V pričujočem prispevku skušam strniti nekaj misli o specifičnih elementih erotičnega imaginarija epizode o Moreju in Halkomedeji v Nonosovem Epu o Dionizu, to sta motiv kače, varuhinje devištva, in ...motiv nekrofilije. Najprej podajam shematičen prikaz zgradbe obeh motivov z ozirom na proleptično Nonosovo poetiko. Pri motivu kače gre predpostaviti tročleno zgradbo (prefiguracija v 15. knjigi, prerokba v 33. knjigi in osrednji prizor v 35. knjigi), pri nekrofiliji pa dvočleno (prefiguracija in osrednji prizor v 35. knjigi). Že v poprejšnjih raziskavah izrečena predpostavka, da gre tudi pri prizoru nekrofilije v resnici za prefiguracijo (Moreja) ocenjujem za smiselno zaradi podobnosti likov (anonimni vojščak, anonimnost kot značilnost »tipa«) in v kompozicijskem oziru. V pragmatičnem oziru je, če želimo ta prizor razumeti kot prefiguracijo, nujno predpostaviti bralčevo poznavanje epizode o Kalimahu in Druzijani iz Janezovih del, ki, kot je bilo ugotovljeno že v drugih raziskavah, gotovo predstavlja intertekst k Nonosovi epizodi. Motiv kače v vsebinskem in simbolnem smislu berem kot značilen primer Nonosove literarne sinteze krščanskega in klasičnega elementa, pri čemer je funkcija kače (varuhinja vhoda v sveti okraj) del klasičnega izročila, idejno ozadje epizode pa izvira iz krščanskega konteksta (idealizacija devištva in čistosti). Implicitne metafore v tem branju so eni strani razumevanje ženskega telesa kot svetega (okraja) in spolovila kot vhoda, ki ga varuje kača, ter na drugi strani – z ozirom na htonično naravo kače – razumevanje človeškega telesa kot zemeljskega elementa (v nasprotju z dušo, ki se povezuje z nebeškim).
Introduction
This study aimed to assess senior dental students' knowledge and attitudes regarding evidence‐based dentistry (EBD), their use of the current literature and considerations for patient ...preferences.
Materials and Methods
A modified Knowledge, Attitudes, Access, and Confidence Evaluation (KACE) survey was administered to collect data from senior dental students at the University of Maryland School of Dentistry (UMSOD). The chi‐squared test was used to compare the correct response rates of each question in the knowledge of scientific evidence domain. Spearman's rank correlation coefficient was conducted to examine correlations between students' knowledge of scientific evidence and their confidence in appraising the study qualities.
Results
61 seniors (out of 130) answered all survey questions. Participants displayed an intermediate level of knowledge of EBD. Only 15% of participants correctly answered to the most appropriate design; the distribution of responses appeared significantly different amongst the questions in the basic knowledge section (chi‐squared test, p < .0001). There was no or very weak correlation between students' knowledge of scientific evidence and their confidence in appraising study qualities (Spearman's ρ = 0–0.18). The participants highly valued the use of the current literature and patient preferences. However, their preferred sources of scientific evidence were the Internet excluding Cochrane reviews (60%) and colleagues (56%). Forty per cent of participants rarely or never used textbooks.
Conclusion
Whilst seniors felt confident in evaluating study qualities and implementing EBD in routine practice, their understanding of the study design was poor. Seniors' preferred sources of scientific evidence were non–peer‐reviewed Internet sources and colleagues.
The purpose of this study was to evaluate whether current educational strategies at a dental institution in the United States made a difference in dental hygiene (DNHY) and dental students' (D3) ...learning outcomes in the four domains of evidence-based practice (EBP), knowledge, attitude, accessing evidence, and confidence (KACE), following a 12-week research design course.
All participants DNHY (n=19) and D3 (n=96) enrolled in the research design course at Loma Linda University completed a paper KACE survey distributed on the first day of class. Students completed the KACE survey once more at the end of the 12-week course. Pre- and post-survey results were compared both within and between the DNHY and D3 student groups to identify the learning outcomes in the four domains of EBP; knowledge, attitude, accessing evidence, and confidence in EBP. Descriptive statistics were conducted to profile all variables in the study; the level of significance was set at α=0.05.
All DNHY students (n=19) completed the pre and post KACE surveys; of the D3 (n=96) students enrolled in the course 82% (n=79) competed the post-survey. Comparison of the survey results showed that both DNHY and D3 students demonstrated statistically significant increases in their level of knowledge and attitude (p < 0.05) towards EBP. In the attitude domain, DNHY students indicated more positive attitudes towards EBP (p < 0.001) than their D3 student cohorts. Neither group demonstrated significant changes in confidence in applying EBP (p > 0.05).
DNHY and D3 students increased their knowledge and developed more positive attitudes towards EBP following a 12-week research design course. Study results identify improvement areas for EBP knowledge acquisition including determining levels of evidence, analysis of study results, and evaluating the appropriateness of research study designs through the use of validated EBP survey instrument.

Wakimoto modules are representations of affine Kac–Moody algebras in Fock modules over infinite-dimensional Heisenberg algebras. In this paper, we present the construction of the Wakimoto modules ...from the point of view of the vertex algebra theory. We then use Wakimoto modules to identify the center of the completed universal enveloping algebra of an affine Kac–Moody algebra at the critical level with the algebra of functions on the space of opers for the Langlands dual group on the punctured disc, giving another proof of the theorem of B. Feigin and the author.

Dans cette thèse, nous étudions certaines équations différentielles partielles avec mécanisme dissipatif, telles que l'équation de Boltzmann, l'équation de Landau et certains systèmes hyperboliques ...symétriques avec type de dissipation. L'existence globale de solutions ou les taux de dégradation optimaux des solutions pour ces systèmes sont envisagées dans les espaces de Sobolev ou de Besov. Les propriétés de lissage des solutions sont également étudiées. Dans cette thèse, nous prouvons principalement les quatre suivants résultats, voir les chapitres 3-6 pour plus de détails. Pour le premier résultat, nous étudions le problème de Cauchy pour le non linéaire inhomogène équation de Landau avec des molécules Maxwelliennes (= 0). Voir des résultats connus pour l'équation de Boltzmann et l'équation de Landau, leur existence globale de solutions est principalement prouvée dans certains espaces de Sobolev (pondérés) et nécessite un indice de régularité élevé, voir Guo 62, une série d'oeuvres d'Alexander Morimoto-Ukai-Xu-Yang 5, 6, 7, 9 et des références à ce sujet. Récemment, Duan-Liu-Xu 52 et Morimoto-Sakamoto 145 ont obtenu les résultats de l'existence globale de solutions à l'équation de Boltzmann dans l'espace critique de Besov. Motivés par leurs oeuvres, nous établissons l'existence globale de la solution dans des espaces de Besov spatialement critiques dans le cadre de perturbation. Précisément, si le datum initial est une petite perturbation de la distribution d'équilibre dans l'espace Chemin-Lerner eL 2v (B3=2 2;1 ), alors le problème de Cauchy de Landau admet qu'une solution globale appartient à eL 1t eL 2v (B3=2 2;1 ). Notre résultat améliore le résultat dans 62 et étend le résultat d'existence globale de l'équation de Boltzmann dans 52, 145 à l'équation de Landau. Deuxièmement, nous considérons le problème de Cauchy pour l'équation de Kac non-coupée spatialement inhomogène. Lerner-Morimoto-Pravda-Starov-Xu a considéré l'équation de Kac non-coupée spatialement inhomogène dans les espaces de Sobolev et a montré que le problème de Cauchy pour la fluctuation autour de la distribution maxwellienne admise S 1+ 1 2s 1+ 1 2s Propriétés de régularité Gelfand-Shilov par rapport à la variable de vélocité et propriétés de régularisation G1+ 1 2s Gevrey à la variable de position. Et les auteurs ont supposé qu'il restait encore à déterminer si les indices de régularité 1 + 1 2s étaient nets ou non. Dans cette thèse, si la donnée initiale appartient à l'espace de Besov spatialement critique, nous pouvons prouver que l'équation de Kac inhomogène est bien posée dans un cadre de perturbation. De plus, il est montré que la solution bénéficie des propriétés de régularisation de Gelfand-Shilov en ce qui concerne la variable de vitesse et des propriétés de régularisation de Gevrey en ce qui concerne la variable de position. Dans notre thèse, l'indice de régularité de Gelfand-Shilov est amélioré pour être optimal. Et ce résultat est le premier qui présente un effet de lissage pour l'équation cinétique dans les espaces de Besov. A propos du troisième résultat, nous considérons les équations de Navier-Stokes-Maxwell compressibles apparaissant dans la physique des plasmas, qui est un exemple concret de systèmes composites hyperboliques-paraboliques à dissipation non symétrique. On observe que le problème de Cauchy pour les équations de Navier-Stokes-Maxwell admet le mécanisme dissipatif de type perte de régularité. Par conséquent, une régularité plus élevée est généralement nécessaire pour obtenir le taux de dégradation optimal de L1(R3)-L2(R3) type, en comparaison avec cela pour l'existence globale dans le temps de solutions lisses.
In this thesis, we study some kinetic equations and some partial differential equations with dissipative mechanism, such as Boltzmann equation, Landau equation and some non-symmetric hyperbolic systems with dissipation type. Global existence of solutions or optimal decay rates of solutions for these systems are considered in Sobolev spaces or Besov spaces. Also the smoothing properties of solutions are studied. In this thesis, we mainly prove the following four results, see Chapters 3-6 for more details. For the _rst result, we investigate the Cauchy problem for the inhomogeneous nonlinear Landau equation with Maxwellian molecules ( = 0). See from some known results for Boltzmann equation and Landau equation, their global existence of solutions are mainly proved in some (weighted) Sobolev spaces and require a high regularity index, see Guo 62, a series works of Alexandre-Morimoto-Ukai-Xu-Yang 5, 6, 7, 9 and references therein. Recently, Duan-Liu-Xu 52 and Morimoto-Sakamoto 145 obtained the global existence results of solutions to the Boltzmann equation in critical Besov spaces. Motivated by their works, we establish the global existence of solutions for Landau equation in spatially critical Besov spaces in perturbation framework. Precisely, if the initial datum is a small perturbation of the equilibrium distribution in the Chemin-Lerner space eL 2v (B3=2 2;1 ), then the Cauchy problem of Landau equation admits a global solution belongs to eL 1t eL 2v (B3=2 2;1 ). Our results improve the result in 62 and extend the global existence result for Boltzmann equation in 52, 145 to Landau equation. Secondly, we consider the Cauchy problem for the spatially nhomogeneous non-cuto_ Kac equation. Lerner-Morimoto-Pravda-Starov-Xu 117 considered the spatially inhomogeneous non-cuto_ Kac equation in Sobolev spaces and showed that the Cauchy problem for the uctuation around the Maxwellian distribution admitted S 1+ 1 2s 1+ 1 2s Gelfand-Shilov regularity properties with respect to the velocity variable and G1+ 1 2s Gevrey regularizing properties with respect to the position variable. And the authors conjectured that it remained still open to determine whether the regularity indices 1+ 1 2s is sharp or not. In this thesis, if the initial datum belongs to the spatially critical Besov space eL 2v (B1=2 2;1 ), we prove the well-posedness to the inhomogeneous Kac equation under a perturbation framework. Furthermore, it is shown that the weak solution enjoys S 3s+1 2s(s+1) 3s+1 2s(s+1) Gelfand-Shilov regularizing properties with respect to the velocity variableand G1+ 1 2s Gevrey regularizing properties with respect to the position variable. In our results, the Gelfand-Shilov regularity index is improved to be optimal. And this result is the _rst one that exhibits smoothing e_ect for the kinetic equation in Besov spaces. About the third result, we consider compressible Navier-Stokes-Maxwell equations arising in plasmas physics, which is a concrete example of hyperbolic-parabolic composite systems with non-symmetric dissipation. It is observed that the Cauchy problem for Navier-Stokes-Maxwell equations admits the dissipative mechanism of regularity-loss type. Consequently, extra higher regularity is usually needed to obtain the optimal decay rate of L1(R3)-L2(R3) type, in comparison with that for the global-in-time existence of smooth solutions.
