The earthquake that hit the city of L’Aquila, in central Italy, on the 6th of April 2009 has severely damaged most of the heritage buildings of the area. Soon after the event, a first survey of damage to ancient churches and palaces has been carried out according to a predefined classification procedure. Subsequently, a more detailed damage analysis was started in order to facilitate decision on future interventions. For one of these churches, S. Biagio Amiterno, damage consisted in the collapse of the upper part of the façade, in the localized collapse of the main vault, and in an extended crack pattern in vaults, columns, and walls. This damage pattern is interpreted here as case study. In more general terms, the exam of specific case studies gives the possibility of shedding light on various issues related to the seismic behavior of the building typologies concerned.

Being the necessary data of the city-scale seismic damage simulations, structural types of buildings of a city need to be collected. To this end, a prediction method of structural types of buildings based on machine learning (ML) is proposed herein. Specifically, using the training data of 230,683 buildings in Tangshan city, China, a supervised ML solution based on a decision forest model was designed for the prediction. The scale sensitivity and regional applicability of the designed solution are discussed, respectively, and the results show that the supervised ML solution can maintain high accuracy for different scales; however, it is only suitable for cities similar to the sample city. For wide applicability for various cities, a semi-supervised ML solution was designed based on sampling investigation and self-training procedures. The downtowns of Daxing and Tongzhou districts in Beijing were selected as a case study for the designed semi-supervised ML solution. The overall prediction accuracies of structural types for Daxing and Tongzhou downtowns can reach 94.8% and 99.5%, respectively, which are acceptable for seismic damage simulations. Based on the predicted results, the distributions of seismic damage in Daxing and Tongzhou downtown were output. This study provides a smart and efficient method for obtaining structural types for a city-scale seismic damage simulation.

The fire incident in karaoke buildings in Indonesia which claimed many lives has occurred several times. According to the National Academy of Science US, the smoke toxins that come out of the fire disaster cause 50-80% of deaths. Refers to the data, it is necessary to check further about the building material response to fire during a fire incident. Masterpiece Signature Karaoke is a karaoke building that classified as large and magnificent in the city of Medan which has various material so that it is necessary to study the interior material as passive fire protection. The purpose is to find out how to assess the reliability of fire passive protection regard to the interior materials and recommendations or descriptions of right interior material planning using the Analytical Hierarchy Process (AHP). This method is efficacious to solve the problem of reliability in using interior materials as passive fire protection in Masterpiece Signature Family KTV Medan building with the results of an Adequate Level of reliability. Then, design recommendations were given for the use of interior materials in karaoke building to improve the reliability results to be better.The results are useful as information for other researchers and karaoke buildings regarding passive fire protection systems at the Masterpiece Signature Family KTV Medan.

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

Abstract Amendment to the Act on special rules of preparation and implementation of investment in public roads resulted in an accelerated mode of acquisition of land for the development of roads. The decision to authorize the execution of road investment issued on its basis has several effects, i.e. determines the location of a road, approves surveying division, approves construction design and also results in acquisition of a real property by virtue of law by the State Treasury or local government unit, among others. The conducted study revealed that over 3 years, in this mode, the city of Krakow has acquired 31 hectares of land intended for the implementation of road investments. Compensation is determined in separate proceedings based on an appraisal study estimating property value, often at a distant time after the loss of land by the owner. One reason for the lengthy compensation proceedings is challenging the proposed amount of compensation, unregulated legal status of the property as well as imprecise legislation. It is important to properly develop geodetic and legal documentation which accompanies the application for issuance of the decision and is also used in compensation proceedings.

Based on the experiences of a Koreatown scholar, the executive director of a Koreatown nonprofit, and a longtime resident student, the article advocates for greater attention to the complex and dynamic power structures of ethnic enclaves in community-academic partnerships. We discuss the changing landscapes of Koreatown as the global nexus of the Pacific Rim economy, the city of Los Angeles’s urban redevelopment plans, and growing diversity and inequality. Programs that aim to engage effectively with ethnic communities must reassess how knowledge is produced and conveyed, how we structure partnerships within stratified communities, and how to grow from issue-based partnerships to broader communities of interest.

The Postponement

Research Question: This analysis arises from the decision of the current local council of Barcelona regarding the postponement of the sporting mega-event ‘World Roller Games’, due to a lack of a social and sportive implication in this event. This research tries to shed some light on the matter and give evidence to the local council to become the world capital of skating. The research question is to analyse whether non-economic impacts could be relevant enough to organise a mega-event.Research Methods: The methodology is based on the perception and experience of spectators and participants on four main impacts (social, economic, sports city image and sports practice) using a survey from a National Roller Skating Championship in Spain, considering that this profile of respondents have a better knowledge of the current situation of this sport.Results and Findings: There are positive expected future consequences of this mega-event to be held in Barcelona in social and sportive terms. We can also conclude that the local council must still introduce some social and sportive policies in the city in order to improve the chances of success in social, sports practice and sportive brand image development.Implications: It is demonstrated that a mega-event should not be seen purely from a perspective of business generation, especially with minority sports like roller skating. There is a clear opportunity to develop social and sportive practice initiatives that can push social cohesion throughout the city thanks to a mega-event such as this one.
