Published: December 2021

El trabajo se enmarcó en el pensamiento valorativo del líder educativo cuyo propósito general generar un corpus teórico del líder educativo y el pensamento axiológico. Caso Escuela Municipal de Talca, Chile. Se enmarcó en el paradigma cualitativo interpretativo; teniendo un apoyo en la hermenéutica. Se empleó cinco (05) informantes clave: dos (02) directivos y tres (03) docentes. Las técnicas de recolección de la información fueron: la entrevista en profundidad y la observación participante, se interactuó con los informantes clave mediante la conversación informal y espontánea; dentro que las de interpretación se utilizaron: la categorización, triangulación y la teorización. Se concluyó en que los líderes educativos carecen de la orientación en función de las demandas, exigencias, necesidades e intereses del colectivo, que no conducen al comportamiento con actitudes grupales. Además, se requiere sentido de pertinencia en comprensión para llegar a afianzar la pertenencía social, siendo abiertos a todo cambio con el propósito de alcanzar la flexibilidad integral.

Published: December 2021

A Base Nacional Comum Curricular, homologada em 2017, é o mais atual documento do âmbito educacional brasileiro que normatiza as práticas pedagógicas nas instituições de ensino. Na etapa da educação infantil, o brincar é definido com um dos direitos de aprendizagem e desenvolvimento, logo uma demanda dos gestores escolares é a sua garantia no cotidiano infantil. A brinquedoteca é um espaço planejado para as crianças que proporciona as brincadeiras, interações e desenvolvimento. Nesse contexto, o objetivo geral do trabalho foi realizar uma proposta e orçamentos de recursos lúdicos para uma brinquedoteca em uma escola municipal de Gramado, no estado de Rio Grande do Sul, consoante as descrições da Base Curricular e Referencial Curricular Gaúcho. A metodologia utilizada foi de abordagem mista, englobando os aspectos qualitativos e quantitativos diante de análise documental e estimativas de custo. Como resultado foi constatado que um projeto de brinquedoteca com diversos materiais, elementos naturais e da cultura local é uma possibilidade, considerando os recursos financeiros e a realidade escolar.

Authors: Barros Marta Silene Ferreira , Garcia Natália Navarro , Leite Sandra Regina Mantovani , Arruda Viviane Aparecida Bernardes de
Published: December 2021

Considerando a relevância da perspectiva crítico-dialética nos estudos relacionados à formação e ao desenvolvimento emocional da criança, objetiva-se apresentar considerações e provocações sobre o desenvolvimento dos aspectos afetivo-emocional na criança nos seus primeiros anos de vida a fim de que haja um maior entendimento dessas funções para qualificação do trabalho educativo. Para tanto, procede-se à pesquisa bibliográfica e às discussões oriundas do grupo de pesquisa FOCO - (Formação, Práxis e emancipação na Educação Escolar: Implicações da Teoria Histórico-Cultural no Ensino, Aprendizagem e no Desenvolvimento Humano), vinculado ao CNPq e à Universidade Estadual de Londrina. Observa-se que a teoria que subsidia a discussão vai ao encontro dos pressupostos das teorias psicológicas tradicionais permitindo concluir que o desenvolvimento infantil proposto nesse estudo é compreendido na relação dialética, histórica e sistêmica entre a afetividade, a cognição, o biológico e o cultural.
Práticas educativas e ressignificações dos saberes e fazeres das Bandas Cabaçais rurais: ações decoloniais no contexto musical urbano/contemporâneo
Authors: Braga Elinaldo Menezes , Lucini Marizete
Published: December 2021

As Bandas Cabaçais, também chamadas de Bandas de Pífanos, são grupos musicais de tradição rural existentes no Nordeste brasileiro desde o período colonial. Hegemonicamente constituídas por homens e vinculadas ao catolicismo popular, não dispensam oportunidades para profanar e libertar a brasilidade das masmorras capitalistas que negam a pluralidade, silenciam saberes, não reconhecem práticas educativas outras e condenam ao esquecimento tudo o que rompe com os padrões impostos pelo projeto de modernidade colonialista. Na contemporaneidade, contudo, esses grupos têm recebido olhares por parte de músicos urbanos, pesquisadores e produtores culturais, cujos trabalhos têm contribuído para o surgimento de projetos que ressignificam o fazeres populares tendo as Bandas Cabaçais como fontes de saberes e modos outros de existirem. Neste trabalho de cunho qualitativo, destacamos experiências de algumas musicistas para compreendermos por quais práticas educativas elas e outros/as novos/as pifeiros/as urbanos aprendem, transmitem, aprendem e ressignificam a cultura cabaçal. A coleta dos dados se deu através de entrevistas pelo whatsapp. Esperamos que os exemplos em tela inspirem e despertem o interesse de muitos outros(as) musicistas pela arte cabaçal.
Afirmações dos estudantes sobre gênero: um estudo comparativo na Universidade Federal de Sergipe e na Universidade da Madeira
Authors: Brazão José Paulo Gomes , Dias Alfrancio Ferreira
Published: December 2021

Este artigo apresenta uma análise da categoria de gênero, no decurso de um estudo comparativo na Universidade da Madeira, UMa (Portugal), e na Universidade Federal de Sergipe, UFS (Brasil), sobre “Vozes dos estudantes universitários sobre a diversidade sexual e de gênero, sua relação com a coeducação e com a inovação pedagógica.” Em termos metodológicos foi adotada uma abordagem qualitativa, com aplicação de um questionário com questões abertas e fechadas e o visionamento de um vídeo curto de enquadramento do tema. Foi feita a análise de conteúdo aos dados obtidos. Os resultados comparados mostram semelhança nos dois contextos estudados, relativamente ao conhecimento do conceito gênero. Porém, divergem relativamente ao envolvimento em conversas e debates sobre o tema no meio acadêmico. São os ex-estudantes da UFS os mais participativos e os ex-estudantes da UMa os que afirmam nunca ter participado. Os ex-estudantes dos dois contextos referem também que o tema gênero é tabu e que existe ainda preconceito social na sua discussão. Os ex-estudantes das duas universidades estudadas consideram que a abordagem, o envolvimento e a discussão deste tema melhoram o autoconhecimento, a afirmação pessoal em sociedade, sendo por esse motivo um tema educacional a trabalhar na academia.
O que pode um currículo? Breve ensaio sobre o currículo em imanência
Authors: Feldens Dinamara Garcia , Catanhede Camilo , Fusaro Luana
Published: December 2021

Este artigo, escrito a partir de discussões e leituras entre os autores, membros do grupo de pesquisa Educação, Cultura e Subjetividades (GPECS/CNPq/UFS), e desenvolvido através da dissertação de Mestrado de um dos autores, propõe uma reflexão sobre aspectos da teoria de Baruch de Spinoza para compor diferentes modos de educar. Busca-se considerar um currículo que extrapole os modelos tradicionais, e que esteja comprometido em produzir uma educação potencializada por afetos alegres. Neste sentido perguntamos: o que pode um currículo? Para pensar sobre esta questão, iremos utilizar os resultados sistematizados de uma pesquisa de experimentações curriculares, realizada durante quase três anos, em uma escola localizada no estado de Sergipe. Além Spinoza, traremos no referencial teórico conceitos de Gilles Deleuze e Félix Guattari e a ideia de nomadismo curricular de Sandra Mara Corazza. Com essa articulação, buscamos demonstrar alguns princípios e práticas que convergem à uma educação amorosa, composta por afetos alegres, capaz de aumentar a potência e a intensidade do pensamento e da aprendizagem.
Indazole Derivatives Effective against Gastrointestinal Diseases
Authors: Saha Supriyo , Pal Dilipkumar , Nimse Satish Balasaheb
Published: December 2021

Background:

In this fast-growing lifestyle, humans are in the race against time to cope up with busy schedule. Less exercise, consumption of high calorie-low fiber food and stress take us one step closer towards digestive dysfunction. Dysfunctional digestive system causes various gas-trointestinal disorders like constipation, IBS, UC, diarrhea, gastrointestinal tract immobility, hyper-glycemia, hemorrhoids, fistula, anal fissures, stomach cancer, hepatocellular carcinoma, pancreatic cancer, colon cancer and metabolic syndrome. Amongst various natural and synthetic indazole de-rivatives nigellicine, nigellamine, nigellidine, zanubrutinib and SCH772984 showed prominent re-sults to cure various gastrointestinal disorders.

Objective:

In this manuscript, we focus on the importance of indazole derivatives in the treatment of various gastrointestinal diseases.

Results and Conclusion:

In the treatment of IBS, four positions (R1, R2, R3 and R4) of indazole were mainly substituted with aromatic aldehyde/substituted methyl, aromatic acid/formamide, ben-zamide/sulfonamide and methyl groups, respectively. In case of diarrhea and metabolic syndrome treatment, substitutions with benzyl/isopropyl/acetaldehyde (R1 position) and carboxamide/ formamide (R2 position) of indazole play a critical role. Also, in the treatment of diabetes melitus, all six positions of indazole derivative were substituted with substituted aryl/alkyl/aromatic acid, substituted formamide, substituted acetamide/hydrazide group, halo aryl, substituted aryl/aromatic acid and a long chain of alkyl-aryl alcohol groups, respectively. In the treatment of gastrointestinal cancers, all six positions of indazole derivative were substituted with benzylamide (R1), octanedia-mide/benzamide/formamide (R2), carbaldehyde (R4) and substituted phenyl (R5 and R6) groups, re-spectively. Six receptors (6NP0, 2YME, 4EFU, 4WZ8, 5U4W and 7KKP) associated with GI dis-orders (co-crystallized with indazole derivative) were identified. Analysis of the receptors showed that co-crystalized ligand molecules were well-interacted with receptors via pie-pie interaction, co-ordinate and sigma bonding within 4 Å distance. As per Ramachandran plot analysis, more than 90% of the amino acid residues were present in the most favored region. So, if sufficient focuses are imposed on the development of newer indazole derivatives to treat gastrointestinal diseases, it will work as a boon to society.
Impact of racial differences on the epidemiology and clinical outcomes of atrial fibrillation
Authors: Quah Jing Xian , Dharmaprani Dhani , Tiver Kathryn , McGavigan Andrew D. , Ganesan Anand N.
Published: December 2021

:

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased morbidity and mortality. The overall AF burden is expected to rise over the next decade, and this will have significant implications on the healthcare cost. Current literature on the pathophysiology, epidemiology and management of patients with AF have focused mainly on predominantly Caucasian/white population while published studies in non-white populations have been mainly observational or retrospective in nature. Hence, the implications of AF in terms of management and complications in the non-white population have not been fully appreciated. In this review, we summarized based on the available literature, the racial differences in the prevalence, management and outcomes of patients with AF comparing the white vs non-white population.
Solitary Fibrous Tumors Arising from Bilateral Ovaries: A Case Report
and Review of the Literature
Authors: Tian Tongtong , Ye Jing , Sun Jun
Published: December 2021

Background:

A solitary fibrous tumor (SFT) is a distinct mesenchymal neoplasm. It
was originally described as a tumor localized to the pleura but was later reported in several other
anatomic sites and exhibited a wide spectrum of histological features. Owing to its rarity, the diagnosis
of extrapleural SFT is challenging and requires an integrated approach comprising specific
clinical, imaging, histological, and immunohistochemical findings.

Case Presentation:

Herein, we report the imaging findings of a rare case of SFT arising from bilateral
ovaries confirmed by surgical excision and histological examination. No adjuvant radiotherapy
or chemotherapy was given to the patient, and she was disease-free with no evidence of recurrence
or metastasis at the 96-month postoperative follow-up. Although it mostly follows a favorable
course, SFT is notoriously difficult for prognostication because of its propensity for late relapse or
even metastases in 10-39% of cases.

Conclusion:

Close follow-up is recommended because of the limited information on its long-term
behavior.

Arquitectura y Urbanismo del Cusco Inka
Authors: Mar Ricardo , Matos Ramiro , Beltrán Caballero José Alejandro
Published: December 2021

Cusco, la ciudad más importante del Tawantinsuyu, fue morada de la nobleza y sede del poder político y religioso. El alto nivel de su arquitectura y urbanismo ha impresionado tanto a los primeros europeos del siglo XVI, como a los académicos y turistas que hoy visitan la ciudad. Los primeros la compararon con otras ciudades de España y vieron en el Qhapaq Ñan, la red de caminos que conectaba el sistema de asentamientos andinos, un equivalente de la vasta red de caminos romanos. Afortunadamente para Cusco aún quedan en pie partes significativas de su pasado Inka. Hemos catalogado las antiguas edificaciones, identificado escondidos entre muros o cimientos de construcciones coloniales y modernas, también los que perdieron su contexto y los que aparecen durante los nuevos trabajos en calles y plazas de la ciudad contemporánea. Estos datos combinados con la información que aportan los cronistas de la Colonia, la literatura arqueológica moderna, las fuentes históricas, etnohistóricas y de la antigua capital. Partiendo de la singularidad que representa Cusco en el contexto amerciano, Arquitectura y Urbanismo del Cusco Inka se ocupa principalmente de su geografía, planeamiento y arquitectura, mostrando a través de un amplio repertorio de planos, fotografías y restituciones tridimensionales cómo pudo ser la sede del poder inkaico. El desarollo de nuevas tecnologías digitales aplicadas a la arqueología oferece la posibilidad de avanzar en el estudio de la ciudad histórica de un modo hasta ahora desconocido. La gestión de fotos áreas y satelitales, los sistemas geográficos integrados (GIS), el láser scanner, el uso de los drones o los programas de modelado 3D automatizado, abren nuevas perspectivas en la investigación de campo y en la documentación de los restos arqueológicos, estimulando nuevas aproximaciones a la realidad del urbanismo Inka.

Published: December 2021

El presente artículo tiene como objetivo analizar la importancia del servicio y oferta en los hoteles boutique para mejorar su posicionamiento y rentabilidad en un mercado creciente, en este caso particular en el hotel del Parque en las afueras de la ciudad de Guayaquil. Para este análisis se consideró la encuesta para observar primeramente el posicionamiento del hotel frente a su competencia cantonal y nacional, la misma que fue realizada a un grupo de 300 personas de público general, externo y aleatorio; además se realizó un estudio de campo en el hotel, y se analizaron los comentarios de huéspedes de tres de las principales OTAS (Agencias de viaje virtual) donde los clientes compartieron su percepción sobre el servicio y la oferta recibida. También se analizó la oferta de paquetes y servicios con los que trabaja actualmente el hotel. Los resultados demostraron el grado de posicionamiento del hotel dentro del sector y en el mercado de los hoteles de lujo y boutique desde una perspectiva general, así como la percepción de satisfacción del huésped durante su estadía, donde se adicionaron los puntos claves que hicieron que su experiencia cumpla su ciclo de servicio de manera exitosa. La reflexión final indica que en un hotel boutique el servicio superior y de calidad, así como la capacidad del hotel para adelantarse a las necesidades del huésped y sorprenderlo de manera creativa y elegante, conllevan a la creación de experiencias que serán memorables y únicas, y que contribuirán al crecimiento de la marca y a la rentabilidad.

Влияние анодной и катодной плазмы на работу электронного диода со взрывоэмиссионным катодом
Authors: Пушкарев А.И. , Полисадов С.С.
Published: December 2021

The results of modeling and experimental investigation of the formation of anode and cathode plasmas in a vacuum diode with an explosive-emission cathode during the generation of a pulsed electron beam with a current density of 0.3-0.4 kA/cm^2 and an accelerating voltage of 300-500 kV are presented. It is shown that the concentration of the anode plasma does not exceed 10^10 cm^-3 and it does not significantly contribute to the operation of the diode. However, the complete desorption of molecules from the working surface of the explosive-emission cathode and the high efficiency of shock ionization of atoms ensure the formation of a cathode gas plasma with a concentration of 10^16 cm^-3. It is found that the charge of the explosive-emission plasma layer is significantly less than the charge of the electron beam and the main source of electrons is not an explosive-emission plasma, but a cathode gas plasma. In this case, the electron current is limited by the concentration of the cathode plasma. The use of a cathode with a developed surface (a cathode with a carbon fabric coating) allows increasing the total charge of the electron beam by more than 1.5 times without changing the cathode diameter and the anode-cathode gap.

Composites of heterospin molecular magnet [EuIII(SQ)3bipy] in a polystyrene (PS) matrix have been synthesized. This complex [EuIII(SQ)3bipy] contains four paramagnetic centers - the Eu3+ ion and three SQ ligands (SQ—3,6-di-tert-butyl benzoquinone radical anion); bipy (bipyridyl) is diamagnetic. It has been established that intensive mechanical activation of [EuIII(SQ)3bipy]/PS samples leads to an reological explosion, as a result of which radio frequency superradiance, the appearance of free electrons and the formation of Eu metal nanoparticles are observed. The duration of this process is 10 ns.

Особенности применения теоремы вириала для магнитных систем с квазибессиловыми обмотками
Authors: Шнеерсон Г.А. , Шишигин С.Л.
Published: December 2021

The article shows that in a magnetic system with a thin-walled balanced winding close to a force-free one, a significant increase in the parameter θ=WM γ/M σМ , is possible, which, according to the virial theorem, characterizes the ratio of the energy of the magnetic system WM to the weight of equipment with a material density γ, where under the action of electromagnetic forces there appears a mechanical stress σМ. In a quasi-force-free magnetic system, the main part of the winding is in a state of local equilibrium, and only a relatively small part of the equipment is subject to stress. This part determines the weight of the entire system, and this weight can be minimized. The configurations of balanced thin-walled windings are developed, at the boundaries two boundary conditions are fulfilled simultaneously - the absence of the induction component normal to the boundary and the constancy of the product of induction and radius. The authors consider an example of a system consisting of a main part - a sequence of balanced "transverse" modules in the form of flat discs and end parts, consisting of a combination of "transverse" modules and "longitudinal" ones, having the form of rings elongated along the axis with balanced end parts. It is shown that in the system under consideration, the characteristic dimensionless parameter θ with an unlimited increase in the number of elements of the main part can reach a value of about 24, and when the number of these elements changes within 20 - 40, it changes from 6 to 9.
Вероятность ионизации атомов, распыленных при бомбардировке поверхности металлов одно- и многозарядными ионами
Authors: Белых С.Ф. , Беккерман А.Д.
Published: December 2021

The processes of ionization of atoms sputtered under bombardment of clean metal surface by singly and multiply charged ions with kinetic energy of several keV were studied. Within the framework of simple phenomenological model of ion formation, the relaxation of local electron excitation in metal was taking into account. Analytical expressions for estimation of ionization probability of sputtered atoms was obtain. It was shown, that in comparison with singly charged ions, bombardment of metals with multiply charged ions results to significant increase of ionization probability of sputtered atoms due to more efficient excitation of electrons and increase of relaxation time of this excitation.

Configuration of an experiment was a model of thrombus detection in a blood vessel. Stray magnetic field was varied by movement of a magnetic composite above the element perpendicular to the long side. Composite was either magnetized or not to the state of remanence. As the magnetic composite approaches the GMI element, MI ratio curves are smoothed and shifted along the field axis and maximum value of the MI ratio decreases. Magnetic properties of magnetic composite and film element were investigated as well.

El papel de la nutrición y el factor socioeconómico ante la pandemia
Authors: Hernández Pérez Hugo Antonio , Castellanos Castellanos Sandra Elisa , Vera González Alan Aldair , Romo León Zamara Lizbeth
Published: December 2021

Desde que el covid-19 fue anunciado como pandemia se han buscado distintos tratamientos farmacológicos para combatirla. De manera simultánea se han publicado propuestas que asocian el papel de la nutrición y prevención del covid-19, se incluyen, propuestas de estrategias de suplementación dietaria que tienen por objeto que aquellos pacientes que presentan la enfermedad no cursen a las etapas más severas de la misma. El apoyo nutricio representa entonces una herramienta contra el covid-19. Lo anterior adquiere gran relevancia en aquellos pacientes con diversas comorbilidades asociadas al covid-19 como diabetes, obesidad e hipertensión. De acuerdo con la nom-043-ssa2-2005 la dieta correcta se refiere a la unidad de alimentación, es decir, al conjunto de alimentos y platillos que se consumen de forma diaria y que tiene las siguientes características: completa, equilibrada, inocua, suficiente, variada y adecuada y se logra a través de una buena cultura alimenticia y la factibilidad de acceso a los alimentos que se ve influido por el factor socioeconómico; Latinoamérica cuenta con un alto porcentaje de su población en condiciones de pobreza, tiene las comorbilidades antes mencionadas, y una dieta poco nutritiva, por lo que presentan un mayor riesgo a desarrollar las etapas severas del covid-19. El objetivo en este trabajo es mostrar un panorama sobre la información relacionada con la nutrición que se presenta como un elemento que puede sumarse al tratamiento de pacientes que padecen con el covid-19 y relacionarlo con el factor socioeconómico de la población. Entre las conclusiones obtenidas se indica que un plan de nutrición con enfoque en prevención o soporte nutricio frente al covid-19 es un factor que puede ser adicionado al tratamiento de los pacientes que cursan con la infección por sars-cov-2. Es un hecho que la disparidad observada en el ámbito nutricional depende en gran medida del factor socioeconómico que determina qué tipo de alimentos y con qué frecuencia podrán ser consumidos por los miembros de la familia.

En este contexto se analizan las condiciones de los alumnos que habitan en comunidades rurales y de alta marginación del estado de Tamaulipas, México, entidad con altos índices de violencia, enfatizando la afectación que en términos individuales, colectivos y sociales genera el déficit alimentario de al menos 32,010 menores durante la pandemia.
A Comparative study of SQL Databases and NoSQL Databases for E-Commerce
Authors: Nakhare Disha
Published: December 2021

Abstract: With the advent of E-Commerce, businesses persistently examine various ways to improvise and accomplish their demands with web engineering that provide notable resolution. The progress in economic status demands colossal databases that store the data efficiently. The databases currently used are relational or non-relational. Both these types have their benefits and limitations that influence the overall processing of data. Non-relational databases are referred to as NoSQL-not only SQL, and Relational databases are known as SQL-Structured Query Language. It has been suggested in many studies that NoSQL databases surpass SQL databases. Our paper aims to evaluate these claims by analyzing the CRUD [Create, Read, Update, Delete] operations executed by both database types. Keywords: NoSQL, SQL, Non-relational Databases, MySQL, E-Commerce, MongoDb , Relational Databases
Tensiones de la Gobernanza comunitaria de servicios sanitarios rurales en territorios periurbanos (Chile)
Authors: Duarte-Vera Alejandra Ester , Vanhulst Julien , Letelier-Araya Eduardo Antonio
Published: December 2021

Unlike the private concession model applied in urban zones, rural water sanitation services in Chile are managed by rural drinking water (RDW) committees or cooperatives, under a community governance model. This article seeks to understand the tensions and conflicts faced by RDW community governance in the peri-urban territories of regional capitals, which are at the frontier of the private drinking water management model. Based on a political ecology and hybrid governance approach, this research proposes the hypothesis that, on facing urban expansion and water scarcity, the neoliberal institutional framework tends to favour drinking water market governance in peri-urban territories. With this aim, and through semi-structured interviews and participatory observation, focusing on three RDW cases located in the peri-urban zone of Talca, this study develops a critical discourse analysis of community managers and government regulators, identifying their perceptions and positions on current socio-ecological transformations, and community governance tensions. Consistent with the proposed hypothesis, from discourse analysis, it is possible to infer the potential risks of privatization, derived from the implementation of Law No. 20,998, which regulates rural water sanitation services.
ARQUITECTURA PARA LA COMUNIDAD EN AMÉRICA LATINA

Published: December 2021

Arquitecturas del Sur magazine, in its 60th issue, turns its gaze to ARCHITECTURE FOR THE COMMUNITY IN LATIN AMERICA. There are currently many institutional and/or private initiatives that focus their attention on solving social problems on the basis of suitable economic, sustainable and morphological projects. These are proposals that contemporarily dissipate the needs that have arisen in basic collectivities. This issue seeks to highlight those works of a notoriously public nature that have emerged within the heart of different communities; works that sometimes use the traditional materials of the places where they are located, to deploy them in a contemporary way.
“Suelo propio y originario”: Manuel Quintín Lame y sus pensamientos sobre el espacio durante “La Quintinada” (1910-1922)
Authors: Gutiérrez Ferro Santiago Enrique
Published: December 2021

Este trabajo se aproxima a la forma en la cual Manuel Quintín Lame, líder indígena de inicios del siglo XX, dotó de signifi cado el espacio que habitaba y en el cual surgiría un movimiento supraétnico de resistencia contra el despojo territorial, conocido como “La Quintinada”. Aquí se examinan las visiones que Lame construyó sobre la “tierra” y el “monte” (la “naturaleza”), así como los factores de su contexto histórico/cultural que confi guraron esa forma particular de signifi car. Se propone que Lame concibió la “tierra” como un legado ancestral y un derecho originario y providencial de los pueblos indígenas; a la vez, que entendió el “monte” (“naturaleza”) como un espacio de conocimiento y sabiduría. Todo esto enmarcado en un contexto de movilización y de construcción de una identidad indígena.

Action mechanism: the microabrasion compound modifies light refraction and reflection indexes producing an optical effect which allows the camouflage of the subsurface stains. Indications: the technique is indicated to remove any stain, since it is restrict to the most superficial layer of enamel. Advantages: immediate and permanent results with minimum loss of dental structure. Technique: with all care steps taken, a mixture of hydrochloric acid or phosphoric acid and pumice is applied to dental surface for 12 to 16 times, during 10 seconds each application. The application can be done manually or with the help of a low rotation hand-piece. Conclusions: the enamel microabrasion is an effective, safe and conservative technique if compared with other alternatives available. However, some authors affirm that it must be very carefully used because of enamel loss and risks of lesion by the acid.

This paper is a clinical report of a male patient, who had suffered a left temporal bone fracture. At the Emergency Service, the fracture reduction was performed, with the emporal muscle incision. After two months, the patient presented a deviation to the left side during mouth opening and function limitation. Computadorized tomography and magnetic resonance were perfomed to investigate a condyle fracture or internal dearrangement of the temporomandibular joint. Both revealed the integrity of the structures. So, the temporal muscle generated the problem as a result of wound healing. The patient was submitted to physiotherapy sessions and recovered the temporal muscle function.

Published: December 2021

The implementation of sharia bank performance appraisal models has so far adopted the conventional banking model in terms of evaluating financial performance. Based on this phenomenon, the evaluation of sharia banking performance should use performance measurement based on the maqashid sharia method. The Maqashid Syariah Index (MSI) method has three main objectives, including tahzibal-fardi (educating people), iqamah al-â€˜adl (upholding justice), and jalbal-maslahah (public interest). The research is a quantitative descriptive study, to explain the maqashid syariah index ratio in analyzing the performance of sharia regional development banks in Indonesia. The sample used in the study using purposive sampling. The performance of sharia regional development banks based on the maqashid sharia index approach illustrates that sharia regional development banks in Indonesia in their implementation of sharia operations are more dominant in the goals of Iqmah al-Adl, meaning that regional development banks in Indonesia are more concentrated in terms of applying sharia principles. The sharia regional development bank in Indonesia that has achieved the best performance according to the Maqashid Syariah Index approach is the Aceh Syariah Bank.Â
The Management of Fiat Money or Gold Standard in the Financial System
Authors: Rifqi Lathif Lanafir , Nihayah Ana Zahrotun
Published: December 2021

In recent years, several prominent figures in Islamic Economics have called for a reform of the financial system from the concept of fiat money to return to the gold standard system (dinar dirham).Â The main reason for financial system reform is the perspective that fiat money is considered not resistant to inflation.Â However, the gold standard system is considered to have various weaknesses namely;Â physical size is relatively heavy, is not proven to be anti-inflation based on historical records, high production costs, inefficient utilization of production resources, only benefits certain groups, and is vulnerable to payment deficits.Â In theory, the problem of inflation is caused by the imbalance between supply and demand for money itself. If the money supply is greater than the demand, it will cause inflation.Â Conversely, if the money supply is less than the demand, then the economic activity will not be smooth.Â Therefore, this article believes that inflation is not due to the physical form of money (paper or goldÂ ), butÂ is caused by effective money supply and demand management.Â Therefore, government policies are needed including (a) deregulation of the banking system by nationalizing all banks, (b) playing an active role in intervening in the surge in prices of goods and services (c) promotingÂ ZiswafÂ institutions.

Published: December 2021

Informações de custos podem ser usadas na formação dos preços, todavia o que o mercado pode suportar deve orientar a decisão final. Por esse motivo, a precificação com base na abordagem do valor tem sido recorrentemente recomendada, mas, ainda não frequentemente aplicada nas empresas, sobretudo naquelas do mercado B2B. Logo, o objetivo desta pesquisa foi levantar a associação entre o ambiente de precificação e a formação do preço com base no valor em empresas do mercado B2B. Para tanto, houve a aplicação de um questionário a gestores de empresas associadas à ABINEE. A lógica paraconsistente foi usada para identificar o ambiente de precificação e a matriz de correlação para analisar a relação entre esse ambiente e a formação do preço com base no valor. Os resultados indicaram que as empresas brasileiras que atuam em mercados B2B aderem moderadamente a um ambiente de precificação que pode propiciar a aplicação da abordagem baseada no valor de acordo com a convenção de interpretação exposta por Davis (1976) e Sanches, Meirelles e Sordi (2010). O enquadramento como formador de preços associa-se à adoção da abordagem baseada no valor a um nível de significância de 10%. Não há fatores internos, contudo, associados à adoção da abordagem baseada no valor. Os achados podem indicar que a ausência de barreiras não configura um incentivo, motivando investigações futuras a aprofundar a análise do que estimula a abordagem baseada no valor, já que os estudos prévios focaram na averiguação de obstáculos para a adoção da referida abordagem.

pridonosi poznavanju kulturne, gospodarske i političke povijesti prostora
današnje Hrvatske, ali i Slovenije, Srbije, Austrije te Bosne i Hercegovine. Adamovići
su početkom 18. stoljeća upravljali Valpovačkim vlastelinstvom, a potom u
Slavoniji i Podunavlju posjedovali imanja Čepin, Tenje, Aljmaš, Erdut, Bačko
Novo Selo. S vremenom se obitelj podijelila na čepinsku i tenjsku granu. U
tekstu se donose manje poznati podatci iz povijesti tenjske grane obitelji Adamović, koja je od sredine 19. stoljeća
posjedovala imanje sa sjedištem u Velenju (Slovenija), a obiteljskim vezama
bila u bliskim odnosima s brojnim plemićkim obiteljima Austro-Ugarske
Monarhije. Uz sintezu dosadašnjih publiciranih istraživanja, rad se temelji na
informacijama i arhivskom gradivu nasljednika ove obitelji koji su i danas

The application of heterogeneous photocatalysis process using ZnO
photocatalyst for the degradation of Tartrazine (TRZ) dye in aqueous
solution was investigated in a batch reactor. The estimation, the comparison
of the parameter?s effects and the optimization of the removal yield of TRZ
were realized by using Box-Behnken experimental design (BBD). The results
suggested that the most influential factor on the photocatalytic degradation
of the dye was the initial TZR concentration with an effect of (-23.24), the
second in the order was the amount of the catalyst with an effect of
(+18.09), the third was the reaction time with an effect of (+15.38) and the
fourth was stirring speed with a positive effect of (+4.41). The model
obtained by BBD led to the following optimal conditions for degradation
yield of TRZ: initial concentration of TZR equal to 20.035 mg/L, reaction
time equal to 88.635 min, 0.6409 mg/L of ZnO amount and 404.9 rpm for the
stirring speed, which gave 98.576% of degradation efficiency. The study of
irradiation type effect shows that a solar irradiation gave higher yield
than photocatalysis by UV lamp. The O2?- radicals were the principal active
species responsible of the degradation of TRZ. The BOD5/COD ratio increased
from 0.26 to 0.41 after 60 minutes of photocatalysis under solar light,
indicating the feasibility of coupling the photocatalysis process to
biological treatment for the removal of TRZ.

The purpose of this study was to evaluate the level of food safety knowledge
among cadets of Military Academy in the Republic of Serbia. For that
purpose, a structured, self-administrative questionnaire was designed and
used to assess the level of food handling practices and food safety
knowledge. In total, 120 cadets were involved in the study. For each
participating cadet, the food handling practice score (FHPS) and food safety
knowledge score (FSKS) was calculated by dividing the sum of correct answers
by the total number of correct responses. Additionally, knowledge gaps were
identified for each question. Our results indicated that on the average FHPS
among Serbian cadets was 44.5%, while FSKS was 50.5%. Female cadets showed
better scores compared to males, although this was not statistically
significant. Better FHPS scores were determined among cadets living with
parents (48.7%), compared to cadets living with roommates (43.6%, p?0.05),
while an opposite was determined for FSKS. In total, 95.8% of cadets apply
good practice of hand hygiene before preparing food, 90.8% of them knew that
is not safe to consume food when the shelf-life is expired, and 89.2% knew
that the opened sterilized milk should not be stored outside the
refrigerator. Also, 91.7% of cadets knew that content of blown can is not
safe for the consumption. Almost 64.2% of all cadets could successfully make
association between meat and Trichinella, while merely 27.5% of them knew
that Escherichia coli O157 is the most important pathogen for raw minced
meat, and only 13.3% of cadets knew that Listeria monocytogenes is
associated with ready-to-eat meat products. Finally, only 10% of cadets knew
that Campylobacter is food-borne pathogen mostly associated with raw and
undercooked chicken meat. Also, our cadets were not aware that color, smell
or appearance of food would not give any indication of food contamination,
as only 6.7% of cadets knew this. Results obtained in this study pointed out
some food safety areas which need further improvement via educational
program, but also via media and internet courses, material or short clips.
