Published: April 2019

Introdução: A mielomeningocele (MMC) é definida como o não fechamento adequado do tubo neural durante a embriogênese, acomete em média 1 a 6 em cada 2000 nascidos vivos. Objetivo: Avaliar o modelo experimental de mielomeningocele (MMC), induzido pelo ácido retinóico (AR) e ácido valpróico (AVP), quanto à ocorrência das principais malformações do fechamento do tubo neural, dentre elas a MMC. Métodos: Foram utilizados fetos de ratos distribuídos em 3 grupos: Grupo retinóico - Fetosprovenientes de ratas que receberam dose única de AR via oral no décimo dia de gestação em doses crescentes de 60mgIKg a 120mg/kg, diluída em óleo vegetal na concentração de 8mg/ml, Grupo valpróico – Fetos provenientes de ratas que receberam 2 - 3 doses de AVP via peritoneal no oitavo dia de gestação em doses crescentes de 1350mglKg a 3000mg/Kg e Grupo controle- Fetos de ratas que receberam somente água destilada. No vigésimo primeiro dia de gestação, os animais foram submetidos à eutanásia em câmara com éter e laparotomia para retirada dos fetos. Os fetos foram, inicialmente, examinados externamente para determinação de alterações macroscópicas de malformações de coluna vertebral e da cauda. Resultados: O modelo ARapresentou resultados que permitem o seu emprego no estudo das malformações da coluna vertebral e outras malformações associadas. No entanto, o modelo AVP não se mostrou viável para a indução de tais malformações.

Targets of Psychological Work for High Alexithymia People
Authors: Gaus Emma V , Pronenko Evgeny A , Vasilyeva Olga S
Published: April 2019

The article reviewed the modern empirical studies of alexithymia, summarized the theoretical understanding of the phenomenon of alexithymia, describes the difficulties faced by the people with a high level of alexithymia and suggested tips on psychological work with the alexithymic people. The novelty of this research consists in the formulation of the aspects of the practical work of a psychologist in order to increase the level of the adaptation of the alexithymics and improve the quality of their life. At the moment, this problem is covered in only a small amount of research. The main result of the article is the identification of the areas of psychological work with the alexithymics: (1) the improvement of the connection with the body; (2) the correction of personality problems; (3) the psychological assistance in the harmonization of the interpersonal relations. It has been shown that disrupted connection with the body is one of the most significant problems of the alexithymics and the factor which contributes to the development of psychosomatic diseases. For the improvement of the connection with the body the authors suggest such types of psychological work as the differentiation of physical feelings, a fuller understanding of the body map, the ability to control the condition of the body, the acceptance of the body and the increase in the satisfaction with it. The ways of working with the most significant personality problems of the alexithymics are singled out (correction of non-adaptive coping-strategies, low level of life satisfaction, rigidity, and instability of the emotional sphere). The areas of work on improving the relations of the alexithymics with the surrounding people are highlighted (gaining more knowledge about the emotional sphere, working with friends and relatives, teaching communication skills, taking into account the influence of alexithymia). Finally, the conclusion is made about the importance of the integrated psychological work with the people with a high level of alexithymia in order to develop the specific tools for comprehensive assistance to alexithymics.
Tax policy, tax disharmony and tax competition: The situation of Greek economy
Authors: Karagiorgos Alkiviadis , Drogalas George , Lazos Grigorios , Fotiadou Ioanna
Published: April 2019

The European Union is a unique economic and political union, a single "internal" market with over than 510 million inhabitants. Further coordination in the field of taxation is required, since it is not yet integrated into the E.U. policy and remains under the responsibility of national governments. However, the economic and financial turmoil caused by the crisis of 2008 and the new challenges resulted from the globalization and digitalization of the economy, require profound reforms to tax systems. Thus, fiscal policy is a significant priority on the EU agenda: firstly, in order to stabilize public finances, stimulate growth and competitiveness and finance the European social welfare model as well as to tackle tax evasion and aggressive tax planning, developed mainly by multinationals. The present paper attempts to explore on a theoretical and empirical basis the challenges and possible developments towards harmonization in European taxation, at a critical juncture, not only for the integration but also for the existence of the European Union. More specifically, it investigates the Greek taxation and its structural weaknesses through empirical research conducted with questionnaires distributed among 225 tax officers, accountants, and accounting executives and statistical processing of their response. The results were examined through descriptive analysis, segmented in seven theoretical domains based on the examination of both audit literature and the present taxation state of Greece. The findings reveal that structural problems remain unresolved within the Greek tax system. However, it is understood that issues of distrust toward the taxation system may hinder harmonization processes.
Extended Dai-Yuan conjugate gradient strategy for large-scale unconstrained optimization with applications to compressive sensing
Authors: Esmaeili Hamid , Rostami Majid , Kimiaei Morteza
Published: April 2019

We present a new spectral conjugate gradient method based on the Dai-Yuan
strategy to solve large-scale unconstrained optimization problems with
applications to compressive sensing. In our method, the numerator of
conjugate gradient parameter is a convex combination from the maximum
gradient norm value in some preceding iterates and the current gradient norm
value. This combination will try to produce the larger step-size far away
from the optimizer and the smaller step-size close to it. In addition, the
spectral parameter guarantees the descent property of the new generated
direction in each iterate. The global convergence results are established
under some standard assumptions. Numerical results are reported which
indicate the promising behavior of the new procedure to solve large-scale
unconstrained optimization and compressive sensing problems.
Natural reason and the ontologization of the metaphysics in Aquinas
Authors: Milidrag Predrag
Published: April 2019

The aim of the article is to analyze and to affirm two theses. First, to show
that, for Aquinas, the existence of God is not the condition for the
metaphysics as a science and, second, that the Thomistic metaphysics leads
to the notion of being (ens) which is the fundament of all acts of
knowledge. To show that we analyze Aquinas?s theory of knowledge. That
entails the discussion on the order in the knowledge, the short analysis of
the rational soul and the role of the judgment in Aquinas?s metaphysics.
Finally, we investigate the technical and the methodological tool which
Aquinas calls via resolutionis and its role in the understanding of
Aquinas?s notion of ens as a fundament of any knowledge.
Crisis of replicability of results in contemporary experimental psychology in the light of the criteria of replicability in contemporary physics
Authors: Perovic Slobodan
Published: April 2019

Since 2010, the impossibility of replicating experimental results (published
in leading journals in the field) in a number of repeated psychological
experiments began to be increasingly perceived as a methodological crisis.
Replicability is generally considered to be the basic standard of scientific
experiments, modeled on exemplary classical experiments in the field of
physics. But the conditions of replicability vary depending on the studied
phenomenon in physics itself, and therefore the criteria for the adequacy of
the experiment vary as well. Three characteristic examples of experiments we
analyze led to three different epistemic attitudes of their adequacy based
on the replicability of the results. We argue that these attitudes can be
relevant in understanding the nature of the crisis of replicability in
psychology.

Authors: Santos Tamires Dias dos , Souza Ana Paula Ramos de , Londero Angélica Dotto , Machado Fernanda Prada , Cunha Maria Claudia
Published: April 2019

Objetivos: Analisar a presença de risco psíquico em um grupo de crianças pequenas com queixa de atraso de linguagem, em uma perspectiva interdisciplinar entre psicanálise e teoria enunciativa de linguagem, comparando a análise clínica a partir de distintos instrumentos de avaliação. Método: Pesquisa qualitativa de estudo de cinco casos na faixa etária de dois anos a quatro anos e quatro meses, com queixa de atraso de linguagem. O psicodiagnóstico foi realizado pela psicóloga através do IRDI-questionário, Childhood Autism Rating Scale(CARS) e Avaliação Psicanalítica dos Três anos(AP3), e a avaliação da linguagem foi realizada pela fonoaudióloga através da análise de vídeos, a partir dos princípios enunciativos. Resultados: As avaliações AP3 e IRDI-questionário demonstraram que os cinco casos tiveram ou têm risco psíquico, mas a avaliação de base psicanalítica foi mais sensível aos diferentes tipos de risco. A CARS detectou um caso de autismo. A visão enunciativa de avaliação da linguagem permitiu observar a relação entre aspectos psíquicos e funcionamento de linguagem, sobretudo quando considerado o processo de semantização da língua e o princípio da intersubjetividade. A intervenção precoce realizada pelo fonoaudiólogo pode diminuir risco psíquico quando atravessada pelas teorias psicanalítica e enunciativa. Conclusão: As teorias psicanalítica e enunciativa foram complementares na detecção de risco psíquico e avaliação de linguagem nos casos de atraso na aquisição da linguagem, demonstrando que seus instrumentos foram efetivos na diferenciação diagnóstica.

Effect of organic acid concentration in lubricant on tribological characteristics of friction couple
Authors: Burlakova V. E. , Drogan E. G.
Published: April 2019

Introduction.The possibility of using monocarboxylic acids as a lubricant composition additive, and the effect of their concentration in lubricant on the evolution of the friction factor of a brass-steel couple, as well as the morphology of the film surface under friction is considered. The work objective is to study the effect of the concentration of carboxylic acids in the lubricant composition on the evolution of the friction factor of copper – steel alloy.

Materials and Methods.Tribological studies of a brass-steel friction couple in aqueous solutions of monocarboxylic acids with the concentrations of 0.025; 0.05; 0.1; 0.2; 0.5 mol/l are carried out. Using scanning electron microscopy, we have studied the morphology of the servovite film surface that is formed on a steel disk after frictional interaction of a brasssteel couple in aqueous solutions of acids with the concentration of 0.1 mol/l.

Research Results.Tribological characteristics of the brasssteel tribocoupling in aqueous solutions of carboxylic acids of various concentrations are studied. The optimum acid concentration in the lubricant composition is specified. Herewith, a selective transfer and a wearless friction regime are implemented under friction of the brass 59–steel 40X couple. A decrease in the friction ratio to 0.009 and 0.007 is found out under friction in aqueous solutions of valeric and caproic acids, respectively. The formation of an anti-friction film on the steel surface is identified through the scanning electron microscopy. It is established that the film formed in an aqueous solution of caproic acid has a denser structure in comparison with the film formed under friction in aqueous solutions of butyric and caproic acids.

Discussion and Conclusions.Thus, the tribological studies of a brass-steel friction couple in aqueous acid solutions show that the optimum molar acid concentration in the lubricant composition is 0.1 mol/l. At this acid concentration, the values of the friction factor characteristic of the wearless mode are attained.

Authors: Eliseev S. V. , Mironov A. S. , Vuong Quang Truc
Published: April 2019

Introduction.The dynamic interaction features in mechanical oscillating systems, whose structure includes additional couplings, are considered. In practice, such cases occur when using various optional mechanisms and motion translation devices under the formation of technical objects. The study objective is to develop a method for constructing mathematical models in the problems of dynamics of the mechanical oscillating systems with optional devices and features in the system of external disturbing factors.

Materials and Methods. The techniques used to study properties of the systems and the dynamic effects are based on the ideas of structural mathematical modeling. It is believed that the mechanical oscillating system, considered as a design model of a technical object, can be compared to the dynamically equivalent automatic control system. The mathematical apparatus of the automatic control theory is used.

Research Results.A method for constructing mathematical models is developed. The essential analytical relations for plotting oscillating systems are obtained, which enable to form a methodological basis for the integral estimation and comparative analysis of the initial system properties in various dynamic states. Dynamic properties of the two-degree-offreedom systems within the framework of the computer simulation are investigated. The implementability of dynamic oscillation damping mode simultaneously in two coordinates with the joint action of two in-phase kinematic perturbations in the mechanical oscillating systems is shown.

Discussion and Conclusions.The possibilities of new dynamic effects, which are associated with the change in the system structure under certain forms of dynamic interactions, are noted. The study is of interest to experts in machine dynamics, robotics, mechatronics, nano and mesomechanics.
Study on stationary solutions to the problem of phytoplankton dynamics considering transformation of phosphorus, nitrogen and silicon compounds
Authors: Belova Yu. V. , Atayan A. M. , Chistyakov A. E. , Strazhko A. V.
Published: April 2019

Introduction.The solution to the problem of transformation of phosphorus, nitrogen and silicon forms is studied. This problem arises under modeling phytoplankton dynamics in shallow-water bodies including the Azov Sea. The phytoplankton dynamics model is formulated as a boundary value problem for the system of diffusion-convection-response equations and takes into account the absorption and release of nutrients by phytoplankton, as well as the transition of nutrients from one compound to another. To calculate the initial conditions and parameters of the equations under which the steady-state regime occurs, the software is developed, which is based on the model describing changes in phytoplankton concentrations without considering current effects. This model is represented by a system of inhomogeneous differential equations. Based on the developed software, the initial conditions and parameters of the phytoplankton dynamics model in the Azov Sea are calculated experimentally.

Materials and Methods.A 3D model of phytoplankton dynamics is considered taking into account the transformation of phosphorus, nitrogen and silicon compounds based on the system of nutrient transport equations. The case of a spatially uniform distribution of substances is considered to specify the parameters of the model at which the stationary modes occur. Because of simplification, a system of ordinary differential equations solved through the Runge-Kutta method is obtained.

Research Results. The software is developed to specify the initial conditions and parameters of the phytoplankton dynamics model considering the transformation of phosphorus, nitrogen and silicon compounds. Several numerical experiments are performed under the assumption that the development of phytoplankton is limited by a single biogenic substance. As a result of the computational experiment, it can be seen that with the obtained values of the initial concentrations and parameters of the equations, stationary modes occur for the system of ordinary differential equations describing the case of the spatially uniform distribution of substances.

Discussion and Conclusions.The mathematical model of the transformation of phosphorus, nitrogen and silicon forms in the problem of phytoplankton dynamics is studied. Stationary  modes for the system of ordinary differential equations are obtained, for which the values of the system parameters and initial conditions are determined. The results obtained can be used in further simulation of the phytoplankton dynamics considering the transformation of phosphorus, nitrogen and silicon compounds with account for convection-diffusion, salinity, and temperature.

Published: April 2019

Introduction. It is shown that the digital twin (electronic passport) of a CNC machine is developed as a cyber-physical system. The work objective is to create neural network models to determine the operation of a CNC machine, its performance and dynamic stability under cutting.

Materials and Methods. The development of mathematical models of machining processes using a sensor system and the Industrial Internet of Things is considered. Machine learning methods valid for the implementation of the above tasks are evaluated. A neural network model of dynamic stability of the cutting process is proposed, which enables to optimize the machining process at the stage of work preparation. On the basis of nonlinear dynamics approaches, the attractors of the dynamic cutting system are reconstructed, and their fractal dimensions are determined. Optimal characteristics of the equipment are selected by input parameters and debugging of the planned process based on digital twins.

Research Results. Using machine learning methods allowed us to create and explore neural network models of technological systems for cutting, and the software for their implementation. The possibility of applying decision trees for the problem of diagnosing and classifying malfunctions of CNC machines is shown.

Discussion and Conclusions. In real production, the technology of digital twins enables to optimize processing conditions considering the technical and dynamic state of CNC machines. This provides a highly accurate assessment of the production capacity of the enterprise under the development of the production program. In addition, equipment failures can be identified in real time on the basis of the intelligent analysis of the distributed sensor system data.

Layer-based Privacy and Security Architecture for Cloud Data Sharing
Authors: Gupta Ishu , Singh Niharika , Singh Ashutosh Kumar
Published: April 2019

The management of data while maintaining its utility and preservation of security scheme is a matter of concern for the cloud owner. In order to minimize the overhead at cloud service provider of applying security over each document and then send it to the client, we propose a layered architecture. This approach maintains security of the sensitive document and privacy of its data sensitivity. To make a balance between data security and utility, the proposed approach categorizes the data according to its sensitivity. Perseverance of various categorization requires different algorithmic schemes. We set up a cloud distributed environment where data is categorized into four levels of sensitivity; public, confidential, secret, top secret and a different approach has been used to preserve the security at each level. At the most sensitive layers i.e. secret and top secret data, we made a provision to detect the faulty node that is responsible for data leakage. Finally, experimental analysis is carried out to analyze the performance of the layered approach. The experimental results show that time taken (in ms) in processing 200 documents of size 20 MB is 437, 2239, 3142, 3900 for public, confidential, secret and top secret data respectively when the documents are distributed among distinct users, which proves the practicality of the proposed approach.

An Interdisciplinary Approach of Activist Technologies: the Case of the Leaflets of the Mobilization Against-CPE of 2006. As it a neglected boundary object of the scientific fields, the leaflet is most often relegated to a simple tool for illustrating political struggles, overlooking the viewpoint of its materiality, of its manufacturing and dissemination, and the multiplicity of its uses. Based on a PhD dissertation of 2014 about the leaflets of a french student protest, the one called against-CPE of 2006, the aim of this article is showing how an interdisciplinary approach can help to build a methodology to collect, define and analyze the multiple facets of this still relatively unknown activist technology.
ÉTUDE DES CRISES POLITIQUES INTERNATIONALES ET INTERDISCIPLINARITE : LE CAS DU 11 SEPTEMBRE 2001
Authors: MESZAROS Thomas , MORIER Clément
Published: April 2019

Interdisciplinarity and International Political Crisis Studies: the Case of 9/11. This study aims to work the concept of political crisis using interdisciplinary tools. It is based on a case study, the crisis of the September 11 attacks, analyzed according to two complementary approaches. First, the breakdown of the sequences of this crisis makes it possible to identify the development of the intensity of the phenomenon over time, and its phases, in order to observe the behavior of the different types of actors involved in the crisis. Then, we have to study the dynamic morphology that shapes the deployment of the crisis, from the point of view of the aggressor, but also from the target, using René Thom’s Catastrophe Theory. This accounts for the internal functioning of these actors, and also, shows crisis management opportunities for the target of these attacks. The purpose of this work is to put forward the relevance of interdisciplinarity to think political crises, and to put interdisciplinarity into practice in order to improve the knowledge of a phenomenon in a specific field (political crisis), by studying with another one.

Published: April 2019

In this study, we conducted a study based on the possibility that expressing anger in organization could lead to positive effects as well as negative effects, and compared when expressing anger and receiving other’s anger. This study is divided into Study 1 and Study 2. and the purpose of Study 1 was to construct questionnires on the ways of anger expression and the effects of anger expression in organizational settings. As a result, the ways of anger expression were divided into linguistic anger expression and behavioral anger expression. The effect of anger expression was divided into a positive level and a negative level. The purpose of Study 2 was to examine the relation between the ways of anger expression and the effects of anger expression and the moderating effect of self-consciousness through the items constructed in Study 1. Results of analysis of the data from 271 organizational members are as follows. First, expressing anger was positively related to both positive and negative effects of anger expression, and receiving anger was positively related to the negative effects of anger expression. Second, Self-consciousness significantly moderated the relationship between the receiving anger and the effect of anger expression. Second, Self-consciousness had a moderating effect on receiving anger on the effect of anger expression. Specifically, the moderating effect of private-public self consciousness was statistically significant in the effects of receiving anger on the positive effect of anger expression.

Serum concentrations of creatinine, potassium, phosphorus, and BUN before surgery positively correlated with duration and maximum severity of POD. Absolute changes in serum concentrations of creatinine, potassium, and BUN from before surgery to after surgery positively correlated with POD duration. Cats with anuria before surgery had longer POD than did other cats; however, there was no difference in POD duration or maximum severity with unilateral versus bilateral ureteral obstruction. Thirty-four of 37 (92%) cats survived to hospital discharge, which was not associated with whether ureteral obstruction was unilateral or bilateral. Azotemia resolved in 17 of the 34 (50%) cats that survived to hospital discharge.

CONCLUSIONS AND CLINICAL RELEVANCE

Results of the present study indicated that several factors were associated with POD duration and maximum severity, alone or in combination, and that with intensive management of fluid and electrolyte derangements, regardless of the extent of the original azotemia, a high percentage of cats survived to hospital discharge.
Domestic Debt and Economic Growth in Nigeria: An ARDL Bounds Test Approach
Authors: Ibrahim Ayuba K. , Khan Shazida Mohd
Published: April 2019

The study examines the long-run relationship between domestic debt and the fiscal policy of economic growth in Nigeria in the period from 1981 to 2013 owing to government reforms in the financial system, particularly due to the establishment of the Debt Management Office (DMO) in 2000 and a new fully funded pension fund scheme, both of which resulted in a resurgence of the debt market. The issue that is often raised is the doubt regarding the stability of the debt and its likely implications for the economy, as well as the unpleasant consequences for the government embarking on consolidation. The study employs the autoregressive distributed lag (ARDL) approach and the bounds test as proposed by Narayan (2005), anchored on the perspective of the endogenous growth theory. The results reveal that although overall the adverse negative domestic debt hurts the economy, it has a positive effect on the total aggregate government revenue and economic growth in Nigeria in the research period. Furthermore, the paper develops a system to assess the speed of the adjustment mechanism coefficient in an error correction model (ECM).
Spontaneous regression of severe aortic stenosis after massive embolization in a patient with antiphospholipid syndrome
Authors: Youssef Ali , Alrefae Mustafa , Abouelsoud Sayed
Published: April 2019

We present a case of probably unreported aortic stenosis evolution in a patient with primary antiphospholipid syndrome (APS). A female patient, 54 years old, with a history of recurrent deep venous thrombosis, an episode of pulmonary embolism and was positive for APS antibodies. She was kept on warfarin and aspirin. The patient was admitted with acute pulmonary edema and severe aortic stenosis. While preparing for aortic valve surgery, the patient developed acute stroke, and a week later developed concurrent acute ischemia of both lower limbs. Emergency surgery salvaged the lower limbs and follow up transthoracic echocardiography showed marked regression of the thickening of the aortic valve leaflets, only mild aortic stenosis and moderate aortic regurgitation. Aortic valve surgery was cancelled, and the patient was kept on warfarin and aspirin.

Conclusion

Development of severe aortic stenosis is uncommon in primary APS, and this scenario of spontaneous improvement from a severe to a mild aortic stenosis, is probably unreported before.

Authors: Rovira Ferrer Irene
Published: April 2019

El objetivo principal del presente trabajo es el análisis de la reducción prevista en la base imponible del ISD en el caso de la adquisición mortis causa de la vivienda habitual del causante, tanto a nivel estatal como autonómico y foral. Así, además de valorar su viabilidad y estudiar las precisiones que derivan de una realidad compleja, se analizarán los diferentes conflictos normativos que aparecen y que, en algún caso, llegan a ser susceptibles de inconstitucionalidad, acabando con algunas propuestas de mejora para su reformulación.
IDENTIFICAÇÃO DE MICRO-ORGANISMOS PATOGÊNICOS EM SANITÁRIOS E BERÇÁRIOS DE UMA CRECHE
Authors: MENDES Elena Carla Batista , KOZUSNY-ANDREANI Dora Inês , MARTINS Carmem Costa
Published: April 2019

Banheiros utilizados por crianças em creches abrigam uma diversidade de micro-organismos, com potencial de se tornarem um veículo de disseminação de doenças. Além da natural vulnerabilidade desses segmentos etários, a creche representa um ambiente coletivo que proporciona grande circulação e transmissão de agentes patogênicos. O presente estudo teve como objetivo identificar micro-organismos patogênicos nos sanitários e berçários em uma creche. Foram coletadas amostras em uma creche do município de Santa Fé do Sul – SP. Na coleta utilizou-se swab na parte interna dos banheiros e berçários como: pia, cuba, torneira, trocador, assoalho, vaso e maçaneta, em seguida, colocados em tubos de ensaio com solução salina a 0,9% esterilizada, após esse procedimento, as amostras foram inoculadas em meios de cultura. Foram identificados micro-organismos patogênicos. Os resultados sugerem que os micro-organismos presentes nos banheiros e berçários da creche representam riscos à saúde das crianças e dos funcionários, caso não ocorra uma higienização sistemática e adequada.

Authors: Sereno Cabral Yhanna Porto , Araujo de Carvalho Claudia Reinoso , Villaça Gonçalves Monica
Published: April 2019

El objetivo de esta revisión fue identificar las tendencias de los estudios más recientes en el área de Terapia Ocupacional en Geriatría y Gerontología, teniendo como base dos revistas brasileras de Terapia Ocupacional. La metodología empleada fue la revisión de alcance de artículos publicados entre 2010 y 2015 en las revistas Cadernos Brasileiros de Terapia Ocupacional y Revista de Terapia Ocupacional da Universidade de São Paulo. Los artículos identificados se analizaron a partir de las principales temáticas que abordan, definidas después de revisar su contenido: instrumentos evaluativos y protocolos; formación profesional; enfoques, técnicas y recursos terapéuticos; cuidadores de adultos mayores. Se concluye que, a pesar del pequeño número de publicaciones, el área ha sido abordada de diversas formas por los terapeutas ocupacionales, reflejando diferentes posibilidades de actuación, aunque enfocadas en el campo de la salud. Se señala que existen brechas que requieren ser llenadas, especialmente en lo que se refiere a la comprensión del proceso de envejecimiento como un fenómeno social.
Subjetividades, interseccionalidades e implicaciones en la investigación e intervención ocupacional con madres adolescentes
Authors: Cortina Roa Luz Ángela
