OBJECTIVE: To investigate the frequency of occurrence of short stature, overweight, abdominal obesity and arterial hypertension, and the possible correlations among such factors, in women of very low income. The findings were considered in terms of nutrition transition and the Barker's programming hypothesis. METHODS: A group of 223 women, 18 to 65 years of age, were studied with respect to the following parameters: for body mass index (kg/m2), values >25 indicated overweight and obesity, whilst values <18.5 indicated underweight; for waist/hip ratio, values >0.8 indicated abdominal adiposity; for systolic/diastolic blood pressure, values >140/90 mm Hg indicated hypertension; and for height, values within the 25th percentile (1st quartile) indicated short stature. RESULTS: The frequency of occurrence of overweight and obesity (present in 35.9% of the group) was greater than that of underweight (9.4% of the group). The diastolic blood pressure was positively associated with body mass index (r= 0.37; CI 95,0%: 0.01 <r2 <0.26) and with waist/hip ratio (r= 0.35; CI 95.0%: 0.01 <r2 <0.25). Subjects rated within the 1st and the 4th height quartiles, respectively, showed the following results: frequency of hypertension, 23.3% and 8.9% (odds ratio= 3.08; p= 0.03); frequency of overweight, 41.7% and 35.7% (p= 0.51); mean body mass index, 24.6 and 23.7 (p= 0.27); and mean waist/hip ratio, 0.87 and 0.85 (p= 0.04). CONCLUSION: Overweight and obesity were more prevalent within the group, than was underweight. Short stature, which is an indicator of malnutrition in early life, presents an important risk factor for both hypertension and abdominal adiposity in later life. The studied group appeared to be undergoing a process of nutritional transition, despite their low-income status. The mechanisms of metabolic adaptation to the malnutrition experienced in early life, might be important factors involved in any explanation of the results obtained in this research.

Clinical, epidemiological, and pathological aspects of trypanosomiasis caused by Trypanosoma vivax in calves were reported for the first time in northeast Brazil. Clinical and epidemiological data, packed cell volumes (PCV), and parasitemia were assessed in 150 calves in May 2009 (rainy season—survey 1) and in 153 calves in November 2009 (dry season—survey 2) in three farms (A, B, and C). Prevalence of T. vivax in calves examined in the survey 1 was 63.3%, 65.0%, and 80.0% in farms A, B, and C, respectively. Morbidity varied from 63.3% to 80%, mortality from 15% to 30% and lethality from 23% to 37.5%. In survey 1, for all farms, high parasitemia (from 30.3 to 26.2 × 106 parasites/mL), fever (from 39.8 to 40.3°C), low PCV (from 15.7% to 18.1%), and body score (from 2.5 to 3.5) were detected. Calves showed depression, weight loss, pale mucous membranes, enlarged lymph nodes, edema of the dewlap, cough, coryza, and diarrhea. The animals from farms A and B were treated with diminazene aceturate. Six months after, in survey 2, non-treated calves from farm C showed values for prevalence (81.82), morbidity (81.82), mortality (12.73), and lethality (15.55) similar to those in survey 1 (P > 0.05). Also in survey 2, four calves aging merely 1–3 days old presented high parasitemia levels (from 32 × 106 to 74 × 106 parasites/mL), suggesting transplacental transmission. In conclusion, trypanosomiasis by T. vivax constitutes high prevalent disease for calves raised in Brazilian semiarid and may have transplacental transmission.

Necroscopic examination is remarkably useful to diagnose wild animal's diseases. In several occasions the clinical signs are not charactheristic as in domestic animals and the occurrence of death in asymptomatic animals is frequent. Thus, the present work aimed to accomplish a retrospective study on agouti diseases diagnosed by pathological examination in the Laboratory of Veterinary Pathology, Federal Rural University of the Semi-arid, through January 2006 to December 2006. In 32 agoutis submitted to the necropsy, the percentage of diagnosed diseases was: perinatal death due hypothermia/ inanition complex (21.6%), obstructive urolithiasis (6.24%), dystocia (6.24%), cecum sablosis (6.24%), intussusceptions (3.20%), fecaloma (3.20%) and esophagus obstruction (3.20%). A total of 16 (50.08%) animals remained undiagnosed in which nine (28.48%) showed advanced autolysis and seven (21.60%) agouti had none macroscopic or microscopic lesions compatible with any disease. The present article presents reports of some diseases not yet diagnosed in agoutis and these results may produce literature review about the pathologic aspects of these diseases in this species.

Visando analisar como as pequenas empresas aracajuanas relacionam-se com seus clientes no Facebook, foi realizado um estudo de casos múltiplos comparando empresas que oferecem seus serviços exclusivamente pela Internet – denominadas empresas Virtuais - e empresas que o fazem apenas presencialmente – denominadas empresas Físicas. Dentre os resultados, percebeu-se que apenas as empresas Virtuais mensuram o retorno sobre o investimento no Facebook e apenas este grupo demonstrou interagir diretamente com o cliente, o que denota uma baixa convergência das empresas Físicas em termos de propósito e uso dessa rede social para o relacionamento com o cliente.

Resíduos de produtos farmacêuticos, para humanos e animais, mensurados em milhões de toneladas por ano, são descartados inadequadamente, indo parar em sistemas aquáticos e no solo. A literatura mostra que, apesar da preocupação e alguns escassos estudos que apontam para este perigo, a maioria dos países-inclusive o Brasil-não têm uma política ou legislação específica para este problema. Entre as propostas veiculadas se inclui a logística reversa, que devolveria sobras e produtos vencidos ao seu ponto de origem. Neste estudo discute-se não somente o descarte inadequado de fármacos, mas também o sistema de gerenciamento de armazém dentro do qual se enquadra a logística reversa, apontada como um dos remédios viáveis para a mitigação do problema. Por meio de um estudo de caso de natureza qualitativa, num grande distribuidor de medicamentos, os resultados apontam no sentido de que as tecnologias de gerenciamento de armazéns facilitam, mas não solucionam o problema como um todo. São ainda apontadas pesquisas futuras.

—Context. Considering the importance of software testing to the development of high quality and reliable software systems, this paper aims to investigate how can work-related factors influence the motivation of software testers. Method. We applied a questionnaire that was developed using a previous theory of motivation and satisfaction of software engineers to conduct a survey-based study to explore and understand how professional software testers perceive and value work-related factors that could influence their motivation at work. Results. With a sample of 80 software testers we observed that software testers are strongly motivated by variety of work, creative tasks, recognition for their work, and activities that allow them to acquire new knowledge, but in general the social impact of this activity has low influence on their motivation. Conclusion. This study discusses the difference of opinions among software testers, regarding work-related factors that could impact their motivation, which can be relevant for managers and leaders in software engineering practice.

RESUMO A expansão dos cursos de Educação à Distância (EaD) tem como base o discurso de que ela democratiza a educação, pois chega a lugares nos quais o ensino tradicional não consegue alcançar. Seu alcance se deve, sobretudo, às tecnologias da informação, como a Internet, que são fundamentais para à veiculação da educação à uma diversidade de grupos sociais. Neste contexto, o Ambiente Virtual de Aprendizagem (AVA) desempenha um importante papel para atender a todos. Com isso, o acesso à informação em um AVA deve contemplar diferentes usuários, incluindo os usuários (pessoas) cegas. Tendo como finalidade verificar se os AVAs são acessíveis a esse grupo, realizou-se uma pesquisa de caráter avaliativo, misto e exploratório, numa concepção pragmática, com a participação de usuários cegos, bem como com validadores automáticos para identificar possíveis problemas de acessibilidade. Entre os resultados, verificou-se que o AVA analisado tem aspectos positivos da acessibilidade, mas necessita de ajustes para ser considerado totalmente acessível. ABSTRACT The Brazilian institutional program called Distance Education (EaD) integrates the federal and state policy project whose objective is to expand and to introduce higher education to all interior places in Brazil. Its range is mainly due to information technologies such as the Internet, which are fundamental to the educational placement to a variety of social groups. In this context, the virtual learning environment (VLE) plays an important role for suit everybody. With this, the access to information on its VLE should contemplate different users including the blind people. In order to check if the VLE is accessible to this group, there were mixed methods research and exploratory with the participation of blind people, as well as automatic validators to identify potential accessibility problems. Among the results, it was found that the VLE has positive aspects of accessibility, but needs tweaking to be considered fully accessible.
