Authors: He Li , Tao Jian’ge , Meng Ping , Chen Dan , Yan Meng , Vasa László
Published: September 2021

Research background: Previous studies on the economic and social development of urban agglomerations mostly focus on a single primacy comparative analysis and efficiency evaluation. Spatial structure differentiation is an important feature of urban agglomeration. The lack of economic and social analysis on the spatial structure makes it impossible to determine the development positioning of each city in the urban agglomeration, which affects the sustainable economic devel-opment ability of these areas.

Purpose of the article: The objective of the article is to analyze the spatial development law and experience of urban agglomeration, this study explores the practice of economic and population spatial structure of city areas in China. For this purpose, CPUA and its central city Zhengzhou was taken as an example, the spatial gradient structure of example was analyzed.

Methods: Using economic and population data of 32 cities in this region, growth pole theory, and pole-axis theory, the economic and population spatial structure of urban agglomeration, the spatial gradient structure of central cities in urban agglomerations were analyzed with the method of cluster about radiation index.

Findings & value added: (1) In the process of the formation of CPUA, the geo-graphical spatial pattern plays a decisive role in economic and social development. This is an experience from developing countries. (2) CPUA presents a gradient development pattern with Zhengzhou as the center, and economic and social development gradually radiates to the metropolitan area, the core development area, and the character development demonstration area. (3) The economic and social gradients of Zhengzhou, the central city, present the hierarchy rules and characteristics which are driven by the Beijing-Guangzhou-Railway axis and the Longhai-Railway axis. (4) The central city of Zhengzhou still presents insufficient primacy in regional development, which shows that Zhengzhou accounts for 6% of the population of the Central Plains Economic Zone and 14% of GDP, and insufficient agglomeration. Different countries at different stages of economic development have different urban agglomeration development models. The conclusions from China provide new decision-making ideas and methods for spatial structure research and development strategy analysis of urban agglomerations.

Published: September 2021

Learning a program is important for all students, not only students from the field of computer science but all fields. Programming languages are different from human communication languages as they have different structural forms. This makes it difficult for beginners especially for non-computer science students to understand the structure of programming languages. Therefore, to learn and understand the programming language more effectively, this article focuses on the important structure in learning a program from the initial stage to the advanced level suitable for non-computer science students. The objective of this article is to suggest important elements that can be assessed on these students which are to measure their understanding as they learn programming languages. The questions proposed to measure students' understanding were based on Bloom's Taxonomy, which covers six levels of understanding. It is hoped that this assessment proposal can act as a guideline for educators in fully focusing on important matters during the teaching and learning process.

Published: September 2021

Gold is known as the most valuable commodity in the world because it is a universal currency recognized by every single bank across the globe. Thus, many people were interested in investing gold since gold market was always steadier compared to other investment (Khamis and Awang, 2020). However, the credibility of gold was questionable due to the changes in gold prices caused by a variety of circumstances (Henriksen, 2018). Hence, information on the inflation of gold prices were needed to understand the trend in order to plan for the future in accordance with international gold price standards. The aim of this study was to identify the trend of Kijang Emas monthly average prices in Malaysia from the year 2010 to 2021, to determine the best fit time series model for Kijang Emas prices in Malaysia and using univariate time series models to forecast Kijang Emas prices in Malaysia. The ARIMA and ARFIMA models were used in this study to model and forecast the prices of gold (Kijang Emas) in Malaysia. Each of the actual monthly Kijang Emas prices for 2021 were found to be within the 95% predicted intervals for both the ARIMA and ARFIMA models. The performances for each model were checked by considering the values of MAE, RMSE and MAPE. From the findings, all the MAE, RMSE and MAPE values showed that the ARFIMA model emerged as the better model in forecasting the Kijang Emas prices in Malaysia compared to the ARIMA model.

Technology has advanced to the point that it can assist people in their daily lives. Human beings may benefit from this development in a variety of ways. Progress in river water monitoring is also one of them. There are many advantages in improving the river water monitoring system. The objective of this project is to develop an automated system for monitoring river water levels and quality with push notification features. Internet of Things (IoT) was implemented in this research by using NodeMCU as a microcontroller to connect both ultrasonic sensors and pH sensors to the Internet. An ultrasonic sensor is used to read the water level, and a pH sensor is used to read the water pH values. The results show the successful output from all of 10 time attempts to obtain more accurate test results. The results will be averaged to be analysed and concluded from the test. All the tests include testing for the accuracy of the ultrasonic sensor, the accuracy of the pH sensor, and the performance of the internet connection using integrated Wi-Fi module in NodeMCU microcontroller. The system test also shows that it performs perfectly with the requirement needed to send the real-time status of the water level, water quality and an alert to the user using the Telegram Bot API. This research can help to increase the level of awareness of the river water monitoring system. This research was done by looking at people's problems in the vicinity of the river area by producing a system tool that helps to monitor the river water in real-time status.

Published: September 2021

Road accidents are incidents that should be avoided. One of the contributing factors of road accidents occurrence is drowsiness while driving due to fatigue. In this project, fatigue and drowsiness of a person can be detected by looking at the eye area. Drowsy situations are dangerous especially when driving a vehicle over long distances. When a person starts to feel drowsy, the eyes will start to blink more frequently. This characteristic can be used to monitor a driver’s fitness level. In this project the Viola-Jones algorithm using MATLAB cascade object detector was used to detect the presence of blinking eyes.  The algorithm is consisted of three phases which are, selection of Haar-like characteristics, integrating a picture into the whole, and Classifiers in a cascading fashion. A number of 29 samples images consisting of the condition fatigue face and non-fatigue face was used. The obtained results obtained were calculated based on the accuracy value of the detected blinking eye. The result shows that both the total Area Under the Curve (AUC) values for faces with fatigue situations and non-fatigue situations are above acceptable values which is 0.5. This indicates both classifications are acceptable and can be used to detect the presence of blinking eyes which represent drowsiness.

The Effect of Laser Shots on Morphological and Optical Properties of Copper Oxide NPs Prepared by Nd-Yag Laser of 1064 nm Wavelengths in Distilled Water
Authors: M Kareem Mahmood
Published: September 2021

This study examines the synthesis of copper oxide nanoparticles (NPs) by using a Q-Switched Nd-Yag (1064 nm) laser on copper foil immersed in Distilled Water (DW). The solution color changed to light green refers to the production of copper oxide NPs. The generated nanoparticles were studied to determine their characteristics as a function of pulse laser shots and the NPs were obtained by taking 500 and 1000 laser pulse shots on Cu target. Thin films deposited on both (glass and silicon) substrates were characterized by X-Ray Diffraction (XRD), Field Emission-Scanning Electron Microscopy (FE-SEM), and Atomic Force Microscopy (AFM) techniques. Later, regarding the colloidal nanoparticles, NPs were instantly characterized by UV-vis spectroscopy and examined by TEM microscopy. The production rate of Cu-NPs concentration in the colloidal solution was measured by atomic absorption spectra type (ICP-OES), which increased by increasing the number of laser shots in the liquid volume. The Energy Dispersion Spectroscopy (EDS) analysis resulted in the presence of copper (Cu) and oxygen (O) elements in the film structure with a nearly stoichiometry ratio. The optical energy gap was decreased to (2.44 eV) with increasing the number of laser shots in the colloidal solution.

Published: September 2021

A young male with β-thalassemia major was implanted with a single-chamber Implantable cardioverter-defibrillator (ICD) for a cardiac arrest due to ventricular fibrillation. He received multiple inappropriate shocks due to atrioventricular nodal re-entrant tachycardia (AVNRT) treated with radiofrequency catheter ablation and then to high-rate atrial tachycardia refractory to amiodarone and not inducible during electrophysiological study. He refused empirical pulmonary vein isolation. Upgrading to biventricular ICD and performing atrioventricular node ablation avoided further inappropriate shocks.
Hand Guiding a Virtual Robot Using a Force Sensor
Authors: Gregor Radovan , Babinec Andrej , Duchoň František , Dobiš Michal
Published: September 2021

The research behind this paper arose out of a need to use an open-source system that enables hand guiding of the robot effector using a force sensor. The paper deals with some existing solutions, including the solution based on the open-source framework Robot Operating System (ROS), in which the built-in motion planner MoveIt is used. The proposed concept of a hand-guiding system utilizes the output of the force–torque sensor mounted at the robot effector to obtain the desired motion, which is thereafter used for planning consequential motion trajectories. Some advantages and disadvantages of the built-in planner are discussed, and then the custom motion planning solution is proposed to overcome the identified drawbacks. Our planning algorithm uses polynomial interpolation and is suitable for continuous replanning of the consequential motion trajectories, which is necessary because the output from the sensor changes due to the hand action during robot motion. The resulting system is verified using a virtual robot in the ROS environment, which acts on the real Optoforce force–torque sensor HEX-70-CE-2000N. Furthermore, the workspace and the motion of the robot are restricted to a greater extent to achieve more realistic simulation.

Published: September 2021

Background: Colorectal mucosal biopsies account for majority of daily practice specimens in the field of gastrointestinal pathology. Most of them were sent for inflammatory bowel disease (IBD) evaluation. Due to broad spectrum of histologic findings and different stage of disease, pathologists often find difficulties on calling out diagnosis of IBD. This study aims to evaluate the adequacy of specimen, clinical characteristics, endoscopy and histologic findings of colorectal biopsies from IBD and non-IBD patients.Method: This cross-sectional study included 49 IBD and 49 non-IBD cases registered in the archives of Anatomical Pathology Department, Cipto Mangunkusumo National Referral Hospital Jakarta in 2019. The samples were evaluated for adequacy of specimen, clinical, endoscopy and histologic findings.Results: Most samples were adult with a slight female predominance. All request forms contained the clinical working diagnosis but only 26.5% and 20.4% of them provided clinical history and endoscopy findings. During histology evaluation, 59.2% of the specimen was considered sub-optimal. The most common histologic findings in both IBD and non-IBD groups were diffuse lymphoplasmacytic infiltration in the lamina propria and crypt distortion. Fibrosis/collagen deposition was found in 38.8% of IBD population compared to 12.2% of non-IBD population (p=0.003). Most IBD cases (55.1%) were categorized as active phase IBD.Conclusion: Since the most common histologic findings in IBD patients were also found in non-IBD patients, IBD diagnosis based on histopathology alone is highly inadvisable. However, there were also lack of clinical data and endoscopy findings in most of colorectal biopsies sent for IBD evaluation. Along with overlapping and unspecific morphology and suboptimal events during histological evaluation, all of this complicated the diagnosis of IBD. Hence multidisciplinary approach is required for a better IBD diagnosis and treatment.

Published: September 2021

Background: This study aimed to evaluate the endoscopic features and clinical outcome of patients with chronic radiation proctitis (CRP) at one year after argon plasma coagulation (APC) treatment. Method: Between March 2016 and September 2019, a total of 48 female patients with CRP were treated with APC and their medical records were retrospectively reviewed. APC treatment was done every 3 to 54 weeks, with a median of 8 weeks. Number of APC was decided by the treating physician according to the severity of illness. Endoscopic and clinical features at one year after the final APC were recorded as the effectiveness of APC.Results: Of 48 patients, 26 patients were included in this study. Number of APC sessions varied between 1 to 5 sessions of APC for each patient. Of 26 patients, 22 patients achieved clinical improvement and four patients did not achieve clinical improvement at one year after the last APC session. Of the four patients who failed to achieve clinical improvement, two patients underwent surgery, one patient had occasional mild rectal bleeding, and one patient required regular transfusion. Of 22 patients with clinical improvement at one-year after the last APC, improvement of endoscopic features was found in 20 patients. Of four patients who did not achieve endoscopic improvement, diagnostic colonoscopy showed telangiectasis of more than 50% of rectal surface in 1 patient, presence of blood in 2 patients, and presence of ulceration of 1 cm in 1 patient.Conclusion: APC is an effective treatment option for CRP.

The aimof the study was to assess the clinical and genetic factors associated with the risk of recurrent ischemic events in patients with stable stenocardia (SS).Materials and methods.A total of 100 patients with SS were examined and followed-up for 15.3±8.3 months. The patients were divided into subgroups (SG): SG1 (n=51) – persons without events, SG2 (n=49) persons with recurrent ischemic events (hospitalization due to the development of pain syndrome, re-stenting due to stent restenosis, myocardial infarction, cerebral infarction and death from cardiovascular causes), SGB (n=11) – persons with «major» recurrent ischemic events (re-stenting due to stent restenosis, myocardial infarction, cerebral infarction and death from cardiovascular causes) , SGG (n=89) – persons without «major» events. The obtained survey data (general clinical, aggregometry, polymor  phism of genes of platelet fibrinogen receptor ITGB3 (T1565C), platelet collagen receptor ITGA2 (C807T), ADP platelet receptor P2RY12, H1/H2 (T744C)) were analyzed using the STATISTICA 10.0 software.Results.In SG2, men predominated (χ2=9.2; p<0.01), past MI was more common (χ2=4.8; p<0.05), more stents were implanted (2.4±1.9 versus 1.7±1.1, p<0.05), TRAP-test values were higher (p<0.05) compared to SG1. In SGB, greater number of stents were implanted (3.1±2.2 versus 1.61±1.57, p<0.05), the carriage of the TC genotype of the ITGB3 gene was more common, (p<0.05), a combination of gene mutations ITGB3 and P2RY12 was more common, (p<0.05) compared to SGG. A logistic regression equation was constructed, including the presence of diabetes mellitus, the number of platelets in the blood test, the ASPI-test values, the carriage of the 1565C allele of the ITGB3 gene, the number of stents implanted, which makes it possible to determine the likelihood of developing «major» recurrent ischemic events with a cut-off threshold LP₀=0.0965, with sensitivity – 81.82 %, specificity – 78.48 %, overall accuracy – 78.89 %.Conclusions.The factors associated with the development of recurrent ischemic events are: male sex, previous MI, a greater number of implanted stents, and high TRAP-test values. The factors associated with the development of recurrent «major» ischemic events are: a greater number of implanted stents, carriage of the TC genotype of the ITGB3 gene, carriage of a combination of mutations of the H1/H2 polymorphic locus of the P2RY12 gene and the T1565C polymorphic locus of the ITGB3 gene, diabetes mellitus, the number of platelets in blood test, ASPI-test values.

Despite the fact that the phenomenon of unrecovered coronary blood flow (no-reflow) has long been known, there is still no unanimous opinion about the predictors and, accordingly, the risk groups for its occurrence. This prevents predicting the further course of the disease and investigating the effectiveness of therapeutic and surgical methods for preventing the consequences of reperfusion in patients with ST-segment elevation myocardial infarction, which in turn worsens the postoperative and long-term prognosis in this group of patients. We used the search engines E-library, Google Scholar and Pubmed to search for studies on this issue. The article presents and analyzes research data covering the predictors of the no-reflow phenomenon. The difficulties in identifying them are also described, the issue of a diagnostic approach ans sampling for research is raised. A review of studies dedicated to the identification of predictors of the no-reflow phenomenon using optical coherence tomography and intravascular ultrasound is given.

Published: September 2021

Introduction.The state of the blood flow within the capillaries and close blood vessels is highly important in practice for the revealing of pathogenetic mechanisms of both systemic and local circulatory disorders.Aimof the study was to define the parameters of microcirculation and the level of blood flow fluctuations (flux) in the distal segments of upper and lower limbs (in fingers of hands and toes of feet) in children of 6–7 years old; and to describe the possible differences in the mechanisms of blood flow modulation in boys and girls.Materials and methods.Skin microcirculation was assessed in middle fingers of hands and great toes of feet in children of 6-7 years old (14 girls and 7 boys in prone position) by means of laser doppler flowmetry.Results.The ranges for parameters of microcirculation (PM) for distal segments of upper and lower limbs in children of mentioned age group were defined, also it was shown that the PM are significantly lower in the lower limbs comparing to those of the upper limbs (both in groups of girls and boys). Asymmetry of PM in the feet was not found; the features of right hand-left hand asymmetry for PM in girls and boys are described. The analysis of modulation of blood flow fluctuations (fluxmotions) of different frequencies showed the profound role of vasomotor (myogenic) rhythm for regulation of microcirculation.Conclusion.Increased neurogenic influences on the modulation of fluxmotions in girls of 6-7 years old may be an evidence of the ongoing development of the mechanisms of blood flow regulation, particularly the association with the growth rate of girls is possible.
Fleeing War, Fighting Xenophobia
Authors: Danziger Andrea
Published: September 2021

The purpose of this research is to identify the key differences between German and American refugee policies as they relate to the ability of each country’s native population to successfully integrate refugees into their society. This body of work looks specifically at the German and American Refugee Resettlement Programs submitted to the United Nations. As shown in this research, new legal policy that can fight systematic distrust and discrimination becomes achievable by identifying the practices that contribute to in- and out-group dynamics between host country and refugees. Such policies will allow for the building of stronger, more integrated societies in the future. While Germany and the United States display both strengths and weakness in varying aspects of their respective refugee policies, neither has a significantly superior Refugee Resettlement Program.
Mad Insight
Authors: Dumaresque Renee
Published: September 2021

This poem is informed by the relationships between gender, race, chronic pain, hysteria, and the role of dominant discourses in shaping interpretations of bodily and psychic pain. Drawing on my lived experience as a non-binary person with chronic vulvar pain, or vulvodynia, I challenge the psychiatrization of chronic pain and propose hysteria as a potential state of resistance and refusal (Dumaresque, 2019). I weave fog throughout this poem as a metaphor that captures pain, madness, and perception. Fog symbolizes disruption and disorientation; yet, fog also gestures to the potentiality of being displaced from normative insight (Bruce, 2017).  I engage William Connolly’s (2010) reading of perception as formed through discipline to think through the silent but subversive waves of knowledge and power that carve the lenses through which we story ourselves and others (Erickson, 2016).  As Thomas King (2003) writes, “the truth about stories is that’s all we are” (p. 32). This poem is situated in a reading of madness and hysteria as sites of affective protest (Dumaresque, 2019). I ask, what can be resourced from our becoming un-hinged? This poem contributes to mad knowledge that is intersectional and in-service to disrupting medical and psychiatric violence, whiteness, hetero/cis-governance, and “compulsory able-bodymindedness” (Sheppard, 2018, p. 59).
Quarantine Diaries
Authors: Park Gloria
Published: September 2021

The following six diary entries and journaling pieces were written in the months after the 2019 Coronavirus pandemic (COVID-19) hit Canada. They express my attempts to pinpoint causes of my personal unhappiness and how overwhelming expectations of productivity affected my mental health and relationships during quarantine. My diary entries are in chronological order, containing reflections on my birthday in quarantine, notes about racial injustice, and reminders of self love. I delve into how isolation and social distancing shifted my perspective, creating unexpected goals, and new hobbies. These reflections reveal thoughts of uncertainty about my career and concerns about my friendships. As the entries continue, themes of self-acceptance and confidence emerge. I encourage readers to empathize with these conflicting feelings of what is “normal” or “expected” during adulthood; challenge destructive behaviour, including excessive self doubt and self-sabotage; and form uplifting habits for a better sense of self. My words have been taken directly from my personal journal and left as they are, no editing, no revising, no polishing. This composition creates an open space that acknowledges how emotions of guilt, anxiety, low self-image, sadness, and hope defined so much of our post-COVID-19 reality.

Esta investigación trata de determinar en qué medida hay manifestaciones de síntomas de ansiedad ante los exámenes y contrastar los resultados con el rendimiento académico, el tiempo de estudio, la titulación y el sexo.Método. La muestra estaba compuesta por 1021 estudiantes realizándose un muestreo aleatorio estratificado. Se utilizó un Inventario ad hoc de Estrés Académico. Se han realizado análisis de medias, sus contrastes a través del ANOVA, prueba t, análisis de tablas de contingencia con Chi cuadrado e inferencias con la correlación bivariada de Pearson.Resultados. Existe una población de estudiantes universitarios muy amplia con una ansiedad preocupante o muy preocupante frente a los exámenes en respuestas cognitivas, fisiológicas y motóricas. Sin embargo, los datos no son concluyentes en la incidencia sobre el rendimiento académico.Discusión y Conclusión: La ansiedad juega un papel determinante en la realización de un examen. Por ello, se ha de reflexionar sobre el sufrimiento que, tal y como se muestra en este estudio, padecen los discentes hasta haber realizado el examen.

Embora práticas de ciência aberta tenham sido adotadas em diversos campos do conhecimento ao longo dos anos, em larga medida estão concentradas nem campos como as ciências naturais, exatas e computação. Nas Ciências Humanas a migração para a ciência aberta ainda é incipiente. Neste trabalho, apresentamos Portal multimodal/multilíngue para o Avanço da Ciência Aberta nas Humanidades, apoiado pelo CNPq por meio do Edital 25/2020, destinado a ajudar a preencher essa lacuna. O Portal prevê fornecer uma série de conteúdos relacionados à ciência aberta nas Humanidades, incluindo dados verbais, visuais, verbo-visuais e verbo-gestuais, por meio dos quais possam ser desenvolvidas pesquisas, nacionais e internacionais. O Portal foi concebido em torno de quatro vetores, a saber: acesso aberto, dados abertos, fonte aberta e ciência cidadã / humanidades cidadãs. O trabalho apresenta, em relação a cada um dos vetores, a problemática envolvida bem como as ações pretendidas. Além disso, são apresentados os princípios de design do Portal, visando à sua usabilidade e acesso. O movimento de abertura da ciência exige novas posturas e novas práticas, que o Portal pretende estimular, pois entende que esse movimento é em última análise responsável pela democratização da ciência.

Esta pesquisa teve como objetivo verificar a existência de variantes de vozeamento das vogais altas pretônicas no Português Brasileiro. Para tal realizando a gravação de áudio de 06 (seis) informantes de São Paulo, sendo 03 (três) mulheres e 03 (três) homens, de 20 a 35 anos e com o ensino superior. O corpus para a análise acústica foi formado pela gravação, em cinco repetições aleatorizadas, de vocábulos quadrissílabos e pentassílabos na frase veículo “Diga ____ logo”, totalizando de 1.440 frases, contendo os vocábulos alvo. Nossos resultados confirmaram que, em contexto pretônico medial, os falantes realizam três variantes das vogais altas, a saber: vogais vozeadas, parcialmente vozeadas e desvozeadas, sendo as vozeadas de maior ocorrência, 55,62%. Foi possível observar também que houve diferença na realização das variantes entre: a vogal alta anterior e posterior; sujeitos do sexo feminino e masculino; quadrissílabos e pentassílabos; e entre consoantes da sílaba alvo, porém, em sua maioria, prevalecendo a variante vozeada.
Using a coupled-oscillator model of speech rhythm to estimate rhythmic variability in two Brazilian Portuguese varieties (CE and SP)
Authors: Arantes Pablo , Lima Júnior Ronaldo Mangueira
Published: September 2021

This paper presents preliminary results of a semi-automatic methodology to extract three parameters of a dynamic model of speech rhythm. The model attempts to analyze the production of rhythm as a system of coupled oscillators which represent syllabicity and phrase stress as levels of temporal organization. The estimated parameters are the syllabic oscillator entrainment rate (alpha), the syllabic oscillator decay rate (beta), and the coupling strength between the oscillators (w0). The methodology involves finding the  combination that minimizes the distance between natural duration contours and simulated contours generated using several combinations of the parameters. The distance between natural and model-generated contours was measured in two ways by comparing: (1) plain or overt syllable to syllable duration and (2) relative change along both contours.We applied this methodology to read speech produced by five speakers of the state of Ceará (CE) and eight speakers of the state of São Paulo (SP). Mean w0 and alpha values are compatible with the view that Brazilian Portuguese is a mixed-rhythm language. Results from two bayesian hierarchical regression models do not suggest a difference between SP and CE speakers, but indicate a difference between the two methods, with the relative change method generating lower alpha values and higher w0 values, and the reverse for the plain duration method.

This study presents as a problem-question whether the use of the audiobook will provide the visually impaired person with the condition to adhere, take ownership, make individual and collective use ofnew technologies, these human creations whichrepresent the possibility of an increasingly growing mastery of information never imagined and its new ways of use.Within this context, the research has the following objectives: to analyze the importance of the audiobook as a pedagogical tool, as mediator of reading classes for students with visual impairment; to analyze whether digital technologies can be used to support the teaching and learning process.Regarding tothe approach ofthe problem, the research has a qualitative focus. For data collection, interviews and online questionnaires sent by WhatsApp were used. The research population and sample comprised 13 (thirteen) subjects. To carry out the interviews, several technological resources were used: Google Meet; WhatsApp and cell phone (phone call).Due to the pandemic –Covid 19 and the inevitable social isolation, digital technology was the best option for conducting the research. The interviews were transcribed using theTranscriber for Whatsappand Call Recorderapplications. The study reveals that digital technologies can and should be used to support the process of teaching and learning to students with visual impairments.That the audiobook represents another reading alternative, a complement, a support, with its own attractions, benefiting people with or without disabilities.As from the social representations extracted from the research subjects’speeches, it was possible to see that assistive technologies need to gotogether with the Braille system, called as a literacy technology, a method whichallows the visually impaired to read and write without intermediation, in other words, the person has direct contact with the text.

The population's consumption behavior in general has been changing over the years, as a result of several factors, such as increased market competitiveness, high supply of products and services, technological advances and macro-environmental factors. Considering that the factors caused by the macro environment are uncontrollable variables and exert force on the entire micro environment such as companies, consumers, suppliers and competitors. This reality requires companies to be constantly aware of all changes in the market to adapt and promote new strategies in order to meet consumer demands. The pandemic, caused by COVID-19, has directly impacted the entire micro environment, from the way companies can operate to the way the market will consume, whether this change is caused by a government decree or by a new need for behavior of the consumer. With the population inserted in what is called the “new normal”, it becomes evident that consumption habits have undergone great changes. Given the current scenario and the restrictions on the functioning of activities caused by the COVID-19 pandemic, it is considered that such a change in the economic pattern and in the offer of products/services directly affects the way society is consumed, generating new needs and desire to consumption. Therefore, the question is how to identify the new post-pandemic retail consumption pattern? From this questioning, this research aimed to develop an investigation model on the new pattern of retail consumption in the city of Campos dos Goytacazes after the changes caused by the COVID-19 pandemic. For the methodological construction of the research model of the new pattern of consumption caused by the pandemic, a bibliographic survey was carried out based on five articlesfrom 2014 to 2020, classified into 4 dimensions: Market and Economy; Social and Cultural Aspects; Life Stage; and Needs and Desires. From the definitions of dimensions, criteria for investigating the new consumption pattern were developed. In addition, tocompose the model and identify the consumer and their perception of the changes in their behavior caused by the pandemic, two more dimensions were established. The first is called the Consumer Profile, which asks questions about age, gender, income, occupation, education, etc. and the second, Changes caused by COVID-19, in which the consumer is asked about the purchase frequency, purchase volume, purchase channel, etc. However, the application of this model seeks to identify the new consumption pattern of consumers in the city of Campos dos Goytacazes from the changes caused by COVID-19

The Urban Policy of Brazil, established with the Federal Constitution and the City Statute, brought to light a series of instruments to be used by municipalities in their urban planning. The objective of this research was to verify the use of these instruments in the laws of the cityplans of 2008 and 2020 in the city of Campos dos Goytacazes, state of Rio de Janeiro. In the methodological aspect, online meetings through Google Meet were fundamental for bibliographical and documental survey, comparative analysis of the laws of cityplans, elaboration of a table with results and elaboration of an article. With the study it was possible to analyze the use of urban policy instruments in the analyzed cityplans. It was found that in the two cityplans, several instruments are included in the law in a bureaucratic way, without elements that indicate possibilities of application. It was concluded that the use of urban policy instruments in the analyzed cityplans happened in a similar way. The difficulty of applying many instruments was evident in both studied plans
