A Systematic Literature Review on Energy Efficiency Analysis of Building Energy Management

Government agencies, energy consumers, and other societal groups have all shown concern and attention for the energy management of buildings. Relevant statistical data, however, indicate that most public buildings continue to consume large amounts of energy overall and that the issues of low energy usage and energy waste have not materially improved. As a result, this study reviewed the state of progress and potential directions for future research in the field of building energy management in public buildings using a data-driven approach. Relevant studies were obtained from three databases—Web of Science, Scopus, and China National Knowledge Infrastructure—based on certain search phrases. The text mining program VOS viewer was then used to examine the material. We provide a thorough examination of the study techniques and material, as well as a visual representation of the keywords and current state of the field. According to this study, the range of data processing outcomes; the flexibility of research system standards; and the availability of a comprehensive, unified assessment system are the main factors contributing to the practical issues facing building energy management today. Based on the geographic distribution and state of energy development, this study is the first to examine possible research avenues for building energy management in public buildings through cross-fusion research on passive energy-saving design and subjective behavioral energy-saving. It offers a foundation for developing the building energy management system best practice model in the future.

The Catalytic Effect of Low Molecular Weight Acids on the Physicochemical and Dielectric Properties of Oil-Paper Insulation Systems.

In most industrialized countries, power transformers built several decades ago are approaching the end of their operational lifespan. The ongoing energy transition, focused on developing 100% renewable energy sources and accelerating global transportation electrification, further exacerbates these assets. Combined with rising electricity demand, there is an increasing risk of critical transformers' degradation acceleration. In this context, understanding the aging mechanisms of the insulation system inside these essential assets, which form the core of every energy network, becomes paramount for today's managers and engineers responsible for their operations. The acids generated through oil oxidation can be classified into two categories: low molecular weight acids (LMAs), which are inherently more hydrophilic and consequently have a greater impact on the degradation rate of solid insulation through hydrolysis, and high molecular weight acids (HMAs), which do not significantly contribute to the degradation of paper insulation. This study specifically addresses the impact of acids generated through oil oxidation-focusing on LMAs. New oil samples were infused with different ratios of LMAs before impregnation. The impregnated paper samples underwent thermal aging at 115 °C. Different physicochemical and dielectric properties were investigated. The investigations revealed that oils blended with formic acid exhibited more adverse effects on the insulation system compared to other LMAs. This information is essential for industry professionals seeking to mitigate the risks associated with transformer degradation and extend the lifespan of these critical assets during the energy transition.

Application of 5G network technology in agricultural production and information management

Establishing a management information system that adapts to the continuous development of agricultural production management today, adopting advanced 5G technology and means, and comprehensively managing the entire agricultural production is an inevitable trend in the development of agricultural production management. In order to improve the effect of agricultural production informatization management, this paper combines 5G (fifth-generation) network technology to construct agricultural production and informatization management models. In view of the massive dynamic agricultural production management data, this paper studies the efficient multi-copy management strategy, which can consider the two aspects of load balancing and energy efficiency at the same time, so as to achieve efficient data access and energy efficiency. Moreover, this paper introduces a time series-based file access heat calculation model. In terms of determining the number of copies of files, this paper proposes a copy factor allocation algorithm centered on the ranking of file access popularity, and gives a characteristic function. Through cluster analysis, it can be seen that the agricultural production informatization management model based on 5G technology proposed in this paper can effectively improve the efficiency of agricultural information management.

Women leaders in logistics for the economy 5.0

The complexity of the technologized socioeconomic reality poses a number of challenges for today's managers. Many times their actions are a test of their leadership. A particularly interesting area of research in this regard is the logistics sector, which so far has been regarded as typically male and which has been undergoing a transformation in favor of an increasing representation of women for some years now. The authors sought to answer questions such as: what qualities, skills and competences will enable women working in logistics to pursue their careers and achieve their goals in the face of the challenges of a 5.0 economy. The aim of the article is to identify those leadership skills and competences of women in logistics that predispose them to lead on their way to business success in enterprises. In the research process, mixed research methodologies were used, combining the results of secondary source analysis obtained from Scopus and Web of Science databases with information obtained from a quantitative survey based on the CAWI diagnostic survey method. The analyses resulted in a model of an exemplary image combining traits, skills and competencies, as well as attributes of effectiveness, which may be helpful for women in shaping their leadership position in the management structures of companies in the logistics industry. The resulting material complements the existing body of research on the role and importance of women in business including, in particular, the inclusion of women in logistics. The main strength of the work is to identify areas that women should improve in order to increase their participation in managerial positions in the logistics industry.

Concerning emotions: feminist contributions to reflexive marine governance

ABSTRACT This paper is concerned with emotions in marine governance. Governance studies are currently undergoing a ‘reflexive turn’ that focuses on the ‘how’ and ‘who’ of processes and practices of governing. It is also important to ask ‘why’ modes of governing emerge as they do. Drawing on feminist theories, this paper explores the ways that societal constructions of emotions, as well as the subjectivity of emotions, suffuse decision-making. Drawing in depth on the concerns driving the development of the United Nations Convention on the Law of the Sea (1986), and the roles of Arvid Pardo and Elisabeth Mann Borgese in its development, this paper shows how a global-level governance outcome was simultaneously a deeply embodied one, where emotional work, structured by socialised norms, identities, values and opinions, shaped governance. It addresses why this governance tool emerged in a specific form, and how the factors shaping it persist in ocean management today. To conclude, the paper hints towards other examples that might benefit from the reflexive approach developed while also contending that recognising the role of emotions is a useful addition to studies of marine governance, leading to more care-full, reflexive, and resilient forms of governance in the face of uncertainty.

Challenges for Customs Risk Management Today: A Literature Review

Changes and uncertainty in the customs operating environment and the growth of trade and travel volumes have affected how customs administrations manage and approach their tasks. As a result of technological development, the role of customs in border control has changed dramatically. Thus, the massive volume of goods, the way they are traded worldwide, and the speed of such transactions create additional fiscal, security, financial, and safety risks, affecting the resources available to customs services. The current geopolitical situation has significantly impacted the role of customs services. The topic is relevant to simultaneously assure both the quality of the services provided by the customs and compliance with the requirements set in the framework of limited resources. This study focuses on customs risk management (CRM) issues. It acknowledges that the customs services must continuously improve their operational methods, including promoting a more structured, integrated, and systematic way to manage customs risks. Based on the literature review, we examine the CRM-related challenges and how scholars address them in the scientific literature. This study aims to identify and analyse the contemporary challenges in CRM from its effectiveness point of view. We employ a systematic literature review, searching in most recognised databases and covering the period of 2005–2024. We follow this with a qualitative content analysis and synthesis, summarising and discussing the study results. We identify and discuss relevant key factors contributing to effective CRM. Finally, we conclude with the implications of the findings for CRM practice and policy, as well as with various potential developments in CRM that we suggest for further work.

Labor patterns of spontaneous first-stage labor in Chinese women with normal neonatal outcomes.

Friedman's standards, developed almost 50 years ago, may no longer align with the needs of today's obstetric population and current pregnancy management practices. This study aims to analyze contemporary labor patterns and estimate labor duration in China, focusing on first-stage labor data from Chinese parturients with a spontaneous onset of labor. This retrospective observational study utilized data from electronic medical records of a tertiary hospital in Changsha, Hunan. Out of a total of 2,689 parturients, exclusions were made for multiple gestations, preterm, post-term, or stillbirth, cesarean delivery, non-vertex presentation, and neonatal intensive care unit admission. Average labor curves were constructed by parity using repeated-measure analysis, and labor duration was estimated through interval-censored regression, stratified by cervical dilation at admission. We performed an analysis to assess the impact of oxytocin augmentation and amniotomy on labor progression and conducted a sensitivity analysis using women with complicated outcomes. Nulliparous women take over 180 minutes for cervical dilation from 3 to 4 cm, and the duration from 5 to 6 cm exceeds 145 minutes. Multiparous women experience shorter labor durations than nulliparous. Labor acceleration is observed after 5 cm in nulliparous, but no distinct inflection point is evident in the average labor curve. In the second stage of labor, the 95th percentile for nulliparous, with and without epidural analgesia, is 142 minutes and 127 minutes, respectively. These findings provide valuable insights for the reassessment of labor and delivery processes in contemporary obstetric populations, including current Chinese obstetric practice.

Performance modification of an acid gas incinerator to reduce atmospheric pollutants impact: Energy management, HAZOP and LCA analyses

In today's industrial landscape, energy management, process modification, and reduction of atmospheric concentrations of pollutants and safety risks have become paramount. This focus is driven by the need to address environmental concerns, economic efficiency, and the global energy and climate change crisis. In gas refineries, incinerators are widely used to convert deadly and environmentally polluting acid gases into less hazardous gases. Therefore, improving incinerator performance can significantly impact environmental, economic, and energy aspects. According to the results of an energy management study at the domestic gas processing plant, the acid gas incineration unit was identified as a significant energy use. Therefore, based on the effects of the performance of this incinerator from environmental and energy points of view, the mentioned unit was prioritized for modification in this work. For this purpose, incinerator performance was assessed using Promax simulation, and Hazard and Operability (HAZOP) analysis was employed to identify potential hazards. The simulations revealed that acid gas residence time was 0.81s, longer than the 0.6s initial design with the damper in place. This suggests damper removal is feasible. Removing the damper reduces residence time and lowers incinerator temperature, especially during startup. Therefore, temperature was considered as the keyword in the HAZOP study, and a number of recommendations were proposed to eliminate or mitigate the risks of system modification. Furthermore, the assistance of results obtained from energy management based on ISO 50001:2018 standards confirm improvements in energy efficiency and fuel consumption, which have positive economic and environmental impacts. Moreover, the study employs a Life Cycle Assessment (LCA) approach using SimaPro Software 9.5.0.1 and the CML-baseline method (Centrum voor Milieukunde Leiden) for environmental impact assessment. The results reveal that, across ten environmental impact categories, the modified project exhibits significantly reduced environmental impacts compared to its original state.

PSYCHOLOGICAL AND PEDAGOGICAL ASPECTS OF LEARNER KNOWLEDGEMANAGEMENT

The relevance of this study is determined by the fact that atthe present stage knowledge becomes the most valuable resource for the development of the economy and society. That is why the system of higher education, which lays the foundations of knowledge development management, should be based on modern developments of researchers on the issue of ensuring the effectiveness of knowledge management. However, there is a problem in this issue, in particular, what research should be emphasised when developing the conceptual framework of knowledge development management of university students. This is due to the fact that for the first time the scientific justification of knowledge management was carried out on the basis of the results of practical developments in the conditions of enterprise work (in particular, the issues of personnel motivation were formulated in the works of American authors as knowledge management tasks).The aim of the study is to substantiate the psychological and pedagogical foundations that ensure the effectiveness of knowledge management of students in higher education, formulating the competence base of the teacher that meets the challenges of innovative development. The research methods were: analysing the works of researchers on the issue of ensuring the effectiveness of knowledge management; formulating our own conclusions based on the analysis of researchers' works. We believe that the concept of knowledge management today is the main task that requires implementation and provision on the issues of development of methodology of university development strategies, in personnel and didactic issues of training teachers of universities of a new formation. Conclusions are drawn about the need to ensure effective knowledge management, which, according to the authors, requires the development of psychological and pedagogical skills of the teacher. The model of psychological and pedagogical competence of a teacher is proposed.

Criminal Sanctions For B3 Waste Management in Hospitals or Health Facilities

As a health service facility, the hospital is a gathering place for sick and healthy people, can be a place for disease transmission and allows environmental pollution and health problems. Today's management of the hospital environment is no longer a consumptive partial part but is a series of cycles and management strategies for homes. Hospitals need to develop hospital environmental management capacity to provide direct and indirect benefits to improve the quality of hospital services. Hospital environmental management has complex problems. One of them is the problem of hospital waste, which is very sensitive to government regulations. Hospitals, as one of the largest waste generators, have the potential to cause pollution to the surrounding environment, which will harm the community and even the hospital itself.

Abandoning conversion from even-aged to uneven-aged forest stands – the effects on production and economic returns

ABSTRACT There is growing interest in continuous cover forestry in Sweden. The historical domination of even-aged forest management means there is a need to focus on methods for transforming even-aged to uneven-aged stands. Practical conversion management today is highly adaptive, and the possibility of failures, such as persistent lack of tree recruitment, must be allowed for. We used simulations to evaluate various scenarios in which conversion management is introduced at different development stages in even-aged stands and then abandoned in favour of clear-felling. A shift towards an inverse J-shaped diameter distribution at the end of the simulations was most evident in northern Sweden and with an early introduction of conversion forestry. The largest losses were incurred in a scenario where the conversion management started with removing larger trees at pre-commercial thinning: it reduced the volume of production by up to 25% and, if clear-felled, resulted in a lower land expectation value than conventional management. Earlier decision to abandon conversion management reduced the losses, but the effect of timing was minor. In summary, the results indicate that conversion management could be started and abandoned without any major economic loss during the timeframe of a normal rotation.

Consideration of Sustainability in Projects: A Cross-Sectional Quantitative Analysis

The consideration of sustainability in projects is one of the most critical global trends in project management today, as projects are instrumental in the sustainable development of organisations and society. In the growing literature on this topic, most studies take a qualitative approach, often based on single case studies, and quantitative studies are underrepresented. To address these limitations, this study aims to examine the extent to which different aspects and perspectives of sustainability are integrated into projects by reporting a quantitative analysis of the consideration of sustainability in 134 projects. The analysis used the Sustainable Project Management Maturity Model SPM3 to analyse the level at which sustainability was considered in the projects. The results show that, on average, sustainability is considered at a reactive level, with the desired levels of consideration on average one level higher (proactive). When considering the different triple bottom line perspectives, the economic perspective scores highest, followed by the social and environmental perspectives. The study also shows that building-related projects score higher on sustainability considerations than other project types, as do larger projects. Limitations of the study include its European focus, the relatively small sample size, and the fact that the data was collected in different locations over a four-year period, which raises the possibility of subjective differences in the evaluation of individual projects. Nevertheless, the study can be seen as a ‘wake-up call’ for project practitioners, who need to be more proactive in this regard if projects are to be the route to sustainability.

Artificial Neural Network based FACTS in a Contingency Situation

The two biggest issues facing today's energy management systems are the ongoing monitoring of online voltage stability and the improved loadability of the transmission lines for the current electrical power system. As a result, it is highly difficult and time-consuming to assess online voltage stability under diverse loading conditions. This study describes a practical voltage stability monitoring system that automates online voltage monitoring and alerts the operator before voltage drops by computing line voltage stability indices using an ANN. This study compares evaluations of system voltage stability and loadability at the load with FACTS devices. The results suggest increase in system loadability while ensuring the security of power system operation.

Evaluation and prioritization of barriers to the implementation of the eco-regenerative supply chains using fuzzy ZE-numbers framework in group decision-making

<p>In today's supply chain management, there is a growing emphasis on transitioning to environmentally sustainable practices. This paper aimed to identify and rank the barriers to the implementation of eco-regenerative supply chains. A novel integrated approach was proposed based on stepwise weighted assessment ratio analysis (SWARA) and the multi-attributive border approximation area (MABAC) method using ZE-fuzzy numbers. This approach aimed to address some of the limitations of the failure mode and effects analysis (FMEA) method, including lack of thorough prioritization and inability to make decisions about the importance of various failure factors in an uncertain environment. By combining fuzzy sets and considering the reliability levels of two distinct groups of decision-makers and experts, this proposed method offers a comprehensive evaluation framework. Following the determination of the risk priority number (RPN) by the FMEA method, risk factors were evaluated using ZE-SWARA, and barriers were ranked using the ZE-MABAC method to identify critical barriers and propose corrective actions. Furthermore, sensitivity analysis was conducted in this study to demonstrate the viability of the proposed method. This research contributes to the advancement of eco-regenerative supply chain management practices by offering a systematic and innovative approach to addressing environmental concerns and improving decision-making processes in uncertain environments.</p>
