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.
This dissertation research to a certain extent serves to fulfill the tasks approved by the Decree of the President of the Republic of Uzbekistan “On comprehensive measures to radically improve the healthcare system of the Republic of Uzbekistan” No. UP-5590 dated December 17, 2018, the Resolutions of the President of the Republic of Uzbekistan “On measures to transform the surgical service, improving the quality and expanding the scale of surgical operations in the regions" for No. PP-5254 dated October 4, 2021 and "On additional measures to ensure public health by further increasing the efficiency of medical prevention work" for No. PP-4891 dated November 12, 2020, and as well as other regulatory documents adopted in this area.

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 aim of the study is to development of an algorithm for managing pregnancy and childbirth by studying the functional state of the mother-placenta-fetus system in pregnant women who have undergone COVID-19 in different trimesters of pregnancy.
The object of the study was 105 pregnant women who, were treated at the Samarkand Regional Perinatal Center and a specialized maternity center for pregnant women with COVID-19
Тhe scientific novelty of the research consists of the followings: for the first time in pregnant women infected with COVID-19, a relationship was established between the course of pregnancy, childbirth, the postpartum period and the development of complications depending on the trimester and severity of the disease; a direct correlation has been established between the state of the vessels of the mother-placenta-fetus system (resistance and pulsation indices, Endothelin-1 indicators), disorders in the hemostasis system (D-dimer, platelet aggregation) and the clinical course of the disease in pregnant women who underwent COVID-19; it has been established for the first time that the developed scale for assessing risk factors for non-developing pregnancy in women infected with COVID-19 (age, BMI, obstetric history, gestation period, hemostasis system status, endothelial function and severity of the disease) can serve as a prognostic marker of the degree of risk of pregnancy complications; it was proved for the first time that the choice of effective therapy for restoring hemodynamics in the mother-placenta-fetus system, in women who underwent COVID-19 at different stages of pregnancy, leads to a decrease in the number of thrombophilic complications.
Implementation of the research results. The results of the scientific research were introduced into the practical activities of the Samarkand Regional Perinatal Center by Order No. 128/1 of 01.09.2022 and the Samarkand City Maternity Complex No. 1 by order No. 58/1 of 03.10.2022. In pregnant women who underwent COVID-19 at different periods of pregnancy, changes in the mother-placenta-fetus system were determined using simple and effective research methods, such as ultrasound and Dopplerography, and this saved 53,000 soums; obstetricians and gynecologists, as well as neonatologists and therapists, are needed to diagnose signs of complications in the echocartin, that is, it has been proven that there is no need for other highly qualified specialists for this, due to the lack of need to train new personnel, state budget funds have been saved. With early detection of disorders in the hemostasis system in pregnant women with COVID-19: the period of stay of patients in the hospital was reduced from 10.5 days to 7.5 days and the number of hospital bed days was reduced; due to the reduction of the period of stay in the hospital for several days, the number of necessary drugs was reduced (on average, drugs are used for 1 day in the amount of 130,000 soums). Examination of pregnant women infected with viral diseases using simple and effective research methods such as ultrasound and Dopplerography served to save 85,000 soums: in the early stages up to 16 (10-11 weeks. - fetometry), 19-21, 32-34, 38-40 weeks of pregnancy; due to the absence of the need to use other research methods, it was possible to reduce costs by 23.5%; early detection of changes in the hemostasis system and endothelial dysfunction using fast, budgetary and effective research methods, contributed to the prevention of possible pregnancy complications, as well as the absence of the need to use long-term and expensive research methods, and this saved 106 000 soums: the coagulogram was checked in 105 (100%) patients, time was saved and efficiency was increased; endothelin-1 was also determined in 105 (100%) patients, efficiency was increased by 78.6%.
Improving the functionality of blood circulation in the uteroplacental and fetal-placental systems, a comprehensive analysis of possible complications during pregnancy and childbirth in women who have had viral infections, improving diagnostic, preventive and prognostic measures for managing pregnancy and childbirth contributed to the birth of live, full-term and healthy newborns in women who experienced COVID-19 during pregnancy, as well as a decrease in maternal mortality and perinatal mortality, 43% of women underwent rehabilitation in the postpartum period, 23.8% of women who underwent severe COVID-19 improved their quality of life.
To introduce scientific novelty on the topic “The impact of COVID-19 on the state of hemodynamics in the mother-placenta-fetus system in pregnant women”, a letter was sent to the Ministry of Health from Samarkand State Medical University on November 9, 2022 under No. 4295 (Conclusion of the Ministry of Health No. 8 n-z / 679 of December 15, 2022).

The following issues are analyzed in this scientific article: the significance and historical role of establishing diplomatic relations between the Republic of Uzbekistan and Japan. The huge role of ratification of the strategic partnership agreement between two countries is also shown. The peculiar specifics of the political system of Japan, including the nature, structure and basic functions of the parliament and the procedure for holding parliamentary elections, the place and role of the emperor’s institution in the political system, as well as the cabinet of ministers, are examined. The article considers the basis of the principle of forming the Cabinet of ministers, its role in the process of reforming the political system of society, the features of the political system, in particular the formation of a multi-party system, the reasons for success as a dominant party - the Liberal Democratic Party of the country, the role of the LDP in the process of modernization of the Japanese political system, the role of the Cabinet of ministersin the political system of society, the activities of the Japanese government led by Sh.Abe in the process of updating political system, the government’s program for the development of the country's economy, as well as the specifics of the practical implementation of this program, the activities of the parliament and the cabinet to amend the Constitution of the country, in particular, on articles 1, 4, 7, 9, 41 of the Constitution. Particular attention is paid to the processes of amending Article 9 of the Constitution, which deals with the issue of legal updating of the status of the Japanese armed forces, and on the basis of these changes will complete the "idea of creating" a normal Japanese army. The cabinet’s aspirations to expand the powers of the government by improving the legal norms of the Constitution, in particular by adding a special chapter 9 to the main law, are also considered. The article also shows the prospects for the development of the political system of Japan, where in particular the main attention is paid to the role and importance of accelerated economic development in the process of improving the political system. In addition, the influence of national values and traditions of Japanese society on the positive development of the political system is examined. At the end of the scientific article, conclusions are drawn about the political and legal conditions that are created by the desire of the Japanese government for the development of the political system.

The aim of the research work is determination of the prospects for the use of a domestic agent for the prevention of adhesion formation in thoraco-abdominal surgery on the basis of experimental and morphological studies.
Research objectives were white outbred rats in the amount of 62 individuals, in two experimental studies on the abdominal and pleural cavities, in each series of experiments the studies were carried out in 2 comparative groups, control and main. Experiments on the formation of adhesions in the abdominal and pleural cavities were carried out on the basis of the Republican Specialized Scientific and Practical Medical Center of Surgery named after acad. V.Vakhidov in the Department of Experimental Surgery for the period from 2019 to 2020.
The scientific novelty of the research consists of the followings: it is proved according to the data of experimental research that when modeling the adhesion process in the abdominal cavity, the local application of an anti-adhesion coating made of cellulose derivatives reduces the processes of adhesiogenesis and the development of changes in architectonics, bends and narrowings of the intestinal lumen; it was found in an experimental study that when modeling the adhesion process in the chest cavity, the local use of an anti-adhesion implant provides a significant decrease in the risk of adhesiogenesis in the form of the formation of coarse adhesions or planar adhesions; it was determined that when blood serum was applied over a powder implant, the quality of adhesion and the uniformity of its distribution on the surface of the experimental defect of the peritoneum or lung did not change, but, in contrast to activation by blood (to ensure a hemostatic effect), it was not accompanied by the development of cellular inflammation due to the resorption of thrombotic masses; it was found that the formation of a gel film over the area of damage to the peritoneum in the absence of cellular elements of blood makes it possible to achieve biodegradation of the coating without a pronounced cellular-inflammatory reaction, providing cicatricial replacement of defects with a significant reduction in the risk of developing a massive adhesive process; the morphostructural features of the formation of the adhesive process when using an anti-adhesive coating, characterized by regression in the dynamics of the number of connective tissue cells of the inflammatory infiltrate with scarring of the defect zone without the development of adhesive conglomerates with the surrounding tissues, have been determined.
Introduction of the research results. According to the results of a scientific study on a comparative analysis of the use of a domestic agent for the prevention of adhesion formation in thoraco-abdominal surgery: methodological recommendations were developed: "New technologies for the prevention of adhesions in thoraco-abdominal surgery" (certificate of the Ministry of Health No. 08-09/10055 of August 12, 2021). The proposed recommendations for performing surgical interventions on the organs of the abdominal and thoracic cavities will allow for sparing local hemostasis, as well as prevent the formation of a coarse adhesive process in the abdominal cavity.
The obtained scientific results on a comparative analysis of the use of the domestic remedy for the prevention of adhesion formation in thoraco-abdominal surgery have been introduced into the practical activities of health care, including in the Republican Specialized Scientific and Practical Medical Center for Surgery named after V.I. Academician V. Vakhidov, surgical departments of the clinics of the Andijan and Samarkand State Medical Institutes (certificate of the Ministry of Health No. 08-09/10055 of August 12, 2021). Based on the proposed results of experimental studies, it was shown that the use of an anti-adhesive coating made of cellulose derivatives made it possible to reduce the risk of adhesion formation from 60% to 20%, bowel deformation without manifestations of obstruction from 33.3% to 13.3% and the possibility of acute adhesive intestinal obstruction from 6.7% to 0%.
Structure and scope of the dissertation. The dissertation consists of an introduction, four chapters, conclusions, practical recommendations and a list of cited literature. The volume of work is 113 pages.
Topicality and demand of the theme of dissertation. In world practice of informatization, systems of electronic document interchange (EDIS) arc considered and introduced last years not only as systems for automation of manage processes but also as high-grade platforms for creation of uniform information field, so borders of their use, certainly, expands and scientists of the world raises interest to them. In researches of leading scientists of infocommunication technologies the demand of problems of authentic gathering, transfer, analysis, coding of information during formation of office-work documents is allocated for getting of effective technologies raising mobility and productivity of EDIS.
Complex measures undertaken by the Government of Republic of Uzbekistan on development of systems of region-territorial automated management and to creation of uniform information field arc directed on wide introduction of information systems, EDIS, databases (DB) on the basis of modern information-communication technologies. In this connection, working out of new methods to intelligent processing of information resources used for improvement of data transfer quality, allowing effectively to find out and correct errors in structure of electronic document interchange with least material and time expenses, differs a special urgency and, at the same time, remains the unresolved theoretical and applied problem having important economic value.
Requirements to information resources and streams of data transmission as the important factor of efficiency and quality of EDIS functioning arc expressed in providing of stability, integrity, safety and authenticity of the information. One of important among factors is the criterion of authenticity of the information, caused by distortion of transferred messages in infocommunication networks because of failures and refusals of means, any handicaps in communication channels, errors of operators, scanning and recognition systems.
Hence, construction of effective systems to control of information authenticity during transfer and processing represents special scientific interest as priority technology of data processing, characteristic for conditions of automated management and electronic document interchange at the enterprises and organizations.
For existing methods, despite of providing the high level of information transfer authenticity, some unsolved questions is typical, and as basic of them it is possible to allocate the following: at development technologies of electronic documents interchange in structure of modern data transfer packages the significant volume of resource is spent for headings, at the same time the most part of information in headings remains constant from package to package during stream of transfer of the whole frame (redundancy of the information arising at it and mechanisms to provide reliability of deliveries consisting, basically, in sending the appropriate message and repeated transfer of packages, - result to additional time and material expenses while errors detection and elimination); code and hardware methods of information transfer control arc focused, mainly, on elimination the transposition mistakes in managing fields of packages; however, at data transfer there arc also distortions in information fields, which frequently reveal as multiple text mistakes.
In this relation, the decision of tasks for providing of information transfer authenticity is reasonable to consider in two aspects.
Solutions of the first type tasks should taken into account errors of the man-operator, scanning and other devices intended for input of the information. These kinds of mistakes make greatest volume of distortions in text and arise at Applied and Representation levels of OSI model (Open System Interconnection reference model).
Solutions of second type tasks, devoted to control of the information reliability, take into consideration the probability of distortions which occur at stages of Transport, Network, Physical and Line of model OSI.
Demand of the dissertation is characterized by the fact that introduction of a wide range of IP-enabled technologies in electronic document interchange is connected to requiring close attention tasks of detection and correction of errors during preparation and processing of documents.
This research work is focused on providing realization of laws of the Republic of Uzbekistan «On informatization», «On electronic digital signature», «On electronic document», «On electronic commerce», «On electronic payments», Decree of the Cabinet of Ministers of the Republic of Uzbekistan № 126 on 05.04.2011 «About measures on installation and use of a single secured e-mail and system of electronic document interchange in the executive office of cabinet of ministers, bodies of government and economic governance, local government».
Following that, the solution of listed tasks requires carrying out the special researches and development connected to creation of methods and algorithms, capable to control the information authenticity in structure of data transfer packages at the expense of use the enclosed redundancy, and able to function in transport environment, eliminating existing lacks. This fact causes necessity of allocation of a special class algorithms for providing of information authenticity on the basis of new type of PR-rcdundancy (property redundancy), defined by depending on properties of processed object.
Purpose of research is development ol constructive methods, models, algorithms and systems of information authenticity control during transfer and processing of the data on the basis of mechanisms used PR-rcdundancy of various nature, and software and algorithmic realization of results for developing technologies of electronic document interchange.
