41. Evaluation of the acidity in samples of virgin olive oil for the 1995-2005 period and correlation between the collected data and the performed sensory analysisVasilij Valenčič, Erika Bešter, Milena Bučar-Miklavčič, Bojan Butinar, 2007, izvirni znanstveni članek Opis: The acidity and organoleptic characteristics of virgin olive oil produced in Slovenian Istra were studied. The acidity of 4,871 samples of virgin olive oils was determined for the 1995-2005 period. 135 samples produced in crop year 2002/2003 with acidity below 0.2% (w/w) and 291 samples of crop year 2005/2006 were sensory evaluated. According to sensory evaluation in crop year 2002/2003, 128 out of 135 samples were classified as extra virgin olive oils, while 7 samples did not reach the specified requirements. In crop year 2005/2006, it was established that 71.5% of the analysed samples complied with extra virgin category, 24.4% with virgin and 4.1% with lampante. Time of harvest, storage conditions before processing, and time from picking to processing all influenced the oil quality, whereas olive cultivars did not. Chemical and sensory analyses were performed according to the Commission Regulation (EEC) No 2568/91 and added annexes.

42. Evaluation of measurement uncertainty for the methods of analysis used to assess the characteristics of olive oil and olive-pomace oil from commission regulations EEC 2568/91 and EC 1989/2003 : a case sample evaluating the measurement uncertainty for peroxide valueBojan Butinar, Milena Bučar-Miklavčič, Erika Bešter, Vasilij Valenčič, 2007, izvirni znanstveni članek Opis: Metrology has been present in our scientific knowledge for a long time, but mostly in physical measurements. Chemical measurement can be defined as a comparison of a quantity of measurand and relating it to a unit (e.g. mol/kg).When expressing a result of a measurement, the problem of traceability, validation and the measurement uncertainty (MU) evaluation must be challenged. It is well known that MU is a parameter associated with the result of a measurement that characterizes the dispersion of the values that could reasonably be attributed to the measurand. The EEC document 2568/91 with its annexes gives the methods of analysis to assess the characteristics of olive oils and olive-pomace oils with given limits. The EC document 1989/2003 gives the scheme, the algorithm, the pathway, the decision tree to differentiate between various types of olive oils using the particular determinations based on limits. The major lack of these EC methods is the non-existence of validation parameters, which are crucial in determining the MU (and in accreditation of a laboratory). There are several ways of evaluating (better term than calculating) the MU: with model equation, with use of a certified reference material (CRM) and with participation in a proficiency testing (PT) scheme. MU for a method of analysis is inherent to a laboratory and can serve as a tool for 'measuring' the quality of a laboratory. Unfortunately, there are practically no CRM's in the olive oil testing field. The only way to achieve a usable MU is through participation in PT schemes.

43. Garden as an eye : the garden of the venetian palace Soranzo-CappelloErika Zlatkov, 2008, izvirni znanstveni članek Opis: This paper concerns the garden of the Venetian palace Soranzo-Cappello and is situated in a wider iconological and symbolic-theoretical framework. The garden is a continuous meeting of opposites, which succeed in coming to life as a harmonious whole; it is a symbolic space on account of its specific emplacement between nature and cultural landscape, and it is a space of symbols, since it has its own inner speech. The garden's appearance is subjected to climatic, temporal and terrestrial influences, and also to the will of man, who shapes it. The purpose of this study is to lead ourselves to thinking of a garden as a work of art, for man's power of expression is not only real, material; it is also spiritual, immaterial. The Venetian garden represents the interweaving of both. It is a work of art in open space, to which is also given a useful value. It is an emblematic figure, a mental and formal space which differs from the surroundings - both reflective and thoughtful

50. The presence of anxiety and depression in the adult population of family practice patients with chronic diseasesZalika Klemenc-Ketiš, Janko Kersnik, Erika Tratnik, 2009, izvirni znanstveni članek Opis: Background: The prevalence of multimorbidity in family practice is rising and psychiatric comorbidity presents a risk factor for premature mortality. Objective: The aim of this study was to determine the prevalence of anxiety and depression in the adult population of family practice patients with chronic somatic diseases, aged between 18 and 64 years old. Methods: We performed a cross sectional study in 500 consecutive patients from twelve family practices. Zung's self-assessment inventories for anxiety and depression were used to determine the presence of psychiatric comorbidity. The main outcome measures were depression and anxiety scores in patients with various comorbidities. Results: The response rate was 90.4 %. 8.4 % of family practice visitors suffered from anxiety symptoms and 15.2 % from depressive symptoms. At least one chronic disease was present in 40.7 % of the patients. Significantly higher rates of depression and anxiety were found among patientswith chronic somatic disease (p=0.001, P<0.001, respectively; ?2 test)or chronic pain (p<0.001, p<0.001, respectively; ?2 test). Significantly more patients with rheumatic diseases had depression in comparison to those without them (p=0.018; ?2 test). Significantly more patients with migraine or rheumatic diseases had anxiety in comparison to those without them (p=0.010, p=0.030, respectively; ?2 test). Chronic pain was present in significantly more patients with a particular chronic disease in comparison to the patients without it (p<0.050; ?2 test). Conclusions: Family doctors should actively search and treat psychiatric comorbidity also in the population of patients with chronic somatic diseases, aged between 18 and 64 years old.
