  • A total of 98 vancomycin-resistant Enterococcus faecium (VREF) isolates (58 isolates from patients and 40 isolates from poultry) were compared based on their antimicrobial susceptibility, Tn1546 element organization, and pulsed-field gel electrophoresis (PFGE) patterns. This comparison aided in determining the relationships between the groups of isolates. All the VREF isolates harbored the vanA gene; however, 29 (29.6%) of the isolates exhibited the VanB phenotype-vanA genotype. Furthermore, the VREF isolates from humans and poultry exhibited distinct antimicrobial resistance patterns. The PCR mapping of the Tn1546 elements exhibited 12 different transposon types (A to L). The VREF isolates of poultry were classified into types A to D, whereas the human isolates were classified into types E to L. A PFGE analysis demonstrated a high degree of clonal heterogeneity in both groups of isolates; however, the distinct VREF clones appeared in each group of isolates. The deletion of the vanX-vanY genes or insertion of IS1216V in the intergenic region from the vanX-vanY genes is directly associated with the incongruence of the VanB phenotype-vanA genotype in human VREF isolates. These data suggest that the VREF isolates exhibit distinct phenotypic and genotypic traits according to their origins, which suggests that no evidence exists to substantiate the clonal spread or transfer of vancomycin resistance determinants between humans and poultry.

  • Lake Van Basin, located in Eastern Turkey, is worth examining in terms of seismicity due to large-scale losses of property and life during the historical and instrumental period. The most important and largest province in this basin is Van. Recent indicators of the high seismicity risk in the province are damage occurring after devastating earthquakes in 2011 (Mw=7.2 and Mw=5.6) and lastly in 2020 Khoy (Mw=5.9). The seismic hazard analysis for Van and its districts in Eastern Turkey was performed in probabilistic manner. Analyses were made for thirteen different districts in Van. In this study, information is given about the tectonic setting and seismicity of Van. The probabilistic seismic hazard curves were obtained for a probability of exceedance of 2%, 10% and 50% in 50-year periods. The PGA values in the Van province vary from 0.24 g - 0.43 g for earthquakes with repetition period of 475 years. Risk priorities were determined for all districts. The highest risk was calculated for Çaldıran and the lowest risk was found for Gürpınar. Risk priorities for buildings in all districts were also determined via rapid seismic assessment for reinforced-concrete and masonry buildings in this study.

  • In general, the idea of fun is understood to be associated with interesting things, playfulnesses, joy, pleasure, etc. The "fun culture," which seeks enjoyment and pleasure through life, is a characteristic of elements observed in today's society and culture. This exerts a powerful impacts on the business operation, marketing, and product manufacturing. Moreover, it is accepted as one of remarkable phenomena representing the changing trends of fashion in the 21st century. The objectives of this study were to analyze and categorize the fun motifs observed in fashion designer Walter Van Beirendonck 's collections, to examine their formative characteristics, and to establish academic approaches and analytic framework in studying the fun phenomenon emerging in fashion. As to research methods, this study laid a theoretical ground by reviewing the related literature and previous studies, and conducted a positive case study using the data on Walter Van Beirendonck's collections and exhibitions. According to the results of this study, the fun motifs represented in Walter Van Beirendonck's collections are largely categorized into "deviation from rules," "humorous and obscene graphic images," "introduction and transformation of heterogeneous elements," "women with male gender' etc. On the other side of Walter Van Beirendonck's fashion are sex, sexual humors, sexuality, fetishism, love, form, body, language, social phenomena, harmony between nature and life, consumerism, race, shamanism, tribal rituals, nation, cultural collision, transcendent things, science fictions, cyber Space, dream, alien, future, fairytale, fantasy etc. which are expressed by using fun motifs. Moreover, these themes are led to masculinity and fantasy.

  • This study was carried out in order to test unsaturated hydraulic conductivity estimation of van Genuchten's and Campbell's models using one-step outflow method through Tempe pressure cell. The undisturbed soil cores (columns) were taken from Ap1, B1 and C horizons of Songjeong series (the fine loamy, mesic family of Typic Hapludults). After the saturated hydraulic conductivity Ks of the cores was determined by constant head method, water outflow rate and retentivity of cores were measured in Tempe pressure cell. Fitted curves by models accorded to measured data except for both end of pressure range. In near-saturated condition, measured water retention characteristics showed a relatively better fitness with Campbell's model than van Genuchten's. The soil unsaturated conductivity estimated by Campbell's model was higher than by van Genuchten's. In Ap1 and B1 horizon, the soil unsaturated conductivities obtained by one-step outflow method went between van Genuchten's and Campbell's hydraulic functions, slightly closer to van Genuchten's. In C horizon, van Genuchten's model had better fitness with the one-step outflow data. Consequently, van Genuchten's model generally had better fitness with measured hydraulic conductivity than Campbell's model at the soil water potential range of -10~-75 kPa, especially in C1 horizon. In near-saturated condition, Campbell's model could be thought as relatively accurate hydraulic model, because of the better fitness of Campbell's model with soil water retention data than van Genuchten's model.

  • In this study, using the VITEK 2 system, 74 samples (22.6%) out of 327 specimens were identified by the growth of Enterococcosel media (EV6 agar) supplemented with $6{\mu}g/mL$ of vancomycin. Enterococcus faecium was identified as 55 strains (74.3%), Enterococcus casseliflavus as 2 strains (2.7%), Enterococcus avium as 1 strain (1.4%), and Enterococcus gallinarum as 16 strains (21.6%). Among the 55 phenotypes of Enterococcus faecium, 42 (76.4%), 9 (16.4%), and 4 strains (7.3%) showed the vanA, vanB, and vanC phenotype, respectively. The 16 strains of Enterococcus gallinarum and 2 strains of Enterococcus casseliflavus showed the vanC phenotype and the 1 strain of Enterococcus avium had the vanB phenotype. The one strain of Enterococcus faecium propagated only in EV4 and was susceptible to both vancomycin and teicoplanin according to the antimicrobial susceptibility test using the VITEK 2 system. The vancomycin resistance phenotype gene was not detected by PCR. A total of 327 specimens were cultured in Enterococcosel broth supplemented with $6{\mu}g/mL$ of vancomycin (EV6 broth), and 120 strains (36.7%) were isolated. These 120 strains were subjected to vancomycin resistant genotyping by a multiplex real-time polymerase chain reaction and 51 strains (42.5%) showed vanA; 5 strains (4.2%) showed vanA and vanC; and 18 strains (15%) showed vanC. Vancomycin resistance genotypes were not detected in the remaining 46 strains (38.3%).

  • We present a high-resolution van Leer-type numerical scheme for the isentropic model of fluid flows in a nozzle with variable cross-section. Basically, the scheme is an improvement of the Godunov-type scheme. The scheme is shown to be well-balanced, as it can capture exactly equilibrium states. Numerical tests are conducted which include comparisons between the van Leer-type scheme and the Godunov-type scheme. It is shown that the van Leer-type scheme achieves a very good accuracy for initial data belong to both supersonic and supersonic regions, and the exact solution eventually possesses a resonant phenomenon.

  • This study aims to consider characteristics of the scenography in terms of directorial viewpoints of Belgian director Ivo Van Hove(1958~) and define indefinite realities through his production, The Fountainhead. Van Hove has gained worldwide fame with his dramatic and spectacular stage production and audience participation in his production Roman Tragedies. I paid attention to the spatial aesthetics of director Van Hove, which supports such bold stage production. I believed that his philosophy of space would exist behind his sophisticated space concept. Also, if you look closely at his work's spatial characteristics, you will find elements that capture the essence of his work and lead to a performative transition of the audience. Therefore, I would like to find out in detail how these elements were applied to the work The Fountainhead and conduct researches on the spatial characteristics of Van Hove's production. In particular, The Fountainhead shows a unique stage language through Van Hove's space production, and it is considered as the best work to study the characteristics of Van Hove's space production through a hero architect Howard Roak. In other words, I judged that through Roark as a persona, I could find a link between Van Hove's spatial aesthetics and directorial scenography. I hope that active following researches on Van Hove's spatial aesthetics could be conducted in the future, and this study would be a small starting point for his research on directorial scenography.
