Authors: Szymański Michał , Przestacki Damian , Szymański Paweł
Published: November 2022

Metal matrix composites (MMCs) are a special class of materials carrying combined properties that belongs to alloys and metals according to market demands. Therefore, they are used in different areas of industry, and the properties of this type of material are useful in engineering applications. Machining of such composites is of great importance to finalize the fabrication process with improved part quality. However, the process implies several challenges due to the complexity of the cutting processes and random material structure. The current study aims to examine machinability characteristics. Effects of turning a metal matrix composite built of Al2O3 sinter, saturated with an EN AC-44000 AC-AlSi11 alloy, are presented in this paper. In the present study, a turning process of new metal matrix composites was carried out to determine the state-of-the-art material for various engineering applications. During the turning process, the cutting forces, a tool’s wear, and surface roughness were investigated. Further, the SEM (scanning electron microscope) analysis of cutting inserts was performed. The influence of MMC structure on the machining process and surface roughness was studied. The Al2O3 reinforcements were used in different graininess. Effects of conventional turning of the metal matrix composite with Al2O3 sinter of FEPA (Federation of European Producers of Abrasives) 046 and FEPA 100 grade were compared. Results analysis of these tests showed the necessity of continuing research on turning metal matrix composites built of an AlSi alloy and Al2O3 ceramic reinforcement. The study showed the properties of MMCs that influenced machinability. In this paper, the influence of feed rate’s value on surface roughness was carried out. The significant tool wear during the turning of the MMC was proved.

Published: November 2022

Polycrystalline PbTe:In films on a polyimide substrate were obtained and investigated. Their structural and transport properties in a wide range of temperatures (10–300 K) were studied. The unique feature of In impurity in PbTe is the stabilization of the Fermi level (pinning effect) that allowed for the preparation polycrystalline films with the same carrier concentration. We found that heat treatment in an argon atmosphere does not change the average grain size and carrier concentration for as-grown films but greatly increases the Hall mobility and the electron mean free path. By comparing the mobility in the bulk and in the film after heat treatment, we extracted the value of the mobility that arises due to scattering at the grain boundary barriers. The ultimate goal of the present study is the development of these films in designing portable uncooled photodetectors for the mid-IR range.

Published: November 2022

Background and Objectives: Polymyositis and dermatomyositis (PM/DM) are classified as polygenic autoimmune diseases, whereas inflammatory bowel disease (IBD) is considered a polygenic autoinflammatory disease. In the literature, several cases exist reporting the co-occurrence of both conditions. At the molecular level, PM/DM and IBD share common genetic determinants including interferon regulatory factor and vitamin D receptor susceptibility loci. Accumulating evidence underline several indicators that confer poor prognosis in IBD, including antinuclear antibody positivity and the presence of other autoimmune diseases, therefore the aim of this study is to assess the association between these entities. Materials and Methods: This is a population-based retrospective study using data retrieved from a large electronic medical record in Israel, the Clalit health registry. The sample included PM/DM patients and age- and sex-frequency matched controls. The prevalence of IBD in PM/DM was compared between the two groups and logistic regression was applied to control for confounding variables. Predictors of IBD in patients with PM/DM were also explored. Results: Our study included 12,278 subjects with 2085 PM/DM patients and 10,193 age- and sex- frequency-matched controls. The incidence of IBD in patients with PM/DM was significantly higher even after controlling for various confounding variables (OR of 1.73, 95% CI 1.05–2.86, p-value = 0.033). Anti-nuclear antibodies (ANA) positivity was found to be an independent predictor for IBD diagnosis in patients with PM/DM (OR 3.67, 95% CI 1.01–13.36, p = 0.048). Conclusion: Our analysis reports an association between IBD and PM/DM. Such association could point towards a common pathophysiological background. Further research is needed to further describe the clinical courses and whether a unique therapeutic approach is warranted.

Authors: Chen Yi-Ming , Chiu Wan-Chun , Chiu Yen-Shuo
Published: November 2022

Inonotus obliquus (IO) is used as functional food to treat diabetes. This study investigated the effect of IO supplementation on body composition in relation to changes in energy expenditure and exercise performance. Male Institute of Cancer Research mice were divided into four groups (n = 8 per group) and orally administered IO once daily for 6 wk at 0 (vehicle), 824 (IO-1×), 1648 (IO-2×), and 2472 mg/kg (IO-3×). IO supplementation increased muscle volume, exhaustive treadmill time, and glycogen storage in mice. Serum free fatty acid levels after acute exercise improved in the IO supplementation group, which exhibited changes in energy expenditure through the peroxisome proliferator-activated receptor (PPAR) pathway. RNA sequencing revealed significantly increased PPAR signaling; phenylalanine, ascorbate, aldarate, and cholesterol metabolism; chemical carcinogenesis; and ergosterol biosynthesis in the IO group compared with the vehicle group. Thus, IO supplements as nutraceuticals have a positive effect on lipid transport and exercise performance. In addition, this study was only IO supplementation without training-related procedures.
Simulation as a Tool for Understanding Experimental Observations—Ion Beam Extraction from an ECRIS
Authors: Spädtke Peter
Published: November 2022

A model for the simulation of ion beam extraction from an electron-cyclotron resonance ion source is proposed. It is based on the simple fact that charged particles follow magnetic field lines. Therefore, magnetic field lines are used to generate initial conditions for ray-tracing. This model reproduces in simulation experimentally obtained results. The importance of correlations in phase-space caused by the magnetic field is shown in the simulation. This model also describes the physics of space-charge and its compensation in the extracted (fast) ion beam by low-energy electrons. Simulation provides the possibility to test theoretical assumptions, as well as to optimize technical designs.

Published: November 2022

A novel piezoelectric fiber sensor based on polyvinylidene fluoride piezoelectric (PVDF) doped with graphene is presented. The near-field electrospinning technology was used for developing the sensor. The uniform experimental design method was introduced to determine the ranges of experimental parameters, including the applied voltage, the drum speed range, the graphene doping ratios from 0% to 11 wt% in PVDF solution, and the electrode gap. By experimental results, the conductivities of PVDF solutions with different doping ratios of graphene increased from 19.6 μS/cm to 115.8 μS/cm. Tapping tests were performed to measure the voltages and currents produced by the piezoelectric fibers. The maximum output voltage was 4.56 V at 5 wt% graphene doping ratio in PVDF fibers, which was 11.54 times that of the pure PVDF sensors. Moreover, mechanical properties of the proposed sensor were measured. Motion intention and swallowing test, such as saliva-swallowing and eating, were carried out. When the subject spoke normally, the output voltage of the sensor was between 0.2 and 0.4 V, approximately. Furthermore, when the subject drank water and ate food, the output voltage of the sensor was between 0.5 and 1 V, approximately. The proposed sensor could be used to detect signals of the human body and serve as a wearable device, allowing for more diagnosis and medical treatment.
Analysis and Accuracy Improvement of UWB-TDoA-Based Indoor Positioning System

Published: November 2022

Positioning systems are used in a wide range of applications which require determining the position of an object in space, such as locating and tracking assets, people and goods; assisting navigation systems; and mapping. Indoor Positioning Systems (IPSs) are used where satellite and other outdoor positioning technologies lack precision or fail. Ultra-WideBand (UWB) technology is especially suitable for an IPS, as it operates under high data transfer rates over short distances and at low power densities, although signals tend to be disrupted by various objects. This paper presents a comprehensive study of the precision, failure, and accuracy of 2D IPSs based on UWB technology and a pseudo-range multilateration algorithm using Time Difference of Arrival (TDoA) signals. As a case study, the positioning of a 4×4m2 area, four anchors (transceivers), and one tag (receiver) are considered using bitcraze’s Loco Positioning System. A Cramér–Rao Lower Bound analysis identifies the convex hull of the anchors as the region with highest precision, taking into account the anisotropic radiation pattern of the anchors’ antennas as opposed to ideal signal distributions, while bifurcation envelopes containing the anchors are defined to bound the regions in which the IPS is predicted to fail. This allows the formulation of a so-called flyable area, defined as the intersection between the convex hull and the region outside the bifurcation envelopes. Finally, the static bias is measured after applying a built-in Extended Kalman Filter (EKF) and mapped using a Radial Basis Function Network (RBFN). A debiasing filter is then developed to improve the accuracy. Findings and developments are experimentally validated, with the IPS observed to fail near the anchors, precision around ±3cm, and accuracy improved by about 15cm for static and 5cm for dynamic measurements, on average.
Investigations of Hydrodynamic Force Generated on the Rotating Cylinder Implemented as a Bow Rudder on a Large-Scale Ship Model
Authors: Abramowicz-Gerigk Teresa , Burciu Zbigniew
Published: November 2022

This paper presents experimental studies of the force generated on the rotating cylinder implemented as a bow rudder on a large-scale ship model. The research focused on the maneuverability of the unit equipped with a rotating cylinder (RC) in the front part of the model and its future use as a steering device on small draft river barges. The study presented in this paper is a continuation of the research carried out using the small physical model of a river push train in 1:20 geometric scale equipped with two bow RCs and open water tests of separated rotating cylinders carried out in a flume tank. The experimental test setup with RC installed on the model in 1:24 geometric scale allowed to compare the parameters of standard maneuvers performed with the use of RC and without it. The proposed method based on the measurement of the ship model trajectory during maneuvers allowed to compare the hydrodynamic steering force generated by RC with the steering force generated by the conventional stern spade rudder. The results of the experiments compared with empirical models show a similar trend. RC dynamics was tested for rotational speeds up to 570 RPM (revolutions per minute) and ship model velocity up to 1 m/s. The rotating cylinder generated velocity field is presented and phenomena influencing the generated hydrodynamic force are discussed.
Strain Gauge Measuring System for Subsensory Micromotions Analysis as an Element of a Hybrid Human–Machine Interface
Authors: Bureneva Olga , Safyannikov Nikolay
Published: November 2022

The human central nervous system is the integrative basis for the functioning of the organism. The basis of such integration is provided by the fact that the same neurons are involved in various sets of sensory, cognitive, and motor functions. Therefore, the analysis of one set of integrative system components makes it possible to draw conclusions about the state and efficiency of the other components. Thus, to evaluate a person’s cognitive properties, we can assess their involuntary motor acts, i.e., a person’s subsensory reactions. To measure the parameters of involuntary motor acts, we have developed a strain gauge measuring system. This system provides measurement and estimation of the parameters of involuntary movements against the background of voluntary isometric efforts. The article presents the architecture of the system and shows the organization of the primary signal processing in analog form, in particular the separation of the signal taken from the strain-gauge sensor into frequency and smoothly varying components by averaging and subtracting the analog signals. This transfer to analog form simplifies the implementation of the digital part of the measuring system and allowed for minimizing the response time of the system while displaying the isometric forces in the visual feedback channel. The article describes the realization of the system elements and shows the results of its experimental research.
A Review on Tactile Displays for Conventional Laparoscopic Surgery
Authors: Colan Jacinto , Davila Ana , Hasegawa Yasuhisa
Published: November 2022

Laparoscopic surgery (LS) is a minimally invasive technique that offers many advantages over traditional open surgery: it reduces trauma, scarring, and shortens recovery time. However, an important limitation is the loss of tactile sensations. Although some progress has been made in robotic-assisted minimally invasive surgery (RMIS) setups, RMIS is still not widely accessible. This review aims to identify which tactile display technologies have been proposed and experimentally validated for the restoration of tactile sensations during conventional laparoscopic surgical tasks. We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We identified relevant articles published over the past 10 years through a search on Web of science, Scopus, IEEE Xplore Digital, and PubMed repositories. A total of 143 articles met the inclusion criteria and 24 were included in the final review. From the reviewed articles, we classified the proposed tactile displays into two categories based on the use of skin contact: (i) skin tactile displays, which include vibrotactile, skin-indentation, and grip-feedback devices, and (ii) non-contact tactile displays based on visualization tools. This survey aims to contribute to further research in the area of tactile displays for laparoscopic surgery by providing a better understanding of the current state of the art and identifying the remaining challenges.
Comparative Analysis of the Liquid CO2 Washing with Conventional Wash on Firefighters’ Personal Protective Equipment (PPE)
Authors: Girase Arjunsing , Thompson Donald , Ormond Robert Bryan
Published: November 2022

Firefighters are exposed to several potentially carcinogenic fireground contaminants. The current NFPA 1851 washing procedures are less effective in cleaning due to the limited intensity of the washing conditions that are used. The 2020 edition of NFPA 1851 has added limited specialized cleaning for higher efficacy. The liquid carbon dioxide (CO2) laundering technique has gained popularity in recent years due to its availability to remove contaminants and its eco-friendliness. The primary aim of this study is to address the firefighter questions regarding the efficacy of cleaning with liquid CO2 and to compare it with the conventional washing technique. The unused turnout jackets were contaminated with a mixture of fireground contaminants. These turnout jackets were cleaned with conventional NFPA 1851-appoved aqueous washing and a commercially available liquid CO2 method. Post-cleaning samples were analyzed for contamination using pressurized solvent extraction and GC-MS. The liquid CO2 technique demonstrated considerable improvement in washing efficiency compared to the conventional washing.

Published: November 2022

This study investigated the relationship between the severity of pneumonia based on chest CT findings and that of pancreatic steatosis assessed using an automated volumetric measurement of the CT fat volume fraction (CT-FVF) of the pancreas, using unenhanced three-dimensional CT in polymerase chain reaction (PCR)-confirmed COVID-19 patients. The study population consisted of 128 patients with PCR-confirmed COVID-19 infection who underwent CT examinations. The CT-FVF of the pancreas was calculated using a histogram analysis for the isolation of fat-containing voxels in the pancreas. The CT-FVF (%) of the pancreas had a significantly positive correlation with the lung severity score on CT (ρ = 0.549, p < 0.01). CT-FVF (%) of the pancreas in the severe pneumonia group was significantly higher than that of the non-severe pneumonia group (21.7% vs. 7.8%, p < 0.01). The area under the curve of CT-FVF (%) of the pancreas in predicting the severity of pneumonia on CT was calculated to be 0.82, with a sensitivity of 88% and a specificity of 68% at a threshold for the severity score of 12.3. The automated volumetric measurement of the CT-FVF of the pancreas using unenhanced CT can help estimate disease severity in patients with COVID-19 pneumonia based on chest CT findings.
Continuous Gravitational Wave Emissions from Neutron Stars with Pinned Superfluids in the Core
Authors: Haskell Brynmor , Antonelli Marco , Pizzochero Pierre
Published: November 2022

We investigate the effect of a pinned superfluid component on the gravitational wave emissions of a rotating neutron star. The pinning of superfluid vortices to the flux-tubes in the outer core (where the protons are likely to form a type-II superconductor) is a possible mechanism to sustain long-lived and non-axisymmetric neutron currents in the interior, which break the axial symmetry of the unperturbed hydrostatic configuration. We consider pinning-induced perturbations to a stationary corotating configuration and determine the upper limits on the strength of gravitational wave emissions due to the pinning of vortices with a strong toroidal magnetic field of the kind predicted by recent magneto-hydrodynamic simulations of neutron star interiors. We estimate the contributions to gravitational wave emissions from both the mass and current multipole generated by the pinned vorticity in the outer core and find that the mass quadrupole can be large enough for gravitational waves to provide the dominant spindown torque in millisecond pulsars.

The Open Polytechnic of New Zealand, Whitireia and WelTec had the pleasure of co-hosting the 2021 ITP Research Symposium online on 25 and 26 November 2021. The theme for the 2021 symposium was aumangea (resilience), a concept that resonated across the sector through the multiplicities of change and the realities of Covid-19. The event was originally intended to be a kanohi ki te kanohi symposium on site at the Whitireia Campus in Porirua, but as with many conferences and symposia, Covid-19 measures saw it being transformed into a totally online affair. We were humbled to have hosted over 300 delegates and just over 130 abstracts from experienced, emerging and new researchers from diverse discipline areas. The presenters were geographically dispersed across Aotearoa, from the Far North all the way to the Deep South, but committed in their enthusiasm for and appreciation of research even during a worldwide pandemic, which is a true testimony of the ‘resilience’ of our researchers across the sector during testing times. It was also great to see strong representation of researchers particularly from EIT, Toi Ohomai, Unitec and MIT, and the hosting institutes, among others.

The strict nationwide Covid-19 lockdown that began in March 2020 in Aotearoa New Zealand required staff from tertiary education institutions to immediately adapt and move their teaching and professional activities online, as well as maintain social contact remotely. The aim of our study was to explore the impact of the lockdown and restrictions on working life and personal wellbeing for staff at five Institutes of Technology and Polytechnics (ITPs) across Te Pūkenga national network. Participants were invited to complete an online survey at five time points, corresponding to different alert levels and decreasing social restrictions. They responded to questions about changes to work and personal life, activities to maintain wellbeing, adequacy and trustworthiness of information sources, and provided qualitative comment. Overall, 2250 responses were collected from 1240 individuals over the five time points. They show that participants made higher levels of adjustments in their working lives than in their personal lives or their efforts to maintain social contact. Levels of adjustment decreased over time, despite an increase in alert level (increased social restrictions) in September 2020. Attention to wellbeing also dropped off over time, with an increasing proportion of staff becoming at risk of poor wellbeing (below the cut-off of the WHO-5 depression index). Qualitative comments show innovative and creative ways of maintaining wellbeing despite the requirements for considerable adjustments to participants’ daily working and personal lives.
Marae Ora, Kāinga Ora: A Marae-Led Response to Covid-19
Authors: Lee-Morgan Jenny , Penetito Kim , Eruera Ngahuia
Published: November 2022

Marae Ora, Kāinga Ora (MOKO) is a marae-led community development and wellbeing research project. Lee-Morgan et al. (2021) explain this three-year research project, stating: “MOKO investigates the potential of five marae to strengthen their provision of kāinga (village, settlement) in the contemporary urban context of South Auckland” (p. 2). Using a Kaupapa Māori (KM) approach to Community Based Participatory Research (CBPR), this project explores the ancient Indigenous innovation of marae (both a spiritual and physical location with a socio-cultural setting for Māori to be immersed in a cultural context) and kāinga to understand and co-create new culturally based initiatives and support the activation of community development and wellbeing initiatives. While marae are highly valued by Māori communities as being critical to cultural sustainability and are recognised by government agencies as important community providers, there is a dearth of research about how contemporary urban marae operate and how they can work with, and for, communities (Kawharu, 2014; Tapsell, 2002; Thornley et al., 2015). The MOKO research aim is to enable marae to explore their potential role within their communities, to develop their own interpretation and opportunities for kāinga. These insights influence opportunities to partner with external agencies and services to achieve greater outcomes and collaborative advantages for whānau (family group) and community wellbeing, alongside marae. In brief, the MOKO project is focused on the intergenerational sustainability of the knowledge systems and replenishment of resources inherent within marae, our natural environment and kāinga ora.
Resilience in Daily Routines for Children with Autism
Authors: Afrin Tahera
Published: November 2022

Resilience for children with special needs is often discussed in terms of the families concerned rather than the children themselves. This article reports on a current study that aims to analyse sections of daily routines for children with autism, and to find subsequent examples of resilience that the children show. Under a qualitative research framework, the data is derived from a case study supported by a literature review. The literature review was conducted first to find out existing information that might be useful by parents and teachers to understand resilience of tamariki with autism. Relevant journal articles available in the EBESCO database within the time frame of 2000–2021 were looked at. An integrative review process was applied to navigate answers aligned with the research question. For the case study, the data were anecdotal records, of a child diagnosed with severe autism at the age of three. Anecdotes were from three years after the diagnosis, experienced by the author. The daily routine was divided into regular activities during the periods of morning, afternoon and night, both at home and in an early-childhood setting. The literature review revealed that meal time, toileting, play and transition are the aspects of daily routine that have been studied. However, the findings of these studies were very limited in terms of usefulness to teachers and parents due to their quantitative nature. The case study highlights common trends of resilience in the aspects of a day for a child with autism, while acknowledging differences that prevail. Strands of Te Whāriki, the Aotearoa New Zealand early-childhood curriculum, were used as a framework to analyse data for scaffolding the thoughts and mahi (work) of the early-childhood kaiako (teachers). The study proposes an extended version to include other cases, using social media networks.
Systematic Literature Review of Perspective-Taking in Social Exchanges: Implications for Management and Leadership
Authors: Tuazon Gerson Francis
Published: November 2022

Contemporary research in the area of perspective-taking in the workplace has begun to challenge our view of how it is currently conceptualised and measured. Whereas individual-level perspective-taking was initially assumed to be a predominantly cognitive process, recent empirical work has documented the complexity of perspective-taking and scholars are starting to acknowledge that perspective-taking should not be considered in subjective isolation but in conjunction with sociocultural, affective, and organisational practices. As such, this paper provides an extensive look at perspectivetaking within the context of social-exchange theory through a systematic review methodology. Three core research themes are found within perspective-taking literature: (a) emotional reconfiguration; (b) cognitive reconstitution; and (c) social and organisational familiarisation. These research themes are linked with arguments derived from leader–member exchange (LMX) theory to advance a framework of how perspective-taking may affect social-exchange relationships and consequent organisational outcomes.

Authors: Zanardi Maria Cecília , Oliveira Thales D Monea , Celestino Claudia Celeste
Published: November 2022

The aim of this paper is to validate the analytical propagator through simulations comparing the results with the real data and to optimize the work's source code so that it is processed faster. This work analyzes the use of the quadrupole model in the Earth's magnetic field when an analytical propagator calculates eddy current and residual magnetic torques in spin-stabilized satellites. For that, the components of the gravity gradient torque, the solar radiation torque and aerodynamics torque are also included. The simulations are carried out for a predetermined period and use data from the SCD1 Brazilian satellite, provided by the National Institute for Space Research (INPE). The results are then compared with the real data to validate the propagator. The propagator with the quadrupole model is called GSAMQ and uses the mean deviations of the magnitude of the spin velocity, and the angles of right ascension and declination of the spin axis as evaluation parameters. A statistical approach is included in this analysis and shows the model's accuracy.

Objective: To study the evolution of approaches to surgical treatment in patients with open abdominal trauma.Material and methods: The results of surgical treatment of 141 patients with open abdominal trauma at the age of 32.6 ± 7.3 years have been studied. In the main group of 73 patients, surgical tactics have been determined according to the results of the Focused Assessment with Sonography for Trauma (FAST) protocol and diagnostic video laparoscopy. In the control group of 68 patients, indications for laparotomy have been presented based on the proven fact of a penetrating wound in the abdominal cavity.Results: In patients with unstable hemodynamics and signs of peritonitis there is no need for additional verification of the damage nature. In these cases, an emergency laparotomy is justified. In debatable cases diagnostic video laparoscopy should be the method of choice for the diagnosis. In 19 (27.9%) patients in the control group with the proven fact of a an abdominal penetrating wound during primary surgical treatment (PST), no injuries were detected during the examination of the abdominal organs and the laparotomy was exploratory.Conclusion: A rational approach to assessment of the injuries severity using the FAST protocol and diagnostic video laparoscopy in patients of the main group made it possible to completely avoid exploratory laparotomy and increase the proportion of minimally invasive interventions to 50–70%. The accuracy of laparoscopic diagnostics was 98%.

Relevance: Venous thromboembolic complications are a formidable condition with a high mortality risk, that is rather common in the practice of a physician of any specialty. Therefore, timely diagnosis and correct management of patients with thromboembolic complications are key to a favorable outcome of the disease. An urgent problem for science nowadays is the search and development of diagnostic approaches that give a complete description of a thrombotic event. One of these characteristics is the determination of the age of thrombosis; it is a clear understanding of this criterion that makes it possible to choose a successful treatment strategy for patients with similar complications.Aim of study: To date, the assessment of the age of a thrombus is based mainly on the patient’s anamnestic data, which do not always correspond to the real situation, and imaging techniques based on indirect signs. Therefore, the ineffectiveness of therapy for the described conditions in some cases can be explained by an underestimation of the age of the thrombus. The development of scientific research in this direction seems promising and can lead to an improvement in the results of treatment of patients suffering from venous thromboembolic complications. This article is a review of the methods for thrombus age determination presented in the literature.

O MITO RELIGIOSO COMO O DISCURSO ESPECULATIVO NO SEU CONTEXTO SOCIAL CONTEMPORÂNEO
Authors: Teixeira Rodrigo Lima
Published: November 2022

O mito é uma história contada pelo o homem antigo no tempo majestoso, onde se tenta responder questões que não há respostas, e especulações acerca de como foi criado o mundo, e de como o homem veio a existir, de como a morte veio ao mundo, e como foram construídas as sociedades onde hoje vivemos. Na esfera religiosa, o mito é muito importante, por que ele explica aquilo que não tem explicação, e dá caminho para representatividades morais e culturais, e nisso, o mito religioso tem sua importância no contexto social, pois ele ensina uma sociedade a caminhar sem medo especulando a existência do ser, e explicações mitológicas que podem dar parâmetros significativos dentro do contexto social religioso para a exploração destes mistérios. Assim, o mito religioso nestas concepções têm propriedades psicológicas de alívio das aflições inerentes da vida, e respostas para uma sociedade contemporânea que muitas das vezes provoca vazios existenciais no ser, e cria expectativas e respostas a perguntas que não tem respostas. Neste sentido, foi apresentada uma analise de forma bibliográfica, onde foi utilizados autores das ciências socais que estudaram o mito religioso como uma estrutura social sistêmica, e como discurso especulativo, e o a analise de forma indutiva que estuda o objeto particular para depois verifica as formas gerais objetivais.

Global South Feminist Theology in the Public Sphere: An Alternative Space to Strive for Women’s Full Humanity
Authors: Fyffe - PTS Anne
Published: November 2022

This paper seeks to explore the subject of global South feminist theology in the public sphere. It attempts to engage the questions of what feminist theology in the global South looks like in the public realm and how it addresses public issues, particularly those that affect women. This will be achieved through a discussion of feminist theology in Latin America and Asia. As will be argued in this paper, feminist theology in the global South is, like all theology, contextual. It is also inherently public and intersectional. As women experience oppression, discrimination, and injustice in various forms in the global South and around the world, they are denied their full humanity. Given the contextual, intersectional, and public nature of feminist theology in the global South, its engagement in the public sphere creates an alternative space for dialogue and action as women strive toward full humanity in the local and global contexts.

Authors: Oliveira Souza Everson de
Published: November 2022

Em uma análise sobre as religões percebe-se que existem regras que regulamentam, regras essas que são identificadas como usos e costumes dos seus seguidores. Com relação a esses usos e costumes que são colocados em prática por seus seguidores, é possível perceber diversas mudanças de posicionamento de defesa desses ao longo do tempo, inclusive dentro da Assembleia de Deus. A Assembleia de Deus tem experimentado um grande crescimento desde sua origem no Belém do Pará, quando foi fundada pelos missionários suécos Daniel Berg e Gunnar Vingren, e, ao longo dos anos foram muito os debate sobre a imposição dos usos e costumes nos membros desta. Usos e costumes que se originaram com influências por meio de experiências vividas nos lugares por onde os missionários passaram e que hoje alguns ainda permanecem, outros desapareceram e muitos outros já surgiram. O artigo apresenta uma análise do que é usos e costumes religiosos, da origem da Assembleia de Deus e de seus usos e costumes.
