Cilj. Ukazujući na promjene koje su zahvatile izdavaštvo ubrzanim razvojem informacijsko-komunikacijskih tehnologija, cilj rada temelji na analizi razvoja elektroničke knjige (e-knjige) i ...elektroničkog nakladništva (e-nakladništvo) kroz povijesnu i teorijsku perspektivu, čime se omogućuje detaljan uvid u trenutno stanje, s indicijama budućeg razvoja u Republici Hrvatskoj. S obzirom na malo tržište i ograničenu dostupnost izdanja na hrvatskom jeziku, kao i nedovoljnu upoznatost korisnika s prednostima e-knjige, ovim radom željelo se sve navedene aspekte objediniti na jednom mjestu s ciljem sistematizacije dostupne literature. Iz tog razloga, članak je koristan nakladnicima i autorima koji nisu još prepoznali sve mogućnosti koje nudi elektronička knjiga, ili nisu u potpunosti shvatili njenu svrhovitost.
Pristup/metodologija/dizajn. Primjenjujući metodu analize, sinteze i usporedbe, ovim radom se daje detaljna procjena snaga, slabosti, prilika i prijetnji (tzv. SWOT analiza) elektroničkoj knjizi kao proizvodu e-nakladništva u Republici Hrvatskoj. Sistematičnom analizom do sada objavljene znanstvene i stručne literature, detaljno se navode pozitivne i negativne strane elektroničke knjige, diskutiraju se novi trendovi te daje naznaka budućeg razvoja e-knjige s implikacijama na e-izdavaštvo.
Rezultati. Rezultati ''SWOT'' analize pokazuju da elektronička knjiga posjeduje brojne prednosti poput funkcionalnosti i interaktivnosti, a kojima se može pozicionirati kao koristan medij prijenosa informacija i znanja. S druge strane, upravo ovisnost o tehnologiji je njena najveća slabost. Nove prilike leže u novim suradnjama i novim distribucijskim kanalima, no veliku prijetnju pritom predstavlja konkurencija koja na digitalnim kanalima može doći iz cijelog svijeta.
Originalnost/vrijednost. Iz navedenog pregleda dosadašnje objavljene literature može se uočiti kako nije još dan pregled snaga, slabosti, prilika i prijetnji e-knjizi u Republici Hrvatskoj. Stoga, postoji potreba za navedenom sistematizacijom da bi se dobio jasniji pregled stanja tržišta knjiga, te uvid u potencijalne smjerove budućeg razvoja.
Decision making and management are synonyms. Banks are facing a number of business risks and operational risk is prevalent. Risk management is related to making decisions; therefore, it is important ...for the whole organization. The aim of this paper is to develop a decision-making system when choosing the method of operational risk management by using the Analytical Hierarchical Process (AHP). AHP is an efficient process in solving decision-making problems. The final decision depends on the evaluation of a set of alternatives and decision criteria. Therefore, AHP defines the criteria related to operational risk and the alternatives that the bank management can undertake in order to successfully manage operational risk. The main purpose of the process is to find appropriate solutions for defined user factors in the current competitive environment. The results, obtained by the classical numerical method show that External Factors is the dominant criterion, especially during the financial crisis or the Covid pandemic, and that solutions should be sought in international standards along with using the control tools created by banks themselves.
This paper investigates the effect of polymer modifiers (re-dispersible powder, multifunctional additives, methylhydroxyethylcellulose) on the rheological behavior of emulsions, saturated of calcium ...hydrosilicates to simulate a hydrating cement structure. The subjects of the study were modified emulsions which had varied concentrations of each additive and they were examined comparatively to a base emulsion. Tests were performed with a CR-rheometer ("Himpribor-1", Tula, Russia) applying the Searle measuring principle at various shear rates to characterize viscosity properties. The performance of modified mixtures within the operating period was analyzed by using two parameters-effective viscosity (η) and the proportion of structural failure (|m|). The test results showed that the most important factor influencing rheological characteristics is the addition of methylhydroxyethylcellulose additive-the higher additive amount in the emulsion, the higher the viscosity. Furthermore it was noted in the work that adding olefin sulfonate sodium salt causes reduced viscosities as well as lower shear moduli. If ethylhydroxyethylcellulose and ethylene vinyl acetate additives are used in the same mixture together, the rate of structural failure |m| can be relatively similar and low regardless of whether the mixture has large or small viscosity values.
Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) are among the most common infectious diseases in humans. Due to their frequent occurrence in the community and ...nosocomial settings, as well as the development of resistance to the commonly prescribed antimicrobial agents, an enormous financial burden is placed on healthcare systems around the world. Therefore, novel approaches to the prevention and treatment of UTIs are needed. Although UPEC may harbour a plethora of virulence factors, type I fimbriae and P pili are two of the most studied adhesive organelles, since the attachment to host cells in the urinary tract is a crucial step towards infection. Design of receptor analogues that competitively bind to UPEC surface adhesins placed at the top of pili organelles led to the development of anti-adhesive drugs that are increasingly recognized as important and promising alternatives to antibiotic treatment of UTIs.
Doing business in the market today is unthinkable without new and modern technology, which is one of the key resources by which companies achieve a sustainable competitive advantage. Digitalization ...and digital transformation of business includes a number of information and communication technologies (ICT) that are built into business processes and which make it easier for management to do business but also ensure market recognition. Globalization of business affects the expansion and easier access to markets, whereby the management of the company must find new ways and methods of doing business, where the digital transformation of business and new digital and information-communication technologies have an effect on growth and competitive advantage. The ability of an organization to transform its business towards digitalization and application of new digital technologies largely depends on the management of the company and a clear digital strategy as an integral part of the corporate business strategy. In order to investigate the impact of constant and rapid development of digital technologies on the management of the company from the aspect of its acceptance and integration within the company's strategy, a survey was conducted in the territory of the Republic of Croatia and Croatian export companies (micro, small, medium and large) were included in the survey.
Urbanization is a significant challenge that catchments face around the world leading to difficulty in implementing stormwater-related engineering solutions. This study aimed at investigating the ...impact of land use/land cover change on hydraulic parameters of a rapidly urbanizing river basin, a case of the Jangwani basin in Dar es Salaam, Tanzania. In this study, the peak discharges were estimated using the SCS-Curve Number Method under the combination of ArcGIS and HEC HMS for three different years (1998, 2009, and 2018). The 100-year rainfall event recorded in 2011 was used to develop the meteorological model in HEC HMS. The steady flow analysis was accomplished using the HEC-RAS software package. To capture the effect of land use/land cover change as well as avoiding variability, the same rainfall dataset was applied for all the three study years. According to the modelling results in HEC RAS, the parameters such as top flow width, average velocity, hydraulic depth, conveyance, shear, stream power as well as the cumulative volume were observed to be increasing with time.
The application of Newton's law of gravity in explaining international trade proved to be very successful. The popularity of a gravity model for explaining trade flows has been due to the fact that ...the calculations require affordable data for every economy. The basic elements of the panel gravity model are mainly GDP, population and distance. This paper analyses Serbia's trade from 2001 to 2018 based on the experience of neighbouring countries of Croatia and Romania, using STATA software. The trade exchange with more distanced EU members is less realized. The country tends to trade much more with its neighbouring EU members, proving the basic assumption of a gravity model. There are exceptions regarding some parts of the trade with developed EU economies, regardless of their distance. These relations will help us to evaluate the trade pattern and direction of Serbian trade in the EU accession process using a gravity model.
The article presents the results of the conducted study of the possibility and expediency of disperse reinforcement of self-compacting concrete (SCC) in order to improve the physical and technical ...indicators and the analysis of deformative properties of SCC using fiber. For satisfaction of requests from factories-manufacturers of SCC concerning the improvement of physical-mechanical and operational properties of SCC and identification of basic dependences that can be used by them in change of technological regulations for this type of concrete, theoretical and empirical methods of research were used. The results of these studies indicate that the introduction of a certain amount of polypropylene fiber improves the physical-technical and deformation characteristics of the operating SCC compounds, increasing the bending strength and reducing the size of shrinkage deformations. The efficiency of bulk fibre reinforcement with low-modulus polypropylene fibre of SCC mixtures has been experimentally proven in production. From the deduced mathematical dependences practical recommendations on an optimum choice of the sizes and the fibre content in SCC mixtures are proposed to obtain an optimum price-quality ratio, particularly when performing concrete works in summer time.
Entrepreneurship is a key driver of economic growth and a generator of employment opportunities in all modern economies across the world. Small and medium enterprises (SMEs) are the engines of modern ...entrepreneurship. In the Republic of Croatia, SMEs are indispensable to boost employment and economic growth. Numerous economic activities have been slowed down due to the coronavirus pandemic, and some have even been completely halted. In these extraordinary circumstances, not only in the Republic of Croatia but also all over the world, an entrepreneur must be proactive and able to promptly adapt to this new situation. The purpose of this article is to investigate the entrepreneur's position in the Republic of Croatia and to identify key problems entrepreneurs face during the coronavirus pandemic. As indicated by the research results, the coronavirus pandemic has drastically altered business activity conduction and entrepreneurship. For their businesses to survive these new, everyday challenges, many companies are forced to adapt their supply to market demands, introduce business informatization, lower the product and service prices and invest in employee education.
The paper studies the correlation between the FDI and the GDP in the EU15 member states, between 1980 and 2014. The FDI was set as an independent variable, and the GDP as a dependent variable. The ...aim of the paper is to study the correlation between the FDI and the GDP in the states that founded the EU (then the EEC) or joined the EEC/EU up to 1996. The following research hypotheses were set: no. 1, stating that the FDI and the GDP in the EU15 member states show a significant correlation, and research hypothesis no. 2, claiming that EU15 member states of "the EU15 economic periphery" show a higher correlation than the EU15 member states of "the EU15 economic core". The NULL hypothesis, which claims that the FDI and the GDP in EU15 member states do not show a significant correlation, was also set. The Pearson correlation coefficient values verified the research hypotheses for most of the studied states.
