■ Objectives The purpose of this case report is to show the effect of Traditional Korean Medicine(TKM) on a patient with poststroke urinary retention ■ Methods A stroke patient with urinary retention was treated with herbal medication(Paljungsan), acupuncture, electro-acupuncture and moxibustion. To evaluate the effect of TKM on post-stroke urinary retention, we observed voiding pattern and residual urine after voiding. ■ Results Maintenance of regular self voiding and decrease of residual urine after voiding were observed after the TKM treatment. ■ Conclusion This study showed the effect of TKM treatment on Urinary retention of stroke patient.

Objectives : The aim of this study was to observe variation of Bee Venom content from the collection period. Methods : Content analysis of Bee Venom was rendered using HPLC method by standard melittin Results : Analyzing melittin content using HPLC, 478.97mg/g at june , 493.89mg/g at july, 468.18mg/g at August and 482.15mg/g was containing in Bee Venom at september. So the change of melittin contents was no significance from June to September. Conclusion : Above these results, we concluded carefully that collecting time was not important factor for the quality control of Bee Venom, restricted the period from June to September.

Oil hydraulic piston pumps are being extensively used in the world, because of simple design, light weight and effective cost etc. An oil hydraulic pump is likely to have serious problems of high leakage, friction and low energy efficiency according to large time use. In the oil hydraulic piston pumps the clearance between the valve block and piston plays an important role for volumetric and overall efficiency. In this paper, the wear property of the SACM645 material used the hydraulic piston pump has been work out by experimentation with variable heat treatment. To investigate the effect according to the piston surface condition, seven different types specimen were prepared. From the wear test results, induction hardening and nitration were definitely superior to the others. On the whole, nitration was estimated for high strength material to wear resistance.

We designed new anthracene-based host material to increase color purity as well as device efficiency. The new blue host, 9,10-bis(2,4-dimethylphenyl)anthracene (BDA), has highly twisted structure and wide band gap due to ortho interaction between anthracene and introduced 2,4-dimethylphenyl substituents. BDA exhibited deep blue fluorescence in solution (${\lambda}_{max}$ = 410 nm) and in solid state (${\lambda}_{max}$ = 429 nm), respectively, with the wide optical band gap (E = 3.12 eV). Blue-light-emitting OLEDs using obtained host and 2% Flu-DPAN as emitter showed 8 cd/A of high efficiency as well as high color purity [CIE coordinates = (0.15, 015)].

The purpose of this study was to investigate extract from mixed culture with Trichloloma matsutake mycelium in oriental medicine and cereal medium(OCM) to develop new material for pharmaceutical products and medicinal food. To evaluate of physiological activity of OCM extracts, we examined ${\beta}$-glucan contents, SOD-like activity, nitric oxide production and cytotoxicity by MTT assay. ${\beta}$-glucan contents was found to be 52.85% for crude polysaccharide of hot water extracts of OCM(HEE) and 49.74% for crude polysaccharide of ultra sonic waves, micro waves, and micro bubble extracts of OCM (UEE). SOD like activity was showed UE 74.66%, HE 67.16%, UEE 31.34%, HEE 26.10%, respectively. NO production of UEE and HEE, at LPS 1 ug/mL, 1 mg/mL UEE showed 66.62 uM and HEE 45.68 uM. at LPS 10 ug/mL, 1 mg/mL UEE showed 63.91 uM and HEE 51.74 uM. The inhibitory effect against HT1080 was increased dose-dependently in UEE.

Recently, there are a lot of study to alternate polycarbonate which is being used as storage material in CD, DVD. In this study, we alternated polycarbonate with glass. We observed the change of shape in a surface of the glass which was focused by Nd:YAG Laser. The change of shape and property was studied by thermal mechanical analysis (TMA), UV-Vis spectrometer, AFM and SEM. According to Laser power and quantity of additives, the Bump's size and shape are showed differently. In high energy, the Bump will be transformed into Pit. And also according to CTE, $T_d$ and absorption ratio of glass, difference between Bump and Pit is confirmed. From these investigation, we could control that the minimum size of bump which is more useful shape than pit's is about 1.3 $\mu$m, H 70 nm, and it is near same the spot size.

Lateral type poly-silicon field emitters were fabricated by utilizing the LOCOS (Local Oxidation of Silicon) process. For the implementation 'of an ideal field emission device with quasi-zero tunneling barrier, a new and fundamental approach has used conducted by introducing an intelligent carbon-based thin layer on the cathode tip surface via a field-assisted self-aligning of carbon (FASAC) process. Fundamental lowering of the turn-on field for the electron emission was feasible through the control of both the tip shape and surface barrier height.

The patient was a 69-year-old Korean male with Lewy's body dementia and insomnia. He was treated with acupuncture and a herbal medicine, Ukan-san. To evaluate insomnia, the patient's total sleeping time was recorded. The patient's sleeping time increased after the administration of the Korean medicine treatments. Treatment with Korean medicine may be effective in treating insomnia in cases of Lewy's body dementia.

The case of a 73-year-old Korean female with dysgeusia due to an acute left thalamic infarction is presented. The patient was treated with the herbal medicine Yanggyuksanhwa-tang, in addition to acupuncture and electronic acupuncture treatment. The filter-paper test and Oral Health Impact Profile-14, (OHIP-14) test were administered to evaluate dysgeusia. Post-treatment, the patient's dysgeusia improved. Korean medicine may be an effective treatment for dysgeusia caused by a thalamic infarction.

We describe the cases of two patients with chronic subdural hematomas who were treated with Oreong-san. The patients' symptoms improved, as verified by brain computed tomography imaging. Oreong-san may control membrane permeability by inhibiting the aquaporin channel of the outer membrane of a hematoma. We speculate that hydrostatic modulation is a key mechanism underlying the effectiveness of Oreong-san in the treatment of subdural hematomas.
