Esta tesis presenta el estudio de la reducción de los contaminantes atmosféricos (MP10, MP2.5, CO, SO2 y NOx) por el uso del gas natural; así como el impacto en el sector salud (reducción de enfermos por vías respiratorias), en el sector económico (reducción de costo de inasistencia laboral y costo por atención por salud), en Huánuco al 2040. Se realizó un estudio detallado del parque automotor considerando el ingreso del gas natural en la matriz energética desde el año 2004, de enfermos por contaminación atmosférica, gastos asociados a la salud de las personas, luego se realizaron cálculos de emisiones mediante los factores de emisión como herramienta principal en este estudio y se realizaron los pronósticos mediante los cálculos estadísticos al 2040. Se concluyó con una propuesta de inversión a la conversión del parque automotor hacia el gas natural consiguiendo f...

The objective of the research was to determine the relationship between teaching performance and academic satisfaction of students at a public university in Huánuco. It was a study with a correlational quantitative approach. 87 university nursing students were surveyed during 2019. The instruments used were the scales: teaching performance and academic satisfaction, previously validated and reliable. Ethical considerations for research were applied. Descriptive analysis was performed and the bivariate analysis was using the Spearman Rho statistical test for a p value ≤ 0.05 and 95% confidence. In general, the teaching performance perceived by nursing students reached a regular level in 81.6% (71 students), likewise, 12.6% (11 students) indicated good performance and 5.7% poor performance. Regarding academic satisfaction, the medium level prevailed in 87.4% (70) and high satisfaction i...

Solid waste management is one of the main environmental challenges in cities around the world due to factors such as population growth and consumption habits. One of the main tools for the design of waste management projects is the estimation of per capita generation, however, the traditional method to obtain this information demands a lot of effort and time, therefore this research proposes an alternative approach to estimate per capita generation based on socioeconomic factors. For this purpose, socioeconomic demographic information and information on the per capita generation of solid waste of 50 families was collected, subsequently the variables that have significant influence were determined from the correlation coefficient ρ of Spearman for numerical variables and an ANOVA for categorical variables with an acceptance threshold of 0.4 and 0.05 respectively. The selected variables w...

Esta investigación se ejecutó en la escuela de Sociología de la Facultad de Ciencias Sociales de la Universidad Nacional Hermilio Valdizan (UNHEVAL), tomando una muestra de 12 docentes; se pudo apreciar la existencia de un perfil bajo Empowerment, en diez indicadores establecidos en la investigación. Luego de seis meses de implantar las acciones de mejora por la administración, en la escuela de Sociología, pudimos apreciar la existencia de un perfil relativamente alto Empowerment en la unidad académica, en nueve de 13 indicadores. Se pudo verificar la hipótesis, donde el uso adecuado del Empowerment como herramien-ta de gestión mejora la toma de decisiones en la escuela de Sociología; se apreció que el empowerment es más que un estado de la mente, más que un conjunto de comportamientos en equipo incluso más que políticas organizacionales; se apreció que al cambiar a empow...

This study demonstrates the benefits of implementing video analysis (VA) in physics instruction. It aims at demonstrating that the implementation of VA, in addition to being a low-cost and easy-to-use technique, significantly improves students’ understanding level of graphs in kinematics (ULGK). The study compares the results obtained after applying the Test of Understanding Graphs in Kinematics (TUG-K) on a practical kinematics class in a traditional lecture against one conducted using VA, in order to evaluate the influence of VA on students’ ULGK. The population was comprised of 60 students, 30 per group, from the School of Engineering of the Universidad de Huánuco. The results show that a strong, highly significant point-biserial correlation (rpb = 0.809) (p < 0.0001) exists between these two variables, that VA has an average impact on the ULGK (Hake = 32.5%) and that the ULGK...

An educative experiment was realised on healthful feeding, with the aim of demonstrating the adoption of positive nutritional habits by the usuary mothers of students of the CLAS Chinchao, Acomayo, during the 2011. The sample conformed 93 mothers, distributed in groups experimental and control, selected probabilistically, of simple random form. For the data collection we applied to a guide of interview and a card of physical evaluation. The descriptive analysis, was realised with measures of central tendency and the inferencial by means of statistical the Z of Wilcoxon, x2 of Mc Nemar, and Marginal Homogeneity, at a level of confidence to 95% and ≤ p 0.05, supported in software SPSS V20 for Windows. Significant differences were demonstrated [Z = -2,236; 0.025 p =], in the nutritional state, between groups and moments of the study, in addition in the experimental group, the changes (ran...
