[eng] ISO standard 9001 is one of a set of management tools that libraries have adopted in recent years. This article focuses on libraries in higher education institutions that have received ISO certification of their quality management systems (ISO standard 9001:2000). We examine their reasons for seeking certification and the advantages and difficulties they have encountered in applying this ISO standard. Finally, we consider the future prospects of ISO standard 9001 in university libraries.

Els sistemes de gestió documental (SGD) són programes que permeten la creació i explotació de bases de dades documentals. Estan orientats a la gestió de documentació científica i tècnica (informació de tipus textual poc estructurada), en oposició als sistemes de gestió de bases de dades (SGDB) dirigits a la gestió de dades empresarials (informació de tipus factual molt estructurada). Es presenta una tipologia dels SGD, així com les característiques, tecnologia i estructura bàsiques d'aquests. Finalment, es comenten les noves tendéncies en tecnologia de sistemes documentals. S'adjunta també una relació dels principals SGD que poden trobar-se al mercat espanyol.

Se presenta la adaptación de un programa de gestión de aprendizaje (Moodle) a las necesidades de gestión de una intranet administrativa. Se describen los requisitos, su estructura y se analiza su grado de utilización cuatro años después de su puesta en marcha, indicando los principales puntos débiles del sistema y las posibles aplicaciones complementarias para contrarrestarlas.

Ante el gran incremento de información en el web, cada vez son más las empresas o instituciones que optan por implementar un sistema de gestión de contenidos, tanto en sus intranets como en la información que presentan a sus clientes o usuarios.

Las intranets o portales corporativos, gozan ya de una cierta trayectoria en las organizaciones grandes y medianas1, públicas2 y privadas, industriales y de servicios, y en esta nota queremos plantear algunas reflexiones destinadas a analizar si están contribuyendo a la mejora de la gestión de la información en las entidades donde se hallan implantadas.

La arquitectura de la información, partiendo de los sólidos principios clásicos dela ciencia de la información tradicional, nace hacia finales de los años 90. Es una disciplina encargada de estructurar, organizar y etiquetarlos elementos que conforman los entorno sin formacionales para facilitar la búsqueda yrecuperación de la información que contieneny mejorar, así, la utilidad y el aprovechamientode la misma por parte de sus usuarios. Entrelos principales sistemas o estructuras que conforman la anatomía arquitectónica de un sitio web destacan los sistemas de organización,de etiquetado, de navegación, de búsqueda y los vocabularios controlados. Respecto a su praxis, la elaboración de la anatomía arquitectónica de un sitio webse centra en los aspectos relacionados con las necesidades de sus usuarios tipo.

In the past decade, a number of trends have come together in the general sphere of computing that have profoundly affected libraries. The popularisation of the Internet, the appearance of open and interoperable systems, the improvements within graphics and multimedia, and the generalised installation of LANs are some of the events of the period. Taken together, the result has been that libraries have undergone an important functional change, representing the switch from simple information depositories to information disseminators. Integrated library management systems have not remained unaffected by this transformation and those that have not adapted to the new technological surroundings are now referred to as legacy systems. The article describes the characteristics of systems existing in today's market and outlines future trends that, according to various authors, include the disappearance of the integrated library management systems that have traditionally been sold.

Since the second half of the 1990s, knowledge management has taken shape and has been firmly consolidated as a new discipline within the realm of organisations. The principal objective of this work is to determine whether content management systems (CMS) can become the most appropriate technological standard for consolidating this field. The article describes and analyses the major functions (publishing and exploitation) of these new systems. It then examines the field of knowledge management ¿what are the different types of knowledge that we can find within an organisational context¿ and then identifies and analyses the operations critical to managing it appropriately. The article concludes by evaluating the extent to which technological solutions provided by CMS can assist in properly implementing these critical operations.

Soil properties are closely related with crop production and spite of the measures implemented, spatial variation has been repeatedly observed and described. Identifying and describing spatial variations of soil properties and their effects on crop yield can be a powerful decision-making tool in specific land management systems. The objective of this research was to characterize the spatial and temporal variations in crop yield and chemical and physical properties of a Rhodic Hapludox soil under no-tillage. The studied area of 3.42 ha had been cultivated since 1985 under no-tillage crop rotation in summer and winter. Yield and soil property were sampled in a regular 10 x 10 m grid, with 302 sample points. Yields of several crops were analyzed (soybean, maize, triticale, hyacinth bean and castor bean) as well as soil chemical (pH, Soil Organic Matter (SOM), P, Ca2+, Mg2+, H + Al, B, Fe, Mn, Zn, CEC, sum of bases (SB), and base saturation (V %)) and soil physical properties (saturated hydraulic conductivity, texture, density, total porosity, and mechanical penetration resistance). Data were analyzed using geostatistical analysis procedures and maps based on interpolation by kriging. Great variation in crop yields was observed in the years evaluated. The yield values in the Northern region of the study area were high in some years. Crop yields and some physical and soil chemical properties were spatially correlated.

No tillage systems significantly influence the soil system, but knowledge about the effects on the mineralogy of tropical and subtropical soils is limited. This study evaluated the long-term effects (26 years) of no-tillage (NT) on aluminum hydroxy-interlayered minerals of a subtropical Oxisol in Southern Brazil (Guarapuava, PR), compared to the same soil under conventional tillage (CT). The clay fraction (< 2 µm) in soil samples of the surface horizons of a field experiment under both management systems was analyzed by X-ray diffraction (XRD) to identify and characterize Al hydroxy-interlayered minerals before and after treatment with sodium citrate to remove intra-layer material. Soil liquid (solution) and solid phases were also characterized. The contents of total organic C, exchangeable cations, P, and the values of extractable acidity and cation exchange capacity as well as electrical conductivity and levels of dissolved organic C, basic cations, aluminum, Si, and sulfur in the soil solution were higher in the NT soil. Under both soil management systems, more than 90 % of the total soluble Al was complexed with organic compounds, with similar Al activity. No significant changes were detected by 2:1 clay mineral XRD analyses in terms of extension or intercalation of Al-hydroxy-polymers in the no-tilled in comparison to the conventionally tilled soil. In both soil management systems, Al and Si activities in the soil solution indicated thermodynamic stability of 2:1 clay minerals with partially occupied by hydroxy-Al, suggesting deceleration in the intercalation process and a tendency of transforming clay minerals from extensive into partial intercalation.
