Moderating effects between job insecurity and intention to quit in samples of Slovene and Austrian workers
Paul Jiménez, Borut Milfelner, Simona Šarotar Žižek, Anita Dunkl, 2017, izvirni znanstveni članek

Opis: Job insecurity is a serious stressor in the work environment, with negative work-related outcomes. The effects of job insecurity strongly depend on the country’s economic condition. The present study investigated the relationship among job insecurity, job satisfaction, and the intention to quit as well as possible mediating variables (resources/recovery and stress). The samples of 251 Slovene and 219 Austrian workers were analyzed. The data indicated that job insecurity is related to higher stress and intention to quit as well as to lower resources/recovery at the workplace. Stress is an important mediator in the relationship between resources/recovery and job satisfaction as well as intention to quit. These relationships were found in both samples.
Ključne besede: intention to quit, job insecurity, job satisfaction, resources, recovery, stress

APPLYING THE GRAIN-BOUNDARY DIFFUSION PROCESS USING ELECTROPHORETIC DEPOSITION TO SELECTED REGIONS OF A Nd-Fe-B MAGNET
Blaž Goričar, 2014, magistrsko delo

Opis: This Master's thesis research is about the localized coercivity enhancement of Nd-Fe-B magnets, which are used in electric motors. Computer simulations show, that when magnets operate at high temperatures, they experience large demagnetizing fields. However, this happens only on specific parts of the body of the magnet. The demagnetization can be prevented by locally enhancing the coercivity only on these specific parts. The goal of this Master’s thesis was to research the localized coercivity enhancement by creating a magnet, where one half would have different magnetic properties compared to the other half. Commercially available Nd-Fe-B magnets were bought from Shin-Etsu, Japan. The magnetic properties of the magnets were measured on two very different devices – the permeameter and the vibrating sample magnetometer. The demagnetization curves were compared. The coercivity of the magnet was improved with the electrophoretic deposition of dysprosium on the surface. The dysprosium then diffused, at high temperature, from the surface to the inside of the magnet along the grain boundaries. The microstructure of the magnet was analysed on the scanning electron microscope, while the content of the elements was quantitatively analysed with the EDS method. The demagnetization curves of both devices were comparable. The grain-boundary diffusion process of dysprosium with the electrophoretic deposition increased the coercivity of the magnet by 25 %, without any significant loss in remanence. The research on the localized grain-boundary diffusion was first done with measurements on the vibrating sample magnetometer and then confirmed with the Hall probe. We discovered that one part of the magnet could have different magnetic properties compared to the other half. There was a clear border between the two.
Ključne besede: Nd-Fe-B magnet, coercivity, magnetic properties, electrophoretic deposition, grain-boundary diffusion process.

Vizing's conjecture: a survey and recent results
Boštjan Brešar, Paul Dorbec, Wayne Goddard, Bert L. Hartnell, Michael A. Henning, Sandi Klavžar, Douglas F. Rall, 2009

Opis: Vizing's conjecture from 1968 asserts that the domination number of the Cartesian product of two graphs is at least as large as the product of their domination numbers. In this paper we survey the approaches to this central conjecture from domination theory and give some new results along the way. For instance, several new properties of a minimal counterexample to the conjecture are obtained and a lower bound for the domination number is proved for products of claw-free graphs with arbitrary graphs. Open problems, questions and related conjectures are discussed throughout the paper.

Vizing's conjecture: a survey and recent results
Boštjan Brešar, Paul Dorbec, Wayne Goddard, Bert L. Hartnell, Michael A. Henning, Sandi Klavžar, Douglas F. Rall, 2012, pregledni znanstveni članek

Opis: Vizingova domneva iz leta 1968 trdi, da je dominacijsko število kartezičnega produkta dveh grafov vsaj tako veliko, kot je produkt dominacijskih števil faktorjev. V članku naredimo pregled različnih pristopov k tej osrednji domnevi iz teorije grafovske dominacije. Ob tem dokažemo tudi nekaj novih rezultatov. Tako so na primer pokazane nove lastnosti minimalnega protiprimera, dokazana je tudi nova spodnja meja za produkte grafov brez induciranega ▫$K_{1,3}$▫ s poljubnimi grafi. Skozi celoten članek so obravnavani pripadajoči odprti problemi, vprašanja in sorodne domneve.

Some results on total domination in direct products of graphs
Paul Dorbec, Sylvain Gravier, Sandi Klavžar, Simon Špacapan, izvirni znanstveni članek

Opis: Upper and lower bounds on the total domination number of the direct product ofgraphs are given. The bounds involve the ▫$\{2\}$▫-total domination number, the total 2-tuple domination number, and the open packing number of the factors. Using these relationships one exact total domination number is obtained. An infinite family of graphs is constructed showing that the bounds are best possible. The domination number of direct products of graphs is also bounded from below.

How long can one bluff in the domination game?
Boštjan Brešar, Paul Dorbec, Sandi Klavžar, Gašper Košmrlj, 2017, izvirni znanstveni članek

Opis: The domination game is played on an arbitrary graph ▫$G$▫ by two players, Dominator and Staller. The game is called Game 1 when Dominator starts it, and Game 2 otherwise. In this paper bluff graphs are introduced as the graphs in which every vertex is an optimal start vertex in Game 1 as well as in Game 2. It is proved that every minus graph (a graph in which Game 2 finishes faster than Game 1) is a bluff graph. A non-trivial infinite family of minus (and hence bluff) graphs is established. Minus graphs with game domination number equal to 3 are characterized. Double bluff graphs are also introduced and it is proved that Kneser graphs ▫$K(n,2)$▫, za ▫$n \ge 6$▫, are double bluff. The domination game is also studied on generalized Petersen graphs and on Hamming graphs. Several generalized Petersen graphs that are bluff graphs but not vertex-transitive are found. It is proved that Hamming graphs are not double bluff.

Zdravstvena vzgoja bolnika z astmo v referenčni ambulanti
Mihela Grušovnik, 2016, diplomsko delo

Opis: Temeljno izhodišče: Astma je pogosto kronično obolenje. Bolezen vpliva na celotno dihalno pot, če je k astmi priključen tudi alergijski rinitis. Pacient potrebuje zdravstveno vzgojo o astmi, saj mora poznati način in pravilno uporabo zdravil, metode lajšanja simptomatike, izogibanja faktorjem, ki bolezen poslabšujejo, in načine, kako ravnati v primeru astmatičnega napada. Zaradi tega ima medicinska sestra pomembno vlogo pri informiranju in preverjanju znanja pacienta o njegovi bolezni. Od vsakega individuuma pa je odvisno, ali bo navodila upošteval, želel imeti urejeno astmo in s tem kakovostno vsakdanje življenje. Metoda dela: Uporabili smo deskriptivna metodo dela. V raziskavi smo uporabili kvalitativno metodo dela in je bila opravljena na primeru pacientke z urejeno astmo. Izveden je bil intervju po enajstih funkcionalnih vzorcih po Marjory Gordon. Rezultati: V raziskavi je bilo ugotovljeno, da astma vpliva na vsakodnevno življenje pacienta, saj se mora nenehno prilagajati in izogibati dejavnikom, ki poslabšujejo simptomatiko bolezni. Rezultat intervjuja s pacientko z urejeno astmo je pokazal, da se težave po enajstih funkcionalnih vzorcih pojavljajo pri prehrambnem in metaboličnem procesu, izločanju, fizični aktivnosti, zaznavanju samega sebe in obvladovanju stresnih stanj, pri čemer enajst funkcionalnih vzorcev po Marjory Gordon zadostuje za celostno obravnavo pacienta z astmo v referenčni ambulanti. Diskusija in zaključek: Če želi imeti pacient z diagnosticirano astmo kljub bolezni urejeno življenje, mora upoštevati navodila zdravnika in zdravstveno-vzgojno delo medicinske sestre.
Ključne besede: astma, anatomske in patofiziološke spremembe dihal, diagnosticiranje in zdravljenje, vloga medicinske sestre, zdravstvena vzgoja
