Classification of Nanomaterial’s Risky Properties on the Aspect of Human Safety
34-45Views:365Due to their unique properties the application of nanomaterials continuously extends thus these appear for several industries. The industrial application of nanomaterials became significant during the last decades. As a result of the intensive development, our knowledge about the exact influence of nanomaterials for living bodies and human health is characterised by deficiency for both short and long time. Nanomaterials able to be entered to the living organism through several ways then invade to the circulatory system and the lymphatic system, reach the organs and can induce various kind of damages and serious diseases as a result of their different appearance, physical and chemical properties. Legislation in Hungary and in the European Union seems to be incomplete. There is no document which summarizes and details the risky factors and parameters in case of a risk assessment. Our aim was to develop a criterion system considering the risks related to the use and contact of nanomaterials based on their physical, chemical and biological properties, which criterion system could provide basic principle for a risk assessment thereby make the industrial processes safer both for the employees and those who are in the vicinity.

The Information Security Risks of the BYOD
176-185Views:404Today we cannot imagine our everyday lives without using our smart devices. While commuting we often get into people - even literally - who are doing their work on their portable devices 24 hours a day. This habit is widespread; there are many solutions that can be used by the corporation to have their employees work on their private devices, besides using it in their personal life. They can use these devices at their home, while commuting, or even while being at their own cubicle at the firm. In this article, we are concentrating on the IT risks of the firm with this work practice from a theoretical point of view. After this step, we will continue our research with investigating the problem of measuring and mitigating of these risks.

Transportation System of Major Cities in the Middle East
50-53Views:342The quality of transportation has a great effect on the quality of our everyday life and the future of our planet. In contrary to Europe, transportation culture of the big cities in the Middle East region has grown fully different way. These Middle Eastern cities tend to have a different historical, traditional and structural background compared to other cities all around the world. One of these big cities is in the focus of our paper: Rijad, with 6 million inhabitants is the archetypal car dominated city of the Arabic world. We also elaborated a comparison to 4 other cities: Dubai as a city similar to Rijad, Amsterdam as a city with a modern green attitude, Budapest as a metropolitan city in Hungary and last but not least Debrecen which is a Hungarian city with moderate population. As a lesson learnt, we try to give some possibilities and outlooks for Rijad, in order to improve the structure of transportation.

Investigation of Parental Roles in Relation to Youth Football
105-114Views:422My research is based on the fact that, thanks to the development of sports and the capital flowing into the sector, youth sports are no longer just a useful way of spending free time for children and a mean for educating them for a healthy lifestyle, but also an opportunity to lay the foundation for an adult sports career and, with it, secure future existence. In order for the training to be effective and productive, one of the many components is the existence of parental support. Youth competitive sports pose many challenges for a family and influence their lives from several aspects. In my research, I examined how youth sports affects parents in terms of certain demographic variables, what changes it generates in their family life, and I also paid attention to what expectations the family has about sports. The basis of the study is an online questionnaire survey, which was filled out by more than 700 parents of youth football associations. My research revealed that, in accordance with the previous literature related to the topic, their children's sports have a significant impact on the lives of the parents and they set different expectations regarding it, which are also influenced by various social and demographic factors.

Examining the Social Involvement of Sports Civic Organizations
23-34Views:380Analyzing the information available in the Hungarian database of the CSO, we can see that a significant part of the income of classical non-governmental organizations, especially non-governmental organizations with a sports profile, comes mainly from state or private support. In addition, it can be said that these organizations are essentially non-profit-oriented and play a significant role in social integration and the performance of essential social tasks. Therefore, the relevant question is to what extent and in what way their social embeddedness is realized, in what way do NGOs influence people in the course of their operation? Within this, the study of the social usefulness of sports non-governmental organizations and the sphere of support conditions in the sphere emerges as a priority area. In our study, we undertake to examine the activity of the organizations included in the survey, their social impact and to compare the results with their role in local society. Nearly 50% of the NGOs surveyed in the study have a local scope, and more than 50% typically engage in grassroots and leisure-related activities.

Studies on Consumer Motivation Among Users Of Fitness Services
442-453Views:502The rate of inactivity experienced world-wide is the cause of numerous health problems. The sedentary lifestyle of the population represents a great burden to a nation’s economy. The health indicators of Hungary are below the European average, not only those concerning physical activity, but also with respect to smoking, nutrition, and alcohol consumption [1]. In 2013, only 38% of the Hungarian population exercised regularly, while 62% rarely or never [2]. The diseases associated with inactivity represent a higher burden to the economy than the costs of raising the level of activity would be [3]. Based on previous studies, the motivating factors for leisure athletes in Hungary are the preservation of health, to increase physical strength, relaxation, recreation, the love of exercising, and stress management [4; 5]. The sports facilities available to a wide range of people, the fitness clubs offer the possibility to join regular sports activities, which is why it is necessary to examine the motivation behind the participation of athletes taking part in the trainings provided by fitness facilities. Many previous studies examined the goals of athletes and the motivational factors behind exercising, and came to the conclusion that trainings held in fitness rooms and at home are related to intrinsic motivational factors, while taking part in other sports activities are related to intrinsic motivational factors [6; 7]. The focus of my study are leisure athletes using the services provided by fitness clubs (753 people), of whom I evaluated the motivational factors behind taking part in trainings. The results show that the motivational factors driving consumers of fitness services show a ranking that is identical to those of other leisure athletes, with most of them taking part in fitness trainings in order to preserve their health, to improve physical strength, and for recreational purposes, while the improvement of physical appearance also plays an important role.

Bread Making and Consumption Habits in the Gluten-free Diet
252-262Views:521Celiac disease is a genetic autoimmune disorder characterized by sensitivity to gluten. Gluten is a protein found in many grain products (wheat, rye, barley and oat). When a person with celiac disease consumes gluten, his/her immune system perceives the gluten to be a harmful substance and reacts negatively. The only treatment for people with celiac disease is lifelong adherence to a gluten-free diet. Bread is a basic and frequently consumed food made from basically gluten-containing grains. Bread plays essential role in the Hungarian dining habits, thus bread consumption in the gluten-free diet is a challenging question. The aim of our empirical research was to investigate the gluten-free bread making and consumption habits of people following a gluten-free diet.

Egy hazai vállalat szervezeti magatartásának vizsgálata, különös tekintettel a motivációra
206-216Views:1050A XXI. században a globális versenyképesség jelenti a vállalkozások számára az egyik legnagyobb kihívást. A vállalkozásnak magas színvonalú és kiegyensúlyozott működést kell megvalósítania ahhoz, hogy meg tudjon felelni a globális kihívásnak. A cégeknek erre a jelenlegi helyzetre kell minél hamarabb jól működő stratégiát kialakítani, mielőtt az összes tehetséges szakmunkás külföldre vándorolna a jobb remények érdekében, még nagyobb munkaerőhiányt okozva ezzel a piacon. Tanulmányunk célja az volt, hogy a vállalaton belül megvizsgáljuk a szervezeti magatartást, illetve a motivátorokat, és javaslatot tegyünk a fejlődési lehetőségekkel kapcsolatban. A szervezet elemzéséhez először a szervezetben dolgozókat soroltuk be a generációs elméleteket alapul véve. A baby boom generáció számára motiváló tényezőként jelenik meg a magas munkabér, a növekvő béren kívüli juttatások, a jó munkatársi kapcsolatok, illetve az önálló munkavégzés. Az X generációnak is a magas munkabér és a jó munkahelyi kapcsolatok a legfőbb motiváló tényezők, illetve a modern technikai berendezések. Az Y generációt leginkább a jó munkahelyi kapcsolatok, a magas munkabér, valamint a béren kívüli juttatások növelése ösztönzi. A cégnél dolgozó legfiatalabb generáció szinte hallani sem akar a felelősségi kör bővítéséről és az előléptetési lehetőségről. Számukra is meghatározó a biztos munkahely.

The Empirical Examination of Different Customer Types
92-100Views:325The proper knowledge of customer types is essential for a well functioning company – regardless of its size. In current research we wanted to identify and characterize the particular customer groups with involving 302 persons. During the examination we measured the attitudes of these participants with the help of a statement range based on Kotler’s classical customer types. For the identification we made factor- and cluster analysis, and we could separate five different factors. They received the names of Angry, Definite, Discursive Passive, Experience Shopping and Indefinite - based on some related statements. After the cluster analysis – along these factors - we could separate four different groups: Young Impulse Shoppers, Outspoken Definites, Negatives and Born Customers. Each and every group requires different communication, sales attitude and service morals.

Opportunities for Keeping Talent Highlighting Career Needs
31-43Views:638Organizations should focus not only on finding a workforce, but also on finding a talented employee and to be able to keep them. That is why we considered it important to pay attention to talents and careers. In this paper, we attempt to identify those factors which are important for career prospects among future employees and those already in the workforce. Moreover, we want to identify the factors which those who are already employed consider to be factors influencing their career prospects. We conducted a survey of students using questionnaires. 116 questionnaires were completed, of which 73 were filled in by BSc / BA students and 43 by Msc / MA students. We sought to discover to what degree the respondents considered the career factors we presented them with as influencing their ability to acquire an ideal job, as well as to what degree the same career factors would be able to assist them in their future career advancement. Presently, in their roles as students seeking gainful employment, important factors include perseverance, diligence, knowledge, and aptitude, all of which the respondents feel will become even more important in making their later advancement possible. At present, they do not consider the support of companions / partners and morality important; but they consider the support they receive from their colleagues to be a factor which grows in importance over time. In the questionnaire survey of employees, we were looking for two answers. On the one hand, which factors are important in shaping their careers, and on the other hand, at the workplace, which factors were related to employee retention and satisfaction. For their careers, they consider it important to have diligence, morality, and the support of colleagues. These results are similar to the views expressed by the students. However, those who already work consider ‘kissing up to the boss’ to be more important for their advancement possibilities than the students did. The responses concerning factors contributing to successful employee retention brought interesting results. Factors that are most commonly fulfilled, such as a good co-worker relationship and the working relationship with a leader, are barely above the average score of 4, which is actually a result that is above average. Medium results include the realization of independence, challenging work, fair pay and career prospects factors, all of whcih would be vital for talented people to experience flow in their careers. In the long term, leaders and HR professionals need to pay attention to take calculated, equisite steps to keep talented workers.

Analysis of Social Media Activities - Through the Examination of Handball Clubs Competing at Different Levels
39-53Views:660In Hungary, handball enjoys special attention and support, this is true not only for our country, but also for Europe, and the sport is gaining more and more space worldwide. One of the biggest innovations of the last two decades is certainly social media, which has reformed the basic strategies related to information transfer and traditional marketing activities. The processes of content production on these platforms have radically changed, which every sports club should pay attention to, as they can gain significant advantages in terms of economics, marketing and community building if they are able to communicate well. Three sports clubs competing at different levels were compared during a qualitative study in terms of their social media marketing strategy activities, namely PICK Szeged, Balatonfüredi KSE – BFKA Balatonfüred and DEAC handball team. The basic concept of this research model was built on how the online marketing communication activities of club teams fighting for different professional goals at different levels differ from each other, as well as what are the development opportunities and aspects that can be used as effectively as possible on social media platforms. The handball club teams agreed on several research questions, but a significant difference could also be discovered in one area, in which the professionals responsible for social media disagreed or represented a different point of view. Looking at my results, it can be concluded that behind a successful online marketing strategy there is always serious preparation and planning work, as well as the diversification of content production on different platforms, because the consumer communities of the platforms are also different from each other.

Investigation of the Resistance Force Acting on a Sailing Craft in the Case of a Change of Draft Caused by a Change of Powertrain Using Numerical CFD Simulations
30-35Views:414Nowdays In the case of recreational craft, interfering with motor drive solutions is a common workflow due to increasingly strict rules for environmental reasons. When switching from an internal combustion engine to an electric engine, the change in draft varies from boat to boat, but it can be said in all cases that as the mass changes, so does the draft. Because of this, the magnitude of the resistance force acting on the ship also varies. In this paper, we examine, through a specific example, the benefits of a change in dive caused by weight gain at different travel speeds.
