The quantity of data on web is increasing as the user of the internet grows. Now, Software is capable enough to replace everything that requires human interference or presence. SDLC (Software Defect LifeCycle) is process that is followed in developing the Software, which comprises of rigorous testing. To avoid wasting time and effort on Bugs, Software Bug Prediction has a crucial role in the early phase of development in maintaining and developing the good quality of Software. Bugs are the small section of code which leads to failure of an application. The focus of modern testing and debugging methodologies has switched from 'detecting' to 'predicting' faults in the code. Software Bug Prediction concerns with overall success as early software prediction can improve the quality, reliability, efficiency, reduced cost of Software. The outcomes accomplished were compared with various other different technique and XGBoost technique defeat them for all dataset. Many machine learning algorithm predicts less accuracies and assumes that characteristics for the dataset creates a problem of biasness and High variance. Current technique also does not perform so well on sparse data and possess low execution speed and accuracy. This paper studies and compares the hidden patterns among software attributes that are extracted using a machine learning approach for 4 dataset from NASA JM1, CM1, KC2, and PC3 using multiple machine learning and ensemble classifiers LogisticRegression, DecisionTree, RandomForest, Adaboost and XGBoost.

Deterministic Safety Analysis (DSA) is one of the mandatory requirements conducted for Nuclear Power Plant licensing process, with the aim of ensuring safety compliance with relevant regulatory acceptance criteria. DSA is a technique whereby a set of conservative deterministic rules and requirements are applied for the design and operation of facilities or activities. Computer codes are normally used to assist in performing all required analysis under DSA. To ensure a comprehensive analysis, the conduct of DSA should follow a systematic approach. One of the methodologies proposed is the Standardized and Consolidated Reference Experimental (and Calculated) Database (SCRED) developed by University of Pisa. Based on this methodology, the use of Reference Data Set (RDS) as a pre-requisite reference document for developing input nodalization was proposed. This paper shall describe the application of RDS with the purpose of assessing its effectiveness. Two RDS documents were developed for an Integral Test Facil...

In this paper, we discuss the application of a systematic approach to magnet design to single‐sided magnets [1]. This approach, based on analytical expressions of the spherical harmonic expansion terms for basic magnet blocks allows to compute exact geometry parameters for structures optimized in homogeneity and field strength for a given amount of material. The case of homogeneous fields and a controlled strong gradients are treated separately. This method can be applied to both in situ and ex situ configurations. We present a possible single‐sided structure generating a strong gradient at a remote distance. This structure adopt an axial symmetry and is magnetized along its axis, generating a field along that axis. A prototype of this model has been fabricated and we report its initial performances. This magnet has been integrated with an optimized planar coil for single‐sided excitation and detection. Initial images of thin olive oil layers are also presented.

With the advent of digital radiography, there has been a gradual shift from operators viewing images to find defects to totally automated defect recognition (ADR) systems. This has resulted in reduced operator subjectivity, reduced operator fatigue, and increased productivity. These automated defect recognition solutions are based on reference or non‐reference based approaches or a combination of both. There exists some amount of uncertainty or reluctance to accept automated systems in view of no systematic quantified metrics available on performance of these ADR systems in comparison to human operators. This paper describes the metrics that one could follow to quantify the performance of ADR systems such as detectability for different defect types and sizes, accuracy, false call rate, robustness to various noise levels etc., As it might be difficult to have images with defects of various sizes, shapes, contrast and noise levels, a methodology to generate images with simulated defects with variability’s i...

The purpose of this work is to formulate the general principles of a systematic approach to justify the duration of the components of operational stage as a part of constructed assets life cycle for further development of organizational and technological model of operational suitability of constructed assets during their operation. It is established that measuring works are an integral part of the process of operation and repair work in its composition, which are carried out according to a single schedule of operation of the building, and the frequency and volume of measuring work are correlated with the corresponding indicators of repair work. Increasing the life cycle of constructed assets can be ensured by timely repair work, preventing the decline in serviceability of buildings during their operation. Optimization of repair work is possible by taking into account a set of informational, technological and technical factors influencing the operational suitability of the constructed assets. Without taking into account timely information about the technical condition of the object, their labor costs increase; the use of information system of instrumental monitoring reduces the number of repairs and labor costs during their implementation by obtaining timely information about the technical condition of the object. Organizational, technological and technical indicators of the life cycle of buildings depend on the efficiency of information systems. Detection, prediction of development and correction of damage during operation is an urgent problem related to the need to improve the serviceability of constructed assets, which can be solved by systematically processing reliable information about its technical condition, which will be obtained by instrumental measurements.

Stress theory is a key aspect of industrial management and labor psychology. It focuses on the interaction between the individual and the work environment, exploring the impact of stress on both work productivity and the well-being of employees. Industrial management should consider the impact of stress within the workplace and its consequences for workers and organizations as well. Stress occurs when there is an imbalance between the demands of the environment and the resources available to cope with these demands. This imbalance can result from a variety of factors, including working conditions, organizational changes, personal challenges, and more. The purpose of the report is to study and measure the amount of stress experienced in the transport industry, with a particular focus on the transport company "ZSK-DEVNYA" JSC in order to provide a detailed analysis of the factors impacting employee stress levels. By applying scientific methods and tools, a systematic approach will be developed to gauge the levels of stress within the organization while analyzing the interrelated factors, such as workload, time constraints, social interactions, and other relevant aspects.

Despite many publications devoted to the training of personnel and methods for improving the level of training of engineering and technical personnel of industrial engineering companies, the issue of a systematic approach to assessing the effectiveness of using the scientific potential of an enterprise is still relevant. The need to form a set of measures, develop theoretical foundations, sound conclusions and proposals aimed at developing a fundamental mechanism for intensifying and attracting employees of modern engineering companies to research activities, implies that the management has special automated systems for evaluating the rating of each employee involved in the process of solving problems technical orientation and introduction of the latest science-intensive technologies. For implementation of these systems in large enterprises, it is necessary to develop a kind of methodological platform that will not only algorithmize the entire complex of the process of assessing the scientific activity of performers but will also contribute to more rational planning and carrying out the necessary activities in the scientific and innovative sphere of the company. The article proposes one of the methods for assessing the level of training of scientific personnel, based on the principle of stimulating employees on the part of the enterprise.

Application of solar energy in a portable solar charger is a sustainable solution especially at locations that are far away from the electricity grid. This study presents a systematic approach in modeling and simulation of solar photovoltaic (PV) array with partial shading conditions. Specifically, the partial shading conditions are based on portable solar charger applications that are modular and can be carried anywhere on the top of a backpack. The proposed method is reasonably accurate and very useful as a preliminary study before designing the interconnection of cells within a solar PV module. Using a mannequin to represent a person carrying a portable solar charger on the top of a backpack, eight scenarios of partial shading is considered assuming that the person is facing eight different directions relative to true north. From there, partial shading patterns are applied in MATLAB Simulink modeling and simulation of the photovoltaic array. The results are verified using real outdoor irradiance measurements at Ipoh, Malaysia. In addition, the maximum output power is determined and compared with simulated output power using MATLAB. It was found that the accuracy of the results is in the range of 94.41% to 97.08%. It is envisioned that the results are important in designing and optimizing solar portable charger that are integrated with camping backpack for anyone that is travelling on foot.

In the design engineering analysis of a building structure, it is necessary to take into account its underground part, consisting of a foundation and a soil base as a substructure with various physical and mechanical properties of its constituent layers. In practice, the complexity of building and analyzing the calculation model of the "building + foundation + soil base" system becomes very significant, largely due to the use of dense meshes of volumetric finite elements (FE) of the soil base. Structuring (or analysis of the system in parts) implements a systematic approach to the computational study of the building, its pile foundation and soil base, taking into account elastic and elastic-plastic deformations of structural materials and soil. The purpose of the study was to choose a rational process for the design of the underground part of the building, consisting of a pile foundation and a soil massif. Achieving this purpose provides a significant reduction in the total amount of calculations and savings in estimated time. Calculations of a finite element model of a pile foundation with a soil massif are performed using superelements that provide reasonable transformations of the original (main) design scheme of the building. In the computational study, a comparative-numerical analysis of the stress-strain state of the pile foundation of a building with a soil mass was performed on the basis of the original (main) and transformed design schemes. The proposed transformed design schemes for a pile foundation with a soil foundation can be recommended for engineering design of building objects for various purposes. [ABSTRACT FROM AUTHOR]

PRODUCTION planning ,AUTOMATION ,CONSTRUCTION contractors - Abstract
The article considers the possibility of using a combinatorial approach to automation of construction production calendar planning on a variant basis. The essence of the combinatorial approach to the construction production multivariate automated design consists in generating a complete set of all feasible organizational and technological solutions for the construction works production at each stage of design based on the capabilities of the contractor construction and installation organization, the production conditions, the construction object characteristics, followed by the selection of the best solution according to the specified criteria. The generation of alternative solutions for the works production at each stage of design is carried out using combinatorics methods with a complete set of feasible alternatives generation. If it is possible to select preferred options (clear criteria) at a certain design stage, then such selection can be carried out. If it is impossible to select the best options at a certain stage of design, then all generated alternative options for organizational and technological solutions for the construction production works are transferred to the subsequent stages of design (modeling). Ultimately, the best option choice for the construction process implementation occurs after the completion of the entire complex of stages and tasks of organizational and technological design (modeling), taking into account how each particular solution affects the entire complex of interrelated tasks and stages, which allows for the systematic approach full use in the construction production design (modeling).

In the methodology, the product is considered a food system with several structural levels. For each level, certain characteristics are modeled in the aggregate that forms the quality of the ready-made product. The system includes modeling molecular interactions of raw materials, combinatorics of nutrient composition, structural and functional organization of a food product, and external consumer characteristics. The presented methodology can become a basis for a new emerging direction in food engineering, combining various scientific concepts, technical, computational models, and metric sizes of their objects. The potential of using this model is determined by the wide possibilities of predicting the characteristics and properties of food systems beyond a full-scale experiment's capabilities. With the development of science, the number of levels for modeling can increase with detail in the hierarchy of scales up to quantum. Consequently, the elements of each level of the hierarchy can represent separate food systems or clusters and serve as new logical-dynamic objects-computer modeling systems. [ABSTRACT FROM AUTHOR]

ARCHITECTURAL design ,DESIGN research ,EXPERIMENTAL design - Abstract
Despite fairly unanimous agreement on the goals of design research, there had been concerns in the past years about what some theorists described as a division in research interest. This came along with the emergence of two different streams of design research: one that aims at increasing design understanding and one that focus on improving the design process, changing existing situation. Theorists suggest that changing the current design situation requires not only knowledge of what exists, but also of what would be desirable and how to change the existing situation into the desired. Although, most available theories express the dual goals of design research, see [4], they have not been able to show what changing existing situations actually needs. More recently, however, the division in design research is beginning to change and a new systematic thinking is now emerging. It suggests that changing the current design situation requires more than what is previously thought; it requires its own methodology in which design understanding and design improving are both essential components of systematic theory creation and validation process. This is the goal of this study; it aims to introduce the new systematic approach of design research that is based on the ECC methodology suggested by Bashier (2021). This paper shows how the evaluation-creation cycles (ECCycles) methodology is structured to address the dual goal of design research by systematically combining the processes of theory creation and validation.

Introduction: The aim of the work is to determine the main approaches to typology and risk management in Smart City projects. The relevance is associated with the development of a risk management system – a set of tools that determine the roles of participants in the risk management process, approaches to identifying, assessing and managing risks, monitoring the level of risks. Methods: A systematic approach is the basis of the research methodology. An interdisciplinary approach, analysis of ISO standards and the results of social research allow us to identify theoretical and applied aspects of the topic. Results: The combination of conceptual academic approaches with an analysis of the Smart City experience contributes to the development of new arguments within the framework of the hypothesis: minimizing the risks of Smart City projects depends on a complex of socio-economic and technological factors, and, to a greater extent, on the involvement of citizens in the processes of discussing the concept and managing the city. The tasks of risk management in Smart City projects must be correlated with the goals of sustainable development. This is reflected in the connection of international standards ISO 37120:2018 "Sustainable cities and communities — Indicators for city services and quality of life", ISO 37122:2019 "Sustainable cities and communities — Indicators for smart cities" and ISO 37123:2019 Sustainable cities and communities — Indicators for resilient cities. Discussion: The main risks of creating and developing a Smart City can be combined into several groups: technological, political, risks of human capital, security, inequality, organizational and financial, preservation of social space. The typology of Smart City risks allows to identify the most significant risks, determine their nature, formation factors, and management methods. Conclusions: Based on the Smart City concept and the theory of risks, it is necessary to set a goal – not only to identify the risks of specific Smart City projects and develop separate areas for leveling them but also to create a common risk management system.

Dam-induced displacement causes involuntary resettlement of the affected population to a new site. This new site has to be planned and designed so that the residents can sustain and thrive in the environment physically, socially, and economically. Therefore, a systematic approach has to be devised to formulate a housing proposal that fulfills the aspirations of the affected population. Unorganized and unplanned resettlement leads to irreversible impacts on the lives of the affected population. The affected population must actively participate and give their opinions in the process of layout design, specific community requirements (if any), and the provisions they expect to be provided in the new housing resettlement site. This study is an organized attempt to formulate an effective housing proposal for the Project Affected Population (PAP) of the Parbati Irrigation Project, Rajgarh, Madhya Pradesh. The major aim of this study is to identify the housing needs of the population displaced and prepare an alternate housing proposal for the resettlement of the PAP, ensuring provisions of basic services for the displaced population. This study formulates a conceptual framework to understand the aspirations of project affected population and their specific needs (if any) and incorporate them in designing the housing layout. The inter-relationship matrix formulated in this study is instrumental in establishing a relationship and incorporating physical planning provisions in the housing layouts for the resettled population in all similar cases.

The goal in writing this thesis is to create an online learning system, especially for Citizenship Education subjects, with the development of information systems and also the development of multimedia which helps conventional education systems that occur in class, where students can directly meet face to face to support the learning process so that researchers conduct surveys such as collecting data in the form of questionnaires from several respondents such as students to support the creation of an online learning system for Citizenship Education subjects using the ADDIE method, software used to design e-learning using the PHP and MySQL programming languages, after that the researcher also evaluated the online learning. The result of creating an online learning system for Citizenship Education subjects is to help students in the learning process by e-learning without any time limit, which makes students more effective in the lesson and also makes learning independent so that students/students can evaluate learning. One of the learning models that can be developed is the ADDIE model. This learning model emerged in 1967 and was created by Reiser and Molland. One of ADDIE's functions is to serve as a guideline in building training program tools and infrastructure that are practical, dynamic, and support the training work. This model was chosen because the ADDIE model is often used to describe a systematic approach to instructional development. In addition, the ADDIE model is a general learning model, so it is very appropriate to be developed in classroom learning. When used in education, this process is sequential but interactive, where the evaluation results of each stage can lead to the development of learning in the previous setting. [ABSTRACT FROM AUTHOR]

- Abstract
In this modem age, the use of biometrics is an important aspect in the lives of people in all areas. Iris recognition is now a trustworthy method of personal recognition due to the outstanding requirements for security and reliable types of identification in biometric systems. It is a main and challenging field of study because of its advantages of high precision and non-contact recognition technology. In automatic identification, iris recognition technology plays a vital role. This paper introduces a new concept of optimal security where the proposed system is trained using Convolutional Neural Networks (CNN) incorporated with softmax classifier. The model is trained on a dataset for iris recognition where only a small number of images were trained for each set and showed an enhancement in the results over earlier methods. It focuses on a systematic approach for iris recognition, even when the images have noise, obstructions and various levels of illuminations. Experiments with standard datasets have shown that the put forward approach can attain high performance than competing with other deep learning-based methods. The efficiency gained from iris recognition based on performance evaluation is accurate, achieving a total of 99%. [ABSTRACT FROM AUTHOR]

The article examines the insufficiently studied problem of activating the intellectual potential, which increases the adaptability of economic systems to the ongoing changes, in which it is called upon to play a decisive positive role. High, but insufficiently active intellectual capital does not guarantee high employee productivity. The authors set themselves the goal of the study-to analyze various aspects of this problem and substantiate the mechanisms for its solution. The article shows that the activation of intellectual capital allows it to act as a rotor that brings in other types of capital, together with which it acts as the dominant factor in development. The study made it possible to substantiate, reveal the ways, mechanisms, and tools for activating intellectual capital, adequate to modern needs. Among them are investment in intellectual capital, which allows it to develop and provide added value for the functioning of economic systems; de-globalization of relations, which makes it possible to reduce the outflow of intellectual capital and intensify its use within the country; increasing the presence of intellectual capital on the Internet through increasing digital literacy, digital culture and the formation of digital thinking; state support for the employment of the able-bodied population with high levels of intellectual capital, which increases its active potential; the formation of intellectual attitudes, guidelines of society, supported by material incentives from the state, aimed at increasing the prestige and material incentives of intellectual workers. The article uses the methods of situational, structural, and statistical analysis, which contributed to the study of the existing state of the object and the identification of ways to activate intellectual capital, including the identification of needs in state regulation of emerging problems. When assessing foreign achievements in solving this problem by different countries, a systematic approach was used. The materials of the article are of practical value for government agencies and business structures. The obtained research results are used in practice when developing mechanisms for activating intellectual capital in various industries and the public sector. Their use contributes to the increase in the efficiency of the use of intellectual capital. [ABSTRACT FROM AUTHOR]

The article examines the evolution of the concept of "high-performance workplace". The infrastructure complex of railway transport is a complex production system, in which a number of systemic problems have been formed over a long period of time, characterized by high wear and tear of the track equipment fleet, insufficient funding for its repair and maintenance, as well as low efficiency in the use of production capacities and labor resources. The transition to landfill technologies for enlarged landfills formed on the road network, taking into account the territorial location of neighboring landfills, provides additional opportunities to increase production efficiency, taking into account the uneven volume of repair work over the years within the borders of railways and climatic factors, which ultimately creates the prerequisites for finding new most effective ways to use technical means, materials, energy and labor resources in close relationship and from the point of view of a systematic approach. In modern conditions of constant development, digitalization and complexity of production systems, the role of the human factor is increasing and such basic concepts as "workplace" and "labor resources" are significantly transformed; the process of creating and modeling high-performance jobs as the main driver of effective development of companies is becoming increasingly relevant. The assessment of modern views on the place and role of high-performance workplaces in the organization and management of production is given on the example of the railway track complex, effective tools for their modeling are proposed in order to improve the quality of operational work and the effective use of the resource potential of the railway company.

In this work, the authors solved the problem of inefficient flooding of low-yielding deposits, the share of which in the territory of the object of study is up to 75%. Using calculations based on previously developed and tested formulas, expressions were obtained that allow planning the most optimal placement of wells to increase reservoir coverage and, consequently, increase the oil recovery coefficient. The presented formulas can be used at the facilities of the Volga-Ural oil and gas province, in particular for deposits confined to the carbonate reservoirs of the Verey, Bashkir and Tournai horizons. Generalization of the experience of developing low-yielding deposits using flooding allowed us to obtain results at a high quantitative and qualitative level. In the course of the study, a number of valuable and applied conclusions were obtained, which must be taken into account when implementing a systematic approach to the issue of extraction of residual reserves of liquid hydrocarbons.

Water is closely linked with all living beings and it is the source of all developments in the form of societal, cultural, rituals and religious beliefs. The river Cauvery is the only perennial river in Tamil Nadu and the water level is raised during rainy season. Out of 133 chapters in Thirrukkural, one of the famous Tamil literature, the second chapter itself deals with the importance of water management and the need for the water cycle. All most all the ancient Tamil literatures have evidenced of various water management practices which were carried out to manage the water throughout the year. Several thousand years ago, the olden civilizations were invented to consume the water flowing through the canals and drainages to the maximum extent. Various dynasty were ruled in India before 1000 years onwards and the emperors handled the water management in a systematic approach and managed the floods and droughts in an effective manner. Various structures like canals, dams and water diversion were built by the emperors for the effective utilization of rain water. This paper deals with the effective water management exercises practiced in more than 1000 old Chozha dynasty in Tamil Nadu. [ABSTRACT FROM AUTHOR]

Interventional study design has been adopted widely in design process and research, bringing new insights into design thinking, and innovating new ways of solving design problems through pragmatic and participative approach. However, there is still a lack of studies conducted in intervening design process at earliest stage with systematic approach due to contextual complexity and levels of competencies among designers. In this paper, we develop criteria preference tool for designing project briefs, as a result of analysing 21 designer's preferences in the specific designated task using pre- and post-study. The criteria preference tool provides us vocabularies that help to explain the challenges and priorities, what are influences the formulation of the brief's design direction and what informs the selection and development of the methods.

In the research conducted by Kazakh scientists in the last three decades in relation to agriculture, in most cases, the goal of a comprehensive study of the place and role of multi-sectoral interacting elements in the country's economy and the tasks facing them as a single complex were set only theoretically. Moreover, a multi-sectoral systematic approach to the study of the issues of comprehensive in-depth processing of agricultural raw materials coming from animal husbandry and state regulation of this process was not proposed. With an effective development of beef cattle breeding, the principle of maximum approximation of cattle meat production to areas where the best natural and climatic conditions for pasture maintenance and fattening of beef cattle, as well as sufficient areas of forage land, should become fundamental. An important circumstance in this case is to ensure the sale of manufactured products on favorable conditions for the agricultural producer. The authors consider the system approach to the consideration of these branches to be the main methodological approach, which received its justification and development at the beginning of the twentieth century, and which is today the most common direction of the methodology of scientific cognition in comparison with the same analytical method. It includes a set of elements, the combination of which is interpreted by researchers depending on their vision of the object of their research. This determines the need to systematize them in relation to the object under consideration. Authors propose to divide the well-known properties of systems into several categories – structural, qualitative and dynamic characteristics of the system, methodological approaches to the study of systems and the most characteristic techniques and methods of research.

The authors consider digital engineering and reengineering technologies for information support of the lifecycle of high- tech products. An integrated and systematic approach was used, the constant change in the conceptual apparatus associated with the lifecycle management system was considered. Examples of formation of models of a digital shipyard, ships and infocommunication platforms are given. It is concluded that development of digital engineering and reengineering allowed us to concentrate efforts to overcome the complexity of a new development and make the bulk of changes at the initial stages of design and development works. There has been a change in the model of R&D financing, there is a concentration of financing in the initial phase of the project. Digital support for the production of each sample of high-tech products makes it possible to form a "digital" one; at the operational stage, digital engineering provides accounting and control of the actual technical characteristics of a real sample and formation of a "digital twin of an operated sample of high-tech products". This ensures the continuity of the transformation of the "digital twin" from "design" at the research stage to "operational" one during operation, which creates opportunities for digital modeling and forecasting of the lifecycle of high-tech products. Introduction of modern technologies for information support of the lifecycle of high-tech products will significantly reduce the time of works and reduce costs for all stages of the product lifecycle, provide effective service, which will undoubtedly increase the competitive advantages of industrial enterprises.

The possibility of obtaining structural and thermal insulation foam concrete of non-autoclave hardening with improved construction and technical characteristics for the device of a thermal insulation layer in the construction of road pavement due to three-dimensional dispersed reinforcement with polypropylene fiber is theoretically justified and experimentally confirmed. Based on the results of studies of the influence of technological factors on the properties of foam concrete, the optimal content (up to 0.25% of the cement weight) and the length (12 mm) of reinforcing polypropylene fibers were established, which allows you to obtain high strength indicators of dispersed-reinforced cement stone for bending (an increase of 12-20%) and compression (an increase of 6-12%) compared to non-reinforced cement stone of non-autoclaved foam concrete. The analysis of the process of structure formation of dispersed reinforced foam concrete from the standpoint of a systematic approach based on multifactorial polynomial models of the influence of the ratio of filler and binder, as well as the number of dispersed reinforcing fibers, which is determined by the optimal distribution conditions of solid and gas phases, as well as reinforcement of adjacent interstitial partitions of foam concrete, linking them into one associate, which ensures the joint work of the material under various external influences. A method has been developed to increase the durability of the road surface and eliminate the influence of the frost heaving effect on the quality of the road surface by introducing the necessary amount of an effective thermal insulation layer into the construction of the road surface. The analysis of the regularity of the heat transfer process in the soil mass of the roadbed and multilayer road clothing is carried out. Based on the conducted analysis the values of the necessary resistance to heat transfer of road clothing for the natural-climatic regions of the country are established and a method for calculating the value of the thermal insulation (frost-proof) layer of road clothing is proposed. A method has been developed for calculating the value of the thermal insulation layer using monolithic fibropen concrete and a nomogram to determine the required value of the thermal insulation layer made of monolithic non-autoclaved structural and thermal insulation fibropen concrete of classes D600- D1000.

Agile is a method that moves quickly, lightly, and approachable in developing a software process. The primary goal of agile methodology is to produce high-quality software in a quicker time. It is using this methodology for developing the Academic Resource in a system provided by software for maintaining academic and financial records of data efficiently and conveniently. The administration of any academic association must make records of students registered and the staff of the university on paper and keep them safe, which is a tedious task due to the increase in manual work that reduced the utilization of the efficiency of staff. This paper describes a systematic approach to developing a user-friendly, flexible, and easy-to-maintain environment for academic resources using agile's extreme programming. The execution of the different tasks to develop the system is used to widen the horizons in Agile Methodologies step by step. [ABSTRACT FROM AUTHOR]

Solving the problem of ensuring the protection of confidential information when negotiating in an office space is important. It is proposed to implement a unified systematic approach to assessing the security of information based on the measurements and the formation of control actions on the elements of the information security system. A methodology has been developed for constructing a research complex for monitoring the security characteristics of corporate information, which provided the creation of software and hardware complex "Means of protecting information from leakage through technical channels." A mockup of this hardware and software complex has been assembled, special software has been developed that allows to study the process of information leakage through technical channels and to optimize the characteristics of the confidential information protection system. The concept of constructing an individual trajectory for training complex operators and information security specialists is presented. [ABSTRACT FROM AUTHOR]
