Poland’s energy dependence - economic context
Open Research DataPoland does not have vast resources of non-renewable energy and no nuclear power plant, therefore the issue of the energy dependence of the state, which affects the level of energy security of the country, is an extremely important factor. It depends on both the volume of imports of energy raw materials and the policy of diversification of sources of...

Assessment of the activities of private universities in the context of quality management in 2010
Open Research DataIn all universities, the assessment of the quality is made by the supervisor, the opinion of students and the admission of classes have the greatest impact on the assessment of the quality of education. Subsequent tracking of the student's fate has a slightly smaller impact on the grade. Research also shows that only 4 out of 7 respondents monitor the...
