Ecological models have often been used in order to answer questions that are in the limelight of recent researches such as the possible effects of climate change. The methodology of tactical models is a very useful tool comparison to those complex models requiring relatively large set of input parameters. In this study, a theoretical strategic model (TEGM ) was adapted to the field data on the basis of a 24-year long monitoring database of phytoplankton in the Danube River at the station of G¨od, Hungary (at 1669 river kilometer – hereafter referred to as “rkm”). The Danubian Phytoplankton Growth Model (DPGM) is able to describe the seasonal dynamics of phytoplankton biomass (mg L−1) based on daily temperature, but takes the availability of light into consideration as well. In order to improve fitting, the 24-year long database was split in two parts in accordance with environmental sustainability. The period of 1979–1990 has a higher level of nutrient excess compared with that of the 1991–2002. The authors assume that, in the above-mentioned periods, phytoplankton responded to temperature in two different ways, thus two submodels were developed, DPGM-sA and DPGMsB. Observed and simulated data correlated quite well. Findings suggest that linear temperature rise brings drastic change to phytoplankton only in case of high nutrient load and it is mostly realized through the increase of yearly total biomass.

A számítógépes munkavégzés elterjedése számos szempontból és módszerrel vizsgálható. A szerző kutatásai során az ember-gép-környezet összhang megteremtésének igényéből kiindulva arra keresi a választ, hogy milyen tényezők befolyásolják a számítógéppel végzett tevékenységek megszervezésének és végrehajtásának hatékonyságát. Tanulmányában a kutatás indítófázisának főbb eredményeiről, a számítógép-használati szokásokról ad áttekintést, ami elengedhetetlen az irodai-adminisztratív jellegű tevékenységekhez kötődő kritikus tényezők feltárásához, továbbá a mérési és fejlesztési feladatok megalapozásához. A szűkebb értelemben vett ergonómiai szempontok mellett a digitális kompetenciák kérdéskörét vonta be a munkába, amit releváns kérdésnek tart a hatékonyság mérése szempontjából, mivel a számítógép megválasztása és a munkahely kialakítása nem értékelhető az emberi tényező alkalmassága és az elvégzendő feladat tartalma nélkül. __________ Office and administrative work, business corres-pondence, private contacts and learning are increasingly supported by computers. Moreover the technical possibilities of correspondence are wider than using a PC. It is accessible on the go by a cell phone. The author analysed the characteristics of the used devices, the working environment, satisfaction factors in connection with computer work and the digital competence by a survey. In his opinion development in an ergonomic approach is important not only to establish the technological novelties but to utilize the present possibilities of hardware and environment. The reason for this is that many people can not (or do not want) to follow the dynamic technological development of computers with buying the newest devices. The study compares the results of home and work characteristic of computer work. This research was carried out as part of the “TAMOP-4.2.1.B-10/2/ KONV-2010-0001” project with support by the European Union, co-financed by the European Social Fund.
