Course abstract

The study course introduces the connection of scientific research with the principles of constructor design, approximates the incorporation of knowledge gained by forest work technologists into newly designed equipment, helps to conduct research on the technogenic impact on the forest environment and vice versa. Provides preconditions for the development of forest technical requirements when planning the design of new forest equipment.

Learning outcomes and their assessment

The criterion is the percentage compliance with the 10-point grading scale. The assessment in any of the study results must not be less than 50% of 8 points, or it must be at least 4 points.
