The article developed an expression that allows to determine the amplitude values of different harmonics of the magnetizing current at high harmonics caused by the saturation of the magnetic core of the current transformer. Using this expression, it is possible to determine the percentage of the main harmonics obtained for different harmonics, and the determined results allow to accurately set the value of the current (voltage) in the transition state from one range to another to automatically adjust the range of the current transformer.
Geopolitical transformations and their impact on the energy system are closely related to the formation of the modern world order, and the energy factor plays an increasingly important role in international relations. Currently, energy security is regulated not only by the laws of a market economy, but also by geopolitical interests. Recently, it has been observed that subjects of international relations are trying to use the energy and raw materials factor to advance their interests. In the modern world order, fierce competition and the struggle for energy resources have taken a new turn. Leading countries are striving to establish themselves firmly in regions with large reserves of raw materials. Relations in the field of production, transportation and supply of energy to foreign markets are directly related to geopolitical processes. Therefore, under the influence of geopolitical transformations, this form of relationship changes systematically and functionally. The modern international energy system is affected by the forces and factors inherent in the world order, and is becoming increasingly complex. Geopolitical transformations have a significant impact on the international energy regime, creating a new configuration of geopolitical forces. New large consumer centers are emerging in the international arena, and competition between them is growing. The emergence of new centers of power has a significant impact on international energy relations. Energy conflicts between power centers and other actors weaken the foundations of global energy security. At the same time, the lack of effective international legal mechanisms to ensure energy security complicates the energy situation. This article discusses the impact of geopolitical transformations in East Asia on energy security, geopolitical processes in the region, the impact of the geostrategic, geo-economic interests of leading countries on international and regional energy relations, the impact of economic competition and political tension on markets, investment and energy resources of the countries of the region on the total security of the region, the geopolitical situation in the region and the participation of leading states, as well as international and regional political and economic structures. Also highlights problems of energy security in East Asia, the energy situation in the region, current issues of energy in the region, energy policy and cooperation of the countries of the region, the main directions of modern architecture of energy security in East Asia, energy strategies of the countries of the region, the institutional foundations of energy security, the problems facing energy diplomacy of the states of the region, the impact of regional conflicts on energy security and other relevant issues facing today's energy security in the region. It also provides analytical forecasts of the future energy situation in the region and in the international arena. The article concludes with scientific recommendations aimed at ensuring energy security and enhancing the effectiveness of cooperation in the context of geopolitical transformation.
The study discusses some key issues regarding the impact of the COVID-19 pandemic on the international relations, the global economy. According to the author, slackening of economic relation in global economy, the falldown of Gross Domestic Product, has counted against many national economies and for global economy as a whole. In this context, it is also necessary to emphasize that the issue will negatively affect the cultural and humanitarian relations between the countries, which will also affect and slow down the pace of development of international relations after the pandemic. The situation that has developed in the world as a result of a pandemic makes it clear that the emergence of any disease, epidemic, threatens its mass spread among millions of people and not a single country or state is protected from this, and the consequences apply to absolutely all spheres of life of a human being. At present, for many states, along with political and economic problems that need urgent solutions, the construction of hospitals, their equipping and provision of medical personnel, the lack of which is especially acute in the context of the global epidemic, has become especially priority. And, in such conditions, the development of multilateral cooperation is acutely felt, actions together based on the principles of cooperation in solving priority problems. The following tasks are revealed in the article: study of the situation in the world related to the current spread of the coronavirus, the impact of the pandemic on international relations; measures taken by governments in a pandemic conditions and their effectiveness; Uzbekistan's experience in counteracting the pandemia; strengthening regional cooperation; Uzbekistan's initiatives to combat the pandemia. The general situation, connected with the spread of the pandemia is examined. The consideration is given to the measures applied by the countries’ governments in combating the coronavirus pandemia, as well as their effectiveness. The article presents the experience of Uzbekistan in combating a pandemia, initiatives to combat the crisis, as well as strengthening regional cooperation with neighboring countries at the current stage. Currently, only the beginning of regional cooperation between Central Asian states is observed. The study of the issues of spread of coronavirus, and its impact on international relations are not well-defined. Since the pandemic has spread throughout the world, there are a lot of questions for research, not only large-scale, but also local in nature. In the course of the work, the author applied a systematic approach.
In modern abdominal surgery, one of the current areas for research continues to be the improvement of various options for plastic surgery of postoperative hernias. More than 2,100,000 operations for ventral hernia are performed annually in the world, and 42% of them are postoperative hernias. In recent years, there has been a clear trend toward the expanded use of various types of biological meshes in hernioplasty. “A pooled analysis of seven PCSTAR studies for incisional hernias using retromuscular mesh showed a hernia recurrence rate of 5.7%”[1]. The use of standard surgical interventions such as alloplasty in the onlay position does not solve the problem of early postoperative complications: seroma discharge, mesh migration, adhesive disease, high frequency of hernia recurrence, etc. At the same time, hernia repair with local tissue creates the problem of increased intra-abdominal pressure and late complications in the form of recurrent hernias. “An increase in postoperative intra-abdominal pressure leads to multiple organ failure, then abdominal compartment syndrome, and even death.” [2]. Currently, there is no consensus on the surgical approach for giant postoperative abdominal wall hernias, and therefore the need to continue to develop new technologies and improve There is no doubt about the tactics. In world practice, at present, the most relevant studies continue to be studies aimed at studying the morphological and functional aspects of recurrent postoperative ventral hernias; electron microscopy reveals ultrastructural destructive changes in skin cells, aponeurosis and muscles, which indicates morphofunctional insufficiency of abdominal wall tissues; issues of cell engineering are discussed new innovative materials, experimental studies are being carried out on animals testing the biotechnical properties, texture and elasticity of new polymers, research is being conducted on open approaches with division of the posterior component with the release of the transverse abdominis muscle and a retrograde mesh, robotic operations have begun. Modern aspects of the development of domestic healthcare include many measures aimed at improving the results of treatment of patients with postoperative ventral hernias and associated pathological conditions through the introduction of modern principles of intensive care and surgical tactics. The development strategy of New Uzbekistan for 2022-2026 in seven priority areas includes tasks to improve the quality of provision of qualified medical services to the population[3]. The implementation of these tasks, including by optimizing tactical and technical approaches to the choice of hernioplasty method, as well as the development of methods for the prevention of purulent-inflammatory complications in the field of alloplastic material, is one of the current areas of abdominal surgery and medicine in general, due to the high medical and social the significance of this pathology.

As a result of studies conducted around the world to increase the effectiveness of alloplasty for postoperative ventral hernias and reduce the risk of complications in the postoperative period, a number of scientific results were obtained, including: it was determined that patients who underwent reconstruction of the abdominal wall have an increased risk of postoperative respiratory failure, understanding the epidemiology of this complication can improve prevention (the Division of Plastic and Reconstructive Surgery, Department of Surgery, Oregon Health & Science University, USA); It has been proven that the larger the hernia, the higher the risk of early surgical complications, including such as respiratory decompensation, since hernias often increase in size over time, delaying surgery can lead to an increase in the size of the hernia and, therefore, a greater risk of complications (CentreforDigestiveDiseases, KarolinskaUniversityHospital, Stockholm, Sweden); it has been shown that the ratio of the hernia volume to the volume of the abdominal cavity <20% is an independent factor in tension-free closure, which justifies the interest in preoperative volumetry to adapt the tactics of surgical care (Servicedechirurgiegénérale, digestiveetendocrinienne, CHU LyonSud, HospicescivilsdeLyon, France); It has been determined that in patients undergoing elective laparoscopic hernia repair, predictors of mortality are older age and certain concomitant diseases: congestive heart failure, pulmonary circulatory disorders, coagulopathy, liver disease, metastatic cancer, neurological disorders and paralysis (Department of Surgery, College of Medicine, University of Oklahoma, Tulsa , USA); Older age, ascites, preoperative renal and pulmonary insufficiency have been found to be independent predictors of 30-day mortality, and in the presence of these risk factors, conservative treatment should be seriously considered (Department of Surgery, University of Kentucky College of Medicine, Lexington, USA); The American College of Surgeons (ACS) Universal Surgical Risk Calculator has been shown to accurately predict thirty-day outcomes, including major complications: venous thromboembolism, medical morbidity, surgical site infection, unplanned reoperation, mortality, and length of hospital stay (Department of Plastic Surgery, Brown University and Rhode Island Hospital, Providence, USA). At the present time in the world, the most relevant research in surgery continues to be the development of new methods of hernioplasty for large and giant ventral hernias, each of which has its own pros and cons depending on the complexity of implementation, the risk of postoperative complications and relapse, large randomized clinical trials are being conducted, comparing existing methods of traditional hernioplasty with laparoscopic access and robotic surgery, which has become increasingly widespread in the last 10 years, a search is being made for new synthetic and biological materials developed for the production and use of composite meshes that have the necessary strength and the ability to prevent fatal local complications in a contaminated environment. However, despite technical advances in this field, no modern hernia repair method or prosthesis meets all the requirements. One of the key problems is that existing synthetic endoprostheses do not have sufficient elasticity, resistance to infection, high mechanical strength and integrity over a long period of time. Further research into these clinical aspects will undoubtedly improve the current understanding of the capabilities of biocompatible endoprostheses and will make it possible to develop an optimal method for their placement during allohernioplasty. The degree of knowledge of the problem. The current period of development of abdominal surgery is characterized by an emphasis on the problems of the effectiveness of introducing new installation methods and techniques for attaching bioprostheses, options for various suture materials to determine the most promising directions for the development of these technologies [5]. Researchers led by BittnerR.[6] (2019) state that a giant postoperative abdominal wall hernia, the maximum diameter of which exceeds 12 cm or the ratio of the volume of the hernial sac to the abdominal cavity more than 20%, is difficult to treat, with a high recurrence rate and a large number of complications. One of the most challenging problems is that after the hernia contents return to the abdominal cavity, postoperative intra-abdominal pressure will increase, leading to multiple organ failure, then abdominal compartment syndrome (ACS), and even death. There is currently no agreement on the surgical approach for these giant incisional abdominal wall hernias. To prevent recurrences, some articles recommend placing the hernia mesh in the sublayer position and or linings (KirkpatrickAW.)[7]. According to CornetteB.[8], to prevent recurrence, it is recommended to place the hernia mesh in a sublayer or underlay position, and to achieve better mesh expansion, a component separation technique (CST) may be a suitable solution, but with a significant risk of complications and recurrence. JensenKK, et al. believe that truly successful giant hernia repair requires effective bridging or augmentation that will prevent recurrence with an acceptable risk of complications[9]. Another pressing issue in abdominal surgery is that patients with incisional hernias are extremely difficult to treat due to a number of factors including obesity, previous hernia repair, previous mesh placement, domain loss, and other variables.
The approach to patients with incisional hernias has changed significantly over the past 20 years due to both advances in mesh technology and surgical approaches. Key factors for successful outcome include modification of risk factors preoperatively, such as smoking cessation and weight loss, selection of mesh appropriate for the type of hernia and planned mesh location, and wide mesh coverage beyond the hernia defect. New techniques such as transabdominal muscle release and component separation with retrograde mesh placement and robotic approaches to abdominal wall hernia are increasingly being used in these patients[10]. Recent years have seen an increase in the number of biological meshes available for abdominal wall hernia repair. Biological meshes typically consist of materials obtained from humans, pigs, or cattle. The rationale for using biological meshes is that they can act as a scaffold for the growth of natural tissues. In addition, there are absorbable synthetic meshes that have properties similar to those of biological meshes, but with theoretically less risk because they are not derived from animal or human material. The choice of mesh for a ventral hernia depends on many factors, which include both the properties of the mesh and its location, for example, whether it should be placed intraperitoneally, preperitoneally, or retrorectus. BaierKF[11](2021) believes that the guiding principle should be to avoid placing uncoated polypropylene mesh in an intraperitoneal location where it may be in direct contact with internal organs. In addition, the type of hernia defect is another risk factor, such as whether the wound is clean or dirty, and whether the repair is performed with a bridge or abutment. Lightweight or biologic meshes to bridge the defect should be avoided due to increased recurrence rates. Holihan JL [12] (2016), Hodgkinson JD [13] (2018) believe that the principle of anatomical restoration to achieve a reliable, tension-free repair with reinforced mesh reduces the incidence of early postoperative complications and late recurrence of hernia compared with bridging mesh. The analysis of the literature concerning the theoretical aspects and clinical experience of using technologies for improving modern synthetic and biological prostheses that can provide a better plastic effect, as well as methods for preventing recurrence of ventral hernias, indicates that this is one of the priority areas in modern abdominal surgery. An unresolved issue remains the choice of the optimal endoprosthesis, which is highly effective and meets international standards for such properties as biological inertness and mechanical strength, as well as the method of positioning the mesh in relation to the layers of the abdominal wall. Considering that many of the allohernioplasty methods used today are not without drawbacks, the current direction is the development of new methods of repair for giant ventral hernias and methods for the prevention of postoperative complications in conditions of a contaminated wound, with justification of their effectiveness in a clinical experimental study. The connection between the dissertation research and the research plans of the research institution where the dissertation was completed. The dissertation research was carried out within the framework of the research work plan of the State Institution “RSNPMCH named after. acad. V. Vakhidov" under the project AL-422105574 "Development of new biocompatible mesh implants made of composite materials for reconstructive surgery of abdominal and diaphragmatic hernias" (2022-2024).
The purpose of the study is to improve the results of surgical treatment of large and giant postoperative ventral hernias by introducing new laser technologies and improving the tactical and technical aspects of surgical treatment. Objectives of the study: to study the structure of immediate complications after various types of prosthetic plastic surgery; to clarify the influence of obesity factors, primary or repeat hernioplasty on the incidence of immediate and long-term complications; to evaluate the role of the immediate complicated course of the postoperative period in the incidence of long-term complications of hernioplasty; to improve the technical aspects of alloplasty for large and giant postoperative ventral hernias (POVH); to improve the technique of photodynamic therapy (PDT) of the wound surface after prosthetic plastic surgery; to study in an experiment the effectiveness of using the proposed technique of alloplasty and PDT; evaluate the morphological features of the condition of tissues during prosthetic plastic surgery using the proposed method; in a comparative aspect, evaluate the clinical effectiveness of the proposed alloplasty options in the immediate and long-term periods. The object of the study was the results of allohernioplasty in 448 patients with extensive (large) and giant POVH, who were operated on at the surgical department of the 1st clinic of the Samarkand State Medical Institute in the period from 2012 to 2021, as well as experimental animals on which the effectiveness was assessed developed a technique for prosthetic repair of postoperative ventral hernias and applied the technique of photodynamic therapy.
The subject of the study is to analyze the effectiveness of the developed alloplasty of postoperative ventral hernias and intraoperative photodynamic therapy in abdominal surgery in experiments and in the clinic. Research methods. To achieve the goal of the study and solve the assigned problems, general clinical, instrumental, biotechnological, experimental, histomorphological, microbiological and statistical research methods were used. The scientific novelty of the study is as follows: it was established that the need for extensive tissue mobilization and, as a consequence, the intersection of lymphatic capillaries during implantation of the prosthesis in the onlay position, as well as the lack of sufficient resorption function of the hernial sac in the inlay position causes a high risk of the formation of clinically significant seromas; It was determined that with prosthetic hernioplasty, along with the volume of the defect, the type of plastic surgery and the degree of obesity, the most significant predictor of the risk of developing immediate complications is the factor of re-intervention in case of recurrent hernia with the presence of a “dormant infection” hidden in the remaining ligature granulomas or scar tissue; the structure and clinical features of the course of long-term complications of hernioplasty for giant and extensive hernias were clarified, taking into account the results of the immediate postoperative period, as well as the option of fixing the prosthesis, primary or repeated hernioplasty and the degree of obesity; the method of surgery for large hernias of the anterior abdominal wall has been improved, characterized by a combination of factors such as the formation of tension-free prosthetic repair, preservation of local resorptive function to prevent the development of fluid accumulations and reducing the risk of infection; the method of preventing the development or progression of wound infection during alloplasty of ventral hernias has been improved, aimed at enhancing the antibacterial effect and stimulating reparative activity through the photosensitizing and photodynamic effect of low-energy laser radiation; It was determined in an experimental model of prosthetic plastic surgery that the proposed method of fixing the prosthesis in combination with the use of the effect of photodynamic therapy through laser radiation helps to enhance reparative processes with a reduced risk of wound complications; It has been proven that all methods of antiseptic exposure and laser stimulation of the wound surface after prosthetic plastic surgery enhance preventive measures against the development of local infection, but are ineffective in the case of an already developed purulent-inflammatory process against the background of the use of alloplastic material. The practical results of the study are as follows: it has been determined that the implantation of synthetic materials for giant and extensive hernias is accompanied by a significant number of wound complications caused by both the surgical technique itself and the reaction of surrounding tissues to a foreign body, requiring improvement of tactical and technical approaches when performing hernioplasty; it was clarified that scar-degenerative changes in the tissues of the aponeurosis in giant and extensive hernias are a predisposing factor to the occurrence of post-prosthetic hernias, especially when implanting the prosthesis in the “inlay” position and, accordingly, require increasing the efficiency of their fixation and engraftment, as well as reducing the risk of developing local complications; it was determined based on the data of an experimental study that the proposed method of alloplasty for large ventral hernias makes it possible to achieve adequate reconstruction of the anterior abdominal wall, reduce the incidence of infection in the wound, and also use a smaller size of prosthetic material; it was determined that the proposed method of tension-free repair of large hernias of the anterior abdominal wall with strengthening of the aponeurosis with a mesh implant allows maintaining physiology, reducing the number of complications, shortening treatment time and reducing the risk of hernia recurrence; It has been determined that the proposed method for preventing the development or progression of wound infection during alloplasty of ventral hernias can reduce the frequency of suppuration, shorten the treatment time and the likelihood of relapse; It has been proven that the use of the proposed tactical and technical aspects of prosthetic repair for postoperative ventral hernias can reduce the incidence of specific complications, reduce rehabilitation time and the risk of hernia recurrence. Reliability of the research results. The reliability of the results is justified by the use of objective criteria for assessing the condition of patients, modern methods of diagnosis and treatment, the correct application of methodological approaches and sets of statistical analysis, methods for solving the problems discussed in the dissertation are based on modern scientific and practical concepts and approaches to the diagnosis and surgical treatment of patients with giant postoperative hernias. Scientific and practical significance of the research results. The results obtained make a significant contribution to the expansion of irradiation of existing ideas about the structure and clinical features of complications of hernioplasty for giant and extensive ventral hernias by identifying the morphological features of the development of a purulent-inflammatory process against the background of the use of alloplastic material, studying predictors of the risk of developing immediate complications, mechanisms for enhancing reparative processes through the use of an improved method of fixing the prosthesis in together using the effect of photodynamic therapy through laser radiation, which made it possible to enhance the antibacterial effect and improve the wound healing process. The practical significance of the study is that, based on the results obtained, the tactical and technical aspects of prosthetic hernioplasty have been optimized, the features of methods of antiseptic exposure and laser stimulation of the wound surface after prosthetic repair have been revealed, enhancing preventive measures for the development of local infection, and the method of surgery for large anterior abdominal hernias has been improved walls, characterized by a combination of factors such as the formation of tension-free prosthetic plasty, preservation of local resorptive function to prevent the development of fluid accumulations, thereby reducing the risk of developing postoperative complications, reducing the frequency of unsatisfactory results, length of hospitalization and the likelihood of relapse. Implementation of research results. According to the results of a scientific study to optimize the tactical and technical aspects of surgical treatment of large and giant postoperative ventral hernias: the “method for plastic surgery of giant hernias of the anterior abdominal wall” has been improved (invention patent No. IAP 2022 0148 dated April 18, 2022). The proposed method of tension-free repair of large hernias of the anterior abdominal wall with strengthening of the aponeurosis with a mesh implant made it possible to reduce the number of complications, shorten the treatment time and reduce the risk of hernia recurrence; the “method for preventing the progression of infection during alloplasty of infected hernias” has been improved (certificate of the Ministry of Health No. 08-32071 dated October 17, 2022). The proposed method made it possible to reduce the frequency of wound purulent-inflammatory complications and shorten the period of rehabilitation of patients after allohernioplasty; methodological recommendations “Tactical and technical aspects of prosthetic repair for large and giant postoperative ventral hernias” have been developed (certificate of the Ministry of Health No. 08-32071 dated October 17, 2022) . The developed recommendations made it possible to optimize the tactical and technical aspects of allohernioplasty in patients with large and giant postoperative ventral hernias; The scientific results obtained were introduced into the practical activities of healthcare, in particular, in the departments of surgery of the Khorezm and Andijan regional multidisciplinary medical centers, the clinic of the Samarkand State Medical University (certificate of the Ministry of Health No. 08-32071 dated October 17, 2022). Improving the tactical and technical aspects of prosthetic repair for postoperative ventral hernias has made it possible to reduce the incidence of specific immediate complications from 40.9% to 15.6%, to reduce rehabilitation time from 8.6±2.7 to 7.1±1.5 days, and also reduce the likelihood of long-term complications from 11.7% to 3.1%.

Developing the idea of the Arab world or region, Egyptian researchers R. Al-Bustani and F. Fargus, analyzing regional processes, starting with the formation of modern states, do not use the term Middle East, but they write about the Arab world, Arab states, North Africa, East Africa , "The Fertile Crescent" as a part of Iraq, Syria, Lebanon, Israel, Palestine, the Arabian Peninsula. Another Egyptian scholar, M. Muallim, notes that the Middle East is a region from Iran in the east to Libya in the west, and from Turkey in the north to the southern borders of the Arabian Peninsula and in Africa to the southern borders of Sudan. Such a Middle East is a political concept, and, in his opinion, it is better to use the term “Asian-African region”, which includes all the specifics of territories, starting with the geographical location at the junction of Europe, Asia, Africa, and ending with energy resources. Some scientists compare the excesses of the “Arab spring” and its consequences with such powerful historical disasters as the collapse of the Ottoman Empire and the emergence of national Arab entities after the First World War. In the current situation, the diplomacy of Uzbekistan should assist in resolving conflicts and positive political and economic transformation of the Middle East and have a solid analytical foundation. The article pursues a study of the situation in the Middle East in the light of the changes in regimes and changes in the geopolitical configuration of the region. The article also analyzes the features of the formation and implementation of the foreign policy of the Islamic Republic of Iran (IRI) in the Middle East (Iraq, Turkey, the Syrian-Lebanese-Palestinian zone, Egypt, the Persian Gulf countries, Yemen) in the context of the transformation of forms and methods of implementing Washington’s strategy on “systemic containment” Iran. Particular attention is paid to identifying the potential of Iran as one of the leaders in the Middle East region. Therefore, the article widely discusses the main directions of the foreign policy of the countries of the Middle East and gives us assessments of the Middle East situation.

The modern energy system is largely based on the use of fossil fuels, which makes up almost 90% of the global energy consumption structure. Intensive production of raw materials has a negative impact on the environment. This in turn creates environmental problems. The depletion of available reserves of the main energy resources of oil, gas, coal, ore and other minerals will worsen the energy situation in the world. Today, renewable energy interest to many countries due to increased dependence on imported energy, climate change and environmental protection, high rates of economic development and population growth. The widespread use of renewable energy sources will create socially and environmentally clean energy structures. That is why alternative energy technologies - hybrid cars and electric cars, solar, wind, geothermal energy, bioenergy are developing at a high level. This article discusses current trends in renewable energy, alternative energy sectors in Japan and the stages of development of solar energy, features of solar energy, advances in modern technologies for the use of renewable energy sources and the challenges facing renewable energy sources. Also highlights Japan’s new energy policy and strategy, legislation on energy efficiency, programs and strategic plans, changes in the country's energy policy, diversification of energy resources and current problems of energy security. It also analyzes the prospects for the development of renewable energy sources in Japan, new projects in the field of solar energy and mechanisms for their implementation. And also, scientific conclusions were drawn on the analysis of current trends in the development of renewable energy in Japan.

The current state of scientific development of current problems of linguistics, the tasks of lexicology, the general development prospects of the theory of meaning and evaluation require the search for linguistic innovations, a new look at previous problems, and at the same time include current issues. Linguistics has been studied in a comparative way into the orbit of scientific research. The current stage of development of linguistics places the task of researchers to re-examine these issues on the basis of modern methods, one of which is the method of studying language materials as a specific system. This is because language and its layers are integrated with the layers as a whole, including the dictionary itself. Each dictionary is represented by its own layered system, because each word and, accordingly, each concept occupies a certain place in this system, which is determined by its relationship with other words and concepts.
