Nežymaus ir vidutinio intelekto sutrikimo 5 -8 klasių mokinių adaptacija dailės ugdymo procese / Adaptation of students with slight and medium mental deficiency in educational process of art in 5 - 8 forms

Purauskaitė, Jurgita 16 August 2007 (has links)
Nežymiai ir vidutiniškai sutrikusio intelekto mokiniai turi pažinimo ir bendravimo sunkumų, jie yra daug jautresni nei jų bendraamžiai, jaučia nuolatinę kaltę, nesėkmės kompleksą, nepasitiki patys savimi, tai apsunkina jų integraciją į visuomenę. Meninėje veikloje neįgalieji mokiniai suvokia, kad jų piešiniai skiriasi nuo bendraklasių darbų ir tai sukelia jiems nepilnavertiškumo jausmą, silpnina socialinės adaptacijos galimybes. Šio tyrimo tikslas ištirti nežymaus ir vidutinio intelekto sutrikimų turinčių paauglių adaptacijos galimybes dailės pamokų metu. Uždaviniai: išanalizuoti literatūrą, susijusia su adaptacinėmis mokinių problemomis, paauglių kūryba, kūrybiniais sugebėjimais bei išgyvenimais; išsiaiškinti pagrindinius nežymaus ir vidutinio intelekto sutrikimų turinčių paauglių psichologinius bendravimo ypatumus; ištirti dailinio ugdymo priemonių poveikį nežymaus ir vidutinio sutrikusio intelekto paauglių adaptacijai; išryškinti dailės mokytojo vaidmenį modeliuojant socialinę sutrikusio intelekto paauglių adaptaciją. Hipotezė: sutrikusio intelekto paauglių savarankiško bendravimo gebėjimai komunikuoti dailės kalba galėtų išplėsti jų bendravimo ir bendradarbiavimo galimybes su bendraamžiais, intensyviau plėtoti saviraišką, optimizuoti jų socializacijos procesą, ugdyti pasitikėjimą bei pasitenkinimą savimi. Tyrimo metodai: literatūros analizė, atvejo analizė, dailės užduočių parinkimas ir stebėjimas, piešinių analizė...

Smulkaus ir vidutinio verslo įmonių kreditavimas / The crediting of small and medium – sized enterprises

Stanaitienė, Indra 08 September 2009 (has links)
Tinkamai atliekamos bankų kreditavimo operacijos yra labai svarbios, nes jos padeda nukreipti, paprastai limituotus, šalies piniginius išteklius į dinamiškiausias ir perspektyviausias verslo sritis. t.y. vienas pagrindinių gerai veikiančios rinkos ekonomikos dėsnių. O smulkus ir vidutinis verslas yra ekonomikos varomoji jėga ir socialinio valstybės stabilumo garantas. Šio verslo reikšmės didėjimas tapo akivaizdžiu viso civilizuoto pasaulio esminiu bruožu. Teisinga valstybės politika šioje srityje yra labai svarbus kiekvienos valstybės vidaus politokos uždavinys. Analitikai taip pat sutaria, kad smulkaus ir vidutinio verslo plėtra yra vienas iš prioritetinių Europos Sąjungos ir Lietuvos politikos tikslų. Pirmiausia SVV įmonės yra nuolatinio užimtumo pagrindas – smulkusis verslas tai svarbi priemonė, kovojanti su struktūriniu nedarbu. Antra, didesnis įmonių skaičius duoda postūmį ekonominiam augimui, paskatintam intensyvesnės konkurencijos.SVV įmonės greičiau pajunta rinkos paklausos ir pasiūlos pokyčius, prisitaiko prie jų, užimdamos konkrečias rinkos nišas. Praktinėje dalyje pateikiami tyrimo rezultatai gauti anketinės apklausos būdu iš smulkių ir vidutinių įmonių atstovų. Gauti rezultatai yra interpretuojami bei vertinami, darbo gale pateikiamos tyrimo išvados ir pasiūlymai. / The object of this paper is the crediting possibilities of the small and middle – size lithuanian enterprises.The small and middle business of Lithuania is the garanty of the economics stability and growth.. A risk element always exists in granting loans, so that’s why banks’ must organize rational and will – considered crediting process. Owning to the banks, vacant monetary capital is directed to the most dynamic and perspective business areas, in other words, is converted from idle to functionating capital. The main results of the research are: o the main users of the loans are trade, communication and transport companies; o the main credit market player is Vilnius bank, that takes 48% of the loan market. o the most popular crediting product is big loans ( over 50 000 lt.) with long term period (over 3 year).

An Exploratory Investigation into Chemical Management Practices: A Case Study of Small and Medium-sized Enterprises within Nova Scotia

Thomas, Victoria 12 September 2012 (has links)
Chemical pollution has become an environmental and human health concern. Small and medium-sized enterprises are becoming the focus of environmental researchers, as they have been found to collectively contribute a significant amount of the pollution due to improperly managed chemicals. This case study of Nova Scotia small and medium-sized enterprises aimed to collect baseline information regarding environmental and chemical management including what positive practices were in place, what areas required more assistance, what information is being requested and who should be the focus of information programs. Results indicated that there is significant room for improvement in both the environmental and chemical management practices of small and medium-sized enterprises, even though participants indicated they were employing responsible practices. Participants were however, able to provide multiple suggestions regarding information they require in order to improve their business operations and environmental performance, thereby indicating they are aware improvements are needed.

Improving Nitrogen Use Efficiency of Potted Chrysanthemums Grown in a Subirrigation System

MacDonald, William N. 14 February 2013 (has links)
This thesis tested the hypothesis that nitrogen use efficiency of subirrigated potted chrysanthemum (Chrysanthemum morifolium Ramat.) can be improved by managing the NO3- status of the plant. Replacement of NO3- with water one week prior to flower development was the most effective method of reducing tissue NO3- content and improving the nitrogen usage index, as compared to various combinations of NO3- and Cl-. Shoot or flower dry mass and N content were unaffected and the medium electrical conductivity was reduced. Supplying N in the NH4+ form in combination with NO3- did not affect nitrogen use indices. Reducing N supply improved various indices of nitrogen use efficiency, with a slight loss of quality. Elimination of NO3- prior to flower development and reduction in N supplied are effective strategies for improving nitrogen use efficiency in subirrigated potted chrysanthemums without sacrificing quality. / Cecil Delworth Foundation

Performance study on a dual prohibition Multiple Access protocol in mobile Ad Hoc and Wireless Mesh networks

Wu, Qian 03 January 2008 (has links)
Wireless networks are less reliable than wired networks because channels are “exposed” to the surrounding environment that is susceptible to interference and noise. To minimize losses of data due to collisions, wireless networks need a mechanism to regulate the access on the transmission medium. Medium Access Control (MAC) protocols control access to the shared communication medium so that it can be used efficiently. In this thesis, we first describe the collision-controlled Dual Prohibition Multiple Access (DPMA) protocol [45]. The main mechanisms implemented in DPMA, such as binary dual prohibition, power control, interference control, and support for differentiated services (DiffServ), are presented in detail. We conducted a thorough simulation study on DPMA protocol from several aspects. First, we conduct simulations to observe the effects of binary competition number (BCN), unit slot length and safe margin on the performance of DPMA. Secondly, the DiffServ capability of DPMA is demonstrated through simulation results. Finally, we compare the DPMA protocol with the CSMA/CA protocol and find that DPMA with optimal configuration has better performance than CSMA/CA under both low and high network density. / Thesis (Master, Electrical & Computer Engineering) -- Queen's University, 2007-09-28 16:25:02.515

Translating Early Outgrowth Cell Therapy into a Clinically Relevant Approach for Long Term Renoprotection

Kepecs, David 29 November 2013 (has links)
Current therapy for chronic kidney disease (CKD) is limited; however, recent studies have shown that a subpopulation of cells derived from the bone marrow, known as early outgrowth cells (EOCs), are able to attenuate kidney injury. Here we examined the efficacy of a modular tissue engineering system whereby the EOCs might be easily removed in the event of malignant change. While modular therapy mimicked the effects seen with standard EOC therapy, the modules degraded allowing the encapsulated EOCs to enter systemic circulation. Given the presumed egress of EOCs, we explored an alternative strategy for kidney protection. Here we investigated the long-term effectiveness of administering the conditioned medium (EOC-CM) that contains the factors the EOCs secrete, rather than the cells themselves. In these studies, repeated administration of EOC-CM attenuated the structural and functional manifestations of kidney injury suggesting that this approach may provide an effective and feasible, cell-free approach for CKD.
