This study investigates employees’ perceptions of occupational stress and its impacts within the operational units of the Glo-Djigbé Industrial Zone (GDIZ). Based on a sample of 427 respondents, distributed across four categories according to the formula proposed by J. P. Beaud and B. Marien (2003), and later adapted by J. E. G. Yetongnon and T. R. G. Kadjegbin (2020, p. 172), the data were processed using Excel 2021 to assess the predominance of opinions.

Cette recherche examine l’impact des choix et de l’utilisation des manuels de mathématiques par les enseignants de 7e et 8e d’éducation de base en République Démocratique du Congo sur l’enseignement et l’apprentissage. L’hypothèse posée suggérait que ces choix étaient influencés par la disponibilité des manuels, leur adéquation avec le programme scolaire et les préférences personnelles des enseignants.

Cloud computing is an evolving technology that provides data storage and highly fast computing services at very low cost. Data stored in the cloud is managed by cloud service providers, raising concerns about authenticity, reliability, and integrity. Unauthorized users may misappropriate or alter data. This paper proposes a secure public auditing scheme employing a Third Party Auditor (TPA) to authenticate the privacy, reliability, and integrity of data stored in the cloud.

For the sixth-generation (6G) mobile communication, the channel coding scheme is very important. To implement high-speed low-density parity-check (LDPC) coders and decoders, Field-programmable gate arrays (FPGAs) are widely used. The well-known practice is to develop a register-transfer level (RTL) model of a digital circuit, which requires extensive simulation and system verification, resulting in a long development cycle. Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) codes are used to correct transmission errors in digital communication systems.

Purpose: Automated urine output monitoring enhances accuracy and traceability in critical care, yet its implementation is often hindered by ergonomic and environmental barriers. This study evaluated the safety and usability of an automated monitoring system through a Human Factors and User-Centered Design (UCD) approach to identify factors influencing clinical integration. Methods: A prospective, multi-phase study was conducted following IEC 62366-1/2 standards. First, a PRISMA-ScR scoping review was performed to establish design requirements.

The present study examines the relationship between spiritual intelligence and financial well-being among university teachers, with a particular focus on the mediating role of mindfulness. In the context of increasing financial complexity, understanding the psychological determinants of financial well-being has become essential. A purposive sample of 250 university teaching faculty members from Rajasthan was selected based on specific inclusion criteria, including age, income, and work experience.

This paper presents a comparative analysis of the perceptual mechanisms between the human camera-type eye and the dragonfly compound eye, focusing on differences in optical structure, neural processing, and spatiotemporal interpretation. Humans possess a single-lens, high-acuity system optimized for static detail; dragonflies employ a multi-faceted compound eye (up to ~28,000 ommatidia per eye in large species) with low spatial but exceptionally high temporal resolution (critical flicker fusion ~200-300 Hz versus ~60 Hz in humans under bright light).

Dans un contexte post-conflit marqué par l’instabilité politique, les fractures sociales et la fragilité des institutions, l’Afrique subsaharienne fait face à un défi majeur : reconstruire des sociétés pacifiques et inclusives. L’éducation à la démocratie apparaît comme un levier stratégique pour favoriser la réconciliation, la participation citoyenne et la consolidation de la paix.
