Seismic resistance in structural elements of rigid cores versus structural walls in a multi-family building in the city of Huancayo
type: item
description: The general objective of this research was to evaluate the technical feasibility of applying a rigid core system by comparing it to a structural wall system in a multi-family building located in the city of Huancayo. The methodology employed was a non-experimental, descriptive-comparative design. Numerical modeling was performed using ETABS software on two structural configurations for the same ten-story building on S2 soil in Seismic Zone 3: Model A (Distributed Stiffness Structural Walls) and Model B (Centralized Stiffness Rigid Core), both designed according to the guidelines of Technical Standards E.030 and E.060. The results of the static and dynamic analyses showed significant differences in mechanical behavior. The rigid core system generated a 14.34% increase in total seismic mass, resulting in a base shear force of 257.14 Tonf, exceeding the demand of the conventional system by 32.25 Tonf. In terms of lateral stiffness, the rigid core exhibited greater flexibility, registering higher interstory drifts (angles of drift) than the wall system. Specifically, in the transverse direction, the core reached an inelastic drift of 0.0070, placing it at the maximum limit permitted by Peruvian regulations. It is concluded that the application of the rigid core is technically feasible, strictly adhering to safety controls, although structurally it is less efficient and more demanding than the wall system. Its use is justified primarily by advantages in architectural functionality and space optimization.

Composite Index for Peruvian Business Reclassification Aligned with Industry 5.0
type: item
description: The objective of this research was to design and propose a business reclassification model for the Peruvian context, based on a composite index that includes economic, digital, technological, and organizational dimensions, as well as positioning, considering current Industry 5.0 trends. This is a propositional study with a non-experimental design, which employed a methodology of document review, literature review, and normative analysis. In addition, mixed techniques were used to construct the indicators. The proposed Composite Business Reclassification Index (CBRI) allows for the identification of the level of digital maturity, organizational efficiency, and business competitive positioning, overcoming the shortcomings of the current approach focused exclusively on sales and labor income. The main limitation of the study is its lack of empirical validation or the lack of validation by business and economic experts. However, the proposed model represents an original contribution by offering a business classification more consistent with current trends, with a potential impact on public policymaking. Therefore, its use is recommended to validate its usefulness for both business management and economic development.

Analysis of the Energy Matrix and its Transition toward Sustainable Development in Latin America
type: item
description: Energy is essential for human well-being, economic development, and environmental sustainability. In this context, the transformation of the energy matrix stands out as a key component of global efforts toward sustainable development. Latin America, with its high potential in renewable energy, plays a strategic role in this transition. However, the region’s strong dependence on fossil fuels continues to generate environmental impacts and hinders progress toward a cleaner energy matrix. This study analyzes the progress and challenges Latin America faces in its path toward a more sustainable energy transition. To this end, a detailed review of academic research, official documents, and updated statistical data was conducted. The findings reveal that approximately 57% of the region’s energy matrix comes from renewable sources—a figure that significantly exceeds the global average, estimated at 30%. Notably, countries such as Brazil, Uruguay, and Chile stand out for their growing use of wind and solar energy. Despite these achievements, structural and regulatory barriers persist, limiting the sector’s comprehensive development. Consequently, the study highlights the need for a more active role from the state through coherent public policies, effective regulatory frameworks, and sustainable incentives. This paper not only provides an updated characterization of the regional energy landscape but also proposes lines of action and research to strengthen the energy transition process in Latin America.

Determination of the enzymatic activity and the percentage of PPO inhibition in the carom sheets post-treated by blanching and osmodehydration
type: item
description: This study evaluates the enzymatic activity and the percentage of PPO Inhibition in starfruit slices treated with blanching and osmodehydration to improve their stability and quality. The research was carried out, applying a 2k factorial experimental design with two main factors: blanching time (10 and 30 seconds) and sucrose concentration (50 and 60 °Brix). The results showed that blanching time has a significant impact on the reduction of PPO enzymatic activity, with the 30-second treatment being more effective. On the other hand, sucrose concentration showed a minor influence, although it contributed to the variability of the data. The optimal treatment for PPO inhibition reached 82.76% with prolonged blanching and an intermediate concentration of sucrose. This shows that blanching is crucial to control enzymatic browning, while osmodehydration complements the process by limiting the availability of water for enzymatic action. It is concluded that the combination of thermal and osmotic treatments allows improving the physicochemical quality and enzymatic stability of the processed star fruit, suggesting the optimization of these variables for their application in derived products.

Leadership Style and Pedagogical Management in Education for the Work of Public Institutions
type: item
description: The research in question is basic and correlational, focusing on the relationship between leadership styles and pedagogical management in the educational field. A descriptive method with a correlational design was used to carry out the study. The sample was composed of 29 teachers from two secondary level educational institutions with a technical variant, belonging to the UGEL Junín. The main objective of this research is to determine the relationship between leadership styles and pedagogical management specifically in the context of education for work in these educational institutions. The data were obtained through the use of the Leadership Styles Questionnaire (CELID-A), as well as through a pedagogical management questionnaire. These instruments allowed to collect the necessary information to analyze the relationship between leadership styles and pedagogical management in the context of the research. In conclusion, it was found that the transformational leadership style is directly related to pedagogical management, evidenced by a value of r = 0.750, which indicates a high and direct positive correlation. On the other hand, the laissez-faire leadership style presents an inverse relationship with pedagogical management, with a value of r = -0.787, which indicates a high negative correlation and direct inverse. In contrast, the transactional leadership style does not show a significant relationship with pedagogical management, suggesting a low negative correlation. The transformational leadership style is the one that predominates in the Pedagogical Management in education for work of the educational institutions of the UGEL Junín. This approach is characterized by its ability to inspire and motivate teachers, promoting an environment of collaboration and continuous improvement in educational processes.
