Pateo do Collegio, lugar de nascimento e memória: a reforma litúrgica realizada por Cláudio Pastro
Authors: Souto Hilda , Fernandes Márcio Luiz
Published: November 2021

RESUMO A origem da cidade de São Paulo está intimamente ligada à fundação do Colégio de São Paulo de Piratininga, em 1554, pela Companhia de Jesus. Em 25 de janeiro desse mesmo ano, aconteceu a missa inaugural celebrada pelos padres Manuel de Paiva e Afonso Brás, com a presença do irmão José de Anchieta, entre outros. Do ano de sua fundação, pela Companhia de Jesus, até hoje, muitas foram as modificações sofridas no complexo arquitetônico original. Inúmeras situações desfavoráveis, tanto políticas quanto religiosas, poderiam ter relegado ao esquecimento uma origem tão singular e tão importante não só no âmbito espiritual, mas também educacional de São Paulo, porém esse lugar permanece como um marco da história da Companhia de Jesus e do seu legado arquitetônico e artístico à cidade. O presente artigo pretende expor alguns dados primordiais da história do Pateo do Collegio para contextualizar as mudanças do projeto iconográfico interno ocorridas no ano de 2009, elaborado pelo artista sacro, Cláudio Pastro (1948-2016), que, a pedido dos superiores da instituição, empreendeu a reforma do espaço litúrgico com base nos documentos da Igreja Católica à luz do Concílio Ecumênico Vaticano II.
O difícil encontro da justiça com a educação: problematizações sobre a justiça restaurativa
Authors: Schilling Flávia , Kowalewski Daniele
Published: November 2021

Resumo Na pesquisa2 que dá origem a este artigo, ao lado do estudo das formas do saber sobre a relação densa e tensa entre justiça e educação, exploramos a vertente das matrizes normativas expressas em políticas públicas que propõem a introdução da justiça restaurativa nas escolas de São Paulo. Neste artigo, trabalharemos esta vertente a partir da análise de dois documentos formativos sobre práticas de justiça restaurativa, explorando visões de conflito, violência, mediação, casos a serem atendidos e expectativas de transformação do cotidiano escolar. Foram feitas oito entrevistas com professores/as de duas escolas municipais que estavam recebendo o projeto e passaram pela formação analisada. Em seus depoimentos, destaca-se a raridade de casos de violência relatados e como a justiça restaurativa é mais compreendida como mediação de conflitos e uma forma de se trabalhar com a disciplina nas escolas. Todas as entrevistas citam o respeito como principal meta dessa forma de justiça, definida como esperança de melhora no convívio. A intenção foi a de verificar os contornos da política na visão dos seus sujeitos e o quanto a formalização da microjustiça – na forma de justiça restaurativa – potencializa (ou não) a possibilidade de se pensar em uma escola justa.

Published: November 2021

Abstract This study analyses, by means of lifespan cost and lifespan assessment, the production of binary concrete admixtures compound by artificial pozzolan and concrete demolition waste. Ten formulations were developed, differentiating them in terms of mixtures, binder and aggregate content, in order to verify their potential use in concrete columns. The replacements were 25% of Portland cement for fly ash and rice husk ash, 15% and 30% of natural coarse aggregates for concrete demolition waste. The results revealed that the mixtures with pozzolan and demolition waste showed higher resistance to chloride penetration. The lowest concrete cost was achieved in the highest compressive strength (35 MPa) and the concrete admixture containing 15% replacement of the natural coarse aggregate by the recycled concrete aggregate and 25% substitution of cement by rice husk ash can be classified as the most environmentally sustainable one, especially in carbon dioxide emissions, among the mixtures studied.

Published: November 2021

Resumo A partir de novas tecnologias como a adição de microfibras de celulose nas argamassas, pode-se obter uma melhoria do desempenho de revestimentos no estado plástico, principalmente porque as microfibras apresentam características hidrofílicas. Contudo, as características físicas e químicas dessas adições, bem como a concentração empregada nas misturas, devem ser controladas para manter um comportamento adequado para as argamassas. O presente trabalho objetivou avaliar a influência da inserção de microfibras de celulose no teor de ar, na retenção de água e na reologia de argamassas. Foram empregados três tipos de microfibras em três teores. Os resultados mostraram que as adições alteraram as características dos materiais e, por isso, há um limite de inserção de microfibra e que é importante analisar as características da microfibra, a fim de atender o desempenho ideal para cada aplicação de argamassa.

Published: November 2021

Abstract Mahogany (Swietenia macrophylla King) is one of the most valuable wood species found in the American Continent. This study is an evaluation of the production of particleboards using wood residues from the branches and trunk of a mahogany tree. It was designed to test the feasibility of production and the mechanical and physical characteristics of the finished particleboards, as well as to compare the results with similar studies and the requirements of normative documents. The particles were generated from the trunk and branches of a mahogany tree separately and mixed in different proportions to test their influence on the final product. They were bonded using 12% polyurethane resin from renewable resources and pressed under 90º C and 3.5 MPa for 10 minutes. The specimens were prepared and tested according to the guidelines established by the NBR 14810 regarding the static bending, internal bond, stiffness and thickness swelling (24h) tests. The results indicated that there is no significant correlation between the trunk-branches proportion and the Modulus of Elasticity/Rupture values. The production of the particleboards using the residues is feasible and the results of most of the tests fitted the normative requirements, which means that with the refinement of the production process it is possible to have a good product that fully complies with the technical standards.

Published: November 2021

Abstract The objective of this paper is to present the formulation of the optimization problem and its application to the design of concrete-filled composite columns with and without reinforcement steel bars, according to recommendations from NBR 8800:2008, NBR 16239:2013 and EN 1994-1-1:2004. A comparative analysis between the aforementioned standards is performed for various geometries considering cost, efficiency and materials in order to verify which parameters influence the solution of the composite column that satisfies the proposed problems. The solution of the optimization problem is obtained by using the genetic algorithm method featured in MATLAB’s guide toolbox. For the examples analyzed, results show that concretes with compressive strength greater than 50MPa directly influence the solution of the problem regarding cost and resistance to normal forces.

Abstract Aim This study aimed to evaluate land use, distribution of particle size fractions, organic matter (OM) and perform a metal quantification liable to complexation in the Itupararanga Reservoir (São Paulo, Brazil). This aquatic ecosystem is used for water supply and energy generation and is constantly subjected to anthropogenic impacts that alter its physical and chemical characteristics. Methods In a single campaign, samples of surface sediment (10 cm) were collected from nine sampling stations, in triplicate, along the reservoir. The collection was carried out with a “Lenz” type bottom sampler. The physicochemical variables, including the quantification of the metals copper, chromium, manganese, nickel, lead and zinc, were evaluated by basic descriptive statistics techniques combined with geostatistics and the use of remote sensing. Results All along the reservoir the sediment is predominantly organic and water depth interfered directly in the OM concentration and particle size distribution. Therefore, heterogeneity was observed regarding OM contents, particle size fractions and metals, with the exception of chromium, and the three zones of the reservoir proved to be distinct from each other. The land use classification showed the real situation of the Environmental Protection Area (EPA) and the results indicate that the central portion is more subject to anthropic impacts, while the dam region has high levels of metals, probably originated from the activities in the reservoir’s surroundings. Conclusions The soil erosion in the reservoir’s region shows the lack of efficiency in the Itupararanga EPA’s management, being needed a strategic coordination among the municipalities to enhance its conservation.

Authors: İpekçi Ahmet , Ekici Bülent
Published: November 2021

The further development of composite manufacturing methods is characterized by the progress of their mechanical properties which are widely used in many applications as automotive, aerospace, and marine industries. The automated composite production techniques are as follows: automatic tape layering, automatic fiber placement, and filament winding methods used in many industries. Photopolymerized composites and their additive manufacturing methods are promising with new advances in technology. This method for printing continuous fiber-reinforced plastic composite parts by a six-axis industrial robotic arm is based on fused deposition modeling technology. The objective of this work is to obtain a better understanding of the mechanical properties of robotic three-dimensional printed photopolymer resin continuous fiberglass–reinforced composites (CFGRCs) as a function of different printing speeds (10, 20 and 30 mm/s), fiber densities (45, 55 and 65%), and fiber orientations (0, 0/90 and ±45°). This work infers that mechanical properties are significantly affected by the fiber density and fiber orientation of CFGRC. With this method, approximately 300 MPa tensile strength can be obtained and structurally preferred instead of ferrous materials in many areas.

Determination of the Effects of Copper (Cu) and Lead (Pb) Heavy Metals on Soil Carbon and Nitrogen Mineralization
Authors: Kizildağ Nacide
Published: November 2021

Heavy metal (HM) pollution has become one of the most important environmental problems of the present day, as a result of the developing industrial activities. Accordingly, it is important to understand microorganism activities in soil ecosystems that have been exposed to HMs for a long time. The aim of this study was to show the potential effects of ores on soil carbon and nitrogen mineralizations which were taken from copper (Cu) and lead (Pb) mines in Balıkesir-Balya and Kastamonu-Küre districts in Turkey. The carbon (C) and nitrogen (N) mineralizations were determined by using the CO2 respiration method (30 days) and the Parnas Wagner method (42 days) under the controlled laboratory conditions (28 °C, 80% of field capacity), respectively. It was observed that carbon mineralization decreased depending on the dose increase. 250 mg kg-1 treatment with Pb was lower than the control and there was a significant difference between them (P < 0.001). In terms of nitrogen mineralization rate (%), there was no significant difference among all treatments. According to the results, Pb affected microorganisms more negatively; however, the presence of Cu slightly decreased its negative effect. It is possible to conclude that carbon mineralization can be indicator for HM pollution in the soil. However, nitrogen mineralization was not a determining factor at HM pollution in this study.

A single specimen of a bull shark Carcharhinus leucas (Müller & Henle 1839) with c. 102 cm of total length was landed and photographed on 25 March 2019 in Sungai Mawai Lama, about 25 km inland, Kota Tinggi District, Johor, Peninsular Malaysia. This rare finding represents only the second record of C. leucas in inland Peninsular Malaysia. This shark was identified as C. leucas by the snout much shorter than the width of mouth and bluntly rounded, first dorsal fin triangular, rearward sloping, originating over or slightly behind pectoral insertion, second dorsal fin much smaller than the first dorsal fin (< 3.1:1), and lack of an interdorsal ridge. The coloration of fresh specimen: greyish back and white belly, the dark coloration on the tip of the caudal fins and second dorsal fin. This species is currently listed as a vulnerable species based on the IUCN Red List Status. Further study and monitoring are needed to assess the possibility of the importance of Sungai Mawai Lama as critical habitat of C. leucas.

Problem of the Effectiveness of Parental Assistance to Children in Situations of Educational Difficulties From the Perspectives of the Reflection-Activity Approach and Cognitive-Behavioral Therapy
Authors: Zaretsky V.K. , Ageeva A.A.
Published: November 2021

The article considers the subject of effectiveness of parental assistance to children in challenging situations from the practical and theoretical perspectives. The conditions and criteria of psychological assistance effectiveness represent a link between these perspectives. Proceeding from the fact that development is the child’s main life context, the subject of assistance effectiveness is viewed through the lens of its relation to development. The authors word and provide the rationale for an assumption that effective assistance implies facilitation of development. Due to a conceptual closeness of cultural-historical psychology (as a developmental theory) and cognitive-behavioral psychotherapy (CBT) as a practice of promoting cognitive development, the criteria for the effectiveness of assistance contributing to the child’s development are singled out and compared. A taxonomy of modes in which parents provide assistance to their children in challenging situations in terms of their effectiveness is viewed from the perspective of the reflection-activity approach (RAA) and CBT. The article presents the results of an empirical study of the parental assistance modes in the context of helping their children overcome learning difficulties in a sample of 100 parents of primary school students. The study relied on unique methodology. The results showed that, according to the effectiveness criteria developed, the overwhelming majority of the parents (94.5%) presented with assistance modes that did not contribute to the children’s development, i.e. these modes were ineffective. The issue of specific culture of rendering assistance with learning difficulties is discussed and it is inferred that there is a need to engage parents in practical psychological work to restructure their assistance modes by means of RAA and CBT.

Karadeniz’in uluslararası ticarete açılması ile birlikte Karadeniz’de seyrüsefer yapan gemiler, Güney Karadeniz sahilinde yer alan şehirlerin önemini arttırmıştır. Bu kentlerden birisi olan ve çok eski zamanlardan itibaren korunaklı yapıdaki limanıyla önemli bir yer olan Sinop da bu artan ticari faaliyetlerden faydalanmış, ecnebi devletlerin yoğun ilgilerine mazhar olmuştur. Bu devletlerden birisi olan Rusya, Küçük Kaynarca Antlaşması’nın ardından Sinop’a bir konsolos atayarak I. Dünya Savaşı yıllarına kadar buradaki varlığını sürdürmüştür. Şehirdeki Rus konsolosları, buradaki faaliyetleri çerçevesinde kimi zaman Osmanlı idarecileri ile iyi ilişkiler kurmuş, kimi zaman da devletin iç işlerine müdahale etmekten çekinmemişlerdir. Şehirde yaşayan Osmanlı tebaası Rumlar üzerinde de hakimiyet kurmaya çalışan Ruslar, uzun yıllar boyunca Sinop’ta varlık göstermişlerdir. Bu çalışma, XIX. yüzyıl boyunca Rusların Sinop’taki varlık nedenlerini ve faaliyetlerini incelemeyi amaçlamaktadır.
Osteological studies of skull base neurovascular area in reference to infratemporal approach to skull basec
Authors: Sharma Harsh
Published: November 2021

Surgical approaches to the lateral skull base often lead to tearing of vessels and piecemeal removal of the tumour. This study is aimed to delineate exact relationship of the various foramina at the lateral skull base. The coronal dimensions of the jugular foramina are larger as compared to sagittal with right sided dominance also noticed in the case of carotid canal. The width of “Keel” separating the carotid and jugular foramina normally varies from 0.4 to1.4 centimetres and may not always suggest the erosion of the foramen of skull base scans, unless the erosion is associated with irregularity or demineralization the thickness of this keel really depends upon relative size of the vessels and location of foramina. Area between stylomastoid foramen, carotid canal and jugular foramen is roughly wedge shaped. The angle subtended by carotid and jugular at the stylomastoid foramen is about 36.84whereas the location of stylomastoid foramen and internal carotid axis pose an angle of 83:16. The angle subtended by stylomastoid and jugular at carotid on an average 59:31. The space between these structures is measured to be 0.642centimetres which can be verified on tomograms.

By using these measurements, the precise location of the upper end of the vessels could be predicted, whereas the superior stump could be clamped with minimal exposure of the skull base and identification and location of the last four cranial nerves is found out. This could avoid injuries and subsequent morbidity while carrying out surgery in this region.

Published: November 2021

Tubercular retropharyngeal abscess along with potts spine is very rare in children. As there is no specific sign and symptoms of tuberculosis are present and even if present can be masked by features of nretropharyngeal abscess these cases may have delay in diagnosis. Early diagnosis is important to start proper treatment and can prevent the disability and mortality. In this article we report a case where a child presented to our opd with complaint of right sided neck swelling, dysphagia and neck pain with restricted movement. Any symptoms or signs of tuberculosis were not present. Clinical examination and MRI of neck suggested this as a case of retropharyngeal abscess with cervical spine involvement. Intraoral surgical drainage of pus sent for CBNAAT examination and it revealed the diagnosis of tuberculosis. Antitubercular regimen was given for 12 months. During follow up his symptoms gradually improved and after 1 and 2 year follow up child was free from tuberculosis. So in conclusion we can say retropharyngeal abscess in child should be dealt promptly and in case of abcesses refractory to conventional medical treatment, high degree of suspicion of tuberculosis should have present especially in endemic countries in order to reduce morbidities and improve clinical outcome. Early diagnosis and treatment can improve the scenario significantly.

Published: November 2021

Introduction: One of the most challenging decisions is to assess the preterm infant’s transition from tube feeding to oral feeding. Thus, we require a reliable tool for determining the time to start oral feeding. This study aimed to measure the interrater and intrarater reliability of the Preterm Infant Oral Feeding Readiness Assessment scale (PIOFRA).
Materials and Methods: This study was an observational, cross-sectional study. The study participants were preterm infants who had been hospitalized in the Neonatal Intensive Care Unit of Shariati Hospital affiliated to Tehran University of Medical Sciences, between December 2017 and February 2018. The inclusion  criteria  were  absence  of neurological and gastrointestinal disorders or major congenital anomalies, Apgar score 3 or more in the first 1 minute, and 5 or more in the first 5 minutes. The exclusion criteria included family’s unwillingness to participate in the study, infant’s death, or a sudden change that affects neonates’ nutritional status, like cerebral hemorrhage or intestinal problems.
Results: The interrater and intrarater reliability of the total PIOFRA scale was good Intraclass Correlation Coefficients (ICC˃0.75). The interrater and intrarater reliability of most items were good and excellent, with weighted kappa more than 0.50, with the exception of lip posture and especially stress sign, with weighted kappa less than 0.40.
Conclusion: Generally, most items of the PIOFRA scale had acceptable interrater and intrarater reliability. Also, the interrater and intrarater reliabilities of the total POFRAs score was good.

Introduction: Position sense, one of the most accurate senses in the body, makes everyone aware of the state of the body in space. This sense is an essential ability in maintaining physical health and avoiding injury. Deficits in position sense cause balance impairments in people with mild Multiple Sclerosis (MS). Position sense requires instant and coordinated communication between the central nervous system and peripheral nervous system, while in patients with MS, communication between the brain and other parts of the body is disrupted. This study aims to compare the position sense of knee joint in people with MS and healthy subjects.
Materials and Methods: Ten healthy subjects with the Mean±SD age of 27.6±3.71 years and 10 persons with MS disease and the Mean±SD age of 31.40±3.50 years participated in this study. For evaluating their position sense of knee joint, they flexed their knees (from 90 to 45 degrees) four times, and then a software calculated their repositioning errors.
Results: No significant changes in repositioning errors (constant, variable, absolute) were observed in MS patients, and the control group (P˃0.05).
Conclusion: The results indicate that mild MS disease cannot disturb the position sense of knee joint.
Redes sociales: el carnaval, el mito y el héroe

Published: November 2021

En el presente documento intentaremos no recurrir a determinismos, ya sean apocalípticos o integrados (Eco, 2004), sino que apelaremos a generar nuevas lecturas y preguntas desde una perspectiva crítica. De esta forma, nos proponemos abordar -en torno a las redes sociales- algunas concepciones teóricas sobre la figura del carnaval y la máscara, como también, desarrollar articulaciones en torno a la noción de exposición y del mito del héroe para repensar la participación ciudadana en la red. Transversalmente, se intentarán evidenciar las posibles tensiones en relación a la mercantilización de la cotidianeidad, a través de la instauración de necesidades, el consumo incesante y la manipulación subjetiva que subyace en ciertas estrategias del mercado vía redes sociales, intensificadas más aún en épocas de COVID-19. La máscara y los personajes que encarnan se materializan como analizadores que permiten visualizar aquello que podría estar detrás, lo oculto, y asimismo, posibilitan distinguir entre –lo que aquí denominamos- las identidades inventadas (usuarios) y las identidades construidas históricamente, aquellas que nos nombran y nos dan pertenencia en una genealogía (el nombre propio). En el complejo ordenamiento social y simbólico que producen las redes, entendemos que existen expresiones de múltiples violencias: de género, ambiental, económica, psicológica, violencias sobre los derechos de grupos, sobre los valores colectivos. Es decir, bajo la lógica de la reproducción social de las desigualdades, para que haya héroes debe haber caídos.
La política migratoria de Trump y el acuerdo México-Estados Unidos: ¿Suficientes para el resguardo de la dignidad migratoria?
Authors: Salazar Urbina Daniel Stefano
Published: November 2021

Desde épocas anteriores, México y Estados Unidos se sumergieron en un enfrentamiento que comprendió una variedad de causas. Ejemplos de esta afirmación lo constituyen políticas comerciales, de seguridad, migratorias, entre otras. Precisamente, uno de los aspectos que acentuó las rencillas entre los países mencionados, durante los últimos años, ha sido la disyuntiva relativa a los intentos de uniformizar las reglas para establecer un procedimiento migratorio seguro, transparente, no diferenciador y garante de los derechos humanos inherentes a todo migrante centroamericano. Al margen de que se suscribió un acuerdo migratorio entre México y Estados Unidos (la Declaración Conjunta) con el propósito de coadyuvar a aliviar el dilema anterior, no debe olvidarse que tal instrumento fue la respuesta a una rígida política migratoria dirigida por Donald Trump que afectó gravemente lo que se conoce como la dignidad migratoria de los individuos centroamericanos (propiedad humana que desprende el respeto e igual consideración que debe propenderse en favor de los migrantes para con el resto de la sociedad). De esta forma, el objetivo del presente trabajo es determinar la forma en que la irrestricta política migratoria norteamericana degradó la dignidad migratoria, a fin de comprobar si la estructuración de la Declaración Conjunta entre México y Estados Unidos constituyó una herramienta suficiente e idónea para aliviar los problemas que afectaban el tránsito migratorio centroamericano y, sobretodo, la dignidad migratoria.
Indigenising positive psychology in the ‘Handbook of Quality of Life in African Societies’
Authors: Nel Jan Alewyn
Published: November 2021

This book review highlights the main themes of the Handbook of Quality of Life in African Societies (as edited by Prof Irma Eloff from the University of Pretoria), focusing on meaning and language, culture (and positive culture), and social responsibility. The interrelatedness of all five parts of the book (from a macro, meso and micro perspective) are discussed with specific mention of Ubuntu and its relevance in investigating the phenomenon of quality-of-life. The review emphasises the need for exploratory and indigenous research in communities where social association is of immense importance and to contextualise quality-of-life from this perspective. This book is recommended for scholars who wishes to utilise indigenous methodologies and to deeper understand the diverse influences and social impact on the quality-of-life of individuals south of the Sub-Saharan Africa.
Lógica relacional del Estado: Revisitando el aporte teórico de Nicos Poulantzas en Estado, Poder y Socialismo
Authors: Fernández Javier
Published: November 2021

Durante mucho tiempo, el estudio del Estado ha estado signado por una comprensión monolítica, toda vez que se ha entendido o como la única posibilidad para evitar la batalla de todos contra todos, la expresión suprema de la sociedad o un acuerdo de una clase para la mera opresión de otra. Bajo esta premisa, es que Nicos Poulantzas desarrollará una propuesta crítica en la concepción y abordaje de la arquitectura estatal, comprendiéndola como un espacio de constante disputa y cristalización del conflicto de clases, apuntando a entenderlo como a un todo complejo que nunca logra pertenecer por entero a un sector. Dichas observaciones revisten una importancia trascendental, dado que con ello, quienes aspiren a comprender la institucionalidad desde las Ciencias Sociales encontrarán una propuesta compleja para el estudio del Estado. En esta lógica es que el presente trabajo pretende ser una revisión de Estado, Poder y Socialismo de Poulantzas, considerando que este texto guarda un aporte teórico fundamental para el estudio politológico. Abocándonos a revisar algunos planteamientos, apuntamos a aportar algunas orientaciones conceptuales del autor greco-francés a fin de que puedan servir para profundizar en un proyecto teórico de suma relevancia en los tiempos que la desafección política y las luchas por el Estado están más presentes que nunca.
