[en] The study attempts to determine the total population and population growth rates of four (4) age groups per municipality/city within twenty (20), fifty (50) and eighty (80) kilometers from the Philippine Nuclear Power Plant (PNPP-1). The population estimates were done at five (5) year intervals covering the next fifty years. The latest National Census and Statistics Office (NCSO) population projections at the provincial level under the assumption of moderate fertility and moderate mentality decline (series no. 2) were used to derive the estimates of the total population and population growth rates at the minicipality/city levels. The Bureau of Coastal and Geodetic Survey (BCGS) and the NCSO maps served as the bases for delineating the geographic and political boundaries covered by the study. The results will complement the findings of the PAEC project on agricultural parameters for radiation dose calculations and useful for related environmental studies. (author)
[en] A new theory of the population of the Galaxy is considered, based on the hypothesis of the ''blast'' origin of life in the Universe in a certain moment of its development. According to the suggested theory civilizations began to originate around the present moment of the history of the Universe. Their possible number is restricted even when their lifetime is unilimited. The age and the number of the civilizations existing simultaneously, their lifetime being unlimited, are determined by the time scale and time dispersion of evolution of life in different planets from the cell level to a civilization. The suggested theory explains better than the Drake one the negative results of the search of superpowerful extraterrestrial civilizations as well as the non-colonization of the Earth
[en] The new century is characterized by the innovation of new paradigms, it is necessary to fare through unexplored ways of interpreting urban public space not only as a wide open space with greenery, apt for the common use, even for those who are homeless but as a space of physical, economic and social reproduction; a space of recreation, holding memory and collective symbols; a space where social struggle occurs. Such an adventure implies the development and the pairing of a diverse set of concepts, methods and knowledge; emphasizing on the issues that are waiting to be solved rather than on the disciplinary boundaries that may well diminish the solving possibilities at hand. The social nature of urban public space, and the challenges posed by critically reviewing both public policy making and the different practices of agents within the construction process of urban public space, provide researchers with subjects, new issues and reflection spaces waiting to be solved in the post society.
[en] The author's practical experience from demographic data processing is described. The data were used to calculate the collective effective radiation doses using the HAVAR atmospheric dispersion modelling system. The topics of legislative regulation, availability and form of demographic data for the specific purposes in the Czech Republic, methodology of the processing and time development of age distribution of the population are discussed.

[en] The origin and evolution of the term guild are analyzed, as well as its application in ecology, considering the multiple connotations that have been given and the confusion that has been generated by using it improperly. Likewise, the importance of homogenizing the terms and clearly defining the guilds is discussed, to have a language that allows understanding the scope of the term without ambiguities. The use of the term, as well as its persistence in ecological studies, suggests that it has considerable relevance depending on the form and the way it is used. The inappropriate or derivative use of this term is risky and dangerous since it tends to reduce the term to an empty word with multiple meanings. Also, this trivialization constitutes a threat to the proper use of the guild concept in ecology and its meaning as a whole.
[en] The study presents a brief synthesis of the tragedy occurred on September 27Th 1987 in Villatina and the subsequent interventions? Afterwards, compares the interpretations of the event at 3 different times (1987, 1993 and 2007), from the perspective of the settlers remained in the district and of those relocated by several programs, and its incidence on the conception of risk? it also analyzes the transit from informality to formality, emphasizing the challenge of in the commitments acquired by the population, in the relationships with neighbors from the new surroundings and in the organizational processes
[en] Since the twentieth century, local governments in different cities of Latin America started implementing neoliberal urban policies with the aim of configuring economically productive cities. Cities seek to improve their location factor by attracting visitors and investors. This led to a change, from the logic urban government administration to the entrepreneurial city. One of the most significant consequences of this urban policy is that public spaces become more selective. They are turned into new centralities, oriented at sectors of high-income, locally and internationally, which leads to the deepening of socio-economic polarization, giving rise to fragmented and unequal cities. The production of a certain space takes places by the urban policies as well as by the local actors. Public space is one of the places where the tension between these two scales is carried out. This tension arises from the conflict about which actors are responsible for the implementation of new parameters of who uses and consumes the public space and how. This article addresses the configuration of public spaces in two case studies in Latin America: The construction of the Boulevard Naciones Unidas in Quito, and the urban intervention in the neighborhood of La Boca in Buenos Aires.
[en] The analysis puts the focus on a large-scale project by referring to questions about public space policies and considering aspects of globalization in this context. The present text focuses on the growing significance of public space for sustainable urban development and investigates the changing image of public space in general and existing planning instruments ensuring its prospective quality. It discusses the influence of globalization by using the concept of iconic city and the role of public space in this regard. Although closely linked to one another, their interaction - e.g. in terms of potentials, problems and quality aspects - has hardly been investigated yet. Changes in the policies of public space in Vienna underline the importance of this approach. The example of the Aspern Urban Lakeside even shows a tendency of change from iconic architecture towards iconic public space.
[en] This paper is about evolution of vulnerability to hazards related to landslides and floods in Northeast of Medellin between 1960 y 1990, connecting urban planning and politics for informal settlements with land occupation processes which have influenced forming of urban vulnerable communities. Case study analysis shows that vulnerability conditions moved following land occupation trajectories and city expansion according to intrinsic adaptation characteristics of settlement inhabitants to environmental conditions, regional processes and dynamics influenced by city politics. Due to accumulation of vulnerability it is interpreted as an environmental impact of processes that influence its configuration which is not static spatial or temporarily neither it correspond to a cause-effect approach but it is complex and connected to other urban environmental expressions
[en] This article the places of urban life are analyzed through the concept of relational public space, reconsidering public space not just as a theme, but a field of generating abstract scientific knowledge from everyday life. It seeks to expand our scientific perspective from single perspectives to co-research, the latter understood as learning process between cultures and disciplines. Transferring this to another level, means leaving the statics of monolithic disciplinary arguments and heading towards the dialectical investigation of relations between (two or more) perspectives, in this way linking back the theoretical dialogue and the interpreted public space which have been generated in the course of the project. We will reflect on the potentials of relational public spaces to stimulate learning processes in academia itself via participatory action research. After having established a link directed at co-research between Europe and Latin America, we are interested in the epistemological potentials that public spaces might bear for scientific learning experiences between cultures and disciplines, simulating heterogeneous social spaces and spatial practices in the lived public spaces of universities. That way our objectives to propose an action and reflection approach to actively change the mental production of public space.
