The purpose of the work was to study the patterns of development and formation of the structure of the skeletal, muscular, circulatory system under the influence of various physical activities in the dynamics, followed by the definition of correlations of the value of anthropometric and morphometric parameters in the training of athletes. Studying of the literature data, we can conclude that modern professional sports requires loads close to maximum, and sometimes even exceeding them, the establishment of these maximum permissible loads and the study of the patterns of their development is a very urgent task. The main problem in training athletes is adequate selection and sports affiliation. Solving the problems of selection involves the creation of a model of the athlete of this specialization, that is a certain set of characteristics that determine athletic performance. This requires anthropometric assessment, morphometric and biometric data to track physical and physiological parameters, information to assess performance and recovery in sports, modification of training regimes to prevent injuries, provide guidance on regulating the use of technologies used in professional sports, as well as to research and make recommendations for the proper collection, storage and exchange of health information. One of important problems of modern morphology is the study of changes that occur in the body under the influence of various factors. This problem has become especially important in connection with the development of sports. High sports performance, associated with a significant load on the athlete's body, encourages scientists, doctors, coaches to search for physiological reserves of the body and search for optimal training regimes. From this point of view, the study of changes that occur in individual organs, systems and in the body as a whole, under the influence of physical activity of varying intensity and nature is relevant and of great practical importance. Conclusion. Modern professional sports require loads that are close to the maximum, and sometimes are such or exceed them. It is the establishment of these maximum allowable loads and study the patterns of their development which is a very promising area. This will allow timely selection of athletes for a particular sport, to carry out preventive and curative measures to improve their structural and functional condition

The Creation

The main problem in training athletes is adequate selection and sports affiliation. Solving the problems of selection involves the creation of a model of the athlete of this sport, a certain set of characteristics that determine athletic performance. This requires anthropometric assessment, morphometric and biometric data to track physical and physiological parameters, information to assess performance and recovery in sports, modification of training regimes to prevent injuries, provide guidance on regulating the use of technologies that used in professional sports, as well as to research and make recommendations for the proper collection, storage and exchange of the health information. One of the important problems of modern morphology is the study of the transformations that occur in the body under the influence of various factors. This problem has acquired particular importance in connection with the development of sports. High sports performance associated with significant loads on the athlete's body encourage scientists, doctors, coaches to search for the physiological reserves of the body and search for optimal modes during training. From this point of view, the study of the transformations that take place in individual organs, systems and in the body as a whole, under the influence of physical loads of varying intensity and nature, is relevant and is of great practical importance. Studies have shown changes in the basic physiological and biochemical parameters in athletes, such as adaptation of the muscular, cardiovascular, and respiratory systems, the nature of muscle energy supply, and tissue metabolism processes. There are also scientific studies that reflect structural changes that appear in the body under the influence of physical exertion. The level of results in modern sports is so great that in order to achieve them, athletes need to have appropriate morphological and functional data, as well as excellent physical and mental abilities. Therefore, the main problem of training athletes is adequate selection and sports orientation. Solving the selection problems involves the creation of a model of an athlete of a given specialization, that is, a certain set of features that determine sports performance. The set of features and the order in which they are listed is different for different sports. In the conditions of sports selection, such morphological characteristics as total body dimensions (length), body proportions, body mass composition are taken into account.

During the Oxford Conference of the Econometric Society in September 1936, Ragnar Frisch proposed a problem in regression theory. A partial solution was found in 1938 by Miss H. V. Allen (1). A more complete solution was given by C. R. Rao (6) in 1947, and in the same year the present author (5) obtained a solution as a particular case of a more general result. These last two papers contained a flaw, and a correct solution was provided by Miss E. Fix (2). This last solution still leaves a part of the problem unanswered, and in the present paper a result of P. Lévy's (4), is used to complete the solution. At the same time further generalizations of the problem are considered and, in the cases of most practical importance, complete solutions are obtained. It is advisable, both from the point of view of rigour and simplicity of analysis, to use a general definition of the conditional expectation of a random variable. Accordingly, the paper begins with a summary of the relevant definitions. These notions were introduced by Kolmogoroff (3). It has been thought worth while giving the definitions here, in forms which are slightly different from Kolmogoroff's and seem more suitable for applications, in order to explain the notation and nomenclature used. The relevant consequences of these definitions are also stated in the form in which they are used.

The investigations which form the subject of the paper were begun with the object of verifying the statements made by several authors with regard to the origin and development of the so-called "heart" or pericardial vesicle of Echinoderms. A study of the literature soon led to the conclusion that our knowledge of the development of the organ was somewhat defective and that a thorough revision of its development and ultimate fate would be desirable. This work has occupied my attention for the last two years and the results obtained have been fairly satisfactory. Historical Resumé . The Echinodermata offer a number of most interesting problems to the comparative physiologist. They are in many senses the lowest animals, from the point of view of organisation, which possess a true cœlom or secondary body-cavity. It was always assumed by earlier naturalists that these animals must have a circulatory system and strenuous efforts were made to find a heart and blood-vessels. None of these efforts has been very successful because the so-called vessels were found to be mere rents in the loose connective tissue without proper walls of their own, and further, no connection could be traced between vessels in one part and those in another part. The fact that these vessels owe the honour of being denominated blood-vessels at all is because they contain a ground-substance, which unlike the ground-substance of the rest of the connective tissue, stains with aniline dyes such as eosin and methyl green. If there is to be true circulation some part of the system must be rhythmically contractile and so a heart had to be found. A pillar-like organ, lying alongiside the stone-canal in Echinoidea, Ophiuroidea and Asteroidea, was selected for the rôle. Unfortunately, in Holothuroidea, where the so called vessels are best developed, it is absent and this fact may be correlated with the elongated shape of the animal and the contractility of the body wall. Later, as repeated observation had failed to detect any sign of its beating, the non-committal term of "pseudo-heart" was adopted for it. It is now proposed to call it the “pericardial vesicle.”

<p>In the past years, the recording and collection of physical and physiological data from the body through wearable devices has become an increasingly common health-related practice in contemporary Western societies. The rapid development of digital self-tracking technologies has given rise to the production of different scientific discourses. The analysis of 200 published articles has led to the definition of a continuum between “technophile-promises” and “technocritical-risks” representations. However, these representations include different views of corporeality and sociality. Beyond this debate, we propose an alternative theoretical framework that links corporeality and sociality. It interrogates the psychological function that wearable devices may take (or not) for subjects to which these “tools” are addressed. We argue that such psychological function must be embraced by taking into consideration of activity done by the users of these technologies, which engages meaning: It is not the device, but the user him/herself who is confronted to the interpretation of biometric data linked to his/her own body functions on the basis of concrete lived experience. Moreover, we discuss that the activity of users can only be analysed in the sociocultural context to which the associated practices relate (health, sports, play, medicalisation). The conclusion highlights the need to further study the appropriation process of new personal experimentation instruments as to better understand the potential collaborations, risks or resistances that users may develop.</p>

All the hypotheses concerning the basic problems of schizophrenia have been disproved, challenged or simply never corroborated. We tried to find the reasons. The first step in any research seems to be the definition of its object, but there is no definition of schizophrenia. The influence of the organogenesis versus psychogenesis dispute and of the personal convictions of searchers is inevitable and very often unconscious; it is felt at all the levels of research. The interference of other personal factors is also controversial at the research team level and notably regarding the importance of the illness concerned. Bleuler spoke about “the group of schizophrenias”, but all the studies are carried out as if, behind the diversity of the clinical description there was one single and constant organic substratum. The limitations which this idea engenders are discussed. The emphasis is on the interest in studying acute beginning forms. Various etiopathogenetic hypotheses are taken into consideration when choosing methodology; it is the least limitating hypothesis which must be the deciding factor, namely that there are, in schizophrenia, some social-psychological and some organic factors, but the presence of only one factor of any kind is sufficient. The methodological conclusions are: the value of longitudinal studies compared with sectional studies, the importance of setting up homogeneous sub-groups for at least one additional datum over that of schizophrenia and the interest of repeating the tests recommended by different schools on the same subjects. For reasons of facility, most studies deal with chronic patients, and various criteria of selection are shown. Consequences of ‘institutionalization' in a mental hospital (secondary alienation) are also looked at from the point of view of the body: it seems to us that chronicity gradually changes a person into ‘another man’, biologically speaking. The peculiarities of diets in mental hospitals were at the beginning of many contradictions and mistakes in those studies; the part of other independent variables is taken into consideration; such as the level of physical activity, stress and chemical treatments. The problem of control groups for the sectional studies is shown. Throughout the text, examples are given of repercussions on some studies of the methodological problems raised.

In case of some nuclear power plants constructed at the soft soil sites, liquefaction should be analysed as beyond design basis hazard. The aim of the analysis is to define the postevent condition of the plant, definition of plant vulnerabilities, and identification of the necessary measures for accident management. In the paper, the methodology of the analysis of liquefaction effects for nuclear power plants is outlined. The procedure includes identification of the scope of the safety analysis and the acceptable limit cases for plant structures having different role from accident management point of view. Considerations are made for identification of dominating effects of liquefaction. The possibility of the decoupling of the analysis of liquefaction effects from the analysis of vibratory ground motion is discussed. It is shown in the paper that the practicable empirical methods for definition of liquefaction susceptibility provide rather controversial results. Selection of method for assessment of soil behaviour that affects the integrity of structures requires specific considerations. The case of nuclear power plant at Paks, Hungary, is used as an example for demonstration of practical importance of the presented results and considerations.

The essential difference, from the theoretical point of view, between an externally excitedlciody and a fish is that the latter can apply lateral vibratory movements at any part of its surface, whereas in the ‘artificial fish’ lateral vibrations are applied only at the point where the external force acts on the body. A good example which illustrates how the artificial fish swims is the ‘Pod’. The Pod is a medical device consisting of a small magnet attached to a plastic ‘tail’. If the Pod is placed in a patient's blood vessel, and an alternating magnetic field is applied, the magnet oscillates angularly and the plastic tail causes it to swim. The purpose of the device is to deliver medicaments at any desired location in the circulatory system.In this paper the theory of swimming of elastic slender bodies excited by an external force is presented. Special reference is made to the hydrodynamic forces acting on a swimming cylinder in viscous fluctuating flow. The results obtained are used in the analysis of the propulsion mechanism of the Pod.

Problem setting. The imperfection and obsolescence of national labor law raises a range of legal issues related to ensuring the proper implementation of the constitutional right to work and a number of social guarantees for workers’ rights. These problems include, in particular, the widespread practice of civil-law labor substitution, which is usually manifested through the conclusion of so-called civil-law contracts between the employer and the employee, rather than the proper design of relations in the manner prescribed by the Labor Code of Ukraine. The purpose of the research is to reveal the problematic issues of the distinction between labor and civil relations, both from the point of view of the existing doctrine of labor law, and through the prism of the existing rulemaking practice, aimed at improving national legislation on labor. Analysis of resent researches and publications. The issues of the distinction between labor and civil relations have become the subject of scientific analysis in the writings of such scientists as O.V. Zabrodina, L.O. Zolotukhina, M.I. Inshin, R.A. Maidanik, S.M. Prilipko, Ya.V. Svichkaryova, D.I. Sirokha, N.V. Fedorchenko, OM Yaroshenko and others. At the same time, these issues require further research in order to develop comprehensive recommendations aimed at improving labor law. Article’s main body. Among the variety of means of departure from classical labor relations, the two most common types of registration of relations between the employer and the employee in the civil plane can be distinguished: 1) conclusion of a civil contract (provision of services, contract, employment agreement) with an individual; 2) concluding a civil (economic) contract with an individual entrepreneur. The main reasons for the emergence of the practice of changing labor relations in civil law should be recognized as follows: obsolescence of Labor Code of Ukraine, the concept of which does not fully correspond to the current realities of the labor market; the need to optimize the tax burden on employers; lack of definition of labor relations in the legislation. Existing attempts to combat these negative phenomena, in particular the bill proposed by the Ministry of Social Policy of Ukraine in 2019, raise many objections because they are unable to systematically resolve the problem of the “shadow labor market”. Conclusions. The problem of the distinction between labor and civil relations is of great theoretical and practical importance and needs to be addressed promptly at the legislative level, in particular through the consolidation in the legislation of a clear list of features of labor relations, as well as the definition of types of work, the relationships within which can be solved exclusively at the level. In this context, it is necessary to adopt a new Labor Code, the provisions of which will meet economic realities and current labor market conditions.

Abstract. The article discusses the emergence of a functional literacy construct and the rediscovery of illiteracy in industrialized countries during the second half of the 20th century. It offers a short explanation of how the construct evolved over time. In addition, it explores how functional (il)literacy is conceived differently by research discourses of cognitive and neural studies, on the one hand, and by prescriptive and normative international policy documents and adult education, on the other hand. Furthermore, it analyses how literacy skills surveys such as the Level One Study (leo.) or the PIAAC may help to bridge the gap between cognitive and more practical and educational approaches to literacy, the goal being to place the functional illiteracy (FI) construct within its existing scale levels. It also sheds more light on the way in which FI can be perceived in terms of different cognitive processes and underlying components of reading. By building on the previous work of other authors and previous definitions, the article brings together different views of FI and offers a perspective for a needed operational definition of the concept, which would be an appropriate reference point for future educational, political, and scientific utilization.

Academic Debate

Over the past thirty years, academic debate over pornography in the discourses of feminism and cultural studies has foundered on questions of the performative and of the word's definition. In the polylogue of Droit de regards, pornography is defined as la mise en vente that is taking place in the act of exegesis in progress. (Wills's idiomatic English translation includes an ‘it’ that is absent in the French original). The definition in Droit de regards alludes to the word's etymology (writing by or about prostitutes) but leaves the referent of the ‘sale’ suspended. Pornography as la mise en vente boldly restates the necessary iterability of the sign and anticipates two of Derrida's late arguments: that there is no ‘the’ body and that performatives may be powerless. Deriving a definition of pornography from a truncated etymology exemplifies the prosthesis of origin and challenges other critical discourses to explain how pornography can be understood as anything more than ‘putting (it) up for sale’.
