Nanotechnology is a new technological branch that involves the use of molecular size substances, usually below 100 nanometres, that can be integrated with most technologies and applications, which has strong industrial potential for competitiveness and resource efficiency, but also a great impact on quality of life and sustainable development. It is increasingly used in the food industry to improve the properties of food (functional food) and materials that come into contact with food, in the control of food safety, and especially in food packaging processes. The term "nanofood" has been introduced for food grown, produced, processed or packaged using nanotechnology or with the addition of nanoparticles. The positive effects of nanotechnology in the food sector are generally well described, however, the risks and negative impacts that nanoparticles may have on biological systems have not yet been fully elucidated. The paper presents the latest achievements in the application of nanotechnology in the food industry, safety and potential risks and the impact of nanofood on human health.

Despite the great development of techniques and technology many workplaces are still very risky. To enable a safer work activity, personal protective equipment is developed for individual types of activities to protect workers from potential hazards and injuries. The paper presents personal protective equipment for forestry workers, which includes protective clothing, gloves, shoes and a protective helmet. Proper use of personal protective equipment significantly reduces the risk of injuries and occupational accidents.

Tracking for wounded game animals with a tracking dog is one of the most demanding disciplines of hunting cynology. Tracking demands sharp skills, concentration and specialized equipment both for the dog handler and tracking dog. Equipment must be practical and functional with protective features at the same time. Tracking can be done through whole year around, from warm and dry to cold and wet weather conditions. Terrains can be very different from sharp rocks or high forests to thick and thorny bushes or even mud plains. Besides that, there is a high risk of getting wounded by a wild animal while tracking. Therefore, equipment must also be impenetrable and durable. In this paper you can read more about specific equipment for dog handlers and tracking dogs.

This paper presents the most important documents of international, European and Croatian legal regulations regarding the management of stress at work. In the practical part are presented the findings wich were obtained on the basis of data collected through web questionnaires. To compare with the obtained results was used a survey conducted in 2020. with the same topic. The research shows that the respondents are insufficiently acquainted with the regulations related to stress management at work. The data show that stress is relatively poorly managed in our companies. In most cases, even the minimum legally prescribed activities are not carried out such as psychosocial risk assessment, prevention of stress at work, consulting with employees and informing them about prevention.
