(Universidad Nacional de la Amazonía Peruana, 2025) Yovera Monteza, Luz Amparo; Rios Mendoza, Silvia Raquel

The central objective of this study was to identify the link between parenting practices and the development of learning in the field of social personnel of children belonging to the Initial Educational Institution No. 174 “Mi Divino Niño”, located in Mariscal Ramón Castilla, in the year 2024. This work, of a quantitative nature, was framed within a relational approach, using a non experimental, descriptive and correlational design, with a cross-section. The sample was made up of all parents and children from the aforementioned institution, made up of 74 parents and 74 children. To collect the data, survey and observation techniques were applied, using a questionnaire and an observation guide as tools, which were previously validated by a panel of experts in the field. The findings obtained reflect that the implementation of appropriate parenting practices has a significant impact on children's social personal learning. This conclusion is supported by Spearman's correlation coefficient (Rho = 0.746), which showed a statistically significant relationship at a 95% confidence level.

Various groups of aquatic invertebrates inhabit the root systems of macrophytes; however, the representative groups are unknown. The objective was to understand the composition of aquatic invertebrates associated with the roots of Pistia stratiotes and Eichhornia crassipes. Samples were collected six times every two weeks from January to March 2024 in the Itaya River, Moena Caño community, Iquitos, Peru. Three sampling zones were established (zone 1: entrance to the channel, zone 2: middle section, and zone 3: end of the channel). Two sampling points were set up per zone: point 1: Pistia stratiotes, and point 2: Eichhornia crassipes. Five aquatic macrophytes were collected, making a total of 90 individuals per macrophyte. For microinvertebrate collection, macrophyte roots were manually squeezed, while for macroinvertebrates, the plant was placed in a white tray for root searching. Richness consisted of 9 phyla, 16 classes, 23 orders, and 37 families, with Arthopoda being the most diverse phylum and the orders with the largest families being Coleoptera and Hemiptera. Abundance was 19,559 individuals, with Arcellidae and Lecanidae being the most abundant; zone 3 was the most abundant, higher than the other zones. We concluded that there were no significant differences (p > 0.05) in the number of aquatic invertebrate families between the different zones, for both Pistia stratiotes and Eichhornia crassipes.

Niveles de gallinaza en las características vegetativas y rendimiento de Brassica oleracea L. Variedad Capítata, híbrido Blue Canyon. Loreto

The experiment was developed in a warm, rainy climate environment, in a soil with acid pH characteristics of clay loam texture located near the town of Zungarococha, Loreto. The statistical design applied corresponds to the DBCA, accompanied by its ANVA and Tukey's test, whose results led to the following conclusions: The application of poultry manure improved the vegetative characteristics and yield of the Blue Canyon cabbage to an optimal level of 60 t/ha. Doses higher than 50 t/ha of poultry manure showed positive effects on head weight with results of 1428 g and 589 g as was the case in T4. A direct relationship was observed between the application of poultry manure and the number of leaves. Stem length showed little variation between treatments, indicating a lower sensitivity to the variable studied compared to other variables. T4 with 60 t/ha of poultry manure obtained the best yield of heads/ha of 11,780 Kg.

Ergonomía del mobiliario de aula y su impacto en la salud postural de los estudiantes de la Facultad de Agronomía. Loreto 2024

At the Faculty of Agronomy in Loreto, there is a lack of evidence on how classroom furniture affects postural health, despite international and national reports of anthropometric mismatches and a high prevalence of musculoskeletal complaints. This study analyzes furniture ergonomics and its impact on students during 2024. It draws on literature documenting inadequate furniture and on INACAL’s Peruvian Technical Standards (NTP) that set design and safety requirements. Using a quantitative, non-experimental, cross-sectional, descriptive-correlational approach, a random sample of 265 students was surveyed and descriptive analyses, ANOVA, and MANOVA were applied. Findings show that 63.8% remain seated for more than 3 hours, 67.9% adopt inadequate postures, seat height (62.6%) and width (67.2%) are perceived as uncomfortable, and 78.9% report fatigue. MANOVA evidenced a significant effect of furniture width (p<0.001), and ANOVA associated width with lower-back and knee pain. It is concluded that furniture should be redesigned according to student anthropometry and NTP guidelines, prioritizing adjustable width and lumbar support to reduce fatigue and musculoskeletal risks and optimize learning.

Rondas infantiles y la comunicación oral en niños de la Institución Educativa Inicial N° 713, Yavarí 2025

The purpose of this research was to analyze the relationship between the implementation of children's rounds and the development of oral communication in children at Yavarí Early Childhood Education Institution No. 713, during the year 2025. The study was framed within a quantitative, basic approach and with a correlational design. The population consisted of 68 children from the initial level. For data collection, the observation technique was used, using a structured guide as an instrument validated through expert judgment. The results obtained through Spearman's Rho coefficient showed a positive correlation of moderate level (r = 0.551), which indicates that the more adequately implemented children's rounds are, the higher the level of development of oral communication in children. Furthermore, the bilateral significance value (p = 0.05) confirmed the existence of a statistically significant relationship between both variables with a confidence level of 95%, which allowed us to accept the research hypothesis. In conclusion, the study demonstrates that nursery rhymes not only encourage children's active participation, but also represent a valuable pedagogical strategy for stimulating oral language from an early age.
