In this work, vibration characteristics of high speed rotary bell cup for paint atomizer are numerically investigated. New type of bell cup model is proposed and additional corresponding models with design parameter variations for length and diameter are constructed. Dynamic characteristics, such as natural frequencies and corresponding mode shapes, are studied for each model as a first step. To investigate operation stability, critical speed of rotary bell cup is numerically analyzed based on Campbell diagram and separation margin between operating speed and critical speed is identified. Unbalance vibration responses are also investigated with respect to design parameter variation, operating speed and balancing quality grade of G. Then the proper design guideline for stable operation of high speed rotary bell cup for paint atomizer is suggested.

Recurrent Bell's palsy is a very rare case and have been reported that shows the incidence to be approximately 10 per cent in the Bell's palsy patents. It is generally accepted that facial paralysis caused by compression of the facial nerve by tumor develops slowly and has an unremitting course, however, reported cases have described the rare association of recurrent facial paralysis and intracranial tumor, and the same recovery rate. Usual symptoms of Bell's palsy include subacute facial palsy, hyperacusis on the affected side, postauricular pain on the affected side, altered sensation of taste, and partial trigeminal distribution hypesthesias. Complete resolution of symptoms is usually seen in 2-3months in $75-85\%$ of cases, with $25-35\%$ showing varying degrees of residual effects. We report a case of 4th ipsilateral recurrent Bell's palsy in a 14-year-old women, which was occurred in every winters. We treated her with acupuncture, moxibustion, herbal medication, carbon and silver spike point, and used House-Brackmnn grading system(HBGS) and the Fisch Detailed Evaluation of Facial Symmetry(DEFS) to assess the degree of paralysis in each part of face.

Purpose: The purpose of this study is to report the effect of oriental treatment to Bell's palsy occurred during pregnancy. Methods: We treated 28 year old woman and 31 year old woman who had the Bell's palsy occurred during pregnancy. 2 patients were treated with oriental treatment such as herb medicine and acupuncture therapy. The effects of these treatment was evaluated by Yanagihara's unweighted grading system. Results: As a result, symptoms were remarkably alleviated and Yanagihara score was improved. Conclusion: According to this result, we concluded the oriental treatment could improve pregnant Bell's palsy patient. After this paper, further study and clinical approach based on oriental treatment will be needed about pregnant Bell's palsy patient.

Purpose: This study was aimed to report the effect of oriental treatment on Bell's palsy during pregnancy with Sasang Constitutional method. Methods: 4 patients who had Bell's palsy during pregnancy were treated with Sasang constitutional prescriptions. After treatments we evaluated the effects by House-Brackmann facial nerve grading system. Results: As a result, the clinical symptoms of Bell's palsy during pregnancy were improved. Conclusions: This case studies show that Sasang constitutional method can be effectively used on Bell's palsy during pregnancy. Especially the diagnostic results by using Diagnosis System of Oriental Medicine (DSOM) revealed that some of patients were in a very weak condition. We could apply these results to choose prescription and get good therapeutic effects.

Bell's palsy is an acute peripheral facial paralysis with no detectable cause. Although the prognosis of Bell's palsy is generally good, some patients experience poor recoveries and there is no established treatment for those that do not recover even after receiving the conventional treatment. Here we present two cases of refractory Bell's palsy with facial nerve enhancement in magnetic resonance imaging who showed symptomatic improvement after the late administration of high-dose intravenous methylprednisolone.

Background: Electrophysiologic study accurately predicts the degree of degenerated motor axons but cannot give precise information on the type of injury that occurred in Bell's palsy. Because of these limitation for prognostic prediction in Bell's palsy, we evaluated divergence of electrophysiological time course for the purpose of presuming the type of injury in Bell's palsy. Methods: We did bilateral facial nerve conduction studies in 103 Bell's palsy patients, who visited to Han-Gang sacred heart hospital from 1998 to 2001. We compared the CMAP amplitude of disease site with that of normal site and suggested that decremental CMAP amplitude ratio (percentage) as a degree of denervation of affected facial nerve. Then we demonstrated the time course of denervation percentage. After defining normal range of CMAP amplitude difference from normal control group, we also evaluated if distinct time course of early minimal denervation is present. Results: Our results show that time course of the denervation in early stage of Bell's palsy reflect various injury type such as axonotmesis, neurotmesis or other unidentified type. We cannot identify the distinct time course of early minimal denervation. Conclusions: The time course as well as the maximal value of denervation are the best prognostic guidelines in Bell' s palsy. So repeated serial electrophysiologic test are inevitable to assess prognosis. As an another topic, early minimal denervation for prognostic prediction deserve to be evaluated as a future work up for prognostic prediction.

Objectives : The aim of this study is to investigate the influence of anxiety and depression on motor recovery of acute Bell's palsy to estimate how much psychological factors affect the clinical prognosis. Methods : A total of 20 inpatients with acute unilateral Bell's palsy within 1 week of onset participated in this study. The severity of participants' facial palsy was measured by Yanagihara(Y-system) score, FDI and House-Brackmann scale at the time of 1 week and 3 weeks from the onset. The motor recovery of acute Bell's palsy is defined as ${\Delta}Y$-system during 2 weeks. Beck anxiety scale(BAI) and the center for epidermiologic studies depression scale(CES-D) were adopted to assess anxiety and depression, respectively. Correlation analysis and linear regression analysis were conducted between ${\Delta}Y$-system and prognostic factors including anxiety and depression. Results : Significant associations were found between ${\Delta}Y$-system and depression(CES-D) but no significant associations were found between ${\Delta}Y$-system and other prognostic factors, hypertension, diabetes, postauricular pain, disgeusia, age, degree of initial palsy and anxiety(BAI). And a regression equation with 0.295 for coefficient of determination was obtained. Through this analysis, the ${\Delta}Y$-system can be predicted using regression equation which cover 29.5 % of depression index(CES-D). Conclusion : Depression is a significant clinical prognostic factor on motor recovery of acute Bell's palsy. So, Bell's palsy treatment should be combined with psychological care and support.

Objective: The aims of this study are to find out proper methods to assess Bell's palsy with DITI and to validate the correlation between DITI of acupoints and H-B scale. Methods: 36 Bell's palsy patients and 10 health people were measured. We checked thermal differences between abnormal and normal acupoints sites measured by using DITI and H-B scale. Results: There was no significant thermal difference between abnormal and normal sites. The H-B scale was significantly correlated with thermal differences of ST6 and TE17. Conclusion: DITI was useful for evaluating the severity of Bell's palsy.

The objectives of this study were to evaluate the effect of combined treatments (slightly acidic electrolyzed water (SAEW), ultrasound (US), or mild heat (60℃)) on the growth of Listeria monocytogenes and Salmonella enterica serovar Typhimurium in fresh-cut bell pepper, and the shelf-life and sensory quality (color and texture) were followed during storage at 4℃ and 25℃. An additional 0.65, 1.72, and 2.70 log CFU/g reduction was achieved by heat treatments at 60℃ for 1 min for DW, SAEW, and SAEW+US, respectively. Regardless of the type of pathogen, the combined treatment (SAEW+US+60℃) achieved a significantly (p < 0.05) longer lag time in all treatment groups. This combined treatment also prolonged the shelf-life of bell pepper up to 8 days and 30 h for the storage at 4℃ and 25℃, respectively. There was also no significant difference in the color and hardness of treated (SAEW+US+60℃) bell pepper from that of control during the storage. This new hurdle approach is thus expected to improve the microbial safety of bell peppers during storage and distribution.
