- Tesis Título Profesional Acceso EmbargadoHerramientas financieras y su relación con la gestión de las MYPES en el sector comercial de Belén periodo 2024(Universidad Nacional de la Amazonía Peruana, 2026) Tapullima Panduro, Dorka Ruth; Uraco Huaymacari, Lesly Madahi; Ruiz Paredes, OttoThe present research aimed to identify the relationship between the use of financial tools and the effectiveness of the management of MSMEs in the commercial sector of Belén, period 2024, with a quantitative research approach, non-experimental cross-sectional design with a correlational scope, included as population and sample 190 people, including owners, partners, officials, professionals and workers of MSMEs in the Belén area, concluded that there is a high and significant positive relationship between financial tools and the management of MSMEs in the commercial sector of Belén (Rho = 0.779; p < 0.01), which demonstrates that the use of structured financial information strengthens planning, control and business decision-making, in addition financial analysis is positively and significantly related to business management (Rho = 0.673), showing that the evaluation of economic and financial indicators allows managers to understand the real situation of the business and improve their administrative performance; Taken together, the results confirm that financial tools not only fulfill an accounting function but are also strategic management instruments whose application contributes to the sustainability, competitiveness, and growth of SMEs.
- Tesis Grado de Doctor Acceso EmbargadoEstrategias motivacionales para mejorar el desempeño docente del Instituto de Educación Superior Tecnológico Público Pedro A. del Águila Hidalgo 2025(Universidad Nacional de la Amazonía Peruana, 2026) Bendezú Reyes, Carlos Andrés; Rios del Aguila, PerlitaThe study aimed to determine how motivational strategies improve teaching performance at the Instituto de Educación Superior Tecnológico Público Pedro A. del Águila Hidalgo, 2025. The research followed a quantitative, applied approach, using a pre-experimental design with a single group, pretest, and posttest, and a sample of 30 teachers. A validated 20 item questionnaire was used to collect data, which were analyzed using the Student’s t-test for related samples. The results showed significant improvements in all dimensions of teaching performance: the overall mean increased from 59,70 to 75,10 (t = -41,260; p < 0,001); in preparation for learning, from 14,63 to 18,70 (t = -21,948; p < 0,001); in teaching for learning, from 14,87 to 18,63 (t = -19,234; p < 0,001); in institutional participation, from 15,23 to 18,80 (t = -14,678; p < 0,001); and in professionalization and identity, from 14,90 to 18,97 (t = -24,553; p < 0,001). It is concluded that motivational strategies have a positive and significant effect on improving teaching performance, strengthening teachers’ commitment, professional identity, and educational quality.
- Tesis Título Profesional Acceso EmbargadoRelación entre el gasto de capital y la rentabilidad de la empresa Cervecería San Juan S.A en el periodo 2018 – 2023(Universidad Nacional de la Amazonía Peruana, 2025) Rojas Quinteros, Misael; Tuesta Atac, Lisbeth Eulalia; Young Gonzales, José RicardoThis research examines the relationship between capital expenditures (CAPEX) and the financial profitability of Cervecería San Juan S.A. during the 2018-2023 period. Through a quantitative and correlational approach, key indicators such as Return on Equity (ROE), Return on Assets (ROA), EBITDA, and net income were analyzed in relation to investments in fixed assets. The results indicate that CAPEX has a positive and significant impact on financial profitability, although the relationship varies in intensity depending on the indicator analyzed. A strong correlation was identified between CAPEX and net income, while its influence on EBITDA and ROA was moderate. Additionally, the effectiveness of capital expenditures was found to depend on strategic factors and the economic context. This study highlights the importance of carefully planning investments in fixed assets to maximize their contribution to financial performance. The findings not only reinforce previous theories on the relationship between investment and profitability but also provide a practical framework for optimizing CAPEX management in companies within the brewery sector, with significant implications for long-term sustainability and growth.
- Tesis Título Profesional Acceso EmbargadoFuentes de abono orgánico en el rendimiento de Brassica napus L. nabo. Zúngarococha, Loreto(Universidad Nacional de la Amazonía Peruana, 2025) Blas Romero, Sheyla; Cubas Encinas, OmarThe study addresses the growing concern about the negative effects of the excessive use of chemical fertilizers, such as soil degradation, environmental pollution and biodiversity loss. In response, organic fertilizers are presented as a sustainable alternative that improves soil structure and fertility, increases microbial activity, and reduces dependence on chemical inputs. The main objective of the research was to evaluate the agronomic performance of turnip in response to the application of three types of organic fertilizers: worm humus leachate, worm humus and chicken manure enriched with efficient microorganisms (Protowallpa). For this purpose, a completely randomized block experimental design was used, with four treatments and five replications. Variables such as plant height, extension, root diameter and length, leaf weight, total plant weight, root weight and expected yield per square meter were evaluated. The data obtained were analyzed by analysis of variance (ANOVA) and comparison of means using Tukey's test. The results showed that the worm humus and Protowallpa treatments were the most effective in promoting turnip growth and yield. In particular, these treatments produced plants with greater height, greater leaf spread, longer roots, and higher total plant weight compared to the control and the worm humus leachate. Plants treated with worm humus and Protowallpa reached average heights of 42.2 cm and 43.3 cm, respectively, compared to 36.7 cm for the control. Also, total plant weight was significantly higher in the humus (468 g) and Protowallpa (481 g) treatments compared to the control (263.15 g). Although the worm humus leachate showed a positive effect on some variables, such as roots weight and yield, its impact was lower than that of the other two organic fertilizers. The results suggest that worm humus and Protowallpa are viable options for improving turnip yield under the agroclimatic conditions of Zungarococha, highlighting the use of organic fertilizers, particularly worm humus and Protowallpa, which contribute significantly to turnip growth and yield, supporting their use in sustainable production systems.
- Tesis Título Profesional Acceso EmbargadoReserva de carbono mineral y orgánico en los tipos de suelo de la Ciudad Universitaria Zungarococha Loreto, 2024(Universidad Nacional de la Amazonía Peruana, 2025) Cardenas Rengifo, Giezi; Meléndez Celis, Ranulfo SegundoThe main objective of this research was to determine the mineral carbon reserve distributed in the types of mineral soil in the University City of Zungarococha, which allowed for the quantification of organic carbon and total carbon in the soils identified in the studied area. The work carried out based on test pits at representative points in the area allowed the horizons to be described following the methodology of the Soil Survey Manual. In addition, at least three different soil samples were taken for each test pit and analyzed in the soil research laboratory of the Natural Resources Research Center (CIRNA), and the results were recorded in an observation form and subsequently systematized in Excel spreadsheets. The research is descriptive in nature, and the results obtained have made it possible to describe and update the information on Amazonian soils in this area. It is stated that the soils show marked heterogeneity, with textures ranging from sandy to clayey, which influences their drainage, water retention, and carbon storage capacity. The surface horizons exhibit higher organic matter, darker colors, and higher carbon content (up to 2.6%), while the deep horizons have more clay and greater carbon stability but lower organic content. It was concluded that the calculation of total carbon per hectare confirms that more than 50% is concentrated in the surface horizons. It was concluded that the calculation of total carbon per hectare confirms that more than 50% is concentrated in the top 20–30 cm, and that finer soils store significantly more carbon than sandy soils.
