Although there is technical information on the efficiency of advanced oxidation technologies (TAOs) at the laboratory level, in some cases at the pilot level and few on a large scale, it is not easy to select the most appropriate technology for an effluent, since the selection of technology depends on the characteristics of the contaminated water. Through the application of the multicriteria analysis technique, this article proposes a scale of TAOs for the complementary treatment of water contaminated with contaminants emergent (CE). The chosen alternatives were the technologies with peroxide (H2O2), Ozone (O3) and Fenton (Fe/H2O2) processes, the evaluation criteria were electric energy consumption (EEO), technological maturity level, complexity of design / operation and cost of operation. The technology most recommended by AHP is ozone and peroxide / UV with a difference of 8.6% in the frequency in the evaluation of the criteria. For the AHP-TOPSIS methodology, peroxide / UV is the key technology over ozone with a difference of 31.4% in the frequency of selection.

AVANZAR, Asociación Colombiana para el avance de la Investigación Clínica en Colombia, entidad sin ánimo de lucro que busca incentivar el desarrollo de la investigación clínica del país, llevo a cabo un estudio que tiene como propósito conocer la estructura y organización de los Comités de Ética en Investigación en el Territorio Nacional; como una de las actividades básicas de la Comisión de Ética en Investigación. El estudio permitirá obtener un diagnóstico situacional de los Comités de Ética en Investigación, con el fin de tomar las acciones respectivas para el crecimiento de los mismos y su nivelación de acuerdo con estándares internacionales que conlleven al desarrollo de esta disciplina. La información recolectada será utilizada de manera confidencial, para estimar los ponderados nacionales. ; The Colombian Association for the advance of the clinical research in Colombia (AVANZAR), is a non-profit entity that looks for the development of the clinical research in our country, this entity made an study that its proposals were to know the structure and organization of the ethical research Committees in Colombia ; this study is one of the basic activities of The Research Ethical Commission. This study allows us to know a situational diagnostic about the Research Ethical Committees, in order to make the corresponding actions for the growth of them, and reach their level under the international standards, that let the development of this discipline. The information that we recollected will be use in a confidential way in order to estimate the national standards.
