본 연구에서는 유기물 발광 다이오드(OLED)의 효율을 향상시키기 위하여 버퍼층 역할을 하는 PEDOT:PSS (poly(3,4-ethylenedioxythiophene) : poly styrene sulfonate)의 공정조건을 확립하고 두께에 따른 전기적 광학적 특성을 조사하였다. PEDOT:PSS는 spin coating 방법으로 증착을 하였으며, 흘효과측정을 통하여 ITO기판과 유기버퍼층이 코팅된 기판의 전하운반체의 이동도와 전류-전압 특성을 조사하였다. 그리고 UV-vis spectrometer를 이용하여 광투과도, 굴절률, 밴드갭을 측정하였고 SEM을 이용하여 시료의 표면도 관찰하였다. 유기물 버퍼층(PEDOT:PSS)의 두께가 얇을수록 정공의 이동도가 향상됨을 알 수 있었다.

ICP-CVD(Inductively Coupled Plasma-Chemical Vapor Deposition)를 이용하여 플라즈마 처리에 따른 Al이 도핑된 ZnO(AZO) 박막의 표면 부착력과 굴절율, 표면거칠기에 관한 연구를 하였다. 플라즈마 처리는 인가전압, 시간을 변수로 하였고 반응 가스는 Ar을 사용하였다. 표면조성은 AFM, 광학적 특성은 UV-Vis 분광계를 이용한 광투과도 측정으로부터 굴절률과 밴드갭을 조사하였고 표면 부착력은 접촉각 분석기(제조사:Kruss)를 사용하여 조사하였다. 플라즈마 처리 시간이 길어짐에 따라 박막 표면의 거칠기가 커지고 부착력은 증가하는 것으로 나타났다.

This study is designed to evaluate the effects of an oriental herbal medication namely Danggwihwahyeolsan-gamibang and Gami-Jeonssibaekchulsan, on ulcerative colitis. Subject: A patient diagnosed ulcerative colitis who're not improved through western medication. Methods: The Clinical data was analyzed on a pastient with ulcerative clitis due to Changpung(腸風) resulted from Hanyeolchakjab(寒熱錯雜), whose symptoms were combined diarrhea, abdominal pain et al. The patient visited at the internal medicine department of Daegu Haany University affiliated Daegu Oriental Hospital on May 18. 2007 to June 25. 2007. The improvement of symptoms were checked by Seo Colitis Activity Index(AI).

This study was aimed to obtain epidemiological information of cancer patients treated with Oriental medicine. 58 breast and gynecological cancer patients treated in Cancer Center of Daeguhanny Oriental Hospital from August 2012 to August 2013 were reviewed. Careful investigations were done by categorizing these patients by their origin, stage, treatment, conventional treatment type, chief complaint, etc. In tumor origin, breast cancer showed the largest proportion in total patients(74.1%) and inpatients(81.8%). 63.8% of the patients' tumors were stage III and IV. 48.3% of patients visited Oriental hospital for combination treatment with conventional medicine. 91.4% of the patients have under 5 years of cancer duration. Their cheif complaints are general weakness, postoperative pain and abdominal discomfort in general. This study presented the characteristics of breast and gynecological cancer patients treated by Oriental medical therapies, and thus would be valuable for futher studies of Oriental medical cancer treatments.

Objectives: This study is a report of the clinical application of traditional Korean medicine on ataxia with cerebellar atrophy. Methods: The ataxia in this case occurred 5 years ago. The symptoms had been getting worse until the patient came to hospital. The MRI of this patient showed atrophy of the cerebellum. We measured the state of this case with the Korean version of the Berg Balance Scale (K-BBS), before and after treatment and Numeric Rating Scale-11 (NRS-11) of the symptoms, every week. We treated the case with traditional Korean medicine such as acupuncture and Gamiyukmijihwang-tang. Results: After treatment, the score of K-BBS increased, while the score of NRS-11 decreased. Conclusions: According to this study, traditional Korean medicine is effective for controlling ataxia caused by cerebellar atrophy.

Objectives : The purpose of this study is to show the clinical effect of Korean Medical Treatments for Tinnitus with Sudden Sensory Neural Hearing Loss. Methods : The patient was treated by Korean Medical Treatments for 10weeks. The effect of treatments on tinnitus was measured with Visual Analogue Scale(VAS) and Korean Tinnitus Handicap Inventory(K-THI). And the effect of treatments on sudden hearing loss was measured by VAS. Results : VAS of Tinnitus was decreased from 10 to 3 points and K-THI score was decreased from 70 to 26 points. VAS of hearing loss was decreased from 9 to 8 points. Conclusions : Korean Medical Treatments are effective on Tinnitus.

1-and 2-Bromopropane were reported as the causative agents for reproductive toxicity and immunotoxicity. The glutathione (GSH) metabolites resulting from in vitro treatment of 1- and 2-bromopropane were detected, identified and characterized. For the facile identification, expected GSH metabolites rormed by 1- and 2-bromopropane were chemically synthesized as reference materials (positive controls) and characterized by $^1H$-NMR, $^13C$-NMR, HPLC and LC/MS/MS. The treatment of GSH and S-9 fraction with 1- or 2-bromopropane at a physiological condition (pH 7.4, $37^\times$) for 1hr produced GSH metabolites, which were identified by UV, HPLC and ESI LC/MS/MS analyses.

Objectives : Many studies have investigated the electric specificity of meridian and acupoint. However, the definition about the real substance of 'Ki(Qi)' that flows in the meridian has not been established yet. The authors hypothesized that the 'Ki(Qi)' may be the very 'bioelectricity' of western medicine, from two common features that they are not visible with naked eyes and that they function in the living body only. Methods : 20 healthy adults participated in this study. Heart rate was measured before and after exercise. Acupuncture was performed at PC6 immediately after exercise with counter balance in the first experiment. In the second experiment, acupuncture group was further divided to the three groups, i.e. glove acupuncture group, manual acupuncture group, and NaCl acupuncture group. In the glove group, acupuncturist put on the two folds of latex gloves to block bioelectric currents between the acupuncturist and subject. In the NaCl group, acupuncturist had his fingertips wet with NaCl solution. Results : Exercise increased Heart Rate and acupuncture at PC6 inhibited this increase. In the second experiment, the significant difference compared to the comtrol group was the most in NaCl acupuncture and the least in Glove acupuncture. However, there was no significant difference between three groups. Conclusions : The results of this study seem to be deficient as a conclusive evidence for the hypothesis that the 'Ki(Qi)' of Korean Medicine is the 'bioelectricity' of western medicine.
