Uvod: Prisilni ukrepi se v predbolnišničnem okolju pogosto uporabljajo. Namen raziskave je bil raziskati pojavnost in odnos reševalcev do prisilnih ukrepov.
Metode: Vprašalnik je izpolnilo 178 ...reševalcev. Vsi sklopi vprašalnika so dosegli primerno zanesljivost (Cronbach alfa > 0,8). Podatki so bili analizirani z opisno statistiko, t-testom, testom ANOVA in Pearsonovo korelacijo ob upoštevani statistični značilnosti p < 0,05.
Rezultati: S prisilnim ukrepom se je že srečalo 165 (92,7 %) reševalcev. Ženske reševalke se v primerjavi z moškimi reševalci počutijo manj varne (t = 3,243, p = 0,03) in se bolj strinjajo s posredovanjem policije (t = –0,572, p = 0,03). Na terenu se najpogosteje uporablja vezanje s policijskimi lisicami, tj. s t. i. vezicami (x = 3,30, s = 1,15). Agresija, usmerjena proti drugim (x = 4,22, s = 0,86), agresija, usmerjena proti sebi (x = 4,23, s = 0,76), in nemir (x = 3,23, s = 0,98) so najbolj upravičeni razlogi za uporabo prisilnih ukrepov. Reševalci menijo, da potrebujejo več znanja s tega področja (x = 3,90, s = 1,01).
Diskusija in zaključek: Reševalci navajajo podobne vzroke za uporabo prisilnih ukrepov, kot jih v že predhodnih raziskavah navajajo zaposleni v bolnišnicah. Toda mnenje reševalcev o uporabi teh sredstev je negativno, z njihovo uporabo se v večji meri strinjajo samo v primeru pacientov z agresivnim vedenjem. Pri svojem delu se reševalci počutijo ogrožene. Glede uporabe prisilnih ukrepov potrebujejo usposabljanje in izobraževanje.

Infrastructure of a distribution systems is facing major challenges with deregulated power system. Reactive power compensation can reduce energy losses in system, improve voltage profile and release ...feeder capacity. Installation of capacitors in distribution network is ensuring more efficient systems, but also provides economic benefit to utility and users. Vital task for capacitor implementation is to determine the best locations and size of capacitors. Hence, capacitor placement has an important role in distribution system planning. In this paper, using the professional software tool DigSILENT Power Factory, optimal capacitor placement is analysed in real low voltage distribution network. Results and analysis show that by optimal capacitor placement annual losses and adequate size for installed capacitors can be calculated. The capacitor placement problem consists of objective function which is composed of power losses and capacitor installation costs subject to bus voltage constraints. Optimization placement calculation is compared to installation of four capacitors in given case study distribution grid. Simulation results show that with appropriate software techniques optimal capacitor placement can be achieved in distribution grid.
