The article is dedicated to the theoretical study of the process of convergence and integration of the digital and predigital environments. The general and distinctive features of the following concepts: “information society”, “information environment”, “digital environment” in terms of influence on an individual and on a social group are presented. Based on psychological research in various areas, the authors present a classification of stages where the convergence of the digital and pre-digital environment takes place. The concept of “interference” and its application in psychology and the related disciplines is revealed; the authors’ understanding of interference to describe the area of merging and integration of the digital and pre-digital environments is showcased. The results of the research can be of significance in the study of digital environments in both theoretical and empirical research, explaining the digital transformation of the subject.

The process of transitioning to an ageing population has occurred later, but nevertheless more intensely, in Southern Europe than in other regions. Consequently, these countries have been forced to politically, socially and economically adapt to this significant challenge. Sociologists play an important role in identifying and understanding social trends and issues, as well as in contributing to the design of public policies across Europe. However, research has tended to explore issues of ageing populations in Northern Europe, in spite of the notable demographic shifts and contextual specificities of Southern Europe. In response, this study has a dual objective: first, to collect the theoretical and methodological contributions of authors from or focusing on Southern Europe, and second to explore the originality of studies that belong to Southern European sociological traditions. In order to systematise the study, the theoretical paradigm of Marshall’s classification of social science theories in the field of ageing is used. Specifically, the present study incorporates the topics of active ageing, adult education and ageing at work as the main foci of analysis. The results of this theoretical study show that the sociology of Southern Europe can contribute significantly both to the issue of ageing and to public policies for its management, in the process providing a more holistic and human-centred approach.

The article is dedicated to the theoretical study of the process of convergence, integration of two types of activity – playing and working in the information society. The author's classification of the stages of research of playing as a philosophical, psychological and social phenomenon is proposed. There are three stages in the development of research of playing starting from the research of Immanuel Kant and Johann Christoph Friedrich Schiller to modern-day authors. Based on the analysis of modern authors’ study, it is shown that functions of working are increasingly filled with playing methods, and vice versa playing partially acquires the characteristics of work behaviour. The transformation of the main functions of playing in the conditions of the information society is also shown; i.e., the information environment acts as a factor of change. The results of the study can be used in the study of digital environments, in theoretical and empirical studies, to explain the transformation of work behaviour of a subject, as well as in the practice of various pieces of training in the field of human resource management.

This study is based on the valuation of a few model molecules. The objective of this research is focussed on the nonlinear optical (NLO) improvement of four organometallic molecules and one organic molecule. These molecules have been subjected to several calculations by different functionals: CAM–B3LYP, LC–BLYP, LC–wPBE, wB97X, M11, M06–2X, M08–HX and M08–SO. These functionals gave three orders of classification of the [Formula: see text] parameters. The CAM–B3LYP functional recorded very good agreement between [Formula: see text] parameters and gaps ([Formula: see text]. Significant first hyperpolarizabilities ([Formula: see text] have been obtained around 880 * 10[Formula: see text][Formula: see text]esu. The mechanisms of intramolecular charge transfer (ICT) have shown energetic passages from donor groups to acceptors and vice versa. The substitution of metals influences the location of [Formula: see text] electrons at the level of the chromophores. Finally, the lengthening of the aromatic chains between the acceptor and donor groups shows significant NLO improvements. The first and second hyperpolarizabilities ([Formula: see text] and ([Formula: see text] for a chain of several benzene rings are of the order of 21,663.16 * 10[Formula: see text][Formula: see text]esu and 16,464.65 * 10[Formula: see text][Formula: see text]esu, respectively.

Research  of  design-design  features of the creative collection of clothing using the technology of patchwork. Methodology.  An  integrated  approach, historical  analysis  of  the  object  of  research, systematization  of  parochial  species,  method of combinatorial formation have been applied. Results.  The  design  of  the  clothing  collection was  analyzed  using  the  paintwork  technique. The  historical  development  of  the  technology of patchwork is considered. There has been an improvement  in  the  type  classification  of  the patchwork,  which  includes  the  types,  seams and  blocks  of  the  art.  The  technology  of execution  of  the  units  of  the  peach  «flying geese» and «cut» is described. On the basis of the theoretical study carried out, an up-to-date collection of women 's and men 's clothing has been  developed  with  the  use  of  modern techniques  of  peachyard,  as  technologies of  repeated  application  and  processing  of sewing wastes and textiles.  The  views,  seams  and blocks of the patchwork are systematized. The specifics  and  possible  variants  of  modern paintings in the technology of patchwork and their  application  in  the  design-design  of  the collection  of  clothing  models  have  been revealed. Practical  significance.  The  possibilities  of using  modern  varieties  of  patchwork  in  the creation of a collection of  clothing have been demonstrated.  Proposed  is  a  technological method  of  making  pachopper  blocks according  to  templates  using  cutting  with  a disk  knife  and  crease  using  a  water-soluble stabilizer.

The article examines the essence, types, meaning and composition of enterprise resources, conducts a theoretical study of the classification of resources and their significance for the enterprise. Such concepts as "enterprise resources" and the main indicators that characterize it are revealed. The study of the views of scientists has shown that the concept of "resources" is quite controversial. The study of literature has shown that there are many different definitions and types of resources, depending on the type of activity of the enterprise, sources of formation or directions of use. The main indicators that characterize the company's resources are described and reserves and directions for their effective use are identified.

The aim of this paper is to define the architecture of the information analysis towards a proposal of methodology on systematic information analysis. First, the author shows the dimensions that state the architecture of information management. Second, the work explores the concept of indicator, as the measurement of the relation between data, and presents the results of a theoretical study of the scales that determine the analytical procedure of information from a systematic perspective. Third, the hierarchical architecture of indicators is reviewed from the literature taking the classification of scientometrics indicators as reference standard to its projection on extended metrics of information. The paper suggests from the review that the analytical progress of sequential application of indicators, based in a hierarchical architecture: (1) is the main guarantee to ensure a methodological systematisation of analytical procedure; (2) may be defined as the systematic order of intellection: (3) and allows a rigorous, integral and exhaustive information management in organisations.
