The Potential of Online Workouts for Fitness Trainers
49-60Views:593The importance of physical activity for both physical and mental health is unquestionable. For leisure athletes, fitness clubs can be considered as popular facilities for everyday workouts. Classes run by qualified trainers, whether individual or group workouts, are very popular. In line with the worldwide trend, there is a growing expectation for fitness workouts to be reachable as simple as possible, in as many forms as possible, regardless of the location. The aim of our study is therefore to map the prevalence of online training among trainers working in the fitness sector. There is a significant demand for such workouts, even if it cannot completely replace hours of personal presence. In addition, as well as for target groups who want to find a form of exercise that can be performed anywhere, anytime, the online space provides an ideal opportunity to practice regular physical activity, as well as a good opportunity for coaches to expand their clientele and services.

Survey of population knowledge on the technical characteristics and physiological effects of light pollution in two settlements
155-161Views:292One of the newest environmental challenges in our industrialized world is light pollution. It means that we emit more light than necessary, and this is often done at wavelengths that are both disturbing and even harmful to human health. The Dark Sky Parks, where over a large area there are no artificial light sources that burden the environment. One of these parks is located in BAZ County, near Répáshuta, and is under continuous development. Our study reports on a questionnaire survey conducted in Répáshuta, which is informed about light pollution, and in Cserépváralja settlements close to it, but without direct knowledge of the problem. The population of both villages is around 400. With a direct on-site survey, we asked 21-21 questions to 30-30 person and received answers in all cases, of course, taking full account of the anonymity of the respondents. Recruitment took place in March and April 2019.

Wearable technology usage among students of the University of Debrecen
33-47Views:371The lack of physical activity and the growing prevalence of a sedentary lifestyle are urgent public health problem worldwide. The problem is also typical of the young population, especially university students, who spend most of the day in a sitting position. Technological development is one of the catalysts for the rise of a sedentary lifestyle, nevertheless, thanks to this, many devices have appeared on the market that can be used to encourage physical activity. The widespread of wearable activity tracker devices – wristwatches, wristbands – among the population shows a constantly increasing trend, with a parallel increase in the amount of data collected about ourselves (step count, calories burned, heart rate). The main goal of the present study derives from the recognition of the gap in this field in the domestic sports science literature therefore our focus is on modern information technology tools in the dimension of physical activity. The aim of this study is to assess the attitudes of the university student population towards activity-tracking devices. We conducted a cross-sectional online quantitative survey (questionnaire) among DE GTK students. 340 people filled out the questionnaire correctly. In addition to descriptive statistics, parametric and non-parametric tests (Pearson's chi-square test, Fisher's exact test, t-test, Mann-Whitney test) were used to examine the relationships. The results of the statistical tests were considered significant if p<0.05. We performed the distribution of the variables using the Kolgomorov-Smirnov test. The majority of respondents (55%) have already tried some kind of wearable device that measures physical activity. Every third student (34%) are currently using their device. Those who have not tried these devices so far indicated the price as the primary deterrent. 32% of the students plan to invest in such a device in the future. 39% of device users use an activity tracker bracelet, while 61% use or used a smartwatch. In terms of sex, we did not find any differences in asset ownership. The primary goal of the students (66.8%) was to track their physical activity. The most frequently used function was tracking the number of steps, indicated by 81% of the respondents, followed by heart rate measurement (67%). Most of them (69%) set some kind of goal regarding their number of steps. According to every third student, they moved more as a result of the device and managed to maintain the increased level of physical activity. 44% of the students claimed that their physical activity did not change despite using the device. Students tend to disagree with the positive statements related to the devices in connection with a healthy lifestyle. Although the present study suggests that wearable devices have an impact on students and they track their measured data, it is questionable whether the devices themselves are enough of an incentive for students to develop a healthier lifestyle.

Mechanical Design and Finite element Analysis for Acetabular cup
23-35Views:319Hip replacements typically consist of a four-part piece. Our research will focus primarily on the acetabular component. Several different types of materials can be used when creating a hip replacement implant ranging from plastic to titanium. Different materials are used to accommodate for allergic reactions or circumventing potential health risks. Aside from the material, the size of the components plays a factor in terms of durability; a larger diameter head might avoid dislodgement though it could increase wear and tear on the stems through constant friction. A patient’s force applied to the hip replacement is usually measured through a number of physical assessments. Finite element analysis (FEA), a computer-based method of data observation, allows for us to accurately simulate hip forces and their impact on the hip replacements. Through this, it becomes easier to predict and calculate the performance of specific designs. Generative systems can also be used to support performance analysis and optimization through assessing a multitude of cases, many of which apply in real-world scenarios. By applying both systems, we designed and modeled an acetabular cup that when measured decreased the mass from 129 grams initially down to 52 grams, a 60% decrease in total mass. Furthermore, the design we created lessened the trauma on the piece through distributing force across the entirety of the piece rather than specific segments only. This shows an increased durability and life expectancy when compared to usual acetabular cups.

The Role Of Leader In Work Addiction
85-97Views:449Over-attachment to work is an increasingly common phenomenon in the lives of people in organisations, and can also be a condition of work addiction. Whoever becomes involved in an organisation, be it a subordinate or even a manager, work addiction has a number of negative consequences at both individual and organisational level. Without being exhaustive, work addiction can have an impact on organisational performance, organisational effectiveness, workplace conflict, career prospects, health maintenance. In this paper, we aim to highlight the most relevant publications from the last five years to report on the impact in an organisation when work addiction arises among subordinates or managers, and how different leadership styles are associated with work addiction among organisational members. The publications were retrieved from Google Scholar and Scopus, and the results of 19 articles are presented in this paper after a review of 263 papers retrieved. The results show that transformational, servant and ethical leadership styles have ambiguous effects on work addiction, unlike laissez-faire or abusive leadership styles, the former enhancing and the latter reducing the incidence of work addiction in an organisation. Work addiction of managers also has a dual effect: on the one hand, it can enhance creativity, but it can also increase turnover among subordinates. Social support from the manager can be an antidote to subordinates' work addiction, but this effect may be modified by the quantity and quality of interaction between manager and subordinate, the sense of meaningfulness of the work, or even the organisational culture. Overall, the manager, as a key actor, can have an impact on work addiction in the organisation, but there is not always a consistent position in the research on the cases and the way in which this is done, which calls for further research in the future.

Requirements for Multicultural Competencies Defined by a Focus Group
44-56Views:361Globalization, the spread of multinational companies and the enormous development of information technology can lead to a new trend in employers’ requirements. However, being employed by an international company is a real possibility for any employee in any part of the world. Even if they do not have to work abroad, employees may have to function in a multinational environment in their home countries. A favourable combination of intercultural competencies is a key factor in the selection and development of employees. A possible way of measuring these competencies can be the Multicultural Personality Questionnaire (MPQ). First of all,on the employers’ part, it is important to clarify the exact requirements and competencies (dimensions) to be able to draw up an ‘ideal profile’. We prepared two versions of the MPQ (91-item; 5-dimensional) and used them to test employers’ requirements in the selection process regarding the dimensions of cultural empathy, open-mindedness, social initiative, emotional stability and flexibility. This study describes the results of a focus group interview, which took place in 2017, revealing the importance of multicultural competencies from the employers’ point of view and examining the conditions of the adaptability of the two questionnaires. We used the focus group method to find out in what conditions the questionnaires canbe used in a selection process. What possibilities and limits are therefor using the direct five-dimensional questionnaire? What aspects do we need to take into consideration in expressing and interpreting the requirements in the results of the test?

Determination of the accumulation of heavy metals of river sediment by plants
46-53Views:266Danube is the main river of Hungary. Danube and its floodplains and oxbow lakes are operating as ecological corridors, although their industrial, logistic and touristic role is not negligible. It is well known, that from the source to the estuary of the river Danube there are many industrial facilities. This heavy industrial pollution had effected on the water quality. The most dangerous components of the sewage water of these facilities are heavy metals, which can be found in the water as well as in the sediment. These toxic elements can cause significant health risks, because they can accumulate in the food-chain. The main aim of our research is to investigate the accumulation rate of the heavy metal content of the river sediment in the different parts of the test plants. The main sampling place of our research was a sediment dump was created by excavation from the Open Beach of Dunaújváros in 2009. During our measurements we analysed the cadmium, nickel, lead, chromium, copper and zinc concentration of the sediment and the plants. The test plants, which are growing on this sampling place, were parella (Rumex patientia), perennial rye-grass (Lolium perenne), sedge (Carex riparia), bistort (Persicaria maculosa). The extraction of the heavy metal content of the samples was made according to the MSZ Hungarian standard. The concentration of heavy metals were analysed with AAS (atom absorption spectrometer). According to our results we determined that parella could accumulate cadmium, nickel, chromium and zinc in its upper stem, on the other hand bistort could accumulate these elements mainly in its leaves. These information will be important in the case of the in-situ remediation of a polluted area in the future.

The presence of stress and leisure sports in the life of today’s people
74-86Views:983Today's people are extremely busy with a lot of things, such as work, family, learning, so they try to spend their free time with activities that promote them in relaxation, reassurance, recreation. It can be said that the people of today's world are burdened, more stressed and nervous, trying to do the best they can to live properly. A lot of people have a hard time communicating, community life. There are a lot of people who are forced to work from home, as projects and weeks' deadlines don't wait. Besides, there are many things to be done, children need to be dealt with, you have to have fun, you have to pay attention to health, you have to run a household, etc., so there is little time for people to do what they really love. In my research, I assessed the leisure habits of the inhabitants of Romania and Hungary, but their attitude to active reclamation activities (N=273) was their activity in sport. The results show that passive leisure activities (watching TV, reading, listening to music, internet) are still the most popular among people, although most of us do sedentary work. People who play sports in their spare time felt more refreshed, and they had a better mood, more positive. The sports that people can play outdoors and in parks come to the fore.

Combustors with Low Emission Levels for Aero Gas Turbine Engines
503-514Views:711The aircrafts are responsible for emitting several types of pollutants, especially the pollutants in the form of NOX, CO2, CO, UHC, SOX and Particulate Matter PM (smoke/soot). The impact of aviation emissions on the global is well known, where these emissions modify the chemical and microphysical properties of the atmosphere resulting in changes of earth’s climate system, which can ultimate in critical changes in our planet fragile ecosystem, also the pollutants produced by aircraft engines cause many health problems. This is why the International Civil Aviation Organisation (ICAO) is seriously seeking to control the emission levels by issuing new standards during the successive meetings of the Committee on Aviation Environmental Protection CAEP (CAEP/01 in 1986, CAEP/2, CAEP/4, CAEP/6, CAEP/8, etc). The new regulations include more stringent standards aimed to reduce emission levels, this led to increased interest in low emission technologies. In this paper, a comprehensive review of low emissions combustion technologies for modern aero gas turbines is represented. The current low emission technologies include the high Technologies Readiness Level (TRL) including RQL, TAPS, DAC and LDI. Also, there are advanced technologies at lower TRL including LPP, ASC and VGC.

COVID-19 Pandemic Impact on Employees’ Physical Activity
72-84Views:983Globalization and the recent explosive development of technology have significantly changed people’s lifestyles resulting in an increase in the number of people living a sedentary lifestyle. COVID-19 pandemic has exacerbated the situation and created an unprecedented situation in the world. In the present study, we investigate changes in the physical activity and sedentary behavior of adult workers caused by the coronavirus epidemic. In our online cross-sectional research, we used snowball methodology. The target group of the survey was adult workers. 108 people filled in the questionnaire, the majority (73.1%) are women, the average age is 37.18 years and most of them have higher degrees (Diploma: 74%, PhD: 14%). The present study revealed a decrease in physical activity and an increase in sedentary time for the employees in our study. Despite respondents detected a decrease in their physical activity, an increase was reported in the proportion of online training participants. The majority of respondents partially, or totally switched to work from home during the pandemic, which may further increase their sedentary lifestyle. We did not find significant differences among the domain of work and leisure time or occupational physical activity patterns. The workplace is a great opportunity for promoting physical activity and reducing sedentary time in the adult working population, therefore it would be important for organizations, decision-makers and health professionals to work on the design of strategies to these goals.
