BIG DATA AND DECISION-MAKING SUPPORT
No full textINTRODUCTION: Nowadays, Big Data is created in previously unimaginable quantities. Newly generated data from various Internet of Things (IoT) sensors and their use have never reached their current dimensions. Along with this trend, the availability of devices capable of collecting this data increases, the time for their evaluation is reduced and the volume of data collected at the same time increases. The most important task of research and development in this area is to bring solutions suitable for processing large amounts of data because our current storage and processing capabilities are limited and unable to compete with the storage, processing and publication of the resulting data.
OBJECTIVES: Point out the importance of implementing Big Data technology.
METHODS: To achieve the goal, the following methodological approach was chosen: study and processing of foreign and domestic literature, acquaintance with similar solutions for data processing, definition of Big Data and IoT, proposal for using Big Data solution to support decision-making, risk definition and evaluation.
RESULTS: With the growing amount of disparate and incoherent data and the further growth of the Internet of Things, it is now almost impossible to evaluate all available information correctly and in a timely manner. Without this knowledge, the company loses its competitive advantage and is unable to respond in a timely manner to client requests.
CONCLUSION: Implementing a solution for processing Big Data to support decision-making in the company is a complex process. As part of the implementation and use of the Big Data solution to support decision-making, the company must be prepared for the emergence of various problems. We can assume that Big Data technology will constantly be evolving in terms of streamlining analytical tools for obtaining information from large volumes of generated data. Therefore, it is appropriate to create space for the implementation of Big Data technology
TRANSPORTING OBESE PERSONS USING AN EVACUATION PAD
No full textObesity is not only a medical illness but also a cosmetic problem. Obesity can be defined by the BMI index, which is not very accurate. The ABSI index, which includes BMI, the person’s waist circumference, and their height may be used to more accurately determine obesity. Time is very important in saving people's lives, especially in emergencies. The rescue time for obese people is even longer — often much longer — than for other disabled people. This is because more rescuers are needed, problems arise when they have to go through the door or go up and down stairs. For the evacuation of obese people, evacuation pads located under the mattress are often used. Evacuation pads are used, for example, by hospitals or social service homes. Evacuation pads are designed for use by nurses, other emergency staff, or caretakers. In this exercise, four people were used – two nurses and two firemen. To find out the advantages and disadvantages of the evacuation pad, we performed a tactical exercise.
During the tactical exercise, the victim was evacuated by a single nurse, then by two nurses. After that, the victim was rescued by one firefighter and then two firefighters. This research is relevant to aspects of the rescue of immobile obese people with a special evacuation aid. It demonstrates the advantages and disadvantages of an evacuation pad based on actual tactical rescue exercises
METHODS TO DETERMINE COMPLEX DEGREES OF MUTUAL ANISOTROPY FOR THE DIFFERENTIATION OF HEMORRHAGES IN THE HUMAN BRAIN SUBSTANCE RESULTING FROM TRAUMATIC AND NON-TRAUMATIC GENESIS
No full textAn issue that is often debated in forensic traumatology is the differential diagnosis of hemorrhages into the human brain substance (HBS) of traumatic and non-traumatic genesis.
Objectives. This study aims to identify new criteria for objective forensic differentiation of hemorrhages of traumatic origin, cerebral infarction of ischemic and hemorrhagic genesis by using the method of complex degree of mutual anisotropy. For this study native sections of HBS from 125 corpses were used in the case of: death from coronary heart disease - 35 (28%) of native sections (Group 1 - control); hemorrhages of traumatic genesis - 30 (24%) sections (Group 2); ischemic cerebral infarction - 30 (24%) native sections(Group 3); and hemorrhages of non-traumatic genesis - 30 (24%) native sections (Group 4).
Results. The statistical moments of the third and fourth orders, which characterize the asymmetry and excess of the complex degree of mutual anisotropy module size distributions, the strength of the method of polarization-correlation microscopy in the differentiation of the samples of the histological sections of the brain of control and experimental groups reached a good level — 87%-90%.
Conclusion. The method of complex degree of mutual anisotropy allows differentiating with great precision the genesis of hemorrhage into the substance of the brain

SELECTED ASPECTS OF THE INTERNET OF THINGS DURING GLOBALIZATION
No full textContinuous technological progress makes it possible to use the Internet of Things (IoT) in broader dimensions. Digitization, computerization, and innovation are now key factors for businesses and countries to achieve added value and make progress in competitiveness and attractiveness. These are also optimal conditions for the application of IoT. This study aims to show the status of the implementation of IoT in neighboring countries — the Slovak Republic and the Czech Republic — compared to the United Kingdom, which is in the lead. Similarly, the goal was to compare the areas of digitization and informatization to the Networked Readiness Index (NRI), the Digital Economy and Society Index (DESI), and the Digital Transformation Scoreboards (DTS). Material support for this paper was garnered from the relevant literature. The theoretical basis for issues related to IoT was presented after analyzing secondary sources to determine the current state of the industry and the level of digitization. The those indexes were compared using data from Slovakia, the Czech Republic, and the UK. The UK is among the leaders in the field of IoT. The resulting data are presented graphically. Slovak companies that operate mainly in the industrial sector are beginning to discover and implement IoT. More and more cities are adopting this technology. The situation in the UK is already quite far along. During the evaluation of the NRI, DESI, and DTS, Slovakia was ranked lowest, the Czech Republic was ranked slightly higher, and the UK was rated the highest. Comparison of the digitization of the economy and society, and the deployment and use of ICT highlight the need for further development of these areas in the Slovak and Czech republics
BLACK SWAN EVENT: AN EVIDENCE FROM CHINA’S ECONOMICS EFECTS
No full textThe prognosis of upcoming crises and the course of actually understanding them is increasingly becoming a major subject of discussions in pursuit of reliable indicators. The trade war between the United States and China, along with the COVID-19 pandemic are two events that took place in the Chinese economy with the aforementioned characteristics of the Black swan phenomenon, to which this latest professional analysis is devoted. The objective of this research is to examine the response of the Shanghai Stock Exchange Composite (SSEC) index, in addition to its relation with macroeconomic variables contributing towards a possible Black Swan Event. We employ an econometric methodology comprising of a unit root test, descriptive statistics, linear regression and correlation analysis for the period 2007-2019. Our results illustarte that the bubble from 2015, which is classified as a Black Swan event by many researchers, has a negative influence on the SSEC index. We can further deduce that there were some psychological effects on the Chinese stock market that lead to both, positive and negative trends of SSEC indices. The main findings confirmed that the Consumer Price Index, Exchange Rate, Interest Rate, Unemployment, GDP and Trade Balance were significantly elaborative macroeconomic variables, that had a substantial impact on the SSEC index

COMMUNICATIVE TECHNIQUES IN FORIGN LANGUAGE LEARNING IN THE FIELD OF SPORT
No full textThis article presents ideas and models for English language learning, using elements of two communicative learning methods for the specific purposes of sport practice. It is part of a pedagogical experiment, carried out with students from the National Sport Academy “V.Levski”, Sofia, organized into an experimental group (34) and a control group (34). The aim of the experiment was to study the influence of interactive techniques applied in the specialized English language course for sport terminology. The experimental course work involved using elements of different interactive learning methods to teach sport terminology to the experimental group of students for about 30-40 minutes of every academic class of 90 minutes. Initial and final tests of the basic language skills and knowledge of sports terminology were carried out with the experimental and control group of students, in order to establish their language competences before and after the experimental course. The results from the tests were processed with statistical methods – variation analysis and Student’s t-test (dependent and independent samples). The results from the initial and final tests of the two groups have shown that students from the experimental group have improved their language skills, their confidence in using the language and their knowledge of sports terms to a greater extent than the control group. Applying interactive techniques in language learning for the needs of sport specialists leads to better results in their language acquisition
EMOTIONAL INTELLIGENCE AS PART OF THE STRATEGIC DEVELOPMENT AND MANAGEMENT STYLE IN THE PRE-HIGH EDUCATIONAL SYSTEM IN ALBANIA
No full textIn today’s modern world, emotional intelligence (EI) has a strong connection in the work environment and it is considered to be one of the key factors in the well-functioning of institutions, especially of educational ones.
The main aim of this study is to identify, whether the directors of the schools of the pre-high educational system in Albania are aware of the concept of emotional intelligence, are trained and if they implement it in their leading style, in order to achieve an overall success in schools. The study also aims to identify the differences between new and senior principals in using EI.
The research methodology is quantitative, 183 questionnaires were filled in by teachers in 11 different schools of the pre high educational institutions in Tirana.
The instrument used consists of 40 standard statements that cover all five characteristics of the emotional intelligence: self-awareness, self-control, motivation, empathy and social skills, by analyzing the level of agreement in a 1-5 Likert scale.
The study has shown that principals and teachers of the pre high educational system in Albania have no knowledge on emotional intelligence and as a result they do not implement it. The principals do possess some elements of emotional intelligence as a part of their soft skills, but they are not aware of them and do not use them in increasing the teachers’ work satisfaction.
Also, there is no difference in the usage of emotional intelligence between young and senior principals, apart from the fact that the seniors have better developed soft skills. This would help them to come closer to the characteristics of emotional intelligence.
The results of the study imply some recommendations for policy makers, school’s principals and mentor teachers in increasing the use of emotional intelligence in the pre high educational system in Albania. The results confirm the necessity to train the principals about the latest news in the field of education, ethics, communication and leadership with a focus on raising leadership within the focus of Emotional Intelligence. The ministry of Education, Sport and Youth should design policies for the professional development of leaders and teachers in accordance with new management strategies such as emotional intelligence
