SUCCESS FACTORS OF CHANGE IN KNOWLEDGE MANAGEMENT
The goal of our study is to examine, how the logic of change management implementation and analysing raster of success factors helps to lay the foundation of building up knowledge management system. We led our research first of all along theoretical basis building upon technical literature. We present a generally utilized changing logic extracting those essential elements that get similar importance in the course of building up a learning organizational culture. As a result of our work we established that the utilization of change management logic is indispensable for the successful formation of corporate knowledge management system. Accordingly with the appearance of the demand on continuous learning and putting the individual in the centre both on individual- group- and organizational level simplify work. Comparing the two logics confirms our hypothesis.organization, change management, knowledge, learning organization, knowledge management.
Natalizumab therapy, 2013
Multiple sclerosis (MS) is the most common chronic disease of the central nervous system in young adults. No curative therapy is known. Currently, six drugs are available that can reduce the activity of MS. The first-line drugs can completely reduce the activity of the disease in nearly two-thirds of the patients. In the remainder, who suffer from breakthrough disease, the condition of the patient worsens, and second-line therapies must be used. The second-line drug natalizumab exhibits almost double efficacy of the first-line drugs, but also have less favourable adverse effects. As a severe side-effect for instance, natalizumab carries the risk of the development of progressive multifocal leucoencephalopathy (PML), caused by a polyoma virus, the JC virus. There are three major risk factors for PML: an anti-JCV antibody status, a long duration of natalizumab treatment and prior immunosuppressant therapy. The lowest-risk group (1:14 286) comprises of patients who are anti-JCV antibody-negative, in whom the prior immunosuppressant use and duration of natalizumab therapy do not influence the risk of PML. With no prior immunosuppressant treatment, the incidence of PML increases to 1 in 192 patients after 2 years among those who are anti-JCV antibody-positive. These data may lead the physician to decide to discontinue natalizumab treatment. The half-life of natalizumab is three months; during this time other therapies can not be administered and the patients encounter the rebound effect: as the patients receiving natalizumab therapy displayed a high disease activity before treatment, the rebound effect can lead to relapses. After the termination of natalizumab second-line disease-modifying therapy with fingolimod may be introduce; no PML cases occur in response to fingolimod treatment. In the large majority of patients taking natalizumab who do not develop PML, this drug is highly effective and can prevent the progression of MS. The benefit of therapy and the risk of PML must be considered on an individual basis, with regard to the disease activity, the progression and the MRI activity, before natalizumab therapy is implemented
Mátrix-metalloproteináz-2-gátlás kardioprotektĂv szerepe a miokardiális iszkĂ©mia/reperfĂşziĂłs károsodásban: preklinikai Ă©s klinikai adatok
Az iszkĂ©miás szĂvbetegsĂ©gek, beleĂ©rtve a heveny szĂvizomelhalást, jelenleg vezetik a magyarországi halálozási statisztikákat. Az elmĂşlt közel nĂ©gy Ă©vtizedben intenzĂv kutatás folyt iszkĂ©miaellenes kardioprotektĂv folyamatok Ă©s cĂ©lmolekulák felderĂtĂ©sĂ©re Ă©s gyĂłgyszeres befolyásolására. Ennek ellenĂ©re továbbra sem áll rendelkezĂ©sre az infarktus mĂ©rtĂ©kĂ©t csökkentĹ‘ törzskönyvezett gyĂłgyszer. EzĂ©rt rendkĂvĂĽl fontosnak tartjuk az Ăşj potenciális gyĂłgyszercĂ©lpontok keresĂ©sĂ©t Ă©s az ezirányĂş gyĂłgyszerfejlesztĂ©st. A mátrix-metalloproteinázok (MMP), kĂĽlönösen az MMP-2 szerepe a miokardiális iszkĂ©mia/reperfĂşziĂłs károsodásban több mint 2 Ă©vtizede ismert Ă©s intenzĂven kutatott terĂĽlet. KutatĂłcsoportunk a 2000-es Ă©vek elejĂ©n kapcsolĂłdott be ebbe a tĂ©mába gyĂłgyszerfejlesztĂ©si szándĂ©kkal. Korábban erĹ‘s, magyar kĂ©miai fejlesztĹ‘i háttĂ©r segĂtsĂ©gĂ©vel több ĂgĂ©retes gyĂłgyszermolekula-jelöltet sikerĂĽlt előállĂtanunk, amelyek reprodukálhatĂł mĂłdon kardioprotektĂvnek bizonyultak több preklinikai modellben, azonban a kĂ©mikusi háttĂ©r vizsgálatokbĂłl valĂł kĂ©sĹ‘bbi kiesĂ©se miatt a további kutatások megtorpantak. Jelen tanulmány cĂ©lja, hogy átfogĂł betekintĂ©st nyĂşjtson rĂ©szben a kardioprotektĂv irányĂş MMP-2-gátlás alapkutatási hátterĂ©rĹ‘l, az általunk vĂ©gzett gyĂłgyszerfejlesztĂ©si kĂsĂ©rletek, valamint a nemzetközi irodalomban fellelhetĹ‘ klinikai vizsgálatok eredmĂ©nyeirĹ‘l
Racionalizáló szervezés egy magyar tulajdonban lévő termelő vállalatnál
A tanulmány cĂ©lja, hogy egy gyakorlati pĂ©ldán keresztĂĽl bemutassa a vesztesĂ©gek feltárására használhatĂł egyik mĂłdszer gyakorlati alkalmazását, melynek segĂtsĂ©gĂ©vel a szerzĹ‘k azonosĂtották a vállalatnál zajlĂł termelĹ‘folyamatban fellĂ©pĹ‘ vesztesĂ©gforrásokat, ezek okait, majd javaslatokat tettek a vesztesĂ©gek csökkentĂ©sĂ©re, lehetĹ‘sĂ©gek szerinti kikĂĽszöbölĂ©sĂ©re. Mindezeket a gazdasági racionalitás elvĂ©nek megfelelĹ‘en három lĂ©pĂ©sben vĂ©geztĂ©k el. A vizsgált cĂ©g szĂ©keket Ă©s asztalokat gyárt mind lakossági, mind közĂĽleti piacra. A szĂ©k Ă©s asztalgyártás terĂ©n piacvezetĹ‘nek számĂt Magyarországon
