Abstract: The main purpose of this study was to examine the incidence (frequency) and stuttering severity in the school-age children with Down syndrome. The sample was consisted of 37 school-age children with Down syndrome, both male and female. The study was conducted in the following institutions: Institute of Special Education and Rehabilitation for Children with Intellectual Disabilities "Mjedenica"; Centre for Education, Training and Employment of Mentally Retarded Children, Children with Autism and Cerebral palsy "Vladimir Nazor" in Sarajevo; Primary School of Special Education Zenica“; Primary school "Kova i i" Sarajevo; "Association of United Civic Actions – DUGA" in Sarajevo; and The Association "Be my friend" in Ilija . All of the subjects were individually examined. The results showed that 13,51 % of the children with Down syndrome stuttered, and the total result of stuttering severity indicates a moderate stuttering. These results show that children with Down syndrome should be enrolled intensively in speech therapy in order to help them overcome their stuttering, to facilitate their everyday communication and to teach them how to cope with stuttering.

Abstract: Along with the current processes of restructuring of Energy power system of Bosnia and Herzegovina, liberalisation of the electricity market, and modernisation of the existing power plants, Bosnia and Herzegovina must turn to the utilisation of renewable resources in reasonable dynamics as well. Respecting this policy, the initial evaluation of the potential of renewable energy resources in Bosnia and Herzegovina is performed. The methodology of evaluation of wind energy utilisation is presented in this paper, as well as some other aspects of utilisation of the renewable energy resources in Bosnia and Herzegovina. Implementation of selected projects should improve sustainability of energy power production in Bosnia and Herzegovina, by reducing the total emission of carbon dioxide originated from energy power system of Bosnia and Herzegovina.
Cognitive-Behavioral Therapy and Neuroscience: Towards Closer Integration
Nata?a Joki?-Begi
Psychological Topics , 2010,
Abstract: The aim of this review article is to provide an integrative perspective by combining basic assumptions of cognitive behavioral therapy (CBT) with neuroscience research results. In recent years, interdisciplinary research in the field of neuroscience has expanded our knowledge about neurobiological correlates of mental processes and changes occurring in the brain due to therapeutic interventions. The studies are largely based on non-invasive brain imaging techniques, such as functional neuroimaging technologies of positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). The neuroscientific investigations of basic CBT hypotheses have shown that (i) functional and non-functional behavior and experiences may be learned through lifelong learning, due to brain neuroplasticity that continues across the entire lifespan; (ii) cognitive activity contributes to dysfunctional behavior and emotional experience through focusing, selective perception, memory and recall, and characteristic cognitive distortion; on a neurobiological level, there is a relationship between top-down and bottom-up regulation of unpleasant emotional states; and (iii) cognitive activity may be changed, as shown by therapeutic success achieved by metacognitive and mindfulness techniques, which also have their neurobiological correlates in the changes occurring in the cortical and subcortical structures and endocrine and immune systems. The empirical research also shows that neurobiological changes occur after CBT in patients with arachnophobia, obsessive-compulsive disorder, panic disorder, social phobia, major depressive disorder and chronic fatigue syndrome.disorder and chronic fatigue syndrome.

Journal of Thermodynamics , 2014, DOI: 10.1155/2014/231296
Abstract: A numerical procedure for deriving the thermodynamic properties , , and of the vapor phase in the subcritical temperature range from the speed of sound is presented. The set of differential equations connecting these properties with the speed of sound is solved as the initial-value problem in domain . The initial values of and are specified along the isotherm with the highest temperature, at a several values of [0.1,?1.0]. The values of are generated by the reference equation of state, while the values of are derived from the speed of sound, by solving another set of differential equations in domain in the transcritical temperature range. This set of equations is solved as the initial-boundary-value problem. The initial values of and are specified along the isochore in the limit of the ideal gas, at several isotherms distributed according to the Chebyshev points of the second kind. The boundary values of are specified along the same isotherm and along another isotherm with a higher temperature, at several values of . The procedure is tested on Ar, N2, CH4, and CO2, with the mean AADs for , , and at 0.0003%, 0.0046%, and 0.0061%, respectively (0.0007%, 0.0130%, and 0.0189% along the saturation line). 1. Introduction The speed of sound is the property of a fluid which is measured with an exceptional accuracy (Ewing and Goodwin [1], Estrada-Alexanders and Trusler [2], Costa Gomes and Trusler [3], Trusler and Zarari [4], and Estrada-Alexanders and Trusler [5]). While the speed of sound itself is a piece of useful information about a fluid, other thermodynamic properties like the density and the heat capacity, which may be derived from it, make the speed of sound even more useful. However, the speed of sound in a fluid is connected to these properties through the set of nonlinear partial differential equations of the second order. The general solution to this set of equations has not been found yet, except for the gaseous phase under low pressures (Trusler et al. [6] and Estela-Uribe and Trusler [7]). At moderate and higher pressures a procedure based on the numerical integration may be used for obtaining the particular solution (Estrada-Alexanders et al. [8] and Bijedi? and Neimarlija [9–11]). The main disadvantage of this approach is the need for the initial and/or the boundary values of the quantities being calculated (the Dirichlet conditions) and their derivatives with respect to an independent variable (the Neumann conditions). In the previous paper (Bijedi? and Neimarlija [11]) it was shown that the compressibility factor and the heat capacity of a

Abstract: There are different forms of teaching using ICT, and they differ according to the level of technological support, the role and tasks of the participants, the level of students’ participation, the physical location of the participants and their interaction. Distance learning is the common name for the process of obtaining knowledge and skills with the assistance of ICT and other forms of distance study. E-learning is a special form of such teaching. In terms of the teaching materials’ specific qualities, and the recommendation of teaching methods for successful teaching, there are different options for applying e-learning in teaching. E-learning can be used either as an independent form of teaching, or as a support to the already established systems of education, or even as their addition. The problem that is being solved in this paper is the prioritisation of e-learning forms for the specific teaching unit, subject, group of subjects, or the whole teaching programme. All this should be done regarding the context, which is characterised by the quality and innovative teaching, available professionals, equipment, possibility of students’ approach to technology, organization of teaching, and rules and regulations. This problem was solved with the assistance of AHP models developed in the process of group decision making supported by sw TeamEC2000.

Abstract: The material considered in this study, SnO2 (110), has a widespread use as gas sensor and oxygen vacancies are known to act as active catalytic sites for the adsorption of small mo-lecules. In the following calculations crystal line SnO2 nano-crystal have been considered. The grains lattice, which has the rutile structure of the bulk material, includes oxygen vacancies and depositing a gaseous molecule, either ethanol, above an atom on the grain surface, generates the adsorbed system. The conduc-tance has a functional relationship with the structure and the distance molecule of the na-no- crystal and its dependence on these quanti-ties parallels the one of the binding energy. The calculations have quantum mechanical detail and are based on a semi-empirical (MNDO me-thod), which is applied to the evaluation of both the electronic structure and of the conductance. We study the structural, total energy, thermo-dynamic and conductive properties of absorp-tion C2H5OH on nano-crystal, which convert to acetaldehyde and acetone.

Abstract: In the paper the possibility to use mathematical models and statistical techniques in strategic planning and decision making about e-learning is presented. Strategic planning and decision making has been covered as consisting of four phases: (1) intelligence, (2) design, (3) choice and (4) implementation. Each of the phases will be described in this paper, but the accent will be put on the statistical evaluation of the results of the questionnaire which was based on the developed theoretical model for decision making about e-learning implementation in the higher education sector. In general, the main objectives of this paper are: (1) validation of the first theoretical model for decision making about e-learning implementation in the higher education sector, by means of factor analysis and (2) reduction of a large number of variables to a smaller number of factors, i.e. designing the improved theoretical model, for modelling purposes (developing AHP & ANP models).

Abstract: Objective. To determine the reliability of transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) in predicting the size of an atrial septal defect (ASD). Material and methods. The study included 16 patients who underwent the catheter-based procedures to close an atrial septal defect between February 2008 and December 2011 at the Paediatrics Clinic, CCU Sarajevo, after clinical and TTE and TEE evaluation. In order to determine the assumed diameter of the balloon (A-SBD), we used the formula of quantificationA-SBD=TTE defect diameter×1:09 + 3.9 mm and A-SBD=1.1× transesophagealdiameter of ASD+2.0 mm. The ASD was examined using the long-axis view, the basal short-axis view, the apical four-chamber view and the subcostal view to observe its position, diameter and relationto neighbouring structures. The largest diameter was selectedas the reference diameter. Results. Of the total number of treatedpatients, 11 were female. Treatment was conducted by a foreign andlocal team of invasive cardiologists. The average age of the patientswas 8.43 years (2 -17 years). Apart from a transient disturbance ofrhythm in the youngest patients, there were no other intra and postprocedural complications. The obtained formulas represent “our” default size of the SBD, based on measurements of TTE and TEE: A-SBD(TTE)=6.02+0.86×TTE and A-SBD (TEE)=3.93+0.86×TEE. Conclusion.ASD diameter determined by TTE and TEE can reliably determinethe appropriate size needed Amplatzer Septal Occluder device.

Abstract: Aim To determine if short-term changes in sex hormones (such as cyclic changes within the menstrual cycle) can influence the serumconcentration of soluble cell adhesion molecules (CAMs).Methods Sixteen healthy young women with normal cycles participated in this study. Serum levels of sICAM-1, sVCAM-1 and E-selectin were determined in three different phases of the menstrual cycle: a) early follicular (EF) phase, b) ovulatory (O) phase and c) midluteal (ML) phase, by standardized ELISA-based kits. To confirm the exact assessment of menstrual cycle phases, serum levels of estrogen, progesterone, LH and FSH were measured. Results There were significant oscillations in serum female sex hormones concentration over the cycle duration, as expected the level of estrogen (E2) and progesterone (PROG) was the lowest in EF phase, the highest E2 appeared in O phase, and both E2 and PROG were present in high concentrations during ML phase. There was a significant positive correlation between E2 and serum soluble ICAM -1 concentrations (p=0,041, correlation coefficient 0,306). However, there was no significant change in other soluble CAMs concentration during the menstrual cycle. Conclusion Results of our study suggest that short-term changes in female sex hormone levels could modulate expression of soluble ICAM-1, but not VCAM -1 or E-selectin in extent that would affect a young woman’s health.

Abstract: Aim To investigate the cystatin C levels in sera of patients with aggressive non-Hodgkin B-cell lymphoma. Methods The levels of cystatin C in sera of lymphoma patients and control group consisted of healthy individuals, were measured by using speciic sandwich-type ELISA. For each patient the clinical stage of disease was determined according to Ann Arbor staging system for lymphomas. Results Our study shows that mean cystatin C serum level in the patients group (1056 ± 65 ng/mL) was signiicantly higher when compared with the mean level of the healthy control group (819 ± 28 ng/mL) (P=0,001). Mean cystatin C level of the group with clinical stages III and IV (1255 ± 109 ng/mL) was signiicantly elevated when compared with the mean level of the group with clinical stages I and II (896 ± 51 ng/mL) (P=0,03). Conclusion This inding points out a connection between inhibitor level and aggressive behaviour of lymphoma and could be considered for further strategies of prognosis of the disease.
