Published: October 2024

Pancreatic tuberculosis (TB) is extremely rare and has similar clinical and radiological findings compared to pancreatic malignancy. Challenges in detecting individuals with pancreatic TB, especially in rural areas with limited supporting resources, are the reasons for a more complete care strategy. We report a case of pancreatic TB in a 25-year-old woman admitted to the emergency department (ED), who was initially suspected of having a pancreatic tumor. Her chief complaints were fever, fatigue, and abdominal pain, while she also experienced weight loss. Exploratory laparotomy and further pathological evaluation suggested pancreatic TB. Subsequently, the patient was given anti-TB drugs and showed clinical improvement. In conclusion, this case report highlighted that pancreatic TB could mimic pancreatic cancer; however, it is a treatable condition. Thus, it is important for physicians to consider this as a differential diagnosis, especially in high-risk populations and in rural areas with limited diagnostic tools.

Authors: Chawla Siddhi , Upreti Lalendra , Halflongbar Thaihamdao
Published: October 2024

Volvulus affecting the gastrointestinal (GI) tract is one of the common causes of recurrent pain in the abdomen, and often, patients present with non-specific abdominal pain associated with nausea and/or vomiting. A high degree of suspicion is required at the clinician’s end to suspect this diagnosis, which is usually confirmed by imaging using radiographs, fluoroscopic evaluation, and computed tomography. Familiarity of the clinician and radiologist with the imaging appearances of these emergent conditions on various imaging modalities is quintessential to avoiding life-threatening complications like bowel ischemia or perforation, which are associated with delayed or missed diagnosis. Our article describes the clinical features and classical imaging of the various types of volvulus affecting different bowel segments in the entire GI tract.

Background: Pancreatic duct (PD) dilation could be presented in both benign and malignant diseases. Endoscopic ultrasonography (EUS) is a sensitive modality that provides both structural assessment and tissue sampling. This study aims to explore the importance of PD dilation as a potential indicator related to various pancreatobiliary pathologies identified via EUS. Methods: Among 3109 subjects who underwent EUS, 599 had evidence of dilated PD and met the inclusion criteria of this retrospective study. Also, the patients underwent EUS fine needle aspiration (EUS-FNA) to evaluate the etiology when required. All data were extracted from patients’ medical records to perform statistical analysis. Results: The study sample revealed 64% being male with a median age was 65-years. Pancreatic adenocarcinoma was the most common etiology diagnosed in 236 patients (39.4%), followed by sphincter of Oddi dysfunction (SOD) in 13% of subjects. Ampullary carcinoma, common bile duct stone, and cholangiocarcinoma were found at 9.5%, 8.8%, and 6.8%, respectively. Abdominal pain was the most common symptom seen in 440 (73.4%) patients. Opium consumption was reported in 170 (28.4%) subjects. Opium consumption was significantly more prevalent in patients with SOD (P<0.05). Conclusion: We suggest that PD dilation could be associated with a wide range of pancreaticobiliary pathologies, especially pancreatic neoplasms. In this regard, PD dilation should be considered as a crucial indicator of pancreatic neoplasm despite it may be associated with no clear etiologies.

Authors: Soheilipour Maryam , Tamizi Far Babak , Fadaei Razieh , Adibi Peyman
Published: October 2024

Background: The possibility of pelvic floor dysfunction (PFD) occurrence seems to be higher in patients with inflammatory bowel disease (IBD) due to the presence of functional gastrointestinal disorders in these patients. Hence, this study aimed to evaluate the association of ulcerative colitis (UC) in women with PFD and its comparison with the healthy (without IBD) population. Methods: The present study was conducted on 150 women with UC and 150 without-IBD individuals. Pelvic Floor Distress Inventory (PFDI-20) was used to evaluate the pelvic floor function. Results: The results of this study revealed that UC had a significant role in increasing not only the PFD score (Beta=3.04; P<0.001) but also the score of each sub-scale of Pelvic Organ Prolapse Distress Inventory (POPDI) (Beta=6.61; P<0.001), Colo-Rectal-Anal Distress Inventory (CRADI) (Beta=9.37; P<0.001), and Urinary Distress Inventory (UDI) (Beta=5.56; P=0.015). In addition, aging, increased body mass index (BMI) and menopause had significant role in increasing POPDI, UDI, and PFDI scores, respectively (P<0.05). Conclusion: The percentage of PFD in women with UC was significantly higher than its percentage in women without IBD. This dysfunction was more visible in the two sub-scales of POPDI and CRADI. In addition to having UC, aging, BMI, and menopause played a significant role in increasing PFD.
The Effect of Ondansetron on Improvement of Symptoms in Patients with Irritable Bowel Syndrome with Diarrhea Domination: A Randomized Controlled Trial
Authors: Jafari Sattar , Atmani Arezoo , Gohari Sepehr , Seifi Ehsan
Published: October 2024

Background: Diarrhea-dominant irritable bowel syndrome (IBS-D) is a deliberating and chronic condition that can impair social activities. Determining proper medication with satisfactory outcomes has been a challenge. The 5-hydroxytryptamine 3 receptor antagonist (5-HT3 RA) drugs have demonstrated favorable outcomes on IBS-D in the last 3 decades. Ondansetron, also a 5-HT3 RA is known as an antiemetic. Our aim was to evaluate the efficacy of ondansetron in IBS-D. Methods: In this single-center, double-blind, randomized controlled trial, patients with IBS-D were recruited. Patients were randomized on a 1:1 ratio and assigned into two groups: imipramine 25 mg/daily plus ondansetron 4 mg/3 times per day and imipramine 25 mg/daily plus placebo. The primary endpoint was the frequency of diarrhea per day after 8 weeks of treatment. The secondary endpoints consisted of changes in the frequency of defecation urgency per day, the number of days with gastrointestinal pain and bloating, and the patients’ overall satisfaction regarding bowel habits after 8 weeks of the treatment. Results: Data from 98 patients were analyzed. Ondansetron, compared to placebo, improved the primary outcome, and the stool consistency was increased significantly (3.29±1.19 vs 4.55±1.17, P<0.001). Moreover, the response rate for the diarrhea frequency was significantly higher in the ondansetron group compared to the placebo (77.5% vs 34.7%, P<0.001). In the ondansetron group, fewer urgencies were experienced, and pain severity and feeling of bloating declined as well (P<0.01). Conclusion: Ondansetron can mitigate almost all IBS-D-related symptoms, which may indicate it as a drug of choice; however, further evidence is required to ascertain its safety.
Clinical Perspectives on the Histomolecular Features of the Pancreatic Precursor Lesions: A Narrative Review
Authors: Kazemi-Harikandei Sayedeh-Zahra , Karimi Amirali , Tavangar Seyed Mohammad
Published: October 2024

Pancreatic cancer (PC) is a lethal cancer with poor prognoses. Identifying and characterizing pancreatic cystic lesions (PCLs) in the early detection and follow-up plans is thought to help detect pancreatic malignancy. Besides, the molecular features of PCLs are thought to unravel potentials for targeted therapies. We present a narrative review of the existing literature on the role of PCLs in the early detection, risk stratification, and medical management of PC. High-grade intraductal papillary mucinous neoplasms (IPMN) and pancreatic intraepithelial neoplasia (PanIN) stage III are high-risk lesions for developing PC. These lesions often require thorough histomolecular characterization using endoscopic ultrasound (EUS), before a surgical decision is made. EUS is also useful in the risk assessment of PCLs with tentative plans–for instance, in branch-duct IPMNs (BD-IPMN)- where the final decision might change. Besides the operative decisions, recent improvements in the application of targeted therapies are expected to improve survival measures. Knowledge of molecular features has helped develop targeted therapies. In summary, the histomolecular characterization of PCLs is helpful in optimizing management plans in PC. Further improvements are still needed for the broad application of this knowledge in the clinical setting.
Troublesome Weight Loss: A Case Report of Large Gastric Phytobezoar
Authors: Esfandiary Rad Ali Mohammad , Malekzadeh Masoud Mohammad
Published: October 2024

Gastric bezoar is a very rare clinical condition and hard to treat. Phytobezoars are one of the most common types of bezoars, which happens with the consumption of indigestible fibers. In this report, we presented an elderly man with gastric phytobezoar who presented with peptic ulcer and was treated successfully with proton pump inhibitor (PPI) and Coca-Cola. Surveillance endoscopy showed a completely healed ulcer. It was shown that cautious use of Coca-Cola can be helpful and safe in treating concomitant phytobezoar and gastric ulcers. To the best of our knowledge, this is the first report of phytobezoar from Iran, which was treated with cola.
Monopoly Reimagined: Cultivating Gaming Literacy for Tackling Real-World Complexities
Authors: Youdelevich Sarit , Hvidsten Adeline
Published: October 2024

Gaming literacy proposes specific ways of thinking and acting by providing cognitive, creative, and social skills, which are necessary in the face of complex (Zimmerman, 2008) and wicked problems we encounter in today’s society (Rittel & Webber, 1973). This paper presents preliminary findings from an exploratory study of how students within arts, design and media might redesign board games and develop gaming literacy; helping them understand and make sense of the world “from the point of view of gaming” (Zimmerman, 2008, p. 156).  Through research-based teaching at both bachelor and master levels, we developed a work-in-progress workshop where students must face complexity and practice navigating it. In the workshop, students redesigned the familiar board game Monopoly, using it as a metaphor, and our emergent findings suggest that it can provide a scaffold that enables students to map, prototype and simulate different complex problems and systems onto it - without prior game design knowledge. Monopoly introduced a balance between familiar and known rules and constraints on one side, and hackability and the freedom of play on the other. The monopoly workshop provides an experimental, hands-on, and collaborative approach to understanding complexity through intertwined actions of exploring, prototyping, testing, and reflecting (Zimmerman, Forlizzi & Everson, 2007). We found that the success of such a process seemingly depends on the facilitator and the participants. Here, allocating time for explicit reflection on learning outcomes was a necessary and vital part of the workshop (Alme & Hvidsten, 2022; Dewey, 2018). This work-in-progress workshop method contributes to studies of pedagogical games by focusing on how students might develop gaming literacy through board game redesign, offering a novel, hands-on model for engaging students in, and understanding, systemic complexity. We suggest that future research should validate this approach further, in other contexts and with other types of (board) games. Further, future research should investigate this approach as an introduction to the overarching model of gaming literacy in the face of complex problems.
Games Design Frameworks: A Novel Approach for Games Design Pedagogy
Authors: Headleand Christopher , James David
Published: October 2024

The discipline of Games Design has surged in popularity in higher education as a route to industry for aspiring game developers. Notably, at the time of writing 138 UK Universities are now offering game design degrees, and many further education institutions. This growth is not only in volume but also in the diversity of students who enrol in these courses. Young learners, coming from various backgrounds and with differing levels of professional and academic experience, are drawn to games as a field of study. Games disciplines (such as Games Art, Design, and Programming) are often seen as more accessible than their comparative parent disciplines (such as Computer Science). This diversity presents both an opportunity and a challenge for educators: to develop teaching methodologies that not only cater to a wide range of experiences but also effectively prepare students for the creative and technical demands of the games industry. This paper introduces a pioneering design concept utilized in the pedagogy of game design, namely the use of game frameworks. A framework is a structure built in a video games engine, containing a pre-made, playable game experience, which students are taught to build upon and modify. Frameworks abstract and modularise fundamental, complex elements of the game creation process, allowing new learners to quickly become engaged with the iterative process of designing gameplay. It also allows educators to focus on a specific area of interest. For example, a student can focus just on the UI elements of the game for a whole module of study, without needing to have built the entire game first. This allows students to focus on the elements being taught, without introducing a significant amount of non-assessed content just to enable to learning. This position paper discusses our application of this approach, including the process of framework design, supportive assessment, successes and challenges.
Exploring the Relationship Between Challenge and Reward for Game Based Learning
Authors: Benachour Phillip , Zhao Zesen
Published: October 2024

The aim of this research is to investigate how problem-solving challenges affect young people’s motivation for learning computer programming. It explores the relationship between difficulty and reward as part of a game-based learning application and evaluates the effectiveness of the ARCS learning model when teaching primary school children. Research in game-based learning is based, in part, on the study of the impact of games on students' learning motivation, engagement and outcomes. The ARCS model, developed by John Keller in 1987, is a widely recognized model for designing effective instruction that motivates and engages learners. The model is a cognitive psychology-based learning model that consists of four main elements: Attention, Relevance, Confidence, and Satisfaction. A pilot study comprising primary school teachers was conducted to evaluate the effectiveness of the ARCS model. Two experiments were conducted: the first an experimental group based on the design of the game focussing on the player’s experience and evaluation of the difficulty and reward mechanisms. For this group, the game dynamically changes in terms of difficulty and rewards. This is achieved by adjusting the difficulty and rewards through a dynamic player score to maintain player attention, confidence, and satisfaction. The second experiment involved a control group, where the game adopts a traditional linear learning model where difficulty and reward are fixed. For both experiments, data was collected from a feedback questionnaire. The questionnaire was designed to be closely aligned and mapped to the ARCS learning model’s four elements. The scores of the results were based on the Likert scale and t-test to determine the significance of the difference in scores between the experimental and control groups. Results based on data analysis of the user study show that the overall mean score of the experimental group is higher (= 4/5) compared to the control group (= 2.2/5) on all four ARCS elements. Further analysis shows that the most prominent teaching impact is on players’ satisfaction.
Training for Board Game-based Learning: Evaluation Model and Preliminary Results From a National Program in Italy
Authors: Tinterri Andrea , Carena Alessandra , Piccinno Francesco Tommaso , Masini Michele
Published: October 2024

Board Game-Based Learning (bGBL) is a dynamic pedagogical approach that leverages the immersive power and distinctive features of board games to promote active and meaningful learning. However, the use of board games in formal learning environments (such as schools, universities, etc.) is limited, and its use in informal learning contexts (such as cultural associations, after-school, fairs, summer camps, etc.) is often reduced to solely entertainment or engagement functions. The reasons include lack of competencies by teachers and educators and of pedagogical and instructional frameworks in scientific literature. In Italy, a joint effort by the National Sport association (CSI) and the Game Science Research Center has given birth to the first bGBL training course at the national level, based on a two-step structure: the first level (L1) is a short training aimed at all individuals willing to learn how to conduct board game activities in different settings;  the second level (L2) is a more intensive course aimed at L1 trainees willing to learn how to design, implement, and evaluate bGBL activities. Evaluating the impact of such training is paramount to improve its quality, promoting new training opportunities nationwide, and better understand the competencies required for effective bGBL implementation in different settings. The present study focuses on two main aspects: first, presenting the model for evaluating the course, using Kirkpatrick’s Four levels of evaluation as a reference framework, and the related tools that have been developed, including an ex ante-ex post questionnaire based on four dimensions of self-assessment (performance, process, attitudes, and idea of self); second, presenting preliminary results. We aim to identify the professional, motivational and competence profiles of individuals entering L1 courses, information that is instrumental to design the training to fit participants’ needs and expectations. Taken together, this study might provide valuable information on the implementation of bGBL in various educational contexts and inform the design of learning curricula to enhance bGBL competencies.
Immigrants’ condition of expulsability
Authors: Torró Calabuig Aitana
Published: October 2024

This paper examines recent amendments to French and German immigration law aimed at accelerating and enhancing the expulsion of unwanted immigrants of the territory. The main normative changes resulting from these reforms, entailing an unprecedented retraction of legal safeguards against expulsion and significantly exacerbating immigrant’s condition of expulsability, will be presented in comparative terms, without losing sight of the European dimension. Specifically, these reforms shape immigrant’s expulsable presence on the territory through three aspects: an increase on the precariousness of foreigner status, a reduction of the sphere of freedom needed to lead a dignified life and an expansion of exceptionality that obliges us to reconsider our social contract to include a human-rights based approach to immigration.

Digital healthcare, which provides medical services using information and
communication technology (ICT), is emerging as a new paradigm, replacing
traditional methods of healthcare. This study investigates research trends in
digital healthcare through an analysis of studies published in South Korea on
the ethical, legal, and social implications (ELSI) of digital healthcare. To
this end, a total of 471 articles drawn from Korean academic journals in the
humanities, law, and social sciences, were selected as research subjects, and
the current status, characteristics, and research tasks were identified. The
results show that Korean ELSI research on digital healthcare emerged about 20
years ago and has steadily increased, with in-depth analyses of various
sub-topics such as telemedicine, big data, artificial intelligence, wearable
devices, and digital therapeutics. Additionally, notable differences were found
among studies in the three fields examined concerning research purposes,
methods, and major findings. This study comprehensively reviews the research
outcomes of studies in each academic field and proposes future tasks for ELSI
research.
Shared Decision-making: What is Shared? Who Decides? How is the
Decision Made?
Authors: Choi Kyungsuk
Published: October 2024

In this article, I analyze the concept of shared decision-making to explain what
is shared, who decides, how the decision is made, and how shared decision-making
differs from informed consent. Building on the work of Veatch and Charles, I
argue that shared decision-making has two essential features: (a) it helps
patients make decisions while respecting their right to self-determination, and
(b) it maintains the integrity of both physicians and patients. Furthermore,
using the three-talk model and the six steps approach to shared decision-making,
I explicate the concept of “mutual acceptance,” which is central to this
process. Mutual acceptance of the final decision is a two-step process:
physicians first formulate options that align with their own integrity, and then
patients deliberate and choose the options that best suit their needs, wishes,
and constraints. Thus, I argue that mutual acceptance represents physicians’
acceptance of their patients’ final decisions. Furthermore, the closer the
original options are to equipoise, the less psychological burden physicians will
experience regarding the choices their patients make.

This study is aimed at examining the impact of religious commitment on Malay Muslim behavior to select a halal hotel which attitude is considered a mediating variable. The research findings are beneficial for both academicians and practitioners in the domain of Islamic tourism.The study is based on the Theory of Reasoned Action , arguing that religious commitment affects the willingness of Malays to note their intention and dislike the halal hotel selected.A Structural Equation Modeling approach was adopted to analyze the data drawn from the survey of 492 respondents at the Kuala Lumpur International Airport. Respondents who agreed to participate in the survey had to sign the consent form.It was discovered that religious commitment has a significant impact on the attitude as well as the behavioral intention of consumers when the obtained effect sizes are equal to.306 and.443, respectively. On the other hand, the attitude serves as a partial mediating factor with an effect size of.129. The research findings may be useful for hoteliers wishing to develop their marketing strategies to attract Malay Muslim customers who consider the intention to select a halal hotel as well as their attitude.

The article outlines the problems of increasing the photosynthetic activity of winter wheat, depending on the seeding rates and varietal characteristics. Based on the study of scientific literature, the state of knowledge of the issue is shown, data are given on the role of photosynthesis and seeding rates in the formation of wheat grain yield. The results of the formation of grain yields have been studied in detail and covered quite fully. The best seeding rates have been identified that provide the optimal leaf surface area for winter wheat plants. Based on the study of scientific literature, the results of studies on the influence of seeding rates on the formation of the leaf surface, photosynthetic potential and net productivity of photosynthesis are presented. Biological features of varieties, seeding rates and cultivation conditions are factors that affect the size of the photosynthetic apparatus and its intensity. Techniques leading to an improvement in the development of leaf area in crops are the most important means of fighting for a high yield. Thus, studies conducted in the steppe zone of the KBR showed that an increase in the leaf surface area of winter wheat varieties is associated with a change in seeding rates from 4.5 to 6.0 million/ha. The results of the research showed that the maximum leaf surface area of the studied varieties was in the earing phase and varied on average at a maximum seeding rate of 6.0 million/ha from 46.3 to 50.4 thousand m²/ha. Studies have established that with an increase in the sowing rate, the photosynthetic potential (FP) of varieties increases, reaching maximum values in the heading phase. In the winter wheat variety Yuzhanka, FP in the heading phase at a rate of 6.0 million sprouts. seeds per 1 ha amounted to 1.6081 thousand m² ha/days, for the variety Nota - 1.2651 thousand m² ha/days, respectively. As a result of the analysis of the literature, the main patterns of changes in the photosynthetic parameters of winter wheat varieties depending on the seeding rates, development phases and conditions of the natural zone were clarified. The conducted studies have shown that the area of the leaf surface and the duration of its work depend on the plant density, development phases and characteristics of the varieties. Based on a review of domestic and foreign scientific literature, the role of photosynthesis in the formation of crop yields is determined, and the relationship between the photosynthetic potential and assimilation surface and the size of field crop yields is shown. The influence of soil and climatic conditions, temperature and predecessors, mineral fertilizers, water regime and cultivation methods on the photosynthetic activity of agricultural crops was revealed.

The article presents the results of testing nanocomposition electroplating coatings based on chromium for wear resistance and corrosion resistance. The studied nanocomposite coatings were obtained by co-deposition with nanoscale aluminum oxide particles. Nanoscale particles had a spherical shape and dimensions of 10... 100 nm. The production of nanoscale particles with such parameters was achieved by plasma recondensation of the feedstock. Electroplating chromium coatings were applied from a self-regulating chromium plating electrolyte in solid chrome plating modes. In order to ensure high sedimentation resistance of the electrolyte-suspension, nanocomposition coatings were applied under constant exposure to ultrasound at a frequency of 18 kHz. Tribological tests of the samples were carried out on a friction machine according to the "roller – pad" scheme according to GOST 23.224–86. Corrosion tests of the studied coatings were carried out on a laboratory installation by immersion of the studied samples in a saline solution according to GOST 9.308–85. As a result of laboratory tests for wear resistance, it was found that nanocomposite electrolytic coatings based on chromium have a wear resistance 1.5–1.8 times higher than the wear resistance of chromium base coatings and 2.1–2.2 times higher than the wear resistance of steel SHX15. The corrosion resistance of the chromium-based nanocomposition coating is 1.86 times higher than the corrosion resistance of the chromium base coating and 6.86 times higher than the corrosion resistance of 15X steel. Given the high wear resistance and corrosion resistance of chromium-based nanocomposite electroplating coatings, they should be recommended for use in machine-building and repair production as a way to restore worn parts and strengthen new ones.

Damage, injuries and fractures of locomotor apparatus, agricultural, small unproductive, wild animals, are diagnosed in at least 30% of cases of the total number of non-infectious pathologies. In veterinary and humane medicine, complications associated with violation of the integrity of tubular bones have not been eliminated to date. Today, taking into account the various methods of osteosynthesis, where a variety of metal structures, spokes, pins, devices are used, it is definitely important to add biocomposites to the area of intramedullary space at the level of the fracture zone, to accelerate the consolidation process and prevent bacterial contamination. The article presents the hematological parameters of experimental animals (rabbits) using the developed biocompositional osteoplastic material injected into the intramedullary canal, with a simulated fracture followed by osteosynthesis. Samples of general and biochemical analysis of animal blood (n=60) served as the material for research. The purpose of this experiment and research was to evaluate hematological parameters using the developed biocomposite, with confirmation of the absence of undesirable complications of delayed and immediate type on the part of experimental animals. The authors determined, based on a clinical blood test, the absence of hematopoiesis inhibition and inflammatory reactions to a biocomposite consisting of sodium alginate, hydroxyappatite, distilled water, amoxicillin and methyluracil. Thanks to the study of biochemical blood analysis, the absence of intoxication activity of the biocomposite on the hepatobiliary and renal systems of experimental animals was determined. This osteoplastic biocomposite, from the point of view of a group of authors, accelerates the consolidation activity of bone fragments due to antibacterial, osteoconductive and osteoinductive effects.

Authors:   Saratov State University of Genetics, Biotechnology and Engineering named after N. I. Vavilov, Samsonov Evgeny Vyacheslavovich
Published: October 2024

The number of Siberian roe deer (Capreolus pygargus P., 1771) in the Saratov region in the 60-70 years of the last century was several dozen individuals, in 2019 the number was more than 15 thousand individuals. The area characteristic of the Siberian roe deer habitat in the Saratov region is 1,543.18 thousand hectares (15.5% of the total area of the region's hunting grounds). The dominant habitat categories for this species are: "Farmland" – 39.9%, "Forests" – 39.8%, "Young trees and shrubs" – 10.8%, "Floodplain complexes" – 6.4%. The state of the population was assessed according to the following indicators: the dynamics of the number, the density of individuals per unit area characteristic of the habitat of the species, and the ratio of the economically expedient number of the species to the actual one. Growth has been noted in the long-term dynamics of the number. The population growth over the last decade has averaged 17.2%. On 4.1% of the habitat area peculiar to the species, the density of individuals (per unit area) was more than 20 individuals per 1 thousand. ha; by 42.7%, the density was from 10 to 20 individuals per 1 thousand. ha; on 53.2% of the area peculiar to the species, the density was below 10 individuals per 1 thousand hectares. In general, the density of roe deer in the region is 10.3 individuals per thousand hectares of the area suitable for the habitat of the species. For Right–bank areas, these indicators are 12.0, for Left-bank areas - 6.6 individuals per thousand hectares. The percentage ratio of the actual and economically feasible population in only one administrative district of the region (Balakovsky) is close to 100%. This is 2.5% of the total habitat area peculiar to the species. On 13.8% of the habitat area, this indicator ranged from 55 to 86%. In most of the area (83.7%) typical for the habitat of the species, the number does not reach 50% of the economically feasible. In the whole region, the percentage ratio of the actual and economically feasible number for 2019 was 35.7% (the actual number of roe deer is 15,757 individuals, economically feasible – 44,193 individuals). The deficit in economically expedient numbers (the difference between economically expedient and actual) is 28,436 individuals.

The article discusses the dynamics of the transformation of the spatial structure of the location of agricultural production over the period from the beginning of market transformations in the 90s to 2021, and analyzes changes in regional food production over this period. The process of concentration of the main group of regions of the country, which form the basis of the food base of Russia, is revealed. It is concluded that land-intensive industries are shifting and concentrating in areas with available natural and labor resources. On the basis of the analysis carried out, the degree of uniformity in the distribution of crop and livestock production in the context of federal districts was revealed. The results obtained can be used in the development of an agricultural development strategy, taking into account regional characteristics, and in determining the target indicators for the development of agriculture. Solving the problem of the spatial development of agriculture is associated with an integrated approach to the implementation of such fundamental principles as: achieving the country's food security; ensuring the most complete and efficient use of bioclimatic and production potentials, the maximum approximation of the production of one or another type of agricultural product to areas and regions that have, first of all, the most favorable natural conditions; priority of national interests over regional economic interests; a differentiated approach to the main directions and measures of state support for the spatial development of agriculture and rural areas; complex solution of issues of territorial organization of agriculture. Significant regional differences in agriculture and its individual sub-sectors preclude a unified approach to their spatial organization. At the same time, special attention should be paid to such regions as: a few regions with relatively favorable natural and economic conditions for intensive and competitive agriculture; priority and border geostrategic territories; separate depressive and sparsely populated territories, primarily the Non-Chernozem zone; numerous regions of the Far North and terrain equated to them; labor-surplus and densely populated national republics of the North Caucasus. Since in the future the differentiation of regions in the production of certain types of agricultural products will increase to a greater extent than the tendency towards their self-sufficiency, the state should play a key role here.

The article deals with the consumption of milk and dairy products in the Russian Federation; the need for the use of tools and methods of state regulation of the milk market was emphasized in order to ensure food stability in the context of import substitution. The analysis of the balance of resources and use of milk and dairy products showed an increase in the production of imports and stocks. During the study of the current state of the milk market and its consumption, it was found that the production and consumption of milk per capita tends to increase. The level of self-sufficiency in milk both in the Russian Federation and in the context of the regions of the Central Chernozem region is also growing. An increase in consumer prices for milk and dairy products was noted. It was revealed that the development of livestock industries, especially dairy, is influenced by a number of factors associated with limited opportunities to enter export markets due to the presence of strict requirements for veterinary documentation. A disproportion has been found between the growth in the cost of production and processing of agricultural products and retail prices, which will contribute to a slowdown in the growth of the raw materials and processing sector. The effectiveness of the implementation of the State Program in 2020 is quite high, since the agro-industrial complex in general and dairy cattle breeding in particular have demonstrated resistance to the influence of external factors, the possibility of ensuring the country's food security. In dairy cattle breeding, the negative trend in overall milk production has been overcome, which is the result of targeted state support for this sub-sector within the framework of the State Program. In conclusion, effective mechanisms for increasing the volume of milk production and the formation of an investment-attractive sub-sector are proposed.
