Pavlína Šumníková, Ph.D., Praha 2010 ANNOTATION: The work deals with identifying the level of olfactory perception among people with severe visual impairment. The aim is to compare the function of olfactory discrimination and olfactory threshold sensitivity among persons with congenital or acquired visual handicap. The theoretical section presents the basic anatomical and physiological characteristics of the olfactory system, the list of disorders of smell and olfactory testing methods in clinical practice, and a brief account of visual impairments. The empirical investigation is carried out using standardized tests, olfactory discrimination function is measured by a test of the University of Pennsylvania Smell Identification Test (UPSIT), olfactory perception threshold using the Smell Threshold Test (STT). The thesis describes in detail both the methods and characteristics of groups of test subjects. In the analytical part it focuses on the comparison of test results among persons with congenital or acquired severe visual impairment.

Asperger syndrome and high-functioning autism is a form of pervasive developmental disorder characterized by impaired social interaction and communication and restricted and stereotyped interests. These children are often clumsy and motor uncoordinated. They also performed worse in standardized tests of motor function. In this diploma thesis we used Movement Assessment Battery for Children 2 (MABC-2) for assessment motor skills in children with Asperger syndrome and high-functioning autism aged 7-10 years in comparison with the group of children developing typically. Our study included 9 children with Asperger syndrome, 3 children with high-functioning autism and 64 children with typical development. Evident motor deficit (below 5. percentile) was found in 2 children with Asperger syndrome and 3 children with high-functioning autism. 1 child with Asperger syndrome was in a risk of motor deficit (6.-16. percentile). Children with Asperger syndrome and high-functioning autism performed significantly worse than children developing typically in a total score of this test. Significant difference was found in two components of MABC-2, in Aiming and catching (AC) and Balance (BAL). Better results reached children with typical development. Results of this study indicate that children with Asperger syndrome...

Examensarbetet syftar till att uppmärksamma kvalitetsavvikelser i produktionen på ett internationellt företag som säljer kundanpassade transportlösningar inom logistik och lagerhantering. Med hjälp av en arbetsmetod, kallad Näranalys, ska tillvägagångssättet att hantera en kvalitetsavvikelse förbättras. Anledningen till implementeringen är att komma underfund med grundorsakerna till avvikelser samt att bearbeta dessa för att reducera risken för återkomst. Fel och brister som uppkommer i alla verksamheter kan definieras som kvalitetsbristkostnader och kan, enligt Sörqvist, bestå av uppemot 30 % av ett företags totala omsättning och är därför väsentligt att minimera (2001).Utifrån organisationsfilosofin Lean Management med dess verktyg och metoder har ett antal aspekter framstått som väsentliga för att en implementering av en arbetsmetod ska bli lyckad. Att reflektera över hur filosofins standardisering kan komma att bidra till psykosociala påfrestningar kan en mer hållbar och prefererande arbetsgång tas fram utifrån olika branscher och förutsättningar. En avgörande faktor ur studiens utfall är medvetenheten kring den framtagna arbetsmetoden. Det är därav viktigt att ett förtydligande sker gällande att arbetsmetoden inte skapades för övervakning mot enskilda individer, utan för att förbättra arbetssättet och skapa förutsättningar för operatörer att göra rätt från första början.Nyckelord: Lean, / This thesis aims to pay attention to quality deviations in the production of an international company that export customized transport logistics and inventory management. With the help of a working method, called Näranalys, should approaches to manage a quality deviation be improved. The reason to the implementation is to figure out the root causes of deviations and to process them in order to reduce the risk of recurrence. Faults and defects arising in all activities can be defined as the quality deficiency cost and may, according to Sörqvist, consist of up to 30% of a total turnover and is therefore essential to minimize (2001).Based on the organization philosophy Lean Management, a number of aspects have been identified as essential for the implementation of a working method to succeed. Reflecting on how the philosophy of standardization can contribute to psychosocial stresses is an important part of the studie. A crucial factor in the outcome of the study is the awareness of the working method. It is therefore important to clarify that the working method was not created for monitoring individuals, but to improve the way in which work is done and to create the conditions for operators to have the right circumstances to make a good job from the start.

Att kartlägga hur ett företags olika processer ser ut är en viktig del ur ett kontinuerligtförbättringsarbete.

An examination of the characteristics of Texas middle schools has been conducted with the objective of developing a planning tool for middle staffs. This success is measured by the Academic Excellence Indicator System (AEIS), whose rating scale has three components: campus scores on the Texas Assessment of Basic Skills (TAAS), campus attendance percentages, and campus dropout rates. TAAS scores and attendance rates have been the focus of this study. Two years of data were examined separately for research question. Principal component analysis reduced the number of indicators in both years' data to 20 factors/ Each of these factors received a designated based on the characteristics that the component indicators had in common. A multiple regression analysis was performed on these factors to determine the influence each had on the campus TAAS scores and attendance. The unpredictability of human subjects requires an additional step in this study to achieve valid conclusions. A comparison of the two years' results is made to discover attendance, gifted and talented programs, and teacher gender were the strongest overall positive influences on student achievement. Campus demographics, retention, and ESL/bilingual programs have the strongest association with low student achievement.

En svensk skolkommuns ambitioner har varit att klättra på skolrankingen. Ett sätt att göra detta är att utforma ett kommunalt matematikprov för årskurs 5 i syfte att upptäcka kunskapsluckor i god tid innan det nationella provet i årskurs 6. Syftet med studien är att undersöka hur detta prov påverkar matematiklärarnas arbete. Detta har undersökts genom kvalitativa intervjuer av de berörda matematiklärarna. Svaren har analyserats utifrån den teoretiska utgångspunkten sociomatematiska normer. Vi har också analyserat det matematiska innehållet i ett arbetsmaterial som kommunen har uppmanat lärarna till att använda som förberedande material. Resultatet pekar på att matematiklärares arbete påverkas i hög grad av att huvudmannen anordnar ett centralstyrt matematikprov. Detta gäller det matematiska innehållet i deras undervisning och därmed de sociomatematiska normer som råder i klassrummen. Vår slutsats är att kommunens intention att påverka lärarnas arbete infrias, men hur det på längre sikt påverkar elevers kunskapsutveckling återstår att undersöka. / A Swedish school municipality's ambitions has been to climb the school rankings. One way of doing this is to design a test for fifth grade pupils in order to discover gaps in students mathematical understandning well ahead of the national tests in the sixth grade. The purpose of this study is to investigate how this test affects the work of mathematics teachers. This has been investigated through qualitative interviews of the involved mathematics teachers. The data have been analyzed based on the theoretical starting point of socio-mathematical norms. We have also analyzed the mathematical content that the municipality has recommended the teachers to use as preparatory material. The result indicates that the work of mathematics teachers is very much influenced by the fact that the municipality organizes a central-controlled mathematics test. This applies to the mathematical content of their teaching and the socio-mathematical norms prevailing in the classrooms. Our conclusion is that the municipality can influence and alter the teachers' work both inside and outside the math class.

A planta Psidium guajava Linn. (Myrtaceae), popularmente conhecida por goiabeira, é muito utilizada na medicina tradicional devido às suas propriedades antioxidante, antimicrobiana e anti-inflamatória. O objetivo deste trabalho foi a obtenção, padronização e avaliação das atividades biológicas de extratos secos de P. guajava obtidos por spray drying, com ênfase na influência exercida por diferentes adjuvantes tecnológicos sobre as propriedades físicoquímicas dos extratos padronizados. A primeira etapa do trabalho foi a coleta das folhas de quatro cultivares de Psidium guajava (Paluma, Pedro Sato, Século XXI e Santana da Vargem). A variedade Pedro Sato apresentou os maiores teores de substâncias bioativas correlacionadas com a atividade antioxidante, sendo, portanto selecionada para prosseguimento do trabalho. A solução extrativa foi obtida utilizando o método de extração por maceração dinâmica à temperatura de 56 ºC, por 60 min, utilizando etanol 70% (v/v) como solvente extrator e proporção planta/solvente de 1/10 (m/v). O extrato obtido foi concentrado até teor de sólidos de 10,7 % e acrescido dos adjuvantes de secagem nas proporções de 40 e 80% (base seca). Os adjuvantes empregados neste trabalho (isolados ou em associação) foram a goma arábica (Encapsia), amido modificado (Dry Flo), ?- ciclodextrina (Kleptose), celulose microcristalina (Microcel MC 102), dióxido de silício colloidal (Aerosil 200) e maltodextrina (Mor-Rex 1910). A etapa de secagem foi desenvolvida em um spray dryer de bancada modelo SD-05 da LabPlant, sendo os parâmetros operacionais fixados em: temperatura de entrada do ar de secagem (Tge): 150 ºC, vazão do ar de secagem (Wg): 60 m3/h, vazão de alimentação do extrato (Wsusp): 4 g/min, pressão do ar de atomização (Patm): 1,5 bar e vazão do ar de atomização (Watm): 15 lpm. Os extratos secos obtidos foram caracterizados quanto às características físico-químicas, morfológicas e atividade antioxidante. Foram selecionadas três amostras de extratos secos (maltodextrina:Aerosil, maltodextrina:encapsia:aerosil e ?-ciclodextrina na proporção de 80%) para os estudos de estabilidade e ensaios de atividade antioxidante (DPPH, ABTS, ORAC, FRAP e ensaios em modelos celulares, QLlum) e antimicrobiana (bactérias e fungos). A atividade dos extratos secos de P. guajava sobre o metabolismo oxidativo de neutrófilos humanos estimulados com PMA pelo método da quimioluminescência mostra resultados de inibição da QLlum de forma dependente da concentração e não tóxica sobre os neutrófilos. Os extratos secos foram ativos contra S. aureus e C. glabrata, e inativos contra as bactérias Gram negativas avaliadas. Os resultados deste estudo podem contribuir para o desenvolvimento de novas formas farmacêuticas e para a validação de aplicações clínicas da Psidium guajava, espécie inserida no elenco de espécies vegetais selecionadas para estudos pelo Programa de Pesquisas de Plantas Medicinais e incluída na Relação Nacional de Plantas Medicinais de Interesse ao SUS (RENISUS), justificando a importância da investigação da sua viabilidade tecnológica. / Psidium guajava Linn. (Myrtaceae), popularly known as guava, is widely used in traditional medicine due to its antioxidant, antimicrobial and anti-inflammatory properties. The aim of this work was to standardization and evaluation of the biological activities of spray drying dried extracts of P. guajava, with emphasis on the influence exerted by different carriers on the physicochemical properties of dried extracts. The first stage of the study was the collection of leaves of four cultivars of Psidium guajava (Paluma, Pedro Sato, Century XXI and Santana\'s Vargem). The variety Pedro Sato showed the highest levels of bioactive substances correlated with antioxidant activity, and therefore selected for further work. The extraction solution was obtained using the dynamic maceration method at a temperature of 56 ° C for 60 min using ethanol 70% (v/v) as extractor solvent and plant/solvent ratio of 1/10 (m/v). The extract obtained was concentrated until a solid contents of 10.7% and added with the carriers in proportions of 40 to 80% (dry basis). The carriers used in this study (alone or in blends) were arabic gum (Encapsia), modified starch (Dry Flo), ?-cyclodextrin (Kleptose), microcrystalline cellulose (MC Microcel 102), colloidal silicon dioxide (Aerosil 200) and maltodextrin (Mor-Rex 1910). The drying runs was performed in a bench top spray dryer model SD-05 LabPlant, and the operational parameters set at: inlet temperature of the drying air (Tgi): 150 °C, flow rate of the drying air (Wg): 60 m3/h, feed flow rate of extract (Wsusp): 4 g/min, atomizing air pressure (Patm): 1.5 bar and atomizing air flow rate (Watm): 15 lpm. Spray dried preparations were characterized by physico-chemical, morphological and antioxidant activity. Three samples of dried extracts was selected (maltodextrin: Aerosil, maltodextrin: encapsia: aerosil and ?-cyclodextrin in the proportion of 80%) for stability studies and trials of antioxidant activity (DPPH, ABTS, ORAC, FRAP and assays in cell models, QLlum) and antimicrobial (bacteria and fungi). The activity of dried extracts of P. guajava by cellular test that measured the luminol-enhanced chemiluminescence (CLlum) produced by phorbol myristate acetate (PMA) stimulated neutrophils show results QLlum inhibition of concentration-dependent manner and nontoxic on neutrophils. The dried extracts were active against S. aureus and C. glabrata, and inactive against Gram-negative bacteria evaluated. The results of this study may contribute to the development of novel dosage forms for validation and clinical applications of the Psidium guajava, medicinal specie included in the list of plant species selected for study by the Research Program on Medicinal Plants and included in the National List of Medicinal Plants Interest SUS (RENISUS), justifying the importance of research of its technological feasibility.

No. of bitstreams: 1 TES_EDUARDO_HERZ_BERDICHEVSKI_PARCIAL.pdf: 1111972 bytes, checksum: 207ba6b7db85b282db30b671c8ca89b8 (MD5) Previous issue date: 2017-01-20 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / It has been shown that the use of contrast media in PET/CT (positron emission tomography/ computed tomography) studies is beneficial when compared to an unenhanced CT scan. This is due to the fact that contrast media generates better contrast regarding adjacent structures, allows better characterization of abnormalities, and also allows visualizing alterations that do not present abnormal metabolic behavior. However, contrast agents generate more absorption of CT photons in relation to those of PET potentially giving rise to errors in attenuation correction of PET images. Errors converting the attenuation map from the CT to the PET scan may lead to inaccurate quantification of PET images. The occurrence of SUV (Standardized uptake value) modifications in lesions when PET images are corrected with either contrast-enhanced or unenhanced CT scans has already been studied. Our goal, however, was to study the occurrence of such alterations in relation with lesion size, and distance from the lesion to areas of high contrast concentration, such as high caliber vases and focal areas of the gastrointestinal tract (GIT). Methods: We obtained the SUVmax of 149 lesions, from 26 patients who underwent a PET/CT scan in which images were corrected using both an unenhanced computed tomography (PETCTUE) and a contrast-enhanced computed tomography (PETCTCE). In addition, we measured lesion sizes (smallest and largest diameter, and area) and their distance to large vessels and the GIT. Size measures were not taken when the lesion could not be visualized in the CT image. For lesions in which the distance to high contrast concentration areas was too large or too small, and could not be accurately estimated, the median distance of similar lesions was used to replace the measures. Following the repeated measures principle, we obtained Lin's concordance correlation coefficient and its confidence interval. A Bland-Altman analysis was performed using the absolute difference values and ratio, between PETCTCE and PETCTUE with concordance limits. Results: A total of 149 lesions could be visualized in PET. Eleven of them could not be identified in the CT, and so their measurements were not taken. For 16 lesions, the distance to high contrast concentration areas could not be obtained. The concordance level between the methods, by Lin's concordance correlation coefficient, was 0.99 (CCC: 0.99), and the confidence interval was 95% of 0.98 ? 0.99 (IC95%: 0.98 ? 0.99). The mean absolute difference between the methods was approximately zero and the relative difference was +3.37% (concordance limits of 95% between -2.72 and +2.72, and between -15.73 and +22.48%, respectively). Eighty-two lesions had their larger diameter below 17mm and the other 56 had a larger diameter above or equal to 17mm, with mean percent variation of SUVmax from PETCTCE to PECCTUE of 3.85% and 2.83%, respectively (p=0.54). Sixty-six lesions had a smaller diameter below 17mm and the remaining 72 had a smaller diameter equal to or above 17mm. The mean percent SUVmax variation from PETCTCE to PECCTUE was 2.71%?1,74 and 3.80% ?1,60, respectively (p=0.41). Eighty-two lesions had an area larger than 2.27 cm2 and the other 57 had an area equal to or larger than 2.27 cm2. The mean percent variation of the SUVmax obtained for PETCTCE and PETCTUE was 2.81%?1.64 e 3,83%?1.70, respectively (p=0.48). Sixty-seven lesions were more than 1.82 cm distant from large vessels/ GIT, and 82 were at a less than 1cm distance. The mean SUVmax variation between the methods (PETCTCE versus PETCTUE) was 0.57?1.65% e 4.98?1.61% respectively (p < 0.005). Conclusions: For the totality of studied lesions (149), as well as for the analysis regarding the factors size (non significant p) and distance (significant p), the medium SUVmax variation we identified it not clinically relevant. Thus, both contrast-enhanced and unenhanced PET/CT can be used for attenuation correction. / Nos estudos de PET/CT (tomografia por emiss?o de p?sitrons/ tomografia computadorizada), o uso de material contrastado endovenoso na CT mostra benef?cios diagn?sticos em rela??o a CT n?o contrastada. Isto ocorre pois o material contrastado al?m de gerar maior contraste entre as les?es em rela??o ?s estruturas adjacentes, e melhor caracterizar as anormalidades, tamb?m permite a visualiza??o de altera??es que n?o demonstram comportamento metab?lico anormal. Entretanto, os meios de contraste geram maior absor??o dos f?tons da CT em rela??o aos do PET, e isto tende a gerar erros na corre??o de atenua??o das imagens do PET. Esses erros na convers?o do mapa de atenua??o da CT para o do PET podem levar a inacur?cias na quantifica??o das imagens do PET. A ocorr?ncia de altera??es do SUV das les?es entre as imagens de PET corrigidas para atenua??o com o CT sem contraste e com o CT contrastado j? foi amplamente estudada. Nosso objetivo foi estudar essa ocorr?ncia em fun??o do tamanho das les?es e das dist?ncias entre elas e zonas de maior concentra??o de contraste, como ? o caso de vasos calibrosos e ?reas focais em trato gastrintestinal (TGI). M?todos: Mensuramos o SUVmax de 149 les?es em 26 pacientes cujos exames de PET/CT foram corrigidos tanto utilizando tomografia n?o-contrastada (PETCTSC) quanto tomografia contrastada (PETCTCC). Al?m disso, medimos as dimens?es das les?es (maior e menor di?metro e ?rea) e suas dist?ncias para vasos calibrosos e TGI. Medidas de tamanho n?o foram feitas quando n?o foram visualizadas na CT. Em les?es cujas dist?ncias de ?reas de maior contraste n?o puderam ser feitas com seguran?a por serem muito pr?ximas ou muito grandes, suas medidas foram repostas pela mediana de les?es similares quanto a este aspecto. Seguindo o princ?pio de medidas repetidas, obteve-se o n?vel de concord?ncia dos m?todos atrav?s do coeficiente de correla??o de concord?ncia de Lin e seu respectivo intervalo de confian?a. Realizou-se uma an?lise de Bland-Altman cruzando os valores de diferen?a absoluta e de raz?o entre o PETCTCC versus o PETCTSC com os limites de concord?ncia. Resultados: Das 149 les?es visualiz?veis no PET, 11 n?o demonstraram correspond?ncia na CT, n?o sendo mensuradas suas dimens?es. Dezesseis les?es n?o tiveram calculadas as suas dist?ncias para alguma ?rea de maior concentra??o de contraste e seus valores foram repostos. O n?vel de concord?ncia dos m?todos, pelo coeficiente de correla??o de concord?ncia de Lin, foi de 0.99 (CCC: 0.99) com intervalo de confian?a de 95% de 0.98 ? 0.99 (IC95%: 0.98 ? 0.99). A diferen?a m?dia absoluta entre os m?todos foi de aproximadamente zero e relativa de +3.37% (limites de concord?ncia de 95% entre -2.72 e +2.72 e entre -15.73 e +22.48% respectivamente). Oitenta e duas les?es apresentaram maior di?metro abaixo de 17mm e as outras 56, igual ou acima de 17mm, com diferen?a m?dia percentual dos SUVmax medida nos PETCTCC e PETCTSC igual a 3,85%?1,65 e 2,83%?1,80 respectivamente (p = 0,54). Sessenta e seis les?es apresentaram menor di?metro abaixo do que 17mm e as demais 72, di?metro igual ou acima de 17mm. A diferen?a m?dia percentual dos SUVmax medida nos PETCTCC e PETCTSC foi igual a 2,71%?1,74 e 3,80% ?1,60 respectivamente (p = 0,41). Oitenta e uma les?es apresentaram ?rea menor que 2,27 cm2 e as outras 57, ?rea igual ou maior que 2,27 cm2. A diferen?a m?dia percentual dos SUVmax medida nos PETCTCC e PETCTSC foi igual a 2,81%?1,64 e 3,83%?1,70 respectivamente (p = 0,48). Sessenta e sete les?es tinham dist?ncia de vasos calibrosos/ TGI acima de 1cm, e 82, igual ou menor que 1cm. A diferen?a m?dia percentual entre os m?todos (PETCTCC versus PETCTSC) foi igual a 0,57?1,65% e 4,98?1,61% respectivamente (p < 0,005). Conclus?es: Mesmo para o grupo total de les?es (149) bem como para os grupos de les?es separados em fun??o dos fatores ?tamanho? (p n?o significativo) e ?dist?ncia? (p significativo), a varia??o m?dia do SUVmax visualizada n?o tem relev?ncia cl?nica, tornando intercambi?vel a corre??o do PET pelo CT sem e com contraste.
