  • It is essential to describe information on a person, family or corporate body that is responsible for creation of archives in providing archival contextual information. This paper discusses the establishment of contextual information based on the authority control of creators of archives by using international standards such as ISAAR (CPF) : International Standard Archival Authority Record for Corporate Bodies, Persons, and Families, Second edition and EAC(Encoded Archival Context). It introduces the LEAF(Linking and Exploring Authority Files) Project in Europe, which presents the model for exchanging and sharing of authority data between libraries, archives and museums by employing EAC. The concluding remarks stress limitations associated with establishing and exchanging of authority files and requirements for the establishment of archival contextual information nationally.

  • Inflammatory mediators such as interleukin-1 (IL-1), tumor necrosis $factor-{\alpha}\;(TNF-{\alpha}),\;interferon-{\gamma}\;(IFN-{\gamma})$ and lipopolysaccharide (LPS) are thought to play major roles in joint diseases such as a rheumatoid arthritis (RA), and there is considerable evidence playing a role for these cytokines in osteoarthritis (OA). Therefore, we have studied the effects on anti-inflammation and analgesic by ethyl acetate fraction from 70% ethanol extract of Artemisia capillaries (EAC). As a positive control, apigenin, which is known as an anti-inflammatory agent as an iNOS inhibitor, was used and showed the dose-dependent inhibitory effect. EAC showed strong inhibitory efficacy against cytokine-induced proteoglycan degradation, $PGE_2$ production, nitric oxide (NO) production, and matrix-matalloproteinases (MMPs) expression in rabbit articular chondrocyte. In the writhing test induced by acetic acid, EAC $(200{\sim}400\;mg/kg)$ exhibited a dose-dependent inhibition of writhing. The results indicate that EAC have anti-inflammatory and analgesic activities, and could be a good herbal medicine candidate for curing of RA and/or OA.

  • Design factors such as design objects establishment, analysis, synthesis, production, test and evaluation should be educated in a systematic way. Also design ability to reflect practical restrictive conditions such as industrial standards, economic feasibility, environmental impact, aesthetics, safety and reliability, ethical impacts and social impacts should be cultivated. In this paper, we explain the meaning of these terms and propose a systematic engineering design education framework satisfying Korean engineering education accreditation criteria. We also present a simple implementation in information network engineering.

  • The plant Bryonia laciniosa (Family: Cucurbitaceae) has been indicated for the treatment of various diseases one among which is cancer. The purpose of this study was investigating experimentally the possible anti-tumor effect and antioxidant role of Bryonia laciniosa leaves in animal model. The methanol extract of Bryonia laciniosa (MEBL) administered at the doses of 62.5, 125 and 250 mg/kg in mice for 14 days after 24 h of tumor inoculation. The effect of MEBL on the growth of transplantable murine tumor, life span of EAC bearing mice, hematological profile and liver biochemical parameters (lipid peroxidation, antioxidant enzymes) were estimated. Treatment with MEBL decreased the tumor volume and viable cell count thereby increasing the life span of EAC bearing mice and brought back the hematological parameter more or less normal level. The effect of MEBL also decreases the levels of lipid peroxidation and increased the levels of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). The present work indicates that the methanol extract of Bryonia laciniosa exhibited significant antitumor and antioxidant activity in vivo.

  • The purpose of this study was to survey the actual state of engineering ethics curriculum in engineering college. This study was carried out through literature review and survey to accomplish the purpose. The subjects for the survey were 31 lecturer from 14 colleges that accrediated by ABEEK and prepare accrediatation. The results of this study were as follows. EAC(Ethics Across the Curriclum) was introduced in Engineering Ethics Education. There were a lot of students in a lecture and the plural lecturers were not appoined. In objectives of education, it was surveyed that focused in engineering situation above all theory of ethics and theoritical contents are entering into large part of engineering ethics education. The lecture method and paper-pencil assessment were used mainly in the lecture.

  • In a power system, an out-of-step condition causes a variety of risk such as serious damage to system elements, tripping of loads and generators, mal-operation of relays, etc. Therefore, it is very important to detect the out-of-step condition and take a proper measure. Several out-of-step detection methods have been employed in relays until now. Most common method used for an out-of-step detection is based on the transition time through the blocking impedance area in R-X diagram. Also, the R-R dot out-of-step relay, the out-of-step prediction method and the adaptive out-of-step relay using the equal area criterion (EAC) and Global Positioning Satellite (GPS) technology have been developed. This paper presents the out-of-step detection algorithm using the time variation of the complex power. The complex power is calculated and the mechanical power of the generator is estimated by using the electrical power, and then the out-of-step detection algorithm which is based on the complex power and the estimated mechanical power, is presented. This algorithm may detect the instant when the generator angle passes the Unstable Equilibrium Point (UEP). The proposed out-of-step algorithm is verified and tested by using Alternative Transient Program/Electromagnetic Transient Program (ATP/EMTP) MODELS.
