With the fast development of the fifth-generation cellular network technology (5G), the future sensors and microelectromechanical systems (MEMS)/nanoelectromechanical systems (NEMS) are presenting a more and more critical role to provide information in our daily life. This review paper introduces the development trends and perspectives of the future sensors and MEMS/NEMS. Starting from the issues of the MEMS fabrication, we introduced typical MEMS sensors for their applications in the Internet of Things (IoTs), such as MEMS physical sensor, MEMS acoustic sensor, and MEMS gas sensor. Toward the trends in intelligence and less power consumption, MEMS components including MEMS/NEMS switch, piezoelectric micromachined ultrasonic transducer (PMUT), and MEMS energy harvesting were investigated to assist the future sensors, such as event-based or almost zero-power. Furthermore, MEMS rigid substrate toward NEMS flexible-based for flexibility and interface was discussed as another important development trend for next-generation wearable or multi-functional sensors. Around the issues about the big data and human-machine realization for human beings’ manipulation, artificial intelligence (AI) and virtual reality (VR) technologies were finally realized using sensor nodes and its wave identification as future trends for various scenarios.

Background: The overflow valve, as an essential pressure control element, is widely applied in various hydraulic transmission systems because of its characteristics of constant pressure overflow, stable pressure, system unloading and safety protection. The research on the structure and working principle of the overflow valve are beneficial to improve the working efficiency and operating stability of pressure control of the hydraulic transmission. Therefore, the development trend of the overflow valve for pressure control has been paid more and more attention. Objective: To meet the growing demands for the working efficiency and operating stability of hydraulic transmission, the structure of the overflow valve for pressure control such as direct-acting overflow valve and pilot-operated overflow valve is being improved continuously. Methods: This paper retraces various current representative patents relative to the structural device of direct-acting overflow valve and pilot-operated overflow valve for pressure control. Results: Through investigating a large number of patents on the overflow valve for pressure control, the main current existing problems such as low working efficiency and poor operating stability are summarized and analyzed. Moreover, the development tendency of the overflow valve for pressure control in the future is also discussed. Conclusion: The optimization of the structure of the overflow valve for pressure control is conducive to improve working efficiency and operating stability. More correlative patents will be invented in the future.

The article examines the epistemological roots of conservative ideology, development trends and further prospects in political reform not only in modern Russia, but also in other countries. The author focuses on the “world” and Russian conservatism. In the course of the study, the author illustrates what opportunities and limitations a conservative ideology can have in political reform not only in modern Russia, but also in the world. In conclusion, it is concluded that the prospect of a conservative trend in the world is wide enough. To avoid immigration and to control the development of technology in society, it is necessary to adhere to a conservative policy. Conservatism is a consolidating ideology. It is no coincidence that the author cites as an example the understanding of conservative ideology by the French due to the fact that Russia has its own vision of the ideology of conservatism. If we say that conservatism seeks to preserve something and respects tradition, we must bear in mind that traditions in different societies, which form some kind of moral imperatives, cannot be a single phenomenon due to different historical destinies and differing religious views. Considered from the point of view of religion, Muslim and Christian conservatism will be somewhat confrontational on some issues. The purpose of the work was to consider issues related to the role, evolution and prospects of conservative ideology in the political reform of modern countries. The author focuses on Russia and France. To achieve this goal, the method of in-depth interviews with experts on how they understand conservatism was chosen. Already today, conservatism is quite diverse. It is quite possible that in the future it will transform even more and acquire new reflections.

This article is devoted to the studying hermeneutic circle in the development of methodological culture of future music teacher. Under the conditions of globalization processes, tendencies of convergence of world cultures improvement of culturological training of student youth requires new approaches, in particular, culturological training of students of pedagogical specialties. The task of pedagogical education is to develop a teacher as a specialist and as a person of high culture, who has a special positive effect on the personality of school student. This article analyses the works of scientists dedicated to the issues of establishment and development of the hermeneutic approach in philosophical, psychological, and logical and gnosiological contexts. It is defined the essence of the concept of “hermeneutic circle” as one of the basic principles of the hermeneutic approach. There have been provided the examples of interpretation of the principle of hermeneutic circle by various scientists. Hermeneutic approach is applied in sciences such as pedagogy, psychology, economics, sociology etc. In pedagogical science the hermeneutic approach at the level of conceptual use was elaborated by A. Zakirova. She introduced the term “pedagogical hermeneutics”. Hermeneutic circle as a principle of text understanding is based on the interrelation of the part and the whole. Understanding of the whole consists of the understanding of the individual parts, and understanding of the parts requires understanding of the whole. The concepts of the part and the whole are correlated: the text is a part concerning the whole creative activity of the author, which in its turn is a part of the particular genre or literature in general, as well as the part of spiritual life and biography of the author. The idea of hermeneutic circle means also that there is no understanding of the text without certain prerequisites: understanding is preceded by some idea of what is yet to understand. There have been determined the peculiarities of the use of the principle of hermeneutic circle in the development of methodological culture of the future teacher of musical art. In light of hermeneutical trends, the penetration of which in the realm of musical art can be traced quite clearly, the use of the hermeneutic circle principle in the development of methodological culture of the future teacher of musical art appears not only in the narrow interpretation of the particular phenomenon or group of phenomena, but much wider — as a means of learning and understanding of the worldview by a person.
