The aim of the research is to determine the characteristics of the prosocial behavior of primary and high school students in terms of the structure of leisure time. The sample of respondents consists of 230 students of the final grades of primary and high schools, both genders, aged 14-19. The research was conducted in the area of Tuzla during the school year 2017/2018. years. The survey used the measuring instrument "Scale of self-assessment of juvenility behavior YSR". Mann Whitney U test was used for statistical analysis of data. When analyzing the prosocial behavior of primary and high school students in terms of the structure of leisure time, statistically significant differences at the level of p≤0,05 were established in such a way that students with structured leisure time compared to students whose leisure time is not structured more often : are fairly honest, they do things better than most children, they can be pretty friendly, they are skillful with their hands, they fight for their rights, enjoy being with other people, they like to make others laugh, they like to help others.

Reconstructions of the primordial power spectrum (PPS) of curvature perturbations from cosmic microwave background anisotropies and large-scale structure data suggest that the usually assumed power-law PPS has localised features (up to \sim 10\%∼10% in amplitude), although of only marginal significance in the framework of \LambdaΛCDM cosmology. On the other hand if the cosmology is taken to be Einstein-de Sitter, larger features in the PPS (up to \sim 20\%∼20% in amplitude) are required to accurately fit the observed acoustic peaks. Within the context of single clock inflation, we show that any given reconstruction of the PPS can be mapped on to functional parameters of the underlying effective theory of the adiabatic mode within a 2nd-order formalism, provided the best fit fractional change of the PPS, \Delta{P}_{R}/{P}_{R}ΔPR/PR is such that (\Delta{P}_{R}/{P}_{R})^3(ΔPR/PR)3 falls within the 1\,\sigma1σ confidence interval of the reconstruction for features induced by variations of either the sound speed c_\mathrm{s}cs or the slow-roll parameter \epsilonϵ. Although there is a degeneracy amongst these functional parameters (and the models that project onto them), we can identify simple representative inflationary models that yield such features in the PPS. Thus we provide a dictionary (more accurately, a thesaurus) to go from observational data, via the reconstructed PPS, to models that reproduce them to per cent level precision.

This study analyzes the impact of conventional index (SASX-30) on Islamic index (SASE-BBI) in Bosnia and Herzegovina. In the study are used daily index observations spanning in a period from October 2016 until May 2018. The data is obtained from the Sarajevo Stock Exchange database. Vector Auto-regression analysis (VAR) and Impulse response functions are used in order to estimate the impact. The results show that there is a significant negative impact of conventional index volatility (SASX-30) on Islamic index volatility (SASX-BBI) in Bosnia and Herzegovina.

The paper deals with the three-dimensional (3D) modelling based on data acquired from 2D laser sensor and IMU (Inertial Measurement Unit) attached to the UAV (Unmanned Aerial Vehicle). The used multi-sensor unit produces 2D scans and provides information about Euler angles or quaternions. These angles are used to describe the UAV orientation in 3D space, more precisely the orientation of the laser sensor. In order to generate 3D occupancy map it is necessary to rotate the laser sensor around its axis yielding the 2D scans being mapped on 3D space using quaternions. Inertial sensor and Sweep LiDAR laser measurements are transmitted to the single board computer Odroid XU4 (SBC). The data fusion was performed under ROS (Robot Operating System) installed on the SBC, producing 3D space points. These points are transmitted over the network to the central computer on which the UAV localization and mapping processes are done within the ROS. The effectiveness of the proposed system for 3D modelling of the UAV environment is verified by experiment.

The paper presents a custom-made radiometric thermography system which provides a full radiometric IR inspection. It contains heterogeneous stereo-vision system with RGB and thermal camera, as well as the processor unit with developed embedded software modules. The software units were realized using C++ programming language within ROS development environment. In order to obtain the better representation of points in the space as well as their projections on the cameras planes, the stereo calibration was performed. The correspondence between RGB and thermal images is represented with homography. The object detection is performed using OpenCV feature detectors, while the recognition is carried out by Hu moments computation and K-means clustering. For the showcase, incandescent light bulbs, LED light bulbs and quartz heaters are detected and recognized as such. The developed system is capable of providing a heterogeneous inspection of heating systems, power lines, etc.

Direct numerical simulations (DNS) of knitted textile mechanical behavior are for the first time conducted on high performance computing (HPC) using both the explicit and implicit finite element analysis (FEA) to directly assess effective ways to model the behavior of such complex material systems. Yarn-level models including interyarn interactions are used as a benchmark computational problem to enable direct comparison in terms of computational efficiency between explicit and implicit methods. The need for such comparison stems from both a significant increase in the degrees-of-freedom (DOFs) with increasing size of the computational models considered as well as from memory and numerical stability issues due to the highly complex three-dimensional (3D) mechanical behavior of such 3D architectured materials. Mesh and size dependency, as well as parallelization in an HPC environment are investigated. The results demonstrate a satisfying accuracy combined with higher computational efficiency and much less memory requirements for the explicit method, which could be leveraged in modeling and design of such novel materials.

CONCLUSION: The data suggest that 3 days of voice rest followed by voice therapy may lead to better wound healing of the vocal fold compared to 7 days of voice rest. METHODS: Patients undergoing phonomicrosurgery for leukoplakia, carcinoma in situ, vocal fold polyp, Reinke's edema, and cyst were chosen. Participants were randomly assigned to voice rest for 3 or 7 postoperative days. Voice therapy was administered to both groups after voice rest. Grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, stroboscopic examination and Voice Handicap Index-10 (VHI-10) were performed pre- and postoperatively at 1, 3, and 6 months. Stroboscopic examination evaluated normalized mucosal wave amplitude (NMWA). Parameters were compared between both groups. RESULTS: Thirty patients were analyzed (3-day group, n = 18; 7-day group, n = 12). Jitter, shimmer, and VHI-10 were significantly better in the 3-day group at 1 month post operation. GRBAS was significantly better in the 3-day group at 1 and 3 months post operation, and NMWA was significantly better in the 3-day group at 1, 3, and 6 months post operation compared to the 7-day group.

The main goal of this research was to examine the influence of the educational level and employment of parents on the development of phonological awareness of pupils of first and second primary school grades. The sample of respondents consisted of a total of 70 students whose age ranged from 78 months to 104 months. Observing respondents in relation to gender, 37 were male and 33 were female. The research was conducted in primary schools in the municipalities of Travnik and Novi Travnik in Bosnia and Herzegovina. The obtained results showed that the level of parents' education and the employment of parents influence the development of the phonological awareness of pupils of the first and second grades of primary schools. Namely, phonological awareness was more developed with pupils whose parents were employed and had a higher education level. The obtained results point to the need for professionals to pay more attention to the phonological development of children coming from families of low socioeconomic status. It is very important to timely identify students with difficulties in the development of phonological awareness with the aim of organizing and providing adequate professional assistance. If the student has difficulty in the field of phonological awareness, in that case the mentioned difficulties may also have a negative effect on the learning skills in other areas.

Introduction: Malocclusion as an oral disorder can cause negative impact on individuals oral conditions, social interactions and self-esteem. Aim: The aim of this study was to compare oral health-related quality of life (OHQoL) of patients who had received fixed orthodontic treatment and patients who had not received fixed orthodontic treatment. Materials and Methods: Data were collected from 178 participants attended at professional dental office (mean age 22.71 years) in two groups (experimental and control). The experimental group comprised of 90 subjects who were in the retention phase, after their orthodontic treatment, and the control group comprised of 88 untreated subjects. Oral Health Impact Profile (OHIP-14) was used to assess the patients oral health related quality of life (OHQoL). Results: The control group had significantly higher OHIP-14 scores than experimental group (p < 0.001). Participants with treatment need reported a significantly greater negative impact on the overall OHRQoL score. Conclusion: Subjects with no history of orthodontic treatment had more negative oral health related quality (OHRQoL), than subjects who had completed orthodontic treatment. Dental malocclusion has significant negative impact on OHRQoL.
