Dry matter, organic acids, ascorbic acid, minerals (nitrogen, phosphorus, potassium, calcium, magnesium, sodium) and polyphenolic profile of a number of non-traditional fruit species and their genotypes, namely blue honeysuckle (Lonicera spp.), Saskatoon berry (Amelanchier alnifolia), black mulberry (Morus nigra), Tomentosa cherry (Prunus tomentosa Thunb.) and jostaberry (Ribes nigrum x Grossularia uva-crispa) were investigated. The results showed that Lonicera genotypes displayed high levels of ascorbic acid and they were rich in minerals, with the cultivar ‘Amfora’ achieving the leading position in nitrogen, phosphorus and potassium content among all lesser known fruit species. Amelanchier cultivars represented a valuable source of ascorbic acid and calcium, ‘Tišňovský’ and ‘Smoky’ together with Morus nigra ‘Jugoslavska’ accumulated the highest level of examined polyphenolic compounds. Regular consumption of studied less common fruit species can bring health benefits so they can represent a high potential value for fruit growers and in addition they can be utilised as functional foods.

We are trying to point out new methods of education by means of mobile technologies and smart devices. The results of questionnaire exploration at the participating universities were analyzed from the point of view of student used mobile technologies, where we compared the mode of using mobile technologies among universities in Hungary and Slovakia. We are thinking about study field of Information science, Natural Science, Arts and Social sciences. We think about types of mobile devices according to type of operation system supplied by the vendor. Based on cluster analysis and principal component analysis (PCA), we evaluate correlations among particular components of using mobile technologies by students in order to improve knowledge in education. We consider the mobile technologies as information channels, which brings knowledge to students. The aim of our research is evaluation of particular data and finding rules between components of using mobile technology by students and mapping the performance. And more, our aim is to give recommendations for appropriate combination of information channels mostly used by students of participated universities, running fields of study and mobile technologies used by students. In our paper we talk about Interactive Voting through Mobile Device as recent and interesting way of using mobile technologies.

During the last decades we have been witnesses of a very rapid technical revolution. Today we are surrounded by smart devices (smart phones, smart TVs, smart houses, smart cars) that have radically transformed our daily life as well. Learning methods and information gathering techniques of the youth has become quite different from that of their parents'. Lecturers have to change their educational tools due to this new need to be able to achieve students' attention and produce a better result. We worked on a bilateral Hungarian-Slovakian tender (TéT_12_SK) which dealt with teaching mobile development and using them in education. In this paper we would like to present our work.
