The search of the man for more comfort and one better quality of life led to an increment of the production of goods and services, that results, almost always, in aggressions to the nature and to a reduction of this same quality of life. The concern with the ambient problems appears as an important element regarding the material and economic growth and of the quality of life. With this scene a new question, the Ambient Marketing appears. Although the marketing concept to be well ample, the companies use the term ambient marketing to make reference what in fact, many times, are a more specific activity of ambient communication. The ambient communication is a new form to communicate used for the companies with the objective to get advantages of its competitors ahead, since the competitiveness by means of the o price, the stated period and the quality if becomes extremely incited. In view of the current competitive market, where the organizations need distinguishing to get greater have detached front to the competition, and the fact of the society to be each time more worried about the environment and the impacts that the companies cause it, the ambient communication has been used as form to convince its customers. Of this form, she evaluated herself, through a exploratory research and qualitative, the influence of the use of the ambient communication in the decision of purchase and of that she forms the companies when using of this communication can add value to its product. The results had indicated that 77% of the interviewed ones had heard to say on marketing or ambient communication and that the television is main the media for this knowledge, a time that 90.9% of the respondents had affirmed to have seen propagandas of directed products of consumption to the ambient question in this way. In fact, the concern with the environment demonstrated for the companies has its impact, therefore 84% of the respondents had told if to sensetize with this fact. However, only a lesser number of people, 70.5% answered that this concern really influences in its decision of purchase

This dissertation presents and discusses the results of an applied research on the accessibility of residents in a Long Term Care Institution (LTCIs) in the city of Natal- RN. The main objective of this research is to suggest projectual improvements that maximize the accessibility in a LTCIs of Natal-RN, considering the aspects of mobility, safety, comfort and independence of elderly residents. Moreover, one should consider the specific characteristics of the user population, capabilities and limitations of the biological process of aging, which causes damage to the neurological system, musculoskeletal and cardiovascular and progressively affects on visual acuity, balance and locomotion of elderly people. This research has a qualitative approach and divided into four phases: exploratory, bibliographical and documentary research, mapping of the LTCIs of Natal-RN, case study. The phase of the mapping presented an overview of accessibility on LTCIs of Natal-RN. The institution of the case study was defined based on the overall assessment of accessibility and ergonomics criteria, preceded by an application of an Ergonomic Work Analysis to understand the accessibility of the elderly people. Interactional and observational methods were used to collect field data. To this end, an intense process of social construction was conducted, involving the elderly residents, caregivers, health professionals and general servants and LTCIs´ managers. It was found that the NBR 9050 is not comprehensive to solve the diversity of accessibility problems found in LTCIs. All LTCIs investigated were in disconformity to the NBR 9050. In the case study, it was found that the inappropriate design hinders the daily activities of the elderly people and is a source of risk of accidents. The environment, facilities and lack of assistive technologies hinder the autonomy of the elderly people, and this LTCI requires ergonomic intervention to improve the accessibility, autonomy and security of the elderly people

The hotel industry is increasingly using the Internet like a management and operational tool. That way, the hotels will be more prepared to offer quality services to their guests and increase their profits as well. However, many managers seem don t perceive the advantages brought from this new digital environment. This thesis analyse the effects of the hotel managers perceptions as for the Internet effectiveness, Internet access, Internet as a communication tool, future importance of the Internet, benefits and drawbacks of the Internet, according to property type (simple, medium comfort and luxe), property size (quantity of the apartaments), age and hotel industry experience of the managers. The methodology utilized was a survey about the hotels that had at least 40 apartments (medium and big property size), were working in Natal-RN and classified in categories in the Guia Quatro Rodas Brasil, totalizing 35 hotels. Through the analysis of variance (ANOVA) and Tukey test, the results showed that the hotel managers with more than 50 apartments, the managers of the hotel more comfortable, the younger managers and the managers less experient in the hotel industry, demonstrated more conscious about the importance of the adoption of the Internet than the rest of the others. The contribution of this work is to offer more knowledge to the hotel executives about how they can use the Internet and show the importance of the web adoption in their properties

In the last decades there was a concentrate effort of researchers in the search for options to the problem of the continuity of city development and environmental preservation. The recycling and reuse of materials in industry have been considerate as the best option to sustainable development. One of the relevant aspects in this case refers to the rational use of electrical energy. At this point, the role of engineering is to conceive new processes and materials, with the objective of reducing energy consumption and maintaining, at the same time the benefits of the technology. In this context, the objective of the present research is to analyze quantitatively the thermal behavior of walls constructed with concrete blocks which composition aggregates the expanded polystyrene (EPS) reused in the shape of flakes and in the shape of a board, resulting in a “light concrete”. Experiments were conducted, systematically, with a wall (considerate as a standard) constructed with blocks of ordinary concrete; two walls constructed with blocks of light concrete, distinct by the proportion of EPS/sand; a wall of ceramic bricks (“eight holes” type) and a wall with ordinary blocks of cement, in a way to obtain a comparative analysis of the thermal behavior of the systems. Others tests conducted with the blocks were: stress analysis and thermal properties analysis (ρ, cp e k). Based on the results, it was possible to establish quantitative relationship between the concentration (density) of EPS in the constructive elements and the decreasing of the heat transfer rate, that also changes the others thermal properties of the material, as was proved. It was observed that the walls of light concrete presents better thermal behavior compared with the other two constructive systems world wide used. Based in the results of the investigation, there was shown the viability of the use of EPS as aggregate (raw material) in the composition of the concrete, with the objective of the fabrication of blocks to non-structural masonry that works as a thermal insulation in buildings. A direct consequence of this result is the possibility of reduction of the consume of the electrical energy used to climatization of buildings. Other aspect of the investigation that must be pointed was the reuse of the EPS as a raw material to civil construction, with a clear benefit to reducing of environmental problems

A housing unit was built to study the thermal performance, and of material using a composite made of gypsum and EPS ground. We used two techniques of construction, using blocks, and filling on the spot. Two compositions of the composite were studied. The blocks were fixed using conventional mortar. In the technical of filling on the spot were used PET bottles up inside the walls to provide mechanical and thermal resistance. Compression tests were realized according to the ABNT standard of sealing bricks. It is going to be shown an analysis of the thermal comfort through the use of thermocouples placed on the walls of the building, internally and externally. The manufacturing viability of houses, using recyclable materials, through the use of composite materials proposed will be demonstrated. The constructive aspects showing the advantages and disadvantages of the technique used also will be broached. The block used presents structural functions and thermal insulating, is low cost and represents an alternative to the use of EPS and PET bottles which are materials that end up occupying much space in the landfills, giving than an ecologically correct use. The results of thermal analysis shows the thermal comfort provided by the composite by the obtainment of a difference between the internal and external surfaces of the walls more exposed to the sun around 7º C. The average temperature of the air inside the building, around 28.0 º C was below the zone of thermal comfort recommended for countries with hot weather

We built an experimental house on an UFRN´s land using blocks made by a composite consisting of cement, plaster, EPS, crushed rubber and sand. Several blocks were made from various compositions and we made preliminary tests of mechanical and thermal resistance, choosing the most appropriate proportion. PET bottles were used inside the block to provide thermal resistance. In this work, a second function was given to the bottles: to serve as a docking between the blocks, because the ends of the cylinders came out of each block on top as well as at the bottom, with the bottom cut, allowing to fit of the extremities of the upper cylinder of a block in the lower holes of the other one, which were formed by the cutting already mentioned. Minimum compression tests were performed according to ABNT standards for walls closing blocks (fence). With that house built, we did studies of thermal performance in order to ascertain conditions of comfort, checking external and internal temperatures in the walls and in the ambient, among other variables, such as wind speed and relative humidity. The resulting blocks provided adequate thermal insulation to the environment, where the walls presented differences up to 11.7 ºC between the outer and inner faces, getting the maximum temperature inside the house around 31 °C, within the so-called thermal comfort zone for warm climates. At the end of the experiments it was evident the effectiveness of that construction in order to provide thermal comfort in the internal environment of the house, as well as we could confirm the viability of building houses from recyclable materials, reducing the constructive costs, becoming a suitable alternative for low- incoming families. Moreover, besides the low cost, the proposal represents an alternative use of various recyclable materials, therefore considered an ecological solution

This work proposes the development of an innovative material made from a vegetable polyurethane matrix and load of industrial waste, from retread tires, for thermal insulation and environmental comfort. Experimental procedures are presented, as well as the results of the thermal and acoustic performance of this composite material, made from an expansive foam derived from the castor seed oil and fiber of scrap tires. The residue was treated superficially with sodium hydroxide, to eliminate contaminants, and characterized macroscopically and microscopically. Samples were produced with addition of residues at levels of 5%, 10%, 15% and 20% by weight, for determination of thermal properties: conductivity, heat capacity and thermal diffusivity, sound absortion index and density. The results were compared to commercially available thermal insulation and sound absorbing products. According to the analysis of results, it was concluded that the developed composite presents characteristics that qualify it as a thermal insulation with superior performance, compared to commercial available insulation, and sound absorption capacity greater than the castor oil polyurethane s, without addition of the residue

Space Science was built using a composite made of plaster, EPS, shredded tires, cement and water. Studies were conducted to thermal and mechanical resistance. Inside the mold EPS plates were placed in order to obtain a higher thermal resistance on the wall constructed, as well as to give it an end environmentally friendly in view of both the tire and the EPS occupy a large space in landfills and year need to be degraded when released into the environment. Compression tests were performed according to ABNT blocks to seal, measurements of the temperature variation in the external and internal walls using a laser thermometer and check the temperature of the indoor environment using a thermocouple attached to a digital thermometer. The experiments demonstrated the heat provided by the composite values from the temperature difference between the internal and external surfaces on the walls, reaching levels of 12.4 ° C and room temperature in the interior space of the Science of 33.3 ° C, remaining within the zone thermal comfort for hot climate countries. It was also demonstrated the proper mechanical strength of such a composite for sealing walls. The proposed use of the composite can contribute to reducing the extreme housing shortage in our country, producing popular homes at low cost and with little time to work
