The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

Background: Winding deformation is one of the most common faults in power transformers, which seriously threatens the safe operation of transformers. In order to discover the hidden trouble of transformer in time, it is of great significance to actively carry out the research of transformer winding deformation detection technology. Methods: In this paper, several methods of winding deformation detection with on-line detection prospects are summarized. The principles and characteristics of each method are analyzed, and the advantages and disadvantages of each method as well as the future research directions are expounded. Finally, aiming at the existing problems, the development direction of detection method for winding deformation in the future is prospected. Results: The on-line frequency response analysis method is still immature, and the vibration detection method is still in the theoretical research stage. Conclusion: The ΔV − I1 locus method provides a new direction for on-line detection of transformer winding deformation faults, which has certain application prospects and practical engineering value.

At present, it is so prominent in the development of the petrochemical industry in China,and it is accompanied by petrochemical wastewater, which has become a big problem need to solve urgently.Because petrochemical wastewater mainly contains benzene-compound, organic matter, high salt wastewater and oil sewage, etc. They are very damaging and highly contaminated. The composition and properties of the petrochemical wastewater were introduced firstly, the current situation of petrochemical wastewater treatment at home and abroad were reviewed in the study. Especially the development of petrochemical industry in sichuan was introduced. Based on the present situation and the existing problems, put forward some countermeasures and expect technique develop direction in the future.

Hyperbranched polymers (HBPs) have been applied in various fields because of its outstanding biodegradability and biocompatibility. At present, there are a variety of methods that are used to fabricate HBPs, such as polycondensation, reactive polymerization and ring-opening polymerization according to reaction mechanism. These methods are all environmental-friendly and high-efficient to generate HBPs, and are valuable for industrialization. In this work, we conclude some common methods of HBPs fabrication and make the comparison between them to analyze their advantages and disadvantages, which contribute in how to improve the synthesis process in the future research.

The problems raised in the doctrine of constitutional law related to the implementation of a decision taken in a referendum in matters of particular importance to the state, as well as the generally marginal use of the institution of popular vote in the constitutional prac-tice, give rise to reflection on the introduction of the institution of a referendum law into the Polish constitutional system. In this article the author considers the advantages and disadvantages of such a solution, analyzing at the same time contemporary normative regulations concerning such acts in other countries. The research leads to the conclusion that despite the risks involved, the refer-endum law should appear in the Polish constitutional system in the future, as it would not only give a chance for a more complete reflection of the will of the collective subject of sovereignty without the necessity of its decoding by the parliament, but it could also be an impulse for the development of the referendum practice in the Republic of Poland. However, it is important to introduce proce-dural barriers that will prevent depreciation of this institution.

The article is devoted to the problem of the banks’ participation in improving the efficiency of the organization of cash circulation, which does not lose its relevance in the modern economy. In the current situation, despite the growth in the volume and share of non-cash payments, the demand for cash is characterized by stability. The article focuses on the features, advantages and disadvantages of the reducing cash circulation process. It is noted that the primary impact on cash circulation is made by settlements made by individuals. In this regard, the study focuses on the fundamental changes in this direction that are taking place in the banking sector. This is, first of all, the reduction of cash withdrawals from plastic cards and the growth of non-cash payments with their use, the lack of growth of the card market; increase in electronic terminals and reduce the number of ATMs installed. At the same time, it is emphasized that one of the main areas that determine both the liquidity and profitability of the bank is the regulation of cash balances. With the number of banks operating in the economy shrinking, the struggle for customers is becoming more acute. The satisfaction of the latter with the quality of the bank’s services, including in terms of settlement liquidity, should be considered as one of the primary factors that ensure the effectiveness of a significant number of banking operations. In this context, special attention is paid to the specifics of the bank’s actions to optimize cash flows, which requires the use of specialized automatic systems that allow processing data on cash balances and turnover to form forecasts that optimize the collection schedule and reduce ATM downtime due to lack of funds

This article aims to present a brief review on sensors used for gait detection in Ankle Foot Orthosis (AFO) application. Both the advantages and disadvantages of sensors such as EMG sensor, rotary encoder, foot switches, and force plate are highlighted in this article. Authors also addressed the four characteristics of sensors for gait detection; uniformity, installation, flexibility, and multi-measurement. In addition, the sensors were then compared based on the characteristics. The foot switch was identified as the most compatible sensor for gait detection. However, the sensor was also discovered to contain problems in its durability and uneven grounding. Consequently, the authors propose an introduction to a new material, hybrid Magnetorheological Elastomer (MRE). Coincidentally, the mentioned material possesses attributes of thin dimensions with adjustable stiffness. The thin dimension allows the hybrid MRE to be placed under the AFO sole. Furthermore, with an accurate degree of stiffness, the hybrid MRE allows for adjustment leading to a higher level of durability of the sensors which remains fine even if stomped on the user. In conclusion, the authors propose a further study on hybrid MRE AFO for the next study.

The article includes consideration of the norms on land damage under the criminal legislation of the CIS countries, analysis of approaches to the legal regulation of land protection in criminal legislation. It is determined that not all criminal laws have the special rules protecting the land only. We analyzed the signs of land damage, revealed the specifics of objective signs of land damage, as well as analyzed the advantages and disadvantages of legal regulation in comparison. It is concluded that relations on the protection and rational use of land, ensuring environmental safety are very important for the uninterrupted provision of the population with a sufficient number of safe and affordable products in the future.
