Competing with Low Cost Carrier in a Sustainable Environment: Airline Ticket Pricing, Carbon Trading, and Market Power Structure
Authors: Du Peng , Xu Lei , Luo Rou , Hou Mingzhu
Published: January 2024

As the aviation industry embraces the carbon trading market, the competition between full-service carriers and low-cost carriers in ticket pricing is becoming more complicated and worth studying. To this end, we introduce carbon trading into game theoretical models under different market power structures and use real data from China Eastern Airlines and Spring Airlines on the route from Sanya to Shanghai to study this problem. This differs from the existing literature as empirical research is mainly used in this field. Our main results show that the disparity in market power (Stackelberg game) alleviates competition intensity under carbon trading and leads to higher equilibrium prices than in the Nash game model. Meanwhile, even when the two airlines have similar market power, Spring Airlines still has incentives to voluntarily act as a follower of China Eastern Airlines instead of maintaining equal market power with China Eastern Airlines. Under mild regulation, the uplift of carbon prices promotes higher equilibrium prices and supports larger profits. For the sake of consumer welfare, this suggests that the regulation department should impose stricter regulations and grant subsidies to motivate the airlines to mitigate emissions by introducing clean technologies.

Authors: Cudicio Alessandro , Cogliati Marta , Bonardi Alberto , Agosti Valeria , Borgogni Antonio , Orizio Claudio
Published: January 2024

This study examines four tracks (Ts) suitable for handbikes (HBs) in the urban area of Brescia, Italy. WHO physical activity (PA) recommendations challenge kinesiologists to find opportunities to promote exercise in the urban context using HBs. This study aims to characterize T features, assess the physical demands of HB cycling, and promote the use of HBs. Track length, elevation changes, slope, and ascent sections were analyzed. Participants’ physiological engagement during HB cycling was measured. The data were gathered using specialized equipment including a metabolimeter, a power meter, a heart rate monitor, and a cycle computer. Crucially, the findings demonstrate that all four Ts facilitate PA above the recommended threshold (>3 MET) regardless of the speed. The study identifies specific speeds required to achieve vigorous PA (>6 MET) on each T. In summary, this study’s analysis of various tracks reveals their potential to meet PA guidelines, even at a slow pace. Moreover, this research establishes speed thresholds for vigorous PA. This information is valuable for both able-bodied individuals and those with mobility challenges when planning effective exercise routines. Moreover, the findings support municipalities in promoting adapted PA in urban areas, enhancing path usability.
Amish and Non-Amish Farmer Perspectives on Climate Change Causes, Effects, and Adaptation Strategies
Authors: Brock Caroline , Haden Van R.
Published: January 2024

Successful agricultural extension programs on climate change require a better understanding of the diverse and evolving farm population. Amish communities are an increasing constituency of rural populations. Ohio Amish and non-Amish farmers (n = 122) were surveyed on attitudes about weather events, climate change, potential adaptation, and policy strategies. Farmers’ belief in climate change and its associated effects were relatively low compared to other studies, with Amish farmers’ belief in climate change less than half that of their non-Amish counterparts. Farmers also tended to focus on isolated weather events over long-term trends. Respondents expressed more concern about government strategies to address climate change than the biophysical climate change effects, with a strong desire to adapt independently of government policy. These sentiments were more profound among the Amish. Both Amish and non-Amish farmers expressed views about God being in control of the weather and, thus, not a pressing source of concern for them. Results indicate the importance of Christian land stewardship principles and point to future research and outreach possibilities that could develop a better understanding of farmer motivations toward climate friendly practices through interviews and collaborative partnerships to promote conservation behaviors in culturally appropriate ways.
Security and Securitization as Topics in Sustainability and Tourism Research
Authors: Wendt Jan Andrzej , Bógdał-Brzezińska Agnieszka
Published: January 2024

There are many published bibliometric works in the literature on the broadly understood topics of tourism, sustainability, and security (STS). Most of these studies present an indexed approach, showing the impact of works, journals, spatial diversity, and the most frequently published or cited authors. The research and analysis undertaken in our work had a different goal: they were an attempt to answer questions about the degree of interest of researchers in the issue of STS, the dynamics of research devoted to the topics of STS, and internal differentiation in the broadly understood concept of security/danger in STS research. Data from the Web of Science journal database were used for the analysis. To determine the number of articles devoted to the topics of security, tourism, and sustainability, several combined keywords and simple statistical analyses were used. In the last 10, and especially 5 years (2019–2023), in each of the three topic groups, there has been an exponential increase in publications in journals indexed in the WoS database. In the sustainability category, risk and security received the most responses; in the tourism, COVID-19, and risk category; and in the tourism, sustainability, risk, and COVID-19 category. The use of keywords indicated thematic diversity in the field of security in each of the examined categories. The greatest interest among STS researchers was in studies related to the “COVID-19” threat. The results of the analysis allowed us to conclude there is an ongoing process of securitization in tourism research.

Authors: Li Chunhua , Wang Jin , Liu Xincen , Xu Kejian
Published: January 2024

A key means of promoting the high-quality development of karst areas is the maintenance of the area’s ecological security. A full recognition of the special ecological function of karst areas, as well as their significance to the surrounding region’s ecological, economic, and social development, is crucial in strengthening the overall strategic deployment of the national ecological construction and the protection and sustainable development of karst landscapes around the globe. In this study, the karst landscape of Puzhehei, Qiubei County, Wenshan Prefecture, Yunnan Province, China, was used as the research object. This study identified ecological source sites through a combination of morphological spatial pattern analysis and landscape connectivity assessment. As a result, 10 factors were selected to construct a comprehensive ecological resistance surface from the natural environment and socio-economic perspective; the resistance surface was corrected by combining the sensitivity of rocky desertification. An ecological corridor and ecological nodes were identified to construct the ecological security pattern based on the minimum cumulative resistance model and circuit theory. The results show that (1) the source areas of the Puzhehei karst landscape ecological protection comprised 11 core area patches with the landscape connectivity index of (dPC) ≥ 10, with a total area of 166.6572 km2, which constituted 46.06% of the total study area, and the ecological source area totaled 77.275 km2, or 21.36% of the total study area; (2) there were 78 potential ecological corridors in the Puzhehei karst region, with a total length of 545.186 km, including 12 key corridors and 66 general corridors; (3) a total of 51 ecological nodes were identified, including 11 “source-type ecological nodes”, 30 “ecological pinch points”, and 10 “ecological obstacles”, including 16 key ecological nodes. This study provides a theoretical basis for the integration of Puzhehei Nature Reserve, as well as a reference for the ecologically sustainable development of similar karst areas.

Published: January 2024

With the accelerated process of urbanization, air pollution has become increasingly severe. Garden plants can trap atmospheric particulate matter, which is of great significance for improving the urban ecological environment and promoting sustainable development. To investigate the dust retention effect of typical transportation green spaces in Nanjing, this study focuses on thirteen garden plants on Xuanwu Avenue in Nanjing. The dust retention capacity of these plants was determined using the wash-off method, while the microstructure of their leaf surfaces was observed using scanning electron microscopy. The results are as follows: Firstly, per unit leaf area, Liriope spicata, Ophiopogon japonicus, and Viburnum odoratissimum demonstrate solid dust retention abilities. Additionally, Viburnum odoratissimum, Prunus serrulata var. Lannesiana, and Liriope spicata show strong dust retention abilities per single leaf. Moreover, Platanus acerifolia, Viburnum odoratissimum, and Cinnamomum camphora have strong dust retention abilities per plant. Viburnum odoratissimum, Platanus acerifolia, and Prunus serrulata var. Lannesiana exhibit the most substantial dust retention capacities. Secondly, there is a significant negative correlation between dust retention per plant and the potassium content, while a significant positive correlation is observed with plant height, canopy height, and leaf width. Furthermore, there is a highly significant positive correlation between dust retention per unit leaf area and stomatal length and a highly significant negative correlation with leaf length. The surface microstructure of the blade mainly increases the dust retention capacity of the blade by increasing the friction of the leaf surface. Lastly, specific leaf surface microstructures, such as grooved epidermis and trichomes, enhance plants’ dust retention capacity. Consequently, for the future configuration of road green spaces in Nanjing, a mixed planting mode of trees, shrubs, and grass is recommended. Priority should be given to selecting plants with strong overall dust retention capabilities, such as Platanus acerifolia, Viburnum odoratissimum, and Prunus serrulata var. Lannesiana, to alleviate air pollution, improve the urban ecological environment, and achieve sustainable development.

Published: January 2024

In the near future, the incorporation of shared electric automated and connected mobility (SEACM) technologies will significantly transform the landscape of transportation into a sustainable and efficient mobility ecosystem. However, these technological advances raise complex scientific challenges. Problems related to safety, energy efficiency, and route optimization in dynamic urban environments are major issues to be resolved. In addition, the unavailability of realistic and various data of such systems makes their deployment, design, and performance evaluation very challenging. As a result, to avoid the constraints of real data collection, using generated artificial datasets is crucial for simulation to test and validate algorithms and models under various scenarios. These artificial datasets are used for the training of ML (Machine Learning) models, allowing researchers and operators to evaluate performance and predict system behavior under various conditions. To generate artificial datasets, numerous elements such as user behavior, vehicle dynamics, charging infrastructure, and environmental conditions must be considered. In all these elements, symmetry is a core concern; in some cases, asymmetry is more realistic; however, in others, reaching/maintaining as much symmetry as possible is a core requirement. This review paper provides a comprehensive literature survey of the most relevant techniques generating synthetic datasets in the literature, with a particular focus on the shared electric automated and connected mobility context. Furthermore, this paper also investigates central issues of these complex and dynamic systems regarding how artificial datasets could be used in the training of ML models to address the repositioning problem. Hereby, symmetry is undoubtedly a crucial consideration for ML models. In the case of datasets, it is imperative that they accurately emulate the symmetry or asymmetry observed in real-world scenarios to be effectively represented by the generated datasets. Then, this paper investigates the current challenges and limitations of synthetic datasets, such as the reliability of simulations to the real world, and the validation of generative models. Additionally, it explores how ML-based algorithms can be used to optimize vehicle routing, charging infrastructure usage, demand forecasting, and other important operational elements. In conclusion, this paper outlines a series of interesting new research avenues concerning the generation of artificial data for SEACM systems.
An Overview of the Searches for the Violation of the Charge-Parity Symmetry in the Leptonic Sector
Authors: Galymov Vyacheslav
Published: January 2024

The existence of a violation of the Charge-Parity (CP) symmetry in the laws of physics is one of the cornerstone conditions for the generation of a matter–antimatter imbalance necessary to the creation of a matter-dominated universe. The first experimental evidence of the fact that this symmetry is broken in nature was obtained in 1964 in the observations of the decays of neutral kaon mesons. The magnitude of CP violation in the quark sector was measured with an increasing precision exploring also decays of other mesons. However, CP violation in the quark sector alone is not sufficient to explain the formation of matter-dominated universe, and additional sources are required. One such potential source is the lepton sector, where the CP violation could be observed by studying neutrino oscillations with neutrino beams generated by particle accelerators. This article reviews the present efforts in this direction. The results obtained in the ongoing experiments, T2K in Japan and NOvA in USA, are discussed. Additionally, the search for leptonic CP violation is one of the key goals in the programs of future experiments, DUNE in USA and Hyper-Kamiokande in Japan. These experiments and their prospects for its discovery are also presented.

Published: January 2024

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous and persistent environmental contaminants originating from many everyday products. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are two PFAS that are commonly found at high concentrations in aquatic environments. Both chemicals have previously been shown to be toxic to fish, as well as having complex and largely uncharacterized mixture effects. However, limited information is available on marine and estuarine species. In this study, embryonic and larval sheepshead minnows (Cyprinodon variegatus) were exposed to several PFAS mixtures to assess lethal and sublethal effects. PFOS alone was acutely toxic to larvae, with a 96 h LC50 of 1.97 mg/L (1.64–2.16). PFOS + PFOA resulted in a larval LC50 of 3.10 (2.62–3.79) mg/L, suggesting an antagonistic effect. These observations were supported by significant reductions in malondialdehyde (105% ± 3.25) and increases in reduced glutathione concentrations (43.8% ± 1.78) in PFOS + PFOA exposures compared to PFOS-only treatments, indicating reduced oxidative stress. While PFOA reduced PFOS-induced mortality (97.0% ± 3.03), perfluorohexanoic acid (PFHxA) and perfluorobutanoic acid (PFBA) did not. PFOS alone did not affect expression of peroxisome proliferator-activated receptor alpha (pparα) but significantly upregulated apolipoprotein A4 (apoa4) (112.4% ± 17.8), a downstream product of pparα, while none of the other individually tested PFAS affected apoa4 expression. These findings suggest that there are antagonistic interactions between PFOA and PFOS that may reduce mixture toxicity in larval sheepshead minnows through reduced oxidative stress. Elucidating mechanisms of toxicity and interactions between PFAS will aid environmental regulation and management of these ubiquitous pollutants.
Practical Strategies to Reduce Ochratoxin A in Foods
Authors: Lee Hyun Jung , Kim Hae Dun , Ryu Dojin
Published: January 2024

Ochratoxin A (OTA), a potent nephrotoxin, is one of the most deleterious mycotoxins, with its prevalence in agricultural crops and their processed foods around the world. OTA is a major concern to food safety, as OTA exposure through dietary intake may lead to a significant level of accumulation in the body as a result of its long half-life (about 35 days). Its potent renal toxicity and high risk of exposure as well as the difficulty in controlling environmental factors OTA production has prompted the need for timely information on practical strategies for the food industry to effectively manage OTA contamination during food processing. The effects of various food processes, including both nonthermal and thermal methods, on the reduction in OTA were summarized in this review, with emphasis on the toxicity of residual OTA as well as its known and unknown degradation products. Since complete removal of OTA from foodstuffs is not feasible, additional strategies that may facilitate the reduction in OTA in food, such as adding baking soda and sugars, was also discussed, so that the industry may understand and apply practical measures to ensure the safety of its products destined for human consumption.

In Cuba, despite a high sero-prevalence of bluetongue virus (BTV), circulating serotypes remain unknown. The aim of this study was to identify circulating BTV serotypes in farms throughout the western region of Cuba. Blood samples were collected from 200 young cattle and sheep between May and July 2022 for virological analyses (PCR, viral isolation and virus neutralization) and genome sequencing. The results confirmed viral circulation, with viro-prevalence of 25% for BTV. The virus was isolated from 18 blood samples and twelve BTV serotypes were identified by sequencing RT-PCR products targeting the segment 2 of the BTV genome (BTV-1, 2, 3, 6, 10, 12, 13, 17, 18, 19, 22 and 24). Finally, the full genome sequences of 17 Cuban BTV isolates were recovered using a Sequence Independent Single Primer Amplification (SISPA) approach combined to MinION Oxford Nanopore sequencing technology. All together, these results highlight the co-circulation of a wide diversity of BTV serotypes in a quite restricted area and emphasize the need for entomological and livestock surveillance, particularly in light of recent changes in the global distribution and nature of BTV infections.
Utilization of Bacteriophage phi6 for the Production of High-Quality Double-Stranded RNA Molecules
Authors: Levanova Alesia A. , Poranen Minna M.
Published: January 2024

Double-stranded RNA (dsRNA) molecules are mediators of RNA interference (RNAi) in eukaryotic cells. RNAi is a conserved mechanism of post-transcriptional silencing of genes cognate to the sequences of the applied dsRNA. RNAi-based therapeutics for the treatment of rare hereditary diseases have recently emerged, and the first sprayable dsRNA biopesticide has been proposed for registration. The range of applications of dsRNA molecules will likely expand in the future. Therefore, cost-effective methods for the efficient large-scale production of high-quality dsRNA are in demand. Conventional approaches to dsRNA production rely on the chemical or enzymatic synthesis of single-stranded (ss)RNA molecules with a subsequent hybridization of complementary strands. However, the yield of properly annealed biologically active dsRNA molecules is low. As an alternative approach, we have developed methods based on components derived from bacteriophage phi6, a dsRNA virus encoding RNA-dependent RNA polymerase (RdRp). Phi6 RdRp can be harnessed for the enzymatic production of high-quality dsRNA molecules. The isolated RdRp efficiently synthesizes dsRNA in vitro on a heterologous ssRNA template of any length and sequence. To scale up dsRNA production, we have developed an in vivo system where phi6 polymerase complexes produce target dsRNA molecules inside Pseudomonas cells.
Suboptimal MMR Vaccination Coverages—A Constant Challenge for Measles Elimination in Romania
Authors: Stanescu Aurora , Ruta Simona Maria , Cernescu Costin , Pistol Adriana
Published: January 2024

Measles is targeted for elimination since 2001, with a significant reduction in cases recorded worldwide, but outbreaks occur periodically due to immunization gaps. This study analyzes the evolution of vaccination coverage rates (VCRs) in Romania, a EU country with large measles epidemics during the last two decades, including an ongoing outbreak in 2023. Vaccination against measles has been part of the National Immunization Program since 1979, initially as a single dose, and from 1994 onwards it has had two doses. The initially high national VCRs of >97% gradually declined from 2010 onward and remained constantly under 90%, with further decreases during the COVID-19 pandemic. The lowest VCRs for both vaccine doses in the last decade were recorded in 2022 and were 83.4% for the first dose and 71.4% for the second dose, with significant differences among Romania’s 42 counties. Several factors contributed to this decline, including failure to attend the general practitioners’ offices, increased number of children lost to follow-up due to population movements, missed vaccination opportunities due to temporary medical contraindications, a surge in vaccine hesitancy/refusal, a decreasing number of general practitioners and discontinuities in vaccine supply. The persisting suboptimal VCRs in Romania threaten the progress toward measles elimination.

Metropolitan areas in Indonesia, specifically Jabodetabek, are projected to continue experiencing population growth. This will result in increased water demand, which, if left unchecked, could lead to a water crisis. Additionally, the region faces persistent flooding issues. To mitigate these challenges, the Indonesian government proposes the creation of a coastal reservoir. However, a methodology for the pre-feasibility study of such reservoirs in Indonesia is currently lacking. This study addresses this gap by presenting a methodological framework encompassing hydrology and water allocation analyses as well as numerical modeling related to hydraulic and sedimentation aspects of coastal reservoirs. The methodology was designed to be adaptable based on data availability. Finally, this methodology was applied to a case study located at the Cisadane River estuary. The water allocation simulation showed that the reservoir can release an annual optimum discharge of 80.618 m3/s in wet years and 22.731 m3/s in dry years. Flood modeling demonstrated a modest impact on reducing early-hour floods, with a water level decrease of around 20–50 cm within 5 km of the reservoir. Furthermore, sediment modeling revealed varying sedimentation and erosion depths along the rivers, with approximately 62,300 m3/year settling in the reservoir.

Published: January 2024

The Nestos River delta is one of the most important and sensitive basins in Greece and Europe due to its ecosystem functions, combining intensive agricultural production with low-enthalpy geothermal energy and important ecotopes. High water quality is of paramount importance to the sustainability of the system. Systematic and continuous assessment of water quality needs to be carried out in a way that is easy and quick for decision makers and non-expert societal partners to comprehend. In this way, decisions may be made more rapidly, and involved water users may be sensitized to rational water use. To this end, this paper presents the assessment of groundwater quality in the Nestos River’s western delta with the use of Poseidon (PoS), a versatile, index-based method. Groundwater samples collected from 24 and 22 wells tapping the unconfined and the confined aquifers, respectively, in four time periods (May and October 2019 and 2020) were analyzed. Using the PoS index, groundwater samples were classified according to their quality status, highlighting the parameters driving quality degradation issues, thus assisting water managers in obtaining an overview of quality status and evolution through datasets that were often large. PoS index is applied in the study area for the first time and provides a groundwater quality assessment through a unique score representative of the overall water quality status regardless of processes (anthropogenic or natural) or any kind of pressures.
The Impact of Large-Scale Water Diversion Projects on the Water Supply Network: A Case Study in Southwest China

Published: January 2024

The uneven spatial and temporal distribution of water resources has consistently been one of the most significant limiting factors for social development in many regions. Furthermore, with the intensification of climate change, this inequality is progressively widening, posing a critical challenge to the sustainable development of human societies. The construction of large-scale water projects has become one of the crucial means to address the contradictions between water supply and demand. Thus, evaluating the functional aspects of water source network structures and systematically planning the layout of engineering measures in a scientifically reasonable manner are pressing issues that require urgent attention in current research efforts. Addressing this, our study takes the Erhai Lake basin and the surrounding areas in southwest China as the study area and combines landscape ecology and network analysis theory methods to propose a water supply network analysis method that takes into account both structure and node characteristics. Based on this methodology, we analyze the connectivity characteristics of water supply networks in the Erhai region under current (2020) and future (2035) planning scenarios. The results show that there were 215 nodes and 216 links in the water supply network of the Erhai Lake basin in 2020; with the implementation of a series of water conservancy projects, the planned 2035 water supply network will increase by 122 nodes and 163 links, and the connectivity of the regional water network will be significantly improved. Also, we identify some key nodes in the network, and the results show that the water supply network in 2035 will have obvious decentralization characteristics compared with that in 2020. And, based on the network degradation analysis, we find that with the implementation of engineering measures, the resilience of the water supply network will be significantly strengthened by 2035, with stronger risk tolerance. This study extends the quantitative representation of water source network characteristics, which can provide a useful reference for water network structure planning and optimization.
Study on the Optimization of Wujiang’s Water Resources by Combining the Quota Method and NSGA-II Algorithm
Authors: Qu Yongyu , Song Bo , Cai Shubing , Rao Pinzeng , Lin Xichen
Published: January 2024

Recently, the Chinese government has implemented stringent water requirements based on the concept of ‘Basing four aspects on water resources’. However, existing research has inadequately addressed the constraints of water resources on population, city boundaries, land, and production, failing to adequately analyze the interplay between water resource limitations and urban development. Recognizing the interconnectedness between urban water use and economic development, a multi-objective model becomes crucial for optimizing urban water resources. This study establishes a nonlinear multi-objective water resources joint optimization model, aligning with the “Basing four aspects on water resources” requirement to maximize urban GDP and minimize total water use. A genetic algorithm (NSGA-II Algorithm) is applied to solve this complex nonlinear multi-objective model and obtain the Pareto solution set, addressing information loss inherent in the traditional water quota method. The model was tested in Wujiang District, an area located in China’s Jiangsu Province that has been rapidly urbanizing over the past few decades, and yielded 50 non-inferior water resource optimization schemes. The results reveal that the Pareto solution set visually illustrates the competition among objectives and comprehensively displays the interplay between water and urban development. The model takes a holistic approach to consider the relationships between water resources and urban population, land use, and industries, clearly presenting their intricate interdependencies. This study serves as a valuable reference for the rational optimization of water resources in urban development.

Published: January 2024

Whilst numerical modelling is commonly used for simulation to check the design of water conveyance, sluicing and spillway structure design, the numerical modelling has rarely been compared with the physical model tests. The objective of this research presented in this paper was to examine the validity and suitability of the numerical computational fluid dynamics (CFD) modeling method within an ANSYS Fluent/CFD R 18.2 software and compare its results with a fully instrumented and well-run physical model test at the 1:45 scale, carried out for Patrind Hydropower Project located in Pakistan. The physical model test was conducted for confirmation and optimization of a natural de-sanding basin, and diversion of suspended sediment-rich flood waters using a bypass tunnel. The numerical simulation was able to reproduce physical model test results and data gathered over a 7-year project operation to an acceptable level of accuracy. A detailed explanation of the approach used in numerical modelling together with analysis of simulation diagrams of ANSYS Fluent/CFD is also presented. The research shows that a 3D numerical model with accurate boundary conditions and mesh size can replace the need for physical model tests.
Partial Relay Selection for Covert Communication in Two-Hop Relay Systems
Authors: Liu Yan , Wu Huihui
Published: January 2024

This paper investigates the impact of relay selection on covert communication performance in a two-hop wireless relay system, where a transmitter intends to transmit messages to a receiver via a selected relay, subjecting to detection from a warden. To this end, we first propose a partial relay selection scheme based on the signal-to-interference-plus-noise-ratio (SINR) at the relay. We then provide theoretical models for the detection error probability, transmission outage probability, and covert rate. We further explore the optimal designs of the transmit power and target transmission rate for the covert rate, subjecting to the constraints of covertness and the upper bound of transmit power. Finally, we provide extensive numerical results to illustrate the covert rate performance via the partial relay selection scheme in a two-hop relay system.

Ожирение тесно ассоциируется с коморбидными заболеваниями, такими как артериальная гипертензия, ишемическая болезнь сердца, сердечная недостаточность, нарушения ритма сердца, и другими патологиями. Сопутствующие ожирению сердечно-сосудистые заболевания оказывают негативное влияние на качество и продолжительность жизни пациентов. В то же время многими исследователями отмечен лучший прогноз по сердечно-сосудистым событиям и общей смертности у субъектов с избыточной массой тела и ожирением по сравнению с людьми, имеющими нормальный вес или сниженную массу тела. Такая клиническая ситуация получила название парадокса ожирения. Парадокс ожирения продемонстрировали результаты ряда исследований, в которых оценивали зависимость риска смертности и других неблагоприятных клинических исходов от величины индекса массы тела у пациентов с различными сердечно-сосудистыми заболеваниями. Индекс массы тела имеет ограниченную информативность, так как не отражает состав тела и распределение жировой ткани. Вместе с тем кардиометаболический риск определяется преимущественно величиной висцеральной жировой ткани. С другой стороны, значение индекса массы тела зависит не только от содержания жировой ткани, но и от количества мышечной массы в организме человека. В свою очередь, от величины мышечной массы зависит функциональное состояние пациентов, в частности кардиореспираторная выносливость. Дальнейшие исследования с оценкой состава тела и функциональных показателей пациентов необходимы для выяснения причины парадокса ожирения.

Obesity is closely associated with comorbid diseases such as arterial hypertension, coronary heart disease, heart failure, cardiac arrhythmias, and other pathologies. Obesity- related cardiovascular diseases have a negative impact on the quality and life expectancy of patients. At the same time, many researchers have noted a better prognosis for cardiovascular events and overall mortality in overweight and obese subjects compared to people with normal weight or reduced body weight. This clinical situation is called the obesity paradox. The obesity paradox was demonstrated by the results of a number of studies that assessed the dependence of the risk of mortality and other adverse clinical outcomes on the value of body mass index in patients with various cardiovascular diseases. The body mass index has limited information value, as it does not reflect the composition of the body and the distribution of adipose tissue. However, cardiometabolic risk is determined mainly by the amount of visceral adipose tissue. On the other hand, the value of the body mass index depends not only on the content of adipose tissue, but also on the amount of muscle mass in the human body. In turn, the functional state of patients, in particular, cardiorespiratory fitness, depends on the size of muscle mass. Further studies evaluating the body composition and functional parameters of patients are needed to elucidate the cause of the obesity paradox.
Anatomical and Physiological Aspects of the Formation of Reflexogenic Zones of the ENT Organs and the Probability of Cardiac Dysrhythmias During Surgeries in Children

Лор-органы анатомически являются главными воротами организма, обеспечивающими взаимосвязь внешней среды с организмом, и очень тесно связаны с экологической средой. Они в первую очередь подвергаются различным неблагоприятным температурным, токсическим, химическим, бактериологическим воздействиям. В процессе эволюции в них развились механизмы, с помощью которых они осуществляют важнейшие функции регуляции деятельности внутренних органов с внешней средой. Среди этих функций немаловажную роль играет рефлекторная функция. Слизистая оболочка полости носа, глотки и гортани очень богата чувствительными нервными окончаниями, которые не только реагируют на внешнее воздействие, но и рефлекторно связаны со многими внутренними органами и системами организма. Анатомо-физиологические особенности иннервации операционного поля, индивидуальные характеристики рефлекторной активности, обусловленные состоянием надсегментарных и сегментарных механизмов регуляции деятельности внутренних органов, особенности оказания анестезиологического пособия могут явиться предпосылками для развития угрожающих жизни сердечных дизритмий во время оперативного лечения лор-заболеваний.

ENT organs anatomically, they are the main gates of the body, providing the relationship of the external environment with the body and are closely related to the ecological environment. They are primarily exposed to various adverse temperature, toxic, chemical, bacteriological influences. During the evolution, they have developed mechanisms with the help of which they carry out the most important functions of regulating the activity of internal organs with the external environment. The reflex function is among these ones and plays an important role. The mucous membrane of the nasal cavity, pharynx and larynx is very rich in sensitive nerve endings, which not only react to external influences, but are also reflexively connected with many internal organs and body systems. Anatomical and physiological features of the innervation of the surgical field, individual characteristics of reflex activity due to the state of suprasegmental and segmental mechanisms of regulation of the activity of internal organs, features of the provision of anesthesia can be prerequisites for the development of life-threatening cardiac dysrhythmias during surgical treatment of ENT diseases.
Entre la proximidad y la distancia.

El artículo se propone contribuir a la reflexión sobre la relación entre las transformaciones contemporáneas de la política social en Argentina, en particular del registro socio-asistencial, y las prácticas profesionales en Trabajo Social. Bajo una aproximación exploratoria, sostenida en el análisis documental, ponemos en foco los tipos de acción social que surgen de tres tendencias simultáneas de cambio: la territorialización de la asistencia; su monetarización y masificación; y la ampliación de la seguridad social. En este sentido, argumentamos que se han instalado dos lógicas diferenciadas de intervención socio-asistencial, en la proximidad y en la distancia, que convocan a la profesión de manera diferencial. El escrito caracteriza ambas lógicas, las demandas y exigencias hacia profesionales en Trabajo Social que ellas suponen, así como las controversias alrededor del par proximidad/distancia generadas en el proceso. Las conclusiones recuperan dichas discusiones para proponer un modo de conceptualización no esencialista y no excluyente de dicho par categorial.
