The assessment of welfare issues has been a challenge for poultry producers, and lately welfare standards needs to be reached in order to agree with international market demand. This research proposes the use of continuous behavior monitoring in order to contribute for assessing welfare. A software was developed using the language Clarium. The software managed the recording of data as well as the data searching in the database Firebird. Both software and the observational methodology were tested in a trial conducted inside an environmental chamber, using three genetics of broiler breeders. Behavioral pattern was recorded and correlated to ambient thermal and aerial variation. Monitoring video cameras were placed on the roof facing the used for registering the bird's behavior. From video camera images were recorded during the total period when the ambient was bright, and for analyzing the video images a sample of 15min observation in the morning and 15 min in the afternoon was used, adding up to 30 min daily observation. A specific model so-called behavior was developed inside the software for counting specific behavior and its frequency of occurrence, as well as its duration. Electronic identification was recorded for 24h period. Behavioral video recording images was related to the data recorded using electronic identification.. Statistical analysis of data allowed to identify behavioral differences related to the change in thermal environment, and ultimately indicating thermal stress and departure from welfare conditions.

The study aimed to examine the quality of interpersonal relationships developed between a child with cerebral palsy (CP) and his classmates during group play activities carried out in the classroom and during recess. The participants of the study were a boy with clinical diagnosis of quadriplegic CP, his teacher and classmates. Data collection was carried out by means of a structured interview with the teacher and of video recording the child with CP interacting with his classmates in play activities. The interview data analysis was carried out using qualitative procedures and the video recording was analyzed using a category system. The results showed that the teacher perceived the child with CP to be interested; he participated in play activities and interacted successfully both with familiar partners and with all classmates in general. On the other hand, the analysis of the video recorded activities showed that even though interaction did in fact occur positively, the child with CP remained mostly an observer of the activities rather than an active participant, possibly due to the gap between the child's possibilities and the requirements imposed by the activities underway in the school setting.

Purpose: To analyze the components of the acoustic signal of swallowing using a specific software. Methods: Fourteen healthy subjects ranging in age from 20 to 50 years (mean age 31±10 years), were evaluated. Data collection consisted on the simultaneous capture of the swallowing audio with a microphone and of the swallowing videofluoroscopic image. The bursts of the swallowing acoustic signal were identified and their duration and the interval between them were later analyzed using a specific software, which allowed the simultaneous analyses between the acoustic wave and the videofluoroscopic image. Results: Three burst components were identified in most of the swallows evaluated. The first burst presented mean time of 87.3 milliseconds (ms) for water and 78.2 for the substance. The second burst presented mean time of 112.9 ms for water and 85.5 for the pasty substance. The mean interval between first and second burst was 82.1 ms for water and 95.3 ms for the pasty consistency, and between second and third burst was 339.8 ms for water and 322.0 ms for the pasty consistency. Conclusion: The software allowed the visualization of three bursts during the swallowing of healthy individuals, and showed that the swallowing signal in normal subjects is highly variable.

A visual methods study was conducted with 16 at-risk youth living in a mid-sized Brazilian city. In this study, we focus on data obtained from four of those youth who were working adolescents, aged 13-15, and identify contextually specific protective processes associated with resilience. Through a reciprocal process of collaborative research that included observation, photo elicitation, video recording of a 'day in the life' of each youth, and semi-structured interviews, youth and researchers co-constructed an understanding of adaptive coping in a particularly challenging social environment. By employing techniques from grounded theory to analyze the data, we identified a pattern of protagonism among these youth that enabled them to maintain well-being despite exploitation as working children. This conceptualization of protagonism as a protective process has implications for human service workers who intervene to improve the living conditions of working children. © 2013 Taylor & Francis.

Esta pesquisa teve por objetivo observar, compreender e descrever a produção de sentidos mediante as interações dos alunos entre si, e destes com o professor ao desenvolverem projetos de modelagem matemática. A investigação foi realizada em uma turma de 5ª série de uma Escola de Ensino Fundamental e Médio da Rede Federal de Ensino na cidade de Belém do Pará. A observação participante foi à técnica predominantemente utilizada para a coleta de dados, que foram registrados através do diário de campo, de vídeos-gravações das aulas e áudios capitados nos grupos de alunos, quando desenvolviam as atividades propostas, constituindo assim a metodologia adotada. Desse modo, a pesquisa, de cunho qualitativo, se caracterizou como pesquisa-participante. O referencial teórico que subsidiou a pesquisa foi composto, predominantemente pela filosofia da matemática de Ludwig Wittgenstein, que entende o jogo de linguagem como uma forma de vida, ressaltando que a aplicação de regras e seus sentidos fazem parte desse jogo; o conceito de resíduo de Gilles-Gaston Granger, que se refere aos significados que estão além do texto matemático formal, ou seja, os aspectos que escaparam da malhas da rede lingüística; o conceito da educação matemática crítica, que se refere aos aspectos políticos da educação matemática e que traz para o debate, questões ligadas ao tema poder, que refletem nas interações entre os sujeitos no ato cognoscitivo, estabelecendo padrões de comunicação; além dos autores que tratam da modelagem matemática no ensino. As análises apontam para possibilidades de produção de ambientes de aprendizagem apropriados para transitar um padrão de comunicação que desempenhe sua função primordial em situação de ensinoaprendizagem: a comunicação através da linguagem ou dos jogos de linguagem.
