Authors: Guo Wei , Luo Zhenyu , Chen Hexiong , Hang Feilu , Zhang Jun , Al Bayatti Hilal
Published: October 2022

Boosting is an ensemble learning method that combines a set of weak learners into a strong learner to minimize training errors. AdaBoost algorithm, as a typical boosting algorithm, transforms weak learners or predictors to strong predictors in order to solve problems of classification. With remarkable usability and effectiveness, AdaBoost algorithm has been widely used in many fields, such as face recognition, speech enhancement, natural language processing, and network intrusion detection. In the large-scale enterprise network environment, more and more companies have begun to build trustworthy networks to effectively defend against hacker attacks. However, since trustworthy networks use trusted flags to verify the legitimacy of network requests, it cannot effectively identify abnormal behaviors in network data packets. This paper applies Adaboost algorithm in trustworthy network for anomaly intrusion detection to improve the defense capability against network attacks. This method uses a simple decision tree as the base weak learner, and uses AdaBoost algorithm to combine multiple weak learners into a strong learner by re-weighting the samples. This paper uses the real data of trustworthy network for experimental verification. The experimental results show that the average precision of network anomaly detection method based on AdaBoost algorithm is more than 0.999, indicating that it has a significant detection effect on abnormal network attacks and normal network access. Therefore, the proposed method can effectively improve the security of trustworthy networks.

Von der Armenfürsorge zur sozialen Hilfe
- Organisation und Finanzierung in Graubünden (19. und 20. Jahrhundert)
Authors: Aliesch Georg
Published: October 2022

In Graubünden war die Armenfürsorge zunächst eine Aufgabe der Gemeinden. Diese waren damit oft überfordert. Das Niederlassungsgesetz von 1874 berechtigte neu die politischen Gemeinden, die Fürsorge anstelle der Bürgergemeinden wahrzunehmen. Vielerorts blieb aber lange unklar, von welcher «Gemeinde» die Fürsorgelasten zu tragen waren. Der Kanton seinerseits trat erst spät als Akteur in der sozialen Hilfe auf. Er unterstützte viele «Defizitgemeinden» mit namhaften Beiträgen an ihre Armenausgaben.
Mit welchen behördlichen Strukturen, finanzpolitischen Instrumenten und ökonomischen Folgen begegnete man in Graubünden im 19. und 20. Jahrhundert sozialer Not? In welcher Weise veränderte sich das Gesicht der sozialen Hilfe? Anhand der kantonalen Erlasse und weiterer Quellen sowie mit einem vertiefenden Blick auf die Verhältnisse in einigen ausgewählten Gemeinden liefert das Buch Antworten und schliesst eine Forschungslücke.
Élus en lui avant la fondation du monde - Une approche africaine pour comprendre la grâce
Authors: Bujo Bénézet
Published: October 2022

Dieu en qui le muntu (la personne humaine) a préexisté constitue la dynamique de sa vie. Celle-ci se manifeste et se déploie à travers l’acte d’engendrement et d’enfantement mutuels entre les vivants, les morts et les non-encore-nés. Par ailleurs, cet engendrement/enfantement mutuel embrasse toutes les relations de la personne humaine avec le monde cosmique. C’est alors la vie telle que Dieu l’a voulue qui s’articule et s’épanouit. Pour le muntu africain cela est précisément la grâce provenant de Dieu en qui et par qui les bantu (les humains) et tout l’univers existent. Les problèmes écologiques sont donc étroitement liés à la question de la grâce.

Authors: Talib Roaa Hatem , Helal May Mohammed , Naji Raid Kamel
Published: October 2022

In this paper, the aquatic food chain model, consisting of Phytoplankton, Zooplankton, and Fish, in the contaminated environment is proposed and studied. Modified Leslie–Gower model with Holling type IV functional response are used to describe the growth of Fish and the food transition throughout the food chain, respectively. The toxic substance affects directly the Phytoplankton and indirectly the other species. The local stability analysis of all possible equilibrium points is done. The persistence conditions of the model are established. The basin of attraction for each point is specified using the Lyapunov function. Bifurcation analysis near the coexistence equilibrium point is investigated. Detecting the existence of chaos is carried out using bifurcation diagrams. Numerical simulation shows that the food chain has rich dynamics including chaos. Moreover, the existence of toxic substances works as a stabilizing factor in the model.

Published: October 2022

In the present investigation, (NiO:WO3 ) thin films were deposited at RT onto glass substrates  using PLD technique employing focused Nd:YAG laser beam at 600 mJ with a frequency second radiation at 1064 nm (pulse width 9 ns) repetition frequency (6 Hz), for 400 laser pulses incident on the target surface .The structural, morphological and optical properties of the films doped with  different concentration of  Au content (0.03, 0.05, and 0.07) were examined with X-ray diffractometer(XRD), Atomic Force Microscope(AFM) , UV–Vis spectrophotometer . The results show that the films were amorphous with small peaks appearing when doped with AuNPs . The XRD peaks of the deposited NiO:WO3 were enhanced with increasing the Au content  .  The crystalline size of the deposited thin films was calculated using Debye Scherer formula and found to decrease from 6.6 nm for undoped NiO:WO3 to  3.4 nm for doped (NiO:WO3) with the increase of Au content from x=0 to x=0.07  at preferred orientation of (200). All the samples have a cubic structure. Also, the results showed that Au content of the films affects the surface morphology. From the results of AFM analysis, it was found that the roughness and average diameter change when adding Au to the structure, with the highest value occurring at Au ratio 0.03 equal to 7.58 and 81.02 nm, respectively. UV–Vis spectrophotometer was used to investigate the optical transmission. It was found that when Au content of films increased, the transmittance of films decreased.

Published: October 2022

The present work aims to evaluate the content of some toxic metals in chemical and organic fertilizers purchased from local markets in Baghdad, Iraq. The analysis was performed by laser-induced breakdown spectroscopy (LIBS) system. The emission spectral lines of lead (Pb), chromium (Cr), cadmium (Cd) and cobalt (Co) have been recorded to determine the best peak representing each element according to the NIST database. The validity of the LIBS procedure was checked by cross-validating the obtained results using atomic absorption spectroscopy (AAS) with a maximum relative error of 5.3%. Moreover, for qualitative analysis, Pb I 296.64 nm emission line was determined to be superior for the evaluation of lead content in terms of three calibration methods: the external standard (ES), the internal standard (IS), and the multiple linear regression (MLR). The linear correlation coefficient values were : 0.94, 0.97 and 0.992, respectively. LIBS results based on the multiple linear regression (MLR) model have demonstrated better performance and were adopted in the assessment of the Pb content in solid fertilizer samples.

Published: October 2022

Complications associated with diabetes are a consequence of acute disturbance in glucose metabolism in a human body. The most significant complication of diabetes is bone disorders which contributes to high levels of bone disability. This study included 118 diabetic patients, 56 males, 62 females, and 60 healthy non-diabetic controls, 30 males, 30 females. The patients and controls were age matched. Circulating levels of bone function markers (osteoprotegerin, vitamin D, PTH, total calcium and inorganic phosphorus) were determined in all subject groups. The data obtained from this study showed that the serum levels of osteoprotegerin had significantly increased in both diabetic male & female in both age ranges which were 496.3±61.46 pg/mL & 335.7±29.33 pg/mL; 329.8±48.78 pg/mL & 219.9±18.72 pg/mL respectively, in comparison with its level in control matched age ranges 294.6±26.19 pg/mL & 226.8±28.07 pg/mL; 215.7±31.85 pg/mL & 171.9±14.19 pg/mL respectively. Serum calcium concentration had non-significantly increased both in the diabetic males and females in both age ranges which were 11.10±0.46 mg/dL & 11.76±0.74 mg/dL; 10.33±0.33 mg/dL & 10.28±0.48 mg/dL respectively, when compared with its level in control matched age ranges 10.46±0.34 mg/dL & 10.14±0.35 mg/dL;9.69±0.41 mg/dL & 10.08±0.45 mg/dL. Serum vitamin D, parathyroid hormone (PTH) and inorganic phosphorus concentrations had significantly decreased both in the diabetic male and female subjects in both age ranges which were 5.78±1.30 ng/mL and 2.47±0.12 ng/mL; 9.47±1.98 ng/mL, and 10.70±2.11 ng/mL; 74.78±7.42 pg/mL & 67.83±3.69 pg/mL;42.94±2.00 pg/mL & 15.51±1.98 pg/mL; 4.34±0.27 mg/dL & 4.76±0.35 mg/dL; 4.38±0.21 mg/dL; 5.12±0.44 mg/dL respectively when compared with their level in control matched age ranges 13.07±2.13 ng/mL & 15.53±3.40 ng/mL; 57.49±5.64 pg/mL & 62.61±3.71 pg/mL; 5.12±0.44 mg/dL & 5.35±0.37 mg/dL respectively.

Published: October 2022

This research describes a straightforward procedure for extracting the pigment of Methylene Blue (MB) dye from aqueous solutions by utilizing a low-cost, safe, natural, and national source. Batch adsorption experiments were carried out to determine contact time, adsorbent dose, and the starting concentration of the adsorbate. For the analysis, a UV spectrophotometer was employed. Dye adsorption equilibrium was obtained after 120 minutes of contact time. Temkin, Langmuir, and Freundlich isotherm adsorption were used at solution concentrations of (3, 4, 6, and 8) mg/l. Adsorption data is used to predict the pseudo first and pseudo second order kinetic equations, Elovich kinetic models, and intra-particle diffusion using pseudo first and pseudo second order kinetic equations. The Langmuir adsorption model fits the MB adsorption data better than other isotherm models, with the MB capacity at 8 mg/l equal to 0.992 mg/g. The pseudo-second-order model and the adsorption kinetic data are satisfactorily related.
Mathematical Analysis of Peristaltic Pumps for Fene-P model subject to Hall and Joule impact
Authors: Hasen Saba S. , Kareem Rabiha S. , Ali Hayat A.
Published: October 2022

A mathematical model is developed to discuss the impact of the Hall current and the Joule heating on the peristaltic flux of finitely extensible nonlinear elastic Peterlin (FENE-P) fluid in a tapered tube with mild stenosis. The fluid movement  along the wall surface resulted from the sinusoidal wave flowing with constant speed. Conditions of velocity and thermal slip are applied. Lubrication approximation is adopted to modify the governing flow problem. To discover the solution to a system of equations, the regular perturbation approach is used. The effects of the different physical parameters are debated and graphically shown in a set of figures. It is discovered that as the Hall current parameter is increased and the Hartman number is decreased, the fluid velocity increases. It is  also worth noting that the Dufour number causes the fluid temperature to rise, whilst the Hall current parameter causes the temperature to fall. In the meantime, both the Hall current parameter and the Soret number have the opposite effect on concentration. The trapping phenomenon is thoroughly investigated.

Published: October 2022

This review explores the Knowledge Discovery Database (KDD) approach, which supports the bioinformatics domain to progress efficiently, and illustrate their relationship with data mining. Thus, it is important to extract advantages of Data Mining (DM) strategy management such as effectively stressing its role in cost control, which is the principle of competitive intelligence, and the role of it in information management. As well as, its ability to discover hidden knowledge. However, there are many challenges such as inaccurate, hand-written data, and analyzing a large amount of variant information for extracting useful knowledge by using DM strategies. These strategies are successfully applied in several applications as data warehouses, predictive analytics, business intelligence, bioinformatics, and decision support systems. There are many DM techniques that are applied for disease diagnostics and treatment, for example cancer diseases that are investigated using multi-layer perception, Naïve Bayes, Decision Tree, Simple Logistic, K-Nearest Neighbor. As will be explored in this paper. Consequently, for future perspectives there is research in progress for real Iraqi data of Breast Cancer using Data Mining techniques, specifically the Tree decision and K-nearest algorithms.
A Comparative Study Using DCT, Delta Modulation, and Double Shift Coding for Compressing Electroencephalogram Data
Authors: Hadi Hend , George Loay E.
Published: October 2022

Storing, transferring, and processing high-dimensional electroencephalogram (EGG) signals is a critical challenge. The goal of EEG compression is to remove redundant data in EEG signals. Medical signals like EEG must be of high quality for medical diagnosis. This paper uses a compression system with near-zero Mean Squared Error (MSE) based on Discrete Cosine Transform (DCT) and double shift coding for fast and efficient EEG data compression. This paper investigates and compares the use or non-use of delta modulation, which is applied to the transformed and quantized input signal. Double shift coding is applied after mapping the output to positive as a final step. The system performance is tested using EEG data files from the CHB-MIT Scalp EEG Database. Compression Ratio (CR) is used to evaluate the compression system performance. The results are encouraging when compared with previous works on the same data samples.

Published: October 2022

Skin cancer is the most serious health problems in the globe because of its high occurrence compared to other types of cancer. Melanoma and non-melanoma are the two most common kinds of skin cancer. One of the most difficult problems in medical image processing is the automatic detection of skin cancer. Skin melanoma is classified as either benign or malignant based on the results of this test. Impediment due to artifacts in dermoscopic images impacts the analytic activity and decreases the precision level. In this research work, an automatic technique including segmentation and classification is proposed. Initially, pre-processing technique called DullRazor tool is used for hair removal process and semi-supervised mean-shift algorithm is used for segmenting the affected areas of skin cancer images. Finally, these segmented images are given to a deep learning classifier called Deep forest for prediction of skin cancer. The experiments are carried out on two publicly available datasets called ISIC-2019 and HAM10000 datasets for the analysis of segmentation and classification. From the outcomes, it is clearly verified that the projected model achieved better performance than the existing deep learning techniques.
Elliptic Curve Cryptography Performance Evaluation for Securing Multi-Factor Systems in a Cloud Computing Environment
Authors: G.O. Ogunleye  , Akinsanya S.E.
Published: October 2022

In the contemporary world, the security of data and privacy policies are major concerns in cloud computing. Data stored on the cloud has been claimed to be unsafe and liable to be hacked. Users have found it difficult to trust their data in the cloud. Users want to know that their data is accessible from anywhere and that an unauthorized user will not be able to access it. Another area of concern is the authentication of users over the cloud. There are a number of security concerns with Cloud Computing which include Distributed Denial of Service, Data leakage, and many more, just to mention a few. In this paper, an Elliptic Curve Cryptography (ECC) algorithm is used for the encryption and decryption of the information stored on the cloud, so that if someone gains access to the server, it would be unable to access the original information. Performance evaluation of the developed system is performed by comparing ECC with the RSA algorithm. The results show that the ECC method is more efficient than RSA when used to secure information in the cloud.
Study of Micellar Behavior of a Tween 80 Surfactant in Aqueous Media Containing Diphenhydramine Hydrochloride
Authors: Azeez Maryam A. , Ali Inaam H. , Kareem Sameer H.
Published: October 2022

The surface properties of mixtures of a nonionic surfactant Tween 80 (Tw 80) and a cationic drug, diphenhydramine HCl (DPH) have been investigated. This was done by calculating the surface excess concentration (Γmax), minimum molecular area (Amin), surface pressure at the CMC (ᴨcmc), Gibbs Free Energy of adsorption (ΔG°ads), Gibbs free energy of micellization (ΔG°m), the standard enthalpy of micellization (ΔH°m), and the standard entropy of micellization (ΔS°m). The calculation was performed using the surface tension in the temperature range of 293-323 K with the variation of surfactant concentration to determine the critical micelle concentration (cmc) of the system studied. The variation of cmc values of drug concentration (DPH) with temperature was used to calculate the parameters above. The results indicate that the cmc values of Tw 80 increased when the (DPH) was added and when the temperature increased at the whole temperature studied. The results obtained for interfacial properties show that Γmax decreases with the addition of DPH and decreases with DPH concentration increase from 10-5 to 10-4M and decreases with temperature increases. The results of thermodynamic properties indicate that the micellization and adsorption at the interface are spontaneous and the ΔG̊ads are more negative than ΔG̊m at all temperatures.
Depositional Conditions and Nature of Source Rocks of the Upper Part of the Balambo Formation in Northeastern Iraq Based on Rare Earth Elements Data
Authors: Al-Miamary Falah Abed , Al-Lhaebi Safwan Fathi , Al-Juboury Ali Ismail , Swennen Rudy
Published: October 2022

The sequence in the upper part of the Balambo Formation is composed mainly of limestone alternating with marly limestones and dark grey shale in the Bosheen section (eastern Sulaymaniyah, northeastern Iraq) and has been studied in terms of its rare earth element (REE) content. The REEs are very low compared to modern marine sediments. They are depletion in LREEs, and enrichment in HREEs and (La/Yb)N in the studied rocks, indicating that these sediments retained the REEs pattern of marine waters. The negative Ce anomaly reflects direct sedimentation from marine waters under anoxic conditions with the contribution of terrigenous clays. The positive correlation of ∑REEs with Al, Ti, and Y, and the negative correlation of ∑REEs with CaO, in addition to the variation in Y/Ho ratio, all may indicate the presence of terrigenous fractions as the main source for REEs in the studied strata. The REEs pattern of the upper part of the Balambo Formation mostly shows original characteristics, some of which were modified by detrital input. According to (La/Yb)N ratios, the sedimentation rate varied during the deposition of the Balambo Formation in the function of its position along the continental margin.

Authors: Assegie Tsehay Admassu , Dr. Tamilarasi  , Kumar N .Komal
Published: October 2022

Heart disease identification is one of the most challenging task that requires highly experienced cardiologists. However, in developing nations such as Ethiopia, there are a few cardiologists and heart disease detection is more challenging. As an alternative solution to cardiologist, this study proposed a more effective model for heart disease detection by employing random forest and sequential feature selection (SFS). SFS is an effective approach to improve the performance of random forest model on heart disease detection. SFS removes unrelated features in heart disease dataset that tends to mislead random forest model on heart disease detection. Thus, removing inappropriate and duplicate features from the training set with sequential feature selection approach plays significant role in improving the performance of the proposed model. The proposed feature selection approach is evaluated using real world clinical heart disease dataset collected from University of California Irvine (UCI) data repository. Empirical test on validation set reveals that the proposed model performs well as compared to the existing methods. Overall, the state of-the-art heart disease detection model with classification accuracy of 98.53% is proposed for heart disease detection using SFS and random forest model.

The creation and characterization of laser-generated plasma are affected by laser irradiance, representing significant phenomena in many applications.  The present work studied the spectroscopy diagnostic of laser irradiance effect on Zn plasma features created in the air by a Q-switched Nd: YAG laser at the fundamental wavelength (1064nm).  The major plasma parameters (electron temperature and electron density) have been measured using the Boltzmann plot and the Stark broadening methods.  The value of electrons temperature ranged from 6138–6067 K, and the electron density in the range of 1.4×1018 to 2×1018 cm-3, for laser irradiance range from 2.1 to 4.8×108 (W/cm2).  The McWhirter criterion for preserving a local thermodynamic equilibrium (LTE) condition is confirmed in this study.  Furthermore, other fundamental plasma parameters, such as Debye length (λD), number of particles in Debye sphere (ND), and plasma frequency (ωp), were measured. We found that all plasma parameters are affected by laser intensity.

The bound radial wave functions of Cosh potential which are the solutions to the radial part of Schrodinger equation are solved numerically and used to compute the size radii; i.e., the root-mean square proton, neutron, charge and matter radii, ground density distributions and elastic electron scattering charge form factors for nitrogen isotopes 14,16,18,20,22N. The parameters of such potential for the isotopes under study have been opted so as to regenerate the experimental last single nucleon binding energies on Fermi's level and available experimental size radii as well.

Durante a pandemia de COVID-19, foram observadas manifestações atípicas em pacientes pediátricos em diversas regiões do mundo, e o conjunto desses sintomas caracterizou uma nova patologia denominada Síndrome Inflamatória Multissistêmica em Crianças (MIS-C), ou Síndrome Inflamatória Multissistêmica Pediátrica Temporariamente associada ao COVID-19 (PIMS-TS). O objetivo desta revisão foi analisar as manifestações clínicas e as possíveis complicações relacionadas a tal quadro inflamatório. Foi realizada uma busca por artigos científicos nas bases de dados Embase, PubMed e Web of Science, por meio da combinação dos descritores “MIS-C”, “PIMS-TS” e “COVID-19”. Após a análise dos artigos encontrados, e considerando critérios de inclusão e exclusão, foram selecionados 15 estudos para compor esta revisão. A maioria dos estudos mencionaram complicações gastrointestinais, cardiovasculares, respiratórias e mucocutâneas. Ademais, foram encontrados marcadores que indicavam estado inflamatório generalizado e coagulopatia. Assim, concluiu-se que MIS-C provavelmente é uma síndrome manifestada após a infecção por SARS-CoV-2, podendo ocasionar quadros mais graves, mas com baixas taxas de mortalidade.

O Diabetes Mellitus Gestacional é definido como doença que se caracteriza pelos altos níveis de glicemia sanguínea, diagnosticada durante a gestação. Este adoecimento pode acarretar várias complicações maternas e fetais, muitas vezes, necessitando de internamento precoce e cuidados avançados. Objetivou-se caracterizar o perfil epidemiológico de gestantes com diabetes mellitus gestacionais atendidas em serviço de referência. Trata-se de estudo descritivo, documental, retrospectivo, de caráter quantitativo, realizado com gestantes atendidas na maternidade do Hospital Regional do Sudoeste – PR, Francisco Beltrão. A amostra foi constituída por 216 gestantes, cujos dados foram coletados dos prontuários das pacientes. Incluíram-se as gestantes atendidas e diagnosticadas com diabetes mellitus gestacional no período de 2020 e com pelo menos um exame de glicose em jejum ou um teste de tolerância oral à glicose para comprovação diagnóstica. Foram exclusas as gestantes dos anos de 2019 e 2021 e oito transferências. A amostra teve maior porcentual do Diabetes mellitus gestacional (90,7%), com prevalência na raça branca (69,9%), faixa etária de 15-35 anos (68,5%). Ademais, 65,7% realizaram controle com dieta e 32,4 % necessitaram realizar o uso de insulina e 51,9% delas eram obesas. A presente pesquisateve considerável relevância, pois permitiu obter perfil epidemiológico de gestantes diagnosticadas com diabetes mellitus, trazendo benefícios, como identificação precocemente da doença, de modo a evitar complicações para gestantes e bebês.

Introdução: No final do ano de 2019 surgiu na China uma doença infectocontagiosa de característica respiratória e alto grau de disseminação até então desconhecida. No Brasil o primeiro caso de Covid-19 foi confirmado no final de fevereiro de 2020 e a primeira morte em meados de março. Segundo dados da plataforma Coronavírus Brasil, em 17 de março de 2021, houve registro de 11.603.535 casos confirmados e 282.127 óbitos. Objetivo: Descrever o perfil de pessoas que morreram tendo como causa básica do óbito a Covid-19, em um município do Sudoeste do Paraná, entre os anos de 2020 e 2021. Metodologia: Trata-se de um estudo transversal, descritivo, documental de caráter quantitativo que foi realizado na prefeitura municipal de Francisco Beltrão. Resultados: Houve prevalência de óbitos em pacientes do sexo masculino, idosos, com presença de alguma comorbidade associada, sendo hipertensão a mais citada (50,8%). Os sintomas mais prevalentes foram tosse (74,4%), dispneia (56,3%) e saturação < 95% (48,3%), necessitando ainda de hospitalização em algum período da doença (94,1%), sendo os leitos de Sistema Único de Saúde os mais procurados (74,4%). Quanto à taxa de ocupação 49,6% dos casos necessitou apenas de leitos de enfermaria e 42% unidades de terapia intensiva. Discussão: Diversas pesquisas apontam que o sexo masculino é o mais acometido por condições graves de saúde, devido à demora na busca de assistência médica. No que se refere à idade, neste estudo, a prevalência de óbitos se deu entre 71 e 75 anos (15,1%) o que justifica que o envelhecimento é um fator de risco elevado para complicações da doença. Durante a análise dos dados, notou- se que grande parte dos pacientes que tiveram como desfecho o óbito, possuíam algum fator associado, dentre os mais citados, verificou-se a Hipertensão Arterial Sistêmica (50,8%) Diabetes Mellitus (24,8%), doenças cardiovasculares (23,9%) e obesidade (14,7%). No que diz respeito à hospitalização, nesse estudo notou-se que 74,4% da amostra foram hospitalizadas em leitos de SUS, 18,5% em hospitais particulares e 7,1% não possuíam essa informação. Conclusão: É possível observar a importância do estudo epidemiológico para identificar o perfil da população em risco, podendo auxiliar no planejamento do atendimento, rastreamento e controle da doença, além de conhecer a evolução da patologia, a fim de buscar ações adequadas para seu enfrentamento.

O presente trabalho traz o relato de experiência da criação de um perfil no Instagram®, realizado pela Câmara de Ensino, Pesquisa e Extensão (CENPEX) da Faculdade Ciências da Vida (FCV) de Sete Lagoas, Minas Gerais, como meio de disseminar informações científicas ao público interno e externo à FCV. Diante da impossibilidade de se realizar atividades extensionistas no formato presencial, devido à pandemia da Covid-19, o ensino da FCV foi interrompido de modo presencial em março de 2020 e passou a ser remoto. Desta forma, foi criado, pela CENPEX, um projeto de extensão e pesquisa voltado para divulgação científica nas redes sociais envolvendo temáticas na área de saúde, meio ambiente, sustentabilidade e direitos humanos. O grupo de extensão e pesquisa, composto por professores e pesquisadores da FCV, selecionou alunos de diferentes cursos da faculdade e os direcionou à criação de um perfil no Instagram® denominado @cenpexfcv que passou a ter o papel principal de difundir informações científicas confiáveis. O objetivo foi de conscientizar a população em geral no entendimento de diferentes temáticas relacionadas especialmente à Covid-19, em virtude da pandemia, de modo a combater fake news. O perfil disponibiliza posts, animações, informativos, folders, enquetes e lives com profissionais especialistas, que buscam sanar as dúvidas dos seguidores. Ao longo dos oito meses de projetos, já foram montadas 94 formas interativas de divulgação, que, quantitativamente, tem mostrado o crescimento no engajamento, considerado como um aspecto positivo do projeto. Dessa forma, pode-se inferir que o uso de mídias sociais, como o Instagram®, quando utilizada de forma direcionada e com informações fidedignas, podem contribuir efetivamente para o desenvolvimento da divulgação científica.

O objetivo do estudo a seguir é analisar a viabilidade da Universidade Federal da Integração Latino-americana - UNILA montar e manter uma estrutura própria para a realização de concursos públicos, comparando com o custo de contratar um outro órgão para realizar o serviço. Trata-se de uma pesquisa descritiva, com abordagem quantitativa-qualitativa, utilizando-se de pesquisa documental e de um estudo de caso. Foram levantados, através de visita acadêmica à instituição, os valores referentes a orçamentos apresentados por órgãos realizadores de concursos, e os autores fizeram pesquisa sobre os valores para a estruturação própria. Concluiu-se que é mais vantajoso para a instituição contratar um órgão externo para a realização do concurso, sendo necessário que haja pelo menos 4 concursos ao ano para que esta vantagem seja revertida, e a Universidade não possui uma demanda suficiente por contratação de servidores que justifique esta quantidade de concursos anuais.
