The aim of this study is to identify the correlations between the use case model, data model and the desired user interface (UI). Since use cases describe the interaction between the users and the system, implemented through the user interface with the aim to change the state of the system, the correlation between these three components should be taken into account at the software requirements phase. In this study, the authors have introduced the meta-model of software requirements developed on the identified correlations. Based on this meta-model, it is possible to create a model of concrete software requirements, which enables not only the design and implementation of the user interface, but also the automation of this process. In order to prove the sustainability of this approach, they have developed a special software tool that performs the transformation of the model to an executable source code. They have considered different ways of user interaction with the system, and consequently, they have recommended the set of most common user interface templates. Thus the flexibility of the user interface is achieved, as the user interface of the same use case could be displayed in several different ways, while still maintaining the desired functionality.

Metode: Studija je dizajnirana kao deskriptivna, analitička, studija preseka, a sprovedena je u dve visoke zdravstvene strukovne škole u Srbiji i Crnoj Gori na uzorku od N=76 studenata. Kao instrumenti istraživanja korišćeni su: Pitsburški indeks kvaliteta spavanja (Pittsburgh Sleep Quality Index -PSQI), za procenu kvaliteta spavanja, Epfortova skala pospanosti (Epworth Sleepiness Scale -ESS), za procenu nivoa dnevne pospanosti, Čalderov upitnik umora (Chalder Fatigue Questionnaire -CFQ), za procenu stepena umora, sociodemografski i upitnik o faktorima životnog stila i ponašanja. Rezultati: Kvalitet spavanja je kod 65,8% studenata ocenjen kao loš, a prisustvo prekomerne dnevne pospanosti i simptoma umora je potvrđen kod (50,0% i 55,3%) studenata. Prosečni ukupni skorovi PSQI, ESS i CFQ bili su značajno različiti u odnosu na pol, rad u smenama i zadovoljstvo trenutnim rasporedom rada. Između kvaliteta spavanja, prekomerne dnevne pospanosti i težine umora utvrđena je jaka pozitivna povezanost. Rezultati ove studije ukazuju na neophodnost uspostavljanja efikasnih obrazovnih strategija koje bi omogućile uspostvaljanje zdravih obrazaca spavanja među studentima sestrinstva i medicinskim sestrama, kao i implementiranje higijene spavanja u programe visokoškolskog obrazovanja na studijama sestrinstva.

Summary:Introduction: The aim of this study was to assess sleep quality, level of daytime sleepiness and fatigue among working nursing students and to determine possible relations among them. Methods: It was a descriptive, analytical cross-sectional study conducted in two Colleges of Health Studies in Serbia and Montenegro on a sample of 76 students. Instruments used in this research included: The Pittsburgh Sleep Quality Index (PSQI) for the assessment of sleep quality, The Epworth Sleepiness Scale (ESS) for the assessment of level of daytime sleepiness, The Chalder Fatigue Questionnaire (CFQ) for the assessment of fatigue rates, the socio-demographic questionnaire and the questionnaire on behavior and lifestyle factors. Results: Sleep quality was poor in 65.8% of students and symptoms of daytime sleepiness and fatigue were confirmed in 50.0% and 55.3% of students. The average values of the total score in the PSQI, ESS and CFQ were significantly different with respect to gender, shift work and satisfaction with the current work schedule. The strong positive co...
Virtual worlds, which should be the subject of further research and improvements, in the field of hospital emergency response training for mass casualty incidents, certainly have a promising future.
