Aircraft Performance Checking Process to Achieve an Acceptable Level of Safety Through the Compliance Monitoring Function

This paper presents a methodology for developing a model for managing the checking process of aircraft performance by forming an audit checklist and examines the possibility of applying the method of multiple criteria decision-making as decision support. In developing this model, Expert Choice software was used and IOSA (IATA (International Air Transport Association) Operational Safety Audit) standards were ranked on the basis of their relevance for aircraft performance and the airline’s relevant data for the particular year by the method of the multiple criteria decision-making Analytical Hierarchy Process (AHP). AHP served as the basis for selecting “critical” standards for a certain audit as an aid to the compliance manager in defining the audit areas and standards to be checked, while using optimum resources. Apart from ranking the standards, the recommended model can be used, by applying a sensitivity analysis, for predicting the need for additional audits

Translation and validation of the Serbian version of the Skindex-29 instrument for measuring impact of skin disease on quality of life

The Skindex-29 instrument, which is intended for measuring the influence of skin diseases on quality of life, was developed and validated in several languages. However, a Serbian translation of the instrument is not available. The aim of this study was to translate the Skindex-29 from English to Serbian, to make necessary cultural adaptations, and to test its psychometric properties in a sample of outpatients with various skin diseases. The Skindex-29 was translated and adapted according to internationally accepted guidelines and then tested on a sample of Serbian outpatients with various skin diseases. Internal consistency was checked through calculation of Cronbach’s alpha and Interclass Correlation Coefficient for the instrument’s domains. The criterion validity of the translation was tested by correlating scores of domains with scores on the Serbian version of Dermatological Life Quality Index (DLQI).Validity of the construct was tested through comparison of the domains scores in groups of patients with different skin diseases. Fifty-three patients (18.6%) suffered from acne vulgaris, 48 (16.8%) from verrucae vulgares, 40 (14.0%) from psoriasis, 34 (11.9%) from an undetermined type of mild dermatitis, 20 (7.0%) from venous ulcers, 19 (6.7%) from eczema, and 71 (24.9%) from other skin diseases. The Serbian translation of Skindex-29 showed good internal consistency: Cronbach’s alpha for Emotional, Symptoms, and Functioning domains was 0.885, 0.752, and 0.901, respectively. Validity of the instrument in all aspects (criterion, content, and construct validity) was satisfactory, yet the Symptoms domain could not discriminate well between more and less severe skin diseases. The Serbian translation of Skindex-29 appears to be a reliable and valid specific instrument for measuring the adverse influence of skin diseases on quality of life. </p

THE ROLE OF THE NATIONAL BANK IN CREATION OF PUBLIC DEBT OF INDEPENDENT KINGDOM OF SERBIA

The time characterized by a public debt phenomenon in modern Serbia has been attached to the end of the XIX and the beginning of the XX Century, when the battle for independence had caused growth of Serbian foreign debt. It is considered that the state’s contraction of debts at the National Bank4 has been old as well as the National Bank institution by its self. In other words, more before the Serbian National Bank’s counters were opened, there was made the state debt by approving the loan of 304,216 dinars in gold, on backing of the state treasury bills. Therefore was made the initial business transaction of the bank, which was done before its regular business activities

Frequency of dysmorphological signs by possum at the home for developmentally handicapped children and adults in Veternik-Novi Sad

The authors have examined frequency of dysmorphological signs by POSSUM at the Home for developmentally handicapped children and adults in Vetemik Novi Sad. The aim was to establish possible different hereditary and congenital skin diseases and genetic syndromes in this population. The study was based on the following methods: method of family history including genealogy; dermatoglyphic methods; screening tests methodology in medical genetics; method of cytogenetic analysis; histo-pathological analysis method of dermatovenerologic, genetic and dysmorphologic examinations of skin diseases by analysis of dysmorphological signs on the skin using a special computer programme. The study s, Novi Sad included 504 wards with 269 males and 235 females, and sex ratio of 1:1.14 in favour to males. Non-parametric statistics and Log-linear analysis revealed a statistically significant difference between the incidence of dysmorphological signs in the studied group and the Vojvodina population. The obtained incidence of dysmorphological signs in the examined group is presented in tables. Our results regarding the incidence of dysmorphological signs in the examined group showed significantly increased values in comparison to the population of Vojvodina

Synthesis of some 3-(thiazol-4-yl)-4-hydroxycoumarins

In this work, an easy and efficient procedure for the synthesis of eight 3-(thiazol-4-yl)-4-hydroxychromen-2-one derivatives is presented. 3-Acetyl-4-hydroxychromen-2-one (1) was brominated with phenyltrimethylammonium tribromide to afford 3-(2-bromoacetyl)-4-hydroxychromen-2-one (2). Compound 2 reacts with thiourea, thioacetamide and ammonium dithiocarbamate to afford 3-(2-aminothiazol-4-yl)-4-hydroxychromen-2-one (3), 4-hydroxy-3-(2-methylthiazol-4-yl)chromen-2-one (4a) and 4-hydroxy-3-(2-mercaptothiazol-4-yl)chromen-2-one (5), respectively. In a similar manner, compound 2 was treated with four mono-N-substituted thioureas and thiobenzamide to give the corresponding 3-(thiazol-4-yl)-4-hydroxychromen-2-one derivatives

Tuta absoluta (Meyrick, 1917) (Lepidoptera, Gelechiidae): nova štetočina paradajza u Srbiji

Tomato leaf miner Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), a devastating pest of tomato originating from South America has been recorded in Serbia on three localities: in tomato main greenhouse and open field production area located in the vicinity of town Leskovac (South Serbia), in surroundings of the village Donji Vrtogoš (near town Vranje, South Serbia) and in a greenhouses complex in Kraljevci (60 km west of Belgrade). The presence of T. absoluta was confirmed by morphological and molecular study of the collected specimens.Prisustvo lisnog minera paradajza Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), opasne štetočine poreklom iz Južne Amerike, utvrđeno je na tri lokaliteta u Srbiji: u plastenicima i poljima u okolini Leskovca (južna Srbija), u okolini sela Donji Vrtogoš (u blizini Vranja) i u kompleksu plastenika u selu Kraljevci (60 km zapadno od Beograda). Identifikacija T. absoluta je izvršena morfološkim i molekularnim analizama sakupljenih uzoraka
