Summary Public health is a broad field that touches several different medical disciplines such as epidemiology, public health informatics, health statistics, environmental protection (ecology), sociology, health promotion, disease prevention and organization of health care for nosological groups of the population. In Europe and the world today is developed a fairly extensive network of scientific and professional institutions engaged in research projects, studies, organization of scientific conferences and publishing scientific and professional articles from the field of public health. Their goal is to promote scientific advances in the field of public health through the exchange of experiences of public-health professionals, training, demonstration of appropriate research models, simulation and application in medical practice.

Summary Introduction: In recent decades, the development and improvement of technology is rapidly advancing. The development of science, new materials, information technology, new procedures and other modern achievements were his first confirmation sought to improve living conditions, particularly in achieving better health conditions. In an effort to improve living conditions, solve the problem of severe diseases and to facilitate treatment, new technologies, almost always find its first application in medicine. In such conditions of general pressure of new modern technologies, health professionals often succumb to uncritically use these technologies. Methodology: Analyzing data collected from 30,000 research papers that have done 30 doctors of family medicine and 30 doctors of general medicine, and from interviews conducted with all 60 doctors who participated in the research. Results: a) Teams of family medicine have a significantly higher professional education, and it should be noted that there was no significant difference in length of service of employees; b) Teams of family medicine have significantly less committed population on which the care; c) Teams of family medicine in an average have fewer visits per day than the teams in general medicine; d) Information diagnostic technologies are more accessible to family medicine teams. Conclusion: It is necessary to introduce a technology assessment as a standard scientific methods in decision making and the creation of the health system. In fact, it is necessary to establish and enable institutions to assess health technologies and join the developed world in creating better health care.

As a proposal for an undergraduate second or third year inorganic laboratory course, the present paper describes the preparation of three representative boron complexes: potassium tetrafluoroborate, pyridoxin boron complex and potassium bis(oxalato)borate. The complexes are characterised by infrared and multinuclear magnetic resonance spectroscopy (1H, 11B and 19F) where isotopic effects are demonstrated.
