In terms of self-care practices, 90 adolescents (69.8%) demonstrated adequate self-care practices, while 39 (30.2%) demonstrated inadequate self-care practices. Furthermore, Kendall’s Tau-b coefficient showed a significance value of p = 0.000 < 0.05, indicating the existence of a statistically significant relationship between the level of knowledge and self-care practices in the prevention of adolescent pregnancy. In conclusion, the level of knowledge is significantly associated with self-care practices for the prevention of adolescent pregnancy among adolescents from the San Andrés community, Itaya River, Iquitos, 2024.
- Tesis Título Profesional Open AccessInteracción genotipo ambiente en el rendimiento de grano y caracteres agronómicos de híbridos triples de maíz amarillo duro (Zea mays L.) en dos localidades de Maynas. Loreto. 2026(Universidad Nacional de la Amazonía Peruana, 2026) Hurtado Gomez, Carlos Enrique; Ramírez Chung, José Francisco; Gonzáles Vega, RodrigoThis study aimed to evaluate the genotype × environment interaction for grain yield and agronomic traits of six three-way maize hybrids and one single-cross tester hybrid (Zea mays L.) evaluated in two locations of Maynas Province, Loreto, Peru. The experiments were established using a randomized complete block design with four replications. Nine quantitative traits were evaluated: days to male flowering, days to female flowering, plant height, ear height, number of kernel rows per ear, number of kernels per row, ear weight per plant, grain weight per plant, and grain yield. Data were analyzed using descriptive statistics, normality and homogeneity of variance tests, individual and combined analyses of variance, Pearson’s correlation analysis, and principal component analysis. Location had a significant effect on phenological and morphological traits, whereas the hybrid × location interaction was not significant for any of the evaluated variables, indicating a stable performance of the genotypes across environments. Although no significant differences among hybrids were detected for grain yield, the three-way hybrids MW 9792, MW 9794, and MW 9793 exhibited the highest average grain yields (12.91, 12.64, and 12.03 t ha⁻¹, respectively), numerically outperforming the single-cross tester hybrid ATLAS 777. Pearson’s correlation analysis revealed a strong association between male and female flowering, while principal component analysis explained 65.4% of the total variation and confirmed the close association of hybrids MW 9792, MW 9794, and MW 9793 with grain yield and related agronomic traits. These results indicate that these three-way hybrids are promising genetic materials for further evaluation in breeding programs and agronomic validation under the environmental conditions of the Peruvian Amazon.
- Tesis Título Profesional Open AccessDosis de Zingiber officinale. Jengibre en el agua de bebida en los indicadores sanitarios y parámetros morfométricos en pollos Cobb 500, Loreto(Universidad Nacional de la Amazonía Peruana, 2026) Tuesta Amasifuen, Orianna Kiarella; Garay Vasquez, Herless EdsonIntensive poultry production in the Peruvian Amazon region faces the challenge of reducing the use of antibiotic growth promoters without compromising productivity. In this context, ginger (Zingiber officinale) emerges as a natural phytogenic alternative with proven antimicrobial, antioxidant and anti-inflammatory properties. The objective of the present research was to evaluate the effect of different doses of Zingiber officinale in drinking water on health indicators and morphometric parameters in Cobb 500 chickens in the Loreto region. A completely randomized design (DCA) was used with 100 chickens distributed in five treatments: T0 (0 ml/liter), T1 (4 ml/liter), T2 (5 ml/liter), T3 (6 ml/liter) and T4 (7 ml/liter), analyzing the data by ANOVA and Tukey's test at 5%. The results showed highly significant differences in stool consistency (p=0.000), with a progressive dose-response effect, and in body weight (p=0.000), where all treatments with ginger outperformed the control (1970.00 g), highlighting T3 with 2189.67 g. Thoracic circumference also showed significant differences (p=0.0012), with T2 being the most favorable with 42.17 cm. Height, tarsal and wing length did not present statistical differences. No treatment generated diarrhea, foot lesions, morbidity or mortality. It is concluded that the dose of 6 ml/liter of ginger optimizes body weight and is harmless for birds, positioning itself as a viable alternative to conventional growth promoters in Amazonian poultry farming.
- Tesis Título Profesional Open AccessEnseñanza de la filosofía y pensamiento crítico en los estudiantes del 5to año de secundaria de la institución educativa Maynas 2025(Universidad Nacional de la Amazonía Peruana, 2026) Wong del Aguila, Lorely; Zambrano Peña, Luis NiloThe present study aimed to determine the relationship between the teaching of philosophy and critical thinking in fifth-year secondary school students of the Maynas Educational Institution during 2025. The research followed a quantitative approach, with a correlational type and a non-experimental, cross-sectional design. The population consisted of fifth-year secondary students, to whom a structured questionnaire was applied to measure the variables teaching of philosophy and critical thinking, considering their respective dimensions. Descriptive and inferential statistical techniques were used for data analysis. The Kolmogorov Smirnov normality test indicated that the variables did not follow a normal distribution; therefore, Spearman’s Rho correlation coefficient was used for hypothesis testing. The results showed a strong, direct, and statistically significant correlation between the teaching of philosophy and critical thinking (ρ = 0.756; p < 0.05). Likewise, significant relationships were found between the teaching of philosophy and the logical (ρ = 0.660), dialogical (ρ = 0.653), and contextual (ρ = 0.643) dimensions of critical thinking. Regarding the dimensions of philosophy teaching, the formative purpose showed the highest influence on critical thinking (ρ = 0.686), while philosophical contents presented the lowest correlation (ρ = 0.509). It is concluded that philosophy teaching oriented toward an appropriate pedagogical approach, the development of thinking, and a comprehensive formative purpose significantly contributes to strengthening critical thinking in secondary education students.
- Tesis Título Profesional Open AccessEvaluación del caudal real en un conducto abierto usando cinco tipos de vertederos hidráulicos de pared delgada(Universidad Nacional de la Amazonía Peruana, 2026) Ricopa Aranibar, Maribel Varelie; Tamani Ricopa, Sara Esther; Suárez Rumiche, Jorge Antonio; Garcia Navarro, Matsen Rolando; Salas Barrera, Fernando JavierThe overall objective of this thesis was to evaluate the actual flow rate in an open conduit using five types of thin-walled hydraulic weirs: one rectangular, three triangular (45°, 60°, and 90°), and one trapezoidal. To achieve this objective, the theoretical flow rate in the open conduit was initially evaluated using equations derived from Bernoulli's equation. These equations express the theoretical flow rate as a function of the liquid level in the weirs and their geometric parameters, such as the opening angle in the triangular weirs, the opening width in the rectangular and trapezoidal weirs, and the angle of the side walls in the trapezoidal weir. Simultaneously, the flow rate in the inlet line to the open conduit was measured using a digital flow meter. Then, a linear regression was performed between the measured flow rate data and the theoretical flow rate data, obtaining the following discharge coefficients for each weir: 0.594, 0.6137, 0.6202, 0.6177 and 0.621, respectively. These were compared with those reported in other sources, revealing a high degree of similarity between them. Consequently, the actual flow rate of each weir was evaluated by multiplying the discharge coefficient by the theoretical flow rate. When comparing the measured and evaluated flow rates, the trapezoidal weir showed the lowest percentage error (0.24 %), while the 90° triangular weir registered the highest (7.77%). The results validate the derived equations and confirm the fulfillment of the general objective and the research hypothesis.
