<p>Children with cleft lip and palate (CLP) and children with specific language impairment (SLI) may be affected emotionally and psychosocially by their disorders. Thus, it is important to investigate the psychosocial risk factors that these children are exposed to. The aim of this study was to examine how parents assess the emotional and psychosocial well-being of children with CLP and children with SLI, and if the two parental groups differ in their assessments using the standardized instrument Child Behaviour Checklist (CBCL). Participants in the study were the parents of ten children with unilateral and bilateral CLP between ages 6;7-9;0 (mean age 7;5) and the parents of 13 children between ages 6;4-8;8 (mean age 7;3) who are attending preschools and schools for children with SLI.

The scores in the domains "withdrawn" and "delinquent behaviour" were significantly lower for the group of children with CLP who also had lower total mean scores of CBCL compared to the standardization group. The children with SLI had significantly higher mean scores for all domains compared to this group, indicating that these children with SLI were more emotionally and psychosocially affected than the other groups. Correlations between CBCL and CHQ were found for the children with CLP and the children with SLI.<strong> </strong></p> / <p>Barn med läpp-käk-gomspalt (LKG) och barn med språkstörning kan påverkas emotionellt och psykosocialt på grund av sina avvikelser.

Inflammatory Reactions in Peritonitis and Malignant Obstructive Jaundice : Clinical and Experimental Studies with Special Emphasis on the Cellular Immune Response

Österberg, Johanna January 2005 (has links)
<p>Patients with peritonitis or malignant obstructive jaundice (HPB<sup>+</sup>) have an increased morbidity and mortality due to sepsis. An altered cell-mediated immunity in the intestinal mucosa might promote gut barrier failure, increased endotoxin and cytokine release and bacterial translocation (BT) in these conditions. A clinically relevant rat model of polymicrobial peritonitis induced sepsis by cecal ligation and puncture (CLP) was used. Septic animals demonstrated a superficial injury in the small intestinal mucosa, and a significant reduction in T lymphocytes in the villi, as well as increased number of macrophages in the villi and in the MLNs as compared to sham. CLP caused increased concentration of TNF-α and IL-6 in ascitic fluid. CLP + the immunomodulator Linomide decreased the TNF-α level, reduced mucosal damage and attenuated the changes in T lymphocytes and macrophages observed following CLP. CLP + selective cyclooxygenase (COX)-2 inhibitor (SC-236) or nonselective COX inhibitor (indometacin) decreased the amount of macrophages in the mucosa and the MLNs compared to untreated CLP. CLP + indometacin decreased T lymphocytes in the villi and MLNs. SC-236 + CLP reduced mucosal injury and cytokine release as compared to indometacin. An increased rate of apoptosis in both the mucosa and MLNs was seen following CLP; COX inhibitors enhanced this phenomenon in the MLNs.</p><p>BT occurred infrequently in patients with acute peritonitis and in HPB<sup>+</sup> there was no evidence of BT.

The system data input can be done by not-specialized people using scenarios composed by time lines. These time lines demonstrate graphically the sequencing details of the PLC input and output permitting the programming of systems that uses memory like inter-locking contacts and the use of timers. Since GP is great dependent of its initial simulation parameters, thousand of simulations have been done to determine the better kind of configuration of cross-over and mutation / Essa pesquisa propõe a aplicação da técnica de inteligência artificial programação genética (PG) para facilitar o trabalho de programação de controladores lógico programáveis (CLP) através da geração automática de programas Ladder e Instruction List. A entrada de dados do sistema de automação é feita de forma leiga a partir de cenários compostos por linhas do tempo. Essas linhas do tempo demonstram graficamente os detalhes do seqüenciamento dos acionamentos das entradas e saídas do CLP permitindo a programação de sistemas que utilizam memória como os inter-travamentos e o uso de temporizadores. Como a PG é altamente dependente dos parâmetros iniciais de simulação, foram feitas milhares de simulações para determinação das melhores formas de configuração dos parâmetros de reprodução por cross-over (cruzamento) e mutação

Généralisation des Jeux Combinatoires et Applications aux Langages Logiques

Loddo, Jean-Vincent 16 December 2002 (has links) (PDF)
La théorie des jeux a développé, à ses débuts, une vocation pour les sciences sociales et économiques, avec des applications disparates, comme par exemple le traitement de données médicales. Elle apparaît aujourd'hui comme un paradigme de concepts et de techniques très général, dont le potentiel reste encore à exploiter en informatique. Dans cette thèse nous étudions une branche particulière, la théorie des jeux combinatoires (à deux joueurs), pour en tirer bénéfice dans le domaine, très actif, des sémantiques formelles des langages de programmation. D'un jeu, nous pouvons séparer l'aspect syntaxique, inhérent aux dénouements possibles des matchs, de l'aspect sémantique, inhérent aux prévisions sur le gagnant et la quantification de son gain (en termes d'un enjeu quelconque, tel que l'argent ou le préstige). Pour modeliser la notion de gain, la structure d'évaluation choisie ne doit pas forcément être celle des booléens (gagné ou perdu), ou celle des entiers naturels ou relatifs. Il suffit qu'elle vérifie des propriétés, assez faibles, garantissant l'existence d'une sémantique même lorsque le jeu donne lieu à des matchs infinis, comme dans le cas du jeu de la bisimulation entre processus concurrents, et du jeu de la programmation logique. Dans ce travail, nous étudions la caractérisation sémantique d'un langage logique (avec ou sans contrainte) en termes de jeu à deux joueurs. Au-delà du modèle intuitif des jeux, dont la valeur pédagogique mériterait d'être approfondie, une telle interprétation permet de réutiliser un des algorithmes les plus utilisés dans la théorie des jeux combinatoire, Alpha-Bêta, comme moteur de résolution pour les langages logiques. Les résultats récents et spectaculaires obtenus par les programmes d'échecs (souvenons-nous de la défaite du champion du monde Kasparov contre le programme Deep Blue d'IBM) témoignent d'une forme d'intelligence artificielle développée dans ces programmes qui peut être transposée et exploitée dans la résolution des langages logiques. La résolution d'interrogations existentielles conjonctives dans une théorie de clauses de Horn du premier ordre est en particulier concernée. En effet, la capacité d'Alpha-Bêta à simplifier le calcul ou, en d'autres termes, sa capacité à éliminer les coups inintéressants, n'est pas intimement liée à un type de jeu ou à un type de gain particuliers, mais demande juste des propriétés algébriques qui sont satisfaites dans le jeu de la programmation logique. La correction d'Alpha-Bêta est prouvée de façon formelle pour un éventail de structures très large. Les valeurs calculées pourront être aussi bien des entiers naturels, comme dans le cas du jeu d'échecs, que des substitutions ou des contraintes, comme dans le cas des langages logiques.

Implementação de controle supervisório em CLPs usando linguagem de alto nível / Implementation of supervisory control in PLCs using high-level language

Almeida, Suzana Ribas de 15 February 2012 (has links)
Made available in DSpace on 2016-12-12T17:38:31Z (GMT). No. of bitstreams: 1 SUZANA RIBAS DE ALMEIDA.pdf: 2655112 bytes, checksum: 346dca905796b24136deb70b7263fb5b (MD5) Previous issue date: 2012-02-15 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Nowadays the competition between companies is increasing. In a production system, efficiency, speed and flexibility are important means for cost reductions. The complexity of automation systems has been increasing, which makes necessary the implementation of more efficient control programs, free of errors and easy to maintain. However, in most practical applications the solution of these problems is dependent on designer's experience and doesn t follow a formal methodology, which results in programs with errors and difficulties to understand and maintain, since only the designer understands the adopted solutions. The Supervisory Control Theory (SCT) is a method extensively researched in academic circles for the synthesis of control logic of automated systems. It allows control problems to be solved in a formal way, ensuring a minimally restrictive and no blocking solution that meets the control specifications. However, this theory is not widely used in industrial environments yet, once the methods for implementation of supervisors obtained by TCS are still deficient. Thus, the intention of this Dissertation consists of showing a methodology for implementation of supervisory control in Programmable Logic Controllers (PLCs). In this work, the synthesis of supervisors is made in accordance to local modular approach, which brings the benefits of a formal methodology and allows exploring the modularity of the plant and the control specifications. The implementation is based on an architecture structured in three levels: supervisor, interface and system to be controlled. For the implementation in CLP three different programming languages are applied: the high-level languages Sequential Function Charts (SFC) and Structured Text and the low-level Ladder Diagram language in some parts. The development of the methodology was based on two works: a doctoral thesis by Vieira (2007) and master thesis by Cruz (2011) and brought together the advantages presented in each one of these. To compare the proposed methodology and the two mentioned methods, several tests were made on a manufacturing cell available at PUCPR and simulations on a PLC and computer as well. The results show that the use of the methodology proposed in this work makes possible to implement PLC programs that are able to treat all non-controllable events occurred in the system to be controlled and treat one controllable event by each control cell in the same scan cycle. Furthermore, the use of high-level languages results in a program of easier interpretation and maintenance, also enabling reutilization of codes. In this work some problems related to CLPs implementations are also showed and proposals for solving them are presented, as properties as well that, if accepted, ensure that the problem does not occur. / Hoje em dia a competitividade entre as empresas está cada vez maior. Em um sistema de produção, a eficácia, a velocidade e a flexibilidade são importantes, pois significam redução de custos. Os sistemas de automação atuais estão cada vez mais complexos, justificando a necessidade de programas de controle mais eficientes, sem erros e de fácil manutenção. Entretanto, na maioria das aplicações práticas a solução destes problemas é feita com base na experiência do projetista, não seguindo uma metodologia formal, o que resulta em programas com erros e de difícil entendimento e manutenção, uma vez que só o projetista entende perfeitamente as soluções adotadas. A Teoria de Controle Supervisório (TCS) é um método para a síntese da lógica de controle de sistemas automatizados. Ela permite que problemas de controle sejam solucionados de modo formal, garantindo uma solução minimamente restritiva e não bloqueante e que atenda às especificações de controle. Entretanto, esta teoria ainda não é amplamente adotada em ambientes industriais, sendo a carência de métodos de implementação dos supervisores obtidos via TCS um elemento que contribui para que isso aconteça. Assim, esta dissertação se propõe a apresentar uma metodologia de implementação de controle supervisório em Controladores Lógicos Programáveis (CLPs). Neste trabalho, a síntese de supervisores é feita de acordo com a abordagem modular local, que traz os benefícios de uma metodologia formal e ainda permite explorar a modularidade da planta e das especificações de controle. A implementação é baseada numa arquitetura estruturada em três níveis: supervisor, interface e sistema a ser controlado. Para a implementação em CLP são empregadas três linguagens distintas de programação, as linguagens de alto nível Sequential Function Charts (SFC) e Structured Text, bem como a linguagem Ladder Diagram em algumas partes. O desenvolvimento da metodologia foi baseado em dois trabalhos: a tese de doutorado de Vieira (2007) e a dissertação de mestrado de Cruz (2011) e permitiu reunir as vantagens apresentadas em cada um destes. Para comparação entre a metodologia proposta e as duas metodologias citadas, foram feitos diversos testes em uma célula de manufatura existente na PUCPR, bem como simulações em CLP e em computador. Os resultados mostram que a metodologia proposta neste trabalho permite a implementação de programas em CLP que, num mesmo ciclo de varredura, são capazes de tratar todos os eventos não controláveis ocorridos na planta e ainda um evento controlável por célula de controle. Além disso, o uso de linguagens de alto nível resulta em um programa de mais fácil interpretação e manutenção, possibilitando ainda o reaproveitamento de códigos. Nesta dissertação também são abordados alguns problemas de implementação da estrutura de controle supervisório em CLPs, apresentando-se propostas para solucioná-los, bem como propriedades que, se atendidas, garantem que o problema não ocorra.

Det är inte bara en PFAS : Om begränsningen av evighetskemikalier i EU / It is not just a PFAS : On the restriction of forever chemicals in the EU

Fredman Smith, Andrea January 2024 (has links)
I Europa kan omkring 20 miljoner människor vara exponerade för dricksvatten som innehåller evighetskemikalien PFAS. Tidigare har försök att begränsa enskilda PFAS-ämnen endast resulterat i att det förbjudna ämnet i fråga har bytts ut till ett annat PFAS-ämne. Den europeiska kemikaliemyndigheten (ECHA) har utfärdat rapporten Annex XV Restriction Report, Per- and polyfluoroalkyl substances (PFASs) där två förslag om hur begränsningen av PFAS-ämnena kan utformas har introducerats. Rapporten presenterar möjligheten att utfärda ett generellt förbud av alla PFAS-ämnen. Om beslutet om en generell begränsning fattas i den Europeiska unionen (EU) kan det bli ett av de största förbuden någonsin mot kemiska ämnen i Europa. Arbetets syfte är att utreda huruvida de presenterade förslagen för hur PFAS ska begränsas i begränsningsrapporten är ändamålsenligt utformade utifrån konceptet av effektorienterad lagstiftning. Begränsningsförslagen analyseras med hjälp av miljörättsvetenskaplig metod och ställs i relation till begreppet hållbar utveckling. Att undersöka om begränsningsförslagen är ändamålsenligt utformade är särskilt intressant, eftersom ett beslut som begränsar PFAS-användningen enligt de presenterade förslagen skulle påverka såväl EU:s ekonomi som ekologi. Om ett juridiskt beslut fattas, måste det vara väl avvägt och nå önskad effekt, särskilt när det påverkar hela EU. I uppsatsen utreds vidare vilket begränsningsförslag som bäst tillgodoser behovet av god dricksvattenkvalitet och människors hälsa, samt hurbegränsningsförslagen förhåller sig till en hållbar utveckling. Efter en analys av begränsningsrapporten dras slutsatsen att båda begränsningsförslagen är ändamålsenligt utformade utifrån effektorienterad lagstiftning. Begränsningsförslagen är utformade så att de riktar begränsningar mot aktörer (människor) för att motverka att deras agerande har negativ inverkan på reaktörer (naturen och miljön). Begränsningsförslagen är dock olika orienterade. Begränsningsförslag två är mer aktörsorienterat än begränsningsförslag ett, eftersom begränsningsförslag två tar en större hänsyn till industrisektorns intressen. Båda begränsningsförslagen har ändå en starkt reaktörsfokuserad karaktär, eftersom de hindrar PFAS-användning från att förorena miljön. Ohållbar miljöpåverkan till följd av användning av PFAS kan motiveras i vissa fall, om det tillgodoser allmänna intressen eller är nödvändigt av lagtekniska skäl. Vidare dras slutsatsen att det begränsningsförslag som bäst tillgodoser behovet av goddricksvattenkvalitet är begränsningsförslag ett. Behovet av god hälsa bör kunna tillgodoses bäst genom begränsningsförslag ett för den största gruppen människor, eftersom detbegränsningsförslaget inte tillåter några undantag från PFAS-förbudet. Ett begränsningsförslagsom inte tillåter undantag möjliggör för en mindre mängd PFAS-exponering. Den gruppmänniskor i EU som är i behov av PFAS i medicinskt syfte kan dock dra nytta av att begränsningsförslag två tillåter användningsspecifika undantag. Avslutningsvis dras slutsatsen att båda begränsnignsförslagen leder till en reduktion av PFAS-utsläpp samt PFAS-exponering och är således hållbara utifrån ekologisk hållbarhet. Utifrån ekonomisk hållbarhet bör begränsningsförslag två vara mest gynnsamt, eftersom det är mest troligt att tillåta en hanterbar omställning för de olika industrisektorerna. Utifrån sociala aspekter av hållbarhet såsom hälsa, välbefinnande och privatekonomi, bör begränsningsförslagett vara det mest gynnsamma begränsningsalternativet. Detta trots att begränsningsförslag två tillåter medicinsk användning av PFAS samt tar en större hänsyn till industrisektorns ekonomi,vilket påverkar enskildas privatekonomi.

Osoby způsobilé v oblasti rizik / Qualified persons in the field of occupational risks

Fichtner, Jan January 2022 (has links)
Qualified persons in the field of occupational risks Abstract Qualified persons in the field of occupational risks are persons dealing with different levels of risk, different extent and type of risks. In this set is not only the person for health and safety, but there are other qualified persons as well. For example, a qualified person who provides and performs the ccupational health services, a qualified person for fire protection, a construction safety coordinator, as well as an inspection technician of dedicated technical equipment, etc. A key qualified person in occupational risk and health and safety prevention is a person who assist employers in occupational risk prevention by managing risk identification, providing risk assesments, identification of source and risks causes and incidents. This person takes care about risk factors on worplaces such as microclima, chemical and biological hazards, noise, ergonomy and many others risks and continuosly advises employers of identificated risk on workplaces. He leads as a expert in health and safety, but not responsible, for applying right and effective principles of work safety and accident prevention and provide high qualified consultating job for employers. As well as is need to be noticed that employers has a legal obligation to have minimum one these...
