Authors: Rudenko Elena , Andriienko Volodymyr
Published: November 2024

The object of research is the processes of managing the requirements of the marketing project using means of intelligent data analysis and artificial intelligence systems. Marketing projects include a large number of projects of various types, formats and scales. The work considers projects that are initiated at an existing pharmaceutical enterprise that produces drugs for the local market. Over a period of time, the company needs to introduce new dosage forms to the market. It is not about the development of new innovative drugs. Usually, these are new mixtures of known components, but according to the results of global research, adding new components to the formulation gives a new, additional effect. Also, it can be a new form, for example, a spray or syrup for children, etc. Nevertheless, in order to produce such a new product and bring it to the market, to make a profit, it is necessary to conduct a study of the local market in order to find analogues, consumer expectations and predict future cash flows from sales of new drugs. In order to form requirements for the project of creating and manufacturing a new medicinal form, the company initiates marketing projects. Such marketing projects are the subject of research.
As a result of the marketing project of the analysis of the drug market, it is necessary to form the contours of a new product and the requirements for the project of creating this product – a new medicinal product. Collecting and forming requirements is not a trivial task. Therefore, in the work, it is proposed to apply means of intelligent data analysis, which will be implemented on artificial intelligence systems. As a result, an intelligent model for managing the requirements of marketing projects of the pharmaceutical industry was developed. The non-triviality of the task of requirements formation is based on the fact that it is multi-criteria. The desired requirements and, accordingly, the future product of the project depend on: the lack of a similar dosage form on the local market, the presence of theoretical and practical pharmacological developments in this direction, the technical and financial capabilities of the enterprise, the expectations of stakeholders and consumers of the product. The use of intelligent tools will allow to avoid a conflict of requirements and to develop a medicine that will not only meet the expectations of all participants of the local pharmaceutical market, but also provide profit to the developing company.
Development of a regression model for effective labour management of an IT project
Authors: Borysov Oleksii
Published: November 2024

The object of the study is human resource management in IT projects, where the diversity of cultural characteristics and communication practices can affect the efficiency of task performance. The main problem addressed in this study is to identify the key factors that affect the effectiveness of human resource management in IT projects and to identify problem areas that need to be adjusted to improve the productivity and quality of teamwork. The study findings showed that the effectiveness of human resource management in IT projects largely depends on four main aggregate indicators: communication and interaction, cultural factors, leadership and management, and technical and professional skills. In particular, the model found that improved communication and interaction, as well as leadership and management, have the greatest positive impact on overall performance. Instead, cultural differences can create barriers that negatively affect teamwork performance. The findings are explained by the fact that effective communication and interaction are fundamental to coordinating teamwork, ensuring clarity of tasks, and timely information exchange. Leadership and management determine team motivation, conflict resolution strategies, and the overall direction of activities. The negative impact of cultural factors is explained by language barriers, differences in work approaches, and other cultural characteristics that can make it difficult to understand and cooperate. These findings can be used in practice in IT projects where multicultural teams work. They provide valuable guidance for leaders and managers on which aspects of management to focus on to improve team effectiveness. In particular, effective communication practices should be implemented, leadership skills and strategic planning should be developed, and cultural sensitivity should be taken into account, as well as training and development of technical and professional skills of team members. This will help overcome cultural barriers, improve collaboration, and increase the overall productivity of IT projects.

Monitoring of the inertization of cargo tanks of LNG class vessels
Authors: Matieiko Oleksii
Published: November 2024

The results of monitoring the inertization of cargo tanks of vessels intended for the transportation of liquefied natural gas are given. It is determined that the mandatory stage of cargo operations in the port of unloading of liquefied natural gas is the inertization of tanks. It is noted that on gas-carrying vessels, the following sources of inert gases can be: flue gases of vessel's auxiliary boilers; gases generated in the inert gas generator during the burning of liquid fuel in them; directly chemically pure inert gas (usually nitrogen). It is also stated that the inertization of cargo tanks is carried out by one of two methods: either dilution of the gas atmosphere (which is the process of mixing two environments), or replacement of the gas atmosphere (in which the gases supplied to the tank form a dividing layer and gradually displace the residual vapors cargo). The stability and integrity of the dividing layer determines the inertization quality of cargo tanks. Control of the state of the dividing layer in the cargo tank is impossible with optical or visual means of control, which is caused by the opaque environment inside the tank. In this regard, it is proposed to determine the integrity of the separating layer, as well as the level at which it is located in the cargo tank, by measuring the concentration of inert gas in the volume of the tank. Research was carried out on a gas carrier with a cargo capacity of 42,563 m3. Inertization of the vessel's cargo tanks was ensured with the help of nitrogen, which was generated by an inert gas generator using the Pressure Swing Adsorption technology. Nitrogen concentration monitoring in the volume of the cargo tank was performed at levels corresponding to 5 %, 20 %, 50 %, 80 % and 95 % of the tank depth. Research on determining the effect of nitrogen pressure entering the cargo tanks for their inertization on the stability and integrity of the dividing layer was carried out in the range of 0.95–1.05 MPa. The duration of the experiment was 210 minutes, fixation of nitrogen concentration values was performed every 30 minutes. As a result, optimal pressure values were established, according to which the inertization is ensured in the minimum time. The critical pressure values at which the separation layer breaks down were also determined.

Published: November 2024

The object of research is the tunable plasmonic properties of spherical and ellipsoidal silver nanoparticles in the organic semiconductor matrix. The average absorption cross-sections, scattering cross-sections, and optical radiation efficiency of spherical and ellipsoidal silver nanoparticles have been simulated. The long-wave statistical approach has been used to model the optical parameters of the assembled spherical and ellipsoidal nanoparticles. Statistical averaging is used here, where absorption and scattering are considered from an «effective» particle with statistical properties. This approach avoids complex calculations considering the details of the spectral characteristics of single nanoparticles of different shapes. Taking into account the fact that the nanocomposite matrix will contain ensembles of spherical nanoparticles of different sizes, the peak of their absorption and scattering cross sections will be shifted to the short wavelength region of the spectrum compared to ensembles of the same spherical nanoparticles. In addition, there is a slight increase in the absorption cross-section and a decrease in the scattering cross-section, confirming the presence of smaller nanoparticles. A study was made of a composite material containing a randomly dispersed ensemble of silver ellipsoidal nanoparticles of the same and different shapes and sizes in an organic semiconductor matrix. An ensemble of identical ellipsoidal nanoparticles is characterized by the presence of two plasmon peaks, which corresponds to the characteristics of a single ellipsoidal nanoparticle. A completely different situation is observed if to consider that the nanocomposite will contain an ensemble of ellipsoidal nanoparticles of different shapes and sizes. Such nanoparticles will be characterized by a plasmon peak for both the absorption and scattering cross-sections. This can be explained by the fact that as the size of ellipsoidal nanoparticles decreases, the distance between the peaks responsible for the longitudinal and transverse modes of plasmon excitation decreases. An increase in the shape distribution leads to a broadening of the absorption and scattering cross-section spectra. The efficiency of the optical radiation increases as the size distribution increases. It is shown that a change in the refractive index of an organic semiconductor matrix mainly affects only the value of the scattering cross-section of an ensemble of ellipsoidal nanoparticles dispersed in it. This research is a preliminary step to studying the influence of these particles on the properties of organic light-emitting structures.

The object of research is a functional apparatus for the production of paste-like and powdered vegetable semi-finished products. The problem of combined heat and mass exchange treatment of vegetable raw materials are solved by using a functional apparatus for concentration and drying for processing and production complexes, farm lands. The expected effect during the approbation of the device is predicted under the condition of a functional approach combining the processes of concentration and drying with precise control of the temperature regime due to the use of a film-like resistive electronic heater of the radiating type.
In the study, the approbation of a functional device for the production of multi-component vegetable semi-finished products of a high degree of readiness, with concentration and drying in the field of infrared heating at a temperature of 50 °C, was performed. Real-time temperature measurement was carried out by an automatic unit based on TRM, which ensured the accuracy of control at each stage. The temperature of the mashed mass during processing increased from 20.3 °С to 23.2 °С, reaching optimal conditions for forming a film with a thickness of 0.5 mm. In the rotary reboiler, the temperature in height varied from 25.7 °C to 50.1 °C, which contributed to the preservation of the properties of thermolabile raw materials. In the lower part of the apparatus, the temperature of the finished product was 49.8 °C, maintaining the necessary temperature regime for drying. The device creates a convective air flow (0.01 m/s) with the help of Peltier elements, which stabilizes the heat exchange at a temperature of 51.3 °C on the technical partition.
The practical use of the functional apparatus will allow its use at processing and production complexes and directly at the places of collection of plant raw materials for resource-efficient production of semi-finished products with a high degree of readiness. These semi-finished products can act as independent functional products for people in extreme conditions or as recipe ingredients for the recipes of various food products.

Published: November 2024

The object of study is digital branding. The process of attracting and keeping consumers in digital branding is considered. The phenomenon of digital branding and the basic tools of its impact on consumers are investigated. The global trends in the development of media consumption at the present stage are substantiated. Transformational changes in the process of consumption, as a consequence, have been proven to be transition to the area. It is determined that in order to attract and maintain online consumers, brands should respond quickly and establish effective feedback. Accordingly, the important role of digital branding is indicated. As a basis for the development of a marketing model of consumer involvement and keeping in digital branding it is proposed to use the AIDA model. The marketing model is indicated that allows to monitor the actions of consumers, as well as to control communication processes. The stages of the AIDA model in digital branding are highlighted – visiting the site, moving the goods to the basket, registration and payment of order. AIDA strategic tools in digital branding are identified. It is necessary to use the conversion coefficient to determine the efficiency of each stage of the model. It is proposed to supplement the classic Aida model with two elements of Satisfaction (S) and Loyalty (L) by receiving AIDASL. An advanced model of impact on consumers in digital branding has been developed. This model coordinates the stages of the AIDASL model with the main stages of the purchase decision process. The practical importance of the developed model of consumer involvement and maintenance in digital branding will increase the attention, interest, desire and level of purchase. This, in turn, will create the preconditions for increasing conversion at each stage of consumer contact with an online store, increasing their satisfaction and loyalty.

ABSTRACT Environmental conditions in hot and humid climates are highly unfavorable for grain storage, often leading to pest infestations that can cause irreversible damage to the stored product. This study evaluated the effects of compressor and blower rotations on the psychrometric properties of air in a cooling system designed for grain storage. Conducted in Dourados, Mato Grosso do Sul, Brazil, the experiment utilized an Autonomous System for Cooling and Psychrometric Control of Grain Storage Conditions (SIARCONPAG), which adjusts exit air conditions to maintain the hygroscopic balance of grains in tropical environments. Tests were performed in three different operating modes, varying the temperature and relative humidity of the inlet air. Results showed that compressor and blower rotations significantly affected the temperature and relative humidity of the output air. The system, tested under controlled conditions, reduced the average storage temperature by up to 5 °C and maintained relative humidity between 60-65%, which is ideal for grain preservation. The system’s energy consumption was optimized, achieving 20% greater efficiency compared to traditional cooling systems. SIARCONPAG effectively manipulated psychrometric air conditions, with the isothermal humidifier and secondary condenser adapting to both low and high humidity levels. The results suggest that the system provides an efficient solution for controlling grain storage conditions in tropical regions, reducing post-harvest losses and contributing to food security. This study advances the development of grain storage technologies and supports more sustainable agricultural practices.

ABSTRACT Endophytic microorganisms in lettuce plants have received little attention for their potential biological control of phytopathogens. This study aimed to isolate, identify, and select endophytic bacteria from lettuce seedlings cv. Brava and Creta, antagonistic to the phytopathogenic fungus Alternaria sp. (ALT23) in culture media through direct interaction. The experimental design was completely randomized in an 11 x 2 factorial scheme, with 11 treatments [Control - ALT23 and 10 previously selected bacterial isolates] and two evaluation periods (the 5th and 8th day after inoculation) with four replications each. The 16S rDNA gene sequences of the isolates revealed a high similarity with Bacillus tequilensis KCTC 13622, B. subtilis NCIB 3610, B. velezenzis CR-502, B. siamensis KCTC 13613, and Paenibacillus polymyxa ATCC 842. The selected bacterial isolates reduced ALT23 mycelial diameter (46.2-65.3%) and rate (51.8-91.6%). We conclude that endophytic bacterial isolates with antagonistic potential against phytopathogens must be selected after more than five days of cultivation in a culture medium, as longer cultivation times favor endophyte inhibitory activity.

ABSTRACT Biochar is formed by the thermal treatment of biomass in a low-oxygen atmosphere through pyrolysis or carbonization. It is used as a soil conditioner since it reduces acidity and the availability of Al while increasing the pH and the availability of nutrients, especially phosphorus (P) and potassium (K), to plants. In this study, we evaluated P adsorption by clay soils incubated with different doses of biochar made from poultry litter, coconut fiber, and rice straw produced in a drum-type oven. For this, an experiment was conducted at the Irrigation and Salinity Laboratory (ISL) of the Agricultural Engineering Department of the Federal University of Campina Grande, PB, using soil samples collected in the state of Paraíba. Different doses of biochar were added to the soil samples and incubated for 160 days, keeping their humidity at about 70% of field capacity, with the addition of deionized water. These samples were subsequently used in the phosphorus adsorption study. The pH and phosphorus content of the soil after incubation with the different biochars were determined, the parameters of the Langmuir and Freundlich P adsorption isotherms were assessed, and Fourier-transform infrared spectroscopy (FTIR) and X-ray diffractometry (XRD) were performed. Based on the experimental conditions, poultry litter biochar was found to be effective because of its high adsorption capacity, considering that 9 t ha-1 of this biochar could adsorb about 0.223 mg g-1 phosphorus under appropriate conditions.
Erudição e amadorismo: notas sobre o ensaio e o poema-ensaio em Anne Carson
Authors: Fernandes Rafael Zacca
Published: November 2024

Resumo O artigo procura caracterizar a prática do ensaio e do poema-ensaio em Anne Carson a partir de uma investigação: de seus escritos e entrevistas sobre o tema; da forma de seus poemas-ensaios, em especial o “Ensaio sobre aquilo em que mais penso”; e da teoria do ensaio em autores como Montaigne, Theodor Adorno e Timothy Corrigan. Para tanto, o artigo mobiliza as categorias de erro, dúvida, amadorismo e prazer e se pergunta sobre a sua relação com a noção de especialidade, contra a qual a noção de ensaio emerge na contemporaneidade.
Ensaiar a incerteza: “a ideia de poesia” como questão para a prosa
Authors: Lopes Guilherme de Souza
Published: November 2024

Resumo Partindo do debate crítico a respeito de uma “ideia de prosa” como horizonte para a poesia contemporânea, em que está implicada certa compreensão histórica da prosa relacionada à atualidade e à consequência política, proponho, por meio de leituras localizadas das obras heterogêneas de Jorge Luís Borges, Michel de Montaigne e Machado de Assis, uma determinada herança narrativa que possa inverter os vetores tradicionais do problema. Ainda que distante de experimentações hibridizantes com o poético, a prosa descrita constitui-se em direção a uma “ideia de poesia” e, por meio de elaborações sobre o mistério, o sublime e a experiência do sensível, elabora outros modos para experienciar a responsabilidade do literário. A hipótese é a de que o gênero ensaio, sobretudo a partir do aproveitamento das consequências da obra de Montaigne, configura-se como herança possível para que a prosa ensaie formulações sobre o literário em sintonia com o pensamento poético.

Para tal, o artigo se vale de uma interpretação minuciosa de seu poema “Homenagem a Gödel”.
O método Carson
Authors: Calcagno Victor
Published: November 2024

Resumo Pela análise de “Cassandra Float Can”, este artigo investiga como a escrita de Anne Carson está ligada a aspectos historicamente desenvolvidos pela teoria do ensaio. Entre a constelação de referências e a aproximação comedida, o ensaísmo foi conceituado via ensaios que apontavam originalidade na mescla de conteúdos. No texto discutido, no entanto, Carson cerca seu tema também por um uso recombinado de diferentes formas, como a poesia e a tradução. Esses usos estão em diálogo franco com o argumento principal da autora no trabalho, de que traduzir é alterar, ou cortar, superfícies.

Resumo O artigo relê o ensaio O pensamento do tremor (2014), de Edouard Glissant, e discute como a proposta de pensar no tremor (e não sobre o tremor) se aproxima das incertezas contemporâneas. Incertezas que serão abordadas aqui numa dupla vertente: nas suas relações com a forma-ensaio (e logo com um certo desvio dos pensamentos sistêmicos), e na hipótese subjacente a todo o texto, de que as incertezas se agudizam porque atravessamos um momento de mudança da própria episteme moderna ocidental.

Published: November 2024

Resumen Sobre la base de la Retórica General Textual de Stefano Arduini (que asimila el legado teórico de Antonio García Berrio) y del pensamiento de Antonio Cornejo Polar (quien representa la sociocrítica en la investigación literaria peruana), el autor analiza El huso de la palabra, poemario fundamental de José Watanabe Varas, uno de los grandes poetas peruanos de los años setenta del siglo pasado. Se cuestiona la retórica restringida a la elocutio y se precisan los conceptos de campo figurativo (formulado por Arduini) y el de sujeto migrante (planteado por Cornejo Polar). Luego, el autor examina dos poemas de Watanabe, cuestionando el contextualismo que deja de lado el abordaje textual para rendir culto ciego al contexto.

Published: November 2024

Objective: to unveil the experiences of transsexual men during childbirth and postpartum in the light of the Theory of Diversity and Universality of Cultural Care. Method: a qualitative and descriptive study using the multiple case study method. Data was collected using an intentional sample of five transsexual men, selected on the basis of convenience and availability. The interviews were transcribed in full and the results were organized and adapted to the Sunrise Model. Results: the majority of the participants were «primiparous» and had given birth by cesarean section. In adapting the Sunrise Model, we observed the encouragement of medicalization and mechanistic management of childbirth; fear of natural childbirth; violence perpetrated against transsexual men resulting from the difficulty of access to information by the pregnant man, and obstetric care not qualified to meet the needs of the public, resulting in fragile care, with dissatisfaction with the health service. Conclusion: the experiences of transsexual men during childbirth and the postpartum period are a mixture of experiences that generate damage, especially when linked to situations of transphobic violence and violation of rights

Objective: to develop and validate two clinical simulation guides to support and disseminate a culture of safety in the surgical environment. Method: methodological study supported by the International Nursing Association for Clinical Simulation and Learning theoretical framework. The snowball technique was used to validate the clinical guidelines with experts on the subject. Two scales validated for Brazil were used for the pilot test. Results: 89 operating room professionals took part, including 41 doctors, 40 nursing technicians, four nurses, two radiology technicians, and two nursing trainees. Two guides were created, one on conflict management and teamwork in patient safety during the transfer of the patient from the operating room to the post-anesthetic recovery room, and the other dealing with the assistance of the healthcare team in the transfer of care in the post-anesthetic recovery room. The evaluation of Satisfaction with Simulated Clinical Experiences had an average score of 8.3 and Satisfaction and Self-confidence in learning 4.1. Conclusion: the guides have been validated and are suitable for replication in any surgical environment. We believe that this technology could contribute to improving the safety culture in the operating room by providing an opportunity for reflection and critical thinking.

Objetivo caracterizar el patrón de uso de smartphones y tablets en una muestra de niños de hasta 5 años y evaluar con qué variables se asocia. Método estudio transversal con 410 padres de niños de hasta 5 años de edad. Los datos se obtuvieron a través de un cuestionario online . Se realizaron preguntas sobre el tiempo y patrón de uso diario de smartphones y tablets . Se calculó el porcentaje global (y el intervalo de confianza del 95%) y la mediana (y rango intercuartílico) de tiempo de uso de cada dispositivo, según las variables asociadas al niño y a las características del entrevistado. Resultados se estima que el 44,7% (IC 95%: 37; 51) de los niños utilizaban diariamente smartphones y/o tablets . El tiempo medio de uso de smartphones y tablets por separado fue de 30 minutos por día para los smartphones (8,6-38,6) y de 30 (17,1-60,0) para las tablets . El 11,6% (IC 95%: 6; 16) de los niños que tienen acceso libre a dispositivos los utiliza dentro de los 30 minutos después de haberse despertado durante la semana, el 15,4% (IC 95%: 10; 21) durante los fines de semana y el 14,0% (IC 95%: 8; 19) utiliza smartphone y/o tablet hasta 1 hora antes de dormir. Conclusión más de 4 de cada 10 niños de nuestra muestra utilizan smartphones y/o tablets diariamente. La enfermería comunitaria puede ser una opción para implementar programas educativos orientados a promover prácticas saludables sobre el uso de dispositivos electrónicos por parte de los niños, debido al patrón de uso excesivo de pantallas en la población pediátrica.

Objective: to assess the job satisfaction level, stressors and working conditions of nursing professionals in some Latin American countries during the COVID-19 pandemic. Methods: this is a cross-sectional study of nursing professionals working in hospital, primary care, educational, governmental, research, commercial and independent institutions. An online survey was carried out to assess satisfaction with the Font-Roja instrument, sociodemographic characteristics, stress factors and working conditions. Results: a total of 1,215 workers from Argentina, Colombia, Mexico, Ecuador and Panama participated. The overall satisfaction score was 81.5 (SD:11.6). There was less satisfaction in the dimensions of tension, pressure, extrinsic characteristics and monotony. Increased stress at work (84.3%), workload (81.3%), fear of SARS-CoV-2 (67.7%), uncertainty at work (51.2%) and salary reduction (20.4%) were reported. The work factors related to satisfaction were, as follows: job recommendation, mixed working hours, care work, increased stress, increased workload, salary reduction and purchase of protective equipment. Conclusion: the aspects of job satisfaction most affected during the pandemic were pressure, tension, lack of independence and monotony at work; this satisfaction was reduced due to increased stress and workload, the acquisition of personal protective equipment and a reduction in salary.

Objetivo: mapear las características y las finalidades de las tecnologías de Realidad Virtual (RV) para adultos mayores en la comunidad. Método: revisión de escopo, según la recomendaciones del JBI ( Joanna Briggs Institute ) y descrito de acuerdo con el Preferred Reporting Items for Systematic Reviewas and Meta-Analyses Extension for Scoping Reviews . Fueron incluidas diez bases de datos y cuatro plataformas referentes a la literatura gris. La selección de los estudios fue realizada después de la remoción de duplicados, evaluación individual y también en pares. El análisis de similitud fue utilizado para identificar las afinidades entre las palabras y sus resultados. Resultados: fueron mapeados 20 estudios de RV para los adultos mayores, siendo la mayoría del uso de dispositivos no inmersivos. Las principales finalidades del uso de la RV con adultos mayores fueron mejorar y/o rehabilitar las funciones que entran en declino con el envejecimiento, de forma fisiológica o provenientes de enfermedades o daños. Los dispositivos de RV constituyen una potencial herramienta para la prevención de caídas y disminución cognitiva, y favorecen la ejecución de actividades instrumentales de la vida diaria. El análisis de similitud resultó en la generación del árbol máximo, que permitió identificar la interrelación con los términos “realidad virtual” y “adulto mayor”, como elemento central e intermediario, respectivamente. Conclusión: se recomienda el desarrollo de nuevos estudios, en otros ambientes, para permitir una mayor amplitud en el uso de la RV, por profesionales de la salud, en especial de los enfermeros, en la asistencia prestada a los adultos mayores.
