Published: June 2021

Fitness is, first of all, a healthy way of life. Fitness is a person's response to the growth of life. The desire to be in shape is a natural desire, especially relevant now that illness and bad habits have become a real luxury. Fitness - a chance to change the quality of life without radicalism and excessive effort; the most perfect training system to date, which has absorbed all the most effective methods of "body education" (Medina EN 2000). There is no single and final definition of fitness. There is still a discrepancy even in the spelling of the word "fitness".

The English language often uses the expression "To be fit", which can be translated as "to be in shape". In the textbook (Hawley ET, Franks BD 2000) "Health Fitness" you can read the following definition of different categories of fitness: general fitness - is the pursuit of optimal quality of life, including social, mental, spiritual and physical components. The term "positive health" is also used.

Physical culture, being one of the facets of general culture, largely determines human behavior at work, in education, in everyday life, in communication. The development of physical culture and sports is one of the most important components of a strong social policy that can ensure the real implementation of humanistic ideals, values and norms, open a wide space for identifying people's abilities, meeting their interests and needs.

Nowadays, sport has become more and more part of people's lives. Deep study of human physiology makes theoretical justifications in sports. Trainings are thought over so that they most organically fit into the general vital activity of a human body. Classes began not only to be guided by the principle of "do no harm", but also seeks to bring the greatest benefit to man. Probably, it is possible to notice that one of theoretically the most substantiated kinds of sports now becomes fitness. It should also be noted that fitness is a sport that, in addition to physical satisfaction, brings moral satisfaction.

The ability to maintain high speed and accuracy of sensorimotor reactions for a long time under the influence of various interfering factors is an important component in the training structure of future law enforcement officers. Improving of the sensorimotor reactions of higher education students in institutions that train police officers takes place in the process of the discipline "Special Physical Training". Methods of general physical training (sports games, competitive methods), as well as, methods of simulating service situations (attempt of the offender to get the weapon, group interaction of police, protection from the threat of weapons, protection from blows with hands and feet) are used to achieve this purpose. We conducted a study of the complex reaction of choice of cadets in the normal conditions and under the influence of interfering factors. The results show that male cadets and some women as a result of two years training significantly improve the resistance of sensorimotor responses to interfering factors (the speed of a complex reaction of choice without interference, with interference, the total number of errors). The results show that the traditional curriculum of the discipline "Special Physical Training" in higher education institutions with specific training conditions, which provide training of police officers, effectively helps to improve the stability of sensorimotor responses of cadets. Improving the efficiency of the training process in the direction of increasing the stability of sensorimotor responses of female cadets requires special attention.

Along with a pronounced antitumor effect, Doxorubicin causes systemic effects with damage to vital organs, including the heart. It prompts the search for ways to prevent the cardiotoxic effect of the drug, one of which could be its intravesical administration. The aim of the study was to develop a method of serial intravesical administration of Doxorubicin in medium therapeutic doses in an experiment and to evaluate the cardiotoxic effect of the drug. 42 female Wistar rats were included in the study. The control group consisted of 7 intact rats. The experimental group consisted of 35 rats who received intravesical chemotherapy with Doxorubicin at a dose of 5 mg/kg once a week for 5 weeks. On days 7th, 14th, 21st, 28th, 35th the hearts of experimental animals were taken for morphological examination. Histomorphometrically determined: the diameter of cardiomyocytes (in the middle part) and the transverse diameter of their nucleus, the width of the interstitial space (endo- and perimysium). The data of histomorphological and histomorphometric examination of the myocardium testified that all animals of the experimental group had a circulatory disorder in the heart muscle at the level of hemomicrocirculation. Such changes led to cardiomyocyte hypotrophy, interstitial edema and fibrosis. During intravesical chemotherapy, the animals showed marked changes in the myocardium, such as expansion of the endomysial zone, due to capillary congestion and edema, in comparison with animals of the intact group. At the end of the experiment, the animals of the experimental group retained the expansion of the endomysial zone, mainly due to interstitial fibrosis. Such changes indicate myocardial hypoxemia with damage and death of cardiomyocytes, activation of interstitial and replacement collagen formation. The obtained morphological data partially indicate the development of dilated cardiomyopathy in experimental animals. However, these changes were less pronounced than the previously described changes that occur after systemic administration of the drug. Additional studies of the electrophysiological activity of the heart and biochemical markers will make it possible to fully assess the degree of cardiotoxicity of Doxorubicin after its intravesical administration. Thus, serial intravesical administration of Doxorubicin in moderate therapeutic doses according to the proposed method causes changes in the myocardium of experimental animals, which are partially similar to the changes in the heart of people receiving chemotherapy with this drug.

Human health and its optimal functional state depend on the efficiency of the body’s regulatory systems that respond to changes in a complex of exogenous and endogenous factors, ensuring timely adaptation to changing living conditions. However, natural factors, which largely determined the direction of evolution of the human body, are increasingly receding into the background, giving way to anthropogenic factors, including working conditions. That is why the aim of the scientific article was to study the state of the cardio-respiratory system in workers who are involved in various production processes, depending on their body constitution. The study of central and cerebral hemodynamics was conducted on men aged 21-35 years (90 people in total), which were divided into 3 groups, 30 persons in each: involved in industrial production, agricultural workers and residents of relatively environmentally friendly areas of Volyn region. At the first stage of the study, absolute anthropometric indicators (age, height, weight, chest circumference) were measured and the integrated indicator (Pignet index) was calculated. The next stage of the study involved functional diagnostics of the cardiovascular system of the subjects using functional ECG techniques, Kubicek rheography and rheoencephalography. Registration and analysis of relevant indicators was carried out using a set of hardware and software survey methods “Askold” (Kyiv, 1997). Statistical analysis of intergroup differences was performed using Student’s t-test and Man-Whitney U-test, the level of relationship between the individual parameters was assessed by the Pearson method. It is proved that the anthropometric indicators of persons exposed to chronic exposure to harmful production factors do not differ in the group of persons involved in industrial production and in agriculture. It is shown that in subjects who are exposed to negative factors of the production environment for a long time (both during the production of agricultural products and in an industrial enterprise) there are compensatory changes in central hemodynamics (stroke volume and myocardial capacity) compared with the control group persons from ecologically clean areas of Volyn region. Employees of the industrial enterprise showed signs of deterioration of the amplitude-time characteristics of cerebral blood flow in both hemispheres, as evidenced by indicators of rapid filling time, rheographic coefficient and average blood flow velocity. These parameters differ from similar parameters of agricultural workers and residents of relatively environmentally friendly regions. Thus, the identified features of the indicators in the groups of subjects exposed to chronic exposure to negative factors of the production environment, indicate the functional nature of the identified changes that are compensatory in nature.

According to statistics, every fifth married couple has problems with pregnancy. It is known that among all the factors of infertility, the first place is occupied by the tubal-peritoneal factor, and the most common cause of non-pregnancy is a violation of the receptive ability of the endometrium. In the study of the endometrium in patients with unsuccessful attempts at assisted reproductive technologies and severe endometrial insufficiency, there are changes in receptivity, impaired development of foaming, decreased expression of implantation molecules. The development of new methods for correcting the receptive function of the endometrium remains an important step. It should be noted that currently there are no standardized approaches to pre-pregnancy preparation of endometrial receptivity with pronounced signs of lag. Also today, special attention is paid to the impact of carbohydrate metabolism disorders on women's reproductive health. Based on the analysis of literature data and the results of their own retrospective observations, the team of authors identified the role of disorders of carbohydrate metabolism and autoimmunization with food allergens in the violation of endometrial receptivity. It is noted that severe endometrial insufficiency is significantly correlated with an increase in the number of women with disorders of carbohydrate metabolism. The initial algorithm of preliminary preparation of the endometrium of normal immune systems and carbohydrate conversion of heirs in accordance with the mode of processing and analysis is developed and offered. Created, adherence to the elimination diet increases the receptivity of the endometrium with a collection of women according to standard schemes. The proposed training algorithm also improves the overall health of patients, reduces metabolic manifestations.The results of the studies indicate the need for a differentiated approach to the correction of endometrial receptivity and pre-pregnancy preparation of the endometrium before subsequent cycles of ART.

Published: June 2021

Obtaining high quality rectified ethyl alcohol is a priority for the further development of the alcohol industry. The solution to this urgent problem is possible under the condition of deeper extraction and concentration of volatile alcohol impurities on the plates of the column equipment of the Distillation/Rectification Unit.

In the columns of the Distillation/Rectification Unit simultaneously with the release of volatile alcohol impurities due to the esterification reaction is the formation of organic compounds that degrade its quality and reduce the yield of the final product. Thus, during the interaction of alcohols, acids, and aldehydes, the breakdown products of amino acids, sulfur compounds, and other components of the brew in the fermentation column are the formation of esters, aldehydes, and acetals of organic acids.

The aim of the work was to determine the optimal technological modes of distillation of alcohol-containing intermediate products and by-products of the distillation/rectification process in the accelerating column, epuration of wash distillate in the epuration column, the concentration of rectified alcohol in the alcohol column, and its repeated epuration in the column of final clearance, under which the content of organic impurities in rectified ethyl alcohol would be the lowest.

Materials and methods.  Research methods were analytical, chemical, physico-chemical with the use of instruments and research methods used in the production of rectified ethyl alcohol. The concentration of volatile alcohol impurities was determined on a gas chromatograph with a column of HP FFAP 50 m × 0.32 m. It is determined that to increase the degree of extraction of organic impurities it is necessary to ensure the concentration of ethyl alcohol in the column bottom of the accelerating column, which does not exceed 4% vol.; pasteurization zone in the rectification column increase to 10 plates, reduce the concentration of ethanol in the epurate to 22-29% by hydroselection of impurities; for hydroselection in the epuration column use free of impurities bottom products of the accelerating column. To improve the quality of rectified alcohol and reduce energy consumption by extending the contact time on the plates of steam and liquid, a promising direction is the use of mass transfer equipment of cyclic mode. The proposed measures require constant monitoring of technological parameters and provide for the operation of technological equipment in an automated mode.

Published: June 2021

Local anaesthesia is a vital skill and a requirement for most dental procedures. One of the widely used techniques in local anaesthesia is the inferior alveolar nerve block (IANB). Appropriate training is essential for dental undergraduates to mitigate risks and develop the ability of students to learn skills of local administration prior to the care of patients. Due to this issue, an innovative local anaesthesia simulator kit has been developed as a considered new teaching aid in pre-clinical IANB training. Hence, the main objective of this study is to explain students’ attitudes towards the new teaching aid using simulator kit called Local Anaesthesia Simulator Kit (LASK). Dental undergraduates from Year 3 were recruited in this cross-sectional study. The perceived attitudes of students towards the intention to use LASK were reported in this study using descriptive statistics. Overall, the majority of students have a positive attitude towards LASK. More than 75% of the respondents had positive attitudes towards the intention to continue using LASK because its benefits offered and ease of use of LASK. In conclusion, effective and efficient techniques for the administration of IANB in dental procedures, particularly at the undergraduate level, remain crucial.

Published: June 2021

Globally, local anaesthesia is a vital skill and part of the undergraduate dental curriculum. The inferior alveolar nerve block (IANB) is the most frequent regional anaesthesia techniques employed in dental procedures. However, this technique has been reported to have high rates of failure among dental undergraduates and interns. The Local Anaesthetic Simulator Kit (LASK) has therefore been developed. The main objective of this study is thus to examine factors concerning the diffusion of innovation attributes on students’ attitudes towards innovative teaching aids using simulator kit. A cross-sectional survey was performed using a questionnaire, and distributed to dental undergraduates. The items of survey question have been adapted from previous studies. A total of 150 data were valid for data analysis. Respondents were Year 1 and 3 dental students, involving 80% female and 30% male. The study findings reported that the attributes including relative advantage, complexity, compatibility, observability and trialability significantly influence attitudes of students towards the new teaching aid for local anaesthetics. However, there is no statistically significant relationship between complexity and the outcome variable. This empirical study may contribute greatly to the formal instructional significance of dental undergraduates, particularly in the clinical competence assessment at a more microscopic level.

Published: June 2021

The main purpose of this study was to identify critical factors that contributed towards business sustainability among Malay women entrepreneurs in Malaysia. The independent variables were resilience and emotional quotient, and the dependent variable was business sustainability. The study focused on Malay women entrepreneurs involved in service sectors such as food service business, tailoring, and others. About 200 questionnaires were distributed randomly to Malay women entrepreneurs in Setapak, Wangsa Maju, Sentul, Keramat, and Kampung Baru. However, only 110 questionnaires were received and 100 were usable for the study. The data was analyzed using the SPSS software to test for reliability of items and relationships between the independent and dependent variables. The findings revealed that there was no relationship between Malay women entrepreneurs’ Emotional Quotient and business sustainability during the economic crisis. Interestingly, there was a positive and significant relationship between EQ and resilience among Malay women entrepreneurs.  This implies that Malay women entrepreneurs in Malaysia were highly resilient to ensure that their business was sustained during the economic crisis.  Hence, both EQ and resilience of women entrepreneurs need to be enhanced to promote business sustainability during the economic crisis.

Published: June 2021

In this study a technique for a centralized fault monitoring and detection in Gigabit-capable Passive Optical Network (G-PON) using fiber Bragg grating (FBG) sensor is proposed. The technique detects fault once it occurs at the vulnerable locations in the fiber optic distribution link by the proposed FBG devices. Monitoring signal in the C-band is reflected by a uniform FBG with different Bragg wavelengths and reflectivities. The FBGs serve as branch identifiers in the network. The reflected signal from the FBGs is analyzed at the Optical Line Terminal (OLT) in the Central Office (CO) by an Optical Spectrum Analyzer (OSA), to identify the branch with rupture in the network. The simulated result obtained shows that the system can monitor, and detect a fault in the physical layer of the optical distribution network with negligible effects on data signal transmission.

Eserlerinin araştırma kapsamında verimli denklemler oluşturması ve hakkında yazılmış kısıtlı literatüre katkı yapılması gereği Sâdullah Ağa’nın eserleri incelenecek besteci olarak seçilmesinde belirleyici olmuştur. Makalede bestecinin Zencîr usûlünde ve beste türündeki eserleri biçim yönünden incelenmiştir. Eserlerin usûllerinin, ve güfte vezinlerinin araştırmada sabit tutulmasıyla makam değişkeninin eser biçiminde etki sahibi olup olmadığı değerlendirilmiştir. Eserlerin yüksek doğrulukta veriler üretecek şekilde incelenebilmesi için nüshaları arasından seçim yapılmış veya nüshalar karşılaştırılarak kolektif bir nüsha oluşturulmuştur. Güfte biçimleri, müzik cümleleri ve bu cümleleri teşkil eden yapı birimleri, biçim kurguları ve vezin yerleşimleri araştırılmıştır. Sonuç olarak bestecinin üslûbuna dair çeşitli bilgiler Zencîr besteleri kapsamında üretilmiş ve makamın beste biçimine bazı etkileri tespit edilmiştir. Eserlerde kullanılan çeşni ve geçkilerin ana makamla olan yakınlığı azaldıkça bu değişimlerin müzik cümleciği kurgularında genişleme ve özgünleşmeye sebebiyet verdiği, bestelerin genelinde ise makamların niseb-i şerîfeleri (makamsal etki çeşitliliği) arttıkça müzik cümlelerinin kurgularının sadeleştiği, müzik cümleciklerinin benzeştiği anlaşılmıştır. Ayrıca müzik cümleciklerinin başlangıç ve bitişlerinin Zencîr usulünü teşkil eden usûllerin bağlantılarına konumlandırılmasıyla geçkiler oluşmasının önlendiği ve usûle özgün bir nitelik kazandırıldığı görülmüştür.

The purpose of the article is to determine the role and place of UN international legal acts in the formation and development of legal support for combating trafficking in human beings, followed by the publication of the results obtained. This will facilitate the process of adapting the national legal system to the requirements of international treaties to which Ukraine is a party. It has been found that international legal acts in this area can cover almost all countries of the world, as well as only a number of states in a certain part of it. The first acts are adopted mainly by the UN General Assembly, or, for example, the International Labor Or-ganization, which, although it was formed before the UN was founded, but is now its specialized Agency. The analysis of the content provisions these documents allowed us to determine the impact of each of them on the formation of the legal framework for combating trafficking in human beings. Special mention should be made of the Convention for the Suppression of the Traffic in Persons and of the Exploitation of the Prostitution of Others of 1949 and the Protocol to Prevent, Suppress and Punish Trafficking in Persons Especially Women and Children of 2000. The 1949 Convention has been found more to address sexual issues rather than trafficking in human beings. The Protocol today plays a key role in the development of legal support for combating trafficking in human beings, as it provides a definition for this phenomenon that is now reflected in other later international treaties, as well as national legislation of various countries, although with some comments. This Protocol provides for a systematic approach to many issues arising in the work of of law enforcement and other authorities, as well as during cooperation in countering this transnational crime. The obtained and published results can be used by scientists in further research in this area, as well as law enforcement officers in the combating human trafficking.

The purpose of the article is to study the genesis of national legislation in the field of operational investigative activities in independent Ukraine, with the subsequent identification of conceptual problems, as well as the development and publication of proposals to address them taking into account the experience of post-Soviet countries. It is established that the process of formation and becoming of the legal basis for the work of operative subdivisions of authorized state bodies is not complete and it must be continued, as there are problems even with definition of conceptual bases of such activity, in particular related to the requirements of current legislation regarding its grounds. It is a question of whether the operative subdivisions should initiate operative-investigative cases and conduct operational investigative activities or send materials about preparations for a crime to the pre-trial investigation body, except for minor gravity, that is, about crimes being prepared, as well as persons preparing crimes. To solve the problem, we propose to discuss amendments to article 6 of the Law of Ukraine «On operational investigative activities», which would exclude from the list of grounds for conducting for operational investigative activities such as the availability of sufficient information obtained in accordance with the law, requiring verification by means of operational investigative measures, about crimes being prepared, as well as persons preparing crimes. At the same time, information about crimes being prepared, as well as persons who are preparing crimes, should be immediately entered into the Unified Register of Pre-trial Investigations, except for minor ones, and preparation for a crime should be investigated immediately by an investigator. This model is more consistent with the work of Western law enforcement agencies, but, as the study showed, is not typical of post-Soviet countries. These proposals, as well as alternative ones, on the harmonization of operational investigative and Criminal procedure legislation require professional discussion, but changes in one form or another are inevitable. The obtained and published results can be used by scientists in further research in this area, as well as law enforcement officers in the conduct of operational investigative activities and crime investigations.
Forensic description as an element of the methodology of investigation of criminal offenses against morality
Authors: Yefimov Mykola
Published: June 2021

The scientific article is devoted to the study of some aspects of the investigation of criminal offenses against morality. Peculiarities of forensic characteristics as an element of the methodology of investigation of this category of criminal offenses are considered. The author emphasizes that any method of investigating certain types of criminal offenses has a certain structure, an important element of which is the forensic characteristics. The concept of forensic characteristics as an element of methodology, quantity, content and significance of structural elements of this scientific category remain vague and contradictory. Moreover, at the turn of the millennium, the question of the expediency of the existence of forensic characteristics as a scientific category in general became acute. Therefore, it should be borne in mind that the value of forensic characteristics can be divided into practical and theoretical. For police officers who are directly involved in the investigation, the most important thing is the practical application of a tool that will help in the investigation process. It is noted that the method of investigation of certain types of criminal offenses is a system of sci-entific provisions, as well as methodological and practical recommendations developed on their basis for the investigation of certain types and groups of criminally punishable acts. It is emphasized that the structure of the studied scientific category is as follows: forensic charac-teristics of criminal offenses; analysis of primary information and initiation of criminal proceedings; cir-cumstances to be proved in criminal proceedings; typical investigative situations; features of conducting initial investigative (search) actions, covert investigative (search) actions and other measures; features of further investigative (search) actions, covert investigative (search) actions and other measures; features of the use of special knowledge during the investigation of a criminal offense; preventive activities of the investigator in relation to the causes and conditions that contributed to the commission of a criminal offense; features of the investigator's activity at the final stage of the investigation.
