- Tesis Título Profesional Acceso EmbargadoLos materiales educativos en los niveles de concentración en clases de inglés en estudiantes de quinto grado de secundaria en instituciones educativas públicas de Iquitos 2025(Universidad Nacional de la Amazonía Peruana, 2026) Torres Valera, Mishell; Guzmán Cornejo, EdgarThe present study aims to explain the influence of educational materials on the levels of concentration among fifth-grade secondary school students in public educational institutions in Iquitos, 2025. The methodology used was explanatory, with a field-based, cross-sectional, and multivariable design. The sample consisted of 300 students selected through stratified sampling with proportional allocation. Data were collected using valid and reliable questionnaires. The results showed that the mean concentration level was 62.058 on a vigesimal scale, corresponding to the “very high” category, as well as in its dimensions: superficial concentration (49.089), focused concentration (67.389), selective concentration (68.178), sustained concentration (60.222), and absorptive concentration (65.411). Regarding the educational materials variable, the results indicated a mean score of 70.692 on a scale transformed to 100. Likewise, the findings revealed a high and positive correlation of 0.720. Furthermore, the coefficient of determination (R² = 0.518) and the adjusted R² (0.513) indicate that 51.8% of the variability in concentration levels is explained by the combined use of educational materials (conventional, audiovisual, and new technologies). It is concluded that there is a positive influence between educational materials and concentration levels, with a significance value of p < 0.001 (p < 0.05). Therefore, the null hypothesis is rejected, confirming that the model is statistically valid for predicting the behavior of the dependent variable. High levels of concentration were observed with conventional and audiovisual materials, whereas lower levels were found with new technology-based educational materials among fifth-grade secondary school students in the district of Iquitos.
- Tesis Título Profesional Acceso EmbargadoDeterminantes de la calidad de vida en pacientes con hiperplasia prostática benigna en el Hospital III EsSalud, Iquitos 2026(Universidad Nacional de la Amazonía Peruana, 2026) Cubas Castillo, Ricky Walter; Rodríguez Ferrucci, Hugo Miguel; Padilla León, Marco AntonioObjective: To evaluate the determinants associated with quality of life in patients with benign prostatic hyperplasia (BPH) treated at Hospital III EsSalud Iquitos 2026. Methodology: Observational, descriptive, cross-sectional, and analytical study. Results: A total of 176 male patients participated, with a mean age of 69.26 years (SD=7.02). The mean quality of life index was 0.81 (SD=0.17). The most affected dimension was pain/discomfort: 62.5% reported mild pain. Regarding sociodemographic factors, physical activity (p=0.040) and comorbidities (p=0.043) showed a statistically significant association with quality of life; patients with intense physical activity had better quality of life (median=0.928), and those without comorbidities had better quality of life (median=0.93). A significant association was found between urinary symptom severity (IPSS) and quality of life, showing a clear inverse trend (mild: median=0.93; moderate: 0.89; severe: 0.81; p<0.001). Regarding complications, persistent macroscopic hematuria (median=0.75; p<0.001) and acute urinary retention (median=0.80; p=0.049) were associated with worse quality of life. Finally, a positive correlation was found between serum PSA levels and prostate volume (Rho=0.401; p<0.001). Conclusions: Quality of life in patients with BPH was determined by physical activity, comorbidities, urinary symptom severity, macroscopic hematuria, and acute urinary retention.
- Tesis Título Profesional Acceso EmbargadoEstructura horizontal y volumen maderable de las especies comerciales del bosque de colina baja de la comunidad nativa Buena Vista. distrito del napo. Loreto, Perú. 2023(Universidad Nacional de la Amazonía Peruana, 2025) Villar del Aguila, Renato Alexander; Rodríguez Gómez, Jorge LuisThe work was carried out in the low hill forest of the native community Buena Vista Napo District. Loreto Peru. A total of 378 trees were recorded, 06 commercial forest species and 06 botanical families, where the number of families is equal to the number of species. The Myristicaceae family contains the largest number of trees (153 trees), followed by the Fabaceae (72 trees) and Lauraceae (51 trees) families. Also, it is observed that the Cumala species reports the highest number of trees (153 trees); while a smaller number of trees contain Lupuna (12 trees). The timber volume by species of the low hill forest of the native community Buena Vista Napo District, Loreto Peru. Of the 06 species recorded in the forest census it was: that this forest contains a total volume of 2659.84 m3 for the entire area (476,087 Ha). Tornillo (927.15 m3), contains the highest volume value; On the contrary, Marupa (201.79 m3) and Lupuna (171.23 m3) have a lower volume. The species Cumala (85.74%) and Tornillo (69.93%) are the most ecologically important in the low hill forest of the native community Buena Vista Napo District, Loreto Peru; which make a total of 155.67% participation in the structure of this forest. Furthermore, it can be stated that one species reports little participation with less than 20% of IVI which is represented by the Lupuna species (19.81%). The Chi-square test (Table 12) shows a value of the comparator p= 0.004 lower than the significance level α= 0.05. This leads to rejecting the null hypothesis and accepting the alternative hypothesis that there is a significant difference in the value of the horizontal structure between species, at a significance level of α= 0.05.
- Tesis Título Profesional Acceso EmbargadoBiomasa y carbono almacenado en las especies forestales de los bosques localizados en las cuencas de los Ríos Amazonas, Ucayali y Napo, Loreto. 2021(Universidad Nacional de la Amazonía Peruana, 2022) Casique de la Cruz, Luis Manuel; Burga Alvarado, RonaldThe study was conducted in low-terrace forests located in the Amazon, Ucayali, and Napo river basins in the Loreto region of Peru, with the aim of estimating the above ground biomass and carbon stored by the forest species present in these ecosystems. The results show differences between the basins evaluated, suggesting variations in forest structure and the dominance of certain species. In terms of biomass, the estimated values reached 97,490.58 kg/ha in the Amazon basin, while the highest level was recorded in the Ucayali basin with 537,062.39 kg/ha. For their part, the forests associated with the Napo presented 408,409.50 kg/ha. This behavior indicates that the accumulation of organic matter is not homogeneous among the areas studied, which may be related to ecological factors such as tree density, size of individuals, and floristic composition. When analyzing the contribution of species, it was observed that M. coriacea stood out in the Amazon basin with 23,854.20 kg/ha of biomass, while N. glabra reached 137,455.56 kg/ha in the Ucayali. In the Napo, F. insipida registered 69,678.39 kg/ha. In contrast, P. parilis (58.15 kg/ha), V. multinervia (82.89 kg/ha), and O. olivacea (174.26 kg/ha) had lower values. With regard to carbon storage, 48.75 tC/ha were estimated in the Amazon basin, 268.53 tC/ha in the Ucayali, and 204.20 tC/ha in the Napo. Among the species with the highest contributions were M. coriacea, V. elongata, N. glabra, C. spruceanum, and F. insipida, while P. parilis, V. multinervia, and O. olivacea recorded minimal contributions, confirming the importance of Amazonian forests as carbon reservoirs.
- Tesis Título Profesional Acceso EmbargadoRelación entre la gestión emocional del personal y el manejo del estrés laboral en organismos públicos de la región Loreto durante el periodo 2025(Universidad Nacional de la Amazonía Peruana, 2026) Felix Camiñas, Debhora Coraima; Lopez Pinedo, Ana Vanesa; Ramirez Gómez, RolanThe objective of this research was to analyze the relationship between staff emotional management and work-related stress management among public sector employees in the Loreto Region. A quantitative, correlational methodology was employed, with a total of 184 records analyzed. Data were examined through Spearman's rank correlation coefficient, revealing a strong, negative, and statistically significant relationship (rho = -0.844, p = 0.021) between emotional management and perceived occupational stress, indicating that higher emotional competencies are associated with lower stress perception. Regarding specific hypotheses, adaptive regulation was negatively correlated with perception of work overload (rho = -0.789, p = 0.038), while emotional awareness and clarity showed a positive relationship with emotion focused coping (rho = 0.681, p = 0.030). Contrary to expectations, empathy and interpersonal management were positively correlated with avoidance strategies (rho = 0.615, p = 0.022). In conclusion, the development of emotional competencies is an essential resource for reducing work-related stress, although certain skills, under specific conditions, may be linked to unanticipated adaptive responses to organizational demands.
