This pilot study examines a ‘learning-by-teaching’ approach to teaching French as a foreign language, implemented in the first year of university in a course focused on written discourse (up to level B2 of the Common European Framework of Reference for Languages - CEFR). Working in small groups, the students prepared and delivered micro-lessons on French tenses and modes (present, future, imperfect, past tense, pluperfect, future perfect, subjunctive, imperative). The programme consisted of (a) a phase of acquisition and consolidation of grammatical knowledge (definitions, usage, exceptions), (b) the creation of examples and counter-examples, (c) the creation of targeted exercises, and (d) a presentation followed by a peer discussion. The data are based on a post-activity questionnaire (n = 10 responses out of 13 registrants), combining Likert scales, pre/post self-assessment and open-ended questions, as well as the teacher's observation notes. The results indicate an increase in reported understanding of the phenomenon (M before = 7.00; M after = 8.80; mean gain = +1.80/10), associated with a high perception of in-depth understanding, awareness of errors and ability to explain (M between 4.20 and 4.80/5). Thematic analysis highlights (1) the transition from ‘procedural’ knowledge to ‘explicable’ knowledge through the anticipation of questions, (2) the heuristic role of ‘pitfalls’ and counterexamples, (3) the regulatory value of collaborative work and feedback, and (4) an ambivalent affective dynamic (responsibility, stress, confidence). The article discusses the contributions of micro-teaching to attention to form, metalinguistic awareness and transfer to written production, and proposes avenues for methodological extension (triangulation with student productions, deferred measurements, sample enlargement).

Entrepreneurship is always a courageous act, but even more so in the digital realm. The emergence of businesses operating in the metaverse, with real-world patrimonial repercussions for participants, represents a new frontier in the field of strict liability for entrepreneurs. Can the conduct of the avatar be separated from that of the acting subject? If not, what possible grounds for exemption from liability would remain available to the entrepreneur?

Neuroscience tools aim to analyze individuals' unconscious responses to stimuli, whereas territorial marketing promotes the characteristics of places. This project seeks to integrate the two disciplines to evaluate the processes of identifying and enhancing territorial resources using neuroscientific tools. Using a mixed approach, a benchmarking matrix was developed, along with a pilot test comprising five stations and a Likert scale, which enabled optimization of the experimental protocol for subsequent stages of the study.

The study reviews the use of essential oil (EO) nanoemulsions (NEs) as an innovative and sustainable alternative for the postharvest preservation of fruits. It starts from the problem ofthe high perishability of fruits and the limitations of synthetic preservatives, as well as issues related to food waste. EOs, due to their antimicrobial and antioxidant properties, are promising; however, their direct application is limited by volatility and low solubility. Nanoencapsulation in the form of NEs improves the stability, controlled release, and efficacy of EOs, allowing their incorporation into biodegradable edible coatings. The work compiles and compares recent studies on different essential oils and polymeric matrices, showing that these coatings extend shelf life, maintain quality, and reduce the incidence of postharvest diseases in fruits such as apples, papayas, and strawberries. In addition, information gaps are identified, such as the lack of long-term toxicological studies, formulation optimization, scalability to a sustainable industrial process, and consumer acceptance. The study concludes that EO NEs represent a promising and sustainable alternative, but further research is required for their safe and effective industrial application

This work presents the geometric modeling, implementation, and experimental validation of basic upper-limb therapeutic trajectories using the KUKA KR6 R900 SIXX six-degree-of-freedom industrial robot. A complete kinematic model was developed based on the Denavit–Hartenberg formulation, including both forward and inverse kinematics equations for Cartesian trajectory generation, following classical principles of serial manipulator modeling [7], [8].

Three representative motions were implemented: elbow flexion, elbow extension, and forearm pronation–supination. Each trajectory was executed in 20 consecutive repetitions using the physical robot, and experimental validation was performed through direct measurement with a mechanical dial indicator gauge.

The results showed mean positioning errors of 0.08 mm for flexion, 0.09 mm for extension, and 0.11 mm for pronation–supination, with standard deviations of approximately 0.014 mm, confirming high repeatability and sub-millimetric spatial accuracy. These values are consistent with the expected geometric behavior of six-degree-of-freedom industrial manipulators [8], [9].

The findings validate the correct implementation of the kinematic model and demonstrate that the KR6 can execute basic therapeutic trajectories with high geometric precisión.

This work in progress analyzes institutional risk associated with organizational project management maturity in a high public investment environment. The case examines a Colombian territorial Education Secretariat that managed 63 projects between 2020 and 2024, representing between 40% and 62.8% of total municipal investment. The Project Management Maturity Model (PMMM) was applied to determine the formal maturity level of the organization. Results indicate that the organization does not formally surpass Level 1 according to strict PMMM criteria, revealing limited consolidation of foundational project management practices. Although operational functionality is present, the asymmetry between financial exposure and institutionalized methodology suggests structural governance vulnerability. The study proposes interpreting organizational maturity as a preventive institutional risk indicator in territorial public investment contexts.

This article presents the development of an innovative tool based on a geolocation-enabled web application designed to monitor and report domestic animals in vulnerable conditions. The primary objective is to centralize and validate citizen-submitted reports, thereby reducing response times and strengthening the operational capacity of rescuers, organizations, and relevant authorities. The methodology focused on building a functional prototype through the integration of state-of-the-art technologies, including a convolutional neural network (CNN) trained to automatically identify two animal categories—dogs and cats—along with interactive map-based visualization modules and database systems for report management.
The CNN achieved a peak validation accuracy of 98.75% and a final training accuracy of 98.55% for animal-category classification. In addition, usability and performance evaluations indicated stable operation and a favorable user experience.
Field tests were conducted in the province of Veraguas, Panama, to validate the prototype. The project represents a meaningful contribution to the adoption of technological solutions for animal protection, showing high user acceptance and strong potential for national-scale deployment, supporting community-based surveillance and the planning of more efficient interventions.

The research evaluated the physicochemical and microbial quality of water from the Virgen de Cocharcas spring in Matapuquio, Huancayo, Peru, intended for human consumption. Parameters such as fecal coliforms, total coliforms, Escherichia coli, conductivity, pH, salinity, and total dissolved solids were assessed at four different sampling locations. The findings indicated a lack of fecal contamination and the absence of Escherichia coli, signaling that the water is safe for consumption. Levels of conductivity, pH, and salinity were found to be appropriate for drinking water. Total, dissolved solids remained within established limits. In conclusion, the Virgen de Cocharcas spring in Matapuquio is suitable for human consumption, possessing excellent microbiological and physicochemical properties

The purpose of this study is to examine teachers' opinions on the use of TikTok as a digital tool and as a resource to help students learn French. More specifically, the objective is to discover teachers' opinions, their experiences, and what they find difficult to understand about integrating such teaching methods. In addition, this article highlights another major aspect to be overcome, namely technical obstacles, inadequate infrastructure, and teacher training. Ultimately, it attempts to offer teachers more opportunities to use digital tools more effectively in their teaching practices. The study adopts a qualitative approach that focuses on the descriptions of FLE teachers. The sample consists of twelve FLE teachers who work mainly in public and private middle and high schools in Greece, supplemented by elementary school teachers. Digital technology allows students to be independent, creative, collaborate with peers, and even be the class itself. The results also highlight the need for ongoing teacher training and well-designed policies to effectively use digital tools in education, particularly for the protection of learners.
