The De Tjolomadoe Museum was originally a sugar factory which later underwent a revitalization after being neglected for 20 years by carrying out the concept of adaptive reuse. After the revitalization was completed, the building was reopened as a museum along with various other supporting functions. The widespread use of social media such as Instagram among the public, the De Tjolomadoe Museum also uses Instagram as a medium to interact and attract the attention of the wider community to visit this museum. As a result, many people are interested in visiting and documenting it through photos which are then uploaded to social media and uploaded by tagging the official Instagram account @detjolomadoe_official. This study aims to find the effect of photo composition on the architecture of the De Tjolomadoe Museum by uploading the Instagram photo tag @detjolomadoe_official. This research focuses on the exterior of the museum through photos tagged on the Instagram account @detjolomadoe_official. Photos are taken via screenshots which are then processed by classifying them based on the composition used. The research is continued with analysis and discussion in accordance with related theories. The discussion starts with photo composition preferences, layers in photos, and building elements that appear in photos. The photos obtained were able to strengthen the character of the De Tjolomadoe Museum into a monumental building because of its compositional arrangement.

Actualising social sustainability through adaptive reuse innovations within the context of sustainable development

Sustainable Development (SD) is characterised of social, economic, and environmental components; however, the social component of SD has received little attention from academics, but recently, this has changed as the notion that growth is incomplete without equity gained more traction. One way to achieve the UN Goal 16 of ‘Promoting peaceful, just, and inclusive societies’ is through the concept of adaptive reuse innovation. Therefore, this paper aims to identify how the adaptive reuse concept has promoted the social sustainability concept through a systematic literature review (SLR). The SLR is necessary to summarise available evidence on the social sustainability potential of the adaptive reuse (AR). It further serves to create awareness of the reuse of building as an inclusive innovation critical for sustainable development. Using SLR, 56 relevant studies were extracted from the web of science and Scopus databases. A content analysis of five identified themes from the studies showed that adaptive reuse contributed to social sustainability through provision of social infrastructure, social cohesion, enhancing social health/well-being. There is need to advance research in areas of human adaptability, social awareness, and education on adaptive reuse.

A definition for circular bio-based cities based on a reductionist metabolic approach

The 2020 coronavirus pandemic demonstrated that moderation in living and consumption styles can contribute towards a more environmentally sustainable and resilient future. However, such restrained lifestyles are associated with the risk of global economic stagnation. Transitioning from linear to circular economy can potentially provide a framework to decouple environmental benefits from economic stasis. Circular cities are placed in the centre of such efforts to cradle and nurture humanity’s shift towards a sustainable future. However, we investigated the current state of circular cities around the world finding that a bio-based focus is not always prioritised. The lack of emphasis on bio-based solutions could lead to missed economic and environmental opportunities. A symbiosis between “circular”, “regenerative” and “bio-based” is here proposed as the foundation for sustainable societies transitioning to circularity. This Short Communication discusses the vision of circular bio-based cities and proposes a definition based on a reductionist metabolic approach. The aim is to set the basis for an international dialogue on urban development models capable of delivering both human and environmental prosperity beyond the reuse, refurbish and recycle concepts, and towards fully integrated regenerative urban systems which foster symbiotic relationships between urban communities and the natural ecosystem.

Adaptive Reuse of Heritage Buildings as Hotel in George Town UNESCO World Heritage Site: Tourism Industry Perspectives

Adaptive reuse is changing or modifying the original function to a new one. Usually, it requires some modifications to ensure that the building can meet the requirements of the new building's function. The sustainability of construction gains a lot from the adaptive reuse concept. Many heritage buildings have been adaptively reused for various purposes. However, the adaptive reuse approach to conserving heritage buildings in Malaysia needs to be practised with the right concepts and methods. To succeed in the adaptive reuse concept, various factors such as location, modification, services, promotion, and management must be done correctly. Significant losses can be avoided if the adaptive reuse of the heritage building is well-planned. Adaptive reuse of heritage buildings as a hotel is one of the catalysts in the tourism industry. This research aims to analyse the perspective of hotel guests, especially tourists internationally and locally, on the adaptive reuse of heritage buildings as a hotel in the core and buffer zones of George Town, UNESCO World Heritage City. The questionnaires were distributed to hundred twenty-two (122) respondents, which are hotel guests, to get feedback on their experiences while staying in the hotel with the adaptive reuse concept. The respondents were requested to give feedback on their experiences staying at the hotel using a 5-point Likert scale. The collected data were analysed descriptively. The result shows that the respondent was satisfied with the stayed and experiences in the hotel. Although respondents have a good experience with the stay, there is still a way for improvement. The findings also show that it is essential that the parties involved in the hotel and tourism industry follow the heritage act in adaptive reuse of heritage building practice to make sure that future generations will have the opportunity to see and appreciate heritage buildings in their current form as it was constructed hundreds of years ago.

Adaptive Reuse of Heritage Buildings for Sustainable Urban Regeneration: Two Case Studies from India

In the era of globalization, developing existing cities into smart cities while providing a higher quality of life to the citizens is one of the strategies in many countries. In the process, many traditional settlements and cultural heritage are being demolished without respecting their values. In fact, these heritage buildings could be easily re-used. However, a proper approach is essential in ensuring their relevance in urban regeneration projects. Undeniably, cultural heritage should be preserved with their values. One of the ways to do so is through adaptive re-use, i.e., reusing the existing building for contemporary use, making it a part of sustainable architecture. Appropriately, the reuse of heritage buildings or materials therein saves much of the embodied energy. This will help improve access to clean energy and encourage adoption of low-carbon energy assets. The concept of adaptive reuse of different buildings has been successfully implemented in many countries. This paper examines the issue of multifaceted challenges in adaptive reuse, emphasizing the need for informed decisions based on in-depth assessments. The paper seeks to understand the compatibility of new functions with the physical and historical integrity of heritage structures, the conservation of embodied energy inherent in these buildings, and the pivotal role of stakeholders in driving successful adaptive reuse projects. It employs a mixed-method approach using case studies, stakeholder surveys, and heritage building analyses to determine best reuse solutions. The study shows how adapting old buildings saves energy and the environment by comparing them to new buildings. It concludes revealing the current efforts to provide ways of such reuse of heritage buildings based on several sustainable benchmarks and valuable considerations.

Deep Transfer Learning with Enhanced Feature Fusion for Detection of Abnormalities in X-ray Images.

Medical image classification poses significant challenges in real-world scenarios. One major obstacle is the scarcity of labelled training data, which hampers the performance of image-classification algorithms and generalisation. Gathering sufficient labelled data is often difficult and time-consuming in the medical domain, but deep learning (DL) has shown remarkable performance, although it typically requires a large amount of labelled data to achieve optimal results. Transfer learning (TL) has played a pivotal role in reducing the time, cost, and need for a large number of labelled images. This paper presents a novel TL approach that aims to overcome the limitations and disadvantages of TL that are characteristic of an ImageNet dataset, which belongs to a different domain. Our proposed TL approach involves training DL models on numerous medical images that are similar to the target dataset. These models were then fine-tuned using a small set of annotated medical images to leverage the knowledge gained from the pre-training phase. We specifically focused on medical X-ray imaging scenarios that involve the humerus and wrist from the musculoskeletal radiographs (MURA) dataset. Both of these tasks face significant challenges regarding accurate classification. The models trained with the proposed TL were used to extract features and were subsequently fused to train several machine learning (ML) classifiers. We combined these diverse features to represent various relevant characteristics in a comprehensive way. Through extensive evaluation, our proposed TL and feature-fusion approach using ML classifiers achieved remarkable results. For the classification of the humerus, we achieved an accuracy of 87.85%, an F1-score of 87.63%, and a Cohen's Kappa coefficient of 75.69%. For wrist classification, our approach achieved an accuracy of 85.58%, an F1-score of 82.70%, and a Cohen's Kappa coefficient of 70.46%. The results demonstrated that the models trained using our proposed TL approach outperformed those trained with ImageNet TL. We employed visualisation techniques to further validate these findings, including a gradient-based class activation heat map (Grad-CAM) and locally interpretable model-independent explanations (LIME). These visualisation tools provided additional evidence to support the superior accuracy of models trained with our proposed TL approach compared to those trained with ImageNet TL. Furthermore, our proposed TL approach exhibited greater robustness in various experiments compared to ImageNet TL. Importantly, the proposed TL approach and the feature-fusion technique are not limited to specific tasks. They can be applied to various medical image applications, thus extending their utility and potential impact. To demonstrate the concept of reusability, a computed tomography (CT) case was adopted. The results obtained from the proposed method showed improvements.

Three monuments to Rhodopaios: a case study of re-use and continuity at Aphrodisias in the sixth century

The honorific monuments erected in late antiquity in the city of Aphrodisias are striking in their preservation and in their appearance. Two scholars, Charlotte Roueché and R.R.R. Smith, have provided full and ground-breaking publications of these monuments and have extracted important information from careful study of the epigraphic and sculptural elements. Further study conducted under the aegis of Smith and B. Ward-Perkins in the Last Statues of Antiquity Project, has grounded these monuments in the larger, empire-wide context of late antiquity. These fine academic studies have made these late Aphrodisian honours points of reference. Without the work of these distinguished scholars, this paper would not be possible or relevant. This paper seeks merely to focus attention on small details of structure, technique, and iconography in an attempt to sharpen our vision of the very last of these monuments. It endeavours to distinguish tendencies specific to the sixth-century honorific statuary habit at Aphrodisias and to understand the concept of re-use and recycling in that last moment of the statue culture in this conservative city, by looking at three monuments dedicated to the same man in the last moments of the habit. These are three statues monuments to one Rhodopaios of the second quarter of the sixth century, preserved in different states. The paper is divided into three parts; an introduction that considers the main trends of honorific statuary, the presentation of the three monuments of Rhodopaios, and a conclusion.

A Web Based Employees’ Cyber Security Ethical Behavior Assessment (ECEBA) Model for Ugandan Commercial Banks

Purpose: Despite the existence of Cyber Security technical controls, checklists, and formal procedures in the banks; there exists no employees’ assessment tool for Cyber Security ethical behavior. This research presents the creation of such a tool. This research aimed at enhancing Cyber Security by developing a Cyber-Security Ethical Behavior Assessment (ECEBA) model.
 Methodology: ECEBA model was used as an experimentation instrument for the development of a web-based application (ETHICA) for assessing Cyber Security ethical behavior. Unified Modelling Language (UML) was used. The ECEBA model followed the reuse concept by customizing the 3-tier architecture of the web application development. The front end interface was done using HTML5 to design the web interfaces of the ETHICA Application. To style the interfaces, CSS3 was used. Then JavaScript was used as a client side script to validate the data before submitting it to the server. AJAX a JavaScript library was used to allow submission and loading of data. Bootstrap was used to achieve responsiveness of the user interfaces. XAMPP a local MySQL server was used to host the database and the system files. Object Oriented PHP was used to act as a GUI to manage data communication between the server and interfaces. PHP Data Object driver class was used to achieve this. SQL was used to write the queries purposely to perform data processing on the server.
 Findings: The ECEBA model was developed. Deployed to the internet via URL http://Cybersecurity.groxels.com. It guided the design of ETHICA Application.
 Recommendation: Ethical behavior questions based on virtue ethical theory, Theory of Planned Behavior (TPB) and Ethical climate theory are fed into the ETHICA Application. This provides a platform for managers in assessing those individuals who may present Cyber security unethical behavior. Banks should give employees opportunity to assess themselves. Banks to use the model in conducting Employee pre-hire screening and periodic assessments of current employees. Banks should integrate the model with other cyber security controls for better ethical decision making & planning.

Preliminary study on End-of-Life Vehicles recycling rate for Malaysia

Malaysia has yet to introduce a proper laws and regulations that allow appropriate disposal of End-of-Life Vehicles (ELV). Moreover, there are lacks data captured regarding the management of ELV across different management due to unknown practices and systems. The implementation of non-environmentally ELV processed which include river dumping has raised varied issues. Recently, Ministry of International Trade and Industry (MITI) and Malaysia Automotive, Robotics and IoT Institute (MARii) has introduced several measures starting with the introduction of national automotive policy towards the importance of reuse, repair, remanufacturing and recycle (4R) concept on ELV management and development of Authorised Automotive Treatment Facility (AATF) to dismantle ELV parts. To evaluate the importance and AATF functions, a study was conducted to examine and characterise AATF process in Malaysia and evaluate the wastes generated from the practices. From the initial results, the recycling rate of ELV done in AATF has managed to achieve 90%. Moreover, it is expected that more materials and components can be recycled and recovered due to the involvement of additional ELV treatment stakeholders.

Structural efficiency evaluation of innovative reusable launch vehicles

This work is focused on evaluating the structural design of the innovative reusable micro launcher MESO, originated from the RRTB, a funded project by EU. The structural efficiency of MESO is evaluated in association with its mass budget, which is based on project’s early adopted requirements. In this particular design loop, the reusability concept is intergraded by implementing the fail-safe design approach, considering the exclusive use of high TRL aluminum alloys. The main objective of this work is achieved by developing a global Finite Element Model (FEM), comprising a set of sub-models, which represent the primary structure, the secondary structures, the equipment and their interfaces as well.The paper proceeds with the description of the modelling approach regarding mesh development and the connections created between the sub-models for assembling the integrated Global FEM of the launcher. The first iteration of the load analysis loop resulted in the extraction of the Design Limit Loads (DLL). The DLL investigated in both ground and flight cases, which comprise the most severe combination of quasi-static loads. The FEM is verified and subjected to various types of preliminary structural analysis, taking into consideration the required ECSS design and safety factors for static strength and stability assessment.The analyses results indicated the order of magnitude and the location of all weak areas of the launcher. Subsequently a preliminary sizing procedure is performed in order to prevent all failure modes according to the structural design requirements. The conclusions derived from the structural analysis of the first design loop influence the design modifications to be considered for the next design loop, where the same steps are going to be followed until the structural design requirements are satisfied once again.

The use and re-use of timber structure elements, within a waste hierarchy concept, as a tool towards circular economy for buildings

Wood is the only natural renewable building material, produced by photosynthesis. It has the ability to preserve the stored carbon in its molecular structure as long as it remains within a structure. Timber dwellings are re-gaining recognition worldwide, especially in remote areas due to their aesthetic superiority, durability and harmony with the natural landscape. Research findings, as well as industrial operations indicate that timber buildings present beneficial environmental impacts, compared to other common building materials. Specifically, timber has substantial strength characteristics, low embodied energy, less CO2 emissions and also an easy and fast construction, combined with minimum disruption to the environment. Moreover, timber buildings have a high potential to reduce waste at site and ability for re-use, when designed for future ease of deconstruction, providing the repeated utilization of the used material, known as, the cascading concept. It is already recognized that successful waste management is a measure towards the containment of climate change. Using timber structures enhances the chances to accomplish the contemporary waste hierarchy concept, which can be implemented according to the application of Design for Deconstruction and Reuse (DfDR) concept, at an early stage. These waste management techniques are strongly related to circular economy, but can only be achieved through the aim of a long-lasting design. Finally, in most countries, the existing building codes should be revised in order to overcome the imposed limitations on the re-use of building materials.

Stabilization Tank with Respect to Detention Time for Grey Water Treatment

Abstract: Characterization and treatment of grey water; options for (re)use. PhD thesis, Wageningen University, The Netherlands. Addressing the issues of water shortage and appropriate sanitation in Jordan, domestic grey water treatment receives growing interest. Grey water comprises the domestic wastewater flows excluding waters associated with the toilet. The topics of concern for grey water are its characteristics, treatment and potentials for use after treatment. The target of this thesis is to develop a concept for treating grey water on-site for agricultural usage, thus sustaining a recycling process of grey water in Jordan. A review was made regarding the currently available grey water treatment technologies. In addition, grey water was quantitatively and qualitatively characterized, and then grey water reuse requirements including treatment, were analyzed. Biodegradability and biodegradation rates of the grey water were investigated for selecting appropriate design and operation criteria of the treatment technology to be developed. A low-tech semi-technical scale treatment system was tested to treat grey water discharges from a dormitory at the Jordan University campus. The treatment system was evaluated on obtained removal efficiencies and conformity of the effluent to the guidelines for the use of reclaimed water for irrigation in Jordan. Finally, the objectives, approaches and the results of each chapter are summarized, and then both the results and the potential of applying decentralized sanitation and reuse (DeSaR) concepts in Jordan are discussed. Results show that storage and treatment are prerequisites for any type of grey water use. Grey water is aerobically and anaerobically biodegradable but the conversion rates are low. The core of the treatment concept consists of an integrated storage and anaerobic treatment unit, fed with a natural influent flow pattern, in a down-flow mode, up to a one day operational cycle, i.e. a variable HRT ≤ 24 hours. The second step consists of an aerobic post-treatment, mechanically aerated in a down-flow mode and a one day operational cycle, i.e. 24 hours HRT. Both units need insulation in the winter period. The final effluent, stable in winter and summer, meets the Jordanian

Dietary Fiber from Plant-Based Food Wastes: A Comprehensive Approach to Cereal, Fruit, and Vegetable Waste Valorization

The agri-food industry generates significant quantities of plant-based food waste from processing, which offers a valuable research opportunity aimed at minimizing and managing these wastes efficiently in support of zero waste and/or circular economies. In order to achieve food security, all of these wastes can be valorized using downstream processes in an integrated manner, which results in the conversion of waste into secondary raw materials. Specifically, plant-based food wastes and/or byproducts are recognized sources of bioactive chemicals, including dietary fibers that are beneficial as food additives or functional food ingredients that can meet the technological and functional requirements of health-promoting value-added products. Additionally, cellulosic ingredients can be utilized directly within nonfood industries, such as textiles, resulting in a reduction in the environmental impact of secondary raw materials, as well as an increase in market acceptance compared to those currently on the market. On this basis, the present review was designed to provide an overview of introducing novel concepts for effective reuse, recyclability, and maximal utilization of plant-based food wastes and/or byproducts from food-processing industries, which creates a potential opportunity for the extraction of value-added dietary fiber with potential applications in food and nonfood industries.

Mechanical and microstructural behavior of industrial spent catalyst waste and boron carbide reinforced aluminum matrix composites

The concept of reuse and recycling has undergone sustained development in industries to prevent the exhaustion of naturally available resources. The current study is about reusing spent catalyst waste from petroleum refining industries as reinforcement in aluminum composite materials. This work utilized the stir casting method to create nano B4C/waste spent catalyst/Al matrix composites by varying the B4C from 0.5 to 2.0 wt% and maintaining the constant 10 wt% of spent catalyst waste, respectively. Furthermore, the impact of nano B4C and spent catalyst waste on the mechanical and microstructure behavior of aluminum matrix hybrid composites were studied. The compressive strength, hardness, and tensile strength of the aluminum composites obtained with different percentages of nano B4C and spent catalyst waste were enhanced significantly. The increase in tensile strength mainly due to the effect of the Orowan strengthening mechanism and thermal stresses caused by the difference in the CTE of aluminum matrix and reinforcement. The effective mechanical behavior was obtained with 1.5 wt% B4C and 10 wt% spent catalyst waste with massive improvements in hardness (65.62%), compressive (31.81%), and tensile strength (48.23%), respectively, compared to base pure aluminum.

Sustainable Fashion Education: Future Design and Pedagogy

Fashion is an ever-changing phenomenon and as the world progresses in the post Covid scenario, the materials that would be used for making products would be given a more ecofriendly approach. The production processes to be adopted should be able to reduce the amount of carbon footprint on the Earth’s surface. Sustainable concepts of Recycling, Reuse and Redesign needs to be given preference in ideation of product so that we are able to put a check on the fast-depleting resources of the Earth. Research on development of more ecofriendly, biodegradable material should be undertaken. Frugal Innovation is also an area to be considered while designing products.
 As design is pervading into more avenues of communication and commutation which are the key aspect of life, so there is a need to incorporate sustainable features in these avenues also. Fashion and Lifestyle would undergo a sea change in materials and technology being used to create them.
 Therefore, the looking at the environmental concerns and the need for innovation, design curriculum of the fashion institutes needs to be relooked at. These premier design institutes of the world should focus on inclusion of sustainable design concepts, materials and production processes in their curriculum so that the design fraternity is able to contribute positively to the environment. The future professional should have multi-dimensional knowledge of “Everything and Everywhere” to meet the design challenges of “Environment and Life on Earth”. To meet these challenges of future in Design and Fashion, some Professional, Technologists and Academicians associated with design and technology would be interviewed to understand the changes in design pedagogy and strategy which needs to be adopted and incorporated to meet the sustainable design challenges in Fashion education in future.

Thermal, acoustic, and fire performance characterization of textile face mask waste for use as low-cost building insulation material

Environmental issues are becoming increasingly important, and researchers are developing new technologies and models to reduce environmental impact. The circular economy is a production and consumption model that involves sharing, borrowing, reusing, repairing, reconditioning and recycling existing materials and products for as long as possible. This study focuses on the concept of reuse and, specifically, how to reduce waste generated by pandemics through recycling and reusing facemasks made of polyamide fabric. Facemasks can be reused to refurbish buildings in low-income contexts. To assess the reutilization potential of recycled bulk polyamide fiber, thermal, acoustic, and fire performance properties were assessed experimentally. The results show that they are comparable to commercial insulation materials such as glass wool and mineral wool in terms of thermal conductivity, while also demonstrating good sound absorption performance at medium and high frequencies (greater thickness and density will increase the amount of insulation and sound absorption). The material's fire performance is similar to that of other synthetic insulation materials, such as EPS. However, the performance is worse than for common organic insulation materials, such as cellulose. Finally, a low-cost, self-portable insulation panel concept designed for indoor installation was tested for material performance. Considering these properties, this solution may represent a significant opportunity to enhance thermal and acoustic comfort in vulnerable energy-poor households, bringing clear environmental benefits and positive social implications.

Antioxidant, antibacterial, and anti-inflammatory Periplaneta americana remnant chitosan/polysaccharide composite film: In vivo wound healing application evaluation

Periplaneta americana (P. americana), which is widely used for wound healing in China, produces a large amount of solid waste (P. americana remnant) after pharmaceutical production extraction. P. americana remnant chitosan (PAC) has a low molecular weight, low crystallinity, and easily modifiable structural properties. In this study, PAC and P. americana remnant polysaccharide (PAP) were used as raw materials to prepare a composite film (PAPCF). The good biocompatibility of the composite film was verified by cell proliferation assays and protein adsorption assays. The bioactivity of the composite film was assessed by antibacterial and in vivo/vitro antioxidant assays to evaluate its potential as a wound dressing. The wound healing experiment revealed that PAPCF improved wound closure and collagen deposition, decreased reactive oxygen species levels, and attenuated the inflammatory response, enabling rapid wound healing from the inflammatory phase to the proliferative phase in mice. Additionally, PAPCF was administered only once, reducing the chance of infection from multiple deliveries. In summary, this paper presents an easy-to-administer, cost-effective, and effective dressing candidate for wound treatment based on the environmental concept of resource reuse.
