Development of environmental management accounting system: a conceptual approach
Authors: Medeckytė Kamilė , Tamulevičienė Daiva
Published: May 2023

With the rise of environmental problems caused by human activities, such as misuse of natural resources, rapid deforestation, and discharge of radioactive and other chemical waste into water bodies, soil and the atmosphere, environmental management accounting has emerged as a tool for promoting sustainable development and reducing negative environmental impacts in businesses. This area of accounting provides a means for analyzing, assessing, controlling, and managing the environmental performance of companies. However, there is a dearth of studies in the scientific literature that systematically assess the potential for introducing and developing environmental management accounting in an enterprise. Therefore, this study aims to identify the areas, instruments, outcome, impact measures, and other elements of environmental management accounting, and integrate them in a targeted manner to develop a conceptualized environmental management accounting system. The results of the literature review and systematic analysis are summarized to provide a conceptual framework for an environmental management accounting system consisting of the following elements: 1) objectives; 2) inputs; 3) processes; 4) outputs/outcomes; 5) feedback; and 6) external environmental conditions. The introduction of such a system would improve the development of environmental management accounting for the long-term sustainability and eco-efficiency of companies.

Published: May 2023

Abstract This paper analyses the students’ experience in relation to schools occupancy movements in 2015 and their perceptions and opinions on educational policy of the State of São Paulo from 1995 to 2018. We conducted a documentary and bibliographic research on São Paulo’s educational policy and interviews with former high school students who participated in schools occupancy. The concept of “experience” is used for the analysis of empirical material and the notion of New Public Management (NPM) under the influence of neoliberalism is used to understand educational policy. We verified that students, based on their experiences, formulated criticisms and expectations regarding the programs and projects of the São Paulo State Secretariat of Education (SEE-SP). They are criticisms that defend a universal, plural and democratic school as opposed to managerialism and the New Public Management.

Published: May 2023

Post-combustion in the reacting plume of a typical solid rocket motor (SRM) is characterized by the emission of high-temperature gases including pollutants such as hydrochloric acid and chlorine together with particles of alumina associated with the combustion of aluminum impregnated in the original propellant. In this paper, methods of modeling the reacting plume of an experimental rocket engine,
proposed by AVIO S.p.A., are studied, where the post-combustion location and temperature estimates are of particular interest. The chemical kinetics have been simulated using the laminar finite rate (LFR) and eddy dissipation concept (EDC) models and a comparison of results for both chemical kinetic models with alumina particles is presented, together with results for a non-reacting plume and predictions from the chemical equilibrium analysis (CEA) program. The results indicate the presence of a post-combustion region downstream of the nozzle exit where temperatures of around 3000 K have been achieved.

Evaluation of Kovacs 1988 Regional Maximum Flood Method
Authors: du Plessis J A , Masule S
Published: May 2023

Estimation of design flood peaks is required for the design and evaluation of hydraulic structures. Methodologies developed between the 1960s and the late 1980s, such as the Regional Maximum Flood (RMF), are used to estimate extreme flood peaks in South Africa. The RMF method uses envelope curves to estimate the maximum flood that can be expected in a specific region in South Africa and neighbouring countries, and represents an indicative upper flood limit for other flood estimation methods. The method developed by Kovacs for South Africa was last updated in 1988. Using more than 30 years of additional data for analysis, this paper highlights the RMF's perceived shortcomings. In two RMF regions, updated observed flood peaks exceeded the existing envelope curves. In 78% of the catchment areas of the evaluated stations, the station RMF values were at least 50% more than the observed maximum flood peak. When the different parameters from the Kovacs 1988 and present DWS (Department of Water and Sanitation) datasets were compared, 98% of the evaluated stations had different flood peaks recorded/reported, while 33% of the stations logged different catchment area sizes. Kovacs 1988 ratios used to estimate flood peaks at different probabilities of occurrence, using the RMF, were found to generally over-estimate expected flood peaks. It is concluded that the 1988 RMF method needs to be updated to still provide relevant guidance.
Hyperspectral core scanner: An effective mineral mapping tool for apatite in the Upper Zone, northern limb, Bushveld Complex
Authors: Mandende H. , Ndou C. , Mothupi T.
Published: May 2023

The technological advances in efficient, rapid, and non-destructive hyperspectral core logging systems for systematic mineral mapping have led to the discovery and exploitation of new mineral deposits Hyperspectral imaging in the long-wave infrared range has been recently used successfully to identify various phosphate-bearing minerals (monazite, xenotime, and britholite), with limited work on apatite associated with mafic-ultramafic layered intrusions. In this study we investigate the effectiveness of a hyperspectral imaging (HSI) system with long-wave infrared (LWIR) bandwidthsto identify apatite in the Upper Zone of the Bushveld Complex. The accuracy of the HSI results was validated by mineralogical and geochemical data. The two apatite-enriched zones detected by HSI suggesting widespread development of apatite throughout the uppermost 600 m of the Upper Zone. The lower apatite-enriched zone is approximately 40 m thick, while the upper apatite-enriched zone is about 23 m thick, consistent with previous thickness determinations by traditional logging and analytical methods. Spectral mixing observed in the response of apatite is ascribed either to the common association of apatite and olivine in these rocks, or to differences between the spatial resolution of the hyperspectral image and the size of apatite grains. The VNIR-SWIR wavelength region did not show prominent spectral features of apatite. Nonetheless, HSI in the LWIR range is effective in mapping apatite and should therefore be considered as an exploration tool. This research advances our knowledge of the reflectance spectroscopy of REE-bearing minerals, which makes it easier to detect, identify, and quantify REE-bearing silicate minerals by HSI.
The necessity of 3D analysis for open-pit rock slope stability studies: Theory and practice
Authors: McQuillan A. , Bar N.
Published: May 2023

Geotechnical models developed during the planning stages of open pit mines are three-dimensional so as to capture the spatial variation in lithological, structural, hydrogeological, and geomechanical conditions. Geological models that describe the lithological and structural (faulting and folding) characteristics of a deposit are always 3D. Likewise, boreholes and piezometers used to develop geomechanical properties and groundwater models are drilled at spatial offsets across the deposit to understand the lateral and vertical characteristics. Yet when geotechnical analysis is completed, often the three-dimensional geological, hydrogeological, and structural models as well as geometrically complex 3D mine designs for optimizing economic mineral recovery and overburden removal are simplified to two-dimensional sections. In this paper we demonstrate that this simplification can lead to the wrong failure mechanism being identified, analysed, and/or a conservative factor of safety being calculated and hence an over-estimation of slope stability. Through case studies we show how three-dimensional analysis methods are more suited to rock slopes, particularly those with anisotropic material strength, when singularities such as geological faults are present, and nonlinear slope geometry. When the same slopes are analysed in two dimensions, the failure mechanism calculated is often fundamentally incorrect. The case studies further reveal that the factor of safety calculated in three dimensions is not always higher than the two-dimensional factor of safety.

Come disegnare la dieta ideale per un paziente dislipidemico
Authors: Sacchitelli Francesca
Published: May 2023

L’alimentazione non corretta, il sovrappeso e l’obesità sono importanti fattori di rischio per l’insorgenza delle dislipidemie secondarie, che a loro volta rientrano tra le patologie responsabili delle prime cause di morte in Italia. Gli esperti della nutrizione hanno il compito di guidare i pazienti verso il raggiungimento del peso ideale e del miglioramento del profilo lipidico ed ematochimico in generale. Studi dimostrano come un dimagrimento di 5 Kg porta a una riduzione significativa dei livelli di colesterolemia e trigliceridemia con effetti positivi anche sul quadro ipertensivo. Inoltre, la scienza riporta costantemente studi che dimostrano l’efficacia puntuale dei singoli alimenti o gruppi di alimenti nel trattamento delle dislipidemie secondarie. L’aspetto nutrizionale dunque è oggi considerato facente parte del processo assistenziale dei pazienti e deve essere concretizzato attraverso decisioni chiare e obiettivi specifici. I piani nutrizionali devono essere bilanciati e allo stesso tempo si deve porre attenzione all’eventualità di raccomandare specifici gruppi alimentari o escluderne altri.
Lipoproteina(a): determinante misterioso di rischio atero-trombotico
Authors: Cosentini Elena , Bianconi Vanessa , Ricciutelli Federica , Mannarino Massimo R. , Pirro Matteo
Published: May 2023

La lipoproteina(a) [Lp(a)] è una lipoproteina plasmatica a bassa densità strutturalmente simile ad una particella LDL, ma legata ad una molecola di apolipoproteina(a) tramite un ponte disolfuro. Da studi epidemiologici e genetici è emersa un’associazione diretta lineare tra i livelli circolanti di Lp(a) ed il rischio di malattia cardiovascolare su base aterosclerotica (ASCVD). Pertanto, la misurazione di Lp(a) è considerata rilevante ai fini della stratificazione del rischio cardiovascolare (CV). Più incerte sono invece le evidenze circa il possibile ruolo di Lp(a) come determinante di eventi trombotici venosi. Sulla base di queste premesse, la riduzione dei livelli circolanti di Lp(a) potrebbe rappresentare un elemento cruciale nell’ambito delle strategie di prevenzione CV. Tuttavia, sebbene varie strategie farmacologiche e non siano state proposte a tal fine, nessuna di esse ha mostrato un buon profilo di efficacia, sicurezza, e tollerabilità tale da giustificarne l’esteso impiego nella comune pratica clinica. Inoltre, non vi sono ad oggi studi clinici randomizzati controllati di fase 3 che abbiano dimostrato l’efficacia della riduzione dei livelli circolanti di Lp(a) in termini di riduzione del rischio CV. Lo sviluppo di terapie mirate per la riduzione dei livelli circolanti di Lp(a) rappresenta quindi una sfida attuale nell’ambito delle strategie di prevenzione CV.

In addition, a questionnaire survey and an interview were conducted to investigate students’ perceptions regarding the effectiveness of WA in learning and the challenges they faced during the process. The findings showed students’ positive perception regarding WA’s effectiveness as a learning tool. However, certain challenges such as distraction, poor Internet connection, and poor time management were found to hinder their learning process considerably. Overall, the study highlighted the possibility of successful WA integration in foreign language education with strategies to minimize the challenges and maximize the effectiveness.
The Translation of Quranic Metaphorical Expressions From Arabic Into English
Authors: Rumman Ronza N. Abu , Salem Mohd Nour Al
Published: May 2023

The current study aims at assessing the translation of metaphors in three English translations of the Holy Quran, namely, Al-Hilali & Khan (2000), Y. Ali (2004), and Abdel Haleem (2005). In particular, it investigates the translation strategies adopted by the three translators to render ten Quranic metaphorical expressions into English based on Newmark’s (1988) metaphor translation strategies. Each Quranic metaphor is examined in its context based on the two tafsir (exegesis) books: Tafsir al-Jalalayn and Tanwir al Miqbas min Tafsir Ibn Abbass. The translation strategies employed in the three English translations are assessed in terms of their suitability. The results indicated that the most frequently used strategies to render Quranic metaphors are reproducing the same image in the TL literally, converting metaphor into sense, translating metaphor by simile keeping the image, converting metaphor into simile plus sense, and reproducing the same metaphor combined with sense, respectively. The study concluded that the most efficient translation is the one provided by Al-Hilali & Khan (2000) as they tried to retain the metaphorical image.
Correlations Between Learning Style Preferences and Arab-Speaking Gulf Region First-Year College Students’ EFL Performance: A Literature Review
Authors: Gabriel Raafat
Published: May 2023

This review aims at examining recent and relevant literature that investigates the correlations among learning style preferences, awareness of learning style preferences, motivation, intelligence types, gender, and Arabic Gulf region first-year college students’ EFL performance. A lot of studies about the influence of learners’ awareness of their learning style and motivation types on their ESL (English as a second language) learning performance have been conducted in English speaking Western countries, but fewer similar research studies have been conducted in EFL (English as a foreign language) contexts, particularly in the Arabian Gulf region Arabic-speaking countries and more particularly with first-year college-students as research participants. This review attempts to explore the dominant learning style preferences, main or obvious intelligence types according to the multiple intelligence theory, main motivation type and how the awareness of these could impact the learners’ progress or otherwise in EFL. Due to the relative scarcity of relevant research in the Arabic Gulf region, other studies conducted in neighboring and culturally similar countries were reviewed as well. As a result of examining the literature in this respect, more studies and research are recommended to help learners, instructors, professionals, researchers, and practitioners concerned and involved in EFL in this context.

Authors: Algraini Farah N.
Published: May 2023

This study aimed to investigate the EFL university instructors’ perceptions of online education during the COVID-19 pandemic. The participants were 32; 87.5% of them were females while 12.5% were males. They belonged to many higher educational institutions in Saudi Arabia. Data were collected using an online questionnaire. This questionnaire included four parts which were (1) the participants’ demographic information, (2) the advantages of online education during the COVID-19 pandemic, (3) the disadvantages of online education during the COVID-19 pandemic, and finally (4) the effectiveness of online education during the COVID-19 pandemic. The results revealed that most of the participants had a more dominant positive attitude regarding online learning activities although some of them claimed that there were some negative aspects that should be taken into consideration. Online education is fundamentally characterized by its flexibility, being chargeless, and enabling EFL instructors to think creatively and improve their performance. However, the lack of regulating sinful activities such as cheating, lack of face-to-face social interaction, and poor accessibility to the internet connection were essentially the three significant disadvantages of online education that most of the participants agreed on. Based on the findings obtained, this study provided some recommendations as well as suggestions for further research.

Published: May 2023

Mesatua “storytelling” is a tradition that is usually done by parents or grandparents in Bali. Storytelling uses Balinese folklore, which is rich in moral value. It is an effort to preserve the language and culture and develop Balinese cultural values. This study aims to determine Balinese folklore’s transitivity and social context by applying a systemic functional analysis theory. The result of the analysis showed that transitivity elements consist of process, participant, and circumstances. The situational context consists of the field of discourse, tenor of discourse, and mode of discourse. The cultural context involves mesatua “storytelling” traditions, the level of Balinese language used in the text, and religious symbolic meaning.

Published: May 2023

As part of evolution of single phase to earth faults protection methods and tools in 6–10 kV networks the development of simulation study methods of these networks and their components becomes relevant. A significant direction in this area is upgrading of sensors installed directly on the wires and electrical transmission towers. These sensors are installed in the conditions of an electromagnetic field acting on them and dynamically changes both in time and space, especially during emergency modes including single phase to earth faults. Application of modern software offers a challenge for complex simulation study of electromagnetic fields distribution at the location of the measuring transducers in continuously variable electromagnetic environment. The above-noted statement determines the relevance of the research goal, which is the development of a simulation study method of 6–10 kV overhead power lines, the model of which is designed to study existing and create new single phase to earth fault location algorithms and devices. To solve the tasks set the methods of simulation study of overhead transmission lines and corresponding medium voltage networks in PSCAD and COMSOL Multiphysics software have been used. The general concept of design of a 6–10 kV network and an overhead transmission line simulation model is formulated. The geometrical parameters of the section of the model of an overhead power transmission line to simulate electromagnetic transients are selected, considering the frequency dependence of the line parameters (inductance and active resistance). The proposed model of the overhead transmission line is verified, and recommendations for its application are given. The developed “inductive” component of the proposed overhead transmission line model allows to provide high accuracy of calculation of transient components of currents and voltages during single phase to earth faults. It makes possible to use this model for the development and research of single phase to earth fault location algorithms. The developed approach to simulation study of an overhead transmission line is the field of interest for further research, as it makes it possible to calculate the components of the electric field which are observed during single phase to earth faults.
Method for reducing time of backup power supply in power supply systems with motor load
Authors:   Donetsk National Technical University, Derkachev S.V.
Published: May 2023

Nowadays fast-acting automatic transfer equipment is commonly applied in power supply systems with a motor load since it ensures uninterrupted power supply of critical consumers. However, their application requires the use of high-speed breakers. The implementation of a “high-speed” transfer to a backup power source when using vacuum switches may not be possible due to the long turn-on and turn-off times. Therefore, the purpose of the paper is relevant. The aim of the paper is to study the possibility to reduce the backup power supply time by improving the algorithm to control the vacuum switches of the main and backup power sources in the modes “high-speed” switching by the fast-acting automatic device in case of short circuits in the external power supply network. To achieve this purpose, computer modeling methods are used. They are based on mathematical models of electrical network elements written using systems of differential equations. The authors have defined the regularities of the transient processes in synchronous and induction motors when switching to a backup power source by the fast-acting automatic device in case of short circuits in the external power supply network. It makes possible to set the limit value of the mismatch angle between the residual voltage vectors on the section of the main power source and the voltage of the backup power source, at which the level of the self-starting current does not exceed the values of the starting currents. Also, it makes possible to develop an algorithm to control breakers. The proposed algorithm is based on changing the operation order of the switches of the main and backup power sources. The obtained results show that implementation of the proposed algorithm to control breakers of the main and backup power sources in fast-acting automatic devices in case of short circuits in the external power supply network of the main power source makes it possible to reduce the backup power supply time and decrease the level of self-starting currents that do not exceed the level of starting currents of electric motors without use of high-speed switches.
Preserving vaginal health after treatment for gynecological malignancies
Authors: Kedrova A. G.
Published: May 2023

The prevalence of vaginal atrophy is particularly high among women who have undergone treatment for gynecological cancers, since they have significantly lower estrogen levels and altered vaginal microbiota. These patients often experience vaginal discomfort, dryness, and pain, but rarely report this to a doctor. Such symptoms affect patients’ quality of life and might cause a family breakdown. This article proposes a safe therapeutic option for women with vulvovaginal atrophy resulted from gynecological surgeries or comprehensive treatment for gynecological cancers. It provides a rationale for the local application of Estrogial™ containing hyaluronic acid. Elimination of symptoms, such as burning, itching, swelling, and hyperemia of the vulval vestibule and perineal tissues ensured maximum compliance to treatment in cancer patients and improved their quality of life after combination therapy.

Deficient DNA mismatch repair (dMMR) is a rare molecular disorder found in 20-30 % of endometrial tumors. Laboratory identification of dMMR/microsatellite instability (MSI) has a high diagnostic value, since these impairments are considered as biomarkers of endometrial adenocarcinoma. They help to identify patients at high risk of Lynch syndrome, evaluate the disease prognosis, and estimate the efficacy of immune checkpoint inhibitors and their combinations. This review details current concepts of MSI diagnostics and discusses its predictive value in patients with endometrial cancer. It also describes a new diagnostic algorithm for the detection of dMMR and MSI.
Organ-sparing treatment for breast cancer
Authors: Rasskazova E. A. , Zikiryakhodzhaev A. D. , Kaprin A. D.
Published: May 2023

This article reviews literature on organ-sparing and oncoplastic surgeries for breast cancer. Initially, we performed organ-sparing surgeries in patients with stage I—IIA breast cancer and then compared outcomes with those in patients after radical mastectomy. Since there were no differences in both overall and relapse-free survival between the groups, we started to perform organ-sparing surgeries in women with locally advanced breast cancer after neoadjuvant therapy who achieved complete or partial response. Oncoplastic resections were used to achieve good aesthetic results and also for patients in whom classical organ-sparing resection would inevitably result in a poor cosmetic outcome due to the tumor location. In recent years, the technique of extreme oncoplastic breast resection has emerged as a promising option that extended the scope of indications to organ-sparing treatment. In particular, it allows breast conservation for patients with multicentric, multifocal tumors, and tumors >50 mm. All organ-sparing and oncoplastic operations first of all improve the quality of life of breast cancer patients.

Background. Surgery is fundamental in complex and combined approach in the treatment of the early breast cancer. It is a common fact, that absence of tumor cells in the resection margin is the main indicator of oncological safety of the breast-conserving surgery (BCS). The presence of tumor cells in examined margin is the predictor of local recurrence after BCS for breast cancer. Currently the clinical need for precise and fast method of intraoperative assessment of the resection margin status is kept. Intraoperative evaluation of the resection margin with the usage of digital two-point sectorography (Faxitron PathVision) appeared as the alternative to intraoperative histological examination, providing the optimum size of the information about adequacy of the carried out surgical treatment.

Aim. To evaluate diagnostic features of the digital two-point sectorography Faxitron PathVision in the intraoperative assessment of the resection margin status after the surgical treatment in comparison with planned histologic examination.

Materials and methods. 368 conducted conservative surgeries were analyzed; patients were divided in two groups depending on neoadjuvant chemotherapy. The first group of patients included 236 patients, who didn't receive neoadjuvant chemotherapy before surgery; second group included 132 patients, who received neoadjuvant chemotherapy. Subset analysis of detection rate of the positive resection margin (R1) was carried out with the usage of the intraoperative assessment of the resection margin on the X-ray device Faxitron PathVision or without this method. After each BCS resection margin status was assessed on planned histologic examination for the presence of the tumor cells, with subsequent analysis of the frequency of reoperations when R1 was found.

Results. In 368 tested surgical specimens after BCS R1 was found in 25 cases, which is 6.8 %. From 236 patients in the first group after BCS R1 was found in 20 cases, which is 8.5 %; from 132 conducted operations in the second group in 5 (3.8 %) cases the presence of R1 is found. Reoperations were performed in 13 cases and tumor cells were found in 3 cases in the sub-group which didn't receive intraoperative assessment with X-ray device Faxitron PathVision.

Conclusions. Assessing the results of our study we can make a conclusion about the positive experience of performing BCS and intraoperative evaluation of the resection margin with the usage of the digital two-point sectorography (Faxitron PathVision) and low frequency of R1 (3.8 %) in comparison with absence of this method (8.5 %).

Published: May 2023

Background. One-stage prepectoral implant-based reconstruction (OSPIBR) using biocompatible synthetic meshes support gained wide popularity in breast cancer surgery. Optimal structure of polypropylene mesh implants (PMI) and methods of its application are actively discussed.

Aim. To study the effectiveness and safety of prosthesis support with “heavy” PMI in OSPIBR. 

Materials and methods. During 2019-2021 18 OSPIBR with "heavy" PMI support were performed after subcutaneous mastectomies in 14 patients. Cancer was indication for surgery in 13 cases (two of them - with BRCA1 mutation) and BRCA1 mutation solely - in 1 case. Foamed polyurethane covered silicone prosthesis (Polytech, Germany) was used for OSPIBR and "heavy" PMI PROLENE™ Polypropylene Mesh (Ethicon/Johnson & Johnson, USA) for prosthesis support by original method.

Results. The overall complication rate was 5.6 % (1/18). It was a minor complication: limited aseptic skin necrosis along incision edge, successfully excised under local anesthesia. No cancer recurrences or capsular contracture formation were registrated during follow-up (6 months). The cosmetic outcome (Harvard score) was excellent in 11 of them and good in 3.

Conclusions. "Heavy" PMI application by original technique in OSPIBR after subcutaneous mastectomy for breast cancer is a safe and effective method of prosthesis support.

The purpose of the article is an attempt to create the most general outline of the conceptual model of the regional system of tourist services, as a partial manifestation of the social and geographical system. Method. The researcher has used both general scientific methods, in particular analysis, scientific synthesis, analytical method, methods of comparison and generalization, as well as special ones: modeling and forecasting. Scientific novelty. Under the current conditions, the theoretical and practical significance of geospatial tourism research has to change substantially, since it traditionally focuses on the study of sectoral aspects of tourism suffers from a lack of descriptiveness, not usually rising to the level of proper theoretical and methodological generalizations. The disadvantage of the overwhelming majority of studies, and especially geographic ones, is the insufficient attention to substantiating the nature and specificity of the phenomenon of tourism as a complex, functionally integrated, and at the same time, qualitatively mixed in its internal composition of the system. Practical meaning. The results of this study contribute to the understanding of the relationship between the concepts of "regional socio-economic system" (socio-geographical system) and "regional system of tourist services", which are similar to each other in the principles of construction and organization, the peculiarities of their system-forming connections, which represent the exchange of human (tourist) flows, matter, energy and information between elements within a coherent territory. They can be used for further research of the regional system of tourist services and its component hierarchy.

The essence and features of clustering in rural tourism are considered. An initial analysis of aspects of the creation and functioning of rural tourism clusters in Ukraine (current state, areas of activity, problems and prospects for their further development) was carried out using the methodology of research semi-structured interviews and qualitative content analysis. The characteristics of the researched rural tourism clusters according to the criteria of geographical location, smart specialization, scale of activity, history of creation, features of the tourist product and target audience are given. Trends in the number and composition of participants and features of the institutional design of clusters of rural tourism in Ukraine are analyzed. Groups of clusters of rural tourism have been identified according to the criterion of their own smart specialization. The main purpose of the creation and functioning of rural tourism clusters in the context of their participants and the region of activity has been revealed. The main areas of activity of clusters of rural tourism in Ukraine are determined: organizational, educational, advertising and marketing, communication, creation of a joint tourist product, development of the community and its tourist potential, and direction of cooperation. The possibilities and features of cooperation of rural tourism clusters with state authorities and local self-government bodies, with scientific and educational institutions, with public associations and with other subjects at the local, regional and national levels are revealed. The main problems faced by the clusters during their activities are identified - external, which characterize the general state of tourism development in the region, and internal, which relate directly to the activity of the cluster. The impact of seasonality on the organization of rural tourism cluster activities has been studied. The peculiarities of planning and prospects for the future development of rural tourism clusters and the level of study and use of other available domestic and foreign experience during the organization of their activities are analyzed. The main groups of benefits that cluster participants receive from joint activities are disclosed - social, marketing, access to knowledge and information, financial, access to resources, and benefits related to the tourist product. Factors determining the success of rural tourism clusters are summarized.
Quasi-subjects in cyber law
Authors: Chubukova S. G.
Published: May 2023

The system of subjects of cyber law is in the process of constant development due to the emergence of new digital technologies. An actual theoretical problem is the development of the theory of quasi-subjects in law and the definition of the legal status of an electronic person as a quasisubject of law.

A quasi-subject is a person who does not possess all the characteristics of a subject of law. It is possible to distinguish such types of quasi-subject as persons: endowed with subjective rights and obligations, but not responsible (intellectual agents, cyberphysical systems, artificial intelligence systems, robots); not having legal personality, but realizing their interests through the interests of subjects of law, as a rule, as constitutional and legal imperative (future generations).
Oxygen-binding properties of blood in insulin resistance with different asprosin content
Authors: Zinchuk V.V. , Al-Jebur J.S.O. , Glutkina N.V.
Published: May 2023

The oxygen-binding properties of blood were studied in male patients with insulin resistance (IR) with different levels of asprosin. The content of asprosin, parameters of blood oxygen transport function, as well as gas transmitters, nitrogen monoxide and hydrogen sulfide, were determined in the venous blood plasma. In the studied IR patients with increased blood asprosin content, impaired blood oxygenation was noted; IR patients with normal body weight had increased hemoglobin affinity for oxygen, while in IR patients with overweight and the 1st degree obesity, this parameter decreased. The detected increase in the concentration of nitrogen monoxide and the decrease in hydrogen sulfide may be important for the oxygen-binding properties of the blood and the development of metabolic imbalance.

Published: May 2023

A decrease in a country's export prices and foreign exchange reserves is symptomatic of exchange rate market pressures, which would be described as an oversupply or disequilibrium in the money market. The method used in this study is the Vector Error Correction Model (VECM) to investigate Exchange Market Pressure (EMP) in Indonesia. This study utilizes secondary data obtained from Statistics Indonesia and Bank Indonesia (BI) website since 2008Q1-2021Q4. The findings of this study demonstrate a strong positive long-term relationship between domestic credit growth and the BI rate, a large negative long-term relationship between GDP growth and the BI rate, and no significant relationship between the current account balance and the exchange rate.
