Analysis of Social Media Activities - Through the Examination of Handball Clubs Competing at Different Levels
39-53Views:531In 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.

Determination of the accumulation of heavy metals of river sediment by plants
46-53Views:225Danube 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.

„Return to the Countryside” – The Retention Possibility of the Sport
292-307Views:495Nowadays, one of the most interesting parts of sociology is the research of the rural areas’ specific features. Within these studies the rural areas ability for survival and to retain forms an important basis. A basic pillar of these, that the youth from these areas become sufficiently motivated to return to their rural homeland after finishing their studies and be able to redound the local social and economic development. Sadly, we experience the opposite of it. Young generations are fleeing to large cities and in medium or long term it leads to the decay of these involved settlements; in worst case scenario the results can be irreversible. In close relation with the aforementioned, we have to mention the specific behaviour of the local – rural – elite, which can be the source of further problems. In the course of our research, we wanted to investigate, that what is the reason that university students, who are studying in large cities don’t want to return or move to rural areas. Furthermore, we tried to give an inside view about their opinions of rural areas and the life in the countryside.

Proposition of Enhancing the Significance of Green Infrastructure in the Smart City Concept
1-22Views:358The aim of the paper is -in accordance with the goals of the research team called „ Sustainable Integrated Settlement And Regional Planning” within the project EFOP-3.6.1-16 – to compile a comprehensive expert material on smart city. In accordance with my personal assignments within the teamwork, I studied first of all how sustainable urban water management issues are managed in the corresponding smart city documents, how the smart city concept which is evidently one possible way of sustainable urban development involves the strategy of sustainable stormwater management along with the elements of green infrastructure which are the inevitable segment thereof. The basis of the study were Hungarian official methodological guides and one university textbook published so far in the topic. Contrarily to the expected results the two notions of smart city and sustainable urban water management are not harmonized despite their common overall goals. Therefore I make a few suggestions in order to harmonize to some extent the criteria and indicators developed for the two notions - smart city and sustainable urban water management including green infrastructure - promoting sustainable cities. The overall goal is to ensure that green infrastructure is not neglected while smart cities are realized.

The presence of stress and leisure sports in the life of today’s people
74-86Views:898Today'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.
