  • INNOVATIONS – PREREQUISITE FOR PENSION SYSTEMS ADEQUACY

    • Authors: Ivanka Daneva
      Pages: 7 - 20
      Abstract: The paper examines the views of Bulgarian and foreign researchers on the essential characteristics of the pension system adequacy and its modern characteristics. Adequacy is highlighted by financial security and equivalence in pension insurance. A definition of adequate income in the form of a pension is proposed. The main exogenous factors characterizing the need for modern innovations in the pension system have been characterized. The main directions in which the changes in the pension insurance models are taking place are defined. It is argued that in every modern state the generosity of the social security system is predetermined by the relative effectiveness of the alternative to the pay-as-you-go system.

  • ASSESSMENT OF RELATIONS BETWEEN RENEWABLE ENERGY AND ECONOMIC GROWTH IN
           BULGARIA - VAR ANALYSIS

    • Authors: Hamit Can, Gabriela Krasteva
      Pages: 51 - 61
      Abstract: The role of existing interconnections between renewable energy on the one hand and economic growth on the other is an emphasis on many studies, but within the scope of Bulgaria, the specificity of these relations requires an in-depth review of the growing importance of renewable energies. The main factors to be surveyed are: consumption of renewable energy, production of renewable energy and per capita GDP. The interaction of these variables is analyzed to show the direction and importance of the relationship. The analyzes include the vector autoregression model and a number of cointegration and causality tests. The period covers the years after the collapse of the socialist system and the integration of modern energy use, as well as the specific crisis moments that changed and reduced the prospects for sustainable growth, part of which are also the alternatives for the extraction of natural energy resources.

  • THE ECONOMIC INSTRUMENTARY OF THE "SOFT POWER" IN THE
           INTERNATIONAL ECONOMIC RELATIONS

    • Authors: Zlatka Kushelieva
      Pages: 77 - 82
      Abstract: "Soft power" is a complex instrument of international politics. It is an organized set of interactions and relationships predetermined to a large extent by the psychological element. Its core qualities are attraction, persuasion and legitimacy. The "soft power" acts in international relations through a complex instrumentation consisting of actions in the military, political, economic, cultural, sports, ideological, religious spheres, but all its manifestations must be supported by the economic instrument. To this end, many countries have set up special bodies. It is expected that "soft power" will be a major instrument of international politics in the coming epoch.

  • EUROPE IN THE MULTIPLE WORLD OF THE 21ST CENTURY

    • Authors: Zlatka Kushelieva
      Pages: 83 - 88
      Abstract: The development of the process of globalization during the transition period from the 20th to the 21st century imposed a new socio-political and cultural differentiation. Countries are no longer isolated, they are no longer autonomous in the satisfaction of their political interests. They are interconnected and interdependent. In addition, it has moved from a bipolar to multipolar world system. The European Union has a special role to play in it. It is the only regional organization that not only preserves but also expands. It also guarantees citizens peace, freedom, high quality of life, which creates a particular appeal to the world's society. Naturally, he has also been subject to crises, such as the debt crisis, UK leaving and the temporary successes of national anti-European parties and movements. Resisting these crises enables him to achieve a higher degree of integration, relying on the solidarity of member states and citizens of the Union, uniting all European countries and peoples from the Atlantic to the Pacific, including Russia.

    • Authors: Natalia Stoyanova, Dean Monev
      Pages: 89 - 98
      Abstract: The management of human resources is one of the most important activities for the modern organization. The availability of human resources is an essential prerequisite by which organizations can develop. The object of the management of human resources in an organization are the people. They perform the set tasks and pursue the common goals of the organization. The people themselves are very important for the success and development of the organization. These are different people with different abilities, skills, interest, character, temperament, emotional events, needs, attitudes, values, culture, marital status, personal problems and destinies, collected in one place, united by the idea to achieve common goals and good results and thus to contribute to the development of the organization.

  • RESEARCH ON THE IMPACT OF WATER TRANSPORT ON ENVIRONMENTAL QUALITY

    • Authors: Tatiana Zhekova, Maria Daneva, Doychin Nikov
      Pages: 121 - 129
      Abstract: European transport policy emphasizes the development of maritime transport and inland waterway transport. The key components are two - reducing the congestion of road and rail infrastructure and air pollution. They are developed through the establishment of transport links and inland waterway services and more efficient port services. The growth of port transport services also has a significant impact on the environment, which is accompanied by the need to build strategic, evolving ports. This research explores some aspects of sustainable port development and proposes a guideline for the expansion of the Water Transport Simulation Subsystem, which is part of the Unified Ecological System of Navigational Water Areas, with the aim of accurately forecasting the construction of ports required for their sustainable development.

  • EFFECTIVENESS OF SOME PATHOGENIC CONTROL AGENTS AGAINST PESTS IN
           GREENHOUSE VEGETABLE CROPS

    • Authors: Vinelina Yankova, Dima Markova
      Pages: 131 - 138
      Abstract: Greenhouse tomato and cucumber are attacked by a great number of pests. The most frequently occurred pests are: greenhouse whitefly (Trialeurodes vaporariorum Westw.), cotton aphids (Aphis gossypii Glov.), tobacco and western flower thrips (Thrips tabaci Lindeman, Frankliniella occidentalis Perg.), cotton bollworm (Helicoverpa armigera Hb.) and two spotted spider mite (Tetranychus urticae Koch.). Plant protection products applied in practice are not always efficient enough due to arising of resistance to these products in the populations. Moreover their use could results in accumulation of residual amounts and environmental pollution. Recently a great interest to find alternative solutions for pest control is observed. Some viruses, bacteria and fungi which are pathogenic to the pests but safety for human, could be used. There are products with good efficacy, which are developed on this basis and applied for pest control.Investigations for determining of the biological activity in the following products were carried out during the period 2016-2017 in the “Maritsa” Vegetable Crops Research Institute - Plovdiv: Naturalis (a. i. Beauveria bassiana strain АТСС 74040) at a dose of 100 ml/da, Rapax (a. i. Bacillus thuringiensis subsp. kurstaki strain EG 2348) at a dose of 100 ml/da and Helicovex (a. i. Helicoverpa armigera nucleopolyhedrovirus Hear NVP, DSMZ-BV0003 – 7,5 x 1012 NPV/liter) at a dose of 20 ml/da. The product Naturalis at a dose 100 ml/da has a good effectiveness (over 75%) against greenhouse whitefly, cotton aphids, thrips, and movable forms of the two spotted spider mite in tomato and cucumber grown under greenhouses. The products Rapax at a dose of 100 ml/da and Helicovex at a dose of 20 ml/da have a good biological activity (E = 76,32% and E = 76,92%, respectively) towards to the larvae of the cotton bollworm in greenhouse tomatoes.

  • MATHEMATICAL MODEL FOR THE PROSPECTION OF OPTIMAL HUMIDITY IN AGRICULTURAL
           LAND IN NORTH EAST BULGARIA

    • Authors: Pavlina Naskova
      Pages: 139 - 147
      Abstract: Determining the optimum field humidity is time-consuming and costly direct measurement procedure. This is the reason why to focus efforts on developing and approving mathematical models to predict optimal field humidity based on the rainfall from the previous two months.The model presented is based on a multiple linear correlation between three variables. Data on the total rainfall (mm) for July and August 2016 were used at six points for the measurement on Eastern Bulgaria territory, as well as data on productive soil humidity in the layer between 0-20 cm. Established is the existence of a linear dependence between the parameters, the correlation coefficient is determined, the high value of which proves the dependence between the parameters considered under the specific conditions.

  • MATHEMATICAL MODEL FOR EVALUATION OF THE CONTENT OF HEAVY METALS IN SOIL
           BY INDIRECT PLANT SIGNATURES

    • Authors: Pavlina Naskova
      Pages: 149 - 160
      Abstract: The level of ecological science is currently characterized by a high development of the experimental part, which leads to the presence of rich factual material and lesser development of the theoretical base, etc. mathematical ecology, which is limited to the use of a small number of lesser related theories. This determines the need to direct efforts in developing and approving of models for recognizing and forecasting environmental processes and phenomena. The paper presents a mathematical model for assessing the content of heavy metals in the soil by indirect signs of plants. Research on the effectiveness of the recognition procedures has been carried out, depending on the number of status classes and the volume of training data. It was found that in three of the classes of state, the nonlinear algorithm gives better recognition, and with increasing the volume of the learner sample the recognition efficiency increases.
