Published: May 2022

Diabetic Retinopathy (DR) is a common complication of diabetes mellitus, which causes lesions on the retina that effect vision. Many researchers have supported the ophthalmologists to diagnosis and classify the stage of the disease in the retinal fundus images using machine learning model. Machine learning models are less impressive for several staging diseases due to clinical grading. In order to develop a system capable of classifying the lesion grading images on disease pathology, a unique deep learning architecture named as discriminative Convolution Neural Network has been employed towards diagnosis of diabetic retinopathy through classification and progression prediction of lesion grading in fundus image of Retina. Initially Image Pre-processing has been carried out using wiener filter to remove the noise and Contrast limited adaptive histogram equalization for image enhancement. Pre-processed image has been processed using Oriented Fast and Rotated Brief for feature descriptors. It contains like Optic distance, Fovea, blood Vessel, Blot haemorrhages, Exudate number, exudates area, Macular Edema, Bifurcation, Shannon entrophy, Kapur Entropy and Renyis Entropy, LBP entropy, LBP energy and Microaneurysm. On these obtained features, feature reduction has to be carried out using principle component analysis to eliminate the irrelevant features before the onset of the process.

Authors: Pérez Diana Milena Callejas 
Published: May 2022

A educação emocional é entendida como um aspecto fundamental no desenvolvimento integral de todo ser humano, como afirma Bisquerra (2001), é um "processo contínuo e permanente que tem por objetivo melhorar o desenvolvimento emocional como um complemento indispensável ao desenvolvimento cognitivo, constituindo ambos os elementos essenciais do desenvolvimento da personalidade integral" (p.242). Este trabalho, que faz parte de uma pesquisa mais ampla sobre o fortalecimento da educação emocional para a prevenção de conflitos escolares em alunos da Escola Normal Superior Santiago de Tunja, em Tunja, Boyacá, visa identificar e analisar as referências bibliográficas e os artigos científicos que contribuem para o corpus documental ou o estado da arte da pesquisa. Para atingir o objetivo proposto, a metodologia utilizada foi a pesquisa qualitativa com foco na revisão documental e análise de artigos científicos de bases de dados como Scielo, Redalyc e Dialnet, através do instrumento de sistematização das informações do Resumo Analítico Especializado (RAE), elaborado no software Microsoft Excel. A implementação desta estratégia resultou na compilação, revisão e análise de 50 fontes bibliográficas internacionais, nacionais e regionais de 2003-2020. Da análise, emerge um campo de trabalho que está ligado à pesquisa, ou seja, o fortalecimento da educação emocional para a prevenção e resolução de conflitos escolares.

Equipment Reposition Optimization
Authors: Díaz Paola 
Published: May 2022

Las líneas marítimas necesitan un flujo continuo de equipos para mantener su servicio, competencia y operaciones en el sector logístico y cadena de suministro. El escenario ideal es lograr que cada contenedor que sea devuelto vacío al recinto portuario sea utilizado para una exportación en un corto periodo de tiempo. Los costos de reposicionamiento comienzan inmediatamente después que el contenedor ha sido retornado vacío al depósito o recinto portuario y aumentan progresivamente con el paso de los días en caso tal que el mismo no sea utilizado.
Las líneas marítimas asumen estos costos por un periodo de tiempo en base al contrato que tengan con la Terminal Portuaria, pero al final son los productores y consumidores finales quienes pagan el precio de esta sobre estadía que se traduce como una ineficiencia. El problema se genera cuando los analistas de precio cotizan el reposicionamiento del equipo según una regla previamente establecida en lugar de comprender lo que realmente está sucediendo, para así cotizar en base a cada situación particular. Por ende, existe la necesidad de identificar los desequilibrios de los equipos y planificar un reposicionamiento con costos y tiempos de tránsito mínimos. Todo lo anterior nos lleva a la estrategia comercial de tratar de obtener crédito por reposición basado en una exportación desde un recinto donde haya un exceso de equipo hacia uno donde haya una deficiencia y exista una alta demanda del mercado haciendo uso de la tarifa que paga el embarcador. Este estudio busca desarrollar estrategias de optimización de reposición de equipos para beneficiar a una línea marítima regional, con operaciones en Panamá, en aspectos tales como: mejor control de inventario y evitar contribuciones negativas al ganar más volumen de carga como consecuencia de ofrecer tarifas más competitivas.

Durante la década de 1970, Thomas L. Saaty desarrolló una metodología matemática que permite llegar a una toma de decisiones, denominada proceso de jerarquía analítica (AHP), que toma en consideración las alternativas más importantes que se deben manejar para responder o abordar un problema. También considera todos los atributos o criterios lógicos que permiten evaluar si la decisión a tomar es la más eficiente y correcta. Esta investigación aplicada aborda la metodología AHP para recomendar a una aerolínea regional las opciones que deben considerar implementar como beneficios que conformarán su propuesta de valor para sus clientes corporativos, con el fin de incrementar la satisfacción del cliente y revertir los valores de distribución desigual que presenta actualmente. El estudio también aborda conceptos basados ​​en la estrategia y la ventaja competitiva para el desarrollo de una propuesta integral de toma de decisiones basada en evidencia.

Authors: Pierre Doussoulin Jean , Salazar Molina Cristina 
Published: May 2022

This research evaluated the technical and economic feasibility of a biogas plant in the south of Chile to generate energy (WtE) for the plant’s own consumption, energy for sale to the country’s electricity grid and produce biofertilizer from municipal solid waste (MSW). In the town of Panguipulli, 26 tons of solid waste are produced daily, of which 12 tons correspond to household organic waste. These arrive directly to a landfill, wasting their potential to generate products and energy. To study the economic feasibility, an analysis was carried out on the investment, costs and income that make up the cash flow of the project evaluated at 15 years. The results gave an NPV of 214.099.637 CLP and an IRR of 15% at a real discount rate of 10%, with a payback period of 6 years. The research concluded that it is feasible to design a biogas plant that works from household organic waste in Panguipulli. This will contribute to the mitigation of climate change and will promote circular economy actions and the sustainable management of MSW in the south of Chile.
Development of a bead-based assay for detection of three banana-infecting viruses
Authors: Kuan Cheng-Ping , Tsai Chia-Hsin , Tseng Ching-Shan , Yang Tso-Chi 
Published: May 2022

Background
Banana bunchy top virus (BBTV), cucumber mosaic virus (CMV) and banana streak virus (BSV) are important banana viruses, there are possible infections frequently with several viruses in field. Since the viruses are readily trasmitted in vegetative propagules, which pose a threat to banana production in banana-growing areas.

Methods
A multiplex polymerase chain reaction (PCR) protocol combined with LiquiChip analysis to identify BSV, BBTV, and CMV, with consistent amplification of plant ubiquitin (UBQ), the banana plant messenger RNA used as a procedural control. Multiplex reverse transcription (RT)-PCR amplicons were extended by allele-specific primers, followed by hybridization with carboxylated microspheres containing unique fluorescent oligonucleotides, which were detected using the LiquiChip 200 workstation.

Results
In this study, we aimed to develop a rapid, sensitive, and simultaneous detection method for BSV, BBTV, and CMV using a bead-based multiplex assay that can be applied in routine diagnosis. We demonstrated that this detection system was extremely efficient and highly specialized for differentiating individual in a mixture of viruses while being ten times more sensitive than traditional RT-PCR. The development of this method makes it feasible to detect banana viruses in field collected leaf samples.
Exclusionary discipline practices and their relation to Chilean students' perception of school climate practices
Authors: López Verónica , Ortiz Sebastián , Ceardi Andrea , González Luis 
Published: May 2022

AbstractOne of the challenges of school climate policies has been to promote dialogical conflict resolution by reducing punitive practices and encouraging student participation. However, exclusionary punitive practices are still being used, and in Chile, they are considered acceptable forms of conflict resolution. In this study, we analyzed the association between students' reports of punitive and democratic school climate in a sample of 2459 eighth graders (mean age = 13.56, SD = 0.84) from 128 Chilean schools. Multilevel analyses showed that a higher perception of punitive practices and higher academic performance were associated with a higher perception of an inclusive, democratic, and peaceful school climate. The perception of a higher school‐level frequency of punishment was associated with a higher perception of an inclusive and democratic school climate. We discuss the implications of these findings for an authoritarian school culture.

ObjectiveThe study objective was to identify differences in gene expression between treatment responders (TRs) and treatment non‐responders (TNRs) diagnosed with juvenile dermatomyositis (JDM).MethodsGene expression analyses were performed using whole blood messenger RNA sequencing in patients with JDM (n = 17) and healthy controls (HCs; n = 10). Four analyses were performed (A1‐4) comparing differential gene expression and pathways analysis exploiting the timing of sample acquisition and the treatments received to perform these comparative analyses. Analyses were done at diagnosis and follow‐up, which averaged 7 months later in the cohort.ResultsAt diagnosis, the expression of 10 genes differed between TRs and TNRs. Hallmark and canonical pathway analysis revealed 11 and 60 pathways enriched in TRs and 3 and 21 pathways enriched in TNRs, respectively. Pathway enrichment at diagnosis in TRs was strongest in pathways involved in metabolism, complement activation, and cell signaling as mediated by IL‐8, p38/microtubule associated protein kinases (MAPK)/extracellular signal‐regulated kinases (ERK), Phosphatidylinositol 3 Kinase Gamma (PI3Kγ), and the B cell receptor. Follow‐up hallmark and canonical pathway analysis showed that 2 and 14 pathways were enriched in TRs, whereas 24 and 123 pathways were enriched in treatment TNRs, respectively. Prior treatment with glucocorticoids significantly altered expression of 13 genes in the analysis of subjects at diagnosis with JDM as compared with HCs.ConclusionNumerous genes and pathways differ between TRs and TNRs at diagnosis and follow‐up. Prior treatment with glucocorticoids prior to specimen acquisition had a small effect on the performed analyses.

Published: May 2022

AbstractHigh‐quality customized monolayer graphene structures are a prerequisite for various applications such as electronics, optoelectronics, and energy devices. Top‐down photolithography is the main method for graphene patterning, but it is greatly affected by complex manufacturing processes and residual photoresist. Recently, bottom‐up methods based on catalyst or precursor patterning have been developed. Although these methods can achieve high‐resolution graphene patterns, it is difficult to control the number of graphene layers and has a high defect density. Here, the authors propose a selective area reconstruction method for in‐situ growth of high‐quality monolayer graphene structures on copper substrates. The method utilizes selective oxidation and high‐temperature reduction technologies, which can effectively regulate the surface characteristics of the copper substrate, thereby precisely controlling the nucleation and growth behavior of the customized graphene structure. The feature size of the fabricated graphene structure is less than 1 µm and it has high monolayer coverage and extremely low defect density. The performance of the photoluminescence device and photodetector based on the customized monolayer graphene structure is characterized. The method provides a new approach for the direct growth of high‐quality, scalable, and high‐precision functional graphene structures, which is expected to have great potential in the optoelectronic applications.
Few‐Layered ReS2@CNTs as a High‐Performance Cathode for Aluminum‐Ion Batteries

Published: May 2022

AbstractWith a high theoretical specific capacity of 2978 mAh g−1, rechargeable aluminum‐ion batteries (AIBs) are considered as promising next‐generation energy storage devices with higher electrochemical performance. Nevertheless, the search for stable cathode materials with outstanding capacity and rate performance remains elusive. In current work, few‐layered ReS2 is in situ grown on carbon nanotubes (CNTs) to form the ReS2@CNTs composite. As ReS2 features a large interlayer spacing of ≈0.65 nm, the extremely weak interlayer coupling can effectively reduce the electrostatic repulsion between Al3+ ions and the cathode host, adequately accommodating large amounts of Al3+ ions without significant volume expansion. When it serves as the cathode in the AIB, ReS2@CNTs delivers a high discharge specific capacity of 396.3 mA h g−1 and Coulombic efficiencies of ≈100% both after 250 cycles at a low rate (200 mA g−1) and 10 000 cycles under a higher rate (1 A g−1). Theoretical simulations and ex situ grazing incidence angle X‐ray diffraction results reveal that Al3+ cations can be favorably and reversibly intercalated/deintercalated into the ReS2@CNTs during the discharge/charge process. This work provides new insights into AIB chemistry and paves the way for the development of high‐performance AIBs.

Published: May 2022

AbstractIn this article, a new method is proposed to quantificationally evaluate the effect of pore heterogeneity on the adsorption behavior of fluids in nanopores. First, the assumptions of furrowed, sinusoidal, and ravine pore surfaces are proposed to represent the heterogeneous nanopores in shale. Under the assumptions, a multicomponent potential theory of adsorption (MPTA) is coupled with Peng–Robinson equation of state (PR EOS) to model the adsorption behavior of hydrocarbons in nanopores. And, the geometrical and chemical heterogeneities in shale nanopores are, respectively, simulated by a spatial alteration and an amplitude deformation on potential energy. The fluid–fluid interaction is modeled by PR EOS, and the fluid‐pore wall surface interaction is simulated by a Steel 10‐4‐3 model for slit‐like nanopores and by a modified Lennard–Jones (LJ) 12‐6 model for cylindrical ones. Thereafter, the results of our theory are compared against the experimental data of shale rocks to validate its accuracy.
Close physical proximity on the job—An exposure matrix
Authors: Vergara Ximena P. , Gibb Kathryn 
Published: May 2022

AbstractBackgroundThe workplace is a setting for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) transmission via respiratory droplets and aerosols for those working in close proximity to others. Currently, limited methods exist for assessing SARS‐CoV‐2 exposure. Since occupation serves as a surrogate measure, job exposure matrices (JEMs) can be useful for population‐based exposure assessment for a portion of exposure.MethodsWe developed a JEM to assess physical proximity at work. Scores for questions related to frequency of face‐to‐face discussions, working closely with others, and working with a team were extracted from a US‐based, comprehensive source of descriptive occupational information (Occupational Information Network [O*NET]). We described score distributions using univariate analyses, devised thresholds, and assigned exposure levels for 968 O*NET occupations. Three exposure measures were constructed using combinations of O*NET data, with expert judgment, and accounting for telework. National and California employment estimates were used to assess the workforce proportions by proximity level and demographic characteristics.ResultsWe categorized 535 US Census occupations (2010) into four‐level ordinal exposure levels (not close to very close). Overall, an estimated 56% of the California workforce worked in very close proximity, which decreased to 46% when accounting for telework. The occupational groups working very close across all three measures were: healthcare support, healthcare practitioner, food preparation and serving, building and grounds cleaning and maintenance, and protective service occupations. Latinos and women were overrepresented within occupations working in very close physical proximity.ConclusionJEMs can inform SARS‐CoV‐2 exposure assessment for epidemiologic studies, assist in resource allocation, and inform prevention strategies.

Published: May 2022

AbstractBackgroundOrganic solvents have been suggested to increase the risk of breast cancer although the epidemiologic evidence is limited. This study explored the association between organic solvents and breast cancer.MethodsThis nested population‐based case‐control study comprised 845 women with primary breast cancer initially identified in the Danish Cancer Registry between 2000 and 2003, and 1500 controls matched on year of birth who were randomly selected from the Danish Civil Registration System. Information on occupational exposure to organic solvents, and specifically ethanol, as well as risk factors for breast cancer was collected through structured interviews.ResultsFor organic solvents, an increased risk was indicated for ever‐exposure (odds ratio = 3.20, 95% confidence interval: 2.27–4.52), however, no noteworthy risk patterns were detected when exploring duration of exposure and cumulative exposure. Ever‐exposure to organic solvents was associated with an increased risk of estrogen receptor negative and positive tumors as well as pre‐ and postmenopausal breast cancer. No associations were detected between occupational exposure to ethanol and breast cancer.ConclusionsThis study indicates a positive association between organic solvents and breast cancer.
