Introduction: Guided endodontics has emerged as an innovative technique for managing extraordinarily complex endodontic cases, particularly in teeth with pulp canal obliteration. This approach combines cone-beam computed tomography (CBCT) imaging with intraoral scans and three-dimensional digital planning to create customized guides that enable more precise and conservative access to the pulp chamber. Objective: To critically analyze the scientific evidence regarding the effectiveness of guided endodontics compared to the conventional technique. Methodology: A qualitative study was conducted through a systematic narrative review based on a structured search in indexed databases (PubMed, Scopus, Web of Science, SciELO, and Google Scholar), selecting 28 studies published between 2015 and 2025. Findings were grouped into four thematic areas: diagnostic accuracy, reduction of operator risk, clinical applicability, and educational projection. Results: Most studies agreed that this technique improves canal localization, reduces iatrogenic errors, and shortens operative time, especially among inexperienced operators. However, limitations were identified, particularly regarding technological dependency and methodological heterogeneity among the studies. Conclusion: Guided endodontics represents an effective and safe alternative for complex cases, although its implementation requires a critical evaluation of its clinical, technical, and educational feasibility. General field of study: Health Specific field of study: Dentistry Type of study: Systematic narrative review.

Potato purple top (PMP) is one of the most serious diseases affecting the potato crop in several countries of the Americas and the world; Candidatus Liberibacter solanacearum (CaLso) is the causal agent of this disease, which in recent years in Ecuador has caused significant economic losses. The management of PMP is focused on the control of the insect vector Bactericera cockerelli through the periodic application of insecticides. However, the use of seed from diseased plants can also cause the spread of the disease. This study complements the research that seeks to establish the percentage of disease transmission using seed tubers from plants with different symptomatology caused by CaLso in the potato variety Superchola. Thus, it was found that the percentage of transmission was 11.07% when tubers from plants with severe symptoms were used as seed, and if seed free of the disease was used, transmission was 0.06%. At the same time, a phenotypic scale was determined according to the degree of infection of the disease in parent plants.

Introduction. Technical and Vocational Education and Training (TVET) prepares people with the knowledge and skills necessary for their early immersion in the workplace. For this to happen, students need to obtain deep cognitive processes, such as conscious attention, understanding of basic concepts and student know-how; for the development of this knowledge, it is essential that teaching combines practice with a solid theoretical basis, thus promoting a meaningful connection between the knowledge acquired and its application in the productive sectors. Objective.  This study focuses on examining the relationship between the education received by technical high school graduates and their ability to enter the labor market, determining whether the competencies acquired during the school cycle are related to the demands of the productive sectors. Methodology.  This is quantitative correlational research with an explanatory level. It will determine the level of labor market insertion of students graduating from technical high school in Tourism, Agriculture and Agroindustry of the Educational Units: “Cuellaje”, “José Peralta” and “Apuela”, located in the rural area of the sector of Intag. Results.  The data show a certain mismatch between the training received in the technical baccalaureate and the demands of the labor market, since the graduates express a general dissatisfaction with their academic preparation, especially regarding the development of soft skills and the use of technology in which they show greater difficulty. It is therefore determined that for labor market insertion to be effective, it is necessary not only to prioritize technical competencies, but also to promote soft skills, such as leadership and teamwork, as well as to take advantage of more dynamic training strategies that are contextualized to the demands of the labor market. Conclusion. To ensure the professional success and salary satisfaction of graduates from technical institutions, it is crucial to align their training with the needs of the labor market. This implies a comprehensive approach that prioritizes the development of advanced technical skills, autonomous problem-solving abilities, and the strengthening of interpersonal skills and technological competencies. By addressing these areas, it is possible to close the existing gap and prepare graduates with the “know how to be and know how to do” determining an effective immersion in the productive sectors.

Introduction. The teaching-learning process in technical high school students faces numerous challenges, including lack of motivation, limited interaction between students, and the disconnect between practical and theoretical learning. This results in low levels of academic performance and insufficient preparation for the work environment. Objective. The general objective of this research was to demonstrate that the learning of technical high school students of the 15 de Agosto Educational Unit, under the implementation of group teaching strategies, fosters interaction, teamwork, and the development of technical and socio-emotional skills. The central problem identified was the lack of integration of collaborative methodologies that connect theoretical learning with practical and social skills, which affects students' academic performance and job preparation. Methodology The research used a quasi-experimental design, with a descriptive and correlational approach, and collected data from a sample of 120 students organized into three classrooms. During the second quarter of the 2024-2025 school year, all subjects implemented structured group activities. The information was analyzed using statistical tools, including the calculation of Cronbach's Alpha (0.815) and significant correlations. The results highlighted a moderate positive correlation (r = 0.525) between group strategies and collaborative learning, and a strong relationship between effective communication and problem solving (r = 0.811). It is concluded that group strategies significantly promote collaborative learning and develop socio-emotional skills, recommending strengthening communication, structuring activities and optimizing educational technologies to maximize pedagogical impact.

Introduction: This study explored the effectiveness of Cannabis sativa oil emulsions and agricultural oil with cannabis s. macerate for the control of Bactericera cockerelli nymphs, a pest that damages solanaceous crops in Ecuador, as a sustainable option to chemical insecticides, Bactericera cockerelli causes important losses in solanaceous crops spreading diseases such as "purple tip". The excessive application of chemical pesticides can lead to pest resistance, environmental contamination and high costs for agricultural producers. Objectives: with these components in consideration, the aim was to establish the insecticidal effectiveness of cannabis oil emulsions and agricultural oil with cannabis macerate, as well as to identify the ideal concentrations for the control of B. cockerelli nymphs. Methodology: The research took place at the Plant Protection Laboratory of the Technical University of Cotopaxi, Latacunga, Ecuador, under controlled conditions (21.5°C and 49% RH). A 3x2 Factorial design (DCA) with 8 treatments and 3 replications was implemented for the experiment. The types of oils represent Factor A (A1: cannabis oil; A2: agricultural oil with macerate) and the concentrations Factor B (0%, 15%, 25%, 50%). The procedure starts with the extraction of cannabis oil by steam distillation, in addition to preparing macerates and emulsions with Tween 80, and finally, exposing 60 nymphs for each treatment to evaluate their mortality in periods of time (1-10 minutes), the information collected was analyzed with the InfoStat 2020e program. Results: ANOVA statistical analysis and Tukey's tests (5%) showed that the following concentrations exhibited greater effectiveness: 15% showed 41% mortality of nymphs at 6 minutes (indicating extended persistence); at 25% nymph mortality was 47% at 4 minutes (fast acting). Increasing the concentration to 50% proved to be less efficient (32% at 1 minute), establishing that there are no major variations between oil types, but between concentrations. Conclusions: These findings support the application of cannabis derivatives as bioinsecticides. General area of study: Agronomy. Specific area of study: Plant Health. Type of article: original.
