[source] Dental school admissions in Ireland: can current selection criteria predict success?EUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 2 2006C. D. Lynch Introduction:, Entry into university education in Ireland, including dental school, is based solely on academic performance in the Leaving Certificate Examination, held at the end of formal school education. The aim of this investigation was to examine the suitability of this process for the selection of dental students in Ireland. Materials and methods:, Information for all dental students who entered the dental degree programme immediately following completion of the Leaving Certificate Examination at the National University of Ireland, Cork, during the years 1997,1999 was retrieved. Information was collected relating to gender, the number of times the student had attempted the Leaving Certificate Examination, their performance in this examination, the total number of marks awarded to each student at the end of the First and Final Dental Examinations, and their performance in individual modules. Results:, Whilst there was a significant relationship between performance in the Leaving Certificate Examination and the First Dental Examination (correlation coefficient = 0.22, P < 0.05), this relationship could only explain 12% of the variation within the performance of students in this examination. There was no relationship between performance in the Leaving Certificate and the Final Dental Examination (correlation coefficient = 0.09, P > 0.05). There was a significant correlation between performance in the Leaving Certificate Examination and performance in seven of the 55 programme modules, all of which were pre-clinical modules, and of which five were related to basic sciences. Conclusions:, Based on the limitations of this study, the current selection process for dental students in Ireland seems to be of limited value. [source] Stereotyping in the Representation of Narrative Texts Through Visual ReformulationsFOREIGN LANGUAGE ANNALS, Issue 3 2003Article first published online: 31 DEC 200, Melina Porto MA Two hundred nineteen visual reformulations produced in response to three narrative texts about Christmas celebrations were analyzed (one in Spanish, the subjects' native tongue, and two in English as a foreign language). Subjects were Argentine college students (prospective teachers and translators of English, Caucasian, mostly female, middle-class) between 19 and 21 years of age enrolled in English Language II at the National University of La Plata in Argentina. Stereotypes in the visual reformulations were classified into two large groups: those corresponding to the native culture and those referring to the target (alien) culture. Stereotypes were further classified into three categories of reference: main characters (personality and/or physical appearance), the Christmas celebration itself, and the storyline. A selection of typical visual reformulations is analyzed here. In general, the visual reformulations did not sufficiently capture the cultural content of the texts and embodied a superficial approach plagued with stereotypes. The students' perceptions of otherness were limited to what was exotic or exciting and did not reflect genuine efforts to become familiar with what was strange. The study thus revealed the learners' inability to transcend their cultural biases and points to an urgent need to address stereotypes in the classroom. [source] Daily streamflow modelling and assessment based on the curve-number techniqueHYDROLOGICAL PROCESSES, Issue 16 2002Jin-Yong Choi Abstract A cell-based long-term hydrological model (CELTHYM) that can be integrated with a geographical information system (GIS) was developed to predict continuous stream flow from small agricultural watersheds. The CELTHYM uses a cell-by-cell soil moisture balance approach. For surface runoff estimation, the curve number technique considering soil moisture on a daily basis was used, and release rate was used to estimate baseflow. Evapotranspiration was computed using the FAO modified Penman equation that considered land-use-based crop coefficients, soil moisture and the influence of topography on radiation. A rice paddy field water budget model was also adapted for the specific application of the model to East Asia. Model sensitivity analysis was conducted to obtain operational information about the model calibration parameters. The CELTHYM was calibrated and verified with measured runoff data from the WS#1 and WS#3 watersheds of the Seoul National University, Department of Agricultural Engineering, in Hwaseong County, Kyounggi Province, South Korea. The WS#1 watershed is comprised of about 35·4% rice paddy fields and 42·3% forest, whereas the WS#3 watershed is about 85·0% forest and 11·5% rice paddy fields. The CELTHYM was calibrated for the parameter release rate, K, and soil moisture storage coefficient, STC, and results were compared with the measured runoff data for 1986. The validation results for WS#1 considering all daily stream flow were poor with R2, E2 and RMSE having values of 0·40, ,6·63 and 9·69 (mm), respectively, but validation results for days without rainfall were statistically significant (R2 = 0·66). Results for WS#3 showed good agreement with observed data for all days, and R2, E2 and RMSE were 0·92, 0·91 and 2·23 (mm), respectively, suggesting potential for CELTHYM application to other watersheds. The direct runoff and water balance components for watershed WS#1 with significant areas of paddy fields did not perform well, suggesting that additional study of these components is needed.

[source] Experimental study of the use of additives in the performance of a single-stage heat transformer operating with water,lithium bromideINTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 2 2005W. Rivera Abstract In the present paper, the additives 1-octanol and 2-ethyl-1-hexanol, have been used for the first time in a 2 kW single-stage heat transformer installed in the Energy Research Centre of the National University of Mexico utilizing H2O/LiBr, operating at absorber temperatures in a range between 70 and 110°C. The results showed that at the same conditions, absorber temperatures increased about 5°C by adding 400 ppm of 2-ethyl-1-hexanol to the lithium bromide mixture. Also it was shown that the coefficient of performance increases up to 40% with the same additive. Copyright © 2005 John Wiley & Sons, Ltd. [source] Preoperative staging of gastric cancer by endoscopic ultrasonography and multidetector-row computed tomographyJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 3 2010Sung Wook Hwang Abstract Background and Aim:, The aim of this study was to determine the accuracy of endoscopic ultrasonography (EUS) and multidetector-row computed tomography (MDCT) for the locoregional staging of gastric cancer. EUS and computed tomography (CT) are valuable tools for the preoperative evaluation of gastric cancer. With the introduction of new therapeutic options and the recent improvements in CT technology, further evaluation of the diagnostic accuracy of EUS and MDCT is needed. Methods:, In total, 277 patients who underwent EUS and MDCT, followed by gastrectomy or endoscopic resection at Bundang Hospital, Seoul National University, from July 2006 to April 2008, were analyzed. The results from the preoperative EUS and MDCT were compared to the postoperative pathological findings. Results:, Among the 277 patients, the overall accuracy of EUS and MDCT for T staging was 74.7% and 76.9%, respectively. Among the 141 patients with visualized primary lesions on MDCT, the overall accuracy of EUS and MDCT for T staging was 61.7% and 63.8%, respectively. The overall accuracy for N staging was 66% and 62.8%, respectively. The performance of EUS and MDCT for large lesions and lesions at the cardia and angle had significantly lower accuracy than that of other groups. For EUS, the early gastric cancer lesions with ulcerative changes had significantly lower accuracy than those without ulcerative changes. Conclusions:, For the preoperative assessment of individual T and N staging in patients with gastric cancer, the accuracy of MDCT was close to that of EUS. Both EUS and MDCT are useful complementary modalities for the locoregional staging of gastric cancer. [source] POPULATION DYNAMICS AND THE TOXICITY OF BLUE-GREEN ALGAE IN THE NAKTONG RIVER, KOREAJOURNAL OF PHYCOLOGY, Issue 2001Article first published online: 24 SEP 200 Lee, J. A.1, Choi, A. R.1, Park, J. H.1 & Chung, I. K2 1Department of Environmental Science, Inje University, Kimhae 621-749, Korea; 2Departement of Marine Science, Pusan National University, Pusan 609-735, Korea Seasonal and spatial variations of phytoplankton community were monitored at 16 sites along the Naktong River. Blue-green algae appeared from May through November with dominant genera of Microcystis, Anabaena, Oscillatoria and Gomphosphaeria. Frequency and biomass of the genera became greater at lower reaches. The Microcystis were observed from May to October up to 85,750cells/ml. Six species of Microcystis were identified with morphological characteristics and M. aeruginosa was most dominant. There were significant relationships between biomass of Microcystis and NO -3, TP and pH in water column. However, NH4+, PO4 -3 and N/P were not critical in successions to the Microcystis dominated community. Microcystis blooms were notable at water temperature higher than 25°C. Microcystis density in sediment was 3 orders of magnitude higher than water column. Anabaena density ranged up to 11,220cells/ml. Four species of Anabaena were identified and A. flos-aquae was most dominant. Anabaena biomass was not related to temperature, NO3 - , TN, PO4 -3, TP and N/P of water column and the frequency of trichome with akinete and/or heterocyte were not related to these parameters. Microcystins were detected from May to November with yearly fluctuations. Microcystin-RR was most dominant. Total 84.2% of algal materials with Microcystis exhibited toxicity of microcystin with maximum of 3,292,g/g dry wt. Total 12.5% of water column with Microcystis exhibited dissolved microcystin up to 3.3,g/l. Microcystin concentrations were positively related to Microcystis biomass and pH of water column. Anatoxin-a was determined by FD-HPLC analysis with NBD-F and all concentrations were below the detection limit of 0.1,g/l. [source] ULTRASTRUCTURE OF THE BASAL BODY COMPLEX AND PUTATIVE VESTIGIAL FEEDING APPARATUS IN PHACUS PLEURONECTES (EUGLENOPHYCEAE)JOURNAL OF PHYCOLOGY, Issue 2001Article first published online: 24 SEP 200 Shin, W.1, Boo, S. M.2, & Triemer, R. E.1 1Department of Life Science, Rutgers University, Piscataway, New Jersey 08854, USA; 2Department of Biology, Chungnam National University, Daejon 305-764, Korea Phacus pleuronectes (O. F. Müller) Dujardin is a phototrophic euglenoid with small discoid chloroplasts, a flat, rigid body, and longitudinally arranged pellicular strips. The flagellar apparatus consisted of two basal bodies and three flagellar roots typical of many phototrophic euglenoids, but also had a large striated fiber that connected the two basal bodies and associated with the ventral root. The three roots, in combination with the dorsal microtubular band, extended anteriorly and formed the major cytoskeletal elements supporting the reservoir membrane and ultimately the pellicle. A cytoplasmic pocket arose in the reservoir/canal transition region. It was supported by the ventral root and a C-shaped band of electron-opaque material that lined the cytoplasmic side of the pocket. A large striated fiber extended from this C-shaped band toward the reservoir membrane. The presence of striated fibers in the basal apparatus and associated with the microtubule reinforced pocket suggested that P. pleuronectes may be at the base of the Phacus lineage and may be more closely related to the phagotrophic euglenoids than to Phacus species which are ovoid in shape and have thicker pellicle strips. [source] More carrots than sticks: Antanas Mockus's civic culture policy in BogotáNEW DIRECTIONS FOR YOUTH DEVELOPMENT, Issue 125 2010Felipe Cala Buendía The son of a Lithuanian artist, Antanas Mockus was the president of the National University in Colombia before he became mayor of Bogotá in 1995. As mayor, he transformed the city into a huge classroom, not only bringing to his administration a new view of governing but also transforming the way people exercised their citizenship. Mockus resorted to a creative communicative and pedagogical effort to change the citizens' hearts and minds in favor of peaceful coexistence and legal compliance. Symbols, metaphors, and humor became the language through which the administration would enforce its measures to deal with urban violence. Unconventional techniques, such as a symbolic vaccine against domestic violence and the use of mimes to control traffic circulation and create a sense of shame among those who committed infractions, helped to stop crime and develop a new sense of citizenship.

[source] Abstracts presented for publication of the June 4,6, 2009, I Argentine Congress of Veterinary Morphological Sciences, National University of Rosario, Rosario, Santa Fe, ArgentinaANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 1 2010Article first published online: 13 JAN 2010 First page of article [source] SLA typing using the PCR-SSP method and establishment of the SLA homozygote line in pedigreed SNU miniature pigsANIMAL SCIENCE JOURNAL, Issue 2 2010Su-Cheong YEOM ABSTRACT Seoul National University (SNU) miniature pigs represent a closed colony with 24 founder pigs and a well preserved pedigree. Characterization using mRNA sequence analysis was conducted for 6 swine leukocyte antigen (SLA) loci in parental or founder pigs, and 17 defined alleles were detected. Based on these complete coding sequences, 17 sequence specific primers (SSPs) were designed for polymorphic sites. To validate the specificity of each allele SSP, the PCR-SSP was conducted with defined allele clones as templates. PCR-SSP was conducted with the hot start polymerase and touch-down PCR. The parental or found SNU miniature pigs showed overall SLA class I and II heterozygotes. Using the established PCR-SSP method, we conducted SLA typing for breeding stock including 2 pedigreed pigs and identified the novel SLA class II homozygote haplotye (DRA*0201, DRB1*0403, DQA*0102 and DQB1*0701) and 2 SLA homozygote pig lines: SLA class I Hp-3.0 and class II Hp-0.3, and SLA class I Hp-2.0 and class II Hp-0.2. We thought that our PCR-SSP SLA typing method could be applicable for new SLA homozygote line establishment by assignment and scheduled breeding. [source] Phylogenetic analysis for the Seoul National University (Minnesota) miniature pig by mitochondrial DNA sequence polymorphismANIMAL SCIENCE JOURNAL, Issue 2 2010Su-Cheong YEOM ABSTRACT Seoul National University (SNU) miniature pigs are originated from the Minnesota miniature pig. This study was conducted to investigate the maternal origin of SNU (Minnesota) miniature pigs and their phylogenetic relationships by analyzing the mitochondrial DNA (mtDNA) D-loop (control region) sequence. Two mtDNA D-loop sequences of the SNU miniature pigs were identified. On an unweighted pair-group method with an arithmetic mean (UPGMA) phylogenetic tree analysis, the large white was the pig breed closest to the SNU miniature pig, and the pairwise distance analysis showed the same result. While mtDNA sequences of 4 pig breeds which were used to establish Minnesota miniature pig were not known, our result might be different from the history of the Minnesota miniature pig development. In conclusion, we thought that some haplotypes of the Minnesota miniature pig maternally were originated from the Large white pig, or that wild pigs had similar mtDNA sequences to the Large white pig, and all SNU miniature pigs were derived from this colony. [source] Optimal Moving Angle of Pusher Plate in Occlusive-Type Pulsatile Blood PumpARTIFICIAL ORGANS, Issue 7 2010Hyuk Choi Abstract Since the occlusive-type pulsatile extracorporeal blood pump (Twin-Pulse Life Support System; Seoul National University, Seoul, Korea) received the CE mark of the European Directives and Korea Food and Drug Administration approval (2004) for short-term applications as an extracorporeal life support system, the pump system has been tested for hemolysis. This pump system was recently upgraded with an ameliorated pusher plate to reduce hemolysis. In this study, numerical analysis and in vitro tests were performed to determine the optimal conditions for increasing the durability of the blood sac and pump output. During the simulation, the minimum sliding interface force (SIF) for the angle of the pusher plate movement (PPM) was calculated (40,70°). In the in vitro durability test, the angle of the PPM was increased gradually from 40 to 70° in 10° increments, and the mean time to failure (MTTF) of the blood sac was calculated. Fifteen tests were conducted for each case: 40, 50, 60, and 70° (n = 15 each). The MTTF of the blood sac was defined as the time when a crack of the blood sac occurred. The longer lifetime of the blood sac at 60° of the PPM (297.0 h) than that at 50° (197.6 h) was attributed to the lower SIF value (,0.13, normalized value) at 60° of the PPM. [source] Scientific instrumentation for the 1.6 m New Solar Telescope in Big BearASTRONOMISCHE NACHRICHTEN, Issue 6 2010W. Cao Abstract The NST (New Solar Telescope), a 1.6 m clear aperture, off-axis telescope, is in its commissioning phase at Big Bear Solar Observatory (BBSO). It will be the most capable, largest aperture solar telescope in the US until the 4 m ATST (Advanced Technology Solar Telescope) comes on-line late in the next decade. The NST will be outfitted with state-of-the-art scientific instruments at the Nasmyth focus on the telescope floor and in the Coudé Lab beneath the telescope. At the Nasmyth focus, several filtergraphs already in routine operation have offered high spatial resolution photometry in TiO 706 nm, H, 656 nm, G-band 430 nm and the near infrared (NIR), with the aid of a correlation tracker and image reconstruction system. Also, a Cryogenic Infrared Spectrograph (CYRA) is being developed to supply high signal-to-noise-ratio spectrometry and polarimetry spanning 1.0 to 5.0 ,m. The Coudé Lab instrumentation will include Adaptive Optics (AO), InfraRed Imaging Magnetograph (IRIM), Visible Imaging Magnetograph (VIM), and Fast Imaging Solar Spectrograph (FISS). A 308 sub-aperture (349-actuator deformable mirror) AO system will enable nearly diffraction limited observations over the NST's principal operating wavelengths from 0.4 ,m through 1.7 ,m. IRIM and VIM are Fabry-Pérot based narrow-band tunable filters, which provide high resolution two-dimensional spectroscopic and polarimetric imaging in the NIR and visible respectively. FISS is a collaboration between BBSO and Seoul National University focussing on chromosphere dynamics. This paper reports the up-to-date progress on these instruments including an overview of each instrument and details of the current state of design, integration, calibration and setup/testing on the NST (© 2010 WILEY-VCH Verlag GmbH & Co.

The study was carried out in a rural area of central Argentina, from 1983 to 2003. Density was estimated as a relative density index (RDI). Temperature, precipitation and humidity were obtained from records of the National University of Rio Cuarto. Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature were recorded from National Oceanic and Atmospheric Administration (1983,1998) and Landsat (1998,2003) imagery data sets. We performed simple correlations, multiple regressions and distributed lag analysis. Direct association of climatic and environmental variables with RDI was in general, low. The amount of variability in seasonal changes in density explained by climatic and environmental variables altogether varied from 10% to 70%. Seasonal population fluctuations were influenced by NDVI and rainfall with one and two seasons of delay. Autumn maximum density of the species was also associated with vegetation and rainfall of previous seasons. There also seemed to be an indirect influence of rainfall through vegetation given that we found a positive correlation between them. Results were consistent with basic aspects of the ecology of the species, such as its strong preference for highly covered areas, which provide food and protection from predators, likely increasing its reproductive success. Therefore, in the rural area central Argentina, A. azarae showed seasonal fluctuations with delayed influence of rainfall and vegetation and indirect effects of rainfall.
