This study was carried out to investigate the dose-dependent effect of jasmonic acid on both the adventitious root growth and the accumulation of various eleutherosides in the Eleutherococcus senticosus bioreactor culture. The highest biomass production (4.6 g DW/L) was observed in the absence of jasmonic acid and the root growth was significantly decreased by increasing the jasmonic acid concentration. However, jasmonic acid stimulated the production of both eleutheroside B, E and $E_1$. The highest level of eleutheroside B and E ($476.3{\mu}g/g\;DW$ and $676.0{\mu}g/g\;DW$) was obtained by 0.5 mg/L jasmonic acid treatment, while eleutheroside $E_1$ was accumulated at the highest level by 0.01 mg/L jasmonic acid treatment. The highest content of total eleutheroside was $2468.6{\mu}g/L$ when 0.01 mg/L jasmonic acid was applied. In addition, when the adventitious roots were cultured with 0.01 mg/L jasmonic acid, the highest levels of eleutheroside B, E and $E_1$ were observed at the 6th, 8th and 4th day of culture, respectively.

The two main purposes of this paper are to 1) investigate critical components of university information systems for information resources management, 2) develop a comprehensive framework model of university information systems for e-Business Era. Through a literature review and by employing group decision making techniques with managers of K University, critical components for developing university information systems were identified. The critical components of university information systems are 1) academic affaires. 2) general administration. (3) research administration. (4) information services. (5) management support, (6) cyber education. (7) knowledge management, (8) e-library. (9) mobile service. and (10) IT infrastructures. In the second stage. by employing IT experts in K University and other institutes. a comprehensive framework of university information systems for e-Business era was developed. The comprehensive framework shows that major components for university information resources management are (1) information infrastructure. (2) common operating environments. (3) applications/information services. The results of this study expect to help managers. who are in charge of university information systems. plan to develop information systems based on the framework proposed in this paper.

하천에 대한 수질해석을 위해 범용적으로 사용되는 QUAL2E 모형은 대상구간에 유사한 수리 특성을 가지는 구간(reach)을 설정하여 주어진 유량에 대해 동일한 수심과 유속을 가지도록 구성되어 있다. 하지만 실제 자연하도에서는 여러 가지 수공구조물이나 지형변화로 인해 흐름변화가 매우 다양하게 발생하고 있다. 본 연구에서는 범용적으로 사용되고 있는 DWOPER 모형이나 HEC-RAS 모형과 같은 1차원 수리해석모형의 부등류 모의결과를 QUAL2E 모형에서 활용함으로써 실제 하천에서 발생하는 국부적인 흐름특성을 수질해석에 반영할 수 있는 수리연계모듈을 개발하였으며, 이를 한강의 팔당댐 하류구간에 대해 적용하였다.

In Korean waters, the cirolanid isopod, Eurydice longiantennata Nunomura and Ikehara, 1985 has been reported only from the subtidal zone of Jeju island. We obtained the mitochondrial cytochrome c oxidase subunit I (COI) sequences of this species and determined the DNA barcoding data of E. longiantennata based on a genetic comparison of E. longiantennata and its congeners. The intra-specific genetic distance between the three COI sequences of E. longiantennata ranged from 0 to 0.6%. The inter-specific distances between E. longiantennata and other cirolanid isopods ranged from 24 to 33.2%. In this study, we provided the DNA information of E. longiantennata with a morphological diagnosis and images of the species.

This paper reviews the distinctive characteristics between e-Trade and e-Commerce in view of commercial arbitration in Korea and explores several improvements for the role of commercial arbitration. As the volume of e-Trade and e-Commerce has expanded day by day, there will be more disputes between traders no matter where the commerce may occur. But despite increasing of the disputes relating to e-Commerce transaction, it seems that the role of commercial arbitration has been shrunk instead. Korea needs to improve the role of commercial arbitration in order to meet and lead the age of u-Trade Hub(u-TH) service and to adopt an offensive or active attitude when arbitration used. Moreover, it is suggested that the competence of arbitration should not only be intensified more precisely but also be redesigned more systematically. Korea should take advantage of arbitration resources actively such as arbitrators as human resource and experiences as knowledge assets and also prepare the policy for sharing those arbitration resources between arbitrators more effectively.

The purpose of this study is to identify the problems of the e-book composition provided by the Comprehensive Reading Education Support System and to propose a service improvement plan related to the establishment of e-books in school libraries as educational resources based on practical issues and perceptions experienced by teacher-librarians. As a research method, the composition of the collection of 3,002 e-books supported by the Busan Comprehensive Reading Education Support System as a reading education platform of the school library was analyzed based on the Korean Decimal Classification. Based on this, two focus group interviews (FGI) were conducted with 4 elementary teacher-librarians and 5 secondary teacher-librarians working in Busan. The result of this study can be used as basic data to support students' reading activities using e-books as educational resources and to form an efficient e-book collection in school library.
