Credit Institutions in the Republic of Croatia in the Period From 1991 to 2020

It can be said that there is a day in the entire world when a company is not established or ceases its activity. Among these companies, credit institutions also have their place. The requirements that must be met when establishing banks and other credit institutions are as a rule, more rigorous than when establishing other business entities. Therefore, credit institutions are established less frequently. It can also be noted that they disappear from economic life less frequently. The emergence, and especially the disappearance of a credit institution does not go unnoticed. The same is true for other companies, unless they belong to a group of large and globally known companies. The aim of this paper is to analyse the trends in the establishment and failure of credit institutions in the Republic of Croatia in the period from 1991 to 2020. The research was conducted by studying domestic and foreign scientific and other relevant literature

Učinci razine zaslanjenosti vode za navodnjavanje na produktivnost boba (Vicia faba L.)

In Mediterranean region where seawater intrudes porous karst matrix and salinizes soil and water resources, water used for the irrigation of crops is frequently of inadequate quality. Measuring the productivity of horticultural crops under saline conditions helps to determine whether and when to irrigate crops if water is saline, thus balance between crop water and salt stress. A greenhouse pot experiment was set to study the effects of saline irrigation water on faba bean (Vicia faba L.) biomass and yield parameters. NaCl salinity was applied in a nutrient solution as follows: NaCl0 as control (nutrient solution without added NaCl), NaCl50 (control + 50 mM NaCl), and NaCl100 (control + 100 mM NaCl). Five weeks after salinity treatment started, plant height (cm), number of lateral branches per plant, number of pods and seeds per plant, shoot weight (g), pod weight (g) and seed weight (g) were determined. Compared to control, increased irrigation water salinity statistically significantly decreased measured parameters (P<0.01), except for number of branches and pods. Faba bean productivity decreased proportionally to the irrigation water salinity level, suggesting that optimal saline agriculture management strategy can be to allow for the acceptable yield loss in order to avoid plant water stress.Na području Mediterana, gdje dolazi do prodora morske vode kroz porozni krški materijal i zaslanjivanja tala i vodnih resursa, voda koja se koristi za navodnjavanje usjeva često nije odgovarajuće kakvoće. Mjerenje produktivnosti hortikulturnih usjeva u zaslanjenim uvjetima pomaže odrediti može li se navodnjavati zaslanjenom vodom i kada, kako bi se pronašla ravnoteža između vodnog stresa usjeva i stresa soli. Postavljen je pokus u loncima u plasteniku kako bi se istražili učinci zaslanjene vode za navodnjavanje na biomasu i parametre prinosa boba (Vicia faba L.). NaCl sol je primijenjena u hranjivoj otopini kako slijedi: NaCl0 kao kontrola (hranjiva otopina bez dodanog NaCl), NaCl50 (kontrola + 50 mM NaCl), i NaCl100 (kontrola + 100 mM NaCl). Pet tjedana nakon početka tretmana zaslanjenom vodom, izmjerena je visina biljaka (cm), određen broj bočnih izdanaka, mahuna i sjemenki po biljci, masa nadzemnog dijela biljke (g), masa mahune (g) i masa sjemena (g). U usporedbi s kontrolom, povećana zaslanjenost vode za navodnjavanje statistički je značajno smanjila mjerene parametre (P<0.01), osim broja izdanaka i mahuna. Produktivnost boba smanjila se proporcionalno razini zaslanjenosti vode za navodnjavanje, sugerirajući da optimalna strategija poljoprivrednog gospodarenja u zaslanjenim uvjetima može biti dozvoljavanje prihvatljivog gubitka prinosa kako bi se izbjegao vodni stres usjeva

Јапанска Soft Power архитектура: (не)намерно и неочекивано у политици културне размене

States’ cultural policies for international relations take various forms, both intangible and tangible. This paper will focus on the latter, namely, exported architectural manifestation utilized as cultural negotiation tools. In this research, exported architecture is considered to be any built (realized) spatial manifestations, non-native to the county in which it is placed. Subsequently, architecture is viewed and examined as a cultural resource, having the power to influence bilateral relations presenting a new term, ‘soft power architecture’ as conceived, exported, and state-controlled spatial manifestation, with a clear set of goals inscribed within cultural relations policies. The notion of architecture-as-a-negotiating-instrument between various actors is introduced, borrowing from Joseph S. Nye’s definition of the term “soft power” postulated as, in the most basic terms, as the ability to attract, with attraction often leading to acquiescence.These typologies have a profound impact and yet the policy makers remain unaware of the importance of architectural manifestations as cultural resources. Requirements of the re-conceptualization of the state’s policies regarding the planning, implementation and management processes for diplomatic-consular outpost will be discussed. Lastly, the case study of the new Japanese embassy in Belgrade, Serbia, will be examined, noting particularities of its processes, arguing an unintentional paradigmatic shift, providing a theoretical and methodological framework for future research.Међународни односи и пратеће стратегије културне размене могу попримати различите облике, како нематеријалне, тако и опипљиве. Овај рад ће се фокусирати на другу категорију, наиме, извезене архитектонске манифестације које се могу користити као оруђе у политици културне размене. У овом истраживању, за извезену архитектуру сматра се било која изграђена (реализована) просторна манифестација, која потекла из окружења у којем је смештена. Архитектура ће бити посматрана и испитивана као културни ресурс, који има моћ утицаја на билатералне односе, представљајући нови термин, „Soft Power архитектура“ који подразумева пројектовану, извезену и државно-контролисану просторну манифестацију, са јасним циљевима који одражавају тежње политике културне размене. Уводи се и појам архитектуре као инструмента преговарања између различитих актера, интерпретирајући дефиницију појма „soft power“ Џозефа С. Наја, која је дата, у најосновнијим цртама, као способности привлачења, са привлачношћу која често води ка прихватању ставова друге стране. Ове типологије могу имати снажан утицај по више основа, првенствено на просторну интеракцију и националну репутацију, међутим, креатори политике и стратегија остају несвесни важности раније поменутих архитектонских манифестација као културних ресурса. Чланак ће поставити теоретске оквире неопходности ре-концептуализације државних политика у погледу процеса планирања, спровођења и управљања дипломатско-конзуларним испоставама. Такође, проучавањем студије случаја нове јапанске амбасаде у Београду, примећује се специфичност њених управљачких процеса као и новонасталих просторних последица, стварајући парадигматични помак, описујући теоријски и методолошки оквир за будућа истраживања

Agricultural Management Strategies for Countering Drought Conditions in Eastern Croatia

The occurrence of drought periods which last for several months is becoming increasingly frequent, even in regions which have not encountered them before. Agricultural production is very sensitive to drought, and in areas where such conditions were rather unexpected, it is also unprepared for limited water management. As an example, in the area of the Biđ-Bosut field located in eastern Croatia, a significant change in the agricultural soil water regime is noticed during a long-term study (2003–2018). From 2003 to 2018, the groundwater level at 4 m below the soil surface showed a decreasing trend of 6–10 cm annually, while this negative trend was even more prominent from 2014 to 2018 (18–71 cm annually). Furthermore, water level in a groundwater aquifer at 15 m below the soil surface showed a decreasing trend of 26–77 cm during 2015–2018. In accordance with the obtained results, this study proposes certain agro-hydrotechnical strategies which can be used in agricultural production to alleviate the effects of drought period. Although these management strategies are primarily described on an eastern continental Croatia example, they can also be applied in all agricultural areas with similar agroecological conditions
