Traditionally, spring is the time of new hopes, new plans, the time of renewal, the time that looks skyward into the future. In spring we plant seeds, and this is no accident. After all, to avoid standstills, we all need to move forward, to develop and improve operations, we need to "learn, learn and study again." Given this, in spring takes place a large number of trainings, seminars and scientific-practical conferences, aimed to supply industry and businesses with new knowledge and skills for future use. For reserve for the future what is it but a guarantee for future success?
