Rural Tourism as an Element of Sustainable Diversification of Economic Opportunities of the Region

The collective monograph «Determinants of Innovation and Investment Development of Multisectoral Entrepreneurship, Tourism and Hospitality Industry» is devoted to the 20th anniversary of the Educational and Scientific Institute of Economics and Law of Cherkasy Bohdan Khmelnytsky National University and is a continuation of the research tradition on the development of entrepreneurship, innovation, finance, competition, accounting and auditing problems, tourism, hotel and restaurant business. The results of the scientific research presented in the collective monograph show the achievements of the representatives of various scientific schools, allow analyzing the experience gained and, considering current economic and political realities, contribute to the scientific substantiation of the prospects for the development of entrepreneurship, tourism industry, hotel and restaurant economy, enrich the intellectual potential of higher schools. The topics of sections and subsections identify the problem issues of innovation, investment and information technology in entrepreneurship, consider the competitive environment in the field of entrepreneurship, investigate the financial-economic and social problems, various directions of tourism industry development, declared by the World Economic Forum jointly with the World Tourism Organization (UN WTO). Particular attention is paid to the development of new trends in the hotel and restaurant business. A common task for scientists, educators, and employers in the conditions of international environmental instability is the formation and dissemination of new knowledge to achieve ambitious goals concerning the entrepreneurship development of tourism, hotel and restaurant business. The proposed discussion of current issues, experience and recommendation exchange will contribute to problem solving, research intensifying in the specified areas of activity. An important component of the modern economics is entrepreneurship; and the intensification of entrepreneurial activity should ensure overcoming of economic crises and their social and economic consequences, and determine the dynamic progress of a society and future welfare of people. It is entrepreneurship that is considered in many economically developed countries as a defining condition for a social and economic prosperity. Entrepreneurial activity involves all branches of economy including industrial, humanitarian and service areas. Therefore, it is necessary to study the key factors for the development of entrepreneurial activity in Ukraine. The current problems of entrepreneurship, tourism, hotel and restaurant business are extensively investigated by both domestic and foreign scholars. A number of researches focuses on these problems. Without diminishing the importance of their contribution to science, the need for further research and improvement should be noted. Therefore, in the monograph, special attention is paid to the state support of business structures, the regulation mechanisms of entrepreneurship, tourism, hotel and restaurant business, social sphere and interaction of market and state institutions, etc. The research was carried out using the developed scientifically substantiated methodological approaches based on the scientific developments of leading foreign and domestic scientists, which allowed proposing the specific directions of entrepreneurship development in the fields of economy, tourism, hotel and restaurant business. The unique nature of the monograph is not only its scientific significance, but also its practical application; since the substantiated positions, measures, proposals for the further transformation of economic processes in Ukraine and in the world have practical value

Promotion sustainable tourism in global economy

Purpose is to substantiate the ways of promotion sustainable tourism in the global economy. Methodology - To determine the importance of the sustainable tourism factors, the hierarchy analysis method of T. Saati was used. The method of expert estimations has been used for determining the significance level of the tourism sustainability factors. Findings - The conditions for promotion of the sustainable tourism to the world market and the factors of impact on its development in the global economy have been determined. All impact factors were divided into 7 groups: political and regulatory environment, environmental sustainability, social and cultural strategy, economic sustainability, tourism service, safety, basic sustainability state. To assess the potential of the sustainable tourism by international destinations, it was offered to rank the factors of index of sustainable tourism development in the countries from the point of view of a tourist. Contribution - The structure of the factors of tourism sustainability index with the emphasis on the role of an immediate tourist was improved. The most importante factors of influence on the choose tourist destination have been identified: the factors of safety, tourist service and the factor of basic sustainability state of a country

Fostering Sustainable Tourism in Global Economy

The study of the essence of the sustainable tourism, transformation of the modern functions of global tourism, rethinking of its basic principles made it possible to form the conceptual framework of the sustainable tourism. The conditions for promotion of the sustainable tourism to the world market and the factors of impact on its development in the global economy have been determined. The technique for calculation of the tourism sustainability index, taking into account the anthropogenic factor, was improved

Exhaust gases heat recovery of GPU gas turbine compressor of gas-main pipelines

The choice of the rational heating scheme of gas turbine exhaust-gas heat utilization of main gas pipeline gas-compressor units is one of the actual problems of increasing energy efficiency of gas transportations. A number of well-known publications state that problem solution can not be considered to be completed, some results of investigation being conflicting and requiring more precise definition, taking into consideration that the processes of converting low potential heat into electric power are considerably complex. The thermodynamic efficiency and various parameter influences are also analyzed. The choice of the plant working-medium at the temperature of exhaust gases of 350-380C is explained in detail

The in-process control of PVC sheath of a double core cable

In this work the possibility of the sheath hermiticity testing by measuring of the cable capacity per unit length variation during spark testing is considered. The research object is 2•0.75 HO3VVH2-F cable. According to the physical modelling it is proved that such defect of sheath as pinhole through the whole thickness of sheath can be registered for the test length 10 cm with test voltage frequencies 1kHz and 10kHz

Determination of sensitivity for in-process control of cable product insulation

This article presents current methods of cable insulation control. The new method which allows to improve reliability of cable insulation control was offered. The cable model with several types of defects was developed by using Comsol Myltiphysics software. Minimal sizes of defects which can be detected by using given in-process control method

Problems of Automatic Test of Insulation in Cable Production

The article presents a qualitative and quantitative assessment of cable products insulation defects that can be reliably detected by means of the electrosparking control during the cable production process. The performance potential of technological control is evaluated: the limit of reliable detection of defective places in insulation taking into account the technical capabilities of modern control devices is marked

Determination of enamel insulation corona resistance by high-frequency modulated pulses

In the article test equipment is described for corona resistance testing of enameled winding wire samples. The primary element of equipment is generator producing test voltage with necessary waveform and magnitude according to the required PWM. Test conditions are accurately simulated by operational loads on a winding insulation (simultaneous impact of temperature and corona discharges). Obtained results of average time to breakdown show that the enamel insulation modified by silicon nanoparticles has a maximum corona resistance
