25. UM FRAMEWORK PARA PROVISÃO DE QOS EM REDES MÓVEIS SEM FIO / A FRAMEWORK FOR QOS PROVISIONING IN WIRELESS MOBILE NETWORKS
In the last decades, increasing interest has been observed in technologies related to wireless mobile communication environments. Great part of such interest follows the growth in the telecommunications industry, more specifically of cellular mobile telephony systems. Users are quickly absorbing these technologies and generating new necessities, such as the

27. REAL OPTIONS APPLICATIONS IN THE PRIVATIZATION OF THE BRAZILIAN TELECOMMUNICATIONS INDUSTRY : THE EMBRATEL CASE / ABORDAGEM POR OPÇÕES REAIS NA PRIVATIZAÇÃO DO SETOR DE TELECOMUNICAÇÕES: O CASO DA EMBRATEL / ABORDAJE POR OPCIONES REALES EN LA PRIVATIZACIÓN DEL SECTOR DE TELECOMUNICACIONES: EL CASO DE LA EMBRATEL
En la evaluación de proyectos de inversiones, tales como la construcción de una fábrica o la ampliación de una red de telecomunicaciones, comúnmente se utilizan metodologías de flujos de caja descontados, a pesar de sus conocidas limitaciones que produzen resultados menos consistentes. Tales limitaciones pueden ser aceptables cuando el objetivo es úni

30. Cancer morbidity among workers in the telecommunications industry.
A retrospective cohort study of 2918 workers in the telecommunications industry in Sweden recorded the cancer morbidity for the period 1958-79. Cases of cancer were collected from the Swedish Cancer Registry for this period and information on work characteristics was collected for the entire period of employment. The total cancer morbidity was as expected. T

31. Increased incidence of malignant melanoma of the skin in workers in a telecommunications industry.
In 1982 physicians at a hospital melanoma clinic in Montreal noticed that among their patients there had been seven men working in a single telecommunications company. This raised suspicions that working in that industry might be associated with development of malignant melanoma of the skin (MMS). A preliminary gross comparison with general population rates

32. Voice-processing technologies--their application in telecommunications.
As the telecommunications industry evolves over the next decade to provide the products and services that people will desire, several key technologies will become commonplace. Two of these, automatic speech recognition and text-to-speech synthesis, will provide users with more freedom on when, where, and how they access information. While these technologies

33. Magnitude and distribution of trunk stresses in telecommunications engineers.
The incidence of back injuries has been shown to be greater in occupations as heavy manual work than light manual work. To plan a programme aimed at reducing the incidence of back injuries in industry those workers at high risk of incurring handling accidents and back injuries need to be identified and a knowledge of the specific occupational factors causing

34. Pattern of accident distribution in the telecommunications industry.
Examination of the accident records from the telecommunication industry covering some 100 000 engineers over a 12-month period showed that 25% of accidents resulting in more than three days' sick leave gave rise to back injuries. Handling accidents and falls accounted for 65% of three-day-plus accidents; handling accidents alone gave rise to 65% of back inju

35. Serious Technology Assessment for Health Care Information Technology
United States health care is engaged in an ambitious project to make its clinical and administrative records “100% electronic.” Substantial benefits are expected in both clinical care delivery and medical research (especially for public health surveillance and outcomes/effectiveness studies). Substantial costs also potentially accrue, beyond the la

36. Malignant melanoma of the skin among workers in a telecommunications industry: mortality study 1976-83.
An incidence study of malignant melanoma of the skin (MMS), conducted previously among the workers of four plants of a large telecommunications industry located in Montreal, Canada, showed a standardised incidence ratio of 2.7 (95% confidence interval (95% CI) 1.3-5.02) for the years 1976 to 1983. To describe more precisely the magnitude of the problem a mor
