BackgroundCrimean-Congo hemorrhagic fever (CCHF) continues to pose a serious threat to the fragile healthcare system of Pakistan with a continuous increase of morbidity and mortality. The present study aimed to assess the knowledge, attitudes, and practices regarding CCHF among general people who resided in Pakistan.MethodsAn online cross-sectional survey design was applied, and a convenience sampling technique was used to recruit 1039 adult people from Pakistan. Data were collected from September 08 to October 12, 2021. The questionnaire consisted of a total of 32 questions in four parts assessing socio-demographics, as well as knowledge, attitudes, and practices regarding CCHF. All statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS), and logistic regression analyses were performed to determine the factors associated with good knowledge, positive attitudes, and good practices.ResultsAlarmingly, 51.5% of participants heard about CCHF infection before administering the survey. Among these, 20.2%, 33.3%, and 48.2% of the study participants had demonstrated good knowledge, positive attitudes, and good practices, respectively. Binary logistic regression analysis revealed that education and income status had a significant impact on knowledge and attitudes (p<0.05). Similarly, the mean attitude scores differed significantly by age, education, and income status (p<0.05).ConclusionsThe findings reflected inadequate levels of knowledge, attitudes, and practices regarding CCHF among general people in Pakistan which may regard as lower than expected. As CCHF is a highly contagious disease, it’s urgent to initiate a comprehensive approach to handle the situation before it spreads further in Pakistan.

Published: December 2022

Background
Photoplethysmography (PPG) is a low-cost and easy-to-implement method to measure vital signs, including heart rate (HR) and pulse rate variability (PRV) which widely used as a substitute of heart rate variability (HRV). The method is used in various wearable devices. For example, Samsung smartwatches are PPG-based open-source wristbands used in remote well-being monitoring and fitness applications. However, PPG is highly susceptible to motion artifacts and environmental noise. A validation study is required to investigate the accuracy of PPG-based wearable devices in free-living conditions.

Objective
We evaluate the accuracy of PPG signals—collected by the Samsung Gear Sport smartwatch in free-living conditions—in terms of HR and time-domain and frequency-domain HRV parameters against a medical-grade chest electrocardiogram (ECG) monitor.

Methods
We conducted 24-hours monitoring using a Samsung Gear Sport smartwatch and a Shimmer3 ECG device. The monitoring included 28 participants (14 male and 14 female), where they engaged in their daily routines. We evaluated HR and HRV parameters during the sleep and awake time. The parameters extracted from the smartwatch were compared against the ECG reference. For the comparison, we employed the Pearson correlation coefficient, Bland-Altman plot, and linear regression methods.

Results
We found a significantly high positive correlation between the smartwatch’s and Shimmer ECG’s HR, time-domain HRV, LF, and HF and a significant moderate positive correlation between the smartwatch’s and shimmer ECG’s LF/HF during sleep time. The mean biases of HR, time-domain HRV, and LF/HF were low, while the biases of LF and HF were moderate during sleep. The regression analysis showed low error variances of HR, AVNN, and pNN50, moderate error variances of SDNN, RMSSD, LF, and HF, and high error variances of LF/HF during sleep. During the awake time, there was a significantly high positive correlation of AVNN and a moderate positive correlation of HR, while the other parameters indicated significantly low positive correlations. RMSSD and SDNN showed low mean biases, and the other parameters had moderate mean biases. In addition, AVNN had moderate error variance while the other parameters indicated high error variances.

Conclusion
The Samsung smartwatch provides acceptable HR, time-domain HRV, LF, and HF parameters during sleep time. In contrast, during the awake time, AVNN and HR show satisfactory accuracy, and the other HRV parameters have high errors.
Assessing effectiveness of many-objective evolutionary algorithms for selection of tag SNPs
Authors: Moqa Rashad , Younas Irfan , Bashir Maryam 
Published: December 2022

BackgroundStudies on genome-wide associations help to determine the cause of many genetic diseases. Genome-wide associations typically focus on associations between single-nucleotide polymorphisms (SNPs). Genotyping every SNP in a chromosomal region for identifying genetic variation is computationally very expensive. A representative subset of SNPs, called tag SNPs, can be used to identify genetic variation. Small tag SNPs save the computation time of genotyping platform, however, there could be missing data or genotyping errors in small tag SNPs. This study aims to solve Tag SNPs selection problem using many-objective evolutionary algorithms.MethodsTag SNPs selection can be viewed as an optimization problem with some trade-offs between objectives, e.g. minimizing the number of tag SNPs and maximizing tolerance for missing data. In this study, the tag SNPs selection problem is formulated as a many-objective problem. Nondominated Sorting based Genetic Algorithm (NSGA-III), and Multi-Objective Evolutionary Algorithm based on Decomposition (MOEA/D), which are Many-Objective evolutionary algorithms, have been applied and investigated for optimal tag SNPs selection. This study also investigates different initialization methods like greedy and random initialization. optimization.ResultsThe evaluation measures used for comparing results for different algorithms are Hypervolume, Range, SumMin, MinSum, Tolerance rate, and Average Hamming distance. Overall MOEA/D algorithm gives superior results as compared to other algorithms in most cases. NSGA-III outperforms NSGA-II and other compared algorithms on maximum tolerance rate, and SPEA2 outperforms all algorithms on average hamming distance.ConclusionExperimental results show that the performance of our proposed many-objective algorithms is much superior as compared to the results of existing methods. The outcomes show the advantages of greedy initialization over random initialization using NSGA-III, SPEA2, and MOEA/D to solve the tag SNPs selection as many-objective optimization problem.

This reportseeks to present the outcome of exchanges conducted within the event, Songs of Violated Vereda Wetlands (Veredas Violadas), the most recent celebration of the Sagarana Festival: Becoming Guimarães Rosa for the Backlands (como Rosa para o Sertão), 2 in November 2012.Topics for discussion included conceptual and cultural aspects, and public policies on the ecosystems of vereda wetlands. Special emphasis wasplaced on the perception of traditional populations living in the Brazilian Savannah hinterlands and their relationship to the Veredas, including the expression of traditional life in the work of João Guimarães Rosa3. A typology of the environmental impact on the ecosystems of veredas is presented, based on the regional etymology by which the peoples of the hinterlands interpret these impacts.
O circuito espacial de produção e os círculos de cooperação da cana-de-açúcar: uma análise a partir de Alagoas
Authors: Silva Dênis Carlos da 
Published: December 2022

Investigar a cana-de-açúcar em Alagoas implica em aprofundar a compreensão sobre a
história da formação territorial do estado. Vários aspectos presentes na realidade alagoana
foram herdados da dinâmica da atividade canavieira. Atualmente, destaque no Brasil e
recordista no Nordeste em produção de açúcar e álcool, Alagoas conta com 25 unidades
produtoras (usinas), e exporta seus produtos para muitos países. Esse complexo
sucroalcooleiro se estende principalmente pela Zona da Mata (polo industrial canavieiro).
O circuito espacial de produção da cana-de-açúcar em Alagoas se insere dentro da lógica
global, justamente por atender em grande parte as exigências do mercado externo que faz
com que a produção circule em larga escala, contribuindo, contraditoriamente, para a
reprodução da pobreza local. Para a concretização desses projetos, os chamados agentes
hegemônicos contam com o apoio de instituições públicas e privadas, as quais fazem
possível a confirmação de suas práticas, através das normas e dos círculos de cooperação.
Para a operacionalização dessas ideias, se fez necessário a utilização do conceito de
circuito espacial de produção e de território, este último analisado a partir da categoria uso
do território, sendo estes pressupostos capazes de indicar os vários desvendamentos
inerentes a teia dos circuitos da cana-de-açúcar a partir de Alagoas.

Published: December 2022

O governo brasileiro e os governos locais recorreram à abordagem territorial para a
elaboração de suas estratégias de desenvolvimento regional sustentável. Espaço
geográfico delimitado, dotado de uma governança própria e animado por processos
específicos, o território é visto como o lugar de integração das dimensões social,
econômica e ambiental das diversas políticas públicas. Todavia, apesar do discurso
sobre a integração das diferentes dimensões do desenvolvimento sustentável, a maioria
das ações está polarizada entre a economia e a conservação ambiental. A pesquisa
apresentada neste artigo visa à adoção de um quadro conceitual para avaliação da
dimensão social dos processos territoriais segundo a teoria dos sistemas. Seguindo uma
abordagem iterativa e interdisciplinar, foi estudado o Território Rural Sul Sergipano,
Brasil, considerando o território como um sistema complexo de atores e utilizando um
método de modelagem social computacional baseada na Sociologia da Ação
Organizada. Os resultados mostraram que essa abordagem permitiu a identificação dos
atores pertinentes, assim como os jogos de atores nos quais eles se engajam,
fundamentados, principalmente, nas relações de poder e dependência, contribuindo
assim para a compreensão da estrutura social do território.
Paulo Freire e Educação do Campo: da invasão à ocupação cultural para a liberdade
Authors: Rossi Rafael , Di Giorgi Cristiano Amaral Garboggini 
Published: December 2022

Há um movimento mobilizador que na atualidade vem despertando a atenção de vários setores da sociedade, dentre eles a universidade, esse movimento se chama: Educação do Campo. No entanto, a partir da luta dos trabalhadores rurais, em muitos casos organizados em seus movimentos sociais e sindicais, há a necessária contextualização do conceito em construção da educação pensada a partir dos interesses dessa classe trabalhadora. É nesse intuito que o presente artigo e as reflexões que nele constam, a partir da tese de doutorado em Educação em andamento, o pensamento e a reflexão teórica contida nos escritos do educador Paulo Freire ajudam a desmistificar e distinguir projetos educacionais do campo e para o campo, rumo à garantia dos direitos sociais, dentre eles a educação, e o reconhecimento do campo enquanto território e não somente local da produção.
Acesso a terra e exploração mineira em Moçambique: que implicações para as comunidades locais
Authors: Matos Elmer Agostinho Carlos de , Medeiros Rosa Maria Vieira 
Published: December 2022

Em Moçambique a terra desempenha um papel fundamental nas comunidades locais, onde a mesma para além de ser uma fonte de reprodução social desses grupos, ela se torna extensão dos mesmos, por sedimentar uma ligação com os seus antecedentes, transformando-se em espaços adequados para a sacralização das relações espirituais. O acesso a terra desempenha nas comunidades a sua libertação, fator que desde a ocupação portuguesa nunca chegou a acontecer. Ao longo deste artigo pretendemos defender a hipótese de que depois da independência, apesar do discurso político e da legislação ter defendido que a terra passou a ser do povo moçambicano, a mesma sempre foi utilizada como um meio para alcançar os objetivos dos sistemas políticos vigentes em cada período histórico que sempre representaram interesses contrários aos verdadeiros interesses das comunidades locais. Para sustentar as análises efetuadas ao longo do artigo, recorreremos à análise das diversas legislações aprovadas no país depois da independência, com destaque para a constituição da república, a legislação de terras e a de minas.

Authors: Azevedo Marinete Martins , Leite Laércio Leonel , Baptista Gustavo Macedo de Mello 
Published: December 2022

This study was aimed at assessing the possibility to use digital photographs to evaluate
success of the reclamation of a gravel-mined degraded area. The indicator used to measure
success was the degree of vegetation ground cover. Photographs were taken with a Canon
camera (model Power Shot A 100). On 11th
of October 2003, in a sunny day (without clouds),
a total of 24 photographs were taken of the centre of the 24 experimental plots. All the 24
photographs were processed with ENVI 3.5 software following the same procedures applied
to process satellite scenes. In each scene analysed, two classes - vegetation cover and bared
soil - were identified with the maximum likelihood algorithm. Results showed that digital
photographs can be used in the quantification of vegetation ground cover and that the
technique employed in this study can be applied to evaluate methodologies of reclamation of
mined areas in which the establishment of vegetation is expected. The technique tested in this
study can be employed by government agencies in charge of land reclamation plans because it
is efficient in determining vegetation ground cover, is easy to perform and is not expensive.

Envy and Blame in the UBI Discussion
Authors: Franke Marcel 
Published: December 2022

Abstract
Envy and blame are two concepts that add social preferences to the economic behavior model of homo economicus. These have already been studied in general distributional issues as well as in the Edgeworth box. Building on this, these social preferences are examined specifically in the work-leisure model and applied to the example of a UBI. Here it is shown that envy is rather triggered by different endowments of individuals and blame only by different preferences. In the discussion about a UBI, this insight provides clarity about the normative basis of arguments against “free riders”. In terms of constitutional economics, envy can be combated through equality of opportunity, while blame can be contained through paternalism, at the expense of freedom of action.

Abstract

Objectives
Various comorbidities associated with COVID-19 add up in severity of the disease and obviously prolonged the time for viral clearance. This study investigated a novel ultrasensitive MAGLUMI® SARS-CoV-2 Ag chemiluminescent immunoassay assay (MAG-CLIA) for diagnosis and monitoring the infectivity of COVID-19 patients with comorbid conditions during the pandemic of 2022 Shanghai.

Methods
Analytical performances of the MAG-CLIA were evaluated, including precision, limit of quantitation, linearity and specificity. Nasopharyngeal specimens from 232 hospitalized patients who were SARS-CoV-2 RT-qPCR positive and from 477 healthy donors were included. The longitudinal studies were performed by monitoring antigen concentrations alongside with RT-qPCR results in 14 COVID-19 comorbid participants for up to 22 days. The critical antigen concentration in determining virus infectivity was evaluated at the reference cycle threshold (Ct) of 35.

Results
COVID-19 patients were well-identified using an optimal threshold of 0.64 ng/L antigen concentration, with sensitivity and specificity of 95.7% (95% CI: 92.2–97.9%) and 98.3% (95% CI: 96.7–99.3%), respectively, while the Wondfo LFT exhibited those of 34.9% (95% CI: 28.8–41.4%) and 100% (95% CI: 99.23–100%), respectively. The sensitivity of MAG-CLIA remained 91.46% (95% CI: 83.14–95.8%) for the samples with Ct values between 35 and 40. Close dynamic consistence was observed between MAG-CLIA and viral load time series in the longitudinal studies. The critical value of 8.82 ng/L antigen showed adequate sensitivity and specificity in evaluating the infectivity of hospitalized convalescent patients with comorbidities.

Conclusions
The MAG-CLIA SARS-CoV-2 Ag detection is an effective and alternative approach for rapid diagnosis and enables us to evaluate the infectivity of hospitalized convalescent patients with comorbidities.
Influence of Fe3+ on titanium corrosion in H2SO4 solutions without and with F−
Authors: Liu Xin Xin , Sakairi Masatoshi , Liao Qiang Qiang 
Published: December 2022

Abstract
Influence of Fe3+ on the corrosion of titanium in H2SO4 solution without F− and with F− was investigated by electrochemical tests. The electrochemical test results showed that Fe3+ could significantly inhibit titanium corrosion in H2SO4 solution without F− and with F− by promoting the protective film formation on titanium. Titanium corrosion resistance (Rc) was positively related to the concentration of Fe3+ in H2SO4 without and with F−. A mechanism was proposed for Fe3+ inhibiting the corrosion of titanium in H2SO4 solution without and with F−.
A sampling of environmental data, and its presentation, from a multi-role U.S. coast guard aircraft
Authors: Greer James M. 
Published: December 2022

Abstract
This work presents a summary of environmental data from 3600 h of data collected during operations of a U.S. Coast Guard HC-130H aircraft performing its routine missions over a five-year period. The aircraft operated from multiple U.S. and deployed locations during the data collection period in the tropical and mid-latitudes at altitudes up to 8.5 km (28 kft). The aircraft collected pressure, temperature and humidity data during the period. No aerosol components were sampled (chlorides, sulfur dioxide, etc.). While there was no Time of Wetness sensor, the ISO 9223 definition is used for the present work as an estimator. These data are presented in the context of research into corrosion and environmental severity, or the potential conditions for it. About 40% of the data were collected while the aircraft was parked on the ground at various based and deployed locations. The purpose of this work is to present and summarize the flight data as an aid in providing some context for future research into environmental effects as they relate to both corrosion and environmentally assisted cracking (EAC) of aircraft structure, and perhaps for comparisons with existing or future datasets from aircraft having other missions. Prediction models need realistic, real-world inputs, such as those presented here. An example for the use of these data in corrosion prediction based on the ISO 9223 international standard is presented. Perhaps not surprisingly, these data show that, for this aircraft, conditions most favorable to corrosion occurred while the aircraft was on the ground.
New methodology to reduce power by using smart street lighting system
Authors: Al-khaykan Ameer , Aziz Ali Saleh , Al-Kharsan Ibrahim H. , Counsell John M. 
Published: December 2022

Abstract
One of most important things now is to create smart street and smart lighting system to save enormous electrical energy. Especially Iraq is suffering shortage of electrical energy generation up to 45%. Because of this, Iraq needs to save a lot of electrical energy in the entire country so as to meet the electrical demand and reduce the large amount of CO2 emission. However, this work presents a very unique and economic control lighting system (CLS) for main streets and sidewalks, which can control the lighting system to give sufficient illumination to the drivers and the pedestrians simultaneously. And at the same time, the CLS system can reduce a lot of electrical energy consumption and the CO2 emissions together. However, by using these smart systems with the exciting illumination source in the streets, the CLS can minimize the electrical energy consumed for the lighting at the main roads and the footpath by about 60% and can use the surplus energies to fill the shortage of electricity in the country. Also, this system will increase the lifetime of the lighting system which means further decrease in cost. Finally, this work presents new type of illumination source, high-intensity discharge (HID), which can reduce the electrical consumption much more by up to 90%, when using the CLS with HID.
