The studies look at the causes, pathology, symptom, diagnosis, treatment of rheumatoid arthritis in the sight of east-western medicine. Following are the results : 1. Rheumatoid arthritis korean-medically belongs to symptom such as Bi(痺), Poung Bi(風痺), Tong Poung(痛風), Youk Jeol Poung(歷節風), Bak Hoe Poung(白虎風), Bak Hoe Youk Jeol Poung(白虎歷節風), etc. 2. The causes of Rheumatoid arthritis are endopathic and exopathic : endopathically it tis related to Chil Jeong(七情) and visceral imbalance, and exopathically it is related to Euk Eum (六淫) and environmental factors. 3. To figure out rheumatoid arthritis, we need to diagnose first the joint symptom and the general body condition, we need about 6 weeks to get the exact decision after the serologic test, the immune and inheritance test, the synovium test. 4. There are four kinds of treatments for rheumatoid arthritis : medicin, acupucture and moxibustion, suction cup and purging away the blood, physical therapy. Cheong Eol So Bi(淸熱消痺) can be used for the acute stage and Jang Bu Seong Shai(臟腑盛衰) is to be considered for the chronic stage. 5. Rheumatoid arthritis should be constantly treated to prevent the patient from the deformity of joint complication.

본 논문에서는 얼굴 영상으로부터 얼굴인식을 위한 눈동자를 검출하기 위한 방법을 제안하고자 한다. 제안된 방법은 분리 필터를 사용하여 홍채의 후보가 되는 영역을 구한 후 양자를 잇는 선분의 길이 및 기울기의 허용치 안에 있는 모든 영역에 대해 본 논문에서 제안한 방식으로 그 값을 계산한다. 이 값은 영역의 근방영역에서 홍채의 경계선에 대응하는 원을 허프변환으로 구했을 때 후보 영역의 원에서의 후보 영역과 인접하면서 분리된 영역 내의 평균 휘도 값 및 영역을 포함한 부분화상과 눈의 템프릿 사이의 정규화된 상관계수를 사용하여 계산된다. 그리고 그 값을 최소로 하는 영역들을 택하여 이것을 양눈의 홍채로 검출한다. 안경을 쓰지 않은 총 150장의 얼굴영상을 사용하여 실험한 결과 최대 97.3%, 최소 95.3%의 성공률을 얻을 수 있었으며, 약간의 오차를 허용한 경우에는 최대 99.3%, 최소 96.7%의 성공률을 얻을 수 있었다.

Phantom limb pain is a painful sensation from an absent limb. The onset of pain is generally early, with 75% of patients developing pain within the first few days after amputation. The frequency and duration of attacks tend to be reduced with time, although the prevalence and intensity remain constant. We report here a case of a 38-year-old man who exhibited the signs and symptoms of phantom limb pain due to the above-knee amputations of both legs. He was not responded to opioid therapy and a continuous intravenous infusion of ketamine, an N-methyl-D-aspatate receptor antagonist, reduced his severe pain.

A 45-year-old-male who had underlying ulcerative colitis and presented with fever and dry cough. Initially, the patient was considered to have invasive aspergillosis due to a positive galactomannan assay. He was treated with amphotericin B followed by voriconazole. Nevertheless, the patient deteriorated clinically and radiographically. The lung biopsy revealed eosinophilic pneumonia, and ELISA for Toxocara antigen was positive, leading to a diagnosis of pulmonary toxocariasis. After a 10-day treatment course with albendazole and adjunctive steroids, the patient recovered completely without any sequelae. Pulmonary toxocariasis may be considered in patients with subacute or chronic pneumonia unresponsive to antibiotic agents, particularly in cases with eosinophilia.

NiCo silicide films have been fabricated from $300{\AA}-thick\;Ni_{1-x}Co_{x}(x=0.1\sim0.9)$ on Si-substrates by varying RTA(rapid thermal annealing) temperatures from $700^{\circ}C\;to\;1100^{\circ}C$ for 40 sec. Sheet resistance, cross-sectional microstructure, and chemical composition evolution were measured by a four point probe, a transmission electron microscope(TEM), and an Auger depth profilemeter, respectively. For silicides of the all composition and temperatures except for $80\%$ of the Ni composition, we observed small sheet resistance of sub- $7\;{\Omega}/sq.,$ which was stable even at $1100^{\circ}C$. We report that our newly proposed NiCo silicides may obtain sub 50 nm-thick films by tunning the nickel composition and silicidation temperature. New NiCo silicides from NiCo-alloys may be more appropriate for sub-0.1${\mu}m$ CMOS process, compared to conventional single phase or stacked composit silicides.

The content and composition of tocopherol were analyzed in peanuts produced in Korea. The tocopherol assay was consisted of an extraction with n-hex-ane:isopropanol mixture followed by high pressure liquid chromatography with fluorescence detection. Tocopherol content was higher in leaves and seeds but lower in seed coats and shells. $\alpha$-/${\gamma}$- Tocopherol ratio was as low as 0.53 in seeds and as high as 22.5 in shells. Tocopherol content in seeds of nine varieties ranged from 142 to 220 ng/mg dry weight, and the $\alpha$-/${\gamma}$-tocopherol ratio from 0.40 to 0.75. Tocopherol content decreased by 18% but $\alpha$-/${\gamma}$-tocopherol ratio increased by 44% in roasted seeds. The results indicate that the level of tocopherol in Korean peanut varieties is moderate and the ratio of $\alpha$- to ${\gamma}$-tocopherol is low.

대용량의 자료가 생산됨에 따라 데이터를 효율적으로 저장, 관리, 이용할 수 있는 데이터 웨어하우스의 역할이 중요하게 되었고, 그에 따라 자료 처리 기법의 개발은 필수 과제가 되었다. 품질 평가와 오류 판단, 결측 보정의 자료 처리 과점은 자료의 신뢰도를 판단하고 활용도를 높일 수 있는 과정으로 매우 중요하다. 본 논문에서는 우리나라의 실제 교통상황을 반영하고 평가 기준의 오차를 줄이면서 더욱 간단 명료한 평가 계산식을 도입하여 효율적인 품질평가와 오류판단, 결측 보정의 자료 처리 기법을 제안한다. 또한 오류 판단 기준에 새로운 파라미터론 도입하여 교통 연구자의 요구 사항을 반영할 수 있게 하였다. 결측 보정 과정은 여러 기법을 연구하고 기존의 결측 보정 기법에 입력 변수를 추가하여 실제 대용량의 교통 자료에 적용하였다. 그리고 교통 자료가 저장되는 데이터베이스에 직접 접근하여 결측 보정과정을 수행하도록 PL/SQL로 구현하였으며, 이를 통해 교통 연구자에게 쉽고 다양한 방법으로 결측 보정을 수행하고 그 결과를 이용하여 다양한 교통 정보를 가공할 수 있는 환경을 제공하였다.

Correlations between the amount of DAW (Dry Active Waste) generated from present Korean PWRs and their operating parameters were analyzed. As the result of multi-variable linear regressions, a model predicting the volume of DAW using the number of shutdowns ( $f_{FS}$ ) and total personnel exposure ( $P_{\varepsilon}$) was derived. Considering one standard error bound, the model could successfully simulate about 8575 of the real data. In order to predict the amount of DAW to be generated from a KNGR another model was derived by taking into account the additional volume reduction by supercompaction system. In addition, the volume of WAW (Wet Active Waste) to be generated from KNGR (Korean Next Generation Reactor) was calculated by considering conceptual design data and replacement effect of radwaste evaporator with selective ion exchangers. Finally, total volume of SRW (Solid Radioactive Waste) to be generated from KNGR was predicted by inserting design goal values of $f_{FS}$ and $P_{\varepsilon}$ into the model. The result showed that the expected amount of SRW to be generated from KNGR would be in the range of 33~44㎥. $y^{-1}$ . It was proved that the value would meet the operational target of KNGR proposed by KEPCO, that is, 50㎥. $y^{-1}$ .

The results of evaluating steel corrosion in concrete containing chloride content of various levels indicated that the more chloride content in concrete leads to the lower potential and higher corrosion current density. However, the open circuit potential of steel varied with time and exposure condition, and the corelation between the open circuit potential and corrosion current density was not obvious. In order to determine the critical threshold content of chloride of steel corrosion in concrete, the concept of average corrosion current density was employed. The range of critical chloride content in portland cement concretes was about $1.56{\sim}1.77%$($Cl^-$, %, wt of cement content) along with water-cement ratio, and higher water-cement ratio resulted in reduction in critical threshold chloride content.
