Abstruct-The instability of PMOS dosimetric transistors inThe dosimetric PMOS transistors, also called RADFET's, the form of threshold voltage drift could be an important source of errors in low dose measurements. The source of the drift is, according to the recent nomenclature, switching states concerned with near-interfacial oxide traps (border traps), and we have investigated them for 10 different types of specially prepared PMOS transistors. It has been found that the density of these states depends on the received dose, the bias during irradiation, the temperature, and the thickness of the gate oxide and its hydrogen content. A tunneling model that successfully describes the threshold voltage drift and explains these experimental results is presented. The possible physical picture of border traps and two specific structural models of defects in the Si02 which could be concerned with these experimental results are also discussed.

MODELLING A BUSINESS INTELLIGENCE SYSTEM FOR SCHOOL MANAGEMENT ON LOCAL GOVERNMENT LEVEL Miroslav Huđek, Zoran Savić, Dragan RadovićOriginal scientific paper This paper presents one approach to logical modelling of business intelligence system which should help school management at local level. The use of automated tools for decision makers becomes essential due to the exponential increase of data from several and dispersed sources. As the basis for the creation of a model, Balanced Scorecard method is used, whose dimensions are slightly modified to be suitable for the needs of school management. Created is a data warehouse with defined fact tables and dimension tables, and proposed is a technical solution, adequate to the needs and size of local government. For the application of the model, any founder (local or regional administration) should enter master data, realized values and the scope of activities for its school system, and as a result, through the OLAP cubes, it is possible to analyse main indicators in financing, efficiency and excellence.

Uporaba automatiziranih alata za donošenje odluka postaje bitno zbog eksponencijalnog porasta podataka iz nekoliko i raspršenih izvora. Kao osnova za izradu modela koristi se Balanced Scorecard metoda, čije dimenzije su neznatno modificirane da budu pogodne za potrebe upravljanja školom. Stvoreno je skladište podataka s definiranim činjeničnim tablicama i tablicama dimenzija te je predloženo tehničko rješenje, odgovarajuće za potrebe i veličinu lokalne samouprave. Za primjenu modela, svaki osnivač (lokalna ili regionalna uprava) treba unijeti matične podatke, ostvarene vrijednosti i opseg aktivnosti za svoj školski sustav, a kao rezultat toga, kroz OLAP kocke, moguće je analizirati glavne indikatore u financiranju, učinkovitosti i izvrsnosti.
