С помощью метода артериальной пьезопульсометрии выполнены статистический и спектральный анализы вариабельных параметров ( VPP и TNN ) пульсовых волн АД крови у пациентов 18-85 лет. С высокой точностью оценены индивидуальные особенности автономной (вегетативной и нейроэндокринной) регуляции мышечных эффекторов (МЭ) сердечно-сосудистой системы (ССС) у пожилого мужчины (75 лет) и молодой женщины (20 лет). Эти данные, а также результаты сравнительного исследования пациентов разного возраста позволили выявить определенную закономерность направленного изменения симпатоадреналовой регуляции МЭ ССС в онтогенезе человека. Сделан вывод, что у людей в процессе жизни происходит перестройка физиологического механизма автономной регуляции МЭ ССС, направленная на замену краткосрочной симпатической регуляции у молодых людей на более эффективную и устойчивую регуляцию гуморальными катехоламинами у пожилых людей. Using the method of arterial piezopulsometry, statistical and spectral analyzes of variable parameters ( VPP and TNN ) of pulse waves of blood pressure in patients aged 18 to 85 years were performed. The individual characteristics of the autonomous (vegetative and neuroendocrine) regulation of the muscular effectors (ME) of the cardiovascular system (CVS) in an elderly man (75 years old) and a young woman (20 years old) were estimated with high accuracy. These data, as well as the results of a comparative study of patients of different ages, made it possible to identify a certain pattern of directed change in the sympathoadrenal regulation of ME CVS in human ontogenesis. It is concluded that in the course of their lives, people undergo a restructuring of the physiological mechanism of the autonomous regulation of their ME CVS, aimed at replacing short-term sympathetic regulation in young people with more effective and more stable regulation by humoral catecholamines in elderly.

The article analyzes the methods of calculating the intensity of aerobic health-improving loads and presents own solution the problem. The effective use of aerobic exercises is based on the formula calculation of the parameters of physical activity corresponding to the individual characteristics of the practitioners, among which one of the most important is intensity. However, the practical application of the proposed formulas indicates that they do not always adequately take into account the most important, in this case, age characteristics and the functional state of the cardiovascular system. The purpose of the research is to develop a method for determining the intensity of aerobic health-improving loads which makes it possible to calculate the target heart rate more adequately than the currently existing options. Among the existing formulas the most adequate for calculating heart rate in the process of health-improving aerobic exercise is Karvonen's formula which takes into account not only age but also heart rate at rest which reflect the functional state of the cardiovascular system. Its advantage lies in the more correct determination of the lower target pulse. The disadvantage of this formula is that it reduces, rather than increases, the upper target pulse due to the increased efficiency of the cardiovascular system. During the theoretical research it was established that it was impossible to develop a single formula that would allow to correctly determine the upper and lower target pulse. In this regard we came to the conclusion that to calculate the lower heart rate it is necessary to use the Karvonen formula and the upper tagert puls should be determined by the formula developed by us. It is based on the Haskell & Fox formula (HRmax = 220 - age). The proposed additions determine the upper heart rate as the result of subtracting the individual heart rate from the average age heart rate. A procedure for calculating specific puls based on knowledge of the upper and lower heart rate is proposed.

The urgency of the researched problem is connected with the growing role of mass media in modern conditions leads to change of values and transformation of identity of the person. The active growth of the role of the media, their influence on the formation and development of personality leads to the concept of “media socialization” and immutation in the media. The aim of the study is to outline the possibilities of the process of media socialization in the context of immutation in the media. The methods of our research are: analysis of pedagogical, psychological, literature, synthesis, comparison, generalization. The article analyzes the views of domestic and foreign scientists on the problem of immutation in the media and the transformation of the information space. In the context of the mass nature of the immutation of society, the concept of “media socialization” becomes relevant, which is the basis for reducing the negative impact of the media on the individual.The author identifies the lack of a thorough study of the concept of “media socialization” in modern scientific thought. Thus, media socialization is associated with the transformation of traditional means of socialization, and is to assimilate and reproduce the social experience of mankind with the help of new media.The article analyzes the essence of the concepts “media space”, “mass media” and “immutation”. The influence of mass media on the formation and development of the modern personality is described in detail.The study concluded that it is necessary to form a media culture of the individual, to establish safe and effective interaction of young people with the modern media system, the formation of media awareness, media literacy and media competence in accordance with age and individual characteristics for successful media socialization. The role of state bodies in solving the problem of media socialization of the individual was also determined. It is determined that the process of formation of media culture in youth should take place at the level of traditional institutions of socialization of the individual.The author sees the prospect of further research in a detailed analysis and study of the potential of educational institutions as an institution and a means of counteracting the mass nature of the immutation of society.Key words: immutation, media socialization, mass media, media space, information.

The paper analyzes the factors that affect the amount of effort required to create a mobile application and its cost. It is established that the main factors of influence are the design of the application, its functionality, the type of mobile platform, the availability and level of testing and support, as well as the individual characteristics of the developer. Based on the analysis of information sources, the main methods and approaches to forecasting the cost of software products are identified, which include the COCOMO model, Price-to-win method, expert evaluation, algorithmic methods and the method of analogies. It is proposed to consider the method of analogies as a tool that allows you to make predictions about the cost of resources required for the successful implementation of IT projects based on the experience of similar projects. It is proved that the advantages of this method are the simplicity of its implementation and the clarity of the results obtained, which follows from the practical orientation of this tool. Among the limitations of the method of analogy is the mandatory need for reliable data relating to similar projects, as well as the difficulty of taking into account unspecified indicators. Taking into account the mentioned limitations of the method of analogies and on the basis of the analysis of scientific sources the possible directions of its optimization are determined. Thus, among the ways to improve the effectiveness of this method are those aimed at optimizing the project selection process, the data for which are used as a basis for forecasting. Attempts to improve the method of analogies by including parameters that were previously ignored by this technique seem promising. This in turn can lead to an expansion of the scope of the method of analogies and increase the accuracy of forecasts. As prospects for further research, the need to continue research in the field of optimization of the method of analogies with the subsequent practical verification of theoretical positions on the data of real projects.

During the development of oil and gas fields and transportation of hydrocarbons, the ecology of regions is subject to various negative impacts. The most severe consequences for the environment are caused by accidental spills of oil or petroleum products, which occur due to through damage to pipelines. Polluted territories are subject to mandatory reclamation in accordance with government regulations and industry regulations. However, despite the measures taken by the administrations of the northern regions to increase the rate of reclamation of damaged territories in recent years, there has been a trend of growth of areas contaminated with hydrocarbons.Various remediation technologies that have been tested in warm and temperate climates are not very effective in regions with permafrost. Pollution of the daytime surface with oil or petroleum products leads to an increase in the absorption of the sun's radiant energy, the growth of the seasonal thaw layer and the development of destructive processes for the territory. To achieve a positive effect as a result of rehabilitation measures, it is necessary to take into account the individual characteristics of the territory and the extent of its pollution.

Research on visual feedback has not produced consistent results to show how visual feedback or the lack, thereof, influences individual handwriting characteristics. A two-pronged approach was designed to investigate the degree of this influence. For this purpose, samples of signatures as well as cursive and block text, written with and without visual feedback, were collected from 40 volunteers and imported into a PC via a pen tablet, using an electronic inking pen. The data was analyzed in a handwriting movement analysis software module specially designed for this research that was added to the software MovAlyzeR by Neuroscript LLC. Two forensic document examiners (FDEs) independently analyzed samples from the two groups (samples executed with normal visual feedback versus the group of samples executed without visual feedback). They found no fundamental differences between these two groups. Their analyses also demonstrated that a large number of similarities existed in the general design of the allographs (alternative forms of a letter or other grapheme) and in the pictorial aspects, regardless of the complexity of the samples. In the cursive and block handwriting, four main qualitative characteristics were linked to the absence of visual feedback: change of overall size, non-uniformity of left margins, change of baseline alignment, and inclusion of extra trajectories. The statistical analysis verified the above findings. The comparative analysis also suggests that gender, educational level (above high school) and handedness create an insignificant influence on the individual characteristics of writing produced with and without visual feedback. The only notable exception is the relationship between signature duration and educational level. The volunteers with a medium education level showed a significant increase in duration while signing their names without visual feedback in comparison to those with higher education levels. The combination of the above findings suggests that handwriting is not fundamentally influenced by visual feedback.  Purchase Article - $10

Sustainable mobility is becoming a key factor in improving the quality of life of the residents and increasing physical activity (PA) levels. The current situation of sustainable mobility and its analysis is a first step in understanding the factors that would encourage residents to discover and choose alternative modes of travel. The present study examined the factors that encourage the choice of active modes of travel among urban adult population. Walking and cycling were analyzed as the most sustainable forms of urban mobility from the perspective of car and public transport (PT) users. Total of 902 subjects aged 18 years or older were analyzed in the study to assess commuting habits in Kaunas city, Lithuania. The majority (61.1%) of the respondents used a passenger vehicle, 28.2% used PT, and only 13.5% used active modes of travel. The results showed that safer pedestrian crossings, and comfortable paths were the most significant factors that encourage walking. A wider cycling network, and bicycle safety were the most important incentives for the promotion of cycling. Our findings show that the main factors encouraging walking and cycling among car and PT users are similar, however, the individual characteristics that determine the choice of these factors vary significantly.

In vitro models are often used for studying macrophage functions, including the process of phagocytosis. The application of primary macrophages has limitations associated with the individual characteristics of animals, which can lead to insufficient standardization and higher variability of the obtained results. Immortalized cell lines do not have these disadvantages, but their responses to various signals can differ from those of the living organism. In the present study, a comparative proteomic analysis of immortalized PMJ2-R cell line and primary peritoneal macrophages isolated from C57BL/6 mice was performed. A total of 4005 proteins were identified, of which 797 were quantified. Obtained results indicate significant differences in the abundances of many proteins, including essential proteins associated with the process of phagocytosis, such as Elmo1, Gsn, Hspa8, Itgb1, Ncf2, Rac2, Rack1, Sirpa, Sod1, C3, and Msr1. These findings indicate that outcomes of studies utilizing PMJ2-R cells as a model of peritoneal macrophages should be carefully validated. All MS data are deposited in ProteomeXchange with the identifier PXD022133.
