The study clarifies the concept of spatial networking inherent of various forms of interactions within the territorial socio-economic system of a region. The author offers a classification of spatial networks, identifies and describes types of spatial boundaries of different types of territorial communities: geographic, organizational, cognitive, cultural, institutional, social and technological. The complex of factors and conditions that influence the dynamics of the boundaries of spatial networking are defined.

The paper examines the role of research institutions in the system of innovation security of the region and highlights vital interests and security threats to the regional innovation system in the field of research. The author describes important factors having a positive and a negative impact on the competitiveness of the research component of the innovation system of the region. The evaluation of the development of science in the Kaliningrad region in the Soviet (1958—1985) and contemporary (2000—2014) periods of history is undertaken. It is concluded that the regional innovation system of the Kaliningrad region, having undergone a major structural adjustment in the 1990s, is currently in its formative stage, and the research sector makes a significant contribution to its formation. Both the strengths of the research component of the innovation system of the Kaliningrad region — its competitive advantages, and the weaknesses — threats to its innovative security, are defined.

This article analyses images of environmental risks using the village of Nivenskoe as an example. Relevance of the research is caused by the fact that modern control systems of technogenic and ecological safety are based on risk assessment methods. Since media play a most significant role in the formation of public opinion and direct perception of risks in public space, communication of risks can be an instrument of latent manipulation with public opinion. The Internet and printed local media have served as an object of research. Results of the research confirm a hypothesis that images crested by media usually do not correspond to real technical aspect of environmental risks and are addressed as a political problem.

The article presents the analysis of ash-content in different systematic groups of vegetation of the western and northern industrial zones of Gomel. These industrial zones differ in the degree of their technogenic influence on the environment. The study shows the dominance of Aster and Leguminous plants. The ash-content in the Leguminous plants depended on the degree of technogenic influence.

Individual characteristics of each patient and appropriate choice of treatment based on the results of diagnostics present a foundation for the elaboration of programmes aimed at preventing periodontal disease. The evaluation of these activities requires new approaches to their organization, development and planning for preventing the development of pathology of the periodontium and improving the effectiveness of therapeutic manipulations for reducing complications.

Liver size varies widely according to age and different body types. Palpation and percussion are standard techniques to measure liver size, but are not accurate enough to detect a small increase. Accurate measurement of the liver by sonography is particularly relevant when a patient is suspected to have hepatitis. According to a number of validated sources, liver length varies greatly depending on the modalities and techniques used by the ultrasound specialist. Ultrasound liver size measurement has not become a routine procedure since a reliable and reproducible ultrasound method has not been established so far. The article describes the results of different methods of liver size measurement and as well as variations in the normal size depending on the age of the patient and his/her body type.
