<p>The aim of this study is to achieve a greater insight regarding quiet areas in agglomerations and contribute to their identification. The small urban setting of Mytilene located in the island of Lesvos (North Aegean, Greece), was the case study of this research. The need to control and manage environmental noise has led to the implementation of legislation that in many cases overlooks the acoustic perception of individuals. Due to the fact that noise management efforts along with the promotion of quietness in agglomerations, concerns primarily the residents of the city under consideration, it was essential to practically involve them in the decision making process.&nbsp; Based on citizen science contribution, a number of “places” were highlighted. The “places” mentioned from this procedure were checked by means of acoustic measurements, concerning the noise levels that occurred within the 24h period. A novel method regarding the duration, repetition, check spot and the positioning of measurement was used, in order to calculate the day, evening and night period’s noise levels (L<sub>den</sub>). A performance matrix was then created in order to compare the results, in relation to acoustical, functional and visual criteria. Furthermore, in order to evaluate all the potential Quiet Areas in pairwise comparisons, an Analytical Hierarchy Process (AHP) was implemented. The provision of quietness, as a direct ecosystem service, is a major indicator of environmental quality. Additionally, the way that city inhabitants perceive their acoustic surroundings could determine the character of the landscape along with the quality of the soundscape and define the meaning of quietness that still remains vague. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p>

The aim of this study is to achieve a greater insight regarding quiet areas in agglomerations and contribute to their identification. The small urban setting of Mytilene located in the island of Lesvos (North Aegean, Greece), was the case study of this research. Based on citizen contribution, a number of “places” derived that are perceived as “quieter” than others, by the permanent residents of Mytilene. The “places” mentioned from this procedure were checked by means of acoustic measurements, concerning the noise levels that occurred within the 24h period. A novel method regarding the duration, repetition, check spot and the positioning of measurement was used, in order to calculate the day, evening and night period’s noise levels (Lden). A performance matrix was then created in order to compare the results, in relation to acoustical, functional and visual criteria. Furthermore, by incorporating perceptual criteria we assisted the quiet area selection procedure. The provision of quietness, as a direct ecosystem service, is a major indicator of environmental quality. Nevertheless, the way that city inhabitants perceive their acoustic surroundings could determine the character of the landscape along with the quality of the soundscape and define the meaning of quietness that still remains vague.

Urban growth retains a bipolar dissension regarding quality of life as it is both deleterious and beneficial for urban dwellers. Environmental noise could be considered a byproduct of growth, and according to numerus studies, it should not be ignored. The small urban setting of Mytilene located in the island of Lesvos (North Aegean, Greece) was the case study of this research. By implementing a novel protocol, the potential Quiet Areas of Mytilene were highlighted. The methodology consisted of noise measurements, soundscape recordings, and strategic noise mapping using the CadnaA noise prediction software. Furthermore, several soundwalks were conducted with the scope to obtain the citizen perspective regarding Quiet Area management. The way that city inhabitants perceive their acoustic surroundings could determine the character of the landscape along with the quality of the soundscape and define the meaning of quietness, which still remains vague.

Due to irregular and uncontrolled expansion of cities in developing countries, currently operational landfill sites cannot be used in the long-term, as people will be living in proximity to these sites and be exposed to unhygienic circumstances. Hence, this study aims at proposing an integrated approach for determining suitable locations for landfills while considering their physical expansion. The proposed approach utilizes the fuzzy analytical hierarchy process (FAHP) to weigh the sets of identified landfill location criteria. Furthermore, the weighted linear combination (WLC) approach was applied for the elicitation of the proper primary locations. Finally, the support vector machine (SVM) and cellular automation-based Markov chain method were used to predict urban growth. To demonstrate the applicability of the developed approach, it was applied to a case study, namely the city of Mashhad in Iran, where suitable sites for landfills were identified considering the urban growth in different geographical directions for this city by 2048. The proposed approach could be of use for policymakers, urban planners, and other decision-makers to minimize uncertainty arising from long-term resource allocation.

The pandemic of coronavirus disease (COVID-19) led to the need for drastic control measures around the world to reduce the impact on the health of the population. The confinement of people in their homes resulted in a significant reduction in human activity at every level (economic, social, industrial, etc.), which was reflected in a decrease in environmental pollution levels. Studying the evolution of parameters, such as the level of environmental noise caused by vehicle traffic in urban environments, makes it possible to assess the impact of this type of measure. This paper presents a case study of the acoustic situation in Cáceres (Spain) during the restriction period by means of long-term acoustic measurements at various points of the city.

Using heritage as a cultural artifact in city development is not new, but little has been explored about how urban heritage can be utilized as new generative value and a new planning instrument for the revival of cities. The purpose of this paper is to show the creative and the generative use of urban heritage, both for the extension of cultural and tourist offer of the city and for the improvement of the quality of life in physical, social and economic terms for the community. The case study method was used for the adaptive reuse of projects for heritage buildings and urban revival in Kikinda. We argue that urban heritage has to be used, bearing in mind its spatial, economic and social sustainability aspects, and become a generator of urban revival. We go beyond recognition of the value of heritage as a cultural artifact that should solely be preserved and used as a static element in urban development, and view it more as a dynamic asset for city revival processes. We found that for the heritage nodes to be utilized as the new generative value for the revival of cities, they have to be perceived from the network perspective, thus influencing the urban environment in a sustainable way.

ABSTRACT Favelas are low-income urban communities in Brazil, and Maré in Rio de Janeiro has the largest cluster of favelas in the country. The prevailing view of a unique, regulated, and normative city conflicts with the reality of the continued expansion of the favelas, posing challenges for architects and urban planners in developing new strategies for integrating informal areas with the main city. This study focused on a decaying industrial area adjacent to the Maré favelas and explored a sustainable path for improving both the quality of the built environment and the quality of life of the residents. Effective infrastructure and socioeconomic links between the favelas and the city were proposed. The home production model that emerged from the favelas inspired the use of the abandoned industrial area as a home-industry incubator. The study proposed an urban regeneration strategy involving a bottom-up industry-space process evolving from home industries to group industries, and finally to larger community industries. This strategy can accelerate Maré’s development and integration with the city of Rio de Janeiro.

The aim of this study was to analyze the level of satisfaction in three municipal sports centers in the city of Malaga and to learn and analyze the characteristics of users older than 40 years of age in these centers. A total of 303 persons (123 men and 180 women) from three sports centers in the city of Malaga participated in this study (M = 58.14, SD = 7.16 years). The Evaluation of Perceived Quality in Sports Services test (CECASDEP) was used, and the results demonstrated that the different dimensions studied—sports center, activity space, locker rooms, program of activities, and trainer—were very positively correlated. The level of customer loyalty increased with user satisfaction and perceived quality of services as well as the age of the person. Users were also found to be more motivated to take part in physical activities due to greater satisfaction. The highest scores were given to the trainers, who played a key role in all three sports centers. In conclusion, we gathered important insights into perceived quality in different sports centers. This information can be used by sports managers to strengthen dimensions with lower scores and improve those with higher scores. In addition, the study confirms that the level of customer loyalty is related to the perceived quality scores. Therefore, the use of measuring instruments is recommended to optimize the quality of sports services.
