Application of the institutional approach in the problem field of the philosophy of education
Authors: Sahuichenko Valentyna Volodymyrivna
Published: April 2019

Purpose. The study is purposed to determine the civilization-significant trends in the development of educational institutions and the cultural forms of their organization in modern sociocultural contexts.

Research methods. The research was carried out within the framework of the neoinstitutional approach to the analysis of the structures of modern education using the system-theoretical method introduced by N. Luhmann and developed by his followers, and the methodological foundations of synergetics. In analyzing the organizational and cultural forms of educational institutions, a phenomenological method is preferred, complemented by methods of historical genetic and structural-functional analysis. The cultural and anthropological component of the study, especially the task of justifying the conditions of the universality of educational institutions, required the involvement of hermeneutic and dialectical methods in its methodological program, as well as methods of anthropological interpretation and anthropological reduction.

Theoretical basis. The author proceeds from the unsatisfactory vision of the transformations of educational institutions in Ukraine that occurred during the years of independence and focused primarily on the search for alternative forms of education, rather than on strengthening the competitiveness of the national education system, which sprays its resources and promotes social stratification of society. The destruction of the image of Ukrainian education acquires a systemic character, weakens educational institutions, destructively affects the world of life of institutions and deforms pedagogical relations.

Scientific novelty. The author proves the need to develop, on the basis of an integrated methodology, the procedural concept of educational institutions, the transformation of which takes place not only outside, but also according to the internal logic of their organizational and cultural forms, and provides educational contingent reforms.

Conclusions. The theory of modern educational institutions should explore not only their functional potential, but also predict the moments of their dysfunctionality, the dialectic of stabilization and destabilization of the education system as a result of its institutional changes. In contrast to the study of the self-organization of educational institutions in modern cultural and social anthropology of the biologically compensatory direction, the transition from statics to the procedural understanding of educational institutions makes it possible to consider them as conditions, resources and practices of self-transcendence of man, society and culture, and pathology, if institutionalized traditionalism emerges beyond the self-sufficiency of tradition and instead of creative self-realization of personality suggests using mechanisms of social and cultural cloning.
Cognitive Foundations for Educational Strategies
Authors: Dobronravova Iryna
Published: April 2019

New Age connected education with science, which is understood as a rational project. Science of New Age is principally public. Connected with it the ideal of objective truth claims the rational description of scientific methods. Historical transformation of ideals and types of rationality changed also the educational strategies of New Age. Foundations of such strategies are the foundations of scientific cognition: ideals and norms of scientific research, scientific world picture and philosophical foundations of science. 

Traditions are extremely strong in education, but critique of them and understanding, that education must be changed, proclaim themselves very soundly today, particularly in jubilee report by Club of Rome “Come on!” For members and supporters of Ukrainian Synergetic Society, the ideas, expressed in report of Club of Rome, are consonant to their synergetic imaginations about complex self-organizing world and to view on modern stage of development of science as on postnonclassical one. Methodological principles of postnonclassical science are contrast to reductionism, postnonclassical world picture is based on dialectic ideas of becoming and wholeness, postnonclassical type of rationality approves objectiveness of knowledge by taking into account the human values of researchers.

Specificity of objects of postnonclassical science is brunching of nonlinear dynamics of self-organizing systems. It needs to elaborate in education process the certain cognitive orientations. Partially such orientations were formulated in methodological principles of nonlinear thinking, which orient to be ready for emergence of a new whole as a result o self-organization.

Current nonlinear scientific world picture considers the processes of self-organization of all levels of world's structure organization as condition of its existence. Understanding of such processes requires the elaboration of evolutionistic holistic worldview. Of course, learning of modern nonlinear theories can't be the task of common education. It is important, that readiness to favorable reception of evolution and holistic ideas is elaborated in process of such education.
The Natural Medium as Carrier of Meanings and Their Decoding by Living Beings: Biosemiotics in Action
Authors: Knyazeva Helena
Published: April 2019

The synthetic, integrative significance of biosemiotics as a modern interdisciplinary research program is under discussion in the article. Aimed at studying the cognitive and life activity of living beings, which are capable of recognizing signals and extracting the meanings, biosemiotics serves as a conceptual node that combines some important notions of theoretical biology, evolutionary epistemology, cognitive science, phenomenology, neuroscience and neurophilosophy as well as the theory of complex adaptive systems and network science. Worlds of perception and actions of living beings are built in the process of co-evolution, in structural coupling and in enactive interaction with the surrounding natural environment (Umwelt). Thereby the biosemiotic theories developed by the founders of biosemiotics (J. von Uexküll, Th. Sebeok, G. Prodi, H. Pattie) are conceptually closed to the system-structural evolutionary approach developed in synergetics by H. Haken and S.P. Kurdyumov, the conception of autopoiesis (H. Maturana and F. Varela), second-order cybernetics (H. von Foerster), the conception of enactivism in cognitive science (F. Varela, E. Thompson, A. Noë). The key to comprehending the processes of extracting and generating meanings is that every living organism lives in the subjectively built world (Umwelt), so that its Umwelt and its internal psychic organization become parts of a single autopoietic system. According to the well-known expression of G. Bateson, information is a not indifferent difference or a difference that makes a difference. Differences become information when a cognitive agent as an interpreter, acting as part of an autopoietic system, sees signs in these differences that make meanings.
Evolution of Representations of Complex Self-Organizing Environments/Systems in the Humanities at the Abroad of the XX-XXI centuries
Authors: Kozobrodova Diana
Published: April 2019

This article examines issues related to the transformation of ideas about self-organization in humanities in Ukraine at the turn of the 20th and 21st centuries. These ideas about processes of self-organization of complex systems that developed initially within the framework of natural science knowledge (physics, chemistry, biology) go beyond the framework of natural science methodology and become an interdisciplinary field of research in which many fundamental problems of the humanities in the field of social philosophy, sociology, psychology and philosophy of education. And this transition is not gradual, but spasmodic, which allows us to talk about the synergetic paradigm, established today in modern Ukrainian humanity. If in the 90's. in Ukraine there are only two pioneering monographs (I.S. Dobronravova, I.V. Yershova-Babenko), devoted to the philosophical and methodological analysis of the main synergistic categories (self-organization, non-linear thinking, complexity, etc.), at the moment such monographs in the humanities (philosophy, sociology, psychology, etc.) are already numerous. Moreover, the main synergistic concepts and categories used in the field of natural science knowledge in the new research area not only found application, but were significantly expanded and transformed. Thus, ideas about self-organization that arose in physics, chemistry, and other natural sciences were applied to complex self-developing objects in the social and human sciences, which allowed developing a new methodological tool that is characterized by universality, transversality, polyphonicity, flexibility and holistic approach to the object of research. This toolkit responds to modern transformations and transitions existing in global cultural and historical reality, represented by such concepts as "globalization", "information-communicative revolution", or "informationalism" (Castells). Thus, at the turn of the XX-XXI centuries in Ukraine, the study of complex self-organizing environments / systems in the social and humanitarian sphere starts from the positions of the synergetic methodology as a general scientific research program.
Art and Bioethics: Shift/Fusion of Understanding Genres
Authors: Hubenko Hanna
Published: April 2019

A fusion of «bioethics» and «art» changes the means and ways of broadcasting art in the field of new biotechnological achievements and recalls responsibility in science. Bioethics socializes art. Art popularizes bioethics and complements its «experience of comprehension» with aesthetic experiences. The article analyzes the connections that unite bioart with science and bioethics. Examples of creative bioart projects at the World Congresses on Bioethics, which draw attention to the installation and performative forms, expressing the artistic experience of bioethical values and meanings that museums and other public fields represent, are given. The processes of forming links between laboratory research (often hidden from public attention) and art-works through practical experiment, dialogue, observation, or play are analyzed. The tandem of art and bioethics provides a link between scientists and the public, reveals new possibilities for ethical reflection, and represents a living manifesto of overcoming the disunity of scientific and everyday practices. Art and bioethics are sources of inspiration for each other. Not only does art expand its boundaries, transforming a scientific experiment into an artistic process, but also bioethics is entering a new level of research and discussion, reinforcing its creative potential through art. Despite the fact that they differ in genre, they create a common space of rational discourse as well as a common ground for familiarizing with the artistic experience in the process of their cooperation and communication, with the purpose of understanding the emerging problems, attracting to them not only professionals, but also broad circle of people interested in bioethical issues.

Authors: Dobronravova Iryna , Gorbunova Lyudmyla
Published: April 2019

Under this title, a meeting of the Round Table organized by the Ukrainian Synergetic Society was held within the framework of the scientific-practical conference "Innovations in Education: Value-Competence Approach", held on May 29, 2018 at the Dragomanov National Pedagogical University.

Participants: I. Dobronravova, L. Gorbunova, I. Drach, L. Bevzenko, L. Bogataya, I. Yershova-Babenko, I. Knysh, N. Kochubey, T. Bilous, O. Komar, Y. Melkov, M. Nesterova, A. Pipich, L. Sidorenko.

Traditionally, for such meetings, the role of moderator was performed by the president of the Ukrainian Synergetic Society, Professor Iryna Dobronravova. The participants expressed views on a certain resonance of the theses of the Rome Club with the ideas of synergetics: a call to abandon reductionism and linear thinking, recognition of a holistic approach to understanding the current situation on the planet and developing an action plan for favorable prospects, calling for synergy of action and a balance of sustainable development , call for disciplinary complementarity in research and training.

It focused on the philosophical foundations of the necessary transformation of thinking, which should become integral, on the ideas of the “new Enlightenment”, the “global citizenship” policy, education strategies as “literacy about the future”, which is based on connectivity, universal values ​​and respect for cultural differences, focuses on sustainable development, on education, which comes from the pluralism of content and is inclusive, that is, it includes the whole range of contradictory and complementary perspectives, not limited to analytical, but cultivates integral thinking.

It is concluded that this report is certainly of great methodological importance for educational research and educational policy, especially in clarifying the problems of sustainable (balanced) development, globalization, internationalization and the development of a global civil society. Education for sustainable development and its component - education for global citizenship are relevant in the context of the problems posed by this report of the planetary development of humanity.
Absolute vs. relative speed in high-frequency trading
Authors: Virgilio Gianluca Piero Maria
Published: April 2019

This paper addresses the little investigated topic of the relationship between the speed of exchange servers, an absolute reference for the system, and trading speed, considered relative to the former. This is a major issue, as trading speed overwhelming the capability of the server to cope with the incoming orders might jeopardise the orderly functioning of the markets. It will be shown how, by raising the speed of trading and increasing the number of the agents operating in the market, it is possible to generate a crisis, no matter how performing the exchange server is.

The paper presents a theoretical framework and then verifies its occurrence by analysing audit trail data. The theoretical framework shows a scenario in which under certain, heavy but by no means uncommon, conditions, the excess speed of the trading agents with respect to servers is capable of exacerbating price volatility, leading to vicious feedback loops capable of potentially creating a financial crisis. The empirical part analyses data taken from a particularly volatile day and compares them with much less volatile days. It results that, because of excessive speed, one of the most widely used techniques for minimising risk, order churning, can cause a major crisis.

This paper explores and compares the policies of these three countries, with the hope of conceptualizing a more inclusive policy that incorporates the voices of those who work within the sex industry.
Children of Heaven
Authors: Kawchuk Olenka
Published: April 2019

Ruling over western South America for nearly 100 years, the Inca Empire was one of many global cultures that practiced human sacrifice, though few other rituals of human sacrifice are as captivating as the Inca child sacrifice of capacocha. Capacocha children were chosen to be representatives of the Inca people in the afterlife. As such, they were afforded an elevated position in society before their death. Following their selection, children would undergo a year-long pilgrimage terminating at a mountain top shrine where they would be killed. As a result of the low temperature and oxygen levels present at such a high elevation, the bodies of capacocha children were protected against decomposition, creating some of the best-preserved natural mummies in the world. These mummies have been the subject of numerous bioarchaeological analyses to determine their age, sex, geographic origin, pathological conditions, diet, and cause of death. Beyond these, however, the mummies present a unique opportunity to study how the capacocha ritual process — including the sudden ascension in status — manifested itself on the children's bodies. This paper aims to review the bioarchaeological data garnered from the mummies in order to reconstruct the experience of a child chosen for capacocha. Results suggest higher variability between children selected for capacocha than was originally outlined by Spanish chroniclers.

Authors: Chakraborty Dr. Saumik , Bhattacherjee Dr. Sharmistha , Das Dr.  Dilip Kumar , Dasgupta Dr. Samir
Published: April 2019

Background & objectives: Developmental delay is a condition where a child fails to reach the different developmental domains at the expected age. Children who are developmentally delayed are less likely to be productive adults. The present study is aimed to determine the prevalence and predictors of global developmental delay among the infants of rural areas of Siliguri sub division, Darjeeling district, West Bengal

Methods:  A descriptive epidemiological study with cross- sectional design was carried out among 780 infants in Siliguri subdivision, Darjeeling district, West Bengal. Thirty cluster sampling technique was used to select the study subjects. Data were collected by interviewing the respondents using a pre-designed and pre tested schedule. Development status was assessed using ASQ-3 scale and delay in more than one domain was defined as global developmental delay. Logistic regression was applied to find out the association between global development delay and different predictors.

Results:  Overall prevalence of global developmental delay was 38.2%. Neonatal factors like birth weight (p=.000), h/o neonatal infection (p=.001) and neonatal jaundice (p=.000) was found to be significantly associated with global developmental delay. No statistical significance was observed with sociodemographic and maternal factors.

Conclusion:  Developmental delay is high among the infants of the studied area and associated with some of the neonatal factors. Field based studies using appropriate screening tools from different parts of India including West Bengal will be helpful to find out the hidden cases and related factors.

О спектре отраженного излучения от быстрых нейтронов, падающих на бетонную стенку
Authors: Загороднюк Алексей , Гацкевич Георгий , Миненко Виктор , Кутень Семен Адамович
Published: April 2019

Проведено компьютерное моделирование спектра отраженного излучения моноэнергетического пучка нейтронов, падающего на бетонную стену. Рассмотрены два встречающиеся на практике варианта падения нейтронов, которые могут быть использованы для оценки защиты от отраженных нейтронов в помещениях: перпендикулярно слою и под углом 45° к нему. Спектр отраженного излучения содержит пики, обусловленные упругим рассеянием нейтронов на ядрах элементов, входящих в состав бетона. Пики идентифицированы с элементным составом бетона. По амплитуде преобладают пики, соответствующие элементам с наибольшим содержанием в бетоне. Показано, что вследствие рассеяния пиковые значения в наибольшей степени смещаются в низкоэнергетическую область при нормальном падении пучка нейтронов.

SYNTHESIS AND OPTICAL PROPERTIES OF MESOMORPHIC GLASSY NANOCOMPOSITES BASED ON CADMIUM CAPRYLATE WITH CdSe / ZnS HETERONANOPARTICLES
Authors: Mirnaya Tatiana , Yaremchuk Galina , Kosheliev Alexander
Published: April 2019

The paper presents on the synthesis and optical properties of mesomorphic composites, based on a glassy liquid-crystalline caprylate matrix, with  CdSе/ZnS hetero-nanoparticles. The synthesis of complex core-shell semiconductor nanoparticles was carried out by fusing together a cadmium caprylate composite with CdSе nanoparticles and zinc caprylate composite with ZnS nanoparticles. The cadmium and zinc chalcogenide nanoparticles have been synthesized in molten cadmium caprylate and zinc caprylate respectively.

It has been found by optical spectroscopy that the have hetero-nanoparticles a core-shell structure. The effect of the composition (molar ratio of the components) of CdSе/ZnS hetero-nanoparticles on their spectral characteristics has been studied. It has been shown that the nanocomposites with hetero-nanoparticles are characterized by a more intense exciton fluorescence band than composites with individual CdSе or ZnS nanoparticles. It has been found that by varying the hetero-nanoparticle composition, one can change the core-shell thickness ratio and adjust thereby the absorption and emission band edge. As the number of ZnS nanoparticles in CdSе/ZnS hetero-nanoparticles increases some narrowing of the long- wavelength emission region first takes plase, which may be attributed to a reduction in the recombination of the smaller number of surface trapped exciton, and then, at a large ZnS content, a broadening of the long- wavelength emission region takes plase due to the extended CdSе/ZnS surface.

It has been found that the main  contribution to the exciton fluorescence of nanocomposites with CdSе/ZnS hetero-nanoparticles is made by cadmium selenide nanoparticles, and that zinc sulfide nanoparticles enhance exciton fluorescence, also due to decrease in surface emission. It has been shown that the nanocomposites with hetero-nanoparticles are characterized by a more intense exciton fluorescence band that the nanocomposites with individual CdSе.

Authors: Shteinberg Leon Yakovlevich
Published: April 2019

The catalytic synthesis of benzanilide by the interaction of benzoic acid with aniline is an important model reaction of direct catalytic amidation that has been intensively developed recently in the field  of the concept of «green chemistry», and its study is an urgent task.

     In the framework of solving this problem the effect of the final product - benzanilide, and its substituted on catalysis by tetrabutoxytitanium and its partial hydrolysis products (polybutoxytitanates) was studied. With an increase in the concentration of the preliminary addition of benzanilide, the initial rate of catalytic interaction of benzoic acid with aniline decreases monotonically.

     Benzanilide itself does not catalyze the amidation process, does not hydrolyze under reaction conditions by water, and does not undergo other changes in the reaction mass.

     The kinetics of the formation of benzanylide in the presence of additives of a number of substituted benzanilides, containing electron-withdrawing substituents, showed higher values ​​of the reaction rate constants as compared to that for the formation of benzanilide in the absence of any additives. This suggests the presence of two routes of catalysis: the coordination route (polarization of the carbonyl group of the benzoic acid due to the interaction with the atom of titanium) and acid route. The latter can be associated with the formation of complexes due to the coordination of the titanium atom of the catalyst with the carbonyl group of the substituted benzanilide, the appearance of a relatively acidic NH=group and catalysis of conjugate acid: the titanium-containing catalyst + the corresponding substituted benzanilide.

     The formation of such a catalytic complex, by the example of a pair of benzanilide + tetrabutoxytitanium, was confirmed by the NMR 1H spectroscopy method.

     Catalysis of aniline acylation with benzoic acid in the presence of additions meta= and para=substituted benzanilides correlates well with the Hammett equation with two straight line segments with ρ=0.478 and ρ=-0.235, with a maximum, indicating a different effect of substituted benzanilides containing electron-donating and strong electron-withdrawing substitutes on the complexation with tetrabutoxytitanium and polybutoxytitanium and the change in their catalytic activity.

     The decrease in the rate of the catalytic formation of benzanilide is especially pronounced with the addition of ortho=substituted benzanilides, containing strong electron-withdrawing substituents, which at the same time have a high steric effect.

This paper presents the study of mixed-ligand complexes of Ln(III), which are used as volatile precursors in CVD processes for the preparation of lanthanide-containing films and coatings. New mixed-ligand acetylacetonate complexes of lanthanides (III) with acetic (propionic) acid and acetonitrile or dimethylformamide were synthesized and investigated by physic-chemical methods of analysis (elemental analysis, differential thermal analysis, IR spectroscopy, powder X-ray diffraction). Using mixed-ligand complexation, the properties of the initial lanthanide β-diketonates (in particular, chemical and thermal stability) can be changed significantly.

To assess the stability of the synthesized mixed-ligand complexes, their quantum-chemical modeling was performed using the semi-empirical method Sparkle/PM7. Standard changes of the Gibbs energy ∆G0298 were calculated for the solution reaction of (1) synthesis of mixed-ligand complexes and (2) substitution of one of the β-diketonate ligands in the Ln(III) tris-acetylacetonates dihydrates by an acetate ion or propionate ion. The ∆G0298 values for the syntesis reaction mainly increases with increasing donor basicity and decreasing ionic radii Ln(III) in the La>Gd>Lu series. For all mixed ligand complexes of Ln(III), the heats of formation are negative, which indicates their thermodynamic stability in solution.

It was established that the obtained complexes have the same composition of the general formula [Ln(AA)2·L·2D], where Ln (III) = La, Gd; НАА- acetylacetonе; L - anion of acetic (HAc) or propionic (HРrop) acids, D- acetonitrile (AN), dimethylformamide (DMFA).

The results of the thermal analysis confirm the computational data: in the case of the lanthanum mixed-ligand complexes, the carboxylic acid is coordinated to the central ion through bridging carboxylate-ions, which contributes to the formation of oligomers. The lanthanum mixed-ligand complexes are not volatile due to their oligomeric structure. On the other hand, similar gadolinium complexes are monomeric and sublimate at 180 - 350 °C.

The reaction of pyrazolo[1,5-a]pyrazine-4(5H)ones with phosphorus tribromoxide in boiling benzene yielded 4-bromopyrazolo[1,5-a]pyrazines, and the thionation with phosphorus pentasulfide in pyridine at 90 °C led to pyrazolo[1,5-a]pyrazine-4(5H)thiones. The synthesized bromine derivatives are electrophilic, and thiones are nucleophilic substrates. Their subsequent structural modification in the first case was carried out by interaction with thiophenols, and in the second case was conducted with functional halogenoalkanes. It was shown that bromides react with substituted thiophenols in dimethylformamide in the presence of potassium carbonate at 90 °C to form 4-arylthiopyrazolo[1,5-a]pyrazines with yields of 65–83 %. 4-S-methyl-functionalized derivatives of pyrazole[1,5-a]pyrazines with yields of 60–78 % were easily obtained by the alkylation of pyrazole[1,5-a]pyrazin-4(5H)thiones with a-bromoketones, bromoacetic acid, ethyl bromoacetate and bromoacetonitrile in the K2CO3—DMF system at room temperature. The composition of all synthesized compounds is in agreement with the results of elemental analysis and mass spectra. Their structure is confirmed by NMR 1H and 13C spectra. In particular, in the NMR 1H spectra of 4-arylthiopyrazolo[1,5-a]pyrazines, in addition to the characteristic signals of the pyrazole and pyrazine nuclei, signals of protons of thioaryl substituents are present in the range of 7.04 –8.05 ppm, and in NMR spectra of the 1H 4-S-methylfunctionalized derivatives of pyrazole[1,5-a]pyrazines signals of exocyclic methylene protons are present at 4.11– 5.02 ppm. Promising derivatives with antibacterial activity against the test cultures S. aureus (MIC = 7.8 g/mL), M. luteum (MIC = 3.9 g/mL), and antifungal activity against the test culture of fungus A. niger (MIC = 7.8 g/mL) were determined among 4-S-substituted pyrazole[1,5-a]pyrazines as a result of studies of the antimicrobial activity.

Authors: Etcheverria Teresa Cristina , Santos Wagner Ferreira
Published: April 2019

Este artigo, oriundo de uma pesquisa em andamento, se propõe a discutir a produção escrita de estudantes do 1º ano do Ensino Médio em atividades que envolvem o conceito de função. O estudo está fundamentado na ideia de que a análise da produção escrita dos alunos também pode ser vista como uma metodologia de ensino (CURY, 2008). A coleta de dados foi realizada por meio de atividades aplicadas aos alunos do 1º ano do Ensino Médio de uma escola do interior do estado de Sergipe. Neste trabalho são discutidos apenas os dados obtidos na aplicação das atividades voltadas para o conceito de função. Os resultados revelam que poucos estudantes conseguiram destacar os erros na análise da produção escrita de colegas e que alguns reconhecem que numa função todo elemento do domínio deve corresponder a um elemento do contradomínio, e apenas um. Além disso, os dados sinalizam que esses discentes apresentam dificuldades no uso correto da linguagem matemática.

Published: April 2019

Neste artigo são apresentadas algumas considerações acerca dos materiais de ensino dos saberes elementares matemáticos no curso primário sergipano, durante o período de 1911 a 1931, segundo os princípios da pedagogia em voga, isto é, buscou-se compreender se, em meio ao processo modernizador republicano que vinha se instaurando em todo o país, foram suscitadas alterações no modo como o ensino primário vinha se instaurando no Estado, a fim de desvendar a funcionalidade de propostas e práticas modernas apontadas na legislação. Para alcançar o propósito da investigação foram examinadas fontes de pesquisa como: Regulamentos, Leis, Decretos e Programas de Ensino, que puderam subsidiar a investigação. Como fundamentação teórica, foram adotados autores como Calkins (1886/1950) e Valdemarin (2006), para entendimento do método de ensino intuitivo ou lições de coisas; Souza (2006), Azevedo (2009) e Nascimento (2012), para informações sobre os Grupos Escolares, destaque os sergipanos; e Pais (2011), Pinheiro (2013) e Valente (2008), para pincelar informações sobre os materiais. Com base na investigação realizada constatou-se em Sergipe, referencias a pedagogia nova, baseada pelo método de ensino intuitivo, tendo por princípios o ensino pelos sentidos, pela realidade e pela intuição como principal instrumento de aprendizagem, e os materiais de ensino são considerados como elemento crucial da instrução na legislação, seja para acurar a observação ou para atingir o raciocínio pelo tato e manipulação.
