Dinamičan razvoj tehnologije materijala doveo je do primjene različitih novih materijala za poboljšanje svojstava nosivosti i trajnosti betonskih nosača. Jedan od pristupa jeste primjena sistema zaštite obložnog dijela betonskog nosača (zaštitni sloj betona). U ovu svrhu, razvijeni su polimerni materijali armirani karbonskim, staklenim ili aramidnim vlaknima (FRP – Fiber Reinfored Polymer). Novi pravac razvoja ovih sistema jeste primjena tekstilom armiranih sitnozrnih betona, gdje se koriste tekstili s vlaknima u više pravaca. Fabrički proizvedena ravninska tekstilna struktura sačinjena je od vlakana upletenih na razne načine, kao što su tkanje, pletenje, filcovanje ili štrikanje. Za potrebe istraživanja i razvoja ovog sistema ojačanja betonskih greda, formirana su dva istraživačka centra u kojima se sprovode projekti pod nazivom „Textile Reinforced Concrete (TRC) -Technical Basis for the Development of a New Technology” (SFB 532) RWTH Aachen University i „Textile Reinforcements for Structural Strengthening and Repair” (SFB 528) Technische Universitat Dresden. U ovim istraživačkim centrima sprovode se istraživanja mehanizama trajnosti, prionljivosti i kapaciteta nosivosti. Pored dva navedena velika projekta, postoji i niz projekata koji se odnose na tekstilom armirani beton, a sprovedeni su u Izraelu, Sjedinjenim Državama, Grčkoj, Belgiji, Ujedinjenom Kraljevstvu i Kanadi [3]. Utvrđeno je da količina i raspored tesktilne strukture imaju značajan uticaj na ponašanje tekstilom armiranog betona. Istraživanja su posvećena:

This study was done with the aim to comparatively analyze the taxonomic and phytogeographical spectrum of lawns along the Belgrade roads. The analysis was done using the results of a floristic research done in 2001, combined with results of the field research conducted in 2019. A comparative analysis of the obtained results has shown that a lower heterogeneity of the floral elements and plant taxa was recorded in the studied lawns in 2019, when compared to the previous research period. Such a reduction in heterogeneity is the result of more intensive measures of lawn care, and of a stronger anthropogenic influence, which has led to a homogenization of the lawn flora.

Genetic counselling is a complex process that helps people to understand and adopt medical, psychological and genetic aspects of the disease and enable them to make an appropriate decision. In this framework, we revisited all the existing models for decision-making and suggested their use in the process of genetic counselling, which may lead to more equitable and more favourable outcomes. Also, Donabedian's (Structure-Process-Outcome) model for the development of key performance indicators was applied to assess the quality in the process of genetic counselling. Quality indicators at SPO model in the process of genetic counselling were proposed. The social, economic and humanistic outcomes have also been identified. All defined quality indicators together represent a framework for monitoring, evaluation and continuous improvement of the process of genetic counselling. Although the new medical services of genetic counselling tend to be developed as a powerful multidisciplinary field, the implementation of quality management model will certainly help the development of collaborative practice.

Objective. Continued Professional Development (CPD) is one of the most significant precursors to increased competency. Appropriate instruments and support are required for its implementation. This paper demonstrates the attitudes held by pharmacists on the impact of the competency framework on CPD, its acceptance among Serbian pharmacists and potential future application. Furthermore, the motivational impact of the competency framework on CPD as well as the relationship between certain demographic indicators and motivators of CPD are provided. Method. Research on the cross-sectional method throughout 2015-16 included pharmacists working in publicly-owned pharmacies. The survey was anonymous and voluntary. The questionnaires generated for this research contain demographic data on those surveyed and open-ended questions with multiple choice answers and applied a Likert-type scale. Statistical analysis was conducted by applying Microsoft Office 2003 and the Statistical Package for Social Sciences (SPSS) version 22. Results. Among the respondents, the female gender dominated, respondents who had not completed a speciality within their respective field, with an average age of 42 years, and an average of approx. 15 years of service. 26.12% of the respondents had prior experience with the competency framework. Most respondents were of the opinion that these instruments motivated them to actively manage their own PD, to set concrete PD objectives and to review their own competency. Over half intend to apply competency frameworks in future. The statistical Chi-square test indicates it is not possible to determine with certainty that there are differences in terms of motivation in managing PD and in PD goal setting between the groups of variables. Conclusion. The research indicates a positive attitude/opinion of pharmacists towards the competency framework and in recognising these instruments as supportive to CPD.

SUMMARY Background : Critical limb ischemia (CLI) represents the end stage of peripheral arterial disease (PAD). It is defined as a chronic ischemic rest pain, ulcers or gangrene, attributable to proven arterial occlusive disease. Intra-arterial digital subtraction angiography (IA DSA) still represents the gold standard for the evaluation of steno-occlusive lesions, but it has greatly been replaced with non-invasive multi-detector computed tomography angiography (MDCTA). The purpose of this prospective study was to compare diagnostic performance of MDCTA versus DSA in treatment planning in patients with CLI according to TransAtlantic Inter-Society Consensus Document on Management of Peripheral Arterial disease (TASC II). Subjects and methods : The study was designed as prospective; it was conducted from March 2014 to August 2016, and included 60 patients with symptoms of CLI, Fontaine stage III and IV. MDCTA of the peripheral arteries was performed first, followed by DSA. The lesions of aorto-iliac, femoro-popliteal and infra-popliteal regions were classified according to the TASC II guidelines, and inter-modality agreement between MDCTA and DSA was determined by using Kendall’s tau-b statistics. Results : Inter-modality agreement was statistically significant in all three vascular beds, with excellent agreement >0.81 in aortoiliac and femoropopliteal regions, and a very good agreement >0.61 in infrapopliteal region. Treatment recommendations based on MDCTA findings and DSA findings were identical in 54 (90%) patients. In one patient (1.7%), CTA was not interpretable. In five patients (8.3%), CTA findings disagreed with DSA findings in regard to the preferable treatment option. Conclusion : 64-row MDCT angiography is highly competitive to DSA in evaluation of steno-occlusive disease and treatment planning in patients with critical limb ischemia.
