Nametnici na kavezno uzgojenoj ribi u Jadranu

With the rapid development of aquaculture in the Mediterranean, a number of parasitic diseases have emerged in cage-reared fish. In confined rearing conditions, the diseases can induce mortality and economic losses related to suppressed growth. With diversification of aquaculture products and the introduction of new fish species into the rearing system, new parasitic pathogens have found their way into new environments, resulting in adaptation of the parasite, new colonization on resident aquaculture species (primarily sea bass and sea bream), or increased parasite prevalence and abundance on the newly cultivated fish species. The parasitofauna of reared fish is impoverished in terms of species richness and has greater population values than in the wild fish population. While the parasitofauna of fish reared in the Mediterranean is discussed in numerous publications, only occasional findings specifically refer to the Adriatic Sea. Wild fish populations in the Adriatic Sea have been sampled for parasite isolation and identification but an overview of reared fish parasitofauna has never been reported. This was the main goal of this study.Brzim razvojem marikulture na Mediteranu, pojavile su se brojne bolesti uzrokovane nametnicima na kavezno uzgojenoj ribi. U ograničenim uzgojnim uvjetima, bolesti mogu prouzročiti mortalitet i ekonomske gubitke zbog usporenog rasta. Uvođenjem novih proizvoda u marikulturi, te novih ribljih vrsta u uzgojnom sistemu, novi nametnički patogeni su pronašli svoj put u novim okružjima adaptirajući se i kolonizirajući tako novo uzgojene vrste (pretežito lubina i arbuna) ili su povećali rasprostranjenost nametnika na novo uvedenim vrstama u uzgoju. Parazitofauna uzgojene ribe je osiromašena sa stanovišta bogatstva vrsta i ima veće populacijske vrijednosti nego parazitofauna divlje ribe. Iako je parazitofauna uzgojene ribe u Mediteranu istraživana u brojnim publikacijama, tek povremeni nalazi se odnose na Jadransko more. Populacija divlje ribe u Jadanskom moru je bila uzorkovana za izolaciju i identifikaciju nametnika, ali pregled parazitofaune uzgojene ribe do sada nije objavljen. Ovo je bio glavni cilj istraživanja

Decision Support System for Demining Waterways

In the beginning of 2002, Croatian Waters, a state water management system, gave the Faculty of Civil Engineering at the University of Split a project with the main objective of determining the optimal strategy for demining waterways by using contemporary scientific methods and tools

RANKING ENTERPRISES IN TERMS OF COMPETENCES INSIDE REGIONAL PRODUCTION NETWORK

Today\u27s economic crisis has led to bankruptcy of many successful, but usually large-sized enterprises. This brought into question the future of large-sized enterprises. However, the only alternative to largesized enterprises (LEs) is networking of small and medium-sized enterprises (SMEs) into Regional Production Networks (RPNet). RPNet is non-hierarchical organizational form in which every SME is autonomous. Hence, every SME of production network is capable and wiling to be part of special cooperation inside network called Virtual Enterprise (VE). For each new product a new virtual enterprise is formed from different SMEs. The question is: which SMEs will be part of new virtual enterprise? If it is possible to evaluate SME\u27s competences, it is also possible to rank SMEs. Ranking of SMEs according to technical, organizational and human competences is multi-criteria decision analysis (MCDA) problem. So, in this paper PROMETHEE method is selected to perform a ranking of SMEs

VAT rate change and its impact on liquidity

In today\u27s globalized world which is characterized by very quick changes, the need for cash is greater than ever before. The company\u27s liquidity has become one of the most important categories in business. Tax changes that occur in the Republic of Croatia practically from one tax period to another have an impact on the overall business including its liquidity. Therefore, it has become increasingly important for businesses to maintain an adequate level of liquidity and to continuously analyse and monitor it through certain financial ratios. The paper demonstrates a potential impact of the general VAT rate change on liquidity. Companies are divided into two groups. The first group consists of companies that in the years after tax rate changes continue with normal business activity. The second group comprises companies that have been faced with business discontinuity in the years following the change. Possible differences between the liquidity ratios of the companies that have gone bankrupt and companies that have not gone bankrupt after the general VAT rate increase from 22% to 23% are explored. In compliance with the time scope of tax change that occur in one tax accounting period, liquidity is also analysed in the year preceding the year in which the VAT rate was changed

Planning support concept to implementation of sustainable parking development projects in ancient Mediterranean cities

This paper proposes a planning support concept (PSC) to implementation of sustainable parking development projects (SPDP) in ancient Mediterranean cities. It is conceptualized by the logic of decision support systems and a multicriteria analysis approach. The purpose of the concept is to support setting of implementation priorities for subprojects (construction of new and/or improvement of existing parking) within a SPDP. Analysing the existing and a planned state of parking within the city a goal tree is established. Subprojects are defined accordingly. Objectives from the last hierarchy level within the goal tree are used as criteria for assessment of defined subprojects. Representatives of stakeholders provided criteria weights by application of AHP and SAW methods. PROMETHEE II was used for priority ranking and PROMETHEE V ensured a definition of project’s implementation phases. The result of the presented concept is the implementation plan for such projects. The concept is tested on the city of Trogir

Optimization of the selection of competence cells in regional production network

Današnja svjetska gospodarska kriza pokazala je da uspješno poslovanje poduzeća u normalnim ekonomskim uvjetima nije garancija održivosti, tako da je kriza odvela u stečaj mnoga poslovno uspješna poduzeća, a pogotovo velika poduzeća. Ovo je dovelo u pitanje budućnost velikih poduzeća, no u isto vrijeme i otvorilo pitanje postoji li alternativa velikim poduzećima. Alternativa, dakako, postoji u umrežavanju malih i srednjih poduzeća i njihovom optimalnom odabiru u stvaranju novih virtualnih poduzeća. Ovaj se rad bavi baš navedenim problemom odabira kooperanata (kompetencijskih stanica) za određeni novonastali proizvodni proces. Pretpostavlja se da je poduzeća moguće međusobno usporediti i rangirati, što otvara prostor za optimiranje pomoću algoritma Ant Colony Optimization (ACO).The ongoing world economic crisis has shown that being a successful enterprise in normal economic conditions is not a guarantee of sustainability. So the crisis has led to bankruptcy of many successful enterprises, especially large-sized enterprises. This brought into question the future of large-sized enterprises, but at the same time raised the question whether there is an alternative to large-sized enterprises. Of course, there is an alternative in networking of small and medium-sized enterprises and their optimal selection in the creation of new virtual enterprises. This paper deals with the problem of the selection of cooperators for the new production process. It is assumed that enterprises can be mutually compared and ranked, and that makes optimization possible, using Ant Colony Optimization (ACO) algorithm

Project management in mine actions using Multi-Criteria-Analysis-based decision support system

In this paper, a Web-based Decision Support System (Web DSS), that supports humanitarian demining operations and restoration of mine-contaminated areas, is presented. The financial shortage usually triggers a need for priority setting in Project Management in Mine actions. As part of the FP7 Project TIRAMISU, a specialized Web DSS has been developed to achieve a fully transparent priority setting process. It allows stakeholders and donors to actively join the decision making process using a user-friendly and intuitive Web application. The main advantage of this Web DSS is its unique way of managing a mine action project using Multi-Criteria Analysis (MCA), namely the PROMETHEE method, in order to select priorities for demining actions. The developed Web DSS allows decision makers to use several predefined scenarios (different criteria weights) or to develop their own, so it allows project managers to compare different demining possibilities with ease

APPLICATION OF GIS AND MATHEMATICAL MODELING IN MARITIME CRISIS SITUATIONS

This paper aims to propose a decision support system for maritime crisis situation, due to fact that Croatia has decided to implement Directive 2002/59/EC to define places of refuge for ships in need of assistance off their coasts, or to develop techniques for providing assistance to such ships. In order to fulfill this Directive it is necessary to build an effective Decision Support System (DSS) based on GIS and mathematical modeling. The basic module of the proposed system is GIS, for all levels of DSS, that comprise information subsystems about spatial and other data and serves the other modules with data and information. Starting points for analysis are shipping corridors, and 380 potential locations for places of refuge designated in the official navigational pilot book. Multicriteria analysis, with GIS-generated input data, has been used to establish "worthiness" of a place of refuge for each ship category, taking into account kinds of accident. Proposed mathematical models facilitate optimal usage of "available intervention resources"

Hierarchic Approach to Mine Action in Croatia

The Republic of Croatia is one of the 10 most mine-contaminated countries in the world. There are almost 750,000 mines on 1,630 sq km of mine-suspected areas. About 170 sq km are actual minefields, while the rest of the area is contaminated with individual explosive ordnance. Mine-affected areas that have not been used for years, pose a huge economic problem and obstruct infrastructure development, reconstruction, and return of displaced persons to their normal lives. They also pose a significant safety problem. In particular, any activities carried out in mine-contaminated areas significantly threaten human lives and material assets. It is estimated that removing all the mines in the Republic of Croatia would cost approximately $1.473 billion (U.S.) and would require 10 years of intensive work
