The purpose of this study was to investigate the treatment pattern of patients with neuropathic pain (NeP) in Korea through computerized database of Health Insurance Review and Assessment Service (HIRAS) over three years' period from 2003 to 2005. The results showed that the numbers of treatment visits were the highest for diabetic neuropathy (DN), followed by postherpetic neuralgia (PHN) and trigeminal neuralgia (TN) in order. Top 3 specialties for treatment visits due to NeP conditions were neurology, neurosurgery and anesthesiology. While cost of a treatment visit was higher in anesthesiology and emergency clinics compared to other clinics, there was a tendency to increase costs for visits to clinics of rehabilitation medicine and family medicine over the three years. Cost of dental visits was relatively high for TN, atypical facial pain (AFP) and atypical odontalgia (AO). Surgeries frequently applied to patients with NeP were sympathetic plexus or ganglion block, block of peripheral branch of spinal nerve and cranial nerve or its peripheral branch block. Most common prescribed medication were anticonvulsants, anti-inflammatory analgesics and anti-psychotic drugs while anti-inflammatory analgesics were overwhelmingly frequently prescribed for AO and glossodynia. Based on the results of this study, NeP disorders more relevant to dentists were AO, TN and AFP, TN of which seems to be the most important in terms of patients' number and cost for treatment visits. This indicates that dentists, especially oral medicine specialists should actively participate in management of TN, AO and AFP and share relevant information with patients and community.

The descriptive epidemiology of specific neuropathic pain disorders has not been well-des-cribed, although the burden of neuropathic pain is well recognized. The true incidence of neuro-pathic pain disorder is unknown, but it is believed to be under diagnosed and treated inade-quately, despite the development of various diagnostic system. The purpose of this study was to report the epidemiology of specific neuropathic pain as managed by all kinds of hospital in Korea. A descriptive analysis of the epidemiology of prevalent trigeminal neuralgia(TN)(n-=77,053 27,6%), atypical facial pain(AFP)(n=12,382 4.4%), glossopharyngeal neuralgia(GN)-(n=1,319 0.5%), post-herpetic neuralgia(PHN)-(n=84,598 30.3%), diabetic neuropathy(DN)-(n=85,989 30.8%), atypical odontalgia(AO)-(n=16,001 5.7%) and glossodynia(GD)(n=2,133 0.8%) and treatment departments and treatment durations from computerized Health Insurance Review and Assessment Service(HIRA) of Korea: January 2003 to December 2005, are reported with rates increasing over time for PHN and DN and decreasing for the other neuropathic pain disorders. Most patients were treated at private clinic record for 57.6-72.8% of patients except OA for 10.3%. The percentage of Dept of dentistry for outpatients was 3.2% for TN, 34.7% for AO and 15.4% for GD. Other neuropathic pain patients visited nearly medical clinic.

This study investigated 2,088 economically active workers aged 20 to 65 years selected from the sixth Korea National Health and Nutrition Examination Survey to evaluate the relationship between chronic diseases and oral health behaviors among economic workers and examine the risk factors for oral diseases. The results of the study were as follows. Dental caries were related to subjective oral health status, toothache experience, orthodontic treatment experience, chewing problems, speaking problems, oral examination, and dental clinic use. Periodontal disease was associated with oral health status, toothache experience, orthodontic experience, and chewing and speaking problems. The risk factors for chronic diseases and oral health behavior were as follows. Hypertension, 1.37 times; obesity, 1.48 times; diabetes, 1.5 times; low HDL-cholesterol, 1.31 times; hepatitis A antibody, 1.53 times higher. Health status was found to be 1.70 times higher in dental caries and 2.10 times higher in periodontal disease. The tooth experience was 1.30 times higher in dental caries and 1.35 times higher in periodontal disease. Problems chewing were 1.76 times for dental caries and 1.78 times for periodontal disease. The possibility of dental caries and periodontal disease was 1.44 times higher. Smokers were 1.61 times more likely to have dental caries and 1.63 times more likely to have periodontal disease. These results suggest that periodontal diseases increase the risk of chronic diseases and oral health behavior increases the risk of dental caries and periodontal disease. Although dental caries seem to have a lower risk of becoming a chronic disease if only oral health care is good, it is considered that both chronic disease and oral health care are important for periodontal disease.

코카인은 열대지방에 광범위하게 분포되어 있는 Erythroxylon나무의 잎에 존재하고 있는 알칼로이드이다. 1536년 Pizarro가 스페인 침공을 마친 후 귀국하면서 유럽에 소개되었으며 Alfred Niemann에 의해서 1853년 처음으로 코카잎에서 추출되었고 "cocaine"이라고 명명되었다. 코카인은 황홀감을 일으킬 뿐 아니라 감기, 피부병, 천식, 류마치즘, 후두염 및 치통에도 효과가 좋다고 알려졌었고 국소마취효능이 좋아 아직까지도 안과 영역에서 가끔 사용되고 있다. 그러나 코카인은 인류가 알고 있는 물질중 가장 강화(reinforcement)효과가 강한 물질이기에 현재 법적으로 그 사용이 국소마취제 이외에는 금지되어 있으나 황홀감을 얻기위한 불법적인 사용이 크게 늘어있는 형편이다.늘어있는 형편이다.

This paper described the characteristic of vibration in wind turbine system including gearbox housing, gear drive, blade, generator. Especially, in planetary gear set, planet gears are supported by flexible pin. So, in planet gear, to consider not only torsional movement but also lateral movement. And include housing movement, because wind turbine system is supported by mount. To find out the characteristic of vibration, take the excitation source and study campbell diagram in operating range. Results of campbell diagram, resonances are occurred at 81.2HZ, 104.7Hz by 2nd tooth passing frequency. And resonance are also occurred at 264.5HZ, 377Hz, 424.6Hz by 3th tooth passing frequency. From the result, take vibration reduced measures.

Objectives: Patients with nonodotogenic toothache are increasing in numbers. However, there is no reliable treatment guide in both conventional & complementary medicine. Also, there are not much clinical case of patients with nonodotogenic toothache in oriental medical field. We investigated effect of using craniosacral therapy and acupuncturing suboocitptal muscle on patient with nonodotogenic toothache. Methods: 72-year old female patient with nonodotogenic toothache was treated with using craniosacral therapy and acupuncturing suboocciptal muscle. Results: We had a satisfactory result with using craniosacral therapy and acupuncturing suboocitptal muscle. The patient's VAS grade improved to 1(Rt.), 5(Lt.). Conclusions: We reach a conclusion using craniosacral therapy and acupuncturing suboocitptal muscle improve patient with nonodotogenic toothache. And more study about this disease is needed.

This paper estimated the stability of centrifuge as its rotating speed compared with the natural frequency of cylinder and screw by finite element analysis. It shows that the one of exciting causes is the tooth passing frequency of input and output parts by the periodic characteristics of transmission error due to an planetary gear having three stages. Also, it proposed the critical speed of cylinder and screw by the Campbell diagram.

아세트아미노펜(파라세타몰)은 p-aminophenol 유도체로서 (그림 1) 두통, 치통, 신경통 등의 통증에 널리 사용되는 해열진통제인데 아스피린과 같은 정도의 해열 진통 효과를 나타내며, 이것은 중추신경계의 체온조절 중추에 작용하여 피부혈관을 확장함으로써 열의 확산을 증가시키는 해열작용과 시상 및 대뇌피질에의 통각역치를 높여 진통작용을 하는 것으로 추정 된다. 아세트아미노펜은 백색의 결정 또는 결성성 가루로 물에 조금 녹고 메탄올 또는 에탄올에 잘 녹으며 수산화나트륨 시액에 녹고 에텔에는 매우 녹기 어렵다 (표1). 대한약전에서는 정제가, 미국약전에는 캅셀제, 좌제, 경구현탁액제, 발포성 건조시럽, 정제 등이 수재되어 있고, 세계 각국에서 OTC 제품으로 1정당 160mg의 츄잉정까지 판매되고 있다. 그러나, 시판되고 있는 정제등은 붕해되어 용출되는데 오랜시간이 소요되어 대한약전에는 약 30분간에 80%이상의 용출기준이 설정되어 있으며, 독특한 쓴맛 때문에 microencapsulation 한 제피세립을 사용하고 있으나 역시 1 정당 300mg 이상의 확산정이나 속용정은 존재하지 않는다. 이것을 개선하기 위하여 붕해속도가 빠르고 특히 진통효과가 빠르며 물없이 구강내에서 간편히 녹여 복용하거나 또는 씹어서 또는 물과 함께 복용할 수 도 있는 $\ulcorner$알카펜$\lrcorner$ 속용정을 개발하게 되었다 (그림2).
