Amidst the globalization of markets, there has been a continuous intensification of competitiveness between enterprises. The modern business environment has caused a shift in how business is conducted. Opportunities and challenges arise, which put a tremendous pressure on enterprises regardless of size and industry. Entrepreneurship in enterprises plays an important role in obtaining a competitive edge in the market. Thus, entrepreneurial intentions in enterprises can often shape the future and survival of the enterprise. In this paper, the prediction of entrepreneurial intentions in enterprises through Internet marketing predictors is addressed. For this, several statistical methods in data mining were used. First, simpler approaches such as linear regression, logistic regression were used. Afterward, classifier decision trees QUEST (quick, unbiased, efficient, statistical tree), and CHAID (chi-squared automatic interaction detection) were used. The sample for analysis was 137 enterprises from Serbia. Furthermore, a supervised machine learning algorithm, support vector machine (SVM) was used. Finally, a feed-forward neural network (FNN) was applied. The results varied across the applied approach, thus providing significant insights into the dynamics of data mining for prediction outcomes in an enterprise setting.

Medical waste management is of great importance for people and the environment. Irresponsible management and classification of medical waste can lead to environmental hazards and cause health risks to both employees and patients.

The outbreak of COVID-19 coronavirus and appropriate precautions measures to limit its spread have clear impacts on human mobility globally. This has caused a reduction in the domestic and international volume of air passenger traffic and the readiness of passengers to decide to travel to foreign countries. Due to the global coronavirus crisis, most countries have introduced restrictive measures to limit the pandemic and limit the number of victims. Among the restrictive measures is the suspension of air traffic as an effective measure in reducing mobility at the global level in the short term, which results in a high socio-economic imbalance in both the long and short term. This paper deals with the examination of knowledge and application of precautionary measures at airports, safety and readiness of passengers to travel and their travel experiences.
