Accommodation management system using mobile devices

Os dispositivos móveis são pessoais, intransmissíveis e cada vez mais utilizados, tornando-se assim numa boa ferramenta para a realização de um conjunto de serviços na indústria hoteleira. Entre esses serviços que necessitam da identificação pessoal, encontram-se a possibilidade do cliente reservar um quarto ou utilizar o serviço de quartos. Atualmente é muito utilizado, nos locais de alojamento, um smart card que possibilite ao cliente ter acesso a alguns dos serviços disponíveis. O objetivo deste documento é apresentar uma alternativa ao sistema de cartões, utilizando para o efeito, dispositivos móveis. De modo a garantir a segurança e uma utilização semelhante ao sistema de cartões existentes foi utilizada a tecnologia NFC (Near Field Communication) que, ao permitir o modo de emulação de cartão, facilita a transação do sistema de smart card existente, para o da utilização de dispositivos móveis na realização das mesmas funções. Mais concretamente, será abordada a utilização de smartphones para o processo de abertura de portas. Para que exista uma melhor compreensão e para que haja um conhecimento das suas capacidades e limites foram estudados casos de uso da tecnologia NFC. Este documento apresenta ainda os processos de desenvolvimento de uma aplicação nativa para o sistema operativo Android, cujo objetivo é proporcionar ao cliente de um local de alojamento um novo modo de acesso ao quarto, utilizando a tecnologia NFC. Para além desta funcionalidade a aplicação permite ainda ao utilizador fazer reservas, fazer o check-in, fazer o check-out entre outras. Posteriormente serão apresentadas as conclusões e possíveis trabalhos futuros.

The BCD transient recorder revisited: firmware for the ISA-to-USB bridging card and software for the graphical user interface

This report describes recent updates to the custom-built data-acquisition hardware operated by the Center for Hypersonics. In 2006, an ISA-to-USB bridging card was developed as part of Luke Hillyard's final-year thesis. This card allows the hardware to be connected to any recent personal computers via a (USB or RS232) serial port and it provides a number of simple text-based commands for control of the hardware. A graphical user interface program was also updated to help the experimenter manage the data acquisition functions. Sampled data is stored in text files that have been compressed with the gzip for mat. To simplify the later archiving or transport of the data, all files specific to a shot are stored in a single directory. This includes a text file for the run description, the signal configuration file and the individual sampled-data files, one for each signal that was recorded.

The Modified Card Sorting Test: Test-retest stability and relationships with demographic variables in a healthy older adult sample

Objectives. To investigate the test-retest stability of a standardized version of Nelson's (1976) Modified Card Sorting Test (MCST) and its relationships with demographic variables in a sample of healthy older adults. Design. A standard card order and administration were devised for the MCST and administered to participants at an initial assessment, and again at a second session conducted a minimum of six months later in order to examine its test-retest stability. Participants were also administered the WAIS-R at initial assessment in order to provide a measure of psychometric intelligence. Methods. Thirty-six (24 female, 12 male) healthy older adults aged 52 to 77 years with mean education 12.42 years (SD = 3.53) completed the MCST on two occasions approximately 7.5 months (SD = 1.61) apart. Stability coefficients and test-retest differences were calculated for the range of scores. The effect of gender on MCST performance was examined. Correlations between MCST scores and age, education and WAIS-R IQs were also determined. Results. Stability coefficients ranged from .26 for the percent perseverative errors measure to .49 for the failure to maintain set measure. Several measures were significantly correlated with age, education and WAIS-R IQs, although no effect of gender on MCST performance was found. Conclusions. None of the stability coefficients reached the level required for clinical decision making. The results indicate that participants' age, education, and intelligence need to be considered when interpreting MCST performance. Normative studies of MCST performance as well as further studies with patients with executive dysfunction are needed.

Executive dysfunction in children and adolescents with temporal lobe epilepsy: Is the Wisconsin Card Sorting Test enough?

The Wisconsin Card Sorting Test (WCST) is the gold standard in the evaluation of executive dysfunction (ED) in patients with temporal lobe epilepsy (TLE). We evaluated 35 children with TLE and 25 healthy controls with the WCST and with a more comprehensive battery. Among the children with TLE, 77.14% showed impairment on the WCST. On other tests (Wechsler Intelligence Scale for Children-Digit Forward, Matching Familiar Figures Test, Trail Making Test, Word Fluency, Finger Windows, and Number-Letter Memory), impairment was demonstrated in 94.29%. The authors concluded that the WCST is a good paradigm to measure executive impairment in children with TLE: however, it may be not enough. Evaluation performed only with the WCST not only underestimated the number of patients with ED, but also missed relevant information regarding the type of ED. (C) 2009 Elsevier Inc.

Card sorts: Constructivist assessment tools

In a changing employment climate and with the growth of demand for careers guidance at all stages of life, careers guidance practice has moved from its positivist world view, with the counsellor as expert and client as passive responder, to more holistic 'constructivist' approaches. In essence, these approaches view the career as a holistic concept in which work and personal life are inextricably intertwined, and individuals are experts in their own lives, actively constructing their careers. The first to fully explore the constructivist approach, this book: provides a theoretical background to constructivism; outlines a range of constructivist approaches to career counselling; and gives examples of the practical application of constructivism. Essential for anyone involved in career guidance wishing to learn more about this vital new approach, this book combines theory with practicable guidance, and represents a new direction for career counselling.

Projeto de implementa????o das cirurgias card??acas no estado do Rio de Janeiro

As estat??sticas revelam a grande demanda reprimida de cirurgias card??acas no Estado do Rio de janeiro (dados de 1996). A conseq????ncia desta restri????o, tem sido um grande n??mero de mortes prematuras, em rela????o ao esperado para o tipo de patologia e tecnologia dispon??vel. Os pacientes que sobrevivem apresentam uma qualidade de vida muito aqu??m daquela que a medicina atual poderia lhes oferecer. Com a iniciativa, a efici??ncia de todo o processo passou a ser avaliada por instrumentos de coleta de dados que permitiram o dimensionamento dos custos previstos no setor e o aumento do n??mero de cirurgias no Estado do Rio de Janeiro, resultando na redu????o da mortalidade de pacientes com cardiopatias

Grupo informativo multidisciplinar em pr??-operat??rio de cirurgia card??aca: a informa????o e a multidisciplinariedade no hospital terci??rio como contribui????o ?? qualidade e ?? humaniza????o no atendimento p??blico de sa??de

A informa????o, atrav??s da Educa????o em sa??de, ?? elemento b??sico para que o cidad??o possa ser participante ativo do processo de busca de maior qualidade de vida, atrav??s do tratamento oferecido. Entretanto, a dificuldade de acesso ao sistema, a falta de vagas e o tempo de espera por uma cirurgia card??aca s??o fatores t??o emergenciais no setor, que o direito ?? um sistema de transmiss??o sistem??tica de informa????o sobre o tratamento nem sempre ?? levado em conta no pr??-operat??rio. Portanto, na busca de um atendimento mais humanizado ao paciente e seus familiares, torna-se importante n??o perder de vista que o cidad??o que procura o hospital traz uma complexidade que alia a doen??a a uma s??rie de vari??veis a serem vistas al??m do lado cl??nico, o que demonstra a necessidade de uma proposta multidisciplinar que possa oferecer informa????es sobre o processo a ser vivenciado no pr?? e p??s-cir??rgico, de forma a oferecer um tratamento ainda melhor

Age effects on EEG correlates of the Wisconsin card sorting test

Body and brain undergo several changes with aging. One of the domains in which these changes are more remarkable relates with cognitive performance. In the present work, electroencephalogram (EEG) markers (power spectral density and spectral coherence) of age-related cognitive decline were sought whilst the subjects performed the Wisconsin Card Sorting Test (WCST). Considering the expected age-related cognitive deficits, WCST was applied to young, mid-age and elderly participants, and the theta and alpha frequency bands were analyzed. From the results herein presented, higher theta and alpha power were found to be associated with a good performance in the WCST of younger subjects. Additionally, higher theta and alpha coherence were also associated with good performance and were shown to decline with age and a decrease in alpha peak frequency seems to be associated with aging. Additionally, inter-hemispheric long-range coherences and parietal theta power were identified as age-independent EEG correlates of cognitive performance. In summary, these data reveals age-dependent as well as age-independent EEG correlates of cognitive performance that contribute to the understanding of brain aging and related cognitive deficits.

Estudo da Mecânica Cardíaca pelo Speckle Tracking

Speckles, ou marcadores naturais do miocárdio, originam se da interferência construtiva e destrutiva do feixe de ultrassom que incide sobre os tecidos, podem fornecer um diagnóstico precoce das alterações miocárdicas e atuar na predição de certos eventos cardíacos. Devido à sua relativa estabilidade temporal, os speckles podem ser rastreados durante o ciclo cardíaco por software dedicados, promovendo a análise da função sistólica e diastólica. São identificados tanto pela escala de cinza da ecocardiografia 2D convencional quanto pela ecocardiografia 3D, sendo independentes do ângulo de incidência do ultrassom, permitindo assim a avaliação da mecânica cardíaca nos três planos espaciais: longitudinal, circunferencial e radial. O objetivo do presente artigo é discutir o papel e o significado da deformação cardíaca obtida por meio do speckle tracking durante a avaliação da fisiologia cardíaca, e discutir as aplicações clínicas desta tecnologia ecocardiográfica inovadora.

Long-term Forecasting of Frame Alignment Losses for Circuit Emulation Implementation

The article provides a method for long-term forecast of frame alignment losses based on the bit-error rate monitoring for structure-agnostic circuit emulation service over Ethernet in a mobile backhaul network. The developed method with corresponding algorithm allows to detect instants of probable frame alignment losses in a long term perspective in order to give engineering personnel extra time to take some measures aimed at losses prevention. Moreover, long-term forecast of frame alignment losses allows to make a decision about the volume of TDM data encapsulated into a circuit emulation frame in order to increase utilization of the emulated circuit. The developed long-term forecast method formalized with the corresponding algorithm is recognized as cognitive and can act as a part of network predictive monitoring system.
