ABSTRACT
Radiology has demonstrated great utility for age estimation, but most of the studies are based on metrical and morphological methods in order to perform an identification profile. A simple image analysis-based method is presented, aimed to correlate the bony tissue ultrastructure with several variables obtained from the grey-level histogram (GLH) of computed tomography (CT) sagittal sections of the pubic symphysis surface and the pubic body, and relating them with age. The CT sample consisted of 169 hospital Digital Imaging and Communications in Medicine (DICOM) archives of known sex and age. The calculated multiple regression models showed a maximum R (2) of 0.533 for females and 0.726 for males, with a high intra- and inter-observer agreement. The method suggested is considered not only useful for performing an identification profile during virtopsy, but also for application in further studies in order to attach a quantitative correlation for tissue ultrastructure characteristics, without complex and expensive methods beyond image analysis.

Objetivo: O estudo analisou o perfil sociodemográfico e a percepção do trabalho de trabalhadores com e sem deficiência física do campus I da Universidade Federal da Paraíba- João Pessoa/ Paraíba/ Brasil. Material e Métodos:O estudo caracteriza-se como descritivo transversal, com26 trabalhadores, em dois grupos, 50% de Trabalhadores Com Deficiência Física (TCDF) e 50% de Trabalhadores SemDeficiência Física (TSDF). Utilizou-se o Questionário Sociodemográfico e percepção do trabalho (elaborado e adaptado pelo Método ANACT). Os dados foram analisados através da estatística descritiva, no programa estatístico SPSS versão 19.0. Resultados: Os dois grupos eram constituídos em sua maioria por mulheres, nos TCDF (53,8%)e TSDF (69,2%). Os TCDF apresentaram predomínio na faixa etária 50-59 anos (38,5%), diferente dos TSDF em que a faixa etária predominante foi 20-29 anos (53,8%). Na maioria casados, sendo nos TCDF (46,2%) e nos TSDF (53,8%); o nível de escolaridade como especialista nos TCDF foi de38,5% e nos TSDF 30,8%. Em relação à percepção no trabalho os TCDF (69,2%) e TSDF (53,8%) referiram em sua maioria o trabalho como importante; quanto ao final do dia de trabalho, os TCDF relataram predomínio na sensação de cansados (46,2%) enquanto que os TSDF disseram não possuir queixas (69,2%) ao final do dia de trabalho.Conclusão: Os resultados apontam que os TCDF valorizam mais o trabalho, apesar de referirem à sensação de desconforto (cansados), sugerindo a realização de estudos que promovam medidas de prevenção e a promoção de saúde destes trabalhadores.
Objective: This study examined the sociodemographic profile and work perception according to workers with and withoutphysical disabilities in the Federal University of Paraíba(Campus I), João Pessoa, Paraíba, Brazil. Material andMethods: This was a cross-sectional study with 26employees categorized into two groups, 50% of Workerswith Disabilities (WD) and 50% of Workers without Disabilities(WWD). We used the Sociodemographic and work perceptionquestionnaire (compiled by and adapted through the ANACTmethod). Data were analyzed using descriptive statistics onSPSS version 19.0. Results: Both groups were comprisedmostly of women: 53.8% (WD) and 69.2% (WWD). The WD predominated in the age group 50-59 years (38.5%), unlikethe WWD that were found predominantly in the group 20-29years (53.8%). The majority was married: 46.2% (WD) and53.8% (WWD); the education level as a specialist was 38.5%and 30.8% for the WD and WWD groups, respectively. As tothe work perception, most WD (69.2%) and WWD (53.8%)referred to work as being important; with regard to the endof the workday, WD reported tiredness (46,2%), while WWDhad no complaints (69.2%). Conclusion: The results suggestthat WD give more value to their work, although they refer toan uncomfortable feeling (tiredness), suggesting theconduction of further studies in order to provide these workers with preventive and health promotion measures.
