- Tesis Título Profesional Acceso AbiertoRelación entre los factores socioeconómicos y la tributación en la región Loreto en el periodo 2023(Universidad Nacional de la Amazonía Peruana, 2025) Salvador Garcia, Vianca Mariana; Pizango Rosales, Lui Mattias; Solsol Hidalgo, Edgar AlbertoThis research analyzes the relationship between socioeconomic factors and taxation in the Loreto region during 2023. Using a non-experimental design and a quantitative correlational approach, key variables such as education level, income, and compliance with tax obligations in income and property taxes were evaluated. The sample consisted of 57,381 individuals from the economically active population, and statistical tests, such as the Spearman correlation coefficient, were employed to test the hypotheses. The results revealed a positive and significant relationship between socioeconomic factors and taxation, highlighting the critical role of income and education in tax compliance. However, limitations such as high informality, tax ignorance, and distrust in public institutions were identified, restricting the effectiveness of the fiscal system. The findings emphasize the need for comprehensive policies that strengthen education, promote formalization, and enhance transparency in the management of fiscal resources. This research provides relevant evidence for designing strategies that not only optimize tax collection but also foster sustainable socioeconomic development in Loreto.
- Tesis Título Profesional Acceso AbiertoSupervivencia, crecimiento y calidad de planta de Simarouba amara Aubl. “Marupa” en diferentes sustratos orgánicos en vivero. Puerto Almendra, Loreto, Perú – 2024(Universidad Nacional de la Amazonía Peruana, 2025) Souza Mendoza, Giovanni Aldair; Alván Ruíz, Jorge ElíasThe objective was to determine the survival, growth, and quality of Simarouba amara Aubl. seedlings grown in different organic substrates in a nursery. Puerto Almendra, Loreto, Peru – 2024. The study was carried out at the Puerto Almendras nursery of the Faculty of Forestry Sciences – UNAP; four organic substrates and a control were used. The height, diameter, survival, and quality of Simarouba amara Aublet “marupa” seedlings were evaluated. The results indicate that the greatest increase in height was recorded in the substrate 40% chicken manure + 40% natural soil + 20% sand, with 10,8 centimeters. The diameter increase was 0,6 millimeters in the control, where seedlings were planted in 100% natural soil. Seedling survival in the trial was also better in the control, with 53% live plants. Finally, the quality of the seedlings at the end of the trial was generally poor.
- Tesis Título Profesional Acceso EmbargadoFactores asociados a mortalidad en pacientes con Insuficiencia Renal Aguda en hemodiálisis en una Unidad de Cuidados Intensivos en un hospital de la amazonia peruana, 2024-2025(Universidad Nacional de la Amazonía Peruana, 2026) López Reyna, Angel Bryan; Baldeón Ríos, Jorge Luis; Vásquez Lozano, EduardoAcute kidney injury (AKI) in critically ill patients is a frequent complication in the intensive care unit (ICU) and is associated with high mortality, especially when renal replacement therapy is required. The aim of this study was to determine the sociodemographic, clinical, and laboratory factors associated with mortality in patients with AKI undergoing hemodialysis in the ICU of Hospital EsSalud III–Iquitos from January 2024 to December 2025. A quantitative, retrospective cohort study was conducted; 64 patients aged ≥18 years with AKI requiring hemodialysis were included. In-hospital mortality was 62.5% (40/64). The median age was 69 years (IQR: 60–75), and 62.5% were male. The most frequent attributed etiology of AKI was sepsis (64.1%), and sepsis predominated as the attributed etiology among those who died (72.5% vs. 50.0% in survivors). In bivariate analysis, clinical sepsis (RR 1.82; p = 0.024) and mechanical ventilation (p = 0.029) were significantly associated with mortality; shock showed a trend (p = 0.077), whereas comorbidities, AEIOU criteria, mean arterial pressure, urine output, and laboratory variables (albumin, creatinine, urea, CRP, procalcitonin, hemoglobin, lactate, potassium, sodium, and leukocytes) showed no significant association. Among patients discharged alive (n = 24), at the time of data collection, 8 (33.3%) had died during follow-up, 9 (37.5%) remained alive on hemodialysis, and 7 (29.2%) were alive without hemodialysis. These findings demonstrate high mortality in ICU AKI requiring hemodialysis and highlight sepsis and the need for mechanical ventilation as key clinical components of mortality risk.
- Tesis Título Profesional Acceso AbiertoInterculturalidad e inclusión social de la actividad policial en pobladores Tikunas asentados en localidad de Santa Rosa, distrito De Yavarí, provincia de Ramón Castilla 2025(Universidad Nacional de la Amazonía Peruana, 2026) Dolly Flores, Jhony; Rengifo Ruiz, Roger ErnestoThis thesis, “Interculturality and Social Inclusion in Police Activity among Tikuna People Settled in the Locality of Santa Rosa, District of Yavarí, Province of Ramón Castilla, 2025,” examines the relationship between police activity and members of the Tikuna Indigenous people in a border Amazonian context. The study adopts a qualitative approach with an ethnographic design, using participant observation, semi-structured interviews, and field records, involving Tikuna community members and police officers from the local police station. The findings indicate that interculturality is expressed in a discontinuous manner and depends largely on the individual conduct of police officers. From the Indigenous perspective, respect, listening, and clarity in communication are key criteria for evaluating police performance. Linguistic barriers, limited recognition of cultural practices, and variability in police treatment generate fear and distrust, restricting effective access to the police station and weakening perceptions of social inclusion. From a social anthropology perspective, this study offers a situated understanding of the interaction between the State and Amazonian Indigenous peoples, highlighting the need to strengthen police practices grounded in an intercultural approach that articulates legal enforcement with recognition of local forms of organization and communication.
- Tesis Título Profesional Acceso AbiertoNivel de conocimiento en conservación y aspectos sociales de los humedales en los entornos de la ciudad de Iquitos, Loreto, 2025(Universidad Nacional de la Amazonía Peruana, 2025) Vilca Michi, Elvita Mical; Romero Villacrez, Juan LuisThe descriptive level research, which has the main objective of evaluating the population's perception of the conservation of the Amazon wetlands located in the surroundings of Iquitos, was carried out in the El Porvenir human settlement, Pampachica, and a sample of 179 inhabitants was interviewed, whose results reflect that 37.6% are aware that their homes are located in a place that was previously a wetland. Likewise, 37.1% and 20.3% express agreement and total agreement that these areas host species of plants and birds. Similarly, during flooding periods, when fish are present, migratory birds are observed, reflected in 25.4% and 11.7% in agreement and total agreement, respectively. These ecosystems represent aesthetic and scenic beauty for the areas (37.1%). The population is aware that local policies must be implemented for the conservation of these ecosystems, with 27.9% and 28.4% agreeing and strongly agreeing respectively. However, the residents express that they rarely (56.3%) observe species of economic importance in these ecosystems.
