On October 30, 2020, an earthquake about 70 km away from the city center of Izmir with a 4.3 million population has shaken the city tremendously and has resulted in destruction of many building type of structures due to an unexpected high soil-amplified vibrations very similar to the Mexico City earthquake in 1985. The bridges at the soil-amplified sites has performed in elastic range with no damage at all. In the city of Izmir, the 42 year old twin bridges located on the main transportation route, were tremendously shaken by the earthquake had observed to have no seismic induced damage. Surprisingly twin bridges suffering from the alkali silica reaction (ASR) over the years did not even pound to each other despite the small size of longitudinal gap between them. As it has been known, the past performance of Turkish designed bridges are typically succesfull with almost no damage as observed in the Van 2011 and Sivrice 2020 earthquake mainly due to allowing movements at their joints and to flexible type of framing. The focus of the paper is given to understand the successful performance of bridges and to investigate the non-pounded twin bridges of the Izmir city. In this scope, a bridge inspection has been performed and the twin bridges have been analyzed for the recorded ground motion. The results have indicated that the structures have been subjected to 0.3 g at their vibration modes and the twin bridges have a synchronized motion due to having the identical vibration mode shape with a period of 1.5 seconds

The present work explores the recognition of the past and present genius loci of three spaces of Porto city center as remaining and transformed representations of spaces with distinct, interconnected and pertinent botanical missions in the nineteenth century landscape of the city. Through the exploration of sources left by the interveners or graphic testimonies of the urban landscape from 1850 to the present day of these (ethno-)botanical spaces, we explore how the interveners and spaces of the Jardim Botânico da Academia Polythecnica do Porto, the Horto-pharmacêutico da Botica da Hospital Real de Santo António and the Horto das Virtudes mutually influenced. On the other hand, it is demonstrated how these spaces determined a time of special interest in botany that would not be repeated in the history of the city and its population.

The gradual modernization of commercial activities during the past 20 years has had a deep impact on the urban landscape of Ancona and has strongly affected the stable relationship that for decades had marked the city center and its suburbs. The traditional hierarchy of commercial areas has undergone a new configuration due to suburban territorialization processes brought by a large-scale polarization of the city’s suburbs. Understanding these new commercial hierarchies represents a valid tool for planning proper territorial policies and boosting more resilient-based processes which aim at restoring the primary role of a city center that has slowly lost its social appeal and its functional status-quo within the city’s metropolitan area and in the urban network of the Marche.

AbstractSeveral kampong in the Surabaya city are currently used as tourist destinations, by offering the uniqueness of the kampong. One of the kampong that has succeeded in becoming a tourist destination is Kampung Maspati, which is located in the city center. The ancientness of the kampong is offered to tourists so they are interested in visiting it. One of the weaknesses, Kampung Maspati does not have a historical narrative that explains the development of the kampong from the past until now. The Department of History, Faculty of Humanties, Universitas Airlangga organizes community service activities to assist in writing village history, o increase the promotion of kampong tourism.

The findings obtained from these activities are that the understanding of the people of Kampung Maspati on the history of the kampung is still not good, so that continuous assistance is needed. This kind of activities also needs to be extended to others kampong because currently there are still many historic kampong in the Surabaya city that do not yet have historical narratives. This activity needs to be done so that the promotion of kampong tourism can be improved.Keyword: kampong tourism, promotion, Maspati, SurabayaAbstrakBeberapa kampung di kota Surabaya saat ini dijadikan sebagai tujuan wisata, dengan menawarkan keunikan yang ada di kampung tersebut.

Based on the previous research on the former of Semarang capital city, Kanjengan, there is a supposition that the area is a coastal city. As the consequence of the sedimentation process occurred by Java Island, Semarang city, and some cities in Java are no longer on the seashore. The cities that are archived in the Map of Indonesia in the 15th century and some records from foreign sailors, absolutely have several different conditions compared to the past and the present condition.  How the architecture and the city’s patterns of the Old Semarang? The method of this research was conducted by exploring historical articles, toponyms, maps, and old pictures which were then compared with the remaining architecture and spatial patterns. The reading of old maps and pictures was done by using the seeing by believing approach. The analysis was performed by using the manual sketch. The architectural heritage like the former lighthouse, commercial corridors in the north of the square, and toponyms were tools to prove that the area was a seaport and a waterfront city. Old Coastal Semarang has an Architecture and urban design concept as the main gate from the sea to the city center at the time. Surrounding the main gate, they were the existence of the former lighthouse (the Menara Layur Mosque), multi-ethnics houses, toponyms indicating that some places were a former harbor, and the remaining trade corridor connecting the port and the local government center. This concept is similar to the Islamic Sultanates on the north coast of Java and the waterfront-based cities in the interior of Java. It is assumed that Semarang Old city has a similar role with the other Islamic Sultanates. This area is proper to be a city conservation area and become a part that is integrated into future urban planning.

Place branding is a network of associations in the consumer’s mind, based on the visual, verbal, and behavioral expression of a place. Food can be an important tool to summarize it as it is part of the culture of a city and its symbolic capital. Food is imaginary, a ritual and a social construction. This paper aims to explore a ritual that has turned into one of the brands of Lisbon in the past few years. The fresh sardines barbecued out of doors, during Saint Anthony’s festival, has become a symbol that can be found on t-shirts, magnets and all kinds of souvenirs. Over the year, tourists can buy sardine shaped objects in very cheap stores to luxurious shops. There is even a whole boutique dedicated to the fish: “The Fantastic World of Portuguese Sardines” and an annual competition promoted by the city council to choose the five most emblematic designs of sardines. In order to analyze the Sardine phenomenon from a city branding point of view, the objective of this paper is to comprehend what associations are made by foreigners when they are outside of Lisbon. As a methodological procedure five design sardines, were used of last year to questioning to which city they relate them in interviews carried in Madrid, Lyon, Rome and London. Upon completion of the analysis, the results of the city branding strategy adopted by the city council to promote the sardines as the official symbol of Lisbon is seen as a Folkmarketing action. The effects are positive, but still quite local. On the other hand, significant participation of the Lisbon´s dwellers in the Sardine Contest was observed, which seems to be a good way to promote the city identity and pride in their best ambassador: the citizens.

City centers worldwide are perceived as essential parts of the city, where city memories are preserved and its identity is expressed. They are planned to satisfy the functional requirements and pleasurable qualities of the city. Under the accelerating urbanization of the modern city, several challenges face these centers including demographic, economic, and environmental challenges. This requires a continuous and incremental urban development process based on clear strategy and action plans. Thus, this study focuses on urban development strategies of city centers, with a focus on Rafah city located in the Gaza Strip, Palestinian Territories. The geographic location of this city near the Palestinian-Egyptian borders makes it a promising commercial city at local and regional levels. Thus, the current situation of Rafah city center has been analyzed, and several development strategies have been proposed. This has been done through a field survey based on observation and a questionnaire directed to city center users. It has been found that there is a great potential of Rafah city center to be developed as a commercial center. In this regard, several strategies and required actions have been proposed in the fields of transportation, environmental quality, shopping activities, investment opportunities, and visual perception.
