Thesis deals with the problem of the older school age boys dental injuries in České Budějovice region. The injury means: ?sudden damage of the health by effect of external factors which exceed adaptation options of the human body?. In the sphere of dental injuries the children is the most jeopardized group of population. The most often reason for the children injuries is their imperfect stability. In case of older children and young people there are injuries mostly caused by sport. Teoretical part of my thesis is focused on definition of older school age as well as on anatomy and teeth physiology. The part of thesis also is the enumeration of dental injuries and its treatment. I also mention prosthetic dentistry and the influence of accidents on individual physical and mental health. At the end of teoretical part there is mentioned process of the injured examination, posttraumatic dental hygiene and patient nutrition after teeth accident. Research part finds with the help of questionnaire survey the kinds of dental accidents, circumstances of injuries formation and the influence of accidents on individual physical and mental health in specific age category. The questionnaire survey was evaluated and processed in grafical part of thesis. The part of thesis also is health and educational material which helps to rise the quality of dental hygiene and also contributes to the prevention of dental accidents formation of second degree students at primary schools.

O diagnóstico precoce e o tratamento são imprescindíveis para o controle da hanseníase, pois visam eliminar o mais precocemente possível as fontes de transmissão. O principal critério de cura da doença é o tempo de tratamento, relacionado às doses fixas da poliquimioterapia. O tempo de tratamento dos pacientes multibacilares foi reduzido de 24 para 12 doses em até 18 meses em 1998. Os objetivos desta tese foram: avaliar a detecção de casos de hanseníase entre os contatos dos pacientes e avaliar fatores de risco associados à piora das incapacidades físicas nos pacientes após a alta do tratamento poliquimioterápico com as 12 doses mensais. Dois artigos foram elaborados. O primeiro artigo avaliou características dos pacientes com hanseníase e de seus contatos associadas ao risco de adoecimento entre os contatos. O segundo artigo avaliou fatores de risco relacionados à piora das incapacidades físicas dos pacientes com hanseníase multibacilar, submetidos ao tratamento com 12 doses fixas da poliquimioterapia. Os resultados mostraram que o risco para hanseníase, relacionado aos contatos foi o tipo de convivência com o caso índice. Entre os fatores dos casos índices, a carga bacilar foi o único associado ao adoecimento dos contatos. Além desses fatores, os contatos que apresentam relação de consangüinidade com o caso índice e os contatos dos pacientes com menor nível de escolaridade mostraram maior chance de se apresentarem doentes no momento do diagnóstico do caso índice. A cicatriz BGC e a vacina recebida após o diagnóstico do caso índice contribuíram independentemente como fatores de proteção. A neuropatia piorou em 40% dos pacientes durante o período de 10 anos após a alta do tratamento. Esta piora foi associada à presença de incapacidades físicas e ao número de lesões cutâneas no momento do diagnóstico assim como à presença de neurite durante o acompanhamento. / Early diagnosis and treatment are essential for the control of leprosy disease, since they aim to eliminate as soon as possible sources of transmission. The main criterion for cure of the disease is the treatment time, related to fixed doses of multidrug therapy. The duration of treatment of multibacillary patients was reduced from 24 to 12 doses up to 18 months in 1998. The aim of this thesis is to evaluate the detection of leprosy among contacts of patients and to evaluate risk factors associated with worsening of physical disability in patients after discharge from the treatment with 12 monthly doses. Two articles have been prepared. The first article evaluated characteristics of leprosy patients and their contacts related to risk of disease among the contacts. The second article evaluated risk factors related to the worsening of the physical disabilities of patients with multibacillary leprosy, undergoing treatment with fixed doses of 12 multidrug therapy. The results showed that the risk for leprosy among contacts was related to the type of relationship with the index case. Among the factors of the index cases, the bacterial load was the only factor associated with the disease among contacts. Besides these factors, the contacts that are related to consanguinity with the index case and contacts of patients with lower education level showed a greater chance of presenting patients at diagnosis of the index case. The scar and the BGC vaccine received after the diagnosis of the index case contributed independently as protective factors. Neuropathy worsened in 40% of patients during the 10 years after the discharge of treatment. This worsening was associated with the presence of physical disabilities and number of lesions at time of diagnosis as well as the presence of neuritis during monitoring.

O intérprete da norma jurídica não se deve ater apenas à interpretação gramatical, sobretudo no que diz respeito à responsabilização dispensada à Administração Pública na Lei de Licitação, devendo o intérprete utilizar-se da interpretação lógico-sistemática e teleológica da Lei de Licitação em confronto com o disposto constitucionalmente, permitindo a responsabilização do ente público, nos casos de terceirização. Esta no setor público sofre limitações, diante do comando legal insculpido no inciso II do art. 37 da Carta magna, que exige a prévia aprovação, em concurso público, para a investidura em cargo ou emprego público, à exceção dos cargos de livre provimento. A terceirização no setor público tem como traço diferencial, com o setor privado, a não formação de emprego com a Administração direta, indireta ou fundacional. A terceirização é uma tendência mundial irreversível, mas não podemos deixar que ela seja utilizada para fraudar os direitos dos trabalhadores, contribuindo, deste modo, para a perpetuação das injustiças, tornando-se cada vez mais perversa, o que, em última análise, acaba gerando o fim da própria terceirização. / This study aims to investigate the admissibility of the third party in the public sector, its peculiarities and the liability of the public entity, as there is an absence of a specific procedure in relation to the responsibility in the case of the third party, composed through jurisprudence agreements, finding questionings regarding the liability before what is determined to the Licitation Law in its article 71 in confrontation to the dispositions included in the articles 1st, 37, paragraph, 6th, 170, 173 and 193 of the Federal Constitution. The interpreter of the juridical procedure should not detain themselves only to the grammatical interpretation, above all in regards to the liability bestowed to the Public Administration in the Licitation Law, where the interpreter should use the logic-systematic and teleological interpretation of the Licitation Law in confront to the constitutional determination, allowing the liability of the public entity in the third party cases. The third party in the public sector suffers limitations, before the legal command inscribed in the proposition II of article 37 of the magna letter, which demands the previous approval in a public examination for the investiture in an office or public employment, in exception to the offices of the free administrative acts. The third party in the public sector has as a differential aspect with the private sector, the non-formation of employment with the direct, indirect or foundational Administration. The third party is a worldly and irreversible tendency, but we cannot allow that it is used to fraud the laborers’ rights, contributing to the perpetuation of the injustices, becoming more and more perverse, and that as a last analysis, this ends up by generating the termination of the third party itself.

From that point of view, the main goal of this research is to analyze the influence of the family background as a determiner of the pupil?s performance in the access to Technical and Professional education at IFRN. Secondary data were used from two databases (entrance test and PROITEC) adding up to 19.226 observations to the vacancies offered in the year of 2013. Aiming at achieving the proposed goal, a conceptual model composed of three hypothesis was developed. The results were presented in four stages: stage I presentation of the descriptive statistical results of the two databases; stage II separation of the campi in clusters; stage III analysis of multiple regressions; stage IV analysis of the logistics regressions. Two statistical tests were used to validate the hypothesis: T-test and Wald test. Hypothesis 1 and 2 were confirmed and H3 was refused. The results presented favorable causal connections to the family income and the father school level variables (with bigger effect for fathers with a higher education degree). The mother school level variable did not provide statistical significance for this research. Based on this result, after this work, this institution is to develop a strategic plan to assist in the success rate of students preparing diagnoses in order to diminish the effects of the variables that impacted negatively / Este trabalho compreende uma investiga??o acerca da influ?ncia que as vari?veis de background familiar (escolaridade do pai, escolaridade da m?e e renda familiar) exercem sobre o desempenho de um estudante, candidato ?s vagas dos processos de sele??o (Exame de sele??o e PROITEC) do Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Rio Grande do Norte (IFRN). Nessa perspectiva, o objetivo geral da pesquisa consiste em analisar a influ?ncia do background familiar, como determinante de desempenho do aluno, no acesso ao Ensino T?cnico Profissional do IFRN. Utilizaram-se dados secund?rios correspondentes a dois bancos de dados (Exame de sele??o e PROITEC) perfazendo um total de 19.226 observa??es referente ?s vagas ofertadas no ano de 2013. Buscando alcan?ar o objetivo proposto, formulou-se um modelo conceitual composto por tr?s hip?teses. Os resultados foram apresentados em quatro etapas: etapa I apresenta??o dos resultados das estat?sticas descritivas referentes aos dois bancos de dados; etapa II separa??o dos campi em clusters; etapa III an?lise das regress?es m?ltiplas; e, etapa IV an?lise das regress?es log?sticas. Utilizaram-se dois testes estat?sticos para valida??o das hip?teses: teste T e teste de Wald. As hip?teses 1 e 2 foram confirmadas e, a H3, refutada. Os resultados apresentaram uma causalidade positiva das vari?veis renda familiar e escolaridade do pai (com maior efeito para os pais com ensino superior completo). J? a vari?vel escolaridade m?e n?o obteve signific?ncia estat?stica para este estudo. Com base nesse resultado, ap?s esse trabalho, essa institui??o tem como elaborar um planejamento estrat?gico para auxiliar na taxa de sucesso dos alunos elaborando diagn?sticos a fim de diminuir os efeitos das vari?veis que impactaram de maneira negativa

Despite major advances in laboratory diagnosis techniques, primarily the character of asymptomatic chlamydial infection in both men and in women constitutes the basis for the formation of reservoirs that perpetuate transmission and acquisition of this and other STDs. The asymptomatic in women favors the rise of infection to the upper genital tract, causing injuries that can result in infertility. An examination of population screening for early detection and treatment of asymptomatic infections is the key step in combating this major public health problem. The present study aimed to evaluate the prevalence of infection by C. trachomatis in sexually active women attended the screening program for cervical cancer of the uterus in health facilities in municipalities in different regions of the State of Rio Grande do Norte, and identify factors that may contribute to the spread of this pathogen and its relationship with the lesions of the uterine cervix. It is a cross-sectional study aimed at detecting the presence of genital tract infection by C. trachomatis either in isolated form or in association with human papilloma virus (HPV) infection in asymptomatic women. Were included in this study, a total sample of 1,134 women aged 13-76, mean 34.4 years, from March 2008 to September 2012. Specimens containing exfoliated cells of the epithelium of the uterine cervix were analyzed by examining Pap cytology for the detection of possible injuries, and the polymerase chain reaction (PCR) for detection of plasmid DNA from C. trachomatis and HPV. Infection with C. trachomatis was detected with overall prevalence rate of 8.1% in the isolated form and 2.8% in co-infection with HPV. The infection was detected in 7.4% of women with normal cytology 11.5% of those with atypical cells of undetermined significance (ASC-US) and 16.7% of those with low-grade squamous intraepithelial lesion (LSIL). We observed an association between C. trachomatis and incidence of low-grade squamous intraepithelial lesion (LSIL). The genital tract infection by C. trachomatis alone was associated with education level, ethnicity and parity, revealing that women with higher education, those of non-white ethnicity and those who had three or more pregnancies were more likely to acquire infection. Levels very close to statistical significance were observed for chronological age, age at first sexual intercourse and first pregnancy. There was no association with marital status, number of sexual partners. Co-infection with C. trachomatis and HPV was detected in 2.3% of women with normal cytology, who had 5.1% in ASC-US and 10.4% in those with LSIL. No association was found between infection C. trachomatis and increased risk of HPV infection, but women with simultaneous infection by both pathogens showed greater risk for LSIL. Co-infection was more prevalent among single women, who had in the first sexual intercourse under 18 years and those who had two or more sexual partners over a lifetime / A infec??o genital por Chlamydia trachomatis ? reconhecida atualmente como uma das mais prevalentes infec??es sexualmente transmiss?veis (IST). Apesar dos grandes avan?os das t?cnicas de diagn?stico laboratorial, o car?ter primariamente assintom?tico da infec??o clamidial tanto em homens, quanto em mulheres constitui-se na base para forma??o de reservat?rios que perpetuam a transmiss?o e a aquisi??o desta e de outras IST. A forma assintom?tica em mulheres favorece a ascens?o da infec??o para o trato genital superior, ocasionando agravos que podem resultar em infertilidade. O exame de triagem populacional para a detec??o precoce e o tratamento das infec??es assintom?ticas ? o procedimento chave no combate a este importante problema de sa?de p?blica. O presente estudo teve como objetivo avaliar a preval?ncia da infec??o por C. trachomatis em mulheres sexualmente ativas atendidas pelo programa de rastreamento do c?ncer de colo do ?tero em unidades de sa?de de munic?pios das diferentes regi?es do Estado do Rio Grande do Norte, bem como identificar fatores que podem contribuir para a dissemina??o desse pat?geno e sua rela??o com as les?es da c?rvice uterina. Trata-se de um estudo transversal que visa detectar a presen?a de infec??o do trato genital por C. trachomatis seja na forma isolada, ou em associa??o com o v?rus do papiloma humano (HPV) em mulheres assintom?ticas. Foram estudadas 1.134 mulheres com idade variando de 13 a 76, m?dia de 34,4 anos, no per?odo de mar?o de 2008 a setembro de 2012. Esp?cimes contendo c?lulas descamadas do epit?lio da c?rvice uterina foram analisados por meio do exame citol?gico de Papanicolau para a detec??o de poss?veis les?es, e pela rea??o em cadeia da polimerase (PCR) para detec??o do DNA plasmidial da C. trachomatis e do HPV. A infec??o por C. trachomatis foi detectada com taxa de preval?ncia global de 8,1%, na forma isolada e de 2,8% em co-infec??o com HPV. A infec??o foi detectada em 7,4% das mulheres com citologia normal, 11,3% daquelas com c?lulas at?picas de significado indeterminado (ASC-US) e 16,7% das que tinham les?o intraepitelial de baixo grau (LSIL). Observou-se associa??o entre C. trachomatis e ocorr?ncia de les?o intraepitelial de baixo grau (LSIL). A infec??o do trato genital por C. trachomatis sozinha mostrou-se associada com escolaridade, etnia e n?mero de gesta??es, revelando que as mulheres com maior escolaridade, as de etnia n?o branca e aquelas que tiveram tr?s ou mais gesta??es apresentaram maiores chances de adquirir infec??o. N?veis muito pr?ximos da signific?ncia estat?stica foram observados, para idade cronol?gica, idade do primeiro intercurso sexual e da primeira gesta??o. N?o se observou associa??o com situa??o conjugal e n?mero de parceiros sexuais. A co-infec??o por C. trachomatis e HPV foi detectada em 2,3% das mulheres com citologia normal, 5,1% nas que tinham ASC-US e 10,4% naquelas com LSIL. N?o se observou associa??o entre a infec??o C. trachomatis e aumento de risco de infec??o pelo HPV, mas as mulheres com infec??o simult?nea pelos dois pat?genos apresentaram maior risco de ter LSIL. A co-infec??o foi mais prevalente nas mulheres solteiras, nas que tiveram o primeiro intercurso sexual com menos de 18 anos e nas que tiveram dois ou mais parceiros sexuais ao longo da vida

However, changes in operational processes and parameters, the action of external agents, the kind of maintenance conducted, the means of monitoring, and natural and accidental occurrences completely modify the desired performance of the equipment. The discontinuities that occur in anisotropic materials often and due to different factors evolve from being subcritical to critical acquiring the status of defect and compromising the physical integrity of the equipment. Increasingly sophisticated technological means of detection, monitoring and assessment of these discontinuities are required to respond ever more rapidly to the requirements of industry. This paper therefore presents a VPS (Virtual Pipe System) computational tool which uses the results of ultrasonic tests on equipment, plotting the discontinuities found in models created in the CAD and CAE systems, and then simulates the behavior of these defects in the structure to give an instantaneous view of the final behavior. This paper also presents an alternative method of conventional ultrasonic testing which correlates the integrity of an overlay (carbon steel and stainless steel attached by welding) and the reflection of ultrasonic waves coming from the interface between the two metals, thus making it possible to identify cracks in the casing and a shift of the overlay / Os projetos de equipamentos em geral j? contemplam os esfor?os e os mecanismos de de processo e de par?metros operacionais, a??o de agentes externos, esp?cie de manuten??o aplicada, forma de acompanhamento, ocorr?ncias naturais e acidentes modificam completamente deteriora??o a que estes est?o submetidos, prevendo aproximadamente sua vida ?til, por?m, mudan?as o comportamento esperado dos equipamentos.

The Public Attitude towards Preventive Oncology Examinations The object of this paper is to find out how laic and health professional public uses the potential of preventive oncology examinations and to uncover the barriers in use of these programs from the point of view of the laic and professional public. The public attitude towards preventive oncology examinations is more important these days as the incidence of oncology diseases is growing. Prevention is considered the principal in modern medicine, also from an economic point of view. The attitude of society towards its health is one of problematic public health areas, the attitude of self-responsibility and the underestimated meaning of primary prevention. Moreover, there is a psychological problem related to oncological diseases: the fear of positive findings and the fear of the disease itself which is traditionally connected with incurability, cruel pain and inevitable death. This notion is no longer true. A dictatorial doctor{\crq}s approach to patients in the past has been replaced with cooperative and more equal relation, where the patient takes part in decision making. However, doctors are too busy to find the proper way and proper extent of informing the patient or these doctors often underestimate the importance of a good way of giving this kind of information. This thesis presents current preventive care offered in the Czech Republic and it shows the negative bias towards cancer which is a stumbling block to a more successful fight against oncology diseases. This research was undertaken amongst laic and health public. Quantitative data collection was used in the form of questionnaires. The research file is made up of men and women over 18 years, with or without health occupation. The hypothesis was not proven that laic public use preventive oncology examinations more than health public. The laics use these programs less mostly due to lack of awareness about them. One of the most common obstacles in using preventive programs is the misunderstanding of prevention itself, when people contact a doctor only when they have problems. The results have also shown that laics are not satisfied with the activity of doctors in informing them and that laic public search for information is done less actively. This thesis can be used as a foundation for further discussion about problems of informing the public about preventive programs and for future education of health personnel within oncology matters.
