The corrosion of the steel reinforcing bar (rebar) reduces the strength capacity of concrete structures. Corrosion detection at the early stage of steel rebar implementation is important for the maintenance of concrete structures. Using the eddy current testing method, we developed a portable system to evaluate the corrosion of steel rebars. An AC current was sent to the excitation coil to produce an AC magnetic field and an eddy current was induced in the steel rebar. A detection coil was used to detect the signal produced by the eddy current. A lock-in amplifier was used to obtain the same phase signal and a 90-degree phase difference signal and an X-Y graph was plotted. From the slope of the X-Y graph, the corrosion of the steel rebar or steel wire can be evaluated. We examined the effects of excitation frequency, coil type, and coil size on the experimental results to optimize the system. The signal-to-noise ratio and the detection depth were improved with a specially designed probe. Full article

This publication examines the representation of information within test specifications and formulas defined in standards and directives. This information often pre-defines not only the tests and requirements to be conducted but also the information backflow within the execution. These results are crucial for the effective management of knowledge throughout the product development process as well as for the creation and maintenance of digital representations of a physical product or plant. However, the accessibility of this information is frequently hindered by its extensive and heterogenous definition across a multitude of standards, directives, and other technical regulations. Furthermore, the pre-defined information is typically documented and processed manually on a recurring basis. Given this challenge, the following article presents a holistic two-part approach for pre-defining the information backflow of subsequent physical instances. Initially, an analysis of multiple test specifications in standards and directives is conducted, resulting in the development of a generic data model to represent this Pre-defined Information Backflow (PdIB). The second step builds on the first and defines an optimized representation for machine readability and executability for the future design of standards and directives. The two parts are brought together and validated using representative examples, thereby demonstrating the practical applicability and effectiveness of the proposed approach. This enhances the accessibility and usability of information in test specifications and formulas, thereby establishing a foundation for enhancing the efficiency of knowledge work in product development and the creation of digital representations of products and plants.

The growing concerns about global warming and its perceived influence on economic sustainability require a reassessment of the environmental consequences of gold mining, with a special focus on BRICS countries: Brazil, Russia, India, China, and South Africa. This paper examines the environmental sustainability corridor, carbon emission, gold price, economic growth, foreign direct investment (FDI), and renewable energy use between 1989 and 2020. The long-run association among the variables is checked by us through the PMG technique. Our findings indicate that while the gold price, FDI, and renewable energy use decrease carbon emission, economic growth adds to the increase in carbon emissions in the long run. These findings bring out the dual challenge of promoting economic growth while managing environmental impact. The study underlines how policymakers need to provide regulatory frameworks which will encourage renewable energy and responsible foreign investment, as a means of trying to mitigate the environmental impacts of gold mining and achieve sustainable development. Our research adds to the continuing debate about how economic expansion can be balanced with environmental preservation for resource-rich countries. Full article

This study addresses the critical need for improved sustainability reporting in the construction sector, focusing on the integration of Life Cycle Sustainability Assessment (LCSA) indicators to enhance reporting quality and promote standardization. The increasing regulatory pressure from the European Commission, particularly in sustainability reporting, has intensified the demand for corporate transparency. Despite these efforts, many companies still face challenges in implementing robust sustainability performance measures. This research employs a systematic literature review alongside the case studies of three leading German construction companies to critically assess the current reporting practices and explore the integration potential of LCSA indicators. The findings highlight a significant gap between the existing sustainability disclosures and LCSA indicators, with only 7–19% of the assessed indicators being integrated into the current reporting practices. Although some consistency in reporting themes and qualitative disclosures is evident, the misalignment with LCSA indicators underscores the need for further integration of standardized, life cycle-based metrics. This study concludes that collaborative efforts among companies, policymakers, and LCSA researchers are required to bridge this gap, ensuring the adoption of the existing, scientifically robust indicators that enhance the precision, comparability, and transparency of sustainability reporting in the construction sector.

According to conclusions agreed to in the 1995 Report of the World Summit for Social Development and the 2015 Sustainable Development Summit, seventeen sustainable development goals (SDGs) have been ratified and published as the 2030 Agenda for Sustainable Development. In 2022, the 8th Environment Action Programme was legally agreed upon, following the six European Green Deal priorities. These SDGs serve as a constant reminder of the importance of globally coordinated actions in compliance with the theory of sustainable development. However, more than a constant reminder, this international agreement should become the foundation for necessary change. On 22 July 2024, the daily global average temperature reached a new record high. The EU treaties signed between 1951 and 2007 laid the foundation for the creation of EU environmental policy. However, those EU treaties, along with environmental policy, form merely a non-binding and minimum set of priorities without any sanctions imposed for illegal practices. In 2021, EU member countries adopted the European Climate Law as the first legally binding document seeking to achieve goals set by the Paris Agreement and the European Green Deal. Any further EU sustainable development policies are dependent on global cooperation as a key element of survival. With the EU’s dependent on the rest of the world for its energy, the forcing of any obligatory change will be hard to achieve. This proves the importance of the 17th SDG, agreed in 2015. Only global partnership for sustainable development can prevent further damage to our ecosystem and achieve priorities set by the EU and UN agendas. The review aims to present the connection between sustainable development (SD) goals defined by the European Commission, for which the most important aspects are the need to meet the environmental requirements to protect future needs in the long run, and to confront the shortcomings of European law-making practices, in which most crucial reforms are presented as non-binding legal acts. Finally, in 2024 members of the European Parliament established an extended list of environmental crimes to be regarded as punishable offences and replaced the Environmental Crime Directive, making criminal activities and offences potentially legally punishable; however, it is yet to be seen how this initiative will be incorporated within the national legislations of each EU member country and to what extent.

The purpose of the qualitative multiple case study was to explore the strategies some supply chain managers of the United Nations (UN) use to leverage operational efficiencies in the UN humanitarian programs. As a result, communities supporting sustainability and peace or those fostering economic development will be able to respond effectively to humanitarian crises. Moreover, the UN can remain operational and engage in political and conflict-reduction interventions integral to economic and social recovery and sustainability. This study applied the qualitative multiple case study through semi-structured interviews with nine supply chain managers in the United Nations, direct observations, document analysis, and artifacts. The research is grounded in the dynamic capability theory (DCT). The research revealed several strategies that supply chain managers of the UN use to ensure operational efficiencies grouped around three themes: (a) analytical, innovation, and knowledge management strategies; (b) effective supply chain management leadership strategies; and (c) risk management strategies. This study is one of the first to apply generic findings of humanitarian supply chain studies to the United Nations, the global organization with diverse mandates that continuously strives to achieve efficiencies required by donors providing financial support, thus remaining operational. The study’s results could help leaders in the various humanitarian organizations who operate in vulnerable environments and under strict scrutiny from donors to deliver their aid programs most efficiently by understanding dynamic capabilities. Previous studies indicate the lack of strategic frameworks applicable to the United Nations that could improve decision-making at the strategic, tactical, and operational levels, facilitate collaboration among supply chain stakeholders, and reduce the costs of the operational performance of the supply chain system in the UN.
