Variation of Free Residual Chlorine in the Drinking Water Distribution Network of Santa Ana, Huancavelica
Free residual chlorine is a fundamental indicator of the sanitary quality of drinking water because it ensures the persistence of the disinfection process throughout distribution and contributes to the protection of public health. In this context, the aim of this study was to evaluate the variation of free residual chlorine in the drinking water network of the Santa Ana neighborhood, Huancavelica. The research was applied in nature, with a quantitative approach and an explanatory level. The study population consisted of the drinking water distribution network, considering a sample of 180 households supplied by the Millpo and Ichu water sources. Free residual chlorine concentration was determined through direct measurements using a digital colorimeter at different monitoring points distributed from the reservoirs to the farthest sectors of the network. The results showed a progressive decrease in free residual chlorine concentration as the distance from the reservoirs increased. In the Millpo supply system, the average concentration decreased from 1.78 mg/L to 1.09 mg/L, whereas in the Ichu supply system it decreased from 1.96 mg/L to 1.51 mg/L. Statistical analysis revealed significant differences among the evaluated monitoring points (p < 0.05). It was concluded that there is a significant variation in free residual chlorine throughout the distribution network and that the recorded concentrations exceed the recommended values for human consumption, highlighting the need to optimize chlorine dosing and operational control within the drinking water supply system.

Effect of different substrates on the productivity and chemical composition of hydroponic barley fodder
The limited availability of permanent forage and the scarce use of substrates in the region motivated the evaluation of the effects of barley, wheat, and oat straw on hydroponic green barley forage (HGF) regarding its productive parameters and chemical composition. The study was conducted at the guinea pig experimental center of the Professional School of Animal Science under greenhouse conditions with controlled temperature and humidity. The results showed a significant effect (p < 0.05) of the substrates on root, shoot, and biomass production, with barley straw producing the highest root and biomass yields, whereas shoot production was similar among substrates. No significant differences (p > 0.05) were observed in plant height or root length. Regarding chemical composition, significant effects (p < 0.05) were found on root dry matter, organic matter, inorganic matter, crude protein, and neutral detergent fiber (NDF), as well as on shoot organic and inorganic matter. However, no significant effects were detected for shoot dry matter, crude protein, or NDF. The control treatment (water only) exhibited higher chemical composition values than the substrate treatments, except for root organic matter and shoot and root inorganic matter. It is concluded that the substrates selectively influence the productivity and nutritional quality of hydroponic green barley forage.

Effectiveness of Biological Examination According to Hymenal Types in Victims Under 18 Years of Age of Sexual Offenses. Medical-Legal Unit, Huancayo – 2025
Objective: To determine whether the effectiveness of biological examinations is conditioned by hymenal types among victims under 18 years of age of sexual offenses treated at the Huancayo Medical-Legal Unit during 2024. Methods: A quantitative, applied research study with an explanatory scope was conducted. The deductive-inductive and analytical methods were applied through a non-experimental, cross-sectional, causal design. The study population consisted of 93 victims under 18 years of age evaluated for sexual offenses at the Huancayo Medical-Legal Unit between January and September 2024. A census sampling approach was used, including all available cases. Data were collected through documentary analysis of medico-legal records and biological examination reports. Statistical analyses were performed using SPSS version 27, applying binary logistic regression to assess the causal relationship between hymenal type (independent variable) and biological examination effectiveness (dependent variable), considering a significance level of p<0.05. Results: Among the 93 evaluated victims, 65.6% (61) were from urban areas and 34.4% (32) from rural areas. Regarding educational level, 73.1% (68) had secondary education and 26.9% (25) had primary education. The most frequent age was 15 years (25.8%; n=24), followed by 14 years (20.4%; n=19) and 12 years (10.8%; n=10), with a mean age of 14.51 years. Inferential analysis showed that hymenal type does not condition the effectiveness of biological examinations among victims under 18 years of age of sexual offenses (p=0.000). Conclusion: The findings indicate that biological examination effectiveness is not determined by hymenal type identified during medico-legal assessment, suggesting that anatomical characteristics of the hymen are not a determining factor for obtaining biological evidence in sexual offense cases involving minors.

The air we breathe is polluted with physical and chemical components as a consequence of the car fleet, a problem that seriously impairs the quality of life of urban residents. The objective is to demonstrate the impact of the car fleet on air pollution and the health of the urban population. The present literature review focused on the topic of air pollution for the search of scientific information, both in its heuristic and hermeneutic phase, collecting information from scientific journals, based on online data collection techniques. Among the air pollutants emitted by motor vehicles, particles with a calibre less than or equal to 10 microns are identified as PM-10 and particles with a calibre less than or equal to 2.5 microns are identified as PM 2.5. The reduction of 50 ppm in the sulphur content of fuel and the introduction of cleaner fuels such as compressed natural gas or liquefied petroleum gas has led to a significant reduction in the values of carbon dioxide, nitrogen dioxide, carbon monoxide and sulphur dioxide, while remaining below the maximum permissible limits. It is concluded that about 90% of air pollution is due to motor vehicles.

Reliability of a test to evaluate the institutional identity of students entering the Faculty of Educational Sciences of the Daniel Alcides Carrión National University, Pasco
University identity is a multifaceted construct that reflects the mission and vision of an educational institution, shaped by its geographic, legal, and social context, and enriched by its philosophy, history, traditions, and symbols. This “seal of identity” fosters a sense of belonging and commitment among faculty and students. According to Pierre Bourdieu, “rites of institution” are essential to connect members to the university, establishing a “duty to be” that shapes their identity and responsibilities. University identity implies not only belonging, but also knowledge and participation consistent with the institution's mission and values, integrating and regulating its members within a psychological, historical, and cultural framework

Physicochemical Assessment of Drinking Water Quality in the Rural Communities of San Carlos, Viñas, and Pampas, Tayacaja: Implications for Safe Supply
Water is a vital resource for both human health and social and economic development; however, its quality can be compromised by adverse environmental conditions and human intervention. Significant challenges still persist regarding access to safe drinking water, especially in rural areas where treatment and monitoring systems are often limited. Within this context, the present study aimed to evaluate the physicochemical characteristics of water intended for human consumption in the population centers of San Carlos, Viñas, and the district of Pampas, located in the province of Tayacaja, Huancavelica. A descriptive and quantitative methodological approach was applied, using a stratified sampling design that covered various points in the distribution system, including catchment sources, reservoirs, and supply networks. Physicochemical indicators such as pH, turbidity, electrical conductivity, temperature, and residual chlorine were examined, and the results were compared against the limits established by national regulations. The findings revealed temporal variations in water composition, with particular emphasis on fluctuations in turbidity and residual chlorine levels. Although the recorded values generally remained within acceptable ranges, latent public health risks were identified, linked to inconsistent disinfection and the presence of suspended solids.

Relationship between emotional intelligence and managerial skills in peruvian accountants
Introduction: Emotional intelligence (EI) and managerial skills (MS) are crucial for performance in accounting. In Peru, research is limited, but globalization and digitalization have increased the demand for soft skills, making EI essential for organizational success in the Peruvian socioeconomic context. The objective was to determine the relationship between EI and MS of graduates from the Professional School of Accounting at the National University of Huancavelica (UNH), period 2014-2017. Methodology: This study used a non-experimental transactional correlational design to examine the relationship between EI and MS in 72 graduates. A validated questionnaire with a Cronbach's alpha of 0.88 was used to measure EI dimensions (intrapersonal, interpersonal, and adaptability). Data were analyzed using SPSS software version 25. Results: 66.7% of participants showed a normal level of EI, and 22.2% an elevated level. Spearman's correlation analysis indicated a positive and significant correlation between EI and MS (ρ = 0.775, p < 0.01), suggesting that 69.0% of MS can be explained by EI. The dimensions of adaptability (ρ = 0.749), intrapersonal (ρ = 0.743), and interpersonal (ρ = 0.718) showed significant correlations with MS. Conclusion: The UNH should integrate the teaching of EI into their curricula to better prepare students for the labor market, thereby improving their professional performance and strengthening the accounting sector in Peru.

Entrepreneurship and Agribusiness Elements in the MYPEs
Entrepreneurship and agribusiness elements in MSEs represent a field of great importance for economic and social development, especially in the agricultural sector; however, many microenterprises face challenges related to informality, low competitiveness and limited knowledge about the key elements of agribusiness, leading to a high rate of closures in their first years of operation. The aim was to systematize information on the relationship between entrepreneurship and agribusiness in MSEs, highlighting the elements that influence their sustainability and success, such as technological innovation, training and access to markets. We reviewed and selected scientific articles in databases such as SciELO and Scopus that met the inclusion and exclusion criteria, analyzing such research from a heuristic and hermeneutic perspective of the state of the art. Among the results, it is highlighted that the strengthening of entrepreneurial capacities and the integration of technology in productive processes are determining factors for the success of agribusinesses in microenterprises. It is concluded that there is a significant relationship between entrepreneurship and agribusiness development, and that MSEs that manage to integrate these elements have greater possibilities of growing and maintaining themselves in the market, improving their competitiveness.

Pro-environmental attitude and its relationship with Environmental Education in Students of a Public Higher Pedagogical Institute in Peru
The research was framed within: Determining the relationship between pro-environmental attitudes and environmental education in students of the Academic Program of Intercultural Bilingual Primary Education at a Public Higher Pedagogical Institute in Peru. The research was basic in nature, descriptive in level, and used a descriptive-correlational design. The population consisted of 300 students, and the sample comprised 85 initial teacher training students with voluntary acceptance and current enrollment and regular attendance in cycles I, III, and V. Students on medical leave were excluded. Non-probabilistic, intentional sampling was used. The instruments used were the pro-environmental attitudes questionnaire and the environmental education questionnaire. These instruments resulted from collaborative construction, drawing on diverse experiences such as those of Saza Quintero et al. (2021), who conducted a study on pro-environmental behavior and environmental knowledge in university students, and Carranza Gonzales (2022), on environmental education and awareness in higher education students. Content validity was established through the judgment of three experts dedicated to the field of environmental education, as well as methodological validity. Reliability was calculated using Cronbach's alpha coefficient, which measures the internal consistency of the items, with a value of 0.832, indicating appropriate reliability for its application. The results showed that: the majority of students (60%) had a high pro-environmental attitude, while a minority (40%) had a medium pro-environmental attitude overall. It was also found that the majority presented a high pro-environmental attitude in both its anthropocentric (55.3%) and ecocentric (74.1%) dimensions. Similarly, it was evident that the majority of students presented a medium level of environmental education (47.1%). Finally, the correlation between pro-environmental attitude and environmental education is significant with a p-value of 0.000 < 0.05 and a score of 0.603*. Whereas: the correlation between pro-environmental attitudes in their Anthropocentric and Ecocentric dimensions with environmental education was significant (p < 0.000), with scores of 0.594* and 0.523* respectively, being significant in both cases. All of this allows us to highlight the importance of safeguarding environmental education as a key component in initial teacher training, especially in intercultural contexts, in order to promote practices and values oriented towards sustainability.

Se realiza una revisión sobre los sistemas de riesgos de desastres por inundaciones, ya que son fundamentales para prevenir, mitigar y responder a las amenazas relacionadas con las inundaciones. Estos sistemas de riesgos son una combinación de medidas preventivas, de preparación y de respuesta que buscan minimizar el impacto de las inundaciones en la vida de las personas y la infraestructura. La clave está en identificar los riesgos, monitorear, alertar tempranamente, planificar, el ordenar territorialmente, mantenimiento de la infraestructura de control de inundaciones, la concientización, desarrollar planes de respuesta ante inundaciones, implementar programas de recuperación, como se realizará la reconstrucción, la cooperación regional, nacional e internacional. Se concluye que los sistemas de gestión de riesgos de desastres por inundaciones son un componente esencial de la resiliencia de las sociedades ante este tipo de amenazas naturales. Su implementación adecuada puede marcar la diferencia entre la tragedia y la seguridad de las comunidades afectadas por inundaciones, al permitir una respuesta organizada y una recuperación más rápida después de un evento catastrófico.

Improving the Performance of Rigid Pavements by Using Modern Methods in Layer Optimization
This article seeks to identify and analyze the modern methods implemented to date to improve the structure of rigid pavements and achieve optimal long-term performance. To achieve this objective, an investigation was carried out in which 30 articles were selected following inclusion and exclusion criteria. These articles cover aspects related to the design, construction and maintenance of rigid pavements. During the analysis carried out, it was found that there are various techniques and approaches available to address the improvement of rigid pavements. It was observed that seemingly insignificant factors, such as weather conditions and heavy traffic, can have a significant impact on the life and performance of these pavements as time passes and loading is repeated. Among the methods identified, innovative approaches were found that involve the use of new materials, advanced design techniques, efficient construction methods and preventive maintenance strategies. These methods seek to guarantee the durability, resistance and load capacity of rigid pavements, as well as minimize the negative effects of aging and wear. The study highlights the importance of properly implementing these modern methods in the planning and execution of rigid paving projects. Applying effective design and construction practices, as well as an appropriate maintenance program, can extend the life of rigid pavements and ensure better long-term performance.
