    Machines. Technologies. Materials., Vol. 16 (2022), Issue 11, pg(s) 369-372

    With the developing food industry applications, the use of gastronorm containers is also increasing rapidly. It is widely used to transport, cook, preserve and serve gastronorm containers and food products. In line with international standards (EN 631-1, EN 631-2, etc.), the production process becomes more complex as the depth of gastronorm containers increases (from 20 mm to 200 mm / 6 different depths) and the process steps increase. Due to the errors arising from the process stages, there is an increase in the number of rejects, and thus energy efficiency is adversely affected. An automatic pressure balancing system design has been developed in accordance with the workflow in gastronorm container manufacturing with deep drawing technology. Providing the elimination of excess pressure steps and heat treatment needed in deep gastronorm containers (sizes and depths respectively: 1/2 200 mm, 1/3 150 mm, 1/3 200 mm, etc.), as well as the unique design of the integrated deburring machine, a significant innovation with industry 4.0 application has been imparted. Thus, in addition to the increase in product quality, it contributed to reducing unit costs by reducing high waste rates below 5%.

    In the context of large-scale and diverse forms of international assistance for the post-war reconstruction of Ukraine, it is necessary to identify and offer foreign partners a format to support tourism in our country, especially inbound one. A possible proposal is to develop an international program to encourage foreign tourists to come to Ukraine on special tours, which will be partially funded by donor countries. Combining domestic tourist flows with foreign flows of this type is possible through tourist events, especially festivals. In this format, the festival will have significant synergetic potential, as it will be a point of unification of tourist flows in time and space. The experience of international kite festivals as a special form of event tourism is researched. It allowed to summarize certain features of festivals as tourist events. Certain aspects and features proved the complexity of such phenomena as a tourist event, festival event, the complexity of their preparation and conduct, active interaction with socio-economic processes in the territory.

    Approaches to support learning in today´s workplace

    Industry 4.0, Vol. 6 (2021), Issue 4, pg(s) 169-173

    Workplace learning supports acquiring knowledge and practical skills also to use up-to-date equipment by formal or informal methods and means and occurs mostly in the workplace. It contributes to learning of employees, employers and the organization as a whole.
    As a response to COVID-19 disease, workplace learning had to be changed. Companies need to consider Industry 4.0 to stay competitive in the market. Among the challenges regarding the transformation towards Industry 4.0 are requirements to re-skill the staff for the new work environment by using digital technologies. The staff has to adapt to the workplace transformation brought by digitalization, automation and robotic. So, learning at the workplace should be changed supporting cost-effective delivery modes, easy to access leaning resources, and flexible learning environments. This paper aims to present first some existing forms, benefits and requirements of workplace learning as well as factors that are impacting the workplace and can support to drive a new approach to workplace learning. Second, some learn ing methods
    like interdisciplinary experiential ones, reflection as well lifelong learning (LLL) supported by digital technologies are proposed which can be applied within workplace learning.
    Results about existing approaches in published papers, including the author ones, as well as of projects in this field have been used.
    Recherche has been done by the Study Group Lifelong Learning of the IAT, coordinated by the author. Finally, the methods described in this paper for workplace learning have been tested within an Erasmus+ project with participation of the author. The results should help managers, education responsible, employees to rethink their whole approach to workplace learning: the culture, tools, methods by adopting a new, modern understanding of what it means to learn at work by using digital technologies. The results should be tested also within other projects because due to changed situation during the Covid-19 and after it not all proposed approaches have been applied in optimal conditions. The factors driving workplace learning and the combination of described learning forms described in the paper have not been applied in this form until now.
