A geração de resíduos sólidos e sua disposição final ambientalmente correta têm sido alguns dos maiores desafios enfrentados atualmente no mundo e tem levado a criação de novas políticas públicas para melhorar a gestão e o gerenciamento destes resíduos. No Brasil se destaca o Decreto nº 5.940/2006, que estabelece a implantação da Coleta Seletiva Solidária (CSS) nas instituições públicas federais. Na Cidade Universitária Prof. José da Silveira Netto – Universidade Federal do Pará (UFPA), a CSS é de responsabilidade da Prefeitura Multicampi, que encaminha os materiais recicláveis recolhidos dos Locais de Entrega Voluntária (LEV) da Instituição para associações e cooperativas de catadores de materiais recicláveis da Região Metropolitana de Belém (RMB). O objetivo deste estudo foi avaliar quali-quantitativamente os materiais recicláveis constantes nos LEV da UFPA em três períodos, 2015, 2018 e 2019; analisar os resultados de ações de educação ambiental desenvolvidas nesse período; e estimar o valor bruto com a sua possível comercialização. Os resultados revelaram que a parcela de papel/papelão foi a mais significativa em termos de quantidade em relação aos demais materiais recicláveis.  O valor bruto estimado para a comercialização de três categorias de material reciclável (papel/papelão, plástico e metal), pelas associações e cooperativas em 2019, foi de quase R$ 30,000.00 (trinta mil reais).
Healthcare Monitoring System for Remote Areas
Authors: Bhati Nirbhay
Published: January 2023

Abstract: Doctors now place a high importance on ongoing patient health monitoring since it gives them the chance to save a patient's life. So, the primary objective is to develop a patient monitoring system that can monitor a patient's various physiological data when they are in a remote location and provide the doctor with this information in real time. The information is made public online so that any doctor in the globe can access it. The necessity for a patient to visit the doctor is lessened via remote patient monitoring. The Raspberry Pi employed here is not only a sensor node but also a CPU, and IOT plays a significant part in this complete system by delivering several apps and services. This data can be sensed, gathered, and published online by an intelligent gadget. The paper suggests a general health monitoring system utilising a neural network-based HDPS (Heart Disease Prediction System). The HDPS system forecasts a patient's risk of developing heart disease. The technique uses medical parameters like sex, blood pressure, age, height, and weight for prediction. as an improvement over the work done in this area up until now.

Authors: Nacor Andrea
Published: January 2023

Abstract: This study endeavored to determine work competence and job satisfaction of non-teaching personnel at Taguig City University and to formulate a proposed training program. A total of one hundred twenty-one (121) non-teaching staffs as respondents was drawn using purposive sampling technique. It employed descriptive method of research with emphasis on survey method using a researcher-made instrument. Further, it sought to answer the questions on demographic profile, work competence, and level of job satisfaction. The frequencies, percentages, weighted means, ANOVA, and chi-square were the statistical measures utilized. Results revealed that there was only a slight difference as to their sex due to very close interval. Half of the respondents are college graduate and most of them have a casual employment status with the range of 1-3 years in service. The study also found out that work competence level of non-teaching personnel was competent when it comes to oral, written communication and information communication technology. Also, they are highly competent when it comes to work ethics. On the other hand, job satisfactions of non-teaching personnel are highly satisfied in supervision, nature of work, interpersonal relationship and commitment. Furthermore, results showed that age affects the work competence level in terms of information and communication technology, work ethics and written communication while the civil status affects their work competence level in oral communication, written communication and information and communication technology. However, level of work competence in terms of information and communication technology, oral communication, written communication and work ethics do not depend on their sex. Also, their level of work competence in terms of oral communication, information and communication technology, work ethics and written communication depends on their educational attainment. Moreover, length of service does not affect their work competence level in terms of written communication, information and information technology and work ethics. But, the work competence in oral and written communication depends on their employment status and among the seven variables on job satisfaction, work competence does not depend on salary.

Published: January 2023

Objective: This study aimed to find new strategies for the prevention of bacterial biofilms and investigate the effect of some plant extracts on the biofilm formation by certain pathogenic bacterial strains in-vitro.

Methods: Fourteen different biofilm forming bacterial isolates were collected   and their biofilm were quantitatively measured under different temperature, pH and growth medium using Crystal violet staining method.  Exopolysaccharides (EPS) produced by the isolates were estimated and a comparison between the tested isolates was made. The effect of some plant extracts on bacterial growth, biofilm formation and exopolysaccharide quantity was determined.

Results: The two isolates, Listeria monocytogenes (ATCC13932) and Klebsiella pneumoniae (ATCC700613) were among the most active biofilm forming bacterial isolates.  The optimum temperature, pH and media for EPS production and biofilm formation were determined. The effect of some plant extracts of Cranberry; Pomegranate peel and, Arak on growth and formation of biofilm and EPS were recorded. Moreover, minimum inhibition concentration of each plant extract was performed.

Conclusion: EPS quantity produced from the tested isolates depends on some effective factors such temperature, media contents and pH. Aqueous-Cranberry, aqueous-Pomegranate Peel and methanolic-Arak extracts have antibacterial and antibiofilm activities on L. monocytogenes and K.  pneumonia. Thus, application of new natural approaches for inhibiting bacterial biofilm is important to prevent persistent and recurrent biofilm related infections.

The bioclimatic performance of buildings under climate change scenarios has been extensively studied from a thermo-energy perspective but hardly studied at all from the perspective of indoor daylight sufficiency. This shortcoming is related to the invariability of radiation data in the available weather files of future scenarios. This research proposes identifying the impacts that the variability of radiation data in weather files of future scenarios would have on daylight sufficiency in indoor spaces. The methodology includes the adaptation of available weather files and the running of daylight simulations for hypothetical workspaces located in Medellín, Colombia. The results show differences in the Spatial Daylight Autonomy – SDA metric of up to 18% in different future scenarios. In conclusion, the need is outlined to refine predictions of outdoor daylight availability that allow improving daylight performance evaluations under climate change scenarios.

Authors: Ávila-López Luis Alfredo , Zhen Mengxue , Zayas-Márquez Carolina
Published: January 2023

Many studies confirm the impact of financial development on the macro economy, but systematic studies of the impact of financial development on corporate exports is still lacking. Based on the quasi-natural experiment established by city commercial banks, this paper uses micro-data of Chinese industrial enterprises from 1998 to 2013 and adopts a double difference method to test the impact of the development of local financial institutions on corporate exports. The results show that the establishment of city commercial banks has significantly increased the export participation rate and total export volume of manufacturing enterprises in the city where they are located; comparatively speaking, its impact on the export expansion margin of industrial enterprises exceeds the intensive margin. At the same time, the study also found that the above-mentioned influences exist in both long-term and short-term, and in enterprises of different sizes and attributes. These findings provide new evidence for understanding the relationship between local financial development and corporate exports.

Authors: Etsay Haftu , Oniki Shunji , Berhe Melaku , Negash Teklay
Published: January 2023

Soil erosion and the consequent reduction in crop productivity pose a
critical challenge to enhance well-being and ensure food security of
rural people. As such, soil conservation practices have a paramount
importance to address crop productivity problems and restore the
degraded lands. This study explores the factors that affect farm
households’ decisions to the intensity of adoption of soil conservation
structures based on cross sectional data collected from 840 randomly
selected farm households in the Tigray region of Ethiopia. The study
finds that households with larger asset holdings tend to intensify the
use of soil conservation structures. Likewise, croplands that are
operated by households who participated in labor sharing and training
activities are treated with significantly denser conservation
structures. Moreover, farmers who have feeling of long-term tenure
security are more likely to invest in costly and durable conservation
structure such as stone bund. It further affirms that farmers are more
likely to intensify soil conservation structures if their holdings are
located at relatively steeper slope, are relatively more fertile, and
are closer to their residence. The results underscore the need for a
policy aimed at enhancing the capacity of farmers in terms of material
wealth and knowledge to enable them allocate significant portion of
their labor force for soil conservation on croplands.

Authors: Begum Farida , Hussain Fozia , Alam Muneer , 2 Bajracharya
Published: January 2023

Terrestrial life forms rely on productive soils to provide a medium for
plant growth and meet most of their nutrition needs. The aim of this
study was to determine the variation in soil organic carbon stocks
(SOCS), micro-arthropod communities, and physicochemical properties
under different crop cover in Oshikhandas valley, Karakoram Range,
Pakistan. Soil samples were collected from three depths under three
different crop cover types, i.e., alfalfa, wheat and potato. Standard
methods were used to analyze selected soil quality parameters and SOC.
Berlese-Tullgren funnel method was used for the extraction of soil
microarthropods. ANOVA results showed that physicochemical parameters
were non-significantly variable between different crops. At different
soil depths, bulk density (BD), pH, soil organic carbon (SOC), and SOCS
were highly significantly (p<0.001) different, while moisture
and electrical conductivity (EC) were non-significant. The highest value
of SOCS was found under alfalfa (16.2Mg/ha) followed by potato
(14.4Mg/ha), while it was lowest in wheat (12.2Mg/ha). Overall soil
texture was silty clay loam and the soil was alkaline (pH 8.2). A total
of 260 micro-arthropods were extracted and soil biological quality index
(QBS-ar) was calculated. The predominant species were mites (61%) and
Coleoptera (11%). The mean QBS index was highest in wheat (61.33)
followed by alfalfa (55.66), and lowest in potato (43.66). The soil
quality of the study area belonged to class 5 for wheat and 4 for
Alfalfa and potato, which indicated good soil quality class. The highest
population of micro-arthropod communities was seen in alfalfa (38%),
followed by wheat (36%) and lowest in potato (26%). According to the
results of the study, alfalfa is a good crop for improving soil
biological health and acting as a carbon sink, so farmers should be
encouraged to grow it for the long-term management of mountain
agro-ecosystems.

Calcium Carbonate as a Functional Filler in Polyamide 12 – Manipulation of the thermal and mechanical properties
Authors:   , Ippolito Fabio M.
Published: January 2023

Controlling and adjusting the thermal response properties of a polymeric compound is a key driver for improving its usability for an additive manufacturing process such as selective laser sintering, optimising the final part density as well as hardness. Adding mineral fillers to polymers was originally aimed at cost reduction. However, fillers are often used to fulfil a functional role, such as improved thermal or mechanical properties of the polymer composite. The influence of particle size distribution, filler morphology and filler amount of calcium carbonate as a mineral functional filler particle on the thermal properties in a compression-moulded polyamide 12 matrix was investigated. The possibility to combine precisely defined particle size distributions, thereby combining the benefits which each particle size range within the chosen material size distribution contributes to the matrix, was evaluated. The loss of ductility, occurring as a common downside of the introduction of a non-flexing mineral filler, has been investigated. The effect of an optimised coupling agent on the mechanical properties of a compression-moulded compound, containing polyamide 12 filled with surface modified calcium carbonate was also determined. Mineral filler modifier, namely 6- -caprolactam, L-arginine and glutamic acid, were chosen to investigate their coupling effect. The melt flowability at 190°C, the melting speed, melting and crystallisation point, degradation temperature, crystallisation time at 170 and 172°C, as well as the elongation at break were analysed. The melt properties of a polyamide 12 matrix show a significant dependency on the filler volume-based particle size. The finer and the narrower the particle size distribution of the calcium carbonate particles in the polymer matrix become, the less influence the filler has on the melting properties, influencing the melt flow less significantly than the same surface amount of broad size distribution coarse calcium carbonate filler particles. However, due to increased nucleation, the crystallisation behaviour on cooling showed a markedly more rapid onset in the case of fine sub-micrometre filler particle size. The overall thermal and flow properties can be optimised, by adjusting the morphology and particle size distribution of a coarse and fine calcium carbonate filler, blended in an optimised functional filler ratio. With an optimised surface modifying agent and/or filler morphology, the tensile strength as well as elongation at break can be improved in comparison with uncoated filler implementation, such that up to 60% of the loss of ductility and toughness of a final part when using an untreated filler could be regained using the correct amount of an optimised surface modifier. The improvements were demonstrated with a twin-screw extruded compound, indicating the potential for the usage of a functional filler within a polymer matrix as an optimised composite for additive manufacturing.
AEROPLAS – AERONAUTICAL PARTS DEVELOPMENT THROUGH LOW-COST TECHNOLOGIES
Authors: Pintos S.
Published: January 2023

The future of the aeronautical sector is oriented towards manufacturing lighter and more profitable structures and components, using more ecological materials and technologies, that allow reducing costs, weight and fuel consumption, with shorter manufacturing cycles, while increasing energy efficiency manufacturing. AEROPLAS project arises in this context, with the aim of contributing to the advanced manufacturing process of thermoplastic composites using low-cost technologies for the aeronautical industry. This study focuses on the replacement of aeronautical parts currently manufactured in thermosetting composite by thermoplastic ones, in two real components: cover panel and access door of the ventral fairing of A350, using two materials of different quality: LM-PAEK/CF semipreg (TenCate Cetex® TC1225) and PC/CF prepreg (ePreg245CHT/PC40). Through design and calculation, the stacking and part thicknesses necessary to cover the structural requirements of both components have been obtained, based on the data acquired from the characterization of the base materials. Two manufacturing processes have been studied and compared to obtain the new parts, selecting thermoforming and stamping as the most promising. Finally, the characterization of the pieces obtained has been carried out by means of non-destructive tests (visual inspection, ultrasonic verification, dimensional inspection using laser tracker) and destructive tests (pull-out strength on riveted joints [AITM1-0066], bearing strength [AITM1-0009], laminate tensile strength [AITM1-0007], fastened joints strength [AITM1-0067]).

Published: January 2023

The Covid-19 infection challenges medical staff to make rapid diagnoses of patients. In just a few days, the Covid-19 virus infection could affect the performance of the lungs. On the other hand, semantic segmentation using the Convolutional Neural Network (CNN) on Lung CT-scan images had attracted the attention of researchers for several years, even before the Covid-19 pandemic. Ground Glass Opacity (GGO), in the form of white patches caused by Covid-19 infection, is detected inside the patient’s lung area and occasionally at the edge of the lung, but no research has specifically paid attention to the edges of the lungs. This study proposes to display a 3D visualization of the lung surface of Covid-19 patients based on CT-scan image segmentation using U-Net architecture with a training dataset from typical lung images. Then the resulting CNN model is used to segment the lungs of Covid-19 patients. The segmentation results are selected as some slices to be reconstructed into a 3D lung shape and displayed in 3D animation. Visualizing the results of this segmentation can help medical staff diagnose the lungs of Covid-19 patients, especially on the surface of the lungs of patients with GGO at the edges. From the lung segmentation experiment results on ten patients in the Zenodo dataset, we have a Mean-IoU score = of 76.86%, while the visualization results show that 7 out of 10 patients (70%) have eroded lung surfaces. It can be seen clearly through 3D visualization.

Published: January 2023

Stock exchange trading has been utilized to gain profit by constantly buying and selling best-performing stocks in a short term. Deep knowledge, time dedication, and experience are essential for optimizing profit if stock price fluctuations are analyzed manually. This research proposes a new trading prediction system that has the ability to automatically predict the accurate time for buying and selling stock using a combination of technical analysis and support vector machine (SVM). Technical analysis is used to analyze stock price fluctuation based on historical data by utilizing technical indicators such as moving average, Bollinger bands, relative strength index, stochastic oscillator, and Aroon oscillator. SVM maps inputs into higher dimensional spaces using non-linear kernel functions, making it suitable for various technical indicators implementation as inputs in stock trading prediction. Experimentation on five Indonesian stocks reveals that the combination of technical analysis and support vector machine is best suited for continuously fluctuated stocks, with the highest accuracy of 77.8%.

Problem Structuring and Strategic Sorting Model for Financial Organizations
Authors: Schotten Paulo César , Morais Danielle Costa
Published: January 2023

Organizations adopt specific decision-making models that do not consider the intrinsic strategic aspects of the process, such as culture, target audience, decision-makers, organizational environment, and strategic goals. This article aims to present a group decision model that links the structuring of the problem to strategic organizational goals to work with the uncertainties of the process, helping decision-makers search for information and direct decision-making, allowing actors a broad and systemic vision linked to organizational goals. This model was developed for application in credit analysis and granting in financial organizations. The study is proven by the possibility of applying organizational strategy to the decision process using a problem-structuring model and the multi-criteria decision model. The model ensures that the paths reflect the corporate reality, and the vision regarding decision problems adopted serves the process, classifying the decision into answers representing the decision-maker's perception following the strategic aspects.

Published: January 2023

Objetivo: O objetivo da pesquisa foi analisar a relação entre a orientação empreendedora e o desempenho organizacional sob a influência da incerteza ambiental, em pet shops.
Método: Para alcançar o objetivo foi desenvolvida uma pesquisa quantitativa, com o uso da técnica survey. A amostra esteve composta por 112 pet shops de cidades de Santa Catarina. O estudo teve abordagem quantitativa, com caráter descritivo-correlacional. A análise de dados com uso das seguintes técnicas: análise fatorial exploratória (AFE), análise de variância (Anova), de correlação e de regressão múltipla.
Originalidade/Relevância: A originalidade e relevância do artigo estão, por um lado, na consecução de novas evidências empíricas a respeito das relações entre os construtos propostos. Por outro, na proposição de articulações teóricas ainda parcialmente respondidas em estudos empíricos para a realidade brasileira.
Resultados: Os resultados evidenciaram que as correlações entre orientação empreendedora e desempenho, mensurado pelos escores fatoriais, foram positivas e significantes. As regressões para o desempenho utilizando as dimensões da orientação empreendedora e o ambiente, medido pela soma das médias da percepção de intensidade e frequência das mudanças, indicaram que ele influencia de modo positivo, conjuntamente com proatividade e assunção de riscos.
Contribuições teóricas/metodológicas: A pesquisa contribui com a teoria orientação empreendedora avançando e fornecendo novas evidências empíricas às pesquisas ao relacionar o construto com o desempenho, em pet shops. Assim como contribui para o campo da incerteza ambiental, ao verificar seu efeito mediador na relação entre orientação empreendedora e o desempenho organizacional.

Authors: De Lima Anderson Antônio , Ribeiro Thiago de Luca Sant'ana , Costa Benny Kramer
Published: January 2023

Objetivo: O objetivo do estudo é mapear e descrever a evolução conceitual-teórica de stakeholders em relação à competitividade, apresentando as principais influências teóricas e as correntes teóricas fronteiriças da relação entre stakeholders e competitividade.
Método: Trata-se de uma pesquisa de natureza descritiva, realizada por meio de método quantitativo, utilizamos as técnicas bibliométricas de cocitação e acoplamento bibliográfico (pareamento) para mapear a estrutura intelectual que suporta os estudos da relação entre stakeholders e competitividade. Utilizamos a técnica estatística análise fatorial exploratória e o software de mapeamento de dados VOSviewer para analisar os 482 documentos de nossa amostra.
Originalidade/Relevância: A literatura sobre stakeholders e competitividade carece de estudos que examinem a relação entre esses termos. Diante da escassez de trabalhos que relacionem stakeholders e competitividade, este estudo busca preencher essa lacuna teórica mapeando e descrevendo o estoque de conhecimento sobre o tema.
Resultados:  A análise de cocitação identificou cinco clusters, o cluster mais importante teve como viés principal investigar a competitividade de destinos turísticos e a teoria de stakeholders. O acoplamento bibliográfico identificou nove áreas temáticas que os estudos sobre stakeholders e competitividade estão se concentrando, a área que concentra mais estudos consiste na análise da competitividade de destinos turísticos.
Contribuições teóricas: A principal contribuição deste estudo é de caráter exploratório, uma vez que além de mapear a evolução teórica-conceitual, mais especificamente as principais influências teóricas, correntes teóricas existentes e as frentes teóricas atuais que estudam as temáticas stakeholders e competitividade o estudo fornece um ponto de partida para estudos futuros descritivos e causais sobretudo nos clusters formados no mapa de pareamento bibliográfico.
