The purpose of the article is to develop a methodology for alternative substantiation of financial support for bridge construction. To achieve the purpose, the following general scientific and special methods and techniques of research were used: “golden ratio” rule; systematization and generalization; generalization of the results of the analysis and the logical generation of conclusions. Initially, the article analyzed the state of bridge structures in Europe and Ukraine. Based on the analysis, a disappointing situation has been identified, namely that a (...) significant ratio of bridges number require major overhaul or are in critical condition. During the research, the following tasks were solved, namely: physical wear of the bridge as a failure was considered; the feasibility of investing in reconstruction or new bridge construction was determined. For the purpose of rational use of financial resources, which are limited in the age of economic challenges, and on the basis of the rule of “golden proportion”, the maximum percentage of investment in reconstruction is determined. If the limit is exceeded, it is decided to build a new bridge. This result allows making an economically sound decision and evaluating the effectiveness of the invested resources. It is proved that if the wear index of the overhaul bridge construction is higher than the wear rate of the new bridge construction by λ2 / λ1, and the amount of funds for overhaul reaches 70% of the funds needed to build a new one, it is better to build a new bridge.

Communication problems not only every year arouse more and more interest among people of different ages, diffrent professions and education, but, above all, are a necessary component of the professional competence of specialists in all areas of their activity. In 1941, Fethullah Gülen, an Islamic scholar and Turkish public figure, said that "thanks to advances in communications and transport, one of the driving forces of globalization, the distances between countries and peoples are rapidly blurring". But during communication, a person commits (...) many mistakes and stupidities. Foolishness is visible in those moments when a person should be silent, and he speaks, or when it is necessary to speak, and he is silent, - Zufar Fatkudinov said. The same thing happens in entrepreneurial communications. Business communications are a set of contacts in the business environment that each firm establishes and reproduces in the process of carrying out entrepreneurial actions, participation in business relations. Business communications are interfirm or intrafirm in nature. Business communications should be distinguished from ordinary communication. They represent ways of organizing the interaction of business entities with their intra-firm and inter-firm environment, during which all parties of the interaction strive to defend their interests in business. The materials of this book can be used in the study of the disciplines "Ethics of business relations", "Business communication", "Psychology of business communication", "Psychology of management" in higher and secondary educational institutions. The textbook is practically oriented: at the end of each chapter there are control questions and tasks, as well as literature for independent study. (shrink)
