Published: September 2023

This  paper  presents  a  methodology  for  generating  a  model  of  human  and  porcine  lumbar  spine  from  CT  Scans.  Nowadays,  the  use  of  CT  Scans  as  a  biomodeling  tool  is  a  technique  widely  used  in  the  development  of  computational numerical analysis based on Finite Element Analysis (FEA), thus  the  simple  and/or  complex  anatomical  structures  can  be  visualized  and  analyzed.  Thus,  the  relevance  of  this  paper  lies  in  the  fact  generation  numerical  analyses  biomechanical  with  results  very  close  to  experimental  analyses  creating  medical  solutions  in  the  design  of  prosthetic  devices.  Numerical results show a stress concentration in the intervertebral disc just in the end plates, both in the human case as in pigs, which is consistent with previous experimental analysis. Thus, it is concluded that the results obtained through this technique validate previous experimental analysis, however, it is necessary to take into account the characteristics the mechanical behavior of the different biological tissues that form the lumbar spine.
Molecular states of laterally coupled quantum dots under electric fields
Authors: Corredor Carlos Teofilo , Gutiérrez Willian
Published: September 2023

The states of a single electron trapped in two laterally coupled quantum dots are studied theoretically in the framework of the effective mass and envelope function approximations.  The electron tunneling between dots is studied by varying of inter-dot distance and we showed that the lateral quantum coupling between  them  allows  the  formation  of  molecular-like  states,  which  exhibit  similar  characteristics  to  those  of  a  molecule  H2+.  The  effect  of  an  in-plane  electric field on the energy spectrum is analyzed and our results reveal that the wavelength of photons emitted from the system can be tuned by simply applying a low-intensity electric field.  This latter feature is consistent with experimental observations.

Published: September 2023

In  this  paper  we  study  the  propagation  of  optical  pulses  by  the  finite differences method in a ridge waveguides structured for applications in optical transmission systems in the region of 1.55 μm. With the transformation of Maxwell’s equations its discrete formulation, for the system under study, and the appropriate boundary conditions was implemented an algorithm in Matlab that enables to visualize the behavior of the pulse when it propagates in the geometry of the waveguide studied. Variations in simulation were made in the wavelength, width of the core and the refractive index materials with which the results obtained were consistent with those reported in the literature. This study  allows  proposing  an  appropriate  geometry  and  materials  for  making  waveguides for applications in optical communications systems.
Asphaltenes and preasphaltenes from coal liquid extracts: feedstocks to obtain carbon mesophase
Authors: Barraza Juan , Muñoz Natalia , Barona Lina
Published: September 2023

The aim of this work was to produce mesophase by using preasphaltenes and asphaltenes from coal liquid extracts obtained in a Direct Coal Liquefaction (DCL)  process.  Preasphaltenes  and  asphaltenes  were  carbonized  at  inert  atmosphere  at  temperatures  of  350,  400  and  450  °C  during  180  min.  The  mesophase identification and quantification was performed by polarized light microscopy. The results showed that the highest concentration of mesophase (79% v/v), with mass yield of 12,4% w/w, was obtained from the asphaltenes treated at 400 °C. The highest mesophase global yield (with respect to coal fed) was 4,4% w/w.
Influence of the boundary conditions on FE-modeling of longitudinally stiffened I-girders subjected to concentrated loads
Authors: Graciano Carlos A. , Mendez José , Zapata Medina David G.
Published: September 2023

Longitudinally stiffened I-girders are commonly used to build incrementally launched steel bridges. During the bridge launching, the girders are subjected to concentrated loading at the support points. These loads are generally larger than those the structure would sustain once located in its final operating position. Numerical studies have considered girder segments subjected to concentrated loading where the boundaries are simulated by kinematic constraints. It represents rigid body conditions where elements at the supported end are allowed only to rotate about an axis perpendicular to the girder web. The load is applied on the girder flange along a small length compared to the total width of the evaluated segment. This paper is aimed at investigating the validity of this hypothesis for longer lengths of the applied load. Herein, the ultimate load of a stiffened girder is determined through finite element modeling, considering the boundaries conditions in two different ways: (1) considering kinematic constraints; and (2) simulating a transverse stiffener. In addition, the used model considers the plastic behavior of the material, the existence of imperfections in the web of the girder and the effects of large deformations. The results show that for short length loadings both hypotheses yield similar results. However, as the loading length increases, significant differences in the results are observed.
Transduction methods used on biosensors: amperometry and fluorescence
Authors: Cano Juan Bernardo , Buonasera Katia , Pezzotti Gianni
Published: September 2023

Biosensor devices have applications in a variety of fields as environmental analysis, biomedical, bio-defense, food and agriculture. On this kind of sensors, a biological material (known as biomediator) reacts with target analytes and an appropriated transduction system converts that reaction to an electrical signal that can be processed, saved and transmitted by using electronic systems.

 

In this article, two transduction methods used for biosensing applications are described: amperometry that is based on the measurement of the electron transfer occurring inside the biomediator and fluorescence, that is based on the measurement of the re-emitted light. Emphasis has been done on the electronics design, including component selection, useful circuit topologies and common problems and solutions. Electronics has been validated for the development of biosensor-based instruments characterized by low production costs and portability.

Authors: Chagoyén-Méndez César Alberto , Moya-Rodríguez Jorge Laureano , Álvarez-Peña Constantina , Muñiz-Acosta Yaidel
Published: September 2023

The  gearbox  of  a  wind  turbine  is  the  component  of  greatest  mechanical  complexity and is responsible for most wind turbines operational downtime and  for  increased  costs.  It  doesn’t  reach  a  20  years  projected  life.  All  the studies, until now, indicate that these failures arise from the design process. This  work  demonstrates  some  of  the  inadequacies  of  the  current  design  standards of wind turbines gearboxes, through the realization of a comparison of  the  results  of  the  calculation  of  the  helical  parallel  transmission  of  an  2,5  ME  wind  turbine,  carried  out  by  three  ways:  ISO  6336:2006  Method  B  and  AGMA  2101-D04  (Metric  Edition)  standards  and  by  using  numeric  simulation.  The  results  of  this  analysis  are  that  there  are  no  problems  of  strength  or  rigidity  in  both transmissions,  however  the  differences  between  these three calculation methods are considerable.
Hydrostatic pressure and magnetic field effects on the energy structure of D- ion confined in a toroidal quantum ring
Authors: Rincón Fulla Marlon , Suaza Yoder Alberto , Marín Jairo Humberto
Published: September 2023

The energy structure of a  ion, that is two electrons bound to a fixed donor impurity, imprisoned in a toroidal quantum ring is calculated as the full system is simultaneously under the presence of hydrostatic pressure probe and threading magnetic field. With the purpose of study the  energy properties; we have assumed very narrow quantum rings which allow us to use the well-known adiabatic approximation in order to decouple the fast motion in radial and axial direction from the slow rotation motion. The changes of the energy level-ordering and the crossover among the curves as a function of center line radius, donor position, and magnetic field are calculated for different values of the hydrostatic pressure. Finally, we contrast the results with those previously reported for limit cases.  From these comparisons it is possible to establish an excellent agreement among the different results which allow us to show the quality of the model implemented in the present work.

Authors: Garcés-Socarrás Luis Manuel , Sánchez-Solano Santiago , Brox Jiménez Piedad , Cabrera Sarmiento Alejandro José
Published: September 2023

This paper describes a library (XSGImgLib) that includes parameterizable blocks to implement low-level image processing tasks on FPGAs. A modelbased design technique provided by Xilinx System Generator (XSG) has been used to design the blocks, which implement point operation (binarization) and neighborhood operations (linear and non-linear filtering) in grayscale images. The blocks are parameterizable for input/output data precision, window size, normalization strategy, and implementation options (area versus speed optimization). The paper includes the implementation results obtained after fixing these options and exemplifies the combination of several blocks of the library to build a complete design for image segmentation purposes.
Effect of chloride salts on biodesulfurization process of a colombian coal
Authors: Caicedo Pineda Gerardo Andrés , Márquez Godoy Marco Antonio
Published: September 2023

A chloride salts medium was evaluated in biodesulfurization processes of a Colombian coal (2.34% total sulfur: 1.34% as pyritic, 0.90% as organic and 0.10% from sulfates), employing a consortium of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans. The process was carried out at three pulp concentrations (9.09%, 16.67% and 23.08%) and was compared with assays under similar conditions but containing modified T&K medium. All the tests were determined by measuring changes in soluble iron, pH, redox potential and microbial populations approach. Original and treated coal was analyzed by scanning electron microscopy with an energy-dispersive X-ray (SEM-EDX). For bioassays with chloride salts medium, the results showed above 70% of pyritic sulfur oxidation after 12 days, regardless of pulp concentration in contrast with results obtained for bioassays with a T&K modified medium where pulp concentration had influence and the pyrite oxidation was lower (below 55%).
Static and dynamic characteristics of turbulent flow in a closed compound channel
Authors: N. V. Goulart Jhon , T. M. Anflor Carla , V. Möller Sergio
Published: September 2023

The hot-wire anemometry technique was employed to study the velocity distribution and dynamic characteristics of the flow in two types of closed compound channels. The compound channels were built using two rectangular tubes attached to the walls of a wind channel separated by a distance d. In this configuration, a narrow gap is connected to a main subchannel. The results revealed an interesting flow that was quite similar to a mixing layer. All axial velocity profiles presented turning points at the main subchannel/ narrow gap interface. By using quantities from the mean flow velocity distribution, the flow could be described by a hyperbolic tangent function, and a Strouhal number was suggested as well. Regardless of the channel type, the dimensionless frequency was almost constant, resulting in a Strouhal number of approximately 0.10.
Photooxidation of anthracene under visible light with metallocarboxyphenylporphyrins
Authors: Díaz-Uribe Carlos Enrique , Vallejo-Lozada William Andrés , Martínez-Ortega Fernando
Published: September 2023

In this work, three novel carboxyphenylporphyrins (TcPP-M, M= H, Cu y Zn) have been synthesized and their efficiency in the photooxidation of anthracene under visible light (l> 500 nm) through generation of oxygen singlet (1O2) has been evaluated. The presence of 1O2 was evidenced by Electron Paramagnetic Resonance (EPR), where  it reacts with 2,2,6,6-tetramethyl-4-piperidone-N (TEMP) to produce 2,2,6,6-tetramethyl-4-piperidone-N-oxyl radical (TEMPO). The catalytic results indicated that the incorporation of the metal in the porphyrin ring strongly affects their efficiency on the anthracene oxidation. The TcPPH showed a higher photonic efficiency (31%) in the anthracene conversion than TcPPZn (13%) and TcPPCu (9%). This result may be related to the disruption of the planarity of the porphyrin ring. Finally the formation of anthraquinone and oxanthrone was detected as the oxidation products in the anthracene oxidation with 1O2.
State estimation technique for a planetary robotic rover
Authors: Iqbal Jamshed , Rehman-Saad Misbahur , Mahmood-Tahir Ahmad , Malik Ahsan
Published: September 2023

Given the long traverse times and severe environmental constraints on a planet like Mars, the only option feasible now is to observe and explore the planet through more sophisticated planetary rovers. To achieve increasingly ambitious mission objectives under such extreme conditions, the rovers must have autonomy. Increased autonomy, obviously, relies on the quality of estimates of rover's state i.e. its position and orientation relative to some starting frame of reference. This research presents a state estimation approach based on Extended Kalman Filter (EKF) to fuse distance from odometry and attitude from an Inertial Measurement Unit (IMU), thus mitigating the errors generated by the use of either system alone. To simulate a Sun-sensor based approach for absolute corrections, a magnetic compass was used to give absolute heading updates. The technique was implemented on MotherBot, a custom-designed skid steered rover. Experimental results validate the application of the presented estimation strategy. It showed an error range within 3% of the distance travelled as compared to about 8% error obtained from direct fusion.

Published: September 2023

Starting from the development that has reached the computational means in the last decades, the application of the numeric methods in the simulation of the interaction soil tillage-tool, has won in acceptance. As previous step, to the simulation of this phenomenon becomes necessary the definition of the models that predict with more accuracy the soil mechanical behavior. Taking into account these aspects the objective of present work is, to simulate the soil mechanical behavior in the soil-tillage tool interface by means of the finite element method. Starting from the employment of a model that is based on frictional approaches, with the inclusion of the adherence and the establishment of a tension of slip limit, as penalty to restrict the relative displacement between both surfaces. The models were implemented in the computational tool ABAQUS 6.4, starting from that which the soil-metal relative displacement was simulated. The results evidenced the validity of the model implemented to simulate the soil mechanical response in the soil-tool interface. The errors in the prediction of the soil stress oscillated from 1,45 to 5,45%, for the case of the soil vertical deformations it varied among 2,22 to 3,57%.
Physicochemical dynamics water in a tropical floodplain
Authors: Aguirre R. Néstor , Montoya M. Yimmy
Published: September 2023

We studied the physicochemical variables change in seven water swamps and seven streams outside the floodplain area Ayapel in nine samples during the period 2006-2009. The average value of electrical conductivity in the swamp is three times less than the value of the swamps of the region. 100 μS/cm can be considered as discriminating among swamps with lower values, and streams with higher values. There was no relationship between transparency and the concentration of photosynthetic pigments, which could be considered as an indicator a lower level trophic system. Temporary level all evaluated forms of nutrients present differences which indicates the importance of the effect of the pulse of flooding through the hydrological cycle. With the decline of the column of water in times of drought, there was an increase in the concentrations of nitrogen, which are favored by the resuspended material from the bottom of the swamp. Phosphorus concentration is most sensitive to spatial variation, this nutrient cycle is very associated with the sediments and the composition of the soil of each basin. We found that for the same phase in successive cycles of the pulse, there are differences in the system dynamics so that when the hydrologic sampling is performed is the main factor in the behavior of the physicochemical conditions of the system.

Authors: Szeremeta-Spak Marcia Danieli , Colmenero Joao Carlos
Published: September 2023

This paper proposes a model to support the decision-making process of selecting the location of a distribution center for the retail sector. The model was structured in two stages to consider objective and subjective criteria (multicriteria) for the decision-making process. In the first stage, a nonlinear programming model was used to establish a reference site in the region under analysis and identify five cities near that location. The second stage consisted of building a hierarchic structure for making decisions based on criteria and sub-criteria relevant to the process of deciding the location of a distribution center, and applying the Analytic Hierarchy Process (AHP) multicriteria method for all five previously selected candidate cities. The model was used to define the location of a distribution center for a furniture and appliance retailer in the state of Paraná, Brazil. The results show that the criteria transportation and market have the most influence in the decision-making process, and that the best alternative for the distribution center was the city of Arapongas (PR). The methodology proved to be efficient in the decision analysis presented herein.

Due to the recent and significant growth of the information technology (IT)  services, industries need some sort of framework and / or standards for the  management of their services, especially IT services. So, it becomes necessary  and essential to define and adopt a set of best practices for providing and  effectively managing the technology and services offered throughout its life  cycle. Currently, the management of IT applications and services becomes  more  complex.  Predicting  and  controlling  the  problems  associated  with  system  performance  and  capacity  planning  has  become  a  difficult  task.  For  large  IT  projects,  the  costs  related  to  performance  tuning,  performance   management and capacity planning, generally turn out to be the biggest and  the most uncontrollable costs. In recent years, a number of frameworks aimed  at  covering  certain  issues  of  IT  service  management  have  been  developed.   One of these issues is the IT service capability management. In this paper, a  comparison between the models and standards used today regarding capacity  management are presented. A comparison of the strengths and weaknesses  of each of the models/standards on the capacity management is presented,  so that it can guide organizations to select the model/standard that best suits  their needs.

Since the beginning of science, motivation for the search of knowledge was simple curiosity. However, nowadays the relationship between science and society has changed. Currently, conducting high quality research in some areas requires expensive equipment and very qualified staff, forcing researchers to compete fiercely for the limited resources and for a greater recognition. The pressure to publish research papers, and the lack of resources, has led to the detrimental of quality and ethics concerns of the published works, sometimes falling into scientific misconducts such as: scientific fraud (misrepresentation in data and results or manipulation thereof, plagiarism), unethical (fictitious authorship, repeated publications) and negligence in publishing (bibliographic mistakes).

Authors:   Taras Shevchenko National University of Kyiv, Ukraine, Omelchenko Nadiia , Kurapov Anton ,   Taras Shevchenko National University of Kyiv, Ukraine
Published: September 2023

Background. As a result of the military attack in Ukraine, both the military and civilian population are facing mental health disorders such as post-traumatic stress disorder (PTSD), depression, anxiety, and panic attacks. Classical psychotherapy and psychiatry are often ineffective in treating these conditions. In the United States and Europe, a significant amount of research is being conducted on psychedelic-assisted therapy and its potential psychotherapeutic impact on the treatment of depression and PTSD, especially in cases where traditional treatments are not effec¬tive. Given this, it may be extremely beneficial for Ukraine to consider an alternative treatment for PTSD and depression, such as psychedelic- assisted therapy. Our study emphasizes the importance and relevance of this issue. Goal. To reveal the features of psychedelic-assisted therapy and meditative experience as factors of personal changes, such as anxiety level, subjective well-being, overall life satisfaction, and self-awareness. Methods. The design of this study is combined: it includes quantitative and qualitative methods. The independent variables were experience in psychedelic-assisted therapy, experience in meditation, and experience in both practices; the dependent variables were anxiety, subjective well-being, general life satisfaction, and self-awareness. The total sample was 33 people. Results. Meditation and psilocybin therapy improve the emotional state and psychological well-being of the subjects, in particular, they promote focus, inner peace, self-awareness, reduction of anxiety and depression, as well as self-knowledge and self-development. Conclusions. Meditation and participation in PAT reduce anxiety. Respondents who meditated and participated in PAT had lower levels of anxiety compared to other groups. Participation in PAT increased the level of subjective well-being the most. Participation in PAT and meditation increase self-awareness. Respondents who engaged in these practices had a higher level of self-awareness compared to the group that only meditated. Respondents assess the effectiveness of the therapy as high and sustainable. They note significant changes in their lives, such as relief of depression symptoms, improved cognitive function, changes in attitudes toward themselves and others, and increased energy and decision-making ability. Thus, participation in PAT and meditation is advisable for people who have low levels of self-awareness and subjective well-being and want to increase them, and high levels of anxiety and depression and want to decrease them.

Published: September 2023

A large body of studies on the choice of educational trajectories is aimed at identifying the role of the family, socio-economic status, and place of residence. But the psychological patterns of preferences for educational trajectories have received less attention. Current study is aimed at identifying motivational predictors. The study presents an analysis of data obtained from 1914 schoolchildren studying in 9 classes, living in the urban (952 people) and rural areas (962 people) aged 14 to 16 years (M=15.33, SD=0.49), 57% - girls. As a result of the study, it was found that the orientation towards higher education is determined by both intrinsic and extrinsic motivation. Orientation to receive secondary vocational education is associated with amotivation and alienation from study. Schoolchildren living in rural areas tend to settle down and are more oriented towards education, both secondary vocational and higher.
Continuity in the Interpretations of Legal Relationships in the Case of Unjustified Enrichment
Authors: Khamidullina F. I. , Galimov A. Sh.
Published: September 2023

The paper provides a theoretical justification of some substantive constructions that have constituted the civilistic heritage of the past periods and have laid the basis for the modern interpretation of legal relations concerning unjustified enrichment. The paper analyzes the continuity in the development of legal relations regarding the concept of unjustified enrichment. The author has shown that legal relations on unjustified enrichment are of systemic importance for the current law and order. They are located in a very extensive legal field of claims aimed at compensation for damage, and they represent civil law relations of a protective type. Being a real social phenomenon and, at the same time, a civilistic category, legal relations in unjustified enrichment can be analyzed: a) from the standpoint of economics; b) from a legal standpoint; c) from the standpoint of justice (they should coincide with legal standings, which in practice is not always achievable). Continuity in the interpretations of legal relations concerning unjustified enrichment expressed in the dynamics of their historical and legal development provides variability, gradual complication of forms and, at the same time, the constancy of the basic ethical and legal idea of the prohibition of unjustified enrichment. Markers of continuity include: 1) the general principle underlying the corresponding obligation; 2) formal and substantive criteria for determining the groundlessness in the enrichment process; 3) possible tools (forms, methods and means) for the protection of violated rights. Defining each of the listed elements in relation to a particular stage of the economic and legal development of society, we get a general picture of continuity, which for prognostic purposes can be extrapolated to the perspective of the development of the institution of a version claim in the domestic legal system.
An Individual as a Foreign Agent: The Legal Regulation
Authors: Dolgiev M. M. , Dolgieva M. M.
Published: September 2023

Foreign interference in Russia’s internal political processes is almost always disguised as the constitutional right of citizens to ideological diversity, forming public opinion, provoking panic, as well as influencing the attitude of society towards governmental authorities. The influence of individuals who form public opinion on the basis of their recognition and pseudo-authority has significantly increased. A large-scale spread of social networks has caused a dramatic increase in the popularity of artists, musicians, public figures, whose statements can encourage society to make certain decisions. The study is conducted in order to identify signs of foreign influence, as well as criteria for classifying individuals as foreign agents. Based on a comparative analysis of the legislation on foreign agents in Russia and the United States, the authors establish the conditions for the need to restrict the constitutional rights of citizens in order to maintain a balance of private and public interests. In the preparation of the article, formal and logical methods were used, as a result of which the authors analyze socio-legal phenomena that allowed to identify the relationship between increased foreign influence and consolidation of domestic legislation on foreign agents as a response. The authors come to the conclusion that in order for an individual to be acknowledged as a foreign agent under Russian law, three elements are needed: the presence of foreign influence, the participation of an individual in political activity and direct or indirect influence on state bodies or state policy. At the same time, the main problem of law enforcement is the distinction between real foreign agents and unpatriotic citizens who actively oppose the policy of the state, which can be used «blindly». In this regard, a wide application of the provisions of the Law on Foreign Agents is justified, and the assignment of the status of a foreign agent is subject to individualization.
State Ideology as a Mandatory Feature of the Constitutional State
Authors: Krotov A. V.
Published: September 2023

The recent history of Russian state building is directly connected with numerous, and not always successful, attempts to formulate state ideology. Such attempts at «ideological search» intensified with the adoption of amendments to the Constitution of Russia in 2020. Despite a number of scientific works devoted to the problems of the formation of state ideology, today in the Russian legal doctrine the polarity of opinions regarding the content of state, national, constitutional ideology has not been eliminated, which, in turn, affects the process of development of the state and law. The purpose of this work is to identify the reasons for the consolidation in Part 2 of Article 13 of the Constitution of the Russian Federation of the prohibition on the establishment of any ideology as state or mandatory. It also aims to formulate a number of terms related to the research topic, resolve the competition between state ideology, national, constitutional and ideology of the ruling group.The paper uses such methods of scientific research as synthesis, abstraction, generalization. The author analyses the works of E. Y. Barkhatova, V. I. Yakunin, P. A. Astaficheva, N. S. Bondar, E. E. Barinov, V. V. Lazarev, B. S. Ebzeeva, and other authors.The results of the study consist in the formulation of the author’s interpretation of a number of terms: national ideology; state ideology; constitutional ideology; ideology of the ruling group. The interrelation of the state ideology and the national ideology, as well as the ideology of the ruling group, is shown. Separately, the principles of the formation of national ideology are disclosed, the features of the state ideology in the USSR are shown. The results of the research can be used in the science of constitutional law, the general theory of state and law, political science.
Using the International classification of functioning, disability and health to describe children with Down syndrome
Authors: Kolcheva Julia A. , Nepomnyashchaya Svetlana A. , Adrianov Andrey V.
Published: September 2023

BACKGROUND: Down syndrome is a widespread, but still insufficiently studied genetic pathology, leading to early disability of the child population.
Complex habilitation using transcranial micropolarization according to the method of N.Yu. Kozhushko can effectively compensate for impaired cerebral functions. The article deals with the question of the expediency and relevance of the application of the International classification of functioning, disability and health ICF in the complex habilitation in Down syndrome in children, as an international language intended for a comprehensive description of the components of human health.
AIMS: studding the possibilities of transcranial micropolarization in the correction of neurological deficit in children with Down syndrome based on the principles of the ICF, designed to comprehensively describe the biopsychosocial status of a child.
MATERIAL AND METHODS: The study involved patients (n=55) with Down syndrome aged 3 to 5 years without severe concomitant decompensated pathology from other organs and systems. All cases of the disease were genetically confirmed: all had complete trisomy on the 21st chromosome. The main group included 40 children, the control group 15. In addition to the complex psychological and speech therapy support, the habilitation program for the children of the main group included the method of transcranial micropolarization according to the method of N.Yu. Kozhushko, the use of which can significantly improve the existing cerebral dysfunction in Down syndrome. All children were categorical ICF profiles, taking into account the most sensitive and informative in this disease.
RESULTS: According to the results of testing on a 10-point scale for assessing speech function, 6 months after the procedures, there was a significant improvement in the indicators of expressive and impressive speech, speech attention, as well as positive dynamics in the formation and improvement of neatness skills.
At the same time, the ICF made it possible to form a categorical profile of a child with Down syndrome, visually assess the influence of environmental and personal factors in each specific case, objectify changes in health disorders during habilitation, which is especially important in assessing the patients condition, developing a treatment plan, and analyzing the results obtained.
CONCLUSIONS: The method of transcranial micropolarization adapted by N.Yu. Kozhushko, can be recommended for complex habilitation for patients with Down syndrome. The use of the ICF for a comprehensive assessment of the functioning of a child with a hereditary disease makes it possible to take into account the strengths and weaknesses of the individual, correct environmental factors, which is especially important in achieving results in hereditary diseases accompanied by cerebral deficiency.

Published: September 2023

BACKGROUND: Assessment of the need for medical and social and long-term care for elderly and senile people serves as the basis for improving organizational approaches to improve the quality of medical and social services provided.
AIMS: Determination of the needs of elderly and senile people in the provision of medical and social assistance.
MATERIALS AND METHODS: For the study, a representative selective set of 400 elderly respondents is determined, of which 280 (70.0%) respondents lived at home (I group) and 120 (30.0%) under the stationary conditions of the gerontological center (II group). The study was conducted by interviewing based on a specially designed questionnaire and Loneliness by Svetlana G. Korchagina. Statistical processing of the received data was carried out using the Microsoft Office Excel 2013 and statistical package Statistica 12.
RESULTS: The average age of the respondents was 72.97.96 years (p 0.05). The presence of polymorbidity was noted by every third respondent (33.0%), of which 23 diseases had 26.0%, 4 or more 7.0%, with a prevalence in the structure of the incidence of diseases of the cardiovascular system. 53.0% of people are in need for medical and social home care. 31.0% of people were satisfied with medical care, 41.0% of people consider social assistance available. A high prevalence of the state of loneliness in elderly and senile people was established: 94.0% in group I, 99.0% in group II, with a progressive increase in the rate as the age of the elderly increases.
CONCLUSIONS: With increasing age, the subjective self-assessment of health worsens, associated with an increase in polymorbidity (mainly age-associated diseases) and the presence of disability; the decrease in the possibility of self-care increases the need for the elderly for assistance and care. The high prevalence of self-assessment of loneliness among the elderly and senile causes an increased need for older people in psycho-corrective measures.

BACKGROUND: The analysis of sleep patterns in patients with chronic disorders of consciousness is attracting increasing attention in terms of diagnosis, prognosis, and treatment of severe brain damage. The study describes a software package based on an artificial intelligence (AI) expert system designed to classify the phases and stages of sleep, taking into account the characteristics of impaired cortical rhythm in such patients.
AIM: To develop a specialized AI-based software package focused on patients with chronic impairment of consciousness for automatic classification of sleep phases and stages, with an emphasis on identifying sleep spindles and non-rapid eye movement (REM) and REM sleep phases.
MATERIALS AND METHODS: To ensure the correct operation of the software package, receiver operating characteristic (ROC) curves were analyzed considering the binary classification of slow sleep, REM sleep, and wakefulness.
RESULTS: The average sensitivity and specificity of the algorithm were 87.9 and 70.1, respectively. The average area under the ROC curve was 0.790. The algorithm for determining the REM phase demonstrates low specificity with high sensitivity, and its graph was similar to that of wakefulness, as well as the irregularity of the presence of REMs in the REM sleep phase in patients with CNS and the frequent presence of nystagmus in the waking state. Information about the presence of nystagmus, entered at the start of the program, allowed us to slightly increase the efficiency of the algorithm; however, this aspect probably needs further improvement.
CONCLUSION: A software package that takes into account the features of electroencephalography of patients with chronic disorders of consciousness and analyzes sleep and wakefulness automatically is not only useful as a diagnostic tool for neurologists and somnologists but also contributes to a wider dissemination of this technique in clinical practice.

A Contribuição da Política Jurídica na Construção da Tributação Ambiental
Authors: Lima Bilkis Maria Barbosa
Published: September 2023

A legislação ambiental brasileira tem por espoco disciplinar ações de proteção e prevenção ao meio ambiente o que a torna uma das mais completas do mundo, porém não tão eficaz, pois apresenta falhas em seu cumprimento que compromete a sustentabilidade ambiental. Indaga-se como a Política Jurídica poderia contribuir para dar maior eficácia às normas ambientais. Desse modo, objetivou-se analisar de forma reflexiva a importância da Política Jurídica, na construção de uma política tributária capaz de fomentar práticas ambientalmente corretas, a partir da perspectiva do direito que deve ser. Sendo o objeto de preocupação da Política Jurídica a identificação da norma justa e útil para determinada situação, serve de fundamento para justificar a tributação ambiental em um momento em que afloram as discussões sobre a premente necessidade de preservação do ambiente natural. No desenvolvimento do trabalho os fundamentos da Política Jurídica foram apresentados, tratou-se da eficácia das normas ambientais e da utilização dos tributos como ferramenta indutora da sustentabilidade ambiental. E, por fim, observou-se que ainda são poucos os resultados de práticas ambientalmente corretas, mas que provavelmente mais efetividade terá a atuação normativa se estiver alinhada à dinâmica das necessidades sociais ao invés de pautar-se unicamente no estabelecimento de parâmetros ideais de disciplinamento social.

AbstractBrazilian environmental legislation has the purpose of disciplinary actions for the protection and prevention of the environment, which makes it one of the most complete in the world, but not so effective, as it has failures in its compliance that compromise environmental sustainability. The question is how legal policy could contribute to making environmental standards more effective. The objective was to reflectively analyze the importance of Legal Politics, in the construction of a tax policy capable of promoting environmentally correct practices, from the perspective of the law that should be. The object of concern of legal policy is the identification of a fair and useful rule for a given situation, what's the use to justify environmental taxation at a time when discussions about the pressing need to preserve the natural environment arise. In the development of the work were presented the fundamentals of Legal Politics, the effectiveness of environmental norms and the use of taxes as a tool to induce environmental sustainability. Finally, it was observed that there are still few results of environmentally correct practices, but that normative action will probably be more effective if it is aligned with the dynamics of social needs instead of being based solely on the establishment of ideal parameters of social’s disciplining.

O presente artigo teve como objetivo o estudo de normas que autorizaram o compartilhamento de dados por empresas de telefonia com entidades governamentais, para fins de suporte à produção estatística oficial durante a situação de emergência de saúde pública decorrente do novo coronavírus. A pesquisa analisou as justificativas do Poder Público para coleta, compartilhamento e monitoramento de dados sem a devida autorização dos usuários ou mecanismos de proteção e segurança capazes de evitar e combater acessos não autorizados, vazamentos acidentais ou utilização indevida. Através de pesquisas doutrinárias e interpretações sobre a ciência jurídica, ficou afastada suposta antinomia entre normas relacionadas ao poder de vigilância sanitária e as garantias constitucionais do direito à liberdade e à autodeterminação da informação. A método utilizado nesse estudo foi realizada de forma exploratória, associada à pesquisa bibliográfica e legislativa, além de levantamentos de dados governamentais e informações disponíveis em redes públicas e privadas sobre o tema. O direito à privacidade e a garantia do sigilo de dados não podem ser violados pelo monitoramento e compartilhamento de dados, sem que haja plena segurança técnica e transparência na forma de sua utilização, pois a proteção dos direitos fundamentais deve ser priorizada em relação aos novos engenhos tecnológicos.

AbstractThis article aimed to study the rules that authorized the sharing of data by telephone companies with governmental entities, in order to support the official statistical production during the public health emergency situation resulting from the new coronavirus. The research analyzed the Government's justifications for collecting, sharing and monitoring data without the proper authorization of users or protection and security mechanisms capable of preventing and combating unauthorized access, accidental leaks or misuse. Through doctrinal research and interpretations of legal science, the supposed antinomy between norms related to the power of health surveillance and the constitutional guarantees of the right to freedom and self-determination of information was ruled out. The method used in this study was carried out in an exploratory way, associated with bibliographical and legislative research, in addition to surveys of government data and information available in public and private networks on the subject. The right to privacy and the guarantee of data secrecy cannot be violated by monitoring and sharing data, without full technical security and transparency in the way it is used, since the protection of fundamental rights must be prioritized in relation to new devices technological.
