  • Hearing loss caused by exposure to industrial machine noise results in devastating disability that is mostly preventable. And recent researches indicate that the noise may also induce hypertension and cardiovascular disease. In addition the sleep polygraph provides many indicators of sleep disturbance by the noise. In this paper we make an analysis on ball bearing machine noise, a kind of the industrial noise. The analysis of Its power spectrum is based on FFT(Fast Fourier Transform). And then the spectral results of the noise are compared with that of the spectrum for an auditory signal. The signal is measured from the pronunciation of two Koreans. Finally we suggest the most important stratagem to prevent the noise for worker's health and efficiency.

  • Herpes zoster oticus which is called Ramsay Hunt syndrome, geniculate ganglion herpes and otic herpes, is characterized by a viral prodrome with otalgia, vesicular eruptions, facial paralysis, hearing disturbance, tinnitus, vertigo and other symtoms. Among cranial nerves, trigeminal and facial nerves are the most commonly affected in patients with herpes zoster oticus, but on rare occasions 8th, 9th, 10th, 11th, 12th cranial nerves and even the upper cervical nerve are influenced as well.. In general, it has poor prognosis compared with Bell's palsy, leaving permanent facial nerve dysfunction. We report a case of Herpes zoster oticus, which was fully recovered by acupuncture and herbal medication within 12 days. We used $FEMA^{11)}$ and House-Brackmann's grading system to assess the degree of paralysis in each part of face.

  • Magnetic bearing is an attractive device in precision engineering field because of its non-contacting nature and controllability of its dynamic characteristics. This paper provides a method of designing a sliding mode control for an active magnetic hearing(AMB) system which is used to support the elevation axis of a target tracking sight instead of mechanical bearings to eliminate the effect of mechanical friction. In such system, the axis should be levitated and supported within a predetermined air gap while AMB is excited by base motion. Experimental results showed that the sliding mode control is effective in disturbance rejection than conventional PID-control without any additive measurements.

  • Vestibular dysfunction has rarely been reported in MELAS syndrome. A 40-year-old male with long-term diabetes and hearing loss experienced a stroke-like episode with hemisensory disturbance and lactic acidosis. Brain MRI showed temporo-parieto-occipital cortical lesions, and a final diagnosis was made of MELAS syndrome with the mitochondrial 3243A>G mutation. Neuro-otologic evaluations revealed anterior-canal-sparing bilateral impairments of the vestibulo-ocular reflex in the video head impulse test and no caloric paresis. This unique pattern of vestibular dysfunction may aid in diagnosing MELAS syndrome.

After analysis of data obtained, the results of the study summarized as follows; 1) Requested Adequate care Requested Adequate care showed from 5 % to 3% in 1962 and 1984 respectively. In sexes, Requested Adequate in girls (2.8%) more apparent than in boys (2.5%) 2) Eyes i) Weak vision, abnormal refraction of eyes (myopia, hypermetropia and astigmatism), eye diseases (trachoma, others) were found as shown in the Table 2, Figure 3. Weak vision and abnormal refraction of eyes showed from 2 % (Elementary), 5 % ( Secondary) to 4 % (Elementary), 14 % (Secondary) in 1962 and 1984 respectively. In both sexes, the older the age of students the more weak vision and abnormal refraction of eyes had rapidly increased especially in over 15-year old. ii) Eye diseases (trachoma, others) showed from 2% to age of students the more diseases had students. 3) Ear, nose and pharynx Hearing disturbance, ear diseases (otitis mediae, others), nose (empyema, hypertrophy) and pharynx diseases were found as following 1) Hearing disturbance was found from 0.3%(Elementary), 1 %(Secondary) to 0.05 % (Elementary), 0.4 % (Secondary) in 1962 and 1984 respectively, however, recently the older the age of students the more had students. ii) Ear diseases showed from 1.7 % (Elementary) 1.0 % (Secondary) to 0.3 %(Elementary), 0.5%(Secondary) in 1962 and 1984 respectively. iii) In diseases of the nose and pharynx, tonsilitis showed from 2.5% (Elementary), 3.5 % (Secondary) to 1.8 % ( Elementary). 2.5% (Secondary) in 1962 and 1984 respectively. 4) Skin Infectious skin diseases and other skin diseases were found from 1.5% to 0.6% in 1962 am 1984 respectively. 5) Teeth Dental caries (in milk and permanent teeth) and otner oral diseases are shown from 12 % (Elementary), 8%(Secondary) to 75%( Elementary), 25% (Secondary) in 1962 and 1984 respectively. 6) Other defects and diseases A relatively higher morbidity was shown in the tubercular diseases, in anemia, and in heart diseases among the tuberculous diseases, nodular diseases, Pleurisy, heart diseases, anemia, beriberi, hernia, neurasthenia, speech difficulty, mental disorders, bone dysformity, motion difficulty of extremities. In both sexes, tuberculous diseases were found almost equally in both sexes and anemia in girls was more apparent than in boys. Trying to provide more effective health services in schools : i) A better and more effective physical examination should be carried out in each school and prior to the physical examination, the qualified daily observation of children by teacher should be keenly practiced. ii) According to the results of the required annual physical examination the leading cause of morbidity were dental caries, myopia, angina and otitis mediae and fore these diseases follow up should be carried out. iii) For prevention and treatment of diseases and defects health education for students in the classroom as well as to parents is urgently requested.

  • Objective : Surgery for the microvascular decompression is mostly concerned with injury to the cranial nerves or brain stem by cerebellar retraction. Intraopeartive brain stem auditory evoked potentials(BAEPs) has been continuously monitored on surgery to evaluate the extent of injury, recovery of the nerves and prognosis. Methods : Of the 161 cases of CP angle surgery from Feb. 1996 to Apr. 1998, 103 cases were monitored during operation. Thirty five patients who had undergone similar surgery were selected and evaluated ; 23 patients were monitored and 12 were not during surgery. If monitor showed more than 0.5 mSec delay of latency, surgeon was given a warning not to retract brain any more. If more than 1mSec delay, surgeon was informed to stop surgery and wait for the returning of evoked potentials. The level of amplitudes and delay of latencies during the initial stage of operation, opening the dura, insertion of teflon patches, and closing the dura and recovery were then compared. Resuls : Twenty patients were male and 15 were female. Their average age was 50.26 years. Mean amplitude during the initial stage of operation was $0.60{\pm}0.25mV$, at opening the dura $0.56{\pm}0.26$, after teflon patches insertion $0.49{\pm}0.20$, and after closure of dura $0.47{\pm}0.28mV$. Mean latency during the early stage of operation was $6.08{\pm}0.67mSec$, at opening of dura $6.38{\pm}0.55$, insertion of teflon $6.97{\pm}0.59$, and closing the dura $6.17{\pm}0.54$. There was statistical significance in the difference of amplitudes between each procedures, and in the difference of latencies. For the complete recovery of amplitude and latency, it usually took average 5.65 minutes(0-20 min). In monitored group, only one patient required more than 20 minutes to recover and suffered from hearing disturbance after surgery. Others were recovered within 10 minutes without complications. However, 4 out of 12 patients who were not monitored showed hearing disturbance, and 1 patient had temporary facial palsy and dizziness(p=0.000). Conclusion : The results indicate that continuous intraoperative monitoring of BAEPs during CP angle surgery is seen mandatory procedure to prevent operative complications.

  • Background and Objectives With increasing frequency of car accidents, patients of dizziness caused by car accidents are also increasing. Various types of dizziness or vertigo can occur from car accidents depending on different injury mechanisms. Since accurate diagnosis is important for providing proper treatments, we evaluated clinical characteristics related to vestibular function of patients with dizziness caused car accidents. Subjects and Method In this retrospective case review study that runs from January 2011 to March 2013, a total of 82 patients with dizziness following car accident were enrolled consecutively. We analyzed the final diagnosis of dizziness according to different mechanisms of injury during car accident through clinical record review. Patients who developed dizziness within one month of car accident were included, excluding those who had temporal bone fracture and previous history of dizziness. Results Of the different types observed, 36.6% was head injury, 24.4% whiplash injury, 3.7% complex injury, 2.4% others and the rest was unknown. In the final diagnosis, the different types included 36.6% benign paroxysmal positional vertigo (BPPV), 23.2% unclassifiable dizziness, 18.3% cervical vertigo, 7.3% labyrinthine concussion, 3.7% BPPV with labyrinthine concussion and the rest was others. Of the different types of dizziness symptoms, 58.5% was headache, 45.1% was audiologic symptoms, and others included earfullness, tinnitus and hearing disturbance. Tinitogram and pure tone audiogram results show that 2.9% (27 people) of patients have tinnitus and 7.3% (6 people) have hearing disturbance. Conclusion An accurate diagnosis and timely management would be very important in forming a proper approach for post traumatic vertigo patients.
