Albanian farmers have and continue to cultivate farmer’s bean cultivars because they are adapted to the country’s conditions and to the cultivation practice of the farmer who uses low levels of chemical fertilizers in beans. But, in the current conditions, the landraces are at risk of genetic erosion due to socio-economic changes. Therefore, our concern and obligation is to preserve the common bean farmer’s cultivars, not only to be cultivated but also to be used in genetic improvement programs. This was the aim of this study through which to know the genetic variation of the farmer’s cultivars in order to increase the effectiveness of the genetic improvement programs of this plant of great value to the people. In the study, 40 accessions (farmer’s cultivars) collected in the northeastern and eastern areas of Albania and stored in the Albanian Genetic Bank were taken.

Extended Reality (XR) stands as a hypernym for Augmented Reality (AR), Mixed Reality (MR) and Virtual Reality (VR) technologies and represents an increasingly important Industry 4.0 technology rank. XR technologies are enriching or replacing the environment with digital information. This introduces new possibilities for learning, collaboration, product presentation or other fields of application in companies. Various meta- and individual studies prove a positive influence of XR elements on learning success. However, the appraisal of results must be made with caution since no standard is currently available to measure learning success. This paper contributes to this situation by providing a framework to perform a generic measurement of learning success when using XR. The developed framework follows the 4-level evaluation model according to Kirckpatrick focussing on response, learn, apply, and benefit to the organization and is further developed meeting the specific requirements of XR training. The developed framework adresses two dimensions: the evaluation of the short term as well as the long-term training success. Furthermore, the paper gives insights in the practical validation of the framework done by an industrial company using a VR Training within the onboarding process. The framework is intended to help organizations to systematically assess the learning success of XR-supported training compared to traditional paper-based training.

As technology advances every day of our lives and generates vast amounts of data while different systems, sensors etc. are working, it is important to meet their needs and demands. Digitalization is one of the biggest driving forces for developing of databases – relational and non-relational – in every sphere that they are used, and especially the utilization of NoSQL dBs in areas that were once unthinkable. Financial services offered by different institutions usually relied on relational databases only, but with continuously changing technologies new ways for managing data emerged. This paper presents an automated tool for evaluation and selection of NoSQL databases intended for financial services based on predefined criteria.

The classifications of innovation strategy of industrial enterprises are investigated: their advantages and disadvantages are determined. Classifications of innovation strategy of industrial enterprises are improved. Classification features, types of strategies of innovation activity of industrial enterprises are characterized. The expediency of using a certain innovation strategy of industrial enterprises is substantiated.

Prevention of industrial accidents in Europe and creation readiness of the authorities and the community for countering them are aimed not only at major catastrophes, but also at the small ones, which threaten the society, jobs and environment. Regardless of the internationally accepted framework for prevention and counteraction the industrial accidents involving hazardous substances (refers to the Seveso type site/area related accidents), there are fields that have not yet been developed, such as an assessment of the vulnerability of various sectors of economy, their interdependencies and the impact on social life. Considering these challenges, the main objective of the current article is to bring to the attention of stakeholders an integrated package of advanced developments, both in terms of Seveso type site/area related accidents, caused by reason of technological failures (technological mistakes) or are due to targeted man-made activities (terrorism).
