A microprocessor-based real-time digital vibrotactile vocoder system has been developed to train the deaf and for artificial
hearing research. The system is composed of a microcomputer module with a digital signal processor interface units and an
attenuator/driver circuit. Live or digitised (stored or synthetic) speech is presented to the skin spectrally through a belt
housing eight or 16 vibrators. Speech is processed in real time using a fast Fourier transform. The system is also capable
of presenting any arbitrary spatiotemporal pattern on the skin for artificial hearing experiments. A preliminary experiment
with a deaf subject indicates that the system is potentially an effective device for artificial hearing. 相似文献

BackgroundProspective cohort studies have provided useful knowledge about the natural history of asthma. However, most of the studies are conducted in western countries but the course of the disease and long-term outcomes may differ between countries due to environmental and cultural factors.ObjectiveThe aim of this study is to describe the long-term outcomes of childhood asthma, with data from a follow-up study of at least 10 years, in western Anatolia, Turkey.MethodsFifty-two patients diagnosed with persistent allergic asthma participated in the study. The patient's demographics, findings on admission, age at onset of disease, time of diagnosis, history of other allergic conditions, history of parental asthma and allergic disorders, presence of pharmacotherapy and immunotherapy were obtained from patients’ records. The factors influencing remission at the end of 10 years follow-up were evaluated.ResultsA total of 20 patients (38.5%) were on remission at the end of 10 years. The type of allergen, multi-allergen sensitivity, eosinophilia and elevated serum immunoglobulin E on admission, accompanying allergic disorders and atopy in parents, and allergen immunotherapy did not affect the remission rate (p > 0.05).ConclusionChildhood persistent asthma is not a homogeneous clinical entity but high clinical remission rates are obtained in western Anatolia. There is no significant predictor of clinical remission in long term follow-up. Prospective studies should be performed in larger asthmatic populations to obtain further data about the natural course of childhood asthma. 相似文献

The organization of sports at the national level has seldom been included in scientific discussions of sports injury prevention. The aim of this study was to develop a model for organization of sports that supports prevention of overuse injuries. The quality function deployment technique was applied in seminars over a two‐season period to develop a national organizational structure for athletics in Sweden that facilitates prevention of overuse injuries. Three central features of the resulting model for organization of sports at the national level are (a) diminishment of the organizational hierarchy: participatory safety policy design is introduced through annual meetings where actors from different sectors of the sporting community discuss training, injury prevention, and sports safety policy; (b) introduction of a safety surveillance system: a ubiquitous system for routine collection of injury and illness data; and (c) an open forum for discussion of safety issues: maintenance of a safety forum for participants from different sectors of the sport. A nonhierarchical model for organization of sports at the national level – facilitated by modern information technology – adapted for the prevention of overuse injuries has been developed. Further research is warranted to evaluate the new organizational model in prospective effectiveness studies. 相似文献

Culture‐based contributors play a role in eating disorders (EDs). Here, we present one such factor that may play a role in triggering ED's in adolescents: Fasting during the holy period of Ramadan. Ramadan is the Islamic month of fasting, in which participating Muslims refrain from eating, drinking, and smoking, which starts from dawn lasting until sunset. For the past 2 years, we have noticed an increase in patients with disordered eating patterns that have applied to Hacettepe University, Division of Adolescent Medicine during or shortly after Ramadan. We document six of these patients, three of which were diagnosed with an ED and three that did not meet full criteria. We argue that the possible effects of a drastic change in ones diet such as that which occurs during Ramadan, play an important role in triggering ED's in adolescents with a predisposition or may exacerbate an eating pathology. © 2014 Wiley Periodicals, Inc.
