Objective: The aim of this study was to evaluate the sleep quality of medical students to identify the main factors that affect sleep patterns. Methods: According to the methodology, 154 students participated in the research, attending from the first to the sixth year of the course. The Pittsburg Sleep Quality Index questionnaire and the Epworth sleepiness scale were applied. descriptive statistics techniques were applied and demonstrated in the form of tables and graphs. The comparison of variables was carried out using statistical tests. results: The results showed that most students do not sleep very well. It was observed that 68.83% of a total of 106 students are bad sleepers. Conclusion: It is concluded that medical students sleep a low number of hours by period, which could interfere in impairment of attention, learning and memory formation, interfering in academic performance. On the other hand, they showed greater daytime sleepiness compared to the general population.

Mobbing behavior is an important and widespread antipredatory behavior. This is a well-known behavior especially in birds. There are many studies about mobbing in birds, and most of them use owls as a model of predator. However it is not clear how mobbing works when a predator assume a role of a prey. In this paper we organize field observations, which were taken on records of mobbing behaviors performed by owls or by other animals against them. These observations were collected nearby four Brazilian cities in South-Eastern and Central Brazil： Joao Monlevade / MG, Sacramento / MG Baguari / MG and Cacu / go. Events of mobbing behavior have always involved prey（s） and predator（s） thus, in this study we presents mobbing events which species of owl always were involved, and beside the owls, other animals like mammals or raptors. These records are important due to their infrequency and problems to be detected in natural field conditions. It is rare mobbing events when an owl assumes a role of a prey, and there are few studies that show the mobbing by the predator optics. The present data may contribute for elucidation of mobbing behavior intrinsic aspects.
