For the purpose of presenting the basic data for the establishment of control measures on the long-term noise exposed workers, this study was carried or on the relationship between personal noise exposed dose and hearing loss on the 67 male workers whose hearing threshold had exceeded 40dB in 4,000Hz, from 1990 to 1992. Conclusively, the level of hearing loss was significantly related to personal noise exposed dose which was measured by the personal noise dosemeter was more efficient rather than the noise level of workplace for the evaluating the long-term change of hearing acuity. And although in the case of not-diagnosed as noise induced hearing loss, it was suspected that the active control programs such as improvement of noisy environment or early transfer to proper workplace were needed on the workers who exposed with over 90dB in personal noise exposed dose.

Mycoplasma pneumoniae is known to be a common respiratory pathogen in children and adolescents. It rarely causes neurologic complications, such as meningitis, encephalitis and cerebellar ataxia, in some patients as extrapulmonary manifestations. Neurologic symptoms, such as impairment of consciousness, seizure and paralysis, in the early stage. We report a case of lobar pneumoia caused by M. pneumoniae which was complicated with status epilepticus and encephalopathy.
