The current state and problems of fishing industry development in the coastal regions of the Russian Fede­ra­tion

Abstract

The study discusses the key current problems and parameters of the mo­dern fishing industry in Russia. Given the EU and US restrictive measures towards Russia and reciprocal food import restrictions by our country, the condition of the domestic fishing industry is of particular interest. The article analyzes the quantitative parameters of the industry, identifies key leading companies, shows the dynamics of the number of enterprises in the coastal regions from 2007 to 2017, and reveals the geographical features of locating fid­hing enterprises. The authors analyse the companies’ financial indicators, as well as the change in the average annual number of employees. The study reveals that the key areas of activity for fishing companies are the regions of the Far East (Kamchatka, Primorsky Krai and the Sakhalin region) and the Murmansk, Kaliningrad regions and St. Petersburg. The main share of the catch is in the Far Eastern Federal District (more than 70 % of all fish and biological resources).

The influence of the transport factor on the investment competitiveness of coastal regions in the European part of Russia.

Abstract

Given the combination of the basic territorial growth factors, the coastal regions of the European part of Russia, where large urbanized spaces have already been developed or are being developed, are of the greatest potential compared to other regions of the country. It makes perfect sense to set up large economic centers capable of harnessing the benefits of agglomeration and seaside factors in such regions. A tool to improve the level of economic deve­lop­ment and investment attractiveness of these regions is the imp­le­mentation of large trasnsport infrastructure projects. The article analyzes how the implementation of projects under the Federal Target Program “Deve­lop­ment of the Transport System of Russia (2010—2021)” contributed to an increase in the economic efficiency of the transport industry in the region and, as a consequence, to an increase in the level of investment attractiveness. Using the classical economic and geographical research methods, the authors come to the conclusion that result-wise the regions under study are heterogeneous.

Coastal location as a development factor of the ci­ties in the Baltic region

Abstract

Population dynamics is one of the key categories of socio-economic development of territories. Cities, as the main carriers of innovative potential, need constant influx of human resources. The purpose of this article is to identify the nature of the influence of the cities’ coastal position on the dynamics of their population by the example of the Baltic region countries. The dependence of the popultaion dynamics on the coastal location of the city is studied with the reference to the methods of statistical and cartographic analysis. The authors have drawn the conclusion about a potentially higher ranking of coastal cities as centers of attraction for the population (primarily located at a distance of up to 50 km from the sea).

Coastal and recreation landscape of Kalining­rad: modern potential and prospects for spatial development

Abstract

The authors have conducted a comprehensive assessment of Kaliningrad suburban areas and identified the coastal landscape and recreation area within the ring road impact. Comprehensive analysis resulted in the typology of in­ter­nal areas considering how favorable they can be for further recreation and tou­rism development. The article brings about certain ideas  for the further use of Kaliningrad seaside suburbian recreational spaces in the frames of sus­tainable developmenthave.

Some features of external migration processes in the coastal regions of the Western borderlands of Russia

Abstract

The combination of two major economic and geographical factors — the presence of the border and access to the sea — largely determine the features of socio-economic development of the coastal regions of the Western borderlands of Russia and, as a consequence, the migration processes here. The purpose of the article is to identify the importance of these factors for migration in the coastal regions of the Western borderlands of Russia. The study showed that almost all the studied regions use their special economic and geographical location to get closer ties migration-wise with other russian regions and foreign countries, and are characterized by increased migration efficiency. A distinctive feature of the migration geography is intense migration turnover with neighboring countries: first of all, Finland, Estonia and Norway. The coastal position becomes an attractive factor for all the studied regions, except for the northern ones. The border can also affect the migration adversely both in the northern regions, and in the Leningrad region, St. Petersburg. The southern regions of Russia and the Kaliningrad region are the only ones to use their border position to make up the natural population decline at the expense of bordering states. Most regions are growing due to migration. The Northern Rus­sian regions are losing population. Migration here worthen the demo­gra­phic situation, even though there has been some equalization of gen­der dis­pa­ri­ties due to the outflow of the female population. The other recipient re­gions are characterized by a 'rejuvenation' of the population age structure and at the same time by worsening gender disparities. Applicants to universities and colleges are likely to leave for other regions of the Russian Federation (to the greatest extent this is typical for the northern regions). St. Petersburg, and to a lesser extent Rostov and Kaliningrad are the ones to attract students.

Obtaining certain heterocycles based on ureides and quinoid structures

Abstract

The work aims to obtain some heterocycles based on ureides and quinoid struc­tures. Derivatives of 1,3-benzodithiol-2, compounds based on toridol rep­resent biologically active compounds. They can be used as fungicides and bac­te­ricides and as microbiological corrosion inhibitors. The authors offer small-sta­ge syntheses for obtaining heterocycles of 4,7-dibrom-5-hydroxy-6-phenyl­ben­zoxytyol-2, 4,7-dibrom-5-hydroxy-6-(4-methoxyphenyl)-benzoxytyol-2.

Ultrasound anatomy of the skin: review

Abstract

A review of the skin ultrasound publications shows that this examination is one of the most popular diagnostic procedures in dermatology, cosmetology and oncology. Current research data defined the concept of "ultrasound ana­tomy of the skin", it is noted that an ultrasound examination of healthy skin with modern sensors can visualize three of its layers, appendages of skin and ves­sels of small diameter, located in the dermis and the upper layer of sub­cu­ta­neous fat tissue. The significance and possibilities of using the ultra­sound me­thod of skin examination for malignant neoplasms, primarily melanoma, have been shown. The high resolution of the method allows to draw conclusions about the formation size, its location in the skin layers, localization around ves­sels. The authors also describe the application of skin ultrasound in der­ma­tology and cosmetology, which is a new promising trend and thanks to which it is possible not only to visualize pathological changes in the skin, but also to mo­nitor the effectiveness of cosmetic procedures.

Young ‘s body mass index and its im¬pact on the frequency and variability of the heart rhythm at quiet and after phy¬sical load

Abstract

A medical examination on a selected group of young people demonstrated  a negative correlation between the body mass index and the heart rate at rest, which disappeared after some physical activity. Physical activity was observed to change the heart rate variability under the influence of the changes mag­nitude in the initial heart rate.  No correlation between body mass index and heart rate variability was established.
