Aquest estudi representa la primera exploració de l'ús de la televisió i la selecció de programes per part de grups d'indígenes a Chiapas. Més concretament, s'examina com els membres d'aquests grups seleccionen canals i programes específics dels mitjans de comunicació per raons d'etnicitat, i com això té a veure amb estratègies de mobilitat social. Les dades de 173 indígenes estudiants de la universitat Intercultural de Chiapas van indicar que per a 77 membres d'aquesta mostra, veure la televisió i seleccionar programes sobre la base de la seva etnicitat és una activitat de visualització important per a la seva autoestima etnolingüística. Aquests resultats es discuteixen en termes de la representació televisiva dels grups ètnics de Chiapas i motiven la realització de futures investigacions sobre aquests temes a Chiapas.

Aquest estudi analitza els usos de les TIC a l'administració autonòmica catalana. De forma més específica, l'estudi se centra en la interacció entre l'ús d'un vessant concret de les TIC, la xarxa Internet, per part de l'administració pública, i determinats aspectes centrals d'aquest tipus d'institucions: la seva organització i estructura internes, la provisió de serveis públics o la relació amb altres agents socials. Hem analitzat, doncs, el fenomen del govern electrònic en el marc particular de la Generalitat de Catalunya, estudiant-ne el grau de desenvolupament i penetració, les seves característiques més remarcables i els problemes més importants que s'hi plantegen. El projecte de recerca es concreta en un estudi de cas sobre un projecte d'innovació específic però de gran abast, que es trobava en el moment de realització de l'estudi en la seva primera fase d'implementació: el projecte Administració Oberta de Catalunya (AOC). Concretament ens hem centrat en el vessant d'aquesta iniciativa pública que es concretava en la creació d'un portal interadministratiu a Internet, el portal www.cat365.net, destinat a proveir electrònicament serveis públics de totes les administracions que operen a Catalunya. L'estudi analitza les transformacions internes de l'administració que s'hi poden trobar associades i els elements que les condicionen, tant positivament com negativa. Igualment, intentem analitzem el que aquestes transformacions poden suposar per a la relació entre els ciutadans i les institucions públiques.

The Final Year Project consists of two essentially different parts, which share acommon theme: HTML code validation. The first of these two parts focuses on the study of the validation process. It supplies a brief introduction to the evolution of HTML and XHTML, the new tags introduced in HTML5 and the most common errors found in today's websites. Already developed HTML validation tools are analyzed and examined in detail in order to compare their features and evaluate their performances. Lastly, a comparison of the parsing process in the most common browsers found nowadays is provided. In the second part of the project the focus of the project is shifted towards the development of a XHTML5 validation tool. The input is a XHTML5 file whose content may or may not comply with the W3C specification, and therefore, may or may not be a valid XHTML5 document. The output provided by this tool will be a fixed XHTML5 document and an error log returned in the form of a XML file. Information as to the course of action pursued to fix the error and its location will also be included.

L’objectiu d’aquest projecte és analitzar la qualitat literària dels best sellers i observar les limitacions d’aquest anàlisi. Deguda la complexitat del fenòmen best seller, i tot i ser conscients de que són obres que s’han d’abordar des d’una perspectiva pluridisciplinar, vam decidir començar aquest projecte analitzant tres best sellers espanyols des de la metodologia de l’estilística i de la narratologia. Les obres analitzades són 'La sombra del viento' de Carlos Ruiz Zafón, 'Un milagro en equilibrio', de Lucía Etxevarría, i 'El capitán Alatriste', de Pérez Reverte, i l’anàlisi és de tipus quantitatiu, de les estructures emprades per a l’expressió de lo metafòric, dels personatges, trames i tòpics. Les conclusions varen ser que, des d’un punt de vista estilístic, es pot demostrar la mala qualitat literària d’aquestes obres, així com la seva relació amb la tradició del gènere del folletí, amb el que comparteixen moltes característiques. Tanmateix, una altra de les conclusions de l’estudi fou que abordar el best seller des de l’estilística no ofereix una visió completa d’aquest fenòmen. Aquest projecte doncs, que té per títol “Estudio estilístico de tres casos de best seller en el ámbito español: 'La sombra del viento', 'Un milagro en equilibrio' y 'El capitán Alatriste'” ha d’ampliar-se en catàleg i en metodologia, adoptant vàries perspectives simultàneament, que ofereixin una visió adecuada de la complexitat del fenòmen. El catàleg s’ha extès a 15 obres en l’àmbit espanyol, i a 15 més en l’àmbit francès, durant el 2008, i la perspectiva multidisciplinar engloba estudis culturals, de recepció i sociologia. Des d’aquesta nova base metodològica i teòrica, s’han realitzat 500 enquestes a lectors a Barcelona i a París, en diferents punts de venta de llibres, durant el 2010.

Patients with intestinal failure who receive HPN are at high risk of developing MBD. The origin of this bone alteration is multifactorial and depends greatly on the underlying disease for which the nutritional support is required. Data on the prevalence of this disease in our environment is lacking, so NADYA-SEMPE group has sponsored this transversal study with the aim of knowing the actual MBD prevalence. MATERIAL AND METHODS: Retrospective data from 51 patients from 13 hospitals were collected. The questionnaire included demographic data as well as the most clinically relevant for MBD data. Laboratory data (calciuria, PTH, 25 -OH -vitamin D) and the results from the first and last bone densitometry were also registered. RESULTS: Bone mineral density had only been assessed by densitometry in 21 patients at the moment HPN was started. Bone quality is already altered before HPN in a significant percentage of cases (52%). After a mean follow up of 6 years, this percentage increases up to 81%. Due to retrospective nature of the study and the low number of subjects included it has not been possible to determine the role that HPN plays in MBD etiology. Only 35% of patients have vitamin D levels above the recommended limits and the majority of them is not on specific supplementation. CONCLUSIONS: HPN is associated with very high risk of MBD, therefore, management protocols that can lead to early detection of the problem as well as guiding for follow up and treatment of these patients are needed.

BACKGROUND. Maternal genetics and feeding before and during pregnancy, different maternal metabolic pathologies, as well as nutrient intakes of newborns in their first months of life may be involved in the obesity aetiology and its long-term consequences. The possible role of these and others factors, the mechanisms and the effects on the metabolism, and the development of this disease need further research. OBJECTIVE. To acquire more knowledge about foetal adipose tissue development and the influence of genetic, dietetic and environmental factors on the risk to suffer from obesity. METHODOLOGY. Four study groups have been established with 30 pregnant women in each one: 1) control group; 2) mothers with glucose intolerance/gestational diabetes; 3) women with low weight gain during pregnancy, and 4) women with overweight/obesity at the beginning of the pregnancy. The magnitudes to be studied are: 1) dietary intake; 2) life-style habits; 3) physical activity; 4) anthropometry and body composition; 5) haematological study; 6) biochemical study (lipid and metabolic biomarkers); 7) immune function profile related to nutritional status; 8) psychological profile; 9) genetic biomarkers, and 10) microbiological markers; all of them in relation to the development of the foetal adipose tissue in the first stages of life and the risk of suffering from obesity in the future. CONCLUSION. This project, coordinated by the Department of Paediatrics of the School of Medicine in the University of Granada, and with the collaboration of well-known and expert research groups, tries to contribute to the knowledge about the obesity aetiology in infancy and its subsequent development in later periods of life.

La reutilización de las aguas residuales es una parte esencial del uso sostenible del agua. Sin embargo, las actuales plantas de tratamiento no están preparadas para tratar determinados compuestos como los llamados “contaminantes emergentes”. Los hábitos de consumo actuales estan generando una serie de residuos o microcontaminantes que hace tan solo unos años no existian. Entre esas nuevas sustancias aparecen los PPCP’s (Pharmaceuticals & Personal Care Products) que son un amplio grupo de compuestos químicos utilizados en veterinaria, prácticas agrícolas, salut humana y cosmetología. El mayor problema que presentan estas substancias en la actualidad es el parcial desconocimiento sobre sus efectos, la ausencia de reglamentaciones que determinen las concentraciones máximas admisibles en los cauces de vertido, la reducción en procesos de depuración convencionales, así como los tratamientos específicos aplicables a su eliminación. Los objetivos del presente proyecto són: estudiar las tipologías de PPCP’s y sus influencias para la salud humana y el medio ambiente, estudiar los diferentes sistemas de tratamiento de aguas existentes en plantas depuradoras y evaluar su eficiencia en la depuración de PPCP

Chronic renal failure is commonly related to hyponutrition, affecting approximately on third of patients with advanced renal failure. We carried out a longitudinal study to assess nutritional evolution of 73 patients on a regular hemodialysis program, assessing changes in the anthropometrical parameter body mass index (BMI) and its correspondence to biochemical nutritional parameters such as total protein (TP) levels and serum albumin (Alb). Every three months plasma TP and albumin levels were collected and BMI was calculated by the standard formula: post-dialysis weight in kg/height in m2. For classifying by BMI categories, overweight and low weight were defined according to the WHO Expert Committee. Studied patients had a mean age of 53 years, 43 were male and 30 were female patients. BMI in women was lower than that in men (p < 0.001), as well as TP (p < 0.001) and Alb (p < 0.001) levels. Mean BMI was 29.3 kg/m2. Three point two percent of the determinations showed low weight, 12.16% overweight, and 83.97% normal BMI. TP were normal in 90.76% and decreased in 9.24%. Alb was normal in 82.2% and low in 17.78%. After the follow-up time (21.6 months, minimum 18 months, maximum 53 months), the Kruskal-Wallis test did not show a statistically significant change for BMI but it did show a change for the biochemical parameters albumin and total proteins (p < 0.05): nutritional impairment in CRF patients is manifested on biochemical parameters (TP and Alb) with no reflection on anthropometrical data.

OBJECTIVE To assess the scientific activity and information production of the journal Nutrición Hospitalaria, for the period 2001-2005 by means of a Bibliometric study. METHOD Cross-sectional descriptive study of the results obtained from the analysis of the articles published in the journal Nutrición Hospitalaria. The data were obtained by consulting the electronic version through the Web. In those cases in which there was a link breakdown, and thus, the inability to have access to the electronic document the printed version was consulted. All the documental possibilities were taken into account with the exception of communications to congresses. RESULTS A total of 345 articles were published, 187 (54.20%) being original articles. The geographical distribution of the first author was Spanish in 287 articles (83.19%) and Latin American in 27 (7.83%). Most of the articles are from health care centers (172 articles (49.86%)), and the cooperation index being 4.15. Madrid is the most productive province, for both the absolute and adjusted frequencies. The median number of references per article is 18, the mean being 23.52 (95% CI 20.93 - 26.10). The predominant language was Spanish, with 308 articles (89.28%). CONCLUSION Nutrición Hospitalaria may be considered as a reference journal regarding information and scientific communication on Nutrition for both the Spanish and Latin American communities. The bibliometric parameters studied compare with those verified for the remaining top of the list Spanish scientific journals on health sciences.

OBJECTIVE To describe and assess the consumption of the information consulted and cited in the articles published in the journal Nutrición Hospitalaria for the period 2001--2005 by means of bibliometric analysis. METHOD Cross-sectional descriptive analysis of the results obtained from the analysis of the lists of bibliographic references of the articles published at Nutrición Hospitalaria. We studied the most cited journals, the signatures index, the type of document referred, the publication language, the distribution of geographical origin, and obsolescence and readiness index. We took into account all types of documents with the exception of Communications to Congresses. RESULTS 345 articles were published at Nutr Hosp, containing 8,113 bibliographic references, with a median of 18, a maximum of 136 and minimum of 0 BR per article. The mean (rate of publications per published article during the specified period) is 23.52 (95% IC 20.93-26.10) and the mean at 5% is 20.66 per article. The 25th and 75th percentiles are 6 and 32, respectively, the interquartile interval being 26 BR per document. The semi-period of Burton and Kebler is 7 years and the Price Index is 38.18%. CONCLUSION The bibliographic references, the consumption of information, of the articles published at Nutrición Hospitalaria present parameters similar to other journals on health science. However, good data on obsolescence are observed, which reveal the good validity of most of the references studied.
