Abstract:To examine attitudes about information system security among Croatian physicians a cross-sectional study was performed on a representative sample of 800 Croatian physicians. An anonymous questionnaire comprising 21 questions was distributed and statistical analysis was performed using a chi-square test. A 76.2% response rate was obtained. The majority of respondents (85.8%) believe that information system security is a new area in their work. In general, physicians are not informed about European directives, conventions, recommendations, etc. Only a small number of physicians use personal computers at work (29%). Those physicians who have a personal computer use it mainly for administrative reasons. Most health-care institutions (89%) do not have a security manual and the area of information system security is left to individual interest and initiative. Only 25% of physicians who have a personal computer use any type of password. A high percentage of physicians (22%) has never thought about the problem of personal data being used by organizations (e.g. police, banks) without legal background; a small, but still significant percentage of physicians (5.6%) has even agreed with such use. Results indicate that for the vast majority of physicians, information system security is a new area in their daily work, one which is left to individual interest and initiative. They are not familiar with the ethical, technical and legal backgrounds which have been defined for that area within the Council of Europe and the European Union. New aspects: This is the first study performed in Central and Eastern Europe dealing with information system security, performed on a representative nationwide sample of all the physicians.

For the first time, a detailed study of the chemical composition of ethanol extract of dried marsh (swamp), a product obtained after preliminary exhaustive last ex-traction with n-hexane, toluene, chloroform and acetone was performed. Chromatography-mass spectrometry made it possible to identify 119 individual compounds in this extract with the determination of their quantitative content, mass spectra and structural formulas, and the calculation of the structural-group composition was performed. A characteristic feature of the extract is the presence of significant amounts of nitrogen and sulfur-containing compounds (20.04), esters (21.47), sterols (18.54), carboxylic acids (8.15) and hydrocarbons (7.15) (wt. % of the extract). In addition, the extract contains phenols, ketones, aldehydes, alcohols and glycosides: 5.01; 4.34; 4.88; 3.16 and 3.12 (wt. % of the extract), respectively. Dominance in the extract of nitrogen-sulfur-containing and compounds; environment of sterols-betulin and its derivatives, esters, as well as the presence of different structure of phenols, glycosides, aldehydes and alcohols makes it possible to assume a wide range of pharmacological activity of drugs based on ethanol extract of dried marsh (marsh).
