Green Synthesis of 2-thioxothiazolidin-4-one Derivatives in Deep Eutectic Solvents via Knoevenagel Condensation

Recently, more and more researchers are resorting to green methods and techniques to avoid environmental pollution. Accordingly, many researchers have been working on the development of new green synthetic procedures trying to avoid the use of toxic organic solvents. A sustainable concept of green and environmentally friendly solvents in chemical synthesis nowadays encompasses a relatively new generation of solvents called deep eutectic solvents (DESs). DESs often have a dual role in the synthesis, acting as both, solvents and catalysts. In this study, DESs are used in the Knoevenagel synthesis of rhodanine derivatives, with no addition of conventional catalysts. A model reaction of rhodanine and salicylaldehyde was performed in 20 different DESs at 80 °C, in order to find the best solvent, which was further used for the synthesis of the series of desired compounds. A series of rhodanines was synthesized in choline chloride: acetamide (ChCl:acetamide) DES with good to excellent yields (51.4 – 99.7 %).

METHODOLOGICAL INNOVATIONS IN EDUCATION

The article considers the introduction of innovative teaching methods and techniques as one of the most important areas of improving the training of students in modern society. The main thing in training is the need for self-education throughout life, the ability to understand people and cooperate in a team

METHODOLOGICAL FEATURES OF FORMATION OF THE CULTURE OF CRITICAL THINKING OF PRIMARY SCHOOLCHILDREN

The article deals with the methods and techniques for the development of critical thinking of primary schoolchildren, which are fundamentally different from the reproductive style of learning. The development of critical thinking of students can largely meet the requirements of modernity, namely: the content of education is considered not as a material for learning, but as a material for research; the student in this system is one of the main subjects of cooperation; the teacher, acting as an assistant, encourages students to maximum cognitive activity, maintains a creative psychological climate through co-creativity with students. It is noted that for the quality organization of the educational process and achievement of the set goals it is important to correctly apply the tools and methods of development of critical thinking. The article suggests a detailed description of the basic methods and techniques for the development of critical thinking and features of their application at primary school lessons. It is noted that the technologically correct application of methods and techniques for the development of critical thinking will promote active learning of students and form a culture of critical thinking.

Informal relations as a tool for socialization and adaptation of state and municipal employees

The article proposes an algorithm for assessing the environment of informal relations between employees of state and municipal institutions. The purpose of the study is to improve management processes by assessing informal relations as a tool for socialization and adaptation of employees of state and municipal institutions. Based on a literature review, objectives for managing informal relationships were set. Further, the characteristics of the environment of informal relations are revealed, for the assessment of which the methods and techniques of domestic and foreign authors can be applied. The paper offers recommendations on the application of methods and techniques for studying the environment of informal relations between staff of state and municipal institutions. Applied methods: analysis of sources, comparison, legal method. The novelty of the work lies in the substantiation of the application of methods and techniques for assessing the psychological climate in the team, the level of job satisfaction, conflict, informal leadership to study the environment of informal relations. The practical significance of achieving the desired level of the environment lies in the ability to increase the level of retention of employees, to provide flexibility in making managerial decisions and their implementation.

The Technological Advance and Application of Coprolite Analysis

Coprolites (mummified or fossilized feces), belonging to the group of ichnofossils, are fossilized remains of feces produced by animals. Various types of data from coprolites provide detailed evidence of the producer’s condition, like diet, intestinal microbiome, virus infection and parasites diseases. In addition, the palaeoenvironment information relevant to producers’ ecological niche can be drawn from taphonomy details the coprolites mirrored. At present, the phylogenetic clues of the producer’s population can be determined by advanced molecular biotechnologies. With the integration of multiple methods and techniques, coprolite has been widely accepted as an ideal material to study the diet, evolution, and palaeoenvironment of producers. In this paper, we reviewed the history of coprolite research, enumerated and interpreted the data recovered from coprolites, and explained their research value to palaeocoprology and evolutionary biology. Finally, we summarized the current directions of coprolite research and looked into its future prospects.

Weaving Security into DevOps Practices in Highly Regulated Environments

In this article, the authors discuss enhancing a DevOps implementation in a highly regulated environment (HRE) with security principles. DevOps has become a standard option for entities seeking to streamline and increase participation by all stakeholders in their Software Development Lifecycle (SDLC). For a large portion of industry, academia, and government, applying DevOps is a straight forward process. There is, however, a subset of entities in these three sectors where applying DevOps can be very challenging. These are entities mandated by security policies to conduct all, or a portion, of their SDLC activities in an HRE. Often, the reason for an HRE is protection of intellectual property and proprietary tools, methods, and techniques. Even if an entity is functioning in a highly regulated environment, its SDLC can still benefit from implementing DevOps as long as the implementation conforms to all imposed policies. A benefit of an HRE is the existence of security policies that belong in a secure DevOps implementation. Layering an existing DevOps implementation with security will benefit the HRE as a whole. This work is based on the authors extensive experience in assessing and implementing DevOps across a diverse set of HREs. First, they extensively discuss the process of performing a DevOps assessment and implementation in an HRE. They follow this with a discussion of the needed security principles a DevOps enhanced SDLC should include. For each security principle, the authors discuss their importance to the SDLC and their appropriate placement within a DevOps implementation. They refer to a security enhanced DevOps implementation in an HRE as HRE-DevSecOps.

Gamification in Classroom Management

This chapter is going to focus on the topic of gamification in classroom management. In this context, firstly, the definition, characteristics, theories of class management, and the strategies used in classroom management are going to be defined, and then gamification as the next generation strategy is going to be discussed. Although there are many studies on classroom management strategies that have been designed to make the education environment more effective in the literature, the use of these strategies in classroom applications may vary according to the practitioner and the classroom climate. However, it is seen that gamification has become increasingly important with the change in the perspectives and expectations of people and the advancement of the methods and techniques used in education.

Improving Project Management Decisions With Big Data Analytics

A relationship between project management and knowledge management was observed with a detailed level of analysis in this chapter, as analytics tools and methods were presented to define new perspectives for these dynamics. After a theoretical review that advanced the level reached by a previous paper on the same topic a new theoretical background was completely worked, resulting in a base where a deeper way of analysis allowed, at the end, to study practical cases of rich association for PM and KM in practical, ready to apply situations. As a trend for next competitive cycles, tools, methods, and techniques that focus knowledge production for decision making are to be increasingly defined and applied, on one hand enabling organizations to propose new competitive structures and positioning, and on the other hand, presenting a more aggressive, faster, and demanding competitive environment.
