    El presente artículo propone un índice de satisfacción laboral utilizando el método de componentes principales. Para formar el índice se realiza la agregación directa de los primeros componentes principales, ponderados por la desviación estándar de cada uno. Este índice consigue cuantificar y resumir en un dato la satisfacción laboral de cada trabajador (a), expresándose en valores entre 0 y 100, lo cual facilita su interpretación y la toma de decisiones correspondientes. Adicionalmente, la metodología se aplicó a una base de datos con información de satisfacción labora

    AbstractA common and known problem among students on higher education (in general throughout the scholar life) is the difficulty of learning math. Nowadays the teaching methods for learning math remain relatively the same. Though, with the emerging of new technologies like portable devices (smart phones and tablets) and movement interaction devices (Nintendo WiiMote, Microsoft Kinect and PlayStation Move), learners and teachers have big interest on new ways of interacting through the teaching-learning process. In this sense the Natural User Interactions (NUIs) offer a great potential to facilitate new ways of computer enhanced learning, these have the potential to enhance classroom interactions, by increasing learners participation, facilitating the teachers’ presentations and creating opportunities for discussion. We present a system that combines gestural and touch interactions to support teaching math across multiple personal devices and public displays to enhance and support math education for college students. In a formative usability study, learners and teachers were positive about the interaction design and the learning possibilities for math education. Thus, this created good intentions in the users of continuing using it
