  The role of dietary fibre and its impact on health is increasing. It is worth noting that their beneficial effects on the body are becoming more widely known, but their consumption is still below the recommended daily intake from food. Dietary fibre, as a class of compounds, includes a mixture of plant carbohydrate polymers, both oligosaccharides and polysaccharides. Dietary fibre has been linked to a number of diseases, as its consumption can reduce the risk of cardiovascular disease and type 2 diabetes. They influence the composition of the bacteria present in the human gut. Consuming the right quantity and quality of dietary fibre can play a role in the prevention of certain types of cancer. Nowadays, it is common to produce various fibre-enriched foods, called functional foods, because of the beneficial effects they have previously had on the body. In the present work we want to give a general description of dietary fibre and its role in the body.

  the target for the European Union to make Europe the most competitive and dynamic knowledge-based economy in the world. In this process, the education and training are of great importance for the member states. The restructuring of higher education, the modernization of the universities cannot be achieved without new financial resources. They should be ensured by increasing contribution of the private sector. However it is not enough to invest sufficient funds in the educational and training system, they must be expended efficiently. The free higher education itself does
  not necessarily guarantee the equal access and maximal participation. The quality of higher education and equal opportunity can be improved, if the rising funds are expended on infrastructure development and creating an efficiently working student support system.
  Quality, equal opportunity, efficiency – they are the most important views for the decision-makers in the higher education reform. In my paper, I would like to interpret definitions relating to higher education and in this way I attempt to evaluate the financing systems of the Hungarian higher education formed since the change of the regime, with special regards to the normative financial system combined with the payment of tuition fees. For classification, it is necessary to present the different basic financial models. Furthermore, on the basis of the above criteria, I try to make recommendations on how to improve the present financial model in order to achieve the Lisbon objectives.
  The topic is important in our days, because tuition fees will be introduced in Hungary from 2008. The problem is very complex, although the analysts in most cases tend to approach the topic with prejudice, depending on their financial and political interests. My analysis may contribute to discernment in the tangle of the pros and cons.

  The ecological restoration of surface water flows requires the use of complex GIS and hydrological models. The HEC -RAS and MIKE11 programs calculate the hydraulic characteristics of runoff using the geometry and bed resistance the of flows. The presentation of some possible applications made through an example of the Berettyó, which is an extremely regulated river. The river belongs to the meandering category by Parker's classification system, which uses the relationship of the slope-Froude number and the depth- width ratio. Three coefficient of the four determining factor (entrenchment ratio, slope of water level, width-depth ratio) also indicates a mediocre to high sinuosity, while the river regulations established nearly straight bed-line. The standard water flow rates and characteristics have been determined based on the modeled Froude and Reynolds numbers. The flow conditions shifted to the laminar type by the changed line drawing which is ecologically lower status. Based on the results the morphological and ecohydrological river rehabilitation is appropriate.
