The future 5G wireless infrastructure will support any-to-any connectivity between densely deployed smart objects that form the emerging paradigm known as the Internet of Everything (IoE). Compared to traditional wireless networks that enable communication between devices using a single technology, 5G networks will need to support seamless connectivity between heterogeneous wireless objects and IoE networks. To tackle the complexity and versatility of future IoE networks, 5G will need to guarantee optimal usage of both spectrum and energy resources and further support technology-agnostic connectivity between objects. One way to realize this is to combine intelligent network control with adaptive software defined air interfaces. In this paper, a flexible and compact platform is proposed for on-the-fly composition of low-power adaptive air interfaces, based on hardware/software co-processing. Compared to traditional Software Defined Radio (SDR) systems that perform computationally-intensive signal processing algorithms in software, consume significantly power and have a large form factor, the proposed platform uses modern hybrid FPGA technology combined with novel ideas such as RF Network-on-Chip (RFNoC) and partial reconfiguration. The resulting system enables composition of reconfigurable air interfaces based on hardware/software co-processing on a single chip, allowing high processing throughput, at a smaller form factor and reduced power consumption.

Cooperative learning is a modern teaching strategy in which team work and cooperation become the most important activities of the entire teaching process. The quality of interaction between students and teacher, as main participants in teaching process, is important for successful application of cooperative learning. Beside faster and longer lasting knowledge acquiring, cooperative learning develops critical and creative thinking, communication and social skills and it strengthens self-confidence. Modern methods of teaching mathematics focus on didactical principle of conscious activity above other principles. This means students are major, active factors of mathematics teaching, and not only they participate in the process of teaching, but they also participate in the selection of methods of teaching. This enhances their motivation for work during classes. This means, what is learned through cooperative learning is better used in new situations, knowledge transfer is greater and new knowledge is acquired easier and lasts longer. Specific and abstract contents of mathematics lead to different ways of applying cooperative learning in this subject. That is why we chose this subject, i.e. to explore and point out the possibilities and ways of applying cooperative learning in mathematics.

Introduction: The purpose of this study was to validate Bosnian translation of disease specific quality of life measure MSQoL-54 which is widely used in practice. Material and Methods: Previously translated and culturally adopted MSQoL-54 questionnaire used in this study has been provided and licensed by Optum Inc. The questionnaire was validated in 62 MS patients seen at Neurology clinic at University Clinical Center Sarajevo, during April 2016 until May 2016. Internal reliabilities of Bosnian version MSQoL-54 were assessed for multiple item scales by using Cronbach’s alpha coefficient. Clinical validity was assessed comparing means of the two summary MSQoL-54 scores by the EDSS score. Pearson’s (r) correlation coefficient was used to investigate the relationship between the composite scores and the main clinical and demographic variables. Results: Patients’ participation was satisfactory and all scales fulfilled the usual psychometric standards. Highly significant inverse relationship was found between both composite scores and clinical characteristics of the disease and the EDSS. The lowest internal consistency reliability is found on social function scale (0.743), overall quality of life (0.782) and pain (0.833). The highest internal consistency reliability is found on role limitations due to physical problems (0.959), physical health (0.962) and role limitations due to emotional problems (0.966). The mean value of MSQoL-54 PHC (Physical Health Composite) and MHC (Mental Health Composite) were 49.82±18.90 (36.05-61.38) 51.84±22.22 (34.93-70.20) respectively. Our study has shown that the Bosnian version of MSQoL-54 is easy to administer and well accepted by patients and may be useful as clinical outcome measures in patients with MS.

β-Glucosidase was purified from Brassica oleracea by salting out with ammonium sulfate and hydrophobic interaction chromatography. Results demonstrated that the enzyme is a dimer (130 kD) made up of one major (80 kD) and one minor subunit (50 kD). The pH optimum is 6.0, with 50% of the enzyme's original activity remaining between pH 4.0 and pH 7.0. The temperature optimum is 35C, and activity did not decrease after two hours of exposure to this temperature. The activity of the enzyme was investigated on four substrates, 4-Nitrophenyl β-D-glucopyranoside (p-NPG), ortho-Nitrophenyl-β-D-glucopyranoside (o-NPG), para-Nitrophenyl-β-D-galactoside (p-NPGal) and ortho-Nitrophenyl-β-D-galactoside (o-NPGal), and km values were shown to be 0.755 mM, 0.174 mM, 0.988 mM and 0.213 mM, while Vmax values were 604 U/mg, 38 U/mg, 556 U/mg and 308 U/mg, respectively. The enzyme is completely inhibited by gluconolactone and glucose against p-NPG as substrate, with ki values of 0.038 mM and 0.64 mM, respectively. To our knowledge, this is the first study demonstrating purification and characterization of β-glucosidase from broccoli, thus providing a better understanding of its role in the plant, and establishing a basis for further research. Practical Applications To our knowledge, this is the first study demonstrating purification and characterization of β-glucosidase from broccoli, thus providing a better understanding of its role in the plant, and establishing a basis for further research. The results of this research highlight the potential of the enzyme isolated from broccoli for further research. Succeeding efforts would involve optimization of this procedure for increasing the enzyme yield, in order to make it a viable candidate for industrial application.

Objective: Irrational use of antimicrobials is a major driver of antimicrobial resistance, exacerbated by dispensing antibiotics without a prescription. Our previous study suggested this was a problem in the Republic of Srpska despite legislation. Since then, a number of activities have been initiated. Consequently, the study aimed to ascertain whether these multiple initiatives had reduced this. Methods: Patients visiting all community pharmacies in the Republic from October 2014 to July 2015 presenting with symptoms typical of an acute, viral, and mostly uncomplicated upper respiratory tract infection, with results compared to the previous study. If an antibiotic was suggested, the maximum allowance was €3/pack. Findings: Self-medication with antibiotics significantly decreased from 58% to 18.5% of pharmacies. In both studies, most patients were offered over-the-counter medication. The most common reason for not dispensing an antibiotic was “antibiotics can be dispensed with a prescription only.” The penicillins were the most dispensed antibiotic. Fewer patients than the previous study were given instructions about antibiotic use and no discussion on their side effects. Conclusion: While encouraging that self-medication decreased significantly, 18.5% were disappointing given recent initiatives. Fewer instructions about antibiotics if an antibiotic was dispensed were also disappointing. This suggests the need for even stronger enforcement of the laws as well as further training of pharmacy personnel to ensure the future appropriate use of medicines.

Introduction: Tonsillectomy is a frequently used, low-risk surgical procedure. The post-tonsillectomy haemorrhage occurs rarely, but is a life-threatening complication. Some studies show that the surgical technique affects the haemorrhage rate. Aims: To analyse the post-tonsillectomy haemorrhage rate, and to determine whether the effect of the surgical technique on the haemorrhage rate exists. Methods: We retrospectively reviewed data of all patients who underwent a tonsillectomy in three regional ENT departments in Bosnia and Herzegovina (Tuzla, Zenica and Bihac) between January 1st 2015 and October 31st 2016. Disorders which could affect the post-tonsillectomy haemorrhage rate were excluded. Tonsillectomy techniques used in these three centers were the hot technique (monopolar/bipolar forceps dissection and haemostasis) and the combined technique (cold steel dissection with monopolar/bipolar forceps haemostasis). Results: 1087 patients that underwent a tonsillectomy were analysed in this study. 864 (79.48%) of those were children. 922 (84.82%) patients were operated using the combined technique, 165 (15.17%) underwent a tonsillectomy using the hot technique. Post-tonsillectomy haemorrhage occured in 46 (4.23%) patients. 45 (4.88%) patients had a postoperative haemorrhage after tonsillectomy using the combined technique, whereas haemorrhage occured in 1 patient (0.6%) after using the hot technique. The haemorrhage rate was about eight times lower after tonsillectomy using the hot technique (p=0.012). Conclusion: We conclude that the surgical technique used for tonsillectomy and adenotonsillectomy with the lowest post-tonsillectomy haemorrhage rate is the hot technique; these results are statistically significant. This technique should be used whenever possible, in order to lower the risk of post-tonsillectomy haemorrhage.
