DATA MINING OF USERS' SOCIAL NETWORK PROFILE FOR DETERMINATION OF TYPOLOGY OF THE CONSUMER. Part I
DescriptionThe article considers a new approach to the definition of the type and psycho type of consumer  social network user, using psychographics methods, data mining and statistical techniques and analytical tools. In the study, we executed testing of respondents in order to identify the properties of their socioeconomic preferences. Experimental and research work aimed at solving the problem described in the article, was divided into several complementary to each other and interconnected parts. The article presents the first part of the work, which includes the decision of 3 objectives, namely to obtain quantitative, statistical data on the properties of consumer preferences of users of the social network "VKontakte"; identifying groups of consumers with different severity of sociopsychological properties of preferences; definition of psycho type of user with a set of inherent characteristics and behavior patterns. To achieve the objectives we developed comprehensive software, called "MindScore", with main components at this stage  1) the module for user authorization through the app of social network "VKontakte" and for extraction data of its social profile, 2) the module for processing and analysis data. In the study we have given rise to the creation of unique algorithms for personality mining using dataset of user profile social network

ISSUES IN IMPLEMENTING MARKER BASED TRACKING ON MASS MOBILE DEVICES
DescriptionTracking is a vast field of research associated with navigation, robotics, and virtual environments (virtual reality). Tracking for augmented reality requires higher level of precision, increased range of action, as well as work with a wider variety of input data. It is important that augmented reality technology requires tracking in real time, which also complicates the task. Correct visualization of objects in threedimensional space requires six degrees of freedom tracking: three position values (x, y, z) and three angles (rotation around the respective axes) to determine the orientation. To solve this problem, different approaches and sensor types are being used. In this article, we present a brief history of the development of tracking technology and analyze the current approaches to implement the process of tracking on mass mobile devices such as smartphones and tablet computers. We also describe some issues in implementing optical marker based tracking for visualization of large scale models

Description
The article presents results of the study to assess the effectiveness of credit funds in interacting agricultural (AES) and processing (PP) agricultural enterprises. The conducted studies are a continuation of the scientific work on the development of mathematical models of interaction of the enterprises of the AES and PP, are shown in the articles [1, 2, 3]. This article presents the authors’ developed set of models of management of credit funds of interacting enterprises of an agroindustrial complex. It includes mathematical models of economic efficiency of agricultural enterprises considering the use of loan funds, as well as the assessment of the maximum amount of interest rate of the loan and the minimum selling prices of units of finished agricultural products; a mathematical model of the economic efficiency of the processing plant taking into account credit obligations of the agricultural enterprise and a model for the calculation of the minimum selling prices of its finished products; a mathematical model of the economic efficiency of the combined entity with all its loans. We have proposed a model to calculate the minimum selling prices of its finished products

Description
In the article we have reflected a relationship between the parameters of the research activities of scientific and pedagogical collectives and the characteristics of the educational environment in higher education. It is known that the research activities of scientific and pedagogical workers and teams  an integral part functioning of the higher education institution (and improving its efficiency is one of the most important problems). The authors proved that parameters reflecting research activity of scientific and pedagogical higher education of institution employees characterize the aspects of the educational environment as its latitude, intensity, social activity, coherence, mobility, stability, reliability and efficiency. It is caused by the fact that the research activities of scientific and pedagogical workers  a multifaceted social and cultural phenomenon. The idea of the diagnosis of the educational environment of a higher educational institution and its structural units, based on an assessment of scientometric indicators (criteria for research productivity), can be completely suitable for international and Russian requirements: the wellknown Shanghai procedure shifts the emphasis on the evaluation of various aspects of the research activities in higher education; serious attention to assessing the research activity focuses and Russian technique diagnostic efficiency of higher education institutions. This is logical and soundly: if the educational environment of a higher educational institution is not a center of science, then it cannot have effectively and competitive graduates, because Research and pedagogical staff  the governing factor in the educational process. Based on previously developed models of research activities in scientific and pedagogical collectives, as well as on generally accepted models of educational environments, the authors have proposed a method for the diagnosis of the educational environment, based on an assessment of scientometric indicators  parameters reflecting the impact of the research activities of scientific and pedagogical workers. Obtained results may be the theoretical basis for further scientific understanding of the problem of increasing the productivity of research activities in higher education, as well as problems  increasing the competitiveness of educational environments. The practical significance of the results of this study  the possibility of their use in the system of sociopedagogical monitoring  monitoring of productivity the research activities and effectiveness of educational environments. Methods of investigation: modeling, methods of the theory of sets and relations, methods of probability theory and mathematical statistics, methods of the theory of limits, methods of linear algebra and analytic geometry, multiparameter analysis of the systems and methods of quality control (latent variables theory). Methodological bases of research: a systematic, metasystem, qualimetric, sociological and probabilistic and statistical approaches

PARAMETERS OF RESEARCH ACTIVITY OF STUDENTS AS CRITERIA FOR DIAGNOSTICS OF EDUCATIONAL ENVIRONMENT
DescriptionThe article reflects the relationship between the parameters of research activities of students and the characteristics of the educational environment in higher education. It is known that the research activity of students is an integral part of the educational process, therefore, the parameters of research activity can and should be indicator variables reflecting certain aspects of the educational environment. According to modern views, all types of research activities of students (educational, research, scientific and practical and research) is the most important mechanism for the development of their research competence. In addition, the parameters of research activities of students  the reflection of the relationship of scientific and educational activities in higher education, and this  one of the most important factors of competitiveness of the educational environment. The authors substantiate that the parameters reflecting the research activity of students characterize, first of all, such aspects of the educational environment as its intensity, social activity, dominance, coherence, mobility, stability, reliability and efficiency. This is due to the fact that the research activity of students is a transdisciplinary process that depends on the same factors as the educational process as a whole and is characterized by the same didactic goals (tasks) as the educational process as a whole. In identifying the relationship between the parameters of research activities of students and the characteristics of the educational environment, the authors also took into account the relevance of such a task as ensuring continuity between levels of continuing education. The theoretical significance of the results of this study is that they can be the basis for further scientific understanding of the problems of the quality of education and the effectiveness of educational environments, the practical significance is that they can be applied in the systems of sociopedagogical and psychopedagogical monitoring and the effectiveness of the educational environment, as well as monitoring the student's personal and professional development). Methodological bases of research: system, sociological, competence, probabilitystatistical and qualimetric approaches (leading methodological basis  competence approach). Research methods: modeling; methods of graph theory, sets and relations; systemiccognitive analysis; methods of qualimetry (theory of latent variables); methods of mathematical statistics (first of all  the method of rocky scree); methods of the theory of limits
