Published: February 2022

Colistin is considered as one of a last resort antimicrobial agent against multidrug-resistant Gram-negative bacteria including Escherichia coli and Klebsiella pneumoniae. However, the recent emergence of colistin resistance (ColR) worldwide that severely restricts therapeutic options is a serious threat to global public health. In this study we have investigated the molecular determinants in ColR K. pneumoniae isolates collected from clinical specimens.

A total of 98 E. coli and 195 K. pneumoniae clinical isolates were collected from two hospitals from August 2018 to December 2019 in Tehran, Iran. Colistin susceptibility and minimum inhibitory concentrations (MIC) were determined according to the Clinical and Laboratory Standards Institute by disk diffusion method, and microdilution method, respectively. For isolates with colistin MIC ≥4 μg mL−1, PCR was performed for the detection of mcr-1 to mcr-4 genes. Moreover, nucleotide sequences of mgrB, phoP, phoQ, pmrA, and pmrB genes were determined by sequencing. Finally, the transcriptional level of pmrK and pmrC genes was evaluated by quantitative reverse transcription PCR (RT-qPCR).

None of the E. coli isolates were resistant to colistin while 21 out 195 K. pneumoniae isolates were identified as resistant, 19 of which carried mutation in the mgrB gene. Three different mutations were observed in the pmrB gene in 3 K. pneumoniae isolates. None of the ColR isolates showed alternations in pmrA, phoP, and phoQ genes. Furthermore, none of the plasmid-encoding genes were detected. Transcriptional level of the pmrK gene increased in all ColR isolates meanwhile, pmrC overexpression was detected in 16 out 21 (76.19%) isolates. Eventually, all ColR isolates were susceptible to tigecycline. Our results demonstrated that the alternation of mgrB gene is the main mechanism related to colistin resistance among ColR K. pneumoniae isolates in this study.

Testing ANOVA Replications by Means of the Prior Predictive p-Value
Authors: Zondervan-Zwijnenburg Mariëlle , Van de Schoot Rens , Hoijtink Herbert
Published: February 2022

In the current study, we introduce the prior predictive p-value as a method to test replication of an analysis of variance (ANOVA). The prior predictive p-value is based on the prior predictive distribution. If we use the original study to compose the prior distribution, then the prior predictive distribution contains datasets that are expected given the original results. To determine whether the new data resulting from a replication study deviate from the data in the prior predictive distribution, we need to calculate a test statistic for each dataset. We propose to use ̄F, which measures to what degree the results of a dataset deviate from an inequality constrained hypothesis capturing the relevant features of the original study: HRF. The inequality constraints in HRF are based on the findings of the original study and can concern, for example, the ordering of means and interaction effects. The prior predictive p-value consequently tests to what degree the new data deviates from predicted data given the original results, considering the findings of the original study. We explain the calculation of the prior predictive p-value step by step, elaborate on the topic of power, and illustrate the method with examples. The replication test and its integrated power and sample size calculator are made available in an R-package and an online interactive application. As such, the current study supports researchers that want to adhere to the call for replication studies in the field of psychology.
Dependent bourgeois revolution and Brazilian political model, 1971-2021
Authors: Singer André
Published: February 2022

The article takes up categories proposed by Fernando Henrique Cardoso in 1971 to analyze the 1964 coup and the military dictatorship. Based on them, an attempt is made to interpret aspects of the political process from the impeachment of Dilma Rousseff to the third year of Bolsonaro's government. The idea of “bourgeois dependent revolution”, which Cardoso associates with the economic miracle that occurred approximately from 1967 to 1976, is used to understand the meaning of the 2016 parliamentary coup. The notion of “military-bureaucratic autocracy”, used by Fernando Henrique, to characterize the dictatorial regime, is compared to the current alternatives of semi-presidentialism, fascist-biased autocratism and the return to the democracy of 1988.

This second part presents some views on the development of our current reservoir inspection practice and how we might take this forward in a manner that can provide greater consistency, particularly in a world where inspecting engineers are unlikely to have had the richness of experience that was available to previous generations.
A Map of the Current Cultural Climate in Medicine and Healthcare, and How We Can Change It
Authors: Rani Savita
Published: February 2022

In Canada, healthcare and medicine are grounded in structures of coloniality, oppression, heteropatriarchy and a variety of “-isms” (racism, sexism, ableism, classism). Consequently, it is little wonder that deep-rooted, enduring health disparities exist for many different groups across Canada. The COVID-19 pandemic has only served to exacerbate these disparities. Clearly, something needs to change in healthcare delivery and education. Comics are an ideal medium to document this moment, as well as catalyze change, for many reasons. Graphic Medicine – the creation and study of comics in healthcare contexts – can be used to explore the current discourses and cultures of healthcare and bring diverse perspectives into dialogue. Comics are also inherently disruptive. They challenge what is considered acceptable as discourse, and therefore knowledge, within medicine. They are also accessible to anyone with a writing tool, surface, and an idea to share. In this way, comics help democratize communication and give oft-ignored voices the ability to help shape medical discourse. Additionally, the diversity of forms and features used in comics creation directly relates to and enhances the diversity of voices, perspectives and lived experiences expressed in comics. Graphic Medicine can be a tool to advocate for health equity across populations.
The Worst of Both Worlds: The Familiar's E-Books and Their Unhandy Limitations.
Authors: Ezerin Ian
Published: February 2022

The commercial longevity and actual continuity of Mark Z. Danielewski’s series The Familiar was, by default, subject to the audience’s enthusiasm about it. But the latter hinges on a number of factors, which include not only the appeal of the plot and the author’s cult status, but also, importantly, the material conditions of the reading experience and the broader patterns of the economics of contemporary publishing industry. The argument of this essay considers the characteristics and effects of The Familiar’s somewhat inglorious digital incarnation, to infer that the absence of a ‘proper’ (i.e. medium-specific) and functional (i.e. responsive to highlighting, annotations, word selection and search, translation, and other functions afforded by digital devices) e-book edition significantly factored into the causes of the “pause” in the series’ progression, announced by the writer on February 2nd, 2018.
Sobrepoblación y buena conducta: tensiones vinculadas al derecho a la educación en las cárceles de Buenos Aires
Authors: Pérez Camila
Published: February 2022

En este artículo se abordan las tensiones en los marcos normativos que regulan la vida y el derecho a la educación de las personas privadas de libertad y su distancia respecto a las extremas condiciones de vida en las cárceles de Buenos Aires . En particular, se analiza el valor otorgado al concepto de buena conducta, sostenido en la Ley 24.660/96 de Ejecución de la Pena Privativa de la Libertad, para reflexionar sobre el tratamiento penitenciario y sus tensiones, mediante el abordaje etnográfico de un taller de alfabetización realizado en el año 2017 en la Unidad Penitenciaria 47. Los resultados de la investigación permiten afirmar que los elevados índices de sobrepoblación registrados imposibilitan el orden, la disciplina y la convivencia dentro de los establecimientos penitenciarios e intensifican las dificultades de acceso y la permanencia de los participantes en el espacio educativo.
Abstract
In this article I am interested in exposing the tensions that exist in the normative frameworks that regulate the life and right to education of prisoners and their distance from the extreme living conditions of Buenos Aires prisons. I will analyze the value given to the concept of good conduct upheld in Law 24.660 / 96 to advance prison treatment and its tensions through an ethnographic approach of a literacy workshop held in 2017 in Penitentiary Unit 47. The results of the investigation allow us to affirm that the high rates of registered overcrowding make order, discipline, and coexistence impossible within prison establishments, and intensify the difficulties of access and the permanence of the participants in the educational space.
Fuerzas armadas y pandemia en Argentina (2020-2021): profesionalización militar ante la asignación de misiones subsidiarias
Authors: Anzelini Luciano
Published: February 2022

El artículo estudia el papel de las Fuerzas Armadas argentinas ante la emergencia sanitaria por COVID-19, tomando como referencia la expansión del rol castrense en América Latina en el contexto de la pandemia. El objetivo es mostrar que, a diferencia de lo que advierten algunos analistas acerca de los peligros para la democracia en otros países de la región, la asunción prolongada de esta misión subsidiaria por parte de los uniformados argentinos no ha revelado consecuencias negativas. La investigación combina herramientas conceptuales de la ciencia política y del estudio de las relaciones civiles-militares, y emplea un diseño teórico-metodológico cualitativo, ajustado al método conocido como “estudio de caso desviado”. Se concluye que en el accionar de las Fuerzas Armadas argentinas ante la pandemia han convergido factores políticos, normativos y operacionales que explican el éxito de la “Operación General Belgrano”.
Abstract
The article sets out to analyze the role of the Argentine armed forces in the face of the COVID-19 health emergency, taking as a reference the expansion of the military role in Latin America in the context of the pandemic. The aim is to exhibit that, despite certain experts having warned about the dangers to democracies in other Latin American countries, the prolonged assumption of subsidiary missions by Argentine soldiers has not revealed negative consequences. The investigation combines conceptual tools from political science and the study of civil-military relations, in addition to the use of a qualitative design adjusted to the method known as “deviant case study”. It is concluded that political, normative and professional aspects explain the success of the “General Belgrano Operation”, carried out by the Argentine armed forces to deal with the pandemic.
24/7. Поздний капитализм и цели сна
Authors: Крэри Джонатан
Published: February 2022

Джонатан Крэри исследует некоторые из разрушительных последствий непрерывных и расширяющихся процессов, характерных для капитализма XXI века, когда рынок непрестанно работает в режиме 24/7, подталкивая нас к постоянной активности и подтачивая многие формы общественного и политического самовыражения. Автор прослеживает, как неостановимое невремя размывает границы между вездесущим и безудержным потребительством и складывающимися сегодня стратегиями контроля и надзора; описывает постоянное управление человеческим вниманием и нарушение восприятия в рамках принудительных практик современной технологической культуры. В то же время он отмечает, что человеческий сон, будучи целительной передышкой, по своей сути несовместимой с капитализмом 24/7, указывает нам на другие, более грозные и более коллективные способы отказа от разрушающих мир моделей роста и накопления.

Authors: Vásquez-Vargas Kléver
Published: February 2022

El siguiente estudio se enfocó en las prácticas artísticas desarrolladas en el espacio urbano por artistas y gestores culturales que se involucran con la vida social y comunitaria de grupos vulnerables y excluidos. Se estudiaron los proyectos presentados en los “Encuentros de arte urbano y comunitario al zur-ich” (2002-2018); realizados en el sur de Quito-Ecuador; sector de extracción popular, obrera y campesina. Los proyectos artísticos se midieron y analizaron en su aspecto comunicacional y espacial, basándose en las categorías que James Scott encontró en las prácticas políticas de los “dominados”, y relacionándolas con la delimitación espacial que, según Michel de Certeau, produce el relato como relato de viaje.Los resultados dieron cuenta de un espacio urbano "oculto" en lo comunitario, donde sus prácticas, con características estéticas propias, evocan el vínculo existente entre arte y política.

It may be said that COVID-19 eased the nature from human pollution. Present paper may argue this perception by analyzing the connection between the economic impact before and after the COVID-19 outbreak, measured by national GDP and the level of pollution in the European countries, referring to air and water pollution. A simple linear regression model with two control variables was applied in order to obtain the results (the control variable were the number of COVID-19 cases and the austerity measures applied in the countries, in the specified period, classified by the impact over the labor productivity). Data was aggregated using the population values for each country and normalized using log normalization method. The paper also engages a multivariable regression, with exogenous variables composed of all NACE REV 2 activities that contribute to national GDP and endogenous variable being the composite pollution index (based on air and water pollution indicators). The control variables applied in the multivariable regression are the same as the ones described below. Results show that DGP dropped with 16.26 % from Q4 of 2019 to Q2 of 2020 and with 5.86 % from the same period of last year till second semester of this year, based on the austerity measures taken in order to stop the spreading SARS-CoV-2, especially the ones considering non trivial activity closure or entire sector closure. Findings include also a percent of 30% of air quality improvement (in terms of particle matter presence) during COVID-19 lockdown in Europe, that had a positive impact even after lockdown was suspended and a general water quality improvement of 32 % from 2018 to 2020. A moral problem is presented in the present paper: did COVID-19 killed or saved many lives, due to air pollution reduction, while fatality rate of COVID-19 is 1.4 % [40] and air pollution fatality rate was 7.6 % in 2016 [18], before air quality improved?

The aim is to determine the degree of agricultural development of the lands of Volyn region. Method. The agricultural development of the lands of the Volyn region by administrative-territorial districts is determined. General scientific and static methods, methods of system and structural analysis, comparative geographical and graphic methods are applied. Regional statistics were processed. The formulas for determining the agricultural development of lands, coefficients of plowed lands and plowed agricultural lands are given. Results. Agricultural development of the territory is defined as the ratio of the area of agricultural land to the total land area, excluding areas under water and swamps. As a result of calculations we determined that the highest indicator of agricultural land development of Volyn region is 78-80%, and is the highest for Rozhysche, Lutsk and Gorokhiv districts of the region, the degree of agricultural land development is the lowest for Kamin-Kashirsky, Lyubeshiv, Manevychi and Shanevytsia. The average value of the coefficient of agricultural development for the territory of Volyn region is 56.6%. or the entire territory of Volyn region, the coefficient of plowing of the land territory is 38.13%. The highest percentage of plowed lands of the region is typical for the southern forest-steppe regions of the region. Based on the analysis of the plowing coefficient, the territory of Volyn region is assessed as «conditionally favorable». Plowing of agricultural lands in modern conditions characterizes the intensity of agricultural production and ecological tension of the territory. The highest coefficient of plowing of agricultural lands is typical for the territories of Gorokhiv district (88.34%), Lutsk (86.48%), Lokachyn (85.34) and Ivanychiv (82.7) districts, the lowest coefficient of plowing of agricultural lands is observed in the territories of Lyubeshivsky Ratnivsky and Lyubomlsky administrative-territorial districts of Volyn region. The average plowed agricultural land for the territory of Volyn region is 64.72%. Thus, for forest-steppe areas this indicator is higher. Thus, for forest-steppe areas this indicator is higher. Scientific novelty. The typology of administrative-territorial districts of Volyn region according to the degree of agricultural development and the coefficient of plowing of lands (including agricultural lands) is carried out. Practical significance. The results of the studies reveal the condition of lands in the Volyn region. Can be used to determine the potential productivity of land resources in the region. Determining the level of transformation and rational efficiency of their use.
A Novel Storage Virtualization Scheme for Network Storage Systems
Authors: Yang Jui-Pin
Published: February 2022

The network storage systems are generally composed of clients, storage servers and metadata servers. In this paper, we proposed a novel storage virtualization (NSV) scheme which is capable of alleviating the heavy load of metadata server, guaranteeing the storage quality of service and dynamically adapting storage resources. The metadata server automatically constructs a dedicated storage cluster according to various requirements of storage quality of service. The storage cluster may consist of one to many storage servers which includes one master storage server and zero to many slave storage servers. In other words, a network storage system consists of at least one storage cluster. The requests of each client are forwarded to corresponding master storage server within a specific storage cluster. In addition, the master storage server determines the best storage server which handles the requests based on the conditions of storage servers. Next, the requests will be redirected to the selected storage server. Finally, the responses are directly transmitted to the client.

Published: February 2022

Abstrak. Kualitas biochar sangat bergantung kepada bahan baku, lama pembakaran dan temperatur pembakaran. Kandungan senyawa kimia seperti selulosa, hemiselulosa dan lignin yang terdapat dalam bahan baku akan mempengaruhi biochar yang dihasilkan. Rendah dan tingginya temperatur pembakaran akan mempengaruhi sifat biochar (hidrofobik menjadi hidrofilik), mempengaruhi jumlah pori-pori pada biochar sehingga menghasilkan luas permukaan spesifik yang tinggi. Semakin tinggi luas permukaan spesifik pada biochar akan meningkatkan retensi air dan kapasitas tukar kation. Penelitian ini mengkaji kualitas sekam padi akibat pembakaran secara pirolisis dengan menggunakan dua dari tiga indikator kualitas biochar yaitu variasi temperatur pembakaran dan bahan baku. Penelitian ini dilaksanakan di Laboratorium Fisika Tanah dan Lingkungan Universitas Syiah Kuala. Alat yang digunakan dalam penelitian ini adalah chamber muffler dengan temperatur pembakaran yang diatur pada 400oC dan 800oC dengan waktu pemanasan masing-masing 4 jam. Hasil penelitian ini menunjukkan bahwa temperatur pembakaran dan bahan baku pembuatan biochar berpengaruh terhadap semua variabel karakteristik biochar yaitu rendemen, kadar air, kemampuan memegang air, pH, daya hantar listrik, zat menguap, kadar abu, karbon terikat. Rice Husk Biochar Characteristisc at two pyrolysis temperatureAbstract. The quality of biochar is highly dependent on the raw materials, duration of combustion and combustion temperature. The content of chemical compounds such as cellulose, hemicellulose and lignin contained in the raw materials will affect the biochar produced. Low and high combustion temperatures will affect the nature of the biochar (hydrophobic to hydrophilic), affecting the number of pores in the biochar resulting in a high specific surface area. The higher the specific surface area of the biochar, the higher the water retention and cation exchange capacity. This study examines the biochar quality of   rice husks due to pyrolysis combustion using two of three indicators of biochar quality, namely variations in combustion temperature and raw materials. This research was conducted at the Laboratory of Soil and Environmental Physics, Syiah Kuala University. The tool used in this study is a chamber muffler with a combustion temperature set at 400oC and 800oC with a heating time of 4 hours each. The results of this study indicate that the combustion temperature and raw materials for biochar have an effect on all variables of biochar characteristics, namely yield, water content, water holding capacity, pH, electrical conductivity, volatile matter, ash content, and fixed carbon.

Nowadays, consumers tend to search for additional source of protein and energy for their dietary consumption, for instance from legumes and nuts. This trend is getting more common since the increase case of lactose intolerance. This study aims to study the effect of the formulation of materials consisting of a mixture of two or three types of nuts and the CMC (Carboxy Methyl Cellulose)  on the quality characteristics of plant milk and consumer preferences towards the produced plant milk. The method used in this study was a factorial completely randomized design (FCRD). This study were used combination of two or three types of beans, namely soybeans (KK), peanuts (KT), green beans (KH). The first factor was formulation of raw materials (K1 = 50% KK: 50% KT: 0% KH, K2 = 50 % KK: 0% KT: 50% KH, K3 = 0% KK: 50% KT: 50% KH, and K4 = 33.3% KK: 33.3% KT: 33.3% KH). In addition, CMC was used as a stabilizer by treating different concentrations of CMC (C1 = 0.20% and C2 = 0.40%). Anova continued with DMRT0.05 determined that plant milk with the best treatment is K1C2 with the formulation of 50% peanut: 50% soybean and the addition of 0.4% CMC. The KIC2 treatment had values: protein content 3.87%, fat content 14.74%, pH 6.62, total dissolved solids 11.47oBrix. For consumer acceptance with RATA (Rate All That Apply) method, researchers found out that K1C2 has milky white color (89% of respondents), peanut aroma flavour (78% respondents), sweet (48%) and savory (37%) taste, thick and homogenous texture (44% respondents) with overall hedonic liking 3.11 or neutral.

Kaplice kolegiaty św. Anny w Krakowie – indywidualne fundacje pod zbiorczym nadzorem
Authors: Kurzej Michał
Published: February 2022

Krakowska kolegiata św. Anny jest przykładem rzadkiej sytuacji, w której odrębne finansowanie poszczególnych kaplic udało się pogodzić ze ścisłym zintegrowaniem ich wystroju z całością wnętrza, ale też bardzo specyficznej komemoracji ich dobrodziejów. Upamiętniono ich w książce wydanej z okazji konsekracji, co stanowiło specyficzny wyraz kultury akademickiej, skoncentrowanej na słowie pisanym, a także odwołującej się często do księgi jako uniwersalnego symbolu mądrości. W kościele św. Anny jest to główny motyw wnętrza, powtarzający się jako atrybut patronki, spis ziemskich przodków jej wnuka, dowód świętości Jana Kantego, znak wiedzy antycznych prorokiń oraz godności Baranka Apokaliptycznego jako Najwyższej Mądrości Bożej.

Published: February 2022

Foreign Direct Investment (FDI) is one of the global economic systems. FDI is able to encourage the economic development of a country quickly, but there are problems that must be faced and of course become a challenge for the host countries, namely the presence of investors is strongly influenced by the internal conditions of a country, such as economic stability, state politics, law enforcement and others. This research investigates the relationship and significance of macroeconomic variables to FDI in two countries namely Indonesia and Malaysia in the period 1989 to 2018.The method of analysis used Pooled Least Square (PLS). GDP variables have a positive but insignificant effect on the FDI levels in Indonesia and Malaysia. The test results on exports also showed the same thing that export variables give test results positive and insignificant influence on FDI variables.
Perspectivas de análisis desde lo local
Authors: Benayas Sánchez David
Published: February 2022

Este trabajo se marca como objetivo perfilar un itinerario de trabajo de cara a las investigaciones relacionadas con la Historia local, los estudios de caso y la memoria de acontecimientos históricos traumáticos. Desde el marco de análisis de la etnometodología para los relatos memoriales y el apoyo en la interpretación de las fuentes documentales y la reciente producción bibliográfica se pretende analizar desde una perspectiva microhistórica el trazo que el sistema de violencia de los sublevados dejó en un individuo y su familia, la repercusión que tuvo en el pueblo la violencia perpetrada durante la guerra y la posguerra, y las lógicas y dinámicas que emanaron de la misma.
La revista Atlántida (1963-1972)
Authors: Díaz Hernández Onésimo
Published: February 2022

En 1963 aparecieron las revistas Cuadernos para el Diálogo, Revista de Occidente  y  Atlántida. Las dos primeras han sido objeto de libros y artículos, mientras la tercera apenas ha sido investigada. Este artículo examina qué se pretendía con esta revista, quiénes la hicieron posible y cuál era su línea de pensamiento, es decir, qué decía y cómo lo decía. La fuente principal es el archivo personal del promotor y director de Atlántida, Florentino Pérez-Embid, consultado en el Archivo General de la Universidad de Navarra. He seguido el hilo cronológico de los acontecimientos desde los primeros esbozos, la aparición de los primeros números hasta la crisis y desaparición de la publicación en 1972. Todo parece apuntar a que Atlántida se cerró por la falta de dedicación de tiempo de su director, ocupado con la dirección general de Bellas Artes y el rectorado de la Universidad Internacional Menéndez Pelayo.
El laberinto marroquí, piedra de tropiezo de liberales y autoritarios (1912-1926)
Authors: La Porte Pablo
Published: February 2022

Los intereses coloniales de España en Marruecos se vieron circunscritos por el equilibrio de fuerzas establecido por Inglaterra y Francia en el Mediterráneo Occidental. Las ambiciones españolas se vieron también obstaculizadas por la rivalidad con Francia, su vecino colonial en Marruecos, que determinó la problemática naturaleza del proyecto marroquí para España y su influencia adversa sobre la política peninsular.
Imaginarios y conmemoración del fin del ‘problema’ de Marruecos durante la dictadura de Primo de Rivera
Authors: Iglesias Amorín Alfonso
Published: February 2022

Resulta difícil comprender el régimen instaurado en España en 1923 sin tener en cuenta el protectorado de Marruecos. La dictadura fue en parte consecuencia del desastre de Annual, y solucionar el “problema de Marruecos” uno de sus grandes objetivos. El haberlo conseguido tras el desembarco de Alhucemas llevó al régimen a convertir lo que entonces se denominó como “pacificación” en un mérito portentoso, utilizado para legitimar la dictadura y a su líder. Por ello, la conmemoración relativa a la guerra de Marruecos fue un elemento central de la propaganda primorriverista. Destacaron la realización de homenajes y la concesión de méritos a los protagonistas, así como un control de los productos culturales a través de la propaganda y censura, que aseguraron la adaptación de éstas al discurso oficial del régimen. Precisamente el análisis de este discurso interesado resulta de gran interés para conocer la orientación del régimen y la construcción de una determinada memoria de las campañas marroquíes.
Arqueologia pedagógica
Authors: Samia Danielle Gomes
Published: February 2022

A arqueologia no Brasil, vem sendo desenvolvida em geral desconectada das práxis pedagógicas. O objetivo deste artigo, é alcançar uma proposta para reduzir essa desconexão, com fomentação da pedagogia arqueológica articulada à correntes teóricas para o desenvolvimento de conteúdos que proporcionem autonomia. Esta fomentação perpassa pelo entendimento que a pesquisa arqueológica, não é uma atividade tecnicista, e que deve ser integrada as humanidades com a promoção de interações que proporcionem conexões com as pessoas e suas memórias, ancestralidades e práticas. Sendo necessário compreender que a pedagogia arqueológica não deve estar centrada em descrever os registros arqueológicos e/ou na formulação de sínteses com linguagem abstrata, mas deve buscar mostrar as conexões com as sociedades dos lugares onde a investigação é realizada.

Neste artigo apresentamos o resultado de um estudo que teve como objetivo compreender o processo educativo proposto pelo Projeto Aprendendo com os Povos Indígenas, PACPI e as contribuições da Arqueologia por meio de evidências científicas para a aprendizagem e o reconhecimento do patrimônio cultural dos povos originários, a valorização de suas identidades e percepções de ambiente e natureza. O projeto foi realizado com crianças do Primeiro Ano do Ensino Fundamental I do Colégio UNESC, localizado no município de Criciúma, SC, no ano de 2018. A abordagem foi qualitativa tendo a observação participante e a análise documental como técnica e escolha metodológica. Os dados mostraram que as atividades desenvolvidas por meio de visitação, oficinas e registros no decorrer do projeto provocaram engajamento, reflexão e empatia dos estudantes para com os povos indígenas e seu patrimônio cultural. Concluiu-se por meio desse estudo que é imprescindível um processo pedagógico de educação patrimonial qualificado, que proporcione experiências e ações significativas aos estudantes, capazes de desenvolver um olhar de compaixão, respeito e admiração aos povos indígenas, à sua história, seus costumes e sua cultura.
Educação como canal de comunicação arqueológica/museológica
Authors: Lassance José
Published: February 2022

Este artigo é resultado de uma pesquisa realizada no âmbito do Mestrado Profissional do Instituto do Patrimônio Histórico e Artístico Nacional (IPHAN) onde, por meio de uma análise bibliográfica, foram examinados os Projetos Integrados de Educação Patrimonial (PIEP) na alçada da Instrução Normativa IPHAN nº 001/2015. Este estudo teve como objetivo traçar um panorama conceitual dos PIEPs por meio das referências utilizadas pelos projetos, a fim de identificar potencialidades e fraquezas no desenvolvimento da Educação Patrimonial no contexto do Licenciamento Ambiental, mais especificamente no campo da Arqueologia, tendo como recorte projetos disponíveis na base de dados do SEI/IPHAN-RS. Desse modo, apontaremos durante o texto alguns dos problemas identificados e sugerimos uma maior aproximação entre as cadeias operatórias da Arqueologia e da Museologia, com foco nas atividades educativas, como metodologia para a comunicação dos conhecimentos gerados nas pesquisas.
