Towars a chemical reagents and residues management at the teaching laboratories of the Chemistry School of the Universidad Nacional

The academic activities carried out at the School of Chemistry make indispensable to develop actions oriented toward the consolidation of a reagent and residue management system, especially in the teaching laboratories. The project “Management of reagents and residues in the teaching laboratories of the School of Chemistry” works under the Green Chemistry values which designs products and chemical processes that reduce or eliminate the use and production of dangerous substances, to benefit the environment. With a preventive vision, a change from the  laboratory practices is looked to select those with less environmental impact. Additionally, residue quantification is made and its management protocols are developed for each practice. The project has several stages: diagnose, action implementation, student, teacher and administration personnel training and evaluation during the process and at the end of it. The article describes methodological aspects of the project operation emphasizing on reagent and residue quantification through flow diagrams.

EXPERIENCIA MUNICIPAL EN EL USO E IMPLEMENTACIÓN DE UN SISTEMA DE INFORMACIÓN TERRITORIAL

En el Área Metropolitana de San José (AMSJ), 14 Municipalidades se esfuerzan por realizar mejoras sustanciales en la administración de los territorios, la gestión de cobro de impuestos y servicios y el desarrollo de planes de Ordenamiento Territorial Local (Planes Reguladores). Dentro de este ámbito,  la  implementación de un Sistema de Información Territorial (SIT), cobra especial relevancia, por lo que la Municipalidad de Escazú, ha desarrollado proyectos que le han permitido contestar preguntas cruciales en torno de la implementación de un SIT, entre ellas, ¿Por qué se necesita un SIT en la Municipalidad?, ¿Cómo implementarlo?, ¿Se debe ajustar el SIT a la Municipalidad o esta última debe ajustarse al SIT?, ¿Cuánto cuesta y cuánto se tarda para tener un SIT?. El proceso no ha sido fácil, y probablemente el camino para implementar con éxito un SIT no sea único o idéntico para todas las organizaciones, sin embargo, todo aquello que haya sido utilizado y probado puede ser de utilidad para otros.Palabras clave: Gestión municipal, Sistema de  Información Territorial, Sistema de  información Geográfca, Sistema de Información Catastral, Planifcación urbana, Formulación de proyectos.Abstract At Área Metropolitana de San José (AMSJ), 14 municipalities are making efforts to improve their systems for taxes collection and Urban Land Planning in order to achieve sustainable development of their territories. At this stage, implementation of a Geographical Information System (GIS) or Territorial Information System (SIT, in Spanish) takes on special relevance. The city of Escazú has developed projects that have allowed it in turn to answer crucial questions concerning implementation of a SIT, such as: Why is it necessary for a municipality to have a SIT? How does it work? Does the organization have to adjust to the SIT or should the SIT be adjusted to the needs of the organization? Finally, how much does it cost to implement a SIT and how long will it take? The process has not been easy, and probably the way to implement a successful SIT is not the same for every municipality. Nevertheless, the experiences of one municipality can be useful for others seeking to implement such a system.
