[en] This paper develops a proposal for interdisciplinary dialogue through the use of GIS (Geographic Information System) tools for the construction of a methodology to identify the ecological restoration potential ERP in urban edge areas that are part of the Main Ecological Structure of Bogota, according to land management plans. These areas subscribe their own socio-environmental problems particular to their own sign of the interaction between nature and culture. Methodological steps for identification of PER are described: biotic, physical and social characterization, identification and spatialization of variables and weighted overlay for the calculation of the final potential. Then, carry out the discussion on the scope and limitations of using GIS tools and methodological possibility for interaction between disciplines such as biology, physical geography and sociology during the process of ecological restoration.
[en] "A geographic information system (GIS) is a system that captures, stores, analyses, manages and presents data with reference to geographic location data. In the simplest terms, GIS is the merging of cartography, statistical analysis and database technology" [Wikipedia].While many areas of environmental management already depend on GIS, its adoption by the environmental radiation fraternity has been slow and fragmented. This could be due to a lack of understanding of the benefits of GIS or the high cost of operating such systems. However, the value of GIS is starting to be recognised as people become more familiar with GIS technologies through everyday products available now in business or in the home. In Western Australia, some mineral sands companies have built comprehensive GIS databases over the past few years to comply with their environmental licensing conditions. With several new uranium mining developments in WA, they too are looking to GIS to assist with base-line studies and preparation of their Environmental Review and Management Programs (ERMP). Meanwhile, the International Commission for Radiological Protection (ICRP) has signalled changes to the current radiation protection policy for dealing with radiation exposures to non-human organisms. Any change in this policy is likely to increase the workload of professionals involved with environmental radiation monitoring. On another front, the recent Fukushima nuclear disaster in Japan has heightened the public's and media's negative perceptions of environmental radiation and nuclear power. The public and therefore the government increasingly expect the mining industry to demonstrate that radiation from their activities does not cause detriment to people or the environment. Environmental radiation monitoring at a mine can extend over decades from original base-line studies right through mining to rehabilitation and final closure. Monitoring is expensive, labour intensive and provides vast amounts of data to manage, analyse and visualise. The Mining Industry could ease this administrative burden by using GIS. This paper discusses the types of information that can be stored, how it can be analysed, the types of software tools available and the outputs that can be generated from such systems.
[en] This historical account covers the creation of the French nuclear documentation network, the preliminary research, aims, structures and first accomplishments of the Association Francaise de Documentation et d'Information Nucleaire (AFDIN) (French Association of Nuclear Documentation and Information) and its relations with the international system INIS

[en] Critical experiment facilities produced a large amount of important data during the past forty-five years. However, much useful data remains unpublished. The unpublished material exists in the form of experimenters' logbooks, notes, photographs, material descriptions, etc. This data could be important for computer code validation, understanding the physics of criticality, facility design, or for setting process limits. In the past, criticality specialists have been able to obtain unpublished details by direct contact with the experimenters. Obviously, this will not be possible indefinitely. Most of the US critical experiment facilities are now closed and the experimenters are moving to other jobs, retiring, or otherwise becoming unavailable for this informal assistance. Also, the records are in danger of being discarded or lost during facility closures, cleanup activities, or in storage. A project was begun in 1989 to ensure that important unpublished data from critical experiment facilities in the United States are archived and made available as a resource of the US Department of Energy's Nuclear Criticality Information System. The objective of this paper is to summarize the project accomplishments to date and bring these activities to the attention of those who might be aware of the location of source information needed for archiving, and could assist us in getting the materials included in the archive
[en] The experience of Czechoslovakia in the development of data bases in the field of nuclear science and engineering is briefly outlined. It is suggested, that information on an object should be subdivided into invariable in the process of data base operation and regularly supplemented, depending on formalization degree - into information with invariable and variable field length; depending on the type of the source - into primary and secondary information
[en] Gas and electric power transmission utilities operate widely geographically dispersed infrastructure. Due to this fact for the effective operations they have to use location information. Geographic Information Systems are designated for registration of location information about transmission network associated with the technical and operation data and are used for documentation, planning, designing and maintenance purposes. Data are entered, updated and distributed by many users working in computer networks on the shared computer model of transmission network. (author)
[en] This research evaluates and analyzes the spatial distribution communities of periphyton and aquatic macroinvertebrates used in determining water quality, considering the work done previously by de GAIA group at the University of Antioquia on water stream Ayura. We used the functions of hydrological models preset into GIS tool, which was conducted the layout of the stream netting with. Through the overlay of thematic layers, was obtained a mapping tool that allowed us to determine the relationship between land uses given to near areas where the sampling stations were located and the population of collected organisms, they were identified at each point. The results allow us to say that, both communities of protists and aquatic macroinvertebrates as indexes established, BMWP Colombia, Dinius and INSG, show a good quality of water resources for the station 1, which are coniferous forest, high and low stubbles; in station 2, it has an acceptable quality, and it has been noticed some buildings there, pastures and monocultures; finally at station 3, located in urban areas, the water quality is lower than previous stations
