Varasquim, Francisco Mateus Faria de Almeida;Alves, Manoel Cléber de Sampaio;Gon?alves, Marcos Tadeu Tiburcio;Santiago, Luis Fernando Frezzatti;Souza, Alexandre Jorge Duarte de;
CERNE , 2012, DOI: 10.1590/S0104-77602012000200007
Abstract: the sanding process is important to the quality of wood products. sanding reduces imperfections in wood surfaces and it is important to the final product and application of paints or varnishes. there are few studies about sanding in the literature and finding out the relationship between the input parameters (i.e., species of wood, grit size, abrasive) on the output parameters (i.e., roughness, force, pressure) will help to improve this process. this study analyzed the influence of input parameters as belt speed (cutting speed), grit size and pressure on the output parameters as surface roughness, cutting force (sanding force) and power consumption on cross-grain sanding of eucalyptus grandis wood. the tests were performed with 3 types of grit sizes (80, 100 and 120 grit), 3 belt speeds (10, 11 and 12 m/s) and 2 pressures (219.89 and 283.44 g/cm2). the surface roughness was analyzed based on roughness average (ra). sanding efforts were analyzed by cutting force and power consumption. it was found that the 100 grit size provided the lowest cutting force. it was observed that the belt speed, pressure and grit size influenced the surface roughness, cutting force and power consumption. the best surface finishes were obtained in tests with higher pressure.

Revista de Saúde Pública , 2008, DOI: 10.1590/S0034-89102008000400021
Abstract: objective: to describe factors associated to inequalities in access to health care services and utilization for the elderly. methods: study part of the health, well-being and aging in latin america and the caribbean ("sabe") survey that included 2,143 elderly individuals aged 60 or older in the city of s?o paulo, southeastern brazil, in 2000. a two-step sampling procedure with probability proportional to size was carried out using census tracts with replacement. to achieve the desired number of respondents aged 75 or older, additional households close to the selected census tracts were sampled. access to health services and utilization were measured for outpatient and hospital services during a 4-month period prior to the interview, and correlated to factors related to ability, need and predisposition (total income, schooling, health insurance, reported medical condition, self-perception, gender and age).multivariate logistic regression was performed in the analysis. results: of all respondents, 4.7% reported being hospitalized and 64.4% seeking outpatient care in the four months prior to the study. as for public outpatient care provided, 24.7% were in hospital clinics and 24.1% in other public outpatient services. as for private care, 14.5% received care in hospitals and 33.7% in health clinics. the multivariate analysis showed an association between health service utilization and sex, medical condition, self-perceived health, income, schooling, and health insurance. however, an inverse effect was found for the variable "schooling". conclusions: the study results show inequalities in access to health services and utilization as well as a deficient health care system. public policies should take into account the specific needs of the elderly population to facilitate access to health care services and reduce inequalities.
Cidade/município saudável - a quest?o estratégica: o compromisso político
Almeida, Eurivaldo Sampaio de;
Saúde e Sociedade , 1997, DOI: 10.1590/S0104-12901997000200009
Abstract: the proposal of healthy cities is analyzed in the strategic perspective and political commitment. issues like the meaning of the expression, its identity, nature, inclusion, motivation and its implications to public policies are posed for reflection. its understanding as both strategic issue and of political commitment is adopted to prevent it from being understood and adopted just as a technical, parallel and marginal project in the planning and administration of the public policies and/or as an isolated moviment or "fashion". thus it was, in the view of the author, understood and inserted, as an articulated movement in contact with other social movements. in this context it was analyzed as a permanent process of political commitment or of potencialization of public policies with efficiency and effectiveness, from and for change of social realities of cities/municipalities, in the sense of progressive and substantive improvement of the quality of life of its populations.
Um modelo de retorno sobre investimento em a??es promocionais n?o monetárias
Prado,Guilherme de Almeida; Prado,Karen Perrotta;
Revista Portuguesa e Brasileira de Gest?o , 2009,
Abstract: sales promotion has been growing in importance in the marketing mix. also, measuring return on marketing investment is becoming more relevant. furthermore, sales promotion academic studies found in the literature are concentrated in monetary promotions (deals, coupons, rebates) and there are few studies in non-monetary promotions. the objective of this paper is to develop a model of evaluating the return on investment on non-monetary promotions that could be easily implemented. so, a literature research was carried out, especially in sales promotion and return on marketing investment. afterwards, a conceptual model of return on investment on non-monetary promotions was developed, which allows to obtain the financial return on a promotional activity and to verify improvements in brand perception. despite the conceptual model, it is detailed the way the model must be implemented and two practical tests were conducted to verify its limitations and failures.
