Full textAbstract:
Environmental effects of selected monomers, eventually aditives of polymers, will be evaluated by ecotoxicity tests. For this purpose two alternative tests of toxicity: Thamnotoxkit F TM on testing organism Thamnocephalus platyurus and Daphnotoxkit F TM on testing organism Daphnia magna will be used. Two phytotoxicity tests will be also used: Sinapis alba root growth inhibition toxicity test and Allium cepa L root growth inhibition toxicity test. Obtained results enable calculation of value LC50, EC50 and IC50 for tested substances.

Full textAbstract:
Test selection in psychological assessment is guided, both explicitly and implicitly, by how informative tests are with regard to a trait of interest. Most existing formulations of test information are sensitive to subpopulation variation, with the result that test information will vary from sample to sample. Recently, measures of test information have been developed that quantify the potential informativeness of the test. These indices are defined by the properties of the test, as distinct from the properties of the sample or examinee. As of yet, however, measures of potential information have been developed only for unidimensional tests. In practice, psychological tests are often multidimensional. Furthermore, multidimensional tests are often used to estimate one specific trait among many. This study develops measures of potential test information for multidimensional tests, as well as measures of marginal potential test information---test information with regard to one trait within a multidimensional test. In Study 1, the performance of the metrics was tested in data simulated from unidimensional, first-order multidimensional, second-order, and bifactor models. In Study 2, measures of marginal and multidimensional potential test information are applied to a set of neuropsychological data collected as part of Rush University's Memory and Aging Project. In simulated data, marginal and multidimensional potential test information were sensitive to the changing dimensionality of the test. In observed neuropsychological data, five traits were identified. Verbal abilities were most closely correlated with probable dementia. Both indices of marginal potential test information identify the Mini Mental Status Exam as the best measure of that trait. More broadly, greater marginal potential test information calculated with regard to verbal abilities was associated with greater criterion validity. These measures allow for the direct comparison of two multidimensional tests that assess the same trait, facilitating test selection and improving the precision and validity of psychological assessment.

Automated unit tests are essential for the construction of reliable software, but writing them can be tedious. If the goal of test generation is to create a lasting unit test suite (and not just to optimize execution of system tests), it is essential that generated tests can be understood by the developers that will be running them, so that they can tell the difference between real and spurious failures. amock is a system which automatically generates human-readable JUnit regression tests that use mock objects to simulate the behavior of individual objects dynamically observed during a system test execution.

Os pacientes com câncer podem apresentar sintomas pulmonares incapacitantes como dispneia, fadiga e intolerância ao exercício. Considerando que um dos principais tratamentos para essa patologia é a cirurgia, os profissionais devem atentar-se às complicações pós-operatórias (CPO) que estão presentes principalmente nas cirurgias abdominais e torácicas, já que interferem na função muscular e na mecânica respiratória. OBJETIVO: Analisar se a doença oncológica leva a alterações na função cardiorrespiratórias e musculares, avaliar o comportamento da função cardiorrespiratória e da força muscular de pacientes oncológicos submetidos à cirurgia abdominal aberta e identificar os fatores pré-operatórios que podem diferenciar as CPO em pacientes oncológicos submetidos a cirurgia abdominal aberta. METODOLOGIA: Os pacientes foram divididos em dois grupos: grupo experimental (GE) composto por pacientes com diagnóstico de câncer abdominal e grupo controle (GC) com pacientes saudáveis. Na avaliação passaram por anamnese, testes de esforço, teste da função e força pulmonar e teste de força de preensão manual. Considerou-se estatisticamente significante p<0,05. RESULTADOS: Foram avaliados 33 pacientes (19 mulheres) em cada grupo. Quando comparado os pacientes do GC e do GE, observou-se diferença estatística na PImax (%) e na distância percorrida no ISWT (%). Os pacientes que não complicaram no quinto dia de pós-operatório (PO5) ou no trigésimo dia de pós-operatório (PO30) tiveram as variáveis pré-operatórias (PRÉ) comparadas com PO5 ou PO30, respectivamente. Na primeira situação, observou-se que houve diferença estatística em CVF, VEF1, PEF, FEF25-75%, valores reais e (%), VEF1/CVF (%), PImax em valor real e PEmax e ISWT reais e em (%). Já os momentos PRÉ e PO30 sem CPO a diferença foi observada nas variáveis: distância do ISWT real e (%). Quando comparados todos os momentos de pacientes que não complicaram a diferença foi significante em CVF e VEF1 (%), PEF real e distância do ISWT real e (%). E por último foi comparado os momentos PRÉ dos pacientes que não tiveram CPO no PO5 com o PRÉ dos pacientes que tiveram CPO no PO5 e o momento PRÉ dos pacientes sem CPO no PO30 com o momento PRÉ dos pacientes com CPO no PO30. Na primeira situação observou-se diferença estatística em FEF25-75%, real e na distância do ISWT real e (%). Já na segunda situação foi observada diferença estatística em CVF, PFE e FEF25-75% reais e em VEF1 e ISWT reais e (%). CONCLUSÃO: Podemos concluir que a doença oncológica abdominal, assim como a cirurgia abdominal, levam a alterações funcionais cardiorrespiratórias e musculares. E que as variáveis espirométricas, o teste de esforço e a frequência cardíaca foram capazes de diferenciar pacientes que não complicam daqueles que complicam.
Cancer patients may present some disabling pulmonary symptoms such as dyspnea, fatigue and exercise intolerance. Considering that surgery is one of the main treatments for this pathology, professionals should pay attention to postoperative complications (POC) which are present mainly in abdominal and thoracic surgeries, since they interfere in muscle function and respiratory mechanics. OBJECTIVE: To analyze whether oncological disease leads to cardiorespiratory and muscular function disturbance, to evaluate the behavior of cardiorespiratory function and muscular strength in cancer patients submitted to open abdominal surgery and to identify preoperative factors that may differentiate PCO in oncological patients submitted open abdominal surgery. METHODOLOGY: Patients were divided into two groups: experimental group (EG) composed of patients with abdominal cancer and control group (CG) with healthy patients. The evaluation submitted both groups to anamnesis, stress tests, function test and pulmonary force and manual grip strength test. A value for p <0.05 was considered statistically significant. RESULTS: Thirty-three patients (19 women) were evaluated in each group. When comparing CG and EG patients, a statistical difference was observed in the MIP (%) and the distance covered in the ISWT (%). Patients who did not complicate on the fifth postoperative day (PO5) or on the 30th postoperative day (PO30) had the preoperative variables (PRÉ) compared to PO5 or PO30, respectively. In the first situation, it was observed that there was a statistical difference in FVC, FEV1, PEF, FEF(25-75%), real values and (%), FEV1/FVC (%), real MIP and real and (%) MEP, ISWT. In PRE and PO30 moments without PCO, the difference was observed in the variables: distance from the real ISWT and (%). When comparing all the moments of patients who did not complicate the difference was significant in FVC and FEV1 (%), real PEF and ISWT real and (%) distance. Finally, we compared the PRE moments of the patients who did not have POC in the PO5 with the PRE of the patients who had POC in the PO5 and the PRE moments of the patients without POC in the PO30 with the PRÉ moment of the patients with POC in the PO30. In the first situation, we observed a statistical difference in FEF(25-75%), real and in the distance of the real and (%) ISWT. In the second situation, a statistical difference was observed in real FVC, PEF and FEF(25-75%), and in FEV1 and ISWT real and (%). CONCLUSION: We can conclude that abdominal cancer, as well as abdominal surgery, lead to cardiorespiratory and muscular functional changes. And that the spirometric variables, the stress test and the heart rate were able to differentiate patients that do not complicate to those that complicate.

Polymers or their modifiers may become parts of a wide range of products. After the end of life cycle useful parts of the products are recycled but significant parts still become household waste. It´s therefore desirable not only by law on chemicals and chemical products, but also according to the requirements of European directive REACH, to assess the impact not only chemical but also the additives of all products or products themselves in terms of their impact on the environment. For these purposes it serves ecotoxicity tests, which allow prediction of the influence test compounds in the environment. In this diploma thesis were evaluated polypropylene modifiers, which are commercially produced. Use of ecotoxicity tests were evaluated maleic anhydride and itaconic anhydride effects on the environment. Alternative tests have been used for toxicity and namely Thamnotoxkit FTM the organism Thamnocephalus platyurus and Daphnotokit FTM the organism Daphnia magna. The phytotoxicity test groups were selected toxicity tests: Sinapis alba root growth inhibition toxicity test, Allium cepa L root growth inhibition toxicity test and Semi-chronic toxicity test on Lemna minor L. From marine toxicity tests was performed Acute inhibition test of brine shrimps Artemia salina.

Programinės įrangos testavimas yra kritinė viso kūrimo proceso dalis. Kokybe privalo rūpintis ne vien testuotojai. Programuotojai turi naudoti įvairias kokybės užtikrinimo technikas, tokias kaip statinė kodo analizė (kodo peržiūra) ir vienetų testavimas. Kartais programuotojai praleidžia kodo testavimą arba atlieka tik paviršutinį testavimą, nes tai užimą jų laiką. Automatiniai testavimo įrankiai suteikia galimybes testavimo kaštų sumažinimui. Sukurta daug įvairių testavimo atvejų generavimo technikų naudojant specializuotus įrankius. Testavimo atvejų generavimo tikslas yra pasiekti kuo didesnį kodo padengimą ir rasti netikėtas klaidas. Daugumoje atvejų yra neįmanoma pasiekti visišką kodo padengimą, naudojant vien generuotus testavimo atvejus. Reikalingi testavimo atvejai, parašyti žmogaus. Logiška pakartotinai naudoti testus, kuriais buvo ištestuoti panašūs metodai anksčiau. Šiame darbe analizuojama testų pakartotino panaudojimo problema. Siūlomas sprendimas yra paremtas vienetų testų saugojimu ir pakartotinu panaudojimu lyginant testuojamą metodą ir jau ištestuotą, kuris turi išsaugotus vienetų testus. Siūlomas metodas turėtų būti naudojamas kartu su vienetų testų generavimo įrankiais.Software testing is critical part in software development. Not only testers are responsible for software quality. Programmers should use quality assurance techniques as code static analysis (code review) and unit testing. Sometimes developers omit testing their code or perform just superficial testing because unit testing consumes development time. Automated unit testing tools provide the way for reducing of testing costs. There are various techniques for generating test cases by using specialized tools. The goal of generation of tests cases is to achieve higher code coverage and expose unexpected errors. In many cases it is impossible to achieve full code coverage by using only generated test cases. Then manual efforts are needed. It is reasonable to reuse unit tests for method similar to that already tested. This work helps to analyse unit test reusability problem. The approach presented is based on unit test storing and reusing by comparing current testing method and method that has saved tests. This method should be used in combination with particular unit test generation tool.

O objetivo do presente estudo foi estabelecer os critérios de autenticidade científica de validade, reprodutibilidade e a sensibilidade do FSKT10s e do FSKTmult para o taekwondo. O objetivo secundário foi construir uma tabela normativa para classificação do desempenho físico gerado no FSKT. O estudo foi conduzido em seis etapas, contendo amostras de praticantes ou atletas de diferentes níveis competitivos. Visando investigar a validade lógica do FSKT, foi apresentado um questionário para 94 sujeitos que tivessem alguma experiência com a modalidade. O objetivo do questionário foi conhecer a opinião a respeito do entendimento sobre as instruções, viabilidade de aplicação e predominância energética. Os participantes julgaram que o teste é \'fácil\' ou \'muito fácil de entender\', \'viável\' ou \'muito viável\' de aplicar e que ambos os testes medem predominantemente a condição anaeróbia. Quanto maior o grau de instrução, maior a frequência de resposta de que o FSKT10s é predominantemente anaeróbio, enquanto para o FSKTmult a maior frequência de resposta no grupo não graduado mede predominantemente a condição aeróbia e o grupo pós-graduado julgou que o teste mede predominantemente a condição anaeróbia. Na etapa seguinte 13 atletas de taekwondo do sexo masculino participaram em duas sessões experimentais para determinar a validade de critério entre a luta e o FSKT. Não foram encontradas associações entre as variáveis da luta e o FSKT. Não foram identificadas diferenças significantes para o lactato pico após FSKTmult e após luta, mas houve diferença estatística entre a luta e o FSKT10s. O objetivo seguinte foi determinar a validade de constructo. Foram avaliados 153 homens agrupados em não competidores (n= 53), competidores de nível regional/estadual (n= 55) e de nível internacional/nacional (n= 45) e 42 mulheres agrupadas em competidoras de nível regional/estadual (n= 21) e de nível internacional/nacional (n= 21). Houve superioridade dos competidores de nível nacional/internacional em comparação aos não competidores. As competidoras de nível regional/estadual diferiram do grupo de nível nacional/internacional. A etapa seguinte foi conduzida com 14 atletas para determinar a reprodutibilidade relativa e absoluta do FSKT em teste e reteste. Para a reprodutibilidade relativa foram observados valores de CCI entre 0,63 e 0,95. O EPM ficou entre 0,60 e 3,99 enquanto o SWC0,6 ficou entre 0,73 e 4,83 para as diferentes séries do FSKT. Na etapa seguinte foi determinada a sensibilidade do FSKT de 8 atletas após nove semanas de treinamento de taekwondo e de força/potência muscular. Foi observada melhora do desempenho gerado em todas as variáveis analisadas, exceto para o índice de decréscimo de chutes (IDC). Por fim, 115 homens e 70 mulheres praticantes/atletas familiarizados com o FSKT executaram cada teste uma vez. Após análise dos dados foi elaborada a tabela com cinco escalas (classificação, percentil: muito bom, >=95; bom, >75; regular, 25-75; ruim, <25; muito ruim, <=5) para as seguintes variáveis FSKT10S, FSKTmult (séries 1-5) e IDC. A conclusão é que o FSKT pode ser uma ferramenta utilizada por técnicos e treinadores visando medir o desempenho físico. Diferentes critérios de autenticidade científica foram apresentados no presente estudo, o que ajudará a tomar decisões mais confiáveis quando de sua aplicação. Também será possível classificar o desempenho dos praticantes/atletas via tabela normativaThe purpose of the present study was stablishing the authenticity criteria scientific of validity, reliability and the sensibility of FSKT10s and the FSKTmult for taekwondo. The secondary purpose was building a normative table to classify physical performance generated by FSKT. The study was conducted in six parts, content sample of practitioners or athletes in different competitive levels. Aiming to investigate the logical validity of FSKT, was presented a questionnaire for 94 subjects that would have any experience with the modality. The purpose was to know the opinion about the understanding of the instructions, feasibility of application and energetic predominance. The participants judged that the test is \"easy\" or \"very easy\", \"viable\" or \"many viable\" of apply and that both tests measure predominantly the anaerobic condition. The higher the level of education, higher is the response frequency of that the FSKT10s is predominantly anaerobic, while for FSKTmult the higher response frequency in the no-graduate group measure predominantly the aerobic condition and the postgraduate group judge that the test measure predominantly the anaerobic condition. In the next step 13 male taekwondo athletes participated in twice experimental sessions to determine a validity criterion between match and the FSKT. No associations were found between match variables and FSKT. No statistically significant difference were identified for the peak blood lactate concentration post FSKT and match, but there was statistical difference between the match and FSKT10s. the next objective was to determine the construct validity. 153 subjects were evaluated grouped in non-competitors (n= 53), regional/state competitors (n= 55) and national/international competitors (n= 45) and 42 women grouped in regional/state level competitors (n= 21) and international/national level (n= 21). There was a statistically significant difference with the superiority of national/international competitors compared to non-competitors. The regional/state level competitors differed from the national/international level group. The next step was conducted with 14 athletes to determine the relative and absolute reliability of FSKT test-retest. Regarding relative reliability, ICC values between 0.63 and 0.95 were observed. The EPM was between 0.60 and 3.99 while the SWC0.6 was between 0.73 and 4.83 for the different FSKT series. The next step was to determine the sensitivity of the FSKT of 8 athletes after nine weeks of taekwondo and strength training. It was observed an improvement in the performance generated in all variables analyzed except for the kicks decrement index (KDI). Finally, 115 mens and 70 womens practitioners/athletes familiar with the FSKT performed each test once. After analyzing the data, the table was elaborated with five scales (classification: \'Excellent\': >=95th percentile, \'Good\': 75th percentile up to 94th percentile, \'Regular\': 25th percentile up to 74th percentile, \'Poor\': 6th percentile up to 24th percentile, \'Very poor\': <=5th percentile) for the following variables FSKT10S, FSKTmult (series 1-5 and total) and IDC. The conclusion is that the FSKT can be a tool used by coaches and technicians to measure physical performance. Different criteria of scientific authenticity were presented in the present study, which will help to make more reliable decisions. It will also be possible to classify the performance of the practitioners/athletes, based on the classifications of the normative table

Full textAbstract:
Testing has become a wide-spread practice among practitioners. Test cases are written to verify that production code functions as expected and are modified alongside the production code. Over time the quality of the test code can degrade. The test code might contain bugs, or it can accumulate redundant test cases or very similar ones with many redundant parts. The work presented in this dissertation has focused on addressing these issues by characterizing bugs in test code, and proposing a test model to analyze test cases and support test reorganization. To characterize the prevalence and root causes of bugs in the test code, we mine the bug repositories and version control systems of 448 Apache Software Foundation projects. Our results show that around half of all the projects had bugs in their test code; the majority of test bugs are false alarms, i.e., test fails while the production code is correct, while a minority of these bugs result in silent horrors, i.e., test passes while the production code is incorrect; missing and incorrect assertions are the dominant root cause of silent horror bugs; semantic, flaky, environment related bugs are the dominant root cause categories of false alarms. We present a test model for analyzing tests and performing test reorganization tasks in test code. Redundancies increase the maintenance overhead of the test suite and increase the test execution time without increasing the test suite coverage and effectiveness. We propose a technique that uses our test model to reorganize test cases in a way that reduces the redundancy in the test suite. We implement our approach in a tool and evaluate it on four open-source softwares. Our empirical evaluation shows that our approach can reduce the number of redundant test cases up to 85% and the test execution time by up to 2.5% while preserving the test suite’s behaviour.Applied Science, Faculty of

Full textAbstract:
This thesis investigates the possibilities of finding solutions, in order to reduce the total time spent for testing and waiting times for running multiple automated test cases in a test framework. The “Automated Test Framework”, developed by Axis Communications AB, is used to write the functional tests to test both hardware and software of a resource. The functional tests that tests the software is considered in this thesis work. In the current infrastructure, tests are executed sequentially and resources are allocated using First In First Out scheduling algorithm. From the user’s point of view, it is inefficient to wait for many hours to run their tests that take few minutes to execute. The thesis consists of two main parts: (1) identify a plugin that suits the framework and executes the tests in parallel, which reduces the overall execution time of tests and (2) analyze various scheduling algorithms in order to address the resource allocation problem, which arose due to limited resource availability, while the tests were run in parallel. By distributing multiple tests across several resources and executing them in parallel, help in improving the test strategy, thereby reducing the overall execution times of test suites. The case studies were created to emulate the problematic scenarios in the company and sample tests were written that reflect the real tests in the framework. Due to the complexity of the current architecture and the limited resources available for running the test in parallel, a simulator was developed with the identified plugin in a multi-core computer, with each core simulating a resource. Multiple tests were run using the simulator in order to explore, check and assess if the overall execution time of the tests can be reduced. While achieving parallelism in running the automated tests, resource allocation became a problem, since limited resources are available to run parallel tests. In order to address this problem, scheduling algorithms were considered. A prototype was developed to mimic the behaviour of a scheduling plugin and the scheduling algorithms were implemented in the prototype. The set of values were given as input to the prototype and tested with scenarios described under case studies. The results from the prototype are used to analyze the impact caused by various scheduling algorithms on reducing the waiting times of the tests. The combined usage of simulator along with scheduler prototype helped in understanding how to minimize the total time spent for testing and improving the resource allocation process.

Full textAbstract:
The Equivalence Principle is accepted as one of the most fundamental principles in modern Physics. However, theories towards the unification of the four forces typically predict violations of this principle. Testing it at a high sensitivity is expected to make a breakthrough in the current understanding of Physics. A space-based project, STEP (Satellite Test of the Equivalence Principle), aims at testing the principle to the level of 10\(^{−18}\). This corresponds to an improvement of the current limits, established by ground-based experiments, by approximately five orders of magnitudes. To achieve the sensitivity, imperfections in STEP test masses, such as density inhomogeneity and thermal distortion, could be a problem. This thesis presents preliminary work on the verification of STEP test masses. We have measured density inhomogeneities in materials intended to be used as STEP test masses (beryllium and niobium). In addition, we have developed a device to measure differential thermal expansion of samples that cannot be machined, by using a capacitive sensing method. It is shown that the device has a precision of approximately 0.3 % in the differential thermal expansion of beryllium. This device could in principle be applied for the measurements of the real STEP test masses in the final shape. Our analysis based on the results of our measurements and literature survey shows that it is feasible to obtain materials that satisfy STEP requirements.

Full textAbstract:
With the rapid growth in high-stakes testing in recent decades, we have witnessed the phenomenon of large groups of test takers investing increasing amounts of time, resources and energy on test preparation. Their goal is to achieve scores that will enable them to make life defining choices. For many of them, I have discovered that test preparation requires engaging in pressurised practice to achieve a high score rather than engaging in meaningful learning. This research has found the test preparation experience to be a critical experience that impacts on an individual’s life. Until now, we have not known why and how learners prepare to take tests, nor how they construct their identities as test takers, or are constructed by the test preparation. One objective of this study is therefore to examine Korean test takers’ preparation practices for English-speaking proficiency tests from the test takers’ perspectives. The second major objective is to examine how the act of test preparation affects test takers’ identity. The qualitative methodology adopted to investigate these issues included interviews with test takers and observation of test preparation classes in Korea. The data were analysed using coding and thematic categorisation. It was found that test takers tended to study in cram schools, and that preparation was dependent upon instructors and the test for which they were preparing. The study revealed a complex situation with regard to identity construction, related to: (1) personal goal and test preparation choice, (2) English mediated identity in speaking activities and (3) self-conflicts over time. It is suggested that the impact of test preparation on a test taker’s identity may be devaluation of a sense of self. The implications of the study are to raise awareness of the importance of links between test preparation and identity in the field of language testing and teaching.

This diploma thesis deals with a use of algal test in ecotoxicology. A freshwater algae, Desmodesmus subspicatus, was used to asses the ecotoxicity of selected chemical substances. A spectrophotometry method, of VIS spectrum, was used in evaluation of the EC50. A correlation, between a number of algal cells and the wavelength absorbance at 683 nm, has been determined for this purpose. Following chemicals were tested, 2-[2-[(2,6-dichlorophenyl)amino]phenyl]acetic acid, (RS)-2-[4-(2-methylpropyl)phenyl]propanoic acid and N-(4-hydro-xyphenyl)acetamide. An EC50 value was determined for all these substances and also their ecotoxicity has been evaluated.

This thesis deals with ecotoxicity tests of selected substances used in agriculture and horticulture. It is focused on the determination of acute and chronic toxicity of selected herbicides. These herbicides are sold commercially, specifically Finalsan (active substance is nonanoic acid), the product of Neudorff GmbH KG company, and Dominator (active substance is glyphosate, isopropylamine salt) by Dow AgroSciences Ltd. Next tested substances are potassium nitrate and sodium nitrate - common agricultural fertilizers. Potassium dichromate was also tested. Potassium dichromate is very toxic for aquatic environment and it is used as the standard in acute tests. Tests were carried out in terms of effects on aquatic systems, due to very good solubility in water of selected substances. The tests were performed on the organism Daphnia magna.

Syftet med detta examensarbete är att undersöka lärares uppfattningar om det nationella provet i engelska, samt hur dessa lärare arbetar med provet för att kunna hjälpa eleverna att nå sina kursmål. Undersökningsmetoden är kvalitativ då vi intervjuat fyra lärare i engelska på en högstadieskola. Intervjufrågorna har innefattat allt från hur lärare arbetar med det nationella provet och hur de ser på provet, till hur målen med det nationella provet uppfylls. Resultatet av undersökningen är att det nationella provet underlättar lärarnas arbete. Lärarna anser även att provet fungerar som ett bra stöd då de ska betygsätta eleverna. Dock visar denna undersökning att förberedelserna till det nationella provet främst gagnar svagare elever.The purpose of this dissertation is to investigate how teachers perceive and work with the national tests in order to help students meet the goals of the course. Furthermore, due to our future careers as teachers, we want to gain more insight into the role national tests play in English. This is a qualitative study based on formal in-depth interviews that can provide a good understanding of the subject and of the informants’ views. As the teachers at secondary school work with national tests yearly they were best suited as interviewees in this investigation. Four interviews were carried out with teachers and they lasted approximately 40 minutes each.The interviews touched on a variety of questions ranging from how the teachers work with the national test and how they look upon the test, to how the purposes stipulated by Skolverket regarding the national test are fulfilled. The outcome of the interviews is that the national test in general facilitates more than complicates teachers’ work. The test serves as a good support when assessing and grading the students since it can confirm the teachers’ assessment of the students’ capability. However, this study also shows that the preparation methods used before the national test benefit weaker learners more than stronger ones.

Full textAbstract:
Semiconductor industry goals for the quality of shipped products continue to get higher to satisfy customer requirements. Higher quality of shipped electronic devices can only be obtained by thorough tests of the manufactured components. Scan chains are universally used in large industrial designs in order to cost effectively test manufactured electronic devices. They contain nearly half of the logic transistors in large industrial designs. Yet, faults in the scan cells are not directly targeted by the existing tests. The main objective of this thesis is to investigate the detectability of the faults internal to scan cells.
In this thesis, we analyze the detection of line stuck-at, transistor stuck-on, resistive opens and bridging faults in scan cells. Both synchronous and asynchronous scan cells are considered. We define the notion of half-speed flush test and demonstrate that such new tests increase coverage of internal faults in scan cells. A new set of flush tests is proposed and such tests are applied at higher temperatures to detect scan cell internal opens with a wider range of resistances. We also propose new scan based tests to further increase the coverage of those opens. The proposed tests are shown to achieve the maximum possible coverage of opens in transistors internal to scan cells. For an asynchronous scan cell considered, two new flush tests are added to cover the faults that are not detected by the tests for synchronous scan cells. An analysis of detection of a set of scan cell internal bridging faults is described. Both zero-resistance and nonzero-resistance bridging fault models are considered. We show that the detection of some zero-resistance non-feedback bridging faults requires two-pattern tests. We classify the undetectable faults based on the reasons for their undetectability.
We also propose an enhanced logic BIST architecture that accomplishes the new flush tests we propose to detect scan cell internal opens.
The effectiveness of these new methods to detect scan cell internal faults is demonstrated by experimental results using some standard scan cells from a large industrial design.

Grandes saltos tecnológicos viabilizaram a integração de circuitos digitais de alta complexidade, com centenas de pinos e milhões de transistores. Sistematicamente, dispositivos eletromecânicos estão sendo substituídos por Circuitos Integrados (CIs) que contêm sistemas inteiros, ampliando o uso generalizada da eletrônica. Com o aumento da complexidade e quantidade de CIs produzidos, a tarefa de detectar de forma rápida e eficiente aqueles chips com problemas assumiu grande importância. Como a Testabilidade [McClu 86] de um CI afeta sua qualidade, um circuito que não é completamente testável, para um determinado modelo de falha, tem menos valor que outro inteiramente testável [De Mi 94]. Em estudos sobre confiabilidade, desempenho, custos e Testabilidade de circuitos VLSI verificou-se que o custo associado ao processo de testes de circuitos VLSI estava praticamente estabilizado, enquanto outros componentes do preço final do chip caíam. Por estas razões, a Testabilidade foi incorporada ao projeto desde suas concepções iniciais, apresentando geralmente resultados com menor Sobreárea e mínimo impacto no desempenho, quando comparado a CIs produzidos sem considerações relacionadas a testes. Uma técnica de teste que dispensa o uso de Equipamento Automático de Teste, conhecida como Autoteste Incorporado (em inglês, Built-In Self-Test BIST), consiste em adaptar partes do próprio CI para gerar Vetores de Teste, comprimir e analisar os resultados. A técnica BIST tem sido empregada com sucesso em ambientes de projeto de Síntese de Alto Nível (High Level Synthesis, HLS), que tende a reduzir o tempo de projeto de um ASIC, auxiliando a determinação da arquitetura RTL [Stru et al. 99]. Nesta dissertação, considera-se uma forma específica de BIST, o structural off-line BIST [Abr et al. 90], em que o Autoteste se dá quando o CI digital é retirado de sua operação normal e colocado em modo teste, para que um Plano de Teste para Unidades Funcionais seja executado (na fase de manufatura e/ou de serviço em campo). O Plano de Teste, baseado em uma descrição estrutural do CI, é gerado por um algoritmo concebido para detectar os registradores que devem ser reconfigurados em Geradores de Padrões de Teste (em inglês, Test Pattern Generators, TPGs) e Analisadores de Assinatura (Signature Analyzers, SAs). O critério de seleção dos registradores baseia-se numa Função Custo, que avalia globalmente o grau de compartilhamento de cada registrador candidato, e a contribuição que a sua eventual escolha causaria no tempo final de teste. Os Registradores de Teste, reconfigurados em Autômatos Celulares (Cellular Automata, CAs), devem operar segundo um Rule Number, neste caso, Regra 90 ou 150. A tarefa do Autoteste paralelo é dividida em duas etapas: na primeira, a cada uma das Unidades Funcionais é associado o melhor momento possível para início de sua sessão de teste, resultando na construção gradativa de uma Matriz de Estado de Teste, e na segunda, com a Matriz de Estado de Teste já totalmente definida, é feita uma análise global para minimizar o número de candidatos a registrador de teste. O resultado final é um Plano de Teste Otimizado definindo as regras dos TPGs (TPG90 e/ou TPG150), o custo em termos de Sobreárea, o início da geração dos Vetores de Teste, sua duração e a Cobertura de Falha mínima.Great technological developments have made possible the integration of digital circuits of high complexity, with hundreds of pins and million of transistors. Electromechanical devices are being systematically substituted for Integrated Circuits (ICs) that contain complete systems, extending the generalized use of electronics. With the increasing complexity and amount of ICs, the task of detecting faulty chips in a fast and efficient way has assumed great importance. As testability [McClu 86] affects the quality of an IC, a circuit that is not fully testable for one determined fault model has less value than another which is entirely testable [De Mi 94]. It was verified in studies on reliability, performance, costs and testability of VLSI circuits that the cost associated with tests was practically stabilized, while other components of the final price fell. For these reasons, testability was incorporated in the design since its initial conception, producing generally minor area overhead and minimum impact on the performance, when compared to ICs produced without test considerations. One test technique that eliminates de needs for use of Automatic Test Equipment, known as BIST - Built-In Self-Test, consists of adapting parts of the IC to generate Test Vectors, compress and analyze the results. The BIST technique has been used successfully in design of HLS - High Level Synthesis - environments, which tends to reduce the ASICs design time, easing the task of determining the RTL architecture [Stru et al. 99]. In this dissertation a specific form of BIST, the structural off-line BIST [Abr et al. 90], is considered. To start the self-test it is necessary to halt the normal operation of the digital IC and put it in test mode, so that a Test Plan for Functional Units is executed (in the phase of manufacture and/or in the field). The Test Plan based on the structure of the IC is generated by an algorithm conceived to detect the registers which will be reconfigured in TPGs - Test Pattern Generators, and SAs - Signature Analyzers. The criterion for selection of the registers is based on a Cost Function, which globally evaluates the degree of sharing of each register candidate, and the contribution that its eventual choice would cause in the final test time. The Test Registers reconfigured in CAs Cellular Automata - must operate according to a Rule Number, in this case Rule 90 or 150. The task of the parallel self-test is divided into two stages: in the first one, to each Functional Unit is associated the best possible moment for its test session beginning, resulting in the gradual construction of a Test Status Matrix, and in the second, with the Test Status Matrix completely defined, a global analysis is made to minimize the number of register candidates. The final result is an Optimized Test Plan, which defines the rules of the TPGs (TPG90 and/or TPG150), the area overhead cost, the beginning of the Test Vector Generation, its duration and the minimum Fault Coverage.

A presente pesquisa teve o objetivo de atualizar os parâmetros psicométricos do Psicodiagnóstico Miocinético PMK. Foi estudada uma amostra composta por 210 sujeitos adultos, todos destros, divididos em quatro grupos, um com 50 mulheres depressivas, um com 50 pacientes esquizofrênicos (35 homens e 15 mulheres), um com 50 reincidentes do sexo masculino do Sistema Prisional do Estado de São Paulo, que cometeram crimes de furto e/ou roubo e um grupo de controle, com 60 participantes (29 mulheres e 31 homens). Os instrumentos utilizados foram a entrevista clínica estruturada para o DSM-IV-TR, também conhecida como SCID-NP, com a finalidade de observar a presença de morbidades entre os presos e o grupo controle e de comorbidades entre os depressivos e esquizofrênicos, o Teste Palográfico, usado como critério no estudo de validade, e o PMK. A precisão foi obtida por meio do teste-reteste, somente com os protocolos da amostra controle e a validade, pelo método de grupos contrastantes e pelo método de validade simultânea. Para a precisão, foi calculado o coeficiente de correlação de Pearson e também utilizado o teste t para determinar se existiam diferenças entre os resultados das duas aplicações. Para os grupos contrastantes foi utilizada a ANOVA de um fator e o teste Post hoc de Tukey, com a finalidade de observar possíveis diferenças significativas das medidas do PMK entre os grupos. Nesta análise, os resultados foram comparados de acordo com o gênero dos participantes. Para a validade simultânea, os dados do Tônus Vital e da Agressividade do PMK e os da Produtividade, Direção das Linhas e Ganchos do Palográfico foram transformados em nota z e correlacionados por meio do coeficiente de correlação de Pearson, primeiramente com a amostra total e posteriormente com o grupo de depressivas e com o grupo de presos, separadamente. Os resultados do estudo de precisão indicaram que boa parte das medidas e dos traçados do PMK apresentou satisfatória estabilidade temporal, não sendo encontrada nenhuma diferença significativa entre teste e reteste. Ao todo, 64% das correlações foram superiores a 0,60, e as maiores médias das correlações foram para o Tônus Vital, a Agressividade e a Dimensão Tensional. As obtidas para o Predomínio Tensional foram as que apresentaram valores mais baixos, embora as correlações entre as aplicações tenham sido, todas, moderadas. Os resultados da validade entre grupos contrastantes demonstraram que, entre as mulheres, as diferenças significativas ocorreram, principalmente, no Tônus Vital, na Emotividade e na Dimensão Tensional. Entre os homens, na Agressividade, na Emotividade (com e sem sinal no DS) e na Dimensão Tensional. Os resultados da validade simultânea revelaram que as maiores correlações ocorreram entre as medidas da Agressividade do PMK com os Ganchos à direita do Palográfico. As correlações obtidas para o Tônus Vital também foram, na maior parte dos casos, significativas. A partir desses resultados, considerou-se que o PMK possui parâmetros científicos que permitem afirmar que ele é um teste preciso e válido para discriminar quadros clínicos de não clínicosThe present research had the purpose to update psychometric parameters of the Myokinetic Psychodiagnosis PMK. Participated a sample of 210 adult subjects, all right handed, divided into four groups, the first composed by 50 depressed women, the second by 50 schizophrenic patients (35 men and 15 women), the third by 50 male prisoners from the Prison System of the São Paulo State who had rescinded thefts and/or steals crimes, and a control group with 60 participants (29 women and 31 men). The instruments used were the Structured Clinical Interview for the DSM-IV-TR, also known as SCID-NP, in order to observe the presence of morbidity among prisoners and the control group and the co morbidity among depressed and schizophrenics. The Test Palográfico, was used as the validity criterion of the PMK test. The reliability was obtained by test-retest, restricted to the control sample and validity by the method of contrasting groups and the simultaneous validity. For the reliability was calculated the Pearson correlation coefficient and also the t test was used to verify if there were differences between the test-retest results. To evaluate the validity by contrasting groups it was used the one-way ANOVA and Pos hoc Tukey test, in order to determinate possible differences of PMK measures between groups. For simultaneous validity, data from PMK Vital Tonus and Aggressiveness and Productivity, Direction Lines and Hooks of Palográfico were transformed in z scores and then correlated by Pearson correlation coefficient, using data from the total sample and from the depressive group and the prisoner group independently. Results of the reliability study indicated that most of measures of PMK had a satisfactory temporal stability and no significant difference between test and retest means was found. Altogether, 64% of correlations were above 0.60 and higher means of correlations were for the Vital Tonus, Aggressiveness and Tensional Dimension. Correlations for Tensional Predominance showed the lowest values, although they can be considered moderate. Results of contrasting groups showed that, among women, significant differences were observed mainly in Vital Tonus, Emotionality and Tensional Dimension, and among men in Aggressiveness, Emotionality (with an without DS signal) and Tensional Dimension. The concurrent validity showed that significant correlations occurred mainly between PMK Aggressiveness measures and Palográfico Hooks at right. Vital Tonus correlations were in most cases significant. These results indicate that the PMK Test presents scientific parameters that allow to confirm that its a reliable and valid test to discriminate clinical cases from those non-clinical

INTRODUÇÃO: Linfangioleiomiomatose (LAM) é uma doença rara, caracterizada pela proliferação de células musculares lisas atípicas ao redor de vias aéreas, vasos sanguíneos e linfáticos, com formação de cistos pulmonares difusos. Na prova de função pulmonar (PFP), a doença se caracteriza por padrão obstrutivo, aprisionamento aéreo e redução da capacidade de difusão do monóxido de carbono (DLCO), podendo haver resposta positiva ao teste de broncodilatação. No teste de exercício cardiopulmonar (TECP), a menor tolerância ao esforço é frequente e secundária a múltiplas causas, com maior destaque para a limitação ventilatória. Entretanto, nem todos os fatores potencialmente limitantes foram investigados. Os principais objetivos do estudo foram avaliar a prevalência e os preditores de hiperinsuflação dinâmica (HD) em pacientes com LAM, em comparação a mulheres saudáveis (controles), investigando-se adicionalmente a resposta ao broncodilatador. METODOLOGIA: Realizou-se avaliação transversal de 42 pacientes com LAM utilizando-se questionário de qualidade de vida, PFP e TECP incremental no ciclo-ergômetro, com medida seriada da capacidade inspiratória (CI) para definir HD, comparando-se aos controles. As pacientes foram ainda submetidas ao teste de caminhada de seis minutos (TC6M). A seguir, elas foram incluídas em uma avaliação randomizada, cruzada, placebocontrolada, duplo-cega (salbutamol inalatório vs. placebo). PFP e TECP com carga constante, com medida seriada da CI, foram realizadas após cada intervenção. RESULTADOS: Comparando-se aos controles, as pacientes com LAM apresentaram pior qualidade de vida, principalmente nos domínios físico e emocional, e padrão obstrutivo, aprisionamento aéreo e redução da DLCO na PFP. As pacientes demonstraram ainda menor capacidade de exercício, associada com limitação ventilatória, dispneia mais intensa e maior dessaturação no esforço. HD ocorreu em 55% das pacientes, mesmo naquelas com alteração funcional leve, e não foi observada nos controles, correlacionando-se com obstrução ao fluxo aéreo, aprisionamento aéreo, comprometimento da DLCO e dispneia. Em comparação ao subgrupo que não teve HD (subgrupo não HD), as pacientes que desenvolveram HD (subgrupo HD) tinham maior tempo de diagnóstico, caracterizando-se por obstrução ao fluxo aéreo, aprisionamento aéreo e DLCO reduzida. Apesar da capacidade de exercício semelhante, observou-se que o subgrupo HD apresentou limitação ventilatória, além de maior dessaturação e maior grau de dispneia no TECP e no TC6M. Não houve redução da HD ou aumento do tempo de exercício após utilização de salbutamol inalatório, mesmo no subgrupo HD. CONCLUSÕES: HD é frequente nas pacientes com LAM, mesmo naquelas com alteração leve na espirometria, associando-se com duração e gravidade da doença, maior grau de dispneia e menor saturação de oxigênio. Limitação ventilatória e alteração da troca gasosa são importantes fatores para interrupção do exercício em pacientes com LAM. HD também se associa com maior dessaturação e dispneia mais intensa no TC6M. Salbutamol inalatório não reduz HD ou aumenta duração do exercício no ciclo-ergômetro.BACKGROUND: Lymphangioleiomyomatosis (LAM) is a rare disease that is characterized by the proliferation of atypical smooth muscle cells around the airways, blood vessels and lymphatics, with diffuse pulmonary cyst formation. An obstructive pattern, with air trapping, and a reduction in the diffusion capacity of the lungs for carbon monoxide (DLCO) are found in pulmonary function tests (PFTs), and there may be a positive response to the bronchodilation test. In the cardiopulmonary exercise testing (CPET), a lower exercise tolerance is frequent, secondary to multiple causes, with a greater emphasis on ventilatory limitation. However, not all potentially exercise limiting factors were evaluated. The aims of this study were to evaluate the prevalence and predictors of dynamic hyperinflation (DH) in patients with LAM in comparison with healthy women. The response to bronchodilator was also evaluated. METHODS: A cross-sectional study with 42 patients with LAM was conducted, with evaluation of a quality of life questionnaire, PFTs and a ramp CPET on cycle, with serial measurements of inspiratory capacity (IC) to establish DH. Data were compared with the healthy control subjects. The patients also performed the six-minute walk test (6MWT). Then, the patients were included in a randomized, placebo-controlled, doubleblind, crossover evaluation (inhaled salbutamol vs. placebo). After each intervention, they performed PFTs and endurance CPET with serial measurements of IC. RESULTS: In comparison with the healthy individuals, the patients with LAM experienced an impaired quality of life, mainly in the physical and emotional domains. They also had obstructive pattern, air trapping and lower DLCO in the PFTs. LAM was associated with diminished exercise performance, in association with ventilatory limitation, greater dyspnea intensity and exercise desaturation. DH occurred at a higher prevalence (55%) in patients with LAM, even in those with mild spirometric abnormalities, compared with no occurrence in the normal subjects. DH correlated with airflow obstruction, air trapping, DLCO impairment and dyspnea. The patients who developed DH (DH subgroup) had a longer duration since diagnosis and were characterized by airflow obstruction, air trapping and reduced DLCO, compared with those who did not have DH (non-DH subgroup). Although there was no difference in the exercise performance, DH subgroup had ventilatory limitation, with a higher desaturation and greater dyspnea intensity in the CPET and in the 6MWT. There was no reduction of DH or increase in exercise duration after use of inhaled salbutamol, even in the DH subgroup. CONCLUSIONS: DH is frequent in patients with LAM, even in those with mild spirometric abnormalities, and it is associated with the duration since diagnosis, the severity of disease, augmented dyspnea and lower oxygen saturation. Ventilatory limitation and gas exchange impairment are important reasons for exercise cessation in patients with LAM. DH is also associated with desaturation and greater dyspnea intensity in the 6MWT. Inhaled salbutamol does not reduce DH or improve exercise duration on cycle.

Full textAbstract:
This master thesis was performed at the personal genomics company DNA-Guide Europa AB. The goal was to create DNA tests for drug response and to update the already existing DNA test for autosomal ancestry. The DNA tests for drug response: The objective of this part of the master thesis was to create individual DNA test for response to each drug within different groups of medicines. The tests were meant to interest private customers. DNA-Guide uses a microarray technique for the DNA-analysis and this delimited the choice of SNPs. Inserts, deletions, repeats and copies of a whole gene can be difficult to implement on the microarray chip. The SNPs and studies used as a base for the tests had to fulfil several criteria. The studies must be large enough to prove that the association between the genotype and the response to the drug is valid among Europeans, since it’s the clientele of the company. The found association must also be strong enough to be of interest for a DNA test at DNA-Guide. If the SNPs could be implemented on the microarray chip a customer report was created about the possible results. The report had the same structure and design as those for the existing DNA tests at DNA-Guide. The work resulted in DNA tests and reports for medicines within the seven groups of medicines; anticoagulants, medicine against high cholesterol, blood pressure lowering medicine, asthma inhalers, antidepressants, birth-control pills and antiretroviral drugs. The DNA test for autosomal ancestry: The purpose of the update was to enhance to customers understanding of their results and the construction of the test. The update resulted in a description of how the used algorithm processes the results (from the DNA analysis) and a guide to interpret the results of the test. Conclusions: Both the DNA tests for drug response and the updated DNA test for autosomal ancestry can add value for the customers at DNA-Guide. The DNA tests for drug response can offer an explanation to why a medicine does not have an effect or reveal if the customer has higher risk of adverse effects. Even though recommendations for dosage or treatment could not be provided in almost all of the created DNA tests, being aware of the higher risk can be the first step to avoid adverse effects. The update of the DNA test report for autosomal ancestry resulted in a better description of the algorithm and limitations of the test, which can enhance the customers’ understanding of their results.

Full textAbstract:
Introduced in 1986, the Stanford-Binet Intelligence Scale: Fourth Edition differs radically from its predecessors. Because of the adaptive testing format and the limited number of items given to each subject, it is especially important that consecutive levels in each of the tests increase in difficulty. The purpose of this study was to investigate the progression of difficulty among items in the Fourth Edition.Three hundred sixty-four subjects f iii Indiana who ranged in age from 3 years, 0 months to 23 years, 4 months were administered the Fourth Edition. The study was limited to those subjects earning a Composite SAS Score at or above 68.Data were presented to indicate trends in the difficulty of each item as well as in the difficulty of each level in the Fourth Edition. Three research questions were answered. 1.) Are the items at each level equally difficult? 2.) Are the levels in each test arranged so that the level with the least difficult items is first followed by levels with more and more difficult items? 3.) In each test is an item easier for subjects who have entered at a higher level than it is for subjects who have entered at a lower level?The results supported the hypotheses, confirming that the Fourth Edition is a solidly constructed test in terms of item difficulty levels. Most item pairs within a level were found to be approximately equal in difficulty. Nearly all of the levels in each test were followed by increasingly more difficult levels. And each item was found to be more difficult for subjects entering at a lower entry level than for those entering at a higher entry level with very few exceptions. For these few discrepancies found, there was no reason to believe that these were caused by anything other than chance.Department of Educational Psychology

This research focused on the cultural bias in the items the California Achievement Tests (CAT). Performance variability was examined across all individual items of the CAT for the third graders from four ethnic groups. A sample of 1600 third grade children was randomly selected from population of children attending various elementary schools in the state of Arizona. Four hundred subjects within each ethnic group were matched for sex, ethnicity, and grade level. A two-factor (items scores and ethnicity) ANOVA procedure was used to examine the interaction between the item performances and ethnicity for groups of Anglo and Black, Hispanic, and American Indian on all individual test items of the eight subtest of the CAT. An examination of obtained findings revealed that a total of 31 items were found to be as culturally biased against Hispanic, Blacks, and Native-American children. Of these items, thirty were biased toward American Indians, six items were biased toward Hispanics, and four items were biased toward Blacks. Some items were biased toward more than one ethnic group. Twenty-eight items identified as biased belonged to five of the six language subtests and three items are part of one of the two mathematics subtests. It should be noted that even though most of the items (98%) did not reveal any statistical evidence of bias, there were only four items (1.9%) on which minority group children performed higher than did the Anglo children. The overall direction of the findings would seem to suggest that most of the content of the CAT is free from cultural bias.

Dentre outras questões em saúde pública, o tabagismo e a depressão se constituem em situações que ocupam os profissionais de saúde que buscam elaborar medidas preventivas auxiliares no tratamento destas. O tempo de duração, as recaídas e os problemas, físicos e mentais, que sofrem as pessoas, portadoras destes transtornos mentais, constituem um grande desafio no tratamento dos mesmos. Buscar instrumentos de avaliação psicológica que auxiliem neste processo é o principal objetivo. Este trabalho verificou indicadores de depressão em pessoas portadoras de dependência de nicotina (tabagistas), por meio do Teste de Bender e do Método de Rorschach, que podem mensurar traços do funcionamento da personalidade, contribuindo para o entendimento destas características de personalidade, auxiliando na compreensão dos processos psíquicos do indivíduo tabagista, informações que podem auxiliar nos processos preventivos. Os participantes são tabagistas e não tabagistas que estavam cursando algum curso superior e sem histórico de tratamento de depressão ou outro transtorno mental. A coleta de dados foi realizada individualmente com cada um dos participantes (n=60). Os instrumentos utilizados foram entrevista preliminar; a Adaptação Hutt do Teste de Bender e o Método de Rorschach. Os principais resultados se referem ao Teste de Bender e ao Método de Rorschach pelo Sistema Compreensivo de Exner. No Bender são relevantes os dados relativos à análise configuracional da Depressão da Escala de Psicopatologia; no Rorschach são ressaltados os itens que compõe o Índice de Depressão. Concluiu-se que o Teste de Bender, com a escala de avaliação de aspectos psicopatológicos, e o Método de Rorschach, no Sistema Compreensivo, podem auxiliar nos trabalhos preventivos, trazendo indicadores do funcionamento psíquico do indivíduo tabagista. Por outro lado, também se verificou a necessidade de aprofundamento dos estudos nesta área, ampliando o número de participantes e realizando estudos longitudinaisAmong other public health issues, smoking and depression are situations that worry health professionals. Thus, they try to take measures to provide against them and help in their treatment. The duration, relapses, and the mental and physical problems of people who present these mental disorders go through present a big challenge to the treatment. Searching for ways to evaluate psychologically and, therefore, help in this process is the main goal. This work detected depression symptoms in people addicted to nicotine (tobacco users) by using the Bender Test and the Rorschach Method, which can measure aspects of the personality, contributing to the understanding of these personality traits. It can help us understand the psychological processes of the tobacco users, helping in the prevention processes. The participants were smokers and non smokers; they were college students and had never undergone any depression or mental disorder treatment. The data collection was carried out individually with each one of the participants (n=60). Preliminary interviews, the Hutt Adaptation of the Bender Test, and the Rorschach Method, Comprehensive System were used. The main results refer to the Bender Test and the Rorschach Method. In the Bender Test, the data related to the configuration in the analysis of depression from the psychopathology; in the Rorschach Method the items that comprise the Depression Index. It was concluded that the Bender Test, with the scale of evaluation of psychopathologic aspects, and the Rorschach Method can help in the prevention procedures, showing how the psychological functioning of smokers work. On the other hand, it became clear that a deep study in this area is necessary, increasing the number of participants and carrying out longitudinal studies

Full textAbstract:
The Peabody Picture Vocabulary Test-Revised (PPVT-R) and Slosson Intelligence Test (SIT) were designed, at least in part, to provide a quick estimate of scores which might be obtained on the Stanford-Binet Intelligence Scale, Form L -M, without requiring extensive technical training by the examiner. Both the PPVT-R and SIT are frequently used as screening instruments to identify children for possible placement in special education programs, remedial reading groups, speech and language therapy, gifted programs, or "tracks." This study investigated the value of the PPVT-R and SIT as screening instruments for the Fourth Edition Stanford-Binet.Fifty students, grades kindergarten through fifth, were randomly selected to participate in the study. All subjects were involved in regular education at least part-time. Subjects were administered the PPVT R, SIT, and Fourth Edition Binet by a single licensed school psychologist. The administration order of the instruments was randomized. Participants were tested on consecutive school days (10) until all subjects had been administered the three instruments.Correlation coefficients were determined for the Standard Score of the PPVT-R and each Standard Age Score of the Binet (four area scores and one total test score), as well as for the SIT IQ score and each Standard Age Score of the Binet. All correlations were positive and significant beyond the p<.Ol level except between the PPVT-R and Binet Quantitative Reasoning.Analyses of Variance were used to determine mean differences of scores obtained on the three instruments. Significant differences (p<.05) were found between scores on the PPVT-R and Abstract/Visual Reasoning, SIT and Verbal Reasoning, SIT and Short-Term Memory, SIT and Abstract/Visual Reasoning, and SIT and Total Test Composite.Results indicated that, in general, the SIT is a better predictor of Fourth Edition Binet scores than the PPVT R, however frequently yielded significantly different scores. It was concluded that neither the PPVT R nor SIT should be used as a substitute for more comprehensive measures of intellectual functioning, and caution should be used when interpreting their results. Much more research is needed to clarify the diagnostic value of the Fourth Edition Stanford-Binet as a psychometric instrument.

Full textAbstract:
Eighty-eight (N = 88) non-brain-injured adults were tested with one of two versions of the Booklet Category Test (BCT). Forty-four (N = 44) individuals were tested with the standard version of the BCT, and forty-four (N = 44) were tested with a revised BCT in which between-subtest cueing was removed, called the Noncued Category Test (NCT). The results of this study indicate that removal of cueing instructions changes the Category test significantly. Subjects administered the NCT scored significantly more errors than those who were administered the standard Category test. While BCT scores correlated significantly with nonverbal intelligence scores, NCT scores did not. However, the difference in these correlations was not significant, indicating that the intelligence aspect measured in the two versions is not different. Neither the BCT nor the NCT correlated significantly with the Wisconsin Card Sort, Word Fluency, Stroop, or Trail Making Test. It is recommended that the NCT be administered to circumscribed clinical populations in order to best utilize present findings.

Full textAbstract:
The purpose of the study was to investigate the validity of the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE) area and composite scores and Sattler's SB:FE factor scores as predictors of school performance on the Woodcock-Johnson Tests of Achievement (WJTA).The subjects were 80 Caucasian third grade students enrolled in regular education in a rural and small town school district in northeastern Indiana. The SB:FE and WJTA were administered to all students.Two canonical analyses were conducted to test the overall relationships between sets of SB:FE predictor variables and the set of WJTA criterion variables. Results indicated that the SB:FE area scores and Sattler's SB:FE factor scores were valid predictors of academic achievement at a general level.To clarify the results of the canonical analyses, series of multiple regression analyses were conducted. Results of multiple regression with SB:FE area and composite scores indicated that the best single predictor of all WJTA scores was the SB:FE Test Composite Score. No other SB:FE variable provided a significant contribution to the regression equation for reading, math, and written language achievement over that offered by the Test Composite Score.Multiple regression analyses were also employed with Sattler's SB:FE factor scores and the WJTA scores. The optimal predictor composite for reading included the Verbal Comprehension and Memory factor scores. To predict math, the best predictor composite consisted of the Nonverbal Reasoning/Visualization and Verbal Comprehension factor scores. The optimal predictor composite for written language included the Nonverbal Reasoning/Visualization and Memory factor scores.Results of the regression analyses indicated that, without exception, the predictor composites composed of the SB:FE area and composite scores were superior in their prediction of school performance to the predictor composites developed from Sattler's SB:FE factor scores.The regression equation containing the SB:FE Test Composite Score alone was determined to be the preferred approach for predicting WJTA scores. Use of the Test Composite Score sacrifices only a minimal degree of accuracy in the prediction of achievement and requires no additional effort to compute.Department of Educational Psychology

Ergospirometric test, gold standard evaluation of cardiorespiratory fitness, is not an economically accessible and easy to apply test, especially for patients with Cerebral Vascular Accident (CVA) sequelae. Thus, field tests such as the Shuttle Walk Test Incremental (SWTI) may be another option for evaluation of cardiorespiratory function. Objective: compare the ventilatory, metabolic and cardiovascular responses obtained by the SWT and ergospirometric test, in hemiparetics due to stroke. Secondary objective was compared with the results of the ventilation evaluations with mild, moderate, marked and severe motor impairment of hemiparetic patients. Methodology: transversal study, with 20 hemiparetic subjects, motor impairment (05 mild, 04 moderate, 05 severe, 06 severe), 58 ± 10 years old, 08 women and 12 men. The VO2maximum (VO2), ventilatory (VE), desaturation, heart rate (HR) and blood pressure (BP), during the SWTI and ergospirometry, were evaluated in two days, 48h interval. Results: SpO2 was similar (97 [96-98]; 97 [94-97]) respectively in SWT and ergospirometry. VO2Pico metabolic variables (18 ± 4, 24 ± 4), cardiac FCPic (101 ± 17, 115 ± 15), systolic BP (140 [140-147], 160 [140-160]) and diastolic (2 ± 1, 3 ± 1), fatigue (2 [1-4], 4 [2-6]) and distance traveled (248 ± 154, 409 ± 1) 216). Comparison between groups of motor severity: ergospirometry showed variance in VO2peak and distance traveled between the light and severe group (p <0.05); others did not show significant differences. No SWTI, VO2Pico presented the difference between the moderate and striking groups (p <0.05) and the distance traveled between the light, striking and severe groups (p <0.05). Conclusion: SWTI is not similar to ergospirometry in the hemiparetic population due to stroke. Severe patients have poorer performance in both tests compared to the mild and moderate group, according to a Fugl-Meyer scale.
Teste ergoespirométrico, avaliação padrão ouro da aptidão cardiorrespiratória, não é um teste economicamente acessível e de fácil aplicabilidade, especialmente para pacientes com sequela de Acidente Vascular Cerebral (AVC). Assim, testes de campo como o Shuttle Walk Test Incremental(SWTI) podem ser outra opção de avaliação da função cardiorrespiratória. Objetivo: Comparar as respostas ventilatórias, metabólicas e cardiovasculares, obtidas pelo SWT e teste ergoespirométrico, em hemiparéticos decorrente de AVC. Objetivo secundário foi comparar os resultados das avaliações ventilatórias com o comprometimento motor leve, moderado, marcante e severo, dos pacientes hemiparéticos. Metodologia: estudo transversal, com 20 indivíduos hemiparéticos, comprometimento motor (05 leves, 04 moderados, 05 marcantes, 06 severos), 58±10 anos, 08 mulheres e 12 homens. Foram avaliados o consumo do VO2máximo(VO2), ventilação(VE), dessaturação, frequência cardíaca(FC) e pressão arterial(PA), durante o SWTI e ergoespirometria, realizados em dois dias, intervalo de 48h. Resultados: SpO2 foi semelhante (97[96-98]; 97[94-97]) respectivamente no SWT e ergoespirometria. Foram diferentes: as variáveis metabólicas VO2Pico (18±4; 24±4), cardíacas FCPico(101±17; 115±15), PA Sistólica(140[140-147]; 160[140-160]) e diastólica(85±6; 90±12), esforço percebido dispnéia (2±1; 3±1), fadiga(2[1-4]; 4[2-6]) e distância percorrida(248±154; 409±216). Comparação entre grupos de gravidade motora: ergoespirometria mostrou variância no VO2pico e distância percorrida entre o grupo leve e severo (p<0,05); demais não mostraram diferenças significativas. No SWTI, o VO2Pico apresentou diferença entre os grupos moderado e marcante(p<0,05) e na distância percorrida entre os grupos leve, marcante e severo(p<0,05). Conclusão: O SWTI não é similar à Ergoespirometria na população hemiparética decorrente de AVC. Os paciente severos tem menor desempenho em ambos os testes em comparação com o grupo leve e moderado, de acordo com a escala de Fugl-Meyer.

Objetivo: Avaliar o fluxo assistencial e a incidência do Teste do Reflexo Vermelho (TRV) alterado em nascidos vivos das DRS II, VI, IX e XI do estado de São Paulo, por meio de informações fornecidas pela Linha de Cuidados do Exame do Olhinho. Métodos: Realizado um estudo observacional, longitudinal e retrospectivo, por meio da análise de dados do sistema de informações da Central de Regulação e Ofertas de Serviços de Saúde (CROSS). Foram analisados dados referentes ao resultado do Teste do Reflexo Vermelho (normal, duvidoso ou alterado) no período de outubro de 2015 a setembro de 2016, das Maternidades, dos Hospitais que realizam parto, dos Centros de Reteste (destino 1) e dos Centros de Referência (destino 2), da região que tem como destino 2 o Hospital das Clínicas da Faculdade de Medicina de Botucatu (HCFMB) – UNESP (DRS II, VI, IX e XI do estado de São Paulo). Resultados: Observou-se que 257 RN tiveram o TRV classificado por médicos não oftalmologistas como alterado/duvidoso nas maternidades e em hospitais que realizam parto, sendo 63 no DRS II, 115 no DRS VI, 33 no DRS IX e 46 no DRS XI. Considerando o número total de 55.291 NV, em média 0,465% dos testes realizados nas maternidades/ hospitais da região foram classificados como alterados ou duvidosos, necessitando de exame com o oftalmologista (aproximadamente 1:200 NV). Dos 236 RN que passaram pelo reteste, sete (2,96%) tiveram o teste confirmadamente alterado. Sendo assim 97,04% dos testes das maternidades/ hospitais foram falso positivos. Dos sete RN com TRV alterado, quatro (57,2%) não chegaram ao destino 2, um faleceu, dois não foram agendados e outro não compareceu. Não consta reconvocação ou busca ativa destas crianças no sistema. Os três RN atendidos pelo HCFMB (destino 2) tiveram os seguintes diagnósticos: catarata polar anterior no olho direito, membrana inflamatória retiniana em olho esquerdo e coriorretinite por toxoplasmose bilateral. Conclusão: A incidência do Teste do Reflexo Vermelho confirmadamente alterado foi de 1,27: 10.000 nascidos vivos e o nosso estudo evidenciou falhas no fluxo assistencial quanto ao agendamento, busca ativa e/ ou registro de pacientes faltosos.
Objective: To review the flow of healthcare assistance and the incidence of abnormal results of Red Reflex Tests (RRT) in live births reported by the Regional Healthcare Departments DRS II, VI, IX and XI in the state of São Paulo, using information provided by the Eye Examination Healthcare Line. Methods: An observational, longitudinal and retrospective study was conducted using data from the Central de Regulação e Ofertas dos Serviços de Saúde -- CROSS [Centre for Control and Provision of Healthcare Services]. The study covered results of Red Reflex Tests (normal, inconclusive, abnormal) throughout the period October 2015 to September 2016 conducted at Maternity Units, Delivery Hospitals, Retest Centres (Destination 1) and Specialized Centres (Destination 2) in the region which had, as Destination 2, the Hospital das Clínicas da Faculdade de Medicina de Botucatu*HCFMB) [Botucatu Medical School General Hospital] UNESP (DRS II, VI, IX and XI of the state of São Paulo). Results: It was observed that the RRT for 257 neonates was classified by nonophthalmologists as altered / inconclusive in Maternity hospitals and Delivery hospitals, 63 in DRS II; 115 in DRS VI; 33 in DRS IX; and 46 in DRS XI. Considering a total of 55,291 neonates, on average 0.465% of tests conducted at Maternity hospitals / hospitals in the general region were classified as abnormal or inconclusive and required examination by an ophthalmologist (approximately 1:200 neonates). Of the 236 neonates who underwent retesting, seven (2.96%) had the abnormal diagnosis reconfirmed. Thus, 97.04% of tests conducted at Maternity / Delivery hospitals were false positive. Of the seven neonates with abnormal RRT, four (57.2%) did not make it to Destination 2; one died; two were not scheduled; and another did not turn up on the scheduled date. No recall or active search for these infants was recorded in the system. The three children treated at the HCFMB (Destination 2) were diagnosed to have: anterior polar cataract in the right eye; retinal inflammatory membrane in the left eye; and bilateral toxoplasmosis chorioretinitis. Conclusion: The incidence of confirmed diagnoses of abnormal Red Reflex Tests was 1.27: 10,000 live births, and our study showed evidence of flaws in the flow of healthcare assistance, mainly in relation to scheduling active search and/or recording patients who failed to attend.

Running automated tests can be a time-consuming task, especially when doing regression testing. If the sequence of the execution of the test cases is arbitrary, there is a good chance that many of the defects are not detected until the end of the test run. If the developer could get the failing tests first, he would almost immediately be able to get back to coding or correcting mistakes. In order to achieve this, we designed and analyzed a set of test case prioritization techniques. The prioritization techniques were compared in an experiment, and evaluated against two existing techniques for prioritizing test cases.Our implementation of the prioritization techniques resulted in a tool called Pritest, built according to good design principles for performance, adaptability and maintainability. This tool was compared to an existing similar tool through a discussion.The problem we address is relevant for the increased popularity of agile software methods, where rapid regression testing is of high importance. The experiment indicates that some prioritization techniques perform better than others, and that techniques based on code analysis is outperformed by techniques analyzing code changes, in the context of our experiment.

Full textAbstract:
Steel media wear has been well studied and quantified; one method of quantification is the Comminution Dynamics Lab's Total Media Wear model. It combines simulations, abrasion and corrosion experimental trials to determine wear for the components of milling and grinding ores and minerals for the mining industry. Breakage is an important measure of process efficiency, the greater the number of breakage events per unit energy consumed, the greater the throughput and production. The classic breakage parameter, the Bond Work Index generates an energy term used by mill operators to determine this performance criterion. It has been suggested that the abrasion test, used in the Total Media Wear Model, would be a suitable alternative to the labour and time-consuming Bond Locked-cycle Test. Extensive tests were performed in order to ascertain the possibility of obtaining these two desired results from a single two-minute test. Different steel media samples were tested at different energy levels, and finally by testing under wet and dry conditions. Dry and wet testing did not generate the same wear results. Wear and breakage rates were higher under wet conditions. In general, the size distribution of the abrasive feed evolved into a product with a finer size distribution. Statistical analysis of the data obtained suggests that there is indeed a linear relationship between the energy input into the system and the resultant Work Index value. These results support the suggestion that this test will be able to recreate the Bond Work Indices for minerals; however, more work is required in order to build a working database and determine appropriate correlation factors.L'usure des composants ferriques dans les procédés minéralurgiques et un sujet bien étudié. Le laboratoire « Comminution Dynamics » a McGill à crée un modèle nommé « Total Media Wear Model » pour prédire le temps de l'avance nécessaire avant lequel il faudra remplacer les blindages et boulettes. Cette modèle comprend des simulations informatiques et des tests de laboratoire. Une autre mesure utilisée par les contremaitres et operateurs c'est le « Bond Work Index ». L'index donne une valeur approximative pour prédire la consommation d'énergie des moulins. Un test du style « Bond » exige beaucoup d'effort, et temps. Récemment, il a été suggérer qu'on pouvait obtenir des valeurs pour le « Bond Work Index » en utilisant un procédé modifié pour un des tests du « Total Media Wear Model ». Différentes nuances d'acier on été testé avec des niveaux d'énergie variées et sous des conditions sec et humide. Les résultats on démontré que les tests sec/humides n'était pas nécessairement équivalent, de plus, un changement dans la distribution granulométrique s'est produit entre la charge et le produit. Et finalement, l'analyse des données suggère qu'il y a une relation entre la valeur calculée de « Work Index » et l'énergie introduit dans la système. Ces résultats confirment les croyances qu'on pourra déterminer la valeur de « Bond Work Index » en même temps que les données du « Total Media Wear Model ». Cependant, il faudra des tests supplémentaires pour plusieurs types de minéraux. Cela pourra crée une base de données avec lequel des facteurs de corrélations pourront être déterminer.

Full textAbstract:
A series of studies were conducted to investigate the validity of a group oral test as administered at a university in Japan. The research investigated the sources of test score variance and asked to what extent candidates' group discussion test scores were reliable measures of their proficiency. The research also investigated to what extent the discourse in the group discussion test task was generalizable to discourse on other kinds of group oral tasks. Three studies were conducted. Study 1 was a repeated measures design in which 113 candidates were tested on the discussion task on two successive occasions, and the consistency of their test scores was analysed. In Study 2,188 candidates were tested on the group discussion task and other estimations of their proficiency were additionally collected. The amount of talk candidates produced in the test was analysed in order to find whether this affected the scores they received. Study 3 was also a repeated measures design in which 64 candidates were tested on three different group oral tasks: - II -discussion,c onsensus-reachinga, nd picture difference. The candidates' test scores and discourse were analysed to find how generalizable their performances were across the task types. Additionally, the candidates' reactions to the tasks were collected through questionnaires and interviews. The findings show that contextual factors such as discussion topic, group interlocutors, and task characteristics led to significant variation in discourse and test scores across test occasions. The findings further show that the group discussion task elicited only a limited range of interactions, and therefore may not be representative of the language use domain. The implications are that test designers can elicit a wider range of interactions from candidates in group tests by introducing task characteristics which increase goal orientation and reactivity. This also lessens the impact of discussion topic and inter-personal group dynamics on candidates' performances

Full textAbstract:
Automated tests have become the most sought after method of testing in today’s market. Automating systems is generally found to be cheaper, faster and more reliable than manually operating them. For this reason many companies decide to make the switch over to this inexpensive yet efficient way of testing, only to realize that their costs have in fact gone up. The reasons for this could be poor planning, automating too much too soon or even automating unnecessary parts of the system. This study takes a closer look at the effects of automating tests used on interlocking systems. A tool has been developed as a part of the automated tests at Bombardier. The main function of the tool is to speed up the testing process by automatically generating test cases rather than having a worker write them down. The aim of this paper is to present this recently developed tool and show how its use significantly reduces testing time, costs and workload compared to the manual tests used today.

Full textAbstract:
The purpose of this dissertation is to examine how the method used to a score situational judgment test (SJT) affects the validity of the SJT both in the presence of other predictors and as a single predictor of task performance. To this end, I compared the summed score approach of scoring SJTs with item response theory and multivariate items response theory. Using two samples and three sets of analyses, I found that the method used to score SJTs influences the validity of the test and that IRT and MIRT show promise for increasing SJT validity. However, no individual scoring method produced the highest amount of validity across all sets of analyses. In line with previous research, SJTs added incremental validity in the presence of GMA and personality and, again, the method used to score the SJT affected the incremental validity. A relative weights analysis was performed for each scoring method across all the sets of analyses showing that, depending on the scoring method, SJT score may account for more criterion variance than either GMA or personality. However, it is likely that the samples were influenced by range restriction present in the incumbent samples.

This study evaluated empirically the Test for Examining Expressive Morphology and the Patterned Elicitation Syntax Test with Morphophonemic Analysis to determine their capacity to aid in answering the following diagnostic questions: (1) "Is there a language impairment" and (2) "What are the specific areas of deficit?" For the first question, a discriminant analysis using 40 preschool children (20 with specific language impairment (SLI), and 20 with normally developing language) revealed 90% sensitivity and 95% specificity for each test. For the second question, an item analysis revealed inconsistent pass/fail rates and low point-to-point agreement for SLI children's performance on items targeting the same morphosyntactic structure across tests. Given their high discriminant capacity, but inconsistent item-level performance, both tests proved appropriate diagnostic tools for question 1 but inappropriate for question 2.

Full textAbstract:
The present study was designed to assess the role of response time on the Category Test of the Halstead-Reitan Neuropsychological Test Battery (HRNB). The intent was to define the underlying constructs of the Category Test more particularly, the speed of performance by examining response time to individual slides of the Category Test.Seventy-two normal adult volunteers were administered the complete HRNB. Average response times were computed for correct (CRT), incorrect (IRT), and total (TRT) scores on the Category Test. The efficacy of using response measures (CRT, IRT, and TRT) to predict Category performance was examined in the context of other HRNB variables that loaded factorially with the Category Test, more specifically: TPT-time, memory, and location, Trails B, WAIS-R Block Design, and WAIS-R Object Assembly.A step-wise multiple regression analysis was computed using the above HRNB and response time measures to predict Category error scores. Results from this analysis indicated that TPT-location, TRT, and IRT contributed significantly (p<.05) in the prediction of Category scores. Approximately 15% of the variability in Category scores was explained by a measure of spatial memory (TPT-location) and an additional 15% was accounted for by psycho-motor speed (TRT and IRT). The significant contribution of response time in defining the underlying construct of the Category Test was discussed in terms of possible implications for enhancing the neuropsychological significance of the Category Test.
