The presentation of the theoretical part of the material during the lecture classes is followed by the corresponding examples which contribute to the better understanding of the subject matter. The students independently study the suggested literature which they later discuss with the lecturers at the consultation classes. Through research and study work the student will, on the bases of scientific journals and other relevant literature that has been studied independently, develop further understanding of the material covered in lectures. Working with the course teacher the student develops the ability to independently work on a scientific paper.
