This study, titled "Structural Vulnerability to Seismic Hazards in Housing in Zone X of Huaycán, Ate-Vitarte District, 2023," provides an in-depth evaluation of the seismic vulnerability of self-constructed housing within a highly seismic region of Lima. The methodology encompasses a comprehensive assessment of 2-, 4-, and 6-story residential buildings using compressive strength testing of concrete, which revealed a 30% deficiency relative to the E030 standard. To quantify collapse probabilities, advanced dynamic simulations and nonlinear analyses, including Incremental Dynamic Analysis (IDA), were conducted. The results indicate that 2- and 4-story structures are particularly susceptible, with an estimated collapse rate of 20.5% under extreme seismic conditions. Fragility curves further reveal that older constructions and those built without proper technical supervision are 45% more li...

El estudio titulado "Vulnerabilidad Estructural ante Peligro Sísmico en las Viviendas en la Zona X de Huaycán, Distrito Ate-Vitarte, 2023" tiene como objetivo: evaluar el grado de vulnerabilidad sísmica de las viviendas autoconstruidas en una región propensa a terremotos. Método: incluye la evaluación de edificaciones de 2, 4 y 5 niveles mediante pruebas de resistencia a la compresión del concreto, que revelaron que los valores estaban un 30% por debajo de los estándares establecidos en la normativa E030. Adicionalmente, se utilizaron técnicas de modelado y simulación para realizar análisis de respuesta sísmica, incluyendo pruebas dinámicas incrementales que permitieron identificar la probabilidad de colapso en estas estructuras. Resultados: indicaron que las estructuras de 4 y 6 niveles presentan un riesgo significativamente mayor de daño severo o colapso, con un...

Educational audiovisual media seek to facilitate dialogue, expression and participation of the main actors in the university classroom, both teachers and students, in the adoption of new practices that favor the development of classes. The objective of this study was to evaluate the impact of the use of educational audiovisual media on the academic performance of nursing students at a private university in Metropolitan Lima. The research focus is quantitative and the design corresponds to the descriptive correlational one. A sample of 123 nursing students of both sexes (112 women and 11 men) was considered. For data collection, a questionnaire was administered and a weighted averages record card was used; and for statistical processing, frequencies and percentages were used, as well as the normality test and the correlation inferential test. The results indicate that the use of education...
