Authors: Martínez-Corona Beatriz , Méndez-Cadena María Esther
Published: January 2025

Objectives: To understand the socio-demographics of ejido communities in the Sierra Nevada region of Puebla, Mexico, their social reproduction strategies within domestic units, their perception of climate change and its impact, and their interest in training on the subject.
Methodology: A questionnaire was administered to a probabilistic sample of 334 ejidatarios from ten ejidos in the municipalities of Calpan, Chiautzingo, San Nicolás de los Ranchos, and San Salvador El Verde; 16.2% of the ejidatarios in the sample were women and 83.8% were men.
Results: Of the 334 ejidatarios in the sample, 70% were between 46 and 75 years old and 97% declared they knew how to read and write. Their social reproduction strategies are agriculture (55.7%), selling labor force (23.7%), housewifery (9.3%), commerce (4.5%), and other activities (6.8%). Such diversification is associated with the impacts of climate change on agricultural production. In terms of land, 71% is owned by the ejidatarios, themselves, with 65% having a working area of 1-2 ha. A percentage as high as 89.8% of ejidatarios have heard about climate change, with 93.4% indicating personal and domestic unit affectations; 99.4% identified climate transformations, and 88.6% declared interest in training on the subject.
Study implications: Participants in the study showed motivation to learn about five thematic axes of climate change, fostering a commitment to continue producing collaborative knowledge and designing strategies to enhance the adaptation strategies of ejidos in the region.
Conclusions: There was consensus among participants on the perception of climate change and its effects. Climate change requires them to strengthen and develop adaptation strategies applicable to reproduction strategies. To do so, they need access to training and participation in the production of collaborative knowledge on the subject in the region.

The BRICS nations’ economies show that the countries are global financial powerhouses whose currency exchange rates and stock markets have influence globally. In this paper, the analysis of the forecast trends in both Currency Exchange and Stock Markets using a dual layered machine learning approach exposing models such as Long Short Term Memory (LSTM), Random Forest, Gradient Boosting and Support vector machines (SVM) is conducted. Their performance is tested twice, first on currency exchange and then on stock market data, to compare them on the basis of predictive power to deliver actionable insights. Each model is applied to currency and stock market data, separately, as the study mainly uses extensive historical datasets from BRICS economies. Benchmarking is done using metrics such as Mean Absolute Error (MAE), Root Mean Square Error (RMSE) and R-squared values. For currency exchange, LSTM turned out to be the most effective model as it can handle a sequence of time series data. The best performance for stock market forecasting was achieved by Gradient Boosting, which is adept at finding complex nonlinear relationships. Random Forest proved to be consistent across both Datasets but SVM was found to be challenged on Scalability and Data Complexity, with relatively lower accuracy. The research goes on to repeat the comparative analysis for each of the different models, to illustrate the subtle differences between machine learning techniques in their capacity to effectively process financial datasets of all varieties. Predictive accuracy and reliability is further enhanced to reconcile conflicting trends between currency and stock markets by creating an ensemble model of all algorithms. These findings provide a robust framework for informed decision making for stakeholders to identify the more stable and hence more profitable market in the BRICS context. The results of this study add to the expansion of application of machine learning to global finance by demonstrating how tailored algorithms can offer significant economic planning and investment strategy plans.
ВАЖЛИВІСТЬ РЕЛІГІЙНОГО СКЛАДНИКА У ФОРМУВАННІ НАЦІОНАЛЬНОГО СВІТОГЛЯДУ ПІД ЧАС ВІЙНИ
Authors: Карабінович Віталій Мирославович
Published: January 2025

Мета статті полягає у тому, щоб розглянути релігійний складник як засіб забезпечення національної безпеки України. Однією з найгостріших проблем сьогодення в контексті російсько-української війни є також і проблема гарантування безпеки у сфері релігії. Недооцінка цієї проблеми може призвести до загальнонаціональної кризи. Духовний та релігійний складники будь-якого суспільства здатні подолати кризові явища, змінити національну самосвідомість, реорганізувати в правильне русло, об'єднати та привести країну до перемоги навіть під час війни. Методологічною основою дослідження виступили як загальноісторичні методи дослідження, включаючи аналіз, синтез, так і спеціально-історичні методи. Водночас використано методи соціології, наприклад спостереження. Проведено дослідження впливу релігійних організацій на гармонізацію духовного життя українців, що є важливим чинником консолідації суспільства в подоланні кривавого ворога. У часи повномасштабної війни, яку розв'язала росія проти України, важливим чинником для досягнення перемоги є створення духовних засад, консолідації суспільства, переорієнтації свідомості людей на вищі цінності, збереження культурної, духовної, та громадянської ідентифікації українців. Саме духовні цінності стають особливо важливими та, можливо, навіть критичними для соціальної стабільності держави і стають провідними чинниками її сталого розвитку. Слід зазначити, що в Україні вже історично склалося так, що релігія як соціальний інститут активно сприяла консолідації українського етносу, зміцненню моральних засад та забезпеченню суспільної стабільності і солідарності. Як відомо, саме православ'я відігравало важливу роль у збереженні української національної свідомості. Під час національно-визвольних змагань Б. Хмельницького захист православ'я був одним із головних гасел українського козацтва, з яким воно виборювало свою державність. У висновках відзначено вплив релігійного складника на формування та забезпечення національної безпеки України. Дослідили значення релігійних організацій як основи консолідації духовного життя українців та довели, як важлива та, беззаперечно, цінна релігійна підтримка свідомості українців під час війни.
НИЗХІДНА СОЦІАЛЬНА МОБІЛЬНІСТЬ В УРСР: НА ПРИКЛАДІ ДИСИДЕНТІВ
Authors: Федик Лідія Богданівна
Published: January 2025

Мета. На основі спогадів дисидентів проаналізувати причини та наслідки низхідної соціальної мобільності в УРСР. Методи. У роботі використано загальнонаукові методи аналізу і порівняння, які дали змогу виявити канали соціальної мобільності для різних соціальних прошарків радянського суспільства; системний метод був використаний при з’ясуванні чинників соціальної мобільності в УРСР. Історичний метод дав змогу розглянути проблему соціальних ліфтів та напрямів їхнього руху в конкретних історичних умовах. Оскільки основним джерелом дослідження були спогади українських дисидентів, застосовано герменевтичний метод. Водночас біографічний метод через розкриття окремих аспектів життя людини дав змогу зробити узагальнений аналіз проблеми низхідної соціальної мобільності та здійснити емпіричне підкріплення висунених теоретичних положень статті. Результати. У процесі дослідження встановлено, що горизонтальна (просторова) соціальна мобільність у СРСР була ускладнена через обмеження, встановлені державою (паспорт, прописка). Найбільш дієвими соціальними ліфтами в СРСР була освіта та армія. Установлено зв'язок між класовим походженням і соціальною мобільністю. Показано, що зміна соціального статусу людини не завжди була умовою для зміни її матеріального становища. У процесі вивчення спогадів українських дисидентів виявлено, шо більшість із них походило із селянських або робітничих родин. Їхнім каналом соціального підйому була освіта. Однак обов’язковою умовою була участь у комсомолі, а в подальшому членство КПРС. Висновки. Як висхідна, так і низхідна соціальна мобільність була контрольована державою. Соціальний спуск був примусовим і супроводжувався втратою роботи і житла, можливості займатися професійною діяльністю. Сім'я та шлюб у випадку дисидентів, за умов втрати соціального статусу, призводили до соціальної деградації одного або всіх членів сім’ї.

The rapid advancement of communication technologies, such as satellite networks, mobile, internet, and terrestrial communications, has created an urgent need to protect sensitive data from potential attacks. This is particularly crucial as photos transmitted through unreliable channels may contain sensitive or confidential information. This study evaluates the effectiveness of the Advanced Encryption Standard (AES) algorithm implemented in Java and Node.js, focusing on their performance in data encryption and decryption. The research employs AES in Cipher Block Chaining (CBC) mode, using 128-bit keys for Java and 256-bit keys for Node.js. It utilizes the Java Cryptography Architecture (JCA) and Java Cryptography Extension (JCE) to create an optimized runtime environment with advanced cryptographic libraries. The result indicate that Java's AES-128 implementation is more efficient than Node.js's AES-256, particularly in terms of speed and data processing capabilities as seen in figure 11 taking Java 2.00ns to encrypt and decrypt before the Node.js algorithm that couldn’t complete the process but remain at 0.75ns. Suggesting that specific use case and requirements should be considered when choosing between the two platforms for AES encryption. Java generally outperforms Node.js in efficiency, but Node.js provides essential cryptographic functions through its built-in 'crypto' module. Overall, the research underscores the advantages of using the AES algorithm across these platforms while demonstrating the varying performance characteristics between them.

Published: January 2025

Water quality is inherently linked with human health, poverty reduction, food security, livelihoods, preservation of ecosystems, economic growth, and social development of societies. This study evaluated the groundwater quality of Gishiri-Katampe, Abuja-Nigeria using statistical and geospatial techniques for water quality indexing. The study also used hydro-chemical parameters, geographical information, and statistical analysis to assess groundwater pollution potential; identify the most vulnerable areas, and generate a groundwater quality map. The Canadian Water Quality Index, the GIS mapping of the water quality of Gishiri indicates that the Water Quality Index is within the range of 76.87 to 92.53. Similarly, the WQI is predominantly good (62%), indicating a minor degree of threat. However, 38% of the area is occasionally threatened (fair) on the Canadian scale. However, some areas are occasionally threatened (fair) with the corresponding WQI of 28% within the study area. Moreover, out of the 11 water quality parameters analyzed, 6 parameters (dissolved oxygen DO, turbidity, chemical oxygen demand COD, NO3, Na, and biological oxygen demand BOD) were identified as significant parameters as indicated by the correlation and regression analysis. This suggested that they strongly influenced the variability of the water quality.

Authors: Baltazar Armando
Published: January 2025

La calidad de vida es un estado ideal de bienestar personal que se compone de diversas dimensiones tanto objetivas como subjetivas que son afectadas por aspectos sociales, económicos y ambientales; a nivel individual y colectivo. Estas dimensiones son universales sin distinción, pero la atribución de un valor es individual, por lo tanto, puede variar entre individuos. El objetivo de este ensayo es abordar el surgimiento de la conceptualización de “calidad de vida” a partir de una cronología y antecedentes históricos que emergieron en el siglo XX. Mediante una revisión literaria realizada a través de las bases de datos de Scopus, SciELO, Google Scholar y Redalyc y una sucesión de hechos, se enuncian los hallazgos más relevantes con respecto a su constructo en las décadas del siglo XX. Asimismo, se analiza su abordaje de la “calidad de vida” en los objetivos de la “Nueva Agenda Urbana Hábitat III” y el “Plan de Acción Regional para la implementación de la Nueva Agenda Urbana en América Latina y el Caribe 2016-2036”.

Published: January 2025

Annona muricata (soursop) leaves are rich in antimicrobial compounds such as flavonoids, alkaloids, tannins, saponins, and phenols. This study aimed to develop a nanoemulgel formulation incorporating A. muricata leaf ethanol extract to enhance its efficacy against Propionibacterium acnes, a bacterium associated with acne vulgaris. Four nanoemulgel formulations containing varying concentrations of the extract (0%, 0.5%, 0.7%, and 1%) were prepared and evaluated for their physical properties (organoleptic, homogeneity, pH, spreadability, and viscosity) and stability through freeze-thaw cycles. The formulation with the highest extract concentration (Formula III) was selected for further characterization (particle size, morphology, and zeta potential) and antimicrobial testing against P. acnes. All formulations met the established physical property and stability criteria. Formula III exhibited a particle size of 20.5 nm and a zeta potential of 9.8 mV, indicating a stable nanoemulsion with well-dispersed particles. Antimicrobial testing revealed that Formula III demonstrated a strong inhibitory effect against P. acnes, with an average inhibition zone of 19.00 mm. These findings suggest that A. muricata leaf extract-loaded nanoemulgel has the potential to be a promising topical formulation for acne treatment. Further research is warranted to optimize the formulation and evaluate its efficacy in clinical settings.
Post-COVID Mucormycosis: An Emerging Threat in Developing Countries - A Prospective Review
Authors: Chakraborty Debpratim , Adhikary Sudipa
Published: January 2025

COVID-19, with its rapidly mutating strains, poses a significant global health challenge. Recent reports of a surge in mucormycosis cases among COVID-19 patients highlight the urgent need for understanding and addressing this critical complication. This review explores the factors contributing to mucormycosis development in COVID-19 patients and outlines strategies for prevention and management. Several factors, including high glucose levels (diabetes, onset, steroid-induced hyperglycemia), low oxygen levels, elevated iron levels (especially ferritin), metabolic acidosis, and diabetic ketoacidosis, can facilitate the germination of mucor spores. COVID-19 patients with underlying conditions such as diabetes, cancer, or organ transplants are particularly susceptible to mucormycosis due to their immunocompromised state. The growth of the mucor pathogen requires free iron, which is elevated in conditions like diabetic ketoacidosis. This elevated iron level promotes the formation of Cot-H, a crucial component of fungal growth, leading to mucormycosis. Additionally, comorbidities and corticosteroids can suppress the immune system, hindering the body's ability to fight off infections like mucormycosis. Therefore, it is imperative to avoid the indiscriminate use of corticosteroids. Strict control of acute hyperglycemia and comprehensive monitoring of diabetic and immunocompromised COVID-19 patients are essential preventive measures. By addressing these factors, healthcare providers can mitigate the risk of mucormycosis in COVID-19 patients and improve overall outcomes.

Result and Disscusions: The results indicate that gender is the most significant demographic factor affecting digital literacy, with females outperforming males in terms of digital skills (r = -0.154, p = 0.007). The study suggests that females tend to use technology more effectively for searching and evaluating information. However, age (r = 0.102, p = 0.041) and education level (r = 0.043, p = 0.365) did not show a significant influence on digital literacy, as evidenced by the ANOVA tests (F = 1.562, p = 0.211 for age; F = 1.003, p = 0.368 for education). This finding implies that access to and experience with digital technology is relatively uniform across different age groups and educational backgrounds.Furthermore, there was no significant relationship between social media usage and digital literacy (r = -0.054, p = 0.211), which may be due to the predominant use of social media for entertainment rather than educational or informational purposes. Conclusion: The study concludes that gender differences must be considered in designing digital literacy programs, and there is a need to encourage more purposeful and critical use of digital technologies among adolescents.

Phase change materials (PCMs) offer a viable approach for improving energy storage and thermal regulation in the construction industry. Despite their integration ease with building materials, PCMs face challenges with thermal conductivity. This study explores the effectiveness of different PCMs in reducing building energy consumption and investigates the role of nanoparticles in enhancing PCM conductivity. Specifically, the research evaluates three PCMs— N-octadecane, N-eicosane, and N-hexadecane—and examines the impact of two additives, Al2O3 and CuO, on thermal performance. Detailed analysis of temperature and heat flow parameters demonstrates that nanoparticle additives significantly enhance thermal conductivity and improve PCM absorption. Notably, higher nanoparticle concentrations result in delayed peak amplitudes by up to 1.5 hours and influence viscosity. Among the PCMs tested, N-hexadecane emerges as the most effective for improving winter thermal comfort in buildings, while N-octadecane is preferable for its melting point characteristics.

Tujuan penelitian ini menyajikan tentang pentingnya mengetahui keuntungan struktur organisasi matriks, dengan harapan dapat memetakan tujuan proyek yang jelas, penggunaan sumber daya yang efisien, informasi tak terbatas, dan pelatihan untuk manajer proyek. Struktur organisasi matriks lebih kompleks daripada struktur hierarki, tetapi memiliki banyak keuntungan. Metodologi atau Pendekatan yang digunakan dalam tulisan ini menggunakan metode atau pendekatan kepustakaan (library research), sedangkan pengumpulan data dilakukan dengan menelaah dan/atau mengekplorasi beberapa Jurnal, buku, dan dokumen-dokumen (baik yang berbentuk cetak maupun elektronik) serta sumber-sumber data dan atau informasi lainnya yang dianggap relevan dengan kajian. Temuan dalam kajian ini adalah terletak pada desain matriks yang menjadi pembeda utama dari desain struktur organisasi hierarki. Struktur organisasi matriks memiliki dua atau beberapa struktur pelaporan manajemen. Struktur ini adalah gabungan dari dua atau lebih struktur organisasi. Biasanya menggabungkan struktur fungsional (berbasis departemen) dengan struktur proyek (berbasis tim atau proyek). Desain organisasi matriks dapat memastikan kejelasan yang lebih mendalam tentang tujuan suatu proyek. Meskipun awalnya tampak membingungkan, anggota tim biasanya memiliki manajer utama untuk setiap departemen. Bedanya, dalam struktur matriks, anggota tim juga melapor kepada manajer proyek. Proyek sering kali membutuhkan pekerjaan dari anggota di sejumlah departemen seperti teknologi informasi, pemasaran, dan keuangan, dan maka oleh sebab itulah alasan setiap proyek sebaiknya memiliki manajer terpisah.
