Hybrid RF/FSO communication system in dust attenuation link
Authors: Hamoudi Zainab A. , Ali Mazin Ali A.
Published: July 2023

FSO systems have unlimited bandwidth and unlicensed availability, which makes them an attractive low-cost solution. Because the wavelength of the signal is close to the diameter of the dust particles, they have an impact on the FSO link by reducing its availability and causing its interruption. To solve this, a hybrid system of two RF/FSO links to avoid transmission interruption is necessary because the effect of dust on the RF links is slight because of their large wavelength compared to the size of the dust particle. In this paper, hybrid RF/FSO links are simulated and investigated under dusty conditions. The BER, Q-factor, and data rate are calculated for 2, 10, and 25 GHz of RF link. Besides, the wavelength of 1550 nm is used for the FSO link. The results produced at 10 and 25 GHz are suitable for wireless communication. So, it is the best link to use as a backup link with the FSO system. The performance of 1550 nm is poorer. The lower frequency of the RF link (2 GHz) has a similar link with the FSO. Under different dust conditions, the transmission rate is enhanced by a 25 GHz link. The link distance is reduced by decreasing the visibility of the weather.

Published: July 2023

Many dermatological diseases still do not have an adequate treatment, such as melanoma. The treatments are usually lengthy, complex, with low cure rates and with severe side effects. This leads to low patient compliance, generating recurrence and/or worsening of the disease. Ethosomes, which are phospholipid-based vesicles containing ethanol, have shown great potential as drug delivery systems for the treatment of melanoma and other skin diseases. The unique structure of ethosomes allows for enhanced skin penetration and efficient delivery of therapeutic agents to the target site, improving the efficacy of treatment. The use of ethosomes in melanoma treatment holds promise for overcoming the limitations of conventional therapies, offering the potential for improved patient outcomes, reduced treatment duration, and minimized side effects. In this mini-review we present the advances, challenges, limitations and advantages, and future perspectives of the use of ethosomes in the treatment of the melanoma.
What’s in a Bottle? Morandi’s Art and Ordinary Aesthetics
Authors: Monteiro Luis
Published: July 2023

This article’s assumption is that ordinary aesthetics does not necessarily imply a distancing from art and artists; rather, it can benefit from the input of creators when they use everyday scenes or objects as their theme. This approach focuses on the practice of twentieth-century Italian painter Giorgio Morandi, who depicted compositions of common objects such as bottles, jars, and vases. Through Morandi’s meditative and artistic search, these objects are given value and aesthetic elevation in his paintings. Thomas Leddy’s aesthetics of everyday life will also be called upon in my analysis, insofar as the author recognizes a continuity between the ordinary and the extraordinary, through auratic experiences. If Morandi discovers the extraordinary in the trivial, this is achieved through a gradual process of selection regarding the objects he favoured, which allows for the interaction of various levels of aesthetic intensity. Morandi’s objects and models and their preparation suggest a circulation between aesthetic degrees that, in turn, suggests a timeless “language of things” fixed through the discourse of the paintings. Along these lines, it will be necessary to address the enchantment related to common things, a mesmerizing presence of which we became more aware through Morandi compositions.
Die Freiheit nach dem Tod
Authors: Heinicke Julius
Published: July 2023

Das Wissen um den Akt des Sterbens, der stets mit einer Form der Verwandlung oder Transformation des leiblichen Körpers in der Phase des „Danach“ einhergeht, beschert, so die These, der Menschheit seit jeher einen grenzenlosen Raum und kann womöglich als Ursprung jeglichen kulturellen und ästhetischen Ausdrucks gelten. Das „Danach“ bietet aufgrund seiner Dimension des „Nichtwissens“ eine größtmögliche Freiheit an Spekulationen. Der Artikel geht dieser Freiheit nach und beschreibt zunächst die vielfältigen religiösen und politischen Versuche, sie zugunsten der Stärkung eigener Macht und Deutungshoheit zu beschränken. Sodann widmet er sich dem Potenzial künstlerischen, ästhetischen und kulturellen Schaffens, dem Nichtwissen einen Raum zu geben. Gegenwärtig stellt sich jedoch wie Frage, wie die „Freiheit der Kunst“ einerseits geschützt und andererseits ein verantwortungsvoller Umgang mit ihr garantiert werden kann. Dem Paradoxon zwischen ästhetischer Grenzenlosigkeit und gesellschaftlicher Einschränkung kann, so die These, allein das Wissen über das Nichtwissen des „Danach“ begegnen. Mehr noch, es vermag eine für heutige Herausforderungen vielversprechende Wirkmacht zu entfalten, die abschließend anhand von vier kulturpolitischen Prämissen vorgestellt wird.
Von der Freiheit zur Befreiung, eine iberoamerikanische Perspektive
Authors: Mate Reyes
Published: July 2023

In der lateinamerikanischen Welt wird Freiheit als Befreiung verstanden. Worin liegt der Unterschied? Er liegt in dem Bewusstsein, dass Freiheit entsteht, wenn der Einzelne und die Gesellschaft die Widerstände überwinden, die sie behindern. Die zentrale Bedeutung des Begriffs der Befreiung in Vergangenheit und Gegenwart steht in engem Zusammenhang mit der Geschichte der kolonialen Abhängigkeit und der Emanzipation aus dieser. Die Größe des Romans Hundert Jahre Einsamkeit des Nobelpreisträgers Gabriel García Márquez besteht darin, dass er zeigt, wie die Kolonialisierung der Neuen Welt dazu führt, dass europäische Sichtweisen auf die Geschichte und Vorgeschichte Lateinamerikas übernommen werden. Um sich in der von den westlichen Ländern dominierten Geschichte zu verorten, mussten die lateinamerikanischen Länder ihre Sichtweisen verleugnen und sich an die Vorstellungen und Perspektiven der Eroberer und ihre Kulturen assimilieren. Dieses „Vergessen“ ist der Grund für viele spätere Schwierigkeiten und Identitätsprobleme. Um zu sich selbst zu kommen und sich selbst zu verwirklichen, gilt es, sich von diesen kolonialen Zumutungen zu befreien.
A Dive into the Depths of Human Intimacy
Authors: João Name José , Baitello Junior Norval
Published: July 2023

This article is a report on ongoing field research and the exponential growth of the environment in which sex workers, prostitutes, call girls, and escorts operate. We look at the complexity of the conditions of such work and consider the socio-psychological and media vectors that make up the context from which its actors and stereotypes emerge. With the explosion of websites offering virtual or real sex, there is also a continuation of oppressive and violent male practices in this sector, restricting the freedom of choice for women who work professionally in this field. These practices reproduce the power relations and the exclusion that has always been present in society, and are also now more diffuse as virtual reality has come to play an important role in social practice.

Authors: Antczak-Komoterska Anna , Sołtysińska Maria Małgorzata , Grączewska Natalia , Krajewska Karolina , Haor Beata , Kochman Dorota
Published: July 2023

Introduction. According to the conducted research, the workload results from the general involvement in the undertaken activities. It can therefore be seen that the greater the involvement, the greater the burden, and thus the greater impact on the health of both the physical and mental nurse/caregiver. It should be noted that many factors affect the degree of the load.
Aim. The main aim of the conducted research was to assess the degree of workload of nursing teams while caring for elderly people diagnosed with a neurological disease.
Material and Methods. The study was conducted in the Provincial Specialist Hospital in Włocławek on a group of 120 randomly selected people (nurses) caring for an elderly person with a neurological disease. The study used the method of diagnostic survey, using the survey technique. In order to obtain an answer to the main objective of the research, a questionnaire was constructed and standardized research tools were used — ADL, IADL and the Negative Care Impact Scale included in the COPE-index questionnaire.
Results. The study showed that with the increase in seniority in the role of a nurse/carer in the care of the elderly, there is an increase in physical strain, weakening of relations with friends, a significant impact on family relationships and a decrease in satisfaction with the role. The data obtained indicate that a small percentage of nursing teams use equipment such as a lift or rollers for transfer. The study clearly shows that the degree of independence of an elderly person with a neurological disease has a significant impact on both the mental and physical health of the nursing teams taking care of them.
Conclusions. There is a relationship between seniority and job satisfaction. People with the longest work experience do not feel satisfied. Nursing teams do not fully use material and human resources while performing their role of caring for elderly people, which may result from various reasons (lack of knowledge, lack of skills, limited access to equipment, lack of willingness for cooperation and helping others). This has an impact on the level of physical and mental burden of nurses. The degree of independence of the ward has a significant impact on the level of physical and mental burden of the nurse. With the increase in dependence of the ward, the degree of burden on nursing teams increases. (JNNN 2022;11(4):167–173)
Golden Ages Hasidic Singers and Cantorial Revival in the Digital Era
Authors: Lockwood Jeremiah
Published: July 2023

Golden Ages is an ethnographic study of young singers in the contemporary Brooklyn Hasidic community who base their aesthetic explorations of the culturally intimate space of prayer on the gramophone-era cantorial golden age. Jeremiah Lockwood proposes a view of their work as a nonconforming social practice that calls upon the sounds and structures of Jewish sacred musical heritage to disrupt the aesthetics and power hierarchies of their conservative community, defying institutional authority and pushing at normative boundaries of sacred and secular. Beyond its role as a desirable art form, golden age cantorial music offers aspiring Hasidic singers a form of Jewish cultural productivity in which artistic excellence, maverick outsider status, and sacred authority are aligned.
Gambiarra and the In(ter)dependent Condition
Authors: de Paula Bibiana da Silva , Luersen Eduardo
Published: July 2023

This article analyzes the relationships of interdependence between musicians and natural or artificial agents of their environment. Considering processes of recycling and refunctionalization of materials with artistic purposes, such relationships are observed in the construction of instruments involving gambiarra in their manufacturing, with a focus on the specific case of an experimental music duo, Senyawa. The paper is theoretically and epistemically grounded in studies focusing on gambiarra, media and ecology, and media archaeology. The methodological procedures encompass analyses of instrument manufacturing processes developed by Wukir Suryadi, one of the members of Senyawa. As a contribution to studies of sound and culture, the article concludes that, through creative practices involving obsolete media materialities, gambiarra processes allow us to observe the continuous relationships between technology and nature in the design and manufacturing of technical artifacts.

Authors: Kusumawati Yuli , Widyawati Widyawati , Dewi Fatwa Sari Tetra
Published: July 2023

The main factors increasing the risk of depression are pregnant women’s lack of knowledge about recognizing signs and symptoms, early detection, and prevention efforts. The purpose of this study is to examine the impact of mental health education on pregnant Indonesian women’s knowledge and self-efficacy during the COVID-19 pandemic. A quasi-experimental study was conducted. Pregnant women in four Surakarta primary health care facilities received antenatal care using Basic Emergency Obstetric Neonatal Care. The inclusion criteria for the sample were 127 pregnant women with a gestational age of 24-36 weeks, no family history of mental disorders, a singleton pregnancy, and participation in the intervention from beginning to end. The study excluded pregnant women who experienced complications during their pregnancy. Sample sizes for the intervention and control groups were 67 and 60 pregnant women, respectively. Personal psychoeducation intervention was provided by trained midwives during antenatal care. During the intervention, materials were presented in modules, and videos were shared through WhatsApp groups and discussions. The Edinburgh Postpartum Depression Scale was used to assess depressive symptoms. The data were analyzed using the paired t-test and independent t-test. Following the intervention, the mean score for knowledge and self-efficacy increased. Depressive symptom scores decreased following the intervention and were significantly different from the control group. Mental health education interventions for pregnant women using modules and videos can improve pregnant women’s knowledge and self-efficacy in preventing antenatal and postnatal depression.

Authors: Istek Abdullah , Aydemir Deniz , Aksu Soner
Published: July 2023

The objective of this study is to evaluate the effect of décor paper and resin type on physical properties, mechanic properties, and surface quality properties of particleboards coated with décor papers impregnated by using different resin. White oak, New wenge and common maple pattern decor papers impregnated with urea formaldehyde (UF), melamine formaldehyde (MF) and urea-melamine formaldehyde (UF+MF) were used as coating materials. Particleboard surface was laminated with these coating materials by hydraulic press. As a result, specimens coated with MF-impregnated papers showed better performance than those coated with UF and UF+MF-impregnated papers. Resin type and paper pattern affected the physical, mechanical (with exception of tension strength), and surface properties (especially cigarette burn and abrasion) of coated particleboards. Physical and mechanical properties of coated particleboard were significantly improved compared to non-laminated particleboards. It was found that paper pattern affected the surface properties, such as impact, scratch, and abrasion, resistance to staining and cigarette burn. However, it did not change the cracking and steaming properties of the coated samples. After the coating process, it was determined that cigarette burn, abrasion, impact, and scratch performances were among 1 to 3 grade, lp:10-35, Fp:210-340/100-150, and 2 to 5 grade, respectively.
Natural durability and phenolic content in dried Scots pine heartwood
Authors: Sehlstedt-Persson Margot , Karlsson Olov
Published: July 2023

The durability of Scots pine heartwood has previously been shown to be affected by the industrial drying process of sawn lumber. The durability of heartwood from boards dried at temperatures between 20°C-110°C was studied by measuring the mass loss in a decay test with a brown rot fungus (Coniophora puteana), and the concentration of total phenolics was measured according to the Folin-Ciocalteu (FC) assay. The relation between mass loss and phenolics in dried heartwood showed a weaker negative correlation at lower levels of phenolics as compared to the strong relationship found in a study on heartwood from standing Scots pine trees. Mass loss in dried heartwood showed a weak negative correlation to density. Heating of extractives-rich green sawdust under moist conditions resulted in a reduction of phenolics with temperature up to 180 oC and with increasing time. The concentration of phenolics in heated, green sawdust was higher in extractives-rich pine heartwood than in heartwood with a normal extractives content.

Published: July 2023

Oxygen delignification can be considered to be the most important part of TCF and ECF bleaching sequences because it allows for cleaner production of pulp. During the process, oxygen gets one electron from lignin in the alkaline condition to form some active oxygen species (AOS), including a superoxide anion radical (O2-•), which is crucial for lignin degradation without damage of carbohydrates. The reaction of O2-• on cellulolytic enzymatic lignin (CEL) from Masson pine was studied. The change in active hydroxyl content after reaction with O2-• was investigated using 31P-NMR. After reaction, the aliphatic hydroxyl and uncondensed type phenol hydroxyl contents decreased, but the content of carboxylic group increased in Masson pine lignin. Through the analysis with HSQC-2D13C-H technology, β-O-4 linkages could be cleaved by O2-•, but β-β and β-5 linkages were observed to be more stable; benzaldehyde and cinnamic aldehyde structures could be oxidized to carboxylic acids by O2-•. Guaiacyl units in lignin were more easily degraded than p-hydroxybenzene units.

The Sustainable Development Goals (SDGs) call for all countries to achieve 17 broad development goals by 2030. One of the ways to achieve good health and well-being is health awareness to prevent diseases through high-quality education. This study aims to measure environmental awareness among Applied Science Private University (ASU) students in Jordan to attain good health and well-being. A cross-sectional questionnaire was conducted in 2022 containing 11 statements to measure students' health knowledge that contributes to disease prevention and its relationship to environmental pollution. The 11 statements within the study were subjected to mean and standard deviation summary analysis. The Mann-Whitney test was applied to determine students' environmental awareness to reach well-being concerning gender, age, and college. The sample involved 151 students from (ASU), 32.5 % of them are male students while the remaining (67.5 %) are females; 57 % are from scientific colleges while the remaining (43 %) are from humanities colleges, and 53 % are with ages greater than or equal to 20 years old, while the remaining (47 %) are with ages less than 20 years old. According to the results, students had a medium environmental awareness to reach well-being with a mean value of 2.1427 and a value of 0.30014 as standard deviation. Male students had higher environmental awareness reach well-being than females. Humanities colleges students had greater environmental awareness to reach well-being than scientific colleges students.
Integrating Mathematical Modeling of Real-Life Problems: A Contextualized Approach to Developing Instructional Material in Basic Calculus
Authors: Pelemeniano Airish P. , Siega Marvin H.
Published: July 2023

This study focuses on the creation of contextualized educational materials for senior high school basic calculus that integrates mathematical modeling with real-life problems. The research follows the ADDIE model employing only three stages: analysis, design, and development (ADD). In the analysis phase, the researcher determines the level of modeling competency, self-efficacy, and appreciation of the learners using the Assessment of the Modeling Skills (RAMS), Indices for Mathematical Modeling Self-Efficacy Scale (IMMSES), and the Indices for the Level of Appreciation of Mathematical Modeling (ILAMM) respectively. The results from the previous phase were considered in designing and developing contextualized instructional material that aligned with the concepts of didactical situations and mathematical modeling. Quantitative data analysis includes descriptive statistics to determine the level of modeling competency, self-efficacy, and appreciation of the learners and the assessment of the teachers on the mathematical modeling activities. This study also reveals that the learner’s lack of prior knowledge in algebra and trigonometry contributed to the difficulty in solving real-life problems in Basic Calculus. Moreover, teaching materials are limited only on problem-solving and formative assessment. With this, the researchers designed and developed instructional materials that incorporate a variety of resources, including problem scenarios, data sets, visualizations, and technology tools, to facilitate students' exploration and analysis of the modeled problems. Ultimately, it aims to enhance students' understanding and engagement by providing them with meaningful and practical applications of the subject matter.

Вплив катіонних поверхнево-активних антисептиків на розчинення природного поліфенолу куркуміну у водних середовищах
Authors: Ліпковська Н.О. , Барвінченко В.М. , Картель М.Т.
Published: July 2023

Встановлено закономірності солюбілізації, таутомерних перетворень і зміни спектральних характеристик природного поліфенолу куркуміну в разі розчинення у водному середовищі катіонних ПАР — антисептиків етонію та декаметоксину залежно від їх концентрації в розчині. Показано, що в організованих міцелярних середовищах цих катіонних ПАР куркумін розчиняється в енольній формі, його розчинність збільшується на два порядки. Методом розчинності визначено величини констант зв’язування куркуміну з міцелами етонію (lgКзв = 4,39) та декаметоксину (lgКзв = 4,47). В доміцелярних розчинах довголанцюгового катіонного ПАР етонію до появи звичайних класичних міцел куркумін розчиняється у водному розчині переважно в кетонній формі і його концентрація зростає у 150 разів за рахунок утворення ним розчинних супрамолекулярних комплексів. На відміну від етонію, в доміцелярних розчинах коротколанцюгової катіонної ПАР декаметоксину практично не відбувається поліпшення розчинності та зсуву рівноваги кето-енольної таутомерії куркуміну. Виявлені закономірності мають вагоме наукове і прикладне значення для розробки лікарських препаратів на основі таких систем.

Методами рентгенівської порошкової дифракції встановлено основні закономірності впливу ізовалентного заміщення атомів А-позиції в шаруватій перовськітоподібній структурі індату BaNd2In2O7 на механізми утворення двошарових фаз типу BaNd2–хSmхIn2O7 (х = 0, 1, 1,6 та 1,8) послідовною термообробкою шихти спільно закристалізованих солей. Показано, що стадійність механізмів утворення і характер послідовності фазових перетворень визначається як складом, так і ступенем заміщення атомів неодиму. Встановлено, що формування високовпорядкованої шаруватої структури BaNd2–хSmхIn2O7 (х = 0 та 1) відбувається за температури Т > 1570 К шляхом структурної трансформації проміжного тривимірного дефектного перовськіту загального складу (BayLnz)InO3–δ із статистичним розподілом атомів Ba, Ln та оксигенових вакансій. Формування двошарових BaNd2–хSmхIn2O7 (х = 1,6 та 1,8) відбувається двома шляхами: як взаємодією дефектного ромбічного перовськіту (BayLnz)InO3–δ з проміжною фазою Ba(In,Sm,Nd)O4, так і шляхом структурної трансформації дефектного перовськіту (BayLnz)InO3–δ. Визначено оптимальні умови синтезу однофазних BaNd2–хSmхIn2O7 з двошаровою перовськітоподібною структурою.

Для розрахунку вільної енергії взаємодії та визначення амінокислотних залишків процедурою молекулярного докінгу було застосовано програму iGEMDOCK v2.1, досліджувані ензими — комплекси ізоформ CYP із референтними лігандами (1A2 (2hi4), 2B6 (5uda), 2C8 (2nnj), 2C9 (1og5), 2C19 (4gqs), 2D6 (4wnu) та 3A4 (5te8), молекулами-субстратами для кожного ізоензиму вибрано відповідно фенацетин, бупропіон, амодіахін, диклофенак, S-мефенітоїн, буфуралол та мідазолам з тестостероном відповідно.

Пропоксазепам має досить високі показники вільної енергії взаємодії з усіма ізоформами CYP (8,15—9,8 ккал/моль), однак є різниця в кількості спільних амінокислотних залишків, що беруть участь у взаємодії зі специфічними субстратами. За різницею енергії зв’язків можна припустити, що найменший конкурентний (інгібувальний) ефект пропоксазепам може мати відповідно на ізоформи 3A4 (із субстратом тестостероном) та 2D6. Аналіз взаємодій пропоксазепаму з різними ізоформами CYP з урахуванням їх індивідуальних субстратів дає підставу припустити можливість конкурентної взаємодії для 1А2, 2С19 та 2С8 і, меншою мірою, для 2С9, 3А4 та 2B6. Також можна очікувати, що пропоксазепам може бути субстратом для досліджуваних ізоформ цитохрому.

Purpose. Provide a comprehensive productive and biological characterization of carps of the new selective breeding type, the first generation — Nesvich zonal type in the first year of life. Methodology. The study was conducted in fish farms of the Lviv and Volyn regions of Ukraine. The material for the study were young-of-the-years and age-1 carps of Nesvich zonal type. The main productive and biological parameters were studied during test harvests during the growing season according to generally accepted methods in fish farming. The external evaluation of the experimental groups was carried out according to the following parameters: body weight and length, body height, body girth. Measurements were made with a centimeter tape with an accuracy of 1 mm. Individual weighing was carried out on electronic commercial scales with an accuracy of 1 g. Based on the results of the measurements, the main exterior parameters were analyzed and determined: body length to girth ratio, body length to height ratio, body length to head length ratio. Findings. The study showed that young-of-the-year carps of Nesvich zonal type were characterized by high productive parameters. The average individual weight was 39.3–55.0 g for framed and 42.0–67.9 g for scaled forms. According to winter hardiness, with the survival rates in the range of 80.5 - 84.5%, scaled forms of carp had the weight loss of 8.6 - 10.3% while framed carps had 9.1 - 9.8%. Originality. The results of the study on growing the first selection generation of young-of-the-year and age-1 Nesvich carp, which will be submitted to the approval of this zonal type as an intrabreed type of Ukrainian framed and scaled carp breeds, are provided. Practical value. The results of the analysis of productive and biological parameters will allow providing recommendations on the use of this zonal type as a new type for commercial growing. Key words: carp, scaled and framed form, zonal type, generation, exterior, weight, condition factor.

Currently, the discussion on the development of a national space launch system and the feasibility of spacecraft launching from its own territory is being held in Ukraine. One of the main obstacles to the deployment of the launch site in Ukraine is the dense population on its territory and the inability to ensure safety in the launch vehicle flight phase due to the hazard of separating parts impact on the neighbouring countries during the nominal mission and launch vehicle (its fragments) impact in the event of an accident. To date, the project of the promising Cyclone-1M space launch system featuring a three-stage lightweight ILV has been developed in Yuzhnoye State Design Office, which will allow comprehensive tackling of the flight safety issue. It features the launch site in the Kherson region with the flight trajectories routed southward to place the spacecraft into the sun-synchronous orbit. The article provides a theoretical and computational safety analysis during the nominal mission of the Cyclone-1M ILV and in the event of an accident in the flight phase, as well as recommendations for flight safety improvement. It is shown that the proposed technical and organizational solutions ensure the fulfillment of flight safety requirements for the population and facilities on the territory of Ukraine, adjacent to the launch point, on the territories of Turkey and African countries, which fall within the emergency ILV impact areas, as well as for vessels in the waters of the Black and Mediterranean Seas. Hazardous zones of the Mediterranean Sea for vessels in the areas of the fall of separating parts were calculated. To ensure the safety of vessels in the Mediterranean Sea, it is required to remove them from the hazardous zones during the ILV launch. The resulting total collective risk for the population within the emergency ILV impact area is 3.4610–5, which ensures the fulfillment of the international flight safety requirements. Now the main problem remains the ILV flight over the territory of the Black Sea State Biosphere Reserve, where an emergency ILV may fall in the event of an accident in the initial flight phase.
Memorias migrantes, exclusión y pertenecia, el caso de Goiânia
Authors: De Bessa Suzete
Published: July 2023

Este artículo busca resaltar las dinámicas de las memorias sin lugar y sus consecuencias en los conflictos y potencialidades en Goiânia, identificando cómo estas resultan en exclusión y pertenencia, e implican la valorización de la experiencia y la voz de migrantes en la ciudad. Con ese fin, pretende presentar conclusiones de investigaciones en arquitectura y urbanismo iniciadas en 2019 en la Universidad Federal de Bahia que fueron presentadas a investigadores de posgrado, siendo construidas concomitantemente con el desarrollo de proyectos de extensión con migrantes y refugiados venezolanos en Goiânia y su región metropolitana, en el Estado de Goiás. El trabajo en su momento pretendió, a través de una investigación semiestructurada, establecer un diálogo sobre la complejidad de la elaboración de memorias en el contexto de las migraciones, considerando el momento político, tratando de aplicar tales diálogos al escenario local específico y sus perfiles migratorios diversificados. Frente a una investigación incipiente, algunas teorías movilizadas resultaron imprecisas y algunos autores absolutamente necesarios para el diálogo fueron eximidos del debate. Hoy, a tres años del inicio de la investigación, el cual se dio con un solo núcleo familiar, y luego de un paréntesis dedicado a la maduración y profundización de la práctica metodológica, se amplió a otros núcleos o familias migrantes y refugiadas en Goiânia. De esta forma, se busca revisar lo que se propuso en el primer trabajo, con el fin de replantearlo y sus conclusiones a partir de cuidadosa descripción metodológica, posicionando autores e investigadores de gran relevancia en su construcción.
Viviendas vernáculas: Formas de hábitat en la costa de Ecuador
Authors: Peralta Coello Angélica Brigitte
Published: July 2023

Este artículo supone un avance preliminar de un estudio que se propone analizar las condiciones de habitabilidad y materialidad de las viviendas rurales en la costa de Ecuador, cuya importancia nace de la poca atención dada como objetos de estudio, a pesar de que el 37% de la población reside en áreas rurales. La falta de información sobre modelos de viviendas adecuados para este sector es evidente, por lo que este estudio tiene como objetivo analizar las características más relevantes de las viviendas rurales tradicionales en relación con su ubicación y los materiales disponibles en el entorno. Además, se analiza la herencia recibida en este contexto, comprenderla, cómo aprovecharla, y aplicarla en la construcción actual. El resultado no es proponer un modelo de vivienda específico, sino más bien resaltar la importancia y poder considerar estos aspectos en el desarrollo de modelos de vivienda sostenibles, funcionales y acorde a su contexto.
