Abstract: Se realizó un estudio retrospectivo y descriptivo de las muestras de pacientes pediátricos remitidas al laboratorio del Hospital Pi ero durante el período 2004-2008 para el cultivo de micobacterias por sospecha de tuberculosis. Durante dicho período ingresaron un total de 8409 muestras, de las cuales 1542 (18%) fueron pediátricas; de ellas 1407 (91%) pulmonares y 135 extrapulmonares (9%). El procesamiento de las muestras incluyó baciloscopía, cultivo, identificación y prueba de sensibilidad. La nacionalidad de los pacientes pediátricos se distribuyó del siguiente modo: argentinos, 1218 (79%); extranjeros, 247 (16%), representados estos últimos por paraguayos, peruanos y sobre todo bolivianos. Para un 5% de los pacientes no fue informada la nacionalidad. La distribución por sexo fue: femenino, 787 pacientes (51%); masculino, 755 pacientes (49%). De acuerdo con la edad de los pacientes se obtuvo la siguiente distribución: 0 a 4 a os, 674 ni os (grupo A, 45%), 5 a 9 a os, 354 ni os (grupo B, 24%); y 10 a 15 a os, 464 pacientes (grupo C, 31%). Las principales asociaciones mórbidas fueron desnutrición e infección por el virus de la inmunodeficiencia humana. La baciloscopía fue positiva en 41 muestras (2,6%), en tanto que la recuperación mediante cultivo alcanzó las 84 muestras (5,4%), 78 de ellas pulmonares y 6 extrapulmonares. Todas las cepas fueron identificadas como complejo Mycobacterium tuberculosis. Los aislamientos fueron sensibles a estreptomicina, isoniazida, rifampicina y etambutol, excepto una cepa resistente a etambutol y estreptomicina y otra resistente a isoniazida. La confirmación bacteriológica de la tuberculosis pediátrica es difícil de alcanzar debido a la presentación paucibacilar de las muestras, pero juega un papel fundamental en el diagnóstico de certeza, ya que permite la identificación y la realización de las pruebas de sensibilidad del aislamiento. Samples of pediatric patients suspected of tuberculosis and cared for at Hospital Pi ero during the 2004-2008 period were analyzed according to epidemiological and clinical criteria. The bacteriological contribution was evaluated to confirm the disease diagnosis. A descriptive retrospective analysis of the cases was done. A total of 8409 samples were received for mycobacterial culture: 1542 (18%) of which were pediatric and distributed as follows: 1407 (91%), pulmonary and 135 (9%), extra-pulmonary. The sample examination included staining for acid-fast bacilli, culture, identification and drug susceptibility testing. The following are the results of analized demographic variables: National

Abstract: background. as burnout syndrome has been barely analyzed in pediatricians, it was considered relevant to explore labor satisfaction and tiredness in these professionals and to evaluate possible associated factors. population and methods. the maslach burnout inventory questionnaire was voluntarily and anonymously applied to pediatricians. personal and professional variables were included. bivariate and multivariate statistical techniques were employed for analyzing registered data. results. answer rate reached 89%. mean values related with emotional exhaustion, depersonalization and personal achievement were 30.60 ± 10.98, 0.51 ± 5.95 and 35.76 ± 7.32, respectively. it was established that as time of pediatric performance went on, personal achievement increased and depersonalization diminished. depersonalization also decreased in physicians carrying out managerial jobs. the clusters obtained through multivariate analysis showed a higher to lower severity ordination, going from pediatricians with lower personal achievement and higher values of depersonalization and emotional exhaustion (classes 1 and 2) to pediatricians with lower emotional exhaustion, medium depersonalization and higher personal achievement (classes 4 and 5). conclusions. the polled pediatricians evidenced higher values of emotional exhaustion and depersonalization and a medium personal achievement. this dimension became higher as they revealed more years of professional performance. depersonalization was lower in physicians carrying out managerial jobs. multivariate analysis was useful to group individuals in accordance with their affinities on the studied variables.

Can Character Solve Our Problems? Character Qualities and the Imagination Age  [PDF]
María García Alvarez
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.92012
Abstract: The emergence of new technology, incorporation of AI to the work floor and rapid pace of change and complexity around us, contribute to the need for a more sophisticated set of skills as key elements for the 21st century and centuries to come. This paper defends the idea that in the Imagination Age we will require more than just the mastery of traditional foundational literacies. Educational institutions should shift the focus towards the training of character qualities. Meta-competencies directly linked with character will provide students with the ability to deal with complex environments. While the importance of character qualities in education is not new, it will become more relevant to prepare the future generations. Educational institutions are urged to rethink their own methods and roles to prepare students to live and collaborate together with new forms of intelligence.

American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.410235

Plant macronutrient distribution in podzolized sands of the Amazon caatinga has received attention in several studies; however, the distribution of micronutrients has not been assessed. Soil micronutrient availability has been hypothesized to reflect contrasting habitat characteristics as well as fundamental differences in substrate, and leaf micronutrient composition may reflect the macronutrient content needed to maintain balance for leaf cell functions. In this study, soil and leaf samples were obtained in a toposequence (valley, slope, and mound). Available soil micro- and macronutrients as well as total leaf content were measured by inductively coupled plasma-atomic emission spectrometer and mass spectroscopy. Soil Zn (<1.41 mg·kg-1) and B (<0.31 mg·kg-1) as well as Cu (<1.33 mg·kg-1) levels were very low. Soil Mn was low in the valleys and slopes (0.62-0.87 mg·kg-1), but higher in the mound (6.59 mg·kg-1). Soil Fe (11.48-21.13 mg·kg-1) was well above the critical level in all of

Urban Simulation Models: Contributions as Analysis-Methodology in a Project of Urban Renewal*  [PDF]
María Cecilia Marengo
Current Urban Studies (CUS) , 2014, DOI: 10.4236/cus.2014.23028
Abstract: The recent urban transformations produced in cities indicate the need to propose new theoretical and methodological approaches in physical planning. Based on the idea of complexity, it is required to integrate, in the analysis, multiplicity of interrelated factors involved in urban development, moreover, to develop planning tools that can incorporate variables not initially considered (for example when the norms were sanctioned) and instruments that would provide assessment alternatives to planning decisions in real time. The simulation models are suggested as tools to detect the elements, relationships and the dynamics in a simplified form that allow experiencing on the results. That is to say, a theoretical position on to a computer model is translated to investigate (in an experimental way) possible solutions derived from manipulating the variables, before the phenomenon is materialized. In the case of urban planning, this condition is of particular relevance, given the importance to anticipate unwanted effects in the intervention context that may arise when urban projects are built. The paper evaluates the application of a simulation methodology, based on the dynamics of systems and the application of software that can anticipate the effects of certain decisions in an urban renewal project in the city of Córdoba, Argentina. It applies the General Systems Theory that is a contribution to the notion of complex thought and is trans-disciplinary. Based on the idea of complex and multidimensional city, the effects of a real estate development are analyzed and conclusions on the limits and possibilities of using this tool during the processes of urban management are provided.
Density and Housing: Comparative Evaluation towards a Residential Quality Index. The Case of Collective Dwellings in Córdoba—Argentina  [PDF]
María Cecilia Marengo
Current Urban Studies (CUS) , 2017, DOI: 10.4236/cus.2017.51003
Abstract: The crisis on infrastructure systems, mobility and the demands of service provision in increasingly remote areas with less values of urbanity that result from the dispersed city model, leads to reexamining the consolidated and dense tissues. While presenting a more compact land-use, there should be conditions of urban habitability of higher quality than those in the new undifferentiated and diffuse peripheries. In this context, the research analyzes comparatively different residential proposals of collective dwellings as a function of density. The objective of the work is to evaluate, from an architectural design dimension, significant cases of collective housing built in Córdoba city that offer higher levels of densification in relation to the building environment where they are located. It seeks to identify the advantages in terms of residential quality in the different housing proposals that integrate the cases of study and link it with the density adopted in its design. The methodological approach integrates an evaluation matrix that compares housing complexes with different density values. Analytical dimensions related to urban indicators are selected and others with indicators relating to the design of collective housing. Weighting criteria are used to construct a residential quality index (RQI), and to integrate in a simulation model of the concepts: Density and Residential quality. Finally, the results obtained in this first analytical approach of the problem of study are evaluated new interrogations proposed to advance in the analysis of the different levels of densification that are presented in the proposals and their adequacy.
Zeno of Elea Shines a New Light on Quantum Weirdness  [PDF]
María Esther Burgos
Journal of Modern Physics (JMP) , 2017, DOI: 10.4236/jmp.2017.88087
Abstract: After a brief reference to the quantum Zeno effect, a quantum Zeno paradox is formulated. Our starting point is the usual version of Time Dependent Perturbation Theory. Although this theory is supposed to account for transitions between stationary states, we are led to conclude that such transitions cannot occur. Paraphrasing Zeno, they are nothing but illusions. Two solutions to the paradox are introduced. The first as a straightforward application of the postulates of Orthodox Quantum Mechanics; the other is derived from a Spontaneous Projection Approach to quantum mechanics previously formulated. Similarities and differences between both solutions are highlighted. A comparison between the two versions of quantum mechanics, supporting their corresponding solutions to the paradox, shines a new light on quantum weirdness. It is shown, in particular, that the solution obtained in the framework of Orthodox Quantum Mechanics is defective.
Unravelling the Quantum Maze  [PDF]
María Esther Burgos
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.98106
Abstract: The restoration of philosophical realism as the basis of quantum mechanics is the main aim of the present study. A spontaneous projection approach to quantum theory previously formulated achieved this goal in cases where the Hamiltonian does not depend explicitly on time. After discussing the most relevant flaws of orthodox quantum mechanics, a formulation of the spontaneous projections approach in the general case is introduced. This approach yields experimental predictions which in general coincide with those of the orthodox version and overcomes its main flaws.
