Estudo preliminar da preferência de cor para rota e seta de manobra em mapas de sistemas de guia de rota

In-Car Navigation System and Route Guidance (RGNS), commercial or free, have adopted different graphic designs to maps which support the navigation task. This paper aims at evaluating the driver's subjective preference for colors to represent route and arrow direction in maps for these systems. A total of 54 drivers (27 males and 27 females) participated in an experiment which was performed in a parked vehicle. Two cartographic representations were produced to evaluate the route color and other two for the arrow color. The route was symbolized by black or blue color and the arrow direction by green or red hue. The cartographic representations were presented in a seven-inch navigation monitor. The results indicate that most drivers prefer the navigation route in black color. However, drivers who regularly use navigation systems have presented the tendency to prefer the route in blue hue. The direction arrow in green hue was the mostly preferred by the drivers and there was no significant correlation between different individual characteristics. This study concludes that drivers' preference was influenced by different factors, such as grouping by color, shape and proximity, subjective or conventional association, as well as by the level of contrast among the map features. Evaluating the performance of cartographic representations in route following task is recommended, in order to support the influence of graphic designs to maps in usability of route guidance systems.

Por trás da qualidade: inter-relações das Relações Públicas e os sistemas de gestão de qualidade

This study examines some characteristics of the contemporary reality and its influence on the dynamics of the organizational activities, in particular, related to the quality management. Discusses capitalist logic of maximization of profits that has been sophisticated in face of new scenarios that arise with society evolution. It also proposes a reflection on the philosophies and formats of management that fits with the desire to meet the needs of society through the expansion of quality - now a reference for the production processes and management systems. The work highlights the relations between communication and quality, pointing them as fundamental to the use of fissures on the evolution of the capitalist system in developing programs, philosophies and management systems. The intention is to turn able ways to contemplate the needs and interests of the largest number of public and variables in a different relation than the usual, in which a few wins and many lose

Correspondência de cor de diferentes marcas e sistemas de resina c omposta em relação à escala vita classical

The objective of this study was to compare different resins and determine their matching color with Vita shade, also investigating the possibility of substitution among them and the correlation between the visual and spectrophotometry methods of color selection. The composite resin Tetric N-Ceram® shade A1 was used as light-control and color A4 as dark-control. For each material were prepared five 10 x 2 mm disks. Analyses were performed in a metamerism box by volunteers who ordered the specimens from the lightest to the darkest. The spectrophotometry was carried out using the spectrophotometer Vita Easyshade®. ∆E values were subjected to analysis of variance with 5% significance level. The Fisher exact test showed that there was no color match among the materials and the reference Vita shade. The possibility of substitution among the composites could not be established. The two methods are able to correctly differentiate the control resin A4 as distinct from the other resins shade A2.

Avaliação das causas e consequências das patologias dos sistemas impermeabilizantes: um estudo de caso

This work aims to assess a case ofwaterproofing pathology, from the presentation of the pathological manifestations, thecharacterization and quantification of negotiationsproposals. With these data, graphs were elaborated with thepurpose ofemphasizing the cost increase from the time of intervention, to give an increase of 1,429.00 % inthe presented study. Also show the proportion of spending on finishes and waterproofing,demonstratingthe greatinfluence of the finishes in the composition of the treatment costs. Inthisstudy, it was foundthat these finishes made up89% of the total cost. In the bibliographic reference, presented to the active mechanisms, the characterization of waterproofing systems and the most common pathologies. It follows the importance of sealing to ensure integrity of a construction
