Concepciones ideológicas acerca del derecho en la obra de Cicerón

El análisis de De Legibus y De Re Publica permite reflexionar acerca de la ideología en, relación al derecho, subyacente en la obra de Cicerón, principal representante del pensamiento de los optimatas. Partiendo de referenciales semióticos, las obras son abordadas con el objeto de determinar las estructuras de tipo lógico-semántico más básicas, para observar el lugar que ocupaba el derecho en la cosmovisión de los «mejores ciudadanos», así como comprender por qué las leyes eran consideradas como legítimas o ilegítimas.The analysis of De Legibus and De Re Publica prompts thoughts about ideology with regard to law, a perception that permeates all of Cicero's work. The texts in question have been studied using a semiotic approach to determine the most basic types of logic-semantic structures, in order to determine the role played by law in the cosmo visión of the "best citizens", and thus understand how the legality and ¡liegality of law per ser, was determined

Mortality information: the use of international rules for the selection of the underlying cause

A análise da mortalidade tem sido muito usada em saúde pública, e a causa básica da morte é uma variável bastante estudada. Na maioria dos países, há obrigatoriedade de o médico preencher a declaração de óbito (DO), informando às autoridades a ocorrência do evento, características do falecido e causas da morte. Quando há dois ou mais diagnósticos na declaração das causas da morte, surge a questão da seleção da causa básica. As normas para o preenchimento das causas de morte pelos médicos nas DO e as regras para a seleção da causa básica, quando mais de uma causa é declarada, estão definidas pela OMS, visando à comparabilidade internacional. O objetivo deste trabalho é avaliar se a aplicação das Regras Internacionais de Classificação da causa básica permite a seleção da real causa básica, mesmo se declarada incorretamente pelo médico. O material pertence ao "Estudo sobre a mortalidade de mulheres em idade fértil", sendo que 1.315 casos satisfizeram os requisitos de inclusão. Para cada morte foi realizada uma investigação através de entrevistas domiciliárias, consultas aos prontuários hospitalares e assemelhados. Médicos treinados e calibrados preenchiam uma DO nova, após a leitura de toda a informação, e selecionavam a "verdadeira" causa básica da morte. Esta era comparada com a causa básica da DO original, obtida por meio das Regras Internacionais. Entre as DO, em 1.192 (90,6%) houve concordância com a verdadeira causa básica obtida após a investigação. Concluiu-se que as Regras Internacionais permitem selecionar a real causa básica, mesmo quando o médico preenche inadequadamente a DOMortality analysis is often used in public health and the cause of death is an important variable. In most countries, there is a requirement for physicians to fill out a death certificate (DC) and to send it to authorities informing its occurrence, characteristics of the deceased, and causes of death. When there are two or more diagnoses in the DC as causes of death, it raises the question of how to select the underlying cause. There are International Rules for filling out medical causes of death in the DC and rules for the selection of the underlying cause when more than one cause is declared. The WHO defined and included them in the International Classification of Diseases, aiming to have international comparability. The objective is to evaluate whether the application of International Rules allows the selection of the real underlying cause, even if causes of death were poorly declared by the physician. The cases belong to the "Study on mortality of childbearing age women" from which total of 1,315 DC were selected. For each death, an investigation was conducted through household interviews, consultation to hospital records, and autopsies. Physicians were trained to fill a new DC, after reading all the information, and to select the real underlying cause. This cause selected after the investigation was compared to the corresponding cause in the original DC, obtained by means of the International Rules. Results showed that in 1,192 (90.6%) original DC there was agreement with the real cause obtained with the investigation. The conclusion was that International Rules allow a trained coder to select the real underlying cause, even when the physician fills the DC incorrectlyMinistério da Saúde - Secretaria de Atenção à Saúde.

Mitigation of numerical Cerenkov radiation and instability using a hybrid finite difference-FFT Maxwell solver and a local charge conserving current deposit

A hybrid Maxwell solver for fully relativistic and electromagnetic (EM) particle-in-cell (PIC) codes is described. In this solver, the EM fields are solved in $k$ space by performing an FFT in one direction, while using finite difference operators in the other direction(s). This solver eliminates the numerical Cerenkov radiation for particles moving in the preferred direction. Moreover, the numerical Cerenkov instability (NCI) induced by the relativistically drifting plasma and beam can be eliminated using this hybrid solver by applying strategies that are similar to those recently developed for pure FFT solvers. A current correction is applied for the charge conserving current deposit to correctly account for the EM calculation in hybrid Yee-FFT solver. A theoretical analysis of the dispersion properties in vacuum and in a drifting plasma for the hybrid solver is presented, and compared with PIC simulations with good agreement obtained. This hybrid solver is applied to both 2D and 3D Cartesian and quasi-3D (in which the fields and current are decomposed into azimuthal harmonics) geometries. Illustrative results for laser wakefield accelerator simulation in a Lorentz boosted frame using the hybrid solver in the 2D Cartesian geometry are presented, and compared against results from 2D UPIC-EMMA simulation which uses a pure spectral Maxwell solver, and from OSIRIS 2D lab frame simulation using the standard Yee solver. Very good agreement is obtained which demonstrates the feasibility of using the hybrid solver for high fidelity simulation of relativistically drifting plasma with no evidence of the numerical Cerenkov instability

Maternal deaths and mortality due to a maternal underlying cause of death

Ao mensurar-se mortalidade materna, é necessário distinguir ' mortes por causas maternas' e 'mortes maternas' Para a Organização Mundial da Saúde-OMS-,mortes maternas são as que ocorrem na gestação, no parto e até 42 dias após o parto; e mortes por causas maternas englobam as causas classificadas no Capítulo XV da Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde, Décima Revisão (CID-10), incluindo as ocorridas quando passados 42 dias do parto. Apresentam-se resultados da investigação de mortes femininas em idade fértil-10 a 49 anos- nas capitais de Estados e no Distrito Federal do Brasil, em 2002. Adotou-se a metodologia RAMOS, comparando-se as causas básicas das declarações de óbito originais com as das declarações preenchidas após o resgate de informações, obtidas em entrevistas domiciliares e prontuários. Entre as mortes por causas maternas originais, 15,9 por cento não eram mortes maternas, de acordo com a definição da OMS. Houve, concomitantemente, subenumeração de mortes maternas. Sugestões são feitas para melhorar o preenchimento das declarações de óbito e inclusão de novas categorias na CID-10, visando melhorar a informação das causas maternasIt is necessary to distinguish 'maternal deaths' from 'deaths due to maternal causes', as underlying causes, when measuring maternal mortality. World Health Organization – WHO – defines maternal deaths as those occurred during pregnancy and until 42 days of puerperium, and maternal causes like all deaths classified in Chapter XV of Statistical Classification of Diseases and Related Health Problems, 10th Revision – ICD-10th Revision –, including even those occurred after 42 days of postpartum. Some results of the investigation of women in childbearing age – 10 to 49 years old – deaths, residents in Brazilian capitals and the Federal District in 2002, are discussed. The RAMOS methodology was adopted. Comparing the underlying causes of the original death certificates with those filled after the household interview and consulting of hospital records, 15.9% of deaths due to maternal causes were not maternal deaths in fact, according to WHO definition; there was also a sub-enumeration of maternal deaths. It is recommended to improve the filling of death certificate by physicians, and inclusion of new categories in the ICD-10th Revision, regarding maternal cause

Calibration standars of nuclear microprobes

El Micro-haz de iones Pesados (MiP) del laboratorio Tandar constituye un instrumento de características únicas en el país, pues puede proveer haces de iones pesados de dimensiones micrométricas acelerados hasta decenas de MeV de energía. La búsqueda de tamaños de haz más pequeños ha creado la necesidad de contar con estándares de calibración de elevada calidad de resolución. En el presente trabajo se desarrollaron los primeros prototipos para calibrar la focalización del haz: estructuras metálicas de cobre o niquel en forma de grilla con orificios cuadrados. Se emplearon dos métodos de fabricación. En el primero se utilizaron técnicas de fotolitografía convencional sobre un sustrato de silicio con foto-resina, mientras que en el segundo se utilizó el MiP para micro-mecanizar sustratos de Niobato de Litio (LiNbO3). En ambos casos se finalizó el proceso de fabricación del patrón con electrodeposición de cobre o níquel sobre la matriz desarrollada. Mediante la técnica fotolitográfica se fabricaron grillas de níquel que varían entre 130 y 180 mesh**. Mediante micro-mecanizado con el MiP se fabricaron grillas de cobre de entre 500 y 2000 mesh sobre sustratos de LiNbO3.The Micro-heavy ion beam (MiP) at Tandar’s Lab is a unique instrument in the country, as it can provide heavy ion beams at micrometer-scale accelerated to tens of MeV energy. The quest for smaller beam sizes has created the need for calibration standards of high resolution quality. In this paper we developed the first prototypes to calibrate the beam focusing: metal structures of copper or nickel shaped grid with square holes. We used two methods of manufacture. Were used in the first conventional photolithography techniques on a silicon substrate with photoresin while the second was used for micromachining with MiP substrates of lithium niobate (LiNbO3). In both cases the process for the manufacture was finished with electro-deposition of copper or nickel on the matrix developed. By photolithographic technique nickel grids were manufactured varying between 130 and 180 mesh. By MiP micromachining copper grids were produced between 500 and 2000 mesh on LiNbO3 substrates.Fil: Arena, S.. Universidad de Buenos Aires.

Maternal deaths: reviewing the adjustment factor for official data

O objetivo foi comparar as mortes maternas existentes no Sistema de Informações sobre Mortalidade (SIM/MS) com as do "Estudo da mortalidade de mulheres em idade fértil" e estimar novos fatores de correção. Analisaram-se 7.332 declarações de óbito feminino (DO) de dez a 49 anos, de residentes nas capitais brasileiras, no 1o semestre de 2002. Realizou-se pareamento dos conjuntos de DO (as originalmente preenchidas pelos médicos e aquelas obtidas com o resgate de dados) com as DO do SIM/MS. A subenumeração das mortes por causas maternas, no SIM/MS, foi de 21,4 por cento e, das mortes maternas, 16 por cento . Os novos fatores de ajuste para as mortes maternas nas regiões brasileiras foram: 0,93 (Norte), 1,17 (Nordeste), 1,28 (Sudeste), 1,10 (Sul) e 1,47 (Centro-oeste); para o pa's, foi igual a 1,19. Os Comitês de Morte Materna investigam os óbitos femininos em idade fértil, mas, ainda, restam imprecisões que podem inviabilizar condutas preventivas eficientesThe objectives were to compare maternal deaths notified at the Ministry of Health Information System on Mortality (SIM/MS) with those detected in the "Study on the mortality of fertile women in Brazil" and to estimate a new adjustment factor. A total of 7,332 official death certificates (DC), from the 1st semester of 2002, of women aged 10-49, residents in the nation's state capitals, were analyzed. Database linkage was performed to compare the underlying cause of death at SIM/MS with the study results. Data show there was inadequate notification of deaths due to maternal causes (21.4%) and to maternal deaths (16%). The new national adjustment factor for maternal deaths was 1.19. Committees on Maternal Mortality are efficient; nevertheless, there is lack of information on official deaths, which could make it difficult to manage adequately the situationMinistério da Saúde, Organização Pan-Americana da Saúde e Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) do Ministéreio da Ciência e Tecnologi

Brazilian mortality of elderly persons: the question about ill-defined underlying causes of death

O envelhecimento populacional é um fato marcante da transição demográfica. O estudo das causas básicas em idosos permite visualizar seu perfil epidemiológico, embora possa ser prejudicado pela alta proporção de causas mal definidas. O objetivo deste trabalho é descrever a mortalidade dos idosos por essas causas no Brasil. A fonte dos dados foi o Sistema de Informações sobre Mortalidade do Ministério da Saúde.Entre as variáveis, a principal modalidade foi a causa básica mal definida [ Capítulo XVIII da Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde-Décima Revisão (CID-10)]. O decréscimo desses óbitos em idosos foi de 35 por cento entre 1996 e 2005.Considerando os óbitos de 60 a 69 anos e os de 80 e mais anos, as proporções de mal definidos aumentaram em 9,9 por cento e 14,8 por cento, respectivamente, no ano de 2005. Métodos visando a sua diminuição são sugeridos, salientando-se que o fato mais importante é o de os médicos preencherem adequadamente as declarações de óbito- com as reais causas básicas, conseqüênciais e terminais-, objetivo maior dos estudiososThe study of mortality of elderly persons according to underlying causes permits the understanding of their epidemiological profile; but there is a large proportion of ill-defined causes. The objective of this work is to describe the Brazilian elderly mortality according to ill-defined underlying causes. Data source was the System of Information on Mortality of the Ministry of Health. Among variables, the ill-defined underlying cause of death was the main one [Chapter XVIII, International Statistical Classification of Diseases and Related Health Problems – 10th Revision (ICD-10)]. There was a 35% decrease in the occurrence of them observing the elderly deaths, from 1996 to 2005. An increase on the ratios (ill-defined/all deaths) was detected in 2005 from the deaths of 60 to 69 years to the deaths of 80 and more years: 9.9% and 14.8%, respectively. Methodologies to diminish these proportions are suggested; however, the most relevant factor is an adequate report by the physicians of the actual causes of death – underlying, associated and complications – in the death certificate

Perinatal mortality in hospitals of the state of São Paulo: methodological aspects and some characteristics of mothers and conceptuses

Objective: to verify perinatal mortality and its associated components in an investigation about the history of gestations/deliveries. Method: the study was carried out at six maternity hospitals in the State of São Paulo that were interested in participating in the research. The population was composed of 7,058 women, of whom 6,530 gave birth, the number of conceptuses was 6,602: 56 stillbirths and 6,546 live births, of which 28 died in the first week of life. Variables related to the mother, the pregnancy, the delivery and the conceptus were studied. Results: the perinatal mortality coefficient was 12.7 per 1,000 births, 66.7% of the conceptuses were stillbirths and 33.3% were live births who died aged less than 7 days at the same hospital where they were born. Approximately 27% of the conceptuses were children of adolescent mothers and 44% of the mothers were primigravidae. Prenatal assistance was attended by 92% of the women, type of pregnancy showed 67.8% of preterm gestations with similar proportions for each one of the components. The coefficient for twin gestations was more than four times higher than the coefficient for mothers of singleton gestations. Regarding type of delivery, Cesarean sections corresponded to 31.1% of the total, and it is important to notice that there was a non-negligible amount of surgical deliveries in mothers whose product was a stillbirth. The coefficient according to sex was higher for males (1.8: 1), and as for birth weight, the highest proportion occurred among those who weighed less than 2,500g (67.9%). Conclusions: there was a relationship of the proportion of neonatal deaths in the first hours of life and the proportion of fetal deaths to the quality of the care offered in the women’s pregnancy-puerperal cycle

THE IMPORTANCE OF CONGENITAL MALFORMATIONS AT BIRTH

Introduction: Countries that have overcome high infant mortality rates show, nowadays, concentration of deaths in the neonatal period and, within it, mainly in the first week of life (early neonatal deaths). Regarding causes of death, as some diseases have started to be controlled, a significant proportional increase in the participation of congenital malformations has been verified. Objective: To describe the prevalence of congenital malformations (CM) at birth in conceptuses (stillbirths and live births) of women hospitalized in institutions located in the city of São Paulo, Brazil. Methods: Descriptive, cross-sectional study carried out at 4 hospitals in the city of São Paulo during 3 months in the 2 and semester of 2011. Data were collected by means of interviews with the women and examinations of hospital records. The CM were studied according to variables of epidemiological and socio-demographic interest. The deaths were analyzed according to underlying and associated causes. Results: The results showed the occurrence of 9.1% of CM registered among stillbirths and 4.3% among live births. Among the latter – 238 newborns – 284 CM were registered, totaling 1.2 CM per live birth with CM registered. Among the 238 newborns that had a CM register, there were 10 deaths by CM (4.2%). This value differs from the one verified among the live births without CM register that died (19 out of 5,341 or 0.4%). Aiming to identify possible  occurrences of death after hospital discharge, a linkage was performed between the official mortality database of the city of São Paulo and the study’s database. The occurrence of 18 deaths was found in this way, 4 of which were caused by CM. Thus, the total of deaths in the 1 st year of life was 47, and 14 of them had CM as the underlying cause, which leads to a proportional infant mortality by CM equal to 29.8% and an infant mortality coefficient by CM of 2.5%o live births. The data show a high undercount of CM in the registers of the official information systems (regarding SINASC, the prevalence of CM in the study was three times the prevalence for the city of São Paulo and 5.4 times the prevalence for Brazil). Conclusion: It is necessary to implement measures to improve the register of CM in the information systems, such as: raising doctors’ awareness concerning the importance of diagnosing CM and registering it in the newborn’s hospital records, creating a specific space to register the CM in the newborn’s hospital records, and qualifying and monitoring the personnel in charge of filling in the Certificate of Live Birth and transcribing it to the information systems
