Introduction. Teen Dating Violence (TDV) is a type of intimate partner violence with serious personal and family consequences. Objective. This study describes the prevalence of TDV victimization and perpetration (physical, sexual, psychological, and cyber), considering region, gender, and instruments. Methodology. A systematic review was conducted with PRISMA, using keywords and Boolean operators. Results. As a result, 12 studies were selected. South America presented the highest rate of psychological victimization (97.56%), physical perpetration (37.6%) and sexual perpetration (30.8%); Europe registered the highest rate of cyber victimization (72.6%). The female gender presented higher sexual victimization (12.3% and 52.5%), psychological victimization (1.5% to 64%) and cyber perpetration (53.2% and 56%); the male gender presented higher sexual perpetration (1.9% and 51.2%). The CADRI was used as a measurement instrument to assess TDV in 8 of the 12 selected studies. Conclusion. In conclusion, the results revealed great variability in prevalence rates by region, bidirectionality of TDV for both male and female genders, and the need to standardize instruments for future TDV research.

Introduction: The transformations that Salasaka traditional clothing exhibits today constitute an object of analysis from different theoretical perspectives that highlight it as a form of resistance and cultural identity. Other analysts defend the idea of transculturation. From a sociological and ethnographic position, this research is conducted, which aims to offer a particular view that integrates both visions. Objectives: The study is oriented towards a) Identifying the main symbolic elements of Salasaka clothing and their meaning within the community and b) Examining recent changes in the use of traditional clothing and the factors that have influenced its transformation. Methodology: A non-experimental, descriptive research project was conducted using a qualitative approach. In-depth, unstructured interviews were conducted with four community representatives and leaders. Participatory observation and visual analysis of traditional attire were also used. Results: The Salasaka traditional clothing constitutes an identity expression of the community, it includes its own symbols and traditions while maintaining immobile customs associated with its preparation and elaboration. The transformations regarding the decrease in its use and the pieces that comprise it are associated with a process of transculturation. Conclusions: Traditional Salasaka clothing is an expression of transculturation that incorporates modern trends without denying original traditions and beliefs. General study area: Communication.

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.
