Poremećaji hoda i poremećaji ravnoteže uobičajeni su klinički problemi za starije osobe. Uzroci poremećaja hoda su individualni, često zbog fiziološkog procesa starenja i somatskih bolesti. Poremećaji hoda dovode do gubitka lične slobode, pada i povreda i rezultiraju značajnim smanjenjem kvaliteta života. Kod starijih osoba, kontrola statičke i dinamičke kontrole položaja i ritma je poremećena, što dovodi do izmijenjenog hoda, smanjuje se korak, povećava se širina hoda kako bi se održala ravnoteža, gornji dio tijela se savija prema naprijed da bi se održala ravnoteža, ruke se ne pomiču dok hodaju, hod je nepravilan, teže je započeti prve korake nakon sjedenja ili stajanja, kao i okretanja. Ako je moguće, najbolje je tretirati etiološki faktor, tj. osnovne bolesti, kao što su parkinsonizam, neki metabolički poremećaji itd. Treba voditi računa o nusefektima nekih lijekova, naročito antiparkinsonika, sedativa, hipnotika i antidepresiva. Također je potrebno uključiti i druge specijaliste, kao što su reumatolozi, fizijatri i fizioterapeuti, kao i internisti, kardiolozi i dijabetolozi. Kognitivne strategije također mogu biti korisne, na primjer usmjeravanje pažnje na svaki pojedinačni korak, a ne čin hodanja kao takav, svjesno pokušavajući napraviti pojedinačne velike korake, ili mentalno brojanje, kao i upotreba pomagala za hodanje.

SAŽETAK: Uvod: Alergija na hranu je u zadnjih 20 godina postala značajan zdravstveni problem. Prevalencija se kreće od 3-38% samoprijavljenih slučajeva, odnosno od 1-7% dijagnosticiranih slučajeva alergije. Zadnjih godina su poduzeti brojni projekti kako bi se odredila prevalencija, vrsta alergena, uzroci alergija, veza sa ostalim zdravstvenim problemima, načini dijagnosticiranja, provođenje kontrole rizika u prehrambenoj industriji, prilagođavanje zakonske regulative potrebama alergičnih osoba itd. Dok su neke države uradile mnogo po ovom pitanju, još uvijek je veliki broj onih koji nemaju podataka o alergijama na hranu na svom području, a takva je situacija i u BiH. Cilj rada: Utvrditi prevalenciju alergija na hranu iz anketnog ispitivanja u Kantonu Sarajevo. Utvrditi kakva je učestalost nekih drugih alergija kod ispitanika. Materijal i metod rada: Ovo presječno istraživanje o alergiji na hranu provedeno je tokom marta i aprila 2017. među stanovnicima Kantona Sarajevo oba spola i svih dobnih skupina metodom slučajnog uzorka. Posebno dizajniran anketni upitnik od 16 pitanja popunilo je 480 ispitanika. Istraživanje je provedeno retrospektivno. Rezultati: Rezultati ankete provedene na području Kantona Sarajevo pokazuju procenat od 51% osoba koje prijavljuju da imaju neku vrstu alergije, među njima je 20% prijavljenih alergija na hranu, odnosno 11,7 % slučajeva dijagnosticiranih alergija na hranu, a u odnosu na ukupan broj od 480 (100%) ispitanika koji su učestvovali u anketi. Najčešće prijavljeni alergeni su: mlijeko i mliječni proizvodi, žitarice, jaja, kikiriki, orašasti plodovi, riba (sa školjkama i rakovima) i jaja. Zaključak: Dobiveni rezultat prevalencije alergije na hranu u našem istraživanju u ukupnom ispitanom uzorku od 480 anketiranih, njih je 96 (20%) ispitanika što ukazuje da je problem alergija na području Kantona Sarajevo značajan, i da se učestalost kreće u vrijednostima koje su karakteristične i za druge regije Evrope i svijeta. Zakonska regulativa se redovno usklađuje sa pravnom tekovinom Evropske unije, ali postoji nedostatak lako dostupnih informacija, koje bi alergičnim osobama olakšale proces dijagnosticiranja, preveniranja kontakta sa alergenima i snalaženje u svakodnevnom životu.

In general, the mixing the reactants is very important to the process and the rate of combustion of each fuel, especially low-ranked coals with low reactivity. The appropriate excess air coefficient for combustion and the position and mode of supply of individual portions (air sta- ging) of the total air in the furnace are one of the key influ- encing factors for the mixing, respectively the efficiency of the combustion process, and the level of emissions. Today, the air staging (primary, secondary, tertiary and over fire air-OFA) is an indispensable process in the design of new industrial and energy boilers. Also, this measures are used for the reconstru- ction of existing furnace of large boilers. The implementation of this primary measure in the furnace does not require signi- ficant financial resources - the costs of investing in the intro- duction of air staging supply for combustion in the furnace are very low in relation to the multiple positive effects and bene- fits of such a system, especially a lower NOx emissions. However, the first condition for the correct and reliable design of the air staging system in the furnace is the choice of the optimal position for the supply OFA air. Determination of this position on the furnace depends on several factors, primarily the type and characteristics of the fuel, grinding quality, co- mbustion technology, furnace structure, type, number and arra- ngement of burners. On this topic, the Faculty of Mechanical Engineering of the University of Sarajevo, in the Laboratory for Coal and Biomass Combustion, conducted extensive rese- arch on the pulverized combustion of coal blends of the Ce- ntral Bosnia Mining Basin, including co-firing of these coals with waste wood biomass (beech and spruce sawdust). Here is presented some of the results of those NOx emission studies for different fuels and combustion temperatures, depending on the mode of supply and the positions of the combustion air supply in the boiler furnace.

Abstract Identification of dynamic networks has been a flourishing area in recent years. However, there are few contributions addressing the problem of simultaneously identifying all modules in a network of given structure. In principle the prediction error method can handle such problems but this methods suffers from well known issues with local minima and how to find initial parameter values. Weighted Null-Space Fitting is a multi-step least-squares method and in this contribution we extend this method to rational linear dynamic networks of arbitrary topology with modules subject to white noise disturbances. We show that WNSF reaches the performance of PEM initialized at the true parameter values for a fairly complex network, suggesting consistency and asymptotic efficiency of the proposed method.

Even though the Enterprise Resource Planning (ERP) technologies have been significantly addressed in managerial literature, few studies investigated the effects of digital literacy. This study aims to explore the relationship between digital literacy and ERP technology adoption in Bosnia and Herzegovina (BiH), as well as the mediating effects of business innovativeness within that relationship. A valid and reliable structured survey has been prepared and delivered to companies in BiH which use ERP technologies. Based on the recent literature, first order structural equation model has been proposed and tested. The empirical data was based on 82 questionnaire responses from companies in BiH which use ERP technologies. Once the data has been collected, factory data analysis has been performed to purify scales through items' loadings and Cronbach's Alpha values. The resultant scales have been tested for convergent validity through partial least-square path modelling using Smart PLS 3 software. The results indicated that effects of digital literacy on actual system use are significant and positive, and that business innovativeness partially mediates the relationship.

Summary This study assessed the potential of probiotic characteristics of bacterial strains isolated from dry-cured sheep ham. It is one of the most common autochthonous processed meat products made in a traditional way on the Pešter plateau (Western Serbia). Isolates were identified as Lactobacillus curvatus (9 strains), Lactobacillus sakei (3 strains), and Enterococcus faecium (4 strains) using MALDI-TOF mass spectrophotometry. The study of probiotic characteristics of 16 dry-cured sheep ham isolates included survival rate through the gastrointestinal tract (GI), the possibility of biogenic amine synthesis, growth on medium with different concentrations of phenol,and antimicrobial activity. The results showed that in simulated gastric juice conditions, the cell number decreased after the first hour of incubation in the tested strains of Lb. curvatus, Lb. sakei and En. faecium except in the case of Lb. curvatus IIos19 where the number of cells remained approximately the same. After the second hour of incubation, the number of cells generally remained at the level of the first hour except in the case of the following isolates: Lb. sakei Ios12, Lb. curvatus IIos18 and En. faecium IIos24, where an increase in the number of cells was noticed after the second hour of incubation. In simulated small intestine conditions, an increase in the number of vital cells after 4 and 6 hours of incubation was observed in the isolates Lb. curvatus IIos4, Lb. sakei (Ios12, IIIos13), and En. faecium Ios1a. Synthesis of biogenic amines was not observed in investigated lactobacilli and enterococci. Analyzed isolates exhibited growth on media with 0.1% and 0.2% phenol, while 5 isolates exhibited decarboxylase activity. Six Lactobacillus strains, Lb. curvatus (IIos6, IIos17, and IIIos1), Lb. sakei (IIIos16, Ios12, and IIIos13) and En. faecium Ios4 inhibited the growth of tested pathogens, including Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Listeria monocytogenes ATCC 19115, Pseudomonas aeruginosa ATCC 27853 and Bacillus cereus ATCC 14579.

Investigamos as relações possíveis entre a estética e a educação a partir de um trabalho de campo desenvolvido no primeiro semestre de 2018, numa escola municipal do município de Belo Horizonte/MG, que atende alunos e alunas com deficiência intelectual com mais de dezoito anos. A partir de uma visita técnica ao estabelecimento, coletamos informações sobre a forma de dinamização das aulas e do processo ensino-aprendizagem através da arte [oficinas de teatro, de artesanato, de dança], alicerçada pela concepção sociointeracionista de Lev Vygotsky e por diagnósticos médicos precisos para um atendimento personalizado. A partir da observação do cotidiano da escola e de sua pedagogia centrada nas atividades artísticas e culturais percebemos uma importante contribuição para a educação inclusiva na região metropolitana de Belo Horizonte/MG. A metodologia usada foi o trabalho de campo baseado na observação do cotidiano escolar em suas diversas atividades, a pesquisa bibliográfica e a geração de relatório de pesquisa com entrevistas e fotografias das atividades. Os resultados da pesquisa e da imersão no universo desta escola demonstram que a estética e a educação podem se servir mutuamente uma da outra, com ganhos expressivos na qualidade do ensino e do aprendizado.

RESUMO: As causas mais comuns de contaminações nos grandes centros urbanos estão frequentemente atreladas aos tanques enterrados em postos de gasolina. Evitar a contaminação do solo envolve o descarte adequado de resíduos ou demais materiais que representam riscos, assim o escopo proposto pelo trabalho é demonstrar os processos adotados para detectar, analisar e descartar o solo contaminado por hidrocarbonetos após a realização de obras geotecnicas de um empreendimento localizado na zona Sul de São Paulo. A liberação do material contaminado para bota-fora foi realizada através de monitoramento por meio de medidores de gases indicando os aspectos qualitativos das amostras. Os medidores auxiliaram na seleção dos horizontes de solos mais contaminados para coletar as amostras, seguindo os procedimentos NBR 15492 (2007) para análises quantitativas laboratoriais dos compostos químicos, sendo que a determinação das amostragens, acondicionamento ABSTRACT: The most common causes of contamination in large urban centers are often linked to the buried tanks of gas stations. Avoiding soil contamination involves the proper disposal of residues or other materials that represent risks, so the scope proposed by the work is to demonstrate the processes adopted to detect, analyze and discard hydrocarbon-contaminated soil after carrying out geotechnical works in a localized enterprise in the south of São Paulo. The release of the contaminated material for disposal was carried out through monitoring by means of gas meters indicating the qualitative aspects of the samples. The meters assisted in the selection of the most contaminated soil horizons to collect the samples, following the procedures NBR 15492 (2007) for quantitative laboratory analysis of chemical compounds, and the determination of the samples, conditioning and preservation of the samples followed the guidelines described by CETESB . The sustainable proposal for the remediation of contaminated soil was through burning it as an energy fuel for the cement industry and the ashes generated during the process were incorporated into the cement manufacturing blend. With all the procedures carried out on the spot, it was possible to draw an economic and comparative analysis of the conducts and executions adopted with the norms in force in Brazil, promoting guidelines within the works located in urban centers.
