Traditional art of building in Bosnia and Herzegovina comprises brick or stone masonry structures. Most historical buildings belonging to national cultural heritage were made of stone-masonry. The country is situated in seismic active region of South-East Europe. In the case of strong earthquake motion such buildings could suffer heavy damages. Some structural elements of historical buildings, as domes and arches, cracked already by moderate earthquake but without the loss of stability. Substantial damages were caused by recent war disaster. Damages could be accumulated through the history as well. Generally, stone-masonry buildings in Bosnia and Herzegovina can be classified in vulnerability classes between A and C according to European Macroseismic Scale. Design and construction procedures for rehabilitation are presented here with examples of repair and strengthening of mosques, which present historical stone masonry structures dating from the Ottoman period in Bosnia and Herzegovina. Traditional and contemporary materials were used for their rehabilitation. It is important to preserve original forms, especially those of damaged elements. The challenge for structural engineers and architects was to find equilibrium between aesthetical and structural demands.

The main objective of this study was to investigate the correlation between the indoor and outdoor ambient dose equivalent rates measured by the ion chamber inside and around the historical sacral objects at a few locations in Bosnia and Herzegovina. The investigated objects made of the traditional building materials were built in the Late Medieval, Post Medieval, and Ottoman Period of Bosnia and Herzegovina history. The LUDLUM Model 9DP instrument based on a pressurized ion chamber was selected for natural low level radiation measurements since the ionisation chambers have higher sensitivities than the other types of detectors. The detection capability of the LUDLUM Model 9DP pressurized ion chamber was examined in the laboratory conditions with a source of low activity and under natural environmental radiation conditions by measuring the indoor and outdoor dose rates. A weak positive correlation was found between the ambient dose equivalent rates inside the historical sacral objects and the dose rates outside the objects. The average evaluated value of the indoor to outdoor dose rate ratio of 1.07 for the studied historic objects is less than that obtained for the contemporary building materials such as concrete. No study on the indoor to outdoor dose rate ratio in Bosnia and Herzegovina measured by the LUDLUM 9DP dose rate meter based on an ion chamber has been conducted yet. In addition to direct measurements, the first gamma spectrometric analysis of a few samples of building materials from the Late Medieval period in Bosna and Herzegovina was performed. The results of the gamma analysis revealed almost uniform distribution of primordial radionuclides in the investigated samples. It was demonstrated that such materials had the reduced content of radioactive isotopes compared to the contemporary building materials and therefore they could have potential advantages in specific applications related to the environmentally sustainable architecture.

In this paper we presented Robert Sternberg’s ”Straight-A” model of human creativity. It is constructed out of fve elements - overlapping phases – respectively most affecting variables in the creative process: (1) Activators-deactivators, (2) Abilities, (3) Amplifers-attenuators, (4) Appeal to audience and (5) Assessment by audience. The prerequisite of creativity is acting of individuals and their environment, during the all five above-mentioned phases, in the same / right (straight) direction. But, this is rarely the case, so the creative process does not complete itself often. For example, at phase one there are not only activators, at phase two the interaction and synergy of different intellectual abilities stay away etc. Psychologically, based on clear validity indicators, this model (for now) plays a theoretical role and has potential for heuristic generativity. It requires systematic empirical review, especially in the felds of internal and external construct validity.

The fair and reliable financial reporting of business entities is extremely im portant for strengthening the confidence among business entities, acting po sitively on the scope of business activities and achieved results. On the other hand, individuals, businesses and the entire society, suffered huge losses, due to the frauds in financial reports, by dropping the confidence in the accoun ting profession. The public’s expectations from the accounting profession are that its professionals consciously reject participation in any fraud activities, and be real fighters for the real financial reporting of the entities. In the light of specified expectations, this paper tries to consider the ability of students of economic specialization in Bosnia and Herzegovina in recognizing cases of false financial reporting among different situations that can(not) include fraud characteristics, and their readiness to take active participation in the fight against frauds in business entities and economic crimes, in general. The results of the research showed that research participants clearly recogni ze cases of false financial reporting among various fraudulent activities, that they have a high level of awareness regarding the seriousness of the fraud type and its negative consequences for entities, and that they express their unreserved readiness to report these cases to the competent authorities with the purpose of prosecution.

Lindström – Gessel – Viennot theorem connects linear algebra and combinatorics with graph theory. We will present proof of LGV theorem and its application on Cauchy – Binnet and generalized Cauchy – Binnet formula as well as calculation of binomial determinants and some other specific determinants.

The bilingualism of deaf and hard of hearing children implies the knowledge and regular use of sign language, which is used by the community of deaf people, and of spoken language, which is used by the hearing majority. At preschool and school age, it is necessary to allow children to continue adopting the language that they started in the family (either sign language or spoken language). Children will adopt both language modalities best through interactions with other fluent speakers. Results of numerous studies indicate that the best approach in the process of development of speech and language and the education of the deaf and hard of hearing children is the bilingual approach. The aim of this approach is to develop communication skills in children, to provide a higher level of education for them, and to include them in the life of the community. It is necessary to improve the existing education system in the direction of developing a kind of a model that will re1 122tamara@gmail.com 2 ljubicaisakovic07@gmail.com 3 radomir.arsic@pr.ac.rs The paper is from the Project of the Ministry of Education, Science and Technological Development of the Republic of Serbia entitled Тhe Effect of Cochlear Implantation on the Education of Deaf and Hard of Hearing Persons, No. 179055.
