3. Prediction of the ultraviolet protection of cotton woven fabrics dyed with reactive dystuffsPolona DobnikDubrovski, Miran Brezočnik, 2009, izvirni znanstveni članek Opis: Textile materials provide a simple and convenient protection against UV radiation. To assign the degree of UV radiation protection of textile materials, the Ultraviolet Protection Factor (UPF) is commonly used. This paper reports the effect of woven fabric construction (yarn fineness, type of weave, relative fabric density), the colour of bifunctional reactive dyestuffs, and Cibacron dyed fabrics on the ultraviolet protection of light summer woven fabrics. A predictive model, determined by genetic programming, was derived to describe the influence of fabric construction. Warp and weft densities, weave factor and CIELab colour components were taken into account by developing the prediction model for UPF. The results show very good agreement between the experimental and predicted values.

4. The precracking of wide plate specimensVladimir Gliha, Danilo Rojko, 2003, izvirni znanstveni članek Opis: The behaviour of uniformly thick small and largescale fracturetoughness specimens was analysed during fatiguecrack progression. Because of the increasing crack length, the stiffness of the specimens decreases. If cyclic loading is applied in the loadcontrol mode, the stressintensity factor range, ▫$Delta$▫K, and crack growth per cycle, da/dN, increase, which is not appropriate for controlling the size of the crack. The increase in ▫$Delta$▫K for the wide plate (WP) specimens discussed is three times lower than for single edge notch bend (SENB) and compact tension (CT) specimens. The loading range decreases if cyclic loading is applied in the displacementcontrol mode. The values of ▫$Delta$▫K and da/dN for SENB and CT specimens then decrease, which is helpful for controlling the crack size; however, they increase for the WP specimens in spite of lowering the loading range. This increase is one third lower than for the loadcontrol mode, which means that it is somewhat easier to control the size of crack.

5. Improved frequency characteristics of the randomized PWM boost rectifierFranc Mihalič, Miro Milanovič, Carlos Cuoto, 2003, izvirni znanstveni članek Opis: A randomized pulse width modulation (RPWM) algorithm is applied in the control unit of the boost rectifier to achieve improved frequency characteristics in the wide band. First, the introduction of the RPWM switching is reflected in a smaller increase of the total harmonic distortion (THD) factor in the input current. Nevertheless, decrease of the power factor is negligibly small. Second, the power spectrum density (PSD) of the input current is estimated and measured to evaluate the influence of randomization in the highfrequency range. This approach offers an effective and credible prediction method for reduction of conductive electromagnetic interference (EMI) by using the RPWM switching.

7. Characterization of reducible hexagons and fast decomposition of elementary benzenoid graphsAndrej Taranenko, Aleksander Vesel, 2008, izvirni znanstveni članek Opis: A benzenoid graph is a finite connected plane graph with no cut vertices in which every interior region is bounded by a regular hexagon of a side length one. A benzenoid graph G is elementary if every edge belongs to a 1factor of G. A hexagon h of an elementary benzenoid graph is reducible, if the removal of boundary edges and vertices of h results in an elementary benzenoid graph. We characterize the reducible hexagons of an elementary benzenoid graph. The characterization is the basis for an algorithm which finds the sequence of reducible hexagons that decompose a graph of this class in ▫$O(n^2)$▫ time. Moreover, we present an algorithm which decomposes an elementary benzenoid graph with at most one pericondensed component in linear time.

9. The multiple criteria assessment of social responsibility in organizationsVesna Čančer, Simona Šarotar Žižek, 2013, objavljeni znanstveni prispevek na konferenci Opis: The assessment of social responsibility (SR) in organizations requires a hierarchy of requisitely holistic factors and indicators. This paper introduces the development of measuring instrument for this multidimensional problem. Differently from using factor analysis based on principal component analysis extraction method, it presents the use of exploratory factor analysis(EFA) to develop the multiple criteria model for the assessment of SR.It also discusses several approaches for the weights determination: because considering factor loadings of the indicators obtained via EFA does not tend to differentiate between the levels of importance, the SMARTER method based on ordinal scale was used in criteria weighting. It proposes the solutions for measuring local alternativesʼ values with respect to indicators by using value functions. Application possibilities of the results of the multiple criteria assessment of SR are illustrated and discussed via a reallife case of organizations in Slovenia.

10. The impact of the intellectual charm of physicians on the healthcare organizationsElena Marulc, Gabrijel Devetak, 2013, izvirni znanstveni članek Opis: The recession has greatly affected the business operations of every undertaking, including healthcare organizations. Change is required. This also concerns the relationship towards employees in terms of their influence on the successful business operations of an organization. Among employees, physicians possess a special, now already traditional status; therefore, their influence needs to be taken advantage of. In the empiric part of the study, we have identified twelve key physician competencies, based on the rankings of physicians, which, in their mind, influence successful business operations of their respective healthcare organizations during an economic recession. The comparison of the collected results to the findings on intellectual charm of managers has indicated that the collected key competencies, that are creativity, quality, education and personal development, attitude towards others, team work and cooperation, communication skills, problem management, business integrity, motivation and stimulation, multidisciplinary thinking, attitude towards culture and ethics, and acceptance of differences, form a whole which is named the intellectual charm of physicians.
