The use of virtual media as a support to formal higher education requires a methodology able to support the teacher's specific educative needs and the pedagogical requirements of diverse subjects and knowledge areas. This paper presents the methodology used on the construction of Learning Virtual Environments as a complement to the face to face activities of ten different disciplines courses on the Universidad de los Andes, at Bogotá (Colombia). The procedure and balance of this methodology are part of the reflection contained in this document. [ABSTRACT FROM AUTHOR]

This article explores, through a teenager guerrilla member's life story, the problem of encounters and the migrant's face as representative expressions of the urban, and of cruelty in general. Using a narrative where alternative images of the war in the mountains appear, and a travel through Bogota streets, this images' meeting is analyzed as a face or as a profane illumination, using Walter Benjamin and Emmanuel Levinas' works. That which cannot be defined in an encounter, as in a face, and that which applies to the way we understand the problem of identity in the city, can only be compared with the surrealist experience of encounters and disencounters between Nadja and André Breton, similar also to the anthropological experience of facing object consumption and the look over things while we walk on the streets and descend from buses that bring us for the first time to the city. This essay is a shorter version of a paper I wrote for the Symposium "Cruel sceneries: esthetics and signs of trance and violence in Puerto Rico and Colombia" that took place in San Juan de Puerto Rico in April 2001. I thank Manuel Hernández Benavides for his reading and suggestions to a previous version of this article. [ABSTRACT FROM AUTHOR]

Convective activity prediction in the tropics are still an unsolved problem. Difficulties are mainly related to the fact the phenomenum, very often results as a complex interaction between local and large scale stream conditions. Days with thunderstorm activity compared with surface and height data for 10 years are presented in this paper in order to determine both, large and local scale conditions that propitiate the developing of convective activity in the Bogota sabana. As a main result it is shown that at the 700 hPa isobaric surface, electrical storms appears whit weale winds and high contents of humidity, which characterize the alisios convergence zone and also the ecuatorial ascendent branch of the Hadley cell. Besides, the analysis shows that local thermal convection strengthened by orograhapic effect are the trigger mechanism for electrical storm in the "Sabana de Bogota". These conclusions explain the origin and develop of the phenomenum and allow to give some recomendations for its diagnostic and forecasting. Finally an circulation model during the developing of convective activity in the "Sabana de Bogota". [ABSTRACT FROM AUTHOR]

Despite the big institutional efforts, which have taken place in Colombia in order to reduce the seismic vulnerability, today the understanding of the nature of the seismic phenomenon and its space and time distribution is insufficient. The number of stations of the National Seismological Network of Colombia, taking into consideration the country's size, should be larger, and, on the other hand, the sensitivity of the network, determined by the dynamic range and the frequency response of the sensors is not enough in order to determine the characteristics of the microseismicity in Colombia. In order to evaluate the seismic hazard in such an important region like Bogotá, region where the 30% of the population Columbian is located, and concentrates around the 40% of the GNP, is precise identify the spatial distribution of the most important seismic events, as well as the microseismicity, in order to generate a precise model of rupture of the system. In this paper we show the implementation of a regional seismological network, which includes 15, 3-components, broad-broad stations (response: 50 hertz to 120 seconds), with original acquisition and transition systems.
