Realtime telemedicine

Telemedicine conducted via prerecorded interaction is more convenient than that using realtime interaction. On the other hand, a realtime consultation allows an immediate result to be obtained and there is likely to be a strong educational component for the remote practitioner. The use of the telephone is under-rated in telemedicine. Telephones have been used in outpatient follow-up, mental health, help lines and support groups. Telephones (fixed and mobile) have also been used for data transfer (e.g. for transmission of electrocardiograms). Realtime transfer of still images has been used in telepathology for many years, and more recently for rapid assessment of injuries. Realtime transfer of video images has been widely explored, perhaps most successfully in telepsychiatry. Some realtime telemedicine applications have been taken up with enthusiasm, even if formal evidence of cost-effectiveness may be lacking. Teleradiology and telepsychiatry are two examples where widespread adoption is beginning to occur. Other forms of realtime telemedicine represent 'niche' applications. That is, they appear to be both successful and sustainable in the centres where they were pioneered, but have not been adopted elsewhere. Teledialysis and teleoncology are examples of this type. The patchy diffusion of telemedicine is something that is not yet well understood.

Unsafe driving behaviour and four wheel drive vehicles: observational study

Objective To assess the level of compliance with the new law in the United Kingdom mandating penalties for rising a hand held mobile phone while driving, to compare compliance with this law with the one on the use of seat belts, and to compare compliance with these laws between drivers of four wheel drive vehicles and drivers of normal cars. Design Observational study with two phases-one within the grace period, the other starting one week after penalties were imposed on drivers using such telephones. Setting Three busy sites in London. Participants Drivers of 38 182 normal cars and 2944 four wheel drive vehicles. Main outcome measures Proportions of drivers seen to be using hand held mobile phones and not using seat belts. Results Drivers of four wheel drive vehicles were more likely than drivers of other cars to be seen using hand held mobile phones (8.2% v 2.0%) and not complying with the law on seat belts (19.5% v 15.0%). Levels of non-compliance with both laws were slightly higher in the penalty phase of observation, and breaking one law was associated with increased likelihood of breaking the other. Conclusions The level of non-compliance with the law on the use of hand held mobile phones by drivers in London is high, as is non-compliance with the law on seat belts. Drivers of four wheel drive vehicles were four times more likely than drivers of other cars to be seen using hand held mobile phones and slightly more likely not to comply with the law on seat belts.

ANÁLISE DAS PRÁTICAS SOCIAIS DA IGREJA COMUNIDADE EVANGÉLICA DE MARINGÁ, À LUZ DA PRÁXIS RELIGIOSA.

A pesquisa analisa as práticas sociais da Igreja Comunidade Evangélica de Maringá, localizada no Estado do Paraná, à luz da Práxis Religiosa. Esta Igreja tem se destacado por suas atividades sociais na cidade onde está sediada. Foi fundada em 1989, por Irene Ribarolli Pereira da Silva, ex-integrante da Igreja Metodista de Maringá. Após deixar a Igreja Metodista, foi ordenada pastora e acumulou também, a função de presidente da nova Igreja. Adotou o neopentecostalismo na formação da nova Igreja, com ênfase na batalha espiritual. São comedidos nos pedidos de dízimos e ofertas e, contrários a entrevista com demônios, devido à exposição dos fiéis que, são em sua sede, predominantemente oriundos da classe média. Ao contrário das igrejas neopentecostais que, privilegiam as multidões mas não prezam pelo contato individual com os fieis, está igreja, valoriza e facilita o contato dos membros com seus pastores e líderes. Para isso disponibiliza publicamente os ministérios da Igreja, com nome e telefone dos pastores e líderes, inclusive o telefone da presidente, para contato pelos fiéis. Em função das práticas sociais realizadas na cidade, no ano de 2003, criaram a Organização Reviver. Essa organização foi criada para expandir e melhorar as atividades da Igreja e, posteriormente foi declarada de utilidade pública, através de um projeto de lei, da Câmara de Vereadores da cidade. Ao analisar suas práticas sociais, serão confrontados as teorias e discursos desta igreja, com suas realizações, para avaliar se existe em seu meio, reflexão, diálogo, percepção da realidade e necessidade caracterizando Práxis, que visa transformação e libertação, ou se o que está por trás, destas atividades é somente um proselitismo disfarçado, ou mero assistencialismo, ou seja, apenas práticas, sem práxis.

TELEFONE CELULAR: A nova mídia de massa a serviço da publicidade segmentada.

Ao final do ano de 2004 o Brasil atingiu o número de mais de 50 milhões de aparelhos celulares, ultrapassando inclusive o número de telefones fixos. No mesmo período, as operadoras de telefonia móvel lançaram o sinal de televisão para serem recebidos nestes aparelhos, que são pessoais e portáteis. O objetivo deste trabalho é verificar se em virtude deste crescimento na base de usuários e da alta tecnologia o aparelho de telefone celular tem potencial como mídia publicitária, sendo capaz de segmentar suas mensagens de acordo com o perfil dos clientes.

Signal processing in a loudspeaking telephone

One of the major problems associated with communication via a loudspeaking telephone (LST) is that, using analogue processing, duplex transmission is limited to low-loss lines and produces a low acoustic output. An architectural for an instrument has been developed and tested, which uses digital signal processing to provide duplex transmission between a LST and a telopnone handset over most of the B.T. network. Digital adaptive-filters are used in the duplex LST to cancel coupling between the loudspeaker and microphone, and across the transmit to receive paths of the 2-to-4-wire converter. Normal movement of a person in the acoustic path causes a loss of stability by increasing the level of coupling from the loudspeaker to the microphone, since there is a lag associated the adaptive filters learning about a non-stationary path, Control of the loop stability and the level of sidetone heard by the hadset user is by a microprocessoe, which continually monitors the system and regulates the gain. The result is a system which offers the best compromise available based on a set of measured parameters.A theory has been developed which gives the loop stability requirements based on the error between the parameters of the filter and those of the unknown path. The programme to develope a low-cost adaptive filter in LST produced a low-cost adaptive filter in LST produced a unique architecture which has a number of features not available in any similar system. These include automatic compensation for the rate of adaptation over a 36 dB range of output level, , 4 rates of adaptation (with a maximum of 465 dB/s), plus the ability to cascade up to 4 filters without loss o performance. A complex story has been developed to determine the adptation which can be achieved using finite-precision arithmatic. This enabled the development of an architecture which distributed the normalisation required to achieve optimum rate of adaptation over the useful input range. Comparison of theory and measurement for the adaptive filter show very close agreement. A single experimental LST was built and tested on connections to hanset telephones over the BT network. The LST demonstrated that duplex transmission was feasible using signal processing and produced a more comfortable means of communication beween people than methods emplying deep voice-switching to regulate the local-loop gain. Although, with the current level of processing power, it is not a panacea and attention must be directed toward the physical acoustic isolation between loudspeaker and microphone.
