A universal systems design process is specified, tested in a case study and evaluated. It links English narratives to numbers using a categorical language framework with mathematical mappings taking the place of conjunctions and numbers. The framework is a ring of English narrative words between 1 (option) and 360 (capital); beyond 360 the ring cycles again to 1. English narratives are shown to correspond to the field of fractional numbers. The process can enable the development, presentation and communication of complex narrative policy information among communities of any scale, on a software implementation known as the "ecoputer". The information is more accessible and comprehensive than that in conventional decision support, because: (1) it is expressed in narrative language; and (2) the narratives are expressed as compounds of words within the framework. Hence option generation is made more effective than in conventional decision support processes including Multiple Criteria Decision Analysis, Life Cycle Assessment and Cost-Benefit Analysis.The case study is of a participatory workshop in UK bioenergy project objectives and criteria, at which attributes were elicited in environmental, economic and social systems. From the attributes, the framework was used to derive consequences at a range of levels of precision; these are compared with the project objectives and criteria as set out in the Case for Support. The design process is to be supported by a social information manipulation, storage and retrieval system for numeric and verbal narratives attached to the "ecoputer". The "ecoputer" will have an integrated verbal and numeric operating system. Novel design source code language will assist the development of narrative policy. The utility of the program, including in the transition to sustainable development and in applications at both community micro-scale and policy macro-scale, is discussed from public, stakeholder, corporate, Governmental and regulatory perspectives.

Many problems in digital communications involve wideband radio signals. As the most recent example, the impressive advances in Cognitive Radio systems make even more necessary the development of sampling schemes for wideband radio signals with spectral holes. This is equivalent to considering a sparse multiband signal in the framework of Compressive Sampling theory. Starting from previous results on multicoset sampling and recent advances in compressive sampling, we analyze the matrix involved in the corresponding reconstruction equation and define a new method for the design of universal multicoset codes, that is, codes guaranteeing perfect reconstruction of the sparse multiband signal.

Motivation: Influenza A viral heterogeneity remains a significant threat due to unpredictable antigenic drift in seasonal influenza and antigenic shifts caused by the emergence of novel subtypes. Annual review of multivalent influenza vaccines targets strains of influenza A and B likely to be predominant in future influenza seasons. This does not induce broad, cross protective immunity against emergent subtypes. Better strategies are needed to prevent future pandemics. Cross-protection can be achieved by activating CD8+ and CD4+ T cells against highly-conserved regions of the influenza genome. We combine available experimental data with informatics-based immunological predictions to help design vaccines potentially able to induce cross-protective T-cells against multiple influenza subtypes. Results: To exemplify our approach we designed two epitope ensemble vaccines comprising highly-conserved and experimentally-verified immunogenic influenza A epitopes as putative non-seasonal influenza vaccines; one specifically targets the US population and the other is a universal vaccine. The USA-specific vaccine comprised 6 CD8+ T cell epitopes (GILGFVFTL, FMYSDFHFI, GMDPRMCSL, SVKEKDMTK, FYIQMCTEL, DTVNRTHQY) and 3 CD4+ epitopes (KGILGFVFTLTVPSE, EYIMKGVYINTALLN, ILGFVFTLTVPSERG). The universal vaccine comprised 8 CD8+ epitopes: (FMYSDFHFI, GILGFVFTL, ILRGSVAHK, FYIQMCTEL, ILKGKFQTA, YYLEKANKI, VSDGGPNLY, YSHGTGTGY) and the same 3 CD4+ epitopes. Our USA-specific vaccine has a population protection coverage (portion of the population potentially responsive to one or more component epitopes of the vaccine, PPC) of over 96% and 95% coverage of observed influenza subtypes. The universal vaccine has a PPC value of over 97% and 88% coverage of observed subtypes.

En este artículo se presenta el diseño de la nueva formación en intervención social para todas las personas desde la accesibilidad universal, en concreto el caso de las profesiones sociales, a través de la metodología del design thinking curricular. En el mismo se trata la relación íntima que surge de vincular dos conceptos, por un lado la inclusión –que responde positivamente a la diversidad de las personas y a las diferencias individuales, entendiendo que la diversidad no es un problema, sino una oportunidad para el enriquecimiento de la sociedad, a través de la participación activa en la vida familiar, en la educación, en el trabajo y en general en todos los procesos sociales, culturales y en las comunidades (UNESCO, 2005)– y, por otro, la accesibilidad, como nuevo paradigma de la integralidad en la intervención de los/as nuevos/as profesionales dedicados al sector social, haciendo realidad el concepto de ciudadanía en sentido amplio.

During the process of accessing services provided within urban interior and outer spaces the elderly and disabled individuals encounter with a myriad of problems due to the limitations posed by structured environments. This limitation hinders elderly and disabled individuals from mobility without assistance, which in turn negatively affects their full participation to urban and social life. Rearrangement of urban spaces to meet the needs of elderly and disabled individuals would correspondingly bolster life quality of the entire range of users. Within the scope of present research, as mandated by universal design principles to stick to plans and designs approaches inclusive for all users, it is aimed to conduct evaluations on the use of urban outer spaces situated within Konya City Center. In the hypothetical and theoretical part of this paper, the perception of disability throughout historical process has been examined from a sociological perspective. In addition, concept of universal design, its principles and gravity have also been elaborated. In the part dealing with the case study, outer spaces within Konya City Center have been analyzed with respect to universal design principles and a range of suggestions have been developed.

The aim of this mental health promotion initiative was to evaluate the effectiveness of a universally delivered group behavioral family intervention (BFI) in preventing behavior problems in children. This study investigates the transferability of an efficacious clinical program to a universal prevention intervention delivered through child and community health services targeting parents of preschoolers within a metropolitan health region. A quasiexperimental two-group (BFI, n=804 vs. Comparison group, n=806) longitudinal design followed preschool aged children and their parents over a 2-year period. BFI was associated with significant reductions in parent-reported levels of dysfunctional parenting and parent-reported levels of child behavior problems. Effect sizes on child behavior problems ranged from large (.83) to moderate (.47). Positive and significant effects were also observed in parent mental health, marital adjustment, and levels of child rearing conflict. Findings are discussed with respect to their implication for significant population reductions in child behavior problems as well as the pragmatic challenges for prevention science in encouraging both the evaluation and uptake of preventive initiatives in real world settings.

This study evaluated the effect of framework design on the fracture resistance of metal-ceramic implant-supported crowns. Screw-retained molar crowns with a screw access hole composed of metal or porcelain were compared to a cement-retained crown (control). For each group (n = 10), five crowns were subjected to dynamic loading (1,200,000 x 100 N x 2 Hz at 37 degrees C). Afterward, all specimens were loaded to failure using a universal testing machine. Significant differences could be established between the cement-and screw-retained groups (P <= .05), but no difference was found between the screw-retained groups and the specimens subjected to dynamic loading. Occlusal discontinuity of screw-retained crowns affects their resistance, and the metallic support on the screw access hole did not reinforce the crowns. Int J Prosthodont 2010;23:350-352.

Este trabalho teve o intuito de criar uma linha de montagem universal através da qual será dada formação aos atuais operadores e a novos que possam vir a pertencer ao departamento de montagem na empresa Grohe Portugal. Para tal era necessário saber realizar um estudo de métodos e um estudo de tempos sobre os vários processos existentes no departamento de montagem. Com esse intuito foi elaborada uma pesquisa sobre as referidas temáticas, onde ficou evidente a sua importância e a sua imprescindibilidade. Inicialmente houve também um acompanhamento das montagens dos produtos nas várias linhas, de forma a adquirir conhecimento sobre as características dos processos de montagem existentes no departamento. Os pontos mais importantes durante o estudo de métodos e tempos realizado foram a definição de toda a estrutura do processo, das ferramentas e materiais a utilizar, não esquecendo a relação entre o operador e as suas ferramentas e a medição de tempos de todas as tarefas necessárias para cada processo de montagem. A linha de montagem, cujo projeto se desenvolveu, é composta por três bancadas e consiste num conjunto de postos de trabalho onde são executadas as operações através de máquinas, do trabalho humano, ou da sua conjugação, dispostos numa determinada sequência, sendo alguns deles amovíveis. Para a realização e conclusão deste projeto foram superadas diversas etapas, sendo que as mais relevantes foram:  a análise dos processos de montagem;  estudo de tempos de todas as famílias de produtos a serem implementados na linha de formação; - Definição da estrutura da linha de montagem; - Definição das rampas e dos tubos de abastecimento da linha; - Desenho da linha de montagem em 3D no software SolidWorks. Paralelamente foram também desenvolvidos estudos de tempos sobre alguns produtos com o intuito de serem implementadas melhorias, ou apenas para o controlo de tempos necessários para a realização das operações Por último, foi também elaborada uma recolha de ferramentas existentes no departamento de montagem para serem elaborados manuais de instruções das ferramentas fabricadas internamente, com o objetivo de obter a certificação OSHAS 180001 e de criar documentos com a listagem de materiais necessários para cada produto.
