A set to locate all eigenvalues for matrices with a constant main diagonal entry is given, and it is proved that this set is tighter than the well-known Geršgorin set, the Brauer set and the set proposed in (Linear and Multilinear Algebra, 60:189-199, 2012). Furthermore, by applying this result to Toeplitz matrices as a subclass of matrices with a constant main diagonal, we obtain a set including all eigenvalues of Toeplitz matrices.

The aim of this paper is to give two new descriptions of the ordered set of all (up to equivalence) regular compactifications of a completely regular frame. F and to introduce and study the notion of A-frame as a generalization of the notion of Alexandroff space (known also as zero-set space) (Alexandroff[l], Gordon[15]). A description of the ordered set of all (up to equivalence) A-compactifications of an A-frame by means of an ordered by inclusion set of some distributive lattices (called AP-sublattices) is obtained. It implies that any A-frame has a greatest A-compactification and leads to the descriptions of A new category isomorphic to the category of proximal frames is introduced. A question for compactifications of frames analogous to the R. Chandler's question [8, p. 71] for compactifications of spaces is formulated and solved. Many results of [1], [3], [15], [23], [9], [10] and [11] are generalized.

ABSTRACTObjective: to analyze how sheltering has been used as a strategy to humanize the attendance in basic attention services.  Methodology: systematic review literature study. It was done a search in the databases SCIELO, LILACS and MEDLINE and included articles published from 2000 to 2008. In examining the articles were classified according to the database, year of publication, place of publication, author, title, and journal. In a subsequent analysis was observed how is used the sheltering as a strategy for humanization of basic care, detecting obstacles and solutions in its execution. Results: nine studies met the criteria for inclusion set. The analysis of the articles showed that the host is a new way to describe the humanization in care and ensure the increase of positive results in primary care, requiring a joint effort of the whole team in the interaction with the user in order to create a relationship of trust and bond with it. Conclusion: the chances to get positive results with sheltering strategy in the basic attention service are big if there is adequate planning, well-organized activities, interaction between the team and link between professional/user, listening with qualified and solution of problems. Descriptors: user embracement; humanization of assistance; primary health care.RESUMO Objetivo: analisar o acolhimento como estratégia para humanizar o atendimento na atenção básica em saúde. Metodologia: estudo de revisão sistemática de literatura, efetuada em bases de dados SCIELO, LILACS e MEDLINE de artigos publicados no período de 2000 a 2008. Na análise os artigos foram classificados segundo base de dados, ano de publicação, local de publicação, autor, título, e periódico. Resultados: nove estudos atenderam aos critérios de inclusão estabelecidos. A análise dos artigos demonstrou que o acolhimento é uma nova forma para qualificar a humanização nos atendimentos e garantir o aumento de resultados positivos na atenção básica, sendo necessário um trabalho conjunto de toda a equipe multiprofissional na interação com o usuário, de modo a criar uma relação de confiança e vínculo com o mesmo. Conclusão: para que se obtenham resultados positivos, com a estratégia do acolhimento na humanização da atenção básica, é necessário que haja planejamento adequado, ações bem organizadas, interação entre a equipe multiprofissional e vínculo entre profissional/usuário, com escuta qualificada e resolutividade dos problemas apresentados. Descritores: acolhimento; humanização da assistência; atenção primaria à saúde.RESUMENObjetivos: analizar cómo acogimiento se ha utilizado como una estrategia para humanizar la asistencia en los servicios de atención básica.

Descriptores: acogimiento; humanización de la atención; atención primaria de salud.

Firstly, the relationships among strictly diagonally dominant ( S D D ) matrices, doubly strictly diagonally dominant ( D S D D ) matrices, eventually S D D matrices and eventually D S D D matrices are considered. Secondly, by excluding some proper subsets of an existing eigenvalue inclusion set for matrices, which do not contain any eigenvalues of matrices, a tighter eigenvalue inclusion set of matrices is derived. As its application, a sufficient condition of determining non-singularity of matrices is obtained. Finally, the infinity norm estimation of the inverse of eventually D S D D matrices is derived.
