Tourism development in the Crikvenica riviera

U radu se analizira razvoj turističkih aktivnosti i djelatnosti u crikveničkom području te njihov utjecaj na transformaciju i raspodjelu prostora. Analiza je podijeljena na dva razvojna ciklusa koja su međusobno odijeljena ratnim razdobljem. Ključna razlika između dva ciklusa nije samo obnova i ponovno uključivanje u turizam uzrokovano ratom, već i promjena u turističkoj potražnji koja je označila potrebu turizma da se prilagodi novim uvjetima temeljenih na razvoju novih oblika turizma. Iz tog razloga, drugo promatrano razdoblje prolazi kroz strukturalne promjene koje se razlikuju od prvog promatranog razdoblja. Zatim, rad se usredotočuje na analizu budućih razvojnih trendova temeljenih na spoznajama turističkih procesa, odnosa, struktura i učinaka iz recentnih razdoblja.This paper analyses the development of tourism activities in the Crikvenica area and their impact on spatial tranformation and distribution. The analysis is divided in two cycles of development that are separeted by the period od war. Key difference between two cycles is, not only the new beginning and fresh start of tourism development caused by war, but also the shift that was made inside of a tourist demand. It marked a need of tourism areas to adapt to new situation based on development of new tourism forms. For that reason, second observed cycle of development goes through structural changes that differs from the first cycle. After that, the paper focuses on the analyses of future trends of tourism development based on the comprehension of tourism processes, relations, structures and impacts in the recent period

Is Neuro-Symbolic AI Meeting its Promise in Natural Language Processing? A Structured Review

Advocates for Neuro-Symbolic Artificial Intelligence (NeSy) assert that combining deep learning with symbolic reasoning will lead to stronger AI than either paradigm on its own. As successful as deep learning has been, it is generally accepted that even our best deep learning systems are not very good at abstract reasoning. And since reasoning is inextricably linked to language, it makes intuitive sense that Natural Language Processing (NLP), would be a particularly well-suited candidate for NeSy. We conduct a structured review of studies implementing NeSy for NLP, with the aim of answering the question of whether NeSy is indeed meeting its promises: reasoning, out-of-distribution generalization, interpretability, learning and reasoning from small data, and transferability to new domains. We examine the impact of knowledge representation, such as rules and semantic networks, language structure and relational structure, and whether implicit or explicit reasoning contributes to higher promise scores. We find that systems where logic is compiled into the neural network lead to the most NeSy goals being satisfied, while other factors such as knowledge representation, or type of neural architecture do not exhibit a clear correlation with goals being met. We find many discrepancies in how reasoning is defined, specifically in relation to human level reasoning, which impact decisions about model architectures and drive conclusions which are not always consistent across studies. Hence we advocate for a more methodical approach to the application of theories of human reasoning as well as the development of appropriate benchmarks, which we hope can lead to a better understanding of progress in the field. We make our data and code available on github for further analysis.Comment: Surve

Use of Modern methods for Evaluation of Motor Performance

The development of instruments and the use of the same is expanding from year to year. The paper aims to determine the usefulness of Myotesta (MT), Optojump (OJ), Globe Ergo System (GES) as modern methods for assessing motor performance. The research included nine original scientific papers. All works satisfied the problem and could answer the set goal. The selection of works from 2009. to 2014. was taken as a method. There are specific differences when comparing the results for each of the instruments. Myotest has stood out as the smallest instrument and is easily portable and therefore effective to use. The assessment of explosive power is easy to perform, and the results it gives are reliable

Microwave Assisted Esterification of Aryl/Alkyl Acids Catalyzed by N-Fluorobenzenesulfonimide

The susceptibility of the carbonyl group towards nucleophilic attack affords the construction of various organic compounds. Thus, investigations of carbonyl activation applying greener methodologies are highly important. In the present work, among the investigated N-halo compounds, N-fluorobenzenesulfonimide (NFSi) has been found as an efficient and selective catalyst in the reaction of direct esterification of aryl and alkyl carboxylic acids supported by microwave (MW) irradiation. The comprehensive esterification of different benzoic acids and mono-, di-and tri-carboxy alkyl derivatives was performed, whereby significant reaction time reductions were achieved. The presented method used NFSi as an easily manipulatable, non-metal, water-and air-tolerant catalyst, allowing simple synthetic and isolation procedures and energy saving, compared to conventional methodologies. Importantly, in contrast to esterification under thermal conditions, where N-halo compounds behave as pre-catalysts, in the MW-supported protocol, a distinct reaction mechanism has been proposed that assumes NFSi as a sustainable catalyst. Moreover, a scale-up of the industrially important derivative was performed

Antiproliferative and antimigratory effects of 3-(4-substituted benzyl)-5-isopropyl-5-phenylhydantoin derivatives in human breast cancer cells

In this study, a series of synthesized 3-(4-substituted benzyl)-5-isopropyl-5-phenylhydantoin derivatives as a potential antiproliferative and antimigratory agents were investigated. The possible antitumor mechanisms of investigated hydantoin derivatives were examined on human breast cancer cell line MDA-MB-231. The cells were treated with different concentrations of compounds (from 0.01 mu M to 100 mu M) during 24 h and 72 h. The proliferation index, nitric oxide production, apoptosis rate, and migration capacity were measured. The cell invasion potential was examined by measuring the level of MMP-9 and COX-2 gene expression. All tested compounds expressed antiproliferative activity and induced dose- and time-dependent increase in the level of nitrites. The investigated molecules significantly decreased cell survival rate, migration capacity and the expression levels of genes included in the process of tumor invasion. Obtained data suggest that the tested hydantoin derivatives express considerable antitumor activity by reducing cell division rate, elevating apoptosis level, and inhibiting the motility and invasiveness of breast cancer cells. The results obtained in this study indicate that investigated compounds express potential as a novel chemotherapeutic agents against breast cancer growth and progression. (C) 2020 The Author(s).

On the universal parabolic constant

U članku se razmatra univerzalna parabolička konstanta kao analogon broja $pi$ u slučaju kružnice. Pritom se zasebno navode svi bitniji pojmovi i rezultati iz algebarske teorije brojeva, elementarne matematike i diferencijalno-integralnoga računa nužni za potpunost i ispravnost cjelokupnoga razmatranja. Promatra se omjer duljine luka parabole određenog pravcem koji prolazi žarištem parabole usporedno s njezinom ravnalicom i udaljenosti žarišta parabole od njezine ravnalice. Pokazuje se da taj omjer ne ovisi o izboru parabole, pa se time dokazuje dobra definiranost pojma univerzalne paraboličke konstante. Uz primjenu Lindemannova rezultata o transcedentnosti broja $pi$ zaključuje se da je ta konstanta transcendentan, dakle i iracionalan broj. Ukratko se razmatra i svojstvo sličnosti krivulja, pa se utvrđuje da ono vrijedi za sve kružnice i za sve parabole, a ne vrijedi za elipse i hiperbole. Kao primjeri primjene promatrane konstante, izračunavaju se oplošja rotacijskih tijela dobivenih vrtnjom grafova dviju elementarnih funkcija oko osi apscisa, te prosjeci udaljenosti svih točaka jediničnoga kvadrata od središta toga kvadrata, odnosno od proizvoljnoga, ali fiksiranoga vrha kvadrata. Za probleme izračuna prosjeka navodi se i njihova formulacija u terminima teorije vjerojatnosti.In this article the universal parabolic constant is defined as the analog of the number $pi$ in relation to the circle. For this purpose, all relevant terms and results in algebraic number theory, elementary mathematics and calculus are stated, necessary to consider the subject completely and adequately. It is shown that the ratio of arc length of the parabolic segment, determined by the line through the focus parallel to the directrix, and the distance between the focus and the directrix, does not depend on the particular parabola, justifying the constant\u27s definition. Applying the Lindemann\u27s result that the number $pi$ is trancedental, the proof is given that the universal parabolic constant is a transcendental and hence an irrational number. Furthermore, the property of similarity of curves is analyzed, establishing that all circles and parabolas satisfy this property, while ellipses and hyperbolas do not. Two sets of examples of the application of the parabolic constant are given. One is calculating the surface area of certain rotational solid objects, created by rotating graphs of elementary functions around the $x$-axis. The other involves analyzing problems of determining the average distance of points in a unit square to the center of the square, or to any randomly chosen but fixed vertex of the square. As to the latter, their probability theory counterparts are stated

Kvantitativne metode odlučivanja - problem složene razdiobe ulaganja

U ovom ćemo članku razmatrati odabrane primjene problema složene razdiobe ulaganja i način njihovih rješavanja primjenom metoda i tehnika dinamičkoga programiranja. Problem složene razdiobe ulaganja predstavlja svojevrsno poopćenje problema jednostavne razdiobe ulaganja. Temeljna razlika u odnosu na problem jednostavne razdiobe ulaganja jest što je svakoj pojedinoj kategoriji (npr. gospodarskoj grani, tvrtki, odjelu unutar iste tvrtke i sl.) pridružen tzv. težinski koeficijent. To konkretno znači da pri razdiobi ukupnoga novčanog iznosa na određene kategorije te kategorije nisu međusobno ravnopravne, nego rangirane prema nekom kriteriju. Pritom ne nužno postoji jedinstvena najbolje rangirana kategorija i/ili jedinstvena najslabije rangirana kategorija. Točnije, pretpostavljamo da postoje barem dvije kategorije s različitim rangovima jer se u suprotnom problem složene razdiobe ulaganja svodi na problem jednostavne razdiobe ulaganja. (Ekvivalentno, možemo reći da su u problemu jednostavne razdiobe ulaganja težinski koeficijenti unimorfno raspodijeljeni, dok su u problemu složene razdiobe ulaganja prilagođeni.

On the devil\u27s curve

U članku se najprije opisuje veza krivulje s igrom diabolo prema kojoj je krivulja dobila i svoje originalno ime. Ukratko se izlaže povijest proučavanja krivulje, kao i osnovne definicije i pojmovi iz algebarske geometrije koji se koriste u daljnjem razmatranju. Potom se navodi definicija te razmatraju osnovna svojstva i osnovni oblici zapisa jednadžbe vražje krivulje, pri čemu se posebno izvodi parametarski oblik dotične jednadžbe. Kao tipičan primjer, zasebno se razmatra tzv. elektromotorna krivulja i njezina svojstva. Na kraju se daje jedna od mogućih elementarnih konstrukcija vražje krivulje pomoću jednakostrane hiperbole.In this article, we firstly describe the connection between the devil\u27s curve and the game of "diabolo" the curve is named after. We shortly describe the history of studying the curve, as well as basic definitions and terms of algebraic geometry used in the article. Then we give the definition, basic properties and basic forms of the equation of the curve, whereby we especially derive the parametric equation of the curve. As a typical example of the devil\u27s curve, we consider the electric motor curve and its properties. Finally, we consider one of the possible constructions of the devil\u27s curve using the equilateral hyperbola
