ABSTRACT The objective of this study was the evaluation of egg quality of 30 to 45-week-old brown layers, raised in cages or on floor, supplemented with amino acids, using the ideal protein concept with levels of 14, 15, 16, and 18% crude protein. A total of 400 birds (Hy-sex Brown) were used, distributed into two breeding systems (conventional cage or floor). The evaluated variables were the yolk relative weight, yolk height, albumen relative weight, albumen height, specific gravity, eggshell thickness, and eggshell weight. Treatments consisted of reduced levels of crude protein and were provided to both groups equally. We adopted a completely randomized design, in a factorial scheme, composed of two breeding systems and four levels of crude protein, totaling eight treatments. Five replicates per treatment and 10 birds per experimental unit were used. The breeding system on floor was configured as an option in the breeding of brown layers, of Hy-sex Brown commercial lineage, in the period between the 30th and the 45th week of age, since it presents results equivalent to the ones obtained in the breeding system in cages, having the egg quality as parameter. The system of production on floor is configured as an option in the farming of brown layers, of the commercial lineage Hy-sex Brown.

A memória é um sistema múltiplo constituído por subsistemas de codificação, armazenamento e recuperação de informações. A memória tátil relaciona submodalidades da memória e percepção háptica e se trata da manipulação ativa dos objetos. Este estudo trata-se de uma revisão sistemática sobre o esquecimento ocorrido na memória háptica. Buscou-se nas bases de dados eletrônicas PsycINFO, PubMed, e Web of Science, utilizando as palavras-chave "haptic memory", "touch memory", "tactile memory", "tactual memory" de forma separada, e posteriormente combinadas com a palavra "forgetting". Essas palavras foram identificadas em 1.655 publicações, das quais foram selecionados por um conjunto de critérios de inclusão, seis artigos publicados entre 2002 e 2012. Grande parte dos estudos remeteu-se a métodos comportamentais sobre o reconhecimento de objetos reais. Contudo, os tipos de teste de memória utilizados, bem como o número de objetos e o intervalo de tempo entre as sessões de teste tiveram grande variação.

Memory is a multiple system composed of encoding, storage and retrieval of information subsystems. The memory tactile, haptic memory submodality is connected to haptic perception; it concerns the active manipulation of objects. This study is a systematic review related to forgetting occurred in haptic memory. Articles was sought in electronic databases PsycINFO, PubMed, and Web of Science, using the keywords "haptic memory", "touch memory", "tactile memory", "tactual memory" separately, and then combined with the word "forgetting". These words were identified in 1655 publications. But lastly, six articles published between 2002 and 2012 were selected by a set of inclusion criteria. Largely referred to studies that used behavioral methods recognition procedures, and using real objects. However, the types of memory test used and the number of objects and the time interval between sessions of study and test had great variation.

OBJETIVO: Avaliar a PET/CT na abordagem de pacientes com câncer de cabeça e pescoço. MATERIAIS E MÉTODOS: Estudo retrospectivo de 63 prontuários e exames de PET/CT de pacientes com câncer de cabeça e pescoço. RESULTADOS: Foram encontradas alterações em 76% dos exames. Destes, 7 (11%) foram considerados falso-positivos, com SUV < 5,0. A PET/CT mostrou-se negativa em 15 situações (24%). Dos 14 casos nos quais se utilizou o exame para estadiamento, em 3 (22%) houve aumento no estadiamento. CONCLUSÃO: A PET/CT mostra-se como exame de potencial valor na rotina de avaliação de pacientes com câncer de cabeça e pescoço, entretanto, necessitamos de maior número de casos para definirmos protocolo de uso.

OBJECTIVE: To evaluate the role of PET/CT in the approach to patients with head and neck cancer. MATERIALS AND METHODS: Retrospective study of medical records and PET/CT images of 63 patients with head and neck cancer. RESULTS: Alterations were observed in 76% of the cases. Out of these cases, 7 (11%) were considered as false-positive, with SUV < 5.0. PET/CT demonstrated negative results in 15 cases (24%). Among the 14 cases where the method was utilized for staging, 3 (22%) had their stages changed. CONCLUSION: PET/CT has shown to be of potential value in the routine evaluation of patients with head and neck cancer, but further studies of a higher number of cases are required to define a protocol for utilization of the method.

Impulsionadas pela globalização, empresas transnacionais, instaladas no Brasil, estão colaborando para a formação de um novo perfil profissional para executivos brasileiros. As mudanças que derivam deste cenário passam a exigir dos profissionais conhecimentos e aptidões diferenciadas para a atuação no ambiente atual de negócios. O presente estudo busca traçar o perfil ideal do executivo em face das exigências do mercado globalizado, destacando-se os principais atributos que este profissional deve apresentar, segundo a visão de profissionais decisores das 500 maiores empresas do ranking da revista Exame (1997). Realizou-se uma pesquisa descritiva, a partir de duas etapas: uma exploratória, na qual se geraram os atributos a serem avaliados e uma quantitativa, para a mensuração do grau de importância de cada indicador arrolado. Os atributos referentes ao perfil do executivo no mercado considerados mais importantes são: integridade, visão estratégica, liderança, conhecimento das operações da empresa, capacidade de decisão, negociação e coordenação de trabalhos em equipe, foco nos resultados, ética no trato das questões profissionais e sociais, motivação, pró-atividade e habilidade para o trato interpessoal.

The globalization process has led the Brazilian transnational companies to redefine their executives' profiles. Implementing these changes requires specific knowledge and capabilities in order to act in the current business environment. Presently, the goal of the study is to describe the profile of the executive facing the demands of a global market. We emphasized the main attributes that this executive must have as described by the visionaries of the top 500 companies ranking from Exame Magazine (1997). To do this we implemented a descriptive research in two stages: (1) an exploratory research which generated the attributes that will be evaluated and; (2) a quantitative stage to measure the degree of importance for each indicator.The executive principal attributes on the global market are: integrity, strategic view, leadership, business operations knowledge, ability to make decisions, ability to negotiate and coordinate team efforts, profit mindedness, ability to understand social and professional ethical questions, motivation, proactivity and the skills to manage interpersonal relationships.
