Abordaje práctico sobre cómo mejorar el bienestar en los bovinos

Current challenges of humanity require a new paradigm for animal production, and invest time and attention to the development of new production techniques that take into account the principles of sustainability and animal welfare science. To do this, we must be committed to promoting animal welfare and health, ensure environmental sustainability, consumer satisfaction and profitability for producers. To change our relationship with animals there is no need for changes in market conditions or large investments, it is enough to know better the needs of the animals we raise, the management system adapted to its characteristics. Even in the most favorable management conditions, on farms that have technological resources and trained personnel, there is much to change, especially in the daily management of the animals. Some of the risks more evident in the traditional systems of beef production are: problems during parturition, morbidity and mortality of calves, lack of shade in the pastures, improper handling of animals, risk of injury, inadequate infrastructure, poor management practices during routine processing (marking, castration, vaccination, dehorning), poor welfare during loading, transport, unloading and slaughter. To remedy this, you can adopt good management practices, which have been shown to reduce risk and improve the welfare of cattle in different stages of the production chain. The objective of this review is to show some of the risks that reduce the welfare of cattle and examples of how the adoption of best management practices impact on improving the productivity of these production systems. Finally, some indicators for assessing welfare in production systems are shown.

Sleep complaints and polysomnographic findings: A study of nuclear power plant shift workers

The literature widely recognizes that shift workers have more health complaints than the general population. The objective of this study was to describe the prevalence of sleep complaints and verify the polysomnographic (PSG) variables of shift workers in two Brazilian nuclear power plants. We carried out a subjective evaluation with a sleep questionnaire. Based on these results, the interviewees that reported sleep-related complaints were referred for polysomnographic evaluation. of the 327 volunteers initially evaluated by the sleep questionnaire, 113 (35%) reported sleep complaints; they were significantly older, had higher body mass index (BMI), and worked more years on shifts than those without sleep complaints. of these 113, 90 met criteria for various sleep disorders: 30 (9%) showed obstructive sleep apnea (OSA), 18 (5.5%) showed limb movement, and 42 (13%) evidenced both sleep problems and had a significantly higher proportion of sleep stage 1 and arousals compared with the 23 shift workers that had no indices of sleep problems. The present study found that 90 (27.5%) of the evaluated participants met the PSG criteria of some type of clinical sleep disorder. This high proportion should be investigated for associations with other aspects of work, such as working hours, working schedule, years performing shift work, and access to health services. Due to the strong association between sleep disorders and the incidence of fatigue and sleepiness, the evaluation of the sleep patterns and complaints of shift workers is essential and should be considered to be one of the basic strategies of industry to prevent accidents.

Inibidor da ação do etileno na conservação pós-colheita de Chrysanthemum morifolium Ramat cv. Dragon

A durabilidade e a qualidade pós-colheita de flores de corte são atributos fundamentais na sua valoração ao longo da cadeia produtiva e na satisfação dos consumidores. Objetivou-se, nesta pesquisa, verificar o efeito do tiossulfato de prata, associado ou não à sacarose, na manutenção da qualidade pós-colheita de hastes de crisântemos (Chrysanthemum morifolium Ramat cv. Dragon) . O experimento foi conduzido sob delineamento inteiramente casualizado, em esquema fatorial testando soluções de manutenção com tiossulfato de prata (STS), sob cinco níveis (Água destilada; STS a 0,2 mM; STS a 0,2 mM + sacarose a 50 g L-1; STS a 0,4 mM; STS a 0,4 mM + sacarose a 50 g L-1); e data de amostragem, por três níveis (0; 3; 6 dias). Utilizaram-se três repetições com duas hastes florais em cada tratamento. Foram feitas avaliações físicas: coloração, massa fresca e conteúdo relativo de água (CRA); avaliações químicas: açúcares redutores e pigmentos; e avaliações qualitativas: turgescência, cor das flores, e número de botões, flores entreabertas e abertas. O tratamento com 0,2 mM de STS possibilitou melhor manutenção da massa fresca das hastes. A concentração de pigmentos e carboidratos redutores foi maior naqueles tratamentos em que a sacarose foi associada. A coloração e o conteúdo relativo de água foram favorecidos nos tratamentos STS a 0,2 e 0,4mM. A concentração de 0,2 mM de STS foi a que obteve os melhores resultados, prolongando a vida de vaso das hastes. A qualidade das hastes foi superior, tendo as melhores avaliações de conteúdo de água, cor e turgescência.

Oral health status of people living with HIV/AIDS attending a specialized service in Brazil

Verify factors that influence the oral health status of people living with HIV/AIDS (PLWHA) in Brazil. The study was cross-sectional and includes 177 HIV-positive individuals, who answered questionnaire on the sociodemographic conditions, HIV aspects, habits, and satisfaction with the service. The oral health data were collected by means of the decayed, missing, and filled teeth (DMFT) index, use and need of dentures, and the Community Periodontal Index. Average number of the DMFT was 17.64. Most HIV-positive patients presented good periodontal status, 35.0% used dentures, 41.5% needed denture in the maxilla, and 62.0% in the mandible. In the multivariate analysis, older age and dissatisfaction with health care were associated with nonuse of dentures. The abandonment of the use of antiretroviral therapy increased the risk of PLWHA presenting more than three decayed teeth. Poor oral health of the PLWHA was mainly influenced by sociodemographic factors and use and satisfaction with service.

Um modelo cognitivo baseado na atenção para consciência em robôs inteligentes

Understanding consciousness is one of the most fascinating challenges of our time. From ancient civilizations to modern philosophers, questions have been asked on how one is conscious of his/her own existence and about the world that surrounds him/her. Although there is no precise definition for consciousness, there is an agreement that it is strongly related to human cognitive processes such as: thinking, reasoning, emotions, wishes. One of the key processes to the arising of the consciousness is the attention, a process capable of promoting a selection of a few stimuli from a huge amount of information that reaches us constantly. Machine consciousness is the field of the artificial intelligence that investigate the possibility of the production of conscious processes in artificial devices. This work presents a review about the theme of consciousness - in both natural and artificial aspects -, discussing this theme from the philosophical and computational perspectives, and investigates the feasibility of the adoption of an attentional schema as the base to the cognitive processing. A formal computational model is proposed for conscious agents that integrates: short and long term memories, reasoning, planning, emotion, decision making, learning, motivation and volition. Computer experiments in a mobile robotics domain under USARSim simulation environment, proposed by RoboCup, suggest that the agent can be able to use these elements to acquire experiences based on environment stimuli. The adoption of the cognitive architecture over the attentional model has potential to allow the emergence of behaviours usually associated to the consciousness in the simulated mobile robots. Further implementation under this model could potentially allow the agent to express sentience, selfawareness, self-consciousness, autonoetic consciousness, mineness and perspectivalness. By performing computation over an attentional space, the model also allows the ...
