The article analyzes the functions of the Border Guard Service of Ukraine and its information systems. It is determined that the modernization of the components of the integrated information system causes a violation of the existing system of cyber defense. The analysis of existing approaches to ensuring the protection of information in information systems has shown a sufficiently deep study of research separately for each information system. However, unexperienced features of the interaction of these systems remain, in particular, with the modernization of certain information systems in terms of providing cyber defense in general. The process of modernization of information systems is carried out according to individual components of the system or complex and requires their coordination in the process of joint operation. The article gives the justification of modernization strategies according to the groups of criteria: the level of cyber security, the peculiarities of the functioning of information systems. It is noted that the value of the probability of violating the properties of the information resource varies over the entire period of modernization. Therefore, to choose the strategy of modernization at the value of probability at any time is not correct. It is necessary to take into account the general tendency of the function of changing this probability. The most expedient is the distribution of this group of criteria into three components of the criteria for the level of cyber security: the normative - the criterion in which the current value of the probability of violating cybersecurity does not exceed the given; average - the criterion for which the average probability of a violation of cybersecurity does not exceed the prescribed; weighted - a criterion for which the average weighted probability of cybersecurity violation will not exceed the given. The article presents functional dependencies for determining the probability of cyber security violations for each of the groups. As a result of the study, it was determined that the priority indicator of the effectiveness of the process of modernizing the information systems of the border agency is the maximum value of the probability of violating the properties of information in the process of modernization

Properties Of Information

Some of agriculture-food sector information systems are characterised by a high complexity and a large size. There are often many alternative solutions or technologies (implementation methods) and more then one possible way or approach to an information system design. Individual alternatives could considerably differ by their properties, e.g. costs of design of initial functionality, development and operational costs, run-time costs and technical parameters of the resulting information system (e.g. the access time). Unfortunately, existing metrics for quantification of this task usually do not deliver precise results but a rough estimate depending on many variable conditions. The paper will outline typical implementation methods and show approaches to assessment and comparison of certain types of properties of information systems for a computer support for management of large data systems, which use relational database. Authors presented part of these results also at the Agrarian Perspectives conference 2004 in the Applied Informatics session (Vrana I., Vr&aacute;na J. 2004).

Financial information system is an information system that provides information to individuals or groups of people, both inside and outside the company that contains financial problems and information about the flow of money for users in the company. Financial information systems are used to solve financial problems in a company, by meeting three financial principles: fast, safe, and inexpensive.Quick principle, the intention is that financial information systems must be able to provide the required data on time and can meet the needs. The Safe Principle means that the financial information system must be prepared with consideration of internal controls so that company assets are maintained. The Principle of Inexpensive, the intention is that the cost of implementing a financial information system must be reduced so that it is relatively inexpensive.Therefore we need technology media that can solve financial problems, and produce financial information to related parties quickly, safely and cheaply. One example of developing information technology today is computer technology and internet. Starting from financial problems and technological advances, the authors make a website-based financial management application to facilitate the parties that perform financial management and supervision.Method of development application program is used Waterfall method, with the following stages: Software Requirement Analysis, Software Design, Program Code Making, Testing, Support, Maintenance.

Management Information

The distinctive quality of the new social structure is that information becomes the only factor of production. In today's organizations, public administrators are directly responsible for applying information to administrative processes. In addition to his managerial responsibilities, a knowledge based organization requires every employee to take responsibility for achieving efficiency. This has increased the importance of information systems in the decision-making process. Information systems consist of computer and communication technology, data base management and model management and include activity processing system, management information system, decision support systems, senior management information system, expert systems and office automation systems. Information systems in the health sector aim at the management and provision of preventive and curative health services. The use of information systems in healthcare has the benefits of increasing service quality, shortening treatment processes, maximizing efficiency of the time, labour and medical devices. The use of information systems for clinical decision making and reducing medical errors in the healthcare industry dates back to the 1960s. Clinical information systems involve processing, storing and re-accessing information that supports patient care in a hospital. Clinical information systems are systems that are directly or indirectly related to patient care. These systems include electronic health/patient records, clinical decision support systems, nurse information systems, patient tracking systems, tele-medicine, case mix and smart card applications. Diagnosis-treatment systems are information-based systems used in the diagnosis and treatment of diseases. It consists of laboratory information systems, picture archiving and communication system, pharmacy information system, radiology information system, nuclear medicine information system. This study aims to evaluate the effectiveness of health information system applications in Turkey. The first part of the study focuses on the concept of information systems and the types of information systems in organization structures. In the second part, clinical information systems and applications for diagnosis-treatment systems in Turkey are examined. Finally, the study evaluates applications in the health sector qualitatively from the new organizational structure, which is formed by information systems.

Interface Parameters

Рассматривается проблема выбора оптимальных параметров интерфейса в информационных системах с целью его персонализации под предпочтения пользователя и возможности его оборудования. В настоящее время для ее решения используется алгоритмическое обеспечение и статистическая обработка предпочтений пользователей, что не обеспечивает достаточной гибкости и точности. Поэтому в данной работе предлагается применение разработанного метода адаптации параметров интерфейса, основанного на анализе и обработке пользовательской информации с помощью нейронных сетей. Научная новизна метода заключается в автоматизации сбора, анализа данных и настройки интерфейса за счет использования и интеграции нейронных сетей в информационную систему. Рассмотрена практическая реализация предлагаемого метода на Python. Экспертная оценка адаптивности интерфейса тестовой информационной системы после внедрения разработанного метода показала его перспективность и эффективность. Разработанный метод показывает лучшую точность и низкую сложность программной реализации относительно классического алгоритмического подхода. Полученные результаты могут использоваться для автоматизации процесса выбора компонентов интерфейса различных информационных систем. Дальнейшие исследования заключаются в развитии и интеграции разработанного метода в рамках фреймворка адаптации информационных систем Here we consider the problem of choosing the optimal parameters of the interface in information systems with the aim of personalizing it for the preferences of the user and the capabilities of his equipment. Currently, algorithmic support and statistical processing of user preferences are used to solve it, which does not provide sufficient flexibility and accuracy. Therefore, in this work, we propose the application of the developed method for adapting interface parameters based on the analysis and processing of user information using neural networks. The scientific novelty of the method is to automate the collection, analysis of data and interface settings through the use and integration of neural networks in the information system. We consider the practical implementation of the proposed method in Python. An expert assessment of the adaptability of the interface of the test information system after the implementation of the developed method showed its availability and efficiency. The developed method shows the best accuracy and low complexity of software implementation relative to the classical algorithmic approach. The results obtained can be used to automate the selection of interface components for various information systems. Further research consists in the development and integration of the developed method within the framework of the information systems adaptation framework

Interval Valued

As a further extension of the fuzzy set and the intuitive fuzzy set, the interval-valued intuitive fuzzy set (IIFS) is a more effective tool to deal with uncertain problems. However, the classical rough set is based on the equivalence relation, which do not apply to the IIFS. In this paper, we combine the IIFS with the ordered information system to obtain the interval-valued intuitive fuzzy ordered information system (IIFOIS). On this basis, three types of multiple granulation rough set models based on the dominance relation are established to effectively overcome the limitation mentioned above, which belongs to the interdisciplinary subject of information theory in mathematics and pattern recognition. First, for an IIFOIS, we put forward a multiple granulation rough set (MGRS) model from two completely symmetry positions, which are optimistic and pessimistic, respectively. Furthermore, we discuss the approximation representation and a few essential characteristics for the target concept, besides several significant rough measures about two kinds of MGRS symmetry models are discussed. Furthermore, a more general MGRS model named the generalized MGRS (GMGRS) model is proposed in an IIFOIS, and some important properties and rough measures are also investigated. Finally, the relationships and differences between the single granulation rough set and the three types of MGRS are discussed carefully by comparing the rough measures between them in an IIFOIS. In order to better utilize the theory to realistic problems, an actual case shows the methods of MGRS models in an IIFOIS is given in this paper.
