A survey was conducted in Lefkada Island in Greece, where 200 interviewees took part in order to consider whether they wish to voluntarily participate in the excavation and restoration of the ancient theater of Lefkada. Half of the interviewees were given information on the history of the site and then were asked to fill out a questionnaire. The other half of the interviewees were given no historical information on the archeological site and also were asked to fill out a questionnaire. The interviewees who were not given any information on the history of the site briefed on the history and then were asked to fill out another questionnaire. The purpose was to observe the different responses that the interviewees gave before and after being informed. This study aims to compare the WTP （Willingness To Participate） for this public good among those who were informed and those who were not.展开更多

However, it is observed that the practice of periodic inspections is not yet part of the culture of a certain segment of the population that does not have economic means and knowledge of the importance of maintenance to ensure the integrity of the structure. It was used in this work an inspection script with use of tests and methodology to quantify damage and to check the state of degradation of two residential buildings with more than 20 years and built near the seafront where environmental aggression is strong. The deterioration found in each of the buildings has been differentiated due to different corrective maintenance performed at every building. The last maintenance, performed in Building A, was performed by corrective hand of unskilled labour guided by the community itself, which has no expertise in the field of civil engineering. In Building B, the situation is similar, compounded by the opinion of some tenants that there is no need for this routine, even the structure being in critical condition, as was confirmed with the application of the methodology employ. There should be a legislation that governs the execution of inspections and maintenance programs in addition to the existing technical standards. The methodologies presented suitable for checking the degree of degradation of the structures and performed tests confirmed the diagnosis obtained by visual inspection and quantification of damage.展开更多
