the treatment of systemic and infectious disease such as diarrhea, crohns disease, cardiovascular diseases, oropharyngeal infections and cancers(2)

Potential application of probiotics for oral health has recently attracted attention of several teams of researchers. The concept of probiotics therapy has been considered for application in oral health. Dental caries, periodontal diseases and halitosis are among the oral disorders that have been targeted. Hence, this section gives a brief idea of probiotics and its application in oral health.
