RESUMENEl trabajo examina críticamente la afirmación central de la hermenéutica de Paul Ricoeur, a saber, que el soporte material de la escritura es el rasgo determinante para que una secuencia discursiva sea considerada como un texto. La escritura cancela las condiciones fácticas de la enunciación y crea, de este modo, un ámbito de sentido estable en el que se puede validar una concepción de la subjetividad que está implicada en las dos estrategias de lecturas (el análisis estructural y la apropiación), esto es, un sujeto pasivo que se constituye por la idealidad del significado. Asimismo, el trabajo intentará precisar una serie de ambigüedades en el uso que Ricoeur hace del «ser en el mundo» para sostener la referencialidad del discurso.PALABRAS CLAVETEXTO, ESCRITURA, REFERENCIA, SUBJETIVIDAD, MUNDOABSTRACTThis paper critically examines the main assertion of Paul Ricoeur´s hermeneutics, i.e., that the material base of writing is the determining feature to consider a discursive sequence as a text. Writing cancels the factual conditions of enunciation and creates, in this way, a background of stable meaning where it is possible to validate a conception of subjectivity implicated in the two reading strategies (the structural analysis and the appropriation), i.e., a passive subject constituted by the ideality of meaning. Likewise, this paper aims to clarify some ambiguities in the way Ricoeur uses the «beings in the world» to support the discourse referentiality.KEY WORDSTEXT, WRITING, REFERENCE, SUBJECTIVITY, WORLD

The fourth generation cephalosporin antibacterial agent, cefepime, was loaded into layered double hydroxides for enhancing antibiotic efficiency, reducing side effects, as well as achieving the sustained release property. The intercalation of antibiotic into the inter-gallery of ZnAl-layered double hydroxide (LDH) was carried out using ion exchange method, by this constituting a nano-sized organic-inorganic hybrid material for a controlled release novel formulation. Although cefepime is a broad spectrum antibiotic, it has various adverse effects and a significant degradation rate. Thus, the preparation and physico-chemical characterization of nanomaterials able to intercalate this drug is an important study for medical and pharmaceutical field. The antibiotic inclusion into LDHs nanostructure was confirmed by advanced characterization techniques and the release profile of cefepime was analysed with the respect to pH of the simulated media.
