An effective warning attracts attention, elicits knowledge, and enables compliance behavior. Game mechanics, which are directly linked to human desires, stand out as training, evaluation, and improvement tools. Immersive virtual reality (VR) facilitates training without risk to participants, evaluates the impact of an incorrect action/decision, and creates a smart training environment.

In that sense, this paper presents two main aims developed: the improvement of a virtual navigation system through the results of previous user studies and mixed research (quantitative and qualitative) improved based on the user perception for educational and professional uses. The VR system used is based on Unreal Engine programming of the HTC Vive sensor.

Method: A systematic review of the literature of the past decade on the role of vitamin B12 in bone mineral density and fracture risk in subjects of all ages and both sexes was performed by means of a PubMed, Science Direct, Medline and SciELO database search. Articles included in this review were identified using the search terms: B12 Vitamin and Bone Mineral Density and Vitamin B12 and Risk of Fractures.
This paper presents the results of a research carried out in the states of Pernambuco and Rio Grande do Sul, Brazil about differences and similarities in the graphic representation of safety signs at factories of food, steel, shoes and construction/ building industries, together with their workers' opinions on the security signs. The overall results show differences in the sign structure across the states, confirming the influence of cultural differences on the design of safety signs, which must be taken into account during the design process.

Objective: To determine the profile of such glomerulopathies in a public hospital located in the city of Brasilia, Federal District.
Methods: 121 renal biopsies in different patients were performed by the Renal Division of Hospital Regional da Asa Norte (HRAN) between August 2005 and May 2009.
Introduction: The objective of the study is to identify the main risk factors for death by New World visceral leishmaniasis and establish a coherent pathogenic substrate of severe disease based on clinical findings.
Methods: Seventy-six deceased inpatients and 320 successfully treated inpatients with VL were studied in a case control study.
Results: Bacterial infection and bleeding were mutually exclusive events leading to death.
A new role for the plant growth-promoting nitrogen-fixing endophytic bacteria Gluconacetobacter diazotrophicus has been identified and characterized while it is involved in the sugarcane-Xanthomonas albilineans pathogenic interactions. Living G.diazotrophicus possess and/or produce elicitor molecules which activate the sugarcane defense response resulting in the plant resistance to X.
