- Tesis Título Profesional Acceso EmbargadoRecursos interactivos en WhatsApp para promover el aprendizaje autónomo del inglés en estudiantes de quinto grado de secundaria en la Institución Educativa las Malvinas de Punchana 2025(Universidad Nacional de la Amazonía Peruana, 2025) Baquero Sandoval, Milagros del Carmen; Guzmán Cornejo, EdgarThis study evaluated the effect of using interactive resources in the WhatsApp application to promote autonomous English learning among fifth-year secondary school students at I.E.P. las Malvinas, Punchana district, 2025. The study was evaluative in nature, with a field-based approach, contemporary cross-sectional design, univariate variable type, and quasi-experimental with a control group. Its non-probabilistic population and sample consisted of 54 students, distributed between an observation group (31) and a control group (23). Data collection was carried out using a questionnaire adapted to a Likert scale with 88 items, which presented a Cronbach's Alpha reliability of 0.965. The post-test results showed that the average autonomous English learning score of the observation group was significantly higher than that of the control group (89.247 > 54.496). Therefore, it is concluded that the use of interactive resources on WhatsApp significantly improved the autonomous English instruction of fifth-year secondary school students (0.001 < 0.05).
- Tesis Grado de Maestro Acceso EmbargadoPrograma de habilidades comunicativas en directivos y docentes para el mejoramiento de la convivencia escolar de la Institución Educativa San Juan Bautista la Salle Requena 2025(Universidad Nacional de la Amazonía Peruana, 2026) Vasquez Caitimari, Joy Deivis; Rios del Aguila, PerlitaThe study evaluated the impact of a communication skills program on school coexistence through an applied research with a pre-experimental design involving 38 participants. The results showed a significant improvement in overall coexistence (mean 18,59 to 24.54; t=-5,632), with advances in affective relationship (mean 19,66 to 27,47; t=-4,434), academic relationship (mean 23.78 to 28,97; t=-3.457), and social relationship (mean 12,26 to 17,16; t=-5,581). All values were statistically significant (p<0,001),demonstrating the program's effectiveness in comprehensively improving school coexistence. It was concluded that the implementation of such interventions is presented as a valid and necessary strategy to foster a positive school environment
- Tesis Título Profesional Acceso EmbargadoHelmintos asociados a lesiones histopatológicas en juveniles de Brycon amazonicus, Agassiz 1829 “sábalo cola roja” Bryconidae, procedentes de la carretera Iquitos – Nauta, 2023(Universidad Nacional de la Amazonía Peruana, 2025) Alegria Loja, Bianca Julissa; Pizango Paima, Emer Gloria; Cabrera Soregui, Milagros AgustinaThe objective of this research was to identify helminth parasites associated with histopathological lesions in juvenile Brycon amazonicus "red-tailed shad" from the Iquitos-Nauta Road. Eighty specimens were analyzed during January-February 2023. The fish were transported in plastic bags from the fish farms to the Hydrobiology Laboratory of the Faculty of Biological Sciences at the National University of the Peruvian Amazon (UNAP), where biometric data, necropsy, and parasitological analysis were performed. Parasitological indices were determined according to Bush et al. (1997), while the analysis of histopathological lesions in gills, intestine, and pyloric caeca was performed according to Martins et al. (2018). The organs were fixed in 10% formalin and processed for histopathological analysis. The monogenean parasite Jainus amazonensis was identified in the gills, and the nematodes Procamallanus (S) inopinatus and Procamallanus (Dentamallanus) sp. were identified in the intestine and pyloric caeca, respectively. The monogeneans showed a prevalence of 52.5%, a mean intensity of 1.95, and a mean abundance of 1.02. while nematodes registered a prevalence of 41.25%, average intensity of 1.4 and average abundance of 0.58. The main histopathological lesions were found at the level of gills; intestine and pyloric ceca.
- Tesis Título Profesional Acceso EmbargadoCaracterización fisicoquímica y espectrométrica del aceite fijo de Oenocarpus bataua Mart. (ungurahui) comercializado en el mercado de Belén, Loreto 2022(Universidad Nacional de la Amazonía Peruana, 2026) Fernandez Vilchez, Cesar Miguel; Andrade Cauper, Jhoselyng Fatima; Sosa Amay, Frida Enriqueta; Jara Herrera, CletoIn the Amazonian lowlands, the Arecaceae family, with more than 240 genres, includes approximately 2,600 species of palm trees from which an oil is extracted and marketed that is highly sought after in the culinary, pharmaceutical, and dermo cosmetic industries; the oil from the fruit of Oenocarpus bataua Mart. (ungurahui) is a food highly valued for its nutritional and healing properties. The purpose of this research is to determine the physicochemical and chromatographic characteristics of the fixed oil of Oenocarpus bataua Mart., which is sold in the Belén market, Loreto. The research is descriptive in nature. The oil was extracted from randomly selected ungurahui fruits, yielding 15.15% oil with a density of 0.9117 g/mL. Through physicochemical tests and gas chromatography-mass spectrometry, the following results were obtained: acid value (mg KOH/g oil) 2.632 (mg KOH/g fat), peroxide value 8.7129 (meq O2/kg), iodine value 5.38 I2/100g oil, and saponification value = 222.5697 mg KOH/g oil. Five saturated fatty acids were identified (15.91%). 5 monounsaturated fatty acids (72.04%); 2 polyunsaturated fatty acids (12.06%); and 7 unsaturated fatty acids (84.10%). The physicochemical characteristics found are within the international range for oils. Furthermore, the chromatographic analysis identified oleic acid as the most representative component, being the most required in the cosmetics industry.
- Tesis Título Profesional Acceso EmbargadoEvaluación clínica del estado periodontal según el trimestre de gestantes en la IPRESS 9 de octubre-2025(Universidad Nacional de la Amazonía Peruana, 2025) Carrasco Babilonia, Maria Claudia; Vidaurre Urrelo, Jairo Rafael; Chávez Paredes, AlejandroThe present research aimed to clinically evaluate the periodontal condition according to the trimester of pregnancy in women attending the IPRESS 9 de Octubre during 2025, in order to identify the progression of periodontal alterations related to the physiological and hormonal changes of gestation. This was a descriptive, observational, and cross-sectional study involving a sample of 90 pregnant women equally distributed across the three trimesters of pregnancy. The Community Periodontal Index of Treatment Needs (CPITN) was applied to assess gingival bleeding, dental calculus, and the depth of periodontal pockets as indicators of periodontal health status. The findings revealed a progressive deterioration of periodontal condition as pregnancy advanced, with affectation rates of 80 %, 91 %, and 93 % for the first, second, and third trimesters, respectively. Mild conditions such as gingival bleeding and dental calculus predominated in early stages, while moderate and deep pockets increased in later trimesters, indicating a gradual worsening of periodontal disease. These results are consistent with several national and regional studies: Torres et al. (2021) in Lima found that 65 % of women in their third trimester presented gingival bleeding and periodontal pockets between 3–5 mm; Escalante et al. (2019) in Trujillo reported that the CPITN index rose from 1 to 3 between the first and third trimesters; and Salas Vargas et al. (2022) in Iquitos observed a 70 % rate of bleeding on probing, mainly during the second and third trimesters. It is concluded that pregnancy represents a biological and social risk factor for periodontal health, due to hormonal and immunological variations as well as insufficient oral hygiene habits during gestation. The results highlight the urgent need to incorporate preventive dental care and oral health education into prenatal programs, ensuring early detection and management of periodontal disease to safeguard both maternal and fetal well-being.
