Abstract: The Women and Science Committee was set up in 2002 as an advisory unit on gender issues to the Presidency of the Spanish National Research Council (CSIC). During these ten years of existence, the committee has helped to improve the scientific careers of women in the CSIC and at the same time promoted the visibility of their scientific contributions. The history, objectives and activities of the Women and Science Committee during these years are reported here. The main gender policies and legal-framework changes at European and Spanish levels are recapped. Specifically, the sex distribution of permanent staff scientists in 2003 and 2012 are analysed and compared. The sex-disaggregated data by fields of knowledge show an improvement on the number and rank of female researchers in recent years, although they are still far from balanced. There is a bigger shortage of women in certain fields and at the top of the professional ladder. The implementation and monitoring of gender equality policies is still needed in order to approach a gender-balanced situation. This, in turn, will contribute to the excellence of the results of the CSIC′s research activities. La Comisión Mujeres y Ciencia del Consejo Superior de Investigaciones Científicas (CSIC) fue creada en 2002 como comisión asesora de la Presidencia para temas de género. En sus diez a os de funcionamiento, la comisión ha contribuido a mejorar la carrera científica de las mujeres investigadoras del CSIC y a aumentar la visibilidad de los resultados de sus investigaciones. En este trabajo se resumen los orígenes y objetivos de esta comisión, así como las actividades realizadas desde 2002, y se analiza la historia de la plantilla investigadora en ese periodo. Se recogen, también, los cambios producidos desde 2005 en la legislación espa ola y europea en materia de igualdad de género. Al analizar específicamente los datos de la situación de las mujeres en 2003 y en 2012 desagregados por áreas de conocimiento, se muestra un avance en la proporción de mujeres en casi todas las áreas pero se está aún lejos del objetivo de paridad. El déficit en la presencia de mujeres es mayor en ciertas áreas y en el nivel profesional más alto, por lo que siguen siendo necesarias medidas activas para promover la igualdad, lo que a su vez contribuirá a la excelencia en las actividades científicas del CSIC.
Co-occurrence matrix and fractal dimension for image segmentation
Marrón,Beatriz S;
Revista de Matemática Teoría y Aplicaciones , 2012,
Abstract: one of the most important tasks in image processing problem and machine vision is object recognition, and the success of many proposed methods relies on a suitable choice of algorithm for the segmentation of an image. this paper focuses on how to apply texture operators based on the concept of fractal dimension and cooccurence matrix, to the problem of object recognition and a new method based on fractal dimension is introduced. several images, in which the re- sult of the segmentation can be shown, are used to illustrate the use of each method and a comparative study of each operator is made

Revista de Matemática Teoría y Aplicaciones , 2012,
Abstract: Una de las tareas más importantes en el procesamiento de imágenes es el reconocimiento de objetos, y el éxito de muchos de los métodos propuestos se basa en la adecuada elección del algoritmo para la segmentación de la imagen. Este trabajo se enfoca en cómo aplicar los operadores de textura basados en los conceptos de dimensión fractal y de matrices de co-occurencia, al problema de reconocimiento de objetos y se introduce un nuevo método basado en la dimensión fractal. Para ilustrar cada método se utilizan imágenes en las que se muestra el resultado de la segmentación y se realiza un estudio comparativo de cada operador One of the most important tasks in image processing problem and machine vision is object recognition, and the success of many proposed methods relies on a suitable choice of algorithm for the segmentation of an image. This paper focuses on how to apply texture operators based on the concept of fractal dimension and cooccurence matrix, to the problem of object recognition and a new method based on fractal dimension is introduced.

Texture Filters and Fractal Dimension on Image Segmentation  [PDF]
Beatriz Marrón
Journal of Signal and Information Processing (JSIP) , 2018, DOI: 10.4236/jsip.2018.93014
Abstract: Texture analysis is important in several image segmentation and classification problems. Different image textures manifest themselves by dissimilarity in both the property values and the spatial interrelationships of their component texture primitives. We use this fact in a texture discrimination system. This paper focuses on how to apply texture operators based on co-occurrence matrix, texture filters and fractal dimension to the problem of object recognition and image segmentation.
La informatización en urgencias y emergencias
Busca,P.; Marrón,R.;
Anales del Sistema Sanitario de Navarra , 2010, DOI: 10.4321/S1137-66272010000200009
Abstract: the health services are undergoing a significant transformation due to information and communications technologies (ict). computerized clinical history in hospital emergency department (ed) is improving care in this area of medicine, increasing the security of the information, access to it and favoring the implementation of clinical management. in this aspect, the eds present certain distinctive characteristics, such as management of care times, secure management of care areas and rapid acquisition of relevant information on the patient. while there is unanimity on the advantages of incorporating the electronic history into the eds, there is also unanimity on the difficulties involved in implementing these systems. human factor is one of the most relevant when it comes to handling the management of the changeover to computerization. to minimize the impact there must be support for the professionals and the applications developed must be integrated into the electronic clinical history of the patient and offer useful functional applications for users and patients. the automatization of repetitive tasks, the use of forms and protocols, the implementation of messages that help in decision making and the system of clinical security are essential in computer applications. the structure and planning of information must be adjusted to the structure and needs of the eds. the computer applications must be adapted to the functional structure of today's eds, providing information in real time about the care situation and gathering information to generate indicators that will make it possible to evaluate and improve the different areas of work: triage, boxes, observation rooms, critical units. management of information, which these systems provide us with, will make it possible to determine and compare the casuistry and case mix of the eds. in short, for a computer application to be capable of dealing with the complexity of an ed, it must incorporate three elements: operations i

La informatización en urgencias y emergencias Computerization in urgency and emergency care
P. Busca,R. Marrón
Anales del Sistema Sanitario de Navarra , 2010,
Abstract: Los servicios sanitarios están sufriendo una importante transformación de la mano de las tecnologías de la información y comunicación (TIC). La historia clínica informatizada en los servicios de urgencias hospitalarios (SUH) está mejorando la asistencia en este ámbito de la medicina, incrementando la seguridad de la información, el acceso a la misma y favoreciendo la implantación de la gestión clínica. En este aspecto, los SUH presentan algunas características distintivas propias como la gestión de los tiempos asistenciales, la gestión segura de las áreas asistenciales y la adquisición rápida de información relevante del paciente. Aunque existe unanimidad sobre las ventajas de la incorporación de la historia electrónica a los SUH, también la hay sobre las dificultades de implantación de estos sistemas. El factor humano es uno de los más relevantes a la hora de manejar la gestión del cambio hacia la informatización. Para minimizar el impacto debe existir apoyo a los profesionales y las aplicaciones que se desarrollen deben integrarse con el historial clínico electrónico del paciente y ofrecer funcionalidades útiles para los usuarios y los pacientes. La automatización de tareas repetitivas, la utilización de formularios y protocolos, la implementación de mensajes que ayuden en la toma de decisiones y los sistemas de seguridad clínica deben estar muy presentes en los aplicativos informáticos. La estructura y ordenación de la información debe adecuarse a la estructura y necesidades de los SUH. Los aplicativos informáticos tienen que adaptarse a la estructura funcional de los SUH actuales dando información en tiempo real de la situación asistencial y recogiendo información para generar los indicadores que permitirán evaluar y mejorar las diferentes áreas de trabajo: triaje, boxes, salas de observación, unidades de críticos. La gestión de la información, que nos proporcionan estos sistemas, va a permitir conocer y comparar casuística o casemix de los SUH. En definitiva, para que un aplicativo informático sea capaz de abordar la complejidad de un SUH debe contemplar tres puntos de vista: las operaciones dentro y fuera del servicio, aplicar interfaces de usuario intuitivas y multiusuario y poder realizar una buena gestión de datos tanto a nivel macro, meso y micro. The health services are undergoing a significant transformation due to information and communications technologies (ICT). Computerized clinical history in hospital emergency department (ED) is improving care in this area of medicine, increasing the security of the information, access to it and favorin
Properties of the Estimators for the Effective Bandwidth in a Generalized Markov Fluid Model  [PDF]
José Bavio, Beatriz Marrón
Open Journal of Statistics (OJS) , 2018, DOI: 10.4236/ojs.2018.81006
Abstract: The Generalized Markov Fluid Model (GMFM), introduced in [1], is assumed for modeling sources in the network because it is versatile to describe the traffic fluctuations. In order to estimate resources allocations or in other words the channel occupation of each source, the concept of effective bandwidth proposed by Kelly [2] is used. In this paper, we present a formula for calculating the effective bandwidth, developed for the Generalized Markovian Flow model, which is of particular interest because it allows expressing said magnitude depending on the parameters of the model. We present unbiased estimators for these parameters that can be obtained from real data. The convergence and the consistency of the estimation are studied, and confidence bands are found. Illustrative calculation and performance of the proposed estimators were tested with simulated data and ideal results were obtained.
APPROACH TO THE CONCEPT OF SCALE IN THE EARLY YEARS OF PRIMARY EDUCATION. PRESENTATION OF A GAME TO WORK THIS CONCEPT FROM ACTIVE TEACHING
María Jesús Marrón Gaite
Didáctica Geográfica , 2012,
Abstract: The main objective of the present paper is to introduce a didactic play designed in order to help the students of early years of primary education the understanding of the concept of scale. The understanding of this concept prepare them to the correct interpretation, in further years, of this conventionalism in plans and maps. Empirical research we have conducted on the effectiveness of this material, testing in schools in the city of Madrid, has shown a high degree of usefulness for teaching and learning the subject. The use of this material in the classroom has been done from active teaching, giving a central role to the ludic methodology, and has allowed the achievement of meaningful learning by the students from their previous ideas and conceptual representations.
