Raquel Iniesta,Susana Ochoa,Judith Usall
Schizophrenia Research and Treatment , 2012, DOI: 10.1155/2012/365452
Abstract: Objective. The main objective is to analyze the use of mental health services in a sample of people with schizophrenia and other psychoses according to gender. Method. The sample of this observational and retrospective study (=7483) consisted of all the persons who visited any mental health service of the Parc Sanitari Sant Joan de Déu from 2001 to 2007 with a diagnosis of schizophrenia and other psychoses. The main measures analyzed regarding gender were the frequency of patients for each diagnosis, their risk of being admitted into hospital, and the number and length of hospitalizations for the subsample of inpatient people during the study period. Results. Men are more frequent in the total sample (58.1%). For diagnosis of schizoaffective or delusional disorder, women have a higher frequency than men. Women with diagnosis of schizophrenia have a lower risk of being admitted to the hospital (RR=0.84, 95% CI (0.72, 0.97)). We found a higher risk of longer stays for men with schizophrenia of the disorganized type (RR=0.49, 95% CI (0.30, 0.81)), undifferentiated (RR=0.41, 95% CI (0.27, 0.61)), or delusional disorder (RR=0.65, 95% CI (0.49, 0.87)). Conclusion. Gender of patients is a relevant variable in mental health service use by patients with schizophrenia and other psychoses.

Revista de la Asociación Espa?ola de Neuropsiquiatría , 2005,
Abstract: Las autoras exponen en este artículo los resultados de una investigación realizada en dos centros de Salud Mental Infantojuvenil de Catalu a, sobre la realización de trabajo en red profesional en las consultas ambulatorias. El estudio recoge las actuaciones efectuadas en los casos seleccionados, haciendo una distinción entre el trabajo de atención directo con el paciente y su familia y el trabajo indirecto con los profesionales. Se pretende estudiar el tipo de relación entre la cantidad de trabajo entre profesionales y el diagnóstico del paciente, la tipología familiar, el género y las características propias de cada centro de atención. Una segunda intención es conocer las características del TRP (trabajo en red profesional) en cuanto al tiempo utilizado, formas de contacto y tipos de relación entre profesionales. Se hace una distinción conceptual sobre lo que es la coordinación y el trabajo en red profesional o trabajo indirecto, definiendo éste como la intervención que surge a consecuencia de las propias necesidades de cada caso. El estudio pone especial énfasis en resaltar cómo en la atención a ni os y jóvenes existe una gran inversión del tiempo profesional dedicada al trabajo indirecto y cómo éste, en muchas ocasiones, es uno de los pilares fundamentales que permitirá el abordaje del trabajo con la familia y el paciente, facilitando una relación funcional entre servicios y familia.

Conclusion. Gender of patients is a relevant variable in mental health service use by patients with schizophrenia and other psychoses. 1. Introduction Gender differences in schizophrenia have received widespread empirical support with respect to incidence, age at onset, familial transmission, and neurobiological factors [1, 2]. However, gender differences in the use of mental health services have been less studied, and the results are controversial. The most studied variables are number of hospitalizations and length of hospital stay. Some researchers have found a higher number of hospitalizations and length of stays in men than women [3–5]. However, Lindamer et al. [6] found that women with schizophrenia have a higher risk of being hospitalized than men. Specifically, gender differences in the use of services with regard to the different subtypes of schizophrenia have been less explored. Beratis et al. [7] found that the frequency of men was more than three times greater than that of women in the residual and the catatonic subtypes. Tang et al. [8], using the ICD-10 classification system, found differences in the overall subtype distribution between male and female patients, with the paranoid subtype being more common in females; however, they did not explore hospitalizations regarding the subtypes of schizophrenia. On the other hand, Mimica et al. [9] found a different hospitalization pattern between subtypes of schizophrenia; the

Abstract: we use gis to determine changes and variation in the distribution of various vegetation types and land use from 1990 to 2000 in centlas marshes biosphere reserve, in tabasco, mexico. maps of geology, soils, hidrology, temperature, rain, human settlements and roads were created for the area in order to see the influence of the environmental conditions that could affect vegetation. the landsat mss images for 1992 and for the year 2000 landsat etm images were used and classified using chuvieco's mixed classification method (1995). vegetation and land use maps were generated for the year 1990 and 2000 using verification field points. the gis analysis generated a change map and variation matrix. the tropical forest was the most affected ecosystem by diminishing considerably its surface. the change rate for the tropical forest in association of bucida buceras represent 6.6% and for tropical forest association of haematoxylon campechianum there was a 34.96% change rate. the change rate for mangrove was 1.15%, 0.72% for swamp communities and 27.82% for grassland. the analysis indicates that the change rate is mostly associated with the presence of roads, human settlements and channels mostly. the swamp communities, grasslands and water changed its distribution from they're original soils and geology units. the fires registered each year and speciallly those that ocurred in 1998, road building, petroleum extraction, overuse of natural resources, presence of cattle, wood consumption and the use of fire for hunting are some of the causes for the loss of tropical rain forest and the increased establishment of swamp communities.

Revista de Ingeniería , 2010,
Abstract: La operación de redes de distribución de agua potable involucra dos asuntos con grandes repercusiones económicas: la renovación y rehabilitación de tuberías, y la reducción del índice de Agua No Contabilizada (IANC). Este trabajo presenta un algoritmo que, con base en el concepto de potencia unitaria, permite priorizar los tubos por renovar, de tal modo que se reduzca la potencia disipada y el IANC, se mantenga el plano de presiones nivelado y se encuentre la situación ideal para realizar la renovación en términos de beneficios económicos. Se presentan dos casos de estudio en los cuales la metodología propuesta probó ser eficiente al hallar esquemas de renovación rentables e hidráulicamente óptimos.Water Distribution System operation involves two issues that have large economic repercussions: pipe renewal and rehabilitation and reduction of Non-Revenue Water (NRW). This paper presents an algorithm that, based on the unitary power concept, selects the most important pipes to be replaced in order to reduce the dissipated power and the NRW, while keeping the pressure surface levelled. Additionally, the proposed methodology finds an ideal renewal scheme in terms of economic benefits and profitability. This paper includes two case studies in which the proposed methodology proved to be successful, achieving renewal schemes both profitable and hydraulically optimum.

Abstract: El estudio se realizó en el Parque Educativo Laguna Bélgica (PELB). El objetivo fue el de caracterizar las asociaciones vegetales para sentar las bases para su manejo y conservación. El mapa de vegetación se realizó con la interpretación de ortofotos, verificaciones de campo y un Sistema de Información geográfica. La caracterización de la vegetación y los inventarios de flora le osa se elaboraron según el método de Mueller-Dombois y Ellenberg. Se censaron todas las le osas con altura > 1 m y diámetro a la altura del pecho > 3 cm. La cobertura se evaluó cualitativamente. Se reconocieron 5 asociaciones vegetales: encinar de Quercus oleoides, encinar de Q. elliptica, acahual arbóreo, pastizal y asociación secundaria de herbáceas. En la zona de estudio se colectaron 159 especies, las cuales se complementaron mediante revisión bibliográfica obteniéndose un total de 254 especies, comprendidas en 157 géneros y 64 familias. Se aportan 68 nuevos registros para el PELB. La flora de Laguna Bélgica presenta una mayor afinidad florística con los bosques húmedos de la vertiente del golfo que con los de la depresión central. Se resalta la alta diversidad florística y la importancia por conservar y manejar este relicto de vegetación. The study was conducted in the Parque Educativo Laguna Bélgica (PELB).

Abstract: Se identificó y cuantificó la variación espacial de los tipos de vegetación y usos del suelo en la Reserva de la Biosfera Pantanos de Centla, Tabasco durante 1990 y 2000. Se generaron bases geográficas digitales referentes a geología, edafología, hidrología, temperaturas mínimas, temperaturas máximas, precipitación, vías de comunicación y localidades. La información fue almacenada en un sistema de información geográfica. Se clasificaron escenas del satélite Landsat MSS de 1992 y Landsat ETM del 2000. Se generaron mapas de vegetación y uso del suelo para 1990 y 2000 basados en puntos de verificación. Los mapas generados fueron sobrepuestos para obtener un mapa de cambios y una matriz de variación. Las tasas de cambio por pérdida anual se estimaron en 6.06% (selva de puckté) y 34.96% (selva de tinto); en tanto que la tasa de incremento anual fue de 1.15% (manglar), 0.72% (comunidades de hidrófitas) y 27.82% (pastizal). Los cambios encontrados se relacionaron con la presencia de carreteras pavimentadas, localidades y canales, siendo éstos últimos los que más afectaron. Los resultados muestran que las comunidades de hidrófitas, pastizales y cuerpos de agua se desplazaron a todas las unidades de suelo y geología. Los cambios encontrados pueden atribuirse a diversas causas: los incendios, apertura de vías de comunicación, actividades petroleras, sobreexplotación de recursos, expansión ganadera, tala para extracción de madera y quema intencional para captura de especies.
