The problem of the safety improvement and pollution preventionin maritime tra11Sp011 has become more and more criticaland urgent to solve. In fact, the number of accidents at seahas increased very quickly over time. Concern is growing aboutpoor qualification on safety and poor management standardsin shipping industry. The ISM Code (Intenzational Safety ManagementCode) aims to provide intemational standards for safemanagement of ship operations and for pollution prevention.The paper, which presents a part of the work done by the Universityof Trieste - ISTIEE within the framework of theMETHAR project, aims to identify the expected supp01t fromthe MaJitime Education and Training (MET) systems to implemmttheISM Code, consequently improving safety and preventingpollution. The paper desCiibes first the 01igin, the objectivesof the ISM Code and the standard requirements on METidentified by the Code. Secondly, it summarises the opinions ofthe operators collected through questionnaires. Finally, it identifiesthe possible enrichment of the MET system in order tobel/.er optimise the implementation of the Code.

The intemational legislation places strict requirements onthe safety of navigation and the marine environment. One ofthe solutions to the problem is to enhance the ship navigationcontrol and maintenance with extensive use of informationtechnology, which has largely contributed to the growth of communicationtechnology. On the basis of an analysis of ship systemsautomation in the past, this paper deals with the developmentsand improvements to be expected ill the near future.Four generations of shipboard automation are presented, includingthe characteristics and requirements that the automationof ship control and monitming systems must fulflll in orderto be classified under a particular generation. Fields of furtherenhancement are considered as these will be decisive in increasingthe efficiency of business operations and ship safety.For the pwpose of supporting the claims above, actual trends inthe development of standards, equipment and systems havebeen analysed as well as their impact Oil the ship owner and thecrew.

The paper analyses the actual problems and procedures instudying ergonomics in transportation. Special emphasis is puton the specific features of the problem and the research developmentin accordance with the characteristics of the singlesub-systems and elements of the transportation system and researchapproaches.According to the structure of the development and actualproblems of the research, the following approaches have beenanalysed: psycho-physiological, systemic and technical, cybernetic,exploitation, and pedagogic, within which also the basictasks of studying ergonomics in transp01tation have been indicated.

Before starting and also during the exploitation of va1ioussystems, it is vety imp011ant to know how the system and itsparts will behave during operation regarding breakdowns, i.e.failures. It is possible to predict the service behaviour of a systemby determining the functions of reliability, as well as frequencyand intensity of failures.The paper considers the theoretical basics of the functionsof reliability, frequency and intensity of failures for the twomain approaches. One includes 6 equal intetvals and the other13 unequal intetvals for the concrete case taken from practice.The reliability of the 'alternator- alternator belt' system installedin the buses, has been analysed, according to the empiricaldata on failures.The empitical data on failures provide empirical functionsof reliability and frequency and intensity of failures, that arepresented in tables and graphically. The first analysis perfO!med by dividing the mean time between failures into 6 equaltime intervals has given the forms of empirical functions of fa ilurefrequency and intensity that approximately cotTespond totypical functions. By dividing the failure phase into 13 unequalintetvals with two failures in each interval, these functions indicateexplicit transitions from early failure inte1val into the randomfailure interval, i.e. into the ageing intetval. Functions thusobtained are more accurate and represent a better solution forthe given case.In order to estimate reliability of these systems with greateraccuracy, a greater number of failures needs to be analysed.

Zagreb Airpor covers an area of 300 ha. The space is almostcompletely covered by vmious ailp011 facilities, buildingsand areas. The new role of the Zagreb Airport, the main airportof the independent Croatia is also the domicile of the air-ea/TierCroatia Airlines. It is also the main air base of the Croatian AirForce.Therefore, the capacities need to be expanded and modernised,especially regarding handling of passengers, luggage,cargo, mail and aircraft.The physical plan of the city of Zagreb includes ai1port developmentat the extended cun-entlocation. The first phase ofthe Master Plan includes the construction of a new passengerterminal and accompanying buildings and areas (tax.iways,aprons, parking lots, access roads ... ) and a long-te1m constructionof the second runway.The paper presents the expected traffic, necessary capacitiesand the physical plan regarding the Zagreb Ailp011 development.The implementation of sophisticated technical and technologicalsolutions is planned in the process of handling thepassengers, luggage, cargo, mail and aircraft.

Numerous inhabitants of the Krapina-Zag01je county fulfiltheir needs (work, education, trade) in the City of Zagreb. Themain passenger streams are related to railway transportationwhich, due to insufficient investments in the infrastructure andtransportation means, shows decrease in the service quality. Amodel is proposed for organising suburban and urban railwaytransp011ation in the Krapina-Zag01je county and the City ofZagreb, which would offer better quality in transportation services,increase economic efficiency of railway transp01tation,and thus eliminate the 1isk of having to close down cerlain railroadsin the county.

The article deals with transporl (and logistic) integration ofSlovenia with EU. Because of its position Slovenia has goodopportunities for transportation activities. Transpmtation (andlogistics) is also of extraordinwy imp01tance for economic developmentand appearance on the European and other markets.
