Historical Centre

In the 1970s, the fragile historical centre of the city of Perugia was a key area where the binomial of sustainable mobility and urban regeneration was developed and applied. At the turn of the xxi century, the low carbon automatic people-mover Minimetrò broadened that application from the city's historical centre to the outskirts, promoting the enhancement of several urban environments. This paper is the outcome of an investigation of original sources, field surveys and direct interviews, which addresses the Minimetrò as the backbone of a wide regeneration process which has had a considerable impact on the economic development of a peripheral area of the city which was previously devoid of any clear urban sense. The conclusion proposes some solutions to improve the nature of the Minimetrò as an experimental alternative means of transport.

Dengue Epidemic

Abstract Background Dengue fever (DF) is a mosquito-borne infectious disease that has threatened tropical and subtropical regions in recent decades. An early and targeted warning of a dengue epidemic is important for vector control. Current studies have primarily determined weather conditions to be the main factor for dengue forecasting, thereby neglecting that environmental suitability for mosquito breeding is also an important factor, especially in fine-grained intra-urban settings. Considering that street-view images are promising for depicting physical environments, this study proposes a framework for facilitating fine-grained intra-urban dengue forecasting by integrating the urban environments measured from street-view images. Methods The dengue epidemic that occurred in 167 townships of Guangzhou City, China, between 2015 and 2019 was taken as a study case. First, feature vectors of street-view images acquired inside each township were extracted by a pre-trained convolutional neural network, and then aggregated as an environmental feature vector of the township. Thus, townships with similar physical settings would exhibit similar environmental features. Second, the environmental feature vector is combined with commonly used features (e.g., temperature, rainfall, and past case count) as inputs to machine-learning models for weekly dengue forecasting. Results The performance of machine-learning forecasting models (i.e., MLP and SVM) integrated with and without environmental features were compared. This indicates that models integrating environmental features can identify high-risk urban units across the city more precisely than those using common features alone. In addition, the top 30% of high-risk townships predicted by our proposed methods can capture approximately 50–60% of dengue cases across the city. Conclusions Incorporating local environments measured from street view images is effective in facilitating fine-grained intra-urban dengue forecasting, which is beneficial for conducting spatially precise dengue prevention and control.

Thanks to their widespread usage, mobile devices have become one of the main sensors of human behaviour and digital traces left behind can be used as a proxy to study urban environments. Exploring the nature of the spatio-temporal patterns of mobile phone activity could thus be a crucial step towards understanding the full spectrum of human activities. Using 10 months of mobile phone records from Greater London resolved in both space and time, we investigate the regularity of human telecommunication activity on urban scales. We evaluate several options for decomposing activity timelines into typical and residual patterns, accounting for the strong periodic and seasonal components. We carry out our analysis on various spatial scales, showing that regularity increases as we look at aggregated activity in larger spatial units with more activity in them. We examine the statistical properties of the residuals and show that it can be explained by noise and specific outliers. Also, we look at sources of deviations from the general trends, which we find to be explainable based on knowledge of the city structure and places of attractions. We show examples how some of the outliers can be related to external factors such as specific social events.

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.

This article discusses how an aspect of urban environments – sound and noise – is experienced by people walking in the city; it particularly focuses on atypical populations such as people diagnosed with psychosis, who are reported to be particularly sensitive to noisy environments. Through an analysis of video-recordings of naturalistic activities in an urban context and of video-elicitations based on these recordings, the study details the way participants orient to sound and noise in naturalistic settings, and how sound and noise are reported and reexperienced during interviews. By bringing together urban context, psychosis and social interaction, this study shows that, thanks to video recordings and conversation analysis, it is possible to analyse in detail the multimodal organization of action (talk, gesture, gaze, walking bodies) and of the sensory experience(s) of aural factors, as well as the way this organization is affected by the ecology of the situation.

Dirofilariosis is an emerging mosquito-borne veterinary and medical problem in the Northern hemisphere. The ecological investigation of 56 canine dirofilariosis cases in new endemic locations was performed in Szeged, Hungary. The aim was to analyse the influence of the spatial patterns of dog abundance and the potential mosquito breeding habitats on the spatial occurrence patterns of dirofilariosis in the city of Szeged. The limnoecological characterisation was based on the fluvial habitat classification of Amoros of natural water bodies; the built environment was evaluated using the UrbanisationScore urbanisation intensity measuring software. Dirofilaria immitis accounted for 51% and D. repens for 34.3% of the dirofilariosis cases, and in 20% of the cases only the Knott’s test was positive. It was concluded that most of the cases were related to locations with a medium to high urbanisation index, although the proximity of mosquito-bearing waters also played an important role in the observed spatial infection patterns. We found that the distance from potential mosquito habitats and the urbanisation intensity determine the abundance of dirofilariosis in urban environments.

AbstrakTanaman sangat penting untuk menunjang kehidupan sebagai penunjang kesehatan, pengendali iklim mikro, menyerap polusi bahkan berguna meningkatkan kualitas visual. Kehadiran tanaman di lingkungan perkotaan semakin sulit, mengingat lahan-lahan perkotaan semakin sempit terutama di lingkungan permukiman kota yang umumnya padat dan menyisakan sedikit ruang untuk tanaman. Berbeda dengan permukiman-permukiman padat pada umumnya, Kampung Cibunut RW 07 khususnya RT 05 Kota Bandung terlihat lebih asri, banyak sekali tanaman di lingkungan ini, meskipun lahan terbuka sedikit, gang juga tidak terlalu besar dan teras-teras rumah sangat terbatas. Melihat perkembangan yang sangat baik di Kampung Cibunut, maka penelitian ini layak untuk dilakukan dengan tujuan untuk mengidentifikasi jumlah dan jenis tanaman, serta cara dan metoda penanaman di ruang sempit dan mengetahui luas diameter tajuk tanaman. Digunakan metoda deskriptif kualitatif, data dikumpulkan melalui survey dan studi pustaka. Data primer diperoleh melalui observasi lapangan, pengukuran dan pencatatan langsung di lapangan. Setiap tanaman diberi nomor, dan dicatat kemudian seluruh data akan dimasukan ke dalam matrik untuk memudahkan perhitungan. Pembahasan dilakukan untuk mendapatkan ragam jenis tanaman, sistem dan cara penanaman, dan luas total tajuk tanaman. Diharapkan hasil dari penelitian ini dapat ditiru dan diterapkan di permukiman padat sejenis di kota Bandung agar dapat meningkatkan keasrian kawasan dan penyerapan polusi.Kata kunci : Tanaman, Unsur Hijau, Lahan sempit, permukiman padat. AbstraCTPlants are very important to support life as health support, control the microclimate, absorb pollution, and even improve visual quality. The presence of plants in urban environments is increasingly difficult, given that urban lands are increasingly narrow, especially in urban residential areas which are generally dense and leave little room for plants. Unlike the dense settlements in general, Kampung Cibunut RW 07, especially RT 05 Kota Bandung, looks more beautiful, there are lots of plants in this environment, although there is little open land, the alleys are not too big and the terraces of the houses are very limited. Seeing the excellent development in Cibunut Village, this research is feasible to do the aim of identifying the number and types of plants, as well as methods and methods of planting in narrow spaces and knowing the diameter of the plant canopy. Qualitative descriptive method is used, data is collected through surveys and literature studies. Primary data obtained through field observations, measurements, and direct notes in the field. Each plant is numbered, recorded and then all data will be entered into a matrix to facilitate calculation. Discussions were conducted to obtain various types of plants, planting systems and methods, and the total area of the plant canopy. It is hoped that the results of this research can be replicated and applied in similar dense settlements in the city of Bandung to increase the beauty of the area and the absorption of pollution. Keywords: Plants, Green Element, Narrow land, dense settlement.

Resumen: El "hameau" vertical de Le Corbusier es un prototipo de alojamiento colectivo, desarrollado como alternativa plástica a la "Unité d'habitation de grandeur conforme", quizás su obra más sintética. La torre residencial se concreta a partir de las teorías urbanas de la regla de las 7V, a través de la impronta de una de las formas elementales: el volumen cilíndrico, manteniendo prácticamente inalteradas capacidad, forma y dimensiones en cualquiera de los entornos urbanos donde se inserta, los proyectos no construidos de su última etapa para Europa. Lejos de ser un modelo genuino es deudor de otras construcciones previas, los albergues para las colonias infantiles italianas, promovidas por la fábrica FIAT en los años 30, y algunos experimentos residenciales del arquitecto francés Auguste Bossu, erigidos también por esos años en la ciudad de Saint-Étienne. El artículo traza las relaciones entre estas construcciones y las aldeas cilíndricas para solteros, analizando las particularidades de su estructura formal y la dinámica de su organización interna, para comprobar cómo son adoptadas por Le Corbusier en la constitución de la identidad de un nuevo tipo de vivienda colectiva que permanece todavía a la sombra de sus proyectos más reconocidos. Abstract: The vertical "hameau" of Le Corbusier is a prototype of collective housing, developed as a plastic alternative to “Unité d’habitation de grandeur conforme", perhaps his most synthetic work. The residential tower is generated from urban doctrine of 7V theory through the shape of one of the elementary forms: the cylindrical volume. The towers keep capacity, shape and dimensions unchanged in any urban environments where they are inserted: the unbuilt urban projects in his last stage in Europe. Far from being a genuine type, is based in other previous constructions; the children's summer camps sponsored by the Fiat factory in the 30s, and some residential experiments by French architect Auguste Bossu erected by those years in the city of Saint-Etienne. The article describes the relationship between these structures and the cylindrical villages for singles and analyzes the peculiarities of their formal structure and the dynamic of their internal organization in order to check how those constructions were adapted by Le Corbusier for the constitution of a new collective type dwelling which still remains in the shadow of his most famous projects.  Palabras clave: Le Corbusier; hameaux verticaux; comuna cilíndrica; torre residencial.
