Against a backdrop of globalization, dynamic shifts in consumer demand, and climate change impact, the intricacies of agri-food supply chains have become increasingly convoluted, necessitating innovative measures to guarantee agri-food security and authenticity. Blockchain technology emerges as a promising solution, offering transparency, immutability, traceability, and efficiency in the overall supply chain. This study aims to investigate determinants impacting both the intention to use and the actual usage of blockchain-driven agri-food supply chain platforms. To achieve this, an expanded and adapted conceptual model rooted in the Unified Theory of Acceptance and Use of Technology (UTAUT) was formulated and empirically examined through Partial Least Squares Structural Equation Modeling using data from 175 respondents from agri-food companies across eight European countries. Agri-Food Supply Chain Partner Preparedness (FSCPP) emerged as the pivotal factor with the highest degree of influence on the intention to use blockchain-driven supply chain platforms. Additionally, the results from this study offer support for the significant influence of Performance Expectancy (PE), Effort Expectancy (EE), and Perceived Trust (PT) on usage intention, while also revealing the positive impact of Organizational Blockchain Readiness (OBR) on expected Usage Behavior (UB). This study provides significant insights into blockchain adoption within agri-food supply chains, contributing to the existing literature through an extended UTAUT framework.

The process of regeneration of abandoned areas or deteriorated structures in the cities of Romania has become a strategy of urban-integrated development. Conversions and/or regeneration of facilities in the form of assets, with different destinations, are part of the new trend of urban regeneration and a strategy used to attract investment capital. The disappearance of mining industry sites in Maramures County, Romania, has allowed the expansion and planning of new spaces for public use and/or semipublic, and most cities have opened new development perspectives. The study is based on empirical research conducted on the brownfields of Baia-Mare City. This research investigates how stakeholders of an urban regeneration project can be more actively involved in the decision-making processes with regard to the strategic elements of the renewal project of Cuprom, as a former mining industry area. This research contributes to the development of the investigation of new types of knowledge of stakeholder analysis and improves the available practices for stakeholder salience. Social networks created and consolidated by stakeholders of an urban regeneration project are the object of analysis, evaluation, and monitoring of the equilibrium between project management and grant of resources and capital. This paper studies the salience of stakeholders of the SEPA-CUPROM project from Baia-Mare using the social networking approach. Visualization by graphical methods of social networking analysis is a useful instrument in the decision-making process of brownfield projects as part of sustainable strategies in Romania.

Throughout their lifetimes, bridges are exposed to various forces that may lead to displacement and deformation, potentially compromising their structural integrity. Monitoring their structural integrity under environmental factors is essential for safety and maintenance under these conditions. This aspect is a fundamental component of Structural Health Monitoring (SHM). Many studies focus on Structural Health Monitoring (SHM), employing various theories, methodologies, and technologies that have advanced rapidly due to the expansion of information technology. The objective of this study is to pinpoint areas where research is lacking in the existing literature on the environmental factors that impact the displacement of bridges, along with the techniques and technology used to monitor these structures. To achieve this objective, the most critical environmental factors and technologies, particularly those that are sensor-based, have been identified through a systematic search of the most popular databases. Subsequently, the study utilized a bibliometric analysis, exploring the challenge and prospective research areas reflected in the specialized literature. The findings indicate a lack of scholarly investigation of environmental factors that influence the Structural Health Monitoring (SHM) of bridges, in particular studies regarding the effect of uneven sunlight on structures. The research provides a comprehensive understanding of the Structural Health Monitoring (SHM) of bridges and has practical implications for developing effective monitoring methodologies.

This paper represents a research response to the current vision on transformations regarding the capacity building of smart cities focused towards sustainability, by addressing the knowledge based urban development and collaborative tools that support the development, dissemination, and use of knowledge. The purpose of this paper is to develop a collaborative pattern of knowledge networking, focusing on sustainability goals within a smart city concept, using the logic of the Complex Adaptive System (CAS). The study was carried out in an innovation cluster in Romania; the Social Network Analysis (SNA) was used as a tool to perform the study. The results of this analysis, due to the suggested networking, have led to delimitation of the roles that Groups of Competences play to enhance the sustainability of smart cities in areas where the use of knowledge has the greatest impact. Results show that the success of the smart solutions’ implementation depends on how the social and competence structures of the network are shaped and whether it permanently adapts to fit the sustainability objectives in the considered areas.

We argue that a new type of adaptive change management is needed in Romania, in which social and territorial cohesion are key elements of governance, in accordance with sustainable development requirements. Based on critical analysis and comparative study, the paper investigates, using several approaches, the possibility to select those elements that enable determining a viable managerial sustainable development “model” for communities in Maramures County, Romania. New trends worldwide, and the multidimensional aspects of sustainable development of communities, were the subject of examination, through a regional polycentric approach, which led to a new model proposed by the authors. The result is a conceptual integrated model which promotes a balance of interaction between systems—economic, human, environmental and technological—in a dynamic, flexible and functional process.

The system of remote monitoring of atmosphere is designed to obtain information about the state of atmosphere. The principle of the remote monitoring of atmosphere is based on registering and processing GLONASS/GPS radio signals. Modern networks of active reference stations allow us to solve both practical problems of geodesy, navigation, and purely scientific problems that are important in all geosciences. The paper investigates a spatiotemporal instability in the atmosphere, based on 845 temporal measurements of tropospheric delay over the territory covered by 20 active reference stations of the UA-EUPOS/ZAKPOS network. The method elaborated by the authors for the determination of tropospheric delay in the UA-EUPOS/ZAKPOS network in real time takes relief of the region into account. The results are very good, since mapping tropospheric delay can be made with an average RMSE of 1.5 mm. The method developed in this research can be used to improve the quality of weather forecasts and the prevention of natural disasters.
