La investigación desarrollada tuvo como propósito general determinar el índice del uso de papel por estudiante en la Universidad Nacional Hermilio Valdizan en el año 2011, ya que a la fecha no existía información al respecto y era necesario contar con ella, puesto que constituye de muchísima importancia en nuestros tiempos como un instrumento de gestión ambiental. Para el desarrollo se determinó una muestra a partir de la población estudiantil inscrita en el año académico 2011; el muestreo dio como resultado submuestras que estaban constituidas en función a la cantidad de estudiantes de cada Escuela Académica Profesional de la sede principal de la Universidad. Para la recogida de datos se usó un instrumento (encuesta) que fue validado por el grupo de investigación y posteriormente determinada su confiabilidad mediante un grupo piloto de estudiantes. El desarrollo del trab...

This research study was development by a research group which approached to determinate the index paper usage per student of the Universidad National Hermilio Valdizan during 2011, due to the lack of information about this issue and the importance such information due to its value as a environmental manage tool. For that development it was necessary to determinate a sample from the student population registered during 2011; the sampling resulted in a set of subsamples which were represent by the function of the quantity of students represented from every professional academic school in the academic headquarters of the university. To collect date it was use the survey which was validated by the research group and determinate its reliability through the pilot group of students. The development of this research establish that every student of the UNHEVAL use in average 951 sheets of paper B...

The goal of this research was to determine the índex of use of paper per student at Hermilio Valdizan National University in 2011, since there is no information about this and it is necessary to count with it, since it is importantto have with a tool forenvironmental management. Forthe development of this study a sample from the student population enrolled in the academic year 2011 was determined; sampling resulted in sub-samples that were formed on the basis of the number of students from each Academic Professional School of the main headquarters of the University. For the data collection, an instrument (survey) was used which was validated by the research group and subsequently determined its reliability through a pilot group of students. The development of the work allowed us to comply with the general objective, and as a result of this we have that each student at UNHEVAL uses on av...

El trabajo se realizó con el objetivo de conocer el comportamiento del parque automotor respecto a la emisión de algunos de los principales gases contaminantes, resultado de la combustión interna de sus motores, como el monóxido de carbono (co), la combinación de monóxido y dióxido de carbono (co+co2) y la presencia de hidrocarburos (hc) en los gases que emitían los vehículos y saber si sobrepasaban los límites máximos permisibles establecidos por el ministerio de transportes y comunicaciones. Se trabajó en los puntos y áreas de mayor densidad de tráfico vehicular previamente seleccionados. La metodología utilizada fue la descriptiva explicativa, mediante la técni ca de mues t reo; encontrándose que más del 66,7% de los automóviles emitían gases contaminantes por encima de los límites máximos permisibles, siendo los más críticos los fabricados antes de 1995 (85% f...

The research work entitled “MONITORING TIME DEVICE MANUFACTURING ONLINE PROCESS IN REAL TIME “, is an experimental research, within the category of quasi-experimental and is based on the construction of a prototype, conducted according to standards of University Management Research of the National University Hermilio Valdizán Huánuco.  The overall objective of the research was to develop a prototype of monitoring time device manufacturing online process in real time, it was achieved through the fulfillment of the specific objectives, being the first of them, determining the electronic devices that will let detect the beginning and end of workstations of fabrication process and transmit the information to a communications center, for which assessment was put through to different types of devices that based on features that were considered to be optimal for the purpose, the micr...

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...

Sentiment analysis is used to analyse customer sentiment by the process of using natural language processing, text analysis, and statistics. A good customer survey understands the sentiment of their customers—what, how and why they’re saying it. Sentiment dataset can be found mainly in tweets, comments and reviews. Sentiment Analysis understands emotions with the help of software, and it is playing an inevitable role in today’s workplaces. Sentiment analysis for opinion mining has become an emerging area where more research and innovations are done. Sentiment or opinion analysis based on a domain is done using several algorithms. Machine learning is a concept among this area. In this, the main focus is on the supervised sentiment analysis or opinion mining algorithms. Supervised learning is a division coming under machine learning. Different methods of supervised learning and senti...
