Background: For many years, pharmacy and medicine were inseparable sciences, so everything that was done in the field of medicine, that is, treatment, can be related to pharmacy. The history of pharmacy therefore also includes the history of medicine, at least until the 13th century, when pharmacy was officially separated from medicine. Objective: The aim of this study was: to describe the books and monographs that are available on the Internet, which deal with the study of the history of Pharmacy; and to show pharmaceutical history museums around the world and their unique collections of pharmaceutical artifacts. Methods: During the preparation of this paper, a descriptive method of analysis from the available literature was used. The analysis of available literature included professional books, monographs, articles and other literature available on online browsers. Results and Discussion: Today there are a large number of societies, academies, associations and foundations dealing with the history of pharmacy. Also, a lot of books, monographs and scientific papers published in on-line databases. The goal of each organization is the research of historical facts in the field of pharmacy and medicine that will be shared with professionals, but also persons who are not from the profession (doctors, librarians, archaeologists, archivists). A large number of museums have been opened for the history of pharmacy, and almost every developed country has such a museum. Such museums represent a national treasure, because they preserve the valuables of pharmacy from the territory of the country, as well as the world.

Background: The rich history of pharmacy in Bosnia and Herzegovina has been sporadically dealt with systematically, except by enthusiasts and researchers. The only book on this topic was published in 1958, and after the aggression against Bosnia and Herzegovina, the history of pharmacy was treated mainly as part of the history of medicine. The lack of a culture of memory and a systematic approach to historical heritage brought together a group of experts who deal with this topic in more detail and collect available historical relevant material. Pharmacy as a highly regulated health discipline also in Bosnia and Herzegovina is a legacy of legal acts and documents that depict different periods and the development of pharmacy itself under the influence of circumstances and legislation. Objective: The aim of this paper is to show the development of legislation related to the pharmaceutical sector in Bosnia and Herzegovina through the historical periods of its development. Methods: This is retrospective research based on internet sources, archives and publications available in libraries. Results and Discussion: The available legal regulations and documents through five periods of pharmaceutical development were analysed, from which it can be concluded that the organization of the pharmaceutical industry and its development over time remained stricter. Legal regulations depict the role of pharmacy in the health system, but they also represent sources for further research in this area, and constitute important historiographical material. The analysis of legal regulations speaks volumes about the way pharmaceutical activity is organized, so it is possible to follow the appearance of the first pharmacies, pharmacists, requirements for the quality of medicines, production and the modern role of pharmacists in the health system. Pharmaceutical legislation will certainly be the subject of future negotiations on the accession of Bosnia and Herzegovina to the European Union, and harmonization with the acquis of the EU is expected in the coming period.

Optical time-domain reflectometer (OTDR) has long been and is still considered the main test tool for characterizing fiber optic links, i.e. identify and localize refractive and reflective events such as breaks, splices and connectors, and measure their insertion/return loss. Specifically, sufficient dynamic range and thus alike signal-to-noise-ratio (SNR) enable clear far-end visibility even of long fiber links. Moreover, under such conditions, the highest achievable optical bit-error-rate (BER) floor is to the large extent determined by major reflective events such as the specific trace distortion caused by connectors and splices, each with significant return loss. Realizing this has provided the opportunity window to extend the standard OTDR capabilities list by the appropriate trace postprocessing to predict the BER floor. Accordingly, considering the SNR high, and thereby the inter-symbol interference dominant error generating mechanism, we applied the time-dispersion channel model that determines the BER floor by the rms delay spread of the (fiber) channel power-delay profile. We verified the BER floor prediction in the exemplar practical test situation, by measuring the actual BER on the same fiber link, and found the obtained values well matching the OTDR based predicted ones. Furthermore, when no dominant reflective events are identified on the OTDR trace, it implies very small time dispersion allowing the OFDM symbol cyclic prefix to always prevent inter-symbol interference. This retains the CFO to solely determine the residual BER floor and vice versa, enabling indirect estimation of CFOinduced phase distortion by simple BER testing. With this regard, we abstracted CFO with the AWGN being justified by the Central Limiting Theorem to enable efficient and quite accurate short-term BER (and so CFO phase error) predictions.

In this paper, we analyze an arbitrary heterogeneous cellular network applying stochastic geometry, and propose a modified model for assessing network spectral and energy efficiency. With this regard, we recognize that, in practice, determining Signal-to-Noise-and-Interference Ratio (SINR) as the key performance indicator, requires complex field test equipment, which might not be available or affordable. Therefore, we propose here a simple model that is based on the relatively easy measurable Bit-Error Rate (BER), whose degradation caused by various impairments is considered here as if it was due to the according additive white Gaussian noise (AWGN), thus abstracting any specific non-AWGN distortion. The proposed analytical model is verified by ns3 software network simulator, whose test results are found to match the corresponding estimated values. This indicates that both spectral and energy efficiencies of small-cell networks are higher than in larger-cell networks, even more for heterogeneous two-tier networks.

COVID-19 pandemic has put traditional forms of work and education on hold for many institutions. The impact of the transition to "online" work and education mode on mental and education on mental health is particularly interesting. The primary objective of this paper was to to identify advantages and disadvantages of transition to the online work regime that were additionally exacerbated by the pandemic (managerial aspect). The secondary objective was to consider this impact on the mental health of the individuals (socio-psychological aspects). A review of the literature published so far related to the work and teaching process in the Covid-19 pandemic recommends an online regime whenever possible. The results in the labor market domain indicate that if a person is self-disciplined, does not require supervision, has clear tasks and motivation, the online regime provides a number of benefits to such an employee, and consequently to the employer. On the other hand, for people who find motivation to work primarily in contact with colleagues, require supervision, lack self-discipline, as well as for those who aspire to managerial positions, teleworking does not give favorable results. In the field of teaching, in online education, quantitative analysis shows an improved success of pupils and students, but raises the question of whether this success is backed by real knowledge. The identified health consequences for individuals exposed to long-term online interaction regimes are, primarily: burnout syndrome, isolation from friends, problems in family relationships, experience of reduced happiness at home, general poor health and lack of sleep. It is likely that this regime will continue to some extent in the foreseeable future; work organizations and educational institutions will need to implement formalized policies that take into account support for managing the boundary between work and home activities, role clarity, workload, performance indicators, technical support, facilitating networking and training for managers.

Purpose . The purpose of this study is to examine the causes of delays in road construction projects in the Benin Republic from the consultant, client, and contractor perspectives. Design/Methodology/Approach . Through construction project reports, 20 factors that could cause delays in road construction projects were identified. The factors were arranged into a questionnaire, which was distributed to three separate experts. The fuzzy PIPRECIA (PIvot Pairwise RElative Criteria Relevance Assessment) method was used to calculate the independent importance of each delay factor. The Spearman and Pearson correlation coefficients were used to test the method’s consistency. Findings . The top five road construction project delays in the Benin Republic, according to the analysis of the 20 factors considered, are project funding, slowness during the client-endorsed payment process, scarcity of professional personnel, delay in indemnifying reimbursement (land-owners), and price escalation. This shows that of the various types of delays, the financial delay group is the most crucial. Originality/value. This study evaluates the causes of delays in road construction projects in the Benin Republic for the first time in literature. This study also examined the top 5 delay factors in road construction projects. This study is based on reports from road construction projects and a performed questionnaire survey. Based on the findings, measures have been formulated to aid project managers to alleviate the road construction delays in the Benin Republic. In addition, this study is practical for both scholars and road construction parties and provides a complete and verifiable analysis of the progress of a road construction project to make it easier and attain a competitive level of time, cost, and quality for successful road construction.

The aim of this research was to examine the frequency of different barriers faced by special education teachers in working with children with autism spectrum disorders (ASD). The sample included 53 participants of both genders and of different ages who were diagnosed with ASD. The instrument used to assess the presence of barriers in teaching refers to the Assessment of Barriers in Teaching (VB-Mapp Barriers Assessment -Sundberg, 2008). In our sample, it was found that all respondents have a pronounced presence of teaching barriers, while the most frequent barriers are prompt dependence, generalization difficulties, socialization problems, escape or avoidance of given tasks and the absence of the tact ability. Having in mind the obtained results, it is highlighted as a necessity to develop an approach that would lead to elimination of the mentioned barriers, as well as to develop a treatment plan to address those teaching barriers in working with children with PSA and consequently enable a higher degree of adoption of new knowledge and skills by children with ASD.

On islands and in island communities, especially smaller and more isolated ones, epidemics were often of greater intensity and left more significant consequences than on the mainland. The unique characteristics of an island (size, remoteness, isolation, small population size, and several manageable access points) affect the transmission of mainland epidemics and their frequency. The current global COVID-19 pandemic is an opportunity to investigate how the infection and epidemiological measures affected the life and death of island communities. The pandemic has brought mass death into our daily lives and altered the way people grieve, commemorate and remember their deceased. This paper presents the experiences and feelings of people during the COVID-19 pandemic on Croatian islands, with a focus on death, funerals, mourning, and the loss of family members. Due to the impossibility of carrying out the usual practices related to the funeral because of COVID-19 restrictions, the process of mourning and dealing with the loss of loved ones was difficult. Island communities accepted the new rules and adapted to the new circumstances but indicated that island-specific and more flexible crisis management should be applied during this health crisis. Some epidemiological measures, such as social distancing, internal island travel restrictions, and reduced gatherings, were highlighted by islanders as challenging and sometimes unnecessarily strict for some islands and their specific situations. For family members of those who died from COVID-19, additional factors and challenges have complicated their loss. Digital and social media were used to connect people and helped in coping with mourning in solitude and isolation. In this global pandemic, island communities responded to the impact of pandemic crises and adapted to new circumstances of the “new normal”.
