Movement activity as a factor of bad habits prevention among the students

Abstract: The rationale for this study is to determine that movement activity is an important part of students’ healthy lifestyle. As a result of the high school physical education system reforming (exclusion of the compulsory physical training classes), students lose motivation to motor activity and acquire harmful habits (tobacco-smoking, drinking alcohol, and other). The purpose of the article is to study the impact of motor activity on the number of students with tobacco habits and alcohol consumption. Methods of research: analysis of the records of physical culture and sports activities of students (to determine the scope and nature of their motor activity); anonymous questionnaire (to determine the number of students with harmful habits); comparative analysis (to determine the factor of influence of physical activity on indicators of the number of students with harmful habits). The number of male and female students of different courses who used alcohol and had a habit of tobacco smoking was studied. We revealed that the number of students with problems with alcohol and smoking habits increased among persons who didn’t have regular physical activity vs. those who had, especially among male students (p<0.05). So as a result of exclusion of the compulsory physical training classes from the educational programme the number of students with bad health will be increased, and the efficiency of their education will reduce. It was determined that the number of students with a predisposition to drinking alcohol among men is 7.7%, and among women − 4.1%; the average rate of people who have a habit of smoking among male students is 16.1%, and among female students − 5.9%.We showed that movement activity is an effective factor in preventing harmful habits (tobacco smoking and drinking alcohol) among both male and female students.

Kwestie i spory religijne na terenie Rusi Zakarpackiej w czechosłowackim epizodzie jej dziejów

Abstract: The issues and religious disputes in Carpathian Ruthenia in Czechoslovak period and its echoes behind the Atlantic In Subcarpathian Ruthenia in the interwar period – during her membership in Czechoslovakia, one of the sharper conflict was a dispute between two Christian churches. In fact, the rivalry of the two churches began even earlier, during the Hungarian reign – before 1918, but broke out with the new intensity in the interwar period. The Czech authorities, retained neutrality in the confessional disputes, unlike its predecessors, favoring the units. The dispute also had political significance – namely in the conflict between national orientations: Russophile and Ukrainian. Both churches were not monoliths and shook them as internal tensions, including politically motivated ones. Religious conflicts had also their roots and echoes on the other side of the Atlantic. Part of the Greek-Catholic immigrants Transcarpathian did not want to submit to the American Catholic hierarchy, who failed to see the specifics of this group of emigrants. During the period between the Uniate Church recorded outflow faithful to the Orthodox Church, by almost 5% (from nearly 55% to 50.2%) and Orthodox increase by approximately the same proportion – over 15% of the population. Kwestie i spory religijne na terenie Rusi Zakarpackiej w czechoslowackim epizodzie jej dziejow Na Rusi Zakarpackiej w okresie miedzywojennym, podczas jej przynalezności do Czechoslowacji, jednym z ostrzejszych konfliktow byl spor pomiedzy dwoma chrześcijanskimi Kościolami. Faktycznie rywalizacja dwoch Kościolow zaczela sie wcześniej, za rządow wegierskich – przed 1918 rokiem, ale rozgorzala z nową intensywnością w okresie miedzywojennym, kiedy wladze czeskie, zachowywaly neutralnośc w tych konfesyjnych sporach, w przeciwienstwie od poprzednikow, faworyzujących unitow. Spor mial takze aspekt polityczny – ocierając sie o konflikt miedzy orientacjami narodowymi: ukrainską i rosyjską. Oba Kościoly nie byly monolitami i wstrząsaly nimi takze wewnetrzne napiecia, w tym na tle politycznym. Konflikty na tle religijnym mialy tez swoje zaoceaniczne korzenie i echa, gdzie cześc grekokatolickich emigrantow zakarpackich nie chciala sie podporządkowac amerykanskiej hierarchii katolickiej, nie dostrzegającej specyfiki tej grupy wychodźcow. Podczas okresu miedzywojennego Kościol unicki odnotowal odplyw wiernych na rzecz prawoslawia, o prawie 5% (z prawie 55 do 50,2%), a Cerkiew Prawoslawna przyrost o mniej wiecej o ten sam odsetek – do ponad 15% mieszkancow.

On Solving an Optimization Problem with Interval Coefficients

Abstract: In this paper, a decision-making problem where alternatives are estimated with interval parameters and the feasible set is defined using interval constraints is considered. Based on the assumption that the objective function and constraints are linear, a linear optimization problem with interval coefficients in the objective function and constraints was specified. For solving this problem, the approach of its reduction to optimization problem with a scalar objective function and scalar constraints was proposed. This approach consists of two steps. At the first step, we reduce the problem with interval coefficients to a lexicographical optimization problem with lexicographical constraints. At the second step, we reduce this lexicographic optimization problem to a problem with a single scalar objective function and scalar constraints. This makes it possible to use well-known classical methods of real-valued optimization theory for solving this problem.

Agroecological Aspects of Cultivation Shiitake Mushroom in Ukraine

Abstract: Shiitake mushroom (Lentinula edodes (Berk.) Pegl.) is currently the second mostly cultivated mushroom in the world. It’s valued for its exotic taste, flavor and nutritional value. The aim of our work is complex analysis of agroecological aspects of cultivation Lentinula edodes. There are two main cultivation techniques – growing on logs and on sawdust substrate. Cultivation on logs is considered traditional in Far East (Japan, China, Korea, etc.) and cultivation on sawdust substrate is new and very popular in USA, Europe. In Ukraine shiitake is still novelty, only a few farms are growing this mushroom. Main challenges for Ukrainian growers are: choosing of right cultivation technique, need of introduction of the product to local consumers, price support and ensures the profitability of production. The article provides general information about shiitake mushroom, growing techniques and cultivation in Ukraine.

Implementation and Guarantee of Human Right to Rest in the System of Modern International Relations

Abstract: This article analyzes the main challenges faced by tourists during the implementation of their right to rest. Various measures taken by states for strengthening national security are arising out of numerous terrorist threats and increasing illegal migration. All these measures are an obstacle to the effective development of tourism. Consumers and producers of travel services are forced to exercise their activity by taking into account many barriers standing in their way. Everyone's right to rest includes the right of freedom of movement, the right to liberty and personal inviolability, the right to a standard of living necessary for the maintenance of health and welfare etc. All these rights are guaranteed by major international legal instruments. Along with these rights, they contain provisions that restrict them. The article examines the main limitation of the above rights and their causes. The author explores scientific review of restrictions on the rights of freedom of movement and migration law of modern states. Violations of Human Rights are analyzed based on the example of cases reviewed by the European Court of Human Rights and the Court of Justice of the European Union. Security and human rights are two key issues that the international community is now trying to combine in regulation without any harm to anyone. The selectivity of modern visa policies provides the basis for the appearance of discrimination. This, however, is not recognized and condemned by international law. Creation of the unified international legal rules based on respect of human rights and security guarantees will facilitate the development of tourism and economy growth of developed and developing countries.
