Las empresas, en la actualidad, buscan utilizar un enfoque de mejores prácticas para ofrecer a los usuarios una mayor calidad de servicios de tecnologías de información (TI),y una menor cantidad de interrupciones de los mismos, teniendo como resultados clientes y/o usuario satisfechos. Un servicio de TI puede ser definido como un conjunto de funciones relacionadas que apoyan a las demás áreas de una empresa; este servicio puede consistir en hardware, software, y aplicaciones, pero los usuarios lo perciben como una sola unidad. El objetivo del desarrollo de esta investigación es la propuesta de un modelo de gestión de problemas basado en “Information Technology Infraestructure Library” (ITIL)versión tres, para la Dirección General de Sistemas (DIGESI) de la Universidad Peruana Unión Filial Tarapoto (UPeU FT). Según ITIL la gestión de problemas (PM), tiene la intención de ...

This study aimed to determine the relationship between carbon footprint levels and the knowledge, attitudes, and practices of secondary School students and the staff of a Private Denominational School. The research was carried out in three parts: the calculation of the carbon footprint of the school, following the methodology of the Protocol of Greenhouse Gases; the measurement of the carbon footprint in the study population, through the calculator of emissions of Dragonfly Management in Climate Change and Communication, and the application of a test of knowledge, attitudes and practices. The results showed that the emissions per year in the educational institution were 25.36 tCO2e and the average emission of the study population was 2.18 tCO2e. Thecorrelation analysis showed that there is a negative correlation of -0.228 between the carbon footprint and the knowledge, attitudes, and pra...

A total of 188,859 meteorological-PM10 data validated before (2019) and during the COVID-19 pandemic (2020) were used. In order to predict PM10 in two districts of South Lima in Peru, hourly, daily, monthly and seasonal variations of the data were analyzed. Principal Component Analysis (PCA) and linear/nonlinear modeling were applied. The results showed the highest annual average PM10 for San Juan de Mirafores (SJM) (PM10-SJM: 78.7 µg/m3) and the lowest in Santiago de Surco (SS) (PM10 -SS: 40.2 µg/m3). The PCA showed the infuence of relative humidity (RH)-atmospheric pressure (AP)temperature (T)/dew point (DP)-wind speed (WS)-wind direction (WD) combinations. Cool months with higher humidity and atmospheric instability decreased PM10 values in SJM and warm months increased it, favored by thermal inversion (TI). Dust resuspension, vehicular transport and stationary sources contributed m...
