    La presente tesis fue elaborada bajo la línea de investigación de desarrollo de software, bajo un diseño pre experimental en el cual se aplicó un pre y post cuestionario al grupo de estudio conformado por 85 personas (población) son padres de familia o representantes de los estudiantes; asimismo como se trabajó con una población pequeña se utilizó un muestreo no probabilístico, intencional. Se utilizó la metodología RUP. Esta tesis tuvo como objetivo general implementar un sistema de información, para mejorar el proceso de matrícula en la I.E Niño Dios. Sócota, Cutervo, Cajamarca, 2021. Para determinar si se cumplió el objetivo se realizó un análisis estadístico de los datos obtenidos de la aplicación del instrumento de investigación (encuesta) en el cual mediante los resultados obtenidos del pre cuestionario se determinó que el 54% está en desacuerdo que se continúe con el actual proceso de matrícula en dicha Institución Educativa, mientras que en el post cuestionario el 86% está totalmente de acuerdo que se continúe con el actual proceso de matrícula en dicha Institución Educativa, por otro lado, en los resultados obtenidos del pre cuestionario se determinó que el 53% está totalmente de acuerdo que se mejore el actual proceso de matrícula en la Institución Educativa, mientras que en el post cuestionario el 67.06% está en desacuerdo que se mejore el actual proceso de matrícula en la Institución Educativa. En conclusión, la implementación de un sistema de información mejoró satisfactoriamente el proceso de matrícula en la I.E Niño Dios. Sócota, Cutervo, Cajamarca, 2021; aprobando la hipótesis planteada y dando una adecuada solución al problema de investigación.Autofinanciamient

    The influence of posterior parietal cortex on extrastriate visual activity: A concurrent TMS and fast optical imaging study

    Get PDF
    The posterior parietal cortex (PPC) is a critical node in attentional and saccadic eye movement networks of the cerebral cortex, exerting top-down control over activity in visual cortex. Here, we sought to further elucidate the properties of PPC feedback by providing a time-resolved map of functional connectivity between parietal and occipital cortex using single-pulse TMS to stimulate the left PPC while concurrently recording fast optical imaging data from bilateral occipital cortex. Magnetic stimulation of the PPC induced transient ipsilateral occipital activations (BA 18) 24 to 48ms post-TMS. Concurrent TMS and fast optical imaging results demonstrate a clear influence of PPC stimulation on activity within human extrastriate visual cortex and further extend this time- and space-resolved method for examining functional connectivity

    Roles of contour and surface processing in microgenesis of object perception and visual consciousness

    Get PDF
    Developments in visual neuroscience and neural-network modeling indicate the existence of separate pathways for the processing of form and surface attributes of a visual object. In line with prior theoretical proposals, it is assumed that the processing of form can be explicit or conscious only as or after the surface property such as color is filled in. In conjunction with extant psychophysical findings, these developments point to interesting distinctions between nonconscious and conscious processing of these attributes, specifically in relation to distinguishable temporal dynamics. At nonconscious levels form processing proceeds faster than surface processing, whereas in contrast, at conscious levels form processing proceeds slower than surface processing. I mplications of separate form and surface processing for current and future psychophysical and neuroscientific research, particularly that relating cortical oscillations to conjunctions of surface and form features, and for cognitive science and philosophy of mind and consciousness are discussed

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
