DETERMINANTE KREDITNOG REJTINGA RAZVIJENIH ZEMALJA I ZEMALJA U RAZVOJU : Diplomski rad
Kreditni rejting neke zemlje je znaÄajan pokazatelj razvijenosti i kao takav ima znaÄajnu ulogu za tu zemlju. Nositelji ekonomske politike nastoje ostvariti Å”to bolji kreditni rejting, a da bi to ostvarili potrebno je utvrditi koje su determinante koje znaÄajno djeluju na kreditni rejting. Determinante koje znaÄajno utjeÄu na kreditni rejting nisu iste za svaku zemlju. U ovom radu najprije se teorijski, a zatim i empirijski utvrÄuje znaÄaj pojedinih determinati za kreditni rejting razvijenih i zemalja u razvoju. Cilj teorijskog dijela rada je utvrÄivanje znaÄaja kreditnih agencija za financijsko tržiÅ”te te analiziranje ranijih istraživanja u cilju boljeg interpretiranja rezultata dobivenih empirijskim istraživanjem. Glavni cilj ovog istraživanja je dokazivanje jesu li determinante, navedene u dvjema hipotezama, kljuÄne za odreÄenu skupinu zemalja. Determinate koje su navedene kao kljuÄne, u empirijskom dijelu rada su se pokazale statistiÄki znaÄajnima za modele u kojima se pojavljuju. Kao najznaÄajnije determinante za kreditni rejting razvijenih zemalja se javljaju: BDP per capita, saldo tekuÄeg raÄuna, javni dug te nezaposlenost. Kod zemalja u razvoju to su: BDP per capita, proraÄunski deficit, inflacija te rast realnog BDP-a. Dakle, nisu se kao kljuÄne pokazale sve determinante koje su na temelju ranijih istraživanja detektirane kao takve. Zbog toga treba biti oprezan prilikom donoÅ”enja odluka, kojima se nastoji poboljÅ”ati kreditni rejting zemlje.Credit rating of some country is a significant indicator of development and has a significant role for each country. Economic policy leaders seek to achieve a better credit rating, and in order to achieve this, it is necessary to determine which determinants are significant for credit rating. Determinants that have a significant impact on credit rating are not the same for each country. In this work, theoretically, and then empirically, is determined the importance of certain determinants for credit rating of developed and developing countries. The aim of the theoretical part is to determine the importance of credit agencies for the financial market and to analyze earlier research in order to better interpret the results obtained by empirical
research. The main purpose of this research is to prove are determinants listed in two hypotheses crucial for a particular group of countries. The determinants that are crucial, in the empirical part of the work, have been statistically significant for the models they appear in. The most important determinants for the credit rating of developed countries are: GDP per capita, current account balance, public debt and unemployment. In developing countries, they are: GDP per capita, budget deficit, inflation and real GDP growth. Thus, all the determinants that were detected as crucial in earlier researches, are not crucial in this research. This is why is important to be careful at making decision, which can improve the credit rating of the country

SCENARIO SIMULATION MODEL OF THE PRODUCTION, TRANSPORTATION AND ASPHALT PAVING
Organizational processes modelling and scenario simulation is proved to be an efficient tool for the quantitative strengthening of the decision making process. In business of production, transportation and paving of great quantities of asphalt mixture, solving problem of projectās fragmented sub-processes has been emphasized by previous researchers as a high priority. Detached process modeling and optimization without taking into account constraints of interrelations among sub-processes cannot offer the optimal or quality solution. Thus, it is necessary to structure a developing and easily adjustable model which will be able to integrate all sub-processes with their interrelations. In this paper authors gave a review of the findings and recommendations of the previous researches. Based on the recommendations, authors structured a developing simulation model for planning and optimization ājust in timeā chain of processes of production, transportation and paving of great quantities of asphalt mixture. Suggested model is based on the algorithm for scenario simulations which is dynamic and adjustable for changes and updates of the input parameters
METODOLOGIJA I ALGORITAM ZA OPTIMIZACIJU LANCA PROCESA TRANSPORTA ASFALTA
In this paper authors suggest and test evolutionary algorithm of multiple criteria solver (MCS) for asphalt supply chain optimization. On the basis of the defined imperfection of the basic mathematical model authors made an algorithm and conducted simulations of transportation problems cases generated from the given realistic input intervals in order to determine the constraints and possibilities for improvement of the original model of the transportation problem of large amounts of asphalt mixture. Results have shown that the suggested model verifies and eliminates the lack of the original model. As well, it is shown in which scenarios of transportation problem and to which extent the suggested methodology contributes to the total transportation costs savings and insurance of the programās optimality.U radu je predložen i testiran evolucijski algoritam za optimizaciju lanca procesa transporta asfaltne mjeÅ”avine na gradiliÅ”ta. IzraÄen je algoritam (rjeÅ”avatelj MCS) na temelju definiranog nedostatka postojeÄeg matematiÄkog modela te provedena simulacija sluÄajeva transportnog problema kako bi se utvrdila ograniÄenja i moguÄnosti za poboljÅ”anje originalnog modela za rjeÅ”avanje transportnog problema velikih koliÄina asfaltne mjeÅ”avine. Rezultati su pokazali da predložen model pridruživanja i iskljuÄivanja potencijalnih izvora potvrÄuje i otklanja nedostatak originalnog modela. Pokazano je i u kojim sluÄajevima transportnog problema i u kojoj mjeri predložena metodologija doprinosi uÅ”tedi i osiguranju optimalnosti ponuÄenog programa
Scenario simulation model for optimized allocation of construction machinery
Metode optimizacije imaju veliku važnost pri sužavanju izbora resursa na konaÄni i pri alokaciji resursa u svim fazama projekata. To se naroÄito odnosi na složena projektna okruženja gdje je potrebno provesti alokaciju resursa (strojeva) na viÅ”e graÄevinskih projekata u njihovim raznim fazama i prioritetima. U radu se predlaže model koji se zasniva na algoritmu viÅ”ekriterijske optimizacije i rangiranja scenarija suboptimalnih programa serijskog viÅ”ekanalnog rada graÄevinskih strojeva pri konaÄnom broju strojeva za izbor, te izluÄivanje presjeka optimalnih programa i/ili scenarija programa u složenom okruženju.Optimization methods for narrowing down the choice of resources, and for their allocation, are highly important in all phases of construction projects. This particularly concerns complex project environments where resources (construction machines) have to be allocated to several construction projects at different phases and with different priorities. The authors propose a model based on the multi-criteria optimisation algorithm and the ranking of scenarios involving sub-optimal programs for serial multi-channel operation of construction machines, with a fixed number of machines for final selection, and with separation of the optimum program and/or program scenario cross-sections in complex environment
UTJECAJ PROMJENA U STRUKTURI PROJEKTNIH TIMOVA NA TIMSKU USPJEÅ NOST
Structuring a project team is highly sensitive task, so numerous methods which address the problem have emerged. One of the most effective methods is structuring teams by the team membersā affinities and talents presented as team roles. In this paper, we applied Belbinās Self-Perception Inventory in order to investigate the following questions: Which are the most engaged team roles? How does the absence of the most engaged team members affect the teamās efficiency? How does this change of the team environment affect the member? Our results show that, even in small project teams, changes in team structure will surely have a negative effect on the teamās organizational culture in a short run, and even more importantly they decrease the teamās overall productivity. Also, the changes had a negative effect at the individual level; teams had trouble integrating new members, and individuals had trouble integrating themselves in new teams.Važnost strukturiranja projektnih timova u graÄevinarstvu danas se Äesto zanemaruje zbog razvoja i afirmacije novih koncepata i metoda informatiÄke tehnologije koji se primjenjuju u projektnom menadžmentu. Strukturiranje projektnog tima izuzetno je zahtjevan zadatak i kao takav treba precizan i dobro organiziran sustav i upravljanje. Postoji nekoliko metoda koje se bave tim problemom. Strukturiranje tima prema afinitetima i talentima njegovih Älanova, koje se naziva timskim ulogama, dobro je poznata i provjereno uÄinkovita metoda. Autori su u istraživanju predstavljenom ovim radom primijenili Belbin metodu timskih uloga kako bi istražili koje su najangažiranije timske uloge, kako izostanak najangažiranijih Älanova utjeÄe na uÄinkovitost tima te kako ta promjena timske okoline utjeÄe na Älanove. Rezultati su pokazali da, Äak i u malim timovima, promjene timske strukture sigurno imaju negativan utjecaj na organizacijsku kulturu tima veÄ u kratkom roku, ali Å”to je joÅ” važnije, dugoroÄno smanjuju cjelokupnu uÄinkovitost tima. Promjene su imale negativan uÄinak i na nivou pojedinca, reflektirajuÄi se u Äinjenici da su se novi Älanovi teÅ”ko integrirali u svoje nove timove, odnosno drugi Älanovi su teÅ”ko prihvaÄali novog
PRIMJENA āEINSTEINOVE ZAGONETKEā PRI RJEÅ AVANJU PROBLEMA ALOKACIJE GRAÄEVINSKIH STROJEVA
āEinsteinās riddleā is a popular example of constraints satisfaction problem. Since its introduction, different forms and variations of the riddle have been presented. Regardless of the variant of the riddle, its solution is considered a tough challenge for humans. Researchers have developed and are still developing mathematical models, as well as computational simulation models for solving it. In this article, the authors have modified a previously published mathematical model and developed a computational spreadsheet model for solving the riddle, which provides a unique solution for the riddle. The model was also tested in a small and medium-scaled form for solving constraint satisfaction problems regarding the allocation of construction machines. The authors have also highlighted the modelās limitations for solving such problems and made suggestions regarding necessary modifications in the model to solve more complex problems in the same domain.āEinsteinova zagonetkaā je prepoznatljiv primjer kombinatornog problema ispunjenja ograniÄenja. Ova zagonetka je imala viÅ”e verzija, no bez obzira na formulaciju, uglavnom se smatra vrlo teÅ”kim zadatkom. Znanstvenici su razvijali i dalje razvijaju matematiÄke modele, a potom i raÄunalne simulacijske modele za rjeÅ”avanje spomenutog problema. Autori su u ovome radu modificirali ranije predstavljeni matematiÄki model, a potom prema njemu izradili raÄunalni model, koristeÄi se proraÄunskim tablicama kako bi rijeÅ”ili zagonetku. Model je ponudio jedinstveno rjeÅ”enje u vrlo kratkom vremenu, a potom je ispitan pri rjeÅ”avanju sliÄnog problema u graÄevinskoj praksi. Istaknuta su ograniÄenja u primjeni modela u obliku kojim je rijeÅ”ena āEinstenova zagonetkaā te koje su modifikacije nužne za aplikaciju pri rjeÅ”avanju kompleksnijih problema u istoj domeni
Formacija intramuralnog tromba u desnom atriju bolesnice sa hiperviskoznim sindromom
Masses in the right atrium (RA) are quite rare, but they pose a diagnostic challenge due to a heterogenous differential diagnosis which includes thrombotic masses, tumor metastases, primary heart tumors such as atrial myxoma, papillary fybroelastoma or rhabdomyosarcoma. Central venous catheter and electrostimulator electrodes particularly raise the risk of thrombus formation.Tvorbe u desnom atriju (DA) su rijetke, no predstavljaju dijagnostiÄki izazov zbog heterogene diferencijalne dijagnoze koja ukljuÄuje trombotske mase, metastaze tumora, primarne tumore srca kao Å”to su miksom atrija, papilarni fibroelastom ili rabdomiosarkom. Centralni venski kateter (CVK) i elektrode elektrostimulatora srca naroÄito
poveÄavaju rizik nastanka tromba
