Beamforming Applied to Ultrasound Analysis in Detection of Bearing Defects
Authors: Verellen Thomas , Verbelen Florian , Stockman Kurt , Steckel Jan
Published: October 2021

The bearings of rotating machinery often fail, leading to unforeseen downtime of large machines in industrial plants. Therefore, condition monitoring can be a powerful tool to aid in the quick identification of these faults and make it possible to plan maintenance before the fault becomes too drastic, reducing downtime and cost. Predictive maintenance is often based on information gathered from accelerometers. However, these sensors are contact-based, making them less attractive for use in an industrial plant and more prone to breakage. In this paper, condition monitoring based on ultrasound is researched, where non-invasive sensors are used to record the noise originating from different defects of the Machinery Fault Simulator. The acoustic data are recorded using a sparse microphone array in a lab environment. The same array was used to record real spatial noise in a fully operational plant which was later added to the acoustic data containing the different defects with a variety of Signal To Noise ratios. In this paper, we compare the classification results of the noisy acoustic data of only one microphone to the beamformed acoustic data. We do this to investigate how beamforming could improve the classification process in an ultrasound condition-monitoring application in a real industrial plant.
Assessment of SMA Electrical Resistance Change during Cyclic Stretching with Small Elongation
Authors: Sławski Sebastian , Kciuk Marek , Klein Wojciech
Published: October 2021

In this article, changes in NiTi alloy (Flexinol) electrical resistance during cyclic stretching with small elongation were investigated. A dedicated test stand consisting of motorized vertical test stand, force gauge, and electric resistance measuring device with an accuracy of 0.006 Ω was developed. A dedicated control algorithm was developed using LabVIEW software. Changes in electrical resistance were investigated for the 0.1 mm Flexinol wire with length of 120 mm. Testing was performed in the elongation range between 0.25% and 1.5% in martensite phase. Tested samples were subjected to 30 stretching cycles with a movement speed of 10 mm/min. Obtained results show that the cyclic stretching of Flexinol wire reduces its electrical resistance with each stretching cycle. Moreover, it was noted that changes in Flexinol electrical resistance during cycling stretching depend on the assumed elongation and number of the already performed stretching cycles. The observed electrical resistance change decreases with each stretching cycle. Thus, the observed changes are greater during the first stretching cycles. For elongations exceeding 1%, the Flexinol electrical resistance in the first stretching cycle increases. In each subsequent cycle, electrical resistance decreases, as in the case of the smallest value of assumed elongation. In almost all tested cases (except in the case with 1.5% of assumed elongation), Flexinol electrical resistance after 30 stretching cycles was smaller than before the test.
Determination of Chewing Count from Video Recordings Using Discrete Wavelet Decomposition and Low Pass Filtration
Authors: Alshboul Sana , Fraiwan Mohammad
Published: October 2021

Several studies have shown the importance of proper chewing and the effect of chewing speed on the human health in terms of caloric intake and even cognitive functions. This study aims at designing algorithms for determining the chew count from video recordings of subjects consuming food items. A novel algorithm based on image and signal processing techniques has been developed to continuously capture the area of interest from the video clips, determine facial landmarks, generate the chewing signal, and process the signal with two methods: low pass filter, and discrete wavelet decomposition. Peak detection was used to determine the chew count from the output of the processed chewing signal. The system was tested using recordings from 100 subjects at three different chewing speeds (i.e., slow, normal, and fast) without any constraints on gender, skin color, facial hair, or ambience. The low pass filter algorithm achieved the best mean absolute percentage error of 6.48%, 7.76%, and 8.38% for the slow, normal, and fast chewing speeds, respectively. The performance was also evaluated using the Bland-Altman plot, which showed that most of the points lie within the lines of agreement. However, the algorithm needs improvement for faster chewing, but it surpasses the performance of the relevant literature. This research provides a reliable and accurate method for determining the chew count. The proposed methods facilitate the study of the chewing behavior in natural settings without any cumbersome hardware that may affect the results. This work can facilitate research into chewing behavior while using smart devices.

Authors: Abdelwahab Haneen , Ebrahimi Amir , Tovar-Lopez Francisco J. , Beziuk Grzegorz , Ghorbani Kamran
Published: October 2021

In this paper, a very high sensitivity microwave-based planar microfluidic sensor is presented. Sensitivity enhancement is achieved and described theoretically and experimentally by eliminating any extra parasitic capacitance not contributing to the sensing mechanism. The sensor consists of a microstrip transmission line loaded with a series connected shunt LC resonator. A microfluidic channel is attached to the area of the highest electric field concentration. The electric field distribution and, therefore, the resonance characteristics are modified by applying microfluidic dielectric samples to the sensing area. The sensor performance and working principle are described through a circuit model analysis. A device prototype is fabricated, and experimental measurements using water/ethanol and water/methanol solutions are presented for validation of the sensing mathematical model.
Using Social Signals to Predict Shoplifting: A Transparent Approach to a Sensitive Activity Analysis Problem
Authors: Reid Shane , Coleman Sonya , Vance Philip , Kerr Dermot , O’Neill Siobhan
Published: October 2021

Retail shoplifting is one of the most prevalent forms of theft and has accounted for over one billion GBP in losses for UK retailers in 2018. An automated approach to detecting behaviours associated with shoplifting using surveillance footage could help reduce these losses. Until recently, most state-of-the-art vision-based approaches to this problem have relied heavily on the use of black box deep learning models. While these models have been shown to achieve very high accuracy, this lack of understanding on how decisions are made raises concerns about potential bias in the models. This limits the ability of retailers to implement these solutions, as several high-profile legal cases have recently ruled that evidence taken from these black box methods is inadmissible in court. There is an urgent need to develop models which can achieve high accuracy while providing the necessary transparency. One way to alleviate this problem is through the use of social signal processing to add a layer of understanding in the development of transparent models for this task. To this end, we present a social signal processing model for the problem of shoplifting prediction which has been trained and validated using a novel dataset of manually annotated shoplifting videos. The resulting model provides a high degree of understanding and achieves accuracy comparable with current state of the art black box methods.

Authors: Song Kyoungho , Son Hansol , Park Suwon , Lee Jonghan , Jang Jungsik , Lee Mijung , Choi Hyun-joo
Published: October 2021

In this study, 3D-printable flexible piezoresistive composites containing various amounts of cilia-like hybrid fillers were developed. In the hybrid fillers, micro-scale Cu particles with a 0D structure may allow them to easily disperse into the flexible TPU matrix. Furthermore, nanoscale multi-walled carbon nanotubes (MWCNTs) with a high aspect ratio, present on the surface of the Cu particles, form an electrical network when the polymer matrix is strained, thus providing good piezoresistive performance as well as good flowability of the composite materials. With an optimal hybrid filler content (17.5 vol.%), the 3D-printed piezoresistive composite exhibits a gauge factor of 6.04, strain range of over 20%, and durability of over 100 cycles. These results highlight the potential applications of piezoresistive pressure sensors for health monitoring, touch sensors, and electronic skin.

Authors: Saia Roberto , Podda Alessandro Sebastian , Pompianu Livio , Reforgiato Recupero Diego , Fenu Gianni
Published: October 2021

In recent decades, modern societies are experiencing an increasing adoption of interconnected smart devices. This revolution involves not only canonical devices such as smartphones and tablets, but also simple objects like light bulbs. Named the Internet of Things (IoT), this ever-growing scenario offers enormous opportunities in many areas of modern society, especially if joined by other emerging technologies such as, for example, the blockchain. Indeed, the latter allows users to certify transactions publicly, without relying on central authorities or intermediaries. This work aims to exploit the scenario above by proposing a novel blockchain-based distributed paradigm to secure localization services, here named the Internet of Entities (IoE). It represents a mechanism for the reliable localization of people and things, and it exploits the increasing number of existing wireless devices and blockchain-based distributed ledger technologies. Moreover, unlike most of the canonical localization approaches, it is strongly oriented towards the protection of the users’ privacy. Finally, its implementation requires minimal efforts since it employs the existing infrastructures and devices, thus giving life to a new and wide data environment, exploitable in many domains, such as e-health, smart cities, and smart mobility.
A Security Management and Control Solution of Smart Park Based on Sensor Networks
Authors: Zhao Yue , Tian Bo , Niu Yiru , Zhang Hao , Yi Zhongqiang , Zeng Ruiqi
Published: October 2021

As a typical application of sensor networks, there exist many information security problems in smart parks, such as confusion of personnel access, lack of security management, disorderly data flow, insufficient collection of audit evidence, and so on. Aiming at the scenario of personnel and equipment moving in different areas of smart parks, the paper proposes a joint authorization and dynamic access control mechanism, which can provide unified identity management services, access control services, and policy management services, and effectively solve the problem of multi-authorization in user identity and authority management. The license negotiation interaction protocol is designed to prevent common network attack threats in the process of identity authentication and authority management. In order to realize the tamper-proof storage of personnel and equipment movement trajectory, the paper also designs a movement trajectory traceability protocol based on a Merkle tree, which solves the problems of internal personnel malicious attack, trusted third-party dependency bottleneck, high overheads of tracking algorithms, and so on. The experimental results show that compared with the current security control mechanisms for sensor networks, the joint authorization, and dynamic access control mechanism can support multi-party authorization and traceability, while the overhead it generates in initialization, encryption, decryption, and key generation steps are basically the same as other mechanisms do.
“Why Can’t We?” Disinformation and Right to Self-Determination. The Catalan Conflict on Twitter
Authors: Llorca-Asensi Elena , Sánchez Díaz Alexander , Fabregat-Cabrera Maria-Elena , Ruiz-Callado Raúl
Published: October 2021

Disinformation does not always take the form of a fake news item, it also appears in much less evident formats which are subtly filtered into public opinion, thus making its detection more difficult. A method is proposed in this paper to address the study of “widespread” disinformation by combining social science methods with artificial intelligence and text mining. The case study chosen was the expression “right of self-determination” as a generator of disinformation within the context of the Catalan independence process. The main work hypothesis was that the (intentional or unintentional) confusion around the meaning and scope of this right has become widely extended within the population, generating negative emotions which favour social polarisation. The method utilised had three stages: (1) Description of the disinformation elements surrounding the term with the help of experts; (2) Detection of these elements within a corpus of tweets; (3) Identification of the emotions expressed in the corpus. The results show that the disinformation described by experts clearly dominates the conversation about “self-determination” on Twitter and is associated with a highly negative emotional load in which contempt, hatred, and frustration prevail.
Understanding Equity of Access in Engineering Education Making Spaces
Authors: Villanueva Alarcón Idalis , Downey Robert Jamaal , Nadelson Louis , Choi Yoon Ha , Bouwma-Gearhart Jana , Tanoue Chaz
Published: October 2021

The goal of our exploratory study was to examine how management and staff in engineering education making spaces are enacting equitable access amongst their users (e.g., students). We examined six different making space types categorized by Wilczynsky’s and Hoover’s classification of academic makerspaces, which considered scope, accessibility, users, footprint (size), and management and staffing. We reviewed research memos and transcripts of interviews of university makerspace staff, student staff, and leaders/administrators during two separate visits to these places that took place between 2017 and 2019. We inductively and deductively coded the data, and the findings suggested that equity of access was situational and contextual. From the results, we identified four additional considerations needed to ensure equitable access for engineering education making spaces: (a) spaces designed and operated for multiple points of student entry; (b) spaces operated to facilitate effective student making processes and pathways; (c) threats to expanded access: burdens and consequences; and (d) elevating student membership and equity through a culture of belonging. Together, the findings point toward a need for developing a more nuanced understanding of the concept of access that far supersedes a flattened definition of access to just space, equipment, and cost.
A Deep Learning Method for Monitoring Vehicle Energy Consumption with GPS Data
Authors: Ko Kwangho , Lee Tongwon , Jeong Seunghyun
Published: October 2021

A monitoring method for energy consumption of vehicles is proposed in the study. It is necessary to have parameters estimating fuel economy with GPS data obtained while driving in the proposed method. The parameters are trained by fuel consumption data measured with a data logger for the reference cars. The data logger is equipped with a GPS sensor and OBD connection capability. The GPS sensor measures vehicle speed, acceleration rate and road gradient. The OBD connector gathers the fuel consumption signaled from OBD port built in the car. The parameters are trained by a 5-layer deep-learning construction with input data (speed, acceleration, gradient) and labels (fuel consumption data) in the typical classification approach. The number of labels is about 6–8 and the number of neurons for hidden layers increases in proportionate to the label numbers. There are about 160–200 parameters. The parameters are calibrated to consider the wide range of fuel efficiency and deterioration degree in age for various test cars. The calibration factor is made from the certified fuel economy and model year taken from the car registration form. The error range of the estimated fuel economy from the measured value is about −6% to +7% for the eight test cars. It is accurate enough to capture the vehicle dynamics for using the input and output data in point-to-point classification style for training steps. Further, it is simple enough to hit fuel economy of the other test cars because fuel economy is a kind of averaged value of fuel consumption for the time period or driven distance for monitoring steps. You can predict or monitor energy consumption for any vehicle with the GPS-measured speed/acceleration/gradient data by the pre-trained parameters and calibration factors of the reference vehicles according to fuel types such as gasoline, diesel and electric. The proposed method requires just a GPS sensor that is cheap and common, and the calculating procedure is so simple that you can monitor energy consumption of various vehicles in real-time with ease. However, it does not consider weight, weather and auxiliary changes and these effects will be addressed in the future works with a monitoring service system under preparation.

Authors: Semple John C. , Zhang Jie , Cook Rachel E. , Suripto Bambang Agus
Published: October 2021

Chromosome numbers are reported here for the first time from 117 individuals of Solidago rugosa and S. fistulosa. Including 178 previously published reports for the two species plus S. latissimifolia, chromosome numbers have been determined from 295 individuals from 269 locations. Only diploids (2n = 18) were found throughout the range of S. fistulosa on the coastal plain in the eastern U.S.A. (44 counts). Diploids (2n = 18) were found in the northern portion of the range of S. latissimifolia, and tetraploids (2n = 36) and hexaploids (2n = 54) were found in the central and southern portions of the range (nine counts in total). Diploids (2n = 18) were found throughout the range of S. rugosa in much of eastern North America in four of the five varieties (northern var. rugosa, var. sphagnophila; southern var. aspera and var. celtidifolia). Tetraploids (2n = 36) were found in all four of these varieties and exclusively in var. cronquistiana in the southern high Appalachian Mountains. Hexaploids (2n = 54) were found in var. sphagnophila at scattered locations. One possible hexaploid in var. rugosa was found in the Allegheny Mountains. The diversity in ploidy levels was independent of the size of the range and the diversity of growing conditions among the three species of S. subsect. Venosae.
Higher Regularity, Inverse and Polyadic Semigroups
Authors: Duplij Steven
Published: October 2021

We generalize the regularity concept for semigroups in two ways simultaneously: to higher regularity and to higher arity. We show that the one-relational and multi-relational formulations of higher regularity do not coincide, and each element has several inverses. The higher idempotents are introduced, and their commutation leads to unique inverses in the multi-relational formulation, and then further to the higher inverse semigroups. For polyadic semigroups we introduce several types of higher regularity which satisfy the arity invariance principle as introduced: the expressions should not depend of the numerical arity values, which allows us to provide natural and correct binary limits. In the first definition no idempotents can be defined, analogously to the binary semigroups, and therefore the uniqueness of inverses can be governed by shifts. In the second definition called sandwich higher regularity, we are able to introduce the higher polyadic idempotents, but their commutation does not provide uniqueness of inverses, because of the middle terms in the higher polyadic regularity conditions. Finally, we introduce the sandwich higher polyadic regularity with generalized idempotents.

Published: October 2021

The COVID-19 pandemic is still posing a devastating threat to social life and economics. Despite the modest decrease in the number of cases during September–November 2020, the number of active cases is on the rise again. This increase was associated with the emergence and spread of the new SARS-CoV-2 variants of concern (VOCs), such as the U.K. (B1.1.7), South Africa (B1.351), Brazil (P1), and Indian (B1.617.2) strains. The rapid spread of these new variants has raised concerns about the multiple waves of infections and the effectiveness of available vaccines. In this review, we discuss SARS-CoV-2 reinfection rates in previously infected and vaccinated individuals in relation to humoral responses. Overall, a limited number of reinfection cases have been reported worldwide, suggesting long protective immunity. Most reinfected patients were asymptomatic during the second episode of infection. Reinfection was attributed to several viral and/or host factors, including (i) underlying immunological comorbidities; (ii) low antibody titers due to the primary infection or vaccination; (iii) rapid decline in antibody response after infection or vaccination; and (iv) reinfection with a different SARS-CoV-2 variant/lineage. Infections after vaccination were also reported on several occasions, but mostly associated with mild or no symptoms. Overall, findings suggest that infection- and vaccine-induced immunity would protect from severe illness, with the vaccine being effective against most VOCs.
Effectiveness of Mandatory and Incentive-Based Routine Childhood Immunization Programs in Europe: A Systematic Review of the Literature
Authors: Kuznetsova Lidia , Cortassa Giorgio , Trilla Antoni
Published: October 2021

There is a lack of comprehensive and systematic data and evidence regarding the effectiveness of mandatory and incentive-based vaccination schemes. The results of such programs in some countries have not been adequately studied. A number of countries have recently introduced tightening vaccination measures, and it is important to analyze and assess the results of these programs. The unprecedented situation due to the COVID-19 pandemic and mass vaccination made the topic of the effectiveness of vaccination policies and mandates even more relevant. The aim of the study is to assess childhood vaccination programs implemented in selected countries. The study focuses on initiatives implemented in the European Region of the World Health Organization (WHO). A total of 466 full-text articles were assessed for eligibility, and 26 articles on seven countries were included in the synthesis. Additionally, we obtained and performed an analysis of data on the impact of COVID-19 on vaccine coverage and incidence of vaccine-preventable diseases, and the implementation of vaccine mandates in the selected countries. The evidence collected and analyzed in this review allowed us to conclude that the introduction of children routine vaccination mandates increases vaccine coverage and reduces the incidence of vaccine-preventable diseases when compared to the situation before the introduction of the mandates.

Published: October 2021

The article is devoted to a rare disease of the perianal region — Buschke-Levenshtein tumor. A clinical case and a literature review on the etiology, pathogenesis and experience of treating such tumors are presented. Evidence based sources show that currently there is no generally accepted tactics of managing patients with this pathology. In this regard, each case of treatment of such patients is of not only scientific but also practical interest. In this case, the tactics of staged treatment with the use of high-temperature dissectors and immunocorrection was chosen, which made it possible to achieve a good clinical result without the formation of extensive and long-term non-healing wound defects in the perianal region.

Published: October 2021

Dysfunction of the rectal sphincter is noted in more than 70 % of patients with rectovaginal fistulas (RVF), which require an extremely careful evaluation of the rectal sphincter function both by clinical and instrumental methods. Objective: to study the state of rectal sphincter in patients with rectovaginal fistulas before and after surgical treatment. Materials and methods: in the period from 2012 to 2021 198 patients (age from 20 to 73 years, Me = 35 (30; 45)) were included in the comprehensive study of the rectal sphincter functional state before and after surgical treatment. 106 (53,5 %) cases were recurrent. Traumatic childbirth was the most common cause of RVF (43,9 %). Results: dysfunction of the rectal sphincter is revealed in 154 (77,8 %) patients with rectovaginal fistulas. The etiology of the disease and the recurrent course do not affect the severity of the rectal sphincter functional disorders. Using of a split rectal-vaginal flap do not lead to a worsening of the rectal sphincter function. Conclusion: A significant mismatch between the obtained objective (sphincterometry) and subjective (Wexner scale) data of the rectal sphincter function in patients with rectovaginal fistulas proves the need for sphincterometry in this category of patients. Elimination of rectovaginal fistulas by using a split vaginal-rectal flap is a safe and low-traumatic surgical method.

Tensiones y reformulaciones en torno a las masculinidades en el policial negro en Últimos días de la víctima de José Pablo Feinmann
Authors: Vilariño Andrea , Pérez Ana Laura
Published: October 2021

Últimos días de la víctima es una novela escrita por José Pablo Feinmann en 1979. En general, la novela ha sido leída por la crítica en clave política (Gandolfo, 1986; Lafforgue y Rivera, 1997; Calabrese, 2000; Jacovski, 2011). En este trabajo, nos proponemos aportar otra arista a esa lectura, vinculándola con las relaciones de jerarquía y masculinidad entre los personajes. Al mismo tiempo, intentaremos problematizar la construcción de la masculinidad en el personaje de Mendizábal, ya que se encuentra constantemente tensionada tanto por la relación obsesiva que entabla con su objetivo, Külpe, como por la mirada de su rival, Peña.
Si muero antes de despertar, de Carlos Hugo Christensen: maneras de ser hombre, entre la modalidad del policial y la del noir
Authors: Debussy Pablo
Published: October 2021

Este trabajo analiza el film de Carlos Hugo Christensen Si muero antes de despertar (1952) a partir de la disputa de dos modalidades: la modalidad policial y la del noir. La primera de ellas se vincula con la ley, el orden y las instituciones (familia, escuela, iglesia), mientras que la segunda lo hace en relación con los deseos sexuales prohibidos y la criminalidad. De manera complementaria, se analiza la configuración de diversas masculinidades, que subyacen a dichas modalidades, así como también las zonas de la ciudad y su división geográfica y moral: de un lado, el barrio “cordial”, que incluye la casa paterna y la escuela; del otro, el baldío, el lugar del deseo sexual perverso.
Políticas de la virilidad. Masculinidades en el cine policial y criminal de Carlos Hugo Christensen en Brasil (1960-1970)
Authors: Gil Mariño Cecilia Nuria
Published: October 2021

Durante varias décadas, la crítica nacional brasileña colaboró con la estigmatización de los géneros cinematográficos identificándolos con el imperialismo cultural y diferenciando a sus realizadores entre autores y artesanos. Esto impactó en el desarrollo de una historiografía que privilegió al cine de autor. No obstante, el cine policial, criminal, el terror y sus monstruos constituyen un espacio discursivo privilegiado a la hora de pensar los miedos, las ansiedades y las formas de violencia de una sociedad en relación con las matrices culturales binarias de las imágenes y discursos de lo masculino y lo femenino.

En este sentido, el presente trabajo aborda la filmografía de Carlos Hugo Christensen en Brasil, referente ineludible de los orígenes del género policial en la Argentina, para indagar la potencialidad política de estos objetos de la cultura de masas desde una perspectiva de género. Se buscará analizar las relaciones entre las desestabilizaciones del orden y la ley como institución masculina que se plantean en el género policial y criminal, con las de la heteronormatividad a través de la puesta en escena de subjetividades que desafían o ponen en cuestión las relaciones de poder de las masculinidades.

O livro didático é o recurso mais utilizado no ensino de ciências no Brasil e deve possuir conteúdo claro e coerente descrevendo o universo do aluno. A esquistossomose é uma doença endêmica parasitária de caráter cosmopolita causada pelo helminto Schistosoma mansoni, com altas taxas de prevalência nas regiões tropicais e subtropicais, destacando-se no segundo lugar das parasitoses mais frequentes no mundo. Sendo assim, torna-se imprescindível que os alunos tenham o conhecimento a respeito da esquistossomose de forma clara, visando amplificar as principais medidas profiláticas e identificação da doença. O objetivo do estudo foi avaliar o conteúdo de esquistossomose oferecido por livros do ensino médio de Biologia. Para isto, foi realizada uma busca temática sobre “Esquistossomose” em oito livros de Biologia do 2° ano do ensino médio, sendo três de volume único e cinco de volume 2. Os critérios de análise foram conceitos e definições, desenvolvimento dos conceitos e definições, explicação dos termos desconhecidos, correção científica, adequação a idade mínima, enfoque sanitário, ilustração e tipos de atividades. Os resultados mostraram que os seis livros possuem o conteúdo de “Esquistossomose”, onde em parte evidenciaram a morfologia do parasito, outros autores, focaram em ciclos, meios de transmissão, hospedeiros definitivo e intermediário, medidas profiláticas, entre outros.
Legibility of Pharmaceutical Pictograms
Authors: Pedersen Pia
Published: October 2021

The design of medicinal information in leaflets and labels is often criticized for not meeting patients' needs. For that reason, there is an increasing focus on how the use of pictures, such as pictograms, may benefit patients on their medical journey. However, before a pictogram can be comprehended it must be legible, which may be a challenge when pharmaceutical information has to be conveyed. Within a limited space many visual details need to be included in order to clarify the intended meaning. While we have abundant information about the comprehension of pictograms, we know very little about the legibility - the ability to visually identify objects - of pictograms. By looking at legibility research into pharmaceutical pictograms from a design perspective, this paper demonstrates that legibility is not prioritized either in theory or in practice. In order to proceed with the use and implementation of pictograms in, for example, patient information leaflets and labels, we need to know more about the features that constitute legibility. To create a research foundation, this paper draws on knowledge of visibility and legibility from related domains. This forms the basis of a discussion of the need for future research to focus on legibility issues, amongst others by incorporating design knowledge into experiments.

Published: October 2021

We examined if there is any intrinsically "hard-wired" tendency in the subject's Visual Attention. When asked to spontaneously decide preferences for shape or grouping of shapes, distinct patterns of preference in human test subjects were found. These preferences were consistent among ages older than 20 years adulthood and both genders. These findings could result in broad practical applications ranging from interface designs to visual alerts.
ELEMENTOS PARA DISCUSSÃO DO CONCEITO DE TERRITÓRIO: PERSPECTIVA OPERACIONAL NA ESTRATÉGIA DE SAÚDE DE FAMÍLIA NO BAIRRO DO ENGENHO DO MEIO-RECIFE/PE
Authors: Felix Bastos Priscila
Published: October 2021

As mudanças ocorridas no modelo assistencial do Sistema Único de Saúde foram essenciais para a melhoria na qualidade do atendimento e, neste sentido, a Estratégia de Saúde da Família merece destaque. Esta proporcionou a identificação do paciente a partir de uma base territorial e trouxe consigo uma melhor compreensão a respeito das necessidades locais da população. Diante dos fatos aqui expostos, pretende-se analisar a operacionalização do conceito de território e a territorialização das ações empreendidas na saúde, especificamente, na Estratégia de Saúde da Família estabelecida no bairro do Engenho do Meio, Recife-PE. Para tanto, empreendeu-se um estudo de natureza qualitativa e quantitativa, através de entrevistas semiestruturadas e questionários aplicados com as equipes de profissionais e usuários do Sistema Único de Saúde. A partir da apreciação dos dados foi possível observar que a saúde organiza suas ações em uma base territorial, mas utiliza apenas o critério político administrativo na elaboração dos recortes espaciais onde são desenvolvidas as ações de saúde. Este fato, por sua vez, limita a organização do processo de trabalho, restringindo a possibilidade de melhorias significativas nas ações. Tal fato acaba por dificultar a adequação da rede às reais necessidades dos pacientes.

Nesse sentido, este artigo tem como objetivo analisar a centralidade de Mossoró na rede urbana regional em fins do século XIX e início do século XX, identificando, para tanto, a atração e dispersão dos diferentes fluxos a partir da cidade, que lhe atribui centralidade em temporalidades distintas. A pesquisa possui abordagem na Geografia Histórica Urbana, conforme a demarcação temporal e a condução da análise com ênfase em várias fontes documentais primárias. Conclui-se que desde meados do século XIX, Mossoró constitui-se um importante nó da rede urbana-regional, passando por diversos processos de reestruturação de suas funções urbanas.
