The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

고주파수대역에 적용되는 Fe-( BN, Si₃N₄)박막의 미세구조와 자기적특성에 관한 연구

We have investigated the magnetic properties of FeBN thin films deposited by using RF magnetron sputtering and Fe-BN composite target. It was investigated that the area fraction of BN chips on the Fe target and partial pressure of nitrogen was the main factors influencing the soft magnetic properties and resistivity of FeBN thin film. The low addition of N₂increases significantly the soft magnetic properties and electrical resistivity. The good soft magnetic properties are obtained at N₂partial pressure of 5%, but futher increase in N₂ partial pressure degrade the soft magnetic properties due to formation of nitrides such as Fe₄N, Fe₂∼₃N. In a sputtering process, as the area fraction of BN increases, FeBN thin films fabricated at the area fraction of 0.25 exhibt soft magnetic properties (Bs∼17kG, Hc∼10e, μ∼1000).

The experiments were conducted to determine the factors such as light and darkness, phytohormone and seed coat, influencing on seed germination of Bidens tripartita L. and B. frondosa. The seeds of both species were germinated when seed coat was damaged and weakened GA3 and BA stimulated germination of both species but ABA and IAA had no effect on germination of them, which ranged 50.0% to 80.0%. In B. forndosa, when inner layer of seed coat was removed, germination was highly promoted up to 96.7% compared with 10.0% germination rate in another treatments.

Changes in the cerebral white matter (leukoaraiosis;LA) are detected with increasing frequency by computed tomography (CT) and magnetic resonance imaging (MRI) in elderly patients with diabetes mellitus and hypertension. The purpose of this study is to determine whether the severity of retinopathy is correlated with degree of LA in patients with hypertension. Twenty-three consecutive patients with patients with hypertension admitted in the department of neurology were evaluated for degree of LA and severity of retinopathy. 8patients were 15female. The age distribution was between 52 and 85 years(mean 69.1years). The duration of hypertension was between 1 and 30 years(mean8.2 years). The degree of LA was correlated with severity of hypertensive retinopathy(p<0.05), especially in relatively young patient, short periods of disease, and female paitents(p<0.05). We can make a rough estimation of degree of LA with fundus examination without CT or MRI evaluations in hypertensive patients, especially in relatively young and female patients with short durations of disease. However, more broad study should be made for these value and relationship.

Background: The incidence and causative dermatophytes of tinea capitis has been changed with time. Objective: The purpose of this study was to investigate the clinical and mycological features of tinea capitis in Taegu. Methods: We evaluated the clinical and mycologic aspects of tinea capitis in 39 patients registered in Yeungnam University Hospital from January 1981 to June 1998. Results and Conclusion: The incidence of tinea capitis was 1.3% of 3,077 total dermatophytoses. The ratio of male to female patients was 1.6:1. Although most of the patients were children under the age of If, adult patients with tinea capitis were 23.1% of the cases. Frontal scalp was the most frequent site of tinea capitis. The most common causative organism of tinea capitis was Microsporum canis. Trichophyton rubrum and Trichophyton verrucosum were isolated, also.

Background : This study was performed to evaluate the clinicopathologic features and comparision of correlation factor of FDG uptake on hepatocellular carcinoma(HCC) patients. Methods: We retrospectively studied 61 HCC patients who studied 18[F]FDG-PET at department of surgery of Gospel hospital, Kosin university college of medicine between December 2004 and May 2008. We had analyzed age, sex, etiology of HCC, Child-Pugh classification, serum AFP, size of tumor, number of tumor, CLIP score, histopathologic classification(WHO classification, Edmonson calssification), FDG uptake and PET SUV, retrospectively. Statistical analyses were performed using the cross table Chi-square test and independent sample t-test. Results: FDG uptake was found in 39 patients of 61 HCC patients (63.9%), There were no significant differences except for size of tumor correlation factor of FDG uptake in total HCC patients with regard to sex, Child-Pugh classification, serum AFP, number of tumor, CLIP score and WHO classification. Conclusion: The size of tumor(≥5cm) was a correlation factor of FDG uptake in total HCC patients.

FeTaNC 미세결정박막의 연자기 특성에 관한 연구

申東勳,崔雲,金亨駿,高兌赫 弘益大學校 科學技術硏究所 1996 科學技術硏究論文集 Vol.7 No.1

Magnetic properties and microstructures of FeTaNC thin films, which were deposited by magnetron reactive sputtering method, were investigated as a function of CH₄ and N₂ gas partial pressures. Magnetic properties of FeTaNC films were depended on total reactive gas pressures as well as CH₄/N₂ pressure ratios. For reactive gas partial pressures of 5 ∼ 10 %, optimum magnetic properties were observed in the FeTaNC films with proper CH₄/N₂ ratio. On the other hand, at 15% of gas partial pressure, FeTaN and FeTaC films showed superior properties to FeTaNC films. Above 15%, the magnetic properties of films rapidly degraded due to an excess incorporation of C and/or N atoms. Excellent soft magnetic properties of 17kG of Bs, 0.3 Oe of Hc, and 4000 of μ' (at 5 ㎒) were obtained in the FeTaNC films. The process windows of FeTaNC films which are showing good soft magnetic properties are larger than FeTa(N/C) films. High permeabilities of FeTaNC films could be explained by the Fe lattice distortion caused by N atoms, hence reduction of magnetic anisotopy. While precipitated TaN and TaC particles effectively supress the growth of α-Fe grains leading to a good soft magentic properties, FeN and FeC phases such as Fe3N, Fe4N, FexC have detrimental effects.

The purpose of this study was to assess the current materials, methods and difficulties according to the year of licence and educational background of Korean dentists in Class Ⅱ direct composite resin restorations. Total 17 questions were included in the questionnaire. Questions were broadly divided into two parts first, operator's information and second the materials and methods used in Class Ⅱ posterior composite restoration. The questionnaire was sent to dentists enrolled in Korean Dental Association via e-mail. Total 12,193 e-mails were distributed to dentists. 2,612 e-mails were opened and 840 mails (32.2%) were received from respondents. The data was statically analyzed by chi-square test using SPSS(v 120.1 SPSS Inc. Chicago. IL USA). Male dentists among respondents was 79% 60.3% of the respondents acquired their licences recently (1998-2007) and 77% practiced in private offices 83.4% have acquired their knowledge through school lectures conferences and seminars. For the Class Ⅱ restorations gold inlays were preferred by 65.7% of respondents while direct composite resin restorations were used by 12.1% amalgam users were only 4.4% of respondents. For the restorative technique 74.4% of respondents didn't use rubber dam as needed. For the matrix. mylar strip (53.4%), metal matrix (33.8%) and Palodent system (6.5%) were used 99.6% of respondents restored the Class Ⅱ cavity by incremental layering. Obtaining of the tight interproximal contact was considered as the most difficult procedure (57.2%) followed by field isolation (21%). Among various bonding systems, 22. 6% of respondents preferred SE Bond and 20.2% used Single Bond. Z-250 was used most frequently among a variety of composite resins.
