Ergonomics, the science of working rationalization, seeks the best relationship between man and his working tools. In Dentistry, ergonomics is present as for the professional working correctly seated, in functional comfort, intervening of supine position patient, by means of suitable equipment and instrument. Nowadays, dental equipment is justly rationalized; however, some instruments should take shape, in order to adapt those requirements. The hand tool design should permit a comfortable, non-slip and safe handling. Thus, anatomical details, the correct position of the operator for its use and specific characteristics of application should be taken into account. The instrument under analysis - forceps - was conceived according to these requirements along with a new alveolar tooth extraction technique, based on electromyographic and biomechanical studies. The morphology of the instrument, which makes possible a simple and natural kinetics of the operator, was obtained by changing the paradigm of the conventional cross-action instruments (whose grip is always on the arms of the tool), divesting the handle from the tool arm. This induced on anatomical conceiving of perpendicular handles to the extremity of the tool arm, resulting an efficient and effective instrument, according to indicated on its experimental phase

This study consists in the observation and evaluation of the thermal behavior and distribution of wood composite walls, MDF – Medium Density Fiberboard, HDF – High Density Fiberboard, OSB – Oriented Strand Board and EGP – Edge Glued Panel. This study had the objective to present the experimental thermal behavior and to verify which one fit the thermal comfort standards for human labor For this work, was developed a thermal chamber, with one interchangeable side, so the wall prototypes would fit for each experiment. We studied walls made of MDF, HDF, OSB and EGP, which one had its own distinct behavior due to the panel construction. The EGP wall had shown the most reliable material for this usage at high temperatures. With this work, it was demonstrated the importance of choice for the right material and construction method for wooden composite walls, because if they were scaled poorly, the people exposed to them would be uncomfortable by the proportionate environment, and the costs for a resizing would be too high

The discussions about the energy rationalization are gaining more and more space on the everyday of engineers and other professionals in the field of energy. A greater focus is being tied to commercial buildings, because they are one of the biggest responsible for the high energetic expenditure according to the National Energetic Balance, especially by the use of air conditioners for the people’s thermal comfort. Such finding made INMETRO to develop a building labeling procedure through th National Program of Electric Energy Conservation in Buildings; by means of this systematic, the built areas are classified by levels that go from A(the best) to E(the worst), taking into account envelopment, illumination system and air conditioning. A bonus process based on water rationalization, use of renewable energy sources, cogeneration systems or technical innovations, allows the classification to be changed up to one level. A study made exactly on a commercial building, the building of Foundation for Technological and Scientific Development located inside of the College of Engineering of Guaratinguetá, sought to identify technical/economic alternatives for the building certification and appealed to the bonus based on water rationalization. The present study is based on analysis of deploying a cogeneration system formed by internal combustion engine and an absorption refrigeration system as bonus alternative, so that the costs are analyzed regarding energy consumption and use of the motor. With the calculations and results, the viability of the building to receive a bonus from INMETRO through its National Program for Energy Conservation in Buildings is studied and concluded from this study whether or not you can get a better level of energy efficiency for the building in question...

GOALS: This research evaluated the change in arterial pressure before and after two procedures of dental prophylaxis: Jet system baking soda and conventional prophylaxis and patient's opinion regarding the comfort of each one. MATERIAL AND METHOD: Were selected 32 patients with age between 18 to 30 years old, who need prophylaxis to remove biofilm and were subjected to three different types of treatment: sodium bicarbonate jet (G1), prophylaxis conventional (G2) and placebo (G3) at intervals of one month between them. Patients were divided randomly. Arterial pressure was measured by wrist digital Omron HEM – 6111. The measurements were realized in four times: before the prophylaxis, immediately the end of procedure, 15 and 30 minutes after finished of treatment. Patient comfort was measured by a Visual Analog Scale (VAS) after the end of the treatment. The data were analyzed using the variance test. The results showed that there was statistically significant difference to the comfort of the procedures. RESULTS: There was a statistically significant difference to the comfort of the procedures, and G2 and G3 better than G1. Regarding the variation of arterial pressure there was no statistically significant difference between groups. CONCLUSIONS: The methods of prophylaxis no effect on arterial pressure, but conventional prophylaxis is more comfortable than others treatments

This work deals with the thermal load study of a fictitious aircraft as well as scaling, in terms of the airflow and temperature of the air conditioning system, for heating and cooling of the its internal environment, aiming the thermal comfort of occupants. The first part is presented the techniques and methods utilized for modeling different heat exchanges that occur in the aircraft and then allowed to calculate the total heat load and the airflow and temperature necessary to comply with the requirements of the thermal comfort. Techniques to determine the basic parameters, as convection coefficient and global coefficient of heat exchange, are also presented. The work aims to develop a program, using a computational tool, to automate the calculations so that facilitate this study. It also allows to be used for other airplanes just changing parameters and the control variables related to the specific project. Finally the program performs calculations for a fictitious airplane, to analyze its functionality and the influence of parameters involved in the temperature controls. The program allowed analyzing the sensitivity of portions of the thermal load and the corresponding parameters of influence, as well as the scaling of the air conditioning in terms of airflow and temperature. It was considered, despite the simplifications, a good approximation to the actual values and then can be used in development of the other airplanes

This research aimed to analyze the spatial area for the design of the Heat Island of Subprefecture Sé, in São Paulo-SP, with the support of geotecnology and based on the study of environmental perception. We used remote sensing products such as maps ofland use and soil temperature and apparent surface to evaluate the thermal conditions considered critical points in the central area of the municipality. The methodology used was qualitative analysis, based on interviews with the people, allowing rescue geoecology the conditioning aspects of the city, with an emphasis on environmental perception. This study aimed toanalyze the perception of the variation of the thermal field in São Paulo. The results indicated that (95%) of respondents feel that the temperature of the central area has increased each year, and the district that stood out was the Sé, due to intense use and occupation of land and contribute one of the largest shopping centers. Districts with points given for having better thermal comfort were Santa Cecília, the República and Bela Vista, due to their larger amount of green areas by fiscal court, which act as local refrigerators. It was found that the respondents have the perception and awareness of their spa directly related to the quality of life. Through analysis of several variables involved, proposals and strategies may support public policies and urban planning

The study and selection of an equipment of air conditioner for any type of environment, should be made without overestimate or undersizing the project. The undersizing does not provide an adequate comfort temperature if the environment is too hot because the air conditioner does not remove all the heat necessary in the environment. But if the project is oversized, energy consumption is higher and there is an unnecessary cost. To prevent these failures is necessary to make a calculation of the thermal load on the environment and choose the equipment that has a higher cooling capacity than the calculated heat load and closer to the calculated heat load. In this graduate work will be chosen an air-conditioned equipment for bus, showing the calculations made for the thermal load for various types of heat gain in this type of vehicle. The thermal load on vehicles is more complicated to calculate than in areas because there are several factors that vary with the movement of the vehicle. It will also explain the compression refrigeration cycle, which is the cooling system used in vehicles because it is weightless, compact and lower cost. From the calculated heat load, it will be chosen an air conditioner that best suits the project and, finally, a brief presentation of the selected equipment will be made

This is study proposes to evaluate the ergonomic aspects of dental equipments. Based on the characteristics proposed by ISO/FDI, on the existing literature and related researches an evaluating system was devised. Thirty nine dental clinics were examined using the 165 pointssystem proposed, distributed in 12 criteria. None of the dental clinics examined showed a bad ergonomics level, 41% were good and 59% reached excellent levels. The point-supported evaluation system proposed is effective in the analysis of the ergonomic conditions of dental equipments, allowing a quantification of their characteristics. Using this system, the dentist can also know the level of ergonomic satisfaction existing in his equipment, and identify the conditions to be improved. It was concluded that the equipment belonging to dental workplaces evaluated had excellent level of compliance, however corrective measures are needed since even the presence of a few non-conforming items is a sufficient condition to cause injury to users, decreased efficiency and comfort and loss quality of service
