The study investigated the relationship between requirements (V1) and operability (V2) of investment projects within the Putumayo River Basin Binational Special Project for Integral Development (PEBDICP). A basic, quantitative, descriptive-correlational methodology was used, with a non experimental, cross-sectional design, applying a questionnaire to a census sample of 42 workers from the institution. The general results, despite a perception of V1: Requirements as 'always' by 88%, revealed a moderate, direct, and statistically significant association (Pearson's r = 0.664; Sig. = 0.000) between both variables. This validates the general hypothesis, confirming that a significant relationship exists between the study variables. It is concluded that while excellent requirements management is fundamental, it does not in itself guarantee optimal operational performance, as this depends on other internal factors that must also be addressed directly.

This final report investigated the connection between business promotion management and new business formalization in the San Juan district for the year 2024. A descriptive-correlational study was conducted without an experimental approach. A survey of 292 merchants was conducted to collect data. The findings show that both business promotion management and business formalization are considered adequate, with 25% evaluating them positively. A moderate and positive relationship was identified between the various variables, with a Spearman coefficient of 0.727 and a significance level of 0.000. It will also be observed that technical support had a moderate influence, with a coefficient of 0.644, market access with 0.586, and access to technological services with 0.541, all with a significance level of 0.000. Finally, access to financing showed a coefficient of 0.639, equally significant at 0.000.

The objective of this study was to investigate the potential association between sexual dimorphism and the presence of a fourth canal in the permanent mandibular first molar (CCPMP). The sample consisted of 359 patients 204 females (56.8%) and 155 males (43.2%) who underwent cone-beam computed tomography (CBCT). The scans were obtained from the digital archive of a private dental practice in the city of Iquitos, Loreto, between 2018 and 2024. All tomographic images that met the established inclusion and exclusion criteria were included in the study. Axial, sagittal, and coronal tomographic sections were analyzed to assess the presence of the CCPMP, as well as the number of foramina and roots in the distal portion of the mandibular first molar. Statistical analysis was performed using SPSS version 27, applying Pearson’s Chi-square test with a significance level set at p < 0.05. The mean age of the study sample was 38.89 ± 16.28 years. The overall prevalence of the CCPMP was 16.7%, with 17.2% observed in females (35 of 204) and 16.1% in males (25 of 155), showing no statistically significant association with sex (p = 0.796). It is therefore concluded that no relationship exists between sexual dimorphism and the presence of a fourth canal in the permanent mandibular first molar.

This study aimed to analyze the relationship between iron-deficiency anemia and the severity of early childhood caries in children treated at the Primary Health Care Facility (IPRESS) I-4 “San Juan” during 2025. It was a quantitative, descriptive, cross-sectional study with a correlational design, conducted on a sample of 169 children under six years of age. Simple random probability sampling was used and the techniques used included reviewing the CRED service care books to obtain the children's hemoglobin levels and performing clinical dental evaluation. The collected data were coded and processed in a database using SPSS software, version 27.0. Pearson’s Chi square test (χ²) was applied for inferential analysis, with a significance level of p <0,05. Results showed that most children were 4 years old (43,8%), with a mean age of 4.1 ± 0,7 years, and a predominance of males (54,4%). A high prevalence of iron-deficiency anemia was observed, with mild (51,5%) and moderate (34,9%) forms being the most common, and an average hemoglobin level of 9.9 ± 0,8 g/dL. Regarding early childhood caries, the mean ceo-d index was 1,6 ± 0,9, with the low-severity category predominating (49,1%). No statistically significant association was found between hemoglobin levels and caries severity (p=0,767), nor was there a relevant linear correlation between these variables (ρ=-0,028; p=0,718). In conclusion, a high prevalence of irondeficiency anemia was identified in the studied pediatric population; however, no significant relationship was established with the presence or severity of early childhood caries.
