ABSTRACT
In the post-pandemic era, cities are facing new demands and challenges. Both telecommuting and dense development require communities to provide more public space to meet people's psychological and physical needs. The insufficient space currently left in the city calls for stock development. The Japanese public libraries affected by COVID-19 are part of this stock. We aimed to determine and propose strategies for using the external space of libraries to enhance the sustainability of cities. Ultimately, we expect to achieve a synergy between public libraries and cities in terms of sustainability. We found that the most dominant element in the exterior space of Japanese public libraries is parking lots, which have the potential to be flexibly utilized in the post-pandemic era. We also summarized the current patterns of external space for public libraries in Japan. Finally, we proposed six strategies to enhance the sustainability of libraries and cities. These strategies can simultaneously enhance the sustainability of cities and public libraries from multiple perspectives, especially in the post-pandemic era. Our proposal will not only help to build or renew public libraries in the future, but also fills a gap in the urban perspective of Japanese public libraries and their external spaces.
ABSTRACT
Playability is an attribute that refers to the ability to stimulate individual responses or collective action in an immersive activity in an exploratory way. Playability is an important component of the enjoyment and well-being of urban dwellers, has the potential to stimulate urban vitality and is an important expression of the inclusiveness and equity of urban space. The pursuit of economic development and efficiency-oriented urban construction has led to the domination of urban space by overcrowded traffic, economy-oriented commerce and densely populated housing. Moreover, the existence of playable space has become a scarce resource and is seen as a site for the materialisation of social rights. As the haze of the COVID-19 pandemic fades and cities are again exposed to wider and more participatory use, determining how to adapt urban spaces to the playability needs of users of different ages, cultural backgrounds and social classes, and provide them with appropriate site use and experience, is becoming a hot issue of concern for building equitable and high-quality urban spaces. The study of the playability of urban spaces is highly complex, and the related research on social justice is cryptic. In order to better investigate the social equity aspects of urban playability, this paper integrates scientometric and manual methods to review the relevant research. This paper takes 2664 related papers from the Web of Science (WOS) core dataset from 1998 to 2022 as the research object and employs CiteSpace to organise the existing research results of playful urban spaces. Quantitative analysis is used to clarify the theoretical foundations, developments and research hotspots of urban spatial playability, while the manual collation and generalisation of the studies uncover the hidden issues of social justice research. Based on the proposed research method, we summarize the key three research stages related to urban spatial playability and social equity. We also discuss the development of urban spatial playability in the perspective of social justice from three aspects: micro, meso and macro. The results can help readers better understand the current status and development process of research on playful urban space. In particular, we clarify the issues related to social justice under the theme of the playability of urban spaces and provide directions for future research on building playful cities and promoting the development of urban socio-spatial equity.
ABSTRACT
We employed publicly available user-generated content (UGC) data from the website Tripadvisor and developed an autoregressive integrated moving average (ARIMA) model using the R language to analyze the seasonality of the use of urban green space (UGS) in Okinawa under normal conditions and during the COVID-19 pandemic. The seasonality of the use of ocean-area UGS is primarily influenced by climatic factors, with the peak season occurring from April to October and the off-peak season from November to March. Conversely, the seasonality of the use of non-ocean-area UGS remains fairly stable throughout the year, with a relatively high number of visitors in January and May. The outbreak of the COVID-19 pandemic greatly impacted visitor enthusiasm for travel, resulting in significantly fewer actual postings compared with predictions. During the outbreak, use of ocean-area UGS was severely restricted, resulting in even fewer postings and a negative correlation with the number of new cases. In contrast, for non-ocean-area UGS, a positive correlation was observed between the change in postings and the number of new cases. We offer several suggestions to develop UGS management in Okinawa, considering the opportunity for a period of recovery for the tourism industry.
ABSTRACT
This book explores the multifaceted obstacles to social change that India, Myanmar and Thailand face, and ways to overcome them. With a collection of essays that identify common challenges and salient features affecting diverse communities, this volume examines topics from subnational and local perspectives across the peripheries. The book argues that identity-based divisions have created a system of oppression and political contention that have led to conflicts of different kinds, and hence serving as the common cause of different social issues. At the same time, such issues have created space for marginalized groups around the world to call for change. The volume recognizes that social transformation comes into being through an active process of deconstructing and reconstructing shared norms and ideas. The contents in this book are thus centered around two focuses: The impacts of identities and grassroots. Both of these aspects are at the heart of each country's transformations towards democracy, peace, justice, and freedom. Under this framework, the chapters cover a diverse range of common issues, such as, minority grievances, gender inequality, ethnic identity, grassroots power in alliance-making towards community peace, recovery and resilience, digital freedom, democracy assistance and communication, and bridging multiple divides. As identity-based cleavages are daily lived experiences for individuals and communities, it requires grassroots initiatives and alliances as well as democratic communication to tackle obstacles at the root. Ultimately, the book convinces readers that social transformations must begin at the individual to communal level and local to national level. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
ABSTRACT
The coronavirus disease 2019 (COVID-19) epidemic has spread worldwide and the healthcare system is in crisis. Accurate, automated and rapid segmentation of COVID-19 lesion in computed tomography (CT) images can help doctors diagnose and provide prognostic information. However, the variety of lesions and small regions of early lesion complicate their segmentation. To solve these problems, we propose a new SAUNet++ model with squeeze excitation residual (SER) module and atrous spatial pyramid pooling (ASPP) module. The SER module can assign more weights to more important channels and mitigate the problem of gradient disappearance;the ASPP module can obtain context information by atrous convolution using various sampling rates. In addition, the generalized dice loss (GDL) can reduce the correlation between lesion size and dice loss, and is introduced to solve the problem of small regions segmentation of COVID-19 lesion. We collected multinational CT scan data from China, Italy and Russia and conducted extensive comparative and ablation studies. The experimental results demonstrated that our method outperforms state-of-the-art models and can effectively improve the accuracy of COVID-19 lesion segmentation on the dice similarity coefficient (our: 87.38% vs. U-Net++: 84.25%), sensitivity (our: 93.28% vs. U-Net++: 89.85%) and Hausdorff distance (our: 19.99 mm vs. U-Net++: 26.79 mm), respectively.
ABSTRACT
The Double Asteroid Redirection Test (DART) mission is NASA's first planetary defense mission to demonstrate the viability of kinetically impacting an asteroid and deflecting its trajectory. The DART spacecraft successfully launched on November 24, 2021 from the Vandenberg Space Force Base and successfully made impact on Dimorphos, the smaller asteroid in the Didymos system, on September 26, 2022. The DART spacecraft has one instrument called Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO). DRACO is an imaging telescope that, in conjunction with the SMART Navigation algorithm, autonomously guided the DART spacecraft to the asteroid. Because DRACO is a mission critical and light sensitive instrument, the DRACO Door mechanism was designed as the protective cover. The door functions to shield DRACO from stray light during launch, to deploy in space once when commanded, and to stay 180 degrees open for the duration of the mission. The DRACO Door went through several iterations during the design phase with decisions on various components such as Frangibolts ®, torsion springs, hardstops, and latches. After fabrication and assembly, the door went through a rigorous environmental testing plan, which included deployment testing, vibration testing, and thermal vacuum testing. After successful qualification of the mechanism, the door was installed and integrated into the DART spacecraft. It should be noted that during the fabrication of the mechanism piece-parts, the COVID-19 pandemic began, and the effects of the pandemic were seen in the challenges faced during the DRACO door assembly and testing. Under the constraints of the pandemic, the DART spacecraft was successfully built, tested, and launched, and the DRACO door was successfully deployed on December 7, 2021. The door has continued to function as intended. This paper will discuss the design choices behind the door components, the environmental qualification test program, and the installation of the door onto the DART spacecraft. In addition, this paper will discuss the lessons learned and the challenges of fabricating and testing the flight hardware. © 2023 IEEE.
ABSTRACT
COVID-19 triggered a monumental shift to remote work. The challenge of connecting and relating among knowledge employees emerged globally, and research about remote work in this unique circumstance surged. However, we know more about the impact of remote work on knowledge employees in low-context cultures than in high-context. Given that Brazil is high context, we explored how remote work impacted relating and connecting among knowledge employees in Brazil. First, employees lost the informality of work-life;instead of informal, fluid communication and collaboration, participants had to book appointments and schedule time to discuss simple issues. Second, good-humoured behaviours diminished, implicating connectedness. Third, non-verbal communication ceased, and employees lost facial expressions, eye contact, and other prevalent signs necessary for context. Fourth, the loss of unstructured exchange of experiences and ideas lessened tacit knowledge sharing. Fifth, workspace inequalities emerged as the employees' homes were unequipped for remote work. Lastly, the most significant win was work-life balance. Therefore, remote work in high-context cultures is not without peril;culture and socioeconomics underline remote work's self-generating, self-organizing mechanisms. Thus, corporate leaders and human resource professionals should address remote work as a layered phenomenon and, carefully, with employees, co-construct the notion of connecting and relating.

ABSTRACT
This paper is a personal attempt to rethink critically the social impact of the Covid-19 pandemic, trying to discuss about some changes, which came out in that tragic period, in the way of living time and space. There are several ways in which the COVID-19 pandemic has affected these two main structural dimensions of society and the response strategies used by people, groups, and social organizations, depending on the geographical area. There are trends that have had a highly differentiated impact, which have shown that the concept of time is not the same for everyone. Other trends have had a transversal impact, reconfiguring the ideas of present and future. Precariousness and uncertainty, that coincide with an existential specific condition of our contemporary, now take on a new meaning. Before the pandemic, the neoliberal development model seemed to have no alternative. Now, the possibility of an alternative model is imaginable, not only for the critics of it, but also for a large part of public opinion, which now even considers it necessary. The possibility of an alternative becomes concrete and achievable due to the impact that the Covid-19 pandemic has had on the structural dimensions of time and space in social life.
ABSTRACT
As a result of the rural exodus over the last decades, unused vacancies in rural areas are at risk of falling into disrepair. Given the current trends of flexible workplaces and people returning to rural areas, their repurposing as coworking spaces (CWSs) by entrepreneurs poses a potential for sustainable future-oriented workplace solutions. However, there is little to no guidance on the structural configuration and business models of CWSs in rural areas available for these entrepreneurs. We apply a structured empirical research approach to create a comprehensive and specialized taxonomy, including a literature review and eleven interviews with operators of rural CWSs in Germany. The resulting taxonomy of business models of CWSs in rural areas based on an extension of the business model canvas contributes to the knowledge base on rural CWSs. We evaluate its usability through a case study and an entrepreneurial operator of a rural CWS, underlining its entrepreneurial and practice-oriented purpose. The study addresses several urgent topics, such as the future of work and new work (places), which enable and accelerate the development of CWSs outside agglomerations consequential to the COVID-19 pandemic. It also promotes social and sustainable entrepreneurship and the revitalizing, enhancing, and increasing of digital accessibility of rural regions.
ABSTRACT
In recent years, the increasing social isolation has become a major problem in Japan because of the growing trend toward nuclear families. In addition, further social isolation is concerned caused by a decrease on face-to-face communication opportunities due to the outbreak of the COVID-19 infection. Therefore, it is necessary to create connections among people. On the other hand, opportunities for people to communicate online have increased rapidly. However, various information obtained the face-to-face is missing online, which degrades the quality of communication and causes physical and mental fatigue to users. To solve these problems, this study aims to minimize the gap that exists between online and the face-to-face, and to propose an Augmented Architectural Space that creates casual connections between people within their living space. By comparing the results of impression evaluation experiments using questionnaires for the face-to-face environment, the video conferencing system environment, and the proposed system environment, we demonstrate the usefulness of the proposed Augmented Architectural Space system for creating casual connections between people. © 2023, Association of American Publishers.

ABSTRACT
Objective: COVID-19 has emerged as a significant global health crisis causing devastating effects on world population accounting for over 6 million deaths worldwide. Although acute RTI is the prevalent cause of morbidity, kidney outcomes centered on a spectrum of AKI have evolved over the course of the pandemic. Especially the emerging variants have posed a daunting challenge to the scientific communities, prompting an urging requirement for global contributions in understanding the viral dynamics. In addition to canonical genes, several subgroup- specific accessory genes are located between the S and E genes of coronaviruses regarding which little is known. Previous studies have shown that accessory proteins (aps) in viruses function as viroporins that regulate viral infection, propagation and egress [1]. In this study we attempted to characterize the function of aps of coronavirus variants as ion channels. Furthermore, we also probed the interaction of ap4 with the host system. Method(s): Serial passaging (selection pressure), growth kinetics, confocal imaging, genome sequence analysis and proteomics were performed in Huh-7, MRC5 cells and/or human monocyte derived macrophages. Potassium uptake assay was performed in a Saccharo myces cerevisiae strain, which lacks the potassium transporters trk1 and trk2. Ion conductivity experiments were performed in Xenopus laevis oocytes using Two Electrode Voltage Clamp (TEVC) method. Result(s): Serial passaging demonstrated the acquisition of several frameshift mutations in ORF4 resulting in C-terminally truncated protein versions (ap4 and ap4a) and indicate a strong selection pressure against retaining a complete ORF4 in vitro. Growth kinetics in primary cells illustrated a reduction of viral titers when the full-length ap4 was expressed compared to the C-terminally truncated protein ap4a. Confocal imaging showed that ap4 and ap4a are not exclusively located in a single cellular compartment. Potassium uptake assay in yeast and TEVC analyses in Xenopus oocytes showed that ap4 and ap4a act as a weak K+ selective ion channel. In addition, accessory proteins of other virus variants also elicited microampere range of currents. Conclusion(s): Our study provides the first evidence that ap4 and other accessory proteins of coronavirus variants act as viroporins. Future studies are aimed at demonstrating the role of ap4 during the viral life cycle by modulating ion homeostasis of host cell in vivo (interacting proteins obtained from proteomic studies) and thereby serve as a tool for potential drug target.
ABSTRACT
This study utilizes the enclosed and stable environment of underground space for long-term sustainable planning for urban epidemics and disasters. Owing to the COVID-19 epidemic, cities require long-term epidemic-disaster management. Therefore, this study proposed a strategy for integrating multiple functions to plan a comprehensive Underground Resilience Core (URC). A planning and assessment methods of URC were proposed. With this methodology, epidemic- and disaster- URCs were integrated to construct a comprehensive-URC in underground spaces. The results show: (1) Epidemic-resilient URCs adopting a joint progressive approach with designated hospitals can rapidly suppress an epidemic outbreak. (2) The regularity of the morphology of underground spaces determines the area of the URC. Bar-shaped underground spaces have the potential for planning disaster-URCs. (3) The URC planning efficiency ranking is as follows: Bar shapes lead overall, T shapes are second under seismic resilience, and Cross shapes are second under epidemic resilience. (4) The potential analysis of planning a comprehensive-URC in the underground parking in Chinese cities showed that the recovery time can be advanced from 29% to 39% and the comprehensive resilience can be improved by 37.63%. The results of this study can serve as sustainable urban planning strategies and assessment tools for long-term epidemic-disaster management.
ABSTRACT
El ecosistema espacial mundial está en pleno crecimiento en cuanto al número de protagonistas y a volumen de negocio, tendencia que es imparable. La entrada en escena de actores privados en la exploración de cosmos con el beneplácito de las organizaciones espaciales gubernamentales y la futura explotación de los recursos existentes más allá de la Tierra va a crear un nuevo mercado de dimensiones incalculables. Todo ello está siendo posible gracias a las tecnologías disruptivas que, paso a paso, se van poniendo a punto. De forma paralela, en el ámbito castrense, cada año son más las Fuerzas Armadas en las que se produce la escisión de las estructuras espaciales de sus respectivos ejércitos. O la alternativa, que es la instauración de organizaciones especializadas en el seno de las Fuerzas Aéreas, procesos que también se prolongarán en los próximos años.Alternate :The global space ecosystem is in full growth in terms of the number of players and volume of business, a trend that is unstoppable. The entry on the scene of private actors in the exploration of the cosmos with the approval of government space organizations and the future exploitation of existing resources beyond the Earth will create a new market of incalculable dimensions. All this is being possible thanks to disruptive technologies that, step by step, are being perfected. In parallel, in the military sphere, each year there are more Armed Forces in which the division of the spatial structures of their respective armies is taking place. Or the alternative, which is the establishment of specialized organizations within the Air Force, processes that will also continue in the coming years.
ABSTRACT
This article deals with the return of the Passeio Cantante artistic action to the streets, after two years of social isolation caused by COVID-19, with the aim of leaving a testimony of the experience of the arts of presence and isolation. It adds a narrative about the language that has been created from the intersection between historical heritage, scene and June tradition, which here is called Teatro de Quermesse. To describe how this caipira theater has been made, we add to the information related to Passeio Cantante, information about the urbanization of Campinas since the 18th century, about the people and the June tradition planted here since the 16th century. From the material gathered here, we show how this dramaturgy for alleys, squares and squares is thought of as a scenic event that evokes the memory of the city, from a political perspective of today with a view to proposals for the future. The text dialogues with Leda Maria Martins (1997;2002), Milton Santos (2014), Luis Antonio Simas (2019), among other references.
ABSTRACT
This article deals with the change in the perception of public spaces due to the Corona pandemic. The focus is on the conversion of urban spaces through the construction of outdoor bar areas, a current and so far neglected issue from a scientific perspective. Against the background of the conceptual embedding of the concepts of public space and curb side dining areas (or synonymously: "Schanigärten”), the dealing with the latter in the study area of Munich is explained. In the context of the current situation in Munich, the influence of curb side dining areas on the perception of public space is first analysed by means of an explorative survey. The result of a conjoint analysis shows, among other things, a positive correlation between the presence of curb side dining areas and the perception of respective computer-simulated street scenes (with all possible combinations of the presence or absence of curb side dining areas, trees and parking spaces). In addition, a regression analysis is used to analyse the extent to which individual socio-demographic aspects (e.g., age, gender) and aspects of attitude (e.g., toward the conversion of urban parking lots) and behaviour (car use) influence perception. In a further step, specific street scenes are assessed using recent photographs from Munich in order to measure different aspects of perception as well. The evaluation of a semantic differential shows that street sections with "Schanigärten” are consistently perceived more positively (e.g. more interesting, safer, more inviting) than those without. Finally, and in the light of the Corona pandemic, the development of the "Schanigärten” in Munich is explained from an expert's perspective, before the article concludes with a summary and an outlook. © 2022 Austrian Geographical Society.

ABSTRACT
Not only is space use a result of spatial configuration, but it is also greatly determined by social patterns and society's living modes. The COVID-19 pandemic and confinement resulted, worldwide, in a 24/7 use of the domestic setting, which had to be adapted to the emergence of new needs and functions in the domestic space. The paper aims at understanding how COVID confinement altered domestic space use in Lisbon and how current society has maintained some of those changes, a reflection of new social patterns. The analysis is supported by an inquiry, carried out during the first confinement of 2020, in the city of Lisbon. Results show that domestic space use had to be adjusted to a new context, gaining new functions, and bringing into evidence the need for additional spaces. In light of the proven changes in living modes, the research concludes that the post-COVID home needs to be rethought and new housing programs should take into consideration the new social patterns and living modes. © 2023 by the authors.
ABSTRACT
With the use of blockchain, Internet of Things, virtual platform/telecommunications network, artificial intelligence and the fourth industrial revolution, the essential demand for digital transition within the health care settings has increased as an outcome of the 2019 coronavirus illness outbreak and the fourth industrial revolution. The evolution of virtual environments with three-dimensional (3D) spaces and avatars, known as metaverse, has slowly gained acceptance in the field of health care. These environments may be especially useful for patient-facing platforms (such as platforms for telemedicine), functional uses (such as meeting management), digital education (such as modeled medical and surgical learning), treatments and diagnoses. This chapter offers the most recent state-of-the-art metaverse services and applications and a growing problem when it comes to using it in the healthcare sector. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
In this essay, I lay out my motivations for doing publicly engaged sociology, emphasizing both the joys and the challenges of this work, and some of the key lessons that I have learned. I explore my attempts to impact policy at the federal level and the local level of my university, as well as efforts to shape changes across academia during the COVID-19 crisis. I have found it meaningful to be working toward all of these changes. Moreover, making sense of the spaces that I inhabit, collecting data, exploring patterns, and connecting it to social theory, has deepened my thinking as a sociologist, and bettered my research more broadly. © 2023 Eastern Sociological Society.
ABSTRACT
Understanding how to engage learners in a digital space is a growing issue facing many online instructors. Our interest in digital spaces as sites of engagement results from a pedagogical concern with how Zoom, a commonly used videoconferencing software program, fosters learners' engagement with their new digital tool, with the subject matter of the course, and with their instructor and peers. We assert that Zoom is not just a tool or place of learning but a social space regulating users' interaction that is imbued with their previous experiences, perceptions, and expectations. We examine how online engagement is co-constructed in university classrooms using Lefebvre's (The production of space. Blackwell, 1991) triad of "space" conceptual framework. Using examples from our teaching during the COVID-19 switch to the Zoom learning platform, we explain how different forms of engagement were realized in our English language and Linguistics courses. Our perspectives on using Zoom, with its affordances and challenges, may provide other educators with a practical insight into the various ways in which digital engagement can be facilitated. © Springer Nature Switzerland AG 2021.

ABSTRACT
The era of the COVID-19 pandemic affects almost all industrial sectors, including start-up industry. This research aims to provide an overview of branding strategy innovations conducted by the startup coworking space industry, "Ngalup", especially to deal with various problems arising from the impact of the COVID-19 pandemic. This study used qualitative methodology utilizing interview techniques to collect all the necessary data from informants. The main informants in this study were the Marketing Communication Manager and Internal Community Host of "Ngalup"Coworking Space, and the supporting informants were visitors and participants of "Ngalup"Coworking Space event. The results showed that the problem included decreased engagement on social media and decreased revenue due to the lack of visitor because some events or activities had to be shifted to online. To overcome this, "Ngalup"has tried to optimize omnichannel branding strategy, which is the integration of multichannel including online and offline to continuously improve the customer experience, such as optimizing their online media channels and programs, creating a new project 'Digarapin' as a new business model to gain revenue, and maintain the five-star hotel service. The research conluded that the branding strategy developed by "Ngalup"through omnichannel has helped "Ngalup"maintained the top coworking space in Malang and taken advantage of the development opportunities in the age of the COVID-19 pandemic. © 2023 Author(s).
