Authors: Kukharets Valentyna , Hutsol Taras , Kukharets Savelii , Glowacki Szymon , Nurek Tomasz , Sorokin Dmytro
Published: August 2023

The level of renewable energy use and economic development of a country, as separate indicators, have an influence on the level of energy resource imports, but the mutual impact of renewable energy sources and gross national product on the growth or decrease of energy imports dependency have not been studied. Therefore, the aim of this study was to evaluate the energy security of European countries by taking into account the consumption of renewable energy sources and the economic development of the countries. In particular, the article examines the relationship between energy import dependency, gross domestic product (per capita), and renewable energy sources in 27 countries in the European Union. Regression analysis of data on EU countries for 11 years (from 2011 to 2021) was used to determine the non-linear influence of gross domestic product and renewable energy use on energy import dependency. This influence was simulated by a second-order regression equation. The analysis of the equation for extremes made it possible to conclude that with a share of energy from renewable sources at the level of 32%, the economic development of a country does not require an increase in energy import dependency, and with larger values of energy from renewable sources, a decrease in energy import dependency may occur. In addition, according to the analysis of the obtained mathematical dependence, it is recommended that countries with a gross domestic product of up to 10,000 euros per capita use renewable energy sources at the level of 40%. For the countries with a domestic product of up to 30,000 euros per capita should use renewable sources at the level of 50%. For countries with a gross domestic product of more than 30,000 euros per capita, renewable energy sources at a level of more than 55% is recommended. A high level of renewable energy use will allow a country to increase its gross domestic product without a significant increase in energy import dependency, and at the level of renewable energy sources of more than 32%, an increase in gross domestic product does not actually lead to an increase in energy import dependency. An increase in the use of renewable energy sources above 40% of the total consumption of energy resources in a specific country, in particular, and in the European Union, in general, will ensure an increase in energy security and an increase in the level of energy independence.

Published: August 2023

The oxygen blast furnace with top gas recycling (TGR-OBF) ironmaking technology can reduce CO2 emissions, especially when combined with carbon capture and storage technology (CCS). However, the successful commercialization of technology cannot be achieved without economic evaluation. This study applied the Box–Behnken design method and a Monte Carlo simulation-based risk analysis to assess the sensitivity of influencing factors affecting the net present value (NPV) of an integrated steel plant (ISP) and to predict the impact of variable market scenarios on the NPV of three ISPs. The results indicated that among the three ISPs, the conventional ISP (C-ISP) is the least profitable, followed by the ISP equipped with TGR-OBF and CCS (ISP-OBF-CCS), and the most profitable is the ISP equipped with TGR-OBF (ISP-OBF), which is at least CNY 0.392 Bn and CNY 1.934 Bn more profitable than the ISP-OBF-CCS and C-ISP respectively. Under the current Chinese carbon trading policy and the cost of CCS, CCS technology does not make a company profitable. This study explored an approach for analyzing ISP economic applicability under uncertain markets, which can be used as a reference for the development of alternative processes for steel production.
A Study of Young People’s Intention to Use Shared Autonomous Vehicles: A Quantitative Analysis Model Based on the Extended TPB-TAM
Authors: Liao Yang , Guo Hanying , Liu Xinju
Published: August 2023

Shared autonomous vehicles (SAVs) have the advantages of both autonomous driving technology and shared transportation, which is an important development direction for intelligent and green transportation in the future. However, a lack of trust and a high perceived risk have reduced the public’s willingness to use this mode of travel. To improve the public’s willingness to use it, many scholars have conducted research, but young people are still a neglected group. A structural equation model was used to test the models based on 316 survey samples. The results indicated that initial trust had a significant positive effect on the intention to use SAVs, while perceived security risk and perceived privacy risk had no significant effect on the intention to use, but perceived security risk can indirectly negatively affect the intention to use. In addition, attitude and face consciousness had a significant positive influence on intention to use, while subjective norms, perceived behavioral control, and perceived usefulness had a significant indirect positive influence on intention to use SAVs. The findings showed that the model used in this paper was reasonable and valid for explaining young people’s willingness to use SAVs. This will provide guidance for formulating more effective strategies for this group.
Current Advances in Green Governance and CO2 Emissions towards Sustainable Development
Authors: Choi Yongrok , Lee Hyoungsuk
Published: August 2023

Energy and environmental studies (E&E) have faced a significant turning point due to the lack of reliability of the existing models, as well as the lack of policy governance. Most papers in E&E have adapted data envelope analysis due to its popularity, which is a result of its structure of having multiple inputs and outputs. However, due to its crucial weakness in statistical reliability, diverse new methodologies to gain better reliability have been developed, such as difference-in-difference and computational general equilibrium models, but they are still do not popular because the world has not shown significant progress in the abatement of carbon emissions. This comes not only from the lack of appropriate, precise research models, but also from a worldwide lack of governance. Most countries advocate for the necessity of E&E policies, yet their policies alone are not enough for sustainable performance, due to the lack of reliability and/or weakness of public–private partnerships. This Special Issue shall examine all of these new challenges to the methodologies, as well as the implications and suggestions arising from their empirical results.

Authors: Zhao Dandan , Jia Wenyue , Liu Jiping
Published: August 2023

The objective of this study is to analyze the spatiotemporal dynamics of net primary production (NPP) change combined with land use and to further explore the driving factors of NPP change, allowing us to provide a scientific reference point for optimizing the land-use structure and improving regional carbon sequestration capacity. The average annual NPP ranged from 200 to 300 gC/m2•a in the period of 2001–2020 in our study area. We used trend analysis and linear regression analysis to explore the spatial and temporal dynamic changes in annual NPP and analyzed the driving mechanism in a semiarid region (western Jilin Province) of China in the period of 2001–2020. The results showed that NPP presented a trend of fluctuating growth, and the spatial distribution of NPP showed that NPP values of cultivated land, forest and grassland were generally higher than those of other land-use types. The high value in the southeastern region and low value in the northwestern region were identified because there were large areas of cultivated land distributed in the southeastern part of the study area in the period of 2001–2020. The main driving factors that affected NPP were annual precipitation, CO2 emissions, GDP and hours of sunshine. NPP was positively correlated with annual precipitation, CO2 emissions and GDP, and it had a significant negative correlation with hours of sunshine. Our study provides important support for research into land-use structure and improvements to the regional carbon sequestration capacity, making an important contribution to regional sustainable development.

Authors: Thangavel Packiaraj , Chandra Bibhas
Published: August 2023

The aim of this study is to consolidate the state of mobile commerce consumer research from 2001 to 2022. Based on a systematic literature review employing a bibliometric technique, this study not only reports the significant contributions of authors and their affiliations but also discusses the evolution of m-commerce research over the last two decades. Examination of annual production trends revealed that publications were on the rise all along; the year 2022 clocked the highest number of publications (53 documents), which further reinforces that the research on this domain is in its blooming season. China is the most contributing country in terms of the number of publications and citations received, followed by the USA. The author Keng-Boon Ooi has been the most productive researcher; his studies continue to be the foundation on which m-commerce consumer research continues to thrive. The analysis of scientific mapping revealed that, although many studies were carried out on mobile commerce adoption intention, the focus of the researchers lately shifted towards studying continuous use intention (since 2018). Further, it was observed that the base theory, the Technology Acceptance Model, which has been widely used for determining antecedents of technology adoption intention, is losing its significance and is being overtly replaced by the Unified Theory of Acceptance and Use of Technology. While the topics “trust, loyalty, satisfaction, mobile banking, UTAUT, continuance intention, perceived enjoyment, and COVID-19” were identified as mother (engine) themes, the keywords “privacy, self-efficacy, social influence, TAM, attitude, and intention to use” became diminishing themes. The following topics have been identified as emerging themes: “Mobile social commerce, Mobile payment, Mobile marketing, Omnichannel, Fintech, and Live streaming commerce”. This study provides useful insights to potential researchers.
Unit Combination Scheduling Method Considering System Frequency Dynamic Constraints under High Wind Power Share
Authors: Li Qun , Li Qiang , Wang Chenggen
Published: August 2023

Power systems with a high wind power share are characterized by low rotational inertia and weak frequency regulation, which can easily lead to frequency safety problems. Providing virtual inertia for large-scale wind turbines to participate in frequency regulation is a solution, but virtual inertia is related to wind power output prediction. Due to wind power prediction errors, the system inertia is reduced and there is even a risk of instability. In this regard, this article proposes a unit commitment model that takes into account the constraints of sharp changes in frequency caused by wind power prediction errors. First, the expressions of the equivalent inertia, adjustment coefficient, and other frequency influence parameters of the frequency aggregation model for a high proportion wind power system are derived, revealing the mechanism of the influence of wind power prediction power and synchronous machine start stop status on the frequency modulation characteristics of the system. Second, the time domain expression of the system frequency after the disturbance is calculated by the segment linearization method, and the linear expressions of “frequency drop speed and frequency nadir” constraints are derived to meet the demand of frequency regulation in each stage of the system. Finally, a two-stage robust optimization model based on a wind power fuzzy set is constructed by combining the effects of wind power errors on power fluctuation and frequency regulation capability. The proposed model is solved through affine decision rules to reduce its complexity. The simulation results show that the proposed model and method can effectively improve the frequency response characteristics and increase the operational reliability of high-share wind power systems.

Our work is one of the rare studies that sought to verify the relationship between green supply chain management practices and environmental performance in companies in an emerging Latin American market. We surveyed in the specialized literature on environmental management and green supply chain management (GSCM) for practices were most cited and can influence this relationship. From this review, an e-survey was constructed and answered by 79 environmental or supply chain/logistics managers from the surveyed sample. The results indicate that there is a positive and significant relationship between the adoption of green supply chain management practices and the environmental performance of the companies. We found that GSCM practices: environmental management with total quality (GSCM4), cooperation with suppliers to achieve environmental management objectives (GSCM7), and cross-functional cooperation for environmental improvements (GSCM3), in this order. These are the main GSCM practices that influence the environmental performance in the surveyed companies. Thus, our study adds relevant information to the specialized literature and for the decision-making of managers, professionals, and government working in this area of study.

Electricity consumption during oil production is a significant cost for industry enterprises. One of state policy’s most important tasks in extracting minerals is increasing energy efficiency and the intellectualization of control and management systems. The solution to these tasks can be achieved through competent planning of the technological process and the organization of information support at all stages. The paper presents the development of a method for power consumption, the optimization of an electric submersible pump installation. The technological restrictions are also identified. The developed methodology was tested; according to the results of the calculations, it was found that the reduction in specific power consumption can reach 12.68%. An assessment of the economic feasibility of the changing parameters of the electrical equipment has been carried out. Within the framework of the integrated logistic support approach, a program was developed for the selection of rational parameters of equipment in order to increase the energy efficiency of the installation of electric submersible pumps. The research results can be applied to oil-extracting industry enterprises in the framework of energy efficiency improvement programs.
Grid Harmonics Suppression for Three Phase Dual-Frequency Grid-Connected Inverter Based on Feedforward Compensation
Authors: Chen Zhigang , Ma Dongkai , Yang Liyong , Liu Shuo , Tong Chaonan , Zhao Yifan
Published: August 2023

Using a low pulse ratio, the electromagnetic interference and switching loss of an inverter can be effectively reduced, particularly in high-power applications. However, due to variations in grid impedance, it is a challenging task to achieve stable operation of an LCL-type grid-connected inverter (GCI) using the active damping method with low pulse ratio. Thus, a novel three-phase dual-frequency GCI is presented to ensure the symmetry of the output power and the stable operation of the system address stability issues. The proposed inverter topology in this article is composed of two inverters in parallel, which are, respectively, a power inverter unit (PIU) and an auxiliary harmonic elimination unit (AHEU). To reduce the switching loss and improve the inverter efficiency, the switching frequency of the PIU is relatively low, injecting current into the grid. Moreover, the feedforward compensation method is used in AHEU. AHEU operates at high switching frequency to generate a current component that is symmetrical with the ripple com-ponent, improving the power quality, without extracting the current harmonic as the current reference. The operating principle of feedforward compensation is explained, and a proper parameter design procedure is presented in this paper. Since L filters are used for the proposed inverter, the system can operate stably where the ratio of switching frequency to fundamental frequency is low. A 10 kW laboratory prototype was built. The experimental results showed that the grid current ripple could be effectively eliminated and the THD of the grid current was 3.01%. The proposed inverter has good stability in a weak grid, and the efficiency of the proposed inverter is 95.98% at rated current, which is 0.81% higher than the traditional GCI, effectively increasing the efficiency of the system.
The Evaluation Prediction System for Urban Advanced Manufacturing Development

Published: August 2023

With the rapid development of the economy, it is important to reasonably evaluate the development status of the regional manufacturing industry. Given this, this article expands the evaluation indicators of urban advanced manufacturing (UAM) from the perspective of the push–pull-mooring (PPM). Then, it uses a machine learning (ML) method to predict the evaluation results of other cities through a small amount of sample data. The results show that: (1) From the current development status of UAM in Guangdong Province (GD), cities in the Pearl River Delta region occupy a dominant position. However, cities in eastern, western, and mountainous regions have strong development potential and lead cities. Therefore, each region has cities with high levels of development and has a demonstrative role. (2) By comparison, it was found that the overall development level of UAM in GD is not significantly different from that of the Yangtze River Economic Belt. However, due to significant differences in their extreme values, the proportion of cities above the average in the overall population is relatively small. This indirectly proves that GD’s UAM not only has a phased nature, but also has a demonstrative role. (3) The prediction effect of the perceptron model is better than other methods. Although neural network models have better prediction performance than other machine learning models, they should not overly rely on complex network structure prediction data. By comparing the results, the reliability is verified. Finally, according to the life cycle theory, we propose a targeted development path for different UAM.

Published: August 2023

The frequency of dogs becoming ill or dying from accidental exposure to cyanotoxins, produced by cyanobacteria, is increasing throughout the United States. In January and February of 2021, two dogs died and five dogs became ill after swimming in Lake Travis, central Texas, USA; one deceased dog (C1) was subjected to pathological testing. Algal materials, sediment samples, zebra mussel viscera, periphyton from shells, as well as fluids and tissues from the digestive tract of C1 were investigated for the following cyanotoxins: anatoxin-a, homoanatoxin-a, dihydroanatoxin-a (dhATX), cylindrospermopsin, saxitoxin, and microcystins. Necropsy results of C1 indicated neurotoxicosis with significant levels of dhATX in the duodenum tissues (10.51 ng/g dry weight (DW)), jejunum tissue (6.076 ng/g DW), and stomach contents (974.88 ng/g DW). Algae collected near the site of C1’s death contained levels of dhATX, ranging from 13 to 33 µg/g. By comparison, dhATX was detected at much lower concentrations in sediment samples (310.23 ng/g DW) and the periphyton on zebra mussel shells (38.45 ng/g DW). While dhATX was suspected in the deaths of canines from an event in Texas in 2019, this is the first report linking dhATX neurotoxicosis through pathological findings in Texas and potentially in the United States.

Published: August 2023

Astroviruses (AstV) and adenoviruses (AdV) are associated with diarrhoea in young animals. However, the epidemiology and genetic diversity of AstVs and AdVs in animals is not well studied. Hence, the present study was conducted to detect and characterize AstVs and AdVs in calves, piglets and puppies from Western Maharashtra, India. Out of the processed porcine (48), canine (80), and bovine (65) faecal samples, the porcine AstV (PAstV), bovine AstV (BAstV), canine AstV (CAstV), and porcine AdV (PAdV) were detected in 12.5%, 7.69%, 3.75% and 4.1% of samples, respectively. In the RNA-dependent RNA polymerase region-based phylogenetic analysis, the detected BAstV strains grouped with MAstV-28, MAstV-33, and MAstV-35, CAstV strains belonged to MAstV-5; PAstV strains belonged to MAstV-24, MAstV-26, and MAstV-31. However, in hexon gene-based phylogeny, both the detected PAdV were of genotype 3, exhibiting 91.9–92.5% nucleotide identity with Ivoirian and Chinese strains. The study reports first-time BAstVs from calves and PAdV-3 from piglets in India. The study revealed diversity in the circulation of AstVs in tested animals and AdVs in pigs, and suggested that they alone might be associated with other diarrhoea or in combination with other enteric pathogens, thus highlighting the necessity of extensive epidemiological investigations to develop diagnostic tools and control measures.
Simulation and Prediction Algorithm for the Whole Process of Debris Flow Based on Multiple Data Integration
Authors: Fang Min , Qi Xing
Published: August 2023

In order to solve the problems of large errors and low accuracy in debris-flow forecasting, the simulation and prediction algorithm for the whole process of debris flow based on multiple data integrations is studied. The middleware method is used to integrate multiple GIS data sets, and the GIS spatial database after multiple data integrations is used to provide the basis of data for the whole process simulation and prediction of debris flow. The spatial cellular simulation model of debris flow is built using the cellular automatic mechanism. The improved kernel principal component analysis method is used to reduce the dimension of debris-flow prediction index data. The reduced dimension index data is input into the support vector machine, and the support vector machine is used to output the prediction results of debris flow in the space cell simulation model of debris flow. Through the simulation visualization technology, the dynamic display of the simulation prediction of the whole process of debris flow is carried out. The experimental results show that the algorithm can realize the simulation of the whole process of debris-flow changes, that the prediction results of debris flow are close to the actual results, and that the error is less than 5%, which improves the prediction accuracy of debris flow and can be used as the auxiliary basis for relevant decision-making departments.
Selection Frameworks for Potential Rainwater Harvesting Sites in Arid and Semi-Arid Regions: A Systematic Literature Review
Authors: Ahmed Safaa , Jesson Mike , Sharifi Soroosh
Published: August 2023

Water shortage is a concern in arid and semi-arid regions across the globe due to their lack of precipitation and unpredictable rainfall patterns. In the past few decades, many frameworks, each with their own criteria, have been used to identify and rank sites for rainwater harvesting (RWH), a process which is critical for the improvement and maintenance of water resources, particularly in arid and semi-arid regions. This study reviews the present state of the art in rainwater harvesting site selection for such regions and identifies areas for additional research. The results of a systematic review performed based on two major databases of engineering research, Scopus and Engineering Village, are presented. Sixty-eight relevant studies were found and critically analysed to identify patterns and unique features in the frameworks used. The results of this study show that 41% of the frameworks consider both biophysical and socioeconomic criteria, whereas the remaining 59% of the frameworks depend on biophysical criteria alone. The importance of each criterion is encapsulated through a suitability score, with 21% of the frameworks using a binary (0 or 1) indicator of whether the site matches a criterion or not and the other frameworks using graded scales of differing granularities, with 52% using a low-resolution scale of 1 to 3, 4, or 5, 7% using a medium-resolution scale of 1 to 10, and a further 7% using a high-resolution scale of 1 to 100. The remaining 13% of the frameworks did not specify the scale used. Importantly, this paper concludes that all existing frameworks for selecting RWH sites are solely based on biophysical and/or socioeconomic criteria; ecological impacts, the consideration of which is vital for building RWH systems sustainably, are currently ignored.

Authors: Quaranta Emanuele , Ramos Helena M. , Stein Ulf
Published: August 2023

During the Digital Decade, the European Union (EU) is facing two important challenges: the green (and energy) transition and the digital transition, which are interconnected with one another. These transitions are of high relevance in several aspects of our life, e.g., in the industry, energy sector, transports, environmental management and our daily life. Digital technologies are particularly emerging also as multi-benefit solution in the water sector, as water is becoming more and more vulnerable to climate change (e.g., droughts and floods) and human activities (e.g., pollution and depletion). Within this context, in this study we assessed some of the several economic benefits that digital solutions can bring to the water sector, with a focus on leakage reduction in water distribution networks, reduction of combined sewer overflows and improvement of hydropower generation and operation. The benefits are calculated for each EU Member State and the UK, and then aggregated at the EU scale. Benefits were quantified in EUR 5.0, 0.14 and 1.7 billion per year (EUR 13.2 per person per year, on average), respectively, excluding environmental and social benefits, which may play a non-negligible role.
Examination of an Electrified Bar Rack Fish Guidance Device for Hydropower Turbines

Published: August 2023

The potential of hydropower turbines to cause injury or mortality to fish is a concern. To reduce this risk, engineers have begun to develop a conically arranged, cantilevered electrified bar rack (Center Sender). This device is proposed to be mounted within the intake of a turbine, guiding downstream-passing fish towards the center of the turbine where blade velocities are lower and blades are thicker, likely reducing the potential for fish to be injured. A simplified version was installed in a flume for testing with Rainbow trout (Oncorhynchus mykiss) while examining several parameters such as electrification, bar spacing, bar angle, and water velocity. The most effective settings were observed to be a water velocity of 1.0 m s−1 with all bars installed at an angle of 40° with electrification on. Other combinations were still effective but had varying results. A minimal proportion (2.3%) of fish passed at lower velocities with bars electrified and mounted at 20°, suggesting that while it functions well as a guidance device in high-velocity conditions, it performs better as a barrier at lower velocities. The study suggests that the Center Sender has promising potential for reducing the harmful effects of hydropower turbines on fish populations by guiding them away from stressors. Further research is needed, but current results encourage its potential use in hydropower operations.
Characteristics of Nitrogen in Overlying Water and Sediment of Typical Agricultural Drainage Ditches during Different Periods in a Freezing-Thaw Area of China

Published: August 2023

In the Sanjiang Plain, agricultural drainage ditches effectively alleviate agricultural non-point source nitrogen pollution. However, limited information is known about the characteristics of bidirectional trans-ports of nitrogen between sediment and overlying and pore water in different patterns of ditches undergoing seasonal freezing-thawing cycles. It is vital to better understand nitrogen interception and purification by ecological ditches. In order to clarify the interception of ecological ditches on internal and external nitrogen, overlying water and sediment samples of two typical agricultural ditches were collected and analyzed in Sanjiang Plain during the growing seasons of 2015–2017. The results indicated that the N-NO3− in overlying water, which was higher than N-NH4+, was the dominant inorganic nitrogen, whilst, in the sediment, N-NH4+ was much higher than N-NO3−, which should be attributed to the soil’s adsorption of N-NH4+. In contrast to the dryland ditch, the paddy ditch had a more significant amount of inorganic nitrogen both in overlying water and sediment, which means that the non-point source nitrogen pollution caused by paddy fields was more severe than that of drylands. Compared with dryland ditches, N-NH4+ in the sediment of pad ditches seemed to be much easier to migrate to a deeper layer, which may cause a greater risk of nitrogen pollution to groundwater. Both in the overlying water and the sediment of ditches, nitrogen content fluctuated during different periods, and inter-annual variation was noticeable, which results means that estimation or prediction of the non-point source pollution output needs to extend the monitoring period and increase sampling frequency to reduce the great uncertainty. The findings may provide a foundation for forecasting agricultural nitrogen pollution and guide best management practices (BMPs) of non-point source nitrogen pollution control in seasonally frozen areas.

We present the first record of Holocene fossil insect assemblages from Central Yakutia. A stratigraphic sequence in the locality within the Vilyuy River valley is a buried oxbow. The late Holocene water body inherited an impervious stratum from the late Pleistocene. The organic layer preserved rich fossil assemblages of macrofossils including insects and other invertebrates, plants, and charcoal. The ancient flora and fauna include species that are common in Yakutia as well as those that are rare and absent in the region. The most abundant finds are leech cocoons and bogbean seeds. The macrofossils of some insects were found along with remains of their host plants. Despite the absence of intensive human land use in the area, traces of fires were recorded. The oxbow represents the environment of a floodplain wetland that developed separately from the ecosystem of the adjacent sand dunes.

This article discusses the mechanisms of interaction between business (on the example of a large industrial enterprise of PJSC NEFAZ), state authorities of the sub-federal (republican) level (on the example of the Republic of Bashkortostan), local self-government bodies (on the example of the city district of the Republic of Bashkiria of Neftekamsk, which is a single-profile municipal entity) and the social community living on the territory of Neftekamsk. An attempt is made to show the importance of developing mechanisms of interaction between the state, business and society at the regional and local levels through the introduction of the ESG concept at the enterprise of PJSC NEFAZ. Special attention is paid to the use of the new ECG rating project for responsible business (ecology, personnel, government) in improving the efficiency of these mechanisms.

Published: August 2023

The article discusses the issues of the construction and application of smart controlling in public institutions. The relevance of the research topic is determined by the active implementation of controlling in the public administration sector, the development and implementation of electronic SMART control (controlling) for management decision-making in accordance with the implementation of the Departmental Project of the Ministry of Finance of the Russian Federation "Electronic SMART control (controlling) and accounting of public finances for management decisions"5, 6. Along with the generalization and systematization of the best practices of using smart controlling in the commercial sector, taking into account the specifics of public finance management, the article determines that smart controlling should be digital and suggests a methodology for evaluating the effectiveness of using an automated controlling system and an algorithm for calculating such an assessment. In addition, it takes into account the fact that controlling should be permeated with the ideology of risk minimization, for which the article offers a risk map for public institutions, depending on the nature of their occurrence. At the same time, smart controlling should be proactive, which is achieved through the use of artificial intelligence technologies, the level of which in the field of public administration in general and public finance management in particular remains extremely low.

O engajamento público na pesquisa científica em Áreas Protegidas: da pesquisa à gestão
Authors: Nunes Gabrielle Abreu , Pegler Gabriela Francisco , Ranieri Victor Eduardo Lima
Published: August 2023

Há uma ampla gama de terminologias relacionadas ao engajamento público em pesquisas científicas como a ciência cidadã, monitoramento participativo, monitoramento de base comunitária e pesquisa-ação. Muitas destas são utilizadas para se referir a iniciativas promovidas no contexto do ecoturismo e dos diferentes tipos de uso público em áreas protegidas. Tendo em vista essa diversidade de termos, que em muitos casos, são apresentados como próximos ou sinônimos, o objetivo do trabalho foi analisar as correlações existentes entre os mesmos e suas implicações para a gestão. A partir de uma Análise de Conteúdo, discutimos nossos resultados à luz de quatro categorias relacionadas ao escopo de publicação das iniciativas de participação pública na pesquisa dentro de áreas protegidas - Governança, Operacional, Voluntários e Pesquisa, apresentados como categorias temáticas no presente trabalho. Evidenciamos que cada termo se relaciona de forma diferente frente às categorias, sendo a Ciência Cidadã, a única que tem contemplado todas as quatro. Da mesma forma, foi observado que a utilização de tais conceitos de forma flexível em projetos de pesquisa pode dificultar o mapeamento e a utilização dos dados para a gestão e futuras propostas.
Management of Patients with Gout and Kidney Disease: A Review of Available Therapies and Common Missteps
Authors: Kannuthurai Vijay , Gaffo Angelo
Published: August 2023

Gout, a common form of inflammatory arthritis, is characterized by deposition of monosodium urate crystals in articular and periarticular tissues. Repeated flares of gout cause joint damage as well as significant health care utilization and decreased quality of life. Patients with CKD have a higher prevalence of gout. Treating Patients with CKD and gout is challenging because of the lack of quality data to guide management in this specific population. This often leads to suboptimal treatment of patients with gout and impaired renal function because concerns regarding the efficacy and safety of available gout therapies in this population often result in significant interphysician variability in treatment regimens and dosages. Acute gout flares are treated with various agents, including nonsteroidal anti-inflammatory drugs, colchicine, glucocorticoids, and—more recently—IL-1 inhibitors. These medications can also be used as prophylaxis if urate-lowering therapy (ULT) is initiated. While these drugs can be used in patients with gout and CKD, there are often factors that complicate treatment, such as the numerous medication interactions involving colchicine and the effect of glucocorticoids on common comorbidities, such as diabetes and hypertension. ULT is recommended to treat recurrent flares, tophaceous deposits, and patients with moderate-to-severe CKD with a serum urate goal of <6 mg/dl recommended to prevent flares. While many misconceptions exist around the risks of using urate-lowering agents in patients with CKD, there is some evidence that these medications can be used safely in Patients with renal impairment. Additional questions exist as to whether gout treatment is indicated for Patients on RRT. Furthermore, there are conflicting data on whether ULT can affect renal function and cardiovascular disease in patients. All of these factors contribute to the unique challenges physicians face when treating patients with gout and CKD.
