The article deals with the method of constructing mathematical and software for modeling transients in large electronic circuits based on the decomposition of the original circuit into a number of subcircuits, followed by the calculation of the circuit in parts by diacoptics methods. The practical implementation of the proposed method allows you to significantly increase the performance of the software, reduce the cost of the required RAM and increase the speed of solving the problem of calculating transients, which is especially important in the development of distributed automation systems for circuit design due to the reduced time of dialog interaction between the system and the Internet.
A Service for Parallel Processing of Protected Information Queries in a Multi-Server Environment
Authors:   V. A. Trapeznikov Institute of Control Sciences of Russian Academy of Sciences, Moscow, 117997, Russian Federation, Asratian R. E.
Published: November 2021

The principles of organizing an Internet service designed to implement parallel processing of protected queries in distributed information systems that are oriented to work in complex network environments with many processing servers are considered. Distinctive feature of the service consists in a possibility to combine sequential ("pipelined") and parallel query processing in a multi-server environment. The service architecture is based on the concept of a "Protected message" corresponding to a container for electronic documents (information query or response) that can be provided with one or more electronic digital signatures. In contrast, for example, to the Web services technology, the described service is based not on the model of calling methods of remote objects, but on the message exchange model. In this case, this means that all service processing functions (methods) have the same strict specification: they receive an array of objects of the "Protected message" program class as a parameter and return an array of objects of the same class. In sequential processing, both arrays usually contain one "Protected message" object each. However, when using parallel processing, arrays can contain multiple elements that correspond to the results of processing by multiple software threads. These processing functions are grouped into one or more dynamic libraries, which are connected to the PMS server when it starts working (each library can be considered as a remote analogue of a Web service), and become available to clients.

The development relates to information technology and can be used to process medical images. This task is achieved by the fact that DICOM files containing the results of computed tomography of the human head are subject to correction. They change the color of the pixels at the transition points from black to gray or vice versa, and also replace the black pixel with white. As a result, the percentage of loss of information about small bones is reduced from 22-31 % to 3-5 %, and, therefore, the accuracy of the three-dimensional model of the facial skull of the human head is increased. All this contributes to a significant improvement in the quality of facial surgery.

Published: November 2021

This paper is about maritime safety. The system of vessel traffic schemas is one of the key elements of sea traffic control at the arias with heavy traffic. Such system based on a set of rules and guidelines defined by traffic schemas for certain water areas. From the classic approach, vessels that are not following the guidelines do not necessarily create alarming situations at the moment, however, could lead to complex danger navigation situations with the time passed. The problem of ship route planning through the area with highly intensive traffic is considered in this paper. The importance of the problem becomes more significant these days when taking in account development of self-navigating autonomous vessels. It is expected to respect area navigation limitations while planning vessel path through the areas with identified traffic schema. One of the ways to identify navigation limitations could be trajectory pattern recognition at certain sea areas based on retrospective traffic analysis. Model representation for such task could be based on vessel moving parameters clustering. The presented model is based on solving the shortest path problem on weighted graph. There are several ways to create such weighted graphs are suggested in the paper: regular grid of vertices and edges, layer grid of vertices and edges, random grid of vertices and edges, vertices and edges identified based on retrospective data. All edges are defined as a weighted function of "desirability" of one or another vessel course for each location of sea area with consideration of identified trajectory patterns. For that the area is divided into sub areas where courses and velocity clustering is evaluated. Possible ways of clustering are discussed in the paper and the choice made in favor of subtractive clustering that does not require predefining of cluster count. Automatic Identification Systems (AIS) could be used as data source for the traffic at certain sea areas. The possibility of using AIS data available on specialized public Internet resources is shown in the paper. Although such data typically has low density, they still could well represent vessel traffic features at the certain sea area. In this paper are presenting samples of route panning for Tsugaru Straight ang Tokyo Bay.

Segmentation as an effective method of isolating a brain tumor on MRI
Authors: Yurchuk Iryna , Kolesnyk Olena
Published: November 2021

Digital image processing, which ensues in many sides of life, is one of the areas that requires rapid development and improvement of existing algorithms, both for accuracy and completeness, and for reasons of speed and cost-effectiveness of both technical and software solutions. Medical application itself is the area where both precision in processing is important, as insufficient information affects the treatment protocol, and the cost for availability and widespread use. In this research, an algorithm for segmentation of digital MRI images of the brain is proposed in order to isolate the segment that contains the tumor. This algorithm is based on the sequential execution of the following steps: threshold Otsu’s method of binarization of the image, selection of brain and tumor tissues by morphological operations, segmentation by marked watershed, removal of the skull line and selection of the segment containing the tumor by an erosion. The verification did not reveal false-positive segmentation results, and the percentage of images correctly segmented to detect the tumor was 96.2%. It should be noted the high speed of the segmentation process obtained by the authors.

Big data is one of modern tools that have impacted the world industry a lot of. It also plays an important role in determining the ways in which businesses and organizations formulate their strategies and policies. However, very limited academic researches has been conducted into forecasting based on big data due to the difficulties in capturing, collecting, handling, and modeling of unstructured data, which is normally characterized by it’s confidential. We define big data in the context of ecosystem for future forecasting in business decision-making. It can be difficult for a single organization to possess all of the necessary capabilities to derive strategic business value from their findings. That’s why different organizations will build, and operate their own analytics ecosystems or tap into existing ones. An analytics ecosystem comprising a symbiosis of data, applications, platforms, talent, partnerships, and third-party service providers lets organizations be more agile and adapt to changing demands. Organizations participating in analytics ecosystems can examine, learn from, and influence not only their own business processes, but those of their partners. Architectures of popular platforms for forecasting based on big data are presented in this issue.

Published: November 2021

This article considers approaches to the formation of models of proactive management of projects for the creation and development of distributed information systems. Features of distributed IT projects as a complex adaptive system that develops under numerous interrelated constraints are considered. It is concluded that the projects themselves are distributed. The main trends in the development of such systems were analyzed, the main patterns and problems were identified. The focus is on the consideration of the basic components of such systems and formalized models are proposed to describe their interaction. Attention is paid to the formation and implementation of projects to create complex systems based on distributed information systems, where the main features are the action of a significant number of complex influences from the turbulent external environment. The issues of project reactions to the effects of these changes were investigated. To address the management of such complex projects, a proactive approach is proposed. The consequences of changes in the processes of creating such systems are studied. A mathematical model of minimizing the effects of changes on project elements in the management of complex projects is proposed and an approach to the configuration management of such projects is proposed, which in general allows to build a scheme of effective project management.
Hebrew names and name authority in library catalogs
Authors:   ,   Jewish University of America, Stuhlman Daniel
Published: November 2021

Because of the differences in alphabets, entering Hebrew names and words in English works has always been a challenge. The Hebrew Bible (Tanakh) is the source for many names both in American, Jewish and European society. This work examines given names, starting with theophoric names in the Bible, then continues with other names from the Bible and contemporary sources. The list of theophoric names is comprehensive. The other names are chosen from library catalogs and the personal records of the author. Hebrew names present challenges because of the variety of pronunciations. The same name is transliterated differently for a writer in Yiddish and Hebrew, but Yiddish names are not covered in this document. Family names are included only as they relate to the study of given names. One chapter deals with why Jacob and Joseph start with "J." Transliteration tables from many sources are included for comparison purposes. Because parents may give any name they desire, there can be no absolute rules for using Hebrew names in English (or Latin character) library catalogs. When the cataloger can not find the Latin letter version of a name that the author prefers, the cataloger uses the rules for systematic Romanization. Through the use of rules and the understanding of the history of orthography, a library research can find the materials needed.

Experimental researches of the characteristics of antennas in the presence of electromagnetic screens
Authors: Shlyahov A.V.
Published: November 2021

When placing various antenna systems in a confined space, one has to deal with a complex electromagnetic environment and insufficient isolation between the antennas. And, although the methods of ensuring electromagnetic compatibility of such groups of radio electronic means are well known, taking into account the peculiarities of the objects under consideration, they have very limited application. The use of innovative technologies developing in recent years, including the use of screens made of metamaterials, makes it possible to significantly expand the "limits of applicability" of these methods. As the studies have shown, the screen made of metamaterial has special characteristics in comparison with traditional screens, namely: at the operating frequency of the antenna, the screen is practically permeable to electromagnetic radiation, and at the interference frequency it becomes low-transparent and works as a reflector. The results can be used to improve isolation between closely spaced antennas, such as at the tops of towers or masts.
Antenna radome based on metal-dielectric gratings as angular filter at microwaves
Authors: Kasyanov A.O.
Published: November 2021

This article is devoted to the analysis of numerical study results of printed angular filters scattering characteristics. It is shown these angular filters may be used as antenna radomes. Numerical results are obtained by full-wave simulation of frequency-selective surfaces with dielectric covers. The numerical research results of the scattering characteristics of a printed angular filter as antenna radome based on metal-dielectric gratings are presented. A comprehensive numerical study of microwave angular filters based on multi-element multilayer printed reflect arrays has been carried out. Constructive solutions for metal-dielectric structures in integral design, realizing the functions of angular filters, are found. These solutions are based on performed numerical studies. The problems of constructive implementation of multilayer planar spatially selective as angular filters are considered. These angular filters are integrated into the radiators and feeders of modern multi-element printed phased arrays. The problems connected with creation of such arrays are also considered. The numerical simulation results for angular filters based on metal gratings with dielectric covers are obtained. These results can be used to select the most rational options for the topology of metal-dielectric gratings. Such solutions may be useful for design of multifunctional radomes in microwave antenna systems. Based on the obtained numerical data, the possibilities of using flat gratings as angular filters in the composition of antenna radomes are considered. The spatial frequency-selective structures proposed in this work are performed as multi-planar printed gratings. These gratings are designed to ensure electromagnetic compatibility of closely spaced radio electronic sets. These radio electronic sets operate in close frequency ranges. They contain antenna arrays. These arrays are placed under the antenna radomes. At the same time, the installation of angular filters in the antenna radomes makes it possible to eliminate the appearance of unwanted grating lobes in the radiation patterns of sparse antenna arrays of promising radioengineering sets at microwaves.
Planar slotted ridged waveguide antenna arrays with dielectric layer
Authors: Pelevin A.O. , Zargano G.F. , Lerer A.M.
Published: November 2021

The paper simulates the options available to move operating range of slotted waveguide antennas downward in frequency without changing the waveguide cross-section, and suggests the ways for designing linear waveguide-slotted elements based on rectangular and ridge waveguides with air and partial dielectric filling. The critical frequency of the fundamental mode of a 16x8 mm rectangular waveguide moves by ridging from 9.5 to 6.5 GHz. Partial dielectric filling of the cavity of the ridge waveguide makes it possible to additionally shift the operating range downward in frequency by 6-10% without making changes to antenna design. The antenna characteristics of linear arrays based on a dielectric-filled ridge slotted waveguide have been compared in terms of gain and voltage standing wave ratio to similar designs of arrays on rectangular and air-filled analogues. Based on the obtained structures of linear elements, simulation models of planar arrays have been constructed so that they have the similar area of total surface. Simulated frequency dependence of the realized gain for planar arrays has demonstrated a shift of the operating range downward in frequency. The analysis of the directivity characteristics of planar arrays for various phase shifts between the linear elements has been carried out. The simulation results have shown that the use of a dielectric-filled ridge waveguide gives an advantage in phase scan angle of the main beam of the radiation pattern. With the same phase shift, in planar arrays of dielectric-filled ridge waveguides, the main beam scans for a larger angle while keeping side lobes at low level. Thus, the use of a ridge slotted waveguide with a dielectric layer inside makes it possible to expand the phase scan angle.

Possible approaches to reducing the risks of nuclear escalation at the regional level
Authors: Zolotarev Pavel
Published: November 2021

The article deals with issues related to the task of reducing the risks of escalation of a local military conflict to the level of a nuclear one. To find ways to solve this problem, three aspects are considered – doctrinal, concerning official views on the use of nuclear weapons; features of the means of delivery of tactical nuclear weapons; features of the storage of tactical nuclear ammunition; the influence of high-precision weapons. The main doctrinal provisions are considered for Russia, the United States and China. The conclusion is substantiated that it is expedient to consolidate in the doctrinal documents of nuclear states or in other forms of mutual obligations the provision that each state will develop new non-nuclear systems of armed struggle with a simultaneous reduction in the role of nuclear weapons in ensuring security. To reduce the risk of escalation of the conflict to a nuclear one, it is proposed to work out the issue of refusing to create and deploy delivery vehicles that allow their use for both conventional and nuclear strikes. Relevant proposals have been made regarding the deployment of short-range nuclear weapons carriers and storage sites for nuclear charges, aimed at minimizing the risk of the use of nuclear weapons. An assessment of the capabilities of high-precision weapons to disrupt strategic stability when trying to use them for decapitating or disarming strikes is carried out. The conclusion is made about the unreality of such scenarios. A comparative analysis of the risks of escalation of military conflicts to the nuclear level was carried out for the European and Asia-Pacific regions. Taking into account the achieved level of survivability of the Chinese nuclear potential and the prospects for its development, it is assumed that there is a higher risk of an escalation of a military conflict for the European theater.
Priority Areas for Mangrove Conservation to Support Disaster Mitigation Efforts in Pacitan Bay

Published: November 2021

Mangrove ecosystems at the estuary of Teleng River, Pacitan Bay, call for preservation, protection, and development as a natural vegetative defense against tsunami impacts. Limited availability of potential land for mangrove growth poses a challenge to sustainable mangrove management. To anticipate land acquisition for another use, it is necessary to study land suitability for mangrove and mangrove conservation priorities in the Pacitan Bay. The land suitability parameters consisted of landform, slope, soil texture, and tidal fluctuation, while the mangrove conservation priority was determined based on several aspects: mangrove land cover reduction, mangrove damage level, beach ridge and riparian zone, and land suitability. The results indicate that lands with high potential for mangroves are distributed along Teleng and Grindulu Rivers but not precisely at the estuary. Based on the suitability results, highly potential and potential lands are proposed for mangrove planting, while existing mangroves are for protection and preservation zones, especially on the sides where relatively young mangroves grow for their roots are not strong enough to withstand river currents.

BACKGROUND Cardiovascular diseases are one of the leading causes of morbidity and mortality worldwide. High Ca levels and low Mg levels are associated with increased cardiovascular risk in the general population.1 The balance between Ca and Mg seems to play an important role in homeostasis since Mg is considered as physiologic antagonist of Ca.2 Hence Ca/Mg ratio was considered to study its association with acute coronary syndrome (ACS). METHODS This is a case control study conducted in Karnataka Institute of Medical Sciences, Hubli over a period of 2 years, February 2019 to December 2020. 200 cases and 150 controls were included in the study. The biochemical measurements including complete blood count (CBC), cardiac biomarkers, liver function tests, renal function tests (RFT), serum electrolytes and lipid profile were measured using standard laboratory methods. Student ‘t’ test was used to compare the data. Optimum cut-offs for diagnosis of acute myocardial infarction was calculated using receiver operating characteristics (ROC) analysis. The association among markers was established by calculating Pearson’s correlation. RESULTS Serum Ca/Mg ratio was significantly higher (p value < 0.001) in ACS when compared to control groups. It was also found that Ca/Mg ratio was significantly lower (p value < 0.001) in non-ST elevation myocardial infarction (NSTEMI) when compared to STEMI group. Serum Mg was significantly lower (p value < 0.001) in ACS group when compared to control group. Significant correlation (p value < 0.05) was found between serum Ca/Mg ratio and cardiac markers (CKMB, Troponin-I). ROC analysis of Ca/Mg (4.19) ratios showed optimum cut-offs in diagnosis of AMI. CONCLUSIONS Serum Ca/Mg could be useful adjuvant marker in diagnosis of AMI. The ratio is higher in ST-segment elevation myocardial infarction when compared to non-STsegment myocardial infarction, which could be due to greater decrease in Mg levels when compared Ca in ACS.

Published: November 2021

BACKGROUND An ideal surgery to remove hypertrophied adenoid mass should be safe, with less bleeding and operation time along with post-operative improvement in the eustachian tubal ventilation and normal respiration. It should also have low morbidity and mortality. Among the various methods described for its removal, the two commonly used methods are conventional cold curettage method and coblation technique. The purpose of this study was to collate the safety and efficacy of endoscopic coblation adenoidectomy with the conventional curettage adenoidectomy. METHODS A prospective comparative study with fifty patients was studied who underwent adenoidectomy. Twenty five patients underwent endoscopy assisted coblation adenoidectomy and twenty five patients underwent regular adenoidectomy by curettage. RESULTS Patients who underwent coblation adenoidectomy showed better results during follow up in terms of completeness of removal. 80 % of children undergoing regular adenoidectomy by curettage method showed remnant adenoid tissue in the nasopharynx at the end of the procedure. But it was 6 % among the children undergoing endoscopic assisted coblation adenoidectomy. The mean duration of operation was higher for endoscopic assisted coblation adenoidectomy which was significant statistically. The mean blood loss was 30.36 ml in regular curettage adenoidectomy; 10.6 ml with endoscopic coblation adenoidectomy. The grading of pain was significantly lower in endoscopic assisted coblation adenoidectomy. There was no significant difference between two groups in terms of eustachian tube function after surgery. CONCLUSIONS Coblation adenoidectomy has significant advantages over conventional adenoidectomy in terms of completeness of removal, reduced blood loss, and lower post-operative pain grade.

Published: November 2021

BACKGROUND The clinical profile and outcome of snake bite varies from place to place and depends on a number of factors including the type of snake bite, place of snake bite, time of bite, season, and duration of presentation after bite. The clinical profile, factors affecting the outcome and the outcome have not been previously well studied. METHODS This is a cross-sectional observational study conducted for a duration of six months from January 2021 to June 2021. Subjects meeting inclusion criteria were enrolled in the study group after obtaining written consent. Patients were evaluated based on the standard pro-forma with detailed history and clinical examination. All relevant investigations to assess systemic envenomation, treatment and outcome were documented in all the patients. RESULTS In the study, 204 (68 %) were male patients and 96 (32 %) were female patients. 108 (36 %) were admitted with venomous snake bite and 192 (64 %) were with non-poisonous snake bite. 52 patients had snake bite on the upper extremities, 234 had snake bite on the lower extremities, 8 patients had snake bite on the trunk whereas 6 patients had bite on other areas of the body. 202 patients had swelling at the bite site, 222 had pain at the site of bite, 86 patients had oozing of blood and 6 patients had vague somatic symptoms. 132 patients had local oedema, 148 had local tenderness, 66 patients had skin necrosis and 16 patients developed blisters at the site of bite. 124 patients had systemic manifestations of which 24 patients had vomiting, 12 patients developed abdominal pain, 10 patients developed anuria/oliguria, 14 patients developed hypotension, 12 patients developed bleeding manifestations, 10 patients developed neurological symptoms and 2 snakebite patients had syncope. Complications and mortality in poisonous snake bite due to renal failure was observed in 38 patients with a mortality of 1 patient, 10 patients developed intravascular haemolysis, 8 patients developed unexplained hypotension, 18 patients developed secondary infection, 4 patients developed intra-cerebral bleeding and 15 patients developed neurotoxity with a mortality of 2 patients. CONCLUSIONS Snake bite is a common problem encountered in tertiary care centres and the most common encountered type of snakebite was haemotoxic bite. Pain at the bite site was the commonest symptom and tenderness at bite site was the commonest sign in patients with snake bite. Mortality in venomous bite was 3.7%. Prolonged bite to needle time, development of renal failure, leukocytosis, neurotoxicity and severe degree of coagulopathy were factors associated with adverse outcome.

Published: November 2021

BACKGROUND Establishing the usefulness of adaptive radiotherapy in our setting with limited data might help to ensure better conformity and reduce treatment related morbidity. Hence we conducted this study to elicit the benefit of adaptive radiotherapy with helical tomotherapy. METHODS This is a prospective study conducted among 25 head and neck cancer patients undergoing radiotherapy with helical tomotherapy. All patients underwent initial radiation therapy treatment planning simulation positron emission tomography computed tomography (PET CT/ CT scan) [CT-1], followed by repeat PET CT/ CT scan at 4th - 5th week of radiotherapy [CT-2]. Planning for full intended dose [66 Gy - 70 Gy] was done on both the scans, keeping the radiation therapy planning parameters same. Changes in the volume of the clinical target volumes (CTV), changes in the volume and dose to spinal cord, bilateral parotids, and mandible were compared. A p - value of < 0.05 was considered for statistical significance. RESULTS A significant reduction in the volumes of tumour - CTV-1 [CT-1 v/s CT-2: 166.82 cc v/s. 150.63 cc] and of lymph nodal region - CTV-2 [CT-1 v/s CT-2: 260.29 cc v/s 228.00 cc], contra lateral parotid gland [CT-1 v/s CT-2: 33.00 cc v/s 18.72 cc] were observed (P < 0.05). The mean doses received by contra lateral parotid gland [CT-1 v/s. CT-2: 23.14 Gy v/s 21.26 Gy] were significantly lesser in the CT2 scans (P < 0.05). The mean maximum doses were also significantly lesser to the mandible and spinal cord i.e., CT-1 v/s. CT-2: 68.528 Gy v/s 67.39 Gy and 39.45 Gy v/s. 37.33 Gy respectively (P < 0.05). A significant reduction in standardised uptake value (SUV), values of the primary tumour and involved lymph nodes was observed between CT-1 and CT-2. CONCLUSIONS During 4th to 5th week of radiation therapy, significant reductions in the CTVs and in dose to OARs were noted. Thus, we recommend at least one re-simulation scan and re-planning during radiation therapy, irrespective of the type of technique of radiation therapy.

Published: November 2021

BACKGROUND Rhino-orbito-cerebral mucormycosis (ROCM) is a devastating fungal infection with very high rates of mortality. Many patients post corona virus disease (COVID) infection are increasingly being diagnosed with mucormycosis (black fungus). Imaging being central to the early diagnosis of the infection, the study aims to characterize the major radiological patterns of involvement of mucormycosis. Computed tomography (CT) & magnetic resonance imaging (MRI) findings of 10 patients who were subsequently conformed to have mucormycosis were analyzed and 7 major patterns of involvement were detected. Imaging plays a vital role in the early diagnosis of ROCM. Knowledge about the common patterns of spread helps in picking the subtle signs of infection.

The problem of social intellect noospherization is being discussed. It is shown that the basis for formation of noospheric intellect and noospheric personality is the successful acmelogisation of institutional education subjects. The author’s classification of acme-personalities is suggested, with the criteria basis of noospheric orientation for both individual and social consciousness. It is shown that formation of noosperic orientation of social intellect (and its components – social consciousness and social knowledge) is encouraged by systematic and complex general social processes in institutional acmelogisation of its subjects (homeostasis, adaptation, socialization and social self-actualization); institution-educational processes (studying, self-studying, education and self-education, development and self-development, enlightenment and selfenlightenment); organizational-managerial processes (constructing, projecting, modeling, diagnostics, monitoring, stimulating, counseling, predicting). The project for noospherization of Russians’ social intellect is briefly presented.

It presents the analysis data of psychological conceptions (conception of stage brain building, psychoanalytical conception of culture, socio-analytical theory) that form the basis for modern methodology in researching tolerance development of a personality and give an opportunity to confirm that individual tolerance development repeats the stages of its general social and historical development. The author presents his scheme of ontogenetic stages of personality development and levels of tolerance development the basis for which is the principle of phylogenesis and ontogenesis unity formulated by E. Haeckel. The article views the main stages of personality tolerance formation: latent; empirical; collectivist or conformal; maturating or crisis, egocentric; mature.

The article presents the results of longitudinal study of person-adaptational potential of prisoners in a correctional institution. Personal-adaptational potential is viewed as the factor that determines formation of effective strategies in behavior of prisoners under conditions of serving a sentence. The research is made from proportionally selected sample of prisoners convicted for committing felonies who study at the Higher Professional University of the city of Novoulyanovsk (with the use of telecommunication technologies) and who do not study (n = 185; at the age of 30 years old; average term of punishment – 5 years and 3 months). The use of multi-factor personal questionnaire «Adaptivity» of A.G. Maklakov and S.V. Chermyanin, methods of observation, content-analysis of prisoners’ documents, comparative and correlation analyses makes it possible to identify the low representation of such parameters of adaptivity as «behavioral regulation», «communicative potential», «moral normalization» in the samples under investigation. The author defines inter-group differences by a range of features of adaptivity (communicative potential, moral normalization), that have the greatest expressiveness from prisoners put in the educational process. The author concludes that in the process of receiving Higher Professional Education effectiveness of adaptational processes becomes higher among prisoners. The applied aspect of the problem being investigated can be realized in consulting practice of psychological services in the system of execution of a punishment.

Modern approaches to studying the phenomenon of parenting are being analyzed. It is shown that fatherhood and motherhood as components of parenthood phenomenon are different ways of actualizing individual, gender and socio-cultural parental roles. The data was obtained of the sample of student-age people of Saratov State University named after N. G. Chernyshevsky (n = 60, largely females, age 16–22, 12% of them married). To study the ideas of parenthood the association experiment was applied (the testees were suggested writing ten words that came uppermost associating with the stimulus-concept “parenthood”); to specify the data of association experiment the conversation was used. The author comes to the conclusion that parenting practice is composed of many factors, the most important of them is parent’s appropriate idea of his/her role, and also the experience of parenting style that the parent used to have in the past; for the family to overcome the parenting style crisis it is necessary to form psychological readiness for parenting in the future generation parents long in advance having a baby. Data of empiric research proves the low level of psychological readiness for parenting with the student-age population. The applied aspect of work can be actualized in family-counseling practice of psychological services.

Published: November 2021

The article analyzes the phenomena of a «personal knowledge» in the concept of M. Polanyi, investigating classic problem of object-subject interrelation in the cognition from the point of view of the latter one. It shows that a subject in the cognitive activity is not to be determined by objective regularities, but rather by a personality, as the result of cognitive activity depends on its qualities and abilities. The author fixes the most important levels of subjective organization of cognition: humanity, society, scientific society, personality. He concludes that evolution of model vision of the role and functions in the development of science of these levels of subjective organization of cognition does not have limits, because it supposes the introduction of new subjective characteristics, recognition of the unknown and conceptually inexpressible earlier interconnections and regularities.
