Tic y rendimiento académico de educandos de secundaria, en una entidad académica de Lima, 2023

En marzo de 2020, la pandemia de COVID-19 llevó a Perú a una rápida transición hacia la educación a distancia mediante tecnologías de la información y comunicación (TIC). Esta investigación tiene como objetivo evaluar la relación entre el uso de TIC y el rendimiento académico de estudiantes de secundaria en una institución educativa (IE) de Lima. Se empleó un enfoque cuantitativo y un diseño no experimental de tipo básico. La muestra fue de 157 alumnos de una población total de 240. Se usó una encuesta con preguntas cerradas y escala Likert como instrumento. Los resultados revelaron una relación positiva de intensidad moderada entre las TIC y el RA, respaldando la importancia de desarrollar habilidades digitales específicas. El estudio sugirió ajustes pedagógicos para optimizar la influencia de las TIC en el RA. La hipótesis de investigación, que postulaba una relación directa y moderada entre las TIC y el RA, fue respaldada por un valor significativo (sig=0,000 < 0,005) y un coeficiente positivo (r=0,503), confirmando la relación y su grado significativo moderado. La investigación resalta el impacto positivo de las TIC al cerrar brechas educativas y preparar a los estudiantes para desafíos del siglo XXI, esenciales para el progreso socioeconómico sostenibl

Propuesta de infraestructura técnica de seguridad para un Equipo de Respuesta ante Incidentes de Seguridad (CSIRT)

Resumen: En este artículo se describe una propuesta creada para proteger la información y la infraestructura de un equipo de respuestas ante incidentes de seguridad (CSIRT), el cual es una organización dedicada a dar respuesta a incidencias de seguridad en tecnologías de la información. Un CSIRT está conformado por un grupo de expertos en seguridad de la información la cual provee de servicios como alertas y advertencias, tratamiento de incidentes, observatorio de tecnología, auditorías de seguridad, cómputo forense, entre otros. Por lo tanto, se hace uso de información sensible como datos de usuarios y de empresas que deberá tener fuertes métodos de seguridad. En este artículo se aborda una propuesta de los aspectos de seguridad que debe tener un CSIRT abarcando las áreas de Telecomunicaciones, Equipo hardware y Sistemas SIEM (Security Information and Event Management). Esta propuesta no toma en consideración la tipología en la que un CSIRT puede establecerse. Palabras clave: Seguridad, CSIRT, infraestructura, seguridad en redes

Student overcrowding in the Unified General High School of the city of Cuenca-Ecuador

La Unidad Educativa Fiscal Fray Vicente Solano se encuentra ubicada en la ciudad de Cuenca-Ecuador, considerada una institución de gran prestigio y larga trayectoria prestando sus servicios a la comunidad estudiantil de jóvenes ecuatorianos y extranjeros. El problema de esta investigación es el excesivo número de estudiantes hacinados dentro de las aulas de clase de dicha institución, por la falta de atención y control de parte de los entes reguladores del Ministerio de Educación, los cuales asignan números elevados de estudiantes a las unidades educativas, esto trae consigo efectos negativos en el rendimiento académico de los alumnos. El objetivo que persigue este estudio, es diseñar un plan de mejora, que beneficie a quienes se educan en esta Institución Educativa. En el plano metodológico, la investigación es de tipo descriptiva con enfoque cuantitativo, la misma que aplicará el método deductivo, por tal motivo se desarrollan encuestas dirigidas tanto a estudiantes como docentes del plantel. Los resultados arrojan que un mayor interés y correcto análisis por parte del Ministerio de Educación reduciría de manera más rápida y efectiva todos los efectos negativos encontrados, junto a ello, al contar con un menor número de estudiantes dentro del aula, existiría mayor interés por parte de los mismos por estudiar, por tal motivo es imperativo aplicar un plan de mejora estudiantil. Con la elaboración de esta investigación se logrará que la Unidad Educativa recupere su nivel académico de excelencia el cuál la ha caracterizado a lo largo de sus años de trayectoria, formando estudiantes con estándares de calidad.The Fray Vicente Solano Educational and Fiscal Unit is located in the city of Cuenca-Ecuador, considered an institution of great prestige and long history serving the student community of young Ecuadorians and foreigners. The problem of this research is the excessive number of students crowded into the classrooms of that institution, due to the lack of attention and control by the regulatory bodies of the Ministry of Education, which assign high numbers of students to the educational units, this brings negative effects on the academic performance of students. The objective of this study is to design an improvement plan that will benefit those who are educated in this educational institution. On the methodological level, the research is of a descriptive type with a quantitative approach, the same as the one that will apply the deductive method, for this reason surveys are developed aimed at both students and teachers of the campus. The results show that a greater interest and correct analysis by the Ministry of Education would reduce more quickly and effectively all the negative effects found, along with this, having fewer students in the classroom, there would be greater interest on their part to study, for this reason it is imperative to implement a plan for student improvement. With the elaboration of this research, the Educational Unit will be able to recover its academic level of excellence which has characterized it throughout its years of trajectory, forming students with quality standards

Rendezvous in cislunar halo orbits: Hardware-in-the-loop simulation with coupled orbit and attitude dynamics

Space missions to Near Rectilinear Halo Orbits (NRHOs) in the Earth-Moon system are upcoming. A rendezvous technique in cislunar space is proposed in this investigation, one that leverages coupled orbit and attitude dynamics in the Circular Restricted Three-body Problem (CR3BP). An autonomous Guidance, Navigation, and Control (GNC) technique is demonstrated in which a chaser spacecraft approaches a target spacecraft in a sample southern 9:2 synodic-resonant L2 NRHO, one that currently serves as the baseline for NASA's Gateway. A two-layer guidance and control approach is contemplated. First, a nonlinear optimal controller identifies an appropriate baseline rendezvous path for guidance, both in position and orientation. As the spacecraft progresses along the pre-computed baseline path, navigation is performed through optical sensors that measure the relative pose of the chaser relative to the target. A Kalman filter processes these observations and offers state estimates. A linear controller compensates for any deviations identified from the predetermined rendezvous path. The efficacy of the GNC technique is tested by considering a complex scenario in which the rendezvous operation is conducted with an uncontrolled tumbling target. Hardware-in-the-loop laboratory experiments are conducted as a proof-of-concept to validate the guidance algorithm, with observations supplemented by optical navigation techniques

Characteristics of undergraduate dental theses defended in Peruvian licensed universities and factors associated with their publication

IntroductionIn Peru, the defense of a university thesis allow to obtain a professional degree and demonstrate the research skills of the aspirant.ObjectivesTo characterize the undergraduate dental theses defended in Peruvian universities and those published in scientific journals, as well as to identify the factors associated with their publication.MethodsA cross-sectional, analytical and observational study was conducted using a search strategy in Google Scholar. We ascertained whether the theses defended between 2015-2018 had been published in scientific journals. Prevalence ratios (aPR), 95% confidence intervals (CI 95%) and p-values were obtained using generalized linear models.ResultsMost of the theses were defended in private universities (65.9%), located in the provinces (76.7%), in 2017 (32.1%). The most studied line of research was Dental Education (n = 418; 18.4%). Of the total number of defended theses (n = 2,267), only 130 (5.7%) were published, in a total of 41 scientific journals, of which 22 are specialized in the dental field. The 130 articles received 443 citations, with an average of 3.4 citations per document. The Universidad Católica Santa María was the institution that defended the most theses (n = 372); however, the Universidad Científica del Sur presented the highest percentage of published theses (36.4%). Theses with case-control (aPR: 2.74; CI 95%: 1.07-7.01; p = 0.036) and cohort (aPR: 3.51; CI 95%: 2.02-6.11; p  &lt; 0.001) methodological design had a higher frequency of publication; on the contrary, those executed in the community were less frequently published (aPR: 0.39; CI 95%: 0.17-0.93; p = 0.033), as well as, those with two researchers (aPR: 0.41; CI 95%: 0.18-0.92; p = 0.031), adjusted for two variables.ConclusionOnly one in twenty theses was published. Publication was associated with the type of methodological design, the place of execution and the number of researchers
