Με τη ραγδαία ανάπτυξη των ασύρματων επικοινωνιών και την μαζική χρήση τους, εμφανίστηκε το πρόβλημα της διάθεσης των ραδιοσυχνοτήτων του φάσματος, του κύριου αλλά πεπερασμένου πόρου για τις ασύρματες επικοινωνίες. Η κύρια πολιτική πρόσβασης στο φάσμα ραδιοσυχνοτήτων, είναι η εξουσιοδότηση επιλεγμένων χρηστών να μεταδίδουν σε συγκεκριμένο εύρος συχνοτήτων. Παρά την κάλυψη όλων των ραδιοσυχνοτήτων από εξουσιοδοτημένους χρήστες, την αυξημένη ζήτηση και το υψηλό κόστος πρόσβασης, μετά από έρευνες αποδεδείχθηκε ότι μόνο το 70% του φάσματος χρησιμοποιείται αποδοτικά μέχρι σήμερα. Η τεχνολογία του Cognitive Radio αναπτύχθηκε με την προοπτική να επιτύχει αποτελεσματικότερη χρήση του φάσματος, δίνοντας τη δυνατότητα σε μη εξουσιοδοτημένους χρήστες να έχουν πρόσβαση σε συχνότητες που είναι καθόλου ή μερικώς κατειλημμένες από τους εξουσιοδοτημένους χρήστες, στο χώρο και στο χρόνο. Η τεχνολογία του Cognitive Radio εφαρμόζει δυο βήματα. Πρώτα αντιλαμβάνεται την κατάσταση του φάσματος στο χώρο σε συγκεκριμένες χρονικές στιγμές και έπειτα διαθέτει δυναμικά τις ελεύθερες συχνότητες που εντόπισε στους μη εξουσιοδοτημένους χρήστες, η διαδικασίες ονομάζονται ανίχνευση και κατανομή φάσματος αντίστοιχα. Ο μόνος περιορισμός είναι, το εκπεμπόμενο σήμα των μη εξουσιοδοτημένων χρηστών να μην παρεμβαίνει (με τη μορφή θορύβου) στο σήμα των εξουσιοδοτημένων χρηστών. Σε αυτήν την εργασία θα υλοποιηθεί μια μέθοδος της διαδικασίας ανίχνευσης φάσματος και οι τεχνικές που την εφαρμόζουν. Ο κύριος στόχος της ανίχνευσης φάσματος είναι ο εντοπισμός των εξουσιοδοτημένων χρηστών όταν αυτοί εκπέμπουν στις καθορισμένες για τον καθένα συχνότητες. Αυτό επιτυγχάνεται όταν φτάνει το σήμα των εξουσιοδοτημένων χρηστών στην κεραία του μη εξουσιοδοτημένου χρήστη. To βασικό εμπόδιο που παρουσιάζεται για τον εντοπισμό αυτών είναι η εξασθένηση του σήματος του εξουσιοδοτημένου χρήστη εξαιτίας των κακών συνθηκών καναλιού που προκύπτουν από τα φαινόμενα multipath, distance dependent path loss και shadowing. Μελέτες έδειξαν ότι η συνεργασία των μη εξουσιοδοτημένων χρηστών σε ένα δίκτυο μπορεί να ακυρώσει την επίδραση τέτοιων φαινόμενων στη διαδικασία εντοπισμού. Έτσι έχουν αναπτυχθεί ποικίλες τεχνικές ανίχνευσης φάσματος βασισμένες στη συνεργασία των μη εξουσιοδοτημένων χρηστών. Η παρούσα εργασία υλοποιεί μια μέθοδο συνεργαζόμενης ανίχνευσης φάσματος που βασίζεται στην ενέργεια του σήματος. Λόγω του κινδύνου αλλοίωσης αποτελεσμάτων από την παρουσία κακόβουλων χρηστών σε συστήματα συνεργασίας, η τεχνική συνεργασίας που επιλέχθηκε εστιάζει στην προστασία του δικτύου από κακόβουλους χρήστες. Μια τέτοια τεχνική θα συγκέντρωνε όλη την απαιτούμενη επεξεργαστική ισχύ σε έναν μη εξουσιοδοτημένο χρήστη που θα αποτελούσε το κέντρο παραγωγής των αποφάσεων-το fusion center. Στην εργασία αυτή η απαιτούμενη επεξεργαστική ισχύς κατανέμεται σε όλους τους μη εξουσιοδοτημένους χρήστες. Αυτό επιτυγχάνεται εισάγοντας ένα επιπλέον βήμα στη διαδικασία. Οι μη εξουσιοδοτημένοι χρήστες εκτελούν αρχικά μια νέα τεχνική ανίχνευσης φάσματος μεμονωμένα, ώστε η τελική απόφαση του fusion center να αφορά αυτές τις συχνότητες για τις οποίες δεν υπήρξε ταύτιση από την πλειοψηφία τους. Η νέα τεχνική που θα εκτελείται μεμονωμένα από τους μη εξουσιοδοτημένους χρήστες είναι μια τεχνική ανίχνευσης φάσματος που δεν διακρίνεται για τα καλά της αποτελέσματα και η μόνη εγγύηση που μπορεί να προσφέρει είναι ο ακριβής εντοπισμός των συχνοτήτων στις οποίες οι εξουσιοδοτημένοι χρήστες δεν μεταδίδουν, θυσιάζοντας πιθανώς κατειλημμένες συχνότητες. Η στοιχειώδης λειτουργία αυτής της τεχνικής σε συνδυασμό με τις ανύπαρκτες απαιτήσεις σε δεδομένα εκ των προτέρων γνωστά, την χαρακτηρίζει πλήρως κατάλληλη για πρώτο βήμα στη μέθοδο που αναπτύχθηκε. / Due to rapid growth of wireless communications and the massive use of them, the problem of sharing the radio spectrum, the main though finite source of wireless communication, made its appearance. The main radio spectrum access policy is to predefine users -named primary- for transmitting to particular radio frequencies. Nevertheless the authorization of the whole the radio spectrum, given the strong competition and the high financial cost for access, doesn’t exploit completely the source. On the contrary, researches have shown that only the 70 % of the radio spectrum is effectively used. The Cognitive Radio technology was developed with the prospect to achieve a more effective use of spectrum, by giving the chance of transmission to non authorization users -secondary- in frequencies which are partially or completely unoccupied with primary users’ signals, from the perspectives of time and space. Cognitive Radio technology applies two processes. At first it senses the spectrum current flow in particular space and time periods, then it dynamically sharing those available frequencies which it sensed, to secondary users. These processes named as Spectrum Sensing and Spectrum Access respectively. The only restriction define to that, transmitted signal of secondary users is forbidden from interfering with primary user signal. In this study, a method of Spectrum Sensing process and individual techniques will be developed. The main objective of Spectrum Sensing process is to determine primary users when they transmit to predefined frequencies. This can be accomplished provided that the signal of primary user can be received from secondary user. Signal deterioration due to channel conditions could be a reason for secondary users in order to not receive primary user signal. Some of these conditions are multipath, distance dependent path loss και shadowing phenomenon. Researches have shown that the secondary users’ cooperation can avoid the effect of those conditions in spectrum sensing process. Thus a variety of spectrum sensing techniques have been developed, which are based on secondary users’ cooperation. In the present study is performed an energy based cooperative spectrum sensing method. Due to the possibility of cooperating with malicious users in the process, the performed cooperation technique focuses on protection from malicious users. Note that such a technique will concentrate the whole computing power on a single secondary user, which one make the final decision and named fusion center. The method of this study distributes the computing power among all the secondary users. That happens by adding one more step in the process. Secondary users firstly execute a spectrum sensing technique individually, in order the process of fusion center to affect only those frequencies, which secondary individual decisions achieved a degree of unanimity for. The individual technique executed by secondary users is not typical of good results in sensing the primary users who transmit, however it gives a guarantee of small values in false alarm possibility. The fundamental operation of this technique in coexistence with very few a-priory requirements made it the appropriate technique for the first step of our method.

Orientador: Carlos Magno Castelo Branco Fortaleza / Resumo: Illicit drug users (IDUs) are recognized as a group at particular risk for staphylococci. In this population the first outbreak of community-associated Staphylococcus aureus (CAMRSA) was described. However, most studies relating S. aureus and MRSA to drug abuse address users of intravenous substances. In Brazil, most dependents are users of inhaled drugs, especially crack. A proportion of these IDUs have multiple passages through recovery clinics. Another institutionalized group still relevant in Brazil are patients with long-term hospitalizations in psychiatric hospitals. In spite of the psychiatric reform and its emphasis on deinstitutionalization, aspects of social vulnerability and abandonment by relatives also determine the residence of patients in psychiatric hospitals. The two groups described above are exposed to different epidemiological pressures and are both at higher risk of invasive staphylococcal disease and in a strategic position for maintenance and dissemination of isolates. The objective of this study was to identify the prevalence and predictors of the carrying of S. aureus and MRSA in IDUs admitted to the Hospital of Reference for Alcohol and Drugs (SARAD) and patients residing in the Psychiatric Hospital Cantídio de Moura Campos, both located in Botucatu , São Paulo State, Brazil. Molecular characterization of MRSA isolates was performed. A total of 220 subjects were enrolled, 138 from the SARAD and 82 from the psychiatric hospital. The prevalences of S. ...

Nessa população foi descrito o primeiro surto de Staphylococcus aureus associados à comunidade (CA-MRSA). No entanto, a maior parte dos estudos relacionando S. aureus e MRSA a drogadição aborda usuários de substâncias endovenosas. No Brasil, a maior parte de dependentes é usuário de drogas inalatórias, especialmente o crack. Uma parcela destes dependentes tem múltiplas passagens por clínicas de recuperação. Um outro grupo institucionalizado ainda relevante no Brasil são os pacientes com internações de longa permanência em hospitais psiquiátricos. A despeito da reforma psiquiátrica e sua ênfase na desinstitucionalização, aspectos de vulnerabilidade social e abandono por familiares determinam ainda a residência de pacientes em hospitais psiquiátricos. Os dois grupos descritos acima são expostos a diferentes pressões epidemiológicas e estão tanto em maior risco de doença estafilocóccica invasiva quanto em posição estratégica para manutenção e disseminação de isolados. Este estudo teve por por objetivo identificar a prevalência e fatores preditores do carreamento de S. aureus e MRSA em UDI internados no Serviço Hospitalar de Referência de Álcool e Drogas (SARAD) e pacientes residentes no Hospital Psiquiátrico Cantídio de Moura Campos, ambos localizados em Botucatu, SP. Caracterização molecular de isolados de MRSA foi realizada. Foram estuados 220 sujeitos, 138 do SARAD e 82 do ho... (Complete abstract click electronic access below) / Mestre

This is a cross-sectional research and quantitative. The study included 150 internet users, genders, male and female, aged between 17 and 53 years old, students from several graduate courses at the college health, a single campus of a private university, located in São Bernardo do Campo on the São Paulo metropolitan area. The sample was selected by criteria of convenience, but it was considered by quota sampling to better represent the population. The instruments used were the Psychiatric Morbidity Questionnaire for Adults (QMPA) and an additional questionnaire designed to characterize the sample. After collection, the data were statistically treated and released. The results showed the prevalence of mental health in 58% of college Internet users. Among participants who had symptoms of psychiatric morbidity (42%) were the most prevalent symptoms of mood disorder, anxiety, somatization, depression and irritability, symptoms, commonly referred to as minor psychiatric disorders. Were considered heavy users by use the Internet for over 60 hours per month, 55% of Internet users studied. However these symptoms of psychiatric morbidity showed no differentiation between types of users (heavy and light), prevailed in both cases the mental health evaluation. The hours of Internet access were considered one of the signs of pathological Internet use, but insufficient to diagnose the pathological use. The pathological Internet use was present in 57% of Internet users, by using the Internet to the detriment of other aspects of their lives. The symptoms of psychiatric morbidity showed significant positive correlations with the issues on the pathological use of the Internet. These results suggest that the pathological use of the internet reveals itself as a new field of expression of psychiatric morbities known. Thus, the Internet does not appear as a risk factor for mental health of its users. It would be an amplifier, a tool that would facilitate the expression of such pathological behaviors, that come from existing disorders as well as the use of various other social practices, which can become pathological manifestations of different disorders by the individual. / O presente estudo teve como objetivo avaliar a saúde mental de internautas universitários. Trata-se de uma pesquisa com delineamento transversal e quantitativa. Participaram deste estudo 150 usuários de internet, dos gêneros, masculino e feminino, com idade entre 17 e 53 anos, estudantes universitários de diversos cursos de graduação da faculdade de saúde, de um único campus, de uma universidade privada, localizada na cidade de São Bernardo do Campo, na região metropolitana de São Paulo. A amostra foi selecionada por critério de conveniência, porém considerou-se a amostragem por cotas para melhor representatividade da população estudada. Os instrumentos utilizados foram o Questionário de Morbidade Psiquiátrica para Adultos (QMPA) e um questionário complementar desenvolvido para caracterização da amostra. Após coleta, os dados foram lançados e tratados estatisticamente. Os resultados mostraram prevalência de saúde mental em 58% dos internautas universitários. Entre os participantes que apresentaram sintomas de morbidade psiquiátrica (42%) prevaleceram os sintomas de exaltação do humor, ansiedade, somatização, irritabilidade e depressão, sintomas comumente referidos como transtornos psiquiátricos menores. Dos internautas estudados 55% foram considerados usuários pesados por utilizarem a internet acima de 60 horas mensais. A média de horas de acesso à internet apresentou correlação com os sintomas de morbidade psiquiátrica avaliados. Contudo estes sintomas de morbidade psiquiátrica não apresentaram diferenciação entre tipo de usuário (pesado e leve), em ambos os casos prevaleceram a avaliação de saúde mental. As horas de acesso à internet foram consideradas um dos indícios do uso patológico da internet, porém insuficiente para estabelecer qualquer diagnóstico. O uso patológico da internet mostrou-se presente em 57% dos internautas, por utilizarem a internet em detrimento de outros aspectos de suas vidas. Os sintomas de morbidade psiquiátrica apresentaram correlações positivas e significativas com as questões sobre o uso patológico da internet. Os resultados desta pesquisa sugerem que o uso patológico da internet revela-se como um novo campo de expressão de morbidades psiquiátricas já conhecidas. Deste modo, a internet não se mostra como um fator de risco para saúde mental de seus usuários. Ela seria um amplificador, uma ferramenta que facilitaria a expressão de tais comportamentos patológicos, que são provenientes de transtornos já existentes, assim como a utilização de diversas outras práticas sociais, que podem se tornar patológicas pela manifestação de diferentes transtornos do indivíduo.

The term web 2.0 appeared to qualify a second generation of services and communities, in a new interaction and participation environment that includes several languages. With the growth of digital technology accession, some barriers that limited the collaboration in informative contents were overcome and the communication environment becomes an experience exchange local and daily practices.In this scenario, the surfers now have a near relationship in the media processes present in the digital support, in which citizens can express, be more visible and relate from the moment that his produce, post and share any type of content, could be informative or entertainment.The literature review covers the authors such as Ciro Marcondes Filho, José Marques de Melo, Nelson Traquina, Alex Primo, Ana Brambilla, Marcelo Träsel, Raquel Recuero, Polyana Ferrari, Squirra, among others.The research method used is qualitative, through a descriptive exploratory research, like a case study.The instruments for research were the direct observation and the semi-structured interview (or semi-open). The main result is that the collaborate web journalism in the “Portal R7” it is primarily induced by social networks, in specially Facebook and Twitter inspired by call for action like a strategy to call the collaboration.The journalist practices are intrinsically dependent on user’s actions, and the journalist adds to the check practices a new stage related a relationship with the Portal user to assemble and retain the audience, enhancing the cooperation in all production stages / Este estudo procura verificar como ocorre a colaboração dos usuários no conteúdo informativo do Portal R7, a partir da nova configuração da internet, a web 2.0, criada em 2004. O termo web 2.0 surgiu para qualificar uma segunda geração de comunidades e serviços, em um ambiente de interação e participação que engloba diversas linguagens. Com o crescimento da adesão à tecnologia digital, algumas barreiras que limitavam a colaboração nos conteúdos informativos foram superadas e o ambiente comunicacional tornou-se um espaço de intercâmbio para experiências e práticas do cotidiano. Nesse cenário, os internautas passam a ter uma relação mais aproximativa nos processos midiáticos presentes no suporte digital, no qual o cidadão pode se expressar, ter maior visibilidade e se relacionar a partir do momento em que ele produz, publica e compartilha qualquer tipo de conteúdo, seja de caráter informativo ou de entretenimento. A revisão bibliográfica abrangeu autores como Ciro Marcondes Filho, José Marques de Melo, Nelson Traquina, Alex Primo, Ana Brambilla, Marcelo Träsel, Raquel Recuero, Polyana Ferrari, Squirra, entre outros. O método de investigação utilizado é o qualitativo, por meio de uma pesquisa exploratória descritiva, do tipo estudo de caso. Os instrumentos para a investigação foram a observação direta assistemática e a entrevista semiestruturada (ou semiaberta). O principal resultado obtido é que o webjornalismo colaborativo no Portal R7 é prioritariamente induzido pelas redes sociais, especialmente o Facebook e o Twitter, inspirado no “call for action”, como estratégia para chamar à colaboração. As práticas jornalísticas estão intrinsicamente dependentes da ação do usuário, sendo que o jornalista agrega às práticas de checagem uma nova etapa, a de relacionamento com o usuário do Portal, para agregar e fidelizar a audiência, valorizando a colaboração em todas as etapas de produção.

Bakgrund: Heroin är en olaglig narkotikaklassad drog som är starkt beroendeframkallande. Bruket har en negativ inverkan på den fysiska, psykiska och sociala hälsan vilket medför ett komplext vårdbehov. Brukare är utsatta för stigmatisering i samhället. En faktor som kan utgöra hinder för god vård på lika villkor är hälso- och sjukvårdspersonals attityder gentemot patienter de vårdar.  Syfte: Syftet var att belysa hälso- och sjukvårdpersonals attityder gentemot patienter som är eller har varit brukare av heroin. Metod: En litteraturöversikt baserad på tio vetenskapliga artiklar genomfördes enligt Fribergs metod. Artiklarna baserades på kvalitativa och kvantitativa studier samt studier utförda med mixad metod.   Resultat: Resultatet visar på förekomst av positiva och negativa attityder. De negativa attityderna var mer framträdande. Ytterligare framkom en polarisering av attityder inom gruppen hälso- och sjukvårdspersonal. Skillnaden var dock inte knuten till en viss yrkesgrupp utan kopplades till utbildning och erfarenhet av att arbeta med den aktuella patientgruppen. De som arbetade närmast patienterna hade övervägande positiva attityder och vice versa. Diskussion: Resultatet diskuteras utifrån centrala begrepp och idéer av Joyce Travelbee samt hur resultatet står i förhållande till vetenskap och lagtext. Tänkbara anledningar till förekomsten av negativa attityder avhandlas. En  “vi-och-dem"-mentalitet bidrar till hälso- och sjukvårdspersonalens svårigheter att empatisera för patienterna vilket utgör hinder för vårdrelationen. Medvetandegörande, erfarenhet och utbildning belyses som avgörande för möjliggörandet av en förändring. / Background: Heroin is an illicit narcotic drug that is highly addictive. The drug has a negative impact on the physical, mental and social health of the user, which implies complex needs of healthcare. Users are exposed to stigmatization in society. One factor that may constitute barriers to good care on equal terms is the healthcare professionals' attitudes towards patients they care for. Aim: The aim was to highlight attitudes of health personnel towards patients who are or have been users of heroin.  Method: A literature review based upon ten scientific articles was conducted according to Friberg’s method. The articles were based on qualitative and quantitative studies as well as studies performed with mixed method. Results: The result shows the presence of positive and negative attitudes. The negative attitudes were more prominent. Further on a polarization of attitudes within the group of healthcare professionals was revealed. However, the difference was not linked to a certain profession but instead linked to education and experiences of working with the current patient group. Those who worked closest to the patients held predominantly positive attitudes and vice versa. Discussion: The results are discussed on the basis of key concepts and ideas of Travelbee and how the result fits in relation to science and legal texts. Possible reasons for the presence of negative attitudes are discussed. A ‘we-and-them ' mentality contributes to the difficulties of health professionals in empathizing with patients, which precludes the caring relationship. Awareness-raising, experience and education are highlighted as crucial to the facilitation of change.
