Adaptive thermal comfort models are increasingly utilized to condition thermal environments by considering occupants' adaptability. The most widely recognized models internationally are the ASHRAE 55-2020 and UNE-EN 16798-1:2020 standards, primarily applied in residential and office buildings. However, their use in heritage buildings such as museums has been very limited. These environments present unique challenges that complicate the implementation of conventional energy-saving methodologies due to restrictions on interventions in the buildings to safeguard their historical value. Therefore, it is essential to develop research that evaluates the applicability of these standards as an alternative strategy to the specific conditions of museums in heritage buildings in Spain. This study aims to explore the application of the international adaptive thermal comfort models of the ASHRAE 55-2020 and UNE-EN 16798-1:2020 standards in parallel with the preventive conservation conditions of the collections established by the UNE-EN 15757:2011 standard. The aim is to evaluate new strategies for environmental reconditioning to improve visitor comfort while ensuring the conservation of the collections in the exhibition spaces of the Museum of Popular Arts and Customs, housed in a 1914 building known as the Mudejar Pavilion in Seville. Field monitoring was conducted to assess the thermal environment and visitor comfort. The results revealed that the monitored environmental conditions of the exhibition spaces of the Mudejar Pavilion, in accordance with ASHRAE 55-2020 standards, showed high effectiveness in ensuring thermal comfort for visitors, achieving comfort 99% of the time annually, with an acceptability of 80%. High suitability for the conservation of collections was also observed, with optimal conditions achieved 87% of the time. However, under the standards of UNE-EN 15757:2011 for a Category III expectation level, comfort was only achieved 70% of the year, while stability of conservation conditions was achieved 88% of the time. Finally, the implementation of specific correction guidelines is proposed to achieve the acceptability limits of greater energy efficiency. [ABSTRACT FROM AUTHOR]

Community engagement has been identified as a key component for successful conservation efforts. According to community members, key stakeholders, and coral reef restoration practitioners in the Seaflower Marine Protected Area (MPA), the most effective way to engage communities in coral reef restoration is by building local capacity. We used a mixed‐methods approach including interviews, strengths, weaknesses, opportunities, and threats analysis, and surveys to assess strategies employed in the Seaflower MPA to involve local communities in coral reef restoration and the motivations and possible barriers that hinder community engagement. The community residing in the Seaflower MPA demonstrated awareness of the importance of coral reefs and their role in their livelihoods. They identified the main challenges to restoration as social dysfunctionality, administrative barriers, and environmental threats, along with a lack of opportunities for the community to participate in coral reef restoration. Our findings identified building trust, promoting equity, transparency, and accountability, fostering collaboration, and improving communication as essential to overcoming these challenges. Empowering local communities through capacity‐building initiatives such as educational programs, economic incentives, equity and inclusion measures, formal certifications, and local leadership would enhance support for coral reef restoration in the Seaflower MPA. In addition to building local capacity, our research identified the need for strategic planning, budgeting, and effective policies for enhancing community efforts in coral reef restoration.

Restoration of historical buildings requires an application of suitable and convenient materials which are compatible with historical legacy. On the other hand, the used materials have to show adequate durability and fulfil current tendencies of environmental-friendliness policy. Most historical buildings have their facades made of lime-based, or more precisely, blended-lime-based plasters. Metakaolin belongs to one of the most common representatives of pozzolanic admixtures used in this field. It is an artificial product, which arises by the calcination of kaolinitic clay or claystone at temperatures of about 550–900 °C. Like every other production process, a remarkable amount of waste rises also in the case of metakaolin. This study is aimed at the utilization of this waste, specifically the waste calcined shale (WCS). It is composed of not properly burned particles with varying compositions. Contrary to metakaolin, it contains a lower amount of amorphous phase and a higher amount of kaolinite and mullite. WCS was used in the production of lime-based plasters with a dosage of up to 50%. During the hardening, the carbonation process takes place in combination with the pozzolanic reactions. It gives rise to a higher amount of amorphous structures, about 15% in the case of pure lime contrary to up to 45% (in the highest dosage of WCS) and other crystal phases such as calcium-aluminate-carbonate hydrates. Obtained phase analyses are supported by the determination of SEM analysis and mechanical properties, which are also measured depending on time. [ABSTRACT FROM AUTHOR]

PURPOSE. Studies about success of FPDs (fixed partial dentures) mostly include restorations built by different clinicians. This results in limited comparability of the data. The aim of this study was to evaluate complications of all-ceramic FPDs built by 1 dentist between 2011 to 2023. MATERIALS AND METHODS. 342 all-ceramic FPDs were observed during follow-up care. 48 patients received 262 single crowns, 59 bridges and 21 veneers. Because of the different lengths of the bridges, units were defined as restored or replaced tooth. 465 units performed by the same dentist from Nov 2011 to Nov 2022 were included. Influencing factors "restoration", "construction", "abutment", "localization", "vitality" and "application period" were evaluated using Kaplan-Meier Analysis and Log-Rank Tests. RESULTS. 406 units (87.3 %) showed no complication. 7 correctable chippings (1.5 %) and 10 recementable decementations (2.1 %) occurred. Six decemented units got lost (1.3 %). 21 units failed due to fatal fracture (4.5 %). Crown margin complications, such as secondary caries, occurred in 15 units (3.2 %). Comparing the influencing factors resulted in higher complication rates of veneers (P < .001), of monolithic ceramics (P = .050) and of molar-restorations (P = .047). The application period had no influence on the success and survival rate. CONCLUSION. Overall, all-ceramic FPDs showed good clinical results. Although less complications were observed with modern restorations, these more often led to complete failure. To generate evidence-based recommendations, further studies are needed to evaluate the mid- and short-term success and survival of current all-ceramic restorations. [ABSTRACT FROM AUTHOR]

Designated as architect by Osman Hamdi, Alexander Vallaury designed the classical building of First Imperial Museum of Ottoman Empire (Müze-i Hümayun - İstanbul Archaeological Museums — IAM), erected between 1891 and 1907 in three phases. The IAM building sprouted inside the land walls of Topkapı Palace, which was built in the acropolis of the ancient Greek city Byzantion, just across from the ruins of the Great Palace of Byzantine Empire. This building is in a core area, symbolizing the imperial power of Roman, Byzantine, and Ottoman eras. Unlike previous studies, which examined mostly the building's architectural history, this study focuses on the time before its construction. It investigates the understructure remains by utilizing the original drawings and correspondences in the Museum Archive, which were made during the construction of second and third phases of the building in 1899–1907 at the end of the Ottoman Period. Through this investigation, it reveals the reciprocal relationship between the superstructure of IAM and the Byzantine substructure for the first time in the literature. All these sources were used to create a holistic site restitution of the museum buildings, covering old and newfound remains. [ABSTRACT FROM AUTHOR]

Climate change significantly affects the operating environment of buildings. These changes impact both energy efficiency and occupants' comfort and remain crucial even in building restoration, where design decisions typically rely on historical data, yet performance depends on anticipated future scenarios. The present work evaluates the impact of different climate datasets on dynamic energy simulations for an educational building in Central Italy, focusing on estimating heating demands across historical, current, and future climatic scenarios. The assessment considers both the building's current state and potential energy-efficient retrofits. Initially, various meteorological datasets, including measured and model-generated data, are selected to predict key weather parameters. The analysis reveals the potential and limitations of regional climate models (RCMs) in estimating these variables, with the MM5 dataset emerging as the most reliable. Subsequently, the energy performance of the reference building and its vulnerability to climate change are assessed. Our results show significant differences in energy demand based on construction periods, with the oldest section consuming 29% to 54% more energy monthly than the newer sections. Moreover, using non-representative climatic files can lead to prediction errors of up to 199%. Finally, the building's energy behaviour is analysed under future climate conditions by generating typical meteorological years (TMYs) for 2030, 2050, and 2070. This analysis evaluates the energy requirements for both existing and retrofitted building configurations. The findings confirm that retrofit interventions with high-performance insulation and upgraded windows significantly enhance the building's energy efficiency and resilience to future climate conditions, leading to annual energy savings of 50% to 57%.

Earthen architecture holds deep historical, cultural, and ecological value, forming an essential component of our global cultural heritage. However, these structures face numerous threats, including climate change, socio-economic shifts, and, in many cases, neglection, which accelerate their deterioration. This study introduces a photogrammetry-based methodology adapted for the digital documentation and preservation of earthen architecture within the context of developing countries. We focus on the Ex-Hotel Oasis Rouge in Timimoun, an iconic earthen building in southwestern Algeria and the current headquarters of CAPTERRE (Algerian Centre for Earthen Built Cultural Heritage). This paper details our approach to using photogrammetry to capture both the interior and exterior of the building, produce detailed orthophotos for archiving the unique earthen bas-reliefs, and conduct a condition assessment. Our findings demonstrate the effectiveness of photogrammetry as a cost-effective tool for heritage documentation, highlighting its potential to assist in the ongoing preservation and informed restoration of earthen architecture.

This article is a critical analysis of the conservation of a historic earth building: the Saint Bartholomew's Church in Nigeria. It presents the conservation actions carried out through the application of conservation principles adapted to local context and contributes to building knowledge regarding building conservation in Africa. The conservation actions consisted of diagnostics, technical interventions and developing guidance for future maintenance of the building. The conservation was carried out between August 2021 and April 2023. A dualistic approach that combines local resources and internationally acceptable conservation practices was employed in the conservation of the church. This approach ensured that the appropriate interventions were carried out on the church building fabric simultaneously with training and knowledge exchange between experts from Nigeria and the UNESCO World Heritage site in Djenne, Bamako, Mali. This article highlights the challenges of conserving earthen architectural conservation in the 21st century and how these challenges can be mitigated through repair and documentation.

The COVID-19 pandemic has significantly altered how people work, with an increasing number transitioning to working from home (WFH). This paradigm shift has raised various challenges in adapting living spaces to meet the needs of remote work. Dedicated workspaces or home offices need to be customized for creativity and productivity. Thus, this systematic literature review explores the potential challenges and limitations of implementing modern office design features in residential environments. The study synthesizes findings from 108 peer-reviewed articles published within the last decade, focusing on ergonomics, productivity, work–life balance, and spatial constraints. The study found several challenges in translating office design features to home settings. Firstly, spatial limitations in residential areas often restrict the implementation of open-plan layouts and collaborative zones, which are hallmarks of modern office designs. Secondly, the integration of ergonomic furniture and adjustable workstations are limited by budget constraints and the dual-purpose nature of many home spaces. Furthermore, the review highlights the psychological challenges of maintaining work–life boundaries when professional and personal spaces overlap. Noise pollution and distractions emerge as significant factors impacting productivity in home offices, which contrasts controlled modern office environments. The review suggests that the complete replication of modern office design in homes may be impractical; a hybrid approach that adapts key features to residential constraints could enhance home office productivity. Potential solutions could include modular furniture designs, the simulation of collaborative spaces, and the development of noise-cancelling technologies specifically for home environments. This study contributes to the growing body of knowledge on remote work environments and provides valuable insights for enhancing work–life balance, environmental sustainability, and economic growth.

Plans for expanding protected area systems (prioritizations) need to fulfill conservation objectives. They also need to account for other factors, such as economic feasibility and anthropogenic land‐use requirements. Although prioritizations are often generated with decision support tools, most tools have limitations that hinder their use for decision‐making. We outlined how the prioritizr R package (https://prioritizr.net) can be used for systematic conservation prioritization. This decision support tool provides a flexible interface to build conservation planning problems. It can leverage a variety of commercial (e.g., Gurobi) and open‐source (e.g., CBC and SYMPHONY) exact algorithm solvers to identify optimal solutions in a short period. It is also compatible with a variety of spatially explicit (e.g., ESRI Shapefile, GeoTIFF) and nonspatial tabular (e.g., Microsoft Excel Spreadsheet) data formats. Additionally, it provides functionality for evaluating prioritizations, such as assessing the relative importance of different places selected by a prioritization. To showcase the prioritizr R package, we applied it to a case study based in Washington state (United States) for which we developed a prioritization to improve protected area coverage of native avifauna. We accounted for land acquisition costs, existing protected areas, places that might not be suitable for protected area establishment, and spatial fragmentation. We also conducted a benchmark analysis to examine the performance of different solvers. The prioritization identified 12,400 km2 of priority areas for increasing the percentage of species’ distributions covered by protected areas. Although open source and commercial solvers were able to quickly solve large‐scale conservation planning problems, commercial solvers were required for complex, large‐scale problems.. The prioritizr R package is available on the Comprehensive R Archive Network (CRAN). In addition to reserve selection, it can inform habitat restoration, connectivity enhancement, and ecosystem service provisioning. It has been used in numerous conservation planning exercises to inform best practices and aid real‐world decision‐making. [ABSTRACT FROM AUTHOR]

This paper outlines a research project on the use of wood tar as adhesive for architectural stone repairs. Tar was identified as having been used in medieval repair techniques on Stavanger cathedral in Norway, as well as on several other medieval cathedrals in England and Germany. The hypothesis is that a complex adhesive mixture based on wood tar was manufactured and strategically employed by medieval artisans in northern Europe as stone repair material. Given that such repairs have withstood centuries of wear, there must have been extensive material knowledge and awareness of the complex requirements of structural adhesives. These historic tar repairs created the impetus for a research project, the aim of which is to rediscover the lost medieval art of traditional stone repair using wood tar adhesives, recreate the historic adhesive and repurpose it for modern conservation practice. By reintroducing traditional wood tar adhesives based on natural renewable source materials, we could potentially reduce dependence on synthetically manufactured adhesives. Thus, newly-discovered medieval techniques which have successfully lasted centuries will be drawn on to help solve the limited selection of suitable adhesives for stone conservation, contributing to future preservation of stone architecture and the built heritage environment.

To create a resilient environment, adaptive reuse of old buildings is becoming rampant through renovation, restoration, or refurbishment. Although such efforts bring advantages by preserving heritage assets while accommodating current needs, the challenges involved in this type of project are compelling. Therefore, this study is focused on assessing the risk level of common challenges in historic building renovation and restoration projects. By conducting a survey of industry practitioners, this study identified that the common challenges have a higher average frequency than their corresponding severity rankings. Also, the survey responses indicated schematic design estimates should include the highest contingency. This study has contributed to the body of knowledge in the adaptive reuse of buildings and risk management research domain by revealing the risk level of challenges in historical building renovation and restoration projects. Moreover, this study allows industry practitioners to better manage this type of project by understanding the relative frequency and severity of common challenges. [ABSTRACT FROM AUTHOR]

In recent years, motivated by widespread declines in wild bees, ecologists have prioritized learning about patterns of wild bee communities across the landscape at the expense of learning about the population‐level mechanisms driving those patterns. In this essay, we seek to revitalize the tradition of studying wild bee populations in a way that both contributes key knowledge for bee conservation and builds a strong conceptual understanding of the processes underpinning bee populations. We address two widespread concerns about investing in population‐level research. First, that population‐level studies are too conceptually narrow to provide broad inference. If population‐level studies are couched in general ecological theory, then findings from a single species can be generalized to many. We highlight how wild bees would make excellent candidates for exploring five areas of general ideas in population ecology, including nutritional ecology, drivers of vital rates, phenology and voltinism, habitat selection, and movement. Second, we address the concern that methods for studying bees at the population level are too difficult to implement. Methods for conducting population‐level studies of bees—specifically, identifying living bees in the field and studying individuals throughout their life cycles—are feasible to implement at the scales appropriate for answering population‐level questions, for example, a few species at a few sites. To facilitate adoption of these ideas, we developed an online field guide (www.watchingbees.com) and a detailed methods manual. More generally, we emphasize the value of linking data‐rich pattern‐oriented approaches in ecology with an understanding of the basic biology and mechanisms that generate those patterns.

Modern heritage, especially post-war housing estates, is facing the problems of appreciation and preservation. These buildings are interpreted in different ways by decision-makers because of questions relating to their identification. Accordingly, this research aims to better understand the heritage attributes and significance of post-war housing estates, in particular in the Yenişehir settlement—a neighborhood in Karabük, Türkiye. Within the framework of cultural significance and heritage values (values of DOCOMOMO), an assessment was conducted by using expert interviews for data collection. The AHP (analytical hierarchy process) method, one of the decision support systems, was used to contribute to the subjective decision process. The experts determined significance levels for the studied buildings based on whether they needed to be preserved. Comparisons with the AHP created essential data that showed different views, especially regarding intangible values. Through the process, the attributes and values of buildings were made visible. According to experts, the significance of the buildings has changed. This study consists of 5 stages: authenticity analysis of the buildings in the area, classification of the buildings, application of the AHP on buildings of greater significance, determining of cultural significance ranking, and making suggestions according to the ranking.

The roofs of heritage buildings are subject to long-term degradation, resulting in poor heat insulation, heat regulation, and water leakage prevention. Researchers have predominantly employed feature-based traditional machine learning methods or individual deep learning techniques for the detection of natural deterioration and human-made damage on the surfaces of heritage building roofs for preservation. Despite their success, balancing accuracy, efficiency, timeliness, and cost remains a challenge, hindering practical application. The paper proposes an integrated method that employs a convolutional autoencoder, thresholding techniques, and a residual network to automatically detect anomalies on heritage roof surfaces. Firstly, unmanned aerial vehicles (UAVs) were employed to collect the image data of the heritage building roofs. Subsequently, an artificial intelligence (AI)-based system was developed to detect, extract, and classify anomalies on heritage roof surfaces by integrating a convolutional autoencoder, threshold techniques, and residual networks (ResNets). A heritage building project was selected as a case study. The experiments demonstrate that the proposed approach improved the detection accuracy and efficiency when compared with a single detection method. The proposed method addresses certain limitations of existing approaches, especially the reliance on extensive data labeling. It is anticipated that this approach will provide a basis for the formulation of repair schemes and timely maintenance for preventive conservation, enhancing the actual benefits of heritage building restoration.

Rehabilitating heritage buildings is a common practice in developed countries. In contrast, developing countries experiencing conflict lack the financial support and qualified experts to restore heritage buildings. This article focuses on the restoration of the al-Khader building in the Gaza Strip, part of a UNESCO project aimed at preserving historical buildings. This study aims to explore the challenges and impacts of the adaptive reuse of the al-Khader building as a children's library for the local community and to explore the impact of this project on sustainable development and its importance locally, as well as the role of this building restoration and rehabilitation through Quintuple Helix dimensions. Qualitative methodology was used, including field observation and interviews, to present the project stages during restoration in 2016. The interviews were conducted with library users, employees, and visitors to evaluate their experience in 2019. The research revealed that the restoration process faced several challenges, including a lack of experience and professional workers in conservation work. Despite challenges, the building's transformation positively affected heritage preservation and the local community, aligning with 11 Sustainable Development Goals—directly with 7 goals (SDGs 4, 7, 8, 11, 12, 16, and 17) and indirectly with 4 goals (SDGs 1, 5, 9, and 13). The findings emphasise the role of the library's rehabilitation in contributing to the success of the Quintuple Helix in economic and civil society systems and the need to enhance the consideration of government, education, and environmental systems. Finally, this project, which external donors funded, increased awareness among local people of the importance of heritage buildings. Unfortunately, due to the ongoing conflict in Gaza, the current status of the building is unknown. This study, therefore, serves as necessary documentation of the building as it was in 2023 and prior. [ABSTRACT FROM AUTHOR]

Some wrong decisions and faulty practices applied during the repair and restoration of traditional buildings cause more damage to the structures due to the materials used in the repair. The aim of this study is to establish a scientific basis for material selection in the repair of traditional buildings in the Konuralp region through chemical and petrographic analyses. In this study, brick, mortar, plaster, and wood samples were taken from one registered building in the Konuralp neighborhood of Düzce Province that has survived to the present day by preserving its original structural features and reflecting the characteristics of traditional housing. Chemical and petrographic analyses were carried out on the samples. In line with these analyses, a scientific basis was created for selecting material properties in the repair and reuse processes of traditional buildings and suggestions are made for the analysis of materials specific to traditional buildings in Konuralp.

In this study, we focus on Coenonympha oedippus, an endangered butterfly species protected under Annexes II and IV of the EU Habitats Directive. Predominantly inhabiting semi‐open wet grasslands across Europe, this species also occupies abandoned sub‐Mediterranean dry grasslands. Ecological distinctiveness in its habitat use is reflected in differences in larval host plants, wing morphology and genetic composition, resulting in two ecotypes: wet and dry. Notably, by 2018, only one population of the wet ecotype survived in Slovenia, necessitating reintroduction as a critical strategy to avert its national extinction. Building on our conservation objectives, we implemented a 5‐year project (2018–2022) to develop protocols for source individual and substrate collection, ex situ breeding in semi‐natural conditions, thorough release and post‐release monitoring. Our efforts included breeding from 18 females, yielding 754 eggs in a breeding house. From these, we successfully reared and released 460 individuals, comprising 419 pupae and 41 butterflies. The project culminated with promising outcomes: the reintroduced population exhibited an 87% growth rate, while the source population, following its last reinforcement, showed a 79% increase. The project success can be attributed to a comprehensive understanding of species' ecological requirements and the establishment of a long‐term management plan. Key to our approach was adaptive management, which allowed for flexibility and refinement of protocols during implementation. Meticulous documentation and evaluation of all project activities were instrumental, culminating in the production of standardised annual reports. Additionally, the project was bolstered by strong collaboration among scientists, site managers, government agencies and national media. [ABSTRACT FROM AUTHOR]

As a unit of measurement for Chinese ancient construction, the yingzao chi (yingzaochi 营造尺) is of great significance to study long-term transformation of culture, construction skills, and the scale design rule of Chinese regional architectural heritage. But few scholars study the restoration method of the yingzao chi of palace buildings sans dougong (斗拱) in Chinese Ming and Qing Dynasties. Based on the yingzao chi theory, this paper studies and improves a theoretical method to help restore the yingzao chi of palace buildings sans dougong in Ming and Qing Dynasties. This method is not limited by the lack of reference of vernacular chi (xiangchi 乡尺) and can restore the yingzao chi of a single building through surveying data, and there is a smaller error in the calculation process. Three typical palace buildings without dougong in Ming and Qing Dynasties in Chongqing are selected as examples. The results show that the restored yingzao chi of these three buildings is highly similar, most likely 320.7–323.6 mm, which can verify the reliability of this method. This study can help to improve the research of yingzao chi and provide theoretical support for the protection of this kind of architectural heritage. Besides, the restoration of the yingzao chi provides a potential opportunity to explore how the technological and cultural of palace architecture spread, develop and blend. [ABSTRACT FROM AUTHOR]

Historical buildings carry the key technologies and practical values throughout the development of architectural heritage. Investigating the restoration techniques for historical buildings under various forms of damage is an essential step in the conservation and utilization of these structures. Utilizing Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) as the primary databases, this study employs the PRISMA methodology to search and screen relevant research literature. A comprehensive review of the retained literature is conducted, analyzing publication trends, co-citation networks of authors and keywords, among other characteristics. To enhance the visibility of restoration techniques, three-dimensional modeling diagrams are created using actual case information of material or component damage as a reference, thereby increasing the referential value of the review content on historical building restoration techniques. The study provides a thorough review of over 30 restoration techniques corresponding to 9 types of damage from the perspectives of historical building walls and wooden components. Additionally, new materials or technologies mentioned in the retrieved literature are categorized; for instance, in the context of moisture-proof treatment for brick masonry, traditional methods are explained, and new research on electrochemical desalination and lipid-based waterproof materials is discussed and evaluated. Finally, given the multifaceted value and the variable mechanisms of damage in historical buildings, an analysis of the restoration process and techniques reveals that the restoration of historical buildings is a complex interdisciplinary process. The development and implementation of restoration plans should adhere to the principles of cultural relic protection to ensure their reasonableness and effectiveness, while also considering sustainability and environmental adaptability to protect and reuse historical buildings, thus leveraging their cultural and historical values. Moreover, the advancement of restoration techniques for historical buildings in the future should be based on the inheritance of traditional craftsmanship and materials, while also integrating new technologies, materials, and concepts to enhance the applicability and efficiency of traditional techniques.

Background: The strength of historical buildings built in different centuries with various materials and construction techniques and harboring many structural problems depends on the structural system, geometrical condition, and material properties. Sungurlu clock tower, whose system and geometry are in good condition, has been damaged under environmental and climatic effects, earthquakes, and other loads, and has survived to the present day by preserving its structural integrity to a great extent with the repairs it has undergone. Methods: In addition to static analysis, the robustness and durability of the design of the tower were tested by dynamic analysis with the SAP2000 program. In the model that will represent the actual system behavior of the tower, the lengths of the elements; nodal points; bearings; joints; shapes such as bars, shells, and plates; characteristic values of the materials to be used; as well as the system, element sections, and all loads and combinations of masses or dynamic forces acting on the system are defined. Results: In the reports presented visually, the moment, shear force, axial forces, and other forces to which the tower was exposed after the architectural and structural problems were eliminated were seen in a diagram. Since the effects of the damage could not be predicted, in this study, to measure the reaction of the building against earthquakes and other loads, the numerical model representing its original condition was prepared and analyzed according to the theoretical method and assumptions made by the restitution, survey, and static observation reports. Conclusions: With this program, which allows for the preparation of this model, it was concluded that the loads coming to the structure according to the principles of ductility, rigidity, and strength could be safely transferred to the ground without causing damage to the structural system and its elements. From the deformation, stress, velocity, acceleration, and reaction force graphs obtained, it was understood that the tower exhibited the expected structural behavior under its own weight and live loads. The stress and reaction force graphs showed that the structural materials are adequate for the resistance of the structure and system against the existing loads and possible earthquakes.

This study advances the understanding of the mechanisms that link past challenge and hindrance stressors to resilience outcomes, as indicated by emotional and psychosomatic strain in the face of current adversity. Building on the propositions of Conservation of Resources Theory and applying them to the challenge-hindrance framework, we argue that challenge and hindrance stressors experienced in the past relate to different patterns of affective reactivity to current adversity, which in turn predict resilience outcomes. To test these assumptions, we collected data from 134 employees who provided information on work stressors between April 2018 and November 2019 (T0). During the first COVID-19 lockdown (March/April 2020), the same individuals participated in a weekly study over the course of 6 weeks (T1–T6). To test our assumptions, we combined the pre- and peri-pandemic data. We first conducted multilevel random slope analyses and extracted individual slopes indicating affective reactivity to COVID-19 adversity in positive and negative affect. Next, results of path analyses showed that past challenge stressors were associated with lower affective reactivity to COVID-19 adversity in positive affect, and in turn with lower levels of emotional and psychosomatic strain. Past hindrance stressors were associated with greater affective reactivity to COVID-19 adversity in positive and negative affect, and in turn to higher strain. Taken together, our study outlines that past work stressors may differentially affect employees' reactivity and resilient outcomes in the face of current nonwork adversity. These spillover effects highlight the central role of work stressors in shaping employee resilience across contexts and domains. [ABSTRACT FROM AUTHOR]

Mortars are among the most important materials in building construction. They are generally obtained by mixing aggregates with an inorganic binder. The identification of mortar constituents, particularly the binder type in historic buildings, is one of the essential aspects of building conservation, considering that the new conservation materials must be chemically, mechanically, and physically compatible with the old masonries. Among other techniques used to characterise binders, those related to optical and electronic microscopy are particularly important. Microscopy and combined techniques may be the key to this identification since the classic mineralogical and chemical-based identification approaches are not conclusive enough in investigating the types of hydraulic binders in mortars. This work presents an analysis procedure to identify mortar binders by combining EDS microanalysis and petrography. Mortar samples of known composition were used as a reference for analyzing mortars from historic buildings. The proposed methodology made it possible to identify the type of binder or a mixture of binders based on the identification of the binder features by petrography together with analysis of the chemical composition of the paste by X-ray microanalysis under a scanning electron microscope.

Beijing is a typical traditional city in China, originating from the uniform and conventional grid plan, but transformed diversely, either on purpose or spontaneously. This research took the diversification process of grid blocks as an angle to understand the transformation process of Beijing's urban morphology. It took 194 grid blocks within the 3rd Ring Road of Beijing as research objects. First, the paper proposed a whole view of Beijing's grid blocks by 1) visualizing their construction process, 2) classifying 5 morphological clusters by 7 indicators (Block size, Block shape regularity, Intensity, Coverage, Network density, Plot shape regularity, Standard deviation of plot size), and 3) investigating their distribution. Second, the diversification process of grid blocks was clarified from two layers: the block-boundary layer and the inner-space layer. Finally, the mechanism of block form diversification was clarified by exploring the connections between elements in each layer, and the influence of urban development on block form transformation. The study re-defined the diversification process in a more quantitative way from both time and spatial dimension. It concluded that the diversification is influenced by changes in urban planning principles and locations, and emerged thorough the long-term transformation and re-subdivision. The interaction between the boundary and the inner space stimulates the diversification. And based on these, it concluded with a discussion of limitations and potentials on grid blocks' construction and renovation. [ABSTRACT FROM AUTHOR]

Pollen is becoming an increasingly important subject for molecular researchers in genetic engineering, plant breeding, and environmental monitoring. To broaden the scope of these studies, it is essential to develop accessible methods for scientists who are not specialized in palynology. The article presents a simplified technical procedure for preparing pollen grains for scanning electron microscopy (SEM). The protocol is convenient for any molecular laboratory due to its small set of reagents, ease of execution, low cost, does not require special equipment, and takes only one hour to complete. The high penetrating ability of formaldehyde and the final delicate dehydration using hexamethyldisilazane (HMDS) instead of critical point drying allow for sufficient preservation of the architecture of the aperture, which is considered a gateway for the passage of biomolecules. The method was successfully applied to pollen grains of representatives of dicotyledons (beetroot, petunia, radish, tomato and tobacco) and monocotyledons (lily, onion, corn, rye and wheat). Species studied included insect-pollinated (entomophilous) and wind-pollinated (anemophilous) species. A comparative analysis of the sizes of fresh living pollen grains under a light microscope and those prepared for SEM showed some shrinkage. Quantitative analysis of the degree of pollen grain shrinkage showed that this process depends on the initial shape of dry pollen grains, and the number and structure of apertures. The results support the theoretical model of the folding/unfolding pathways of pollen grains. [ABSTRACT FROM AUTHOR]

Traditional courtyard-style timber building is a type of typical architectural timber heritage with special structures, which is different from traditional timber building unit. This paper proposes a scientific and effective assessment method for the structural safety status of traditional courtyard-style timber buildings. Firstly, based on the Improved Analytic Hierarchy Process (IAHP) which introduces the calculation method of component importance, the quantitative weights of components in traditional courtyard-style timber buildings are obtained. Secondly, the structural safety status evaluation system, the evaluation indexes and the evaluation weights are established based on the consideration of the structural characteristics of courtyard-style timber buildings. Finally, through on-site investigation and structural analysis, the structural safety status of a typical traditional courtyard-style timber-frame building — the Chu Hsi's Public Granary, is studied to provide a basis for the subsequent conservation of the building. In addition, a quantitative automated security assessment software for courtyard-style timber buildings is developed. The study results can provide a reference for the safety assessment and preventive conservation of traditional courtyard-style timber building. [ABSTRACT FROM AUTHOR]

The Sakyamuni Pagoda of Fogong Temple, also known as the Yingxian Wooden Pagoda or the Wooden Pagoda of Ying County, is China's oldest and tallest wooden pagoda. This pagoda was constructed in 1056 and has faced many challenges, including earthquakes, wars, and mistreatment. However, it is currently in danger of potential collapse due to severe structural challenges. Preserving this historic monument requires interdisciplinary collaboration across architectural history, materials science, and engineering. This paper proposes the development of a parametric model to build the pagoda that can be used for future preservation efforts. While not precisely reflecting the pagoda's current condition, with the changes in inputs, the geometries of the structural members can be updated in real time, which offers adaptability crucial for preservation efforts. With the understanding of the original construction techniques, including its leaning column systems, the model not only helps preservation but also reveals the creativity of the architects or the craftsmen at the time. The 3D model, which includes more than 32,000 pieces along with the parametric files that can generate the column grid and dougongs, has been published along with this paper, and those files are available in the Data Availability Statement. In summary, the full digital model presented alongside this paper, unavailable elsewhere to the general public, serves as a practical preservation tool that can also be used for raising awareness for this cultural heritage site.

Fire is generally recognized as a major threat to the protection of historic timber architecture. Thus, there is an urgent need to study the fire properties of historic timber structures so as to better protect them in the future. Two types of commonly used wood species (pine and poplar) were selected as test specimens and three types of surface treatments (Chinese traditional coating, modern flame retardant, and a combination of the two methods) were applied. The specimens were subjected to a semi-full-scale fire test. The charring rate and the surface heating curve were calculated during the fire test to assess the flammability of various woods under different treatments. Results showed that the fire properties of traditional-coated wood were better than the modern type, but large amounts of smoke were released during combustion. The combination of traditional and modern methods did not significantly improve the overall fire properties and was even worse than the traditional treatment alone. At the same time, the fire properties of the modern method are highly correlated with the type of wood species used. The above results can provide informative advice on the selection of suitable surface treatments for the subsequent restoration of ancient buildings. [ABSTRACT FROM AUTHOR]

Building information modeling (BIM) can greatly improve the management and planning of historic building conservation projects. However, implementing BIM in the heritage has many challenges, including issues with modeling irregular features, surveying data occlusions, and a lack of predefined libraries of parametric objects. Indeed, surface features can be manually distinguished and segmented depending on the level of human involvement during data scanning and BIM processing. This requires a significant amount of time and resources, as well as the risk of making too subjective decisions. To address these bottlenecks and improve BIM digitization of building geometry, a novel deep learning based scan-to-HBIM workflow is used during the recording of the historic building in historic Jeddah, Saudi Arabia, a UNESCO World Heritage site. The proposed workflow enables access to laser scanner and unmanned aerial vehicle imagery data to create a complete integrated survey using high-resolution imagery acquired independently at the best position and time for proper radiometric information to depict the surface features. By employing deep learning with orthophotos, the method significantly improves the interpretation of spatial weathering forms and façade degradation. Additionally, an HBIM library for Saudi Hijazi architectural elements is created, and the vector data derived from deep learning-based segmentation are accurately mapped onto the HBIM geometry with relevant statistical parameters. The findings give stakeholders an effective tool for identifying the types, nature, and spatial extent of façade degradation to investigate and monitor the structure. [ABSTRACT FROM AUTHOR]

This study investigates the enhancement of hydraulic lime mortar (HLM) using varying contents of metakaolin (MK) to improve its application in the restoration of historic buildings. Samples from historic structures were analyzed, and the effects of different MK contents on the physical and mechanical properties of HLM were examined. The reaction mechanism and microstructural changes were evaluated using XRD and SEM analysis. The results indicated that increasing MK levels in HLM led to a decrease in fluidity, with fluidity reducing by 4.8% at 12% MK. The addition of MK increased water consumption for standard consistency by 5.4% and shortened the final setting time by 10.2%. MK consumption promoted secondary hydration, enhancing compressive strength by up to 98.1% and flexural strength by up to 55.1%, and increasing bonding strength by 26.9%. The density of HLM improved with MK addition, slightly reducing moisture content by 4.5% and water absorption by 4.6%, while the water vapor transmission properties decreased by 50.9%, indicating reduced porosity. The elastic modulus of the mortar increased significantly from 2.19 GPa to 7.88 GPa with the addition of MK, enhancing rigidity and crack resistance. The optimal blend for restoration materials was found to be 9.0% MK and 25.0% heavy calcium carbonate and was characterized by moderate mechanical strength, enhanced early strength, commendable permeability, minimal risk of cracking, and ease of application. This blend is highly suitable for the rehabilitation of historic structures. [ABSTRACT FROM AUTHOR]

Heritage buildings are crucial for any area's cultural and political aspects. Proper maintenance and monitoring are essential for the conservation of these buildings. However, manual inspections are time‐consuming and expensive. We propose a deep learning–based detection framework to identify the damages on the ancient architectural wall. The algorithm applied in this study is YOLOv5. Comparing its five different versions, it was decided to use YOLOv5m as the most accurate detection algorithm with a mAP of 0.801. The damage types identified are physical weathering and visitors' scratches. High‐resolution images were selected for the experiment and effectively identified image. In addition, the applied algorithm allows real‐time detection and the identification of seasonal sources of disruption, which is proved by the video test in this study. The findings contribute to the development of an intelligent tool for health monitoring with the goal of fast and remote damage detection in the routine maintenance of heritage buildings.

Heritage not only concerns old buildings, but also the layered quality of historic places. These are buildings or sites that help create a sense of value, discovery, and mystery that can lead to increased levels of place attachment. The Ōtātara site in Hawke's Bay is one of the oldest villages in New Zealand with strong historic, cultural, and spiritual associations with local indigenous Māori. In 1975, an arts program was established there in an attempt to connect modern knowledge with tradition. Although the program has since moved, the cultural and social associations are still present, linked to the only remaining building, a log cabin that has been refurbished to create a new layer of values by showcasing sustainable building design. This article investigates the factors that explain people's attachment to a heritage place, including the Māori population's unique connections to land, while engaging in designing a sustainable project that looks to the future. A series of interviews were conducted with those involved to understand the influence of the psychological and cultural dimensions of making places based on sustainable building. Place attachment emerged as a theme in the analysis as the interviewees highlighted the inspirational power of the historic and cultural dimensions in addition to the natural and ecological factors.

• The paper presents deep learning models to detect damage typology in patterned tiles. • Images of 5 classes of patterned tile damages were collected and annotated. • A new procedure based on a deep learning is proposed for damage detection in tiles. • Limitations in detecting damages on patterned tile surfaces are discussed. A prominent feature in Portuguese historic architecture is Portugal's azulejos or tiles that cover cultural heritage buildings with colorful patterns. However, tiles are prone to deterioration due to the quality of masonry materials, exposure over time, and natural and human factors. A careful approach is necessary to detect and assess tile damage in time to conserve cultural heritage. Deep learning (DL) methods are applied to detect deterioration and damage by automating vision-based monitoring. This study uses the You Only Look Once (YOLO), method to detect deterioration in tiles automatically. To obtain the initial dataset, over 5000 images of damage were collected, including cracks, craters, glaze detachment, and tile lacunae, as well as images with no defects. Additionally, a MobileNet model was used for binary classification of damaged and intact tiles to compare classification and detection approaches. Through the fine-tuning of hyperparameters and updating the dataset, an overall accuracy of over 72% for YOLO (multiple classification) and 97% accuracy for binary classification was achieved, demonstrating the adequacy of the tool for real-world applications.

The evolution of indigenous architecture for any social culture is usually sectionalised into thresholds of different but succinct architectural styles. The continued survival of any indigenous style is the ability to accommodate changes in components while preserving the culture of the people. The postmodern and contemporary architectural styles are the most recent defined patterns that have been assimilated into the Yoruba areas of Southwest Nigeria. Existing literature on Yoruba architecture have not addressed the delineation of the current threshold of the indigenous style. In a bid to address this problem, this research set out to define the current outlook of the Yoruba indigenous architecture through the forms and elements that have been acculturised from the foreign styles. This was achieved by locating the study in a historic city centre where the social culture is preserved in the community and the buildings. Urban upgrades carried out in the area stimulated the renovation and fresh construction of buildings where they occurred in the otherwise sedentary community. The older buildings in the sedentary parts of the study area and the newer structures in the upgraded areas provided two different thresholds in the architectural evolution for comparison of the constituents of the building patterns. After defining the study area, building counts were carried out to determine numbers in the upgraded and sedentary areas. This helped to calculate the sample sizes for direct observation guided by a schedule. Questionnaire was administered to evaluate residents' opinions on the subject. Descriptive statistics were used to identify the trends in typologies and preferences while existing literature was used to explain the chronology of styles and the architectural evolution of the area. The research identified the current natures of the forms and elements being adopted in the area and the reasons for their adoption. It concluded that the forms have been modified to suit the social culture and the climate. [ABSTRACT FROM AUTHOR]
