Architectural Interventions to Mitigate Occupational Stress Among Office Workers
Authors: Norouzianpour Hirbod
Published: January 2021

Stress is one issue that affects the health and well-being of every building occupant. The negative effects of stress are more pronounced in workplaces, where stress can act as a major agent of disease and an impediment to employee productivity and satisfaction. The underlying causes of occupational stress are varied and include job insecurity, extended hours, excessive workload, altercations within the organization, tight deadlines, changes in responsibilities, and lack of autonomy, among others. One of the factors that can contribute to overall occupational stress is the working environment itself—a factor that can be mitigated by design. While occupational stress may arise from a multiplicity of causes, designers have numerous interventions they can employ to decrease it.

The literature on occupational health, well-being, satisfaction, and productivity is broad and multifaceted; however, this paper is limited to exploring stress factors that correlate with the built environment and focuses on employees who are experiencing a high rate of stress in office buildings as the target group. To address these issues, supporting literature was explored to identify environmental interventions that could reduce stress or enhance the stress-coping abilities of workers in offices by improving the environmental quality of the built environment.

This article explores the following questions: How does space cause people to experience mental stress? In what ways can the built environment itself be a generator of stress? What are the main environmental factors in offices that can mitigate the stress levels of employees or help them to recover more easily from work-related stress? To answer these questions, it is necessary to understand the causes and mechanisms of chronic stress, including work-related stressors, and to identify the factors in the built environment that can be associated with occupational stress. The present paper is based on concurrent analyses of supporting literature in the rather different fields of architecture, public health, psychology, management, and environmental studies. The outcome is an identified set of practical strategies that provide solutions for healthier and more productive workplaces. By concentrating on measures that can reduce employee stress levels, these strategies can be used as a source for evidence-based workplace designs.
Rituales de libertad: disciplina y biopolítica de la arquitectura docente
Authors: León Casero Jorge , Castejón Esteban José María
Published: December 2020

Según Michel Foucault y Peter Sloterdijk la arquitectura es un conjunto de técnicas y dispositivos materiales cuyo objetivo es producir sujetos domesticados según un tipo específico de poder. La arquitectura propia del poder disciplinar pretende producir individuos homogéneos acordes con una norma ideal definida a priori a través de unos rituales espaciales lineales y unívocos. En cambio, la arquitectura propia del poder biopolítico utiliza la interconexión de espacios y la indeterminación programática con el objetivo de hacer funcionar la libertad de las personas como medio de auto-domesticación productiva. Dado que la arquitectura docente es una de las principales categorías arquitectónicas involucradas en la producción de sujetos, analizamos tres proyectos paradigmáticos –el colegio Sant’Elia de Giuseppe Terragni, la escuela en Broni de Aldo Rossi y el McCormick Tribune Campus Center de OMA- que muestran el modo en que la arquitectura ritualiza la conducta de sus usuarios.
Ritos e hitos de una comunidad hídrica en el Valle del Rosal
Authors: Santos Vázquez Ángeles , Seoane Prado Henrique , Martínez-González Carlos
Published: December 2020

En determinados ambientes inciertos y complejos, una comunidad es capaz de dejar atrás dinámicas competitivas y cooperar para compartir y gestionar recursos escasos y renovables de forma común. Son precisamente estas comunidades, capaces de unir recursos y hacer de ellos buen uso, las que tienen más esperanza de éxito a largo plazo para habitar espacios que, de otra manera, resultarían difícilmente habitables.Mostrando un estudio de caso de un pequeño valle de Galicia, seguramente extrapolable a muchos otros, se hace evidente la importancia de los rituales que se suceden en cuanto al uso del agua, como mediadores entre la competitividad y la cooperación.La compleja gestión comunitaria de este recurso escaso, para su reparto proporcional y equitativo, sin apenas perturbar el ciclo natural del agua, requiere de pequeños rituales, que se suceden a lo largo de toda la estación seca, que permiten y refuerzan, y esto es muy importante, la cooperación.

Published: January 2021

A pesar de los beneficios de la actividad física sobre la salud, la mayoría de los adolescentes no alcanza un nivel suficiente. El objetivo de esta investigación fue analizar las propiedades psicométricas propuestas por Moreno, Moreno y Cervelló para el cuestionario Medida de la Intencionalidad para ser Físicamente Activo. La muestra total fue de 496 adolescentes mexicanos 232 deportistas y 264 no deportistas, con edades comprendidas entre 12-15 años (M = 12.95; DE = 0.47). La estructura factorial del cuestionario se analizó mediante análisis factoriales confirmatorios. Los análisis, muestran que una estructura unifactorial es viable y adecuada tanto para la muestra total (GFI .999; RMSEA <.001; CFI 1.000) como para las poblaciones de deportistas (GFI .995) y no deportistas (GFI 1.000). La estructura unifactorial, atendiendo a criterios estadísticos y sustantivos, ha mostrado adecuados indicadores de ajuste de fiabilidad y validez. Por otro lado, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes de acuerdo a la variable práctica deportiva; sin embargo, existen diferencias entre deportistas y no deportistas para la media de intencionalidad para ser físicamente activo. En conclusión, el cuestionario Medida de la Intencionalidad para ser Físicamente Activo puede ser considerado una herramienta útil para avanzar en el estudio de los factores que afectan a la práctica de actividad física.

Published: January 2021

El presente estudio tiene por objetivo analizar los motivos y las barreras para la práctica de actividad física (AF) en personas con discapacidad visual practicantes de goalball. En este estudio participaron 25 personas adultas (32,7 ± 11,9 años), de las cuales 14 eran mujeres (31,3 ± 12,0 años) y 11 eran hombres (34,4 ± 12,2 años) teniendo todos licencia federativa en vigor expedida por la Federación Española de Deportes para Ciegos. Los participantes completaron el cuestionario Motivos y Barreras para la Actividad Física y el Deporte (MBAFD). Los mayores motivos para practicar AF fueron los relacionados con el gusto por la actividad y por las sensaciones positivas que les transmitía. La mayoría de los ítems sobre los motivos para la actividad física y el deporte (AFD), obtuvieron una puntuación alta. La falta de actividades físicas adaptadas y la falta de espacios próximos donde practicar AF, fueron las barreras más destacadas para la AFD. Cabe resaltar que los participantes no percibían excesivas barreras en los ítems para la práctica de la actividad deportiva (< 1,2 ± 1,3). Salvo en ítems muy puntuales, no se obtuvieron diferencias significativas en función del sexo, el origen de la discapacidad y los años de experiencia en la práctica de otras modalidades deportivas previas a la práctica del goalball. Todo ello, puede deberse al hecho de que los participantes fueran personas con discapacidad visual asiduos practicantes de goalball, condicionando de este modo los resultados obtenidos.
So called athletic identity, incompatible with reality: Static identity structure, status transitions and health behaviour dynamics in student athletes
Authors: Boz Berkcan , Kiremitci Olcay
Published: January 2021

The aim of the present study is to examine the athletic identity, status transitions and health-related behavioral dynamics of student athletes. Descriptive survey model was used and 398 individuals participated in the present study. Data was collected by Athletic Identity Measurement Scale (AIMS), information form, ranking and closed-ended qualitative questions. According to findings, it was found that the students' downright transitions increased in processes. On the contrary, ANOVA analyses show no differences in athletic identity scores according to grade levels (p>.05). An increase was seen in maladaptive health behaviors (p<.05). Additionally, maladaptive health behaviors increase after sport termination and beginning of university. It was concluded as a result of the study that individuals' acceptance of athletic identity becomes continuous in spite of the changes in their sport participation status; however, health behaviors are not compatible with the continuity of athletic identity.
Elementary Freshmen’s Mathematical Attitudes in Teaching Incorporating Free Problem Posing Activities
Authors: ARIKAN Elif Esra , DEDE Yüksel
Published: December 2020

This study aims to investigate the impact that teaching incorporating free problem-posing activities has on primary school preservice teachers’ attitudes toward mathematics. As such, this study employs an embedded mixed methods design that integrates a semi-experimental design. The participants of this research consisted of 33 freshman primary school preservice teachers attending at a university in the Marmara region of Turkey during the fall semester of the 2017-2018 school year. The participants were selected using convenience sampling. The study’s data were collected using two instruments: the mathematical problem-posing test and the mathematics attitudes scale. The quantitative data of the study were analyzed using descriptive and inferential statistics whereas qualitative data were analyzed using content analysis. The quantitative findings revealed there to be a statistically significant difference between the pretest and the posttest scores for the entire mathematics attitudes scale and for the interest-love sub factor. The qualitative findings, however, indicated that preservice teachers’ opinions could be grouped into two main categories: the affective dimension and the cognitive dimension.

Authors: Bressan Flávio , Toledo Geraldo Luciano
Published: December 2020

O trabalho investigou a influência da data de validade nas atitudes, decisões de compra, e consumo de alimentos. Realizaram-se 12 entrevistas e um levantamento (n=199), cujos dados foram submetidos à análise fatorial, Teste t e análise de variância (ANOVA). Os resultados indicaram relação entre o conhecimento sobre conservação e consumo, validade e consumo de alimentos, mas não sobre o consumo de alimentos vencidos e nem relação entre riscos, compra e consumo destes alimentos vencidos. Indicaram, também, que os entrevistados parecem basear suas decisões mais na aparência do alimento e na experiência pessoal do que nos riscos percebidos sobre validade vencida, o que é um indicativo da necessidade de ações educacionais para torná-la fator de influência nas decisões de compra e consumo de alimentos.

Rings Whose Units Commute with Zero Divisor Elements
Authors: YILDIRIM Tülay
Published: December 2020

This paper is about rings R for which units commute with zero divisors. These rings are called uni-zero divisor rings. It is deduced that uni-zero divisor ring is not abelian and also give several examples of some important classes of rings (a kind of integral matrices, matrix ring over any stably finite ring ) that are not uni-zero divisor ring. Here many characterizations of uni-zero divisor rings are compared with well-known classes of rings. Moreover, the uni-zero divisor rings property is studied under some algebraic constructions.

Description Of Natural Events with Correct Reference Body
Authors: AYGÜN Ulukan , ORTAÇ KABAOĞLU Rana
Published: December 2020

The beginning of life could not be described on Earth, yet. For this reason, natural phenomena have been described with the starting point uncertainty. Natural events could not be described by a single field. In H. Brown’s study [1], the main lesson that emerges is described as the special theory of relativity is incomplete. For that reason, the aim of this study is to describe physical reality in a single field. In the light of this aim, first of all, coordinate systems which are under-established are defined. The reason for the deficiency is explained. The system of unified coordinates, which is based on the correct basis, is explained. Moreover, in this study, the coordinate systems which are defective with respect to each other are described. In addition, in this study, the theory describing the relation of these coordinates with the reference body with a single field is explained and proved by equations. Furthermore, the beginning of life is explained by Lorentz Transformation Equations and Gauss Coordinate Systems. At the end of the description, new interpretations, interpretations supporting previous interpretations of scientists, or equations stating that they are wrong are explained. As a result, in this study, the equivalent of the reference body in the natural system is explained

Published: December 2020

Chalcones are known as versatile, innovative and bioactive chemical scaffolds in drug development studies. In this study, a series of poly-methoxylated chalcones (1-8) were synthesized by Claisen-Schmidt condensation under the basic condition and their carbonic anhydrase (CA) I/II and acetylcholinesterase (AChE) inhibitory effects were firstly evaluated in this study. CA isoenzymes I and II were inhibited in nanomolar concentration with Ki values of 8.75±0.64 - 37.64±2.38 nM (hCA I) and 11.47±3.31- 45.97±4.67 nM (hCA II). The compounds inhibited the AChE enzyme in the range of 34.14±20.79 - 53.65±13.25 nM. The compounds 1, 3 and 5 were the best inhibitors against hCA I, hCA II, and AChE, respectively. The bioassay results showed that the compounds can be considered as the main frame to design novel chalcone-based enzyme inhibitors.

In this study, the effects of different doses (0, 25, 50, 75, 100, 125, 150 and 175 ppm) of Tebuconazole substance on the quality and development of melon seedlings (seedling and stem length, stem diameter, number of leaves per plant, leaf, stem, and root dry matter contents and chlorophyll content) were investigated. According to statistical evaluations, it was determined that different dose applications cause a significant change in seedling characteristics. According to the data obtained, a reduction of 57.5% and 55.9% was achieved in seedling length and stem length, respectively, compared to the control application. And the stem diameter increased by 9.95% after the application. The dose application also provided an increase in leaf chlorophyll content. In this study, applications of Tebuconazole at different doses were found to control the seedling height in melon and positively affect specific quality characteristics of seedlings.
Long term Fluoride Release of Newly Developed Alkasite Based Restorative Material
Authors: EGİL Edibe
Published: December 2020

Abstract: Glass ionomer cement in dentistry prevents demineralization process through its fluoride release property and is effective in the induction of remineralization phase. Being low of flexural strength of glass ionomer has caused the search for different materials that can release fluoride. In this study, fluoride release of new alkasite based filling material which has been developed as an alternative to glass ionomer cement has been evaluated. Three commercially available filling materials were tested for the present study: Traditional glass ionomer (Ketac Molar Easymix, 3M ESPE, Germany), resin modified glass ionomer (Nova Glass LC, Imicryl, Konya,Turkey) and Alkasite filling (Cention N, Ivoclar, Vivadent,Schaan, Liechtenstein). Fluoride release of three filling materials were measured at certain intervals for 63 days. Nova Glass LC, Ketac Molar easymix and Cention N released fluoride throughout the study. Fluoride releases of Nova Glass LC for the first 24 hours were significantly higher than Ketac Molar and Cention N group (p<0.05). It has been observed that Cention N can release fluoride in the long term just like Ketac Molar Easymix and Nova Glass LC glass ionomer cement.

Published: December 2020

In this study, the antioxidant properties, chemical compound profiles and some physical properties of fruit, pulp, pure pestil and hazelnut added pestil of plum (Prunus salicina) were determined. The chemical compound profiles of the samples were detected using GC-MS (gas chromatography–mass spectrometry). The antioxidant properties were determined by the total phenolic content and DPPH and ABTS radical scavenging activity analysis. According to the results obtained, the total phenolic content of the samples varied between 130.915 mg GAE / g - 146.565 mg GAE/ g. In addition, it was determined that the concentration increase occurring in pulp and pestil production steps significantly increased the DPPH and ABTS radical scavenging activities of the samples (p <0.05). Results of the GC-MS showed that the plum pulp, pure pestil and hazelnut added pestil contained 35, 32 and 28 chemical compounds, respectively. Furans, ketones, carbohydrates and aldehydes were the most abundant compounds found in both the pulp and pestil samples. 5-hydoxymethylfurfural was the main chemical compound in all of the samples (38.52-61.61%). In addition, the dry matter value was found to be between 19.335-89.067%, ash value was between 2.075-4.145%, pH value was between 3.680-3.835, protein value was between %0.315-4.385, L* values were between 21.775-29.385, a* values were between 3.120-13.090 and b* values were between 1.450-6.925, respectively.

Background: Umbilical cord is one of the fetal membranes. It is developed from the yolk sac. Umbilical cord is tubular structure. Approximate length of the cord is 50 cm. Umbilical cord around the neck is called as the nuchal cord. The aim of the study is to find out the incidence of umbilical cord around the neck at the time of delivery and its fetal outcomes.Methods: It is a retrospective observational study. This study was conducted in the department of obstetrics and gynecology at a tertiary care hospital over a period of 6 months (Feb-Jul 2020). Out of 542 patients, 388 were enrolled in this study after the inclusion and exclusion criteria, of which 101 were delivered with umbilical cord and the remaining were 287 patients in control group.Results: Present study showed 38.4% incidence of umbilical cord at the time of delivery. Incidence is more among the primigravida and it is statistically significant. Both intrapartum and postpartum risks are not related to umbilical cord around the neck. Mean length of the cord in patients delivered with cord around the neck is more when compared to the control group and has significant p value.Conclusions: This study concludes that the presence of umbilical cord, alone is not an indication for caesarean section. Umbilical cord with 3 loops was associated with increased operative delivery and low Apgar score, proper intrapartum surveillance and portogram leads to good fetal outcome.

Post-inflammatory hyperpigmentation (PIH) is a multifactorial disorder linked to alterations in melanin pigment because of inflammatory skin condition or any injury. Acne-induced PIH is one of the common presentations observed in dermatological consultations in India, especially in females of younger age group. A wide range of topical depigmenting agents are available for effective clearance of hyperpigmentation in patients affected with acne. Besides, chemical peels and cosmetic procedures like lasers and light therapies are commonly employed. However, treatment of acne-induced PIH is challenging in Indian clinical settings for multiple reasons such as relapsing of the condition and long-standing nature of the disease; the tendency of treatment to cause pigmentation; insufficient clinical data on natural ingredients; and lack of clinical practice guidelines, exclusively for the management of PIH in Indian patients. An experts’ panel discussion involving dermatologists all over India was conducted to review the evidence-based concept of acne-induced hyperpigmentation, and to obtain expert opinions on effective and practical management of acne-induced PIH in Indian settings. This article outlines consensus expert opinions aimed at identifying, diagnosing, and managing acne-induced PIH using topical depigmenting agents in Indian patients. It also highlights effective preventive strategies, the role of patient counselling and education regarding awareness about the disease and its treatment strategies.  
Memes and Social Messages: Teaching a Critical Literacies Curriculum on DAPL
Authors: Beucher Becky , Low David , Smith Amy
Published: January 2021

This article documents the design and implementation of a culturally responsive critical media literacies curriculum centered around media representations of the Dakota Access Pipeline (DAPL). Students (grades 6-8) were invited to discuss media imagery relating to DAPL and to create memes reflecting their understandings. To situate this work, we articulate a framework that blends critical media literacies and culturally responsive and sustaining pedagogy. We analyze students’ spoken and multimodal responses to a curriculum that purposefully foregrounded Native perspectives and digital media. Ultimately, we argue that students must be invited to leverage their epistemic privilege in responding to contemporary social issues.

This qualitative study explores Asian American high school students’ perceptions of social studies. The study finds that students affirm the value and significance of learning social studies. Their different interpretations of social studies further reveal that their social studies learning experiences have been influenced by their teachers’ beliefs and practices on social studies curriculum and instruction, and the interplay with students’ complex and multi-faceted identities. The findings of this study suggest a comprehensive and diversified curriculum and culturally relevant teaching in social studies.
Quando as personagens se sentam à mesa: a narrativa de Senna Fernandes de Luís Cardoso
Authors: D'Alte Pedro
Published: December 2020

Senna Fernandes e Luís Cardoso são importantes escritores no panorama literário português e fornecem, sobre o Oriente, quadros literários que permitem, ao leitor, ampliar a experiência lusófona em vários prismas: social, étnico, histórico, cultural e literário. O presente exercício concretiza uma abordagem literária que torna mais visível a relação entre Macau e Timor. Sincronicamente, centrando-se nos momentos passados à mesa, a análise torna explícita choques identitários, conflitos étnicos e religiosos e determinados momentos históricos ocorridos entre as personagens, na primeira metade do séc. XX.
O inespecífico e a forma
Authors: Azevedo Luciene
Published: December 2020

A noção de forma é cultivada como indispensável à arte desde Kant. E mesmo que os formalistas tenham tentado dissolver a oposição entre forma e conteúdo, esse embate continua mais vivo que nunca no presente. Ao analisar o trabalho de Nuno Ramos, Florencia Garramuño afirma que as obras do artista “se distancia[m] de questões puramente formais” e que o espectador é levado a “considerar os efeitos e enigmas” que a obra produz “em vez de concentrar-se na forma estética”. Também no Indicionário do Contemporâneo, no verbete sobre as “práticas inespecíficas” do presente, lemos que obras que se expandem na direção de outros gêneros ou materiais (artísticos ou não) “colocam em xeque uma noção de forma definida”. Considerando a relação entre as noções de inespecificidade e forma, nesta comunicação, gostaria de investigar melhor o conceito de forma e sua operacionalidade para as obras inespecíficas produzidas hoje. A premissa principal é que embora muitas produções não possam ser identificadas a gêneros específicos, talvez seja possível considerar que a inespecificidade é um indício que sugere a reinvenção das formas de contar no presente, mas não seu descarte. Assim, a comunicação quer realizar um levantamento teórico sobre a noção de forma para refletir sobre sua validade hoje, tomando para análise o mais novo romance da escritora mexicana Valeria Luiselli, Arquivo das crianças perdidas.
O sertão como Paisagem: a relação subjetiva do espaço em Galileia, de Ronaldo Correia de Brito
Authors: Negrão Berlini de Andrade Ana Carolina
Published: December 2020

Este artigo pretende analisar as relações entre subjetividade e espaço no romance Galileia (2009), de Ronaldo Correia de Brito. Nessa obra, percebemos que a descrição do sertão, espaço onde transcorre a narrativa, é mediada pela psicologia do narrador-protagonista, cujos estados emocionais direcionam a apreensão e a criação de uma Paisagem literária, segundo terminologia de Michael Jakob. Assim, o nosso objetivo é demonstrar como são construídas as imagens espaciais, utilizando, para tanto, as concepções de Jakob, para quem a Paisagem literária é marcada pelas relações de subjetividade e de distanciamento do sujeito em relação à natureza. A fim de explicitar a construção da espacialidade em Galileia, também utilizaremos o conceito de cronotopo, de Bahktin (1988), e de memória-acontecimento, de Mariana Luz Pessoa de Barros (2011).
Rui Torres, precursor de Herberto Helder e Raul Brandão: reimaginação na poética digital
Authors: Petrin Grande Keilla Conceição , Da Silva Rogério Barbosa
Published: December 2020

A literatura digital é uma das vertentes da literatura contemporânea, cujos textos partem de recursos hipermidiáticos e digitais em seu processo de elaboração. As escritas assim caracterizadas tanto apresentam inovações no campo estético, quanto preservam, reconfiguram e renovam modalidades do fazer literário inscritas na tradição. Nessa perspectiva, situa-se o texto Húmus - poema contínuo, do escritor português Rui Torres, que, além das várias mídias – som, imagem, texto – de que dispõe na produção do poema, estabelece diálogo com duas obras anteriores: o romance Húmus, de Raul Brandão, publicado em 1917, e o poema homônimo de Herberto Helder, de 1967. Nossa proposta, então é, a partir do trabalho de Torres, pensar como os meios digitais afetam a relação com o texto literário impresso, seja no ato da criação ou no da leitura, e discutir como se operam a retomada e o diálogo com as obras do passado. Nossa análise se fundamenta nos Estudos da Intermedialidade, de Irina Rajewsky, bem como no conceito de remediação, de Bolter & Grusin. Tomamos também a ideia de escrita palimpséstica, tal como a formula G. Genette, e a reflexão de Borges sobre a releitura da tradição, entendendo que, ao se apropriar de um texto, o poeta promove um desvio em relação ao texto precursor.
Conductive Polymer/SiO2 Composite as an Anticorrosive Coating Against Carbon Dioxide Corrosion of Mild Steel. A Simulation Study
Authors: Avchukir K. , Burkitbayeva B.D.
Published: December 2020

In this work corrosion of mild steel affected by carbon dioxide was studied using a simulation model developed by Nordsveen M. and Nesic S. Using this comprehensive model of the uniform corrosion made possible to predict of corrosion rate of steel in the carbonic acid medium and the influence of different conditions on the anticorrosive property of coated electrode has been investigated. 1D model of corrosion process includes Butler-Volmer and Tafel equations and takes into account both the kinetics of anodic dissolution of an iron and electrochemical discharge of carbonic acid, water and hydrogen ions. The model has been created in COMSOL Multiphysics software and further improvement of this model allowed studying the influence of parameters such as solution composition, the partial pressure of CO2, temperature and flow velocity of the solution on the corrosion rate of the steel. The results of numerical simulation demonstrate that the use of conductive polymerpolypyrrole/ SiO2 composite as an anti-corrosive resin coating reduces the corrosion rate of mild steel by 7 times or more, depending on pH, temperature and flow rate. Furthermore, increasing of flow velocity from 0.1 to 10 m/s affects to the removal of corrosion products from the surface of mild steel and as a result corrosion rate raises from 0.3 to 0.45 mm/year at a temperature of 80 °C and pH=4.

Published: December 2020

According to WHO, indoor and/or outdoor air pollution is one of the main contributors to over two million premature deaths each year. As most of the human’s life is spent indoor, Indoor Air Quality (IAQ) - an air quality inside of a building represented by pollutant concentration and thermal condition - is one factor that needs to be concerned to sustain healthy living. In this research, we developed an Internet of Things (IoT)-based IAQ monitoring device using low-cost sensors that measure the concentrations of Carbon Dioxide (CO2), Oxygen (O2), and Particulate Matter (PM2.5). This device connects to an Android application to further observe these parameters inside two practicum laboratories in Telkom University, Bandung, for a total duration of six weeks. The location is surrounded by urban air pollution, particularly industrial activities, and residential waste burning. We also have sites of outdoor air quality monitoring system for simultaneous measurement. The environmental conditions were observed under no human activities, human intervention, and indoor plants' influence (i.e., Dieffenbachia sp.). Results show that pollutant concentrations are considerably influenced by outdoor conditions, occupancy level, and ventilation rate. Indoor plants can reduce CO2 concentrations inside the room (21-47%). On the other hand, there is no clear evidence that PM2.5 mass concentrations were affected by human activities. The bigger particles (PM >2.5 microns) probably were the ones induced by occupants during practicum. Therefore, using low-cost sensors is trustworthy to monitor IAQ for a better quality of life.

The modified logistic regression (Morais-rodrigues et al., 2020) was used to classify breast cancer subtypes using all microarray database samples. A stabilizing term, that allows the assignment of values to αi∗ parameters, was inserted in this methodology and with that, during the derivation there is the insertion of the identity matrix (positive defined) which added to the other semi-defined part, results in a positive defined matrix, which has auto values > 0 and determinant > 0, square matrix is full rank if it is reversible (determinant > 0) , which results in a single solution. In the results it was observed that some genes were located topologically in the extremities after plotting the parameters αi∗, these parameters are related to the expression of genes with a suppressor or oncogenic profile  in breast cancer, and with genes not studied yet. Some of these genes were found in gene regulatory networks from the search of Iglesias-Martinez et al. (2016), and S-score values were associated with these genes, negative value S-score is indicative of tumor suppressing or reduced gene activity and the positive value S-score is indicative of oncogene or increased gene activity (de Souza et al., 2014). In view of the importance of these genes, this article provides a literary review of them.
