Abstract Zoochory is a fundamental process that can be the main mechanism for seed and plant dispersal for many species. Mammals of the Carnivora order are among the most important dispersing agents; however, little is known regarding the role of canids as seed dispersers. Although the maned wolf (Chrysocyon brachyurus) has a potentially important role in seed dispersal, given its relatively high consumption of fruits, few studies have investigated the germination rate of ingested seeds. Here, we used seeds removed from the feces of two captive specimens (maned wolf treatment) and those directly collected from unconsumed fruits (control) in germination essays to evaluate the germination rate and emergence velocity index (IVE). We used mature fruits from five species of trees in the Cerrado and Atlantic Forest in a 5 (species) × 2 (method of seed collection) factorial arrangement. The passage of seeds through the digestive tract of the maned wolf favored the germination of Genipa americana and Psidium guajava, delayed germination of Psidium cattleianum, and maintained the germination of Plinia cauliflora and Ficus obtusifolia. Our results revealed that germination occurred for all tested plant species consumed by the maned wolf; therefore, this canid species has high dispersal potential and can be an important ally in the restoration of the Cerrado and Atlantic Forest-Cerrado contact zone ecosystems.

Authors: Delgado Ángel Acuña
Published: August 2023

Resumen Los Huaorani, pueblo indígena de la Amazonía ecuatoriana, fueron contactados en 1956 y sometidos desde entonces a un intenso proceso de “civilización” e “integración”. Si bien las prácticas homicidas se hallaban muy presentes en su modo de vida, de prácticas suicidas no se tienen constancia, circunstancia que ha cambiado notablemente desde comienzos del siglo XXI, al aumentar éstas progresivamente y alcanzar cifras realmente alarmantes en la población juvenil. En base al trabajo etnográfico realizado, abordamos el suicidio huaorani en el área de Toñampari desde una óptica cultural. El esquema interpretativo aplicado ayuda a entender, no solo el contexto y los motivos desencadenantes de los actos suicidas, sino muy especialmente los factores esenciales para su comprensión. Entre las conclusiones dicho fenómeno es señalado como una más de las consecuencias del proceso de asimilación huaorani en la sociedad nacional ecuatoriana.
A antropologia como ofício feito de reencontros, perdas e curas
Authors: Vianna Adriana
Published: August 2023

Resumo: O texto aborda, sob forma de comentário a Textures of the Ordinary: Doing anthropology after Wittgenstein, de Veena Das, a complexidade do tempo etnográfico e suas relações com a escrita na obra da autora. Busca, dessa forma, destacar o quanto a atenção ao cotidiano e ao ordinário sublinhada pela antropóloga implica modos bastante singulares de registrar limites e compromissos de nossa atuação enquanto etnógrafas. Discute ainda que, em seu livro, a capacidade de “tolerar a obscuridade” implica movimentos de ordem ética e estética que se revelam na capacidade de retomar escritos anteriores, compor tempos heterogêneos e deixar marcadas hesitações reflexivas que produzem aberturas únicas na compreensão do trabalho antropológico como algo marcado por perdas e reconfigurações.

ABSTRACT Objective: To analyze the temporal and spatial distribution of polio vaccine coverage in Brazilian states. Methods: An ecological time series study was conducted using data from the National Immunization Program Information System. The analyzed period was from 1997 to 2021. Joinpoint software was used to calculate the annual percentage change and average annual percentage change through regressions. QGIS 3.10.7 software was used to construct thematic maps. GeoDa 1.20.0.10 software was used to estimate spatial autocorrelation using the Global Moran's Index and Local Moran's Index. Results: National vaccine coverage in 1997 was 89.27%, decreasing to 61.32% in 2021. The trend analysis indicated an average annual decrease of 1.5% in polio vaccine coverage in Brazil. Across the country, 17 states showed a statistically significant reduction in the average annual percentage change rate. The highest average reduction rates in vaccine coverage among Brazilian states were observed in Amapá (−3.7%; 95%CI −6.0; −1.4) and Pernambuco (−3.3%; 95%CI −4.0; −2.5). In the spatial analysis, in Moran Global, a positive autocorrelation was identified in the years 2012 to 2021 (p<0.02), with an index value of 0.361, which means that geographically close areas tended to have similar levels of vaccination coverage. Conclusion: There was significant heterogeneity in coverage among states and a strong decrease trend in vaccination rates, which could facilitate the circulation of the poliovirus and pose a threat to the susceptible population.

O currículo do curso apresenta 11 disciplinas voltadas para o cuidado, e os alunos associaram disciplinas de cunhos sociais ao cuidado centrado na pessoa. As competências desenvolvidas destacadas foram empatia, compaixão, integridade e respeito, comunicação efetiva e anamnese, e obtenção de informações socioculturais. Ademais, os estudantes de ambos os cursos relataram contato escasso com outros profissionais de saúde. Conclusão: Os discentes avaliados apresentam diversas inseguranças, principalmente relacionadas às habilidades clínicas que exigem prática. Apesar disso, os estudantes de Medicina demonstraram maior apreensão de soft skills, o que pode facilitar a criação de vínculos com os pacientes e resultar na qualidade do cuidado.
Gap analysis and perspectives on body donation programs: experience report in Brazil
Authors: Lucas Bárbara de Lima , Rocha Andréa Oxley da
Published: August 2023

Abstract: Introduction: International recommendations reinforce the practice of voluntary donation for providing bodies for the training of health professionals, replacing the system of unclaimed bodies in medical courses (MC). Experience report: This work gathered information on Brazilian body donation programs (BDP), analyzed gaps and difficulties to the effectiveness of body donation, and proposed strategies to expand the information offered on the registration of participants in BDP and the effectiveness of the donation. Discussion: In Brazil, there are 39 BDP - six in the Northeast, four in the Midwest, one in the North, 11 in the South, and 17 in the Southeast - and two committees for body donation. Documents may be easily available through registration during life as a participant in the BDP, but it does not guarantee donation. In general, Brazilian’s institutions receive the donated body along with the documentation. When the death occurs in the same city of the institution, it is possible to have the transfer of the body provided by partnerships with funeral services and the city hall. There is no fee to be paid or received either for registration during life or for donation after death. Conclusion: Although the legislation has regulated the donation of body in life since 2002, it is necessary to implement campaigns to inform about the donation, in addition to mechanisms that can promote speed in the deadlines for obtaining documentation for the purpose of donating body for scientific purposes, the exemption of notary fees and the possibility of transporting the body donated with no fees by funeral home of municipal governments. The MC support through the registration of the PDC as an extension activity collaborates to ensure ethical aspects related to the participation of donors in the living program, with regard to the treatment with respect and dignity of donors and their families.

Published: August 2023

ABSTRACT The methodologies for determining aquifer vulnerabilities are currently used as tools to support proposals for the groundwater protection, associated to water management resources and planning and territorial ordination activities. In this context, the objective of this present work is the vulnerability assessment of an aquifer system of interest located in the municipality of Ananindeua, the state of Pará. To this end, the following activities were executed: survey and systematization of pertinent information to existing wells in the municipality of Ananindeua-PA; determination of the constituent parameters of the GOD method and the hydrogeological values of hydraulic conductivity and hydraulic transmissivity; extrapolating the pertinent information for all the interest area aiming the spatialization of homogeneous zones by degree of vulnerability e, finally, the hierarchization of locations for the implementation of water supply systems. With the completion of this present work, it was verified that most part of the area of interest has an aquifer system classified as unconfined, mixed lithological extracts and distance from the top to the water table less than 20 meters. These information, associated with the pattern of land use and occupation, based on the study of hydrogeologic values, enables the subsidy for decision-making regarding the most appropriate allocation of preventive investments with basic sanitation infrastructure, in order to minimize or nullify the associated risks of contamination in the referred area. However, to a better support for an efficient decision-making from the public managers and the actions of other social actors involved in the use and management of groundwater in the locality, it must be provided other information and complementary studies.

Published: August 2023

Resumen Introducción Los años de universidad son un periodo de desarrollo crucial para la transición de la adolescencia a la adultez, por eso existe una creciente preocupación sobre la salud mental de los estudiantes. El COVID-19 puso en situación de vulnerabilidad a esta población, con aumento del riesgo de depresión, ansiedad o estrés. Objetivo Aunque los estudios sobre los efectos de la pandemia y sus consecuencias sobre la salud mental se publican de manera exponencial, existen pocos centrados en estudiantes de ciencias de la salud. Por ello, se enfoca esta temática en estudiantes de Grado en Terapia Ocupacional para explorar los efectos sobre la salud mental en la etapa de confinamiento inicial. Método Partiendo de la hipótesis de que el confinamiento ha podido poner en situación vulnerable a los estudiantes universitarios, se realizó un estudio cuantitativo longitudinal con estudiantes del Grado de Terapia Ocupacional en base a los cuestionarios General Health Questionnaire (GHQ-28), Patient Health Questionnaire (PHQ-9), Escala de Felicidad Subjetiva (SHS) y la Escala de Desesperanza de Beck. Resultados Los resultados mostraron una mejoría en las diferentes escalas entre los años 2019 y 2020, con relaciones estadísticamente significativas entre el estado de confinamiento y una reducción del riesgo de depresión a su finalización. Conclusiones Esta relación sugiere dudas sobre la temporalidad y la medición de los resultados siendo posible queque el confinamiento tuviera aspectos positivos en algunas de las dimensiones de la salud mental, dada su relación con la falta de aislamiento social en muchos casos, el establecimiento de rutinas y la reincorporación a la docencia presencial.

Published: August 2023

Abstract The objective of this work was to determine the storability of 'SCS417 Monalisa' apple fruit in response to harvest maturity, 1-methylcyclopropene (1-MCP) treatment, and storage atmospheres. Fruit quality was evaluated after two, four, six, and eight months plus one day or seven days in shelf life at 22°C. The controlled atmosphere (CA) and 1-MCP (1.0 μL L-1) treatments reduce fruit ethylene production and respiration, prevent rapid softening, and inhibit the incidence of scald-like symptoms, flesh browning, cracking, and fungal decay, in comparison with air storage . The combination of 1-MCP and CA provides additive benefits in firmness retention and in the reduction of the incidence of physiological disorders. CA and/or 1-MCP increase the risk of fruit developing wrinkly skin disorder. The loss of flesh firmness and acidity and the development of all physiological disorders and decay are higher in late-harvested fruit. The storage life of 'SCS417 Monalisa' apple is about two months in cold air and from six to eight months in cold CA, considering the time necessary to reach a flesh firmness of 53 N. The limiting factor for the long-term storage of 'SCS417 Monalisa' apple fruit under CA without 1-MCP is the development of physiological disorders and fungal decay.
FINITE DIFFERENCE METHOD BASED-NUMERICAL SIMULATIONS AND CAVITY TILTING ANALYSIS ON MAGNETOCONVECTION IN AN INCLINED PARALLELOGRAMMIC POROUS ENCLOSURE
Authors: Sankar Mani , Ravindra P. , Mahesha  , Makinde Oluwole Daniel , Sivaraj R.
Published: August 2023

This article numerically investigates the buoyancy-assisted convective flow and associated thermal characteristics in an
inclined parallelogram-shaped porous geometry containing heat source and sink of different lengths placed at various
locations. The left tilted wall has a hot source, and right tilted wall contains a cold sink, while the remaining regions of the inclined sidewalls are thermally insulated. The geometry is filled with fluid-saturated porous material and, in addition, an externally applied magnetic field (MF) has been supplied in lateral direction. The model equations
governing the physical processes involve Darcy's law for the momentum equations and energy equations to account
thermal variations. Using a stable and implicit finite difference methodology, these set of coupled and nonlinear partial differential equations are solved by reducing them to a system of linear algebraic equations. A wide range of numerical experiments are performed to determine the influence of various physical and geometrical parameters on the flow and thermal structure as well as thermal dissipation rate inside the geometry. Further, a suitable pair of inclination angles is found, at which maximum heat transport could be produced as compared to other combination of angles. Furthermore, an optimum size and location for the source-sink combination has been predicted which induces higher heat transport rates.

Authors: YILDIRIMYAN Nelli , TAŞ Ayşe , YILMAZ Selmi , ALTAY Mehmet Ali
Published: August 2023

Plasmablastic lymphoma (PBL) is a rare and aggressive non-Hodgkin lymphoma subtype associated with human immunodeficiency virus (HIV) infection. PBL is extremely aggressive and has a poor response to treatment. Clinically PBL resembles a periodontal disease, Kaposi sarcoma, or melanoma. Delayed diagnosis adversely affects the treatment and life expectancy. A 52-year-old male presented with a firm intraoral mass causing a slight elevation noticeable extraorally. Radiologically, loss of lamina dura around the first premolar and loss of both vertical and horizontal bone height around the dental implant replacing the second premolar were present. The biopsy confirmed a diagnosis of PBL. Further evaluation revealed that the patient was positive for HIV. The chemotherapy regimen included etoposide, vincristine, hydroxydaunorubicin, cyclophosphamide, and prednisolone, followed by an autologous hematopoietic stem cell bone marrow transplant. This article attempts to describe the clinical presentation and histopathological evaluation of PBL, and emphasize the paramount role of biopsy, early clinical suspicion, and correct diagnosis.

Knowledge Actors Engaging in “Everyday Planning” in Rapidly Urbanizing Peripheries of the Global South
Authors: Rao Dhananka Swetha
Published: August 2023

This article presents original research based on the premise that inclusive urban planning is about different types of knowledges coming together, a process that enables the participation of diverse knowledge actors. In India, the urgency of peri‐urbanization is reflected in the massive transformation and roaring real estate speculation that is being unleashed through the conversion of agricultural land into profit‐making urban zones. It is the praxeology of an everyday planning modality by actors that interpret the possibility of real estate speculation at different scales that drive the rapid emergence of the peri‐urban built environment around the metropolis of Bangalore in Southern India. At the outset, I present a conceptual framework that articulates territorial‐financial mechanisms at the macro‐level with the praxiology of planning actors and their networks at the meso‐level through spatial knowledges. Then I describe the methods used. In the empirical part, this article first describes a particular site at the periphery of the city of Bangalore. Then, I delineate the prescriptive knowledge given by the local planning law. I present the praxiology of the different knowledge actors that explain the modality of peri‐urbanization, followed by a discussion of the rationales of the actors that shape everyday practices of planning. Finally, I discuss how social workers could get more involved in the urban planning process and contribute to shaping more inclusive cities because of the profession’s grounding in principles and ethics that supports human well‐being and development in cities for people and not for profit.

Authors: Tenkovskaya Lyudmila I.
Published: August 2023

The relevance of the presented scientific research lies in the search for new data on foreign economic factors that can change world oil prices. The purpose of the study is to predict the prices of Brent crude oil based on the impact of new external economic factors, because the influence of supply and demand in the energy market has significantly weakened. To achieve the purpose of the study, the following tasks were solved: the theoretical foundations of the oil market were considered; a methodological approach to forecasting world oil prices was selected; as a result, an equation of multiple linear regression with independent variables in the form of indicators of the monetary policy of the United States is constructed, which makes it possible to make a forecast of world oil prices. The research involves general and special scientific methods: analysis, synthesis, monographic, statistical (graphical, tabular, centered moving average method, correlation and regression analysis). The scientific novelty of the study is as follows: based on statistical data on Brent crude oil prices, the effective federal funds rate of the US Federal Reserve, the M2 monetary aggregate in the US, the US dollar index, the US core personal consumption expenditure price index, the unemployment rate in the US for the period January 2014 January 2023, the equation is constructed multiple linear regression with the function of forecasting Brent crude oil prices. The above equation of multiple linear regression reflects the noticeable influence of the monetary policy of the US Federal Reserve System on world oil prices.

Published: August 2023

Сurrent geopolitical situation caused by unfriendly policies and sanctions against Russia by the states of Western Europe and the United States are the main reasons for the preservation and development of its state sovereignty, further improvement of innovation policy. In addition to the above, we can add the withdrawal of foreign companies from the Russian market, the ban on the supply of Russian high-tech products to foreign markets, the instability of the economic situation in domestic markets, in terms of import substitution of products and the reorientation of the Russian economy to the markets of Southeast Asia and China. Taking into account the modern transformation processes taking place in the domestic innovation market, a special role is assigned to the National Innovation System (NIS), consisting of a complex of interrelated business entities and institutional organizations interacting with each other in the process of innovation. The main element of the NIS is the state, which ensures the functioning and comprehensive support of innovation activities, as well as the formation of its strategic priorities, monitoring and coordination. The functions of state power to regulate economic development in the field of innovation, at the stage of formation and functioning of the NIS, are represented by organizational and financial support, the creation of incentives and conditions for the organization and implementation of innovative activities by business entities. With the targeted support of the state, the institutional structures of NIS are able to: increase the volume of modern high-tech technologies and high-tech industries, increase the output of competitive innovative products, stimulate the construction of innovative infrastructure and, in general, increase the level of development of the Russian economy. State regulation of innovation activity includes two management subsystems: the first one serves to ensure direct management of innovation activities, by virtue of its authority, and the second is intended for state regulation of innovations carried out by large corporations, high-tech enterprises, due to the importance of their activities for the state. As a scientific increment of the research results, the authors introduce the concept of institutional mechanism of NIS development, with the integration of key areas of development. The most important function of this mechanism is the scientific, industrial and technological sphere, using intellectual property and artificial intelligence technologies implemented in national technoparks, regional innovation centers, territories of advanced development of high technologies.
The role of the gross regional product in forming the standard of living in the regions of the Volga Federal District
Authors: Zotikov Nikolay Z.
Published: August 2023

Russia is characterized by differences in the level of development of regions, the quality of life of the population. According to the World Bank, Russia ranks third in the world in terms of regional inequality. The quality of life is one of the most important indicators recognized by the UN, characterizing the level of development of countries and nations. For Russia, the issue of assessing the quality of life in the regions under the current sanctions conditions is of particular importance. The purpose of the study is to study the role and significance of GRP in the socio-economic development of regions, in shaping the standard of living of the population, and to establish the relationship between GRP and other indicators. In the absence of a unified methodology, the RIRATING rating agency conducts a quality of life rating based on more than 70 indicators, but this list does not include GRP. The peculiarity of the author's approach: GRP is considered as the most important, initial indicator, on the value of which the standard of living of the population depends. The information base of the study was the data of the rating agency, methods were used: analysis and synthesis, grouping, comparison, collation, index, tabular, generalization, etc. The study established the impact of GRP on the quality of life. At the same time, high GRP values do not indicate the efficiency of the region's economy; they do not in themselves provide a high standard of living for the population, since the quality of life is a whole range of interrelated indicators.

Abstract: In this article, the author conducted an analytical study of existing tools for countering shadow economic phenomena in small and medium-sized businesses through SWOT analysis. To conduct a study of tools for countering shadow economic phenomena in small and medium-sized businesses through the use of SWOT analysis, the author selected four tools for state regulation of entrepreneurial activity, such as: strengthening product quality control; simplifying the procedure for registration of economic entities, reducing the number of activities requiring licensing and anti-corruption tools. The purpose of the study is to identify and establish the significance of strengths and weaknesses of various tools for countering shadow economic phenomena in small and medium-sized businesses. Also, in order to identify the resource base, the direction of measures to regulate the processes of shadowization, identify threats and opportunities for strategic decision-making in terms of choosing tools to counter shadow economic phenomena, a SWOT analysis of each tool separately was carried out and the main characteristics were identified. The study is planned and conducted in three stages. At the first stage, a SWOT matrix was compiled for tools to counter shadow economic phenomena. Next, a process of cross-evaluation of strengths and weaknesses, opportunities and threats was carried out. At this stage, the level of significance is estimated from the highest to the lowest, and then the assessment of each specified tool for countering shadow economic phenomena is calculated. And the third stage carried out an assessment of the significance of each factor, and further, these tools for countering shadow economic phenomena are ranked by the degree of significance from the largest to the smallest. In conclusion, based on the SWOT analysis, conclusions are formed about the degree of significance of the studied tools for countering shadow economic phenomena. The analysis of the tools for combating the shadow economy suggests that the most significant tools for countering the shadow economy include such as reducing the number of activities requiring licensing, as well as anti-corruption tools.

La presente investigación tuvo como intencionalidades: conocer y develar los aprendizajes significativos alcanzados durante el desarrollo del curso de investigación cualitativa en la Maestría de Educación: Mención Investigación y Docencia Superior en la Universidad Nacional Hermilio Valdizán, Huánuco, Perú, que de modalidad presencial pasó a modalidad virtual, debido a las restricciones del confinamiento impuestas por el gobierno peruano ante el avance del COVID-19 en el país. Mediante método investigación-acción en el aula, el estudio se desarrolló en la perspectiva metodológica cualitativa con dos grupos de estudiantes en el periodo académico 2020-I. A la par de las acciones pedagógicas, los investigadores-docentes recopilaron la información por la vía de testimonios focalizados escritos, registros de tareas, video conferencias, entre otras. Del proceso de sistematización de la información emergieron cinco categorías, siendo las de mayor saturación: i) leer y reflexionar es la clave y ii) el trabajo colaborativo como estrategia para el aprendizaje efectivo. Se concluye que en la experiencia de mediación y transformación digital del curso de investigación cualitativa fue significativa la preparación de los docentes en el conectivismo y la sustentación en el modelo educativo basado en la socioformación en la configuración de un entorno personal de aprendizaje, lo cual permitió que los estudiantes demostrasen un alto nivel de compromiso, desempeño y entendimiento de los principios epistemológicos y metodológicos implícitos en este tipo de investigación.

Este artículo explora los aspectos pedagógicos y psicológicos de la aplicación de las tecnologías de la información y la comunicación en las instituciones de educación militar superior de Ucrania en las circunstancias actuales. Se han mostrado las direcciones prioritarias para desarrollar la educación a distancia a través de las tecnologías de la información, incluyendo la plataforma MOODLE. La investigación identificó los resultados positivos de la aplicación de las tecnologías de la información en la educación bajo restricciones de cuarentena: un aumento de la eficiencia tecnológica de la educación a distancia debido al moderno software y hardware, un mayor nivel de accesibilidad y apertura de la educación, y una mayor individualización de la instrucción. Por otro lado, reveló también las desventajas: los materiales del curso almacenados en bases de datos carecen de una estructura bien organizada y no reflejan el nivel de conocimientos preexistentes de los cadetes; no hay una retroalimentación constante por parte del instructor; debido a la incapacidad de los recursos de Internet para hacer frente a la carga de tráfico que aumenta en la pandemia, son frecuentes los fallos técnicos durante el aprendizaje a distancia; los cadetes no están totalmente preparados para trabajar de forma independiente; aumento de la carga docente de los educadores, debido a la urgente necesidad de diseñar nuevos cursos de educación a distancia; dificultades en el desarrollo de materiales de curso de alta calidad para la educación a distancia; La aplicación de la tecnología de la información a menudo impide tener en cuenta el estado mental y la psicología de los alumnos y, por lo tanto, emplear adecuadamente un enfoque individual de la enseñanza. En general, se llega a la conclusión de que la aplicación de las tecnologías de la información en la situación actual permitió preservar los parámetros básicos del proceso educativo y proporcionó herramientas eficaces para la interacción de los participantes en el proceso educativo.

Optimization is essential in various fields such as finance, transportation, energy, and health care. However, solving real optimization problems, especially nondeterministic polynomial, requires considerable computational resources. Metaheuristics provide fast and cost-effective solutions to these problems. In this paper, eight state-of-the-art nature-inspired metaheuristic algorithms that have demonstrated excellent performance are compared in detail. In addition, a novel tournament procedure has been proposed to produce a quality ranking of selected metaheuristic algorithms, which are compared based on their optimization results, even if they were not originally tested with the same set of test functions, but only partially. The selected algorithms are evaluated using thirty-two test functions, which is a representative sample size. The evaluation also showed that while one algorithm produced the best overall results, this does not mean that this algorithm is the best for solving each function. This also highlights the need for further research in metaheuristic algorithms.

This paper presents a strategy for maximizing the effectiveness of high-speed spindle motors in manufacturing equipment. Using the ideal design of the stator winding geometry, as calculated by the Taguchi method, we were able to increase the maximum torque and efficiency. The rotor slot geometry was optimized using a response surface to raise the starting torque and reduce the starting current. The objectives of this investigation were to come up with a strategy for designing high-speed spindle motors so that they have better performance in terms of starting torque, maximum torque, efficiency, and starting current. Spindle motor temperature rise was the focus of the thermal measurements. Finally, a working spindle motor prototype was built and tested to verify the results of the Finite element analysis (FEA). The validity of the suggested model is demonstrated by a comparison between experimental measurements and finite element findings. The total percentage of mistakes was close to 2%.

Published: August 2023

This study examined the relationships among the dimensions of Unified Theory of Acceptance and Use of Technology (UTAUT) and external variables in the context of using artificial intelligence (AI)-powered tools for lecture design. After four months of utilizing the tools, 208 participants took the survey via Google Form. The structural equation model was utilized to analyze the obtained responses. Findings showed that performance expectancy, effort expectancy, social influence, and availability/accessibility are reliable predictors of users' intentions to utilize AI-powered design tools. However, the effects of facilitating conditions and trust and confidence are insignificant. The proposed conceptual model accounted for 54.6% of the data variation. This study provides designers and developers of AI-powered design tools with theoretical and practical implications that can enhance the practical adoption and utilization of these tools.
