The aim of this paper is people recognition based on their gait. The authors propose a computer vision approach applied to video sequences extracting global features of human motion. From the skeleton, the authors extract the information about human joints. From the silhouette and the authors get the boundary features of the human body. The binary and gray-level-images contain different aspects about the human motion. This work proposes to recover the global information of the human body based on four segmented image models and applies a fusion model to improve classification. The authors consider frames as elements of distinct classes of video sequences and the sequences themselves as classes in a database. The classification rates obtained separately from four image sequences are then merged together by a fusion technique. The results were then compared with other techniques for gait recognition.

There is no consensus among the studies regarding the association between behavior problems and worse outcomes in alarm treatment for enuresis. The aim of this study was to investigate the relationship between behavior problems and outcome in alarm treatment for primary enuresis with weekly sessions with a therapist. The participants were 20 children with primary enuresis, 13 boys and 7 girls, between the ages of six and ten. Half of these children presented clinical scores on the Child Behavior Checklist. Eight out of the 10 children without behavior problems who finished the treatment have achieved the criteria for initial success (14 consecutive dry nights) and two of them dropped out. Only half of the children with behavior problems attained initial success, four of them dropped out and one finished without success. These differences on the outcome were not statistically significant. There were also not found significant statistical differences in the occurrence of relapses rates between children with and without behavior problems. Four of the eight children without behavior problems who attained initial success have relapsed, and four have maintained the acquired nocturnal control. Three of the five children with behavior problems who achieved the initial success have relapsed and two of them satisfied the criteria for continued success. The only statistical difference found between the children groups was the time required to achieve initial success. In 12 weeks of treatment, the probability of attaining initial success was 86.11% for children without behavior problems and 10% for children with behavior problems; in 20 weeks, the probability was 100% for children without behavior problems, and 40% for the children with behavior problems. Therefore, it is possible to say that in that sample of children the behavior problems seemed to provide difficulties in achieving progresses in the alarm treatment for enuresis. On most of the cases, those difficulties were not enough to make the outcomes at the end of the treatment of children with behavior problems being statistically different from the children without behavior problems. These results suggest that children with behavior problems may benefit from alarm treatment as well as children without behavior problems. Considering the time required for achieving success, the results indicate that they probably need more intensive support during enuresis treatment with alarm than children without other problems.

Arantes ae RESUMO. O presente estudo comparou adolescentes infratores e não-infratores com relação a dois aspectos: grau de adversidade familiar e grau de concordância entre a autopercepção e a percepção dos pais sobre problemas de comportamento dos jovens. Participaram deste estudo 40 adolescentes, 23 atendidos no Centro de Atenção e Apoio ao Adolescente (UNIFESP) e 17 adolescentes considerados infratores sob intervenção da Vara da Infância e da Juventude da comarca de Santos. Os instrumentos utilizados foram o Child Behavior Checklist (CBCL), Youth Self Report (YSR) e o Índice de Adversidade Familiar de Rutter. O Índice de Adversidade Familiar do grupo de adolescentes infratores foi significativamente maior. Os resultados apontaram ainda que, embora a diferença não tenha sido estatisticamente significante, a porcentagem dos escores de discordância nas percepções sobre problemas de comportamento foi maior entre os adolescentes infratores e seus pais.

O objetivo do estudo foi investigar o efeito do tratamento para enurese sobre os escores de outros problemas de comportamento. Foram coletadas as informações de 97 prontuários de crianças e adolescentes atendidos no período de 2002 a 2006 em uma clínica-escola de psicologia, em programa específico para enurese com uso do alarme de urina. Os dados sobre problemas de comportamento foram avaliados por meio do Child Behavior Checklist, respondido pelas mães antes e depois do tratamento. Foi encontrada uma redução significativa nos escores de problemas de comportamento, independentemente do sucesso ou não no tratamento para enurese.
