Abstract—: This study presents the results of ultraviolet radiation measurement in a truncated compound parabolic concentrator. The measurements were performed by using of a portable ultraviolet sensor both inside and outside the concentrator without the presence of receiver, under direct and diffuse solar radiation, to calculate the real value of the concentration factor of ultraviolet radiation. The truncated compound parabolic concentrator was designed in Solid Works and built via 3D printing, with a theoretical concentration factor of 4.6. This study showed the differences in the form of the ultraviolet radiation when measurements were made under direct radiation and diffuse solar radiation. These differences are important when measurements were made along the concentrator profile, at different heights within the concentrator and, also, along it. Finally, a concentration factor of ...

To determine the level of satisfaction in restaurants of Miraflores city and the relationship between customers satisfaction and the the working environment this study was done. 150 restaurant workers and 150 consumers were surveyed. Data were collected and processed using logistic regression technique.The most outstanding result was the high level of satisfaction shown by both the internal and the external clients and the statistically significative relationship between the satusfaction level of workers with customers
