Así, esta investigación da cuenta de aquellos aspectos del proceso de enseñanza que los estudiantes aplican a los alumnos en el liceo y que son correspondientes y coincidentes con el proceso de formación recibido en la UCSC. Para ello se diseña y aplica un dispositivo de formación fundamentado en la teoría de situaciones didácticas de Brousseau. La utilización de este dispositivo en el liceo por parte del estudiante permite observar la influencia de la formación inicial sobre el desarrollo de competencias matemáticas en los estudiantes

There are several online and offline tools to support the manual web accessibility evaluation process. However, they all have some weaknesses because none of them includes all the desired features. In this paper we present Hera-FFX, an add-on for the Firefox web browser that supports semi-automatic web accessibility evaluation.

The aims of reconstruction are the preservation of renal function and achievement of urinary continence. Considerable controversy exists on the subjects of bladder augmentation, procedures to increase outlet resistance, and continent stomas. The authors put the most recently published information in perspective in the light of their own personal experience. Recent findings Thirty-seven papers covering the above-mentioned subjects published in the past 5 years (25 of them published since 2000) have been selected. Seven relevant older references are included. There is persistent interest in developing methods to enlarge the urinary bladder that avoid bringing the urine in contact with the intestinal mucosa. The artificial urinary sphincter and fascial slings are the most frequently reported methods to increase outlet resistance. The Mitrofanoff principle continues to be regarded as an effective method to construct a continent catheterizable channel, either with the appendix or reconfigured intestinal segments. The achievement of fecal continence has to be pursued in parallel with urinary continence. Incontinent diversions continue to be best for a small group of patients. The role of continent urinary diversion requires reassessment. Summary Progress in this area continues to be made. Periodic, critical and objective reviews on the subject should help the practitioner to arrive at sound decisions.
