Experiencias desde la Gestión Ambiental Urbana
Usually the built heritage; the constructed floor; cultural diversity, and cultural landscapes are managed as objects of urban system and identifying value to society, and not as environmental problems , mainly urban . For urban environmental management behaves built heritage as environmental resources; Since they are the result of the interrelation – society-nature . Although treated even in a limited way, so it is not commonly done management from this perspective. One reason for this is the sectorial approach, which associates the resource with its origin. A conceptual model and a methodology are development to integrate concepts, instruments and tools, which will provide a change in the state of urban environment through conservation of resources, built heritage value. The experiences of urban environmental management developed under ecosystem, strategic and participative approaches has allowed people of Holguin province , deploy conservation experiences . His main contribution has been to integrate the isolated efforts of the entities that manage these resources under the criteria of their contribution to local development from an environmental perspective that allows a group to meet social needs associated with specific conservation and urban areas; the environmental status of the city.

IL LEGNO LAMELLARE
The static conception of a warp of ''curved beams'' according to a horizontal position plane, hypothesized in glulam, it has had to confront with the impossibility of achieving structural elements with the desired geometry; the productive scenery, at present, solves only solutions arc mixtilinear, the only type derivable from the glulam with horizontal arrangement of the slats. This study, including the reasons for the detected limit, has investigated the technological feasibility of the glulam with a vertical arrangement of the slats, the only one that would allow a curvature in the horizontal position plane. To proceed in this direction, it was considered essential, advance, characterize the new material under the theoretical-experimental profile, analyzing the technical problems, to be addressed through a review of the production cycle, and researching the failure mechanisms, through a program of experimental tests.
The seismic vulnerability of vernacular architecture
The urban census, here proposed, is aimed at an expeditious as articulated knowledge of state of consistency, conservation and seismic risk of the architectural vernacular heritage, especially from the point of view of the seismic vulnerability, giving as assumed the condition of unpredictability of an seismic event, which is as evident as the probability of an earthquakes, characterized by an assigned intensity, in a pre-defined areas and considering a pre-assigned time window. The tool, described below, does not have a technical value in the narrow sense, it primarily do not want to suggest how to act on historic vernacular buildings, but rather it wants to provide general technical data of whether it is possible to intervene, proposing a preliminary scenario about outcomes, which are reasonably obtainable in particularly complex and compromise, contexts as, at first glance, it might seem, in terms of preservation of historical architectural vernacular heritage, in the case study of San Procopio. The contextual conditions are often the reason of the need to propose an expeditious tool, which is not only fast and unique, although at the same time able to document and represent complexity and variants of an architecture without architects, but also able to be used with a good level of control and uniformity by the average practitioner and professional, although not particularly experienced under the point of view of how to read and understand the ancient building, above all if not monumental, especially in terms of seismic performance.
LA HABANA VIEJA Y EL ENFOQUE SUSTENTABLE
In this communication are established some concepts and basic principles of the sustainable approach at an international scale. The criterions of the author are provided in this sense beginning from the specific examples of the Cuban scenario. In particular, it´s exposed the case of the Historical Center of the Old Havana and its development since the 80's, beginning from the establishment of its Master Plan as an organized guide of the work and integral management of the habitat.
The Historical Center of Havana was declared since 1982 as a Humankind Heritage. Since then the City Historian's Office and in particular its maximum leader the Dr. Eusebio Leal Spengler, have been developed a huge labor to achieve an improvement of that locality, taking into account a sustainable approach.
Some of the actions and results obtained in the Historical Center of Havana are presented as a singular case in Cuba, its successes and mistakes; but mostly, are examined the main objectives pursued in order to increase the life quality of the population living in the Historical Center and the vision of future that has the Office to find the solution for the most pressing problems of the place, as a approximation way to the achievement of sustainability in the cities and in particular in a high valuable location.
Keywords: sustainability, participative management, conservation, transformation.
KARL H. BRUNNER E L'URBANISTICA ORGANICA IN COLOMBIA
Between 1900 and 1950, the Latin American cities have received cultural influences from Europe. The main cities of South America, in those years, were suffering from severe alterations and environmental changes, and the social contrasts were many strong. The Latin American city had lost its cultural identity and, at the same time, the city was trying to acquire a new image. In this complex cultural context advances the Austrian city planner Karl Brunner (1887-1960). Brunner had studied in Vienna and in 1929 he had started working in Chile and then in 1933 in Colombia. Brunner works 20 years of his life in Latin America where he left important works and contributions. This paper intends to analyze the work of Karl H. Brunner for the development plan of Bogotá's city (1933-1938) and the introduction of organic planning.
