Estimation des pertes d’énergie à l’entrée des onduleurs d’une installation photovoltaïque raccordée au réseau
Authors: Dias Joao Batista , Krenzinger Arno
Published: February 2024

Ce travail présente une estimation des pertes d’énergie à l’entrée des onduleurs lorsque l’éclairement est très fort, aux environs de midi. Les onduleurs font partie d'une installation photovoltaïque raccordée au réseau électrique, laquelle utilise des modules au silicium monocristallin de 100 Wc et onduleurs de 1100 W à la sortie. Cette installation a été divisée en trois sous-systèmes où chacun d’eux a une puissance différente, ce qui a permis de faire des analyses entre eux. Des corrélations ont été rencontrées en effectuant une série de mesures électriques sur une année. Les résultats obtenus ont montré que les pertes énergétiques sont plus élevées à midi dans deux sous-systèmes seulement, suivant les puissances installées. Le troisième sous-système n’en a pas présenté, même à midi. Il est donc important de savoir que les corrélations qui sont présentées ici s’appliquent à des cas spécifiques ou dans d’autre installation similaire à celle-ci. De toute façon, la méthodologie utilisée ci-après peut être modifiée en fonction du lieu d’implantation, la puissance du champ de modules et des onduleurs, pour aider à d’autres dimensionnements de systèmes photovoltaïques raccordés au réseau.
Etude expérimentale d’un chauffe-eau solaire à stockage intégré dans des conditions réelles
Authors: Chaouachi Béchir , Gabsi Slimane
Published: February 2024

Le présent travail représente une étude expérimentale d’un chauffe eau solaire à stockage intégré, d’une nouvelle et simple conception, dans un climat tunisien. Ce chauffe eau est équipé d’un système de concentration comportant trois branches paraboliques favorisant une meilleure absorption du rayonnement solaire. Grâce à la libre rotation du système de concentration, on peut minimiser les pertes au moyen d’un dispositif de commande permettant de renverser le système pendant les périodes non ensoleillée. Les résultats expérimentaux ont montré des performances thermiques acceptables malgré la simplicité du capteur. Enfin, une amélioration peut être facilement apportée que ce soit par le perfectionnement de l’isolation thermique ou l’utilisation des surfaces sélectives de captation.

Analyse technico économique d’un système hybride (photovoltaïque/éolien) autonome pour le site d’Adrar
Authors: Diaf Said , Haddadi Mourad , Belhamel Maiouf
Published: February 2024

Nous présentons dans cet article une étude de dimensionnement et d’optimisation technico-économique d’un système hybride photovoltaïque/éolien autonome avec batteries de stockage. Deux méthodes sont développées pour ce type de système. La première est basée sur la moyenne des valeurs mensuelles annuelles dans laquelle la taille des générateurs photovoltaïque et éolien est déterminée à partir des valeurs moyennes mensuelles des contributions de chaque composant. Dans la seconde méthode, la détermination des tailles de ces deux composants du système est basée sur le mois le plus défavorable (défini comme étant le mois qui nécessite la plus grande utilisation de la surface du générateur photovoltaïque/éolien). L’optimisation a été effectuée en tenant compte du paramètre économique qui représente un critère à ne pas négliger dans les systèmes fonctionnant avec des sources renouvelables. Afin de faire ressortir la configuration technico-économique optimale, plusieurs combinaisons de la fraction de la charge alimentée par le photovoltaïque sont considérées et pour lesquelles le coût total est déterminé. La configuration optimale sera ainsi obtenue pour les deux méthodes. Nos résultats montrent que le photovoltaïque présente une variante plus favorable dans le site d’Adrar relativement à l’éolien et cela par les deux méthodes utilisées. La méthode du mois le plus défavorable présente un coût du système plus élevé par rapport à celle de la moyenne des valeurs mensuelles par an. Cela est du à la meilleure fiabilité que présente le système déduit de cette méthode.

Published: February 2024

Le choix d’un système énergétique doit obéir et respecter certaines règles. Le système énergétique choisi doit démontrer au préalable sa compétitivité vis-à-vis d’autres systèmes pour le même service rendu. Sa crédibilité doit reposer sur des bases économiques et techniques. Le présent article se propose l’analyse par une méthode numérique, de la rentabilité économique d’une installation de pompage photovoltaïque, laquelle est comparée à une autre installation de caractéristiques identiques mais fonctionnant par groupe électrogène. La méthode proposée est basé sur la détermination du coût global actualisé du mètre cube (m3) d’eau pompée en fonction des besoins exprimés (volume d’eau puisé quotidiennement), des caractéristiques de la source d’eau et du site d’implantation (hauteur manométrique totale, débit maximal, ensoleillement,.). De cette analyse, découlera le choix sur l’investissement à effectuer, car l’analyse des coûts et de la rentabilité est un préalable incontournable avant toute décision d’investissement sur des équipements énergétiques que ce soit en énergie solaire ou en une autre énergie conventionnelle (diesel ou autres). L’opportunité de ce travail est double. Il permet d’avoir une idée précise sur les coûts d’investissement en connaissant les besoins de l’usager et le site d’implantation d’une part, et d’autre part optimiser l’installation photovoltaïque en fonction des divers éléments.

Authors: Antari Jilali , Iqdour Radouane , Zeroual Abdelouhab
Published: February 2024

This investigation has two main objectives. The first one is to propose a statistical method, based on the fourth order cumulants, to identify single-input single-output ‘SISO’, finite impulse response ‘FIR’ system using non gaussian input, zero mean and independent identically distributed signals. The second objective is to search, as an application, a model for forecasting the wind speed time series and to compare the obtained results with those obtained using the Takagi- Sugeno ‘TS’ fuzzy techniques. The prediction results obtained by the proposed method show that the sequences of generated values have the same statistical characteristics as those really observed and better than those obtained using ‘TS’ fuzzy systems. Additionally, the model developed on the basis of the statistical method fits well wind speed time series and can be used for forecasting purpose with an accuracy of 94 % and above.
Development of a voltage regulator for solar photovoltaic cathodic protection system
Authors: Kharzi Souhila , Haddadi Mourad , Malek Ali
Published: February 2024

The voltage regulator is one of the main elements from which depends the reliability and the efficiency of the photovoltaic system. Among the large number photovoltaic applications, we are interested by the cathodic protection, it’s recognized as one of the most efficacious means of the active prevention against the corrosion. Photovoltaic cathodic protection is one of the possible solutions for the structures subjected to corrosion, mainly in oil and gas industries [Tanasescu et al., 1988]. In this paper, the study about the design of a voltage regulator with variable output for solar photovoltaic cathodic protection has been carried out. Our system is based on two microcontroller controlled DC/DC converters: the first one is a buck used to match the maximum power point voltage of the solar panel to the battery charging voltage; and the second one is a buck-boost used between the batteries and the load in order to adapt the regulator at any cases of the cathodic protection stations. Usually, cathodic protection systems are working with constant current output which is the necessary condition to procure immunity voltage of the structures that strictly required preventing corrosion from occurring. The major difficulty to achieve this goal is the variations of the surrounding medium resistivity to overcome this difficulty, we propose an automatically adjustment of the output voltage of the buck-boost converter to feed the load (sacrificial anode-protected structure) thanks to the microcontroller by generating the required duty cycle by way of its PWM output. The developed system allows the solar panel to operate at its maximum power point output (MPP), when the MPP changes, the microcontroller changes the conversion ratio (duty cycle) of the buck circuit to keep the solar panel at its MPP. The buck steps higher voltage panel down to the battery charging voltage. In this paper, the study about the design of this voltage regulator with variable output for solar photovoltaic cathodic protection has been described.
Impact des différents facteurs physiques et du rayonnement solaire sur la diversité malacologique dans la région de Tlemcen (Algérie)
Authors: Damerdji Amina , Benyoucef Boumediene
Published: February 2024

La région de Tlemcen est située dans le Nord-Ouest algérien. Elle se caractérise par un climat méditerranéen. L’inventaire de la malacofaune a été réalisé. Les échantillonnages effectués dans différentes stations de la région de Tlemcen ont montré la présence de 68 espèces. Elles sont réparties en deux espèces de Milacidae, cinq espèces de Sphincterochilidae, une seule espèce de Subulinidae avec Rumina decollata et une seule espèce de Ferussaciidae. Toutes les espèces restantes forment la famille des Helicidae. Les principaux facteurs physiques (état hygrométrique, température et lumière) agissent sur la diversité malacologique. De même, le rayonnement solaire influe de façon non négligeable sur la densité et la couleur des espèces testacées. Des phénomènes d’adaptation (estivation et formation de l’épiphragme) traduisent les variations de ces facteurs environnementaux.

Published: February 2024

Dans ce travail, nous avons élaboré une confrontation entre des valeurs mesurées sur deux sites algériens et des valeurs estimées par des modèles théoriques proposés dans la littérature par divers scientifiques et qui ont prouvé leur validité sur plusieurs sites dans le monde. Il s’agit d’une part des sites de Bouzaréah et de Ghardaïa comme sites sur lesquels on collecte continuellement des données météorologiques et radiométriques. D’autre part, parmi les modèles de reconstitution retenus, nous citons le modèle de Sasamori et al., le modèle de Bird and Hulstrom, le modèle de G.W. Padridge et al., et celui de Ashrae. Nous avons alors constaté que pour certains, il existe une bonne concordance entre les valeurs mesurées et celles estimées par certains modèles pour le site de Bouzaréah, alors qu’ils ne le sont pas avec les valeurs mesurées pour le site de Ghardaïa. L’inverse a été observé pour d’autres modèles. Alors que parmi ces modèles, pour les valeurs calculées par d’autres modèles, ils sont en bonne concordance avec les valeurs mesurées sur les deux sites considérés.

Authors: Journal IJSREM
Published: February 2024

The process of creating music involves various techniques, including beat detection and classification. This research paper proposes a novel approach to detecting and classifying beats in music production using a recurrent neural network with long short-term memory (RNN-LSTM) algorithm. The proposed method uses a set of features that are extracted from the audio signal, including spectral flux, zero- crossing rate, and energy, to train the RNN-LSTM model. The model is trained using a large dataset of music tracks and is capable of predicting the beats and their respective classifications accurately. The proposed approach was evaluated on a dataset of various music genres, and the results showed that the RNN-LSTM algorithm outperforms traditional beat detection and classification techniques. The algorithm achieved an high accuracy as compared to the traditional techniques. Additionally, the proposed method is capable of detecting and classifying beats in real-time, making it useful formusic production applications. The proposed approach has several potential applications, including music production, DJing, and music analysis. It can be used to identify the beats ina song, which can be used to synchronize different tracks, createremixes, and enhance the overall listening experience. Furthermore, the proposed method can be used to analyze the characteristics of different music genres and identify the underlying patterns that define them. Keywords— Beat Detection, Beat Classification, Music Production, RNN-LSTM algorithm, Music Analysis.

Weaving Modernity in Salafism
Authors: Nasir Muhammad Muhammad
Published: February 2024

This study examines the parallels between Muhammadiyah, the oldest and largest modernist Islamic movement in Indonesia, and Jama’atu Izalatil Bid’a Wa Ikamatus Sunnah, also known as Izala, the most significant Islamic reformist movement in West Africa, which originated in northern Nigeria. Concurrently, these groups share a common focus on socio-religious reform and a commitment to puritan Islam. It is undeniable that various Islamic movements/groups have existed and continue to exist outside the Arab world, but relatively few studies have focused on Islamic groups operating in West Africa or Southeast Asia, for example. This study highlights the importance of examining Islamic movements in regions beyond the Arab world, particularly in West Africa and Southeast Asia. The large Muslim populations in Indonesia and Nigeria offer a rich context for exploring the dynamics of Islamic movements. The research reveals, despite the groups’ Salafi-inspired ideologies, they mediate socio-religious reform, indicating the modernising rather than conservative aspects of Indonesian and Nigerian Islam. Within their respective contexts, these groups represent forms of reconstructed alternative modernity, or distinctly Islamic interpretations of modernity, which they define through executing their reform activities within Islamic frameworks. They navigate the complexities of modernity by balancing adherence to traditional values with adaptation to contemporary developments. Notably, the study is driven by a belief that comparative studies across different Salafi-inspired groups in distinct contexts could provide broader understanding of the evolving relationship between Salafism and modernity.

Published: February 2024

The project deals with the insertion of Intellectual Property (IP) as a transversal and interdisciplinary strategy in the integrated high school courses of the Federal Institute of Education, Science and Technology of Pará (IFPA) Campus Belém. We understand that socioeconomic development permeates IP, in direct proportion to technological innovation becoming more and more present, with the process of education and dissemination of IP as a generating problem, and as a dispersing core of research for formative convergence on the Campus of IFPA Belém , anchored in the Education and Dissemination constructs. We chose to develop the Action-Research methodology, taking into account the strategic actions proposed with the target audience. We hope to present results on the efficiency of convergence, based on a growing number of technological products developed and disseminated. Make an educational product viable at the end of the process, tending to IP as a didactic strategy. This project aims to make it possible to understand two different aspects and fields of protection of IP, in addition to highlighting the role of integration between IP and Professional and Technological Education (EPT) in the integral development of the being and its relations with the economy. Ultimately, this development, which originates locally, expands and occupies a prominent place on the global stage as technological innovation becomes the focus of competitiveness. It is expected that, by incorporating IP and the development of its competencies in the teaching-learning curriculum, students and teachers can instigate, in addition to an interest in science, inventiveness or planning, a vision of the market or entrepreneurship, resilience, attitudes and values .

An artist in public square
Authors: Konrath Germana , Reyes Paulo Edison Belo
Published: February 2024

At the intersection between the City, the Urban and the Human, between artistic and scientific knowledge, this text is placed, proposing the superposition of distinct forces acting on a given public space. The most emblematic place is the Plaza de la Constitución (or el Zócalo, as it is popularly known): the largest and oldest square in the center of Mexico City. This urban space gains new layers and dynamics through the poetic actions of the Belgian-Mexican artist, Francis Alÿs, who develops part of his work there. The article presents four of these actions, carried out between 1994 and 1999, and discusses its capacity for tensioning the temporalities at stake in the created situations and for provoking critical and political thinking about the sociabilities and urban identities that agitate there. Alÿs's set of artistic interventions will be debated through Lefebvre's theoretical legacy and the notion of the right to the city; de Rancière's and the relationship between aesthetics and politics; de Deleuze and Guattari's regarding agenciamentos e territorializations. The authors will help to structure an analysis matrix and thus launch possible readings about the contributions of the artist and his actions to the public space, working from the contemporary to talk about the many times that make up the now.

Natural gas consists mainly of methane (CH4) and other lighter hydrocarbons, but it has traces of contaminants such as carbon dioxide (CO2) and hydrogen sulfide (H2S). These gases should be eliminated or reduced to the minimum concentration percentage because they are toxic, corrosive and harmful in high concentrations, as well as to avoid obstruction of pipelines of a pipeline and to meet market specifications. The most commonly used procedure to remove CO2 and H2S from natural gas is the chemical absorption process (sweetening and/or desulphurization), using alkanolamines as solvents, and the amine most commonly used in Brazil is diethanolamine (DEA). In this study, the sweetening process was conducted at the ASPEN PLUS® Chemical Process Simulator. The simulations took place on a permanent basis, using the method of stages in equilibrium and the DEA as solvent. Parameters such as amine current inlet temperature, DEA concentration, number of stages in the absorber, and DEA current pressure were evaluated. In addition, sensitivity analyzes were conducted using the Amines, ELECTNRTL and Peng-Robinson (PR) Thermodynamic Models. As results, it was observed that the Amines model was the one that best represented the stage of sweetening natural gas (separately and in recycled form), obtaining a purer gas, with smaller fractions of CO2 and H2S.
Influence of nutrition on gestational diabetes in Brazil
Authors: De Freitas Allana Thaís Mendonça Mota
Published: February 2024

Nutritional screening can be preventive or therapeutic, helping to prevent and treat diseases related to eating habits or genetic conditions. In the context of gestational diabetes (DG), dietitian follow-up is essential to prevent insulin resistance from progressing to type 2 diabetes. The article also promotes the importance and risk that accompanies the presence or absence of the appropriate BMI, thus bringing a brief quote from Pedrini, we can assess in a concrete way the risk that accompanies your pregnancy if there is absence of more balanced eating habits. With this, the later development concludes the best approaches that should remain during and after pregnancy, exposing data and new sources so that everyone absorbs what is being exposed in the article. The following bibliographic review aims to discuss the importance of nutritional monitoring during pregnancy, especially in cases of DG. The article's methodology is based on a narrative bibliographic discussion, based on prospecting and selection of articles from 2016 to the present date. The research was carried out in a narrative-descriptive manner, with a qualitative analysis of the proposed theme. The theoretical basis of the work includes several sources, such as the Brazilian Ministry of Health, Mendes (2019), Government of the State of Bahia (2017), Lucena et al. (2021), among others. The promotion described is linked to the importance of nutritional therapy and its necessity during pregnancy for the treatment of gestational diabetes. The text presents two subsections of bibliographic review: one on the action of the nutritionist in prevention and nutritional therapy, and another on the action of the nutritionist in cases of DG in Brazil. The research in question allowed for a contemplation that the main influence of nutrition in the face of gestational diabetes in Brazil says about nutritional therapy as an important tool to prevent the DG from evolving to a diabetes mellitus in the woman during or after pregnancy.

There are numerous challenges for teaching institutions that seek in their teaching plan, the increment of initiatives that aim to potentiate the school, teachers and students indexes, through technological means, or that use this resource as an aid for that. However, the scenario in real life that we end up encountering is completely the opposite of the one we plan or idealize for our work and for the perpetuation of our students' learning, institutions that are totally helpless and alien to any resource or capacity to house a technological equipment that allows such application in the pedagogical practice and in the transmission of learning and knowledge. This obviously brings countless benefits to the students, provided that such methodology is taken from good studies and a good action plan which highlights the positive and negative points, also points out what would be the advantages and disadvantages for the institution and the risks of failures that this may bring, outline alternative plans that circumvent the possible weathering that may threaten this teaching model. In this way, this work aims, from its beginning, at the elaboration of a construction on the theme Screenagers and Education, and how the use of technologies and the ease of application of it in the classroom, as the younger ones from the 80's have a ease of handling technological tasks and also reflecting on premature immersion in contact with technologies can favor or limit an individual.

The idea that knowledge should be built through interaction between people is not current, since the 18th century, educators already used the philosophy of meaningful learning, seeking to develop autonomy in students to enhance their learning and consequently the development of their profession. In recent decades, the collaborative learning proposal has been gaining supporters at all levels and modalities of teaching and learning, due to the fact that learning collaboratively makes learning more efficient and meaningful. With the use of technological resources, the collaborative learning proposal is reinforced, as this association can enable dynamic learning with different results for specific contexts. The means of attending to and obtaining the learning process requires instruments that help in the pedagogical planning, in the definition of objectives, in the choice of resources, among them, the technological ones and in the evaluation instruments. The adoption of the paths described and suggested by this methodology is one of those instruments that aims to support these choices, with a view to making collaborative learning efficient and successful, establishing a relationship between cognitive development and learning objectives. Thus, in this work, the importance of collaborative learning for learning focused on student autonomy will be highlighted. In addition to imposing the possible adoption of the Blended Learning modality to reinforce the connection and exchange of information in collaborative learning and Bloom.
Pay disparities in the Federal District Civil Police and the impacts of Law 9264/96
Authors: Gomes Claudia Alessandra , Marinho Paulo Sergio Ramirez Penna
Published: February 2024

This article investigates the historical origin of salary disparities in the Civil Police of the Federal District (DF), with an emphasis on the implications of Law 9264/96, which established the requirement for higher education for entry into certain positions. The research employs an exploratory documentary analysis of relevant legislation and administrative records to trace the evolution of salary policies and identify points of failure in their implementation. It was observed that, despite subsequent legislative changes aimed at defining higher-level functions, an ineffective implementation resulted in salary inequalities among similar positions. This salary discrepancy originated from an administrative error in the application of Law 9264/96, maintaining the subsidies for some positions based on the mid-level salary table of Decree Law 2266/85. The article offers a critical analysis of salary policies and their consequences on the structure of the Civil Police of the DF, aiming to document the evolution of this salary difference. The conclusions indicate that such disparity not only contradicts the principles of equity and salary justice but also reflects challenges in administrative adaptation to new legal standards. The study underlines the need for periodic and effective reviews in remuneration structures to align administrative practices with legal requirements and workforce needs. The aim is to provide a historical record that clarifies the reasons for salary disparity, contributing to a deeper understanding of the complexities associated with remuneration in the same career, and suggesting paths for future reforms in human resources management in the Civil Police of the DF.

Published: February 2024

Know the meaning of territory from the perspective of primary care nurses. An exploratory-descriptive study with a qualitative approach was conducted in ten primary healthcare units located in the city of Boa Vista, Roraima, Brazil. The social group consisted of eight permanent municipal employees who are nurses. Data collection took place from December 2022 to February 2023 through semi-structured interviews. The audio recordings amounted to approximately one hour and twenty minutes, which were transcribed manually and analyzed according to Bardin's theoretical framework. The meanings related to territory from the perspective of nurses working in primary care were organized into three thematic categories, namely: territory understood as the area of coverage for professional healthcare services, territory seen as a meeting place for healthcare professionals with priority groups, and territory interpreted as a space for care management. The meanings regarding territory have been decoded as the geographical space for the activities of the primary healthcare team professionals. Territory as the care location for priority groups, with emphasis on children, pregnant women, elderly individuals diagnosed with hypertension and diabetes, bedridden patients, migrants, individuals with disabilities, disadvantaged and vulnerable groups. Finally, (re)recognized as the place where action planning, organization of healthcare practices, service coordination, primary team supervision, and care evaluation take place.

The experimental design was completely randomized with hybrids and 4 replications (lot 1 – Hyola 571 CL; lot 2 – Hyola 433; lot 3 – Hyola 76; lot 4 – Hyola 401; lot 5 – Hyola 61 and lot 6 – Hyola 50). Physical quality (degree of moisture and weight of a thousand seeds) and physiological quality (germination, first germination count, germination speed index, seedling emergence, emergence speed index, root length, shoot length and total, seedling dry mass). For the electrical conductivity test, variations in water volume (25, 50, 75 ml), number of seeds (25, 50, 75 and 100 seeds) and exposure time (1, 3, 6, 9.12 and 24 hours). Four replicates of each lot were evaluated. The electrical conductivity test was efficient for evaluating the physiological potential of canola seeds, with combinations of 50 or 75 seeds immersed in 75 ml of deionized water, for periods of 6 and 9 hours, providing better stratification of lots.

The integration of risk management into quality management, a major challenge for public laboratories, will bring even more reliability to the results issued, enhancing opportunities and minimizing risks to public health. The proposed systematics was applied as a case study to the trial to determine the potency of the hepatitis B vaccine, carried out at INCQS, which has ABNT NBR ISO/IEC 17025 as the basis of its quality management system and follows follows the Management guidelines of the Federal Accounting Court (TCU) and Office of the Federal Controller General (CGU), the Fiocruz Risk Management Guide and ABNT NBR ISO 31000. The main result was the elaboration of a work process with a description of steps and techniques, which allow risk management to be integrated with quality management, adding benefits to ensure the reliability of analytical results bringing benefits to the citizens.
Grief processes in the COVID-19 pandemic: narrative review
Authors: Correa Mariele Rodrigues
Published: February 2024

In March 2020, the World Health Organization (WHO) declared a global pandemic for Covid-19, a disease caused by the new coronavirus. Several sanitary measures had to be adopted to prevent the contagion and spread of the virus, in addition to countless changes and adaptations in daily life, which generated several symbolic losses and also loss of human life, especially in Brazil. Thus, the present study seeks to analyze scientific production on the issue relating to grief and the pandemic, in order to investigate the main aspects and developments of grief, as well as possible questions and attempted answers and suggested solutions. To this end, the narrative review method was used. The electronic databases Portal de Periódicos of CAPES, Scielo and Pepsic were consulted, using the keywords “mourning”; pandemic"; “psychology” in the period from 2020 to 2022. After reading the articles found in the databases, 24 articles published in Brazil were selected, which, after qualitative assessment, resulted in the elaboration of four thematic categories, namely: “Loss and grief in the context of pandemic : care strategies”; “Mourning as a political event and collective experience”; “Psychology practices during the pandemic: adaptations and possibilities” and “Complicating elements in the grieving processes”. Analyzing the scientific production on grief during the Covid-19 pandemic allowed us to take a look at how some processes were experienced in this unique and, in many ways, challenging historical moment. Science played a crucial role in responding to urgent social, psychological, health demands, among others, that emerged daily. The scientific production on grief and pandemic between the years 2020 and 2022 presented several contributions to give us a glimpse into strategies for caring for psychological suffering, about the possibilities of exercising psychology in the face of a new reality, especially in a remote environment, and about some elements complications in the grieving process. Furthermore, a very important contribution of the studies was the analysis that mourning in the Covid-19 pandemic was an event crossed by political, social, cultural and economic issues, and was also a collective experience.

This study aims to explore and provide empirical evidence on how financial socialization directly affects financial knowledge, financial skills, and financial self-efficacy. Additionally, it investigates the relationships between financial knowledge, financial skills, and financial self-efficacy, while also examining the indirect influence of financial socialization on financial self-efficacy through the mediation of financial knowledge and skills. The research focused on a sample of 208 millennials from West Sumatra, selected through non-probability accidental random sampling. The data analysis utilized the partial least square structural equation modeling technique (SEM PLS) with SmartPLS 3.0. The findings revealed that the direct impact of financial socialization on financial knowledge and skills was statistically significant. However, the direct effect of financial socialization on financial self-efficacy was not deemed significant. The study also established the statistically significant impacts of financial knowledge and financial skills on financial self-efficacy, along with confirming the indirect influence of financial socialization on financial self-efficacy through the mediation of financial knowledge and skills.
„Chusta wiecznie zielona”. Pieta Teresy Ferenc. Studium wierszy
Authors: Janus Katarzyna
Published: February 2024

The article attempts to interpret several of Teresa Ferenc’s poems included in the volume Pieta, published in 1981. The selected works combine the motifs of home, mother and the girl who is the author’s porte-parole. Written from the perspective of the trauma experienced in childhood: the burning of the family village and the death of her parents, we find numerous biblical allusions and cultural contexts, the explanation of which is the subject of this study. An attempt has been made to demonstrate the richness of the poetic imagery, the source of which can be traced back to extreme experiences.

"Śpi jak młynarz na worku…" O językowo-kulturowym obrazie snu w polszczyźnie

Sleep, understood as a physiological need of man, accompanies him in accordance with the daily rhythm, the incidental disruption of which is not life-threatening. The important role of sleep is evidenced by the rich vocabulary assigned to it, as well as collections of sayings that interpret or use figuratively this aspect of physiology. An analysis of dictionary resources made it possible to extract from them more than 300 lexical units (nominalisms and verbalisms) denoting sleep neutrally (e.g.: nap, half-sleep, drowsiness; sleep away, sleep in, have a good sleep) and marked, including humorously (e.g.: snore, cop some Z’s, conk off, rack, wrap yourself like a pancake) or crudely. The image of sleep from a physiological perspective is also reflected in a total of over 240 proverbs of different origins and longevity in the Polish language. They interpret both the beneficial effects of sleep (e.g.: Sleep is your best friend; Get some sleep, tomorrow will be better) as well as its negative sides (e.g.: No one has made any money by sleeping; Those who sleep for a long time suffer from poverty). The dream motif is used in literature, mainly that intended for children, as a didactic aspect.
