Authors: Suyadi Suyadi
Published: August 2021

Tujuan dari penelitian ini adalah untuk mengetahui efektifitas pendekatan BCCT dalam pengembangan kecerdasan linguistik (berbahasa Inggris) pada anak usia dini.  Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan mendeskripsikan bagaimana pengenalan bahasa Inggris pada anak usia dini yang dilaksanakan di Kelompok Bermain Insan Terpadu (KBIT) Insan Mulia Bantul yang meliputi kegiatan pengenalan Bahasa Inggris tentang warna, nama-nama binatang, mengenal angka, mengenal nama-nama kendaraan dan buah-buahan dengan lagu, bernyanyi sebelum dan sesudah kegiatan sentra, serta dalam kegiatan fisik motorik. Kesimpulan penelitian ini adalah bahwa dengan sering mengajak anak bernyanyi, bermain baik dalam kegiatan sentra maupun kegiatan yang lain dengan bahasa Inggris maka akan semakin banyak kosa kata bahasa Inggris yang dimiliki anak. Selain itu anak tidak merasa terbebani dengan pemebelajaran yang sulit karena dilakukan dengan permainan yang menyenangkan dan membuat anak tidak bosan. Tema yang diberikan adalah yang berkaitan dengan apa yang keseharian dijumpai oleh anak misalnya sapaan, nama-nama binatang, pengenalan warna, bentuk, anggota tubuh, pengenalan angka, alat transportasi akan membantu memudahkan anak mengasosiasi pengetahuan dengan lingkungannya
Mother Earth, Mother Africa and African Women’s Role in Indigenous Religions
Authors: Kaunda Mutale Kaunda
Published: August 2021

This paper explores the nexus between African indigenous religio-culture and ecology, gender, rituals and the environment, in current ritual debates. Current debates demonstrate that ritual has filtered into the public space thereby being resilient and at the same time vulnerable to exploitation by the public sphere. Examining the current debates on rites of passage, this article reviews four chapters from the book Mother Earth, Mother Africa and African Indigenous Religions. African indigenous rituals are spaces that produce knowledge for African ways of living. However, in search of progress, development and better life, most African people have been neglecting rites as they seem unprogressive. In ritual spaces, the novices were instructed about how to engage with nature and how to live with others within communities. Ritual spaces gave women and men (initiates) agency over a vast number of life issues. Drawing on African feminist cultural hermeneutics, I examine ritual functions as a tool to understand how contemporary African people’s search for justice can be gleaned within such African rituals in order to uplift women’s agency.
Fotografía Latinoamericana Contemporánea: imaginarios, archivos y memoria. Una aproximación a la obra de Milagros de la Torre
Authors: Rigat Leticia
Published: August 2021

En el presente ensayo nos proponemos realizar una lectura de la obra “Bajo el sol negro” (1991-1993) de la peruana Milagros De la Torre, donde se presenta un conjunto de retratos en los que la artista resignifica la práctica fotográfica de los minuteros, muy popular en Cuzco a principios del siglo XX. Nuestro objetivo es considerar cómo, desde el arte contemporáneo, De la Torre produce una obra en la que genera una nueva red de significaciones en torno a la representación de la sociedad peruana. Una serie de fotografías que pueden relacionarse a los conceptos de pureza de sangre, raza, y color de la piel como conjunto estructurador del orden social en la colonia, un orden que continuó luego de la constitución de los Estados Nacionales en América Latina bajo nuevos colonialismos internos.
“Ahora que lo antiguo se ha vuelto moderno”: los pioneros del nuevo tango canción en la década del noventa
Authors: Winokur Julia
Published: August 2021

En este trabajo nos proponemos analizar las primeras formaciones de tango aparecidas en la década de los noventa lideradas por cantautores. Nos enfocaremos en la primera producción discográfica de tres artistas, “Acho” Estol, “Tape” Rubín y Juan Vattuone, por considerarlos iniciadores de una nueva generación y por su vasta producción e influencia en los compositores y autores que les siguieron. Encontramos que estos músicos eligen como tradición la estética del tango de las décadas del veinte y el treinta, previo a la ‘década de oro’, cristalizada en el imaginario social como el tango. Esto se puede ver tanto en la instrumentación como en la poesía, que recupera el humor y la denuncia social que el tango perdió posteriormente. Sin embargo, esta tradición no se toma en forma de homenaje ‘puro’, sino combinando estos elementos con rasgos del rock nacional, el blues y el folclore, y mezclando tópicos clásicos del tango con temas y vocablos de la actualidad.

The Role of Warhol’s Brillo soap boxes on the Contemporary Aesthetics, based on the “Applied Ontology” Theory of Roger Pouivet
Authors: Zabolinezhad Hoda , Shad Qazvini Parisa
Published: August 2021

This paper, based on Roger Pouivet’s “applied ontology” theory, studies the effect of Warhol’s Brillo soap boxes, a work that could not convince the art world, when it was first shown, to accept it as an art piece. We strive to answer two questions: In the contemporary age, what aesthetic criteria turn a human-made work into an artwork? And deriving from Pouivete’s “applied ontology” theory, how is a contemporary artwork considered as the personal symbols of the artist and how are the aesthetic characteristics of the work received? An artwork in any style, form and content, includes contextual and formal symbols. In the contemporary age, this becomes a mix of personal symbols and already known collective symbols of a culture that together play a defining role in the creation of the artwork. In other words, a work will be recognized as an artwork when it is the subject of arguments among art experts, even without needing to reach any consensus.

Published: August 2021

Numerous compounds derived from natural sources such as microbes, plants, and insects have proven to be safe, efficacious, and cost-effective therapeutics for human diseases. This study examined the bioactivities of propolis, a structural sealant and antibacterial/antifungal agent produced by honey bees. Chinese propolis was extracted in methanol or hexane. Propolis significantly reduced the numbers of viable cancer cells when applied as a methanol extract (IC50 values in μg/mL for the indicated cell line: MDA-MB-231, 74.12; LoVo, 74.12; HepG2, 77.74; MCF7, 95.10; A549, 114.84) or a hexane extract (MDA-MB-231, 52.11; LoVo, 45.9; HepG2, 52.11; MCF7, 78.01; A549, 67.90). Hexane extract also induced apoptosis of HepG2 cells according to activated caspase-3/7 expression assays (17.6 ± 2.9% at 150 μg/mL and 89.2 ± 1.9% at 300 μg/mL vs 3.4 ± 0.4% in vehicle control), suppressed the growth of Candida albicans and multiple multidrug-resistant and nonresistant Gram-positive bacteria, and inhibited croton oil-induced skin inflammation when applied as topical treatment. GC-MS identified hexadecanoic acid methyl ester as a major constituent (33.6%). Propolis hexane extract has potential anticancer, antimicrobial, and anti-inflammatory activities.
Features of EU Involvement in the Negotiation Process on the Transnistrian Settlement (1994–2005)
Authors:   Russian Presidential Academy of National Economy and Public Administration, North-Western Institute of Management, Shevchuk Nina
Published: August 2021

The theme of the article is the EU participation in the transnistrian settlement with an emphasis on its observer status in the 5+2 format. It covers the period from the beginning of the negotiation process in 1994 until the EU gained observer status in 2005. Based on historical material, the author shows how the EU was gradually involved in the Transnistrian settlement process and how European mediation evolved, using political and economic tools more actively than the methods of traditional diplomacy. The author identified factors that affect the EU's interaction with the parties to the conflict and including – Russia. At the same time, the author focused on the tools used by the European Union in the conflict region even before its official involvement in the negotiations, including the introduction of sanctions against the leadership of Transnistria. The article also explores the essence of the institution of observer on the example of the EU participation in the negotiations in the "5+2" format. It is shown that the external participants in the negotiations on the Transnistrian settlement are equal, despite the difference in their official status. The Europeanization of the Transnistrian settlement failed to energies the negotiation process and increase its productivity, but it allowed the European Union to test new mediation tools, optimize approaches to the settlement of a modern international conflict, and strengthen its position in the conflict region, which remains a zone of geopolitical competition between Russia and the West.

Development and validation of a risk score model for prediction of lower extremity arterial disease in Chinese with type 2 diabetes aged over 50 years
Authors: Zhang Xiaomei , Xu Zhangrong , Ran Xingwu , Ji Linong
Published: August 2021

Background

Lower extremity arterial disease (LEAD) is highly prevalent in people with diabetes in China, but half of cases are underdiagnosed due to diversities of clinical presentations and complexities of diagnosis approaches. The purpose of this study was to develop a risk score model for LEAD to facilitate early screening among type 2 diabetes (T2DM) patients.

Methods

A total of 8313 participants with T2DM from the China DIA-LEAD study, a multicenter, cross-sectional epidemiological study, were selected as the training dataset to develop a risk score model for LEAD by logistic regression. The area under receiver operating characteristic curve (AUC) and bootstrapping were utilized for internal validation. A dataset of 287 participants consecutively enrolled from a teaching hospital between July 2017 and November 2017 was used as external validation for the risk score model.

Results

A total of 931 (11.2%) participants were diagnosed as LEAD in the training dataset. Factors including age, current smoking, duration of diabetes, blood pressure control, low density lipoprotein cholesterol, estimated glomerular filtration rate, and coexistence of cardio and/or cerebrovascular disease correlated with LEAD in logistic regression analysis and resulted in a weighed risk score model of 0–13. A score of ≥5 was found to be the optimal cut-off for discriminating moderate–high risk participants with AUC of 0.786 (95% CI: 0.778–0.795). The bootstrapping validation showed that the AUC was 0.784. Similar performance of the risk score model was observed in the validation dataset with AUC of 0.731 (95% CI: 0.651–0.811). The prevalence of LEAD was 3.4, 12.1, and 27.6% in the low risk (total score 0–4), moderate risk (total score 5–8), and high risk (total score 9–13) groups of LEAD in the training dataset, respectively, which were 4.3, 19.6, and 30.2% in the validation dataset.

Conclusion

The weighed risk score model for LEAD could reliably discriminate the presence of LEAD in Chinese with T2DM aged over 50 years, which may be helpful for a precise risk assessment and early diagnosis of LEAD.
The (pro)renin receptor and soluble (pro)renin receptor in choriocarcinoma
Authors: Morosin Saije K , Delforce Sarah J , Kahl Richard G S , Corbisier de Meaultsart Celine , Lumbers Eugenie R , Pringle Kirsty G
Published: August 2021

This study aimed to determine if the (pro)renin receptor (ATP6AP2) changes the cellular profile of choriocarcinomas from cytotrophoblast cells to terminally syncytialised cells and ascertain whether this impacts the invasive potential of choriocarcinoma cells. Additionally, we aimed to confirm that FURIN and/or site 1 protease (MBTPS1) cleave soluble ATP6AP2 (sATP6AP2) in BeWo choriocarcinoma cells and determine whether sATP6AP2 levels reflect the cellular profile of choriocarcinomas. BeWo choriocarcinoma cells were treated with ATP6AP2 siRNA, FURIN siRNA, DEC-RVKR-CMK (to inhibit FURIN activity), or PF 429242 (to inhibit MBTPS1 activity). Cells were also treated with forskolin, to induce syncytialisation, or vehicle and incubated for 48 h before collection of cells and supernatants. Syncytialisation was assessed by measuring hCG secretion (by ELISA) and E-cadherin protein levels (by immunoblot and immunocytochemistry). Cellular invasion was measured using the xCELLigence real-time cell analysis system and secreted sATP6AP2 levels measured by ELISA. Forskolin successfully induced syncytialisation and significantly increased both BeWo choriocarcinoma cell invasion (P < 0.0001) and sATP6AP2 levels (P = 0.02). Treatment with ATP6AP2 siRNA significantly inhibited syncytialisation (decreased hCG secretion (P = 0.005), the percent of nuclei in syncytia (P = 0.05)), forskolin-induced invasion (P = 0.046), and sATP6AP2 levels (P < 0.0001). FURIN siRNA and DEC-RVKR-CMK significantly decreased sATP6AP2 levels (both P < 0.0001). In conclusion, ATP6AP2 is important for syncytialisation of choriocarcinoma cells and thereby limits choriocarcinoma cell invasion. We postulate that sATP6AP2 could be used as a biomarker measuring the invasive potential of choriocarcinomas. Additionally, we confirmed that FURIN, not MBTPS1, cleaves sATP6AP2 in BeWo cells, but other proteases (inhibited by DEC-RVKR-CMK) may also be involved.
Psychological stress – does it affect wound healing?
Authors: Szałwińska Patrycja , Fichna Jakub , Włodarczyk Jakub
Published: August 2021

The skin is the largest organ of the human body and its integrity and ability to regenerate are essential for the maintenance of physiological homeostasis. Any damage to this barrier requires activation of complex cascades which lead to tissue healing and restoration of its proper function. A range of factors, including psychological factors, stress, infections, and underlying disorders such as diabetes or peripheral vascular disease, may interfere with this process and consequently lead to impaired, excessive, and prolonged healing. This article will focus on the impact of stress on the wound healing process, its underlying biological mechanisms, and the influence of psychological factors. Possible ways of minimizing its negative effects on the course of wound treatment will be discussed.
Ocena aktywności in vitro maści SutriHeal® Forte 5% względem Staphylococcus aureus i Pseudomonas aeruginosa oraz linii komórkowych odpowiedzialnych za proces gojenia się rany
Authors: Bartoszewicz Marzenna , Junka Adam
Published: August 2021

Rany przewlekłe powikłane procesem infekcyjnym nadal pozostają nierozwiązanym wyzwaniem dla systemów ochrony zdrowia na całym świecie. Rany przewlekłe, leczone w nieprawidłowy sposób, mogą prowadzić do trwałego uszczerbku na zdrowiu, a nawet do śmierci pacjenta. Zakażenia w tego typu ranach wywoływane są przez drobnoustroje tworzące biofilm, strukturę chroniącą je przed aktywnością antybiotyków. Obecnie w celu zwalczania biofilmu w ranach przewlekłych stosowane są między innymi nieantybiotykowe, miejscowo działające środki przeciwdrobnoustrojowe. W niniejszej pracy podjęto się oceny in vitro aktywności maści zawierającej formułę kwasów żywicznych i lignanów, uzyskanych ze świerku norweskiego względem szczepów metycylinoopornych Staphylococcus aureus i Pseudomonas aeruginosa, a także oceny wpływu maści na linie komórkowe fibroblastów i keratynocytów oraz na poziom produkcji wolnych rodników przez makrofagi. Uzyskane wyniki wykazały przeciwdrobnoustrojową i przeciwbiofilmową aktywność maści, brak efektu cytotoksycznego w określonych stężeniach oraz zdolność maści do redukcji poziomu wolnych rodników. Biorąc pod uwagę specyfikę metodologiczną badań in vitro, uzyskane dane wskazują na potencjalnie wysoką przydatność badanej maści zawierającej formułę kwasów żywicznych i lignanów uzyskanych z Picea abies do leczenia ran przewlekłych powikłanych procesem infekcyjnym.

On the Graphemic Alternance 〈E〉 ∼ 〈I〉 and 〈O〉 ∼ 〈U〉 in Latin Papyri and Ostraca: Some New Remarks
Authors: Barchi Serena
Published: August 2021

This paper intends to provide some data about the occurrence of 〈e〉 and 〈o〉 for Classical Latin (= CL) /1/ and /ŭ/ in Latin papyri and ostraca. In order to carry out a study of the incidence of some grapho-phonological phenomena within documentary texts and to examine to what extent they could be related with parameters of sociolinguistic variation, the examined texts have been collected in a corpus which has been tagged for both linguistic and extralinguistic aspects. This corpus is available in the Data-base CLaSSES (http://classes-latin-linguistics.fileli.unipi.it), created at the FILELI Department of the Uni-versity of Pisa (§ 1). The study will focus in particular on the analysis of this graphemic alternance in the Bu Njem ostraca (§ 2.1); then, it will dwell on the qualitative analysis of three lexemes in Egyptian papyri and ostraca in which a proto-Romance merger between /ĭ/ and /ē/ in /e/ and /ŭ/ and /ō/ in /o/ in tonic posi-tion might be documented. Particular attention is paid to interference phenomena with Greek (§ 2.2).
The Challenges of Islamic Organizations in Promoting Moderation in Indonesia
Authors: Jubba Hasse , Awang Jaffary , Sungkilang Siti Aisyah
Published: August 2021

Two leading Islamic organisations in Indonesia, Muhammadiyah and Nahdlatul Ulama (NU) have moderation in their missionary vision to create a tolerant, open, and civilised society. This paper explores the challenges of realising Islamic moderation in Indonesia, especially those driven by Muhammadiyah and NU. The data used as the basis for the analysis were obtained from interviews and document studies. The challenge of Islamic moderation initiated by these two organisations is the rise of conservative groups, which have received vast space from the data obtained. This paper emphasised that the rise of conservative groups has resulted in weak respect for other groups. There is even a tendency to resist Islamic groups outside their group. This paper is limited to the internal challenges to Islamic moderation in Indonesia carried out by Muhammadiyah and NU, particularly related to the rise of conservative Islamic groups. Therefore, this paper suggests conducting various studies to provide a basic framework for jointly building a commitment to implement Islamic moderation in Indonesia by looking at other civil society organisations.
Embodied Religious Belief: The Experience of Syahadatain Sufi Order in Indonesia
Authors: Mahatma Masmuni , Saari Zarrina
Published: August 2021

Several types of research on religion in Indonesia emphasise more on religious knowledge and belief and less on other approaches such as material aspects.  Religion is always related to material aspects such as mosque buildings, veils or robes for prayer, or holy water obtained from grave visitors. This study uses embodiment approach and material theory of religion to the imposition of special fashion in prayer that gives consequences on awareness and attitude of a new morality in-group cohesion. This study is a case study through participatory observations and interviews of new members of Syahadatain congregation, Cirebon, Indonesia for three years.  The result of the study shows two significant findings namely first, the establishment of rituals through special fashions exerts an influence on discursive awareness and moral behaviour; and second, the driving factor of the emergence of new moral behaviour from the practice is the social gaze. This study recommends the need for the study of material artifacts such as clothing can be an alternative to the study of religion in Indonesia using the embodiment approach.

Induction of sublethal effects for the characterization of Olive groves under different pest management systems
Authors: Gómez-Guzmán José Alfonso , Sainz-Pérez María , González-Ruiz Ramón
Published: August 2021

Abstract Currently, olive grove management in Spain responds to the three following clearly differentiated systems in order of decreasing area: Conventional Management (70%), Integrated Pest Management (IPM) (26%) and Ecological Management (4%) systems. These are characterized by a decreasing dependence on synthetic insecticides and by different soil tillage intensities. They are also subject to different subside regulations and application regimen by the government, so their adequate characterization represents a factor of increasing importance, which is the object of this work.During the years 2017 and 2018, olive groves corresponding to the three types of management were selected, in which two series of plots were established. In one series, Dimethoate 40® was applied, considering plots of the second series as control. After insecticide application, beneficial insects were monitored through the use of chromatic traps.The results allow elucidating two clearly different behavioral patterns in beneficial insects, depending on the use of insecticides: Conventional and IPM management, where repellency reaction is manifested, absent in the Ecological Management. Aspects about the induction of sublethal effects for the characterization of the different pest management systems are discussed.

Abstract Pecan tree (Carya illinoinensis Koch) is a native specie in Northern Mexico and the Southeastern United States, both countries dominate the production of walnuts to worldwide. The objective was to determine starch balance in root and trunk monthly in two varieties (Western and Wichita), during a production cycle. Sampling was systematic. Results in root and stem showed differences in starch concentrations between varieties, Wichita presented higher concentrations than Western. Wichita variety, in both organs, showed better accumulation conditions of starch. In response to higher starch accumulation in this variety its due to biotic and abiotic requirements to develop up are less demanding than other varieties.
PHYSIOLOGICAL AND MORPHOANATOMIC RESPONSES OF Bowdichia virgilioides KUNTH. (FABACEAE) TO GLYPHOSATE
Authors: Oliveira Ana Paula Augusta de , Crispim-Filho Ailton José , Santos Vanessa Ribeirode Souza , Costa Alan Carlos , Silva Kellen Lagares Ferreira
Published: August 2021

ABSTRACT The expansion of agribusiness in Brazil is partly due to the expansion of arable areas in the Cerrado biome, which, consequently, leads to an increase in the use of herbicides, including glyphosate. Therefore, the objective of this study was to evaluate the physiological and morphoanatomic responses of Bowdichia virgilioides Kunth. (Fabaceae), when exposed to the herbicide glyphosate, under controlled greenhouse conditions. In addition, the study proposed to identify possible response patterns of the studied species and provide subsidies for the study of the species in areas affected by the drift of the herbicide. The experimental design was in randomized blocks, with seven doses of the herbicide: 25, 50, 100, 200, 400, 800, and 1200 g i.a ha-1 besides the control (0), with four repetitions each. Gas exchange, chlorophyll a fluorescence emission, chloroplast pigment content, membrane permeability, and visual and anatomical features were analyzed. The results showed that glyphosate is phytotoxic to B. virgilioides because, even at low doses, this herbicide was able to affect all parameters analyzed. There was also confirmation of the presence of phenolic compounds, mainly in the palisade parenchyma. The metabolic alterations presented demonstrated the sensitivity of B. virgilioides to glyphosate. Thus, the observed responses can serve as a tool for diagnosing the effects of glyphosate exposure on this species, present in native areas affected by the drift of this herbicide. Its indiscriminate use poses a risk to Cerrado biodiversity.
Applying analytic hierarchy process (AHP) to identify decision-making in soybean supply chains: a case of Mato Grosso production

Published: August 2021

Abstract: This paper aims to identify and analyze the factors that influence the decision of Mato Grosso’s farmers to produce soybean using the Analytic Hierarchy Process (AHP). We found evidence that decision-making of soybean production is related to rural production aspects such as climate, financing, cost of inputs, and soil quality rather than marketing and logistics. The novelty of this paper is the empirical analysis of the decision-making in agricultural production using AHP. The decision model was created and tested considering 21 farmers and 19 experts linked to the soybean production. Three different scenarios were considered: farmers' view, experts' view, and combined view. Our findings indicate that farmers and experts agree with rural aspects are predominant in the decision to plant soybean. Moreover, logistics have been used as an important flag of soybean competitiveness on international trade by soybean stakeholders in Brazil. However, our results show that logistics impact in the soybean decision-making process is low. Due to data limitation access, this study focuses only on Mato Grosso. However, this study has an exploratory character and presents empirical results that may help to understand soybean production over the country.

Published: August 2021

abstract This study aimed to update the review of Brazil’s Report Card on the prevalence of global physical activity (PA) among Brazilian children and adolescents. This systematic review included an electronic search of eight databases (PubMed, Scopus, Web of Science, LILACS, SPORTDiscus, BIREME, Scielo, and Google Scholar) and a manual search of the references of retrieved studies. Studies published in 2018 and 2019 that assessed global PA among Brazilian youth were included. A narrative approach to the results was adopted. The initial search retrieved 1,892 potentially relevant titles (1,244 titles after duplicate analysis), of which 62 (47 different studies) met all the inclusion criteria. Most updated studies were carried out in Southern (40.4%) and Southeastern (25.5%) Brazil. Six studies provided data from national surveys (12.8%), and one study included preschool children (< 5 years old). Ten studies objectively measured PA (accelerometer or pedometer devices). In the updated studies, the overall proportion of young people who were physically active ranged from 9.8% to 79.6%. Three national surveys reported the prevalence of physically active students, ranging from 18.4% to 78.8%. There was an increase of surveys that objectively measured PA and with children under 12 years of age in the 2018 and 2019 studies. However, important research gaps (e.g., variations in the measurement of global PA), even in the same study, should be considered to improve the monitoring and evaluation of global PA in Brazil.

Published: August 2021

abstract – This study aimed to summarize existing research examining the prevalence of adequate sleep duration or meeting sleep recommendations among Brazilian children and adolescents. A systematic review was conducted on eight databases. The criteria for inclusion were original research, samples including Brazilian children and adolescents (age 0–18), studies that reported variables regarding sleep duration using both objective or subjective measures, school- or population-based surveys with random sampling, and cross-sectional or cohort studies. Of the 54 articles included, only 27 used data from different studies. Most of the studies were conducted in the southern region (n = 17) with only two studies having a nationally representative sample. Two studies included children below age five, and the age group most investigated was adolescents (>10 years old). A majority of the studies used a self-reported questionnaire and showed variability in the cutoff point applied for adequate sleep duration with the most reported being ≥8 hours. The proportion of adolescents who met recommendations or had adequate sleep duration ranged from 15% to 89%. Among children, the prevalence ranged from 17% to 95%. The least variability was observed among toddlers, ranging from 93% to 95%. No consistent gender differences were observed among the gender-stratified groups of children and adolescents across the studies. It can be observed that, because of the wide range of results and the lack of data with national representativeness, the prevalence of sufficient sleep among young people aged below 18 remains undefined in Brazil.

You recall that some of my predecessors in office have decorated their scholarly discourses with stray specimens of humor, and you fear that I may intend to offer in a more wholesale way cruder examples of that commodity. As the seriousness of my purpose becomes apparent, however, your fear is intensified into horror that anyone should propose topics so inappropriate and obnoxious to this assembly as organization and publicity.

Published: August 2021

O artigo elabora uma discussão teórica sobre as potencialidades e a produtividade dos conceitos e estudos barberianos no campo da comunicação – especialmente dos múltiplos mapas elaborados por aquele autor no período de 1987 a 2017 –, visando à compreensão dos fenômenos contemporâneos das vulnerabilidades digitais. Investiga os modos como as diferentes mediações sequencialmente mobilizadas por Martín-Barbero, ao longo de 30 anos, podem colaborar para o entendimento dos impactos dos usos e apropriações das TIC em contextos de hiperconectividade e de big data, acarretando diferentes riscos individuais e coletivos. Metodologicamente, adotamos a pesquisa bibliográfica com foco na análise crítica das abordagens de diferentes autores nacionais e internacionais sobre os fenômenos comunicacionais e informacionais envolvidos com a temática da vulnerabilidade digital.

La vida conectiva se ha acelerado a partir de 2020, momento en que inició la pandemia de covid-19, la cual contribuyó a intensificar algunos procesos de digitalización en marcha desde hacía décadas. Esta vida conectiva también presenta nuevos desafíos, como el capitalismo de vigilancia, la economía de la atención y los intelectos contingentes, formados por potentes algoritmos persuasivos. En este contexto, la edición de Chasqui número 147 se propone como un observatorio de cultura digital transnacional iberoamericana. Para ello, hemos seleccionado 10 artículos que revelan redes significativas, y en que se estudian los comportamientos de los usuarios; se mapean hábitos, usos y costumbres iberoamericanas en redes sociales; se describen formas de organización en el consumo, producción y circulación de contenidos; se analizan técnicas y contenidos utilizados para manipular información y opinión; se describen e identifican en formas de propagar noticias falsas y discursos de odio; y se presentan nuevas propuestas teóricas para entender a Iberoamérica a través del análisis y la lectura de campos como la big data, el machine learning, la Inteligencia Artificial, los algoritmos, o los sistemas de análisis y visualización de datos

Clinical decision support system for decision making in mammary glands thermography
Authors:   , Bastida M. B.
Published: August 2021

A decision tree based system with heuristic weight factors oriented to diagnosis by thermography was developed. The proposed clinical decision support system (CDSS) includes binary decision trees for statistical classification of some diseases of the mammary gland. These include weight constant factors found by the correlation of the variables involved in the development of breast disorders according to the statistical attachment of the thermal features, as well as complementary clinical information (medical history, physical parameters, genetic load and habits, among others), regarding its diagnostic incidence. The certainty of the system for inflammatory disorders is 96%, for fibrocystic mastopathy is 78 %, for fat necrosis is 62% and for breast cancer is 86%. The 14% error is associated to microcalcifications that with the reported thermographic technique it is not possible to differentiate. Thus, it is possible to catalog the risk of a patient having a condition according to the results obtained after conducting a thermal test. Then, with the CDSS the possibility of applying early detection tests in the population suffering from contraindications to perform the others is improved, in addition it allows a comprehensive diagnosis for other patients.
Principal Components by FTIR Spectroscopy as Innovative Characterization Technique during Differentiation of Pluripotent Stem Cells to Pancreatic Cells
Authors:   , Mata-Miranda M. M.
Published: August 2021

Two of the greatest challenges in Stem Cells (SCs) biology and regenerative medicine, are differentiation control of SCs and ensuring the purity of differentiated cells. In this sense, fast, efficient and accurate techniques for SCs characterization and their differentiation into different cell lineages are needed. The aim of this study was to analyse Pluripotent Stem Cells (PSCs) and Differentiated Pancreatic Cells (DPCs) by Fourier Transform Infrared (FTIR) spectroscopy and Principal Component Analysis (PCA). For this purpose, we differentiated PSCs toward DPCs, characterizing the differentiation process at different stages (0, 11, 17 and 21 days) through light microscopy and vibrational spectroscopy. FTIR spectra were analysed with the multivariate method of PCA, using the second derivatives in the protein, carbohydrate and ribose regions. The results indicate that the PCA allows to characterize and discriminate PSCs and DPCs at different stages of differentiation in the analysed spectral regions. From these results, we concluded that the PCA allows the chemically and structural characterization of PSCs and the different stages of their differentiation in a fast, accurate and non-invasive way.
Effect of Microemulsions of Essential Oils on Human Erythrocyte and Pathogens Bacteria
Authors:   , López M. A.
Published: August 2021

The aim of the study was to evaluate the effect of microemulsions of rosemary (AER) and tea tree (AET) essential oils on human erythrocyte and pathogen bacteria. Microemulsions of each oil were prepared at 8.0% (v/v), 5.0% (v/v) and 2.5% (v/v), and they were tested on human erythrocyte to determine the hemolysis percentage, hemolysis inhibition percentage and the antibacterial capacity against E. coli O157:H7 and S. aureus. All AER microemulsions showed no significant hemolytic activity. On the contrary, AET microemulsions showed hemolytic effect but those in concentrations of 8.0% (≈70%) and 5.0% (33%) showed the highest effect. In addition, AER microemulsions showed protective effect against free radicals in comparison with the AET microemulsions (p<0.05). On the other hand, the AET microemulsion at 8.0% showed antibacterial effect against E. coli O157:H7 and S. aureus, and the AER at 8.0% showed antibacterial effect against E. coli O157:H7. The limitation of this study was that nucleated cells were not used to observe the damage of the essential oils on nuclear material. However, the observed damage of erythrocyte’s membrane is depending on type and amount of used oil. Therefore, it can be concluded that the AER microemulsions showed better protective effect of erythrocytes, while AET microemulsions showed better antibacterial effect against the tested bacteria, although with toxic effect on the erythrocytes.

Authors:   , Anaya-Félix L. E.
Published: August 2021

Cerebral Palsy (CP) is a group of permanent pre, post and perinatal disorders of the motor and posture development due to non-progressive alterations in brain’s natural development caused by injuries in the Central Nervous System. Due to the importance of the daily use of the upper limb members, it’s important to consider more efficient ways to evaluate the performance in patients diagnosed with CP. One way to obtain an evaluation of the performance of the thoracic member is recording defined movements and calculating the smoothness, using an instrumented sorting block box. Our objective is to create a protocol of valuation for the upper member that is objective, efficient and that gives a quantitative feedback of the grade of the motor affectation of child with PC in a clinical environment.
Analysis of the absorption spectra of EBT2 and EBT3 radiochromic films
Authors:   , León-Marroquín E. Y.
Published: August 2021

To analyze the net absorption spectra of EBT2 and EBT3 radiochromic films to describe their influenceon the behavior of dose-response curves. The films were irradiated in a linear accelerator of 6 MV. The net absorption spectra were obtained with a UV / VIS spectrophotometer. Dose-response curves were obtained with a scanner, a He-Ne laser and a spectrophotometer. The absorption spectrum of the EBT2 shows three focused absorption bands that retain position and increase their intensity as a function of dose, however, this behavior is not observed in EBT3 films. The dose-response curve shows maximum sensitivity using the spectrophotometer, but does not show a defined behavior. Generation of new knowledge for the creation of new optical systems capable of amplifying the responsiveness of the films. Show the correlation between net absorption spectra and their influence on dose-response curves in three different optical systems. The behavior of absorption spectra combined with the behavior of the dose-response curves helps to discard the use of optical systems that do not guarantee a reliable clinical use.
Effect of EEG pre-processing on Independent Component Analysis: reduction of cochlear implant artifact in Auditory Evoked Potentials
Authors:   , Trejo Alcantara G.
Published: August 2021

Independent Component Analysis (ICA) is an algorithm used to remove artifacts from the EEG. However, there is little current literature about the impact of preprocessing stages of this signal on the performance of ICA. In this paper the effect of applying two different digital filters - lowpass and bandpass -, in a pre-processing step to ICA, was compared. This to remove the cochlear implant artifact from the Auditory Evoked Potentials. Recordings from 10 cochlear implant users were analyzed. In 5 of these records using the pre-lowpass filtering, the highest Signal Interference Ratio (SIR) was obtained; this index was used to assess the quality of ICA separation. The greatest effect of removing the cochlear implant artifact is noted in both T4 and T6 electrodes, which correspond to the area where the subjects have placed their implants (right temporal area).
