FORMAÇÃO DE PROFESSORES: ESCLARECIMENTO E AUTORREFLEXÃO PARA UMA EDUCAÇÃO EMANCIPATÓRIA COM BASE EM THEODOR ADORNO
Authors: Freitas Nidal Afif Obeid , Campos Luciana Maria Lunardi
Published: June 2021

Este artigo tem por objetivo apresentar contribuições epistemológicas do pensamento de Theodor Adorno para a reflexão sobre formação docente emancipatória a partir dos conceitos de esclarecimento e autorreflexão. Tendo a perspectiva dialética como referência para pensar a sociedade e suas contradições, bem como a formação do professor, pretende-se evidenciar que, apesar do desenvolvimento do capitalismo, um sistema apto a impedir as tentativas de transformações equitativas, há a possibilidade de desenvolvimento de uma atitude de autocrítica e de resistência que pode ser posta em ação pelos indivíduos por meio do esclarecimento e da autorreflexão. Formar o docente em uma proposta emancipatória requer a adoção de um projeto consistente que leve a superar a adaptação e consiga desvelar as contradições sociais, a fim de que o indivíduo possa transitar conscientemente no mundo, com o mundo e para a sua transformação.
AÇÕES AFIRMATIVAS COMO GARANTIA E DIREITO À EDUCAÇÃO DA POPULAÇÃO NEGRA NO BRASIL
Authors: Da Silva Parreira Gaia Ronan , Da Silva Vitória Alice , Aparecido Gonçalves Pereira João , Scorsolini-Comin Fabio
Published: June 2021

Análises acerca da história do Brasil evidenciam impasses aos direitos da população negra mesmo após a abolição da escravatura. A educação, direito fundamental de todo cidadão, é um dos exemplos nítidos dessa questão, e os dados estatísticos apontados ao longo do estudo comprovam a licitude desta afirmação. Assim, o presente estudo, de caráter teórico, buscou estabelecer um panorama geral, e devidamente atualizado, sobre as Políticas de Ação Afirmativa à Educação – direito fundamental – do negro no Brasil. A partir dos dados expostos neste ensaio crítico, é possível concluir que a igualdade social – garantia constitucional – só será possível quando houver a conscientização de que educação de qualidade não é mera oportunidade ou privilégio. As cotas compõem um direito fundamental aos negros e aos indígenas brasileiros não apenas devido à dívida histórica do Estado para com essas populações, mas porque o acesso à educação não deve ser apenas uma oportunidade ou fruto de uma meritocracia, e, sim, um direito do cidadão e dever do Estado. Enquanto houver a deturpação de direitos civis como a educação a uma parcela específica da sociedade, a democracia neste país há de ser interrogada.
Dlaczego dobra i dlaczego dyskusyjna jest książka Raewyn Connell o teorii społecznej?
Authors: Szmeja Maria
Published: June 2021

Praca Raewyn Connell dotyczy dominacji poglądów metropolitalnych w teorii społecznej. Jej książka Teoria z globalnego Południa wywołała spór wśród europejskich i amerykańskich socjologów. Zakwestionowanie genezy socjologii i jej drogi rozwoju, wskazanie na alternatywne źródła wiedzy o społeczeństwie stanowią główną myśl pracy. Niewątpliwie książka ma zalety i wady, a dyskusja socjologów nad utrzymaniem lub zmianą istniejącego paradygmatu nauk społecznych zaangażowała również polskich socjologów.

Authors: Fajriani Fajriani
Published: June 2021

The Self-Potential (SP) method was used to identify changes in the potential groundwater in the area of Gampong Lengkong, Langsa City. The data acquisition technique was carried out with a fixed base technique with a measurement count of four acquisition line. Research is conducted for two months that July and August are the same in order to monitor the changes in the SP value associated with the change of SP anomaly. Interpretation is done qualitatively and quantitatively. Qualitative interpretation through analysis maps of the isopotential contours compared between the first month and the second month of measurements in the field. The interpretation is quantitatively by assuming the source of the subsurface anomaly fix geometry models of cylinders or sphere is done by the inversion modeling using the Levenberg-Marquardt method. The results showed that there was a reduction in SP value in the second month, indicating the potential shortage of groundwater in the region. The decrease in groundwater potential is also shown in the inversion results where the result of the calculation of SP anomaly source parameters in the first month is estimated to be at 7.77 meters to 11.05 meters below the ground in the monthly measurements second.

Authors: Седова Л. Г. , Соколенко Д. А.
Published: June 2021

Модиолус курильский Modiolus kurilensis F. R. Bernard, 1983 (Mollusca, Bivalvia) — двустворчатый моллюск семейства Mytilidae; он встречается в заливе Петра Великого (Японское море) на мягких и твёрдых субстратах, зачастую совместно с мидией Грея Crenomytilus grayanus (Dunker, 1853), и является перспективным промысловым видом. Его добывают в качестве прилова при добыче C. grayanus. Цель работы — оценить ресурсы и состав поселений M. kurilensis в заливе Петра Великого. Исследования проводили в 2007–2018 гг. с применением стандартных водолазных гидробиологических методов, изучая глуби́ны до 20 м. Выполнено 2409 станций, модиолус обнаружен на 308 из них. Собранных моллюсков измеряли и взвешивали. В результате статистической и картографической обработки материала получены усреднённые данные о плотности и биомассе поселений M. kurilensis. Для изучения состава поселений модиолуса проанализировано 870 экз. Определяли следующие параметры: показатель оседания молоди (отношение численности молоди размером 1–30 мм (сеголетки, годовики) к числу взрослых особей с длиной раковины более 50 мм); показатель созревания (отношение численности молодых моллюсков пререпродуктивного возраста (35–50 мм) к числу взрослых особей с длиной раковины более 50 мм); пополнение промысловой части поселений (отношение рекрутов (95–100 мм) к числу особей промыслового размера с длиной раковины > 100 мм). Состояние популяции M. kurilensis в заливе Петра Великого стабильно: доля особей непромыслового размера в разных поселениях варьирует от 52 до 86 %, что свидетельствует об активном естественном воспроизводстве и регулярном пополнении бентосной части популяции на протяжении многих лет. Пополнение поселений оседающей молодью зависит от наличия пелагических личинок в планктоне, а их половозрелой части — от благоприятных условий для выживания молоди. Средние значения показателей оседания и созревания в поселениях M. kurilensis в заливе Петра Великого в 2007–2018 гг. составляли (0,18 ± 0,07) и (0,05 ± 0,01) соответственно. Ресурсы M. kurilensis оценены в 27,1 тыс. т, а промысловый запас — в 16,4 тыс. т. Ежегодное пополнение промысловой части поселений M. kurilensis в заливе Петра Великого возможно в объёме более 3 тыс. т. Среднее значение показателя пополнения промысловой части — (0,21 ± 0,03).
Classification and Evaluation on Shale Gas Reservoir for Wufeng-Longmaxi Formation in Chuannan Area, Sichuan Basin
Authors: Guo Jianlin , Jia Chengye , He Dongbo , Meng Fankun
Published: June 2021

Based on the comprehensive statistic and analysis on some representative geological and physical data, the classification criteria on net pay for shale gas reservoir of the Wufeng-Longmaxi formation in Shunan area, Sichuan Basin, are proposed, which include porosity (φ), gas saturation (Sg), density of rock (DEN), brittleness index (BI), and gas content (Vt). When the porosity, gas saturation, brittleness index, and gas content are larger than 3%, 30%, 40%, and 1 m3/t, respectively, and the density of rock is lower than 2.7 g/cm3, then this formation can be seen as the net pay. The application of two key parameters, gas content and brittleness index, could reflect the reservoir resource basis and fracability, respectively. The gas content has a positive correlation with porosity and total organic volume, and the brittleness index has a positive correlation with siliceous and carbonate content. According to the range of these two parameters, the net pay can be classified into three types. For type I, the gas content and brittleness index are larger than 4 m3/t and 50%, respectively. For type II, either the gas content or the brittleness index is lower than 4 m3/t and 50%. For type III, the gas content should be larger than 1 m3/t and lower than 4 m3/t, and the brittleness index is between 40% and 50%. The field application case indicates that the Wufeng formation and low member of the Longmaxi formation have good quality and mainly consist of type I and II formations. In addition, it is found that there is a positive correlation between the penetration ratio for type I formation and the testing production and estimate ultimate recovery (EUR). While this ratio is larger than 50%, the testing production rate and EUR will be over 15×104 m3/d and 8000×104 m3 with a probability of 92%, which meet the requirement of exploitation with reasonable economic benefits.

Published: June 2021

Background: Chronic Arsenic exposure causes skin manifestations and even cancer. However, the response varies widely among persons despite receiving similar cumulative exposure through their food or drinking water or both. These differentiations in manifestations may be due to polymorphic distribution of arsenic metabolizing genes among exposed people. Method: Polymorphism of GSTO1, GSTO2 and their frequency distribution may modify skin manifestations and development of arsenic induced cancer in exposed persons through food chain. Polymorphic variations of GSTO1 and GSTO2 have been studied on 112 subject including control. They were recruited from one of major arsenic affected district, Nadia of West Bengal, India, having high arsenic content in their food. Exposed subjects were categorized into three groups, i.e, with arsenical skin lesions and with out arsenical skin lesions and arsenic induced cancer. Control subjects were 33 in number. Concentration of arsenic in their urine, hair, drinking water, food, extent of clinical manifestations, GST O1and O2status was determined. DNMT1, 3A, and 3B were studied for their expression profile and analyzed with GSTO1 and O2 polymorphisms. Result: Genetic polymorphism of GSTO1 gene polymorphism is significantly associated with arsenic induced skin scores in skin lesion positive cases and arsenic induced cancer cases and also significant increase is seen in DNMT expression and MDA level in exposed cases with homozygous wild type variants. Total urinary arsenic decreases significantly in wild type GSTO1 genotype, although, GSTO2 polymorphism showed no statistically significant differences in skin manifestations, and DNMTs expression. Frequency of GSTO1 and O2 polymorphic variety showed prevalence of wild type homozygous in arsenic induced cancer cases.Conclusion: GSTO1 polymorphism shows significant association with DNMT expression profile in arsenic exposed people.

Authors: Wang Zhaofeng , Chen Qingqing
Published: June 2021

A better understanding on the spatial matching relationship between tourism urbanization and resources and environment carrying capacity is vital for the regional selection of the key eco-livable tourist cities in the Yellow River Basin. This paper addressed this research issue by evaluating and partitioning tourism urbanization level and resources and environment carrying capacity of the Yellow River Basin in 2005, 2011 and 2018, using GIS technology, spatial autocorrelation model and partition method. Empirical results suggest that (1) The tourism urbanization level of Shaanxi province maintains the leading position, while Shanxi province has great development potential. The high value areas of resources and environmental carrying capacity concentrated in Gansu, Inner Mongolia and Shandong provinces. (2) The spatial agglomeration degree of tourism urbanization level and resources and environment carrying capacity have been improved. (3) The resources and the environment carrying capacity exhibits a greater restrictive effect on the current high-level areas of tourism urbanization, and the spatial correspondence between them is weak.

With ongoing urbanization, traffic congestion and the air pollution it induces are worsening. Using a system dynamics approach, this study constructed a driving-restriction policy model to explore the effects of different stages of policy implementation on variables such as traffic congestion, emissions, and parking demand. Medium- and long-term dynamic simulation showed that the effect of the policy was obvious in the initial stage but gradually weakened in the medium term, leading to a “fading” effect on emission reduction and traffic-congestion alleviation; a “rebound” effect was even observed at the end of the simulation. Thus, the policy will not effectively reduce traffic congestion in the long term and will induce a new demand for car purchases, resulting in paradoxical effects, which will aggravate parking demand, congestion, and pollution. Yet, it was also found that introducing penalty policies and an air pollution charging fee could weaken the paradoxical effects and compensate for some defects of the policy. Such strategies could help reduce emissions, traffic congestion, parking demand, the number of illegal trips, and the overall number of vehicle trips. These findings can provide not only a theoretical basis for further research but also practical guidance for policy improvement.

Background: Indonesia, the largest archipelago globally with decentralized health system, is faced with a stagnant high maternal mortality ratio (MMR). The disparity factors among regions and inequities in access have deterred the local assessments in preventing similar maternal deaths. This study explored the challenges of district maternal death audit (MDA) committees to provide evidence-based recommendations for local adaptive practices in reducing maternal mortality.Methods: A qualitative study was conducted with four focus-group discussions in Central Java, Indonesia, between July and October 2019. Purposive sampling was used to select 7-8 members of each district audit committee. Data were analyzed using the thematic analysis approach. Triangulation was done by peer debriefing and reviewing audit documentation.Results: The district audit committees had significant challenges to develop appropriate recommendations and action plans, involving: 1) lack of information to facilitate an accurate review; 2) no explicit clinical standard available; 3) poor support from key hospital decision-makers, and 4) insufficient skills of district health officers to organize standard MDA. The district audit committees tended to associate maternal death in lower and higher-level health facilities (hospitals) with mismanagement and unavoidable cause, respectively. These unfavorable cultures discourage transparency and prevent continuing improvement, leading to failure in addressing maternal death's local avoidable factors. Conclusion: A productive MDA is required to provide an evidence-based recommendation. A strong partnership between the key hospital decision-makers and district health officers is needed for quality evidence-based policymaking and practice to prevent maternal death.

IntroductionThe years 2020 and 2021 were marked by the pandemic of SARS-CoV-2, a virus that infected 167 million more people, causing about 3.4 million deaths worldwide. And, because of this, the main global health agencies (WHO, governments, emergency services, hospitals and other health professionals), sought means of protection for workers on the front line to combat the pandemic. The Fire Brigades of Brazil, had the need to adopt new protocols of actions, which would mitigate the progress of the disease, justifying the importance of curbing the effects of the pandemic in their corporations and other victims of COVID-19.Case descriptionThe objective of this work is to propose the systematization of control and combating future pandemics, seeking to contribute with a model of assistance protocol that adapts to the needs of health institutions. The study is a literature review and is based on data collected through a questionnaire applied to the Brazilian Fire Departments in the 26 states and the Federal District.Discussion and evaluationWith the mapping of the actions carried out, it was possible to identify which actions were implemented, which involve the creation and development of new service protocols such as the use of specific PPE, care with the disposal of contaminated materials and behavioral changes, avoiding contamination. Within the mapping carried out in the corporations, it is possible to obtain relevant data in the fight against the coronavirus, such as (use of new PPE, exclusive vehicles, testing of personnel, infected firefighters, number of deaths, stress, change in work routines).ConclusionsWith the coronavirus pandemic, the Fire Brigade promoted an alignment between needs and decision making, through internal protocols of related actions, which were essential in the search to mitigate the impacts caused by the pandemic. Such actions serve as a model to be used in other work environments.

With the aim to prevent possible power plant malfunction due to the feedstock properties and suggest possible ash applications, feedstock samples and bottom and fly ash samples collected along more than a year in a 16 MW suspension-fired boiler power plant, fed mainly with pulverized exhausted olive cake (orujillo), were studied. A detailed characterization of fly and bottom ash has been done, as well as a seasonal evolution study. Altogether in order to find any trend on the ash composition changes and to study the relationship between ash (both fly and bottom fractions) and, on the one hand, the feedstock composition, and on the other hand, the troublesome deposit formation. A relationship between deposit growth and higher Cl and Na content in the feedstock has been noticed, showing the need for some control on these feedstock’s components. The high Cl and Na content is attributed to external contamination. Furthermore, the high Al content in the feedstock and the strong relationship between Al, Fe and Si (indicating a common origin) suggest some biomass soil contamination. However, no relationship was observed between troublesome deposit formation and the hypothesized biomass soil contamination.

Published: June 2021

Background: Using decision aid rules for diagnosis of acute myocardial infarction (AMI) is not common practice in our region. Elderly patients are often neglected in clinical trials, and the proper diagnostics of acute myocardial infarction in this group remains problematic. The objective of this study was to evaluate the accuracy and effectiveness of different strategies for the diagnosis of AMI in the elderly in real-life clinical practice. Methods: In a retrospective single-center study, we included patients older than 70 years presenting to the emergency department with chest pain as a dominant symptom. The performance of six decision aid rules (T-MACS, HEART, EDACS, TIMI, GRACE, and ADAPT) and solo troponin T strategy for diagnosing acute myocardial infarction was evaluated by calculating sensitivity, specificity, odds ratios, negative and positive predictive values.Results: A total of 250 patients, with a mean age of 78.5 years, were enrolled. Forty-eight patients (19.2%) had an acute myocardial infarction in a 30 day follow-up period. The sensitivity for ruling-out AMI was 100% for T-MACS, HEART, and ADAPT; 97.9% for EDACS, 93.8% for TIMI, and 81.3% for GRACE and solo TnT strategy. For ruling-in AMI, the specificity was 97.5% for T-MACS, 95% for TIMI, 83.2% for HEART, 81.7% for GRACE, and 46% for ADAPT. C-statistics were 0.52 for T-MACS, 0.51 for ADAPT, 0.47 for EDACS and GRACE, 0.46 for HEART and TIMI, and 0.33 for solo TnT strategy.Conclusion: T-MACS decision aid had the best performance with 100% sensitivity and 100% negative predictive value for rule-out AMI; 97.5% specificity and 64.3% positive predictive value for rule-in AMI. Other evaluated protocols were less accurate. Risk stratification of patients with suspected acute coronary syndrome based on decision aid rules can be used in real-life practice, even in the population of the elderly.

Background:Bladder cancer is one of the most common malignant tumors of the urinary system, and its incidence has been increasing in recent years. Ferroptosis is a recently discovered type of cell death, and some studies have suggested that it is closely associated with tumors. It can promote tumor apoptosis and also promote tumor development. Moreover, it has been reported that a correlation exists between long non-coding RNAs (lncRNAs) pairs and tumors. Herein, we developed an lncRNA pair signature associated with ferroptosis to predict the prognosis of bladder cancer. Methods: We combined the bladder cancer transcriptome data from the Cancer Genome Atlas (TCGA) database to identify ferroptosis-related lncRNA (FRlncRNA) pairs. Using univariate and multivariate Cox analyses and LASSO regression analysis, we identified a FRlncRNA pair signature. We subsequently assessed the predictive prognostic value of this signature and validated the results. Results: The signature included 18 lncRNA pairs and was highly accurate for clinical prediction in patients with bladder cancer. Univariate and multivariate Cox analyses and stratified analysis indicated that the model was an independent prognostic factor. Additionally, we detected a positive correlation between this signature and the tumor immune microenvironment. Conclusion: The FRlncRNA pair signature has good prognostic and clinical predictive value in patients with bladder cancer.
