Abstract

The aim of this exploratory investigation was to learn and try to interpret the dreams of 80 Polish and Brazilian children aged 8-12 years old attending primary schools by means of their drawings. Drawing is a resource that allows children to openly express their emotions, fears and dreams. From the precision of their lines and the colors they choose to the painted objects or people and the position they occupy, we learn a lot about how children perceive their surroundings, at school, objects, or the people that are of great importance to them. The drawings of Polish-Brazilian children, despite their disturbance, present dreams rich in details and colors. However, this interpretation is still in its infancy and further research is needed. The drawings collected were analyzed adopting a projective research method. Results obtained indicate the need of further research from other countries.

Abstract

In general, everyone believes that food safety refers to the safety precautions and measures that must be taken in the food industry, but it also refers to cultivating a safety culture in the organization in all departments, in co-operation with the industry's safety department, in order to avoid accidents. This study deals with the how employees in various areas in the food industry undergo safety training. This paper intends to propose a technique for conducting hazard and control measures evaluations in the food sector in order to appropriately construct a safety management system. Manufacturing businesses have increased substantially because of rapid economic expansion, yet safety standards in the manufacturing sector are appalling, posing a serious threat to employees' lives. As a result, factory safety requires a significant degree of improvement. Many organizations have policies in place to limit accident rates, yet statistics show that the industry has a high rate of accidents and injuries. A variety of indicators is used in the safety management system to reduce accident rates. Safety culture in the workplace, behavior safety, and safety performance are all markers of a safe workplace.

Abstract

The objective of this study was to carry out a review of the biological activity produced by some steroid derivatives on cancer using some data systems such as academic google, pubmed, pubchem. The results showed that different functional groups involved in the chemical structure of steroid analogs can produce changes in the growth of cancer cells. In addition, steroid nucleus possibly is essential to generate this effect. In this study are shown some steroid derivatives with biological activity against cancer. Different functional groups involved in the chemical structure of steroid analogs produce changes in the growth of cancer cells, and steroid nucleus possibly is essential to generate this effect.
