Recently, interest of polymer light-emitting diode (PLED) fabricated from conjugated polymer has augmented because PLED has advantage property that is well-suited to flexible lighting and solution processed device. In this presentation, we suggest a new polymer host based on phenanthrene, poly(9-(3-Vinyl-phenyl)-phenanthrene) (PVPP). It can be easily synthesized through simple synthetic methods which are Suzuki and Wittig reactions. From NMR data, vinyl group protons were disappeared and aromatic protons showed broad proton peaks because of polymer characteristics. PVPP film can be obtained from spin coating with solution used by common solvent. It exhibited PL maximum value of 381nm and broad PL spectrum of 70nm FWHM value. Energy transfer smoothly occurred when the three dopants for green, red and yellow were used in PVPP.

Objectives : This study was to investigate the effectiveness of Bee Venom Pharmacopuncture complex therapy on peripheral facial paralysis. Methods : We investigated 30 cases of patients with Peripheral Facial Paralysis, and devided patients into two groups : We treated one group by complex oriental medical treatment with Bee Venom Pharmacopuncture therapy, and did the other group by complex oriental medical treatment without Bee Venom pharmacopuncture therapy. To investigate the effectiveness of treatment applied for two groups, we used Gross Grading System of House-Brackmann, Yanagihara’s Unweighed Grading System at baseline, 3 weeks and final. Results : 1. Male, Female is same ratio in distribution of sex, the number of left side is more than that of right side in distribution of lesion, the average age is 49.33. 2. Pain back of the ear showed the highest frequency among Bell’s palsy related symptoms at onset, the overwork was a major cause of Bell’s palsy in distribution of cause. 3. As a result of evaluation by using Gross Grading System of House-Brackmann, Yanagihara’s Unweighed Grading System, treatment score after 3weeks was marked higher than that before treatment and treatment score after final treatment was also marked higher than that after 3weeks within each group. 4. After final treatment, Bee Venom Pharmacopuncture therapy group showed signficant difference on Gross Grading System of House-Brackmann, Yanagihara’s Unweighed Grading System compared with Acupuncture therapy group. Conclusions : Bee Venom Pharmacopuncture therapy can be available for relieving symptoms related with peripheral facial paralysis.

Objectives : This study was to evaluate the influence of dysgeusia on prognosis of peripheral facial paralysis. Methods : We investigated 40 cases of patients with Peripheral Facial Paralysis, and classified them as existence of dysgeusia. we evaluated the treatment effect of each group by using Gross Grading System of House-Brackmann, Yanagihara's Unweighed Grading System before treatment and after final treatment. Results : 1. Postauricular pain showed the highest frequency in symptoms at onset. 2. As a result of evaluation by using Gross Grading System of House-Brackmann, Yanagihara's Unweighed Grading System, treatment score after final treatment was marked higher than that before treatment within each group. 3. After final treatment, non-dysgeusia group showed signficant difference on Gross Grading System of House-Brackmann, Yanagihara's Unweighed Grading System compared with dysgeusia group. Conclusions : These results suggested that non-dysgeusia group should be get better than dysgeusia group in the patient with peripheral facial paralysis.
