Ecological and geographical confinement of rare medicinal plants of forest flora of the Kuznetski Alatau in need of protection
The subject of the study was rare medicinal plants of the forest flora of the Kuznetski Alatau. The species used in officinal, folk and homeopathic medicine were listed as medicinal plants. The list of rare medicinal plants of forest flora of the Kuznetski Alatau in need of protection is recommended on the basis of field research conducted by the author. There are 12 species in the list. The method of regular embedding of key areas and a network of expeditionary routes were used in order to select field data, which enables a reliable estimation of the floristic richness of forest flora of the studied region. Identification of rare species was based on their occurrence and abundance. The basis for ecological and geographical analysis was the assignment of each species by the confinement of its belt and zone to a particular ecological-geographical group. The basis of chronological analysis was assigning each species to a specific geographical group according to a character of areal. The distribution within the Kuznetski Alatau inside geobotanical districts is shown for each species. Endemic and relicts are indicated. Nemoral elements, which are rare in the forests of the Kuznetski Alatau, are attributed to relicts of coniferous-deciduous forests. A complex coenotic character of the studied spectrum of flora, due to substantial participation of species, confined to light coniferous, deciduous and dark coniferous forests, was found. However, the proportion of species of dark coniferous plant communities is considerably inferior to the participation of species associated with cenoses of coniferous and deciduous forests. These exact species are more plastic coenotically and environmentally and they represent the majority of additional, natural mountainous and additional mountainous species

Some universal limits for nonhomogeneous birth and death processes
In this paper we consider nonhomogeneous birth and death processes (BDP) with periodic rates. Two important parameters are studied, which are helpful to describe a nonhomogeneous BDP X = X(t), t≥ 0: the limiting mean value (namely, the mean length of the queue at a given time t) and the double mean (i.e. the mean length of the queue for the whole duration of the BDP). We find conditions of existence of the means and determine bounds for their values, involving also the truncated BDP XN. Finally we present some examples where these bounds are used in order to approximate the double mean
Особенности активационных процессов коры головного мозга при олигоменорее у подростков
The article presents the data on the epidemiology of menstrual cycle disorders of Krasnoyarsk
teenagers. The increase in the frequency of oligomenorrhea, indicating worsening of functional
disorders of the reproductive system, has been revealed. Due to the possible relation between
oligomenorrhea development and disruption of activation processes of cerebral cortex, the dynamic
measurement of omega-potential of cerebral hemispheres was conducted. The study was carried out
in a group of female patients before the hormone therapy and after its completion. It was revealed
that the basic values of the omega-potential of the girls with oligomenorrhea are characterized with
its increase, indicating a high level of mental stress. The results have revealed the dependence of
normalization of the activation processes of the cerebral cortex and the option of hormonal correction
of oligomenorrhea.В статье приводятся данные по эпидемиологии нарушения менструального цикла подростков
г. Красноярска. Выявлено увеличение частоты олигоменореи, что свидетельствует об
усугублении функциональных расстройств репродуктивной системы. В связи с возможной
зависимостью развития олигоменореи и нарушением активационных процессов коры головного
мозга проведено динамическое измерение омега-потенциала полушарий мозга. Исследование
проведено в группе пациенток до начала гормональной терапии и после ее окончания. Выявлено,
что базовые значения омега-потенциала у девушек с олигоменореей характеризуются его
повышением, что свидетельствует о высоком уровне психического напряжения. Выявлена
зависимость нормализации активационных процессов коры головного мозга и варианта
гормональной коррекции олигоменореи
Development of internal control methodology by using statistical methods of variability assessment of material flow business processes
Variability or instability is one of the key features of any process, including business processes of material flow internal control. Variability is a characteristic of all natural systems and technical processes. The objects which properties can be characterized via certain parameters arise at the output of any process. The article discloses the feasibility of using the statistical methods in the internal control system of business entities; in this case the focus is on the method of identifying the causes of variability using control charts of various types (Shewhart control charts) as a prime tool. The view points regarding variability of famous academic economists who researched the business process management issues are also considered. Authors’ classification of business process variation on types of material flow internal control with the allocation of controlled and uncontrolled variation is taken as the basis of the proposed application. The method of using control charts in estimating the efficiency of material flow internal control business processes is described in detail.peer-reviewe

Time perspective and significance of life events in adolescence
This article presents the results of a study of the relationship between the time perspective and themes of significant life events in adolescence. The study involved 1,394 boys and girls aged 14 to 23 years. It was revealed that there is an age-related multidirectional dynamics in the representation of the following periods: “studying at school”, “vocational training”, “professional autonomy”, “future”, “open present”. For example, modern youth associate “learning at school” positively with entertainment and negatively with study and work in the past and with communication and contacts in the future. The period of “professional training” is associated with all significant events in their lives except for events related to entertainment in the future. The period of “professional autonomy” is associated with events aimed at business (including both professional activity and study) both in the past and in the future. All important events in the present depend on the desire to possess some qualities, properties, skills. And at the same time, the significance of communication and entertainment in the past and the importance of entertainment and specific activities (educational and professional) in the future are associated with this desire. The results of the study may be of interest for the organization of work with high school students and students on the formation of a time perspective of the future
ROLE OF INFORMAL ASSESSMENT IN IMPROVING STUDENTS` REFLECTION
Purpose. The article is devoted to various methods of informal assessment and their potential for developing students’ reflective skills. The authors analyze different theories and approaches to reflective learning in order to design tools for enhancing students’ reflective abilities.
Methodology. The data obtained through the research are evaluated and interpreted on the basis of the descriptive approach. The authors also adopt the reflective-activity approach for designing a set of reflective statements.
Results. The authors study the main features of informal assessment, compare and contrast them with the forms of formal assessment pointing out that new approaches to assessment such as Learning Oriented Assessment (LOA) should be adopted in order to promote learning, motivate students and encourage their autonomy. Special attention is given to feedback as an LOA component, which correlates with the concept of reflective learning. The authors analyze various theories of reflective learning and design a system of reflective statement, which could be used as a means of practical development of students’ reflective abilities.
Practical implications. The results of the research can be applied in teaching practice of various disciplines at higher educational establishments
Innovation impact analysis model in the education system (on the example of regional innovative projects)
© 2017. This paper elaborates an innovation impact model based on the analysis of the design of innovative projects' competitions ("single customers" (linearity) - "partnerships" (complexity)), and innovative projects' objectives in relation to changes in education features ("conforming" - "transforming"). It presents expert criticism of the innovation impact analysis model and innovation classifications in the process of approbation of the model, indicating the imperfection of the model in terms of considering the "power" of the impact of innovative projects on education features
