Factors of social orientation on physical activity and methods of their application in the process of formation of motives of physical activity of the person
Authors: Pankratov M. 
Published: May 2021

Social and valuable orientation on health activities is formed and regulated with the help of influence on a person (social group) by certain factors. The overall understanding the word as factor is the main reason; moving force of some process; some relations and relationships; this is that is conditioned objective necessary or subjective desired result.
Factors of health activities are connected at overall system which has own construction and functions. Their main elements are two groups of factors: social and natural ones. The action of natural factors is connected with biological nature of a human and dependence from environment. Social factors are economic, social and political, organizational and leading as well as psychological and pedagogical and moral reasons of health activities.
So there are three united processes of a magnet of humans to lessons of physical exercises: 1) the process of external influence of a society on a person that is social orientation on health activities; 2) the external process of understanding a person an influence of natural or social environment that is orientation of health activities; 3) the result of orientation as the done motives that is social and valuable orientation on this activities. Abovenamed processes and phenomena are the social orientation on health activities; this activities is an influence of a society or social group on certain subject to appear social and valuable orientation on lessons of physical exercises and further development of physical culture as a whole.
At a mechanism of a social orientation the economic and social and political factors have a certain influence on forming given orientation. For providing their certain influence at a structure of social orientation there are special group of factors – factors of orientation on health activities. These factors are special organized actions which are complex reason of certain kind of relation to activities. When magnetizing a subject to lessons of physical exercises with the help of factors of orientation there are such stages: grounding for this subject a necessity at health activities; opening methods and means of its organization; understanding such activities themselves when taking part at it; working and widening results of all previous stages. Such for determinates a structure of factors of orientation according to their content and principle of directed action.

Purpose of the work: to study the dynamics of the indexes of maximal oxygen consumption in a one-year cycle of training in skilled runners who combine 800 and 400 m distances.
Methods and materials: theoretical analysis and generalization of literary sources, analysis of documentary materials, submaximal Valunda-Schestrand test (PWC170), pedagogical experiment and methods of mathematical statistics.
The research was conducted on the basis of the School of High School athletics of Kharkov. There were 5 boys and 5 girls who are 17-23 years old (4 - Candidates Master of Sports and 6 – athletes of the first category).
In the course of the work it was established that the indexes of maximal oxygen consumption of athletes is changing with the growth of their training. It was found that the boys’ level of maximal oxygen consumption changes more significantly in the process of their training than in the process of girls’ training. This can be explained by lower aerobic productivity (power), which is reflected in lower results of women in sports with predominant manifestation of endurance. This factor explains the relative reduction of record results with increasing distance. It is marked that under the influence of training loads of a special preparatory stage of the preparatory period, the indices of maximal oxygen consumption of girls did not change.

Relevance. In the physical education of students during the formation of individual physical culture is relevant to the issue of self-assessment of physical development, the study of motivation to engage in various types of physical activity among students.
The purpose of the work is to study the self-assessment of physical development and motivation in physical education among student youth in the process of formation of individual physical culture.
Methods: analysis and generalization of data of scientific and methodical literature and sources of the Internet; sociological methods; psychological and diagnostic methods; pedagogical methods; methods of statistical data processing. Experimental studies were conducted at Borys Grinchenko Kyiv University. The study involved students of 1-3 grades, 105 people (58 boys and 47 girls).
Results. In the course of the research, priorities were established in the motives and interests of student youth during physical education classes. The level of physical conditions of students according to the results of motor tests is determined.
The individual profile of the physical «I» of the individual is determined with the help of the test-questionnaire EM Bochenkova «Self-description of physical development», which is a modified version of the known method of A.M. Parishioners. It is established that at a low level of «self-esteem» students generally rate «coordination of movements», «endurance», «flexibility». With a low self-esteem of «sports abilities» and «physical activity», the studied students rate the «appearance» and consider themselves quite attractive. In general, the level of self-esteem on some scales increases with age («global physical self», «strength», «endurance»).
In order to form an individual culture of students’ health, it is necessary for the participants of the educational space to master the standards of self-preserving behavior and the culture of a healthy lifestyle to increase healthy activity. It is shown that students with a high level of physical fitness have higher scores on all indicators of the scale and they have a higher overall level of self-esteem. At the same time, students with a low level of physical fitness have an inflated self-esteem in relation to "appearance".

Published: May 2021

BACKGROUND
Surgical treatment of intractable epilepsy caused by porencephaly can be difficult because of poorly localizing or lateralizing electroclinical findings. The authors aimed to determine whether noninvasive evaluations are sufficient in these patients.

OBSERVATIONS
Eleven patients were included in this study. The porencephalic cyst was in the left middle cerebral artery (MCA) area in 9 patients, the left posterior cerebral artery area in 1 patient, and the bilateral MCA area in 1 patient. Interictal electroencephalography (EEG) revealed multiregional, bilateral, interictal epileptiform discharges in 5 of 11 patients. In 6 of 10 patients whose seizures were recorded, the ictal EEG was nonlateralizing. Nine patients underwent ictal single-photon emission computed tomography (SPECT), which revealed lateralized hyperperfusion in 8 of 9 cases. Fluorodeoxyglucose positron emission tomography (FDG-PET) was useful for identifying the functional deficit zone. No patient had intracranial EEG. The procedure performed was hemispherotomy in 7 patients, posterior quadrant disconnection in 3 patients, and occipital disconnection in 1 patient. A favorable seizure outcome was achieved in 10 of 11 patients without the onset of new neurological deficits.

LESSONS
Ictal SPECT was useful for confirming the side of seizure origin when electroclinical findings were inconclusive. Thorough noninvasive evaluations, including FDG-PET and ictal SPECT, enabled curative surgery without intracranial EEG. Seizure and functional outcomes were favorable.
Giant solitary extradural plasmacytoma of the skull: illustrative case
Authors: Castillejo Luis A. , de Jesús Julian José , González Pedro , Román Rafael 
Published: May 2021

BACKGROUND
Solitary extradural plasmacytoma of the skull (SEPS) is an extremely rare entity with only 35 cases reported in the English-language literature. SEPS is a rare presentation of plasma cell dyscrasias, accounting for 4% of plasma cell tumors. The diagnosis of solitary plasmacytoma requires exclusion of multiple myeloma (MM) and prompt diagnosis and treatment.

OBSERVATIONS
The authors describe the case of a 52-year-old man with SEPS. He presented with a painless, progressive, soft swelling mass in the left parietal region. Magnetic resonance imaging revealed a left frontotemporal extra-axial lesion that involved the ipsilateral orbital apex and posterior ethmoidal cells. Biological studies did not reveal features suggestive of MM. A diagnosis of SEPS was based on microscopic examination and immunohistochemical analysis after surgery. The patient had an excellent recovery and was discharged the day after surgery without neurological deficit.

LESSONS
SEPS is a potentially curable disease, and total resection with or without radiotherapy is associated with a good prognosis and long-term recurrence-free survival. Distinction between SEPS and MM is of paramount importance because the prognosis and treatment differ.

A New Dynamic Finite Element Formulation with Applications to Composite Aircraft Wings
Authors: Bomeman Stephen R. 
Published: May 2021

<p>This thesis presents a new dynamic finite element (DFE) formulation for the free vibration of composite wings modeled as beam assemblies. Implementing Euler- Bemoulli beam theory, the initially assumed uniform beam is modeled in a progressive manner to produce a complex tapered composite thin-walled wing. The DFE employs dynamic trigonometric shape functions (DTSF’s) to produce a single dynamic stiffness matrix containing both mass and stiffness properties. Then, the Wittrick-William root counting algorithm is used to solve the resulting non-linear eigenvalue problem. The effective stiffness of a flat fiberous composite beam is modeled using classical laminate theory. The effective stiffness of a thin-walled wing-box is achieved by employing a circumferentially asymmetric stiffness (CAS) configuration. The convergence of the DFE is significantly better as compared to other existing methods, the Finite Element Method (FEM) and the Dynamic Stiffness Matrix (DSM), particularly for complex elements and higher modes of free coupled vibration.</p>
A Spatial Model For The Spread Of Influenza Within The Human Respiratory Tract
Authors: Younis Nada P. 
Published: May 2021

<p>Several mathematical models with varying degrees of complexity are dedicated to charac-terizing influenza virus infection kinetics. The majority of existing mathematical modelsof in-host kinetics are based on ordinary differential equations (ODEs) and do not in-corporate viral transport modes. In this work, a spatial model was developed in orderto explore, for the first time, the effect of viral transport modesin-vivo: diffusion andadvection. Cellular regeneration and a simplified immune response were also included inthis model. Although severe and chronic infections sometimes occur in humans, most ofthe existing models can only reproduce seasonal infections. This new model has success-fully reproduced observed infection profiles within realistic biological parameters. Thechanges in parameters required to shift the infection kinetics from a seasonal to a chronicinfection, for example, is consistent with the factors believed to be responsible for theestablishment of such infections.</p>
Design And Analysis Of An Efficient And Reliable MAC Protocol For VANETS
Authors: Hafeez Khalid Abdel 
Published: May 2021

<p>The increase number of vehicles on roads and the immense number of fatal accidents they cause have driven the research and development of new generation technologies to help drivers travel more safely. One major cause of traffic accidents is that drivers cannot consistently respond to the changing road conditions appropriately. In fact, most accidents could be avoided if drivers could obtain and use relevant information of the traffic that is beyond their vision using wireless communications technology. Recently, the IEEE community adopted the IEEE 802.11p standard as a main technology for VANETs. To test the feasibility of this technology, most researchers use simulations toevaluate its new applications and protocols due to the prohibitive cost of implementing real VANET setup. Therefore, we first analyze VANET’s wireless channel analytically and bysimulations to predict its most appropriate propagation model and the communication rangethat minimizes the impact of the hidden terminal problem. Second, we derive a new mobility model that takes into account the vehicle’s follow-on safety rule, to accurately derive therelationship between vehicle’s speed and network density. It is expected that broadcasting and multi hop communications will be dominant in VANETs safety applications and protocols. Therefore, a Network Topology p-Persistence (NTPP) scheme is proposed to alleviate the impact of the broadcast storm problem. NTPPis based on vehicles’ knowledge of their neighbors in their range and traffic parameters to reduce the channel contention, redundant re-broadcasts and message travel time and to increase the emergency message reception rate.</p>
<p>We analyze the reliability of the IEEE 802.11p in VANETs safety and warning applications scope taking into consideration different factors. It is shown analytically and byextensive simulations that the current DSRC specifications may lead to undesirable perfor-mance under harsh vehicular environments. Therefore, a novel Distributed Multichanneland Mobility Aware Cluster-based MAC Protocol (DMCMAC) is proposed to alleviate theimpact of the hidden terminal problem, increase the network capacity and reliability. Clusterheads in DMCMAC are elected and re-elected in a distributed manner according to their relative speed and distance from their cluster members. The high stability of DMCMAC re-sults from its adaptability to drivers’ behavior on the road and its learning process to predictthe future speed and position of all cluster members using the fuzzy logic inference system.The reliability of DMCMAC is analyzed and compared with other protocols. It is shown by simulations that DMCMAC has high stability, its performance exceeds other protocols andcan achieve a timely and reliable delivery of emergency messages to their intended recipientswhich make it more suitable for VANETs.</p>
