Published: June 2021

The importance of physical training for a student`s health is underlined in the article. In addition, dependence between a level of physical training development and person`s health is defined. Physical training is not only a certain level of physical activity. Psycho-educational conditions of student`s physical training level as a source of its health are highlighted in the article too.
Reforming higher education in Ukraine requires finding new ways to solve the problem of personality formation, development of its physical, mental and spiritual strength. The priority task of the education system is to educate people in the spirit of responsible attitude to their own health and the health of others as the highest social value, the formation of a high level of health of student youth. One of the main tasks of the modern education system is to form a high level of physical culture in students. According to the latest scientific data, up to 90% of students have serious health problems, 50% or more are on the dispensary register, every fifth student (in the humanities - every third, and sometimes even second) is considered to be as preparatory and special medical group or just can`t be involved in physical activity; The level of more than 50% of young people studying in higher educational institutions of our country does not even meet the average level of the state standard of physical fitness, which guarantees stable health. This situation is due to the fact that for today's young people improving their health is not of paramount importance. At the same time, she does not have the necessary knowledge and life experience that would allow her to preserve her personality, to learn the optimal norms of life, based on the understanding of health as the greatest value. A significant part of the diseases of student youth has a so-called didactogenic nature, that is caused or provoked directly by the conditions of the educational process. In this situation, one of the main tasks of pedagogical education is to improve the physical culture of the student.

This article presents the results of the questionnaire and comparison, which allows determining the interest of first-year students in different types of physical activity at the National University of Water and Environmental Engineering.
The purpose of the study is to determine students’ interest in different types of physical activity offered as part of physical education in a higher educational institution.
According to their preferences, first-year students are suggested to choose either team sports (football, mini-football, volleyball, basketball), individual sports (table tennis, athletics, arm wrestling, weightlifting, boxing, swimming, chess, and checkers), or fitness activities for physical education classes in an educational institution.
The comparative analysis of the obtained data demonstrates the pattern of an increase from 65.1% in the 2015-2016 academic year to 71.0% in the 2020-2021 academic year in the number of young men, who have chosen and are engaged in a certain sport in an educational institution, and decrease from 34.9% in the 2015-2016 academic year to 29.0% in the 2020-2021 academic year in the number of young women interested in physical activity at the university.
Within five years, the number of young men choosing team sports has decreased from 75.6% in the 2015-2016 academic year to 63.3% in the 2020-2021 academic year, and the number of young men interested in individual sports has increased from 24.4 % in the 2015-2016 academic year to 36.7% in the 2020-2021 academic year.
Fitness classes remain the most popular among female students, although there has been a decrease in the number of young women choosing it for physical education from 83.3% to 71.8% over five years. Team sports are gaining more popularity among first-year female students with only 5.3% choosing them as part of physical education in an educational institution in the 2015-2016 academic year, to 10.2% in the 2020-2021 academic year. A gradual interest in individual sports from 11.4% to 18.0% is observed in young women over five years.
METHODS AND EQUIPMENT FOR HEATING AND MELTING HYDROCARBON MIXTURES IN VARIOUS INDUSTRIES (REVIEW)
Authors: Dolinskiy A.A. , Gorobets V.G. , Pereiaslavtseva O.O. 
Published: June 2021

The analysis of the methods and equipment in which the heating and melting of hydrocarbon mixtures in the pharmaceutical, food and oil refining industries is carried out has shown that reactors, baths, electric heaters, heating chambers, etc. are traditionally used for heating and melting hydrocarbon mixtures. Such methods are time consuming and energy consuming, large temperature gradients are observed, which leads to overheating of one part of the substance and underheating of another. In addition, the process of loading mixtures into boilers and their subsequent unloading is problematic and unsafe for contamination. Often containers with such substances are kept in unheated or poorly heated rooms (warehouses, workshops, etc.) and are too viscous to be unloaded from the container and transported to the next stages of production, which makes it difficult and slows down their melting. Most of the equipment is purchased abroad, for the purchase of which large funds are spent. The discovered existing problems give impetus to the development of new methods and equipment for the implementation of heating and melting processes.

Introduction. Global warming and so-called the “greenhouse effect” is one of the most discussed problems of physics and geopolitics, which has caused protest environmental movements in the world.
Problem Statement. Widely discussed are both anthropogenic (the emission of greenhouse gases into the atmosphere) and the natural concepts of global warming with the dramatic effects of climate change on the planet and individual regions.
Purpose. Evaluate the state of the problem, to present the results of research and measures to possible reduction of the greenhouse effect.
Materials and methods. Authoritative literature sources with the analysis of anthropogenic and natural factors of global warming are used, including with the explanation of the physical processes which are shown at solar-geomagnetic activity and other natural phenomena.
Results. The main causes and mechanisms of natural and man-made nature for the actual growth of greenhouse gas emissions and global temperature in the 20th century are identified and their estimates for the period up to 2100 are given.
Conclusions. Most likely, the effect of global warming on the planet's climate is totally due to natural causes of cosmogenic origin and somewhat exacerbated by the effects of industrial development of mankind. For the final solution of this problem it is necessary to fully and adequately conduct more in-depth complex experimental and theoretical-model studies taking into account various factors of geological, climatic, meteorological, thermophysical, astrophysical nature and application of modern methods of mathematical physics, statistics and probability theory. reasonable measures to adapt the economy and life to climate change.

Published: June 2021

The analysis of methods and means of experimental determination of the ratio of free and bound moisture in materials is carried out, and it is shown that most of the available measuring instruments do not allow investigating the ratio of free and bound moisture on representative samples of heterogeneous materials, therefore there is a need to create a specialized device for these purposes.
Thus, the concerned work is aimed to the development of the differential scanning calorimetry method for studying the state of liquids in inhomogeneous materials and the creation of a cryogenic calorimetric system for the implementation of this method.
On the basis of the performed analysis, recommendations were formulated for the development of a measuring system that is capable of examining representative samples of heterogeneous materials of various structures without the need for their preliminary grinding.
The method of differential scanning calorimetry has been improved for studying the state of water and organic liquids in inhomogeneous materials in a wide temperature range, which is based on the use of a three-cell differential measurement scheme, as well as the use of cells, the configuration of which allows taking into account the peculiarities of inhomogeneous raw materials.
A prototype of a cryogenic calorimetric system has been created, and a method for studying the metrological characteristics of such a system has been developed. On the basis of experimental studies, it has been established that the limits of the permissible relative measurement error of using the developed cryogenic calorimetric system are ± 5%, which corresponds to world analogues.

Published: June 2021

This study examines the behavior of stock prices following large price changes. It also examines the presence of disposition prone investors and effect of size on stock returns. The study uses daily prices data from Pakistan Stock Exchange (Formerly, Karachi Stock Exchange (KSE)) for the period of January 2001 to July 2012. Our findings suggest that winners perform better than losers after experiencing large price shocks thus showing a momentum behavior. This also suggests that most of the investors in KSE behave rationally and we do not find any evidence of disposition effect in KSE. Further, pooled regression estimates show that size is positively related to post-event abnormal returns. The fixed effect model shows the presence of unobservable firm-specific and time specific effects that account for price continuation.
Executing Strategic Risks Mitigation Plan Amidst VUCA Situation: A Lesson from COVID-19

Published: June 2021

This study focuses on how higher education institutions, or HEIs, may respond to future strategic risks of an unprecedented magnitude. As the business world grapples with the impact of the pandemic on the corporate strategies, so are the HEIs. The management of strategic risks tends to be viewed as ‘managing risk strategically’ and thus, they are often overlooked despite being found to be far more consequential than other traditional risks. Therefore, incorporating tactics to manage VUCA, which refers to volatility, uncertainty, complexity and ambiguity is timely and necessary in the new norm. The findings reveal that the seven basic steps required in developing a strategic risk mitigation plan (SRMP) namely: identify the risks, determine strategic risk triggers, describe the strategic risk (and where it is likely to strike), develop strategic risk mitigation plan, discuss strategic concerns, perform risk analysis and create the strategic risk map or scorecard. The pandemic experience shows that these seven basic steps can be narrowed into four broad categories of risk identification, risk analysis, risk assessment and taking appropriate corrective actions. The study also recommends a rigorous analysis of strategic factors related to the basis of strategies amidst challenging VUCA situations such as Covid-19.

Published: June 2021

Sticker system is a computer model which is coded with single and double-stranded molecules of DNA; meanwhile, Watson-Crick automata is the automata counterpart of the sticker system representing the biological properties of DNA. Both are the modelings of DNA molecules in DNA computing which use the feature of Watson-Crick complementarity. Formerly, Watson-Crick grammars which are classified into three classes have been introduced [1]. In this research, a grammar counterpart of sticker systems that uses the rule as in context-free grammar is introduced, known as a static Watson-Crick context-free grammar. The research finding on the computational power of these grammar shows that the family of context-free languages is strictly included in the family of static Watson-Crick context-free languages; the static Watson-Crick context-free grammars can generate non context-free languages; the family of Watson-Crick context-free languages is included in the family of static Watson-Crick context-free languages which are presented in terms of their hierarchy.

Analysis of Risk Factors with the Degree of Pelvic Organs Prolapse at Dr. Mohammad Hoesin General Hospital Palembang
Authors: Putra Hadrians Kesuma , Callista Zahra Aidi  , M. Zulkarnain  
Published: June 2021

Background. Pelvic organ prolapse (POP) is a condition in which one or more pelvic organs (consisting of the uterus, vaginal cuff, bladder, intestines, and rectum) or more are still in or out of the vagina. Risk factors that influence the incidence of POP consist of obstetric risk factors (number of parity and birth method) and non-obstetric risk factors (age, menopause, BMI, comorbid disease, and hypertension). The purpose of this study was to analyze the risk factors associated with the degree of POP.
Methods. This study is an observational study with a cross-sectional approach to 111 patients examined at the Department of Obstetrics and Gynecology, Dr. Mohammad Hoesin general hospital Palembang on January 2017 to December 2019, who was diagnosed with pelvic organ prolapse.
Results. The results showed the effect of variables with the degree of POP using the chi-square test, consisting of parity (p=0.007), birth method (p=<0.001), age (p=0.016), menopause (p=0.001), BMI (p =0.005), indicates that there is a significant effect on the degree of POP. Meanwhile, comorbid factors (p=0.481) and hypertension (p=0.415) did not show a significant relationship with the degree of POP. The results of the binary logistic regression analysis of all risk factors, the number of parity >4, overweight, and age 40 years, will have a 99.85% chance of experiencing grade 3 or 4 prolapse.
Conclusion. Age is the most dominant risk factor affecting the degree of pelvic organ prolapse, with 19 times the chance of developing POP 3 or 4 degrees.

Published: June 2021

Objective: To evaluate the effect of pruning on the agronomic variables and fruit quality of habanero peppers (Capsicum chinense Jacq.).
Methodology: Habanero peppers were pruned with two intensities, two shoots and three shoots. The control plants were not pruned. The experiment had a randomized block design with four replications. The experimental plots consisted of 50 plants established in rows at a distance of 1.2 m and 0.3 m among plants within a row. The evaluated variables were fruit yield, number of fruits per plant, fruit weight, fruit length and fruit diameter. Data were obtained from 10 harvests. For the analysis, the fruit quality, ash content, moisture, protein and crude fiber were determined.
Results: Plants with two and three shoots produced fruits of 4 and 3.99 cm in length. Plants with two and three shoots produced 42 and 48 % first quality fruits, whereas control plants produced only 10 % first quality fruits. The highest protein content in fruits at physiological ripeness (14 %) and commercial maturity (12 %) was observed in plants pruned to two shoots.
Implications: These results show the importance of crop management on the fruit quality of habanero peppers. Further studies are needed to have more information on the effects of crop management on the nutritional content of fruits.
Conclusion: The pruning of habanero pepper plants significantly influenced the fruit size, crude fiber and protein content in their fruits

Abstract in English:
Waqf (Islamic Endowment) has played a vital role in solving the social problems throughout the history. This paper aims at discussing the role of waqf in tackling the current global pandemic i.e., COVID -19. The paper discusses the possibility of using waqf as a mechanism for mitigating the negative effect of the COVID-19 pandemic. Considering the strong connection between waqf and the stipulated conditions by the waqif (donor), the paper analyses the views of the past and contemporary jurists on the extent of the permissibility of overriding the conditions of the donor (shart al-waqif) by the waqf management. This paper adopts qualitative methodology, and the textual analysis is being used by reviewing the literature and previous studies related to the issue. The paper reaches some conclusions, the most important of which are: the confirmation of the vital role of waqf in alleviating the severity of COVID-19 pandemic. Likewise, waqf management is permitted to breach the conditions of the waqif if the need is warranted and the objective of waqf is being considered. To avoid the challenges of shart al-waqif (conditions of the waqif), the paper proposes the establishment of waqf, which will be looking after the interest and affairs of the victims of crises “waqf for azamat”. Besides, the paper recommends to the researchers and waqf managements reviewing of the structure of the Crises-Waqf.
