The article analyzes the current state of the methods for assessing the software of complexes of automation of fire control of artillery systems supplied to the artillery units of the Ground Forces of the Armed Forces of Ukraine. The actual problem of verification and certification of the developed samples of special software of such complexes is determined, which consists in the absence of established assessment procedures, a large subjective component in the existing methods for assessing software, the inconsistency of their norms in accordance with state and international standards. In the proposed conceptual model for assessing the quality of software, new metrics have been defined that will characterize special software that ensures the functioning of complexes of fire control automation systems for artillery subunits when they perform fire engagement tasks and which reflects the peculiarity of the use of artillery systems. To assess the proposed new metrics, the elements of their assessment and the mathematical apparatus for carrying out calculations are determined and substantiated. To determine the magnitude of the influence of indicators on the overall quality of software, a new approach is proposed, which consists in applying the method of analyzing hierarchies when determining the priority of indicators of elements, metrics, criteria and factors at each level of the hierarchy. The use of multicriteria analysis of the hierarchy analysis method ensures that the subjectivity of experts is avoided when assessing the quality of special software, it makes it possible to identify bottlenecks in the developed tactical and technical requirements for the software of the indicated complexes of automation tools for artillery systems and takes into account the mutual influence of indicators on the overall quality. A certain improved methodology, which more fully covers the software assessment process, will in the future be the basis for creating a quality assurance system for software of automation systems and forming a tool for their certification.

Usually, planning a software testing requires solving the basic dilemma: how to provide quality of testing and spend optimal amount of resources. Typically, resources include components such as personnel, software, technical equipment, time, consumables and others. The Armed Forces of Ukraine have the same problems in planning and testing of programs that are expected to be used in the interests of troops and arms command and control. Testing can be performed by manual method and computer-aided method. The computer-aided method is faster but has its drawbacks. In particular, this method requires the development and then verification of a special program that will be involved in testing. In addition, this program may not detect certain problems that a person can notice. Therefore, the authors of the article propose to use the method of manual testing. It is proposed to apply a rational approach for reducing the time for planning and testing using this method. It refers to a significant reduction in the range of input values which will be checked. This approach provides a high quality testing program at the same time. The approach is based on the fact that the range (or list) of all possible values of each input variable is divided into several groups (equivalence classes). The separation is carried out by the principle that each equivalence class includes such input values, which will give the similar results after processing them by program. This approach is widely used by experts in the field of testing. It also meets the standards requirements applicable in Ukraine. There are two general classes of equivalence: accepted values and nonaccepted values. Each of them is divided into more specific ones. The separation is done leaning upon knowledge, skills and predictions of a specialist who is planning the testing. This article provides an example of dividing the input values of four variables into equivalence classes. The approach proposed by the authors of the publication allows to perform software testing faster and more rationally. It is assumed that such a method should be used during testing software that is intended to be used in the interests of the Armed Forces of Ukraine.

Purpose The purpose of this paper is to study the microbiological quality of raw milk delivered by 17 vending machines (VM) owned by different Slovenian milk producers. Design/methodology/approach For the determination of hygiene-technical conditions of VM, an observation list that included criteria for estimation of hygiene-technical suitability was made. A total of 51 milk samples were collected in three different seasons. The swabs and the cleaning liquid (eluates) of dispensing nozzles and chambers were also sampled. The main groups of microorganisms were determined by colony count technique according to international standards in all collected samples. Findings The aerobic colony count was higher than 100,000 CFU/mL in 20 (39.2 per cent) of milk samples. Its mean value was 4.8 log10 CFU/mL. The mean values of Enterobacteriaceae, psychrotrophic microorganisms, lipolytes, proteolytes, yeasts and moulds together, coagulase-positive staphylococci and somatic cell count were 3.3 log10 CFU/mL, 4.1 log10 CFU/mL, 3.2 log10 CFU/mL, 3.9 log10 CFU/mL, 2.2 log10 CFU/mL, 2.8 log10 CFU/mL and 5.3 log10 cells/mL, respectively. E. coli was found in 33.3 per cent of milk samples, while Listeria monocytogenes and antibiotics were not detected. The inner surface contamination of the dispensing nozzles and chambers was estimated in the range from 1.8 log10 CFU to 6.0 log10 CFU/cm2. The presence of detergents and disinfectants in supply valve eluates was determined in more than one-third of the samples. The hygienic-technical conditions of observed VM show some deviations from specified hygienic-technical requirements which could influence the safety of raw milk. Research limitations/implications The data about construction and the cleaning practice of VM, included in the experiment, were not available during the inspection facility. Originality/value In the paper the pathogenic and also the spoilage microorganisms in milk in the combination with hygienic conditions of inside surfaces of VM were studied.

The efficiency of an enterprise’s power supply system depends on the quality of electricity and the losses of the latter in electrical networks; both being largely determined by the modes of voltage control and reactive power compensation. In practice, the problems of voltage control and reactive power compensation in power supply systems of industrial enterprises, including electric networks with a voltage of up to 1 kV, as well as 6, 10 kV and higher, are often solved separately. It triggers an irrational use of existing voltage control devices, underutilization of the installed capacity of compensating devices, and affects the voltage control in the electrical networks of the power supply organization. Since voltage management and compensation modes of reactive power are inseparable, they can be correctly determined only with the use of an integrated approach based on technical and economic criteria and taking into account technical requirements and local conditions. This article analyzes the mutual influence of voltage control and reactive power compensation modes in the electrical networks of industrial enterprises from the point of view of ensuring the quality of electricity and minimizing load power losses. The method and results of calculations (on the example of a specific industrial facility) for determining voltage deviations and losses in the electrical network as well as for selecting parameters for voltage control and reactive power compensation are presented. Due to the close relationship of these modes that affect all voltage levels, the effectiveness of measures cannot be ensured without the use of multifunctional devices for controlling the equipment of transformer substations.

Quality of Internal Audit is an activity which is very important and is a requirement in the implementation of ISO 9001:2000 standard, which aims to monitor the quality of the verifying the suitability and effectiveness of the implementation of the system of quality compared to the reference standards and policies that have been determined. Quality of Internal Audit is an assessment process and system to see whether the processes and systems in line with documented procedures and to see the effectiveness of the procedure. By doing this assessment, the company will know the condition or situation at this time. In the end, the results of this audit will be used as a tool / material improvement in the action / prevention of at improvement. Therefore, international standards emphasize the importance of audits as a means of monitoring and verification.  ISO 9001:2000 is an international standard for quality management system. ISO 9001:2000 define the requirements and recommendations for the design and evaluation of a quality management system, which has the goal to ensure that an organization will provide products that comply with the requirements specified. The ISO 9001:2000 is only quality management standard and is not a standard product. But expected that the product resulting from  international quality management system will has a suitable quality this.  Implementation of Internal Audit Quality in the PT. Murni Cahaya Pratama program showed that the Internal Audit Quality is in accordance with plans and procedures. Results of Internal Audit Quality use as the improvement efforts for both systems, processes and products. The quality management system ISO 9001:2000 which is applied in PT.

The scientific problem of economics “Managing the quality of human life” is formulated on the basis of artificial intelligence, algebra of logic and logical-probabilistic calculus. Managing the quality of human life is represented by managing the processes of his treatment, training and decision making. Events in these processes and the corresponding logical variables relate to the behavior of a person, other persons and infrastructure. The processes of the quality of human life are modeled, analyzed and managed with the participation of the person himself. Scenarios and structural, logical and probabilistic models of managing the quality of human life are given. Special software for quality management is described. The relationship of human quality of life and the digital economy is examined. We consider the role of public opinion in the management of the “bottom” based on the synthesis of many studies on the management of the economics and the state. The bottom management is also feedback from the top management.

Although North Korea is one of the most closed countries in the world, it has long been pursuing international cooperation with other countries in order to upgrade the quality of its film industry to international standards. Preceding studies on this topic have mainly focused on the political influences behind filmmaking in general and very few studies have exclusively dealt with North Korea’s international co-productions. In this respect, in order to develop a comprehensive understanding of the internalization strategy of North Korea’s film productions, this paper uses the global value chain as a framework for analysis. This approach helps understand the internationalization pattern of each value chain activity of film co-productions in terms of the film location and the methods for collaborating with foreign partners. By dividing the evolution of North Korea’s international co-productions into three periods since the 1980s, this paper finds that although North Korea has shown mixed results with different aspects of the film value chain, it has generally improved its internationalization over the three periods. This paper further provides strategic directions for North Korea by learning some of the successful Chinese experiences in the film sector regarding collaboration with foreign partners—to foster a win-win situation for all involved parties.

The article is focused on the communication with children with special educational needs. The main topic is alternative communication with children with sensory disorders and multiple disabilities. It explores the phenomenon of communication, citing current definitions developed by a number of authors, which place the emphasis on different aspects of this complex and multilayered process, with a special focus on alternative communication with the groups of special needs children mentioned in the title.The issue is investigated from a special pedagogical and from a social perspective.The author is especially interested in the exploration of the multiple strata of communication (the universal, functional and specific levels). Apart from the different forms, contents, methods and means of communication (the last of which is most commonly discussed in Bulgaria), the article is focused primarily on the important methodological issues related to this topic.One of these basic questions of methodology is the attempt not to place at the center of this process its bi-directional nature, its algorithm or code (sign language, Braille writing system, etc.), but instead to focus on the personalities of those involved in the interaction, their initiative, relationship and goals manifested in different communication situations (mutual influence, emancipation and therapy). Particular emphasis is given to therapy, i.e. the way of influencing the communication behavior of children with sensory disorders and multiple disabilities. It is not viewed as a unilateral process (stimulus-response), but as an interactive one, based on mutual influence. The relationship between the communicators is of utmost significance.Communication is characterized by a number of specific features. Those can mostly be found in the specificity of the communication situations (for example the interactive situations in the following pairs of communicators: deaf – hard of hearing; deaf – deaf; deaf-blind – deaf, etc.), in the presence of an intermediary (for example a sign language interpreter) and above all in the personalities of the communicators. They change the quality of communication. It is for this reason, and not just because of the different means of communication, that this interaction is defined as “alternative”, or more precisely, it is an alternative to the communication of children without disabilities.Based on the analyzed information, the author formulates a number of inferences and recommendations. The main conclusion is the following:When discussing alternative communication with children with special educational needs, the focus should shift from the specific means of communication towards the equally socially important quality of the complex process of communication, which is centered on the personality of the handicapped child.

Aim. The presented study aims to develop the methodology for assessing the quality of management of organizational transformation processes. Tasks. To achieve the set aim, the authors solve the following problems: determine the essence and content of socio-economic transformation, formulate quality assurance principles for the management of transformation processes, draw attention to the problem of selecting a unified quality criterion for the management of organizational transformation processes. Methods. This study uses general scientific methods of cognition, including analysis and synthesis. It also applies a systems approach to identify the major problems of assessing the quality of management of transformation processes, including the problem of selecting a unified quality criterion for the management of transformation processes and formulating the principles of ensuring the quality of management of transformation processes. Results. The global problem of managing transformation processes in the economic system consists in the complexity of the managed processes, which increases due to the multidimensionality, mutual influence, and the resulting uncertainty of interactions between the elements of the system. It is concluded that the methodology for assessing the quality of management of transformation processes is based on the principle of integrating separate measures to improve the quality of management of system elements into a single system of management actions and the principle of ensuring that management actions are primarily aimed at preventing possible negative consequences of the transformation of economic systems, i.e. reducing the potential impact of unfavorable events and their consequences. To assess the effectiveness of targeted management actions and productive actions aimed at organizing, controlling, and guiding the transformation process, the authors actualize the problem of selecting an adequate quality criterion for the management of transformation processes in economic systems and put forward a hypothesis about a possible unified criterion of management quality. Conclusions. The principle of integrating separate measures to improve the quality of management of system elements and the principle of ensuring that management actions are aimed at preventing possible negative consequences lie at the core of the methodology for assessing the quality of management of transformation processes in economic systems. The quality assessment methodology should be developed in the direction of finding a unified quality criterion for managing transformation processes in economic systems.
