Enterprise Architecture as a Tool for Digital Transformation

Enterprise Architecture (EA) is the holistic expression for the main strategies of an enterprise in terms of business, applications and technologies, and the impact they have on its processes and functions. Currently, the CEOs of most businesses are investigating what opportunities are afforded by digitalization. However, despite the benefits of EA, and its possible role in digital transformation, there is a gap in the research regarding how to take advantage of EA in digital transformation. This article explores the concepts of EA and digital transformation based on a set of publications we selected from the area of IS/IT, and addresses some contributions to a methodology that promotes EA planning as a tool for digital transformation. As such, we refer to the dimensions, the approach, and the two phases of development which will contribute to placing EA as a tool for solving the problems of digital transformation initiatives

From business process modeling to data model : a systematic approach

Business process modeling and management approaches are increasingly used and disclosed between organizations as a means of optimizing and streamlining the business activities. Among the various existing modeling languages, we stress the Business Process Model and Notation (BPMN), currently in version 2.0. BPMN is a widespread OMG standard that is actually used either in academia and in organizations. BPMN enables business process modeling, but does not facilitate the modeling of the information infrastructure involved in the process. However, interest in the data and its preservation has increased in BPMN’s most recent version. The aim of this paper is to study BPMN 2.0, particularly on the usage and persistence of data, and present an approach for obtaining an early data model from the business process modeling, which may then be used as a starting data model in the software development process

Maternal anemia and birth weight : a prospective cohort study

Objective To investigate the association between maternal anemia and low/insufficient birth weight. Design A prospective cohort study of pregnant women who underwent prenatal care at the healthcare units in a municipality of northeast Brazil together with their newborn infants was carried out. The pregnant women were classified as having anemia when the hemoglobin level was below 11 g/dl. Infants who were born full term weighing less than 2500 grams were classified as low birth weight, and those weighing between 2500 and 2999 grams were classified as insufficient weight. The occurrence of maternal anemia and its association with birth weight was verified using crude and adjusted Relative Risk (RR) estimates with their corresponding 95% confidence intervals (95%CIs). Results The final sample was comprised of 622 women. Maternal anemia was considered a risk factor for low/insufficient birth weight, after adjusting the effect measurement for maternal age, family income, urinary infection, parity, alcoholic beverage consumption during pregnancy and gestational body mass index: RRadjusted = 1.38 [95% CI: 1.07 to 1.77]. Conclusions Maternal anemia was associated with low/insufficient birth weight, representing a risk factor for the gestational outcomes studied

AUTOAVALIAÇÃO DA CONDIÇÃO DE SAÚDE DA POPULAÇÃO BAIANA

Objetivo: Descrever a autoavaliação da condição de saúde da população baiana, de acordo com alguns fatores sociodemográficos. Método: Estudo de caráter transversal, cujo banco de dados utilizado foi da Pesquisa Nacional de Saúde (PNS). Foram levantados dados de 6153 pessoas, de ambos os sexos, com faixa etária acima de 18 anos, residentes na Bahia. As variáveis selecionadas foram sexo, raça/cor, estado civil, plano de saúde, diagnóstico de doença crônica, presença de depressão nas últimas semanas, nível de instrução, faixa etária e condição de saúde. Aplicou-se o teste qui-quadrado na análise dos dados, por meio do pacote estatístico Stata 15. Resultados: Definiram seu estado de saúde como bom: 56,88% dos homens, 68,87% dos indivíduos com faixa etária entre 18 e 29 anos, união estável/livre (56,24%), com plano de saúde (58,27%), ensino médio incompleto (73,66%). Em contrapartida, a maior parte das pessoas deprimidas a mais de uma semana (59,44%) e aquelas com doenças crônicas (54,48%) classificaram seu estado de saúde como regular. Conclusão: A maioria das pessoas relatou seu estado de saúde como bom. Destaca-se que essa definição foi mais frequente em pessoas do sexo masculino, jovens, com companheiro, que possuem plano de saúde e maior escolaridade

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Qualidade de vida de indivíduos com HIV: revisão integrativa / Quality of living of individuals with HIV integration review

 A qualidade de  vida de pacientes vivendo com HIV/AIDS é essencial, tendo em vista o caso específico dos adolescentes é ainda mais importante porque o jovem além de lidar com a resistência e a aceitação da doença, deve também enfrentar os conflitos da puberdade.O presente trabalho tem como objetivo realizar uma revisão integrativa em relação a qualidade de vida dos pacientes com HIV. Trata-se de um estudo de revisão integrativa realizado no período de 2016 a 2017, utilizando-se o banco de dados Medline e Lilacs. Apesar do impacto da infecção pelo HIV/AIDS na saúde psicológica e nas relações sociais dos indivíduos infectados, assim como no domínio físico, o uso da TARV provocou consequências positivas na saúde psicológica, proporcionando a desconstrução da ideia de morte advinda ao diagnóstico de portador do HIV/AIDS e a construção de melhores perspectivas de vida. A adesão ao tratamento em HIV/AIDS está relacionada a um aumento da sobrevida e de sua qualidade. Porém deve-se respeitar a posição pessoal do portador para fazer ou não o tratamento

Derivation of data-driven software models from business process representations

usiness process modeling and management ap- proaches are increasingly used and disclosed between organiza- tions as a means to improve their products or services quality and to improve their productivity. If on one hand Business Processes Management and Modeling is becoming increasingly important to organizations, on the other hand, software development teams still have serious difficulties in defining the requirements for the software that supports the business processes which primarily have been based on lists of needs felt by users. As a result, we have software models and applications that are not aligned with business processes. Basing requirements elicitation in the Business Process Modeling would ensure the alignment between Business Processes and software models and applications. The main objective of this research is helping to close the gap between the business processes and the software that supports the business, deriving early software models from business process models.This work has been supported by FCT - Fundação para a Ciência e Tecnologia within the Project Scope: PEst-OE/EEI/UI0319/2014

On the decomposition of use case diagrams for the refinement of requirements

Requirements elicitation is a complex and usually longstanding but crucial activity to the software development. UML use case models are one of the most popular techniques to describe the functional requirements of a system. Use cases can be written with a high-abstraction level or with a low- abstraction level. In fact, when one needs to see the system as a whole, the high-abstraction level use cases are useful. But when the system’s details need to be known, low-abstraction level use cases are a lot more useful. This paper describes an iterative and incremental approach to support the construction of UML use case diagrams as a first documentation effort of the requirements elicitation activities. The approach adopts a refinement mechanism to detail use cases, in a controlled way, as a mean to obtain a functional requirements model of the system. This allows relating an abstract use case with the corresponding more concrete use cases.This work has been supported by Fundação para a Ciência e a Tecnologia (FCT) within the Project Scope: PEst-OE/EEI/UI0319/201

On the rim between business processes and software systems

The constant change and rising complexity of organizations, mainly due to the transforming nature of their business processes, has driven the increase of interest in business process management by organizations. It is recognized that knowing business processes can help to ensure that the software under development will meet the business needs. Some of software development processes (like unified process) already refer to business process modeling as a first effort in the software development process. A business process model usually is created under the supervision, clarification, approval, and validation of the business stakeholders. Thus, a business process model is a proper representation of the reality (as is or to be), having lots of useful information that can be used in the development of the software system that will support the business. The chapter uses the information existing in business process models to derive software models specially focused in generating a data model.- (undefined
