PEDAGOGIA CRÍTICA: POR UMA EPISTEMOLOGIA CRÍTICA E INSURGENTE
Authors: Franco Maria Amelia Santoro , Mota Guadalupe Correa , Silva Lisley Gomes
Published: April 2021

RESUMOEste artigo, tecido sob forma de um ensaio crítico, pautado em pesquisas anteriores dos autores, pretende responder às seguintes questões de pesquisa: que outra racionalidade, para além da técnica-instrumental, ainda é possível à Pedagogia? Em reverberação às transformações do contexto contemporâneo, ainda se pergunta:  quais novas urgências interpelam a Pedagogia e quais insurgências são demandadas para a reinterpretação de seu estatuto epistemológico? O artigo teve por finalidade buscar uma reinterpretação epistemológica crítica da pedagogia, repercutindo as novas urgências postas à prática escolar que nos induzem a pensar em uma pedagogia para a vida e para os acontecimentos na vida. Considerou-se como resultado, que essas demandas para a pedagogia deverão circular em torno de quatro princípios insurgentes que lhe darão o caráter de criticidade: a antropo-ontologia, a epistemologia, as práticas e os poderes. Com base nos fundamentos da Pedagogia Crítica de Freire e ainda nas reflexões decorrentes das Epistemologias do Sul, considerou-se como as necessárias insurgências para reafirmar as bases da epistemologia crítica da pedagogia:  a imaginação criativa como ato de resistência; a organização de práticas para visibilizar os invisibilizados, construindo solidariamente espaços de diálogo e presença; a construção de processos pedagógicos de inclusão de outras práticas educativas; abertura de espaços para práticas dialógicas e problematizadoras; e o fortalecimento de práticas de resistências à lógica neoliberal. Finalmente, aposta-se que a Pedagogia seja a ciência que fundamentará processos críticos de ensinar e aprender em espaços escolares e não-escolares.

FORMAÇÃO INICIAL DO PEDAGOGO PARA ESPAÇOS ESCOLARES E NÃO ESCOLARES: UM ESTUDO CURRICULAR
Authors: Medeiros Emerson Augusto de , Araújo Osmar Hélio Alves , Fortunato Ivan
Published: April 2021

Este texto apresenta uma análise curricular acerca da formação inicial do pedagogo para atuação profissional em espaços escolares e não escolares. A questão norteadora é: como se organizam as matrizes curriculares de licenciaturas em Pedagogia de universidades públicas dos Estados do Ceará, da Paraíba e do Rio Grande do Norte, em termos de conteúdos curriculares a respeito da formação inicial do pedagogo para atuação profissional em espaços escolares e não escolares? Em parâmetros metodológicos, fundamenta-se na análise documental de nove (09) projetos pedagógicos de cursos. Conclui-se, entre outros aspectos, que as licenciaturas estudadas necessitam dar mais ênfase, em seus currículos oficiais, aos conteúdos curriculares específicos sobre os espaços escolares e não escolares de Educação. Além disso, foi possível observar que a docência não se apresenta como central nas matrizes curriculares dos cursos, e a Pedagogia, concebida como ciência da educação, ocupa um lugar suplementar nas propostas curriculares analisadas.

A PEDAGOGIA COMO CIÊNCIA DA EDUCAÇÃO: REFLEXÕES EPISTEMOLÓGICAS E CONTRIBUIÇÕES NA FORMAÇÃO DOCENTE
Authors: Silva Mara Aparecida Alves da , Ferreira Lúcia Gracia
Published: April 2021

O estudo em pauta tem como foco a Pedagogia como Ciência da Educação. Assim, sua construção se realizou a partir de uma abordagem qualitativa, por meio da leitura em livros e artigos científicos de autores clássicos que discutem o tema. Teve como objetivo realizar reflexões epistemológicas e sociais sobre a Pedagogia como Ciência da Educação, tecendo um breve diálogo sobre este campo científico e sua contribuição para o debate na formação docente. Destacamos que a discussão se deu a partir da Pedagogia como campo científico, não como campo profissional. Dessa forma, buscamos refletir sobre a historicidade da Pedagogia e sua mutabilidade no fortalecimento como ciência da educação, refletindo sobre a sua natureza epistemológica, construção teórica e metodológica para pensar a formação do professor. O diálogo sobre a temática possibilitou aprendizagens sobre a construção dessa ciência, desde sua origem como condução de criança até sua consolidação como campo científico. É nessa perspectiva de evolução que a Pedagogia contribui na formação docente, principalmente, por meio da Didática.

Russian Legal Mentality: Experience of Reconstruction and Representation of the Phenomenon of "Snitch" meaning "Abuse of Procedural Rights" (Based on the Materials of Russian Legislation of the 17th-19th Centuries)
Authors: Gavrilov S. N.
Published: April 2021

Historical science shows a growing interest in the study of images of the past, images of historical reality; the reconstruction of mentalities is becoming a priority in the field of historical knowledge. The paper aims at finding (developing) methodological tools for a retrospective study of the legal mentality, as well as its subsequent representation.

Historians and legal theorists are paying more and more attention to the process of forming concepts and relevant terminology. At the same time, the "supraconceptual field", namely the field of images, contains a significant potential for both reconstruction and representation of mentalities and historical phenomena (events). The concept itself is only one of the triggers forming images associated with it and partly generated by it. Legal concepts are the object of linguoculturology of law as one of its branches. At the same time, the author believes that the historical legal science should more actively use the appropriate scientific tools on an interdisciplinary basis. In terms of the reconstruction of legal phenomena, their image will help to study the phenomena that are immersed in the mentality of the corresponding era in a more systematic and comprehensive manner. In terms of the representation of legal phenomena, a well-chosen image recognizable by the recipient of the results of legal historical research can serve as a relay of "contextually packed" information (with elements of both rational and evaluative or emotional information) about a legal historical phenomenon.

The paper attempts to reconstruct and represent the phenomenon of a "snitch" in the sense of "abuse of procedural rights" by means of a chronotropic, figurative model. The reconstructive and representational model is based on the image symbol of the trial as "roads-paths-tracksways" and snitches are considered as a "path".

Published: April 2021

Muchos países de América Latina y el Caribe (ALC) y del mundo se encuentran actualmente desarrollando ambiciosos planes para la reactivación económica y la generación de empleo en el período pospandemia. Estos planes representan una oportunidad única para la inclusión de medidas que, al mismo tiempo que reactivan la economía, también apoyan la transición energética de los países de la región. Esta nota técnica busca apoyar a los países de la región en el diseño de planes de recuperación sostenibles, presentando consideraciones que deben ser tomadas en cuenta para el diseño e implementación exitosa de estos planes. Los países de ALC presentan importantes ventajas comparativas para la transición hacia matrices más sostenibles. Particularmente, se destacan la gran cantidad de recursos naturales para la producción de biomasa, energía eólica y solar. Adicionalmente, las subastas para la adjudicación de nueva capacidad energética son habituales en la regionales y tanto desarrolladores internacionales de energías renovables como prestamistas internacionales presentan interés en el financiamiento de dichas inversiones. Es por ello que los países latinoamericanos y del Caribe tienen una oportunidad única para llevar adelante una transición energética sostenible que además incremente los recursos disponibles para dicho fin. Las inversiones sostenibles para fomentar la transición energética deben ser acompañadas de medidas que amplíen el espacio fiscal de los gobiernos, para no comprometer su sostenibilidad. Para alcanzar esto, la presente nota propone discutir los temas asociados a la introducción de mecanismos que permiten impulsar la transición abriendo espacios fiscales, como mecanismos de fijación de precios de carbono, como los impuestos al carbono o los permisos negociables de emisión de carbono. Adicionalmente, se propone la posibilidad de reducir los subsidios a energéticos con grande emisiones o aumentar la eficiencia de los instrumentos con diseños más focalizados, aprovechando el contexto de bajos precios internacionales de la energía.
An Investigation Into the Use of Yoga in Recreational Therapy Practice
Authors: Kee Wiles Abigail , Van Puymbroeck Marieke , Crowe Brandi , Schmid Arlene
Published: April 2021

Yoga is used in health care with a variety of populations, but limited knowledge exists regarding the details of how yoga is implemented in recreational therapy (RT) practice. Therefore, the purpose of this study was to explore how yoga is implemented in RT practice. As part of a nation-wide survey and through the use of individual interviews, this secondary analysis investigated how yoga is being used in RT practice across the United States. Sixteen recreational therapists completed both a nation-wide online survey and semi-structured interviews. Quantitative results describe the populations in which yoga is being used in RT practice, as well as the characteristics of recreational therapists who also are employing yoga in their RT practice. Then, conventional and summative content analysis identified four categories related to yoga in RT practice: recreational therapists’ practices, treatment planning, outcomes, and yoga intervention. The findings revealed that yoga is implemented with a variety of populations as part of RT practice. Yoga should be implemented by recreational therapists who are trained to teach yoga or provide population-specific yoga sessions to meet specific patient needs. Limitations of the study and implications are discussed.

A terapia fotodinâmica (TFD) é uma reação fotoquímica que atua diretamente em tecidos tumorais com intuito de destruí-los, quando aplicada de maneira ideal, sem afetar o tecido saudável. Caso um sensibilizador localize um tecido tumoral por este é anulado, devido à produção de espécies tóxicas como resultado da transferência de energia da molécula para o tecido tumoral, destruindo a anomalia de forma segura. Em sistemas naturais, a biossíntese do óxido de nitrogênio (NO) e suas várias reações biológicas e fisiológicas ocorrem através da interação com metaloproteínas de ferro, rutênio, cobre, cobalto, dentre outros metais de transição. Assim, as reações de NO através de sua coordenação com centros de metal de transição possuem grande potencial e são principais candidatos para cumprir essa função, podem ser citados porfirinas e seus derivados como a tetraazaporfirina.

Authors: Peručić Doris , Puh Barbara
Published: April 2021

The purpose – to analyse the attitudes of the local population and population from the surrounding area on cruise tourism and its further development in the Dubrovnik area. Design – in the first part the paper gives an overview of the features of cruise tourism in the world, followed by the development of cruise tourism in the Mediterranean. Further, the paper analyses Dubrovnik as a cruise destination and the social impact of cruise tourism on the destination. The results of an empirical research are presented in the last chapter as well as therecommendations for further research. Methodology – A questionnaire was used as the research instrument, and the research was carried out in Dubrovnik and the suburbia in the period May – June 2011 on the purposive sample of 350 respondents. Approach – Cruise tourism, due to its positive effect on the local economy, has become a crucial factor in development strategies of the city of Dubrovnik. Due to the strong development of cruise tourism in Dubrovnik, a continuous market research and analysis is necessary in order to find better solutions of the existing and upcoming problems of this most dynamic sector of the leisure industry. Findings – Research results indicate that majority of the citizens are aware of the positive effects from cruise tourism as well as the fact that the traffic jams, created by a large number of cruisers calling the port in the same day, are the main problem the local community is currently facing. It has been ascertained that there is a difference in attitudes between the citizens on the influence of cruise tourism on the quality of life according to where they live and employment in tourism. Originality of the research – Further development of cruise tourism will depend exclusively on the dynamics of solving the existing issues, organisation of demand management and destination product.
Improved Estimates of the Vertical Structures of Rain Using Single Frequency Doppler Radars
Authors: Jameson A. R. , Larsen Michael , Wolff David
Published: April 2021

It is important to understand the statistical-physical structure of the rain in the vertical so that observations aloft can be translated meaningfully into what will occur at the surface. In order to achieve this understanding, it is necessary to gather high temporal and spatial resolution observations of rain in the vertical. This can only be accomplished using radars. It can be achieved by translating radar Doppler spectra into drop size distributions which can then be integrated to calculate variables such as the rain fall rate. A long-standing difficulty in using such measurements, however, is the problem of vertical air motion which can shift the Doppler spectra, and, therefore, significantly alter the deduced drop size distributions and integrated variables. In this work, we illustrate the improvement in measured rain structures using a new approach for removing the effect of mean vertical air motion. It is demonstrated that the new approach proposed here not only produces what appear to be better estimates of the rainfall rates, but, also as a consequence, provides estimates of the temporal and spatial regionally coherent updraft and downdrafts occurring in the precipitation. Furthermore, the technique is readily applicable to other radars especially those operating at non-attenuating frequencies.

Published: April 2021

Heart regeneration after myocardial infarction remains challenging in reconstruction of blood resupply system. Here, we find that in zebrafish heart after resection of the ventricular apex, the local myocardial cells and the clotted blood cells undergo cell remodeling process via cytoplasmic exocytosis and nuclear reorganization within revascularization-based blastema. The regenerative processes are visualized by spatiotemporal expression of three blastema representative factors (alpha-SMA- which marks for fibrogenesis, Flk1for angiogenesis/hematopoiesis, and Pax3a for remusculogensis)，and two histone modifications (H3K9Ac and H3K9Me3 mark for chromatin remodeling). Using the cultured zebrafish embryonic fibroblasts we identify blastema fraction components and show that Krt5 peptide could link cytoskeleton network and BMP4 signaling pathway to regulate the transcription and chromatin accessibility at the blastema representative genes and bmp4 genes. Our study provides new mechanistic insights into the epithelial-dependent and revascularization-based blastema regeneration for potential myocardial infarction therapy.
Simulating Imaging Spectroscopy in Tropical Forest with 3D Radiative Transfer Modeling
Authors: Ebengo Dav M. , de Boissieu Florian , Vincent Gregoire , Weber Christiane , Féret Jean-Baptiste
Published: April 2021

Optical remote sensing can contribute to biodiversity monitoring and species composition mapping in tropical forests. Inferring ecological information from canopy reflectance is complex and data availability suitable to such a task is limiting, which makes simulation tools particularly important in this context. We explored the capability of the 3D radiative transfer model DART to simulate top of canopy reflectance acquired with airborne imaging spectroscopy in complex tropical forest, and to reproduce spectral dissimilarity within and among species, as well as species discrimination based on spectral information. We focused on two factors contributing to these canopy reflectance properties: the horizontal variability in leaf optical properties (LOP) and the fraction of non-photosynthetic vegetation (NPVf). The variability in LOP was induced by changes in leaf pigment content, and defined for each pixel based on a hybrid approach combining radiative transfer modeling and spectral indices. The influence of LOP variability on simulated reflectance was tested by considering variability at species, individual tree crown and pixel level. We incorporated NPVf into simulations following two approaches, either considering NPVf as a part of wood area density in each voxel or using leaf brown pigments. We validated the different scenarios by comparing simulated scenes with experimental airborne imaging spectroscopy using statistical metrics, spectral dissimilarity (within crowns, within species, and among species dissimilarity) and supervised classification for species discrimination. The simulation of NPVf based on leaf brown pigments resulted in the closest match between measured and simulated canopy reflectance. The definition of LOP at pixel level resulted in conservation of the spectral dissimilarity and expected performances for species discrimination. Our simulation framework could contribute to better understand performances for species discrimination and relationship between spectral variations and taxonomic and functional dimensions of biodiversity.
Challenging Islamist Populism in Indonesia through Catholic Youth Activism
Authors: Nilan Pam , Wibowanto Gregorius Ragil
Published: April 2021

This paper reports data from a study of young Catholic activists. They were concerned about the expansion of Islamist populism in democratic Muslim-majority Indonesia. They actively built inter-faith coalitions with local liberal Muslim youth groups, and with pan-national Nahdlatul Ulama (NU), the largest independent Islamic organization in the world. Islamist populism prioritises religious identity over the national identity of citizenship. In framing their citizenship activism against the current tide of Islamist populism, the informants in our study selectively engaged aspects of Catholic theology. They articulated their religious identity as coterminous with a nationalist identity centred on multi-faith tolerance and harmony. That discourse in itself refutes a key principle of Islamist populism, which argues for primordial entitlement.

Published: April 2021

Self-assembled structures mostly arises through enzyme-regulated phenomena in nature under persistent conditions. Enzymatic reactions are one of main biological processes in fabrication and construction of supramolecular hydrogel networks required for biomedical applications. The enzymatic processes provide a unique opportunity to integrate hydrogel formation. In most of cases, structure and substrates of hydrogels are adjusted by enzyme catalysis due to the chemo-, regio- and stereo-selectivity of enzymes. Hydrogels processed by using various enzyme schemes showed remarkable characteristics as dynamic frames for cells, bioactive molecules and drugs in biomedical applications. A novel class of enzyme-mediated crosslinking hydrogels mimics the extracellular matrices by displaying unique physicochemical properties and functionalities like water-retention capacity, drug loading ability, biodegradability, biocompatibility, biostability, bioactivity, optoelectronic properties, self-healing ability, shape memory ability. In recent years, many enzymatic systems investigated hydrogel cross-linking. Results of biocompatible hydrogel products show that these mechanisms of crosslinking can fulfill requirements for variety of biomedical applications including tissue engineering, wound healing and drug delivery.

Published: April 2021

This study was conducted in the Dhanu River and adjacent waters at Mithamain upazila (sub-district) under Kishoreganj district of Bangladesh to prepare a check list of available native fishes with their availability status, conservation perspectives, habitat preferences, population trends and intimidations. Data were collected monthly by direct field survey, focus group discussions, and personal interviews with fishers by using a semi-structured questionnaire and a pictorial check list of fish species. A total of 91 indigenous fish species of 59 genera belonging to 29 families under 11 orders were documented where 17.58% species was abundantly available, 27.47% was commonly available, 31.87% was moderately available and 23.08% was rarely available. Cypriniformes was found as the dominant order, consisting 37.36% of the fish species aggregation and Cyprinidae was the most dominant family with 32.97% of the entire species assemblage. Twenty four piscine species (26.37%) were under threatened category in Bangladesh which subsumed 3 critically endangered (3.29%), 11 endangered (12.08%), and 10 vulnerable species (10.99%). Notably globally threatened Cirrhinus cirrhosus, Channa orientalis, and Wallago attu were available there. Fish population trends of 24.18% and 59.34% of the entire fish species was found in decreasing trends in global and national level, respectively. Leading intimidation to the fish diversity was indiscriminately overfishing, followed by fishing by dewatering of wetlands, katha fishing method, use of deprecated fishing gears, climate change, etc. Minimization of anthropogenic impacts, assuring the flux of water round the year, enactments of fish laws, installation and management of fish sanctuaries, and raising public awareness can be effective for the conservation of existing fisheries resources.
Everything Is A Circle: A New Universal Orbital Model
Authors: Tan AslıPınar
Published: April 2021

Based on measured astronomical position data of heavenly objects in the Solar System and other planetary systems, all bodies in space seem to move in some kind of elliptical motion with respect to each other. According to Kepler’s 1st Law, “orbit of a planet with respect to the Sun is an ellipse, with the Sun at one of the two foci.” Orbit of the Moon with respect to Earth is also distinctly elliptical, but this ellipse has a varying eccentricity as the Moon comes closer to and goes farther away from the Earth in a harmonic style along a full cycle of this ellipse. In this paper, our research results are summarized, where it is first mathematically shown that the “distance between points around any two different circles in three dimensional space” is equivalent to the “distance of points around a vector ellipse to another fixed or moving point, as in two dimensional space”. What is done is equivalent to showing that bodies moving on two different circular orbits in space vector wise behave as if moving on an elliptical path with respect to each other, and virtually seeing each other as positioned at an instantaneously stationary point in space on their relative ecliptic plane, whether they are moving with the same angular velocity, or different but fixed angular velocities, or even with different and changing angular velocities with respect to their own centers of revolution. This mathematical revelation has the potential to lead to far reaching discoveries in physics, enabling more insight into forces of nature, with a formulation of a new fundamental model regarding the motions of bodies in the Universe, including the Sun, Planets, and Satellites in the Solar System and elsewhere, as well as at particle and subatomic level. Based on the demonstrated mathematical analysis, as they exhibit almost fixed elliptic orbits relative to one another over time, the assertion is made that the Sun, the Earth, and the Moon must each be revolving in their individual circular orbits of revolution in space. With this expectation, individual orbital parameters of the Sun, the Earth, and the Moon are calculated based on observed Earth to Sun and Earth to Moon distance data, also using analytical methods developed as part of this research to an approximation. This calculation and analysis process have revealed additional results aligned with observation, and this also supports our assertion that the Sun, the Earth, and the Moon must actually be revolving in individual circular orbits.
Does Maternal Arachidonic Acid Influence the Neurodevelopmental Effects of Docosahexaenoic Acid?
Authors: Duttaroy Asim K.
Published: April 2021

During the last trimester of gestation and for the first 18 months after birth, docosahexaenoic acid,22:6n-3 (DHA) and arachidonic acid,20:4n-6 (ARA) deposited within the cerebral cortex at a rapid rate. The mode of action of these two fatty acids and their derivatives at different structural-function and signaling pathways levels in the brain have been continuously emanating. These fatty acids are also involved in various brain developmental processes; however, their mechanisms of action are not yet well known. Recent data suggest that there may be a need for a balanced proportion of ARA and DHA in infant formula due to their complementary benefits. This review describes the importance of maternal preferential transfer of ARA and DHA to support the infant's optimal brain development and growth and functional roles in the brain.

Published: April 2021

.Functionalization of multi-walled carbon nanotubes (MWNTs) surface with sulfonated poly(ether ether ketone) SPEEK chains using hexane diamine (HAD) as the interlinking molecule was investigated. MWNTs were first oxidized by nitric acid to generate carboxyl groups on their surface. Grafting of SPEEK chains on the MWNTs surface was achieved using hexane diamine as a cross-linking molecule. The attachment took place after the reaction of amine groups with carboxyl groups of oxidized MWNTs and sulfonate groups of SPEEK as confirmed by infrared (FTIR) analysis. Scanning electron microscopy (SEM) showed that MWNTs were packed into a dense and compact structure. Transmission electron microscopy (TEM) showed that the nanotubes were wrapped by polymer chains and arranged in a bundle like structure. These observations reveal that some of MWNTs were interconnected by SPEEK chains.
Using Machine Learning to Map Western Australian Landscapes
Authors: Albrecht Thomas , González-Álvarez Ignacio , Klump Jens
Published: April 2021

Landscapes evolve due to climatic conditions, tectonic activity, geological features, biological activity, and sedimentary dynamics. These processes link geological processes at depth to surface features. Consequently, the study of landscapes can reveal essential information about the geochemical footprint of ore deposits at depth. Advances in satellite imaging and computing power have enabled the creation of large geospatial datasets, the sheer size of which necessitates automated processing. We describe a methodology to enable the automated mapping of landscape pattern domains using machine learning (ML) algorithms. From a freely available Digital Elevation Model, derived data, and sample landclass boundaries provided by domain experts, our algorithm produces a dense map of the model region in Western Australia. Both random forest and support vector machine classification achieve about 98\% classification accuracy with reasonable runtime of 48 minutes on a single core. We discuss computational resources and study the effect of grid resolution. Larger tiles result in a more contiguous map, while smaller tiles result in a more detailed, and at some point, noisy map. Diversity and distribution of landscapes mapped in this study support previous results. In addition, our results are consistent with the geological trends and main basement features in the region.
Income Losses and Subjective Well-Being: Gender and Ethnic Inequalities during the Covid-19 Lockdown Period in the UK
Authors: Giovanis Eleftherios
Published: April 2021

COVID-19 has become a global health pandemic forcing governments introducing unprecedented steps to contain the spread of the virus. On the 23rd of March, 2020, the UK government addressed the nation to announce extraordinary measures as a response to slow down the spread of the coronavirus, which have influenced the well-being and finances of millions of people. As a result people had to make difficult adjustments and to follow different coping strategies in order to respond to income losses. The main objective of this study is to examine the impact of various coping strategies, due to the lockdown measures, on the respondents’ subjective well-being by gender and ethnic background. We apply a difference-in-differences framework using data from the UK Household Longitudinal Study (UKHLS) combined with the UKHLS COVID-19 survey conducted in April 2020. Furthermore, using the Life Satisfaction Approach (LSA), we estimate the well-being costs of the coping strategies adopted that denote the amount required to revert individual’s well-being into the levels were before Covid-19 period. The results show that coping strategies with the earning losses have a significant detrimental impact on well-being and the related costs range between £250-3,500, which are significantly varied by gender and ethnic group.JEL Classification: C1, I14, I31
A Novel Approach to MADM Problems Using Fermatean Fuzzy Hamacher Prioritized Aggregation Operators
Authors: Jan Asmatullah , Khan Asghar , Khan Waqar , Afridi Minhaj
Published: April 2021

A generalized form of union and intersection on FFS can be formulated from a generalized t-norm (TN) and t-conorm (TCN). Hamacher operations such as Hamacher product and Hamacher sum, are good alternatives to produce such product and sum. The Hamacher operations can generate more flexible and more accurate results in decision making process due to the working parameter involved in these operations. The intuitionistic fuzzy set, brifely as; IFS and its extension involving Pythagorean fuzzy set (PFS) and Fermatean fuzzy set (FFS), are all effective tools to express uncertain and incomplete cognitive information with membership, nonmembership and hesitancy degrees. The Fermatean fuzzy set (FF-set) carries out uncertain and imprecise information smartly in exercising decision-making than IFS and PFS. By adjusting the prioritization of attributes in FF-environment, in this course of this article, we first device new operations on FF information using prioritized attributes and by employing HTN and HTCN, we discuss the basic operations. Induced by the Hamacher operations and FF-set, we propose FF Hamacher arithmetic and also geometric aggregation operators (AOs). In the first section, we introduce the concepts of an FF Hamacher prioritized AO, and FF Hamacher prioritized weighted AO. In the second part, we develop FF Hamacher prioritized geometric operator (GO), and FF Hamacher prioritized weighted GO. We study essential properties and a few special cases of our newly proposed operators. Then, we make use of these proposed operators in developing tools which are key factors in solving the FF multi-attribute decision-making situations with prioritization. The university selection phenomena is considered as a direct application for analysis and to demonstrate the practicality and efficacy of our proposed model. The working parameter considered in these AOs is analyzed in different existing and proposed AOs. Further, comparison analysis is conducted for the authenticity of proposed & existing operators.

It is known that several optimization problems can be converted to a fixed point problem for which the underline fixed point operator is an averaged quasi-nonexpansive mapping and thus the corresponding fixed point method utilize to solve the considered optimization problem. In this paper, we consider a fixed point method involving inertial extrapolation step with relaxation parameter to obtain a common fixed point of a countable family of averaged quasi-nonexpansive mappings in real Hilbert spaces. Our results bring a unification of several versions of fixed point methods for averaged quasi-nonexpansive mappings considered in the literature and give several implications of our results. We also give some applications to monotone inclusion problem with three-operator splitting method and composite convex and non-convex relaxed inertial proximal methods to solve both convex and nonconvex reweighted $l_Q$ regularization for recovering a sparse signal. Finally, some numerical experiments are drawn from sparse signal recovery to illustrate our theoretical results.

Background: Although osteoarthritis (OA) is traditionally considered to be nociceptive, our objective was to examine neuropathic pain in the knees of OA patients using the painDETECT questionnaire (PDQ).Methods: A total of 180 knees in 158 consecutive patients who underwent total knee arthroplasty (TKA) were enrolled. The prevalence of neuropathic pain, unclear pain and nociceptive pain was determined before and after TKA. Knee pain was evaluated using a numerical rating scale (NRS). All patients were evaluated preoperatively and 6 months postoperatively. Neuropathic pain and unclear pain were grouped together as possible neuropathic pain. The relationship between possible neuropathic pain and pain intensity was evaluated.Results: Before TKA, neuropathic pain and unclear pain were found in 10 and 30 knees, respectively. The remaining 140 knees were categorized as nociceptive pain. After TKA, the numbers of knees with neuropathic and unclear pain decreased to one and five, respectively. The prevalence of possible neuropathic pain decreased significantly from 22.2% to 3.3% (p < 0.001) after surgery. Among the six knees with possible neuropathic pain postoperatively, four had possible neuropathic pain preoperatively as well, while the remaining two patients had been classified as nociceptive pain preoperatively (p = 0.021). Knees with postoperative possible neuropathic pain had higher postoperative NRS scores than those with nociceptive pain (p = 0.011).Conclusions: The prevalence of possible neuropathic pain decreased significantly after TKA, however, preoperative possible neuropathic pain might affect the presence of persistent postoperative pain.

In construction industry general contractors (GCs) need to manage and conduct numerous projects simultaneously. To this aim, they usually have subcontractors conduct available tasks and projects. So, subcontractor management is becoming a major challenge. To deal with this challenge, GCs aim to reduce total costs of projects including employment /subcontracting costs, indirect costs, tardiness penalties, and the money which must be paid for movement of workforce from one project to another. The aim of current research study is to propose a model for selecting subcontractors and assigning available tasks in the project to them in order to reduce the costs of the GC. Then, a genetic algorithm (GA) is proposed to solve a real problem. The proposed algorithm is innovative from three points of view: (1) generation of initial population; (2) subcontractor assignment approach and (3) the objective function. The problem was also solved by means of an exact method. Then, the results of proposed algorithm were compared to the outcomes of the exact method. This comparison shows that the proposed algorithm can efficiently help GCs select subcontractors and assign available tasks to each subcontractor when several projects must be carried out simultaneously.

The latest research in WSNs (Wireless Sensor Network) has been exploring Underwater Acoustic Sensor Networks (UASNs). As the name suggests, these networks aim at providing effective communication underwater by addressing the challenges prevalent in this network. Underwater communication has found a lot of applications in ocean monitoring and underwater contamination monitoring. The issue of routing underwater is a major concern as it has to address a lot of challenges. Creating an effective routing protocol has been a constant topic of research in UASNs. We have focused on a Secure Cross-Layer Routing Protocol (SCLRP) in UASNs using Fuzzy Logic and Enhanced Algebra Homomorphic Encryption. This protocol aims at providing secure data transmission using optimized nodes that are selected from the neighboring nodes of the source node. The optimal nodes are selected by applying fuzzy rules to the available input. The selected nodes will then forward the packets to the next hop till the packet reaches the destination. The proposed protocol is an Energy Efficient Secure Fuzzy Logic based Cross –Layer design routing protocol. Our proposed protocol ensures safe transmission of data, which is the main objective of a routing protocol used in a wireless network. The routing protocol will ensure better QoS, by using a reliable encryption technique to reinforce secure routing. The protocol incorporates an enhanced Algebra Homomorphic encryption technique to help with managing the security of the transmitted data. QoS is further improved by using a cross-layer design wherein, the proposed protocol will not be expected to adjust as the data travels the different layers of the network so the protocol will be free from the confines of the standards and protocols followed in each of the layer. This flexibility will help in making our protocol perform better than the existing techniques. The SCLRP protocol is analyzed with the performance of NADIR and EEMCCP schemes to analyze its performance.

Published: April 2021

This paper proposes a probabilistic graphical model that integrates interpretive structural modeling (ISM) and Bayesian belief network (BBN) approaches to predict CPT-based soil liquefaction potential. In this study, an ISM approach was employed to identify relationships between influence factors, whereas BBN approach was used to describe the quantitative strength of their relationships using conditional and marginal probabilities. The proposed model combines major causes, such as soil, seismic and site conditions, of seismic soil liquefaction at once. To demonstrate the application of the propose framework, the paper elaborates on each phase of the BBN framework, which is then validated with historical empirical data. In context of the rate of successful prediction of liquefaction and non-liquefaction events, the proposed probabilistic graphical model is proven to be more effective, compared to logistic regression, support vector machine, random forest and naïve Bayes methods. This research also interprets sensitivity analysis and the most probable explanation of seismic soil liquefaction appertaining to engineering perspective.
