Authors: Licar Ana Caroline Neres Castro 
Published: December 2020

Este artigo de natureza histórica objetiva analisar as relações de poder ”“ sob a perspectivafoucaultina ”“ no espaço escolar público primário da capital maranhense, na primeira década do séculoXX. Nessa análise, o objeto de estudo foi a polêmica sobre os livros da Escola-Modelo Benedito Leite,principalmente, a cartilha Escripta rudimentar (1908), envolvendo Barbosa de Godóis, autor dacartilha e diretor das escolas Normal e Modelo, e Antônio Lobo, inspetor da Instrução pública, em1911. Como pano de fundo para a polêmica, evidencia-se a disputa por poder ”“ entendido comodiscurso verdadeiro ”“ no campo pedagógico, travada entre Lobo e Godóis por meio de seus discursosmaterializados no jornal Diário do Maranhão. Os discursos materializados nos artigos da polêmicapublicados no jornal Diário do Maranhão revelaram uma intensa disputa por poder no campopedagógico da capital maranhense, que tinha como objeto de desejo o discurso legá­timo.

Authors: Rodrigues Renata Cardoso Belleboni 
Published: December 2020

História e Literatura não podem e nem devem ser apenas vistas como disciplinas auxiliares.Dependendo do contexto a ser analisado, e mesmo no contexto de algumas teorias historiográficas, sãocategorias justapostas. Em relação aos estudos sobre o mundo grego antigo, as fontes literárias sãodocumentos imprescindá­veis para a construção do discurso do helenista. Para determinados temas aserem analisados, por vezes, o estudioso conta apenas com textos escritos. No caso dos estudosrelativos á górgona Medusa, há inúmeras fontes de cultura material que a retratam. Mas a culturaescrita foi a responsável por cristalizar os poderes deste monstro no pensamento do homem antigo e docontemporá¢neo. O objetivo deste artigo é apresentar algumas passagens da literatura antiga em queMedusa é descrita e analisar como estas fontes auxiliaram no estabelecimento dela no campo do medo.

A MARCHA DOS CARNEIROS: estratégias de ascensão e mobilidade social da famá­lia Carneiro nas Capitanias do Norte, séculos XVII e XVIII
Authors: Morais Ana Lunara da Silva 
Published: December 2020

A famá­lia Carneiro é original de Portugal, tendo chegado á capitania de Pernambuco, na América portuguesa, antes da invasão holandesa. A famá­lia destacou-se por ocupar cargos administrativos e militares, sobretudo, em Pernambuco, e por possuir engenhos. Além disso, a famá­lia contava com uma ampla rede social, estabelecida por meio de casamentos e de amizades. Contudo, para estabelecer-se neste privilegiado espaço social da capitania de Pernambuco e suas anexas, a famá­lia Carneiro passou por perá­odos conturbados, de insegurança polá­tica e econômica, como ocorreu na Guerra dos Mascates (1710-1711). A famá­lia valeu-se de estratégias para ascender socialmente e manter-se no poder, tendo atuando também nas capitanias do Ceará e Rio Grande para diversificar suas atuações polá­ticas e econômicas, e estabelecer novas redes sociais.

Published: December 2020

Coral platy fish has a unique reproduction due to ovoviviparous (live-bearer) reproduction. The large scale production of coral platy fish has several constraints due to the inconsistent seed birth period, which causes variations in the fry size. This makes it difficult for ornamental fish cultivators for production process efficiency and market criteria fulfillment that demands size uniformity. This study aimed to synchronize the broodstock birth period of coral platy fish by testing the hormone oxytocin and prostaglandin-2 α (PGF2α) through immersion methods with different durations. This study used a factorial randomized design with 21 treatments and 3 replications for each hormone type. The PGF2α hormone doses used were 0; 0.01; 0.1 and 1 mL/L, while the oxytocin hormone doses used were 0; 0.1; 0.2; 0.4 mL/L with immersion duration of 4, 8, and 12 hours, respectively. The results showed that the treatment dose of 1 mL/LPGF2α with 12 hour duration had a significant effect (p <0.05) compared to other treatments, the immersion group with 12 hour duration obtained a significant difference to the length of other treatments both at the percentage of broodstock giving birth and number of seeds. The hormone treatment had no significant effect on broodstock and seed survival (p> 0.05).

ABSTRAK
Ikan plati koral memiliki reproduksi yang unik karena bereproduksi secara ovovivipar (livebearer). Produksi ikan plati koral dalam skala besar dihadapkan kendala akibat waktu kelahiran anak yang tidak serentak yang menyebabkan keberagaman ukuran anak ikan plati koral. Hal ini menyulitkan para pembudidaya ikan hias untuk efisiensi proses produksi dan memenuhi kriteria pasar yang menuntut keseragaman ukuran. Penelitian ini bertujuan untuk menyeragamkan waktu kelahiran anak induk ikan plati koral dengan uji coba pemberian hormon oksitosin dan prostaglandin-2 α (PGF2α) melalui metode perendaman dengan durasi waktu yang berbeda. Penelitian ini menggunakan rancangan acak faktorial dengan 21 perlakuan dengan 3 kali ulangan untuk masing-masing jenis hormon. Dosis hormon PGF2α yang diuji adalah 0; 0,01; 0,1 dan 1 mL/L, sedangkan dosis hormon oksitosin yang digunakan adalah 0; 0.1; 0.2; 0.4 mL/L dengan masing-masing lama perendaman 4, 8, dan 12 jam. Hasil yang diperoleh menunjukkan bahwa perlakuan dosis 1 mL/L PGF2α dengan lama waktu perendaman 12 jam memberikan pengaruh yang nyata (p <0.05) dibandingkan dengan perlakuan lainnya, kelompok perendaman dengan durasi 12 jam memberikan perbedaan yang nyata terhadap lama perlakuan lain baik pada parameter persetasi induk melahirkan dan jumlah anak yang dilahirkan. Perlakuan hormon tidak memberikan pengaruh yang nyata terhadap kelangsungan hidup induk dan anak yang dilahirkan (p >0.05).

THE FUTURE OF MORAL THEORIES: REFLECTING ON TORBJÖRN TÄNNSJÖ’S BOOK “SETTING HEALTH-CARE PRIORITIES”
Authors: HUBENKO HANNA , BOICHENKO NATALIIA 
Published: December 2020

Torbjörn Tännsjö’s monograph “Setting Health-Care Priorities” clearly demonstrates its position in finest details involving case studies. It seems to be an especially valuable assistance, not least for study purposes, for those who are interested in a comprehensive review of plausible moral theories and the practice of fair resource distribution in the field of healthcare.
The author’s approach suggests engagement of the most applicable moral theories attempting to solve the important problem of sharing scarce and deficit resources in the healthcare. The book doesn’t aim for developing a single correct and effective moral theory for fair resource sharing, it rather discusses reaching a consensus regarding distribution decisions based on thoroughly reviewed theories.
The appeal to Population Ethics in the present paper emphasizes the difference between patient-centered approach in the situation of limited medical resources and distribution of resources among the population in general. The book represents author’s views towards the open problems in bioethics: prolongation of life of terminal patients; “right-to-die” (euthanasia); moral side of the assisted reproductive technologies; futile medical treatment; attitude towards abortion, etc.

Published: December 2020

Abstract
Background Heart rhythm complexity, a measure of heart rate dynamics and a risk predictor in various clinical diseases, has not been systematically studied in patients with end-stage renal disease. The aim of this study is to investigate the heart rhythm complexity and its prognostic value for mortality in end-stage renal disease patients undergoing hemodialysis.Methods To assess heart rhythm complexity and conventional heart rate variability measures, 4-hour continuous electrocardiography for a retrospective cohort of 202 ostensibly healthy control subjects and 51 hemodialysis patients with end-stage renal disease were analyzed. Heart rhythm complexity was quantified by the complexity index from the measurement of the multiscale entropy profile.Results During a follow-up of 13 months, 8 people died in the patient group. Values of either traditional heart rate variability measurements or complexity indices were found significantly lower in patients than those in healthy controls. In addition, the complexity indices (Area 1-5, Area 6-15 and Area 6-20) in the mortality group were significantly lower than those in the survival group, while there were no significant differences in traditional heart rate variability parameters between the two groups. In receiver operating characteristic curve analysis, Area 6-20 (AUC = 0.895, p<0.001) showed the strongest predictive power between mortality and survival groups. Conclusion The results suggest that heart rhythm complexity is impaired for patients with end-stage renal disease. Furthermore, the complexity index of heart rate variability quantified by multiscale entropy may be a powerful independent predictor of mortality in end-stage renal disease patients undergoing hemodialysis.

Published: December 2020

Abstract
Objective: This study aims to determine how randomly splitting a dataset into training and test sets affects the estimated performance of a machine learning model under different conditions, using real-world brain tumor radiomics data.Materials and Methods: We conducted two classification tasks of different difficulty levels with magnetic resonance imaging (MRI) radiomics features: (1) “Simple” task, glioblastomas [n=109] vs. brain metastasis [n=58] and (2) “difficult” task, low- [n=163] vs. high-grade [n=95] meningiomas. Additionally, two undersampled datasets were created by randomly sampling 50% from these datasets. We performed random training-test set splitting for each dataset repeatedly to create 1,000 different training and test set pairs. For each dataset pair, the least absolute shrinkage and selection operator model was trained by five-fold cross-validation (CV) or nested CV with or without repetitions in the training set and tested with the test set, using the area under the curve (AUC) as an evaluation metric.Results: The AUCs in CV and testing varied widely based on data composition, especially with the undersampled datasets and the difficult task. The mean (±standard deviation) AUC difference between CV and testing was 0.029 (±0.022) for the simple task without undersampling and 0.108 (±0.079) for the difficult task with undersampling. In a training-test set pair, the AUC was high in CV but much lower in testing (0.840 and 0.650, respectively); in another dataset pair with the same task, however, the AUC was low in CV but much higher in testing (0.702 and 0.836, respectively). None of the CV methods helped overcome this issue.Conclusions: Machine learning after a single random training-test set split may lead to unreliable results in radiomics studies, especially when the sample size is small.

Published: December 2020

Abstract
Background: Gastric cancer is a fatal gastrointestinal cancer with high morbidity and poor prognosis. The dismal 5-year survival rate urges reliable biomarkers to assess and improve prognosis of gastric cancer. Distinguishing driver mutations that were required for the cancer phenotype from passenger ones poses a formidable challenge for cancer genomics. Methods: We integrated the multi-omics data of 293 primary gastric cancer patients from The Cancer Genome Atlas (TCGA) projects to identify key driver genes by establishing the prognosis model of the patients. The combination of copy number alteration and somatic mutation analysis helped us to comprehensively reveal molecular markers of genomic variation. Integrating the transcription level of genes provides a unique perspective for us to discover dysregulated factors in transcriptional regulation. Results: The results, we identified 31 molecular markers of genomic variation comprehensively. For instance, the copy number alteration of WASHC5 (also known as KIAA0196) frequently recurrence in gastric cancer patients, which cannot be discovered using traditional methods based on significant mutations. Further, we revealed several dysregulatory factors played a "hubs" regulatory role in the process of biological metabolism based on dysregulatory networks. Cancer hallmark and functional enrichment analysis showed that these key driver genes (KD genes) played a vital role in regulating programmed cell death. The drug response pattern and transcriptional signatures of KD genes reflected its clinical application value. Conclusions: These findings indicated that the KD genes could serve as novel prognostic biomarkers for further research on the pathogenesis of gastric cancers, while elucidating a multidimensional and comprehensive genomic landscape and highlighting the molecular complexity.

Abstract
Calcaneal quantitative ultrasonography (QUS) is a useful prescreening tool for osteoporosis, but the advantages of QUS and dual-energy X-ray absorptiometry (DXA) remain unclear. We evaluated the correlation between QUS and DXA in a Taiwanese population. A total of 772 patients were enrolled and demographic data were recorded with the QUS and DXA T-score over the hip and spine. The correlation coefficient of QUS with the DXA-hip was 0.171. For DXA-spine, it was 0.135 overall, 0.237 in females, and 0.255 in males. The logistic regression model using DXA-spine as a dependent variable was established, and the classification table showed 66.2% accuracy. ROC analyses with Youden’s Index revealed the optimal cut-off point of QUS for predicting osteoporosis to be 2.72. This study showed a meaningful correlation between QUS and DXA in a Taiwanese population. Thus, it is important to pre-screen for osteoporosis with calcaneus QUS.

Abstract
Here, we report a facile synthesis of β-SnWO4 nanoparticles via microwave heat treatment using SnCl2 and H2WO4, in the presence of tamarind seed powder. X-ray diffraction analysis confirmed the crystalline nature, revealing a cubic structure of β-SnWO4 nanoparticles. Morphological features were visualized using a scanning electron microscope which exhibited homogenously distributed clusters of nanoparticles which were further confirmed using transmission electron microscope. The micrographs also displayed some porosity. Energy dispersive X-ray spectroscopy confirmed the elemental contents such as tin, oxygen and tungsten in the same stoichiometric ratio as expected by the respective empirical formula. High-resolution transmission electron microscope was used to find the d-spacing which was ultimately used to analyze the structural parameters. The spectrum obtained using Fourier transform infrared spectroscopy illuminates different stretching vibrations. Additionally, Barrett-Joyner-Halenda analysis was carried out to investigate N2 adsorption-desorption isotherm as well as to govern the pore size distribution. Cyclic voltammetry measurements were implemented to analyze the ongoing electrode reactions throughout the charge/discharge for β-SnWO4 nanostructures. The galvanometric charge/discharge curves for β-SnWO4 have also been discussed. A high specific capacitance (600 mAhg-1 at 0.1 C) and excellent columbic efficiency (~100%) was achieved.
