When analyzing the reasons of the previous programs`failure, we usually focus on the following questions: timeliness of the program results obtaining, keeping to the budget frames, and the results compliance with the quality parameters specified. In other cases, the analysis confirms that the program and the team’s activity have been successfully finished, the payments to suppliers completed and the interested persons and users quite satisfied. It is much less frequently when the question of selecting the most pertinent area of changes is raised, as well as thequestion of readiness of the organization for the changes to occur due to the implementation of the program. The process of introducing a program, that assure changes, into organization activities is the subject of this article. The objectives: development of an instrument for analyzing the possibility of implementation of changes into the work of an organization and for evaluating the intensity of resistance to changes. The task is to analyze factors having an impact on the results and possibility of introducing changes within an organization, to consider and to ground the main problems and the sources of resistance to the changes. In our research, we used such methods as logical summarizing, analysis and synthesis, structural analysis. The results: a model of calculating the resistance to changes has been developed. This model takes account of the program implementation intensity and allows determining the total level of resistance to changes after successful completion of the program. The research showed that the total level can be both high and low, as the organization personnel, especially its top management, may not recognize the need for changes, or may strive for achieving stability of the company situation. In the course of the research, the basic features of the changes introducing programs have been defined and the basic problems appearing at an organization presented, particularly, those relating to its personnel. The problems have been classified as relating to the organization top management and directly relating to the team working on the program. Conclusions: the instruments foranalyzing the implementation of the program of changes or transformations within an organization have been obtained. The results achieved in the research bring the statement that if the resistance to changes is stronger than the organizational potential of a company, any benefits from the implementation of the program are leveled down. Therefore, the reduction of the general resistance to changes within an organization isneeded first, and only after this, any programs and projects can be implemented.

The role of branch information retrieval thesaurus for improving and increasing the effectiveness of information support of scientific research, carried out using the technology of selective dissemination of information, is analyzed in the paper. The selective dissemination system provides both individual and group information needs, as subscribers can be individual users as well as a group of users, namely scientific teams and virtual scientific teams whose members can be geographically distributed. Within the scientific team, subgroups can be formed engaged in research of different directions of their subject area. The information retrieval thesaurus is considered as a language model of a particular subject area. The development of information technologies creates the possibility of information modeling of a narrowly specialized subject area and data presentation in the form of thesaurus, which is a hypertext that reflects the hierarchically organized semantic structure of a specific subject area.

For determining ways of company development, ensuring the growth of profit in manufacture and sales of certain products, it has been proposed to use an algorithm of constructing a problem being inverse to primal-dual one, for minimization of the project costs. The primal and the inverse problems contribute to improving the efficiency of calculation when determining approaches for minimization of costs. This pair of problems is mutually conjugate. The proposed rigorous approach to obtaining the algorithm of constructing a dual problem is based on the following statement: a problem being inverse to a dual one is a primal (original) problem. The authors have proposed and rigorously proven the algorithm of a general approach to the construction of conjugate problem pairs. Formalization of the algorithm developed allows obtaining easily correct pairs of known dual problems. This permitted proposing and proving the truth of the algorithm of constructing a dual problem for the arbitrary form of a primal problem representation.

A complex system of social and educational inclusion needs competent analysis to make it possible proper management and comprehensive improvement. To analyze one of the actual facets of such a system, namely, its ICT support, it is necessary to take into account the various needs of socially vulnerable people. A set of guidance to web accessibility is a convenient instrument, that provides various approaches in designing goods and technologies. Among other, such guidance helps to design websites with no access barriers, which is extremely important for people with special needs. To analyze the websites and different online resources, which might be of interest to a person with special needs during the social and educational inclusion, a list of characteristics was developed. It must be taken into account the classification and the structure of information materials, website`s structure, design, etc. The unification of the ICT for people, involved in educational and social inclusion, will improve informational and technological support of such process.

The paper examines modern ways to improve the efficiency of information perception using multimedia technology, thus ensuring the use of a powerful new tool for understanding of information by persons with various forms of nosology. The use of assistive computer technologies for people with disabilities is investigated. The peculiarities of formation of multimedia information content for users with special needs were analyzed. The digital library as a set of information technology services is proposed making multimedia information content accessible to users with various forms of nosology. It was investigated that in spite of rapid development of modern communication means and assistive technologies their use is limited for people with disabilities, in particular for hearing impaired people. Most of available technologies for hearing impaired people translate speech into text. As was shown this approach is not fairly efficient because Sign language turned out to be the most convenient way of communication for the respondents.
